                          AIM DEVELOPING MARKETS FUND
   
                        PROSPECTUS -- SEPTEMBER 8, 1998
    
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Developing Markets Fund (the
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-ended, series, management investment
company. The Fund is a non-diversified portfolio which primarily seeks long-term
capital appreciation. Its secondary investment objective is income, to the
extent consistent with seeking capital appreciation. The Fund normally invests
substantially all of its assets in issuers in the developing (or "emerging")
markets of Asia, Europe, Latin America and elsewhere. A majority of the Fund's
assets ordinarily is invested in emerging market equity securities. The Fund
also invests in emerging market debt securities, which are selected based on
their potential to provide a combination of capital appreciation and current
income.
    
 
The Fund is designed for long-term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in equity and high yield, high
risk ("lower quality") debt securities that are predominantly speculative.
Investments of this type are subject to a greater risk of loss of principal and
interest. The Fund's investments in securities of issuers in developing markets
involves special considerations and risks that are not typically associated with
investments in securities of issuers in the United States or in other more
established markets. Investors should carefully assess the risks associated with
an investment in the Fund.
 
   
This Prospectus sets forth concisely the information about the Fund that
prospective investors should know before investing. It should be read and
retained for future reference. A Statement of Additional Information dated
September 8, 1998 has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated herein by reference. The Statement of Additional
Information is available without charge upon written request to the Trust at 11
Greenway Plaza, Suite 100, Houston, Texas 77046-1173 or by calling
1-800-347-4246. The SEC maintains a Web site at http://www.sec.gov that contains
the Statement of Additional Information, material incorporated by reference, and
other information regarding the Fund. Additional information about the Fund may
also be obtained from
http://www.aimfunds.com.

BY, ANY BANK, AND THE FUND'S SHARES ARE NOT FEDERALLY INSURED OR GUARANTEED BY

<TABLE>
<S>                            <C>                                               <C>
  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The dis-
                               tributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."
 
                               Class B shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such shares were purchased. Class B shares redeemed after six years from the date such
                               shares were purchased will not be subject to any contingent

                                  (Continued)
- --------------------------------------------------------------------------------
   
<TABLE>
<S>                            <C>                                               <C>
                               deferred sales charge. See "How to Redeem Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objectives. The Fund's net asset
                               value per share will fluctuate, reflecting fluctuations in the market value of its portfolio
                               holdings.
 
                               The Fund invests in foreign securities. Investments in foreign securities involve risks relating to
                               political and economic developments abroad and the differences between the regulations to which U.S.
                               and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings, and gains and losses realized on sales of securities. Securities of
                               foreign companies may be less liquid and their prices more volatile than those of securities of
                               comparable U.S. companies. The Fund normally invests substantially all of its assets in issuers in
                               emerging markets. Such investments entail greater risks than investing in issuers in developed
                               markets.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
 
                               The value of debt securities held by the Fund generally fluctuates inversely with interest rate
                               movements. Certain investment grade debt securities may possess speculative qualities. The Fund may
                               invest in below investment grade debt securities. Investments of this type are subject to a greater
                               risk of loss of principal and interest.

</TABLE>
    
 
- ------------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charges permitted by National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase; the charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges. "
    
 
   
(3) Expenses are estimated based on the fees and expenses the Fund is expected
    to incur during its initial fiscal year as an open-end fund and AIM's
    undertaking to limit the Fund's expenses (exclusive of brokerage
    commissions, taxes, interest and extraordinary expenses) to the annual rate
    of 2.00% and 2.50% of the average daily net assets of the Fund's Class A
    shares and Class B shares, respectively. Without reimbursements and waivers,
    "Other expenses" and "Total Fund Operating Expenses" are estimated to be
    0.65% and 2.13%, respectively, for Class A shares and 0.65% and 2.63%,
    respectively, for Class B shares. "Other expenses" include custody, transfer
    agent, legal and audit fees and other operating expenses. See "Management"
    herein and in the Statement of Additional Information for more information.
    
 
   
(4) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the example of a 5% annual return are required by regulations of the SEC
    applicable to all mutual funds. The 5% annual return is not a prediction of
    and does not represent the Fund's projected or actual performance.
    
 
   
(5) Assumes payment of maximum sales charge by the investor.
    
 
   
(6) Assumes deduction of the applicable contingent deferred sales charge.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

The table below provides condensed financial information concerning income and
capital changes for one share of G.T. Global Developing Markets Fund, Inc. (the
"Predecessor Fund") for the periods shown. This information is supplemented by
the financial statements and accompanying notes appearing in the Statement of
Additional Information.                    . The Predecessor Fund was a
closed-end investment company whose single class of shares traded on the New
York Stock Exchange ("NYSE"). On October 31, 1997, the Fund, which had no
previous operating history, acquired the assets and assumed the liabilities of
the Predecessor Fund. On that date, all shareholders of the Predecessor Fund
received Class A shares of the Fund. The fees and expenses of the Fund will
differ from those of the Predecessor Fund. The Fund's fiscal year end will be
October 31, rather than December 31, which was the Predecessor Fund's fiscal
year end.

PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
   
The Fund's primary investment objective is long-term capital appreciation; its
secondary objective is income, to the extent consistent with seeking capital
appreciation. The Fund normally invests substantially all of its assets in
issuers in the developing (or "emerging") markets of Asia, Europe, Latin America
and elsewhere. A majority of the Fund's assets normally are invested in emerging
market equity securities. The Fund may invest in the following types of equity
securities: common stock, preferred stock, securities convertible into common
stock, American Depository Receipts, Global Depository Receipts, rights and
warrants to acquire such securities and substantially similar forms of equity
with comparable risk characteristics. The Fund may also invest in emerging
market debt securities that will be selected based on their potential to provide
a combination of capital appreciation and current income. There can be no
assurance the Fund will achieve its investment objective.
    
 
For purposes of the Fund's operations, emerging markets consist of all countries
determined by the Sub-adviser to have developing or emerging economies and
markets. These countries generally include every country in the world except the
United States, Canada, Japan, Australia, New Zealand and most countries located
in Western Europe. See "Investment Objectives and Policies" in the Statement of
Additional Information for a complete list of all the countries that the Fund
does not currently consider to be emerging markets.
 
For purposes of the Fund's policy of normally investing substantially all of its
assets in issuers in emerging markets, the Fund will consider investment in the
following emerging markets:

</TABLE>
 
Although the Fund considers each of the above-listed countries eligible for
investment, it will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements for the Fund's assets, overly
burdensome repatriation and similar restrictions, the lack of organized and
liquid securities markets, unacceptable political risks or for other reasons.
 
As used in this Prospectus, an issuer in an emerging market is an entity (1) for
which the principal securities trading market is an emerging market, as defined
above, (2) that (alone or on a consolidated basis) derives 50% or more of its
total revenues from business in emerging markets, provided that, in the
Sub-adviser's view, the value of such issuer's securities will tend to reflect
emerging market developments to a greater extent than developments elsewhere, or
(3) organized under the laws of, or with a principal office in, an emerging
market.
 
In selecting investments, the Sub-adviser seeks to identify those countries and
industries where economic and political factors, including currency movements,
are likely to produce above-average growth rates over the long term. The
Sub-adviser seeks those emerging markets that have strongly developing economies
and in which the markets are becoming more sophisticated. The Sub-adviser then
invests in those companies in such countries and industries that it believes are
best positioned and managed to take advantage of these economic and political
factors. The Sub-adviser believes that the issuers of securities in emerging
markets often have sales and earnings growth rates that exceed those in
developed countries and that such
 
                               Prospectus Page 7
<PAGE>
                          AIM DEVELOPING MARKETS FUND
growth rates may in turn be reflected in more rapid share price appreciation.
 
As opportunities to invest in securities in other emerging markets develop, the
Fund expects to expand and further broaden the group of emerging markets in
which it invests. In some cases, investments in debt securities could provide
the Fund with access to emerging markets in the early stages of their economic
development, when equity securities are not yet generally available or, in the
Sub-adviser's view, do not yet present an acceptable investment alternative.
While the Fund generally is not restricted in the portion of its assets that may
be invested in a single region, under normal conditions its assets will be
invested in issuers in at least four countries, and it will not invest more than
25% of its assets in issuers in one country. The Fund's holdings of any one
foreign currency together with securities denominated in or indexed to such
currency will not exceed 40% of its assets.
 
INVESTMENTS IN DEBT SECURITIES. The Fund may invest up to 50% of its total
assets in the following types of emerging market debt securities: (1) debt
securities issued or guaranteed by governments, their agencies,
instrumentalities or political subdivisions, or by government owned, controlled
or sponsored entities, including central banks (collectively, "Sovereign Debt"),
including Brady Bonds; (2) interests in issuers organized and operated for the
purpose of restructuring the investment characteristics of Sovereign Debt; (3)
debt securities issued by banks and other business entities; and (4) debt
securities denominated in or indexed to the currencies of emerging markets. Debt
securities held by the Fund may take the form of bonds, notes, bills,
debentures, bank debt obligations, short-term paper, loan participations,
assignments and interests issued by entities organized and operated for the
purpose of restructuring the investment characteristics of any of the foregoing.
There is no requirement with respect to the maturity or duration of debt
securities in which the Fund may invest.
 
There is no limitation on the percentage of the Fund's assets that may be
invested in debt securities that are rated below investment grade. Investment in
below investment grade debt securities involves a high degree of risk and can be
speculative. These debt securities are the equivalent of high yield, high risk
bonds, commonly known as "junk bonds." Debt securities in which the Fund will
invest may not be rated; if rated, it is expected that such ratings will be
below investment grade. See "Risk Factors -- Risks Associated with Debt
Securities" and "-- Risks Associated with Below Investment Grade Debt
Securities."
 
The Fund may invest in "Brady Bonds," which are debt restructurings that provide
for the exchange of cash and loans for newly issued bonds. Brady Bonds have been
issued by the countries of Albania, Argentina, Brazil, Bulgaria, Costa Rica,
Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria, Panama, Peru,
Philippines, Poland, Uruguay, Venezuela and Vietnam, and are expected to be
issued by other emerging market countries. As of the date of this Prospectus,
the Fund is not aware of the occurrence of any payment defaults on Brady Bonds.
Investors should recognize, however, that Brady Bonds do not have a long payment
history. In addition, Brady Bonds are often rated below investment grade.
 
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
 
Capital appreciation in debt securities may arise as a result of a favorable
change in relative foreign exchange rates, relative interest rate levels and/or
the creditworthiness of issuers.
 
ADDITIONAL INVESTMENT POLICIES
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy
for the Fund if it determines such a strategy to be warranted due to market,
economic or political conditions. Under a defensive strategy, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units such as
Euros) and/ or invest any portion or all of its assets in high quality money
market instruments of U.S. or foreign issuers. In addition, for temporary
defensive purposes, most or all of the Fund's investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund adopts a
temporary defensive posture, it will not be invested so as to directly achieve
its investment objectives.

<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
In addition, pending investment of proceeds from new sales of Fund shares or in
order to meet ordinary daily cash needs, the Fund may hold cash (U.S. dollars,
foreign currencies or multinational currency units) and may invest in foreign or
domestic high quality money market instruments. For a description of money
market instruments, see "Temporary Defensive Strategies" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
BORROWING AND REVERSE REPURCHASE AGREEMENTS. In connection with meeting requests
for the redemption of Fund shares, the Fund may borrow from banks or may borrow
through reverse repurchase agreements. The Fund also may borrow up to 5% of its
total assets for temporary or emergency purposes other than to meet redemptions,
but total borrowings may not exceed 33 1/3% of its total assets. However, the
Fund will not purchase securities while borrowings in excess of 5% of its total
assets are outstanding. Any borrowing by the Fund may cause greater fluctuation
in the value of its shares than would be the case if it did not borrow.
 
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash and agrees to repurchase the security in the
future at an agreed-upon price that includes an interest component.
 
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least 100% of the value of the
borrowed securities plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral if the borrower fails financially.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. To attempt to increase
return, the Fund may write call options on securities. This strategy will be
employed only when, in the opinion of the Sub-adviser, the size of the premium
the Fund receives for writing the option is adequate to compensate it against
the risk that appreciation in the underlying security may not be fully realized
if the option is exercised. The Fund also is authorized to write put options to
attempt to enhance return, although it does not currently intend to do so.
 
The Fund may also use forward currency contracts, futures contracts, options on
securities, options on currencies, options on indices and options on futures
contracts to attempt to hedge against the overall level of investment and
currency risk normally associated with its investments. These instruments are
often referred to as "derivatives," which may be defined as financial
instruments whose performance is derived, at least in part, from the performance
of another asset (such as a security, currency or an index of securities). The
Fund may enter into such instruments up to the full value of its portfolio
assets. See "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
 
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge its portfolio against movements in exchange rates.
 
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most emerging markets, to securities
denominated in such currencies or to securities of issuers domiciled or
principally engaged in business in such emerging markets. To the extent that
such a market does not exist, the Sub-adviser may not be able to effectively
hedge its investment in such markets.
 
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
 
                               Prospectus Page 9
<PAGE>
                          AIM DEVELOPING MARKETS FUND
stock indices to hedge against overall fluctuations in the securities markets or
in a specific market sector.
 
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or a specific market sector decline that could adversely affect the
Fund's portfolio. The Fund also may purchase index futures contracts and
purchase call options or write put options on such contracts to hedge against a
general market or market sector advance and thereby attempt to lessen the cost
of future securities acquisitions. Similarly, the Fund may use interest rate
futures contracts and options thereon to hedge the debt portion of its portfolio
against changes in the general level of interest rates.
 
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940, as amended
(the "1940 Act"), the Fund generally may invest up to 10% of its total assets in
the aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
 
Investment in other investment companies may involve the payment of substantial
premiums above the value of their portfolio securities and multiple layering of
fees and expenses and is subject to limitations under the 1940 Act and market
availability. The Fund does not intend to invest in other investment companies
unless, in the judgment of the Sub-adviser, the potential benefits of such
investment justify the payment of any applicable premium or sales charge. As a
shareholder in another investment company, the Fund would bear its ratable share
of that company's expenses, including its advisory and administration fees. At
the same time the Fund would continue to pay its own management fees and other
expenses. AIM and the Sub-adviser will waive their advisory fees to the extent
that the Fund invests in an Affiliated Fund.
 
PRIVATIZATIONS. The governments in some emerging markets have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain emerging markets, the ability of foreign entities such
as the Fund to participate in privatizations may be limited by local law or the
terms on which the Fund may be permitted to participate may be less advantageous
than those afforded local investors. There can be no assurance that governments
in emerging markets will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
 
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian bank and will mark to market daily such assets.
There is a risk that the securities may not be delivered and that the Fund may
incur a loss.
 
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may invest in fixed and floating
rate loans ("Loans") arranged through private negotiations between a foreign
entity and one or more financial institutions ("Lenders"). The majority of the
Fund's investments in Loans in emerging markets is expected to be in the form of
participations in Loans ("Participations") and assignments of portions of Loans
from third parties ("Assignments"). Participations typically will result in the
 
                               Prospectus Page 10
<PAGE>
                          AIM DEVELOPING MARKETS FUND
Fund having a contractual relationship only with the Lender, not with the
borrower. The Fund will have the right to receive payments of principal,
interest and any fees to which it is entitled only from the Lender selling the
Participation and only upon receipt by the Lender of the payments from the
borrower. In connection with purchasing Participations, the Fund generally will
have no right to enforce compliance by the borrower with the terms of the loan
agreement relating to the loan, nor any rights of set-off against the borrower,
and the Fund may not directly benefit from any collateral supporting the Loan in
which it has purchased the Participation. As a result, the Fund will assume the
credit risk of both the borrower and the Lender that is selling the
Participation.
 
In the event of the insolvency of the Lender selling a Participation, the Fund
may be treated as a general creditor of the Lender and may not benefit from any
set-off between the Lender and the borrower. The Fund will acquire
Participations only if the Lender interpositioned between the Fund and the
borrower is determined by the Sub-adviser to be creditworthy. When the Fund
purchases Assignments from Lenders, the Fund will acquire direct rights against
the borrower on the Loan. However, because Assignments are arranged through
private negotiations between potential assignees and assignors, the rights and
obligations acquired by the Fund as the purchaser of an Assignment may differ
from, and be more limited than, those held by the assigning Lender.
 
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. The Fund also may invest in
zero coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt, and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
"interest" in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the interest on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
may be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
 
INDEXED COMMERCIAL PAPER. The Fund may invest without limitation in commercial
paper that is indexed to certain specific foreign currency exchange rates. The
terms of such commercial paper provide that its principal amount is adjusted
upwards or downwards (but not below zero) at maturity to reflect changes in the
exchange rate between two currencies while the obligation is outstanding. The
Fund will purchase such commercial paper with the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency, but the amount of principal payable by the issuer at
maturity will change in proportion to the change (if any) in the exchange rate
between the two specified currencies between the date the instrument is issued
and the date the instrument matures. While such commercial paper entails the
risk of loss of principal, the potential for realizing gains as a result of
changes in foreign currency exchange rates enables the Fund to hedge against a
decline in the U.S. dollar value of investments denominated in foreign
currencies while seeking to provide an attractive money market rate of return.
The Fund will not purchase such commercial paper for speculation.
 
OTHER INDEXED SECURITIES. The Fund may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of other
securities, securities indices, currencies, precious metals or other commodities
or other financial indicators. Indexed securities typically, but not always, are
debt securities or deposits whose value at maturity or coupon rate is determined
by reference to a specific instrument or statistic. The performance of indexed
securities depends to a great extent on the performance of the security,
currency or other instrument to which they are indexed and also may be
influenced by interest rate changes in the United States and abroad. At the same
time, indexed securities are subject to the credit risks associated with the
issuer of the security, and their values may decline substantially if the
 
                               Prospectus Page 11
<PAGE>
                          AIM DEVELOPING MARKETS FUND
issuer's creditworthiness deteriorates. Indexed securities may be more volatile
than the underlying instruments. New forms of indexed securities continue to be
developed. The Fund may invest in such securities to the extent consistent with
its investment objectives.
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of its outstanding voting securities. A "majority of
its outstanding voting securities" means the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented, or (ii) more than 50% of the outstanding shares. In addition, the
Fund has adopted certain investment limitations that also may not be changed
without shareholder approval. A complete description of these limitations is
included in the Statement of Additional Information. Unless specifically noted,
the Fund's investment policies described in this Prospectus and in the Statement
of Additional Information may be changed by the Trust's Board of Trustees
without shareholder approval. The Fund's policies regarding lending, and the
percentage of Fund assets that may be committed to borrowing, are fundamental
policies and may not be changed without shareholder approval.
    
 
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
GENERAL. There is no assurance that the Fund will achieve its investment
objectives. Investing in the Fund entails a substantial degree of risk, and an
investment in the Fund should be considered speculative. Investors are strongly
advised to consider carefully the special risks involved in investing in
emerging markets, which are in addition to the usual risks of investing in
developed markets around the world.
 
   
The Fund's net asset value will fluctuate, reflecting fluctuations in the market
value of its portfolio positions and its net currency exposure. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Fund will fluctuate
in response to general market and economic developments, as well as developments
affecting the particular issuers of such securities.
    
 
In addition, the value of debt securities held by the Fund generally will
fluctuate with the perceived creditworthiness of the issuers of such securities
and interest rates.
 
NON-DIVERSIFIED CLASSIFICATION. The Fund is classified under the 1940 Act as a
"non-diversified" fund. As a result, the Fund will be able to invest in a
smaller number of issuers than if it was classified under the 1940 Act as a
"diversified" fund. To the extent that the Fund invests in a smaller number of
issuers, the net asset value of its shares may fluctuate more widely and it may
be subject to greater investment and credit risk with respect to its portfolio.
 
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of, the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to
 
                               Prospectus Page 12
<PAGE>
                          AIM DEVELOPING MARKETS FUND
domestic companies. In addition, certain costs attributable to foreign
investing, such as custody charges, are higher than those attributable to
domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's net investment income from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing that income.
 
Investing in some foreign countries involves risks relating to potential
political and economic instability within such countries and the risks of
expropriation, nationalization, confiscation of assets and property or the
imposition of restrictions on foreign investment and on repatriation of capital
invested. In the event of such expropriation, nationalization or other
confiscation, the Fund could lose its entire investment in that market.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, currency depreciation,
resource self-sufficiency and balance of payments positions. Investments in
foreign government securities involve special risks, including the risk that the
government issuers may be unable or unwilling to repay principal or interest
when due.
 
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between such currencies and the
U.S. dollar. Changes in currency exchange rates will affect the net asset value
of the Fund's shares and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by it.
 
INVESTING IN EMERGING MARKETS. Emerging markets generally are dependent heavily
upon international trade and, accordingly, have been and may continue to be
affected adversely by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. Inflation and rapid fluctuations in
inflation rates have had and may continue to have negative effects on the
economies and securities markets of certain countries with emerging markets.
 
Disclosure and regulatory standards in many respects are less stringent than in
the United States and other major markets. There also may be a lower level of
monitoring and regulation of emerging markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
 
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Fund to make intended securities purchases due to settlement
problems could cause it to miss attractive investment opportunities. Inability
to dispose of a portfolio security caused by settlement problems could result
either in losses to the Fund due to subsequent declines in value of the
portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.
 
   
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
developed countries. The risk also exists that an emergency situation may arise
in one or more emerging markets as a result of which trading of securities may
cease or may be substantially curtailed and prices for the Fund's portfolio
securities in such markets may not be readily available. Section 22(e) of the
1940 Act permits a registered investment company, such as the Fund, to suspend
redemption of its shares for any period during which an emergency exists, as
determined by the SEC. Accordingly, when the Fund believes that circumstances
dictate, it will promptly apply to the SEC for a determination that such an
emergency exists. During the period commencing with the Fund's identification of
such conditions until the date of any SEC action, the Fund's portfolio
securities in the affected markets will be valued at fair value determined in
good faith by or under the direction of the Trust's Board of Trustees.
    
 
RISKS ASSOCIATED WITH DEBT SECURITIES. The value of the debt securities held by
the Fund generally will vary inversely with market interest rates. If interest
rates in a market fall, the Fund's debt securities issued by governments or
companies in that market ordinarily will increase in value. If market interest
rates increase, however, the debt securities owned by the Fund in that market
will likely decrease in value.

<PAGE>
                          AIM DEVELOPING MARKETS FUND
 
RISKS ASSOCIATED WITH BELOW INVESTMENT GRADE DEBT SECURITIES. The Fund may
invest up to 50% of its total assets in debt securities rated below investment
grade. Such investments involve a high degree of risk.
 
Debt rated Baa by Moody's Investors Service, Inc. ("Moody's") is considered by
Moody's to have speculative characteristics. Debt rated BB, B, CCC, CC or C by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), and
debt rated Ba, B, Caa, Ca or C by Moody's is regarded, on balance, as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. While such
lower quality debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
conditions. Debt rated C by Moody's or S&P is the lowest rated debt that is not
in default as to principal or interest, and issues so rated can be regarded as
having extremely poor prospects of ever attaining any real investment standing.
Lower quality debt securities are also generally considered to be subject to
greater risk than securities with higher ratings with regard to a deterioration
of general economic conditions. These foreign debt securities are the equivalent
of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting it, such as its inability to meet specific
projected business forecasts or the unavailability of additional financing.
Similarly, certain emerging market governments that issue lower quality debt
securities are among the largest debtors to commercial banks, foreign
governments and supranational organizations such as the World Bank and may not
be able or willing to make principal and/or interest repayments as they come
due. The risk of loss due to default by the issuer is significantly greater for
the holders of lower quality securities because such securities are generally
unsecured and may be subordinated to the claims of other creditors of the
issuer.
 
Lower quality debt securities frequently have call or buy-back features that
would permit an issuer to call or repurchase the security from the Fund. In
addition, the Fund may have difficulty disposing of lower quality securities
because they may have a thin trading market. There may be no established retail
secondary market for many of these securities, and the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing its portfolio. The Fund may also acquire lower quality debt securities
during an initial underwriting or that are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
 
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include (1) potential adverse publicity, (2) heightened sensitivity to general
economic or political conditions and (3) the likely adverse impact of a major
economic recession.
 
The Fund may also incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in emerging markets can differ
from debt obligations issued by private entities in that remedies from defaults
generally must be pursued in the courts of the defaulting government, and legal
recourse is therefore somewhat

<PAGE>
                          AIM DEVELOPING MARKETS FUND
diminished. Political conditions, in terms of a government's willingness to meet
the terms of its debt obligations, also are of considerable significance. There
can be no assurance that the holders of commercial bank debt may not contest
payments to the holders of debt securities issued by governments in emerging
markets in the event of default by the governments under commercial bank loan
agreements.
 
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities, and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.
 
CURRENCY RISK. Because the Fund may invest substantially in securities
denominated in currencies other than the U.S. dollar, and since the Fund may
hold foreign currencies, it will be affected favorably or unfavorably by
exchange control regulations or changes in the exchange rates between such
currencies and the U.S. dollar. Changes in currency exchange rates will affect
the net asset value of the Fund's shares and also may affect the value of
dividends and interest earned by the Fund and gains and losses realized by it.
Currencies generally are evaluated on the basis of fundamental economic criteria
(e.g., relative inflation and interest rate levels and trends, growth rate
forecasts, balance of payments status and economic policies) as well as
technical and political data. Exchange rates are determined by the forces of
supply and demand in the foreign exchange markets. These forces are affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. If the
currency in which a security is denominated appreciates against the U.S. dollar,
the dollar value of the security will increase. Conversely, a decline in the
exchange rate of the currency would adversely affect the value of the security
expressed in dollars.
 
Many of the currencies of emerging market countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries. Any devaluations in the currencies
in which the Fund's portfolio securities are denominated may have a detrimental
impact on the Fund.
 
Some countries also may have fixed currencies whose values against the U.S.
dollar are not independently determined. In addition, there is a risk that
certain countries may restrict the free conversion of their currencies into
other currencies. Further, certain currencies may not be internationally traded.
 
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. The Fund is authorized to
enter into options, futures and forward currency transactions. These
transactions involve certain risks, which include: (1) dependence on the
Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets and movements in
interest rates and currency markets; (2) imperfect correlation, or even no
correlation, between movements in the price of forward contracts, options,
futures contracts or options thereon and movements in the price of the currency
or security hedged or used for cover; (3) the fact that skills and techniques
needed to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Fund invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of the Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for the Fund to sell a security at a disadvantageous time, due to
the need for the Fund to maintain "cover" or to set aside securities in
connection with hedging transactions.
 
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may have difficulty disposing of
Assignments and Participations. The liquidity of such securities is limited, and
the Fund anticipates that such securities could be sold only to a limited number
of institutional investors. The lack of a liquid secondary market could have an
adverse impact on the value of such securities and on the Fund's ability to
dispose of particular Assignments or Participations when necessary to meet its
liquidity needs or in response to a specific economic event, such as a
deterioration in the creditworthiness of the borrower. The lack of a liquid
secondary market for Assignments and Participations also may make it more
difficult for the Fund to assign a value to those securities for purposes of
valuing its portfolio and calculating its net asset value.

SOVEREIGN DEBT. The Fund may invest in sovereign debt securities of emerging
market governments, including Brady Bonds. Investments in such securities
involve special risks. The issuer of the debt or the governmental authorities
that control the repayment of the debt may be unable or unwilling to repay
principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn the Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
 
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
 
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's investments.
Emerging markets are faced with social and political issues, and some of them
have experienced high rates of inflation in recent years and have extensive
internal debt. Among other effects, high inflation and internal debt service
requirements may adversely affect the cost and availability of future domestic
sovereign borrowing to finance governmental programs and may have other adverse
social, political and economic consequences. Political changes or a
deterioration of a country's domestic economy or balance of trade may affect its
willingness to service its sovereign debt. Although the Sub-adviser intends to
manage the Fund in a manner that will minimize the exposure to such risks, there
can be no assurance that adverse political changes will not cause the Fund to
suffer a loss of interest or principal on any of its holdings.
 
In recent years, some of the emerging market countries in which the Fund expects
to invest have encountered difficulties in servicing their sovereign debt
obligations. Some of these countries have withheld payments of interest and/or
principal of sovereign debt. These difficulties have also led to agreements to
restructure external debt obligations -- in particular, commercial bank loans --
typically by rescheduling principal payments, reducing interest rates and
extending new credits to finance interest payments on existing debt. In the
future, holders of emerging market sovereign debt securities may be requested to
participate in similar rescheduling of such debt. Certain emerging market
countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by which a creditor may collect in whole or in
part sovereign debt on which an emerging market government has defaulted.
 
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
 
As noted above, sovereign debt obligations issued by emerging market governments
generally are deemed to be the equivalent in terms of quality to securities
rated below investment grade by Moody's and S&P. Such securities are regarded as
 
                               Prospectus Page 16

                          AIM DEVELOPING MARKETS FUND
   
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligations and involve
major risk exposure to adverse conditions. Some of such securities, with respect
to which the issuer currently may not be paying interest or may be in payment
default, may be comparable to securities rated D by S&P or C by Moody's. The
Fund may have difficulty disposing of and valuing certain sovereign debt
obligations because there may be a limited trading market for such securities.
Because there is no liquid secondary market for many of these securities, the
Fund anticipates that such securities could be sold only to a limited number of
dealers or institutional investors.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day-to-day operations of the Fund are delegated to the officers
of the Trust, subject always to the investment objectives and policies of the
Fund and to the general supervision of the Trust's Board of Trustees. See "Board
of Trustees and Executive Officers" in the Statement of Additional Information
for information on the Trust's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include
determining the composition of the Fund's portfolio and placing orders to buy,
sell or hold particular securities; furnishing corporate officers and clerical
staff; providing office space, services and equipment; and supervising all
matters relating to the Fund's operation. For these services, the Fund pays AIM
investment management and administration fees, computed daily and paid monthly,
based on its average daily net assets, at the annualized rate of .975% on the
first $500 million, .95% on the next $500 million, .925% on the next $500
million and .90% on amounts thereafter. Out of the aggregate fees payable by the
Fund, AIM pays the Sub-adviser sub-advisory and sub-administration fees equal to
40% of the aggregate fees AIM receives from the Fund. The investment management
and administration fees paid by the Fund are higher than those paid by most
mutual funds. The Fund pays all expenses not assumed by AIM, the Sub-adviser,
AIM Distributors or other agents. AIM has undertaken to limit the Fund's
expenses (exclusive of brokerage commissions, taxes, interest and extraordinary
expenses) to the annual rate of 2.00% and 2.50% of the average daily net assets
of the Fund's Class A and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administrative services agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization

of the Sub-adviser, consummated a purchase agreement with AMVESCAP PLC pursuant
to which AMVESCAP PLC acquired LGT's Asset Management Division, which included
the Sub-adviser and certain other affiliates. As a result of this transaction,
the Sub-adviser is now an indirect wholly owned subsidiary of AMVESCAP PLC.
Prior to the sale, the Sub-adviser and its worldwide asset management affiliates
provided investment management and/or administrative services to institutional,
corporate and individual clients around the world since 1969.
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser. High portfolio turnover (over
100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund will bear directly and could result in the
realization of net capital gains which would be taxable when distributed to
shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with
    
 
                               Prospectus Page 18

                          AIM DEVELOPING MARKETS FUND
   
whom AIM Distributors has entered into selected dealer agreements. Under the
Distribution Agreement for the Class B shares, AIM Distributors sells Class B
shares of the Fund at net asset value subject to a contingent deferred sales
charge established by AIM Distributors. AIM Distributors is authorized to
advance to institutions through whom Class B shares are sold a sales commission
under schedules established by AIM Distributors. The Distribution Agreement for
the Class B shares provides that AIM Distributors (or its assignee or
transferee) will receive 0.75% (of the total 1.00% payable under the
distribution plan applicable to Class B shares) of the Fund's average daily net
assets attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.

                          AIM DEVELOPING MARKETS FUND
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4 , 1998 the Company acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of thirteen separate and distinct series portfolios of
the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of

the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions. See "All Groups of AIM Funds." PURCHASES OF $1,000,000 OR MORE ARE
AT NET ASSET VALUE, SUBJECT TO A CONTINGENT DEFERRED SALES CHARGE OF 1% IF
SHARES ARE REDEEMED PRIOR TO 18 MONTHS FROM THE DATE SUCH SHARES WERE PURCHASED,
AS DESCRIBED UNDER THE CAPTION "HOW TO REDEEM SHARES -- CONTINGENT DEFERRED

    GROUP III.  Certain AIM Funds are currently sold with a sales charge ranging
from 1.00% to 0.50% of the offering price on purchases of less than $1,000,000.
These AIM Funds are the Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND.

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9

                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,
established for tax-qualified group annuities, for contracts purchased on or
before June 30, 1992. AIM Distributors acts as distributor for the AIM Funds
which represent a range of different investment objectives and policies. As set
forth under the caption "Terms and Conditions of Purchase of the AIM Funds --
Sales Charges and Dealer Concessions," shares of certain of the AIM Funds,
including the Class A shares of the Multiple Class Funds, listed below and
referred to herein as the "Load Funds," are sold at a public offering price that
includes a maximum sales charge of 5.50% or 4.75% of the public offering price
of such shares; Class A shares (or shares which normally involve the payment of
initial sales charges) of certain of the AIM Funds, listed below and referred to
herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain

                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in
    
 
                                      A-23

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE

    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other

taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

                        PROSPECTUS -- SEPTEMBER 8, 1998
    
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Emerging Markets Fund (The
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end, series, management investment
company. The Fund is a diversified portfolio which seeks long-term growth of
capital by investing primarily in equity securities of companies in emerging
markets.
    
   
The Fund is designed for long term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in lower quality and unrated
foreign government bonds whose credit quality is generally considered the
equivalent of U.S. corporate debt securities commonly known as "junk bonds."
Investments of this type are subject to a greater risk of loss of principal and
interest. An investment in the Fund should be considered speculative and subject
to special risk factors, related primarily to the Fund's investments in emerging
markets. Purchasers should carefully assess the risks associated with an
investment in the Fund.
    
 
   
This Prospectus sets forth concisely the information about the Fund that
prospective investors should know before investing. It should be read and
retained for future reference. A Statement of Additional Information dated
September 8, 1998 has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated herein by reference. The Statement of Additional
Information is available without charge upon written request to the Trust at 11
Greenway Plaza, Suite 100, Houston, Texas 77046-1173 or by calling
1-800-347-4246. The SEC maintains a Web site at http://www.sec.gov that contains
the Statement of Additional Information, material incorporated by reference, and
other information regarding the Fund. Additional information about the Fund may

The Fund:                      The Fund is a diversified series of the Trust.
Investment Objective:          The Fund seeks long-term growth of capital.
Principal Investment:          The  Fund normally  invests at least  65% of its  total assets  in equity securities  of companies in
                               emerging markets.
Investment Managers:           The Fund is  managed by  A I  M Advisors, Inc.  ("AIM") and  is sub-advised  and sub-administered  by
                               INVESCO  (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or  administrative services to institutional,  corporate
                               and  individual clients  around the  world. AIM and  the Sub-adviser  are both  indirect wholly owned
                               subsidiaries of AMVESCAP PLC. AMVESCAP  PLC and its subsidiaries  are an independent investment  man-
                               agement  group  that has  a  significant presence  in  the institutional  and  retail segment  of the
                               investment management industry in North America and Europe,  and a growing presence in Asia. AIM  was
                               organized  in 1976 and, together with its subsidiaries, currently advises approximately 90 investment
                               company portfolios.
Purchasing Shares:             Investors may select Class A or Class B shares of the Fund which are offered by this Prospectus at an
                               offering price that reflects differing sales charges and expense levels. See "Terms and Conditions of
                               Purchase of  the AIM/GT  Funds --  Sales  Charges and  Dealer Concessions."  Pursuant to  a  separate
                               prospectus,  the Fund also  offers Advisor Class shares,  which represent interests  in the Fund. The
                               Advisor Class has different distribution arrangements.
  Class A Shares:              Shares are offered at net asset value plus any applicable initial sales charge.

  Class B Shares:              Shares are offered at net asset  value without an initial sales charge  and are subject to a  maximum
                               contingent  deferred sales charge  of 5% on certain  redemptions made within six  years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund  eight
                               years  following the  end of  the calender month  in which  a purchase was  made. Class  B shares are
                               subject to higher expenses than Class A shares.
                               Initial investments in any class of shares must  be at least $500 and additional investments must  be
                               at  least  $50. The  minimum initial  investment  is modified  for investments  through tax-qualified
                               retirement plans  and accounts  initially established  with an  Automatic Investment  Plan. The  dis-
                               tributor  of the  Fund's shares  is A  I M  Distributors, Inc.  ("AIM Distributors"),  P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing  shares
                               that  is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors  should consider whether, during the anticipated  life
                               of  their investment  in the Fund,  the accumulated  distribution fees and  any applicable contingent
                               deferred sales charges on  Class B shares prior  to conversion would be  less than the initial  sales
                               charge  and accumulated distribution fees on  Class A shares purchased at  the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist  investors
                               in  making this determination,  the table under the  caption "Table of Fees  and Expenses" sets forth
                               examples of the charges  applicable to each  class of shares.  Class A shares  will normally be  more
                               beneficial  than Class B shares to  the investor who qualifies for  reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
Exchange Privilege:            The Fund is among those mutual funds  distributed by AIM Distributors (collectively, "The AIM  Family
                               of  Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of  Funds in the  manner and subject  to the policies  and charges set  forth herein.  See
                               "Exchange Privilege."
Redeeming Shares:              Class  A shareholders of the Fund may  redeem all or a portion of  their shares at net asset value on
                               any business day, generally  without charge. A contingent  deferred sales charge of  1% may apply  to
                               certain  redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

                               Class B shareholders of the Fund may  redeem all or a portion of  their shares at net asset value  on
                               any  business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such  shares were purchased.  Class B  shares redeemed after  six years from  the date  such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
Distributions:                 The  Fund currently  declares and pays  dividends from  net investment income,  if any,  on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis.  Dividends
                               and  distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds.  See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
Risk Factors:                  There  is no  assurance that the  Fund will  achieve its investment  objective. The  Fund's net asset
                               values will fluctuate, reflecting fluctuations in the market value of its portfolio holdings.
                               The Fund will invest primarily in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the  Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies  may be less liquid and  their prices more volatile than  those of securities of comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall  level of investment  and currency risk  associated with its  present or  planned
                               investments. Such transactions involve certain risks and transaction costs.
                               The  Fund  may invest  up to  20% of  its  total assets  in below  investment grade  debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

- ------------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charges permitted by the National Association of Securities
    Dealers, Inc. ("NASD") rules regarding investment companies.
    
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 2.00% and 2.50% of the average daily net assets of the Fund's
    Class A and Class B shares, respectively. "Other expenses" include custody,
    transfer agency, legal, audit and other operating expenses. Without
    reimbursements and waivers, "Other expenses" and "Total Fund Operating
    Expenses" would have been 0.70% and 2.18%, respectively, for Class A Shares
    and 0.70% and 2.68%, respectively, for Class B Shares of the Fund. See
    "Management" herein and the Statement of Additional Information for more
    information.
    
   
(4) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the Hypothetical Example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.
    
   
(5) Assumes payment of maximum sales charge by the investor.
    
   
(6) Assumes deduction of the applicable contingent deferred sales charge.
    
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

                              FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.
    
 
                           AIM EMERGING MARKETS FUND
                   (FORMERLY GT GLOBAL EMERGING MARKETS FUND)
   
                                 [TO BE ADDED]
    
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term growth of capital. Under normal
circumstances, the Fund seeks its objective by investing at least 65% of its
total assets in equity securities of companies in emerging markets. The Fund may
invest in the following types of equity securities: common stock, preferred
stock, securities convertible into common stock, rights and warrants to acquire
such securities and substantially similar forms of equity with comparable risk
characteristics. There can be no assurance that the Fund will meet its
investment objectives.
    
   
For purposes of the Fund's operations, "emerging markets" consist of all
countries determined by the Sub-adviser to have developing or emerging economies
and markets. These countries generally include every country in the world except
the United States, Canada, Japan, Australia, New Zealand and most countries
located in Western Europe. See "Investment Objective and Policies" in the
Statement of Additional Information for a complete list of all the countries
that the Fund does not consider to be emerging markets.
    
   
For purposes of the Fund's policy of normally investing at least 65% of its
total assets in equity securities of issuers in emerging markets, the Fund will
consider investment in the following emerging markets:

  Ghana           Panama         Zambia
  Greece          Paraguay       Zimbabwe
</TABLE>
 
   
Although the Fund considers each of the above-listed countries eligible for
investment, it will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements for the Fund's assets, overly
burdensome repatriation and similar restrictions, the lack of organized and
liquid securities markets, unacceptable political risks or for other reasons.
    
 
As used in this Prospectus, an issuer in an emerging market is an entity: (i)
for which the principal securities trading market is an emerging market, as
defined above; (ii) that (alone or on a consolidated basis) derives 50% or more
of its total revenues from business in emerging markets, provided that, in the
Sub-adviser's view, the value of such issuer's securities will tend to reflect
emerging market developments to a greater extent than developments elsewhere; or
(iii) organized under the laws of, or with a principal office in, an emerging
market.
 
   
The Fund may also invest up to 35% of its total assets in (i) debt securities of
government or corporate issuers in emerging markets; (ii) equity and debt
securities of issuers in developed countries, including the United States; (iii)
securities of issuers in emerging markets not included in the list of emerging
markets above, if investing therein becomes feasible and desirable subsequent to
the date of this Prospectus; and (iv) cash and money market instruments.
    
 
   
The Fund invests in those emerging markets that the Sub-adviser believes have
strongly developing economies and in which the markets are becoming more
sophisticated. In selecting investments, the Sub-adviser seeks to identify those
countries and industries where economic and political factors, including
currency movements, are likely to produce above-average growth rates. The
Sub-adviser then invests in those companies in such countries and industries
that are best positioned and managed to take advantage of these economic and
political factors. The Fund ordinarily will be invested in the securities of
issuers in at least three different emerging markets. In evaluating investments
in securities of issuers in developed markets, the Sub-
    
 
                               Prospectus Page 7
<PAGE>
                           AIM EMERGING MARKETS FUND
adviser will consider, among other things, the business activities of the issuer
in emerging markets and the impact that developments in emerging markets are
likely to have on the issuer.
   
The Sub-adviser believes that the issuers of securities in emerging markets
often have sales and earnings growth rates that exceed those in developed
countries and that such growth rates may in turn be reflected in more rapid
share price appreciation. Accordingly, the Sub-adviser believes that the Fund's
policy of investing in equity securities of companies in emerging markets may
enable the Fund to achieve results superior to those produced by mutual funds
with similar objectives that invest solely in equity securities of issuers
domiciled in the United States and/or in other developed markets.
    
   
INVESTMENTS IN DEBT SECURITIES. The Fund may invest in debt securities of
governmental and corporate issuers in emerging markets. Emerging market debt
securities often are rated below investment grade or not rated by U.S. rating
agencies. The Fund may invest up to 20% of its total assets in debt securities
rated below investment grade. Investment in below investment grade debt
securities involves a high degree of risk and can be speculative. These debt
securities are the equivalent of high yield, high risk bonds, commonly known as
"junk bonds." See "Risk Factors -- Risks Associated with Debt Securities."
    
   
If the rating of a debt security held by the Fund drops below a minimum rating
considered acceptable by the Sub-adviser, the Fund will dispose of any such
security as soon as practicable and consistent with the best interests of the
Fund and its shareholders.
    
   
Growth of capital in debt securities may arise as a result of favorable changes
in relative foreign exchange rates, in relative interest rate levels and/ or in
the creditworthiness of issuers. The receipt of income from debt securities
owned by the Fund is incidental to its objective of long-term growth of capital.
    
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic, or
political conditions. Under a defensive strategy, the Fund temporarily may
invest up to 100% of its assets in cash (U.S. dollars, foreign currencies,
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of its investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund employs a
temporary defensive strategy, it will not be invested so as to achieve directly
its investment objective. In addition, pending investment of proceeds from new
sales of Fund shares or to meet ordinary daily cash needs, the Fund temporarily
may hold cash (U.S. dollars, foreign currencies or multinational currency units)
and may invest any portion of its assets in money market instruments. For a
description of money market instruments in which the Fund may invest, see
"Temporary Defensive Strategies" in the "Investment Objectives and Policies"
section of the Statement of Additional Information.
    
 
   
ADDITIONAL INVESTMENT POLICIES
    
 
   
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940 (the "1940
Act"), the Fund generally may invest up to 10% of its total assets in the
aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
    
 
   
Investment in other investment companies may involve the payment of substantial
premiums above the value of such investment companies' portfolio securities and
is subject to limitations under the 1940 Act and market availability. The Fund
does not intend to invest in such investment companies unless, in the judgment
of the Sub-adviser, the potential benefits of such investment justify the
payment of any applicable premium or sales charge. As a shareholder in an
investment company, the Fund would bear its ratable share of that investment
company's expenses, including its advisory and administration fees. At the same
time the Fund would continue to pay its own management fees and other expenses.
AIM and the Sub-adviser will waive their advisory fees to the extent that the
Fund invests in an Affiliated Fund.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other
    
 
                               Prospectus Page 8
<PAGE>
                           AIM EMERGING MARKETS FUND
   
institutional investors. Securities lending allows a Fund to retain ownership of
the securities loaned and, at the same time, enhances the Fund's total return.
At all times a loan is outstanding, the Fund's borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to the value of the borrowed
securities plus any accrued interest or such other collateral as permitted by
the Fund's investment program and regulatory agencies, and as approved by the
Board. The Fund limits its loans of portfolio securities to an aggregate of 30%
of the value of its total assets, measured at the time any such loan is made.
The risks in lending portfolio securities, as with other extensions of secured
credit, consist of possible delays in receiving additional collateral or in
recovery of the loaned securities and possible loss of rights in the collateral
should the borrower fail financially.
    
   
PRIVATIZATIONS. The governments in some emerging markets have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain emerging markets, the ability of foreign entities such
as the Fund to participate in privatizations may be limited by local law, or the
terms on which the Fund may be permitted to participate may be less advantageous
than those afforded local investors. There can be no assurance that governments
in emerging markets will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
   
BORROWING. It is a fundamental policy of the Fund that it may borrow an amount
up to 33 1/3% of its total assets in order to meet redemption requests.
Borrowing may cause greater fluctuation in the value of the Fund's shares than
would be the case if the Fund did not borrow, but also may enable the Fund to
retain favorable securities positions rather than liquidating such positions to
meet redemptions. It is a nonfundamental policy of the Fund that the Fund will
not purchase securities during times when outstanding borrowings represent 5% or
more of the Fund's total assets.
    
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian bank and will mark to market daily such assets.
There is a risk that the securities may not be delivered and that the Fund may
incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment risk normally associated with the
portfolio. These instruments are often referred to as "derivatives," which may
be defined as financial instruments whose performance is derived, at least in
part, from the performance of another asset (such as a security, currency or an
index of securities). The Fund may enter into such instruments up to the full
value of its portfolio assets. See "Risk Factors -- Options, Futures and Foreign
Currency Transactions" herein and "Options, Futures and Currency Strategies" in
the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and

options on such futures contracts to hedge against movements in exchange rates.
   
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most emerging markets, to securities
denominated in such currencies or to securities of issuers domiciled or
principally engaged in business in such emerging markets. To the extent that
such a market does not exist, the Sub-adviser may not be able to effectively
hedge its investment in such markets.
    
   
The Fund may purchase and sell put and call options on securities to hedge
against the risk of fluctuations in the prices of securities held by the Fund or
that the Sub-adviser intends to include in the Fund's portfolio. The Fund also
may purchase and sell put and call options on indices to hedge against overall
fluctuations in the securities markets generally or in a specific market sector.
    
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
adversely affect the Fund's portfolio. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolios against changes in the general level of interest
rates.
    
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations as
fundamental policies which also may not be changed without shareholder approval.
A complete description of these limitations is included in the Statement of
Additional Information. Unless specifically noted, the Fund's investment
policies described in this Prospectus and in the Statement of Additional
Information may be changed by the Trust's Board of Trustees without shareholder
approval. If a percentage restriction on investment or utilization of assets in
an investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. Investing in the Fund entails a substantial degree of risk and an
investment in the Fund should be considered speculative. Investors are strongly
advised to consider carefully the special risks involved in emerging markets,
which are in addition to the usual risks of investing in developed markets
around the world.
    
 
   
The Fund's net asset value will fluctuate, reflecting fluctuations in the market
value of its portfolio positions and its net currency exposure. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Fund will fluctuate
in response to general market and economic developments, as well as developments
affecting the particular issuers of such securities.
    
 
   
Investing in emerging markets involves risks relating to potential political and
economic instability
    
 
                               Prospectus Page 10
<PAGE>
                           AIM EMERGING MARKETS FUND
   
within such markets and the risks of expropriation, nationalization,
confiscation of assets and property or the imposition of restrictions on foreign
investment and on repatriation of capital invested. In the event of such
expropriation, nationalization or other confiscation, the Fund could lose its
entire investment in that market.
    
Economies in individual emerging markets may differ favorably or unfavorably
from the U.S. economy in such respects as growth of gross domestic product,
rates of inflation, currency depreciation, capital reinvestment, resource self-
sufficiency and balance of payments positions. Many emerging market countries
have experienced high rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain countries with
emerging markets.
Emerging markets generally are dependent heavily upon international trade and,
accordingly, have been and may continue to be affected adversely by trade
barriers, exchange controls, managed adjustments in relative currency values and
other protectionist measures imposed or negotiated by the countries with which
they trade.
   
Disclosure and regulatory standards in many respects are less stringent than in
the U.S. and other major markets. There also may be a lower level of monitoring
and regulation of emerging markets and the activities of investors in such
markets, and enforcement of existing regulations has been extremely limited. In
addition, the securities of non-U.S. issuers generally are not registered with
the SEC, nor are the issuers thereof usually subject to the SEC's reporting
requirements. Accordingly, there may be less publicly available information
about foreign securities and issuers than is available with respect to U.S.
securities and issuers. Foreign companies generally are not subject to uniform
accounting, auditing and financial reporting standards, practices and
requirements comparable to those applicable to U.S. companies. The Fund's net
investment income and/or capital gains from its foreign investment activities
may be subject to non-U.S. withholding taxes.
    
   
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Fund to make intended securities purchases due to settlement
problems could cause the Fund to miss attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems could
result either in losses to the Fund due to subsequent declines in value of the
portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.
    
 
   
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
developed countries. The risk also exists that an emergency situation may arise
in one or more emerging markets as a result of which trading of securities may
cease or may be substantially curtailed and prices for the Fund's portfolio
securities in such markets may not be readily available. Section 22(e) of the
1940 Act permits a registered investment company, such as the Fund, to suspend
redemption of its shares for any period during which an emergency exists, as
determined by the SEC. Accordingly, when the Fund believes that circumstances
dictate, it will promptly apply to the SEC for a determination that such an
emergency exists within the meaning of Section 22(e) of the 1940 Act. During the
period commencing from the Fund's identification of such conditions until the
date of any SEC action, the Fund's portfolio securities in the affected markets
will be valued at fair value determined in good faith by or under the direction
of the Trust's Board of Trustees.
    
 
   
RISKS ASSOCIATED WITH DEBT SECURITIES. The value of the debt securities held by
the Fund generally will vary inversely with market interest rates. If interest
rates in a market fall, the Fund's debt securities issued by governments or
companies in that market ordinarily will increase in value. If market interest
rates increase, however, the debt securities owned by the Fund in that market
will likely decrease in value.
    
 
   
The Fund may invest up to 20% of its total assets in debt securities rated below
investment grade. Such investments involve a high degree of risk.
    
 
Debt rated Baa by Moody's Investors Service, Inc. ("Moody's") is considered by
Moody's to have speculative characteristics. Debt rated BB, B, CCC, CC or C by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), and
debt rated Ba, B, Caa, Ca or C by Moody's is
 
                               Prospectus Page 11
<PAGE>
                           AIM EMERGING MARKETS FUND
regarded, on balance, as predominantly speculative with respect to the issuer's
capacity to pay interest and repay principal in accordance with the terms of the
obligation. While such lower quality debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions. Debt rated C by Moody's or S&P is the
lowest rated debt that is not in default as to principal or interest and such
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing. Lower quality debt securities are also
generally considered to be subject to greater risk than securities with higher
ratings with regard to a deterioration of general economic conditions. These
foreign debt securities are the equivalent of high yield, high risk bonds,
commonly known as "junk bonds."
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. Similarly, certain emerging market governments that issue lower
quality debt securities are among the largest debtors to commercial banks,
foreign governments and supranational organizations such as the World Bank, and
may not be able or willing to make principal and/or interest repayments as they
come due. The risk of loss due to default by the issuer is significantly greater
for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities frequently have call or buy-back features which
would permit an issuer to call or repurchase the security from the Fund. In
addition, the Fund may have difficulty disposing of lower quality securities
because they may have a thin trading market. There may be no established retail
secondary market for many of these securities, and the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing the Fund's portfolio. The Fund may also acquire lower quality debt
securities during an initial underwriting or which are sold without registration
under applicable securities laws. Such securities involve special considerations
and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession.
    
 
   
The Fund may also incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in emerging markets can differ
from debt obligations issued by private entities in that remedies from defaults
generally must be pursued in the courts of the defaulting government, and legal
recourse is therefore somewhat diminished. Political conditions, in terms of a
government's willingness to meet the terms of its debt obligations, also are of
considerable significance. There can be no assurance that the holders of
commercial bank debt may not contest payments to the holders of debt securities
issued by governments in emerging markets in the event of default by the
governments under commercial bank loan agreements.

<PAGE>
                           AIM EMERGING MARKETS FUND
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "Illiquid
Securities."
    
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
   
CURRENCY RISK. Because the Fund may invest substantially in securities
denominated in currencies other than the U.S. dollar, and since the Fund may
hold foreign currencies, the Fund will be affected favorably or unfavorably by
exchange control regulations or changes in the exchange rates between such
currencies and the U.S. dollar. Changes in currency exchange rates will
influence the value of the Fund's shares, and also may affect the value of
dividends and interest earned by the Fund and gains and losses realized by the
Fund. Currencies generally are evaluated on the basis of fundamental economic
criteria (e.g., relative inflation and interest rate levels and trends, growth
rate forecasts, balance of payments status and economic policies) as well as
technical and political data. Exchange rates are determined by the forces of
supply and demand in the foreign exchange markets. These forces are affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. If the
currency in which a security is denominated appreciates against the U.S. dollar,
the dollar value of the security will increase. Conversely, a decline in the
exchange rate of the currency would adversely affect the value of the security
expressed in dollars.
    
   
Many of the currencies of emerging market countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries. Any devaluations in the currencies
in which the Fund's portfolio securities are denominated may have a detrimental
impact on the Fund.
    
Some countries also may have fixed currencies whose values against the U.S.
dollar are not independently determined. In addition, there is a risk that
certain countries may restrict the free conversion of their currencies into
other currencies. Further, certain currencies may not be internationally traded.
   
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets and movements in
interest rates and currency markets; (2) imperfect correlation, or even no
correlation, between movements in the price of forward contracts, options,
futures contracts or options thereon and movements in the price of the currency
or security hedged or used for cover; (3) the fact that skills and techniques
needed to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Fund invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of the Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for the Fund to sell a security at a disadvantageous time, due to
the need for the Fund to maintain "cover" or to set aside securities in
connection with hedging transactions.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with

AIM, the investment sub-advisory and sub-administration agreement between AIM
and the Sub-adviser, the agreements with AIM Distributors regarding distribution
of the Fund's shares, the custody agreement and the transfer agency agreement.
The day to day operations of the Fund are delegated to the officers of the
Trust, subject always to the objective and policies of the Fund and to the
general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's Board of Trustees.
    
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the Fund's portfolio and
placing orders to buy, sell or hold particular securities; furnishing corporate
officers and clerical staff; providing office space, services and equipment; and
supervising all matters relating to the Fund's operation. For these services,
the Fund pays AIM investment management and administration fees, computed daily
and paid monthly, based on its average daily net assets, at the annualized rate
of .975% on the first $500 million, .95% on the next $500 million, .925% on the
next $500 million, and .90% on amounts thereafter. Out of the aggregate fees
payable by the Fund, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit each Fund's expenses (exclusive of brokerage commissions,
taxes, interest and extraordinary expenses) to the annual rate of 2.00% and
2.50% of the average daily net assets of the Fund's Class A and Class B shares,
respectively.
    
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly-owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser. High portfolio turnover (over
100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund will bear directly and could result in the
realization of net capital gains which would be taxable when distributed to
shareholders. See "Dividends, Distributions and Tax Matters."
    
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998, on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own
    
 
                               Prospectus Page 15
<PAGE>
                           AIM EMERGING MARKETS FUND
   
Class A shares of the Fund. Payments can also be directed by AIM Distributors to
selected institutions who have entered into service agreements with respect to
Class A shares of the Fund and who provide continuing personal services to their
customers who own Class A shares of the Fund. The service fees payable to
selected institutions are calculated at the annual rate of 0.25% of the average
daily net asset value of those Fund shares that are held in such institution's
customers' accounts which were purchased on or after a prescribed date set forth
in the Plan.
    
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the fund with other shares of the Fund and is
entitled to such other shares of the Fund and is entitled to such dividends and
distributions out of the income earned and gain realized on the assets belonging
to the Fund as may be declared by the Board of Trustees. Each share of the Fund
is equal in earnings, assets and voting privileges except that each class
normally has exclusive voting rights with respect to its distribution plan and
bears the expenses, if any, related to the distribution of its shares. Shares of
the Fund, when issued, are fully paid and nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions. See "All Groups of AIM Funds." PURCHASES OF $1,000,000 OR MORE ARE
AT NET ASSET VALUE, SUBJECT TO A CONTINGENT DEFERRED SALES CHARGE OF 1% IF
SHARES ARE REDEEMED PRIOR TO 18 MONTHS FROM THE DATE SUCH SHARES WERE PURCHASED,
AS DESCRIBED UNDER THE CAPTION "HOW TO REDEEM SHARES -- CONTINGENT DEFERRED

    GROUP III.  Certain AIM Funds are currently sold with a sales charge ranging
from 1.00% to 0.50% of the offering price on purchases of less than $1,000,000.
These AIM Funds are the Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND.

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9

                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10

                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,
established for tax-qualified group annuities, for contracts purchased on or
before June 30, 1992. AIM Distributors acts as distributor for the AIM Funds
which represent a range of different investment objectives and policies. As set
forth under the caption "Terms and Conditions of Purchase of the AIM Funds --
Sales Charges and Dealer Concessions," shares of certain of the AIM Funds,
including the Class A shares of the Multiple Class Funds, listed below and
referred to herein as the "Load Funds," are sold at a public offering price that
includes a maximum sales charge of 5.50% or 4.75% of the public offering price
of such shares; Class A shares (or shares which normally involve the payment of
initial sales charges) of certain of the AIM Funds, listed below and referred to
herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain

                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but
 
                                      A-21

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other

taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

                               equity  securities of companies throughout  the world that manufacture,  market, retail or distribute
                               consumer products and services.
 
Investment Managers:           The Portfolio is managed by  AIM Advisors, Inc. ("AIM"), and  is sub-advised and sub-administered  by
                               INVESCO  (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management

Purchasing Shares:             Investors may select Class A or Class B shares of the Fund which are offered by this Prospectus at an
                               offering price that reflects differing sales charges and expense levels. See "Terms and Conditions of
                               Purchase  of  the  AIM  Funds --  Sales  Charges  and  Dealer Concessions."  Pursuant  to  a separate
                               prospectus, the Fund also  offers Advisor Class  shares, which represent interests  in the Fund.  The
                               Advisor Class has different distribution arrangements.
 
  Class A Shares:              Shares are offered at net asset value plus any applicable initial sales charge.
 
  Class B Shares:              Shares  are offered at net asset value without an  initial sales charge, and are subject to a maximum
                               contingent deferred sales charge  of 5% on certain  redemptions made within six  years from the  date
                               such  shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the  end of  the calendar month  in which  a purchase was  made. Class  B shares  are
                               subject to higher expenses than Class A shares.
 
                               Initial  investments in any class of shares must be  at least $500 and additional investments must be
                               at least  $50. The  minimum initial  investment  is modified  for investments  through  tax-qualified
                               retirement  plans and  accounts initially  established with  an Automatic  Investment Plan.  The dis-
                               tributor of the  Fund's shares  is A  I M  Distributors, Inc.  ("AIM Distributors"),  P.O. Box  4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors:     An  investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are  expected
                               to  be held, and other circumstances. Investors  should consider whether, during the anticipated life
                               of their investment  in the Fund,  the accumulated  distribution fees and  any applicable  contingent
                               deferred  sales charges on Class  B shares prior to  conversion would be less  than the initial sales
                               charge and accumulated distribution fees on  Class A shares purchased at  the same time, and to  what
                               extent  such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination,  the table under the  caption "Table of Fees  and Expenses" sets  forth
                               examples  of the charges  applicable to each  class of shares.  Class A shares  will normally be more
                               beneficial than Class B shares  to the investor who qualifies  for reduced initial sales charges,  as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The  Fund is among those mutual funds distributed  by AIM Distributors (collectively, "The AIM Family
                               of Funds"), Class A and Class B shares of the Fund may be exchanged for shares of other funds in  The
                               AIM  Family of  Funds in the  manner and subject  to the policies  and charges set  forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may  redeem all or a portion of  their shares at net asset value  on
                               any  business day, generally  without charge. A contingent  deferred sales charge of  1% may apply to
                               certain redemptions  where a  purchase of  more than  $1  million is  made at  net asset  value.  See

                               Class  B shareholders of the Fund may  redeem all or a portion of  their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years  from
                               the  date such  shares were purchased.  Class B shares  redeemed after  six years from  the date such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently  declares and  pays dividends from  net investment  income, if any,  on an  annual
                               basis.  The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales  charge
                               in  the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no  assurance that  the Fund or  the Portfolio  will achieve its  investment objective.  The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the Portfolio's
                               portfolio  holdings. The  Portfolio's policy  of concentrating  its investments  in companies  in the
                               consumer products and services industries may cause the Fund's net asset value to fluctuate more than
                               if it invested in a greater number of industries.
 
                               The Portfolio  may invest  in foreign  securities. Investments  in foreign  securities involve  risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably  from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid  and their prices more volatile  than those of securities of  comparable
                               U.S. companies.
 
                               The  Portfolio may engage in certain foreign currency, options and futures transactions to attempt to
                               hedge against  the overall  level of  investment and  currency risk  associated with  its present  or
                               planned investments. Such transactions involve certain risks and transaction costs.
 
                               The  Portfolio may invest up  to 20% of its  total assets in below  investment grade debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

- ------------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 2.00% and 2.50% of the average daily net assets of the Fund's
    Class A and Class B shares, respectively. "Other expenses" include custody,
    transfer agency, legal, audit and other operating expenses. See "Management"
    herein and the Statement of Additional Information for more information.
    
 
   
    The Board of Trustees of the Trust believes that the aggregate per share
    expenses of the Fund and the Portfolio will be approximately equal to the
    expenses the Fund would incur if its assets were invested directly in the
    type of securities being held by the Portfolio.
    
 
   
(4) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds. The 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.
    
 
   
(5) Assumes payment of maximum sales charge by the investor.
    
 
   
(6) Assumes deduction of the applicable contingent deferred sales charge.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.
    
 
   
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
            (FORMERLY GT GLOBAL CONSUMER PRODUCTS AND SERVICES FUND)

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all of a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
 
   
                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that manufacture, market, retail or distribute consumer products and services.
The Portfolio's investment objective is identical to that of the Fund. There can
be no assurance that the Fund or Portfolio will achieve its investment
objective.
    
 
   
At least 65% of the Portfolio's total assets normally will be invested in common
and preferred stocks and warrants to acquire such securities issued by consumer
products and services companies. A "consumer products or services" company is an
entity in which (i) at least 50% of either the revenues or earnings was derived
from activities relating to consumer products or services, or (ii) at least 50%
of the assets was devoted to such activities, based on the company's most recent
fiscal year. The remainder of the Portfolio's assets may be invested in debt
securities issued by consumer products or services companies and/or equity and
debt securities of companies outside the consumer products or services
industries, which, in the opinion of the Sub-adviser, stand to benefit from
developments in such industries.
    
 
GLOBAL CONSUMER PRODUCTS AND SERVICES INDUSTRIES INVESTMENT. Examples of
consumer products and services companies include those that manufacture, market,
retail, or distribute: durable goods (such as homes, household goods,
automobiles, boats, furniture and appliances, and computers); non-durable goods
(such as food and beverages and apparel); media, entertainment, broadcasting,
publishing and sports-related goods and services (such as television and radio
broadcast, motion pictures, wireless communications, gaming casinos, theme
parks, restaurants and lodging); and goods and services to companies in the
foregoing industries (such as advertisers, textile companies and distribution
and shipping companies).
 
   
The Portfolio expects that a significant portion of its assets may be invested
in the securities of U.S. issuers from time to time, particularly those that
market their products globally. However, consumer products and services
companies of a particular nation or region of the world are often operated and
owned in their local markets, close to their customers. These companies, the
Sub-adviser believes, may offer superior opportunities for capital growth as
compared to their larger, multinational counterparts. Certain global markets may
be more attractive than others from time to time; companies dependent on U.S.
markets, for example, may be outperformed by companies not dependent on U.S.
markets.
    
 
   
The Sub-adviser also believes that the demand for consumer products and services
worldwide will increase along with rising disposable incomes in both developed
and developing nations. Emerging economies, such as those in China, Southeast
Asia, Eastern Europe and Latin America, offer opportunities for the growth and
expansion of consumer markets. These regions currently comprise a growing source
of inexpensive consumer products for export and a growing source of demand for
consumer products and services as the disposable incomes of their populations
increase. In the Sub-adviser's view, these changes are likely to create
investment opportunities in companies, both local and multinational, that are
able to employ innovative manufacturing, marketing, retailing and distribution
methods to open new markets and/or expand existing markets.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the
consumer products and services industries are headquartered outside of the
United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets located throughout the world and the substantial global
resources of AMVESCAP PLC in attempting to identify those countries and
companies then providing the greatest potential for long-term
    
 
                               Prospectus Page 7
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
capital appreciation. In this fashion, the Sub-adviser seeks to enable
shareholders to capitalize on the substantial investment opportunities and the
potential for long-term growth of capital presented by the global consumer
products and services industries represented in the Portfolio.
    
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 50% of the Portfolio's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank
    
 
                               Prospectus Page 8
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
or broker/dealer, in return for cash, and agrees to repurchase the security in
the future at an agreed upon price which includes an interest component. A
"roll" borrowing transaction involves the Portfolio's sale of securities
together with its commitment (for which the Portfolio may receive a fee) to
purchase similar, but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolios to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other collateral as permitted by the Portfolio's investment program and
regulatory agencies, and as approved by the Board. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Portfolio's holdings. The Portfolio also may

<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
purchase stock index futures contracts and purchase call options or write put
options on such contracts to hedge against a general stock market or market
sector advance and thereby attempt to lessen the cost of future securities
acquisitions. The Portfolio may use interest rate futures contracts and options
thereon to hedge the debt portion of its portfolio against changes in the
general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of that Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval. The investment policies of the Fund are identical to the
investment policies of the Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in its corresponding
Portfolio's investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts," respectively, in the
Investment Objectives and Policies section of the Statement of Additional
Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because a Fund will invest only in its corresponding Portfolio, the Fund's
shareholders will acquire only an indirect interest in the investments of that
Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in a Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may experience

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
different returns than investors in another investment company that invests
exclusively in the Portfolio. As of the date of this Prospectus, the Fund is the
only institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the consumer products and
services industries, an investment in it may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
Moreover, the value of the shares of the Fund will be especially susceptible to
factors affecting the consumer products and services industries. Accordingly,
the Fund should not be considered a complete investment program.
    
 
   
CONSUMER PRODUCTS AND SERVICES INDUSTRIES. The performance of consumer products
and services companies, relates closely to the actual or perceived performance
of the overall economy, interest rates and consumer confidence. In addition,
changes in demographics and consumer tastes may also affect the demand for, and
success of, particular consumer products and services. Many consumer products
and services companies have unpredictable earnings, due in part to changes in
consumer tastes and intense competition. As a result, such companies may be
subject to increased share price volatility. The consumer products and services
industries may also be subject to greater government regulation, including trade
regulation, than many other industries. Changes in governmental policy and the
need for regulatory approvals may have a material effect on the products and
services offered by companies in the consumer products and services industries.
Such governmental regulations may also hamper the development of new business
opportunities.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Portfolio's interest and dividends from foreign issuers may be
subject to non-U.S. withholding taxes, thereby reducing the Portfolio's net
investment income.
    
 
                               Prospectus Page 11
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 20%, of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of
 
                               Prospectus Page 12
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
additional financing. The risk of loss due to default by the issuer is
significantly greater for the holders of lower quality securities because such
securities are generally unsecured and may be subordinated to the claims of
other creditors of the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if it did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the Portfolio to sell a security at a disadvantageous time, due to the need for
the Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
a result, the prices of the securities of such smaller companies may fluctuate
to a greater degree than the prices of the securities of other issuers.

                                   MANAGEMENT
    
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the investment objective and policies of the Fund
and the Portfolio and to the general supervision of the Boards. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers and administrators to the Fund and the
Portfolio include, but are not limited to, determining the composition of the
investment holdings of the Portfolio and placing orders to buy, sell or hold
particular securities. In addition, AIM and the Sub-adviser provide the
following administration services to the Portfolio and the Fund: furnishing
corporate officers and clerical staff; providing office space, services and
equipment; and supervising all matters relating to the Portfolio's and the
Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by its corresponding
Portfolio to AIM and the Sub-adviser. The Portfolio pays AIM a fee, based on the
Portfolio's average daily net assets at the annualized rate of .725% on the
first $500 million, .70% on the next $500 million, .675% on the next $500
million and .65% on all amounts thereafter. Out of its aggregate fees payable by
the Fund and the Portfolio, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund and the Portfolio. The investment management and administration fees paid
by the Fund and the Portfolio are higher than those paid by most mutual funds.
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 2.00% and 2.50% of the average daily net assets of the Fund's Class A
and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
PLC acquired LGT's Asset Management Division, which included the Sub-adviser and
certain other affiliates. As a result of this transaction, the Sub-adviser is
now an indirect wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the
Sub-adviser and its worldwide asset management affiliates provided investment
management and/or administrative services to institutional, corporate and
individual clients around the world since 1969.
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
   
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.

DISTRIBUTION PLANS. CLASS A PLAN.  The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may continue to establish other
funds, each corresponding to a distinct investment portfolio and a distinct
series of the Trust's shares of beneficial interest. Shares of each fund are
entitled to one vote per share (with proportional voting for fractional shares)
and are freely transferable. Shareholders have no preemptive rights. Other than
the automatic conversion of Class B shares to Class A shares, there are no
conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other shares do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the
    
 
                               Prospectus Page 17
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
   
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without
a sales charge and Class B shares (the "Class B shares") and Class C shares (the

applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For

applicable to a purchase of shares of a fund may be reduced if certain

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9
<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,
established for tax-qualified group annuities, for contracts purchased on or
before June 30, 1992. AIM Distributors acts as distributor for the AIM Funds
which represent a range of different investment objectives and policies. As set
forth under the caption "Terms and Conditions of Purchase of the AIM Funds --
Sales Charges and Dealer Concessions," shares of certain of the AIM Funds,
including the Class A shares of the Multiple Class Funds, listed below and
referred to herein as the "Load Funds," are sold at a public offering price that
includes a maximum sales charge of 5.50% or 4.75% of the public offering price
of such shares; Class A shares (or shares which normally involve the payment of
initial sales charges) of certain of the AIM Funds, listed below and referred to
herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19

                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24

                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other

taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

The Fund and the Portfolio:    The  Fund is  a diversified  series of  the Trust. The  Portfolio is  a diversified  series of Global
                               Investment Portfolio.

Principal Investments:         The Fund invests all of its investable assets in the Portfolio, which, in turn, invests primarily  in
                               equity  securities  of  companies  throughout  the  world  that  operate  in  the  financial services
                               industries.
Investment Managers:           The Portfolio is managed by A I M  Advisors, Inc. ("AIM") and is sub-advised and sub-administered  by
                               INVESCO  (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or  administrative services to institutional,  corporate
                               and  individual clients  around the  world. AIM and  the Sub-adviser  are both  indirect wholly owned

  Class B Shares:              Shares are offered at net asset value without an  initial sales charge, and are subject to a  maximum
                               contingent  deferred sales charge  of 5% on certain  redemptions made within six  years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund  eight
                               years  following the  end of  the calendar month  in which  a purchase was  made. Class  B shares are
                               subject to higher expenses than Class A shares.
                               Initial investments in any class of shares must  be at least $500 and additional investments must  be
                               at  least  $50. The  minimum initial  investment  is modified  for investments  through tax-qualified
                               retirement plans  and accounts  initially established  with an  Automatic Investment  Plan. The  dis-
                               tributor  of the  Fund's shares  is A  I M  Distributors, Inc.  ("AIM Distributors"),  P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing  shares
                               that  is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors  should consider whether, during the anticipated  life
                               of  their investment  in the Fund,  the accumulated  distribution fees and  any applicable contingent
                               deferred sales charges on  Class B shares prior  to conversion would be  less than the initial  sales
                               charge  and accumulated distribution fees on  Class A shares purchased at  the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist  investors
                               in  making this determination,  the table under the  caption "Table of Fees  and Expenses" sets forth
                               examples of the charges  applicable to each  class of shares.  Class A shares  will normally be  more
                               beneficial  than Class B shares to  the investor who qualifies for  reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
Exchange Privilege:            The Fund is among those mutual funds  distributed by AIM Distributors (collectively, "The AIM  Family
                               of  Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of  Funds in the  manner and subject  to the policies  and charges set  forth herein.  See
                               "Exchange Privilege."
Redeeming Shares:              Class  A shareholders of the Fund may  redeem all or a portion of  their shares at net asset value on
                               any business day, generally  without charge. A contingent  deferred sales charge of  1% may apply  to
                               certain  redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

                               any  business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such  shares were purchased.  Class B  shares redeemed after  six years from  the date  such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
Distributions:                 The  Fund currently  declares and pays  dividends from  net investment income,  if any,  on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis.  Dividends
                               and  distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds.  See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
Risk Factors:                  There  is no  assurance that the  Fund or  the Portfolio will  achieve its  investment objective. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the Portfolio's
                               portfolio holdings.  The Portfolio's  policy of  concentrating its  investments in  companies in  the
                               financial  services industries  may cause the  Fund's net  asset value to  fluctuate more  than if it
                               invested in a greater number of industries.
                               The Portfolio  may invest  in foreign  securities. Investments  in foreign  securities involve  risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably  from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid  and their prices more volatile  than those of securities of  comparable
                               U.S. companies.
                               The  Portfolio may engage in certain foreign currency, options and futures transactions to attempt to
                               hedge against  the overall  level of  investment and  currency risk  associated with  its present  or
                               planned investments. Such transactions involve certain risks and transaction costs.
                               The  Portfolio may invest  up to 5%  of its total  assets in below  investment grade debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.
                               See "Investment Objective and Policies" and "Risk Factors."

</TABLE>
    
 
- --------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 2.00% and 2.50% of the average daily net assets of the Fund's
    Class A and Class B shares, respectively. Without reimbursements and
    waivers, "Other Expenses" and "Total Fund Operating Expenses" would have
    been 0.88% and 2.36%, respectively, for Class A shares and 0.88% and 2.86%,
    respectively, for Class B shares of the Fund. "Other expenses" include
    custody, transfer agency, legal, audit and other operating expenses. See
    "Management" herein and the Statement of Additional Information for more
    information.
    
 
   
    The Board of Trustees of the Trust believes that the aggregate per share
    expenses of the Fund and the Portfolio will be approximately equal to the
    expenses the Fund would incur if its assets were invested directly in the
    type of securities being held by the Portfolio.
    
 
   
(4) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds. The 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.
    
 
   
(5) Assumes payment of maximum sales charge by the investor.
    
 
   
(6) Assumes deduction of the applicable contingent deferred sales charge.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.
    
 
                       AIM GLOBAL FINANCIAL SERVICES FUND
                  (FORMERLY GT GLOBAL FINANCIAL SERVICES FUND)
 
   
                                 [TO BE ADDED]
    
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that operate in the financial services industries. The Portfolio's investment
objective is identical to that of the Fund. There can be no assurance that the
Fund or Portfolio will achieve its investment objective.
    
 
   
At least 65% of the Portfolio's total assets normally will be invested in common
and preferred stocks and warrants to acquire such securities issued by financial
services companies. A "financial services" company is an entity in which (i) at
least 50% of either the revenues or earnings was derived from financial services
activities, or (ii) at least 50% of the assets was devoted to such activities,
based on the company's most recent fiscal year. The remainder of the Portfolio's
assets may be invested in debt securities issued by financial services companies
and/or equity and debt securities of companies outside of the financial services
industries, which, in the opinion of the Sub-adviser, stand to benefit from
developments in the financial services industries.
    
 
GLOBAL FINANCIAL SERVICES INDUSTRIES INVESTMENT. Examples of financial services
companies include commercial banks and savings institutions and loan
associations and their holding companies; consumer and industrial finance
companies; diversified financial services companies; investment banks; insurance
brokerages; securities brokerage and investment advisory companies; real estate-
related companies; leasing companies; and a variety of firms in all segments of
the insurance field such as multi-line, property and casualty and life insurance
and insurance holding companies.
 
   
The Sub-adviser believes an accelerating rate of global economic interdependence
will lead to significant growth in the demand for financial services. In
addition, in the Sub-adviser's view, as the industries evolve, opportunities
will emerge for those companies positioned for the future. Thus, the Sub-adviser
expects that banking and related financial institution consolidation in the
developed countries, increased demand for retail borrowing in developing
countries, a growing need for international trade-based financing, a rising
demand for sophisticated risk management, the proliferating number of liquid
securities markets around the world, and larger concentrations of investable
assets should lead to growth in financial service companies that are positioned
for the future.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the
financial services industries are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets located throughout the world and the substantial global
resources of AMVESCAP PLC in attempting to identify those countries and
companies then providing the greatest potential for long-term capital
appreciation. In this fashion, the Sub-adviser seeks to enable shareholders to
capitalize on the substantial investment opportunities and the potential for
long-term growth of capital presented by the global financial services
industries represented in the Portfolio.
    
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 40% of the Portfolio's total assets.
    
 
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average
 
                               Prospectus Page 7

                       AIM GLOBAL FINANCIAL SERVICES FUND
   
per share earnings growth; high return on invested capital; a healthy balance
sheet; sound financial and accounting policies and overall financial strength;
strong competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Portfolio's sale of securities together with
its commitment (for which the Portfolio may receive a fee) to purchase similar,
but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolio to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other

<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
collateral as permitted by the Portfolio's investment program and regulatory
agencies, and as approved by the Board. The risks in lending portfolio
securities, as with other extensions of secured credit, consist of possible
delays in receiving additional collateral or in recovery of the securities and
possible loss of rights in the collateral should the borrower fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Portfolio's holdings. The Portfolio also may purchase stock
index futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The
Portfolio may use interest rate futures contracts and options thereon to hedge
the debt portion of its portfolio against changes in the general level of
interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of

                       AIM GLOBAL FINANCIAL SERVICES FUND
   
Additional Information. Unless specifically noted, the Fund's investment
policies described in this Prospectus and in the Statement of Additional
Information may be changed by the Trust's Board of Trustees without shareholder
approval. The Fund's policies regarding concentration and lending, and the
percentage of the Fund's assets that may be committed to borrowing, are
fundamental policies and may not be changed without shareholder approval. The
investment policies of the Fund are identical to the investment policies of the
Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because the Fund will invest only in the Portfolio, the Fund's shareholders will
acquire only an indirect interest in the investments of the Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may experience different
returns than investors in another investment company that invests exclusively in
the Portfolio. As of the date of this Prospectus, the Fund is the only
institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities positions. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the financial services
industries, an investment in it may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
Moreover, the value of the shares of the Fund will be especially susceptible to
factors affecting the financial services industries. Accordingly, the Fund
should not be considered a complete investment program.
    
 
   
FINANCIAL SERVICES INDUSTRIES. Financial services industries may be subject to
greater governmental regulation than many other industries and changes in
governmental policies and the need for regulatory approvals may have a material
effect on the services offered by companies in the financial services
industries. Governmental regulation may limit both the financial commitments
banks can make, including the amounts and types of loans, and the interest rates
and fees they can charge. In addition, governmental regulation in certain
foreign countries may impose interest rate controls, credit controls and price
controls.
    
 
Companies in the financial services sector are subject to rapid business
changes, significant competition, value fluctuations due to the concentration of
loans in particular industries significantly affected by economic conditions
(such as real estate or energy) and volatile performance dependent upon the
availability and cost of capital and prevailing interest rates. In addition,
general economic conditions significantly affect these companies. Credit and
other losses resulting from the financial difficulty of borrowers or other third
parties potentially may have an adverse effect on companies in these industries.
Foreign banks, particularly those of Japan, have reported financial difficulties
attributed to increased competition, regulatory changes, and general economic
difficulties.
 
The financial services area in the United States currently is changing
relatively rapidly as existing distinctions between various financial service
segments become less clear. For instance, recent business combinations have
included insurance, finance, and securities brokerage under single ownership.
Some primarily retail corporations have expanded into securities and insurance
fields. Investment banking, securities brokerage and investment advisory
companies are subject to government regulation and risk due to securities
trading and underwriting activities.
 
Many of the investment considerations discussed in connection with banks,
savings institutions and loan associations, and finance companies also apply to
insurance companies. The performance of insurance company investments will be
subject to risk from several factors. The earnings of insurance companies will
be affected by interest rates, pricing (including severe pricing competition
from time to time), claims activity, marketing competition and general economic
conditions. Particular insurance lines also will be influenced by specific
matters. Property and casualty insurer profits may be affected by certain
weather catastrophes and other disasters. Life and health insurer profits may be
affected by mortality and morbidity rates. Individual companies may be exposed
to material risks, including reserve inadequacy, problems in investment
portfolios (due to real estate or "junk" bond holdings, for example), and the
inability to collect from reinsurance carriers. Insurance companies are subject
to extensive governmental regulation, including the imposition of maximum rate
levels, which may not be adequate for
some lines of business. Proposed or potential
anti-trust or tax law changes also may affect
 
                               Prospectus Page 11
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
adversely insurance companies' policy sales, tax obligations and profitability.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Portfolio's interest and dividends from foreign issuers may be
subject to non-U.S. withholding taxes, thereby reducing the Portfolio's net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 5% of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
 
                               Prospectus Page 12
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if it did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to
    
 
                               Prospectus Page 13
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
use forward currency contracts are different from those needed to select the
securities in which the Portfolio invests; (4) lack of assurance that a liquid
secondary market will exist for any particular option, futures contract or
option thereon at any particular time; (5) the possible loss of principal under
certain conditions; and (6) the possible inability of the Portfolio to purchase
or sell a portfolio security at a time when it would otherwise be favorable for
it to do so, or the possible need for the Portfolio to sell a security at a
disadvantageous time, due to the need for the Portfolio to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.

                                   MANAGEMENT
    
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the investment objective and policies of the Fund
and the Portfolio and to the general supervision of the Boards. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers and the administrators to the Fund and
the Portfolio include, but are not limited to, determining the composition of
the investment holdings of the Portfolio and placing orders to buy, sell or hold
particular securities. In addition, AIM and the Sub-adviser provide the
following administration services to the Portfolio and the Fund: furnishing
corporate officers and clerical staff; providing office space, services and
equipment; and supervising all matters relating to the Portfolio's and the
Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by the Portfolio to AIM and
the Sub-adviser. The Portfolio pays AIM a fee, based on the Portfolio's average
daily net assets at the annualized rate of .725% on the first $500 million, .70%
on the next $500 million, .675% on the next $500 million and .65% on all amounts
thereafter. Out of its aggregate fees payable by the Fund and the Portfolio, AIM
pays the Sub-adviser sub-advisory and sub-administration fees equal to 40% of
the aggregate fees AIM receives from the Fund and the Portfolio. The investment
management and administration fees paid by the Fund and the Portfolio are higher
than those paid by most mutual funds. The Fund pays all expenses not assumed by
AIM, the Sub-adviser, AIM Distributors or other agents. AIM has undertaken to
limit the Fund's expenses (exclusive of brokerage commissions,

net assets of the Fund's Class A and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
   
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B
    
 
                               Prospectus Page 15

shares of the Fund. Certain Trustees and officers of the Trust are affiliated
with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute

                       AIM GLOBAL FINANCIAL SERVICES FUND
   
an asset-based sales charge. Amounts paid in accordance with the Class B Plan
with respect to the Fund may be used to finance any activity primarily intended
to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which
    
 
                               Prospectus Page 17
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
means that the holders of a majority of the shares voting for the election of
Trustees can elect all the Trustees. A Trustee may be removed at any meeting of
the shareholders of the Trust by a vote of the shareholders owning at least
two-thirds of the outstanding shares. Any Trustee may call a special meeting of
shareholders for any purpose. Furthermore, Trustees shall promptly call a
meeting of shareholders solely for the purpose of removing one or more Trustees
when requested in writing to do so by shareholders holding 10% of the Company's
outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund when issued are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
   
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without
a sales charge and Class B shares (the "Class B shares") and Class C shares (the
"Class C shares") of the Multiple Class Funds which offer such classes are sold
at net asset value subject to a contingent deferred sales charge payable upon
certain redemptions. Class B shares of AIM DOLLAR FUND, however, may be acquired
only by an exchange of shares of another AIM Fund. These contingent deferred
sales charges are described under the caption "How to Redeem Shares -- Multiple
Distribution System." Securities dealers and other persons entitled to receive
compensation for selling or servicing shares of a Multiple Class Fund may
receive different compensation for selling or servicing one particular class of
shares over another class in the same Multiple Class Fund. Factors an investor
should consider prior to purchasing Class A, Class B or Class C shares (or, if
applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For
information on purchasing any of the AIM Funds and to receive a prospectus,
please call (800) 347-4246. As described below, the sales charge otherwise
applicable to a purchase of shares of a fund may be reduced if certain
conditions are met. In order to take advantage of a reduced sales charge, the
prospective investor or his dealer must advise AIM Distributors that the
conditions for obtaining a reduced sales charge have been met. Net asset value
is determined in the manner described under the caption "Determination of Net
Asset Value."

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:

  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;

  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9

                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

                              AIM INVESTOR'S GUIDE
or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19

                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24

                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25

taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

The Fund:                      The Fund is a non-diversified series of the Trust.

                               protection of principal.

  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The dis-
                               tributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"), Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."
                               Class B shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such shares were purchased. Class B shares redeemed after six years from the date such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."

Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a monthly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
Risk Factors:                  There is no assurance that the Fund will achieve its investment objectives. The Fund's net asset
                               value will fluctuate, reflecting fluctuations in the market value of its portfolio holdings. The
                               value of debt securities held by the Fund generally fluctuates inversely with interest rate
                               movements.
                               The Fund will invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
                               See "Investment Objectives and Policies" and "Risk Factors."

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agency, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
    The table and the assumption in the Hypothetical Example of a 5% annual
    return are required by regulation of the SEC applicable to all mutual funds;
    the 5% annual return is not a prediction of and does not represent the
    Fund's projected or actual performance.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.
    
 
   
                       AIM GLOBAL GOVERNMENT INCOME FUND

                                 [TO BE ADDED]
    
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of the maximum offering price per share
for Class A shares and net asset value per share for Class B shares.

Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of any Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
   
The Fund seeks a high level of current income by investing primarily in high
quality debt securities of the U.S. and foreign governments, their agencies and
instrumentalities. Its secondary objectives are capital appreciation and
protection of principal through active management of its maturity structure and
currency exposure. There can be no assurance that the Fund will achieve its
investment objective.
    
 
At least 65% of the Fund's total assets normally are invested in debt
obligations issued or guaranteed by the U.S. or foreign governments (including
foreign states, provinces or municipalities) or their agencies, authorities or
instrumentalities including mortgage-backed securities issued by agencies or
instrumentalities of the U.S. Government or by foreign governments. For purposes
of this policy, the Fund considers debt obligations of supranational entities
organized or supported by several national governments, such as the World Bank
and the Asian Development Bank, to be "government securities."
 
The Fund invests primarily in high quality government debt securities. "High
quality" debt securities are those rated in the top two ratings categories of
Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's, a division of
The McGraw-Hill Companies, Inc. ("S&P"), or, if not rated, determined to be of
comparable quality by the Sub-adviser. A description of Moody's and S&P ratings
is included in the Appendix to this Prospectus.
 
The Fund currently contemplates that it will invest principally in obligations
of the United States, Canada, Japan, the Western European nations, New Zealand
and Australia, as well as in multinational currency units. Under normal market
conditions, the Fund invests in issues of not less than three different
countries; investments in the securities of any one country, other than the
United States, normally represent no more than 40% of the Fund's total assets.
The Fund will not invest in a foreign currency or in securities denominated in a
foreign currency if such currency is not at the time of investment considered by
the Sub-adviser to be fully exchangeable into U.S. dollars (or a multinational
currency unit) without legal restriction.
 
   
The Fund may also invest up to 35% of its total assets in: (1) foreign
government securities that are not high quality but are rated at least
"investment grade," i.e., rated within the four highest ratings categories of
Moody's or S&P or, if not rated, determined by the Sub-adviser to be of
comparable quality; (2) corporate debt obligations of U.S. or foreign issuers
rated at least investment grade by Moody's or S&P, including debt obligations
convertible into equity securities or having attached warrants or rights to
purchase equity securities; (3) privately issued mortgage-backed and asset-
backed securities that are rated at least investment grade by Moody's or S&P, or
if unrated, determined by the Sub-adviser to be of comparable quality; and (4)
common stocks, preferred stocks and warrants to acquire such securities,
provided that the Fund will not invest more than 20% of its total assets in such
securities.

                                GENERAL POLICIES
 
   
ASSET ALLOCATION. The Fund invests in debt obligations allocated among diverse
markets and denominated in various currencies, including U.S. dollars, or in
multinational currency units such as Euros. The Fund is designed for investors
who wish to accept the risks entailed in such investments, which are different
from those associated with a portfolio consisting entirely of securities of U.S.
issuers denominated in U.S. dollars. The Fund may purchase securities that are
issued by the government or a company or financial institution of one country
but denominated in the currency of another country (or a multinational currency
unit).
    
 
   
The Sub-adviser allocates the assets of the Fund in securities of issuers in
countries and in currency denominations where the combination of fixed income
market returns, the price appreciation potential of fixed income securities and
currency exchange rate movements will present opportunities primarily for high
current income and secondarily for capital appreciation (and in the case of the
Fund, secondarily for capital appreciation and protection of principal). In so
doing, the Sub-adviser intends to take full advantage of the different yield,
risk and return characteristics that investment in the fixed income markets of
different countries can provide for U.S. investors. Fundamental economic
strength, credit quality and currency and interest rate trends are the principal
determinants of the emphasis given to various country, geographic and industry
sectors within the Fund. Securities held by the Fund may be invested without
limitation as to maturity.
    
 
The Sub-adviser selects securities of particular issuers on the basis of its
views as to the best values then currently available in the marketplace. Such
values are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political developments and variations in the supply of funds available
for investment in the world bond market relative to the demands placed upon it.
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation, interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Sub-adviser may seek to protect the Fund
against such negative currency movements through the use of sophisticated
investment techniques. See "Options, Futures and Forward Currency Transactions."
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the value of all outstanding government debt obligations throughout the world
is represented by obligations denominated in currencies other than the U.S.
dollar. Moreover, from time to time, the debt securities of issuers located
outside the United States have substantially outperformed the debt obligations
of U.S. issuers. Accordingly, the Sub-adviser believes that the Fund's policy of
investing in debt securities throughout the world may enable the achievement of
results superior to those produced by mutual funds with similar objectives to
those of the Fund that invest solely in debt securities of U.S. issuers.
    
 
   
The Fund is designed for investors who wish to accept the risks entailed in such
investments, which are different from those associated with a portfolio
consisting entirely of securities of U.S. issuers denominated in U.S. dollars.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Sub-adviser may employ a temporary defensive
investment strategy if it determines such a strategy to be warranted due to
market, economic or political conditions. Pursuant to such a defensive strategy,
the Fund temporarily may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and/or invest up to 100% of its assets in high
quality debt securities or money market instruments of U.S. or foreign issuers.
In addition, for temporary defensive purposes, most or all of the Fund's
investments may be made in the United States and denominated in U.S. dollars. To
the extent the Fund employ a temporary defensive strategy, it will not be
invested so as to achieve directly its investment objectives. In addition,
pending investment of proceeds from new sales of Fund shares or to meet ordinary
daily cash needs, the Fund may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and may invest in high quality foreign or domestic
money market instruments. For a full description of money market instruments,
see "Selection of Debt Investments" in the "Investment Objectives and Policies"
section of the Statement of Additional Information.
    
 
   
BRADY BONDS. The Fund may invest in "Brady Bonds," which are debt restructurings
that provide for the exchange of cash and loans for newly issued bonds. Brady
Bonds have been issued by the countries of Albania, Argentina, Brazil, Bulgaria,
    
 
                               Prospectus Page 8
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
Costa Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria,
Panama, Peru, Philippines, Poland, Uruguay, Venezuela and Vietnam and are
expected to be issued by other emerging market countries. As of the date of this
Prospectus, the Fund is not aware of the occurrence of any payment defaults on
Brady Bonds. Investors should recognize, however, that Brady Bonds do not have a
long payment history. In addition, Brady Bonds are often rated below investment
grade.
    
 
   
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The Fund may invest in
mortgage-backed and asset-backed securities of U.S. and foreign issuers,
including privately issued mortgage-backed and asset-backed securities.
Mortgage-backed securities represent direct or indirect interests in pools of
underlying mortgage loans that are secured by real property. Investors typically
receive payments out of the interest on and principal of the underlying
mortgages. Asset-backed securities are similar to mortgage-backed securities,
except that the underlying assets are other financial assets or financial
receivables, such as motor vehicle installment sales contracts, home equity
loans, leases of various types of real and personal property, and receivables
from credit cards. Any mortgage-backed and asset-backed securities purchased by
the Fund will be subject to the same rating requirements that apply to its other
investments. In addition, privately issued mortgage-backed and asset-backed
securities purchased by the Fund will be subject to the limitation of the Fund
which allows no more than 35% of its total assets to be invested in securities
of non-governmental issuers.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery of the securities. If the
Fund disposes of the right to acquire a when-issued security prior to its
acquisition or disposes of its right to deliver or receive against a forward
commitment, it may incur a gain or loss. At the time the Fund enters into a
transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss. The Fund may invest up to 5% of its total assets in a
combination of securities purchased on a when-issued basis or with respect to
which it has entered into forward commitment agreements.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemption of Fund
shares. The Fund also may borrow up to 5% of its total assets for temporary or
emergency purposes other than to meet redemptions. However, the Fund will not
borrow for investment purposes, nor will the Fund purchase securities while
borrowings are outstanding.
    
 
   
The Fund may also enter into reverse repurchase agreements with a bank or
recognized securities dealer. Under a reverse repurchase agreement, the Fund
would sell securities and agree to repurchase them at a particular price at a
future date. At the time the Fund enters into a reverse repurchase agreement, it
will establish and maintain a segregated account with an approved custodian
containing cash or liquid securities having a value not less than the repurchase
price, including accrued interest. Reverse repurchase agreements involve the
risk that the market value of the securities retained in lieu of sale by the
Fund may decline below the price of the securities the Fund has sold but is
obligated to repurchase. In the event the

                       AIM GLOBAL GOVERNMENT INCOME FUND
   
buyer of securities under a reverse repurchase agreement files for bankruptcy or
becomes insolvent, such buyer or its trustee or receiver may receive an
extension of time to determine whether to enforce the Fund's obligation to
repurchase the securities, and the Fund's use of the proceeds of the reverse
repurchase agreement may effectively be restricted pending such decision.
    
 
   
The Fund also may enter into "dollar rolls," in which the Fund sells fixed
income securities for delivery in the current month and simultaneously contracts
to repurchase substantially similar (same type, coupon and maturity) securities
on a specified future date. During the roll period, the Fund would forego
principal and interest paid on such securities. The Fund would be compensated by
the difference between the current sales price and the forward price for the
future purchase, as well as by the interest earned on the cash proceeds of the
initial sale. See "Investment Objectives and Policies" in the Statement of
Additional Information.
    
 
   
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Fund's assets for purposes of calculating compliance
with the Fund's borrowing limitation. See "Investment Limitations" in the
Statement of Additional Information.
    
 
   
SECURITIES LENDING. The Fund may lend its respective portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Fund to retain ownership of the securities loaned and, at the same time,
enhances the Fund's total return. At all times a loan is outstanding, the Fund
requires the borrower to maintain with the Fund's custodian, collateral
consisting of cash, U.S. government securities, or certain irrevocable letters
of credit equal to at least the value of the borrowed securities, plus any
accrued interest or such other collateral as permitted by the Fund's investment
program and regulatory agencies, and as approved by the Board. The Fund limits
its loans of portfolio securities to an aggregate of 30% of the value of its
total assets, measured at the time any such loan is made. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the loaned
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. It may also invest in zero
coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
interest in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the "interest" on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
must be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
SYNTHETIC SECURITY POSITIONS. The Fund may utilize combinations of futures on
bonds and forward currency contracts to create investment positions that have
substantially the same characteristics as bonds of the same type as those on
which the futures contracts are written. Investment positions of this type are
generally referred to as "synthetic securities."
    
 
   
For example, in order to establish a synthetic security position for the Fund
that is comparable to owning a Japanese government bond, the Sub-adviser might
purchase futures contracts on Japanese government bonds in the desired principal
amount and purchase forward currency contracts for Japanese Yen in an amount
equal to the then current purchase price for such bonds in the Japanese cash
market, with each contract having approximately the same delivery date.
    
 
   
The Sub-adviser might roll over the futures and forward currency contract
positions before taking delivery in order to continue the Fund's investment
position, or the Sub-adviser might close out those positions, thus effectively
selling the synthetic security. Further, the amount of each contract might be
adjusted in response to market conditions and the forward currency contract
might be changed
    
 
                               Prospectus Page 10
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
in amount or eliminated in order to hedge against currency fluctuations.
 
   
The Sub-adviser would create synthetic security positions for the Fund when it
believes that it can obtain a better yield or achieve cost savings in comparison
to purchasing actual bonds or when comparable bonds are not readily available in
the market. Synthetic security positions are subject to the risk that changes in
the value of purchased futures contracts may differ from changes in the value of
the bonds that might otherwise have been purchased in the cash market. Also,
while the Sub-adviser believes that the cost of creating synthetic security
positions generally will be materially lower than the cost of acquiring
comparable bonds in the cash market, the Fund will incur transaction costs in
connection with each purchase of a futures or forward currency contract. The use
of futures contracts and forward currency contracts to create synthetic security
positions also is subject to substantially the same risks as those that exist
when these instruments are used in connection with hedging strategies. See
"Options, Futures and Forward Currency Transactions" below and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies, and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the Fund's investment. The Fund may enter into such instruments
up to the full value of its portfolio assets. See "Risk Factors -- Options,
Futures and Currency Transactions" herein and "Options, Futures and Currency
Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund may also purchase and sell put and call
options on currencies, futures contracts on currencies and options on such
futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on securities
to hedge against the risk of fluctuations in the prices of securities held by
the Fund or that the Sub-adviser intends to include in the Fund's portfolio. The
Fund also may purchase and sell put and call options on indices to hedge against
overall fluctuations in the securities markets generally or in a specific market
sector.
    
 
   
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or market sector decline that could adversely affect the Fund's
portfolio. The Fund also may purchase index futures contracts and purchase call
options or write put options on such contracts to hedge against a general market
or market sector advance and thereby attempt to lessen the cost of future
securities acquisitions. The Fund may use interest rate futures contracts and
options thereon to hedge its portfolio against changes in the general level of
interest rates.
    
 
   
OTHER INDEXED SECURITIES. The Fund may invest in certain indexed securities,
which are securities whose prices are indexed to the prices of other securities,
securities indices, currencies, precious metals or other commodities, or other
financial indicators. Indexed securities typically, but not always, are debt
securities or deposits whose value at maturity or coupon rate is determined by
reference to a specific instrument or statistic. The performance of indexed
securities depends to a great extent on the performance of the security,
currency, or other instrument to which they are indexed, and may also be
influenced by interest rate changes in the United States and abroad. At the same
time, indexed securities are subject to the credit risks associated with the
issuer of the security, and their values may decline substantially if the
issuer's creditworthiness deteriorates. Indexed securities may be more volatile
than the underlying instruments. New forms of indexed securities continue to be
developed. The Fund may invest in such securities to the extent consistent with
its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed
    
 
                               Prospectus Page 11

without shareholder approval. A complete description of these limitations is
included in the Statement of Additional Information. The Fund's other investment
policies described herein and in the Statement of Additional Information may be
changed by the Trust's Board of Trustees without shareholder approval.
    
 
   
The Fund is authorized to make short sales of securities, although it has no
current intention of doing so. See "Investment Objectives and Policies -- Short
Sales" in the Statement of Additional Information.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objectives. The Fund's net asset value will fluctuate, reflecting fluctuations
in the market value of its portfolio positions and its net currency exposure.
The value of fixed income securities held by the Fund generally fluctuates
inversely with interest rate movements. Longer term bonds held by the Fund are
subject to greater interest rate risk.
    
 
   
NON-DIVERSIFIED CLASSIFICATION. The Fund is classified under the Investment
Company Act of 1940 (the "1940 Act") as a "non-diversified" fund. As a result,
the Fund will be able to invest in a fewer number of issuers than if it were
classified under the 1940 Act as a "diversified" fund. To the extent that the
Fund invests in a smaller number of issuers, the value of the Fund's shares may
fluctuate more widely and the Fund may be subject to greater investment and
credit risk with respect to its portfolio.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies. In addition, certain costs
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Fund's interest and dividends from foreign
issuers may be subject to non-U.S. withholding taxes, thereby reducing its net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the investments of the Fund in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
CURRENCY RISK. Since the Fund normally invests substantially in securities
denominated in currencies other than the U.S. dollar, and because it may hold
foreign currencies, it will be affected favorably or unfavorably by exchange
control regulations or changes in the exchange rates between such currencies and
the U.S. dollar. Changes in currency exchange rates will influence the value of
the Fund's shares, and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by the Fund. Currencies
generally are evaluated on the basis of fundamental economic criteria (e.g.,
relative inflation and interest rate levels and trends, growth rate forecasts,
balance of payments status and economic policies) as well as technical and
political data. The exchange rates between the U.S. dollar and other currencies
are determined by supply and demand in the currency exchange markets, the
international
    
 
                               Prospectus Page 12
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
balance of payments, governmental intervention, speculation and other economic
and political conditions. If the currency in which a security is denominated
appreciates against the U.S. dollar, the dollar value of the security will
increase. Conversely, a decline in the exchange rate of the currency would
adversely affect the value of the security expressed in U.S. dollars.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The yield characteristics of
mortgage-backed and asset-backed securities differ from those of traditional
bonds. Among the major differences are that interest and principal payments are
made more frequently (usually monthly) and that principal may be prepaid at any
time because the underlying mortgage loans or other assets generally may be
prepaid at any time. Generally, prepayments on fixed-rate mortgage loans will
increase during a period of falling interest rates and decrease during a period
of rising interest rates. Mortgage-backed and asset-backed securities may also
decrease in value as a result of increasing market interest rates and, because
of prepayments, may benefit less than other bonds from declining interest rates.
Reinvestments of prepayments may occur at lower interest rates than the original
investment, thus adversely affecting the yield of the Fund. Actual prepayment
experience may cause the yield of a mortgage-backed security to differ from what
was assumed when the Fund purchased the security. The market for privately
issued mortgage-backed and asset-backed securities is smaller and less liquid
than the market for U.S. government mortgage-backed securities.
    
 
Foreign mortgage-backed securities markets are substantially smaller than U.S.
markets, but have been established in several countries, including Germany,
Denmark, Sweden, Canada and Australia, and may be developed elsewhere. Foreign
mortgage-backed securities generally are structured similar to domestic
mortgage-backed securities, and they normally present substantially similar
investment risks as well as the other risks normally associated with foreign
securities.
 
   
SOVEREIGN DEBT. The Fund may invest in sovereign debt securities of emerging
market governments, including Brady Bonds. Investments in such securities
involve special risks. The issuer of the debt or the governmental authorities
that control the repayment of the debt may be unable or unwilling to repay
principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn the Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
   
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
    
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's investments.
Emerging markets are faced with social and political issues and some of them
have experienced high rates of inflation in recent years and have extensive
internal debt. Among other effects, high inflation and internal debt service
requirements may adversely affect the cost and availability of future domestic
sovereign borrowing to finance governmental programs, and may have other adverse
social, political and economic consequences. Political changes or a
deterioration of a country's domestic economy or balance of trade may affect the
willingness of countries to service their sovereign debt. Although the
Sub-adviser intends to manage the Fund in a manner that will minimize the
exposure to such risks, there can be no assurance that adverse political changes
will not cause the Fund to suffer a loss of interest or principal on any of its
holdings.
    
 
   
In recent years, some of the emerging market countries in which the Fund expects
to invest have
    
 
                               Prospectus Page 13
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
encountered difficulties in servicing their sovereign debt obligations. Some of
these countries have withheld payments of interest and/or principal of sovereign
debt. These difficulties have also led to agreements to restructure external
debt obligations -- in particular, commercial bank loans, typically by
rescheduling principal payments, reducing interest rates and extending new
credits to finance interest payments on existing debt. In the future, holders of
emerging market sovereign debt securities may be requested to participate in
similar rescheduling of such debt. Certain emerging market countries are among
the largest debtors to commercial banks and foreign governments. Currently,
Brazil, Mexico and Argentina are the largest debtors among developing countries.
At times certain emerging market countries have declared moratoria on the
payment of principal and interest on external debt; such a moratorium is
currently in effect in certain emerging market countries. There is no bankruptcy
proceeding by which a creditor may collect in whole or in part sovereign debt on
which an emerging market government has defaulted.
    
 
   
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
    
 
   
Investors should also be aware that certain sovereign debt instruments in which
the Fund may invest involve great risk. As noted above, sovereign debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to securities rated below investment grade by
Moody's and S&P. Such securities are regarded as predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligations and involve major risk exposure to
adverse conditions. Some of such securities, with respect to which the issuer
currently may not be paying interest or may be in payment default, may be
comparable to securities rated D by S&P or C by Moody's. The Fund may have
difficulty disposing of and valuing certain sovereign debt obligations because
there may be a limited trading market for such securities. Because there is no
liquid secondary market for many of these securities, the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets or in the appropriate
market sector and movements in interest rates and currency markets; (2)
imperfect correlation, or even no correlation, between movements in the price of
options, forward contracts, futures contracts or options thereon and movements
in the price of the currency or security hedged or used for cover; (3) the fact
that skills and techniques needed to trade options, futures contracts and
options thereon or to use forward currency contracts are different from those
needed to select the securities in which the Fund invests; (4) lack of assurance
that a liquid secondary market will exist for any particular option, futures
contract or option thereon at any particular time; (5) the possible loss of
principal under certain conditions; and (6) the possible inability of the Fund
to purchase or sell a portfolio security at a time when it would otherwise be
favorable for it to do so, or the possible need for the Fund to sell a security
at a disadvantageous time, due to the need for the Fund to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets, in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.

- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust and persons or companies furnishing services to the Fund,
including the investment management and administrative services agreement with
AIM, the investment sub-advisory and sub-administration agreement between AIM
and the Sub-adviser, the agreements with AIM Distributors regarding distribution
of the Fund's shares, the custody agreement and the transfer agency agreement.
The day-to-day operations of the Fund are delegated to the officers of the
Trust, subject always to the investment objectives and policies of the Fund and
to the general supervision of the Trust's Board. See "Trustees and Executive
Officers" in the Statement of Additional Information for information on the
Trustees of the Trust.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the investment portfolio of
the Fund and placing orders to buy, sell or hold particular securities. In
addition, AIM and the Sub-adviser provide the following administration services
to the Fund: furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Fund's operation.
    
 
   
The Fund pays AIM investment management and administration fees computed daily
and payable monthly, based on the average daily net assets, for such services at
the annualized rate of .725% on the first $500 million, .70% on the next $1
billion, .675% on the next $1 billion, and .65% on amounts thereafter. Out of
the aggregate fees payable by the Fund, AIM pays the Sub-adviser sub-advisory
and sub-administration fees equal to 40% of the aggregate fees AIM receives from
the Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. The Fund pays
all expenses not assumed by AIM, the Sub-adviser, AIM Distributors or any other
agents. AIM has undertaken to limit the expenses of the Class A and Class B
shares of the Fund (exclusive of brokerage commissions, taxes, interest and
extraordinary expenses) to the maximum annual rate of 1.85% and 2.50% of the
average daily net assets of the Fund's Class A and Class B shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets. The Sub-adviser also serves as the Fund's pricing and
accounting agent. For these services the Sub-adviser receives a fee at an annual
rate derived by applying 0.03% to the first $5 billion of assets of the AIM
Funds that are sub-advised by the Sub-adviser and 0.02% to the assets in excess
of $5 billion and applying that rate on the Fund's average daily net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the

                            ------------------------
 
   
In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions for the Fund may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with

<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
whom AIM Distributors has entered into selected dealer agreements. Under the
Distribution Agreement for the Class B shares, AIM Distributors sells Class B
shares of the Fund at net asset value subject to a contingent deferred sales
charge established by AIM Distributors. AIM Distributors is authorized to
advance to institutions through whom Class B shares are sold a sales commission
under schedules established by AIM Distributors. The Distribution Agreement for
the Class B shares provides that AIM Distributors (or its assignee or
transferee) will receive 0.75% (of the total 1.00% payable under the
distribution plan applicable to Class B shares) of the Fund's average daily net
assets attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.35% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.

<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Company acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares. Shares of each fund are entitled to one vote per share (with
proportional voting for fractional shares) and are freely transferable.
Shareholders have no preemptive rights. Other than the automatic conversion of
Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of

the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

                                   APPENDIX A
                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
   
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from "Aaa" to "C." Investment grade ratings are the four
categories shown:
    
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
   
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
    
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
   
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various entities in categories ranging from "AAA"
to "D" according to quality. Investment grade ratings are the four categories
shown:
    
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
                               Prospectus Page 20
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
   
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
    
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally will be evidenced by many of
the characteristics cited above but to a lesser degree. Earnings trends and
coverage ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

HOW TO PURCHASE SHARES
 
    HOW TO OPEN AN ACCOUNT.  In order to purchase shares of any of The AIM
Family of Funds ("AIM Funds"), an investor must submit a fully completed new
Account Application form directly to A I M Fund Services, Inc. ("AFS" or the
"Transfer Agent") or through any dealer authorized by A I M Distributors, Inc.
("AIM Distributors") to sell shares of the AIM Funds.
 
   
    Accounts submitted without a correct, certified taxpayer identification
number or, alternatively, a completed Internal Revenue Service ("IRS") Form W-8
(for non-resident aliens) or Form W-9 (certifying exempt status) accompanying
the registration information will be subject to backup withholding. See the
Account Application for applicable IRS penalties. The minimum initial investment
is $500, except for accounts initially established through an Automatic
Investment Plan, which requires a special authorization form (see "Special
Plans") and for certain retirement accounts. The minimum initial investment for
accounts established with an Automatic Investment Plan is $50. The minimum

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY

of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed

                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6

                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9
<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10

                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."

SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales

charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but
 
                                      A-21

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25
<PAGE>
                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.
 
   
    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MID CAP GROWTH FUND,
AIM SMALL CAP EQUITY FUND, AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION.  Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

The Fund:                      The Fund is a non-diversified series of the Trust.
 
Investment Objective:          The Fund seeks long-term capital appreciation together with current income.

                                  (Continued)
- --------------------------------------------------------------------------------
   
<TABLE>
<S>                            <C>                                               <C>
  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The dis-
                               tributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"), Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

                               Class B shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such shares were purchased. Class B shares redeemed after six years from the date such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a quarterly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset value
                               will fluctuate, reflecting fluctuations in the market value of its portfolio holdings. The value of
                               debt securities held by the Fund generally fluctuates inversely with interest rate movements. Cer-
                               tain investment grade debt securities may possess speculative qualities.
 
                               The Fund may invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.

</TABLE>
    
 
- ------------------
 
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charges permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase; the charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agent, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the example of a 5% annual return are required by regulation of the SEC
    applicable to all mutual funds. The 5% annual return is not a prediction of
    and does not represent the Fund's projected or actual performance.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of the maximum offering price per share
for Class A shares and net asset value per share for Class B shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                        AIM GLOBAL GROWTH & INCOME FUND
 
                              INVESTMENT OBJECTIVE
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital appreciation together with
current income. The Fund seeks its objective by investing in a global portfolio
of both equity and debt securities, allocated among diverse international
markets. There is no assurance that the Fund will achieve its investment
objective.
    
 
At least 65% of the Fund's total assets normally will be invested in a
combination of blue-chip equity securities and high quality government bonds.
The Fund considers an equity security to be "blue chip" if: (i) during the
issuer's most recent fiscal year the security offered an above average dividend
yield relative to the latest reported dividend yield on the Morgan Stanley
Capital International World Index; AND (ii) the total equity market
capitalization of the issuer is at least $1 billion. Government bonds are deemed
to be high quality if at the time of the Fund's investment they are rated within
one of the two highest ratings categories of Moody's Investors Service, Inc.
("Moody's") or by Standard & Poor's, a division of The McGraw-Hill Companies,
Inc. ("S&P"), or, if not rated, are deemed to be of equivalent quality in the
judgment of the Sub-adviser.
 
Up to 35% of the Fund's total assets may be invested in other equity securities
and investment grade government and corporate debt obligations which the
Sub-adviser believes will assist the Fund in achieving its objective.
"Investment grade" debt securities are those rated within one of the four
highest ratings categories of Moody's or S&P, or, if not rated, deemed to be of
equivalent quality in the judgment of the Sub-adviser.
 
Equity securities that the Fund may purchase include common stocks, preferred
stocks and warrants to acquire such stocks and other equity securities.
Government bonds that the Fund may purchase include debt obligations issued or
guaranteed by the United States or foreign governments (including foreign
states, provinces or municipalities) or their agencies, authorities or
instrumentalities and debt obligations of supranational entities organized or
supported by several national governments, such as the World Bank and the Asian
Development Bank. The debt obligations held by the Fund may include debt
obligations convertible into equity securities or having attached warrants or
rights to purchase equity securities. The Fund may purchase securities that are
issued by the government or a corporation or financial institution of one nation
but denominated in the currency of another nation (or a multinational currency
unit).
 
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the total equity market capitalization worldwide is represented by non-U.S.
equity securities, and more than 50% of the value of all outstanding government
debt obligations throughout the world is represented by obligations denominated
in currencies other than the U.S. dollar. Moreover, from time to time the equity
and debt securities of issuers located outside the United States have
substantially outperformed the equity and debt securities of U.S. issuers.
Accordingly, the Sub-adviser believes that the Fund's policy of investing in a
global portfolio of equity and debt securities may enable the achievement of
long-term results superior to those produced by mutual funds with similar
objectives to that of the Fund that invest solely in U.S. equity and debt
securities.
 
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. Consistent with the Fund's
investment objective, the Sub-adviser employs a conservative investment style in
managing the Fund's assets. In so doing the Sub-adviser attempts to limit
volatility and risk to capital. The Sub-adviser allocates the Fund's assets
among securities of countries and in currency denominations where opportunities
for meeting the Fund's investment objective are expected to be the most
attractive. The Sub-adviser attempts to identify those countries and industries
where economic and political factors are likely to produce above-average growth
rates and to further identify companies in such countries and industries that
are best positioned and managed to benefit from these factors.
 
The Fund currently contemplates that it will invest principally in securities of
issuers in the United States, Canada, Japan, Western Europe, New Zealand and
Australia. The Fund may invest substantially in securities denominated in one or
more currencies. Under normal conditions, the
 
                               Prospectus Page 7
<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
Fund invests in issuers of not less than three different countries and issuers
of any one country, other than the United States, will represent no more than
40% of the Fund's total assets.
 
The relative proportions of equity and debt securities held by the Fund at any
one time will vary, depending upon the Sub-adviser's assessment of global
political and economic conditions and the relative strengths and weaknesses of
the world equity and debt markets. To enable the Fund to respond to general
economic changes and market conditions around the world, the Fund is authorized
to invest up to 100% of its total assets in either equity securities or debt
securities.
 
In selecting equity securities for investment, the Sub-adviser attempts to
identify and acquire only securities it deems to represent high or improving
investment quality. Securities representing high investment quality generally
will include those of well-known, established and successful issuers that the
Sub-adviser believes will continue to be successful in the future. Securities
representing improving investment quality may include those of an issuer that
has improved its sales or earnings or of an issuer the balance sheet and
financial condition of which is improving. The Sub-adviser seeks to avoid
investing in equity securities that appear overly speculative or risky, even if
they have attractive features or investment potential.
 
In evaluating debt securities considered for the Fund, the Sub-adviser analyzes
their yield, maturity, issue classification and quality characteristics, coupled
with expectations regarding local and world economies, movements in the general
level and term of interest rates, currency values, political developments, and
variations in the supply of funds available for investment in the world bond
market relative to the demands placed upon it. There are no limitations on the
maximum or minimum maturities of the debt securities considered by the Fund or
on the average weighted maturity of the debt portion of the Fund's portfolio.
Should the rating of a debt security be revised while such security is owned by
the Fund, the Sub-adviser will evaluate what action, if any, is appropriate with
respect to such security.
 
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation and interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Fund may seek to protect itself against
negative currency movements by engaging in hedging techniques through the use of
options, futures and forward currency contracts.
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Fund may hold cash (U.S.
dollars, foreign currencies or multinational currency units such as Euros) and/
or invest any portion or all of its assets in high quality money market
instruments of U.S. or foreign issuers. In addition, for temporary defensive
purposes, most or all of the Fund's investments may be made in the United States
and denominated in U.S. dollars. To the extent the Fund adopts a temporary
defensive posture, it will not be invested so as to directly achieve its
investment objective. In addition, pending investment of proceeds from new sales
of Fund shares or in order to meet ordinary daily cash needs, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units) and may
invest in foreign or domestic high quality money market instruments. For a full
description of money market instruments, see "Money Market Instruments" in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemption of Fund
shares. The Fund also may borrow up to 5% of its total assets for temporary or
emergency purposes other than to meet redemptions. The Fund may borrow up to
33 1/3% of its total assets. However, the Fund will not purchase securities
while borrowings in excess of 5% of the Fund's total assets are outstanding. Any
borrowing by the Fund may cause greater fluctuation in the value of its shares
than would be the case if the Fund did not borrow.
 
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Fund's sale of securities together with its
commitment (for which the Fund may receive a fee) to purchase similar, but not
identical, securities at a future date.

<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
 
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least 100% of the value of the
borrowed securities, plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral should the borrower fail financially.
 
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's net investment income from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing the Fund's net investment
income.
 
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic or
economic developments which could affect the Fund's investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, rate of savings and capital reinvestment, resource
self-sufficiency and balance of payments positions. Investments in foreign
government securities involve special risks, including the risk that the
government issuers may be unable or unwilling to repay principal and interest
when due.
 
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between such currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. To attempt to increase
return, the Fund may write call options on securities. This strategy will be
employed only when, in the opinion of the Sub-adviser, the size of the premium
the Fund receives for writing the option is adequate to compensate the Fund
against the risk that appreciation in the underlying security may not be fully
realized if the option is exercised. The Fund also is authorized to write put
options to attempt to enhance return, although it does not have the current
intention of so doing.
 
The Fund may also use forward currency contracts, futures contracts, options on
securities, options on currencies, options on indices and options on futures
contracts to attempt to hedge against the overall level of investment and
currency risk normally associated with the Fund's investments. These instruments
are often referred to as "derivatives," which may be defined as financial
instruments whose performance is derived, at least in part, from the performance
of another asset (such as a security, currency, or an index of securities). The
Fund may enter into such instruments up to the full value of its portfolio
assets. See "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
 
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar, or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund also may purchase and sell put and call
options on currencies, futures contracts on
 
                               Prospectus Page 9
<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
currencies and options on such futures contracts to hedge the Fund's portfolio
against movements in exchange rates.
 
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
stock indices to hedge against overall fluctuations in the securities markets or
in a specific market sector.
 
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or a specific market sector decline that could adversely affect the
Fund's portfolio. The Fund also may purchase index futures contracts and
purchase call options or write put options on such contracts to hedge against a
general market or market sector advance and thereby attempt to lessen the cost
of future securities acquisitions. Similarly, the Fund may use interest rate
futures contracts and options thereon to hedge the debt portion of its portfolio
against changes in the general level of interest rates.
 
Although the Fund is authorized to enter into options, futures and forward
currency transactions, the Fund might not enter into any such transactions.
Options, futures and foreign currency transactions involve certain risks, which
include: (1) dependence on the Sub-adviser's ability to predict movements in the
prices of individual securities, fluctuations in the general securities markets
and movements in interest rates and currency markets; (2) imperfect correlation,
or even no correlation, between movements in the price of forward contracts,
options, futures contracts or options thereon and movements in the price of the
currency or security hedged or used for cover; (3) the fact that the skills and
techniques needed to trade options, futures contracts and options thereon or to
use forward currency contracts are different from those needed to select the
securities in which the Fund invests; (4) the lack of assurance that a liquid
secondary market will exist for any particular option, futures contract or
option thereon at any particular time; (5) the possible loss of principal under
certain conditions; and (6) the possible inability of the Fund to purchase or
sell a portfolio security at a time when it would otherwise be favorable for it
to do so, or the possible need for the Fund to sell a security at a
disadvantageous time, due to the need for the Fund to maintain "cover" or to set
aside securities in connection with hedging transactions.
 
OTHER POLICIES AND RISKS. The Fund's net asset value will fluctuate, reflecting
fluctuations in the market value of its portfolio positions. Equity securities,
particularly common stocks, generally represent the most junior position in an
issuer's capital structure, and entitle holders to an interest in the assets of
an issuer, if any, remaining after all more senior claims have been satisfied.
The value of equity securities held by the Fund will fluctuate in response to
general market and economic developments, as well as developments affecting the
particular issuers of such securities. In addition, the value of debt securities
held by the Fund generally will fluctuate with changes in the perceived
creditworthiness of the issuers of such securities and movements in interest
rates. Investment grade debt securities rated Baa by Moody's are described by
Moody's as having speculative characteristics, and therefore may be affected by
economic conditions and changes in the circumstances of their issuers to a
greater extent than higher rated bonds.
 
The Fund may invest up to 15% of its net assets in illiquid securities and other
securities for which no readily available market exists. The Fund may also
invest up to 5% of its total assets in a combination of securities purchased on
a when-issued basis or with respect to which it has entered into forward
commitment agreements.
 
The Fund is classified under the Investment Company Act of 1940, as amended
("1940 Act") as a "non-diversified" fund. As a result, the Fund will be able to
invest in a fewer number of issuers than if it were classified under the 1940
Act as a "diversified" fund. To the extent that the Fund invests in a smaller
number of issuers, the value of the Fund's shares may fluctuate more widely and
the Fund may be subject to greater investment and credit risk with respect to
its portfolio.
 
OTHER INFORMATION. The Fund's investment objective may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the

Statement of Additional Information. Unless specifically noted, the Fund's
investment policies described in this Prospectus and in the Statement of
Additional Information may be changed by the Trust's Board of Trustees without
shareholder approval. The Fund's policies regarding lending, and the percentage
of Fund assets that may be committed to borrowing, are fundamental policies and
may not be changed without shareholder approval. If a percentage restriction on
investment or utilization of assets in an investment policy or restriction is
adhered to at the time an investment is made, a later change in percentage
ownership of a security or kind of securities resulting from changing market
values or a similar type of event will not be considered a violation of the
Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day-to-day operations of the Fund are delegated to the officers
of the Trust, subject always to the objective and policies of the Fund and to
the general supervision of the Trust's Board of Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the Fund's portfolio and
placing orders to buy, sell or hold particular securities; furnishing corporate
officers and clerical staff; providing office space, services and equipment; and
supervising all matters relating to the Fund's operation. For these services,
the Fund pays AIM investment management and administration fees, computed daily
and paid monthly, based on the average daily net assets, at the annualized rate
of .975% on the first $500 million, .95% on the next $500 million, .925% on the
next $500 million and .90% on amounts thereafter. Out of the aggregate fees
payable by the Fund, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit the Fund's expenses (exclusive of brokerage commissions,
taxes, interest and extraordinary expenses) to the annual rate of 1.75% and
2.40% of the average daily net assets of the Fund's Class A and Class B shares,
respectively.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th

Francisco, California 94111, and 1166 Avenue of the Americas, New York, New York
10036, serves as the sub-adviser to the Fund pursuant to an investment
sub-advisory and sub-administration agreement dated as of May 29, 1998. Prior to
May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset Management, Inc.
On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the former indirect
parent organization of the Sub-adviser, consummated a purchase agreement with
AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset Management
Division, which included the Sub-adviser and certain other affiliates. As a
result of this transaction, the Sub-adviser is now an indirect wholly owned
subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and its worldwide
asset management affiliates provided investment management and/or administrative
services to institutional, corporate and individual clients around the world
since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser.
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of

                        AIM GLOBAL GROWTH & INCOME FUND
   
the Fund (individually referred to as a "Distribution Agreement" or collectively
as the "Distribution Agreements.") with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
Class A and Class B shares of the Fund. Certain Trustees and officers of the
Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.35% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of
    
 
                               Prospectus Page 13
<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
   
the average daily net assets attributable to the Fund's Class B shares to
selected dealers and financial institutions who furnish continuing personal
shareholder services to their customers who purchase and own Class B shares of
the Fund. Any amounts not paid as a service fee would constitute an asset-based
sales charge. Amounts paid in accordance with the Class B Plan with respect to
the Fund may be used to finance any activity primarily intended to result in the
sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998 the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and the
Trust's other funds will be voted in the aggregate on other

<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
   
matters, such as the election of Trustees and ratification of the selection of
the Trust's independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without
a sales charge and Class B shares (the "Class B shares") and Class C shares (the
"Class C shares") of the Multiple Class Funds which offer such classes are sold
at net asset value subject to a contingent deferred sales charge payable upon
certain redemptions. Class B shares of AIM DOLLAR FUND, however, may be acquired
only by an exchange of shares of another AIM Fund. These contingent deferred
sales charges are described under the caption "How to Redeem Shares -- Multiple
Distribution System." Securities dealers and other persons entitled to receive
compensation for selling or servicing shares of a Multiple Class Fund may
receive different compensation for selling or servicing one particular class of
shares over another class in the same Multiple Class Fund. Factors an investor
should consider prior to purchasing Class A, Class B or Class C shares (or, if
applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For
information on purchasing any of the AIM Funds and to receive a prospectus,
please call (800) 347-4246. As described below, the sales charge otherwise
applicable to a purchase of shares of a fund may be reduced if certain
conditions are met. In order to take advantage of a reduced sales charge, the
prospective investor or his dealer must advise AIM Distributors that the
conditions for obtaining a reduced sales charge have been met. Net asset value
is determined in the manner described under the caption "Determination of Net
Asset Value."

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9
<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

                              AIM INVESTOR'S GUIDE
or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an

<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24

                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25

taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

                               to  be held, and other circumstances. Investors  should consider whether, during the anticipated life
                               of their investment  in the Fund,  the accumulated  distribution fees and  any applicable  contingent
                               deferred  sales charges on Class  B shares prior to  conversion would be less  than the initial sales
                               charge and accumulated distribution fees on  Class A shares purchased at  the same time, and to  what
                               extent  such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the  table under the caption "'Table  of Fees and Expenses" sets  forth
                               examples  of the charges  applicable to each  class of shares.  Class A shares  will normally be more
                               beneficial than Class B shares  to the investor who qualifies  for reduced initial sales charges,  as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The  Fund is among those mutual funds distributed  by AIM Distributors (collectively, "The AIM Family
                               of Funds") Class A and Class B shares of the  Fund may be exchanged for shares of other funds in  The
                               AIM  Family of  Funds in the  manner and subject  to the policies  and charges set  forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may  redeem all or a portion of  their shares at net asset value  on
                               any  business day, generally  without charge. A contingent  deferred sales charge of  1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How  to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."
 
                               Class  B shareholders of the Fund may  redeem all or a portion of  their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years  from
                               the  date such  shares were purchased.  Class B shares  redeemed after  six years from  the date such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."

                                  (Continued)
- --------------------------------------------------------------------------------
   
<TABLE>
<S>                            <C>                                               <C>
Distributions:                 The Fund currently  declares and  pays dividends from  net investment  income, if any,  on an  annual
                               basis.  The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales  charge
                               in  the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset value
                               will fluctuate, reflecting fluctuations  in the market  value of its  portfolio holdings. The  Fund's
                               policy  of concentrating  its investments  in companies  in its  particular industries  may cause the
                               Fund's net asset value to fluctuate more than if it invested in a greater number of industries.
 
                               The Fund may invest in foreign securities.  Investments in foreign securities involve risks  relating
                               to  political and economic developments  abroad and the differences  between the regulations to which
                               U.S. and foreign  issuers are  subject. Individual  foreign economies  also may  differ favorably  or
                               unfavorably  from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid  and their prices more volatile  than those of securities of  comparable
                               U.S. companies.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against  the overall  level of investment  and currency risk  associated with its  present or planned
                               investments. Such transactions involve certain risks and transaction costs.
 
                               The Fund  may invest  up  to 5%  of  its total  assets in  below  investment grade  debt  securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

- ------------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agency, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the Hypothetical Example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital appreciation. It seeks its
objective by investing primarily in equity securities of health care companies
throughout the world. There can be no assurance that the Fund will achieve its
investment objective.
    
 
   
At least 65% of the Fund's total assets normally will be invested in common and
preferred stocks, and warrants to acquire such securities, issued by health care
companies. A "health care" company is an entity in which (i) at least 50% of
either the revenues or earnings was derived from health care activities, or (ii)
at least 50% of the assets was devoted to such activities, based on the
company's most recent fiscal year. The remainder of the Fund's assets may be
invested in debt securities issued by health care companies and/or equity and
debt securities of companies outside of the health care industry, which, in the
opinion of the Sub-adviser, stand to benefit from developments in the health
care industries.
    
 
GLOBAL HEALTH CARE INDUSTRIES INVESTMENT. Examples of health care companies
include those that are substantially engaged in the design, manufacture or sale
of products or services used for or in connection with health care or medicine.
Such firms may include pharmaceutical companies; firms that design, manufacture,
sell or supply medical, dental and optical products, hardware or services;
companies involved in biotechnology, medical diagnostic, and biochemical
research and development; and companies involved in the ownership and/or
operation of health care facilities.
 
   
The Fund expects that, from time to time, a significant portion of its assets
may be invested in the securities of U.S. issuers. Health care industries,
however, are global industries with significant, growing markets outside of the
United States. A sizeable portion of the companies which comprise the health
care industries are headquartered outside of the United States, and many
important pharmaceutical and biotechnology discoveries and technological
breakthroughs have occurred outside of the United States, primarily in Japan,
the United Kingdom and Western Europe.
    
 
The Sub-adviser believes that the global health care industries offer attractive
long-term supply/ demand dynamics. While the United States, Western Europe, and
Japan presently account for a substantial portion of health care expenditures,
this should change dramatically in the coming decade if the populations of
developing countries devote an increasing percentage of income to health care.
Additionally, the Sub-adviser believes demographics on aging point to a
significant increase in demand from the industrialized nations, as the elderly
account for a growing proportion of worldwide health care spending. Finally, in
the Sub-adviser's view, technology will continue to expand the range of products
and services offered, with new drugs, medical devices and surgical procedures
addressing medical conditions previously considered untreatable.
 
In addition to these underlying trends, the United States is presently
experiencing a period of rapid and profound change in its own health care
system, marked by the rise of managed care, the formation of health care
delivery networks, and widespread consolidation across all segments of the
industry. The Sub-adviser believes that this transition offers investment
opportunities in those companies acting as consolidators or otherwise gaining
market share at the expense of less efficient competitors.
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION.
    
   
The Fund expects that, from time to time, a significant portion of its assets
may be invested in the securities of domestic issuers. The industry represented
in the Fund, however, is a global industry with significant, growing markets
outside of the United States. A sizeable proportion of the companies which
comprise the health care industries are headquartered outside of the United
States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Fund. The Sub-adviser uses its financial expertise in
markets located throughout the world and the substantial global resources of
AMVESCAP PLC in attempting to identify those countries and companies then
providing the greatest potential for long-term capital appreciation. In this
fashion, the Sub-adviser seeks to
    
 
                               Prospectus Page 7
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
   
enable shareholders to capitalize on the substantial investment opportunities
and the potential for long-term growth of capital presented by the global
industries represented in the Fund.
    
 
   
The Sub-adviser allocates the Fund's assets among securities of countries and in
currency denominations where opportunities for meeting the Fund's investment
objective are expected to be the most attractive. The Fund may invest
substantially in securities denominated in one or more currencies. Under normal
conditions, the Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 50% of the Fund's total assets.
    
 
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Fund may invest up to 100%
of its total assets in cash (U.S. dollars, foreign currencies or multinational
currency units such as Euros) and/or high quality debt securities or money
market instruments of U.S. or foreign issuers. In addition, for temporary
defensive purposes, most or all of the Fund's investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund adopts a
temporary defensive posture, it will not be invested so as to achieve directly
its investment objective. In addition, pending investment of proceeds from new
sales of Fund shares or to meet its ordinary daily cash needs, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units) and may
invest in foreign or domestic high quality money market instruments. For a full
description of money market instruments, see "Money Market Instruments" in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Fund to participate in privatizations may be limited by local law,
or the terms on which the Fund may be permitted to participate may be less
advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Fund may invest up to 10% of its
total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Fund would
bear its ratable share of that investment company's expenses, including its
advisory and administration fees. At the same time, the Fund would continue to
pay its own management fees and other expenses. AIM and the Sub-adviser will
waive their advisory fees to the extent that the Fund invests in an Affiliated
Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemptions of the
Fund's shares. The Fund also may borrow up to 5% of its total assets for
temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Fund may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Fund's borrowings exceed 5% of its
total assets. Any borrowing by the Fund may cause greater fluctuation in the
value of its shares than would be the case if the Fund did not borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Fund's sale of securities together with its
commitment (for which the Fund may receive a fee) to purchase similar, but not
identical, securities at a future date.

SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least the value of the
borrowed securities, plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral should the borrower fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities or enter into forward commitments only with the
intention of actually receiving or delivering the securities, as the case may
be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery to the Fund. If
the Fund disposes of the right to acquire a when-issued security prior to its
acquisition or disposes of its right to deliver or receive against a forward
commitment, it may incur a gain or loss. At the time the Fund enters into a
transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Fund may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
stock indexes to hedge against overall fluctuations in the securities markets
generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Fund's holdings. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.

OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the Investment
Objectives and Policies section of the Statement of Additional Information.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. The Fund's net asset values will fluctuate reflecting fluctuations in
the market value of the Fund's portfolio positions. Equity securities,
particularly common stocks, generally represent the most junior position in an
issuer's capital structure, and entitle holders to an interest in the assets of
an issuer, if any, remaining after all more senior claims have been satisfied.
The value of equity securities held by the Fund will fluctuate in response to
general market and economic developments, as well as developments affecting the
particular issuers of such securities. In addition, the value of debt securities
held by the Fund generally will fluctuate with changes in the perceived
creditworthiness of the issuers of such securities and interest rates.
    
 
   
Because the Fund focuses its investments on particular industries, an investment
in each may be more volatile than that of other investment companies that do not
concentrate their investments in such a manner. Moreover, the value of the
shares of the Fund will be especially susceptible to factors affecting the
industries in which it focuses. Accordingly, the Fund should not be considered a
complete investment program.
    
 
   
HEALTH CARE INDUSTRIES. Health care industries generally are subject to
substantial governmental regulation. Changes in governmental policy or
regulation could have a material effect on the demand for products and services
offered by companies in the health care industries and therefore could affect
the performance of the Fund. Regulatory approvals are generally required before
new drugs and medical devices or procedures may be introduced and before the
acquisition of additional facilities by health care providers. In addition, the
products and services offered by such companies may be subject to rapid
obsolescence caused by technological and scientific advances.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs
    
 
                               Prospectus Page 10
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
   
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Fund's interest and dividends from foreign
issuers may be subject to non-U.S. withholding taxes, thereby reducing the
Fund's net investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the Fund's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Fund may invest in issuers domiciled in "emerging markets." Investing in
emerging market countries involves risks in addition to those risks involved in
foreign investing. Many emerging market countries have experienced high rates of
inflation for many years. In addition, emerging markets generally are dependent
heavily upon international trade and, accordingly, have been and continue to be
affected adversely by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. The securities markets of emerging
market countries are substantially smaller, less developed, less liquid and more
volatile than the securities markets of the developed countries. In addition,
issuers in emerging markets typically are subject to a greater degree of change
in earnings and business prospects than issuers in developed countries.
    
 
   
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Funds' shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Fund may invest up to 5% of its total assets
in below investment grade debt securities, that is, rated below BBB by Standard
& Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa by
Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Fund will not invest in debt securities that
are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience
 
                               Prospectus Page 11
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
financial stress. During such periods, such issuers may not have sufficient
revenues to meet their interest payment obligations. The issuer's ability to
service its debt obligations may also be adversely affected by specific
developments affecting the issuer, such as the issuer's inability to meet
specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Fund. If an issuer exercises these provisions in a declining
interest rate market, the Fund may have to replace the security with a lower
yielding security, resulting in a decreased return for investors. In addition,
the Fund may have difficulty disposing of lower quality securities because they
may have a thin trading market. There may be no established retail secondary
market for many of these securities, and the Fund anticipates that such
securities could be sold only to a limited number of dealers or institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on market prices of such instruments and may make it more difficult for the Fund
to obtain accurate market quotations for purposes of valuing the Fund's
portfolio investments. The Fund may also acquire lower quality debt securities
during an initial underwriting or which are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Fund may also incur additional expenses to the extent it
is required to seek recovery upon a default in the payment of principal or
interest on portfolio holdings, and the Fund may have limited legal recourse in
the event of a default.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Fund to achieve
capital appreciation substantially exceeding the appreciation the Fund would
realize if it did not make such investments. However, in order to attempt to
limit investment risk, the Fund will invest no more than 5% of its total assets
in Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets or in the appropriate
market sector and movements in interest rates and currency markets; (2)
imperfect correlation, or even no correlation, between movements in the price of
options, forward contracts, futures contracts or options thereon and movements
in the price of the currency or security hedged or used for cover; (3) the fact
that skills and techniques needed to trade options, futures contracts and
options thereon or to use forward currency contracts are different from those
needed to select the securities in which the Fund invests; (4) lack of assurance
that a liquid secondary market will exist for any particular option, futures
contract or option thereon at any particular time; (5) the possible loss of
principal under certain conditions; and (6) the possible inability of the Fund
to purchase or sell a portfolio security at a time when it would otherwise be
favorable for it to do so, or the possible need for the Fund to sell a security
at a disadvantageous time, due to the need for the Fund to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Fund's portfolio normally will include
securities of established suppliers of traditional products and services, the
Fund may invest in smaller companies which can benefit from the development of
new products and services. These smaller companies may present greater
opportunities for capital appreciation, but may also involve greater risks than
large, established issuers. Such smaller companies
    
 
                               Prospectus Page 12
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
may have limited product lines, markets or financial resources, and their
securities may trade less frequently and in more limited volume than the
securities of larger, more established companies. As a result, the prices of the
securities of such smaller companies may fluctuate to a greater degree than the
prices of the securities of other issuers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day-to-day operations of the Fund is delegated to the officers of
the Trust, subject always to the investment objective and policies of the Fund
and to the general supervision of the Trust's Board of Trustees. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the investment portfolio of
the Fund and placing orders to buy, sell or hold particular securities. In
addition, AIM and the Sub-adviser provide the following administration services
to the Fund: furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Funds' operation.
    
 
   
For investment management and administration services provided to the Fund, the
Fund pays AIM a fee computed daily and paid monthly based on the Fund's average
daily net assets at the annualized rate of .975% on the first $500 million, .95%
on the next $500 million, .925% on the next $500 million and .90% on amounts
thereafter. Out of the aggregate fees payable by the Fund, AIM pays the
Sub-adviser sub-advisory and sub-administration fees equal to 40% of the
aggregate fees AIM receives from the Fund. The investment management and
administration fees paid by the Fund are higher than those paid by most mutual
funds.
    
 
   
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 2.00% and 2.50% of the average daily net assets of the Fund's Class A
and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain

other affiliates. As a result of this transaction, the Sub-adviser is now an
indirect wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the
Sub-adviser and its worldwide asset management affiliates provided investment
management and/or administrative services to institutional, corporate and
individual clients around the world since 1969.
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions may be executed through affiliates of
AIM or the Sub-adviser. High portfolio turnover (over 100%) involves
correspondingly greater brokerage commissions and other transaction costs that
the Funds will bear directly and could result in the realization of net capital
gains which would be taxable when distributed to shareholders. See "Dividends,
Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into Master Distribution Agreement, dated May
29, 1998 on behalf of Class A shares of the Fund, and has entered into a Master
Distribution Agreement, dated May 29, 1998, on behalf of Class B shares of the
Fund (individually referred to as a "Distribution Agreement" or collectively as
the "Distribution Agreements") with AIM Distributors, a registered broker-dealer
and a wholly owned subsidiary of AIM, to act as the distributor of Class A and
Class B shares of the Fund. Certain Trustees and officers of the Trust are
affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.

DISTRIBUTION PLANS. CLASS A PLAN.  The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.

                          AIM GLOBAL HEALTH CARE FUND
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealer as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of any class over another.

Statement of Additional Information.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may continue to establish other
funds, each corresponding to a distinct investment portfolio and a distinct
series of the Trust's shares at beneficial interest. Shares of each fund are
entitled to one vote per share (with proportional voting for fractional shares)
and are freely transferable. Shareholders have no preemptive rights. Other than
the automatic conversion of Class B shares to Class A shares, there are no
conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges, except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

below under "Special Information Relating to Multiple Class Funds." For

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of

the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10

                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,
established for tax-qualified group annuities, for contracts purchased on or
before June 30, 1992. AIM Distributors acts as distributor for the AIM Funds
which represent a range of different investment objectives and policies. As set
forth under the caption "Terms and Conditions of Purchase of the AIM Funds --
Sales Charges and Dealer Concessions," shares of certain of the AIM Funds,
including the Class A shares of the Multiple Class Funds, listed below and
referred to herein as the "Load Funds," are sold at a public offering price that
includes a maximum sales charge of 5.50% or 4.75% of the public offering price
of such shares; Class A shares (or shares which normally involve the payment of
initial sales charges) of certain of the AIM Funds, listed below and referred to
herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain

                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD

EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other

taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

The Fund and the Portfolio:    The Fund is a non-diversified series of the Trust. The Portfolio is a non- diversified, open-end
                               management investment company.
 
Investment Objectives:         The Fund primarily seeks high current income and secondarily seeks capital appreciation.
 
Principal Investments:         The Fund invests all of its investable assets in the Portfolio, which, in turn, invests primarily in
                               debt securities of issuers located in emerging markets.
 
Investment Managers:           The Portfolio is managed by A I M Advisors, Inc. ("AIM") and is sub-advised and sub-administered by
                               INVESCO (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or administrative services to institutional, corporate
                               and individual clients around the world. AIM and the Sub-adviser are both indirect wholly owned
                               subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its subsidiaries are an independent investment

                               company portfolios.

                               prospectus, the Fund also offers Advisor Class shares, which represent interests in the Fund. The
                               Advisor Class has different distribution arrangements.

  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The dis-
                               tributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, " The AIM Family
                               of Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a monthly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve its investment objectives. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of its or its
                               corresponding Portfolio's portfolio holdings. The value of debt securities held by the Portfolio
                               generally fluctuates inversely with interest rate movements.
 
                               The Portfolio will invest in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               or the Portfolio's net asset value, earnings and gains and losses realized on sales of securities.
                               Securities of foreign companies may be less liquid and their prices more volatile than those of
                               securities of comparable U.S. companies. The Portfolio will normally invest at least 65% of its total
                               assets in debt securities of issuers in emerging markets. Such investments entail greater risks than
                               investing in securities of issuers in developed markets.
 
                               The Portfolio may engage in certain foreign currency, options and futures transactions to attempt to
                               hedge against the overall level of investment and currency risk associated with its present or
                               planned investments. Such transactions involve certain risks and transaction costs.
 
                               The Portfolio may invest up to 100% of its total assets in debt securities rated below investment
                               grade or, if not rated, determined by the Sub-adviser to be of comparable quality. Investments of
                               this type are subject to greater risk of loss of principal and interest.

- --------------
 
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agency, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information. The Board of Trustees of the Trust
    believes that the aggregate per share expenses of the Fund and the Portfolio
    will be less than or approximately equal to the expenses which the Fund
    would incur if the assets of the Fund were invested directly in the type of
    securities being held by the Portfolio.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES MAY BE MORE OR LESS
    THAN THOSE SHOWN. The table and the assumption in the Hypothetical Example
    of a 5% annual return are required by regulation of the SEC applicable to
    all mutual funds; the 5% annual return is not a prediction of and does not
    represent the Fund's or the Portfolio's projected or actual performance.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.
    
 
   
                          AIM GLOBAL HIGH INCOME FUND

                                 [TO BE ADDED]
    
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of the maximum offering price per share
for Class A shares and net asset value per share for Class B shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.

From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.
    
 
- --------------------------------------------------------------------------------
 
   
                             INVESTMENT OBJECTIVES
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund primarily seeks high current income, and secondarily seeks capital
appreciation. It seeks its objectives by investing all of its investable assets
in the Portfolio, which in turn seeks the same objectives as the Fund by
normally investing at least 65% of its total assets in debt securities of
issuers in emerging markets. There can be no assurance that the Fund or the
Portfolio will achieve its investment objectives.
    
 
The Portfolio intends to invest in the following types of debt securities:
bonds, notes and debentures of emerging market governments; securities issued or
guaranteed by such governments' agencies or instrumentalities; securities issued
or guaranteed by the central banks of emerging market countries; and securities
issued by other banks and companies in such countries and securities denominated
in or indexed to the currencies of emerging markets. Under current market
conditions, the Portfolio expects its investments in emerging market securities
to consist substantially of Brady Bonds (see "General Policies -- Brady Bonds,"
below) and other sovereign debt securities.
 
The Portfolio may also invest up to 35% of its total assets in (1) equity
securities of issuers in emerging markets included in the list below under the
caption "Emerging Markets"; (2) equity and debt securities of issuers in
developed countries, including the United States; (3) securities of issuers in
emerging markets not included in the emerging markets list, if investing therein
becomes feasible and desirable subsequent to the date of this Prospectus; and
(4) cash and money market instruments. In evaluating investments in securities
of issuers in developed markets, the Sub-adviser will consider, among other
things, the business activities of the issuer in emerging markets and the impact
that developments in emerging markets are likely to have on the issuer's
financial condition.
 
Under normal circumstances, substantially all of the Portfolio's assets will be
invested in debt securities of both governmental and corporate issuers in
emerging markets. Emerging markets debt securities generally are considered to
have a credit quality below investment grade, as defined above. Lower quality
securities involve a high degree of risk and are predominantly speculative.
These debt securities are the equivalent of high yield, high risk bonds,
commonly known as "junk bonds." See "Risk Factors." Many emerging market debt
securities are not rated by U.S. ratings agencies such as Moody's and S&P. The
Portfolio's ability to achieve its investment objectives is thus more dependent
on the Sub-adviser's credit analysis. The Portfolio may invest in securities
that are in default as to payment of principal and/or interest.
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, investors
should be aware that the Fund, unlike mutual funds that directly acquire and
manage their own portfolios of securities, seeks to achieve its investment
objectives by investing all of its investable assets in the Portfolio, which is
a separate investment company. Because the Fund will invest only in the
Portfolio, the Fund's shareholders will acquire only an indirect interest in the
investments of the Portfolio.
    
 
   
The Fund may redeem its investment from the Portfolio at any time, if the Board
of Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment
objectives, policies or limitations that is not approved by the Board or the
shareholders of the Fund could require the Fund to redeem its interest in the
Portfolio. Any such redemption could result in a distribution in kind of
portfolio securities (as opposed to a cash distribution) by the Portfolio. In
addition, a distribution in kind could result in a less diversified portfolio of
investments for the Fund and could adversely
    
 
                               Prospectus Page 7
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
affect its liquidity. Upon redemption, the Board would consider what action
might be taken, including the investment of all the investable assets of the
Fund in another pooled investment entity having substantially the same
investment objectives as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objectives, policies and limitations discussed herein.
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may experience different
returns than investors in another investment company that invests exclusively in
the Portfolio. As of the date of this Prospectus, the Fund is the only
institutional investor in the Portfolio.
    
 
   
Investors in the Fund should be aware that the Fund's investment in the
Portfolio may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.
    
 
                                GENERAL POLICIES
 
   
ASSET ALLOCATION. The Portfolio invests in debt obligations allocated among
diverse markets and denominated in various currencies, including U.S. dollars,
or in multinational currency units such as Euros. The Fund is designed for
investors who wish to accept the risks entailed in such investments, which are
different from those associated with a portfolio consisting entirely of
securities of U.S. issuers denominated in U.S. dollars. The Portfolio may
purchase securities that are issued by the government or a company or financial
institution of one country but denominated in the currency of another country
(or a multinational currency unit).
    
 
   
The Sub-adviser allocates the assets of the Portfolio in securities of issuers
in countries and in currency denominations where the combination of fixed income
market returns, the price appreciation potential of fixed income securities and
currency exchange rate movements will present opportunities primarily for high
current income and secondarily for capital appreciation. In so doing, the Sub-
adviser intends to take full advantage of the different yield, risk and return
characteristics that investment in the fixed income markets of different
countries can provide for U.S. investors. Fundamental economic strength, credit
quality and currency and interest rate trends are the principal determinants of
the emphasis given to various country, geographic and industry sectors within
the Portfolio. Securities held by the Portfolio may be invested in without
limitation as to maturity.
    
 
The Sub-adviser selects securities of particular issuers on the basis of its
views as to the best values then currently available in the marketplace. Such
values are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political developments and variations in the supply of funds available
for investment in the world bond market relative to the demands placed upon it.
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation, interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Sub-adviser may seek to protect the
Portfolio against such negative currency movements through the use of
sophisticated investment techniques. See "Options, Futures and Forward Currency
Transactions" and "Swaps, Caps, Floors and Collars."
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the value of all outstanding government debt obligations throughout the world
is represented by obligations denominated in currencies other than the U.S.
dollar. Moreover, from time to time, the debt securities of issuers located
outside the United States have substantially outperformed the debt obligations
of U.S. issuers. Accordingly, the Sub-adviser believes that the Portfolio's
policy of
    
 
                               Prospectus Page 8
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
investing in debt securities of issuers in emerging markets may enable the
achievement of results superior to those produced by mutual funds with similar
objectives to those of the Fund and the Portfolio that invest solely in debt
securities of U.S. issuers.
    
 
   
The Fund is designed for investors who wish to accept the risks entailed in such
investments, which are different from those associated with a portfolio
consisting entirely of securities of U.S. issuers denominated in U.S. dollars.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Sub-adviser may employ a temporary defensive
investment strategy if it determines such a strategy to be warranted due to
market, economic or political conditions. Pursuant to such a defensive strategy,
the Portfolio temporarily may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and/or invest up to 100% of its respective assets
in high quality debt securities or money market instruments of U.S. or foreign
issuers. In addition, for temporary defensive purposes, most or all of the
Portfolio's investments may be made in the United States and denominated in U.S.
dollars. To the extent the Portfolio employs a temporary defensive strategy, it
will not invest so as to achieve directly its investment objectives. In
addition, pending investment of proceeds from new sales of Fund shares or to
meet ordinary daily cash needs, the Portfolio may hold cash (U.S. dollars,
foreign currencies or multinational currency units) and may invest in high
quality foreign or domestic money market instruments. For a full description of
money market instruments, see "Selection of Debt Investments" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
   
EMERGING MARKET SECURITIES. The Portfolio considers "emerging markets" to
consist of all countries determined by the Sub-adviser to have developing or
emerging economies and markets. These countries generally include every country
in the world except the United States, Canada, Japan, Australia, New Zealand and
most countries located in Western Europe. The Portfolio will consider investment
in the following emerging markets:

The Portfolio will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements, overly burdensome repatriation
requirements and similar restrictions, the lack of organized and liquid
securities markets, unacceptable political risks or for other reasons.
    
 
As used in this Prospectus and the Statement of Additional Information, an
issuer in an emerging market is an entity: (i) for which the principal
securities trading market is an emerging market, as defined above; (ii) that
(alone or on a consolidated basis) derives 50% or more of its total revenue from
either goods produced, sales made or services performed in emerging markets; or
(iii) organized under the laws of, or with a principal office in, an emerging
market.
 
   
BRADY BONDS. The Portfolio may invest in "Brady Bonds," which are debt
restructurings that provide for the exchange of cash and loans for newly issued
bonds. Brady Bonds have been issued by the countries of Albania, Argentina,
Brazil, Bulgaria, Costa Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan,
Mexico, Nigeria, Panama, Peru, Philippines, Poland, Uruguay, Venezuela and
Vietnam and are expected to be issued by other emerging market countries. As of
the date of this Prospectus, the Portfolio is not aware of the occurrence of any
payment defaults on Brady Bonds. Investors should recognize, however, that Brady
Bonds do not have a long payment history. In addition, Brady Bonds are often
rated below investment grade.

<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
 
   
The Portfolio may invest in either collateralized or uncollateralized Brady
Bonds. U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed
rate par bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Portfolio may invest in fixed and
floating rate loans ("Loans") arranged through private negotiations between a
foreign entity and one or more financial institutions ("Lenders"). The majority
of the Portfolio's investments in Loans in emerging markets is expected to be in
the form of participations in Loans ("Participations") and assignments of
portions of Loans from third parties ("Assignments"). Participations typically
will result in the Portfolio having a contractual relationship only with the
Lender, not with the borrower government. The Portfolio will have the right to
receive payments of principal, interest and any fees to which it is entitled
only from the Lender selling the Participation and only upon receipt by the
Lender of the payments from the borrower. In connection with purchasing
Participations, the Portfolio generally will have no right to enforce compliance
by the borrower with the terms of the loan agreement relating to the loan ("Loan
Agreement"), nor any rights of set-off against the borrower, and the Portfolio
may not directly benefit from any collateral supporting the Loan in which it has
purchased the Participation. As a result, the Portfolio will assume the credit
risk of both the borrower and the Lender that is selling the Participation.
    
 
   
In the event of the insolvency of the Lender selling a Participation, the
Portfolio may be treated as a general creditor of the Lender and may not benefit
from any set-off between the Lender and the borrower. The Portfolio will acquire
Participations only if the Lender interpositioned between the Portfolio and the
borrower is determined by the Sub-adviser to be creditworthy. When the Portfolio
purchases Assignments from Lenders, the Portfolio will acquire direct rights
against the borrower on the Loan. However, since Assignments are arranged
through private negotiations between potential assignees and assignors, the
rights and obligations acquired by the Portfolio as the purchaser of an
Assignment may differ from, and be more limited than, those held by the
assigning Lender.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities and forward commitments only with the
intention of actually receiving or delivering the securities, as the case may
be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery of the
securities. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
The Portfolio may also sell securities on a "when, as and if issued" basis for
hedging purposes. Under such a transaction, the Portfolio is required to deliver
at a future date a security it does not presently hold, but which it has a right
to receive if the security is issued. Issuance of the security may not occur, in
which case the Portfolio would have no obligation to the other party, and would
not receive payment for the sale. Selling securities on a "when, as and if
issued" basis may reduce risk of loss to the extent that such a sale wholly or
partially offsets unfavorable price movements on the investments being hedged.
However, such sales also limit the amount the Portfolio can receive if the
"when, as and if issued" security is in fact issued.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio is
authorized to borrow money from banks in an amount up to 33 1/3% of its total
assets (including the amount borrowed), less all liabilities and indebtedness
other
    
 
                               Prospectus Page 10
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
than the borrowings and may use the proceeds of such borrowings for investment
purposes. The Portfolio will borrow for investment purposes only when the
Sub-adviser believes that such borrowings will benefit the Portfolio after
taking into account considerations such as the costs of the borrowing and the
likely investment returns on the securities purchased with the borrowed monies.
    
 
   
Borrowing for investment purposes is known as leveraging, which is a speculative
practice. Such borrowing by the Portfolio creates the opportunity for increased
net income and appreciation but, at the same time, involves special risk
considerations. For example, leveraging might exaggerate changes in the net
asset value of Fund shares and in the yield realized by the Portfolio. Although
the principal amount of such borrowings will be fixed, the Portfolio's assets
may change in value during the time the borrowing is outstanding. By leveraging
the Portfolio, changes in net asset values, higher or lower, may be greater in
degree than if leverage was not employed. To the extent the income derived from
the assets obtained with borrowed funds exceeds the interest and other expenses
that the Portfolio will have to pay, the Portfolio's net income will be greater
than if borrowing was not used. Conversely, if the income from the assets
obtained with borrowed funds is not sufficient to cover the cost of borrowing,
the net income of the Portfolio will be less than if borrowing were not used,
and therefore the amount available for distribution to shareholders as dividends
will be reduced. The Portfolio each expects that some of its borrowings may be
made on a secured basis.
    
 
   
In addition to the foregoing borrowings, the Portfolio may borrow money for
temporary or emergency purposes or payments in an amount not exceeding 5% of the
value of its total assets (not including the amount borrowed) provided that the
total amount borrowed by the Portfolio for any purpose does not exceed 33 1/3%
of its total assets.
    
 
   
The Portfolio may also enter into reverse repurchase agreements with a bank or
recognized securities dealer. Under a reverse repurchase agreement, the
Portfolio would sell securities and agree to repurchase them at a particular
price at a future date. At the time the Portfolio enters into a reverse
repurchase agreement, it will establish and maintain a segregated account with
an approved custodian containing cash or liquid securities having a value not
less than the repurchase price, including accrued interest. Reverse repurchase
agreements involve the risk that the market value of the securities retained in
lieu of sale by the Portfolio may decline below the price of the securities the
Portfolio has sold but is obligated to repurchase. In the event the buyer of
securities under a reverse repurchase agreement files for bankruptcy or becomes
insolvent, such buyer or its trustee or receiver may receive an extension of
time to determine whether to enforce the Portfolio's obligation to repurchase
the securities, and the Portfolio's use of the proceeds of the reverse
repurchase agreement may effectively be restricted pending such decision.
    
 
   
The Portfolio also may enter into "dollar rolls," in which the Portfolio sells
fixed income securities for delivery in the current month and simultaneously
contracts to repurchase substantially similar (same type, coupon and maturity)
securities on a specified future date. During the roll period, the Portfolio
would forego principal and interest paid on such securities. The Portfolio would
be compensated by the difference between the current sales price and the forward
price for the future purchase, as well as by the interest earned on the cash
proceeds of the initial sale. See "Investment Objectives and Policies" in the
Statement of Additional Information.
    
 
   
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Portfolio's assets for purposes of calculating
compliance with the Portfolio's borrowing limitation. See "Investment
Limitations" in the Statement of Additional Information.
    
 
   
SECURITIES LENDING. The Portfolio may lend its respective portfolio securities
to broker/dealers or to other institutional investors. Securities lending allows
a Fund to retain ownership of the securities loaned and, at the same time,
enhances a Fund's total return. At all times a loan is outstanding, the
Portfolio requires the borrower to maintain with the Portfolio's custodian,
collateral consisting of cash, U.S. government securities, or certain
irrevocable letters of credit equal to at least the value of the borrowed
securities, plus any accrued interest or such other collateral as permitted by a
Fund's investment program and regulatory agencies, and as approved by the Board.
The Portfolio limits its loans of portfolio securities to an aggregate of 30% of
the value of its total assets, measured at the time any such loan is made. The
risks in lending portfolio securities, as with other extensions of secured
credit, consist of possible delays in receiving additional collateral or in
recovery of the loaned securities and possible loss of rights in the collateral
should the borrower fail financially.
    
 
                               Prospectus Page 11
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
 
   
ZERO COUPON SECURITIES. The Portfolio may invest in certain zero coupon
securities that are "stripped" U.S. Treasury notes and bonds. They also may
invest in zero coupon and other deep discount securities issued by foreign
governments and domestic and foreign corporations, including certain Brady Bonds
and other foreign debt and in payment-in-kind securities. Zero coupon securities
pay no interest to holders prior to maturity, and payment-in-kind securities pay
interest in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the "interest" on
payment-in-kind securities will be included in the Portfolio's income.
Accordingly, for a Fund to continue to qualify for tax treatment as a regulated
investment company and to avoid a certain excise tax (see "Taxes" in the
Statement of Additional Information), it may be required to distribute an amount
that is greater than its share of the total amount of cash the Portfolio
actually receives. These distributions must be made from the Fund's, or its
share of the Portfolio's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Portfolio will not be able to purchase
additional income-producing securities with cash used to make such
distributions, and its current income ultimately may be reduced as a result.
Zero coupon and payment-in-kind securities usually trade at a deep discount from
their face or par value and will be subject to greater fluctuations of market
value in response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
SYNTHETIC SECURITY POSITIONS. The Portfolio may utilize combinations of futures
on bonds and forward currency contracts to create investment positions that have
substantially the same characteristics as bonds of the same type as those on
which the futures contracts are written. Investment positions of this type are
generally referred to as "synthetic securities."
    
 
   
For example, in order to establish a synthetic security position the Portfolio
that is comparable to owning a Japanese government bond, the Sub-adviser might
purchase futures contracts on Japanese government bonds in the desired principal
amount and purchase forward currency contracts for Japanese Yen in an amount
equal to the then current purchase price for such bonds in the Japanese cash
market, with each contract having approximately the same delivery date.
    
 
   
The Sub-adviser might roll over the futures and forward currency contract
positions before taking delivery in order to continue the Portfolio's investment
position, or the Sub-adviser might close out those positions, thus effectively
selling the synthetic security. Further, the amount of each contract might be
adjusted in response to market conditions and the forward currency contract
might be changed in amount or eliminated in order to hedge against currency
fluctuations.
    
 
   
The Sub-adviser would create synthetic security positions for the Portfolio when
it believes that it can obtain a better yield or achieve cost savings in
comparison to purchasing actual bonds or when comparable bonds are not readily
available in the market. Synthetic security positions are subject to the risk
that changes in the value of purchased futures contracts may differ from changes
in the value of the bonds that might otherwise have been purchased in the cash
market. Also, while the Sub-adviser believes that the cost of creating synthetic
security positions generally will be materially lower than the cost of acquiring
comparable bonds in the cash market, the Portfolio will incur transaction costs
in connection with each purchase of a futures or forward currency contract. The
use of futures contracts and forward currency contracts to create synthetic
security positions also is subject to substantially the same risks as those that
exist when these instruments are used in connection with hedging strategies. See
"Options, Futures and Forward Currency Transactions" below and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies, and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the Portfolio's investment. The Portfolio also may enter into
interest rate, currency and index swaps and purchase or sell related caps,
floors and collars and other similar instruments. See "Swaps, Caps, Floors and
Collars" below. These instruments are often referred to as "derivatives," which
may be defined as financial instruments whose performance is derived, at least
in part, from the performance of another asset (such as a security, currency or
an index of securities). The Portfolio may enter into such instruments up to the
full value of its portfolio assets. See "Risk Factors -- Options, Futures and
Forward Currency Transactions" herein and "Options, Futures and Currency
    
 
                               Prospectus Page 12
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
Strategies" in the Statement of Additional Information.
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to the Portfolio's portfolio positions. The Portfolio also may purchase
and sell put and call options on currencies, futures contracts on currencies and
options on such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on
securities to hedge against the risk of fluctuations in the prices of securities
held by the Portfolio or that the Sub-adviser intends to include in the
Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on indices to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general market or market sector decline that could adversely affect the
Portfolio's holdings. The Portfolio also may purchase index futures contracts
and purchase call options or write put options on such contracts to hedge
against a general market or market sector advance and thereby attempt to lessen
the cost of future securities acquisitions. The Portfolio may use interest rate
futures contracts and options thereon to hedge its portfolio against changes in
the general level of interest rates.
    
 
   
SWAPS, CAPS, FLOORS AND COLLARS. The Portfolio may enter into interest rate,
currency and index swaps, and purchase or sell related caps, floors and collars
and other derivative instruments. The Portfolio expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, to protect against currency fluctuations, as a
technique for managing the portfolio's duration (I.E., the price sensitivity to
changes in interest rates) or to protect against any increase in the price of
securities the Portfolio anticipates purchasing at a later date. The Portfolio
intends to use these transactions as hedges, and neither will sell interest rate
caps or floors if it does not own securities or other instruments providing an
income stream roughly equivalent to what the Portfolio may be obligated to pay.
    
 
   
Interest rate swaps involve the exchange by the Portfolio with another party of
their respective commitments to pay or receive interest (for example, an
exchange of floating rate payments for fixed rate payments) with respect to a
notional amount of principal. A currency swap is an agreement to exchange cash
flows on a notional amount based on changes in the values of the reference
indices.
    
 
The purchase of a cap entitles the purchaser to receive payments on a notional
principal amount from the party selling the cap to the extent that a specified
index exceeds a predetermined interest rate. The purchase of an interest rate
floor entitles the purchaser to receive payments on a notional principal amount
from the party selling the floor to the extent that a specified index falls
below a predetermined interest rate or amount. A collar is a combination of a
cap and a floor that preserves a certain return within a predetermined range of
interest rates or values.
 
   
INDEXED COMMERCIAL PAPER. The Portfolio may invest without limitation in
commercial paper which is indexed to certain specific foreign currency exchange
rates. The terms of such commercial paper provide that its principal amount is
adjusted upwards or downwards (but not below zero) at maturity to reflect
changes in the exchange rate between two currencies while the obligation is
outstanding. The Portfolio will purchase such commercial paper with the currency
in which it is denominated and, at maturity, will receive interest and principal
payments thereon in that currency, but the amount of principal payable by the
issuer at maturity will change in proportion to the change (if any) in the
exchange rate between the two specified currencies between the date the
instrument is issued and the date the instrument matures. While such commercial
paper entails the risk of loss of principal, the potential for realizing gains
as a result of changes in foreign currency exchange rates enables the Portfolio
to hedge against a decline in the U.S. dollar value of investments denominated
in foreign currencies while seeking to provide an attractive money market rate
of return. The Portfolio will not purchase such commercial paper for
speculation.
    
 
   
OTHER INDEXED SECURITIES. The Portfolio may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of
    
 
                               Prospectus Page 13
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
other securities, securities indices, currencies, precious metals or other
commodities, or other financial indicators. Indexed securities typically, but
not always, are debt securities or deposits whose value at maturity or coupon
rate is determined by reference to a specific instrument or statistic. The
performance of indexed securities depends to a great extent on the performance
of the security, currency, or other instrument to which they are indexed, and
may also be influenced by interest rate changes in the United States and abroad.
At the same time, indexed securities are subject to the credit risks associated
with the issuer of the security, and their values may decline substantially if
the issuer's creditworthiness deteriorates. Indexed securities may be more
volatile than the underlying instruments. New forms of indexed securities
continue to be developed. The Portfolio may invest in such securities to the
extent consistent with its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this prospectus
and in the Statement of Additional Information are not fundamental policies and
may be changed by the Company's Board of Trustees without shareholder approval.
The investment policies of the Fund are identical to the investment policies of
the portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objectives, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objectives.
    
 
   
The Fund is authorized to make short sales of securities, although it has no
current intention of doing so. See "Investment Objectives and Policies -- Short
Sales" in the Statement of Additional Information.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Portfolio's investment policies or restrictions.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objectives. The Portfolio's net asset value will fluctuate,
reflecting fluctuations in the market value of its portfolio positions and its
net currency exposure. The value of fixed income securities held by the
Portfolio generally fluctuates inversely with interest rate movements. Longer
term bonds held by the Portfolio are subject to greater interest rate risk.
    
 
   
NON-DIVERSIFIED CLASSIFICATION. The Fund and the Portfolio are classified under
the Investment Company Act of 1940 (the "1940 Act") as a "non-diversified" fund.
As a result, the Portfolio will be able to invest in a fewer number of issuers
than if it were classified under the 1940 Act as a "diversified" fund. To the
extent that the Portfolio invests in a smaller number of issuers, the value of
the Fund's shares may fluctuate more widely and the Portfolio may be subject to
greater investment and credit risk with respect to the portfolios.
    
 
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform
 
                               Prospectus Page 14
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
accounting, auditing and financial reporting standards, practices and
requirements comparable to those applicable to U.S. companies. In addition,
certain costs attributable to foreign investing, such as custody charges, are
higher than those attributable to domestic investing. Securities of some foreign
companies are less liquid and their prices may be more volatile than securities
of comparable domestic companies. The Portfolio's interest and dividends from
foreign issuers may be subject to non-U.S. withholding taxes, thereby reducing
their net investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the investments of the Portfolio in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, rate of savings and capital reinvestment, resource
self-sufficiency and balance of payments positions.
    
 
   
CURRENCY RISK. Since the Portfolio normally invests substantially in securities
denominated in currencies other than the U.S. dollar, and because they may hold
foreign currencies, they will be affected favorably or unfavorably by exchange
control regulations or changes in the exchange rates between such currencies and
the U.S. dollar. Changes in currency exchange rates will influence the value of
the Fund's shares, and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by the Fund. Currencies
generally are evaluated on the basis of fundamental economic criteria (e.g.,
relative inflation and interest rate levels and trends, growth rate forecasts,
balance of payments status and economic policies) as well as technical and
political data. The exchange rates between the U.S. dollar and other currencies
are determined by supply and demand in the currency exchange markets, the
international balance of payments, governmental intervention, speculation and
other economic and political conditions. If the currency in which a security is
denominated appreciates against the U.S. dollar, the dollar value of the
security will increase. Conversely, a decline in the exchange rate of the
currency would adversely affect the value of the security expressed in U.S.
dollars.
    
 
In addition, many of the currencies in emerging market countries have
experienced steady devaluations relative to the U.S. dollar and major
devaluations have historically occurred in certain countries.
 
   
INVESTING IN EMERGING MARKETS. Because of the special risks associated with
investing in emerging markets, an investment in the Portfolio should be
considered speculative. Investors are strongly advised to consider carefully the
special risks involved in emerging markets, which are in addition to the usual
risks of investing in developed foreign markets around the world.
    
 
   
Investing in emerging markets involves risks relating to potential political and
economic instability within such markets and the risks of expropriation,
nationalization, confiscation of assets and property or the imposition of
restrictions on foreign investment and on repatriation of capital invested. In
the event of such expropriation, nationalization or other confiscation in any
emerging market, the Portfolio could lose its entire investment in that market.
    
 
Many emerging market countries have experienced substantial, and in some periods
extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain emerging market
countries.
 
Economies in emerging markets generally are dependent heavily upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values and other protectionist measures imposed or negotiated by the countries
with which they trade. These economies also have been and may continue to be
affected adversely by economic conditions in the countries in which they trade.
 
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
United States and other more developed countries. Disclosure and regulatory
standards in many respects are less stringent than in the United States and
other major markets. There also may be a lower level of monitoring and
regulation of emerging securities markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
 
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to
 
                               Prospectus Page 15
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
emerging markets. Such markets have different settlement and clearance
procedures. In certain markets there have been times when settlements have been
unable to keep pace with the volume of securities transactions, making it
difficult to conduct such transactions. The inability of the Portfolio to make
intended securities purchases due to settlement problems could cause the
Portfolio to forego attractive investment opportunities. Inability to dispose of
a portfolio security caused by settlement problems could result either in losses
to the Portfolio due to subsequent declines in value of the portfolio security
or, if the Portfolio has entered into a contract to sell the security, could
result in possible liability to the purchaser.
    
 
   
The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading of securities may cease or may be
substantially curtailed and prices for the Portfolio's portfolio securities in
such markets may not be readily available. Section 22(e) of the 1940 Act permits
a registered investment company to suspend redemption of its shares for any
period during which an emergency exists, as determined by the SEC. Accordingly,
when the Portfolio believes that appropriate circumstances warrant, it will
promptly apply to the SEC for a determination that an emergency exists within
the meaning of Section 22(e) of the 1940 Act. During the period commencing from
the Portfolio's identification of such conditions until the date of SEC action,
the portfolio securities of the Portfolio in the affected markets will be valued
at fair value as determined in good faith by or under the direction of the
Trust's or the Portfolio's Boards of Trustees.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Portfolio may have difficulty disposing
of Assignments and Participations. The liquidity of such securities is limited
and the Portfolio anticipates that such securities could be sold only to a
limited number of institutional investors. The lack of a liquid secondary market
could have an adverse impact on the value of such securities and on the
Portfolio's ability to dispose of particular Assignments or Participations when
necessary to meet the Portfolio's liquidity needs or in response to a specific
economic event, such as a deterioration in the creditworthiness of the borrower.
The lack of a liquid secondary market for Assignments and Participations also
may make it more difficult for the Portfolio to assign a value to those
securities for purposes of valuing the Portfolio's portfolio and calculating its
net asset value.
    
 
   
SOVEREIGN DEBT. The Portfolio may invest in sovereign debt securities of
emerging market governments, including Brady Bonds. Investments in such
securities involve special risks. The issuer of the debt or the governmental
authorities that control the repayment of the debt may be unable or unwilling to
repay principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn a Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Portfolio's
investments. Emerging markets are faced with social and political issues and
some of them have experienced high rates of inflation in recent years and have
extensive internal debt. Among other effects, high inflation and internal debt
service requirements may adversely affect the cost and availability of future
domestic sovereign borrowing to finance governmental programs, and may have
other adverse social, political and economic consequences. Political changes or
a deterioration of a

<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
country's domestic economy or balance of trade may affect the willingness of
countries to service their sovereign debt. Although the Sub-adviser intends to
manage the Portfolio in a manner that will minimize the exposure to such risks,
there can be no assurance that adverse political changes will not cause the
Portfolio to suffer a loss of interest or principal on any of its holdings.
    
 
   
In recent years, some of the emerging market countries in which the Portfolio
expects to invest have encountered difficulties in servicing their sovereign
debt obligations. Some of these countries have withheld payments of interest
and/or principal of sovereign debt. These difficulties have also led to
agreements to restructure external debt obligations -- in particular, commercial
bank loans, typically by rescheduling principal payments, reducing interest
rates and extending new credits to finance interest payments on existing debt.
In the future, holders of emerging market sovereign debt securities may be
requested to participate in similar rescheduling of such debt. Certain emerging
market countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by which a creditor may collect in whole or in
part sovereign debt on which an emerging market government has defaulted.
    
 
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
 
   
Investors should also be aware that certain sovereign debt instruments in which
the Portfolio may invest involve great risk. As noted above, sovereign debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to securities rated below investment grade by
Moody's and S&P. Such securities are regarded as predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligations and involve major risk exposure to
adverse conditions. Some of such securities, with respect to which the issuer
currently may not be paying interest or may be in payment default, may be
comparable to securities rated D by S&P or C by Moody's. The Portfolio may have
difficulty disposing of and valuing certain sovereign debt obligations because
there may be a limited trading market for such securities. Because there is no
liquid secondary market for many of these securities, the Portfolio anticipates
that such securities could be sold only to a limited number of dealers or
institutional investors.
    
 
   
LOWER QUALITY DEBT SECURITIES. Under normal market conditions the Portfolio may
invest up to 100% of the Portfolio's total assets in debt securities rated below
investment grade. Such investments involve a high degree of risk.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest quality debt that is not in default as to
principal or interest and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than higher quality securities with regard to a deterioration of general
economic conditions. These securities are the equivalent of high yield, high
risk bonds, commonly known as "junk bonds." As noted above, the Portfolio may
invest in debt securities rated below C, which are in default as to principal
and/or interest.
    
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit quality in
 
                               Prospectus Page 17
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
response to subsequent events, so that an issuer's current financial condition
may be better or worse than a rating indicates. See "Appendix A" for a
discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because there may be a thin trading market for such securities. There
may be no established retail secondary market for many of these securities, and
the Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing the securities in the Portfolio. Adverse
publicity and investor perceptions, whether or not based on fundamental
analysis, may also decrease the values and liquidity of lower quality
securities, especially in a thinly traded market. The Portfolio also may acquire
lower quality debt securities during an initial underwriting or may acquire
lower quality debt securities which are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
Factors having an adverse effect on the market value of lower rated securities
or their equivalents purchased by the Portfolio will adversely impact net asset
value of the Fund. See "Risk Factors" in the Statement of Additional
Information. In addition to the foregoing, such factors may include: (i)
potential adverse publicity; (ii) heightened sensitivity to general economic or
political conditions; and (iii) the likely adverse impact of a major economic
recession. The Portfolio also may incur additional expenses to the extent it is
required to seek recovery upon a default in the payment of principal or interest
on its portfolio holdings, and the Portfolio may have limited legal recourse in
the event of a default. Debt securities issued by governments in emerging
markets can differ from debt obligations issued by private entities in that
remedies from defaults generally must be pursued in the courts of the defaulting
government, and legal recourse is therefore somewhat diminished. Political
conditions, in terms of a government's willingness to meet the terms of its debt
obligations, also are of considerable significance. There can be no assurance
that the holders of commercial bank debt may not contest payments to the holders
of debt securities issued by governments in emerging markets in the event of
default by the governments under commercial bank loan agreements.
    
 
   
As of October 31, 1997, the Portfolio had 86.59% of its total net assets in debt
securities that received a rating from Moody's and 10.29% of its total net
assets in debt securities that were not so rated. In addition, the Portfolio had
3.12%, of its total net assets in cash and net receivables. The Portfolio had
the following percentages of its total net assets invested in rated securities:
Aaa -- 7.99%, Aa -- 0.00%, A -- 0.00%, Baa -- 13.11%, Ba -- 48.56%, B -- 16.93%,
Caa -- 0.00%, Ca -- 0.00%, C -- 0.00%. Included under the unrated category are
securities held by the Portfolio's total net assets which have been determined
by the Sub-adviser to be of comparable quality to securities in the following
rating categories: Ba -- 3.22%; and B -- 7.07%. It should be noted that the
allocation of the investments of the Portfolio by rating on

                          AIM GLOBAL HIGH INCOME FUND
   
any given date will vary and should not be considered representative of the
future portfolio composition of the Portfolio.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. In addition, issuers in
emerging markets typically are subject to a greater degree of change in earnings
and business prospects than issuers in developed countries. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the Portfolio to sell a security at a disadvantageous time, due to the need for
the Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets, in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.

- --------------------------------------------------------------------------------
 
   
The Trust's and the Portfolio's Boards of Trustees have overall responsibility
for the operation of the Fund and the Portfolio, respectively. The Trust's and
Portfolio's Boards of Trustees have approved all significant agreements between
the Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the objective and policies of the Fund and the
Portfolio and to the general supervision of the Boards. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Portfolio's investment managers and administrators include,
but are not limited to, determining the composition of the investment holdings
of the Portfolio and placing orders to buy, sell or hold particular securities.
In addition, AIM and the Sub-adviser provide the following administration
services to the Fund and the Portfolio: furnishing corporate officers and
clerical staff; providing office space, services and equipment; and supervising
all matters relating to the Portfolio's operation.

The Fund pays AIM administration fees at the annualized rate of 0.25% of the
Fund's average daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by the Portfolio to AIM and
the Sub-adviser. The Portfolio pays AIM such fees, based on the average daily
net assets of the Portfolio at the annualized rate of .475% on the first $500
million, .45% on the next $1 billion, .425% on the next $1 billion and .40% on
amounts thereafter, plus 2% of the Portfolio's total investment income as stated
in the Portfolio's Statement of Operations, calculated in accordance with
generally accepted accounting principles, adjusted daily for currency
revaluations, on a marked to market basis, of the Portfolio's assets; provided,
however, that during any fiscal year this amount shall not exceed 2% of the
Portfolio's total investment income calculated in accordance with generally
accepted accounting principles. Out of its aggregate fees payable by the Fund
and the Portfolio, AIM pays the Sub-adviser sub-advisory and sub-administration
fees equal to 40% of the aggregate fees AIM receives from the Fund and the
Portfolio. The investment management and administration fees paid by the Fund
and the Portfolio are higher than those paid by most mutual funds. The Fund and
Portfolio pay all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the expenses of the Class A and
Class B shares of the Fund (and the Fund's pro-rata portion of the Portfolio's
expenses) to the maximum annual rate of 2.25% and 2.85% of the average daily net
assets of the Fund's Class A and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices, including investment offices in Atlanta, Boston,
Dallas, Denver, Louisville, Miami, Portland (Oregon), Frankfurt, Hong Kong,
London, Singapore, Sydney, Tokyo and Toronto. In managing the Fund and the
Portfolio, the Sub-adviser employs a team approach, taking advantage of its
investment resources around the world.

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions for the Portfolio may be
executed through affiliates of AIM or the Sub-adviser. High portfolio turnover
(over 100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund or the Portfolio will bear directly and could
result in the realization of net capital gains which would be taxable when
distributed to shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to
    
 
                               Prospectus Page 21

                          AIM GLOBAL HIGH INCOME FUND
   
compensate AIM Distributors for the purpose of financing any activity that is
intended to result in the sale of Class A shares of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.35% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its

ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust.
    
 
   
From time to time, the Trust may establish other funds, each corresponding to a
distinct investment portfolio and a distinct series of the Trust's shares of
beneficial interest. Shares of each fund are entitled to one vote per share
(with proportional voting for fractional shares) and are freely transferable.
Shareholders have no preemptive rights. Other than the automatic conversion of
Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a Delaware business
trust. Under Delaware law, the Fund and other entities that invest in the
Portfolio enjoy the same limitations of liability extended to shareholders of
private, for-profit corporations. There is a remote possibility, however, that
under certain circumstances an investor in the Portfolio may be held liable for
the Portfolio's
    
 
                               Prospectus Page 23
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
obligations. However, the Agreement and Declaration of Trust of the Portfolio
disclaims shareholder liability for acts or obligations of the Portfolio and
requires that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by the Portfolio or a trustee. The
Agreement and Declaration of Trust also provides for indemnification from the
Portfolio property for all losses and expenses of any shareholder held
personally liable for the Portfolio's obligations. Thus the risk of an investor
incurring financial loss on account of such liability is limited to
circumstances in which the Portfolio itself would be unable to meet its
obligations and where the other party was held not to be bound by the
disclaimer.
    
 
   
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of Fund shareholders and will cast its vote as
instructed by Fund shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
    
 
   
COUNSEL The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

                                   APPENDIX A
                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from "Aaa" to "C." Investment grade ratings are the first
four categories:
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered as well-assured. Often the protection of
    interest and principal payments may be very moderate, and thereby not well
    safeguarded during both good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B -- Bonds which are rated B generally lack characteristics of the
    desirable investment. Assurance of interest and principal payments or of
    maintenance of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa are of poor standing. Such issues may
    be in default or there may be present elements of danger with respect to
    principal or interest.
 
        Ca -- Bonds which are rated Ca represent obligations which are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are rated C are the lowest rated class of bonds, and
    issues so rated can be regarded as having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.
 
                               Prospectus Page 25
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various entities in categories ranging from "AAA"
to "D" according to quality. Investment grade ratings are the first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations rated "BB," "B," "CCC," "CC," and "C"
    are regarded as having significant speculative characteristics. "BB"
    indicates the least degree of speculation and "C" the highest. While such
    obligations will likely have some quality and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An obligation rated "BB" is less vulnerable to nonpayment than
    other speculative issues. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate capacity to meet its financial commitment
    on the obligation.
 
        B -- An obligation rated "B" is more vulnerable to nonpayment than
    obligations rated "BB," but the obligor currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its financial commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to have the capacity to meet its financial commitment on the
    obligation.
 
        CC -- An obligation rated "CC" is currently highly vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed or similar action has been taken, but payments on
    this obligation are being continued.
 
        D -- An obligation rated "D" is in payment default. The "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the applicable grace period has not expired, unless S&P believes
    that such payments will be made during such grace period. The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally will be evidenced by many of
the characteristics cited above but to a lesser degree. Earnings trends and
coverage ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without
a sales charge and Class B shares (the "Class B shares") and Class C shares (the
"Class C shares") of the Multiple Class Funds which offer such classes are sold
at net asset value subject to a contingent deferred sales charge payable upon
certain redemptions. Class B shares of AIM DOLLAR FUND, however, may be acquired
only by an exchange of shares of another AIM Fund. These contingent deferred
sales charges are described under the caption "How to Redeem Shares -- Multiple
Distribution System." Securities dealers and other persons entitled to receive
compensation for selling or servicing shares of a Multiple Class Fund may
receive different compensation for selling or servicing one particular class of
shares over another class in the same Multiple Class Fund. Factors an investor
should consider prior to purchasing Class A, Class B or Class C shares (or, if
applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For
information on purchasing any of the AIM Funds and to receive a prospectus,
please call (800) 347-4246. As described below, the sales charge otherwise
applicable to a purchase of shares of a fund may be reduced if certain
conditions are met. In order to take advantage of a reduced sales charge, the
prospective investor or his dealer must advise AIM Distributors that the
conditions for obtaining a reduced sales charge have been met. Net asset value
is determined in the manner described under the caption "Determination of Net
Asset Value."

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed

<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6

                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9
<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25

                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MID CAP GROWTH FUND,

INFORMATION.  Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

<TABLE>
<S>                            <C>                                               <C>
  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The
                               distributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors      An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"), Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."
 
                               Class B shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such shares were purchased. Class B shares redeemed after six years from the

                                  (Continued)

<TABLE>
<S>                            <C>                                               <C>
                               date such shares were purchased will not be subject to any contingent deferred sales charge. See "How
                               to Redeem Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve its investment objective. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the Portfolio's
                               portfolio holdings. The Portfolio's policy of concentrating its investments in companies that design,
                               develop or provide products and services significant to a country's infrastructure may cause the
                               Fund's net asset value to fluctuate more than if it invested in a greater number of industries.
 
                               The Portfolio may invest in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
 
                               The Portfolio may engage in certain foreign currency, options and futures transactions to attempt to
                               hedge against the overall level of investment and currency risk associated with its present or
                               planned investments. Such transactions involve certain risks and transaction costs.
 
                               The Portfolio may invest up to 20%, of its total assets in below investment grade debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

(1)  THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
     COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
     shareholders may pay more than the economic equivalent of the maximum
     front-end sales charge permitted by the National Association of Securities
     Dealers, Inc. rules regarding investment companies.
 
(2)  Sales charge waivers are available for Class A and Class B shares, and
     reduced sales charge purchase plans are available for Class A shares. The
     maximum 5% contingent deferred sales charge on Class B shares applies to
     redemptions during the first year after purchase. The charge generally
     declines by 1% annually thereafter, reaching zero after six years. See
     "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
     Sales Charges."
 
(3)  Expenses are based on the Fund's fiscal year ended October 31, 1997
     restated to reflect AIM's undertaking to limit the Fund's expenses
     (exclusive of brokerage commissions, taxes, interest and extraordinary
     expenses) to the annual rate of 2.00% and 2.50% of the average daily net
     assets of the Fund's Class A and Class B shares, respectively. Without
     reimbursements and waivers, "Other Expenses" and "Total Fund Operating
     Expenses" would have been 0.60% and 2.08%, respectively, for Class A shares
     and 0.60% and 2.58%, respectively, for Class B shares of the Fund. "Other
     expenses" include custody, transfer agency, legal, audit and other
     operating expenses. See "Management" herein and the Statement of Additional
     Information for more information.
     The Board of Trustees of the Trust believes that the aggregate per share
     expenses of the Fund and the Portfolio will be approximately equal to the
     expenses the Fund would incur if its assets were invested directly in the
     type of securities being held by the Portfolio.
(4)  Assumes payment of maximum sales charge by the investor.
(5)  Assumes deduction of the applicable contingent deferred sales charge.
(6)  THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
     EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
     DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
     table and the assumption in the Hypothetical Example of a 5% annual return
     are required by regulation of the SEC applicable to all mutual funds. The
     5% annual return is not a prediction of and does not represent the Fund's
     or the Portfolio's projected or actual performance.
(7)  For Class B shares, this number reflects the conversion to Class A shares
     eight years following the end of the calendar month in which a purchase was
     made.

The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.

PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
INFRASTRUCTURE FUND
    
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that design, develop or provide products and services significant to a country's
infrastructure. The Portfolio's investment objective is identical to that of the
Fund. There can be no assurance that the Fund or Portfolio will achieve its
investment objective.
    
 
   
At least 65% of the Portfolio's total assets normally will be invested in common
and preferred stocks and warrants to acquire such securities issued by
infrastructure companies. An "infrastructure" company is an entity in which (i)
at least 50% of either the revenues or earnings was derived from infrastructure
activities, or (ii) at least 50% of the assets was devoted to such activities,
based on the company's most recent fiscal year. The remainder of the Portfolio's
assets may be invested in debt securities issued by infrastructure companies
and/or equity and debt securities of companies outside of the infrastructure
industries, which, in the opinion of the Sub-adviser, stand to benefit from
developments in the infrastructure industries.
    
 
GLOBAL INFRASTRUCTURE INDUSTRIES INVESTMENT. Examples of infrastructure
companies include those engaged in designing, developing or providing the
following products and services: electricity production; oil, gas, and coal
exploration, development, production and distribution; water supply, including
water treatment facilities; nuclear power and other alternative energy sources;
transportation, including the construction or operation of transportation
systems; steel, concrete, or similar types of products; communications equipment
and services (including equipment and services for both data and voice
transmission); mobile communications and cellular radio/paging; emerging
technologies combining telephone, television and/or computer systems; and other
products and services, which, in the Sub-adviser's judgment, constitute services
significant to the development of a country's infrastructure.
 
The Sub-adviser believes that a country's infrastructure is one key to the
long-term success of that country's economy. The Sub-adviser believes that
adequate energy, transportation, water, and communications systems are essential
elements for long-term economic growth. The Sub-adviser believes that many
developing nations, especially in Asia and Latin America, plan to make
significant expenditures to the development of their infrastructure in the
coming years, which is expected to facilitate increased levels of services and
manufactured goods.
 
In the developed countries of North America, Europe, Japan and the Pacific Rim,
the Sub-adviser expects that the replacement and upgrade of transportation and
communications systems should stimulate growth in the infrastructure industries
of those countries. In addition, in the Sub-adviser's view, deregulation of
telecommunications and electric and gas utilities in many countries is promoting
significant changes in these industries.
 
   
The Sub-adviser believes that strong economic growth in developing countries and
infrastructure replacement, upgrade, and deregulation in more developed
countries provide an environment for favorable investment opportunities in
infrastructure companies worldwide. In addition, the long-term growth rates of
certain foreign countries' economies may be substantially higher than the
long-term growth rate of the U.S. economy. An integral aspect of certain foreign
countries' economies may be the development or improvement of their
infrastructure.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the
infrastructure industries are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets

                         AIM GLOBAL INFRASTRUCTURE FUND
   
located throughout the world and the substantial global resources of AMVESCAP
PLC in attempting to identify those countries and companies then providing the
greatest potential for long-term capital appreciation. In this fashion, the
Sub-adviser seeks to enable shareholders to capitalize on the substantial
investment opportunities and the potential for long-term growth of capital
presented by the global infrastructure industry represented in the Portfolio.
    
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 50% of the Portfolio's total assets.
    
 
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
                               Prospectus Page 8
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Portfolio's sale of securities together with
its commitment (for which the Portfolio may receive a fee) to purchase similar,
but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolio to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other collateral as permitted by the Portfolio's investment program and
regulatory agencies, and as approved by the Board. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write
    
 
                               Prospectus Page 9
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
call options on such futures contracts to protect against a general stock market
decline or a decline in a specific market sector that could affect adversely the
Portfolio's holdings. The Portfolio also may purchase stock index futures
contracts and purchase call options or write put options on such contracts to
hedge against a general stock market or market sector advance and thereby
attempt to lessen the cost of future securities acquisitions. The Portfolio may
use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval. The investment policies of the Fund are identical to the
investment policies of the Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts," respectively in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because the Fund will invest only in the Portfolio, the Fund's shareholders will
acquire only an indirect interest in the investments of the Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as
    
 
                               Prospectus Page 10

                         AIM GLOBAL INFRASTRUCTURE FUND
   
the Fund and may charge different sales commissions. Therefore, investors in the
Fund may experience different returns than investors in another investment
company that invests exclusively in the Portfolio. As of the date of this
Prospectus, the Fund is the only institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities positions. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the infrastructure industries,
an investment in it may be more volatile than that of other investment companies
that do not concentrate their investments in such a manner. Moreover, the value
of the shares of the Fund will be especially susceptible to factors affecting
the infrastructure industries. Accordingly, the Fund should be considered a
complete investment program.
    
 
   
INFRASTRUCTURE INDUSTRIES. Infrastructure industries may be subject to greater
political, environmental and other governmental regulation than many other
industries. The nature of such regulation continues to evolve in both the United
States and foreign countries, and changes in governmental policy and the need
for regulatory approvals may have a material effect on the products and services
offered by companies in the infrastructure industries. Electric, gas, water and
most telecommunications companies in the United States, for example, are subject
to both federal and state regulation affecting permitted rates of return and the
kinds of services that may be offered. Governmental regulation may also hamper
the development of new technologies.
    
 
In addition, many infrastructure companies have historically been subject to the
risks attendant to increases in fuel and other operating costs, high interest
costs on borrowed funds, costs associated with compliance with environmental and
other safety regulations and changes in the regulatory climate. Further,
competition is intense for many infrastructure companies. As a result, many of
these companies may be adversely affected in the future and such companies may
be subject to increased share price volatility. In addition, many companies have
diversified into oil and gas exploration and development, and therefore returns
may be more sensitive to energy prices. Other infrastructure companies, such as
water supply companies, are in a highly fragmented industry due to local
ownership. Generally these companies are mature and are experiencing little or
no growth. Changes in prevailing interest rates may also affect the
Infrastructure Fund's share values because prices of equity and debt securities
of infrastructure companies often tend to increase when interest rates decline
and decrease when interest rates rise.
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less
    
 
                               Prospectus Page 11
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
publicly available information about foreign securities and issuers than is
available about domestic securities and issuers. Foreign companies generally are
not subject to uniform accounting, auditing and financial reporting standards,
practices and requirements comparable to those applicable to domestic companies.
In addition, certain costs attributable to foreign investing, such as custody
charges, are higher than those attributable to domestic investing. Securities of
some foreign companies are less liquid and their prices may be more volatile
than securities of comparable domestic companies. The Portfolio's interest and
dividends from foreign issuers may be subject to non-U.S. withholding taxes,
thereby reducing the Portfolio's net investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 20%, of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition,
 
                               Prospectus Page 12
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
lower quality debt securities tend to be more sensitive to economic conditions
and generally have more volatile prices than higher quality securities. Issuers
of lower quality securities are often highly leveraged and may not have
available to them more traditional methods of financing. For example, during an
economic downturn or a sustained period of rising interest rates, highly
leveraged issuers of lower quality securities may experience financial stress.
During such periods, such issuers may not have sufficient revenues to meet their
interest payment obligations. The issuer's ability to service its debt
obligations may also be adversely affected by specific developments affecting
the issuer, such as the issuer's inability to meet specific projected business
forecasts or the unavailability of additional financing. The risk of loss due to
default by the issuer is significantly greater for the holders of lower quality
securities because such securities are generally unsecured and may be
subordinated to the claims of other creditors of the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if it did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the Portfolio to sell a security at a disadvantageous time, due to the need for
the Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.

<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.

The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the investment objective and policies of the Fund
and the Portfolio and to the general supervision of the Boards. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers to the Fund and the Portfolio include,
but are not limited to, determining the composition of the investment holdings
of the Portfolio and placing orders to buy, sell or hold particular securities.
In addition, AIM and the Sub-adviser provide the following administration
services to the Portfolio and the Fund: furnishing corporate officers and
clerical staff; providing office space, services and equipment; and supervising
all matters relating to the Portfolio's and the Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by its corresponding
Portfolio to AIM and the Sub-adviser. The Portfolio pays AIM a fee, based on the
Portfolio's average daily net assets at the annualized rate of .725% on the
first $500 million, .70% on the next $500 million, .675% on the next $500
million and .65% on all amounts thereafter. Out of its aggregate fees payable by
the Fund and Portfolio, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund and Portfolio. The investment management and administration fees paid by
the Fund and the Portfolio are higher than those paid by most mutual funds. The
Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors or
other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 2.00% and 2.50% of the average daily net assets of the Fund's Class A
and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.

AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
   
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Funds will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of
    
 
                               Prospectus Page 15
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
the Fund directly and through institutions with whom AIM Distributors has
entered into selected dealer agreements. Under the Distribution Agreement for
the Class B shares, AIM Distributors sells Class B shares of the Fund at net
asset value subject to a contingent deferred sales charge established by AIM
Distributors. AIM Distributors is authorized to advance to institutions through
whom Class B shares are sold a sales commission under schedules established by
AIM Distributors. The Distribution Agreement for the Class B shares provides
that AIM Distributors (or its assignee or transferee) will receive 0.75% (of the
total 1.00% payable under the distribution plan applicable to Class B shares) of
the Fund's average daily net assets attributable to Class B shares attributable
to the sales efforts of AIM Distributors. In the event the Class B shares
Distribution Agreement is terminated, AIM Distributors would continue to receive
payments of asset based sales charges in respect of the outstanding Class B
shares attributable to the distribution efforts of AIM Distributors; provided,
however, that a complete termination of the Class B shares master distribution
plan (as defined in the plan) would terminate all payments to AIM Distributors.
Termination of the Class B shares distribution plan or Distribution Agreement
does not affect the obligation of Class B shareholders to pay contingent
deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Company has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.

<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of
    
 
                               Prospectus Page 17
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
   
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

a sales charge and Class B shares (the "Class B shares") and Class C shares (the
"Class C shares") of the Multiple Class Funds which offer such classes are sold

applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For
information on purchasing any of the AIM Funds and to receive a prospectus,
please call (800) 347-4246. As described below, the sales charge otherwise
applicable to a purchase of shares of a fund may be reduced if certain

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed

during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6

                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of

<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,
established for tax-qualified group annuities, for contracts purchased on or
before June 30, 1992. AIM Distributors acts as distributor for the AIM Funds
which represent a range of different investment objectives and policies. As set
forth under the caption "Terms and Conditions of Purchase of the AIM Funds --
Sales Charges and Dealer Concessions," shares of certain of the AIM Funds,
including the Class A shares of the Multiple Class Funds, listed below and
referred to herein as the "Load Funds," are sold at a public offering price that
includes a maximum sales charge of 5.50% or 4.75% of the public offering price
of such shares; Class A shares (or shares which normally involve the payment of
initial sales charges) of certain of the AIM Funds, listed below and referred to
herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16
<PAGE>
                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25

                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MID CAP GROWTH FUND,

INFORMATION.  Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

The Fund and the Portfolio:    The Fund is a diversified series of the Trust. The Portfolio is a diversified series of the Global
                               Investment Portfolio.
 
Investment Objective:          The Fund seeks long-term capital growth.
 
Principal Investments:         The Fund invests all of its investable assets in the Portfolio, which, in turn, invests primarily in
                               equity securities of companies throughout the world that own, explore or develop natural resources
                               and other basic commodities or supply goods and services to such companies.
 
Investment Managers:           The Portfolio is managed by A I M Advisors, Inc. ("AIM") and is sub-advised and sub-administered by
                               INVESCO (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or administrative services to institutional, corporate
                               and individual clients around the world. AIM and the Sub-adviser are both indirect wholly owned
                               subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its subsidiaries are an independent investment
                               management group that has a significant presence in the institutional and retail segment of the
                               investment management industry in North America and Europe, and a growing presence in Asia. AIM was
                               organized in 1976 and, together with its subsidiaries, currently advises approximately 90 investment
                               company portfolios.
 
Purchasing Shares:             Investors may select Class A or Class B shares of the Fund which are offered by this Prospectus at an
                               offering price that reflects differing sales charges and expense levels. See "Terms and Conditions of
                               Purchase of the AIM Funds -- Sales Charges and Dealer Concessions." Pursuant to a separate
                               prospectus, the Fund also offers Advisor Class shares, which represent interests in the Fund. The
                               Advisor Class shares have different distribution arrangements.

                                  (Continued)

<TABLE>
<S>                            <C>                                               <C>
  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The dis-
                               tributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors:     An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."
 
                               Class B shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such shares were purchased. Class B shares redeemed after six years from the date such
                               shares were purchased will not be subject to any contingent

<TABLE>
<S>                            <C>                                               <C>
                               deferred sales charge. See "How to Redeem Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve its investment objective. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the Portfolio's
                               portfolio holdings. The Portfolio's policy of concentrating its investments in companies in the
                               natural resources industries may cause the Fund's net asset value to fluctuate more than if it
                               invested in a greater number of industries.
 
                               The Portfolio may invest in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
 
                               The Portfolio may engage in certain foreign currency, options and futures transactions to attempt to
                               hedge against the overall level of investment and currency risk associated with its present or
                               planned investments. Such transactions involve certain risks and transaction costs.
 
                               The Portfolio may invest up to 20%, of its total assets in below investment grade debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

(1)  THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
     COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
     shareholders may pay more than the economic equivalent of the maximum
     front-end sales charge permitted by the National Association of Securities
     Dealers, Inc. rules regarding investment companies.
 
(2)  Sales charge waivers are available for Class A and Class B shares, and
     reduced sales charge purchase plans are available for Class A shares. The
     maximum 5% contingent deferred sales charge on Class B shares applies to
     redemptions during the first year after purchase. The charge generally
     declines by 1% annually thereafter, reaching zero after six years. See
     "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
     Sales Charges."
 
(3)  Expenses are based on the Fund's fiscal year ended October 31, 1997
     restated to reflect AIM's undertaking to limit the Fund's expenses
     (exclusive of brokerage commissions, taxes, interest and extraordinary
     expenses) to the annual rate of 2.00% and 2.50% of the average daily net
     assets of the Fund's Class A and Class B shares, respectively. Without
     reimbursements and waivers, "Other Expenses" and "Total Fund Operating
     Expenses" would have been 0.65% and 2.13%, respectively, for Class A shares
     and 0.65% and 2.63%, respectively, for Class B shares of the Fund. "Other
     expenses" include custody, transfer agency, legal, audit and other
     operating expenses. See "Management" herein and the Statement of Additional
     Information for more information.
     The Board of Trustees of the Trust believes that the aggregate per share
     expenses of the Fund, and the Portfolio will be approximately equal to the
     expenses the Fund would incur if its assets were invested directly in the
     type of securities being held by the Portfolio.
(4)  Assumes payment of maximum sales charge by the investor.
(5)  Assumes deduction of the applicable contingent deferred sales charge.
(6)  THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
     EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
     DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
     table and the assumption in the Hypothetical Example of a 5% annual return
     are required by regulation of the SEC applicable to all mutual funds. The
     5% annual return is not a prediction of and does not represent the Fund's
     or the Portfolio's projected or actual performance.
(7)  For Class B shares, this number reflects the conversion to Class A shares
     eight years following the end of the calendar month in which a purchase was
     made.

PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that own, explore or develop natural resources and other basic commodities or
supply goods and services to such companies. The Portfolio's investment
objective is identical to that of the Fund. There can be no assurance that the
Fund or Portfolio will achieve its investment objective.
    
 
   
At least 65% of the Portfolio's total assets will normally be invested in common
stock and preferred stock, and warrants to acquire such securities, issued by
natural resource companies. A "natural resource" company is an entity in which
(i) at least 50% of either the revenues or earnings was derived from natural
resource activities, or (ii) at least 50% of the assets was devoted to such
activities, based upon the company's most recent fiscal year. The remainder of
the Portfolio's assets may be invested in debt securities issued by natural
resource companies and/or equity and debt securities of companies outside of the
natural resource industries, which, in the opinion of the Sub-adviser, stand to
benefit from developments in the natural resource industries.
    
 
GLOBAL RESOURCE INDUSTRIES INVESTMENT. Examples of natural resource companies
include those which own, explore or develop: energy sources (such as oil, gas
and coal); ferrous and non-ferrous metals (such as iron, aluminum, copper,
nickel, zinc and lead), strategic metals (such as uranium and titanium) and
precious metals (such as gold, silver and platinum); chemicals; forest products
(such as timber, coated and uncoated tree sheet, pulp and newsprint); other
basic commodities (such as foodstuffs); refined products (such as chemicals and
steel) and service companies that sell to these producers and refiners; and
other products and services, which, in the Sub-adviser's opinion are significant
to the ownership and development of natural resources and other basic
commodities.
 
The Sub-adviser believes that the liberalization of formerly socialist economies
will bring about dramatic changes in both the supply and demand for natural
resources. In addition, rapid industrialization in developing countries of Asia
and Latin America is generating new demands for industrial materials that are
affecting world commodities markets. The Sub-adviser believes these changes are
likely to create investment opportunities that benefit from new sources of
supply and/or from changes in commodities prices.
 
   
The Sub-adviser also believes that investments in natural resource industries
offer an opportunity to protect wealth against the capital-eroding effects of
inflation. During periods of accelerating inflation or currency uncertainty,
worldwide investment demand for natural resources, particularly precious metals,
tends to increase, and during periods of disinflation or currency stability, it
tends to decrease. The Sub-adviser believes that rising commodity prices and
increasing worldwide industrial production may favorably affect share prices of
natural resource companies, and investments in such companies can offer
excellent opportunities to offset the effects of inflation.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the natural
resources industries are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets located throughout the world and the substantial global
resources of AMVESCAP PLC in attempting to identify those countries and
companies then providing the greatest potential for long-term capital
appreciation. In this fashion, the Sub-adviser seeks to enable shareholders to
capitalize on the substantial investment opportunities and the potential for
long-term growth of capital presented by the global natural resources industries
represented in the Portfolio.
    
 
                               Prospectus Page 7
<PAGE>
                           AIM GLOBAL RESOURCES FUND
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 50% of the Portfolio's total assets.
    
 
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
 
In assessing companies for the Resources Portfolio, the Sub-adviser will also
evaluate, among other factors, their capabilities for expanded exploration and
production, superior exploration programs and production techniques and
facilities, current inventories, expected production and demand levels and the
potential to accumulate new resources.
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
                               Prospectus Page 8
<PAGE>
                           AIM GLOBAL RESOURCES FUND
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Portfolio's sale of securities together with
its commitment (for which the Portfolio may receive a fee) to purchase similar,
but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolios to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other collateral as permitted by the Portfolio's investment program and
regulatory agencies, and as approved by the Board. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write
    
 
                               Prospectus Page 9
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
call options on such futures contracts to protect against a general stock market
decline or a decline in a specific market sector that could affect adversely the
Portfolio's holdings. The Portfolio also may purchase stock index futures
contracts and purchase call options or write put options on such contracts to
hedge against a general stock market or market sector advance and thereby
attempt to lessen the cost of future securities acquisitions. The Portfolio may
use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of that Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts," respectively, in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because the Fund will invest only in the Portfolio, the Fund's shareholders will
acquire only an indirect interest in the investments of the Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may
    
 
                               Prospectus Page 10
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
experience different returns than investors in another investment company that
invests exclusively in the Portfolio. As of the date of this Prospectus, the
Fund is the only institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the natural resources
industries, an investment in it may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
Moreover, the value of the shares of the Fund will be especially susceptible to
factors affecting the natural resources industries in which it focuses.
Accordingly, the Fund should not be considered a complete investment program.
    
 
   
NATURAL RESOURCES INDUSTRIES. Natural resource industries may be subject to
greater political, environmental and other governmental regulation than many
other industries. The nature of such regulation continues to evolve in both the
United States and foreign countries, and changes in governmental policies and
the need for regulatory approvals may have a material effect on the products and
services offered by companies in the natural resource industries. For example,
the exploration, development and distribution of coal, oil and gas in the United
States are subject to significant federal and state regulation, which may affect
rates of return on such investments and the kinds of services that may be
offered. Governmental regulation may also hamper the development of new
technologies.
    
 
In addition, many natural resource companies historically have been subject to
significant costs associated with compliance with environmental and other safety
regulations. Further, competition is intense for many natural resource
companies. As a result, many of these companies may be adversely affected in the
future and the value of the securities issued by such companies may be subject
to increased share price volatility. Such companies may also be subject to
irregular fluctuations in earnings due to changes in the availability of money,
the level of interest rates, and other factors.
 
The value of securities of natural resource companies will fluctuate in response
to market conditions for the particular natural resources with which the issuers
are involved. The price of natural resources will fluctuate due to changes in
worldwide levels of inventory, and changes, perceived or actual, in production
and consumption. With respect to precious metals, such price fluctuations may be
substantial over short periods of time. In addition, the value of natural
resources may fluctuate directly with respect to various stages of the
inflationary cycle and perceived inflationary trends and are subject to numerous
factors, including national and international politics.
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
    
 
                               Prospectus Page 11
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Portfolio's interest and dividends from foreign issuers may be
subject to non-U.S. withholding taxes, thereby reducing the Portfolio's net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 20%, of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
 
                               Prospectus Page 12
<PAGE>
                           AIM GLOBAL RESOURCES FUND
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if they did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the

                           AIM GLOBAL RESOURCES FUND
Portfolio to sell a security at a disadvantageous time, due to the need for the
Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.

                                   MANAGEMENT
    
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administrative services agreement with AIM, the investment
sub-advisory and sub-administration agreement between AIM and the Sub-adviser,
the agreements with AIM Distributors regarding distribution of the Fund's
shares, the custody agreement and the transfer agency agreement. The day-to-day
operations of the Fund and the Portfolio are delegated to the officers of the
Trust and the Portfolio, subject always to the investment objective and policies
of the Fund and the Portfolio and to the general supervision of the Boards. See
"Trustees and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers to the Fund and the Portfolio include,
but are not limited to, determining the composition of the investment holdings
of the Portfolio and placing orders to buy, sell or hold particular securities.
In addition, AIM and the Sub-adviser provide the following administration
services to the Portfolio and the Fund: furnishing corporate officers and
clerical staff; providing office space, services and equipment; and supervising
all matters relating to the Portfolio's and the Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by its corresponding
Portfolio to AIM and the Sub-adviser. The Portfolio pays AIM a fee, based on the
Portfolio's average daily net assets at the annualized rate of .725% on the
first $500 million, .70% on the next $500 million, .675% on the next $500
million and .65% on all amounts thereafter. Out of its aggregate fees payable by
the Fund and the Portfolio, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund and the Portfolio. The investment management and administration fees paid
by the Fund and the Portfolio are higher than those paid by most mutual funds.
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 2.00% and 2.50% of the average daily net assets of the Fund's Class A
and Class B shares, respectively.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund).

Each of these funds, including the Fund and the Portfolio, pays an amount based
upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administrative services agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administrative agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices, including investment offices in Atlanta, Boston,
Dallas, Denver, Louisville, Miami, Portland (Oregon), Frankfurt, Hong Kong,
London, Singapore, Sydney, Tokyo and Toronto. In managing the Portfolio, the
Sub-adviser employs a team approach, taking advantage of its investment
resources around the world.
    
 
   
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Funds will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM
    
 
                               Prospectus Page 15
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
Distributors sells Class B shares of the Fund at net asset value subject to a
contingent deferred sales charge established by AIM Distributors. AIM
Distributors is authorized to advance to institutions through whom Class B
shares are sold a sales commission under schedules established by AIM
Distributors. The Distribution Agreement for the Class B shares provides that
AIM Distributors (or its assignee or transferee) will receive 0.75% (of the
total 1.00% payable under the distribution plan applicable to Class B shares) of
the Fund's average daily net assets attributable to Class B shares attributable
to the sales efforts of AIM Distributors. In the event the Class B shares
Distribution Agreement is terminated, AIM Distributors would continue to receive
payments of asset based sales charges in respect of the outstanding Class B
shares attributable to the distribution efforts of AIM Distributors; provided,
however, that a complete termination of the Class B shares master distribution
plan (as defined in the plan) would terminate all payments to AIM Distributors.
Termination of the Class B shares distribution plan or Distribution Agreement
does not affect the obligation of Class B shareholders to pay contingent
deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Company has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional
    
 
                               Prospectus Page 16

information and reports for other than existing shareholders, overhead,
preparation and distribution of advertising material and sales literature,
expense of organizing and conducting sales seminars, supplemental payments to
dealers and other institutions such as asset-based sales charges or as payments
of service fees under shareholder service arrangements, and the cost of
administering the Plans. These amounts payable by the Fund under the Plans need
not be directly related to the expenses actually incurred by AIM Distributors on
behalf of the Fund. Thus, even if AIM Distributors' actual expenses exceed the
fee payable to AIM Distributors thereunder at any given time, the Trust will not
be obligated to pay more than that fee, and if AIM Distributors' expenses are
less than the fee it receives, AIM Distributors will retain the full amount of
the fee. Payments pursuant to the Plans are subject to any applicable
limitations imposed by rules of the National Association of Securities Dealers,
Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
liabilities of AIM Investment Funds, Inc., a Maryland corporation. The Fund
constitutes one of the thirteen separate and distinct series or portfolios of
the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other shares do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a

meeting of shareholders solely for the purpose of removing one or more Trustees
when requested in writing to do so by shareholders holding 10% of the Trust's
outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund when issued are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
   
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional

payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed

<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6

                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of

                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone

efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'

- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE

                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales

charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25
<PAGE>
                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MID CAP GROWTH FUND,

INFORMATION.  Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

The Fund:                      The Fund is a diversified series of the Trust.
 
Investment Objective:          The Fund seeks long-term growth of capital
 
Principal Investments:         The  Fund invests  primarily in equity  securities of companies  throughout the world  engaged in the
                               development, manufacture or sale of telecommunications services or equipment.

                                    SUMMARY
    
- ------------------------------------------------------------
 
   
<TABLE>
<S>                            <C>                                               <C>
  Class A Shares:              Shares are offered at net asset value plus any applicable initial sales charge.
  Class B Shares:              Shares  are offered at net asset  value without an initial sales  charge, and are subject to deferred
                               sales charge of  5% on  certain redemptions  made within six  years from  the date  such shares  were
                               purchased.  Class B shares automatically convert to Class  A shares of the Fund eight years following
                               the end of the  calendar month in which  a purchase was  made. Class B shares  are subject to  higher
                               expenses than Class A shares.
                               Initial  investments in any class of shares must be  at least $500 and additional investments must be
                               at least  $50. The  minimum initial  investment  is modified  for investments  through  tax-qualified
                               retirement  plans and  accounts initially  established with  an Automatic  Investment Plan.  The dis-
                               tributor of the  Fund's shares  is A  I M  Distributors, Inc.  ("AIM Distributors"),  P.O. Box  4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
Suitability for Investors:     An  investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are  expected
                               to  be held, and other circumstances. Investors  should consider whether, during the anticipated life
                               of their investment  in the Fund,  the accumulated  distribution fees and  any applicable  contingent
                               deferred  sales charges on Class  B shares prior to  conversion would be less  than the initial sales
                               charge and accumulated distribution fees on  Class A shares purchased at  the same time, and to  what
                               extent  such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination,  the table under the  caption "Table of Fees  and Expenses" sets  forth
                               examples  of the charges  applicable to each  class of shares.  Class A shares  will normally be more
                               beneficial than Class B shares  to the investor who qualifies  for reduced initial sales charges,  as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
Exchange Privilege:            The  Fund is among those mutual funds distributed  by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in  The
                               AIM  Family of  Funds in the  manner and subject  to the policies  and charges set  forth herein. See
                               "Exchange Privilege."
Redeeming Shares:              Class A shareholders of the Fund may  redeem all or a portion of  their shares at net asset value  on
                               any  business day, generally  without charge. A contingent  deferred sales charge of  1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How  to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

                               Class  B shareholders of the Fund may  redeem all or a portion of  their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years  from
                               the  date such  shares were purchased.  Class B shares  redeemed after  six years from  the date such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
Distributions:                 The Fund currently  declares and  pays dividends from  net investment  income, if any,  on an  annual
                               basis.  The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales  charge
                               in  the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset value
                               will fluctuate, reflecting fluctuations  in the market  value of its  portfolio holdings. The  Fund's
                               policy  of concentrating  its investments  in companies  in its  particular industries  may cause the
                               Fund's net asset value to fluctuate more than if it invested in a greater number of industries.
                               The Fund may invest in foreign securities.  Investments in foreign securities involve risks  relating
                               to  political and economic developments  abroad and the differences  between the regulations to which
                               U.S. and foreign  issuers are  subject. Individual  foreign economies  also may  differ favorably  or
                               unfavorably  from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid  and their prices more volatile  than those of securities of  comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against  the overall  level of investment  and currency risk  associated with its  present or planned
                               investments. Such transactions involve certain risks and transaction costs.
                               The Fund  may invest  up  to 5%  of  its total  assets in  below  investment grade  debt  securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

- --------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUNDS. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Funds' fiscal year ended October 31, 1997. "Other
    Expenses" include custody, transfer agency, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the Hypothetical Example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

PERFORMANCE All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term growth of capital. It seeks its
objective by investing primarily in equity securities of companies throughout
the world engaged in the development, manufacture or sale of telecommunications
services or equipment. There can be no assurance that the Fund will achieve its
investment objective.
    
 
   
At least 65% of the Fund's total assets normally will be invested in common and
preferred stocks and warrants to acquire such securities issued by
telecommunications companies. A "telecommunications" company is an entity in
which (i) at least 50% of either its revenues or earnings was derived from
telecommunications activities, or (ii) at least 50% of its assets was devoted to
telecommunications activities, based on the company's most recent fiscal year.
The remainder of the assets of the Fund may be invested in debt securities
issued by telecommunications companies and/or equity and debt securities of
companies outside of the telecommunications industry which, in the opinion of
the Sub-adviser, stand to benefit from developments in the telecommunications
industries.
    
 
   
GLOBAL TELECOMMUNICATIONS INDUSTRIES INVESTMENT. Telecommunications companies
cover a variety of sectors, ranging from companies concentrating on established
technologies to those primarily engaged in emerging or developing technologies.
The characteristics of companies focusing on the same technology will vary among
countries depending upon the extent to which the technology is established in
the particular country. The Sub-adviser will allocate the Fund's investments
among these sectors depending upon its assessment of their relative long-term
growth potential.
    
 
Examples of telecommunications companies include those engaged in designing,
developing or providing the following products and services: communications
equipment and services (including equipment and services for both data and voice
transmission); electronic components and equipment; broadcasting (including
television and radio, satellite, microwave and cable television and
narrowcasting); computer equipment, mobile communications and cellular
radio/paging; electronic mail; local and wide area networking and linkage of
word and data processing systems; publishing and information systems; videotext
and teletext; and emerging technologies combining telephone, television and/or
computer systems.
 
   
The Sub-adviser believes that there are opportunities for continued growth in
demand for components, products, media and systems to collect, store, retrieve,
transmit, process, distribute, record, reproduce and use information. The
pervasive societal impact of communications and information technologies has
been accelerated by the lower costs and higher efficiencies that result from the
blending of computers with telecommunications systems. Accordingly, companies
engaged in the production of methods for using electronic and, potentially,
video technology to communicate information are expected to be important in the
Fund's portfolio. Older technologies, such as photography and print also may be
represented, however.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Fund expects that, from time
to time, a significant portion of its assets may be invested in the securities
of domestic issuers. The industry represented in the Fund, however, is a global
industry with significant, growing markets outside of the United States. A
sizeable proportion of the companies which comprise the telecommunications
industry are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Fund. The Sub-adviser uses its financial expertise in
markets located throughout the world and the substantial global resources of
AMVESCAP PLC in attempting to identify those countries and companies then
providing the greatest potential for long-term capital appreciation. In this
fashion, the Sub-adviser seeks to enable shareholders to capitalize on the
substantial investment opportunities and the potential for long-term growth of
capital presented by the global industry represented in the Fund.

<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
 
   
The Sub-adviser allocates the Fund's assets among securities of countries and in
currency denominations where opportunities for meeting the Fund's investment
objective are expected to be the most attractive. The Fund may invest
substantially in securities denominated in one or more currencies. Under normal
conditions, the Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 40% of the Fund's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Fund may invest up to 100%
of its total assets in cash (U.S. dollars, foreign currencies or multinational
currency units such as Euros) and/or high quality debt securities or money
market instruments of U.S. or foreign issuers. In addition, for temporary
defensive purposes, most or all of the Fund's investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund adopts a
temporary defensive posture, it will not be invested so as to achieve directly
its investment objective. In addition, pending investment of proceeds from new
sales of Fund shares or to meet its ordinary daily cash needs, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units) and may
invest in foreign or domestic high quality money market instruments. For a full
description of money market instruments, see "Money Market Instruments" in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Fund to participate in privatizations may be limited by local law,
or the terms on which the Fund may be permitted to participate may be less
advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Fund may invest up to 10% of its
total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Fund would
bear its ratable share of that investment company's expenses, including its
advisory and administration fees. At the same time, the Fund would continue to
pay its own management fees and other expenses. AIM and the Sub-adviser will
waive their advisory fees to the extent that the Fund invests in an Affiliated
Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemptions of the
Fund's shares. The Fund also may borrow up to 5% of its total assets for
temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Fund may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Fund's borrowings exceed 5% of its
total assets. Any borrowing by the Fund may cause greater fluctuation in the
value of its shares than would be the case if the Fund did not borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Fund's sale of securities together with its
commitment (for which the Fund may receive a fee) to purchase similar, but not
identical, securities at a future date.

<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least the value of the
borrowed securities, plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral should the borrower fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities or enter into forward commitments only with the
intention of actually receiving or delivering the securities, as the case may
be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery to the Fund. If
the Fund disposes of the right to acquire a when-issued security prior to its
acquisition or disposes of its right to deliver or receive against a forward
commitment, it may incur a gain or loss. At the time the Fund enters into a
transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Fund may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
stock indexes to hedge against overall fluctuations in the securities markets
generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Fund's holdings. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.

OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depositary Receipts," in the "Investment Objectives and
Policies" section of the Statement of Additional Information.
    
 
- --------------------------------------------------------------------------------
 
                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. The Fund's net asset value will fluctuate reflecting fluctuations in
the market value of the Fund's positions. Equity securities, particularly common
stocks, generally represent the most junior position in an issuer's capital
structure, and entitle holders to an interest in the assets of an issuer, if
any, remaining after all more senior claims have been satisfied. The value of
equity securities held by the Fund will fluctuate in response to general market
and economic developments, as well as developments affecting the particular
issuers of such securities. In addition, the value of debt securities held by
the Fund generally will fluctuate with changes in the perceived creditworthiness
of the issuers of such securities and interest rates.
    
 
   
Because the Fund focuses its investments on particular industries, an investment
in the Fund may be more volatile than that of other investment companies that do
not concentrate their investments in such a manner. Moreover, the value of the
shares of the Fund will be especially susceptible to factors affecting the
industries in which it focuses. Accordingly, the Fund should not be considered a
complete investment program.
    
 
   
TELECOMMUNICATIONS INDUSTRIES. Telecommunications industries may be subject to
greater governmental regulation than many other industries and changes in
governmental policy and the need for regulatory approvals may have a material
effect on the products and services offered by companies in the
telecommunications industries. Telephone operating companies in the United
States, for example, are subject to both federal and state regulation affecting
permitted rates of return and the kinds of services that may be offered. Certain
types of companies in the telecommunications industries are engaged in fierce
competition for market share that could result in increased share price
volatility.
    
 
                               Prospectus Page 10
<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's interest and dividends from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing the Fund's net investment
income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the Fund's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Fund may invest in issuers domiciled in "emerging markets." Investing in
emerging market countries involves risks in addition to those risks involved in
foreign investing. Many emerging market countries have experienced high rates of
inflation for many years. In addition, emerging markets generally are dependent
heavily upon international trade and, accordingly, have been and continue to be
affected adversely by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. The securities markets of emerging
market countries are substantially smaller, less developed, less liquid and more
volatile than the securities markets of the developed countries. In addition,
issuers in emerging markets typically are subject to a greater degree of change
in earnings and business prospects than issuers in developed countries.
    
 
   
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Fund may invest up to 5% of its total assets
in below investment grade debt securities, that is, rated below BBB by Standard
& Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa by
Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Fund will not invest in debt securities that
are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
                               Prospectus Page 11
<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Fund. If an issuer exercises these provisions in a declining
interest rate market, the Fund may have to replace the security with a lower
yielding security, resulting in a decreased return for investors. In addition,
the Fund may have difficulty disposing of lower quality securities because they
may have a thin trading market. There may be no established retail secondary
market for many of these securities, and the Fund anticipates that such
securities could be sold only to a limited number of dealers or institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on market prices of such instruments and may make it more difficult for the Fund
to obtain accurate market quotations for purposes of valuing the Fund's
portfolio investments. The Fund may also acquire lower quality debt securities
during an initial underwriting or which are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Fund may also incur additional expenses to the extent it
is required to seek recovery upon a default in the payment of principal or
interest on portfolio holdings, and the Fund may have limited legal recourse in
the event of a default.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Fund to achieve
capital appreciation substantially exceeding the appreciation the Fund would
realize if it did not make such investments. However, in order to attempt to
limit investment risk, the Fund will invest no more than 5% of its total assets
in Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets or in the appropriate
market sector and movements in interest rates and currency markets; (2)
imperfect correlation, or even no correlation, between movements in the price of
options, forward contracts, futures contracts or options thereon and movements
in the price of the currency or security hedged or used for cover; (3) the fact
that skills and techniques needed to trade options, futures contracts and
options thereon or to use forward currency contracts are different from those
needed to select the securities in which the Fund invests; (4) lack of assurance
that a liquid secondary market will exist for any particular option, futures
contract or option thereon at any particular time; (5) the possible loss of
principal under certain conditions; and (6) the possible

                       AIM GLOBAL TELECOMMUNICATIONS FUND
   
inability of the Fund to purchase or sell a portfolio security at a time when it
would otherwise be favorable for it to do so, or the possible need for the Fund
to sell a security at a disadvantageous time, due to the need for the Fund to
maintain "cover" or to set aside securities in connection with hedging
transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Fund's portfolio normally will include
securities of established suppliers of traditional products and services, the
Fund may invest in smaller companies which can benefit from the development of
new products and services. These smaller companies may present greater
opportunities for capital appreciation, but may also involve greater risks than
large, established issuers. Such smaller companies may have limited product
lines, markets or financial resources, and their securities may trade less
frequently and in more limited volume than the securities of larger, more
established companies. As a result, the prices of the securities of such smaller
companies may fluctuate to a greater degree than the prices of the securities of
other issuers.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust and persons or companies furnishing services to the Fund on
the other, including the investment management and administration agreement with
AIM, the investment sub-advisory and sub-administration agreement between AIM
and the Sub-adviser, the agreements with AIM Distributors regarding distribution
of the Fund's shares, the custody agreement and the transfer agency agreement.
The day-to-day operations of the Fund are delegated to the officers of the
Trust, subject always to the investment objective and policies of the Fund and
to the general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers include, but are not limited to,
determining the composition of the investment portfolio of the Fund and placing
orders to buy, sell or hold particular securities. In addition, AIM and the
Sub-adviser provide the following administration services to the Fund:
furnishing corporate officers and clerical staff; providing office space,
services and equipment; and supervising all matters relating to the Fund's
operation.
    
 
   
For investment management and administration services provided to the Fund, the
Fund pays AIM a fee computed daily and paid monthly based on the Fund's average
daily net assets at the annualized rate of .975% on the first $500 million, .95%
on the next $500 million, .925% on the next $500 million and .90% on amounts
thereafter. Out of the aggregate fees payable by the Fund, AIM pays the
Sub-adviser sub-advisory and sub-administration fees equal to 40% of the
aggregate fees AIM receives from the Fund. The investment management and
administration fees paid by the Fund are higher than those paid by most mutual
funds.
    
 
   
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 2.00% and 2.50% of the average daily net assets of the Fund's Class A
and Class B shares, respectively. The Sub-adviser also serves as the Fund's
pricing and accounting agent. For these services the Sub-adviser receives a fee
consisting of 0.03% of the first $5 billion of assets, and 0.02% of the assets
in excess of $5 billion, of the AIM Funds that are sub-advised by the
Sub-adviser (other than AIM Eastern Europe Fund). Each of these funds, including
the Fund, pays an amount based upon its relative net assets.

AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration services agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
   
The investment professional primarily responsible for the portfolio management
of the Fund is as follows:

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions may be executed through affiliates of
AIM or the Sub-adviser. High portfolio turnover (over 100%) involves
correspondingly greater brokerage commissions and other transaction costs that
the Funds will bear directly and could result in the realization of net capital
gains which would be taxable when distributed to shareholders. See "Dividends,
Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors.

<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
   
The Distribution Agreement for the Class B shares provides that AIM Distributors
(or its assignee or transferee) will receive 0.75% (of the total 1.00% payable
under the distribution plan applicable to Class B shares) of the Fund's average
daily net assets attributable to Class B shares attributable to the sales
efforts of AIM Distributors. In the event the Class B shares Distribution
Agreement is terminated, AIM Distributors would continue to receive payments of
asset based sales charges in respect of the outstanding Class B shares
attributable to the distribution efforts of AIM Distributors; provided, however,
that a complete termination of the Class B shares master distribution plan (as
defined in the plan) would terminate all payments to AIM Distributors.
Termination of the Class B shares distribution plan or Distribution Agreement
does not affect the obligation of Class B shareholders to pay contingent
deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Company has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund. Any amounts not paid as a service fee would
constitute an asset-based sales charge. Amounts paid in accordance with the
Class B Plan with respect to the Fund may be used to finance any activity
primarily intended to result in the sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other

                       AIM GLOBAL TELECOMMUNICATIONS FUND
   
institutions such as asset-based sales charges or as payments of service fees
under shareholder service arrangements, and the cost of administering the Plans.
These amounts payable by the Fund under the Plans need not be directly related
to the expenses actually incurred by AIM Distributors on behalf of the Fund.
Thus, even if AIM Distributors' actual expenses exceed the fee payable to AIM
Distributors thereunder at any given time, the Trust will not be obligated to
pay more than that fee, and if AIM Distributors' expenses are less than the fee
it receives, AIM Distributors will retain the full amount of the fee. Payments
pursuant to the Plans are subject to any applicable limitations imposed by rules
of the National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998 . On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may continue to establish other
funds, each corresponding to a distinct investment portfolio and a distinct
series of the Trust's shares of beneficial interest. Shares of each fund are
entitled to one vote per share (with proportional voting for fractional shares)
and are freely transferable. Shareholders have no preemptive rights. Other than
the automatic conversion of Class B shares to Class A shares, there are no
conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.

Pursuant to the Trust's Agreement and Declaration of Trust, the Company may
issue an unlimited number of shares of the Fund. Each share of the Fund
represents an interest in the Fund only, has a par value of $0.01 per share,
represents an equal proportionate interest in the Fund with other shares of the
Fund and is entitled to such dividends and distributions out of the income
earned and gain realized on the assets belonging to the Fund as may be declared
by the Board of Trustees. Each share of the Fund is equal in earnings, assets
and voting privileges, except that each class normally has exclusive voting
rights with respect to its distribution plan and bears the expenses, if any,
related to the distribution of its shares. Shares of the Fund, when issued, are
fully paid and nonassessable.

CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without
a sales charge and Class B shares (the "Class B shares") and Class C shares (the
"Class C shares") of the Multiple Class Funds which offer such classes are sold
at net asset value subject to a contingent deferred sales charge payable upon
certain redemptions. Class B shares of AIM DOLLAR FUND, however, may be acquired
only by an exchange of shares of another AIM Fund. These contingent deferred
sales charges are described under the caption "How to Redeem Shares -- Multiple
Distribution System." Securities dealers and other persons entitled to receive
compensation for selling or servicing shares of a Multiple Class Fund may
receive different compensation for selling or servicing one particular class of
shares over another class in the same Multiple Class Fund. Factors an investor
should consider prior to purchasing Class A, Class B or Class C shares (or, if
applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For
information on purchasing any of the AIM Funds and to receive a prospectus,
please call (800) 347-4246. As described below, the sales charge otherwise
applicable to a purchase of shares of a fund may be reduced if certain
conditions are met. In order to take advantage of a reduced sales charge, the
prospective investor or his dealer must advise AIM Distributors that the
conditions for obtaining a reduced sales charge have been met. Net asset value
is determined in the manner described under the caption "Determination of Net
Asset Value."

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed

<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6

                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9
<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16
<PAGE>
                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25

                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MID CAP GROWTH FUND,

government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

                        PROSPECTUS -- SEPTEMBER 8, 1998
    
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Latin American Growth Fund (the
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end, series, management investment
company. The Fund is a nondiversified portfolio which seeks capital appreciation
by investing primarily in equity and debt securities of a broad range of Latin
American issuers.
    
 
   
The Fund is designed for long term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in lower quality and unrated
foreign government bonds whose credit quality is generally considered the
equivalent of U.S. corporate debt securities commonly known as "junk bonds."
Investments of this type are subject to a greater risk of loss of principal and
interest. An investment in the Fund should be considered speculative and subject
to special risk factors, related primarily to the Fund's investments in Latin
America. Purchasers should carefully assess the risks associated with an
investment in the Fund.
    
 
   
This Prospectus sets forth concisely the information about the Fund that
prospective investors should know before investing. It should be read and
retained for future reference. A Statement of Additional Information dated
September 8, 1998 has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated herein by reference. The Statement of Additional
Information is available without charge upon written request to the Trust at 11
Greenway Plaza, Suite 100, Houston, Texas 77046-1173 or by calling
1-800-347-4246. The SEC maintains a Web site at http://www.sec.gov that contains

other information regarding the Fund. Additional information about the Fund may

The Fund:                      The Fund is a non-diversified series of the Trust.
 
Investment Objective:          The Fund seeks capital appreciation.
 
Principal Investment:          The  Fund normally invests at least  65% of its total assets in  equity and debt securities issued by
                               Latin American companies and governments.
 
Investment Managers:           The Fund is managed by A I M Advisors, Inc. ("AIM") and is sub-advised and sub-administered by
                               INVESCO (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or administrative services to institutional, corporate

                                  (Continued)
- --------------------------------------------------------------------------------
   
<TABLE>
<S>                            <C>                                               <C>
  Class B Shares:              Shares are offered at net asset  value without an initial sales charge  and are subject to a  maximum
                               contingent  deferred sales charge  of 5% on certain  redemptions made within six  years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund  eight
                               years  following the  end of  the calendar month  in which  a purchase was  made. Class  B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must  be at least $500 and additional investments must  be
                               at  least  $50. The  minimum initial  investment  is modified  for investments  through tax-qualified
                               retirement plans  and accounts  initially established  with an  Automatic Investment  Plan. The  dis-
                               tributor  of the  Fund's shares  is A  I M  Distributors, Inc.  ("AIM Distributors"),  P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors      An investor in Class A or Class B shares of the Fund should consider the method of purchasing  shares
                               that  is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors  should consider whether, during the anticipated  life
                               of  their investment  in the Fund,  the accumulated  distribution fees and  any applicable contingent
                               deferred sales charges on  Class B shares prior  to conversion would be  less than the initial  sales
                               charge  and accumulated distribution fees on  Class A shares purchased at  the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist  investors
                               in  making this determination,  the table under the  caption "Table of Fees  and Expenses" sets forth
                               examples of the charges  applicable to each  class of shares.  Class A shares  will normally be  more
                               beneficial  than Class B shares to  the investor who qualifies for  reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, " The AIM  Family
                               of  Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of  Funds in the  manner and subject  to the policies  and charges set  forth herein.  See
                               "Exchange Privilege."
 
Redeeming Shares:              Class  A shareholders of the Fund may  redeem all or a portion of  their shares at net asset value on
                               any business day, generally  without charge. A contingent  deferred sales charge of  1% may apply  to
                               certain  redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

                               Class B shareholders of the Fund may  redeem all or a portion of  their shares at net asset value  on
                               any  business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such  shares were purchased.  Class B  shares redeemed after  six years from  the date  such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
 
Distributions:                 The  Fund currently  declares and pays  dividends from  net investment income,  if any,  on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis.  Dividends
                               and  distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds.  See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There  is no  assurance that the  Fund will  achieve its investment  objective. The  Fund's net asset
                               values will fluctuate, reflecting fluctuations in the market value of the portfolio holdings.
 
                               The Fund will invest primarily in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the  Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies  may be less liquid and  their prices more volatile than  those of securities of comparable
                               U.S. companies.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall  level of investment  and currency risk  associated with its  present or  planned
                               investments. Such transactions involve certain risks and transaction costs.
 
                               There  is no limitation on  the percentage of the  Fund's total assets that  may be invested in below
                               investment grade debt securities. Investments of this type  are subject to a greater risk of loss  of
                               principal and interest.

- --------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charges permitted by the NASD rules regarding investment
    companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect the current expense limits. "Other expenses" include custody,
    transfer agency, legal, audit and other operating expenses. AIM has
    undertaken to limit the Fund's expenses (exclusive of brokerage commissions,
    taxes, interest and extraordinary expenses) to the annual rate of 2.00% and
    2.50% of the average daily net assets of the Fund's Class A and Class B
    shares, respectively. Without reimbursements and waivers, "Other Expenses"
    and "Total Fund Operating Expenses" would have been 0.58% and 2.06%,
    respectively, for Class A shares and 0.58% and 2.56% for Class B Shares of
    the Fund. See "Management" herein and the Statement of Additional
    Information for more information.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the Hypothetical Example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. This information
is supplemented by the financial statements and accompanying notes appearing in
the Statement of Additional Information.
    
 
   
                         AIM LATIN AMERICAN GROWTH FUND

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is capital appreciation. The Fund normally
invests at least 65% of its total assets in the securities of a broad range of
Latin American issuers. The Fund may invest in common stock, preferred stock,
rights, warrants and securities convertible into common stock, and other
substantially similar forms of equity securities with comparable risk
characteristics, as well as bonds, notes, debentures or other forms of
indebtedness that may be developed in the future. Normally, the Fund will invest
a majority of its assets in equity securities. The Fund may also invest up to
35% of its total assets in a combination of equity and debt securities of U.S.
issuers. There can be no assurance that the Fund will meet its investment
objective.
    
 
   
For purposes of this Prospectus, unless otherwise indicated, the Fund defines
Latin America to include the following countries: Argentina, the Bahamas,
Barbados, Belize, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican
Republic, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Haiti,
Honduras, Jamaica, Mexico, the Netherlands Antilles, Nicaragua, Panama,
Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay and Venezuela. Under
current market conditions, the Fund expects to invest primarily in securities
issued by companies and governments in Mexico, Chile, Brazil and Argentina. The
Fund may invest more than 25% of its total assets in any of these four countries
but does not expect to invest more than 60% of its total assets in any one
country.
    
 
   
The Fund defines securities of Latin American issuers to include: (a) securities
of companies organized under the laws of, or having a principal office located
in, a Latin American country; (b) securities of companies that derive 50% or
more of their total revenues from business in Latin America, provided that, in
the Sub-adviser's view, the value of such issuers' securities reflect Latin
American developments to a greater extent than developments elsewhere; (c)
securities issued or guaranteed by the government of a country in Latin America,
its agencies or instrumentalities, or municipalities, or the central bank of
such country; (d) U.S. dollar-denominated securities or securities denominated
in a Latin American currency issued by companies to finance operations in Latin
America; and (e) securities of Latin American issuers, as defined herein, in the
form of depositary shares. For purposes of the foregoing definition, the Fund's
purchases of securities issued by companies outside of Latin America to finance
their Latin American operations will be limited to securities the performance of
which is materially related to such company's Latin American activities.
    
 
In allocating investments among the various Latin American countries, the
Sub-adviser looks principally at the stage of industrialization, potential for
productivity gains through economic deregulation, the impact of financial
liberalization and monetary conditions and the political outlook in each
country. In allocating assets between equity and debt securities, the
Sub-adviser will consider, among other factors: the level and anticipated
direction of interest rates; expected rates of economic growth and corporate
profits growth; changes in Latin American government policy including regulation
governing industry, trade, financial markets, and foreign and domestic
investment; substance and likely development of government finances; and the
condition of the balance of payments and changes in the terms of trade. In
evaluating investments in securities of U.S. issuers, the Sub-adviser will
consider, among other factors, the issuer's Latin American business activities
and the impact that development in Latin America may have on the issuer's
operations and financial condition.
 
   
Certain sectors of the economies of certain Latin American countries are closed
to equity investments by foreigners. Further, due to the absence of securities
markets and publicly owned corporations and due to restrictions on direct
investment by foreign entities in certain Latin American countries, the Fund may
be able to invest in such countries solely or primarily through governmentally
approved investment vehicles or companies. In addition, the portion of the
Fund's assets invested directly in Chile may be less than the portion invested
in other Latin American countries because, at present, capital directly invested
in Chile normally cannot be repatriated for at least one

                         AIM LATIN AMERICAN GROWTH FUND
year. As a result, the Fund currently intends to limit most of its Chilean
investments to indirect investments through American Depositary Receipts
("ADRs") and established Chilean investment companies, the shares of which are
not subject to repatriation restrictions.
 
   
INVESTMENTS IN DEBT SECURITIES. Under normal circumstances, the Fund may invest
up to 50% of its total assets in debt securities. There is no limitation on the
percentage of its assets that may be invested in debt securities that are rated
below investment grade. Investment in below investment grade debt securities
involves a high degree of risk and can be speculative. These debt securities are
the equivalent of high yield, high risk bonds, commonly known as "junk bonds."
Most debt securities in which the Fund will invest are not rated; if rated, it
is expected that such ratings would be below investment grade. However, the Fund
will not invest in debt securities that are in default in payment as to
principal or interest. See "Risk Factors -- Risks Associated with Debt
Securities."
    
 
   
The Fund may invest in "Brady Bonds," which are debt restructurings that provide
for the exchange of cash and loans for newly issued bonds. Brady Bonds have been
issued by the countries of Albania, Argentina, Brazil, Bulgaria, Costa Rica,
Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria, Panama, Peru,
Philippines, Poland, Uruguay, Venezuela and Vietnam, and are expected to be
issued by other emerging market countries. As of the date of this Prospectus,
the Fund is not aware of the occurrence of any payment defaults on Brady Bonds.
Investors should recognize, however, that Brady Bonds do not have a long payment
history. In addition, Brady Bonds are often rated below investment grade.
    
 
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
 
   
Capital appreciation in debt securities may arise as a result of a favorable
change in relative foreign exchange rates, in relative interest rate levels and/
or in the creditworthiness of issuers. The receipt of income from debt
securities owned by the Fund is incidental to its objective of capital
appreciation.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Fund may invest up to 100% of its assets in
cash (U.S. dollars, foreign currencies, multinational units such as Euros)
and/or high quality debt securities or money market instruments to generate
income to defray its expenses, for temporary defensive purposes and pending
investment in accordance with its investment objective and policies. In
addition, the Fund may be primarily invested in U.S. securities for temporary
defensive purposes or pending investment of the proceeds of sales of new Fund
shares. The Fund may assume a temporary defensive position when, due to
political, market or other factors broadly affecting Latin American markets, the
Sub-adviser determines that opportunities for capital appreciation in those
markets would be significantly limited over an extended period or that investing
in those markets presents undue risk of loss. For a full description of money
market instruments, see "Temporary Defensive Strategies" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
   
ADDITIONAL INVESTMENT POLICIES
    
 
   
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940 (the "1940
Act"), the Fund generally may invest up to 10% of its total assets in the
aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
    
 
   
Investment in other investment companies may involve the payment of substantial
premiums above the value of such investment companies' portfolio securities and
is subject to limitations under the 1940 Act and market availability. The Fund
does not intend to invest in such investment companies unless, in the judgment
of the Sub-adviser, the
    
 
                               Prospectus Page 8
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
potential benefits of such investment justify the payment of any applicable
premium or sales charge. As a shareholder in an investment company, the Fund
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time the Fund would continue
to pay its own management fees and other expenses. AIM and the Sub-adviser will
waive their advisory fees to the extent that the Fund invests in an Affiliated
Fund.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows a Fund to retain
ownership of the securities loaned and, at the same time, enhances the Fund's
total return. At all times a loan is outstanding, the Fund's borrower must
maintain with the Fund's custodian collateral consisting of cash, U.S.
government securities or certain irrevocable letters of credit equal to the
value of the borrowed securities plus any accrued interest or such other
collateral as permitted by the Fund's investment program and regulatory
agencies, and as approved by the Board. The Fund limits its loans of portfolio
securities to an aggregate of 30% of the value of its total assets, measured at
the time any such loan is made. The risks in lending portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional collateral or in recovery of the loaned securities and possible loss
of rights in the collateral should the borrower fail financially.
    
 
   
PRIVATIZATIONS. The governments in some Latin American countries have been
engaged in programs of selling part or all of their stakes in government owned
or controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain Latin American countries, the ability of foreign
entities such as the Fund to participate in privatizations may be limited by
local law, or the terms on which the Fund may be permitted to participate may be
less advantageous than those afforded local investors. There can be no assurance
that Latin American governments and governments in emerging markets will
continue to sell companies currently owned or controlled by them or that
privatization programs will be successful.
    
 
   
BORROWING. It is a fundamental policy of the Fund that it may borrow an amount
up to 33 1/3% of its total assets in order to meet redemption requests.
Borrowing may cause greater fluctuation in the value of the Fund's shares than
would be the case if the Fund did not borrow, but also may enable the Fund to
retain favorable securities positions rather than liquidating such positions to
meet redemptions. It is a nonfundamental policy of the Fund, that the Fund will
not purchase securities during times when outstanding borrowings represent 5% or
more of each Fund's total assets.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian bank and will mark to market daily such assets.
There is a risk that the securities may not be delivered and that the Fund may
incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment risk normally associated with the
portfolio. These instruments are often referred to as "derivatives," which may
be defined as financial instruments whose performance is derived, at least in
part, from the performance of another asset (such as a security, currency or an
index of securities). The Fund may enter into such instruments up to the full
value of its portfolio assets. See "Risk Factors -- Options, Futures and Foreign
Currency Transactions" herein and "Options, Futures and Currency
    
 
                               Prospectus Page 9
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
Strategies" in the Statement of Additional Information.
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge against movements in exchange rates.
    
 
   
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most Latin American markets, to
securities denominated in such currencies or to securities of issuers domiciled
or principally engaged in business in such emerging markets. To the extent that
such a market does not exist, the Sub-adviser may not be able to effectively
hedge its investment in such markets.
    
 
   
The Fund may purchase and sell put and call options on securities to hedge
against the risk of fluctuations in the prices of securities held by the Fund or
that the Sub-adviser intends to include in the Fund's portfolio. The Fund also
may purchase and sell put and call options on indices to hedge against overall
fluctuations in the securities markets generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
adversely affect the Fund's portfolio. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolios against changes in the general level of interest
rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations as
fundamental policies which also may not be changed without shareholder approval.
A complete description of these limitations is included in the Statement of
Additional Information. Unless specifically noted, the Fund's investment
policies described in this Prospectus and in the Statement of Additional
Information may be changed by the Trust's Board of Trustees without shareholder
approval. If a percentage restriction on investment or utilization of assets in
an investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. Investing in the Fund entails a substantial degree of risk and an
investment in the Fund should be considered speculative. Investors are strongly
advised to consider carefully the special risks involved in Latin America, which
are in addition to the usual risks of investing in developed markets around the
world.
    
 
   
The Fund's net asset value will fluctuate, reflecting fluctuations in the market
value of its portfolio positions and its net currency exposure. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Fund will fluctuate
in response to general market and economic developments, as well as developments
affecting the particular issuers of such securities.
    
 
   
The Fund is classified under the 1940 Act as a "non-diversified" fund. As a
result, the Fund will be able to invest in a fewer number of issuers than if it
were classified under the 1940 Act as a "diversified" fund. To the extent that
the Fund invests in a smaller number of issuers, the value of its shares may
fluctuate more widely and it may be subject to greater investment and credit
risk with respect to its portfolio.
    
 
   
Investing in securities of Latin American issuers involves risks relating to
potential political and economic instability of certain Latin American countries
and the risks of expropriation, nationalization, confiscation of assets and
property or the imposition of restrictions on foreign investment and on
repatriation of capital invested. In the event of such expropriation,
nationalization or other confiscation, the Fund could lose its entire investment
in any such country.
    
 
The securities markets of Latin American countries are substantially smaller,
less developed, less liquid and more volatile than the major securities markets
in the United States. Disclosure and regulatory standards are in many respects
less stringent than U.S. standards. Furthermore, there is a lower level of
monitoring and regulation of the markets and the activities of investors in such
markets, and enforcement of existing regulations has been extremely limited.
 
The limited size of many Latin American securities markets and limited trading
volume in issuers compared to volume of trading in U.S. securities could cause
prices to be erratic for reasons apart from factors that affect the quality of
the securities. For example, limited market size may cause prices to be unduly
influenced by traders who control large positions. Adverse publicity and
investors' perceptions, whether or not based on fundamental analysis, may
decrease the value and liquidity of portfolio securities, especially in these
markets.
 
   
Further, there is a risk that an emergency situation may arise in one or more
Latin American markets as a result of which prices for portfolio securities in
such markets may not be readily available. Section 22(e) of the 1940 Act permits
a registered investment company, such as the Fund, to suspend redemption of its
shares for any period during which an emergency exists, as determined by the
SEC. Accordingly, when the Fund believes that circumstances dictate, it will
promptly apply to the SEC for a determination that such an emergency exists
within the meaning of Section 22(e) of the 1940 Act. During the period
commencing from the Fund's identification of such conditions until the date of
any SEC action, the Fund's portfolio securities in the affected markets will be
valued at fair value determined in good faith by or under the direction of the
Trust's Board of Trustees.
    
 
The economies of individual Latin American countries may differ favorably or
unfavorably from the U.S. economy in such respects as the rate of growth of
gross domestic product, the rate of inflation, capital reinvestment, resource
self-sufficiency and balance of payments position. Most Latin American countries
have experienced substantial, and in some periods extremely high, rates of
inflation for many years. Inflation and rapid fluctuations in inflation rates
have had and may continue to have very negative effects on the economies and
securities markets of certain Latin American countries. Furthermore, certain
Latin American countries may impose withholding taxes
 
                               Prospectus Page 11
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
on dividends payable to the Fund at a higher rate than those imposed by other
foreign countries. This may reduce the Fund's investment income available for
distribution to shareholders.
    
 
Companies in Latin America are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from those
applicable to U.S. companies. There is substantially less publicly available
information about Latin American companies and the governments of Latin American
countries than there is about U.S. companies and the U.S. Government.
 
Certain Latin American countries are among the largest debtors to commercial
banks and foreign governments. At times certain Latin American countries have
declared moratoria on the payment of principal and/or interest on external debt.
The Fund may invest in debt securities, including Brady Bonds, issued as part of
debt restructurings and such debt is to be considered speculative. There is a
history of defaults with respect to commercial bank loans by public and private
entities issuing Brady Bonds.
 
   
RISKS ASSOCIATED WITH DEBT SECURITIES. The value of the debt securities held by
the Fund generally will vary inversely with market interest rates. If interest
rates in a market fall, the Fund's debt securities issued by governments or
companies in that market ordinarily will increase in value. If market interest
rates increase, however, the debt securities owned by the Fund in that market
will likely decrease in value.
    
 
   
The Fund may invest up to 50% of its total assets in debt securities of any
rating. Such investments involve a high degree of risk.
    
 
Debt rated Baa by Moody's Investors Service, Inc. ("Moody's") is considered by
Moody's to have speculative characteristics. Debt rated BB, B, CCC, CC or C by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), and
debt rated Ba, B, Caa, Ca or C by Moody's is regarded, on balance, as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. While such
lower quality debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
conditions. Debt rated C by Moody's or S&P is the lowest rated debt that is not
in default as to principal or interest and such issues so rated can be regarded
as having extremely poor prospects of ever attaining any real investment
standing. Lower quality debt securities are also generally considered to be
subject to greater risk than securities with higher ratings with regard to a
deterioration of general economic conditions. These foreign debt securities are
the equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. Similarly, certain Latin American governments that issue lower
quality debt securities are among the largest debtors to commercial banks,
foreign governments and supranational organizations such as the World Bank, and
may not be able or willing to make principal and/ or interest repayments as they
come due. The risk of loss due to default by the issuer is significantly greater
for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities frequently have call or buy-back features which
would permit an issuer to call or repurchase the security from the Fund. In
addition, the Fund may have difficulty disposing of lower quality securities
because they may have a
    
 
                               Prospectus Page 12
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
thin trading market. There may be no established retail secondary market for
many of these securities, and the Fund anticipates that such securities could be
sold only to a limited number of dealers or institutional investors. The lack of
a liquid secondary market also may have an adverse impact on market prices of
such instruments and may make it more difficult for the Fund to obtain accurate
market quotations for purposes of valuing the Fund's portfolio. The Fund may
also acquire lower quality debt securities during an initial underwriting or
which are sold without registration under applicable securities laws. Such
securities involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession.
    
 
   
The Fund may also incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in Latin American markets can
differ from debt obligations issued by private entities in that remedies from
defaults generally must be pursued in the courts of the defaulting government,
and legal recourse is therefore somewhat diminished. Political conditions, in
terms of a government's willingness to meet the terms of its debt obligations,
also are of considerable significance. There can be no assurance that the
holders of commercial bank debt may not contest payments to the holders of debt
securities issued by governments in Latin American markets in the event of
default by the governments under commercial bank loan agreements.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 10% of its net assets in
securities for which no readily available market exists, so-called "Illiquid
Securities." The Fund may invest in joint ventures, cooperatives, partnerships
and state enterprises and other similar vehicles which are illiquid
(collectively, "Special Situations"). The Sub-adviser believes that carefully
selected investments in Special Situations could enable the Fund to achieve
capital appreciation substantially exceeding the appreciation the Fund would
realize if it did not make such investments. However, in order to limit
investment risk, the Fund will invest no more than 5% of its total assets in
Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
CURRENCY RISK. Because the Fund may invest substantially in securities
denominated in currencies other than the U.S. dollar, and since the Fund may
hold foreign currencies, the Fund will be affected favorably or unfavorably by
exchange control regulations or changes in the exchange rates between such
currencies and the U.S. dollar. Changes in currency exchange rates will
influence the value of the Fund's shares, and also may affect the value of
dividends and interest earned by the Fund and gains and losses realized by the
Fund. Currencies generally are evaluated on the basis of fundamental economic
criteria (e.g., relative inflation and interest rate levels and trends, growth
rate forecasts, balance of payments status and economic policies) as well as
technical and political data. Exchange rates are determined by the forces of
supply and demand in the foreign exchange markets. These forces are affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. If the
currency in which a security is denominated appreciates against the U.S. dollar,
the dollar value of the security will increase. Conversely, a decline in the
exchange rate of the currency would adversely affect the value of the security
expressed in dollars.
    
 
   
Many of the currencies of Latin American countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries. Any devaluations in the currencies
in which the Fund's portfolio securities are denominated may have a detrimental
impact on the Fund.
    
 
Some countries also may have fixed currencies whose values against the U.S.
dollar are not independently determined. In addition, there is a risk that
certain countries may restrict the free conversion of their currencies into
other currencies. Further, certain currencies may not be internationally traded.
 
   
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency

                         AIM LATIN AMERICAN GROWTH FUND
   
transactions involve certain risks, which include: (1) dependence on the
Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets and movements in
interest rates and currency markets; (2) imperfect correlation, or even no
correlation, between movements in the price of forward contracts, options,
futures contracts or options thereon and movements in the price of the currency
or security hedged or used for cover; (3) the fact that skills and techniques
needed to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Fund invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of a Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for the Fund to sell a security at a disadvantageous time, due to
the need for the Fund to maintain "cover" or to set aside securities in
connection with hedging transactions.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day to day operations of the Fund are delegated to the officers
of the Trust, subject always to the objective and policies of the Fund and to
the general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's Board of Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the Fund's portfolio and
placing orders to buy, sell or hold particular securities; furnishing corporate
officers and clerical staff; providing office space, services and equipment; and
supervising all matters relating to the Fund's operation. For these services,
the Fund pays AIM investment management and administration fees, computed daily
and paid monthly, based on its average daily net assets, at the annualized rate
of .975% on the first $500 million, .95% on the next $500 million, .925% on the
next $500 million, and .90% on amounts thereafter. Out of the aggregate fees
payable by the Fund, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit the Fund's expenses (exclusive of brokerage commissions,
taxes, interest and extraordinary expenses) to the annual rate of 2.00% and
2.50% of the average daily net assets of the Fund's Class A and Class B shares,
respectively.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-Adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The

Sub-adviser, 50 California Street, 27th Floor, San Francisco, California 94111,
and 1166 Avenue of the Americas, New York, New York 10036, serves as the
sub-adviser to the Fund pursuant to an investment sub-advisory and
sub-administration agreement dated as of May 29, 1998. Prior to May 29, 1998,
the Sub-adviser was known as Chancellor LGT Asset Management, Inc. On May 29,
1998, Liechtenstein Global Trust AG ("LGT"), the former indirect parent
organization of the Sub-adviser, consummated a purchase agreement with AMVESCAP
PLC pursuant to which AMVESCAP PLC acquired LGT's Asset Management Division,
which included the Sub-adviser and certain other affiliates. As a result of this
transaction, the Sub-adviser is now an indirect wholly-owned subsidiary of
AMVESCAP PLC. Prior to the sale, the Sub-adviser and its worldwide asset
management affiliates provided investment management and/or administrative
services to institutional, corporate and individual clients around the world
since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
   
The investment professionals primarily responsible for the portfolio management
of the Fund are as follows:

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser. High portfolio turnover (over
100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund will bear directly and could result in the
realization of net capital gains which would be taxable when distributed to
shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998, on behalf of Class A shares of the Fund and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements.") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.

<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attibutable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares master distribution plan (as defined in the plan) would terminate all
payments to AIM Distributors. Termination of the Class B shares distribution
plan or Distribution Agreement does not affect the obligation of Class B
shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.50% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
 
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B Plan, the
Fund pays distribution expenses at an annual rate of 1.00% of the average daily
net assets attributable to the Fund's Class B shares. Of such amount the Fund
pays a service fee of 0.25% of the average daily net assets attributable to the
Fund's Class B shares to selected dealers and financial institutions who furnish
continuing personal shareholder services to their customers who purchase and own
Class B shares of the Fund.

<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
Any amounts not paid as a service fee would constitute an asset-based sales
charge. Amounts paid in accordance with the Class B Plan with respect to the
Fund may be used to finance any activity primarily intended to result in the
sale of Class B shares of the Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the Class A Plan and the Class
B Plan (collectively, the "Plans") include, but are not limited to: printing of
prospectuses and statements of additional information and reports for other than
existing shareholders, overhead, preparation and distribution of advertising
material and sales literature, expense of organizing and conducting sales
seminars, supplemental payments to dealers and other institutions such as
asset-based sales charges or as payments of service fees under shareholder
service arrangements, and the cost of administering the Plans. These amounts
payable by the Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of the Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Trust will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland Corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other
    
 
                               Prospectus Page 17

                         AIM LATIN AMERICAN GROWTH FUND
   
series do not have cumulative voting rights, which means that the holders of a
majority of the shares voting for the election of Trustees can elect all the
Trustees. A Trustee may be removed at any meeting of the shareholders of the
Trust by a vote of the shareholders owning at least two-thirds of the
outstanding shares. Any Trustee may call a special meeting of shareholders for
any purpose. Furthermore, Trustees shall promptly call a meeting of shareholders
solely for the purpose of removing one or more Trustees when requested in
writing to do so by shareholders holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without
a sales charge and Class B shares (the "Class B shares") and Class C shares (the
"Class C shares") of the Multiple Class Funds which offer such classes are sold
at net asset value subject to a contingent deferred sales charge payable upon

receive different compensation for selling or servicing one particular class of
shares over another class in the same Multiple Class Fund. Factors an investor
should consider prior to purchasing Class A, Class B or Class C shares (or, if
applicable, AIM Cash Reserve Shares) of a Multiple Class Fund are described
below under "Special Information Relating to Multiple Class Funds." For
information on purchasing any of the AIM Funds and to receive a prospectus,
please call (800) 347-4246. As described below, the sales charge otherwise
applicable to a purchase of shares of a fund may be reduced if certain
conditions are met. In order to take advantage of a reduced sales charge, the
prospective investor or his dealer must advise AIM Distributors that the
conditions for obtaining a reduced sales charge have been met. Net asset value

    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus

                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed

                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6

                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for
employees of AIM Management or its affiliates; (d) any current or retired
officer, director, trustee or employee, or any member of
 
                                      A-9
<PAGE>
                              AIM INVESTOR'S GUIDE
   
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone
 
                                      A-10
<PAGE>
                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,

includes a maximum sales charge of 5.50% or 4.75% of the public offering price
of such shares; Class A shares (or shares which normally involve the payment of
initial sales charges) of certain of the AIM Funds, listed below and referred to
herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16
<PAGE>
                              AIM INVESTOR'S GUIDE
   
charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain
    
 
                                      A-19
<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an
 
                                      A-20
<PAGE>
                              AIM INVESTOR'S GUIDE
address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

                              AIM INVESTOR'S GUIDE
not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25

                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MID CAP GROWTH FUND,

government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Strategic Income Fund (the
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end series, management investment
company. The Fund is a non-diversified portfolio which primarily seeks high
current income and secondarily seeks capital appreciation. The Fund allocates
its assets among debt securities of issuers in: (1) the United States; (2)
developed foreign countries; and (3) emerging markets.
    
 
   
The Fund is designed for long-term investors and not as a trading vehicle, does
not represent a complete investment program and is not suitable for all
investors. An investment in the Fund involves risk factors that should be
reviewed carefully by potential investors. The Fund is authorized to borrow
money for investment purposes, which would increase the volatility of its
performance and involves additional risks. See "Investment Objectives and
Policies" and "Risk Factors."
    
 
   
THE STRATEGIC INCOME FUND INVESTS UP TO 50% OF ITS TOTAL ASSETS IN LOWER QUALITY
AND UNRATED FOREIGN GOVERNMENT BONDS WHOSE CREDIT QUALITY IS GENERALLY
CONSIDERED THE EQUIVALENT OF U.S. CORPORATE DEBT SECURITIES COMMONLY KNOWN AS
"JUNK BONDS." INVESTMENTS OF THIS TYPE ARE SUBJECT TO A GREATER RISK OF LOSS OF
PRINCIPAL AND INTEREST. PURCHASERS SHOULD CAREFULLY ASSESS THE RISKS ASSOCIATED
WITH AN INVESTMENT IN THE FUND. SEE "INVESTMENT OBJECTIVES AND POLICIES" AND
"RISK FACTORS."
    
 
   
This Prospectus sets forth concisely information about the Fund that prospective
investors should know before investing. It should be read and retained for
future reference. A Statement of Additional Information, dated September 8,
1998, has been filed with the Securities and Exchange Commission ("SEC") and is
incorporated herein by reference. The Statement of Additional Information is
available without charge upon written request to the Trust at 11 Greenway Plaza,

The Fund:                      The Fund is a non-diversified series of the Trust.
 
Investment Objectives:         The Fund primarily seeks high current income and secondarily seeks capital appreciation.
 
Principal Investments:         The Fund allocates its assets among debt securities of issuers in: (1) the United States; (2)
                               developed foreign countries; and (3) emerging markets, and selects particular securities in each
                               sector based on their relative investment merit.
 
Investment Managers:           The Fund is managed by A I M Advisors, Inc. ("AIM") and is sub-advised and sub-administered by
                               INVESCO (NY), Inc. (the "sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or administrative services to institutional, corporate
                               and individual clients around the world. AIM and the Sub-adviser are both indirect wholly owned
                               subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its subsidiaries are an independent investment man-
                               agement group that has a significant presence in the institutional and retail segment of the
                               investment management industry in North America and Europe, and a growing presence in Asia. AIM was
                               organized in 1976 and, together with its subsidiaries, currently advises approximately 90 investment
                               company portfolios.
 
Purchasing Shares:             Investors may select Class A or Class B shares of the Fund which are offered by this Prospectus at an
                               offering price that reflects differing sales charges and expense levels. See "Terms and Conditions of
                               Purchase of the AIM Funds -- Sales Charges and Dealer Concessions." Pursuant to a separate
                               prospectus, the Fund also offers Advisor Class shares, which represent interests in the Fund. The
                               Advisor Class has different distribution arrangements.

                                  (Continued)

<TABLE>
<S>                            <C>                                               <C>
  Class B Shares:              Shares are offered at net asset value without an initial sales charge, and are subject to a maximum
                               contingent deferred sales charge of 5% on certain redemptions made within six years from the date
                               such shares were purchased. Class B shares automatically convert to Class A shares of the Fund eight
                               years following the end of the calendar month in which a purchase was made. Class B shares are
                               subject to higher expenses than Class A shares.
 
                               Initial investments in any class of shares must be at least $500 and additional investments must be
                               at least $50. The minimum initial investment is modified for investments through tax-qualified
                               retirement plans and accounts initially established with an Automatic Investment Plan. The dis-
                               tributor of the Fund's shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
                               Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
Suitability for Investors      An investor in Class A or Class B shares of the Fund should consider the method of purchasing shares
                               that is most beneficial given the amount of the purchase, the length of time the shares are expected
                               to be held, and other circumstances. Investors should consider whether, during the anticipated life
                               of their investment in the Fund, the accumulated distribution fees and any applicable contingent
                               deferred sales charges on Class B shares prior to conversion would be less than the initial sales
                               charge and accumulated distribution fees on Class A shares purchased at the same time, and to what
                               extent such differential would be offset by the higher return on Class A shares. To assist investors
                               in making this determination, the table under the caption "Table of Fees and Expenses" sets forth
                               examples of the charges applicable to each class of shares. Class A shares will normally be more
                               beneficial than Class B shares to the investor who qualifies for reduced initial sales charges, as
                               described below. Therefore, AIM Distributors will reject any order for purchase of more than $250,000
                               for Class B shares.
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Class A and Class B shares of the Fund may be exchanged for shares of other funds in The
                               AIM Family of Funds in the manner and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Class A shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, generally without charge. A contingent deferred sales charge of 1% may apply to
                               certain redemptions where a purchase of more than $1 million is made at net asset value. See "How to
                               Redeem Shares -- Contingent Deferred Sales Charge Program for Large Purchases."

<S>                            <C>                                               <C>
                               Class B shareholders of the Fund may redeem all or a portion of their shares at net asset value on
                               any business day, less a contingent deferred sales charge for redemptions made within six years from
                               the date such shares were purchased. Class B shares redeemed after six years from the date such
                               shares were purchased will not be subject to any contingent deferred sales charge. See "How to Redeem
                               Shares -- Multiple Distribution System."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a monthly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters" and "Special Plans."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objectives. The Fund's net asset
                               value will fluctuate, reflecting fluctuations in the market value of its portfolio holdings. The
                               value of debt securities held by the Fund generally fluctuates inversely with interest rate
                               movements.
 
                               The Fund will invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies. The Fund may invest in debt securities of issuers in emerging markets. Such
                               investments entail greater risks than investing in securities of issuers in developed markets.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
 
                               The Fund may invest up to 50% of its total assets in debt securities rated below investment grade or,
                               if not rated, determined by the Sub-adviser to be of comparable quality. Investments of this type are
                               subject to greater risk of loss of principal and interest.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies.
    
 
   
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
    Sales Charges."
    
 
   
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agency, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information.
    
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.
 
   
(6) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
    The table and the assumption in the Hypothetical Example of a 5% annual
    return are required by regulation of the SEC applicable to all mutual funds;
    the 5% annual return is not a prediction of and does not represent the Fund.
    
 
   
(7) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which a purchase was
    made.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Class A and Class B share of the Fund. For the period
March 29, 1988 (commencement of operations) to October 22, 1992, the Strategic
Income Fund was named G.T. Global Bond Fund and operated under different
investment objectives, policies and limitations. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
   
                           AIM STRATEGIC INCOME FUND
                   (FORMERLY GT GLOBAL STRATEGIC INCOME FUND)
    
 
   
                                 [TO BE ADDED]
    
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. Standardized total return for Class
A shares reflects the deduction of the Fund's maximum front-end sales charge at
the time of purchase. Standardized total return for Class B shares reflects the
deduction of the maximum applicable contingent deferred sales charge on a
redemption of shares held for the period.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of the maximum offering price per share
for Class A shares and net asset value per share for Class B shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed.

These factors should be carefully considered by the investor before making an
investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and /or assume certain expenses of any fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.
    
 
   
                             INVESTMENT OBJECTIVES
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund primarily seeks high current income and secondarily seeks capital
appreciation. There can be no assurance that the fund will achieve its
investment objective.
    
 
The Fund invests in debt securities of issuers in: (1) the United States; (2)
developed foreign countries; and (3) emerging markets. The Fund selects debt
securities from those issued by governments, their agencies and
instrumentalities; central banks; and commercial banks and other corporate
entities. Debt securities in which the Fund may invest include bonds, notes,
debentures, and other similar instruments including mortgage-backed and
asset-backed securities of foreign issuers as well as domestic issuers. The Fund
normally invests at least 50% of its net assets in U.S. and foreign debt and
other fixed income securities that, at the time of purchase, are rated at least
investment grade by Moody's or S&P or, if not rated, determined by the
Sub-adviser to be of comparable quality. No more than 50% of the Fund's total
assets may be invested in securities rated below investment grade. Such
securities involve a high degree of risk and are predominantly speculative. They
are the equivalent of high yield, high risk bonds, commonly known as "junk
bonds." The Fund may also invest in securities that are in default as to payment
of principal and/or interest.
 
   
The Fund's investments in emerging market securities may consist substantially
of Brady Bonds (see "General Policies -- Brady Bonds," below) and other
sovereign debt securities issued by emerging market governments that are traded
in the markets of developed countries or groups of developed countries. The
Sub-adviser may invest in debt securities of emerging market issuers that it
determines to be suitable investments for the Fund without regard to ratings.
Currently, the substantial majority of emerging market debt securities are
considered to have a credit quality below investment grade. The Fund also may
invest in below-investment grade debt securities of corporate issuers in the
United States and in developed foreign countries, subject to the overall 50%
limitation.
    
 
                                GENERAL POLICIES
 
   
ASSET ALLOCATION. The Fund invests in debt obligations allocated among diverse
markets and denominated in various currencies, including U.S. dollars, or in
multinational currency units such as Euros. The Fund is designed for investors
who wish to accept the risks entailed in such investments, which are different
from those associated with a portfolio consisting entirely of securities of U.S.
issuers denominated in U.S. dollars. The Fund may purchase securities that are
issued by the government or a company or financial institution of one country
but denominated in the currency of another country (or a multinational currency
unit).
    
 
   
The Sub-adviser allocates the assets of the Fund in securities of issuers in
countries and in currency denominations where the combination of fixed income
market returns, the price appreciation potential of fixed income securities and
currency exchange rate movements will present opportunities primarily for high
current income and secondarily for capital appreciation. In so doing, the Sub-
adviser intends to take full advantage of the different yield, risk and return
characteristics that investment in the fixed income markets of different
countries can provide for U.S. investors. Fundamental economic strength, credit
quality and currency and interest rate trends are the principal determinants of
the emphasis given to various country, geographic and industry sectors within
the Fund. Securities held by the Fund may be invested in without limitation as
to maturity.
    
 
                               Prospectus Page 7
<PAGE>
                           AIM STRATEGIC INCOME FUND
 
The Sub-adviser selects securities of particular issuers on the basis of its
views as to the best values then currently available in the marketplace. Such
values are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political developments and variations in the supply of funds available
for investment in the world bond market relative to the demands placed upon it.
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation, interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Sub-adviser may seek to protect the Fund
against such negative currency movements through the use of sophisticated
investment techniques. See "Options, Futures and Forward Currency Transactions"
and "Swaps, Caps, Floors and Collars."
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the value of all outstanding government debt obligations throughout the world
is represented by obligations denominated in currencies other than the U.S.
dollar. Moreover, from time to time, the debt securities of issuers located
outside the United States have substantially outperformed the debt obligations
of U.S. issuers. Accordingly, the Sub-adviser believes that the Fund's policy of
investing in debt securities throughout the world may enable the achievement of
results superior to those produced by mutual funds with similar objectives to
those of the Fund that invest solely in debt securities of U.S. issuers.
    
 
   
The Fund is designed for investors who wish to accept the risks entailed in such
investments, which are different from those associated with a portfolio
consisting entirely of securities of U.S. issuers denominated in U.S. dollars.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Sub-adviser may employ a temporary defensive
investment strategy if it determines such a strategy to be warranted due to
market, economic or political conditions. Pursuant to such a defensive strategy,
the Fund temporarily may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and/or invest up to 100% of its assets in high
quality debt securities or money market instruments of U.S. or foreign issuers.
In addition, for temporary defensive purposes, most or all of the Fund's
investments may be made in the United States and denominated in U.S. dollars. To
the extent the Fund employs a temporary defensive strategy, it will not be
invested so as to achieve directly its investment objectives. In addition,
pending investment of proceeds from new sales of Fund shares or to meet ordinary
daily cash needs, the Fund may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and may invest in high quality foreign or domestic
money market instruments. For a full description of money market instruments,
see "Selection of Debt Investments" in the "Investment Objectives and Policies"
section of the Statement of Additional Information.
    
 
   
EMERGING MARKET SECURITIES. The Fund considers "emerging markets" to consist of
all countries determined by the Sub-adviser to have developing or emerging
economies and markets. These countries generally include every country in the
world except the United States, Canada, Japan, Australia, New Zealand and most
countries located in Western Europe. The Fund will consider investment in the
following emerging markets:

</TABLE>
 
   
The Fund will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements, overly burdensome repatriation
requirements and similar restrictions, the lack of organized and liquid
securities markets, unacceptable political risks or for other reasons.
    
 
As used in this Prospectus and the Statement of Additional Information, an
issuer in an emerging
 
                               Prospectus Page 8
<PAGE>
                           AIM STRATEGIC INCOME FUND
market is an entity: (i) for which the principal securities trading market is an
emerging market, as defined above; (ii) that (alone or on a consolidated basis)
derives 50% or more of its total revenue from either goods produced, sales made
or services performed in emerging markets; or (iii) organized under the laws of,
or with a principal office in, an emerging market.
 
   
BRADY BONDS. The Fund may invest in "Brady Bonds," which are debt restructurings
that provide for the exchange of cash and loans for newly issued bonds. Brady
Bonds have been issued by the countries of Albania, Argentina, Brazil, Bulgaria,
Costa Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria,
Panama, Peru, Philippines, Poland, Uruguay, Venezuela and Vietnam and are
expected to be issued by other emerging market countries. As of the date of this
Prospectus, the Fund is not aware of the occurrence of any payment defaults on
Brady Bonds. Investors should recognize, however, that Brady Bonds do not have a
long payment history. In addition, Brady Bonds are often rated below investment
grade.
    
 
   
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The Fund may invest in
mortgage-backed and asset-backed securities of U.S. and foreign issuers,
including privately issued mortgage-backed and asset-backed securities.
Mortgage-backed securities represent direct or indirect interests in pools of
underlying mortgage loans that are secured by real property. Investors typically
receive payments out of the interest on and principal of the underlying
mortgages. Asset-backed securities are similar to mortgage-backed securities,
except that the underlying assets are other financial assets or financial
receivables, such as motor vehicle installment sales contracts, home equity
loans, leases of various types of real and personal property, and receivables
from credit cards. Any mortgage-backed and asset-backed securities purchased by
the Fund will be subject to the same rating requirements that apply to its other
investments.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may invest in fixed and floating
rate loans ("Loans") arranged through private negotiations between a foreign
entity and one or more financial institutions ("Lenders"). The majority of the
Fund's investments in Loans in emerging markets is expected to be in the form of
participations in Loans ("Participations") and assignments of portions of Loans
from third parties ("Assignments"). Participations typically will result in the
Fund having a contractual relationship only with the Lender, not with the
borrower government. The Fund will have the right to receive payments of
principal, interest and any fees to which it is entitled only from the Lender
selling the Participation and only upon receipt by the Lender of the payments
from the borrower. In connection with purchasing Participations, the Fund
generally will have no right to enforce compliance by the borrower with the
terms of the loan agreement relating to the loan ("Loan Agreement"), nor any
rights of set-off against the borrower, and the Fund may not directly benefit
from any collateral supporting the Loan in which it has purchased the
Participation. As a result, the Fund will assume the credit risk of both the
borrower and the Lender that is selling the Participation.
    
 
   
In the event of the insolvency of the Lender selling a Participation, the Fund
may be treated as a general creditor of the Lender and may not benefit from any
set-off between the Lender and the borrower. The Fund will acquire
Participations only if the Lender interpositioned between the Fund and the
borrower is determined by the Sub-adviser to be creditworthy. When the Fund
purchases Assignments from Lenders, the Fund will acquire direct rights against
the borrower on the Loan. However, since Assignments are arranged through
private negotiations between potential assignees and assignors, the rights and
obligations acquired by the Fund as the purchaser of an Assignment may differ
from, and be more limited than, those held by the assigning Lender.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and
    
 
                               Prospectus Page 9
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
payment for the securities take place at a later date. When-issued securities
and forward commitments may be sold prior to the settlement date, but the Fund
will purchase or sell when-issued securities and forward commitments only with
the intention of actually receiving or delivering the securities, as the case
may be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery of the
securities. If the Fund disposes of the right to acquire a when-issued security
prior to its acquisition or disposes of its right to deliver or receive against
a forward commitment, it may incur a gain or loss. At the time the Fund enters
into a transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss.
    
 
   
The Fund may also sell securities on a "when, as and if issued" basis for
hedging purposes. Under such a transaction, the Fund is required to deliver at a
future date a security it does not presently hold, but which it has a right to
receive if the security is issued. Issuance of the security may not occur, in
which case the Fund would have no obligation to the other party, and would not
receive payment for the sale. Selling securities on a "when, as and if issued"
basis may reduce risk of loss to the extent that such a sale wholly or partially
offsets unfavorable price movements on the investments being hedged. However,
such sales also limit the amount the Fund can receive if the "when, as and if
issued" security is in fact issued.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund is
authorized to borrow money from banks in an amount up to 33 1/3% of its total
assets (including the amount borrowed), less all liabilities and indebtedness
other than the borrowings and may use the proceeds of such borrowings for
investment purposes. The Fund will borrow for investment purposes only when the
Sub-adviser believes that such borrowings will benefit the Fund after taking
into account considerations such as the costs of the borrowing and the likely
investment returns on the securities purchased with the borrowed monies.
    
 
   
Borrowing for investment purposes is known as leveraging, which is a speculative
practice. Such borrowing by the Fund creates the opportunity for increased net
income and appreciation but, at the same time, involves special risk
considerations. For example, leveraging might exaggerate changes in the net
asset value of Fund shares and in the yield realized by the Fund. Although the
principal amount of such borrowings will be fixed, the Fund's assets may change
in value during the time the borrowing is outstanding. By leveraging the Fund,
changes in net asset values, higher or lower, may be greater in degree than if
leverage was not employed. To the extent the income derived from the assets
obtained with borrowed funds exceeds the interest and other expenses that the
Fund will have to pay, the Fund's net income will be greater than if borrowing
was not used. Conversely, if the income from the assets obtained with borrowed
funds is not sufficient to cover the cost of borrowing, the net income of the
Fund will be less than if borrowing were not used, and therefore the amount
available for distribution to shareholders as dividends will be reduced. The
Fund expects that some of its borrowings may be made on a secured basis.
    
 
   
In addition to the foregoing borrowings, the Fund may borrow money for temporary
or emergency purposes or payments in an amount not exceeding 5% of the value of
its total assets (not including the amount borrowed) provided that the total
amount borrowed by the Fund for any purpose does not exceed 33 1/3% of its total
assets.
    
 
   
The Fund may also enter into reverse repurchase agreements with a bank or
recognized securities dealer, although the Fund currently has no intention of
doing so with respect to more than 5% of its total assets. Under a reverse
repurchase agreement, the Fund would sell securities and agree to repurchase
them at a particular price at a future date. At the time the Fund enters into a
reverse repurchase agreement, it will establish and maintain a segregated
account with an approved custodian containing cash or liquid securities having a
value not less than the repurchase price, including accrued interest. Reverse
repurchase agreements involve the risk that the market value of the securities
retained in lieu of sale by the Fund may decline below the price of the
securities the Fund has sold but is obligated to repurchase. In the event the
buyer of securities under a reverse repurchase agreement files for bankruptcy or
becomes insolvent, such buyer or its trustee or receiver may receive an
extension of time to determine whether to enforce the Fund's obligation to
repurchase the securities, and the Fund's use of the proceeds of the reverse
repurchase agreement may effectively be restricted pending such decision.
    
 
   
The Fund also may enter into "dollar rolls," in which the Fund sells fixed
income securities for delivery
    
 
                               Prospectus Page 10
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
in the current month and simultaneously contracts to repurchase substantially
similar (same type, coupon and maturity) securities on a specified future date.
During the roll period, the Fund would forego principal and interest paid on
such securities. The Fund would be compensated by the difference between the
current sales price and the forward price for the future purchase, as well as by
the interest earned on the cash proceeds of the initial sale. See "Investment
Objectives and Policies" in the Statement of Additional Information.
    
 
   
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Fund's assets for purposes of calculating compliance
with the Fund's borrowing limitation. See "Investment Limitations" in the
Statement of Additional Information.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. At all times a loan is outstanding, the Fund requires the
borrower to maintain with the Fund's custodian, collateral consisting of cash,
U.S. government securities, or certain irrevocable letters of credit equal to at
least the value of the borrowed securities, plus any accrued interest or such
other collateral as permitted by the Fund's investment program and regulatory
agencies, and as approved by the Board. The Fund limits its loans of portfolio
securities to an aggregate of 30% of the value of its total assets, measured at
the time any such loan is made. The risks in lending portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional collateral or in recovery of the loaned securities and possible loss
of rights in the collateral should the borrower fail financially.
    
 
   
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. It also may invest in zero
coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
interest in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the "interest" on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
must be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
SYNTHETIC SECURITY POSITIONS. The Fund may utilize combinations of futures on
bonds and forward currency contracts to create investment positions that have
substantially the same characteristics as bonds of the same type as those on
which the futures contracts are written. Investment positions of this type are
generally referred to as "synthetic securities."
    
 
   
For example, in order to establish a synthetic security position for the Fund
that is comparable to owning a Japanese government bond, the Sub-adviser might
purchase futures contracts on Japanese government bonds in the desired principal
amount and purchase forward currency contracts for Japanese Yen in an amount
equal to the then current purchase price for such bonds in the Japanese cash
market, with each contract having approximately the same delivery date.
    
 
   
The Sub-adviser might roll over the futures and forward currency contract
positions before taking delivery in order to continue the Fund's investment
position, or the Sub-adviser might close out those positions, thus effectively
selling the synthetic security. Further, the amount of each contract might be
adjusted in response to market conditions and the forward currency contract
might be changed in amount or eliminated in order to hedge against currency
fluctuations.
    
 
   
The Sub-adviser would create synthetic security positions for the Fund when it
believes that it can obtain a better yield or achieve cost savings in comparison
to purchasing actual bonds or when comparable bonds are not readily available in
the market. Synthetic security positions are subject to the risk that changes in
the value of purchased futures contracts may differ from changes in the
    
 
                               Prospectus Page 11
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
value of the bonds that might otherwise have been purchased in the cash market.
Also, while the Sub-adviser believes that the cost of creating synthetic
security positions generally will be materially lower than the cost of acquiring
comparable bonds in the cash market, the Fund will incur transaction costs in
connection with each purchase of a futures or forward currency contract. The use
of futures contracts and forward currency contracts to create synthetic security
positions also is subject to substantially the same risks as those that exist
when these instruments are used in connection with hedging strategies. See
"Options, Futures and Forward Currency Transactions" below and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies, and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the Fund's investment. The Fund also may enter into interest
rate, currency and index swaps and purchase or sell related caps, floors and
collars and other similar instruments. See "Swaps, Caps, Floors and Collars"
below. These instruments are often referred to as "derivatives," which may be
defined as financial instruments whose performance is derived, at least in part,
from the performance of another asset (such as a security, currency or an index
of securities). The Fund may enter into such instruments up to the full value of
its portfolio assets. See "Risk Factors -- Options, Futures and Currency
Transactions" herein and "Options, Futures and Currency Strategies" in the
Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund also may purchase and sell put and call
options on currencies, futures contracts on currencies and options on such
futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on securities
to hedge against the risk of fluctuations in the prices of securities held by
the Fund or that the Sub-adviser intends to include in the Fund's portfolio. The
Fund also may purchase and sell put and call options on indices to hedge against
overall fluctuations in the securities markets generally or in a specific market
sector.
    
 
   
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or market sector decline that could adversely affect the Fund's
portfolio. The Fund also may purchase index futures contracts and purchase call
options or write put options on such contracts to hedge against a general market
or market sector advance and thereby attempt to lessen the cost of future
securities acquisitions. The Fund may use interest rate futures contracts and
options thereon to hedge its portfolio against changes in the general level of
interest rates.
    
 
   
SWAPS, CAPS, FLOORS AND COLLARS. The Fund may enter into interest rate, currency
and index swaps, and purchase or sell related caps, floors and collars and other
derivative instruments. The Fund expects to enter into these transactions
primarily to preserve a return or spread on a particular investment or portion
of its portfolio, to protect against currency fluctuations, as a technique for
managing the portfolio's duration (I.E., the price sensitivity to changes in
interest rates) or to protect against any increase in the price of securities
the Fund anticipates purchasing at a later date. The Fund intends to use these
transactions as hedges, and will not sell interest rate caps or floors if it
does not own securities or other instruments providing an income stream roughly
equivalent to what the Fund may be obligated to pay.
    
 
   
Interest rate swaps involve the exchange by the Fund with another party of their
respective commitments to pay or receive interest (for example, an exchange of
floating rate payments for fixed rate payments) with respect to a notional
amount of principal. A currency swap is an agreement to exchange cash flows on a
notional amount based on changes in the values of the reference indices.
    
 
The purchase of a cap entitles the purchaser to receive payments on a notional
principal amount from the party selling the cap to the extent that a specified
index exceeds a predetermined interest rate. The purchase of an interest rate
floor entitles the purchaser to receive payments on a notional principal amount
from the party selling the floor to the extent that a specified index falls
below a predetermined interest rate or amount. A collar is a
 
                               Prospectus Page 12
<PAGE>
                           AIM STRATEGIC INCOME FUND
combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
   
INDEXED COMMERCIAL PAPER. The Fund may invest without limitation in commercial
paper which is indexed to certain specific foreign currency exchange rates. The
terms of such commercial paper provide that its principal amount is adjusted
upwards or downwards (but not below zero) at maturity to reflect changes in the
exchange rate between two currencies while the obligation is outstanding. The
Fund will purchase such commercial paper with the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency, but the amount of principal payable by the issuer at
maturity will change in proportion to the change (if any) in the exchange rate
between the two specified currencies between the date the instrument is issued
and the date the instrument matures. While such commercial paper entails the
risk of loss of principal, the potential for realizing gains as a result of
changes in foreign currency exchange rates enables the Fund to hedge against a
decline in the U.S. dollar value of investments denominated in foreign
currencies while seeking to provide an attractive money market rate of return.
The Fund will not purchase such commercial paper for speculation.
    
 
   
OTHER INDEXED SECURITIES. The Fund may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of other
securities, securities indices, currencies, precious metals or other
commodities, or other financial indicators. Indexed securities typically, but
not always, are debt securities or deposits whose value at maturity or coupon
rate is determined by reference to a specific instrument or statistic. The
performance of indexed securities depends to a great extent on the performance
of the security, currency, or other instrument to which they are indexed, and
may also be influenced by interest rate changes in the United States and abroad.
At the same time, indexed securities are subject to the credit risks associated
with the issuer of the security, and their values may decline substantially if
the issuer's creditworthiness deteriorates. Indexed securities may be more
volatile than the underlying instruments. New forms of indexed securities
continue to be developed. The Fund may invest in such securities to the extent
consistent with its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. The
Fund's other investment policies described herein and in the Statement of
Additional Information may be changed by the Trust's Board of Trustees without
shareholder approval.
    
 
   
The Fund is authorized to make short sales of securities, although it has no
current intention of doing so. See "Investment Objectives and Policies -- Short
Sales" in the Statement of Additional Information.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objectives. The Fund's net asset value will fluctuate, reflecting fluctuations
in the market value of its portfolio positions and its net currency exposure.
The value of fixed income securities held by the Fund generally fluctuates
inversely with interest rate movements. Longer term bonds held by the Fund are
subject to greater interest rate risk.
    
 
   
NON-DIVERSIFIED CLASSIFICATION. The Fund is classified under the Investment
Company Act of 1940 (the "1940 Act") as a "non-diversified" fund. As a result,
the Fund will be able to invest in a fewer number of issuers than if it were
classified under the 1940 Act as a "diversified" fund. To the extent that the
Fund invests in a smaller number of issuers, the value of the Fund's shares may
fluctuate more widely and the Fund may be subject to greater investment and
credit risk with respect to its portfolios.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies. In addition, certain costs
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Fund's interest and dividends from foreign
issuers may be subject to non-U.S. withholding taxes, thereby reducing their net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the investments of the Fund in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
CURRENCY RISK. Since the Fund normally invests substantially in securities
denominated in currencies other than the U.S. dollar, and because they may hold
foreign currencies, they will be affected favorably or unfavorably by exchange
control regulations or changes in the exchange rates between such currencies and
the U.S. dollar. Changes in currency exchange rates will influence the value of
the Fund's shares, and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by the Fund. Currencies
generally are evaluated on the basis of fundamental economic criteria (e.g.,
relative inflation and interest rate levels and trends, growth rate forecasts,
balance of payments status and economic policies) as well as technical and
political data. The exchange rates between the U.S. dollar and other currencies
are determined by supply and demand in the currency exchange markets, the
international balance of payments, governmental intervention, speculation and
other economic and political conditions. If the currency in which a security is
denominated appreciates against the U.S. dollar, the dollar value of the
security will increase. Conversely, a decline in the exchange rate of the
currency would adversely affect the value of the security expressed in U.S.
dollars.
    
 
In addition, many of the currencies in emerging market countries have
experienced steady devaluations relative to the U.S. dollar and major
devaluations have historically occurred in certain countries.
 
   
INVESTING IN EMERGING MARKETS. Because of the special risks associated with
investing in emerging markets, an investment in the Fund should be considered
speculative. Investors are strongly advised to consider carefully the special
risks involved in emerging markets, which are in addition to the usual risks of
investing in developed foreign markets around the world.
    
 
                               Prospectus Page 14
<PAGE>
                           AIM STRATEGIC INCOME FUND
 
   
Investing in emerging markets involves risks relating to potential political and
economic instability within such markets and the risks of expropriation,
nationalization, confiscation of assets and property or the imposition of
restrictions on foreign investment and on repatriation of capital invested. In
the event of such expropriation, nationalization or other confiscation in any
emerging market, the Fund could lose its entire investment in that market.
    
 
Many emerging market countries have experienced substantial, and in some periods
extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain emerging market
countries.
 
Economies in emerging markets generally are dependent heavily upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values and other protectionist measures imposed or negotiated by the countries
with which they trade. These economies also have been and may continue to be
affected adversely by economic conditions in the countries in which they trade.
 
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
United States and other more developed countries. Disclosure and regulatory
standards in many respects are less stringent than in the United States and
other major markets. There also may be a lower level of monitoring and
regulation of emerging securities markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
 
   
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Fund to make intended securities purchases due to settlement
problems could cause the Fund to forego attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems could
result in losses to the Fund due to subsequent declines in value of the
portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.
    
 
   
The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading of securities may cease or may be
substantially curtailed and prices for the Fund's portfolio securities in such
markets may not be readily available. Section 22(e) of the 1940 Act permits a
registered investment company to suspend redemption of its shares for any period
during which an emergency exists, as determined by the SEC. Accordingly, when
the Fund believes that appropriate circumstances warrant, it will promptly apply
to the SEC for a determination that an emergency exists within the meaning of
Section 22(e) of the 1940 Act. During the period commencing from the Fund's
identification of such conditions until the date of SEC action, the portfolio
securities of the Fund in the affected markets will be valued at fair value as
determined in good faith by or under the direction of the Trust's Board of
Trustees.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The yield characteristics of
mortgage-backed and asset-backed securities differ from those of traditional
bonds. Among the major differences are that interest and principal payments are
made more frequently (usually monthly) and that principal may be prepaid at any
time because the underlying mortgage loans or other assets generally may be
prepaid at any time. Generally, prepayments on fixed-rate mortgage loans will
increase during a period of falling interest rates and decrease during a period
of rising interest rates. Mortgage-backed and asset-backed securities may also
decrease in value as a result of increasing market interest rates and, because
of prepayments, may benefit less than other bonds from declining interest rates.
Reinvestments of prepayments may occur at lower interest rates than the original
investment, thus adversely affecting the yield of the Fund. Actual prepayment
experience may cause the yield of a mortgage-backed security to differ from what
was assumed when the Fund purchased the security. The market for privately
issued mortgage-backed and asset-backed securities is smaller and less liquid
than the market for U.S. government mortgage-backed securities.
    
 
Foreign mortgage-backed securities markets are substantially smaller than U.S.
markets, but have been established in several countries, including Germany,
Denmark, Sweden, Canada and Australia,
 
                               Prospectus Page 15
<PAGE>
                           AIM STRATEGIC INCOME FUND
and may be developed elsewhere. Foreign mortgage-backed securities generally are
structured similar to domestic mortgage-backed securities, and they normally
present substantially similar investment risks as well as the other risks
normally associated with foreign securities.
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may have difficulty disposing of
Assignments and Participations. The liquidity of such securities is limited and,
the Fund anticipates that such securities could be sold only to a limited number
of institutional investors. The lack of a liquid secondary market could have an
adverse impact on the value of such securities and on the Fund's ability to
dispose of particular Assignments or Participations when necessary to meet the
Fund's liquidity needs or in response to a specific economic event, such as a
deterioration in the creditworthiness of the borrower. The lack of a liquid
secondary market for Assignments and Participations also may make it more
difficult for the Fund to assign a value to those securities for purposes of
valuing the Fund's portfolio and calculating its net asset value.
    
 
   
SOVEREIGN DEBT. The Fund may invest in sovereign debt securities of emerging
market governments, including Brady Bonds. Investments in such securities
involve special risks. The issuer of the debt or the governmental authorities
that control the repayment of the debt may be unable or unwilling to repay
principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn the Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's investments.
Emerging markets are faced with social and political issues and some of them
have experienced high rates of inflation in recent years and have extensive
internal debt. Among other effects, high inflation and internal debt service
requirements may adversely affect the cost and availability of future domestic
sovereign borrowing to finance governmental programs, and may have other adverse
social, political and economic consequences. Political changes or a
deterioration of a country's domestic economy or balance of trade may affect the
willingness of countries to service their sovereign debt. Although the
Sub-adviser intends to manage the Fund in a manner that will minimize the
exposure to such risks, there can be no assurance that adverse political changes
will not cause the Fund to suffer a loss of interest or principal on any of its
holdings.
    
 
   
In recent years, some of the emerging market countries in which the Fund expects
to invest have encountered difficulties in servicing their sovereign debt
obligations. Some of these countries have withheld payments of interest and/or
principal of sovereign debt. These difficulties have also led to agreements to
restructure external debt obligations -- in particular, commercial bank loans,
typically by rescheduling principal payments, reducing interest rates and
extending new credits to finance interest payments on existing debt. In the
future, holders of emerging market sovereign debt securities may be requested to
participate in similar rescheduling of such debt. Certain emerging market
countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by
    
 
                               Prospectus Page 16
<PAGE>
                           AIM STRATEGIC INCOME FUND
which a creditor may collect in whole or in part sovereign debt on which an
emerging market government has defaulted.
 
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
 
   
Investors should also be aware that certain sovereign debt instruments in which
the Fund may invest involve great risk. As noted above, sovereign debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to securities rated below investment grade by
Moody's and S&P. Such securities are regarded as predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligations and involve major risk exposure to
adverse conditions. Some of such securities, with respect to which the issuer
currently may not be paying interest or may be in payment default, may be
comparable to securities rated D by S&P or C by Moody's. The Fund may have
difficulty disposing of and valuing certain sovereign debt obligations because
there may be a limited trading market for such securities. Because there is no
liquid secondary market for many of these securities, the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors.
    
 
   
LOWER QUALITY DEBT SECURITIES. Under normal market conditions the Fund may
invest up to 50% of its total assets in debt securities rated below investment
grade. Such investments involve a high degree of risk.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest quality debt that is not in default as to
principal or interest and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than higher quality securities with regard to a deterioration of general
economic conditions. These securities are the equivalent of high yield, high
risk bonds, commonly known as "junk bonds." As noted above, the Fund may invest
in debt securities rated below C, which are in default as to principal and/or
interest.
    
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit quality in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Appendix A" for a discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
                               Prospectus Page 17
<PAGE>
                           AIM STRATEGIC INCOME FUND
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Fund. If an issuer exercises these provisions in a declining
interest rate market, the Fund may have to replace the security with a lower
yielding security, resulting in a decreased return for investors. In addition,
the Fund may have difficulty disposing of lower quality securities because there
may be a thin trading market for such securities. There may be no established
retail secondary market for many of these securities, and the Fund anticipates
that such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing the securities in the portfolios of the Fund. Adverse publicity and
investor perceptions, whether or not based on fundamental analysis, may also
decrease the values and liquidity of lower quality securities, especially in a
thinly traded market. The Fund also may acquire lower quality debt securities
during an initial underwriting or may acquire lower quality debt securities
which are sold without registration under applicable securities laws. Such
securities involve special considerations and risks.
    
 
   
Factors having an adverse effect on the market value of lower rated securities
or their equivalents purchased by the Fund will adversely impact net asset value
of the Fund. See "Risk Factors" in the Statement of Additional Information. In
addition to the foregoing, such factors may include: (i) potential adverse
publicity; (ii) heightened sensitivity to general economic or political
conditions; and (iii) the likely adverse impact of a major economic recession.
The Fund also may incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in emerging markets can differ
from debt obligations issued by private entities in that remedies from defaults
generally must be pursued in the courts of the defaulting government, and legal
recourse is therefore somewhat diminished. Political conditions, in terms of a
government's willingness to meet the terms of its debt obligations, also are of
considerable significance. There can be no assurance that the holders of
commercial bank debt may not contest payments to the holders of debt securities
issued by governments in emerging markets in the event of default by the
governments under commercial bank loan agreements.
    
 
   
As of October 31, 1997, the Fund had 89.27% of its total net assets in debt
securities that received a rating from Moody's and 4.00% of its total net assets
in debt securities that were not so rated. In addition, the Fund had 6.73% of
its total net assets in cash and net receivables. The Fund had the following
percentages of its total net assets invested in rated securities: Aaa -- 41.23%,
Aa -- 12.68%, A -- 1.31%, Baa -- 3.75%, Ba -- 24.30%, B -- 6.00%, Caa -- 0.00%,
Ca -- 0.00%, C -- 0.00%. Included under the unrated category are securities held
by the Fund which, while unrated, have been determined by the Sub-adviser to be
of comparable quality to securities in the following rating categories: Ba --
1.03%; and B -- 2.97%. It should be noted that the allocation of the investments
of the Fund by rating on any given date will vary and should not be considered
representative of the future portfolio composition of the Fund.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. In addition, issuers in
emerging markets typically are subject to a greater degree of change in earnings
and business prospects than issuers in developed countries. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Fund invests; (4) lack of
assurance that a liquid secondary market will exist for any particular option,
futures contract or option thereon at any particular time; (5) the possible loss
of principal under certain conditions; and (6) the possible inability of the
Fund to purchase or sell a portfolio security at a time when it would otherwise
be favorable for it to do so, or the possible need for the Fund to sell a
security at a disadvantageous

time, due to the need for the Fund or Portfolio to maintain "cover" or to set
aside securities in connection with hedging transactions.
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets, in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust and persons or companies furnishing services to the Fund
including the investment management and administration agreement with AIM, the
investment sub-advisory and sub-administration agreement between AIM and the
Sub-adviser, the agreements with AIM Distributors regarding distribution of the
Fund's shares, the custody agreement and the transfer agency agreement. The
day-to-day operations of the Fund are delegated to the officers of the Trust,
subject always to the investment objectives and policies of the Fund and to the
general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trustees of the Trust.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the investment portfolio of
the Fund and placing orders to buy, sell or hold particular securities. In
addition, AIM and the Sub-adviser provide the following administration services
to the Fund: furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Fund's operation.
    
 
   
The Fund pays AIM investment management and administration fees computed daily
and payable monthly, based on the average daily net assets, for such services at
the annualized rate of .725% on the first $500 million, .70% on the next $1
billion, .675% on the next $1 billion, and .65% on amounts thereafter. Out of
the aggregate fees payable by the Fund, AIM pays the Sub-adviser sub-advisory
and sub-administration fees equal to 40% of the aggregate fees AIM receives from
the Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or any other agents. AIM has
undertaken to limit the expenses of the Class A and Class B shares of the Fund
(exclusive of brokerage commissions, taxes, interest and extraordinary expenses)
to the maximum annual rate of 1.85% and 2.50% of the average daily net assets of
the Fund's Class A and Class B shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29,

1998, Liechtenstein Global Trust AG ("LGT"), the former indirect parent
organization of the Sub-adviser, consummated a purchase agreement with AMVESCAP
PLC pursuant to which AMVESCAP PLC acquired LGT's Asset Management Division,
which included the Sub-adviser and certain other affiliates. As a result of this
transaction, the Sub-adviser is now an indirect wholly owned subsidiary of
AMVESCAP PLC. Prior to the sale, the Sub-adviser and its worldwide asset
management affiliates provided investment management and/or administrative
services to institutional, corporate and individual clients around the world

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions for the Fund may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."

                           AIM STRATEGIC INCOME FUND
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 on behalf of Class A shares of the Fund, and has entered into a
Master Distribution Agreement, dated May 29, 1998, on behalf of Class B shares
of the Fund (individually referred to as a "Distribution Agreement" or
collectively as the "Distribution Agreements") with AIM Distributors, a
registered broker-dealer and a wholly owned subsidiary of AIM, to act as the
distributor of Class A and Class B shares of the Fund. Certain Trustees and
officers of the Trust are affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute shares of the Fund directly and through institutions with whom AIM
Distributors has entered into selected dealer agreements. Under the Distribution
Agreement for the Class B shares, AIM Distributors sells Class B shares of the
Fund at net asset value subject to a contingent deferred sales charge
established by AIM Distributors. AIM Distributors is authorized to advance to
institutions through whom Class B shares are sold a sales commission under
schedules established by AIM Distributors. The Distribution Agreement for the
Class B shares provides that AIM Distributors (or its assignee or transferee)
will receive 0.75% (of the total 1.00% payable under the distribution plan
applicable to Class B shares) of the Fund's average daily net assets
attributable to Class B shares attributable to the sales efforts of AIM
Distributors. In the event the Class B shares Distribution Agreement is
terminated, AIM Distributors would continue to receive payments of asset based
sales charges in respect of the outstanding Class B shares attributable to the
distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B shares master distribution plan (as defined in the
plan) would terminate all payments to AIM Distributors. Termination of the Class
B shares distribution plan or Distribution Agreement does not affect the
obligation of Class B shareholders to pay contingent deferred sales charges.
    
 
   
DISTRIBUTION PLANS. CLASS A PLAN. The Trust has adopted a Master Distribution
Plan applicable to Class A shares of the Fund (the "Class A Plan") pursuant to
Rule 12b-1 under the 1940 Act, to compensate AIM Distributors for the purpose of
financing any activity that is intended to result in the sale of Class A shares
of the Fund.
    
 
   
Under the Class A Plan, the Trust may compensate AIM Distributors an aggregate
amount of 0.35% of the average daily net assets of Class A shares of the Fund on
an annualized basis.
    
   
The Class A Plan is designed to compensate AIM Distributors, on a quarterly
basis, for certain promotional and other sales-related costs, and to implement a
dealer incentive program which provides for periodic payments to selected
dealers who furnish continuing personal shareholder services to their customers
who purchase and own Class A shares of the Fund. Payments can also be directed
by AIM Distributors to selected institutions who have entered into service
agreements with respect to Class A shares of the Fund and who provide continuing
personal services to their customers who own Class A shares of the Fund. The
service fees payable to selected institutions are calculated at the annual rate
of 0.25% of the average daily net asset value of those Fund shares that are held
in such institution's customers' accounts which were purchased on or after a
prescribed date set forth in the Plan.
    
 
   
Of the aggregate amount payable under the Class A Plan, payments to dealers and
other financial institutions that provide continuing personal shareholder
services to their customers who purchase and own shares of the Fund, in amounts
of up to 0.25% of the average net assets of the Fund attributable to the
customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A Plan. The Class A Plan also
imposes a cap on the total amount of sales charges, including asset-based sales
charges, that may be paid by the Trust with respect to the Fund. The Class A
Plan does not obligate the Fund to reimburse AIM Distributors for the actual
expenses AIM Distributors may incur in fulfilling its obligations under the
Class A Plan on behalf of the Fund. Thus, under the Class A Plan, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Fund will not be obligated to pay more than
that fee. If AIM Distributors' expenses are less than the fee it receives, AIM
Distributors will retain the full amount of the fee. Payments pursuant to the
Plans are subject to any applicable limitations imposed by rules of the National
Association of Securities Dealers, Inc.
    
 
   
CLASS B PLAN. The Trust has also adopted a master distribution plan applicable
to Class B shares of the Fund (the "Class B Plan"). Under the Class B
    
 
                               Prospectus Page 21
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
Plan, the Fund pays distribution expenses at an annual rate of 1.00% of the
average daily net assets attributable to the Fund's Class B shares. Of such
amount the Fund pays a service fee of 0.25% of the average daily net assets
attributable to the Fund's Class B shares to selected dealers and financial
institutions who furnish continuing personal shareholder services to their
customers who purchase and own Class B shares of the Fund. Any amounts not paid
as a service fee would constitute an asset-based sales charge. Amounts paid in
accordance with the Class B Plan with respect to the Fund may be used to finance
any activity primarily intended to result in the sale of Class B shares of the
Fund.
    
 
   
BOTH PLANS. Activities that may be financed under the
Class A Plan and the Class B Plan (collectively, the "Plans") include, but are
not limited to: printing of prospectuses and statements of additional
information and reports for other than existing shareholders, overhead,
preparation and distribution of advertising material and sales literature,
expense of organizing and conducting sales seminars, supplemental payments to
dealers and other institutions such as asset-based sales charges or as payments
of service fees under shareholder service arrangements, and the cost of
administering the Plans. These amounts payable by the Fund under the Plans need
not be directly related to the expenses actually incurred by AIM Distributors on
behalf of the Fund. Thus, even if AIM Distributors' actual expenses exceed the
fee payable to AIM Distributors thereunder at any given time, the Trust will not
be obligated to pay more than that fee, and if AIM Distributors' expenses are
less than the fee it receives, AIM Distributors will retain the full amount of
the fee. Payments pursuant to the Plans are subject to any applicable
limitations imposed by rules of the National Association of Securities Dealers,
Inc.
    
 
   
Each of the Plans may be terminated at any time by a vote of the majority of
those Trustees who are not "interested persons" of the Trust or by a vote of the
holders of the majority of the outstanding shares of the applicable class.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its 12b-1 fee, while retaining its
ability to be reimbursed for such fee prior to the end of each fiscal year.
    
 
   
Under the Plans, certain financial institutions which have entered into service
agreements and which sell shares of the Fund on an agency basis, may receive
payments from the Fund pursuant to the respective Plans. AIM Distributors does
not act as principal, but rather as agent, for the Fund in making such payments.
The Fund will obtain a representation from such financial institutions that they
will either be licensed as dealers as required under applicable state law, or
that they will not engage in activities which would constitute acting as a
"dealer" as defined under applicable state law. Financial intermediaries and any
other person entitled to receive compensation for selling Fund shares may
receive different compensation for selling shares of one class over another.
    
 
   
For additional information concerning the operation of the Plans see the
Statement of Additional Information.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust.
    
 
   
From time to time, the Trust may establish other funds, each corresponding to a
distinct investment portfolio and a distinct series of the Trust's shares.
Shares of each fund are entitled to one vote per share (with proportional voting
for fractional shares) and are freely transferable. Shareholders have no
preemptive rights. Other than the automatic conversion of Class B shares to
Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may also
issue an unlimited number of shares of the Fund. Each share of the Fund
represents an interest in the Fund only, has a par value of $0.01 per share,
represents an equal proportionate interest in the Fund with other shares of the
Fund and is entitled to such dividends and distributions out of the income
earned and gain realized on the assets belonging to the Fund as may be declared
by the Board of Trustees. Each share of the Fund is equal in earnings, assets
and voting privileges except that each class normally has exclusive voting
rights with respect to its distribution plan and bears the expenses, if any,
related to the distribution of its shares. Shares of the Fund, when issued, are
fully paid and nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

                                   APPENDIX A
                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from "Aaa" to "C." Investment grade ratings are the first
four categories:
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered as well-assured. Often the protection of
    interest and principal payments may be very moderate, and thereby not well
    safeguarded during both good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B -- Bonds which are rated B generally lack characteristics of the
    desirable investment. Assurance of interest and principal payments or of
    maintenance of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa are of poor standing. Such issues may
    be in default or there may be present elements of danger with respect to
    principal or interest.
 
        Ca -- Bonds which are rated Ca represent obligations which are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are rated C are the lowest rated class of bonds, and
    issues so rated can be regarded as having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.

<PAGE>
                           AIM STRATEGIC INCOME FUND
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various entities in categories ranging from "AAA"
to "D" according to quality. Investment grade ratings are the first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations rated "BB," "B," "CCC," "CC," and "C"
    are regarded as having significant speculative characteristics. "BB"
    indicates the least degree of speculation and "C" the highest. While such
    obligations will likely have some quality and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An obligation rated "BB" is less vulnerable to nonpayment than
    other speculative issues. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate capacity to meet its financial commitment
    on the obligation.
 
        B -- An obligation rated "B" is more vulnerable to nonpayment than
    obligations rated "BB," but the obligor currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its financial commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to have the capacity to meet its financial commitment on the
    obligation.
 
        CC -- An obligation rated "CC" is currently highly vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed or similar action has been taken, but payments on
    this obligation are being continued.
 
        D -- An obligation rated "D" is in payment default. The "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the applicable grace period has not expired, unless S&P believes
    that such payments will be made during such grace period. The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally will be evidenced by many of
the characteristics cited above but to a lesser degree. Earnings trends and
coverage ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

below under "Special Information Relating to Multiple Class Funds." For

    There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
    ALL GROUPS OF AIM FUNDS.  AIM Distributors may elect to re-allow the entire
initial sales charge to dealers for all sales with respect to which orders are
placed with AIM Distributors during a particular period. Dealers to whom
substantially the entire sales charge is re-allowed may be deemed to be
"underwriters" as that term is defined under the Securities Act of 1933.
 
    In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
payments or other consideration shall not exceed 0.25% of the public offering
price of the shares sold. Any such bonus or incentive programs will not change
the price paid by investors for the purchase of the applicable AIM Fund's shares
or the amount that any particular AIM Fund will receive as proceeds from such
sales. Dealers may not use sales of the AIM Funds' shares to qualify for any
incentives to the extent that such incentives may be prohibited by the laws of
any state.
 
    AIM Distributors may make payments to dealers and institutions who are
dealers of record for purchases of $1 million of more of Class A shares (or
shares which normally involve payment of initial sales charges), which are sold
at net asset value and are subject to a contingent deferred sales charge, for
all AIM Funds other than Class A shares of each of AIM LIMITED MATURITY TREASURY
FUND and AIM TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million
of such purchases, plus 0.80% of the next $1 million of such purchases, plus
0.50% of the next $17 million of such purchases, plus 0.25% of amounts in excess
of $20 million of such purchases. See "Contingent Deferred Sales Charge Program
for Large Purchases." AIM Distributors may make payments to dealers and
institutions who are dealers of record for purchases of $1 million or more of
Class A shares (or shares which normally involve payment of initial sales
charges), and which are sold at net asset value and are not subject to a
contingent deferred sales charge, in an amount up to 0.10% of such purchases of
Class A shares of AIM LIMITED MATURITY TREASURY FUND, and in an amount up to
0.25% of such purchases of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class B shares of the AIM Funds at the time of such sales. Payments with
respect to Class B shares will equal 4.00% of the purchase price of the Class B
shares sold by the dealer or institution, and will consist of a sales commission
equal to 3.75% of the purchase price of the Class B shares sold plus an advance
of the first year service fee of 0.25% with respect to such shares. The portion
of the payments to AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
   
    AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds at the time of such sales. Payments with
respect to Class C shares will equal 1.00% of the purchase price of the Class C
shares sold by the dealer or institution, and will consist of a sales commission
of 0.75% of the purchase price of the Class C shares sold plus an advance of the
first year service fee of 0.25% with respect to such shares. AIM Distributors
will retain all payments received by it relating to Class C shares for the first
year after they are purchased. The portion of the payments to AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly to dealers and institutions based on the average net asset
value of Class C shares which are attributable to shareholders for whom the
dealers and institutions are designated as dealers of record. These commissions
on Class C shares are not paid on sales to investors exempt from the CDSC,
including Class C shareholders of record on April 30, 1995 who purchase
additional shares in any of the Funds on or after May 1, 1995, and in
circumstances where AIM Distributors grants an exemption on particular
transactions.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of regular trading on the New York Stock Exchange ("NYSE"), which is
generally 4:00 p.m. Eastern Time (and which is hereinafter referred to as "NYSE
Close"), on any business day of an AIM Fund will be confirmed at the price next
determined. Orders received after NYSE Close will be confirmed at the price
determined on the next business day of the AIM Fund. Certain financial
institutions (or their designees) may be authorized to accept purchase orders on
behalf of the AIM Funds. Orders received by authorized institutions (or their
designees) before NYSE Close will be deemed to have been received by an AIM Fund
on such day and will be effected that day, provided that such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. It is the responsibility of the dealer/financial institution to ensure
that all orders are transmitted on a timely basis to the Transfer Agent. Any
loss resulting from the dealer/financial institution's failure to submit an
order within the prescribed time frame will be borne by that dealer/financial
institution. Please see "How to Purchase Shares -- Purchases by Wire" for
information on obtaining a reference number for wire orders, which will
facilitate the handling of such orders and ensure prompt credit to an investor's
account. A "business day" of an AIM Fund is any day on which the NYSE is open
for business. It is expected that the NYSE will be closed
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
   
    SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS.  The Multiple Class
Funds currently offer two or more classes of shares through separate
distribution systems (the "Multiple Distribution System"). Although each class
of shares of a particular Multiple Class Fund represents an interest in the same
portfolio of investments, each class is subject to a different distribution
structure and, as a result, differing expenses. This Multiple Distribution
System allows investors to select the class that is best suited to the
investor's needs and objectives. In considering the options afforded by the
Multiple Distribution System, investors should consider both the applicable
initial sales charge or contingent deferred sales charge, as well as the ongoing
expenses borne by each class of shares and other relevant factors, such as
whether his or her investment goals are long-term or short-term.
    
 
   
    CLASS A SHARES generally are sold subject to the initial sales charges
    described above and are subject to the other fees and expenses described
    herein. Class A shares of AIM MONEY MARKET FUND are designed to meet the
    needs of an investor who wishes to establish a dollar cost averaging
    program, pursuant to which Class A shares an investor owns may be exchanged
    at net asset value for Class A shares of another Multiple Class Fund or
    shares of another AIM Fund which is not a Multiple Class Fund, subject to
    the terms and conditions described under the caption "Exchange Privilege --
    Terms and Conditions of Exchanges."
    
 
    CLASS B SHARES are sold without an initial sales charge. Thus, the entire
    purchase price of Class B shares is immediately invested in Class B shares.
    Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
    per annum on the average daily net assets of a Multiple Class Fund
    attributable to Class B shares. See the discussion under the caption
    "Management -- Distribution Plans." In addition, Class B shares redeemed
    within six years from the date such shares were purchased are subject to a
    contingent deferred sales charge ranging from 5% for redemptions made within
    the first year to 1% for redemptions made within the sixth year. No
    contingent deferred sales charge will be imposed if Class B shares are
    redeemed after six years from the date such shares were purchased.
    Redemptions of Class B shares and associated charges are further described
    under the caption "How to Redeem Shares -- Multiple Distribution System."
 
   
    Class B shares will automatically convert into Class A shares of the same
    Multiple Class Fund (together with a pro rata portion of all Class B shares
    acquired through the reinvestment of dividends and other distributions)
    eight years from the end of the calendar month in which the purchase of
    Class B shares was made. Class B shares of AIM GLOBAL TRENDS FUND that were
    outstanding on May 29, 1998 and which are continuously held by the
    shareholder, automatically convert to Class A shares of AIM GLOBAL TRENDS
    FUND seven years from the end of the calendar month in which the purchase of
    such Class B shares was made. If a shareholder exchanges Class B shares of
    AIM GLOBAL TRENDS FUND that were outstanding on, and continuously held
    since, May 29, 1998 for Class B shares of any other AIM Fund, such Class B
    shares will be subject to the eight year conversion feature applicable to
    Class B shares of all other AIM Funds. Following such conversion of their
    Class B shares, investors will be relieved of the higher Rule 12b-1 Plan
    payments associated with Class B shares. See "Management -- Distribution
    Plans."
    
 
   
    AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an initial
    sales charge and are not subject to a contingent deferred sales charge;
    however, they are subject to the other fees and expenses described in the
    prospectus for AIM MONEY MARKET FUND.
    
 
    TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY).  Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
Eastern Time or NYSE Close on any business day of the Fund will be confirmed at
the price next determined. Net asset value is normally determined at 12:00 noon
Eastern Time and NYSE Close on each business day of AIM MONEY MARKET FUND.
 
    SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND, AIM TAX-EXEMPT CASH
FUND and AIM DOLLAR FUND (THE "MONEY MARKET FUNDS").  Because each Money Market
Fund uses the amortized cost method of valuing the securities it holds and
rounds its per share net asset value to the nearest whole cent, it is
anticipated that the net asset value of the shares of such funds will remain
constant at $1.00 per share. However, there is no assurance that each Money
Market Fund can maintain a $1.00 net asset value per share. In order to earn
dividends with respect to AIM MONEY MARKET FUND on the same day that a purchase
is made, purchase payments in the form of federal funds must be received by the
Transfer Agent before 12:00 noon Eastern Time on that day. Purchases made by
payments in any other form, or payments in the form of federal funds received
after such time but prior to NYSE Close, will begin to earn dividends on the
next business day following the date of purchase. The Money Market Funds
generally will not issue share certificates but will record investor holdings in
noncertificate form and regularly advise the shareholder of his ownership
position.
 
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
   
    Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of Class A shares of the AIM Funds that
are otherwise subject to an initial sales charge, provided that such purchases
are made by a "purchaser" as hereinafter defined. Purchases of Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM DOLLAR FUND, AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and Class B and Class C shares of the Multiple Class Funds
will not be taken into account in determining whether a purchase qualifies for a
reduction in initial sales charges.
    
 
    The term "purchaser" means:
 
- - an individual and his or her spouse and children, including any trust
  established exclusively for the benefit of any such person; or a pension,
  profit-sharing, or other benefit plan established exclusively for the benefit
  of any such person, such as an IRA, Roth IRA, a single-participant
  money-purchase/profit-sharing plan or an individual participant in a 403(b)
  plan (unless such 403(b) plan qualifies as the purchaser as defined below);
 
- - a 403(b) plan, the employer/sponsor of which is an organization described
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the
  "Code"), provided that:
 
      a. the employer/sponsor must submit contributions for all participating
         employees in a single contribution transmittal (i.e., the funds will
         not accept contributions submitted with respect to individual
         participants);
 
      b. each transmittal must be accompanied by a single check or wire
         transfer; and
 
      c. all new participants must be added to the 403(b) plan by submitting an
         application on behalf of each new participant with the contribution
         transmittal;
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
 
- - a trustee or fiduciary purchasing for a single trust, estate or single
  fiduciary account (including a pension, profit-sharing or other employee
  benefit trust created pursuant to a plan qualified under Section 401 of the
  Code) and 457 plans, although more than one beneficiary or participant is
  involved;
 
   
- - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
  Simplified Employee Pension account ("SARSEP"), or Savings Incentive Match
  Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
  Distributors in writing that all of its related employee SEP, SARSEP or SIMPLE
  IRA accounts should be linked;
    
 
- - any other organized group of persons, whether incorporated or not, provided
  the organization has been in existence for at least six months and has some
  purpose other than the purchase at a discount of redeemable securities of a
  registered investment company; or
 
- - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
  Capital Management, Inc. ("AIM Capital").
 
    Investors or dealers seeking to qualify orders for a reduced initial sales
charge must identify such orders and, if necessary, support their qualification
for the reduced charge. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by virtue of the foregoing definition, to the reduced
sales charge. No person or entity may distribute shares of the AIM Funds without
payment of the applicable sales charge other than to persons or entities who
qualify for a reduction in the sales charge provided herein.
 
    (1) LETTERS OF INTENT.  A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). The LOI privilege is
also available to holders of the Connecticut General Guaranteed Account,
established for tax qualified group annuities, for contracts purchased on or
before June 30, 1992. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for (i) Class A
shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares
of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple
Class Funds) within the following 13 consecutive months. By marking the LOI
section on the account application and by signing the account application, the
purchaser indicates that he understands and agrees to the terms of the LOI and
is bound by the provisions described below.
 
   
    Each purchase of fund shares normally subject to an initial sales charge
made during the 13-month period will be made at the public offering price
applicable to a single transaction of the total dollar amount indicated by the
LOI, as described under "Sales Charges and Dealer Concessions." It is the
purchaser's responsibility at the time of purchase to specify the account
numbers that should be considered in determining the appropriate sales charge.
The offering price may be further reduced as described under "Rights of
Accumulation" if the Transfer Agent is advised of all other accounts at the time
of the investment. Shares acquired through reinvestment of dividends and capital
gain distributions will not be applied to the LOI. At any time during the
13-month period after meeting the original obligation, a purchaser may revise
his intended investment amount upward by submitting a written and signed
request. Such a revision will not change the original expiration date. By
signing an LOI, a purchaser is not making a binding commitment to purchase
additional shares, but if purchases made within the 13-month period do not total
the amount specified, the investor will pay the increased amount of sales charge
as described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase with the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
    
 
   
    To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). All dividends and any capital gain distributions on the escrowed shares
will be credited to the purchaser. All shares purchased, including those
escrowed, will be registered in the purchaser's name. If the total investment
specified under this LOI is completed within the 13-month period, the escrowed
shares will be promptly released. If the intended investment is not completed,
the purchaser will pay the Transfer Agent the difference between the sales
charge on the specified amount and the amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
    
 
                                      A-8
<PAGE>
                              AIM INVESTOR'S GUIDE
irrevocably constitutes and appoints the Transfer Agent as his attorney to
surrender for redemption any or all shares, to make up such difference within 60
days of the expiration date.
 
    If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. If at any
time before completing the LOI Program the purchaser requests the Transfer Agent
to liquidate or transfer beneficial ownership of his total shares, a
cancellation of the LOI will automatically be effected. If the total amount
purchased is less than the amount specified in the LOI, the Transfer Agent will
redeem an appropriate number of escrowed shares equal to the difference between
the sales charge actually paid and the sales charge that would have been paid if
the total purchases had been made at a single time.
 
   
    Any investor who purchased shares of the AIM/GT Funds pursuant to a LOI
entered into prior to June 1, 1998 may continue to make such purchases under the
terms of such LOI. See "How to Purchase and Redeem Shares" in the Statement of
Additional Information.
    
 
   
    (2) RIGHTS OF ACCUMULATION.  A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM DOLLAR FUND, AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM
MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) at the time of the proposed purchase. Rights of accumulation are also
available to holders of the Connecticut General Guaranteed Account, established
for tax-qualified group annuities, for contracts purchased on or before June 30,
1992. To determine whether or not a reduced initial sales charge applies to a
proposed purchase, AIM Distributors takes into account not only the money which
is invested upon such proposed purchase, but also the value of all shares of the
AIM Funds (except for (i) Class A shares of AIM DOLLAR FUND, AIM TAX-EXEMPT CASH
FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND and (ii) Class B and
Class C shares of the Multiple Class Funds) owned by such purchaser, calculated
at their then current public offering price. If a purchaser so qualifies for a
reduced sales charge, the reduced sales charge applies to the total amount of
money then being invested by such purchaser and not just to the portion that
exceeds the breakpoint above which a reduced sales charge applies. For example,
if a purchaser already owns qualifying shares of any AIM Fund with a value of
$20,000 and wishes to invest an additional $20,000 in a fund with a maximum
initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will
apply to the full $20,000 purchase and not just to the $15,000 in excess of the
$25,000 breakpoint. To qualify for obtaining the discount applicable to a
particular purchase, the purchaser or his dealer must furnish AFS with a list of
the account numbers and the names in which such accounts of the purchaser are
registered at the time the purchase is made.
    
 
   
    PURCHASES AT NET ASSET VALUE.  Purchases of shares of any of the AIM Funds
at net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and other distributions from
a fund (see "Dividends, Distributions and Tax Matters"); (b) exchanges of shares
of certain other funds (see "Exchange Privilege"); (c) use of the reinstatement
privilege (see "How to Redeem Shares"); or (d) a merger, consolidation or
acquisition of assets of a fund.
    
 
    Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.
 
    The following persons may purchase Class A shares of the AIM Funds through
AIM Distributors without payment of an initial sales charge: (a) A I M
Management Group Inc. ("AIM Management") and its affiliated companies; (b) any
current or retired officer, director, trustee or employee, or any member of the
immediate family (including spouse, children, parents and parents of spouse) of
any such person, of AIM Management or its affiliates or of certain mutual funds
which are advised or managed by AIM; or any trust established exclusively for
the benefit of such persons; (c) any employee benefit plan established for

the immediate family (including spouse, children, parents and parents of spouse)
of any such person, or of CIGNA Corporation or of any of its affiliated
companies, or of First Data Investor Services Group (formerly The Shareholder
Services Group, Inc.); (e) any investment company sponsored by CIGNA
Investments, Inc. or any of its affiliated companies for the benefit of its
directors' deferred compensation plans; (f) discretionary advised clients of AIM
or AIM Capital; (g) registered representatives and employees of dealers who have
entered into agreements with AIM Distributors (or financial institutions that
have arrangements with such dealers with respect to the sale of shares of the
AIM Funds) and any member of the immediate family (including spouse, children,
parents and parents of spouse) of any such person, provided that purchases at
net asset value are permitted by the policies of such person's employer; (h)
certain broker-dealers, investment advisers or bank trust departments that
provide asset allocation, similar specialized investment services or investment
company transaction services for their customers, that charge a minimum annual
fee for such services, and that have entered into an agreement with AIM
Distributors with respect to their use of the AIM Funds in connection with such
services; (i) any employee or any member of the immediate family (including
spouse, children, parents and parents of spouse) of any employee, of Triformis
Inc.; (j) shareholders of the AIM/GT Funds as of April 30, 1987 who since that
date continually have owned shares of one or more of the AIM/GT Funds; and (k)
certain former AMA Investment Advisers' shareholders who became shareholders of
the AIM Global Health Care Fund in October 1989, and who have continuously held
shares in the AIM/GT Funds since that time.
    
 
   
    In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined under the
caption "Exchange Privilege") sold at net asset value to an employee benefit
plan in accordance with this paragraph as follows: 1% of the first $2 million of
such purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50%
of the next $17 million of such purchases, plus 0.25% of amounts in excess of
$20 million of such purchases and up to 0.10% of the net asset value of any
Class A shares of AIM LIMITED MATURITY TREASURY FUND sold at net asset value to
an employee benefit plan in accordance with this paragraph.
    
 
    Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sales of Class A shares of
AIM WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such
trusts; and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone

                              AIM INVESTOR'S GUIDE
number of the dealer who sold to the unit holder the units to be redeemed or
repurchased; and (ii) states that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by the
proceeds from the redemption or repurchase of units of such trusts.
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
    Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
 
    SYSTEMATIC WITHDRAWAL PLAN.  Under a Systematic Withdrawal Plan, a
shareholder who owns shares which are not subject to a contingent deferred sales
charge, can arrange for monthly, quarterly or annual amounts (but not less than
$50) to be drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Under a Systematic Withdrawal Plan, all shares are to be held by the
Transfer Agent and all dividends and distributions are reinvested to shares of
the applicable AIM Fund by the Transfer Agent. To provide funds for payments
made under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient
full and fractional shares at their net asset value in effect at the time of
each such redemption.
 
   
    Payments under a Systematic Withdrawal Plan constitute taxable events. Since
such payments are funded by the redemption of shares, they may result in a
return of capital and in capital gains or losses, rather than in ordinary
income. Because sales charges are imposed on additional purchases of shares
(other than Class B or Class C shares of the Multiple Class Funds, and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
    
 
    The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.
 
    AUTOMATIC INVESTMENT PLAN.  Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan
withdrawal is made on the shareholder's bank account in
 
                                      A-11
<PAGE>
                              AIM INVESTOR'S GUIDE
the amount specified by the shareholder (minimum $50 per investment, per
account) and on a day or date(s) specified by the shareholder. The proceeds are
invested in shares of the designated AIM Fund at the applicable offering price
determined on the date of the withdrawal. An Automatic Investment Plan may be
discontinued upon 10 days' prior notice to the Transfer Agent or AIM
Distributors.
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions" for a description
of payment dates for these options. In order to qualify to have dividends and
distributions of one AIM Fund invested in shares of another AIM Fund, the
following conditions must be satisfied: (a) the shareholder must have an account
balance in the dividend paying fund of at least $5,000; (b) the account must be
held in the name of the shareholder (i.e., the account may not be held in
nominee name); and (c) the shareholder must have requested and completed an
authorization relating to the reinvestment of dividends into another AIM Fund.
An authorization may be given on the account application or on an authorization
form available from AIM Distributors. An AIM Fund will waive the $5,000 minimum
account value requirement if the shareholder has an account in the fund selected
to receive the dividends and distributions with a value of at least $500.
    
 
    DOLLAR COST AVERAGING.  Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sale charges may apply, as described under the caption
"Exchange Privilege."
 
   
    PROTOTYPE RETIREMENT PLANS.  The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination money-
purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans; SARSEP
plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement accounts").
Information concerning these plans, including the custodian's fees and the forms
necessary to adopt such plans, can be obtained by calling or writing the AIM
Funds or AIM Distributors. Shares of the AIM Funds are also available for
investment through existing 401(k) plans (for both individuals and employers)
adopted under the Code. The plan custodian currently imposes an annual $10
maintenance fee with respect to each retirement account for which it serves as
the custodian. This fee is generally charged in December. Each AIM Fund and/or
the custodian reserve the right to change this maintenance fee and to initiate
an establishment fee (not to exceed its cost).
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of AIM Funds. The Program automatically rebalances
holdings of AIM Funds to the established allocation on a periodic basis. Under
the Program, a shareholder may predesignate, on a percentage basis, how the
total value of his or her holdings in a minimum of two, and a maximum of ten,
AIM Funds ("Personal Portfolio") is to be rebalanced on a quarterly, semiannual,
or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more AIM Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other AIM Funds in the
    
 
                                      A-12
<PAGE>
                              AIM INVESTOR'S GUIDE
   
shareholder's Personal Portfolio. See "Exchange Privilege." If shares of the AIM
Fund(s) in a shareholder's Personal Portfolio have appreciated during a
rebalancing period, the Program will result in shares of AIM Fund(s) that have
appreciated most during the period being exchanged for shares of AIM Fund(s)
that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A
SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME
TAX PURPOSES. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions." Participation in the Program does not assure that a shareholder
will profit from purchases under the Program nor does it prevent or lessen
losses in a declining market.
    
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular AIM Fund would
be 2% or less. In predesignating percentages, shareholders must use whole
percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an AIM
Fund's shares. The AIM Funds and AIM Distributors reserve the right to modify,
suspend, or terminate the Program at any time on 60 days' prior written notice
to shareholders. A request to participate in the Program must be received in
good order at least five business days prior to the next rebalancing date. Once
a shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which AIM Funds
or what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, LOI, and
Automatic Investment Plan. Certain dealers/financial institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their dealers/financial institutions or AIM Distributors for more information.

    TERMS AND CONDITIONS OF EXCHANGES.  Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,

herein as the "Lower Load Funds," are sold at a public offering price that
includes a maximum sales charge of 1.00% of the public offering price of such
shares; and Class A shares or shares of certain other funds, listed below and
referred to herein as the "No Load Funds," are sold at net asset value, without
payment of a sales charge.

    An exchange is permitted only in the following circumstances: (a) if the
funds offer more than one class of shares, the exchange must be between the same
class of shares (e.g., Class A, Class B and Class C shares of a Multiple Class
Fund cannot be exchanged for each other) except that AIM Cash Reserve Shares of
AIM MONEY MARKET FUND may be exchanged for Class A shares of another Multiple
Class Fund; (b) the dollar amount of the exchange must be at least equal to the
minimum investment applicable to the shares of the fund acquired through such
exchange; (c) the shares of the fund acquired through exchange must be qualified
for sale in the state in which the shareholder resides; (d) the exchange must be
made between accounts having identical registrations and addresses; (e) the full
amount of the purchase price for the shares being exchanged must have already
been received by the fund; (f) the account from which shares have been exchanged
must be coded as having a certified taxpayer identification number on file or,
in the alternative, an appropriate IRS Form W-8 (certificate of foreign status)
or Form W-9 (certifying exempt status) must have been received by the fund; (g)
newly acquired shares (through either an initial or subsequent investment) are
held in an account for at least ten business days, and all other shares are held
in an account for at least one day, prior to the exchange; and (h) certificates
representing shares must be returned before shares can be exchanged. There is no
fee for exchanges among the AIM Funds.
    
 
    THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
 
                                      A-15
<PAGE>
                              AIM INVESTOR'S GUIDE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged
are redeemed at their net asset value as determined at NYSE Close on the day
that an exchange request in proper form (described below) is received. Exchange
requests received after NYSE Close will result in the redemption of shares at
their net asset value at NYSE Close on the next business day. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase, Exchange and
Redemption Orders (AIM MONEY MARKET FUND only)" for information regarding the
timing of exchange orders for AIM MONEY MARKET FUND. Normally, shares of an AIM
Fund to be acquired by exchange are purchased at their net asset value or
applicable offering price, as the case may be, determined on the date that such
request is received, but under unusual market conditions such purchases may be
delayed for up to five business days if it is determined that a fund would be
materially disadvantaged by an immediate transfer of the proceeds of the
exchange. If a shareholder is exchanging into a fund paying daily dividends
("Dividends, Distributions and Tax Matters -- Dividends and Distributions,"
below), and the release of the exchange proceeds is delayed for the foregoing
five-day period, such shareholder will not begin to accrue dividends until the
sixth business day after the exchange. Shares purchased by check may not be
exchanged until it is determined that the check has cleared, which may take up
to ten business days from the date that the check is received. See "Terms and
Conditions of Purchase of the AIM Funds -- Timing of Purchase Orders."
    
 
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
    EXCHANGES BY MAIL.  Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. If a shareholder does not wish to allow telephone
exchanges by any person in his account, he should decline that option on the
account application. AIM Distributors has made arrangements with certain dealers
and investment advisory firms to accept telephone instructions to exchange
shares between any of the AIM Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the funds, including the condition that any such dealer or
investment advisor enter into an agreement (which contains additional conditions
with respect to exchanges of shares) with AIM Distributors. To exchange shares
by telephone, a shareholder, dealer or investment advisor who has satisfied the
foregoing conditions must call AFS at (800) 959-4246. If a shareholder is unable
to reach AFS by telephone, he may also request exchanges by telegraph or use
overnight courier services to expedite exchanges by mail, which will be
effective on the business day received by the Transfer Agent as long as such
request is received prior to NYSE Close. The Transfer Agent and AIM Distributors
will not be liable for any loss, expense or cost arising out of any telephone
exchange request that they reasonably believe to be genuine, but may in certain
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's Social Security Number and current address, and mailings of
confirmations promptly after the transaction.
    
 
    EXCHANGES OF CLASS B AND CLASS C SHARES.  A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B or Class C
shares. For purposes of determining a shareholder's holding period of Class B or
Class C shares in the calculation of the applicable contingent deferred sales
 
                                      A-16

charge, the period of time during which Class B or Class C shares were held
prior to an exchange will be added to the holding period of the applicable Class
B or Class C shares acquired in an exchange.
    
 
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. Although
a contingent deferred sales charge may be applicable to certain redemptions as
described below, there is no redemption fee imposed when shares are redeemed or
repurchased; however, dealers may charge service fees for handling repurchase
transactions.
    
 
   
    MULTIPLE DISTRIBUTION SYSTEM.  CLASS B SHARES. Class B shares purchased
under the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attributable to Class B shares or (iii) on amounts that
represent capital appreciation in the shareholder's account above the purchase
price of the Class B shares.

    In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and other distributions; third, of shares
held for more than six years from the date such shares were purchased; and
fourth, of shares held less than six years from the date such shares were
purchased. The applicable sales charge will be applied against the lesser of the
current market value of shares redeemed or their original cost.
 
   
    Class B shares that are acquired during a tender offer by AIM Floating Rate
Fund ("Floating Rate Fund") pursuant to an exchange will be subject, in lieu of
the contingent deferred sales charge described above, to a contingent deferred
sales charge equivalent to the early withdrawal charge on the shares of the
Floating Rate Fund. For purposes of computing such early withdrawal charge, the
holding period of Class B shares being redeemed will include the holding period
of the Floating Rate Fund shares prior to exchange.
    
 
   
    CLASS C SHARES. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).

    WAIVERS. Contingent deferred sales charges on Class B and Class C shares
will be waived on redemptions (1) following the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code, of a shareholder or a
settlor of a living trust (provided AIM Distributors is notified of such death
or post-purchase disability at the time of the redemption request and is
provided with satisfactory evidence of such death or post-purchase disability),
(2) in connection with certain distributions from IRAs, custodial accounts
maintained pursuant to Code Section 403(b), deferred compensation plans
qualified under Code Section 457 and plans qualified under Code Section 401
(collectively, "Retirement Plans"), (3) pursuant to a Systematic Withdrawal
Plan, provided that amounts withdrawn under such plan do not exceed on an annual
basis 12% of the value of the shareholder's investment in Class B or Class C
shares at the time the shareholder elects to participate in the Systematic
Withdrawal Plan, (4) effected pursuant to the right of a Multiple Class Fund to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the designated minimum account size described
in the prospectus of such Multiple Class Fund, (5) effected by AIM of its
investment in Class B or Class C shares and (6) of Class C shares where such
investor's dealer of record, due to the nature of the investor's account,
notifies AIM Distributors prior to the time of investment that the dealer waives
the payment otherwise payable to the dealer described in the last paragraph
under the caption "Terms and Conditions of Purchase of the AIM Funds -- All
Groups of AIM Funds."
 
    Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
    Waiver category (2) above applies only to redemptions resulting from:
 
(i)  required minimum distributions to plan participants or beneficiaries who
    are age 70 1/2 or older, and only with respect to that portion of such
    distributions which does not exceed 12% annually of the participant's or
    beneficiary's account value in a particular AIM Fund;
 
(ii) in-kind transfers of assets where the participant or beneficiary notifies
    AIM Distributors of such transfer no later than the time such transfer
    occurs;
 
(iii) tax-free rollovers or transfers of assets to another Retirement Plan
    invested in Class B or Class C shares of one or more Multiple Class Funds;
 
(iv) tax-free returns of excess contributions or returns of excess deferral
    amounts; and
 
(v) distributions upon the death or disability (as defined in the Code) of the
    participant or beneficiary.
 
   
    Shareholders who purchased Class B shares of the AIM/GT Funds or Class C
shares of AIM GLOBAL TRENDS FUND prior to June 1, 1998 are entitled to certain
additional waivers of the contingent deferred sales charge on those shares as
described in the Statement of Additional Information of each respective fund
under "How to Purchase and Redeem Shares."
    
 
   
    CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES.  Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in the program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gains distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD, (i) shares of any
Load Fund or AIM Cash Reserve shares of AIM MONEY MARKET FUND [or Class A shares
of AIM DOLLAR FUND] which were acquired through an exchange of shares which
previously were subject to the 1% contingent deferred sales charge will be
credited with the period of time such exchanged shares were held, and (ii)
shares of any Load Fund which are subject to the 1% contingent deferred sales
charge and which were acquired through an exchange of shares of a Lower Load or
a No Load Fund which previously were not subject to the 1% contingent deferred
sales charge will not be credited with the period of time such exchanged shares
were held. The charge will be waived in the following circumstances: (l)
redemptions of shares by employee benefit plans ("Plans") qualified under
Sections 401 or 457 of the Code,

or Plans created under Section 403(b) of the Code and sponsored by nonprofit
organizations as defined under Section 501(c)(3) of the Code, where shares are
being redeemed in connection with employee terminations or withdrawals, and (a)
the total amount invested in a Plan is at least $1,000,000, (b) the sponsor of a
Plan signs a letter of intent to invest at least $1,000,000 in one or more of
the AIM Funds, or (c) the shares being redeemed were purchased by an
employer-sponsored Plan with at least 100 eligible employees; provided, however,
that Plans created under Section 403(b) of the Code which are sponsored by
public educational institutions shall qualify under (a), (b) or (c) above on the
basis of the value of each Plan participant's aggregate investment in the AIM
Funds, and not on the aggregate investment made by the Plan or on the number of
eligible employees; (2) redemptions of shares following the death or
post-purchase disability, as defined in Section 72(m)(7) of the Code, of a
shareholder or a settlor of a living trust; (3) redemptions of shares purchased
at net asset value by private foundations or endowment funds where the initial
amount invested was at least $1,000,000; (4) redemptions of shares purchased by
an investor in amounts of $1,000,000 or more where such investor's dealer of
record, due to the nature of the investor's account, notifies AIM Distributors
prior to the time of investment that the dealer waives the payments otherwise
payable to the dealer as described in the third paragraph under the caption
"Terms and Conditions of Purchase of the AIM Funds -- All Groups of AIM Funds;"
and (5) pursuant to a Systematic Withdrawal Plan, provided that amounts
withdrawn under such plan do not exceed on an annual basis 12% of the value of
the shareholder's investment in Class A shares at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.
 
    Shareholders who purchased $500,000 or more of Class A shares of the AIM/GT
Funds prior to June 1, 1998 are entitled to certain waivers of the contingent
deferred sales charge on those shares as described in the Statement of
Additional Information under "How to Purchase and Redeem Shares."
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
    In addition to these requirements, shareholders who have invested in a fund
to establish as IRA, should include the following information along with a
written request for either partial or full liquidation of fund shares; (a) a
statement as to whether or not the shareholder has attained age 59 1/2, and (b)
a statement as to whether or not the shareholder elects to have federal income
tax withheld from the proceeds of the liquidation.
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in this account, he should decline that option on the account
application. The telephone redemption feature can be used only if: (a) the
redemption proceeds are to be mailed to the address of record or transferred
electronically or wired to the pre-authorized bank account; (b) there has been
no change of address of record on the account within the preceding 30 days; (c)
the shares to be redeemed are not in certificate form; (d) the person requesting
the redemption can provide proper identification information, and (e) the
proceeds of the redemption do not exceed $50,000. Accounts in AIM Distributors'
prototype retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not
eligible for the telephone redemption option. AIM Distributors has made
arrangements with certain dealers and investment advisors to accept telephone
instructions for the redemption of shares. AIM Distributors reserves the right
to impose conditions on these dealers and investment advisors, including the
condition that they enter into agreements (which contain additional conditions
with respect to the redemption of shares) with AIM Distributors. The Transfer
Agent and AIM Distributors will not be liable for any loss, expense or cost
arising out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain

<PAGE>
                              AIM INVESTOR'S GUIDE
   
cases be liable for losses due to unauthorized or fraudulent transactions if
they do not follow reasonable procedures for verification of telephone
transactions. Such reasonable procedures may include recordings of telephone
transactions (maintained for six months), requests for confirmation of the
shareholder's taxpayer identification number and current address, and mailings
of confirmations promptly after the transaction.
    
 
    EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY).  If a redemption order
is received prior to 11:30 a.m. Eastern Time, the redemption will be effective
on that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
   
    REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and Class A shares of AIM DOLLAR FUND).  After completing
the appropriate authorization form, shareholders may use checks to effect
redemptions from AIM TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY
MARKET FUND and Class A shares of AIM DOLLAR FUND. This privilege does not apply
to retirement accounts or qualified plans. Checks may be drawn in any amount of
$250 or more. Checks drawn against insufficient shares in the account, against
shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented on the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent or certain financial institutions (or their designees) who
are authorized to accept redemption orders on behalf of the AIM Funds, provided
that such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer/financial institution to
ensure that all orders are transmitted on a timely basis. Any resulting loss
from the dealer/financial institution's failure to submit a request for
redemption within the prescribed time frame will be borne by that
dealer/financial institution. Telephone redemption requests must be made by NYSE
Close on any business day of an AIM Fund and will be confirmed at the price
determined as of the close of that day. No AIM Fund will accept requests which
specify a particular date for redemption or which specify any special
conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)

address that has been changed within the past 30 days; (5) requests to transfer
the registration of shares to another owner, (6) telephone exchange and
telephone redemption authorization forms; (7) changes in previously designated
wiring or electronic funds transfer instructions, and (8) written redemptions or
exchanges of shares previously reported as lost, whether or not the redemption
amount is under $50,000 or the proceeds are to be sent to the address of record.
These requirements may be waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
 
   
    REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY).  Within 90 days of a
redemption, a shareholder may invest all or part of the redemption proceeds in
Class A shares of any AIM Fund at the net asset value next computed after
receipt by the Transfer Agent of the funds to be reinvested; provided, however,
if the redemption was made from Class A shares of either AIM LIMITED MATURITY
TREASURY FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be
subject to the difference in sales charge between the shares redeemed and the
shares the proceeds are reinvested in. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of fund shares
on which a sales charge was paid are reinvested in shares of the same fund, or
exchanged for shares of another AIM Fund, at a reduced sales charge within 90
days of the payment of the sales charge, the shareholder's basis in the fund
shares redeemed may not include the amount of the sales charge paid, thereby
reducing the loss or increasing the gain recognized from the redemption;
however, the shareholder's basis in the fund shares purchased will include the
sales charge. Each AIM Fund may amend, suspend or cease offering the privilege
at any time as to shares redeemed after the date of such amendment, suspension
or cessation. This privilege may only be exercised once each year by a
shareholder with respect to each AIM Fund.
    
 
   
    Shareholders who are assessed a contingent deferred sales charge in
connection with the redemption of Class A shares and who subsequently reinvest a
portion or all of the value of the redeemed shares in Class A shares of any AIM
Fund within 90 days after such redemption may do so at net asset value if such
privilege is claimed at the time of reinvestment. Such reinvested proceeds will
not be subject to either a front-end sales charge at the time of reinvestment or
an additional contingent deferred sales charge upon subsequent redemption. In
order to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share (or share price) of each AIM Fund is
determined as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close
with respect to AIM MONEY MARKET FUND) on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
defining net asset value per share, futures and options contracts generally will
be valued 15 minutes after the close of trading of the NYSE. The net asset value
per share is calculated by subtracting a class' liabilities from its assets and
dividing the result by the total number of class shares outstanding. The
determination of net asset value per share is made in accordance with generally
accepted accounting principles. Among other items, liabilities include accrued
expenses and dividends payable, and total assets include portfolio securities
valued at their market value, as well as income accrued but

not yet received. Securities for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
supervision of the fund's officers and in accordance with methods which are
specifically authorized by its governing Board of Directors or Trustees.
Short-term obligations with maturities of 60 days or less, and the securities
held by the Money Market Funds, are valued at amortized cost as reflecting fair
value. AIM HIGH INCOME MUNICIPAL FUND, AIM MUNICIPAL BOARD FUND, AIM TAX-EXEMPT
BOND FUND OF CONNECTICUT and AIM TAX-FREE INTERMEDIATE FUND value variable rate
securities that have an unconditional demand or put feature exercisable within
seven days or less at par, which reflects the market value of such securities.
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each AIM Fund may make
additional distributions, if necessary, to avoid a non-deductible 4% federal
excise tax on certain undistributed income and capital gain (the "Excise Tax").
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in

like shares of another Multiple Class Fund, to the extent permitted. For funds
that do not declare a dividend daily, such dividends and distributions will be
reinvested at the net asset value per share determined on the ex-dividend date.
For funds that declare a dividend daily, such dividends and distributions will
be reinvested at the net asset value per share determined on the payable date.
Shareholders may elect, by written notice to the Transfer Agent, to receive such
distributions, or the dividend portion thereof, in cash, or to invest such
dividends and distributions in shares of another fund in the AIM Funds; provided
that (i) dividends and distributions attributable to Class B shares may only be
reinvested in Class B shares, (ii) dividends and distributions attributable to
Class C shares may only be reinvested in Class C shares, (iii) dividends and
distributions attributable to Class A shares may not be reinvested in Class B or
Class C shares, and (iv) dividends and distributions attributable to the AIM
Cash Reserve Shares of AIM MONEY MARKET FUND may not be reinvested in the Class
A shares of that Fund or in any Class B or Class C shares. Investors who have
not previously selected such a reinvestment option on the account application
form may contact the Transfer Agent at any time to obtain a form to authorize
such reinvestments in another AIM Fund. Such reinvestments into the AIM Funds
are not subject to sales charges, and shares so purchased are automatically
credited to the account of the shareholder.
    
 
    Dividends on Class B and Class C shares of an AIM Fund are expected to be
lower than dividends for Class A shares of that fund or AIM Cash Reserve Shares
because of higher distribution fees paid by Class B and Class C shares.
Dividends on all shares may also be affected by other class-specific expenses.
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
    
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS--GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares, except for "exempt-interest dividends" paid by AIM HIGH INCOME MUNICIPAL
FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM
TAX-EXEMPT CASH FUND and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt
Funds"), which are exempt from federal income tax. With respect to tax-exempt
shareholders, dividends and distributions from the AIM Funds are not subject to
federal income taxation to the extent permitted under the applicable tax
exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
 
                                      A-24
<PAGE>
                              AIM INVESTOR'S GUIDE
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM ADVISOR
INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE FUND, AIM ASIAN GROWTH FUND,
AIM DEVELOPING MARKETS FUND, AIM DOLLAR FUND, AIM EMERGING MARKETS FUND, AIM
EUROPEAN DEVELOPMENT FUND, AIM EUROPE GROWTH FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GOVERNMENT INCOME FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL HIGH
INCOME FUND, AIM GLOBAL INCOME FUND, AIM GLOBAL TRENDS FUND, AIM HIGH YIELD
FUND, AIM INCOME FUND, AIM INTERMEDIATE GOVERNMENT FUND, AIM INTERNATIONAL
EQUITY FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND, AIM LATIN
AMERICAN GROWTH FUND, AIM LIMITED MATURITY TREASURY FUND, AIM MONEY MARKET FUND,
AIM NEW PACIFIC GROWTH FUND, AIM STRATEGIC INCOME FUND or any of the Tax-Exempt
Funds will qualify for this dividends received deduction.
    
 
   
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year. No gain or loss will be recognized by shareholders upon
the automatic conversion of Class B shares of a Multiple Class Fund into Class A
shares of such fund.
    
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
   
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
    
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.
 
   
    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE
STATEMENTS OF ADDITIONAL INFORMATION. INVESTORS SHOULD CONSULT THEIR TAX
ADVISORS BEFORE INVESTING.
    
 
    TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION.  Shareholders will not be
required to include the "exempt-interest" portion of dividends paid by the
Tax-Exempt Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may affect the amount of social security and railroad retirement
benefits subject to federal income tax, may affect the deductibility of interest
on certain indebtedness of a shareholder, and may have other collateral federal
income tax consequences. In addition, the Tax-Exempt Funds may invest in
Municipal Securities the interest on which will constitute an item of tax
preference and which therefore could give rise to a federal alternative minimum
tax liability for certain shareholders; each Tax-Exempt Fund may invest up to
20% of its net assets in such securities and other
 
                                      A-25
<PAGE>
                              AIM INVESTOR'S GUIDE
taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
    The Tax-Exempt Funds may pay dividends to shareholders that are taxable, but
will endeavor to avoid investments that would result in taxable dividends. The
percentage of dividends that constitutes exempt-interest dividends, and the
percentage thereof (if any) that constitutes items of tax preference, will be
determined annually. These percentages may differ from the actual percentages
for any particular day.
 
   
    To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional fund shares.
Distributions of net capital gain will be taxable as long-term capital gains,
whether received in cash or additional fund shares and regardless of the length
of time a shareholder may have held his shares.
    
 
    From time to time, proposals have been introduced before Congress that would
have the effect of reducing or eliminating the federal tax exemption on
Municipal Securities. If such a proposal were enacted, the ability of the
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.

SPECIAL TAX INFORMATION.  For taxable years in which it is eligible to do so,
each of these funds may elect to pass through to its shareholders credits for
foreign taxes paid. If a fund makes such an election, a shareholder who receives
a distribution (1) will be required to include in gross income his proportionate
share of foreign taxes allocable to the distribution and (2) may claim a credit
or deduction for such share for his taxable year in which the distribution is
received, subject to the general limitations imposed on the allowance of foreign
tax credits and deductions. Shareholders should also note that certain gains or
losses attributable to fluctuations in exchange rates or foreign currency
forward contracts may increase or decrease the amount of income of the fund
available for distribution to shareholders and should note that if, for any
fund, such losses exceed other income during a taxable year, the fund would not
be able to pay ordinary income dividends for that year.

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
    
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be viewed to confirm Year 2000 compliance
upon installation.

                                 ADVISOR CLASS
    
                        PROSPECTUS -- SEPTEMBER 8, 1998
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Developing Markets Fund (the
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end, series, management investment
company. The Fund is a non-diversified portfolio which primarily seeks long-term
capital appreciation. Its secondary investment objective is income, to the
extent consistent with seeking capital appreciation. The Fund normally invests
substantially all of its assets in issuers in the developing (or "emerging")
markets of Asia, Europe, Latin America and elsewhere. A majority of the Fund's
assets ordinarily is invested in emerging market equity securities. The Fund
also invests in emerging market debt securities, which are selected based on
their potential to provide a combination of capital appreciation and current
income.
    
 
The Fund is designed for long-term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in equity and high yield, high
risk ("lower quality") debt securities that are predominantly speculative.
Investments of this type are subject to a greater risk of loss of principal and
interest. The Fund's investments in securities of issuers in developing markets
involves special considerations and risks that are not typically associated with
investments in securities of issuers in the United States or in other more
established markets. Investors should carefully assess the risks associated with
an investment in the Fund.
 
   
This Prospectus sets forth concisely the information about the Fund that
prospective investors should know before investing. It should be read and
retained for future reference. A Statement of Additional Information dated
September 8, 1998 has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated herein by reference. The Statement of Additional
Information is available without charge upon written request to the Trust at 11
Greenway Plaza, Suite 100, Houston, Texas 77046-1173 or by calling
1-800-347-4246. The SEC maintains a Web site at http://www.sec.gov that contains
the Statement of Additional Information, material incorporated by reference, and
other information regarding the Fund. Additional information about the Fund may
also be obtained from http://www.aimfunds.com.

                               holdings.

                               The Fund invests in foreign securities. Investments in foreign securities involve risks relating to
                               political and economic developments abroad and the differences between the regulations to which U.S.
                               and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings, and gains and losses realized on sales of securities. Securities of
                               foreign companies may be less liquid and their prices more volatile than those of securities of
                               comparable U.S. companies. The Fund normally invests substantially all of its assets in issuers in
                               emerging markets. Such investments entail greater risks than investing in issuers in developed
                               markets.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
 
                               The value of debt securities held by the Fund generally fluctuates inversely with interest rate
                               movements. Certain investment grade debt securities may possess speculative qualities. The Fund may
                               invest in below investment grade debt securities. Investments of this type are subject to a greater
                               risk of loss of principal and interest.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are estimated based on the fees and expenses the Fund is expected
    to incur during its initial year as an open-end fund and AIM's undertaking
    to limit the Fund's expenses (exclusive of brokerage commissions, taxes,
    interest and extraordinary expenses) to the annual rate of 1.50% of the
    average daily net assets of the Fund's Advisor Class shares. Without
    waivers, "Other expenses" and "Total Fund Operating Expenses" are estimated
    to be 0.65% and 1.63%, respectively, for Advisor Class shares. "Other
    expenses" include custody, transfer agent, legal and audit fees and other
    operating expenses. See "Management" herein and in the Statement of
    Additional Information for more information. Investors purchasing Advisor
    Class shares through financial planners, trust companies, bank trust
    departments or registered investment advisers, or under a "wrap fee"
    program, will be subject to additional fees charged by such entities or by
    the sponsors of such programs. Where any account advised by one of the
    companies affiliated with AMVESCAP PLC invests in Advisor Class shares of
    the Fund, such account shall not be subject to duplicative advisory fees.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the example of a 5% annual return are required by regulations of the SEC
    applicable to all mutual funds. The 5% annual return is not a prediction of
    and does not represent the Fund's projected or actual performance.

The table below provides condensed financial information concerning income and
capital changes for one share of G.T. Global Developing Markets Fund, Inc. (the
"Predecessor Fund") for the periods shown. This information is supplemented by
the financial statements and accompanying notes appearing in the Statement of
Additional Information. The Predecessor Fund was a closed-end investment company
whose single class of shares traded on the New York Stock Exchange ("NYSE"). On
October 31, 1997, the Fund, which had no previous operating history, acquired
the assets and assumed the liabilities of the Predecessor Fund. On that date,
all shareholders of the Predecessor Fund received Class A shares of the Fund.
The fees and expenses of the Fund will differ from those of the Predecessor
Fund. The Fund's fiscal year end will be October 31, rather than December 31,
which was the Predecessor Fund's fiscal year end.

PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's primary investment objective is long-term capital appreciation; its
secondary objective is income, to the extent consistent with seeking capital
appreciation. The Fund normally invests substantially all of its assets in
issuers in the developing (or "emerging") markets of Asia, Europe, Latin America
and elsewhere. A majority of the Fund's assets normally are invested in emerging
market equity securities. The Fund may invest in the following types of equity
securities: common stock, preferred stock, securities convertible into common
stock, American Depository Receipts, Global Depository Receipts, rights and
warrants to acquire such securities and substantially similar forms of equity
with comparable risk characteristics. The Fund may also invest in emerging
market debt securities that will be selected based on their potential to provide
a combination of capital appreciation and current income. There can be no
assurance the Fund will achieve its investment objective.
    
 
   
For purposes of the Fund's operations, emerging markets consist of all countries
determined by the Sub-adviser to have developing or emerging economies and
markets. These countries generally include every country in the world except the
United States, Canada, Japan, Australia, New Zealand and most countries located
in Western Europe. See "Investment Objectives and Policies" in the Statement of
Additional Information for a complete list of all the countries that the Fund
does not currently consider to be emerging markets.
    
 
   
For purposes of the Fund's policy of normally investing substantially all of its
assets in issuers in emerging markets, the Fund will consider investment in the
following emerging markets:

Greece            Paraguay       Zimbabwe
</TABLE>
    
 
   
Although the Fund considers each of the above-listed countries eligible for
investment, it will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements for the Fund's assets, overly
burdensome repatriation and similar restrictions, the lack of organized and
liquid securities markets, unacceptable political risks or for other reasons.
    
 
   
As used in this Prospectus, an issuer in an emerging market is an entity (1) for
which the principal securities trading market is an emerging market, as defined
above, (2) that (alone or on a consolidated basis) derives 50% or more of its
total revenues from business in emerging markets, provided that, in the
Sub-adviser's view, the value of such issuer's securities will tend to reflect
emerging market developments to a greater extent than developments elsewhere, or
(3) organized under the laws of, or with a principal office in, an emerging
market.
    
 
   
In selecting investments, the Sub-adviser seeks to identify those countries and
industries where economic and political factors, including currency movements,
are likely to produce above-average growth rates over the long term. The
Sub-adviser seeks those emerging markets that have strongly developing economies
and in which the markets are becoming more sophisticated. The Sub-adviser then
invests in those companies in such countries and industries that it believes are
best positioned and managed to take advantage of these economic and political
factors. The Sub-adviser believes that the issuers of securities in emerging
markets often have sales and earnings growth rates that exceed those in
developed countries and that such
    
 
                               Prospectus Page 7
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
growth rates may in turn be reflected in more rapid share price appreciation.
    
 
   
As opportunities to invest in securities in other emerging markets develop, the
Fund expects to expand and further broaden the group of emerging markets in
which it invests. In some cases, investments in debt securities could provide
the Fund with access to emerging markets in the early stages of their economic
development, when equity securities are not yet generally available or, in the
Sub-adviser's view, do not yet present an acceptable investment alternative.
While the Fund generally is not restricted in the portion of its assets that may
be invested in a single region, under normal conditions its assets will be
invested in issuers in at least four countries, and it will not invest more than
25% of its assets in issuers in one country. The Fund's holdings of any one
foreign currency together with securities denominated in or indexed to such
currency will not exceed 40% of its assets.
    
 
   
INVESTMENTS IN DEBT SECURITIES. The Fund may invest up to 50% of its total
assets in the following types of emerging market debt securities: (1) debt
securities issued or guaranteed by governments, their agencies,
instrumentalities or political subdivisions, or by government owned, controlled
or sponsored entities, including central banks (collectively, "Sovereign Debt"),
including Brady Bonds; (2) interests in issuers organized and operated for the
purpose of restructuring the investment characteristics of Sovereign Debt; (3)
debt securities issued by banks and other business entities; and (4) debt
securities denominated in or indexed to the currencies of emerging markets. Debt
securities held by the Fund may take the form of bonds, notes, bills,
debentures, bank debt obligations, short-term paper, loan participations,
assignments and interests issued by entities organized and operated for the
purpose of restructuring the investment characteristics of any of the foregoing.
There is no requirement with respect to the maturity or duration of debt
securities in which the Fund may invest.
    
 
   
There is no limitation on the percentage of the Fund's assets that may be
invested in debt securities that are rated below investment grade. Investment in
below investment grade debt securities involves a high degree of risk and can be
speculative. These debt securities are the equivalent of high yield, high risk
bonds, commonly known as "junk bonds." Debt securities in which the Fund will
invest may not be rated; if rated, it is expected that such ratings will be
below investment grade. See "Risk Factors -- Risks Associated with Debt
Securities" and "-- Risks Associated with Below Investment Grade Debt
Securities."
    
 
   
The Fund may invest in "Brady Bonds," which are debt restructurings that provide
for the exchange of cash and loans for newly issued bonds. Brady Bonds have been
issued by the countries of Albania, Argentina, Brazil, Bulgaria, Costa Rica,
Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria, Panama, Peru,
Philippines, Poland, Uruguay, Venezuela and Vietnam, and are expected to be
issued by other emerging market countries. As of the date of this Prospectus,
the Fund is not aware of the occurrence of any payment defaults on Brady Bonds.
Investors should recognize, however, that Brady Bonds do not have a long payment
history. In addition, Brady Bonds are often rated below investment grade.
    
 
   
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
    
 
   
Capital appreciation in debt securities may arise as a result of a favorable
change in relative foreign exchange rates, relative interest rate levels and/or
the creditworthiness of issuers.
    
 
   
ADDITIONAL INVESTMENT POLICIES
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy
for the Fund if it determines such a strategy to be warranted due to market,
economic or political conditions. Under a defensive strategy, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units such as
Euros) and/ or invest any portion or all of its assets in high quality money
market instruments of U.S. or foreign issuers. In addition, for temporary
defensive purposes, most or all of the Fund's investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund adopts a
temporary defensive posture, it will not be invested so as to directly achieve
its investment objectives.
    
 
                               Prospectus Page 8
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
In addition, pending investment of proceeds from new sales of Fund shares or in
order to meet ordinary daily cash needs, the Fund may hold cash (U.S. dollars,
foreign currencies or multinational currency units) and may invest in foreign or
domestic high quality money market instruments. For a description of money
market instruments, see "Temporary Defensive Strategies" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
   
BORROWING AND REVERSE REPURCHASE AGREEMENTS. In connection with meeting requests
for the redemption of Fund shares, the Fund may borrow from banks or may borrow
through reverse repurchase agreements. The Fund also may borrow up to 5% of its
total assets for temporary or emergency purposes other than to meet redemptions,
but total borrowings may not exceed 33 1/3% of its total assets. However, the
Fund will not purchase securities while borrowings in excess of 5% of its total
assets are outstanding. Any borrowing by the Fund may cause greater fluctuation
in the value of its shares than would be the case if it did not borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash and agrees to repurchase the security in the
future at an agreed-upon price that includes an interest component.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least 100% of the value of the
borrowed securities plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral if the borrower fails financially.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. To attempt to increase
return, the Fund may write call options on securities. This strategy will be
employed only when, in the opinion of the Sub-adviser, the size of the premium
the Fund receives for writing the option is adequate to compensate it against
the risk that appreciation in the underlying security may not be fully realized
if the option is exercised. The Fund also is authorized to write put options to
attempt to enhance return, although it does not currently intend to do so.
    
 
   
The Fund may also use forward currency contracts, futures contracts, options on
securities, options on currencies, options on indices and options on futures
contracts to attempt to hedge against the overall level of investment and
currency risk normally associated with its investments. These instruments are
often referred to as "derivatives," which may be defined as financial
instruments whose performance is derived, at least in part, from the performance
of another asset (such as a security, currency or an index of securities). The
Fund may enter into such instruments up to the full value of its portfolio
assets. See "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge its portfolio against movements in exchange rates.
    
 
   
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most emerging markets, to securities
denominated in such currencies or to securities of issuers domiciled or
principally engaged in business in such emerging markets. To the extent that
such a market does not exist, the Sub-adviser may not be able to effectively
hedge its investment in such markets.
    
 
   
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
    
 
                               Prospectus Page 9
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
stock indices to hedge against overall fluctuations in the securities markets or
in a specific market sector.
    
 
   
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or a specific market sector decline that could adversely affect the
Fund's portfolio. The Fund also may purchase index futures contracts and
purchase call options or write put options on such contracts to hedge against a
general market or market sector advance and thereby attempt to lessen the cost
of future securities acquisitions. Similarly, the Fund may use interest rate
futures contracts and options thereon to hedge the debt portion of its portfolio
against changes in the general level of interest rates.
    
 
   
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940, as amended
(the "1940 Act"), the Fund generally may invest up to 10% of its total assets in
the aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
    
 
   
Investment in other investment companies may involve the payment of substantial
premiums above the value of their portfolio securities and multiple layering of
fees and expenses and is subject to limitations under the 1940 Act and market
availability. The Fund does not intend to invest in other investment companies
unless, in the judgment of the Sub-adviser, the potential benefits of such
investment justify the payment of any applicable premium or sales charge. As a
shareholder in another investment company, the Fund would bear its ratable share
of that company's expenses, including its advisory and administration fees. At
the same time the Fund would continue to pay its own management fees and other
expenses. AIM and the Sub-adviser will waive their advisory fees to the extent
that the Fund invests in an Affiliated Fund.
    
 
   
PRIVATIZATIONS. The governments in some emerging markets have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain emerging markets, the ability of foreign entities such
as the Fund to participate in privatizations may be limited by local law or the
terms on which the Fund may be permitted to participate may be less advantageous
than those afforded local investors. There can be no assurance that governments
in emerging markets will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian bank and will mark to market daily such assets.
There is a risk that the securities may not be delivered and that the Fund may
incur a loss.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may invest in fixed and floating
rate loans ("Loans") arranged through private negotiations between a foreign
entity and one or more financial institutions ("Lenders"). The majority of the
Fund's investments in Loans in emerging markets is expected to be in the form of
participations in Loans ("Participations") and assignments of portions of Loans
from third parties ("Assignments"). Participations typically will result in the
    
 
                               Prospectus Page 10
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
Fund having a contractual relationship only with the Lender, not with the
borrower. The Fund will have the right to receive payments of principal,
interest and any fees to which it is entitled only from the Lender selling the
Participation and only upon receipt by the Lender of the payments from the
borrower. In connection with purchasing Participations, the Fund generally will
have no right to enforce compliance by the borrower with the terms of the loan
agreement relating to the loan, nor any rights of set-off against the borrower,
and the Fund may not directly benefit from any collateral supporting the Loan in
which it has purchased the Participation. As a result, the Fund will assume the
credit risk of both the borrower and the Lender that is selling the
Participation.
    
 
   
In the event of the insolvency of the Lender selling a Participation, the Fund
may be treated as a general creditor of the Lender and may not benefit from any
set-off between the Lender and the borrower. The Fund will acquire
Participations only if the Lender interpositioned between the Fund and the
borrower is determined by the Sub-adviser to be creditworthy. When the Fund
purchases Assignments from Lenders, the Fund will acquire direct rights against
the borrower on the Loan. However, because Assignments are arranged through
private negotiations between potential assignees and assignors, the rights and
obligations acquired by the Fund as the purchaser of an Assignment may differ
from, and be more limited than, those held by the assigning Lender.
    
 
   
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. The Fund also may invest in
zero coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt, and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
"interest" in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the interest on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
may be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
INDEXED COMMERCIAL PAPER. The Fund may invest without limitation in commercial
paper that is indexed to certain specific foreign currency exchange rates. The
terms of such commercial paper provide that its principal amount is adjusted
upwards or downwards (but not below zero) at maturity to reflect changes in the
exchange rate between two currencies while the obligation is outstanding. The
Fund will purchase such commercial paper with the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency, but the amount of principal payable by the issuer at
maturity will change in proportion to the change (if any) in the exchange rate
between the two specified currencies between the date the instrument is issued
and the date the instrument matures. While such commercial paper entails the
risk of loss of principal, the potential for realizing gains as a result of
changes in foreign currency exchange rates enables the Fund to hedge against a
decline in the U.S. dollar value of investments denominated in foreign
currencies while seeking to provide an attractive money market rate of return.
The Fund will not purchase such commercial paper for speculation.
    
 
   
OTHER INDEXED SECURITIES. The Fund may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of other
securities, securities indices, currencies, precious metals or other commodities
or other financial indicators. Indexed securities typically, but not always, are
debt securities or deposits whose value at maturity or coupon rate is determined
by reference to a specific instrument or statistic. The performance of indexed
securities depends to a great extent on the performance of the security,
currency or other instrument to which they are indexed and also may be
influenced by interest rate changes in the United States and abroad. At the same
time, indexed securities are subject to the credit risks associated with the
issuer of the security, and their values may decline substantially if the
    
 
                               Prospectus Page 11
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
issuer's creditworthiness deteriorates. Indexed securities may be more volatile
than the underlying instruments. New forms of indexed securities continue to be
developed. The Fund may invest in such securities to the extent consistent with
its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of its outstanding voting securities. A "majority of
its outstanding voting securities" means the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented, or (ii) more than 50% of the outstanding shares. In addition, the
Fund has adopted certain investment limitations that also may not be changed
without shareholder approval. A complete description of these limitations is
included in the Statement of Additional Information. Unless specifically noted,
the Fund's investment policies described in this Prospectus and in the Statement
of Additional Information may be changed by the Trust's Board of Trustees
without shareholder approval. The Fund's policies regarding lending, and the
percentage of Fund assets that may be committed to borrowing, are fundamental
policies and may not be changed without shareholder approval.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objectives. Investing in the Fund entails a substantial degree of risk, and an
investment in the Fund should be considered speculative. Investors are strongly
advised to consider carefully the special risks involved in investing in
emerging markets, which are in addition to the usual risks of investing in
developed markets around the world.
    
 
   
The Fund's net asset value will fluctuate, reflecting fluctuations in the market
value of its portfolio positions and its net currency exposure. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Fund will fluctuate
in response to general market and economic developments, as well as developments
affecting the particular issuers of such securities.
    
 
   
In addition, the value of debt securities held by the Fund generally will
fluctuate with the perceived creditworthiness of the issuers of such securities
and interest rates.
    
 
   
NON-DIVERSIFIED CLASSIFICATION. The Fund is classified under the 1940 Act as a
"non-diversified" fund. As a result, the Fund will be able to invest in a
smaller number of issuers than if it was classified under the 1940 Act as a
"diversified" fund. To the extent that the Fund invests in a smaller number of
issuers, the net asset value of its shares may fluctuate more widely and it may
be subject to greater investment and credit risk with respect to its portfolio.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of, the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to
    
 
                               Prospectus Page 12
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
domestic companies. In addition, certain costs attributable to foreign
investing, such as custody charges, are higher than those attributable to
domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's net investment income from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing that income.
    
 
   
Investing in some foreign countries involves risks relating to potential
political and economic instability within such countries and the risks of
expropriation, nationalization, confiscation of assets and property or the
imposition of restrictions on foreign investment and on repatriation of capital
invested. In the event of such expropriation, nationalization or other
confiscation, the Fund could lose its entire investment in that market.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, currency depreciation,
resource self-sufficiency and balance of payments positions. Investments in
foreign government securities involve special risks, including the risk that the
government issuers may be unable or unwilling to repay principal or interest
when due.
    
 
   
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between such currencies and the
U.S. dollar. Changes in currency exchange rates will affect the net asset value
of the Fund's shares and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by it.
    
 
   
INVESTING IN EMERGING MARKETS. Emerging markets generally are dependent heavily
upon international trade and, accordingly, have been and may continue to be
affected adversely by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. Inflation and rapid fluctuations in
inflation rates have had and may continue to have negative effects on the
economies and securities markets of certain countries with emerging markets.
    
 
   
Disclosure and regulatory standards in many respects are less stringent than in
the United States and other major markets. There also may be a lower level of
monitoring and regulation of emerging markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
    
 
   
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Fund to make intended securities purchases due to settlement
problems could cause it to miss attractive investment opportunities. Inability
to dispose of a portfolio security caused by settlement problems could result
either in losses to the Fund due to subsequent declines in value of the
portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.
    
 
   
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
developed countries. The risk also exists that an emergency situation may arise
in one or more emerging markets as a result of which trading of securities may
cease or may be substantially curtailed and prices for the Fund's portfolio
securities in such markets may not be readily available. Section 22(e) of the
1940 Act permits a registered investment company, such as the Fund, to suspend
redemption of its shares for any period during which an emergency exists, as
determined by the SEC. Accordingly, when the Fund believes that circumstances
dictate, it will promptly apply to the SEC for a determination that such an
emergency exists. During the period commencing with the Fund's identification of
such conditions until the date of any SEC action, the Fund's portfolio
securities in the affected markets will be valued at fair value determined in
good faith by or under the direction of the Trust's Board of Trustees.
    
 
   
RISKS ASSOCIATED WITH DEBT SECURITIES. The value of the debt securities held by
the Fund generally will vary inversely with market interest rates. If interest
rates in a market fall, the Fund's debt securities issued by governments or
companies in that market ordinarily will increase in value. If market interest
rates increase, however, the debt securities owned by the Fund in that market
will likely decrease in value.
    
 
                               Prospectus Page 13
<PAGE>
                          AIM DEVELOPING MARKETS FUND
 
   
RISKS ASSOCIATED WITH BELOW INVESTMENT GRADE DEBT SECURITIES. The Fund may
invest up to 50% of its total assets in debt securities rated below investment
grade. Such investments involve a high degree of risk.
    
 
   
Debt rated Baa by Moody's Investors Service, Inc. ("Moody's") is considered by
Moody's to have speculative characteristics. Debt rated BB, B, CCC, CC or C by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), and
debt rated Ba, B, Caa, Ca or C by Moody's is regarded, on balance, as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. While such
lower quality debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
conditions. Debt rated C by Moody's or S&P is the lowest rated debt that is not
in default as to principal or interest, and issues so rated can be regarded as
having extremely poor prospects of ever attaining any real investment standing.
Lower quality debt securities are also generally considered to be subject to
greater risk than securities with higher ratings with regard to a deterioration
of general economic conditions. These foreign debt securities are the equivalent
of high yield, high risk bonds, commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting it, such as its inability to meet specific
projected business forecasts or the unavailability of additional financing.
Similarly, certain emerging market governments that issue lower quality debt
securities are among the largest debtors to commercial banks, foreign
governments and supranational organizations such as the World Bank and may not
be able or willing to make principal and/or interest repayments as they come
due. The risk of loss due to default by the issuer is significantly greater for
the holders of lower quality securities because such securities are generally
unsecured and may be subordinated to the claims of other creditors of the
issuer.
    
 
   
Lower quality debt securities frequently have call or buy-back features that
would permit an issuer to call or repurchase the security from the Fund. In
addition, the Fund may have difficulty disposing of lower quality securities
because they may have a thin trading market. There may be no established retail
secondary market for many of these securities, and the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing its portfolio. The Fund may also acquire lower quality debt securities
during an initial underwriting or that are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include (1) potential adverse publicity, (2) heightened sensitivity to general
economic or political conditions and (3) the likely adverse impact of a major
economic recession.
    
 
   
The Fund may also incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in emerging markets can differ
from debt obligations issued by private entities in that remedies from defaults
generally must be pursued in the courts of the defaulting government, and legal
recourse is therefore somewhat
    
 
                               Prospectus Page 14
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
diminished. Political conditions, in terms of a government's willingness to meet
the terms of its debt obligations, also are of considerable significance. There
can be no assurance that the holders of commercial bank debt may not contest
payments to the holders of debt securities issued by governments in emerging
markets in the event of default by the governments under commercial bank loan
agreements.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities, and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.
    
 
   
CURRENCY RISK. Because the Fund may invest substantially in securities
denominated in currencies other than the U.S. dollar, and since the Fund may
hold foreign currencies, it will be affected favorably or unfavorably by
exchange control regulations or changes in the exchange rates between such
currencies and the U.S. dollar. Changes in currency exchange rates will affect
the net asset value of the Fund's shares and also may affect the value of
dividends and interest earned by the Fund and gains and losses realized by it.
Currencies generally are evaluated on the basis of fundamental economic criteria
(e.g., relative inflation and interest rate levels and trends, growth rate
forecasts, balance of payments status and economic policies) as well as
technical and political data. Exchange rates are determined by the forces of
supply and demand in the foreign exchange markets. These forces are affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. If the
currency in which a security is denominated appreciates against the U.S. dollar,
the dollar value of the security will increase. Conversely, a decline in the
exchange rate of the currency would adversely affect the value of the security
expressed in dollars.
    
 
   
Many of the currencies of emerging market countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries. Any devaluations in the currencies
in which the Fund's portfolio securities are denominated may have a detrimental
impact on the Fund.
    
 
   
Some countries also may have fixed currencies whose values against the U.S.
dollar are not independently determined. In addition, there is a risk that
certain countries may restrict the free conversion of their currencies into
other currencies. Further, certain currencies may not be internationally traded.
    
 
   
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. The Fund is authorized to
enter into options, futures and forward currency transactions. These
transactions involve certain risks, which include: (1) dependence on the
Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets and movements in
interest rates and currency markets; (2) imperfect correlation, or even no
correlation, between movements in the price of forward contracts, options,
futures contracts or options thereon and movements in the price of the currency
or security hedged or used for cover; (3) the fact that skills and techniques
needed to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Fund invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of the Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for the Fund to sell a security at a disadvantageous time, due to
the need for the Fund to maintain "cover" or to set aside securities in
connection with hedging transactions.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may have difficulty disposing of
Assignments and Participations. The liquidity of such securities is limited, and
the Fund anticipates that such securities could be sold only to a limited number
of institutional investors. The lack of a liquid secondary market could have an
adverse impact on the value of such securities and on the Fund's ability to
dispose of particular Assignments or Participations when necessary to meet its
liquidity needs or in response to a specific economic event, such as a
deterioration in the creditworthiness of the borrower. The lack of a liquid
secondary market for Assignments and Participations also may make it more
difficult for the Fund to assign a value to those securities for purposes of
valuing its portfolio and calculating its net asset value.
    
 
                               Prospectus Page 15
<PAGE>
                          AIM DEVELOPING MARKETS FUND
 
   
SOVEREIGN DEBT. The Fund may invest in sovereign debt securities of emerging
market governments, including Brady Bonds. Investments in such securities
involve special risks. The issuer of the debt or the governmental authorities
that control the repayment of the debt may be unable or unwilling to repay
principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn the Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
   
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
    
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's investments.
Emerging markets are faced with social and political issues, and some of them
have experienced high rates of inflation in recent years and have extensive
internal debt. Among other effects, high inflation and internal debt service
requirements may adversely affect the cost and availability of future domestic
sovereign borrowing to finance governmental programs and may have other adverse
social, political and economic consequences. Political changes or a
deterioration of a country's domestic economy or balance of trade may affect its
willingness to service its sovereign debt. Although the Sub-adviser intends to
manage the Fund in a manner that will minimize the exposure to such risks, there
can be no assurance that adverse political changes will not cause the Fund to
suffer a loss of interest or principal on any of its holdings.
    
 
   
In recent years, some of the emerging market countries in which the Fund expects
to invest have encountered difficulties in servicing their sovereign debt
obligations. Some of these countries have withheld payments of interest and/or
principal of sovereign debt. These difficulties have also led to agreements to
restructure external debt obligations -- in particular, commercial bank loans --
typically by rescheduling principal payments, reducing interest rates and
extending new credits to finance interest payments on existing debt. In the
future, holders of emerging market sovereign debt securities may be requested to
participate in similar rescheduling of such debt. Certain emerging market
countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by which a creditor may collect in whole or in
part sovereign debt on which an emerging market government has defaulted.
    
 
   
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
    
 
   
As noted above, sovereign debt obligations issued by emerging market governments
generally are deemed to be the equivalent in terms of quality to securities
rated below investment grade by Moody's and S&P. Such securities are regarded as
    
 
                               Prospectus Page 16
<PAGE>
                          AIM DEVELOPING MARKETS FUND
   
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligations and involve
major risk exposure to adverse conditions. Some of such securities, with respect
to which the issuer currently may not be paying interest or may be in payment
default, may be comparable to securities rated D by S&P or C by Moody's. The
Fund may have difficulty disposing of and valuing certain sovereign debt
obligations because there may be a limited trading market for such securities.
Because there is no liquid secondary market for many of these securities, the
Fund anticipates that such securities could be sold only to a limited number of
dealers or institutional investors.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day-to-day operations of the Fund are delegated to the officers
of the Trust, subject always to the investment objectives and policies of the
Fund and to the general supervision of the Trust's Board of Trustees. See "Board
of Trustees and Executive Officers" in the Statement of Additional Information
for information on the Trust's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include
determining the composition of the Fund's portfolio and placing orders to buy,
sell or hold particular securities; furnishing corporate officers and clerical
staff; providing office space, services and equipment; and supervising all
matters relating to the Fund's operation. For these services, the Fund pays AIM
investment management and administration fees, computed daily and paid monthly,
based on its average daily net assets, at the annualized rate of .975% on the
first $500 million, .95% on the next $500 million, .925% on the next $500
million and .90% on amounts thereafter. Out of the aggregate fees payable by the
Fund, AIM pays the Sub-adviser sub-advisory and sub-administration fees equal to
40% of the aggregate fees AIM receives from the Fund. The investment management
and administration fees paid by the Fund are higher than those paid by most
mutual funds. The Fund pays all expenses not assumed by AIM, the Sub-adviser,
AIM Distributors or other agents. AIM has undertaken to limit the Fund's
expenses (exclusive of brokerage commissions, taxes, interest and extraordinary
expenses) to the annual rate of 1.50% of the average daily net assets of the
Fund's Advisor Class shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with

asset management affiliates provided investment management and/or administrative
services to institutional, corporate and individual clients around the world
since 1969.

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser. High portfolio turnover (over
100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund will bear directly and could result in the
realization of net capital gains which would be taxable when distributed to
shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
Advisor Class shares of the Fund. Certain Trustees and officers of the Trust are
affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998 the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of thirteen separate and distinct series portfolios of
the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

trust department or registered investment adviser has investment discretion over
the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is
established under a "wrap fee" program and (ii) the account holder pays the
sponsor of such program an annual fee of at least .50% of the assets in the
account; (d) accounts advised by INVESCO (NY), Inc. or one of the companies

                                      A-2
<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in

<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

<PAGE>
                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                        PROSPECTUS -- SEPTEMBER 8, 1998
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Emerging Markets Fund (the
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end, series, management investment
company. The Fund is a diversified portfolio which seeks long-term growth of
capital by investing primarily in equity securities of companies in emerging
markets.
    
 
   
The Fund is designed for long term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in lower quality and unrated
foreign government bonds whose credit quality is generally considered the
equivalent of U.S. corporate debt securities commonly known as "junk bonds."
Investments of this type are subject to a greater risk of loss of principal and
interest. An investment in the Fund should be considered speculative and subject
to special risk factors, related primarily to the Fund's investments in emerging
markets. Purchasers should carefully assess the risks associated with an
investment in the Fund.
    
 
   
This Prospectus sets forth concisely the information about the Fund that
prospective investors should know before investing. It should be read and
retained for future reference. A Statement of Additional Information dated
September 8, 1998 has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated herein by reference. The Statement of Additional
Information is available without charge upon written request to the Trust at 11
Greenway Plaza, Suite 100, Houston, Texas 77046-1173 or by calling
1-800-347-4246. The SEC maintains a Web site at http://www.sec.gov that contains
the Statement of Additional Information, material incorporated by reference, and
other information regarding the Fund. Additional information about the Fund may
also be obtained from http:// www.aimfunds.com.

Investment Managers:           The Fund is managed by A I M Advisors, Inc. ("AIM") and is sub-advised and sub-administered by
                               INVESCO (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management
                               affiliates provide investment management and/or administrative services to institutional, corporate

                               subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its subsidiaries are an independent investment man-
                               agement group that has a significant presence in the institutional and retail segment of the
                               investment management industry in North America and Europe, and a growing presence in Asia. AIM was

                               Fund. The Class A and Class B shares have different distribution arrangements.
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               funds in The AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at net asset value
                               on any business day. See "How to Redeem Shares."
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset
                               values will fluctuate, reflecting fluctuations in the market value of its portfolio holdings.
                               The Fund will invest primarily in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
                               The Fund may invest up to 20% of its total assets in below investment grade debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect the current expense limits. "Other expenses" include custody,
    transfer agent, legal, audit and other operating expenses. AIM has
    undertaken to limit the Fund's expenses (exclusive of brokerage commissions,
    taxes, interest and extraordinary expenses) to the annual rate of 1.50% of
    the average daily net assets of the Fund's Advisor Class shares. Without
    reimbursements, "Other Expenses" and "Total Fund Operating Expenses" would
    have been 0.70% and 1.68%, respectively, for Advisor Class shares of the
    Fund. See "Management" herein and the Statement of Additional Information
    for more information. Investors purchasing Advisor Class shares through
    financial planners, trust companies, bank trust departments or registered
    investment advisers, or under a "wrap fee" program, will be subject to
    additional fees charged by such entities or by the sponsors of such
    programs. Where any account advised by one of the companies affiliated with
    AMVESCAP PLC invests in Advisor Class shares of the Fund, such account shall
    not be subject to duplicative advisory fees.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
    The table and the assumption in the Hypothetical Example of a 5% annual
    return are required by regulation of the SEC applicable to all mutual funds.
    The 5% annual return is not a prediction of and does not represent the
    Fund's projected or actual performance.

The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term growth of capital. Under normal
circumstances, the Fund seeks its objective by investing at least 65% of its
total assets in equity securities of companies in emerging markets. The Fund may
invest in the following types of equity securities: common stock, preferred
stock, securities convertible into common stock, rights and warrants to acquire
such securities and substantially similar forms of equity with comparable risk
characteristics. There can be no assurance that the Fund will meet its
investment objective.
    
 
   
For purposes of the Fund's operations, "emerging markets" consist of all
countries determined by the Sub-adviser to have developing or emerging economies
and markets. These countries generally include every country in the world except
the United States, Canada, Japan, Australia, New Zealand and most countries
located in Western Europe. See "Investment Objective and Policies" in the
Statement of Additional Information for a complete list of all the countries
that the Fund does not consider to be emerging markets.
    
 
   
For purposes of the Fund's policy of normally investing at least 65% of its
total assets in equity securities of issuers in emerging markets, the Fund will
consider investment in the following emerging markets:

Although the Fund considers each of the above-listed countries eligible for
investment, it will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements for the Fund's assets, overly
burdensome repatriation and similar restrictions, the lack of organized and
liquid securities markets, unacceptable political risks or for other reasons.
    
 
   
As used in this Prospectus, an issuer in an emerging market is an entity: (i)
for which the principal securities trading market is an emerging market, as
defined above; (ii) that (alone or on a consolidated basis) derives 50% or more
of its total revenues from business in emerging markets, provided that, in the
Sub-adviser's view, the value of such issuer's securities will tend to reflect
emerging market developments to a greater extent than developments elsewhere; or
(iii) organized under the laws of, or with a principal office in, an emerging
market.
    
 
   
The Fund may also invest up to 35% of its total assets in (i) debt securities of
government or corporate issuers in emerging markets; (ii) equity and debt
securities of issuers in developed countries, including the United States; (iii)
securities of issuers in emerging markets not included in the list of emerging
markets above, if investing therein becomes feasible and desirable subsequent to
the date of this Prospectus; and (iv) cash and money market instruments.
    
 
   
The Fund invests in those emerging markets that the Sub-adviser believes have
strongly developing economies and in which the markets are becoming more
sophisticated. In selecting investments, the Sub-adviser seeks to identify those
countries and industries where economic and political factors, including
currency movements, are likely to produce above-average growth rates. The
Sub-adviser then invests in those companies in such countries and industries
that are best positioned and managed to take advantage of these economic and
political factors. The Fund ordinarily will be invested in the securities of
issuers in at least three different emerging markets. In evaluating investments
in securities of issuers in developed markets, the Sub-
    
 
                               Prospectus Page 6
<PAGE>
                           AIM EMERGING MARKETS FUND
   
adviser will consider, among other things, the business activities of the issuer
in emerging markets and the impact that developments in emerging markets are
likely to have on the issuer.
    
 
   
The Sub-adviser believes that the issuers of securities in emerging markets
often have sales and earnings growth rates that exceed those in developed
countries and that such growth rates may in turn be reflected in more rapid
share price appreciation. Accordingly, the Sub-adviser believes that the Fund's
policy of investing in equity securities of companies in emerging markets may
enable the Fund to achieve results superior to those produced by mutual funds
with similar objectives that invest solely in equity securities of issuers
domiciled in the United States and/or in other developed markets.
    
 
   
INVESTMENTS IN DEBT SECURITIES. The Fund may invest in debt securities of
governmental and corporate issuers in emerging markets. Emerging market debt
securities often are rated below investment grade or not rated by U.S. rating
agencies. The Fund may invest up to 20% of its total assets in debt securities
rated below investment grade. Investment in below investment grade debt
securities involves a high degree of risk and can be speculative. These debt
securities are the equivalent of high yield, high risk bonds, commonly known as
"junk bonds." See "Risk Factors -- Risks Associated with Debt Securities."
    
 
   
If the rating of a debt security held by the Fund drops below a minimum rating
considered acceptable by the Sub-adviser, the Fund will dispose of any such
security as soon as practicable and consistent with the best interests of the
Fund and its shareholders.
    
 
   
Growth of capital in debt securities may arise as a result of favorable changes
in relative foreign exchange rates, in relative interest rate levels and/ or in
the creditworthiness of issuers. The receipt of income from debt securities
owned by the Fund is
incidental to its objective of long-term growth of capital.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic, or
political conditions. Under a defensive strategy, the Fund temporarily may
invest up to 100% of its assets in cash (U.S. dollars, foreign currencies,
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of its investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund employs a
temporary defensive strategy, it will not be invested so as to achieve directly
its investment objective. In addition, pending investment of proceeds from new
sales of Fund shares or to meet ordinary daily cash needs, the Fund temporarily
may hold cash (U.S. dollars, foreign currencies or multinational currency units)
and may invest any portion of its assets in money market instruments. For a
description of money market instruments in which the Fund may invest, see
"Temporary Defensive Strategies" in the "Investment Objectives and Policies"
section of the Statement of Additional Information.
    
 
   
ADDITIONAL INVESTMENT POLICIES
    
 
   
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940 (the "1940
Act"), the Fund generally may invest up to 10% of its total assets in the
aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
    
 
   
Investment in other investment companies may involve the payment of substantial
premiums above the value of such investment companies' portfolio securities and
is subject to limitations under the 1940 Act and market availability. The Fund
does not intend to invest in such investment companies unless, in the judgment
of the Sub-adviser, the potential benefits of such investment justify the
payment of any applicable premium or sales charge. As a shareholder in an
investment company, the Fund would bear its ratable share of that investment
company's expenses, including its advisory and administration fees. At the same
time the Fund would continue to pay its own management fees and other expenses.
AIM and the Sub-adviser will waive their advisory fees to the extent that the
Fund invests in an Affiliated Fund.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other
    
 
                               Prospectus Page 7
<PAGE>
                           AIM EMERGING MARKETS FUND
   
institutional investors. Securities lending allows a Fund to retain ownership of
the securities loaned and, at the same time, enhances the Fund's total return.
At all times a loan is outstanding, the Fund's borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to the value of the borrowed
securities plus any accrued interest or such other collateral as permitted by
the Fund's investment program and regulatory agencies, and as approved by the
Board. The Fund limits its loans of portfolio securities to an aggregate of 30%
of the value of its total assets, measured at the time any such loan is made.
The risks in lending portfolio securities, as with other extensions of secured
credit, consist of possible delays in receiving additional collateral or in
recovery of the loaned securities and possible loss of rights in the collateral
should the borrower fail financially.
    
 
   
PRIVATIZATIONS. The governments in some emerging markets have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain emerging markets, the ability of foreign entities such
as the Fund to participate in privatizations may be limited by local law, or the
terms on which the Fund may be permitted to participate may be less advantageous
than those afforded local investors. There can be no assurance that governments
in emerging markets will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
BORROWING. It is a fundamental policy of the Fund that it may borrow an amount
up to 33 1/3% of its total assets in order to meet redemption requests.
Borrowing may cause greater fluctuation in the value of the Fund's shares than
would be the case if the Fund did not borrow, but also may enable the Fund to
retain favorable securities positions rather than liquidating such positions to
meet redemptions. It is a nonfundamental policy of the Fund that the Fund will
not purchase securities during times when outstanding borrowings represent 5% or
more of the Fund's total assets.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian bank and will mark to market daily such assets.
There is a risk that the securities may not be delivered and that the Fund may
incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment risk normally associated with the
portfolio. These instruments are often referred to as "derivatives," which may
be defined as financial instruments whose performance is derived, at least in
part, from the performance of another asset (such as a security, currency or an
index of securities). The Fund may enter into such instruments up to the full
value of its portfolio assets. See "Risk Factors -- Options, Futures and Foreign
Currency Transactions" herein and "Options, Futures and Currency Strategies" in
the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and
    
 
                               Prospectus Page 8
<PAGE>
                           AIM EMERGING MARKETS FUND
   
options on such futures contracts to hedge against movements in exchange rates.
    
 
   
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most emerging markets, to securities
denominated in such currencies or to securities of issuers domiciled or
principally engaged in business in such emerging markets. To the extent that
such a market does not exist, the Sub-adviser may not be able to effectively
hedge its investment in such markets.
    
 
   
The Fund may purchase and sell put and call options on securities to hedge
against the risk of fluctuations in the prices of securities held by the Fund or
that the Sub-adviser intends to include in the Fund's portfolio. The Fund also
may purchase and sell put and call options on indices to hedge against overall
fluctuations in the securities markets generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
adversely affect the Fund's portfolio. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolios against changes in the general level of interest
rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations as
fundamental policies which also may not be changed without shareholder approval.
A complete description of these limitations is included in the Statement of
Additional Information. Unless specifically noted, the Fund's investment
policies described in this Prospectus and in the Statement of Additional
Information may be changed by the Trust's Board of Trustees without shareholder
approval. If a percentage restriction on investment or utilization of assets in
an investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. Investing in the Fund entails a substantial degree of risk and an
investment in the Fund should be considered speculative. Investors are strongly
advised to consider carefully the special risks involved in emerging markets,
which are in addition to the usual risks of investing in developed markets
around the world.
    
 
   
The Fund's net asset value will fluctuate, reflecting fluctuations in the market
value of its portfolio positions and its net currency exposure. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Fund will fluctuate
in response to general market and economic developments, as well as developments
affecting the particular issuers of such securities.
    
 
   
Investing in emerging markets involves risks relating to potential political and
economic instability
    
 
                               Prospectus Page 9
<PAGE>
                           AIM EMERGING MARKETS FUND
   
within such markets and the risks of expropriation, nationalization,
confiscation of assets and property or the imposition of restrictions on foreign
investment and on repatriation of capital invested. In the event of such
expropriation, nationalization or other confiscation, the Fund could lose its
entire investment in that market.
    
 
   
Economies in individual emerging markets may differ favorably or unfavorably
from the U.S. economy in such respects as growth of gross domestic product,
rates of inflation, currency depreciation, capital reinvestment, resource self-
sufficiency and balance of payments positions. Many emerging market countries
have experienced high rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain countries with
emerging markets.
    
 
   
Emerging markets generally are dependent heavily upon international trade and,
accordingly, have been and may continue to be affected adversely by trade
barriers, exchange controls, managed adjustments in relative currency values and
other protectionist measures imposed or negotiated by the countries with which
they trade.
    
 
   
Disclosure and regulatory standards in many respects are less stringent than in
the U.S. and other major markets. There also may be a lower level of monitoring
and regulation of emerging markets and the activities of investors in such
markets, and enforcement of existing regulations has been extremely limited. In
addition, the securities of non-U.S. issuers generally are not registered with
the SEC, nor are the issuers thereof usually subject to the SEC's reporting
requirements. Accordingly, there may be less publicly available information
about foreign securities and issuers than is available with respect to U.S.
securities and issuers. Foreign companies generally are not subject to uniform
accounting, auditing and financial reporting standards, practices and
requirements comparable to those applicable to U.S. companies. The Fund's net
investment income and/or capital gains from its foreign investment activities
may be subject to non-U.S. withholding taxes.
    
 
   
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Fund to make intended securities purchases due to settlement
problems could cause the Fund to miss attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems could
result either in losses to the Fund due to subsequent declines in value of the
portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.
    
 
   
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
developed countries. The risk also exists that an emergency situation may arise
in one or more emerging markets as a result of which trading of securities may
cease or may be substantially curtailed and prices for the Fund's portfolio
securities in such markets may not be readily available. Section 22(e) of the
1940 Act permits a registered investment company, such as the Fund, to suspend
redemption of its shares for any period during which an emergency exists, as
determined by the SEC. Accordingly, when the Fund believes that circumstances
dictate, it will promptly apply to the SEC for a determination that such an
emergency exists within the meaning of Section 22(e) of the 1940 Act. During the
period commencing from the Fund's identification of such conditions until the
date of any SEC action, the Fund's portfolio securities in the affected markets
will be valued at fair value determined in good faith by or under the direction
of the Trust's Board of Trustees.
    
 
   
RISKS ASSOCIATED WITH DEBT SECURITIES. The value of the debt securities held by
the Fund generally will vary inversely with market interest rates. If interest
rates in a market fall, the Fund's debt securities issued by governments or
companies in that market ordinarily will increase in value. If market interest
rates increase, however, the debt securities owned by the Fund in that market
will likely decrease in value.
    
 
   
The Fund may invest up to 20% of its total assets in debt securities rated below
investment grade. Such investments involve a high degree of risk.
    
 
   
Debt rated Baa by Moody's Investors Service, Inc. ("Moody's") is considered by
Moody's to have speculative characteristics. Debt rated BB, B, CCC, CC or C by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), and
debt rated Ba, B, Caa, Ca or C by Moody's is
    
 
                               Prospectus Page 10
<PAGE>
                           AIM EMERGING MARKETS FUND
   
regarded, on balance, as predominantly speculative with respect to the issuer's
capacity to pay interest and repay principal in accordance with the terms of the
obligation. While such lower quality debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions. Debt rated C by Moody's or S&P is the
lowest rated debt that is not in default as to principal or interest and such
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing. Lower quality debt securities are also
generally considered to be subject to greater risk than securities with higher
ratings with regard to a deterioration of general economic conditions. These
foreign debt securities are the equivalent of high yield, high risk bonds,
commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. Similarly, certain emerging market governments that issue lower
quality debt securities are among the largest debtors to commercial banks,
foreign governments and supranational organizations such as the World Bank, and
may not be able or willing to make principal and/or interest repayments as they
come due. The risk of loss due to default by the issuer is significantly greater
for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities frequently have call or buy-back features which
would permit an issuer to call or repurchase the security from the Fund. In
addition, the Fund may have difficulty disposing of lower quality securities
because they may have a thin trading market. There may be no established retail
secondary market for many of these securities, and the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing the Fund's portfolio. The Fund may also acquire lower quality debt
securities during an initial underwriting or which are sold without registration
under applicable securities laws. Such securities involve special considerations
and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession.
    
 
   
The Fund may also incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in emerging markets can differ
from debt obligations issued by private entities in that remedies from defaults
generally must be pursued in the courts of the defaulting government, and legal
recourse is therefore somewhat diminished. Political conditions, in terms of a
government's willingness to meet the terms of its debt obligations, also are of
considerable significance. There can be no assurance that the holders of
commercial bank debt may not contest payments to the holders of debt securities
issued by governments in emerging markets in the event of default by the
governments under commercial bank loan agreements.

                           AIM EMERGING MARKETS FUND
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "Illiquid
Securities."
    
 
   
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
    
 
   
CURRENCY RISK. Because the Fund may invest substantially in securities
denominated in currencies other than the U.S. dollar, and since the Fund may
hold foreign currencies, the Fund will be affected favorably or unfavorably by
exchange control regulations or changes in the exchange rates between such
currencies and the U.S. dollar. Changes in currency exchange rates will
influence the value of the Fund's shares, and also may affect the value of
dividends and interest earned by the Fund and gains and losses realized by the
Fund. Currencies generally are evaluated on the basis of fundamental economic
criteria (e.g., relative inflation and interest rate levels and trends, growth
rate forecasts, balance of payments status and economic policies) as well as
technical and political data. Exchange rates are determined by the forces of
supply and demand in the foreign exchange markets. These forces are affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. If the
currency in which a security is denominated appreciates against the U.S. dollar,
the dollar value of the security will increase. Conversely, a decline in the
exchange rate of the currency would adversely affect the value of the security
expressed in dollars.
    
 
   
Many of the currencies of emerging market countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries. Any devaluations in the currencies
in which the Fund's portfolio securities are denominated may have a detrimental
impact on the Fund.
    
 
   
Some countries also may have fixed currencies whose values against the U.S.
dollar are not independently determined. In addition, there is a risk that
certain countries may restrict the free conversion of their currencies into
other currencies. Further, certain currencies may not be internationally traded.
    
 
   
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets and movements in
interest rates and currency markets; (2) imperfect correlation, or even no
correlation, between movements in the price of forward contracts, options,
futures contracts or options thereon and movements in the price of the currency
or security hedged or used for cover; (3) the fact that skills and techniques
needed to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Fund invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of the Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for the Fund to sell a security at a disadvantageous time, due to
the need for the Fund to maintain "cover" or to set aside securities in
connection with hedging transactions.

The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with

AIM, the investment sub-advisory and sub-administration agreement between AIM
and the Sub-adviser, the agreements with AIM Distributors regarding distribution
of the Fund's shares, the custody agreement and the transfer agency agreement.
The day to day operations of the Fund are delegated to the officers of the
Trust, subject always to the objective and policies of the Fund and to the
general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's Board of Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment manager and administrator include, but are
not limited to, determining the composition of the Fund's portfolio and placing
orders to buy, sell or hold particular securities; furnishing corporate officers
and clerical staff; providing office space, services and equipment; and
supervising all matters relating to the Fund's operation. For these services,
the Fund pays AIM investment management and administration fees, computed daily
and paid monthly, based on its average daily net assets, at the annualized rate
of .975% on the first $500 million, .95% on the next $500 million, .925% on the
next $500 million, and .90% on amounts thereafter. Out of the aggregate fees
payable by the Fund, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit each Fund's expenses (exclusive of brokerage commissions,
taxes, interest and extraordinary expenses) to the annual rate of 1.50% the
average daily net assets of the Fund's Advisor Class shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly-owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser. High portfolio turnover (over
100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund will bear directly and could result in the
realization of net capital gains which would be taxable when distributed to
shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provide AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which
    
 
                               Prospectus Page 14
<PAGE>
                           AIM EMERGING MARKETS FUND
   
means that the holders of a majority of the shares voting for the election of
Trustees can elect all the Trustees. A Trustee may be removed at any meeting of
the shareholders of the Trust by a vote of the shareholders owning at least
two-thirds of the outstanding shares. Any Trustee may call a special meeting of
shareholders for any purpose. Furthermore, Trustees shall promptly call a
meeting of shareholders solely for the purpose of removing one or more Trustees
when requested in writing to do so by shareholders holding 10% of the Trust's
outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the fund with other shares of the Fund and is
entitled to such other shares of the Fund and is entitled to such dividends and
distributions out of the income earned and gain realized on the assets belonging
to the Fund as may be declared by the Board of Trustees. Each share of the Fund
is equal in earnings, assets and voting privileges except that each class
normally has exclusive voting rights with respect to its distribution plan and
bears the expenses, if any, related to the distribution of its shares. Shares of
the Fund, when issued, are fully paid and nonassessable.

                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in
    
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                               herein. See "Exchange Privilege."
 
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at net asset value
                               on any business day. See "How to Redeem Shares."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve its investment objective. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the Portfolio's
                               portfolio holdings. The Portfolio's policy of concentrating its investments in companies in the
                               consumer products and services industries may cause the Fund's net asset value to fluctuate more than
                               if it invested in a greater number of industries.
 
                               The Portfolio may invest in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.

- --------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 1.50% of the average daily net assets of the Fund's Advisor
    Class shares. "Other expenses" include custody, transfer agency, legal,
    audit and other operating expenses. See "Management" herein and the
    Statement of Additional Information for more information. Investors
    purchasing Advisor Class shares through financial planners, trust companies,
    bank trust departments or registered investment advisers, or under a "wrap
    fee" program, will be subject to additional fees charged by such entities or
    by the sponsors of such programs. Where any account advised by one of the
    companies composing or affiliated with AMVESCAP PLC invests in Advisor Class
    shares of the Fund, such account shall not be subject to duplicative
    advisory fees.
    
 
   
    The Board of Trustees of the Trust believes that the aggregate per share
    expenses of the Fund and its Portfolio will be approximately equal to the
    expenses the Fund would incur if its assets were invested directly in the
    type of securities being held by its Portfolio.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds. The 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.

- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
 
   
                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that manufacture, market, retail or distribute consumer products and services.
The Portfolio's investment objective is identical to that of the Fund. There can
be no assurance that the Fund or Portfolio will achieve its investment
objective.
    
 
   
At least 65% of the Portfolio's total assets normally will be invested in common
and preferred stocks and warrants to acquire such securities issued by consumer
products and services companies. A "consumer products or services" company is an
entity in which (i) at least 50% of either the revenues or earnings was derived
from activities relating to consumer products or services, or (ii) at least 50%
of the assets was devoted to such activities, based on the company's most recent
fiscal year. The remainder of the Portfolio's assets may be invested in debt
securities issued by consumer products or services companies and/or equity and
debt securities of companies outside the consumer products or services
industries, which, in the opinion of the Sub-adviser, stand to benefit from
developments in such industries.
    
 
   
GLOBAL CONSUMER PRODUCTS AND SERVICES INDUSTRIES INVESTMENT. Examples of
consumer products and services companies include those that manufacture, market,
retail, or distribute: durable goods (such as homes, household goods,
automobiles, boats, furniture and appliances, and computers); non-durable goods
(such as food and beverages and apparel); media, entertainment, broadcasting,
publishing and sports-related goods and services (such as television and radio
broadcast, motion pictures, wireless communications, gaming casinos, theme
parks, restaurants and lodging); and goods and services to companies in the
foregoing industries (such as advertisers, textile companies and distribution
and shipping companies).
    
 
   
The Portfolio expects that a significant portion of its assets may be invested
in the securities of U.S. issuers from time to time, particularly those that
market their products globally. However, consumer products and services
companies of a particular nation or region of the world are often operated and
owned in their local markets, close to their customers. These companies, the
Sub-adviser believes, may offer superior opportunities for capital growth as
compared to their larger, multinational counterparts. Certain global markets may
be more attractive than others from time to time; companies dependent on U.S.
markets, for example, may be outperformed by companies not dependent on U.S.
markets.
    
 
   
The Sub-adviser also believes that the demand for consumer products and services
worldwide will increase along with rising disposable incomes in both developed
and developing nations. Emerging economies, such as those in China, Southeast
Asia, Eastern Europe and Latin America, offer opportunities for the growth and
expansion of consumer markets. These regions currently comprise a growing source
of inexpensive consumer products for export and a growing source of demand for
consumer products and services as the disposable incomes of their populations
increase. In the Sub-adviser's view, these changes are likely to create
investment opportunities in companies, both local and multinational, that are
able to employ innovative manufacturing, marketing, retailing and distribution
methods to open new markets and/or expand existing markets.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the
consumer products and services industries are headquartered outside of the
United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets located throughout the world and the substantial global
resources of AMVESCAP PLC in attempting to identify those countries and
companies then providing the greatest potential for long-term
    
 
                               Prospectus Page 6
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
capital appreciation. In this fashion, the Sub-adviser seeks to enable
shareholders to capitalize on the substantial investment opportunities and the
potential for long-term growth of capital presented by the global consumer
products and services industries represented in the Portfolio.
    
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 50% of the Portfolio's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank
    
 
                               Prospectus Page 7
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
or broker/dealer, in return for cash, and agrees to repurchase the security in
the future at an agreed upon price which includes an interest component. A
"roll" borrowing transaction involves the Portfolio's sale of securities
together with its commitment (for which the Portfolio may receive a fee) to
purchase similar, but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolios to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other collateral as permitted by the Portfolio's investment program and
regulatory agencies, and as approved by the Board. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Portfolio's holdings. The Portfolio also may

                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
purchase stock index futures contracts and purchase call options or write put
options on such contracts to hedge against a general stock market or market
sector advance and thereby attempt to lessen the cost of future securities
acquisitions. The Portfolio may use interest rate futures contracts and options
thereon to hedge the debt portion of its portfolio against changes in the
general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of that Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval. The investment policies of the Fund are identical to the
investment policies of the Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in its corresponding
Portfolio's investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts," respectively, in the
Investment Objectives and Policies section of the Statement of Additional
Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because a Fund will invest only in its corresponding Portfolio, the Fund's
shareholders will acquire only an indirect interest in the investments of that
Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in a Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may experience different
returns than investors in another investment company that invests exclusively in
the
    
 
                               Prospectus Page 9
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
Portfolio. As of the date of this Prospectus, the Fund is the only institutional
investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the consumer products and
services industries, an investment in it may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
Moreover, the value of the shares of the Fund will be especially susceptible to
factors affecting the consumer products and services industries. Accordingly,
the Fund should not be considered a complete investment program.
    
 
   
CONSUMER PRODUCTS AND SERVICES INDUSTRIES. The performance of consumer products
and services companies, relates closely to the actual or perceived performance
of the overall economy, interest rates and consumer confidence. In addition,
changes in demographics and consumer tastes may also affect the demand for, and
success of, particular consumer products and services. Many consumer products
and services companies have unpredictable earnings, due in part to changes in
consumer tastes and intense competition. As a result, such companies may be
subject to increased share price volatility. The consumer products and services
industries may also be subject to greater government regulation, including trade
regulation, than many other industries. Changes in governmental policy and the
need for regulatory approvals may have a material effect on the products and
services offered by companies in the consumer products and services industries.
Such governmental regulations may also hamper the development of new business
opportunities.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Portfolio's interest and dividends from foreign issuers may be
subject to non-U.S. withholding taxes, thereby reducing the Portfolio's net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could
    
 
                               Prospectus Page 10
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
affect the Portfolio's investments in those countries. Moreover, individual
foreign economies may differ favorably or unfavorably from the U.S. economy in
such respects as growth of gross national product, rate of inflation, rate of
savings and capital reinvestment, resource self-sufficiency and balance of
payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 20%, of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be
    
 
                               Prospectus Page 11
<PAGE>
                 AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND
   
subordinated to the claims of other creditors of the issuer.
    
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if it did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
   
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the Portfolio to sell a security at a disadvantageous time, due to the need for
the Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.

- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the investment objective and policies of the Fund
and the Portfolio and to the general supervision of the Boards. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers and administrators to the Fund and the
Portfolio include, but are not limited to, determining the composition of the
investment holdings of the Portfolio and placing orders to buy, sell or hold
particular securities. In addition, AIM and the Sub-adviser provide the
following administration services to the Portfolio and the Fund: furnishing
corporate officers and clerical staff; providing office space, services and
equipment; and supervising all matters relating to the Portfolio's and the
Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by its corresponding
Portfolio to AIM and the Sub-adviser. The Portfolio pays AIM a fee, based on the
Portfolio's average daily net assets at the annualized rate of .725% on the
first $500 million, .70% on the next $500 million, .675% on the next $500
million and .65% on all amounts thereafter. Out of its aggregate fees payable by
the Fund and the Portfolio, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund and the Portfolio. The investment management and administration fees paid
by the Fund and the Portfolio are higher than those paid by most mutual funds.
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 1.50% of the average daily net assets of the Fund's Advisor Class
shares.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP

PLC acquired LGT's Asset Management Division, which included the Sub-adviser and
certain other affiliates. As a result of this transaction, the Sub-adviser is
now an indirect wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the
Sub-adviser and its worldwide asset management affiliates provided investment
management and/or administrative services to institutional, corporate and
individual clients around the world since 1969.
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
Advisor Class shares of the Fund. Certain Trustees and officers of the Trust are
affiliated with AIM Distributors.
    
 
   
The Distribution Agreements provide AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may continue to establish other
funds, each corresponding to a distinct investment portfolio and a distinct
series of the Trust's shares of beneficial interest. Shares of each fund are
entitled to one vote per share (with proportional voting for fractional shares)
and are freely transferable. Shareholders have no preemptive rights. Other
    
 
                               Prospectus Page 14

than the automatic conversion of Class B shares to Class A shares, there are no
conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other shares do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as

other fiduciaries purchasing shares for employee benefit plans that are
sponsored by organizations that have at least 1,000 employees; (b) any account
with assets of at least $10,000 if (i) a financial planner, trust company, bank
trust department or registered investment adviser has investment discretion over
the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is
established under a "wrap fee" program and (ii) the account holder pays the
sponsor of such program an annual fee of at least .50% of the assets in the
account; (d) accounts advised by INVESCO (NY), Inc. or one of the companies

    Financial planners, trust companies, bank trust departments and registered

                                      A-2
<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in
    
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6

                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7

                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.

DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

<S>                            <C>
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve
                               its investment objective. The Fund's net asset value will
                               fluctuate, reflecting fluctuations in the market value of the
                               Portfolio's portfolio holdings. The Portfolio's policy of
                               concentrating its investments in companies in the financial
                               services industries may cause the Fund's net asset value to
                               fluctuate more than if it invested in a greater number of
                               industries.
                               The Portfolio may invest in foreign securities. Investments in
                               foreign securities involve risks relating to political and
                               economic developments abroad and the differences between the
                               regulations to which U.S. and foreign issuers are subject.
                               Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency
                               exchange rates will affect the Fund's net asset value, earnings
                               and gains and losses realized on sales of securities. Securities
                               of foreign companies may be less liquid and their prices more
                               volatile than those of securities of comparable U.S. companies.
                               The Portfolio may engage in certain foreign currency, options and
                               futures transactions to attempt to hedge against the overall
                               level of investment and currency risk associated with its present
                               or planned investments. Such transactions involve certain risks
                               and transaction costs.
                               The Portfolio may invest up to 5% of its total assets in below
                               investment grade debt securities. Investments of this type are
                               subject to a greater risk of loss of principal and interest.

</TABLE>
    
 
- --------------
   
(1)  THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit each Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 1.50% of the average daily net assets of the Fund's Advisor
    Class shares. Without reimbursements, "Other Expenses" and "Total Fund
    Operating Expenses" would have been 0.88% and 1.86%, respectively, for
    Advisor Class shares of the Fund. "Other expenses" include custody, transfer
    agency, legal, audit and other operating expenses. See "Management" herein
    and the Statement of Additional Information for more information. Investors
    purchasing Advisor Class shares through financial planners, trust companies,
    bank trust departments or registered investment advisers, or under a "wrap
    fee" program, will be subject to additional fees charged by such entities or
    by the sponsors of such programs. Where any account advised by one of the
    companies composing or affiliated with AMVESCAP PLC invests in Advisor Class
    shares of the Fund, such account shall not be subject to duplicative
    advisory fees.
    
 
   
    The Board of Trustees of the Trust believes that the aggregate per share
    expenses of the Fund and its Portfolio will be approximately equal to the
    expenses the Fund would incur if its assets were invested directly in the
    type of securities being held by the Portfolio.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds. The 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.

PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quotes. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that operate in the financial services industries. The Portfolio's investment
objective is identical to that of the Fund. There can be no assurance that the
Fund or Portfolio will achieve its investment objective.
    
 
   
At least 65% of the Portfolio's total assets normally will be invested in common
and preferred stocks and warrants to acquire such securities issued by financial
services companies. A "financial services" company is an entity in which (i) at
least 50% of either the revenues or earnings was derived from financial services
activities, or (ii) at least 50% of the assets was devoted to such activities,
based on the company's most recent fiscal year. The remainder of the Portfolio's
assets may be invested in debt securities issued by financial services companies
and/or equity and debt securities of companies outside of the financial services
industries, which, in the opinion of the Sub-adviser, stand to benefit from
developments in the financial services industries.
    
 
GLOBAL FINANCIAL SERVICES INDUSTRIES INVESTMENT. Examples of financial services
companies include commercial banks and savings institutions and loan
associations and their holding companies; consumer and industrial finance
companies; diversified financial services companies; investment banks; insurance
brokerages; securities brokerage and investment advisory companies; real estate-
related companies; leasing companies; and a variety of firms in all segments of
the insurance field such as multi-line, property and casualty and life insurance
and insurance holding companies.
 
   
The Sub-adviser believes an accelerating rate of global economic interdependence
will lead to significant growth in the demand for financial services. In
addition, in the Sub-adviser's view, as the industries evolve, opportunities
will emerge for those companies positioned for the future. Thus, the Sub-adviser
expects that banking and related financial institution consolidation in the
developed countries, increased demand for retail borrowing in developing
countries, a growing need for international trade-based financing, a rising
demand for sophisticated risk management, the proliferating number of liquid
securities markets around the world, and larger concentrations of investable
assets should lead to growth in financial service companies that are positioned
for the future.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the
financial services industries are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets located throughout the world and the substantial global
resources of AMVESCAP PLC in attempting to identify those countries and
companies then providing the greatest potential for long-term capital
appreciation. In this fashion, the Sub-adviser seeks to enable shareholders to
capitalize on the substantial investment opportunities and the potential for
long-term growth of capital presented by the global financial services
industries represented in the Portfolio.
    
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 40% of the Portfolio's total assets.
    
 
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average
 
                               Prospectus Page 7
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
per share earnings growth; high return on invested capital; a healthy balance
sheet; sound financial and accounting policies and overall financial strength;
strong competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Portfolio's sale of securities together with
its commitment (for which the Portfolio may receive a fee) to purchase similar,
but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolio to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other
    
 
                               Prospectus Page 8
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
collateral as permitted by the Portfolio's investment program and regulatory
agencies, and as approved by the Board. The risks in lending portfolio
securities, as with other extensions of secured credit, consist of possible
delays in receiving additional collateral or in recovery of the securities and
possible loss of rights in the collateral should the borrower fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Portfolio's holdings. The Portfolio also may purchase stock
index futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The
Portfolio may use interest rate futures contracts and options thereon to hedge
the debt portion of its portfolio against changes in the general level of
interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of
    
 
                               Prospectus Page 9
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
Additional Information. Unless specifically noted, the Fund's investment
policies described in this Prospectus and in the Statement of Additional
Information may be changed by the Trust's Board of Trustees without shareholder
approval. The Fund's policies regarding concentration and lending, and the
percentage of the Fund's assets that may be committed to borrowing, are
fundamental policies and may not be changed without shareholder approval. The
investment policies of the Fund are identical to the investment policies of the
Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because the Fund will invest only in the Portfolio, the Fund's shareholders will
acquire only an indirect interest in the investments of the Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may experience different
returns than investors in another investment company that invests exclusively in
the Portfolio. As of the date of this Prospectus, the Fund is the only
institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities positions. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the financial services
industries, an investment in it may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
Moreover, the value of the shares of the Fund will be especially susceptible to
factors affecting the financial services industries. Accordingly, the Fund
should not be considered a complete investment program.
    
 
   
FINANCIAL SERVICES INDUSTRIES. Financial services industries may be subject to
greater governmental regulation than many other industries and changes in
governmental policies and the need for regulatory approvals may have a material
effect on the services offered by companies in the financial services
industries. Governmental regulation may limit both the financial commitments
banks can make, including the amounts and types of loans, and the interest rates
and fees they can charge. In addition, governmental regulation in certain
foreign countries may impose interest rate controls, credit controls and price
controls.
    
 
Companies in the financial services sector are subject to rapid business
changes, significant competition, value fluctuations due to the concentration of
loans in particular industries significantly affected by economic conditions
(such as real estate or energy) and volatile performance dependent upon the
availability and cost of capital and prevailing interest rates. In addition,
general economic conditions significantly affect these companies. Credit and
other losses resulting from the financial difficulty of borrowers or other third
parties potentially may have an adverse effect on companies in these industries.
Foreign banks, particularly those of Japan, have reported financial difficulties
attributed to increased competition, regulatory changes, and general economic
difficulties.
 
The financial services area in the United States currently is changing
relatively rapidly as existing distinctions between various financial service
segments become less clear. For instance, recent business combinations have
included insurance, finance, and securities brokerage under single ownership.
Some primarily retail corporations have expanded into securities and insurance
fields. Investment banking, securities brokerage and investment advisory
companies are subject to government regulation and risk due to securities
trading and underwriting activities.
 
Many of the investment considerations discussed in connection with banks,
savings institutions and loan associations, and finance companies also apply to
insurance companies. The performance of insurance company investments will be
subject to risk from several factors. The earnings of insurance companies will
be affected by interest rates, pricing (including severe pricing competition
from time to time), claims activity, marketing competition and general economic
conditions. Particular insurance lines also will be influenced by specific
matters. Property and casualty insurer profits may be affected by certain
weather catastrophes and other disasters. Life and health insurer profits may be
affected by mortality and morbidity rates. Individual companies may be exposed
to material risks, including reserve inadequacy, problems in investment
portfolios (due to real estate or "junk" bond holdings, for example), and the
inability to collect from reinsurance carriers. Insurance companies are subject
to extensive governmental regulation, including the imposition of maximum rate
levels, which may not be adequate for
some lines of business. Proposed or potential
anti-trust or tax law changes also may affect
 
                               Prospectus Page 11
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
   
adversely insurance companies' policy sales, tax obligations and profitability.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Portfolio's interest and dividends from foreign issuers may be
subject to non-U.S. withholding taxes, thereby reducing the Portfolio's net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 5% of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
 
                               Prospectus Page 12
<PAGE>
                       AIM GLOBAL FINANCIAL SERVICES FUND
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if it did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to

                       AIM GLOBAL FINANCIAL SERVICES FUND
   
use forward currency contracts are different from those needed to select the
securities in which the Portfolio invests; (4) lack of assurance that a liquid
secondary market will exist for any particular option, futures contract or
option thereon at any particular time; (5) the possible loss of principal under
certain conditions; and (6) the possible inability of the Portfolio to purchase
or sell a portfolio security at a time when it would otherwise be favorable for
it to do so, or the possible need for the Portfolio to sell a security at a
disadvantageous time, due to the need for the Portfolio to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the investment objective and policies of the Fund
and the Portfolio and to the general supervision of the Boards. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers and administrators to the Fund and the
Portfolio include, but are not limited to, determining the composition of the
investment portfolio of the Portfolio and placing orders to buy, sell or hold
particular securities. In addition, AIM and the Sub-adviser provide the
following administration services to the Portfolio and the Fund: furnishing
corporate officers and clerical staff; providing office space, services and
equipment; and supervising all matters relating to the Portfolio's and the
Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by the Portfolio to AIM and
the Sub-adviser. The Portfolio pays AIM a fee, based on the Portfolio's average
daily net assets at the annualized rate of .725% on the first $500 million, .70%
on the next $500 million, .675% on the next $500 million and .65% on all amounts
thereafter. Out of its aggregate fees payable by the Fund and the Portfolio, AIM
pays the Sub-adviser sub-advisory and sub-administration fees equal to 40% of
the aggregate fees AIM receives from the Fund and the Portfolio. The investment
management and administration fees paid by the Fund and the Portfolio are higher
than those paid by most mutual funds. The Fund pays all expenses not assumed by
AIM, the Sub-adviser, AIM Distributors or other agents. AIM has undertaken to
limit the Fund's expenses (exclusive of brokerage commissions, taxes, interest
and extraordinary expenses) to the

shares.

The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
 
taking advantage of its investment resources around the world.
    
 
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

                            ------------------------
 
   
In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
Advisor Class shares of the Fund. Certain Trustees and officers of the Trust are
affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Company acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund when issued are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in
    
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.

    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                               affiliates provide investment management and/or administrative services to institutional, corporate

                               Pursuant to a separate prospectus, the Fund also offers Class A and Class B shares, which represent
                               interests in the Fund. The Class A and Class B shares have different distribution arrangements.
 
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               Funds in the AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."
 
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at net asset value
                               on any business day. See "How to Redeem Shares."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a monthly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objectives. The Fund's net asset
                               value will fluctuate, reflecting fluctuations in the market value of its portfolio holdings. The
                               value of debt securities held by the Fund generally fluctuates inversely with interest rate
                               movements.
 
                               The Fund will invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agent, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information. Investors purchasing Advisor Class shares
    through financial planners, trust companies, bank trust departments or
    registered investment advisers, or under a "wrap fee" program, will be
    subject to additional fees charged by such entities or by the sponsors of
    such programs. Where any account advised by one of the companies composing
    or affiliated with AMVESCAP PLC invests in Advisor Class shares of the Fund,
    such account shall not be subject to duplicative advisory fees.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
                       AIM GLOBAL GOVERNMENT INCOME FUND
                  (FORMERLY GT GLOBAL GOVERNMENT INCOME FUND)
 
                                 [TO BE ADDED]
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of the net asset value per share for
Advisor Class shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance

is a function of its portfolio management in selecting the type and quality of
portfolio securities and is affected by operating expenses of the Fund as well
as by general market conditions.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund seeks a high level of current income by investing primarily in high
quality debt securities of the U.S. and foreign governments, their agencies and
instrumentalities. Its secondary objectives are capital appreciation and
protection of principal through active management of its maturity structure and
currency exposure. There can be no assurance that the Fund will achieve its
investment objective.
    
 
   
At least 65% of the Fund's total assets normally are invested in debt
obligations issued or guaranteed by the U.S. or foreign governments (including
foreign states, provinces or municipalities) or their agencies, authorities or
instrumentalities including mortgage-backed securities issued by agencies or
instrumentalities of the U.S. Government or by foreign governments. For purposes
of this policy, the Fund considers debt obligations of supranational entities
organized or supported by several national governments, such as the World Bank
and the Asian Development Bank, to be "government securities."
    
 
   
The Fund invests primarily in high quality government debt securities. "High
quality" debt securities are those rated in the top two ratings categories of
Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's, a division of
The McGraw-Hill Companies, Inc. ("S&P"), or, if not rated, determined to be of
comparable quality by the Sub-adviser. A description of Moody's and S&P ratings
is included in the Appendix to this Prospectus.
    
 
   
The Fund currently contemplates that it will invest principally in obligations
of the United States, Canada, Japan, the Western European nations, New Zealand
and Australia, as well as in multinational currency units. Under normal market
conditions, the Fund invests in issues of not less than three different
countries; investments in the securities of any one country, other than the
United States, normally represent no more than 40% of the Fund's total assets.
The Fund will not invest in a foreign currency or in securities denominated in a
foreign currency if such currency is not at the time of investment considered by
the Sub-adviser to be fully exchangeable into U.S. dollars (or a multinational
currency unit) without legal restriction.
    
 
   
The Fund may also invest up to 35% of its total assets in: (1) foreign
government securities that are not high quality but are rated at least
"investment grade," i.e., rated within the four highest ratings categories of
Moody's or S&P or, if not rated, determined by the Sub-adviser to be of
comparable quality; (2) corporate debt obligations of U.S. or foreign issuers
rated at least investment grade by Moody's or S&P, including debt obligations
convertible into equity securities or having attached warrants or rights to
purchase equity securities; (3) privately issued mortgage-backed and asset-
backed securities that are rated at least investment grade by Moody's or S&P, or
if unrated, determined by the Sub-adviser to be of comparable quality; and (4)
common stocks, preferred stocks and warrants to acquire such securities,
provided that the Fund will not invest more than 20% of its total assets in such
securities.
    
 
   
                                GENERAL POLICIES
    
 
   
ASSET ALLOCATION. The Fund invests in debt obligations allocated among diverse
markets and denominated in various currencies, including U.S. dollars, or in
multinational currency units such as Euros. The Fund is designed for investors
who wish to accept the risks entailed in such investments, which are different
from those associated with a portfolio consisting entirely of securities of U.S.
issuers denominated in U.S. dollars. The Fund may purchase securities that are
issued by the government or a company or financial institution of one country
but denominated in the currency of another country (or a multinational currency
unit).
    
 
   
The Sub-adviser allocates the assets of the Fund in securities of issuers in
countries and in currency denominations where the combination of fixed income
market returns, the price appreciation potential of fixed income securities and
currency exchange rate movements will present opportunities
    
 
                               Prospectus Page 6
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
primarily for high current income and secondarily for capital appreciation (and
in the case of the Fund, secondarily for Capital Appreciation and protection of
principal). In so doing, the Sub-adviser intends to take full advantage of the
different yield, risk and return characteristics that investment in the fixed
income markets of different countries can provide for U.S. investors.
Fundamental economic strength, credit quality and currency and interest rate
trends are the principal determinants of the emphasis given to various country,
geographic and industry sectors within the Fund. Securities held by the Fund may
be invested without limitation as to maturity.
    
 
   
The Sub-adviser selects securities of particular issuers on the basis of its
views as to the best values then currently available in the marketplace. Such
values are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political developments and variations in the supply of funds available
for investment in the world bond market relative to the demands placed upon it.
    
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation, interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Sub-adviser may seek to protect the Fund
against such negative currency movements through the use of sophisticated
investment techniques. See "Options, Futures and Forward Currency Transactions."
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the value of all outstanding government debt obligations throughout the world
is represented by obligations denominated in currencies other than the U.S.
dollar. Moreover, from time to time, the debt securities of issuers located
outside the United States have substantially outperformed the debt obligations
of U.S. issuers. Accordingly, the Sub-adviser believes that the Fund's policy of
investing in debt securities throughout the world may enable the achievement of
results superior to those produced by mutual funds with similar objectives to
those of the Fund that invest solely in debt securities of U.S. issuers.
    
 
   
The Fund is designed for investors who wish to accept the risks entailed in such
investments, which are different from those associated with a portfolio
consisting entirely of securities of U.S. issuers denominated in U.S. dollars.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Sub-adviser may employ a temporary defensive
investment strategy if it determines such a strategy to be warranted due to
market, economic or political conditions. Pursuant to such a defensive strategy,
the Fund temporarily may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and/or invest up to 100% of its assets in high
quality debt securities or money market instruments of U.S. or foreign issuers.
In addition, for temporary defensive purposes, most or all of the Fund's
investments may be made in the United States and denominated in U.S. dollars. To
the extent the Fund employ a temporary defensive strategy, it will not be
invested so as to achieve directly its investment objectives. In addition,
pending investment of proceeds from new sales of Fund shares or to meet ordinary
daily cash needs, the Fund may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and may invest in high quality foreign or domestic
money market instruments. For a full description of money market instruments,
see "Selection of Debt Investments" in the "Investment Objectives and Policies"
section of the Statement of Additional Information.
    
 
   
BRADY BONDS. The Fund may invest in "Brady Bonds," which are debt restructurings
that provide for the exchange of cash and loans for newly issued bonds. Brady
Bonds have been issued by the countries of Albania, Argentina, Brazil, Bulgaria,
Costa Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria,
Panama, Peru, Philippines, Poland, Uruguay, Venezuela and Vietnam and are
expected to be issued by other emerging market countries. As of the date of this
Prospectus, the Fund is not aware of the occurrence of any payment defaults on
Brady Bonds. Investors should recognize, however, that Brady Bonds do not have a
long payment history. In addition, Brady Bonds are often rated below investment
grade.
    
 
   
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling
    
 
                               Prospectus Page 7
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
interest payments based on the applicable interest rate at the time of issuance
and is adjusted at regular intervals thereafter.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The Fund may invest in
mortgage-backed and asset-backed securities of U.S. and foreign issuers,
including privately issued mortgage-backed and asset-backed securities.
Mortgage-backed securities represent direct or indirect interests in pools of
underlying mortgage loans that are secured by real property. Investors typically
receive payments out of the interest on and principal of the underlying
mortgages. Asset-backed securities are similar to mortgage-backed securities,
except that the underlying assets are other financial assets or financial
receivables, such as motor vehicle installment sales contracts, home equity
loans, leases of various types of real and personal property, and receivables
from credit cards. Any mortgage-backed and asset-backed securities purchased by
the Fund will be subject to the same rating requirements that apply to its other
investments. In addition, privately issued mortgage-backed and asset-backed
securities purchased by the Fund will be subject to the limitation of the Fund
which allows no more than 35% of its total assets to be invested in securities
of non-governmental issuers.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery of the securities. If the
Fund disposes of the right to acquire a when-issued security prior to its
acquisition or disposes of its right to deliver or receive against a forward
commitment, it may incur a gain or loss. At the time the Fund enters into a
transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss. The Fund may invest up to 5% of its total assets in a
combination of securities purchased on a when-issued basis or with respect to
which it has entered into forward commitment agreements.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemption of Fund
shares. The Fund also may borrow up to 5% of its total assets for temporary or
emergency purposes other than to meet redemptions. However, the Fund will not
borrow for investment purposes, nor will the Fund purchase securities while
borrowings are outstanding.
    
 
   
The Fund may also enter into reverse repurchase agreements with a bank or
recognized securities dealer. Under a reverse repurchase agreement, the Fund
would sell securities and agree to repurchase them at a particular price at a
future date. At the time the Fund enters into a reverse repurchase agreement, it
will establish and maintain a segregated account with an approved custodian
containing cash or liquid securities having a value not less than the repurchase
price, including accrued interest. Reverse repurchase agreements involve the
risk that the market value of the securities retained in lieu of sale by the
Fund may decline below the price of the securities the Fund has sold but is
obligated to repurchase. In the event the buyer of securities under a reverse
repurchase agreement files for bankruptcy or becomes insolvent, such buyer or
its trustee or receiver may receive an extension of time to determine whether to
enforce the Fund's obligation to repurchase the securities, and the Fund's use
of the proceeds of the reverse repurchase agreement may effectively be
restricted pending such decision.
    
 
   
The Fund also may enter into "dollar rolls," in which the Fund sells fixed
income securities for delivery in the current month and simultaneously contracts
to repurchase substantially similar (same type, coupon and maturity) securities
on a specified future date. During the roll period, the Fund would forego
principal and interest paid on such securities. The Fund would be compensated by
the difference between the current sales price and the forward price for the
future purchase, as well as by the interest earned on the cash proceeds of the
initial sale. See "Investment Objectives and Policies" in the Statement of
Additional Information.

<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
 
   
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Fund's assets for purposes of calculating compliance
with the Fund's borrowing limitation. See "Investment Limitations" in the
Statement of Additional Information.
    
 
   
SECURITIES LENDING. The Fund may lend its respective portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Fund to retain ownership of the securities loaned and, at the same time,
enhances the Fund's total return. At all times a loan is outstanding, the Fund
requires the borrower to maintain with the Fund's custodian, collateral
consisting of cash, U.S. government securities, or certain irrevocable letters
of credit equal to at least the value of the borrowed securities, plus any
accrued interest or such other collateral as permitted by the Fund's investment
program and regulatory agencies, and as approved by the Board. The Fund limits
its loans of portfolio securities to an aggregate of 30% of the value of its
total assets, measured at the time any such loan is made. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the loaned
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. It may also invest in zero
coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
interest in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the "interest" on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
must be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
SYNTHETIC SECURITY POSITIONS. The Fund may utilize combinations of futures on
bonds and forward currency contracts to create investment positions that have
substantially the same characteristics as bonds of the same type as those on
which the futures contracts are written. Investment positions of this type are
generally referred to as "synthetic securities."
    
 
   
For example, in order to establish a synthetic security position for the Fund
that is comparable to owning a Japanese government bond, the Sub-adviser might
purchase futures contracts on Japanese government bonds in the desired principal
amount and purchase forward currency contracts for Japanese Yen in an amount
equal to the then current purchase price for such bonds in the Japanese cash
market, with each contract having approximately the same delivery date.
    
 
   
The Sub-adviser might roll over the futures and forward currency contract
positions before taking delivery in order to continue the Fund's investment
position, or the Sub-adviser might close out those positions, thus effectively
selling the synthetic security. Further, the amount of each contract might be
adjusted in response to market conditions and the forward currency contract
might be changed in amount or eliminated in order to hedge against currency
fluctuations.
    
 
   
The Sub-adviser would create synthetic security positions for the Fund when it
believes that it can obtain a better yield or achieve cost savings in comparison
to purchasing actual bonds or when comparable bonds are not readily available in
the market. Synthetic security positions are subject to the risk that changes in
the value of purchased futures contracts may differ from changes in the value of
the bonds that might otherwise have been purchased in the cash market. Also,
while the Sub-adviser believes that the cost of creating synthetic security
positions generally will be materially lower than the cost of acquiring
comparable bonds in the cash market, the Fund will incur transaction costs in
connection with each purchase of a futures or forward currency contract. The use
of futures contracts and forward currency contracts to create synthetic security
positions also is subject to substantially the same risks as those that exist
when

these instruments are used in connection with hedging strategies. See "Options,
Futures and Forward Currency Transactions" below and "Options, Futures and
Currency Strategies" in the Statement of Additional Information.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies, and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the Fund's investment. The Fund may enter into such instruments
up to the full value of its portfolio assets. See "Risk Factors -- Options,
Futures and Currency Transactions" herein and "Options, Futures and Currency
Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund may also purchase and sell put and call
options on currencies, futures contracts on currencies and options on such
futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on securities
to hedge against the risk of fluctuations in the prices of securities held by
the Fund or that the Sub-adviser intends to include in the Fund's portfolio. The
Fund also may purchase and sell put and call options on indices to hedge against
overall fluctuations in the securities markets generally or in a specific market
sector.
    
 
   
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or market sector decline that could adversely affect the Fund's
portfolio. The Fund also may purchase index futures contracts and purchase call
options or write put options on such contracts to hedge against a general market
or market sector advance and thereby attempt to lessen the cost of future
securities acquisitions. The Fund may use interest rate futures contracts and
options thereon to hedge its portfolio against changes in the general level of
interest rates.
    
 
   
OTHER INDEXED SECURITIES. The Fund may invest in certain indexed securities,
which are securities whose prices are indexed to the prices of other securities,
securities indices, currencies, precious metals or other commodities, or other
financial indicators. Indexed securities typically, but not always, are debt
securities or deposits whose value at maturity or coupon rate is determined by
reference to a specific instrument or statistic. The performance of indexed
securities depends to a great extent on the performance of the security,
currency, or other instrument to which they are indexed, and may also be
influenced by interest rate changes in the United States and abroad. At the same
time, indexed securities are subject to the credit risks associated with the
issuer of the security, and their values may decline substantially if the
issuer's creditworthiness deteriorates. Indexed securities may be more volatile
than the underlying instruments. New forms of indexed securities continue to be
developed. The Fund may invest in such securities to the extent consistent with
its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. The
Fund's other investment policies described herein and in the Statement of
Additional Information may be changed by the Trust's Board of Trustees without
shareholder approval.
    
 
   
The Fund is authorized to make short sales of securities, although it has no
current intention of doing so. See "Investment Objectives and Policies -- Short
Sales" in the Statement of Additional Information.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objectives. The Fund's net asset value will fluctuate, reflecting fluctuations
in the market value of its portfolio positions and its net currency exposure.
The value of fixed income securities held by the Fund generally fluctuates
inversely with interest rate movements. Longer term bonds held by the Fund are
subject to greater interest rate risk.
    
 
   
NON-DIVERSIFIED CLASSIFICATION. The Fund is classified under the Investment
Company Act of 1940 (the "1940 Act") as a "non-diversified" fund. As a result,
the Fund will be able to invest in a fewer number of issuers than if it were
classified under the 1940 Act as a "diversified" fund. To the extent that the
Fund invests in a smaller number of issuers, the value of the Fund's shares may
fluctuate more widely and the Fund may be subject to greater investment and
credit risk with respect to its portfolio.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies. In addition, certain costs
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Fund's interest and dividends from foreign
issuers may be subject to non-U.S. withholding taxes, thereby reducing its net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the investments of the Fund in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
CURRENCY RISK. Since the Fund normally invests substantially in securities
denominated in currencies other than the U.S. dollar, and because it may hold
foreign currencies, it will be affected favorably or unfavorably by exchange
control regulations or changes in the exchange rates between such currencies and
the U.S. dollar. Changes in currency exchange rates will influence the value of
the Fund's shares, and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by the Fund. Currencies
generally are evaluated on the basis of fundamental economic criteria (e.g.,
relative inflation and interest rate levels and trends, growth rate forecasts,
balance of payments status and economic policies) as well as technical and
political data. The exchange rates between the U.S. dollar and other currencies
are determined by supply and demand in the currency exchange markets, the
international balance of payments, governmental intervention, speculation and
other economic and political conditions. If the currency in which a security is
denominated appreciates against the U.S. dollar, the dollar value of the
security will increase. Conversely, a decline in the exchange rate of the
currency would adversely affect the value of the security expressed in U.S.
dollars.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The yield characteristics of
mortgage-backed and asset-backed securities differ from those of traditional
bonds. Among the major differences are that interest and principal payments are
made more frequently (usually monthly) and that principal may be prepaid at any
time because the underlying mortgage loans or other assets generally may be
prepaid at any time. Generally, prepayments on fixed-rate mortgage loans will
increase during a period of falling interest rates and decrease during a period
of rising interest rates. Mortgage-backed and asset-backed securities may also
    
 
                               Prospectus Page 11
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
decrease in value as a result of increasing market interest rates and, because
of prepayments, may benefit less than other bonds from declining interest rates.
Reinvestments of prepayments may occur at lower interest rates than the original
investment, thus adversely affecting the yield of the Fund. Actual prepayment
experience may cause the yield of a mortgage-backed security to differ from what
was assumed when the Fund purchased the security. The market for privately
issued mortgage-backed and asset-backed securities is smaller and less liquid
than the market for U.S. government mortgage-backed securities.
    
 
   
Foreign mortgage-backed securities markets are substantially smaller than U.S.
markets, but have been established in several countries, including Germany,
Denmark, Sweden, Canada and Australia, and may be developed elsewhere. Foreign
mortgage-backed securities generally are structured similar to domestic
mortgage-backed securities, and they normally present substantially similar
investment risks as well as the other risks normally associated with foreign
securities.
    
 
   
SOVEREIGN DEBT. The Fund may invest in sovereign debt securities of emerging
market governments, including Brady Bonds. Investments in such securities
involve special risks. The issuer of the debt or the governmental authorities
that control the repayment of the debt may be unable or unwilling to repay
principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn the Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
   
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
    
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's investments.
Emerging markets are faced with social and political issues and some of them
have experienced high rates of inflation in recent years and have extensive
internal debt. Among other effects, high inflation and internal debt service
requirements may adversely affect the cost and availability of future domestic
sovereign borrowing to finance governmental programs, and may have other adverse
social, political and economic consequences. Political changes or a
deterioration of a country's domestic economy or balance of trade may affect the
willingness of countries to service their sovereign debt. Although the
Sub-adviser intends to manage the Fund in a manner that will minimize the
exposure to such risks, there can be no assurance that adverse political changes
will not cause the Fund to suffer a loss of interest or principal on any of its
holdings.
    
 
   
In recent years, some of the emerging market countries in which the Fund expects
to invest have encountered difficulties in servicing their sovereign debt
obligations. Some of these countries have withheld payments of interest and/or
principal of sovereign debt. These difficulties have also led to agreements to
restructure external debt obligations -- in particular, commercial bank loans,
typically by rescheduling principal payments, reducing interest rates and
extending new credits to finance interest payments on existing debt. In the
future, holders of emerging market sovereign debt securities may be requested to
participate in similar rescheduling of such debt. Certain emerging market
countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by
    
 
                               Prospectus Page 12
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
   
which a creditor may collect in whole or in part sovereign debt on which an
emerging market government has defaulted.
    
 
   
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
    
 
   
Investors should also be aware that certain sovereign debt instruments in which
the Fund may invest involve great risk. As noted above, sovereign debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to securities rated below investment grade by
Moody's and S&P. Such securities are regarded as predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligations and involve major risk exposure to
adverse conditions. Some of such securities, with respect to which the issuer
currently may not be paying interest or may be in payment default, may be
comparable to securities rated D by S&P or C by Moody's. The Fund may have
difficulty disposing of and valuing certain sovereign debt obligations because
there may be a limited trading market for such securities. Because there is no
liquid secondary market for many of these securities, the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets or in the appropriate
market sector and movements in interest rates and currency markets; (2)
imperfect correlation, or even no correlation, between movements in the price of
options, forward contracts, futures contracts or options thereon and movements
in the price of the currency or security hedged or used for cover; (3) the fact
that skills and techniques needed to trade options, futures contracts and
options thereon or to use forward currency contracts are different from those
needed to select the securities in which the Fund invests; (4) lack of assurance
that a liquid secondary market will exist for any particular option, futures
contract or option thereon at any particular time; (5) the possible loss of
principal under certain conditions; and (6) the possible inability of the Fund
to purchase or sell a portfolio security at a time when it would otherwise be
favorable for it to do so, or the possible need for the Fund to sell a security
at a disadvantageous time, due to the need for the Fund to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets, in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.

- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust and persons or companies furnishing services to the Fund,
including the investment management and administrative services agreement with
AIM, the investment sub-advisory and sub-administration agreement between AIM
and the Sub-adviser, the agreements with AIM Distributors regarding distribution
of the Fund's shares, the custody agreement and the transfer agency agreement.
The day-to-day operation of the Fund is delegated to the officers of the Trust,
subject always to the investment objectives and policies of the Fund and to the
general supervision of the Trust's Board. See "Trustees and Executive Officers"
in the Statement of Additional Information for information on the Trustees of
the Trust.
    
 
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the investment portfolio of
the Fund and placing orders to buy, sell or hold particular securities. In
addition, AIM and the Sub-adviser provide the following administration services
to the Fund: furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Fund's operation.
 
   
The Fund pays AIM investment management and administration fees computed daily
and payable monthly, based on the average daily net assets, for such services at
the annualized rate of .725% on the first $500 million, .70% on the next $1
billion, .675% on the next $1 billion, and .65% on amounts thereafter. Out of
the aggregate fees payable by the Fund, AIM pays the Sub-adviser sub-advisory
and sub-administration fees equal to 40% of the aggregate fees AIM receives from
the Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or any other agents. AIM has
undertaken to limit the expenses of the Advisor Class shares of the Fund
(exclusive of brokerage commissions, taxes, interest and extraordinary expenses)
to the maximum annual rate of 1.50% of the average daily net assets of the
Fund's Advisor Class shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment advisory
agreement, dated as of May 29, 1998 (the "Advisory Agreement"). AIM was
organized in 1976 and, together with its subsidiaries, manages or advises
approximately 90 investment company portfolios encompassing a broad range of
investment objectives. The Sub-adviser, 50 California Street, 27th Floor, San
Francisco, California 94111, and 1166 Avenue of the Americas, New York, New York
10036, serves as the sub-adviser to the Fund pursuant to an investment
sub-advisory and sub-administrative agreement dated as of May 29, 1998. Prior to
May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset Management, Inc.
On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the former indirect
parent organization of the Sub-adviser, consummated a purchase agreement with
AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset Management
Division, which included the Sub-adviser and certain other affiliates. As a
result of this transaction, the Sub-adviser is now an indirect wholly owned
subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and its worldwide
asset management affiliates provided investment management and/or administrative
services to institutional, corporate and individual clients around the world
since 1969.

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions for the Fund may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust.
    
 
   
From time to time, the Trust may establish other funds, each corresponding to a
distinct investment portfolio and a distinct series of the Trust's shares.
Shares of each fund are entitled to one vote per share (with proportional voting
for fractional shares) and are freely transferable. Shareholders have no
preemptive rights. Other than the automatic conversion of Class B shares to
Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

                                   APPENDIX A
                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from "Aaa" to "C." Investment grade ratings are the four
categories shown:
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various entities in categories ranging from "AAA"
to "D" according to quality. Investment grade ratings are the four categories
shown:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
                               Prospectus Page 17
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally will be evidenced by many of
the characteristics cited above but to a lesser degree. Earnings trends and
coverage ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is

                                      A-2
<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR

the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7

                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an

    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.

portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for

    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts

Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                               clients around the world. AIM and the Sub-adviser are both indirect wholly owned subsidiaries of

                               invested in Advisor Class shares of any of the funds in The AIM Family of Funds on May 29, 1998; and
                               (e) any of the companies affiliated with AMVESCAP PLC. Pursuant to a separate prospectus, the Fund
                               also offers Class A and Class B shares, which represent interests in the Fund. The Class A and Class
                               B shares have different distribution arrangements.
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston TX 77210-4739. See "How to Purchase Shares."
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"), Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               funds in The AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at net asset value
                               on any business day. See "How to Redeem Shares."
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a quarterly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset value
                               will fluctuate, reflecting fluctuations in the market value of its portfolio holdings. The value of
                               debt securities held by the Fund generally fluctuates inversely with interest rate movements. Certain
                               investment grade debt securities may possess speculative qualities.
                               The Fund may invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agent, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information. Investors purchasing Advisor Class shares
    through financial planners, trust companies, bank trust departments or
    registered investment advisers, or under a "wrap fee" program, will be
    subject to additional fees charged by such entities or by the sponsors of
    such programs. Where any account advised by one of the companies affiliated
    with AMVESCAP PLC invests in Advisor Class shares of the Fund, such account
    shall not be subject to duplicative advisory fees.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the Hypothetical Example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.

- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
                        AIM GLOBAL GROWTH & INCOME FUND
                   (FORMERLY GT GLOBAL GROWTH & INCOME FUND)
 
                                 [TO BE ADDED]
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of net asset value per share for Advisor
Class shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                        AIM GLOBAL GROWTH & INCOME FUND
 
   
                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital appreciation together with
current income. The Fund seeks its objective by investing in a global portfolio
of both equity and debt securities, allocated among diverse international
markets. There is no assurance that the Fund will achieve its investment
objective.
    
 
   
At least 65% of the Fund's total assets normally will be invested in a
combination of blue-chip equity securities and high quality government bonds.
The Fund considers an equity security to be "blue chip" if: (i) during the
issuer's most recent fiscal year the security offered an above average dividend
yield relative to the latest reported dividend yield on the Morgan Stanley
Capital International World Index; AND (ii) the total equity market
capitalization of the issuer is at least $1 billion. Government bonds are deemed
to be high quality if at the time of the Fund's investment they are rated within
one of the two highest ratings categories of Moody's Investors Service, Inc.
("Moody's") or by Standard & Poor's, a division of The McGraw-Hill Companies,
Inc. ("S&P"), or, if not rated, are deemed to be of equivalent quality in the
judgment of the Sub-adviser.
    
 
   
Up to 35% of the Fund's total assets may be invested in other equity securities
and investment grade government and corporate debt obligations which the
Sub-adviser believes will assist the Fund in achieving its objective.
"Investment grade" debt securities are those rated within one of the four
highest ratings categories of Moody's or S&P, or, if not rated, deemed to be of
equivalent quality in the judgment of the Sub-adviser.
    
 
   
Equity securities that the Fund may purchase include common stocks, preferred
stocks and warrants to acquire such stocks and other equity securities.
Government bonds that the Fund may purchase include debt obligations issued or
guaranteed by the United States or foreign governments (including foreign
states, provinces or municipalities) or their agencies, authorities or
instrumentalities and debt obligations of supranational entities organized or
supported by several national governments, such as the World Bank and the Asian
Development Bank. The debt obligations held by the Fund may include debt
obligations convertible into equity securities or having attached warrants or
rights to purchase equity securities. The Fund may purchase securities that are
issued by the government or a corporation or financial institution of one nation
but denominated in the currency of another nation (or a multinational currency
unit).
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the total equity market capitalization worldwide is represented by non-U.S.
equity securities, and more than 50% of the value of all outstanding government
debt obligations throughout the world is represented by obligations denominated
in currencies other than the U.S. dollar. Moreover, from time to time the equity
and debt securities of issuers located outside the United States have
substantially outperformed the equity and debt securities of U.S. issuers.
Accordingly, the Sub-adviser believes that the Fund's policy of investing in a
global portfolio of equity and debt securities may enable the achievement of
long-term results superior to those produced by mutual funds with similar
objectives to that of the Fund that invest solely in U.S. equity and debt
securities.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. Consistent with the Fund's
investment objective, the Sub-adviser employs a conservative investment style in
managing the Fund's assets. In so doing the Sub-adviser attempts to limit
volatility and risk to capital. The Sub-adviser allocates the Fund's assets
among securities of countries and in currency denominations where opportunities
for meeting the Fund's investment objective are expected to be the most
attractive. The Sub-adviser attempts to identify those countries and industries
where economic and political factors are likely to produce above-average growth
rates and to further identify companies in such countries and industries that
are best positioned and managed to benefit from these factors.
    
 
   
The Fund currently contemplates that it will invest principally in securities of
issuers in the United States, Canada, Japan, Western Europe, New Zealand and
Australia. The Fund may invest substantially in securities denominated in one or
more currencies. Under normal conditions, the
    
 
                               Prospectus Page 6
<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
   
Fund invests in issuers of not less than three different countries and issuers
of any one country, other than the United States, will represent no more than
40% of the Fund's total assets.
    
 
   
The relative proportions of equity and debt securities held by the Fund at any
one time will vary, depending upon the Sub-adviser's assessment of global
political and economic conditions and the relative strengths and weaknesses of
the world equity and debt markets. To enable the Fund to respond to general
economic changes and market conditions around the world, the Fund is authorized
to invest up to 100% of its total assets in either equity securities or debt
securities.
    
 
   
In selecting equity securities for investment, the Sub-adviser attempts to
identify and acquire only securities it deems to represent high or improving
investment quality. Securities representing high investment quality generally
will include those of well-known, established and successful issuers that the
Sub-adviser believes will continue to be successful in the future. Securities
representing improving investment quality may include those of an issuer that
has improved its sales or earnings or of an issuer the balance sheet and
financial condition of which is improving. The Sub-adviser seeks to avoid
investing in equity securities that appear overly speculative or risky, even if
they have attractive features or investment potential.
    
 
   
In evaluating debt securities considered for the Fund, the Sub-adviser analyzes
their yield, maturity, issue classification and quality characteristics, coupled
with expectations regarding local and world economies, movements in the general
level and term of interest rates, currency values, political developments, and
variations in the supply of funds available for investment in the world bond
market relative to the demands placed upon it. There are no limitations on the
maximum or minimum maturities of the debt securities considered by the Fund or
on the average weighted maturity of the debt portion of the Fund's portfolio.
Should the rating of a debt security be revised while such security is owned by
the Fund, the Sub-adviser will evaluate what action, if any, is appropriate with
respect to such security.
    
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation and interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Fund may seek to protect itself against
negative currency movements by engaging in hedging techniques through the use of
options, futures and forward currency contracts.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Fund may hold cash (U.S.
dollars, foreign currencies or multinational currency units such as Euros) and/
or invest any portion or all of its assets in high quality money market
instruments of U.S. or foreign issuers. In addition, for temporary defensive
purposes, most or all of the Fund's investments may be made in the United States
and denominated in U.S. dollars. To the extent the Fund adopts a temporary
defensive posture, it will not be invested so as to directly achieve its
investment objective. In addition, pending investment of proceeds from new sales
of Fund shares or in order to meet ordinary daily cash needs, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units) and may
invest in foreign or domestic high quality money market instruments. For a full
description of money market instruments, see "Money Market Instruments" in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemption of Fund
shares. The Fund also may borrow up to 5% of its total assets for temporary or
emergency purposes other than to meet redemptions. The Fund may borrow up to
33 1/3% of its total assets. However, the Fund will not purchase securities
while borrowings in excess of 5% of the Fund's total assets are outstanding. Any
borrowing by the Fund may cause greater fluctuation in the value of its shares
than would be the case if the Fund did not borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Fund's sale of securities together with its
commitment (for which the Fund may receive a fee) to purchase similar, but not
identical, securities at a future date.

<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least 100% of the value of the
borrowed securities, plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral should the borrower fail financially.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's net investment income from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing the Fund's net investment
income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic or
economic developments which could affect the Fund's investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, rate of savings and capital reinvestment, resource
self-sufficiency and balance of payments positions. Investments in foreign
government securities involve special risks, including the risk that the
government issuers may be unable or unwilling to repay principal and interest
when due.
    
 
   
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between such currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. To attempt to increase
return, the Fund may write call options on securities. This strategy will be
employed only when, in the opinion of the Sub-adviser, the size of the premium
the Fund receives for writing the option is adequate to compensate the Fund
against the risk that appreciation in the underlying security may not be fully
realized if the option is exercised. The Fund also is authorized to write put
options to attempt to enhance return, although it does not have the current
intention of so doing.
    
 
   
The Fund may also use forward currency contracts, futures contracts, options on
securities, options on currencies, options on indices and options on futures
contracts to attempt to hedge against the overall level of investment and
currency risk normally associated with the Fund's investments. These instruments
are often referred to as "derivatives," which may be defined as financial
instruments whose performance is derived, at least in part, from the performance
of another asset (such as a security, currency, or an index of securities). The
Fund may enter into such instruments up to the full value of its portfolio
assets. See "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar, or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund also may purchase and sell put and call
options on currencies, futures contracts on
    
 
                               Prospectus Page 8
<PAGE>
                        AIM GLOBAL GROWTH & INCOME FUND
   
currencies and options on such futures contracts to hedge the Fund's portfolio
against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
stock indices to hedge against overall fluctuations in the securities markets or
in a specific market sector.
    
 
   
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or a specific market sector decline that could adversely affect the
Fund's portfolio. The Fund also may purchase index futures contracts and
purchase call options or write put options on such contracts to hedge against a
general market or market sector advance and thereby attempt to lessen the cost
of future securities acquisitions. Similarly, the Fund may use interest rate
futures contracts and options thereon to hedge the debt portion of its portfolio
against changes in the general level of interest rates.
    
 
   
Although the Fund is authorized to enter into options, futures and forward
currency transactions, the Fund might not enter into any such transactions.
Options, futures and foreign currency transactions involve certain risks, which
include: (1) dependence on the Sub-adviser's ability to predict movements in the
prices of individual securities, fluctuations in the general securities markets
and movements in interest rates and currency markets; (2) imperfect correlation,
or even no correlation, between movements in the price of forward contracts,
options, futures contracts or options thereon and movements in the price of the
currency or security hedged or used for cover; (3) the fact that the skills and
techniques needed to trade options, futures contracts and options thereon or to
use forward currency contracts are different from those needed to select the
securities in which the Fund invests; (4) the lack of assurance that a liquid
secondary market will exist for any particular option, futures contract or
option thereon at any particular time; (5) the possible loss of principal under
certain conditions; and (6) the possible inability of the Fund to purchase or
sell a portfolio security at a time when it would otherwise be favorable for it
to do so, or the possible need for the Fund to sell a security at a
disadvantageous time, due to the need for the Fund to maintain "cover" or to set
aside securities in connection with hedging transactions.
    
 
   
OTHER POLICIES AND RISKS. The Fund's net asset value will fluctuate, reflecting
fluctuations in the market value of its portfolio positions. Equity securities,
particularly common stocks, generally represent the most junior position in an
issuer's capital structure, and entitle holders to an interest in the assets of
an issuer, if any, remaining after all more senior claims have been satisfied.
The value of equity securities held by the Fund will fluctuate in response to
general market and economic developments, as well as developments affecting the
particular issuers of such securities. In addition, the value of debt securities
held by the Fund generally will fluctuate with changes in the perceived
creditworthiness of the issuers of such securities and movements in interest
rates. Investment grade debt securities rated Baa by Moody's are described by
Moody's as having speculative characteristics, and therefore may be affected by
economic conditions and changes in the circumstances of their issuers to a
greater extent than higher rated bonds.
    
 
   
The Fund may invest up to 15% of its net assets in illiquid securities and other
securities for which no readily available market exists. The Fund may also
invest up to 5% of its total assets in a combination of securities purchased on
a when-issued basis or with respect to which it has entered into forward
commitment agreements.
    
 
   
The Fund is classified under the Investment Company Act of 1940, as amended
("1940 Act") as a "non-diversified" fund. As a result, the Fund will be able to
invest in a fewer number of issuers than if it were classified under the 1940
Act as a "diversified" fund. To the extent that the Fund invests in a smaller
number of issuers, the value of the Fund's shares may fluctuate more widely and
the Fund may be subject to greater investment and credit risk with respect to
its portfolio.
    
 
   
OTHER INFORMATION. The Fund's investment objective may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the

                        AIM GLOBAL GROWTH & INCOME FUND
   
Statement of Additional Information. Unless specifically noted, the Fund's
investment policies described in this Prospectus and in the Statement of
Additional Information may be changed by the Trust's Board of Trustees without
shareholder approval. The Fund's policies regarding lending, and the percentage
of Fund assets that may be committed to borrowing, are fundamental policies and
may not be changed without shareholder approval. If a percentage restriction on
investment or utilization of assets in an investment policy or restriction is
adhered to at the time an investment is made, a later change in percentage
ownership of a security or kind of securities resulting from changing market
values or a similar type of event will not be considered a violation of the
Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day-to-day operations of the Fund are delegated to the officers
of the Trust, subject always to the objective and policies of the Fund and to
the general supervision of the Trust's Board of Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the Fund's portfolio and
placing orders to buy, sell or hold particular securities; furnishing corporate
officers and clerical staff; providing office space, services and equipment; and
supervising all matters relating to the Fund's operation. For these services,
the Fund pays AIM investment management and administration fees, computed daily
and paid monthly, based on the average daily net assets, at the annualized rate
of .975% on the first $500 million, .95% on the next $500 million, .925% on the
next $500 million and .90% on amounts thereafter. Out of the aggregate fees
payable by the Fund, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit the Fund's expenses (exclusive of brokerage commissions,
taxes, interest and extraordinary expenses) to the annual rate of 1.40% of the
average daily net assets of the Fund's Advisor Class shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San

Francisco, California 94111, and 1166 Avenue of the Americas, New York, New York
10036, serves as the sub-adviser to the Fund pursuant to an investment
sub-advisory and sub-administration agreement dated as of May 29, 1998. Prior to
May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset Management, Inc.
On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the former indirect
parent organization of the Sub-adviser, consummated a purchase agreement with
AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset Management

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser.

"Distribution Agreement"), with AIM Distributors, a registered broker-dealer and
a wholly owned subsidiary of AIM, to act as the distributor of the Advisor Class
shares of the Fund. Certain Trustees and officers of the Trust are affiliated
with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998 the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Company's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and the
Company's other funds will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is
established under a "wrap fee" program and (ii) the account holder pays the
sponsor of such program an annual fee of at least .50% of the assets in the
account; (d) accounts advised by INVESCO (NY), Inc. or one of the companies

                                      A-2
<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."

[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in

the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7

                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.

portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer

    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                               the Asset Management Division of Liechtenstein Global Trust AG, provided such accounts were invested
                               in Advisor Class shares of any of the other funds in The AIM Family of Funds that are sub-advised by
                               the Sub-adviser ("AIM Funds") on May 29, 1998; (e) any of the companies composing or affiliated with
                               AMVESCAP PLC; and (f) AIM Global Trends Fund. Pursuant to a separate prospectus, the Fund also offers
                               Class A and Class B shares, which represent interests in the Fund. The Class A and Class B shares
                               have different distribution arrangements.
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds") Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               funds in The AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at the Fund's net
                               asset value on any business day. See "How to Redeem Shares."
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset value
                               will fluctuate, reflecting fluctuations in the market value of its Portfolio's portfolio holdings.
                               The Fund's policy of concentrating its investments in companies in its particular industries may
                               cause the Fund's net asset value to fluctuate more than if it invested in a greater number of
                               industries.
                               The Fund may invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 1.50% of the average daily net assets of the Fund's Advisor
    Class shares. "Other expenses" include custody, transfer agency, legal,
    audit and other operating expenses. See "Management" herein and the
    Statement of Additional Information for more information. Investors
    purchasing Advisor Class shares through financial planners, trust companies,
    bank trust departments or registered investment advisers, or under a "wrap
    fee" program, will be subject to additional fees charged by such entities or
    by the sponsors of such programs. Where any account advised by one of the
    companies composing or affiliated with AMVESCAP PLC invests in Advisor Class
    shares of the Fund, such account shall not be subject to duplicative
    advisory fees.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S ACTUAL EXPENSES, AND AN INVESTOR'S DIRECT AND INDIRECT
    EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The table and the assumption
    in the Hypothetical Example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a

The tables below provide condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital appreciation. It seeks its
objective by investing primarily in equity securities of health care companies
throughout the world. There can be no assurance that the Fund will achieve its
investment objective.
    
 
   
At least 65% of the Fund's total assets normally will be invested in common and
preferred stocks, and warrants to acquire such securities, issued by health care
companies. A "health care" company is an entity in which (i) at least 50% of
either the revenues or earnings was derived from health care activities, or (ii)
at least 50% of the assets was devoted to such activities, based on the
company's most recent fiscal year. The remainder of the Fund's assets may be
invested in debt securities issued by health care companies and/or equity and
debt securities of companies outside of the health care industry, which, in the
opinion of the Sub-adviser, stand to benefit from developments in the health
care industries.
    
 
   
GLOBAL HEALTH CARE INDUSTRIES INVESTMENT. Examples of health care companies
include those that are substantially engaged in the design, manufacture or sale
of products or services used for or in connection with health care or medicine.
Such firms may include pharmaceutical companies; firms that design, manufacture,
sell or supply medical, dental and optical products, hardware or services;
companies involved in biotechnology, medical diagnostic, and biochemical
research and development; and companies involved in the ownership and/or
operation of health care facilities.
    
 
   
The Fund expects that, from time to time, a significant portion of its assets
may be invested in the securities of U.S. issuers. Health care industries,
however, are global industries with significant, growing markets outside of the
United States. A sizeable portion of the companies which comprise the health
care industries are headquartered outside of the United States, and many
important pharmaceutical and biotechnology discoveries and technological
breakthroughs have occurred outside of the United States, primarily in Japan,
the United Kingdom and Western Europe.
    
 
   
The Sub-adviser believes that the global health care industries offer attractive
long-term supply/ demand dynamics. While the United States, Western Europe, and
Japan presently account for a substantial portion of health care expenditures,
this should change dramatically in the coming decade if the populations of
developing countries devote an increasing percentage of income to health care.
Additionally, the Sub-adviser believes demographics on aging point to a
significant increase in demand from the industrialized nations, as the elderly
account for a growing proportion of worldwide health care spending. Finally, in
the Sub-adviser's view, technology will continue to expand the range of products
and services offered, with new drugs, medical devices and surgical procedures
addressing medical conditions previously considered untreatable.
    
 
   
In addition to these underlying trends, the United States is presently
experiencing a period of rapid and profound change in its own health care
system, marked by the rise of managed care, the formation of health care
delivery networks, and widespread consolidation across all segments of the
industry. The Sub-adviser believes that this transition offers investment
opportunities in those companies acting as consolidators or otherwise gaining
market share at the expense of less efficient competitors.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION.
    
   
The Fund expects that, from time to time, a significant portion of its assets
may be invested in the securities of domestic issuers. The industry represented
in the Fund, however, is a global industry with significant, growing markets
outside of the United States. A sizeable proportion of the companies which
comprise the health care industries are headquartered outside of the United
States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Fund. The Sub-adviser uses its financial expertise in
markets located throughout the world and the substantial global resources of
AMVESCAP PLC in attempting to identify those countries and companies then
providing
    
 
                               Prospectus Page 6
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
   
the greatest potential for long-term capital appreciation. In this fashion, the
Sub-adviser seeks to enable shareholders to capitalize on the substantial
investment opportunities and the potential for long-term growth of capital
presented by the global industries represented in the Fund.
    
 
   
The Sub-adviser allocates the Fund's assets among securities of countries and in
currency denominations where opportunities for meeting the Fund's investment
objective are expected to be the most attractive. The Fund may invest
substantially in securities denominated in one or more currencies. Under normal
conditions, the Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 50% of the Fund's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Fund may invest up to 100%
of its total assets in cash (U.S. dollars, foreign currencies or multinational
currency units such as Euros) and/or high quality debt securities or money
market instruments of U.S. or foreign issuers. In addition, for temporary
defensive purposes, most or all of the Fund's investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund adopts a
temporary defensive posture, it will not be invested so as to achieve directly
its investment objective. In addition, pending investment of proceeds from new
sales of Fund shares or to meet its ordinary daily cash needs, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units) and may
invest in foreign or domestic high quality money market instruments. For a full
description of money market instruments, see "Money Market Instruments" in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Fund to participate in privatizations may be limited by local law,
or the terms on which the Fund may be permitted to participate may be less
advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Fund may invest up to 10% of its
total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Fund would
bear its ratable share of that investment company's expenses, including its
advisory and administration fees. At the same time, the Fund would continue to
pay its own management fees and other expenses. AIM and the Sub-adviser will
waive their advisory fees to the extent that the Fund invests in an Affiliated
Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemptions of the
Fund's shares. The Fund also may borrow up to 5% of its total assets for
temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Fund may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Fund's borrowings exceed 5% of its
total assets. Any borrowing by the Fund may cause greater fluctuation in the
value of its shares than would be the case if the Fund did not borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed
    
 
                               Prospectus Page 7
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
   
upon price which includes an interest component. A "roll" borrowing transaction
involves the Fund's sale of securities together with its commitment (for which
the Fund may receive a fee) to purchase similar, but not identical, securities
at a future date.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least the value of the
borrowed securities, plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral should the borrower fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities or enter into forward commitments only with the
intention of actually receiving or delivering the securities, as the case may
be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery to the Fund. If
the Fund disposes of the right to acquire a when-issued security prior to its
acquisition or disposes of its right to deliver or receive against a forward
commitment, it may incur a gain or loss. At the time the Fund enters into a
transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Fund may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
stock indexes to hedge against overall fluctuations in the securities markets
generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Fund's holdings. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to
    
 
                               Prospectus Page 8
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
   
hedge against a general stock market or market sector advance and thereby
attempt to lessen the cost of future securities acquisitions. The Fund may use
interest rate futures contracts and options thereon to hedge the debt portion of
its portfolio against changes in the general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the Investment
Objectives and Policies section of the Statement of Additional Information.
    
 
- --------------------------------------------------------------------------------
 
   
                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. The Fund's net asset values will fluctuate reflecting fluctuations in
the market value of the Fund's portfolio positions. Equity securities,
particularly common stocks, generally represent the most junior position in an
issuer's capital structure, and entitle holders to an interest in the assets of
an issuer, if any, remaining after all more senior claims have been satisfied.
The value of equity securities held by the Fund will fluctuate in response to
general market and economic developments, as well as developments affecting the
particular issuers of such securities. In addition, the value of debt securities
held by the Fund generally will fluctuate with changes in the perceived
creditworthiness of the issuers of such securities and interest rates.
    
 
   
Because the Fund focuses its investments on particular industries, an investment
in each may be more volatile than that of other investment companies that do not
concentrate their investments in such a manner. Moreover, the value of the
shares of the Fund will be especially susceptible to factors affecting the
industries in which it focuses. Accordingly, the Fund should not be considered a
complete investment program.
    
 
   
HEALTH CARE INDUSTRIES. Health care industries generally are subject to
substantial governmental regulation. Changes in governmental policy or
regulation could have a material effect on the demand for products and services
offered by companies in the health care industries and therefore could affect
the performance of the Fund. Regulatory approvals are generally required before
new drugs and medical devices or procedures may be introduced and before the
acquisition of additional facilities by health care providers. In addition, the
products and services offered by such companies may be subject to rapid
obsolescence caused by technological and scientific advances.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
    
 
                               Prospectus Page 9
<PAGE>
                          AIM GLOBAL HEALTH CARE FUND
   
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's interest and dividends from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing the Fund's net investment
income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the Fund's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Fund may invest in issuers domiciled in "emerging markets." Investing in
emerging market countries involves risks in addition to those risks involved in
foreign investing. Many emerging market countries have experienced high rates of
inflation for many years. In addition, emerging markets generally are dependent
heavily upon international trade and, accordingly, have been and continue to be
affected adversely by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. The securities markets of emerging
market countries are substantially smaller, less developed, less liquid and more
volatile than the securities markets of the developed countries. In addition,
issuers in emerging markets typically are subject to a greater degree of change
in earnings and business prospects than issuers in developed countries.
    
 
   
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Funds' shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Fund may invest up to 5% of its total assets
in below investment grade debt securities, that is, rated below BBB by Standard
& Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa by
Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Fund will not invest in debt securities that
are in default as to payment of principal and interest.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
    
 
                               Prospectus Page 10

                          AIM GLOBAL HEALTH CARE FUND
   
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Fund. If an issuer exercises these provisions in a declining
interest rate market, the Fund may have to replace the security with a lower
yielding security, resulting in a decreased return for investors. In addition,
the Fund may have difficulty disposing of lower quality securities because they
may have a thin trading market. There may be no established retail secondary
market for many of these securities, and the Fund anticipates that such
securities could be sold only to a limited number of dealers or institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on market prices of such instruments and may make it more difficult for the Fund
to obtain accurate market quotations for purposes of valuing the Fund's
portfolio investments. The Fund may also acquire lower quality debt securities
during an initial underwriting or which are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Fund may also incur additional expenses to the extent it
is required to seek recovery upon a default in the payment of principal or
interest on portfolio holdings, and the Fund may have limited legal recourse in
the event of a default.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Fund to achieve
capital appreciation substantially exceeding the appreciation the Fund would
realize if it did not make such investments. However, in order to attempt to
limit investment risk, the Fund will invest no more than 5% of its total assets
in Special Situations.
    
 
   
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets or in the appropriate
market sector and movements in interest rates and currency markets; (2)
imperfect correlation, or even no correlation, between movements in the price of
options, forward contracts, futures contracts or options thereon and movements
in the price of the currency or security hedged or used for cover; (3) the fact
that skills and techniques needed to trade options, futures contracts and
options thereon or to use forward currency contracts are different from those
needed to select the securities in which the Fund invests; (4) lack of assurance
that a liquid secondary market will exist for any particular option, futures
contract or option thereon at any particular time; (5) the possible loss of
principal under certain conditions; and (6) the possible inability of the Fund
to purchase or sell a portfolio security at a time when it would otherwise be
favorable for it to do so, or the possible need for the
    
 
                               Prospectus Page 11

                          AIM GLOBAL HEALTH CARE FUND
   
Fund to sell a security at a disadvantageous time, due to the need for the Fund
to maintain "cover" or to set aside securities in connection with hedging
transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Fund's portfolio normally will include
securities of established suppliers of traditional products and services, the
Fund may invest in smaller companies which can benefit from the development of
new products and services. These smaller companies may present greater
opportunities for capital appreciation, but may also involve greater risks than
large, established issuers. Such smaller companies may have limited product
lines, markets or financial resources, and their securities may trade less
frequently and in more limited volume than the securities of larger, more
established companies. As a result, the prices of the securities of such smaller
companies may fluctuate to a greater degree than the prices of the securities of
other issuers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day-to-day operations of the Fund is delegated to the officers of
the Trust, subject always to the investment objective and policies of the Fund
and to the general supervision of the Trust's Board of Trustees. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Company's Trustees.
    
 
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the investment portfolio of
the Fund and placing orders to buy, sell or hold particular securities. In
addition, AIM and the Sub-adviser provide the following administration services
to the Fund: furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Funds' operation.
 
For investment management and administration services provided to the Fund, the
Fund pays AIM a fee computed daily and paid monthly based on the Fund's average
daily net assets at the annualized rate of .975% on the first $500 million, .95%
on the next $500 million, .925% on the next $500 million and .90% on amounts
thereafter. Out of the aggregate fees payable by the Fund, AIM pays the
Sub-adviser sub-advisory and sub-administration fees equal to 40% of the
aggregate fees AIM receives from the Fund.
 
   
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 1.50% of the average daily net assets of the Fund's Advisor Class
shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the

Americas, New York, New York 10036, serves as the sub-adviser to the Fund
pursuant to an investment sub-advisory and sub-administration agreement dated as
of May 29, 1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor
LGT Asset Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG
("LGT"), the former indirect parent organization of the Sub-adviser, consummated
a purchase agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired
LGT's Asset Management Division, which included the Sub-adviser and certain
other affiliates. As a result of this transaction, the Sub-adviser is now an
indirect wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the
Sub-adviser and its worldwide asset management affiliates provided investment
management and/or administrative services to institutional, corporate and
individual clients around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of The AIM Family of Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Funds will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Other Distributions and Tax Matters."
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware Business trust
on May 7, 1998. On September 4, 1998, the Company acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges, except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in
    
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How
                               to Purchase Shares."
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM
                               Distributors (collectively, "The AIM Family of Funds"). Advisor
                               Class shares of the Fund may be exchanged for Advisor Class
                               shares of certain funds in The AIM Family of Funds in the manner
                               and subject to the policies and charges set forth herein. See
                               "Exchange Privilege."
 
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a
                               portion of their shares at net asset value on any business day.
                               See "How to Redeem Shares."
 
Distributions:                 The Fund currently declares and pays dividends from net
                               investment income, if any, on a monthly basis. The Fund makes
                               distributions of realized capital gains, if any, on an annual
                               basis. Dividends and distributions of the Fund may be reinvested
                               at net asset value without payment of a sales charge in the
                               Fund's shares or may be invested in shares of the other funds in
                               The AIM Family of Funds. See "Dividends, Distributions and Tax
                               Matters."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve
                               its investment objectives. The Fund's net asset value will
                               fluctuate, reflecting fluctuations in the market value of its or
                               its corresponding Portfolio's securities holdings. The value of
                               debt securities held by the Portfolio generally fluctuates
                               inversely with interest rate movements.

                               The Portfolio will invest in foreign securities. Investments in
                               foreign securities involve risks relating to political and
                               economic developments abroad and the differences between the
                               regulations to which U.S. and foreign issuers are subject.
                               Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency
                               exchange rates will affect the Fund's or the Portfolio's net
                               asset value, earnings and gains and losses realized on sales of
                               securities. Securities of foreign companies may be less liquid
                               and their prices more volatile than those of securities of
                               comparable U.S. companies. The Portfolio will normally invest at
                               least 65% of its total assets in debt securities of issuers in
                               emerging markets. Such investments entail greater risks than
                               investing in securities of issuers in developed markets.
 
                               The Portfolio may engage in certain foreign currency, options and
                               futures transactions to attempt to hedge against the overall
                               level of investment and currency risk associated with its present
                               or planned investments. Such transactions involve certain risks
                               and transaction costs.
 
                               The Portfolio may invest up to 100% of its total assets in debt
                               securities rated below investment grade or, if not rated,
                               determined by the Sub-adviser to be of comparable quality.
                               Investments of this type are subject to greater risk of loss of
                               principal and interest.

(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agent, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information. Investors purchasing Advisor Class shares
    through financial planners, trust companies, bank trust departments or
    registered investment advisers, or under a "wrap fee" program, will be
    subject to additional fees charged by such entities or by the sponsors of
    such programs. Where any account advised by one of the companies composing
    or affiliated with AMVESCAP PLC invests in Advisor Class shares of the Fund,
    such account shall not be subject to duplicative advisory fees. The Board of
    Trustees of the Trust believes that the aggregate per share expenses of the
    Fund and its Portfolio will be less than or approximately equal to the
    expenses which the Fund would incur if the assets of that Fund were invested
    directly in the type of securities being held by the Portfolio.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds; the 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.

- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information. The financial statements and notes for
[        ] have been audited by [          ], independent accountants, whose
reports thereon appear in the Statement of Additional Information.
    
 
                          AIM GLOBAL HIGH INCOME FUND
                     (FORMERLY GT GLOBAL HIGH INCOME FUND)
 
                                 [TO BE ADDED]
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return. The Fund's total return shows its
overall change in value, including changes in share price and assuming all the
Fund's dividends and capital gain distributions are reinvested. A cumulative
total return reflects the Fund's performance over a stated period of time. An
average annual total return reflects the hypothetical compounded annual rate of
return that would have produced the same cumulative total return if the Fund's
performance had been constant over the entire period. BECAUSE AVERAGE ANNUAL
RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN, INVESTORS SHOULD
RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL YEAR-BY-YEAR RESULTS. To
illustrate the components of overall performance, the Fund may separate its
cumulative and average annual returns into income results and capital gains or
losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to the Fund share,
expressed as an annualized percentage of the net asset value per share for
Advisor Class shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund primarily seeks high current income, and secondarily seeks capital
appreciation. It seeks its objectives by investing all of its investable assets
in the Portfolio, which in turn seeks the same objectives as the Fund by
normally investing at least 65% of its total assets in debt securities of
issuers in emerging markets. There can be no assurance that the Fund or the
Portfolio will achieve its investment objectives.
    
 
   
The Portfolio intends to invest in the following types of debt securities:
bonds, notes and debentures of emerging market governments; securities issued or
guaranteed by such governments' agencies or instrumentalities; securities issued
or guaranteed by the central banks of emerging market countries; and securities
issued by other banks and companies in such countries and securities denominated
in or indexed to the currencies of emerging markets. Under current market
conditions, the Portfolio expects its investments in emerging market securities
to consist substantially of Brady Bonds (see "General Policies -- Brady Bonds,"
below) and other sovereign debt securities.
    
 
   
The Portfolio may also invest up to 35% of its total assets in (1) equity
securities of issuers in emerging markets included in the list below under the
caption "Emerging Markets"; (2) equity and debt securities of issuers in
developed countries, including the United States; (3) securities of issuers in
emerging markets not included in the emerging markets list, if investing therein
becomes feasible and desirable subsequent to the date of this Prospectus; and
(4) cash and money market instruments. In evaluating investments in securities
of issuers in developed markets, the Sub-adviser will consider, among other
things, the business activities of the issuer in emerging markets and the impact
that developments in emerging markets are likely to have on the issuer's
financial condition.
    
 
   
Under normal circumstances, substantially all of the Portfolio's assets will be
invested in debt securities of both governmental and corporate issuers in
emerging markets. Emerging markets debt securities generally are considered to
have a credit quality below investment grade, as defined above. Lower quality
securities involve a high degree of risk and are predominantly speculative.
These debt securities are the equivalent of high yield, high risk bonds,
commonly known as "junk bonds." See "Risk Factors." Many emerging market debt
securities are not rated by U.S. ratings agencies such as Moody's and S&P. The
Portfolio's ability to achieve its investment objectives is thus more dependent
on the Sub-adviser's credit analysis. The Portfolio may invest in securities
that are in default as to payment of principal and/or interest.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, investors
should be aware that the Fund, unlike mutual funds that directly acquire and
manage their own portfolios of securities, seeks to achieve its investment
objectives by investing all of its investable assets in the Portfolio, which is
a separate investment company. Because the Fund will invest only in the
Portfolio, the Fund's shareholders will acquire only an indirect interest in the
investments of the Portfolio.
    
 
   
The Fund may redeem its investment from the Portfolio at any time, if the Board
of Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment
objectives, policies or limitations that is not approved by the Board or the
shareholders of the Fund could require the Fund to redeem its interest in the
Portfolio. Any such redemption could result in a distribution in kind of
portfolio securities (as opposed to a cash distribution) by the Portfolio. In
addition, a distribution in kind could result in a less diversified portfolio of
investments for the Fund and could adversely affect its liquidity. Upon
redemption, the Board would consider what action might be taken, including the
investment of all the investable assets of the Fund in another pooled investment
entity having substantially the same investment objectives as the Fund or the
retention by the Fund of its own investment adviser to manage its assets in
accordance with its investment objectives, policies and limitations discussed
herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the
    
 
                               Prospectus Page 7
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
Portfolio's expenses and will invest in the Portfolio on the same terms and
conditions. However, if another investment company invests any or all of its
assets in the Portfolio, it would not be required to sell its shares at the same
public offering price as the Fund and may charge different sales commissions.
Therefore, investors in the Fund may experience different returns than investors
in another investment company that invests exclusively in the Portfolio. As of
the date of this Prospectus, the Fund is the only institutional investor in the
Portfolio.
    
 
   
Investors in the Fund should be aware that the Fund's investment in the
Portfolio may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.
    
 
   
                                GENERAL POLICIES
    
 
   
ASSET ALLOCATION. The Portfolio invests in debt obligations allocated among
diverse markets and denominated in various currencies, including U.S. dollars,
or in multinational currency units such as Euros. The Fund is designed for
investors who wish to accept the risks entailed in such investments, which are
different from those associated with a portfolio consisting entirely of
securities of U.S. issuers denominated in U.S. dollars. The Portfolio may
purchase securities that are issued by the government or a company or financial
institution of one country but denominated in the currency of another country
(or a multinational currency unit).
    
 
   
The Sub-adviser allocates the assets of the Portfolio in securities of issuers
in countries and in currency denominations where the combination of fixed income
market returns, the price appreciation potential of fixed income securities and
currency exchange rate movements will present opportunities primarily for high
current income and secondarily for capital appreciation. In so doing, the Sub-
adviser intends to take full advantage of the different yield, risk and return
characteristics that investment in the fixed income markets of different
countries can provide for U.S. investors. Fundamental economic strength, credit
quality and currency and interest rate trends are the principal determinants of
the emphasis given to various country, geographic and industry sectors within
the Portfolio. Securities held by the Portfolio may be invested in without
limitation as to maturity.
    
 
   
The Sub-adviser selects securities of particular issuers on the basis of its
views as to the best values then currently available in the marketplace. Such
values are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political developments and variations in the supply of funds available
for investment in the world bond market relative to the demands placed upon it.
    
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation, interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Sub-adviser may seek to protect the
Portfolio against such negative currency movements through the use of
sophisticated investment techniques. See "Options, Futures and Forward Currency
Transactions" and "Swaps, Caps, Floors and Collars."
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the value of all outstanding government debt obligations throughout the world
is represented by obligations denominated in currencies other than the U.S.
dollar. Moreover, from time to time, the debt securities of issuers located
outside the United States have substantially outperformed the debt obligations
of U.S. issuers. Accordingly, the Sub-adviser believes that the Portfolio's
policy of investing in debt securities of issuers in emerging markets may enable
the achievement of results superior to those produced by mutual funds with
similar objectives to those of the Fund and the Portfolio that invest solely in
debt securities of U.S. issuers.
    
 
   
The Fund is designed for investors who wish to accept the risks entailed in such
investments, which are different from those associated with a portfolio
consisting entirely of securities of U.S. issuers denominated in U.S. dollars.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Sub-adviser may employ a temporary defensive
investment strategy if it determines such a strategy to be
    
 
                               Prospectus Page 8
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
warranted due to market, economic or political conditions. Pursuant to such a
defensive strategy, the Portfolio temporarily may hold cash (U.S. dollars,
foreign currencies or multinational currency units) and/or invest up to 100% of
its respective assets in high quality debt securities or money market
instruments of U.S. or foreign issuers. In addition, for temporary defensive
purposes, most or all of the Portfolio's investments may be made in the United
States and denominated in U.S. dollars. To the extent the Portfolio employs a
temporary defensive strategy, it will not invest so as to achieve directly its
investment objectives. In addition, pending investment of proceeds from new
sales of Fund shares or to meet ordinary daily cash needs, the Portfolio may
hold cash (U.S. dollars, foreign currencies or multinational currency units) and
may invest in high quality foreign or domestic money market instruments. For a
full description of money market instruments, see "Selection of Debt
Investments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
EMERGING MARKET SECURITIES. The Portfolio considers "emerging markets" to
consist of all countries determined by the Sub-adviser to have developing or
emerging economies and markets. These countries generally include every country
in the world except the United States, Canada, Japan, Australia, New Zealand and
most countries located in Western Europe. The Portfolio will consider investment
in the following emerging markets:

</TABLE>
    
 
   
The Portfolio will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements, overly burdensome repatriation
requirements and similar restrictions, the lack of organized and liquid
securities markets, unacceptable political risks or for other reasons.
    
 
   
As used in this Prospectus and the Statement of Additional Information, an
issuer in an emerging market is an entity: (i) for which the principal
securities trading market is an emerging market, as defined above; (ii) that
(alone or on a consolidated basis) derives 50% or more of its total revenue from
either goods produced, sales made or services performed in emerging markets; or
(iii) organized under the laws of, or with a principal office in, an emerging
market.
    
 
   
BRADY BONDS. The Portfolio may invest in "Brady Bonds," which are debt
restructurings that provide for the exchange of cash and loans for newly issued
bonds. Brady Bonds have been issued by the countries of Albania, Argentina,
Brazil, Bulgaria, Costa Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan,
Mexico, Nigeria, Panama, Peru, Philippines, Poland, Uruguay, Venezuela and
Vietnam and are expected to be issued by other emerging market countries. As of
the date of this Prospectus, the Portfolio is not aware of the occurrence of any
payment defaults on Brady Bonds. Investors should recognize, however, that Brady
Bonds do not have a long payment history. In addition, Brady Bonds are often
rated below investment grade.
    
 
   
The Portfolio may invest in either collateralized or uncollateralized Brady
Bonds. U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed
rate par bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Portfolio may invest in fixed and
floating rate loans ("Loans") arranged through private negotiations between a
foreign entity and one or more financial institutions ("Lenders"). The majority
of the
    
 
                               Prospectus Page 9
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
Portfolio's investments in Loans in emerging markets is expected to be in the
form of participations in Loans ("Participations") and assignments of portions
of Loans from third parties ("Assignments"). Participations typically will
result in the Portfolio having a contractual relationship only with the Lender,
not with the borrower government. The Portfolio will have the right to receive
payments of principal, interest and any fees to which it is entitled only from
the Lender selling the Participation and only upon receipt by the Lender of the
payments from the borrower. In connection with purchasing Participations, the
Portfolio generally will have no right to enforce compliance by the borrower
with the terms of the loan agreement relating to the loan ("Loan Agreement"),
nor any rights of set-off against the borrower, and the Portfolio may not
directly benefit from any collateral supporting the Loan in which it has
purchased the Participation. As a result, the Portfolio will assume the credit
risk of both the borrower and the Lender that is selling the Participation.
    
 
   
In the event of the insolvency of the Lender selling a Participation, the
Portfolio may be treated as a general creditor of the Lender and may not benefit
from any set-off between the Lender and the borrower. The Portfolio will acquire
Participations only if the Lender interpositioned between the Portfolio and the
borrower is determined by the Sub-adviser to be creditworthy. When the Portfolio
purchases Assignments from Lenders, the Portfolio will acquire direct rights
against the borrower on the Loan. However, since Assignments are arranged
through private negotiations between potential assignees and assignors, the
rights and obligations acquired by the Portfolio as the purchaser of an
Assignment may differ from, and be more limited than, those held by the
assigning Lender.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities and forward commitments only with the
intention of actually receiving or delivering the securities, as the case may
be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery of the
securities. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
The Portfolio may also sell securities on a "when, as and if issued" basis for
hedging purposes. Under such a transaction, the Portfolio is required to deliver
at a future date a security it does not presently hold, but which it has a right
to receive if the security is issued. Issuance of the security may not occur, in
which case the Portfolio would have no obligation to the other party, and would
not receive payment for the sale. Selling securities on a "when, as and if
issued" basis may reduce risk of loss to the extent that such a sale wholly or
partially offsets unfavorable price movements on the investments being hedged.
However, such sales also limit the amount the Portfolio can receive if the
"when, as and if issued" security is in fact issued.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio is
authorized to borrow money from banks in an amount up to 33 1/3% of its total
assets (including the amount borrowed), less all liabilities and indebtedness
other than the borrowings and may use the proceeds of such borrowings for
investment purposes. The Portfolio will borrow for investment purposes only when
the Sub-adviser believes that such borrowings will benefit the Portfolio after
taking into account considerations such as the costs of the borrowing and the
likely investment returns on the securities purchased with the borrowed monies.
    
 
   
Borrowing for investment purposes is known as leveraging, which is a speculative
practice. Such borrowing by the Portfolio creates the opportunity for increased
net income and appreciation but, at the same time, involves special risk
considerations. For example, leveraging might exaggerate changes in the net
asset value of Fund shares and in the yield realized by the Portfolio. Although
the principal amount of such borrowings will be fixed, the Portfolio's assets
may change in value during the time the borrowing is outstanding. By leveraging
the Portfolio, changes in net asset values,
    
 
                               Prospectus Page 10
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
higher or lower, may be greater in degree than if leverage was not employed. To
the extent the income derived from the assets obtained with borrowed funds
exceeds the interest and other expenses that the Portfolio will have to pay, the
Portfolio's net income will be greater than if borrowing was not used.
Conversely, if the income from the assets obtained with borrowed funds is not
sufficient to cover the cost of borrowing, the net income of the Portfolio will
be less than if borrowing were not used, and therefore the amount available for
distribution to shareholders as dividends will be reduced. The Portfolio each
expects that some of its borrowings may be made on a secured basis.
    
 
   
In addition to the foregoing borrowings, the Portfolio may borrow money for
temporary or emergency purposes or payments in an amount not exceeding 5% of the
value of its total assets (not including the amount borrowed) provided that the
total amount borrowed by the Portfolio for any purpose does not exceed 33 1/3%
of its total assets.
    
 
   
The Portfolio may also enter into reverse repurchase agreements with a bank or
recognized securities dealer. Under a reverse repurchase agreement, the
Portfolio would sell securities and agree to repurchase them at a particular
price at a future date. At the time the Portfolio enters into a reverse
repurchase agreement, it will establish and maintain a segregated account with
an approved custodian containing cash or liquid securities having a value not
less than the repurchase price, including accrued interest. Reverse repurchase
agreements involve the risk that the market value of the securities retained in
lieu of sale by the Portfolio may decline below the price of the securities the
Portfolio has sold but is obligated to repurchase. In the event the buyer of
securities under a reverse repurchase agreement files for bankruptcy or becomes
insolvent, such buyer or its trustee or receiver may receive an extension of
time to determine whether to enforce the Portfolio's obligation to repurchase
the securities, and the Portfolio's use of the proceeds of the reverse
repurchase agreement may effectively be restricted pending such decision.
    
 
   
The Portfolio also may enter into "dollar rolls," in which the Portfolio sells
fixed income securities for delivery in the current month and simultaneously
contracts to repurchase substantially similar (same type, coupon and maturity)
securities on a specified future date. During the roll period, the Portfolio
would forego principal and interest paid on such securities. The Portfolio would
be compensated by the difference between the current sales price and the forward
price for the future purchase, as well as by the interest earned on the cash
proceeds of the initial sale. See "Investment Objectives and Policies" in the
Statement of Additional Information.
    
 
   
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Portfolio's assets for purposes of calculating
compliance with the Portfolio's borrowing limitation. See "Investment
Limitations" in the Statement of Additional Information.
    
 
   
SECURITIES LENDING. The Portfolio may lend its respective portfolio securities
to broker/dealers or to other institutional investors. Securities lending allows
a Fund to retain ownership of the securities loaned and, at the same time,
enhances a Fund's total return. At all times a loan is outstanding, the
Portfolio requires the borrower to maintain with the Portfolio's custodian,
collateral consisting of cash, U.S. government securities, or certain
irrevocable letters of credit equal to at least the value of the borrowed
securities, plus any accrued interest or such other collateral as permitted by a
Fund's investment program and regulatory agencies, and as approved by the Board.
The Portfolio limits its loans of portfolio securities to an aggregate of 30% of
the value of its total assets, measured at the time any such loan is made. The
risks in lending portfolio securities, as with other extensions of secured
credit, consist of possible delays in receiving additional collateral or in
recovery of the loaned securities and possible loss of rights in the collateral
should the borrower fail financially.
    
 
   
ZERO COUPON SECURITIES. The Portfolio may invest in certain zero coupon
securities that are "stripped" U.S. Treasury notes and bonds. They also may
invest in zero coupon and other deep discount securities issued by foreign
governments and domestic and foreign corporations, including certain Brady Bonds
and other foreign debt and in payment-in-kind securities. Zero coupon securities
pay no interest to holders prior to maturity, and payment-in-kind securities pay
interest in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the "interest" on
payment-in-kind securities will be included in the Portfolio's income.
Accordingly, for a Fund to continue to qualify for tax treatment as a regulated
investment company and to avoid a certain excise tax (see "Taxes" in the
Statement of Additional Information), it may be required to distribute an amount
that is greater than its share of the total amount of cash the Portfolio
actually receives. These distributions must be made from the Fund's, or its
    
 
                               Prospectus Page 11
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
share of the Portfolio's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Portfolio will not be able to purchase
additional income-producing securities with cash used to make such
distributions, and its current income ultimately may be reduced as a result.
Zero coupon and payment-in-kind securities usually trade at a deep discount from
their face or par value and will be subject to greater fluctuations of market
value in response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
SYNTHETIC SECURITY POSITIONS. The Portfolio may utilize combinations of futures
on bonds and forward currency contracts to create investment positions that have
substantially the same characteristics as bonds of the same type as those on
which the futures contracts are written. Investment positions of this type are
generally referred to as "synthetic securities."
    
 
   
For example, in order to establish a synthetic security position the Portfolio
that is comparable to owning a Japanese government bond, the Sub-adviser might
purchase futures contracts on Japanese government bonds in the desired principal
amount and purchase forward currency contracts for Japanese Yen in an amount
equal to the then current purchase price for such bonds in the Japanese cash
market, with each contract having approximately the same delivery date.
    
 
   
The Sub-adviser might roll over the futures and forward currency contract
positions before taking delivery in order to continue the Portfolio's investment
position, or the Sub-adviser might close out those positions, thus effectively
selling the synthetic security. Further, the amount of each contract might be
adjusted in response to market conditions and the forward currency contract
might be changed in amount or eliminated in order to hedge against currency
fluctuations.
    
 
   
The Sub-adviser would create synthetic security positions for the Portfolio when
it believes that it can obtain a better yield or achieve cost savings in
comparison to purchasing actual bonds or when comparable bonds are not readily
available in the market. Synthetic security positions are subject to the risk
that changes in the value of purchased futures contracts may differ from changes
in the value of the bonds that might otherwise have been purchased in the cash
market. Also, while the Sub-adviser believes that the cost of creating synthetic
security positions generally will be materially lower than the cost of acquiring
comparable bonds in the cash market, the Portfolio will incur transaction costs
in connection with each purchase of a futures or forward currency contract. The
use of futures contracts and forward currency contracts to create synthetic
security positions also is subject to substantially the same risks as those that
exist when these instruments are used in connection with hedging strategies. See
"Options, Futures and Forward Currency Transactions" below and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies, and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the Portfolio's investment. The Portfolio also may enter into
interest rate, currency and index swaps and purchase or sell related caps,
floors and collars and other similar instruments. See "Swaps, Caps, Floors and
Collars" below. These instruments are often referred to as "derivatives," which
may be defined as financial instruments whose performance is derived, at least
in part, from the performance of another asset (such as a security, currency or
an index of securities). The Portfolio may enter into such instruments up to the
full value of its portfolio assets. See "Risk Factors -- Options, Futures and
Forward Currency Transactions" herein and "Options, Futures and Currency
Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to the Portfolio's portfolio positions. The Portfolio also may purchase
and sell put and call options on currencies, futures contracts on currencies and
options on such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on
securities to hedge against the risk of fluctuations in the prices of securities
held by the Portfolio or that the Sub-adviser intends to include in the
Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on
    
 
                               Prospectus Page 12
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
indices to hedge against overall fluctuations in the securities markets
generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general market or market sector decline that could adversely affect the
Portfolio's holdings. The Portfolio also may purchase index futures contracts
and purchase call options or write put options on such contracts to hedge
against a general market or market sector advance and thereby attempt to lessen
the cost of future securities acquisitions. The Portfolio may use interest rate
futures contracts and options thereon to hedge its portfolio against changes in
the general level of interest rates.
    
 
   
SWAPS, CAPS, FLOORS AND COLLARS. The Portfolio may enter into interest rate,
currency and index swaps, and purchase or sell related caps, floors and collars
and other derivative instruments. The Portfolio expects to enter into these
transactions primarily to preserve a return or spread on a particular investment
or portion of its portfolio, to protect against currency fluctuations, as a
technique for managing the portfolio's duration (I.E., the price sensitivity to
changes in interest rates) or to protect against any increase in the price of
securities the Portfolio anticipates purchasing at a later date. The Portfolio
intends to use these transactions as hedges, and neither will sell interest rate
caps or floors if it does not own securities or other instruments providing an
income stream roughly equivalent to what the Portfolio may be obligated to pay.
    
 
   
Interest rate swaps involve the exchange by the Portfolio with another party of
their respective commitments to pay or receive interest (for example, an
exchange of floating rate payments for fixed rate payments) with respect to a
notional amount of principal. A currency swap is an agreement to exchange cash
flows on a notional amount based on changes in the values of the reference
indices.
    
 
   
The purchase of a cap entitles the purchaser to receive payments on a notional
principal amount from the party selling the cap to the extent that a specified
index exceeds a predetermined interest rate. The purchase of an interest rate
floor entitles the purchaser to receive payments on a notional principal amount
from the party selling the floor to the extent that a specified index falls
below a predetermined interest rate or amount. A collar is a combination of a
cap and a floor that preserves a certain return within a predetermined range of
interest rates or values.
    
 
   
INDEXED COMMERCIAL PAPER. The Portfolio may invest without limitation in
commercial paper which is indexed to certain specific foreign currency exchange
rates. The terms of such commercial paper provide that its principal amount is
adjusted upwards or downwards (but not below zero) at maturity to reflect
changes in the exchange rate between two currencies while the obligation is
outstanding. The Portfolio will purchase such commercial paper with the currency
in which it is denominated and, at maturity, will receive interest and principal
payments thereon in that currency, but the amount of principal payable by the
issuer at maturity will change in proportion to the change (if any) in the
exchange rate between the two specified currencies between the date the
instrument is issued and the date the instrument matures. While such commercial
paper entails the risk of loss of principal, the potential for realizing gains
as a result of changes in foreign currency exchange rates enables the Portfolio
to hedge against a decline in the U.S. dollar value of investments denominated
in foreign currencies while seeking to provide an attractive money market rate
of return. The Portfolio will not purchase such commercial paper for
speculation.
    
 
   
OTHER INDEXED SECURITIES. The Portfolio may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of other
securities, securities indices, currencies, precious metals or other
commodities, or other financial indicators. Indexed securities typically, but
not always, are debt securities or deposits whose value at maturity or coupon
rate is determined by reference to a specific instrument or statistic. The
performance of indexed securities depends to a great extent on the performance
of the security, currency, or other instrument to which they are indexed, and
may also be influenced by interest rate changes in the United States and abroad.
At the same time, indexed securities are subject to the credit risks associated
with the issuer of the security, and their values may decline substantially if
the issuer's creditworthiness deteriorates. Indexed securities may be more
volatile than the underlying instruments. New forms of indexed securities
continue to be developed. The Portfolio may invest in such securities to the
extent consistent with its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a
    
 
                               Prospectus Page 13
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
majority of the Fund's outstanding voting securities. A "majority of the Fund's
outstanding voting securities" means the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented, or (ii) more than 50% of the outstanding shares. In addition, the
Fund has adopted certain investment limitations which also may not be changed
without shareholder approval. A complete description of these limitations is
included in the Statement of Additional Information. Unless specifically noted,
the Fund's investment policies described in this Prospectus and in the Statement
of Additional Information are not fundamental policies and may be changed by the
Trust's Board of Trustees without shareholder approval. The investment policies
of the Fund are identical to the investment policies of the Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objectives, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objectives.
    
 
   
The Fund is authorized to make short sales of securities, although it has no
current intention of doing so. See "Investment Objectives and Policies -- Short
Sales" in the Statement of Additional Information.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Portfolio's investment policies or restrictions.
    
 
- --------------------------------------------------------------------------------
 
   
                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objectives. The Portfolio's net asset value will fluctuate,
reflecting fluctuations in the market value of its portfolio positions and its
net currency exposure. The value of fixed income securities held by the
Portfolio generally fluctuates inversely with interest rate movements. Longer
term bonds held by the Portfolio are subject to greater interest rate risk.
    
   
NON-DIVERSIFIED CLASSIFICATION. The Fund and the Portfolio are classified under
the Investment Company Act of 1940 (the "1940 Act") as a "non-diversified" fund.
As a result, the Portfolio will be able to invest in a fewer number of issuers
than if it were classified under the 1940 Act as a "diversified" fund. To the
extent that the Portfolio invests in a smaller number of issuers, the value of
the Fund's shares may fluctuate more widely and the Portfolio may be subject to
greater investment and credit risk with respect to the portfolios.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies. In addition, certain costs
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Portfolio's interest and dividends from
foreign issuers may be subject to non-U.S. withholding taxes, thereby reducing
their net investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the investments of the Portfolio in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, rate of savings and
    
 
                               Prospectus Page 14
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
capital reinvestment, resource self-sufficiency and balance of payments
positions.
    
 
   
CURRENCY RISK. Since the Portfolio normally invests substantially in securities
denominated in currencies other than the U.S. dollar, and because they may hold
foreign currencies, they will be affected favorably or unfavorably by exchange
control regulations or changes in the exchange rates between such currencies and
the U.S. dollar. Changes in currency exchange rates will influence the value of
the Fund's shares, and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by the Fund. Currencies
generally are evaluated on the basis of fundamental economic criteria (e.g.,
relative inflation and interest rate levels and trends, growth rate forecasts,
balance of payments status and economic policies) as well as technical and
political data. The exchange rates between the U.S. dollar and other currencies
are determined by supply and demand in the currency exchange markets, the
international balance of payments, governmental intervention, speculation and
other economic and political conditions. If the currency in which a security is
denominated appreciates against the U.S. dollar, the dollar value of the
security will increase. Conversely, a decline in the exchange rate of the
currency would adversely affect the value of the security expressed in U.S.
dollars.
    
 
   
In addition, many of the currencies in emerging market countries have
experienced steady devaluations relative to the U.S. dollar and major
devaluations have historically occurred in certain countries.
    
 
   
INVESTING IN EMERGING MARKETS. Because of the special risks associated with
investing in emerging markets, an investment in the Portfolio should be
considered speculative. Investors are strongly advised to consider carefully the
special risks involved in emerging markets, which are in addition to the usual
risks of investing in developed foreign markets around the world.
    
 
   
Investing in emerging markets involves risks relating to potential political and
economic instability within such markets and the risks of expropriation,
nationalization, confiscation of assets and property or the imposition of
restrictions on foreign investment and on repatriation of capital invested. In
the event of such expropriation, nationalization or other confiscation in any
emerging market, the Portfolio could lose its entire investment in that market.
    
 
   
Many emerging market countries have experienced substantial, and in some periods
extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain emerging market
countries.
    
 
   
Economies in emerging markets generally are dependent heavily upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values and other protectionist measures imposed or negotiated by the countries
with which they trade. These economies also have been and may continue to be
affected adversely by economic conditions in the countries in which they trade.
    
 
   
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
United States and other more developed countries. Disclosure and regulatory
standards in many respects are less stringent than in the United States and
other major markets. There also may be a lower level of monitoring and
regulation of emerging securities markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
    
 
   
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Portfolio to make intended securities purchases due to
settlement problems could cause the Portfolio to forego attractive investment
opportunities. Inability to dispose of a portfolio security caused by settlement
problems could result either in losses to the Portfolio due to subsequent
declines in value of the portfolio security or, if the Portfolio has entered
into a contract to sell the security, could result in possible liability to the
purchaser.
    
 
   
The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading of securities may cease or may be
substantially curtailed and prices for the Portfolio's portfolio securities in
such markets may not be readily available. Section 22(e) of the 1940 Act
    
 
                               Prospectus Page 15
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
permits a registered investment company to suspend redemption of its shares for
any period during which an emergency exists, as determined by the SEC.
Accordingly, when the Portfolio believes that appropriate circumstances warrant,
it will promptly apply to the SEC for a determination that an emergency exists
within the meaning of Section 22(e) of the 1940 Act. During the period
commencing from the Portfolio's identification of such conditions until the date
of SEC action, the portfolio securities of the Portfolio in the affected markets
will be valued at fair value as determined in good faith by or under the
direction of the Trust's or the Portfolio's Boards of Trustees.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Portfolio may have difficulty disposing
of Assignments and Participations. The liquidity of such securities is limited
and the Portfolio anticipates that such securities could be sold only to a
limited number of institutional investors. The lack of a liquid secondary market
could have an adverse impact on the value of such securities and on the
Portfolio's ability to dispose of particular Assignments or Participations when
necessary to meet the Portfolio's liquidity needs or in response to a specific
economic event, such as a deterioration in the creditworthiness of the borrower.
The lack of a liquid secondary market for Assignments and Participations also
may make it more difficult for the Portfolio to assign a value to those
securities for purposes of valuing the Portfolio's portfolio and calculating its
net asset value.
    
 
   
SOVEREIGN DEBT. The Portfolio may invest in sovereign debt securities of
emerging market governments, including Brady Bonds. Investments in such
securities involve special risks. The issuer of the debt or the governmental
authorities that control the repayment of the debt may be unable or unwilling to
repay principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn a Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
   
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
    
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Portfolio's
investments. Emerging markets are faced with social and political issues and
some of them have experienced high rates of inflation in recent years and have
extensive internal debt. Among other effects, high inflation and internal debt
service requirements may adversely affect the cost and availability of future
domestic sovereign borrowing to finance governmental programs, and may have
other adverse social, political and economic consequences. Political changes or
a deterioration of a country's domestic economy or balance of trade may affect
the willingness of countries to service their sovereign debt. Although the
Sub-adviser intends to manage the Portfolio in a manner that will minimize the
exposure to such risks, there can be no assurance that adverse political changes
will not cause the Portfolio to suffer a loss of interest or principal on any of
its holdings.
    
 
   
In recent years, some of the emerging market countries in which the Portfolio
expects to invest have encountered difficulties in servicing their sovereign
debt obligations. Some of these countries have withheld payments of interest
and/or principal of sovereign debt. These difficulties have also led to
agreements to restructure external debt obligations -- in particular, commercial
bank loans, typically by rescheduling principal payments, reducing interest
rates and extending new credits to finance interest payments on existing debt.
In the future, holders of emerging market sovereign debt securities may be
requested to participate in similar rescheduling of such debt. Certain
    
 
                               Prospectus Page 16
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
emerging market countries are among the largest debtors to commercial banks and
foreign governments. Currently, Brazil, Mexico and Argentina are the largest
debtors among developing countries. At times certain emerging market countries
have declared moratoria on the payment of principal and interest on external
debt; such a moratorium is currently in effect in certain emerging market
countries. There is no bankruptcy proceeding by which a creditor may collect in
whole or in part sovereign debt on which an emerging market government has
defaulted.
    
 
   
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
    
 
   
Investors should also be aware that certain sovereign debt instruments in which
the Portfolio may invest involve great risk. As noted above, sovereign debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to securities rated below investment grade by
Moody's and S&P. Such securities are regarded as predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligations and involve major risk exposure to
adverse conditions. Some of such securities, with respect to which the issuer
currently may not be paying interest or may be in payment default, may be
comparable to securities rated D by S&P or C by Moody's. The Portfolio may have
difficulty disposing of and valuing certain sovereign debt obligations because
there may be a limited trading market for such securities. Because there is no
liquid secondary market for many of these securities, the Portfolio anticipates
that such securities could be sold only to a limited number of dealers or
institutional investors.
    
 
   
LOWER QUALITY DEBT SECURITIES. Under normal market conditions the Portfolio may
invest up to 100% of the Portfolio's total assets in debt securities rated below
investment grade. Such investments involve a high degree of risk.
    
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest quality debt that is not in default as to
principal or interest and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than higher quality securities with regard to a deterioration of general
economic conditions. These securities are the equivalent of high yield, high
risk bonds, commonly known as "junk bonds." As noted above, the Portfolio may
invest in debt securities rated below C, which are in default as to principal
and/or interest.
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit quality in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Appendix A" for a discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability
    
 
                               Prospectus Page 17
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
   
to service its debt obligations may also be adversely affected by specific
developments affecting the issuer, such as the issuer's inability to meet
specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because there may be a thin trading market for such securities. There
may be no established retail secondary market for many of these securities, and
the Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing the securities in the Portfolio. Adverse
publicity and investor perceptions, whether or not based on fundamental
analysis, may also decrease the values and liquidity of lower quality
securities, especially in a thinly traded market. The Portfolio also may acquire
lower quality debt securities during an initial underwriting or may acquire
lower quality debt securities which are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
Factors having an adverse effect on the market value of lower rated securities
or their equivalents purchased by the Portfolio will adversely impact net asset
value of the Fund. See "Risk Factors" in the Statement of Additional
Information. In addition to the foregoing, such factors may include: (i)
potential adverse publicity; (ii) heightened sensitivity to general economic or
political conditions; and (iii) the likely adverse impact of a major economic
recession. The Portfolio also may incur additional expenses to the extent it is
required to seek recovery upon a default in the payment of principal or interest
on its portfolio holdings, and the Portfolio may have limited legal recourse in
the event of a default. Debt securities issued by governments in emerging
markets can differ from debt obligations issued by private entities in that
remedies from defaults generally must be pursued in the courts of the defaulting
government, and legal recourse is therefore somewhat diminished. Political
conditions, in terms of a government's willingness to meet the terms of its debt
obligations, also are of considerable significance. There can be no assurance
that the holders of commercial bank debt may not contest payments to the holders
of debt securities issued by governments in emerging markets in the event of
default by the governments under commercial bank loan agreements.
    
 
   
As of October 31, 1997, the Portfolio had 86.59% of its total net assets in debt
securities that received a rating from Moody's and 10.29% of its total net
assets in debt securities that were not so rated. In addition, the Portfolio had
3.12%, of its total net assets in cash and net receivables. The Portfolio had
the following percentages of its total net assets invested in rated securities:
Aaa -- 7.99%, Aa -- 0.00%, A -- 0.00%, Baa -- 13.11%, Ba -- 48.56%, B -- 16.93%,
Caa -- 0.00%, Ca -- 0.00%, C -- 0.00%. Included under the unrated category are
securities held by the Portfolio's total net assets which have been determined
by the Sub-adviser to be of comparable quality to securities in the following
rating categories: Ba -- 3.22%; and B -- 7.07%. It should be noted that the
allocation of the investments of the Portfolio by rating on any given date will
vary and should not be considered representative of the future portfolio
composition of the Portfolio.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. In addition, issuers in
emerging markets typically are subject to a greater degree of change in earnings
and business prospects than issuers in developed countries. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed
    
 
                               Prospectus Page 18

                          AIM GLOBAL HIGH INCOME FUND
   
to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Portfolio invests; (4) lack of assurance that a liquid secondary
market will exist for any particular option, futures contract or option thereon
at any particular time; (5) the possible loss of principal under certain
conditions; and (6) the possible inability of the Portfolio to purchase or sell
a portfolio security at a time when it would otherwise be favorable for it to do
so, or the possible need for the Portfolio to sell a security at a
disadvantageous time, due to the need for the Portfolio to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets, in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.

The Trust's and the Portfolio's Boards of Trustees have overall responsibility
for the operation of the Fund and the Portfolio, respectively. The Trust's and
Portfolio's Boards of Trustees have approved all significant agreements between
the Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the objective and policies of the Fund and the
Portfolio and to the general supervision of the Boards. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's and the Portfolio's Trustees.
    
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Portfolio's investment managers and administrators include,
but are not limited to, determining the composition of the investment holdings
of the Portfolio and placing orders to buy, sell or hold particular securities.
In addition, AIM and the Sub-adviser provide the following administration
services to the Fund and the Portfolio: furnishing corporate officers and
clerical staff; providing office space, services and equipment; and supervising
all matters relating to the Portfolio's operation.
    
 
   
The Fund pays AIM administration fees at the annualized rate of 0.25% of the
Fund's average daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by the Portfolio to AIM and
the Sub-adviser. The Portfolio pays AIM such fees, based on the average daily
net assets of the Portfolio at the annualized rate of .475% on the first $500
million, .45% on the next $1 billion, .425% on the next $1 billion and .40% on
amounts thereafter, plus 2% of the Portfolio's total investment income as stated
in the Portfolio's Statement of Operations, calculated in accordance with
generally accepted accounting principles, adjusted daily for currency
revaluations, on a marked to market basis, of the Portfolio's assets; provided,
however, that during any fiscal year this amount shall not exceed 2% of the
Portfolio's total investment income calculated in accordance with generally
accepted accounting principles. Out of its aggregate fees payable by the Fund
and the Portfolio, AIM pays the Sub-adviser sub-advisory and sub-administration
fees equal to 40% of the aggregate fees AIM receives from the Fund and the
Portfolio. The investment management and administration fees paid by the Fund
and the Portfolio are higher than those paid by most mutual funds. The Fund and
Portfolio pay all expenses not

assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit the expenses of the Advisor Class shares of the Fund (and
the Fund's pro-rata portion of the Portfolio's expenses) to the maximum annual
rate of 1.85% of the average daily net assets of the Fund's Advisor Class
shares.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund and the Portfolio, the Sub-adviser employs a
team approach, taking advantage of its investment resources around the world.

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions for the Portfolio may be
executed through affiliates of AIM or the Sub-adviser. High portfolio turnover
(over 100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund or the Portfolio will bear directly and could
result in the realization of net capital gains which would be taxable when
distributed to shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust.
    
 
   
From time to time, the Trust may establish other funds, each corresponding to a
distinct investment portfolio and a distinct series of the Trust's shares of
beneficial interest. Shares of each fund are entitled to one vote per share
(with proportional voting for fractional shares) and are freely transferable.
Shareholders have no preemptive rights. Other than the automatic conversion of
Class B shares to Class A shares, there are no conversion rights.

On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a Delaware business
trust. Under Delaware law, the Fund and other entities that invest in the
Portfolio enjoy the same limitations of liability extended to shareholders of
private, for-profit corporations. There is a remote possibility, however, that
under certain circumstances an investor in the Portfolio may be held liable for
the Portfolio's obligations. However, the Agreement and Declaration of Trust of
the Portfolio disclaims shareholder liability for acts or obligations of the
Portfolio and requires that notice of such disclaimer be given in each
agreement, obligation or instrument entered into or executed by the Portfolio or
a trustee. The Agreement and Declaration of Trust also provides for
indemnification from the Portfolio property for all losses and expenses of any
shareholder held personally liable for the Portfolio's obligations. Thus the
risk of an investor incurring financial loss on account of such liability is
limited to circumstances in which the Portfolio itself would be unable to meet
its obligations and where the other party was held not to be bound by the
disclaimer.
    
 
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of Fund shareholders and will cast its vote as
instructed by Fund shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

                                   APPENDIX A
                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from "Aaa" to "C." Investment grade ratings are the first
four categories:
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered as well-assured. Often the protection of
    interest and principal payments may be very moderate, and thereby not well
    safeguarded during both good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B -- Bonds which are rated B generally lack characteristics of the
    desirable investment. Assurance of interest and principal payments or of
    maintenance of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa are of poor standing. Such issues may
    be in default or there may be present elements of danger with respect to
    principal or interest.
 
        Ca -- Bonds which are rated Ca represent obligations which are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are rated C are the lowest rated class of bonds, and
    issues so rated can be regarded as having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.
 
                               Prospectus Page 23
<PAGE>
                          AIM GLOBAL HIGH INCOME FUND
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various entities in categories ranging from "AAA"
to "D" according to quality. Investment grade ratings are the first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations rated "BB," "B," "CCC," "CC," and "C"
    are regarded as having significant speculative characteristics. "BB"
    indicates the least degree of speculation and "C" the highest. While such
    obligations will likely have some quality and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An obligation rated "BB" is less vulnerable to nonpayment than
    other speculative issues. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate capacity to meet its financial commitment
    on the obligation.
 
        B -- An obligation rated "B" is more vulnerable to nonpayment than
    obligations rated "BB," but the obligor currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its financial commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to have the capacity to meet its financial commitment on the
    obligation.
 
        CC -- An obligation rated "CC" is currently highly vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed or similar action has been taken, but payments on
    this obligation are being continued.
 
        D -- An obligation rated "D" is in payment default. The "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the applicable grace period has not expired, unless S&P believes
    that such payments will be made during such grace period. The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally will be evidenced by many of
the characteristics cited above but to a lesser degree. Earnings trends and
coverage ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is

<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in

<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.

Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                               Advisor Class shares of any of the other funds in The AIM Family of Funds that are sub-advised
                               by the Sub-adviser ("AIM Funds") on May 29, 1998; (e) any of the companies composing or
                               affiliated with AMVESCAP PLC; and (f) AIM Global Trends Fund. Pursuant to a separate
                               prospectus, the Fund also offers Class A and Class B shares, which represent interests in the
                               Fund. The Class A and Class B shares have different distribution arrangements.
 
                               Initial investments in Advisor Class shares must be at least $500 and additional investments
                               must be at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc.
                               ("AIM Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."

Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at the
                               Fund's net asset value on any business day. See "How to Redeem Shares."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis.
                               Dividends and distributions of the Fund may be reinvested at net asset value without payment of
                               a sales charge in the Fund's shares or may be invested in shares of the other funds in The AIM
                               Family of Funds. See "Dividends, Distributions and Tax Matters."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve its investment objective. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the
                               Portfolio's portfolio holdings. The Portfolio's policy of concentrating its investments in
                               companies that design, develop or provide products and services significant to a country's
                               infrastructure may cause the Fund's net asset value to fluctuate more than if it invested in a
                               greater number of industries.
 
                               The Portfolio may invest in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the
                               regulations to which U.S. and foreign issuers are subject. Individual foreign economies also
                               may differ favorably or unfavorably from the U.S. economy. Changes in foreign currency ex-
                               change rates will affect the Fund's net asset value, earnings and gains and losses realized on
                               sales of securities. Securities of foreign companies may be less liquid and their prices more
                               volatile than those of securities of comparable U.S. companies.
 
                               The Portfolio may engage in certain foreign currency, options and futures transactions to
                               attempt to hedge against the overall level of investment and currency risk associated with its
                               present or planned investments. Such transactions involve certain risks and transaction costs.

                               The Portfolio may invest up to 20%, of its total assets in below investment grade debt
                               securities. Investments of this type are subject to a greater risk of loss of principal and

- --------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUNDS.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 1.50% of the average daily net assets of each Fund's Advisor
    Class shares. Without reimbursements, "Other Expenses" and "Total Fund
    Operating Expenses" would have been 0.60% and 1.58%, respectively, for
    Advisor Class shares of the Infrastructure Fund. "Other expenses" include
    custody, transfer agency, legal, audit and other operating expenses. See
    "Management" herein and the Statement of Additional Information for more
    information. Investors purchasing Advisor Class shares through financial
    planners, trust companies, bank trust departments or registered investment
    advisers, or under a "wrap fee" program, will be subject to additional fees
    charged by such entities or by the sponsors of such programs. Where any
    account advised by one of the companies composing or affiliated with
    AMVESCAP PLC invests in Advisor Class shares of the Fund, such account shall
    not be subject to duplicative advisory fees.
    
 
   
    The Board of Trustees of the Trust believes that the aggregate per share
    expenses of the Infrastructure Fund and its corresponding Portfolio will be
    approximately equal to the expenses the Fund would incur if its assets were
    invested directly in the type of securities being held by its Portfolio.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds. The 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.

The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
                         AIM GLOBAL INFRASTRUCTURE FUND

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
INFRASTRUCTURE FUND
    
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that design, develop or provide products and services significant to a country's
infrastructure. The Portfolio's investment objective is identical to that of the
Fund. There can be no assurance that the Fund or Portfolio will achieve its
investment objective.
    
 
   
At least 65% of the Portfolio's total assets normally will be invested in common
and preferred stocks and warrants to acquire such securities issued by
infrastructure companies. An "infrastructure" company is an entity in which (i)
at least 50% of either the revenues or earnings was derived from infrastructure
activities, or (ii) at least 50% of the assets was devoted to such activities,
based on the company's most recent fiscal year. The remainder of the Portfolio's
assets may be invested in debt securities issued by infrastructure companies
and/or equity and debt securities of companies outside of the infrastructure
industries, which, in the opinion of the Sub-adviser, stand to benefit from
developments in the infrastructure industries.
    
 
   
GLOBAL INFRASTRUCTURE INDUSTRIES INVESTMENT. Examples of infrastructure
companies include those engaged in designing, developing or providing the
following products and services: electricity production; oil, gas, and coal
exploration, development, production and distribution; water supply, including
water treatment facilities; nuclear power and other alternative energy sources;
transportation, including the construction or operation of transportation
systems; steel, concrete, or similar types of products; communications equipment
and services (including equipment and services for both data and voice
transmission); mobile communications and cellular radio/paging; emerging
technologies combining telephone, television and/or computer systems; and other
products and services, which, in the Sub-adviser's judgment, constitute services
significant to the development of a country's infrastructure.
    
 
   
The Sub-adviser believes that a country's infrastructure is one key to the
long-term success of that country's economy. The Sub-adviser believes that
adequate energy, transportation, water, and communications systems are essential
elements for long-term economic growth. The Sub-adviser believes that many
developing nations, especially in Asia and Latin America, plan to make
significant expenditures to the development of their infrastructure in the
coming years, which is expected to facilitate increased levels of services and
manufactured goods.
    
 
   
In the developed countries of North America, Europe, Japan and the Pacific Rim,
the Sub-adviser expects that the replacement and upgrade of transportation and
communications systems should stimulate growth in the infrastructure industries
of those countries. In addition, in the Sub-adviser's view, deregulation of
telecommunications and electric and gas utilities in many countries is promoting
significant changes in these industries.
    
 
   
The Sub-adviser believes that strong economic growth in developing countries and
infrastructure replacement, upgrade, and deregulation in more developed
countries provide an environment for favorable investment opportunities in
infrastructure companies worldwide. In addition, the long-term growth rates of
certain foreign countries' economies may be substantially higher than the
long-term growth rate of the U.S. economy. An integral aspect of certain foreign
countries' economies may be the development or improvement of their
infrastructure.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the
infrastructure industries are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets
    
 
                               Prospectus Page 6
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
located throughout the world and the substantial global resources of AMVESCAP
PLC in attempting to identify those countries and companies then providing the
greatest potential for long-term capital appreciation. In this fashion, the
Sub-adviser seeks to enable shareholders to capitalize on the substantial
investment opportunities and the potential for long-term growth of capital
presented by the global infrastructure industry represented in the Portfolio.
    
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 50% of the Portfolio's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Fund's shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.
    
 
                               Prospectus Page 7
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Portfolio's sale of securities together with
its commitment (for which the Portfolio may receive a fee) to purchase similar,
but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolio to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other collateral as permitted by the Portfolio's investment program and
regulatory agencies, and as approved by the Board. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write
    
 
                               Prospectus Page 8
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
call options on such futures contracts to protect against a general stock market
decline or a decline in a specific market sector that could affect adversely the
Portfolio's holdings. The Portfolio also may purchase stock index futures
contracts and purchase call options or write put options on such contracts to
hedge against a general stock market or market sector advance and thereby
attempt to lessen the cost of future securities acquisitions. The Portfolio may
use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval. The investment policies of the Fund are identical to the
investment policies of the Portfolio.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts," respectively in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because the Fund will invest only in the Portfolio, the Fund's shareholders will
acquire only an indirect interest in the investments of the Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as
    
 
                               Prospectus Page 9

                         AIM GLOBAL INFRASTRUCTURE FUND
   
the Fund and may charge different sales commissions. Therefore, investors in the
Fund may experience different returns than investors in another investment
company that invests exclusively in the Portfolio. As of the date of this
Prospectus, the Fund is the only institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities positions. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the infrastructure industries,
an investment in it may be more volatile than that of other investment companies
that do not concentrate their investments in such a manner. Moreover, the value
of the shares of the Fund will be especially susceptible to factors affecting
the infrastructure industries. Accordingly, the Fund should be considered a
complete investment program.
    
 
   
INFRASTRUCTURE INDUSTRIES. Infrastructure industries may be subject to greater
political, environmental and other governmental regulation than many other
industries. The nature of such regulation continues to evolve in both the United
States and foreign countries, and changes in governmental policy and the need
for regulatory approvals may have a material effect on the products and services
offered by companies in the infrastructure industries. Electric, gas, water and
most telecommunications companies in the United States, for example, are subject
to both federal and state regulation affecting permitted rates of return and the
kinds of services that may be offered. Governmental regulation may also hamper
the development of new technologies.
    
 
   
In addition, many infrastructure companies have historically been subject to the
risks attendant to increases in fuel and other operating costs, high interest
costs on borrowed funds, costs associated with compliance with environmental and
other safety regulations and changes in the regulatory climate. Further,
competition is intense for many infrastructure companies. As a result, many of
these companies may be adversely affected in the future and such companies may
be subject to increased share price volatility. In addition, many companies have
diversified into oil and gas exploration and development, and therefore returns
may be more sensitive to energy prices. Other infrastructure companies, such as
water supply companies, are in a highly fragmented industry due to local
ownership. Generally these companies are mature and are experiencing little or
no growth. Changes in prevailing interest rates may also affect the
Infrastructure Fund's share values because prices of equity and debt securities
of infrastructure companies often tend to increase when interest rates decline
and decrease when interest rates rise.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less
    
 
                               Prospectus Page 10
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
publicly available information about foreign securities and issuers than is
available about domestic securities and issuers. Foreign companies generally are
not subject to uniform accounting, auditing and financial reporting standards,
practices and requirements comparable to those applicable to domestic companies.
In addition, certain costs attributable to foreign investing, such as custody
charges, are higher than those attributable to domestic investing. Securities of
some foreign companies are less liquid and their prices may be more volatile
than securities of comparable domestic companies. The Portfolio's interest and
dividends from foreign issuers may be subject to non-U.S. withholding taxes,
thereby reducing the Portfolio's net investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 20%, of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition,
    
 
                               Prospectus Page 11
<PAGE>
                         AIM GLOBAL INFRASTRUCTURE FUND
   
lower quality debt securities tend to be more sensitive to economic conditions
and generally have more volatile prices than higher quality securities. Issuers
of lower quality securities are often highly leveraged and may not have
available to them more traditional methods of financing. For example, during an
economic downturn or a sustained period of rising interest rates, highly
leveraged issuers of lower quality securities may experience financial stress.
During such periods, such issuers may not have sufficient revenues to meet their
interest payment obligations. The issuer's ability to service its debt
obligations may also be adversely affected by specific developments affecting
the issuer, such as the issuer's inability to meet specific projected business
forecasts or the unavailability of additional financing. The risk of loss due to
default by the issuer is significantly greater for the holders of lower quality
securities because such securities are generally unsecured and may be
subordinated to the claims of other creditors of the issuer.
    
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if it did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
   
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the Portfolio to sell a security at a disadvantageous time, due to the need for
the Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.

INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.
    
 
                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administration agreement with AIM, the investment sub-advisory
and sub-administration agreement between AIM and the Sub-adviser, the agreements
with AIM Distributors regarding distribution of the Fund's shares, the custody
agreement and the transfer agency agreement. The day-to-day operations of the
Fund and the Portfolio are delegated to the officers of the Trust and the
Portfolio, subject always to the investment objective and policies of the Fund
and the Portfolio and to the general supervision of the Boards. See "Trustees
and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers to the Fund and the Portfolio include,
but are not limited to, determining the composition of the investment portfolio
of the Portfolio and placing orders to buy, sell or hold particular securities.
In addition, AIM and the Sub-adviser provide the following administration
services to the Portfolio and the Fund: furnishing corporate officers and
clerical staff; providing office space, services and equipment; and supervising
all matters relating to the Portfolio's and the Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by its corresponding
Portfolio to AIM and the Sub-adviser. The Portfolio pays AIM a fee, based on the
Portfolio's average daily net assets at the annualized rate of .725% on the
first $500 million, .70% on the next $500 million, .675% on the next $500
million and .65% on all amounts thereafter. Out of its aggregate fees payable by
the Fund and Portfolio, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund and Portfolio. The investment management and administration fees paid by
the Fund and the Portfolio are higher than those paid by most mutual funds. The
Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors or
other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 1.50% of the average daily net assets of the Fund's Advisor Class
shares.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% to the first $5 billion of assets, and 0.02% to the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the
Portfolio, pays an amount based upon its relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administration services agreement,

dated as of May 29, 1998 (the "Advisory Agreement"). AIM was organized in 1976
and, together with its subsidiaries, manages or advises approximately 90
investment company portfolios encompassing a broad range of investment
objectives. The Sub-adviser, 50 California Street, 27th Floor, San Francisco,
California 94111, and 1166 Avenue of the Americas, New York, New York 10036,
serves as the sub-adviser to the Portfolio pursuant to an investment
sub-advisory and sub-administration agreement dated as of May 29, 1998. Prior to
May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset Management, Inc.
On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the former indirect
parent organization of the Sub-adviser, consummated a purchase agreement with
AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset Management
Division, which included the Sub-adviser and certain other affiliates. As a
result of this transaction, the Sub-adviser is now an indirect wholly owned
subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and its worldwide
asset management affiliates provided investment management and/or administrative
services to institutional, corporate and individual clients around the world
since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Funds will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Company acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series or
portfolios of the Trust. From time to time, the Company may establish other
funds, each corresponding to a distinct investment portfolio and a distinct
series of the Trust's shares of beneficial interest. Shares of each fund are
entitled to one vote per share (with proportional voting for fractional shares)
and are freely transferable. Shareholders have no preemptive rights. Other than
the automatic conversion of Class B shares to Class A shares, there are no
conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Company may
issue an unlimited number of shares of the Fund. Each share of the Fund
represents an interest in the Fund only, has a par value of $0.01 per share,
represents an equal proportionate interest in the Fund with other shares of the
Fund and is entitled to such dividends and distributions out of the income
earned and gain realized on the assets belonging to the Fund as may be declared
by the Board of Trustees. Each share of the Fund is equal in earnings, assets
and voting privileges except that each class normally has exclusive voting
rights with respect to its distribution plan and bears the expenses, if any,
related to the distribution of its shares. Shares of the Fund, when issued, are
fully paid and nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of the Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

sponsored by organizations that have at least 1,000 employees; (b) any account
with assets of at least $10,000 if (i) a financial planner, trust company, bank

the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is

                                      A-2
<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in

<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the

proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.

DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE

ADVISORS BEFORE INVESTING.
 
   
    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.
    
 
   
    AIM DEVELOPING MARKETS FUND, AIM EMERGING MARKETS FUND, AIM EUROPE GROWTH
FUND, AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND, AIM GLOBAL FINANCIAL
SERVICES FUND, AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HEALTH CARE FUND, AIM
GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

The Fund and the Portfolio:    The Fund is a diversified series of the Trust. The Portfolio is a diversified series of the
                               Portfolio.
 
Investment Objective:          The Fund seeks long-term capital growth.
 
Principle Investments:         The Fund invests all of its investable assets in the Portfolio, which, in turn, invests primarily in

                               its subsidiaries are an independent investment management group that has a significant presence in
                               the institutional and retail segment of the investment management industry in North America and

                               company, bank trust department or registered investment adviser has investment discretion over such
                               account, and (ii) the account holder pays such person as compensation for its advice and other

<TABLE>
<S>                            <C>                                               <C>
                               program, and (ii) the account holder pays the sponsor of such program an annual fee of at least 0.50%
                               on the assets in the account; (d) accounts advised by the Sub-adviser or one of the companies
                               formerly affiliated with the Asset Management Division of Liechtenstein Global Trust AG, provided
                               such accounts were invested in Advisor Class shares of any of the funds in The AIM Family of Funds
                               that are sub-advised by the Sub-adviser ("AIM Funds") on May 29, 1998; (e) any of the companies
                               composing or affiliated with AMVESCAP PLC; and (f) AIM Global Trends Fund. Pursuant to a separate
                               prospectus, the Fund also offers Class A and Class B shares, which represent interests in the Fund.
                               The Class A and Class B shares have different distribution arrangements.
 
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               funds in The AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."
 
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at the Fund's net
                               asset value on any business day. See "How to Redeem Shares."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
 
Risk Factors:                  There is no assurance that the Fund or the Portfolio will achieve its investment objective. The
                               Fund's net asset value will fluctuate, reflecting fluctuations in the market value of the Portfolio's
                               portfolio holdings. The Portfolio's policy of concentrating its investments in companies in the
                               natural resources industries may cause the Fund's net asset value to fluctuate more than if it
                               invested in a greater number of industries.
 
                               The Portfolio may invest in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.

                               The Portfolio may engage in certain foreign currency, options and futures transactions to attempt to
                               hedge against the overall level of investment and currency risk associated with its present or
                               planned investments. Such transactions involve certain risks and transaction costs.
 
                               The Portfolio may invest up to 20%, of its total assets in below investment grade debt securities.
                               Investments of this type are subject to a greater risk of loss of principal and interest.

- --------------
   
(1) THIS TABLE IS INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended October 31, 1997 restated
    to reflect AIM's undertaking to limit the Fund's expenses (exclusive of
    brokerage commissions, taxes, interest and extraordinary expenses) to the
    annual rate of 1.50% of the average daily net assets of the Fund's Advisor
    Class shares. Without reimbursements, "Other Expenses" and "Total Fund
    Operating Expenses" would have been 0.65% and 1.63%, respectively, for
    Advisor Class Shares of the Fund. "Other expenses" include custody, transfer
    agency, legal, audit and other operating expenses. See "Management" herein
    and the Statement of Additional Information for more information. Investors
    purchasing Advisor Class shares through financial planners, trust companies,
    bank trust departments or registered investment advisers, or under a "wrap
    fee" program, will be subject to additional fees charged by such entities or
    by the sponsors of such programs. Where any account advised by one of the
    companies composing or affiliated with AMVESCAP PLC invests in Advisor Class
    shares of the Fund, such account shall not be subject to duplicative
    advisory fees.
    
 
   
    The Board of Trustees of the Trust believes that the aggregate per share
    expenses of the Fund and its Portfolio will be approximately equal to the
    expenses the Fund would incur if its assets were invested directly in the
    type of securities being held by its Portfolio.
    
 
   
(3) THE "HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE
    EXPENSES. THE FUND'S AND THE PORTFOLIO'S ACTUAL EXPENSES, AND AN INVESTOR'S
    DIRECT AND INDIRECT EXPENSES, MAY BE MORE OR LESS THAN THOSE SHOWN. The
    table and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds. The 5%
    annual return is not a prediction of and does not represent the Fund's or
    the Portfolio's projected or actual performance.

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
                           AIM GLOBAL RESOURCES FUND
                  (FORMERLY GT GLOBAL NATURAL RESOURCES FUND)
 
   
                                 [TO BE ADDED]
    
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term capital growth. It seeks its
objective by investing all of its investable assets in the Portfolio, which, in
turn, invests primarily in equity securities of companies throughout the world
that own, explore or develop natural resources and other basic commodities or
supply goods and services to such companies. The Portfolio's investment
objective is identical to that of the Fund. There can be no assurance that the
Fund or Portfolio will achieve its investment objective.
    
 
   
At least 65% of the Portfolio's total assets will normally be invested in common
stock and preferred stock, and warrants to acquire such securities, issued by
natural resource companies. A "natural resource" company is an entity in which
(i) at least 50% of either the revenues or earnings was derived from natural
resource activities, or (ii) at least 50% of the assets was devoted to such
activities, based upon the company's most recent fiscal year. The remainder of
the Portfolio's assets may be invested in debt securities issued by natural
resource companies and/or equity and debt securities of companies outside of the
natural resource industries, which, in the opinion of the Sub-adviser, stand to
benefit from developments in the natural resource industries.
    
 
   
GLOBAL RESOURCE INDUSTRIES INVESTMENT. Examples of natural resource companies
include those which own, explore or develop: energy sources (such as oil, gas
and coal); ferrous and non-ferrous metals (such as iron, aluminum, copper,
nickel, zinc and lead), strategic metals (such as uranium and titanium) and
precious metals (such as gold, silver and platinum); chemicals; forest products
(such as timber, coated and uncoated tree sheet, pulp and newsprint); other
basic commodities (such as foodstuffs); refined products (such as chemicals and
steel) and service companies that sell to these producers and refiners; and
other products and services, which, in the Sub-adviser's opinion are significant
to the ownership and development of natural resources and other basic
commodities.
    
 
   
The Sub-adviser believes that the liberalization of formerly socialist economies
will bring about dramatic changes in both the supply and demand for natural
resources. In addition, rapid industrialization in developing countries of Asia
and Latin America is generating new demands for industrial materials that are
affecting world commodities markets. The Sub-adviser believes these changes are
likely to create investment opportunities that benefit from new sources of
supply and/or from changes in commodities prices.
    
 
   
The Sub-adviser also believes that investments in natural resource industries
offer an opportunity to protect wealth against the capital-eroding effects of
inflation. During periods of accelerating inflation or currency uncertainty,
worldwide investment demand for natural resources, particularly precious metals,
tends to increase, and during periods of disinflation or currency stability, it
tends to decrease. The Sub-adviser believes that rising commodity prices and
increasing worldwide industrial production may favorably affect share prices of
natural resource companies, and investments in such companies can offer
excellent opportunities to offset the effects of inflation.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Portfolio expects that, from
time to time, a significant portion of its assets may be invested in the
securities of domestic issuers. The industry represented in the Portfolio,
however, is a global industry with significant, growing markets outside of the
United States. A sizeable proportion of the companies which comprise the natural
resources industries are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Portfolio. The Sub-adviser uses its financial
expertise in markets located throughout the world and the substantial global
resources of AMVESCAP PLC in attempting to identify those countries and
companies then providing the greatest potential for long-term capital
appreciation. In this fashion, the Sub-adviser seeks to enable shareholders to
capitalize on the substantial investment opportunities and the potential for
long-term growth of capital presented by the global natural resources industries
represented in the Portfolio.

                           AIM GLOBAL RESOURCES FUND
 
   
The Sub-adviser allocates the Portfolio's assets among securities of countries
and in currency denominations where opportunities for meeting the Portfolio's
investment objective are expected to be the most attractive. The Portfolio may
invest substantially in securities denominated in one or more currencies. Under
normal conditions, the Portfolio invests in the securities of issuers located in
at least three countries, including the United States; investments in securities
of issuers in any one country, other than the United States, will represent no
more than 50% of the Portfolio's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
In assessing companies for the Resources Portfolio, the Sub-adviser will also
evaluate, among other factors, their capabilities for expanded exploration and
production, superior exploration programs and production techniques and
facilities, current inventories, expected production and demand levels and the
potential to accumulate new resources.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Portfolio may invest up to
100% of its total assets in cash (U.S. dollars, foreign currencies or
multinational currency units such as Euros) and/or high quality debt securities
or money market instruments of U.S. or foreign issuers. In addition, for
temporary defensive purposes, most or all of the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Portfolio adopts a temporary defensive posture, it will not be invested so as to
achieve directly its investment objective. In addition, pending investment of
proceeds from new sales of Fund shares or to meet its ordinary daily cash needs,
the Portfolio may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and may invest in foreign or domestic high quality money market
instruments. For a full description of money market instruments, see "Money
Market Instruments" in the "Investment Objectives and Policies" section of the
Statement of Additional Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Portfolio in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Portfolio to participate in privatizations may be limited by local
law, or the terms on which the Portfolio may be permitted to participate may be
less advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Portfolio may invest up to 10% of
its total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Portfolio
would bear its ratable share of that investment company's expenses, including
its advisory and administration fees. At the same time, the Portfolio would
continue to pay its own management fees and other expenses. AIM and the
Sub-adviser will waive their advisory fees to the extent that the Portfolio
invests in an Affiliated Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Portfolio
may borrow from banks or may borrow through reverse repurchase agreements and
"roll" transactions in connection with meeting requests for the redemptions of
the Funds' shares. The Portfolio also may borrow up to 5% of its total assets
for temporary or emergency purposes other than to meet redemptions of the Funds'
shares. The Portfolio may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Portfolio's borrowings exceed 5% of
its total assets. Any borrowing by the Portfolio may cause greater fluctuation
in the value of its shares than would be the case if the Portfolio did not
borrow.

<PAGE>
                           AIM GLOBAL RESOURCES FUND
 
   
A reverse repurchase agreement is a borrowing transaction in which the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Portfolio's sale of securities together with
its commitment (for which the Portfolio may receive a fee) to purchase similar,
but not identical, securities at a future date.
    
 
   
SECURITIES LENDING. The Portfolio may lend its portfolio securities to
broker/dealers or to other institutional investors. Securities lending allows
the Portfolios to retain ownership of the securities loaned and, at the same
time, enhances the Fund's total return. The Portfolio limits its loans of
portfolio securities to an aggregate of 30% of the value of its total assets,
measured at the time any such loan is made. While a loan is outstanding, the
borrower must maintain with the Portfolio's custodian collateral consisting of
cash, U.S. government securities or certain irrevocable letters of credit equal
to at least the value of the borrowed securities, plus any accrued interest or
such other collateral as permitted by the Portfolio's investment program and
regulatory agencies, and as approved by the Board. The risks in lending
portfolio securities, as with other extensions of secured credit, consist of
possible delays in receiving additional collateral or in recovery of the
securities and possible loss of rights in the collateral should the borrower
fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Portfolio may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Portfolio will
purchase or sell when-issued securities or enter into forward commitments only
with the intention of actually receiving or delivering the securities, as the
case may be. No income accrues on securities that have been purchased pursuant
to a forward commitment or on a when-issued basis prior to delivery to the
Portfolio. If the Portfolio disposes of the right to acquire a when-issued
security prior to its acquisition or disposes of its right to deliver or receive
against a forward commitment, it may incur a gain or loss. At the time the
Portfolio enters into a transaction on a when-issued or forward commitment
basis, the Portfolio will segregate cash or liquid securities equal to the value
of the when-issued or forward commitment securities with its custodian and will
mark to market daily such assets. There is a risk that the securities may not be
delivered and that the Portfolio may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Portfolio may use
forward currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Portfolio may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Portfolio may enter into forward currency contracts for the
purchase or sale of a specified currency at a specified future date. Such
contracts may involve the purchase or sale of a foreign currency against the
U.S. dollar or may involve two foreign currencies. The Portfolio may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Portfolio also may purchase and sell put
and call options on currencies, futures contracts on currencies and options on
such futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Portfolio may purchase and sell put and call options on equity
and debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Portfolio or that the Sub-adviser intends to include in
the Portfolio's holdings. The Portfolio also may purchase and sell put and call
options on stock indexes to hedge against overall fluctuations in the securities
markets generally or in a specific market sector.
    
 
   
Further, the Portfolio may sell stock index futures contracts and may purchase
put options or write
    
 
                               Prospectus Page 9
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
call options on such futures contracts to protect against a general stock market
decline or a decline in a specific market sector that could affect adversely the
Portfolio's holdings. The Portfolio also may purchase stock index futures
contracts and purchase call options or write put options on such contracts to
hedge against a general stock market or market sector advance and thereby
attempt to lessen the cost of future securities acquisitions. The Portfolio may
use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of that Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval.
    
 
   
The approval of the Fund and of other investors in the Portfolio, if any, is not
required to change the investment objective, policies or limitations of the
Portfolio, unless otherwise specified. Written notice shall be provided to
shareholders of the Fund thirty days prior to any changes in the Portfolio's
investment objective.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's or Portfolio's investment policies or
restrictions.
    
 
   
The Portfolio is authorized to engage in Short Sales, although it currently has
no intention of doing so, and may purchase American Depository Receipts,
American Depository Shares, Global Depository Receipts and European Depository
Receipts. See "Short Sales" and "Depository Receipts," respectively, in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, the Fund,
unlike mutual funds that directly acquire and manage their own portfolios of
securities, seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which is a separate investment company.
Because the Fund will invest only in the Portfolio, the Fund's shareholders will
acquire only an indirect interest in the investments of the Portfolio.
    
 
   
The Fund may redeem its investment in the Portfolio at any time, if the Board of
Trustees of the Trust determines that it is in the best interests of the Fund
and its shareholders to do so. A change in the Portfolio's investment objective,
policies or limitations that is not approved by the Board or the shareholders of
the Fund could require the Fund to redeem its interest in the Portfolio. Any
such redemption could result in a distribution in kind of portfolio securities
(as opposed to a cash distribution) by the Portfolio. Should such a distribution
occur, the Fund could incur brokerage fees or other transaction costs in
converting such securities to cash. In addition, a distribution in kind could
result in a less diversified portfolio of investments for the Fund and could
adversely affect its liquidity. Upon redemption, the Board would consider what
action might be taken, including the investment of all the investable assets of
the Fund in another pooled investment entity having substantially the same
investment objective as the Fund or the retention by the Fund of its own
investment adviser to manage its assets in accordance with its investment
objective, policies and limitations discussed herein.
    
 
   
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may
    
 
                               Prospectus Page 10
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
experience different returns than investors in another investment company that
invests exclusively in the Portfolio. As of the date of this Prospectus, the
Fund is the only institutional investor in the Portfolio.
    
 
   
The Fund may be materially affected by the actions of other large investors, if
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund or the Portfolio will achieve its
investment objective. The Fund's net asset values will fluctuate reflecting
fluctuations in the market value of the Portfolio's securities. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure, and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Portfolio will
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities. In addition,
the value of debt securities held by the Portfolio generally will fluctuate with
changes in the perceived creditworthiness of the issuers of such securities and
interest rates.
    
 
   
Because the Portfolio focuses its investments on the natural resources
industries, an investment in it may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
Moreover, the value of the shares of the Fund will be especially susceptible to
factors affecting the natural resources industries in which it focuses.
Accordingly, the Fund should not be considered a complete investment program.
    
 
   
NATURAL RESOURCES INDUSTRIES. Natural resource industries may be subject to
greater political, environmental and other governmental regulation than many
other industries. The nature of such regulation continues to evolve in both the
United States and foreign countries, and changes in governmental policies and
the need for regulatory approvals may have a material effect on the products and
services offered by companies in the natural resource industries. For example,
the exploration, development and distribution of coal, oil and gas in the United
States are subject to significant federal and state regulation, which may affect
rates of return on such investments and the kinds of services that may be
offered. Governmental regulation may also hamper the development of new
technologies.
    
 
   
In addition, many natural resource companies historically have been subject to
significant costs associated with compliance with environmental and other safety
regulations. Further, competition is intense for many natural resource
companies. As a result, many of these companies may be adversely affected in the
future and the value of the securities issued by such companies may be subject
to increased share price volatility. Such companies may also be subject to
irregular fluctuations in earnings due to changes in the availability of money,
the level of interest rates, and other factors.
    
 
   
The value of securities of natural resource companies will fluctuate in response
to market conditions for the particular natural resources with which the issuers
are involved. The price of natural resources will fluctuate due to changes in
worldwide levels of inventory, and changes, perceived or actual, in production
and consumption. With respect to precious metals, such price fluctuations may be
substantial over short periods of time. In addition, the value of natural
resources may fluctuate directly with respect to various stages of the
inflationary cycle and perceived inflationary trends and are subject to numerous
factors, including national and international politics.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
    
 
                               Prospectus Page 11
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Portfolio's interest and dividends from foreign issuers may be
subject to non-U.S. withholding taxes, thereby reducing the Portfolio's net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Portfolio, political or social instability, or diplomatic
developments which could affect the Portfolio's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Portfolio may invest in issuers domiciled in "emerging markets." Investing
in emerging market countries involves risks in addition to those risks involved
in foreign investing. Many emerging market countries have experienced high rates
of inflation for many years. In addition, emerging markets generally are
dependent heavily upon international trade and, accordingly, have been and
continue to be affected adversely by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed
or negotiated by the countries with which they trade. The securities markets of
emerging market countries are substantially smaller, less developed, less liquid
and more volatile than the securities markets of the developed countries. In
addition, issuers in emerging markets typically are subject to a greater degree
of change in earnings and business prospects than issuers in developed
countries.
    
 
   
The Portfolio will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Portfolio and gains and losses realized by the Portfolio.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Portfolio may invest up to 20%, of its total
assets in below investment grade debt securities, that is, rated below BBB by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa
by Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Portfolio will not invest in debt securities
that are in default as to payment of principal and interest.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
    
 
                               Prospectus Page 12
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Portfolio. If an issuer exercises these provisions in a
declining interest rate market, the Portfolio may have to replace the security
with a lower yielding security, resulting in a decreased return for investors.
In addition, the Portfolio may have difficulty disposing of lower quality
securities because they may have a thin trading market. There may be no
established retail secondary market for many of these securities, and the
Portfolio anticipates that such securities could be sold only to a limited
number of dealers or institutional investors. The lack of a liquid secondary
market also may have an adverse impact on market prices of such instruments and
may make it more difficult for the Portfolio to obtain accurate market
quotations for purposes of valuing its investments. The Portfolio may also
acquire lower quality debt securities during an initial underwriting or which
are sold without registration under applicable securities laws. Such securities
involve special considerations and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Portfolio may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Portfolio may also incur additional expenses to the
extent it is required to seek recovery upon a default in the payment of
principal or interest on portfolio holdings, and the Portfolio may have limited
legal recourse in the event of a default.
    
 
   
ILLIQUID SECURITIES. The Portfolio may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Portfolio to
achieve capital appreciation substantially exceeding the appreciation the
Portfolio would realize if they did not make such investments. However, in order
to attempt to limit investment risk, the Portfolio will invest no more than 5%
of its total assets in Special Situations.
    
 
   
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Portfolio is
authorized to enter into options, futures and forward currency transactions, the
Portfolio might not enter into any such transactions. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Portfolio invests; (4) lack
of assurance that a liquid secondary market will exist for any particular
option, futures contract or option thereon at any particular time; (5) the
possible loss of principal under certain conditions; and (6) the possible
inability of the Portfolio to purchase or sell a portfolio security at a time
when it would otherwise be favorable for it to do so, or the possible need for
the
    
 
                               Prospectus Page 13
<PAGE>
                           AIM GLOBAL RESOURCES FUND
   
Portfolio to sell a security at a disadvantageous time, due to the need for the
Portfolio to maintain "cover" or to set aside securities in connection with
hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Portfolio's holdings normally will
include securities of established suppliers of traditional products and
services, the Portfolio may invest in smaller companies which can benefit from
the development of new products and services. These smaller companies may
present greater opportunities for capital appreciation, but may also involve
greater risks than large, established issuers. Such smaller companies may have
limited product lines, markets or financial resources, and their securities may
trade less frequently and in more limited volume than the securities of larger,
more established companies. As a result, the prices of the securities of such
smaller companies may fluctuate to a greater degree than the prices of the
securities of other issuers.
    
 
- --------------------------------------------------------------------------------
 
                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees and the Board of Trustees of the Portfolio have
overall responsibility for the operation of the Fund and the Portfolio,
respectively. The Boards have approved all significant agreements between the
Trust and the Portfolio on the one side and persons or companies furnishing
services to the Fund and the Portfolio on the other, including the investment
management and administrative services agreement with AIM, the investment
sub-advisory and sub-administration agreement between AIM and the Sub-adviser,
the agreements with AIM Distributors regarding distribution of the Fund's
shares, the custody agreement and the transfer agency agreement. The day-to-day
operations of the Fund and the Portfolio are delegated to the officers of the
Trust and the Portfolio, subject always to the investment objective and policies
of the Fund and the Portfolio and to the general supervision of the Boards. See
"Trustees and Executive Officers" in the Statement of Additional Information for
information on the Trust's and the Portfolio's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the investment managers to the Fund and the Portfolio include,
but are not limited to, determining the composition of the investment portfolio
of the Portfolio and placing orders to buy, sell or hold particular securities.
In addition, AIM and the Sub-adviser provide the following administration
services to the Portfolio and the Fund: furnishing corporate officers and
clerical staff; providing office space, services and equipment; and supervising
all matters relating to the Portfolio's and the Fund's operation.
    
 
   
For administration services, the Fund pays AIM administration fees computed
daily and payable monthly at the annualized rate of 0.25% of the Fund's average
daily net assets. AIM has appointed the Sub-adviser as the Fund's
sub-administrator. In addition, the Fund bears its pro rata portion of the
investment management and administration fees paid by its corresponding
Portfolio to AIM and the Sub-adviser. The Portfolio pays AIM a fee, based on the
Portfolio's average daily net assets at the annualized rate of .725% on the
first $500 million, .70% on the next $500 million, .675% on the next $500
million and .65% on all amounts thereafter. Out of its aggregate fees payable by
the Fund and the Portfolio, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund and the Portfolio. The investment management and administration fees paid
by the Fund and the Portfolio are higher than those paid by most mutual funds.
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 1.50% of the average daily net assets of the Fund's Advisor Class
shares.
    
 
   
The Sub-adviser also serves as the Fund's and the Portfolio's pricing and
accounting agent. For these services the Sub-adviser receives a fee consisting
of 0.03% of the first $5 billion of assets, and 0.02% of the assets in excess of
$5 billion, of the AIM Funds that are sub-advised by the Sub-adviser (other than
AIM Eastern Europe Fund). Each of these funds, including the Fund and the

AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Portfolio pursuant to a master investment management
and administrative services agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Portfolio pursuant to
an investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Portfolio, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
The investment professional primarily responsible for the portfolio management
of the Portfolio is as follows:

In placing orders for the Portfolio's securities transactions, the Sub-adviser
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Sub-adviser may consider a broker/dealer's sale of
shares of the AIM Funds as a factor in considering through whom portfolio
transactions will be effected. Brokerage transactions may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Funds will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Company acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders have no preemptive rights. Other than the automatic
conversion of Class B shares to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Company's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund when issued are fully paid and
nonassessable.
    
 
   
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a subtrust of
Global Investment Portfolio, a Delaware business trust. Under Delaware law, the
Fund and other entities investing in the Portfolio enjoy the same limitations of
liability extended to shareholders of private, for-profit corporations. There is
a remote possibility, however, that under certain circumstances an investor in
the Portfolio may be held liable for the Portfolio's obligations. However, the
Agreement and Declaration of Trust of Global Investment Portfolio disclaims
shareholder liability for acts or obligations of the Portfolio and requires that
notice of such disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Portfolio or a trustee. The Agreement and
Declaration of Trust also provides for indemnification from the Portfolio
property for all losses and expenses of any shareholder held personally liable
for the Portfolio's obligations. Thus the risk of an investor incurring
financial loss on account of such liability is limited to circumstances in which
the Portfolio itself would be unable to meet its obligations and where the other
party was held not to be bound by the disclaimer.
    
 
   
Whenever the Fund is requested to vote on any proposal of the Portfolio, the
Fund will hold a meeting of the Fund's shareholders and will cast its vote as
instructed by its shareholders. Shares for which no voting instructions are
received will be voted in the same proportion as the shares for which voting
instructions are received.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust, to the Fund and
to the Portfolio.

trust department or registered investment adviser has investment discretion over
the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is
established under a "wrap fee" program and (ii) the account holder pays the
sponsor of such program an annual fee of at least .50% of the assets in the

<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in

the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]

EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7

                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.
    
 
   
    AIM DEVELOPING MARKETS FUND, AIM EMERGING MARKETS FUND, AIM EUROPE GROWTH

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.

portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer

    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and

    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

The Fund:                      The Fund is a diversified series of the Trust.
 
Investment Objective:          The Fund seeks long-term growth of capital.

                               subsidiaries of  AMVESCAP  PLC. AMVESCAP  PLC  and its  subsidiaries  are an  independent  investment
                               management  group that  has a  significant presence in  the institutional  and retail  segment of the

                               advised  by the  Sub-adviser or one  of the companies  formerly affiliated with  the Asset Management
                               Division of Liechtenstein  Global Trust AG,  provided such  accounts were invested  in Advisor  Class
                               shares  of any of the funds in The AIM Family  of Funds that are sub-advised by the Sub-adviser ("AIM
                               Funds") on May 29, 1998; (e) any of the companies composing or affiliated with AMVESCAP PLC; and  (f)
                               AIM  Global Trends Fund. Pursuant to a separate prospectus,  the Fund also offers Class A and Class B
                               shares, which  represent interests  in  the Fund.  The Class  A  and Class  B shares  have  different
                               distribution arrangements.
 
                               Initial  investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least  $50. The  distributor  of the  Advisor  Class shares  is A  I  M Distributors,  Inc.  ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
 
Exchange Privilege:            The  Fund is among those mutual funds distributed  by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Advisor Class  shares of the Fund  may be exchanged for  Advisor Class shares of  certain
                               Funds  in The AIM  Family of Funds in  the manner and  subject to the policies  and charges set forth
                               herein. See "Exchange Privilege."
 
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at the Fund's  net
                               asset value on any business day. See "How to Redeem Shares."
 
Distributions:                 The  Fund currently  declares and pays  dividends from  net investment income,  if any,  on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis.  Dividends
                               and  distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds.  See
                               "Dividends, Distributions and Tax Matters."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset value
                               will  fluctuate, reflecting fluctuations  in the market  value of its  portfolio holdings. The Fund's
                               policy of concentrating  its investments  in companies  in its  particular industries  may cause  the
                               Fund's net asset value to fluctuate more than if it invested in a greater number of industries.
 
                               The  Fund may invest in foreign securities.  Investments in foreign securities involve risks relating
                               to political and economic developments  abroad and the differences  between the regulations to  which
                               U.S.  and foreign  issuers are  subject. Individual  foreign economies  also may  differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the  Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies  may be less liquid and  their prices more volatile than  those of securities of comparable
                               U.S. companies.
 
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and

                               The  Fund  may invest  up  to 5%  of its  total  assets in  below  investment grade  debt securities.

The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is long-term growth of capital. It seeks its
objective by investing primarily in equity securities of companies throughout
the world engaged in the development, manufacture or sale of telecommunications
services or equipment. There can be no assurance that the Fund will achieve its
investment objective.
    
 
   
At least 65% of the Fund's total assets normally will be invested in common and
preferred stocks and warrants to acquire such securities issued by
telecommunications companies. A "telecommunications" company is an entity in
which (i) at least 50% of either its revenues or earnings was derived from
telecommunications activities, or (ii) at least 50% of its assets was devoted to
telecommunications activities, based on the company's most recent fiscal year.
The remainder of the assets of the Fund may be invested in debt securities
issued by telecommunications companies and/or equity and debt securities of
companies outside of the telecommunications industry which, in the opinion of
the Sub-adviser, stand to benefit from developments in the telecommunications
industries.
    
 
   
GLOBAL TELECOMMUNICATIONS INDUSTRIES INVESTMENT. Telecommunications companies
cover a variety of sectors, ranging from companies concentrating on established
technologies to those primarily engaged in emerging or developing technologies.
The characteristics of companies focusing on the same technology will vary among
countries depending upon the extent to which the technology is established in
the particular country. The Sub-adviser will allocate the Fund's investments
among these sectors depending upon its assessment of their relative long-term
growth potential.
    
 
   
Examples of telecommunications companies include those engaged in designing,
developing or providing the following products and services: communications
equipment and services (including equipment and services for both data and voice
transmission); electronic components and equipment; broadcasting (including
television and radio, satellite, microwave and cable television and
narrowcasting); computer equipment, mobile communications and cellular
radio/paging; electronic mail; local and wide area networking and linkage of
word and data processing systems; publishing and information systems; videotext
and teletext; and emerging technologies combining telephone, television and/or
computer systems.
    
 
   
The Sub-adviser believes that there are opportunities for continued growth in
demand for components, products, media and systems to collect, store, retrieve,
transmit, process, distribute, record, reproduce and use information. The
pervasive societal impact of communications and information technologies has
been accelerated by the lower costs and higher efficiencies that result from the
blending of computers with telecommunications systems. Accordingly, companies
engaged in the production of methods for using electronic and, potentially,
video technology to communicate information are expected to be important in the
Fund's portfolio. Older technologies, such as photography and print also may be
represented, however.
    
 
   
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. The Fund expects that, from time
to time, a significant portion of its assets may be invested in the securities
of domestic issuers. The industry represented in the Fund, however, is a global
industry with significant, growing markets outside of the United States. A
sizeable proportion of the companies which comprise the telecommunications
industry are headquartered outside of the United States.
    
 
   
For these reasons, the Sub-adviser believes that a portfolio composed only of
securities of U.S. issuers does not provide the greatest potential for return
from an investment by the Fund. The Sub-adviser uses its financial expertise in
markets located throughout the world and the substantial global resources of
AMVESCAP PLC in attempting to identify those countries and companies then
providing the greatest potential for long-term capital appreciation. In this
fashion, the Sub-adviser seeks to enable shareholders to capitalize on the
substantial investment opportunities and the potential for long-term growth of
capital presented by the global industry represented in the Fund.
    
 
                               Prospectus Page 6
<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
 
   
The Sub-adviser allocates the Fund's assets among securities of countries and in
currency denominations where opportunities for meeting the Fund's investment
objective are expected to be the most attractive. The Fund may invest
substantially in securities denominated in one or more currencies. Under normal
conditions, the Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 40% of the Fund's total assets.
    
 
   
In analyzing specific companies for possible investment, the Sub-adviser
ordinarily looks for several of the following characteristics: above-average per
share earnings growth; high return on invested capital; a healthy balance sheet;
sound financial and accounting policies and overall financial strength; strong
competitive advantages; effective research and product development and
marketing; development of new technologies; efficient service; pricing
flexibility; strong management; and general operating characteristics that will
enable the companies to compete successfully in their respective markets.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Sub-adviser may employ a temporary defensive investment strategy if
it determines such a strategy to be warranted due to market, economic or
political conditions. Under a defensive strategy, the Fund may invest up to 100%
of its total assets in cash (U.S. dollars, foreign currencies or multinational
currency units such as Euros) and/or high quality debt securities or money
market instruments of U.S. or foreign issuers. In addition, for temporary
defensive purposes, most or all of the Fund's investments may be made in the
United States and denominated in U.S. dollars. To the extent the Fund adopts a
temporary defensive posture, it will not be invested so as to achieve directly
its investment objective. In addition, pending investment of proceeds from new
sales of Fund shares or to meet its ordinary daily cash needs, the Fund may hold
cash (U.S. dollars, foreign currencies or multinational currency units) and may
invest in foreign or domestic high quality money market instruments. For a full
description of money market instruments, see "Money Market Instruments" in the
"Investment Objectives and Policies" section of the Statement of Additional
Information.
    
 
   
PRIVATIZATIONS. The governments of some foreign countries have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain foreign countries, the ability of foreign entities
such as the Fund to participate in privatizations may be limited by local law,
or the terms on which the Fund may be permitted to participate may be less
advantageous than those for local investors. There can be no assurance that
foreign governments will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
    
 
   
INVESTMENTS IN OTHER INVESTMENT COMPANIES. The Fund may invest up to 10% of its
total assets in other investment companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). As a shareholder in an investment company, the Fund would
bear its ratable share of that investment company's expenses, including its
advisory and administration fees. At the same time, the Fund would continue to
pay its own management fees and other expenses. AIM and the Sub-adviser will
waive their advisory fees to the extent that the Fund invests in an Affiliated
Fund.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemptions of the
Fund's shares. The Fund also may borrow up to 5% of its total assets for
temporary or emergency purposes other than to meet redemptions of the Fund's
shares. The Fund may borrow up to 33 1/3% of its total assets. However, no
additional investments will be made if the Fund's borrowings exceed 5% of its
total assets. Any borrowing by the Fund may cause greater fluctuation in the
value of its shares than would be the case if the Fund did not borrow.
    
 
   
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Fund's sale of securities together with its
commitment (for which the Fund may receive a fee) to purchase similar, but not
identical, securities at a future date.

<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least the value of the
borrowed securities, plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral should the borrower fail financially.
    
 
   
WHEN-ISSUED OR FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities or enter into forward commitments only with the
intention of actually receiving or delivering the securities, as the case may
be. No income accrues on securities that have been purchased pursuant to a
forward commitment or on a when-issued basis prior to delivery to the Fund. If
the Fund disposes of the right to acquire a when-issued security prior to its
acquisition or disposes of its right to deliver or receive against a forward
commitment, it may incur a gain or loss. At the time the Fund enters into a
transaction on a when-issued or forward commitment basis, the Fund will
segregate cash or liquid securities equal to the value of the when-issued or
forward commitment securities with its custodian and will mark to market daily
such assets. There is a risk that the securities may not be delivered and that
the Fund may incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the portfolio. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Fund may enter into such
instruments up to the full value of its portfolio assets. See "Risk Factors --
Options, Futures and Forward Currency Transactions" herein and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Sub-adviser intends to include in the
Fund's portfolio. The Fund also may purchase and sell put and call options on
stock indexes to hedge against overall fluctuations in the securities markets
generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
affect adversely the Fund's holdings. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolio against changes in the general level of interest rates.

OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the Fund's shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Trust's
Board of Trustees without shareholder approval. The Fund's policies regarding
concentration and lending, and the percentage of the Fund's assets that may be
committed to borrowing, are fundamental policies and may not be changed without
shareholder approval.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securties
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
- --------------------------------------------------------------------------------
 
   
                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. The Fund's net asset value will fluctuate reflecting fluctuations in
the market value of the Fund's positions. Equity securities, particularly common
stocks, generally represent the most junior position in an issuer's capital
structure, and entitle holders to an interest in the assets of an issuer, if
any, remaining after all more senior claims have been satisfied. The value of
equity securities held by the Fund will fluctuate in response to general market
and economic developments, as well as developments affecting the particular
issuers of such securities. In addition, the value of debt securities held by
the Fund generally will fluctuate with changes in the perceived creditworthiness
of the issuers of such securities and interest rates.
    
 
   
Because the Fund focuses its investments on particular industries, an investment
in the Fund may be more volatile than that of other investment companies that do
not concentrate their investments in such a manner. Moreover, the value of the
shares of the Fund will be especially susceptible to factors affecting the
industries in which it focuses. Accordingly, the Fund should not be considered a
complete investment program.
    
 
   
TELECOMMUNICATIONS INDUSTRIES. Telecommunications industries may be subject to
greater governmental regulation than many other industries and changes in
governmental policy and the need for regulatory approvals may have a material
effect on the products and services offered by companies in the
telecommunications industries. Telephone operating companies in the United
States, for example, are subject to both federal and state regulation affecting
permitted rates of return and the kinds of services that may be offered. Certain
types of companies in the telecommunications industries are engaged in fierce
competition for market share that could result in increased share price
volatility.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to, the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs
    
 
                               Prospectus Page 9
<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
   
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Fund's interest and dividends from foreign
issuers may be subject to non-U.S. withholding taxes, thereby reducing the
Fund's net investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the Fund's investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
The Fund may invest in issuers domiciled in "emerging markets." Investing in
emerging market countries involves risks in addition to those risks involved in
foreign investing. Many emerging market countries have experienced high rates of
inflation for many years. In addition, emerging markets generally are dependent
heavily upon international trade and, accordingly, have been and continue to be
affected adversely by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. The securities markets of emerging
market countries are substantially smaller, less developed, less liquid and more
volatile than the securities markets of the developed countries. In addition,
issuers in emerging markets typically are subject to a greater degree of change
in earnings and business prospects than issuers in developed countries.
    
 
   
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between foreign currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
    
 
   
LOWER QUALITY DEBT SECURITIES. The Fund may invest up to 5% of its total assets
in below investment grade debt securities, that is, rated below BBB by Standard
& Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), or Baa by
Moody's Investors Service, Inc. ("Moody's") or, if unrated, deemed to be of
equivalent quality in the judgment of the Sub-adviser. Such investments involve
a high degree of risk. However, the Fund will not invest in debt securities that
are in default as to payment of principal and interest.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest rated debt that is not in default as to
principal or interest, and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than securities with higher ratings with regard to a deterioration of
general economic conditions. These lower quality debt securities are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Description of Debt Ratings" in the Statement of Additional Information for a
full discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained

period of rising interest rates, highly leveraged issuers of lower quality
securities may experience financial stress. During such periods, such issuers
may not have sufficient revenues to meet their interest payment obligations. The
issuer's ability to service its debt obligations may also be adversely affected
by specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Fund. If an issuer exercises these provisions in a declining
interest rate market, the Fund may have to replace the security with a lower
yielding security, resulting in a decreased return for investors. In addition,
the Fund may have difficulty disposing of lower quality securities because they
may have a thin trading market. There may be no established retail secondary
market for many of these securities, and the Fund anticipates that such
securities could be sold only to a limited number of dealers or institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on market prices of such instruments and may make it more difficult for the Fund
to obtain accurate market quotations for purposes of valuing the Fund's
portfolio investments. The Fund may also acquire lower quality debt securities
during an initial underwriting or which are sold without registration under
applicable securities laws. Such securities involve special considerations and
risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession. The Fund may also incur additional expenses to the extent it
is required to seek recovery upon a default in the payment of principal or
interest on portfolio holdings, and the Fund may have limited legal recourse in
the event of a default.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets in
securities for which no readily available market exists, so-called "illiquid
securities." The Sub-adviser believes that carefully selected investments in
joint ventures, cooperatives, partnerships and state enterprises which are
illiquid (collectively, "Special Situations") could enable the Fund to achieve
capital appreciation substantially exceeding the appreciation the Fund would
realize if it did not make such investments. However, in order to attempt to
limit investment risk, the Fund will invest no more than 5% of its total assets
in Special Situations.
    
 
   
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets or in the appropriate
market sector and movements in interest rates and currency markets; (2)
imperfect correlation, or even no correlation, between movements in the price of
options, forward contracts, futures contracts or options thereon and movements
in the price of the currency or security hedged or used for cover; (3) the fact
that skills and techniques needed to trade options, futures contracts and
options thereon or to use forward currency contracts are different from those
needed to select the securities in which the Fund invests; (4) lack of assurance
that a liquid secondary market will exist for any particular option, futures
contract or option thereon at any particular time; (5) the possible loss of
principal under certain conditions; and (6) the possible inability of the Fund
to purchase or sell a portfolio security at a time when it would otherwise be
favorable for it to do so, or the possible need for the Fund to sell a security
at a disadvantageous time, due to the need for the Fund to maintain "cover" or
to set aside securities in connection with hedging transactions.
    
 
   
INVESTING IN SMALLER COMPANIES. While the Fund's portfolio normally will include
securities of established suppliers of traditional products and
    
 
                               Prospectus Page 11
<PAGE>
                       AIM GLOBAL TELECOMMUNICATIONS FUND
   
services, the Fund may invest in smaller companies which can benefit from the
development of new products and services. These smaller companies may present
greater opportunities for capital appreciation, but may also involve greater
risks than large, established issuers. Such smaller companies may have limited
product lines, markets or financial resources, and their securities may trade
less frequently and in more limited volume than the securities of larger, more
established companies. As a result, the prices of the securities of such smaller
companies may fluctuate to a greater degree than the prices of the securities of
other issuers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust and persons or companies furnishing services to the Fund on
the other, including the investment management and administration agreement with
AIM, the investment sub-advisory and sub-administration agreement between AIM
and the Sub-adviser, the agreements with AIM Distributors regarding distribution
of the Fund's shares, the custody agreement and the transfer agency agreement.
The day-to-day operations of the Fund are delegated to the officers of the
Trust, subject always to the investment objective and policies of the Fund and
to the general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers include, but are not limited to,
determining the composition of the investment portfolio of the Fund and placing
orders to buy, sell or hold particular securities. In addition, AIM and the
Sub-adviser provide the following administration services to the Fund:
furnishing corporate officers and clerical staff; providing office space,
services and equipment; and supervising all matters relating to the Fund's
operation.
    
 
For investment management and administration services provided to the Fund, the
Fund pays AIM a fee computed daily and paid monthly based on the Fund's average
daily net assets at the annualized rate of .975% on the first $500 million, .95%
on the next $500 million, .925% on the next $500 million and .90% on amounts
thereafter. Out of the aggregate fees payable by the Fund, AIM pays the
Sub-adviser sub-advisory and sub-administration fees equal to 40% of the
aggregate fees AIM receives from the Fund.
 
   
The Fund pays all expenses not assumed by AIM, the Sub-adviser, AIM Distributors
or other agents. AIM has undertaken to limit the Fund's expenses (exclusive of
brokerage commissions, taxes, interest and extraordinary expenses) to the annual
rate of 1.50% of the average daily net assets of the Fund's Advisor Class
shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administrative services agreement, dated as of May 29, 1998 (the "Advisory
Agreement"). AIM was organized in 1976 and, together with its subsidiaries,
manages or advises approximately 90 investment company portfolios encompassing a
broad range of investment objectives. The Sub-adviser, 50 California Street,
27th Floor, San Francisco, California 94111, and 1166 Avenue of the Americas,
New York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase

agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
   
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices in Atlanta, Boston, Dallas, Denver, Louisville,
Miami, Portland (Oregon), Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo
and Toronto. In managing the Fund, the Sub-adviser employs a team approach,
taking advantage of its investment resources around the world.
    
 
The investment professional primarily responsible for the portfolio management
of the Fund is as follows:

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions may be executed through affiliates of
AIM or the Sub-adviser. High portfolio turnover (over 100%) involves
correspondingly greater brokerage commissions and other transaction costs that
the Funds will bear directly and could result in the realization of net capital
gains which would be taxable when distributed to shareholders. See "Dividends,
Distributions and Tax Matters."
    
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Company. From time to time, the Company has established and may continue
to establish other funds, each corresponding to a distinct investment portfolio
and a distinct series of the Trust's shares of beneficial interest. Shares of
each fund are entitled to one vote per share (with proportional voting for
fractional shares) and are freely transferable. Shareholders

have no preemptive rights. Other than the automatic conversion of Class B shares
to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the Fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges, except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.

<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in
    
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                        PROSPECTUS -- SEPTEMBER 8, 1998
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Latin American Growth Fund (The
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end, series, management investment
company. The Fund is a non-diversified portfolio which seeks capital
appreciation by investing primarily in equity and debt securities of a broad
range of Latin American issuers.
    
 
   
The Fund is designed for long term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in lower quality and unrated
foreign government bonds whose credit quality is generally considered the
equivalent of U.S. corporate debt securities commonly known as "junk bonds."
Investments of this type are subject to a greater risk of loss of principal and
interest. An investment in the Fund should be considered speculative and subject
to special risk factors, related primarily to the Fund's investments in Latin
America. Purchasers should carefully assess the risks associated with an
investment in the Fund.
    
 
   
This Prospectus sets forth concisely the information about the Fund that
prospective investors should know before investing. It should be read and
retained for future reference. A Statement of Additional Information dated
September 8, 1998 has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated herein by reference. The Statement of Additional
Information is available without charge upon written request to the Trust at 11
Greenway Plaza, Suite 100, Houston, Texas 77046-1173 or by calling
1-800-347-4246. The SEC maintains a Web site at http://www.sec.gov that contains
the Statement of Additional Information, material incorporated by reference, and
other information regarding the Fund. Additional information about the Fund may
also be obtained from http://www.aimfunds.com.

                               Pursuant to a separate prospectus, the Fund also offers Class A and Class B shares, which represent
                               interests in the Fund. The Class A and Class B shares have different distribution arrangements.
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               funds in The AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."

                               on any business day. See "How to Redeem Shares."
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on an annual
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
Risk Factors:                  There is no assurance that the Fund will achieve its investment objective. The Fund's net asset
                               values will fluctuate, reflecting fluctuations in the market value of the portfolio holdings.
                               The Fund will invest primarily in foreign securities. Investments in foreign securities involve risks
                               relating to political and economic developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies.
                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
                               There is no limitation on the percentage of the Fund's total assets that may be invested in below
                               investment grade debt securities. Investments of this type are subject to a greater risk of loss of
                               principal and interest.
                               See "Investment Objective and Policies" and "Risk Factors."

- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. This information is
supplemented by the financial statements and accompanying notes appearing in the
Statement of Additional Information.
    
 
                         AIM LATIN AMERICAN GROWTH FUND
                 (FORMERLY GT GLOBAL LATIN AMERICA GROWTH FUND)

                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of the Fund. Such practices will
have the effect of increasing the Fund's total return. The performance of the
Fund will vary from time to time and past results are not necessarily
representative of future results. The Fund's performance is a function of its
portfolio management in selecting the type and quality of portfolio securities
and is affected by operating expenses of the Fund as well as by general market
conditions.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund's investment objective is capital appreciation. The Fund normally
invests at least 65% of its total assets in the securities of a broad range of
Latin American issuers. The Fund may invest in common stock, preferred stock,
rights, warrants and securities convertible into common stock, and other
substantially similar forms of equity securities with comparable risk
characteristics, as well as bonds, notes, debentures or other forms of
indebtedness that may be developed in the future. Normally, the Fund will invest
a majority of its assets in equity securities. The Fund may also invest up to
35% of its total assets in a combination of equity and debt securities of U.S.
issuers. There can be no assurance that the Fund will meet its investment
objective.
    
 
   
For purposes of this Prospectus, unless otherwise indicated, the Fund defines
Latin America to include the following countries: Argentina, the Bahamas,
Barbados, Belize, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican
Republic, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Haiti,
Honduras, Jamaica, Mexico, the Netherlands Antilles, Nicaragua, Panama,
Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay and Venezuela. Under
current market conditions, the Fund expects to invest primarily in securities
issued by companies and governments in Mexico, Chile, Brazil and Argentina. The
Fund may invest more than 25% of its total assets in any of these four countries
but does not expect to invest more than 60% of its total assets in any one
country.
    
 
   
The Fund defines securities of Latin American issuers to include: (a) securities
of companies organized under the laws of, or having a principal office located
in, a Latin American country; (b) securities of companies that derive 50% or
more of their total revenues from business in Latin America, provided that, in
the Sub-adviser's view, the value of such issuers' securities reflect Latin
American developments to a greater extent than developments elsewhere; (c)
securities issued or guaranteed by the government of a country in Latin America,
its agencies or instrumentalities, or municipalities, or the central bank of
such country; (d) U.S. dollar-denominated securities or securities denominated
in a Latin American currency issued by companies to finance operations in Latin
America; and (e) securities of Latin American issuers, as defined herein, in the
form of depositary shares. For purposes of the foregoing definition, the Fund's
purchases of securities issued by companies outside of Latin America to finance
their Latin American operations will be limited to securities the performance of
which is materially related to such company's Latin American activities.
    
 
In allocating investments among the various Latin American countries, the
Sub-adviser looks principally at the stage of industrialization, potential for
productivity gains through economic deregulation, the impact of financial
liberalization and monetary conditions and the political outlook in each
country. In allocating assets between equity and debt securities, the
Sub-adviser will consider, among other factors: the level and anticipated
direction of interest rates; expected rates of economic growth and corporate
profits growth; changes in Latin American government policy including regulation
governing industry, trade, financial markets, and foreign and domestic
investment; substance and likely development of government finances; and the
condition of the balance of payments and changes in the terms of trade. In
evaluating investments in securities of U.S. issuers, the Sub-adviser will
consider, among other factors, the issuer's Latin American business activities
and the impact that development in Latin America may have on the issuer's
operations and financial condition.
 
   
Certain sectors of the economies of certain Latin American countries are closed
to equity investments by foreigners. Further, due to the absence of securities
markets and publicly owned corporations and due to restrictions on direct
investment by foreign entities in certain Latin American countries, the Fund may
be able to invest in such countries solely or primarily through governmentally
approved investment vehicles or companies. In addition, the portion of the
Fund's assets invested directly in Chile may be less than the portion invested
in other Latin American countries because, at present, capital directly invested
in Chile normally cannot be repatriated for at least one year. As a result, the
Fund currently intends to limit
    
 
                               Prospectus Page 6
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
most of its Chilean investments to indirect investments through American
Depositary Receipts ("ADRs") and established Chilean investment companies, the
shares of which are not subject to repatriation restrictions.
 
   
INVESTMENTS IN DEBT SECURITIES. Under normal circumstances, the Fund may invest
up to 50% of its total assets in debt securities. There is no limitation on the
percentage of its assets that may be invested in debt securities that are rated
below investment grade. Investment in below investment grade debt securities
involves a high degree of risk and can be speculative. These debt securities are
the equivalent of high yield, high risk bonds, commonly known as "junk bonds."
Most debt securities in which the Fund will invest are not rated; if rated, it
is expected that such ratings would be below investment grade. However, the Fund
will not invest in debt securities that are in default in payment as to
principal or interest. See "Risk Factors -- Risks Associated with Debt
Securities."
    
 
   
The Fund may invest in "Brady Bonds," which are debt restructurings that provide
for the exchange of cash and loans for newly issued bonds. Brady Bonds have been
issued by the countries of Albania, Argentina, Brazil, Bulgaria, Costa Rica,
Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria, Panama, Peru,
Philippines, Poland, Uruguay, Venezuela and Vietnam, and are expected to be
issued by other emerging market countries. As of the date of this Prospectus,
the Fund is not aware of the occurrence of any payment defaults on Brady Bonds.
Investors should recognize, however, that Brady Bonds do not have a long payment
history. In addition, Brady Bonds are often rated below investment grade.
    
 
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
 
   
Capital appreciation in debt securities may arise as a result of a favorable
change in relative foreign exchange rates, in relative interest rate levels and/
or in the creditworthiness of issuers. The receipt of income from debt
securities owned by the Fund is incidental to its objective of capital
appreciation.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Fund may invest up to 100% of its assets in
cash (U.S. dollars, foreign currencies, multinational units such as Euros)
and/or high quality debt securities or money market instruments to generate
income to defray its expenses, for temporary defensive purposes and pending
investment in accordance with its investment objective and policies. In
addition, the Fund may be primarily invested in U.S. securities for temporary
defensive purposes or pending investment of the proceeds of sales of new Fund
shares. The Fund may assume a temporary defensive position when, due to
political, market or other factors broadly affecting Latin American markets, the
Sub-adviser determines that opportunities for capital appreciation in those
markets would be significantly limited over an extended period or that investing
in those markets presents undue risk of loss. For a full description of money
market instruments, see "Temporary Defensive Strategies" in the "Investment
Objectives and Policies" section of the Statement of Additional Information.
    
 
   
ADDITIONAL INVESTMENT POLICIES
    
 
   
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Sub-adviser or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940 (the "1940
Act"), the Fund generally may invest up to 10% of its total assets in the
aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
    
 
   
Investment in other investment companies may involve the payment of substantial
premiums above the value of such investment companies' portfolio securities and
is subject to limitations under the 1940 Act and market availability. The Fund
does not intend to invest in such investment companies unless, in the judgment
of the Sub-adviser, the potential benefits of such investment justify the
payment of any applicable premium or sales charge. As a shareholder in an
investment company, the Fund would bear its ratable share of that investment
company's expenses, including its advisory and administration fees. At the same
time the
    
 
                               Prospectus Page 7
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
Fund would continue to pay its own management fees and other expenses. AIM and
the Sub-adviser will waive their advisory fees to the extent that the Fund
invests in an Affiliated Fund.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows a Fund to retain
ownership of the securities loaned and, at the same time, enhances the Fund's
total return. At all times a loan is outstanding, the Fund's borrower must
maintain with the Fund's custodian collateral consisting of cash, U.S.
government securities or certain irrevocable letters of credit equal to the
value of the borrowed securities plus any accrued interest or such other
collateral as permitted by the Fund's investment program and regulatory
agencies, and as approved by the Board. The Fund limits its loans of portfolio
securities to an aggregate of 30% of the value of its total assets, measured at
the time any such loan is made. The risks in lending portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional collateral or in recovery of the loaned securities and possible loss
of rights in the collateral should the borrower fail financially.
    
 
   
PRIVATIZATIONS. The governments in some Latin American countries have been
engaged in programs of selling part or all of their stakes in government owned
or controlled enterprises ("privatizations"). The Sub-adviser believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain Latin American countries, the ability of foreign
entities such as the Fund to participate in privatizations may be limited by
local law, or the terms on which the Fund may be permitted to participate may be
less advantageous than those afforded local investors. There can be no assurance
that Latin American governments and governments in emerging markets will
continue to sell companies currently owned or controlled by them or that
privatization programs will be successful.
    
 
   
BORROWING. It is a fundamental policy of the Fund that it may borrow an amount
up to 33 1/3% of its total assets in order to meet redemption requests.
Borrowing may cause greater fluctuation in the value of the Fund's shares than
would be the case if the Fund did not borrow, but also may enable the Fund to
retain favorable securities positions rather than liquidating such positions to
meet redemptions. It is a nonfundamental policy of the Fund, that the Fund will
not purchase securities during times when outstanding borrowings represent 5% or
more of each Fund's total assets.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian bank and will mark to market daily such assets.
There is a risk that the securities may not be delivered and that the Fund may
incur a loss.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies and options on futures contracts to attempt to
hedge against the overall level of investment risk normally associated with the
portfolio. These instruments are often referred to as "derivatives," which may
be defined as financial instruments whose performance is derived, at least in
part, from the performance of another asset (such as a security, currency or an
index of securities). The Fund may enter into such instruments up to the full
value of its portfolio assets. See "Risk Factors -- Options, Futures and Foreign
Currency Transactions" herein and "Options, Futures and Currency Strategies" in
the Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the
    
 
                               Prospectus Page 8
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
U.S. dollar or may involve two foreign currencies. The Fund may enter into
forward currency contracts either with respect to specific transactions or with
respect to its portfolio positions. The Fund also may purchase and sell put and
call options on currencies, futures contracts on currencies and options on such
futures contracts to hedge against movements in exchange rates.
    
 
   
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most Latin American markets, to
securities denominated in such currencies or to securities of issuers domiciled
or principally engaged in business in such emerging markets. To the extent that
such a market does not exist, the Sub-adviser may not be able to effectively
hedge its investment in such markets.
    
 
   
The Fund may purchase and sell put and call options on securities to hedge
against the risk of fluctuations in the prices of securities held by the Fund or
that the Sub-adviser intends to include in the Fund's portfolio. The Fund also
may purchase and sell put and call options on indices to hedge against overall
fluctuations in the securities markets generally or in a specific market sector.
    
 
   
Further, the Fund may sell stock index futures contracts and may purchase put
options or write call options on such futures contracts to protect against a
general stock market decline or a decline in a specific market sector that could
adversely affect the Fund's portfolio. The Fund also may purchase stock index
futures contracts and purchase call options or write put options on such
contracts to hedge against a general stock market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. The Fund
may use interest rate futures contracts and options thereon to hedge the debt
portion of its portfolios against changes in the general level of interest
rates.
    
 
   
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of the Fund's outstanding voting securities.
A "majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations as
fundamental policies which also may not be changed without shareholder approval.
A complete description of these limitations is included in the Statement of
Additional Information. Unless specifically noted, the Fund's investment
policies described in this Prospectus and in the Statement of Additional
Information may be changed by the Trust's Board of Trustees without shareholder
approval. If a percentage restriction on investment or utilization of assets in
an investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.
    
 
   
The Fund is authorized to engage in Short Sales, although it currently has no
intention of doing so, and may purchase American Depository Receipts, American
Depository Shares, Global Depository Receipts and European Depository Receipts.
See "Short Sales" and "Depository Receipts," respectively, in the "Investment
Objectives and Policies" section of the Statement of Additional Information.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objective. Investing in the Fund entails a substantial degree of risk and an
investment in the Fund should be considered speculative. Investors are strongly
advised to consider carefully the special risks involved in Latin America, which
are in addition to the usual risks of investing in developed markets around the
world.
    
 
   
The Fund's net asset value will fluctuate, reflecting fluctuations in the market
value of its portfolio positions and its net currency exposure. Equity
securities, particularly common stocks, generally represent the most junior
position in an issuer's capital structure and entitle holders to an interest in
the assets of an issuer, if any, remaining after all more senior claims have
been satisfied. The value of equity securities held by the Fund will
    
 
                               Prospectus Page 9
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
fluctuate in response to general market and economic developments, as well as
developments affecting the particular issuers of such securities.
 
   
The Fund is classified under the 1940 Act as a "non-diversified" fund. As a
result, the Fund will be able to invest in a fewer number of issuers than if it
were classified under the 1940 Act as a "diversified" fund. To the extent that
the Fund invests in a smaller number of issuers, the value of its shares may
fluctuate more widely and it may be subject to greater investment and credit
risk with respect to its portfolio.
    
 
   
Investing in securities of Latin American issuers involves risks relating to
potential political and economic instability of certain Latin American countries
and the risks of expropriation, nationalization, confiscation of assets and
property or the imposition of restrictions on foreign investment and on
repatriation of capital invested. In the event of such expropriation,
nationalization or other confiscation, the Fund could lose its entire investment
in any such country.
    
 
The securities markets of Latin American countries are substantially smaller,
less developed, less liquid and more volatile than the major securities markets
in the United States. Disclosure and regulatory standards are in many respects
less stringent than U.S. standards. Furthermore, there is a lower level of
monitoring and regulation of the markets and the activities of investors in such
markets, and enforcement of existing regulations has been extremely limited.
 
The limited size of many Latin American securities markets and limited trading
volume in issuers compared to volume of trading in U.S. securities could cause
prices to be erratic for reasons apart from factors that affect the quality of
the securities. For example, limited market size may cause prices to be unduly
influenced by traders who control large positions. Adverse publicity and
investors' perceptions, whether or not based on fundamental analysis, may
decrease the value and liquidity of portfolio securities, especially in these
markets.
 
   
Further, there is a risk that an emergency situation may arise in one or more
Latin American markets as a result of which prices for portfolio securities in
such markets may not be readily available. Section 22(e) of the 1940 Act permits
a registered investment company, such as the Fund, to suspend redemption of its
shares for any period during which an emergency exists, as determined by the
SEC. Accordingly, when the Fund believes that circumstances dictate, it will
promptly apply to the SEC for a determination that such an emergency exists
within the meaning of Section 22(e) of the 1940 Act. During the period
commencing from the Fund's identification of such conditions until the date of
any SEC action, the Fund's portfolio securities in the affected markets will be
valued at fair value determined in good faith by or under the direction of the
Trust's Board of Trustees.
    
 
   
The economies of individual Latin American countries may differ favorably or
unfavorably from the U.S. economy in such respects as the rate of growth of
gross domestic product, the rate of inflation, capital reinvestment, resource
self-sufficiency and balance of payments position. Most Latin American countries
have experienced substantial, and in some periods extremely high, rates of
inflation for many years. Inflation and rapid fluctuations in inflation rates
have had and may continue to have very negative effects on the economies and
securities markets of certain Latin American countries. Furthermore, certain
Latin American countries may impose withholding taxes on dividends payable to
the Fund at a higher rate than those imposed by other foreign countries. This
may reduce the Fund's investment income available for distribution to
shareholders.
    
 
Companies in Latin America are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from those
applicable to U.S. companies. There is substantially less publicly available
information about Latin American companies and the governments of Latin American
countries than there is about U.S. companies and the U.S. Government.
 
Certain Latin American countries are among the largest debtors to commercial
banks and foreign governments. At times certain Latin American countries have
declared moratoria on the payment of principal and/or interest on external debt.
The Fund may invest in debt securities, including Brady Bonds, issued as part of
debt restructurings and such debt is to be considered speculative. There is a
history of defaults with respect to commercial bank loans by public and private
entities issuing Brady Bonds.
 
   
RISKS ASSOCIATED WITH DEBT SECURITIES. The value of the debt securities held by
the Fund generally will vary inversely with market interest rates. If interest
rates in a market fall, the Fund's debt securities issued by governments or
companies in that market ordinarily will increase in value. If market interest
rates increase, however, the debt securities owned by the Fund in that market
will likely decrease in value.
    
 
                               Prospectus Page 10
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
 
   
The Fund may invest up to 50% of its total assets in debt securities of any
rating. Such investments involve a high degree of risk.
    
 
Debt rated Baa by Moody's Investors Service, Inc. ("Moody's") is considered by
Moody's to have speculative characteristics. Debt rated BB, B, CCC, CC or C by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), and
debt rated Ba, B, Caa, Ca or C by Moody's is regarded, on balance, as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. While such
lower quality debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major risk exposures to adverse
conditions. Debt rated C by Moody's or S&P is the lowest rated debt that is not
in default as to principal or interest and such issues so rated can be regarded
as having extremely poor prospects of ever attaining any real investment
standing. Lower quality debt securities are also generally considered to be
subject to greater risk than securities with higher ratings with regard to a
deterioration of general economic conditions. These foreign debt securities are
the equivalent of high yield, high risk bonds, commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. Similarly, certain Latin American governments that issue lower
quality debt securities are among the largest debtors to commercial banks,
foreign governments and supranational organizations such as the World Bank, and
may not be able or willing to make principal and/ or interest repayments as they
come due. The risk of loss due to default by the issuer is significantly greater
for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
   
Lower quality debt securities frequently have call or buy-back features which
would permit an issuer to call or repurchase the security from the Fund. In
addition, the Fund may have difficulty disposing of lower quality securities
because they may have a thin trading market. There may be no established retail
secondary market for many of these securities, and the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing the Fund's portfolio. The Fund may also acquire lower quality debt
securities during an initial underwriting or which are sold without registration
under applicable securities laws. Such securities involve special considerations
and risks.
    
 
   
In addition to the foregoing, factors that could have an adverse effect on the
market value of lower quality debt securities in which the Fund may invest
include: (i) potential adverse publicity; (ii) heightened sensitivity to general
economic or political conditions; and (iii) the likely adverse impact of a major
economic recession.
    
 
   
The Fund may also incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in Latin American markets can
differ from debt obligations issued by private entities in that remedies from
defaults generally must be pursued in the courts of the defaulting government,
and legal recourse is therefore somewhat diminished. Political conditions, in
terms of a government's willingness to meet the terms of its debt obligations,
also are of considerable significance. There can be no assurance that the
    
 
                               Prospectus Page 11
<PAGE>
                         AIM LATIN AMERICAN GROWTH FUND
   
holders of commercial bank debt may not contest payments to the holders of debt
securities issued by governments in Latin American markets in the event of
default by the governments under commercial bank loan agreements.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 10% of its net assets in
securities for which no readily available market exists, so-called "Illiquid
Securities." The Fund may invest in joint ventures, cooperatives, partnerships
and state enterprises and other similar vehicles which are illiquid
(collectively, "Special Situations"). The Sub-adviser believes that carefully
selected investments in Special Situations could enable the Fund to achieve
capital appreciation substantially exceeding the appreciation the Fund would
realize if it did not make such investments. However, in order to limit
investment risk, the Fund will invest no more than 5% of its total assets in
Special Situations.
    
 
Illiquid securities may be more difficult to value than liquid securities and
the sale of illiquid securities generally will require more time and result in
higher brokerage charges or dealer discounts and other selling expenses than the
sale of liquid securities. Moreover, illiquid securities often sell at a price
lower than similar securities that are liquid.
 
   
CURRENCY RISK. Because the Fund may invest substantially in securities
denominated in currencies other than the U.S. dollar, and since the Fund may
hold foreign currencies, the Fund will be affected favorably or unfavorably by
exchange control regulations or changes in the exchange rates between such
currencies and the U.S. dollar. Changes in currency exchange rates will
influence the value of the Fund's shares, and also may affect the value of
dividends and interest earned by the Fund and gains and losses realized by the
Fund. Currencies generally are evaluated on the basis of fundamental economic
criteria (e.g., relative inflation and interest rate levels and trends, growth
rate forecasts, balance of payments status and economic policies) as well as
technical and political data. Exchange rates are determined by the forces of
supply and demand in the foreign exchange markets. These forces are affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. If the
currency in which a security is denominated appreciates against the U.S. dollar,
the dollar value of the security will increase. Conversely, a decline in the
exchange rate of the currency would adversely affect the value of the security
expressed in dollars.
    
 
   
Many of the currencies of Latin American countries have experienced steady
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries. Any devaluations in the currencies
in which the Fund's portfolio securities are denominated may have a detrimental
impact on the Fund.
    
 
Some countries also may have fixed currencies whose values against the U.S.
dollar are not independently determined. In addition, there is a risk that
certain countries may restrict the free conversion of their currencies into
other currencies. Further, certain currencies may not be internationally traded.
 
   
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. Options, futures and foreign
currency transactions involve certain risks, which include: (1) dependence on
the Sub-adviser's ability to predict movements in the prices of individual
securities, fluctuations in the general securities markets and movements in
interest rates and currency markets; (2) imperfect correlation, or even no
correlation, between movements in the price of forward contracts, options,
futures contracts or options thereon and movements in the price of the currency
or security hedged or used for cover; (3) the fact that skills and techniques
needed to trade options, futures contracts and options thereon or to use forward
currency contracts are different from those needed to select the securities in
which the Fund invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of a Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for the Fund to sell a security at a disadvantageous time, due to
the need for the Fund to maintain "cover" or to set aside securities in
connection with hedging transactions.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust on the one side and persons or companies furnishing services
to the Fund on the other, including the investment management and administration
agreement with AIM, the investment sub-advisory and sub-administration agreement
between AIM and the Sub-adviser, the agreements with AIM Distributors regarding
distribution of the Fund's shares, the custody agreement and the transfer agency
agreement. The day to day operations of the Fund are delegated to the officers
of the Trust, subject always to the objective and policies of the Fund and to
the general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trust's Board of Trustees.
    
 
   
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the Fund's portfolio and
placing orders to buy, sell or hold particular securities; furnishing corporate
officers and clerical staff; providing office space, services and equipment; and
supervising all matters relating to the Fund's operation. For these services,
the Fund pays AIM investment management and administration fees, computed daily
and paid monthly, based on its average daily net assets, at the annualized rate
of .975% on the first $500 million, .95% on the next $500 million, .925% on the
next $500 million, and .90% on amounts thereafter. Out of the aggregate fees
payable by the Fund, AIM pays the Sub-adviser sub-advisory and
sub-administration fees equal to 40% of the aggregate fees AIM receives from the
Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or other agents. AIM has
undertaken to limit the Fund's expenses (exclusive of brokerage commissions,
taxes, interest and extraordinary expenses) to the annual rate of 1.50% of the
average daily net assets of the Fund's Advisor Class shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly-owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
    
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate

In placing securities orders for the Fund's portfolio transactions, the
Sub-adviser seeks to obtain the best net results. Consistent with its obligation
to obtain the best net results, the Sub-adviser may consider a broker/dealer's
sale of shares of the AIM Funds as a factor in considering through whom
portfolio transactions will be effected. Brokerage transactions may be executed
through affiliates of AIM or the Sub-adviser. High portfolio turnover (over
100%) involves correspondingly greater brokerage commissions and other
transaction costs that the Fund will bear directly and could result in the
realization of net capital gains which would be taxable when distributed to
shareholders. See "Dividends, Distributions and Tax Matters."
    
 
   
DISTRIBUTOR. The Trust has entered into a Master Distribution Agreement, dated
May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Adviser Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.
    
 
   
The Distribution Agreement provides AIM Distributors with the exclusive right to
distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland Corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust. From time to time, the Trust may establish other funds, each
corresponding to a distinct investment portfolio and a distinct series of the
Trust's shares of beneficial interest. Shares of each fund are entitled to one
vote per share (with proportional voting for fractional shares) and are freely
transferable. Shareholders

have no preemptive rights. Other than the automatic conversion of Class B shares
to Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that class. The shares of the Fund and the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may issue
an unlimited number of shares of the Fund. Each share of the Fund represents an
interest in the Fund only, has a par value of $0.01 per share, represents an
equal proportionate interest in the Fund with other shares of the fund and is
entitled to such dividends and distributions out of the income earned and gain
realized on the assets belonging to the Fund as may be declared by the Board of
Trustees. Each share of the Fund is equal in earnings, assets and voting
privileges except that each class normally has exclusive voting rights with
respect to its distribution plan and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.

other fiduciaries purchasing shares for employee benefit plans that are
sponsored by organizations that have at least 1,000 employees; (b) any account
with assets of at least $10,000 if (i) a financial planner, trust company, bank
trust department or registered investment adviser has investment discretion over
the account and (ii) the account holder pays such person as compensation for its
advice and other services an annual fee of at least .50% of the assets in the
account; (c) any account with assets of at least $10,000 if (i) the account is
established under a "wrap fee" program and (ii) the account holder pays the
sponsor of such program an annual fee of at least .50% of the assets in the
account; (d) accounts advised by INVESCO (NY), Inc. or one of the companies

    Financial planners, trust companies, bank trust departments and registered

                                      A-2
<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in

<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the

proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.

DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE
OR LOCAL TAX LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES
DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE

ADVISORS BEFORE INVESTING.
 
   
    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.
    
 
   
    AIM DEVELOPING MARKETS FUND, AIM EMERGING MARKETS FUND, AIM EUROPE GROWTH
FUND, AIM GLOBAL CONSUMER PRODUCTS AND SERVICES FUND, AIM GLOBAL FINANCIAL
SERVICES FUND, AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HEALTH CARE FUND, AIM
GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.
    
 
GENERAL INFORMATION
 
    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

                        PROSPECTUS -- SEPTEMBER 8, 1998
- --------------------------------------------------------------------------------
 
   
This Prospectus contains information about AIM Strategic Income Fund (the
"Fund"), which is one of several series investment portfolios comprising AIM
Investment Funds (the "Trust"), an open-end, series, management investment
company. The Fund is a non-diversified portfolio which primarily seeks high
current income and secondarily seeks capital appreciation. The Fund allocates
its assets among debt securities of issuers in: (1) the United States; (2)
developed foreign countries; and (3) emerging markets.
    
 
The Fund is designed for long-term investors and not as a trading vehicle, does
not represent a complete investment program and is not suitable for all
investors. An investment in the Fund involves risk factors that should be
reviewed carefully by potential investors. The Fund is authorized to borrow
money for investment purposes, which would increase the volatility of its
performance and involves additional risks. See "Investment Objectives and
Policies" and "Risk Factors."
 
THE STRATEGIC INCOME FUND INVESTS UP TO 50% OF ITS TOTAL ASSETS IN LOWER QUALITY
AND UNRATED FOREIGN GOVERNMENT BONDS WHOSE CREDIT QUALITY IS GENERALLY
CONSIDERED THE EQUIVALENT OF U.S. CORPORATE DEBT SECURITIES COMMONLY KNOWN AS
"JUNK BONDS." INVESTMENTS OF THIS TYPE ARE SUBJECT TO A GREATER RISK OF LOSS OF
PRINCIPAL AND INTEREST. PURCHASERS SHOULD CAREFULLY ASSESS THE RISKS ASSOCIATED
WITH AN INVESTMENT IN THE FUND. SEE "INVESTMENT OBJECTIVES AND POLICIES" AND
"RISK FACTORS."
 
   
This Prospectus sets forth concisely information about the Fund that prospective
investors should know before investing. It should be read and retained for
future reference. A Statement of Additional Information, dated September 8,
1998, has been filed with the Securities and Exchange Commission ("SEC") and is
incorporated herein by reference. The Statement of Additional Information is

The Fund:                      The Fund is a non-diversified series of the Trust.

                               developed foreign countries; and (3) emerging markets, and selects particular securities in each
                               sector based on their relative investment merit.
 
Investment Managers:           The Fund is managed by A I M Advisors, Inc. ("AIM") and is sub-advised and sub-administered by
                               INVESCO (NY), Inc. (the "Sub-adviser"). AIM and the Sub-adviser and their worldwide asset management

                               of a least $10,000 if (i) such account is established under a "wrap fee" program, and (ii) the
                               account holder pays the sponsor of such program an annual fee of at least 0.50% on the assets in the
                               account; (d) accounts advised by the Sub-adviser or one of the companies formerly affiliated with the
                               Asset Management Division of Liechtenstein Global Trust AG, provided such accounts were invested in
                               Advisor Class shares of any of the funds in The AIM Family of Funds on May 29, 1998; and (e) any of
                               the companies composing or affiliated with AMVESCAP PLC. Pursuant to a separate prospectus, the Fund
                               also offers Class A and Class B shares, which represent interests in the Fund. The Class A and Class
                               B shares have different distribution arrangements.
 
                               Initial investments in Advisor Class shares must be at least $500 and additional investments must be
                               at least $50. The distributor of the Advisor Class shares is A I M Distributors, Inc. ("AIM
                               Distributors"), P.O. Box 4739, Houston, TX 77210-4739. See "How to Purchase Shares."
 
Exchange Privilege:            The Fund is among those mutual funds distributed by AIM Distributors (collectively, "The AIM Family
                               of Funds"). Advisor Class shares of the Fund may be exchanged for Advisor Class shares of certain
                               Funds in the AIM Family of Funds in the manner and subject to the policies and charges set forth
                               herein. See "Exchange Privilege."
 
Redeeming Shares:              Advisor Class shareholders of the Fund may redeem all or a portion of their shares at net asset value
                               on any business day. See "How to Redeem Shares."
 
Distributions:                 The Fund currently declares and pays dividends from net investment income, if any, on a monthly
                               basis. The Fund makes distributions of realized capital gains, if any, on an annual basis. Dividends
                               and distributions of the Fund may be reinvested at net asset value without payment of a sales charge
                               in the Fund's shares or may be invested in shares of the other funds in The AIM Family of Funds. See
                               "Dividends, Distributions and Tax Matters."
 
Risk Factors:                  There is no assurance that the Fund will achieve its investment objectives. The Fund's net asset
                               value will fluctuate, reflecting fluctuations in the market value of its portfolio holdings. The
                               value of debt securities held by the Fund generally fluctuates inversely with interest rate
                               movements.
 
                               The Fund will invest in foreign securities. Investments in foreign securities involve risks relating
                               to political and economic developments abroad and the differences between the regulations to which
                               U.S. and foreign issuers are subject. Individual foreign economies also may differ favorably or
                               unfavorably from the U.S. economy. Changes in foreign currency exchange rates will affect the Fund's
                               net asset value, earnings and gains and losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than those of securities of comparable
                               U.S. companies. The Fund may invest in debt securities of issuers in emerging markets. Such
                               investments entail greater risks than investing in securities of issuers in developed markets.

                               The Fund may engage in certain foreign currency, options and futures transactions to attempt to hedge
                               against the overall level of investment and currency risk associated with its present or planned
                               investments. Such transactions involve certain risks and transaction costs.
 
                               The Fund may invest up to 50% of its total assets in debt securities rated below investment grade or,
                               if not rated, determined by the Sub-adviser to be of comparable quality. Investments of this type are
                               subject to greater risk of loss of principal and interest.

    subject to additional fees charged by such entities or by the sponsors of
    such programs. Where any account advised by one of the companies composing

                              FINANCIAL HIGHLIGHTS
 
- --------------------------------------------------------------------------------
 
   
The table below provides condensed financial information concerning income and
capital changes for one Advisor Class share of the Fund. For the period March
29, 1988 (commencement of operations) to October 22, 1992, the Strategic Income
Fund was named G.T. Global Bond Fund and operated under different investment
objectives, policies and limitations. This information is supplemented by the
financial statements and accompanying notes appearing in the Statement of
Additional Information.
    
 
                           AIM STRATEGIC INCOME FUND
                   (FORMERLY GT GLOBAL STRATEGIC INCOME FUND)
 
                                 [TO BE ADDED]
 
                            ------------------------
 
   
PERFORMANCE. All advertisements of the Fund will disclose the maximum sales
charge (including deferred sales charges) imposed on purchases of the Fund's
shares. If any advertised performance data does not reflect the maximum sales
charge (if any), such advertisement will disclose that the sales charge has not
been deducted in computing the performance data, and that, if reflected, the
maximum sales charge would reduce the performance quoted. See the Statement of
Additional Information for further details concerning performance comparisons
used in advertisements by the Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
    
 
   
The Fund's total return is calculated in accordance with a standardized formula
for computation of annualized total return.
    
 
   
The Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested. A cumulative total return reflects the Fund's performance over a
stated period of time. An average annual total return reflects the hypothetical
compounded annual rate of return that would have produced the same cumulative
total return if the Fund's performance had been constant over the entire period.
BECAUSE AVERAGE ANNUAL RETURNS TEND TO EVEN OUT VARIATIONS IN THE FUND'S RETURN,
INVESTORS SHOULD RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL
YEAR-BY-YEAR RESULTS. To illustrate the components of overall performance, the
Fund may separate its cumulative and average annual returns into income results
and capital gains or losses.
    
 
   
Yield is computed in accordance with standardized formulas described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield reflects investment
income net of expenses over the relevant period attributable to a Fund share,
expressed as an annualized percentage of the net asset value per share for
Advisor Class shares.
    
 
   
Yield is a function of the type and quality of the Fund's investments, the
maturity of the securities held in the Fund's portfolio and the operating
expense ratio of the Fund. A shareholder's investment in the Fund is not insured
or guaranteed. These factors should be carefully considered by the investor
before making an investment in the Fund.
    
 
   
From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of any Fund. Such practices will
have the effect of increasing the Fund's yield and total return. The performance
of the Fund will vary from time to time and past results are not necessarily
representative of future results.

The Fund's performance is a function of its portfolio management in selecting
the type and quality of portfolio securities and is affected by operating
expenses of the Fund as well as by general market conditions.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund primarily seeks high current income and secondarily seeks capital
appreciation. There can be no assurance that the fund will achieve its
investment objective.
    
 
   
The Fund invests in debt securities of issuers in: (1) the United States; (2)
developed foreign countries; and (3) emerging markets. The Fund selects debt
securities from those issued by governments, their agencies and
instrumentalities; central banks; and commercial banks and other corporate
entities. Debt securities in which the Fund may invest include bonds, notes,
debentures, and other similar instruments including mortgage-backed and
asset-backed securities of foreign issuers as well as domestic issuers. The Fund
normally invests at least 50% of its net assets in U.S. and foreign debt and
other fixed income securities that, at the time of purchase, are rated at least
investment grade by Moody's or S&P or, if not rated, determined by the
Sub-adviser to be of comparable quality. No more than 50% of the Fund's total
assets may be invested in securities rated below investment grade. Such
securities involve a high degree of risk and are predominantly speculative. They
are the equivalent of high yield, high risk bonds, commonly known as "junk
bonds." The Fund may also invest in securities that are in default as to payment
of principal and/or interest.
    
 
   
The Fund's investments in emerging market securities may consist substantially
of Brady Bonds (see "General Policies -- Brady Bonds," below) and other
sovereign debt securities issued by emerging market governments that are traded
in the markets of developed countries or groups of developed countries. The
Sub-adviser may invest in debt securities of emerging market issuers that it
determines to be suitable investments for the Fund without regard to ratings.
Currently, the substantial majority of emerging market debt securities are
considered to have a credit quality below investment grade. The Fund also may
invest in below-investment grade debt securities of corporate issuers in the
United States and in developed foreign countries, subject to the overall 50%
limitation.
    
 
   
                                GENERAL POLICIES
    
 
   
ASSET ALLOCATION. The Fund invests in debt obligations allocated among diverse
markets and denominated in various currencies, including U.S. dollars, or in
multinational currency units such as Euros. The Fund is designed for investors
who wish to accept the risks entailed in such investments, which are different
from those associated with a portfolio consisting entirely of securities of U.S.
issuers denominated in U.S. dollars. The Fund may purchase securities that are
issued by the government or a company or financial institution of one country
but denominated in the currency of another country (or a multinational currency
unit).
    
 
   
The Sub-adviser allocates the assets of the Fund in securities of issuers in
countries and in currency denominations where the combination of fixed income
market returns, the price appreciation potential of fixed income securities and
currency exchange rate movements will present opportunities primarily for high
current income and secondarily for capital appreciation. In so doing, the Sub-
adviser intends to take full advantage of the different yield, risk and return
characteristics that investment in the fixed income markets of different
countries can provide for U.S. investors. Fundamental economic strength, credit
quality and currency and interest rate trends are the principal determinants of
the emphasis given to various country, geographic and industry sectors within
the Fund. Securities held by the Fund may be invested in without limitation as
to maturity.
    
 
   
The Sub-adviser selects securities of particular issuers on the basis of its
views as to the best values then currently available in the marketplace. Such
values are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political
    
 
                               Prospectus Page 7

                           AIM STRATEGIC INCOME FUND
   
developments and variations in the supply of funds available for investment in
the world bond market relative to the demands placed upon it.
    
 
   
The Sub-adviser generally evaluates currencies on the basis of fundamental
economic criteria (e.g., relative inflation, interest rate levels and trends,
growth rate forecasts, balance of payments status and economic policies) as well
as technical and political data. The Sub-adviser may seek to protect the Fund
against such negative currency movements through the use of sophisticated
investment techniques. See "Options, Futures and Forward Currency Transactions"
and "Swaps, Caps, Floors and Collars."
    
 
   
According to the Sub-adviser, as of the date of this Prospectus, more than 50%
of the value of all outstanding government debt obligations throughout the world
is represented by obligations denominated in currencies other than the U.S.
dollar. Moreover, from time to time, the debt securities of issuers located
outside the United States have substantially outperformed the debt obligations
of U.S. issuers. Accordingly, the Sub-adviser believes that the Fund's policy of
investing in debt securities throughout the world may enable the achievement of
results superior to those produced by mutual funds with similar objectives to
those of the Fund that invest solely in debt securities of U.S. issuers.
    
 
   
The Fund is designed for investors who wish to accept the risks entailed in such
investments, which are different from those associated with a portfolio
consisting entirely of securities of U.S. issuers denominated in U.S. dollars.
    
 
   
TEMPORARY DEFENSIVE STRATEGIES. The Sub-adviser may employ a temporary defensive
investment strategy if it determines such a strategy to be warranted due to
market, economic or political conditions. Pursuant to such a defensive strategy,
the Fund temporarily may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and/or invest up to 100% of its assets in high
quality debt securities or money market instruments of U.S. or foreign issuers.
In addition, for temporary defensive purposes, most or all of the Fund's
investments may be made in the United States and denominated in U.S. dollars. To
the extent the Fund employs a temporary defensive strategy, it will not be
invested so as to achieve directly its investment objectives. In addition,
pending investment of proceeds from new sales of Fund shares or to meet ordinary
daily cash needs, the Fund may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and may invest in high quality foreign or domestic
money market instruments. For a full description of money market instruments,
see "Selection of Debt Investments" in the "Investment Objectives and Policies"
section of the Statement of Additional Information.
    
 
   
EMERGING MARKET SECURITIES. The Fund considers "emerging markets" to consist of
all countries determined by the Sub-adviser to have developing or emerging
economies and markets. These countries generally include every country in the
world except the United States, Canada, Japan, Australia, New Zealand and most
countries located in Western Europe. The Fund will consider investment in the
following emerging markets:

  Greece          Paraguay       Zimbabwe
</TABLE>
    
 
   
The Fund will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements, overly burdensome repatriation
requirements and similar restrictions, the lack of organized and liquid
securities markets, unacceptable political risks or for other reasons.
    
 
   
As used in this Prospectus and the Statement of Additional Information, an
issuer in an emerging market is an entity: (i) for which the principal
securities trading market is an emerging market, as defined above; (ii) that
(alone or on a consolidated basis) derives 50% or more of its total revenue from
either goods produced, sales made or services performed in emerging markets; or
(iii) organized
    
 
                               Prospectus Page 8
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
under the laws of, or with a principal office in, an emerging market.
    
 
   
BRADY BONDS. The Fund may invest in "Brady Bonds," which are debt restructurings
that provide for the exchange of cash and loans for newly issued bonds. Brady
Bonds have been issued by the countries of Albania, Argentina, Brazil, Bulgaria,
Costa Rica, Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria,
Panama, Peru, Philippines, Poland, Uruguay, Venezuela and Vietnam and are
expected to be issued by other emerging market countries. As of the date of this
Prospectus, the Fund is not aware of the occurrence of any payment defaults on
Brady Bonds. Investors should recognize, however, that Brady Bonds do not have a
long payment history. In addition, Brady Bonds are often rated below investment
grade.
    
 
   
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The Fund may invest in
mortgage-backed and asset-backed securities of U.S. and foreign issuers,
including privately issued mortgage-backed and asset-backed securities.
Mortgage-backed securities represent direct or indirect interests in pools of
underlying mortgage loans that are secured by real property. Investors typically
receive payments out of the interest on and principal of the underlying
mortgages. Asset-backed securities are similar to mortgage-backed securities,
except that the underlying assets are other financial assets or financial
receivables, such as motor vehicle installment sales contracts, home equity
loans, leases of various types of real and personal property, and receivables
from credit cards. Any mortgage-backed and asset-backed securities purchased by
the Fund will be subject to the same rating requirements that apply to its other
investments.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may invest in fixed and floating
rate loans ("Loans") arranged through private negotiations between a foreign
entity and one or more financial institutions ("Lenders"). The majority of the
Fund's investments in Loans in emerging markets is expected to be in the form of
participations in Loans ("Participations") and assignments of portions of Loans
from third parties ("Assignments"). Participations typically will result in the
Fund having a contractual relationship only with the Lender, not with the
borrower government. The Fund will have the right to receive payments of
principal, interest and any fees to which it is entitled only from the Lender
selling the Participation and only upon receipt by the Lender of the payments
from the borrower. In connection with purchasing Participations, the Fund
generally will have no right to enforce compliance by the borrower with the
terms of the loan agreement relating to the loan ("Loan Agreement"), nor any
rights of set-off against the borrower, and the Fund may not directly benefit
from any collateral supporting the Loan in which it has purchased the
Participation. As a result, the Fund will assume the credit risk of both the
borrower and the Lender that is selling the Participation.
    
 
   
In the event of the insolvency of the Lender selling a Participation, the Fund
may be treated as a general creditor of the Lender and may not benefit from any
set-off between the Lender and the borrower. The Fund will acquire
Participations only if the Lender interpositioned between the Fund and the
borrower is determined by the Sub-adviser to be creditworthy. When the Fund
purchases Assignments from Lenders, the Fund will acquire direct rights against
the borrower on the Loan. However, since Assignments are arranged through
private negotiations between potential assignees and assignors, the rights and
obligations acquired by the Fund as the purchaser of an Assignment may differ
from, and be more limited than, those held by the assigning Lender.
    
 
   
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of
    
 
                               Prospectus Page 9
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
actually receiving or delivering the securities, as the case may be. No income
accrues on securities that have been purchased pursuant to a forward commitment
or on a when-issued basis prior to delivery of the securities. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, the Fund will segregate cash or liquid
securities equal to the value of the when-issued or forward commitment
securities with its custodian and will mark to market daily such assets. There
is a risk that the securities may not be delivered and that the Fund may incur a
loss.
    
 
   
The Fund may also sell securities on a "when, as and if issued" basis for
hedging purposes. Under such a transaction, the Fund is required to deliver at a
future date a security it does not presently hold, but which it has a right to
receive if the security is issued. Issuance of the security may not occur, in
which case the Fund would have no obligation to the other party, and would not
receive payment for the sale. Selling securities on a "when, as and if issued"
basis may reduce risk of loss to the extent that such a sale wholly or partially
offsets unfavorable price movements on the investments being hedged. However,
such sales also limit the amount the Fund can receive if the "when, as and if
issued" security is in fact issued.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund is
authorized to borrow money from banks in an amount up to 33 1/3% of its total
assets (including the amount borrowed), less all liabilities and indebtedness
other than the borrowings and may use the proceeds of such borrowings for
investment purposes. The Fund will borrow for investment purposes only when the
Sub-adviser believes that such borrowings will benefit the Fund after taking
into account considerations such as the costs of the borrowing and the likely
investment returns on the securities purchased with the borrowed monies.
    
 
   
Borrowing for investment purposes is known as leveraging, which is a speculative
practice. Such borrowing by the Fund creates the opportunity for increased net
income and appreciation but, at the same time, involves special risk
considerations. For example, leveraging might exaggerate changes in the net
asset value of Fund shares and in the yield realized by the Fund. Although the
principal amount of such borrowings will be fixed, the Fund's assets may change
in value during the time the borrowing is outstanding. By leveraging the Fund,
changes in net asset values, higher or lower, may be greater in degree than if
leverage was not employed. To the extent the income derived from the assets
obtained with borrowed funds exceeds the interest and other expenses that the
Fund will have to pay, the Fund's net income will be greater than if borrowing
was not used. Conversely, if the income from the assets obtained with borrowed
funds is not sufficient to cover the cost of borrowing, the net income of the
Fund will be less than if borrowing were not used, and therefore the amount
available for distribution to shareholders as dividends will be reduced. The
Fund expects that some of its borrowings may be made on a secured basis.
    
 
   
In addition to the foregoing borrowings, the Fund may borrow money for temporary
or emergency purposes or payments in an amount not exceeding 5% of the value of
its total assets (not including the amount borrowed) provided that the total
amount borrowed by the Fund for any purpose does not exceed 33 1/3% of its total
assets.
    
 
   
The Fund may also enter into reverse repurchase agreements with a bank or
recognized securities dealer, although the Fund currently has no intention of
doing so with respect to more than 5% of its total assets. Under a reverse
repurchase agreement, the Fund would sell securities and agree to repurchase
them at a particular price at a future date. At the time the Fund enters into a
reverse repurchase agreement, it will establish and maintain a segregated
account with an approved custodian containing cash or liquid securities having a
value not less than the repurchase price, including accrued interest. Reverse
repurchase agreements involve the risk that the market value of the securities
retained in lieu of sale by the Fund may decline below the price of the
securities the Fund has sold but is obligated to repurchase. In the event the
buyer of securities under a reverse repurchase agreement files for bankruptcy or
becomes insolvent, such buyer or its trustee or receiver may receive an
extension of time to determine whether to enforce the Fund's obligation to
repurchase the securities, and the Fund's use of the proceeds of the reverse
repurchase agreement may effectively be restricted pending such decision.
    
 
   
The Fund also may enter into "dollar rolls," in which the Fund sells fixed
income securities for delivery in the current month and simultaneously contracts
to repurchase substantially similar (same type, coupon and maturity) securities
on a specified future date. During the roll period, the Fund would
    
 
                               Prospectus Page 10
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
forego principal and interest paid on such securities. The Fund would be
compensated by the difference between the current sales price and the forward
price for the future purchase, as well as by the interest earned on the cash
proceeds of the initial sale. See "Investment Objectives and Policies" in the
Statement of Additional Information.
    
 
   
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Fund's assets for purposes of calculating compliance
with the Fund's borrowing limitation. See "Investment Limitations" in the
Statement of Additional Information.
    
 
   
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. At all times a loan is outstanding, the Fund requires the
borrower to maintain with the Fund's custodian, collateral consisting of cash,
U.S. government securities, or certain irrevocable letters of credit equal to at
least the value of the borrowed securities, plus any accrued interest or such
other collateral as permitted by the Fund's investment program and regulatory
agencies, and as approved by the Board. The Fund limits its loans of portfolio
securities to an aggregate of 30% of the value of its total assets, measured at
the time any such loan is made. The risks in lending portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional collateral or in recovery of the loaned securities and possible loss
of rights in the collateral should the borrower fail financially.
    
 
   
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. It also may invest in zero
coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
interest in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the "interest" on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
must be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
    
 
   
SYNTHETIC SECURITY POSITIONS. The Fund may utilize combinations of futures on
bonds and forward currency contracts to create investment positions that have
substantially the same characteristics as bonds of the same type as those on
which the futures contracts are written. Investment positions of this type are
generally referred to as "synthetic securities."
    
 
   
For example, in order to establish a synthetic security position for the Fund
that is comparable to owning a Japanese government bond, the Sub-adviser might
purchase futures contracts on Japanese government bonds in the desired principal
amount and purchase forward currency contracts for Japanese Yen in an amount
equal to the then current purchase price for such bonds in the Japanese cash
market, with each contract having approximately the same delivery date.
    
 
   
The Sub-adviser might roll over the futures and forward currency contract
positions before taking delivery in order to continue the Fund's investment
position, or the Sub-adviser might close out those positions, thus effectively
selling the synthetic security. Further, the amount of each contract might be
adjusted in response to market conditions and the forward currency contract
might be changed in amount or eliminated in order to hedge against currency
fluctuations.
    
 
   
The Sub-adviser would create synthetic security positions for the Fund when it
believes that it can obtain a better yield or achieve cost savings in comparison
to purchasing actual bonds or when comparable bonds are not readily available in
the market. Synthetic security positions are subject to the risk that changes in
the value of purchased futures contracts may differ from changes in the value of
the bonds that might otherwise have been purchased in the cash market. Also,
while the Sub-adviser believes that the cost of creating synthetic security
positions generally will be materially lower
    
 
                               Prospectus Page 11
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
than the cost of acquiring comparable bonds in the cash market, the Fund will
incur transaction costs in connection with each purchase of a futures or forward
currency contract. The use of futures contracts and forward currency contracts
to create synthetic security positions also is subject to substantially the same
risks as those that exist when these instruments are used in connection with
hedging strategies. See "Options, Futures and Forward Currency Transactions"
below and "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Fund may use forward
currency contracts, futures contracts, options on securities, options on
indices, options on currencies, and options on futures contracts to attempt to
hedge against the overall level of investment and currency risk normally
associated with the Fund's investment. The Fund also may enter into interest
rate, currency and index swaps and purchase or sell related caps, floors and
collars and other similar instruments. See "Swaps, Caps, Floors and Collars"
below. These instruments are often referred to as "derivatives," which may be
defined as financial instruments whose performance is derived, at least in part,
from the performance of another asset (such as a security, currency or an index
of securities). The Fund may enter into such instruments up to the full value of
its portfolio assets. See "Risk Factors -- Options, Futures and Currency
Transactions" herein and "Options, Futures and Currency Strategies" in the
Statement of Additional Information.
    
 
   
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund also may purchase and sell put and call
options on currencies, futures contracts on currencies and options on such
futures contracts to hedge against movements in exchange rates.
    
 
   
In addition, the Fund may purchase and sell put and call options on securities
to hedge against the risk of fluctuations in the prices of securities held by
the Fund or that the Sub-adviser intends to include in the Fund's portfolio. The
Fund also may purchase and sell put and call options on indices to hedge against
overall fluctuations in the securities markets generally or in a specific market
sector.
    
 
   
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or market sector decline that could adversely affect the Fund's
portfolio. The Fund also may purchase index futures contracts and purchase call
options or write put options on such contracts to hedge against a general market
or market sector advance and thereby attempt to lessen the cost of future
securities acquisitions. The Fund may use interest rate futures contracts and
options thereon to hedge its portfolio against changes in the general level of
interest rates.
    
 
   
SWAPS, CAPS, FLOORS AND COLLARS. The Fund may enter into interest rate, currency
and index swaps, and purchase or sell related caps, floors and collars and other
derivative instruments. The Fund expects to enter into these transactions
primarily to preserve a return or spread on a particular investment or portion
of its portfolio, to protect against currency fluctuations, as a technique for
managing the portfolio's duration (I.E., the price sensitivity to changes in
interest rates) or to protect against any increase in the price of securities
the Fund anticipates purchasing at a later date. The Fund intends to use these
transactions as hedges, and will not sell interest rate caps or floors if it
does not own securities or other instruments providing an income stream roughly
equivalent to what the Fund may be obligated to pay.
    
 
   
Interest rate swaps involve the exchange by the Fund with another party of their
respective commitments to pay or receive interest (for example, an exchange of
floating rate payments for fixed rate payments) with respect to a notional
amount of principal. A currency swap is an agreement to exchange cash flows on a
notional amount based on changes in the values of the reference indices.
    
 
   
The purchase of a cap entitles the purchaser to receive payments on a notional
principal amount from the party selling the cap to the extent that a specified
index exceeds a predetermined interest rate. The purchase of an interest rate
floor entitles the purchaser to receive payments on a notional principal amount
from the party selling the floor to the extent that a specified index falls
below a predetermined interest rate or amount. A collar is a combination of a
cap and a floor that preserves a certain return within a predetermined range of
interest rates or values.

INDEXED COMMERCIAL PAPER. The Fund may invest without limitation in commercial
paper which is indexed to certain specific foreign currency exchange rates. The
terms of such commercial paper provide that its principal amount is adjusted
upwards or downwards (but not below zero) at maturity to reflect changes in the
exchange rate between two currencies while the obligation is outstanding. The
Fund will purchase such commercial paper with the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency, but the amount of principal payable by the issuer at
maturity will change in proportion to the change (if any) in the exchange rate
between the two specified currencies between the date the instrument is issued
and the date the instrument matures. While such commercial paper entails the
risk of loss of principal, the potential for realizing gains as a result of
changes in foreign currency exchange rates enables the Fund to hedge against a
decline in the U.S. dollar value of investments denominated in foreign
currencies while seeking to provide an attractive money market rate of return.
The Fund will not purchase such commercial paper for speculation.
    
 
   
OTHER INDEXED SECURITIES. The Fund may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of other
securities, securities indices, currencies, precious metals or other
commodities, or other financial indicators. Indexed securities typically, but
not always, are debt securities or deposits whose value at maturity or coupon
rate is determined by reference to a specific instrument or statistic. The
performance of indexed securities depends to a great extent on the performance
of the security, currency, or other instrument to which they are indexed, and
may also be influenced by interest rate changes in the United States and abroad.
At the same time, indexed securities are subject to the credit risks associated
with the issuer of the security, and their values may decline substantially if
the issuer's creditworthiness deteriorates. Indexed securities may be more
volatile than the underlying instruments. New forms of indexed securities
continue to be developed. The Fund may invest in such securities to the extent
consistent with its investment objectives.
    
 
   
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. The
Fund's other investment policies described herein and in the Statement of
Additional Information may be changed by the Trust Board of Trustees without
shareholder approval.
    
 
   
The Fund is authorized to make short sales of securities, although it has no
current intention of doing so. See "Investment Objectives and Policies -- Short
Sales" in the Statement of Additional Information.
    
 
   
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Fund's investment policies or restrictions.

                                  RISK FACTORS
    
 
- --------------------------------------------------------------------------------
 
   
GENERAL. There is no assurance that the Fund will achieve its investment
objectives. The Fund's net asset value will fluctuate, reflecting fluctuations
in the market value of its portfolio positions and its net currency exposure.
The value of fixed income securities held by the Fund generally fluctuates
inversely with interest rate movements. Longer term bonds held by the Fund are
subject to greater interest rate risk.
    
 
   
NON-DIVERSIFIED CLASSIFICATION. The Fund is classified under the Investment
Company Act of 1940 (the "1940 Act") as a "non-diversified" fund. As a result,
the Fund will be able to invest in a fewer number of issuers than if it were
classified under the 1940 Act as a "diversified" fund. To the extent that the
Fund invests in a smaller number of issuers, the value of the Fund's shares may
fluctuate more widely and the Fund may be subject to greater investment and
credit risk with respect to its portfolios.
    
 
   
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies. In addition, certain costs
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Fund's interest and dividends from foreign
issuers may be subject to non-U.S. withholding taxes, thereby reducing their net
investment income.
    
 
   
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect the investments of the Fund in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, rate of savings and capital reinvestment, resource self-sufficiency
and balance of payments positions.
    
 
   
CURRENCY RISK. Since the Fund normally invests substantially in securities
denominated in currencies other than the U.S. dollar, and because they may hold
foreign currencies, they will be affected favorably or unfavorably by exchange
control regulations or changes in the exchange rates between such currencies and
the U.S. dollar. Changes in currency exchange rates will influence the value of
the Fund's shares, and also may affect the value of dividends and interest
earned by the Fund and gains and losses realized by the Fund. Currencies
generally are evaluated on the basis of fundamental economic criteria (e.g.,
relative inflation and interest rate levels and trends, growth rate forecasts,
balance of payments status and economic policies) as well as technical and
political data. The exchange rates between the U.S. dollar and other currencies
are determined by supply and demand in the currency exchange markets, the
international balance of payments, governmental intervention, speculation and
other economic and political conditions. If the currency in which a security is
denominated appreciates against the U.S. dollar, the dollar value of the
security will increase. Conversely, a decline in the exchange rate of the
currency would adversely affect the value of the security expressed in U.S.
dollars.
    
 
   
In addition, many of the currencies in emerging market countries have
experienced steady devaluations relative to the U.S. dollar and major
devaluations have historically occurred in certain countries.
    
 
   
INVESTING IN EMERGING MARKETS. Because of the special risks associated with
investing in emerging markets, an investment in the Fund should be considered
speculative. Investors are strongly advised to consider carefully the special
risks involved in emerging markets, which are in addition to the usual risks of
investing in developed foreign markets around the world.
    
 
                               Prospectus Page 14
<PAGE>
                           AIM STRATEGIC INCOME FUND
 
   
Investing in emerging markets involves risks relating to potential political and
economic instability within such markets and the risks of expropriation,
nationalization, confiscation of assets and property or the imposition of
restrictions on foreign investment and on repatriation of capital invested. In
the event of such expropriation, nationalization or other confiscation in any
emerging market, the Fund could lose its entire investment in that market.
    
 
   
Many emerging market countries have experienced substantial, and in some periods
extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain emerging market
countries.
    
 
   
Economies in emerging markets generally are dependent heavily upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values and other protectionist measures imposed or negotiated by the countries
with which they trade. These economies also have been and may continue to be
affected adversely by economic conditions in the countries in which they trade.
    
 
   
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
United States and other more developed countries. Disclosure and regulatory
standards in many respects are less stringent than in the United States and
other major markets. There also may be a lower level of monitoring and
regulation of emerging securities markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
    
 
   
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Fund to make intended securities purchases due to settlement
problems could cause the Fund to forego attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems could
result in losses to the Fund due to subsequent declines in value of the
portfolio security or, if the Fund has entered into a contract to sell the
security, could result in possible liability to the purchaser.
    
 
   
The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading of securities may cease or may be
substantially curtailed and prices for the Fund's portfolio securities in such
markets may not be readily available. Section 22(e) of the 1940 Act permits a
registered investment company to suspend redemption of its shares for any period
during which an emergency exists, as determined by the SEC. Accordingly, when
the Fund believes that appropriate circumstances warrant, it will promptly apply
to the SEC for a determination that an emergency exists within the meaning of
Section 22(e) of the 1940 Act. During the period commencing from the Fund's
identification of such conditions until the date of SEC action, the portfolio
securities of the Fund in the affected markets will be valued at fair value as
determined in good faith by or under the direction of the Trust's Board of
Trustees.
    
 
   
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The yield characteristics of
mortgage-backed and asset-backed securities differ from those of traditional
bonds. Among the major differences are that interest and principal payments are
made more frequently (usually monthly) and that principal may be prepaid at any
time because the underlying mortgage loans or other assets generally may be
prepaid at any time. Generally, prepayments on fixed-rate mortgage loans will
increase during a period of falling interest rates and decrease during a period
of rising interest rates. Mortgage-backed and asset-backed securities may also
decrease in value as a result of increasing market interest rates and, because
of prepayments, may benefit less than other bonds from declining interest rates.
Reinvestments of prepayments may occur at lower interest rates than the original
investment, thus adversely affecting the yield of the Fund. Actual prepayment
experience may cause the yield of a mortgage-backed security to differ from what
was assumed when the Fund purchased the security. The market for privately
issued mortgage-backed and asset-backed securities is smaller and less liquid
than the market for U.S. government mortgage-backed securities.
    
 
   
Foreign mortgage-backed securities markets are substantially smaller than U.S.
markets, but have been established in several countries, including Germany,
Denmark, Sweden, Canada and Australia,
    
 
                               Prospectus Page 15
<PAGE>
                           AIM STRATEGIC INCOME FUND
   
and may be developed elsewhere. Foreign mortgage-backed securities generally are
structured similar to domestic mortgage-backed securities, and they normally
present substantially similar investment risks as well as the other risks
normally associated with foreign securities.
    
 
   
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may have difficulty disposing of
Assignments and Participations. The liquidity of such securities is limited and,
the Fund anticipates that such securities could be sold only to a limited number
of institutional investors. The lack of a liquid secondary market could have an
adverse impact on the value of such securities and on the Fund's ability to
dispose of particular Assignments or Participations when necessary to meet the
Fund's liquidity needs or in response to a specific economic event, such as a
deterioration in the creditworthiness of the borrower. The lack of a liquid
secondary market for Assignments and Participations also may make it more
difficult for the Fund to assign a value to those securities for purposes of
valuing the Fund's portfolio and calculating its net asset value.
    
 
   
SOVEREIGN DEBT. The Fund may invest in sovereign debt securities of emerging
market governments, including Brady Bonds. Investments in such securities
involve special risks. The issuer of the debt or the governmental authorities
that control the repayment of the debt may be unable or unwilling to repay
principal or interest when due in accordance with the terms of such debt.
Periods of economic uncertainty may result in the volatility of market prices of
sovereign debt obligations and in turn the Fund's net asset value, to a greater
extent than the volatility inherent in domestic fixed income securities.
    
 
   
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
    
 
   
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's investments.
Emerging markets are faced with social and political issues and some of them
have experienced high rates of inflation in recent years and have extensive
internal debt. Among other effects, high inflation and internal debt service
requirements may adversely affect the cost and availability of future domestic
sovereign borrowing to finance governmental programs, and may have other adverse
social, political and economic consequences. Political changes or a
deterioration of a country's domestic economy or balance of trade may affect the
willingness of countries to service their sovereign debt. Although the
Sub-adviser intends to manage the Fund in a manner that will minimize the
exposure to such risks, there can be no assurance that adverse political changes
will not cause the Fund to suffer a loss of interest or principal on any of its
holdings.
    
 
   
In recent years, some of the emerging market countries in which the Fund expects
to invest have encountered difficulties in servicing their sovereign debt
obligations. Some of these countries have withheld payments of interest and/or
principal of sovereign debt. These difficulties have also led to agreements to
restructure external debt obligations -- in particular, commercial bank loans,
typically by rescheduling principal payments, reducing interest rates and
extending new credits to finance interest payments on existing debt. In the
future, holders of emerging market sovereign debt securities may be requested to
participate in similar rescheduling of such debt. Certain emerging market
countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by
    
 
                               Prospectus Page 16

                           AIM STRATEGIC INCOME FUND
   
which a creditor may collect in whole or in part sovereign debt on which an
emerging market government has defaulted.
    
 
   
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
    
 
   
Investors should also be aware that certain sovereign debt instruments in which
the Fund may invest involve great risk. As noted above, sovereign debt
obligations issued by emerging market governments generally are deemed to be the
equivalent in terms of quality to securities rated below investment grade by
Moody's and S&P. Such securities are regarded as predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligations and involve major risk exposure to
adverse conditions. Some of such securities, with respect to which the issuer
currently may not be paying interest or may be in payment default, may be
comparable to securities rated D by S&P or C by Moody's. The Fund may have
difficulty disposing of and valuing certain sovereign debt obligations because
there may be a limited trading market for such securities. Because there is no
liquid secondary market for many of these securities, the Fund anticipates that
such securities could be sold only to a limited number of dealers or
institutional investors.
    
 
   
LOWER QUALITY DEBT SECURITIES. Under normal market conditions the Fund may
invest up to 50% of its total assets in debt securities rated below investment
grade. Such investments involve a high degree of risk.
    
 
   
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest quality debt that is not in default as to
principal or interest and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than higher quality securities with regard to a deterioration of general
economic conditions. These securities are the equivalent of high yield, high
risk bonds, commonly known as "junk bonds." As noted above, the Fund may invest
in debt securities rated below C, which are in default as to principal and/or
interest.
    
 
   
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit quality in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Appendix A" for a discussion of Moody's and S&P's ratings.
    
 
   
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. In addition, lower quality debt securities tend to be more
sensitive to economic conditions and generally have more volatile prices than
higher quality securities. Issuers of lower quality securities are often highly
leveraged and may not have available to them more traditional methods of
financing. For example, during an economic downturn or a sustained period of
rising interest rates, highly leveraged issuers of lower quality securities may
experience financial stress. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations may also be adversely affected by
specific developments affecting the issuer, such as the issuer's inability to
meet specific projected business forecasts or the unavailability of additional
financing. The risk of loss due to default by the issuer is significantly
greater for the holders of lower quality securities because such securities are
generally unsecured and may be subordinated to the claims of other creditors of
the issuer.
    
 
                               Prospectus Page 17

                           AIM STRATEGIC INCOME FUND
 
   
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Fund. If an issuer exercises these provisions in a declining
interest rate market, the Fund may have to replace the security with a lower
yielding security, resulting in a decreased return for investors. In addition,
the Fund may have difficulty disposing of lower quality securities because there
may be a thin trading market for such securities. There may be no established
retail secondary market for many of these securities, and the Fund anticipates
that such securities could be sold only to a limited number of dealers or
institutional investors. The lack of a liquid secondary market also may have an
adverse impact on market prices of such instruments and may make it more
difficult for the Fund to obtain accurate market quotations for purposes of
valuing the securities in the portfolios of the Fund. Adverse publicity and
investor perceptions, whether or not based on fundamental analysis, may also
decrease the values and liquidity of lower quality securities, especially in a
thinly traded market. The Fund also may acquire lower quality debt securities
during an initial underwriting or may acquire lower quality debt securities
which are sold without registration under applicable securities laws. Such
securities involve special considerations and risks.
    
 
   
Factors having an adverse effect on the market value of lower rated securities
or their equivalents purchased by the Fund will adversely impact net asset value
of the Fund. See "Risk Factors" in the Statement of Additional Information. In
addition to the foregoing, such factors may include: (i) potential adverse
publicity; (ii) heightened sensitivity to general economic or political
conditions; and (iii) the likely adverse impact of a major economic recession.
The Fund also may incur additional expenses to the extent it is required to seek
recovery upon a default in the payment of principal or interest on its portfolio
holdings, and the Fund may have limited legal recourse in the event of a
default. Debt securities issued by governments in emerging markets can differ
from debt obligations issued by private entities in that remedies from defaults
generally must be pursued in the courts of the defaulting government, and legal
recourse is therefore somewhat diminished. Political conditions, in terms of a
government's willingness to meet the terms of its debt obligations, also are of
considerable significance. There can be no assurance that the holders of
commercial bank debt may not contest payments to the holders of debt securities
issued by governments in emerging markets in the event of default by the
governments under commercial bank loan agreements.
    
 
   
As of October 31, 1997, the Fund had 89.27% of its total net assets in debt
securities that received a rating from Moody's and 4.00% of its total net assets
in debt securities that were not so rated. In addition, the Fund had 6.73% of
its total net assets in cash and net receivables. The Fund had the following
percentages of its total net assets invested in rated securities: Aaa -- 41.23%,
Aa -- 12.68%, A -- 1.31%, Baa -- 3.75%, Ba -- 24.30%, B -- 6.00%, Caa -- 0.00%,
Ca -- 0.00%, C -- 0.00%. Included under the unrated category are securities held
by the Fund which, while unrated, have been determined by the Sub-adviser to be
of comparable quality to securities in the following rating categories: Ba --
1.03%; and B -- 2.97%. It should be noted that the allocation of the investments
of the Fund by rating on any given date will vary and should not be considered
representative of the future portfolio composition of the Fund.
    
 
   
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although the Fund is
authorized to enter into options, futures and forward currency transactions, the
Fund might not enter into any such transactions. In addition, issuers in
emerging markets typically are subject to a greater degree of change in earnings
and business prospects than issuers in developed countries. Options, futures and
foreign currency transactions involve certain risks, which include: (1)
dependence on the Sub-adviser's ability to predict movements in the prices of
individual securities, fluctuations in the general securities markets or in the
appropriate market sector and movements in interest rates and currency markets;
(2) imperfect correlation, or even no correlation, between movements in the
price of options, forward contracts, futures contracts or options thereon and
movements in the price of the currency or security hedged or used for cover; (3)
the fact that skills and techniques needed to trade options, futures contracts
and options thereon or to use forward currency contracts are different from
those needed to select the securities in which the Fund invests; (4) lack of
assurance that a liquid secondary market will exist for any particular option,
futures contract or option thereon at any particular time; (5) the possible loss
of principal under certain conditions; and (6) the possible inability of the
Fund to purchase or sell a portfolio security at a time when it would otherwise
be favorable for it to do so, or the possible need for the Fund to sell a
security at a disadvantageous

time, due to the need for the Fund or Portfolio to maintain "cover" or to set
aside securities in connection with hedging transactions.
    
 
   
ILLIQUID SECURITIES. The Fund may invest up to 15% of its net assets, in
securities for which no readily available market exists, so-called "illiquid
securities." Illiquid securities may be more difficult to value than liquid
securities and the sale of illiquid securities generally will require more time
and result in higher brokerage charges or dealer discounts and other selling
expenses than the sale of liquid securities. Moreover, illiquid securities often
sell at a price lower than similar securities that are liquid.

- --------------------------------------------------------------------------------
 
   
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund. The Trust's Board of Trustees has approved all significant agreements
between the Trust and persons or companies furnishing services to the Fund
including the investment management and administration agreement with AIM, the
investment sub-advisory and sub-administration agreement between AIM and the
Sub-adviser, the agreements with AIM Distributors regarding distribution of the
Fund's shares, the custody agreement and the transfer agency agreement. The
day-to-day operations of the Fund are delegated to the officers of the Trust,
subject always to the investment objectives and policies of the Fund and to the
general supervision of the Trust's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the Trustees of the Trust.
    
 
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by AIM and the
Sub-adviser as the Fund's investment managers and administrators include, but
are not limited to, determining the composition of the investment portfolio of
the Fund and placing orders to buy, sell or hold particular securities. In
addition, AIM and the Sub-adviser provide the following administration services
to the Fund: furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Fund's operation.
 
   
The Fund pays AIM investment management and administration fees computed daily
and payable monthly, based on the average daily net assets, for such services at
the annualized rate of .725% on the first $500 million, .70% on the next $1
billion, .675% on the next $1 billion, and .65% on amounts thereafter. Out of
the aggregate fees payable by the Fund, AIM pays the Sub-adviser sub-advisory
and sub-administration fees equal to 40% of the aggregate fees AIM receives from
the Fund. The investment management and administration fees paid by the Fund are
higher than those paid by most mutual funds. The Fund pays all expenses not
assumed by AIM, the Sub-adviser, AIM Distributors or any other agents. AIM has
undertaken to limit the expenses of the Advisor Class shares of the Fund
(exclusive of brokerage commissions, taxes, interest and extraordinary expenses)
to the maximum annual rate of 1.50% of the average daily net assets of the
Fund's Advisor Class shares.
    
 
   
The Sub-adviser also serves as the Fund's pricing and accounting agent. For
these services the Sub-adviser receives a fee consisting of 0.03% of the first
$5 billion of assets, and 0.02% of the assets in excess of $5 billion, of the
AIM Funds that are sub-advised by the Sub-adviser (other than AIM Eastern Europe
Fund). Each of these funds, including the Fund, pays an amount based upon its
relative net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment manager to the Fund pursuant to a master investment management and
administration agreement, dated as of May 29, 1998 (the "Advisory Agreement").
AIM was organized in 1976 and, together with its subsidiaries, manages or
advises approximately 90 investment company portfolios encompassing a broad
range of investment objectives. The Sub-adviser, 50 California Street, 27th
Floor, San Francisco, California 94111, and 1166 Avenue of the Americas, New
York, New York 10036, serves as the sub-adviser to the Fund pursuant to an
investment sub-advisory and sub-administration agreement dated as of May 29,
1998. Prior to May 29, 1998, the Sub-adviser was known as Chancellor LGT Asset
Management, Inc. On May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the

former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired LGT's Asset
Management Division, which included the Sub-adviser and certain other
affiliates. As a result of this transaction, the Sub-adviser is now an indirect
wholly owned subsidiary of AMVESCAP PLC. Prior to the sale, the Sub-adviser and
its worldwide asset management affiliates provided investment management and/or
administrative services to institutional, corporate and individual clients
around the world since 1969.
 
AIM and the Sub-adviser and their worldwide asset management affiliates provide
investment management and/or administrative services to institutional, corporate
and individual clients around the world. AIM and the Sub-adviser are both
indirect wholly owned subsidiaries of AMVESCAP PLC. AMVESCAP PLC and its
subsidiaries are an independent investment management group that has a
significant presence in the institutional and retail segment of the investment
management industry in North America and Europe, and a growing presence in Asia.
 
In addition to the investment resources of their Houston, San Francisco and New
York offices, AIM and the Sub-adviser draw upon the expertise, personnel, data
and systems of other offices, including investment offices in Atlanta, Boston,
Dallas, Denver, Louisville, Miami, Portland (Oregon), Frankfurt, Hong Kong,
London, Singapore, Sydney, Tokyo and Toronto. In managing the Fund, the
Sub-adviser employs a team approach, taking advantage of its investment
resources around the world.

In placing orders for the Fund's securities transactions, the Sub-adviser seeks
to obtain the best net results. Consistent with its obligation to obtain the
best net results, the Sub-adviser may consider a broker/dealer's sale of shares
of the AIM Funds as a factor in considering through whom portfolio transactions
will be effected. Brokerage transactions for the Fund may be executed through
affiliates of AIM or the Sub-adviser. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders. See
"Dividends, Distributions and Tax Matters."

May 29, 1998 (the "Distribution Agreement"), with AIM Distributors, a registered
broker-dealer and a wholly owned subsidiary of AIM, to act as the distributor of
the Advisor Class shares of the Fund. Certain Trustees and officers of the Trust
are affiliated with AIM Distributors.

distribute Advisor Class shares of the Fund directly and through institutions
with whom AIM Distributors has entered into selected dealer agreements.

                               OTHER INFORMATION
    
 
- --------------------------------------------------------------------------------
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Delaware business trust
on May 7, 1998. On September 4, 1998, the Trust acquired the assets of and
assumed the liabilities of AIM Investment Funds, Inc., a Maryland corporation.
The Fund constitutes one of the thirteen separate and distinct series portfolios
of the Trust.
    
 
   
From time to time, the Trust may establish other funds, each corresponding to a
distinct investment portfolio and a distinct series of the Trust's shares.
Shares of each fund are entitled to one vote per share (with proportional voting
for fractional shares) and are freely transferable. Shareholders have no
preemptive rights. Other than the automatic conversion of Class B shares to
Class A shares, there are no conversion rights.
    
 
   
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, shares of a particular class of the Fund
may vote on matters affecting only that Class. The shares of the Fund and of the
Trust's other series will be voted in the aggregate on other matters, such as
the election of Trustees and ratification of the selection of the Trust's
independent accountants.
    
 
   
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. Shares of the Fund and the Trust's other series do
not have cumulative voting rights, which means that the holders of a majority of
the shares voting for the election of Trustees can elect all the Trustees. A
Trustee may be removed at any meeting of the shareholders of the Trust by a vote
of the shareholders owning at least two-thirds of the outstanding shares. Any
Trustee may call a special meeting of shareholders for any purpose. Furthermore,
Trustees shall promptly call a meeting of shareholders solely for the purpose of
removing one or more Trustees when requested in writing to do so by shareholders
holding 10% of the Trust's outstanding shares.
    
 
   
Pursuant to the Trust's Agreement and Declaration of Trust, the Trust may also
issue an unlimited number of shares of the Fund. Each share of the Fund
represents an interest in the Fund only, has a par value of $0.01 per share,
represents an equal proportionate interest in the Fund with other shares of the
Fund and is entitled to such dividends and distributions out of the income
earned and gain realized on the assets belonging to the Fund as may be declared
by the Board of Trustees. Each share of the Fund is equal in earnings, assets
and voting privileges except that each class normally has exclusive voting
rights with respect to its distribution plan and bears the expenses, if any,
related to the distribution of its shares. Shares of the Fund, when issued, are
fully paid and nonassessable.
    
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.

                                   APPENDIX A
                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from "Aaa" to "C." Investment grade ratings are the first
four categories:
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered as well-assured. Often the protection of
    interest and principal payments may be very moderate, and thereby not well
    safeguarded during both good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B -- Bonds which are rated B generally lack characteristics of the
    desirable investment. Assurance of interest and principal payments or of
    maintenance of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa are of poor standing. Such issues may
    be in default or there may be present elements of danger with respect to
    principal or interest.
 
        Ca -- Bonds which are rated Ca represent obligations which are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are rated C are the lowest rated class of bonds, and
    issues so rated can be regarded as having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.

<PAGE>
                           AIM STRATEGIC INCOME FUND
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various entities in categories ranging from "AAA"
to "D" according to quality. Investment grade ratings are the first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations rated "BB," "B," "CCC," "CC," and "C"
    are regarded as having significant speculative characteristics. "BB"
    indicates the least degree of speculation and "C" the highest. While such
    obligations will likely have some quality and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An obligation rated "BB" is less vulnerable to nonpayment than
    other speculative issues. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate capacity to meet its financial commitment
    on the obligation.
 
        B -- An obligation rated "B" is more vulnerable to nonpayment than
    obligations rated "BB," but the obligor currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its financial commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to have the capacity to meet its financial commitment on the
    obligation.
 
        CC -- An obligation rated "CC" is currently highly vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed or similar action has been taken, but payments on
    this obligation are being continued.
 
        D -- An obligation rated "D" is in payment default. The "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the applicable grace period has not expired, unless S&P believes
    that such payments will be made during such grace period. The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally will be evidenced by many of
the characteristics cited above but to a lesser degree. Earnings trends and
coverage ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

account; (d) accounts advised by INVESCO (NY), Inc. or one of the companies
formerly affiliated with Liechtenstein Global Trust AG, provided such accounts
were invested in Advisor Class shares on May 29, 1998; (e) any of the companies
affiliated with AMVESCAP PLC; and (f) AIM GLOBAL TRENDS FUND (certain Advisor
Class Funds only).
    
 
   
    Financial planners, trust companies, bank trust departments and registered
investment advisers referenced in clause (b) above, and sponsors of "wrap fee"
programs referenced in clause (c) above are collectively referred to as
"Financial Advisers." Financial Advisers and other fiduciaries may be required
to provide information satisfactory to AIM Distributors concerning their
eligibility to purchase Advisor Class shares.

<PAGE>
                              AIM INVESTOR'S GUIDE
   
Investors in wrap fee programs and advisory accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors. Investors may be charged a fee by their agents or brokers for
effecting transactions in Advisor Class shares.
    
 
   
    AIM Distributors may, from time to time, pay a bonus or other consideration
or incentive to dealers who sell a minimum dollar amount of the shares of the
AIM Funds during a specified period of time. In some instances, these incentives
may be offered only to certain dealers who have sold or may sell significant
amounts of shares. At the option of the dealer, such incentives may take the
form of payment for travel expenses, including lodging, incurred in connection
with trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
    
 
   
    TIMING OF PURCHASE ORDERS.  Orders for the purchase of Advisor Class shares
received prior to the close of regular trading on the New York Stock Exchange
("NYSE"), which is generally 4:00 p.m. Eastern Time (and which is hereinafter
referred to as "NYSE Close"), on any business day of an AIM Fund will be
confirmed at the price next determined. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of the AIM Fund.
Certain financial institutions (or their designees) may be authorized to accept
purchase orders on behalf of the AIM Funds. Orders received by authorized
institutions (or their designees) before NYSE Close will be deemed to have been
received by an AIM Fund on such day and will be effected that day, provided that
such orders are transmitted to the Transfer Agent prior to the time set for
receipt of such orders. It is the responsibility of the dealer/financial
institution to ensure that all orders are transmitted on a timely basis to the
Transfer Agent. Any loss resulting from the dealer/financial institution's
failure to submit an order within the prescribed time frame will be borne by
that dealer/financial institution. Please see "How to Purchase Shares -- Initial
and Subsequent Purchases by Wire" for information on obtaining a reference
number for wire orders, which will facilitate the handling of such orders and
ensure prompt credit to an investor's account. A "business day" of an AIM Fund
is any day on which the NYSE is open for business. It is expected that the NYSE
will be closed during the next twelve months on Saturdays and Sundays and on the
days on which New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day are observed by the NYSE.
    
 
   
    An investor who uses a check to purchase shares will be credited with the
full number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
    
 
   
    SPECIAL INFORMATION RELATING TO AIM DOLLAR FUND.  Because AIM DOLLAR FUND
uses the amortized cost method of valuing the securities it holds and rounds its
per share net asset value to the nearest whole cent, it is anticipated that the
net asset value of the shares of that fund will remain constant at $1.00 per
share. However, there is no assurance that AIM DOLLAR FUND can maintain a $1.00
net asset value per share. AIM DOLLAR FUND generally will not issue share
certificates but will record investor holdings in noncertificate form and
regularly advise the shareholder of his ownership position.
    
 
   
    SHARE CERTIFICATES.  Share certificates for all AIM Funds will be issued
upon written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem Shares --
Redemptions by Telephone" for restrictions applicable to shares issued in
certificate form.
    
 
    MINIMUM ACCOUNT BALANCE.  If (1) an account opened in a fund has been in
effect for at least one year and the shareholder has not made an additional
purchase in that account within the preceding six calendar months and (2) the
value of such account drops below $500 for three consecutive months as a result
of
 
                                      A-3
<PAGE>
                              AIM INVESTOR'S GUIDE
   
redemptions or exchanges, the fund has the right to redeem the account, after
giving the shareholder 60 days' prior written notice, unless the shareholder
makes additional investments within the notice period to bring the account value
up to $500. If a fund determines that a shareholder has provided incorrect
information in opening an account with a fund or in the course of conducting
subsequent transactions with the fund related to such account, the fund may, in
its discretion, redeem the account and distribute the proceeds of such
redemption to the shareholder.
    
 
    FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS
AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF
THE OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE
ORDER OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
- --------------------------------------------------------------------------------
 
[SPECIAL PLANS
 
   
    Except as noted below, each Advisor Class Fund provides the special plans
described below for the convenience of its Advisor Class shareholders. Once
established, there is no obligation to continue to invest through a plan, and a
shareholder may terminate a plan at any time.
    
 
   
    Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.
    
 
   
    AUTOMATIC DIVIDEND INVESTMENT PLAN.  Advisor Class shareholders may elect to
have all dividends and distributions declared by an Advisor Class Fund paid in
cash or invested at net asset value either in Advisor Class shares of the same
Advisor Class Fund or invested in shares of another Advisor Class Fund. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" for a
description of payment dates for these options. In order to qualify to have
dividends and distributions of one Advisor Class Fund invested in shares of
another Advisor Class Fund, the following conditions must be satisfied: (a) the
shareholder must have an account balance in the dividend paying fund of at least
$5,000; (b) the account must be held in the name of the shareholder (i.e., the
account may not be held in nominee name); and (c) the shareholder must have
requested and completed an authorization relating to the reinvestment of
dividends into another Advisor Class Fund. An authorization may be given on the
account application or on an authorization form available from AIM Distributors.
An Advisor Class Fund will waive the $5,000 minimum account value requirement if
the shareholder has an account in the fund selected to receive the dividends and
distributions with a value of at least $500.
    
 
   
    PORTFOLIO REBALANCING PROGRAM.  The Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of Advisor Class Funds. The Program automatically
rebalances holdings of Advisor Class Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, Advisor Class Funds ("Personal Portfolio") is to be
rebalanced on a quarterly, semiannual, or annual basis.
    
 
   
    Rebalancing under the Program will be effected through the exchange of
shares of one or more Advisor Class Funds in the shareholder's Personal
Portfolio for shares of the same class(es) of one or more other Advisor Class
Funds in the shareholder's Personal Portfolio. See "Exchange Privilege." If
shares of the Advisor Class Fund(s) in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of
Advisor Class Fund(s) that have appreciated most during the period being
exchanged for shares of Advisor Class Fund(s) that have appreciated least. SUCH
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends,
Distributions and Tax Matters -- Dividends and Distributions." Participation in
    
 
                                      A-4
<PAGE>
                              AIM INVESTOR'S GUIDE
the Program does not assure that a shareholder will profit from purchases under
the Program nor does it prevent or lessen losses in a declining market.
 
   
    The Program will automatically rebalance the shareholder's Personal
Portfolio on the 28th day of the last month of the period chosen (or the
immediately preceding business day if the 28th is not a business day), subject
to any limitations below. The Program will not execute an exchange if the
variance in a shareholder's Personal Portfolio for a particular Advisor Class
Fund would be 2% or less. In predesignating percentages, shareholders must use
whole percentages and totals must equal 100%. Shareholders participating in the
Program may not request issuance of physical certificates representing an
Advisor Class Fund's shares. The AIM Funds and AIM Distributors reserve the
right to modify, suspend, or terminate the Program at any time on 60 days' prior
written notice to shareholders. A request to participate in the Program must be
received in good order at least five business days prior to the next rebalancing
date. Once a shareholder establishes the Program for his or her Personal
Portfolio, a shareholder cannot cancel or change which rebalancing frequency,
which Advisor Class Funds or what allocation percentages are assigned to the
Program, unless canceled or changed in writing and received by the Transfer
Agent in good order at least five business days prior to the rebalancing date.
Certain dealers/financial institutions may charge a fee for establishing
accounts relating to the Program. Investors should contact their
dealers/financial institutions or AIM Distributors for more information.]
    
- --------------------------------------------------------------------------------
EXCHANGE PRIVILEGE
 
   
    TERMS AND CONDITIONS OF EXCHANGES.  Advisor Class shareholders of the
Advisor Class Funds may participate in an exchange privilege as described below.
AIM Distributors acts as distributor for the Advisor Class Funds which represent
a range of different investment objectives and policies.
    
 
   
    Advisor Class shares of any Advisor Class Fund may be exchanged only for
Advisor Class shares of any other Advisor Class Fund.
    
 
   
    Investors in wrap fee programs and advisory accounts interested in making an
exchange should contact their Financial Advisers to request the prospectus of an
Advisor Class Fund being considered. Other investors should contact AIM
Distributors for the appropriate prospectus.
    
 
   
    An exchange is permitted only in the following circumstances: (a) the dollar
amount of the exchange must be at least equal to the minimum investment
applicable to the shares of the Advisor Class Fund acquired through such
exchange; (b) the shares of the Advisor Class Fund acquired through exchange
must be qualified for sale in the state in which the shareholder resides; (c)
the exchange must be made between accounts having identical registrations and
addresses; (d) the full amount of the purchase price for the shares being
exchanged must have already been received by the fund; (e) the account from
which shares have been exchanged must be coded as having a certified taxpayer
identification number on file or, in the alternative, an appropriate IRS Form
W-8 (certificate of foreign status) or Form W-9 (certifying exempt status) must
have been received by the fund; (f) newly acquired shares (through either an
initial or subsequent investment) are held in an account for at least ten
business days, and all other shares are held in an account for at least one day,
prior to the exchange; and (g) certificates representing shares must be returned
before shares can be exchanged. There is no fee for exchanges among the Advisor
Class Funds.
    
 
   
    THE CURRENT PROSPECTUS OF EACH OF THE ADVISOR CLASS FUNDS AND CURRENT
INFORMATION CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE
THROUGH AIM DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE
AGREEMENT WITH AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD
REVIEW THE PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH
EXCHANGE. EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE
INCOME TAX PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
    
 
    THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
   
    Shares of any Advisor Class Fund to be exchanged are redeemed at their net
asset value as determined at NYSE Close on the day that an exchange request in
proper form (described below) is received. Exchange requests received after NYSE
Close will result in the redemption of shares at their net asset value at NYSE
Close on the next business day. Normally, Advisor Class shares of an Advisor
Class Fund to be acquired by exchange are purchased at their net asset value
determined on the date that such request is received, but
    
 
                                      A-5
<PAGE>
                              AIM INVESTOR'S GUIDE
   
under unusual market conditions such purchases may be delayed for up to five
business days if it is determined that an Advisor Class Fund would be materially
disadvantaged by an immediate transfer of the proceeds of the exchange. If a
shareholder is exchanging into an Advisor Class Fund that declares daily
dividends ("Dividends, Distributions and Tax Matters -- Dividends and
Distributions," below), and the release of the exchange proceeds is delayed for
the foregoing five-day period, such shareholder will not begin to accrue
dividends until the sixth business day after the exchange. Advisor Class shares
purchased by check may not be exchanged until it is determined that the check
has cleared, which may take up to ten business days from the date that the check
is received. See "Terms and Conditions of Purchase of the AIM Funds -- Timing of
Purchase Orders."
    
 
   
    In the event of unusual market conditions, AIM Distributors reserves the
right to reject any exchange request, if, in the judgment of AIM Distributors,
the number of requests or the total value of the shares that are the subject of
the exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
    
 
   
    EXCHANGES BY MAIL.  Investors exchanging their Advisor Class shares by mail
should send a written request to AFS. The request should contain the account
registration and account number, the dollar amount or number of Advisor Class
shares to be exchanged, and the names of the Advisor Class Funds from which and
into which the exchange is to be made. The request should comply with all of the
requirements for redemption by mail. See "How to Redeem Shares."
    
 
   
    EXCHANGES BY TELEPHONE.  Shareholders or their agents may request an
exchange by telephone. A shareholder may give exchange information to his
Financial Adviser. If a shareholder does not wish to allow telephone exchanges
by any person in his account, he should decline that option on the account
application. AIM Distributors has made arrangements with certain dealers and
investment advisory firms to accept telephone instructions to exchange shares
between any of the Advisor Class Funds. AIM Distributors reserves the right to
impose conditions on dealers or investment advisors who make telephone exchanges
of shares of the Advisor Class Funds, including the condition that any such
dealer or investment advisor enter into an agreement (which contains additional
conditions with respect to exchanges of shares) with AIM Distributors. To
exchange shares by telephone, a Financial Adviser, shareholder or dealer who has
satisfied the foregoing conditions must call AFS at (800) 959-4246. If a
Financial Adviser, shareholder or dealer is unable to reach AFS by telephone, he
may also request exchanges by telegraph or use overnight courier services to
expedite exchanges by mail, which will be effective on the business day received
by the Transfer Agent as long as such request is received prior to NYSE Close.
The Transfer Agent and AIM Distributors will not be liable for any loss, expense
or cost arising out of any telephone exchange request that they reasonably
believe to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's Social Security Number
and current address, and mailings of confirmations promptly after the
transaction.
    
- --------------------------------------------------------------------------------
HOW TO REDEEM SHARES
 
   
    Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer/ financial institution who has entered into an agreement with
AIM Distributors. In addition to the obligation of the fund(s) named on the
cover page to redeem shares, AIM Distributors also repurchases shares. No
redemption fee is imposed when Advisor Class shares are redeemed or repurchased;
however, dealers/ financial institutions may charge service fees for handling
repurchase transactions.
    
 
    REDEMPTIONS BY MAIL.  Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
   
    Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
    
 
                                      A-6
<PAGE>
                              AIM INVESTOR'S GUIDE
   
corporations, partnership, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
    
 
   
    REDEMPTIONS BY TELEPHONE.  Shareholders may request a redemption by
telephone. If a shareholder does not wish to allow telephone redemptions by any
person in his account, he should decline that option on the account application.
The telephone redemption feature can be used only if: (a) the redemption
proceeds are to be mailed to the address of record or transferred electronically
or wired to the pre-authorized bank account; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) the shares to
be redeemed are not in certificate form; (d) the person requesting the
redemption can provide proper identification information, and (e) the proceeds
of the redemption do not exceed $50,000. AIM Distributors has made arrangements
with certain dealers and investment advisors to accept telephone instructions
for the redemption of shares. AIM Distributors reserves the right to impose
conditions on these dealers and investment advisors, including the condition
that they enter into agreements (which contain additional conditions with
respect to the redemption of shares) with AIM Distributors. The Transfer Agent
and AIM Distributors will not be liable for any loss, expense or cost arising
out of any telephone redemption request effected in accordance with the
authorization set forth in the appropriate form if they reasonably believe such
request to be genuine, but may in certain cases be liable for losses due to
unauthorized or fraudulent transactions if they do not follow reasonable
procedures for verification of telephone transactions. Such reasonable
procedures may include recordings of telephone transactions (maintained for six
months), requests for confirmation of the shareholder's taxpayer identification
number and current address, and mailings of confirmations promptly after the
transaction.
    
 
   
    TIMING AND PRICING OF REDEMPTION ORDERS.  Advisor Class shares of the
Advisor Class Funds are redeemed at their net asset value next computed after a
request for redemption in proper form (including signature guarantees and other
required documentation for written redemptions) is received by the Transfer
Agent or certain financial institutions (or their designees) who are authorized
to accept redemption orders on behalf of the AIM Funds, provided that such
orders are transmitted to the Transfer Agent prior to the time set for receipt
of such orders. Orders for the redemption of Advisor Class shares received on
any business day of an AIM Fund will be confirmed at the price determined as of
the close of that day. Orders received after NYSE Close will be confirmed at the
price determined on the next business day of an AIM Fund. It is the
responsibility of the dealer/financial institution to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer/financial
institution's failure to submit a request for redemption within the prescribed
time frame will be borne by that dealer/financial institution. Telephone
redemption requests must be made by NYSE Close on any business day of an AIM
Fund and will be confirmed at the price determined as of the close of that day.
No AIM Fund will accept requests which specify a particular date for redemption
or which specify any special conditions.
    
 
    Payment of the proceeds of redeemed shares is normally made within seven
days following the redemption date. However, in the event of a redemption of
shares purchased by check, the investor may be required to wait up to ten
business days before the redemption proceeds are sent. See "Terms and Conditions
of Purchase of the AIM Funds -- Timing of Purchase Orders." A charge for special
handling (such as wiring of funds or expedited delivery services) may be made by
the Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.
 
    SIGNATURE GUARANTEES.  A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner, (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions, and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the
 
                                      A-7
<PAGE>
                              AIM INVESTOR'S GUIDE
proceeds are to be sent to the address of record. These requirements may be
waived or modified upon notice to shareholders.
 
    Acceptable guarantors include banks, broker-dealers, credit unions, national
securities exchanges, savings associations and any other organization, provided
that such institution or organization qualifies as an "eligible guarantor
institution" as that term in defined in rules adopted by the Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent will also accept signatures with either: (1) a signature
guaranteed with a medallion stamp of the STAMP Program, or (2) a signature
guaranteed with a medallion stamp of the NYSE Medallion Signature Program,
provided that in either event, the amount of the transaction involved does not
exceed the surety coverage amount indicated on the medallion. For information
regarding whether a particular institution or organization qualifies as an
"eligible guarantor institution," an investor should contact the Client Services
Department of AFS.
- --------------------------------------------------------------------------------
   
DETERMINATION OF NET ASSET VALUE
    
 
   
    The net asset value per share (or share price) of each Advisor Class Fund is
determined as of 4:00 p.m. Eastern Time on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an Advisor Class
Fund's share will be determined as of the close of the NYSE on such day. For
purposes of defining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE. The
net asset value per share is calculated by subtracting a class' liabilities from
its assets and dividing the result by the total number of class shares
outstanding. The determination of net asset value per share is made in
accordance with generally accepted accounting principles. Among other items,
liabilities include accrued expenses and dividends payable, and total assets
include portfolio securities valued at their market value, as well as income
accrued but not yet received. Securities for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the supervision of the fund's officers and in accordance with methods
which are specifically authorized by its governing Board of Directors or
Trustees. Short-term obligations with maturities of 60 days or less, and the
securities held by the AIM DOLLAR FUND, are valued at amortized cost as
reflecting fair value.
    
 
   
    Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund. Securities listed primarily on foreign exchanges may trade
on days when the NYSE is closed (such as a Saturday). As a result, the net asset
value of a fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that fund.

    In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods. Each Advisor Class Fund
may make additional distributions, if necessary, to avoid a non-deductible 4%
federal excise tax on certain undistributed income and capital gain (the "Excise
Tax").
    
 
   
    All dividends and distributions of an AIM Fund are automatically reinvested
on the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to Advisor Class shares of an Advisor
Class Fund are reinvested in additional Advisor Class shares of that fund,
absent an election by a shareholder to receive cash or to have such dividends
and distributions reinvested in Advisor Class shares of another Advisor Class
Fund, to the extent permitted. For funds that do not declare a dividend daily,
such dividends and distributions will be reinvested at the net asset value per
share determined on the ex-dividend date. For funds that declare a dividend
daily, such dividends and distributions will be reinvested at the net asset
value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or only the
dividend portion thereof, in cash, or to invest such dividends and distributions
in Advisor Class shares of another Advisor Class Fund. Investors who have not
previously selected such a reinvestment option on the account application form
may contact the Transfer Agent at any time to obtain a form to authorize such
reinvestments in another Advisor Class Fund.
    
 
   
    Dividends on Advisor Class shares of an Advisor Class Fund are expected to
be higher than dividends on shares of other classes of that fund because of the
service and distribution fees paid by those other classes of shares. Dividends
on all shares may also be affected by other class-specific expenses.
    
 
   
    Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such payment. Any dividend and distribution election remains
in effect until the Transfer Agent receives a revised written election by the
shareholder.
    
 
   
    Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.

                              AIM INVESTOR'S GUIDE
 
TAX MATTERS
 
    Each AIM Fund has qualified and intends to continue to qualify for treatment
as a regulated investment company under Subchapter M of the Code. As long as a
fund qualifies for this tax treatment, it is not subject to federal income tax
on net investment income, net capital gains and net gains from foreign currency
transactions, if any, that are distributed to its shareholders. Each fund, for
all federal tax purposes (including determining taxable income, distribution
requirements and other requirements of Subchapter M), is treated as a separate
corporation. Therefore, no fund may offset its gains against another fund's
losses, and each fund must individually comply with all of the provisions of the
Code that are applicable to its operations.
 
   
    TAX TREATMENT OF DIVIDENDS AND DISTRIBUTIONS -- GENERAL.  Because each AIM
Fund intends to distribute to its shareholders substantially all of its net
investment income, net realized capital gains and net gains from foreign
currency transactions, if any, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid imposition of the Excise Tax.
Nevertheless, shareholders normally are subject to federal income tax, and any
applicable state and local income taxes, on the dividends and distributions
received by them from a fund whether in the form of cash or additional fund
shares. With respect to tax-exempt shareholders, dividends and distributions
from the AIM Funds are not subject to federal income taxation to the extent
permitted under the applicable tax exemption.
    
 
    Dividends from an AIM Fund's net investment income, net short-term capital
gain and net gains from certain foreign currency transactions are taxable to its
shareholders as ordinary income to the extent of its earnings and profits.
Distributions of net capital gain (i.e., the excess of net long-term capital
gain over net short-term capital loss) are taxable as long-term capital gains,
regardless of the length of time the shareholder held his shares. Under the
Taxpayer Relief Act of 1997, different maximum tax rates apply to a non-
corporate taxpayer's net capital gain depending on the taxpayer's holding period
and marginal rate of federal income tax -- generally, 28% for gain recognized on
capital assets held for more than one year but not more than 18 months and 20%
(10% for taxpayers in the 15% marginal tax bracket) for gain recognized on
capital assets held for more than 18 months. An AIM Fund may divide each net
capital gain distribution into a 28% rate gain distribution and a 20% rate gain
distribution (in accordance with its holding periods for the securities it sold
that generated the distributed gain), in which event its shareholders must treat
those portions accordingly; thus, the relevant holding period is determined by
how long the fund has held the securities on which the gain was realized, not by
how long a shareholder has held fund shares.
 
   
    Dividends paid by a fund (but not other distributions) may qualify for the
federal 70% dividends received deduction for corporate shareholders to the
extent of the qualifying dividends received by the fund on domestic common or
preferred stock. It is not likely that dividends received from AIM Developing
Markets Fund, AIM Dollar Fund, AIM Emerging Markets Fund, AIM Europe Growth
Fund, AIM Global Government Income Fund, AIM Global High Income Fund, AIM Global
Trends Fund, AIM International Growth Fund, AIM Japan Growth Fund, AIM Latin
American Growth Fund, AIM New Pacific Growth Fund and AIM Strategic Income Fund
will qualify for this dividends received deduction.
    
 
    Shortly after the end of each year, shareholders will receive information
regarding the amount and federal income tax treatment of all dividends and
distributions paid during the year. The information regarding capital gain
distributions will designate the portions thereof subject to the different
maximum rates of tax applicable to non-corporate taxpayers' net capital gain
indicated above. Certain dividends and distributions declared in October,
November or December of a calendar year are taxable to shareholders as though
received on December 31 of that year if paid to them during January of the
following calendar year.
 
    For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
    TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31%
ON TAXABLE DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A
FUND MUST FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
UNDER PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE
NOT SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
    Under the Code, nonresident alien individuals, foreign partnerships and
foreign corporations may be subject to federal income tax withholding at a 30%
rate on ordinary income dividends. Under applicable treaty law, residents of
treaty countries may qualify for a reduced rate of withholding or a withholding
exemption.

    DIVIDENDS AND DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE

DISCUSSED HEREIN. ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE

    AIM AMERICA VALUE FUND, AIM DOLLAR FUND, AIM GLOBAL GOVERNMENT INCOME FUND,
AIM GLOBAL GROWTH & INCOME FUND, AIM GLOBAL HIGH INCOME FUND, AIM MID CAP GROWTH
FUND, AIM SMALL CAP EQUITY FUND AND AIM STRATEGIC INCOME FUND -- SPECIAL TAX
INFORMATION. Certain states exempt from income taxes dividends paid by mutual
funds attributable to interest on U.S. Treasury and certain other U.S.
government obligations. Investors should consult with their own tax advisors
concerning the availability of such exemption.
    
 
   
    AIM DEVELOPING MARKETS FUND, AIM EMERGING MARKETS FUND, AIM EUROPE GROWTH

GLOBAL INFRASTRUCTURE FUND, AIM GLOBAL RESOURCES FUND, AIM GLOBAL
TELECOMMUNICATIONS FUND, AIM INTERNATIONAL GROWTH FUND, AIM JAPAN GROWTH FUND,
AIM LATIN AMERICAN GROWTH FUND, AIM NEW PACIFIC GROWTH FUND AND AIM WORLDWIDE
GROWTH FUND -- SPECIAL TAX INFORMATION.  For taxable years in which it is
eligible to do so, each of these funds may elect to pass through to its
shareholders credits for foreign taxes paid. If a fund makes such an election, a
shareholder who receives a distribution (1) will be required to include in gross
income his proportionate share of foreign taxes allocable to the distribution
and (2) may claim a credit or deduction for such share for his taxable year in
which the distribution is received, subject to the general limitations imposed
on the allowance of foreign tax credits and deductions. Shareholders should also
note that certain gains or losses attributable to fluctuations in exchange rates
or foreign currency forward contracts may increase or decrease the amount of
income of the fund available for distribution to shareholders and should note
that if, for any fund, such losses exceed other income during a taxable year,
the fund would not be able to pay ordinary income dividends for that year.

    CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, 225
Franklin Street, Boston, Massachusetts 02110, serves as custodian for the
portfolio securities and cash of the Advisor Class Funds. Chase Bank of Texas,
N.A., P.O. Box 2558, Houston, Texas 77252-8084, serves as Sub-Custodian for
retail purchases of the AIM Funds.
 
    A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas 77210-4739, a
wholly-owned subsidiary of AIM, serves as each Advisor Class Fund's transfer
agent and dividend payment agent.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries concerning their accounts
should be directed to an A I M Fund Services, Inc. Client Services
Representative by calling (800) 959-4246. The Transfer Agent may impose certain
copying charges for requests for copies of shareholder account statements and
other historical account information older than the current year and the
immediately preceding year.
 
    YEAR 2000 COMPLIANCE PROJECT.  In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties (the "Software"). Many
software systems in use today are unable to distinguish between the year 2000
from the year 1900. This defect if not cured will likely adversely affect the
services that AIM Management, its subsidiaries and other service providers to
the AIM Funds provide the AIM Funds and their shareholders.
 
    To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and Phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.

High  Income Fund, AIM Strategic Income Fund, AIM Global Growth and Income Fund,
AIM Emerging Markets Fund, AIM Developing  Markets Fund, and AIM Latin  American
Growth  Fund. Each of these  funds has three separate  classes: Class A, Class B
and Advisor  Class  shares.  All  historical  financial  and  other  information
contained  in  this Statement  of Additional  Information  for periods  prior to
September 4, 1998, is that of the series of G.T. Investment Funds, Inc. (renamed
AIM Investment Funds, Inc.)
    
 
   
This Statement of  Additional Information relates  solely to the  Class A and  B
shares of the Fund.
    
 
   
The term "majority of the outstanding shares" of the Trust, of a particular Fund
or  of a particular class of a Fund  means, respectively, the vote of the lesser
of (a) 67% or more of the shares  of the Trust, such Fund or such class  present
at a meeting of the Trust's shareholders, if the holders of more than 50% of the
outstanding  shares  of  the Trust,  such  Fund  or such  class  are  present or
represented by proxy,  or (b) more  than 50%  of the outstanding  shares of  the
Trust, such Fund or such class.

                         AIM LATIN AMERICAN GROWTH FUND
 
   
Class  A, Class B  and Advisor Class shares  of each Fund  have equal rights and
privileges. Each  share  of a  particular  class is  entitled  to one  vote,  to
participate equally in dividends and distributions declared by the Trust's Board
of  Trustees with respect to the class of such Fund and, upon liquidation of the
Fund, to participate proportionately in the net assets of the Fund allocable  to
such  class remaining after satisfaction of  outstanding liabilities of the Fund
allocable to such class.  Fund shares are fully  paid, non-assessable and  fully
transferable  when issued and have no preemptive rights and have such conversion
and exchange  rights  as set  forth  in the  Prospectus  and this  Statement  of
Additional  Information. Fractional shares have proportionately the same rights,
including voting rights, as are provided for a full share.
    
 
   
Shareholders of the Funds  do not have cumulative  voting rights, and  therefore
the  holders of  more than  50% of  the outstanding  shares of  all Funds voting
together for election of directors may elect all of the members of the Board  of
Trustees  of the Trust.  In such event,  the remaining holders  cannot elect any
trustees of the Trust.

                           INVESTMENT OBJECTIVES AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
INVESTMENT OBJECTIVES
   
    DEVELOPING MARKETS FUND.   The  primary investment  objective of  Developing
Markets  Fund  is  long-term  capital  appreciation.  Its  secondary  investment
objective is income, to the extent consistent with seeking capital appreciation.
The Fund normally  invests substantially  all of its  assets in  issuers in  the
developing (or "emerging") markets of Asia, Europe, Latin America and elsewhere.
The  Fund  does not  consider the  following countries  to be  emerging markets:
Australia, Austria, Belgium, Canada, Denmark, England, Finland, France, Germany,
Ireland, Italy,  Japan, the  Netherlands, New  Zealand, Norway,  Spain,  Sweden,
Switzerland and the United States.
    
 
   
    EMERGING  MARKETS FUND. The investment objective of Emerging Markets Fund is
long-term growth of capital. The Fund  seeks this objective by investing,  under
normal  circumstances, at least 65% of its  total assets in equity securities of
companies in  emerging  markets.  The  Fund  does  not  consider  the  following
countries  to be emerging markets: Australia, Austria, Belgium, Canada, Denmark,
England, Finland, France, Germany, Ireland,  Italy, Japan, the Netherlands,  New
Zealand, Norway, Spain, Sweden, Switzerland and United States. The Fund normally
may  invest up to 35% of  its assets in a combination  of (i) debt securities of
government or  corporate  issuers in  emerging  markets; (ii)  equity  and  debt
securities of issuers in developed countries, including the United States; (iii)
securities  of issuers in emerging markets not  included in the list of emerging
markets set forth in the Fund's current Prospectus, if investing therein becomes
feasible and desirable subsequent to the date of the Fund's current  Prospectus;
and (iv) cash and money market instruments.
    
 
   
In  determining  what  countries  constitute emerging  markets  with  respect to
Developing Market Fund and Emerging Markets Fund, the Sub-adviser will consider,
among other things, data, analysis, and classification of countries published or
disseminated by  the  International  Bank  for  Reconstruction  and  Development
(commonly  known as  the World Bank)  and the  International Finance Corporation
("IFC").
    
 
   
    LATIN AMERICAN  FUND. The  investment objective  of Latin  American Fund  is
capital  appreciation. The Fund will  normally invest at least  65% of its total
assets in securities of a broad  range of Latin American issuers. Under  current
market  conditions,  the Fund  expects to  invest primarily  in equity  and debt
securities issued  by companies  and governments  in Mexico,  Chile, Brazil  and
Argentina.  Though the Fund can normally invest up to 35% of its total assets in
U.S. securities, the Fund  reserves the right to  be primarily invested in  U.S.
securities  for  temporary  defensive  purposes  or  pending  investment  of the
proceeds of the offering made hereby.
    
 
SELECTION OF EQUITY INVESTMENTS
   
In  determining  the  appropriate  distribution  of  investments  among  various
countries  and  geographic regions  for  the Funds,  the  Sub-adviser ordinarily
considers the following  factors: prospects for  relative economic growth  among
the  different  countries  in  which  a  Fund  may  invest;  expected  levels of
inflation; government policies influencing business conditions; the outlook  for
currency relationships; and the range of the individual investment opportunities
available to international investors.
    
 
                   Statement of Additional Information Page 4
<PAGE>
                          AIM DEVELOPING MARKETS FUND
                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
   
In  analyzing companies for investment by  each Fund, the Sub-adviser ordinarily
looks for  one  or  more  of the  following  characteristics:  an  above-average
earnings  growth per  share; high  return on  invested capital;  healthy balance
sheet; sound financial and accounting  policies and overall financial  strength;
strong  competitive advantages;  effective research and  product development and
marketing; efficient service; pricing  flexibility; strength of management;  and
general  operating characteristics  which will  enable the  companies to compete
successfully  in   their   respective  marketplaces.   In   certain   countries,
governmental  restrictions and  other limitations  on investment  may affect the
maximum percentage  of equity  ownership in  any one  company by  the Funds.  In
addition,  in some instances only special classes of securities may be purchased
by foreigners and the market prices, liquidity and rights with respect to  those
securities may vary from shares owned by nationals.
    
 
   
Although  the Funds value their assets daily in terms of U.S. dollars, the Funds
do not intend to convert their holdings of foreign currencies into U.S.  dollars
on  a daily basis. The Funds will do  so from time to time, and investors should
be aware of the costs of currency conversion. Although foreign exchange  dealers
do  not charge  a fee  for conversion,  they do  realize a  profit based  on the
difference ("spread") between the  prices at which they  are buying and  selling
various  currencies. Thus, a dealer may offer  to sell a foreign currency to the
Funds at one rate, while offering a lesser rate of exchange should a Fund desire
to sell that currency to the dealer.
    
 
   
There may be times when, in  the opinion of the Sub-adviser, prevailing  market,
economic  or political conditions warrant reducing the proportion of each Fund's
assets invested in equity securities and increasing the proportion held in  cash
or  short-term obligations  denominated in U.S.  dollars or  other currencies. A
portion of  each  Fund's  assets may  be  held  in U.S.  dollars  or  short-term
interest-bearing  dollar-denominated securities to  provide for ongoing expenses
and redemptions.
    
 
   
The Funds may be prohibited under the Investment Company Act of 1940, as amended
("1940 Act"), from purchasing the securities of any foreign company that, in its
most recent  fiscal year,  derived more  than  15% of  its gross  revenues  from
securities-related  activities ("securities-related companies").  In a number of
countries, including those in Latin America, commercial banks act as  securities
broker/dealers,  investment  advisers and  underwriters  or otherwise  engage in
securities-related activities,  which  may  limit the  Fund's  ability  to  hold
securities  issued by such  banks. The Fund  has obtained an  exemption from the
Securities and Exchange Commission ("SEC") to permit it to invest in certain  of
these securities subject to certain restrictions.
    
 
   
For  investment  purposes, an  issuer is  typically considered  as located  in a
particular country  if it  (a) is  incorporated under  the laws  of or  has  its
principal  office in that country, or (b) it normally derives 50% or more of its
total revenue from  business in that  country. However, these  are not  absolute
requirements,  and certain  companies incorporated  in a  particular country and
considered by the Sub-adviser to be located in that country may have substantial
off-shore operations or subsidiaries and/or  export sales exceeding in size  the
assets or sales in that country.
    
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
   
The  Funds  may  invest in  the  securities of  investment  companies (including
investment vehicles or companies  advised by the  Sub-adviser or its  affiliates
("Affiliated  Funds"))  within the  limits of  the  1940 Act.  These limitations
currently provide  that,  in  general,  each  Fund  may  purchase  shares  of  a
closed-end investment company unless (a) such a purchase would cause the Fund to
own  in the aggregate more than 3  percent of the total outstanding voting stock
of the investment company or  (b) such a purchase would  cause the Fund to  have
more  than 5 percent of  its total assets invested  in the investment company or
more than 10 percent of  its total assets invested in  an aggregate of all  such
investment  companies. Investment in such  investment companies may also involve
the payment of substantial premiums above the value of such companies' portfolio
securities. The  Funds do  not intend  to invest  in such  investment  companies
unless,  in  the judgment  of the  Sub-adviser, the  potential benefits  of such
investments justify the payment of any  applicable premiums. The return on  such
securities  will be  reduced by operating  expenses of  such companies including
payments to the investment managers of those investment companies. With  respect
to  investments in Affiliated Funds, the  Sub-adviser waives its advisory fee to
the extent that such fees are based on assets of the Fund invested in Affiliated
Funds.
    
 
   
Certain countries  in which  the Funds  invest  presently may  be made  only  by
acquiring  shares of other investment companies with local governmental approval
to invest  in  those countries.  At  such time  as  direct investment  in  those
countries is allowed, the Funds anticipate investing directly in those markets.

                         AIM LATIN AMERICAN GROWTH FUND
 
DEPOSITORY RECEIPTS
   
Each  Fund may hold equity securities of foreign issuers in the form of American
Depository  Receipts  ("ADRs"),  American  Depository  Shares  ("ADSs"),  Global
Depository Receipts ("GDRs") and European Depository Receipts ("EDRs"), or other
securities convertible into securities of eligible issuers. These securities may
not  necessarily be denominated in the same currency as the securities for which
they may be exchanged. ADRs and ADSs typically are issued by an American bank or
trust company  and  evidence ownership  of  underlying securities  issued  by  a
foreign  corporation.  EDRs,  which  are sometimes  referred  to  as Continental
Depository Receipts ("CDRs"), are  issued in Europe  typically by foreign  banks
and  trust  companies  and  evidence ownership  of  either  foreign  or domestic
securities. GDRs  are  similar to  EDRs  and are  designed  for use  in  several
international financial markets. Generally, ADRs and ADSs in registered form are
designed for use in United States securities markets and EDRs in bearer form are
designed  for use  in European securities  markets. For purposes  of each Fund's
investment policies, a Fund's investments in  ADRs, ADSs, GDRs and EDRs will  be
deemed  to be  investments in the  equity securities  representing securities of
foreign issuers into which they may be converted.
    
 
ADR facilities may be established as either "unsponsored" or "sponsored."  While
ADRs  issued under these two  types of facilities are  in some respects similar,
there are distinctions between  them relating to the  rights and obligations  of
ADR holders and the practices of market participants. A depository may establish
an  unsponsored  facility  without  participation by  (or  even  necessarily the
acquiescence of) the issuer of the deposited securities, although typically  the
depository  requests a  letter of  non-objection from  such issuer  prior to the
establishment of the facility.  Holders of unsponsored  ADRs generally bear  all
the  costs  of such  facilities. The  depository usually  charges fees  upon the
deposit and withdrawal of the deposited securities, the conversion of  dividends
into   U.S.  dollars,  the  disposition   of  non-cash  distributions,  and  the
performance of  other  services.  The  depository  of  an  unsponsored  facility
frequently  is  under  no obligation  to  distribute  shareholder communications
received from the issuer of the  deposited securities or to pass-through  voting
rights  to ADR  holders in  respect of  the deposited  securities. Sponsored ADR
facilities are created in generally  the same manner as unsponsored  facilities,
except  that  the  issuer of  the  deposited  securities enters  into  a deposit
agreement with the  depository. The deposit  agreement sets out  the rights  and
responsibilities  of  the  issuer,  the depository  and  the  ADR  holders. With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository), although ADR holders continue to bear certain other costs (such  as
deposit  and withdrawal fees).  Under the terms  of most sponsored arrangements,
depositories agree  to distribute  notices of  shareholder meetings  and  voting
instructions, and to provide shareholder communications and other information to
the  ADR holders at the  request of the issuer  of the deposited securities. The
Fund may invest in both sponsored and unsponsored ADRs.
 
WARRANTS OR RIGHTS
   
Warrants or  rights  may be  acquired  by each  Fund  in connection  with  other
securities  or separately  and provide a  Fund with  the right to  purchase at a
later date other securities of  the issuer. Warrants are securities  permitting,
but   not  obligating,  their  holder  to  subscribe  for  other  securities  or
commodities. Warrants do not  carry with them the  right to dividends or  voting
rights  with  respect  to  the  securities that  they  entitle  their  holder to
purchase, and they do not represent any rights in the assets of the issuer. As a
result, warrants may be considered more speculative than certain other types  of
investments.  In addition,  the value of  a warrant does  not necessarily change
with the value of the underlying securities  and a warrant ceases to have  value
if it is not exercised prior to its expiration date.
    
 
LENDING OF PORTFOLIO SECURITIES
   
For the purpose of realizing additional income, the Funds may make secured loans
of  portfolio  securities  amounting  to  not more  than  30%  (in  the  case of
Developing Markets Fund and Emerging Markets Fund) or 25% (in the case of  Latin
American  Fund) of its total assets. Securities loans are made to broker/dealers
or institutional  investors  pursuant to  agreements  requiring that  the  loans
continuously  be secured by collateral at least  equal at all times to the value
of the securities lent plus any accrued interest, "marked to market" on a  daily
basis.  The  Funds  may  pay reasonable  administrative  and  custodial  fees in
connection  with  loans  of  its  securities.  While  the  securities  loan   is
outstanding  with  respect to  a Fund,  the  Fund will  continue to  receive the
equivalent of the interest or dividends paid by the issuer on the securities, as
well as interest on the investment of the collateral or a fee from the borrower.
The Fund will have a  right to call each loan  and obtain the securities  within
the  stated settlement period. The  Fund will not have  the right to vote equity
securities while they are lent, but it may call in a loan in anticipation of any
important vote. Loans will be made only to firms deemed by the Sub-adviser to be
of good  standing  and  will  not  be  made  unless,  in  the  judgment  of  the
Sub-adviser,  the consideration to  be earned from such  loans would justify the
risk.

                         AIM LATIN AMERICAN GROWTH FUND
 
COMMERCIAL BANK OBLIGATIONS
   
For the  purposes  of each  Fund's  investment  policies with  respect  to  bank
obligations,  obligations of foreign branches of U.S. banks and of foreign banks
are obligations of the issuing bank and may be general obligations of the parent
bank. Such  obligations, however,  may be  limited by  the terms  of a  specific
obligation  and  by  government  regulation.  As  with  investment  in  non-U.S.
securities in general,  investments in  the obligations of  foreign branches  of
U.S.  banks and of foreign banks may subject a Fund to investment risks that are
different in some respects from those of investments in obligations of  domestic
issuers. Although a Fund typically will acquire obligations issued and supported
by  the credit  of U.S.  or foreign  banks having  total assets  at the  time of
purchase in excess of $1  billion, this $1 billion  figure is not an  investment
policy  or restriction of any Fund. For the purposes of calculation with respect
to the $1 billion  figure, the assets of  a bank will be  deemed to include  the
assets of its U.S. and non-U.S. branches.
    
 
REPURCHASE AGREEMENTS
   
A  repurchase agreement is  a transaction in  which a Fund  purchases a security
from a bank or recognized securities dealer and simultaneously commits to resell
that security to the bank  or dealer at an agreed  upon price, date, and  market
rate  of interest  unrelated to  the coupon  rate or  maturity of  the purchased
security. Although repurchase agreements carry certain risks not associated with
direct investments in securities, including possible decline in the market value
of the underlying securities and delays and  costs to a Fund if the other  party
to  the repurchase  agreement becomes bankrupt,  the Funds intend  to enter into
repurchase agreements only with banks and dealers believed by the Sub-adviser to
present minimum credit risks  in accordance with  guidelines established by  the
Trust's  Board  of  Trustees.  The  Sub-adviser  will  review  and  monitor  the
creditworthiness of such institutions under the Board's general supervision.
    
 
   
The Funds will invest only in repurchase agreements collateralized at all  times
in  an amount at least  equal to the repurchase  price plus accrued interest. To
the extent that the proceeds from any sale of such collateral upon a default  in
the  obligation to repurchase were less than  the repurchase price, a Fund would
suffer a loss.  If the financial  institution which is  party to the  repurchase
agreement petitions for bankruptcy or otherwise becomes subject to bankruptcy or
other  liquidation proceedings, there may be restrictions on a Fund's ability to
sell the collateral and the Fund could  suffer a loss. However, with respect  to
financial  institutions whose bankruptcy or  liquidation proceedings are subject
to the U.S. Bankruptcy Code, each  Fund intends to comply with provisions  under
the  U.S.  Bankruptcy  Code  that  would  allow  it  immediately  to  resell the
collateral. There is no limitation on the amount of a Fund's assets that may  be
subject  to repurchase agreements  at any given  time. The Funds  will not enter
into a repurchase agreement  with a maturity  of more than seven  days if, as  a
result, more than 15% (for Emerging Markets Fund and Developing Markets Fund) or
10%  (for Latin American Fund) of the value  of its net assets would be invested
in such repurchase agreements and other illiquid investments.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
    
   
No Fund's borrowings will exceed 33 1/3% of the Fund's total assets, i.e.,  each
Fund's  total assets  at all  times will equal  at least  300% of  the amount of
outstanding borrowings.  If  market  fluctuations  in  the  value  of  a  Fund's
portfolio  holdings or other factors cause the  ratio of the Fund's total assets
to outstanding  borrowings to  fall  below 300%,  within three  days  (excluding
Sundays  and holidays) of such event the  Fund may be required to sell portfolio
securities to restore the  300% asset coverage, even  though from an  investment
standpoint  such sales might be disadvantageous. Each Fund also may borrow up to
5% of its total assets  for temporary or emergency  purposes other than to  meet
redemptions.  Any borrowing by a Fund may cause greater fluctuation in the value
of its shares than would be the case if the Fund did not borrow.
    
 
   
The Funds' fundamental investment  limitations permit them  to borrow money  for
leveraging  purposes. Developing Market Fund,  however, currently is prohibited,
pursuant to a non-fundamental investment  policy, from borrowing money in  order
to  purchase securities. In  addition, Emerging Markets  Fund and Latin American
Fund currently are prohibited, pursuant to a non-fundamental investment  policy,
from  purchasing securities  during times when  outstanding borrowings represent
more than 5%  of its assets.  Nevertheless, this  policy may be  changed in  the
future  by a  vote of a  majority of  the Trust's Board  of Trustees.  If a Fund
employs leverage in the future, it would be subject to certain additional risks.
Use of leverage creates an opportunity  for greater growth of capital but  would
exaggerate  any increases or decreases  in the Fund's net  asset value. When the
income and gains on securities purchased with the proceeds of borrowings  exceed
the  costs  of such  borrowings, the  Fund's  earnings or  net asset  value will
increase faster than otherwise would be the case; conversely, if such income and
gains fail to exceed such  costs, the Fund's earnings  or net asset value  would
decline faster than would otherwise be the case.

                         AIM LATIN AMERICAN GROWTH FUND
 
   
Each  Fund may  enter into reverse  repurchase agreements.  A reverse repurchase
agreement is a borrowing transaction in  which a Fund transfers possession of  a
security  to another party, such as a  bank or broker/dealer in return for cash,
and agrees to repurchase  the security in  the future at  an agreed upon  price,
which  includes an interest component. Emerging  Markets Fund also may engage in
"roll" borrowing  transactions  which  involve the  Fund's  sale  of  Government
National  Mortgage Association certificates or  other securities together with a
commitment (for which the Fund may receive  a fee) to purchase similar, but  not
identical,  securities  at  a  future  date. Each  Fund  will  segregate  with a
custodian, cash  or liquid  securities  in an  amount  sufficient to  cover  its
obligations  under "roll" transactions  (for Emerging Markets  Fund) and reverse
repurchase agreements  with  broker/dealers.  No  segregation  is  required  for
reverse repurchase agreements with banks.
    
 
SHORT SALES
The  Fund  may  make short  sales  of  securities, although  it  has  no current
intention of doing so. A short sale is  a transaction in which the Fund sells  a
security  in anticipation that  the market price of  that security will decline.
The Fund may  make short  sales (i)  as a form  of hedging  to offset  potential
declines  in long positions in securities it owns, or anticipates acquiring, and
(ii) in order to maintain portfolio flexibility.
 
   
When a Fund makes a short sale of a security it does not own, it must borrow the
security sold short and  deliver it to the  broker-dealer or other  intermediary
through  which it made the short sale. The Fund  may have to pay a fee to borrow
particular securities  and will  often be  obligated to  pay over  any  payments
received on such borrowed securities.
    
 
   
A  Fund's  obligation to  replace the  borrowed security  when the  borrowing is
called or expires will be secured by collateral deposited with the intermediary.
The Fund will also be required to  deposit collateral with its custodian to  the
extent,  if any, necessary so that the  value of both collateral deposits in the
aggregate is at all times equal to at least 100% of the current market value  of
the  security sold short.  Depending on arrangements  made with the intermediary
from which it borrowed the security regarding payment of any amounts received by
the Fund on  such security,  the Fund may  not receive  any payments  (including
interest) on its collateral deposited with such intermediary.
    
 
   
If  the price of the security sold short increases between the time of the short
sale and the time the Fund replaces the borrowed security, the Fund will incur a
loss; conversely, if the price declines, the Fund will realize a gain. Any  gain
will  be decreased, and any loss  increased, by the transaction costs associated
with the transaction. Although the Fund's gain is limited by the price at  which
it sold the security short, its potential loss is theoretically unlimited.
    
 
   
Neither Emerging Markets Fund nor Latin American Fund will make a short sale if,
after  giving effect to such sale, the market value of the securities sold short
exceeds 25% of the value of its total assets or the Fund's aggregate short sales
of the securities of any  one issuer exceed the lesser  of 2% of the Fund's  net
assets or 2% of the securities of any class of the issuer. Moreover, these Funds
may  engage in short sales only with  respect to securities listed on a national
securities exchange. These Funds may make short sales "against the box"  without
respect to such limitations. In this type of short sale, at the time of the sale
the  Fund  owns  the  security  it  has sold  short  or  has  the  immediate and
unconditional right to acquire at no additional cost the identical security.
    
 
   
Developing Markets Fund may  only make short sales  "against the box." The  Fund
might make a short sale "against the box" in order to hedge against market risks
when  the Sub-adviser believes that the price of a security may decline, causing
a decline in the value of a security owned by the Fund or a security convertible
into or exchangeable for such security. In  such case, any future losses in  the
Fund's  long  position  should be  reduced  by  a gain  in  the  short position.
Conversely, any gain in  the long position  should be reduced by  a loss in  the
short  position. The extent to  which such gains or  losses in the long position
are reduced will depend upon the amount of the securities sold short relative to
the amount of the securities the Fund owns, either directly or indirectly,  and,
in  the  case  where  the  Fund  owns  convertible  securities,  changes  in the
investment values  or conversion  premiums  of such  securities. There  will  be
certain  additional transaction costs  associated with short  sales "against the
box," but the  Fund will endeavor  to offset  these costs with  income from  the
investment of the cash proceeds of short sales.
    
 
TEMPORARY DEFENSIVE STRATEGIES
   
The  Funds may invest in the following  types of money market instruments (i.e.,
debt instruments with less than 12 months remaining until maturity)  denominated
in  U.S. dollars or  other currencies (in  the case of  Latin American Fund, the
currency of any Latin American country): (a) obligations issued or guaranteed by

entities  to promote economic reconstruction or development; (c) finance company
obligations,  corporate  commercial  paper   and  other  short-term   commercial
obligations;  (d)  bank  obligations (including  certificates  of  deposit, time
deposits, demand deposits and  bankers' acceptances); (e) repurchase  agreements
with  respect to the  foregoing; and (f)  other substantially similar short-term
debt securities with comparable characteristics.
 
   
The Funds may  invest in  commercial paper  rated as low  as A-3  by Standard  &
Poor's,  a division of The McGraw-Hill Companies, Inc. ("S&P") or P-3 by Moody's
Investors Service, Inc. ("Moody's") or, if not rated, determined by the  Manager
to be of comparable quality. Obligations rated A-3 and P-3 are considered by S&P
and  Moody's, respectively, to have an acceptable capacity for timely repayment.
However, these securities may be more  vulnerable to adverse effects of  changes
in circumstances than obligations carrying higher designations.
    
 
   
SAMURAI AND YANKEE BONDS
    
   
Subject  to its fundamental investment restrictions, Developing Markets Fund and
Emerging Markets  Fund may  invest in  yen-denominated bonds  sold in  Japan  by
non-Japanese  issuers ("Samurai  bonds"), and  may invest  in dollar-denominated
bonds sold  in  the United  States  by  non-U.S. issuers  ("Yankee  bonds").  As
compared  with bonds  issued in  their countries  of domicile,  such bond issues
normally carry a higher interest  rate but are less  actively traded. It is  the
policy  of each of these  Funds to invest in Samurai  or Yankee bond issues only
after taking into account  considerations of quality and  liquidity, as well  as
yield.  In the  case of Emerging  Markets Fund,  these bonds would  be issued by
governments which are members of  the Organization for Economic Cooperation  and
Development or have AAA ratings.
    
 
   
DEBT CONVERSIONS
    
   
Several Latin American countries have adopted debt conversion programs, pursuant
to  which investors may use external debt  of a country, directly or indirectly,
to make investments in local companies.  The terms of the various programs  vary
from country to country, although each program includes significant restrictions
on  the  application of  the  proceeds received  in  the conversion  and  on the
remittance of  profits on  the investment  and of  the invested  capital.  Latin
American  Fund intends to acquire Sovereign  Debt, as defined in the Prospectus,
to hold and trade in appropriate  circumstances as described in the  Prospectus,
as  well  as to  participate  in Latin  American  debt conversion  programs. The
Sub-adviser  will  evaluate   opportunities  to  enter   into  debt   conversion
transactions  as they arise but does not currently intend to invest more than 5%
of the Fund's assets in such programs.
    
 
PREMIUM SECURITIES
   
Developing Markets Fund  may invest  in income securities  bearing coupon  rates
higher  than prevailing  market rates.  Such "premium"  securities are typically
purchased at prices greater than the principal amounts payable on maturity.  The
Fund  will not amortize the premium paid  for such securities in calculating its
net investment  income.  As  a  result,  in such  cases  the  purchase  of  such
securities  provides the Fund a higher  level of investment income distributable
to shareholders on a current basis than if the Fund purchased securities bearing
current market  rates of  interest. If  securities purchased  by the  Fund at  a
premium  are called or sold  prior to maturity, the Fund  will realize a loss to
the extent the call or sale price is less than the purchase price. Additionally,
the Fund will realize a loss if it holds such securities to maturity.
    
 
INDEXED DEBT SECURITIES
   
Developing Markets Fund may invest in debt securities issued by banks and  other
business entities not located in developing market countries that are indexed to
certain  specific  foreign  currency  exchange rates,  interest  rates  or other
reference rates.  The terms  of  such securities  provide that  their  principal
amount  is  adjusted upwards  or downwards  (but ordinarily  not below  zero) at
maturity to reflect  changes in  the exchange  rate between  two currencies  (or
other  rates) while the obligations are outstanding. While such securities offer
the potential for an  attractive rate of  return, they also  entail the risk  of
loss  of principal. New forms  of such securities continue  to be developed. The
Fund may invest in such securities to the extent consistent with its  investment
objectives.
    
 
STRUCTURED INVESTMENTS
   
Developing  Markets Fund  may invest  a portion  of its  assets in  interests in
entities organized  and operated  solely for  the purpose  of restructuring  the
investment  characteristics  of  Sovereign  Debt.  This  type  of  restructuring
involves the deposit with  or purchase by  an entity, such  as a corporation  or
trust,  of specified instruments (such as  commercial bank loans or Brady Bonds)
and  the  issuance  by  that  entity  of  one  or  more  classes  of  securities
("Structured   Investments")  backed  by,  or  representing  interests  in,  the
underlying instruments.  The cash  flow  on the  underlying instruments  may  be
apportioned  among the newly issued  Structured Investments to create securities
with different investment  characteristics such as  varying maturities,  payment
priorities  and interest  rate provisions, and  the extent of  the payments made
with respect to Structured  Investments is dependent on  the extent of the  cash
flow on the underlying instruments. Because Structured

                         AIM LATIN AMERICAN GROWTH FUND
Investments  of the type in which the  Fund anticipates it will invest typically
involve no credit enhancement, their credit risk generally will be equivalent to
that of the underlying instruments.
 
   
Developing Markets  Fund  is  permitted  to invest  in  a  class  of  Structured
Investments  that is  either subordinated  or not  subordinated to  the right of
payment of  another class.  Subordinated Structured  Investments typically  have
higher   yields  and  present  greater   risks  than  unsubordinated  Structured
Investments.
    
 
   
Certain issuers  of  Structured Investments  may  be deemed  to  be  "investment
companies"  as defined in the  1940 Act. As a  result, Developing Markets Fund's
investment in these Structured  Investments may be  limited by the  restrictions
contained  in  the 1940  Act described  above  under "Investment  Objectives and
Policies -- Investments in  Other Investment Companies." Structured  Investments
are  typically sold in private placement transactions, and there currently is no
active trading market for Structured Investments.
    
 
STRIPPED INCOME SECURITIES
   
Developing Markets Fund may  invest a portion of  its assets in stripped  income
securities,  which are obligations representing an  interest in all or a portion
of the income or  principal components of an  underlying or related security,  a
pool  of securities or  other assets. In  the most extreme  case, one class will
receive all of the interest (the interest  only or "IO" class), while the  other
class  will receive all of the principal (the principal-only or "PO" class). The
market values of stripped income securities tend to be more volatile in response
to changes in interest rates than are conventional income securities.
    
 
FLOATING AND VARIABLE RATE INCOME SECURITIES
   
Developing Markets  Fund may  invest a  portion  of its  assets in  floating  or
variable  rate income securities. Income securities  may provide for floating or
variable rate interest or dividend payments.  The floating or variable rate  may
be determined by reference to a known lending rate, such as a bank's prime rate,
a  certificate of deposit  rate or the  London Inter Bank  Offered Rate (LIBOR).
Alternatively, the  rate may  be determined  through an  auction or  remarketing
process.  The rate also may be indexed to changes in the values of interest rate
or securities indexes, currency exchange rates or other commodities. The  amount
by  which the rate  paid on an income  security may increase  or decrease may be
subject to  periodic  or  lifetime  caps.  Floating  and  variable  rate  income
securities  include securities whose rates vary inversely with changes in market
rates of interest. Such securities may also pay a rate of interest determined by
applying a multiple to the variable rate. The extent of increases and  decreases
in  the value of  securities whose rates  vary inversely with  changes in market
rates of interest generally will be larger than comparable changes in the  value
of  an equal  principal amount  of a fixed  rate security  having similar credit
quality, redemption provisions and maturity.
    
 
SWAPS, CAPS, FLOORS AND COLLARS
   
Developing Markets Fund may enter into  interest rate, currency and index  swaps
and  may purchase or sell related caps,  floors and collars and other derivative
instruments. The  Fund expects  to enter  into these  transactions primarily  to
preserve  a  return or  spread  on a  particular  investment or  portion  of its
portfolio, to protect against currency fluctuations, as a technique for managing
the portfolio's duration  (I.E., the  price sensitivity to  changes in  interest
rates)  or to protect against  any increase in the  price of securities the Fund
anticipates  purchasing  at  a  later  date.  The  Fund  intends  to  use  these
transactions  as hedges and will not sell  interest rate caps, floors or collars
if it does not  own securities or other  instruments providing an income  stream
roughly equivalent to what the Fund may be obligated to pay.
    
 
   
Interest rate swaps involve the exchange by Developing Markets Fund with another
party  of their respective commitments to  pay or receive interest (for example,
an exchange of floating rate payments for fixed rate payments) with respect to a
notional amount of principal. A currency  swap is an agreement to exchange  cash
flows  on a  notional amount  based on  changes in  the values  of the reference
indices.
    
 
The purchase of a cap entitles the  purchaser to receive payments on a  notional
principal  amount from the party selling the  cap to the extent that a specified
index exceeds a predetermined  interest rate. The purchase  of an interest  rate
floor  entitles the purchaser to receive payments on a notional principal amount
from the party  selling the floor  to the  extent that a  specified index  falls
below  a predetermined interest rate  or amount. A collar  is a combination of a
cap and a floor that preserves a certain return within a predetermined range  of
interest rates or values.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use of options, futures contracts  and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
   
        (1) Successful  use  of  most  of these  instruments  depends  upon  the
    Sub-adviser's  ability to  predict movements  of the  overall securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-adviser is experienced in
    the use of these instruments, there can be no assurance that any  particular
    strategy adopted will succeed.
    
 
        (2)  There  might  be  imperfect correlation,  or  even  no correlation,
    between price  movements  of  an  instrument  and  price  movements  of  the
    investments being hedged. For example, if the value of an instrument used in
    a  short hedge  increased by less  than the  decline in value  of the hedged
    investment, the  hedge  would  not  be fully  successful.  Such  a  lack  of
    correlation  might  occur  due to  factors  unrelated  to the  value  of the
    investments being  hedged, such  as speculative  or other  pressures on  the
    markets  in which  the hedging  instrument is  traded. The  effectiveness of
    hedges using hedging  instruments on indices  will depend on  the degree  of
    correlation  between price movements in the index and price movements in the
    investments being hedged.
 
   
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative  effect of unfavorable price  movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity  for gain by  offsetting the positive  effect of favorable price
    movements in the hedged investments. For  example, if a Fund entered into  a
    short  hedge because the Sub-adviser  projected a decline in  the price of a
    security in the Fund's portfolio, and  the price of that security  increased
    instead,  the gain from that increase might by wholly or partially offset by
    a decline in the price of the hedging instrument. Moreover, if the price  of
    the  hedging instrument declined by  more than the increase  in the price of
    the security, the Fund could  suffer a loss. In  either such case, the  Fund
    would have been in a better position had it not hedged at all.
    
 
   
        (4)  As described below, a Fund might  be required to maintain assets as
    "cover," maintain segregated accounts or make margin payments when it  takes
    positions  in  instruments  involving obligations  to  third  parties (i.e.,
    instruments other than purchased options). If the Fund were unable to  close
    out  its positions in such instruments, it  might be required to continue to
    maintain such assets or  accounts or make such  payments until the  position
    expired or matured. The requirements might impair the Fund's ability to sell
    a portfolio security or make an investment at a time when it would otherwise
    be favorable to do so, or require that the Fund sell a portfolio security at
    a  disadvantageous time.  A Fund's  ability to  close out  a position  in an
    instrument prior to  expiration or maturity  depends on the  existence of  a
    liquid secondary market or, in the absence of such a market, the ability and
    willingness  of the other party to the transaction ("contra party") to enter
    into a  transaction  closing  out  the  position.  Therefore,  there  is  no
    assurance  that any position can  be closed out at a  time and price that is
    favorable to the Funds.
    
 
WRITING CALL OPTIONS
   
Each Fund may write (sell) call  options on securities, indices and  currencies.
Call options generally will be written on securities and currencies that, in the
opinion of the Sub-adviser are not expected to make any major price moves in the
near  future  but  that,  over  the  long  term,  are  deemed  to  be attractive
investments for a Fund.
    
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
Style) or on (European Style) a certain  date (the expiration date). So long  as
the  obligation of the writer of a call  option continues, he may be assigned an
exercise notice, requiring him  to deliver the  underlying security or  currency
against  payment  of the  exercise price.  This  obligation terminates  upon the
expiration of the call option, or such earlier time at which the writer  effects
a  closing  purchase  transaction  by purchasing  an  option  identical  to that
previously sold.

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
   
Portfolio securities or currencies on which call options may be written will  be
purchased  solely on the basis of investment considerations consistent with each
Fund's investment objective. When writing a  call option, a Fund, in return  for
the  premium, gives up the  opportunity for profit from  a price increase in the
underlying security or currency above the  exercise price, and retains the  risk
of  loss should the  price of the  security or currency  decline. Unlike one who
owns securities or currencies not  subject to an option,  a Fund has no  control
over  when it may be  required to sell the  underlying securities or currencies,
since most  options  may  be  exercised  at  any  time  prior  to  the  option's
expiration.  If a  call option that  a Fund  has written expires,  the Fund will
realize a gain in the amount of the premium; however, such gain may be offset by
a decline in the market value of the underlying security or currency during  the
option  period. If the call option is exercised, the Fund will realize a gain or
loss from  the  sale of  the  underlying security  or  currency, which  will  be
increased  or  offset by  the  premium received.  The  Funds do  not  consider a
security or currency covered by  a call option to be  "pledged" as that term  is
used  in the  Funds' policies  that limit  the pledging  or mortgaging  of their
assets.
    
 
   
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option  will be exercised and a  Fund will be obligated to
sell the security or currency at less than its market value.
    
 
   
The premium  that  a Fund  receives  for writing  a  call option  is  deemed  to
constitute  the market value of an option.  The premium a Fund will receive from
writing a call option will reflect, among other things, the current market price
of the underlying  investment, the relationship  of the exercise  price to  such
market  price, the historical price volatility of the underlying investment, and
the length of the option period. In determining whether a particular call option
should be  written, the  Sub-adviser  will consider  the reasonableness  of  the
anticipated premium and the likelihood that a liquid secondary market will exist
for those options.
    
 
   
Closing  transactions  will be  effected  in order  to  realize a  profit  on an
outstanding call  option, to  prevent an  underlying security  or currency  from
being  called, or  to permit  the sale of  the underlying  security or currency.
Furthermore, effecting a closing transaction will permit a Fund to write another
call option  on the  underlying security  or currency  with either  a  different
exercise price, expiration date or both.
    
 
   
Each  Fund will pay transaction costs in  connection with the writing of options
and in entering into closing  purchase contracts. Transaction costs relating  to
options  activity normally  are higher  than those  applicable to  purchases and
sales of portfolio securities.
    
 
   
The exercise price of the  options may be below, equal  to or above the  current
market values of the underlying securities or currencies at the time the options
are  written. From time to  time, a Fund may  purchase an underlying security or
currency for delivery in accordance with the exercise of an option, rather  than
delivering  such  security  or  currency  from  its  portfolio.  In  such cases,
additional costs will be incurred.
    
 
   
A Fund will realize a profit or loss from a closing purchase transaction if  the
cost of the transaction is less or more, respectively, than the premium received
from  writing the option. Because increases in the market price of a call option
generally will reflect increases in the market price of the underlying  security
or  currency, any loss resulting from the  repurchase of a call option is likely
to be offset in whole or in  part by appreciation of the underlying security  or
currency owned by the Fund.
    
 
WRITING PUT OPTIONS
   
Each  Fund may write  put options on  securities, indices and  currencies. A put
option gives the  purchaser of  the option  the right  to sell,  and the  writer
(seller)  the  obligation to  buy, the  underlying security  or currency  at the
exercise price at  any time until  (American style) or  on (European style)  the
expiration date. The operation of put options in other respects, including their
related risks and rewards, is identical substantially to that of call options.
    
 
   
A  Fund generally would write put options in circumstances where the Sub-adviser
wishes to purchase the underlying security or currency for the Fund's  portfolio
at  a price lower than the current market  price of the security or currency. In
such event, the Fund would write a put option at an exercise price that, reduced
by the premium received on the option, reflects the lower price it is willing to
pay. Since the Fund would also receive interest on debt securities or currencies
maintained to cover the  exercise price of the  option, this technique could  be
used to enhance current return during periods of market uncertainty. The risk in
such  a transaction would be that the market price of the underlying security or
currency would decline below the exercise price less the premium received.

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
Writing put options can serve as a  limited long hedge because increases in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
depreciates  to a price lower than the exercise  price of the put option, it can
be expected that the put option will be exercised and the Fund will be obligated
to sell the security or currency at more than its market value.
 
PURCHASING PUT OPTIONS
   
Each Fund may purchase put options on securities, indices and currencies. As the
holder of a  put option,  a Fund  would have the  right to  sell the  underlying
security or currency at the exercise price at any time until (American style) or
on  (European style)  the expiration  date. A Fund  may enter  into closing sale
transactions with  respect to  such options,  exercise them  or permit  them  to
expire.
    
 
   
A  Fund  may  purchase  a  put option  on  an  underlying  security  or currency
("protective put") owned by the Fund  to protect against an anticipated  decline
in  the value  of the  security or  currency. Such  protection is  provided only
during the life  of the  put option  when the  Fund, as  the holder  of the  put
option,  is able to sell the underlying security or currency at the put exercise
price regardless of  any decline in  the underlying security's  market price  or
currency's  exchange  value.  The  premium  paid  for  the  put  option  and any
transaction costs would reduce any  profit otherwise available for  distribution
when the security or currency is eventually sold.
    
 
   
A  Fund also may purchase put  options at a time when  the Fund does not own the
underlying security or  currency. By  purchasing put  options on  a security  or
currency it does not own, the Fund seeks to benefit from a decline in the market
price of the underlying security or currency. If the put option is not sold when
it  has remaining value, and  if the market price  of the underlying security or
currency remains equal to or greater than the exercise price during the life  of
the  put option, the Fund will lose its  entire investment in the put option. In
order for the purchase of a put option to be profitable, the market price of the
underlying security or  currency must  decline sufficiently  below the  exercise
price  to cover the premium and transaction costs, unless the put option is sold
in a closing sale transaction.
    
 
PURCHASING CALL OPTIONS
   
Each Fund may purchase  call options on securities,  indices and currencies.  As
the  holder  of a  call option,  a Fund  would  have the  right to  purchase the
underlying security  or  currency  at  the exercise  price  at  any  time  until
(American  style) or on (European  style) the expiration date.  A Fund may enter
into closing sale transactions  with respect to such  options, exercise them  or
permit them to expire.
    
 
   
Call  options  may be  purchased  by a  Fund for  the  purpose of  acquiring the
underlying security or currency for its portfolio. Utilized in this fashion, the
purchase of  call options  would enable  the  Fund to  acquire the  security  or
currency  at the  exercise price of  the call  option plus the  premium paid. At
times, the net cost of acquiring the security or currency in this manner may  be
less  than  the  cost  of  acquiring the  security  or  currency  directly. This
technique also may be useful to a Fund in purchasing a large block of securities
that would be more difficult to acquire  by direct market purchases. So long  as
it  holds such a  call option, rather  than the underlying  security or currency
itself, the  Fund is  partially protected  from any  unexpected decline  in  the
market  price of the underlying  security or currency and,  in such event, could
allow the call  option to expire,  incurring a loss  only to the  extent of  the
premium paid for the option.
    
 
   
A  Fund also may purchase call options on underlying securities or currencies it
owns to avoid realizing losses that would  result in a reduction of its  current
return.  For example, where  a Fund has  written a call  option on an underlying
security or currency having a current market  value below the price at which  it
purchased the security or currency, an increase in the market price could result
in  the exercise of the call option written by the Fund and the realization of a
loss on  the  underlying  security  or currency.  Accordingly,  the  Fund  could
purchase  a call option on the same underlying security or currency, which could
be exercised to fulfill the Fund's  delivery obligations under its written  call
(if  it is exercised). This  strategy could allow the  Fund to avoid selling the
portfolio security  or  currency at  a  time when  it  has an  unrealized  loss;
however,  the Fund would have to pay a  premium to purchase the call option plus
transaction costs.
    
 
   
Aggregate premiums paid for put and call options will not exceed 5% of a  Fund's
total assets at the time of purchase.
    
 
   
Each  Fund may attempt to accomplish objectives similar to those involved in its
use of Forward Contracts by purchasing put or call options on currencies. A  put
option  gives a Fund as  purchaser the right (but not  the obligation) to sell a
specified amount of currency at the  exercise price at any time until  (American
style) or on (European style) the expiration date. A call option gives a Fund as
purchaser  the right (but not the obligation)  to purchase a specified amount of
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style)  the expiration  date. A  Fund might  purchase a  currency put
option, for example, to protect itself against a decline in the dollar value  of
a currency in which it holds or

anticipates  holding securities. If the  currency's value should decline against
the dollar, the loss in currency value should be offset, in whole or in part, by
an increase in the value of the put. If the value of the currency instead should
rise against the dollar, any gain to the Fund would be reduced by the premium it
had paid for  the put option.  A currency  call option might  be purchased,  for
example,  in anticipation of, or to protect against, a rise in the value against
the dollar of a currency in which a Fund anticipates purchasing securities.
    
 
   
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing corporation), and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates.  A Fund  will not purchase  an OTC  option unless it  believes that daily
valuations for  such options  are readily  obtainable. OTC  options differ  from
exchange-traded options in that OTC options are transacted with dealers directly
and   not  through  a  clearing   corporation  (which  guarantees  performance).
Consequently, there  is  a risk  of  non-performance  by the  dealer.  Since  no
exchange  is involved, OTC options are valued on  the basis of an average of the
last bid prices obtained from dealers,  unless a quotation from only one  dealer
is  available, in which case only that dealer's  price will be used. In the case
of OTC options, there can  be no assurance that  a liquid secondary market  will
exist for any particular option at any specific time.
    
 
   
The  staff of the SEC considers purchased OTC options to be illiquid securities.
A Fund may also sell OTC options and, in connection therewith, segregate  assets
or  cover its obligations with  respect to OTC options  written by the Fund. The
assets used as  cover for OTC  options written  by the Fund  will be  considered
illiquid unless the OTC options are sold to qualified dealers who agree that the
Fund may repurchase any OTC option it writes at a maximum price to be calculated
by  a formula  set forth in  the option agreement.  The cover for  an OTC option
written subject  to this  procedure would  be considered  illiquid only  to  the
extent that the maximum repurchase price under the formula exceeds the intrinsic
value of the option.
    
 
   
A Fund's ability to establish and close out positions in exchange-listed options
depends  on the existence of  a liquid market. Each  Fund intends to purchase or
write only those exchange-traded options for which there appears to be a  liquid
secondary  market. However, there  can be no  assurance that such  a market will
exist at any particular time. Closing  transactions can be made for OTC  options
only  by negotiating directly with  the contra party or  by a transaction in the
secondary market if any such market  exists. Although each Fund will enter  into
OTC options only with contra parties that are expected to be capable of entering
into  closing transactions with the  Fund, there is no  assurance that the Funds
will in fact be able  to close out an OTC  option position at a favorable  price
prior  to expiration.  In the event  of insolvency  of the contra  party, a Fund
might be unable to  close out an OTC  option position at any  time prior to  its
expiration.
    
 
INDEX OPTIONS
   
Puts and calls on indices are similar to puts and calls on securities or futures
contracts  except that all settlements  are in cash and  gain or loss depends on
changes in the index in question (and thus on price movements in the  securities
market  or a particular market sector  generally) rather than on price movements
in individual securities or futures contracts. When  a Fund writes a call on  an
index,  it receives a premium and agrees that, prior to the expiration date, the
purchaser of the call, upon exercise of the call, will receive from the Fund  an
amount of cash if the closing level of the index upon which the call is based is
greater  than the exercise price of the call. The amount of cash is equal to the
difference between the closing price of the index and the exercise price of  the
call  times a specified multiple (the  "multiplier"), which determines the total
dollar value for each point  of such difference. When a  Fund buys a call on  an
index,  it  pays a  premium and  has  the same  rights as  to  such call  as are
indicated above. When a Fund buys a put  on an index, it pays a premium and  has
the  right, prior to the expiration date, to require the seller of the put, upon
the Fund's exercise of the put, to deliver to the Fund an amount of cash if  the
closing level of the index upon which the put is based is less than the exercise
price  of the  put, which  amount of  cash is  determined by  the multiplier, as
described above for calls. When a Fund writes  a put on an index, it receives  a
premium  and  the purchaser  has the  right,  prior to  the expiration  date, to
require the Fund  to deliver to  it an amount  of cash equal  to the  difference
between  the  closing  level of  the  index  and the  exercise  price  times the
multiplier, if the closing level is less than the exercise price.
    
 
   
The risks  of  investment  in index  options  may  be greater  than  options  on
securities. Because index options are settled in cash, when a Fund writes a call
on  an  index  it  cannot  provide  in  advance  for  its  potential  settlement
obligations by  acquiring and  holding  the underlying  securities. A  Fund  can
offset  some of the  risk of writing a  call index option  position by holding a
diversified portfolio of  securities similar  to those on  which the  underlying
index is based. However, a Fund

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
cannot,  as a practical matter, acquire  and hold a portfolio containing exactly
the same securities as underlie  the index and, as a  result, bears a risk  that
the value of the securities held will vary from the value of the index.
 
   
Even if a Fund could assemble a securities portfolio that exactly reproduced the
composition  of the underlying index, it still would not be fully covered from a
risk standpoint because of the "timing risk" inherent in writing index  options.
When  an  index option  is  exercised, the  amount of  cash  that the  holder is
entitled to receive is determined by  the difference between the exercise  price
and  the closing index level  on the date when the  option is exercised. As with
other kinds of options, a  Fund, as the call writer,  will not know that it  has
been  assigned until the next business day at the earliest. The time lag between
exercise and notice of assignment poses no risk for the writer of a covered call
on a  specific underlying  security, such  as common  stock, because  there  the
writer's  obligation is to deliver the underlying security, not to pay its value
as of  a  fixed time  in  the past.  So  long as  the  writer already  owns  the
underlying  security,  it  can  satisfy  its  settlement  obligations  by simply
delivering it, and the risk that its value may have declined since the  exercise
date  is borne by the  exercising holder. In contrast, even  if the writer of an
index call holds securities that exactly match the composition of the underlying
index, it will not be able  to satisfy its assignment obligations by  delivering
those  securities against  payment of  the exercise  price. Instead,  it will be
required to  pay cash  in an  amount based  on the  closing index  value on  the
exercise  date; and by the  time it learns that it  has been assigned, the index
may have declined, with a corresponding  decline in the value of its  securities
portfolio.  This "timing risk" is an inherent limitation on the ability of index
call writers to cover their risk exposure by holding securities positions.
    
 
   
If a Fund purchases an  index option and exercises  it before the closing  index
value  for  that day  is  available, it  runs  the risk  that  the level  of the
underlying index may subsequently change. If such a change causes the  exercised
option to fall out-of-the-money, the Fund will be required to pay the difference
between  the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.
    
 
   
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES
    
   
Each Fund may enter  into interest rate or  currency futures contracts, and  may
enter  into stock index  futures contracts (collectively,  "Futures" or "Futures
Contracts"), as a hedge against changes in prevailing levels of interest  rates,
currency  exchange rates or  stock prices in order  to establish more definitely
the effective return on securities or currencies held or intended to be acquired
by the Fund. A  Fund's transactions may  include sales of  Futures as an  offset
against  the effect  of expected increases  in interest rates,  and decreases in
currency exchange rates and stock prices, and purchases of Futures as an  offset
against  the effect  of expected  declines in  interest rates,  and increases in
currency exchange rates and stock prices.
    
 
   
A Fund  will  only enter  into  Futures Contracts  that  are traded  on  futures
exchanges  and are  standardized as  to maturity  date and  underlying financial
instrument. Futures  exchanges and  trading  thereon in  the United  States  are
regulated  under the  Commodity Exchange  Act by  the Commodity  Futures Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
    
 
   
Although techniques other than sales and purchases of Futures Contracts could be
used to reduce a  Fund's exposure to interest  rate, currency exchange rate  and
stock  market  fluctuations, a  Fund  may be  able  to hedge  its  exposure more
effectively and at a lower cost through using Futures Contracts.
    
 
A Futures Contract provides  for the future  sale by one  party and purchase  by
another party of a specified amount of a specific financial instrument (security
or  currency) for  a specified price  at a  designated date, time  and place. An
index Futures Contract provides for the delivery, at a designated date, time and
place, of  an amount  of  cash equal  to a  specified  dollar amount  times  the
difference  between the index value at the  close of trading on the contract and
the price  at which  the  Futures Contract  is  originally struck;  no  physical
delivery  of the  securities comprising  the index  is made.  Brokerage fees are
incurred when a Futures Contract is bought or sold, and margin deposits must  be
maintained at all times the Futures Contract is outstanding.
 
   
Although  Futures Contracts typically require future delivery of and payment for
financial instruments or  currencies, Futures Contracts  are usually closed  out
before  the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering  into an offsetting Futures  Contract purchase or  sale,
respectively,   for  the  same  aggregate  amount  of  the  identical  financial
instrument or currency and  the same delivery date.  If the offsetting  purchase
price  is less than  the original sale price,  a Fund realizes a  gain; if it is
more, a Fund realizes a loss. Conversely,  if the offsetting sale price is  more
than  the original purchase  price, a Fund realizes  a gain; if  it is less, the
Fund realizes  a loss.  The transaction  costs must  also be  included in  these
calculations.  There can be no  assurance, however, that a  Fund will be able to
enter into an offsetting

transaction with respect to a particular Futures Contract at a particular  time.
If  a Fund is  not able to enter  into an offsetting  transaction, the Fund will
continue to be required to maintain the margin deposits on the Futures Contract.
    
 
As an example of an offsetting transaction, the contractual obligations  arising
from  the sale of one Futures Contract of September Deutschemarks on an exchange
may be  fulfilled at  any time  before delivery  under the  Futures Contract  is
required  (I.E., on a specified date in  September, the "delivery month") by the
purchase of  another Futures  Contract of  September Deutschemarks  on the  same
exchange. In such instance the difference between the price at which the Futures
Contract  was  sold  and  the  price paid  for  the  offsetting  purchase, after
allowance for transaction costs, represents the profit or loss to the Fund.
 
   
Each Fund's Futures transactions will be entered into for hedging purposes only;
that is, Futures  Contracts will be  sold to  protect against a  decline in  the
price  of securities or currencies that the Fund owns, or Futures Contracts will
be purchased to protect the Fund against an increase in the price of  securities
or currencies it has committed to purchase or expects to purchase.
    
 
   
"Margin"  with respect to Futures Contracts is  the amount of funds that must be
deposited by a Fund  in order to  initiate Futures trading  and to maintain  the
Fund's  open  positions in  Futures Contracts.  A margin  deposit made  when the
Futures Contract is  entered into  ("initial margin")  is intended  to assure  a
Fund's  performance  under  the  Futures Contract.  The  margin  required  for a
particular Futures Contract is set by the exchange on which the Futures Contract
is traded and may be  modified significantly from time  to time by the  exchange
during the term of the Futures Contract.
    
 
   
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission merchant through which a Fund entered into the Futures Contract  will
be  made on a daily  basis as the price of  the underlying security, currency or
index fluctuates making the  Futures Contract more or  less valuable, a  process
known as marking-to-market.
    
 
   
    RISKS  OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts are
volatile and  are influenced  by,  among other  things, actual  and  anticipated
changes  in  interest rates  and currency  exchange rates,  and in  stock market
movements, which  in turn  are  affected by  fiscal  and monetary  policies  and
national and international political and economic events.
    
 
   
There  is a risk of  imperfect correlation between changes  in prices of Futures
Contracts and prices of the securities or currencies in a Fund's portfolio being
hedged. The degree  of imperfection  of correlation  depends upon  circumstances
such  as: variations in speculative market demand for Futures and for securities
or  currencies,  including   technical  influences  in   Futures  trading;   and
differences  between the financial instruments  being hedged and the instruments
underlying the standard Futures Contracts  available for trading. A decision  of
whether,  when,  and  how to  hedge  involves  skill and  judgment,  and  even a
well-conceived hedge may be  unsuccessful to some  degree because of  unexpected
market behavior or interest or currency rate trends.
    
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and options on Futures Contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a Futures  Contract
or option may vary either up or down from the previous day's settlement price at
the  end  of a  trading session.  Once the  daily  limit has  been reached  in a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a particular trading day and therefore does not limit potential losses,  because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and  option  prices  have occasionally  moved  to  the daily  limit  for several
consecutive trading days with  little or no  trading, thereby preventing  prompt
liquidation of positions and subjecting some traders to substantial losses.
 
   
If  a Fund were unable to liquidate a  Futures or option on Futures position due
to the absence of a liquid secondary  market or the imposition of price  limits,
it  could incur  substantial losses.  The Fund would  continue to  be subject to
market risk with respect  to the position.  In addition, except  in the case  of
purchased    options,    the    Fund    would    continue    to    be   required

to make daily variation  margin payments and might  be required to maintain  the
position  being hedged by the Future or option or to maintain cash or securities
in a segregated account.
 
   
Certain characteristics  of the  Futures  market might  increase the  risk  that
movements  in the prices  of Futures Contracts  or options on  Futures might not
correlate perfectly  with  movements in  the  prices of  the  investments  being
hedged.  For example,  all participants  in the  Futures and  options on Futures
markets are subject to  daily variation margin calls  and might be compelled  to
liquidate  Futures  or  options on  Futures  positions whose  prices  are moving
unfavorably to avoid being  subject to further  calls. These liquidations  could
increase  price  volatility  of the  instruments  and distort  the  normal price
relationship between the Futures  or options and  the investments being  hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous  than  margin requirements  in the  securities  markets, there  might be
increased  participation   by  speculators   in   the  Futures   markets.   This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading"  and other  investment strategies  might result  in
temporary price distortions.
    
 
OPTIONS ON FUTURES CONTRACTS
Options  on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the  premium paid,  to  assume a  position in  a  Futures Contract  (a  long
position if the option is a call and a short position if the option is a put) at
a  specified exercise price  at any time  during the period  of the option. Upon
exercise of the option, the  delivery of the Futures  position by the writer  of
the  option to the holder  of the option will be  accompanied by delivery of the
accumulated balance in the writer's Futures margin account, which represents the
amount by which the market price  of the Futures Contract, at exercise,  exceeds
(in  the case of  a call) or  is less than (in  the case of  a put) the exercise
price of the option on  the Futures Contract. If an  option is exercised on  the
last trading day prior to the expiration date of the option, the settlement will
be  made entirely in cash equal to  the difference between the exercise price of
the option and  the closing level  of the securities,  currencies or index  upon
which  the  Futures Contract  is  based on  the  expiration date.  Purchasers of
options who fail to exercise their options  prior to the exercise date suffer  a
loss of the premium paid.
 
The  purchase of  call options  on Futures can  serve as  a long  hedge, and the
purchase of put  options on Futures  can serve  as a short  hedge. Writing  call
options  on Futures can serve as a  limited short hedge, and writing put options
on Futures can serve as a limited  long hedge, using a strategy similar to  that
used for writing options on securities, foreign currencies or indices.
 
   
If a Fund writes an option on a Futures Contract, it will be required to deposit
initial   and  variation  margin  pursuant  to  requirements  similar  to  those
applicable to Futures Contracts. Premiums received from the writing of an option
on a Futures Contract are included in the initial margin deposit.
    
 
   
A Fund may seek to  close out an option position  by selling an option  covering
the  same Futures  Contract and  having the  same exercise  price and expiration
date. The  ability to  establish and  close  out positions  on such  options  is
subject to the maintenance of a liquid secondary market.
    
 
LIMITATIONS  ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS ON
CURRENCIES
   
To the extent  that a  Fund enters into  Futures Contracts,  options on  Futures
Contracts,  and  options  on  foreign  currencies  traded  on  a  CFTC-regulated
exchange, in each case other than for BONA FIDE hedging purposes (as defined  by
the CFTC), the aggregate initial margin and premiums required to establish those
positions  (excluding the amount  by which options  are "in-the-money") will not
exceed 5% of the  liquidation value of the  Fund's portfolio, after taking  into
account  unrealized profits and unrealized losses  on any contracts the Fund has
entered  into.  In   general,  a   call  option   on  a   Futures  Contract   is
"in-the-money"if  the  value  of  the underlying  Futures  Contract  exceeds the
strike, i.e., exercise, price of the call; a put option on a Futures Contract is
"in-the-money" if the value  of the underlying Futures  Contract is exceeded  by
the strike price of the put. This guideline may be modified by the Trust's Board
of  Trustees  without a  shareholder vote.  This limitation  does not  limit the
percentage of the Fund's assets at risk to 5%.
    
 
FORWARD CONTRACTS
   
A Forward Contract is an obligation, usually arranged with a commercial bank  or
other  currency dealer, to purchase or  sell a currency against another currency
at a future  date and price  as agreed upon  by the parties.  A Fund either  may
accept or make delivery of the currency at the maturity of the Forward Contract.
The  Fund may also, if its contra party  agrees, prior to maturity, enter into a
closing transaction involving the purchase or sale of an offsetting contract.

                         AIM LATIN AMERICAN GROWTH FUND
 
   
A Fund  engages in  forward  currency transactions  in  anticipation of,  or  to
protect  itself against,  fluctuations in  exchange rates.  A Fund  might sell a
particular  foreign  currency  forward,  for   example,  when  it  holds   bonds
denominated  in a  foreign currency but  anticipates, and seeks  to be protected
against, a decline in the currency against the U.S. dollar. Similarly, the  Fund
might  sell the  U.S. dollar  forward when  it holds  bonds denominated  in U.S.
dollars but anticipates,  and seeks to  be protected against,  a decline in  the
U.S.  dollar relative  to other currencies.  Further, the Fund  might purchase a
currency forward  to "lock  in"  the price  of  securities denominated  in  that
currency that it anticipates purchasing.
    
 
   
Forward  Contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement and no commissions are charged  at
any  stage for  trades. Each  Fund will enter  into such  Forward Contracts with
major U.S. or  foreign banks and  securities or currency  dealers in  accordance
with the guidelines approved by the Trust's Board of Trustees.
    
 
   
Each  Fund  may enter  into Forward  Contracts either  with respect  to specific
transactions or  with respect  to the  Fund's portfolio  positions. The  precise
matching  of the Forward  Contract amounts and the  value of specific securities
generally will not be  possible because the future  value of such securities  in
foreign currencies will change as a consequence of market movements in the value
of  those securities between the  date the Forward Contract  is entered into and
the date it matures.  Accordingly, it may  be necessary for  a Fund to  purchase
additional  foreign  currency on  the  spot (I.E.,  cash)  market (and  bear the
expense of such purchase) if the market  value of the security is less than  the
amount of foreign currency the Fund is obligated to deliver and if a decision is
made to sell the security and make delivery of the foreign currency. Conversely,
it  may be necessary to sell on the spot market some of the foreign currency the
Fund is  obligated to  deliver.  The projection  of short-term  currency  market
movements  is extremely difficult, and the  successful execution of a short-term
hedging strategy is highly  uncertain. Forward Contracts  involve the risk  that
anticipated  currency movements will not be predicted accurately, causing a Fund
to sustain losses on these contracts and transaction costs.
    
 
   
At or before  the maturity  of a  Forward Contract requiring  a Fund  to sell  a
currency,  the  Fund either  may  sell a  portfolio  security and  use  the sale
proceeds to make delivery of the currency or retain the security and offset  its
contractual  obligation to deliver the currency  by purchasing a second contract
pursuant to which  the Fund will  obtain, on  the same maturity  date, the  same
amount  of the currency that  it is obligated to  deliver. Similarly, a Fund may
close out a Forward  Contract requiring it to  purchase a specified currency  by
entering  into a second  contract, if its  contra party agrees,  entitling it to
sell the same  amount of the  same currency on  the maturity date  of the  first
contract.  The Fund would  realize a gain or  loss as a  result of entering into
such an offsetting Forward Contract under either circumstance to the extent  the
exchange  rate  or  rates  between the  currencies  involved  moved  between the
execution dates of the first contract and the offsetting contract.
    
 
   
The cost to a Fund of engaging in Forward Contracts varies with factors such  as
the  currencies  involved, the  length  of the  contract  period and  the market
conditions then prevailing. Because Forward  Contracts usually are entered  into
on  a principal basis, no  fees or commissions are  involved. The use of Forward
Contracts does  not  eliminate fluctuations  in  the prices  of  the  underlying
securities  a Fund owns or  intends to acquire, but it  does establish a rate of
exchange in advance. In addition, while Forward Contract sales limit the risk of
loss due to a decline in the value of the hedged currencies, they also limit any
potential gain that might result should the value of the currencies increase.
    
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
   
Each Fund may use options on foreign currencies, Futures on foreign  currencies,
options  on Futures on foreign currencies and Forward Contracts to hedge against
movements in the values of the foreign currencies in which the Fund's securities
are denominated. Such currency hedges can  protect against price movements in  a
security that a Fund owns or intends to acquire that are attributable to changes
in  the value of  the currency in which  it is denominated.  Such hedges do not,
however, protect against price movements in the securities that are attributable
to other causes.
    
 
   
A Fund might seek to hedge against changes in the value of a particular currency
when no Futures Contract, Forward Contract or option involving that currency  is
available  or  one  of  such  contracts is  more  expensive  than  certain other
contracts. In  such cases,  a Fund  may hedge  against price  movements in  that
currency  by  entering  into  a  contract  on  another  currency  or  basket  of
currencies, the values of  which the Sub-adviser believes  will have a  positive
correlation  to the value of the currency  being hedged. The risk that movements
in the price of the contract will not correlate perfectly with movements in  the
price of the currency being hedged is magnified when this strategy is used.
    
 
The value of Futures Contracts, options on Futures Contracts, Forward Contracts,
and  options  on  foreign currencies  depends  on  the value  of  the underlying
currency relative  to the  U.S. dollar.  Because foreign  currency  transactions

occurring  in the  interbank market  might involve  substantially larger amounts
than those  involved in  the  use of  Futures  Contracts, Forward  Contracts  or
options,  a  Fund  could be  disadvantaged  by  dealing in  the  odd  lot market
(generally  consisting  of  transactions  of  less  than  $1  million)  for  the
underlying  foreign currencies at prices that  are less favorable than for round
lots.
    
 
There is no systematic reporting of last sale information for foreign currencies
or any  regulatory requirements  that quotations  available through  dealers  or
other market sources be firm or revised on a timely basis. Quotation information
generally  is representative of very large  transactions in the interbank market
and thus  might not  reflect  odd-lot transactions  where  rates might  be  less
favorable.   The   interbank  market   in  foreign   currencies  is   a  global,
round-the-clock market. To the  extent the U.S. options  or Futures markets  are
closed  while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that  cannot
be  reflected in  the markets  for the Futures  contracts or  options until they
reopen.
 
   
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies might  be required  to  take place  within  the country  issuing  the
underlying  currency. Thus, a Fund might be  required to accept or make delivery
of the  underlying foreign  currency  in accordance  with  any U.S.  or  foreign
regulations  regarding the maintenance  of foreign banking  arrangements by U.S.
residents and might be  required to pay any  fees, taxes and charges  associated
with such delivery assessed in the issuing country.
    
 
COVER
   
Transactions  using Forward Contracts, Futures Contracts and options (other than
options purchased by a Fund) expose the Fund to an obligation to another  party.
No  Fund will  enter into  any such  transactions unless  it owns  either (1) an
offsetting ("covered")  position in  securities, currencies,  or other  options,
Forward  Contracts or Futures Contracts, or (2) cash, receivables and short-term
debt securities with  a value  sufficient at all  times to  cover its  potential
obligations not covered as provided in (1) above. The Funds will comply with SEC
guidelines  regarding  cover for  these instruments  and,  if the  guidelines so
require, set aside cash or liquid securities.
    
 
   
Assets used as cover or  held in a segregated account  cannot be sold while  the
position  in the corresponding  Forward Contract, Futures  Contract or option is
open, unless they are replaced with other appropriate assets. If a large portion
of a Fund's assets are  used for cover or otherwise  set aside, it could  affect
portfolio  management or the Fund's ability to meet redemption requests or other
current obligations.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
   
Developing Markets Fund and Emerging Markets Fund  each may invest up to 15%  of
its net assets, and Latin American Fund up to 10% of its net assets, in illiquid
securities.  Securities may be  considered illiquid if  a Fund cannot reasonably
expect within seven days  to sell the security  for approximately the amount  at
which  the Fund values such securities. The sale of illiquid securities, if they
can be  sold at  all, generally  will require  more time  and result  in  higher
brokerage  charges or dealer discounts and  other selling expenses than the sale
of liquid securities, such as securities eligible for trading on U.S. securities
exchanges or in  the over-the-counter markets.  Moreover, restricted  securities
which may be illiquid for purposes of this limitation, often sell, if at all, at
a  price lower than similar  securities that are not  subject to restrictions on
resale.
    
 
   
Illiquid securities include those that are subject to restrictions contained  in
the  securities laws  of other  countries. However,  securities that  are freely
marketable in the country  where they are principally  traded, but would not  be
freely  marketable in the United States,  will not be considered illiquid. Where
registration is required,  a Fund may  be obligated to  pay all or  part of  the
registration  expenses and a considerable period  may elapse between the time of
the decision to sell and the time the  Fund may be permitted to sell a  security
under  an effective  registration statement. If,  during such  a period, adverse
market conditions were to develop, the Fund might obtain a less favorable  price
than prevailed when it decided to sell.

                         AIM LATIN AMERICAN GROWTH FUND
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under the Securities Act of 1933, as amended ("1933 Act"), including
private placements, repurchase agreements, commercial paper, foreign  securities
and corporate bonds and notes. These instruments are often restricted securities
because  the  securities are  sold in  transactions not  requiring registration.
Institutional investors generally will not seek to sell these instruments to the
general  public,  but  instead  will   often  depend  either  on  an   efficient
institutional market in which such unregistered securities can be readily resold
or  on an issuer's ability to honor  a demand for repayment. Therefore, the fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
   
Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the  1933 Act  for resales  of certain  securities to qualified
institutional buyers.  Institutional  markets  for  restricted  securities  have
developed  as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to  satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance  and  settlement of  unregistered securities  of domestic  and foreign
issuers, such as  the PORTAL  System sponsored  by the  National Association  of
Securities  Dealers,  Inc.  An insufficient  number  of  qualified institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a Fund,  however, could  affect adversely  the marketability  of such  portfolio
securities  and the Fund might be unable  to dispose of such securities promptly
or at favorable prices.
    
 
   
With respect  to  liquidity  determinations  generally,  the  Trust's  Board  of
Trustees  has  the  ultimate  responsibility  for  determining  whether specific
securities, including restricted securities pursuant to Rule 144A under the 1933
Act, are liquid  or illiquid.  The Board has  delegated the  function of  making
day-to-day  determinations of  liquidity to  the Sub-adviser  in accordance with
procedures approved by the Board. The Sub-adviser takes into account a number of
factors in reaching liquidity decisions, including (i) the frequency of  trading
in  the security, (ii) the  number of dealers who  make quotes for the security,
(iii) the  number  of dealers  who  have undertaken  to  make a  market  in  the
security,  (iv) the number of  other potential purchasers and  (v) the nature of
the security and  how trading is  effected (e.g.,  the time needed  to sell  the
security,  how  offers  are  solicited  and  the  mechanics  of  transfer).  The
Sub-adviser monitors the liquidity  of securities in  each Fund's portfolio  and
periodically  reports  such  determinations  to  the  Board.  If  the  liquidity
percentage restriction of a Fund is satisfied at the time of investment, a later
increase in the  percentage of illiquid  securities held by  the Fund  resulting
from  a change in market value or assets will not constitute a violation of that
restriction. If  as  a  result of  a  change  in market  value  or  assets,  the
percentage  of illiquid securities held by a Fund increases above the applicable
limit, the Sub-adviser will take appropriate steps to bring the aggregate amount
of illiquid assets back within the prescribed limitations as soon as  reasonably
practicable, taking into account the effect of any disposition on the Fund.
    
 
FOREIGN SECURITIES
   
    POLITICAL,  SOCIAL AND ECONOMIC  RISKS. Investing in  securities of non-U.S.
companies may entail additional risks due to the potential political, social and
economic instability  of  certain  countries and  the  risks  of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment, convertibility of currencies into  U.S. dollars and on  repatriation
of  capital invested.  In the  event of  such expropriation,  nationalization or
other confiscation by any  country, a Fund could  lose its entire investment  in
any such country.
    
 
In  addition, even  though opportunities  for investment  may exist  in emerging
markets, any change in  the leadership or policies  of the governments of  those
countries  or  in  the leadership  or  policies  of any  other  government which
exercises a significant influence over  those countries, may halt the  expansion
of  or reverse the  liberalization of foreign  investment policies now occurring
and thereby eliminate any investment opportunities which may currently exist.
 
   
Investors should note that upon the accession to power of authoritarian regimes,
the governments of a number of Latin American countries previously  expropriated
large  quantities of  real and personal  property similar to  the property which
will be represented  by the  securities purchased by  the Funds.  The claims  of
property  owners against those governments were never finally settled. There can
be no assurance  that any property  represented by securities  purchased by  the
Funds  will not also be expropriated, nationalized, or otherwise confiscated. If
such confiscation were to occur, the Funds could lose their entire investment in
such countries. The Funds' investments would similarly be adversely affected  by
exchange control regulation in any of those countries.
    
 
   
    RELIGIOUS  AND ETHNIC  STABILITY. Certain countries  in which  the Funds may
invest  may  have  groups  that  advocate  radical  religious  or  revolutionary
philosophies or support ethnic independence. Any disturbance on the part of such
individuals could carry the potential for widespread destruction or confiscation
of  property owned by individuals and entities foreign to such country and could
cause the loss of a Fund's  investment in those countries. Instability may  also
result from, among

                         AIM LATIN AMERICAN GROWTH FUND
   
other things, (i) authoritarian governments or military involvement in political
and   economic   decision-making,  including   changes  in   government  through
extra-constitutional means,  (ii) popular  unrest  associated with  demands  for
improved  political, economic and social  conditions and (iii) hostile relations
with neighboring  or  other  countries.  Such  political,  social  and  economic
instability  could disrupt  the principal financial  markets in  which the Funds
invest and adversely affect the value of the Funds' assets.
    
 
   
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity markets, by foreign entities such as the Funds. These  restrictions
or  controls may at times limit or preclude investment in certain securities and
may increase the cost and expenses of the Funds. For example, certain  countries
require prior governmental approval before investments by foreign persons may be
made  or may limit the  amount of investment by  foreign persons in a particular
company, or limit the investment by foreign persons to only a specific class  of
securities of a company that may have less advantageous terms than securities of
the company available for purchase by nationals. Moreover, the national policies
of  certain  countries  may  restrict  investment  opportunities  in  issuers or
industries deemed sensitive to national  interests. In addition, some  countries
require governmental approval for the repatriation of investment income, capital
or  the  proceeds  of securities  sales  by  foreign investors.  If  there  is a
deterioration in a country's balance of payments or for other reasons, a country
may impose restrictions on foreign  capital remittances abroad. The Funds  could
be  adversely  affected  by delays  in,  or  a refusal  to  grant,  any required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
    
 
   
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that  differ in some  cases significantly from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting principles. Most  of the securities held  by the Funds  will
not  be registered with the  SEC or regulators of  any foreign country, nor will
the issuers thereof be subject to the SEC's reporting requirements. Thus,  there
will be less available information concerning most foreign issuers of securities
held  by the Funds than is available concerning U.S. issuers. In instances where
the financial statements of an issuer  are not deemed to reflect accurately  the
financial  situation of the issuer, the  Sub-adviser will take appropriate steps
to evaluate the proposed investment, which may include on-site inspection of the
issuer, interviews  with  its  management and  consultations  with  accountants,
bankers  and other specialists.  There is substantially  less publicly available
information about foreign companies than there are reports and ratings published
about U.S.  companies  and  the  U.S.  government.  In  addition,  where  public
information  is  available,  it  may  be  less  reliable  than  such information
regarding U.S.  issuers.  Issuers of  securities  on foreign  jurisdictions  are
generally  not subject to the same degree of regulation as are U.S. issuers with
respect to such matters as restrictions on market manipulation, insider  trading
rules,  shareholder proxy requirements and  timely disclosure of information. In
addition,  for  companies  that  keep  accounting  records  in  local  currency,
inflation  accounting rules in  some Latin American  countries require, for both
tax and accounting purposes, that certain assets and liabilities be restated  on
the  company's balance sheet in  order to express items  in terms of currency of
constant purchasing power. Inflation  accounting may indirectly generate  losses
or profits.
    
 
   
    CURRENCY  FLUCTUATIONS. Because the Funds,  under normal circumstances, each
will invest  a substantial  portion of  its total  assets in  the securities  of
foreign  issuers which  are denominated in  foreign currencies,  the strength or
weakness of the  U.S. dollar against  such foreign currencies  will account  for
part  of  each Fund's  investment performance.  A  decline in  the value  of any
particular currency against  the U.S. dollar  will cause a  decline in the  U.S.
dollar  value of a  Fund's holdings of  securities and cash  denominated in such
currency and, therefore, will cause an  overall decline in the Fund's net  asset
value  and  any  net  investment  income and  capital  gains  derived  from such
securities to  be distributed  in U.S.  dollars to  shareholders of  that  Fund.
Moreover,  if the value of  the foreign currencies in  which a Fund receives its
income falls relative to the U.S. dollar  between receipt of the income and  the
making  of Fund distributions, the Fund  may be required to liquidate securities
in order to make distributions if the Fund has insufficient cash in U.S. dollars
to meet distribution requirements.
    
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors including  the supply and  demand for particular currencies,
central bank efforts to support particular currencies, the movement of  interest
rates,  the pace of business activity in  certain other countries and the United
States, and other economic and financial conditions affecting the world economy.

                         AIM LATIN AMERICAN GROWTH FUND
 
   
Although the Funds value their  assets daily in terms  of U.S. dollars, they  do
not  intend to convert their holdings of foreign currencies into U.S. dollars on
a daily basis. The Funds will do so  from time to time, and investors should  be
aware  of the costs of currency conversion. Although foreign exchange dealers do
not charge  a  fee  for conversion,  they  do  realize a  profit  based  on  the
difference  ("spread") between the  prices at which they  are buying and selling
various currencies. Thus, a  dealer may offer  to sell a  foreign currency to  a
Fund  at one rate, while offering a lesser rate of exchange should a Fund desire
to sell that currency to the dealer.
    
 
   
Certain  Latin  American  countries  may  have  managed  currencies  which   are
maintained  at  artificial  levels to  the  U.S.  dollar rather  than  at levels
determined by the  market. This  type of  system can  lead to  sudden and  large
adjustments  in the currency which, in turn,  can have a disruptive and negative
effect on foreign investors. For example, in late 1994 the value of the  Mexican
peso lost more than one-third of its value relative to the dollar. Certain Latin
American  countries also may restrict the free conversion of their currency into
foreign currencies, including the U.S.  dollar. There is no significant  foreign
exchange  market for certain currencies and it  would, as a result, be difficult
for the Funds to engage in foreign currency transactions designed to protect the
value of the Funds' interests in securities denominated in such currencies.
    
 
   
    ADVERSE MARKET CHARACTERISTICS.  Securities of many  foreign issuers may  be
less  liquid and their  prices more volatile than  securities of comparable U.S.
issuers. In  addition,  foreign securities  markets  and brokers  generally  are
subject  to  less governmental  supervision and  regulation  than in  the United
States  and  foreign  securities  transactions  usually  are  subject  to  fixed
commissions,  which  generally are  higher than  negotiated commissions  on U.S.
transactions. In addition,  foreign securities  transactions may  be subject  to
difficulties  associated  with the  settlement of  such transactions.  Delays in
settlement could  result in  temporary  periods when  assets  of the  Funds  are
uninvested  and no  return is earned  thereon. The  inability of a  Fund to make
intended security purchases due to settlement  problems could cause the Fund  to
miss  attractive opportunities. Inability to dispose of a portfolio security due
to settlement problems either could result in losses to a Fund due to subsequent
declines in value of the portfolio security  or, if the Fund has entered into  a
contract  to  sell  the security,  could  result  in possible  liability  to the
purchaser. The Sub-adviser will consider such difficulties when determining  the
allocation  of the Funds' assets, although the Sub-adviser does not believe that
such difficulties will have  a material adverse effect  on the Funds'  portfolio
trading activities.
    
 
   
Each  Fund may use  foreign custodians, which  may involve risks  in addition to
those related to the  use of U.S. custodians.  Such risks include  uncertainties
relating  to (i) determining  and monitoring the  financial strength, reputation
and standing of the foreign  custodian, (ii) maintaining appropriate  safeguards
to protect a Fund's investments and (iii) possible difficulties in obtaining and
enforcing judgments against such custodians.
    
 
   
A  high proportion of the shares of many Latin American companies may be held by
a limited  number of  persons, which  may  further limit  the number  of  shares
available  for  investment by  the Funds,  particularly  Latin American  Fund. A
limited number of issuers in most, if not all, Latin American securities markets
may represent a disproportionately large percentage of market capitalization and
trading value. The limited liquidity  of Latin American securities markets  also
may affect a Fund's ability to acquire or dispose of securities at the price and
time it wishes to do so. In addition, certain Latin American securities markets,
including those of Argentina, Brazil, Chile and Mexico, are susceptible to being
influenced  by large  investors trading significant  blocks of  securities or by
large dispositions of securities resulting from the failure to meet margin calls
when due.
    
 
   
The high volatility of certain Latin American securities markets is evidenced by
dramatic movements in the  Brazilian and Mexican markets  in recent years.  This
market  volatility may result in greater volatility  in a Fund's net asset value
than would be the case for companies investing in domestic securities. If a Fund
were to  experience unexpected  net  redemptions, it  could  be forced  to  sell
securities  in  its  portfolio  without  regard  to  investment  merit,  thereby
decreasing the asset base  over which Fund expenses  can be spread and  possibly
reducing the Fund's rate of return.
    
 
   
    WITHHOLDING  TAXES.  Each Fund's  net investment  income from  securities of
foreign issuers may  be subject  to withholding  taxes by  the foreign  issuer's
country,  thereby reducing that  income or delaying the  receipt of income where
those taxes may be recaptured. See "Taxes."
    
 
   
    CONCENTRATION. To the  extent a Fund  invests a significant  portion of  its
assets in securities of issuers located in a particular country or region of the
world,  it may be subject to greater risks and may experience greater volatility
than a fund that is more broadly diversified geographically.
    
 
    SPECIAL CONSIDERATIONS  AFFECTING  EMERGING  MARKETS.  Investing  in  equity
securities  of  companies  in emerging  markets  may entail  greater  risks than
investing in equity securities in  developed countries. These risks include  (i)
less social, political

                         AIM LATIN AMERICAN GROWTH FUND
   
and  economic stability;  (ii) the  small current size  of the  markets for such
securities and the currently low or nonexistent volume of trading, which  result
in  a lack of liquidity and in  greater price volatility; (iii) certain national
policies  which  may  restrict  a  Fund's  investment  opportunities,  including
restrictions on investment in issuers or industries deemed sensitive to national
interests;  (iv) foreign taxation;  and (v) the  absence of developed structures
governing private or  foreign investment  or allowing for  judicial redress  for
injury to private property.
    
 
   
Investing  in the  securities of  companies in  emerging markets,  including the
markets of Latin America and certain Asian markets such as Taiwan, Malaysia  and
Indonesia, may entail special risks relating to potential political and economic
instability and the risks of expropriation, nationalization, confiscation or the
imposition  of  restrictions  on foreign  investment,  convertibility  into U.S.
dollars  and  on  repatriation  of  capital  invested.  In  the  event  of  such
expropriation,  nationalization  or other  confiscation by  any country,  a Fund
could lose its entire investment in any such country.
    
 
   
Emerging  securities  markets  such  as   the  markets  of  Latin  America   are
substantially  smaller, less developed,  less liquid and  more volatile than the
major securities markets. The  limited size of  emerging securities markets  and
limited  trading value  in issuers  compared to  the volume  of trading  in U.S.
securities could cause prices to be erratic for reasons apart from factors  that
affect the quality of the securities. For example, limited market size may cause
prices  to be unduly influenced by  traders who control large positions. Adverse
publicity and  investors'  perceptions,  whether or  not  based  on  fundamental
analysis,  may  decrease  the  value  and  liquidity  of  portfolio  securities,
especially in these markets. In addition, securities traded in certain  emerging
markets   may  be  subject  to  risks  due  to  the  inexperience  of  financial
intermediaries, a lack of  modern technology, the lack  of a sufficient  capital
base  to  expand  business  operations,  and  the  possibility  of  permanent or
temporary termination of trading.
    
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in more developed markets.  In such emerging securities there may
be share registration and delivery delays or failures.
 
   
Many emerging  market  countries  including  countries  in  Latin  America  have
experienced  substantial, and in some periods extremely high, rates of inflation
for many years. This has, in turn lead to high interest rates, extreme  measures
by governments to keep inflation in check and a generally debilitating effect on
economic  growth.  Inflation  and  rapid  fluctuations  in  inflation  rates and
corresponding currency devaluations have had  and may continue to have  negative
effects  on  the economies  and securities  markets  of certain  emerging market
countries including countries in Latin America.
    
 
   
    SPECIAL CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN  COUNTRIES.
Investing  in Russia  and Eastern European  countries involves a  high degree of
risk and special considerations not  typically associated with investing in  the
U.S.  securities markets and should be considered highly speculative. Such risks
include the following: (1) delays in settling portfolio transactions and risk of
loss arising out of the system of  share registration and custody; (2) the  risk
that  it may be impossible  or more difficult than  in other countries to obtain
and/or enforce a  judgement; (3) pervasiveness  of corruption and  crime in  the
economic system; (4) currency exchange rate volatility and the lack of available
currency  hedging instruments; (5) higher rates of inflation (including the risk
of  social  unrest  associated  with   periods  of  hyper-inflation)  and   high
unemployment; (6) controls on foreign investment and local practices disfavoring
foreign  investors and limitations on  repatriation of invested capital, profits
and dividends,  and on  the  ability of  Developing  Markets Fund  and  Emerging
Markets  Fund  to  exchange local  currencies  for U.S.  dollars;  (7) political
instability and social unrest and violence; (8) the risk that the governments of
Russia and Eastern European countries may decide not to continue to support  the
economic  reform  programs  implemented  recently  and  could  follow  radically
different political  and/or economic  policies to  the detriment  of  investors,
including non-market-oriented policies such as the support of certain industries
at  the expense  of other  sectors or  investors, or  a return  to the centrally
planned economy  that  existed when  such  countries  had a  communist  form  of
government;  (9)  the  financial  condition  of  companies  in  these countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of international trade;  (11) the risk  that the tax  system in these  countries
will  not  be reformed  to prevent  inconsistent, retroactive  and/or exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
    
 
    SPECIAL CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of  the
risks  associated with international investments  are heightened for investments
in Pacific region  countries. For  example, some  of the  currencies of  Pacific
region  countries  have experienced  steady  devaluations relative  to  the U.S.
dollar, and major  adjustments have been  made periodically in  certain of  such
currencies. Certain countries, such as India, face serious exchange constraints.

Many  of the Asia Pacific region countries may be subject to a greater degree of
social, political  and economic  instability  than is  the  case in  the  United
States. Such instability may result from, among other things, the following: (i)
authoritarian  governments  or military  involvement  in political  and economic
decision making, and changes  in government through extra-constitutional  means;
(ii) popular unrest associated with demands for improved political, economic and
social  conditions;  (iii) internal  insurgencies;  (iv) hostile  relations with
neighboring countries; and (v) ethnic,  religious and racial disaffection.  Such
social,  political  and  economic instability  could  significantly  disrupt the
principal financial  markets  in  which Developing  Markets  Fund  and  Emerging
Markets  Fund invest and  adversely affect the  value of such  Funds' assets. In
addition,  asset  expropriations  or  future  confiscatory  levels  of  taxation
possibly may affect the Funds.
    
 
Several  of the  Asia Pacific region  countries have,  or in the  past have had,
hostile relationships  with neighboring  nations  or have  experienced  internal
insurgency.  Thailand has experienced  border conflicts with  Laos and Cambodia,
and India is engaged in border disputes with several of its neighbors, including
China and Pakistan. An uneasy truce exists between North Korea and South  Korea,
and the recurrence of hostilities remains possible. Reunification of North Korea
and  South Korea could have a detrimental  effect on the economy of South Korea.
Also, China  continues  to  claim  sovereignty  over  Taiwan  and  recently  has
conducted military maneuvers near Taiwan.
 
The economies of most of the Asia Pacific region countries are heavily dependent
upon  international  trade  and  are accordingly  affected  by  protective trade
barriers and the economic conditions of their trading partners, principally  the
United  States, Japan,  China and the  European Community. The  enactment by the
United States  or  other  principal  trading  partners  of  protectionist  trade
legislation,  reduction of foreign investment in the local economies and general
declines in  the  international  securities markets  could  have  a  significant
adverse effect upon the securities markets of the Asia Pacific region countries.
In  addition,  the  economies of  some  of  the Asia  Pacific  region countries,
Australia and Indonesia, for example, are vulnerable to weakness in world prices
for their commodity exports, including crude oil.
 
China recently assumed sovereignty over Hong  Kong in July 1997. Although  China
has  committed by treaty to preserve the economic and social freedoms enjoyed in
Hong Kong for fifty years, the continuation of the current form of the  economic
system  in Hong Kong will  depend on the actions of  the government of China. In
addition, such assumption of sovereignty has increased sensitivity in Hong  Kong
to  political developments and  statements by public  figures in China. Business
confidence in  Hong  Kong, therefore,  can  be significantly  affected  by  such
developments  and  statements, which  in turn  can  affect markets  and business
performance.
 
In addition, the Chinese  sovereignty over Hong Kong  also presents a risk  that
the  Hong Kong dollar will  be devalued and a risk  of possible loss of investor
confidence in the Hong Kong markets and dollar. However, factors exist that  are
likely to mitigate this risk. First, China has stated its intention to implement
a  "one country, two systems" policy,  which would preserve monetary sovereignty
and leave control in the hands of the Hong Kong Monetary Authority ("HKMA").
 
Second, fixed  rate  parity  with  the  U.S.  dollar  is  seen  as  critical  to
maintaining  investors'  confidence  in  the transition  to  Chinese  rule, and,
therefore, it is anticipated that, if international investors lose confidence in
Hong Kong  dollar assets,  the HKMA  would intervene  to support  the  currency,
though  such  intervention cannot  be assured.  Third,  Hong Kong's  and China's
sizable combined foreign exchange  reserve may be used  to support the value  of
the Hong Kong dollar, provided that China does not appropriate such reserves for
other uses, which is not anticipated but cannot be assured. Finally, China would
be  likely to experience significant adverse political and economic consequences
if confidence  in the  Hong Kong  dollar and  the territory  assets were  to  be
endangered.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.

                         AIM LATIN AMERICAN GROWTH FUND
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
   
It should  be noted  that  some Latin  American countries  require  governmental
approval  for the repatriation of investment  income, capital or the proceeds of
securities sales  by  foreign  investors.  For  instance,  at  present,  capital
invested directly in Chile cannot under most circumstances be repatriated for at
least  one year. The Funds, particularly Latin American Fund, could be adversely
affected by delays in, or a refusal to grant, any required governmental approval
for repatriation, as well as by the  application to it of other restrictions  on
investments.
    
 
    SOVEREIGN  DEBT. Sovereign Debt generally offers high yields, reflecting not
only perceived  credit risk,  but also  the  need to  compete with  other  local
investments  in domestic financial markets. Certain Latin American countries are
among the  largest  debtors  to  commercial banks  and  foreign  governments.  A
sovereign debtor's willingness or ability to repay principal and interest due in
a  timely  manner  may  be  affected by,  among  other  factors,  its  cash flow
situation, the extent of  its foreign reserves,  the availability of  sufficient
foreign  exchange on the  date a payment is  due, the relative  size of the debt
service burden to the economy as a whole, the sovereign debtor's policy  towards
the  International  Monetary  Fund  and the  political  constraints  to  which a
sovereign debtor  may  be  subject.  Sovereign  debtors  may  default  on  their
Sovereign   Debt.  Sovereign   debtors  may   also  be   dependent  on  expected
disbursements from foreign governments, multilateral agencies and others  abroad
to reduce principal and interest arrearages on their debt. The commitment on the
part of these governments, agencies and others to make such disbursements may be
conditioned  on a sovereign  debtor's implementation of  economic reforms and/or
economic performance  and  the  timely service  of  such  debtor's  obligations.
Failure  to implement such reforms, achieve  such levels of economic performance
or repay principal or interest when due, may result in the cancellation of  such
third  parties' commitments  to lend  funds to  the sovereign  debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
 
   
In recent years, some of the Latin American countries in which the Funds  expect
to  invest have encountered difficulties in servicing their Sovereign Debt. Some
of these  countries  have withheld  payments  of interest  and/or  principal  of
Sovereign  Debt. These difficulties  have also led  to agreements to restructure
external debt obligations -- in particular, commercial bank loans, typically  by
rescheduling  principal  payments,  reducing interest  rates  and  extending new
credits to finance interest payments on existing debt. In the future, holders of
Sovereign Debt may be requested to participate in similar reschedulings of  such
debt.
    
 
   
The  ability  of Latin  American governments  to make  timely payments  on their
Sovereign Debt is  likely to be  influenced strongly by  a country's balance  of
trade  and its access to trade and  other international credits. A country whose
exports are concentrated in a few  commodities could be vulnerable to a  decline
in  the  international prices  of  one or  more  of such  commodities. Increased
protectionism on the part of a  country's trading partners could also  adversely
affect  its  exports.  Such  events could  diminish  a  country's  trade account
surplus, if any. To the extent that  a country receives payment for its  exports
in  currencies other  than hard  currencies, its  ability to  make hard currency
payments could be affected.
    
 
   
The occurrence of political, social or diplomatic changes in one or more of  the
countries  issuing Sovereign Debt  could adversely affect  a Fund's investments.
The countries  issuing such  instruments  are faced  with social  and  political
issues and some of them have experienced high rates of inflation in recent years
and  have  extensive  internal debt.  Among  other effects,  high  inflation and
internal  debt  service   requirements  may  adversely   affect  the  cost   and
availability  of  future domestic  sovereign  borrowing to  finance governmental
programs,  and  may   have  other   adverse  social,   political  and   economic
consequences.  Political  changes or  a  deterioration of  a  country's domestic
economy or balance of trade may  affect the willingness of countries to  service
their  Sovereign  Debt.  While the  Sub-adviser  intends to  manage  each Fund's
portfolio in a manner that will minimize  the exposure to such risks, there  can
be  no assurance  that adverse  political changes  will not  cause the  Funds to
suffer losses of interest or principal on any of their holdings.
    
 
   
Periods of economic uncertainty may result in the volatility of market prices of
Sovereign Debt and in turn, a Fund's  net asset value, to a greater extent  than
the volatility inherent in domestic securities. The value of Sovereign Debt will
likely  vary  inversely with  changes in  prevailing  interest rates,  which are
subject to considerable variance in the international market. If a Fund were  to
experience  unexpected net redemptions, it may  be forced to sell Sovereign Debt
in its  portfolio without  regard to  investment merit,  thereby decreasing  its
asset base over which Fund expenses can be spread and possibly reducing its rate
of return.

securities.
    
 
   
Developing Markets Fund may not:
    
 
   
        (1)  issue senior securities or borrow  money, except as permitted under
    the 1940 Act and then not in excess of 33 1/3% of Developing Markets  Fund's

    the amount borrowed) for temporary or emergency purposes;
    
 
   
        (2) purchase any security if, as a result of that purchase, 25% or  more
    of Developing Markets Fund's total assets would be invested in securities of
    issuers  having their  principal business  activities in  the same industry,
    except  that  this  limitation  does  not  apply  to  securities  issued  or
    guaranteed by the U.S. government, its agencies or instrumentalities;
    
 
   
        (3)  engage in the business of underwriting securities of other issuers,
    except to the  extent that Developing  Markets Fund might  be considered  an
    underwriter  under  the  federal  securities  laws  in  connection  with its
    disposition of portfolio securities;
    
 
   
        (4) purchase or sell real estate, except that investments in  securities

    interests in real estate are not subject to this limitation, and except that
    Developing  Markets Fund  may exercise  rights under  agreements relating to
    such securities, including the  right to enforce  security interests and  to
    hold  real estate  acquired by  reason of  such enforcement  until that real
    estate can be liquidated in an orderly manner;
    
 
   
        (5) purchase or sell physical  commodities, but Developing Markets  Fund
    may  purchase, sell or enter into financial options and futures, forward and
    spot currency contracts, swap transactions and other financial contracts  or
    derivative instruments; or
    
 
        (6)  make loans, except through loans of portfolio securities or through
    repurchase agreements, provided  that for purposes  of this limitation,  the
    acquisition  of bonds, debentures, other  debt securities or instruments, or
    participations or  other interests  therein  and investments  in  government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan.
 
   
Notwithstanding  any other investment policy, Developing Markets Fund may invest
all of  its  investable assets  (cash,  securities and  receivables  related  to
securities)  in an  open-end management investment  company having substantially

For purposes of the concentration policy of Developing Markets Fund contained in
limitation (2) above,  the Fund intends  to comply with  the SEC staff  position
that  securities issued or  guaranteed as to  principal and interest  by any one
single  foreign  government,  or  by  all  supranational  organizations  in  the
aggregate, are considered to be securities of issuers in the same industry.
    
 
   
In  addition, to  comply with  federal tax  requirements for  qualification as a
"regulated investment company"  ("RIC"), Developing  Markets Fund's  investments
will  be limited so that, at the close  of each quarter of its taxable year, (a)
not more than 25% of the value of its total assets is invested in the securities
(other than U.S government  securities or the securities  of other RICs) of  any
one  issuer and (b) at least 50% of the value of its total assets is represented
by cash and cash items, U.S. government securities, securities of other RICs and
other securities, with  these other securities  limited, in respect  of any  one
issuer,  to an amount that does  not exceed 5% of the  value of its total assets
and that does  not represent more  than 10% of  the issuer's outstanding  voting
securities  ("Diversification Requirements"). These  tax-related limitations may
be changed by the Trust's  Board of Trustees to  the extent necessary to  comply
with changes to applicable tax requirements.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject  to  policies  established  by  the  Trust's  Board  of  Trustees,   the
Sub-adviser   is  responsible  for  the   execution  of  each  Fund's  portfolio
transactions and the selection of  broker/dealers who execute such  transactions
on  behalf of  the Funds. In  executing portfolio  transactions, the Sub-adviser
seeks the best net results  for each Fund, taking  into account such factors  as
the price (including the applicable brokerage commission or dealer spread), size
of  the order,  difficulty of execution  and operational facilities  of the firm
involved.  Although  the  Sub-adviser  generally  seeks  reasonably  competitive
commission  rates and spreads, payment of the lowest commission or spread is not
necessarily consistent with the best net results. While the Funds may engage  in
soft  dollar arrangements for  research services, as  described below, the Funds
have no obligation to deal with any broker/dealer or group of broker/dealers  in
the execution of portfolio transactions.
    
 
Debt  securities generally are traded  on a "net" basis  with a dealer acting as
principal for its own account without a stated commission, although the price of
the security  usually  includes  a  profit  to  the  dealer.  U.S.  and  foreign
government  securities and money market instruments  generally are traded in the
OTC markets. In underwritten  offerings, securities usually  are purchased at  a
fixed  price which  includes an  amount of  compensation to  the underwriter. On
occasion, securities may be purchased directly from an issuer, in which case  no
commissions  or discounts  are paid.  Broker/dealers may  receive commissions on
futures, currency and options transactions.
 
   
Consistent with the interests of each  Fund, the Sub-adviser may select  brokers
to  execute a Fund's  portfolio transactions, on  the basis of  the research and
brokerage services they provide to the  Sub-adviser for its use in managing  the
Fund  and  its other  advisory accounts.  Such  services may  include furnishing
analyses, reports and  information concerning  issuers, industries,  securities,
geographic  regions,  economic  factors  and  trends,  portfolio  strategy,  and
performance of accounts;  and effecting securities  transactions and  performing
functions  incidental thereto (such  as clearance and  settlement). Research and
brokerage services received  from such brokers  are in addition  to, and not  in
lieu  of, the  services required  to be performed  by the  Sub-adviser under the
investment management and  administration contracts. A  commission paid to  such
brokers  may  be higher  than  that which  another  qualified broker  would have
charged for  effecting  the  same transaction,  provided  that  the  Sub-adviser
determines  in good faith that such commission  is reasonable in terms either of
that particular transaction or the overall responsibility of the Sub-adviser  to
a  Fund and its  other clients and that  the total commissions  paid by the Fund
will be reasonable in relation to the  benefits it received over the long  term.
Research   services  may  also  be  received   from  dealers  who  execute  Fund
transactions in OTC markets.
    
 
   
The Sub-adviser may allocate brokerage  transactions to broker/dealers who  have
entered  into arrangements under which the  broker/dealer allocates a portion of
the commissions paid by a  Fund toward payment of  the Fund's expenses, such  as
transfer agent and custodian fees.
    
 
   
Investment  decisions for each Fund and for other investment accounts managed by
the Sub-adviser  are made  independently of  each other  in light  of  differing
conditions.  However, the same investment decision  occasionally may be made for
two or more of  such accounts including the  Funds. In such cases,  simultaneous
transactions  may occur. Purchases  or sales are  then allocated as  to price or
amount in a manner deemed fair and equitable to all accounts involved. While  in
some cases this practice could have a detrimental effect upon the price or value
of  the security as far as a Fund  is concerned, in other cases, the Sub-adviser
believes that coordination and the ability to participate in volume transactions
will be beneficial to that Fund.
    
 
   
Under a policy  adopted by the  Trust's Board  of Trustees, and  subject to  the
policy  of  obtaining  the best  net  results,  the Sub-adviser  may  consider a
broker/dealer's sale of the shares of a  Fund and the other funds for which  AIM
or the Sub-adviser serves as investment manager in selecting brokers and dealers
for  the  execution of  portfolio  transactions. This  policy  does not  imply a
commitment to  execute portfolio  transactions through  all broker/dealers  that
sell shares of the Funds and such other funds.
    
 
   
Each   Fund   contemplates  purchasing   most   foreign  equity   securities  in
over-the-counter markets or stock  exchanges located in  the countries in  which
the  respective principal offices  of the issuers of  the various securities are
located, if that is the best

available market.  The  fixed commissions  paid  in connection  with  most  such
foreign  stock transactions generally are  higher than negotiated commissions on
U.S. transactions. There generally is less government supervision and regulation
of foreign  stock exchanges  and  brokers than  in  the United  States.  Foreign
security  settlements may  in some  instances be  subject to  delays and related
administrative uncertainties.
 
   
Foreign equity securities may be  held by each Fund in  the form of ADRs,  ADSs,
EDRs, GDRs, CDRs or securities convertible into foreign equity securities. ADRs,
ADSs, EDRs, GDRs and CDRs may be listed on stock exchanges, or traded in the OTC
markets  in the United  States or Europe, as  the case may  be. ADRs, like other
securities traded in the United States, will be subject to negotiated commission
rates. The foreign and domestic debt securities and money market instruments  in
which a Fund may invest generally are traded in the OTC markets.
    
 
   
Each  Fund contemplates that,  consistent with the policy  of obtaining the best
net results, brokerage transactions may  be conducted through certain  companies
affiliated  with AIM or Sub-adviser. The  Trust's Board of Directors has adopted
procedures in conformity with Rule 17e-1 under  the 1940 Act to ensure that  all
brokerage  commissions paid  to such affiliates  are reasonable and  fair in the
context of the market in which they are operating. Any such transactions will be
effected and related compensation  paid only in  accordance with applicable  SEC
regulations.
    
 
   
For  the fiscal years  ended December 31,  1997, 1996 and  1995, the Predecessor
Fund  paid  aggregate  brokerage  commissions  of  $2,212,022,  $1,580,879   and
$1,311,090,  respectively. For the fiscal years ended October 31, 1997, 1996 and
1995, Emerging Markets Fund paid aggregate brokerage commissions of  $3,274,528,
$3,648,347  and $3,307,402, respectively. For the fiscal years ended October 31,
1997, 1996 and 1995, Latin American Fund paid aggregate brokerage commissions of
$2,719,660, $2,094,634 and $891,513, respectively.
    
 
PORTFOLIO TRADING AND TURNOVER
   
Each Fund engages in portfolio trading  when the Sub-adviser has concluded  that
the sale of a security owned by the Fund and/or the purchase of another security
of  better value can enhance principal and/or increase income. A security may be
sold to avoid  any prospective decline  in market  value, or a  security may  be
purchased  in  anticipation  of  a  market  rise.  Consistent  with  each Fund's
investment objective, a  security also  may be  sold and  a comparable  security
purchased  coincidentally in order to take advantage of what is believed to be a
disparity in the normal yield and price relationship between the two securities.
Although none of the  Funds generally intends to  trade for short-term  profits,
the  securities in a Fund's portfolio  will be sold whenever management believes
it is appropriate to do  so, without regard to the  length of time a  particular
security  may have been held. Portfolio  turnover rate is calculated by dividing
the lesser of  sales or purchases  of portfolio securities  by a Fund's  average
month-end  portfolio  values,  excluding short-term  investments.  The portfolio
turnover rate will not be a limiting factor when the Sub-adviser deems portfolio
changes appropriate. Higher portfolio turnover involves correspondingly  greater
brokerage commissions and other transaction costs that a Fund will bear directly
and  may result in  the realization of  net capital gains  that are taxable when
distributed to that Fund's shareholders. For the fiscal years ended December 31,
1997 and 1996,  the Predecessor Fund's  portfolio turnover rates  were 184%  and
138%,  respectively.  For the  fiscal  years ended  October  31, 1997  and 1996,
Emerging  Markets  Fund's   portfolio  turnover  rates   were  150%  and   104%,
respectively.  Latin  American Fund's  portfolio turnover  rates for  the fiscal
years ended October 31, 1997 and 1996 were 130% and 101%, respectively.

The Board of Trustees  has a Nominating and  Audit Committee, comprised of  Miss
Quigley  and Messrs.  Anderson, Bayley and  Patterson, which  is responsible for
nominating persons to serve as Trustees,  reviewing audits of the Trust and  its
funds  and recommending  firms to serve  as independent auditors  for the Trust.
Each of the Trustees and Officers of the Trust is also a Director or Trustee and
Officer of AIM Investment Portfolios, AIM Floating Rate Fund, AIM Growth Series,
AIM Series Trust, AIM Eastern Europe Fund, GT Global Variable Investment  Trust,
GT  Global  Variable Investment  Series,  Global High  Income  Portfolio, Growth
Portfolio, Floating Rate  Portfolio and Global  Investment Portfolio, which  are
also  registered  investment companies  advised by  AIM  and sub-advised  by the
Sub-adviser or an affiliate thereof. All  of the Trust's Trustees also serve  as
directors  or trustees of some or all of the other investment companies managed,
administered or  advised by  AIM. All  of the  Trust's executive  officers  hold
similar  offices with  some or  all of  the other  investment companies managed,
administered or advised by AIM. Each Trustee  who is not a director, officer  or
employee  of the Sub-adviser or any affiliated company is paid aggregate fees of
$5,000 a year plus  $300 per Fund  for each meeting of  the Board attended,  and
reimbursed  travel and other expenses incurred  in connection with attendance at
such meetings. Other Trustees  and Officers receive  no compensation or  expense
reimbursement  from the Trust. For  the fiscal year ended  October 31, 1997, Mr.
Anderson, Mr. Bayley,  Mr. Patterson and  Miss Quigley, who  are not  directors,
officers  or employees  of the Sub-adviser  or any  affiliated company, received
total compensation of $38,650, $38,650, $27,850 and $38,650, respectively,  from
the  Trust for their services as Trustees. For the fiscal year ended October 31,
1997, Mr. Anderson,  Mr. Bayley,  Mr. Patterson and  Miss Quigley,  who are  not
directors,  officers or  employees of  the Sub-adviser  or any  other affiliated
company,  received  total  compensation  of  $117,304,  $114,386,  $88,350   and
$111,688, respectively, from the investment companies managed or administered by
AIM  and sub-advised or sub-administered by the  Sub-adviser for which he or she
serves as a  Director or Trustee.  Fees and expenses  disbursed to the  Trustees
contained  no accrued or payable pension or  retirement benefits. As of June 26,

- --------------------------------------------------------------------------------
 
   
                             THE DISTRIBUTION PLANS
    
 
   
THE  CLASS A PLAN. The Trust has  adopted a Master Distribution Plan pursuant to
Rule 12b-1 under the 1940 Act relating to  the Class A shares of the Funds  (the
"Class A Plan"). The Class A Plan provides that the Class A shares pay 0.50% per
annum  of their average daily net assets as compensation to AIM Distributors for
the purpose of financing any activity  which is primarily intended to result  in
the  sale of Class  A shares. Of such  amounts, each Fund pays  a service fee of
0.25% of the average daily net assets attributable to Class A shares to selected
dealers and  other institutions  which furnish  continuing personal  shareholder
services  to their  customers who  purchase and  own Class  A shares. Activities
appropriate for financing under  the Class A Plan  include, but are not  limited
to,  the  following:  printing  of  prospectuses  and  statements  of additional
information  and  reports  for  other  than  existing  shareholders;   overhead;
preparation  and  distribution  of advertising  material  and  sales literature;
expenses of organizing and conducting  sales seminars; supplemental payments  to
dealers  and other institutions such as asset-based sales charges or as payments
of  service  fees   under  shareholder  service   arrangements;  and  costs   of
administering the Class A Plan.
    
 
   
THE CLASS B PLAN. The Trust has also adopted a Master Distribution Plan pursuant
to  Rule 12b-1 under the 1940  Act relating to Class B  shares of the Funds (the
"Class B Plan", and collectively with the Class A Plan, the "Plans"). Under  the
Class  B Plan, each Fund pays compensation to AIM Distributors at an annual rate
of 1.00% of the average daily net assets attributable to Class B shares. Of such
amount, each Fund pays a  service fee of 0.25% of  the average daily net  assets
attributable  to Class B shares to selected dealers and other institutions which
furnish continuing personal shareholder services to their customers who purchase
and own Class B shares. Amounts paid in accordance with the Class B Plan may  be
used to finance any activity primarily intended to result in the sale of Class B
shares,  including but not limited to printing of prospectuses and statements of
additional  information  and  reports  for  other  than  existing  shareholders;
overhead;  preparation  and  distribution  of  advertising  material  and  sales
literature; expenses of organizing  and conducting sales seminars;  supplemental
payments  to dealers and other institutions such as asset-based sales charges or
as payments of service fees under shareholder service arrangements; and costs of
administering the  Class B  Plan. AIM  Distributors may  transfer and  sell  its
rights  to payments  under the  Class B  Plan in  order to  finance distribution
expenditures in respect of Class B shares.
    
 
   
BOTH PLANS. Pursuant to  an incentive program, AIM  Distributors may enter  into
agreements  ("Shareholder Service Agreements")  with investment dealers selected
from time  to  time  by  AIM Distributors  for  the  provision  of  distribution
assistance  in connection with  the sale of  the Funds' shares  to such dealers'
customers, and for the provision of continuing personal shareholder services  to
customers  who may from time to time  directly or beneficially own shares of the
Funds. The distribution assistance and continuing personal shareholder  services
to  be rendered by dealers under the Shareholder Service Agreements may include,
but shall  not be  limited  to, the  following: distributing  sales  literature;
answering  routine customer inquiries concerning  the Funds; assisting customers
in changing  dividend  options,  account  designations  and  addresses,  and  in
enrolling  in any of the several  special investment plans offered in connection
with the  purchase of  the Funds'  shares; assisting  in the  establishment  and
maintenance  of customer accounts and records  and in the processing of purchase
and  redemption  transactions;  investing   dividends  and  any  capital   gains
distributions  automatically  in the  Funds'  shares; and  providing  such other
information and services as the Funds or the customer may reasonably request.
    
 
   
Under the Plans, in addition  to the Shareholder Service Agreements  authorizing
payments   to  selected  dealers,  banks  may  enter  into  Shareholder  Service
Agreements authorizing  payments under  the  Plans to  be  made to  banks  which
provide services to their customers who have purchased shares. Services provided
pursuant to Shareholder Service Agreements with banks may include some or all of
the  following: answering shareholder inquiries  regarding the Funds; performing
sub-accounting; establishing and maintaining  shareholder accounts and  records;
processing  customer  purchase and  redemption transactions;  providing periodic
statements showing a shareholder's account  balance and the integration of  such
statements  with those of  other transactions and  balances in the shareholder's
other accounts serviced by the  bank; forwarding applicable prospectuses,  proxy
statements,  reports and notices to bank clients  who hold Fund shares; and such

other administrative services as the Funds reasonably may request, to the extent
permitted by applicable statute, rule  or regulation. Similar agreements may  be
permitted  under the Plans for institutions  which provide recordkeeping for and
administrative services to 401(k) plans.
    
 
   
Financial intermediaries and any other  person entitled to receive  compensation
for selling Fund shares may receive different compensation for selling shares of
one particular class over another.
    
 
   
Under a Shareholder Service Agreement, each Fund agrees to pay periodically fees
to  selected dealers and other institutions who render the foregoing services to
their  customers.  The  fees  payable  under  a  Shareholder  Service  Agreement
generally will be calculated at the end of each payment period for each business
day  of the Funds during such period at  the annual rate of 0.25% of the average
daily net  asset  value of  the  Funds'  shares purchased  or  acquired  through
exchange.  Fees calculated in this  manner shall be paid  only to those selected
dealers or other institutions who are  dealers or institutions of record at  the
close  of business on the last business day of the applicable payment period for
the account in which each Fund's shares are held.
    
 
   
Payments pursuant to the Plans are subject to any applicable limitations imposed
by rules of the National Association  of Securities Dealers, Inc. ("NASD").  The
Plans  conform to  rules of the  NASD by  limiting payments made  to dealers and
other  financial  institutions  who  provide  continuing  personal   shareholder
services  to their customers who purchase and own shares of the Funds to no more
than 0.25% per annum of the average  daily net assets of the Funds  attributable
to  the customers of such  dealers or financial institutions,  and by imposing a
cap on the total sales charges, including asset based sales charges, that may be
paid by the Funds and their respective classes.
    
 
   
AIM Distributors does not act as principal,  but rather as agent for the  Funds,
in  making dealer incentive and shareholder  servicing payments under the Plans.
These payments are an obligation of the Funds and not of AIM Distributors.
    
 
   
Prior to  June 1,  1998, the  Trust had  adopted a  different Rule  12b-1,  that
operated  as  a "reimbursement-type"  plan (the  "Prior Plan").  The information
provided below relates to payments made under the Prior Plan, which provided for
payments to GT Global Inc., the distributor  of the Funds at the time the  Prior
Plan was in effect.
    
 
   
For  the  fiscal year  ended December  31,  1997, each  Fund paid  the following
amounts under the Prior Plan:

The Plans require  AIM Distributors to  provide the Board  of Trustees at  least
quarterly  with a written report  of the amounts expended  pursuant to the Plans
and the purposes for  which such expenditures were  made. The Board of  Trustees
reviews  these reports  in connection with  their decisions with  respect to the
Plans.
    
 
   
As required by Rule  12b-1, the Plans and  related forms of Shareholder  Service
Agreements  were approved by the Board of  Trustees, including a majority of the
Trustees who are not "interested  persons" (as defined in  the 1940 Act) of  the
Trust  and who have no direct or indirect financial interest in the operation of
the Plans or in any agreements  related to the Plans ("Qualified Trustees").  In
approving  the  Plans in  accordance with  the requirements  of Rule  12b-1, the
Trustees considered various factors  and determined that  there is a  reasonable
likelihood  that  the Plans  would benefit  each  class of  each Fund  and their
respective shareholders.
    
 
   
The Plans do not obligate the Funds to reimburse AIM Distributors for the actual
expenses AIM  Distributors may  incur in  fulfilling its  obligations under  the
Plans. Thus, even if AIM Distributors' actual expenses exceed the fee payable to
AIM  Distributors thereunder at any given time,  the Funds will not be obligated
to pay more than that fee. If  AIM Distributors' expenses are less than the  fee
it receives, AIM Distributors will retain the full amount of the fee.
    
 
   
Unless  terminated earlier in accordance with their terms, the Plans continue in
effect until  [June  30,  1999]  and  each year  thereafter,  as  long  as  such
continuance is specifically approved at least annually by the Board of Trustees,
including a majority of the Qualified Trustees.
    
 
   
The  Plans  may be  terminated  by the  vote of  a  majority of  the Independent
Trustees, or, with respect to a particular  class, by the vote of a majority  of
the outstanding voting securities of that class.
    
 
   
Any change in the Plans that would increase materially the distribution expenses
paid by the applicable class requires shareholder approval; otherwise, it may be
amended  by the  Trustees, including  a majority  of the  Qualified Trustees, by
votes cast in person  at a meeting  called for the purpose  of voting upon  such
amendment.  As long as the  Plans are in effect,  the selection or nomination of
the Qualified Trustees is committed to the discretion of the Qualified Trustees.
In the event the Class A Plan is amended in a manner which the Board of Trustees
determines would materially increase  the charges paid under  the Class A  Plan,
the  Class B shares of the  Funds will no longer convert  into Class A shares of
the same  Funds unless  the  Class B  shares,  voting separately,  approve  such
amendment.  If the Class B shareholders do not approve such amendment, the Board
of Trustees  will (i)  create  a new  class  of shares  of  the Funds  which  is
identical  in all material respects to the  Class A shares as they existed prior
to the implementation of the amendment and (ii) ensure that the existing Class B
shares of the Funds will be exchanged or converted into such new class of shares
no later than the date the Class B shares were scheduled to convert into Class A
shares.
    
 
   
The principal differences between  the Class A  Plan, on the  one hand, and  the
Class B Plan, on the other hand, are: (i) the Class A Plan allows payment to AIM
Distributors  or to dealers or financial institutions  of up to 0.50% of average
daily net assets of  the Class A shares  of each Fund, as  compared to 1.00%  of
such  assets of each Fund's Class B shares;  (ii) the Class B Plan obligates the
Class B  shares to  continue  to make  payments  to AIM  Distributors  following
termination of the Class B

                                THE DISTRIBUTOR
    
 
   
Information concerning  AIM  Distributors and  the  continuous offering  of  the
Funds' shares is set forth in the Prospectus under the headings "How to Purchase
Shares"  and  "Terms and  Conditions of  Purchase  of the  AIM Funds."  A Master
Distribution Agreement with AIM Distributors relating to the Class A and Class B
shares of the Funds was approved by the Board of Trustees on             , 1998.
Both such Master Distribution  Agreements are hereinafter collectively  referred
to as the "Distribution Agreements."
    
 
   
The Distribution Agreements provide that AIM Distributors will bear the expenses
of  printing from the  final proof and distributing  the Funds' prospectuses and
statements of additional information  relating to public  offerings made by  AIM
Distributors   pursuant  to  the  Distribution   Agreements  (other  than  those
prospectuses and statements  of additional information  distributed to  existing
shareholders  of the Fund), and any promotional  or sales literature used by AIM
Distributors or furnished by AIM Distributors to dealers in connection with  the
public  offering  of the  Fund's shares,  including  expenses of  advertising in
connection with such public  offerings. AIM Distributors  has not undertaken  to
sell any specified number of shares of any classes of the Funds.
    
 
   
AIM  Distributors expects  to pay  sales commissions  from its  own resources to
dealers and institutions who  sell Class B  shares of the Funds  at the time  of
such  sales. Payments  with respect  to Class  B shares  will equal  4.0% of the
purchase price of the Class B shares sold by the dealer or institution, and will
consist of a sales commission equal to 3.75% of the purchase price of the  Class
B  shares sold  plus an  advance of  the first  year service  fee of  0.25% with
respect to such shares.  The portion of the  payments to AIM Distributors  under
the  Class  B Plan  which  constitutes an  asset-based  sales charge  (0.75%) is
intended in part to permit  AIM Distributors to recoup  a portion of such  sales
commissions  plus  financing costs.  AIM Distributors  anticipates that  it will
require a  number of  years  to recoup  from Class  B  Plan payments  the  sales
commissions paid to dealers and institutions in connection with sales of Class B
shares.  In  the  future,  if  multiple distributors  serve  a  Fund,  each such
distributor (or  its  assignee or  transferee)  would  receive a  share  of  the
payments  under the  Class B  Plan based on  the portion  of the  Fund's Class B
shares sold by or attributable to the distribution efforts of that distributor.
    
 
   
The Trust (on behalf of any class of any Fund) or AIM Distributors may terminate
the Distribution Agreements on sixty (60) days' written notice without  penalty.
The  Distribution Agreements will terminate automatically  in the event of their
assignment.  In  the  event  the  Class  B  shares  Distribution  Agreement   is
terminated,  AIM Distributors would continue to  receive payments of asset based
distribution fees in respect of the  outstanding Class B shares attributable  to
the distribution efforts of AIM Distributors; provided, however, that a complete
termination  of the Class B  Plan (as defined in  such Plan) would terminate all
payments to AIM Distributors.  Termination of the Class  B Plan or  Distribution
Agreement  does  not  affect the  obligation  of  the Funds  and  their  Class B
shareholders to pay contingent deferred sales charges.
    
 
   
The following chart reflects the total sales charges paid in connection with the
sale of Class A shares of each Fund and the amount retained by GT Global,  Inc.,
the  Trust's  distributor prior  to  June 1,  1998,  for the  fiscal  year ended
December 31, 1997.

TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The  Transfer Agency  and Service  Agreement between  the Trust  and A  I M Fund
Services, Inc. ("AFS"), a registered transfer agent and wholly-owned  subsidiary
of  AIM, provides  that AFS  will perform  certain shareholder  services for the
Funds for a fee per account serviced. The Transfer Agency and Service  Agreement
provides  that AFS will receive a per account fee plus out-of-pocket expenses to
process orders for purchases, redemptions  and exchanges of shares; prepare  and
transmit  payments  for  dividends  and  distributions  declared  by  the Funds;
maintain  shareholder  accounts  and   provide  shareholders  with   information
regarding  the  Funds  and  their  accounts.  The  Transfer  Agency  and Service
Agreement became effective on September 8, 1998. The Sub-adviser serves as  each
Fund's  pricing and  accounting agent.  For the  fiscal years  ended October 31,
1997, 1996 and 1995, Emerging Markets Fund paid accounting services fees to  the
Sub-adviser  of $103,144,  $125,349 and  $33,216, and  Latin American  Fund paid
accounting services fees of $90,733, $86,436 and $24,138, respectively.
    
 
   
EXPENSES OF THE FUNDS
    
   
Each  Fund  pays  all  expenses  not  assumed  by  AIM,  the  Sub-adviser,   AIM
Distributors  and  other  agents. These  expenses  include, in  addition  to the
advisory, distribution,  transfer  agency,  pricing and  accounting  agency  and
brokerage  fees  discussed  above,  legal and  audit  expenses,  custodian fees,
directors'  fees,  organizational  fees,  fidelity  bond  and  other   insurance
premiums,  taxes,  extraordinary  expenses  and  the  expenses  of  reports  and
prospectuses sent  to  existing  investors.  The  allocation  of  general  Trust
expenses and expenses shared among the Funds and other funds organized as series
of  the Trust are allocated  on a basis deemed fair  and equitable, which may be
based on the  relative net assets  of the Funds  or the nature  of the  services
performed and relative applicability to the Funds. Expenditures, including costs
incurred  in connection with the purchase or sale of portfolio securities, which
are capitalized  in accordance  with  generally accepted  accounting  principles
applicable  to investment companies, are accounted  for as capital items and not
as expenses. The ratio of each Fund's expenses to its relative net assets can be
expected to  be higher  than the  expense ratios  of funds  investing solely  in
domestic  securities,  since  the cost  of  maintaining the  custody  of foreign
securities and  the  rate  of  investment management  fees  paid  by  each  Fund
generally are higher than the comparable expenses of such other funds.

                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
   
The  net asset value per  share of each Fund is  normally determined daily as of
the close of  trading of the  New York Stock  Exchange ("NYSE") (generally  4:00
p.m.  Eastern time)  of each business  day of the  Funds. In the  event the NYSE
closes early (i.e., before 4:00 p.m. Eastern time) on a particular day, the  net
asset value of a Fund is determined as of the close of the NYSE on such day. Net
asset  value  per  share  is  determined  by  dividing  the  value  of  a Fund's
securities, cash and other assets (including interest accrued but not collected)
attributable to a particular class, less all its liabilities (including  accrued
expenses  and dividends payable) attributable to that class, by the total number
of shares outstanding  of that  class. Determination  of each  Fund's net  asset
value  per  share  is  made in  accordance  with  generally  accepted accounting
principles.
    
 
   
Each equity security held  by a Fund is  valued at its last  sales price on  the
exchange  where the security  is principally traded  or, lacking any  sales on a
particular day, the security is valued at  the mean between the closing bid  and
asked  prices on that  day. Each security traded  in the over-the-counter market
(but not including securities reported on the NASDAQ National Market System)  is
valued  at the  mean between  the last  bid and  asked prices  based upon quotes
furnished by market makers  for such securities. Each  security reported on  the
NASDAQ National Market System is valued at the last sales price on the valuation
date or absent a last sales price, at the mean between the closing bid and asked
prices  on that day. Debt securities are  valued on the basis of prices provided
by an independent pricing service. Prices provided by the pricing service may be
determined  without  exclusive  reliance  on  quoted  prices,  and  may  reflect
appropriate  factors  such  as  institution-size trading  in  similar  groups of
securities, developments related to  special securities, yield, quality,  coupon
rate,  maturity,  type of  issue, individual  trading characteristics  and other
market data. Securities for which market quotations are not readily available or
are questionable are  valued at fair  value as  determined in good  faith by  or
under  the  supervision  of  the  Trust's  officers  in  a  manner  specifically
authorized by the Board  of Trustees. Short-term obligations  having 60 days  or
less  to maturity  are valued on  the basis  of amortized cost.  For purposes of
determining net asset value per  share, futures and options contracts  generally
will be valued 15 minutes after the close of trading of the NYSE.
    
 
   
Generally,  trading  in  foreign securities,  corporate  bonds,  U.S. Government
securities and money market instruments  is substantially completed each day  at
various times prior to the close of the NYSE. The values of such securities used
in  computing the net asset  value of each Fund's  shares are determined at such
times. Foreign currency exchange rates  are also generally determined prior  the
close  of the NYSE. Occasionally, events affecting the values of such securities
and such exchange rates  may occur between  the times at  which such values  are
determined  and  the  close of  the  NYSE which  will  not be  reflected  in the
computation of a  Fund's net  asset value.  If events  materially affecting  the
value of such securities occur during such period, then these securities will be
valued  at  their  fair  value as  determined  in  good faith  by  or  under the
supervision of the Board of Trustees.

- --------------------------------------------------------------------------------
   
A complete  description of  the  manner in  which shares  of  the Funds  may  be
purchased appears in the Funds' Prospectuses under the headings "How to Purchase
Shares,"  "Terms  and Conditions  of  Purchase of  the  AIM Funds"  and "Special
Plans."
    
 
   
The sales charge normally  deducted on purchases  of Class A  shares is used  to
compensate  AIM  Distributors  and  participating  dealers  for  their  expenses
incurred in connections  with the  distribution of  the Funds'  Class A  shares.
Since  there  is  little  expenses  associated  with  unsolicited  orders placed
directly with AIM  Distributors by  persons who, because  of their  relationship
with  the Funds or with AIM and its  affiliates, are familiar with the Funds, or
whose programs for

purchase involve little expense  (e.g., because of the  size of the  transaction
and  shareholder  records  required),  AIM  Distributors  believes  that  it  is
appropriate and in  the Funds'  best interests  that such  persons, and  certain
other persons whose purchases result in relatively low expenses of distribution,
be  permitted to purchase Class  A shares of the  Funds through AIM Distributors
without payment of a sales charge. The  persons who may purchase Class A  shares
of the Funds without a sales charge are set forth in the Funds' Prospectuses. In
addition,  the Funds offer programs such as  Right of Accumulation and Letter of
Intent, which are  described in the  Prospectuses, that are  designed to  permit
investors  to aggregate purchases of different funds, or separate purchases over
time, in  order  to qualify  for  a lower  sales  charge rate.  See  "Terms  and
Conditions  of Purchase of the AIM Funds -- Reductions in Initial Sales Charges"
in the Prospectuses.
    
 
   
Class B shares will automatically convert into  Class A shares of the same  Fund
eight  years following  the end of  the calendar  month in which  a purchase was
made. For the purpose of calculating the holding period required for  conversion
of  Class B shares,  the initial issuance of  Class B shares  shall mean (i) the
date on  which such  Class B  shares were  issued, or  (ii) for  Class B  shares
obtained  through an exchange, or  a series of exchanges,  the date on which the
original Class B  shares were  issued. For purposes  of conversion  to Class  A,
Class  B  shares  purchased  through the  reinvestment  of  dividends  and other
distributions paid in  respect of  Class B  shares will  be held  in a  separate
sub-account.  Each time any Class B  shares in the shareholder's regular account
(other than those in the sub-account) convert to Class A, a pro rata portion  of
the  Class B shares in the sub-account will also convert to Class A. The portion
will be determined by the ratio that the shareholder's Class B shares converting
to Class A bears to the shareholder's total Class B shares not acquired  through
dividends and other distributions.
    
 
   
The  availability  of  the  conversion  feature  is  subject  to  the continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions  paid  on  Class  A  and  Class  B  shares  will  not  result   in
"preferential  dividends" under the Internal Revenue  Code and the conversion of
shares does not constitute a taxable event. If the conversion feature ceased  to
be available, the Class B shares beyond the eighth year. AIM and the Sub-adviser
has  no  reason to  believe  that this  condition  for the  availability  of the
conversion feature will not be met.
    
 
   
Class A shares that are subject to  a contingent deferred sales charge and  that
were  purchased before June 1,  1998 are entitled to  the following waivers from
the contingent deferred sales charge otherwise due upon redemption: (1)  minimum
required  distributions made in connection with  an IRA, Keogh Plan or custodial
account under Section  403(b) of  the Code  or other  retirement plan  following
attainment  of age  70 1/2;  (2) total or  partial redemptions  resulting from a
distribution   following   retirement   in   the   case   of   a   tax-qualified
employer-sponsored  retirement  plan;  (3)  when  a  redemption  results  from a
tax-free return of an excess contribution  pursuant to Section 408(d)(4) or  (5)
of  the Code or  from the death  or disability of  the employee; (4) redemptions
pursuant to the Fund's right to liquidate a shareholder's account involuntarily;
(5)   redemptions    pursuant   to    distributions   from    a    tax-qualified
employer-sponsored  retirement plan, which  is invested in  AIM Funds, which are
permitted to be made without penalty  pursuant to the Code, other than  tax-free
rollovers  or transfers of assets,  and the proceeds of  which are reinvested in
AIM  Funds;  (6)  redemptions  made  in  connection  with   participant-directed
exchanges between options in an employer-sponsored benefit plan; (7) redemptions
made  for the purpose  of providing cash  to fund a  loan to a  participant in a
tax-qualified retirement  plan;  (8)  redemptions  made  in  connection  with  a
distribution from any retirement plan or account that is permitted in accordance
with  the  provisions  of Section  72(t)(2)  of  the Code,  and  the regulations
promulgated thereunder; (9) redemptions made  in connection with a  distribution
from  any  retirement plan  or account  that  involves the  return of  an excess
deferral amount pursuant to Section 401(k)(8) or Section 402(g)(2) of the  Code;
(10)  redemptions  made  in  connection with  a  distribution  from  a qualified
profit-sharing or stock bonus plan described in Section 401(k) of the Code to  a
participant  or  beneficiary under  Section  401(k)(2)(B)(IV) of  the  Code upon
hardship of the  covered employee  (determined pursuant  to Treasury  Regulation
Section  1.401(k)-1(d)(2)); and (11)  redemptions made by or  for the benefit of
certain states, counties  or cities,  or any  instrumentalities, departments  or

For  purposes of  a Letter  of Intent entered  into prior  to June  1, 1998, any
registered investment  adviser, trust  company or  bank trust  department  which
exercises  investment  discretion and  which intends  within thirteen  months to
invest $500,000 or more can be  treated as a single purchaser, provided  further
that  such  entity places  all purchases  and  redemption orders.  Such entities
should be prepared to establish their qualifications for such treatment.
    
 
   
Complete information concerning the method of exchanging shares of the Funds for
shares of the other AIM Funds is set forth in the Prospectuses under the heading
"Exchange Privilege."
    
 
   
Information concerning  redemption of  the Funds'  shares is  set forth  in  the
Prospectuses under the heading "How to Redeem Shares." In addition to the Funds'
obligation  to redeem shares, AIM Distributors  may also repurchase shares as an
accommodation to shareholders. To  effect a repurchase,  those dealers who  have
executed  Selected Dealer Agreements with AIM  Distributors must phone orders to
the order desk  of the Funds  at (800)  959-4246 and guarantee  delivery of  all
required  documents in  good order.  A repurchase is  effected at  the net asset
value per share  of the  applicable Fund  next determined  after the  repurchase
order  is received. Such  an arrangement is subject  to timely receipt  by A I M
Fund Services, Inc.,  the Funds' transfer  agent, of all  required documents  in
good  order. If such documents  are not received within  a reasonable time after
the order is placed,  the order is  subject to cancellation.  While there is  no
charge  imposed by  a Fund  or by  AIM Distributors  (other than  any applicable
contingent deferred  sales  charge) when  shares  are redeemed  or  repurchased,
dealers may charge a fair service fee for handling the transaction.
    
 
   
The  right of redemption may be suspended  or the date of payment postponed when
(a) trading on  the NYSE is  restricted, as determined  by applicable rules  and
regulations  of the SEC, (b) the NYSE is closed for other than customary weekend
and holiday closings, (c) the SEC has by order permitted such suspension, or (d)
an emergency as  determined by the  SEC exists making  disposition of  portfolio
securities  or  the  valuation  of  the net  assets  of  a  Fund  not reasonably
practicable.
    
 
   
                QUALIFYING FOR A REDUCED FRONT-END SALES CHARGE
    
 
   
As described in each Prospectus, the  front-end sales charge for Class A  shares
is  calculated by multiplying  an investor's total  investment by the applicable
sales charge rate.  The applicable  rate varies  with the  amount invested.  The
Funds  offer programs such as Right of  Accumulation and Letter of Intent, which
are described  in  the Prospectus,  and  are  designed to  permit  investors  to
aggregate  purchases of  different funds,  or separate  purchases over  time, in
order to qualify for  a lower sales  charge rate. See  "Terms and Conditions  of
Purchase  of  the AIM  Funds  -- Reductions  in  Initial Sales  Charges"  in the
Prospectus.
    
 
   
                     PROGRAMS AND SERVICES FOR SHAREHOLDERS
    
 
   
The Funds provide certain  services for shareholders  and certain investment  or
redemption  programs. See "Exchange Privilege" and "How to Redeem Shares" in the
Prospectus. All inquiries concerning these  programs should be made directly  to

DIVIDEND ORDER.  Dividends may  be paid  to someone  other than  the  registered
owner, or sent to an address other than the address of record. (Please note that
signature  guarantees are required to effect  this option.) An investor also may
direct that his or her dividends be invested  in one of the AIM Funds and  there
is no sales charge for these investments; initial investment minimums apply. See
"Dividends, Distributions and Tax Matters -- Dividends and Distributions" in the
Prospectus.  To effect this  option, please contact  your authorized dealer. For
more information concerning  AIM Funds  other than  the Funds,  please obtain  a
current  prospectus by contacting  your authorized dealer,  by writing to  A I M

                                     TAXES
 
- --------------------------------------------------------------------------------
 
GENERAL
   
Each  Fund is treated as a separate corporation for federal income tax purposes.
To continue to qualify  for treatment as  a RIC under the  Code, each Fund  must
distribute  to  its shareholders  for  each taxable  year  at least  90%  of its
investment company  taxable  income  (consisting  generally  of  net  investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) ("Distribution  Requirement")  and must  meet  several  additional
requirements. These requirements include the following: (1) the Fund must derive
at  least 90% of  its gross income  each taxable year  from dividends, interest,
payments with  respect to  securities loans  and gains  from the  sale or  other
disposition  of  securities or  foreign currencies,  or other  income (including
gains from options, Futures  or Forward Contracts) derived  with respect to  its
business  of investing in securities or those currencies ("Income Requirement");
and (2) the Diversification Requirements.
    
 
   
Dividends and  other  distributions  declared  by a  Fund  in,  and  payable  to
shareholders  of record as  of a date  in, October, November  or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during  the following  January. Accordingly,  those distributions  will  be
taxed to shareholders for the year in which that December 31 falls.
    
 
If  Fund shares are sold at a loss after  being held for six months or less, the
loss will be treated  as long-term, instead of  short-term, capital loss to  the
extent  of any  capital gain distributions  received on  those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or other distribution, the shareholder will pay full price  for
the shares and receive some portion of the price back as a taxable distribution.
 
   
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent  it fails to distribute by the end of any calendar year substantially all
of its  ordinary income  for  that year  and capital  gain  net income  for  the
one-year period ending on October 31 of that year, plus certain other amounts.
    
 
FOREIGN TAXES
   
Dividends and interest received by each Fund, and gains realized thereby, may be
subject  to income, withholding or other  taxes imposed by foreign countries and
U.S. possessions  ("foreign taxes")  that would  reduce the  yield and/or  total
return  on its  securities. Tax  conventions between  certain countries  and the
United States may reduce or eliminate  foreign taxes, however, and many  foreign
countries  do not  impose taxes  on capital gains  in respect  of investments by
foreign investors. If more than 50% of the value of a Fund's total assets at the
close of its taxable  year consists of securities  of foreign corporations,  the
Fund  will be eligible to,  and may, file an  election with the Internal Revenue
Service that will enable its shareholders, in effect, to receive the benefit  of
the foreign tax credit with respect to any foreign taxes paid by it. Pursuant to
the  election,  the  Fund would  treat  those  taxes as  dividends  paid  to its
shareholders and each  shareholder would  be required  to (1)  include in  gross
income,  and treat as paid by him, his share of those taxes, (2) treat his share
of those taxes and of any dividend paid by the Fund that represents income  from
foreign  and U.S. possessions sources  as his own income  from those sources and
(3) either deduct the taxes deemed paid  by him in computing his taxable  income
or,  alternatively, use the foregoing information in calculating the foreign tax
credit against his federal income tax. Each Fund will report to its shareholders
shortly after each taxable  year their respective shares  of the Fund's  foreign
taxes  and income from sources within, and  taxes paid to, foreign countries and
U.S. possessions if it makes this election. Pursuant to the Taxpayer Relief  Act
of  1997 ("Tax Act"), individuals  who have no more  than $300 ($600 for married
persons filing jointly) of  creditable foreign taxes included  on Form 1099  and
all  of whose foreign source income is "qualified passive income" may elect each
year to be exempt from the  extremely complicated foreign tax credit  limitation
and  will be  able to  claim a  foreign tax  credit without  having to  file the
detailed Form 1116 that otherwise is required.
    
 
PASSIVE FOREIGN INVESTMENT COMPANIES
   
Each Fund may  invest in  the stock  of "passive  foreign investment  companies"
("PFICs").  A PFIC is a foreign corporation  -- other than a "controlled foreign
corporation" (I.E.,  a foreign  corporation  in which,  on  any day  during  its
taxable  year,  more than  50% of  the total  voting power  of all  voting stock
therein or the total value of  all stock therein is owned, directly,  indirectly

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
   
or  constructively,  by  "U.S.  shareholders,"  defined  as  U.S.  persons  that
individually own, directly, indirectly or  constructively, at least 10% of  that
voting  power) as to which a Fund  is a U.S. shareholder (effective with respect
to each  Fund for  its taxable  year beginning  November 1,  1998) --  that,  in
general,  meets either  of the following  tests: (1)  at least 75%  of its gross
income is passive or (2)  an average of at least  50% of its assets produce,  or
are  held for the production of,  passive income. Under certain circumstances, a
Fund will  be  subject  to federal  income  tax  on a  portion  of  any  "excess
distribution"  received on, or of  any gain from the  disposition of, stock of a
PFIC (collectively  "PFIC income"),  plus  interest thereon,  even if  the  Fund
distributes  the  PFIC income  as a  taxable dividend  to its  shareholders. The
balance of the  PFIC income will  be included in  the Fund's investment  company
taxable  income and,  accordingly, will not  be taxable  to it to  the extent it
distributes that income to its shareholders.
    
 
   
If a  Fund invests  in a  PFIC and  elects to  treat the  PFIC as  a  "qualified
electing  fund"  ("QEF"),  then  in  lieu  of  the  foregoing  tax  and interest
obligation, the Fund would be  required to include in  income each year its  pro
rata share of the QEF's ordinary earnings and net capital gain (I.E., the excess
of  net long-term capital gain  over net short-term capital  loss) -- which most
likely would have  to be  distributed by the  Fund to  satisfy the  Distribution
Requirement and avoid imposition of the Excise Tax -- even if those earnings and
gain  were not received by the  Fund from the QEF. In  most instances it will be
very difficult, if  not impossible,  to make  this election  because of  certain
requirements thereof.
    
 
   
Effective  for its taxable year beginning November  1, 1998, each Fund may elect
to "mark to market" its stock in any PFIC. "Marking-to-market," in this context,
means including in ordinary income each taxable year the excess, if any, of  the
fair  market value of the  stock over a Fund's adjusted  basis therein as of the
end of that  year. Pursuant  to the  election, a Fund  also will  be allowed  to
deduct  (as an ordinary, not capital, loss)  the excess, if any, of its adjusted
basis in  PFIC stock  over  the fair  market value  thereof  as of  the  taxable
year-end, but only to the extent of any net mark-to-market gains with respect to
that  stock included  in income by  the Fund  for prior taxable  years. A Fund's
adjusted basis in each PFIC's stock subject to the election will be adjusted  to
reflect  the  amounts  of  income  included  and  deductions  taken  thereunder.
Regulations proposed in  1992 provided a  similar election with  respect to  the
stock of certain PFICs.
    
 
NON-U.S. SHAREHOLDERS
   
Dividends  paid by a  Fund to a shareholder  who, as to the  United States, is a
nonresident alien individual, nonresident alien fiduciary of a trust or  estate,
foreign  corporation  or foreign  partnership ("foreign  shareholder") generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply, however, to a  dividend paid by a Fund to a  foreign
shareholder  that is "effectively connected with the  conduct of a U.S. trade or
business," in which case the  reporting and withholding requirements  applicable
to  domestic shareholders will  apply. A distribution  of net capital  gain by a
Fund to a foreign shareholder generally  will be subject to U.S. federal  income
tax  (at the rates applicable  to domestic persons) only  if the distribution is
"effectively connected"  or the  foreign shareholder  is treated  as a  resident
alien individual for federal income tax purposes.
    
 
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS
   
Each  Fund's  use  of  hedging  transactions,  such  as  selling  (writing)  and
purchasing options and  Futures and  entering into  Forward Contracts,  involves
complex  rules that will determine, for federal income tax purposes, the amount,
character and timing of recognition of the  gains and losses a Fund realizes  in
connection  therewith. Gains from the  disposition of foreign currencies (except
certain gains  that may  be  excluded by  future  regulations), and  gains  from
options,  Futures and Forward  Contracts derived by  a Fund with  respect to its
business of  investing in  securities  or foreign  currencies, will  qualify  as
permissible income under the Income Requirement.
    
 
   
Futures  and Forward  Contracts that  are subject  to section  1256 of  the Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts") and that are held by a Fund at the end of its taxable year generally
will be deemed to have been sold at that time at market value for federal income
tax  purposes. Sixty percent of any net  gain or loss recognized on these deemed
sales, and 60% of any net gain or loss realized from any actual sales of Section
1256 Contracts,  will be  treated as  long-term capital  gain or  loss, and  the
balance  will be treated  as short-term capital  gain or loss.  That 60% portion
will qualify for the  reduced maximum tax rates  on noncorporate taxpayers'  net
capital  gain  enacted by  the Tax  Act --  20%  (10% for  taxpayers in  the 15%
marginal tax bracket) for gain recognized  on capital assets held for more  than
18  months -- instead of  the 28% rate in  effect before that legislation, which
now applies to gain recognized on capital assets held for more than one year but
not more than 18 months.
    
 
Section 988 of the Code also may apply to gains and losses from transactions  in
foreign  currencies, foreign-currency-denominated  debt securities  and options,
Futures and Forward  Contracts on  foreign currencies ("Section  988" gains  and
losses).  Each Section  988 gain  or loss  generally is  computed separately and
treated as ordinary income or loss. In the case

                         AIM LATIN AMERICAN GROWTH FUND
   
of overlap  between sections  1256  and 988,  special provisions  determine  the
character  and timing of any income, gain  or loss. The Funds attempt to monitor
section 988 transactions to minimize any adverse tax impact.
    
 
   
If a Fund  has an  "appreciated financial  position" --  generally, an  interest
(including  an interest through an option,  Futures or Forward Contract or short
sale) with respect to any stock, debt instrument (other than "straight debt") or
partnership interest the fair market value  of which exceeds its adjusted  basis
- --  and enters into a  "constructive sale" of the  same or substantially similar
property, the Fund will be treated as  having made an actual sale thereof,  with
the  result  that gain  will be  recognized  at that  time. A  constructive sale
generally consists of a short sale, an offsetting notional principal contract or
Futures or Forward  Contract entered into  by a  Fund or a  related person  with
respect  to  the same  or substantially  similar property.  In addition,  if the
appreciated financial  position is  itself  a short  sale  or such  a  contract,
acquisition of the underlying property or substantially similar property will be
deemed a constructive sale.
    
 
   
The  foregoing  is a  general  and abbreviated  summary  of certain  federal tax
considerations affecting each Fund and its shareholders. Investors are urged  to
consult their own tax advisers for more detailed information and for information
regarding  any  foreign,  state  and  local  taxes  applicable  to distributions
received from the Funds.

- --------------------------------------------------------------------------------
 
   
AIM was organized in 1976, and  along with its subsidiaries, manages or  advises
approximately  90 investment  company portfolios  encompassing a  broad range of
investment objectives.  AIM  is a  direct,  wholly owned  subsidiary  of A  I  M
Management  Group  Inc.  ("AIM Management"),  a  holding company  that  has been
engaged in  the  financial  services  business  since  1976.  AIM  is  the  sole
shareholder   of  the  Fund's  principal   underwriter,  AIM  Distributors.  AIM
Management is an indirect wholly owned subsidiary of AMVESCAP PLC, 11 Devonshire
Square, London, EC2M  4YR, England.  AMVESCAP PLC  and its  subsidiaries are  an
independent  investment management group that has  a significant presence in the
institutional and retail segment of the investment management industry in  North
America and Europe, and a growing presence in Asia.
    
 
CUSTODIAN
   
State  Street  Bank and  Trust Company  ("State  Street"), 225  Franklin Street,
Boston, MA  02110, acts  as custodian  of each  Fund's assets.  State Street  is
authorized  to  establish  and  has  established  separate  accounts  in foreign
currencies and to cause securities of each Fund to be held in separate  accounts
outside the United States in the custody of non-U.S. banks.
    
 
INDEPENDENT ACCOUNTANTS
   
The  Funds'  independent accountants  are                                      .
                        conducts an annual  audit of each  Fund, assists in  the
preparation of the Funds' federal and state income tax returns and consults with
the  Company and the Funds as to  matters of accounting, regulatory filings, and
federal and state income taxation.
    
 
   
The audited financial statements  of the Company included  in this Statement  of
Additional Information have been examined by                         , as stated
in their opinion appearing herein and are included in reliance upon such opinion
given upon the authority of that firm as experts in accounting and auditing.
    
 
   
SHAREHOLDER LIABILITY
    
   
Under  Delaware law,  the shareholders of  the Trust enjoy  the same limitations
extended to shareholders of private, for-profit corporations. There is a  remote
possibility, however, that under certain circumstances shareholders of the Trust
may  be held personally  liable for the Trust's  obligations. However, the Trust
Agreement disclaims shareholder liability for  acts or obligations of the  Trust
and  requires  that  notice  of  such disclaimer  be  given  in  each agreement,
obligation or instrument entered into or executed by the Trust or a trustee. The
Trust Agreement provides  for indemnification  from the Trust  property for  all
losses  and expenses of  any shareholder held personally  liable for the Trust's
obligations. Thus, the risk of a shareholder incurring financial loss on account
of such liability is limited to circumstances in which the Trust itself would be
unable to meet  its obligations and  where the other  party was held  not to  be
bound by the disclaimer.

TOTAL RETURN QUOTATIONS
    
   
The  standard  formula  for  calculating  total  return,  as  described  in each
Prospectus, is as follows:

Where      P   =      a hypothetical initial payment of $1,000.
           T   =      average annual total return  (assuming the applicable maximum  sales load is deducted  at
                      the beginning of the 1, 5, or 10 year periods).
           n   =      number of years.
           ERV =      ending  redeemable value of a hypothetical  $1,000 payment at the end  of the 1, 5, or 10
                      year periods (or fractional portion of such period).

OTHER  INFORMATION REGARDING STANDARD  TOTAL AND NON-STANDARD  TOTAL RETURNS FOR
DEVELOPING MARKETS FUND
    
   
The standard total and non-standard total return data of Developing Markets Fund
are based on the performance of the Predecessor Fund as a closed-end  investment
company.  The  standard  total return  data,  however, have  been  recomputed to
reflect the deduction of the current maximum  sales charge of 4.75% for Class  A
shares  which  went  into effect  on  November  1, 1997.  Future  performance of
Developing Markets Fund will  be effected by  expenses that it  will incur as  a
series of an open-end investment company.

Each Fund may also compare its  performance to rates on Certificates of  Deposit
and other fixed rate investments such as the following:
    
 
   
         10-year Treasuries
       30-year Treasuries
       30-day Treasury Bills
    
 
   
Information   relating  to   foreign  market   performance,  capitalization  and
diversification is based on sources believed  to be reliable but may be  subject
to  revision  and  has not  been  independently  verified by  the  Funds  or AIM
Distributors.  Advertising  for  the  Funds  may  from  time  to  time   include
discussions  of general economic conditions  and interest rates. Advertising for
the Funds may also  include reference to the  use of those Funds  as part of  an
individual's  overall retirement  investment program.  From time  to time, sales
literature and/or  advertisements for  any of  the Funds  may disclose  (i)  the
largest  holdings in  the Fund's portfolio,  (ii) certain  selling group members
and/or (iii) certain institutional shareholders.
    
 
   
From time to time, the Funds' sales literature and/or advertisements may discuss
generic topics pertaining to the mutual fund industry. This includes, but is not
limited to,  literature  addressing  general  information  about  mutual  funds,
variable   annuities,  dollar-cost  averaging,  stocks,  bonds,  money  markets,
certificates  of  deposit,  retirement,  retirement  plans,  asset   allocation,
tax-free investing, college planning, and inflation.
    
 
   
Although  performance data may be useful to prospective investors when comparing
a Fund's performance with other funds and other potential investments, investors
should note  that  the  methods  of computing  performance  of  other  potential
investments are not necessarily comparable to the methods employed by a Fund.

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by  various entities from "Aaa"  to "C." Investment grade  ratings are the first
four categories:
 
        Aaa -- Bonds which are rated Aaa  are judged to be of the best  quality.
    They carry the smallest degree of investment risk and are generally referred
    to  as "gilt  edged." Interest payments  are protected  by a large  or by an
    exceptionally stable  margin  and principal  is  secure. While  the  various
    protective  elements are likely to change, such changes as can be visualized
    are most  unlikely  to impair  the  fundamentally strong  position  of  such
    issues.
 
        Aa  -- Bonds which are rated Aa are  judged to be of high quality by all
    standards. Together  with the  Aaa group  they comprise  what are  generally
    known  as high grade bonds. They are  rated lower than the best bond because
    margins of  protection  may  not  be  as  large  as  in  Aaa  securities  or
    fluctuation  of protective elements may be of greater amplitude or there may
    be other  elements present  which make  the long-term  risk appear  somewhat
    larger than the Aaa securities.
 
        A  --  Bonds  which  are  rated  A  possess  many  favorable  investment
    attributes and  are  to  be considered  as  upper-medium-grade  obligations.
    Factors  giving security to principal  and interest are considered adequate,
    but elements may  be present  which suggest a  susceptibility to  impairment
    some time in the future.
 
        Baa  --  Bonds  which  are  rated  Baa  are  considered  as medium-grade
    obligations, (i.e., they are neither  highly protected nor poorly  secured).
    Interest payments and principal security appear adequate for the present but
    certain  protective  elements may  be lacking  or may  be characteristically
    unreliable over  any  great length  of  time. Such  bonds  lack  outstanding
    investment  characteristics and in fact  have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative  elements;
    their  future cannot be considered as  well-assured. Often the protection of
    interest and principal payments may be  very moderate, and thereby not  well
    safeguarded  during other good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B --  Bonds which  are rated  B generally  lack characteristics  of  the
    desirable  investment. Assurance  of interest  and principal  payments or of
    maintenance of other terms of the contract over any long period of time  may
    be small.
 
        Caa  -- Bonds which are rated Caa  are of poor standing. Such issues may
    be in default or  there may be  present elements of  danger with respect  to
    principal or interest.
 
        Ca  --  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are  rated C are the lowest  rated class of bonds,  and
    issues  so rated can be regarded as  having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has  been
suspended  or withdrawn, it may  be for reasons unrelated  to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer  belongs to a group  of securities or companies  that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
Suspension  or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data  to permit  a judgment  to be  formed; if  a bond  is
called for redemption; or for other reasons.
 
Note:  Moody's applies numerical  modifiers, 1, 2  and 3 in  each generic rating
classification from Aa to Caa. The  modifier 1 indicates that the Company  ranks
in  the higher end  of its generic  rating category; the  modifier 2 indicates a
mid-range ranking; and the  modifier 3 indicates that  the Company ranks in  the
lower end of its generic rating category.
 
    STANDARD  & POOR'S, a  division of The  McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various  entities in categories ranging from  "AAA"
to  "D"  according  to quality.  Investment  grade  ratings are  the  first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA  --  An  obligation  rated  "AA"  differs  from  the  highest   rated
    obligations  only  in a  small degree.  The obligor's  capacity to  meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB  --  An   obligation  rated  "BBB"   exhibits  adequate   protection
    parameters.  However, adverse economic  conditions or changing circumstances
    are more likely to lead  to a weakened capacity of  the obligor to meet  its
    financial commitment on the obligation.
 
        BB,  B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and "C"
    are  regarded  as  having  significant  speculative  characteristics.   "BB"
    indicates  the least degree  of speculation and "C"  the highest. While such
    obligations will likely  have some quality  and protective  characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB  -- An  obligation rated "BB"  is less vulnerable  to nonpayment than
    other speculative issues. However, it  faces major ongoing uncertainties  or
    exposure  to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate  capacity to meet its financial  commitment
    on the obligation.
 
        B  --  An obligation  rated "B"  is more  vulnerable to  nonpayment than
    obligations rated "BB," but the obligor  currently has the capacity to  meet
    its  financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to  nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for  the obligor to meet its financial  commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to  have the  capacity to meet  its financial  commitment on  the
    obligation.
 
        CC  --  An  obligation  rated "CC"  is  currently  highly  vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a  bankruptcy
    petition  has been filed or  similar action has been  taken, but payments on
    this obligation are being continued.
 
        D --  An obligation  rated "D"  is in  payment default.  The "D"  rating
    category is used when payments on an obligation are not made on the date due
    even  if the  applicable grace period  has not expired,  unless S&P believes
    that such payments  will be made  during such grace  period. The "D"  rating
    also  will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by  the
addition  of a  plus or minus  sign to  show relative standing  within the major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient  information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs  the  designation  "Prime-1" to  indicate  commercial  paper
having  a superior ability for repayment  of senior short-term debt obligations.
Prime-1 repayment  ability will  often be  evidenced by  many of  the  following
characteristics:  leading market positions  in well-established industries; high
rates of return  on funds employed;  conservative capitalization structure  with
moderate  reliance on debt and ample asset protection; broad margins in earnings
coverage of

                          AIM DEVELOPING MARKETS FUND
                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
fixed financial charges and high internal cash generation; and  well-established
access  to  a  range  of  financial markets  and  assured  sources  of alternate
liquidity. Issues rated Prime-2  have a strong ability  for repayment of  senior
short-term  debt obligations.  This normally  will be  evidenced by  many of the
characteristics cited above but to a lesser degree. Earnings trends and coverage
ratios,  while  sound,  may  be   more  subject  to  variation.   Capitalization
characteristics,  while  still appropriate,  may  be more  affected  by external
conditions. Ample alternate liquidity is maintained.
 
   
    S&P ratings of commercial paper  are graded into several categories  ranging
from  "A1" for the highest quality obligations  to "D" for the lowest. Issues in
the "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate  the
relative  degree  of safety.  A-1 --  This highest  category indicates  that the
degree of safety regarding timely payment is strong. Those issues determined  to
possess extremely strong safety characteristics will be denoted with a plus sign
(+)  designation.  A-2  -- Capacity  for  timely  payments on  issues  with this
designation is satisfactory; however,  the relative degree of  safety is not  as
high as for issues designated "A-1."

This  Statement of Additional  Information relates solely  to the Class  A and B

The term "majority of the outstanding shares" of the Trust, of a particular Fund
or of  a  particular  class of  a  Fund  or of  a  particular  Portfolio  means,
respectively,  the vote of  the lesser of (a)  67% or more of  the shares of the
Trust, such Fund or such class present at a meeting of the Trust's shareholders,
if the holders of  more than 50%  of the outstanding shares  of the Trust,  such
Fund  or such class are present or represented by proxy, or (b) more than 50% of
the outstanding shares of the Trust, such Fund or such class.
    
 
   
Class A, Class B  and Advisor Class  shares of each Fund  have equal rights  and
privileges.  Each  share of  a  particular class  is  entitled to  one  vote, to
participate equally in dividends and distributions declared by the Trust's Board
of Trustees with respect to the class of such Fund and, upon liquidation of  the
Fund,  to participate proportionately in the net assets of the Fund allocable to
such class remaining after satisfaction  of outstanding liabilities of the  Fund
allocable  to such class.  Fund shares are fully  paid, non-assessable and fully
transferable when issued and have no preemptive rights and have such  conversion
and  exchange  rights as  set  forth in  the  Prospectus and  this  Statement of
Additional Information. Fractional shares have proportionately the same  rights,
including voting rights, as are provided for a full share.
    
 
   
Shareholders  of the Funds  do not have cumulative  voting rights, and therefore
the holders of  more than  50% of  the outstanding  shares of  all Funds  voting
together  for election of directors may elect all of the members of the Board of
Trustees of the  Trust. In such  event, the remaining  holders cannot elect  any
trustees of the Trust.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES
The  investment objective of  each Feeder Fund is  long-term capital growth. The
investment objective  of the  Health Care  Fund and  Telecommunications Fund  is
long-term capital appreciation and long-term growth of capital, respectively.
 
   
Each  Feeder Fund seeks to achieve its  investment objective by investing all of
its investable assets in a Portfolio, each  of which is a subtrust (a  "series")
of Global Investment Portfolio (an open-end management investment company), with
an  investment objective that  is identical to that  of its corresponding Feeder
Fund. Whenever the phrase "all of a Fund's investable assets" is used herein and
in the Prospectus, it means that the only investment securities held by a Feeder
Fund will be  its interest  in its corresponding  Portfolio. A  Feeder Fund  may
withdraw its investment in its corresponding Portfolio at any time, if the Board
of Trustees of the Trust determines that it is in the best interests of the Fund
and  its shareholders to do so. Upon any such withdrawal, a Feeder Fund's assets
would  be  invested  in   accordance  with  the   investment  policies  of   its
corresponding Portfolio described below and in the Prospectus.
    
 
SELECTION OF EQUITY INVESTMENTS
With  respect to  the Resources Portfolio,  the Sub-adviser  has identified four
areas that  it  expects  will create  investment  opportunities:  (i)  improving
supply/demand  fundamentals, which may  result in higher  commodity prices; (ii)
privatization of state-owned natural resource businesses; (iii) management which
can improve production efficiencies without correspondingly increasing commodity
prices; and (iv) service companies  with emerging technologies that can  enhance
productivity  or reduce production costs. Of  course, there is no certainty that
these factors will produce the anticipated results.
 
With respect to the Telecommunications Fund, the Sub-adviser has identified four
areas that it expects will create investment opportunities: (i) deregulation  of
companies  in  the industry,  which will  allow  competition to  promote greater
efficiencies; (ii) privatization  of state-owned telecommunications  businesses;
(iii) development of infrastructure in underdeveloped countries and upgrading of
services  in other countries;  and (iv) emerging  technologies that will enhance
productivity and reduce  costs in  the telecommunications  industry. Of  course,
there is no certainty that these factors will produce the anticipated results.
 
There  may be times when, in the  opinion of the Sub-adviser, prevailing market,
economic or political conditions  warrant reducing the  proportion of the  Theme
Portfolios'  assets invested in equity  securities and increasing the proportion
held in cash (U.S. dollars, foreign currencies or multinational currency  units)
or  invested in debt securities or  high quality money market instruments issued
by corporations, or the U.S., or a  foreign government. A portion of each  Theme
Portfolio's  assets  normally  will  be  held  in  cash  (U.S.  dollars, foreign
currencies  or   multinational   currency   units)  or   invested   in   foreign
 
                   Statement of Additional Information Page 4
<PAGE>
                             AIM GLOBAL THEME FUNDS
or domestic high quality money market instruments pending investment of proceeds
from  new sales of  Fund shares to  provide for ongoing  expenses and to satisfy
redemptions.
 
For  each  Theme  Portfolio's  investment  purposes,  an  issuer  is   typically
considered  as located in a particular country  if it (a) is organized under the
laws of or has  its principal office  in a particular  country, or (b)  normally
derives  50%  or more  of  its total  revenues  from business  in  that country,
provided that, in the Sub-adviser's view, the value of such issuer's  securities
will  tend  to  reflect such  country's  development  to a  greater  extent than
developments elsewhere.  However,  these  are  not  absolute  requirements,  and
certain  companies incorporated  in a particular  country and  considered by the
Sub-adviser  to  be  located  in  that  country  may  have  substantial  foreign
operations  or subsidiaries and/or export sales  exceeding in size the assets or
sales in that country.
 
In  certain  countries,  governmental  restrictions  and  other  limitations  on
investment  may affect a Theme Portfolio's  ability to invest in such countries.
In addition,  in  some instances  only  special  classes of  securities  may  be
purchased by foreigners and the market prices, liquidity and rights with respect
to  those securities may vary from shares owned by nationals. The Sub-adviser is
not aware at this time  of the existence of  any investment or exchange  control
regulations  which  might  substantially  impair  the  operations  of  the Theme
Portfolios as  described in  the  Prospectus and  this Statement  of  Additional
Information.  Restrictions may  in the future,  however, make  it undesirable to
invest in  certain  countries.  None  of the  Theme  Portfolios  has  a  present
intention of making any significant investment in any country or stock market in
which  the Sub-adviser considers the political or economic situation to threaten
a Theme  Portfolio with  substantial or  total loss  of its  investment in  such
country or market.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
Each  Theme  Portfolio  may invest  in  the securities  of  investment companies
(including investment vehicles or  companies advised by  the Sub-adviser or  its
affiliates ("Affiliated Funds")) within the limits of the Investment Company Act
of  1940, as amended (the "1940 Act"). These limitations currently provide that,
in general,  a Theme  Portfolio may  purchase shares  of an  investment  company
unless (a) such a purchase would cause a Theme Portfolio to own in the aggregate
more  than 3% of the total outstanding voting stock of the investment company or
(b) such a purchase would cause the Theme Portfolio to have more than 5% of  its
assets  invested  in the  investment  company or  more  than 10%  of  its assets
invested in  an  aggregate  of  all such  investment  companies.  The  foregoing
restrictions  do not  apply to  the investment  of the  Financial Services Fund,
Infrastructure Fund, Resources Fund and  Consumer Products and Services Fund  in
their  corresponding Portfolios.  Investment in  closed-end investment companies
may involve  the  payment  of  substantial premiums  above  the  value  of  such
companies'  portfolio securities. Each Theme Portfolio does not intend to invest
in such investment  companies unless, in  the judgment of  the Sub-adviser,  the
potential  benefits of  such investments justify  the payment  of any applicable
premiums. The return on such securities will be reduced by operating expenses of
such  companies,  including  payments  to  the  investment  managers  of   those
investment  companies.  With respect  to  investments in  Affiliated  Funds, the
Sub-adviser waives its advisory fee  to the extent that  such fees are based  on
assets of a Theme Portfolio invested in Affiliated Funds.
 
   
DEPOSITARY RECEIPTS
    
   
A Theme Portfolio may hold securities of foreign issuers in the form of American
Depositary  Receipts  ("ADRs"),  American  Depositary  Shares  ("ADSs"),  Global
Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs") or  other
securities  convertible  into  securities  of  eligible  foreign  issuers. These
securities may  not necessarily  be  denominated in  the  same currency  as  the
securities  for which they may be exchanged.  ADRs and ADSs are typically issued
by an  American bank  or  trust company  and  evidence ownership  of  underlying
securities  issued by a foreign corporation.  EDRs, which are sometimes referred
to as Continental Depositary Receipts  ("CDRs"), are issued in Europe  typically
by foreign banks and trust companies and evidence ownership of either foreign or
domestic  securities.  GDRs are  similar to  EDRs  and are  designed for  use in
several international financial markets. Generally, ADRs and ADSs in  registered
form are designed for use in U.S. securities markets and EDRs in bearer form are
designed  for use  in European  securities markets.  For purposes  of each Theme
Portfolio's investment policies, a Theme Portfolio's investments in ADRs,  ADSs,
GDRs  and  EDRs  will be  deemed  to  be investments  in  the  equity securities
representing securities of foreign issuers into which they may be converted.
    
 
ADR facilities may be established as either "unsponsored" or "sponsored."  While
ADRs  issued under these two  types of facilities are  in some respects similar,
there are distinctions between  them relating to the  rights and obligations  of
ADR holders and the practices of market participants. A depository may establish
an  unsponsored  facility  without  participation by  (or  even  necessarily the
acquiescence of) the issuer of the deposited securities, although typically  the
depository  requests a  letter of  non-objection from  such issuer  prior to the
establishment of the facility.  Holders of unsponsored  ADRs generally bear  all
the  costs  of such  facilities. The  depository usually  charges fees  upon the
deposit and withdrawal of the deposited securities, the conversion of  dividends
into   U.S.  dollars,  the  disposition   of  non-cash  distributions,  and  the
 
                   Statement of Additional Information Page 5
<PAGE>
                             AIM GLOBAL THEME FUNDS
performance of  other  services.  The  depository  of  an  unsponsored  facility
frequently  is  under  no obligation  to  distribute  shareholder communications
received from the issuer of the  deposited securities or to pass-through  voting
rights  to ADR  holders in  respect of  the deposited  securities. Sponsored ADR
facilities are created in generally  the same manner as unsponsored  facilities,
except  that  the  issuer of  the  deposited  securities enters  into  a deposit
agreement with the  depository. The deposit  agreement sets out  the rights  and
responsibilities  of  the  issuer,  the depository  and  the  ADR  holders. With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository), although ADR holders continue to bear certain other costs (such  as
deposit  and withdrawal fees).  Under the terms  of most sponsored arrangements,
depositories agree  to distribute  notices of  shareholder meetings  and  voting
instructions, and to provide shareholder communications and other information to
the  ADR holders at the  request of the issuer  of the deposited securities. The
Theme Portfolios may invest in both sponsored and unsponsored ADRs.
 
WARRANTS OR RIGHTS
Warrants or rights may be acquired by a Theme Portfolio in connection with other
securities or  separately and  provide the  Theme Portfolio  with the  right  to
purchase at a later date other securities of the issuer.
 
LENDING OF PORTFOLIO SECURITIES
For  the purpose of  realizing additional income, each  Theme Portfolio may make
secured loans of its securities holdings amounting  to not more than 30% of  its
total  assets.  Securities loans  are  made to  broker/dealers  or institutional
investors pursuant  to  agreements  requiring that  the  loans  be  continuously
secured by collateral at least equal at all times to the value of the securities
lent  plus any accrued interest, "marked to  market" on a daily basis. The Theme
Portfolios may pay  reasonable administrative and  custodial fees in  connection
with  the loans of their securities. While the securities loan is outstanding, a
Theme Portfolio  will continue  to receive  the equivalent  of the  interest  or
dividends  paid by  the issuer  on the  securities, as  well as  interest on the
investment of the collateral or a fee from the borrower. A Theme Portfolio  will
have  a right  to call  each loan  and obtain  the securities  within the stated
settlement period. A  Theme Portfolio  will not have  the right  to vote  equity
securities  while they are being lent, but it may call in a loan in anticipation
of any  important  vote.  Loans  will  only be  made  to  firms  deemed  by  the
Sub-adviser  to be of good standing and will not be made unless, in the judgment
of the Sub-adviser, the consideration to be earned from such loans would justify
the risk.
 
MONEY MARKET INSTRUMENTS
Money market instruments in which the  Theme Portfolios may invest include  U.S.
government   securities,  high-grade  commercial  paper,  bank  certificates  of
deposit, bankers' acceptances and  repurchase agreements related  to any of  the
foregoing. "High-grade commercial paper" refers to commercial paper rated A-1 by
Standard  & Poor's,  a division  of The McGraw-Hill  Companies, Inc.,  or P-1 by
Moody's Investors Services, Inc. or, if not rated, determined by the Sub-adviser
to be of comparable quality.
 
COMMERCIAL BANK OBLIGATIONS
For the purposes of each Theme  Portfolio's investment policies with respect  to
bank  obligations, obligations of foreign branches  of U.S. banks and of foreign
banks are obligations of the issuing bank and may be general obligations of  the
parent  bank.  Such obligations  may,  however, be  limited  by the  terms  of a
specific obligation  and  by  government  regulation.  As  with  investments  in
non-U.S.  securities  in  general,  investments in  the  obligations  of foreign
branches of U.S. banks and of foreign banks may subject each Theme Portfolio  to
investment  risks that are different in  some respects from those of investments
in obligations of  U.S. issuers.  Although each Theme  Portfolio will  typically
acquire  obligations issued and supported by the credit of U.S. or foreign banks
having total assets  at the  time of  purchase of $1  billion or  more, this  $1
billion  figure  is  not  an  investment policy  or  restriction  of  each Theme
Portfolio. For  the purposes  of  calculation with  respect  to the  $1  billion
figure,  the assets of a bank  will be deemed to include  the assets of its U.S.
and non-U.S. branches.
 
REPURCHASE AGREEMENTS
   
A repurchase agreement is a transaction  in which a Theme Portfolio purchases  a
security  from a bank or recognized securities dealer and simultaneously commits
to resell that security to the bank or dealer at an agreed upon price, date, and
market rate  of  interest  unrelated to  the  coupon  rate or  maturity  of  the
purchased  security.  Although  repurchase agreements  carry  certain  risks not
associated with direct investments in securities, including possible decline  in
the  market value of the underlying securities and delays and costs to the Theme
Portfolio if the other party to  the repurchase agreement becomes bankrupt,  the
Theme  Portfolios intend to enter into repurchase agreements only with banks and
dealers  believed  by  the  Sub-adviser  to  present  minimal  credit  risks  in
accordance  with guidelines established by the  Trust's or the Portfolios' Board
of Trustees,  as  applicable.  The  Sub-adviser  will  review  and  monitor  the
creditworthiness  of  such  institutions under  the  applicable  Board's general
supervision.
    
 
                   Statement of Additional Information Page 6
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
Each Theme Portfolio will invest only in repurchase agreements collateralized at
all times in  an amount  at least  equal to  the repurchase  price plus  accrued
interest.  To the extent that the proceeds from any sale of such collateral upon
a default in the obligation to repurchase were less than the repurchase price, a
Theme Portfolio would suffer a loss. If the financial institution which is party
to the  repurchase  agreement  petitions for  bankruptcy  or  otherwise  becomes
subject   to  bankruptcy  or   other  liquidation  proceedings,   there  may  be
restrictions on a Theme Portfolio's ability  to sell the collateral and a  Theme
Portfolio  could suffer a loss. However,  with respect to financial institutions
whose bankruptcy or liquidation proceedings  are subject to the U.S.  Bankruptcy
Code,  each Theme  Portfolio intends to  comply with provisions  under such Code
that would allow the immediate resale  of such collateral. Each Theme  Portfolio
will  not enter into a  repurchase agreement with a  maturity of more than seven
days if, as a result, more than 15%  of the value of its net assets (except  for
Health  Care Fund,  more than  10% of the  value of  its total  assets) would be
invested in such repurchase agreements and other illiquid investments.
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
Each Theme Portfolio's borrowings will not  exceed 33 1/3% of its total  assets,
i.e.,  the Theme Portfolio's total assets at  all times will equal at least 300%
of the amount of outstanding borrowings. If market fluctuations in the value  of
a  Theme Portfolio's securities holdings  or other factors cause  the ratio of a
Theme Portfolio's total  assets to  outstanding borrowings to  fall below  300%,
within  three days  (excluding Sundays  and holidays)  of such  event that Theme
Portfolio may be required to sell portfolio securities to restore the 300% asset
coverage, even  though  from  an  investment  standpoint  such  sales  might  be
disadvantageous.  Each Theme  Portfolio may  also borrow up  to 5%  of its total
assets for temporary or emergency purposes  other than to meet redemptions.  Any
borrowing by a Theme Portfolio may cause greater fluctuation in the value of its
shares than would be the case if that Theme Portfolio did not borrow.
 
   
Each  Theme  Portfolio's  fundamental investment  limitations  permit  the Theme
Portfolio to borrow money for leveraging purposes. However, each Theme Portfolio
(except the  Health Care  Fund)  is currently  prohibited,  pursuant to  a  non-
fundamental  investment  policy,  from  borrowing  money  in  order  to purchase
securities. Nevertheless,  this policy  may  be changed  in  the future  by  the
Trust's  or  the  Portfolios'  Board  of Trustees,  as  applicable.  If  a Theme
Portfolio employs  leverage  in the  future,  it  would be  subject  to  certain
additional  risks. Use of leverage creates  an opportunity for greater growth of
capital but would exaggerate any increases  or decreases in the net asset  value
of  the Financial Services  Fund, Infrastructure Fund,  Resources Fund, Consumer
Products and Services Fund or  a Theme Portfolio. When  the income and gains  on
securities  purchased with the  proceeds of borrowings exceed  the costs of such
borrowings, a  Theme Portfolio's  earnings  or a  Fund's  net asset  value  will
increase faster than otherwise would be the case; conversely, if such income and
gains  fail to exceed such  costs, a Theme Portfolio's  earnings or a Fund's net
asset value would decline faster than would otherwise be the case.
    
 
Each Theme Portfolio  may enter  into reverse repurchase  agreements. A  reverse
repurchase agreement is a borrowing transaction in which the Portfolio transfers
possession  of a security to another party,  such as a bank or broker/dealer, in
return for cash,  and agrees  to repurchase  the security  in the  future at  an
agreed  upon price, which  includes an interest  component. Each Theme Portfolio
may also engage  in "roll"  borrowing transactions,  which involve  the sale  of
Government  National  Mortgage  Association  certificates  or  other  securities
together with a commitment (for which the Theme Portfolio may receive a fee)  to
purchase  similar, but  not identical, securities  at a future  date. Each Theme
Portfolio will  segregate with  a custodian,  cash or  liquid securities  in  an
amount sufficient to cover its obligations under "roll" transactions and reverse
repurchase  agreements  with  broker/dealers.  No  segregation  is  required for
reverse repurchase agreements with banks.
 
SHORT SALES
Each Theme Portfolio  may make  short sales  of securities.  A short  sale is  a
transaction in which a Theme Portfolio sells a security in anticipation that the
market  price of that  security will decline.  A Theme Portfolio  may make short
sales (i) as a form of hedging to offset potential declines in long positions in
securities it owns, or anticipates acquiring, or in similar securities, and (ii)
in order to maintain flexibility in its securities holdings.
 
When a Theme Portfolio makes a short sale of a security it does not own, it must
borrow the security  sold short  and deliver it  to the  broker/dealer or  other
intermediary  through which it made the short sale. The Theme Portfolio may have
to pay a fee to borrow particular securities and will often be obligated to  pay
over any payments received on such borrowed securities.
 
A  Theme  Portfolio's  obligation  to replace  the  borrowed  security  when the
borrowing is called or expires will be secured by collateral deposited with  the
intermediary.  The Theme Portfolio  will also be  required to deposit collateral
with its custodian to the  extent, if any, necessary so  that the value of  both
collateral  deposits in the aggregate is at all  times equal to at least 100% of
the current market value of the  security sold short. Depending on  arrangements
made with the
 
                   Statement of Additional Information Page 7
<PAGE>
                             AIM GLOBAL THEME FUNDS
intermediary  from  which  it borrowed  the  security regarding  payment  of any
amounts received by that Theme Portfolio on such security, a Theme Portfolio may
not receive any payments (including  interest) on its collateral deposited  with
such intermediary.
 
If  the price of the security sold short increases between the time of the short
sale and the time a Theme  Portfolio replaces the borrowed security, that  Theme
Portfolio  will  incur a  loss;  conversely, if  the  price declines,  the Theme
Portfolio will  realize  a  gain. Any  gain  will  be decreased,  and  any  loss
increased,  by the transaction costs associated with the transaction. Although a
Theme Portfolio's gain is  limited by the  price at which  it sold the  security
short, its potential loss theoretically is unlimited.
 
No  Theme Portfolio will make a short sale if, after giving effect to such sale,
the market value of the  securities sold short exceeds 25%  of the value of  its
total assets or the Theme Portfolio's aggregate short sales of the securities of
any one issuer exceed the lesser of 2% of the Theme Portfolio's net assets or 2%
of  the securities of any  class of the issuer.  Moreover, a Theme Portfolio may
engage in  short sales  only with  respect to  securities listed  on a  national
securities  exchange. A Theme  Portfolio may make short  sales "against the box"
without respect to such limitations. In this type of short sale, at the time  of
the  sale the  Theme Portfolio owns  the security it  has sold short  or has the
immediate and unconditional right to acquire at no additional cost the identical
security.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The use of options, futures  contracts and forward currency contracts  ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1)  Successful  use  of  most of  these  instruments  depends  upon the
    Sub-adviser's ability to  predict movements  of the  overall securities  and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-adviser is experienced in
    the  use of these instruments, there can be no assurance that any particular
    strategy adopted will succeed.
 
        (2) There  might  be  imperfect correlation,  or  even  no  correlation,
    between  price  movements  of  an  instrument  and  price  movements  of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge  increased by less  than the  decline in value  of the  hedged
    investment,  the  hedge  would  not  be fully  successful.  Such  a  lack of
    correlation might  occur  due to  factors  unrelated  to the  value  of  the
    investments  being hedged,  such as  speculative or  other pressures  on the
    markets in  which the  hedging instrument  is traded.  The effectiveness  of
    hedges  using hedging  instruments on indices  will depend on  the degree of
    correlation between price movements in the index and price movements in  the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or  partially offsetting the negative  effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by  offsetting the positive  effect of favorable  price
    movements  in  the hedged  investments. For  example,  if a  Theme Portfolio
    entered into a short  hedge because the Sub-adviser  projected a decline  in
    the price of a security in the Theme Portfolio's portfolio, and the price of
    that security increased instead, the gain from that increase might be wholly
    or  partially offset by  a decline in  the price of  the hedging instrument.
    Moreover, if the price of the  hedging instrument declined by more than  the
    increase  in the price of  the security, the Theme  Portfolio could suffer a
    loss. In either such case, the Theme  Portfolio would have been in a  better
    position had it not hedged at all.
 
        (4)  As  described  below,  the Theme  Portfolio  might  be  required to
    maintain assets  as "cover,"  maintain segregated  accounts or  make  margin
    payments  when it  takes positions  in instruments  involving obligations to
    third parties (I.E., instruments other than purchased options). If the Theme
    Portfolio were unable  to close out  its positions in  such instruments,  it
    might  be required to continue  to maintain such assets  or accounts or make
    such payments until the position expired or matured. The requirements  might
    impair the Theme Portfolio's ability to sell a portfolio security or make an
    investment  at a  time when  it would  otherwise be  favorable to  do so, or
    require  that  the  Theme   Portfolio  sell  a   portfolio  security  at   a
    disadvantageous  time. The Theme Portfolio's ability to close out a position
    in an instrument
 
                   Statement of Additional Information Page 8
<PAGE>
                             AIM GLOBAL THEME FUNDS
    prior to  expiration  or maturity  depends  on  the existence  of  a  liquid
    secondary  market  or, in  the absence  of  such a  market, the  ability and
    willingness of the other party to the transaction ("contra party") to  enter
    into  a  transaction  closing  out  the  position.  Therefore,  there  is no
    assurance that any position can  be closed out at a  time and price that  is
    favorable to the Theme Portfolio.
 
WRITING CALL OPTIONS
Each  Theme Portfolio may  write (sell) call options  on securities, indices and
currencies. Call options generally will be written on securities and  currencies
that, in the opinion of the Sub-adviser are not expected to make any major price
moves  in  the near  future  but that,  over  the long  term,  are deemed  to be
attractive investments for the Theme Portfolios.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
style) or on (European style) a certain  date (the expiration date). So long  as
the  obligation of  the writer  of a  call option  continues, he  or she  may be
assigned an exercise  notice, requiring  him or  her to  deliver the  underlying
security  or currency  against payment  of the  exercise price.  This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer  effects  a closing  purchase  transaction by  purchasing  an  option
identical to that previously sold.
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on the basis of investment considerations consistent with  each
Theme  Portfolio's investment  objective. When  writing a  call option,  a Theme
Portfolio, in return for the premium, gives up the opportunity for profit from a
price increase in the underlying security or currency above the exercise  price,
and  retains  the risk  of loss  should the  price of  the security  or currency
decline. Unlike one who owns securities or currencies not subject to an  option,
a  Theme Portfolio  has no  control over  when it  may be  required to  sell the
underlying securities or currencies, since most options may be exercised at  any
time  prior to the option's expiration. If  a call option that a Theme Portfolio
has written expires, the Theme  Portfolio will realize a  gain in the amount  of
the  premium; however, such gain may be offset  by a decline in the market value
of the underlying  security or currency  during the option  period. If the  call
option  is exercised, the Theme  Portfolio will realize a  gain or loss from the
sale of the underlying security or  currency, which will be increased or  offset
by  the premium received. Each  Theme Portfolio does not  consider a security or
currency covered by a call option to be  "pledged" as that term is used in  that
Theme Portfolio's policy that limits the pledging or mortgaging of its assets.
 
Writing  call options can serve as a limited short hedge because declines in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
appreciates to a price higher than the exercise price of the call option, it can
be expected that  the option will  be exercised  and a Theme  Portfolio will  be
obligated to sell the security or currency at less than its market value.
 
The  premium that a Theme Portfolio receives for writing a call option is deemed
to constitute the  market value of  an option. The  premium the Theme  Portfolio
will  receive from writing a  call option will reflect,  among other things, the
current market  price of  the  underlying investment,  the relationship  of  the
exercise  price to  such market  price, the  historical price  volatility of the
underlying investment,  and the  length  of the  option period.  In  determining
whether  a  particular  call  option should  be  written,  the  Sub-adviser will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing transactions  will  be effected  in  order to  realize  a profit  on  an
outstanding  call option,  to prevent  an underlying  security or  currency from
being called, or  to permit  the sale of  the underlying  security or  currency.
Furthermore,  effecting a closing  transaction will permit  a Theme Portfolio to
write another call option on the  underlying security or currency with either  a
different exercise price or expiration date, or both.
 
Each  Theme Portfolio will pay transaction  costs in connection with the writing
of options and in  entering into closing  purchase contracts. Transaction  costs
relating  to  options  activity are  normally  higher than  those  applicable to
purchases and sales of portfolio securities.
 
The exercise price of the  options may be below, equal  to or above the  current
market  values of the  underlying securities, indices or  currencies at the time
the options are written. From  time to time, a  Theme Portfolio may purchase  an
underlying  security or currency for delivery in accordance with the exercise of
an option, rather than delivering such security or currency from its  portfolio.
In such cases, additional costs will be incurred.
 
A  Theme  Portfolio  will realize  a  profit  or loss  from  a  closing purchase
transaction if the cost of the  transaction is less or more, respectively,  than
the  premium received from  writing the option. Because  increases in the market
price of a call option generally will  reflect increases in the market price  of
the   underlying   security   or   currency,  any   loss   resulting   from  the
 
                   Statement of Additional Information Page 9
<PAGE>
                             AIM GLOBAL THEME FUNDS
repurchase of a  call option  is likely  to be  offset in  whole or  in part  by
appreciation of the underlying security or currency owned by a Theme Portfolio.
 
WRITING PUT OPTIONS
Each   Theme  Portfolio  may  write  put  options  on  securities,  indices  and
currencies. A put option gives  the purchaser of the  option the right to  sell,
and  the  writer (seller)  the  obligation to  buy,  the underlying  security or
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style) the  expiration date.  The operation  of put  options in other
respects, including their related risks and rewards, is substantially  identical
to that of call options.
 
A  Theme Portfolio generally would write  put options in circumstances where the
Sub-adviser wishes to purchase the underlying  security or currency for a  Theme
Portfolio's  holdings at  a price  lower than  the current  market price  of the
security or currency. In such event, a Theme Portfolio would write a put  option
at  an  exercise price  that, reduced  by  the premium  received on  the option,
reflects the lower price it is willing  to pay. Since the Theme Portfolio  would
also  receive interest on debt securities  or currencies maintained to cover the
exercise price of the  option, this technique could  be used to enhance  current
return  during periods  of market  uncertainty. The  risk in  such a transaction
would be that  the market  price of the  underlying security  or currency  would
decline below the exercise price less the premium received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected that the put option will be exercised and a Theme Portfolio will be
obligated to purchase the security or currency at greater than its market value.
 
PURCHASING PUT OPTIONS
Each Theme  Portfolio  may  purchase  put options  on  securities,  indices  and
currencies.  As the  holder of a  put option,  a Theme Portfolio  would have the
right to sell the underlying security or  currency at the exercise price at  any
time  until (American style) or on (European style) the expiration date. A Theme
Portfolio may enter into closing sale transactions with respect to such options,
exercise such option or permit such option to expire.
 
Each Theme Portfolio  may purchase  a put option  on an  underlying security  or
currency  ("protective put")  owned by the  Theme Portfolio in  order to protect
against an anticipated decline  in the value of  the security or currency.  Such
hedge  protection is provided  only during the  life of the  put option when the
Theme Portfolio, as the holder of the put option, is able to sell the underlying
security or currency at the put exercise price regardless of any decline in  the
underlying  security's market  price or  currency's exchange  value. The premium
paid for  the put  option and  any  transaction costs  would reduce  any  profit
otherwise available for distribution when the security or currency is eventually
sold.
 
A  Theme Portfolio may also purchase put options  at a time when it does not own
the underlying security or currency. By purchasing put options on a security  or
currency  it does not own, that Theme  Portfolio seeks to benefit from a decline
in the market price of the underlying security or currency. If the put option is
not sold when it has remaining value, and if the market price of the  underlying
security  or currency remains equal to or greater than the exercise price during
the life of the put option, the Theme Portfolio will lose its entire  investment
in  the put option. In order for the  purchase of a put option to be profitable,
the  market  price  of  the   underlying  security  or  currency  must   decline
sufficiently  below  the exercise  price to  cover  the premium  and transaction
costs, unless the put option is sold in a closing sale transaction.
 
PURCHASING CALL OPTIONS
Each Theme  Portfolio  may purchase  call  options on  securities,  indices  and
currencies.  As the holder of a call  option, the Theme Portfolio would have the
right to purchase the underlying security  or currency at the exercise price  at
any  time until (American style)  or on (European style)  the expiration date. A
Theme Portfolio may enter  into closing sale transactions  with respect to  such
options, exercise such options or permit such options to expire.
 
Call  options may be purchased by a Theme Portfolio for the purpose of acquiring
the underlying security or currency for its portfolio. Utilized in this fashion,
the purchase  of call  options would  enable a  Theme Portfolio  to acquire  the
security  or currency at the exercise price  of the call option plus the premium
paid. At times,  the net  cost of  acquiring the  security or  currency in  this
manner may be less than the cost of acquiring the security or currency directly.
This  technique may also  be useful to  a Theme Portfolio  in purchasing a large
block of securities  that would be  more difficult to  acquire by direct  market
purchases.  So long as it  holds such a call  option, rather than the underlying
security or currency itself, the Theme Portfolio is partially protected from any
unexpected decline in the  market price of the  underlying security or  currency
and, in such event, could allow the call option to expire, incurring a loss only
to the extent of the premium paid for the option.
 
A  Theme Portfolio  may also purchase  call options on  underlying securities or
currencies it owns to avoid realizing losses that would result in a reduction of
its current return.  For example,  where a Theme  Portfolio has  written a  call
option on an
 
                  Statement of Additional Information Page 10
<PAGE>
                             AIM GLOBAL THEME FUNDS
underlying security or currency having a current market value below the price at
which  it purchased the  security or currency,  an increase in  the market price
could result in the exercise of the  call option written by the Theme  Portfolio
and  the  realization  of  a  loss  on  the  underlying  security  or  currency.
Accordingly, the  Theme Portfolio  could  purchase a  call  option on  the  same
underlying  security or currency, which could  be exercised to fulfill the Theme
Portfolio's delivery obligations under  its written call  (if it is  exercised).
This  strategy could  allow the Theme  Portfolio to avoid  selling the portfolio
security or currency  at a time  when it  has an unrealized  loss; however,  the
Theme  Portfolio would have  to pay a  premium to purchase  the call option plus
transaction costs.
 
Aggregate premiums paid  for put and  call options  will not exceed  5% of  each
Theme Portfolio's total assets at the time of each purchase.
 
A Theme Portfolio may attempt to accomplish objectives similar to those involved
in  using Forward Contracts, by purchasing put  or call options on currencies. A
put option  gives  the Theme  Portfolio  as purchaser  the  right (but  not  the
obligation)  to sell a specified amount of currency at the exercise price at any
time until (American style)  or on (European style)  the expiration date of  the
option.  A call option gives the Theme Portfolio as purchaser the right (but not
the obligation) to purchase a specified amount of currency at the exercise price
at any time until (American style) or on (European style) the expiration date of
the option. A Theme Portfolio might purchase a currency put option, for example,
to protect itself against a decline in  the dollar value of a currency in  which
it  holds  or anticipates  holding securities.  If  the currency's  value should
decline against the  dollar, the  loss in currency  value should  be offset,  in
whole  or in part, by an  increase in the value of the  put. If the value of the
currency instead should rise against the  dollar, any gain to a Theme  Portfolio
would  be reduced by the premium it had paid for the put option. A currency call
option might  be purchased,  for  example, in  anticipation  of, or  to  protect
against,  a rise in the value against the  dollar of a currency in which a Theme
Portfolio anticipates purchasing securities.
 
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing  corporation) and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates. A Theme Portfolio will not purchase an OTC option unless it believes that
daily valuations for  such options  are readily obtainable.  OTC options  differ
from  exchange-traded options  in that OTC  options are  transacted with dealers
directly and not through a clearing corporation (which guarantees  performance).
Consequently,  there  is  a risk  of  non-performance  by the  dealer.  Since no
exchange is involved, OTC options are valued  on the basis of an average of  the
last  bid prices obtained from dealers, unless  a quotation from only one dealer
is available, in which case only that  dealer's price will be used. In the  case
of  OTC options, there can  be no assurance that  a liquid secondary market will
exist for any particular option at any specific time.
 
   
The staff of the SEC considers purchased OTC options to be illiquid  securities.
A  Theme  Portfolio may  also  sell OTC  options  and, in  connection therewith,
segregate assets or cover its obligations with respect to OTC options written by
the Theme Portfolio. The assets used as cover for OTC options written by a Theme
Portfolio will  be  considered illiquid  unless  the  OTC options  are  sold  to
qualified  dealers who  agree that  the Theme  Portfolio may  repurchase any OTC
option it writes at a maximum price to  be calculated by a formula set forth  in
the  option  agreement. The  cover for  an  OTC option  written subject  to this
procedure would  be considered  illiquid only  to the  extent that  the  maximum
repurchase price under the formula exceeds the intrinsic value of the option.
    
 
A   Theme  Portfolio's  ability   to  establish  and   close  out  positions  in
exchange-listed options depends  on the existence  of a liquid  market. A  Theme
Portfolio  intends to purchase  or write only  those exchange-traded options for
which there appears to be  a liquid secondary market.  However, there can be  no
assurance  that  such  a  market  will exist  at  any  particular  time. Closing
transactions can be made for OTC  options only by negotiating directly with  the
contra  party or  by a transaction  in the  secondary market if  any such market
exists. Although a Theme Portfolio will enter into OTC options only with  contra
parties  that are expected  to be capable of  entering into closing transactions
with the Theme Portfolio, there is no assurance that the Theme Portfolio will in
fact be able to close out an OTC  option position at a favorable price prior  to
expiration.  In the event of insolvency of the contra party, the Theme Portfolio
might be unable to  close out an OTC  option position at any  time prior to  its
expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts  except that all settlements  are in cash and  gain or loss depends on
changes in the index in question (and thus on price movements in the  securities
market  or a particular market sector  generally) rather than on price movements
in individual securities or futures contracts.  When a Theme Portfolio writes  a
call on an index, it receives a premium and agrees that, prior to the expiration
date,  the purchaser of the  call, upon exercise of  the call, will receive from
the   Theme   Portfolio   an   amount    of   cash   if   the   closing    level
 
                  Statement of Additional Information Page 11
<PAGE>
                             AIM GLOBAL THEME FUNDS
of  the index upon which the call is based is greater than the exercise price of
the call. The  amount of cash  is equal  to the difference  between the  closing
price of the index and the exercise price of the call times a specified multiple
(the  "multiplier"), which determines  the total dollar value  for each point of
such difference. When  a Theme  Portfolio buys  a call on  an index,  it pays  a
premium  and has the same rights as to  such call as are indicated above. When a
Theme Portfolio buys a  put on an index,  it pays a premium  and has the  right,
prior  to the expiration date, to require the  seller of the put, upon the Theme
Portfolio's exercise of the put, to deliver to the Theme Portfolio an amount  of
cash  if the closing level of the index upon which the put is based is less than
the exercise  price of  the  put, which  amount of  cash  is determined  by  the
multiplier,  as described above for calls. When the Theme Portfolio writes a put
on an index, it receives a premium and the purchaser has the right, prior to the
expiration date, to require the  Theme Portfolio to deliver  to it an amount  of
cash  equal to  the difference between  the closing  level of the  index and the
exercise price  times the  multiplier, if  the closing  level is  less than  the
exercise price.
 
The  risks  of  investment in  index  options  may be  greater  than  options on
securities. Because index options  are settled in cash,  when a Theme  Portfolio
writes  a  call on  an  index it  cannot provide  in  advance for  its potential
settlement obligations by  acquiring and  holding the  underlying securities.  A
Theme  Portfolio can  offset some  of the  risk of  writing a  call index option
position by holding a  diversified portfolio of securities  similar to those  on
which  the underlying index  is based. However,  a Theme Portfolio  cannot, as a
practical matter,  acquire and  hold  a portfolio  containing exactly  the  same
securities  as underlie the index and, as a  result, bears a risk that the value
of the securities held will vary from the value of the index.
 
Even if a  Theme Portfolio could  assemble a securities  portfolio that  exactly
reproduced  the composition of the underlying index, it still would not be fully
covered from a risk standpoint because of the "timing risk" inherent in  writing
index  options. When an index  option is exercised, the  amount of cash that the
holder is  entitled to  receive  is determined  by  the difference  between  the
exercise  price  and the  closing index  level on  the date  when the  option is
exercised. As with  other kinds  of options, the  Theme Portfolio,  as the  call
writer,  will not know that it has been  assigned until the next business day at
the earliest. The time  lag between exercise and  notice of assignment poses  no
risk for the writer of a covered call on a specific underlying security, such as
common stock, because there the writer's obligation is to deliver the underlying
security,  not to pay its value  as of a fixed time in  the past. So long as the
writer already  owns the  underlying  security, it  can satisfy  its  settlement
obligations  by  simply delivering  it, and  the  risk that  its value  may have
declined since the exercise date is borne by the exercising holder. In contrast,
even if the  writer of an  index call  holds securities that  exactly match  the
composition  of  the  underlying index,  it  will  not be  able  to  satisfy its
assignment obligations by  delivering those  securities against  payment of  the
exercise  price. Instead, it will be required to  pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that  it
has  been assigned, the index may have declined, with a corresponding decline in
the value  of  its securities  portfolio.  This  "timing risk"  is  an  inherent
limitation  on the ability of index call writers to cover their risk exposure by
holding securities positions.
 
If a  Theme Portfolio  purchases an  index option  and exercises  it before  the
closing  index value for that day is available,  it runs the risk that the level
of the underlying  index may subsequently  change. If such  a change causes  the
exercised  option to fall out-of-the-money, the Theme Portfolio will be required
to pay the difference between the closing index value and the exercise price  of
the option (times the applicable multiplier) to the assigned writer.
 
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
Each Theme Portfolio may enter into interest rate or currency futures contracts,
and  may enter  into stock index  futures contracts  (collectively, "Futures" or
"Futures Contracts"),  as  a  hedge  against changes  in  prevailing  levels  of
interest  rates,  currency exchange  rates  or stock  price  levels in  order to
establish more definitely the effective return on securities or currencies  held
or  intended to be acquired by the  Theme Portfolio. A Theme Portfolio's hedging
may include  sales  of Futures  as  an offset  against  the effect  of  expected
increases  in interest rates, and decreases in currency exchange rates and stock
prices, and purchases  of Futures as  an offset against  the effect of  expected
declines  in interest rates,  and increases in currency  exchange rates or stock
prices.
 
Each Theme Portfolio only will enter  into Futures Contracts that are traded  on
futures  exchanges  and  are standardized  as  to maturity  date  and underlying
financial instrument. Futures exchanges and trading thereon in the United States
are regulated under the Commodity Exchange Act by the Commodity Futures  Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used  to reduce a Theme Portfolio's exposure to interest rate, currency exchange
rate and stock market  fluctuations, that Theme Portfolio  may be able to  hedge
its  exposure  more  effectively  and  at a  lower  cost  through  using Futures
Contracts.
 
                  Statement of Additional Information Page 12
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
A Futures Contract provides  for the future  sale by one  party and purchase  by
another party of a specified amount of a specific financial instrument (security
or currency) for a specified price at a designated date, time and place. A stock
index Futures Contract provides for the delivery, at a designated date, time and
place,  of  an amount  of  cash equal  to a  specified  dollar amount  times the
difference between the stock index value at the close of trading on the contract
and the price at  which the Futures Contract  is originally struck; no  physical
delivery  of stocks  comprising the index  is made. Brokerage  fees are incurred
when a  Futures  Contract  is  bought  or sold,  and  margin  deposits  must  be
maintained at all times the Futures Contract is outstanding.
 
Although  Futures Contracts typically require future delivery of and payment for
financial instruments or  currencies, Futures Contracts  usually are closed  out
before  the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering  into an offsetting Futures  Contract purchase or  sale,
respectively,   for  the  same  aggregate  amount  of  the  identical  financial
instrument or currency and  the same delivery date.  If the offsetting  purchase
price is less than the original sale price, the Theme Portfolio realizes a gain;
if  it  is  more,  the  Theme Portfolio  realizes  a  loss.  Conversely,  if the
offsetting sale  price is  more  than the  original  purchase price,  the  Theme
Portfolio  realizes a gain; if it is  less, the Theme Portfolio realizes a loss.
The transaction costs must also be included in these calculations. There can  be
no  assurance, however,  that a Theme  Portfolio will  be able to  enter into an
offsetting transaction  with  respect to  a  particular Futures  Contract  at  a
particular  time. If a Theme  Portfolio is not able  to enter into an offsetting
transaction, that Theme Portfolio will continue  to be required to maintain  the
margin deposits on the Futures Contract.
 
As  an example of an offsetting transaction, the contractual obligations arising
from the sale of one Futures Contract of September Deutschemarks on an  exchange
may  be fulfilled  at any  time before  delivery under  the Futures  Contract is
required (I.E., on a specified date  in September, the "delivery month") by  the
purchase  of another  Futures Contract  of September  Deutschemarks on  the same
exchange. In  such instance,  the  difference between  the  price at  which  the
Futures  Contract was sold and the price paid for the offsetting purchase, after
allowance for transaction  costs, represents  the profit  or loss  to the  Theme
Portfolio.
 
Each  Theme Portfolio's  Futures transactions will  be entered  into for hedging
purposes only; that  is, Futures  Contracts will be  sold to  protect against  a
decline in the price of securities or currencies that a Theme Portfolio owns, or
Futures  Contracts will  be purchased  to protect  a Theme  Portfolio against an
increase in the price of securities  or currencies it has committed to  purchase
or expects to purchase.
 
"Margin"  with respect to Futures Contracts is  the amount of funds that must be
deposited by a Theme Portfolio in order to initiate Futures trading and maintain
the Theme Portfolio's open positions in Futures Contracts. A margin deposit made
when the Futures  Contract is  entered into  ("initial margin")  is intended  to
ensure  the Theme Portfolio's performance under the Futures Contract. The margin
required for a particular Futures Contract is  set by the exchange on which  the
Futures  Contract is traded and may be  significantly modified from time to time
by the exchange during the term of the Futures Contract.
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission  merchant through which the Theme  Portfolio entered into the Futures
Contract will be made on a daily basis as the price of the underlying  security,
currency  or index fluctuates making the Futures Contract more or less valuable,
a process known as marking-to-market.
 
    RISKS OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts  are
volatile  and  are influenced  by, among  other  things, actual  and anticipated
changes in  interest rates  and currency  exchange rates,  and in  stock  market
movements,  which  in turn  are  affected by  fiscal  and monetary  policies and
national and international political and economic events.
 
There is a risk  of imperfect correlation between  changes in prices of  Futures
Contracts  and prices  of the  securities or  currencies in  a Theme Portfolio's
portfolio being hedged. The degree  of imperfection of correlation depends  upon
circumstances  such as variations  in speculative market  demand for Futures and
for securities or currencies, including technical influences in Futures trading;
and  differences  between  the  financial  instruments  being  hedged  and   the
instruments  underlying the standard Futures  Contracts available for trading. A
decision of whether, when and how to hedge involves skill and judgment, and even
a well-conceived hedge may be unsuccessful to some degree because of  unexpected
market behavior or interest or currency rate trends.
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
 
                  Statement of Additional Information Page 13
<PAGE>
                             AIM GLOBAL THEME FUNDS
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and options on  Futures Contracts prices during  a single trading  day.
The  daily limit  establishes the  maximum amount  that the  price of  a Futures
Contract or option may vary either up or down from the previous day's settlement
price at the end of a trading session. Once the daily limit has been reached  in
a  particular type of Futures Contract or option,  no trades may be made on that
day at a price beyond  that limit. The daily  limit governs only price  movement
during  a particular trading day and  therefore does not limit potential losses,
because the limit may prevent the liquidation of unfavorable positions.  Futures
Contract  and  option prices  have  occasionally moved  to  the daily  limit for
several consecutive trading days with  little or no trading, thereby  preventing
prompt  liquidation  of positions  and  subjecting some  traders  to substantial
losses.
 
If a Theme Portfolio  were unable to  liquidate a Futures  or option on  Futures
position  due to the absence  of a liquid secondary  market or the imposition of
price limits,  it could  incur  substantial losses.  The Theme  Portfolio  would
continue to be subject to market risk with respect to the position. In addition,
except  in the case of purchased options,  the Theme Portfolio would continue to
be required to  make daily variation  margin payments and  might be required  to
maintain  the position being hedged by the  Future or option or to maintain cash
or securities in a segregated account.
 
Certain characteristics  of the  Futures  market might  increase the  risk  that
movements  in the prices  of Futures Contracts  or options on  Futures might not
correlate perfectly  with  movements in  the  prices of  the  investments  being
hedged.  For example,  all participants  in the  Futures and  options on Futures
markets are subject to  daily variation margin calls  and might be compelled  to
liquidate  Futures  or  options on  Futures  positions whose  prices  are moving
unfavorably to avoid being  subject to further  calls. These liquidations  could
increase  price  volatility  of the  instruments  and distort  the  normal price
relationship between the Futures  or options and  the investments being  hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous  than  margin requirements  in the  securities  markets, there  might be
increased  participation   by  speculators   in   the  Futures   markets.   This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading"  and other  investment strategies  might result  in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options  on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the  premium paid,  to  assume a  position in  a  Futures Contract  (a  long
position if the option is a call and a short position if the option is a put) at
a  specified exercise price  at any time  during the period  of the option. Upon
exercise of the option, the  delivery of the Futures  position by the writer  of
the  option to the holder  of the option will be  accompanied by delivery of the
accumulated balance in the writer's Futures margin account, which represents the
amount by which the market price  of the Futures Contract, at exercise,  exceeds
(in  the case of  a call) or  is less than (in  the case of  a put) the exercise
price of the option on  the Futures Contract. If an  option is exercised on  the
last trading day prior to the expiration date of the option, the settlement will
be  made entirely in cash equal to  the difference between the exercise price of
the option and  the closing level  of the securities,  currencies or index  upon
which  the  Futures Contract  is  based on  the  expiration date.  Purchasers of
options who fail to exercise their options  prior to the exercise date suffer  a
loss of the premium paid.
 
The  purchase of  call options  on Futures can  serve as  a long  hedge, and the
purchase of put  options on Futures  can serve  as a short  hedge. Writing  call
options  on Futures can serve as a  limited short hedge, and writing put options
on Futures can serve as a limited  long hedge, using a strategy similar to  that
used for writing options on securities, foreign currencies or indices.
 
If a Theme Portfolio writes an option on a Futures Contract, it will be required
to  deposit initial  and variation  margin pursuant  to requirements  similar to
those applicable to Futures Contracts. Premiums received from the writing of  an
option on a Futures Contract are included in the initial margin deposit.
 
A  Theme Portfolio may seek to close out an option position by selling an option
covering the  same Futures  Contract  and having  the  same exercise  price  and
expiration  date.  The ability  to  establish and  close  out positions  on such
options is subject to the maintenance of a liquid secondary market.
 
LIMITATIONS ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS  ON
CURRENCIES
To  the extent that a Theme Portfolio  enters into Futures Contracts, options on
Futures Contracts, and options on foreign currencies traded on a  CFTC-regulated
exchange,  in each case other than for BONA FIDE hedging purposes (as defined by
the CFTC), the aggregate initial margin and premiums required to establish those
positions (excluding the amount  by which options  are "in-the-money") will  not
exceed  5% of the  liquidation value of  the Theme Portfolio,  after taking into

account unrealized  profits and  unrealized losses  on any  contracts the  Theme
Portfolio  has entered into. In general, a  call option on a Futures Contract is
"in-the-money" if  the value  of  the underlying  Futures Contract  exceeds  the
strike, I.E., exercise, price of the call; a put option on a Futures Contract is
"in-the-money"  if the value  of the underlying Futures  Contract is exceeded by
the strike price of the put. This guideline may be modified by the Trust's Board
of Trustees and  the Portfolio's  Board of  Trustees, as  applicable, without  a
shareholder  vote.  This limitation  does not  limit the  percentage of  a Theme
Portfolio's assets at risk to 5%.
    
 
FORWARD CONTRACTS
A Forward Contract is an obligation, usually arranged with a commercial bank  or
other  currency dealer, to purchase or  sell a currency against another currency
at a future  date and price  as agreed upon  by the parties.  A Theme  Portfolio
either  may  accept or  make delivery  of the  currency at  the maturity  of the
Forward Contract. A Theme Portfolio may  also, if its contra party agrees  prior
to  maturity, enter into a closing transaction involving the purchase or sale of
an offsetting contract.
 
A Theme Portfolio engages in  forward currency transactions in anticipation  of,
or  to protect itself against, fluctuations in exchange rates. A Theme Portfolio
might sell a  particular foreign currency  forward, for example,  when it  holds
bonds  denominated  in  a foreign  currency  but  anticipates, and  seeks  to be
protected against, a decline in the currency against the U.S. dollar. Similarly,
a Theme  Portfolio  might sell  the  U.S. dollar  forward  when it  holds  bonds
denominated  in U.S. dollars but anticipates, and seeks to be protected against,
a decline in  the U.S.  dollar relative to  other currencies.  Further, a  Theme
Portfolio might purchase a currency forward to "lock in" the price of securities
denominated in that currency that it anticipates purchasing.
 
   
Forward  Contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any stage  for  trades.  Each  Theme Portfolio  will  enter  into  such  Forward
Contracts with major U.S. or foreign banks and securities or currency dealers in
accordance  with guidelines approved by the  Trust's or the Portfolios' Board of
Trustees, as applicable.
    
 
A Theme  Portfolio may  enter  into Forward  Contracts  either with  respect  to
specific  transactions  or with  respect to  overall  investments of  that Theme
Portfolio. The precise matching of the Forward Contract amounts and the value of
specific securities generally will not be  possible because the future value  of
such  securities in  foreign currencies will  change as a  consequence of market
movements in the value of those securities between the date the Forward Contract
is entered into and the  date it matures. Accordingly,  it may be necessary  for
that  Theme Portfolio to purchase additional foreign currency on the spot (I.E.,
cash) market (and bear the expense of such purchase) if the market value of  the
security  is less  than the  amount of foreign  currency the  Theme Portfolio is
obligated to deliver and  if a decision  is made to sell  the security and  make
delivery of the foreign currency. Conversely, it may be necessary to sell on the
spot  market some of  the foreign currency  the Theme Portfolio  is obligated to
deliver. The projection  of short-term  currency market  movements is  extremely
difficult,  and the  successful execution  of a  short-term hedging  strategy is
highly uncertain. Forward Contracts involve  the risk that anticipated  currency
movements will not be predicted accurately, causing a Theme Portfolio to sustain
losses on these contracts and transaction costs.
 
At  or before the maturity of a  Forward Contract requiring a Theme Portfolio to
sell a currency, that  Theme Portfolio either  may sell a  security and use  the
sale proceeds to make delivery of the currency or retain the security and offset
its  contractual  obligation  to deliver  the  currency by  purchasing  a second
contract pursuant to which the Theme Portfolio will obtain, on the same maturity
date, the  same  amount  of  the  currency that  it  is  obligated  to  deliver.
Similarly,  a Theme Portfolio may  close out a Forward  Contract requiring it to
purchase a specified currency by entering into a second contract, if its  contra
party  agrees, entitling it to sell the same  amount of the same currency on the
maturity date of the first contract. A  Theme Portfolio would realize a gain  or
loss  as a  result of  entering into such  an offsetting  Forward Contract under
either circumstance  to  the extent  the  exchange  rate or  rates  between  the
currencies  involved moved between the execution dates of the first contract and
the offsetting contract.
 
The cost  to a  Theme Portfolio  of engaging  in Forward  Contracts varies  with
factors  such as the currencies involved, the  length of the contract period and
the market conditions  then prevailing.  Because Forward  Contracts are  usually
entered  into on a principal basis, no fees or commissions are involved. The use
of Forward  Contracts does  not  eliminate fluctuations  in  the prices  of  the
underlying  securities a Theme Portfolio owns or intends to acquire, but it does
establish a rate  of exchange in  advance. In addition,  while Forward  Contract
sales  limit  the risk  of loss  due to  a decline  in the  value of  the hedged
currencies, they also  limit any  potential gain  that might  result should  the
value of the currencies increase.

FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
A  Theme Portfolio  may use  options on  foreign currencies,  Futures on foreign
currencies, options on Futures  on foreign currencies  and Forward Contracts  to
hedge  against movements in  the values of  the foreign currencies  in which the
Theme Portfolio's securities are denominated.  Such currency hedges can  protect
against  price movements in a security that  the Theme Portfolio owns or intends
to acquire that  are attributable to  changes in  the value of  the currency  in
which  it is  denominated. Such  hedges do  not, however,  protect against price
movements in the securities that are attributable to other causes.
 
A Theme  Portfolio  might seek  to  hedge against  changes  in the  value  of  a
particular  currency  when  no  Futures  Contract,  Forward  Contract  or option
involving that currency is available or one of such contracts is more  expensive
than  certain  other contracts.  In such  cases, the  Theme Portfolio  may hedge
against price movements in that currency by entering into a contract on  another
currency  or basket of currencies, the  values of which the Sub-adviser believes
will have a positive correlation to the value of the currency being hedged.  The
risk  that movements in the  price of the contract  will not correlate perfectly
with movements in the price of the currency being hedged is magnified when  this
strategy is used.
 
The  value of Futures Contracts, options on Futures Contracts, Forward Contracts
and options  on  foreign currencies  depends  on  the value  of  the  underlying
currency  relative  to the  U.S. dollar.  Because foreign  currency transactions
occurring in the  interbank market  might involve  substantially larger  amounts
than  those  involved in  the  use of  Futures  Contracts, Forward  Contracts or
options, the Theme Portfolio  could be disadvantaged by  dealing in the odd  lot
market  (generally consisting of  transactions of less than  $1 million) for the
underlying foreign currencies at prices that  are less favorable than for  round
lots.
 
There is no systematic reporting of last sale information for foreign currencies
or  any  regulatory requirements  that quotations  available through  dealers or
other market sources be firm or revised on a timely basis. Quotation information
generally is representative of very  large transactions in the interbank  market
and  thus  might not  reflect  odd-lot transactions  where  rates might  be less
favorable.  The   interbank  market   in  foreign   currencies  is   a   global,
round-the-clock  market. To the  extent the U.S. options  or Futures markets are
closed while the markets for the underlying currencies remain open,  significant
price  and rate movements might take place in the underlying markets that cannot
be reflected in  the markets  for the Futures  contracts or  options until  they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies  might  be required  to  take place  within  the country  issuing the
underlying currency. Thus, the  Theme Portfolio might be  required to accept  or
make  delivery of the underlying foreign currency in accordance with any U.S. or
foreign regulations regarding the maintenance of foreign banking arrangements by
U.S. residents  and  might  be required  to  pay  any fees,  taxes  and  charges
associated with such delivery assessed in the issuing country.
 
COVER
Transactions  using Forward Contracts, Futures Contracts and options (other than
options purchased  by  a Theme  Portfolio)  expose  the Theme  Portfolio  to  an
obligation  to another  party. A  Theme Portfolio will  not enter  into any such
transactions unless it  owns either  (1) an offsetting  ("covered") position  in
securities,   currencies,  or  other  options,   Forward  Contracts  or  Futures
Contracts, or (2) cash, receivables and short-term debt securities with a  value
sufficient  at  all times  to  cover its  potential  obligations not  covered as
provided in (1)  above. Each  Theme Portfolio  will comply  with SEC  guidelines
regarding  cover for  these instruments and,  if the guidelines  so require, set
aside cash or liquid securities.
 
Assets used as cover or  held in a segregated account  cannot be sold while  the
position  in the corresponding  Forward Contract, Futures  Contract or option is
open, unless they are replaced with other appropriate assets. If a large portion
of a Theme Portfolio's assets is used for cover or otherwise set aside, it could
affect portfolio management or the Theme Portfolio's ability to meet  redemption
requests or other current obligations.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
Each  Theme  Portfolio  may invest  up  to 15%  of  its net  assets  in illiquid
securities. Securities may be  considered illiquid if  a Theme Portfolio  cannot
reasonably expect within seven days to sell the securities for approximately the
amount  at which  that Theme Portfolio  values such  securities. See "Investment
Limitations." The  sale of  illiquid securities,  if they  can be  sold at  all,
generally  will  require more  time and  result in  higher brokerage  charges or
dealer discounts  and  other selling  expenses  than  will the  sale  of  liquid
securities  such as securities eligible for trading on U.S. securities exchanges
or in OTC markets.  Moreover, restricted securities, which  may be illiquid  for
purposes  of  this limitation,  often sell,  if at  all, at  a price  lower than
similar securities that are not subject to restrictions on resale.
 
Illiquid securities include those that are subject to restrictions contained  in
the  securities laws  of other  countries. However,  securities that  are freely
marketable in the country  where they are principally  traded, but would not  be
freely  marketable in the United States,  will not be considered illiquid. Where
registration is required, a Theme Portfolio may be obligated to pay all or  part
of  the registration expenses  and a considerable period  may elapse between the
time of the decision to sell and  the time the Theme Portfolio may be  permitted
to  sell a security under an effective registration statement. If, during such a
period, adverse market  conditions were  to develop, the  Theme Portfolio  might
obtain a less favorable price than prevailed when it decided to sell.
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under the Securities Act of 1933, as amended ("1933 Act"), including
private placements, repurchase agreements, commercial paper, foreign  securities
and corporate bonds and notes. These instruments are often restricted securities
because  the  securities are  sold in  transactions not  requiring registration.
Institutional investors generally will not seek to sell these instruments to the
general  public,  but  instead  will   often  depend  either  on  an   efficient
institutional market in which such unregistered securities can be readily resold
or  on an issuer's ability to honor  a demand for repayment. Therefore, the fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the  1933 Act  for resales  of certain  securities to qualified
institutional buyers.  Institutional  markets  for  restricted  securities  have
developed  as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to  satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance  and  settlement of  unregistered securities  of domestic  and foreign
issuers, such as  the PORTAL  System sponsored  by the  National Association  of
Securities  Dealers,  Inc.  An insufficient  number  of  qualified institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a Theme Portfolio,  however, could  affect adversely the  marketability of  such
portfolio  securities and the Theme Portfolio might be unable to dispose of such
securities promptly or at favorable prices.
 
   
With  respect  to  liquidity  determinations  generally,  the  Trust's  or   the
Portfolios'  Board of Trustees,  as applicable, has  the ultimate responsibility
for determining  whether specific  securities, including  restricted  securities
pursuant to Rule 144A under the 1933 Act, are liquid or illiquid. Each Board has
delegated  the function of making day-to-day  determinations of liquidity to the
Sub-adviser,  in  accordance  with  procedures  approved  by  that  Board.   The
Sub-adviser  takes  into  account  a number  of  factors  in  reaching liquidity
decisions, including, but not  limited to, (i) the  frequency of trading in  the
security;  (ii) the number of  dealers that make quotes  for the security; (iii)
the number of dealers  that have undertaken  to make a  market in the  security;
(iv)  the  number of  other  potential purchasers;  and  (v) the  nature  of the
security and  how  trading  is effected  (e.g.,  the  time needed  to  sell  the
security,  how  offers  are  solicited  and  the  mechanics  of  transfer).  The
Sub-adviser monitors the liquidity  of securities held  by each Theme  Portfolio
and  periodically reports such determinations to  the Trust's or the Portfolios'
Board of Trustees, as applicable. If  the liquidity percentage restriction of  a
Theme  Portfolio is satisfied at the time of investment, a later increase in the
percentage of illiquid securities held by  the Theme Portfolio resulting from  a
change  in  market value  or  assets will  not  constitute a  violation  of that
restriction. If  as  a  result of  a  change  in market  value  or  assets,  the
percentage  of illiquid securities  held by the  Theme Portfolio increases above
the applicable limit, the Sub-adviser will  take appropriate steps to bring  the
aggregate amount of illiquid assets back within the

                             AIM GLOBAL THEME FUNDS
prescribed  limitations as soon  as reasonably practicable,  taking into account
the effect of any disposition on the Theme Portfolio.
 
FOREIGN SECURITIES
    POLITICAL, SOCIAL AND  ECONOMIC RISKS. Investing  in securities of  non-U.S.
companies may entail additional risks due to the potential political, social and
economic  instability  of  certain  countries and  the  risks  of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment convertibility of currencies into U.S. dollars and on repatriation of
capital  invested. In the event of  such expropriation, nationalization or other
confiscation by any country, a Theme Portfolio could lose its entire  investment
in any such country.
 
    RELIGIOUS,  POLITICAL AND ETHNIC  INSTABILITY. Certain countries  in which a
Theme Portfolio may invest  may have groups that  advocate radical religious  or
revolutionary  philosophies or  support ethnic independence.  Any disturbance on
the  part  of  such  individuals  could  carry  the  potential  for   widespread
destruction  or  confiscation  of  property owned  by  individuals  and entities
foreign to  such  country  and could  cause  the  loss of  a  Theme  Portfolio's
investment  in those  countries. Instability may  also result  from, among other
things: (i) authoritarian governments or  military involvement in political  and
economic    decision-making,   including    changes   in    government   through
extra-constitutional means;  (ii) popular  unrest  associated with  demands  for
improved  political, economic and social conditions; and (iii) hostile relations
with neighboring  or  other  countries.  Such  political,  social  and  economic
instability  could  disrupt the  principal financial  markets  in which  a Theme
Portfolio invests and adversely affect the value of a Theme Portfolio's assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity  markets, by  foreign entities  such as  a Theme  Portfolio.  These
restrictions  or controls may  at times limit or  preclude investment in certain
securities and may  increase the  cost and expenses  of a  Theme Portfolio.  For
example,   certain   countries  require   prior  governmental   approval  before
investments by  foreign  persons  may  be  made, or  may  limit  the  amount  of
investment by foreign persons in a particular company or limit the investment by
foreign  persons to only  a specific class  of securities of  a company that may
have less  advantageous  terms than  securities  of the  company  available  for
purchase  by nationals. Moreover, the national policies of certain countries may
restrict investment opportunities in issuers  or industries deemed sensitive  to
national  interests. In  addition, some countries  require governmental approval
for the repatriation of investment income, capital or the proceeds of securities
sales by  foreign investors.  In addition,  if  there is  a deterioration  in  a
country's  balance  of  payments or  for  other  reasons, a  country  may impose
restrictions on foreign capital remittances  abroad. A Theme Portfolio could  be
adversely   affected  by  delays  in,  or  a  refusal  to  grant,  any  required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting principles. Most of the  foreign securities held by a  Theme
Portfolio  will not  be registered  with the  SEC or  regulators of  any foreign
country, nor  will  the  issuers  thereof be  subject  to  the  SEC's  reporting
requirements.  Thus, there  will be  less available  information concerning most
foreign issuers  of securities  held  by a  Theme  Portfolio than  is  available
concerning  U.S.  issuers. In  instances where  the  financial statements  of an
issuer are  not deemed  to reflect  accurately the  financial situation  of  the
issuer,  the Sub-adviser  will take appropriate  steps to  evaluate the proposed
investment, which may include on-site inspection of the issuer, interviews  with
its   management  and   consultations  with   accountants,  bankers   and  other
specialists. There is  substantially less publicly  available information  about
foreign  companies  than  there are  reports  and ratings  published  about U.S.
companies and  the U.S.  government. In  addition, where  public information  is
available, it may be less reliable than such information regarding U.S. issuers.
Issuers  of securities in foreign jurisdictions are generally not subject to the
same degree of regulation as  are U.S. issuers with  respect to such matters  as
restrictions  on market  manipulation, insider trading  rules, shareholder proxy
requirements and timely disclosure of information.
 
    CURRENCY  FLUCTUATIONS.   Because  each   Theme  Portfolio,   under   normal
circumstances,  will invest  a substantial  portion of  its total  assets in the
securities of foreign issuers which  are denominated in foreign currencies,  the
strength  or weakness  of the U.S.  dollar against such  foreign currencies will
account for part of a Theme Portfolio's investment performance. A decline in the
value of any particular currency against the U.S. dollar will cause a decline in
the U.S. dollar value of that Theme Portfolio's holdings of securities and  cash
denominated  in such currency  and, therefore, will cause  an overall decline in
the appropriate Fund's net asset value and any net investment income and capital
gains derived  from  such  securities  to be  distributed  in  U.S.  dollars  to
shareholders  of that Fund. Moreover, if the  value of the foreign currencies in
 
                  Statement of Additional Information Page 18
<PAGE>
                             AIM GLOBAL THEME FUNDS
which a Theme Portfolio  receives its income falls  relative to the U.S.  dollar
between  receipt of the income and  the making of Theme Portfolio distributions,
the Theme Portfolio  may be required  to liquidate securities  in order to  make
distributions  if the Theme  Portfolio has insufficient cash  in U.S. dollars to
meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors, including the supply  and demand for particular currencies,
central bank efforts to support particular currencies, the relative movement  of
interest  rates and the pace of business activity in the other countries and the
United States, and other economic  and financial conditions affecting the  world
economy.
 
Although  each Theme Portfolio values its assets daily in terms of U.S. dollars,
the Portfolios do  not intend to  convert their holdings  of foreign  currencies
into  U.S. dollars  on a daily  basis. Each Portfolio  will do so,  from time to
time, and  investors  should be  aware  of  the costs  of  currency  conversion.
Although  foreign exchange dealers do  not charge a fee  for conversion, they do
realize a profit based on the difference ("spread") between the prices at  which
they buy and sell various currencies. Thus, a dealer may offer to sell a foreign
currency  to a Portfolio at  one rate, while offering  a lesser rate of exchange
should a Portfolio desire to sell that currency to the dealer.
 
    ADVERSE MARKET CHARACTERISTICS.  Securities of many  foreign issuers may  be
less  liquid and their  prices more volatile than  securities of comparable U.S.
issuers. In  addition,  foreign securities  markets  and brokers  generally  are
subject  to  less governmental  supervision and  regulation  than in  the United
States, and  foreign  securities  transactions  usually  are  subject  to  fixed
commissions,  which  generally are  higher than  negotiated commissions  on U.S.
transactions. In addition,  foreign securities  transactions may  be subject  to
difficulties  associated  with the  settlement of  such transactions.  Delays in
settlement could result in  temporary periods when assets  of a Theme  Portfolio
are  uninvested  and no  return  is earned  thereon.  The inability  of  a Theme
Portfolio to make intended security  purchases due to settlement problems  could
cause   that  Theme  Portfolio  to  miss  attractive  investment  opportunities.
Inability to dispose of a portfolio  security due to settlement problems  either
could  result in losses  to that Theme  Portfolio due to  subsequent declines in
value of the portfolio security or, if  that Theme Portfolio has entered into  a
contract  to  sell  the security,  could  result  in possible  liability  to the
purchaser. The Sub-adviser will consider such difficulties when determining  the
allocation  of a  Theme Portfolio's  assets, although  the Sub-adviser  does not
believe that such difficulties  will have a material  adverse effect on a  Theme
Portfolio's portfolio trading activities.
 
Each  Theme Portfolio  may use  foreign custodians,  which may  involve risks in
addition to those  related to  its use of  U.S. custodians.  Such risks  include
uncertainties  relating to  determining and  monitoring the  foreign custodian's
financial strength, reputation and standing; maintaining appropriate  safeguards
concerning  that  Theme Portfolio's  investments;  and possible  difficulties in
obtaining and enforcing judgments against such custodians.
 
    WITHHOLDING TAXES. Each Theme Portfolio's net investment income from foreign
issuers may be  subject to withholding  taxes by the  foreign issuer's  country,
thereby  reducing that income or delaying the receipt of income when those taxes
may be recaptured. See "Taxes."
 
    CONCENTRATION. To the extent a Theme Portfolio invests a significant portion
of its assets in securities of issuers located in a particular country or region
of the world, such Portfolio may be subject to greater risks and may  experience
greater volatility than a fund that is more broadly diversified geographically.
 
    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Belgium,
Denmark,  France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg, Netherlands,
Portugal, Spain, and the United  Kingdom) eliminated certain import tariffs  and
quotas  and  other trade  barriers with  respect  to one  another over  the past
several years. The  Sub-adviser believes that  this deregulation should  improve
the  prospects for  economic growth  in many  Western European  countries. Among
other things, the deregulation could  enable companies domiciled in one  country
to  avail  themselves  of lower  labor  costs  existing in  other  countries. In
addition, this deregulation could benefit companies domiciled in one country  by
opening  additional markets  for their  goods and  services in  other countries.
Since, however, it is not  clear what the exact form  or effect of these  Common
Market  reforms  will be  on business  in  Western Europe,  it is  impossible to
predict the long-term  impact of  the implementation  of these  programs on  the
securities owned by a Theme Portfolio.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN COUNTRIES.
Investing in Russia  and Eastern European  countries involves a  high degree  of
risk  and special considerations not typically  associated with investing in the
United States securities markets, and  should be considered highly  speculative.
Such  risks include: (1)  delays in settling portfolio  transactions and risk of
loss arising out of the system of  share registration and custody; (2) the  risk
that  it may be impossible  or more difficult than  in other countries to obtain
and/or enforce a  judgement; (3) pervasiveness  of corruption and  crime in  the
economic system; (4) currency exchange rate volatility and the lack of available
currency hedging

instruments;  (5) higher rates of inflation (including the risk of social unrest
associated with periods of hyper-inflation) and high unemployment; (6)  controls
on  foreign  investment and  local practices  disfavoring foreign  investors and
limitations on repatriation of invested capital, profits and dividends, and on a
fund's ability  to exchange  local currencies  for U.S.  dollars; (7)  political
instability and social unrest and violence; (8) the risk that the governments of
Russia  and Eastern European countries may decide not to continue to support the
economic  reform  programs  implemented  recently  and  could  follow  radically
different  political  and/or economic  policies to  the detriment  of investors,
including non-market-oriented policies such as the support of certain industries
at the expense  of other  sectors or  investors, or  a return  to the  centrally
planned  economy  that  existed when  such  countries  had a  communist  form of
government; (9)  the  financial  condition  of  companies  in  these  countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of  international trade; (11)  the risk that  the tax system  in these countries
will not  be reformed  to prevent  inconsistent, retroactive  and/or  exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly  since 1990. The general government position has deteriorated as a
result of weakening economic  growth and stimulative  measures taken to  support
economic  activity and to  restore financial stability.  Although the decline in
interest  rates  and  fiscal  stimulation   packages  have  helped  to   contain
recessionary  forces, uncertainties remain. Japan is also heavily dependent upon
international trade, so its  economy is especially  sensitive to trade  barriers
and  disputes.  Japan has  had difficult  relations  with its  trading partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible that  trade sanctions  and other  protectionist measures  could  impact
Japan adversely in both the short and the long term.
 
The  common  stocks  of many  Japanese  companies trade  at  high price-earnings
ratios. Differences  in accounting  methods  make it  difficult to  compare  the
earnings  of  Japanese companies  with those  of  companies in  other countries,
especially in the  U.S. In  general, however, reported  net income  in Japan  is
understated  relative to  U.S. accounting standards  and this is  one reason why
price-earnings  ratios  of  the  stocks   of  Japanese  companies  have   tended
historically  to be  higher than  those for  U.S. stocks.  In addition, Japanese
companies have  tended to  have  higher growth  rates  than U.S.  companies  and
Japanese  interest rates  have generally  been lower than  in the  U.S., both of
which factors tend to result in  lower discount rates and higher  price-earnings
ratios in Japan than in the U.S.
 
The  Japanese securities  markets are  less regulated  than those  in the United
States. Evidence has emerged from time to time of distortion of market prices to
serve political or other purposes.  Shareholders' rights are not always  equally
enforced.  In addition, Japan's banking  industry is undergoing problems related
to bad loans and declining values in real estate.
 
    SPECIAL CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of  the
risks  associated with international investments  are heightened for investments
in Pacific region  countries. For  example, some  of the  currencies of  Pacific
region  countries  have experienced  steady  devaluations relative  to  the U.S.
dollar, and major  adjustments have been  made periodically in  certain of  such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional  disputes  also exist  between South  Korea  and North  Korea. In
addition, the  Theme Portfolios  may  invest in  Hong  Kong, which  reverted  to
Chinese  Administration on July 1, 1997. Investments in Hong Kong may be subject
to expropriation, national,  nationalization or  confiscation, in  which case  a
Theme  Portfolio could lose its entire investment in Hong Kong. In addition, the
reversion of Hong Kong also  presents a risk that the  Hong Kong dollar will  be
devalued  and a  risk of  possible loss  of investor  confidence in  Hong Kong's
currency, stock market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American  countries have experienced substantial,  and in some periods extremely
high, rates of  inflation for many  years. Inflation and  rapid fluctuations  in
inflation  rates have had and may continue  to have very negative effects on the
economies and securities  markets of certain  Latin American countries.  Certain
Latin  American countries are also among the largest debtors to commercial banks
and foreign governments. At times certain Latin American countries have declared
moratoria on  the payment  of principal  and/or interest  on external  debt.  In
addition,  certain  Latin  American  securities  markets  have  experienced high
volatility in recent years.
 
Latin American countries may  also close certain sectors  of their economies  to
equity  investments  by foreigners.  Further due  to  the absence  of securities
markets and  publicly  owned corporations  and  due to  restrictions  on  direct
investment  by foreign entities,  investments may only be  made in certain Latin
American  countries  solely   or  primarily   through  governmentally   approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at  artificial levels to the U.S. dollar rather than at levels determined by the
market. This type  of system can  lead to  sudden and large  adjustments in  the
 
                  Statement of Additional Information Page 20

                             AIM GLOBAL THEME FUNDS
currency  which, in turn, can  have a disruptive and  negative effect on foreign
investors. For example, in late  1994, the value of  the Mexican peso lost  more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL   CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in  the
securities of companies in emerging markets may entail special risks relating to
potential political and  economic instability  and the  risks of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment, convertibility of currencies into  U.S. dollars and on  repatriation
of  capital invested.  In the  event of  such expropriation,  nationalization or
other confiscation  by any  country, a  Theme Portfolio  could lose  its  entire
investment in any such country.
 
Emerging  securities  markets are  substantially  smaller, less  developed, less
liquid and more volatile than the major securities markets. The limited size  of
emerging securities markets and limited trading value in issuers compared to the
volume  of  trading in  U.S. securities  could  cause prices  to be  erratic for
reasons apart  from factors  that  affect the  quality  of the  securities.  For
example, limited market size may cause prices to be unduly influenced by traders
who  control  large  positions. Adverse  publicity  and  investors' perceptions,
whether or  not  based on  fundamental  analysis,  may decrease  the  value  and
liquidity  of portfolio  securities, especially  in these  markets. In addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience of financial intermediaries, a lack of modern technology, the  lack
of  a sufficient capital base to expand business operations, and the possibility
of permanent or temporary termination of trading.
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in more developed markets.  In such emerging securities there may
be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economies  and securities
markets of certain emerging market countries.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
FEEDER FUNDS
The Financial Services  Fund, Infrastructure Fund,  Resources Fund and  Consumer
Products  and Services Fund each has the following fundamental investment policy
to enable  it to  invest  in the  Financial Services  Portfolio,  Infrastructure
Portfolio,  Resources Portfolio  and Consumer  Products and  Services Portfolio,
respectively:
 
Notwithstanding any other investment policy of the Fund, the Fund may invest all
of  its  investable  assets  (cash,   securities  and  receivables  related   to
securities)  in an  open-end management investment  company having substantially
the same investment objective, policies and limitations as the Fund.
 
   
All other fundamental  investment policies, and  the non-fundamental  investment
policies,  of each  Feeder Fund and  its corresponding  Portfolio are identical.
Therefore, although  the following  discusses the  investment policies  of  each
Portfolio  and its Board of Trustees, it applies equally to each Feeder Fund and
its Board of Trustees.
    
 
   
Each Portfolio has adopted the  following investment limitations as  fundamental
policies  that (unless otherwise  noted) may not be  changed without approval by
the affirmative vote of a majority  of the outstanding shares of the  Portfolio.
Whenever  a  Feeder Fund  is requested  to vote  on a  change in  the investment
limitations of its corresponding Portfolio, the Fund will hold a meeting of  its
shareholders and will cast its votes as instructed by its shareholders.
    
 
No Portfolio may:
 
        (1)  Purchase or sell real estate, except that investments in securities
    of issuers that  invest in  real estate and  investments in  mortgage-backed
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    the  Portfolio  may  exercise  rights  under  agreements  relating  to  such
    securities,  including the right  to enforce security  interests and to hold
    real estate acquired by  reason of such enforcement  until that real  estate
    can be liquidated in an orderly manner;

    currency contracts,  swap  transactions  and other  financial  contracts  or
    derivative instruments;
 
        (3)  Engage in the business of underwriting securities of other issuers,
    except to the extent that the  Portfolio might be considered an  underwriter
    under  the federal  securities laws  in connection  with its  disposition of
    portfolio securities;
 
        (4) Make loans, except through loans of portfolio securities or  through
    repurchase  agreements, provided that  for purposes of  this limitation, the
    acquisition of bonds, debentures, other  debt securities or instruments,  or
    participations  or  other interests  therein  and investments  in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (5) Issue senior securities or  borrow money, except as permitted  under
    the  1940 Act  and then not  in excess of  33 1/3% of  the Portfolio's total
    assets (including the  amount borrowed  but reduced by  any liabilities  not
    constituting  borrowings)  at the  time of  the  borrowing, except  that the
    Portfolio may  borrow  up to  an  additional 5%  of  its total  assets  (not
    including the amount borrowed) for temporary or emergency purposes; or
 
        (6)  Purchase securities of any one issuer if, as a result, more than 5%
    of the Portfolio's  total assets  would be  invested in  securities of  that
    issuer  or the Portfolio would own or  hold more than 10% of the outstanding
    voting securities of that issuer, except  that up to 25% of the  Portfolio's
    total  assets may be invested without  regard to this limitation, and except
    that this limitation does  not apply to securities  issued or guaranteed  by
    the  U.S.  government, its  agencies or  instrumentalities or  to securities
    issued by other investment companies.
 
The following investment policies of each Portfolio are not fundamental policies
and may  be  changed  by vote  of  the  Portfolios' Board  of  Trustees  without
shareholder approval. No Portfolio may:
 
        (1)  Invest in securities of an issuer if the investment would cause the
    Portfolio to own more than 10% of any class of securities of any one issuer;
 
        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;
 
        (3)  Invest  more than  15% of  its net  assets in  illiquid securities,

    an  option on foreign currency traded  on a CFTC-regulated exchange, in each
    case other than for BONA FIDE hedging purposes (as defined by the CFTC),  if
    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5%  of the liquidation value of the Portfolio's portfolio, after taking into
    account unrealized  profits  and  unrealized losses  on  any  contracts  the
    Portfolio has entered into;
 
        (5)  Borrow money except for temporary or emergency purposes (other than
    to meet redemptions). While  borrowings exceed 5%  of the Portfolio's  total
    assets, the Portfolio will not make any additional investments;
 
        (6)  Invest  more  than 10%  of  its  total assets  in  shares  of other
    investment companies and may not invest more than 5% of its total assets  in
    any one investment company or acquire more than 3% of the outstanding voting
    securities of any one investment company;
 
        (7)  Purchase  securities on  margin, provided  that each  Portfolio may
    obtain short-term credits as may be necessary for the clearance of purchases
    and sales of securities,  and further provided that  the Portfolio may  make
    margin deposits in connection with its use of financial options and futures,
    forward  and spot currency contracts,  swap transactions and other financial
    contracts or derivative instruments; or
 
        (8) Mortgage, pledge, or  hypothecate any of  its assets, provided  that
    this  shall not apply to  the transfer of securities  in connection with any
    permissible borrowing  or  to  collateral arrangements  in  connection  with
    permissible activities.
 
Investors should refer to the Prospectus for further information with respect to
the  investment objective of each Feeder Fund,  which may not be changed without
the approval of Fund shareholders, and its corresponding Portfolio's  investment
objective,  which may be  changed without the approval  of its shareholders, and
other investment policies, techniques and limitations,  which may or may not  be
changed without shareholder approval.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject to policies  established by  the Trust's  and the  Portfolios' Board  of
Trustees,  the  Sub-adviser  is  responsible for  the  execution  of  each Theme
Portfolio's securities  transactions and  the  selection of  broker/dealers  who
execute  such  transactions  on behalf  of  each Theme  Portfolio.  In executing
transactions, the  Sub-adviser  seeks  the  best  net  results  for  each  Theme
Portfolio,  taking  into  account  such  factors  as  the  price  (including the
applicable brokerage commission or dealer spread), size of the order, difficulty
of execution  and operational  facilities  of the  firm involved.  Although  the
Sub-adviser generally seeks reasonably competitive commission rates and spreads,
payment  of the lowest  commission or spread is  not necessarily consistent with
the best  net results.  While each  Theme Portfolio  may engage  in soft  dollar
arrangements  for research services, as described below, it has no obligation to
deal with  any broker/dealer  or group  of broker/dealers  in the  execution  of
portfolio transactions.
    
 
Consistent  with  the interests  of each  Theme  Portfolio, the  Sub-adviser may
select broker/dealers to execute that Theme Portfolio's portfolio transaction on
the basis of the research and brokerage services they provide to the Sub-adviser
for its use in  managing that Theme Portfolio  and its other advisory  accounts.
Such   services  may  include  furnishing   analyses,  reports  and  information
concerning issuers, industries, securities, geographic regions, economic factors
and trends,  portfolio  strategy, and  performance  of accounts;  and  effecting
securities  transactions and  performing functions  incidental thereto  (such as
clearance and settlement).  Research and brokerage  services received from  such
broker  are in  addition to,  and not in  lieu of,  the services  required to be
performed by  the Sub-adviser  under the  applicable investment  management  and
administration  contract. A  commission paid to  such broker may  be higher than
that which another qualified  broker would have charged  for effecting the  same
transaction,  provided that the  Sub-adviser determines in  good faith that such
commission is reasonable in terms either  of that particular transaction or  the
overall  responsibility of the Sub-adviser to  the Theme Portfolio and its other
clients and that  the total  commissions paid by  that Theme  Portfolio will  be
reasonable  in relation to the benefits it received over the long term. Research
services may also be received from dealers who execute portfolio transactions in
OTC markets.

The Sub-adviser may allocate brokerage  transactions to broker/dealers who  have
entered  into arrangements under which the  broker/dealer allocates a portion of
the commissions paid by a Theme  Portfolio toward payment of its expenses,  such
as custodian fees.
 
Investment  decisions for  a Theme Portfolio  and for  other investment accounts
managed by the  Sub-adviser are  made independently of  each other  in light  of
differing  conditions. However, the same investment decision occasionally may be
made for two  or more of  such accounts,  including a Theme  Portfolio. In  such
cases,  simultaneous  transactions  may  occur.  Purchases  or  sales  are  then
allocated as to price  or amount in  a manner deemed fair  and equitable to  all
accounts  involved. While in  some cases this practice  could have a detrimental
effect upon the price or  value of the security as  far as a Theme Portfolio  is
concerned,  in other  cases the Sub-adviser  believes that  coordination and the
ability to participate in volume transactions  will be beneficial to that  Theme
Portfolio.
 
   
Under a policy adopted by the Trust's and the Portfolios' Board of Trustees, and
subject  to the policy  of obtaining the  best net results,  the Sub-adviser may
consider a broker/dealer's sale of the shares  of the Theme Funds and the  other
portfolios  for which  AIM or  the Sub-adviser  serves as  investment manager or
administrator  in  selecting  broker/dealers  for  the  execution  of  portfolio
transactions.  This  policy does  not imply  a  commitment to  execute portfolio
transactions through all broker/dealers that sell shares of the Theme Funds  and
such other portfolios.
    
 
Each  Theme Portfolio contemplates purchasing  most foreign equity securities in
OTC markets or stock exchanges located in the countries in which the  respective
principal  offices of the issuers of the various securities are located, if that
is the best available market. The fixed commissions paid in connection with most
such foreign stock transactions generally are higher than negotiated commissions
on U.S.  transactions.  There  generally  is  less  government  supervision  and
regulation  of foreign  stock exchanges and  brokers than in  the United States.
Foreign security settlements  may in  some instances  be subject  to delays  and
related administrative uncertainties.
 
Foreign  equity securities may be held by a Theme Portfolio in the form of ADRs,
ADSs, EDRs, CDRs or securities convertible into foreign equity securities. ADRs,
ADSs, EDRs and  CDRs may  be listed  on stock exchanges,  or traded  in the  OTC
markets  in the United  States or Europe, as  the case may  be. ADRs, like other
securities traded in the United States, will be subject to negotiated commission
rates. The foreign and domestic debt securities and money market instruments  in
which a Theme Portfolio may invest are generally traded in the OTC markets.
 
   
A Theme Portfolio does not have any obligation to deal with any broker/dealer or
group  of broker/dealers in the execution of securities transactions. Each Theme
Portfolio contemplates that, consistent  with the policy  of obtaining the  best
net  results, brokerage transactions may  be conducted through certain companies
that are affiliated with AIM or the Sub-adviser. The Trust's or the  Portfolios'
Board of Trustees, as applicable, has adopted procedures in conformity with Rule
17e-1  under the 1940 Act to ensure  that all brokerage commissions paid to such
affiliates are reasonable and fair  in the context of  the market in which  they
are  operating. Any such transactions will  be effected and related compensation
paid only in accordance with applicable SEC regulations.
    
 
   
For the fiscal years ended October 31, 1997, 1996 and 1995, the Health Care Fund
paid aggregate  brokerage commissions  of $1,150,118,  $1,619,500 and  $545,743,
respectively.  For the fiscal years  ended October 31, 1997,  1996 and 1995, the
Telecommunications Fund  paid  aggregate brokerage  commissions  of  $2,254,069,
$2,848,733  and $2,253,982, respectively. For the fiscal years ended October 31,
1997, 1996 and 1995, the  Financial Services Portfolio paid aggregate  brokerage
commissions of $250,893, $77,822 and $38,814, respectively. For the fiscal years
ended  October  31,  1997,  1996 and  1995,  the  Infrastructure  Portfolio paid

respectively.  For the fiscal years  ended October 31, 1997,  1996 and 1995, the
Resources Portfolio paid aggregate brokerage commissions of $1,281,212, $496,370
and $98,462, respectively. For the fiscal years ended October 31, 1997, 1996 and
for the fiscal period December 30, 1994 (commencement of operations) to  October
31,  1995, the Consumer Products and Services Portfolio paid aggregate brokerage
commissions of $1,454,348,  $356,459 and $17,605,  respectively. For the  fiscal
years  ended October 31, 1997 and 1996, the Health Care Fund paid to LGT Bank in
Liechtenstein  AG,  which  was  an  "affiliated"  broker,  aggregate   brokerage
commissions  of $23,081  and $32,898,  respectively, for  transactions involving
purchases and sales of portfolio  securities which represented 2.01% and  2.03%,
respectively of the total brokerage commissions paid by the Health Care Fund and
1.61%  and 1.71%, respectively,  of the aggregate  dollar amount of transactions
involving payment of commissions by the Health Care Fund. For fiscal year  ended
October 31, 1997, the Telecommunications Fund paid to LGT Bank in Liechtenstein,
AG,  which  was  an  "affiliated"  broker,  aggregate  brokerage  commissions of
$220,584 for transactions involving purchases and sales of portfolio  securities
which  represented 1.00% of the total brokerage commissions paid by the Fund and
 .67% of  the  aggregate  dollar  amount of  transactions  involving  payment  of
commissions by the Fund.

PORTFOLIO TRADING AND TURNOVER
Although  each Theme Portfolio does not intend generally to trade for short-term
profits, the  securities held  by that  Theme Portfolio  will be  sold  whenever
management  believes it is appropriate to do so, without regard to the length of
time a  particular security  may  have been  held.  Portfolio turnover  rate  is
calculated  by dividing the lesser of sales or purchases of portfolio securities
by  each  Theme  Portfolio's   average  month-end  portfolio  value,   excluding
short-term  investments.  The portfolio  turnover rate  will  not be  a limiting
factor when  management deems  portfolio changes  appropriate. Higher  portfolio
turnover  involves  correspondingly  greater  brokerage  commissions  and  other
transaction costs that the Theme Portfolio will bear directly, and may result in
the realization of net capital gains  that are taxable when distributed to  each
Fund's  shareholders. For the fiscal years ended  October 31, 1996 and 1997, the
Telecommunications  Fund's   portfolio  turnover   rates  were   37%  and   35%,
respectively.  For the fiscal years ended October  31, 1996 and 1997, the Health
Care Fund's portfolio turnover rates were  157% and 149%, respectively. For  the
fiscal  years ended October 31, 1996 and  1997, the portfolio turnover rates for
the  Financial  Services  Portfolio,  Infrastructure  Portfolio  and   Resources
Portfolio  were 103% and 91%,  41% and 41%, and  94% and 321%, respectively. For
the fiscal years ended October 31,  1996 and 1997, the portfolio turnover  rates
for   the  Consumer  Products  and  Services   Portfolio  were  169%  and  392%,
respectively.

The  Board of Trustees has  a Nominating and Audit  Committee, comprised of Miss
Quigley and Messrs.  Anderson, Bayley  and Patterson, which  is responsible  for
nominating  persons to serve as Directors, reviewing audits of the Trust and its
funds and recommending firms to serve as independent auditors of the Trust. Each
of the Trustees  and Officers of  the Trust is  also a Director  or Trustee  and
Officer  of AIM Investment Portfolios, Inc.,  AIM Floating Rate Fund, AIM Series
Trust, AIM Growth Series, AIM Eastern Europe Fund, GT Global Variable Investment
Trust, GT Global  Variable Investment  Series, Global  Investment Portfolio  (of
which  the Portfolios are subtrusts),  Growth Portfolio, Floating Rate Portfolio

advised by AIM and sub-advised by  the Sub-adviser or an affiliate thereof.  All
of  the Trust's Trustees also  serve as directors or trustees  of some or all of
the other investment companies managed, administered  or advised by AIM. All  of
the  Trust's executive  officers hold  similar offices with  some or  all of the
other investment companies managed, administered or advised by AIM. Each Trustee
who is not a director, officer or employee of the Sub-adviser or any  affiliated
company  is paid aggregate  fees of $5,000 a  year, plus $300  per Fund for each
meeting of the Board attended, and reimbursed travel and other expenses incurred
in connection  with attendance  at such  meetings. Other  Trustees and  Officers
receive  no compensation or expense reimbursement from the Trust. For the fiscal
year ended October 31,  1997, Mr. Anderson, Mr.  Bayley, Mr. Patterson and  Miss

sub-administration  contract  between AIM  and the  Sub-adviser ("Administration
Sub-Contract,"   and   together   with   the   Administration   Contract,    the
"Administration  Contracts"). The  Administration Contracts  will not  be deemed
advisory contracts, as defined  under the 1940 Act.  As investment managers  and
administrators,  AIM and the Sub-adviser make  all investment decisions for each
Portfolio and, as  administrators, administer each  Portfolio's and each  Feeder
Fund's affairs. Among other things, AIM and the Sub-adviser furnish the services
and  pay  the  compensation  and  travel expenses  of  persons  who  perform the
executive, administrative, clerical and bookkeeping functions of each  Portfolio
and  each Feeder Fund and provide  suitable office space, necessary small office
equipment and utilities.
    
 
   
The Portfolio Management Contracts  may be renewed with  respect to a  Portfolio
for  additional  one-year  terms,  provided  that  any  such  renewal  has  been
specifically approved at least annually by (i) the Portfolios' Board of Trustees
or the vote of a majority  of the Portfolio's outstanding voting securities  (as
defined  in the 1940 Act) and (ii) a majority of Trustees who are not parties to
the Portfolio Management Contracts or "interested persons" of any such party (as
defined in the 1940 Act),  cast in person at a  meeting called for the  specific
purpose  of voting on such approval.  The Portfolio Management Contracts provide
that with respect to  each Portfolio, and  the Administration Contracts  provide
that  with respect to each Feeder Fund, either the Trust, each Portfolio or each
of AIM or the Sub-adviser may terminate the Contracts without penalty upon sixty
days' written  notice to  the other  party. The  Portfolio Management  Contracts
terminate automatically in the event of their assignment (as defined in the 1940
Act).

Contracts or "interested  persons" of  any such party  (as defined  in the  1940
Act),  cast in person at a meeting called  for the specific purpose of voting on
such approval. The Management Contracts provide that with respect to the  Health
Care  Fund and Telecommunications  Fund either the  Trust or each  of AIM or the
Sub-adviser may terminate the Contracts without penalty upon sixty days' written
notice to the other party.  The Management Contracts terminate automatically  in
the event of their assignment (as defined in the 1940 Act).

$266,025; and $74,485,  $147,614 and $338,578,  respectively. However, the  Sub-
adviser  reimbursed those Funds for such fees in the amounts of $18,756, $34,865
and $0; $177,376,  $0 and  $0; and  $74,485, $0  and $0,  respectively. For  the

reimbursed   the  Consumer  Products  and   Services  Portfolio  for  investment
management and  administration  fees in  the  amounts  of $16,284,  $0  and  $0,
respectively. For the same periods, the Consumer Products and Services Fund paid

respectively.
 
   
                             THE DISTRIBUTION PLANS
    
 
   
THE  CLASS A PLAN. The Trust has  adopted a Master Distribution Plan pursuant to
Rule 12b-1 under the 1940 Act relating to  the Class A shares of the Funds  (the
"Class A Plan"). The Class A Plan provides that the Class A shares pay 0.50% per
annum  of their average daily net assets as compensation to AIM Distributors for
the purpose of financing any activity  which is primarily intended to result  in
the  sale of Class  A shares. Of such  amounts, each Fund pays  a service fee of
0.25% of the average daily net assets attributable to Class A shares to selected
dealers and  other institutions  which furnish  continuing personal  shareholder
services  to their  customers who  purchase and  own Class  A shares. Activities
appropriate for financing under  the Class A Plan  include, but are not  limited
to,  the  following:  printing  of  prospectuses  and  statements  of additional
information  and  reports  for  other  than  existing  shareholders;   overhead;
preparation  and  distribution  of advertising  material  and  sales literature;
expenses of organizing and conducting  sales seminars; supplemental payments  to
dealers  and other institutions such as asset-based sales charges or as payments
of  service  fees   under  shareholder  service   arrangements;  and  costs   of
administering the Class A Plan.
    
 
   
THE CLASS B PLAN. The Trust has also adopted a Master Distribution Plan pursuant
to  Rule 12b-1 under the 1940  Act relating to Class B  shares of the Funds (the
"Class B Plan", and collectively with the Class A Plan, the "Plans"). Under  the
Class  B Plan, each Fund pays compensation to AIM Distributors at an annual rate
of 1.00% of the average daily net assets attributable to Class B shares. Of such
amount, each Fund pays a  service fee of 0.25% of  the average daily net  assets
attributable  to Class B shares to selected dealers and other institutions which
furnish continuing personal shareholder services to their customers who purchase
and own Class B shares. Amounts paid in accordance with the Class B Plan may  be
used to finance any activity primarily intended to result in the sale of Class B
shares,  including but not limited to printing of prospectuses and statements of
additional  information  and  reports  for  other  than  existing  shareholders;
overhead;  preparation  and  distribution  of  advertising  material  and  sales
literature; expenses of organizing  and conducting sales seminars;  supplemental
payments  to dealers and other institutions such as asset-based sales charges or
as payments of service fees under shareholder service arrangements; and costs of
administering the  Class B  Plan. AIM  Distributors may  transfer and  sell  its
rights  to payments  under the  Class B  Plan in  order to  finance distribution
expenditures in respect of Class B shares.
    
 
   
BOTH PLANS. Pursuant to  an incentive program, AIM  Distributors may enter  into
agreements  ("Shareholder Service Agreements")  with investment dealers selected
from time  to  time  by  AIM Distributors  for  the  provision  of  distribution
assistance  in connection with  the sale of  the Funds' shares  to such dealers'
customers, and for the provision of continuing personal shareholder services  to
customers  who may from time to time  directly or beneficially own shares of the
Funds. The distribution assistance and continuing personal shareholder  services
to  be rendered by dealers under the Shareholder Service Agreements may include,
but shall  not be  limited  to, the  following: distributing  sales  literature;
answering routine customer inquiries concerning the Fund; assisting customers in
changing  dividend options, account designations and addresses, and in enrolling
in any of the  several special investment plans  offered in connection with  the
purchase  of a Fund's shares; assisting  in the establishment and maintenance of
customer accounts and records and in the processing of
    
 
                  Statement of Additional Information Page 32

                             AIM GLOBAL THEME FUNDS
   
purchase and redemption transactions; investing dividends and any capital  gains
distributions  automatically  in  a  Fund's  shares;  and  providing  such other
information and services as a Fund or the customer may reasonably request.
    
 
   
Under the Plans, in addition  to the Shareholder Service Agreements  authorizing
payments   to  selected  dealers,  banks  may  enter  into  Shareholder  Service
Agreements authorizing  payments under  the  Plans to  be  made to  banks  which
provide services to their customers who have purchased shares. Services provided
pursuant to Shareholder Service Agreements with banks may include some or all of
the  following: answering shareholder inquiries  regarding the Funds; performing
sub-accounting; establishing and maintaining  shareholder accounts and  records;
processing  customer  purchase and  redemption transactions;  providing periodic
statements showing a shareholder's account  balance and the integration of  such
statements  with those of  other transactions and  balances in the shareholder's
other accounts serviced by the  bank; forwarding applicable prospectuses,  proxy
statements,  reports and notices to bank clients  who hold Fund shares; and such
other administrative services as  a Fund reasonably may  request, to the  extent
permitted  by applicable statute, rule or  regulation. Similar agreements may be
permitted under the Plans for  institutions which provide recordkeeping for  and
administrative services to 401(k) plans.
    
 
   
Financial  intermediaries and any other  person entitled to receive compensation
for selling Fund shares may receive different compensation for selling shares of
one particular class over another.
    
 
   
Under a Shareholder Service Agreement, each Fund agrees to pay periodically fees
to selected dealers and other institutions who render the foregoing services  to
their  customers.  The  fees  payable  under  a  Shareholder  Service  Agreement
generally will be calculated at the end of each payment period for each business
day of a  Fund during such  period at the  annual rate of  0.25% of the  average
daily  net  asset  value of  the  Fund's  shares purchased  or  acquired through
exchange. Fees calculated in  this manner shall be  paid only to those  selected
dealers  or other institutions who are dealers  or institutions of record at the
close of business on the last business day of the applicable payment period  for
the account in which each Fund's shares are held.
    
 
   
Payments pursuant to the Plans are subject to any applicable limitations imposed
by  rules of the National Association  of Securities Dealers, Inc. ("NASD"). The
Plans conform to  rules of the  NASD by  limiting payments made  to dealers  and
other   financial  institutions  who  provide  continuing  personal  shareholder
services to their customers who purchase and own shares of the Funds to no  more
than  0.25% per annum of the average  daily net assets of the funds attributable
to the customers of  such dealers or financial  institutions, and by imposing  a
cap on the total sales charges, including asset based sales charges, that may be
paid by the Fund and its respective classes.
    
 
   
AIM  Distributors does not act as principal,  but rather as agent for the Funds,
in making dealer incentive and  shareholder servicing payments under the  Plans.
These payments are an obligation of a Fund and not of AIM Distributors.
    
 
   
Prior  to  June 1,  1998, the  Trust had  adopted a  different Rule  12b-1, that
operated as  a "reimbursement-type"  plan (the  "Prior Plan").  The  information
provided below relates to payments made under the Prior Plan, which provided for
payments  to GT Global Inc., the distributor of  the Trust at the time the Prior
Plan was in effect.
    
 
   
For the  fiscal year  ended December  31,  1997, each  Fund paid  the  following
amounts under the Prior Plan:

The  Plans require AIM  Distributors to provide  the Board of  Trustees at least
quarterly with a written  report of the amounts  expended pursuant to the  Plans
and  the purposes for which  such expenditures were made.  The Board of Trustees
reviews these reports  in connection with  their decisions with  respect to  the
Plans.
    
 
   
As  required by Rule 12b-1,  the Plans and related  forms of Shareholder Service
Agreements were approved by the Board  of Trustees, including a majority of  the
trustees  who are not "interested  persons" (as defined in  the 1940 Act) of the
Trust and who have no direct or indirect financial interest in the operation  of
the  Plans or in any agreements related  to the Plans ("Qualified Trustees"). In
approving the  Plans in  accordance with  the requirements  of Rule  12b-1,  the
Trustees  considered various factors  and determined that  there is a reasonable
likelihood that  the Plans  would benefit  each  class of  each Fund  and  their
respective shareholders.
    
 
   
The Plans do not obligate the Funds to reimburse AIM Distributors for the actual
expenses  AIM Distributors  may incur  in fulfilling  its obligations  under the
Plans. Thus, even if AIM Distributors' actual expenses exceed the fee payable to
AIM Distributors thereunder at any given time,  a Fund will not be obligated  to
pay  more than that fee. If AIM Distributors'  expenses are less than the fee it
receives, AIM Distributors will retain the full amount of the fee.

<PAGE>
                             AIM GLOBAL THEME FUNDS
 
   
Unless terminated earlier in accordance with their terms, the Plans continue  in
effect  until  [June  30,  1999]  and each  year  thereafter,  as  long  as such
continuance is specifically approved at least annually by the Board of Trustees,
including a majority of the Qualified Trustees.
    
 
   
The Plans  may be  terminated  by the  vote of  a  majority of  the  Independent
Trustees,  or, with respect to a particular class,  by the vote of a majority of
the outstanding voting securities of that class.
    
 
   
Any change in the Plans that would increase materially the distribution expenses
paid by the applicable class requires shareholder approval; otherwise, it may be
amended by the  trustees, including  a majority  of the  Qualified Trustees,  by
votes  cast in person  at a meeting called  for the purpose  of voting upon such
amendment. As long as the  Plans are in effect,  the selection or nomination  of
the Qualified Trustees is committed to the discretion of the Qualified Trustees.
In the event the Class A Plan is amended in a manner which the Board of Trustees
determines  would materially increase  the charges paid under  the Class A Plan,
the Class B shares of  each Fund will no longer  convert into Class A shares  of
the  same  Fund  unless the  Class  B  shares, voting  separately,  approve such
amendment. If the Class B shareholders do not approve such amendment, the  Board
of Trustees will (i) create a new class of shares of the Fund which is identical
in  all material  respects to the  Class A shares  as they existed  prior to the
implementation of the amendment and (ii) ensure that the existing Class B shares
of the Fund  will be exchanged  or converted into  such new class  of shares  no
later  than the date the  Class B shares were scheduled  to convert into Class A
shares.
    
 
   
The principal differences between  the Class A  Plan, on the  one hand, and  the
Class B Plan, on the other hand, are: (i) the Class A Plan allows payment to AIM
Distributors  or to dealers or financial institutions  of up to 0.50% of average
daily net assets of  the Class A shares  of each Fund, as  compared to 1.00%  of
such  assets of the Funds'  Class B shares; (ii) the  Class B Plan obligates the
Class B  shares to  continue  to make  payments  to AIM  Distributors  following
termination of the Class B shares Distribution Agreement with respect to Class B
shares  sold by or attributable to  the distribution efforts of AIM Distributors
unless there has been a complete termination of the Class B Plan (as defined  in
such  Plan) and (iii) the Class B  Plan expressly authorizes AIM Distributors to
assign, transfer or pledge its rights to payments pursuant to the Class B Plan.
    
 
   
                                THE DISTRIBUTOR
    
 
   
Information concerning  AIM Distributors  and the  continuous offering  of  each
Fund's shares is set forth in the Prospectus under the headings "How to Purchase
Shares"  and  "Terms and  Conditions of  Purchase  of the  AIM Funds."  A Master
Distribution Agreement with AIM Distributors relating to the Class A and Class B
shares of the Funds was approved by the Board of Trustees on             , 1998.
Both such Master Distribution  Agreements are hereinafter collectively  referred
to as the "Distribution Agreements."
    
 
   
The Distribution Agreements provide that AIM Distributors will bear the expenses
of  printing from the final proof  and distributing each Fund's prospectuses and
statements of additional information  relating to public  offerings made by  AIM
Distributors   pursuant  to  the  Distribution   Agreements  (other  than  those
prospectuses and statements  of additional information  distributed to  existing
shareholders  of the Fund), and any promotional  or sales literature used by AIM
Distributors or furnished by AIM Distributors to dealers in connection with  the
public  offering of  each Fund's  shares, including  expenses of  advertising in
connection with such public  offerings. AIM Distributors  has not undertaken  to
sell any specified number of shares of any classes of any Fund.
    
 
   
AIM  Distributors expects  to pay  sales commissions  from its  own resources to
dealers and institutions who  sell Class B  shares of the Funds  at the time  of
such  sales. Payments  with respect  to Class  B shares  will equal  4.0% of the
purchase price of the Class B shares sold by the dealer or institution, and will
consist of a sales commission equal to 3.75% of the purchase price of the  Class
B  shares sold  plus an  advance of  the first  year service  fee of  0.25% with
respect to such shares.  The portion of the  payments to AIM Distributors  under
the  Class  B Plan  which  constitutes an  asset-based  sales charge  (0.75%) is
intended in part to permit  AIM Distributors to recoup  a portion of such  sales
commissions  plus  financing costs.  AIM Distributors  anticipates that  it will
require a  number of  years  to recoup  from Class  B  Plan payments  the  sales
commissions paid to dealers and institutions in connection with sales of Class B
shares.  In  the  future,  if  multiple distributors  serve  a  Fund,  each such
distributor (or  its  assignee or  transferee)  would  receive a  share  of  the
payments  under the  Class B  Plan based on  the portion  of the  Fund's Class B
shares sold by or attributable to the distribution efforts of that distributor.
    
 
   
The Trust (on behalf of any class  of a Fund) or AIM Distributors may  terminate
the  Distribution Agreements on sixty (60) days' written notice without penalty.
The Distribution Agreements will terminate  automatically in the event of  their
assignment.   In  the  event  the  Class  B  shares  Distribution  Agreement  is
terminated, AIM Distributors would continue  to receive payments of asset  based
distribution  fees in respect of the  outstanding Class B shares attributable to
the distribution efforts of AIM Distributors; provided, however, that a complete
termination of the Class B Plan (as defined in such

                             AIM GLOBAL THEME FUNDS
   
Plan) would terminate all payments to AIM Distributors. Termination of the Class
B Plan or Distribution Agreement does not affect the obligation of the Funds and
their Class B shareholders to pay contingent deferred sales charges.
    
 
   
The following chart reflects the total sales charges paid in connection with the
sale of Class A shares of each Fund and the amount retained by GT Global,  Inc.,
the  Trust's  distributor prior  to  June 1,  1998,  for the  fiscal  year ended

TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The  Transfer Agency  and Service  Agreement between  the Trust  and A  I M Fund
Services, Inc. ("AFS"), a registered transfer agent and wholly-owned  subsidiary
of  AIM, provides  that AFS  will perform  certain shareholder  services for the
Funds for a fee per account serviced. The Transfer Agency and Service  Agreement
provides  that AFS will receive a per account fee plus out-of-pocket expenses to
process orders for purchases, redemptions  and exchanges of shares; prepare  and
transmit  payments  for  dividends  and  distributions  declared  by  the Funds;
maintain  shareholder  accounts  and   provide  shareholders  with   information
regarding  the  Funds  and  their  accounts.  The  Transfer  Agency  and Service
Agreement became effective on September 8, 1998. The Sub-adviser also serves  as
each Fund's pricing and accounting agent. For the fiscal years ended October 31,
1995,  1996 and  1997, the  accounting services fees  for the  Health Care Fund,
Telecommunications Fund, Financial Services Fund, Infrastructure Fund, Resources
Fund and  Consumer  Products  and  Services  Fund  were  $30,660,  $141,582  and
$153,780;  $170,297, $621,480  and $493,322;  $616, $3,493  and $12,292; $5,836,
$21,910 and $27,303; $1,931, $14,761 and $34,698; and $318, $14,778 and $43,330,
respectively.
    
 
EXPENSES OF THE FUNDS AND OF THE PORTFOLIOS
   
Each Fund  and  each  Portfolio  pays  all expenses  not  assumed  by  AIM,  the
Sub-adviser,  AIM  Distributors and  other  agents. These  expenses  include, in
addition to the advisory, administration, distribution, transfer agency, pricing
and accounting  agency  and brokerage  fees  discussed above,  legal  and  audit
expenses, custodian fees, trustees' fees, organizational fees, fidelity bond and
other  insurance premiums, taxes, extraordinary expenses and expenses of reports
and prospectuses sent  to existing  investors. The allocation  of general  Trust
expenses and expenses shared among the Funds and other funds organized as series
of  the Trust are allocated  on a basis deemed fair  and equitable, which may be
based on the  relative net  assets of  the Funds or  the nature  of the  service
performed and relative applicability to the Funds. Expenditures, including costs
incurred  in connection with the purchase or sale of portfolio securities, which
are capitalized  in accordance  with  generally accepted  accounting  principles
applicable  to investment companies, are accounted  for as capital items and not
as expenses. The ratio of each Fund's expenses to its relative net assets can be
expected to  be higher  than the  expense ratios  of funds  investing solely  in
domestic  securities,  since  the cost  of  maintaining the  custody  of foreign
securities and the rate of investment management  fees paid by the Funds or  the
Portfolios  generally  are higher  than the  comparable  expenses of  such other
funds.

                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
 
   
The net asset value per  share of each Fund is  normally determined daily as  of
the  close of trading  of the New  York Stock Exchange  ("NYSE") (generally 4:00
p.m. Eastern time)  on each  business day  of the Fund.  In the  event the  NYSE
closes  early (i.e., before 4:00 p.m. Eastern time) on a particular day, the net
asset value of a Fund is determined as of the close of the NYSE on such day. Net
asset value  per  share  is determined  by  dividing  the value  of  each  Theme
Portfolio's  securities, cash and  other assets (including  interest accrued but
not collected)  attributable to  a particular  class, less  all its  liabilities
(including  accrued expenses and dividends  payable) attributable to that class,
by the total number of shares  outstanding of that class. Determination of  each
Fund's  net asset value per share is  made in accordance with generally accepted
accounting principles.
    
 
   
Each equity security held by a Theme Portfolio is valued at its last sales price
on the exchange where the security  is principally traded or, lacking any  sales
on  a particular day, the security is valued at the mean between the closing bid
and asked  prices on  that day.  Each security  traded in  the  over-the-counter
market  (but not  including securities  reported on  the NASDAQ  National Market
System) is valued at the mean between  the last bid and asked prices based  upon
quotes furnished by market makers for such securities. Each security reported on
the  NASDAQ National  Market System  is valued  at the  last sales  price on the
valuation date or absent a last sales price, at the mean between the closing bid
and asked prices on that day. Debt securities are valued on the basis of  prices
provided  by  an independent  pricing service.  Prices  provided by  the pricing
service may be determined without exclusive  reliance on quoted prices, and  may
reflect  appropriate factors such as  institution-size trading in similar groups
of securities,  developments  related  to special  securities,  yield,  quality,
coupon  rate, maturity,  type of  issue, individual  trading characteristics and
other market  data.  Securities for  which  market quotations  are  not  readily
available  or are questionable  are valued at  fair value as  determined in good
faith by  or  under  the  supervision  of  the  Trust's  officers  in  a  manner
specifically  authorized by the Board of Trustees. Short-term obligations having
60 days or  less to  maturity are  valued on the  basis of  amortized cost.  For
purposes of determining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE.
    
 
   
Generally,  trading  in  foreign securities,  corporate  bonds,  U.S. Government
securities and money market instruments  is substantially completed each day  at
various times prior to the close of the NYSE. The values of such securities used
in  computing the net asset  value of each Fund's  shares are determined at such
times. Foreign currency exchange  rates are also  generally determined prior  to
the  close  of  the NYSE.  Occasionally,  events  affecting the  values  of such
securities and such  exchange rates may  occur between the  times at which  such
values  are determined and the close of the  NYSE which will not be reflected in
the computation of a Fund's net asset value. If events materially affecting  the
value of such securities occur during such period, then these securities will be
valued  at  their  fair  value as  determined  in  good faith  by  or  under the
supervision of the Board of Trustees of the Fund and the Portfolio.

A complete  description of  the  manner in  which shares  of  the Funds  may  be
purchased appears in the Funds' Prospectuses under the headings "How to Purchase
Shares,"  "Terms  and Conditions  of Purchases  of the  AIM Funds"  and "Special
Plans."
    
 
   
The sales charge normally  deducted on purchases  of Class A  shares is used  to
compensate  AIM  Distributors  and  participating  dealers  for  their  expenses
incurred in connections  with the  distribution of  the Funds'  Class A  shares.
Since  there  is  little  expenses  associated  with  unsolicited  orders placed
directly with AIM  Distributors by  persons who, because  of their  relationship
with  the Funds or with AIM and its  affiliates, are familiar with the Funds, or
whose programs for purchase involve little expense (e.g., because of the size of
the transaction  and shareholder  records required),  AIM Distributors  believes
that  it is appropriate and in the  Funds' best interests that such persons, and
certain other  persons whose  purchases  result in  relatively low  expenses  of
distribution,   be  permitted   to  purchase  Class   A  shares   of  the  Funds

through AIM Distributors without payment of a sales charge. The persons who  may
purchase Class A shares of the Funds without a sales charge are set forth in the
Funds'  Prospectuses. In  addition, the  Funds offer  programs such  as Right of
Accumulation and Letter of Intent, which are described in the Prospectuses, that
are designed to permit investors to  aggregate purchases of different funds,  or
separate purchases over time, in order to qualify for a lower sales charge rate.
See  "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
Sales Charges" in the Prospectuses.
    
 
   
Class B shares will automatically convert into  Class A shares of the same  Fund
eight  years following  the end of  the calendar  month in which  a purchase was
made. For the purpose of calculating the holding period required for  conversion
of  Class B shares,  the initial issuance of  Class B shares  shall mean (i) the
date on  which such  Class B  shares were  issued, or  (ii) for  Class B  shares
obtained  through an exchange, or  a series of exchanges,  the date on which the
original Class B  shares were  issued. For purposes  of conversion  to Class  A,
Class  B  shares  purchased  through the  reinvestment  of  dividends  and other
distributions paid in  respect of  Class B  shares will  be held  in a  separate
sub-account.  Each time any Class B  shares in the shareholder's regular account
(other than those in the sub-account) convert to Class A, a pro rata portion  of
the  Class B shares in the sub-account will also convert to Class A. The portion
will be determined by the ratio that the shareholder's Class B shares converting
to Class A bears to the shareholder's total Class B shares not acquired  through
dividends and other distributions.
    
 
   
The  availability  of  the  conversion  feature  is  subject  to  the continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions  paid  on  Class  A  and  Class  B  shares  will  not  result   in
"preferential  dividends" under the  Code and the conversion  of shares does not
constitute a taxable event.  If the conversion feature  ceased to be  available,
the Class B shares beyond the eighth year. AIM and the Sub-adviser has no reason
to  believe that this  condition for the availability  of the conversion feature
will not be met.
    
 
   
Class A shares that are subject to  a contingent deferred sales charge and  that
were  purchased before June 1,  1998 are entitled to  the following waivers from
the contingent deferred sales charge otherwise due upon redemption: (1)  minimum
required  distributions made in connection with  an IRA, Keogh plan or custodial
account under Section  403(b) of  the Code  or other  retirement plan  following
attainment  of age  70 1/2;  (2) total or  partial redemptions  resulting from a
distribution   following   retirement   in   the   case   of   a   tax-qualified
employer-sponsored  retirement  plan;  (3)  when  a  redemption  results  from a
tax-free return of an excess contribution  pursuant to Section 408(d)(4) or  (5)
of  the Code or  from the death  or disability of  the employee; (4) redemptions
pursuant to a Fund's right  to liquidate a shareholder's account  involuntarily;
(5)    redemptions    pursuant   to    distributions   from    a   tax-qualified
employer-sponsored retirement plan, which  is invested in  AIM Funds, which  are
permitted  to be made without penalty pursuant  to the Code, other than tax-free
rollovers or transfers of  assets, and the proceeds  of which are reinvested  in
AIM   Funds;  (6)  redemptions  made  in  connection  with  participant-directed
exchanges between options in an employer-sponsored benefit plan; (7) redemptions
made for the  purpose of providing  cash to fund  a loan to  a participant in  a
tax-qualified  retirement  plan;  (8)  redemptions  made  in  connection  with a
distribution from any retirement plan or account that is permitted in accordance
with the  provisions  of  Section  72(t)(2) of  the  Code  and  the  regulations
promulgated  thereunder; (9) redemptions made  in connection with a distribution
from any  retirement plan  or account  that  involves the  return of  an  excess
deferral  amount pursuant to Section 401(k)(8) or Section 402(g)(2) of the Code;
(10) redemptions  made  in  connection  with a  distribution  from  a  qualified
profit-sharing  or stock bonus plan described in Section 401(k) of the Code to a
participant or  beneficiary  under Section  401(k)(2)(B)(IV)  of the  Code  upon
hardship  of the  covered employee  (determined pursuant  to Treasury Regulation
Section 1.401(k)-1(d)(2)); and (11)  redemptions made by or  for the benefit  of
certain  states, counties  or cities,  or any  instrumentalities, departments or
authorities thereof, where such entities are prohibited or limited by applicable
law from paying a sales charge or commission.
    
 
   
Class B shares purchased before June 1, 1998 are subject to the waivers from the
contingent deferred sales charge otherwise due upon redemptions, in addition  to
the  waivers  provided for  redemptions of  currently issued  Class B  shares as
described in the Prospectus: (1) total  or partial redemptions resulting from  a
distribution   following   retirement   in   the   case   of   a   tax-qualified
employer-sponsored  retirement;  (2)  minimum  required  distributions  made  in
connection  with an IRA, Keogh plan or custodial account under Section 403(b) of
the Code or  other retirement plan  following attainment  of age 70  1/2; (3)  a
one-time  reinvestment in Class  B shares of a  Fund within 180  days of a prior
redemption; (4)  redemptions  pursuant  to distributions  from  a  tax-qualified
employer-sponsored  retirement plan, which  is invested in  AIM Funds, which are
permitted to be made without penalty  pursuant to the Code, other than  tax-free
rollovers  or transfers of assets,  and the proceeds of  which are reinvested in
AIM  Funds;  (5)  redemptions  made  in  connection  with   participant-directed
exchanges between options in an employer-sponsored benefit plan; (6) redemptions
made  for the purpose  of providing cash  to fund a  loan to a  participant in a
tax-qualified retirement  plan;  (7)  redemptions  made  in  connection  with  a
distribution from any retirement plan or account that is permitted in accordance
with  the  provisions  of  Section  72(t)(2) of  the  Code  and  the regulations
promulgated thereunder; (8) redemptions made  in connection with a  distribution
from a qualified profit-

sharing  or  stock bonus  plan  described in  Section 401(k)  of  the Code  to a
participant or  beneficiary  under Section  401(k)(2)(B)(IV)  of the  Code  upon
hardship  of the  covered employee  (determined pursuant  to Treasury Regulation
Section 1.401(k)-1(d)(2)); and  (9) redemptions made  by or for  the benefit  of
certain  states, counties  or cities,  or any  instrumentalities, departments or
authorities thereof where such entities are prohibited or limited by  applicable
law from paying a sales charge or commission.
 
   
For  purposes of  a Letter  of Intent entered  into prior  to June  1, 1998, any
registered investment  adviser, trust  company or  bank trust  department  which
exercises  investment  discretion and  which intends  within thirteen  months to
invest $500,000 or more can be  treated as a single purchaser, provided  further
that  such  entity places  all purchases  and  redemption orders.  Such entities
should be prepared to establish their qualifications for such treatment.
    
 
   
Complete information concerning the method of exchanging shares of the Funds for
shares of the other AIM Funds is set forth in the Prospectuses under the heading
"Exchange Privilege."
    
 
   
Information concerning  redemption of  the Funds'  shares is  set forth  in  the
Prospectuses under the heading "How to Redeem Shares." In addition to the Funds'
obligation  to redeem shares, AIM Distributors  may also repurchase shares as an
accommodation to shareholders. To  effect a repurchase,  those dealers who  have
executed  Selected Dealer Agreements with AIM  Distributors must phone orders to
the order desk  of the Funds  at (800)  959-4246 and guarantee  delivery of  all
required  documents in  good order.  A repurchase is  effected at  the net asset
value per share  of the  applicable Fund  next determined  after the  repurchase
order  is received. Such an  arrangement is subject to  timely receipt by AFS of
all required documents in good order. If such documents are not received  within
a  reasonable  time  after  the  order  is  placed,  the  order  is  subject  to
cancellation. While there is no charge imposed by a Fund or by AIM  Distributors
(other  than any  applicable contingent deferred  sales charge)  when shares are
redeemed or repurchased, dealers may charge a fair service fee for handling  the
transaction.
    
 
   
The  right of redemption may be suspended  or the date of payment postponed when
(a) trading on  the NYSE is  restricted, as determined  by applicable rules  and
regulations  of the SEC, (b) the NYSE is closed for other than customary weekend
and holiday closings, (c) the SEC has by order permitted such suspension, or (d)
an emergency as  determined by the  SEC exists making  disposition of  portfolio
securities  or  the  valuation  of  the net  assets  of  a  Fund  not reasonably
practicable.
    
 
   
A Fund's net  asset value is  calculated by dividing  the number of  outstanding
shares  into the net assets of  the Fund. Net assets are  the excess of a Fund's
assets over its liabilities. A more detailed description of how each Fund's  net
asset  value  is  calculated  appears  in  the  Prospectuses  under  the heading
"Determination of Net Asset Value."
    
 
   
QUALIFYING FOR A REDUCED FRONT-END SALES CHARGE. As described in the Prospectus,
the front-end sales charge  for Class A shares  is calculated by multiplying  an
investor's  total investment by the applicable sales charge rate. The applicable
rate varies with the amount invested. The Funds offer programs such as Right  of
Accumulation  and Letter of  Intent, which are described  in the Prospectus, and
are designed to permit investors to  aggregate purchases of different funds,  or
separate purchases over time, in order to qualify for a lower sales charge rate.
See  "Terms and Conditions of Purchase of the AIM Funds -- Reductions in Initial
Sales Charges" in the Prospectus.
    
 
   
PROGRAMS AND SERVICES FOR SHAREHOLDERS.  The Funds provide certain services  for
shareholders  and  certain  investment  or  redemption  programs.  See "Exchange
Privilege"  and  "How  to  Redeem  Shares"  in  the  Prospectus.  All  inquiries
concerning  these programs should be made directly  to A I M Fund Services, Inc.
P.O. Box 4739, Houston, Texas 77210-4739, toll free at (800) 959-4246.
    
 
   
DIVIDEND ORDER.  Dividends may  be paid  to someone  other than  the  registered
owner, or sent to an address other than the address of record. (Please note that
signature  guarantees are required to effect  this option.) An investor also may
direct that his or her dividends be invested  in one of the other AIM Funds  and
there  is no  sales charge  for these  investments; initial  investment minimums
apply.  See  "Dividends,  Distributions  and   Tax  Matters  --  Dividends   and
Distributions"  in the  Prospectus. To effect  this option,  please contact your
authorized dealer. For more information concerning AIM Funds other than those in
the Trust,  please obtain  a current  prospectus by  contacting your  authorized
dealer,  by writing to A I M Fund  Services, Inc., P.O. Box 4739, Houston, Texas
77210-4739, or by calling toll free (800) 959-4246.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUNDS
   
Each Fund is treated as a separate corporation for federal income tax  purposes.
To  continue to qualify for treatment  as a regulated investment company ("RIC")
under the Code, each Fund must  distribute to its shareholders for each  taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income, net short-term capital gain and net gains from certain
foreign  currency  transactions)  ("Distribution  Requirement")  and  must  meet
several additional requirements. With respect  to each Fund, these  requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each  taxable year from dividends, interest, payments with respect to securities
loans and gains  from the  sale or other  disposition of  securities or  foreign
currencies,  or other income  (including gains from  options, Futures or Forward
Contracts) derived with respect  to its business of  investing in securities  or
those   currencies   ("Income   Requirement");  and   (2)   the  Diversification
Requirements. Each Feeder Fund, as  an investor in its corresponding  Portfolio,
is  deemed to own a proportionate share of the Portfolio's assets, and to earn a
proportionate share  of  the Portfolio's  income,  for purposes  of  determining
whether the Fund satisfies the requirements described above to qualify as a RIC.
    
 
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent  it fails to distribute by the end of any calendar year substantially all
of its  ordinary income  for  that year  and capital  gain  net income  for  the
one-year period ending on October 31 of that year, plus certain other amounts.
 
See  the next section  for a discussion  of the tax  consequences to each Feeder
Fund of  hedging transactions  engaged in,  and investments  in passive  foreign
investment companies ("PFICs") and other foreign securities by its corresponding
Portfolio  and  to the  Health Care  Fund and  Telecommunications Fund  of those
transactions and investments.
 
TAXATION OF THE THEME PORTFOLIOS
 
    THE PORTFOLIOS AND THEIR RELATIONSHIP TO THE FEEDER FUNDS. Each Portfolio is
treated as a separate partnership for federal  income tax purposes and is not  a
"publicly  traded partnership."  As a result,  each Portfolio is  not subject to
federal  income  tax;  instead,  each  Feeder  Fund,  as  an  investor  in   its
corresponding  Portfolio, is  required to take  into account  in determining its
federal income tax liability its share of the Portfolio's income, gains, losses,
deductions and  credits, without  regard to  whether it  has received  any  cash
distributions from the Portfolio. Each Portfolio also is not subject to Delaware
income or franchise tax.
 
Because, as noted above, each Feeder Fund is deemed to own a proportionate share
of  its corresponding Portfolio's  assets, and to earn  a proportionate share of
its corresponding Portfolio's  income, for purposes  of determining whether  the
Fund  satisfies the requirements to qualify as  a RIC, each Portfolio intends to
conduct its operations so that its  corresponding Fund will be able to  continue
to satisfy all those requirements.
 
Distributions  to  each Feeder  Fund from  its corresponding  Portfolio (whether
pursuant to a partial  or complete withdrawal or  otherwise) will not result  in
the  Fund's recognition  of any  gain or loss  for federal  income tax purposes,
except that  (1)  gain  will be  recognized  to  the extent  any  cash  that  is
distributed  exceeds the Fund's  basis for its interest  in the Portfolio before
the distribution, (2) income or gain  will be recognized if the distribution  is
in  liquidation of the  Fund's entire interest  in the Portfolio  and includes a
disproportionate share of any unrealized receivables held by the Portfolio,  and
(3)  loss will  be recognized if  a liquidation distribution  consists solely of
cash and/or unrealized receivables. Each Feeder Fund's basis for its interest in
its corresponding Portfolio  generally will  equal the  amount of  cash and  the
basis of any property the Fund invests in the Portfolio, increased by the Fund's
share of the Portfolio's net income and gains and decreased by (a) the amount of
cash and the basis of any property the Portfolio distributes to the Fund and (b)
the Fund's share of the Portfolio's losses.
 
    FOREIGN  TAXES. Dividends  and interest received  by a  Theme Portfolio, and
gains realized thereby,  may be subject  to income, withholding  or other  taxes
imposed  by foreign countries and U.S.  possessions ("foreign taxes") that would
reduce the yield and/or total return on its securities. Tax conventions  between
certain  countries and the United States  may reduce or eliminate foreign taxes,
however, and many  foreign countries  do not impose  taxes on  capital gains  in
respect of
 
                  Statement of Additional Information Page 40
<PAGE>
                             AIM GLOBAL THEME FUNDS
investments  by foreign  investors. If more  than 50%  of the value  of a Fund's
total  assets  (taking  into  account,  in  the  case  of  a  Feeder  Fund,  its
proportionate share of its corresponding Portfolio's assets) at the close of its
taxable  year consists of  securities of foreign corporations,  the Fund will be
eligible to, and may,  file an election with  the Internal Revenue Service  that
will  enable its shareholders, in effect, to  receive the benefit of the foreign
tax credit with respect to any foreign taxes paid by it (taking into account, in
the case of a Feeder Fund, its proportionate share of any foreign taxes paid  by
its  corresponding  Portfolio)  (a  "Fund's  foreign  taxes").  Pursuant  to the
election, a Fund would treat those  taxes as dividends paid to its  shareholders
and each shareholder would be required to (1) include in gross income, and treat
as  paid by him, his share  of the Fund's foreign taxes,  (2) treat his share of
those taxes and of any dividend paid by the Fund that represents its income from
foreign and U.S.  possessions sources  (taking into account,  in the  case of  a
Feeder  Fund, its  proportionate share  of its  corresponding Portfolio's income
from those sources) as his own income  from those sources and (3) either  deduct
the  taxes deemed paid by him in computing his taxable income or, alternatively,
use the foregoing information in calculating the foreign tax credit against  his
federal income tax. Each Fund will report to its shareholders shortly after each
taxable  year their  respective shares  of the  Fund's foreign  taxes and income
(taking into account, in the case of  a Feeder Fund, its proportionate share  of
its  corresponding Portfolio's income) from sources within foreign countries and
U.S. possessions if it makes this election. Pursuant to the Taxpayer Relief  Act
of  1997 ("Tax Act"), individuals  who have no more  than $300 ($600 for married
persons filing jointly) of  creditable foreign taxes included  on Form 1099  and
all  of whose foreign source  of income is "qualified  passive income" may elect
each year  to  be exempt  from  the  extremely complicated  foreign  tax  credit
limitation and will be able to claim a foreign tax credit without having to file
the detailed Form 1116 that otherwise is required.
 
   
    PASSIVE FOREIGN INVESTMENT COMPANIES. Each Theme Portfolio may invest in the
stock  of PFICs.  A PFIC is  a foreign  corporation -- other  than a "controlled
foreign corporation" (I.E., a  foreign corporation in which,  on any day  during
its  taxable year, more than  50% of the total voting  power of all voting stock
therein or the total value of  all stock therein is owned, directly,  indirectly
or  constructively,  by  "U.S.  shareholders,"  defined  as  U.S.  persons  that
individually own, directly, indirectly or  constructively, at least 10% of  that
voting  power) as to which the Theme  Portfolio is a U.S. shareholder (effective
with respect to each Fund for their taxable year beginning November 1, 1998)  --
that,  in general, meets either of the following  tests: (1) at least 75% of its
gross income is passive or (2) an average of at least 50% of its assets produce,
or are held for the production of, passive income. Under certain  circumstances,
a  Fund will be subject  to federal income tax  on a part (or,  in the case of a
Feeder Fund, its  proportionate share of  a part) of  any "excess  distribution"
received  by  it  (or,  in the  case  of  a Feeder  Fund,  by  its corresponding
Portfolio) on the stock of a PFIC or of any gain on the Fund's (or, in the  case
of  a  Feeder Fund,  its corresponding  Portfolio's)  disposition of  that stock
(collectively  "PFIC  income"),  plus  interest   thereon,  even  if  the   Fund
distributes  the  PFIC income  as a  taxable dividend  to its  shareholders. The
balance of the  PFIC income will  be included in  the Fund's investment  company
taxable  income and,  accordingly, will not  be taxable  to it to  the extent it
distributes that income to its shareholders.
    
 
If a  Theme Portfolio  invests in  a PFIC  and elects  to treat  the PFIC  as  a
"qualified  electing  fund"  ("QEF"), then  in  lieu  of the  foregoing  tax and
interest obligation, the Theme  Portfolio (or, in the  case of a Portfolio,  its
corresponding  Feeder Fund) would be required to include in income each year its
pro rata  share  (taking  into account,  in  the  case of  a  Feeder  Fund,  its
proportionate  share of  its corresponding  Portfolio's pro  rata share)  of the
QEF's ordinary earnings and net capital gain (I.E., the excess of net  long-term
capital  gain over net short-term capital loss)  -- which most likely would have
to be distributed by the  Theme Portfolio (or, in the  case of a Portfolio,  its
corresponding  Feeder Fund)  to satisfy  the Distribution  Requirement and avoid
imposition of  the Excise  Tax  -- even  if those  earnings  and gain  were  not
received  thereby from the QEF. In most  instances it will be very difficult, if
not impossible, to make this election because of certain requirements thereof.
 
A holder of stock in any PFIC may  elect to include in ordinary income for  each
taxable  year beginning after 1997 the excess,  if any, of the fair market value
of the  stock over  the adjusted  basis  therein as  of the  end of  that  year.
Pursuant  to the election, a deduction (as  an ordinary, not capital, loss) also
will be allowed for the excess, if  any, of the holder's adjusted basis in  PFIC
stock over the fair market value thereof as of the taxable year-end, but only to
the  extent of any net mark-to-market gains  with respect to that stock included
in income  for prior  taxable years.  The adjusted  basis in  each PFIC's  stock
subject  to  the election  will be  adjusted  to reflect  the amounts  of income
included and deductions taken thereunder. Regulations proposed in 1992  provided
a similar election with respect to the stock of certain PFICs.
 
    OPTIONS,  FUTURES AND  FOREIGN CURRENCY TRANSACTIONS.  The Theme Portfolios'
use of hedging transactions,  such as selling  (writing) and purchasing  options
and  Futures and  entering into Forward  Contracts, involves  complex rules that
will determine,  for federal  income  tax purposes,  the amount,  character  and
timing  of recognition  of the  gains and losses  a Theme  Portfolio realizes in
connection therewith. Gains from the  disposition of foreign currencies  (except
certain  gains  that may  be  excluded by  future  regulations), and  gains from
options,   Futures    and    Forward    Contracts    derived    by    a    Theme
 
                  Statement of Additional Information Page 41
<PAGE>
                             AIM GLOBAL THEME FUNDS
Portfolio  with respect  to its business  of investing in  securities or foreign
currencies, will qualify as permissible income under the Income Requirement  for
that  Theme Portfolio (or, in the case  of a Portfolio, its corresponding Feeder
Fund).
 
Futures and  Forward Contracts  that are  subject to  section 1256  of the  Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts") and that are  held by a  Theme Portfolio at the  end of its  taxable
year generally will be deemed to have been sold at that time at market value for
federal income tax purposes. Sixty percent of any net gain or loss recognized on
these  deemed sales, and  60% of any net  gain or loss  realized from any actual
sales of Section 1256  Contracts, will be treated  as long-term capital gain  or
loss,  and the balance will be treated  as short-term capital gain or loss. That
60% portion  will qualify  for the  reduced maximum  tax rates  on  noncorporate
taxpayers'  net capital gain enacted by the Tax Act -- 20% (10% for taxpayers in
the 15% marginal  tax bracket) for  gain recognized on  capital assets held  for
more  than  18  months  --  instead  of  the  28%  rate  in  effect  before that
legislation, which now  applies to gain  recognized on capital  assets held  for
more than one year but not more than 18 months.
 
Section  988 of the Code also may apply to gains and losses from transactions in
foreign currencies,  foreign-currency-denominated debt  securities and  options,
Futures  and Forward  Contracts on foreign  currencies ("Section  988" gains and
losses). Each Section  988 gain  or loss  generally is  computed separately  and
treated as ordinary income or loss. In the case of overlap between sections 1256
and  988, special provisions  determine the character and  timing of any income,
gain or loss. Each Theme Portfolio attempts to monitor section 988  transactions
to minimize any adverse tax impact.
 
If  a Theme Portfolio  has an "appreciated financial  position" -- generally, an
interest (including an interest through  an option, Futures or Forward  Contract
or  short sale) with respect to any stock, debt instrument (other than "straight
debt") or  partnership interest  the  fair market  value  of which  exceeds  its
adjusted  basis  --  and  enters  into a  "constructive  sale"  of  the  same or
substantially similar property, the  Theme Portfolio will  be treated as  having
made  an actual sale  thereof, with the  result that gain  will be recognized at
that time. A constructive sale generally consists of a short sale, an offsetting
notional principal contract  or Futures or  Forward Contract entered  into by  a
Theme  Portfolio or a related  person with respect to  the same or substantially
similar property. In addition, if the appreciated financial position is itself a
short sale  or  such a  contract,  acquisition  of the  underlying  property  or
substantially similar property will be deemed a constructive sale.
 
TAXATION OF THE FUNDS' SHAREHOLDERS
   
Dividends  and  other  distributions  declared  by a  Fund  in,  and  payable to
shareholders of record as  of a date  in, October, November  or December of  any
year  will  be  deemed  to have  been  paid  by  the Fund  and  received  by the
shareholders on December 31 of  that year if the  distributions are paid by  the
Fund  during  the following  January. Accordingly,  those distributions  will be
taxed to shareholders for the year in which that December 31 falls.
    
 
If Fund shares are sold at a loss  after being held for six months or less,  the
loss  will be treated as  long-term, instead of short-term,  capital loss to the
extent of any  capital gain  distributions received on  those shares.  Investors
also should be aware that if shares are purchased shortly before the record date
for  any dividend or other distribution, the shareholder will pay full price for
the shares and receive some portion of the price back as a taxable distribution.
 
Dividends paid by a  Fund to a shareholder  who, as to the  United States, is  a
nonresident  alien individual, nonresident alien fiduciary of a trust or estate,
foreign corporation  or foreign  partnership ("foreign  shareholder")  generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding  will not apply, however, to a dividend  paid by a Fund to a foreign
shareholder that is "effectively connected with  the conduct of a U.S. trade  or
business,"  in which case the  reporting and withholding requirements applicable
to domestic shareholders  will apply. A  distribution of net  capital gain by  a
Fund  to a foreign shareholder generally will  be subject to U.S. federal income
tax (at the rates  applicable to domestic persons)  only if the distribution  is
"effectively  connected" or  the foreign  shareholder is  treated as  a resident
alien individual for federal income tax purposes.
 
The foregoing  is a  general  and abbreviated  summary  of certain  federal  tax
considerations  affecting  the  Funds, their  shareholders  and  the Portfolios.
Investors are  urged  to  consult  their own  tax  advisers  for  more  detailed
information  and for  information regarding any  foreign, state  and local taxes
applicable to distributions received from a Fund.

Boston,  Massachusetts  02110,  acts  as  custodian  of  the  Funds'  and  Theme
Portfolios' assets. State Street is authorized to establish and has  established
separate  accounts in  foreign currencies and  to cause securities  of the Theme
Portfolios to be  held in  separate accounts outside  the United  States in  the
custody of non-U.S. banks.
 
INDEPENDENT ACCOUNTANTS
   
The    Trust's    and    Theme   Portfolios'    independent    accountants   are
                        conducts annual audits of the Portfolios' and the Funds'

Fund's  federal and  state income  tax returns and  consults with  the Trust and
Global Investment Portfolio as to matters of accounting, regulatory filings, and

The audited financial  statements of  the Trust  included in  this Statement  of
Additional Information have been examined by                         , as stated
in  their  opinion appearing  herein,  and are  included  in reliance  upon such
opinion given  upon the  authority of  that firm  as experts  in accounting  and
auditing.
    
 
   
SHAREHOLDER LIABILITY
    
   
Under  Delaware law,  the shareholders of  the Trust enjoy  the same limitations
extended to shareholders of private, for-profit corporations. There is a  remote
possibility, however, that under certain circumstances shareholders of the Trust
may  be held personally  liable for the Trust's  obligations. However, the Trust
Agreement disclaims shareholder liability for  acts or obligations of the  Trust
and  requires  that  notice  of  such disclaimer  be  given  in  each agreement,
obligation or instrument entered into or executed by the Trust or a trustee. The
Trust Agreement provides  for indemnification  from the Trust  property for  all
losses  and expenses of  any shareholder held personally  liable for the Trust's
obligations. Thus, the risk of a shareholder incurring financial loss on account
of such liability is limited to circumstances in which the Trust itself would be
unable to meet  its obligations and  where the other  party was held  not to  be
bound by the disclaimer.
    
 
NAMES
Prior  to May 29, 1998, AIM Global  Consumer Products and Services Fund operated
under the name  of GT  Global Consumer Products  and Services  Fund; AIM  Global
Financial  Services Fund operated under the name of GT Global Financial Services
Fund; AIM Global Health Care  Fund operated under the  name of GT Global  Health
Care  Fund; AIM Global Infrastructure Fund operated  under the name of GT Global
Infrastructure Fund; AIM  Global Resources Fund  operated under the  name of  GT
Global  Natural Resources Fund; and  AIM Global Telecommunications Fund operated
under the name of GT Global Telecommunications Fund.
 
SPECIAL SERVICING AGREEMENT
   
Subject to receipt of an exemptive order from the SEC, the Funds will be parties
to a Special Servicing Agreement ("Agreement") among the Trust on behalf of  the
Funds,  AIM Series Trust  on behalf of  its sole series,  AIM Global Trends Fund
("Global Trends Fund"), AIM, the Sub-adviser and AFS. The Agreement will provide
that, if the Trust's  Board of Trustees  determines that a  Fund's share of  the
aggregate  expenses of Global Trends Fund is  less than the estimated savings to
the Fund from  the operation of  Global Trends  Fund, the Fund  will bear  those
expenses  in proportion to the average daily value of its shares owned by Global
Trends Fund, provided  that no Fund  will bear  such expenses in  excess of  the
estimated savings to it. Those savings are expected to result primarily from the
elimination  of numerous  separate shareholder accounts  that are  or would have
been invested directly in the Funds  and the resulting reduction in  shareholder
servicing  costs. Although  these cost  savings are  not certain,  the estimated
savings to  the Funds  generated by  the  operation of  Global Trends  Fund  are
expected  to be sufficient to offset most,  if not all, of the expenses incurred
by that Fund.

Where      P          =          a hypothetical initial payment of $1,000.
           T          =          average annual total return (assuming the applicable maximum sales load is
                                 deducted at the beginning of the 1, 5, or 10 year periods).
           n          =          number of years.
           ERV        =          ending redeemable value of a hypothetical $1,000 payment at the end of the 1, 5,
                                 or 10 year periods (or fractional portion of such period).

Each Fund's investment results will vary from time to time depending upon market
conditions, the composition of each  Fund's portfolio and operating expenses  of
each  Fund,  so  that  current or  past  yield  or total  return  should  not be
considered representative of  what an investment  in each Fund  may earn in  any
future  period. These  factors and possible  differences in the  methods used in
calculating investment results should be  considered when comparing each  Fund's
investment results with those published for other investment companies and other
investment  vehicles. Each Fund's results also  should be considered relative to
the risks associated with such Fund's investment objective and policies.

which  can  be  expected  to  fluctuate.  The  Funds  may  provide   performance
information in reports, sales literature and advertisements. The Funds may also,
from  time to  time, quote  information about  the Funds  published or  aired by

largest holdings in  the Fund's  portfolio, (ii) certain  selling group  members
and/or (iii) certain institutional shareholders.
    
 
   
From time to time, the Funds' sales literature and/or advertisements may discuss
generic topics pertaining to the mutual fund industry. This includes, but is not

Although performance data may be useful to prospective investors when  comparing
a Fund's performance with other funds and other potential investments, investors
should  note  that  the  methods of  computing  performance  of  other potential
investments are not necessarily comparable to the methods employed by a Fund.

GENERAL INFORMATION ABOUT THE THEME FUNDS AND THEME PORTFOLIOS
Each  Theme  Portfolio  may  invest  worldwide  across  industries  within   the
Portfolio's area of concentration without national or regional restrictions. The
ability  of each  Theme Portfolio  to invest  worldwide may  allow the portfolio
managers to select industries in different economic cycles and varying stages of
development, though there is no assurance  that the managers will be  successful
in this selection.
 
Each  Theme Portfolio's area  of concentration reflects  the underlying theme of
the  Portfolio.  AIM  Distributors  believes  that  there  are  certain  social,
political  and economic trends that may benefit  one or more industries within a
Theme Portfolio's area of concentration. Of  course, there is no assurance  that
any of the Funds will benefit as a result.

INFORMATION ABOUT THE GLOBAL HEALTH CARE INDUSTRIES
The Fund and the Sub-adviser believe that certain market and demographic factors
merit  an  investor's  consideration  when  making  a  health  care  investment.
Worldwide   standards  of  living  and  life  expectancy  have  increased  at  a
substantial rate.  The  Sub-adviser expects  this  growth, which  works  to  the
general  benefit of the  global health care  industry, to continue  at a roughly
comparable rate  in the  future, although  no assurances  can be  given in  this
regard.  Moreover,  according  to  the  Sub-adviser,  the  health  care industry
historically has proven to be a relatively non-cyclical industry that  continues
to  provide goods and services to the  public in periods of economic weakness as
well as economic strength.
 
The Sub-adviser believes that  the anticipated increase  in the world's  elderly
population  could increase  demand for  health care  products and  services. For
example, according to data compiled by  the Sub-adviser, in Japan the number  of
people  age 65  and older is  expected to  grow over 100%  by the  year 2025; in
Germany, France and the U.S., the same age group should grow 40%. Similarly, the
U.S. Census Bureau predicts the  number of Americans 85  and older to double  in
the  next 30 years. From time to time,  the Fund and AIM Distributors will quote
information  including,  but  not  limited  to,  international  data   regarding
populations,   birth  rates,  mortality  rates,  life  expectancy,  health  care
expenditures, and gross  domestic product vs.  life expectancy. The  information
quoted  has not been independently verified by  the Fund or AIM Distributors and
will be based on data that is believed to be reliable and accurate.

data regarding:
 
    / / Increased usage  of  new  technologies  such as,  but  not  limited  to,
        cellular   and  wireless  communications  in  emerging  and  established
        countries around the world
 
    / / Supply and demand of telephone equipment and services
 
    / / Regulatory environment of telecommunications industries
 
    / / Revenue, price and usage of telecommunications products and services
 
    / / Privatization and/or deregulation of telecommunications companies
 
The information quoted has  not been independently verified  by the Fund or  AIM
Distributors  and will be based on data provided that is believed to be reliable
and accurate from sources including the following:
 
    / / Salomon Brothers World Equity  Telecommunications Index, which  includes
        stock  market data about the  telecommunications industry in established
        and developing markets
 
    / / OECD  and  other  publications  from   its  subsidiaries  such  as   the
        International Telecommunications Union
 
    / / Morgan  Stanley Capital International stock market industry indices such
        as Telecommunications, Broadcasting &  Publishing and Data Processing  &
        Reproduction
 
    / / International Technology Consultants, a Washington D.C. based firm which
        publishes  reports such as EASTERN EUROPEAN  & SOVIET TELECOM REPORT and
        LATIN AMERICAN TELECOM REPORT
 
    / / Telegeography and other publications
 
DEREGULATION IN THE UNITED STATES
The United States  has been  the bellwether  for deregulation  of the  telephone
industry.  The  divestiture  of  the Bell  System  from  American  Telephone and
Telegraph has  produced competing  companies  in the  United States.  Such  U.S.
market-driven  competition has,  for example, led  to lower  costs for consumers
which in turn led to greater consumer usage and to higher industrywide revenues.
The Sub-adviser expects this scenario to  continue to benefit such companies  in
the  U.S. and to similarly to  be realized by the established telecommunications
companies in established economies, although no  assurances can be made in  this
regard.
 
CONSUMER PRODUCTS AND SERVICES FUND
From time to time the Fund and AIM Distributors will quote information including

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from  "Aaa" to "C." Investment  grade ratings are the  first
four categories:
 
        Aaa  -- Bonds which are rated Aaa are  judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt  edged." Interest payments  are protected  by a large  or by  an
    exceptionally  stable  margin and  principal  is secure.  While  the various
    protective elements are likely to change, such changes as can be  visualized
    are  most  unlikely  to impair  the  fundamentally strong  position  of such
    issues.
 
        Aa -- Bonds which are rated Aa are  judged to be of high quality by  all
    standards.  Together with  the Aaa  group they  comprise what  are generally
    known as high grade bonds. They are rated lower than the best bonds  because
    margins  of  protection  may  not  be  as  large  as  in  Aaa  securities or
    fluctuation of protective elements may be of greater amplitude or there  may
    be  other elements  present which  make the  long-term risk  appear somewhat
    larger than the Aaa securities.
 
        A  --  Bonds  which  are  rated  A  possess  many  favorable  investment
    attributes  and  are  to be  considered  as  upper-medium-grade obligations.
    Factors giving security to principal  and interest are considered  adequate,
    but  elements may  be present which  suggest a  susceptibility to impairment
    some time in the future.
 
                  Statement of Additional Information Page 50
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
        Baa --  Bonds  which  are  rated  Baa  are  considered  as  medium-grade
    obligations,  (i.e., they are neither  highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective  elements may  be lacking  or may  be  characteristically
    unreliable  over  any  great length  of  time. Such  bonds  lack outstanding
    investment characteristics and in  fact have speculative characteristics  as
    well.
 
        Ba  -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered  as well-assured. Often the protection  of
    interest  and principal payments may be  very moderate, and thereby not well
    safeguarded during both good and bad  times over the future. Uncertainty  of
    position characterizes bonds in this class.
 
        B  --  Bonds which  are rated  B generally  lack characteristics  of the
    desirable investment. Assurance  of interest  and principal  payments or  of
    maintenance  of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa  are of poor standing. Such issues  may
    be  in default or  there may be  present elements of  danger with respect to
    principal or interest.
 
        Ca  --  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C  -- Bonds which are  rated C are the lowest  rated class of bonds, and
    issues so rated can be regarded  as having extremely poor prospects of  ever
    attaining any real investment standing.
 
ABSENCE  OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may  be for reasons unrelated  to the quality of  the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
         1. An application for rating was not received or accepted.
 
         2.  The issue or issuer  belongs to a group  of securities or companies
    that are not rated as a matter of policy.
 
         3. There is a lack of essential data pertaining to the issue or issuer.
 
         4. The issue  was privately  placed, in which  case the  rating is  not
    published in Moody's publications.
 
Suspension  or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data  to permit  a judgment  to be  formed; if  a bond  is
called for redemption; or for other reasons.
 
Note:  Moody's applies numerical  modifiers, 1, 2  and 3 in  each generic rating
classification from Aa to Caa. The  modifier 1 indicates that the Company  ranks
in  the higher end  of its generic  rating category; the  modifier 2 indicates a
mid-range ranking; and the  modifier 3 indicates that  the Company ranks in  the
lower end of its generic rating category.
 
    STANDARD  & POOR'S, a  division of The  McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various  entities in categories ranging from  "AAA"
to  "D"  according  to quality.  Investment  grade  ratings are  the  first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA  --  An  obligation  rated  "AA"  differs  from  the  highest   rated
    obligations  only  in a  small degree.  The obligor's  capacity to  meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB  --  An   obligation  rated  "BBB"   exhibits  adequate   protection
    parameters.  However, adverse economic  conditions or changing circumstances
    are more likely to lead  to a weakened capacity of  the obligor to meet  its
    financial commitment on the obligation.
 
        BB,  B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and "C"
    are  regarded  as  having  significant  speculative  characteristics.   "BB"
    indicates  the least degree  of speculation and "C"  the highest. While such
    obligations will likely  have some quality  and protective  characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB  -- An  obligation rated "BB"  is less vulnerable  to nonpayment than
    other speculative issues. However, it  faces major ongoing uncertainties  or
    exposure  to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate  capacity to meet its financial  commitment
    on the obligation.
 
                  Statement of Additional Information Page 51
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
        B  --  An obligation  rated "B"  is more  vulnerable to  nonpayment than
    obligations rated "BB," but the obligor  currently has the capacity to  meet
    its  financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to  nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for  the obligor to meet its financial  commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to  have the  capacity to meet  its financial  commitment on  the
    obligation.
 
        CC  --  An  obligation  rated "CC"  is  currently  highly  vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a  bankruptcy
    petition  has been filed or  similar action has been  taken, but payments on
    this obligation are being continued.
 
        D --  An obligation  rated "D"  is in  payment default.  The "D"  rating
    category is used when payments on an obligation are not made on the date due
    even  if the  applicable grace period  has not expired,  unless S&P believes
    that such payments  will be made  during such grace  period. The "D"  rating
    also  will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by  the
addition  of a  plus or minus  sign to  show relative standing  within the major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient  information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs  the  designation  "Prime-1" to  indicate  commercial  paper
having  a superior ability for repayment  of senior short-term debt obligations.
Prime-1 repayment  ability will  often be  evidenced by  many of  the  following
characteristics:  leading market positions  in well-established industries; high
rates of return  on funds employed;  conservative capitalization structure  with
moderate  reliance on debt and ample asset protection; broad margins in earnings
coverage of  fixed financial  charges  and high  internal cash  generation;  and
well-established  access to a range of  financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally  will be evidenced by many  of
the  characteristics cited  above but  to a  lesser degree.  Earnings trends and
coverage ratios, while sound, may  be more subject to variation.  Capitalization
characteristics,  while  still appropriate,  may  be more  affected  by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper  are graded into several categories  ranging
from  "A1" for the highest quality obligations  to "D" for the lowest. Issues in
the "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate  the
relative  degree  of safety.  A-1 --  This highest  category indicates  that the
degree of safety regarding timely payment is strong. Those issues determined  to
possess extremely strong safety characteristics will be denoted with a plus sign
(+)  designation.  A-2  -- Capacity  for  timely  payments on  issues  with this
designation is satisfactory; however,  the relative degree of  safety is not  as
high as for issues designated "A-1."

non-diversified series of AIM Investment Funds (the "Trust"), a registered open-
end management investment company organized as a Delaware business trust.
    
 
   
A  I  M  Advisors,  Inc.  ("AIM")  serves  as  the  investment  manager  of  and

administrator and sub-administrator, respectively, of the High Income Fund.
    
 
   
The Trust is  a series  mutual fund.  The rules  and regulations  of the  United
States  Securities and Exchange Commission (the  "SEC") require all mutual funds

information  required to be in this  Statement of Additional Information is also
included in the Prospectus, and, in order to avoid repetition, reference will be

Statement  of Additional Information  omit certain information  contained in the
Registration Statement filed with the SEC. Copies of the Registration Statement,
including items omitted  from the  Prospectus and this  Statement of  Additional
Information, may be obtained from the SEC by paying the charges prescribed under
its rules and regulations.
    
 
   
                      GENERAL INFORMATION ABOUT THE FUNDS
    
 
   
THE TRUST AND ITS SHARES
    
   
The  Trust previously operated under the name G.T. Investment Funds, Inc., which
was organized  as a  Maryland corporation  on October  29, 1987.  The Trust  was
reorganized on September 4, 1998 as a Delaware business trust, and is registered
with the SEC as a diversified open-end series management investment company. The
Trust  currently consists of thirteen separate portfolios: each of the six Theme
Funds, AIM  Global Government  Income Fund,  AIM Global  High Income  Fund,  AIM
Strategic  Income Fund, AIM Global Growth  and Income Fund, AIM Emerging Markets
Fund, AIM Developing Markets Fund, and  AIM Latin American Growth Fund. Each  of
these  funds has  three separate  classes: Class  A, Class  B and  Advisor Class
shares. All  historical  financial  and  other  information  contained  in  this
Statement  of Additional Information for periods  prior to September 4, 1998, is
that of the series of G.T. Investment Funds, Inc.
    
 
   
This Statement of Additional Information relates solely to the Class A and Class
B shares of the Funds.
    
 
   
The term "majority of the outstanding shares" of the Trust, of a particular Fund
or of a particular class of a  Fund means, respectively, the vote of the  lesser
of  (a) 67% or more of the shares of  the Trust, such Fund or such class present
at a meeting of the Trust's shareholders, if the holders of more than 50% of the
outstanding shares  of  the  Trust, such  Fund  or  such class  are  present  or
represented  by proxy,  or (b) more  than 50%  of the outstanding  shares of the
Trust, such Fund or such class.

                        AIM GLOBAL GROWTH & INCOME FUND
 
   
Class A, and Class B and Advisor Class shares of each Fund have equal rights and
privileges. Each  share  of a  particular  class is  entitled  to one  vote,  to
participate equally in dividends and distributions declared by the Trust's Board
of  Trustees with respect to the class of such Fund and, upon liquidation of the
Fund, to participate proportionately in the net assets of the Fund allocable  to
such  class remaining after satisfaction of  outstanding liabilities of the Fund
allocable to such class.  Fund shares are fully  paid, non-assessable and  fully
transferable  when issued and have no preemptive rights and have such conversion
and exchange  rights  as set  forth  in the  Prospectus  and this  Statement  of
Additional  Information. Fractional shares have proportionately the same rights,
including voting rights, as are provided for a full share.
    
 
   
Shareholders of the Funds  do not have cumulative  voting rights, and  therefore
the  holders of  more than  50% of  the outstanding  shares of  all Funds voting
together for election of directors may elect all of the members of the Board  of
Trustees  of the Trust.  In such event,  the remaining holders  cannot elect any
trustees of the Trust.

                       INVESTMENT OBJECTIVES AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES
   
The Government Income Fund primarily  seeks high current income and  secondarily
seeks capital appreciation and protection of principal through active management
of  the maturity structure and currency exposure of its portfolio. The Strategic
Income Fund and  the High  Income Fund primarily  seek high  current income  and
secondarily seek capital appreciation. The High Income Fund seeks to achieve its
investment  objectives  by  investing  all  of  its  investable  assets  in  the
Portfolio, which  is a  non-diversified open-end  management investment  company
with  investment objectives identical to those  of the Fund. Whenever the phrase
"all of the  High Income Fund's  investable assets"  is used herein  and in  the
Prospectus, it means that the only investment securities held by the High Income
Fund  will be its interest  in the Portfolio. The  High Income Fund may withdraw
its investment in the  Portfolio at any  time, if the Board  of Trustees of  the
Trust  determines  that  it  is  in  the best  interests  of  the  Fund  and its
shareholders to do so. Upon any  such withdrawal, the High Income Fund's  assets
would  be invested in  accordance with the investment  policies of the Portfolio
described below and in the Prospectus. The investment objective of the Growth  &
Income  Fund is long-term capital appreciation together with current income. The
Growth & Income Fund seeks its objective  by investing in a global portfolio  of
both   equity   securities  and   debt   obligations  allocated   among  diverse
international markets.
    
 
INVESTMENT IN EMERGING MARKETS
The Portfolio seeks its objectives by investing, under normal circumstances,  at
least 65% of its total assets in debt securities of issuers in emerging markets.
The  Strategic Income Fund may invest up to 50% of its assets in debt securities
of issuers in emerging markets. The  Strategic Income Fund and the Portfolio  do
not consider the following countries to be emerging markets: Australia, Austria,
Belgium,   Canada,  Denmark,   France,  Germany,  Ireland,   Italy,  Japan,  the
Netherlands, New Zealand,  Norway, Spain, Sweden,  Switzerland, United  Kingdom,
and United States.
 
In  addition to the  factors set forth  in the Prospectus,  the Sub-adviser will
also consider,  when determining  what  countries constitute  emerging  markets,
data, analysis, and classification of countries published or disseminated by the
International  Bank for  Reconstruction and  Development (commonly  known as the

SELECTION OF DEBT INVESTMENTS
   
In  determining  the  appropriate  distribution  of  investments  among  various
countries  and geographic regions for the  Government Income Fund, the Strategic
Income Fund,  the Growth  &  Income Fund,  and  the Portfolio,  the  Sub-adviser
ordinarily  considers  the following  factors:  prospects for  relative economic
growth among the different  countries in which the  Government Income Fund,  the
Strategic  Income Fund, the Growth & Income  Fund, and the Portfolio may invest;
expected  levels  of   inflation;  government   policies  influencing   business
conditions;  the  outlook  for  currency relationships;  and  the  range  of the
individual investment opportunities available to international investors.

                        AIM GLOBAL GROWTH & INCOME FUND
 
   
The Government Income  Fund, the  Strategic Income  Fund and  the Portfolio  may
invest   in  the  following  types  of  money  market  instruments  (i.e.,  debt
instruments with less than  12 months remaining  until maturity) denominated  in
U.S.  dollars or other  currencies: (a) obligations issued  or guaranteed by the
U.S.   or   foreign   governments,   their   agencies,   instrumentalities    or
municipalities;  (b)  obligations  of  international  organizations  designed or
supported  by  multiple  foreign  governmental  entities  to  promote   economic
reconstruction  or  development;  (c)  finance  company  obligations,  corporate
commercial  paper  and  other   short-term  commercial  obligations:  (d)   bank
obligations  (including certificates of deposit,  time deposits, demand deposits
and bankers' acceptances), subject to the restriction that the Government Income
Fund, the Strategic Income Fund and the  Portfolio may not invest more than  25%
of  their respective total assets in  bank securities; (e) repurchase agreements
with respect to the  foregoing; and (f)  other substantially similar  short-term
debt  securities with  comparable characteristics.  Money market  instruments in
which the Growth &  Income Fund may invest  include U.S. government  securities,
high-grade  commercial paper, bank certificates of deposit, bankers' acceptances
and  repurchase  agreements  related  to  any  of  the  foregoing.   "High-grade
commercial  paper" refers to commercial paper rated  A-1 by Standard & Poor's, a
division of The McGraw-Hill Companies, Inc. ("S&P"), or P-1 by Moody's Investors
Service, Inc. ("Moody's") or, if not rated, determined by the Sub-adviser to  be
of comparable quality.
    
 
   
SELECTION OF EQUITY INVESTMENTS
    
   
With  respect to  Growth &  Income Fund, for  investment purposes,  an issuer is
typically  considered  as  located  in  a  particular  country  if  it  (a)   is
incorporated  under the laws of or has  its principal office in that country, or
(b) it normally derives 50% or more  of its total revenue from business in  that
country.  However, these  are not  absolute requirements,  and certain companies
incorporated in a  particular country and  considered by the  Sub-adviser to  be
located   in  that  country   may  have  substantial   off-shore  operations  or
subsidiaries and/or export sales exceeding in  size the assets or sales in  that
country.
    
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
   
With  respect to certain  countries, investments by  the Government Income Fund,
the Strategic Income Fund, the Growth & Income Fund and the Portfolio  presently
may  be made only  by acquiring shares of  other investment companies (including
investment vehicles or companies  advised by the  Sub-adviser or its  affiliates
("Affiliated  Funds"))  with  local  governmental approval  to  invest  in those
countries. At such time as direct investment in these countries is allowed,  the
Government  Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio anticipate  investing directly  in these  markets. The  Government
Income  Fund,  the Strategic  Income  Fund, the  Growth  & Income  Fund  and the
Portfolio may also invest in  the securities of closed-end investment  companies
within  the limits  of the  Investment Company  Act of  1940, as  amended ("1940
Act"). These  limitations  currently  provide  that, in  part,  a  Fund  or  the
Portfolio  may purchase shares  of another investment company  unless (a) such a
purchase would cause the Government Income Fund, the Strategic Income Fund,  the
Growth  & Income Fund or the  Portfolio to own in the  aggregate more than 3% of
the total outstanding voting securities of the investment company or (b) such  a
purchase  would cause the Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund or the Portfolio to  have more than 5% of its total  assets
invested  in the  investment company  or more than  10% of  its aggregate assets
invested in  an  aggregate  of  all such  investment  companies.  The  foregoing
limitations  do  not apply  to the  investment by  the High  Income Fund  in the
Portfolio. Investment  in  investment  companies  may  involve  the  payment  of
substantial  premiums above the  value of such  companies' portfolio securities.
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the Portfolio do not intend to  invest in such investment companies unless,
in the judgment of the Sub-adviser,  the potential benefits of such  investments
justify  the payment of  any applicable premiums. The  return on such securities
will be reduced by  operating expenses of such  companies including payments  to
the   investment  managers  of  those  investment  companies.  With  respect  to
investments in Affiliated Funds, the Sub-adviser waives its advisory fee to  the
extent  that such  fees are  based on  assets of  a Fund  invested in Affiliated
Funds.
    
 
   
DEPOSITARY RECEIPTS
    
   
The Growth & Income Fund  may hold equity securities  of foreign issuers in  the
form  of  American  Depositary  Receipts  ("ADRs"),  American  Depositary Shares
("ADSs"), Global Depositary Receipts  ("GDRs") and European Depositary  Receipts
("EDRs"),  or other securities convertible  into securities of eligible issuers.
These securities may not necessarily be denominated in the same currency as  the
securities  for which they may be exchanged.  ADRs and ADSs typically are issued
by an  American bank  or  trust company  and  evidence ownership  of  underlying
securities  issued by a foreign corporation.  EDRs, which are sometimes referred
to as Continental Depositary Receipts  ("CDRs"), are issued in Europe  typically
by foreign banks and trust companies and evidence ownership of either foreign or
domestic  securities.  GDRs are  similar to  EDRs  and are  designed for  use in
several international financial markets. Generally, ADRs and ADSs in  registered
form

are designed for use in United States securities markets and EDRs in bearer form
are  designed for use in European securities markets. For purposes of the Fund's
investment policies, the Fund's investments in ADRs, ADSs, GDRs and EDRs will be
deemed to be  investments in  the equity securities  representing securities  of
foreign issuers into which they may be converted.
    
 
   
ADR  facilities may be established as either "unsponsored" or "sponsored." While
ADRs issued under these  two types of facilities  are in some respects  similar,
there  are distinctions between  them relating to the  rights and obligations of
ADR holders and the practices of market participants. A depository may establish
an unsponsored  facility  without  participation by  (or  even  necessarily  the
acquiescence  of) the issuer of the deposited securities, although typically the
depository requests a  letter of  non-objection from  such issuer  prior to  the
establishment  of the facility.  Holders of unsponsored  ADRs generally bear all
the costs  of such  facilities. The  depository usually  charges fees  upon  the
deposit  and withdrawal of the deposited securities, the conversion of dividends
into  U.S.  dollars,  the  disposition   of  non-cash  distributions,  and   the
performance  of  other  services.  The  depository  of  an  unsponsored facility
frequently is  under  no  obligation to  distribute  shareholder  communications
received  from the issuer of the  deposited securities or to pass-through voting
rights to ADR  holders in  respect of  the deposited  securities. Sponsored  ADR
facilities  are created in generally the  same manner as unsponsored facilities,
except that  the  issuer of  the  deposited  securities enters  into  a  deposit
agreement  with the  depository. The deposit  agreement sets out  the rights and
responsibilities of  the  issuer,  the  depository and  the  ADR  holders.  With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository),  although ADR holders continue to bear certain other costs (such as
deposit and withdrawal fees).  Under the terms  of most sponsored  arrangements,
depositories  agree  to distribute  notices of  shareholder meetings  and voting
instructions, and to provide shareholder communications and other information to
the ADR holders at the  request of the issuer  of the deposited securities.  The
Fund may invest in both sponsored and unsponsored ADRs.
    
 
SAMURAI AND YANKEE BONDS
The  Government Income  Fund, the  Strategic Income  Fund and  the Portfolio may
invest in yen-denominated bonds sold in Japan by non-Japanese issuers  ("Samurai
bonds"), and may invest in dollar-denominated bonds sold in the United States by
non-U.S.  issuers ("Yankee  bonds"). It is  the policy of  the Government Income
Fund, the Strategic Income Fund and the Portfolio to invest in Samurai or Yankee
bond issues  only  after  taking  into account  considerations  of  quality  and
liquidity, as well as yield.
 
WARRANTS OR RIGHTS
   
Warrants  or rights may be acquired by the Government Income Fund, the Strategic
Income Fund, the Growth & Income Fund or the Portfolio in connection with  other
securities  or separately and provide a Fund  or the Portfolio with the right to
purchase at a later date other securities of the issuer.
    
 
LENDING OF PORTFOLIO SECURITIES
   
For the purpose of realizing additional income, the Government Income Fund,  the
Strategic  Income  Fund, the  Growth &  Income  Fund or  the Portfolio  may make
secured loans of  portfolio securities  amounting to not  more than  30% of  its
total  assets.  Securities loans  are  made to  broker/dealers  or institutional
investors pursuant  to  agreements  requiring that  the  loans  continuously  be
secured by collateral at least equal at all times to the value of the securities
lent  plus  any accrued  interest,  "marked to  market"  on a  daily  basis. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund  and
the Portfolio may pay reasonable administrative and custodial fees in connection
with  loans of  its securities.  While the  securities loan  is outstanding, the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund  and
the  Portfolio  will  continue to  receive  the  equivalent of  the  interest or
dividends paid by  the issuer  on the  securities, as  well as  interest on  the
investment  of the collateral or a fee  from the borrower. The Government Income
Fund, the Strategic Income Fund, the Growth & Income Fund and the Portfolio each
will have a right to call each loan and obtain the securities within the  stated
settlement  period. The Government  Income Fund, the  Strategic Income Fund, the
Growth & Income Fund and  the Portfolio will not have  the right to vote  equity
securities  while they are lent, but each may  call in a loan in anticipation of
any important vote. Loans will be made  only to firms deemed by the  Sub-adviser
to  be of  good standing and  will not  be made unless,  in the  judgment of the
Sub-adviser, the consideration to  be earned from such  loans would justify  the
risk.

COMMERCIAL BANK OBLIGATIONS
   
For  the purposes of the Strategic Income Fund's, the Growth & Income Fund's and
the  Portfolio's  investment   policies  with  respect   to  bank   obligations,
obligations  of  foreign  branches  of  U.S.  banks  and  of  foreign  banks are
obligations of the  issuing bank and  may be general  obligations of the  parent
bank.  Such obligations,  however, may  be limited  by the  terms of  a specific
obligation  and  by  government  regulation.  As  with  investment  in  non-U.S.
securities  in general,  investments in the  obligations of  foreign branches of
U.S. banks  and of  foreign banks  may subject  the Strategic  Income Fund,  the
Growth & Income Fund and the Portfolio to investment risks that are different in
some  respects from  those of  investments in  obligations of  domestic issuers.
Although the Strategic Income Fund, the  Growth & Income Fund and the  Portfolio
typically will acquire obligations issued and supported by the credit of U.S. or
foreign  banks  having total  assets at  the time  of purchase  in excess  of $1
billion, this $1 billion  figure is not an  investment policy or restriction  of
the  Strategic Income Fund, the  Growth & Income Fund  or the Portfolio. For the
purposes of calculation with respect to the  $1 billion figure, the assets of  a
bank will be deemed to include the assets of its U.S. and non-U.S. branches.
    
 
REPURCHASE AGREEMENTS
   
A repurchase agreement is a transaction in which the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund or the Portfolio buys a security
from a bank or recognized securities dealer and simultaneously commits to resell
that  security to the  bank or dealer at  an agreed upon  price, date and market
rate of  interest unrelated  to the  coupon rate  or maturity  of the  purchased
security. Although repurchase agreements carry certain risks not associated with
direct investments in securities, including possible decline in the market value
of the underlying securities and delays and costs to the Government Income Fund,
the  Strategic Income Fund, the  Growth & Income Fund  or Portfolio if the other
party to the repurchase agreement becomes bankrupt, the Government Income  Fund,
the  Strategic Income Fund, the Growth & Income Fund and the Portfolio intend to
enter into repurchase agreements only with banks and broker/dealers believed  by
the  Sub-adviser to present  minimal credit risks  in accordance with guidelines
approved by the Trust's  or the Portfolio's Board  of Trustees. The  Sub-adviser
reviews and monitors the creditworthiness of such institutions under the Board's
general supervision.
    
 
   
The  Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio will  invest only in  repurchase agreements collateralized  at
all  times in  an amount  at least  equal to  the repurchase  price plus accrued
interest. To the extent that the proceeds from any sale of such collateral  upon
a  default in the obligation to repurchase  were less than the repurchase price,
the Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
or  the Portfolio  would suffer  a loss. If  the financial  institution which is
party to the repurchase agreement petitions for bankruptcy or otherwise  becomes
subject to bankruptcy or other liquidation proceedings there may be restrictions
on  the Government Income Fund,  the Strategic Income Fund,  the Growth & Income
Fund's or the  Portfolio's ability  to sell  the collateral  and the  Government
Income  Fund,  the  Strategic Income  Fund,  the  Growth &  Income  Fund  or the
Portfolio could suffer a loss.  However, with respect to financial  institutions
whose  bankruptcy or liquidation proceedings are  subject to the U.S. Bankruptcy
Code, the Government Income Fund, the Strategic Income Fund, the Growth & Income
Fund and the  Portfolio intend to  comply with provisions  under such Code  that
would  allow the immediate resale of such collateral. The Government Income Fund
and the Growth & Income Fund will  not enter into a repurchase agreement with  a
maturity  of more than seven days if, as a result, more than 10% of the value of
each Fund's total  assets would be  invested in such  repurchase agreements  and
other  illiquid investments and securities for which no readily available market
exists. There is  no limitation  on the  amount of  the Growth  & Income  Fund's
assets that may be subject to repurchase agreements at any time.
    
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
   
The  Government Income Fund's, the Strategic  Income Fund's, the Growth & Income
Fund's and the Portfolio's borrowings will not  exceed 33 1/3% of the Fund's  or
the  Portfolio's respective total assets, i.e.,  the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund's or the Portfolio's  respective
total  assets at all times will equal at least 300% of the amount of outstanding
borrowings. If market fluctuations in the value of the Government Income Fund's,
the Strategic  Income Fund's,  the Growth  & Income  Fund's or  the  Portfolio's
holdings  or other factors cause the ratio  of the Government Income Fund's, the
Strategic Income Fund's,  the Growth &  Income Fund's or  the Portfolio's  total
assets  to  outstanding  borrowings  to  fall  below  300%,  within  three  days
(excluding Sundays  and holidays)  of  such event  the  respective Fund  or  the
Portfolio may be required to sell portfolio securities to restore the 300% asset
coverage,  even  though  from  an  investment  standpoint  such  sales  might be
disadvantageous. The  Government Income  Fund, the  Strategic Income  Fund,  the
Growth  &  Income  Fund and  the  Portfolio each  may  borrow  up to  5%  of its
respective total assets for

temporary or emergency purposes other than to meet redemptions. Any borrowing by
the Government Income Fund, the Strategic  Income Fund the Growth & Income  Fund
or  the Portfolio may cause greater fluctuation  in the value of its shares than
would be the case if the Fund or the Portfolio did not borrow.
    
 
   
The Government Income Fund's, the Strategic  Income Fund's, the Growth &  Income
Fund's  and the  Portfolio's fundamental  investment limitations  permit them to
borrow money for leveraging purposes. The Government Income Fund and the  Growth
&  Income Fund, however, currently are prohibited, pursuant to a non-fundamental
investment policy,  from  borrowing  money  in  order  to  purchase  securities.
Nevertheless,  this policy may be changed in the  future by a vote of a majority
of the Trust's Board  of Trustees. The Strategic  Income Fund and the  Portfolio
may  borrow  for  leveraging  purposes.  If the  Strategic  Income  Fund  or the
Portfolio employs leverage, it would be subject to certain additional risks. Use
of leverage  creates an  opportunity for  greater growth  of capital  but  would
exaggerate  any increases  or decreases  in the  Strategic Income  Fund's or the
Portfolio's net asset value. When the  income and gains on securities  purchased
with  the  proceeds  of borrowings  exceed  the  costs of  such  borrowings, the
Government Income  Fund's, the  Strategic  Income Fund's,  the Growth  &  Income
Fund's  or the Portfolio's earnings or net asset value will increase faster than
otherwise would be the case; conversely, if such income and gains fail to exceed
such costs, the  Fund's or  the Portfolio's earnings  or net  asset value  would
decline faster than would otherwise be the case.
    
 
   
The  Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the  Portfolio  may enter  into  reverse repurchase  agreements.  A  reverse
repurchase  agreement is a borrowing transaction  in which the Government Income
Fund, the  Strategic Income  Fund, the  Growth &  Income Fund  or the  Portfolio
transfers  possession  of  a  security  to another  party,  such  as  a  bank or
broker/dealer, in return for cash, and agrees to repurchase the security in  the
future  at  an agreed  upon  price, which  includes  an interest  component. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund  and
the Portfolio also may engage in "roll" borrowing transactions which involve the
Government  Income  Fund's, the  Strategic Income  Fund's,  the Growth  & Income
Fund's or  the  Portfolio's sale  of  Government National  Mortgage  Association
certificates  or  other securities  together with  a  commitment (for  which the
Government Income Fund, the Strategic Income  Fund, the Growth & Income Fund  or
the  Portfolio  may  receive a  fee)  to  purchase similar,  but  not identical,
securities at a future  date. The Government Income  Fund, the Strategic  Income
Fund,  the  Growth  &  Income  Fund and  the  Portfolio  will  segregate  with a
custodian, cash  or liquid  securities  in an  amount  sufficient to  cover  its
obligations  under "roll"  transactions and  reverse repurchase  agreements with
broker/dealers. No  segregation is  required for  reverse repurchase  agreements
with banks.
    
 
SHORT SALES
   
The  Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio  may make  short sales of  securities, although  they have  no
current  intention of doing so. A short sale is a transaction in which a Fund or
the Portfolio sells  a security in  anticipation that the  market price of  that
security  will decline. The  Government Income Fund,  the Strategic Income Fund,
the Growth & Income  Fund and the Portfolio  may make short sales  as a form  of
hedging to offset potential declines in long positions in securities it owns, or
anticipates  acquiring,  and in  order  to maintain  portfolio  flexibility. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund  and
the Portfolio only may make short sales "against the box." In this type of short
sale,  at the time of the  sale, the Fund or the  Portfolio owns the security it
has sold  short or  has the  immediate and  unconditional right  to acquire  the
identical security at no additional cost.
    
 
   
In a short sale, the seller does not immediately deliver the securities sold and
does  not receive the proceeds from the sale. To make delivery to the purchaser,
the executing broker borrows  the securities being sold  short on behalf of  the
seller. The seller is said to have a short position in the securities sold until
it  delivers the securities sold, at which  time it receives the proceeds of the
sale. To secure its obligation to deliver securities sold short, the  Government
Income  Fund,  the  Strategic Income  Fund,  the  Growth &  Income  Fund  or the
Portfolio will deposit in a separate account with its custodian an equal  amount
of  the securities sold short or securities convertible into or exchangeable for
such securities at  no cost. The  Government Income Fund,  the Strategic  Income
Fund, the Growth & Income Fund or the Portfolio could close out a short position
by  purchasing  and delivering  an equal  amount of  the securities  sold short,
rather than by delivering securities already held by the Fund or the  Portfolio,
because the Fund or the Portfolio might want to continue to receive interest and
dividend  payments on securities in its  portfolio that are convertible into the
securities sold short.
    
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the Portfolio might make  a short sale "against the  box" in order to hedge
against market  risks  when  the  Sub-adviser  believes  that  the  price  of  a

security  may decline, causing a decline in the value of a security owned by the
Government Income Fund, the Strategic Income  Fund, the Growth & Income Fund  or
the  Portfolio or a security convertible into or exchangeable for such security.
In such case, any future losses  in the Government Income Fund's, the  Strategic
Income  Fund's,  the Growth  & Income  Fund's or  the Portfolio's  long position
should be reduced by a gain in  the short position. Conversely, any gain in  the
long  position should be reduced by a loss  in the short position. The extent to
which such gains or losses in the long position are reduced will depend upon the
amount of the securities sold short relative to the amount of the securities the
Fund or the  Portfolio owns,  either directly or  indirectly, and,  in the  case
where  a  Fund or  the  Portfolio owns  convertible  securities, changes  in the
investment values  or conversion  premiums  of such  securities. There  will  be
certain  additional transaction costs  associated with short  sales "against the
box," but a  Fund or  the Portfolio  will endeavor  to offset  these costs  with
income from the investment of the cash proceeds of short sales.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use of options, futures contracts  and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1) Successful  use  of  most  of these  instruments  depends  upon  the
    Sub-adviser's  ability to  predict movements  of the  overall securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-adviser is experienced in
    the use of these instruments, there can be no assurance that any  particular
    strategy adopted will succeed.
 
        (2)  There  might  be  imperfect correlation,  or  even  no correlation,
    between price  movements  of  an  instrument  and  price  movements  of  the
    investments being hedged. For example, if the value of an instrument used in
    a  short hedge  increased by less  than the  decline in value  of the hedged
    investment, the  hedge  would  not  be fully  successful.  Such  a  lack  of
    correlation  might  occur  due to  factors  unrelated  to the  value  of the
    investments being  hedged, such  as speculative  or other  pressures on  the
    markets  in which  the hedging  instrument is  traded. The  effectiveness of
    hedges using hedging  instruments on indices  will depend on  the degree  of
    correlation  between price movements in the index and price movements in the
    investments being hedged.
 
   
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative  effect of unfavorable price  movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity  for gain by  offsetting the positive  effect of favorable price
    movements in the hedged investments.  For example, if the Government  Income
    Fund,  the Strategic Income Fund, the Growth  & Income Fund or the Portfolio
    entered into a short  hedge because the Sub-adviser  projected a decline  in
    the  price of a security in the Fund's or the Portfolio's portfolio, and the
    price of that security increased instead, the gain from that increase  might
    by  wholly or  partially offset  by a  decline in  the price  of the hedging
    instrument. Moreover, if  the price  of the hedging  instrument declined  by
    more  than the increase in the price  of the security, the Government Income
    Fund, the Strategic Income Fund, the  Growth & Income Fund or the  Portfolio
    could  suffer a loss. In  either such case, the  Government Income Fund, the
    Strategic Income Fund, the Growth & Income Fund or the Portfolio would  have
    been in a better position had it not hedged at all.
    
 
   
        (4) As described below, the Government Income Fund, the Strategic Income
    Fund,  the  Growth &  Income  Fund or  the  Portfolio might  be  required to
    maintain assets  as "cover,"  maintain segregated  accounts or  make  margin
    payments  when it  takes positions  in instruments  involving obligations to
    third parties (I.E., instruments other than purchased options). If a Fund or
    the Portfolio were unable to close out its positions in such instruments, it
    might be required to  continue to maintain such  assets or accounts or  make
    such  payments until the position expired or matured. The requirements might
    impair the Fund's  ability or the  Portfolio's ability to  sell a  portfolio
    security  or  make  an investment  at  a  time when  it  would  otherwise be
    favorable to  do so,  or  require that  the Fund  or  the Portfolio  sell  a

    portfolio  security at a disadvantageous time. The Fund's or the Portfolio's
    ability to close  out a  position in an  instrument prior  to expiration  or
    maturity  depends on the existence  of a liquid secondary  market or, in the
    absence of such a market, the ability and willingness of the other party  to
    the transaction ("contra party") to enter into a transaction closing out the
    position.  Therefore, there is no assurance  that any position can be closed
    out at a time and price that is favorable to the Fund or the Portfolio.
 
WRITING CALL OPTIONS
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the  Portfolio may  write (sell)  call options  on securities,  indices and
currencies. Call options generally will be written on securities and  currencies
that, in the opinion of the Sub-adviser are not expected to make any major price
moves  in  the near  future  but that,  over  the long  term,  are deemed  to be
attractive investments  for the  Government Income  Fund, the  Strategic  Income
Fund, the Growth & Income Fund and the Portfolio.
    
 
A  call option  gives the  holder (buyer)  the right  to purchase  a security or
currency at a specified price (the  exercise price) at any time until  (American
Style)  or on (European Style) a certain  date (the expiration date). So long as
the obligation of the writer of a  call option continues, he may be assigned  an
exercise  notice, requiring him  to deliver the  underlying security or currency
against payment  of the  exercise  price. This  obligation terminates  upon  the
expiration  of the call option, or such earlier time at which the writer effects
a closing  purchase  transaction  by  purchasing an  option  identical  to  that
previously sold.
 
   
Portfolio  securities or currencies on which call options may be written will be
purchased solely on  the basis  of investment considerations  consistent with  a
Fund's or the Portfolio's investment objectives. When writing a call option, the
Government  Income Fund, the Strategic Income Fund,  the Growth & Income Fund or
the Portfolio, in return  for the premium, gives  up the opportunity for  profit
from  a price increase in the underlying security or currency above the exercise
price, and retains the risk of loss should the price of the security or currency
decline. Unlike one who owns securities or currencies not subject to an  option,
a  Fund or the Portfolio has no control over when it may be required to sell the
underlying securities or currencies, since most options may be exercised at  any
time  prior to  the option's  expiration. If a  call option  that a  Fund or the
Portfolio has written expires, the Fund or the Portfolio will realize a gain  in
the  amount of the premium; however, such gain may be offset by a decline in the
market value of the underlying security or currency during the option period. If
the call option is exercised, the Fund  or the Portfolio will realize a gain  or
loss  from  the sale  of  the underlying  security  or currency,  which  will be
increased or offset  by the premium  received. The Government  Income Fund,  the
Strategic  Income  Fund, the  Growth  & Income  Fund  and the  Portfolio  do not
consider a security or currency covered by a call option to be "pledged" as that
term is used in the Government  Income Fund's, the Strategic Income Fund's,  the
Growth  & Income Fund's and the Portfolio's fundamental investment policies that
limit the pledging or mortgaging of their assets.
    
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option will be exercised  and a Fund or the Portfolio will
be obligated to sell the security or currency at less than its market value.
 
   
The premium that  the Government  Income Fund,  the Strategic  Income Fund,  the
Growth  & Income  Fund or the  Portfolio receives  for writing a  call option is
deemed to constitute the market  value of an option. The  premium a Fund or  the
Portfolio  will receive  from writing  a call  option will  reflect, among other
things, the current market price of the underlying investment, the  relationship
of  the exercise price to such market  price, the historical price volatility of
the underlying investment, and the length  of the option period. In  determining
whether  a  particular  call  option should  be  written,  the  Sub-adviser will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
    
 
   
Closing transactions  will  be effected  in  order to  realize  a profit  on  an
outstanding  call option,  to prevent  an underlying  security or  currency from
being called, or  to permit  the sale of  the underlying  security or  currency.
Furthermore,  effecting a closing transaction  will permit the Government Income
Fund, the Strategic Income Fund,  the Growth & Income  Fund or the Portfolio  to
write  another call option on the underlying  security or currency with either a
different exercise price, expiration date or both.

The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the Portfolio will pay transaction costs  in connection with the writing of
options and  in  entering into  closing  purchase contracts.  Transaction  costs
relating  to  options  activity normally  are  higher than  those  applicable to
purchases and sales of portfolio securities.
    
 
The exercise price of the  options may be below, equal  to or above the  current
market values of the underlying securities or currencies at the time the options
are  written.  From  time to  time,  a Fund  or  the Portfolio  may  purchase an
underlying security or currency for delivery in accordance with the exercise  of
an  option, rather than delivering such security or currency from its portfolio.
In such cases, additional costs will be incurred.
 
A Fund or the Portfolio  will realize a profit or  loss from a closing  purchase
transaction  if the cost of the transaction  is less or more, respectively, than
the premium received from  writing the option. Because  increases in the  market
price  of a call option generally will  reflect increases in the market price of
the underlying security or currency, any loss resulting from the repurchase of a
call option is likely to  be offset in whole or  in part by appreciation of  the
underlying security or currency owned by a Fund or the Portfolio.
 
WRITING PUT OPTIONS
   
The  Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio may write put options on securities, indices and currencies. A
put option gives the purchaser of the  option the right to sell, and the  writer
(seller)  the  obligation to  buy, the  underlying security  or currency  at the
exercise price at  anytime until  (American Style)  or on  (European Style)  the
expiration date. The operation of put options in other respects, including their
related risks and rewards, is substantially identical to that of call options.
    
 
A Fund or the Portfolio generally would write put options in circumstances where
the  Sub-adviser wishes to purchase the  underlying security or currency for the
Fund's or the  Portfolio's portfolio at  a price lower  than the current  market
price  of the  security or currency.  In such  event, the Fund  or the Portfolio
would write a  put option  at an  exercise price  that, reduced  by the  premium
received on the option, reflects the lower price it is willing to pay. Since the
Fund  or  the  Portfolio  also  would receive  interest  on  debt  securities or
currencies maintained to cover the exercise price of the option, this  technique
could  be used to  enhance current return during  periods of market uncertainty.
The risk in such a transaction would be that the market price of the  underlying
security  or currency  would decline below  the exercise price  less the premium
received.
 
Writing put options can serve as a  limited long hedge because increases in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
depreciates  to a price lower than the exercise  price of the put option, it can
be expected that the put  option will be exercised and  a Fund or the  Portfolio
will  be obligated  to purchase  the security  or currency  at greater  than its
market value.
 
PURCHASING PUT OPTIONS
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and   the  Portfolio  may  purchase  put  options  on  securities,  indices  and
currencies. As  the holder  of a  put option,  the Government  Income Fund,  the
Strategic  Income Fund, the Growth & Income Fund or the Portfolio would have the
right to sell the underlying security or  currency at the exercise price at  any
time  until  (American Style  or on  (European Style)  the expiration  date. The
Government Income Fund, the Strategic Income  Fund, the Growth & Income Fund  or
the  Portfolio may  enter into  closing sale  transactions with  respect to such
options, exercise them or permit them to expire.
    
 
A Fund or the Portfolio may purchase  a put option on an underlying security  or
currency  ("protective put")  owned by  the Fund or  the Portfolio  as a hedging
technique in order to protect against an anticipated decline in the value of the
security or currency. Such hedge protection is provided only during the life  of
the  put option when the Fund or the Portfolio, as the holder of the put option,
is able to sell the  underlying security or currency  at the put exercise  price
regardless  of  any  decline  in  the  underlying  security's  market  price  or
currency's exchange  value.  The  premium  paid  for  the  put  option  and  any
transaction  costs would reduce any  profit otherwise available for distribution
when the security or currency eventually is sold.
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the Portfolio also may purchase put options at a time when that Fund or the
Portfolio does not own  the underlying security or  currency. By purchasing  put
options on a security or currency it does not own, a Fund or the Portfolio seeks
to  benefit from  a decline in  the market  price of the  underlying security or
currency. If the put option is not sold when it has remaining value, and if  the
market  price of the underlying security or currency remains equal to or greater
than the exercise  price during  the life  of the put  option, the  Fund or  the
Portfolio  will lose its entire  investment in the put  option. In order for the
purchase of a put

option to be profitable, the market price of the underlying security or currency
must decline sufficiently  below the  exercise price  to cover  the premium  and
transaction costs, unless the put option is sold in a closing sale transaction.
 
PURCHASING CALL OPTIONS
   
The  Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
or  the  Portfolio  may  purchase  call  options  on  securities,  indices   and
currencies.  As the holder of a call option,  a Fund or the Portfolio would have
the right to purchase the underlying security or currency at the exercise  price
at any time until (American Style) or on (European Style) the expiration date. A
Fund  or the Portfolio may enter into  closing sale transactions with respect to
such options, exercise them or permit them to expire.
    
 
Call options may  be purchased by  a Fund or  the Portfolio for  the purpose  of
acquiring  the underlying  security or currency  for its  portfolio. Utilized in
this fashion,  the  purchase  of call  options  would  enable the  Fund  or  the
Portfolio  to acquire the security or currency at the exercise price of the call
option plus the premium paid. At times,  the net cost of acquiring the  security
or  currency in this manner may be less  than the cost of acquiring the security
or currency  directly. This  technique  also may  be useful  to  a Fund  or  the
Portfolio in purchasing a large block of securities that would be more difficult
to  acquire by direct market purchases. So long  as it holds such a call option,
rather than the underlying security or currency itself, a Fund or the  Portfolio
is  partially protected from any  unexpected decline in the  market price of the
underlying security or currency and, in such event, could allow the call  option
to  expire, incurring  a loss  only to the  extent of  the premium  paid for the
option.
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the Portfolio  also may purchase  call options on  underlying securities or
currencies it owns to avoid realizing losses that would result in a reduction of
a Fund's or the  Portfolio's current return.  For example, where  a Fund or  the
Portfolio has written a call option on an underlying security or currency having
a  current market value  below the price  at which it  purchased the security or
currency, an increase in the  market price could result  in the exercise of  the
call  option written by the Fund or the  Portfolio and the realization of a loss
on the underlying security or currency.  Accordingly, the Fund or the  Portfolio
could  purchase a call option on the same underlying security or currency, which
could be exercised to fulfill the Fund's or the Portfolio's delivery obligations
under its written call (if it is exercised). This strategy could allow the  Fund
or  the Portfolio to avoid selling the  portfolio security or currency at a time
when it has an unrealized loss; however, the Fund or the Portfolio would have to
pay a premium to purchase the call option plus transaction costs.
    
 
   
Aggregate premiums paid  for put  and call  options will  not exceed  5% of  the
Government  Income  Fund's, the  Strategic Income  Fund's,  the Growth  & Income
Fund's or the Portfolio's total assets at the time of purchase.
    
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
or  the Portfolio may attempt to accomplish objectives similar to those involved
in using Forward Contracts  by purchasing put or  call options on currencies.  A
put  option gives a  Fund or the Portfolio  as purchaser the  right (but not the
obligation) to sell a specified amount of currency at the exercise price at  any
time until (American Style) or on (European Style) the expiration of the option.
A  call option gives a Fund or the Portfolio as purchaser the right (but not the
obligation) to purchase a specified amount of currency at the exercise price  at
any  time until (American  Style) or on  (European Style) the  expiration of the
option. A  Fund or  the Portfolio  might  purchase a  currency put  option,  for
example,  to protect itself against a decline  in the dollar value of a currency
in which it  holds or anticipates  holding securities. If  the currency's  value
should  decline against the dollar, the loss in currency value should be offset,
in whole or in part, by an increase in the value of the put. If the value of the
currency instead should rise  against the dollar,  any gain to  the Fund or  the
Portfolio  would be  reduced by the  premium it had  paid for the  put option. A
currency call option might be purchased, for example, in anticipation of, or  to
protect  against, a rise in the value against  the dollar of a currency in which
the Fund or the Portfolio anticipates purchasing securities.
    
 
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing corporation), and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates.  The Funds and the  Portfolio will not purchase  an OTC option unless the
Fund or  the Portfolio  believes  that daily  valuations  for such  options  are
readily  obtainable. OTC options differ from exchange-traded options in that OTC
options are  transacted  with  dealers  directly  and  not  through  a  clearing
corporation  (which guarantees  performance). Consequently,  there is  a risk of
non-performance by the dealer.  Since no exchange is  involved, OTC options  are
valued on the basis of the average of the last bid prices obtained from dealers,
unless a

quotation  from only one dealer  is available, in which  case only that dealer's
price will be used. In the case of OTC options, there can be no assurance that a
liquid secondary market  will exist for  any particular option  at any  specific
time.
 
   
The  staff of the SEC considers purchased OTC options to be illiquid securities.
A Fund or the Portfolio may also sell OTC options and, in connection  therewith,
segregate assets or cover its obligations with respect to OTC options written by
the Fund or the Portfolio. The assets used as cover for OTC options written by a
Fund  or the Portfolio  will be considered  illiquid unless the  OTC options are
sold to  qualified  dealers  who  agree  that the  Fund  or  the  Portfolio  may
repurchase  any OTC option  it writes at a  maximum price to  be calculated by a
formula set forth in the option agreement.  The cover for an OTC option  written
subject  to this procedure would be considered  illiquid only to the extent that
the maximum repurchase price  under the formula exceeds  the intrinsic value  of
the option.
    
 
A  Fund's or  the Portfolio's  ability to establish  and close  out positions in
exchange-listed options depends on the existence  of a liquid market. Each  Fund
and  the  Portfolio  intends to  purchase  or write  only  those exchange-traded
options for which there appears to be a liquid secondary market. However,  there
can  be  no assurance  that such  a market  will exist  at any  particular time.
Closing transactions can be  made for OTC options  only by negotiating  directly
with  the contra party or  by a transaction in the  secondary market if any such
market exists. Although each Fund and the Portfolio will enter into OTC  options
only  with  contra parties  that are  expected  to be  capable of  entering into
closing transactions with the Fund or the Portfolio, there is no assurance  that
the  Fund or  the Portfolio  will in  fact be  able to  close out  an OTC option
position at a favorable price prior  to expiration. In the extent of  insolvency
of  the contra party, the Fund or the  Portfolio might be unable to close out an
OTC option position at any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts except that all settlements  are in cash and  gain or loss depends  on
changes  in the index in question (and thus on price movements in the securities
market or a particular market sector  generally) rather than on price  movements
in  individual securities  or futures  contracts. When  a Fund  or the Portfolio
writes a call on an index, it receives  a premium and agrees that, prior to  the
expiration  date, the  purchaser of  the call, upon  exercise of  the call, will
receive from the Fund or the Portfolio an amount of cash if the closing level of
the index upon which the call is based is greater than the exercise price of the
call. The amount of cash is equal to the difference between the closing price of
the index and the  exercise price of  the call times  a specified multiple  (the
"multiplier"),  which determines the  total dollar value for  each point of such
difference. When a  Fund or the  Portfolio buys a  call on an  index, it pays  a
premium  and has the same rights as to  such call as are indicated above. When a
Fund or the Portfolio  buys a put  on an index,  it pays a  premium and has  the
right,  prior to the expiration date, to require the seller of the put, upon the
Fund's or the Portfolio's  exercise of the  put, to deliver to  the Fund or  the
Portfolio an amount of cash if the closing level of the index upon which the put
is  based is less  than the exercise price  of the put, which  amount of cash is
determined by the multiplier, as described above  for calls. When a Fund or  the
Portfolio  writes a put on an index, it receives a premium and the purchaser has
the right, prior to the expiration date, to require the Fund or the Portfolio to
deliver to it  an amount of  cash equal  to the difference  between the  closing
level  of the index and the exercise  price times the multiplier, if the closing
level is less than the exercise price.
 
The risks  of  investment  in index  options  may  be greater  than  options  on
securities.  Because  index options  are settled  in  cash, when  a Fund  or the
Portfolio writes  a call  on  an index  it cannot  provide  in advance  for  its
potential  settlement  obligations  by  acquiring  and  holding  the  underlying
securities. A Fund or  the Portfolio can  offset some of the  risk of writing  a
call  index option  position by  holding a  diversified portfolio  of securities
similar to those on which the underlying index is based. However, a Fund or  the
Portfolio cannot, as a practical matter, acquire and hold a portfolio containing
exactly the same securities as underlie the index and, as a result, bears a risk
that the value of the securities held will vary from the value of the index.
 
Even  if a  Fund or  the Portfolio  could assemble  a securities  portfolio that
exactly reproduced the composition of the  underlying index, it still would  not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing  index options. When  an index option  is exercised, the  amount of cash
that the holder is entitled to  receive is determined by the difference  between
the  exercise price and the  closing index level on the  date when the option is
exercised. As with other  kinds of options,  the Fund or  the Portfolio, as  the
call writer, will not know that it has been assigned until the next business day
at the earliest. The time lag between exercise and notice of assignment poses no
risk for the writer of a covered call on a specific underlying security, such as
common stock, because there the writer's obligation is to deliver the underlying
security,  not to pay its value  as of a fixed time in  the past. So long as the
writer already owns the underlying

security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value  may have declined since the  exercise date is borne  by
the  exercising holder. In contrast,  even if the writer  of an index call holds
securities that exactly match the composition  of the underlying index, it  will
not be able to satisfy its assignment obligations by delivering those securities
against  payment of the exercise price. Instead, it will be required to pay cash
in an amount based on the closing index  value on the exercise date; and by  the
time  it learns that it  has been assigned, the index  may have declined, with a
corresponding decline in  the value  of its securities  portfolio. This  "timing
risk"  is an inherent limitation  on the ability of  index call writers to cover
their risk exposure by holding securities positions.
 
If a Fund or the Portfolio purchases an index option and exercises it before the
closing index value for that day is  available, it runs the risk that the  level
of  the underlying index  may subsequently change.  If such a  change causes the
exercised option to  fall out-of-the-money, the  Fund or the  Portfolio will  be
required  to pay the difference between the closing index value and the exercise
price of the option (times the applicable multiplier) to the assigned writer.
 
   
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
    
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
or  the Portfolio  may enter  into interest  rate or  currency futures contracts
("Futures" or  "Futures Contracts")  as a  hedge against  changes in  prevailing
levels  of interest rates or currency exchange  rates in order to establish more
definitely the effective return on securities or currencies held or intended  to
be  acquired by  the Fund  or the Portfolio.  The Government  Income Fund's, the
Strategic Income Fund's, the Growth &  Income Fund's or the Portfolio's  hedging
may  include  sales of  Futures  as an  offset  against the  effect  of expected
increases in  interest  rates  or  decreases in  currency  exchange  rates,  and
purchases  of Futures as  an offset against  the effect of  expected declines in
interest rates or increases in currency exchange rates. The Growth & Income Fund
may also enter into stock index Futures Contracts as a hedge against changes  in
stock  prices and the Government Income Fund,  the Strategic Income Fund and the
Portfolio may enter into Futures Contracts on indices of debt securities.
    
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the Portfolio  only will  enter into Futures  Contracts that  are traded on
futures exchanges  and  are standardized  as  to maturity  date  and  underlying
financial instrument. Futures exchanges and trading thereon in the United States
are  regulated under the Commodity Exchange Act by the Commodity Futures Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
    
 
Although techniques other than sales and purchases of Futures Contracts could be
used to  reduce  a Fund's  or  the Portfolio's  exposure  to interest  rate  and
currency  exchange rate  fluctuations, a  Fund or the  Portfolio may  be able to
hedge exposure  more effectively  and  at a  lower  cost through  using  Futures
Contracts.
 
A  Futures Contract provides  for the future  sale by one  party and purchase by
another party of  a specified amount  of a specific  financial instrument  (debt
security  or currency)  for a  specified price  at a  designated date,  time and
place. An index  Futures Contract  provides for  the delivery,  at a  designated
date,  time and place, of  an amount of cash equal  to a specified dollar amount
times the difference  between the index  value at  the close of  trading on  the
contract  and the price at  which the Futures Contract  is originally struck; no
physical delivery of the securities comprising the index is made. Brokerage fees
are incurred when a Futures Contract is bought or sold, and margin deposits must
be maintained at all times the Futures Contract is outstanding.
 
   
Although Futures Contracts typically require future delivery of and payment  for
financial  instruments or currencies,  Futures Contracts usually  are closed out
before the delivery date. Closing out an open Futures Contract sale or  purchase
is  effected by entering  into an offsetting Futures  Contract purchase or sale,
respectively,  for  the  same  aggregate  amount  of  the  identical   financial
instrument  or currency and  the same delivery date.  If the offsetting purchase
price is less  than the  original sale price,  the Government  Income Fund,  the
Strategic  Income Fund,  the Growth  & Income Fund  or the  Portfolio realizes a
gain; if it is more, the Government Income Fund, the Strategic Income Fund,  the
Growth  &  Income Fund  or the  Portfolio  realizes a  loss. Conversely,  if the
offsetting sale price is more than  the original purchase price, the  Government
Income  Fund,  the  Strategic Income  Fund,  the  Growth &  Income  Fund  or the
Portfolio realizes  a gain;  if it  is  less, the  Government Income  Fund,  the
Strategic  Income Fund,  the Growth  & Income Fund  or the  Portfolio realizes a
loss. The transaction costs also must  be included in these calculations.  There
can be no assurance, however, that a Fund or the Portfolio will be able to enter
into  an offsetting transaction with respect to a particular Futures Contract at
a particular time.  If a  Fund or the  Portfolio is  not able to  enter into  an
offsetting  transaction, the Fund or the  Portfolio will continue to be required
to maintain the margin deposits on the Futures Contract.

As an example of an offsetting transaction, the contractual obligations  arising
from  the sale of one Futures Contract of September Deutschemarks on an exchange
may be  fulfilled at  any time  before delivery  under the  Futures Contract  is
required  (I.E., on a specified date in  September, the "delivery month") by the
purchase of  another Futures  Contract of  September Deutschemarks  on the  same
exchange.  In  such instance,  the  difference between  the  price at  which the
Futures Contract was sold and the price paid for the offsetting purchase,  after
allowance for transaction costs, represents the profit or loss to the Government
Income  Fund,  the  Strategic Income  Fund,  the  Growth &  Income  Fund  or the
Portfolio.
    
 
   
The Government Income Fund's, the Strategic  Income Fund's, the Growth &  Income
Fund's and the Portfolio's Futures transactions will be entered into for hedging
purposes  only; that  is, Futures  Contracts will be  sold to  protect against a
decline in the price of securities or currencies that the Fund or the  Portfolio
owns,  or  Futures  Contracts will  be  purchased  to protect  the  Fund  or the
Portfolio against an increase  in the price of  securities or currencies it  has
committed to purchase or expects to purchase.
    
 
   
"Margin"  with respect to Futures Contracts is  the amount of funds that must be
deposited by the Government Income Fund, the Strategic Income Fund, the Growth &
Income Fund  or  the Portfolio  in  order to  initiate  Futures trading  and  to
maintain  the Fund's or  the Portfolio's open positions  in Futures Contracts. A
margin deposit made when the Futures Contract is entered into ("initial margin")
is intended to assure a Fund's or the Portfolio's performance under the  Futures
Contract.  The margin required for  a particular Futures Contract  is set by the
exchange  on  which  the  Futures  Contract  is  traded,  and  may  be  modified
significantly  from time to time by the  exchange during the term of the Futures
Contract.
    
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission  merchant through  which the Fund  or the Portfolio  entered into the
Futures Contract will be made  on a daily basis as  the price of the  underlying
security,  currency or index fluctuates making the Futures Contract more or less
valuable, a process known as marking-to-market.
 
    RISKS OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts  are
volatile  and  are influenced,  among other  things,  by actual  and anticipated
changes in interest and currency rates, which in turn are affected by fiscal and
monetary policies and national and international political and economic events.
 
There is a risk  of imperfect correlation between  changes in prices of  Futures
Contracts  and  prices  of the  securities  or  currencies in  a  Fund's  or the
Portfolio's portfolio being  hedged. The degree  of imperfection of  correlation
depends  upon circumstances such as: variations in speculative market demand for
Futures and  for securities  or currencies,  including technical  influences  in
Futures  trading; and differences between the financial instruments being hedged
and the  instruments underlying  the standard  Futures Contracts  available  for
trading.  A  decision of  whether, when,  and  how to  hedge involves  skill and
judgment, and even  a well-conceived hedge  may be unsuccessful  to some  degree
because of unexpected market behavior or interest or currency rate trends.
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and option on Futures Contract prices during a single trading day.  The
daily  limit establishes the maximum amount that the price of a Futures Contract
or option may vary either up or down from the previous day's settlement price at
the end  of a  trading session.  Once  the daily  limit has  been reached  in  a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a  particular trading day and therefore does not limit potential losses, because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and option  prices  occasionally have  moved  to  the daily  limit  for  several
consecutive  trading days with  little or no  trading, thereby preventing prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If a Fund  or the  Portfolio were  unable to liquidate  a Futures  or option  on
Futures  position  due  to the  absence  of  a liquid  secondary  market  or the
imposition of price limits, it could  incur substantial losses. The Fund or  the
Portfolio  would  continue to  be subject  to  market risk  with respect  to the
position.  In  addition,  except   in  the  case   of  purchased  options,   the

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
Fund  or the  Portfolio would  continue to be  required to  make daily variation
margin payments and might be required  to maintain the position being hedged  by
the Future or option or to maintain cash or securities in a segregated account.
 
Certain  characteristics  of the  Futures market  might  increase the  risk that
movements in the  prices of Futures  Contracts or options  on Futures might  not
correlate  perfectly  with  movements in  the  prices of  the  investments being
hedged. For example,  all participants  in the  Futures and  options on  Futures
markets  are subject to daily  variation margin calls and  might be compelled to
liquidate Futures  or  options on  Futures  positions whose  prices  are  moving
unfavorably  to avoid being  subject to further  calls. These liquidations could
increase price  volatility  of the  instruments  and distort  the  normal  price
relationship  between the Futures  or options and  the investments being hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous than  margin requirements  in  the securities  markets, there  might  be
increased   participation   by  speculators   in   the  Futures   markets.  This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage,  "program trading"  and other  investment strategies  might result in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options on Futures Contracts are similar to options on securities or  currencies
except that options on Futures Contracts give the purchaser the right, in return
for  the  premium paid,  to  assume a  position in  a  Futures Contract  (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price  at any time  during the period  of the option.  Upon
exercise  of the option, the  delivery of the Futures  position by the writer of
the option to the holder  of the option will be  accompanied by delivery of  the
accumulated balance in the writer's Futures margin account, which represents the
amount  by which the market price of  the Futures Contract, at exercise, exceeds
(in the case of  a call) or  is less than (in  the case of  a put) the  exercise
price  of the option on  the Futures Contract. If an  option is exercised on the
last trading day prior to the expiration date of the option, the settlement will
be made entirely in cash equal to  the difference between the exercise price  of
the  option and the  closing level of  the securities, currencies  or index upon
which the  Futures Contract  is  based on  the  expiration date.  Purchasers  of
options  who fail to exercise their options  prior to the exercise date suffer a
loss of the premium paid.
 
The purchase of  call options  on Futures  can serve as  a long  hedge, and  the
purchase  of put  options on Futures  can serve  as a short  hedge. Writing call
options on Futures can serve as a  limited short hedge, and writing put  options
on  Futures can serve as a limited long  hedge, using a strategy similar to that
used for writing options on securities, foreign currencies or indices.
 
If a Fund or the  Portfolio writes an option on  a Futures Contract, it will  be
required  to  deposit  initial  and variation  margin  pursuant  to requirements
similar to those  applicable to  Futures Contracts. Premiums  received from  the
writing  of an option on  a Futures Contract are  included in the initial margin
deposit.
 
A Fund or the Portfolio may seek to  close out an option position by selling  an
option covering the same Futures Contract and having the same exercise price and
expiration  date.  The ability  to  establish and  close  out positions  on such
options is subject to the maintenance of a liquid secondary market.
 
LIMITATIONS ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS  ON
CURRENCIES
   
To  the  extent that  a Fund  or  the Portfolio  enters into  Futures Contracts,
options on  Futures Contracts  and options  on foreign  currencies traded  on  a
CFTC-regulated  exchange, in each case other than for BONA FIDE hedging purposes
(as defined by the CFTC), the aggregate initial margin and premiums required  to
establish   those  positions  (excluding   the  amount  by   which  options  are
"in-the-money") will not exceed 5% of the  liquidation value of a Fund's or  the
Portfolio's   portfolio,  after  taking  into  account  unrealized  profits  and
unrealized losses on any contracts the  Fund or the Portfolio has entered  into.
In  general, a call option on a  Futures Contract is "in-the-money" if the value
of the underlying Futures Contract exceeds the strike, I.E., exercise, price  of
the  call; a put option on a Futures  Contract is "in-the-money" if the value of
the underlying Futures Contract is exceeded by the strike price of the put. This
guideline may be modified by the  Trust's or the Portfolio's Board of  Trustees,
as  applicable, without a  shareholder vote. This limitation  does not limit the
percentage of a Fund's or the Portfolio's assets at risk to 5%.
    
 
FORWARD CONTRACTS
   
A Forward Contract is an obligation,  generally arranged with a commercial  bank
or  other  currency  dealer, to  purchase  or  sell a  currency  against another
currency at  a  future  date and  price  as  agreed upon  by  the  parties.  The
Government  Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the   Portfolio    either    may    accept   or    make    delivery    of    the

                        AIM GLOBAL GROWTH & INCOME FUND
currency  at the maturity of  the Forward Contract. A  Fund or the Portfolio may
also, if  its contra  party agrees,  prior  to maturity,  enter into  a  closing
transaction involving the purchase or sale of an offsetting contract.
 
A Fund or the Portfolio engages in forward currency transactions in anticipation
of,  or to protect itself against, fluctuations in exchange rates. A Fund or the
Portfolio might sell a particular foreign currency forward, for example, when it
holds bonds denominated in a foreign  currency but anticipates, and seeks to  be
protected against, a decline in the currency against the U.S. dollar. Similarly,
a  Fund or the Portfolio might sell the  U.S. dollar forward when it holds bonds
denominated in U.S. dollars but anticipates, and seeks to be protected  against,
a decline in the U.S. dollar relative to other currencies. Further, the Funds or
the  Portfolio  might purchase  a currency  forward  to "lock  in" the  price of
securities denominated in that currency that it anticipates purchasing.
 
   
Forward Contracts are traded in the interbank market conducted directly  between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any stage for trades. The Government Income Fund, the Strategic Income Fund, the
Growth  & Income Fund  or the Portfolio  will enter into  such Forward Contracts
with major  U.S.  or  foreign  banks  and  securities  or  currency  dealers  in
accordance  with guidelines approved by the  Trust's or the Portfolio's Board of
Trustees, as applicable.
    
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
or  the  Portfolio  may enter  into  Forward  Contracts either  with  respect to
specific transactions or with respect to  the overall investment of the Fund  or
the  Portfolio. The  precise matching  of the  Forward Contract  amounts and the
value of specific securities generally will  not be possible because the  future
value  of such securities in foreign currencies  will change as a consequence of
market movements in the value of  those securities between the date the  Forward
Contract  is  entered into  and  the date  it  matures. Accordingly,  it  may be
necessary for the Fund or the Portfolio to purchase additional foreign  currency
on  the spot (I.E., cash) market (and bear  the expense of such purchase) if the
market value of the  security is less  than the amount  of foreign currency  the
Fund  or the Portfolio is obligated to deliver and if a decision is made to sell
the security and make  delivery of the foreign  currency. Conversely, it may  be
necessary  to sell on the  spot market some of the  foreign currency the Fund or
the Portfolio is  obligated to  deliver. The projection  of short-term  currency
market  movements  is extremely  difficult, and  the  successful execution  of a
short-term hedging strategy is highly  uncertain. Forward Contracts involve  the
risk  that  anticipated currency  movements  will not  be  predicted accurately,
causing the  Fund or  the Portfolio  to sustain  losses on  these contracts  and
transaction costs.
    
 
At  or  before the  maturity of  a Forward  Contract requiring  the Fund  or the
Portfolio to  sell a  currency, the  Fund or  the Portfolio  either may  sell  a
portfolio security and use the sale proceeds to make delivery of the currency or
retain  the  security  and  offset its  contractual  obligation  to  deliver the
currency by  purchasing a  second contract  pursuant to  which the  Fund or  the
Portfolio  will  obtain, on  the  same maturity  date,  the same  amount  of the
currency that it is obligated to  deliver. Similarly, the Fund or the  Portfolio
may  close out a Forward Contract requiring  it to purchase a specified currency
by entering into a second contract, if its contra party agrees, entitling it  to
sell  the same  amount of the  same currency on  the maturity date  of the first
contract. The Fund or the Portfolio would realize a gain or loss as a result  of
entering  into such an offsetting Forward  Contract under either circumstance to
the extent the  exchange rate  or rates  between the  currencies involved  moved
between the execution dates of the first contract and the offsetting contract.
 
The cost to a Fund or the Portfolio of engaging in Forward Contracts varies with
factors  such as the currencies involved, the  length of the contract period and
the market conditions  then prevailing.  Because Forward  Contracts usually  are
entered  into on a principal basis, no fees or commissions are involved. The use
of Forward  Contracts does  not  eliminate fluctuations  in  the prices  of  the
underlying  securities the Fund or the Portfolio owns or intends to acquire, but
it does establish  a rate  of exchange in  advance. In  addition, while  Forward
Contracts  limit the risk  of loss due to  a decline in the  value of the hedged
currencies, they also  limit any  potential gain  that might  result should  the
value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
A  Fund  or the  Portfolio may  use  options on  foreign currencies,  Futures on
foreign currencies,  options  on  Futures  on  foreign  currencies  and  Forward
Contracts  to hedge against movements in the values of the foreign currencies in
which the Fund's or  the Portfolio's securities  are denominated. Such  currency
hedges  can protect  against price movements  in a  security that a  Fund or the
Portfolio owns or  intends to acquire  that are attributable  to changes in  the
value  of the currency in which it  is denominated. Such hedges do not, however,
protect against price movements in the securities that are attributable to other
causes.

                        AIM GLOBAL GROWTH & INCOME FUND
 
A Fund or the Portfolio  might seek to hedge against  changes in the value of  a
particular  currency  when  no  Futures  Contract,  Forward  Contract  or option
involving that currency is available or one of such contracts is more  expensive
than certain other contracts. In such cases, the Fund or the Portfolio may hedge
against  price movements in that currency by entering into a contract on another
currency or basket of currencies, the  values of which the Sub-adviser  believes
will  have a positive correlation to the value of the currency being hedged. The
risk that movements in  the price of the  contract will not correlate  perfectly
with  movements in the price of the currency being hedged is magnified when this
strategy is used.
 
The value of Futures Contracts, options on Futures Contracts, Forward  Contracts
and  options  on  foreign currencies  depends  on  the value  of  the underlying
currency relative  to the  U.S. dollar.  Because foreign  currency  transactions
occurring  in the  interbank market  might involve  substantially larger amounts
than those  involved in  the  use of  Futures  Contracts, Forward  Contracts  or
options,  a Fund or the  Portfolio could be disadvantaged  by dealing in the odd
lot market (generally consisting  of transactions of less  than $1 million)  for
the  underlying foreign  currencies at prices  that are less  favorable than for
round lots.
 
There is no systematic reporting of last sale information for foreign currencies
or any  regulatory requirements  that quotations  available through  dealers  or
other market sources be firm or revised on a timely basis. Quotation information
generally  is representative of very large  transactions in the interbank market
and thus  might not  reflect  odd-lot transactions  where  rates might  be  less
favorable.   The   interbank  market   in  foreign   currencies  is   a  global,
round-the-clock market. To the  extent the U.S. options  or Futures markets  are
closed  while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that  cannot
be  reflected in  the markets  for the Futures  contracts or  options until they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies might  be required  to  take place  within  the country  issuing  the
underlying  currency. Thus, a Fund or the  Portfolio might be required to accept
or make delivery of the underlying foreign currency in accordance with any  U.S.
or foreign regulations regarding the maintenance of foreign banking arrangements
by  U.S. residents  and might  be required  to pay  any fees,  taxes and charges
associated with such delivery assessed in the issuing country.
 
COVER
Transactions using Forward Contracts, Futures Contracts and options (other  than
options  purchased by a Fund or the  Portfolio) expose the Fund or the Portfolio
to an obligation to another party. A  Fund or the Portfolio will not enter  into
any  such  transactions  unless it  owns  either (1)  an  offsetting ("covered")
position in  securities,  currencies, or  other  options, Forward  Contracts  or
Futures  Contracts, or (2) cash, receivables and short-term debt securities with
a value sufficient at all times  to cover its potential obligations not  covered
as  provided in  (1) above.  Each Fund  and the  Portfolio will  comply with SEC
guidelines regarding  cover for  these  instruments and,  if the  guidelines  so
require, set aside cash or liquid securities.
 
Assets  used as cover or  held in a segregated account  cannot be sold while the
position in the corresponding  Forward Contract, Futures  Contract or option  is
open, unless they are replaced with other appropriate assets. If a large portion
of a Fund's or the Portfolio's assets are used for cover or segregated accounts,
it could affect portfolio management or the Fund's or the Portfolio's ability to
meet redemption requests or other current obligations.
 
INTEREST RATE AND CURRENCY SWAPS
   
The  Strategic Income  Fund and the  Portfolio usually will  enter into interest
rate swaps on a net basis, that is, the two payment streams are netted out in  a
cash  settlement on the payment date or  dates specified in the instrument, with
the Strategic Income Fund or the Portfolio receiving or paying, as the case  may
be,  only the net amount of  the two payments. The net  amount of the excess, if
any, of each of the Strategic Income Fund's and the Portfolio's obligations over
its entitlements with respect to each swap will be accrued on a daily basis  and
an  amount of cash or  liquid securities having an  aggregate net asset value at
least equal  to  the accrued  excess  will be  maintained  in an  account  by  a
custodian  that satisfies the requirements of the 1940 Act. The Strategic Income
Fund and the Portfolio will also establish and maintain such segregated accounts
with respect to its total obligations under any swaps that are not entered  into
on  a net basis and with respect to any  caps or floors that are written by that
Fund or  the Portfolio.  The  Sub-adviser, the  Strategic  Income Fund  and  the
Portfolio  believe  that  swaps,  caps  and  floors  do  not  constitute  senior
securities under the  1940 Act and,  accordingly, will not  treat them as  being
subject  to the Fund's and the Portfolio's borrowing restrictions. The Strategic
Income Fund and the Portfolio will not  enter into any swap, cap, floor,  collar
or  other  derivative  transaction unless,  at  the  time of  entering  into the
transaction, the unsecured  long-term debt rating  of the counterparty  combined
with  any credit enhancements is rated  at least A by Moody's  or S&P, or has an
equivalent rating from a nationally recognized statistical

rating organization or is determined to  be of equivalent credit quality by  the
Sub-adviser.  If  a  counterparty defaults,  the  Strategic Income  Fund  or the
Portfolio may have contractual  remedies pursuant to  the agreements related  to
the  transactions. The swap market has grown substantially in recent years, with
a large number of banks and  investment banking firms acting both as  principals
and  as agents utilizing standardized swap  documentation. As a result, the swap
market has become relatively  liquid. Caps, floors and  collars are more  recent
innovations  for  which  standardized  documentation  has  not  yet  been  fully
developed and, for that reason, they are less liquid than swaps.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income  Fund
and  the  Portfolio  each  may  invest  up to  15%  of  net  assets  in illiquid
securities. Securities may  be considered illiquid  if a Fund  or the  Portfolio
cannot  reasonably expect within seven days  to receive approximately the amount
at which the Fund or the Portfolio values such securities. The sale of  illiquid
securities,  if they can  be sold at  all, generally will  require more time and
result in  higher  brokerage  charges  or dealer  discounts  and  other  selling
expenses  than will the  sale of liquid securities,  such as securities eligible
for trading on  U.S. securities  exchanges or in  the over-the-counter  markets.
Moreover,  restricted securities,  which may  be illiquid  for purposes  of this
limitation often sell, if at all, at a price lower than similar securities  that
are not subject to restrictions on resale.
    
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, each Fund  and the Portfolio may  be obligated to pay
all or part of  the registration expenses and  a considerable period may  elapse
between  the time of the decision  to sell and the time  a Fund or the Portfolio
may be permitted to sell a  security under an effective registration  statement.
If,  during such a period, adverse market  conditions were to develop, a Fund or
the Portfolio might obtain a less favorable price than prevailed when it decided
to sell.
 
Not  all  restricted  securities   are  illiquid.  In   recent  years  a   large
institutional   market  has  developed  for  certain  securities  that  are  not
registered under the Securities Act of 1933, as amended ("1933 Act"),  including
private  placements, repurchase agreements, commercial paper, foreign securities
and corporate bonds and notes. These instruments are often restricted securities
because the  securities are  sold in  transactions not  requiring  registration.
Institutional investors generally will not seek to sell these instruments to the
general   public,  but  instead  will  often   depend  either  on  an  efficient
institutional market in which such unregistered securities can be readily resold
or on an issuer's ability to honor  a demand for repayment. Therefore, the  fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule  144A under the 1933 Act establishes  a "safe harbor" from the registration
requirements of the  1933 Act  for resales  of certain  securities to  qualified
institutional  buyers.  Institutional  markets  for  restricted  securities have
developed as a result of Rule 144A, providing both readily ascertainable  values
for  restricted securities and the ability to liquidate an investment to satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance and  settlement of  unregistered securities  of domestic  and  foreign
issuers,  such as  the PORTAL  System sponsored  by the  National Association of
Securities Dealers,  Inc.  An  insufficient number  of  qualified  institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a  Fund or the  Portfolio, however, could affect  adversely the marketability of
such portfolio securities and a Fund or the Portfolio might be unable to dispose
of such securities promptly or at favorable prices.
 
   
With  respect  to  liquidity  determinations  generally,  the  Trust's  or   the
Portfolio's  Board of Trustees  has the ultimate  responsibility for determining
whether specific securities, including restricted securities eligible for resale
to qualified institutional buyers pursuant to Rule 144A under the 1933 Act,  are
liquid or illiquid. The Board has delegated the

function  of making day-to-day determinations of liquidity to the Sub-adviser in
accordance with procedures  approved by  the Board. The  Sub-adviser takes  into
account  a number of factors in reaching liquidity decisions, including: (i) the
frequency of  trading in  the security;  (ii) the  number of  dealers that  make
quotes  for the security;  (iii) the number  of dealers that  have undertaken to
make a market in  the security; (iv) the  number of other potential  purchasers;
and  (v) the nature of the security and  how trading is effected (e.g., the time
needed to  sell the  security, how  offers are  solicited and  the mechanics  of
transfer). The Sub-adviser will monitor the liquidity of securities held by each
Fund  and the Portfolio and report periodically on such decisions to the Trust's
or the Portfolio's  Board of  Trustees. Moreover,  as noted  in the  Prospectus,
certain  securities, such as those subject  to registration restrictions of more
than seven  days,  will generally  be  treated  as illiquid.  If  the  liquidity
percentage  restriction of a Fund  or the Portfolio is  satisfied at the time of
investment, a later increase in the percentage of illiquid securities held by  a
Fund or the Portfolio resulting from a change in market value or assets will not
constitute a violation of that restriction. If as a result of a change in market
value  or assets,  the percentage  of illiquid  securities held  by the  Fund or
Portfolio increases  above  the  applicable limit,  the  Sub-adviser  will  take
appropriate  steps to bring the aggregate  amount of illiquid assets back within
the prescribed  limitations  as  soon as  reasonably  practicable,  taking  into
account the effect of any disposition on the Fund or the Portfolio.
    
 
FOREIGN SECURITIES
    POLITICAL,  SOCIAL AND ECONOMIC  RISKS. Investing in  securities of non-U.S.
companies may entail additional risks due to the potential political, social and
economic instability  of  certain  countries and  the  risks  of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment, convertibility of currencies into  U.S. dollars and on  repatriation
of  capital invested.  In the  event of  such expropriation,  nationalization or
other confiscation by any country, either a Fund or the Portfolio could lose its
entire investment in any such country.
 
    RELIGIOUS, POLITICAL AND  ETHNIC INSTABILITY. Certain  countries in which  a
Fund or the Portfolio may invest may have groups that advocate radical religious
or revolutionary philosophies or support ethnic independence. Any disturbance on
the   part  of  such  individuals  could  carry  the  potential  for  widespread
destruction or  confiscation  of  property owned  by  individuals  and  entities
foreign  to such country and could cause the loss of a Fund's or the Portfolio's
investment in those  countries. Instability  may also result  from, among  other
things:  (i) authoritarian governments or  military involvement in political and
economic   decision-making,    including   changes    in   government    through
extra-constitutional  means;  (ii) popular  unrest  associated with  demands for
improved political, economic and social conditions; and (iii) hostile  relations
with  neighboring  or  other  countries.  Such  political,  social  and economic
instability could disrupt the principal financial markets in which a Fund or the
Portfolio  invests  and  adversely  affect  the  value  of  the  Fund's  or  the
Portfolio's assets.
 
   
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial restrictions on investments  in their capital markets,  particularly
their  equity markets, by  foreign entities such as  the Government Income Fund,
the Strategic Income  Fund, the  Growth & Income  Fund or  the Portfolio.  These
restrictions  or controls may  at times limit or  preclude investment in certain
securities and may increase the  cost and expenses of  a Fund or the  Portfolio.
For  example,  certain  countries  require  prior  governmental  approval before
investments by  foreign  persons  may  be  made, or  may  limit  the  amount  of
investment  by foreign persons in a  particular company, or limit the investment
by foreign persons to only a specific class of securities of a company that  may
have  less  advantageous  terms than  securities  of the  company  available for
purchase by nationals. Moreover, the national policies of certain countries  may
restrict  investment opportunities in issuers  or industries deemed sensitive to
national interests. In  addition, some countries  require governmental  approval
for the repatriation of investment income, capital or the proceeds of securities
sales  by  foreign investors.  In addition,  if  there is  a deterioration  in a
country's balance  of  payments or  for  other  reasons, a  country  may  impose
restrictions  on foreign capital remittances abroad. The Government Income Fund,
the Strategic Income Fund, the  Growth & Income Fund  or the Portfolio could  be
adversely   affected  by  delays  in,  or  a  refusal  to  grant,  any  required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
    
 
   
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting  principles. Most  of  the foreign  securities held  by  the
Government  Income Fund, the Strategic Income Fund,  the Growth & Income Fund or
the Portfolio will not be registered with  the SEC or regulators of any  foreign
country,  nor  will  the  issuers  thereof be  subject  to  the  SEC's reporting

requirements. Thus, there  will be  less available  information concerning  most
foreign  issuers of securities held by the Government Income Fund, the Strategic
Income Fund,  the Growth  & Income  Fund  and the  Portfolio than  is  available
concerning  U.S.  issuers. In  instances where  the  financial statements  of an
issuer are  not deemed  to reflect  accurately the  financial situation  of  the
issuer,  the Sub-adviser  will take appropriate  steps to  evaluate the proposed
investment, which may include on-site inspection of the issuer, interviews  with
its   management  and   consultations  with   accountants,  bankers   and  other
specialists. There is  substantially less publicly  available information  about
foreign  companies  than  there are  reports  and ratings  published  about U.S.
companies and  the U.S.  Government. In  addition, where  public information  is
available, it may be less reliable than such information regarding U.S. issuers.
Issuers  of securities in foreign jurisdictions are generally not subject to the
same degree of regulation as  are U.S. issuers with  respect to such matters  as
restrictions  on market  manipulation, insider trading  rules, shareholder proxy
requirements and timely disclosure of information.
    
 
    CURRENCY FLUCTUATIONS. Because  the Funds  and the  Portfolio, under  normal
circumstances,  will invest  substantial portions of  their total  assets in the
securities of foreign issuers which  are denominated in foreign currencies,  the
strength  or weakness  of the U.S.  dollar against such  foreign currencies will
account for part of  each Fund's and the  Portfolio's investment performance.  A
decline  in the value  of any particular  currency against the  U.S. dollar will
cause a decline  in the U.S.  dollar value  of each Fund's  and the  Portfolio's
holdings  of securities  and cash denominated  in such  currency and, therefore,
will cause an overall decline in their  respective net asset values and any  net
investment  income  and  capital  gains  derived  from  such  securities  to  be
distributed in U.S. dollars to shareholders of the Funds. Moreover, if the value
of the foreign currencies in which a  Fund or the Portfolio receives its  income
declines  relative to the U.S. dollar between  the receipt of the income and the
making of  Fund distributions,  the Fund  or the  Portfolio may  be required  to
liquidate securities in order to make distributions if the Fund or the Portfolio
has insufficient cash in U.S. dollars to meet distribution requirements.
 
The  rate of exchange between the U.S. dollar and other currencies is determined
by several factors including  the supply and  demand for particular  currencies,
central  bank efforts to support particular currencies, the relative movement of
interest rates and the pace of business activity in the other countries, and the
United States, and other economic  and financial conditions affecting the  world
economy.
 
Although  the Funds and the Portfolio value  their assets daily in terms of U.S.
dollars, they do not intend to convert holdings of foreign currencies into  U.S.
dollars  on a daily basis. The  Funds and the Portfolio will  do so from time to
time, and  investors  should be  aware  of  the costs  of  currency  conversion.
Although  foreign exchange dealers do  not charge a fee  for conversion, they do
realize a profit based on the difference ("spread") between the prices at  which
they are buying and selling various currencies. Thus, a dealer may offer to sell
a  foreign currency  to a  Fund at  one rate,  while offering  a lesser  rate of
exchange should the Fund desire to sell that currency to the dealer.
 
    ADVERSE MARKET CHARACTERISTICS.  Securities of many  foreign issuers may  be
less  liquid and their  prices more volatile than  securities of comparable U.S.
issuers. In  addition,  foreign securities  markets  and brokers  generally  are
subject  to less governmental  supervision and regulation than  in the U.S., and
foreign securities transactions usually are subject to fixed commissions,  which
generally  are  higher  than  negotiated commissions  on  U.S.  transactions. In
addition,  foreign  securities  transactions  may  be  subject  to  difficulties
associated  with the settlement of such transactions. Delays in settlement could
result in  temporary  periods  when  assets  of a  Fund  or  the  Portfolio  are
uninvested  and no  return is  earned thereon.  The inability  of a  Fund or the
Portfolio to make intended security  purchases due to settlement problems  could
cause  it to miss attractive opportunities.  Inability to dispose of a portfolio
security due to settlement problems either could  result in losses to a Fund  or
the  Portfolio due to subsequent declines in value of the portfolio security or,
if the Fund or the Portfolio has  entered into a contract to sell the  security,
could  result  in  possible liability  to  the purchaser.  The  Sub-adviser will
consider such difficulties when determining the allocation of each Fund's or the
Portfolio's  assets,  although  the  Sub-adviser  does  not  believe  that  such
difficulties  will  have  a  material  adverse  effect  on  the  Funds'  or  the
Portfolio's portfolio trading activities.
 
The Funds and the Portfolio may use foreign custodians, which may involve  risks
in  addition to those related to the  use of U.S. custodians. Such risks include
uncertainties  relating  to:  (i)  determining  and  monitoring  the   financial
strength,  reputation and  standing of  the foreign  custodian; (ii) maintaining
appropriate safeguards to protect the Funds' and the Portfolio's investments and
(iii) possible difficulties  in obtaining and  enforcing judgments against  such
custodians.

                        AIM GLOBAL GROWTH & INCOME FUND
 
    WITHHOLDING  TAXES. Each  Fund's and  the Portfolio's  net investment income
from foreign issuers may be subject to withholding taxes by the foreign issuer's
country, thereby reducing the Fund's and the Portfolio's income or delaying  the
receipt of income where those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION.  To the  extent a Fund  invests a significant  portion of its
assets in securities of issuers located in a particular country or region of the
world, such Portfolio may be subject to greater risks and may experience greater
volatility than a fund that is more broadly diversified geographically.
 
    SPECIAL CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The  countries
that  are members of the European Economic Community ("Common Market") (Belgium,
Denmark, France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg,  Netherlands,
Portugal,  Spain, and the United Kingdom)  eliminated certain import tariffs and
quotas and  other trade  barriers with  respect  to one  another over  the  past
several  years. The Sub-adviser  believes that this  deregulation should improve
the prospects  for economic  growth in  many Western  European countries.  Among
other  things, the deregulation could enable  companies domiciled in one country
to avail  themselves  of lower  labor  costs  existing in  other  countries.  In
addition,  this deregulation could benefit companies domiciled in one country by
opening additional  markets for  their goods  and services  in other  countries.
Since,  however, it is not  clear what the exact form  or effect of these Common
Market reforms  will be  on business  in  Western Europe,  it is  impossible  to
predict  the long-term  impact of  the implementation  of these  programs on the
securities owned by a Fund.
 
    SPECIAL CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN  COUNTRIES.
Investing  in Russia  and Eastern European  countries involves a  high degree of
risk and special considerations not  typically associated with investing in  the
United  States securities markets, and  should be considered highly speculative.
Such risks include: (1)  delays in settling portfolio  transactions and risk  of
loss  arising out of the system of  share registration and custody; (2) the risk
that it may be impossible  or more difficult than  in other countries to  obtain
and/or  enforce a  judgement; (3) pervasiveness  of corruption and  crime in the
economic system; (4) currency exchange rate volatility and the lack of available
currency hedging instruments; (5) higher rates of inflation (including the  risk
of   social  unrest  associated  with   periods  of  hyper-inflation)  and  high
unemployment; (6) controls on foreign investment and local practices disfavoring
foreign investors and limitations on  repatriation of invested capital,  profits
and  dividends, and on  a fund's ability  to exchange local  currencies for U.S.
dollars; (7) political instability and social unrest and violence; (8) the  risk
that  the governments of Russia and Eastern European countries may decide not to
continue to support the economic reform programs implemented recently and  could
follow  radically different political and/or  economic policies to the detriment
of investors,  including non-market-oriented  policies such  as the  support  of
certain  industries at the expense of other sectors or investors, or a return to
the centrally planned economy that existed  when such countries had a  communist
form of government; (9) the financial condition of companies in these countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of  international trade; (11)  the risk that  the tax system  in these countries
will not  be reformed  to prevent  inconsistent, retroactive  and/or  exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly  since 1990. The general government position has deteriorated as a
result of weakening economic  growth and stimulative  measures taken to  support
economic  activity and to  restore financial stability.  Although the decline in
interest  rates  and  fiscal  stimulation   packages  have  helped  to   contain
recessionary  forces, uncertainties remain. Japan is also heavily dependent upon
international trade, so its  economy is especially  sensitive to trade  barriers
and  disputes.  Japan has  had difficult  relations  with its  trading partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible that  trade sanctions  and other  protectionist measures  could  impact
Japan adversely in both the short and the long term.
 
The  common  stocks  of many  Japanese  companies trade  at  high price-earnings
ratios. Differences  in accounting  methods  make it  difficult to  compare  the
earnings  of  Japanese companies  with those  of  companies in  other countries,
especially in the  U.S. In  general, however, reported  net income  in Japan  is
understated  relative to  U.S. accounting standards  and this is  one reason why
price-earnings  ratios  of  the  stocks   of  Japanese  companies  have   tended
historically  to be  higher than  those for  U.S. stocks.  In addition, Japanese
companies have  tended to  have  higher growth  rates  than U.S.  companies  and
Japanese  interest rates  have generally  been lower than  in the  U.S., both of
which factors tend to result in  lower discount rates and higher  price-earnings
ratios in Japan than in the U.S.
 
The  Japanese securities  markets are  less regulated  than those  in the United
States. Evidence has emerged from time to time of distortion of market prices to
serve political or other purposes.  Shareholders' rights are not always  equally

                        AIM GLOBAL GROWTH & INCOME FUND
enforced.  In addition, Japan's banking  industry is undergoing problems related
to bad loans and declining values in real estate.
 
    SPECIAL CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of  the
risks  associated with international investments  are heightened for investments
in Pacific region  countries. For  example, some  of the  currencies of  Pacific
region  countries  have experienced  steady  devaluations relative  to  the U.S.
dollar, and major  adjustments have been  made periodically in  certain of  such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional  disputes  also exist  between South  Korea  and North  Korea. In
addition, the  Funds  may  invest  in  Hong  Kong,  which  reverted  to  Chinese
Administration  on July  1, 1997.  Investments in  Hong Kong  may be  subject to
expropriation, national, nationalization or confiscation,  in which case a  Fund
could  lose its entire  investment in Hong  Kong. In addition,  the reversion of
Hong Kong also presents a risk that the Hong Kong dollar will be devalued and  a
risk  of possible  loss of  investor confidence  in Hong  Kong's currency, stock
market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American  countries have experienced substantial,  and in some periods extremely
high, rates of  inflation for many  years. Inflation and  rapid fluctuations  in
inflation  rates have had and may continue  to have very negative effects on the
economies and securities  markets of certain  Latin American countries.  Certain
Latin  American countries are also among the largest debtors to commercial banks
and foreign governments. At times certain Latin American countries have declared
moratoria on  the payment  of principal  and/or interest  on external  debt.  In
addition,  certain  Latin  American  securities  markets  have  experienced high
volatility in recent years.
 
Latin American countries may  also close certain sectors  of their economies  to
equity  investments  by foreigners.  Further due  to  the absence  of securities
markets and  publicly  owned corporations  and  due to  restrictions  on  direct
investment  by foreign entities,  investments may only be  made in certain Latin
American  countries  solely   or  primarily   through  governmentally   approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at  artificial levels to the U.S. dollar rather than at levels determined by the
market. This type  of system can  lead to  sudden and large  adjustments in  the
currency  which, in turn, can  have a disruptive and  negative effect on foreign
investors. For example, in late  1994, the value of  the Mexican peso lost  more
than one-third of its value relative to the U.S. dollar.
 
   
    SPECIAL  CONSIDERATIONS  AFFECTING  EMERGING MARKETS.  The  Strategic Income
Fund, the Growth & Income Fund and  the Portfolio may invest in debt  securities
in  emerging markets. Investing  in securities in  emerging countries may entail
greater  risks  than  investing  in  debt  securities  in  developed  countries.
Similarly,  for  Growth &  Income Fund,  investing in  the equity  securities of
companies in emerging  markets entails additional  risks. These risks  affecting
debt  and  equity  investments  in emerging  markets  include  (i)  less social,
political and economic stability; (ii) the small current size of the markets for
such securities and the  currently low or nonexistent  volume of trading,  which
result  in a lack  of liquidity and  in greater price  volatility; (iii) certain
national policies which may restrict  the Funds' and the Portfolio's  investment
opportunities,  including restrictions  on investment  in issuers  or industries
deemed sensitive  to national  interests;  (iv) foreign  taxation; and  (v)  the
absence  of  developed structures  governing  private or  foreign  investment or
allowing for judicial redress for injury to private property.
    
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in  more developed markets.  In such  emerging securities markets
there may be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economies  and securities
markets of certain emerging market countries.

- --------------------------------------------------------------------------------
 
   
Each Fund and the Portfolio has adopted the following investment limitations  as
fundamental  policies which may not be changed without approval by a majority of
the outstanding shares  of the Fund  or Portfolio, as  applicable. Whenever  the
High  Income Fund is requested to vote on a change in the investment limitations
of the Portfolio, the Fund will hold a meeting of its shareholders and will cast
its votes as instructed by its shareholders.
    
 
                             GOVERNMENT INCOME FUND
 
The Government Income Fund may not:
 
        (1) Purchase any security if, as a result of that purchase, 25% or  more
    of the Fund's total assets would be invested in securities of issuers having
    their  principal business activities in the  same industry, except that this
    limitation does not  apply to securities  issued or guaranteed  by the  U.S.
    government, its agencies or instrumentalities;
 
        (2)  Purchase or sell real estate, except that investments in securities
    of issuers  that invest  in real  estate and  investments in  mortgage-based
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    the Fund may exercise rights  under agreements relating to such  securities,
    including  the right to  enforce security interests and  to hold real estate
    acquired by  reason  of such  enforcement  until  that real  estate  can  be
    liquidated in an orderly manner;
 
        (3)  Engage in the business of underwriting securities of other issuers,
    except to the extent that the Fund might be considered an underwriter  under
    the  federal securities laws in connection with its disposition of portfolio
    securities;
 
        (4) Make loans, except through loans of portfolio securities or  through
    repurchase  agreements, provided that  for purposes of  this limitation, the
    acquisition of bonds, debentures, other  debt securities or instruments,  or
    participations  or  other interests  therein  and investments  in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (5) Issue senior securities or  borrow money, except as permitted  under
    the  1940 Act and then not  in excess of 33 1/3%  of the Fund's total assets
    (including  the  amount  borrowed  but   reduced  by  any  liabilities   not
    constituting  borrowings) at the time of the borrowing, except that the Fund
    may borrow up to  an additional 5%  of its total  assets (not including  the
    amount borrowed) for temporary or emergency purposes; or
 
        (6)  Purchase or sell  physical commodities, but  the Fund may purchase,
    sell or enter into financial options and futures, forward and spot  currency
    contracts,  swap transactions  and other  financial contracts  or derivative
    instruments.
 
Notwithstanding any other investment policy of the Fund, the Fund may invest all
of  its  investable  assets  (cash,   securities  and  receivables  related   to
securities)  in an  open-end management investment  company having substantially
the same investment objective, policies and limitations as the Fund.
 
For purposes  of the  Fund's concentration  policy contained  in limitation  (1)
above,  the Fund intends to comply with  the SEC staff positions that securities
issued or  guaranteed  as  to  principal and  interest  by  any  single  foreign
government or any supranational organizations in the aggregate are considered to
be securities of issuers in the same industry.
 
   
The  following  investment  policies  of  the  Government  Income  Fund  are not
fundamental policies and may be changed by vote of the Trust's Board of Trustees
without shareholder approval. The Fund may not:
    
 
        (1) Borrow  money to  purchase  securities or  borrow money  except  for
    temporary  or emergency purposes.  While borrowings exceed  5% of the Fund's
    total assets, the Fund will not make any additional investments;
 
        (2) Invest in securities of an issuer if the investment would cause  the
    Fund to own more than 10% of any class of securities of any one issuer;

        (3)  Purchase securities  on margin, provided  that the  Fund may obtain
    short-term credits as may  be necessary for the  clearance of purchases  and
    sales  of securities,  and further  provided that  the Fund  may make margin
    deposits in  connection  with its  use  of financial  options  and  futures,
    forward  and spot currency contracts,  swap transactions and other financial
    contracts or derivative instruments;
 
        (4) Enter into a futures contract, if, as a result thereof, more than 5%
    of the Fund's total assets  (taken at market value  at the time of  entering
    into the contract) would be committed to margin on such futures contracts;
 
        (5)  Purchase securities for which there is no readily available market,
    or enter into repurchase  agreements or purchase  time deposits maturing  in
    more  than seven days, or  purchase OTC options or  hold assets set aside to
    cover OTC options written by the Fund, if immediately after and as a result,
    the value of  such securities  would exceed, in  the aggregate,  15% of  the
    Fund's net assets; or
 
        (6)  Mortgage, pledge, or  hypothecate any of  its assets, provided that
    this shall not apply  to the transfer of  securities in connection with  any
    permissible  borrowing  or  to collateral  arrangements  in  connection with
    permissible activities.
 
                             STRATEGIC INCOME FUND
 
The Strategic Income Fund may not:
 
        (1) Purchase any security if, as a result of that purchase, 25% or  more
    of the Fund's total assets would be invested in securities of issuers having
    their  principal business activities in the  same industry, except that this
    limitation does not  apply to securities  issued or guaranteed  by the  U.S.
    government, its agencies or instrumentalities;
 
        (2)  Purchase or sell real estate, except that investments in securities

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject to policies  established by  the Trust's  and the  Portfolio's Board  of
Trustees,  the Sub-adviser  is responsible for  the execution  of the Government
Income Fund's, the Strategic Income Fund's,  the Growth & Income Fund's and  the
Portfolio's  portfolio  transactions and  the  selection of  broker/dealers that
execute such  transactions  on behalf  of  these  Funds and  the  Portfolio.  In
executing  transactions,  the Sub-adviser  seeks the  best  net results  for the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund  and
the  Portfolio, taking  into account  such factors  as the  price (including the
applicable brokerage commission or dealer spread), size of the order, difficulty
of execution  and operational  facilities  of the  firm involved.  Although  the
Sub-adviser generally seeks reasonably competitive commission rates and spreads,
payment  of the lowest  commission or spread is  not necessarily consistent with
the best net  results. While  the Funds  and the  Portfolio may  engage in  soft
dollar arrangements for research services, as described below, neither the Funds
nor  the Portfolio has any obligation to deal with any broker/dealer or group of
broker/dealers in the execution of portfolio transactions.
    
 
Debt securities generally are traded  on a "net" basis  with a dealer acting  as
principal for its own account without a stated commission, although the price of
the  security  usually  includes  a  profit  to  the  dealer.  U.S.  and foreign
government securities and money market  instruments generally are traded in  the
OTC  markets. In underwritten  offerings, securities usually  are purchased at a
fixed price which  includes an  amount of  compensation to  the underwriter.  On
occasion,  securities may be purchased directly from an issuer, in which case no
commissions or discounts  are paid.  Broker/dealers may  receive commissions  on
futures, currency and options transactions.
 
Consistent  with the interests  of the Funds and  the Portfolio, the Sub-adviser
may  select  brokers  to  execute  the  Funds'  and  the  Portfolio's  portfolio
transactions on the basis of the research and brokerage services they provide to
the  Sub-adviser for  its use in  managing the  Funds and the  Portfolio and its
other advisory accounts. Such services may include furnishing analyses,  reports
and  information concerning issuers, industries, securities, geographic regions,
economic factors and  trends, portfolio strategy,  and performance of  accounts;
and  effecting  securities  transactions  and  performing  functions  incidental
thereto (such  as clearance  and settlement).  Research and  brokerage  services
received  from such brokers are in addition to, and not in lieu of, the services
required to  be performed  by the  Sub-adviser under  investment management  and
administration  contracts. A commission paid to  such brokers may be higher than
that which another qualified  broker would have charged  for effecting the  same
transaction,  provided that the  Sub-adviser determines in  good faith that such
commission is reasonable in terms either  of that particular transaction or  the
overall responsibility of the Sub-adviser to the Funds and the Portfolio and its
other clients and that the total commissions paid by the Funds and the Portfolio
will  be reasonable in  relation to the  benefits received by  the Funds and the
Portfolio over  the long  term.  Research services  may  also be  received  from
dealers who execute Fund transactions in OTC markets.
 
The  Sub-adviser may allocate brokerage  transactions to broker/dealers who have
entered into arrangements under which  the broker/dealer allocates a portion  of
the  commissions paid by the Funds or the Portfolio toward payment of the Funds'
or the Portfolio's expenses, such as transfer agent and custodian fees.
 
Investment decisions for each  Fund and the Portfolio  and for other  investment
accounts  managed by  the Sub-adviser  are made  independently of  each other in
light  of   differing  conditions.   However,  the   same  investment   decision
occasionally may be made for two or more of such accounts, including one or both
Funds  and the  Portfolio. In such  cases, simultaneous  transactions may occur.
Purchases or sales are then allocated as  to price or amount in a manner  deemed
fair  and equitable to all accounts involved.  While in some cases this practice
could have a detrimental effect upon the  price or value of the security as  far
as  the Funds and  the Portfolio are  concerned, in other  cases the Sub-adviser
believes that coordination and the ability to participate in volume transactions
will be beneficial to the Funds and the Portfolio.
 
   
Under a policy adopted by the Trust's and the Portfolio's Board of Trustees, and
subject to the  policy of obtaining  the best net  results, the Sub-adviser  may
consider  a broker/dealer's sale of the shares  of the Funds and the other funds
for which  AIM or  the Sub-adviser  serves as  investment manager  in  selecting
brokers and dealers for the execution of portfolio

transactions.  This  policy does  not imply  a  commitment to  execute portfolio
transactions through all broker/dealers that sell  shares of the Funds and  such
other funds.
 
Each  Fund  and  the  Portfolio  contemplates  purchasing  most  foreign  equity
securities in  over-the-counter  markets  or  stock  exchanges  located  in  the
countries  in  which the  respective  principal offices  of  the issuers  of the
various securities are located, if that is the best available market. The  fixed
commissions  paid  in  connection  with  most  such  foreign  stock transactions
generally are higher than negotiated commissions on United States  transactions.
There  generally is less government supervision  and regulation of foreign stock
exchanges and brokers than  in the United  States. Foreign security  settlements
may   in  some  instances  be  subject  to  delays  and  related  administrative
uncertainties.
 
Foreign equity securities may be held by a Fund and the Portfolio in the form of
American Depository  Receipts  ("ADRs"), American  Depository  Shares  ("ADSs"),
Continental   Depository  Receipts  ("CDRs")  or  European  Depository  Receipts
("EDRs") or securities convertible into  foreign equity securities. ADRs,  ADSs,
CDRs  and EDRs may be listed on stock exchanges, or traded in the OTC markets in
the United States or  Europe, as the  case may be.  ADRs, like other  securities
traded in the United States, will be subject to negotiated commission rates. The
foreign  and domestic debt securities and  money market instruments in which the
Funds and the Portfolio may invest generally are traded in the OTC markets.
 
   
The Funds and  the Portfolio  contemplate that,  consistent with  the policy  of
obtaining  the best net results, brokerage transactions may be conducted through
certain companies that are affiliates of AIM and the Sub-adviser. The  Company's
Board of Trustees has adopted procedures in conformity with Rule 17e-1 under the
1940  Act to ensure that  all brokerage commissions paid  to such affiliates are
reasonable and fair in the  context of the market  in which they are  operating.
Any  such transactions  will be effected  and related compensation  paid only in
accordance with applicable SEC regulations.  For the fiscal years ended  October
31,  1997, 1996 and 1995, the  Portfolio paid aggregate brokerage commissions of
$0, $86,600 and $0, respectively. For  the fiscal years ended October 31,  1997,
1996  and 1995, the Government Income  Fund paid aggregate brokerage commissions
of $4,987, $24,663 and $0, respectively. For the fiscal years ended October  31,
1997,  1996  and  1995,  the  Strategic  Income  Fund  paid  aggregate brokerage
commissions of $6,177, $85,404 and $0, respectively. For the fiscal years  ended
October  31,  1997, 1996,  and 1995,  the  Growth &  Income Fund  paid aggregate
brokerage commissions of $463,307, $257,953 and $318,958, respectively. For  the
fiscal  years ended October 31, 1996 and 1997,  the Growth & Income Fund paid to
LGT Bank  in Liechtenstein,  AG,  which was  an "affiliated"  broker,  aggregate
brokerage  commissions of  $16,898 and  $12,262, respectively,  for transactions
involving purchases and  sales of portfolio  securities which represented  6.55%
and 2.65%, respectively, of the total brokerage commissions paid by the Fund and
5.69%  and 2.94%, respectively,  of the aggregate  dollar amount of transactions

Each Fund and the  Portfolio engages in portfolio  trading when the  Sub-adviser
concludes  that the sale of a security owned  by a Fund and the Portfolio and/or
the purchase of another  security of better value  can enhance principal  and/or
increase  income. A  security may  be sold to  avoid any  prospective decline in
market value, or a security may be  purchased in anticipation of a market  rise.
Consistent  with  each  Fund's  and  the  Portfolio's  investment  objectives, a
security also may be sold and a comparable security purchased coincidentally  in
order  to take  advantage of what  is believed to  be a disparity  in the normal
yield and price relationship between the two securities. Although the Funds  and
the  Portfolio  generally do  not intend  to trade  for short-term  profits, the
securities in each Fund's  and the Portfolio's portfolio  will be sold  whenever
the  Sub-adviser believes  it is  appropriate to  do so,  without regard  to the
length of time a particular security  may have been held. Portfolio turnover  is
calculated  by dividing the lesser of sales or purchases of portfolio securities
by each Fund's or the  Portfolio's average month-end portfolio value,  excluding
short-term  investments.  Higher  portfolio  turnover  involves  correspondingly
greater brokerage commissions  and other transaction  costs that a  Fund or  the
Portfolio will bear directly, and could result in the realization of net capital
gains  that would  be taxable  when distributed  to shareholders.  The portfolio
turnover rates for the Government Income  Fund, Strategic Income Fund, Growth  &
Income Fund and the Portfolio the last two fiscal years were as follows:

                             THE DISTRIBUTION PLANS
    
 
   
THE  CLASS A PLAN. The Trust has  adopted a Master Distribution Plan pursuant to
Rule 12b-1 under the 1940 Act relating to  the Class A shares of the Funds  (the
"Class A Plan"). The Class A Plan provides that the Class A shares pay 0.35% per
annum  of their average daily net assets as compensation to AIM Distributors for
the purpose of financing any activity  which is primarily intended to result  in
the  sale of Class  A shares. Of such  amounts, each Fund pays  a service fee of
0.25% of the average daily net assets attributable to Class A shares to selected
dealers and  other institutions  which furnish  continuing personal  shareholder
services  to their  customers who  purchase and  own Class  A shares. Activities
appropriate for financing under  the Class A Plan  include, but are not  limited
to,  the  following:  printing  of  prospectuses  and  statements  of additional
information  and  reports  for  other  than  existing  shareholders;   overhead;
preparation  and  distribution  of advertising  material  and  sales literature;
expenses of organizing and conducting  sales seminars; supplemental payments  to
dealers  and other institutions such as asset-based sales charges or as payments
of  service  fees   under  shareholder  service   arrangements;  and  costs   of
administering the Class A Plan.
    
 
   
THE CLASS B PLAN. The Trust has also adopted a Master Distribution Plan pursuant
to  Rule 12b-1 under the 1940  Act relating to Class B  shares of the Funds (the
"Class B Plan", and collectively with the Class A Plan, the "Plans"). Under  the
Class  B Plan, each Fund pays compensation to AIM Distributors at an annual rate
of 1.00% of the average daily net assets attributable to Class B shares. Of such
amount, each Fund pays a  service fee of 0.25% of  the average daily net  assets
attributable  to Class B shares to selected dealers and other institutions which
furnish continuing personal shareholder services to their customers who purchase
and own Class B shares. Amounts paid in accordance with the Class B Plan may  be
used to finance any activity primarily intended to result in the sale of Class B
shares,  including but not limited to printing of prospectuses and statements of
additional  information  and  reports  for  other  than  existing  shareholders;
overhead;  preparation  and  distribution  of  advertising  material  and  sales
literature; expenses of organizing  and conducting sales seminars;  supplemental
payments  to dealers and other institutions such as asset-based sales charges or
as payments of service fees under shareholder service arrangements; and costs of
administering the  Class B  Plan. AIM  Distributors may  transfer and  sell  its
rights  to payments  under the  Class B  Plan in  order to  finance distribution
expenditures in respect of Class B shares.
    
 
   
BOTH PLANS. Pursuant to  an incentive program, AIM  Distributors may enter  into
agreements  ("Shareholder Service Agreements")  with investment dealers selected
from time  to  time  by  AIM Distributors  for  the  provision  of  distribution
assistance  in connection with  the sale of  the Funds' shares  to such dealers'
customers, and for the provision of continuing personal shareholder services  to
customers  who may from time to time  directly or beneficially own shares of the
Funds. The distribution assistance and continuing personal shareholder  services
to  be rendered by dealers under the Shareholder Service Agreements may include,
but shall  not be  limited  to, the  following: distributing  sales  literature;
answering  routine customer inquiries concerning  the Funds; assisting customers
in changing  dividend  options,  account  designations  and  addresses,  and  in
enrolling  in any of the several  special investment plans offered in connection
with the  purchase of  the Funds'  shares; assisting  in the  establishment  and
maintenance  of customer accounts and records  and in the processing of purchase
and  redemption  transactions;  investing   dividends  and  any  capital   gains
distributions  automatically  in the  Funds'  shares; and  providing  such other
information and services as the Funds or the customer may reasonably request.
    
 
   
Under the Plans, in addition  to the Shareholder Service Agreements  authorizing
payments   to  selected  dealers,  banks  may  enter  into  Shareholder  Service
Agreements authorizing  payments under  the  Plans to  be  made to  banks  which
provide services to their customers who have purchased shares. Services provided
pursuant to Shareholder Service Agreements with banks may include some or all of
the  following: answering shareholder inquiries  regarding the Funds; performing
sub-accounting; establishing and maintaining  shareholder accounts and  records;
processing  customer  purchase and  redemption transactions;  providing periodic
statements showing a shareholder's account  balance and the integration of  such
statements  with those of  other transactions and  balances in the shareholder's
other accounts serviced by the  bank; forwarding applicable prospectuses,  proxy
statements,  reports and notices to bank clients  who hold Fund shares; and such
other administrative services as the Funds reasonably may request, to the extent
permitted by applicable statute, rule  or regulation. Similar agreements may  be
permitted  under the Plans for institutions  which provide recordkeeping for and
administrative services to 401(k) plans.
    
 
   
Financial intermediaries and any other  person entitled to receive  compensation
for selling Fund shares may receive different compensation for selling shares of
one particular class over another.

                       AIM GLOBAL GOVERNMENT INCOME FUND
                           AIM STRATEGIC INCOME FUND

                        AIM GLOBAL GROWTH & INCOME FUND
 
   
Under a Shareholder Service Agreement, each Fund agrees to pay periodically fees
to  selected dealers and other institutions who render the foregoing services to
their  customers.  The  fees  payable  under  a  Shareholder  Service  Agreement
generally will be calculated at the end of each payment period for each business
day  of the Funds during such period at  the annual rate of 0.25% of the average
daily net  asset  value of  the  Funds'  shares purchased  or  acquired  through
exchange.  Fees calculated in this  manner shall be paid  only to those selected
dealers or other institutions who are  dealers or institutions of record at  the
close  of business on the last business day of the applicable payment period for
the account in which such Fund's shares are held.
    
 
   
Payments pursuant to the Plans are subject to any applicable limitations imposed
by rules of the National Association  of Securities Dealers, Inc. ("NASD").  The
Plans  conform to  rules of the  NASD by  limiting payments made  to dealers and
other  financial  institutions  who  provide  continuing  personal   shareholder
services  to their customers who purchase and own shares of the Funds to no more
than 0.25% per annum of the average  daily net assets of the Funds  attributable
to  the customers of such  dealers or financial institutions,  and by imposing a
cap on the total sales charges, including asset based sales charges, that may be
paid by the Funds and their respective classes.
    
 
   
AIM Distributors does not act as principal,  but rather as agent for the  Funds,
in  making dealer incentive and shareholder  servicing payments under the Plans.
These payments are an obligation of the Funds and not of AIM Distributors.
    
 
   
Prior to  June 1,  1998, the  Trust had  adopted a  different Rule  12b-1,  that
operated  as  a "reimbursement-type"  plan (the  "Prior Plan").  The information
provided below relates to payments made under the Prior Plan, which provided for
payments to GT Global Inc., the distributor  of the Funds at the time the  Prior
Plan was in effect.
    
 
   
For  the  fiscal year  ended December  31,  1997, each  Fund paid  the following
amounts under the Prior Plan:

The Plans require  AIM Distributors to  provide the Board  of Trustees at  least
quarterly  with a written report  of the amounts expended  pursuant to the Plans
and the purposes for  which such expenditures were  made. The Board of  Trustees
reviews  these reports  in connection with  their decisions with  respect to the
Plans.
    
 
   
As required by Rule  12b-1, the Plans and  related forms of Shareholder  Service
Agreements  were approved by the Board of  Trustees, including a majority of the
Trustees who are not "interested  persons" (as defined in  the 1940 Act) of  the
Trust  and who have no direct or indirect financial interest in the operation of
the Plans or in any agreements  related to the Plans ("Qualified Trustees").  In
approving  the  Plans in  accordance with  the requirements  of Rule  12b-1, the
Trustees considered various factors  and determined that  there is a  reasonable
likelihood  that  the Plans  would benefit  each  class of  each Fund  and their
respective shareholders.
    
 
   
The Plans do not obligate the Funds to reimburse AIM Distributors for the actual
expenses AIM  Distributors may  incur in  fulfilling its  obligations under  the
Plans. Thus, even if AIM Distributors' actual expenses exceed the fee payable to
AIM  Distributors thereunder at any given time,  the Funds will not be obligated
to pay more than that fee. If  AIM Distributors' expenses are less than the  fee
it receives, AIM Distributors will retain the full amount of the fee.
    
 
   
Unless  terminated earlier in accordance with their terms, the Plans continue in
effect until  [June  30,  1999]  and  each year  thereafter,  as  long  as  such
continuance is specifically approved at least annually by the Board of Trustees,
including a majority of the Qualified Trustees.
    
 
   
The  Plans  may be  terminated  by the  vote of  a  majority of  the Independent
Trustees, or, with respect to a particular  class, by the vote of a majority  of
the outstanding voting securities of that class.
    
 
   
Any change in the Plans that would increase materially the distribution expenses
paid by the applicable class requires shareholder approval; otherwise, it may be
amended  by the  Trustees, including  a majority  of the  Qualified Trustees, by
votes cast in person  at a meeting  called for the purpose  of voting upon  such
amendment.  As long as the  Plans are in effect,  the selection or nomination of
the Qualified Trustees is committed to the discretion of the Qualified Trustees.
In the event the Class A Plan is amended in a manner which the Board of Trustees
determines would materially increase  the charges paid under  the Class A  Plan,
the  Class B shares of the  Funds will no longer convert  into Class A shares of
the same  Funds unless  the  Class B  shares,  voting separately,  approve  such
amendment.  If the Class B shareholders do not approve such amendment, the Board
of Trustees  will (i)  create  a new  class  of shares  of  the Funds  which  is
identical  in all material respects to the  Class A shares as they existed prior
to the implementation of the amendment and (ii) ensure that the existing Class B
shares of the Funds will be exchanged or converted into such new class of shares
no later than the date the Class B shares were scheduled to convert into Class A
shares.
    
 
   
The principal differences between  the Class A  Plan, on the  one hand, and  the
Class B Plan, on the other hand, are: (i) the Class A Plan allows payment to AIM
Distributors  or to dealers or financial institutions  of up to 0.35% of average
daily net assets of  the Class A shares  of each Fund, as  compared to 1.00%  of
such   assets   of   each   Fund's   Class   B   shares;   (ii)   the   Class  B

Plan obligates  the  Class  B  shares  to  continue  to  make  payments  to  AIM
Distributors  following termination of the Class B shares Distribution Agreement
with respect  to Class  B shares  sold by  or attributable  to the  distribution
efforts  of AIM Distributors unless there has been a complete termination of the
Class B Plan  (as defined in  such Plan) and  (iii) the Class  B Plan  expressly
authorizes AIM Distributors to assign, transfer or pledge its rights to payments
pursuant to the Class B Plan.
    
 
   
                                THE DISTRIBUTOR
    
 
   
Information  concerning  AIM Distributors  and  the continuous  offering  of the
Funds' shares is set forth in the Prospectus under the headings "How to Purchase
Shares" and  "Terms and  Conditions of  Purchase  of the  AIM Funds."  A  Master
Distribution Agreement with AIM Distributors relating to the Class A and Class B
shares  of  the  Funds  was  approved by  the  Board  of  Directors  on Trustees
              , 1998. Both such  Master Distribution Agreements are  hereinafter
collectively referred to as the "Distribution Agreements."
    
 
   
The Distribution Agreements provide that AIM Distributors will bear the expenses
of  printing from the  final proof and distributing  the Funds' prospectuses and
statements of additional information  relating to public  offerings made by  AIM
Distributors   pursuant  to  the  Distribution   Agreements  (other  than  those
prospectuses and statements  of additional information  distributed to  existing
shareholders  of the Fund), and any promotional  or sales literature used by AIM
Distributors or furnished by AIM Distributors to dealers in connection with  the
public  offering  of the  Fund's shares,  including  expenses of  advertising in
connection with such public  offerings. AIM Distributors  has not undertaken  to
sell any specified number of shares of any classes of the Funds.
    
 
   
AIM  Distributors expects  to pay  sales commissions  from its  own resources to
dealers and institutions who  sell Class B  shares of the Funds  at the time  of
such  sales. Payments  with respect  to Class  B shares  will equal  4.0% of the
purchase price of the Class B shares sold by the dealer or institution, and will
consist of a sales commission equal to 3.75% of the purchase price of the  Class
B  shares sold  plus an  advance of  the first  year service  fee of  0.25% with
respect to such shares.  The portion of the  payments to AIM Distributors  under
the  Class  B Plan  which  constitutes an  asset-based  sales charge  (0.75%) is
intended in part to permit  AIM Distributors to recoup  a portion of such  sales
commissions  plus  financing costs.  AIM Distributors  anticipates that  it will
require a  number of  years  to recoup  from Class  B  Plan payments  the  sales
commissions paid to dealers and institutions in connection with sales of Class B
shares.  In  the  future,  if  multiple distributors  serve  a  Fund,  each such
distributor (or  its  assignee or  transferee)  would  receive a  share  of  the
payments  under the  Class B  Plan based on  the portion  of the  Fund's Class B
shares sold by or attributable to the distribution efforts of that distributor.
    
 
   
The Trust (on behalf of any class of any Fund) or AIM Distributors may terminate
the Distribution Agreements on sixty (60) days' written notice without  penalty.
The  Distribution Agreements will terminate automatically  in the event of their
assignment.  In  the  event  the  Class  B  shares  Distribution  Agreement   is
terminated,  AIM Distributors would continue to  receive payments of asset based
distribution fees in respect of the  outstanding Class B shares attributable  to
the distribution efforts of AIM Distributors; provided, however, that a complete
termination  of the Class B  Plan (as defined in  such Plan) would terminate all
payments to AIM Distributors.  Termination of the Class  B Plan or  Distribution
Agreement  does  not  affect the  obligation  of  the Funds  and  their  Class B
shareholders to pay contingent deferred sales charges.
    
 
   
The following chart reflects the total sales charges paid in connection with the
sale of Class A shares of each Fund and the amount retained by GT Global,  Inc.,
the  Trust's  distributor prior  to  June 1,  1998,  for the  fiscal  year ended
December 31, 1997.

TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The  Transfer Agency  and Service  Agreement between  the Trust  and A  I M Fund
Services, Inc. ("AFS"), a registered transfer agent and wholly-owned  subsidiary
of  AIM, provides  that AFS  will perform  certain shareholder  services for the
Funds for a fee per account serviced. The Transfer Agency and Service  Agreement
provides  that AFS will receive a per account fee plus out-of-pocket expenses to
process orders for purchases, redemptions  and exchanges or shares; prepare  and
transmit  payments  for  dividends  and  distributions  declared  by  the Funds;
maintain  shareholder  accounts  and   provide  shareholders  with   information
regarding  the  Funds  and  their  accounts.  The  Transfer  Agency  and Service
Agreement became effective on September 8, 1998. The Sub-adviser also serves  as
each  Fund's pricing and accounting  agent. As of October  31, 1997, October 31,
1996 and  October  31, 1995,  the  Fund paid  accounting  services fees  to  the
Sub-adviser  of Government Income Fund, Strategic  Income Fund, High Income Fund
and Growth  & Income  Fund $85,149,  $127,205, $40,218  and $183,323;  $123,309,
$131,517,  $34,980 and  $162,035; and  $116,607, $101,697,  $22,563 and $40,735,
respectively.
    
 
EXPENSES OF THE FUNDS AND THE PORTFOLIO
   
Each Fund  and  the  Portfolio  pays  all  expenses  not  assumed  by  AIM,  the
Sub-adviser,  AIM  Distributors and  other  agents. These  expenses  include, in
addition to the advisory, distribution, transfer agency, pricing and  accounting
agent  and brokerage fees  discussed above, legal  and audit expenses, custodian
fees, trustees' fees,  organizational fees,  fidelity bond  and other  insurance
premiums,  taxes,  extraordinary  expenses  and  the  expenses  of  reports  and
prospectuses sent  to  existing  investors.  The  allocation  of  general  Trust
expenses and expenses shared by the Funds and other funds organized as series of
the Trust are allocated on a basis deemed fair and equitable, which may be based
on  the relative net assets of the Funds or the nature of the services performed
and relative applicability to each Fund. Expenditures, including costs  incurred
in  connection  with the  purchase or  sale of  portfolio securities,  which are
capitalized  in  accordance  with   generally  accepted  accounting   principles
applicable  to investment companies, are accounted  for as capital items and not
as expenses.  The ratio  of each  Fund's  and the  Portfolio's expenses  to  its
relative  net assets  can be expected  to be  higher than the  expense ratios of
funds investing solely in domestic securities, since the cost of maintaining the
custody of foreign securities and the rate of investment management fees paid by
each Fund and the Portfolio generally are higher than the comparable expenses of
such other funds.
    
 
- --------------------------------------------------------------------------------
 
                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
   
The net asset value per share of  each Fund or Portfolio is normally  determined
daily  as  of the  close  of trading  of the  New  York Stock  Exchange ("NYSE")
(generally 4:00  p.m.  Eastern  time)  on  each business  day  of  the  Fund  or
Portfolio.  In the event the  NYSE closes early (i.e.,  before 4:00 p.m. Eastern
time) on  a particular  day, the  net  asset value  of a  Fund or  Portfolio  is
determined as of the close of the NYSE on such day. Net asset value per share is
determined by dividing the value of the equity securities, cash and other assets
(including  interest  accrued but  not collected)  attributable to  a particular
class, less  all  its  liabilities (including  accrued  expenses  and  dividends
payable)  attributable to that class, by  the total number of shares outstanding
of that class. Determination of each  Fund's or Portfolio's net asset value  per
share is made in accordance with generally accepted accounting principles.
    
 
   
Each  equity security  held is valued  at its  last sales price  on the exchange
where the security is principally traded  or, lacking any sales on a  particular
day, the security is valued at the mean between the closing bid and asked prices
on  that  day. Each  security  traded in  the  over-the-counter market  (but not
including securities reported on the NASDAQ National Market System) is valued at
the mean between the last  bid and asked prices  based upon quotes furnished  by
market makers for

                        AIM GLOBAL GROWTH & INCOME FUND
   
such  securities. Each security reported on the NASDAQ National Market System is
valued at the  last sales price  on the valuation  date or absent  a last  sales
price,  at the mean between  the closing bid and asked  prices on that day. Debt
securities are valued on the basis of prices provided by an independent  pricing
service.  Prices  provided  by the  pricing  service may  be  determined without
exclusive reliance on quoted prices, and may reflect appropriate factors such as
institution-size trading in similar  groups of securities, developments  related
to  special securities,  yield, quality, coupon  rate, maturity,  type of issue,
individual trading characteristics and other  market data. Securities for  which
market  quotations are not  readily available or are  questionable are valued at
fair market value as determined in good faith by or under the supervision of the
Trust's officers in a manner specifically  authorized by the Board of  Trustees.
Short-term  obligations having  60 days  or less to  maturity are  valued on the
basis of amortized cost. For purposes of determining net asset value per  share,
futures  and options  contracts generally  will be  valued 15  minutes after the
close of trading of the NYSE.
    
 
   
Generally, trading  in  foreign  securities, corporate  bonds,  U.S.  Government
securities  and money market instruments is  substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing  the net  asset value  of  each Fund's  or Portfolio's  shares  are
determined  at such  times. Foreign currency  exchange rates  are also generally
determined prior  the close  of  the NYSE.  Occasionally, events  affecting  the
values of such securities and such exchange rates may occur between the times at
which  such values are  determined and the close  of the NYSE  which will not be
reflected in the  computation of  a Fund's or  Portfolio's net  asset value.  If
events  materially  affecting the  value of  such  securities occur  during such
period, then these securities will be  valued at their fair value as  determined
in  good faith by or under the supervision of the Board of Trustees of the Funds
and the Portfolio.

                              HOW TO PURCHASE AND
                                 REDEEM SHARES
    
 
- --------------------------------------------------------------------------------
   
A complete  description of  the  manner in  which shares  of  the Funds  may  be
purchased appears in the Funds' Prospectuses under the headings "How to Purchase
Shares,"  "Terms  and Conditions  of Purchases  of the  AIM Funds"  and "Special
Plans."
    
 
   
The sales charge normally  deducted on purchases  of Class A  shares is used  to
compensate  AIM  Distributors  and  participating  dealers  for  their  expenses
incurred in connections  with the  distribution of  the Funds'  Class A  shares.
Since  there  is  little  expenses  associated  with  unsolicited  orders placed
directly with AIM  Distributors by  persons who, because  of their  relationship
with  the Funds or with AIM and its  affiliates, are familiar with the Funds, or
whose programs for purchase involve little expense (e.g., because of the size of
the transaction  and shareholder  records required),  AIM Distributors  believes
that  it is appropriate and in the  Funds' best interests that such persons, and
certain other  persons whose  purchases  result in  relatively low  expenses  of
distribution,  be permitted to purchase Class A  shares of the Funds through AIM
Distributors without payment  of a sales  charge. The persons  who may  purchase
Class  A shares of the Funds without a  sales charge are set forth in the Funds'
Prospectuses.  In  addition,  the  Funds   offer  programs  such  as  Right   of
Accumulation and Letter of Intent, which are described in the Prospectuses, that
are  designed to permit investors to  aggregate purchases of different funds, or
separate purchases over time, in order to qualify for a lower sales charge rate.
See "Terms and Conditions of Purchase of the AIM Funds -- Reductions in  Initial

Class  B shares will automatically convert into  Class A shares of the same Fund
eight years following  the end of  the calendar  month in which  a purchase  was
made.  For the purpose of calculating the holding period required for conversion
of Class B shares,  the initial issuance  of Class B shares  shall mean (i)  the
date  on which  such Class  B shares  were issued,  or (ii)  for Class  B shares
obtained through an exchange, or  a series of exchanges,  the date on which  the
original  Class B  shares were  issued. For purposes  of conversion  to Class A,
Class B  shares  purchased  through  the reinvestment  of  dividends  and  other
distributions  paid in  respect of  Class B  shares will  be held  in a separate
sub-account. Each time any Class B  shares in the shareholder's regular  account
(other  than those in the sub-account) convert to Class A, a pro rata portion of
the Class B shares in the sub-account will also convert to Class A. The  portion
will be determined by the ratio that the shareholder's Class B shares converting
to  Class A bears to the shareholder's total Class B shares not acquired through
dividends and other distributions.

The availability  of  the  conversion  feature  is  subject  to  the  continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions   paid  on  Class  A  and  Class  B  shares  will  not  result  in
"preferential dividends" under the Internal  Revenue Code and the conversion  of
shares  does not constitute a taxable event. If the conversion feature ceased to

Information concerning  redemption of  the Funds'  shares is  set forth  in  the
Prospectuses under the heading "How to Redeem Shares." In addition to the Funds'
obligation  to redeem shares, AIM Distributors  may also repurchase shares as an
accommodation to shareholders. To  effect a repurchase,  those dealers who  have
executed  Selected Dealer Agreements with AIM  Distributors must phone orders to
the order desk  of the Funds  at (800)  959-4246 and guarantee  delivery of  all
required  documents in  good order.  A repurchase is  effected at  the net asset
value per share  of the  applicable Fund  next determined  after the  repurchase
order  is received. Such  an arrangement is subject  to timely receipt  by A I M
Fund Services, Inc.,  the Funds' transfer  agent, of all  required documents  in
good  order. If such documents  are not received within  a reasonable time after
the order is placed,  the order is  subject to cancellation.  While there is  no
charge  imposed by  a Fund  or by  AIM Distributors  (other than  any applicable
contingent deferred  sales  charge) when  shares  are redeemed  or  repurchased,
dealers may charge a fair service fee for handling the transaction.
    
 
   
The  right of redemption may be suspended  or the date of payment postponed when
(a) trading on  the NYSE is  restricted, as determined  by applicable rules  and
regulations  of the SEC, (b) the NYSE is closed for other than customary weekend

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUNDS
Each Fund is treated as a separate corporation for federal income tax  purposes.
To  continue to qualify for treatment  as a regulated investment company ("RIC")
under the Code, each Fund must  distribute to its shareholders for each  taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income, net short-term capital gain and net gains from certain
foreign  currency  transactions)  ("Distribution  Requirement")  and  must  meet
several additional requirements. With respect  to each Fund, these  requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each  taxable year from dividends, interest, payments with respect to securities
loans and gains  from the  sale or other  disposition of  securities or  foreign
currencies,  or other income  (including gains from  options, Futures or Forward
Contracts) derived with respect  to its business of  investing in securities  or
those currencies ("Income Requirement"); (2) at the close of each quarter of the
Fund's  taxable year,  at least  50% of the  value of  its total  assets must be
represented by cash and  cash items, U.S.  government securities, securities  of
other RICs and other securities, with these other securities limited, in respect
of  any one issuer,  to an amount  that does not  exceed 5% of  the value of the
Fund's total assets and that  does not represent more  than 10% of the  issuer's
outstanding  voting securities;  and (3)  at the  close of  each quarter  of the
Fund's taxable year, not more than 25% of  the value of its total assets may  be
invested  in securities (other than U.S. government securities or the securities
of other RICs) of any  one issuer. The High Income  Fund, as an investor in  the
Portfolio, is deemed to own a proportionate share of the Portfolio's assets, and
to  earn  a  proportionate share  of  the  Portfolio's income,  for  purposes of
determining whether  that Fund  satisfies the  requirements described  above  to
qualify as a RIC.
 
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent  it fails to distribute by the end of any calendar year substantially all
of its  ordinary income  for  that year  and capital  gain  net income  for  the
one-year period ending on October 31 of that year, plus certain other amounts.
 
See  "Taxation of Certain  Investment Activities" below for  a discussion of the
tax consequences to the High Income Fund of hedging transactions engaged in, and
investments in passive foreign investment companies ("PFICs") and other  foreign
securities by, the Portfolio.
 
TAXATION OF THE PORTFOLIO -- GENERAL
The Portfolio is treated as a partnership for federal income tax purposes and is
not  a "publicly traded partnership." As a  result, the Portfolio is not subject
to federal income  tax; instead, the  High Income  Fund, as an  investor in  the
Portfolio,  is required to  take into account in  determining its federal income
tax  liability   its   share  of   the   Portfolio's  income,   gains,   losses,

                           AIM STRATEGIC INCOME FUND
                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
deductions  and  credits, without  regard to  whether it  has received  any cash
distributions from the Portfolio. The Portfolio also is not subject to  Delaware
income or franchise tax.
 
Because,  as noted above, the High Income  Fund is deemed to own a proportionate
share of  the Portfolio's  assets, and  to  earn a  proportionate share  of  the
Portfolio's  income, for purposes of determining whether that Fund satisfies the
requirements to  qualify  as  a  RIC,  the  Portfolio  intends  to  conduct  its
operations  so that the High Income Fund will be able to continue to satisfy all
those requirements.
 
Distributions to the High Income Fund from the Portfolio (whether pursuant to  a
partial  or complete  withdrawal or  otherwise) will  not result  in that Fund's
recognition of any gain or loss for federal income tax purposes, except that (1)
gain will be recognized to the extent any cash that is distributed exceeds  that
Fund's  basis for  its interest  in the  Portfolio before  the distribution, (2)
income or gain will be recognized if the distribution is in liquidation of  that
Fund's entire interest in the Portfolio and includes a disproportionate share of
any  unrealized  receivables  held  by  the  Portfolio,  and  (3)  loss  will be
recognized  if  a  liquidation  distribution  consists  solely  of  cash  and/or
unrealized  receivables. The  High Income Fund's  basis for its  interest in the
Portfolio generally will equal the amount of cash and the basis of any  property
that  Fund  invests in  the Portfolio,  increased  by that  Fund's share  of the
Portfolio's net income and gains and decreased by (a) the amount of cash and the
basis of any property the Portfolio distributes to that Fund and (b) that Fund's
share of the Portfolio's losses.
 
TAXATION OF CERTAIN INVESTMENT ACTIVITIES
   
For purposes of the following discussion, "Investor Funds" means the  Government
Income  Fund,  the Strategic  Income  Fund, the  Growth  & Income  Fund  and the
Portfolio.
    
 
   
    FOREIGN TAXES.  Interest and  dividends received  by an  Investor Fund,  and
gains  realized thereby,  may be subject  to income, withholding  or other taxes
imposed by foreign countries and  U.S. possessions ("foreign taxes") that  would
reduce  the yield and/or total return on its securities. Tax conventions between
certain countries and the United States  may reduce or eliminate foreign  taxes,
however,  and many  foreign countries  do not impose  taxes on  capital gains in
respect of investments by foreign investors. If more than 50% of the value of an
Investor Fund's  total assets  (taking into  account, in  the case  of the  High
Income  Fund, its proportionate share of the Portfolio's assets) at the close of
its taxable year consists of securities  of foreign corporations, the Fund  will
be eligible to, and may, file an election with the Internal Revenue Service that
will  enable its shareholders, in effect, to  receive the benefit of the foreign
tax credit with respect to any foreign taxes paid by it (taking into account, in
the case of the High Income Fund,  its proportionate share of any foreign  taxes
paid  by the Portfolio) (a "Fund's foreign taxes"). Pursuant to the election, an
Investor Fund would treat those taxes as dividends paid to its shareholders  and
each  shareholder would be required to (1) include in gross income, and treat as
paid by him, his proportionate share of the Fund's foreign taxes, (2) treat  his
share  of those taxes and  of any dividend paid by  the Fund that represents its
income from foreign and  U.S. possessions sources (taking  into account, in  the
case  of the High Income Fund, its proportionate share of the Portfolio's income
from those sources) as his own income  from those sources and (3) either  deduct
the  taxes deemed paid by him in computing his taxable income or, alternatively,
use the foregoing information in calculating the foreign tax credit against  his
federal  income tax. Each Investor Fund  will report to its shareholders shortly
after each taxable year their respective shares of the Fund's foreign taxes  and
income  (taking  into  account,  in  the  case  of  the  High  Income  Fund, its
proportionate share  of  the Portfolio's  income)  from sources  within  foreign
countries  and  U.S. possessions  if  it makes  this  election. Pursuant  to the
Taxpayer Relief Act of 1997 ("Tax Act"), individuals who have no more than  $300
($600  for married persons filing jointly)  of creditable foreign taxes included
on Form  1099 and  all of  whose  foreign source  income is  "qualified  passive
income"  may elect each year to be exempt from the extremely complicated foreign
tax credit limitation and  will be able  to claim a  foreign tax credit  without
having to file the detailed Form 1116 that otherwise is required.
    
 
   
    PASSIVE  FOREIGN INVESTMENT COMPANIES. Each Investor  Fund may invest in the
stock of PFICs.  A PFIC is  a foreign  corporation -- other  than a  "controlled
foreign  corporation" (I.E., a  foreign corporation in which,  on any day during
its taxable year, more than  50% of the total voting  power of all voting  stock
therein  or the total value of all  stock therein is owned, directly, indirectly
or  constructively,  by  "U.S.  shareholders,"  defined  as  U.S.  persons  that
individually  own, directly, indirectly or constructively,  at least 10% of that
voting power) as  to which the  Investor Fund is  a U.S. shareholder  (effective
with  respect to each Investor  Fund for its taxable  year beginning November 1,
1998) -- that, in general, meets either of the following tests: (1) at least 75%
of its gross income is passive or (2)  an average of at least 50% of its  assets
produce,  or  are held  for  the production  of,  passive income.  Under certain
circumstances, an Investor Fund will be subject to federal income tax on a  part
(or,  in the case of the High Income Fund, its proportionate share of a part) of
any "excess

distribution" received by it (or,  in the case of the  High Income Fund, by  the
Portfolio)  on the stock of a PFIC or of any gain on the Fund's (or, in the case
of  the  High  Income   Fund,  the  Portfolio's)   disposition  of  that   stock
(collectively   "PFIC  income"),  plus  interest   thereon,  even  if  the  Fund
distributes the  PFIC income  as a  taxable dividend  to its  shareholders.  The
balance  of the PFIC  income will be  included in the  Fund's investment company
taxable income and,  accordingly, will not  be taxable  to it to  the extent  it
distributes that income to its shareholders.
    
 
If  an  Investor Fund  invests in  a  PFIC and  elects to  treat  the PFIC  as a
"qualified electing  fund"  ("QEF"), then  in  lieu  of the  foregoing  tax  and
interest  obligation, the Investor Fund  (or, in the case  of the Portfolio, the
High Income Fund) would be required to include in income each year its pro  rata
share  (taking  into  account,  in  the  case  of  the  High  Income  Fund,  its
proportionate share of  the Portfolio's pro  rata share) of  the QEF's  ordinary
earnings  and net capital gain  (I.E., the excess of  net long-term capital gain
over net  short-term  capital  loss) --  which  most  likely would  have  to  be
distributed  by the Investor  Fund (or, in  the case of  the Portfolio, the High
Income Fund) to satisfy the Distribution Requirement and avoid imposition of the
Excise Tax -- even if those earnings and gain were not received thereby from the
QEF. In most instances  it will be  very difficult, if  not impossible, to  make
this election because of certain requirements thereof.
 
   
Effective  for its taxable  year beginning November 1,  1998, each Investor Fund
may elect to  "mark to market"  its stock in  any PFIC. "Marking-to-market,"  in
this  context, means including in ordinary  income each taxable year the excess,
if any, of the fair market value  of the stock over an Investor Fund's  adjusted
basis  therein as of the end of that year. Pursuant to the election, an Investor
Fund also will  be allowed to  deduct (as  an ordinary, not  capital, loss)  the
excess,  if any, of its adjusted basis in  PFIC stock over the fair market value
thereof as  of  the  taxable  year-end,  but only  to  the  extent  of  any  net
mark-to-market  gains with respect to that stock  included in income by the Fund
for prior taxable years. An Investor Fund's adjusted basis in each PFIC's  stock
subject  to  the election  will be  adjusted  to reflect  the amounts  of income
included and deductions taken thereunder. Regulations proposed in 1992  provided
a similar election with respect to the stock of certain PFICs.
    
 
    OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. The Investors Funds' use
of  hedging transactions, such  as selling (writing)  and purchasing options and
Futures Contracts and  entering into Forward  Contracts, involves complex  rules
that  will determine, for federal income tax purposes, the amount, character and
timing of  recognition of  the gains  and losses  an Investor  Fund realizes  in
connection  therewith. Gains from the  disposition of foreign currencies (except
certain gains  that may  be  excluded by  future  regulations), and  gains  from
options,  Futures and Forward Contracts derived by an Investor Fund with respect
to its business of investing in  securities or foreign currencies, will  qualify
as  permissible income under the Income  Requirement for that Investor Fund (or,
in the case of the Portfolio, the High Income Fund).
 
Futures and  Forward Contracts  that are  subject to  Section 1256  of the  Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts") and that are held by an Investor Fund at the end of its taxable year
generally will be  deemed to have  been sold at  that time at  market value  for
federal income tax purposes. Sixty percent of any net gain or loss recognized on
these  deemed sales, and  60% of any net  gain or loss  realized from any actual
sales of Section 1256  Contracts, will be treated  as long-term capital gain  or
loss,  and the balance will be treated  as short-term capital gain or loss. That
60% portion  will qualify  for the  reduced maximum  tax rates  on  noncorporate
taxpayers'  net capital gain enacted by the Tax Act -- 20% (10% for taxpayers in
the 15% marginal  tax bracket) for  gain recognized on  capital assets held  for
more  than  18  months  --  instead  of  the  28%  rate  in  effect  before that
legislation, which now  applies to gain  recognized on capital  assets held  for
more than one year but not more than 18 months.
 
Section  988 of the Code also may apply to gains and losses from transactions in
foreign currencies,  foreign-currency-denominated debt  securities and  options,
Futures  and Forward  Contracts on foreign  currencies ("Section  988" gains and
losses). Each Section  988 gain  or loss  generally is  computed separately  and
treated as ordinary income or loss. In the case of overlap between sections 1256
and  988, special provisions  determine the character and  timing of any income,
gain or loss. Each Investor Fund attempts to monitor section 988 transactions to
minimize any adverse tax impact.
 
   
If an Investor  Fund has an  "appreciated financial position"  -- generally,  an
interest  (including an interest through an  option, Futures or Forward Contract
or short sale) with respect to any stock, debt instrument (other than  "straight
debt")  or  partnership interest  the  fair market  value  of which  exceeds its
adjusted basis  --  and  enters  into  a "constructive  sale"  of  the  same  or
substantially  similar  property, the  Fund will  be treated  as having  made an
actual sale thereof, with the result that gain will be recognized at that  time.
A  constructive sale generally consists of  a short sale, an offsetting notional
principal contract or Futures  or Forward Contract entered  into by an  Investor
Fund or a related person with respect to the

same  or  substantially  similar  property.  In  addition,  if  the  appreciated
financial position is itself a short sale or such a contract, acquisition of the
underlying  property  or  substantially  similar  property  will  be  deemed   a
constructive sale.
 
   
The  Strategic Income  Fund and  the Portfolio each  may acquire  zero coupon or
other securities issued  with original issue  discount ("OID"). As  a holder  of
those  securities, that Fund and the Portfolio (and, through it, the High Income
Fund) each must include in its income the portion of the OID that accrues on the
securities during the taxable year, even if no corresponding payment on them  is
received during the year. Similarly, the Strategic Income Fund and the Portfolio
each  must include in its  gross income securities it  receives as "interest" on
payment-in-kind  securities.  Because   each  Fund   annually  must   distribute
substantially  all of its  investment company taxable  income, including any OID
and other non-cash  income, to  satisfy the Distribution  Requirement and  avoid
imposition of the Excise Tax, the Strategic Income Fund or the High Income Fund,
or  both, may be  required in a particular  year to distribute  as a dividend an
amount that is greater than the total  amount of cash it actually receives  (or,
in  the case of the High Income Fund, its  share of the total amount of cash the
Portfolio actually receives). Those distributions  will be made from the  Fund's
(or,  in the case of the High Income Fund, its, or its share of the Portfolio's)
cash  assets  or,  if  necessary,  from  the  proceeds  of  sales  of  portfolio
securities.  Such Fund may  (directly or through  the Portfolio) realize capital
gains or  losses  from  those  sales,  which  would  increase  or  decrease  its
investment company taxable income and/or net capital gain.
    
 
TAXATION OF THE FUNDS' SHAREHOLDERS
Dividends  and  other  distributions  declared  by a  Fund  in,  and  payable to
shareholders of record as  of a date  in, October, November  or December of  any
year  will  be  deemed  to have  been  paid  by  the Fund  and  received  by the
shareholders on December 31 of  that year if the  distributions are paid by  the
Fund  during  the following  January. Accordingly,  those distributions  will be
taxed to shareholders for the year in which that December 31 falls.
 
   
A portion of the  dividends from the Growth  & Income Fund's investment  company
taxable  income (whether paid in cash or reinvested in additional shares) may be
eligible for  the  dividends-received  deduction allowed  to  corporations.  The
eligible  portion may not  exceed the aggregate dividends  received by that Fund
from U.S. corporations. However, dividends  received by a corporate  shareholder
and  deducted by  it pursuant  to the  dividends-received deduction  are subject
indirectly to the  federal alternative  minimum tax.  The Funds  other than  the
Growth  &  Income Fund  are  not expected  to  pay dividends  eligible  for that
deduction.
    
 
If Fund shares are sold at a loss  after being held for six months or less,  the
loss  will be treated as  long-term, instead of short-term,  capital loss to the
extent of any  capital gain  distributions received on  those shares.  Investors
also should be aware that if shares are purchased shortly before the record date
for  any dividend or other distribution, the shareholder will pay full price for
the shares and receive some portion of the price back as a taxable distribution.
 
Dividends paid by a  Fund to a shareholder  who, as to the  United States, is  a
nonresident  alien individual, nonresident alien fiduciary of a trust or estate,
foreign corporation  or foreign  partnership ("foreign  shareholder")  generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding  will not apply, however, to a dividend  paid by a Fund to a foreign
shareholder that is "effectively connected with  the conduct of a U.S. trade  or
business,"  in which case the  reporting and withholding requirements applicable
to domestic shareholders  will apply. A  distribution of net  capital gain by  a
Fund  to a foreign shareholder generally will  be subject to U.S. federal income
tax (at the rates  applicable to domestic persons)  only if the distribution  is
"effectively  connected" or  the foreign  shareholder is  treated as  a resident
alien individual for federal income tax purposes.
 
The foregoing  is a  general  and abbreviated  summary  of certain  federal  tax
considerations  affecting  the  Funds,  their  shareholders  and  the Portfolio.
Investors are  urged  to  consult  their own  tax  advisers  for  more  detailed
information  and for  information regarding any  foreign, state  and local taxes
applicable to distributions received from a Fund.

SHAREHOLDER LIABILITY
    
   
Under  Delaware law,  the shareholders of  the Trust enjoy  the same limitations
extended to shareholders of private, for-profit corporations. There is a  remote
possibility, however, that under certain circumstances shareholders of the Trust
may  be held personally  liable for the Trust's  obligations. However, the Trust
Agreement disclaims shareholder liability for  acts or obligations of the  Trust
and  requires  that  notice  of  such disclaimer  be  given  in  each agreement,
obligation or instrument entered into or executed by the Trust or a trustee. The
Trust Agreement provides  for indemnification  from the Trust  property for  all
losses  and expenses of  any shareholder held personally  liable for the Trust's
obligations. Thus, the risk of a shareholder incurring financial loss on account
of such liability is limited to circumstances in which the Trust itself would be
unable to meet  its obligations and  where the other  party was held  not to  be
bound by the disclaimer.

TOTAL RETURN QUOTATIONS
    
   
The  standard  formula  for  calculating  total  return,  as  described  in  the
Prospectus, is as follows:
    
 
   
                          P(1+T)to the power of n=ERV
    
 
   
<TABLE>
<S>        <C>        <C>
Where      P    =     a hypothetical initial payment of $1,000.
           T    =     average annual total return (assuming the applicable maximum sales load is deducted at the
                      beginning of the 1, 5, or 10 year periods).
           n    =     number of years.
           ERV =      ending redeemable value of a hypothetical $1,000 payment at the end of the 1, 5, or 10 year
                      periods (or fractional portion of such period).

NON-STANDARDIZED RETURNS
   
Standard total  return  quotes  may  be  accompanied  by  total  return  figures

be calculated without assuming payment of  the full sales load according to  the
following formula:
    
 
   
                          P(1+U)to the power of n=ERV

                      applicable maximum sales load at the beginning of the stated period.
           n    =     number of years.
           ERV =      ending redeemable value of a hypothetical $1,000 payment at the end of the stated period.

YIELD QUOTATIONS
    
   
The  standard formula for calculating  yield for each Fund,  as described in the
Prospectus, is as follows:
    
 
   
              YIELD  =  2[((a-b)/(c x d) + 1)to the power of 6-1]

Where      a    =     dividends and interest earned during a stated 30-day period. For purposes of this
                      calculation, dividends are accrued rather than recorded on the ex-dividend date. Interest
                      earned under this formula must generally be calculated based on the yield to maturity of
                      each obligation (or, if more appropriate, based on yield to call date).
           b    =     expenses accrued during period (net of reimbursement).
           c    =     the average daily number of shares outstanding during the period.
           d    =     the maximum offering price per share on the last day of the period.

                          DESCRIPTION OF DEBT RATINGS
    
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S  INVESTORS SERVICE, INC. rates the debt securities issued by various
entities from  "Aaa"  to  "C".  Investment grade  ratings  are  the  first  four
categories:
 
        Aaa  -- Bonds which are rated Aaa are  judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt  edged." Interest payments  are protected  by a large  or by  an
    exceptionally  stable  margin and  principal  is secure.  While  the various
    protective elements are likely to change, such changes as can be  visualized
    are  most  unlikely  to impair  the  fundamentally strong  position  of such
    issues.
 
        Aa -- Bonds which are rated Aa are  judged to be of high quality by  all
    standards.  Together with  the Aaa  group they  comprise what  are generally
    known as high grade bonds. They are rated lower than the best bonds  because
    margins  of  protection  may  not  be  as  large  as  in  Aaa  securities or
    fluctuation of protective elements may be of greater amplitude or there  may
    be  other elements  present which  make the  long-term risk  appear somewhat
    larger than the Aaa securities.
 
        A  --  Bonds  which  are  rated  A  possess  many  favorable  investment
    attributes  and  are  to be  considered  as  upper-medium-grade obligations.
    Factors giving security to principal  and interest are considered  adequate,
    but  elements may  be present which  suggest a  susceptibility to impairment
    some time in the future.
 
        Baa --  Bonds  which  are  rated  Baa  are  considered  as  medium-grade
    obligations,  (i.e., they are neither  highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective  elements may  be lacking  or may  be  characteristically
    unreliable  over  any  great length  of  time. Such  bonds  lack outstanding
    investment characteristics and in  fact have speculative characteristics  as
    well.
 
        Ba  -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered  as well-assured. Often the protection  of
    interest  and principal payments may be  very moderate, and thereby not well
    safeguarded during both good and bad  times over the future. Uncertainty  of
    position characterizes bonds in this class.
 
        B  --  Bonds which  are rated  B generally  lack characteristics  of the
    desirable investment. Assurance  of interest  and principal  payments or  of
    maintenance  of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa  are of poor standing. Such issues  may
    be  in default or  there may be  present elements of  danger with respect to
    principal or interest.
 
        Ca  --  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C  -- Bonds which are  rated C are the lowest  rated class of bonds, and
    issues so rated can be regarded  as having extremely poor prospects of  ever
    attaining any real investment standing.
 
ABSENCE  OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may  be for reasons unrelated  to the quality of  the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
     1. An application for rating was not received or accepted.
 
     2.  The issue or issuer belongs to  a group of securities or companies that
are not rated as a matter of policy.
 
     3. There is a lack of essential data pertaining to the issue or issuer.
 
     4. The  issue  was  privately placed,  in  which  case the  rating  is  not
published in Moody's publications.

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
 
Suspension  or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data  to permit  a judgment  to be  formed; if  a bond  is
called for redemption; or for other reasons.
 
Note:  Moody's applies numerical modifiers,  1, 2, and 3  in each generic rating
classification from Aa to Caa. The  modifier 1 indicates that the Company  ranks
in  the higher end  of its generic  rating category; the  modifier 2 indicates a
mid-range ranking; and the  modifier 3 indicates that  the Company ranks in  the
lower end of its generic rating category.
 
    STANDARD  & POOR'S, a division of The McGraw-Hill Companies, Inc., rates the
securities debt of  various entities  in categories  ranging from  "AAA" to  "D"
according to quality. Investment grade ratings are the first four categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA   --  An  obligation  rated  "AA"  differs  from  the  highest  rated
    obligations only  in a  small degree.  The obligor's  capacity to  meet  its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB   --  An   obligation  rated  "BBB"   exhibits  adequate  protection
    parameters. However, adverse economic  conditions or changing  circumstances
    are  more likely to lead  to a weakened capacity of  the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and  "C"
    are   regarded  as  having  significant  speculative  characteristics.  "BB"
    indicates the least degree  of speculation and "C"  the highest. While  such
    obligations  will likely  have some quality  and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An  obligation rated "BB"  is less vulnerable  to nonpayment  than
    other  speculative issues. However, it  faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which  could
    lead  to the obligor's inadequate capacity  to meet its financial commitment
    on the obligation.
 
        B --  An obligation  rated "B"  is more  vulnerable to  nonpayment  than
    obligations  rated "BB," but the obligor  currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial,  or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC  -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its  financial commitment on the obligation. In  the
    event of adverse business, financial, or economic conditions, the obligor is
    not  likely to  have the  capacity to meet  its financial  commitment on the
    obligation.
 
        CC --  An  obligation  rated  "CC" is  currently  highly  vulnerable  to
    nonpayment.
 
        C  -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed  or similar action has  been taken, but payments  on
    this obligation are being continued.
 
        D  -- An  obligation rated  "D" is  in payment  default. The  "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the  applicable grace period  has not expired,  unless S&P  believes
    that  such payments will  be made during  such grace period.  The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking  of
    a similar action if payments on an obligation are jeopardized.
 
PLUS  (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by the
addition of a  plus or minus  sign to  show relative standing  within the  major
rating categories.
 
NR:  Indicates that  no rating  has been  requested, that  there is insufficient
information on which to base  a rating, or that S&P  does not rate a  particular
type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S  employs  the  designation "Prime-1"  to  indicate  commercial paper
having a superior ability for  repayment of senior short-term debt  obligations.
Prime-1  repayment  ability will  often be  evidenced by  many of  the following
characteristics: leading market positions  in well-established industries;  high
rates of return on funds employed; conservative

                        AIM GLOBAL GROWTH & INCOME FUND
capitalization  structure  with  moderate  reliance  on  debt  and  ample  asset
protection; broad margins in  earnings coverage of  fixed financial charges  and
high  internal  cash  generation;  and well-established  access  to  a  range of
financial markets  and  assured sources  of  alternate liquidity.  Issues  rated
Prime-2   have  a  strong  ability  for  repayment  of  senior  short-term  debt
obligations. This  normally will  be evidenced  by many  of the  characteristics
cited  above but to a lesser degree.  Earnings trends and coverage ratios, while
sound, may be more subject  to variation. Capitalization characteristics,  while
still  appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.
 
    S&P ratings of commercial paper  are graded into several categories  ranging
from  "A1" for the highest quality obligations  to "D" for the lowest. Issues in
the "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate  the
relative  degree  of safety.  A-1 --  This highest  category indicates  that the
degree of safety regarding timely payment is strong. Those issues determined  to
possess extremely strong safety characteristics will be denoted with a plus sign
(+)  designation.  A-2  -- Capacity  for  timely  payments on  issues  with this
designation is satisfactory; however,  the relative degree of  safety is not  as
high as for issues designated "A-1."

                                  INTRODUCTION
    
 
- --------------------------------------------------------------------------------
 
   
This  Statement of Additional Information relates to the Advisor Class shares of
AIM Developing Markets  Fund ("Developing Markets  Fund"), AIM Emerging  Markets
Fund  ("Emerging  Markets Fund"),  and AIM  Latin  American Growth  Fund ("Latin
American Fund")  (each, a  "Fund," and  collectively, the  "Funds").  Developing
Markets  Fund and  Latin American Fund  each is a  non-diversified, and Emerging
Markets Fund is a diversified, series  of AIM Investment Funds (the "Trust"),  a
registered  open-end  management  investment  company  organized  as  a Delaware
business trust. On October 31, 1997,  the Developing Markets Fund, which had  no
prior operating history, acquired the assets and assumed the liabilities of G.T.
Global  Developing  Markets Fund,  Inc. (the  "Predecessor Fund"),  a closed-end
investment company.
    
 
   
A  I  M  Advisors,  Inc.  ("AIM")  serves  as  the  investment  manager  of  and
administrator  for, and  INVESCO (NY),  Inc. (the  "Sub-adviser") serves  as the
investment sub-adviser and sub-administrator for the Funds.
    
 
   
The Trust is  a series  mutual fund.  The rules  and regulations  of the  United
States  Securities and Exchange Commission (the  "SEC") require all mutual funds
to furnish prospective investors  certain information concerning the  activities
of  the fund  being considered for  investment. This  information for Developing
Markets Fund is included in a  separate Prospectus dated September 8, 1998,  for
Emerging  Markets Fund is  included in a separate  Prospectus dated September 8,
1998 and for  Latin American  Fund is included  in a  separate Prospectus  dated
September  8, 1998. Additional copies of  the Prospectuses and this Statement of
Additional Information may be obtained  without charge by writing the  principal
distributor of the Funds' shares, A I M Distributors, Inc. ("AIM Distributors"),
P.O.  Box 4739, Houston,  TX 77210-4739 or by  calling (800) 347-4246. Investors
must receive a Prospectus before they invest.
    
 
   
This Statement  of Additional  Information is  intended to  furnish  prospective
investors  with  additional  information  concerning  the  Funds.  Some  of  the
information required to be in this  Statement of Additional Information is  also
included in the Prospectus; and, in order to avoid repetition, reference will be
made  to  sections  of the  Prospectus.  Additionally, the  Prospectus  and this
Statement of Additional  Information omit certain  information contained in  the
Registration Statement filed with the SEC. Copies of the Registration Statement,
including  items omitted  from the Prospectus  and this  Statement of Additional
Information, may be obtained from the SEC by paying the charges prescribed under
its rules and regulations.
    
 
   
                      GENERAL INFORMATION ABOUT THE FUNDS
    
 
   
THE TRUST AND ITS SHARES
    
 
   
The Trust previously operated under the name G.T. Investment Funds, Inc.,  which
was  organized as  a Maryland  corporation on  October 29,  1987. The  Trust was
reorganized on September 4, 1998 as a Delaware business trust, and is registered
with the SEC as a diversified open-end series management investment company. The
Trust currently consists of thirteen  separate portfolios, AIM Global  Financial
Services  Fund, AIM Global  Infrastructure Fund, AIM  Global Resources Fund, AIM
Global Consumer  Products and  Services Fund,  AIM Global  Healthcare Fund,  AIM
Global  Telecommunications Fund, AIM  Global Government Income  Fund, AIM Global
High Income Fund, AIM Strategic Income Fund, AIM Global Growth and Income  Fund,
AIM  Emerging Markets Fund, AIM Developing  Markets Fund, and AIM Latin American
Growth Fund. Each of these  funds has three separate  classes: Class A, Class  B
and  Advisor  Class  shares.  All  historical  financial  and  other information
contained in  this Statement  of  Additional Information  for periods  prior  to
September 4, 1998, is that of the series of G.T. Investment Funds, Inc. (renamed
AIM Investment Funds, Inc.)
    
 
   
This  Statement of  Additional Information relates  solely to  the Advisor Class
shares of the Fund.
    
 
   
The term "majority of the outstanding shares" of the Trust, a particular Fund or
a particular class of a Fund means, respectively, the vote of the lesser of  (a)
67%  or more of the  shares of the Trust,  such Fund or such  class present at a
meeting of the  Trust's shareholders, if  the holders  of more than  50% of  the
outstanding  shares  of  the Trust,  such  Fund  or such  class  are  present or
represented by proxy,  or (b) more  than 50%  of the outstanding  shares of  the
Trust, such Fund or such class.

                          AIM DEVELOPING MARKETS FUND
                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
   
Class  A, Class B  and Advisor Class shares  of each Fund  have equal rights and
privileges. Each  share  of a  particular  class is  entitled  to one  vote,  to
participate equally in dividends and distributions declared by the Trust's Board
of  Trustees with respect to the class of such Fund and, upon liquidation of the
Fund, to participate proportionately in the net assets of the Fund allocable  to
such  class remaining after satisfaction of  outstanding liabilities of the Fund
allocable to such class.  Fund shares are fully  paid, non-assessable and  fully
transferable  when issued and have no preemptive rights and have such conversion
and exchange  rights  as set  forth  in the  Prospectus  and this  Statement  of
Additional  Information. Fractional shares have proportionately the same rights,
including voting rights, as are provided for a full share.
    
 
   
Shareholders of the Funds  do not have cumulative  voting rights, and  therefore
the  holders of  more than  50% of  the outstanding  shares of  all Funds voting
together for election of directors may elect all of the members of the Board  of
Trustees  of the Trust.  In such event,  the remaining holders  cannot elect any
trustees of the Trust.

                           INVESTMENT OBJECTIVES AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
INVESTMENT OBJECTIVES
    DEVELOPING MARKETS FUND.   The  primary investment  objective of  Developing
Markets  Fund  is  long-term  capital  appreciation.  Its  secondary  investment
objective is income, to the extent consistent with seeking capital appreciation.
The Fund normally  invests substantially  all of its  assets in  issuers in  the
developing (or "emerging") markets of Asia, Europe, Latin America and elsewhere.
The  Fund  does not  consider the  following countries  to be  emerging markets:
Australia, Austria, Belgium, Canada, Denmark, England, Finland, France, Germany,
Ireland, Italy,  Japan, the  Netherlands, New  Zealand, Norway,  Spain,  Sweden,
Switzerland and the United States.
 
    EMERGING  MARKETS FUND. The investment objective of Emerging Markets Fund is
long-term growth of capital. The Fund  seeks this objective by investing,  under
normal  circumstances, at least 65% of its  total assets in equity securities of
companies in  emerging  markets.  The  Fund  does  not  consider  the  following
countries  to be emerging markets: Australia, Austria, Belgium, Canada, Denmark,
England, Finland, France, Germany, Ireland,  Italy, Japan, the Netherlands,  New
Zealand, Norway, Spain, Sweden, Switzerland and United States. The Fund normally
may  invest up to 35% of  its assets in a combination  of (i) debt securities of
government or  corporate  issuers in  emerging  markets; (ii)  equity  and  debt
securities of issuers in developed countries, including the United States; (iii)
securities  of issuers in emerging markets not  included in the list of emerging
markets set forth in the Fund's current Prospectus, if investing therein becomes
feasible and desirable subsequent to the date of the Fund's current  Prospectus;
and (iv) cash and money market instruments.
 
In  determining  what  countries  constitute emerging  markets  with  respect to
Developing Market Fund and Emerging Markets Fund, the Sub-adviser will consider,
among other things, data, analysis, and classification of countries published or
disseminated by  the  International  Bank  for  Reconstruction  and  Development
(commonly  known as  the World Bank)  and the  International Finance Corporation
("IFC").
 
    LATIN AMERICAN  FUND. The  investment objective  of Latin  American Fund  is
capital  appreciation. The Fund will  normally invest at least  65% of its total
assets in securities of a broad  range of Latin American issuers. Under  current
market  conditions,  the Fund  expects to  invest primarily  in equity  and debt
securities issued  by companies  and governments  in Mexico,  Chile, Brazil  and
Argentina.  Though the Fund can normally invest up to 35% of its total assets in
U.S. securities, the Fund  reserves the right to  be primarily invested in  U.S.
securities  for  temporary  defensive  purposes  or  pending  investment  of the
proceeds of the offering made hereby.
 
SELECTION OF EQUITY INVESTMENTS
In  determining  the  appropriate  distribution  of  investments  among  various
countries  and  geographic regions  for  the Funds,  the  Sub-adviser ordinarily
considers the following  factors: prospects for  relative economic growth  among
the  different  countries  in  which  a  Fund  may  invest;  expected  levels of
inflation; government policies influencing business conditions; the outlook  for
currency relationships; and the range of the individual investment opportunities
available to international investors.
 
                   Statement of Additional Information Page 4
<PAGE>
                          AIM DEVELOPING MARKETS FUND
                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
In  analyzing companies for investment by  each Fund, the Sub-adviser ordinarily
looks for  one  or  more  of the  following  characteristics:  an  above-average
earnings  growth per  share; high  return on  invested capital;  healthy balance
sheet; sound financial and accounting  policies and overall financial  strength;
strong  competitive advantages;  effective research and  product development and
marketing; efficient service; pricing  flexibility; strength of management;  and
general  operating characteristics  which will  enable the  companies to compete
successfully  in   their   respective  marketplaces.   In   certain   countries,
governmental  restrictions and  other limitations  on investment  may affect the
maximum percentage  of equity  ownership in  any one  company by  the Funds.  In
addition,  in some instances only special classes of securities may be purchased
by foreigners and the market prices, liquidity and rights with respect to  those
securities may vary from shares owned by nationals.
 
   
Although  the Funds value their assets daily in terms of U.S. dollars, the Funds
do not intend to convert their holdings of foreign currencies into U.S.  dollars
on  a daily basis. The Funds will do  so from time to time, and investors should
be aware of the costs of currency conversion. Although foreign exchange  dealers
do  not charge  a fee  for conversion,  they do  realize a  profit based  on the
difference ("spread") between the  prices at which they  are buying and  selling
various  currencies. Thus, a dealer may offer  to sell a foreign currency to the
Funds at one rate, while offering a lesser rate of exchange should a Fund desire
to sell that currency to the dealer.
    
 
There may be times when, in  the opinion of the Sub-adviser, prevailing  market,
economic  or political conditions warrant reducing the proportion of each Fund's
assets invested in equity securities and increasing the proportion held in  cash
or  short-term obligations  denominated in U.S.  dollars or  other currencies. A
portion of  each  Fund's  assets may  be  held  in U.S.  dollars  or  short-term
interest-bearing  dollar-denominated securities to  provide for ongoing expenses
and redemptions.
 
   
The Funds may be prohibited under the Investment Company Act of 1940, as amended
("1940 Act"), from purchasing the securities of any foreign company that, in its
most recent  fiscal year,  derived more  than  15% of  its gross  revenues  from
securities-related  activities ("securities-related companies").  In a number of
countries, including those in Latin America, commercial banks act as  securities
broker/dealers,  investment  advisers and  underwriters  or otherwise  engage in
securities-related activities,  which  may  limit the  Fund's  ability  to  hold
securities  issued by such  banks. The Fund  has obtained an  exemption from the
Securities and Exchange Commission ("SEC") to permit it to invest in certain  of
these securities subject to certain restrictions.
    
 
For  investment  purposes, an  issuer is  typically considered  as located  in a
particular country  if it  (a) is  incorporated under  the laws  of or  has  its
principal  office in that country, or (b) it normally derives 50% or more of its
total revenue from  business in that  country. However, these  are not  absolute
requirements,  and certain  companies incorporated  in a  particular country and
considered by the Sub-adviser to be located in that country may have substantial
off-shore operations or subsidiaries and/or  export sales exceeding in size  the
assets or sales in that country.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
The  Funds  may  invest in  the  securities of  investment  companies (including
investment vehicles or companies  advised by the  Sub-adviser or its  affiliates
("Affiliated  Funds"))  within the  limits of  the  1940 Act.  These limitations
currently provide  that,  in  general,  each  Fund  may  purchase  shares  of  a
closed-end investment company unless (a) such a purchase would cause the Fund to
own  in the aggregate more than 3  percent of the total outstanding voting stock
of the investment company or  (b) such a purchase would  cause the Fund to  have
more  than 5 percent of  its total assets invested  in the investment company or
more than 10 percent of  its total assets invested in  an aggregate of all  such
investment  companies. Investment in such  investment companies may also involve
the payment of substantial premiums above the value of such companies' portfolio
securities. The  Funds do  not intend  to invest  in such  investment  companies
unless,  in  the judgment  of the  Sub-adviser, the  potential benefits  of such
investments justify the payment of any  applicable premiums. The return on  such
securities  will be  reduced by operating  expenses of  such companies including
payments to the investment managers of those investment companies. With  respect
to  investments in Affiliated Funds, the  Sub-adviser waives its advisory fee to
the extent that such fees are based on assets of the Fund invested in Affiliated
Funds.
 
Certain countries  in which  the Funds  invest  presently may  be made  only  by
acquiring  shares of other investment companies with local governmental approval
to invest  in  those countries.  At  such time  as  direct investment  in  those
countries is allowed, the Funds anticipate investing directly in those markets.

                         AIM LATIN AMERICAN GROWTH FUND
 
   
DEPOSITARY RECEIPTS
    
   
Each  Fund may hold equity securities of foreign issuers in the form of American
Depositary  Receipts  ("ADRs"),  American  Depositary  Shares  ("ADSs"),  Global
Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs"), or other
securities convertible into securities of eligible issuers. These securities may
not  necessarily be denominated in the same currency as the securities for which
they may be exchanged. ADRs and ADSs typically are issued by an American bank or
trust company  and  evidence ownership  of  underlying securities  issued  by  a
foreign  corporation.  EDRs,  which  are sometimes  referred  to  as Continental
Depositary Receipts ("CDRs"), are  issued in Europe  typically by foreign  banks
and  trust  companies  and  evidence ownership  of  either  foreign  or domestic
securities. GDRs  are  similar to  EDRs  and are  designed  for use  in  several
international financial markets. Generally, ADRs and ADSs in registered form are
designed for use in United States securities markets and EDRs in bearer form are
designed  for use  in European securities  markets. For purposes  of each Fund's
investment policies, a Fund's investments in  ADRs, ADSs, GDRs and EDRs will  be
deemed  to be  investments in the  equity securities  representing securities of
foreign issuers into which they may be converted.
    
 
ADR facilities may be established as either "unsponsored" or "sponsored."  While
ADRs  issued under these two  types of facilities are  in some respects similar,
there are distinctions between  them relating to the  rights and obligations  of
ADR holders and the practices of market participants. A depository may establish
an  unsponsored  facility  without  participation by  (or  even  necessarily the
acquiescence of) the issuer of the deposited securities, although typically  the
depository  requests a  letter of  non-objection from  such issuer  prior to the
establishment of the facility.  Holders of unsponsored  ADRs generally bear  all
the  costs  of such  facilities. The  depository usually  charges fees  upon the
deposit and withdrawal of the deposited securities, the conversion of  dividends
into   U.S.  dollars,  the  disposition   of  non-cash  distributions,  and  the
performance of  other  services.  The  depository  of  an  unsponsored  facility
frequently  is  under  no obligation  to  distribute  shareholder communications
received from the issuer of the  deposited securities or to pass-through  voting
rights  to ADR  holders in  respect of  the deposited  securities. Sponsored ADR
facilities are created in generally  the same manner as unsponsored  facilities,
except  that  the  issuer of  the  deposited  securities enters  into  a deposit
agreement with the  depository. The deposit  agreement sets out  the rights  and
responsibilities  of  the  issuer,  the depository  and  the  ADR  holders. With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository), although ADR holders continue to bear certain other costs (such  as
deposit  and withdrawal fees).  Under the terms  of most sponsored arrangements,
depositories agree  to distribute  notices of  shareholder meetings  and  voting
instructions, and to provide shareholder communications and other information to
the  ADR holders at the  request of the issuer  of the deposited securities. The
Fund may invest in both sponsored and unsponsored ADRs.
 
WARRANTS OR RIGHTS
Warrants or  rights  may be  acquired  by each  Fund  in connection  with  other
securities  or separately  and provide a  Fund with  the right to  purchase at a
later date other securities of  the issuer. Warrants are securities  permitting,
but   not  obligating,  their  holder  to  subscribe  for  other  securities  or
commodities. Warrants do not  carry with them the  right to dividends or  voting
rights  with  respect  to  the  securities that  they  entitle  their  holder to
purchase, and they do not represent any rights in the assets of the issuer. As a
result, warrants may be considered more speculative than certain other types  of
investments.  In addition,  the value of  a warrant does  not necessarily change
with the value of the underlying securities  and a warrant ceases to have  value
if it is not exercised prior to its expiration date.
 
LENDING OF PORTFOLIO SECURITIES
For the purpose of realizing additional income, the Funds may make secured loans
of  portfolio  securities  amounting  to  not more  than  30%  (in  the  case of
Developing Markets Fund and Emerging Markets Fund) or 25% (in the case of  Latin
American  Fund) of its total assets. Securities loans are made to broker/dealers
or institutional  investors  pursuant to  agreements  requiring that  the  loans
continuously  be secured by collateral at least  equal at all times to the value
of the securities lent plus any accrued interest, "marked to market" on a  daily
basis.  The  Funds  may  pay reasonable  administrative  and  custodial  fees in
connection  with  loans  of  its  securities.  While  the  securities  loan   is
outstanding  with  respect to  a Fund,  the  Fund will  continue to  receive the
equivalent of the interest or dividends paid by the issuer on the securities, as
well as interest on the investment of the collateral or a fee from the borrower.
The Fund will have a  right to call each loan  and obtain the securities  within
the  stated settlement period. The  Fund will not have  the right to vote equity
securities while they are lent, but it may call in a loan in anticipation of any
important vote. Loans will be made only to firms deemed by the Sub-adviser to be
of good  standing  and  will  not  be  made  unless,  in  the  judgment  of  the
Sub-adviser,  the consideration to  be earned from such  loans would justify the
risk.

                         AIM LATIN AMERICAN GROWTH FUND
 
COMMERCIAL BANK OBLIGATIONS
For the  purposes  of each  Fund's  investment  policies with  respect  to  bank
obligations,  obligations of foreign branches of U.S. banks and of foreign banks
are obligations of the issuing bank and may be general obligations of the parent
bank. Such  obligations, however,  may be  limited by  the terms  of a  specific
obligation  and  by  government  regulation.  As  with  investment  in  non-U.S.
securities in general,  investments in  the obligations of  foreign branches  of
U.S.  banks and of foreign banks may subject a Fund to investment risks that are
different in some respects from those of investments in obligations of  domestic
issuers. Although a Fund typically will acquire obligations issued and supported
by  the credit  of U.S.  or foreign  banks having  total assets  at the  time of
purchase in excess of $1  billion, this $1 billion  figure is not an  investment
policy  or restriction of any Fund. For the purposes of calculation with respect
to the $1 billion  figure, the assets of  a bank will be  deemed to include  the
assets of its U.S. and non-U.S. branches.
 
REPURCHASE AGREEMENTS
   
A  repurchase agreement is  a transaction in  which a Fund  purchases a security
from a bank or recognized securities dealer and simultaneously commits to resell
that security to the bank  or dealer at an agreed  upon price, date, and  market
rate  of interest  unrelated to  the coupon  rate or  maturity of  the purchased
security. Although repurchase agreements carry certain risks not associated with
direct investments in securities, including possible decline in the market value
of the underlying securities and delays and  costs to a Fund if the other  party
to  the repurchase  agreement becomes bankrupt,  the Funds intend  to enter into
repurchase agreements only with banks and dealers believed by the Sub-adviser to
present minimum credit risks  in accordance with  guidelines established by  the
Trust's  Board  of  Trustees.  The  Sub-adviser  will  review  and  monitor  the
creditworthiness of such institutions under the Board's general supervision.
    
 
   
The Funds will invest only in repurchase agreements collateralized at all  times
in  an amount at least  equal to the repurchase  price plus accrued interest. To
the extent that the proceeds from any sale of such collateral upon a default  in
the  obligation to repurchase were less than  the repurchase price, a Fund would
suffer a loss.  If the financial  institution which is  party to the  repurchase
agreement petitions for bankruptcy or otherwise becomes subject to bankruptcy or
other  liquidation proceedings, there may be restrictions on a Fund's ability to
sell the collateral and the Fund could  suffer a loss. However, with respect  to
financial  institutions whose bankruptcy or  liquidation proceedings are subject
to the U.S. Bankruptcy Code, each  Fund intends to comply with provisions  under
the  U.S.  Bankruptcy  Code  that  would  allow  it  immediately  to  resell the
collateral. There is no limitation on the amount of a Fund's assets that may  be
subject  to repurchase agreements  at any given  time. The Funds  will not enter
into a repurchase agreement  with a maturity  of more than seven  days if, as  a
result, more than 15% (for Emerging Markets Fund and Developing Markets Fund) or
10%  (for Latin American Fund) of the value  of its net assets would be invested
in such repurchase agreements and other illiquid investments.
    
 
   
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
    
   
No Fund's borrowings will exceed 33 1/3% of the Fund's total assets, i.e.,  each
Fund's  total assets  at all  times will equal  at least  300% of  the amount of
outstanding borrowings.  If  market  fluctuations  in  the  value  of  a  Fund's
portfolio  holdings or other factors cause the  ratio of the Fund's total assets
to outstanding  borrowings to  fall  below 300%,  within three  days  (excluding
Sundays  and holidays) of such event the  Fund may be required to sell portfolio
securities to restore the  300% asset coverage, even  though from an  investment
standpoint  such sales might be disadvantageous. Each Fund also may borrow up to
5% of its total assets  for temporary or emergency  purposes other than to  meet
redemptions.  Any borrowing by a Fund may cause greater fluctuation in the value
of its shares than would be the case if the Fund did not borrow.
    
 
   
The Funds' fundamental investment  limitations permit them  to borrow money  for
leveraging  purposes. Developing Markets Fund, however, currently is prohibited,
pursuant to a non-fundamental investment  policy, from borrowing money in  order
to  purchase securities. In  addition, Emerging Markets  Fund and Latin American
Fund currently are prohibited, pursuant to a non-fundamental investment  policy,
from  purchasing securities  during times when  outstanding borrowings represent
more than 5%  of its assets.  Nevertheless, this  policy may be  changed in  the
future  by a  vote of a  majority of  the Trust's Board  of Trustees.  If a Fund
employs leverage in the future, it would be subject to certain additional risks.
Use of leverage creates an opportunity  for greater growth of capital but  would
exaggerate  any increases or decreases  in the Fund's net  asset value. When the
income and gains on securities purchased with the proceeds of borrowings  exceed
the  costs  of such  borrowings, the  Fund's  earnings or  net asset  value will
increase faster than otherwise would be the case; conversely, if such income and
gains fail to exceed such  costs, the Fund's earnings  or net asset value  would
decline faster than would otherwise be the case.

Each  Fund may  enter into reverse  repurchase agreements.  A reverse repurchase
agreement is a borrowing transaction in  which a Fund transfers possession of  a
security  to another party, such as a  bank or broker/dealer in return for cash,
and agrees to repurchase  the security in  the future at  an agreed upon  price,
which  includes an interest component. Emerging  Markets Fund also may engage in
"roll" borrowing  transactions  which  involve the  Fund's  sale  of  Government
National  Mortgage Association certificates or  other securities together with a
commitment (for which the Fund may receive  a fee) to purchase similar, but  not
identical,  securities  at  a  future  date. Each  Fund  will  segregate  with a
custodian, cash  or liquid  securities  in an  amount  sufficient to  cover  its
obligations  under "roll" transactions  (for Emerging Markets  Fund) and reverse
repurchase agreements  with  broker/dealers.  No  segregation  is  required  for
reverse repurchase agreements with banks.
    
 
SHORT SALES
The  Fund  may  make short  sales  of  securities, although  it  has  no current
intention of doing so. A short sale is  a transaction in which the Fund sells  a
security  in anticipation that  the market price of  that security will decline.
The Fund may  make short  sales (i)  as a form  of hedging  to offset  potential
declines  in long positions in securities it owns, or anticipates acquiring, and
(ii) in order to maintain portfolio flexibility.
 
When a Fund makes a short sale of a security it does not own, it must borrow the
security sold short and  deliver it to the  broker-dealer or other  intermediary
through  which it made the short sale. The Fund  may have to pay a fee to borrow
particular securities  and will  often be  obligated to  pay over  any  payments
received on such borrowed securities.
 
A  Fund's  obligation to  replace the  borrowed security  when the  borrowing is
called or expires will be secured by collateral deposited with the intermediary.
The Fund will also be required to  deposit collateral with its custodian to  the
extent,  if any, necessary so that the  value of both collateral deposits in the
aggregate is at all times equal to at least 100% of the current market value  of
the  security sold short.  Depending on arrangements  made with the intermediary
from which it borrowed the security regarding payment of any amounts received by
the Fund on  such security,  the Fund may  not receive  any payments  (including
interest) on its collateral deposited with such intermediary.
 
If  the price of the security sold short increases between the time of the short
sale and the time the Fund replaces the borrowed security, the Fund will incur a
loss; conversely, if the price declines, the Fund will realize a gain. Any  gain
will  be decreased, and any loss  increased, by the transaction costs associated
with the transaction. Although the Fund's gain is limited by the price at  which
it sold the security short, its potential loss is theoretically unlimited.
 
Neither Emerging Markets Fund nor Latin American Fund will make a short sale if,
after  giving effect to such sale, the market value of the securities sold short
exceeds 25% of the value of its total assets or the Fund's aggregate short sales
of the securities of any  one issuer exceed the lesser  of 2% of the Fund's  net
assets or 2% of the securities of any class of the issuer. Moreover, these Funds
may  engage in short sales only with  respect to securities listed on a national
securities exchange. These Funds may make short sales "against the box"  without
respect to such limitations. In this type of short sale, at the time of the sale
the  Fund  owns  the  security  it  has sold  short  or  has  the  immediate and
unconditional right to acquire at no additional cost the identical security.
 
Developing Markets Fund may  only make short sales  "against the box." The  Fund
might make a short sale "against the box" in order to hedge against market risks
when  the Sub-adviser believes that the price of a security may decline, causing
a decline in the value of a security owned by the Fund or a security convertible
into or exchangeable for such security. In  such case, any future losses in  the
Fund's  long  position  should be  reduced  by  a gain  in  the  short position.
Conversely, any gain in  the long position  should be reduced by  a loss in  the
short  position. The extent to  which such gains or  losses in the long position
are reduced will depend upon the amount of the securities sold short relative to
the amount of the securities the Fund owns, either directly or indirectly,  and,
in  the  case  where  the  Fund  owns  convertible  securities,  changes  in the
investment values  or conversion  premiums  of such  securities. There  will  be
certain  additional transaction costs  associated with short  sales "against the
box," but the  Fund will endeavor  to offset  these costs with  income from  the
investment of the cash proceeds of short sales.
 
TEMPORARY DEFENSIVE STRATEGIES
The  Funds may invest in the following  types of money market instruments (i.e.,
debt instruments with less than 12 months remaining until maturity)  denominated
in  U.S. dollars or  other currencies (in  the case of  Latin American Fund, the
currency of any Latin American country): (a) obligations issued or guaranteed by
the U.S.  or  foreign governments  (in  the case  of  Latin American  Fund,  the
government  of any Latin American country), their agencies, instrumentalities or
municipalities; (b)  obligations  of  international  organizations  designed  or
supported by multiple foreign governmental

entities  to promote economic reconstruction or development; (c) finance company
obligations,  corporate  commercial  paper   and  other  short-term   commercial
obligations;  (d)  bank  obligations (including  certificates  of  deposit, time
deposits, demand deposits and  bankers' acceptances); (e) repurchase  agreements
with  respect to the  foregoing; and (f)  other substantially similar short-term
debt securities with comparable characteristics.
 
The Funds may  invest in  commercial paper  rated as low  as A-3  by Standard  &
Poor's,  a division of The McGraw-Hill Companies, Inc. ("S&P") or P-3 by Moody's
Investors Service, Inc. ("Moody's") or, if not rated, determined by the  Manager
to be of comparable quality. Obligations rated A-3 and P-3 are considered by S&P
and  Moody's, respectively, to have an acceptable capacity for timely repayment.
However, these securities may be more  vulnerable to adverse effects of  changes
in circumstances than obligations carrying higher designations.
 
SAMURAI AND YANKEE BONDS
Subject  to its fundamental investment restrictions, Developing Markets Fund and
Emerging Markets  Fund may  invest in  yen-denominated bonds  sold in  Japan  by
non-Japanese  issuers ("Samurai  bonds"), and  may invest  in dollar-denominated
bonds sold  in  the United  States  by  non-U.S. issuers  ("Yankee  bonds").  As
compared  with bonds  issued in  their countries  of domicile,  such bond issues
normally carry a higher interest  rate but are less  actively traded. It is  the
policy  of each of these  Funds to invest in Samurai  or Yankee bond issues only
after taking into account  considerations of quality and  liquidity, as well  as
yield.  In the  case of Emerging  Markets Fund,  these bonds would  be issued by
governments which are members of  the Organization for Economic Cooperation  and
Development or have AAA ratings.
 
DEBT CONVERSIONS
Several Latin American countries have adopted debt conversion programs, pursuant
to  which investors may use external debt  of a country, directly or indirectly,
to make investments in local companies.  The terms of the various programs  vary
from country to country, although each program includes significant restrictions
on  the  application of  the  proceeds received  in  the conversion  and  on the
remittance of  profits on  the investment  and of  the invested  capital.  Latin
American  Fund intends to acquire Sovereign  Debt, as defined in the Prospectus,
to hold and trade in appropriate  circumstances as described in the  Prospectus,
as  well  as to  participate  in Latin  American  debt conversion  programs. The
Sub-adviser  will  evaluate   opportunities  to  enter   into  debt   conversion
transactions  as they arise but does not currently intend to invest more than 5%
of the Fund's assets in such programs.
 
PREMIUM SECURITIES
Developing Markets Fund  may invest  in income securities  bearing coupon  rates
higher  than prevailing  market rates.  Such "premium"  securities are typically
purchased at prices greater than the principal amounts payable on maturity.  The
Fund  will not amortize the premium paid  for such securities in calculating its
net investment  income.  As  a  result,  in such  cases  the  purchase  of  such
securities  provides the Fund a higher  level of investment income distributable
to shareholders on a current basis than if the Fund purchased securities bearing
current market  rates of  interest. If  securities purchased  by the  Fund at  a
premium  are called or sold  prior to maturity, the Fund  will realize a loss to
the extent the call or sale price is less than the purchase price. Additionally,
the Fund will realize a loss if it holds such securities to maturity.
 
INDEXED DEBT SECURITIES
Developing Markets Fund may invest in debt securities issued by banks and  other
business entities not located in developing market countries that are indexed to
certain  specific  foreign  currency  exchange rates,  interest  rates  or other
reference rates.  The terms  of  such securities  provide that  their  principal
amount  is  adjusted upwards  or downwards  (but ordinarily  not below  zero) at
maturity to reflect  changes in  the exchange  rate between  two currencies  (or
other  rates) while the obligations are outstanding. While such securities offer
the potential for an  attractive rate of  return, they also  entail the risk  of
loss  of principal. New forms  of such securities continue  to be developed. The
Fund may invest in such securities to the extent consistent with its  investment
objectives.
 
STRUCTURED INVESTMENTS
Developing  Markets Fund  may invest  a portion  of its  assets in  interests in
entities organized  and operated  solely for  the purpose  of restructuring  the
investment  characteristics  of  Sovereign  Debt.  This  type  of  restructuring
involves the deposit with  or purchase by  an entity, such  as a corporation  or
trust,  of specified instruments (such as  commercial bank loans or Brady Bonds)
and  the  issuance  by  that  entity  of  one  or  more  classes  of  securities
("Structured   Investments")  backed  by,  or  representing  interests  in,  the
underlying instruments.  The cash  flow  on the  underlying instruments  may  be
apportioned  among the newly issued  Structured Investments to create securities
with different investment  characteristics such as  varying maturities,  payment
priorities  and interest  rate provisions, and  the extent of  the payments made
with respect to Structured  Investments is dependent on  the extent of the  cash
flow on the underlying instruments. Because Structured

                         AIM LATIN AMERICAN GROWTH FUND
Investments  of the type in which the  Fund anticipates it will invest typically
involve no credit enhancement, their credit risk generally will be equivalent to
that of the underlying instruments.
 
Developing Markets  Fund  is  permitted  to invest  in  a  class  of  Structured
Investments  that is  either subordinated  or not  subordinated to  the right of
payment of  another class.  Subordinated Structured  Investments typically  have
higher   yields  and  present  greater   risks  than  unsubordinated  Structured
Investments.
 
Certain issuers  of  Structured Investments  may  be deemed  to  be  "investment
companies"  as defined in the  1940 Act. As a  result, Developing Markets Fund's
investment in these Structured  Investments may be  limited by the  restrictions
contained  in  the 1940  Act described  above  under "Investment  Objectives and
Policies -- Investments in  Other Investment Companies." Structured  Investments
are  typically sold in private placement transactions, and there currently is no
active trading market for Structured Investments.
 
STRIPPED INCOME SECURITIES
Developing Markets Fund may  invest a portion of  its assets in stripped  income
securities,  which are obligations representing an  interest in all or a portion
of the income or  principal components of an  underlying or related security,  a
pool  of securities or  other assets. In  the most extreme  case, one class will
receive all of the interest (the interest  only or "IO" class), while the  other
class  will receive all of the principal (the principal-only or "PO" class). The
market values of stripped income securities tend to be more volatile in response
to changes in interest rates than are conventional income securities.
 
FLOATING AND VARIABLE RATE INCOME SECURITIES
Developing Markets  Fund may  invest a  portion  of its  assets in  floating  or
variable  rate income securities. Income securities  may provide for floating or
variable rate interest or dividend payments.  The floating or variable rate  may
be determined by reference to a known lending rate, such as a bank's prime rate,
a  certificate of deposit  rate or the  London Inter Bank  Offered Rate (LIBOR).
Alternatively, the  rate may  be determined  through an  auction or  remarketing
process.  The rate also may be indexed to changes in the values of interest rate
or securities indexes, currency exchange rates or other commodities. The  amount
by  which the rate  paid on an income  security may increase  or decrease may be
subject to  periodic  or  lifetime  caps.  Floating  and  variable  rate  income
securities  include securities whose rates vary inversely with changes in market
rates of interest. Such securities may also pay a rate of interest determined by
applying a multiple to the variable rate. The extent of increases and  decreases
in  the value of  securities whose rates  vary inversely with  changes in market
rates of interest generally will be larger than comparable changes in the  value
of  an equal  principal amount  of a fixed  rate security  having similar credit
quality, redemption provisions and maturity.
 
SWAPS, CAPS, FLOORS AND COLLARS
Developing Markets Fund may enter into  interest rate, currency and index  swaps
and  may purchase or sell related caps,  floors and collars and other derivative
instruments. The  Fund expects  to enter  into these  transactions primarily  to
preserve  a  return or  spread  on a  particular  investment or  portion  of its
portfolio, to protect against currency fluctuations, as a technique for managing
the portfolio's duration  (I.E., the  price sensitivity to  changes in  interest
rates)  or to protect against  any increase in the  price of securities the Fund
anticipates  purchasing  at  a  later  date.  The  Fund  intends  to  use  these
transactions  as hedges and will not sell  interest rate caps, floors or collars
if it does not  own securities or other  instruments providing an income  stream
roughly equivalent to what the Fund may be obligated to pay.
 
Interest rate swaps involve the exchange by Developing Markets Fund with another
party  of their respective commitments to  pay or receive interest (for example,
an exchange of floating rate payments for fixed rate payments) with respect to a
notional amount of principal. A currency  swap is an agreement to exchange  cash
flows  on a  notional amount  based on  changes in  the values  of the reference
indices.
 
The purchase of a cap entitles the  purchaser to receive payments on a  notional
principal  amount from the party selling the  cap to the extent that a specified
index exceeds a predetermined  interest rate. The purchase  of an interest  rate
floor  entitles the purchaser to receive payments on a notional principal amount
from the party  selling the floor  to the  extent that a  specified index  falls
below  a predetermined interest rate  or amount. A collar  is a combination of a
cap and a floor that preserves a certain return within a predetermined range  of
interest rates or values.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use of options, futures contracts  and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1) Successful  use  of  most  of these  instruments  depends  upon  the
    Sub-adviser's  ability to  predict movements  of the  overall securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-adviser is experienced in
    the use of these instruments, there can be no assurance that any  particular
    strategy adopted will succeed.
 
        (2)  There  might  be  imperfect correlation,  or  even  no correlation,
    between price  movements  of  an  instrument  and  price  movements  of  the
    investments being hedged. For example, if the value of an instrument used in
    a  short hedge  increased by less  than the  decline in value  of the hedged
    investment, the  hedge  would  not  be fully  successful.  Such  a  lack  of
    correlation  might  occur  due to  factors  unrelated  to the  value  of the
    investments being  hedged, such  as speculative  or other  pressures on  the
    markets  in which  the hedging  instrument is  traded. The  effectiveness of
    hedges using hedging  instruments on indices  will depend on  the degree  of
    correlation  between price movements in the index and price movements in the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative  effect of unfavorable price  movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity  for gain by  offsetting the positive  effect of favorable price
    movements in the hedged investments. For  example, if a Fund entered into  a
    short  hedge because the Sub-adviser  projected a decline in  the price of a
    security in the Fund's portfolio, and  the price of that security  increased
    instead,  the gain from that increase might by wholly or partially offset by
    a decline in the price of the hedging instrument. Moreover, if the price  of
    the  hedging instrument declined by  more than the increase  in the price of
    the security, the Fund could  suffer a loss. In  either such case, the  Fund
    would have been in a better position had it not hedged at all.
 
        (4)  As described below, a Fund might  be required to maintain assets as
    "cover," maintain segregated accounts or make margin payments when it  takes
    positions  in  instruments  involving obligations  to  third  parties (i.e.,
    instruments other than purchased options). If the Fund were unable to  close
    out  its positions in such instruments, it  might be required to continue to
    maintain such assets or  accounts or make such  payments until the  position
    expired or matured. The requirements might impair the Fund's ability to sell
    a portfolio security or make an investment at a time when it would otherwise
    be favorable to do so, or require that the Fund sell a portfolio security at
    a  disadvantageous time.  A Fund's  ability to  close out  a position  in an
    instrument prior to  expiration or maturity  depends on the  existence of  a
    liquid secondary market or, in the absence of such a market, the ability and
    willingness  of the other party to the transaction ("contra party") to enter
    into a  transaction  closing  out  the  position.  Therefore,  there  is  no
    assurance  that any position can  be closed out at a  time and price that is
    favorable to the Funds.
 
WRITING CALL OPTIONS
Each Fund may write (sell) call  options on securities, indices and  currencies.
Call options generally will be written on securities and currencies that, in the
opinion of the Sub-adviser are not expected to make any major price moves in the
near  future  but  that,  over  the  long  term,  are  deemed  to  be attractive
investments for a Fund.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
Style) or on (European Style) a certain  date (the expiration date). So long  as
the  obligation of the writer of a call  option continues, he may be assigned an
exercise notice, requiring him  to deliver the  underlying security or  currency
against  payment  of the  exercise price.  This  obligation terminates  upon the
expiration of the call option, or such earlier time at which the writer  effects
a  closing  purchase  transaction  by purchasing  an  option  identical  to that
previously sold.

                         AIM LATIN AMERICAN GROWTH FUND
 
Portfolio securities or currencies on which call options may be written will  be
purchased  solely on the basis of investment considerations consistent with each
Fund's investment objective. When writing a  call option, a Fund, in return  for
the  premium, gives up the  opportunity for profit from  a price increase in the
underlying security or currency above the  exercise price, and retains the  risk
of  loss should the  price of the  security or currency  decline. Unlike one who
owns securities or currencies not  subject to an option,  a Fund has no  control
over  when it may be  required to sell the  underlying securities or currencies,
since most  options  may  be  exercised  at  any  time  prior  to  the  option's
expiration.  If a  call option that  a Fund  has written expires,  the Fund will
realize a gain in the amount of the premium; however, such gain may be offset by
a decline in the market value of the underlying security or currency during  the
option  period. If the call option is exercised, the Fund will realize a gain or
loss from  the  sale of  the  underlying security  or  currency, which  will  be
increased  or  offset by  the  premium received.  The  Funds do  not  consider a
security or currency covered by  a call option to be  "pledged" as that term  is
used  in the  Funds' policies  that limit  the pledging  or mortgaging  of their
assets.
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option  will be exercised and a  Fund will be obligated to
sell the security or currency at less than its market value.
 
The premium  that  a Fund  receives  for writing  a  call option  is  deemed  to
constitute  the market value of an option.  The premium a Fund will receive from
writing a call option will reflect, among other things, the current market price
of the underlying  investment, the relationship  of the exercise  price to  such
market  price, the historical price volatility of the underlying investment, and
the length of the option period. In determining whether a particular call option
should be  written, the  Sub-adviser  will consider  the reasonableness  of  the
anticipated premium and the likelihood that a liquid secondary market will exist
for those options.
 
Closing  transactions  will be  effected  in order  to  realize a  profit  on an
outstanding call  option, to  prevent an  underlying security  or currency  from
being  called, or  to permit  the sale of  the underlying  security or currency.
Furthermore, effecting a closing transaction will permit a Fund to write another
call option  on the  underlying security  or currency  with either  a  different
exercise price, expiration date or both.
 
Each  Fund will pay transaction costs in  connection with the writing of options
and in entering into closing  purchase contracts. Transaction costs relating  to
options  activity normally  are higher  than those  applicable to  purchases and
sales of portfolio securities.
 
The exercise price of the  options may be below, equal  to or above the  current
market values of the underlying securities or currencies at the time the options
are  written. From time to  time, a Fund may  purchase an underlying security or
currency for delivery in accordance with the exercise of an option, rather  than
delivering  such  security  or  currency  from  its  portfolio.  In  such cases,
additional costs will be incurred.
 
A Fund will realize a profit or loss from a closing purchase transaction if  the
cost of the transaction is less or more, respectively, than the premium received
from  writing the option. Because increases in the market price of a call option
generally will reflect increases in the market price of the underlying  security
or  currency, any loss resulting from the  repurchase of a call option is likely
to be offset in whole or in  part by appreciation of the underlying security  or
currency owned by the Fund.
 
WRITING PUT OPTIONS
Each  Fund may write  put options on  securities, indices and  currencies. A put
option gives the  purchaser of  the option  the right  to sell,  and the  writer
(seller)  the  obligation to  buy, the  underlying security  or currency  at the
exercise price at  any time until  (American style) or  on (European style)  the
expiration date. The operation of put options in other respects, including their
related risks and rewards, is identical substantially to that of call options.
 
   
A  Fund generally would write put options in circumstances where the Sub-adviser
wishes to purchase the underlying security or currency for the Fund's  portfolio
at  a price lower than the current market  price of the security or currency. In
such event, the Fund would write a put option at an exercise price that, reduced
by the premium received on the option, reflects the lower price it is willing to
pay. Since the Fund would also receive interest on debt securities or currencies
maintained to cover the  exercise price of the  option, this technique could  be
used to enhance current return during periods of market uncertainty. The risk in
such  a transaction would be that the market price of the underlying security or
currency would decline below the exercise price less the premium received.

                         AIM LATIN AMERICAN GROWTH FUND
 
Writing put options can serve as a  limited long hedge because increases in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
depreciates  to a price lower than the exercise  price of the put option, it can
be expected that the put option will be exercised and the Fund will be obligated
to sell the security or currency at more than its market value.
 
PURCHASING PUT OPTIONS
Each Fund may purchase put options on securities, indices and currencies. As the
holder of a  put option,  a Fund  would have the  right to  sell the  underlying
security or currency at the exercise price at any time until (American style) or
on  (European style)  the expiration  date. A Fund  may enter  into closing sale
transactions with  respect to  such options,  exercise them  or permit  them  to
expire.
 
A  Fund  may  purchase  a  put option  on  an  underlying  security  or currency
("protective put") owned by the Fund  to protect against an anticipated  decline
in  the value  of the  security or  currency. Such  protection is  provided only
during the life  of the  put option  when the  Fund, as  the holder  of the  put
option,  is able to sell the underlying security or currency at the put exercise
price regardless of  any decline in  the underlying security's  market price  or
currency's  exchange  value.  The  premium  paid  for  the  put  option  and any
transaction costs would reduce any  profit otherwise available for  distribution
when the security or currency is eventually sold.
 
A  Fund also may purchase put  options at a time when  the Fund does not own the
underlying security or  currency. By  purchasing put  options on  a security  or
currency it does not own, the Fund seeks to benefit from a decline in the market
price of the underlying security or currency. If the put option is not sold when
it  has remaining value, and  if the market price  of the underlying security or
currency remains equal to or greater than the exercise price during the life  of
the  put option, the Fund will lose its  entire investment in the put option. In
order for the purchase of a put option to be profitable, the market price of the
underlying security or  currency must  decline sufficiently  below the  exercise
price  to cover the premium and transaction costs, unless the put option is sold
in a closing sale transaction.
 
PURCHASING CALL OPTIONS
Each Fund may purchase  call options on securities,  indices and currencies.  As
the  holder  of a  call option,  a Fund  would  have the  right to  purchase the
underlying security  or  currency  at  the exercise  price  at  any  time  until
(American  style) or on (European  style) the expiration date.  A Fund may enter
into closing sale transactions  with respect to such  options, exercise them  or
permit them to expire.
 
   
Call  options  may be  purchased  by a  Fund for  the  purpose of  acquiring the
underlying security or currency for its portfolio. Utilized in this fashion, the
purchase of  call options  would enable  the  Fund to  acquire the  security  or
currency  at the  exercise price of  the call  option plus the  premium paid. At
times, the net cost of acquiring the security or currency in this manner may  be
less  than  the  cost  of  acquiring the  security  or  currency  directly. This
technique also may be useful to a Fund in purchasing a large block of securities
that would be more difficult to acquire  by direct market purchases. So long  as
it  holds such a  call option, rather  than the underlying  security or currency
itself, the  Fund is  partially protected  from any  unexpected decline  in  the
market  price of the underlying  security or currency and,  in such event, could
allow the call  option to expire,  incurring a loss  only to the  extent of  the
premium paid for the option.
    
 
A  Fund also may purchase call options on underlying securities or currencies it
owns to avoid realizing losses that would  result in a reduction of its  current
return.  For example, where  a Fund has  written a call  option on an underlying
security or currency having a current market  value below the price at which  it
purchased the security or currency, an increase in the market price could result
in  the exercise of the call option written by the Fund and the realization of a
loss on  the  underlying  security  or currency.  Accordingly,  the  Fund  could
purchase  a call option on the same underlying security or currency, which could
be exercised to fulfill the Fund's  delivery obligations under its written  call
(if  it is exercised). This  strategy could allow the  Fund to avoid selling the
portfolio security  or  currency at  a  time when  it  has an  unrealized  loss;
however,  the Fund would have to pay a  premium to purchase the call option plus
transaction costs.
 
Aggregate premiums paid for put and call options will not exceed 5% of a  Fund's
total assets at the time of purchase.
 
Each  Fund may attempt to accomplish objectives similar to those involved in its
use of Forward Contracts by purchasing put or call options on currencies. A  put
option  gives a Fund as  purchaser the right (but not  the obligation) to sell a
specified amount of currency at the  exercise price at any time until  (American
style) or on (European style) the expiration date. A call option gives a Fund as
purchaser  the right (but not the obligation)  to purchase a specified amount of
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style)  the expiration  date. A  Fund might  purchase a  currency put
option, for example, to protect itself against a decline in the dollar value  of
a currency in which it holds or

                         AIM LATIN AMERICAN GROWTH FUND
anticipates  holding securities. If the  currency's value should decline against
the dollar, the loss in currency value should be offset, in whole or in part, by
an increase in the value of the put. If the value of the currency instead should
rise against the dollar, any gain to the Fund would be reduced by the premium it
had paid for  the put option.  A currency  call option might  be purchased,  for
example,  in anticipation of, or to protect against, a rise in the value against
the dollar of a currency in which a Fund anticipates purchasing securities.
 
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing corporation), and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates.  A Fund  will not purchase  an OTC  option unless it  believes that daily
valuations for  such options  are readily  obtainable. OTC  options differ  from
exchange-traded options in that OTC options are transacted with dealers directly
and   not  through  a  clearing   corporation  (which  guarantees  performance).
Consequently, there  is  a risk  of  non-performance  by the  dealer.  Since  no
exchange  is involved, OTC options are valued on  the basis of an average of the
last bid prices obtained from dealers,  unless a quotation from only one  dealer
is  available, in which case only that dealer's  price will be used. In the case
of OTC options, there can  be no assurance that  a liquid secondary market  will
exist for any particular option at any specific time.
 
The  staff of the SEC considers purchased OTC options to be illiquid securities.
A Fund may also sell OTC options and, in connection therewith, segregate  assets
or  cover its obligations with  respect to OTC options  written by the Fund. The
assets used as  cover for OTC  options written  by the Fund  will be  considered
illiquid unless the OTC options are sold to qualified dealers who agree that the
Fund may repurchase any OTC option it writes at a maximum price to be calculated
by  a formula  set forth in  the option agreement.  The cover for  an OTC option
written subject  to this  procedure would  be considered  illiquid only  to  the
extent that the maximum repurchase price under the formula exceeds the intrinsic
value of the option.
 
A Fund's ability to establish and close out positions in exchange-listed options
depends  on the existence of  a liquid market. Each  Fund intends to purchase or
write only those exchange-traded options for which there appears to be a  liquid
secondary  market. However, there  can be no  assurance that such  a market will
exist at any particular time. Closing  transactions can be made for OTC  options
only  by negotiating directly with  the contra party or  by a transaction in the
secondary market if any such market  exists. Although each Fund will enter  into
OTC options only with contra parties that are expected to be capable of entering
into  closing transactions with the  Fund, there is no  assurance that the Funds
will in fact be able  to close out an OTC  option position at a favorable  price
prior  to expiration.  In the event  of insolvency  of the contra  party, a Fund
might be unable to  close out an OTC  option position at any  time prior to  its
expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts  except that all settlements  are in cash and  gain or loss depends on
changes in the index in question (and thus on price movements in the  securities
market  or a particular market sector  generally) rather than on price movements
in individual securities or futures contracts. When  a Fund writes a call on  an
index,  it receives a premium and agrees that, prior to the expiration date, the
purchaser of the call, upon exercise of the call, will receive from the Fund  an
amount of cash if the closing level of the index upon which the call is based is
greater  than the exercise price of the call. The amount of cash is equal to the
difference between the closing price of the index and the exercise price of  the
call  times a specified multiple (the  "multiplier"), which determines the total
dollar value for each point  of such difference. When a  Fund buys a call on  an
index,  it  pays a  premium and  has  the same  rights as  to  such call  as are
indicated above. When a Fund buys a put  on an index, it pays a premium and  has
the  right, prior to the expiration date, to require the seller of the put, upon
the Fund's exercise of the put, to deliver to the Fund an amount of cash if  the
closing level of the index upon which the put is based is less than the exercise
price  of the  put, which  amount of  cash is  determined by  the multiplier, as
described above for calls. When a Fund writes  a put on an index, it receives  a
premium  and  the purchaser  has the  right,  prior to  the expiration  date, to
require the Fund  to deliver to  it an amount  of cash equal  to the  difference
between  the  closing  level of  the  index  and the  exercise  price  times the
multiplier, if the closing level is less than the exercise price.
 
The risks  of  investment  in index  options  may  be greater  than  options  on
securities. Because index options are settled in cash, when a Fund writes a call
on  an  index  it  cannot  provide  in  advance  for  its  potential  settlement
obligations by  acquiring and  holding  the underlying  securities. A  Fund  can
offset  some of the  risk of writing a  call index option  position by holding a
diversified portfolio of  securities similar  to those on  which the  underlying
index is based. However, a Fund

<PAGE>
                          AIM DEVELOPING MARKETS FUND
                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
cannot,  as a practical matter, acquire  and hold a portfolio containing exactly
the same securities as underlie  the index and, as a  result, bears a risk  that
the value of the securities held will vary from the value of the index.
 
Even if a Fund could assemble a securities portfolio that exactly reproduced the
composition  of the underlying index, it still would not be fully covered from a
risk standpoint because of the "timing risk" inherent in writing index  options.
When  an  index option  is  exercised, the  amount of  cash  that the  holder is
entitled to receive is determined by  the difference between the exercise  price
and  the closing index level  on the date when the  option is exercised. As with
other kinds of options, a  Fund, as the call writer,  will not know that it  has
been  assigned until the next business day at the earliest. The time lag between
exercise and notice of assignment poses no risk for the writer of a covered call
on a  specific underlying  security, such  as common  stock, because  there  the
writer's  obligation is to deliver the underlying security, not to pay its value
as of  a  fixed time  in  the past.  So  long as  the  writer already  owns  the
underlying  security,  it  can  satisfy  its  settlement  obligations  by simply
delivering it, and the risk that its value may have declined since the  exercise
date  is borne by the  exercising holder. In contrast, even  if the writer of an
index call holds securities that exactly match the composition of the underlying
index, it will not be able  to satisfy its assignment obligations by  delivering
those  securities against  payment of  the exercise  price. Instead,  it will be
required to  pay cash  in an  amount based  on the  closing index  value on  the
exercise  date; and by the  time it learns that it  has been assigned, the index
may have declined, with a corresponding  decline in the value of its  securities
portfolio.  This "timing risk" is an inherent limitation on the ability of index
call writers to cover their risk exposure by holding securities positions.
 
If a Fund purchases an  index option and exercises  it before the closing  index
value  for  that day  is  available, it  runs  the risk  that  the level  of the
underlying index may subsequently change. If such a change causes the  exercised
option to fall out-of-the-money, the Fund will be required to pay the difference
between  the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.
 
   
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
    
Each Fund may enter  into interest rate or  currency futures contracts, and  may
enter  into stock index  futures contracts (collectively,  "Futures" or "Futures
Contracts"), as a hedge against changes in prevailing levels of interest  rates,
currency  exchange rates or  stock prices in order  to establish more definitely
the effective return on securities or currencies held or intended to be acquired
by the Fund. A  Fund's transactions may  include sales of  Futures as an  offset
against  the effect  of expected increases  in interest rates,  and decreases in
currency exchange rates and stock prices, and purchases of Futures as an  offset
against  the effect  of expected  declines in  interest rates,  and increases in
currency exchange rates and stock prices.
 
A Fund  will  only enter  into  Futures Contracts  that  are traded  on  futures
exchanges  and are  standardized as  to maturity  date and  underlying financial
instrument. Futures  exchanges and  trading  thereon in  the United  States  are
regulated  under the  Commodity Exchange  Act by  the Commodity  Futures Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used to reduce a  Fund's exposure to interest  rate, currency exchange rate  and
stock  market  fluctuations, a  Fund  may be  able  to hedge  its  exposure more
effectively and at a lower cost through using Futures Contracts.
 
A Futures Contract provides  for the future  sale by one  party and purchase  by
another party of a specified amount of a specific financial instrument (security
or  currency) for  a specified price  at a  designated date, time  and place. An
index Futures Contract provides for the delivery, at a designated date, time and
place, of  an amount  of  cash equal  to a  specified  dollar amount  times  the
difference  between the index value at the  close of trading on the contract and
the price  at which  the  Futures Contract  is  originally struck;  no  physical
delivery  of the  securities comprising  the index  is made.  Brokerage fees are
incurred when a Futures Contract is bought or sold, and margin deposits must  be
maintained at all times the Futures Contract is outstanding.
 
Although  Futures Contracts typically require future delivery of and payment for
financial instruments or  currencies, Futures Contracts  are usually closed  out
before  the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering  into an offsetting Futures  Contract purchase or  sale,
respectively,   for  the  same  aggregate  amount  of  the  identical  financial
instrument or currency and  the same delivery date.  If the offsetting  purchase
price  is less than  the original sale price,  a Fund realizes a  gain; if it is
more, a Fund realizes a loss. Conversely,  if the offsetting sale price is  more
than  the original purchase  price, a Fund realizes  a gain; if  it is less, the
Fund realizes  a loss.  The transaction  costs must  also be  included in  these
calculations.  There can be no  assurance, however, that a  Fund will be able to
enter into an offsetting

                         AIM LATIN AMERICAN GROWTH FUND
transaction with respect to a particular Futures Contract at a particular  time.
If  a Fund is  not able to enter  into an offsetting  transaction, the Fund will
continue to be required to maintain the margin deposits on the Futures Contract.
 
As an example of an offsetting transaction, the contractual obligations  arising
from  the sale of one Futures Contract of September Deutschemarks on an exchange
may be  fulfilled at  any time  before delivery  under the  Futures Contract  is
required  (I.E., on a specified date in  September, the "delivery month") by the
purchase of  another Futures  Contract of  September Deutschemarks  on the  same
exchange. In such instance the difference between the price at which the Futures
Contract  was  sold  and  the  price paid  for  the  offsetting  purchase, after
allowance for transaction costs, represents the profit or loss to the Fund.
 
Each Fund's Futures transactions will be entered into for hedging purposes only;
that is, Futures  Contracts will be  sold to  protect against a  decline in  the
price  of securities or currencies that the Fund owns, or Futures Contracts will
be purchased to protect the Fund against an increase in the price of  securities
or currencies it has committed to purchase or expects to purchase.
 
"Margin"  with respect to Futures Contracts is  the amount of funds that must be
deposited by a Fund  in order to  initiate Futures trading  and to maintain  the
Fund's  open  positions in  Futures Contracts.  A margin  deposit made  when the
Futures Contract is  entered into  ("initial margin")  is intended  to assure  a
Fund's  performance  under  the  Futures Contract.  The  margin  required  for a
particular Futures Contract is set by the exchange on which the Futures Contract
is traded and may be  modified significantly from time  to time by the  exchange
during the term of the Futures Contract.
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission merchant through which a Fund entered into the Futures Contract  will
be  made on a daily  basis as the price of  the underlying security, currency or
index fluctuates making the  Futures Contract more or  less valuable, a  process
known as marking-to-market.
 
    RISKS  OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts are
volatile and  are influenced  by,  among other  things, actual  and  anticipated
changes  in  interest rates  and currency  exchange rates,  and in  stock market
movements, which  in turn  are  affected by  fiscal  and monetary  policies  and
national and international political and economic events.
 
There  is a risk of  imperfect correlation between changes  in prices of Futures
Contracts and prices of the securities or currencies in a Fund's portfolio being
hedged. The degree  of imperfection  of correlation  depends upon  circumstances
such  as: variations in speculative market demand for Futures and for securities
or  currencies,  including   technical  influences  in   Futures  trading;   and
differences  between the financial instruments  being hedged and the instruments
underlying the standard Futures Contracts  available for trading. A decision  of
whether,  when,  and  how to  hedge  involves  skill and  judgment,  and  even a
well-conceived hedge may be  unsuccessful to some  degree because of  unexpected
market behavior or interest or currency rate trends.
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and options on Futures Contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a Futures  Contract
or option may vary either up or down from the previous day's settlement price at
the  end  of a  trading session.  Once the  daily  limit has  been reached  in a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a particular trading day and therefore does not limit potential losses,  because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and  option  prices  have occasionally  moved  to  the daily  limit  for several
consecutive trading days with  little or no  trading, thereby preventing  prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If  a Fund were unable to liquidate a  Futures or option on Futures position due
to the absence of a liquid secondary  market or the imposition of price  limits,
it  could incur  substantial losses.  The Fund would  continue to  be subject to
market risk with respect  to the position.  In addition, except  in the case  of
purchased    options,    the    Fund    would    continue    to    be   required

                         AIM LATIN AMERICAN GROWTH FUND
to make daily variation  margin payments and might  be required to maintain  the
position  being hedged by the Future or option or to maintain cash or securities
in a segregated account.
 
Certain characteristics  of the  Futures  market might  increase the  risk  that
movements  in the prices  of Futures Contracts  or options on  Futures might not
correlate perfectly  with  movements in  the  prices of  the  investments  being
hedged.  For example,  all participants  in the  Futures and  options on Futures
markets are subject to  daily variation margin calls  and might be compelled  to
liquidate  Futures  or  options on  Futures  positions whose  prices  are moving
unfavorably to avoid being  subject to further  calls. These liquidations  could
increase  price  volatility  of the  instruments  and distort  the  normal price
relationship between the Futures  or options and  the investments being  hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous  than  margin requirements  in the  securities  markets, there  might be
increased  participation   by  speculators   in   the  Futures   markets.   This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading"  and other  investment strategies  might result  in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options  on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the  premium paid,  to  assume a  position in  a  Futures Contract  (a  long
position if the option is a call and a short position if the option is a put) at
a  specified exercise price  at any time  during the period  of the option. Upon
exercise of the option, the  delivery of the Futures  position by the writer  of
the  option to the holder  of the option will be  accompanied by delivery of the
accumulated balance in the writer's Futures margin account, which represents the
amount by which the market price  of the Futures Contract, at exercise,  exceeds
(in  the case of  a call) or  is less than (in  the case of  a put) the exercise
price of the option on  the Futures Contract. If an  option is exercised on  the
last trading day prior to the expiration date of the option, the settlement will
be  made entirely in cash equal to  the difference between the exercise price of
the option and  the closing level  of the securities,  currencies or index  upon
which  the  Futures Contract  is  based on  the  expiration date.  Purchasers of
options who fail to exercise their options  prior to the exercise date suffer  a
loss of the premium paid.
 
The  purchase of  call options  on Futures can  serve as  a long  hedge, and the
purchase of put  options on Futures  can serve  as a short  hedge. Writing  call
options  on Futures can serve as a  limited short hedge, and writing put options
on Futures can serve as a limited  long hedge, using a strategy similar to  that
used for writing options on securities, foreign currencies or indices.
 
If a Fund writes an option on a Futures Contract, it will be required to deposit
initial   and  variation  margin  pursuant  to  requirements  similar  to  those
applicable to Futures Contracts. Premiums received from the writing of an option
on a Futures Contract are included in the initial margin deposit.
 
A Fund may seek to  close out an option position  by selling an option  covering
the  same Futures  Contract and  having the  same exercise  price and expiration
date. The  ability to  establish and  close  out positions  on such  options  is
subject to the maintenance of a liquid secondary market.
 
LIMITATIONS  ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS ON
CURRENCIES
   
To the extent  that a  Fund enters into  Futures Contracts,  options on  Futures
Contracts,  and  options  on  foreign  currencies  traded  on  a  CFTC-regulated
exchange, in each case other than for BONA FIDE hedging purposes (as defined  by
the CFTC), the aggregate initial margin and premiums required to establish those
positions  (excluding the amount  by which options  are "in-the-money") will not
exceed 5% of the  liquidation value of the  Fund's portfolio, after taking  into
account  unrealized profits and unrealized losses  on any contracts the Fund has
entered  into.  In   general,  a   call  option   on  a   Futures  Contract   is
"in-the-money"if  the  value  of  the underlying  Futures  Contract  exceeds the
strike, i.e., exercise, price of the call; a put option on a Futures Contract is
"in-the-money" if the value  of the underlying Futures  Contract is exceeded  by
the strike price of the put. This guideline may be modified by the Trust's Board
of  Trustees  without a  shareholder vote.  This limitation  does not  limit the
percentage of the Fund's assets at risk to 5%.
    
 
FORWARD CONTRACTS
A Forward Contract is an obligation, usually arranged with a commercial bank  or
other  currency dealer, to purchase or  sell a currency against another currency
at a future  date and price  as agreed upon  by the parties.  A Fund either  may
accept or make delivery of the currency at the maturity of the Forward Contract.
The  Fund may also, if its contra party  agrees, prior to maturity, enter into a
closing transaction involving the purchase or sale of an offsetting contract.

                         AIM LATIN AMERICAN GROWTH FUND
 
A Fund  engages in  forward  currency transactions  in  anticipation of,  or  to
protect  itself against,  fluctuations in  exchange rates.  A Fund  might sell a
particular  foreign  currency  forward,  for   example,  when  it  holds   bonds
denominated  in a  foreign currency but  anticipates, and seeks  to be protected
against, a decline in the currency against the U.S. dollar. Similarly, the  Fund
might  sell the  U.S. dollar  forward when  it holds  bonds denominated  in U.S.
dollars but anticipates,  and seeks to  be protected against,  a decline in  the
U.S.  dollar relative  to other currencies.  Further, the Fund  might purchase a
currency forward  to "lock  in"  the price  of  securities denominated  in  that
currency that it anticipates purchasing.
 
   
Forward  Contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement and no commissions are charged  at
any  stage for  trades. Each  Fund will enter  into such  Forward Contracts with
major U.S. or  foreign banks and  securities or currency  dealers in  accordance
with the guidelines approved by the Trust's Board of Trustees.
    
 
Each  Fund  may enter  into Forward  Contracts either  with respect  to specific
transactions or  with respect  to the  Fund's portfolio  positions. The  precise
matching  of the Forward  Contract amounts and the  value of specific securities
generally will not be  possible because the future  value of such securities  in
foreign currencies will change as a consequence of market movements in the value
of  those securities between the  date the Forward Contract  is entered into and
the date it matures.  Accordingly, it may  be necessary for  a Fund to  purchase
additional  foreign  currency on  the  spot (I.E.,  cash)  market (and  bear the
expense of such purchase) if the market  value of the security is less than  the
amount of foreign currency the Fund is obligated to deliver and if a decision is
made to sell the security and make delivery of the foreign currency. Conversely,
it  may be necessary to sell on the spot market some of the foreign currency the
Fund is  obligated to  deliver.  The projection  of short-term  currency  market
movements  is extremely difficult, and the  successful execution of a short-term
hedging strategy is highly  uncertain. Forward Contracts  involve the risk  that
anticipated  currency movements will not be predicted accurately, causing a Fund
to sustain losses on these contracts and transaction costs.
 
At or before  the maturity  of a  Forward Contract requiring  a Fund  to sell  a
currency,  the  Fund either  may  sell a  portfolio  security and  use  the sale
proceeds to make delivery of the currency or retain the security and offset  its
contractual  obligation to deliver the currency  by purchasing a second contract
pursuant to which  the Fund will  obtain, on  the same maturity  date, the  same
amount  of the currency that  it is obligated to  deliver. Similarly, a Fund may
close out a Forward  Contract requiring it to  purchase a specified currency  by
entering  into a second  contract, if its  contra party agrees,  entitling it to
sell the same  amount of the  same currency on  the maturity date  of the  first
contract.  The Fund would  realize a gain or  loss as a  result of entering into
such an offsetting Forward Contract under either circumstance to the extent  the
exchange  rate  or  rates  between the  currencies  involved  moved  between the
execution dates of the first contract and the offsetting contract.
 
The cost to a Fund of engaging in Forward Contracts varies with factors such  as
the  currencies  involved, the  length  of the  contract  period and  the market
conditions then prevailing. Because Forward  Contracts usually are entered  into
on  a principal basis, no  fees or commissions are  involved. The use of Forward
Contracts does  not  eliminate fluctuations  in  the prices  of  the  underlying
securities  a Fund owns or  intends to acquire, but it  does establish a rate of
exchange in advance. In addition, while Forward Contract sales limit the risk of
loss due to a decline in the value of the hedged currencies, they also limit any
potential gain that might result should the value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
Each Fund may use options on foreign currencies, Futures on foreign  currencies,
options  on Futures on foreign currencies and Forward Contracts to hedge against
movements in the values of the foreign currencies in which the Fund's securities
are denominated. Such currency hedges can  protect against price movements in  a
security that a Fund owns or intends to acquire that are attributable to changes
in  the value of  the currency in which  it is denominated.  Such hedges do not,
however, protect against price movements in the securities that are attributable
to other causes.
 
A Fund might seek to hedge against changes in the value of a particular currency
when no Futures Contract, Forward Contract or option involving that currency  is
available  or  one  of  such  contracts is  more  expensive  than  certain other
contracts. In  such cases,  a Fund  may hedge  against price  movements in  that
currency  by  entering  into  a  contract  on  another  currency  or  basket  of
currencies, the values of  which the Sub-adviser believes  will have a  positive
correlation  to the value of the currency  being hedged. The risk that movements
in the price of the contract will not correlate perfectly with movements in  the
price of the currency being hedged is magnified when this strategy is used.
 
The value of Futures Contracts, options on Futures Contracts, Forward Contracts,
and  options  on  foreign currencies  depends  on  the value  of  the underlying
currency relative  to the  U.S. dollar.  Because foreign  currency  transactions

                         AIM LATIN AMERICAN GROWTH FUND
occurring  in the  interbank market  might involve  substantially larger amounts
than those  involved in  the  use of  Futures  Contracts, Forward  Contracts  or
options,  a  Fund  could be  disadvantaged  by  dealing in  the  odd  lot market
(generally  consisting  of  transactions  of  less  than  $1  million)  for  the
underlying  foreign currencies at prices that  are less favorable than for round
lots.
 
There is no systematic reporting of last sale information for foreign currencies
or any  regulatory requirements  that quotations  available through  dealers  or
other market sources be firm or revised on a timely basis. Quotation information
generally  is representative of very large  transactions in the interbank market
and thus  might not  reflect  odd-lot transactions  where  rates might  be  less
favorable.   The   interbank  market   in  foreign   currencies  is   a  global,
round-the-clock market. To the  extent the U.S. options  or Futures markets  are
closed  while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that  cannot
be  reflected in  the markets  for the Futures  contracts or  options until they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies might  be required  to  take place  within  the country  issuing  the
underlying  currency. Thus, a Fund might be  required to accept or make delivery
of the  underlying foreign  currency  in accordance  with  any U.S.  or  foreign
regulations  regarding the maintenance  of foreign banking  arrangements by U.S.
residents and might be  required to pay any  fees, taxes and charges  associated
with such delivery assessed in the issuing country.
 
COVER
Transactions  using Forward Contracts, Futures Contracts and options (other than
options purchased by a Fund) expose the Fund to an obligation to another  party.
No  Fund will  enter into  any such  transactions unless  it owns  either (1) an
offsetting ("covered")  position in  securities, currencies,  or other  options,
Forward  Contracts or Futures Contracts, or (2) cash, receivables and short-term
debt securities with  a value  sufficient at all  times to  cover its  potential
obligations not covered as provided in (1) above. The Funds will comply with SEC
guidelines  regarding  cover for  these instruments  and,  if the  guidelines so
require, set aside cash or liquid securities.
 
Assets used as cover or  held in a segregated account  cannot be sold while  the
position  in the corresponding  Forward Contract, Futures  Contract or option is
open, unless they are replaced with other appropriate assets. If a large portion
of a Fund's assets are  used for cover or otherwise  set aside, it could  affect
portfolio  management or the Fund's ability to meet redemption requests or other
current obligations.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
Developing Markets Fund and Emerging Markets Fund  each may invest up to 15%  of
its net assets, and Latin American Fund up to 10% of its net assets, in illiquid
securities.  Securities may be  considered illiquid if  a Fund cannot reasonably
expect within seven days  to sell the security  for approximately the amount  at
which  the Fund values such securities. The sale of illiquid securities, if they
can be  sold at  all, generally  will require  more time  and result  in  higher
brokerage  charges or dealer discounts and  other selling expenses than the sale
of liquid securities, such as securities eligible for trading on U.S. securities
exchanges or in  the over-the-counter markets.  Moreover, restricted  securities
which may be illiquid for purposes of this limitation, often sell, if at all, at
a  price lower than similar  securities that are not  subject to restrictions on
resale.
 
Illiquid securities include those that are subject to restrictions contained  in
the  securities laws  of other  countries. However,  securities that  are freely
marketable in the country  where they are principally  traded, but would not  be
freely  marketable in the United States,  will not be considered illiquid. Where
registration is required,  a Fund may  be obligated to  pay all or  part of  the
registration  expenses and a considerable period  may elapse between the time of
the decision to sell and the time the  Fund may be permitted to sell a  security
under  an effective  registration statement. If,  during such  a period, adverse
market conditions were to develop, the Fund might obtain a less favorable  price
than prevailed when it decided to sell.

                         AIM LATIN AMERICAN GROWTH FUND
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under the Securities Act of 1933, as amended ("1933 Act"), including
private placements, repurchase agreements, commercial paper, foreign  securities
and corporate bonds and notes. These instruments are often restricted securities
because  the  securities are  sold in  transactions not  requiring registration.
Institutional investors generally will not seek to sell these instruments to the
general  public,  but  instead  will   often  depend  either  on  an   efficient
institutional market in which such unregistered securities can be readily resold
or  on an issuer's ability to honor  a demand for repayment. Therefore, the fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the  1933 Act  for resales  of certain  securities to qualified
institutional buyers.  Institutional  markets  for  restricted  securities  have
developed  as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to  satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance  and  settlement of  unregistered securities  of domestic  and foreign
issuers, such as  the PORTAL  System sponsored  by the  National Association  of
Securities  Dealers,  Inc.  An insufficient  number  of  qualified institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a Fund,  however, could  affect adversely  the marketability  of such  portfolio
securities  and the Fund might be unable  to dispose of such securities promptly
or at favorable prices.
 
   
With respect  to  liquidity  determinations  generally,  the  Trust's  Board  of
Trustees  has  the  ultimate  responsibility  for  determining  whether specific
securities, including restricted securities pursuant to Rule 144A under the 1933
Act, are liquid  or illiquid.  The Board has  delegated the  function of  making
day-to-day  determinations of  liquidity to  the Sub-adviser  in accordance with
procedures approved by the Board. The Sub-adviser takes into account a number of
factors in reaching liquidity decisions, including (i) the frequency of  trading
in  the security, (ii) the  number of dealers who  make quotes for the security,
(iii) the  number  of dealers  who  have undertaken  to  make a  market  in  the
security,  (iv) the number of  other potential purchasers and  (v) the nature of
the security and  how trading is  effected (e.g.,  the time needed  to sell  the
security,  how  offers  are  solicited  and  the  mechanics  of  transfer).  The
Sub-adviser monitors the liquidity  of securities in  each Fund's portfolio  and
periodically  reports  such  determinations  to  the  Board.  If  the  liquidity
percentage restriction of a Fund is satisfied at the time of investment, a later
increase in the  percentage of illiquid  securities held by  the Fund  resulting
from  a change in market value or assets will not constitute a violation of that
restriction. If  as  a  result of  a  change  in market  value  or  assets,  the
percentage  of illiquid securities held by a Fund increases above the applicable
limit, the Sub-adviser will take appropriate steps to bring the aggregate amount
of illiquid assets back within the prescribed limitations as soon as  reasonably
practicable, taking into account the effect of any disposition on the Fund.
    
 
FOREIGN SECURITIES
 
    POLITICAL,  SOCIAL AND ECONOMIC  RISKS. Investing in  securities of non-U.S.
companies may entail additional risks due to the potential political, social and
economic instability  of  certain  countries and  the  risks  of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment, convertibility of currencies into  U.S. dollars and on  repatriation
of  capital invested.  In the  event of  such expropriation,  nationalization or
other confiscation by any  country, a Fund could  lose its entire investment  in
any such country.
 
In  addition, even  though opportunities  for investment  may exist  in emerging
markets, any change in  the leadership or policies  of the governments of  those
countries  or  in  the leadership  or  policies  of any  other  government which
exercises a significant influence over  those countries, may halt the  expansion
of  or reverse the  liberalization of foreign  investment policies now occurring
and thereby eliminate any investment opportunities which may currently exist.
 
Investors should note that upon the accession to power of authoritarian regimes,
the governments of a number of Latin American countries previously  expropriated
large  quantities of  real and personal  property similar to  the property which
will be represented  by the  securities purchased by  the Funds.  The claims  of
property  owners against those governments were never finally settled. There can
be no assurance  that any property  represented by securities  purchased by  the
Funds  will not also be expropriated, nationalized, or otherwise confiscated. If
such confiscation were to occur, the Funds could lose their entire investment in
such countries. The Funds' investments would similarly be adversely affected  by
exchange control regulation in any of those countries.
 
    RELIGIOUS  AND ETHNIC  STABILITY. Certain countries  in which  the Funds may
invest  may  have  groups  that  advocate  radical  religious  or  revolutionary
philosophies or support ethnic independence. Any disturbance on the part of such
individuals could carry the potential for widespread destruction or confiscation
of  property owned by individuals and entities foreign to such country and could
cause the loss of a Fund's  investment in those countries. Instability may  also
result from, among

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
other things, (i) authoritarian governments or military involvement in political
and   economic   decision-making,  including   changes  in   government  through
extra-constitutional means,  (ii) popular  unrest  associated with  demands  for
improved  political, economic and social  conditions and (iii) hostile relations
with neighboring  or  other  countries.  Such  political,  social  and  economic
instability  could disrupt  the principal financial  markets in  which the Funds
invest and adversely affect the value of the Funds' assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity markets, by foreign entities such as the Funds. These  restrictions
or  controls may at times limit or preclude investment in certain securities and
may increase the cost and expenses of the Funds. For example, certain  countries
require prior governmental approval before investments by foreign persons may be
made  or may limit the  amount of investment by  foreign persons in a particular
company, or limit the investment by foreign persons to only a specific class  of
securities of a company that may have less advantageous terms than securities of
the company available for purchase by nationals. Moreover, the national policies
of  certain  countries  may  restrict  investment  opportunities  in  issuers or
industries deemed sensitive to national  interests. In addition, some  countries
require governmental approval for the repatriation of investment income, capital
or  the  proceeds  of securities  sales  by  foreign investors.  If  there  is a
deterioration in a country's balance of payments or for other reasons, a country
may impose restrictions on foreign  capital remittances abroad. The Funds  could
be  adversely  affected  by delays  in,  or  a refusal  to  grant,  any required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
 
   
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that  differ in some  cases significantly from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting principles. Most  of the securities held  by the Funds  will
not  be registered with the  SEC or regulators of  any foreign country, nor will
the issuers thereof be subject to the SEC's reporting requirements. Thus,  there
will be less available information concerning most foreign issuers of securities
held  by the Funds than is available concerning U.S. issuers. In instances where
the financial statements of an issuer  are not deemed to reflect accurately  the
financial  situation of the issuer, the  Sub-adviser will take appropriate steps
to evaluate the proposed investment, which may include on-site inspection of the
issuer, interviews  with  its  management and  consultations  with  accountants,
bankers  and other specialists.  There is substantially  less publicly available
information about foreign companies than there are reports and ratings published
about U.S.  companies  and  the  U.S.  government.  In  addition,  where  public
information  is  available,  it  may  be  less  reliable  than  such information
regarding U.S.  issuers.  Issuers of  securities  on foreign  jurisdictions  are
generally  not subject to the same degree of regulation as are U.S. issuers with
respect to such matters as restrictions on market manipulation, insider  trading
rules,  shareholder proxy requirements and  timely disclosure of information. In
addition,  for  companies  that  keep  accounting  records  in  local  currency,
inflation  accounting rules in  some Latin American  countries require, for both
tax and accounting purposes, that certain assets and liabilities be restated  on
the  company's balance sheet in  order to express items  in terms of currency of
constant purchasing power. Inflation  accounting may indirectly generate  losses
or profits.
    
 
    CURRENCY  FLUCTUATIONS. Because the Funds,  under normal circumstances, each
will invest  a substantial  portion of  its total  assets in  the securities  of
foreign  issuers which  are denominated in  foreign currencies,  the strength or
weakness of the  U.S. dollar against  such foreign currencies  will account  for
part  of  each Fund's  investment performance.  A  decline in  the value  of any
particular currency against  the U.S. dollar  will cause a  decline in the  U.S.
dollar  value of a  Fund's holdings of  securities and cash  denominated in such
currency and, therefore, will cause an  overall decline in the Fund's net  asset
value  and  any  net  investment  income and  capital  gains  derived  from such
securities to  be distributed  in U.S.  dollars to  shareholders of  that  Fund.
Moreover,  if the value of  the foreign currencies in  which a Fund receives its
income falls relative to the U.S. dollar  between receipt of the income and  the
making  of Fund distributions, the Fund  may be required to liquidate securities
in order to make distributions if the Fund has insufficient cash in U.S. dollars
to meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors including  the supply and  demand for particular currencies,
central bank efforts to support particular currencies, the movement of  interest
rates,  the pace of business activity in  certain other countries and the United
States, and other economic and financial conditions affecting the world economy.

                         AIM LATIN AMERICAN GROWTH FUND
 
Although the Funds value their  assets daily in terms  of U.S. dollars, they  do
not  intend to convert their holdings of foreign currencies into U.S. dollars on
a daily basis. The Funds will do so  from time to time, and investors should  be
aware  of the costs of currency conversion. Although foreign exchange dealers do
not charge  a  fee  for conversion,  they  do  realize a  profit  based  on  the
difference  ("spread") between the  prices at which they  are buying and selling
various currencies. Thus, a  dealer may offer  to sell a  foreign currency to  a
Fund  at one rate, while offering a lesser rate of exchange should a Fund desire
to sell that currency to the dealer.
 
Certain  Latin  American  countries  may  have  managed  currencies  which   are
maintained  at  artificial  levels to  the  U.S.  dollar rather  than  at levels
determined by the  market. This  type of  system can  lead to  sudden and  large
adjustments  in the currency which, in turn,  can have a disruptive and negative
effect on foreign investors. For example, in late 1994 the value of the  Mexican
peso lost more than one-third of its value relative to the dollar. Certain Latin
American  countries also may restrict the free conversion of their currency into
foreign currencies, including the U.S.  dollar. There is no significant  foreign
exchange  market for certain currencies and it  would, as a result, be difficult
for the Funds to engage in foreign currency transactions designed to protect the
value of the Funds' interests in securities denominated in such currencies.
 
    ADVERSE MARKET CHARACTERISTICS.  Securities of many  foreign issuers may  be
less  liquid and their  prices more volatile than  securities of comparable U.S.
issuers. In  addition,  foreign securities  markets  and brokers  generally  are
subject  to  less governmental  supervision and  regulation  than in  the United
States  and  foreign  securities  transactions  usually  are  subject  to  fixed
commissions,  which  generally are  higher than  negotiated commissions  on U.S.
transactions. In addition,  foreign securities  transactions may  be subject  to
difficulties  associated  with the  settlement of  such transactions.  Delays in
settlement could  result in  temporary  periods when  assets  of the  Funds  are
uninvested  and no  return is earned  thereon. The  inability of a  Fund to make
intended security purchases due to settlement  problems could cause the Fund  to
miss  attractive opportunities. Inability to dispose of a portfolio security due
to settlement problems either could result in losses to a Fund due to subsequent
declines in value of the portfolio security  or, if the Fund has entered into  a
contract  to  sell  the security,  could  result  in possible  liability  to the
purchaser. The Sub-adviser will consider such difficulties when determining  the
allocation  of the Funds' assets, although the Sub-adviser does not believe that
such difficulties will have  a material adverse effect  on the Funds'  portfolio
trading activities.
 
Each  Fund may use  foreign custodians, which  may involve risks  in addition to
those related to the  use of U.S. custodians.  Such risks include  uncertainties
relating  to (i) determining  and monitoring the  financial strength, reputation
and standing of the foreign  custodian, (ii) maintaining appropriate  safeguards
to protect a Fund's investments and (iii) possible difficulties in obtaining and
enforcing judgments against such custodians.
 
A  high proportion of the shares of many Latin American companies may be held by
a limited  number of  persons, which  may  further limit  the number  of  shares
available  for  investment by  the Funds,  particularly  Latin American  Fund. A
limited number of issuers in most, if not all, Latin American securities markets
may represent a disproportionately large percentage of market capitalization and
trading value. The limited liquidity  of Latin American securities markets  also
may affect a Fund's ability to acquire or dispose of securities at the price and
time it wishes to do so. In addition, certain Latin American securities markets,
including those of Argentina, Brazil, Chile and Mexico, are susceptible to being
influenced  by large  investors trading significant  blocks of  securities or by
large dispositions of securities resulting from the failure to meet margin calls
when due.
 
The high volatility of certain Latin American securities markets is evidenced by
dramatic movements in the  Brazilian and Mexican markets  in recent years.  This
market  volatility may result in greater volatility  in a Fund's net asset value
than would be the case for companies investing in domestic securities. If a Fund
were to  experience unexpected  net  redemptions, it  could  be forced  to  sell
securities  in  its  portfolio  without  regard  to  investment  merit,  thereby
decreasing the asset base  over which Fund expenses  can be spread and  possibly
reducing the Fund's rate of return.
 
    WITHHOLDING  TAXES.  Each Fund's  net investment  income from  securities of
foreign issuers may  be subject  to withholding  taxes by  the foreign  issuer's
country,  thereby reducing that  income or delaying the  receipt of income where
those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION. To the  extent a Fund  invests a significant  portion of  its
assets in securities of issuers located in a particular country or region of the
world,  it may be subject to greater risks and may experience greater volatility
than a fund that is more broadly diversified geographically.
 
    SPECIAL CONSIDERATIONS  AFFECTING  EMERGING  MARKETS.  Investing  in  equity
securities  of  companies  in emerging  markets  may entail  greater  risks than
investing in equity securities in  developed countries. These risks include  (i)
less social, political

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
and  economic stability;  (ii) the  small current size  of the  markets for such
securities and the currently low or nonexistent volume of trading, which  result
in  a lack of liquidity and in  greater price volatility; (iii) certain national
policies  which  may  restrict  a  Fund's  investment  opportunities,  including
restrictions on investment in issuers or industries deemed sensitive to national
interests;  (iv) foreign taxation;  and (v) the  absence of developed structures
governing private or  foreign investment  or allowing for  judicial redress  for
injury to private property.
 
   
Investing  in the  securities of  companies in  emerging markets,  including the
markets of Latin America and certain Asian markets such as Taiwan, Malaysia  and
Indonesia, may entail special risks relating to potential political and economic
instability and the risks of expropriation, nationalization, confiscation or the
imposition  of  restrictions  on foreign  investment,  convertibility  into U.S.
dollars  and  on  repatriation  of  capital  invested.  In  the  event  of  such
expropriation,  nationalization  or other  confiscation by  any country,  a Fund
could lose its entire investment in any such country.
    
 
   
Emerging  securities  markets,  such  as  the  markets  of  Latin  America,  are
substantially  smaller, less developed,  less liquid and  more volatile than the
major securities markets. The  limited size of  emerging securities markets  and
limited  trading value  in issuers  compared to  the volume  of trading  in U.S.
securities could cause prices to be erratic for reasons apart from factors  that
affect the quality of the securities. For example, limited market size may cause
prices  to be unduly influenced by  traders who control large positions. Adverse
publicity and  investors'  perceptions,  whether or  not  based  on  fundamental
analysis,  may  decrease  the  value  and  liquidity  of  portfolio  securities,
especially in these markets. In addition, securities traded in certain  emerging
markets   may  be  subject  to  risks  due  to  the  inexperience  of  financial
intermediaries, a lack of  modern technology, the lack  of a sufficient  capital
base  to  expand  business  operations,  and  the  possibility  of  permanent or
temporary termination of trading.
    
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in more developed markets.  In such emerging securities there may
be share registration and delivery delays or failures.
 
   
Many emerging  market  countries,  including  markets  in  Latin  America,  have
experienced  substantial, and in some periods extremely high, rates of inflation
for many years. This has, in turn, lead to high interest rates, extreme measures
by governments to keep inflation in check and a generally debilitating effect on
economic growth.  Inflation  and  rapid  fluctuations  in  inflation  rates  and
corresponding  currency devaluations have had and  may continue to have negative
effects on  the economies  and  securities markets  of certain  emerging  market
countries, including markets in Latin America.
    
 
    SPECIAL  CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN COUNTRIES.
Investing in Russia  and Eastern European  countries involves a  high degree  of
risk  and special considerations not typically  associated with investing in the
U.S. securities markets and should be considered highly speculative. Such  risks
include the following: (1) delays in settling portfolio transactions and risk of
loss  arising out of the system of  share registration and custody; (2) the risk
that it may be impossible  or more difficult than  in other countries to  obtain
and/or  enforce a  judgement; (3) pervasiveness  of corruption and  crime in the
economic system; (4) currency exchange rate volatility and the lack of available
currency hedging instruments; (5) higher rates of inflation (including the  risk
of   social  unrest  associated  with   periods  of  hyper-inflation)  and  high
unemployment; (6) controls on foreign investment and local practices disfavoring
foreign investors and limitations on  repatriation of invested capital,  profits
and  dividends,  and on  the  ability of  Developing  Markets Fund  and Emerging
Markets Fund  to  exchange local  currencies  for U.S.  dollars;  (7)  political
instability and social unrest and violence; (8) the risk that the governments of
Russia  and Eastern European countries may decide not to continue to support the
economic  reform  programs  implemented  recently  and  could  follow  radically
different  political  and/or economic  policies to  the detriment  of investors,
including non-market-oriented policies such as the support of certain industries
at the expense  of other  sectors or  investors, or  a return  to the  centrally
planned  economy  that  existed when  such  countries  had a  communist  form of
government; (9)  the  financial  condition  of  companies  in  these  countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of  international trade; (11)  the risk that  the tax system  in these countries
will not  be reformed  to prevent  inconsistent, retroactive  and/or  exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.

Many of the Asia Pacific region countries may be subject to a greater degree  of
social,  political  and economic  instability  than is  the  case in  the United
States. Such instability may result from, among other things, the following: (i)
authoritarian governments  or military  involvement  in political  and  economic
decision  making, and changes in  government through extra-constitutional means;
(ii) popular unrest associated with demands for improved political, economic and
social conditions;  (iii) internal  insurgencies;  (iv) hostile  relations  with
neighboring  countries; and (v) ethnic,  religious and racial disaffection. Such
social, political  and  economic  instability could  significantly  disrupt  the
principal  financial  markets  in  which Developing  Markets  Fund  and Emerging
Markets Fund invest  and adversely affect  the value of  such Funds' assets.  In
addition,  asset  expropriations  or  future  confiscatory  levels  of  taxation
possibly may affect the Funds.
 
Several of the  Asia Pacific region  countries have,  or in the  past have  had,
hostile  relationships  with neighboring  nations  or have  experienced internal
insurgency. Thailand has  experienced border conflicts  with Laos and  Cambodia,
and India is engaged in border disputes with several of its neighbors, including
China  and Pakistan. An uneasy truce exists between North Korea and South Korea,
and the recurrence of hostilities remains possible. Reunification of North Korea
and South Korea could have a detrimental  effect on the economy of South  Korea.
Also,  China  continues  to  claim  sovereignty  over  Taiwan  and  recently has
conducted military maneuvers near Taiwan.
 
The economies of most of the Asia Pacific region countries are heavily dependent
upon international  trade  and  are accordingly  affected  by  protective  trade
barriers  and the economic conditions of their trading partners, principally the
United States, Japan,  China and the  European Community. The  enactment by  the
United  States  or  other  principal  trading  partners  of  protectionist trade
legislation, reduction of foreign investment in the local economies and  general
declines  in  the  international  securities markets  could  have  a significant
adverse effect upon the securities markets of the Asia Pacific region countries.
In addition,  the  economies of  some  of  the Asia  Pacific  region  countries,
Australia and Indonesia, for example, are vulnerable to weakness in world prices
for their commodity exports, including crude oil.
 
China  recently assumed sovereignty over Hong  Kong in July 1997. Although China
has committed by treaty to preserve the economic and social freedoms enjoyed  in
Hong  Kong for fifty years, the continuation of the current form of the economic
system in Hong Kong will  depend on the actions of  the government of China.  In
addition,  such assumption of sovereignty has increased sensitivity in Hong Kong
to political developments and  statements by public  figures in China.  Business
confidence  in  Hong  Kong, therefore,  can  be significantly  affected  by such
developments and  statements, which  in  turn can  affect markets  and  business
performance.
 
   
In addition, there is continuing risk that the Hong Kong dollar will be devalued
and  a risk of possible loss of investor confidence in the Hong Kong markets and
dollar. However, factors  exist that are  likely to mitigate  this risk.  First,
China has stated its intention to implement a "one country, two systems" policy,
which  would preserve monetary sovereignty and leave control in the hands of the
Hong Kong Monetary Authority ("HKMA").
    
 
   
Second, fixed  rate  parity  with  the  U.S.  dollar  is  seen  as  critical  to
maintaining  investors'  confidence  in  the transition  to  Chinese  rule, and,
therefore, it is anticipated that, if international investors lose confidence in
Hong Kong dollar  assets, the  HKMA would take  steps to  support the  currency,
though  the  taking of  such steps  cannot  be assured.  Third, Hong  Kong's and
China's sizable combined  foreign exchange reserve  may be used  to support  the
value  of the Hong  Kong dollar, provided  that China does  not appropriate such
reserves for  other  uses, which  is  not  anticipated but  cannot  be  assured.
Finally,  China would be likely to  experience significant adverse political and
economic consequences if confidence  in the Hong Kong  dollar and the  territory
assets were to be endangered.
    
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.

                         AIM LATIN AMERICAN GROWTH FUND
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
It should  be noted  that  some Latin  American countries  require  governmental
approval  for the repatriation of investment  income, capital or the proceeds of
securities sales  by  foreign  investors.  For  instance,  at  present,  capital
invested directly in Chile cannot under most circumstances be repatriated for at
least  one year. The Funds, particularly Latin American Fund, could be adversely
affected by delays in, or a refusal to grant, any required governmental approval
for repatriation, as well as by the  application to it of other restrictions  on
investments.
 
    SOVEREIGN  DEBT. Sovereign Debt generally offers high yields, reflecting not
only perceived  credit risk,  but also  the  need to  compete with  other  local
investments  in domestic financial markets. Certain Latin American countries are
among the  largest  debtors  to  commercial banks  and  foreign  governments.  A
sovereign debtor's willingness or ability to repay principal and interest due in
a  timely  manner  may  be  affected by,  among  other  factors,  its  cash flow
situation, the extent of  its foreign reserves,  the availability of  sufficient
foreign  exchange on the  date a payment is  due, the relative  size of the debt
service burden to the economy as a whole, the sovereign debtor's policy  towards
the  International  Monetary  Fund  and the  political  constraints  to  which a
sovereign debtor  may  be  subject.  Sovereign  debtors  may  default  on  their
Sovereign   Debt.  Sovereign   debtors  may   also  be   dependent  on  expected
disbursements from foreign governments, multilateral agencies and others  abroad
to reduce principal and interest arrearages on their debt. The commitment on the
part of these governments, agencies and others to make such disbursements may be
conditioned  on a sovereign  debtor's implementation of  economic reforms and/or
economic performance  and  the  timely service  of  such  debtor's  obligations.
Failure  to implement such reforms, achieve  such levels of economic performance
or repay principal or interest when due, may result in the cancellation of  such
third  parties' commitments  to lend  funds to  the sovereign  debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
 
In recent years, some of the Latin American countries in which the Funds  expect
to  invest have encountered difficulties in servicing their Sovereign Debt. Some
of these  countries  have withheld  payments  of interest  and/or  principal  of
Sovereign  Debt. These difficulties  have also led  to agreements to restructure
external debt obligations -- in particular, commercial bank loans, typically  by
rescheduling  principal  payments,  reducing interest  rates  and  extending new
credits to finance interest payments on existing debt. In the future, holders of
Sovereign Debt may be requested to participate in similar reschedulings of  such
debt.
 
   
The  ability  of Latin  American governments  to make  timely payments  on their
Sovereign Debt is  likely to be  influenced strongly by  a country's balance  of
trade  and its access to trade and  other international credits. A country whose
exports are concentrated in a few  commodities could be vulnerable to a  decline
in  the  international prices  of  one or  more  of such  commodities. Increased
protectionism on the part of a  country's trading partners could also  adversely
affect  its  exports.  Such  events could  diminish  a  country's  trade account
surplus, if any. To the extent that  a country receives payment for its  exports
in  currencies other  than hard  currencies, its  ability to  make hard currency
payments could be affected.
    
 
The occurrence of political, social or diplomatic changes in one or more of  the
countries  issuing Sovereign Debt  could adversely affect  a Fund's investments.
The countries  issuing such  instruments  are faced  with social  and  political
issues and some of them have experienced high rates of inflation in recent years
and  have  extensive  internal debt.  Among  other effects,  high  inflation and
internal  debt  service   requirements  may  adversely   affect  the  cost   and
availability  of  future domestic  sovereign  borrowing to  finance governmental
programs,  and  may   have  other   adverse  social,   political  and   economic
consequences.  Political  changes or  a  deterioration of  a  country's domestic
economy or balance of trade may  affect the willingness of countries to  service
their  Sovereign  Debt.  While the  Sub-adviser  intends to  manage  each Fund's
portfolio in a manner that will minimize  the exposure to such risks, there  can
be  no assurance  that adverse  political changes  will not  cause the  Funds to
suffer losses of interest or principal on any of their holdings.
 
Periods of economic uncertainty may result in the volatility of market prices of
Sovereign Debt and in turn, a Fund's  net asset value, to a greater extent  than
the volatility inherent in domestic securities. The value of Sovereign Debt will
likely  vary  inversely with  changes in  prevailing  interest rates,  which are
subject to considerable variance in the international market. If a Fund were  to
experience  unexpected net redemptions, it may  be forced to sell Sovereign Debt
in its  portfolio without  regard to  investment merit,  thereby decreasing  its
asset base over which Fund expenses can be spread and possibly reducing its rate
of return.

DEVELOPING MARKETS FUND
   
Developing  Markets Fund's investment objectives may  not be changed without the
approval of  a  majority of  its  outstanding shares.  In  addition,  Developing
Markets  Fund has adopted the  following fundamental investment limitations that
may not be changed without approval of a majority of its outstanding shares.
    
 
Developing Markets Fund may not:
 
        (1) issue senior securities or  borrow money, except as permitted  under
    the  1940 Act and then not in excess of 33 1/3% of Developing Markets Fund's
    total assets (including the amount  borrowed but reduced by any  liabilities
    not  constituting borrowings) at the time  of the borrowing, except that the
    Fund may borrow up to  an additional 5% of  its total assets (not  including
    the amount borrowed) for temporary or emergency purposes;
 
        (2)  purchase any security if, as a result of that purchase, 25% or more
    of Developing Markets Fund's total assets would be invested in securities of
    issuers having their  principal business  activities in  the same  industry,
    except  that  this  limitation  does  not  apply  to  securities  issued  or
    guaranteed by the U.S. government, its agencies or instrumentalities;
 
        (3) engage in the business of underwriting securities of other  issuers,
    except  to the  extent that Developing  Markets Fund might  be considered an
    underwriter under  the  federal  securities  laws  in  connection  with  its
    disposition of portfolio securities;
 
        (4)  purchase or sell real estate, except that investments in securities
    of issuers that  invest in  real estate and  investments in  mortgage-backed
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    Developing Markets Fund  may exercise  rights under  agreements relating  to
    such  securities, including the  right to enforce  security interests and to
    hold real estate  acquired by  reason of  such enforcement  until that  real
    estate can be liquidated in an orderly manner;
 
        (5)  purchase or sell physical  commodities, but Developing Markets Fund
    may purchase, sell or enter into financial options and futures, forward  and
    spot  currency contracts, swap transactions and other financial contracts or
    derivative instruments; or
 
        (6) make loans, except through loans of portfolio securities or  through
    repurchase  agreements, provided that  for purposes of  this limitation, the
    acquisition of bonds, debentures, other  debt securities or instruments,  or
    participations  or  other interests  therein  and investments  in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan.
 
   
Notwithstanding any other investment policy, Developing Markets Fund may  invest
all  of  its  investable assets  (cash,  securities and  receivables  related to
securities) in an  open-end management investment  company having  substantially
the same investment objective, policies and limitations as the Fund.
    
 
For purposes of the concentration policy of Developing Markets Fund contained in
limitation  (2) above, the  Fund intends to  comply with the  SEC staff position
that securities issued  or guaranteed as  to principal and  interest by any  one
single  foreign  government,  or  by  all  supranational  organizations  in  the
aggregate, are considered to be securities of issuers in the same industry.
 
In addition, to  comply with  federal tax  requirements for  qualification as  a
"regulated  investment company"  ("RIC"), Developing  Markets Fund's investments
will be limited so that, at the close  of each quarter of its taxable year,  (a)
not more than 25% of the value of its total assets is invested in the securities
(other  than U.S government securities  or the securities of  other RICs) of any
one issuer and (b) at least 50% of the value of its total assets is  represented
by cash and cash items, U.S. government securities, securities of other RICs and
other  securities, with  these other securities  limited, in respect  of any one
issuer, to an amount that  does not exceed 5% of  the value of its total  assets
and  that does not  represent more than  10% of the  issuer's outstanding voting
securities ("Diversification Requirements").  These tax-related limitations  may

    currency  contracts,  swap  transactions and  other  financial  contracts or
    derivative instruments.
 
Notwithstanding any other investment policy, Latin American Fund may invest  all
of   its  investable  assets  (cash,   securities  and  receivables  related  to
securities) in an  open-end management investment  company having  substantially
the same investment objective, policies and limitations as the Fund.
 
For  purposes  of  Latin  American  Fund's  concentration  policy  contained  in
limitation (1), above, the  Fund intends to comply  with the SEC staff  position
that  securities issued or guaranteed as to principal and interest by any single
foreign government  are considered  to  be securities  of  issuers in  the  same
industry.
 
   
The  following operating  policies of  Latin American  Fund are  not fundamental
policies and may be  changed by vote  of the Trust's  Board of Trustees  without
shareholder approval. Latin American Fund may not:
    
 
        (1)  Invest in  securities of  an issuer  if the  investment would cause
    Latin American Fund to own more than  10% of any class of securities of  any
    one issuer;
 
        (2)  Invest  in  companies  for the  purpose  of  exercising  control or
    management;
 
        (3) Invest  more than  10% of  its net  assets in  illiquid  securities,
    including securities that are illiquid by virtue of the absence of a readily
    available market;
 
        (4)  Enter into a futures contract, an  option on a futures contract, or
    an option on foreign currency traded  on a CFTC-regulated exchange, in  each
    case  other than for BONA FIDE hedging purposes (as defined by the CFTC), if
    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5% of the liquidation value of Latin American Fund's portfolio, after taking
    into account unrealized profits and  unrealized losses on any contracts  the
    Fund has entered into;
 
        (5)  Make any additional investments while borrowings exceed 5% of Latin
    American Fund's total assets;
 
        (6) Purchase securities on margin, provided that Latin American Fund may
    obtain short-term credits as may be necessary for the clearance of purchases
    and sales of securities, and further provided that the Fund may make  margin
    deposits  in  connection  with its  use  of financial  options  and futures,
    forward and spot currency contracts,  swap transactions and other  financial
    contracts or derivative instruments; or
 
        (7)  Mortgage, pledge, or  hypothecate any of  its assets, provided that
    this shall not apply  to the transfer of  securities in connection with  any
    permissible  borrowing  or  to collateral  arrangements  in  connection with
    permissible activities.
 
Latin American Fund has the authority to invest up to 10% of its total assets in
shares of other investment companies pursuant to the 1940 Act. The Fund may  not
invest more than 5% of its total assets in any one investment company or acquire
more than 3% of the outstanding voting securities of any one investment company.
 
   
Investors  should  refer to  the Latin  American  Fund's Prospectus  for further
information with respect  to Latin American  Fund's investment objective,  which
may  not  be  changed  without  the  approval  of  the  shareholders,  and other
investment policies, techniques  and limitations, which  may be changed  without
shareholder approval.

                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject   to  policies  established  by  the  Trust's  Board  of  Trustees,  the
Sub-adviser  is  responsible  for  the   execution  of  each  Fund's   portfolio
transactions  and the selection of  broker/dealers who execute such transactions
on behalf of  the Funds.  In executing portfolio  transactions, the  Sub-adviser
seeks  the best net results  for each Fund, taking  into account such factors as
the price (including the applicable brokerage commission or dealer spread), size
of the order,  difficulty of execution  and operational facilities  of the  firm
involved.  Although  the  Sub-adviser  generally  seeks  reasonably  competitive
commission

                         AIM LATIN AMERICAN GROWTH FUND
rates and spreads, payment of the lowest commission or spread is not necessarily
consistent with the best net results. While the Funds may engage in soft  dollar
arrangements  for  research  services, as  described  below, the  Funds  have no
obligation to deal  with any  broker/dealer or  group of  broker/dealers in  the
execution of portfolio transactions.
 
Debt  securities generally are traded  on a "net" basis  with a dealer acting as
principal for its own account without a stated commission, although the price of
the security  usually  includes  a  profit  to  the  dealer.  U.S.  and  foreign
government  securities and money market instruments  generally are traded in the
OTC markets. In underwritten  offerings, securities usually  are purchased at  a
fixed  price which  includes an  amount of  compensation to  the underwriter. On
occasion, securities may be purchased directly from an issuer, in which case  no
commissions  or discounts  are paid.  Broker/dealers may  receive commissions on
futures, currency and options transactions.
 
   
Consistent with the interests of each  Fund, the Sub-adviser may select  brokers
to  execute a Fund's  portfolio transactions, on  the basis of  the research and
brokerage services they provide to the  Sub-adviser for its use in managing  the
Fund  and  its other  advisory accounts.  Such  services may  include furnishing
analyses, reports and  information concerning  issuers, industries,  securities,
geographic  regions,  economic  factors  and  trends,  portfolio  strategy,  and
performance of accounts;  and effecting securities  transactions and  performing
functions  incidental thereto (such  as clearance and  settlement). Research and
brokerage services received  from such brokers  are in addition  to, and not  in
lieu  of, the  services required  to be performed  by the  Sub-adviser under the
investment management and  administration contracts. A  commission paid to  such
brokers  may  be higher  than  that which  another  qualified broker  would have
charged for  effecting  the  same transaction,  provided  that  the  Sub-adviser
determines  in good faith that such commission  is reasonable in terms either of
that particular transaction or the overall responsibility of the Sub-adviser  to
a  Fund and its other  clients and that the total  commissions paid by that Fund
will be reasonable in relation to the  benefits it received over the long  term.
Research   services  may  also  be  received   from  dealers  who  execute  Fund
transactions in OTC markets.
    
 
The Sub-adviser may allocate brokerage  transactions to broker/dealers who  have
entered  into arrangements under which the  broker/dealer allocates a portion of
the commissions paid by a  Fund toward payment of  the Fund's expenses, such  as
transfer agent and custodian fees.
 
Investment  decisions for each Fund and for other investment accounts managed by
the Sub-adviser  are made  independently of  each other  in light  of  differing
conditions.  However, the same investment decision  occasionally may be made for
two or more of  such accounts including the  Funds. In such cases,  simultaneous
transactions  may occur. Purchases  or sales are  then allocated as  to price or
amount in a manner deemed fair and equitable to all accounts involved. While  in
some cases this practice could have a detrimental effect upon the price or value
of  the security as far as a Fund  is concerned, in other cases, the Sub-adviser
believes that coordination and the ability to participate in volume transactions
will be beneficial to that Fund.
 
   
Under a policy  adopted by the  Trust's Board  of Trustees, and  subject to  the
policy  of  obtaining  the best  net  results,  the Sub-adviser  may  consider a
broker/dealer's sale of the shares of a  Fund and the other funds for which  AIM
or the Sub-adviser serves as investment manager in selecting brokers and dealers
for  the  execution of  portfolio  transactions. This  policy  does not  imply a
commitment to  execute portfolio  transactions through  all broker/dealers  that
sell shares of the Funds and such other funds.
    
 
Each   Fund   contemplates  purchasing   most   foreign  equity   securities  in
over-the-counter markets or stock  exchanges located in  the countries in  which
the  respective principal offices  of the issuers of  the various securities are
located, if that  is the best  available market. The  fixed commissions paid  in
connection  with most such foreign stock  transactions generally are higher than
negotiated commissions on U.S. transactions. There generally is less  government
supervision  and regulation of  foreign stock exchanges and  brokers than in the
United States. Foreign security settlements may in some instances be subject  to
delays and related administrative uncertainties.
 
   
Foreign  equity securities may be  held by each Fund in  the form of ADRs, ADSs,
EDRs, GDRs and CDRs  or securities convertible  into foreign equity  securities.
ADRs,  ADSs, EDRs, GDRs and CDRs may be  listed on stock exchanges, or traded in
the OTC markets in the United States or  Europe, as the case may be. ADRs,  like
other  securities traded  in the  United States,  will be  subject to negotiated
commission rates.  The foreign  and domestic  debt securities  and money  market
instruments in which a Fund may invest generally are traded in the OTC markets.
    
 
   
Each  Fund contemplates that,  consistent with the policy  of obtaining the best
net results, brokerage transactions may  be conducted through certain  companies
affiliated  with AIM or Sub-adviser. The  Trust's Board of Directors has adopted
procedures in conformity with Rule 17e-1 under  the 1940 Act to ensure that  all
brokerage commissions paid to such

affiliates  are reasonable and fair  in the context of  the market in which they
are operating. Any such transactions  will be effected and related  compensation
paid only in accordance with applicable SEC regulations.
 
   
For  the fiscal years  ended December 31,  1997, 1996 and  1995, the Predecessor
Fund  paid  aggregate  brokerage  commissions  of  $2,212,022,  $1,580,879   and
$1,311,090,  respectively. For the fiscal years ended October 31, 1997, 1996 and
1995, Emerging Markets Fund paid aggregate brokerage commissions of  $3,274,528,
$3,648,347  and $3,307,402, respectively. For the fiscal years ended October 31,
1997, 1996 and 1995, Latin American Fund paid aggregate brokerage commissions of
$2,719,660, $2,094,634 and $891,513, respectively.
    
 
PORTFOLIO TRADING AND TURNOVER
Each Fund engages in portfolio trading  when the Sub-adviser has concluded  that
the sale of a security owned by the Fund and/or the purchase of another security
of  better value can enhance principal and/or increase income. A security may be
sold to avoid  any prospective decline  in market  value, or a  security may  be
purchased  in  anticipation  of  a  market  rise.  Consistent  with  each Fund's
investment objective, a  security also  may be  sold and  a comparable  security
purchased  coincidentally in order to take advantage of what is believed to be a
disparity in the normal yield and price relationship between the two securities.
Although none of the  Funds generally intends to  trade for short-term  profits,
the  securities in a Fund's portfolio  will be sold whenever management believes
it is appropriate to do  so, without regard to the  length of time a  particular
security  may have been held. Portfolio  turnover rate is calculated by dividing
the lesser of  sales or purchases  of portfolio securities  by a Fund's  average
month-end  portfolio  values,  excluding short-term  investments.  The portfolio
turnover rate will not be a limiting factor when the Sub-adviser deems portfolio
changes appropriate. Higher portfolio turnover involves correspondingly  greater
brokerage commissions and other transaction costs that a Fund will bear directly
and  may result in  the realization of  net capital gains  that are taxable when
distributed to that Fund's shareholders. For the fiscal years ended December 31,
1997 and 1996,  the Predecessor Fund's  portfolio turnover rates  were 184%  and
138%,  respectively.  For the  fiscal  years ended  October  31, 1997  and 1996,
Emerging  Markets  Fund's   portfolio  turnover  rates   were  150%  and   104%,
respectively.  Latin  American Fund's  portfolio turnover  rates for  the fiscal
years ended October 31, 1997 and 1996 were 130% and 101%, respectively.

- --------------------------------------------------------------------------------
 
INVESTMENT MANAGEMENT AND ADMINISTRATION SERVICES
   
AIM  serves  as  each  Fund's  investment  manager  and  administrator  under an
investment  management  and  administration  contract  ("Management   Contract")
between  the Trust and AIM.  The Sub-adviser serves as  the sub-adviser and sub-
administrator to each Fund under a sub-advisory and sub-administration  contract
between  AIM and the  Sub-adviser ("Sub-Management Contract,"  and together with
the Management Contract, the "Management Contracts"). As investment managers and
administrators, AIM and the  Sub-adviser make all  investment decisions for  the
Funds  and  administer each  Fund's  affairs. Among  other  things, AIM  and the
Sub-adviser furnish the services and pay the compensation and travel expenses of
persons who  perform the  executive,  administrative, clerical  and  bookkeeping
functions  of  the  Trust and  the  Funds,  and provide  suitable  office space,
necessary small office equipment and utilities.
    
 
   
The Management  Contracts for  each  Fund may  be  renewed for  one-year  terms,
provided  that any such renewal has been specifically approved at least annually
by (i) the Trust's Board of Trustees, or  by the vote of a majority of a  Fund's
outstanding  voting securities (as defined in the  1940 Act) and (ii) a majority
of Trustees  who are  not parties  to the  Management Contracts  or  "interested
persons"  of any such  party (as defined in  the 1940 Act), cast  in person at a
meeting called  for  the  specific  purpose of  voting  on  such  approval.  The
Management  Contracts provide that with respect to  each Fund, the Trust or each
of AIM or the Sub-adviser may terminate the Management Contracts without penalty
upon  sixty   days'  written   notice.   The  Management   Contracts   terminate
automatically in the event of their assignment (as defined in the 1940 Act).
    
 
For  the fiscal years ended October 31, 1997, December 31, 1996 and December 31,
1995, the Predecessor Fund of Developing Markets Fund paid investment management
and administration  fees  to  the  Sub-adviser in  the  amounts  of  $7,383,823,
$7,864,840  and $6,878,640, respectively. For the fiscal years ended October 31,
1997, 1996  and  1995, Emerging  Markets  Fund paid  investment  management  and
administration  fees to the Sub-adviser in the amounts of $3,907,922, $4,883,626
and $5,410,744, respectively. For the fiscal years ended October 31, 1997,  1996
and 1995, Latin American Fund paid investment management and administration fees
to  the Sub-adviser  in the  amounts of  $3,538,586, $3,365,375  and $3,913,429,
respectively.
 
DISTRIBUTION SERVICES
   
Each Fund's Advisor  Class shares  are offered continuously  through the  Funds'
principal  underwriter and  distributor, AIM  Distributors, on  a "best efforts"
basis pursuant to a distribution contract between the Trust and AIM Distributors
without a sales charge or a contingent deferred sales charge.
    
 
   
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
    
   
The Transfer Agency  and Service  Agreement between  the Trust  and A  I M  Fund
Services,  Inc. ("AFS"), a registered transfer agent and wholly-owned subsidiary
of AIM, provides  that AFS  will perform  certain shareholder  services for  the
Funds  for a fee per account serviced. The Transfer Agency and Service Agreement
provides that AFS will receive a per account fee plus out-of-pocket expenses  to
process  orders for purchases, redemptions and  exchanges of shares; prepare and
transmit payments  for  dividends  and  distributions  declared  by  the  Funds;
maintain   shareholder  accounts  and   provide  shareholders  with  information
regarding the  Funds  and  their  accounts.  The  Transfer  Agency  and  Service
Agreement  became effective on September 8, 1998. The Sub-adviser serves as each
Fund's pricing and  accounting agent.  For the  fiscal years  ended October  31,
1997,  1996 and 1995, Emerging Markets Fund paid accounting services fees to the
Sub-adviser of  $103,144, $125,349  and $33,216,  and Latin  American Fund  paid
accounting services fees of $90,733, $86,436 and $24,138, respectively.
    
 
EXPENSES OF THE FUNDS
Each   Fund  pays  all  expenses  not  assumed  by  AIM,  the  Sub-adviser,  AIM
Distributors and  other  agents. These  expenses  include, in  addition  to  the
advisory,  distribution,  transfer  agency, pricing  and  accounting  agency and
brokerage fees  discussed  above,  legal and  audit  expenses,  custodian  fees,
directors'   fees,  organizational  fees,  fidelity  bond  and  other  insurance
premiums,  taxes,  extraordinary  expenses  and  the  expenses  of  reports  and
prospectuses sent to existing

investors.  The allocation of  general Trust expenses  and expenses shared among
the Funds and other funds  organized as series of the  Trust are allocated on  a
basis  deemed fair and equitable, which may  be based on the relative net assets
of the Funds or the nature of the services performed and relative  applicability
to  the Funds.  Expenditures, including  costs incurred  in connection  with the
purchase or sale of  portfolio securities, which  are capitalized in  accordance
with   generally  accepted   accounting  principles   applicable  to  investment
companies, are accounted for as capital items and not as expenses. The ratio  of
each  Fund's expenses to  its relative net  assets can be  expected to be higher
than the expense ratios of funds investing solely in domestic securities,  since
the  cost  of maintaining  the custody  of  foreign securities  and the  rate of
investment management  fees paid  by each  Fund generally  are higher  than  the
comparable expenses of such other funds.
    
 
- --------------------------------------------------------------------------------
 
                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
 
   
The  net asset value per  share of each Fund is  normally determined daily as of
the close of  trading of the  New York Stock  Exchange ("NYSE") (generally  4:00
p.m.  Eastern time)  on each business  day of the  Funds. In the  event the NYSE
closes early (i.e., before 4:00 p.m. Eastern time) on a particular day, the  net
asset value of a Fund is determined as of the close of the NYSE on such day. Net
asset  value  per  share  is  determined  by  dividing  the  value  of  a Fund's
securities, cash and other assets (including interest accrued but not collected)
attributable to a particular class, less all its liabilities (including  accrued
expenses  and dividends payable) attributable to that class, by the total number
of shares outstanding  of that  class. Determination  of each  Fund's net  asset
value  per  share  is  made in  accordance  with  generally  accepted accounting
principles.
    
 
   
Each equity security held  by a Fund is  valued at its last  sales price on  the
exchange  where the security  is principally traded  or, lacking any  sales on a
particular day, the security is valued at  the mean between the closing bid  and
asked  prices on that  day. Each security traded  in the over-the-counter market
(but not including securities reported on the NASDAQ National Market System)  is
valued  at the  mean between  the last  bid and  asked prices  based upon quotes
furnished by market makers  for such securities. Each  security reported on  the
NASDAQ National Market System is valued at the last sales price on the valuation
date or absent a last sales price, at the mean between the closing bid and asked
prices  on that day. Debt securities are  valued on the basis of prices provided
by an independent pricing service. Prices provided by the pricing service may be
determined  without  exclusive  reliance  on  quoted  prices,  and  may  reflect
appropriate  factors  such  as  institution-size trading  in  similar  groups of
securities, developments related to  special securities, yield, quality,  coupon
rate,  maturity,  type of  issue, individual  trading characteristics  and other
market data. Securities for which market quotations are not readily available or
are questionable are  valued at fair  value as  determined in good  faith by  or
under  the  supervision  of  the  Trust's  officers  in  a  manner  specifically
authorized by the Board  of Trustees. Short-term obligations  having 60 days  or
less  to maturity  are valued on  the basis  of amortized cost.  For purposes of
determining net asset value per  share, futures and options contracts  generally
will be valued 15 minutes after the close of trading of the NYSE.
    
 
   
Generally,  trading  in  foreign securities,  corporate  bonds,  U.S. Government
securities and money market instruments  is substantially completed each day  at
various times prior to the close of the NYSE. The values of such securities used
in  computing the net asset  value of each Fund's  shares are determined at such
times. Foreign currency exchange rates  are also generally determined prior  the
close  of the NYSE. Occasionally, events affecting the values of such securities
and such exchange rates  may occur between  the times at  which such values  are
determined  and  the  close of  the  NYSE which  will  not be  reflected  in the
computation of a  Fund's net  asset value.  If events  materially affecting  the
value of such securities occur during such period, then these securities will be
valued  at  their  fair  value as  determined  in  good faith  by  or  under the
supervision of the Board of Trustees.

                       HOW TO PURCHASE AND REDEEM SHARES
    
 
- --------------------------------------------------------------------------------
 
   
A complete  description of  the  manner in  which shares  of  the Funds  may  be
purchased appears in the Funds' Prospectuses under the headings "How to Purchase
Shares,"  "Terms  and Conditions  of Purchases  of the  AIM Funds"  and "Special
Plans."
    
 
   
For purposes of  a Letter  of Intent  entered into prior  to June  1, 1998,  any
registered  investment  adviser, trust  company or  bank trust  department which
exercises investment  discretion and  which intends  within thirteen  months  to
invest  $500,000 or more can be treated  as a single purchaser, provided further
that such  entity places  all  purchases and  redemption orders.  Such  entities
should be prepared to establish their qualifications for such treatment.
    
 
   
Complete information concerning the method of exchanging shares of the Funds for
shares of the other AIM Funds is set forth in the Prospectuses under the heading
"Exchange Privilege."
    
 
   
Information  concerning  redemption of  the Funds'  shares is  set forth  in the
Prospectuses under the heading "How to Redeem Shares." In addition to the Funds'
obligation to redeem shares, AIM Distributors  may also repurchase shares as  an
accommodation  to shareholders. To  effect a repurchase,  those dealers who have
executed Selected Dealer Agreements with  AIM Distributors must phone orders  to
the  order desk  of the Funds  at (800)  959-4246 and guarantee  delivery of all
required documents in  good order.  A repurchase is  effected at  the net  asset
value  per share  of the  applicable Fund  next determined  after the repurchase
order is received. Such  an arrangement is  subject to timely receipt  by A I  M
Fund  Services, Inc.,  the Funds' transfer  agent, of all  required documents in
good order. If such  documents are not received  within a reasonable time  after
the  order is placed,  the order is  subject to cancellation.  While there is no
charge imposed  by a  Fund or  by AIM  Distributors (other  than any  applicable
contingent  deferred  sales charge)  when  shares are  redeemed  or repurchased,
dealers may charge a fair service fee for handling the transaction.
    
 
   
The right of redemption may be suspended  or the date of payment postponed  when
(a)  trading on the  NYSE is restricted,  as determined by  applicable rules and
regulations of the SEC, (b) the NYSE is closed for other than customary  weekend
and holiday closings, (c) the SEC has by order permitted such suspension, or (d)
an  emergency as  determined by the  SEC exists making  disposition of portfolio
securities or  the  valuation  of  the  net assets  of  a  Fund  not  reasonably
practicable.
    
 
   
A  Fund's net asset  value is calculated  by dividing the  number of outstanding
shares into the net assets  of the Fund. Net assets  are the excess of a  Fund's
assets  over its liabilities. A more detailed description of how each Fund's net
asset value  is  calculated  appears  in  the  Prospectuses  under  the  heading
"Determination of Net Asset Value."

                                     TAXES
 
- --------------------------------------------------------------------------------
 
GENERAL
   
Each  Fund is treated as a separate corporation for federal income tax purposes.
To continue to qualify  for treatment as  a RIC under the  Code, each Fund  must
distribute  to  its shareholders  for  each taxable  year  at least  90%  of its
investment company  taxable  income  (consisting  generally  of  net  investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) ("Distribution  Requirement")  and must  meet  several  additional
requirements. These requirements include the following: (1) the Fund must derive
at  least 90% of  its gross income  each taxable year  from dividends, interest,
payments with  respect to  securities loans  and gains  from the  sale or  other
disposition  of  securities or  foreign currencies,  or other  income (including
gains from options, Futures  or Forward Contracts) derived  with respect to  its
business  of investing in securities or those currencies ("Income Requirement");
and (2) the Diversification Requirements.
    
 
Dividends and  other  distributions  declared  by a  Fund  in,  and  payable  to
shareholders  of record as  of a date  in, October, November  or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during  the following  January. Accordingly,  those distributions  will  be
taxed to shareholders for the year in which that December 31 falls.
 
   
If  Fund shares are sold at a loss after  being held for six months or less, the
loss will be treated  as long-term, instead of  short-term, capital loss to  the
extent  of any  capital gain distributions  received on  those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or other distribution, the shareholder will pay full price  for
the shares and receive some portion of the price back as a taxable distribution.
    
 
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent  it fails to distribute by the end of any calendar year substantially all
of its  ordinary income  for  that year  and capital  gain  net income  for  the
one-year period ending on October 31 of that year, plus certain other amounts.
 
FOREIGN TAXES
Dividends and interest received by each Fund, and gains realized thereby, may be
subject  to income, withholding or other  taxes imposed by foreign countries and
U.S. possessions  ("foreign taxes")  that would  reduce the  yield and/or  total
return  on its  securities. Tax  conventions between  certain countries  and the
United States may reduce or eliminate  foreign taxes, however, and many  foreign
countries  do not  impose taxes  on capital gains  in respect  of investments by
foreign investors. If more than 50% of the value of a Fund's total assets at the
close of its taxable  year consists of securities  of foreign corporations,  the
Fund  will be eligible to,  and may, file an  election with the Internal Revenue
Service that will enable its shareholders, in effect, to receive the benefit  of
the foreign tax credit with respect to any foreign taxes paid by it. Pursuant to
the  election,  the  Fund would  treat  those  taxes as  dividends  paid  to its
shareholders and each  shareholder would  be required  to (1)  include in  gross
income,  and treat as paid by him, his share of those taxes, (2) treat his share
of those taxes and of any dividend paid by the Fund that represents income  from
foreign  and U.S. possessions sources  as his own income  from those sources and
(3) either deduct the taxes deemed paid  by him in computing his taxable  income
or,  alternatively, use the foregoing information in calculating the foreign tax
credit against his federal income tax. Each Fund will report to its shareholders
shortly after each taxable  year their respective shares  of the Fund's  foreign
taxes  and income from sources within, and  taxes paid to, foreign countries and
U.S. possessions if it makes this election. Pursuant to the Taxpayer Relief  Act
of  1997 ("Tax Act"), individuals  who have no more  than $300 ($600 for married
persons filing jointly) of  creditable foreign taxes included  on Form 1099  and
all  of whose foreign source income is "qualified passive income" may elect each
year to be exempt from the  extremely complicated foreign tax credit  limitation
and  will be  able to  claim a  foreign tax  credit without  having to  file the
detailed Form 1116 that otherwise is required.
 
PASSIVE FOREIGN INVESTMENT COMPANIES
Each Fund may  invest in  the stock  of "passive  foreign investment  companies"
("PFICs").  A PFIC is a foreign corporation  -- other than a "controlled foreign
corporation" (I.E.,  a foreign  corporation  in which,  on  any day  during  its
taxable  year,  more than  50% of  the total  voting power  of all  voting stock
therein or the total value of  all stock therein is owned, directly,  indirectly

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
   
or  constructively,  by  "U.S.  shareholders,"  defined  as  U.S.  persons  that
individually own, directly, indirectly or  constructively, at least 10% of  that
voting  power) as to which a Fund  is a U.S. shareholder (effective with respect
to each  Fund for  its taxable  year beginning  November 1,  1998) --  that,  in
general,  meets either  of the following  tests: (1)  at least 75%  of its gross
income is passive or (2)  an average of at least  50% of its assets produce,  or
are  held for the production of,  passive income. Under certain circumstances, a
Fund will  be  subject  to federal  income  tax  on a  portion  of  any  "excess
distribution"  received on, or of  any gain from the  disposition of, stock of a
PFIC (collectively  "PFIC income"),  plus  interest thereon,  even if  the  Fund
distributes  the  PFIC income  as a  taxable dividend  to its  shareholders. The
balance of the  PFIC income will  be included in  the Fund's investment  company
taxable  income and,  accordingly, will not  be taxable  to it to  the extent it
distributes that income to its shareholders.
    
 
If a  Fund invests  in a  PFIC and  elects to  treat the  PFIC as  a  "qualified
electing  fund"  ("QEF"),  then  in  lieu  of  the  foregoing  tax  and interest
obligation, the Fund would be  required to include in  income each year its  pro
rata share of the QEF's ordinary earnings and net capital gain (I.E., the excess
of  net long-term capital gain  over net short-term capital  loss) -- which most
likely would have  to be  distributed by the  Fund to  satisfy the  Distribution
Requirement and avoid imposition of the Excise Tax -- even if those earnings and
gain  were not received by the  Fund from the QEF. In  most instances it will be
very difficult, if  not impossible,  to make  this election  because of  certain
requirements thereof.
 
   
Effective  for its taxable year beginning November  1, 1998, each Fund may elect
to "mark to market" its stock in any PFIC. "Marking-to-market," in this context,
means including in ordinary income each taxable year the excess, if any, of  the
fair  market value of the  stock over a Fund's adjusted  basis therein as of the
end of that  year. Pursuant  to the  election, a Fund  also will  be allowed  to
deduct  (as an ordinary, not capital, loss)  the excess, if any, of its adjusted
basis in  PFIC stock  over  the fair  market value  thereof  as of  the  taxable
year-end, but only to the extent of any net mark-to-market gains with respect to
that  stock included  in income by  the Fund  for prior taxable  years. A Fund's
adjusted basis in each PFIC's stock subject to the election will be adjusted  to
reflect  the  amounts  of  income  included  and  deductions  taken  thereunder.
Regulations proposed in  1992 provided a  similar election with  respect to  the
stock of certain PFICs.
    
 
NON-U.S. SHAREHOLDERS
Dividends  paid by a  Fund to a shareholder  who, as to the  United States, is a
nonresident alien individual, nonresident alien fiduciary of a trust or  estate,
foreign  corporation  or foreign  partnership ("foreign  shareholder") generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply, however, to a  dividend paid by a Fund to a  foreign
shareholder  that is "effectively connected with the  conduct of a U.S. trade or
business," in which case the  reporting and withholding requirements  applicable
to  domestic shareholders will  apply. A distribution  of net capital  gain by a
Fund to a foreign shareholder generally  will be subject to U.S. federal  income
tax  (at the rates applicable  to domestic persons) only  if the distribution is
"effectively connected"  or the  foreign shareholder  is treated  as a  resident
alien individual for federal income tax purposes.
 
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS
Each  Fund's  use  of  hedging  transactions,  such  as  selling  (writing)  and
purchasing options and  Futures and  entering into  Forward Contracts,  involves
complex  rules that will determine, for federal income tax purposes, the amount,
character and timing of recognition of the  gains and losses a Fund realizes  in
connection  therewith. Gains from the  disposition of foreign currencies (except
certain gains  that may  be  excluded by  future  regulations), and  gains  from
options,  Futures and Forward  Contracts derived by  a Fund with  respect to its
business of  investing in  securities  or foreign  currencies, will  qualify  as
permissible income under the Income Requirement.
 
   
Futures  and Forward  Contracts that  are subject  to section  1256 of  the Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts") and that are held by a Fund at the end of its taxable year generally
will be deemed to have been sold at that time at market value for federal income
tax  purposes. Sixty percent of any net  gain or loss recognized on these deemed
sales, and 60% of any net gain or loss realized from any actual sales of Section
1256 Contracts,  will be  treated as  long-term capital  gain or  loss, and  the
balance  will be treated  as short-term capital  gain or loss.  That 60% portion
will qualify for the  reduced maximum tax rates  on noncorporate taxpayers'  net
capital  gain  enacted by  the Tax  Act --  20%  (10% for  taxpayers in  the 15%
marginal tax bracket) for gain recognized  on capital assets held for more  than
18  months -- instead of  the 28% rate in  effect before that legislation, which
now applies to gain recognized on capital assets held for more than one year but
not more than 18 months.
    
 
Section 988 of the Code also may apply to gains and losses from transactions  in
foreign  currencies, foreign-currency-denominated  debt securities  and options,
Futures and Forward  Contracts on  foreign currencies ("Section  988" gains  and
losses).  Each Section  988 gain  or loss  generally is  computed separately and
treated as ordinary income or loss. In the case

                         AIM LATIN AMERICAN GROWTH FUND
of overlap  between sections  1256  and 988,  special provisions  determine  the
character  and timing of any income, gain  or loss. The Funds attempt to monitor
section 988 transactions to minimize any adverse tax impact.
 
If a Fund  has an  "appreciated financial  position" --  generally, an  interest
(including  an interest through an option,  Futures or Forward Contract or short
sale) with respect to any stock, debt instrument (other than "straight debt") or
partnership interest the fair market value  of which exceeds its adjusted  basis
- --  and enters into a  "constructive sale" of the  same or substantially similar
property, the Fund will be treated as  having made an actual sale thereof,  with
the  result  that gain  will be  recognized  at that  time. A  constructive sale
generally consists of a short sale, an offsetting notional principal contract or
Futures or Forward  Contract entered into  by a  Fund or a  related person  with
respect  to  the same  or substantially  similar property.  In addition,  if the
appreciated financial  position is  itself  a short  sale  or such  a  contract,
acquisition of the underlying property or substantially similar property will be
deemed a constructive sale.
 
The  foregoing  is a  general  and abbreviated  summary  of certain  federal tax
considerations affecting each Fund and its shareholders. Investors are urged  to
consult their own tax advisers for more detailed information and for information
regarding  any  foreign,  state  and  local  taxes  applicable  to distributions
received from the Funds.

- --------------------------------------------------------------------------------
 
   
AIM was organized in 1976, and  along with its subsidiaries, manages or  advises
approximately  90 investment  company portfolios  encompassing a  broad range of
investment objectives.  AIM  is a  direct,  wholly owned  subsidiary  of A  I  M
Management  Group  Inc.  ("AIM Management"),  a  holding company  that  has been
engaged in  the  financial  services  business  since  1976.  AIM  is  the  sole
shareholder   of  the  Fund's  principal   underwriter,  AIM  Distributors.  AIM
Management is an indirect wholly owned subsidiary of AMVESCAP PLC, 11 Devonshire
Square, London, EC2M  4YR, England.  AMVESCAP PLC  and its  subsidiaries are  an
independent  investment management group that has  a significant presence in the
institutional and retail segment of the investment management industry in  North
America and Europe, and a growing presence in Asia.
    
 
CUSTODIAN
State  Street  Bank and  Trust Company  ("State  Street"), 225  Franklin Street,
Boston, MA  02110, acts  as custodian  of each  Fund's assets.  State Street  is
authorized  to  establish  and  has  established  separate  accounts  in foreign
currencies and to cause securities of each Fund to be held in separate  accounts
outside the United States in the custody of non-U.S. banks.
 
INDEPENDENT ACCOUNTANTS
   
The  Funds'  independent accountants  are                                      .
                        conducts an annual  audit of each  Fund, assists in  the
preparation of the Funds' federal and state income tax returns and consults with
the  Company and the Funds as to  matters of accounting, regulatory filings, and
federal and state income taxation.
    
 
   
The audited financial statements  of the Company included  in this Statement  of
Additional Information have been examined by                         , as stated
in their opinion appearing herein and are included in reliance upon such opinion
given upon the authority of that firm as experts in accounting and auditing.
    
 
   
SHAREHOLDER LIABILITY
    
   
Under  Delaware law,  the shareholders of  the Trust enjoy  the same limitations
extended to shareholders of private, for-profit corporations. There is a  remote
possibility, however, that under certain circumstances shareholders of the Trust
may  be held personally  liable for the Trust's  obligations. However, the Trust
Agreement disclaims shareholder liability for  acts or obligations of the  Trust
and  requires  that  notice  of  such disclaimer  be  given  in  each agreement,
obligation or instrument entered into or executed by the Trust or a trustee. The
Trust Agreement provides  for indemnification  from the Trust  property for  all
losses  and expenses of  any shareholder held personally  liable for the Trust's
obligations. Thus, the risk of a shareholder incurring financial loss on account
of such liability is limited to circumstances in which the Trust itself would be
unable to meet  its obligations and  where the other  party was held  not to  be
bound by the disclaimer.

Where      P              =      a hypothetical initial payment of $1,000.
           T              =      average annual  total return  (assuming  the applicable  maximum sales  load  is
                                 deducted at the beginning of the 5, or 10 year periods).
           n              =      number of years.
           ERV            =      ending redeemable value of a hypothetical $1,000 payment at the end of the 1, 5,

OTHER INFORMATION  REGARDING STANDARD  TOTAL AND  CUMULATIVE TOTAL  RETURNS  FOR
DEVELOPING MARKETS FUND
    
   
The  standard total and cumulative total  return data of Developing Markets Fund
are based on the performance of the Predecessor Fund as a closed-end  investment
company.  The  standard  total return  data,  however, have  been  recomputed to
reflect the deduction of the current maximum  sales charge of 4.75% for Class  A
shares,  which  went into  effect  on November  1,  1997. Future  performance of
Developing Markets Fund will  be effected by  expenses that it  will incur as  a
series of an open-end investment company.

to  revision  and  has not  been  independently  verified by  the  Funds  or AIM
Distributors.  Advertising  for  the  Funds  may  from  time  to  time   include
discussions  of general economic conditions  and interest rates. Advertising for
the Funds may also  include reference to the  use of those Funds  as part of  an
individual's  overall retirement  investment program.  From time  to time, sales
literature and/or  advertisements for  any of  the Funds  may disclose  (i)  the
largest  holdings in  the Fund's portfolio,  (ii) certain  selling group members
and/or (iii) certain institutional shareholders.
    
 
   
From time to time, the Funds' sales literature and/or advertisements may discuss
generic topics pertaining to the mutual fund industry. This includes, but is not
limited to,  literature  addressing  general  information  about  mutual  funds,
variable   annuities,  dollar-cost  averaging,  stocks,  bonds,  money  markets,
certificates  of  deposit,  retirement,  retirement  plans,  asset   allocation,
tax-free investing, college planning, and inflation.
    
 
   
Although  performance data may be useful to prospective investors when comparing
a Fund's performance with other funds and other potential investments, investors
should note  that  the  methods  of computing  performance  of  other  potential
investments are not necessarily comparable to the methods employed by a Fund.

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by  various entities from "Aaa"  to "C." Investment grade  ratings are the first
four categories:
 
        Aaa -- Bonds which are rated Aaa  are judged to be of the best  quality.
    They carry the smallest degree of investment risk and are generally referred
    to  as "gilt  edged." Interest payments  are protected  by a large  or by an
    exceptionally stable  margin  and principal  is  secure. While  the  various
    protective  elements are likely to change, such changes as can be visualized
    are most  unlikely  to impair  the  fundamentally strong  position  of  such
    issues.
 
        Aa  -- Bonds which are rated Aa are  judged to be of high quality by all
    standards. Together  with the  Aaa group  they comprise  what are  generally
    known  as high grade bonds. They are  rated lower than the best bond because
    margins of  protection  may  not  be  as  large  as  in  Aaa  securities  or
    fluctuation  of protective elements may be of greater amplitude or there may
    be other  elements present  which make  the long-term  risk appear  somewhat
    larger than the Aaa securities.
 
        A  --  Bonds  which  are  rated  A  possess  many  favorable  investment
    attributes and  are  to  be considered  as  upper-medium-grade  obligations.
    Factors  giving security to principal  and interest are considered adequate,
    but elements may  be present  which suggest a  susceptibility to  impairment
    some time in the future.
 
        Baa  --  Bonds  which  are  rated  Baa  are  considered  as medium-grade
    obligations, (i.e., they are neither  highly protected nor poorly  secured).
    Interest payments and principal security appear adequate for the present but
    certain  protective  elements may  be lacking  or may  be characteristically
    unreliable over  any  great length  of  time. Such  bonds  lack  outstanding
    investment  characteristics and in fact  have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative  elements;
    their  future cannot be considered as  well-assured. Often the protection of
    interest and principal payments may be  very moderate, and thereby not  well
    safeguarded  during other good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B --  Bonds which  are rated  B generally  lack characteristics  of  the
    desirable  investment. Assurance  of interest  and principal  payments or of
    maintenance of other terms of the contract over any long period of time  may
    be small.
 
        Caa  -- Bonds which are rated Caa  are of poor standing. Such issues may
    be in default or  there may be  present elements of  danger with respect  to
    principal or interest.
 
        Ca  --  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are  rated C are the lowest  rated class of bonds,  and
    issues  so rated can be regarded as  having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has  been
suspended  or withdrawn, it may  be for reasons unrelated  to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2. The issue or issuer  belongs to a group  of securities or companies  that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.

                           AIM EMERGING MARKETS FUND
                         AIM LATIN AMERICAN GROWTH FUND
 
Suspension  or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data  to permit  a judgment  to be  formed; if  a bond  is
called for redemption; or for other reasons.
 
Note:  Moody's applies numerical  modifiers, 1, 2  and 3 in  each generic rating
classification from Aa to Caa. The  modifier 1 indicates that the Company  ranks
in  the higher end  of its generic  rating category; the  modifier 2 indicates a
mid-range ranking; and the  modifier 3 indicates that  the Company ranks in  the
lower end of its generic rating category.
 
    STANDARD  & POOR'S, a  division of The  McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various  entities in categories ranging from  "AAA"
to  "D"  according  to quality.  Investment  grade  ratings are  the  first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA  --  An  obligation  rated  "AA"  differs  from  the  highest   rated
    obligations  only  in a  small degree.  The obligor's  capacity to  meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB  --  An   obligation  rated  "BBB"   exhibits  adequate   protection
    parameters.  However, adverse economic  conditions or changing circumstances
    are more likely to lead  to a weakened capacity of  the obligor to meet  its
    financial commitment on the obligation.
 
        BB,  B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and "C"
    are  regarded  as  having  significant  speculative  characteristics.   "BB"
    indicates  the least degree  of speculation and "C"  the highest. While such
    obligations will likely  have some quality  and protective  characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB  -- An  obligation rated "BB"  is less vulnerable  to nonpayment than
    other speculative issues. However, it  faces major ongoing uncertainties  or
    exposure  to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate  capacity to meet its financial  commitment
    on the obligation.
 
        B  --  An obligation  rated "B"  is more  vulnerable to  nonpayment than
    obligations rated "BB," but the obligor  currently has the capacity to  meet
    its  financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to  nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for  the obligor to meet its financial  commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to  have the  capacity to meet  its financial  commitment on  the
    obligation.
 
        CC  --  An  obligation  rated "CC"  is  currently  highly  vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a  bankruptcy
    petition  has been filed or  similar action has been  taken, but payments on
    this obligation are being continued.
 
        D --  An obligation  rated "D"  is in  payment default.  The "D"  rating
    category is used when payments on an obligation are not made on the date due
    even  if the  applicable grace period  has not expired,  unless S&P believes
    that such payments  will be made  during such grace  period. The "D"  rating
    also  will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by  the
addition  of a  plus or minus  sign to  show relative standing  within the major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient  information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs  the  designation  "Prime-1" to  indicate  commercial  paper
having  a superior ability for repayment  of senior short-term debt obligations.
Prime-1 repayment  ability will  often be  evidenced by  many of  the  following
characteristics:  leading market positions  in well-established industries; high
rates of return  on funds employed;  conservative capitalization structure  with
moderate  reliance on debt and ample asset protection; broad margins in earnings
coverage of

                          AIM DEVELOPING MARKETS FUND

                         AIM LATIN AMERICAN GROWTH FUND
fixed financial charges and high internal cash generation; and  well-established
access  to  a  range  of  financial markets  and  assured  sources  of alternate
liquidity. Issues rated Prime-2  have a strong ability  for repayment of  senior
short-term  debt obligations.  This normally  will be  evidenced by  many of the
characteristics cited above but to a lesser degree. Earnings trends and coverage
ratios,  while  sound,  may  be   more  subject  to  variation.   Capitalization
characteristics,  while  still appropriate,  may  be more  affected  by external
conditions. Ample alternate liquidity is maintained.
 
    S&P ratings of commercial paper  are graded into several categories  ranging
from  "A1" for the highest quality obligations  to "D" for the lowest. Issues in
the "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate  the
relative  degree  of safety.  A-1 --  This highest  category indicates  that the
degree of safety regarding timely payment is strong. Those issues determined  to
possess extremely strong safety characteristics will be denoted with a plus sign
(+)  designation.  A-2  -- Capacity  for  timely  payments on  issues  with this
designation is satisfactory; however,  the relative degree of  safety is not  as
high as for issues designated "A-1."

                                  INTRODUCTION
 
- --------------------------------------------------------------------------------
 
This  Statement of Additional Information relates to the Advisor Class shares of
AIM Global  Financial  Services Fund  ("Financial  Services Fund"),  AIM  Global
Infrastructure   Fund  ("Infrastructure   Fund"),  AIM   Global  Resources  Fund
("Resources Fund"), AIM  Global Consumer Products  and Services Fund  ("Consumer
Products  and Services Fund"), AIM Global  Health Care Fund ("Health Care Fund")
and AIM  Global Telecommunications  Fund  ("Telecommunications Fund")  (each,  a
"Fund"  or "Theme Fund,"  and collectively, the "Funds"  or "Theme Funds"). Each
Fund is a diversified series of AIM Investment Funds (the "Trust"), a registered
open-end management investment company organized  as a Delaware business  trust.
The  Financial Services Fund,  Infrastructure Fund, Resources  Fund and Consumer
Products and Services Fund (each a "Feeder Fund," and, collectively the  "Feeder
Funds,")  invest all of their investable assets in the Global Financial Services
Portfolio, Global  Infrastructure  Portfolio,  Global  Resources  Portfolio  and
Global  Consumer  Products and  Services  Portfolio (each,  a  "Portfolio," and,
collectively, the "Portfolios"), respectively.
 
A  I  M  Advisors,  Inc.  ("AIM")  serves  as  the  investment  manager  of  and
administrator  for, and  INVESCO (NY),  Inc. (the  "Sub-adviser") serves  as the
investment sub-adviser  of  and  sub-administrator for  the  Health  Care  Fund,
Telecommunications  Fund  and  the  Portfolios (each  a  "Theme  Portfolio," and
collectively the "Theme Portfolios"). AIM and the Sub-adviser also serve as  the
administrator and sub-administrator, respectively, for each Feeder Fund.
 
The  Trust is  a series  mutual fund.  The rules  and regulations  of the United
States Securities and Exchange Commission  (the "SEC") require all mutual  funds
to  furnish prospective investors certain  information concerning the activities
of the  fund being  considered for  investment. This  information for  Financial
Services  Fund  is  included  in  a  Prospectus  dated  September  8,  1998, for
Infrastructure Fund  is included  in a  separate Prospectus  dated September  8,
1998, for Resources Fund is included in a separate Prospectus dated September 8,
1998,  for  Consumer  Products  and  Services Fund  is  included  in  a separate
Prospectus dated  September 8,  1998, for  Health  Care Fund  is included  in  a
separate  Prospectus dated September 8, 1998, and for Telecommunications Fund is

the  Prospectuses and this  Statement of Additional  Information may be obtained
without charge by writing the principal distributor of the Funds' shares, A I  M
Distributors,  Inc. ("AIM Distributors"), P.O.  Box 4739, Houston, TX 77210-4739
or by calling (800)  347-4246. Investors must receive  a Prospectus before  they
invest.
 
This  Statement  of Additional  Information is  intended to  furnish prospective
investors  with  additional  information  concerning  the  Funds.  Some  of  the
information  required to be in this  Statement of Additional Information is also
included in the Prospectus, and, in order to avoid repetition, reference will be
made to  sections  of the  Prospectus.  Additionally, the  Prospectus  and  this
Statement  of Additional Information  omit certain information  contained in the
Registration Statement filed with the SEC. Copies of the Registration Statement,
including items omitted  from the  Prospectus and this  Statement of  Additional
Information, may be obtained from the SEC by paying the charges prescribed under
its rules and regulations.
 
                      GENERAL INFORMATION ABOUT THE FUNDS
 
THE TRUST AND ITS SHARES
The  Trust previously operated under the name G.T. Investment Funds, Inc., which
was organized  as a  Maryland corporation  on October  29, 1987.  The Trust  was
reorganized on September 4, 1998 as a Delaware business trust, and is registered
with the SEC as a diversified open-end series management investment company. The
Trust  currently consists of thirteen separate portfolios: each of the six Theme
Funds, AIM  Global Government  Income Fund,  AIM Global  High Income  Fund,  AIM
Strategic  Income Fund, AIM Global Growth  and Income Fund, AIM Emerging Markets
Fund, AIM Developing Markets Fund, and  AIM Latin American Growth Fund. Each  of
these  funds has  three separate  classes: Class  A, Class  B and  Advisor Class
shares. All  historical  financial  and  other  information  contained  in  this
Statement  of Additional Information for periods  prior to September 4, 1998, is
that of the series  G.T. Investment Funds, Inc.  (renamed AIM Investment  Funds,
Inc.).
 
This  Statement of  Additional Information relates  solely to  the Advisor Class
shares of the Funds.
 
                   Statement of Additional Information Page 3
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
The term "majority of the outstanding shares" of the Trust, of a particular Fund
or of a particular class of a  Fund means, respectively, the vote of the  lesser
of  (a) 67% or more of the shares of  the Trust, such Fund or such class present
at a meeting of the Trust's shareholders, if the holders of more than 50% of the
outstanding shares  of  the  Trust, such  Fund  or  such class  are  present  or
represented  by proxy,  or (b) more  than 50%  of the outstanding  shares of the
Trust, such Fund or such class.
 
Class A, Class B  and Advisor Class  shares of each Fund  have equal rights  and
privileges.  Each  share of  a  particular class  is  entitled to  one  vote, to
participate equally in dividends and distributions declared by the Trust's Board
of Trustees with respect to the class of such Fund and, upon liquidation of  the
Fund,  to participate proportionately in the net assets of the Fund allocable to
such class remaining after satisfaction  of outstanding liabilities of the  Fund
allocable  to such class.  Fund shares are fully  paid, non-assessable and fully
transferable when issued and have no preemptive rights and have such  conversion
and  exchange  rights as  set  forth in  the  Prospectus and  this  Statement of
Additional Information. Fractional shares have proportionately the same  rights,
including voting rights, as are provided for a full share.
 
Shareholders  of the Funds  do not have cumulative  voting rights, and therefore
the holders of  more than  50% of  the outstanding  shares of  all Funds  voting
together  for election of trustees may elect all  of the members of the Board of
Trustees of the  Trust. In such  event, the remaining  holders cannot elect  any
trustees of the Trust.

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES
The  investment objective of  each Feeder Fund is  long-term capital growth. The
investment objective  of the  Health Care  Fund and  Telecommunications Fund  is
long-term capital appreciation and long-term growth of capital, respectively.
 
Each  Feeder Fund seeks to achieve its  investment objective by investing all of
its investable assets in a Portfolio, each  of which is a subtrust (a  "series")
of Global Investment Portfolio (an open-end management investment company), with
an  investment objective that  is identical to that  of its corresponding Feeder
Fund. Whenever the phrase "all of a Fund's investable assets" is used herein and
in the Prospectus, it means that the only investment securities held by a Feeder
Fund will be  its interest  in its corresponding  Portfolio. A  Feeder Fund  may
withdraw its investment in its corresponding Portfolio at any time, if the Board
of Trustees of the Trust determines that it is in the best interests of the Fund
and  its shareholders to do so. Upon any such withdrawal, a Feeder Fund's assets
would  be  invested  in   accordance  with  the   investment  policies  of   its
corresponding Portfolio described below and in the Prospectus.
 
SELECTION OF EQUITY INVESTMENTS
With  respect to  the Resources Portfolio,  the Sub-adviser  has identified four
areas that  it  expects  will create  investment  opportunities:  (i)  improving
supply/demand  fundamentals, which may  result in higher  commodity prices; (ii)
privatization of state-owned natural resource businesses; (iii) management which
can improve production efficiencies without correspondingly increasing commodity
prices; and (iv) service companies  with emerging technologies that can  enhance
productivity  or reduce production costs. Of  course, there is no certainty that
these factors will produce the anticipated results.
 
With respect to the Telecommunications Fund, the Sub-adviser has identified four
areas that it expects will create investment opportunities: (i) deregulation  of
companies  in  the industry,  which will  allow  competition to  promote greater
efficiencies; (ii) privatization  of state-owned telecommunications  businesses;
(iii) development of infrastructure in underdeveloped countries and upgrading of
services  in other countries;  and (iv) emerging  technologies that will enhance
productivity and reduce  costs in  the telecommunications  industry. Of  course,
there is no certainty that these factors will produce the anticipated results.
 
There  may be times when, in the  opinion of the Sub-adviser, prevailing market,
economic or political conditions  warrant reducing the  proportion of the  Theme
Portfolios'  assets invested in equity  securities and increasing the proportion
held in cash (U.S. dollars, foreign currencies or multinational currency  units)
or  invested in debt securities or  high quality money market instruments issued
by corporations or the U.S.,  or a foreign government.  A portion of each  Theme
Portfolio's  assets  normally  will  be  held  in  cash  (U.S.  dollars, foreign
currencies  or   multinational   currency   units)  or   invested   in   foreign
 
                   Statement of Additional Information Page 4
<PAGE>
                             AIM GLOBAL THEME FUNDS
or domestic high quality money market instruments pending investment of proceeds
from  new sales of  fund shares to  provide for ongoing  expenses and to satisfy
redemptions.
 
For  each  Theme  Portfolio's  investment  purposes,  an  issuer  is   typically
considered  as located in a particular country  if it (a) is organized under the
laws of or has  its principal office  in a particular  country, or (b)  normally
derives  50%  or more  of  its total  revenues  from business  in  that country,
provided that, in the Sub-adviser's view, the value of such issuer's  securities
will  tend  to  reflect such  country's  development  to a  greater  extent than
developments elsewhere.  However,  these  are  not  absolute  requirements,  and
certain  companies incorporated  in a particular  country and  considered by the
Sub-adviser  to  be  located  in  that  country  may  have  substantial  foreign
operations  or subsidiaries and/or export sales  exceeding in size the assets or
sales in that country.
 
In  certain  countries,  governmental  restrictions  and  other  limitations  on
investment  may affect a Theme Portfolio's  ability to invest in such countries.
In addition,  in  some instances  only  special  classes of  securities  may  be
purchased by foreigners and the market prices, liquidity and rights with respect
to  those securities may vary from shares owned by nationals. The Sub-adviser is
not aware at this time  of the existence of  any investment or exchange  control
regulations  which  might  substantially  impair  the  operations  of  the Theme
Portfolios as  described in  the  Prospectus and  this Statement  of  Additional
Information.  Restrictions may  in the future,  however, make  it undesirable to
invest in  certain  countries.  None  of the  Theme  Portfolios  has  a  present
intention of making any significant investment in any country or stock market in
which  the Sub-adviser considers the political or economic situation to threaten
a Theme  Portfolio with  substantial or  total loss  of its  investment in  such
country or market.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
Each  Theme  Portfolio  may invest  in  the securities  of  investment companies
(including investment vehicles or  companies advised by  the Sub-adviser or  its
affiliates ("Affiliated Funds")) within the limits of the Investment Company Act
of  1940, as amended (the "1940 Act"). These limitations currently provide that,
in general,  a Theme  Portfolio may  purchase shares  of an  investment  company
unless (a) such a purchase would cause a Theme Portfolio to own in the aggregate
more  than 3% of the total outstanding voting stock of the investment company or
(b) such a purchase would cause the Theme Portfolio to have more than 5% of  its
assets  invested  in the  investment  company or  more  than 10%  of  its assets
invested in  an  aggregate  of  all such  investment  companies.  The  foregoing
restrictions  do not  apply to  the investment  of the  Financial Services Fund,
Infrastructure Fund, Resources Fund and  Consumer Products and Services Fund  in
their  corresponding Portfolios.  Investment in  closed-end investment companies
may involve  the  payment  of  substantial premiums  above  the  value  of  such
companies'  portfolio securities. Each Theme Portfolio does not intend to invest
in such investment  companies unless, in  the judgment of  the Sub-adviser,  the
potential  benefits of  such investments justify  the payment  of any applicable
premiums. The return on such securities will be reduced by operating expenses of
such  companies,  including  payments  to  the  investment  managers  of   those
investment  companies.  With respect  to  investments in  Affiliated  Funds, the
Sub-adviser waives its advisory fee  to the extent that  such fees are based  on
assets of a Theme Portfolio invested in Affiliated Funds.
 
DEPOSITARY RECEIPTS
A Theme Portfolio may hold securities of foreign issuers in the form of American
Depositary  Receipts  ("ADRs"),  American  Depositary  Shares  ("ADSs"),  Global
Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs") or  other
securities  convertible  into  securities  of  eligible  foreign  issuers. These
securities may  not necessarily  be  denominated in  the  same currency  as  the
securities  for which they may be exchanged.  ADRs and ADSs are typically issued
by an  American bank  or  trust company  and  evidence ownership  of  underlying
securities  issued by a foreign corporation.  EDRs, which are sometimes referred
to as Continental Depositary Receipts  ("CDRs"), are issued in Europe  typically
by foreign banks and trust companies and evidence ownership of either foreign or
domestic  securities.  GDRs are  similar to  EDRs  and are  designed for  use in
several international financial markets. Generally, ADRs and ADSs in  registered
form are designed for use in U.S. securities markets and EDRs in bearer form are
designed  for use  in European  securities markets.  For purposes  of each Theme
Portfolio's investment policies, a Theme Portfolio's investments in ADRs,  ADSs,
GDRs  and  EDRs  will be  deemed  to  be investments  in  the  equity securities
representing securities of foreign issuers into which they may be converted.
 
ADR facilities may be established as either "unsponsored" or "sponsored."  While
ADRs  issued under these two  types of facilities are  in some respects similar,
there are distinctions between  them relating to the  rights and obligations  of
ADR holders and the practices of market participants. A depository may establish
an  unsponsored  facility  without  participation by  (or  even  necessarily the
acquiescence of) the issuer of the deposited securities, although typically  the
depository  requests a  letter of  non-objection from  such issuer  prior to the
establishment of the facility.  Holders of unsponsored  ADRs generally bear  all
the  costs  of such  facilities. The  depository usually  charges fees  upon the
deposit and withdrawal of the deposited securities, the conversion of  dividends
into   U.S.  dollars,  the  disposition   of  non-cash  distributions,  and  the
 
                   Statement of Additional Information Page 5
<PAGE>
                             AIM GLOBAL THEME FUNDS
performance of  other  services.  The  depository  of  an  unsponsored  facility
frequently  is  under  no obligation  to  distribute  shareholder communications
received from the issuer of the  deposited securities or to pass-through  voting
rights  to ADR  holders in  respect of  the deposited  securities. Sponsored ADR
facilities are created in generally  the same manner as unsponsored  facilities,
except  that  the  issuer of  the  deposited  securities enters  into  a deposit
agreement with the  depository. The deposit  agreement sets out  the rights  and
responsibilities  of  the  issuer,  the depository  and  the  ADR  holders. With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository), although ADR holders continue to bear certain other costs (such  as
deposit  and withdrawal fees).  Under the terms  of most sponsored arrangements,
depositories agree  to distribute  notices of  shareholder meetings  and  voting
instructions, and to provide shareholder communications and other information to
the  ADR holders at the  request of the issuer  of the deposited securities. The
Theme Portfolios may invest in both sponsored and unsponsored ADRs.
 
WARRANTS OR RIGHTS
Warrants or rights may be acquired by a Theme Portfolio in connection with other
securities or  separately and  provide the  Theme Portfolio  with the  right  to
purchase at a later date other securities of the issuer.
 
LENDING OF PORTFOLIO SECURITIES
For  the purpose of  realizing additional income, each  Theme Portfolio may make
secured loans of its securities holdings amounting  to not more than 30% of  its
total  assets.  Securities loans  are  made to  broker/dealers  or institutional
investors pursuant  to  agreements  requiring that  the  loans  be  continuously
secured by collateral at least equal at all times to the value of the securities
lent  plus any accrued interest, "marked to  market" on a daily basis. The Theme
Portfolios may pay  reasonable administrative and  custodial fees in  connection
with  the loans of their securities. While the securities loan is outstanding, a
Theme Portfolio  will continue  to receive  the equivalent  of the  interest  or
dividends  paid by  the issuer  on the  securities, as  well as  interest on the
investment of the collateral or a fee from the borrower. A Theme Portfolio  will
have  a right  to call  each loan  and obtain  the securities  within the stated
settlement period. A  Theme Portfolio  will not have  the right  to vote  equity
securities  while they are being lent, but it may call in a loan in anticipation
of any  important  vote.  Loans  will  only be  made  to  firms  deemed  by  the
Sub-adviser  to be of good standing and will not be made unless, in the judgment
of the Sub-adviser, the consideration to be earned from such loans would justify
the risk.
 
MONEY MARKET INSTRUMENTS
Money market instruments in which the  Theme Portfolios may invest include  U.S.
government   securities,  high-grade  commercial  paper,  bank  certificates  of
deposit, bankers' acceptances and  repurchase agreements related  to any of  the
foregoing. "High-grade commercial paper" refers to commercial paper rated A-1 by
Standard  & Poor's,  a division  of The McGraw-Hill  Companies, Inc.,  or P-1 by
Moody's Investors Services, Inc. or, if not rated, determined by the Sub-adviser
to be of comparable quality.
 
COMMERCIAL BANK OBLIGATIONS
For the purposes of each Theme  Portfolio's investment policies with respect  to
bank  obligations, obligations of foreign branches  of U.S. banks and of foreign
banks are obligations of the issuing bank and may be general obligations of  the
parent  bank.  Such obligations  may,  however, be  limited  by the  terms  of a
specific obligation  and  by  government  regulation.  As  with  investments  in
non-U.S.  securities  in  general,  investments in  the  obligations  of foreign
branches of U.S. banks and of foreign banks may subject each Theme Portfolio  to
investment  risks that are different in  some respects from those of investments
in obligations of  U.S. issuers.  Although each Theme  Portfolio will  typically
acquire  obligations issued and supported by the credit of U.S. or foreign banks
having total assets  at the  time of  purchase of $1  billion or  more, this  $1
billion  figure  is  not  an  investment policy  or  restriction  of  each Theme
Portfolio. For  the purposes  of  calculation with  respect  to the  $1  billion
figure,  the assets of a bank  will be deemed to include  the assets of its U.S.
and non-U.S. branches.
 
REPURCHASE AGREEMENTS
A repurchase agreement is a transaction  in which a Theme Portfolio purchases  a
security  from a bank or recognized securities dealer and simultaneously commits
to resell that security to the bank or dealer at an agreed-upon price, date, and
market rate  of  interest  unrelated to  the  coupon  rate or  maturity  of  the
purchased  security.  Although  repurchase agreements  carry  certain  risks not
associated with direct investments in securities, including possible decline  in
the  market value of the underlying securities and delays and costs to the Theme
Portfolio if the other party to  the repurchase agreement becomes bankrupt,  the
Theme  Portfolios intend to enter into repurchase agreements only with banks and
dealers  believed  by  the  Sub-adviser  to  present  minimal  credit  risks  in
accordance  with guidelines established by the  Trust's or the Portfolios' Board
of Trustees,  as  applicable.  The  Sub-adviser  will  review  and  monitor  the
creditworthiness  of  such  institutions under  the  applicable  Board's general
supervision.
 
                   Statement of Additional Information Page 6
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
Each Theme Portfolio will invest only in repurchase agreements collateralized at
all times in  an amount  at least  equal to  the repurchase  price plus  accrued
interest.  To the extent that the proceeds from any sale of such collateral upon
a default in the obligation to repurchase were less than the repurchase price, a
Theme Portfolio would suffer a loss. If the financial institution which is party
to the  repurchase  agreement  petitions for  bankruptcy  or  otherwise  becomes
subject   to  bankruptcy  or   other  liquidation  proceedings,   there  may  be
restrictions on a Theme Portfolio's ability  to sell the collateral and a  Theme
Portfolio  could suffer a loss. However,  with respect to financial institutions
whose bankruptcy or liquidation proceedings  are subject to the U.S.  Bankruptcy
Code,  each Theme  Portfolio intends to  comply with provisions  under such Code
that would allow the immediate resale  of such collateral. Each Theme  Portfolio
will  not enter into a  repurchase agreement with a  maturity of more than seven
days if, as a result, more than 15%  of the value of its net assets (except  for
Health  Care Fund,  more than  10% of the  value of  its total  assets) would be
invested in such repurchase agreements and other illiquid investments.
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
Each Theme Portfolio's borrowings will not  exceed 33 1/3% of its total  assets,
i.e.,  the Theme Portfolio's total assets at  all times will equal at least 300%
of the amount of outstanding borrowings. If market fluctuations in the value  of
a  Theme Portfolio's securities holdings  or other factors cause  the ratio of a
Theme Portfolio's total  assets to  outstanding borrowings to  fall below  300%,
within  three days  (excluding Sundays  and holidays)  of such  event that Theme
Portfolio may be required to sell portfolio securities to restore the 300% asset
coverage, even  though  from  an  investment  standpoint  such  sales  might  be
disadvantageous.  Each Theme  Portfolio may  also borrow up  to 5%  of its total
assets for temporary or emergency purposes  other than to meet redemptions.  Any
borrowing by a Theme Portfolio may cause greater fluctuation in the value of its
shares than would be the case if that Theme Portfolio did not borrow.
 
Each  Theme  Portfolio's  fundamental investment  limitations  permit  the Theme
Portfolio to borrow money for leveraging purposes. However, each Theme Portfolio
(except the  Health Care  Fund)  is currently  prohibited,  pursuant to  a  non-
fundamental  investment  policy,  from  borrowing  money  in  order  to purchase
securities. Nevertheless,  this policy  may  be changed  in  the future  by  the
Trust's  or  the  Portfolios'  Board  of Trustees,  as  applicable.  If  a Theme
Portfolio employs  leverage  in the  future,  it  would be  subject  to  certain
additional  risks. Use of leverage creates  an opportunity for greater growth of
capital but would exaggerate any increases  or decreases in the net asset  value
of  the Financial Services  Fund, Infrastructure Fund,  Resources Fund, Consumer
Products and Services Fund or  a Theme Portfolio. When  the income and gains  on
securities  purchased with the  proceeds of borrowings exceed  the costs of such
borrowings, a  Theme Portfolio's  earnings  or a  Fund's  net asset  value  will
increase faster than otherwise would be the case; conversely, if such income and
gains  fail to exceed such  costs, a Theme Portfolio's  earnings or a Fund's net
asset value would decline faster than would otherwise be the case.
 
Each Theme Portfolio  may enter  into reverse repurchase  agreements. A  reverse
repurchase agreement is a borrowing transaction in which the Portfolio transfers
possession  of a security  to another party  such as a  bank or broker/dealer in
return for cash,  and agrees  to repurchase  the security  in the  future at  an
agreed  upon price, which  includes an interest  component. Each Theme Portfolio
may also engage  in "roll"  borrowing transactions,  which involve  the sale  of
Government  National  Mortgage  Association  certificates  or  other  securities
together with a commitment (for which the Theme Portfolio may receive a fee)  to
purchase  similar, but  not identical, securities  at a future  date. Each Theme
Portfolio will  segregate with  a custodian,  cash or  liquid securities  in  an
amount sufficient to cover its obligations under "roll" transactions and reverse
repurchase  agreements  with  broker/dealers.  No  segregation  is  required for
reverse repurchase agreements with banks.
 
SHORT SALES
Each Theme Portfolio  may make  short sales  of securities.  A short  sale is  a
transaction in which a Theme Portfolio sells a security in anticipation that the
market  price of that  security will decline.  A Theme Portfolio  may make short
sales (i) as a form of hedging to offset potential declines in long positions in
securities it owns, or anticipates acquiring, or in similar securities, and (ii)
in order to maintain flexibility in its securities holdings.
 
When a Theme Portfolio makes a short sale of a security it does not own, it must
borrow the security  sold short  and deliver it  to the  broker/dealer or  other
intermediary  through which it made the short sale. The Theme Portfolio may have
to pay a fee to borrow particular securities and will often be obligated to  pay
over any payments received on such borrowed securities.
 
A  Theme  Portfolio's  obligation  to replace  the  borrowed  security  when the
borrowing is called or expires will be secured by collateral deposited with  the
intermediary.  The Theme Portfolio  will also be  required to deposit collateral
with its custodian to the  extent, if any, necessary so  that the value of  both
collateral  deposits in the aggregate is at all  times equal to at least 100% of
the current market value of the  security sold short. Depending on  arrangements
made with the

intermediary  from  which  it borrowed  the  security regarding  payment  of any
amounts received by that Theme Portfolio on such security, a Theme Portfolio may
not receive any payments (including  interest) on its collateral deposited  with
such intermediary.
 
If  the price of the security sold short increases between the time of the short
sale and the time a Theme  Portfolio replaces the borrowed security, that  Theme
Portfolio  will  incur a  loss;  conversely, if  the  price declines,  the Theme
Portfolio will  realize  a  gain. Any  gain  will  be decreased,  and  any  loss
increased,  by the transaction costs associated with the transaction. Although a
Theme Portfolio's gain is  limited by the  price at which  it sold the  security
short, its potential loss theoretically is unlimited.
 
No  Theme Portfolio will make a short sale if, after giving effect to such sale,
the market value of the  securities sold short exceeds 25%  of the value of  its
total assets or the Theme Portfolio's aggregate short sales of the securities of
any one issuer exceed the lesser of 2% of the Theme Portfolio's net assets or 2%
of  the securities of any  class of the issuer.  Moreover, a Theme Portfolio may
engage in  short sales  only with  respect to  securities listed  on a  national
securities  exchange. A Theme  Portfolio may make short  sales "against the box"
without respect to such limitations. In this type of short sale, at the time  of
the  sale the  Theme Portfolio owns  the security it  has sold short  or has the
immediate and unconditional right to acquire at no additional cost the identical
security.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The use of options, futures  contracts and forward currency contracts  ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1)  Successful  use  of  most of  these  instruments  depends  upon the
    Sub-adviser's ability to  predict movements  of the  overall securities  and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-adviser is experienced in
    the  use of these instruments, there can be no assurance that any particular
    strategy adopted will succeed.
 
        (2) There  might  be  imperfect correlation,  or  even  no  correlation,
    between  price  movements  of  an  instrument  and  price  movements  of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge  increased by less  than the  decline in value  of the  hedged
    investment,  the  hedge  would  not  be fully  successful.  Such  a  lack of
    correlation might  occur  due to  factors  unrelated  to the  value  of  the
    investments  being hedged,  such as  speculative or  other pressures  on the
    markets in  which the  hedging instrument  is traded.  The effectiveness  of
    hedges  using hedging  instruments on indices  will depend on  the degree of
    correlation between price movements in the index and price movements in  the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or  partially offsetting the negative  effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by  offsetting the positive  effect of favorable  price
    movements  in  the hedged  investments. For  example,  if a  Theme Portfolio
    entered into a short  hedge because the Sub-adviser  projected a decline  in
    the price of a security in the Theme Portfolio's portfolio, and the price of
    that security increased instead, the gain from that increase might be wholly
    or  partially offset by  a decline in  the price of  the hedging instrument.
    Moreover, if the price of the  hedging instrument declined by more than  the
    increase  in the price of  the security, the Theme  Portfolio could suffer a
    loss. In either such case, the Theme  Portfolio would have been in a  better
    position had it not hedged at all.
 
        (4)  As described below, a Theme Portfolio might be required to maintain
    assets as "cover," maintain segregated accounts or make margin payments when
    it takes positions  in instruments  involving obligations  to third  parties
    (i.e.,  instruments other  than purchased  options). If  the Theme Portfolio
    were unable to  close out  its positions in  such instruments,  it might  be
    required  to  continue to  maintain  such assets  or  accounts or  make such
    payments until  the  position expired  or  matured. The  requirements  might
    impair the Theme Portfolio's ability to sell a portfolio security or make an
    investment  at a  time when  it would  otherwise be  favorable to  do so, or
    require  that  the  Theme   Portfolio  sell  a   portfolio  security  at   a
    disadvantageous  time. The Theme Portfolio's ability to close out a position
    in an instrument
 
                   Statement of Additional Information Page 8
<PAGE>
                             AIM GLOBAL THEME FUNDS
    prior to  expiration  or maturity  depends  on  the existence  of  a  liquid
    secondary  market  or, in  the absence  of  such a  market, the  ability and
    willingness of the other party to the transaction ("contra party") to  enter
    into  a  transaction  closing  out  the  position.  Therefore,  there  is no
    assurance that any position can  be closed out at a  time and price that  is
    favorable to the Theme Portfolio.
 
WRITING CALL OPTIONS
Each  Theme Portfolio may  write (sell) call options  on securities, indices and
currencies. Call options generally will be written on securities and  currencies
that, in the opinion of the Sub-adviser are not expected to make any major price
moves  in  the near  future  but that,  over  the long  term,  are deemed  to be
attractive investments for the Theme Portfolios.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
style) or an (European style) a certain  date (the expiration date). So long  as
the  obligation of  the writer  of a  call option  continues, he  or she  may be
assigned an exercise  notice, requiring  him or  her to  deliver the  underlying
security  or currency  against payment  of the  exercise price.  This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer  effects  a closing  purchase  transaction by  purchasing  an  option
identical to that previously sold.
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on the basis of investment considerations consistent with  each
Theme  Portfolio's investment  objective. When  writing a  call option,  a Theme
Portfolio, in return for the premium, gives up the opportunity for profit from a
price increase in the underlying security or currency above the exercise  price,
and  retains  the risk  of loss  should the  price of  the security  or currency
decline. Unlike one who owns securities or currencies not subject to an  option,
a  Theme Portfolio  has no  control over  when it  may be  required to  sell the
underlying securities or currencies, since most options may be exercised at  any
time  prior to the option's expiration. If  a call option that a Theme Portfolio
has written expires, the Theme  Portfolio will realize a  gain in the amount  of
the  premium; however, such gain may be offset  by a decline in the market value
of the underlying  security or currency  during the option  period. If the  call
option  is exercised, the Theme  Portfolio will realize a  gain or loss from the
sale of the underlying security or  currency, which will be increased or  offset
by  the premium received. Each  Theme Portfolio does not  consider a security or
currency covered by a call option to be  "pledged" as that term is used in  that
Theme Portfolio's policy that limits the pledging or mortgaging of its assets.
 
Writing  call options can serve as a limited short hedge because declines in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
appreciates to a price higher than the exercise price of the call option, it can
be expected that  the option will  be exercised  and a Theme  Portfolio will  be
obligated to sell the security or currency at less than its market value.
 
The  premium that a Theme Portfolio receives for writing a call option is deemed
to constitute the  market value of  an option. The  premium the Theme  Portfolio
will  receive from writing a  call option will reflect,  among other things, the
current market  price of  the  underlying investment,  the relationship  of  the
exercise  price to  such market  price, the  historical price  volatility of the
underlying investment,  and the  length  of the  option period.  In  determining
whether  a  particular  call  option should  be  written,  the  Sub-adviser will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing transactions  will  be effected  in  order to  realize  a profit  on  an
outstanding  call option,  to prevent  an underlying  security or  currency from
being called, or  to permit  the sale of  the underlying  security or  currency.
Furthermore,  effecting a closing  transaction will permit  a Theme Portfolio to
write another call option on the  underlying security or currency with either  a
different exercise price or expiration date, or both.
 
Each  Theme Portfolio will pay transaction  costs in connection with the writing
of options and in  entering into closing  purchase contracts. Transaction  costs
relating  to  options  activity are  normally  higher than  those  applicable to
purchases and sales of portfolio securities.
 
The exercise price of the  options may be below, equal  to or above the  current
market  values of the  underlying securities, indices or  currencies at the time
the options are written. From  time to time, a  Theme Portfolio may purchase  an
underlying  security or currency for delivery in accordance with the exercise of
an option, rather than delivering such security or currency from its  portfolio.
In such cases, additional costs will be incurred.
 
A  Theme  Portfolio  will realize  a  profit  or loss  from  a  closing purchase
transaction if the cost of the  transaction is less or more, respectively,  than
the  premium received from  writing the option. Because  increases in the market
price of a call option generally will  reflect increases in the market price  of
the   underlying   security   or   currency,  any   loss   resulting   from  the
 
                   Statement of Additional Information Page 9
<PAGE>
                             AIM GLOBAL THEME FUNDS
repurchase of a  call option  is likely  to be  offset in  whole or  in part  by
appreciation of the underlying security or currency owned by a Theme Portfolio.
 
WRITING PUT OPTIONS
Each   Theme  Portfolio  may  write  put  options  on  securities,  indices  and
currencies. A put option gives  the purchaser of the  option the right to  sell,
and  the  writer (seller)  the  obligation to  buy,  the underlying  security or
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style) the  expiration date.  The operation  of put  options in other
respects, including their related risks and rewards, is substantially  identical
to that of call options.
 
A  Theme Portfolio generally would write  put options in circumstances where the
Sub-adviser wishes to purchase the underlying  security or currency for a  Theme
Portfolio's  holdings at  a price  lower than  the current  market price  of the
security or currency. In such event, a Theme Portfolio would write a put  option
at  an  exercise price  that, reduced  by  the premium  received on  the option,
reflects the lower price it is willing  to pay. Since the Theme Portfolio  would
also  receive interest on debt securities  or currencies maintained to cover the
exercise price of the  option, this technique could  be used to enhance  current
return  during periods  of market  uncertainty. The  risk in  such a transaction
would be that  the market  price of the  underlying security  or currency  would
decline below the exercise price less the premium received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected that the put option will be exercised and a Theme Portfolio will be
obligated to purchase the security or currency at greater than its market value.
 
PURCHASING PUT OPTIONS
Each Theme  Portfolio  may  purchase  put options  on  securities,  indices  and
currencies.  As the  holder of a  put option,  a Theme Portfolio  would have the
right to sell the underlying security or  currency at the exercise price at  any
time  until (American style) or on (European style) the expiration date. A Theme
Portfolio may enter into closing sale transactions with respect to such options,
exercise such option or permit such option to expire.
 
Each Theme Portfolio  may purchase  a put option  on an  underlying security  or
currency  ("protective put")  owned by the  Theme Portfolio in  order to protect
against an anticipated decline  in the value of  the security or currency.  Such
hedge  protection is provided  only during the  life of the  put option when the
Theme Portfolio, as the holder of the put option, is able to sell the underlying
security or currency at the put exercise price regardless of any decline in  the
underlying  security's market  price or  currency's exchange  value. The premium
paid for  the put  option and  any  transaction costs  would reduce  any  profit
otherwise available for distribution when the security or currency is eventually
sold.
 
A  Theme Portfolio may also purchase put options  at a time when it does not own
the underlying security or currency. By purchasing put options on a security  or
currency  it does not own, that Theme  Portfolio seeks to benefit from a decline
in the market price of the underlying security or currency. If the put option is
not sold when it has remaining value, and if the market price of the  underlying
security  or currency remains equal to or greater than the exercise price during
the life of the put option, the Theme Portfolio will lose its entire  investment
in  the put option. In order for the  purchase of a put option to be profitable,
the  market  price  of  the   underlying  security  or  currency  must   decline
sufficiently  below  the exercise  price to  cover  the premium  and transaction
costs, unless the put option is sold in a closing sale transaction.
 
PURCHASING CALL OPTIONS
Each Theme  Portfolio  may purchase  call  options on  securities,  indices  and
currencies.  As the holder of a call  option, the Theme Portfolio would have the
right to purchase the underlying security  or currency at the exercise price  at
any  time until (American style)  or on (European style)  the expiration date. A
Theme Portfolio may enter  into closing sale transactions  with respect to  such
options, exercise such options or permit such options to expire.
 
Call  options may be purchased by a Theme Portfolio for the purpose of acquiring
the underlying security or currency for its portfolio. Utilized in this fashion,
the purchase  of call  options would  enable a  Theme Portfolio  to acquire  the
security  or currency at the exercise price  of the call option plus the premium
paid. At times,  the net  cost of  acquiring the  security or  currency in  this
manner may be less than the cost of acquiring the security or currency directly.
This  technique may also  be useful to  a Theme Portfolio  in purchasing a large
block of securities  that would be  more difficult to  acquire by direct  market
purchases.  So long as it  holds such a call  option, rather than the underlying
security or currency itself, the Theme Portfolio is partially protected from any
unexpected decline in the  market price of the  underlying security or  currency
and, in such event, could allow the call option to expire, incurring a loss only
to the extent of the premium paid for the option.
 
A  Theme Portfolio  may also purchase  call options on  underlying securities or
currencies it owns to avoid realizing losses that would result in a reduction of
its current return.  For example,  where a Theme  Portfolio has  written a  call
option on an
 
                  Statement of Additional Information Page 10
<PAGE>
                             AIM GLOBAL THEME FUNDS
underlying security or currency having a current market value below the price at
which  it purchased the  security or currency,  an increase in  the market price
could result in the exercise of the  call option written by the Theme  Portfolio
and  the  realization  of  a  loss  on  the  underlying  security  or  currency.
Accordingly, the  Theme Portfolio  could  purchase a  call  option on  the  same
underlying  security or currency, which could  be exercised to fulfill the Theme
Portfolio's delivery obligations under  its written call  (if it is  exercised).
This  strategy could  allow the Theme  Portfolio to avoid  selling the portfolio
security or currency  at a time  when it  has an unrealized  loss; however,  the
Theme  Portfolio would have  to pay a  premium to purchase  the call option plus
transaction costs.
 
Aggregate premiums paid  for put and  call options  will not exceed  5% of  each
Theme Portfolio's total assets at the time of each purchase.
 
A Theme Portfolio may attempt to accomplish objectives similar to those involved
in  using Forward Contracts by  purchasing put or call  options on currencies. A
put option  gives  the Theme  Portfolio  as purchaser  the  right (but  not  the
obligation)  to sell a specified amount of currency at the exercise price at any
time until (American style)  or on (European style)  the expiration date of  the
option.  A call option gives the Theme Portfolio as purchaser the right (but not
the obligation) to purchase a specified amount of currency at the exercise price
at any time until (American style) or on (European style) the expiration date of
the option. A Theme Portfolio might purchase a currency put option, for example,
to protect itself against a decline in  the dollar value of a currency in  which
it  holds  or anticipates  holding securities.  If  the currency's  value should
decline against the  dollar, the  loss in currency  value should  be offset,  in
whole  or in part, by an  increase in the value of the  put. If the value of the
currency instead should rise against the  dollar, any gain to a Theme  Portfolio
would  be reduced by the premium it had paid for the put option. A currency call
option might  be purchased,  for  example, in  anticipation  of, or  to  protect
against,  a rise in the value against the  dollar of a currency in which a Theme
Portfolio anticipates purchasing securities.
 
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing  corporation) and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates. A Theme Portfolio will not purchase an OTC option unless it believes that
daily valuations for  such options  are readily obtainable.  OTC options  differ
from  exchange-traded options  in that OTC  options are  transacted with dealers
directly and not through a clearing corporation (which guarantees  performance).
Consequently,  there  is  a risk  of  non-performance  by the  dealer.  Since no
exchange is involved, OTC options are valued  on the basis of an average of  the
last  bid prices obtained from dealers, unless  a quotation from only one dealer
is available, in which case only that  dealer's price will be used. In the  case
of  OTC options, there can  be no assurance that  a liquid secondary market will
exist for any particular option at any specific time.
 
The staff of the SEC considers purchased OTC options to be illiquid  securities.
A  Theme  Portfolio may  also  sell OTC  options  and, in  connection therewith,
segregate assets or cover its obligations with respect to OTC options written by
the Theme Portfolio. The assets used as cover for OTC options written by a Theme
Portfolio will  be  considered illiquid  unless  the  OTC options  are  sold  to
qualified  dealers who  agree that  the Theme  Portfolio may  repurchase any OTC
option it writes at a maximum price to  be calculated by a formula set forth  in
the  option  agreement. The  cover for  an  OTC option  written subject  to this
procedure would  be considered  illiquid only  to the  extent that  the  maximum
repurchase price under the formula exceeds the intrinsic value of the option.
 
A   Theme  Portfolio's  ability   to  establish  and   close  out  positions  in
exchange-listed options depends  on the existence  of a liquid  market. A  Theme
Portfolio  intends to purchase  or write only  those exchange-traded options for
which there appears to be  a liquid secondary market.  However, there can be  no
assurance  that  such  a  market  will exist  at  any  particular  time. Closing
transactions can be made for OTC  options only by negotiating directly with  the
contra  party or  by a transaction  in the  secondary market if  any such market
exists. Although a Theme Portfolio will enter into OTC options only with  contra
parties  that are expected  to be capable of  entering into closing transactions
with the Theme Portfolio, there is no assurance that the Theme Portfolio will in
fact be able to close out an OTC  option position at a favorable price prior  to
expiration.  In the event of insolvency of the contra party, the Theme Portfolio
might be unable to  close out an OTC  option position at any  time prior to  its
expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts  except that all settlements  are in cash and  gain or loss depends on
changes in the index in question (and thus on price movements in the  securities
market  or a particular market sector  generally) rather than on price movements
in individual securities or futures contracts.  When a Theme Portfolio writes  a
call on an index, it receives a premium and agrees that, prior to the expiration
date,  the purchaser of the  call, upon exercise of  the call, will receive from
the   Theme   Portfolio   an   amount    of   cash   if   the   closing    level
 
                  Statement of Additional Information Page 11
<PAGE>
                             AIM GLOBAL THEME FUNDS
of  the index upon which the call is based is greater than the exercise price of
the call. The  amount of cash  is equal  to the difference  between the  closing
price of the index and the exercise price of the call times a specified multiple
(the  "multiplier"), which determines  the total dollar value  for each point of
such difference. When  a Theme  Portfolio buys  a call on  an index,  it pays  a
premium  and has the same rights as to  such call as are indicated above. When a
Theme Portfolio buys a  put on an index,  it pays a premium  and has the  right,
prior  to the expiration date, to require the  seller of the put, upon the Theme
Portfolio's exercise of the put, to deliver to the Theme Portfolio an amount  of
cash  if the closing level of the index upon which the put is based is less than
the exercise  price of  the  put, which  amount of  cash  is determined  by  the
multiplier, as described above for calls. When a Theme Portfolio writes a put on
an  index, it receives a  premium and the purchaser has  the right, prior to the
expiration date, to require the  Theme Portfolio to deliver  to it an amount  of
cash  equal to  the difference between  the closing  level of the  index and the
exercise price  times the  multiplier, if  the closing  level is  less than  the
exercise price.
 
The  risks  of  investment in  index  options  may be  greater  than  options on
securities. Because index options  are settled in cash,  when a Theme  Portfolio
writes  a  call on  an  index it  cannot provide  in  advance for  its potential
settlement obligations by  acquiring and  holding the  underlying securities.  A
Theme  Portfolio can  offset some  of the  risk of  writing a  call index option
position by holding a  diversified portfolio of securities  similar to those  on
which  the underlying index  is based. However,  a Theme Portfolio  cannot, as a
practical matter,  acquire and  hold  a portfolio  containing exactly  the  same
securities  as underlie the index and, as a  result, bears a risk that the value
of the securities held will vary from the value of the index.
 
Even if a  Theme Portfolio could  assemble a securities  portfolio that  exactly
reproduced  the composition of the underlying index, it still would not be fully
covered from a risk standpoint because of the "timing risk" inherent in  writing
index  options. When an index  option is exercised, the  amount of cash that the
holder is  entitled to  receive  is determined  by  the difference  between  the
exercise  price  and the  closing index  level on  the date  when the  option is
exercised. As with  other kinds  of options, the  Theme Portfolio,  as the  call
writer,  will not know that it has been  assigned until the next business day at
the earliest. The time  lag between exercise and  notice of assignment poses  no
risk for the writer of a covered call on a specific underlying security, such as
common stock, because there the writer's obligation is to deliver the underlying
security,  not to pay its value  as of a fixed time in  the past. So long as the
writer already  owns the  underlying  security, it  can satisfy  its  settlement
obligations  by  simply delivering  it, and  the  risk that  its value  may have
declined since the exercise date is borne by the exercising holder. In contrast,
even if the  writer of an  index call  holds securities that  exactly match  the
composition  of  the  underlying index,  it  will  not be  able  to  satisfy its
assignment obligations by  delivering those  securities against  payment of  the
exercise  price. Instead, it will be required to  pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that  it
has  been assigned, the index may have declined, with a corresponding decline in
the value  of  its securities  portfolio.  This  "timing risk"  is  an  inherent
limitation  on the ability of index call writers to cover their risk exposure by
holding securities positions.
 
If a  Theme Portfolio  purchases an  index option  and exercises  it before  the
closing  index value for that day is available,  it runs the risk that the level
of the underlying  index may subsequently  change. If such  a change causes  the
exercised  option to fall out-of-the-money, the Theme Portfolio will be required
to pay the difference between the closing index value and the exercise price  of
the option (times the applicable multiplier) to the assigned writer.
 
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
Each Theme Portfolio may enter into interest rate or currency futures contracts,
and  may enter  into stock index  futures contracts  (collectively, "Futures" or
"Futures Contracts"),  as  a  hedge  against changes  in  prevailing  levels  of
interest  rates,  currency exchange  rates  or stock  price  levels in  order to
establish more definitely the effective return on securities or currencies  held
or  intended to be acquired by the  Theme Portfolio. A Theme Portfolio's hedging
may include  sales  of Futures  as  an offset  against  the effect  of  expected
increases  in interest rates, and decreases in currency exchange rates and stock
prices, and purchases  of Futures as  an offset against  the effect of  expected
declines  in interest rates,  and increases in currency  exchange rates or stock
prices.
 
Each Theme Portfolio only will enter  into Futures Contracts that are traded  on
futures  exchanges  and  are standardized  as  to maturity  date  and underlying
financial instrument. Futures exchanges and trading thereon in the United States
are regulated under the Commodity Exchange Act by the Commodity Futures  Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used  to reduce a Theme Portfolio's exposure to interest rate, currency exchange
rate and stock market  fluctuations, that Theme Portfolio  may be able to  hedge
its  exposure  more  effectively  and  at a  lower  cost  through  using Futures
Contracts.

A Futures Contract provides  for the future  sale by one  party and purchase  by
another party of a specified amount of a specific financial instrument (security
or currency) for a specified price at a designated date, time and place. A stock
index Futures Contract provides for the delivery, at a designated date, time and
place,  of  an amount  of  cash equal  to a  specified  dollar amount  times the
difference between the stock index value at the close of trading on the contract
and the price at  which the Futures Contract  is originally struck; no  physical
delivery  of stocks  comprising the index  is made. Brokerage  fees are incurred
when a  Futures  Contract  is  bought  or sold,  and  margin  deposits  must  be
maintained at all times the Futures Contract is outstanding.
 
Although  Futures Contracts typically require future delivery of and payment for
financial instruments or  currencies, Futures Contracts  usually are closed  out
before  the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering  into an offsetting Futures  Contract purchase or  sale,
respectively,   for  the  same  aggregate  amount  of  the  identical  financial
instrument or currency and  the same delivery date.  If the offsetting  purchase
price is less than the original sale price, the Theme Portfolio realizes a gain;
if  it  is  more,  the  Theme Portfolio  realizes  a  loss.  Conversely,  if the
offsetting sale  price is  more  than the  original  purchase price,  the  Theme
Portfolio  realizes a gain; if it is  less, the Theme Portfolio realizes a loss.
The transaction costs must also be included in these calculations. There can  be
no  assurance, however,  that a Theme  Portfolio will  be able to  enter into an
offsetting transaction  with  respect to  a  particular Futures  Contract  at  a
particular  time. If a Theme  Portfolio is not able  to enter into an offsetting
transaction, that Theme Portfolio will continue  to be required to maintain  the
margin deposits on the Futures Contract.
 
As  an example of an offsetting transaction, the contractual obligations arising
from the sale of one Futures Contract of September Deutschemarks on an  exchange
may  be fulfilled  at any  time before  delivery under  the Futures  Contract is
required (I.E., on a specified date  in September, the "delivery month") by  the
purchase  of another  Futures Contract  of September  Deutschemarks on  the same
exchange. In  such instance,  the  difference between  the  price at  which  the
Futures  Contract was sold and the price paid for the offsetting purchase, after
allowance for transaction  costs, represents  the profit  or loss  to the  Theme
Portfolio.
 
Each  Theme Portfolio's  Futures transactions will  be entered  into for hedging
purposes only; that  is, Futures  Contracts will be  sold to  protect against  a
decline in the price of securities or currencies that a Theme Portfolio owns, or
Futures  Contracts will  be purchased  to protect  a Theme  Portfolio against an
increase in the price of securities  or currencies it has committed to  purchase
or expects to purchase.
 
"Margin"  with respect to Futures Contracts is  the amount of funds that must be
deposited by a Theme Portfolio in order to initiate Futures trading and maintain
the Theme Portfolio's open positions in Futures Contracts. A margin deposit made
when the Futures  Contract is  entered into  ("initial margin")  is intended  to
ensure  the Theme Portfolio's performance under the Futures Contract. The margin
required for a particular Futures Contract is  set by the exchange on which  the
Futures  Contract is traded and may be  significantly modified from time to time
by the exchange during the term of the Futures Contract.
 
Subsequent  payments,  called  "variation  margin"  to  and  from  the   futures
commission  merchant through  which the Theme  Portfolio entered  in the Futures
Contract will be made on a daily basis as the price of the underlying  security,
currency  or index fluctuates making the Futures Contract more or less valuable,
a process known as marking-to-market.
 
    RISKS OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts  are
volatile  and  are influenced  by, among  other  things, actual  and anticipated
changes in  interest rates  and currency  exchange rates,  and in  stock  market
movements,  which  in turn  are  affected by  fiscal  and monetary  policies and
national and international political and economic events.
 
There is a risk  of imperfect correlation between  changes in prices of  Futures
Contracts  and prices  of the  securities or  currencies in  a Theme Portfolio's
portfolio being hedged. The degree  of imperfection of correlation depends  upon
circumstances  such as variations  in speculative market  demand for Futures and
for securities or currencies, including technical influences in Futures trading;
and  differences  between  the  financial  instruments  being  hedged  and   the
instruments  underlying the standard Futures  Contracts available for trading. A
decision of whether, when and how to hedge involves skill and judgment, and even
a well-conceived hedge may be unsuccessful to some degree because of  unexpected
market behavior or interest or currency rate trends.
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
 
                  Statement of Additional Information Page 13
<PAGE>
                             AIM GLOBAL THEME FUNDS
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and options on Futures Contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a Futures  Contract
or option may vary either up or down from the previous day's settlement price at
the  end  of a  trading session.  Once the  daily  limit has  been reached  in a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a particular trading day and therefore does not limit potential losses,  because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and  option  prices  have occasionally  moved  to  the daily  limit  for several
consecutive trading days with  little or no  trading, thereby preventing  prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If  a Theme Portfolio  were unable to  liquidate a Futures  or option on Futures
position due to the absence  of a liquid secondary  market or the imposition  of
price  limits,  it could  incur substantial  losses.  The Theme  Portfolio would
continue to be subject to market risk with respect to the position. In addition,
except in the case of purchased  options, the Theme Portfolio would continue  to
be  required to make  daily variation margin  payments and might  be required to
maintain the position being hedged by the  Future or option or to maintain  cash
or securities in a segregated account.
 
Certain  characteristics  of the  Futures market  might  increase the  risk that
movements in the  prices of Futures  Contracts or options  on Futures might  not
correlate  perfectly  with  movements in  the  prices of  the  investments being
hedged. For example,  all participants  in the  Futures and  options on  Futures
markets  are subject to daily  variation margin calls and  might be compelled to
liquidate Futures  or  options on  Futures  positions whose  prices  are  moving
unfavorably  to avoid being  subject to further  calls. These liquidations could
increase price  volatility  of the  instruments  and distort  the  normal  price
relationship  between the Futures  or options and  the investments being hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous than  margin requirements  in  the securities  markets, there  might  be
increased   participation   by  speculators   in   the  Futures   markets.  This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage,  "program trading"  and other  investment strategies  might result in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options on Futures Contracts are similar to options on securities or  currencies
except that options on Futures Contracts give the purchaser the right, in return
for  the  premium paid,  to  assume a  position in  a  Futures Contract  (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price  at any time  during the period  of the option.  Upon
exercise  of the option, the  delivery of the Futures  position by the writer of
the option to the holder  of the option will be  accompanied by delivery of  the
accumulated balance in the writer's Futures margin account, which represents the
amount  by which the market price of  the Futures Contract, at exercise, exceeds
(in the case of  a call) or  is less than (in  the case of  a put) the  exercise
price  of the option on  the Futures Contract. If an  option is exercised on the
last trading day prior to the expiration date of the option, the settlement will
be made entirely in cash equal to  the difference between the exercise price  of
the  option and the  closing level of  the securities, currencies  or index upon
which the  Futures Contract  is  based on  the  expiration date.  Purchasers  of
options  who fail to exercise their options  prior to the exercise date suffer a
loss of the premium paid.
 
The purchase of  call options  on Futures  can serve as  a long  hedge, and  the
purchase  of put  options on Futures  can serve  as a short  hedge. Writing call
options on Futures can serve as a  limited short hedge, and writing put  options
on  Futures can serve as a limited long  hedge, using a strategy similar to that
used for writing options on securities, foreign currencies or indices.
 
If a Theme Portfolio writes an option on a Futures Contract, it will be required
to deposit  initial and  variation margin  pursuant to  requirements similar  to
those  applicable to Futures Contracts. Premiums received from the writing of an
option on a Futures Contract are included in the initial margin deposit.
 
A Theme Portfolio may seek to close out an option position by selling an  option
covering  the  same Futures  Contract  and having  the  same exercise  price and
expiration date.  The ability  to  establish and  close  out positions  on  such
options is subject to the maintenance of a liquid secondary market.
 
LIMITATIONS  ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS ON
CURRENCIES
To the extent that a Theme  Portfolio enters into Futures Contracts, options  on
Futures  Contracts, and options on foreign currencies traded on a CFTC-regulated
exchange, in each case other than for BONA FIDE hedging purposes (as defined  by
the CFTC), the aggregate initial margin and premiums required to establish those
positions  (excluding the amount  by which options  are "in-the-money") will not
exceed 5% of  the liquidation value  of the Theme  Portfolio, after taking  into
 
                  Statement of Additional Information Page 14
<PAGE>
                             AIM GLOBAL THEME FUNDS
account  unrealized profits  and unrealized  losses on  any contracts  the Theme
Portfolio has entered into. In general, a  call option on a Futures Contract  is
"in-the-money"  if  the value  of the  underlying  Futures Contract  exceeds the
strike, I.E., exercise, price of the call; a put option on a Futures Contract is
"in-the-money" if the value  of the underlying Futures  Contract is exceeded  by
the strike price of the put. This guideline may be modified by the Trust's Board
of  Trustees and  the Portfolios'  Board of  Trustees, as  applicable, without a
shareholder vote.  This limitation  does not  limit the  percentage of  a  Theme
Portfolio's assets at risk to 5%.
 
FORWARD CONTRACTS
A  Forward Contract is an obligation, usually arranged with a commercial bank or
other currency dealer, to purchase or  sell a currency against another  currency
at  a future  date and price  as agreed upon  by the parties.  A Theme Portfolio
either may  accept or  make delivery  of the  currency at  the maturity  of  the
Forward  Contract. A Theme Portfolio may also, if its contra party agrees, prior
to maturity, enter into a closing transaction involving the purchase or sale  of
an offsetting contract.
 
A  Theme Portfolio engages in forward  currency transactions in anticipation of,
or to protect itself against, fluctuations in exchange rates. A Theme  Portfolio
might  sell a  particular foreign currency  forward, for example,  when it holds
bonds denominated  in  a foreign  currency  but  anticipates, and  seeks  to  be
protected against, a decline in the currency against the U.S. dollar. Similarly,
a  Theme  Portfolio might  sell  the U.S.  dollar  forward when  it  holds bonds
denominated in U.S. dollars but anticipates, and seeks to be protected  against,
a  decline in  the U.S.  dollar relative to  other currencies.  Further, a Theme
Portfolio might purchase a currency forward to "lock in" the price of securities
denominated in that currency that it anticipates purchasing.
 
Forward Contracts are traded in the interbank market conducted directly  between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any  stage  for  trades.  Each  Theme Portfolio  will  enter  into  such Forward
Contracts with major U.S. or foreign banks and securities or currency dealers in
accordance with guidelines approved by the  Trust's or the Portfolios' Board  of
Trustees, as applicable.
 
A  Theme  Portfolio may  enter  into Forward  Contracts  either with  respect to
specific transactions  or with  respect  to overall  investments of  that  Theme
Portfolio. The precise matching of the Forward Contract amounts and the value of
specific  securities generally will not be  possible because the future value of
such securities in  foreign currencies will  change as a  consequence of  market
movements in the value of those securities between the date the Forward Contract
is  entered into and the  date it matures. Accordingly,  it may be necessary for
that Theme Portfolio to purchase additional foreign currency on the spot  (I.E.,
cash)  market (and bear the expense of such purchase) if the market value of the
security is less  than the  amount of foreign  currency the  Theme Portfolio  is
obligated  to deliver and  if a decision is  made to sell  the security and make
delivery of the foreign currency. Conversely, it may be necessary to sell on the
spot market some  of the foreign  currency the Theme  Portfolio is obligated  to
deliver.  The projection  of short-term  currency market  movements is extremely
difficult, and  the successful  execution of  a short-term  hedging strategy  is
highly  uncertain. Forward Contracts involve  the risk that anticipated currency
movements will not be predicted accurately, causing a Theme Portfolio to sustain
losses on these contracts and transaction costs.
 
At or before the maturity of a  Forward Contract requiring a Theme Portfolio  to
sell  a currency, that  Theme Portfolio either  may sell a  security and use the
sale proceeds to make delivery of the currency or retain the security and offset
its contractual  obligation  to deliver  the  currency by  purchasing  a  second
contract pursuant to which the Theme Portfolio will obtain, on the same maturity
date,  the  same  amount  of  the currency  that  it  is  obligated  to deliver.
Similarly, a Theme Portfolio  may close out a  Forward Contract requiring it  to
purchase  a specified currency by entering into a second contract, if its contra
party agrees, entitling it to sell the  same amount of the same currency on  the
maturity  date of the first contract. A  Theme Portfolio would realize a gain or
loss as a  result of  entering into such  an offsetting  Forward Contract  under
either  circumstance  to  the extent  the  exchange  rate or  rates  between the
currencies involved moved between the execution dates of the first contract  and
the offsetting contract.
 
The  cost to  a Theme  Portfolio of  engaging in  Forward Contracts  varies with
factors such as the currencies involved,  the length of the contract period  and
the  market conditions  then prevailing.  Because Forward  Contracts are usually
entered into on a principal basis, no fees or commissions are involved. The  use
of  Forward  Contracts does  not  eliminate fluctuations  in  the prices  of the
underlying securities a Theme Portfolio owns or intends to acquire, but it  does
establish  a rate  of exchange in  advance. In addition,  while Forward Contract
sales limit  the risk  of loss  due to  a decline  in the  value of  the  hedged
currencies,  they also  limit any  potential gain  that might  result should the
value of the currencies increase.

FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
A Theme Portfolio  may use  options on  foreign currencies,  Futures on  foreign
currencies,  options on Futures on foreign  currencies and Forward Contracts, to
hedge against movements  in the values  of the foreign  currencies in which  the
Theme  Portfolio's securities are denominated.  Such currency hedges can protect
against price movements in a security  that the Theme Portfolio owns or  intends
to  acquire that  are attributable to  changes in  the value of  the currency in
which it is  denominated. Such  hedges do  not, however,  protect against  price
movements in the securities that are attributable to other causes.
 
A  Theme  Portfolio  might seek  to  hedge against  changes  in the  value  of a
particular currency  when  no  Futures  Contract,  Forward  Contract  or  option
involving  that currency is available or one of such contracts is more expensive
than certain  other contracts.  In such  cases, the  Theme Portfolio  may  hedge
against  price movements in that currency by entering into a contract on another
currency or basket of currencies, the  values of which the Sub-adviser  believes
will  have a positive correlation to the value of the currency being hedged. The
risk that movements in  the price of the  contract will not correlate  perfectly
with  movements in the price of the currency being hedged is magnified when this
strategy is used.
 
The value of Futures Contracts, options on Futures Contracts, Forward  Contracts
and  options  on  foreign currencies  depends  on  the value  of  the underlying
currency relative  to the  U.S. dollar.  Because foreign  currency  transactions
occurring  in the  interbank market  might involve  substantially larger amounts
than those  involved in  the  use of  Futures  Contracts, Forward  Contracts  or
options,  a Theme  Portfolio could  be disadvantaged by  dealing in  the odd lot
market (generally consisting of  transactions of less than  $1 million) for  the
underlying  foreign currencies at prices that  are less favorable than for round
lots.
 
There is no systematic reporting of last sale information for foreign currencies
or any  regulatory requirements  that quotations  available through  dealers  or
other market sources be firm or revised on a timely basis. Quotation information
generally  is representative of very large  transactions in the interbank market
and thus  might not  reflect  odd-lot transactions  where  rates might  be  less
favorable.   The   interbank  market   in  foreign   currencies  is   a  global,
round-the-clock market. To the  extent the U.S. options  or Futures markets  are
closed  while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that  cannot
be  reflected in  the markets  for the Futures  contracts or  options until they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies might  be required  to  take place  within  the country  issuing  the
underlying currency. Thus, a Theme Portfolio might be required to accept or make
delivery  of  the underlying  foreign currency  in accordance  with any  U.S. or
foreign regulations regarding the maintenance of foreign banking arrangements by
U.S. residents  and  might  be required  to  pay  any fees,  taxes  and  charges
associated with such delivery assessed in the issuing country.
 
COVER
Transactions  using Forward Contracts, Futures Contracts and options (other than
options purchased  by  a Theme  Portfolio)  expose  the Theme  Portfolio  to  an
obligation  to another  party. A  Theme Portfolio will  not enter  into any such
transactions unless it  owns either  (1) an offsetting  ("covered") position  in
securities, currencies, or other options, Forward Contracts or Future Contracts,
or  (2) cash, receivables and short-term debt securities with a value sufficient
at all times to cover its potential  obligations not covered as provided in  (1)
above.  Each Theme Portfolio will comply with SEC guidelines regarding cover for
these instruments and, if  the guidelines so require,  set aside cash or  liquid
securities.
 
Assets  used as cover or  held in a segregated account  cannot be sold while the
position in the corresponding  Forward Contract, Futures  Contract or option  is
open, unless they are replaced with other appropriate assets. If a large portion
of a Theme Portfolio's assets is used for cover or otherwise set aside, it could
affect  portfolio management or the Theme Portfolio's ability to meet redemption
requests or other current obligations.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
Each Theme  Portfolio  may invest  up  to 15%  of  its net  assets  in  illiquid
securities.  Securities may be  considered illiquid if  a Theme Portfolio cannot
reasonably expect within seven days to  sell the security for approximately  the
amount  at which  that Theme Portfolio  values such  securities. See "Investment
Limitations." The  sale of  illiquid securities,  if they  can be  sold at  all,
generally  will  require more  time and  result in  higher brokerage  charges or
dealer discounts  and  other selling  expenses  than  will the  sale  of  liquid
securities  such as securities eligible for trading on U.S. securities exchanges
or in OTC markets.  Moreover, restricted securities, which  may be illiquid  for
purposes  of  this limitation,  often sell,  if at  all, at  a price  lower than
similar securities that are not subject to restrictions on resale.
 
Illiquid securities include those that are subject to restrictions contained  in
the  securities laws  of other  countries. However,  securities that  are freely
marketable in the country  where they are principally  traded, but would not  be
freely  marketable in the United States,  will not be considered illiquid. Where
registration is required, a Theme Portfolio may be obligated to pay all or  part
of  the registration expenses  and a considerable period  may elapse between the
time of the decision to sell and  the time the Theme Portfolio may be  permitted
to  sell a security under an effective registration statement. If, during such a
period, adverse market  conditions were  to develop, the  Theme Portfolio  might
obtain a less favorable price than prevailed when it decided to sell.
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under the Securities Act of 1933, as amended ("1933 Act"), including
private placements, repurchase agreements, commercial paper, foreign  securities
and corporate bonds and notes. These instruments are often restricted securities
because  the  securities are  sold in  transactions not  requiring registration.
Institutional investors generally will not seek to sell these instruments to the
general  public,  but  instead  will   often  depend  either  on  an   efficient
institutional market in which such unregistered securities can be readily resold
or  on an issuer's ability to honor  a demand for repayment. Therefore, the fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the  1933 Act  for resales  of certain  securities to qualified
institutional buyers.  Institutional  markets  for  restricted  securities  have
developed  as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to  satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance  and  settlement of  unregistered securities  of domestic  and foreign
issuers, such as  the PORTAL  System sponsored  by the  National Association  of
Securities  Dealers,  Inc.  An insufficient  number  of  qualified institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a Theme Portfolio,  however, could  affect adversely the  marketability of  such
portfolio  securities and the Theme Portfolio might be unable to dispose of such
securities promptly or at favorable prices.
 
With  respect  to  liquidity  determinations  generally,  the  Trust's  or   the
Portfolios'  Board of Trustees,  as applicable, has  the ultimate responsibility
for determining  whether specific  securities, including  restricted  securities
pursuant to Rule 144A under the 1933 Act, are liquid or illiquid. Each Board has
delegated  the function of making day-to-day  determinations of liquidity to the
Sub-adviser,  in  accordance  with  procedures  approved  by  that  Board.   The
Sub-adviser  takes  into  account  a number  of  factors  in  reaching liquidity
decisions, including, but not  limited to, (i) the  frequency of trading in  the
security;  (ii) the number of  dealers that make quotes  for the security; (iii)
the number of dealers  that have undertaken  to make a  market in the  security;
(iv)  the  number of  other  potential purchasers;  and  (v) the  nature  of the
security and  how  trading  is effected  (e.g.,  the  time needed  to  sell  the
security,  how  offers  are  solicited  and  the  mechanics  of  transfer).  The
Sub-adviser monitors the liquidity  of securities held  by each Theme  Portfolio
and  periodically reports such determinations to  the Trust's or the Portfolios'
Board of Trustees, as applicable. If  the liquidity percentage restriction of  a
Theme  Portfolio is satisfied at the time of investment, a later increase in the
percentage of illiquid securities held by  the Theme Portfolio resulting from  a
change  in  market value  or  assets will  not  constitute a  violation  of that
restriction. If  as  a  result of  a  change  in market  value  or  assets,  the
percentage  of illiquid securities  held by the  Theme Portfolio increases above
the applicable limit, the Sub-adviser will  take appropriate steps to bring  the
aggregate amount of illiquid assets back within the

                             AIM GLOBAL THEME FUNDS
prescribed  limitations as soon  as reasonably practicable,  taking into account
the effect of any disposition on the Theme Portfolio.
 
FOREIGN SECURITIES
    POLITICAL, SOCIAL AND  ECONOMIC RISKS. Investing  in securities of  non-U.S.
companies may entail additional risks due to the potential political, social and
economic  instability  of  certain  countries and  the  risks  of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment convertibility of currencies into U.S. dollars and on repatriation of
capital  invested. In the event of  such expropriation, nationalization or other
confiscation by any country, a Theme Portfolio could lose its entire  investment
in any such country.
 
    RELIGIOUS,  POLITICAL AND ETHNIC  INSTABILITY. Certain countries  in which a
Theme Portfolio may invest  may have groups that  advocate radical religious  or
revolutionary  philosophies or  support ethnic independence.  Any disturbance on
the  part  of  such  individuals  could  carry  the  potential  for   widespread
destruction  or  confiscation  of  property owned  by  individuals  and entities
foreign to  such  country  and could  cause  the  loss of  a  Theme  Portfolio's
investment  in those  countries. Instability may  also result  from, among other
things; (i) authoritarian governments or  military involvement in political  and
economic    decision-making,   including    changes   in    government   through
extra-constitutional means;  (ii) popular  unrest  associated with  demands  for
improved  political, economic and social conditions; and (iii) hostile relations
with neighboring  or  other  countries.  Such  political,  social  and  economic
instability  could  disrupt the  principal financial  markets  in which  a Theme
Portfolio invests and adversely affect the value of a Theme Portfolio's assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity  markets, by  foreign entities  such as  a Theme  Portfolio.  These
restrictions  or controls may  at times limit or  preclude investment in certain
securities and may  increase the  cost and expenses  of a  Theme Portfolio.  For
example,   certain   countries  require   prior  governmental   approval  before
investments by  foreign  persons  may  be  made, or  may  limit  the  amount  of
investment by foreign persons in a particular company or limit the investment by
foreign  persons to only  a specific class  of securities of  a company that may
have less  advantageous  terms than  securities  of the  company  available  for
purchase  by nationals. Moreover, the national policies of certain countries may
restrict investment opportunities in issuers  or industries deemed sensitive  to
national  interests. In  addition, some countries  require governmental approval
for the repatriation of investment income, capital or the proceeds of securities
sales by  foreign investors.  In addition,  if  there is  a deterioration  in  a
country's  balance  of  payments of  for  other  reasons, a  country  may impose
restrictions on foreign capital remittances  abroad. A Theme Portfolio could  be
adversely   affected  by  delays  in,  or  a  refusal  to  grant,  any  required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
 
    NON-UNIFORM  CORPORATE  DISCLOSURE  STANDARDS  AND  GOVERNMENTAL REGULATION.
Foreign companies are  subject to accounting,  auditing and financial  standards
and requirements that differ, in some cases significantly, from those applicable
to  U.S. companies. In particular, the assets, liabilities and profits appearing
on the financial  statements of  such a company  may not  reflect its  financial
position  or results of operations  in the way they  would be reflected had such
financial statements been  prepared in accordance  with U.S. generally  accepted
accounting  principles. Most of the foreign securities held by a Theme Portfolio
will not be registered with  the SEC or regulators  of any foreign country,  nor
will  the issuers thereof be subject  to the SEC's reporting requirements. Thus,
there will  be less  available information  concerning most  foreign issuers  of
securities  held by a Theme Portfolio than is available concerning U.S. issuers.
In instances  where the  financial statements  of an  issuer are  not deemed  to
reflect  accurately the financial situation of  the issuer, the Sub-adviser will
take appropriate steps to  evaluate the proposed  investment, which may  include
on-site   inspection  of  the   issuer,  interviews  with   its  management  and
consultations  with  accountants,  bankers  and  other  specialists.  There   is
substantially  less publicly available information  about foreign companies than
there are  reports and  ratings  published about  U.S.  companies and  the  U.S.
government.  In addition, where public information  is available, it may be less
reliable than such information regarding U.S. issuers. Issuers of securities  in
foreign jurisdictions are generally not subject to the same degree of regulation
as  are U.S.  issuers with  respect to  such matters  as restrictions  on market
manipulation, insider trading rules,  shareholder proxy requirements and  timely
disclosure of information.
 
    CURRENCY   FLUCTUATIONS.   Because  each   Theme  Portfolio,   under  normal
circumstances, will invest  a substantial  portion of  its total  assets in  the
securities  of foreign issuers which are  denominated in foreign currencies, the
strength or weakness  of the U.S.  dollar against such  foreign currencies  will
account for part of a Theme Portfolio's investment performance. A decline in the
value of any particular currency against the U.S. dollar will cause a decline in
the  U.S. dollar value of that Theme Portfolio's holdings of securities and cash
denominated in such currency  and, therefore, will cause  an overall decline  in
the appropriate Fund's net asset value and any net investment income and capital
gains  derived  from  such  securities  to be  distributed  in  U.S.  dollars to
shareholders of that Fund. Moreover, if  the value of the foreign currencies  in
 
                  Statement of Additional Information Page 18
<PAGE>
                             AIM GLOBAL THEME FUNDS
which  a Theme Portfolio receives  its income falls relative  to the U.S. dollar
between receipt of the income and  the making of Theme Portfolio  distributions,
the  Theme Portfolio may  be required to  liquidate securities in  order to make
distributions if the Theme  Portfolio has insufficient cash  in U.S. dollars  to
meet distribution requirements.
 
The  rate of exchange between the U.S. dollar and other currencies is determined
by several factors, including the  supply and demand for particular  currencies,
central  bank efforts to support particular currencies, the relative movement of
interest rates and the pace of business activity in the other countries and  the
United  States, and other economic and  financial conditions affecting the world
economy.
 
Although each Theme Portfolio values its assets daily in terms of U.S.  dollars,
the  Portfolios do  not intend to  convert their holdings  of foreign currencies
into U.S. dollars  on a daily  basis. Each Portfolio  will do so,  from time  to
time,  and  investors  should be  aware  of  the costs  of  currency conversion.
Although foreign exchange dealers  do not charge a  fee for conversion, they  do
realize  a profit based on the difference ("spread") between the prices at which
they buy and sell various currencies. Thus, a dealer may offer to sell a foreign
currency to a Portfolio at  one rate, while offering  a lesser rate of  exchange
should a Portfolio desire to sell the currency to the dealer.
 
    ADVERSE  MARKET CHARACTERISTICS. Securities  of many foreign  issuers may be
less liquid and their  prices more volatile than  securities of comparable  U.S.
issuers.  In  addition, foreign  securities  markets and  brokers  generally are
subject to  less governmental  supervision  and regulation  than in  the  United
States,  and  foreign  securities  transactions  usually  are  subject  to fixed
commissions, which  generally are  higher than  negotiated commissions  on  U.S.
transactions.  In addition,  foreign securities  transactions may  be subject to
difficulties associated  with the  settlement of  such transactions.  Delays  in
settlement  could result in  temporary periods when assets  of a Theme Portfolio
are uninvested  and  no return  is  earned thereon.  The  inability of  a  Theme
Portfolio  to make intended security purchases  due to settlement problems could
cause  that  Theme  Portfolio  to  miss  attractive  investment   opportunities.
Inability  to dispose of a portfolio  security due to settlement problems either
could result in  losses to that  Theme Portfolio due  to subsequent declines  in
value  of the portfolio security or, if  that Theme Portfolio has entered into a
contract to  sell  the security,  could  result  in possible  liability  to  the
purchaser.  The Sub-adviser will consider such difficulties when determining the
allocation of  a Theme  Portfolio's assets,  although the  Sub-adviser does  not
believe  that such difficulties will  have a material adverse  effect on a Theme
Portfolio's portfolio trading activities.
 
Each Theme Portfolio  may use  foreign custodians,  which may  involve risks  in
addition  to those  related to  its use of  U.S. custodians.  Such risks include
uncertainties relating  to determining  and monitoring  the foreign  custodian's
financial  strength, reputation and standing; maintaining appropriate safeguards
concerning that  Theme Portfolio's  investments;  and possible  difficulties  in
obtaining and enforcing judgments against such custodians.
 
    WITHHOLDING TAXES. Each Theme Portfolio's net investment income from foreign
issuers  may be  subject to withholding  taxes by the  foreign issuer's country,
thereby reducing that income or delaying the receipt of income when those  taxes
may be recaptured. See "Taxes."
 
    CONCENTRATION. To the extent a Theme Portfolio invests a significant portion
of its assets in securities of issuers located in a particular country or region
of  the world, such Portfolio may be subject to greater risks and may experience
greater volatility than a fund that is more broadly diversified geographically.
 
    SPECIAL CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The  countries
that  are members of the European Economic Community ("Common Market") (Belgium,
Denmark, France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg,  Netherlands,
Portugal,  Spain, and the United Kingdom)  eliminated certain import tariffs and
quotas and  other trade  barriers with  respect  to one  another over  the  past
several  years. The Sub-adviser  believes that this  deregulation should improve
the prospects  for economic  growth in  many Western  European countries.  Among
other  things, the deregulation could enable  companies domiciled in one country
to avail  themselves  of lower  labor  costs  existing in  other  countries.  In
addition,  this deregulation could benefit companies domiciled in one country by
opening additional  markets for  their goods  and services  in other  countries.
Since,  however, it is not  clear what the exact form  or effect of these Common
Market reforms  will be  on business  in  Western Europe,  it is  impossible  to
predict  the long-term  impact of  the implementation  of these  programs on the
securities owned by a Theme Portfolio.
 
    SPECIAL CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN  COUNTRIES.
Investing  in Russia  and Eastern European  countries involves a  high degree of
risk and special considerations not  typically associated with investing in  the
United  States securities markets, and  should be considered highly speculative.
Such risks include: (1)  delays in settling portfolio  transactions and risk  of
loss  arising out of the system of  share registration and custody; (2) the risk
that it may be impossible  or more difficult than  in other countries to  obtain
and/or  enforce a  judgement; (3) pervasiveness  of corruption and  crime in the
economic system; (4) currency exchange rate volatility and the lack of available
currency hedging

instruments; (5) higher rates of inflation (including the risk of social  unrest
associated  with periods of hyper-inflation) and high unemployment; (6) controls
on foreign  investment and  local practices  disfavoring foreign  investors  and
limitations on repatriation of invested capital, profits and dividends, and on a
fund's  ability to  exchange local  currencies for  U.S. dollars;  (7) political
instability and social unrest and violence; (8) the risk that the governments of
Russia and Eastern European countries may decide not to continue to support  the
economic  reform  programs  implemented  recently  and  could  follow  radically
different political  and/or economic  policies to  the detriment  of  investors,
including non-market-oriented policies such as the support of certain industries
at  the expense  of other  sectors or  investors, or  a return  to the centrally
planned economy  that  existed when  such  countries  had a  communist  form  of
government;  (9)  the  financial  condition  of  companies  in  these countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of international trade;  (11) the risk  that the tax  system in these  countries
will  not  be reformed  to prevent  inconsistent, retroactive  and/or exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly since 1990. The general government position has deteriorated as  a
result  of weakening economic  growth and stimulative  measures taken to support
economic activity and to  restore financial stability.  Although the decline  in
interest   rates  and  fiscal  stimulation   packages  have  helped  to  contain
recessionary forces, uncertainties remain. Japan is also heavily dependent  upon
international  trade, so its  economy is especially  sensitive to trade barriers
and disputes.  Japan has  had  difficult relations  with its  trading  partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible  that  trade sanctions  and other  protectionist measures  could impact
Japan adversely in both the short and the long term.
 
The common  stocks  of many  Japanese  companies trade  at  high  price-earnings
ratios.  Differences  in accounting  methods make  it  difficult to  compare the
earnings of  Japanese companies  with  those of  companies in  other  countries,
especially  in the  U.S. In  general, however, reported  net income  in Japan is
understated relative to  U.S. accounting standards  and this is  one reason  why
price-earnings   ratios  of  the  stocks   of  Japanese  companies  have  tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally  been lower than  in the  U.S., both  of
which  factors tend to result in  lower discount rates and higher price-earnings
ratios in Japan than in the U.S.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes  also exist  between  South Korea  and North  Korea.  In
addition,  the  Theme Portfolios  may  invest in  Hong  Kong, which  reverted to
Chinese Administration on July 1, 1997. Investments in Hong Kong may be  subject
to  expropriation, national,  nationalization or  confiscation, in  which case a
Theme Portfolio could lose its entire investment in Hong Kong. In addition,  the
reversion  of Hong Kong also  presents a risk that the  Hong Kong dollar will be
devalued and  a risk  of possible  loss of  investor confidence  in Hong  Kong's
currency, stock market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
 
                  Statement of Additional Information Page 20
<PAGE>
                             AIM GLOBAL THEME FUNDS
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in   the
securities of companies in emerging markets may entail special risks relating to
potential  political and  economic instability  and the  risks of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment,  convertibility of currencies into  U.S. dollars and on repatriation
of capital  invested. In  the event  of such  expropriation, nationalization  or
other  confiscation  by any  country, a  Theme Portfolio  could lose  its entire
investment in any such country.
 
Emerging securities  markets are  substantially  smaller, less  developed,  less
liquid  and more volatile than the major securities markets. The limited size of
emerging securities markets and  limited trading volume  in issuers compared  to
the  volume of trading in  U.S. securities could cause  prices to be erratic for
reasons apart  from factors  that  affect the  quality  of the  securities.  For
example, limited market size may cause prices to be unduly influenced by traders
who  control  large  positions. Adverse  publicity  and  investors' perceptions,
whether or  not  based on  fundamental  analysis,  may decrease  the  value  and
liquidity  of portfolio  securities, especially  in these  markets. In addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience of financial intermediaries, a lack of modern technology, the  lack
of  a sufficient capital base to expand business operations, and the possibility
of permanent or temporary termination of trading.
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in  more developed markets.  In such  emerging securities markets
there may be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economics  and securities
markets of certain emerging market countries.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
FEEDER FUNDS
The Financial Services  Fund, Infrastructure Fund,  Resources Fund and  Consumer
Products  and Services Fund each has the following fundamental investment policy
to enable  it to  invest  in the  Financial Services  Portfolio,  Infrastructure
Portfolio,  Resources Portfolio  and Consumer  Products and  Services Portfolio,
respectively:
 
Notwithstanding any other investment policy of the Fund, the Fund may invest all
of  its  investable  assets  (cash,   securities  and  receivables  related   to
securities)  in an  open-end management investment  company having substantially
the same investment objective, policies and limitations as the Fund.
 
All other fundamental  investment policies, and  the non-fundamental  investment
policies,  of each  Feeder Fund and  its corresponding  Portfolio are identical.
Therefore, although  the following  discusses the  investment policies  of  each
Portfolio  and its Board of Trustees, it applies equally to each Feeder Fund and
its Board of Trustees.
 
Each Portfolio has adopted the  following investment limitations as  fundamental
policies  that (unless otherwise  noted) may not be  changed without approval by
the affirmative vote of a majority  of the outstanding shares of the  Portfolio.
Whenever  a  Feeder Fund  is requested  to vote  on a  change in  the investment
limitations of its corresponding Portfolio, the Fund will hold a meeting of  its
shareholders and will cast its votes as instructed by its shareholders.
 
No Portfolio may:
 
        (1)  Purchase or sell real estate, except that investments in securities
    of issuers that  invest in  real estate and  investments in  mortgage-backed
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    the  Portfolio  may  exercise  rights  under  agreements  relating  to  such
    securities,  including the right  to enforce security  interests and to hold
    real estate acquired by  reason of such enforcement  until that real  estate
    can be liquidated in an orderly manner;

        (2)  Purchase  or  sell  physical  commodities,  but  the  Portfolio may
    purchase, sell or enter into financial options and futures, forward and spot
    currency contracts,  swap  transactions  and other  financial  contracts  or
    derivative instruments;
 
        (3)  Engage in the business of underwriting securities of other issuers,
    except to the extent that the  Portfolio might be considered an  underwriter
    under  the federal  securities laws  in connection  with its  disposition of
    portfolio securities;
 
        (4) Make loans, except through loans of portfolio securities or  through
    repurchase  agreements, provided that  for purposes of  this limitation, the
    acquisition of bonds, debentures, other  debt securities or instruments,  or
    participations  or  other interests  therein  and investments  in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (5) Issue senior securities or  borrow money, except as permitted  under
    the  1940 Act  and then not  in excess of  33 1/3% of  the Portfolio's total
    assets (including the  amount borrowed  but reduced by  any liabilities  not
    constituting  borrowings)  at the  time of  the  borrowing, except  that the
    Portfolio may  borrow  up to  an  additional 5%  of  its total  assets  (not
    including the amount borrowed) for temporary or emergency purposes; or
 
        (6)  Purchase securities of any one issuer if, as a result, more than 5%
    of the Portfolio's  total assets  would be  invested in  securities of  that
    issuer  or the Portfolio would own or  hold more than 10% of the outstanding
    voting securities of that issuer, except  that up to 25% of the  Portfolio's
    total  assets may be invested without  regard to this limitation, and except
    that this limitation does  not apply to securities  issued or guaranteed  by
    the  U.S.  government, its  agencies or  instrumentalities or  to securities
    issued by other investment companies.
 
The following investment policies of each Portfolio are not fundamental policies
and may  be  changed  by vote  of  the  Portfolios' Board  of  Trustees  without
shareholder approval. No Portfolio may:
 
        (1)  Invest in securities of an issuer if the investment would cause the
    Portfolio to own more than 10% of any class of securities of any one issuer;
 
        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;
 
        (3)  Invest  more than  15% of  its net  assets in  illiquid securities,
    including securities that are illiquid by virtue of the absence of a readily
    available market;
 
        (4) Enter into a futures contract,  an option on a futures contract,  or
    an  option on foreign currency traded  on a CFTC-regulated exchange, in each
    case other than for BONA FIDE hedging purposes (as defined by the CFTC),  if
    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5%  of the liquidation value of the Portfolio's portfolio, after taking into
    account unrealized  profits  and  unrealized losses  on  any  contracts  the
    Portfolio has entered into;
 
        (5)  Borrow money except for temporary or emergency purposes (other than
    to meet redemptions). While  borrowings exceed 5%  of the Portfolio's  total
    assets, the Portfolio will not make any additional investments;
 
        (6)  Invest  more  than 10%  of  its  total assets  in  shares  of other
    investment companies and may not invest more than 5% of its total assets  in
    any one investment company or acquire more than 3% of the outstanding voting
    securities of any one investment company;
 
        (7)  Purchase  securities on  margin, provided  that each  Portfolio may
    obtain short-term credits as may be necessary for the clearance of purchases
    and sales of securities,  and further provided that  the Portfolio may  make
    margin deposits in connection with its use of financial options and futures,
    forward  and spot currency contracts,  swap transactions and other financial
    contracts or derivative instruments; or
 
        (8) Mortgage, pledge, or  hypothecate any of  its assets, provided  that
    this  shall not apply to  the transfer of securities  in connection with any
    permissible borrowing  or  to  collateral arrangements  in  connection  with
    permissible activities.
 
Investors should refer to the Prospectus for further information with respect to
the  investment objective of each Feeder Fund,  which may not be changed without
the approval of Fund shareholders, and its corresponding Portfolio's  investment
objective,  which may be  changed without the approval  of its shareholders, and
other investment policies, techniques and limitations,  which may or may not  be
changed without shareholder approval.

HEALTH CARE FUND
The  Health  Care  Fund  has adopted  the  following  investment  limitations as
fundamental policies, which (unless otherwise noted) may not be changed  without
approval by a majority of the outstanding shares of the Fund.
 
The Health Care Fund may not:
 
        (1)  Purchase or sell real estate, except that investments in securities
    of issuers that  invest in  real estate and  investments in  mortgage-backed
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    the Health Care Fund may exercise  rights under agreements relating to  such
    securities,  including the right  to enforce security  interests and to hold
    real estate acquired by  reason of such enforcement  until that real  estate
    can be liquidated in an orderly manner;
 
        (2)  Engage in the business of underwriting securities of other issuers,
    except to  the extent  that the  Health  Care Fund  might be  considered  an
    underwriter  under  the  federal  securities  laws  in  connection  with its
    disposition of portfolio securities;
 
        (3) Make loans, except through loans of portfolio securities or  through
    repurchase  agreements, provided that  for purposes of  this limitation, the
    acquisition of bonds, debentures, other  debt securities or instruments,  or
    participations  or  other interests  therein  and investments  in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (4) Purchase or sell physical commodities, but the Health Care Fund  may
    purchase, sell or enter into financial options and futures, forward and spot
    currency  contracts,  swap  transactions and  other  financial  contracts or
    derivative instruments;
 
        (5) Issue senior securities or  borrow money, except as permitted  under
    the  1940 Act and  then not in excess  of 33 1/3% of  the Health Care Fund's
    total assets (including the amount  borrowed but reduced by any  liabilities
    not  constituting borrowings) at the time  of the borrowing, except that the
    Health Care Fund may borrow up to an additional 5% of its total assets  (not
    including the amount borrowed) for temporary or emergency purposes; or
 
        (6)  Purchase securities of any one issuer if, as a result, more than 5%
    of the Health Care  Fund's total assets would  be invested in securities  of
    that  issuer or the Health Care Fund would  own or hold more than 10% of the
    outstanding voting securities of that issuer,  except that up to 25% of  the
    Health  Care  Fund's total  assets may  be invested  without regard  to this
    limitation, and except  that this  limitation does not  apply to  securities
    issued   or   guaranteed   by   the  U.S.   government,   its   agencies  or
    instrumentalities or to securities issued by other investment companies.
 
Notwithstanding any other investment policy of the Health Care Fund, the  Health
Care  Fund  may  invest  all  of its  investable  assets  (cash,  securities and
receivables related to securities) in an open-end management investment  company
having  substantially the same investment objective, policies and limitations as
the Fund.
 
The following investment policies  of the Health Care  Fund are not  fundamental
policies  and may be  changed by vote  of the Trust's  Board of Trustees without
shareholder approval. The Health Care Fund will not:
 
        (1) Purchase securities for which there is no readily available  market,
    or  enter into repurchase  agreements or purchase  time deposits maturing in
    more than seven days, or  purchase OTC options or  hold assets set aside  to
    cover  OTC options written by the Health Care Fund, if immediately after and
    as a result, the  value of such securities  would exceed, in the  aggregate,
    15% of the Health Care Fund's net assets;
 
        (2)  Purchase securities on  margin, provided that  the Health Care Fund
    may obtain  short-term credits  as may  be necessary  for the  clearance  of
    purchases and sales of securities, and further provided that the Health Care
    Fund  may  make margin  deposits  in connection  with  its use  of financial
    options and futures, forward and spot currency contracts, swap  transactions
    and other financial contracts or derivative instruments; or
 
        (3)  Mortgage, pledge, or  hypothecate any of  its assets, provided that
    this shall not apply  to the transfer of  securities in connection with  any
    permissible  borrowing  or  to collateral  arrangements  in  connection with
    permissible activities; or
 
        (4) Borrow money except for temporary or emergency purposes (other  than
    to  meet redemptions). While borrowings exceed  5% of the Health Care Fund's
    total assets, it will not make any additional investments.
 
Investors should  refer  to  the  Health  Care  Fund's  Prospectus  for  further
information  with respect to the Health  Care Fund's investment objective, which
may not  be  changed  without  the  approval  of  its  shareholders,  and  other

TELECOMMUNICATIONS FUND
The Telecommunications Fund has adopted the following investment limitations  as
fundamental  policies, which (unless otherwise noted) may not be changed without
approval by the affirmative vote of a majority of the outstanding shares of  the
Fund.
 
The Telecommunications Fund may not:
 
        (1)  Purchase or sell real estate, except that investments in securities
    of issuers that  invest in  real estate and  investments in  mortgage-backed
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    the Telecommunications Fund may exercise rights under agreements relating to
    such securities, including the  right to enforce  security interests and  to
    hold  real estate  acquired by  reason of  such enforcement  until that real
    estate can be liquidated in an orderly manner;
 
        (2) Purchase or  sell physical commodities,  but the  Telecommunications
    Fund may purchase, sell or enter into financial options and futures, forward
    and spot currency contracts, swap transactions and other financial contracts
    or derivative instruments;
 
        (3)  Engage in the business of underwriting securities of other issuers,
    except to the extent that the Telecommunications Fund might be considered an
    underwriter under  the  federal  securities  laws  in  connection  with  its
    disposition of portfolio securities;
 
        (4)  Make loans, except through loans of portfolio securities or through
    repurchase agreements, provided  that for purposes  of this limitation,  the
    acquisition  of bonds, debentures, other  debt securities or instruments, or
    participations or  other interests  therein  and investments  in  government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (5)  Issue senior securities or borrow  money, except as permitted under
    the 1940 Act and  then not in  excess of 33  1/3% of the  Telecommunications
    Fund's  total  assets  (including the  amount  borrowed but  reduced  by any
    liabilities not  constituting  borrowings) at  the  time of  the  borrowing,
    except that the Telecommunications Fund may borrow up to an additional 5% of
    its  total  assets  (not including  the  amount borrowed)  for  temporary or
    emergency purposes; or
 
        (6) Purchase securities of any one issuer if, as a result, more than  5%
    of   the  Telecommunications  Fund's  total  assets  would  be  invested  in
    securities of that issuer or the  Telecommunications Fund would own or  hold
    more  than 10% of  the outstanding voting securities  of that issuer, except
    that up to 25% of the Telecommunications Fund's total assets may be invested
    without regard to this limitation, and except that this limitation does  not
    apply  to  securities  issued  or guaranteed  by  the  U.S.  government, its
    agencies or instrumentalities  or to securities  issued by other  investment
    companies.
 
Notwithstanding  any other investment policy of the Telecommunications Fund, the
Telecommunications  Fund  may  invest  all  of  its  investable  assets   (cash,
securities  and  receivables related  to securities)  in an  open-end management
investment company having substantially the same investment objective,  policies
and limitations as the Fund.
 
The  following  investment  policies  of  the  Telecommunications  Fund  are not
fundamental policies and may be changed by vote of the Trust's Board of Trustees
without shareholder approval. The Telecommunications Fund may not:
 
        (1) Invest in securities of an issuer if the investment would cause  the
    Telecommunications  Fund to own more than 10%  of any class of securities of
    any one issuer;
 
        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;
 
        (3)  Invest  more than  15% of  its net  assets in  illiquid securities,
    including securities that are illiquid by virtue of the absence of a readily
    available market;
 
        (4) Enter into a futures contract,  an option on a futures contract,  or
    an  option on foreign currency traded  on a CFTC-regulated exchange, in each
    case other than for BONA FIDE hedging purposes (as defined by the CFTC),  if
    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5%  of  the liquidation  value of  the Fund's  portfolio, after  taking into
    account unrealized profits and unrealized  losses on any contracts the  Fund
    has entered into;
 
        (5)  Borrow money except for temporary or emergency purposes (other than
    to meet redemptions). While borrowings  exceed 5% of the  Telecommunications
    Fund's total assets, it will not make any additional investments;

                             AIM GLOBAL THEME FUNDS
 
        (6)  Purchase securities on margin, provided that the Telecommunications
    Fund may obtain short-term credits as may be necessary for the clearance  of
    purchases   and  sales  of   securities,  and  further   provided  that  the
    Telecommunications Fund may make margin deposits in connection with its  use
    of  financial options and futures, forward and spot currency contracts, swap
    transactions and other financial contracts or derivative instruments; or
 
        (7) Mortgage, pledge, or  hypothecate any of  its assets, provided  that
    this  shall not apply to  the transfer of securities  in connection with any
    permissible borrowing  or  to  collateral arrangements  in  connection  with
    permissible activities.
 
Investors  should refer to the  Telecommunications Fund's Prospectus for further
information with respect to the Telecommunications Fund's investment  objective,
which  may  not  be changed  without  the  approval of  shareholders,  and other
investment policies, techniques  and limitations, which  may be changed  without
shareholder approval.
 
If  a  percentage  restriction on  investment  or  utilization of  assets  in an
investment policy or  restriction is  adhered to at  the time  an investment  is
made, a later change in percentage ownership of a security or kind of securities
resulting  from changing market  values or a  similar type of  event will not be
considered a  violation  of  a  Fund's or  Portfolio's  investment  policies  or
restrictions.  A Fund or Portfolio  may exchange securities, exercise conversion
or subscription rights,  warrants or other  rights to purchase  common stock  or
other  equity securities and may hold, except  to the extent limited by the 1940
Act, any such securities so acquired without regard to the Fund's or Portfolio's
investment policies and  restrictions. The  original cost of  the securities  so
acquired  will  be  included in  any  subsequent  determination of  a  Fund's or
Portfolio's compliance with  the investment percentage  limitations referred  to
above and in the Prospectus.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
Subject  to policies  established by  the Trust's  and the  Portfolios' Board of
Trustees, the  Sub-adviser  is  responsible  for the  execution  of  each  Theme
Portfolio's  securities  transactions and  the  selection of  broker/dealers who
execute such  transactions  on behalf  of  each Theme  Portfolio.  In  executing
transactions,  the  Sub-adviser  seeks  the  best  net  results  for  each Theme
Portfolio, taking  into  account  such  factors  as  the  price  (including  the
applicable brokerage commission or dealer spread), size of the order, difficulty
of  execution  and operational  facilities of  the  firm involved.  Although the
Sub-adviser generally seeks reasonably competitive commission rates and spreads,
payment of the lowest  commission or spread is  not necessarily consistent  with
the  best net  results. While  each Theme  Portfolio may  engage in  soft dollar
arrangements for research services, as described below, it has no obligation  to
deal  with  any broker/dealer  or group  of broker/dealers  in the  execution of
portfolio transactions.
 
Consistent with  the interests  of  each Theme  Portfolio, the  Sub-adviser  may
select broker/dealers to execute that Theme Portfolio's portfolio transaction on
the basis of the research and brokerage services they provide to the Sub-adviser
for  its use in managing  that Theme Portfolio and  its other advisory accounts.
Such  services  may  include   furnishing  analyses,  reports  and   information
concerning issuers, industries, securities, geographic regions, economic factors
and  trends,  portfolio strategy,  and  performance of  accounts;  and effecting
securities transactions  and performing  functions incidental  thereto (such  as
clearance  and settlement). Research  and brokerage services  received from such
broker are in  addition to,  and not  in lieu of,  the services  required to  be
performed  by  the Sub-adviser  under the  applicable investment  management and
administration contract. A  commission paid to  such broker may  be higher  than
that  which another qualified  broker would have charged  for effecting the same
transaction, provided that the  Sub-adviser determines in  good faith that  such
commission  is reasonable in terms either  of that particular transaction or the
overall responsibility of the Sub-adviser to that Theme Portfolio and its  other
clients  and that  the total  commissions paid by  that Theme  Portfolio will be
reasonable in relation to the benefits it received over the long term.  Research
services may also be received from dealers who execute portfolio transactions in
OTC markets.
 
The  Sub-adviser may allocate brokerage  transactions to broker/dealers who have
entered into arrangements under which  the broker/dealer allocates a portion  of
the  commissions paid by a Theme Portfolio  toward payment of its expenses, such
as custodian fees.
 
Investment decisions for  a Theme  Portfolio and for  other investment  accounts
managed  by the  Sub-adviser are  made independently of  each other  in light of
differing conditions. However, the same investment decision occasionally may  be
 
                  Statement of Additional Information Page 25
<PAGE>
                             AIM GLOBAL THEME FUNDS
made  for two  or more of  such accounts,  including a Theme  Portfolio. In such
cases,  simultaneous  transactions  may  occur.  Purchases  or  sales  are  then
allocated  as to price  or amount in a  manner deemed fair  and equitable to all
accounts involved. While in  some cases this practice  could have a  detrimental
effect  upon the price or value  of the security as far  as a Theme Portfolio is
concerned, in other  cases the  Sub-adviser believes that  coordination and  the
ability  to participate in volume transactions  will be beneficial to that Theme
Portfolio.
 
Under a policy adopted by the Trust's and the Portfolios' Board of Trustees, and
subject to the  policy of obtaining  the best net  results, the Sub-adviser  may
consider  a broker/dealer's sale of the shares  of the Theme Funds and the other
portfolios for which  AIM or  the Sub-adviser  serves as  investment manager  or
administrator  in  selecting  broker/dealers  for  the  execution  of  portfolio
transactions. This  policy does  not  imply a  commitment to  execute  portfolio
transactions  through all broker/dealers that sell shares of the Theme Funds and
such other portfolios.
 
Each Theme Portfolio contemplates purchasing  most foreign equity securities  in
OTC  markets or stock exchanges located in the countries in which the respective
principal offices of the issuers of the various securities are located, if  that
is the best available market. The fixed commissions paid in connection with most
such foreign stock transactions generally are higher than negotiated commissions
on  U.S.  transactions.  There  generally  is  less  government  supervision and
regulation of foreign  stock exchanges and  brokers than in  the United  States.
Foreign  security settlements  may in  some instances  be subject  to delays and
related administrative uncertainties.
 
Foreign equity securities may be held by a Theme Portfolio in the form of  ADRs,
ADSs, EDRs, CDRs or securities convertible into foreign equity securities. ADRs,
ADSs,  EDRs and  CDRs may  be listed on  stock exchanges,  or traded  in the OTC
markets in the United  States or Europe,  as the case may  be. ADRs, like  other
securities traded in the United States, will be subject to negotiated commission
rates.  The foreign and domestic debt securities and money market instruments in
which a Theme Portfolio may invest are generally traded in the OTC markets.
 
A Theme Portfolio does not have any obligation to deal with any broker/dealer or
group of broker/dealers in the execution of securities transactions. Each  Theme
Portfolio  contemplates that, consistent  with the policy  of obtaining the best
net results, brokerage transactions may  be conducted through certain  companies
that  are affiliated with AIM or the Sub-adviser. The Trust's or the Portfolios'
Board of Trustees, as applicable, has adopted procedures in conformity with Rule
17e-1 under the 1940 Act to ensure  that all brokerage commissions paid to  such
affiliates  are reasonable and fair  in the context of  the market in which they
are operating. Any such transactions  will be effected and related  compensation
paid only in accordance with applicable SEC regulations.
 
For the fiscal years ended October 31, 1997, 1996 and 1995, the Health Care Fund
paid  aggregate brokerage  commissions of  $1,150,118, $1,619,500  and $545,743,
respectively. For the fiscal  years ended October 31,  1997, 1996 and 1995,  the
Telecommunications  Fund  paid  aggregate brokerage  commissions  of $2,254,069,
$2,848,733 and $2,253,982, respectively. For the fiscal years ended October  31,
1997,  1996 and 1995, the Financial  Services Portfolio paid aggregate brokerage
commissions of $250,893, $77,822 and $38,814, respectively. For the fiscal years
ended October  31,  1997,  1996  and 1995,  the  Infrastructure  Portfolio  paid
aggregate   brokerage   commissions   of   $131,543,   $124,164   and  $122,399,
respectively. For the fiscal  years ended October 31,  1997, 1996 and 1995,  the
Resources Portfolio paid aggregate brokerage commissions of $1,281,212, $496,370
and  $98,462, respectively. For the fiscal years ended October 31, 1997 and 1996
and for the  fiscal period  December 30,  1994 (commencement  of operations)  to
October  31, 1995, the  Consumer Products and  Services Portfolio paid aggregate
brokerage commissions of $1,454,348, $356,459 and $17,605, respectively. For the
fiscal years ended October 31,  1997 and 1996, the Health  Care Fund paid to  GT
Bank  in Liechtenstein AG, which was an "affiliated" broker, aggregate brokerage
commissions of  $23,081 and  $32,898, respectively,  for transactions  involving
purchases  and sales of portfolio securities  which represented 2.01% and 2.03%,
respectively, of the total  brokerage commissions paid by  the Health Care  Fund
and   1.61%  and  1.71%,  respectively,  of   the  aggregate  dollar  amount  of
transactions involving  payment of  commissions  by the  Health Care  Fund.  For
fiscal  year ended Octover 31, 1997, the Telecommunications Fund paid to GT Bank
in Liechtenstein,  AG, which  was an  "affiliated" broker,  aggregate  brokerage
commissions  of  $220,584  for  transactions involving  purchases  and  sales of
portfolio securities which represented 1.00% of the total brokerage  commissions
paid  by  the Fund  and  .67% of  the  aggregate dollar  amount  of transactions
involving payment of commissions by the Fund.
 
PORTFOLIO TRADING AND TURNOVER
Although each Theme Portfolio does not intend generally to trade for  short-term
profits,  the  securities held  by that  Theme Portfolio  will be  sold whenever
management believes it is appropriate to do so, without regard to the length  of
time  a  particular security  may  have been  held.  Portfolio turnover  rate is
calculated by dividing the lesser of sales or purchases of portfolio  securities
by   each  Theme  Portfolio's  average   month-end  portfolio  value,  excluding
short-term investments.  The portfolio  turnover  rate will  not be  a  limiting
factor   when   management   deems   portfolio   changes   appropriate.   Higher

portfolio turnover involves  correspondingly greater  brokerage commissions  and
other  transaction costs  that the Theme  Portfolio will bear  directly, and may
result in the realization of net capital gains that are taxable when distributed
to each Fund's  shareholders. For the  fiscal years ended  October 31, 1996  and
1997,  the Telecommunications Fund's portfolio turnover  rates were 37% and 35%,
respectively. For the fiscal years ended  October 31, 1996 and 1997, the  Health
Care  Fund's portfolio turnover rates were  157% and 149%, respectively. For the
fiscal years ended October 31, 1996  and 1997, the portfolio turnover rates  for
the   Financial  Services  Portfolio,  Infrastructure  Portfolio  and  Resources
Portfolio were 103% and 91%,  41% and 41%, and  94% and 321%, respectively.  For
the  fiscal years ended October 31, 1996  and 1997, the portfolio turnover rates
for  the  Consumer  Products  and   Services  Portfolio  were  169%  and   392%,
respectively.

company is paid aggregate  fees of $5,000  a year, plus $300  per Fund for  each
meeting  of the Board attended and reimbursed travel and other expenses incurred
in connection  with attendance  at such  meetings. Other  Trustees and  Officers

agreement between AIM and the Sub-adviser ("Portfolio Management  Sub-Contract,"
and  together with the Portfolio  Management Contract, the "Portfolio Management
Contracts").  AIM  serves  as  administrator  to  each  Feeder  Fund  under   an
administration  contract between the Trust  and AIM ("Administration Contract").
The Sub-adviser  serves  as  sub-administrator  to  each  Feeder  Fund  under  a
sub-administration  contract  between AIM  and the  Sub-adviser ("Administration
Sub-Contract,"   and   together   with   the   Administration   Contract,    the
"Administration  Contracts"). The  Administration Contracts  will not  be deemed
advisory contracts, as defined  under the 1940 Act.  As investment managers  and
administrators,  AIM and the Sub-adviser make  all investment decisions for each
Portfolio and, as  administrators, administer each  Portfolio's and each  Feeder
Fund's affairs. Among other things, AIM and the Sub-adviser furnish the services
and  pay  the  compensation  and  travel expenses  of  persons  who  perform the
executive, administrative, clerical and bookkeeping functions of each  Portfolio
and  each Feeder Fund and provide  suitable office space, necessary small office
equipment and utilities.
    
 
   
The Portfolio Management Contracts  may be renewed with  respect to a  Portfolio
for  additional  one-year  terms,  provided  that  any  such  renewal  has  been
specifically approved at least annually by (i) the Portfolios' Board of Trustees
or the vote of a majority  of the Portfolio's outstanding voting securities  (as
defined  in the 1940 Act) and (ii) a majority of Trustees who are not parties to
the Portfolio Management Contracts or "interested persons" of any such party (as
defined in the 1940 Act),  cast in person at a  meeting called for the  specific
purpose  of voting on such approval.  The Portfolio Management Contracts provide
that with respect to  each Portfolio, and  the Administration Contracts  provide
that  with respect to each Feeder Fund,  either the Trust, each Portfolio or the
Sub-adviser may terminate the Contracts without penalty upon sixty days' written
notice  to  the  other  party.  The  Portfolio  Management  Contracts  terminate
automatically in the event of their assignment (as defined in the 1940 Act).

Trust's  Board of Trustees, or by the vote of a majority of the Health Care Fund
and Telecommunications Fund's outstanding voting  securities (as defined in  the
1940 Act), and (ii) a majority of Trustees who are not parties to the Management
Contracts  or "interested  persons" of  any such party  (as defined  in the 1940
Act), cast in person at a meeting  called for the specific purpose of voting  on
such  approval. The Management Contracts provide that with respect to the Health
Care Fund and Telecommunications  Fund either the  Trust or each  of AIM or  the
Sub-adviser may terminate the Contracts without penalty upon sixty days' written
notice  to the other party. The  Management Contracts terminate automatically in

administration fees of  $18,756, $34,865  and $119,765;  $208,892, $218,735  and
$266,025;  and $74,485, $147,614  and $338,578, respectively.  However, the Sub-

and  $0; $177,376,  $0 and  $0; and  $74,485, $0  and $0,  respectively. For the

reimbursed  the  Consumer  Products   and  Services  Portfolio  for   investment
management  and  administration  fees  in  the amount  of  $16,284,  $0  and $0,
respectively. For the same periods, the Consumer Products and Services Fund paid
$5,933, $147,623 and  $416,297, respectively, in  administration fees;  however,
the  Sub-adviser  reimbursed the  Fund  in the  amounts  of $5,933,  $0  and $0,
respectively.
 
DISTRIBUTION SERVICES RELATING TO EACH FUND
   
Each Fund's Advisor Class  shares are offered  continuously through each  Fund's
principal  underwriter and  distributor, AIM  Distributors, on  a "best efforts"
basis pursuant to a distribution contract between the Trust and AIM Distributors
without a front-end sales charge or a contingent deferred sales charge.
    
 
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The Transfer Agency  and Service  Agreement between  the Trust  and A  I M  Fund
Services,  Inc. ("AFS"), a registered transfer agent and wholly-owned subsidiary
of AIM, provides  that AFS  will perform  certain shareholder  services for  the
Funds  for a fee per account serviced. The Transfer Agency and Service Agreement
provides that AFS will receive a per account fee plus out-of-pocket expenses  to
process  orders for purchases, redemptions and  exchanges of shares; prepare and
transmit payments  for  dividends  and  distributions  declared  by  the  Funds;
maintain   shareholder  accounts  and   provide  shareholders  with  information
regarding the  Funds  and  their  accounts.  The  Transfer  Agency  and  Service
Agreement  became effective on September 8, 1998. See "Additional Information --
Special Servicing Agreement." The Sub-adviser also serves as each Fund's pricing
and accounting agent. For the fiscal years ended October 31, 1995, 1996 and 1997
the accounting services fees for the Health Care Fund, Telecommunications  Fund,
Financial  Services  Fund,  Infrastructure  Fund,  Resources  Fund  and Consumer
Products and  Services  Fund  were $30,660,  $141,582  and  $153,780;  $170,297,
$621,480  and $493,322; $616, $3,493 and  $12,292 ; $5,836, $21,910 and $27,303;
$1,931, $14,761 and $34,698; and $318, $14,778 and $43,330, respectively.
    
 
EXPENSES OF THE FUNDS AND OF THE PORTFOLIOS
Each Fund  and  each  Portfolio  pays  all expenses  not  assumed  by  AIM,  the
Sub-adviser,  AIM  Distributors and  other  agents. These  expenses  include, in
addition to the advisory, administration, distribution, transfer agency, pricing
and accounting  agency  and brokerage  fees  described above,  legal  and  audit
expenses, custodian fees, trustees' fees, organizational fees, fidelity bond and
other  insurance premiums, taxes, extraordinary expenses and expenses of reports
and prospectuses sent to existing  investors. The allocation of general  Company
expenses and expenses shared among the Funds and other funds organized as series
of  the Company are allocated on a basis deemed fair and equitable, which may be
based on the  relative net  assets of  the Funds or  the nature  of the  service
performed and relative applicability to the Funds. Expenditures, including costs
incurred  in connection with the purchase or sale of portfolio securities, which
are capitalized  in accordance  with  generally accepted  accounting  principles
applicable  to investment companies, are accounted  for as capital items and not
as expenses. The ratio of each Fund's expenses to its relative net assets can be
expected to  be higher  than the  expense ratios  of funds  investing solely  in
domestic  securities,  since  the cost  of  maintaining the  custody  of foreign
securities and the rate of investment management  fees paid by the Funds or  the
Portfolios  generally  are higher  than the  comparable  expenses of  such other
funds.

                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
   
The net asset value per  share of each Fund is  normally determined daily as  of
the  close of trading  of the New  York Stock Exchange  ("NYSE") (generally 4:00
p.m. Eastern time)  on each  business day  of the Fund.  In the  event the  NYSE
closes  early (i.e., before 4:00 p.m. Eastern time) on a particular day, the net
asset value of a Fund is determined as of the close of the NYSE on such day. Net
asset value  per  share  is determined  by  dividing  the value  of  each  Theme
Portfolio's  securities, cash and  other assets (including  interest accrued but
not collected)  attributable to  a particular  class, less  all its  liabilities
(including  accrued expenses and dividends  payable) attributable to that class,
by the total number of shares  outstanding of that class. Determination of  each
Theme Portfolio's net asset value per share is made in accordance with generally
accepted accounting principles.
    
 
   
Each equity security held by a Theme Portfolio is valued at its last sales price
on  the exchange where the security is  principally traded or, lacking any sales
on a particular day, the security is valued at the mean between the closing  bid
and  asked  prices on  that day.  Each security  traded in  the over-the-counter
market (but  not including  securities reported  on the  NASDAQ National  Market
System)  is valued at the mean between the  last bid and asked prices based upon
quotes furnished by market makers for such securities. Each security reported on
the NASDAQ National  Market System  is valued  at the  last sales  price on  the
valuation date or absent a last sales price, at the mean between the closing bid
and  asked prices on that day. Debt securities are valued on the basis of prices
provided by  an independent  pricing  service. Prices  provided by  the  pricing
service  may be determined without exclusive  reliance on quoted prices, and may
reflect appropriate factors such as  institution-size trading in similar  groups
of  securities,  developments  related to  special  securities,  yield, quality,
coupon rate, maturity,  type of  issue, individual  trading characteristics  and
other  market  data.  Securities for  which  market quotations  are  not readily
available or are  questionable are valued  at fair value  as determined in  good
faith  by  or  under  the  supervision  of  the  Trust's  officers  in  a manner
specifically authorized by the Board of Trustees. Short-term obligations  having
60  days or  less to  maturity are valued  on the  basis of  amortized cost. For
purposes of determining net asset value per share, futures and options contracts
generally will be valued 15 minutes after the close of trading of the NYSE.
    
 
   
Generally, trading  in  foreign  securities, corporate  bonds,  U.S.  Government
securities  and money market instruments is  substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset  value of each Fund's  shares are determined at  such
times.  Foreign currency exchange rates are  also generally determined prior the
close of the NYSE. Occasionally, events affecting the values of such  securities
and  such exchange rates  may occur between  the times at  which such values are
determined and  the  close of  the  NYSE which  will  not be  reflected  in  the
computation  of a  Fund's net  asset value.  If events  materially affecting the
value of such securities occur during such period, then these securities will be
valued at  their  fair  value as  determined  in  good faith  by  or  under  the
supervision of the Board of Trustees of the Fund and the Portfolio.

Complete information concerning the method of exchanging shares of the Funds for
shares of the other AIM Funds is set forth in the Prospectuses under the heading
"Exchange Privilege."
    
 
   
Information concerning  redemption of  the Funds'  shares is  set forth  in  the
Prospectuses under the heading "How to Redeem Shares." In addition to the Funds'
obligation  to redeem shares, AIM Distributors  may also repurchase shares as an
accommodation to shareholders. To  effect a repurchase,  those dealers who  have
executed  Selected Dealer Agreements with AIM  Distributors must phone orders to
the order desk  of the Funds  at (800)  959-4246 and guarantee  delivery of  all
required  documents in  good order.  A repurchase is  effected at  the net asset
value per share  of the  applicable Fund  next determined  after the  repurchase
order  is received. Such  an arrangement is subject  to timely receipt  by A I M
Fund Services, Inc.,  the Funds' transfer  agent, of all  required documents  in
good  order. If such documents  are not received within  a reasonable time after
the order is placed,  the order is  subject to cancellation.  While there is  no
charge  imposed by  a Fund  or by  AIM Distributors  (other than  any applicable
contingent deferred  sales  charge) when  shares  are redeemed  or  repurchased,
dealers may charge a fair service fee for handling the transaction.
    
 
   
The  right of redemption may be suspended  or the date of payment postponed when
(a) trading on  the NYSE is  restricted, as determined  by applicable rules  and
regulations  of the SEC, (b) the NYSE is closed for other than customary weekend
and holiday closings, (c) the SEC has by order permitted such suspension, or (d)
an emergency as  determined by the  SEC exists making  disposition of  portfolio
securities  or  the  valuation  of  the net  assets  of  a  Fund  not reasonably
practicable.
    
 
   
A Fund's net  asset value is  calculated by dividing  the number of  outstanding
shares  into the net assets of  the Fund. Net assets are  the excess of a Fund's
assets over its liabilities. A more detailed description of how each Fund's  net
asset  value  is  calculated  appears  in  the  Prospectuses  under  the heading
"Determination of Net Asset Value."
    
 
   
PROGRAMS AND SERVICES FOR SHAREHOLDERS.  The Funds provide certain services  for
shareholders  and  certain  investment  or  redemption  programs.  See "Exchange
Privilege"  and  "How  to  Redeem  Shares"  in  the  Prospectus.  All  inquiries
concerning  these programs should be made directly to A I M Fund Services, Inc.,
P.O. Box 4739, Houston, Texas 77210-4739, toll free at (800) 959-4246.
    
 
   
DIVIDEND ORDER.  Dividends may  be paid  to someone  other than  the  registered
owner, or sent to an address other than the address of record. (Please note that
signature  guarantees are required to effect  this option.) An investor also may
direct that his or her dividends be invested  in one of the other AIM Funds  and
there  is no  sales charge  for these  investments; initial  investment minimums
apply.  See  "Dividends,  Distributions  and   Tax  Matters  --  Dividends   and
Distributions"  in the  Prospectus. To effect  this option,  please contact your
authorized dealer.  For more  information concerning  AIM Funds  other than  the
Funds,  please obtain a current prospectus by contacting your authorized dealer,

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUNDS
   
Each  Fund is treated as a separate corporation for federal income tax purposes.
To continue to qualify for treatment  as a regulated investment company  ("RIC")
under  the Code, each Fund must distribute  to its shareholders for each taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income, net short-term capital gain and net gains from certain
foreign  currency  transactions)  ("Distribution  Requirement")  and  must  meet
several  additional requirements. With respect  to each Fund, these requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each taxable year from dividends, interest, payments with respect to  securities
loans  and gains  from the  sale or other  disposition of  securities or foreign
currencies, or other income  (including gains from  options, Futures or  Forward
Contracts)  derived with respect  to its business of  investing in securities or
those  currencies   ("Income   Requirement");  and   (2)   the   Diversification
Requirements.  Each Feeder Fund, as an  investor in its corresponding Portfolio,
is deemed to own a proportionate share of the Portfolio's assets, and to earn  a
proportionate  share  of the  Portfolio's  income, for  purposes  of determining
whether the Fund satisfies the requirements described above to qualify as a RIC.
    
 
                  Statement of Additional Information Page 34
<PAGE>
                             AIM GLOBAL THEME FUNDS
 
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent it fails to distribute by the end of any calendar year substantially  all
of  its  ordinary income  for  that year  and capital  gain  net income  for the
one-year period ending on October 31 of that year, plus certain other amounts.
 
See the next section  for a discussion  of the tax  consequences to each  Feeder
Fund  of hedging  transactions engaged  in, and  investments in  passive foreign
investment  companies   ("PFICs")  and   other   foreign  securities,   by   its
corresponding  Portfolio and to the Health Care Fund and Telecommunications Fund
of those transactions and investments.
 
TAXATION OF THE THEME PORTFOLIOS
    THE PORTFOLIOS AND THEIR RELATIONSHIP TO THE FEEDER FUNDS. Each Portfolio is
treated as a separate partnership for federal  income tax purposes and is not  a
"publicly  traded partnership."  As a result,  each Portfolio is  not subject to
federal  income  tax;  instead,  each  Feeder  Fund,  as  an  investor  in   its
corresponding  Portfolio, is  required to take  into account  in determining its
federal income tax liability its share of the Portfolio's income, gains, losses,
deductions and  credits, without  regard to  whether it  has received  any  cash
distributions from the Portfolio. Each Portfolio also is not subject to Delaware
income or franchise tax.
 
Because, as noted above, each Feeder Fund is deemed to own a proportionate share
of  its corresponding Portfolio's  assets, and to earn  a proportionate share of
its corresponding Portfolio's  income, for purposes  of determining whether  the
Fund  satisfies the requirements to qualify as  a RIC, each Portfolio intends to
conduct its operations so that its  corresponding Fund will be able to  continue
to satisfy all those requirements.
 
Distributions  to  each Feeder  Fund from  its corresponding  Portfolio (whether
pursuant to a partial  or complete withdrawal or  otherwise) will not result  in
the  Fund's recognition  of any  gain or loss  for federal  income tax purposes,
except that  (1)  gain  will be  recognized  to  the extent  any  cash  that  is
distributed  exceeds the Fund's  basis for its interest  in the Portfolio before
the distribution, (2) income or gain  will be recognized if the distribution  is
in  liquidation of the  Fund's entire interest  in the Portfolio  and includes a
disproportionate share of any unrealized receivables held by the Portfolio,  and
(3)  loss will  be recognized if  a liquidation distribution  consists solely of
cash and/or unrealized receivables. Each Feeder Fund's basis for its interest in
its corresponding Portfolio  generally will  equal the  amount of  cash and  the
basis of any property the Fund invests in the Portfolio, increased by the Fund's
share of the Portfolio's net income and gains and decreased by (a) the amount of
cash and the basis of any property the Portfolio distributes to the Fund and (b)
the Fund's share of the Portfolio's losses.
 
    FOREIGN  TAXES. Dividends  and interest received  by a  Theme Portfolio, and
gains realized thereby,  may be subject  to income, withholding  or other  taxes
imposed  by foreign countries and U.S.  possessions ("foreign taxes") that would
reduce the yield and/or total return on its securities. Tax conventions  between
certain  countries and the United States  may reduce or eliminate foreign taxes,
however, and many  foreign countries  do not impose  taxes on  capital gains  in
respect  of investments by foreign investors. If more than 50% of the value of a
Fund's total assets  (taking into account,  in the  case of a  Feeder Fund,  its
proportionate share of its corresponding Portfolio's assets) at the close of its
taxable  year consists of  securities of foreign corporations,  the Fund will be
eligible to, and may,  file an election with  the Internal Revenue Service  that
will  enable its shareholders, in effect, to  receive the benefit of the foreign
tax credit with respect to any foreign taxes paid by it (taking into account, in
the case of a Feeder Fund, its proportionate share of any foreign taxes paid  by
its  corresponding  Portfolio)  (a  "Fund's  foreign  taxes").  Pursuant  to the
election, a Fund would treat those  taxes as dividends paid to its  shareholders
and each shareholder would be required to (1) include in gross income, and treat
as  paid by him, his share  of the Fund's foreign taxes,  (2) treat his share of
those taxes and of any dividend paid by the Fund that represents its income from
foreign and U.S.  possessions sources  (taking into account,  in the  case of  a
Feeder  Fund, its  proportionate share  of its  corresponding Portfolio's Income
from those sources) as his own income  from those sources and (3) either  deduct
the  taxes deemed paid by him in computing his taxable income or, alternatively,
use the foregoing information in calculating the foreign tax credit against  his
federal income tax. Each Fund will report to its shareholders shortly after each
taxable  year their  respective shares  of the  Fund's foreign  taxes and income
(taking into account, in the case of  a Feeder Fund, its proportionate share  of
its  corresponding Portfolio's income) from sources within foreign countries and
U.S. possessions if it makes this election. Pursuant to the Taxpayer Relief  Act
of  1997 ("Tax Act"), individuals  who have no more  than $300 ($600 for married
persons filing jointly) of  creditable foreign taxes included  on Form 1099  and
all  of whose foreign source  of income is "qualified  passive income" may elect
each year  to  be exempt  from  the  extremely complicated  foreign  tax  credit
limitation and will be able to claim a foreign tax credit without having to file
the detailed Form 1116 that otherwise is required.
 
    PASSIVE FOREIGN INVESTMENT COMPANIES. Each Theme Portfolio may invest in the
stock  of PFICs.  A PFIC is  a foreign  corporation -- other  than a "controlled
foreign corporation" (I.E., a  foreign corporation in which,  on any day  during
its  taxable year, more than  50% of the total voting  power of all voting stock
therein or the total value of  all stock therein is owned, directly,  indirectly
or  constructively,  by  "U.S.  shareholders,"  defined  as  U.S.  persons  that
individually own,
 
                  Statement of Additional Information Page 35
<PAGE>
                             AIM GLOBAL THEME FUNDS
   
directly, indirectly or constructively, at least 10% of that voting power) as to
which the Theme Portfolio is a U.S. shareholder (effective with respect to  each
Fund  for their taxable  year beginning November  1, 1998) --  that, in general,
meets either of the  following tests: (1)  at least 75% of  its gross income  is
passive or (2) an average of at least 50% of its assets produce, or are held for
the  production of, passive income. Under  certain circumstances, a Fund will be
subject to federal income tax on a part  (or, in the case of a Feeder Fund,  its
proportionate  share of a part) of any "excess distribution" received by it (or,
in the case of a Feeder Fund, by its corresponding Portfolio) on the stock of  a
PFIC  or of  any gain  on the  Fund's (or,  in the  case of  a Feeder  Fund, its
corresponding  Portfolio's)  disposition  of  that  stock  (collectively   "PFIC
income"), plus interest thereon, even if the Fund distributes the PFIC income as
a  taxable dividend to its shareholders. The  balance of the PFIC income will be
included in the Fund's investment company taxable income and, accordingly,  will
not  be  taxable  to  it  to  the  extent  it  distributes  that  income  to its
shareholders.
    
 
If a  Theme Portfolio  invests in  a PFIC  and elects  to treat  the PFIC  as  a
"qualified  electing  fund"  ("QEF"), then  in  lieu  of the  foregoing  tax and
interest obligation, the Theme  Portfolio (or, in the  case of a Portfolio,  its
corresponding  Feeder Fund) would be required to include in income each year its
pro rata  share  (taking  into account,  in  the  case of  a  Feeder  Fund,  its
proportionate  share of  its corresponding  Portfolio's pro  rata share)  of the
QEF's annual ordinary  earnings and net  capital gain (I.E.,  the excess of  net
long-term  capital gain over  net short-term capital loss)  -- which most likely
would have  to be  distributed by  the Theme  Portfolio (or,  in the  case of  a
Portfolio,   its  corresponding   Feeder  Fund)  to   satisfy  the  Distribution
Requirement and avoid imposition of the Excise Tax -- even if those earnings and
gain were not received thereby from the  QEF. In most instances it will be  very
difficult,  if  not  impossible,  to  make  this  election  because  of  certain
requirements thereof.
 
A holder of stock in any PFIC may  elect to include in ordinary income for  each
taxable  year beginning after 1997, the excess, if any, of the fair market value
of the  stock over  the adjusted  basis  therein as  of the  end of  that  year.
Pursuant  to the election, a deduction (as  an ordinary, not capital, loss) also
will be allowed for the excess, if  any, of the holder's adjusted basis in  PFIC
stock over the fair market value thereof as of the taxable year-end, but only to
the  extent of any net mark-to-market gains  with respect to that stock included
in income  for prior  taxable years.  The adjusted  basis in  each PFIC's  stock
subject  to  the election  will be  adjusted  to reflect  the amounts  of income
included and deductions taken thereunder. Regulations proposed in 1992  provided
a similar election with respect to the stock of certain PFICs.
 
    OPTIONS,  FUTURES AND  FOREIGN CURRENCY TRANSACTIONS.  The Theme Portfolios'
use of hedging transactions,  such as selling  (writing) and purchasing  options
and  Futures  Contracts and  entering into  Forward Contracts,  involves complex
rules that  will  determine,  for  federal  income  tax  purposes,  the  amount,
character  and timing of recognition  of the gains and  losses a Theme Portfolio
realizes in connection therewith. Gains  from disposition of foreign  currencies
(except  certain gains  that may be  excluded by future  regulations), and gains
from the options,  Futures and Forward  Contracts derived by  a Theme  Portfolio
with  respect to its business of  investing in securities or foreign currencies,
will qualify as permissible income under  the Income Requirement for that  Theme
Portfolio (or, in the case of a Portfolio, its corresponding Feeder Fund).
 
   
Futures  and Forward  Contracts that  are subject  to section  1256 of  the Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts")  and that are  held by a Theme  Portfolio at the  end of its taxable
year generally will be deemed to have been sold at that time at market value for
federal income tax purposes. Sixty percent of any net gain or loss recognized on
these deemed sales, and  60% of any  net gain or loss  realized from any  actual
sales  of Section 1256 Contracts,  will be treated as  long-term capital gain or
loss, and the balance will be treated  as short-term capital gain or loss.  That
60%  portion will  qualify for  the reduced  maximum tax  rates on non-corporate
taxpayers' net capital gain enacted by the Tax Act -- 20% (10% for taxpayers  in
the  15% marginal tax  bracket) for gain  recognized on capital  assets held for
more than  18  months  --  instead  of  the  28%  rate  in  effect  before  that
legislation,  which now  applies to gain  recognized on capital  assets held for
more than one year but not more than 18 months.
    
 
Section 988 of the Code also may apply to gains and losses from transactions  in
foreign  currencies, foreign-currency-denominated  debt securities  and options,
Futures and Forward  Contracts on  foreign currencies ("Section  988" gains  and
losses).  Each Section  988 gain  or loss  generally is  computed separately and
treated as ordinary income or loss. In the case of overlap between sections 1256
and 988, special provisions  determine the character and  timing of any  income,
gain  or loss. Each Theme Portfolio attempts to monitor section 988 transactions
to minimize any adverse tax impact.
 
If a Theme Portfolio  has an "appreciated financial  position" -- generally,  an
interest  (including an interest through an  option, Futures or Forward Contract
or short sale) with respect to any stock, debt instrument (other than  "straight
debt")  or  partnership interest  the  fair market  value  of which  exceeds its
adjusted basis  --  and  enters  into  a "constructive  sale"  of  the  same  or
substantially  similar property, the  Theme Portfolio will  be treated as having
made an actual sale  thereof, with the  result that gain  will be recognized  at
that time. A constructive sale generally consists of a short sale, an offsetting
notional  principal contract  or Futures or  Forward Contract entered  into by a
Theme Portfolio or a  related person with respect  to the same or  substantially
similar property. In addition, if the appreciated financial position is itself a
short sale
 
                  Statement of Additional Information Page 36
<PAGE>
                             AIM GLOBAL THEME FUNDS
or  such a  contract, acquisition  of the  underlying property  or substantially
similar property will be deemed a constructive sale.
 
TAXATION OF THE FUNDS' SHAREHOLDERS
Dividends and  other  distributions  declared  by a  Fund  in,  and  payable  to
shareholders  of record as  of a date  in, October, November  or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during  the following  January. Accordingly,  those distributions  will  be
taxed to shareholders for the year in which that December 31 falls.
 
   
If  Fund shares are sold at a loss after  being held for six months or less, the
loss will be treated  as long-term, instead of  short-term, capital loss to  the
extent  of any  capital gain distributions  received on  those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or other distribution, the shareholder will pay full price  for
the shares and receive some portion of the price back as a taxable distribution.
    
 
Dividends  paid by a  Fund to a shareholder  who, as to the  United States, is a
nonresident alien individual, nonresident alien fiduciary of a trust or  estate,
foreign  corporation  or foreign  partnership ("foreign  shareholder") generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply, however, to a  dividend paid by a Fund to a  foreign
shareholder  that is "effectively connected with the  conduct of a U.S. trade or
business," in which case the  reporting and withholding requirements  applicable
to  domestic shareholders will  apply. A distribution  of net capital  gain by a
Fund to a foreign shareholder generally  will be subject to U.S. federal  income
tax  (at the rates applicable  to domestic persons) only  if the distribution is
"effectively connected"  or the  foreign shareholder  is treated  as a  resident
alien individual for federal income tax purposes.
 
The  foregoing  is a  general  and abbreviated  summary  of certain  federal tax
considerations affecting  the  Funds,  their shareholders  and  the  Portfolios.
Investors  are  urged  to  consult  their own  tax  advisers  for  more detailed
information and for  information regarding  any foreign, state  and local  taxes
applicable to distributions received from a Fund.

AIM  was organized in 1976, and along  with its subsidiaries, manages or advises
approximately 90 investment  company portfolios  encompassing a  broad range  of
investment  objectives.  AIM is  a  direct, wholly  owned  subsidiary of  A  I M
Management Group  Inc.  ("AIM Management"),  a  holding company  that  has  been
engaged  in  the  financial  services  business  since  1976.  AIM  is  the sole
shareholder  of  the  Funds'   principal  underwriter,  AIM  Distributors.   AIM
Management is an indirect wholly owned subsidiary of AMVESCAP PLC, 11 Devonshire
Square,  London, EC2M  4YR, England.  AMVESCAP PLC  and its  subsidiaries are an
independent investment management group that  has a significant presence in  the
institutional  and retail segment of the investment management industry in North
America and Europe, and a growing presence in Asia.
 
CUSTODIAN
State Street  Bank and  Trust  Company ("State  Street"), 225  Franklin  Street,
Boston,  Massachusetts  02110,  acts  as  custodian  of  the  Funds'  and  Theme
Portfolios' assets. State Street is authorized to establish and has  established
separate  accounts in  foreign currencies and  to cause securities  of the Theme
Portfolios to be  held in  separate accounts outside  the United  States in  the
custody of non-U.S. banks.
 
INDEPENDENT ACCOUNTANTS
   
The    Trust's    and    Theme   Portfolios'    independent    accountants   are
                        , conducts  annual audits  of  the Portfolios'  and  the
Funds'  financial statements, assists in the preparation of each Portfolio's and
each Fund's federal and state income tax returns and consults with the Trust and
Global Investment Portfolio as to matters of accounting, regulatory filings, and
federal and state income taxation.
    
 
   
The audited financial  statements of  the Trust  included in  this Statement  of
Additional Information have been examined by                         , as stated
in  their  opinion appearing  herein,  and are  included  in reliance  upon such
opinion given  upon the  authority of  that firm  as experts  in accounting  and
auditing.
    
 
   
SHAREHOLDER LIABILITY
    
   
Under  Delaware law,  the shareholders of  the Trust enjoy  the same limitations
extended to shareholders of private, for-profit corporations. There is a  remote
possibility, however, that under certain circumstances shareholders of the Trust
may  be held personally  liable for the Trust's  obligations. However, the Trust
Agreement disclaims shareholder liability for  acts or obligations of the  Trust
and  requires  that  notice  of  such disclaimer  be  given  in  each agreement,
obligation or instrument entered into or executed by the Trust or a trustee. The
Trust Agreement provides  for indemnification  from the Trust  property for  all
losses  and expenses of  any shareholder held personally  liable for the Trust's
obligations. Thus, the risk of a shareholder incurring financial loss on account
of such liability is limited to circumstances in which the Trust itself would be
unable to meet  its obligations and  where the other  party was held  not to  be
bound by the disclaimer.
    
 
NAMES
Prior  to May 29, 1998, AIM Global  Consumer Products and Services Fund operated

SPECIAL SERVICING AGREEMENT
   
Subject to receipt of an exemptive order from the SEC, the Funds will be parties
to a Special Servicing Agreement ("Agreement") among the Trust on behalf of  the
Funds,  AIM Series Trust  on behalf of  its sole series,  AIM Global Trends Fund
("Global Trends  Fund"),  AIM, the  Sub-adviser,  and AFS.  The  Agreement  will
provide  that, if the  Board of Trustees  determines that a  Fund's share of the
aggregate expenses of Global Trends Fund  is less than the estimated savings  to
the  Fund from  the operation of  Global Trends  Fund, the Fund  will bear those
expenses in proportion to the average daily value of its shares owned by  Global
Trends  Fund, provided  that no Fund  will bear  such expenses in  excess of the
estimated savings to it. Those savings are expected to result primarily from the
elimination of numerous separate  shareholder accounts which  are or would  have
been  invested directly in the Funds  and the resulting reduction in shareholder
servicing costs.  Although such  cost  savings are  not certain,  the  estimated
savings  to  the Funds  generated by  the  operation of  Global Trends  Fund are
expected to be sufficient to offset most,  if not all, of the expenses  incurred
by that Fund.

TOTAL RETURN QUOTATIONS
The  standard  formula  for  calculating  total  return,  as  described  in  the
Prospectus, is as follows:
 
                                 P(1+T)(n)=ERV
 
<TABLE>
<S>        <C>        <C>
Where      P   =      a hypothetical initial payment of $1,000.
           T   =      average annual total return  (assuming the applicable maximum  sales load is deducted  at
                      the beginning of the 1, 5, or 10 year periods.)
           n   =      number of years.
           ERV =      ending  redeemable value of a hypothetical  $1,000 payment at the end  of the 1, 5, or 10
                      year periods (or fractional portion of such period).

                      applicable maximum sales load at the beginning of the stated period.
           n   =      number of years.
           ERV =      ending redeemable value of a hypothetical $1,000 payment at the end of the stated period.

                      applicable maximum sales load at the beginning of the stated period.
           n   =      number of years.

Each Fund's investment results will vary from time to time depending upon market
conditions, the composition of each  Fund's portfolio and operating expenses  of
each  Fund,  so  that  current or  past  yield  or total  return  should  not be
considered representative of  what an investment  in each Fund  may earn in  any
future  period. These  factors and possible  differences in the  methods used in
calculating investment results should be  considered when comparing each  Fund's
investment results with those published for other investment companies and other
investment  vehicles. Each Fund's results also  should be considered relative to
the risks associated with such Fund's investment objective and policies.

for  any  of the  Funds  may disclose  (i) the  largest  holdings in  the Fund's
portfolio, (ii) certain selling group members and/or (iii) certain institutional
shareholders.
 
From time to time, the Funds' sales literature and/or advertisements may discuss
generic topics pertaining to the mutual fund industry. This includes, but is not
limited to,  literature  addressing  general  information  about  mutual  funds,
variable   annuities,  dollar-cost  averaging,  stocks,  bonds,  money  markets,
certificates  of  deposit,  retirement,  retirement  plans,  asset   allocation,
tax-free investing, college planning, and inflation.
 
Although  performance data may be useful to prospective investors when comparing
a Fund's performance with other funds and other potential investments, investors
should note  that  the  methods  of computing  performance  of  other  potential
investments are not necessarily comparable to the methods employed by a Fund.
 
GENERAL INFORMATION ABOUT THE THEME FUNDS AND THEME PORTFOLIOS
Each Theme Portfolio may invest worldwide across industries within the Portfolio
area  of concentration without national or regional restrictions. The ability of
each Theme Portfolio  to invest worldwide  may allow the  portfolio managers  to
select   industries  in  different   economic  cycles  and   varying  stages  of
development, though there is no assurance  that the managers will be  successful
in this selection.
 
Each  Theme Portfolio's area  of concentration reflects  the underlying theme of
the  Portfolio.  AIM  Distributors  believes  that  there  are  certain  social,
political  and economic trends that may benefit  one or more industries within a
Theme Portfolio's area of concentration. Of  course, there is no assurance  that
any of the Funds will benefit as a result.

From time to time the Fund and AIM Distributors will quote information including
data regarding:
 
    / / Trading  volume, number of listed companies and the largest companies of
        the global health care industry
 
    / / Expenditures by various countries, regions and age groups on health care
 
    / / Population of countries, regions and age groups

The information quoted  has not  been independently verified  by a  Fund or  AIM
Distributors  and will be based on data provided that is believed to be reliable
and accurate from sources including the following:
 
    / / Research firms such  as Mehta and  Isaly which publishes  PHARMACEUTICAL
        PORTFOLIO RECOMMENDATIONS
 
    / / OECD  and its publications such as the OECD HEALTH DATA, as supplemented

        REPORT, as supplemented annually
 
    / / IFC and publications such as the EMERGING STOCK MARKETS FACTBOOK
 
INFORMATION ABOUT THE GLOBAL HEALTH CARE INDUSTRIES
The Fund and the Sub-adviser believe that certain market and demographic factors
merit  an  investor's  consideration  when  making  a  health  care  investment.
Worldwide   standards  of  living  and  life  expectancy  have  increased  at  a
substantial rate.  The  Sub-adviser expects  this  growth, which  works  to  the
general  benefit of the  global health care  industry, to continue  at a roughly
comparable rate  in the  future, although  no assurances  can be  given in  this
regard.  Moreover,  according  to  the  Sub-adviser,  the  health  care industry
historically has proven to be a relatively non-cyclical industry that  continues
to  provide goods and services to the  public in periods of economic weakness as
well as economic strength.
 
The Sub-adviser believes that  the anticipated increase  in the world's  elderly
population  could increase  demand for  health care  products and  services. For
example, according to data compiled by  the Sub-adviser, in Japan the number  of
people  age 65  and older is  expected to  grow over 100%  by the  year 2025; in
Germany, France and the U.S., the same age group

<PAGE>
                             AIM GLOBAL THEME FUNDS
should grow  40%. Similarly,  the  U.S. Census  Bureau  predicts the  number  of
Americans  85 and older to double  in the next 30 years.  From time to time, the
Fund and AIM Distributors will quote information including, but not limited  to,
international  data regarding  populations, birth  rates, mortality  rates, life
expectancy, health  care  expenditures,  and gross  domestic  product  vs.  life
expectancy.  The information quoted  has not been  independently verified by the
Fund or  AIM Distributors  and will  be based  on data  that is  believed to  be
reliable and accurate.
 
TELECOMMUNICATIONS FUND
From time to time the Fund and AIM Distributors will quote information including
data regarding:
 
    / / Increased  usage  of  new  technologies such  as,  but  not  limited to,
        cellular  and  wireless  communications  in  emerging  and   established
        countries around the world
 
    / / Supply and demand of telephone equipment and services
 
    / / Regulatory environment of telecommunications industries
 
    / / Revenue, price and usage of telecommunications products and services
 
    / / Privatization and/or deregulation of telecommunications companies
 
The  information quoted has not  been independently verified by  the Fund or AIM
Distributors and will be based on data provided that is believed to be  reliable
and accurate from sources including the following:
 
    / / Salomon  Brothers World Equity  Telecommunications Index, which includes
        stock market data about  the telecommunications industry in  established
        and developing markets
 
    / / OECD   and  other  publications  from   its  subsidiaries  such  as  the
        International Telecommunications Union
 
    / / Morgan Stanley Capital International stock market industry indices  such
        as  Telecommunications, Broadcasting & Publishing  and Data Processing &
        Reproduction
 
    / / International Technology Consultants, a Washington D.C. based firm which
        publishes reports such as EASTERN  EUROPEAN & SOVIET TELECOM REPORT  and
        LATIN AMERICAN TELECOM REPORT
 
    / / Telegeography and other publications
 
DEREGULATION IN THE UNITED STATES
The  United States  has been  the bellwether  for deregulation  of the telephone
industry. The  divestiture  of  the  Bell System  from  American  Telephone  and
Telegraph  has  produced competing  companies in  the  United States.  Such U.S.
market-driven competition has,  for example,  led to lower  costs for  consumers
which in turn led to greater consumer usage and to higher industrywide revenues.
The  Sub-adviser expects this scenario to  continue to benefit such companies in
the U.S.  and similarly  to be  realized by  the established  telecommunications
companies  in established economies, although no  assurances can be made in this
regard.
 
CONSUMER PRODUCTS AND SERVICES FUND
From time to time the Fund and AIM Distributors will quote information including

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. ("Moody's") rates the debt securities issued
by various entities from  "Aaa" to "C." Investment  grade ratings are the  first
four categories:
 
        Aaa  -- Bonds which are rated Aaa are  judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt  edged." Interest payments  are protected  by a large  or by  an
    exceptionally  stable  margin and  principal  is secure.  While  the various
    protective elements are likely to change, such changes as can be  visualized
    are  most  unlikely  to impair  the  fundamentally strong  position  of such
    issues.
 
        Aa -- Bonds which are rated Aa are  judged to be of high quality by  all
    standards.  Together with  the Aaa  group they  comprise what  are generally
    known as high grade bonds. They are rated lower than the best bonds  because
    margins  of  protection  may  not  be  as  large  as  in  Aaa  securities or
    fluctuation of protective elements may be of greater
 
                  Statement of Additional Information Page 45
<PAGE>
                             AIM GLOBAL THEME FUNDS
    amplitude or there may  be other elements present  which make the  long-term
    risk appear somewhat larger than the Aaa securities.
 
        A  --  Bonds  which  are  rated  A  possess  many  favorable  investment
    attributes and  are  to  be considered  as  upper-medium-grade  obligations.
    Factors  giving security to principal  and interest are considered adequate,
    but elements may  be present  which suggest a  susceptibility to  impairment
    some time in the future.
 
        Baa  --  Bonds  which  are  rated  Baa  are  considered  as medium-grade
    obligations, (i.e., they are neither  highly protected nor poorly  secured).
    Interest payments and principal security appear adequate for the present but
    certain  protective  elements may  be lacking  or may  be characteristically
    unreliable over  any  great length  of  time. Such  bonds  lack  outstanding
    investment  characteristics and in fact  have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative  elements;
    their  future  cannot be  considered well-assured.  Often the  protection of
    interest and principal payments may be  very moderate, and thereby not  well
    safeguarded  during both good and bad  times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B --  Bonds which  are rated  B generally  lack characteristics  of  the
    desirable  investment. Assurance  of interest  and principal  payments or of
    maintenance of other terms of the contract over any long period of time  may
    be small.
 
        Caa  -- Bonds which are rated Caa  are of poor standing. Such issues may
    be in default or  there may be  present elements of  danger with respect  to
    principal or interest. --_>
 
        Ca   ]  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are  rated C are the lowest  rated class of bonds,  and
    issues  so rated can be regarded as  having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has  been
suspended  or withdrawn, it may  be for reasons unrelated  to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
         1. An application for rating was not received or accepted.
 
         2. The issue or  issuer belongs to a  group of securities or  companies
    that are not rated as a matter of policy.
 
         3. There is a lack of essential data pertaining to the issue or issuer.
 
         4.  The issue  was privately  placed, in which  case the  rating is not
    published in Moody's publications.
 
Suspension or withdrawal may occur if new and material circumstances arise,  the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable  up-to-date data  to permit  a judgment  to be  formed; if  a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies  numerical modifiers, 1,  2 and 3  in each generic  rating
classification  from Aa to Caa. The modifier  1 indicates that the Company ranks
in the higher end  of its generic  rating category; the  modifier 2 indicates  a
mid-range  ranking; and the modifier  3 indicates that the  Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a  division of The  McGraw-Hill Companies, Inc.  ("S&P"),
rates  the securities debt of various  entities in categories ranging from "AAA"
to "D"  according  to quality.  Investment  grade  ratings are  the  first  four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA   --  An  obligation  rated  "AA"  differs  from  the  highest  rated
    obligations only  in a  small degree.  The obligor's  capacity to  meet  its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB   --  An   obligation  rated  "BBB"   exhibits  adequate  protection
    parameters. However, adverse economic  conditions or changing  circumstances
    are  more likely to lead  to a weakened capacity of  the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and  "C"
    are   regarded  as  having  significant  speculative  characteristics.  "BB"
    indicates the least degree  of speculation and "C"  the highest. While  such
    obligations
 
                  Statement of Additional Information Page 46
<PAGE>
                             AIM GLOBAL THEME FUNDS
    will  likely have some quality and  protective characteristics, these may be
    outweighed by large uncertainties or major exposures to adverse conditions.
 
        BB -- An  obligation rated "BB"  is less vulnerable  to nonpayment  than
    other  speculative issues. However, it  faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which  could
    lead  to the obligor's inadequate capacity  to meet its financial commitment
    on the obligation.
 
        B --  An obligation  rated "B"  is more  vulnerable to  nonpayment  than
    obligations  rated "BB," but the obligor  currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial,  or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC  -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its  financial commitment on the obligation. In  the
    event of adverse business, financial, or economic conditions, the obligor is
    not  likely to  have the  capacity to meet  its financial  commitment on the
    obligation.
 
        CC --  An  obligation  rated  "CC" is  currently  highly  vulnerable  to
    nonpayment.
 
        C  -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed  or similar action has  been taken, but payments  on
    this obligation are being continued.
 
        D  -- An  obligation rated  "D" is  in payment  default. The  "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the  applicable grace period  has not expired,  unless S&P  believes
    that  such payments will  be made during  such grace period.  The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking  of
    a similar action if payments on an obligation are jeopardized.
 
PLUS  (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by the
addition of a  plus or minus  sign to  show relative standing  within the  major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient information on which to base a rating, or that S&P does not rate  a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S  employs  the  designation "Prime-1"  to  indicate  commercial paper
having a superior ability for  repayment of senior short-term debt  obligations.
Prime-1  repayment  ability will  often be  evidenced by  many of  the following
characteristics: leading market positions  in well-established industries;  high
rates  of return on  funds employed; conservative  capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in  earnings
coverage  of  fixed financial  charges and  high  internal cash  generation; and
well-established access to a range of  financial markets and assured sources  of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior  short-term debt obligations. This normally  will be evidenced by many of
the characteristics cited  above but  to a  lesser degree.  Earnings trends  and
coverage  ratios, while sound, may be  more subject to variation. Capitalization
characteristics, while  still  appropriate, may  be  more affected  by  external
conditions. Ample alternate liquidity is maintained.
 
    S&P  ratings of commercial paper are  graded into several categories ranging
from "A1" for the highest quality obligations  to "D" for the lowest. Issues  in
the  "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate the
relative degree  of safety.  A-1 --  This highest  category indicates  that  the
degree  of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation.  A-2  -- Capacity  for  timely  payments on  issues  with  this
designation  is satisfactory; however,  the relative degree of  safety is not as

                                  INTRODUCTION
    
 
- --------------------------------------------------------------------------------
 
   
This Statement of Additional Information relates to the Advisor Class shares of
AIM Global Government Income Fund ("Government Income Fund"), AIM Strategic
Income Fund ("Strategic Income Fund"), AIM Global High Income Fund ("High Income
Fund"), and AIM Global Growth & Income Fund ("Growth & Income Fund") (each, a
"Fund," and collectively, the "Funds"). Each Fund is a non-diversified series of
AIM Investment Funds (the "Company"), a registered open-end management
investment company organized as a Delaware business trust. The High Income Fund
invests all its investable assets in AIM Global High Income Portfolio
("Portfolio").
    
 
   
A I M Advisors, Inc. ("AIM") serves as the investment manager of and
administrator for, and INVESCO (NY), Inc. (the "Sub-adviser") serves as the
investment sub-adviser and sub-administrator for the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund and the Global High Income
Portfolio (the "Portfolio"). AIM and the Sub-adviser also serve as the
administrator and sub-administrator, respectively, of the High Income Fund.
    
 
   
The Trust is a series mutual fund. The rules and regulations of the United
States Securities and Exchange Commission (the "SEC") require all mutual funds
to furnish prospective investors certain information concerning the activities
of the fund being considered for investment. This information for Government
Income Fund is included in a Prospectus dated September 8, 1998, for Strategic
Income Fund is included in a separate Prospectus dated September 8, 1998, for
High Income Fund is included in a separate Prospectus dated September 8, 1998,
and for Growth & Income Fund is included in a separate Prospectus dated
September 8, 1998. Additional copies of the Prospectuses and this Statement of
Additional Information may be obtained without charge by writing the principal
distributor of the Funds' shares, A I M Distributors, Inc. ("AIM Distributors"),
P.O. Box 4739, Houston, TX 77210-4739 or by calling (800) 347-4246. Investors
must receive a Prospectus before they invest.
    
 
   
This Statement of Additional Information is intended to furnish prospective
investors with additional information concerning the Funds. Some of the
information required to be in this Statement of Additional Information is also
included in the Prospectus; and, in order to avoid repetition, reference will be
made to sections of the Prospectus. Additionally, the Prospectus and this
Statement of Additional Information omit certain information contained in the
Registration Statement filed with the SEC. Copies of the Registration Statement,
including items omitted from the Prospectus and this Statement of Additional
Information, may be obtained from the SEC by paying the charges prescribed under
its rules and regulations.
    
 
   
                      GENERAL INFORMATION ABOUT THE FUNDS
    
 
   
THE TRUST AND ITS SHARES
    
   
The Trust previously operated under the name G.T. Investment Funds, Inc., which
was organized as a Maryland corporation on October 29, 1987. The Trust was
reorganized on May 29, 1998 as a Delaware business trust, and is registered with
the SEC as a diversified open-end series management investment company. The
Trust currently consists of thirteen separate portfolios: each of the six Theme
Funds, AIM Global Government Income Fund, AIM Global High Income Fund, AIM
Strategic Income Fund, AIM Global Growth and Income Fund, AIM Emerging Markets
Fund, AIM Developing Markets Fund, and AIM Latin American Growth Fund. Each of
these funds has three separate classes: Class A, Class B and Advisor Class
shares. All historical financial and other information contained in this
Statement of Additional Information for periods prior to May 29, 1998, is that
of the series G.T. Investment Funds, Inc.
    
 
   
This Statement of Additional Information relates solely to the Advisor Class
shares of the Funds.
    
 
   
The term "majority of the outstanding shares" of the Trust, a particular Fund,
or a particular class of a Fund means, respectively, the vote of the lesser of
(a) 67% or more of the shares of the Trust, such Fund or such class present at a
meeting

                       AIM GLOBAL GOVERNMENT INCOME FUND
                           AIM STRATEGIC INCOME FUND

                        AIM GLOBAL GROWTH & INCOME FUND
   
of the Trust's shareholders, if the holders of more than 50% of the outstanding
shares of the Trust, such Fund or such class are present or represented by
proxy, or (b) more than 50% of the outstanding shares of the Trust, such Fund or
such class.
    
 
   
Class A, and Class B and Advisor Class shares of each Fund have equal rights and
privileges. Each share of a particular class is entitled to one vote, to
participate equally in dividends and distributions declared by the Trust's Board
of Trustees with respect to the class of such Fund and, upon liquidation of the
Fund, to participate proportionately in the net assets of the Fund allocable to
such class remaining after satisfaction of outstanding liabilities of the Fund
allocable to such class. Fund shares are fully paid, non-assessable and fully
transferable when issued and have no preemptive rights and have such conversion
and exchange rights as set forth in the Prospectus and this Statement of
Additional Information. Fractional shares have proportionately the same rights,
including voting rights, as are provided for a full share.
    
 
   
Shareholders of the Funds do not have cumulative voting rights, and therefore
the holders of more than 50% of the outstanding shares of all Funds voting
together for election of directors may elect all of the members of the Board of
Trustees of the Trust. In such event, the remaining holders cannot elect any
trustees of the Trust.

                       INVESTMENT OBJECTIVES AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES
   
The Government Income Fund primarily seeks high current income and secondarily
seeks capital appreciation and protection of principal through active management
of the maturity structure and currency exposure of its portfolio. The Strategic
Income Fund and the High Income Fund primarily seek high current income and
secondarily seek capital appreciation. The High Income Fund seeks to achieve its
investment objectives by investing all of its investable assets in the
Portfolio, which is a non-diversified open-end management investment company
with investment objectives identical to those of the Fund. Whenever the phrase
"all of the High Income Fund's investable assets" is used herein and in the
Prospectus, it means that the only investment securities held by the High Income
Fund will be its interest in the Portfolio. The High Income Fund may withdraw
its investment in the Portfolio at any time, if the Board of Trustees of the
Trust determines that it is in the best interests of the Fund and its
shareholders to do so. Upon any such withdrawal, the High Income Fund's assets
would be invested in accordance with the investment policies of the Portfolio
described below and in the Prospectus. The investment objective of the Growth &
Income Fund is long-term capital appreciation together with current income. The
Growth & Income Fund seeks its objective by investing in a global portfolio of
both equity securities and debt obligations allocated among diverse
international markets.
    
 
INVESTMENT IN EMERGING MARKETS
The Portfolio seeks its objectives by investing, under normal circumstances, at
least 65% of its total assets in debt securities of issuers in emerging markets.
The Strategic Income Fund may invest up to 50% of its assets in debt securities
of issuers in emerging markets. The Strategic Income Fund and the Portfolio do
not consider the following countries to be emerging markets: Australia, Austria,
Belgium, Canada, Denmark, France, Germany, Ireland, Italy, Japan, the
Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland, United Kingdom,
and United States.
 
In addition to the factors set forth in the Prospectus, the Sub-adviser will
also consider, when determining what countries constitute emerging markets,
data, analysis, and classification of countries published or disseminated by the
International Bank for Reconstruction and Development (commonly known as the
World Bank) and the International Finance Corporation.
 
SELECTION OF DEBT INVESTMENTS
   
In determining the appropriate distribution of investments among various
countries and geographic regions for the Government Income Fund, the Strategic
Income Fund, the Growth & Income Fund, and the Portfolio, the Sub-adviser
ordinarily considers the following factors: prospects for relative economic
growth among the different countries in which the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund, and the Portfolio may invest;
    
 
                   Statement of Additional Information Page 4
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
                           AIM STRATEGIC INCOME FUND
                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
expected levels of inflation; government policies influencing business
conditions; the outlook for currency relationships; and the range of the
individual investment opportunities available to international investors.
 
The Government Income Fund, the Strategic Income Fund and the Portfolio may
invest in the following types of money market instruments (i.e., debt
instruments with less than 12 months remaining until maturity) denominated in
U.S. dollars or other currencies: (a) obligations issued or guaranteed by the
U.S. or foreign governments, their agencies, instrumentalities or
municipalities; (b) obligations of international organizations designed or
supported by multiple foreign governmental entities to promote economic
reconstruction or development; (c) finance company obligations, corporate
commercial paper and other short-term commercial obligations: (d) bank
obligations (including certificates of deposit, time deposits, demand deposits
and bankers' acceptances), subject to the restriction that the Government Income
Fund, the Strategic Income Fund and the Portfolio may not invest more than 25%
of their respective total assets in bank securities; (e) repurchase agreements
with respect to the foregoing; and (f) other substantially similar short-term
debt securities with comparable characteristics. Money market instruments in
which the Growth & Income Fund may invest include U.S. government securities,
high-grade commercial paper, bank certificates of deposit, bankers' acceptances
and repurchase agreements related to any of the foregoing. "High-grade
commercial paper" refers to commercial paper rated A-1 by Standard & Poor's, a
division of The McGraw-Hill Companies, Inc. ("S&P"), or P-1 by Moody's Investors
Service, Inc. ("Moody's") or, if not rated, determined by the Sub-adviser to be
of comparable quality.
 
SELECTION OF EQUITY INVESTMENTS
With respect to Growth & Income Fund, for investment purposes, an issuer is
typically considered as located in a particular country if it (a) is
incorporated under the laws of or has its principal office in that country, or
(b) it normally derives 50% or more of its total revenue from business in that
country. However, these are not absolute requirements, and certain companies
incorporated in a particular country and considered by the Sub-adviser to be
located in that country may have substantial off-shore operations or
subsidiaries and/or export sales exceeding in size the assets or sales in that
country.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
With respect to certain countries, investments by the Government Income Fund,
the Strategic Income Fund, the Growth & Income Fund and the Portfolio presently
may be made only by acquiring shares of other investment companies (including
investment vehicles or companies advised by the Sub-adviser or its affiliates
("Affiliated Funds")) with local governmental approval to invest in those
countries. At such time as direct investment in these countries is allowed, the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio anticipate investing directly in these markets. The Government
Income Fund, the Strategic Income Fund, the Growth & Income Fund and the
Portfolio may also invest in the securities of closed-end investment companies
within the limits of the Investment Company Act of 1940, as amended ("1940
Act"). These limitations currently provide that, in part, a Fund or the
Portfolio may purchase shares of another investment company unless (a) such a
purchase would cause the Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund or the Portfolio to own in the aggregate more than 3% of
the total outstanding voting securities of the investment company or (b) such a
purchase would cause the Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund or the Portfolio to have more than 5% of its total assets
invested in the investment company or more than 10% of its aggregate assets
invested in an aggregate of all such investment companies. The foregoing
limitations do not apply to the investment by the High Income Fund in the
Portfolio. Investment in investment companies may involve the payment of
substantial premiums above the value of such companies' portfolio securities.
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio do not intend to invest in such investment companies unless,
in the judgment of the Sub-adviser, the potential benefits of such investments
justify the payment of any applicable premiums. The return on such securities
will be reduced by operating expenses of such companies including payments to
the investment managers of those investment companies. With respect to
investments in Affiliated Funds, the Sub-adviser waives its advisory fee to the
extent that such fees are based on assets of a Fund invested in Affiliated
Funds.
 
   
DEPOSITARY RECEIPTS
    
   
The Growth & Income Fund may hold equity securities of foreign issuers in the
form of American Depositary Receipts ("ADRs"), American Depositary Shares
("ADSs"), Global Depositary Receipts ("GDRs") and European Depositary Receipts
("EDRs"), or other securities convertible into securities of eligible issuers.
These securities may not necessarily be denominated in the same currency as the
securities for which they may be exchanged. ADRs and ADSs typically are issued
by an American bank or trust company and evidence ownership of underlying
securities issued by a foreign corporation. EDRs, which are sometimes referred
to as Continental Depositary Receipts ("CDRs"), are issued in Europe typically
by
    
 
                   Statement of Additional Information Page 5
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
                           AIM STRATEGIC INCOME FUND
                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
foreign banks and trust companies and evidence ownership of either foreign or
domestic securities. GDRs are similar to EDRs and are designed for use in
several international financial markets. Generally, ADRs and ADSs in registered
form are designed for use in United States securities markets and EDRs in bearer
form are designed for use in European securities markets. For purposes of the
Fund's investment policies, the Fund's investments in ADRs, ADSs, GDRs and EDRs
will be deemed to be investments in the equity securities representing
securities of foreign issuers into which they may be converted.
 
ADR facilities may be established as either "unsponsored" or "sponsored." While
ADRs issued under these two types of facilities are in some respects similar,
there are distinctions between them relating to the rights and obligations of
ADR holders and the practices of market participants. A depository may establish
an unsponsored facility without participation by (or even necessarily the
acquiescence of) the issuer of the deposited securities, although typically the
depository requests a letter of non-objection from such issuer prior to the
establishment of the facility. Holders of unsponsored ADRs generally bear all
the costs of such facilities. The depository usually charges fees upon the
deposit and withdrawal of the deposited securities, the conversion of dividends
into U.S. dollars, the disposition of non-cash distributions, and the
performance of other services. The depository of an unsponsored facility
frequently is under no obligation to distribute shareholder communications
received from the issuer of the deposited securities or to pass-through voting
rights to ADR holders in respect of the deposited securities. Sponsored ADR
facilities are created in generally the same manner as unsponsored facilities,
except that the issuer of the deposited securities enters into a deposit
agreement with the depository. The deposit agreement sets out the rights and
responsibilities of the issuer, the depository and the ADR holders. With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository), although ADR holders continue to bear certain other costs (such as
deposit and withdrawal fees). Under the terms of most sponsored arrangements,
depositories agree to distribute notices of shareholder meetings and voting
instructions, and to provide shareholder communications and other information to
the ADR holders at the request of the issuer of the deposited securities. The
Fund may invest in both sponsored and unsponsored ADRs.
 
SAMURAI AND YANKEE BONDS
The Government Income Fund, the Strategic Income Fund and the Portfolio may
invest in yen-denominated bonds sold in Japan by non-Japanese issuers ("Samurai
bonds"), and may invest in dollar-denominated bonds sold in the United States by
non-U.S. issuers ("Yankee bonds"). It is the policy of the Government Income
Fund, the Strategic Income Fund and the Portfolio to invest in Samurai or Yankee
bond issues only after taking into account considerations of quality and
liquidity, as well as yield.
 
WARRANTS OR RIGHTS
Warrants or rights may be acquired by the Government Income Fund, the Strategic
Income Fund, the Growth & Income Fund or the Portfolio in connection with other
securities or separately and provide a Fund or the Portfolio with the right to
purchase at a later date other securities of the issuer.
 
LENDING OF PORTFOLIO SECURITIES
   
For the purpose of realizing additional income, the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund or the Portfolio may make
secured loans of portfolio securities amounting to not more than 30% of its
total assets. Securities loans are made to broker/dealers or institutional
investors pursuant to agreements requiring that the loans continuously be
secured by collateral at least equal at all times to the value of the securities
lent plus any accrued interest, "marked to market" on a daily basis. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund, and
the Portfolio may pay reasonable administrative and custodial fees in connection
with loans of its securities. While the securities loan is outstanding, the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio will continue to receive the equivalent of the interest or
dividends paid by the issuer on the securities, as well as interest on the
investment of the collateral or a fee from the borrower. The Government Income
Fund, the Strategic Income Fund, the Growth & Income Fund and the Portfolio each
will have a right to call each loan and obtain the securities within the stated
settlement period. The Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund and the Portfolio will not have the right to vote equity
securities while they are lent, but each may call in a loan in anticipation of
any important vote. Loans will be made only to firms deemed by the Sub-adviser
to be of good standing and will not be made unless, in the judgment of the
Sub-adviser, the consideration to be earned from such loans would justify the
risk.

                        AIM GLOBAL GROWTH & INCOME FUND
 
COMMERCIAL BANK OBLIGATIONS
   
For the purposes of the Strategic Income Fund's, the Growth & Income Fund's and
the Portfolio's investment policies with respect to bank obligations,
obligations of foreign branches of U.S. banks and of foreign banks are
obligations of the issuing bank and may be general obligations of the parent
bank. Such obligations, however, may be limited by the terms of a specific
obligation and by government regulation. As with investment in non-U.S.
securities in general, investments in the obligations of foreign branches of
U.S. banks and of foreign banks may subject the Strategic Income Fund, the
Growth & Income Fund and the Portfolio to investment risks that are different in
some respects from those of investments in obligations of domestic issuers.
Although the Strategic Income Fund, the Growth & Income Fund and the Portfolio
typically will acquire obligations issued and supported by the credit of U.S. or
foreign banks having total assets at the time of purchase in excess of $1
billion, this $1 billion figure is not an investment policy or restriction of
the Strategic Income Fund, the Growth & Income Funds or the Portfolio. For the
purposes of calculation with respect to the $1 billion figure, the assets of a
bank will be deemed to include the assets of its U.S. and non-U.S. branches.
    
 
REPURCHASE AGREEMENTS
   
A repurchase agreement is a transaction in which the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund, or the Portfolio buys a
security from a bank or recognized securities dealer and simultaneously commits
to resell that security to the bank or dealer at an agreed upon price, date and
market rate of interest unrelated to the coupon rate or maturity of the
purchased security. Although repurchase agreements carry certain risks not
associated with direct investments in securities, including possible decline in
the market value of the underlying securities and delays and costs to the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund or
Portfolio if the other party to the repurchase agreement becomes bankrupt, the
Government Income Fund, the Strategic Income Fund, Growth & Income Fund and the
Portfolio intend to enter into repurchase agreements only with banks and
broker/dealers believed by the Sub-adviser to present minimal credit risks in
accordance with guidelines approved by the Board of Trustees. The Sub-adviser
reviews and monitors the creditworthiness of such institutions under the Board's
general supervision.
    
 
   
The Government Income Fund, the Strategic Income Fund, Growth & Income Fund and
the Portfolio will invest only in repurchase agreements collateralized at all
times in an amount at least equal to the repurchase price plus accrued interest.
There is no limitation on the amount of the Growth & Income Fund's assets that
may be subject to repurchase agreements at any time. To the extent that the
proceeds from any sale of such collateral upon a default in the obligation to
repurchase were less than the repurchase price, the Government Income Fund, the
Strategic Income Fund, Growth & Income Fund or the Portfolio would suffer a
loss. If the financial institution which is party to the repurchase agreement
petitions for bankruptcy or otherwise becomes subject to bankruptcy or other
liquidation proceedings there may be restrictions on the Government Income Fund,
the Strategic Income Fund, the Growth & Income Fund's or the Portfolio's ability
to sell the collateral and the Government Income Fund, the Strategic Income
Fund, Growth & Income Fund or the Portfolio could suffer a loss. However, with
respect to financial institutions whose bankruptcy or liquidation proceedings
are subject to the U.S. Bankruptcy Code, the Government Income Fund, the
Strategic Income Fund Growth & Income Fund and the Portfolio intend to comply
with provisions under such Code that would allow the immediate resale of such
collateral. The Government Income Fund and the Growth & Income Fund will not
enter into a repurchase agreement with a maturity of more than seven days if, as
a result, more than 10% of the value of each Fund's total assets would be
invested in such repurchase agreements and other illiquid investments and
securities for which no readily available market exists.
    
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
   
The Government Income Fund's, the Strategic Income Fund's, the Growth & Income
Fund's and the Portfolio's borrowings will not exceed 33 1/3% of the Fund's or
the Portfolio's respective total assets, i.e., the Government Income Fund's, the
Strategic Income Fund's, the Growth & Income Fund's and the Portfolio's
respective total assets at all times will equal at least 300% of the amount of
its outstanding borrowings. If market fluctuations in the value of the
Government Income Fund's, the Strategic Income Fund's, the Growth & Income
Fund's or the Portfolio's total assets to outstanding borrowings to fall below
300%, within three days (excluding Sundays and holidays) of such event the
respective Fund or the Portfolio may be required to sell portfolio securities to
restore the 300% asset coverage, even though from an investment standpoint such
sales might be disadvantageous. The Government Income Fund, the Strategic Income
Fund, the Growth & Income Fund and the Portfolio each may borrow up to 5% of its
respective total assets for temporary or emergency purposes other than to meet
redemptions. Any borrowing by the Government Income Fund, the Strategic Income
Fund, the Growth & Income Fund or the Portfolio may cause greater fluctuation in
the value of its shares than would be the case if the Fund or the Portfolio did
not borrow.

The Government Income Fund's, the Strategic Income Fund's, the Growth & Income
Fund's and the Portfolio's fundamental investment limitations permit them to
borrow money for leveraging purposes. The Government Income Fund and the Growth
& Income Fund, however, currently are prohibited, pursuant to a non-fundamental
investment policy, from borrowing money in order to purchase securities.
Nevertheless, this policy may be changed in the future by a vote of a majority
of the Trust's Board of Trustees. The Strategic Income Fund and the Portfolio
may borrow for leveraging purposes. If the Strategic Income Fund or the
Portfolio employs leverage, it would be subject to certain additional risks. Use
of leverage creates an opportunity for greater growth of capital but would
exaggerate any increases or decreases in the Strategic Income Fund's or the
Portfolio's net asset value. When the income and gains on securities purchased
with the proceeds of borrowings exceed the costs of such borrowings, the
Government Income Fund's, the Strategic Income Fund's, the Growth & Income
Fund's or the Portfolio's earnings or net asset value will increase faster than
otherwise would be the case; conversely, if such income and gains fail to exceed
such costs, the Fund's or the Portfolio's earnings or net asset value would
decline faster than would otherwise be the case.
    
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio may enter into reverse repurchase agreements. A reverse
repurchase agreement is a borrowing transaction in which a Fund or the Portfolio
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price, which includes an interest component. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio also may engage in "roll" borrowing transactions which involve a
Fund's or the Portfolio's sale of Government National Mortgage Association
certificates or other securities together with a commitment (for which a Fund or
the Portfolio may receive a fee) to purchase similar, but not identical,
securities at a future date. The Government Income Fund, the Strategic Income
Fund, the Growth & Income Fund and the Portfolio will segregate with a
custodian, cash or liquid securities in an amount sufficient to cover its
obligations under "roll" transactions and reverse repurchase agreements with
broker/dealers. No segregation is required for reverse repurchase agreements
with banks.
 
SHORT SALES
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio may make short sales of securities, although they have no
current intention of doing so. A short sale is a transaction in which a Fund or
the Portfolio sells a security in anticipation that the market price of that
security will decline. The Government Income Fund, the Strategic Income Fund,
the Growth & Income Fund and the Portfolio may make short sales as a form of
hedging to offset potential declines in long positions in securities it owns, or
anticipates acquiring, and in order to maintain portfolio flexibility. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio only may make short sales "against the box." In this type of short
sale, at the time of the sale, the Fund or the Portfolio owns the security it
has sold short or has the immediate and unconditional right to acquire the
identical security at no additional cost.
 
In a short sale, the seller does not immediately deliver the securities sold and
does not receive the proceeds from the sale. To make delivery to the purchaser,
the executing broker borrows the securities being sold short on behalf of the
seller. The seller is said to have a short position in the securities sold until
it delivers the securities sold, at which time it receives the proceeds of the
sale. To secure its obligation to deliver securities sold short, the Government
Income Fund, the Strategic Income Fund, the Growth & Income Fund or the
Portfolio will deposit in a separate account with its custodian an equal amount
of the securities sold short or securities convertible into or exchangeable for
such securities at no cost. The Government Income Fund, the Strategic Income
Fund, the Growth & Income Fund or the Portfolio could close out a short position
by purchasing and delivering an equal amount of the securities sold short,
rather than by delivering securities already held by the Fund or the Portfolio,
because the Fund or the Portfolio might want to continue to receive interest and
dividend payments on securities in its portfolio that are convertible into the
securities sold short.
 
   
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio might make a short sale "against the box" in order to hedge
against market risks when the Sub-adviser believes that the price of a security
may decline, causing a decline in the value of a security owned by the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund or
the Portfolio or a security convertible into or exchangeable for such security.
In such case, any future losses in the Government Income Fund's, the Strategic
Income Fund's, the Growth & Income Fund's or the Portfolio's long position
should be reduced by a gain in the short position. Conversely, any gain in the
long position should be reduced by a loss in the short position. The extent to
which such gains or losses in the long position are reduced will depend upon the
amount of the securities sold short relative to the amount of the securities the
Fund or the Portfolio owns, either directly or indirectly, and, in the case
where a Fund or the Portfolio owns convertible securities,

                        AIM GLOBAL GROWTH & INCOME FUND
changes in the investment values or conversion premiums of such securities.
There will be certain additional transaction costs associated with short sales
"against the box," but a Fund or the Portfolio will endeavor to offset these
costs with income from the investment of the cash proceeds of short sales.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The use of options, futures contracts and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1) Successful use of most of these instruments depends upon the
    Sub-adviser's ability to predict movements of the overall securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Sub-adviser is experienced in
    the use of these instruments, there can be no assurance that any particular
    strategy adopted will succeed.
 
        (2) There might be imperfect correlation, or even no correlation,
    between price movements of an instrument and price movements of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge increased by less than the decline in value of the hedged
    investment, the hedge would not be fully successful. Such a lack of
    correlation might occur due to factors unrelated to the value of the
    investments being hedged, such as speculative or other pressures on the
    markets in which the hedging instrument is traded. The effectiveness of
    hedges using hedging instruments on indices will depend on the degree of
    correlation between price movements in the index and price movements in the
    investments being hedged.
 
   
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by offsetting the positive effect of favorable price
    movements in the hedged investments. For example, if the Government Income
    Fund, the Strategic Income Fund, the Growth & Income Fund or the Portfolio
    entered into a short hedge because the Sub-adviser projected a decline in
    the price of a security in the Fund's or the Portfolio's portfolio, and the
    price of that security increased instead, the gain from that increase might
    by wholly or partially offset by a decline in the price of the hedging
    instrument. Moreover, if the price of the hedging instrument declined by
    more than the increase in the price of the security, the Government Income
    Fund, the Strategic Income Fund, the Growth & Income Fund or the Portfolio
    could suffer a loss. In either such case, the Government Income Fund, the
    Strategic Income Fund, the Growth & Income Fund or the Portfolio would have
    been in a better position had it not hedged at all.
    
 
   
        (4) As described below, the Government Income Fund, the Strategic Income
    Fund, the Growth & Income Fund or the Portfolio might be required to
    maintain assets as "cover," maintain segregated accounts or make margin
    payments when it takes positions in instruments involving obligations to
    third parties (I.E., instruments other than purchased options). If a Fund or
    the Portfolio were unable to close out its positions in such instruments, it
    might be required to continue to maintain such assets or accounts or make
    such payments until the position expired or matured. The requirements might
    impair the Fund's ability or the Portfolio's ability to sell a portfolio
    security or make an investment at a time when it would otherwise be
    favorable to do so, or require that the Fund or the Portfolio sell a
    portfolio security at a disadvantageous time. The Fund's or the Portfolio's
    ability to close out a position in an instrument prior to expiration or
    maturity depends on the existence of a liquid secondary market or, in the
    absence of such a market, the ability and willingness of the other party to
    the transaction ("contra party") to enter into a transaction closing out the
    position. Therefore, there is no assurance that any position can be closed
    out at a time and price that is favorable to the Fund or the Portfolio.
    
 
WRITING CALL OPTIONS
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio may write (sell) call options on securities, indices and
currencies. Call options generally will be written on securities and currencies
that, in
 
                   Statement of Additional Information Page 9
<PAGE>
                       AIM GLOBAL GOVERNMENT INCOME FUND
                           AIM STRATEGIC INCOME FUND
                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
the opinion of the Sub-adviser are not expected to make any major price moves in
the near future but that, over the long term, are deemed to be attractive
investments for the Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund and the Portfolio.
 
A call option gives the holder (buyer) the right to purchase a security or
currency at a specified price (the exercise price) at any time until (American
Style) or on (European Style) a certain date (the expiration date). So long as
the obligation of the writer of a call option continues, he may be assigned an
exercise notice, requiring him to deliver the underlying security or currency
against payment of the exercise price. This obligation terminates upon the
expiration of the call option, or such earlier time at which the writer effects
a closing purchase transaction by purchasing an option identical to that
previously sold.
 
Portfolio securities or currencies on which call options may be written will be
purchased solely on the basis of investment considerations consistent with a
Fund's or the Portfolio's investment objectives. When writing a call option, the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund or
the Portfolio, in return for the premium, gives up the opportunity for profit
from a price increase in the underlying security or currency above the exercise
price, and retains the risk of loss should the price of the security or currency
decline. Unlike one who owns securities or currencies not subject to an option,
a Fund or the Portfolio has no control over when it may be required to sell the
underlying securities or currencies, since most options may be exercised at any
time prior to the option's expiration. If a call option that a Fund or the
Portfolio has written expires, the Fund or the Portfolio will realize a gain in
the amount of the premium; however, such gain may be offset by a decline in the
market value of the underlying security or currency during the option period. If
the call option is exercised, the Fund or the Portfolio will realize a gain or
loss from the sale of the underlying security or currency, which will be
increased or offset by the premium received. The Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund and the Portfolio do not
consider a security or currency covered by a call option to be "pledged" as that
term is used in the Government Income Fund's, the Strategic Income Fund's, the
Growth & Income Fund's and the Portfolio's fundamental investment policies that
limit the pledging or mortgaging of their assets.
 
Writing call options can serve as a limited short hedge because declines in the
value of the hedged investment would be offset to the extent of the premium
received for writing the option. However, if the security or currency
appreciates to a price higher than the exercise price of the call option, it can
be expected that the option will be exercised and a Fund or the Portfolio will
be obligated to sell the security or currency at less than its market value.
 
The premium that the Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund or the Portfolio receives for writing a call option is
deemed to constitute the market value of an option. The premium a Fund or the
Portfolio will receive from writing a call option will reflect, among other
things, the current market price of the underlying investment, the relationship
of the exercise price to such market price, the historical price volatility of
the underlying investment, and the length of the option period. In determining
whether a particular call option should be written, the Sub-adviser will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing transactions will be effected in order to realize a profit on an
outstanding call option, to prevent an underlying security or currency from
being called, or to permit the sale of the underlying security or currency.
Furthermore, effecting a closing transaction will permit the Government Income
Fund, the Strategic Income Fund, the Growth & Income Fund or the Portfolio to
write another call option on the underlying security or currency with either a
different exercise price, expiration date or both.
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio will pay transaction costs in connection with the writing of
options and in entering into closing purchase contracts. Transaction costs
relating to options activity normally are higher than those applicable to
purchases and sales of portfolio securities.
 
The exercise price of the options may be below, equal to or above the current
market values of the underlying securities or currencies at the time the options
are written. From time to time, a Fund or the Portfolio may purchase an
underlying security or currency for delivery in accordance with the exercise of
an option, rather than delivering such security or currency from its portfolio.
In such cases, additional costs will be incurred.
 
A Fund or the Portfolio will realize a profit or loss from a closing purchase
transaction if the cost of the transaction is less or more, respectively, than
the premium received from writing the option. Because increases in the market
price of a call option generally will reflect increases in the market price of
the underlying security or currency, any loss resulting from the

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
repurchase of a call option is likely to be offset in whole or in part by
appreciation of the underlying security or currency owned by a Fund or the
Portfolio.
 
WRITING PUT OPTIONS
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio may write put options on securities, indices and currencies. A
put option gives the purchaser of the option the right to sell, and the writer
(seller) the obligation to buy, the underlying security or currency at the
exercise price at anytime until (American Style) or on (European Style) the
expiration date. The operation of put options in other respects, including their
related risks and rewards, is substantially identical to that of call options.
 
A Fund or the Portfolio generally would write put options in circumstances where
the Sub-adviser wishes to purchase the underlying security or currency for the
Fund's or the Portfolio's portfolio at a price lower than the current market
price of the security or currency. In such event, the Fund or the Portfolio
would write a put option at an exercise price that, reduced by the premium
received on the option, reflects the lower price it is willing to pay. Since the
Fund or the Portfolio also would receive interest on debt securities or
currencies maintained to cover the exercise price of the option, this technique
could be used to enhance current return during periods of market uncertainty.
The risk in such a transaction would be that the market price of the underlying
security or currency would decline below the exercise price less the premium
received.
 
Writing put options can serve as a limited long hedge because increases in the
value of the hedged investment would be offset to the extent of the premium
received for writing the option. However, if the security or currency
depreciates to a price lower than the exercise price of the put option, it can
be expected that the put option will be exercised and a Fund or the Portfolio
will be obligated to purchase the security or currency at greater than its
market value.
 
PURCHASING PUT OPTIONS
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio may purchase put options on securities, indices and
currencies. As the holder of a put option, the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund or the Portfolio would have the
right to sell the underlying security or currency at the exercise price at any
time until (American Style or on (European Style) the expiration date. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund or
the Portfolio may enter into closing sale transactions with respect to such
options, exercise them or permit them to expire.
 
A Fund or the Portfolio may purchase a put option on an underlying security or
currency ("protective put") owned by the Fund or the Portfolio as a hedging
technique in order to protect against an anticipated decline in the value of the
security or currency. Such hedge protection is provided only during the life of
the put option when the Fund or the Portfolio, as the holder of the put option,
is able to sell the underlying security or currency at the put exercise price
regardless of any decline in the underlying security's market price or
currency's exchange value. The premium paid for the put option and any
transaction costs would reduce any profit otherwise available for distribution
when the security or currency eventually is sold.
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio also may purchase put options at a time when that Fund or the
Portfolio does not own the underlying security or currency. By purchasing put
options on a security or currency it does not own, a Fund or the Portfolio seeks
to benefit from a decline in the market price of the underlying security or
currency. If the put option is not sold when it has remaining value, and if the
market price of the underlying security or currency remains equal to or greater
than the exercise price during the life of the put option, the Fund or the
Portfolio will lose its entire investment in the put option. In order for the
purchase of a put option to be profitable, the market price of the underlying
security or currency must decline sufficiently below the exercise price to cover
the premium and transaction costs, unless the put option is sold in a closing
sale transaction.
 
PURCHASING CALL OPTIONS
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
or the Portfolio may purchase call options on securities, indices and
currencies. As the holder of a call option, a Fund or the Portfolio would have
the right to purchase the underlying security or currency at the exercise price
at any time until (American Style) or on (European Style) the expiration date. A
Fund or the Portfolio may enter into closing sale transactions with respect to
such options, exercise them or permit them to expire.
 
Call options may be purchased by a Fund or the Portfolio for the purpose of
acquiring the underlying security or currency for its portfolio. Utilized in
this fashion, the purchase of call options would enable the Fund or the
Portfolio to acquire the security or currency at the exercise price of the call
option plus the premium paid. At times, the net cost of acquiring the

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
security or currency in this manner may be less than the cost of acquiring the
security or currency directly. This technique also may be useful to a Fund or
the Portfolio in purchasing a large block of securities that would be more
difficult to acquire by direct market purchases. So long as it holds such a call
option, rather than the underlying security or currency itself, a Fund or the
Portfolio is partially protected from any unexpected decline in the market price
of the underlying security or currency and, in such event, could allow the call
option to expire, incurring a loss only to the extent of the premium paid for
the option.
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio also may purchase call options on underlying securities or
currencies it owns to avoid realizing losses that would result in a reduction of
a Fund's or the Portfolio's current return. For example, where a Fund or the
Portfolio has written a call option on an underlying security or currency having
a current market value below the price at which it purchased the security or
currency, an increase in the market price could result in the exercise of the
call option written by the Fund or the Portfolio and the realization of a loss
on the underlying security or currency. Accordingly, the Fund or the Portfolio
could purchase a call option on the same underlying security or currency, which
could be exercised to fulfill the Fund's or the Portfolio's delivery obligations
under its written call (if it is exercised). This strategy could allow the Fund
or the Portfolio to avoid selling the portfolio security or currency at a time
when it has an unrealized loss; however, the Fund or the Portfolio would have to
pay a premium to purchase the call option plus transaction costs.
 
   
Aggregate premiums paid for put and call options will not exceed 5% of the
Government Income Fund, the Strategic Income Fund, the Growth & Income's Fund's
or the Portfolio's total assets at the time of purchase.
    
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
or the Portfolio may attempt to accomplish objectives similar to those involved
in using Forward Contracts by purchasing put or call options on currencies. A
put option gives a Fund or the Portfolio as purchaser the right (but not the
obligation) to sell a specified amount of currency at the exercise price at any
time until (American Style) or on (European Style) the expiration of the option.
A call option gives a Fund or the Portfolio as purchaser the right (but not the
obligation) to purchase a specified amount of currency at the exercise price at
any time until (American Style) or on (European Style) the expiration of the
option. A Fund or the Portfolio might purchase a currency put option, for
example, to protect itself against a decline in the dollar value of a currency
in which it holds or anticipates holding securities. If the currency's value
should decline against the dollar, the loss in currency value should be offset,
in whole or in part, by an increase in the value of the put. If the value of the
currency instead should rise against the dollar, any gain to the Fund or the
Portfolio would be reduced by the premium it had paid for the put option. A
currency call option might be purchased, for example, in anticipation of, or to
protect against, a rise in the value against the dollar of a currency in which
the Fund or the Portfolio anticipates purchasing securities.
 
Options may be either listed on an exchange or traded in over-the-counter
("OTC") markets. Listed options are third-party contracts (I.E., performance of
the obligations of the purchaser and seller is guaranteed by the exchange or
clearing corporation), and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates. The Funds and the Portfolio will not purchase an OTC option unless the
Fund or the Portfolio believes that daily valuations for such options are
readily obtainable. OTC options differ from exchange-traded options in that OTC
options are transacted with dealers directly and not through a clearing
corporation (which guarantees performance). Consequently, there is a risk of
non-performance by the dealer. Since no exchange is involved, OTC options are
valued on the basis of the average of the last bid prices obtained from dealers,
unless a quotation from only one dealer is available, in which case only that
dealer's price will be used. In the case of OTC options, there can be no
assurance that a liquid secondary market will exist for any particular option at
any specific time.
 
   
The staff of the SEC considers purchased OTC options to be illiquid securities.
A Fund or the Portfolio may also sell OTC options and, in connection therewith,
segregate assets or cover its obligations with respect to OTC options written by
the Fund or the Portfolio. The assets used as cover for OTC options written by a
Fund or the Portfolio will be considered illiquid unless the OTC options are
sold to qualified dealers who agree that the Fund or the Portfolio may
repurchase any OTC option it writes at a maximum price to be calculated by a
formula set forth in the option agreement. The cover for an OTC option written
subject to this procedure would be considered illiquid only to the extent that
the maximum repurchase price under the formula exceeds the intrinsic value of
the option.
    
 
A Fund's or the Portfolio's ability to establish and close out positions in
exchange-listed options depends on the existence of a liquid market. Each Fund
and the Portfolio intends to purchase or write only those exchange-traded
options for which there appears to be a liquid secondary market. However, there
can be no assurance that such a market will exist at any

                        AIM GLOBAL GROWTH & INCOME FUND
particular time. Closing transactions can be made for OTC options only by
negotiating directly with the contra party or by a transaction in the secondary
market if any such market exists. Although each Fund and the Portfolio will
enter into OTC options only with contra parties that are expected to be capable
of entering into closing transactions with the Fund or the Portfolio, there is
no assurance that the Fund or the Portfolio will in fact be able to close out an
OTC option position at a favorable price prior to expiration. In the extent of
insolvency of the contra party, the Fund or the Portfolio might be unable to
close out an OTC option position at any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts except that all settlements are in cash and gain or loss depends on
changes in the index in question (and thus on price movements in the securities
market or a particular market sector generally) rather than on price movements
in individual securities or futures contracts. When a Fund or the Portfolio
writes a call on an index, it receives a premium and agrees that, prior to the
expiration date, the purchaser of the call, upon exercise of the call, will
receive from the Fund or the Portfolio an amount of cash if the closing level of
the index upon which the call is based is greater than the exercise price of the
call. The amount of cash is equal to the difference between the closing price of
the index and the exercise price of the call times a specified multiple (the
"multiplier"), which determines the total dollar value for each point of such
difference. When a Fund or the Portfolio buys a call on an index, it pays a
premium and has the same rights as to such call as are indicated above. When a
Fund or the Portfolio buys a put on an index, it pays a premium and has the
right, prior to the expiration date, to require the seller of the put, upon the
Fund's or the Portfolio's exercise of the put, to deliver to the Fund or the
Portfolio an amount of cash if the closing level of the index upon which the put
is based is less than the exercise price of the put, which amount of cash is
determined by the multiplier, as described above for calls. When a Fund or the
Portfolio writes a put on an index, it receives a premium and the purchaser has
the right, prior to the expiration date, to require the Fund or the Portfolio to
deliver to it an amount of cash equal to the difference between the closing
level of the index and the exercise price times the multiplier, if the closing
level is less than the exercise price.
 
The risks of investment in index options may be greater than options on
securities. Because index options are settled in cash, when a Fund or the
Portfolio writes a call on an index it cannot provide in advance for its
potential settlement obligations by acquiring and holding the underlying
securities. A Fund or the Portfolio can offset some of the risk of writing a
call index option position by holding a diversified portfolio of securities
similar to those on which the underlying index is based. However, a Fund or the
Portfolio cannot, as a practical matter, acquire and hold a portfolio containing
exactly the same securities as underlie the index and, as a result, bears a risk
that the value of the securities held will vary from the value of the index.
 
Even if a Fund or the Portfolio could assemble a securities portfolio that
exactly reproduced the composition of the underlying index, it still would not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing index options. When an index option is exercised, the amount of cash
that the holder is entitled to receive is determined by the difference between
the exercise price and the closing index level on the date when the option is
exercised. As with other kinds of options, the Fund or the Portfolio, as the
call writer, will not know that it has been assigned until the next business day
at the earliest. The time lag between exercise and notice of assignment poses no
risk for the writer of a covered call on a specific underlying security, such as
common stock, because there the writer's obligation is to deliver the underlying
security, not to pay its value as of a fixed time in the past. So long as the
writer already owns the underlying security, it can satisfy its settlement
obligations by simply delivering it, and the risk that its value may have
declined since the exercise date is borne by the exercising holder. In contrast,
even if the writer of an index call holds securities that exactly match the
composition of the underlying index, it will not be able to satisfy its
assignment obligations by delivering those securities against payment of the
exercise price. Instead, it will be required to pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that it
has been assigned, the index may have declined, with a corresponding decline in
the value of its securities portfolio. This "timing risk" is an inherent
limitation on the ability of index call writers to cover their risk exposure by
holding securities positions.
 
If a Fund or the Portfolio purchases an index option and exercises it before the
closing index value for that day is available, it runs the risk that the level
of the underlying index may subsequently change. If such a change causes the
exercised option to fall out-of-the-money, the Fund or the Portfolio will be
required to pay the difference between the closing index value and the exercise
price of the option (times the applicable multiplier) to the assigned writer.

INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
or the Portfolio may enter into interest rate or currency futures contracts,
including futures contracts on indices of debt securities, ("Futures" or
"Futures Contracts"), as a hedge against changes in prevailing levels of
interest rates or currency exchange rates in order to establish more definitely
the effective return on securities or currencies held or intended to be acquired
by the Fund or the Portfolio. The Government Income Fund's, the Strategic Income
Fund's, the Growth & Income Fund's or the Portfolio's hedging may include sales
of Futures as an offset against the effect of expected increases in interest
rates or decreases in currency exchange rates, and purchases of Futures as an
offset against the effect of expected declines in interest rates or increases in
currency exchange rates. The Growth & Income Fund may also enter into stock
index Futures Contracts as a hedge against changes in stock prices.
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio only will enter into Futures Contracts that are traded on
futures exchanges and are standardized as to maturity date and underlying
financial instrument. Futures exchanges and trading thereon in the United States
are regulated under the Commodity Exchange Act by the Commodity Futures Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used to reduce a Fund's or the Portfolio's exposure to interest rate and
currency exchange rate fluctuations, a Fund or the Portfolio may be able to
hedge exposure more effectively and at a lower cost through using Futures
Contracts.
 
A Futures Contract provides for the future sale by one party and purchase by
another party of a specified amount of a specific financial instrument (debt
security or currency) for a specified price at a designated date, time and
place. An index Futures Contract provides for the delivery, at a designated
date, time and place, of an amount of cash equal to a specified dollar amount
times the difference between the index value at the close of trading on the
contract and the price at which the Futures Contract is originally struck; no
physical delivery of the securities comprising the index is made. Brokerage fees
are incurred when a Futures Contract is bought or sold, and margin deposits must
be maintained at all times the Futures Contract is outstanding.
 
Although Futures Contracts typically require future delivery of and payment for
financial instruments or currencies, Futures Contracts usually are closed out
before the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering into an offsetting Futures Contract purchase or sale,
respectively, for the same aggregate amount of the identical financial
instrument or currency and the same delivery date. If the offsetting purchase
price is less than the original sale price, the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund or the Portfolio realizes a
gain; if it is more, the Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund or the Portfolio realizes a loss. Conversely, if the
offsetting sale price is more than the original purchase price, the Government
Income Fund, the Strategic Income Fund, the Growth & Income Fund or the
Portfolio realizes a gain; if it is less, the Government Income Fund, the
Strategic Income Fund, the Growth & Income Fund or the Portfolio realizes a
loss. The transaction costs also must be included in these calculations. There
can be no assurance, however, that a Fund or the Portfolio will be able to enter
into an offsetting transaction with respect to a particular Futures Contract at
a particular time. If a Fund or the Portfolio is not able to enter into an
offsetting transaction, the Fund or the Portfolio will continue to be required
to maintain the margin deposits on the Futures Contract.
 
As an example of an offsetting transaction, the contractual obligations arising
from the sale of one Futures Contract of September Deutschemarks on an exchange
may be fulfilled at any time before delivery under the Futures Contract is
required (I.E., on a specified date in September, the "delivery month") by the
purchase of another Futures Contract of September Deutschemarks on the same
exchange. In such instance, the difference between the price at which the
Futures Contract was sold and the price paid for the offsetting purchase, after
allowance for transaction costs, represents the profit or loss to the Government
Income Fund, the Strategic Income Fund, the Growth & Income Fund or the
Portfolio.
 
The Government Income Fund's, the Strategic Income Fund's, the Growth & Income
Fund's and the Portfolio's Futures transactions will be entered into for hedging
purposes only; that is, Futures Contracts will be sold to protect against a
decline in the price of securities or currencies that the Fund or the Portfolio
owns, or Futures Contracts will be purchased to protect the Fund or the
Portfolio against an increase in the price of securities or currencies it has
committed to purchase or expects to purchase.

"Margin" with respect to Futures Contracts is the amount of funds that must be
deposited by the Government Income Fund, the Strategic Income Fund, the Growth &
Income Fund or the Portfolio in order to initiate Futures trading and to
maintain the Fund's or the Portfolio's open positions in Futures Contracts. A
margin deposit made when the Futures Contract is entered into ("initial margin")
is intended to assure a Fund's or the Portfolio's performance under the Futures
Contract. The margin required for a particular Futures Contract is set by the
exchange on which the Futures Contract is traded, and may be modified
significantly from time to time by the exchange during the term of the Futures
Contract.
 
Subsequent payments, called "variation margin," to and from the futures
commission merchant through which the Fund or the Portfolio entered into the
Futures Contract will be made on a daily basis as the price of the underlying
security, currency or index fluctuates making the Futures Contract more or less
valuable, a process known as marking-to-market.
 
    RISKS OF USING FUTURES CONTRACTS. The prices of Futures Contracts are
volatile and are influenced, among other things, by actual and anticipated
changes in interest and currency rates, which in turn are affected by fiscal and
monetary policies and national and international political and economic events.
 
There is a risk of imperfect correlation between changes in prices of Futures
Contracts and prices of the securities or currencies in a Fund's or the
Portfolio's portfolio being hedged. The degree of imperfection of correlation
depends upon circumstances such as: variations in speculative market demand for
Futures and for securities or currencies, including technical influences in
Futures trading; and differences between the financial instruments being hedged
and the instruments underlying the standard Futures Contracts available for
trading. A decision of whether, when, and how to hedge involves skill and
judgment, and even a well-conceived hedge may be unsuccessful to some degree
because of unexpected market behavior or interest or currency rate trends.
 
Because of the low margin deposits required, Futures trading involves an
extremely high degree of leverage. As a result, a relatively small price
movement in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example, if at the time of purchase, 10% of
the value of the Futures Contract is deposited as margin, a subsequent 10%
decrease in the value of the Futures Contract would result in a total loss of
the margin deposit, before any deduction for the transaction costs, if the
account were then closed out. A 15% decrease would result in a loss equal to
150% of the original margin deposit, if the Futures Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and option on Futures Contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a Futures Contract
or option may vary either up or down from the previous day's settlement price at
the end of a trading session. Once the daily limit has been reached in a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a particular trading day and therefore does not limit potential losses, because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and option prices occasionally have moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If a Fund or the Portfolio were unable to liquidate a Futures or option on
Futures position due to the absence of a liquid secondary market or the
imposition of price limits, it could incur substantial losses. The Fund or the
Portfolio would continue to be subject to market risk with respect to the
position. In addition, except in the case of purchased options, the Fund or the
Portfolio would continue to be required to make daily variation margin payments
and might be required to maintain the position being hedged by the Future or
option or to maintain cash or securities in a segregated account.
 
Certain characteristics of the Futures market might increase the risk that
movements in the prices of Futures Contracts or options on Futures might not
correlate perfectly with movements in the prices of the investments being
hedged. For example, all participants in the Futures and options on Futures
markets are subject to daily variation margin calls and might be compelled to
liquidate Futures or options on Futures positions whose prices are moving
unfavorably to avoid being subject to further calls. These liquidations could
increase price volatility of the instruments and distort the normal price
relationship between the Futures or options and the investments being hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous than margin requirements in the securities markets, there might be
increased participation by speculators in the Futures markets. This
participation also might cause temporary price distortions. In addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading" and other investment strategies might result in
temporary price distortions.

OPTIONS ON FUTURES CONTRACTS
Options on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the premium paid, to assume a position in a Futures Contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the period of the option. Upon
exercise of the option, the delivery of the Futures position by the writer of
the option to the holder of the option will be accompanied by delivery of the
accumulated balance in the writer's Futures margin account, which represents the
amount by which the market price of the Futures Contract, at exercise, exceeds
(in the case of a call) or is less than (in the case of a put) the exercise
price of the option on the Futures Contract. If an option is exercised on the
last trading day prior to the expiration date of the option, the settlement will
be made entirely in cash equal to the difference between the exercise price of
the option and the closing level of the securities, currencies or index upon
which the Futures Contract is based on the expiration date. Purchasers of
options who fail to exercise their options prior to the exercise date suffer a
loss of the premium paid.
 
The purchase of call options on Futures can serve as a long hedge, and the
purchase of put options on Futures can serve as a short hedge. Writing call
options on Futures can serve as a limited short hedge, and writing put options
on Futures can serve as a limited long hedge, using a strategy similar to that
used for writing options on securities, foreign currencies or indices.
 
If a Fund or the Portfolio writes an option on a Futures Contract, it will be
required to deposit initial and variation margin pursuant to requirements
similar to those applicable to Futures Contracts. Premiums received from the
writing of an option on a Futures Contract are included in the initial margin
deposit.
 
A Fund or the Portfolio may seek to close out an option position by selling an
option covering the same Futures Contract and having the same exercise price and
expiration date. The ability to establish and close out positions on such
options is subject to the maintenance of a liquid secondary market.
 
LIMITATIONS ON USE OF FUTURES, OPTIONS ON FUTURES AND CERTAIN OPTIONS ON
CURRENCIES
   
To the extent that a Fund or the Portfolio enters into Futures Contracts,
options on Futures Contracts and options on foreign currencies traded on a
CFTC-regulated exchange, in each case other than for BONA FIDE hedging purposes
(as defined by the CFTC), the aggregate initial margin and premiums required to
establish those positions (excluding the amount by which options are
"in-the-money") will not exceed 5% of the liquidation value of a Fund's or the
Portfolio's portfolio, after taking into account unrealized profits and
unrealized losses on any contracts the Fund or the Portfolio has entered into.
In general, a call option on a Futures Contract is "in-the-money" if the value
of the underlying Futures Contract exceeds the strike, I.E., exercise, price of
the call; a put option on a Futures Contract is "in-the-money" if the value of
the underlying Futures Contract is exceeded by the strike price of the put. This
guideline may be modified by the Trust's or the Portfolio's Board of Trustees,
as applicable, without a shareholder vote. This limitation does not limit the
percentage of a Fund's or the Portfolio's assets at risk to 5%.
    
 
FORWARD CONTRACTS
A Forward Contract is an obligation, generally arranged with a commercial bank
or other currency dealer, to purchase or sell a currency against another
currency at a future date and price as agreed upon by the parties. The
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio either may accept or make delivery of the currency at the maturity
of the Forward Contract. A Fund or the Portfolio may also, if its contra party
agrees, prior to maturity, enter into a closing transaction involving the
purchase or sale of an offsetting contract.
 
A Fund or the Portfolio engages in forward currency transactions in anticipation
of, or to protect itself against, fluctuations in exchange rates. A Fund or the
Portfolio might sell a particular foreign currency forward, for example, when it
holds bonds denominated in a foreign currency but anticipates, and seeks to be
protected against, a decline in the currency against the U.S. dollar. Similarly,
a Fund or the Portfolio might sell the U.S. dollar forward when it holds bonds
denominated in U.S. dollars but anticipates, and seeks to be protected against,
a decline in the U.S. dollar relative to other currencies. Further, the Funds or
the Portfolio might purchase a currency forward to "lock in" the price of
securities denominated in that currency that it anticipates purchasing.
 
Forward Contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any stage for trades. The Government Income Fund, the Strategic Income Fund, the
Growth & Income Fund or

the Portfolio will enter into such Forward Contracts with major U.S. or foreign
banks and securities or currency dealers in accordance with guidelines approved
by the Trust's or the Portfolio's Board of Trustees, as applicable.
    
 
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
or the Portfolio may enter into Forward Contracts either with respect to
specific transactions or with respect to the overall investment of the Fund or
the Portfolio. The precise matching of the Forward Contract amounts and the
value of specific securities generally will not be possible because the future
value of such securities in foreign currencies will change as a consequence of
market movements in the value of those securities between the date the Forward
Contract is entered into and the date it matures. Accordingly, it may be
necessary for the Fund or the Portfolio to purchase additional foreign currency
on the spot (I.E., cash) market (and bear the expense of such purchase) if the
market value of the security is less than the amount of foreign currency the
Fund or the Portfolio is obligated to deliver and if a decision is made to sell
the security and make delivery of the foreign currency. Conversely, it may be
necessary to sell on the spot market some of the foreign currency the Fund or
the Portfolio is obligated to deliver. The projection of short-term currency
market movements is extremely difficult, and the successful execution of a
short-term hedging strategy is highly uncertain. Forward Contracts involve the
risk that anticipated currency movements will not be predicted accurately,
causing the Fund or the Portfolio to sustain losses on these contracts and
transaction costs.
 
At or before the maturity of a Forward Contract requiring the Fund or the
Portfolio to sell a currency, the Fund or the Portfolio either may sell a
portfolio security and use the sale proceeds to make delivery of the currency or
retain the security and offset its contractual obligation to deliver the
currency by purchasing a second contract pursuant to which the Fund or the
Portfolio will obtain, on the same maturity date, the same amount of the
currency that it is obligated to deliver. Similarly, the Fund or the Portfolio
may close out a Forward Contract requiring it to purchase a specified currency
by entering into a second contract, if its contra party agrees, entitling it to
sell the same amount of the same currency on the maturity date of the first
contract. The Fund or the Portfolio would realize a gain or loss as a result of
entering into such an offsetting Forward Contract under either circumstance to
the extent the exchange rate or rates between the currencies involved moved
between the execution dates of the first contract and the offsetting contract.
 
The cost to a Fund or the Portfolio of engaging in Forward Contracts varies with
factors such as the currencies involved, the length of the contract period and
the market conditions then prevailing. Because Forward Contracts usually are
entered into on a principal basis, no fees or commissions are involved. The use
of Forward Contracts does not eliminate fluctuations in the prices of the
underlying securities the Fund or the Portfolio owns or intends to acquire, but
it does establish a rate of exchange in advance. In addition, while Forward
Contracts limit the risk of loss due to a decline in the value of the hedged
currencies, they also limit any potential gain that might result should the
value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
A Fund or the Portfolio may use options on foreign currencies, Futures on
foreign currencies, options on Futures on foreign currencies and Forward
Contracts to hedge against movements in the values of the foreign currencies in
which the Fund's or the Portfolio's securities are denominated. Such currency
hedges can protect against price movements in a security that a Fund or the
Portfolio owns or intends to acquire that are attributable to changes in the
value of the currency in which it is denominated. Such hedges do not, however,
protect against price movements in the securities that are attributable to other
causes.
 
A Fund or the Portfolio might seek to hedge against changes in the value of a
particular currency when no Futures Contract, Forward Contract or option
involving that currency is available or one of such contracts is more expensive
than certain other contracts. In such cases, the Fund or the Portfolio may hedge
against price movements in that currency by entering into a contract on another
currency or basket of currencies, the values of which the Sub-adviser believes
will have a positive correlation to the value of the currency being hedged. The
risk that movements in the price of the contract will not correlate perfectly
with movements in the price of the currency being hedged is magnified when this
strategy is used.
 
The value of Futures Contracts, options on Futures Contracts, Forward Contracts
and options on foreign currencies depends on the value of the underlying
currency relative to the U.S. dollar. Because foreign currency transactions
occurring in the interbank market might involve substantially larger amounts
than those involved in the use of Futures Contracts, Forward Contracts or
options, a Fund or the Portfolio could be disadvantaged by dealing in the odd
lot market (generally consisting of transactions of less than $1 million) for
the underlying foreign currencies at prices that are less favorable than for
round lots.

                        AIM GLOBAL GROWTH & INCOME FUND
 
There is no systematic reporting of last sale information for foreign currencies
or any regulatory requirements that quotations available through dealers or
other market sources be firm or revised on a timely basis. Quotation information
generally is representative of very large transactions in the interbank market
and thus might not reflect odd-lot transactions where rates might be less
favorable. The interbank market in foreign currencies is a global,
round-the-clock market. To the extent the U.S. options or Futures markets are
closed while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that cannot
be reflected in the markets for the Futures contracts or options until they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies might be required to take place within the country issuing the
underlying currency. Thus, a Fund or the Portfolio might be required to accept
or make delivery of the underlying foreign currency in accordance with any U.S.
or foreign regulations regarding the maintenance of foreign banking arrangements
by U.S. residents and might be required to pay any fees, taxes and charges
associated with such delivery assessed in the issuing country.
 
COVER
Transactions using Forward Contracts, Futures Contracts and options (other than
options purchased by a Fund or the Portfolio) expose the Fund or the Portfolio
to an obligation to another party. A Fund or the Portfolio will not enter into
any such transactions unless it owns either (1) an offsetting ("covered")
position in securities, currencies, or other options, Forward Contracts or
Futures Contracts, or (2) cash, receivables and short-term debt securities with
a value sufficient at all times to cover its potential obligations not covered
as provided in (1) above. Each Fund and the Portfolio will comply with SEC
guidelines regarding cover for these instruments and, if the guidelines so
require, set aside cash or liquid securities.
 
Assets used as cover or held in a segregated account cannot be sold while the
position in the corresponding Forward Contract, Futures Contract or option is
open, unless they are replaced with other appropriate assets. If a large portion
of a Fund's or the Portfolio's assets are used for cover or segregated accounts,
it could affect portfolio management or the Fund's or the Portfolio's ability to
meet redemption requests or other current obligations.
 
INTEREST RATE AND CURRENCY SWAPS
The Strategic Income Fund and the Portfolio usually will enter into interest
rate swaps on a net basis, that is, the two payment streams are netted out in a
cash settlement on the payment date or dates specified in the instrument, with
the Strategic Income Fund or the Portfolio receiving or paying, as the case may
be, only the net amount of the two payments. The net amount of the excess, if
any, of each of the Strategic Income Fund's and the Portfolio's obligations over
its entitlements with respect to each swap will be accrued on a daily basis and
an amount of cash or liquid securities having an aggregate net asset value at
least equal to the accrued excess will be maintained in an account by a
custodian that satisfies the requirements of the 1940 Act. The Strategic Income
Fund and the Portfolio will also establish and maintain such segregated accounts
with respect to its total obligations under any swaps that are not entered into
on a net basis and with respect to any caps or floors that are written by that
Fund or the Portfolio. The Sub-adviser, the Strategic Income Fund and the
Portfolio believe that swaps, caps and floors do not constitute senior
securities under the 1940 Act and, accordingly, will not treat them as being
subject to the Fund's and the Portfolio's borrowing restrictions. The Strategic
Income Fund and the Portfolio will not enter into any swap, cap, floor, collar
or other derivative transaction unless, at the time of entering into the
transaction, the unsecured long-term debt rating of the counterparty combined
with any credit enhancements is rated at least A by Moody's or S&P, or has an
equivalent rating from a nationally recognized statistical rating organization
or is determined to be of equivalent credit quality by the Sub-adviser. If a
counterparty defaults, the Strategic Income Fund or the Portfolio may have
contractual remedies pursuant to the agreements related to the transactions. The
swap market has grown substantially in recent years, with a large number of
banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. As a result, the swap market has
become relatively liquid. Caps, floors and collars are more recent innovations
for which standardized documentation has not yet been fully developed and, for
that reason, they are less liquid than swaps.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
The Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio each may invest up to 15% of net assets in illiquid
securities. Securities may be considered illiquid if a Fund or the Portfolio
cannot reasonably expect within seven days to receive approximately the amount
at which the Fund or the Portfolio values such securities. The sale of illiquid
securities, if they can be sold at all, generally will require more time and
result in higher brokerage charges or dealer discounts and other selling
expenses than will the sale of liquid securities, such as securities eligible
for trading on U.S. securities exchanges or in the over-the-counter markets.
Moreover, restricted securities, which may be illiquid for purposes of this
limitation often sell, if at all, at a price lower than similar securities that
are not subject to restrictions on resale.
 
Illiquid securities include those that are subject to restrictions contained in
the securities laws of other countries. However, securities that are freely
marketable in the country where they are principally traded, but would not be
freely marketable in the United States, will not be considered illiquid. Where
registration is required, each Fund and the Portfolio may be obligated to pay
all or part of the registration expenses and a considerable period may elapse
between the time of the decision to sell and the time a Fund or the Portfolio
may be permitted to sell a security under an effective registration statement.
If, during such a period, adverse market conditions were to develop, a Fund or
the Portfolio might obtain a less favorable price than prevailed when it decided
to sell.
 
Not all restricted securities are illiquid. In recent years a large
institutional market has developed for certain securities that are not
registered under the Securities Act of 1933, as amended ("1933 Act"), including
private placements, repurchase agreements, commercial paper, foreign securities
and corporate bonds and notes. These instruments are often restricted securities
because the securities are sold in transactions not requiring registration.
Institutional investors generally will not seek to sell these instruments to the
general public, but instead will often depend either on an efficient
institutional market in which such unregistered securities can be readily resold
or on an issuer's ability to honor a demand for repayment. Therefore, the fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule 144A under the 1933 Act establishes a "safe harbor" from the registration
requirements of the 1933 Act for resales of certain securities to qualified
institutional buyers. Institutional markets for restricted securities have
developed as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance and settlement of unregistered securities of domestic and foreign
issuers, such as the PORTAL System sponsored by the National Association of
Securities Dealers, Inc. An insufficient number of qualified institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a Fund or the Portfolio, however, could affect adversely the marketability of
such portfolio securities and a Fund or the Portfolio might be unable to dispose
of such securities promptly or at favorable prices.
 
   
With respect to liquidity determinations generally, the Trust's or the
Portfolio's Board of Trustees has the ultimate responsibility for determining
whether specific securities, including restricted securities eligible for resale
to qualified institutional buyers pursuant to Rule 144A under the 1933 Act, are
liquid or illiquid. The Board has delegated the function of making day-to-day
determinations of liquidity to the Sub-adviser in accordance with procedures
approved by the Board. The Sub-adviser takes into account a number of factors in
reaching liquidity decisions, including: (i) the frequency of trading in the
security; (ii) the number of dealers that make quotes for the security; (iii)
the number of dealers that have undertaken to make a market in the security;
(iv) the number of other potential purchasers; and (v) the nature of the
security and how trading is effected (e.g., the time needed to sell the
security, how offers are solicited and the mechanics of transfer). The
Sub-adviser will monitor the liquidity of securities held by each Fund and the
Portfolio and report periodically on such decisions to the Trust's or the
Portfolio's Board of Trustees. Moreover, as noted in the

                        AIM GLOBAL GROWTH & INCOME FUND
Prospectus, certain securities, such as those subject to registration
restrictions of more than seven days, will generally be treated as illiquid. If
the liquidity percentage restriction of a Fund or the Portfolio is satisfied at
the time of investment, a later increase in the percentage of illiquid
securities held by a Fund or the Portfolio resulting from a change in market
value or assets will not constitute a violation of that restriction. If as a
result of a change in market value or assets, the percentage of illiquid
securities held by the Fund or Portfolio increases above the applicable limit,
the Sub-adviser will take appropriate steps to bring the aggregate amount of
illiquid assets back within the prescribed limitations as soon as reasonably
practicable, taking into account the effect of any disposition on the Fund or
the Portfolio.
 
FOREIGN SECURITIES
    POLITICAL, SOCIAL AND ECONOMIC RISKS. Investing in securities of non-U.S.
companies may entail additional risks due to the potential political, social and
economic instability of certain countries and the risks of expropriation,
nationalization, confiscation or the imposition of restrictions on foreign
investment, convertibility of currencies into U.S. dollars and on repatriation
of capital invested. In the event of such expropriation, nationalization or
other confiscation by any country, either a Fund or the Portfolio could lose its
entire investment in any such country.
 
    RELIGIOUS, POLITICAL AND ETHNIC INSTABILITY. Certain countries in which a
Fund or the Portfolio may invest may have groups that advocate radical religious
or revolutionary philosophies or support ethnic independence. Any disturbance on
the part of such individuals could carry the potential for widespread
destruction or confiscation of property owned by individuals and entities
foreign to such country and could cause the loss of a Fund's or the Portfolio's
investment in those countries. Instability may also result from, among other
things: (i) authoritarian governments or military involvement in political and
economic decision-making, including changes in government through
extra-constitutional means; (ii) popular unrest associated with demands for
improved political, economic and social conditions; and (iii) hostile relations
with neighboring or other countries. Such political, social and economic
instability could disrupt the principal financial markets in which a Fund or the
Portfolio invests and adversely affect the value of the Fund's or the
Portfolio's assets.
 
    FOREIGN INVESTMENT RESTRICTIONS. Certain countries prohibit or impose
substantial restrictions on investments in their capital markets, particularly
their equity markets, by foreign entities such as the Government Income Fund,
the Strategic Income Fund, the Growth & Income Fund or the Portfolio. These
restrictions or controls may at times limit or preclude investment in certain
securities and may increase the cost and expenses of a Fund or the Portfolio.
For example, certain countries require prior governmental approval before
investments by foreign persons may be made, or may limit the amount of
investment by foreign persons in a particular company, or limit the investment
by foreign persons to only a specific class of securities of a company that may
have less advantageous terms than securities of the company available for
purchase by nationals. Moreover, the national policies of certain countries may
restrict investment opportunities in issuers or industries deemed sensitive to
national interests. In addition, some countries require governmental approval
for the repatriation of investment income, capital or the proceeds of securities
sales by foreign investors. In addition, if there is a deterioration in a
country's balance of payments or for other reasons, a country may impose
restrictions on foreign capital remittances abroad. The Government Income Fund,
the Strategic Income Fund, the Growth & Income Fund or the Portfolio could be
adversely affected by delays in, or a refusal to grant, any required
governmental approval for repatriation, as well as by the application to it of
other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION. Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing on the financial statements of such a company may not reflect its
financial position or results of operations in the way they would be reflected
had such financial statements been prepared in accordance with U.S. generally
accepted accounting principles. Most of the foreign securities held by the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund or
the Portfolio will not be registered with the SEC or regulators of any foreign
country, nor will the issuers thereof be subject to the SEC's reporting
requirements. Thus, there will be less available information concerning most
foreign issuers of securities held by the Government Income Fund, the Strategic
Income Fund, the Growth & Income Fund and the Portfolio than is available
concerning U.S. issuers. In instances where the financial statements of an
issuer are not deemed to reflect accurately the financial situation of the
issuer, the Sub-adviser will take appropriate steps to evaluate the proposed
investment, which may include on-site inspection of the issuer, interviews with
its management and consultations with accountants, bankers and other
specialists. There is substantially less publicly available information about
foreign companies than there are reports and ratings published about U.S.
companies and the U.S. Government. In addition, where public information is

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
available, it may be less reliable than such information regarding U.S. issuers.
Issuers of securities in foreign jurisdictions are generally not subject to the
same degree of regulation as are U.S. issuers with respect to such matters as
restrictions on market manipulation, insider trading rules, shareholder proxy
requirements and timely disclosure of information.
 
    CURRENCY FLUCTUATIONS. Because the Funds and the Portfolio, under normal
circumstances, will invest substantial portions of their total assets in the
securities of foreign issuers which are denominated in foreign currencies, the
strength or weakness of the U.S. dollar against such foreign currencies will
account for part of each Fund's and the Portfolio's investment performance. A
decline in the value of any particular currency against the U.S. dollar will
cause a decline in the U.S. dollar value of each Fund's and the Portfolio's
holdings of securities and cash denominated in such currency and, therefore,
will cause an overall decline in their respective net asset values and any net
investment income and capital gains derived from such securities to be
distributed in U.S. dollars to shareholders of the Funds. Moreover, if the value
of the foreign currencies in which a Fund or the Portfolio receives its income
declines relative to the U.S. dollar between the receipt of the income and the
making of Fund distributions, the Fund or the Portfolio may be required to
liquidate securities in order to make distributions if the Fund or the Portfolio
has insufficient cash in U.S. dollars to meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is determined
by several factors including the supply and demand for particular currencies,
central bank efforts to support particular currencies, the relative movement of
interest rates and the pace of business activity in the other countries, and the
United States, and other economic and financial conditions affecting the world
economy.
 
Although the Funds and the Portfolio value their assets daily in terms of U.S.
dollars, they do not intend to convert holdings of foreign currencies into U.S.
dollars on a daily basis. The Funds and the Portfolio will do so from time to
time, and investors should be aware of the costs of currency conversion.
Although foreign exchange dealers do not charge a fee for conversion, they do
realize a profit based on the difference ("spread") between the prices at which
they are buying and selling various currencies. Thus, a dealer may offer to sell
a foreign currency to a Fund at one rate, while offering a lesser rate of
exchange should the Fund desire to sell that currency to the dealer.
 
    ADVERSE MARKET CHARACTERISTICS. Securities of many foreign issuers may be
less liquid and their prices more volatile than securities of comparable U.S.
issuers. In addition, foreign securities markets and brokers generally are
subject to less governmental supervision and regulation than in the U.S., and
foreign securities transactions usually are subject to fixed commissions, which
generally are higher than negotiated commissions on U.S. transactions. In
addition, foreign securities transactions may be subject to difficulties
associated with the settlement of such transactions. Delays in settlement could
result in temporary periods when assets of a Fund or the Portfolio are
uninvested and no return is earned thereon. The inability of a Fund or the
Portfolio to make intended security purchases due to settlement problems could
cause it to miss attractive opportunities. Inability to dispose of a portfolio
security due to settlement problems either could result in losses to a Fund or
the Portfolio due to subsequent declines in value of the portfolio security or,
if the Fund or the Portfolio has entered into a contract to sell the security,
could result in possible liability to the purchaser. The Sub-adviser will
consider such difficulties when determining the allocation of each Fund's or the
Portfolio's assets, although the Sub-adviser does not believe that such
difficulties will have a material adverse effect on the Funds' or the
Portfolio's portfolio trading activities.
 
The Funds and the Portfolio may use foreign custodians, which may involve risks
in addition to those related to the use of U.S. custodians. Such risks include
uncertainties relating to: (i) determining and monitoring the financial
strength, reputation and standing of the foreign custodian; (ii) maintaining
appropriate safeguards to protect the Funds' and the Portfolio's investments and
(iii) possible difficulties in obtaining and enforcing judgments against such
custodians.
 
    WITHHOLDING TAXES. Each Fund's and the Portfolio's net investment income
from foreign issuers may be subject to withholding taxes by the foreign issuer's
country, thereby reducing the Fund's and the Portfolio's income or delaying the
receipt of income where those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION. To the extent a Fund invests a significant portion of its
assets in securities of issuers located in a particular country or region of the
world, such Portfolio may be subject to greater risks and may experience greater
volatility than a fund that is more broadly diversified geographically.

    SPECIAL CONSIDERATIONS AFFECTING WESTERN EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market") (Belgium,
Denmark, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands,
Portugal, Spain, and the United Kingdom) eliminated certain import tariffs and
quotas and other trade barriers with respect to one another over the past
several years. The Sub-adviser believes that this deregulation should improve
the prospects for economic growth in many Western European countries. Among
other things, the deregulation could enable companies domiciled in one country
to avail themselves of lower labor costs existing in other countries. In
addition, this deregulation could benefit companies domiciled in one country by
opening additional markets for their goods and services in other countries.
Since, however, it is not clear what the exact form or effect of these Common
Market reforms will be on business in Western Europe, it is impossible to
predict the long-term impact of the implementation of these programs on the
securities owned by a Fund.
 
    SPECIAL CONSIDERATIONS AFFECTING RUSSIA AND EASTERN EUROPEAN COUNTRIES.
Investing in Russia and Eastern European countries involves a high degree of
risk and special considerations not typically associated with investing in the
United States securities markets, and should be considered highly speculative.
Such risks include: (1) delays in settling portfolio transactions and risk of
loss arising out of the system of share registration and custody; (2) the risk
that it may be impossible or more difficult than in other countries to obtain
and/or enforce a judgement; (3) pervasiveness of corruption and crime in the
economic system; (4) currency exchange rate volatility and the lack of available
currency hedging instruments; (5) higher rates of inflation (including the risk
of social unrest associated with periods of hyper-inflation) and high
unemployment; (6) controls on foreign investment and local practices disfavoring
foreign investors and limitations on repatriation of invested capital, profits
and dividends, and on a fund's ability to exchange local currencies for U.S.
dollars; (7) political instability and social unrest and violence; (8) the risk
that the governments of Russia and Eastern European countries may decide not to
continue to support the economic reform programs implemented recently and could
follow radically different political and/or economic policies to the detriment
of investors, including non-market-oriented policies such as the support of
certain industries at the expense of other sectors or investors, or a return to
the centrally planned economy that existed when such countries had a communist
form of government; (9) the financial condition of companies in these countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of international trade; (11) the risk that the tax system in these countries
will not be reformed to prevent inconsistent, retroactive and/or exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly since 1990. The general government position has deteriorated as a
result of weakening economic growth and stimulative measures taken to support
economic activity and to restore financial stability. Although the decline in
interest rates and fiscal stimulation packages have helped to contain
recessionary forces, uncertainties remain. Japan is also heavily dependent upon
international trade, so its economy is especially sensitive to trade barriers
and disputes. Japan has had difficult relations with its trading partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible that trade sanctions and other protectionist measures could impact
Japan adversely in both the short and the long term.
 
The common stocks of many Japanese companies trade at high price-earnings
ratios. Differences in accounting methods make it difficult to compare the
earnings of Japanese companies with those of companies in other countries,
especially in the U.S. In general, however, reported net income in Japan is
understated relative to U.S. accounting standards and this is one reason why
price-earnings ratios of the stocks of Japanese companies have tended
historically to be higher than those for U.S. stocks. In addition, Japanese
companies have tended to have higher growth rates than U.S. companies and
Japanese interest rates have generally been lower than in the U.S., both of
which factors tend to result in lower discount rates and higher price-earnings
ratios in Japan than in the U.S.
 
The Japanese securities markets are less regulated than those in the United
States. Evidence has emerged from time to time of distortion of market prices to
serve political or other purposes. Shareholders' rights are not always equally
enforced. In addition, Japan's banking industry is undergoing problems related
to bad loans and declining values in real estate.
 
    SPECIAL CONSIDERATIONS AFFECTING PACIFIC REGION COUNTRIES. Certain of the
risks associated with international investments are heightened for investments
in Pacific region countries. For example, some of the currencies of Pacific
region countries have experienced steady devaluations relative to the U.S.
dollar, and major adjustments have been made periodically in certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes also

exist between South Korea and North Korea. In addition, the Funds may invest in
Hong Kong, which reverted to Chinese Administration on July 1, 1997. Investments
in Hong Kong may be subject to expropriation, national, nationalization or
confiscation, in which case a Fund could lose its entire investment in Hong
Kong. In addition, the reversion of Hong Kong also presents a risk that the Hong
Kong dollar will be devalued and a risk of possible loss of investor confidence
in Hong Kong's currency, stock market and assets.
 
    SPECIAL CONSIDERATIONS AFFECTING LATIN AMERICAN COUNTRIES. Most Latin
American countries have experienced substantial, and in some periods extremely
high, rates of inflation for many years. Inflation and rapid fluctuations in
inflation rates have had and may continue to have very negative effects on the
economies and securities markets of certain Latin American countries. Certain
Latin American countries are also among the largest debtors to commercial banks
and foreign governments. At times certain Latin American countries have declared
moratoria on the payment of principal and/or interest on external debt. In
addition, certain Latin American securities markets have experienced high
volatility in recent years.
 
Latin American countries may also close certain sectors of their economies to
equity investments by foreigners. Further due to the absence of securities
markets and publicly owned corporations and due to restrictions on direct
investment by foreign entities, investments may only be made in certain Latin
American countries solely or primarily through governmentally approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by the
market. This type of system can lead to sudden and large adjustments in the
currency which, in turn, can have a disruptive and negative effect on foreign
investors. For example, in late 1994, the value of the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
   
    SPECIAL CONSIDERATIONS AFFECTING EMERGING MARKETS. The Strategic Income
Fund, the Growth & Income Fund and the Portfolio may invest in debt securities
in emerging markets. Investing in securities in emerging countries may entail
greater risks than investing in debt securities in developed countries.
Similarly, for Growth & Income Fund, investing in the equity securities of
companies in emerging markets entails additional risks. These risks affecting
debt and equity investments in emerging markets include (i) less social,
political and economic stability; (ii) the small current size of the markets for
such securities and the currently low or nonexistent volume of trading, which
result in a lack of liquidity and in greater price volatility; (iii) certain
national policies which may restrict the Funds' and the Portfolio's investment
opportunities, including restrictions on investment in issuers or industries
deemed sensitive to national interests; (iv) foreign taxation; and (v) the
absence of developed structures governing private or foreign investment or
allowing for judicial redress for injury to private property.
    
 
Settlement mechanisms in emerging securities markets may be less efficient and
reliable than in more developed markets. In such emerging securities markets
there may be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and may continue to have negative effects on the economies and securities
markets of certain emerging market countries.

- --------------------------------------------------------------------------------
 
   
Each Fund and the Portfolio has adopted the following investment limitations as
fundamental policies which may not be changed without approval by the holders of
a majority of the outstanding shares of the Fund or Portfolio, as applicable.
Whenever the High Income Fund is requested to vote on a change in the investment
limitations of the Portfolio, the Fund will hold a meeting of its shareholders
and will cast its votes as instructed by its shareholders.
    
 
                             GOVERNMENT INCOME FUND
 
The Government Income Fund may not:
 
        (1) Purchase any security if, as a result of that purchase, 25% or more
    of the Fund's total assets would be invested in securities of issuers having
    their principal business activities in the same industry, except that this
    limitation does not apply to securities issued or guaranteed by the U.S.
    government, its agencies or instrumentalities;
 
        (2) Purchase or sell real estate, except that investments in securities
    of issuers that invest in real estate and investments in mortgage-based
    securities, mortgage participations or other instruments supported by
    interests in real estate are not subject to this limitation, and except that
    the Fund may exercise rights under agreements relating to such securities,
    including the right to enforce security interests and to hold real estate
    acquired by reason of such enforcement until that real estate can be
    liquidated in an orderly manner;
 
        (3) Engage in the business of underwriting securities of other issuers,
    except to the extent that the Fund might be considered an underwriter under
    the federal securities laws in connection with its disposition of portfolio
    securities;
 
        (4) Make loans, except through loans of portfolio securities or through
    repurchase agreements, provided that for purposes of this limitation, the
    acquisition of bonds, debentures, other debt securities or instruments, or
    participations or other interests therein and investments in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (5) Issue senior securities or borrow money, except as permitted under
    the 1940 Act and then not in excess of 33 1/3% of the Fund's total assets
    (including the amount borrowed but reduced by any liabilities not
    constituting borrowings) at the time of the borrowing, except that the Fund
    may borrow up to an additional 5% of its total assets (not including the
    amount borrowed) for temporary or emergency purposes; or
 
        (6) Purchase or sell physical commodities, but the Fund may purchase,
    sell or enter into financial options and futures, forward and spot currency
    contracts, swap transactions and other financial contracts or derivative
    instruments.
 
Notwithstanding any other investment policy of the Fund, the Fund may invest all
of its investable assets (cash, securities and receivables related to
securities) in an open-end management investment company having substantially
the same investment objective, policies and limitations as the Fund.
 
For purposes of the Fund's concentration policy contained in limitation (1)
above, the Fund intends to comply with the SEC staff positions that securities
issued or guaranteed as to principal and interest by any single foreign
government or any supranational organizations in the aggregate are considered to
be securities of issuers in the same industry.
 
The following investment policies of the Government Income Fund are not
fundamental policies and may be changed by vote of the Company's Board of
Trustees without shareholder approval. The Fund may not:
 
        (1) Borrow money to purchase securities or borrow money except for
    temporary or emergency purposes. While borrowings exceed 5% of the Fund's
    total assets, the Fund will not make any additional investments;
 
        (2) Invest in securities of an issuer if the investment would cause the
    Fund to own more than 10% of any class of securities of any one issuer;

    sales of securities, and further provided that the Fund may make margin
    deposits in connection with its use of financial options and futures,

    contracts or derivative instruments;
 
        (4) Enter into a futures contract, if, as a result thereof, more than 5%
    of the Fund's total assets (taken at market value at the time of entering
    into the contract) would be committed to margin on such futures contracts;
 
        (5) Purchase securities for which there is no readily available market,
    or enter into repurchase agreements or purchase time deposits maturing in
    more than seven days, or purchase OTC options or hold assets set aside to
    cover OTC options written by the Fund, if immediately after and as a result,
    the value of such securities would exceed, in the aggregate, 15% of the
    Fund's net assets; or
 
        (6) Mortgage, pledge, or hypothecate any of its assets, provided that
    this shall not apply to the transfer of securities in connection with any
    permissible borrowing or to collateral arrangements in connection with
    permissible activities.
 
                             STRATEGIC INCOME FUND
 
The Strategic Income Fund may not:

    of the Fund's total assets would be invested in securities of issuers having
    their principal business activities in the same industry, except that this
    limitation does not apply to securities issued or guaranteed by the U.S.

    of issuers that invest in real estate and investments in mortgage-based
    securities, mortgage participations or other instruments supported by
    interests in real estate are not subject to this limitation, and except that
    the Fund may exercise rights under agreements relating to such securities,
    including the right to enforce security interests and to hold real estate
    acquired by reason of such enforcement until that real estate can be
    liquidated in an orderly manner;

    except to the extent that the Fund might be considered an underwriter under
    the federal securities laws in connection with its disposition of portfolio
    securities;
 
        (4) Make loans, except through loans of portfolio securities or through

    acquisition of bonds, debentures, other debt securities or instruments, or
    participations or other interests therein and investments in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;

    securities of an issuer if the investment would cause the Fund to own more

    that the Fund may invest all of its investable assets in an open-end
    management investment company with substantially the same investment
    objectives, policies, and limitations as the Fund.);
 
        (3) Invest more than 10% of its total assets in shares of other
    investment companies and invest more than 5% of its total assets in any one
    investment company or acquire more than 3% of the outstanding voting

    company with substantially the same investment objectives, policies, and

    short-term credits as may be necessary for the clearance of purchases and
    sales of securities, and further provided that the Fund may make margin
    deposits in connection with its use of financial options and futures,
    forward and spot currency contracts, swap transactions and other financial
    contracts or derivative instruments;
 
        (5) Enter into a futures contract, if, as a result thereof, more than 5%
    of the Fund's total assets (taken at market value at the time of entering
    into the contract) would be committed to margin on such futures contracts;
    or
 
        (6) Mortgage, pledge, or hypothecate any of its assets, provided that

                       HIGH INCOME FUND AND THE PORTFOLIO
 
The High Income Fund and the Portfolio each may not:

    of the Fund's total assets would be invested in securities of issuers having
    their principal business activities in the same industry, except that this
    limitation does not apply to securities issued or guaranteed by the U.S.

    the Fund may exercise rights under agreements relating to such securities,
    including the right to enforce security interests and to hold real estate
    acquired by reason of such enforcement until that real estate can be
    liquidated in an orderly manner;

    the federal securities laws in connection with its disposition of portfolio
    securities;

    repurchase agreements, provided that for purposes of this limitation, the
    acquisition of bonds, debentures, other debt securities or instruments, or
    participations or other interests therein and investments in government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan; or

    more than seven days, or purchase OTC options or hold assets set aside to
    cover OTC options written by the Fund, if immediately after and as a result,

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject to policies established by the Trust's and the Portfolio's Board of
Trustees, the Sub-adviser is responsible for the execution of the Government
Income Fund's, the Strategic Income Fund's, the Growth & Income Fund's and the
Portfolio's portfolio transactions and the selection of broker/dealers that
execute such transactions on behalf of these Funds and the Portfolio. In
executing transactions, the Sub-adviser seeks the best net results for the
Government Income Fund, the Strategic Income Fund, the Growth & Income Fund and
the Portfolio, taking into account such factors as the price (including the
applicable brokerage commission or dealer spread), size of the order, difficulty
of execution and operational facilities of the firm involved. Although the
Sub-adviser generally seeks reasonably competitive commission rates and spreads,
payment of the lowest commission or spread is not necessarily consistent with
the best net results. While the Funds and the Portfolio may engage in soft
dollar arrangements for research services, as described below, neither the Funds
nor the Portfolio has any obligation to deal with any broker/dealer or group of
broker/dealers in the execution of portfolio transactions.
    
 
Debt securities generally are traded on a "net" basis with a dealer acting as
principal for its own account without a stated commission, although the price of
the security usually includes a profit to the dealer. U.S. and foreign
government securities and money market instruments generally are traded in the
OTC markets. In underwritten offerings, securities usually are purchased at a
fixed price which includes an amount of compensation to the underwriter. On
occasion, securities may be purchased directly from an issuer, in which case no
commissions or discounts are paid. Broker/dealers may receive commissions on
futures, currency and options transactions.
 
Consistent with the interests of the Funds and the Portfolio, the Sub-adviser
may select brokers to execute the Funds' and the Portfolio's portfolio
transactions on the basis of the research and brokerage services they provide to
the Sub-adviser for its use in managing the Funds and the Portfolio and its
other advisory accounts. Such services may include furnishing analyses, reports
and information concerning issuers, industries, securities, geographic regions,
economic factors and trends, portfolio strategy, and performance of accounts;
and effecting securities transactions and performing functions incidental
thereto (such as clearance and settlement). Research and brokerage services
received from such brokers are in addition to, and not in lieu of, the services
required to be performed by the Sub-adviser under investment management and
administration contracts. A commission paid to such brokers may be higher than
that which another qualified broker would have charged for effecting the same
transaction, provided that the Sub-adviser determines in good faith that such
commission is reasonable in terms either of that particular transaction or the
overall responsibility of the Sub-adviser to the Funds and the Portfolio and its
other clients and that the total commissions paid by the Funds and the Portfolio
will be reasonable in relation to the benefits received by the Funds and the
Portfolio over the long term. Research services may also be received from
dealers who execute Fund transactions in OTC markets.
 
The Sub-adviser may allocate brokerage transactions to broker/dealers who have
entered into arrangements under which the broker/dealer allocates a portion of
the commissions paid by the Funds or the Portfolio toward payment of the Funds'
or the Portfolio's expenses, such as transfer agent and custodian fees.
 
Investment decisions for each Fund and the Portfolio and for other investment
accounts managed by the Sub-adviser are made independently of each other in
light of differing conditions. However, the same investment decision
occasionally may be made for two or more of such accounts, including one or both
Funds and the Portfolio. In such cases, simultaneous transactions may occur.
Purchases or sales are then allocated as to price or amount in a manner deemed
fair and equitable to all accounts involved. While in some cases this practice
could have a detrimental effect upon the price or value of the security as far
as the Funds and the Portfolio are concerned, in other cases the Sub-adviser
believes that coordination and the ability to participate in volume transactions
will be beneficial to the Funds and the Portfolio.
 
   
Under a policy adopted by the Trust's and the Portfolio's Board of Trustees, and
subject to the policy of obtaining the best net results, the Sub-adviser may
consider a broker/dealer's sale of the shares of the Funds and the other funds
for which AIM or the Sub-adviser serves as investment manager in selecting
brokers and dealers for the execution of portfolio

transactions. This policy does not imply a commitment to execute portfolio
transactions through all broker/dealers that sell shares of the Funds and such
other funds.
 
Each Fund and the Portfolio contemplates purchasing most foreign equity
securities in over-the-counter markets or stock exchanges located in the
countries in which the respective principal offices of the issuers of the
various securities are located, if that is the best available market. The fixed
commissions paid in connection with most such foreign stock transactions
generally are higher than negotiated commissions on United States transactions.
There generally is less government supervision and regulation of foreign stock
exchanges and brokers than in the United States. Foreign security settlements
may in some instances be subject to delays and related administrative
uncertainties.
 
Foreign equity securities may be held by a Fund and the Portfolio in the form of
American Depository Receipts ("ADRs"), American Depository Shares ("ADSs"),
Continental Depository Receipts ("CDRs") or European Depository Receipts
("EDRs") or securities convertible into foreign equity securities. ADRs, ADSs,
CDRs and EDRs may be listed on stock exchanges, or traded in the OTC markets in
the United States or Europe, as the case may be. ADRs, like other securities
traded in the United States, will be subject to negotiated commission rates. The
foreign and domestic debt securities and money market instruments in which the
Funds and the Portfolio may invest generally are traded in the OTC markets.
 
   
The Funds and the Portfolio contemplate that, consistent with the policy of
obtaining the best net results, brokerage transactions may be conducted through
certain companies that are affiliates of AIM and the Sub-adviser. The Company's
Board of Trustees has adopted procedures in conformity with Rule 17e-1 under the
1940 Act to ensure that all brokerage commissions paid to such affiliates are
reasonable and fair in the context of the market in which they are operating.
Any such transactions will be effected and related compensation paid only in
accordance with applicable SEC regulations. For the fiscal years ended October
31, 1997, 1996 and 1995, the Portfolio paid aggregate brokerage commissions of
$0, $86,600 and $0, respectively. For the fiscal years ended October 31, 1997,
1996 and 1995, the Government Income Fund paid aggregate brokerage commissions
of $4,987, $24,663 and $0, respectively. For the fiscal years ended October 31,
1997, 1996 and 1995, the Strategic Income Fund paid aggregate brokerage
commissions of $6,177, $85,404 and $0, respectively. For the fiscal years ended
October 31, 1997, 1996, and 1995, the Growth & Income Fund paid aggregate
brokerage commissions of $463,307, $257,953 and $318,958, respectively. For the
fiscal years ended October 31, 1996 and 1997, the Growth & Income Fund paid to
LGT Bank in Liechtenstein, AG, which was an "affiliated" broker, aggregate
brokerage commissions of $16,898 and $12,262, respectively, for transactions
involving purchases and sales of portfolio securities which represented 6.55%
and 2.65%, respectively, of the total brokerage commissions paid by the Fund and
5.69% and 2.94%, respectively, of the aggregate dollar amount of transactions
involving payment of commissions by the Fund.
    
 
PORTFOLIO TRADING AND TURNOVER
   
Each Fund and the Portfolio engages in portfolio trading when the Sub-adviser
concludes that the sale of a security owned by a Fund and the Portfolio and/or
the purchase of another security of better value can enhance principal and/or
increase income. A security may be sold to avoid any prospective decline in
market value, or a security may be purchased in anticipation of a market rise.
Consistent with each Fund's and the Portfolio's investment objectives, a
security also may be sold and a comparable security purchased coincidentally in
order to take advantage of what is believed to be a disparity in the normal
yield and price relationship between the two securities. Although the Funds and
the Portfolio generally do not intend to trade for short-term profits, the
securities in each Fund's and the Portfolio's portfolio will be sold whenever
the Sub-adviser believes it is appropriate to do so, without regard to the
length of time a particular security may have been held. Portfolio turnover is
calculated by dividing the lesser of sales or purchases of portfolio securities
by each Fund's or the Portfolio's average month-end portfolio value, excluding
short-term investments. Higher portfolio turnover involves correspondingly
greater brokerage commissions and other transaction costs that a Fund or the
Portfolio will bear directly, and could result in the realization of net capital
gains that would be taxable when distributed to shareholders. The portfolio
turnover rates for the Government Income Fund, Strategic Income Fund, Growth &
Income Fund and the Portfolio the last two fiscal years were as follows:

Growth & Income Fund's investment manager and administrator under an investment
management and administration contract between the Trust and AIM ("Trust
Management Contract"). The Sub-adviser serves as the Portfolio's sub-adviser and
sub-administrator under a sub-advisory and sub-administration Agreement between
AIM and the Sub-adviser ("Portfolio Management Sub-Contract," and together with
the Portfolio Management Contract, the "Portfolio Management Contracts"). AIM
serves as the Portfolio's investment manager and administrator under an
Investment Management and Administration Contract between the Portfolio and AIM
("Portfolio Management Contract") (collectively, "Management Contracts"). The
Sub-adviser serves as sub-administrator to each Feeder Fund under a
sub-administration contract between AIM and the Sub-adviser ("Administration
Sub-Contract," and together with the Administration Contract, the
"Administration Contracts"). AIM serves as the High Income Fund's administrator
under an Administration Contract ("Administration Contract") between the Trust
and AIM. The Sub-adviser serves as the sub-adviser and sub-administrator to the
Government Income Fund, the Strategic Income Fund and the Growth & Income Fund
under a sub-advisory and sub-administration Contract between AIM and the
Sub-adviser ("Sub-Management Contract," and together with the Management
Contract, the "Management Contracts"). The Administration Contracts will not be
deemed advisory contracts, as defined under the 1940 Act. As investment managers
and administrators, AIM and the Sub-adviser make all investment decisions for
the Government Income Fund, the Strategic Income Fund, the Growth & Income Fund
and the Portfolio and as administrators, AIM and the Sub-adviser administer each
Fund's and the Portfolio's affairs. Among other things, AIM and the Sub-adviser
furnish the services and pay the compensation and travel expenses of persons who
perform the executive, administrative, clerical and bookkeeping functions of the
Trust, the Funds, and the Portfolio and provide suitable office space, necessary
small office equipment and utilities.
    
 
   
The Management Contracts may be renewed for one-year terms, provided that any
such renewal has been specifically approved at least annually by: (i) the
Trust's or the Portfolio's Board of Trustees, as applicable, or by the vote of a
majority of the Fund's or the Portfolio's outstanding voting securities (as
defined in the 1940 Act), and (ii) a majority of Trustees who are not parties to
the Management Contracts or the Administration Contracts or "interested persons"
of any such party (as defined in the 1940 Act), cast in person at a meeting
called for the specific purpose of voting on such approval. The Management
Contracts provide that with respect to the Government Income Fund, the Strategic
Income Fund, the Growth & Income Fund and the Portfolio, and the Administration
Contracts provide that with respect to the High Income Fund, either the Trust,
the Portfolio or each of AIM or the Sub-adviser may terminate the Contracts
without penalty upon sixty days' written notice to the other party. The
Management Contracts and the Administration Contracts terminate automatically in
the event of their assignment (as defined in the 1940 Act).

DISTRIBUTION SERVICES
   
Each Fund's Advisor Class shares are offered continuously through each Fund's
principal underwriter and distributor, AIM Distributors, on a "best efforts"
basis pursuant to a distribution contract between the Trust and AIM Distributors
without a sales charge or a contingent deferred sales charge.
    
 
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The Transfer Agency and Service Agreement between the Trust and A I M Fund
Services, Inc. ("AFS"), a registered transfer agent and wholly-owned subsidiary
of AIM, provides that AFS will perform certain shareholder services for the
Funds for a fee per account serviced. The Transfer Agency and Service Agreement
provides that AFS will receive a per account fee plus out-of-pocket expenses to
process orders for purchases, redemptions and exchanges of shares; prepare and
transmit payments for dividends and distributions declared by the Funds;
maintain shareholder accounts and provide shareholders with information
regarding the Funds and their accounts. The Transfer Agency and Service
Agreement became effective on September 8, 1998. The Sub-adviser also serves as
each Fund's pricing and accounting agent. As of October 31, 1997, October 31,
1996 and October 31, 1995, the Fund paid accounting services fees to the
Sub-adviser of Government Income Fund, Strategic Income Fund, High Income Fund
and Growth & Income Fund of $85,149, $127,205, $40,218 and $183,323; $123,309,
$131,517, $34,980 and $162,035; and $116,607, $101,697, $22,563 and $40,735,
respectively.
    
 
EXPENSES OF THE FUNDS AND THE PORTFOLIO
   
Each Fund and the Portfolio pays all expenses not assumed by AIM, the
Sub-adviser, AIM Distributors and other agents. These expenses include, in
addition to the advisory, distribution, transfer agency, pricing and accounting
agent and brokerage fees discussed above, legal and audit expenses, custodian
fees, trustees' fees, organizational fees, fidelity bond and other insurance
premiums, taxes, extraordinary expenses and the expenses of reports and
prospectuses sent to existing investors. The allocation of general Company
expenses and expenses shared by the Funds and other funds organized as series of
the Trust are allocated on a basis deemed fair and equitable, which may be based
on the relative net assets of the Funds or the nature of the services performed
and relative applicability to each Fund. Expenditures, including costs incurred
in connection with the purchase or sale of portfolio securities, which are
capitalized in accordance with generally accepted accounting principles
applicable to investment companies, are accounted for as capital items and

                        AIM GLOBAL GROWTH & INCOME FUND
not as expenses. The ratio of each Fund's and the Portfolio's expenses to its
relative net assets can be expected to be higher than the expense ratios of
funds investing solely in domestic securities, since the cost of maintaining the
custody of foreign securities and the rate of investment management fees paid by
each Fund and the Portfolio generally are higher than the comparable expenses of
such other funds.
 
- --------------------------------------------------------------------------------
 
                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
   
The net asset value per share of each Fund and Portfolio is normally determined
daily as of the close of trading of the New York Stock Exchange ("NYSE")
(generally 4:00 p.m. Eastern time) on each business day of the Fund and
Portfolio. In the event the NYSE closes early (i.e., before 4:00 p.m. Eastern
time) on a particular day, the net asset value of a Fund or Portfolio is
determined as of the close of the NYSE on such day. Net asset value per share is
determined by dividing the value of a Fund's or the Portfolio's securities, cash
and other assets (including interest accrued but not collected) attributable to
a particular class, less all its liabilities (including accrued expenses and
dividends payable) attributable to that class, by the total number of shares
outstanding of that class. Determination of a Fund's or the Portfolio's net
asset value per share is made in accordance with generally accepted accounting
principles.
    
 
   
Each equity security is valued at its last sales price on the exchange where the
security is principally traded or, lacking any sales on a particular day, the
security is valued at the mean between the closing bid and asked prices on that
day. Each security traded in the over-the-counter market (but not including
securities reported on the NASDAQ National Market System) is valued at the mean
between the last bid and asked prices based upon quotes furnished by market
makers for such securities. Each security reported on the NASDAQ National Market
System is valued at the last sales price on the valuation date or absent a last
sales price, at the mean between the closing bid and asked prices on that day.
Debt securities are valued on the basis of prices provided by an independent
pricing service. Prices provided by the pricing service may be determined
without exclusive reliance on quoted prices, and may reflect appropriate factors
such as institution-size trading in similar groups of securities, developments
related to special securities, yield, quality, coupon rate, maturity, type of
issue, individual trading characteristics and other market data. Securities for
which market quotations are not readily available or are questionable are valued
at fair value as determined in good faith by or under the supervision of the
Trust's officers in a manner specifically authorized by the Board of Trustees.
Short-term obligations having 60 days or less to maturity are valued on the
basis of amortized cost. For purposes of determining net asset value per share,
futures and options contracts generally will be valued 15 minutes after the
close of trading of the NYSE.
    
 
   
Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of each Fund's or Portfolio's shares are
determined at such times. Foreign currency exchange rates are also generally
determined prior the close of the NYSE. Occasionally, events affecting the
values of such securities and such exchange rates may occur between the times at
which such values are determined and the close of the NYSE which will not be
reflected in the computation of a Fund's or Portfolio's net asset value. If
events materially affecting the value of such securities occur during such
period, then these securities will be valued at their fair value as determined
in good faith by or under the supervision of the Board of Trustees of the Fund.

A complete description of the manner in which shares of the Funds may be
purchased appears in the Funds' Prospectuses under the headings "How to Purchase
Shares," "Terms and Conditions of Purchase of the AIM Funds" and "Special
Plans."
    
 
   
For purposes of a Letter of Intent entered into prior to June 1, 1998, any
registered investment adviser, trust company or bank trust department which
exercises investment discretion and which intends within thirteen months to
invest $500,000 or more can be treated as a single purchaser, provided further
that such entity places all purchases and redemption orders. Such entities
should be prepared to establish their qualifications for such treatment.
    
 
   
Complete information concerning the method of exchanging shares of the Funds for
shares of the other AIM Funds is set forth in the Prospectuses under the heading
"Exchange Privilege."
    
 
   
Information concerning redemption of the Funds' shares is set forth in the
Prospectuses under the heading "How to Redeem Shares." In addition to the Funds'
obligation to redeem shares, AIM Distributors may also repurchase shares as an
accommodation to shareholders. To effect a repurchase, those dealers who have
executed Selected Dealer Agreements with AIM Distributors must phone orders to
the order desk of the Funds at (800) 959-4246 and guarantee delivery of all
required documents in good order. A repurchase is effected at the net asset
value per share of the applicable Fund next determined after the repurchase
order is received. Such an arrangement is subject to timely receipt by A I M
Fund Services, Inc., the Funds' transfer agent, of all required documents in
good order. If such documents are not received within a reasonable time after
the order is placed, the order is subject to cancellation. While there is no
charge imposed by a Fund or by AIM Distributors (other than any applicable
contingent deferred sales charge) when shares are redeemed or repurchased,
dealers may charge a fair service fee for handling the transaction.
    
 
   
The right of redemption may be suspended or the date of payment postponed when
(a) trading on the NYSE is restricted, as determined by applicable rules and
regulations of the SEC, (b) the NYSE is closed for other than customary weekend
and holiday closings, (c) the SEC has by order permitted such suspension, or (d)
an emergency as determined by the SEC exists making disposition of portfolio
securities or the valuation of the net assets of a Fund not reasonably
practicable.
    
 
   
PROGRAMS AND SERVICES FOR SHAREHOLDERS. The Funds provide certain services for
shareholders and certain investment or redemption programs. See "Exchange
Privilege" and "How to Redeem Shares" in the Prospectus. All inquiries
concerning these programs should be made directly to A I M Fund Services, Inc.,
P.O. Box 4739, Houston, Texas 77210-4739, toll free at (800) 959-4246.
    
 
   
DIVIDEND ORDER. Dividends may be paid to someone other than the registered
owner, or sent to an address other than the address of record. (Please note that
signature guarantees are required to effect this option.) An investor also may
direct that his or her dividends be invested in one of the other A I M Funds and
there is no sales charge for these investments; initial investment minimums
apply. See "Dividends, Distributions and Tax Matters -- Dividends and
Distributions" in the Prospectus. To effect this option, please contact your
authorized dealer. For more information concerning AIM Funds other than the
Funds, please obtain a current prospectus by contacting your authorized dealer,
by writing to A I M Fund Services, Inc., P.O. Box 4739, Houston, Texas

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUNDS
Each Fund is treated as a separate corporation for federal income tax purposes.
To continue to qualify for treatment as a regulated investment company ("RIC")
under the Code, each Fund must distribute to its shareholders for each taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income, net short-term capital gain and net gains from certain
foreign currency transactions) ("Distribution Requirement") and must meet
several additional requirements. With respect to each Fund, these requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each taxable year from dividends, interest, payments with respect to securities
loans and gains from the sale or other disposition of securities or foreign
currencies, or other income (including gains from options, Futures or Forward
Contracts) derived with respect to its business of investing in securities or
those currencies ("Income Requirement"); (2) at the close of each quarter of the
Fund's taxable year, at least 50% of the value of its total assets must be
represented by cash and cash items, U.S. government securities, securities of
other RICs and other securities, with these other securities limited, in respect
of any one issuer, to an amount that does not exceed 5% of the value of the
Fund's total assets and that does not represent more than 10% of the issuer's
outstanding voting securities; and (3) at the close of each quarter of the
Fund's taxable year, not more than 25% of the value of its total assets may be
invested in securities (other than U.S. government securities or the securities
of other RICs) of any one issuer. The High Income Fund, as an investor in the
Portfolio, is deemed to own a proportionate share of the Portfolio's assets, and
to earn a proportionate share of the Portfolio's income, for purposes of
determining whether that Fund satisfies the requirements described above to
qualify as a RIC.
 
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent it fails to distribute by the end of any calendar year substantially all
of its ordinary income for that year and capital gain net income for the
one-year period ending on October 31 of that year, plus certain other amounts.
 
See "Taxation of Certain Investment Activities" below for a discussion of the
tax consequences to the High Income Fund of hedging transactions engaged in, and
investments in passive foreign investment companies ("PFICs") and other foreign
securities by, the Portfolio.
 
TAXATION OF THE PORTFOLIO -- GENERAL
The Portfolio is treated as a partnership for federal income tax purposes and is
not a "publicly traded partnership." As a result, the Portfolio is not subject
to federal income tax; instead, the High Income Fund, as an investor in the
Portfolio, is required to take into account in determining its federal income
tax liability its share of the Portfolio's income, gains, losses, deductions and
credits, without regard to whether it has received any cash distributions from
the Portfolio. The Portfolio also is not subject to Delaware income or franchise
tax.
 
Because, as noted above, the High Income Fund is deemed to own a proportionate
share of the Portfolio's assets, and to earn a proportionate share of the
Portfolio's income, for purposes of determining whether that Fund satisfies the
requirements to qualify as a RIC, the Portfolio intends to conduct its
operations so that the High Income Fund will be able to continue to satisfy all
those requirements.
 
Distributions to the High Income Fund from the Portfolio (whether pursuant to a
partial or complete withdrawal or otherwise) will not result in that Fund's
recognition of any gain or loss for federal income tax purposes, except that (1)
gain will be recognized to the extent any cash that is distributed exceeds that
Fund's basis for its interest in the Portfolio before the distribution, (2)
income or gain will be recognized if the distribution is in liquidation of that
Fund's entire interest in the Portfolio and includes a disproportionate share of
any unrealized receivables held by the Portfolio, and (3) loss will be
recognized if a liquidation distribution consists solely of cash and/or
unrealized receivables. The High Income Fund's basis for its interest in the
Portfolio generally will equal the amount of cash and the basis of any property
that Fund invests in the Portfolio, increased by that Fund's share of the
Portfolio's net income and gains and decreased by (a) the amount of cash and the
basis of any property the Portfolio distributes to that Fund and (b) that Fund's
share of the Portfolio's losses.

TAXATION OF CERTAIN INVESTMENT ACTIVITIES
   
For purposes of the following discussion, "Investor Funds" means the Government
Income Fund, the Strategic Income Fund, the Growth & Income Fund and the
Portfolio.
    
 
   
    FOREIGN TAXES. Interest and dividends received by an Investor Fund, and
gains realized thereby, may be subject to income, withholding or other taxes
imposed by foreign countries and U.S. possessions ("foreign taxes") that would
reduce the yield and/or total return on its securities. Tax conventions between
certain countries and the United States may reduce or eliminate foreign taxes,
however, and many foreign countries do not impose taxes on capital gains in
respect of investments by foreign investors. If more than 50% of the value of an
Investor Fund's total assets (taking into account, in the case of the High
Income Fund, its proportionate share of the Portfolio's assets) at the close of
its taxable year consists of securities of foreign corporations, the Fund will
be eligible to, and may, file an election with the Internal Revenue Service that
will enable its shareholders, in effect, to receive the benefit of the foreign
tax credit with respect to any foreign taxes paid by it (taking into account, in
the case of the High Income Fund, its proportionate share of any foreign taxes
paid by the Portfolio) (a "Fund's foreign taxes"). Pursuant to the election, an
Investor Fund would treat those taxes as dividends paid to its shareholders and
each shareholder would be required to (1) include in gross income, and treat as
paid by him, his proportionate share of the Fund's foreign taxes, (2) treat his
share of those taxes and of any dividend paid by the Fund that represents its
income from foreign and U.S. possessions sources (taking into account, in the
case of the High Income Fund, its proportionate share of the Portfolio's income
from those sources) as his own income from those sources and (3) either deduct
the taxes deemed paid by him in computing his taxable income or, alternatively,
use the foregoing information in calculating the foreign tax credit against his
federal income tax. Each Investor Fund will report to its shareholders shortly
after each taxable year their respective shares of the Fund's foreign taxes and
income (taking into account, in the case of the High Income Fund, its
proportionate share of the Portfolio's income) from sources within foreign
countries and U.S. possessions if it makes this election. Pursuant to the
Taxpayer Relief Act of 1997 ("Tax Act"), individuals who have no more than $300
($600 for married persons filing jointly) of creditable foreign taxes included
on Form 1099 and all of whose foreign source income is "qualified passive
income" may elect each year to be exempt from the extremely complicated foreign
tax credit limitation and will be able to claim a foreign tax credit without
having to file the detailed Form 1116 that otherwise is required.
    
 
   
    PASSIVE FOREIGN INVESTMENT COMPANIES. Each Investor Fund may invest in the
stock of PFICs. A PFIC is a foreign corporation -- other than a "controlled
foreign corporation" (I.E., a foreign corporation in which, on any day during
its taxable year, more than 50% of the total voting power of all voting stock
therein or the total value of all stock therein is owned, directly, indirectly
or constructively, by "U.S. shareholders," defined as U.S. persons that
individually own, directly, indirectly or constructively, at least 10% of that
voting power) as to which the Investor Fund is a U.S. shareholder (effective
with respect to each Investor Fund for its taxable year beginning November 1,
1998) -- that, in general, meets either of the following tests: (1) at least 75%
of its gross income is passive or (2) an average of at least 50% of its assets
produce, or are held for the production of, passive income. Under certain
circumstances, an Investor Fund will be subject to federal income tax on a part
(or, in the case of the High Income Fund, its proportionate share of a part) of
any "excess distribution" received by it (or, in the case of the High Income
Fund, by the Portfolio) on the stock of a PFIC or of any gain on the Fund's (or,
in the case of the High Income Fund, the Portfolio's) disposition of that stock
(collectively "PFIC income"), plus interest thereon, even if the Fund
distributes the PFIC income as a taxable dividend to its shareholders. The
balance of the PFIC income will be included in the Fund's investment company
taxable income and, accordingly, will not be taxable to it to the extent it
distributes that income to its shareholders.
    
 
If an Investor Fund invests in a PFIC and elects to treat the PFIC as a
"qualified electing fund" ("QEF"), then in lieu of the foregoing tax and
interest obligation, the Investor Fund (or, in the case of the Portfolio, the
High Income Fund) would be required to include in income each year its pro rata
share (taking into account, in the case of the High Income Fund, its
proportionate share of the Portfolio's pro rata share) of the QEF's ordinary
earnings and net capital gain (I.E., the excess of net long-term capital gain
over net short-term capital loss) -- which most likely would have to be
distributed by the Investor Fund (or, in the case of the Portfolio, the High
Income Fund) to satisfy the Distribution Requirement and avoid imposition of the
Excise Tax -- even if those earnings and gain were not received thereby from the
QEF. In most instances it will be very difficult, if not impossible, to make
this election because of certain requirements thereof.
 
   
Effective for its taxable year beginning November 1, 1998, each Investor Fund
may elect to "mark to market" its stock in any PFIC. "Marking-to-market," in
this context, means including in ordinary income each taxable year the excess,
if any, of the fair market value of the stock over an Investor Fund's adjusted
basis therein as of the end of that year. Pursuant to
    
 
                  Statement of Additional Information Page 40

the election, an Investor Fund also will be allowed to deduct (as an ordinary,
not capital, loss) the excess, if any, of its adjusted basis in PFIC stock over
the fair market value thereof as of the taxable year-end, but only to the extent
of any net mark-to-market gains with respect to that stock included in income by
the Fund for prior taxable years. An Investor Fund's adjusted basis in each
PFIC's stock subject to the election will be adjusted to reflect the amounts of
income included and deductions taken thereunder. Regulations proposed in 1992
provided a similar election with respect to the stock of certain PFICs.
    
 
    OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. The Investors Funds' use
of hedging transactions, such as selling (writing) and purchasing options and
Futures Contracts and entering into Forward Contracts, involves complex rules
that will determine, for federal income tax purposes, the amount, character and
timing of recognition of the gains and losses an Investor Fund realizes in
connection therewith. Gains from the disposition of foreign currencies (except
certain gains that may be excluded by future regulations), and gains from
options, Futures and Forward Contracts derived by an Investor Fund with respect
to its business of investing in securities or foreign currencies, will qualify
as permissible income under the Income Requirement for that Investor Fund (or,
in the case of the Portfolio, the High Income Fund).
 
Futures and Forward Contracts that are subject to Section 1256 of the Code
(other than those that are part of a "mixed straddle") ("Section 1256
Contracts") and that are held by an Investor Fund at the end of its taxable year
generally will be deemed to have been sold at that time at market value for
federal income tax purposes. Sixty percent of any net gain or loss recognized on
these deemed sales, and 60% of any net gain or loss realized from any actual
sales of Section 1256 Contracts, will be treated as long-term capital gain or
loss, and the balance will be treated as short-term capital gain or loss. That
60% portion will qualify for the reduced maximum tax rates on noncorporate
taxpayers' net capital gain enacted by the Tax Act -- 20% (10% for taxpayers in
the 15% marginal tax bracket) for gain recognized on capital assets held for
more than 18 months -- instead of the 28% rate in effect before that
legislation, which now applies to gain recognized on capital assets held for
more than one year but not more than 18 months.
 
Section 988 of the Code also may apply to gains and losses from transactions in
foreign currencies, foreign-currency-denominated debt securities and options,
Futures and Forward Contracts on foreign currencies ("Section 988" gains and
losses). Each Section 988 gain or loss generally is computed separately and
treated as ordinary income or loss. In the case of overlap between sections 1256
and 988, special provisions determine the character and timing of any income,
gain or loss. Each Investor Fund attempts to monitor section 988 transactions to
minimize any adverse tax impact.
 
   
If an Investor Fund has an "appreciated financial position" -- generally, an
interest (including an interest through an option, Futures or Forward Contract
or short sale) with respect to any stock, debt instrument (other than "straight
debt") or partnership interest the fair market value of which exceeds its
adjusted basis -- and enters into a "constructive sale" of the same or
substantially similar property, the Fund will be treated as having made an
actual sale thereof, with the result that gain will be recognized at that time.
A constructive sale generally consists of a short sale, an offsetting notional
principal contract or Futures or Forward Contract entered into by an Investor
Fund or a related person with respect to the same or substantially similar
property. In addition, if the appreciated financial position is itself a short
sale or such a contract, acquisition of the underlying property or substantially
similar property will be deemed a constructive sale.
    
 
   
The Strategic Income Fund and the Portfolio each may acquire zero coupon or
other securities issued with original issue discount ("OID"). As a holder of
those securities, that Fund and the Portfolio (and, through it, the High Income
Fund) each must include in its income the portion of the OID that accrues on the
securities during the taxable year, even if no corresponding payment on them is
received during the year. Similarly, the Strategic Income Fund and the Portfolio
each must include in its gross income securities it receives as "interest" on
payment-in-kind securities. Because each Fund annually must distribute
substantially all of its investment company taxable income, including any OID
and other non-cash income, to satisfy the Distribution Requirement and avoid
imposition of the Excise Tax, the Strategic Income Fund or the High Income Fund,
or both, may be required in a particular year to distribute as a dividend an
amount that is greater than the total amount of cash it actually receives (or,
in the case of the High Income Fund, its share of the total amount of cash the
Portfolio actually receives). Those distributions will be made from the Fund's
(or, in the case of the High Income Fund, its, or its share of the Portfolio's)
cash assets or, if necessary, from the proceeds of sales of portfolio
securities. A Fund may (directly or through the Portfolio) realize capital gains
or losses from those sales, which would increase or decrease its investment
company taxable income and/or net capital gain.

TAXATION OF THE FUNDS' SHAREHOLDERS
Dividends and other distributions declared by a Fund in, and payable to
shareholders of record as of a date in, October, November or December of any
year will be deemed to have been paid by the Fund and received by the
shareholders on December 31 of that year if the distributions are paid by the
Fund during the following January. Accordingly, those distributions will be
taxed to shareholders for the year in which that December 31 falls.
 
   
A portion of the dividends from the Growth & Income Fund's investment company
taxable income (whether paid in cash or reinvested in additional shares) may be
eligible for the dividends-received deduction allowed to corporations. The
eligible portion may not exceed the aggregate dividends received by that Fund
from U.S. corporations. However, dividends received by a corporate shareholder
and deducted by it pursuant to the dividends-received deduction are subject
indirectly to the federal alternative minimum tax. The Funds other than the
Growth & Income Fund are not expected to pay dividends eligible for that
deduction.
    
 
If Fund shares are sold at a loss after being held for six months or less, the
loss will be treated as long-term, instead of short-term, capital loss to the
extent of any capital gain distributions received on those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or other distribution, the shareholder will pay full price for
the shares and receive some portion of the price back as a taxable distribution.
 
Dividends paid by a Fund to a shareholder who, as to the United States, is a
nonresident alien individual, nonresident alien fiduciary of a trust or estate,
foreign corporation or foreign partnership ("foreign shareholder") generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply, however, to a dividend paid by a Fund to a foreign
shareholder that is "effectively connected with the conduct of a U.S. trade or
business," in which case the reporting and withholding requirements applicable
to domestic shareholders will apply. A distribution of net capital gain by a
Fund to a foreign shareholder generally will be subject to U.S. federal income
tax (at the rates applicable to domestic persons) only if the distribution is
"effectively connected" or the foreign shareholder is treated as a resident
alien individual for federal income tax purposes.
 
The foregoing is a general and abbreviated summary of certain federal tax
considerations affecting the Funds, their shareholders and the Portfolio.
Investors are urged to consult their own tax advisers for more detailed
information and for information regarding any foreign, state and local taxes
applicable to distributions received from a Fund.

SHAREHOLDER LIABILITY
    
   
Under Delaware law, the shareholders of the Trust enjoy the same limitations
extended to shareholders of private, for-profit corporations. There is a remote
possibility, however, that under certain circumstances shareholders of the Trust
may be held personally liable for the Trust's obligations. However, the Trust
Agreement disclaims shareholder liability for acts or obligations of the Trust
and requires that notice of such disclaimer be given in each agreement,
obligation or instrument entered into or executed by the Trust or a trustee. The
Trust Agreement provides for indemnification from the Trust property for all
losses and expenses of any shareholder held personally liable for the Trust's
obligations. Thus, the risk of a shareholder incurring financial loss on account
of such liability is limited to circumstances in which the Trust itself would be
unable to meet its obligations and where the other party was held not to be
bound by the disclaimer.

TOTAL RETURN QUOTATIONS
    
   
The standard formula for calculating total return, as described in the
Prospectus, is as follows:
    
 
   
                          P(1+T)to the power of n=ERV
    
 
   
<TABLE>
<S>        <C>        <C>
Where      P   =      a hypothetical initial payment of $1,000.
           T   =      average annual total return (assuming the applicable maximum sales load is deducted at
                      the beginning of the 1, 5, or 10 year periods).
           n   =      number of years.
           ERV =      ending redeemable value of a hypothetical $1,000 payment at the end of the 1, 5, or 10
                      year periods (or fractional portions of such period).

NON-STANDARDIZED RETURNS
   
Standard total return quotes may be accompanied by total return figures
calculated by alternative methods. For example, average annual total return may
be calculated without assuming payment of the full sales load according to the
following formula:
    
 
   
                          P(1+U)to the power of n=ERV
    
 
   
<TABLE>

Where      P   =      a hypothetical initial payment of $1,000.
           U   =      average annual total return assuming payment of only a stated portion of, or none of, the
                      applicable maximum sales load at the beginning of the stated period.
           n   =      number of years.
           ERV =      ending redeemable value of a hypothetical $1,000 payment at the end of the stated period.
</TABLE>
    
 
   
Cumulative total return across a stated period may be calculated as follows:
    
 
   
                          P(1+V)to the power of n=ERV

                      applicable maximum sales load at the beginning of the stated period.
           n   =      number of years.

YIELD QUOTATIONS
    
   
The standard formula for calculating yield for each Fund, as described in the
Prospectus, is as follows:
    
 
   
                 YIELD = 2[((a-b)/(cXd)+1)to the power of 6-1]
    
 
   
<TABLE>
<S>        <C>        <C>
Where      a =        dividends and interest earned during a stated 30-day period. For purposes of this
                      calculation, dividends are accrued rather than recorded on the ex-dividend date. Interest
                      earned under this formula must generally be calculated based on the yield to maturity of
                      each obligation (or, if more appropriate, based on yield to a call date).
           b =        expenses accrued during period (net of reimbursement).
           c =        the average daily number of shares outstanding during the period.
           d =        the maximum offering price per share on the last day of the period.
</TABLE>
    
 
   
The Yields of the Class A shares of the Strategic Income Fund, Government Income
Fund and the High Income Fund for the one-month period ended October 31, 1996
were [6.58%, 6.23% and 7.29%], respectively. The current yields of the Class B
shares of Strategic Income Fund, Government Income Fund and High Income Fund for
the one-month period ended October 31, 1996 were [6.23%, 5.87% and 7.00%],
respectively. The Yields of the Advisor Class shares of the Strategic Income
Fund, Government Income Fund and High Income Fund for the one-month period ended
October 31, 1996 were 7.27%, 6.74% and 8.04%, respectively.

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF BOND RATINGS
    MOODY'S INVESTORS SERVICE, INC. rates the debt securities issued by various
entities from "Aaa" to "C". Investment grade ratings are the first four
categories:
 
        Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
    They carry the smallest degree of investment risk and are generally referred
    to as "gilt edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.
 
        Aa -- Bonds which are rated Aa are judged to be of high quality by all
    standards. Together with the Aaa group they comprise what are generally
    known as high grade bonds. They are rated lower than the best bonds because
    margins of protection may not be as large as in Aaa securities or
    fluctuation of protective elements may be of greater amplitude or there may
    be other elements present which make the long-term risk appear somewhat
    larger than the Aaa securities.
 
        A -- Bonds which are rated A possess many favorable investment
    attributes and are to be considered as upper-medium-grade obligations.
    Factors giving security to principal and interest are considered adequate,
    but elements may be present which suggest a susceptibility to impairment
    some time in the future.
 
        Baa -- Bonds which are rated Baa are considered as medium-grade
    obligations, (i.e., they are neither highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective elements may be lacking or may be characteristically
    unreliable over any great length of time. Such bonds lack outstanding
    investment characteristics and in fact have speculative characteristics as
    well.
 
        Ba -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered as well-assured. Often the protection of
    interest and principal payments may be very moderate, and thereby not well
    safeguarded during both good and bad times over the future. Uncertainty of
    position characterizes bonds in this class.
 
        B -- Bonds which are rated B generally lack characteristics of the
    desirable investment. Assurance of interest and principal payments or of
    maintenance of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa are of poor standing. Such issues may
    be in default or there may be present elements of danger with respect to
    principal or interest.
 
        Ca -- Bonds which are rated Ca represent obligations which are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C -- Bonds which are rated C are the lowest rated class of bonds, and
    issues so rated can be regarded as having extremely poor prospects of ever
    attaining any real investment standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
     1. An application for rating was not received or accepted.
 
     2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
     3. There is a lack of essential data pertaining to the issue or issuer.
 
   
     4. The issue was privately placed, in which case the rating is not
published in Moody's publications.

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers, 1, 2, and 3 in each generic rating
classification from Aa to Caa. The modifier 1 indicates that the Company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a division of The McGraw-Hill Companies, Inc., rates the
securities debt of various entities in categories ranging from "AAA" to "D"
according to quality. Investment grade ratings are the first four categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA -- An obligation rated "AA" differs from the highest rated
    obligations only in a small degree. The obligor's capacity to meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB -- An obligation rated "BBB" exhibits adequate protection
    parameters. However, adverse economic conditions or changing circumstances
    are more likely to lead to a weakened capacity of the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations rated "BB," "B," "CCC," "CC," and "C"
    are regarded as having significant speculative characteristics. "BB"
    indicates the least degree of speculation and "C" the highest. While such
    obligations will likely have some quality and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An obligation rated "BB" is less vulnerable to nonpayment than
    other speculative issues. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate capacity to meet its financial commitment
    on the obligation.
 
        B -- An obligation rated "B" is more vulnerable to nonpayment than
    obligations rated "BB," but the obligor currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its financial commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to have the capacity to meet its financial commitment on the
    obligation.
 
        CC -- An obligation rated "CC" is currently highly vulnerable to
    nonpayment.
 
        C -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed or similar action has been taken, but payments on
    this obligation are being continued.
 
        D -- An obligation rated "D" is in payment default. The "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the applicable grace period has not expired, unless S&P believes
    that such payments will be made during such grace period. The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
NR: Indicates that no rating has been requested, that there is insufficient
information on which to base a rating, or that S&P does not rate a particular
type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
   
    MOODY'S employs the designation "Prime-1" to indicate commercial paper
having a superior ability for repayment of senior short-term debt obligations.
Prime-1 repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative

                          AIM GLOBAL HIGH INCOME FUND
                        AIM GLOBAL GROWTH & INCOME FUND
capitalization structure with moderate reliance on debt and ample asset
protection; broad margins in earnings coverage of fixed financial charges and
high internal cash generation; and well-established access to a range of
financial markets and assured sources of alternate liquidity. Issues rated
Prime-2 have a strong ability for repayment of senior short-term debt
obligations. This normally will be evidenced by many of the characteristics
cited above but to a lesser degree. Earnings trends and coverage ratios, while
sound, may be more subject to variation. Capitalization characteristics, while
still appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.
 
    S&P ratings of commercial paper are graded into several categories ranging
from "A1" for the highest quality obligations to "D" for the lowest. Issues in
the "A" category are delineated with numbers 1, 2, and 3 to indicate the
relative degree of safety. A-1 -- This highest category indicates that the
degree of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation. A-2 -- Capacity for timely payments on issues with this
designation is satisfactory; however, the relative degree of safety is not as
high as for issues designated "A-1."

ITEM 27. INDEMNIFICATION
    
 
   
    Article VII(g) of  the Registrant's Articles  of Incorporation provides  for
indemnification of certain persons acting on behalf of the Registrant.
    
 
   
    Insofar  as indemnification for liabilities arising under the Securities Act
of 1933, as amended  ("1933 Act"), may be  permitted to Directors, Officers  and
Controlling  Persons by the Registrant's  Articles of Incorporation, By-Laws, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange  Commission  such  indemnification  is  against  public  policy  as
expressed in the 1933 Act, and is, therefore, unenforceable. In the event that a
claim  for indemnification against  such liabilities (other  than the payment by
the  Registrant  of  expenses  incurred  or  paid  by  a  Director,  Officer  or
Controlling  Person of the  Registrant in the successful  defense of any action,
suit or proceeding) is asserted by such Director, Officer or Controlling  Person
in  connection with the securities being registered, the Registrant will, unless
in the  opinion  of its  counsel  the matter  has  been settled  by  controlling
precedent,  submit to a  court of appropriate  jurisdiction the question whether
such indemnification by it is against public policy as expressed in the 1933 Act
and will be governed by the final adjudication of such issues.

               (b)  shall be responsible and liable for all losses, damages and
     costs (including reasonable attorneys' fees) incurred by the Company or any

     performance of its duties under this Agreement or for INVESCO (NY)'s
     negligent failure to perform such duties as are specifically assumed by
     INVESCO (NY) in this Agreement, provided that, to the extend that duties,
     obligations and responsibilities are not expressly set forth in this
     Agreement, INVESCO (NY) shall not be liable for any act or omission that
     does not constitute willful misfeasance, bad faith or negligence on the
     part of INVESCO (NY) or reckless disregard by INVESCO (NY) of such duties,
     obligations and responsibilities; and

               (c)  without limiting the generality of the foregoing, INVESCO
(NY) shall not, in connection with INVESCO (NY)'s duties under this Agreement,
be under any duty or obligation to inquire into and shall not be liable for or
in respect of:

                    (1)  the validity or invalidity or authority or lack of
               authority of any Oral or Written Instruction, notice or other
               instrument which conforms 


                                        - 5 -
<PAGE>

               to the applicable requirements of this Agreement, if any and that
               INVESCO (NY) reasonably believes to be genuine; and

                    (2)  delays or errors or loss of data occurring by reason of
               circumstances beyond INVESCO (NY)'s control including, without
               limitation, acts of civil or military authorities, national
               emergencies, labor difficulties, fire, mechanical breakdown,
               denial of access, earthquake, flood or catastrophe, acts of God,
               insurrection, war, riots, or failure of the mails,
               transportation, communication or power supply.

Notwithstanding any other provisions of this Agreement, the following provisions
shall apply with respect to INVESCO (NY)'s computation of a Fund's net asset
value:  INVESCO (NY) shall be held to the exercise of reasonable care in
computing and determining net asset value as provided in Section 4(a), above,
but shall not be held accountable or liable for any losses, damages or expenses
of a Fund or any Shareholder or former Shareholder may incur arising from or
based upon errors or delays in the determination of such net asset value unless
such error or delay was due to INVESCO (NY)'s negligence or willful misfeasance
in the computation and determination of such net asset value.  The parties
hereto acknowledge, however, that INVESCO (NY) causing an error or delay in the
determination of net asset value may, but does not in an of itself, constitute
negligence or willful misfeasance.  In no event shall INVESCO (NY) be liable or
responsible to the Company or a Fund or any other party for any error or delay
which continued or was undetected after the date of an audit of the Company or
any Fund performed by the certified public accountants employed by the Company
if, in the exercise of reasonable care in accordance with generally accepted
accounting principles, such accountants should have become aware of such error
or delay in the course of performing such audit.  INVESCO (NY)'s liability for
any such negligence or willful misfeasance which results in an error in
determination of such  net asset value be limited to the direct out-of-pocket
loss a Fund and/or any Shareholder or former Shareholder shall actually incur.

          Without limiting the generality of the foregoing, INVESCO (NY) shall
not be held accountable or liable to a Fund a Shareholder or former Shareholder
or any other person for any delays or losses, damages or expenses any of them
may suffer or incur resulting from (1) INVESCO (NY)'s failure to receive timely
and suitable notification concerning quotations, corporate actions or similar
matters relating to or affecting portfolio securities of a Fund or (2) any
errors in the computation of a net asset value based upon or arising out of
quotations or information as to corporate actions if received by INVESCO (NY)
from a source that INVESCO (NY) was authorized to rely upon. Nevertheless,
INVESCO (NY) will use its best judgment in determining whether to verify through
other sources any information that it has received as to quotations or corporate
actions if INVESCO (NY) has reason to believe that any such information is
incorrect.

          SECTION 10.  RECEIPT OF ADVICE.  If INVESCO (NY) is in doubt as to any
action to be taken or omitted by it, INVESCO (NY) may request, and shall be
entitled to rely upon, directions and advice from the Company, including Oral or
Written Instructions where 


                                        - 6 -
<PAGE>

appropriate, or from counsel of its own choosing (who may also be counsel for
the Company or any Fund), with respect to any question of law.  In case of
conflict between directions, advice or Oral and Written Instructions received by
INVESCO (NY) pursuant to this Section, INVESCO (NY) shall be entitled to rely on
and follow the advice received from counsel as described above.  INVESCO (NY)
shall be protected in any action or in action that it takes in reliance on any
directions, advice or Oral or Written Instructions received pursuant to this
Section that INVESCO (NY), after the receipt of the same, in good faith believes
to be consistent with such directions, advice or Oral or Written Instructions,
as the case may be.  Notwithstanding the foregoing, nothing in this Section
shall be construed as imposing on INVESCO (NY) any obligation to seek such
directions, advice or Oral or Written Instruction, or to act in accordance with
them when received, unless the same is a condition to INVESCO (NY)'s properly
taking or omitting to take such action under the terms of this Agreement.

          SECTION 11.  INDEMNIFICATION OF INVESCO (NY).  The Company agrees to
indemnify and hold harmless INVESCO (NY) and its officers, directors, employees,

                       FUND ACCOUNTING AND PRICING AGENT FEES
                                          
       The Fund shall pay a Fee to INVESCO (NY) determined as a percentage of
the Fund's net assets. The annualized rate at which the fee is paid (the Fee
Rate) and the Fee shall be calculated as set forth below:

- -  An ASSET MULTIPLIER is determined by multiplying .0003 times the first $5
   billion in average net assets of the INVESCO (NY) Funds plus .0002 times the
   net assets over $5 billion.

- -  The FEE RATE is determined by dividing the Asset Multiplier by the net
   assets of the INVESCO (NY) Funds.

- -  The MONTHLY FEE is determined then by multiplying the average daily Fee Rate
   by the number of days in the month and by the Fund's average daily net
   assets then dividing by 365/or 366

Example:  For Fund X having $100 million in average net assets during December
1997, in which the INVESCO (NY) Funds have average net assets of $8 billion:

   Asset Multiplier = (.0003) ($5 billion) + (.0002) ($3 billion) = $2.1 million

   Fee Rate = $2.1 Million = .0002625
              ------------
               $8 billion

      Monthly Fee = (  31  ) (.0002625) ($100 million) = $2,229.45
                     ------
                    ( 365  )

8.   CONVERSION OF CLASS B SHARES.

     a.   SHARES RECEIVED UPON REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS -
          Shares purchased through the reinvestment of dividends and
          distributions paid on Shares subject to conversion shall be treated as
          if held in a separate sub-account. Each time any Shares in a
          shareholder's account (other than Shares held in the sub-account)
          convert to Class A Shares, a proportionate number of Shares held in
          the sub-account shall also convert to Class A Shares.

     b.   CONVERSIONS ON BASIS OF RELATIVE NET ASSET VALUE - All conversions
          shall be effected on the basis of the relative net asset values of the
          two Classes without the imposition of any sales load or other charge.

     c.   AMENDMENTS TO PLAN OF DISTRIBUTION FOR CLASS A SHARES - If any
          amendment is proposed to the Plan of Distribution under which Service
          Fees and Distribution Fees are paid with respect to Class A Shares of
          a Fund that would increase materially the amount to be borne by those
          Class A Shares, then no Class B Shares shall convert into Class A
          Shares of that Fund until the holders of Class B Shares of that Fund
          have also approved the proposed amendment. If the holders of such
          Class B Shares do not approve the proposed amendment, the Directors of
          the Fund and the Distributor shall take such action as is necessary to
          ensure that the Class voting against the amendment shall convert into
          another Class identical in all material respects to Class A Shares of
          the Fund as constituted prior to the amendment.

9.   This Plan shall not take effect until a majority of the Directors of a
     Fund, including a majority of the Directors who are not interested persons
     of the Fund, shall find that the Plan, as proposed and including the
     expense allocations, is in the best interests of each Class individually
     and the Fund as a whole.

10.  This Plan may not be amended to materially change the provisions of this
     Plan unless such amendment is approved in the manner specified in Section 9
     above.
