                               years following the end of the calendar month in which a purchase
                               was made. Class B shares are subject to higher annual expenses
                               than Class A shares.
 
Shares Available Through:      Class A and Class B shares are available through broker/dealers,
                               banks and other financial service entities ("Financial

- ------------------
(1)  THESE TABLES ARE 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. THE "HYPOTHETICAL EXAM-
     PLE" SET FORTH ABOVE 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 above 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.
(2)  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.
(3)  Expenses are based on the Fund's fiscal year ended December 31, 1997.
     "Other expenses" include custody, transfer agent, legal, audit and other
     expenses. AIM has undertaken to limit the Fund's expenses (exclusive of
     brokerage commissions, taxes, interest and extraordinary expenses) to the
     annual rate of 1.00% and 1.75% of the average daily net assets of the
     Fund's Class A and Class B shares, respectively. See "Management" herein
     and the Statement of Additional Information for more information. Without
     reimbursements or waivers, "Investment Management and Administration Fees,"
     "12b-1 distribution and service fees," "Other Expenses" and "Total Fund
     Operating Expenses" would have been 0.50%, 0.25%, 0.53%, and 1.28%,
     respectively, for Class A shares and 0.50%, 1.00%, 0.53%, and 2.03%,
     respectively, for Class B shares. The Fund also offers Advisor Class
     shares, which are not subject to 12b-1 distribution and service fees, to
     certain categories of investors. See "How to Invest."
(4)  Assumes deduction of the applicable contingent deferred sales charge.
+    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.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
The Fund's investment objective is to seek maximum current income consistent
with liquidity and conservation of capital. The Fund seeks this objective by
investing in high quality, U.S. dollar-denominated money market instruments,
i.e., debt obligations with remaining maturities of 13 months or less.
 
The Fund seeks to maintain a net asset value of $1.00 per share. To do so, the
Fund uses the amortized cost method of valuing its securities pursuant to Rule
2a-7 under the Investment Company Act of 1940, as amended (the "1940 Act"),
certain requirements of which are summarized below.
 
In accordance with Rule 2a-7, the Fund will (i) maintain a dollar-weighted
average portfolio maturity of 90 days or less and (ii) purchase only instruments
having remaining maturities of 13 months or less.
 
   
The Fund will invest only in high quality, U.S. dollar-denominated money market
instruments determined by the Sub-adviser to present minimal credit risks in
accordance with procedures established by the Company's Board of Trustees (the
"Board"). To be considered high quality, a security must be rated in accordance
with applicable rules in one of the two highest rating categories for short-term
securities by at least two nationally recognized statistical rating
organizations ("NRSROs") (or one, if only one such NRSRO has rated the security)
or, if the issuer has no applicable short-term rating, determined by the
Sub-adviser to be of equivalent credit quality.
    
 
   
High quality securities are divided into "first tier" and "second tier"
securities. The Fund will invest only in first tier securities. First tier
securities have received the highest rating for short-term debt from at least
two NRSROs, i.e., rated not lower than 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 one, if only one such NRSRO has rated the security) or, if
unrated, are determined to be of equivalent quality as described above. If a
security has been assigned different ratings by different NRSROs, at least two
NRSROs must have assigned the higher rating in order for the Sub-adviser to
determine the security's eligibility for purchase by the Fund.
    
 
The rating criteria of S&P and Moody's, two NRSROs currently rating instruments
of the type the Fund may purchase, are more fully described in "Description of
Debt Ratings" in the Statement of Additional Information.
 
PERMITTED INVESTMENTS. The Fund may invest in the following types of money
market instruments:
 
/ / OBLIGATIONS ISSUED OR GUARANTEED BY THE U.S. AND FOREIGN GOVERNMENTS, THEIR
    AGENCIES AND INSTRUMENTALITIES. These include: direct obligations of the
    U.S. Treasury, such as Treasury bills and notes; obligations backed by the
    full faith and credit of the U.S. government, such as those issued by the
    Government National Mortgage Association; obligations supported primarily or
    solely by the creditworthiness of the issuer, such as securities of Fannie
    Mae (also known as the Federal National Mortgage Association), Freddie Mac
    (also known as the Federal Home Loan Mortgage Corporation) and the Tennessee
    Valley Authority; and similar U.S.-dollar denominated instruments of foreign
    governments, their agencies, authorities and instrumentalities.
 
/ / OBLIGATIONS OF U.S. AND NON-U.S. BANKS, including certificates of deposit,
    bankers' acceptances and similar instruments, when such banks have total
    assets at the time of purchase equal to at least $1 billion.
 
/ / INTEREST-BEARING DEPOSITS IN U.S. COMMERCIAL AND SAVINGS BANKS having total
    assets of $1 billion or less, in principal amounts at each such bank not
    greater than are insured by an agency of the U.S. government, provided that
    the aggregate amount of such deposits (including interest earned) does not
    exceed 5% of the Fund's assets.
 
   
/ / COMMERCIAL PAPER AND OTHER SHORT-TERM DEBT OBLIGATIONS OF U.S. AND FOREIGN
    COMPANIES, rated at least A-1 by S&P or Prime-1 by Moody's or, if not rated,
    determined by the Sub-adviser to be of equivalent quality, provided that any
    outstanding intermediate- or long-term debt of the issuer is rated at least
    AA by S&P or Aa by Moody's. These instruments may include corporate bonds
    and notes
    
 
                               Prospectus Page 8
<PAGE>
                             GT GLOBAL DOLLAR FUND
    (corporate obligations that mature, or that may be redeemed, in one year or
    less). These corporate obligations include variable rate master notes, which
    are redeemable upon notice and permit investment of fluctuating amounts at
    varying rates of interest pursuant to direct arrangements with the issuer of
    the instrument.
 
   
/ / REPURCHASE AGREEMENTS SECURED BY ANY OF THE FOREGOING. A repurchase
    agreement is a transaction in which the 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 the Fund
    if the other party to the repurchase agreement becomes bankrupt, the Fund
    will enter into repurchase agreements only with banks and dealers believed
    by the Sub-adviser to present minimal credit risks in accordance with
    guidelines approved by the Board. The Sub-adviser will review and monitor
    the creditworthiness of such institutions under the Board's general
    supervision. The Fund will not enter into repurchase agreements with
    maturities of more than seven days if, as a result, more than 10% of the
    value of its net assets would be invested in such repurchase agreements and
    other illiquid securities.
    
 
   
INVESTMENT TECHNIQUES. In managing the Fund, the Sub-adviser may employ a number
of professional money management techniques, including varying the composition
of the Fund's investments and the average weighted maturity of the Fund's
portfolio within the limitations described above. Determinations to use such
techniques will be based on the Sub-adviser's identification and assessment of
the relative values of various money market instruments and the future of
interest rate patterns, economic conditions and shifts in fiscal and monetary
policy. The Sub-adviser also may seek to improve the Fund's yield by purchasing
or selling securities in order to take advantage of yield disparities that
regularly occur in the market. For example, frequently there are yield
disparities between different types of money market instruments, and market
conditions from time to time result in similar securities trading at different
prices.
    
 
RISKS AND OTHER CONSIDERATIONS. Investors should recognize that in periods of
declining interest rates, the Fund's yield will tend to be somewhat higher than
prevailing market rates; conversely, in periods of rising interest rates, the
Fund's yield will tend to be somewhat lower than those rates. Also, when
interest rates are falling, the net new money flowing into the Fund from the net
sale of its shares likely will be invested in instruments producing lower yields
than the balance of the Fund's portfolio, thereby reducing its yield. The
opposite generally will be true in periods of rising interest rates. The Fund is
designed to provide maximum current income consistent with the liquidity and
safety of principal afforded by investment in a portfolio of high quality money
market instruments; the Fund's yield may be lower than that produced by funds
investing in lower quality and/or longer-term securities.
 
Although the Fund may invest in instruments of non-U.S. issuers, all such
instruments will be denominated in U.S. dollars and will be first tier
securities. Obligations of non-U.S. issuers are subject to the same risks that
pertain to domestic issues, notably credit risk, market risk and liquidity risk.
Nonetheless, these instruments present risks that are different from those
presented by investment in instruments of U.S. issuers. Obligations of foreign
entities may be subject to certain sovereign risks, including adverse political
and economic developments in a foreign country, the extent and quality of
government regulation of financial markets and institutions, interest
limitations, currency controls, foreign withholding taxes, and expropriation or
nationalization of foreign issuers and their assets. There may be less publicly
available information about foreign issuers than about domestic issuers, and
foreign issuers may not be subject to the same accounting, auditing and
financial recordkeeping standards and requirements as are domestic issuers.
Accordingly, while the Fund's ability to invest in these instruments may provide
it with the potential to produce a higher yield than money market funds
investing solely in instruments of domestic issuers, the Fund presents greater
risk than such other funds.
 
VARIABLE AND FLOATING RATE SECURITIES. The Fund may purchase variable and
floating rate securities with remaining maturities in excess of 13 months. Such
securities must comply with conditions established by the SEC under which they
may be considered to have remaining maturities of 13 months or less. The yield
of these securities varies in relation to changes in specific money market rates
such as the prime rate. These changes are reflected in adjustments to the yields
of the
 
                               Prospectus Page 9
<PAGE>
                             GT GLOBAL DOLLAR FUND
   
variable and floating rate securities, and different securities may have
different adjustment rates. To the extent that the Fund invests in such variable
and floating rate securities, it is the Sub-adviser's view that the Fund may be
able to take advantage of the higher yield that is usually paid on longer-term
securities. The Sub-adviser further believes that the variable and floating
rates paid on such securities may substantially reduce the wide fluctuations in
market value caused by interest rate changes and other factors which are typical
of longer-term debt securities.
    
 
OTHER INFORMATION. The Fund may acquire participation interests in securities in
which it is permitted to invest. Participation interests are pro rata interests
in securities held by others. Pending investment of proceeds from new sales of
Fund shares or for temporary defensive purposes, the Fund may hold any portion
of its assets in cash. The Fund may borrow money from banks as a temporary
measure (a) for extraordinary or emergency purposes in amounts up to 5% of its
net assets (taken at market value) or (b) in amounts up to 33 1/3% of its net
assets in order to meet redemption requests. The Fund will not purchase
securities while borrowings remain outstanding. The Fund may invest no more than
5% of its total assets in the securities of a single issuer (other than
securities issued or guaranteed by the U.S. government, its agencies, or
instrumentalities).
 
The Fund's investment objective and policies with respect to borrowing as stated
above are fundamental and may not be changed without the approval of a majority
of its outstanding voting securities. A "majority of the Fund's outstanding
voting securities" means the lesser of (i) 67% of its shares represented at a
meeting at which more than 50% of the outstanding shares are represented, and
(ii) more than 50% of its outstanding shares. In addition, the Fund has adopted
certain investment limitations that also may not be changed without shareholder
approval. A description of these limitations is included in the Statement of
Additional Information. The Fund's other investment policies described herein
are not fundamental and may be changed by vote of the Board without shareholder
approval.
 
On December 29, 1992, the shareholders of the Fund approved modifications to the
Fund's investment policies and limitations that authorize the Board to effect a
change in the operating structure of the Fund, so that it may transfer all of
its investable assets to the Global Dollar Portfolio ("Portfolio"), an open-end
management investment company with substantially the same investment objective,
limitations and policies as the Fund. The Portfolio may serve as the investment
vehicle for different entities that have the same investment objective and
policies as the Fund. By investing in the Portfolio rather than maintaining its
own portfolio of securities, the Fund would expect to realize certain economies
of scale that would arise as additional investors invest their assets in the
Portfolio. There is no assurance that institutional investors will invest in the
Portfolio or that any of these expected benefits would actually be realized by
the Fund. Implementation of this new operating structure will only occur upon
approval of the Board.
 
   
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.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
GENERAL. The Fund is authorized to issue three classes of shares. Class A shares
are sold to investors with no sales charge, while Class B shares may be obtained
only through an exchange of Class B shares of other GT Global Mutual Funds,
except with respect to investors participating in the Portfolio Rebalancing
Program described below. The third class of shares of the Fund, the Advisor
Class, may be offered through a separate prospectus only to certain investors.
 
   
Class A shares of the Fund may be purchased through Financial Institutions, some
of which may charge the investor a transaction fee. Some of these Financial
Institutions (or their designees) may be authorized to accept purchase orders on
behalf of the Fund. All purchase orders will be executed at the public offering
price next determined after the purchase order is received. Orders received by
the Transfer Agent before the close of regular trading on the New York Stock
Exchange ("NYSE") (currently 4:00 p.m. Eastern Time, unless weather, equipment
failure or other factors contribute to an earlier closing time) on any Business
Day will be executed at the Fund's net asset value per share determined that
day. Orders received by authorized institutions (or their designees) before the
close of regular trading on the NYSE on a Business Day will be deemed to have
been received by the 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. A "Business Day" is any day Monday through Friday on
which the NYSE is open for business. Financial Institutions are responsible for
forwarding the investor's order to the Transfer Agent so that it will be
received prior to the required time.
    
 
   
The minimum initial investment is $500 ($100 for IRAs and $25 for custodial
accounts under Section 403(b)(7) of the Internal Revenue Code of 1986, as
amended (the "Code"), and other tax-qualified employer-sponsored retirement
accounts, if made under a systematic investment plan providing for monthly
payments of at least that amount). The minimum for additional purchases is $100
($25 for IRAs, Code Section 403(b)(7) custodial accounts and other tax-qualified
employer-sponsored retirement accounts, as mentioned above). Prior to receipt of
Federal Funds, an investor's money will not be invested. "Federal Funds" are
monies held on deposit at a Federal Reserve Bank that are available for the
Fund's immediate use. Purchases by check or negotiable bank draft normally take
two business days to be converted into Federal Funds. Shares begin accruing
income dividends on the day following the date of purchase. THE FUND AND AIM
DISTRIBUTORS RESERVE THE RIGHT TO REJECT ANY PURCHASE ORDER AND TO SUSPEND THE
OFFERING OF SHARES FOR A PERIOD OF TIME. In particular, the Fund and AIM
Distributors may reject purchase orders or exchanges by investors who appear to
follow, in the Sub-adviser's judgment, a market-timing strategy or otherwise
engage in excessive trading. See "How to Make Exchanges -- Limitations on
Purchase Orders and Exchanges."
    
 
   
PURCHASES THROUGH THE TRANSFER AGENT. After an initial investment is made and a
shareholder account is established through a Financial Institution, at the
investor's option, subsequent purchases may be made directly through the
Transfer Agent. See "Shareholder Account Manual." Investors may also make an
initial investment in the Fund and establish a shareholder account directly
through GT Global by completing and signing an Account Application accompanying
this Prospectus. Investors should mail to the Transfer Agent the completed
Application together with a check to cover the purchase in accordance with the
instructions provided in the Shareholder Account Manual. Purchases will be
executed at the net asset value next determined after the Transfer Agent has
received the Account Application and check and Federal Funds become available to
the Fund. Subsequent investments do not need to be accompanied by an
application.
    
 
   
Investors also may purchase shares of the Fund by bank wire. Bank wire purchases
will be effected at the net asset value next determined after the bank wire is
received. A wire investment is considered received when the Transfer Agent is
notified that the bank wire has been credited to the Fund. The investor is
responsible for providing prior telephonic or facsimile notice to the Transfer
Agent
    
 
                               Prospectus Page 11
<PAGE>
                             GT GLOBAL DOLLAR FUND
that a bank wire is being sent. An investor's bank may charge a service fee for
wiring money to the Fund. The Transfer Agent currently does not charge a service
fee for facilitating wire purchases, but reserves the right to do so in the
future. Investors desiring to open an account by bank wire should call the
Transfer Agent at the appropriate toll-free number provided in the Shareholder
Account Manual to obtain an account number and detailed instructions.
 
CERTIFICATES. In the interest of economy and convenience, the Fund does not
issue physical certificates representing its shares. Shares of the Fund are
recorded on a register by the Transfer Agent, and shareholders have the same
rights of ownership as if certificates had been issued to them.
 
DIFFERENCES BETWEEN THE CLASSES. The primary differences between the classes of
the Fund's shares offered through this Prospectus lie in their ongoing expenses
and role as exchange vehicles for the corresponding classes of shares of the GT
Global Mutual Funds, as summarized below. Class A and Class B shares of the Fund
represent interests in the same Fund and have the same rights, except that each
class bears the separate expenses of its 12b-1 distribution plan and has
exclusive voting rights with respect to such plan, each class can experience
other minor expense differences and, in addition to different sales charges,
each class has a separate exchange privilege. Class A shares are available for
purchase directly by investors. Except for investors participating in the
Portfolio Rebalancing Program, Class B shares may be purchased only through an
exchange of Class B shares of other GT Global Mutual Funds.
 
Dividends paid by the Fund with respect to Class A and Class B shares are
calculated in the same manner and at the same time. The per share dividends on
Class B shares will be lower than the per share dividends on Class A shares as a
result of the higher 12b-1 service and distribution fees applicable to Class B
shares.
 
The decision as to which class of shares is more beneficial to an investor
depends on the amount invested, the intended length of time the investment is
held and the investor's personal situation. Consult your financial adviser.
 
   
[ADVISOR CLASS SHARES. Advisor Class shares are offered through a separate
prospectus to [(a) trustees or 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 the program an annual fee of at least
 .50% of the assets in the account; (d) accounts advised by one of the companies
composing or affiliated with AMVESCAP PLC; and (e) any of those companies.]
    
 
   
AUTOMATIC INVESTMENT PLAN. Investors may purchase Class A shares of the Fund
through the GT Global Automatic Investment Plan. Under this Plan, an amount
specified by the shareholder of $100 or more (or $25 or more for IRAs, Code
Section 403(b)(7) custodial accounts and other tax-qualified employer-sponsored
retirement accounts) on a monthly or quarterly basis will be sent to the
Transfer Agent from the investor's bank for investment in the Fund. To
participate in the Automatic Investment Plan, investors should complete the
appropriate portion of the Supplemental Application provided at the end of this
Prospectus. Investors should contact their Financial Institution or AIM
Distributors for more information.
    
 
PORTFOLIO REBALANCING PROGRAM. The GT Global Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of GT Global Mutual Funds. The Program automatically
rebalances holdings of GT Global Mutual 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, GT Global Mutual Funds ("Personal Portfolio") is to
be rebalanced on a monthly, quarterly, semiannual, or annual basis.
 
Rebalancing under the Program will be effected through the exchange of shares of
one or more GT Global Mutual Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other GT Global Mutual Funds in the
shareholder's Personal Portfolio. See "How to Make Exchanges." If shares of the
GT Global Mutual Fund(s) in a shareholder's Personal Portfolio have appreciated
during a rebalancing period, the Program will result in shares of GT Global
Mutual Fund(s) that have appreciated most during the period being exchanged for
shares of GT Global
 
                               Prospectus Page 12
<PAGE>
                             GT GLOBAL DOLLAR FUND
Mutual 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 and Federal Income Taxation."
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 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 a Fund's shares. Exchanges made
under the Program are not subject to the four free exchanges per year
limitation. The 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 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 Financial Institutions
may charge a fee for establishing accounts relating to the Program. Investors
should contact their Financial Institution or AIM Distributors for more
information.

                             HOW TO MAKE EXCHANGES
 
- --------------------------------------------------------------------------------
 
   
Fund shares may be exchanged for shares of the same class of any other GT Global
Mutual Fund, based on their respective net asset values, provided that the
registration remains identical. The exchange of Class B shares will not be
subject to a contingent deferred sales charge. See "Dividends and Federal Income
Taxation." Class A shares of the Fund also may be exchanged for Class A shares
of funds of The AIM Family of Funds and for AIM Cash Reserve Shares of the AIM
Money Market Fund. However, purchases of Class A shares of GT Global Mutual
Funds of $1,000,000 or more that are subject to a contingent deferred sales
charge may not be exchanged for Class A shares of AIM Limited Maturity Treasury
Fund, AIM Tax-Free Intermediate Fund, or AIM Tax-Exempt Cash Fund. Exchanges
into The AIM Family of Funds will be based on their respective net asset values,
provided that the registration remains identical. For Class A shares, a sales
load will apply to exchanges from the Fund into another GT Global Mutual Fund or
a fund of The AIM Family of Funds; however, no sales load will be charged if the
exchanged shares were acquired as a result of a previous exchange from another
GT Global Mutual Fund.
    
 
   
EXCHANGES OF CLASS B SHARES. Although currently no exchanges are permitted
between the Fund and funds of The AIM Family of Funds with respect to Class B
shares, the Board of Trustees anticipates that such exchanges will be offered on
or about October 1, 1998.
    
 
   
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends, Other
Distributions and Federal Income Taxation." The GT Global Mutual Funds and The

If an investor does not surrender all of his or her shares in an exchange, the
remaining balance in the investor's account after the exchange must be at least
$500. Exchange requests received in good order by the Transfer Agent before the
close of regular trading on the NYSE on any Business Day will be processed at
the net asset value determined that day. The terms of the exchange offer may be
modified at any time, on 60 days' prior written notice.
 
An investor interested in making an exchange should contact his or her Financial
Institution or the Transfer Agent to request the prospectus of the
 
                               Prospectus Page 14
<PAGE>
                             GT GLOBAL DOLLAR FUND
other GT Global Mutual Fund(s) being considered. Certain Financial Institutions
may charge a fee for handling exchanges.
 
   
EXCHANGES BY TELEPHONE. A shareholder may give exchange information to the
shareholder's Financial Institution or to the Transfer Agent by telephone at the
appropriate toll-free number provided in the Shareholder Account Manual.
Shareholders automatically have telephone privileges to authorize exchanges. The
Fund, AIM Distributors and the Transfer Agent will not be liable for any loss or
damage for acting in good faith upon instructions received by telephone and
reasonably believed to be genuine. The Fund employs reasonable procedures to
confirm that instructions communicated by telephone are genuine prior to acting
upon instructions received by telephone, including requiring some form of
personal identification, providing written confirmation of such transactions,
and/or tape recording of telephone instructions.
    
 
EXCHANGES BY MAIL. Exchange orders should be sent by mail to the shareholder's
Financial Institution or to the Transfer Agent at the address set forth in the
Shareholder Account Manual.
 
   
LIMITATIONS ON PURCHASE ORDERS AND EXCHANGES. The GT Global Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market-timing
investment strategies and excessive trading can have on efficient portfolio
management, each GT Global Mutual Fund and AIM Distributors reserve the right to
refuse purchase orders and exchanges by any person or group, if, in the
Sub-adviser's judgment, such person or group was following a market-timing
strategy or was otherwise engaging in excessive trading.
    
 
   
In addition, each GT Global Mutual Fund and AIM Distributors reserve the right
to refuse purchase orders and exchanges by any person or group if, in the
Sub-adviser's judgment, the Fund would not be able to invest the money
effectively in accordance with that Fund's investment objective and policies or
would otherwise potentially be adversely affected. Although a GT Global Mutual
Fund will attempt to give investors prior notice whenever it is reasonably able
to do so, it may impose the above restrictions at any time.
    
 
   
Finally, as described above, the Fund and AIM Distributors reserve the right to
reject any purchase order.

                              HOW TO REDEEM SHARES
 
- --------------------------------------------------------------------------------
 
   
As described below, Class A shares may be redeemed without charge at net asset
value. Class B shares may be redeemed at their net asset value (subject to any
applicable contingent deferred sales charge ("CDSC")). A shareholder's holding
period of Class B shares of the Fund, as well as his or her holding period of
Class B shares of any other GT Global Mutual Fund exchanged to purchase Class B
shares of the Fund, will be credited for purposes of measuring the CDSC. Except
for investors participating in the Program, Class B shares may be obtained only
through an exchange of Class B shares of other GT Global Mutual Funds.
Shareholders with accounts at broker/dealers that sell shares of the Fund may
redeem shares through such broker/dealers. If the shares are held in the
broker/dealer's "street name," the redemption must be made through the
broker/dealer. Other shareholders may redeem shares through the Transfer Agent.
If a redeeming shareholder owns both Class A and Class B shares, Class A shares
will be redeemed first unless the shareholder specifically requests otherwise.
Shareholders also may redeem shares by writing checks against their Fund
accounts.
    
 
   
Class B shares may be redeemed on any business day at the net asset value per
share next determined following receipt of the redemption order, 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.

Sixth......................              1%
Seventh and Following......             None
</TABLE>
    
 
   
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 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.
    
 
For example, assume an investor purchased 100 Class B shares of another GT
Global Mutual Fund at $10 per share for a cost of $1,000. Subsequently, the
shareholder acquired 15 additional shares of that Fund through dividend
reinvestment. The investor then decides to exchange his or her shares of the
other GT Global Mutual Fund for Class B shares of the Fund. At the time of
exchange, the original Fund's shares had a net asset value of $11 per share, for
a total value of $1,265. Accordingly, the investor acquires 1,265 shares of the
Fund. The shareholder then acquires 50 additional shares of the Fund through
dividend reinvestment. Subsequently, in the third year after the original
purchase, the investor decides to redeem $500 of his or her investment. The CDSC
would not be applied to the value of any of the reinvested shares. Therefore,
$185 of the $500 redemption proceeds ($500 minus $315) would be charged at a
rate of 3% (the applicable rate in the third year after purchase) for a total
contingent deferred sales charge of $5.55.
 
   
Class B shares that are acquired pursuant to the exchange privilege during a
tender offer by GT Global Floating Rate Fund, Inc. ("Floating Rate Fund") will
be subject, in lieu of the CDSC described above, to a CDSC equivalent to the
early withdrawal charge on the common stock of the Floating Rate Fund. The
purchase of Class B shares of the Fund will be deemed to have occurred at the
time of the initial purchase of the Floating Rate Fund's common stock.
    
 
   
CONTINGENT DEFERRED SALES CHARGE WAIVERS. Contingent deferred sales charges on
Class B shares will be waived on redemptions (1) following the
    
 
                               Prospectus Page 16

                             GT GLOBAL DOLLAR FUND
   
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
individual retirement accounts, 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 shares at the time the shareholder elects to participate
in the Systematic Withdrawal Plan, (4) effected pursuant to the right of a GT
Global Mutual 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 this Prospectus of such GT Global Mutual Fund, and (5)
effected by AIM of its investment in Class B shares.
    
 
   
Waiver category (1) above applies only to redemptions of Class B 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 GT Global Mutual 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 shares of one or more GT Global Mutual 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 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 "Information Relating
to Sales and Redemptions -- Sales Charge Waivers for Shares Purchased Prior to
June 1, 1998."
    
 
   
CONVERSION OF CLASS B SHARES. Class B shares automatically will convert into
Class A shares of the same Fund (together with a pro rata portion of all Class B
shares acquired through the reinvestment of dividends and distributions) eight
years from the end of the calendar month in which the purchase of Class B shares
was made. Following such conversion of Class B shares, investors will be
relieved of the higher Rule 12b-1 Plan payments associated with Class B shares.
    
 
REDEMPTIONS THROUGH THE TRANSFER AGENT. Redemption requests may be transmitted
to the Transfer Agent by telephone or by mail, in accordance with the
instructions provided in the Shareholder Account Manual. Redemptions will be
effected at the net asset value (less any applicable contingent deferred sales
charge for Class B shares) next determined after the Transfer Agent has received
the request or after an Authorized Institution has received the request,
provided that the request is transmitted to the Transfer Agent prior to the time
set for receipt of such redemption requests. Redemptions will only be effected
if the request is received in good order and accompanied by any required
supporting documentation. Redemption requests will not require a signature
guarantee if the redemption proceeds are to be sent either: (i) to the redeeming
shareholder at the shareholder's address of record as maintained by the Transfer
Agent, provided the shareholder's address of record has not been changed in the
preceding fifteen days; or (ii) directly to a pre-designated bank, savings and
loan or credit union account ("Pre-Designated Account"). ALL OTHER REDEMPTION
REQUESTS MUST BE ACCOMPANIED BY A SIGNATURE GUARANTEE OF THE REDEEMING
SHAREHOLDER'S SIGNATURE. A signature guarantee can be obtained from any bank,
U.S. trust company, a member firm of a U.S. stock exchange or a foreign branch
of any of the foregoing or other eligible guarantor institution. A notary public
is not an acceptable guarantor. A shareholder with questions concerning the
Fund's signature guarantee requirement should contact the Transfer Agent.
 
Shareholders may qualify to have redemption proceeds sent to a Pre-Designated
Account by completing the appropriate section of the Account Application at the
end of this Prospectus. Shareholders with Pre-Designated Accounts should
 
                               Prospectus Page 17
<PAGE>
                             GT GLOBAL DOLLAR FUND
request that redemption proceeds be sent either by bank wire or by check. The
minimum redemption amount for a bank wire is $500. Shareholders requesting a
bank wire should allow two business days from the time the redemption request is
effected for the proceeds to be deposited in the shareholder's Pre-Designated
Account. See "How to Redeem Shares -- Other Important Redemption Information."
Shareholders may change their Pre-Designated Accounts only by a letter of
instruction to the Transfer Agent containing all account signatures, each of
which must be guaranteed. The Transfer Agent currently does not charge a bank
wire service fee for each wire redemption sent but reserves the right to do so
in the future. The shareholder's bank may charge a bank wire service fee.
 
REDEMPTIONS BY TELEPHONE. Redemption requests may be made by telephone by
calling the Transfer Agent at the appropriate toll-free number provided in the
Shareholder Account Manual. REDEMPTION REQUESTS MAY NOT BE MADE BY TELEPHONE FOR
FIFTEEN DAYS FOLLOWING ANY CHANGE OF THE SHAREHOLDER'S ADDRESS OF RECORD.
 
   
Shareholders automatically have telephone privileges to authorize redemptions.
The Fund, AIM Distributors and the Transfer Agent will not be liable for any
loss or damage for acting in good faith upon instructions received by telephone
and reasonably believed to be genuine. The Fund employs reasonable procedures to
confirm that instructions communicated by telephone are genuine prior to acting
upon instructions received by telephone, including requiring some form of
personal identification, providing written confirmation of such transactions,
and/or tape recording of telephone instructions.
    
 
REDEMPTIONS BY MAIL. Redemption requests should be mailed directly to the
Transfer Agent at the appropriate address provided in the Shareholder Account
Manual. As discussed above, requests for payment of redemption proceeds to a
party other than the shareholder of record and/or requests that redemption
proceeds be mailed to an address other than the shareholder's address of record
require a signature guarantee. In addition, if the shareholder's address of
record has been changed within the preceding fifteen days, a signature guarantee
is required.
 
CHECKWRITING. Shareholders may redeem Class A shares by writing checks, a supply
of which may be obtained through the Transfer Agent, against their Fund
accounts. The minimum check amount is $300. When the check is presented to the
Transfer Agent for payment, it will cause the Fund to redeem a sufficient number
of Class A shares to cover the amount of the check. This procedure enables the
shareholder to continue receiving dividends on those shares until the check is
presented to the Transfer Agent for payment. Cancelled checks are not returned;
however, shareholders may obtain photocopies of their cancelled checks upon
request. If a Class A shareholder does not own sufficient Class A shares to
cover a check, the check will be returned to the payee marked "not sufficient
funds." Checks written in amounts less than $300 also will be returned. The Fund
and the Transfer Agent reserve the right to terminate or modify the checkwriting
service at any time or to impose a service charge in connection therewith.
 
Because the aggregate amount of Class A shares owned by a shareholder is likely
to change each day, shareholders should not attempt to redeem all Class A shares
held in their accounts by using the check redemption procedure. Charges may be
imposed for specially imprinted checks, business checks, copies of cancelled
checks, stop payment orders, checks returned because of "not sufficient funds"
and checks returned because they are written for less than $300; these charges
will be paid by redeeming automatically an appropriate number of Class A shares.
 
Class A shareholders who are interested in checkwriting should obtain the
necessary forms by calling the Transfer Agent at the number provided in the
Shareholder Account Manual. Checkwriting generally is not available to persons
who hold Class A shares in tax-deferred retirement plan accounts.
 
Checkwriting is not available to redeem Class B shares.
 
SYSTEMATIC WITHDRAWAL PLAN. Shareholders owning shares with a value of $10,000
or more may participate in the GT Global Systematic Withdrawal Plan. A
participating shareholder will receive monthly, quarterly or annual redemptions
of Fund shares with respect to either Class A or Class B shares. No CDSC will be
imposed on redemptions made under the Systematic Withdrawal Plan. The minimum
withdrawal amount is $100. The amount or percentage a participating shareholder
specifies to be redeemed may not, on an annualized basis, exceed 12% of the
value of the account, as of the time the shareholder elects to participate in
the Systematic Withdrawal Plan. To participate in

<PAGE>
                             GT GLOBAL DOLLAR FUND
the Systematic Withdrawal Plan, investors should complete the appropriate
portion of the Supplemental Application provided at the end of this Prospectus.
Investors should contact their Financial Institution or the Transfer Agent for
more information. Systematic withdrawal plans offered by Financial Institutions
may have different features. Accordingly, shareholders should contact their
Financial Institution for more details.
 
OTHER IMPORTANT REDEMPTION INFORMATION. A request for redemption will not be
processed until all of the necessary documentation has been received in good
order. A shareholder in doubt about what documents are required should contact
his or her Financial Institution or the Transfer Agent.
 
   
Except in extraordinary circumstances and as permitted under the 1940 Act,
payment for shares redeemed by telephone or by mail will be made promptly after
receipt of a redemption request, if in good order, but not later than seven days
after the date the request is executed. Requests for redemption which are
subject to any special conditions or which specify a future or past effective
date cannot be accepted.
    
 
If the Transfer Agent is requested to redeem shares for which the Fund has not
yet received good payment, the Fund may delay payment of redemption proceeds
until the Transfer Agent has assured itself that good payment has been collected
for the purchase of the shares. In the case of purchases by check, it can take
up to 10 business days to confirm that the check has cleared and good payment
has been received. Redemption proceeds will not be delayed when shares have been
paid for by wire or when the investor's account holds a sufficient number of
shares for which funds already have been collected.
 
The Fund may redeem the shares of any shareholder whose account is reduced to
less than $500 in net asset value through redemptions or other action by the
shareholder. Written notice will be given to the shareholder at least 60 days
prior to the date fixed for such redemption, during which time the shareholder
may increase his or her holdings to an aggregate amount of $500 or more (with a
minimum purchase of $100 or more).

                         CALCULATION OF NET ASSET VALUE
 
- --------------------------------------------------------------------------------
 
The Fund intends to use its best efforts to maintain its net asset value at
$1.00 per share. There can be no assurance, however, that it will be able to do
so. The value of each share of the Fund is computed by dividing its net assets
by the number of its outstanding shares. "Net assets" equal the value of the
Fund's investments and other assets less its liabilities. The Fund calculates
its net asset value as of the close of regular trading on the NYSE (currently
4:00 p.m. Eastern Time, unless weather, equipment failure or other factors
contribute to an earlier closing time) each Business Day. Net asset value is
determined separately for each class of the Fund's shares.
 
The Fund values its portfolio securities using the amortized cost method of
valuation, pursuant to which the market value of an instrument is approximated
by amortizing the difference between the acquisition cost and value at maturity
of the instrument on a straight-line basis over its remaining life. All cash,
receivables and current payables are carried at their face value. Other assets,
if any, are valued at fair value as determined in good faith by or under the
direction of the Board.

                                 DIVIDENDS AND
                            FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS. Dividends are declared daily and paid monthly from the Fund's net
investment income and any realized net short-term capital gain (the excess of
short-term capital gains over short-term capital losses). The Fund's net
investment income includes accrued interest and earned discount (including both
original issue and market discounts), less amortization of premium and
applicable expenses. Fund shares begin to earn dividends on the day following
the day on which Federal Funds become available. Dividends paid by the Fund with
respect to all classes of its shares are calculated in the same manner and at
the same time. The per share dividends on Class B shares will be lower than the
per share dividends on Class A shares as a result of the higher 12b-1 service
and distribution fees applicable to the Class B shares; the per share dividends
on both such classes of shares will be lower than the per share dividends on the
Advisor Class shares as a result of the absence of any 12b-1 service and
distribution fees applicable to Advisor Class shares.
 
Dividends are automatically reinvested in Fund shares of the distributing class
unless the investor has elected to receive them in cash. Cash payments may be
elected on the Account Application located at the end of this Prospectus or
through the investor's broker/dealer. Reinvestments in the corresponding class
of shares of another GT Global Mutual Fund may only be directed to an account
with the identical shareholder registration and account number. An election to
receive dividends in additional shares or in cash may be changed at any time,
but, to be effective for a particular dividend, the investor or the investor's
broker/dealer must notify the Transfer Agent at least fifteen Business Days
prior to the payment date. Shares earn dividends on the day of redemption. THE
FEDERAL INCOME TAX STATUS OF DIVIDENDS IS THE SAME WHETHER THEY ARE RECEIVED IN
CASH OR REINVESTED IN ADDITIONAL SHARES.
 
The Fund does not expect to realize long-term capital gain and thus does not
anticipate payment of any capital gain distributions.
 
TAXES. The Fund intends to continue to qualify for treatment as a regulated
investment company under the Code. In each taxable year that the Fund so
qualifies, the Fund (but not its shareholders) will be relieved of federal
income tax on that part of its investment company taxable income (consisting of
net investment income and any net short-term
 
                               Prospectus Page 21
<PAGE>
                             GT GLOBAL DOLLAR FUND
capital gain) that is distributed to its shareholders. Those distributions are
taxable to the Fund's shareholders as ordinary income to the extent of its
earnings and profits, whether they are received in cash or reinvested in
additional shares.
 
The Fund provides federal income tax information to its shareholders annually,
including information about dividends paid during the preceding year.
 
The Fund must withhold 31% of all dividends payable to any individuals and
certain other noncorporate shareholders who (1) have not furnished to the Fund a
correct taxpayer identification number or a properly completed claim for
exemption on Form W-8 or W-9 or (2) otherwise are subject to backup withholding.
 
Taxpayer identification numbers may be furnished on the Account Application
provided at the end of this Prospectus. Fund accounts opened via a bank wire
purchase (see "How to Invest -- Purchases Through the Distributor") are
considered to have uncertified taxpayer identification numbers unless a
completed Form W-8 or W-9 or Account Application is received by the Transfer
Agent within seven days after the purchase. A shareholder should contact the
Transfer Agent if the shareholder is uncertain whether a proper taxpayer
identification number is on file with the Fund.
 
The foregoing is only a summary of some of the important federal income tax
considerations generally affecting the Fund and its shareholders. See "Dividends
and Taxes" in the Statement of Additional Information for a further discussion.
There may be other federal, state, local or foreign tax considerations
applicable to a particular investor. Prospective investors are therefore urged
to consult their tax advisers.

- --------------------------------------------------------------------------------
 
   
The Company's Board of Trustees has overall responsibility for the operation of
the Fund. The Company's Board of Trustees has approved all significant
agreements between the Company on the one side and persons or companies
furnishing services to the Fund on the other, including the investment advisory
and administrative services agreement with AIM, the investment sub-advisory and
sub-administration agreement with the Sub-adviser, the agreements with AIM
Distributors regarding distribution of the Fund's shares, the agreement with
State Street Bank and Trust Company as the custodian and the transfer agency
agreement with GT Global Investors Services, Inc., an affiliate of the
Sub-adviser. The day-to-day operations of the Fund are delegated to the officers
of the Company, subject always to the objective and policies of the Fund and to
the general supervision of the Company's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the 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
management and administration fees, computed daily and paid monthly, at the
annualized rate of 0.50% of the Fund's average daily net assets. 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 that paid by most mutual funds. AIM has undertaken to limit the
Fund's expenses (exclusive of brokerage commissions, interest, taxes and
extraordinary expenses) to the annual rate of 1.00% and 1.75% 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 at an annual rate derived by
applying 0.03% to the first $5 billion of assets of GT Global Funds and 0.02% to
the assets in excess of $5 billion and allocating the result according to the
Fund's average daily net assets.

AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment adviser to the Fund pursuant to a master investment advisory
agreement, dated as of               , 1998 (the "Advisory Agreement"). AIM was
organized in 1976 and, together with its subsidiaries, manages or advises [over
50] 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
agreement dated as of               , 1998. On May   , 1998, Liechtenstein
Global Trust AG ("GT"), the former indirect parent organization of the Sub-
adviser, consummated a purchase agreement with AMVESCAP PLC pursuant to which
AMVESCAP PLC acquired GT's Asset Management Division, which includes 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 GT Global Mutual
Funds, the Sub-adviser employs a team approach, taking advantage of its
investment resources around the world in seeking each Fund's investment
objective.

transactions will be effected.
    
 
   
DISTRIBUTION OF FUND SHARES. The Company has entered into master distribution
agreements relating
    
 
                               Prospectus Page 23
<PAGE>
                             GT GLOBAL DOLLAR FUND
   
to the Fund (the "Distribution Agreements"), dated               , 1998, with
AIM Distributors, a registered broker/dealer and a wholly owned subsidiary of
AIM. The address of AIM Distributors is P.O. Box 4739, Houston, Texas
77210-4739. The Distribution Agreements provide AIM Distributors with the
exclusive rights to distribute shares of the Fund directly and through
institutions with whom AIM Distributors has entered into selected dealer
agreements. Under the Distribution Agreements, AIM Distributors acts as the
distributor of Class A and Class B shares of the Fund.
    
 
   
AIM Distributors, at its own expense, may provide promotional incentives to
broker/dealers that sell shares of the Fund and/or shares of the other GT Global
Mutual Funds. In some instances additional compensation or promotional
incentives may be offered to broker/dealers that have sold or may sell
significant amounts of shares during specified periods of time. Such
compensation and incentives may include, but are not limited to, cash,
merchandise, trips and financial assistance to broker/dealers in connection with
preapproved conferences or seminars, sales or training programs for invited
sales personnel, payment for travel expenses (including meals and lodging)
incurred by sales personnel and members of their families or other invited
guests to various locations for such seminars or training programs, seminars for
the public, advertising and sales campaigns regarding one or more of the GT
Global Mutual Funds, and/ or other events sponsored by the broker/dealers. In
addition, AIM Distributors makes ongoing payments to brokerage firms, financial
institutions (including banks) and others that facilitate the administration and
servicing of shareholder accounts. 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 GT Global Mutual 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 GT Global
Mutual Fund's shares or the amount that any particular GT Global Mutual Fund
will receive as proceeds from such sales. Dealers may not use sales of the GT
Global Mutual 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 or 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 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 $l7 million of such purchases, plus 0.25%
of amounts in excess of $20 million of such purchases.
    
 
   
AIM Distributors may pay sales commissions to dealers and institutions who sell
Class B shares of the GT Global Mutual 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.
    
 
   
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 Company compensates AIM Distributors an aggregate amount of 0.50% of
the average daily net assets of Class A shares of the Fund.
    
 
                               Prospectus Page 24
<PAGE>
                             GT GLOBAL DOLLAR FUND
 
   
The Company also has 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
compensation to AIM Distributors at an annual rate of 1.00% of the average daily
net assets of Class B shares of the Fund.
    
 
   
The Class A Plan and the Class B Plan (together, the "Plans") are designed to
compensate AIM Distributors for certain promotional and other sales-related
costs, and to implement a dealer incentive program that provides for periodic
payments to selected dealers who furnish continuing personal shareholder
services to their customers who purchase and own Class A and Class B shares of
the Fund. Payments also can be directed by AIM Distributors to selected dealers
and financial institutions who have entered into service agreements with respect
to Class A and Class B shares of the Fund and who provide continuing personal
services to their customers who own Class A and Class B shares of the Fund. The
service fees payable to selected dealers and financial 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 or dealer's customers'
accounts that were purchased on or after a prescribed date set forth in the
Plans. Any amounts not payable as a service fee would constitute an asset-based
sales charge. Payments under the Plans are subject to any applicable limitations
imposed by the rules of the National Association of Securities Dealers, Inc.
    
 
   
The Plans do not obligate the Fund 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 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.
    
 
   
Under the Plans, AIM Distributors may in its discretion from time to time agree
to waive voluntarily all or any portion of its fee that has not been assigned or
transferred, 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.
For additional information concerning the operation of the Plans see the
Statement of Additional Information.
    
 
   
The Glass-Steagall Act and other applicable laws, among other things, generally
prohibit federally chartered or supervised banks from engaging in the business
of underwriting or distributing securities. Accordingly, AIM Distributors
intends to engage banks (if at all) only to perform administrative and
shareholder servicing functions. Banks and broker/dealer affiliates of banks
also may execute dealer agreements with GT Global for the purpose of selling
shares of the Fund. If a bank were prohibited from so acting, its shareholder
clients would be permitted to remain shareholders, and alternative means for
continuing the servicing of such shareholders would be sought. It is not
expected that shareholders would suffer any adverse financial consequences as a
result of any of these occurrences.

- --------------------------------------------------------------------------------
 
STATEMENTS AND REPORTS TO SHAREHOLDERS. Shareholders receive monthly statements
from the Transfer Agent detailing account transactions, such as an additional
investment, redemption or the payment of a dividend. Shortly after the end of
the Fund's fiscal year on December 31 and fiscal half-year on June 30 of each
year, shareholders receive an annual and semiannual report, respectively. These
reports list the securities held by the Fund and contain its financial
statements. In addition, the federal income status of dividends paid by the Fund
to its shareholders is reported after the end of each calendar year on Form
1099-DIV. Under certain circumstances, duplicate mailings of the foregoing
reports to the same household may be consolidated.
 
   
ORGANIZATION OF THE COMPANY. The Company was organized as a Delaware business
trust on May   , 1998. Prior to June 1, 1998,the Company operated under the name
of "G.T. Investment Portfolios, Inc.," a Maryland corporation organized in 1981.
From time to time, the Board may, at its discretion, establish additional funds,
each corresponding to a distinct investment portfolio and a distinct series of
the Company's shares.
    
 
   
Pursuant to the Company's Declaration of Trust, it 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 other distributions out of the income earned and gain realized on
the assets belonging to the Fund as may be declared at the discretion of the
Board of Trustees. Each share of the Fund is equal in earnings, assets and
voting privileges except that each class 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.
    
 
   
Fund shares are entitled to one vote per share (with proportional voting for
fractional shares) and are freely transferable. Shareholders have no preemptive
or conversion rights. Shares may be voted on the election of Trustees and on
other matters submitted to the vote of Fund shareholders. If one or more
additional funds were established, on any matter submitted to a vote of
shareholders, shares of each fund would be voted by that fund's shareholders
individually when the matter affected the specific interest of that fund only,
such as approval of that fund's investment advisory arrangements. In addition,
shares of the Fund may vote on matters affecting only that class. The shares of
all the Company's funds would 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. The Company would be required to hold a
shareholders' meeting in the event that at any time less than a majority of the
Trustees holding office had been elected by shareholders. Trustees shall
continue to hold office until their successors are elected and have qualified.
Shares of the Company's funds 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 upon a majority vote of the
shareholders qualified to vote in the election. Shareholders holding 10% of the
Company's outstanding voting securities may call a meeting of shareholders for
the purpose of voting upon the question of removal of any Trustee or for any
other purpose. The 1940 Act requires the Company to assist shareholders in
calling such a meeting.
    
 
SHAREHOLDER INQUIRIES. Shareholder inquiries may be made by calling the Fund at
(800) 223-2138 or by writing to the Fund at 50 California Street, 27th Floor,
San Francisco, CA 94111.
 
PERFORMANCE INFORMATION. From time to time the Fund may advertise its "yield"
and "effective yield" in advertisements or promotional materials ("Performance
Advertisements"). Both yield and effective yield are calculated separately for
Class A, Class B and Advisor Class shares of the Fund. Both yield figures are
based on historical earnings and are not intended to indicate future
performance. It can be expected that these yields will fluctuate substantially.
The "yield" of the Fund refers to the income generated by an investment in
 
                               Prospectus Page 26
<PAGE>
                             GT GLOBAL DOLLAR FUND
the Fund over a seven-day period (which period will be stated in the
advertisement). This income is then "annualized." That is, the amount of income
generated by the investment during that week is assumed to be generated each
week over a 52-week period and is shown as a percentage of the investment. The
"effective yield" is calculated similarly but, when annualized, the income
earned by an investment in the Fund is assumed to be reinvested. The "effective
yield" will be slightly higher than the "yield" because of the compounding
effect of this assumed reinvestment. The Fund's "yield" and "effective yield"
may reflect expenses after reimbursement pursuant to an undertaking that may be
in effect. See "Management." The Statement of Additional Information describes
the methods used to calculate the Fund's yield and effective yield.
 
In Performance Advertisements, the Fund may quote its average annual total
return ("Standardized Return"). Standardized Return is calculated separately for
each class of shares of the Fund. Standardized Return shows percentage rates
reflecting the average annual change in the value of an assumed investment in
the Fund at the end of one-, five-, and ten-year periods, reduced by the maximum
applicable sales charge imposed on sales of Fund shares. If a one-, five- and/or
ten-year period has not yet elapsed, data will be provided as to the end of a
shorter period corresponding to the life of the Fund. Standardized Return
assumes reinvestment of all dividends and capital gain distributions.
 
In addition, in order to more completely represent the Fund's performance or
more accurately compare such performance to other measures of investment return,
the Fund also may include in advertisements, sales literature and shareholder
reports other total return performance data ("Non-Standardized Return").
Non-Standardized Return reflects percentage rates of return encompassing all
elements of return; it assumes reinvestment of all dividends and capital gain
distributions. Non-Standardized Return may be quoted for the same or different
periods as those for which Standardized Return is quoted; it may consist of an
aggregate or average annual percentage rate of return, actual year-by-year rates
or any combination thereof. Non-Standardized Return may or may not take sales
charges into account; performance data calculated without taking the effect of
sales charges into account will be higher than data including the effect of such
charges.
 
The Fund's performance data reflects past performance and is not necessarily
indicative of future results. The Fund's investment results will vary from time

YEAR 2000 COMPLIANCE PROJECT. In providing services to the GT Global Mutual
Funds, AIM, AIM Distributors, the Transfer Agent and the Sub-adviser rely on
internal computer systems as well as external computer systems provided by third
parties. Some of these systems were not originally designed to distinguish
between the year 1900 and the year 2000. This inability, if not corrected, could
adversely affect the services AIM Distributors, the Transfer Agent and the
Sub-adviser and others provide the GT Global Mutual Funds and their
shareholders.
    
 
   
To address this important issue, AIM, AIM Distributors, the Transfer Agent and
the Sub-adviser have undertaken a comprehensive Year 2000 Compliance Project
(the "Project"). The Project consists of four phases: (i) inventorying every
software and hardware system in use at AIM, AIM Distributors, the Transfer Agent
and the Sub-adviser, as well as remote, third-party systems on which AIM, AIM
Distributors, the Transfer Agent and the Sub-adviser rely; (ii) identifying
those systems that may not function properly after December 31, 1999; (iii)
correcting or replacing those systems that have been so identified; and (iv)
testing the processing of GT Global Mutual Fund data in all systems. Phase (i)
has been completed; phase (ii) is substantially completed; phase (iii) has
commenced; and phase (iv) is expected to commence during the third quarter of
1998. The Project is scheduled to be completed by December 31, 1998. Following
completion of the Project, AIM, AIM Distributors and the Sub-adviser will ensure
that any systems subsequently acquired are year 2000 compliant.
    
 
   
TRANSFER AGENT. Shareholder servicing, reporting and general transfer agent
functions for the Fund are performed by GT Global Investor Services, Inc. The
Transfer Agent is an affiliate of the Sub-adviser and AIM and maintains offices
at California Plaza, 2121 North California Boulevard, Suite 450, Walnut Creek,
CA 94596.
    
 
CUSTODIAN. State Street Bank and Trust Company, 225 Franklin Street, Boston, MA
02110 is custodian of the Fund's assets.

(1) THESE TABLES ARE INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. THE "HYPOTHETICAL
    EXAMPLE" SET FORTH ABOVE 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 above 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.
    
 
   
(2) Expenses are based on the Fund's fiscal year ended December 31, 1997. "Other
    Expenses" include custody, transfer agency, legal, audit and other operating
    expenses. Effective January 1, 1998, AIM has undertaken to limit the Fund's
    expenses (exclusive of brokerage commissions, taxes, interest and
    extraordinary expenses) to the annual rate of 1.00% of the average daily net
    assets of the Fund's Advisor Class shares. See "Management" herein and the
    Statement of Additional Information for more information. Without
    reimbursements, "Investment management and administration fees," "Other
    Expenses" and "Total Fund Operating Expenses" would have been 0.50%, 0.53%
    and 1.03%, respectively, for the Fund. 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.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
The Fund's investment objective is to seek maximum current income consistent
with liquidity and conservation of capital. The Fund seeks this objective by
investing in high quality, U.S. dollar-denominated money market instruments,
i.e., debt obligations with remaining maturities of 13 months or less.
 
The Fund seeks to maintain a net asset value of $1.00 per share. To do so, the
Fund uses the amortized cost method of valuing its securities pursuant to Rule
2a-7 under the Investment Company Act of 1940, as amended (the "1940 Act"),
certain requirements of which are summarized below.
 
In accordance with Rule 2a-7, the Fund will (i) maintain a dollar-weighted
average portfolio maturity of 90 days or less and (ii) purchase only instruments
having remaining maturities of 13 months or less.
 
   
The Fund will invest only in high quality, U.S. dollar-denominated money market
instruments determined by the Sub-adviser to present minimal credit risks in
accordance with procedures established by the Company's Board of Trustees (the
"Board"). To be considered high quality, a security must be rated in accordance
with applicable rules in one of the two highest rating categories for short-term
securities by at least two nationally recognized statistical rating
organizations ("NRSROs") (or one, if only one such NRSRO has rated the security)
or, if the issuer has no applicable short-term rating, determined by the
Sub-adviser to be of equivalent credit quality.
    
 
   
High quality securities are divided into "first tier" and "second tier"
securities. The Fund will invest only in first tier securities. First tier
securities have received the highest rating for short-term debt from at least
two NRSROs, i.e., rated not lower than 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 one, if only one such NRSRO has rated the security) or, if
unrated, are determined to be of equivalent quality as described above. If a
security has been assigned different ratings by different NRSROs, at least two
NRSROs must have assigned the higher rating in order for the Sub-adviser to
determine the security's eligibility for purchase by the Fund.
    
 
The rating criteria of S&P and Moody's, two NRSROs currently rating instruments
of the type the Fund may purchase, are more fully described in "Description of
Debt Ratings" in the Statement of Additional Information.
 
PERMITTED INVESTMENTS. The Fund may invest in the following types of money
market instruments:
 
/ / OBLIGATIONS ISSUED OR GUARANTEED BY THE U.S. AND FOREIGN GOVERNMENTS, THEIR
    AGENCIES AND INSTRUMENTALITIES. These include: direct obligations of the
    U.S. Treasury, such as Treasury bills and notes; obligations backed by the
    full faith and credit of the U.S. government, such as those issued by the
    Government National Mortgage Association; obligations supported primarily or
    solely by the creditworthiness of the issuer, such as securities of Fannie
    Mae (also known as the Federal National Mortgage Association), Freddie Mac
    (also known as the Federal Home Loan Mortgage Corporation) and the Tennessee
    Valley Authority; and similar U.S.-dollar denominated instruments of foreign
    governments, their agencies, authorities and instrumentalities.
 
/ / OBLIGATIONS OF U.S. AND NON-U.S. BANKS, including certificates of deposit,
    bankers' acceptances and similar instruments, when such banks have total
    assets at the time of purchase equal to at least $1 billion.
 
/ / INTEREST-BEARING DEPOSITS IN U.S. COMMERCIAL AND SAVINGS BANKS having total
    assets of $1 billion or less, in principal amounts at each such bank not
    greater than are insured by an agency of the U.S. government, provided that
    the aggregate amount of such deposits (including interest earned) does not
    exceed 5% of the Fund's assets.
 
   
/ / COMMERCIAL PAPER AND OTHER SHORT-TERM DEBT OBLIGATIONS OF U.S. AND FOREIGN
    COMPANIES, rated at least A-1 by S&P or Prime-1 by Moody's or, if not rated,
    determined by the Sub-adviser to be of equivalent quality, provided that any
    outstanding intermediate- or long-term debt of the issuer is rated at least
    AA by S&P or Aa by Moody's. These instruments may include corporate bonds
    and notes (corporate obligations that mature, or that
    
 
                               Prospectus Page 8
<PAGE>
   
                             GT GLOBAL DOLLAR FUND
    
    may be redeemed, in one year or less). These corporate obligations include
    variable rate master notes, which are redeemable upon notice and permit
    investment of fluctuating amounts at varying rates of interest pursuant to
    direct arrangements with the issuer of the instrument.
 
   
/ / REPURCHASE AGREEMENTS SECURED BY ANY OF THE FOREGOING. A repurchase
    agreement is a transaction in which the 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 the Fund
    if the other party to the repurchase agreement becomes bankrupt, the Fund
    will enter into repurchase agreements only with banks and dealers believed
    by the Sub-adviser to present minimal credit risks in accordance with
    guidelines approved by the Board. The Sub-adviser will review and monitor
    the creditworthiness of such institutions under the Board's general
    supervision. The Fund will not enter into repurchase agreements with
    maturities of more than seven days if, as a result, more than 10% of the
    value of its net assets would be invested in such repurchase agreements and
    other illiquid securities.
    
 
   
INVESTMENT TECHNIQUES. In managing the Fund, the Sub-adviser may employ a number
of professional money management techniques, including varying the composition
of the Fund's investments and the average weighted maturity of the Fund's
portfolio within the limitations described above. Determinations to use such
techniques will be based on the Sub-adviser's identification and assessment of
the relative values of various money market instruments and the future of
interest rate patterns, economic conditions and shifts in fiscal and monetary
policy. The Sub-adviser also may seek to improve the Fund's yield by purchasing
or selling securities in order to take advantage of yield disparities that
regularly occur in the market. For example, frequently there are yield
disparities between different types of money market instruments, and market
conditions from time to time result in similar securities trading at different
prices.
    
 
RISKS AND OTHER CONSIDERATIONS. Investors should recognize that in periods of
declining interest rates, the Fund's yield will tend to be somewhat higher than
prevailing market rates; conversely, in periods of rising interest rates, the
Fund's yield will tend to be somewhat lower than those rates. Also, when
interest rates are falling, the net new money flowing into the Fund from the net
sale of its shares likely will be invested in instruments producing lower yields
than the balance of the Fund's portfolio, thereby reducing its yield. The
opposite generally will be true in periods of rising interest rates. The Fund is
designed to provide maximum current income consistent with the liquidity and
safety of principal afforded by investment in a portfolio of high quality money
market instruments; the Fund's yield may be lower than that produced by funds
investing in lower quality and/or longer-term securities.
 
Although the Fund may invest in instruments of non-U.S. issuers, all such
instruments will be denominated in U.S. dollars and will be first tier
securities. Obligations of non-U.S. issuers are subject to the same risks that
pertain to domestic issues, notably credit risk, market risk and liquidity risk.
Nonetheless, these instruments present risks that are different from those
presented by investment in instruments of U.S. issuers. Obligations of foreign
entities may be subject to certain sovereign risks, including adverse political
and economic developments in a foreign country, the extent and quality of
government regulation of financial markets and institutions, interest
limitations, currency controls, foreign withholding taxes, and expropriation or
nationalization of foreign issuers and their assets. There may be less publicly
available information about foreign issuers than about domestic issuers, and
foreign issuers may not be subject to the same accounting, auditing and
financial recordkeeping standards and requirements as are domestic issuers.
Accordingly, while the Fund's ability to invest in these instruments may provide
it with the potential to produce a higher yield than money market funds
investing solely in instruments of domestic issuers, the Fund presents greater
risk than such other funds.
 
VARIABLE AND FLOATING RATE SECURITIES. The Fund may purchase variable and
floating rate securities with remaining maturities in excess of 13 months. Such
securities must comply with conditions established by the SEC under which they
may be considered to have remaining maturities of 13 months or less. The yield
of these securities varies in relation to changes in specific money market rates
such as the prime rate. These changes are reflected in adjustments to the yields
of the variable and floating rate securities, and different
 
                               Prospectus Page 9
<PAGE>
   
                             GT GLOBAL DOLLAR FUND
    
   
securities may have different adjustment rates. To the extent that the Fund
invests in such variable and floating rate securities, it is the Sub-adviser's
view that the Fund may be able to take advantage of the higher yield that is
usually paid on longer-term securities. The Sub-adviser further believes that
the variable and floating rates paid on such securities may substantially reduce
the wide fluctuations in market value caused by interest rate changes and other
factors which are typical of longer-term debt securities.
    
 
OTHER INFORMATION. The Fund may acquire participation interests in securities in
which it is permitted to invest. Participation interests are pro rata interests
in securities held by others. Pending investment of proceeds from new sales of
Fund shares or for temporary defensive purposes, the Fund may hold any portion
of its assets in cash. The Fund may borrow money from banks as a temporary
measure (a) for extraordinary or emergency purposes in amounts up to 5% of its
net assets (taken at market value) or (b) in amounts up to 33 1/3% of its net
assets in order to meet redemption requests. The Fund will not purchase
securities while borrowings remain outstanding. The Fund may invest no more than
5% of its total assets in the securities of a single issuer (other than
securities issued or guaranteed by the U.S. government, its agencies, or
instrumentalities).
 
The Fund's investment objective and policies with respect to borrowing as stated
above are fundamental and may not be changed without the approval of a majority
of its outstanding voting securities. A "majority of the Fund's outstanding
voting securities" means the lesser of (i) 67% of its shares represented at a
meeting at which more than 50% of the outstanding shares are represented, and
(ii) more than 50% of its outstanding shares. In addition, the Fund has adopted
certain investment limitations that also may not be changed without shareholder
approval. A description of these limitations is included in the Statement of
Additional Information. The Fund's other investment policies described herein
are not fundamental and may be changed by vote of the Board without shareholder
approval.
 
On December 29, 1992, the shareholders of the Fund approved modifications to the
Fund's investment policies and limitations that authorize the Board to effect a
change in the operating structure of the Fund, so that it may transfer all of
its investable assets to the Global Dollar Portfolio ("Portfolio"), an open-end
management investment company with substantially the same investment objective,
limitations and policies as the Fund. The Portfolio may serve as the investment
vehicle for different entities that have the same investment objective and
policies as the Fund. By investing in the Portfolio rather than maintaining its
own portfolio of securities, the Fund would expect to realize certain economies
of scale that would arise as additional investors invest their assets in the
Portfolio. There is no assurance that institutional investors will invest in the
Portfolio or that any of these expected benefits would actually be realized by
the Fund. Implementation of this new operating structure will only occur upon
approval of the Board.
 
   
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.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
   
GENERAL. Advisor Class shares are offered through this Prospectus to [(a)
trustees or other fiduciaries purchasing shares for employee benefit plans which
are sponsored by organizations which 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 such account, and (ii) the account holder pays such person as
compensation for its advice and other services an annual fee of at least .50% on
the assets in the account ("Advisory Account"); (c) any account with assets of
at 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 .50% on the assets in the account ("Wrap Fee Account"); (d) accounts
advised by one of the companies composing or affiliated with AMVESCAP PLC; and
(e) any of the companies composing or affiliated with AMVESCAP PLC.] Financial
planners, trust companies, bank trust companies and registered investment
advisers referenced in subpart (b) and sponsors of "wrap fee" programs
referenced in subpart (c) are collectively referred to as "Financial Advisers."
Investors in Wrap Fee Accounts and Advisory Accounts may only purchase Advisor
Class shares through Financial Advisers who have entered into agreements with
AIM Distributors and certain of its affiliates. Investors may be charged a fee
by their agent or broker if they effect transactions other than through a
dealer.
    
 
   
All purchase orders will be executed at the public offering price next
determined after the purchase order is received. Orders received by authorized
institutions (or their designees) before the close of regular trading on the New
York Stock Exchange ("NYSE") (currently 4:00 p.m. Eastern Time, unless weather,
equipment failure or other factors contribute to an earlier closing time) on any
Business Day will be executed at the Fund's net asset value per share determined
that day, provided Federal Funds, as defined below, become available to the Fund
that day. A "Business Day" is any day Monday through Friday on which the NYSE is
open for business. Prior to receipt of Federal Funds, an investor's money will
not be invested. "Federal Funds" are monies held on deposit at a Federal Reserve
Bank that are available for the Fund's immediate use. Purchases by check or
negotiable bank draft normally take two business days to be converted into
Federal Funds. Shares begin accruing income dividends on the day following the
date of purchase. THE FUND AND AIM DISTRIBUTORS RESERVE THE RIGHT TO REJECT ANY
PURCHASE ORDER AND TO SUSPEND THE OFFERING OF SHARES FOR A PERIOD OF TIME. In
particular, the Fund and AIM Distributors may reject purchase orders or
exchanges by investors who appear to follow, in the Sub-adviser's judgment, a
market-timing strategy or otherwise engage in excessive trading. See "How to
Make Exchanges -- Limitations on Purchase Orders and Exchanges."
    
 
   
Fiduciaries and Financial Advisers may be required to provide information
satisfactory to AIM Distributors concerning their eligibility to purchase
Advisor Class shares. For specific information on opening an account, please
contact your Financial Adviser or AIM Distributors.
    
 
   
PURCHASES BY BANK WIRE. Shares of the Fund may also be purchased by bank wire.
Bank wire purchases will be effected at the net asset value next determined
after the bank wire is received. A wire investment is considered received when
the Transfer Agent is notified that the bank wire has been credited to a Fund.
Prior telephonic or facsimile notice must be provided to the Transfer Agent that
a bank wire is being sent. A bank may charge a service fee for wiring money to
the Fund. The Transfer Agent currently does not charge a service fee for
facilitating wire purchases, but reserves the right to do so in the future. For
more information, please refer to the Shareholder Account Manual in this
Prospectus.
    
 
CERTIFICATES. In the interest of economy and convenience, the Fund does not
issue physical certificates representing its shares. Shares of the Fund are
recorded on a register by the Transfer Agent, and shareholders have the same
rights of ownership as if certificates had been issued to them.
 
PORTFOLIO REBALANCING PROGRAM. The GT Global Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of GT Global Mutual
 
                               Prospectus Page 11
<PAGE>
   
                             GT GLOBAL DOLLAR FUND
    
Funds. The Program automatically rebalances holdings of GT Global Mutual 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, GT Global Mutual
Funds ("Personal Portfolio") is to be rebalanced on a monthly, quarterly,
semiannual, or annual basis.
 
Rebalancing under the Program will be effected through the exchange of shares of
one or more GT Global Mutual Funds in the shareholder's Personal Portfolio for
shares of the same class of one or more other GT Global Mutual Funds in the
shareholder's Personal Portfolio. See "How to Make Exchanges." If shares of the
GT Global Mutual Fund(s) in a shareholder's Personal Portfolio have appreciated
during a rebalancing period, the Program will result in shares of GT Global
Mutual Fund(s) that have appreciated most during the period being exchanged for
shares of GT Global Mutual 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 and Federal
Income Taxation." 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 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 a Fund's shares. Exchanges made
under the Program are not subject to the four free exchanges per year
limitation. The 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 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 Financial Institutions
may charge a fee for establishing accounts relating to the Program. Investors
should contact their Financial Institution or AIM Distributors for more
information.

                             HOW TO MAKE EXCHANGES
 
- --------------------------------------------------------------------------------
 
   
Advisor Class shares of the Fund may be exchanged for Advisor Class shares of
any other GT Global Mutual Fund, based on their respective net asset values
without imposition of any sales charges, provided that the registration remains
identical.
    
 
   
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends, Other
Distributions and Federal Income Taxation." The GT Global Mutual Funds include
the following:
    
 
   
  - GT GLOBAL AMERICA SMALL CAP GROWTH FUND
    
   
  - GT GLOBAL AMERICA MID CAP GROWTH FUND

Exchange requests received in good order by the Transfer Agent before the close
of regular trading on the NYSE on any Business Day will be processed at the net
asset value determined that day. The terms of the exchange offer may be modified
at any time, on 60 days' prior written notice.
    
 
   
Investors in Wrap Fee Accounts and Advisory Accounts interested in making an
exchange should contact their Financial Advisers to request the prospectuses of
the other GT Global Mutual Fund(s) being considered. Other investors should
contact AIM Distributors.
    
 
   
EXCHANGES BY TELEPHONE. A shareholder may give exchange information to the
shareholder's Financial Adviser. Shareholders automatically have telephone
privileges to authorize exchanges. The Fund, AIM Distributors and the Transfer
Agent will not be liable for any loss or damage for acting in good faith upon
instructions received by telephone and reasonably believed to be genuine. The
Fund employs reasonable procedures to confirm that instructions communicated by
telephone are genuine prior to acting upon instructions received by telephone,
including requiring some form of personal identification, providing written
confirmation of such transactions, and/or tape recording of telephone
instructions.
    
 
   
LIMITATIONS ON PURCHASE ORDERS AND EXCHANGES. The GT Global Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market-timing
investment strategies and excessive trading can have on efficient portfolio
management, each GT Global Mutual Fund and AIM Distributors reserve the right to
refuse purchase orders and exchanges by any person or group, if, in the
Sub-adviser's judgment such person or group was following a market-timing
strategy or was otherwise engaging in excessive trading.
    
 
   
In addition, each GT Global Mutual Fund and AIM Distributors reserve the right
to refuse purchase orders and exchanges by any person or group if, in the
Sub-adviser's judgment, the Fund would not be able to invest the money
effectively in accordance with that Fund's investment objective and policies or
would otherwise potentially be adversely affected. Although a GT Global Mutual
Fund will attempt to give investors prior notice whenever it is reasonably able
to do so, it may impose the above restrictions at any time.
    
 
   
Finally, as described above, the Fund and AIM Distributors reserve the right to
reject any purchase order.

                              HOW TO REDEEM SHARES
 
- --------------------------------------------------------------------------------
 
   
Redemption requests may be transmitted to the Transfer Agent by telephone or by
mail, in accordance with the instructions provided in the Shareholder Account
Manual. All redemptions will be effected at the net asset value next determined
after the Transfer Agent has received the request, provided that the request is
transmitted to the Transfer Agent prior to the time set for receipt of such
redemption requests. Redemptions will only be effected if the request is
received in good order and accompanied by any required supporting documentation.
Redemption requests will not require a signature guarantee if the redemption
proceeds are to be sent either: (i) to the redeeming shareholder at the
shareholder's address of record as maintained by the Transfer Agent, provided
the shareholder's address of record has not been changed in the preceding
fifteen days; or (ii) directly to a pre-designated bank, savings and loan or
credit union account ("Pre-Designated Account"). ALL OTHER REDEMPTION REQUESTS
MUST BE ACCOMPANIED BY A SIGNATURE GUARANTEE OF THE REDEEMING SHAREHOLDER'S
SIGNATURE. A signature guarantee can be obtained from any bank, U.S. trust
company, a member firm of a U.S. stock exchange or a foreign branch of any of
the foregoing or other eligible guarantor institution. A notary public is not an
acceptable guarantor.
    
 
Shareholders with Pre-Designated Accounts should request that redemption
proceeds be sent either by bank wire or by check. The minimum redemption amount
for a bank wire is $500. Shareholders requesting a bank wire should allow two
business days from the time the redemption request is effected for the proceeds
to be deposited in the shareholder's Pre-Designated Account. See "How to Redeem
Shares -- Other Important Redemption Information." Shareholders may change their
Pre-Designated Accounts only by a letter of instruction to the Transfer Agent
containing all account signatures, each of which must be guaranteed. The
Transfer Agent currently does not charge a bank wire service fee for each wire
redemption sent but reserves the right to do so in the future. The shareholder's
bank may charge a bank wire service fee.
 
REDEMPTIONS BY TELEPHONE. Redemption requests may be made by telephone by
calling the Transfer Agent at the appropriate toll-free number provided in the
Shareholder Account Manual. REDEMPTION REQUESTS MAY NOT BE MADE BY TELEPHONE FOR
FIFTEEN DAYS FOLLOWING ANY CHANGE OF THE SHAREHOLDER'S ADDRESS OF RECORD.
 
   
Shareholders automatically have telephone privileges to authorize redemptions.
The Fund, AIM Distributors and the Transfer Agent will not be liable for any
loss or damage for acting in good faith upon instructions received by telephone
and reasonably believed to be genuine. The Fund employs reasonable procedures to
confirm that instructions communicated by telephone are genuine prior to acting
upon instructions received by telephone, including requiring some form of
personal identification, providing written confirmation of such transactions,
and/or tape recording of telephone instructions.
    
 
REDEMPTIONS BY MAIL. Redemption requests should be mailed directly to the
Transfer Agent at the appropriate address provided in the Shareholder Account
Manual. As discussed above, requests for payment of redemption proceeds to a
party other than the shareholder of record and/or requests that redemption
proceeds be mailed to an address other than the shareholder's address of record
require a signature guarantee. In addition, if the shareholder's address of
record has been changed within the preceding fifteen days, a signature guarantee
is required.
 
   
OTHER IMPORTANT REDEMPTION INFORMATION. A request for redemption will not be
processed until all of the necessary documentation has been received in good
order. A shareholder in doubt about what documents are required should contact
his or her Financial Adviser or the Transfer Agent.
    
 
   
Except in extraordinary circumstances and as permitted under the 1940 Act,
payment for shares
redeemed by telephone or by mail will be made promptly after receipt of a
redemption request, if in good order, but not later than seven days after the
date the request is executed. Requests for

redemption which are subject to any special conditions or which specify a future
or past effective date cannot be accepted.
 
If the Transfer Agent is requested to redeem shares for which the Fund has not
yet received good payment, the Fund may delay payment of redemption proceeds
until the Transfer Agent has assured itself that good payment has been collected
for the purchase of the shares. In the case of purchases by check, it can take
up to 10 business days to confirm that the check has cleared and good payment
has been received. Redemption proceeds will not be delayed when shares have been
paid for by wire or when the investor's account holds a sufficient number of
shares for which funds already have been collected.
 
   
AIM Distributors each reserves the right to redeem the shares of any Advisory
Account or Wrap Fee Account if the amount invested in GT Global Mutual Funds
through such account is reduced to less than $500 through redemptions or other
action by the shareholder. Written notice will be given to the shareholder at
least 60 days prior to the date fixed for such redemption, during which time the
shareholder may increase the amount invested in GT Global Mutual Funds through
such account to an aggregate amount of $500 or more.
    
 
For additional information on how to redeem shares, see the Shareholder Account
Manual in this Prospectus, or contact your Financial Adviser.

                         CALCULATION OF NET ASSET VALUE
 
- --------------------------------------------------------------------------------
 
The Fund intends to use its best efforts to maintain its net asset value at
$1.00 per share. There can be no assurance, however, that it will be able to do
so. The value of each share of the Fund is computed by dividing its net assets
by the number of its outstanding shares. "Net assets" equal the value of the
Fund's investments and other assets less its liabilities. The Fund calculates
its net asset value as of the close of regular trading on the NYSE (currently
4:00 p.m. Eastern Time, unless weather, equipment failure or other factors
contribute to an earlier closing time) each Business Day. Net asset value is
determined separately for each class of the Fund's shares.
 
The Fund values its portfolio securities using the amortized cost method of
valuation, pursuant to which the market value of an instrument is approximated
by amortizing the difference between the acquisition cost and value at maturity
of the instrument on a straight-line basis over its remaining life. All cash,
receivables and current payables are carried at their face value. Other assets,
if any, are valued at fair value as determined in good faith by or under the
direction of the Board.
 
- --------------------------------------------------------------------------------
 
                     DIVIDENDS AND FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS. Dividends are declared daily and paid monthly from the Fund's net
investment income and any realized net short-term capital gain (the excess of
short-term capital gains over short-term capital losses). The Fund's net
investment income includes accrued interest and earned discount (including both
original issue and market discounts), less amortization of premium and
applicable expenses. Fund shares begin to earn dividends on the day following
the day on which Federal Funds become available. Dividends paid by the Fund with
respect to all classes of its shares are calculated in the same manner and at
the same time. The per share dividends on Advisor Class shares will be higher
than the per share dividends on shares of other classes of the Fund as a result
of the 12b-1 service and distribution fees applicable to those shares.
 
Dividends are automatically reinvested in Advisor Class shares unless the
investor has elected to receive them in cash. Cash payments may be elected on
the Account Application located at the end of this Prospectus or through the
investor's broker/ dealer. Reinvestments in Advisor Class shares of another GT
Global Mutual Fund may only be directed to an account with an identical
shareholder registration and account number. An election to receive dividends in
additional shares or in cash may be changed at any time, but, to be effective
for a particular dividend, the investor or the investor's broker/dealer must
notify the Transfer Agent at least fifteen Business Days prior to the payment
date. Shares earn dividends on the day of redemption. THE FEDERAL INCOME TAX
STATUS OF DIVIDENDS IS THE SAME WHETHER THEY ARE RECEIVED IN CASH OR REINVESTED
IN ADDITIONAL SHARES.
 
The Fund does not expect to realize long-term capital gain and thus does not
anticipate payment of any capital gain distributions.
 
TAXES. The Fund intends to continue to qualify for treatment as a regulated
investment company under the Internal Revenue Code of 1986, as amended. In each
taxable year that the Fund so qualifies, the Fund (but not its shareholders)
will be relieved of federal income tax on that part of its investment company
taxable income (consisting of net investment income and any net short-term
capital gain) that is distributed to its shareholders. Those distributions are
taxable to the Fund's shareholders as ordinary income to the extent of its
 
                               Prospectus Page 17

                             GT GLOBAL DOLLAR FUND
    
earnings and profits, whether they are received in cash or reinvested in
additional shares.
 
The Fund provides federal income tax information to its shareholders annually,
including information about dividends paid during the preceding year.
 
The Fund must withhold 31% of all dividends payable to any individuals and
certain other noncorporate shareholders who (1) have not furnished to the Fund a
correct taxpayer identification number or a properly completed claim for
exemption on Form W-8 or W-9 or (2) otherwise are subject to backup withholding.
 
Taxpayer identification numbers may be furnished on the Account Application
provided at the end of this Prospectus. Fund accounts opened via a bank wire
purchase (see "How to Invest -- Purchases Through the Distributor") are
considered to have uncertified taxpayer identification numbers unless a
completed Form W-8 or W-9 or Account Application is received by the Transfer
Agent within seven days after the purchase. A shareholder should contact the
Transfer Agent if the shareholder is uncertain whether a proper taxpayer
identification number is on file with the Fund.
 
The foregoing is only a summary of some of the important federal income tax
considerations generally affecting the Fund and its shareholders. See "Dividends
and Taxes" in the Statement of Additional Information for a further discussion.
There may be other federal, state, local or foreign tax considerations
applicable to a particular investor. Prospective investors are therefore urged
to consult their tax advisers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
   
The Company's Board of Trustees has overall responsibility for the operation of
the Fund. The Company's Board of Trustees has approved all significant
agreements between the Company on the one side and persons or companies
furnishing services to the Fund on the other, including the investment advisory
and administrative services agreement with AIM, the investment sub-advisory and
sub-administration agreement with the Sub-adviser, the agreements with AIM
Distributors regarding distribution of the Fund's shares, the agreement with
State Street Bank and Trust Company as the custodian and the transfer agency
agreement with GT Global Investors Services, Inc., an affiliate of the
Sub-adviser. The day-to-day operations of the Fund are delegated to the officers
of the Company, subject always to the objective and policies of the Fund and to
the general supervision of the Company's Board of Trustees. See "Trustees and
Executive Officers" in the Statement of Additional Information for information
on the 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
management and administration fees, computed daily and paid monthly, at the
annualized rate of 0.50% of the Fund's average daily net assets. 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. AIM has undertaken to limit the
Fund's expenses (exclusive of brokerage commissions, interests, taxes and
extraordinary expenses) to the annual rate of 1.00% 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 at an annual rate derived by
applying 0.03% to the first $5 billion of assets of GT Global Funds and 0.02% to
the assets in excess of $5 billion and allocating the result according to the
Fund's average daily net assets.
    
 
   
AIM, 11 Greenway Plaza, Suite 100, Houston, Texas 77046, serves as the
investment adviser to the Fund pursuant to a master investment advisory
agreement, dated as of               , 1998 (the "Advisory Agreement"). AIM was
organized in 1976 and, together with its subsidiaries, manages or advises [over
50] 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 agreement dated as of
              , 1998. On May   , 1998, Liechtenstein Global Trust AG ("GT"), the
former indirect parent organization of the Sub-adviser, consummated a purchase
agreement with AMVESCAP PLC pursuant to which AMVESCAP PLC acquired GT's Asset
Management Division, which includes 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 GT Global Mutual
Funds, the Sub-adviser employs a team approach, taking advantage of its
investment resources around the world in seeking each Fund's investment
 
objective.
    
 
   
The investment professionals primarily responsible for the portfolio management
of the Fund are as follows:

                                                         From July 1995 to October 1996, Mr. Lau was employed by

                                                         employed by Chancellor Capital.

                            ------------------------
 
   
In placing 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 dealer's sale of shares of the
GT Global Mutual Funds as a factor in considering through whom portfolio
transactions will be effected.
    
 
   
DISTRIBUTION OF FUND SHARES. AIM Distributors is the distributor of the Fund's
Advisor Class shares. AIM Distributors is a wholly owned subsidiary of AIM. The
address of AIM Distributors is P.O. Box 4739, Houston, Texas 77210-4739. The
Sub-adviser or an affiliate thereof may, from time to time, make ongoing
payments to Financial Advisors and others that facilitate the administration and
servicing of Advisor Class shareholder accounts.
    
 
   
AIM Distributors, at its own expense, may provide additional promotional
incentives to broker/ dealers that sell shares of the Fund and/or shares of the
other GT Global Mutual Funds. In some instances additional compensation or
promotional incentives may be offered to broker/dealers that have sold or may
sell significant amounts of shares during specified periods of time. Such
compensation and incentives may include, but are not limited to, cash,
merchandise, trips and financial

assistance to broker/dealers in connection with preapproved conferences or
seminars, sales or training programs for invited sales personnel, payment for
travel expenses (including meals and lodging) incurred by sales personnel and
members of their families or other invited guests to various locations for such
seminars or training programs, seminars for the public, advertising and sales
campaigns regarding one or more of the GT Global Mutual Funds, and/or other
events sponsored by the broker/dealers.
 
   
The Glass-Steagall Act and other applicable laws, among other things, generally
prohibit federally chartered or supervised banks from engaging in the business
of underwriting or distributing securities. Accordingly, AIM Distributors
intends to engage banks (if at all) only to perform administrative and
shareholder servicing functions. Banks and broker/dealer affiliates of banks
also may execute dealer agreements with AIM Distributors for the purpose of
selling shares of the Fund. If a bank were prohibited from so acting, its
shareholder clients would be permitted to remain shareholders, and alternative
means for continuing the servicing of such shareholders would be sought. It is
not expected that shareholders would suffer any adverse financial consequences
as a result of any of these occurrences.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
STATEMENTS AND REPORTS TO SHAREHOLDERS. Shareholders receive monthly statements
from the Transfer Agent detailing account transactions, such as an additional
investment, redemption or the payment of a dividend. Shortly after the end of
the Fund's fiscal year on December 31 and fiscal half-year on June 30 of each
year, shareholders receive an annual and semiannual report, respectively. These
reports list the securities held by the Fund and contain its financial
statements. In addition, the federal income status of dividends paid by the Fund
to its shareholders is reported after the end of each calendar year on Form
1099-DIV. Under certain circumstances, duplicate mailings of the foregoing
reports to the same household may be consolidated.
 
   
ORGANIZATION OF THE COMPANY. The Company was organized as a Delaware business
trust on May   , 1998. Prior to June 1, 1998, the Company operated under the
name of "G.T. Investment Portfolios, Inc.", a Maryland corporation organized in
1981. From time to time, the Board may, at its discretion, establish additional
funds, each corresponding to a distinct investment portfolio and a distinct
series of the Company's shares.
    
 
Advisor Class shares are offered through this prospectus to certain investors.
The Fund also offers Class A shares and Class B shares to investors through a
separate prospectus. The different expenses borne by each class of shares will
result in different dividends. The per share dividends on Advisor Class shares
of the Fund will generally be higher than the per share dividends on Class A and
B shares of the Fund as a result of the service and distribution fees applicable
with respect to Class A and B shares. Consequently, during comparable periods,
the Fund expects that the total return on an investment in shares of the Advisor
Class will be higher than the total return on Class A and B shares.
 
   
Pursuant to the Company's Declaration of Trust, it 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 other distributions out of the income earned and gain realized on
the assets belonging to the Fund as may be declared at the discretion of the
Board of Trustees. Each share of the Fund is equal as to earnings, assets and
voting privileges except that each class has exclusive voting rights with
respect to its distribution and bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund when issued are fully paid and
nonassessable.
    
 
   
Fund shares are entitled to one vote per share (with proportional voting for
fractional shares) and are freely transferable. Shareholders have no preemptive
or conversion rights. Shares may be voted on the election of Trustees and on
other matters submitted to the vote of Fund shareholders. If one or more
additional funds were established,

<PAGE>
   
                             GT GLOBAL DOLLAR FUND
    
   
on any matter submitted to a vote of shareholders, shares of each fund would be
voted by that fund's shareholders individually when the matter affected the
specific interest of that fund only, such as approval of that fund's investment
advisory arrangements. In addition, shares of a particular class of the Fund may
vote on matters affecting only that class. The shares of all the Company's funds
would be voted in the aggregate on other matters, such as the election of
Trustees and ratification of the Directors' 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. The Company would be required to hold a
shareholders' meeting in the event that at any time less than a majority of the
Trustees holding office had been elected by shareholders. Trustees shall
continue to hold office until their successors are elected and have qualified.
Shares of the Company's funds 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 upon a majority vote of the
shareholders qualified to vote in the election. Shareholders holding 10% of the
Company's outstanding voting securities may call a meeting of shareholders for
the purpose of voting upon the question of removal of any Trustee or for any
other purpose. The 1940 Act requires the Company to assist shareholders in
calling such a meeting.
    
 
SHAREHOLDER INQUIRIES. Shareholder inquiries may be made by calling the Fund at
(800) 223-2138 or by writing to the Fund at 50 California Street, 27th Floor,
San Francisco, CA 94111.
 
PERFORMANCE INFORMATION. From time to time the Fund may advertise its "yield"
and "effective yield" in advertisements or promotional materials ("Performance
Advertisements"). Both yield and effective yield are calculated separately for
Class A, Class B and Advisor Class shares of the Fund. Both yield figures are
based on historical earnings and are not intended to indicate future
performance. It can be expected that these yields will fluctuate substantially.
The "yield" of the Fund refers to the income generated by an investment in the
Fund over a seven-day period (which period will be stated in the advertisement).
This income is then "annualized." That is, the amount of income generated by the
investment during that week is assumed to be generated each week over a 52-week
period and is shown as a percentage of the investment. The "effective yield" is
calculated similarly but, when annualized, the income earned by an investment in
the Fund is assumed to be reinvested. The "effective yield" will be slightly
higher than the "yield" because of the compounding effect of this assumed
reinvestment. The Fund's "yield" and "effective yield" may reflect expenses
after reimbursement pursuant to an undertaking that may be in effect. See
"Management." The Statement of Additional Information describes the methods used
to calculate the Fund's yield and effective yield.
 
In Performance Advertisements, the Fund may quote its average annual total
return ("Standardized Return"). Standardized Return is calculated separately for
each class of shares of the Fund. Standardized Return shows percentage rates
reflecting the average annual change in the value of an assumed investment in
the Fund at the end of one-, five-, and ten-year periods, reduced by the maximum
applicable sales charge imposed on sales of Fund shares. If a one-, five- and/or
ten-year period has not yet elapsed, data will be provided as to the end of a
shorter period corresponding to the life of the Fund. Standardized Return
assumes reinvestment of all dividends and capital gain distributions.
 
In addition, in order to more completely represent the Fund's performance or
more accurately compare such performance to other measures of investment return,
the Fund also may include in advertisements, sales literature and shareholder
reports other total return performance data ("Non-Standardized Return").
Non-Standardized Return reflects percentage rates of return encompassing all
elements of return; it assumes reinvestment of all dividends and capital gain
distributions. Non-Standardized Return may be quoted for the same or different
periods as those for which Standardized Return is quoted; it may consist of an
aggregate or average annual percentage rate of return, actual year-by-year rates
or any combination thereof. Non-Standardized Return may or may not take sales
charges into account; performance data calculated without taking the effect of
sales charges into account will be higher than data including the effect of such
charges.
 
The Fund's performance data reflects past performance and is not necessarily
indicative of future results. The Fund's investment results will vary from time
to time depending upon market conditions, the composition of its portfolio and
its operating expenses. These factors and possible differences in calculation
methods should be considered when

                             GT GLOBAL DOLLAR FUND
    
comparing the Fund's investment results with those published for other
investment companies, other investment vehicles and unmanaged indices. The
Fund's results also should be considered relative to the risks associated with
its investment objective and policies. See "Investment Results" in the Statement
of Additional Information.
 
   
YEAR 2000 COMPLIANCE PROJECT. In providing services to the GT Global Mutual
Funds, AIM, AIM Distributors, the Transfer Agent and the Sub-adviser rely on
internal computer systems as well as external computer systems provided by third
parties. Some of these systems were not originally designed to distinguish
between the year 1900 and the year 2000. This inability, if not corrected, could
adversely affect the services AIM Distributors, the Transfer Agent and the
Sub-adviser and others provide the GT Global Mutual Funds and their
shareholders.
    
 
   
To address this important issue, AIM, AIM Distributors, the Transfer Agent and
the Sub-adviser have undertaken a comprehensive Year 2000 Compliance Project
(the "Project"). The Project consists of four phases: (i) inventorying every
software and hardware system in use at AIM, AIM Distributors, the Transfer Agent
and the Sub-adviser, as well as remote, third-party systems on which AIM, AIM
Distributors, the Transfer Agent and the Sub-adviser rely; (ii) identifying
those systems that may not function properly after December 31, 1999; (iii)
correcting or replacing those systems that have been so identified; and (iv)
testing the processing of GT Global Mutual Fund data in all systems. Phase (i)
has been completed; phase (ii) is substantially completed; phase (iii) has
commenced; and phase (iv) is expected to commence during the third quarter of
1998. The Project is scheduled to be completed by December 31, 1998. Following
completion of the Project, AIM, AIM Distributors and the Sub-adviser will ensure
that any systems subsequently acquired are year 2000 compliant.
    
 
   
TRANSFER AGENT. Shareholder servicing, reporting and general transfer agent
functions for the Fund are performed by GT Global Investor Services, Inc. The
Transfer Agent is an affiliate of the Sub-adviser and AIM, a subsidiary of
Liechtenstein Global Trust and maintains offices at California Plaza, 2121 North
California Boulevard, Suite 450, Walnut Creek, CA 94596.
    
 
CUSTODIAN. State Street Bank and Trust Company, 225 Franklin Street, Boston, MA
02110 is custodian of the Fund's assets.
 
   
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
N.W., Washington, D.C., 20036-1800, acts as counsel to the Company. Kirkpatrick
& Lockhart LLP also acts as counsel to the Sub-adviser, GT Global and the
Transfer Agent in connection with other matters.
    
 
   
INDEPENDENT ACCOUNTANTS. The Company's and the Fund's independent accountants
are                        , One Post Office Square, Boston, MA 02109.
                       conducts an annual audit of the Fund, assists in the
preparation of the Fund's federal and state income tax returns and consults with
the Company and the Fund as to matters of accounting, regulatory filings, and

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVE
The investment objective of the Fund is maximum current income consistent with
liquidity and conservation of capital. The Fund seeks its objective by investing
in high quality, U.S. dollar-denominated money market instruments.
 
CHANGES IN A SECURITY'S RATING
   
Subsequent to the purchase of a security by the Fund, the security may cease to
be rated or its rating may be reduced below the minimum rating required for its
purchase, as described in the Prospectus. In such event the Fund, the Company's
Board of Trustees (the "Board") and the Sub-adviser will review the situation
and take appropriate action in accordance with procedures adopted by the Board
pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended (the
"1940 Act").
    
 
VARIABLE AND FLOATING RATE OBLIGATIONS
Floating and variable rate demand notes and bonds are obligations ordinarily
having stated maturities in excess of 13 months, but which permit the holder to
demand payment of principal at any time, or at specified intervals not exceeding
13 months, in each case upon not more than 30 days' notice. The issuer of such
obligations generally has a corresponding right, after a given period, to prepay
in its discretion the outstanding principal amount of the obligation plus
accrued interest upon a specified number of days' notice to the holders thereof.
The interest rates payable on certain securities in which the Fund may invest
are not fixed and may fluctuate based upon changes in market rates. Variable and
floating rate obligations have interest rates that are adjusted at designated
intervals or whenever there are changes in the market rates of interest on which
the interest rates are based. Variable and floating rate obligations permit the
Fund to "lock in" the current interest rate for only the period until the next
rate adjustment, but the rate adjustment feature tends to limit the extent to
which the market value of the obligation will fluctuate.
 
BANKERS' ACCEPTANCES
Bankers' acceptances are negotiable obligations of a bank to pay a draft which
has been drawn on it by a customer. These obligations are backed by large banks
and usually are backed by goods in international trade.
 
CERTIFICATES OF DEPOSIT
Certificates of deposit are negotiable certificates representing a commercial
bank's obligations to repay funds deposited with it, earning specified rates of
interest over a given period of time.
 
COMMERCIAL PAPER
Commercial paper consists of short-term promissory notes issued by large
corporations with a high quality rating to finance short-term credit needs.
 
U.S. GOVERNMENT OBLIGATIONS
U.S. government obligations are debt securities issued or guaranteed by the U.S.
Treasury or by an agency or instrumentality of the U.S. government. However, not
all U.S. government obligations are backed by the full faith and credit of the
United States. For example, securities issued by the Federal National Mortgage
Association, the Federal Home Loan Mortgage Corporation and the Tennessee Valley
Authority are supported only by the credit of the issuer. There is no guarantee
that the U.S. government will provide support to such U.S. government sponsored
agencies, as it is not so obligated by law. Therefore, the purchase of such
securities involves more risk than investment in other U.S. government
obligations.
 
REPURCHASE AGREEMENTS
   
A repurchase agreement is a transaction in which the 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 the Fund if the other party
to the repurchase agreement becomes bankrupt, the Fund intends to enter into
repurchase agreements only with banks and dealers believed by the Sub-adviser to
present
    
 
                   Statement of Additional Information Page 2
<PAGE>
                             GT GLOBAL DOLLAR FUND
   
minimal credit risks in accordance with guidelines established by the Board. The
Sub-adviser will review and monitor the creditworthiness of such institutions
under the Board's general supervision.
    
 
The Fund 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 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 the 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, the Fund intends to comply with provisions
under that code that would allow the immediate resale of such collateral. There
is no limitation on the amount of the Fund's assets that may be subject to
repurchase agreements at any given time. The 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 its net assets would be invested in such
repurchase agreements and other illiquid investments.
 
WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS
The Fund may buy and sell securities on a when-issued or delayed delivery basis,
with payment and delivery taking place at a future date. The market value of
securities purchased in this way may change before the delivery date, which
could increase fluctuations in the Fund's yield. Ordinarily, the Fund will not
earn interest on securities purchased until they are delivered.
 
ILLIQUID SECURITIES
   
The Fund will not invest more than 10% of its net assets in illiquid securities.
The term "illiquid securities" for this purpose means securities that cannot be
disposed of within seven days in the ordinary course of business at
approximately the amount at which the Fund has valued the securities and
includes, among other things, repurchase agreements maturing in more than seven
days, and restricted securities other than those the Sub-adviser has determined
to be liquid pursuant to guidelines established by the Board. Commercial paper
issues in which the Fund may invest include securities issued by major
corporations without registration under the Securities Act of 1933, as amended
(the "1933 Act"), in reliance on the exemption from such registration afforded
by Section 3(a)(3) thereof and commercial paper issued in reliance on the so-
called "private placement" exemption from registration afforded by Section 4(2)
of the 1933 Act ("Section 4(2) paper"). Section 4(2) paper is restricted as to
disposition under the federal securities laws in that any resale must similarly
be made in an exempt transaction. Section 4(2) paper is normally resold to other
institutional investors through or with the assistance of investment dealers who
make a market in Section 4(2) paper, thus providing liquidity.
    
 
Not all restricted securities are illiquid. In recent years a large
institutional market has developed for certain securities that are not
registered under the 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 on or 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, 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 the 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 Board 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 (1) the frequency of trading in the security; (2)
the number of dealers that make quotes for the security; (3) the number of
dealers that have undertaken to make a market in the security; (4) the number of
other potential purchasers; and (5) the nature of the security and how trading
is effected (E.G., the time needed to sell the security, how offers are
    
 
                   Statement of Additional Information Page 3
<PAGE>
                             GT GLOBAL DOLLAR FUND
   
solicited and the mechanics of transfer). The Sub-adviser monitors the liquidity
of securities held by the Fund and periodically reports such determinations to
the Board as applicable. If the liquidity percentage restriction of the 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
the 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.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
The Fund has adopted the following investment limitations as fundamental
policies that may not be changed without approval by the affirmative vote of 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, and (ii) more than 50% of
the Fund's outstanding shares. The Fund may not:
 
   
        (1) Purchase securities of any one issuer if, as a result, more than 5%
    of the Fund's total assets would be invested in securities of that issuer or
    the Fund would own or hold more than 10% of the outstanding voting
    securities of that issuer, except that up to 25% of the 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;
    
 
   
        (2) 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;
    
 
   
        (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) 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 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) 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;
    
 
   
        (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; or
    
 
   
        (7) 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;
    
 
   
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.

<PAGE>
                             GT GLOBAL DOLLAR FUND
 
   
For purposes of the concentration policy contained in limitation (7), above, the
Fund intends to comply with the Securities and Exchange Commission ("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.
    
 
If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values or assets
will not constitute a violation of that restriction.
 
   
The following investment policies of the 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) Invest more than 10% of its net assets in illiquid securities;
    
 
   
        (2) 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; 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.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
INVESTMENT MANAGEMENT AND ADMINISTRATION SERVICES
   
AIM serves as the Fund's investment manager and administrator under an
Investment Management and Administration Contract between the Company and AIM
("Management Contract"). The Sub-adviser serves as the sub-adviser and sub-
administrator to the 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
Fund and administer the 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 Company and the Fund, and provide suitable office space,
necessary small office equipment and utilities.
    
 
   
The Management Contracts may be renewed for one-year terms with respect to the
Fund, provided that any such renewal has been specifically approved at least
annually by: (i) the Board, or by the vote of a majority of the 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. Either the
Company 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).
    
 
   
For the fiscal years ended December 31, 1997, 1996 and 1995, the Fund paid
investment management and administration fees to the Sub-adviser in the amounts
of $1,384,735, $1,808,976 and $1,665,299, respectively. During the fiscal years
ended December 31, 1997 and 1996, the Sub-adviser reimbursed the Fund for a
portion of its investment management and administration fees in the amounts of
$88,707 and $173,045, respectively. No such reimbursements were made during the
fiscal year ended December 31, 1995.
    
 
DISTRIBUTION SERVICES
   
The Fund's Class A and Class B shares are offered continuously through the
Fund's principal underwriter and distributor, AIM Distributors, on a "best
efforts" basis pursuant to a Distribution Contract between the Company and AIM
Distributors.
    
 
   
As described in the Prospectus, on         , 1998, the Company adopted a Master
Distribution Plan pursuant to Rule 12b-1 under the 1940 Act relating to the
Class A shares of the Fund (the "Class A Plan"). At the same time, the Company
also adopted a Master Distribution Plan pursuant to Rule 12b-1 under the 1940
Act relating to Class B shares of the Fund (the "Class B Plan," and together
with the Class A Plan, the "Plans"). The rate of payments by the Funds under the
Plans, as described in the Prospectus, may not be increased without the approval
of the majority of the outstanding voting securities of the affected class. For
the fiscal year ended December 31, 1997, the Fund made payments to GT Global,
Inc., the Fund's former Distributor, under the Class A Plan and Class B Plan in
the amounts of $422,808 and $995,797, respectively. During the fiscal year ended
December 31, 1997, GT Global waived payments under the Class A Plan and Class B
Plan in the amounts of $422,808 and $248,949, respectively.
    
 
   
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 Fund's 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
Fund. 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 several special investment plans offered in connection with the
purchase of the Fund's 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 Fund's shares; and providing such other information and
services as the Fund or the customer may reasonably request.

<PAGE>
                             GT GLOBAL DOLLAR FUND
 
   
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 that 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 Fund and the
Company; 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 Fund reasonably may
request, to the extent permitted by applicable statute, rule or regulation.
Similar agreements may be permitted under the Plans for institutions that
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, the 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 will be
calculated at the end of each payment period for each business day of the 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 the 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 Fund to no more
than 0.25% per annum of the average daily net assets of the Fund 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 Fund, in
making dealer incentive and shareholder servicing payments under the Plans.
These payments are an obligation of the Fund and not of AIM Distributors.
    
 
   
In approving the Plans, the Trustees determined that the adoption of each Plan
was in the best interests of the shareholders of the Fund. Agreements related to
the Plans must also be approved by such vote of the Trustees, including a
majority of Trustees who are not interested persons of the Company (as defined
in the 1940 Act) and who have no direct or indirect financial interests in the
operation of the Plans, or in any agreement related thereto.
    
 
   
Each Plan requires that, at least quarterly, the Trustees review the amounts
expended thereunder and the purposes for which such expenditures were made. Each
Plan requires that as long as it is in effect the selection and nomination of
Trustees who are not "interested persons" of the Company will be committed to
the discretion of the Trustees who are not "interested persons" of the Company,
as defined in the 1940 Act.
    
 
   
As discussed in the Prospectus, AIM Distributors receives no compensation or
reimbursements relating to its distribution efforts with respect to Class A
shares other than as described above. AIM Distributors receives any contingent
deferred sales charges "CDSCs" payable with respect to redemption of Class B
shares. For the fiscal years ended December 31, 1997, 1996 and 1995, GT Global
collected contingent deferred sales charges in the amount of $1,241,407,
$968,357 and $1,333,734, respectively.
    
 
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The Transfer Agent has been retained by the Fund to perform shareholder
servicing, reporting and general transfer agent functions for the Fund. For
these services, the Transfer Agent receives an annual maintenance fee of $17.50
per account, a new account fee of $4.00 per account, a per transaction fee of
$1.75 for all transactions other than exchanges and a per exchange fee of $2.25.
The Transfer Agent also is reimbursed by the Fund for its out-of-pocket expenses
for such items as postage, forms, telephone charges, stationery and office
supplies. The Sub-adviser also serves as the Fund's pricing and accounting
agent. For the fiscal years ended December 31, 1997, 1996 and 1995, the
accounting services fees for the Fund were $69,517, $90,682 and $86,710,
respectively.

EXPENSES OF THE FUND
   
The Fund 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,
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 Company
expenses and expenses shared among the Fund 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 Fund or the nature of the service
performed and relative applicability to the 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.

                              DIVIDENDS AND TAXES
 
- --------------------------------------------------------------------------------
 
DAILY INCOME DIVIDENDS
Net investment income and any realized net short-term capital gain are
determined and declared as a dividend each day. Each such dividend is payable to
shareholders as of the close of business on that day. Orders to purchase Fund
shares are executed on the business day on which Federal Funds, i.e., monies
held on deposit at a Federal Reserve Bank, become available. Shares begin
accruing dividends on the day following the date of purchase. Shares are
entitled to the dividend declared on the day a redemption request is received by
the Transfer Agent. Dividends are automatically reinvested in Fund shares of the
distributing class on the last Business Day of the month, at net asset value,
unless a shareholder otherwise instructs the Transfer Agent in writing. A
shareholder that does so will be mailed a check in the amount of each dividend.
For the purpose of calculating dividends, daily net investment income of the
Fund consists of (a) all interest income accrued on investments (including any
discount or premium ratably accrued or amortized, respectively, to the date of
maturity or determined in such other manner the Fund chooses in accordance with
generally accepted accounting principles), (b) minus all accrued liabilities,
including interest, taxes and other expense items, and reserves for contingent
or undetermined liabilities, all determined in accordance with those principles,
(c) plus or minus all realized gains or losses on investments, if any.
 
TAXES -- GENERAL
To continue to qualify for treatment as a regulated investment company under the
Internal Revenue Code of 1986, as amended (the "Code"), the Fund must distribute
to its shareholders for each taxable year at least 90% of its investment company
taxable income (consisting of net investment income and any net short-term
capital gain) 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 and gains from the sale or other
disposition of securities, or other income derived with respect to its business
of investing in securities; and (2) the Fund must diversify its holdings so
that, at the close of each quarter of its taxable year, (i) at least 50% of the
value of its total assets is represented by cash and cash items, U.S. government
securities and other securities limited, with respect to any one issuer, to an
amount that does not exceed 5% of the value of the Fund's total assets and (ii)
not more than 25% of the value of its total assets is invested in the securities
of any one issuer (other than U.S. government securities).
 
The Fund will be subject to a nondeductible 4% 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, if any, for the one-year
period ending on October 31 of that year, plus certain other amounts.
 
Dividends from the Fund's investment company taxable income are taxable to its
shareholders as ordinary income. The Fund does not expect to receive any
dividend income from U.S. corporations, which means that no part of the
dividends from the Fund will not be eligible for the dividends-received
deduction allowed to corporations. Dividends will be taxed for federal income
tax purposes in the same manner whether they are received in cash or reinvested
in additional Fund shares.

NON-U.S. SHAREHOLDERS
Dividends paid by the 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 (a "foreign shareholder") will be
subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder is "effectively connected with the conduct of a U.S. trade or
business," in which case the reporting and withholding requirements applicable
to U.S. citizens or other domestic taxpayers will apply.
 
The foregoing is a general and abbreviated summary of certain federal tax
considerations affecting the 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 an investment in the
Fund.

                             SALES AND REDEMPTIONS
 
- --------------------------------------------------------------------------------
 
STATEMENTS AND REPORTS
When an investor makes an initial investment in the Fund, a shareholder account
is opened in accordance with the investor's registration instructions.
Shareholders receive monthly statements detailing account transactions. Shortly
after the end of the Fund's fiscal year on December 31 and fiscal half-year on
June 30, shareholders receive an annual and semiannual report, respectively.
These reports list the securities held by the Fund and contain the Fund's
financial statements. In addition, the federal income tax status of dividends
paid by the Fund to shareholders is reported after the end of each calendar year
on Form 1099-DIV.
 
PAYMENT AND TERMS OF OFFERING
Payment for Class A and Class B shares should accompany the purchase order, or
funds should be wired to the Transfer Agent as described in the Prospectus.
Payment, other than by wire transfer, must be made by check or money order drawn
on a U.S. bank. Checks or money orders must be payable in U.S. dollars.
 
As a condition of this offering, if an order to purchase either class of shares
is cancelled due to nonpayment (for example, because a check is returned for
insufficient funds), the person who made the order will be responsible for any
loss incurred by the Fund by reason of such cancellation, and if such purchaser
is a shareholder, the Fund shall have the authority as agent of the shareholder
to redeem shares in his or her account for their then-current net asset value
per share to reimburse the Company for the loss incurred. Investors whose
purchase orders have been cancelled due to nonpayment may be prohibited from
placing future orders.
 
The Fund reserves the right at any time to waive or increase the minimum
requirements applicable to initial or subsequent investments with respect to any
person or class of persons. An order to purchase shares is not binding on the
Fund until it has been confirmed in writing by the Transfer Agent (or other
arrangements made with the Fund, in the case of orders utilizing wire transfer
of funds, as described above) and payment has been received. To protect existing
shareholders, the Fund reserves the right to reject any offer for a purchase of
shares by any individual.
 
AUTOMATIC INVESTMENT PLAN
To establish participation in the Fund's Automatic Investment Plan ("AIP"),
investors or their broker/dealers should send the following documents to the
Transfer Agent: (1) an AIP Application; (2) a Bank Authorization Form; and (3) a
voided personal check from the pertinent bank account. The necessary forms are
provided at the back of the Prospectus. Provided that an investor's bank accepts
the Bank Authorization Form, investment amounts will be drawn on the designated
dates (monthly on the 25th day or beginning quarterly on the 25th day of the
month the investor first selects) in order to purchase full and fractional
shares of the Fund at the public offering price determined on that day. If the
25th day falls on a Saturday, Sunday or holiday, shares will be purchased on the
next business day. If an investor's check is returned because of insufficient
funds or a stop payment order or if the account is closed, the AIP may be
discontinued, and any share purchase made upon deposit of such check may be
cancelled. Furthermore, the shareholder will be liable for any loss incurred by
the Fund by reason of such cancellation. Investors should allow one month for
the establishment of an AIP. An AIP may be terminated by the Transfer Agent or
the Fund upon thirty days' written notice or by the participant at any time
without penalty, upon written notice to the Fund or the Transfer Agent.

WHEN ORDERS ARE EFFECTIVE
In order to maximize earnings on its portfolio, the Fund intends at all times to
be as completely invested as reasonably possible. Transactions in the money
market instruments in which the Fund invests normally require immediate
settlement in Federal Funds, as defined above. Thus, an order to purchase Fund
shares will be executed on any day Monday through Friday on which the New York
Stock Exchange ("NYSE") is open for business ("Business Day"), on which Federal
Funds become available to the Fund. Funds transmitted by bank wire to the
Transfer Agent and received by it prior to the close of regular trading on the
NYSE will normally be credited to a shareholder's account on the same day as
received. Funds transmitted by bank wire and received after the close of regular
trading on the NYSE normally will be credited on the next Business Day. If
remitted in other than the foregoing manner, such as by check, purchase orders
will be executed as of the close of business on the day on which the payment is
converted into Federal Funds, normally two days after receipt of the payment.
The investor becomes a shareholder on the day on which the order is effective.
Dividends begin to accrue on the next day. Information on how to transmit
Federal Funds by wire is available at any national bank or any state bank that
is a member of the Federal Reserve System. Any such bank may charge the
shareholder for this service.
 
   
CONVERSION OF CLASS B SHARES
    
   
Class B shares will automatically convert into Class A shares of the same Fund.
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 would not be converted and would continue to be
subject to the higher ongoing expenses of the Class B shares beyond the eighth
year. The Sub-adviser has no reason to believe that this condition for the
availability of the conversion feature will not be met.
    
 
INDIVIDUAL RETIREMENT ACCOUNTS ("IRAS") AND OTHER TAX-DEFERRED PLANS
Class A or Class B shares may be purchased as the underlying investment for an
IRA meeting the requirements of Sections 408(a), 408A or 530 of the Code, as
well as for qualified retirement plans described in Code Section 401 and
custodial accounts complying with Code Section 403(b)(7).
 
   
IRAS: If you have earned income from employment (including self-employment), you
can contribute each year to an IRA up to the lesser of (1) $2,000 for yourself
or $4,000 for you and your spouse, regardless of whether your spouse is
employed, or (2) 100% of compensation. Some individuals may be able to take an
income tax deduction for the contribution. Regular contributions may not be made
for the year you become 70 1/2 or thereafter. Unless your and your spouse's
earnings exceed a certain level, you also may establish an "education IRA"
and/or a "Roth IRA." Although contributions to these new types of IRAs are
nondeductible, withdrawals from them will be tax-free under certain
circumstances. Please consult your tax adviser for more information. IRA
applications are available from brokers or AIM Distributors.
    
 
ROLLOVER IRAS: Individuals who receive distributions from qualified retirement
plans (other than required distributions) and who wish to keep their savings
growing tax-deferred can roll over (or make a direct transfer of) their
distribution to a Rollover IRA. These accounts can also receive rollovers or
transfers from an existing IRA. If an "eligible rollover distribution" from a
qualified employer-sponsored retirement plan is not directly rolled over to an
IRA (or certain qualified plans), withholding at the rate of 20% will be
required for federal income tax purposes. A distribution from a qualified plan
that is not an "eligible rollover distribution," including a distribution that
is one of a series of substantially equal periodic payments, generally is
subject to regular wage withholding or withholding at the rate of 10% (depending
on the type and amount of the distribution), unless you elect not to have any
withholding apply. Please consult your tax adviser for more information.

                             GT GLOBAL DOLLAR FUND
 
SEP-IRAS: Simplified employee pension plans ("SEPs" or "SEP-IRAs") provide
self-employed individuals (and any eligible employees) with benefits similar to
Keogh plans (I.E., self-employed individual retirement plans) or Code Section
401(k) plans, but with fewer administrative requirements and therefore
potentially lower annual administration expenses.
 
CODE SECTION 403(B)(7) CUSTODIAL ACCOUNTS: Employees of public schools and most
other tax-exempt organizations can make pre-tax salary reduction contributions
to these accounts.
 
PROFIT-SHARING (INCLUDING SECTION 401(K)) AND MONEY PURCHASE PENSION
PLANS: Corporations and other employers can sponsor these qualified defined
contribution plans for their employees. A Section 401(k) plan, a type of
profit-sharing plan, additionally permits the eligible, participating employees
to make pre-tax salary reduction contributions to the plan (up to certain
limits).
 
SIMPLE PLANS: Employers with no more than 100 employees that do not maintain
another retirement plan may establish a Savings Incentive Match Plan for
Employees ("SIMPLE") either as separate IRAs or as part of a Section 401(k)
plan. SIMPLEs are not subject to the complicated nondiscrimination rules that
generally apply to qualified retirement plans.
 
EXCHANGES BETWEEN FUNDS
   
A shareholder may exchange shares of the Fund for shares of the corresponding
class of other GT Global Mutual Funds or Class A shares of funds of The AIM
Family of Funds-Registered Trademark- as described in the Prospectus. For Class
A shares, a sales load will apply to exchanges from the Fund into other GT
Global Mutual Funds or funds of The AIM Family of Funds, except that no sales
load will be charged if the exchanged shares were acquired as a result of a
previous exchange from another GT Global Mutual Fund. No sales load will be
imposed on the exchange of Class B shares from the Fund into other GT Global
Mutual Funds. The exchange privilege is not an option or right to purchase
shares but is permitted under the current policies of the respective GT Global
Mutual Funds and The AIM Family of Funds. The privilege may be discontinued or
changed at any time by any of those funds upon sixty days' written notice to the
shareholders of the fund and is available only in states where the exchange may
be made legally. Before purchasing shares through the exercise of the exchange
privilege, a shareholder should obtain and read a copy of the prospectus of the
fund to be purchased and should consider its investment objective(s).

SALES CHARGE WAIVERS FOR SHARES PURCHASED PRIOR TO JUNE 1, 1998
    
   
Class B shares purchased before June 1, 1998 are subject to the following
waivers from the contingent deferred sales charge otherwise due upon redemption
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 a GT Global 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 the 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 GT Global
Mutual 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 GT Global Mutual 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

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.
    
 
TELEPHONE REDEMPTIONS
A corporation or partnership wishing to utilize the telephone redemption
services must submit a "Corporate Resolution" or "Certificate of Partnership"
indicating the names, titles and the required number of signatures of persons
authorized to act on its behalf. The certificate must be signed by a duly
authorized officer(s) and, in the case of a corporation, the

<PAGE>
                             GT GLOBAL DOLLAR FUND
corporate seal must be affixed. All shareholders may request that redemption
proceeds be transmitted by bank wire upon request directly to the shareholder's
predesignated account at a domestic bank or savings institution if the proceeds
are at least $500. Costs in connection with the administration of this service,
including wire charges, currently are borne by the appropriate Fund. Proceeds of
less than $500 will be mailed to the shareholder's registered address of record.
The Fund and the Transfer Agent reserve the right to refuse any telephone
instructions and may discontinue the aforementioned redemption options upon
fifteen days' written notice.
 
SUSPENSION OF REDEMPTION PRIVILEGES
The Fund may suspend redemption privileges or postpone the date of payment for
more than seven days after a redemption order is received during any period: (1)
when the NYSE is closed other than customary weekend and holiday closings, or
trading on the NYSE is restricted as directed by the SEC, (2) when an emergency
exists, as defined by the SEC, that would prohibit the Fund from disposing of
portfolio securities owned by them or in fairly determining the value of its
assets, or (3) as the SEC may otherwise permit.
 
SYSTEMATIC WITHDRAWAL PLAN
Shareholders owning Class A or Class B shares of the Fund with a value of
$10,000 or more may establish a Systematic Withdrawal Plan ("SWP"). Under a SWP,
a shareholder will receive monthly or quarterly payments, in amounts of not less
than $100 per payment, through the automatic redemption of the necessary number
of shares on the designated dates (monthly on the 25th day or quarterly on the
25th day of the month the investor first selects). In the event that the 25th
day falls on a Saturday, Sunday or holiday, the redemption will take place on
the prior business day. Certificates, if any, for the shares being redeemed must
be held by the Transfer Agent. Checks will be made payable to the designated
recipient and mailed within seven days. If the recipient is other than the
registered shareholder, the signature of each shareholder must be guaranteed on
the SWP application (see "How to Redeem Shares" in the Prospectus). A
corporation (or partnership) must also submit a "Corporation Resolution" or
"Certificate of Partnership" indicating the names, titles, and signatures of the
individuals authorized to act on its behalf, and the SWP application must be
signed by a duly authorized officer(s) and the corporate seal affixed.
 
Shareholders should be aware that systematic withdrawals may deplete or use up
entirely the initial investment and result in realized long-term or short-term
capital gains or losses. The SWP may be terminated at any time by the Transfer
Agent or the Fund upon 30 days' written notice to shareholders or by a
shareholder upon written notice to the Transfer Agent. Applications and further
details regarding establishment of a SWP are provided at the back of the Fund's
Prospectus.
 
With respect to a SWP established in Class B shares, the maximum annual SWP
withdrawal is 12% of the initial account value. Withdrawals in excess of 12% of
the initial account value annually may result in assessment of a contingent
deferred sales charge.
 
REDEMPTIONS IN KIND
It is possible that conditions may arise in the future which, in the opinion of
the Board, would make it undesirable for the Fund to pay for all redemptions in
cash. In such cases, the Board may authorize payment to be made in portfolio
securities or other property of the Fund, so called "redemptions in kind."
Payment of redemptions in kind will be made in readily marketable securities.
Such securities would be valued at the same value assigned to them in computing
the net asset value per share. Shareholders receiving such securities would
incur brokerage costs in selling any such securities so received.

As described in the Prospectus, the Fund's net asset value per share for each
class of shares is determined each Business Day as of the close of regular
trading on the NYSE (currently, 4:00 p.m. Eastern Time, unless weather,
equipment failure or other factors contribute to an earlier closing time).
Currently, the NYSE is closed on weekends and on certain days relating to the
following holidays: New Year's Day, Martin Luther King Day, President's Day,
Good Friday, Memorial Day, July 4th, Labor Day, Thanksgiving Day and Christmas
Day.

                             GT GLOBAL DOLLAR FUND
 
The net asset value of the Fund's shares is determined by dividing its total
assets less its liabilities by the number of shares outstanding. The Fund may
declare a suspension of the determination of net asset value during the periods
when it may suspend redemption privileges, as provided in "Suspension of
Redemption Privileges," above.
 
The Fund has adopted a policy which requires that it use its best efforts, under
normal circumstances, to maintain a constant net asset value of $1.00 per share.
The Fund values its portfolio securities using the amortized cost method. This
policy does not establish a net asset value of $1.00 per share; it merely
permits a pricing method under which the Fund may seek to maintain a per share
net asset value of $1.00. There can be no assurance that the Fund will be able
to maintain a stable net asset value of $1.00 per share for purchases and
redemptions. The amortized cost method involves valuing a security at its cost
and thereafter accruing any discount or premium at a constant rate to maturity.
By declaring these accruals to the Fund's shareholders in the daily dividend,
the value of the Fund's assets, and, thus, its net asset value per share,
generally will remain constant. Although this method provides certainty in
valuation, it may result in periods during which the value of the Fund's
securities, as determined by amortized cost, is higher or lower than the price
the Fund would receive if it sold the securities. During periods of declining
interest rates, the daily yield on shares of the Fund computed as described
above may tend to be higher than a like computation made by a similar fund with
identical investments utilizing a method of valuation based upon market prices
and estimates of market prices for all of its portfolio securities. Thus, if the
Fund's use of amortized cost resulted in a lower aggregate portfolio value on a
particular day, a prospective investor in the Fund would be able to obtain a
somewhat higher yield than would result from investment in a similar fund
utilizing solely market values, and existing investors in the Fund would receive
less investment income. The converse would apply in a period of rising interest
rates.
 
In connection with the Fund's policy of valuing its securities using the
amortized cost method, the Fund maintains a dollar-weighted portfolio maturity
of 90 days or less and purchases only portfolio securities having remaining
maturities of 13 months or less. The Board also has established procedures in
accordance with Rule 2a-7 under the 1940 Act designed to stabilize, to the
extent reasonably possible, the Fund's net asset value per share, as computed
for the purpose of sales and redemptions, at $1.00. Such procedures include
review of portfolio holdings by the Board, at such intervals as it may deem
appropriate, to determine whether the Fund's net asset value calculated by using
available market quotations deviates from $1.00 per share and, if so, whether
such deviation may result in material dilution or may be otherwise unfair to
existing shareholders. In the event the Board determines that such a deviation
exists, the Board has agreed to take such corrective action as it deems
necessary and appropriate, which action might include selling portfolio
securities prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity, withholding dividends, or paying distributions from
capital or capital gains, redeeming shares in kind, or establishing a net asset
value per share by using available market quotations or market equivalents.

                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject to policies established by the Board, the Sub-adviser is responsible for
the execution of the Fund's portfolio transactions and the selection of
broker/dealers who execute such transactions on behalf of the Fund. Purchases
and sales of money market instruments by the Fund generally are made on a
principal basis, in which the dealer through whom the trade is executed retains
a "spread" as compensation. The spread is the difference in the price at which
the dealer buys or sells the instrument to the Fund and the price which the
dealer is able to resell or at which the dealer originally purchased,
respectively, the instrument. In executing transactions, the Sub-adviser seeks
the best net results for the Fund, taking into account such factors as the price
(including the applicable dealer spread), size of the order, difficulty of
execution and operational facilities of the firm involved. Although the
Sub-adviser generally seeks reasonably competitive spreads, payment of the
lowest spread is not necessarily consistent with the best net results. The Fund
has no obligation to deal with any broker/dealer or group of broker/dealers in
the execution of portfolio transactions.
    
 
   
Investment decisions for the 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 Fund. 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 Fund is concerned, in other cases the Sub-adviser
believes that coordination and the ability to participate in volume transactions
will be beneficial to the Fund.
    
 
   
Under a policy adopted by the Board, 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 Fund and the other funds for which the Sub-adviser serves as
investment manager and/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 Fund and such other funds.

The Fund may, from time to time, provide yield information or comparisons of its
yield to various averages including data from Lipper Analytical Services, Inc.,
Bank Rate Monitor-TM-, IBC/Donaghue's Money Fund Report, MONEY Magazine, and
other industry publications, in advertisements or in reports furnished to
current or prospective shareholders.
 
The Fund calculates its yield for its shares daily, based upon the seven days
ending on the day of the calculation, called the "base period." The yield is
computed by determining the net change in the value of a hypothetical account
with a balance of one share at the beginning of the base period, with the net
change, excluding capital changes, but including the value of any additional
shares purchased with dividends earned from the original one share and all
dividends declared on the original and any purchased shares; dividing the net
change in the account's value by the value of the account at the beginning of
the base period to determine the base period return; and multiplying the base
period return by (365/7). The Fund's effective yield is computed by compounding
the unannualized base period return by adding 1 to the base period return;
raising the sum to the 365/7th power; and subtracting 1 from the result.
 
For the seven-day period ended December 31, 1997, the Fund's Class A share yield
was 4.55% and effective yield was 4.66%. The seven-day and effective yields are
calculated as follows:

The Fund's investment results may also be calculated for longer periods in
accordance with the following method: by subtracting (a) the net asset value of
one share at the beginning of the period, from (b) the net asset value of all
shares an investor would own at the end of the period for the share held at the
beginning of the period (assuming reinvestment of all dividends and
distributions) and dividing by (c) the net asset value per share at the
beginning of the period. The resulting percentage indicates the positive or
negative rate of return that an investor would have earned from the reinvested
dividends and distributions and any changes in share price during the period.
 
The Fund's "Standardized Return," as referred to in the Prospectus (see "Other
Information -- Performance Information" in the Prospectus), is calculated as
follows: Standardized Return ("T") is computed by using the value at the end of
the period ("EV") of a hypothetical initial investment of $1,000 ("P") over a
period of years ("n") according to the following formula as required by the SEC:
P(1+T) to the (n)th power = EV. The following assumptions will be reflected in
computations made in accordance with this formula: (1) for Class B shares,
deduction of the applicable contingent deferred sales charge imposed on a
redemption of Class B shares held for the period; (2) reinvestment of dividends
and other distributions at net asset value on the reinvestment date determined
by the Board; and (3) a complete redemption at the end of any period illustrated
subject to deduction of the applicable contingent deferred sales charge imposed
on a redemption of Class B shares held for the period illustrated.

"Non-Standardized Return," as referred to in the Prospectus, is calculated for a
specified period of time by assuming the investment of $1,000 in Fund shares and
further assuming the reinvestment of all dividends and other distributions made
to Fund shareholders in additional Fund shares at their net asset value.
Percentage rates of return are then calculated by comparing this assumed initial
investment to the value of the hypothetical account at the end of the period for
which the Non-Standardized Return is quoted. As discussed in the Prospectus, the
Fund may quote Non-Standardized Returns that do not reflect the effect of
contingent deferred sales charges. Non-Standardized Returns may be quoted from
the same or different time periods for which Standardized Returns are quoted.

The Fund's investment results will vary from time to time depending upon market
conditions, the composition of the Fund's portfolio and operating expenses of
the Fund, so that current or past yield or total return figures should not be
considered representative of what an investment in the 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 the Fund's
investment results with those published for other investment companies and other
investment vehicles. Investment results also should be considered relative to
the risks associated with the investment objective and policies. The Fund's
investment results will be calculated separately for Class A and Class B shares.
The Fund will include performance data for both Class A and Class B shares of
the Fund in any advertisement or information including performance data for the
Fund.
 
IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKETS
   
The Fund and AIM Distributors may from time to time, in advertisements, sales
literature and reports furnished to present or prospective shareholders, compare
the Fund with the following, among others:
    
 
        (1) The Salomon Brothers Non-U.S. Dollars Indices, which are measures of
    the total return performance of high quality non-U.S. dollar denominated
    securities in major sectors of the worldwide bond markets.
 
        (2) The Lehman Brothers Government/Corporate Bond Index, which is a
    comprehensive measure of all public obligations of the U.S. Treasury
    (excluding flower bonds and foreign targeted issues), all publicly issued
    debt of agencies of the U.S. Government (excluding mortgage backed
    securities), and all public, fixed rate, non-convertible investment grade
    domestic corporate debt rated at least Baa by Moody's Investors Service,
    Inc. ("Moody's") or BBB by Standard and Poor's Ratings Group ("S&P"), or, in
    the case of nonrated bonds, BBB by Fitch Investors Service ("Fitch")
    (excluding Collateralized Mortgage Obligations).
 
   
        (3) Average of savings accounts, which is a measure of all kinds of
    savings deposits, including longer-term certificates (based on figures
    supplied by the U.S. League of Savings Institutions). Savings accounts offer
    a guaranteed rate of return on principal, but no opportunity for capital
    growth. The maximum rates paid on some savings deposits are currently fixed
    by law.
    
 
        (4) The Consumer Price Index ("CPI"), which is a measure of the average
    change in prices over time in a fixed market basket of goods and services
    (e.g., food, clothing, shelter, fuels, transportation fares, charges for
    doctors' and dentists' services, prescription medicines, and other goods and
    services that people buy for day-to-day living). There is inflation risk
    which does not affect a security's value but its purchasing power, i.e., the
    risk of changing price levels in the economy that affects security prices or
    the price of goods and services.
 
        (5) Data and mutual fund rankings published or prepared by Lipper
    Analytical Data Services, Inc. ("Lipper"), CDA/Wiesenberger Investment
    Company Service ("CDA/Wiesenberger"), Morningstar, Inc. ("Morningstar"),
    Micropal, Inc. and/or other companies that rank and/or compare mutual funds
    by overall performance, investment objectives, assets, expense levels,
    periods of existence and/or other factors. In this regard the Fund may be
    compared to its "peer group" as defined by Lipper, CDA/Wiesenberger,
    Morningstar and/or other firms, as applicable, or to specific funds or
    groups of funds within or outside of such peer group. Lipper generally ranks
    funds on the basis of total return, assuming reinvestment of distributions,
    but does not take sales charges or redemption fees into consideration, and
    is prepared without regard to tax consequences. In addition to the mutual
    fund rankings, the Fund's performance may be compared to mutual fund
    performance indices prepared by Lipper. Morningstar is a mutual fund rating
    service that also rates mutual funds on the basis of risk-adjusted
    performance. Morningstar ratings are calculated from a fund's three, five
    and ten year average annual returns with appropriate fee adjustments and a
    risk factor that reflects fund performance relative to the three-month U.S.
    Treasury bill monthly returns. Ten percent of the funds in an investment
    category receive five stars and 22.5% receive four stars. The ratings are
    subject to change each month.

        (6) Bear Stearns Foreign Bond Index, which provides simple average
    returns for individual countries and gross national product ("GNP")-weighted
    index, beginning in 1975. The returns are broken down by local market and
    currency.
 
        (7) Ibbotson Associates International Bond Index, which provides a
    detailed breakdown of local market and currency returns since 1960.
 
        (8) Salomon Brothers Broad Investment Grade Index, which is a widely
    used index composed of U.S. domestic government, corporate and
    mortgage-backed fixed income securities.
 
        (9) Salomon Brothers World Government Bond Index and Salomon Brothers
    World Government Bond Index-Non-U.S., each of which is a widely used index
    composed of world government bonds.
 
       (10) The World Bank Publication of Trends in Developing Countries
    ("TIDE"), which provides brief reports on most of the World Bank's borrowing
    members. The World Development Report is published annually and looks at
    global and regional economic trends and their implications for the
    developing economies.
 
       (11) Datastream and Worldscope, each of which is an on-line database
    retrieval service for information, including international financial and
    economic data.
 
       (12) International Financial Statistics, which is produced by the
    International Monetary Fund.
 
       (13) Various publications and reports produced by the World Bank and its
    affiliates.
 
       (14) Various publications from the International Bank for Reconstruction
    and Development.
 
       (15) Various publications produced by ratings agencies such as Moody's,
    S&P and Fitch.
 
       (16) Privatizations from various sources, stock market capitalization,
    number of issuers, and trading volume of newly privatized companies and, in
    addition, projected levels of privatization. Privatization, an economic
    process virtually unknown in the U.S., is the selling of state-owned
    companies to the private sector. Under private ownership, such companies can
    release assets and seek to make profits free from political intervention.
    Examples of state-owned industries being privatized outside the U.S. include
    airlines, telecommunications, utilities and financial institutions.
 
   
Indices, economic and financial data prepared by the research departments of
various financial organizations, such as Salomon Brothers, Inc., Lehman
Brothers, Merrill Lynch, Pierce, Fenner & Smith, Inc., Financial Research
Corporation, J. P. Morgan, Morgan Stanley, Smith Barney Shearson, S.G. Warburg,
Jardine Flemming, The Bank for International Settlements, Asian Development
Bank, Bloomberg, L.P. and Ibbotson Associates, may be used, as well as
information reported by the Federal Reserve and the respective central banks of
various nations. In addition, AIM Distributors may use performance rankings,
ratings and commentary reported periodically in national financial publications,
including Money Magazine, Mutual Fund Magazine, Smart Money, Global Finance,
EuroMoney, Financial World, Forbes, Fortune, Business Week, Latin Finance, the
Wall Street Journal, Emerging Markets Weekly, Kiplinger's Guide To Personal
Finance, Barron's, The Financial Times, USA Today, The New York Times, Far
Eastern Economic Review, The Economist and Investors Business Digest. Each Fund
may compare its performance to that of other compilations or indices of
comparable quality to those listed above and other indices that may be developed
and made available in the future.
    
 
The Fund may compare its performance to that of other compilations or indices of
comparable quality to those listed above which may be developed and made
available in the future. The Fund may be compared in advertising to Certificates
of Deposit (CDs), the Bank Rate Monitor National Index, an average of the quoted
rates for 100 leading banks and thrifts in ten U.S. cities chosen to represent
the ten largest Consumer Metropolitan statistical areas, or other investments
issued by banks. The Fund differs from bank investments in several respects. The
Fund may offer greater liquidity or higher potential returns than CDs; but
unlike CDs, the Fund will have a fluctuating share price and return and is not
FDIC insured.
 
   
AIM Distributors may provide information designed to help individuals understand
their investment goals and explore various financial strategies. For example,
AIM Distributors may describe general principles of investing, such as asset
allocation, diversification and risk tolerance.
    
 
   
In advertising and sales materials, AIM Distributors may make reference to or
discuss its products and services, which may include: retirement investing; the
effects of dollar-cost averaging and saving for college or a home. In addition,
AIM Distributors may quote financial or business publications and periodicals,
including model portfolios or allocations, as they relate to fund management,
investment philosophy, and investment techniques.

                             GT GLOBAL DOLLAR FUND
 
The Fund may quote various measures of volatility and benchmark correlation such
as beta, standard deviation and R(2) in advertising. In addition, the Fund may
compare these measures to those of other funds. Measures of volatility seek to
compare the Fund's total returns compared to those of a benchmark. All measures
of volatility and correlation are calculated using averages of historical data.
 
The Fund may advertise examples of the effects of periodic investment plans,
including the principle of dollar cost averaging. In such a program, an investor
invests a fixed dollar amount in a fund at periodic intervals, thereby
purchasing fewer shares when prices are high and more shares when prices are
low. While such a strategy does not assure a profit or guard against loss in a
declining market, the investor's average cost per share can be lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating such
a plan, investors should consider their ability to continue purchasing shares
through periods of low price levels.
 
The Fund may describe in its sales material and advertisements how an investor
may invest in the GT Global Mutual Funds through various retirement plans or
other programs that offer deferral of income taxes on investment earnings and
pursuant to which an investor may make deductible contributions. Because of
their advantages, these retirement plans and programs may produce returns
superior to comparable non-retirement investments. For example, a $10,000
investment earning a taxable return of 10% annually would have an after-tax
value of $17,976 after ten years, assuming tax was deducted from the return each
year at a 39.6% rate. An equivalent tax-deferred investment would have an
after-tax value of $19,626 after ten years, assuming tax was deducted at a 39.6%
rate from the deferred earnings at the end of the ten-year period. In sales
material and advertisements, the Fund may also discuss these plans and programs.
See "Information Relating to Sales and Redemptions -- Individual Retirement
Accounts ('IRAs') and Other Tax-Deferred Plans."
 
   
In advertising and sales materials, AIM Distributors may make reference to or
discuss its products, services and accomplishments. Among these accomplishments
are that in 1983 the Sub-Adviser provided assistance to the government of Hong
Kong in linking its currency to the U.S. dollar, and that in 1987 Japan's
Ministry of Finance licensed LGT Asset Management Ltd. as one of the first
foreign discretionary investment managers for Japanese investors. Such
accomplishments, however, should not be viewed as an endorsement of the
Sub-adviser by the government of Hong Kong, Japan's Ministry of Finance or any
other government or government agency. Nor do any such accomplishments of the
Sub-adviser provide any assurance that the GT Global Mutual Funds' investment
objectives will be achieved.
    
 
   
[THE GT ADVANTAGE

of service to individuals and institutions. Today we bring investors a

talent and a time-tested investment discipline. With investment professionals in

firsthand. Many of the GT Global Mutual Funds' portfolio managers are natives of
the countries in which they invest, speak local languages and/or live or work in
the markets they follow.
 
The key to achieving consistent results is following a disciplined investment
process. Our approach to asset allocation takes advantage of GT Global's
worldwide presence and global perspective. Our "macroeconomic" worldview
determines our overall strategy of regional, country and sector allocations. Our
bottom-up process of security selection combines fundamental research with
quantitative analysis through our proprietary models.

experience and judgment with an objective assessment of risk. Ultimately, each
security we select has passed a ranking system that helps our portfolio teams
determine when to buy and when to sell.]

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
COMMERCIAL PAPER RATINGS
    S&P. "A-1" and "A-2" are the two highest commercial paper rating categories:
 
        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 are denoted with a plus sign (+) designation.
 
                  Statement of Additional Information Page 22
<PAGE>
                             GT GLOBAL DOLLAR FUND
 
        A-2. Capacity for timely payment on issues with this designation is
    satisfactory. However, the relative degree of safety is not as high as for
    issues designated "A-1".
 
    MOODY'S. "Prime-1" and "Prime-2" are the two highest commercial paper rating
categories.
 
        Prime-1. Issuers (or supporting institutions) assigned this highest
    rating have 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.
 
        Prime-2. Issuers (or supporting institutions) assigned this rating have
    a strong ability for repayment of senior short-term debt obligations. This
    will normally 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.
 
BOND RATINGS
    S&P: Its ratings for high quality bonds are as follows:
 
        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.
 
        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.
 
    MOODY'S: Its ratings for high quality bonds are as follows:
 
        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.
 
        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.
 
NOTE RATINGS
    S&P: The SP-1 rating denotes a very strong or strong capacity to pay
principal and interest. Those issues determined to possess overwhelming safety
characteristics will be given a plus (+) designation.
 
The SP-2 rating denotes a satisfactory capacity to pay principal and interest.
 
    MOODY'S: The MIG 1 designation denotes best quality. There is strong
protection by established cash flows, superior liquidity support or demonstrated
broad-based access to the market for refinancing.
 
The MIG 2 designation denotes high quality. Margins of protection are ample
although not as large as in the preceding group.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVE
The investment objective of the Fund is maximum current income consistent with
liquidity and conservation of capital. The Fund seeks its objective by investing
in high quality, U.S. dollar-denominated money market instruments.
 
CHANGES IN A SECURITY'S RATING
   
Subsequent to the purchase of a security by the Fund, the security may cease to
be rated or its rating may be reduced below the minimum rating required for its
purchase, as described in the Prospectus. In such event the Fund, the Company's
Board of Trustees (the "Board") and the Sub-adviser will review the situation
and take appropriate action in accordance with procedures adopted by the Board
pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended (the
"1940 Act").
    
 
VARIABLE AND FLOATING RATE OBLIGATIONS
Floating and variable rate demand notes and bonds are obligations ordinarily
having stated maturities in excess of 13 months, but which permit the holder to
demand payment of principal at any time, or at specified intervals not exceeding
13 months, in each case upon not more than 30 days' notice. The issuer of such
obligations generally has a corresponding right, after a given period, to prepay
in its discretion the outstanding principal amount of the obligation plus
accrued interest upon a specified number of days' notice to the holders thereof.
The interest rates payable on certain securities in which the Fund may invest
are not fixed and may fluctuate based upon changes in market rates. Variable and
floating rate obligations have interest rates that are adjusted at designated
intervals or whenever there are changes in the market rates of interest on which
the interest rates are based. Variable and floating rate obligations permit the
Fund to "lock in" the current interest rate for only the period until the next
rate adjustment, but the rate adjustment feature tends to limit the extent to
which the market value of the obligation will fluctuate.
 
BANKERS' ACCEPTANCES
Bankers' acceptances are negotiable obligations of a bank to pay a draft which
has been drawn on it by a customer. These obligations are backed by large banks
and usually are backed by goods in international trade.
 
CERTIFICATES OF DEPOSIT
Certificates of deposit are negotiable certificates representing a commercial
bank's obligations to repay funds deposited with it, earning specified rates of
interest over a given period of time.
 
COMMERCIAL PAPER
Commercial paper consists of short-term promissory notes issued by large
corporations with a high quality rating to finance short-term credit needs.
 
U.S. GOVERNMENT OBLIGATIONS
U.S. government obligations are debt securities issued or guaranteed by the U.S.
Treasury or by an agency or instrumentality of the U.S. government. However, not
all U.S. government obligations are backed by the full faith and credit of the
United States. For example, securities issued by the Federal National Mortgage
Association, the Federal Home Loan Mortgage Corporation and the Tennessee Valley
Authority are supported only by the credit of the issuer. There is no guarantee
that the U.S. government will provide support to such U.S. government sponsored
agencies, as it is not so obligated by law. Therefore, the purchase of such
securities involves more risk than investment in other U.S. government
obligations.
 
REPURCHASE AGREEMENTS
   
A repurchase agreement is a transaction in which the Fund purchases a security
from a bank or recognized securities dealer and simultaneously commits to resell
that security to the bank or dealer, an agreed-upon price, date and market rate
of interest unrelated to 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 Fund if the other party to the
repurchase agreement becomes bankrupt, the Fund intends to enter into repurchase
agreements only with banks and dealers believed by the Sub-adviser to present
    
 
                   Statement of Additional Information Page 2
<PAGE>
                             GT GLOBAL DOLLAR FUND
   
minimal credit risks in accordance with guidelines established by the Board. The
Sub-adviser will review and monitor the creditworthiness of such institutions
under the Board's general supervision.
    
 
The Fund 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 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 the 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, the Fund intends to comply with provisions
under that code that would allow the immediate resale of such collateral. There
is no limitation on the amount of the Fund's assets that may be subject to
repurchase agreements at any given time. The 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 its net assets would be invested in such
repurchase agreements and other illiquid investments.
 
WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS
The Fund may buy and sell securities on a when-issued or delayed delivery basis,
with payment and delivery taking place at a future date. The market value of
securities purchased in this way may change before the delivery date, which
could increase fluctuations in the Fund's yield. Ordinarily, the Fund will not
earn interest on securities purchased until they are delivered.
 
ILLIQUID SECURITIES
   
The Fund will not invest more than 10% of its net assets in illiquid securities.
The term "illiquid securities" for this purpose means securities that cannot be
disposed of within seven days in the ordinary course of business at
approximately the amount at which the Fund has valued the securities and
includes, among other things, repurchase agreements maturing in more than seven
days, and restricted securities other than those the Sub-adviser has determined
to be liquid pursuant to guidelines established by the Board. Commercial paper
issues in which the Fund may invest include securities issued by major
corporations without registration under the Securities Act of 1933, as amended
(the "1933 Act"), in reliance on the exemption from such registration afforded
by Section 3(a)(3) thereof and commercial paper issued in reliance on the so-
called "private placement" exemption from registration afforded by Section 4(2)
of the 1933 Act ("Section 4(2) paper"). Section 4(2) paper is restricted as to
disposition under the federal securities laws in that any resale must similarly
be made in an exempt transaction. Section 4(2) paper is normally resold to other
institutional investors through or with the assistance of investment dealers who
make a market in Section 4(2) paper, thus providing liquidity.
    
 
Not all restricted securities are illiquid. In recent years a large
institutional market has developed for certain securities that are not
registered under the 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 on or 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, 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 the 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 Board 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 (1) the frequency of trading in the security; (2)
the number of dealers that make quotes for the security; (3) the number of
dealers that have undertaken to make a market in the security; (4) the number of
other potential purchasers; and (5) the nature of the security and how trading
is effected (E.G., the time needed to sell the security, how offers are
    
 
                   Statement of Additional Information Page 3
<PAGE>
                             GT GLOBAL DOLLAR FUND
   
solicited and the mechanics of transfer). The Sub-adviser monitors the liquidity
of securities held by the Fund and periodically reports such determinations to
the Board as applicable. If the liquidity percentage restriction of the 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
the 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.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
   
The Fund has adopted the following investment limitations as fundamental
policies that may not be changed without approval by the affirmative vote of 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, and (ii) more than 50% of
the Fund's outstanding shares. The Fund may not:
    
 
   
        (1) Purchase securities of any one issuer if, as a result, more than 5%
    of the Fund's total assets would be invested in securities of that issuer or
    the Fund would own or hold more than 10% of the outstanding voting
    securities of that issuer, except that up to 25% of the 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;
    
 
   
        (2) 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;
    
 
   
        (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) 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 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) 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;
    
 
   
        (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; or
    
 
   
        (7) 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;
    
 
   
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.

                             GT GLOBAL DOLLAR FUND
 
   
For purposes of the concentration policy contained in limitation (7), above, the
Fund intends to comply with the Securities and Exchange Commission ("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.
    
 
   
If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values or assets
will not constitute a violation of that restriction.
    
 
   
The following investment policies of the 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) Invest more than 10% of its net assets in illiquid securities;
    
 
   
        (2) 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; 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.

the Sub-adviser. Each Trustee who is not a director, officer or employee of the
Sub-adviser or any affiliated company is paid aggregate fees of $1,000 per
annum, plus $300 for each meeting of the Board or any committee thereof attended
by the Director, 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 Company. For the fiscal year
ended December 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 $3,588, $3,716, $3,100 and
$3,409, respectively, from the Company for their services as Trustees. For the
fiscal year ended December 31, 1997, Mr. Anderson, Mr. Bayley, Mr. Patterson and
Miss Quigley received total compensation of $103,654, $106,556, $89,700 and
$98,038, respectively, from the investment companies managed or administered by
AIM and sub-advised and sub-administered by the Sub-adviser for which he or she
serves as a Trustee. Fees and expenses disbursed to the Trustees contained no
accrued or payable pension or retirement benefits. As of January 8, 1998, the
Trustees and Officers and their families as a group owned in the aggregate
beneficially or of record less than 1% of the outstanding shares of the Fund.

- --------------------------------------------------------------------------------
 
INVESTMENT MANAGEMENT AND ADMINISTRATION SERVICES
   
AIM serves as the Fund's investment manager and administrator under an
Investment Management and Administration Contract between the Company and AIM
("Management Contract"). The Sub-adviser serves as the sub-adviser and sub-
administrator to the 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
Fund and administer the 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 Company and the Fund, and provide suitable office space,
necessary small office equipment and utilities.
    
 
   
The Management Contracts may be renewed for one-year terms with respect to the
Fund, provided that any such renewal has been specifically approved at least
annually by: (i) the Board, or by the vote of a majority of the 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. Either the
Company or each of AIM or the Sub-adviser may terminate the Management 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).
    
 
   
For the fiscal years ended December 31, 1997, 1996 and 1995, the Fund paid
investment management and administration fees to the Sub-adviser in the amounts
of $1,384,735, $1,808,976 and $1,665,299, respectively. During the fiscal years
ended December 31, 1997 and 1996, the Sub-adviser reimbursed the Fund for a
portion of its investment management and administration fees in the amounts of
$88,707 and $173,045, respectively. No such reimbursements were made during the
fiscal year ended December 31, 1995.
    
 
DISTRIBUTION SERVICES
   
The Fund's Advisor Class are offered continuously through the Fund's principal
underwriter and distributor, AIM Distributors, on a "best efforts" basis without
a sales charge or a contingent deferred sales charge.
    
 
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The Transfer Agent has been retained by the Fund to perform shareholder
servicing, reporting and general transfer agent functions for the Fund. For
these services, the Transfer Agent receives an annual maintenance fee of $17.50
per account, a new account fee of $4.00 per account, a per transaction fee of
$1.75 for all transactions other than exchanges and a per exchange fee of $2.25.
The Transfer Agent also is reimbursed by the Fund for its out-of-pocket expenses
for such items as postage, forms, telephone charges, stationery and office
supplies. The Sub-adviser also serves as the Fund's pricing and accounting
agent. For the fiscal years ended December 31, 1997, 1996 and 1995, the
accounting services fees for the Fund were $69,517, $90,682 and $86,710,
respectively.
    
 
EXPENSES OF THE FUND
   
The Fund 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,
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 Company
expenses and expenses shared among the Fund 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 Fund or the nature of the services
performed and relative applicability to the 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.

                              DIVIDENDS AND TAXES
 
- --------------------------------------------------------------------------------
 
DAILY INCOME DIVIDENDS
Net investment income and any realized net short-term capital gain are
determined and declared as a dividend each day. Each such dividend is payable to
shareholders as of the close of business on that day. Orders to purchase Fund
shares are executed on the business day on which Federal Funds, i.e., monies
held on deposit at a Federal Reserve Bank, become available. Shares begin
accruing dividends on the day following the date of purchase. Shares are
entitled to the dividend declared on the day a redemption request is received by
the Transfer Agent. Dividends are automatically reinvested in Advisor Class
shares of the Fund on the last Business Day of the month, at net asset value,
unless a shareholder otherwise instructs the Transfer Agent in writing. A
shareholder that does so will be mailed a check in the amount of each dividend.
For the purpose of calculating dividends, daily net investment income of the
Fund consists of (a) all interest income accrued on investments (including any
discount or premium ratably accrued or amortized, respectively, to the date of
maturity or determined in such other manner the Fund chooses in accordance with
generally accepted accounting principles), (b) minus all accrued liabilities,
including interest, taxes and other expense items, and reserves for contingent
or undetermined liabilities, all determined in accordance with those principles,
(c) plus or minus all realized gains or losses on investments, if any.
 
TAXES -- GENERAL
To continue to qualify for treatment as a regulated investment company under the
Internal Revenue Code of 1986, as amended (the "Code"), the Fund must distribute
to its shareholders for each taxable year at least 90% of its investment company
taxable income (consisting of net investment income and any net short-term
capital gain) 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 and gains from the sale or other
disposition of securities, or other income derived with respect to its business
of investing in securities; and (2) the Fund must diversify its holdings so
that, at the close of each quarter of its taxable year, (i) at least 50% of the
value of its total assets is represented by cash and cash items, U.S. government
securities and other securities limited, with respect to any one issuer, to an
amount that does not exceed 5% of the value of the Fund's total assets and (ii)
not more than 25% of the value of its total assets is invested in the securities
of any one issuer (other than U.S. government securities).
 
The Fund will be subject to a nondeductible 4% 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, if any, for the one-year
period ending on October 31 of that year, plus certain other amounts.
 
Dividends from the Fund's investment company taxable income are taxable to its
shareholders as ordinary income. The Fund does not expect to receive any
dividend income from U.S. corporations, which means that no part of the
dividends from the Fund will be eligible for the dividends-received deduction
allowed to corporations. Dividends will be taxed for federal income tax purposes
in the same manner whether they are received in cash or reinvested in additional
Fund shares.
 
NON-U.S. SHAREHOLDERS
Dividends paid by the 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 (a "foreign shareholder") will be
subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply if a dividend paid by the Fund to a foreign
shareholder 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.
 
The foregoing is a general and abbreviated summary of certain federal tax
considerations affecting the 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 an investment in the
Fund.

                             SALES AND REDEMPTIONS
 
- --------------------------------------------------------------------------------
 
STATEMENTS AND REPORTS
When an investor makes an initial investment in the Fund, a shareholder account
is opened in accordance with the investor's registration instructions.
Shareholders receive monthly statements detailing account transactions. Shortly
after the end of the Fund's fiscal year on December 31 and fiscal half-year on
June 30, shareholders receive an annual and semiannual report, respectively.
These reports list the securities held by the Fund and contain the Fund's
financial statements. In addition, the federal income tax status of dividends
paid by the Fund to shareholders is reported after the end of each calendar year
on Form 1099-DIV.
 
PAYMENT AND TERMS OF OFFERING
Payment for Advisor Class shares should accompany the purchase order, or funds
should be wired to the Transfer Agent as described in the Prospectus. Payment,
other than by wire transfer, must be made by check or money order drawn on a
U.S. bank. Checks or money orders must be payable in U.S. dollars.
 
As a condition of this offering, if an order to purchase either class of shares
is cancelled due to nonpayment (for example, because a check is returned for
insufficient funds), the person who made the order will be responsible for any
loss incurred by the Fund by reason of such cancellation, and if such purchaser
is a shareholder, the Fund shall have the authority as agent of the shareholder
to redeem shares in his or her account for their then-current net asset value
per share to reimburse the Company for the loss incurred. Investors whose
purchase orders have been cancelled due to nonpayment may be prohibited from
placing future orders.
 
The Fund reserves the right at any time to waive or increase the minimum
requirements applicable to initial or subsequent investments with respect to any
person or class of persons. An order to purchase shares is not binding on the
Fund until it has been confirmed in writing by the Transfer Agent (or other
arrangements made with the Fund, in the case of orders utilizing wire transfer
of funds, as described above) and payment has been received. To protect existing
shareholders, the Fund reserves the right to reject any offer for a purchase of
shares by any individual.
 
WHEN ORDERS ARE EFFECTIVE
In order to maximize earnings on its portfolio, the Fund intends at all times to
be as completely invested as reasonably possible. Transactions in the money
market instruments in which the Fund invests normally require immediate
settlement in Federal Funds, as defined above. Thus, an order to purchase Fund
shares will be executed on any day Monday through Friday on which the New York
Stock Exchange ("NYSE") is open for business ("Business Day"), on which Federal
Funds become available to the Fund. Funds transmitted by bank wire to the
Transfer Agent and received by it prior to the close of regular trading on the
NYSE will normally be credited to a shareholder's account on the same day as
received. Funds transmitted by bank wire and received after the close of regular
trading on the NYSE normally will be credited on the next Business Day. If
remitted in other than the foregoing manner, such as by check, purchase orders
will be executed as of the close of business on the day on which the payment is
converted into Federal Funds, normally two days after receipt of the payment.
The investor becomes a shareholder on the day on which the order is effective.
Dividends begin to accrue on the next day. Information on how to transmit
Federal Funds by wire is available at any national bank or any state bank which
is a member of the Federal Reserve System. Any such bank may charge the
shareholder for this service.
 
INDIVIDUAL RETIREMENT ACCOUNTS ("IRAS") AND OTHER TAX-DEFERRED PLANS
 
   
IRAS: If you have earned income from employment (including self-employment), you
can contribute each year to an IRA up to the lesser of (1) $2,000 for yourself
or $4,000 for you and your spouse, regardless of whether your spouse is
employed, or (2) 100% of compensation. Some individuals may be able to take an
income tax deduction for the contribution. Regular contributions may not be made
for the year you become 70 1/2 or thereafter. Unless your and your spouse's
earnings exceed a certain level, you also may establish an "education IRA"
and/or a "Roth IRA." Although contributions to these new types of IRAs are
nondeductible, withdrawals from them will be tax-free under certain
circumstances. Please consult your tax adviser for more information. IRA
applications are available from brokers or AIM Distributors.
    
 
ROLLOVER IRAS: Individuals who receive distributions from qualified retirement
plans (other than required distributions) and who wish to keep their savings
growing tax-deferred can roll over (or make a direct transfer of) their
distribution to a Rollover IRA. These accounts can also receive rollovers or
transfers from an existing IRA. If an "eligible rollover
 
                  Statement of Additional Information Page 10
<PAGE>
                             GT GLOBAL DOLLAR FUND
distribution" from a qualified employer-sponsored retirement plan is not
directly rolled over to an IRA (or certain qualified plans), withholding at the
rate of 20% will be required for federal income tax purposes. A distribution
from a qualified plan that is not an "eligible rollover distribution," including
a distribution that is one of a series of substantially equal periodic payments,
generally is subject to regular wage withholding or withholding at the rate of
10% (depending on the type and amount of the distribution), unless you elect not
to have any withholding apply. Please consult your tax adviser for more
information.
 
SEP-IRAS: Simplified employee pension plans ("SEPs" or "SEP-IRAs") provide
self-employed individuals (and any eligible employees) with benefits similar to
Keogh plans (I.E., self-employed individual retirement plans) or Code Section
401(k) plans, but with fewer administrative requirements and therefore
potentially lower annual administration expenses.
 
CODE SECTION 403(b)(7) CUSTODIAL ACCOUNTS: Employees of public schools and most
other tax-exempt organizations can make pre-tax salary reduction contributions
to these accounts.
 
PROFIT-SHARING (INCLUDING SECTION 401(K)) AND MONEY PURCHASE PENSION
PLANS: Corporations and other employers can sponsor these qualified defined
contribution plans for their employees. A Section 401(k) plan, a type of
profit-sharing plan, additionally permits the eligible, participating employees
to make pre-tax salary reduction contributions to the plan (up to certain
limits).
 
SIMPLE PLANS: Employers with no more than 100 employees that do not maintain
another retirement plan may establish a Savings Incentive Match Plan for
Employees ("SIMPLE") either as separate IRAs or as part of a Section 401(k)
plan. SIMPLEs are not subject to the complicated nondiscrimination rules that
generally apply to qualified retirement plans.
 
EXCHANGES BETWEEN FUNDS
A shareholder may exchange shares of the Fund for shares of the corresponding
class of other GT Global Mutual Funds as described in the Prospectus. Advisor
Class shares may be exchanged only for Advisor Class shares of other GT Global
Mutual Funds. The exchange privilege is not an option or right to purchase
shares but is permitted under the current policies of the respective, GT Global
Mutual Funds. The privilege may be discontinued or changed at any time by any of
those funds upon sixty days' written notice to the shareholders of the fund and
is available only in states where the exchange may be made legally. Before
purchasing shares through the exercise of the exchange privilege, a shareholder
should obtain and read a copy of the prospectus of the fund to be purchased and
should consider its investment objective(s).
 
TELEPHONE REDEMPTIONS
A corporation or partnership wishing to utilize the telephone redemption
services must submit a "Corporate Resolution" or "Certificate of Partnership"
indicating the names, titles and the required number of signatures of persons
authorized to act on its behalf. The certificate must be signed by a duly
authorized officer(s) and, in the case of a corporation, the corporate seal must
be affixed. All shareholders may request that redemption proceeds be transmitted
by bank wire upon request directly to the shareholder's predesignated account at
a domestic bank or savings institution if the proceeds are at least $1,000.
Costs in connection with the administration of this service, including wire
charges, currently are borne by the appropriate Fund. Proceeds of less than
$1,000 will be mailed to the shareholder's registered address of record. The
Fund and the Transfer Agent reserve the right to refuse any telephone
instructions and may discontinue the aforementioned redemption options upon
thirty days' written notice.
 
SUSPENSION OF REDEMPTION PRIVILEGES
The Fund may suspend redemption privileges or postpone the date of payment for
more than seven days after a redemption order is received during any period: (1)
when the NYSE is closed other than customary weekend and holiday closings, or
trading on the NYSE is restricted as directed by the SEC, (2) when an emergency
exists, as defined by the SEC, that would prohibit the Fund from disposing of
portfolio securities owned by them or in fairly determining the value of its
assets, or (3) as the SEC may otherwise permit.
 
REDEMPTIONS IN KIND
It is possible that conditions may arise in the future which, in the opinion of
the Board, would make it undesirable for the Fund to pay for all redemptions in
cash. In such cases, the Board may authorize payment to be made in portfolio
securities or other property of the Fund, so called "Redemptions in Kind."
Payment of redemptions in kind will be made in readily marketable securities.
Such securities would be valued at the same value assigned to them in computing
the net asset value per share. Shareholders receiving such securities would
incur brokerage costs in selling any such securities so received.

                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
 
As described in the Prospectus, the Fund's net asset value per share for each
class of shares is determined each Business Day as of the close of regular
trading on the NYSE (currently, 4:00 p.m. Eastern Time, unless weather,
equipment failure or other factors contribute to an earlier closing time).
Currently, the NYSE is closed on weekends and on certain days relating to the
following holidays: New Year's Day, Martin Luther King Day, President's Day,
Good Friday, Memorial Day, July 4th, Labor Day, Thanksgiving Day and Christmas
Day.
 
The net asset value of the Fund's shares is determined by dividing its total
assets less its liabilities by the number of shares outstanding. The Fund may
declare a suspension of the determination of net asset value during the periods
when it may suspend redemption privileges, as provided in "Suspension of
Redemption Privileges," above.
 
The Fund has adopted a policy which requires that it use its best efforts, under
normal circumstances, to maintain a constant net asset value of $1.00 per share.
The Fund values its portfolio securities using the amortized cost method. This
policy does not establish a net asset value of $1.00 per share; it merely
permits a pricing method under which the Fund may seek to maintain a per share
net asset value of $1.00. There can be no assurance that the Fund will be able
to maintain a stable net asset value of $1.00 per share for purchases and
redemptions. The amortized cost method involves valuing a security at its cost
and thereafter accruing any discount or premium at a constant rate to maturity.
By declaring these accruals to the Fund's shareholders in the daily dividend,
the value of the Fund's assets, and, thus, its net asset value per share,
generally will remain constant. Although this method provides certainty in
valuation, it may result in periods during which the value of the Fund's
securities, as determined by amortized cost, is higher or lower than the price
the Fund would receive if it sold the securities. During periods of declining
interest rates, the daily yield on shares of the Fund computed as described
above may tend to be higher than a like computation made by a similar fund with
identical investments utilizing a method of valuation based upon market prices
and estimates of market prices for all of its portfolio securities. Thus, if the
Fund's use of amortized cost resulted in a lower aggregate portfolio value on a
particular day, a prospective investor in the Fund would be able to obtain a
somewhat higher yield than would result from investment in a similar fund
utilizing solely market values, and existing investors in the Fund would receive
less investment income. The converse would apply in a period of rising interest
rates.
 
In connection with the Fund's policy of valuing its securities using the
amortized cost method, the Fund maintains a dollar-weighted portfolio maturity
of 90 days or less and purchases only portfolio securities having remaining
maturities of 13 months or less. The Board also has established procedures in
accordance with Rule 2a-7 under the 1940 Act designed to stabilize, to the
extent reasonably possible, the Fund's net asset value per share, as computed
for the purpose of sales and redemptions, at $1.00. Such procedures include
review of portfolio holdings by the Board, at such intervals as it may deem
appropriate, to determine whether the Fund's net asset value calculated by using
available market quotations deviates from $1.00 per share and, if so, whether
such deviation may result in material dilution or may be otherwise unfair to
existing shareholders. In the event the Board determines that such a deviation
exists, the Board has agreed to take such corrective action as it deems
necessary and appropriate, which action might include selling portfolio
securities prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity, withholding dividends, or paying distributions from
capital or capital gains, redeeming shares in kind, or establishing a net asset
value per share by using available market quotations or market equivalents.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject to policies established by the Board, the Sub-adviser is responsible for
the execution of the Fund's portfolio transactions and the selection of
broker/dealers who execute such transactions on behalf of the Fund. Purchases
and sales of money market instruments by the Fund generally are made on a
principal basis, in which the dealer through whom the trade is executed retains
a "spread" as compensation. The spread is the difference in the price at which
the dealer buys or sells the instrument to the Fund and the price which the
dealer is able to resell or at which the dealer originally purchased,
respectively, the instrument. In executing transactions, the Sub-adviser seeks
the best net results for the Fund, taking into account such factors as the price
(including the applicable dealer spread), size of the order, difficulty of
execution and operational facilities of the firm involved. Although the
Sub-adviser generally seeks reasonably competitive spreads, payment of the
lowest spread is not necessarily consistent with the best net results. The Fund
has no obligation to deal with any broker/dealer or group of broker/dealers in
the execution of portfolio transactions.
    
 
   
Investment decisions for the 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 Fund. 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 Fund is concerned, in other cases the Sub-adviser
believes that coordination and the ability to participate in volume transactions
will be beneficial to the Fund.
    
 
   
Under a policy adopted by the Board 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 Fund and the other funds for which the Sub-adviser serves as
investment manager and/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 Fund and such other funds.

The Fund may, from time to time, provide yield information or comparisons of its
yield to various averages including data from Lipper Analytical Services, Inc.,
Bank Rate Monitor-TM-, IBC/Donaghue's Money Fund Report, MONEY Magazine, and
other industry publications, in advertisements or in reports furnished to
current or prospective shareholders.
 
The Fund calculates its yield for its shares daily, based upon the seven days
ending on the day of the calculation, called the "base period." The yield is
computed by determining the net change in the value of a hypothetical account
with a balance of one share at the beginning of the base period, with the net
change, excluding capital changes, but including the value of any additional
shares purchased with dividends earned from the original one share and all
dividends declared on the original and any purchased shares; dividing the net
change in the account's value by the value of the account at the beginning of
the base period to determine the base period return; and multiplying the base
period return by (365/7). The Fund's effective yield is computed by compounding
the unannualized base period return by adding 1 to the base period return;
raising the sum to the 365/7th power; and subtracting 1 from the result.
 
For the seven-day period ended December 31, 1997, the Fund's Class A share yield
was 4.55% and effective yield was 4.66%. The seven-day and effective yields are

The Fund's investment results may also be calculated for longer periods in
accordance with the following method: by subtracting (a) the net asset value of
one share at the beginning of the period, from (b) the net asset value of all
shares an investor would own at the end of the period for the share held at the
beginning of the period (assuming reinvestment of all dividends and
distributions) and dividing by (c) the net asset value per share at the
beginning of the period. The resulting percentage indicates the positive or
negative rate of return that an investor would have earned from the reinvested
dividends and distributions and any changes in share price during the period.
 
The Fund's "Standardized Return," as referred to in the Prospectus (see "Other
Information -- Performance Information" in the Prospectus), is calculated as
follows: Standardized Return ("T") is computed by using the value at the end of
the period ("EV") of a hypothetical initial investment of $1,000 ("P") over a
period of years ("n") according to the following formula as required by the SEC:
P(1+T) to the (n)th power = EV. The following assumption will be reflected in
computations made in accordance with this formula: reinvestment of dividends and
other distributions at net asset value on the reinvestment date determined by
the Board.

"Non-Standardized Return," as referred to in the Prospectus, is calculated for a
specified period of time by assuming the investment of $1,000 in Fund shares and
further assuming the reinvestment of all dividends and other distributions made
to Fund shareholders in additional Fund shares at their net asset value.
Percentage rates of return are then calculated by comparing this assumed initial
investment to the value of the hypothetical account at the end of the period for
which the Non-Standardized Return is quoted. As discussed in the Prospectus, the
Fund may quote Non-Standardized Returns that do not reflect the effect of
contingent deferred sales charges. Non-Standardized Returns may be quoted from
the same or different time periods for which Standardized Returns are quoted.

The Fund's investment results will vary from time to time depending upon market
conditions, the composition of the Fund's portfolio and operating expenses of
the Fund, so that current or past yield or total return figures should not be
considered representative of what an investment in the 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 the Fund's
investment results with those published for other investment companies and other
investment vehicles. Investment results also should be considered relative to
the risks associated with the investment objective and policies. The Fund's
investment results will be calculated separately for Class A and Class B shares.
The Fund will include performance data for both Class A and Class B shares of
the Fund in any advertisement or information including performance data for the
Fund.
 
IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKETS
   
The Fund and AIM Distributors may from time to time, in advertisements, sales
literature and reports furnished to present or prospective shareholders, compare
the Fund with the following, among others:
    
 
        (1) The Salomon Brothers Non-U.S. Dollars Indices, which are measures of
    the total return performance of high quality non-U.S. dollar denominated
    securities in major sectors of the worldwide bond markets.
 
        (2) The Lehman Brothers Government/Corporate Bond Index, which is a
    comprehensive measure of all public obligations of the U.S. Treasury
    (excluding flower bonds and foreign targeted issues), all publicly issued
    debt of agencies of the U.S. Government (excluding mortgage backed
    securities), and all public, fixed rate, non-convertible investment grade
    domestic corporate debt rated at least Baa by Moody's Investors Service,
    Inc. ("Moody's") or BBB by Standard and Poor's Ratings Group ("S&P"), or, in
    the case of nonrated bonds, BBB by Fitch Investors Service ("Fitch")
    (excluding Collateralized Mortgage Obligations).
 
   
        (3) Average of savings accounts, which is a measure of all kinds of
    savings deposits, including longer-term certificates (based on figures
    supplied by the U.S. League of Savings Institutions). Savings accounts offer
    a guaranteed rate of return on principal, but no opportunity for capital
    growth. The maximum rates paid on some savings deposits are currently fixed
    by law.
    
 
        (4) The Consumer Price Index ("CPI"), which is a measure of the average
    change in prices over time in a fixed market basket of goods and services
    (e.g., food, clothing, shelter, fuels, transportation fares, charges for
    doctors' and dentists' services, prescription medicines, and other goods and
    services that people buy for day-to-day living). There is inflation risk
    which does not affect a security's value but its purchasing power, i.e., the
    risk of changing price levels in the economy that affects security prices or
    the price of goods and services.
 
        (5) Data and mutual fund rankings published or prepared by Lipper
    Analytical Data Services, Inc. ("Lipper"), CDA/Wiesenberger Investment
    Company Service ("CDA/Wiesenberger"), Morningstar, Inc. ("Morningstar"),
    Micropal, Inc. and/or other companies that rank and/or compare mutual funds
    by overall performance, investment objectives, assets, expense levels,
    periods of existence and/or other factors. In this regard the Fund may be
    compared to its "peer group" as defined by Lipper, CDA/Wiesenberger,
    Morningstar and/or other firms, as applicable, or to specific funds or
    groups of funds within or outside of such peer group. Lipper generally ranks
    funds on the basis of total return, assuming reinvestment of distributions,
    but does not take sales charges or redemption fees into consideration, and
    is prepared without regard to tax consequences. In addition to the mutual
    fund rankings, the Fund's performance may be compared to mutual fund
    performance indices prepared by Lipper. Morningstar is a mutual fund rating
    service that also rates mutual funds on the basis of risk-adjusted
    performance. Morningstar ratings are calculated from a fund's three, five
    and ten year average annual returns with appropriate fee adjustments and a
    risk factor that reflects fund performance relative to the three-month U.S.
    Treasury bill monthly returns. Ten percent of the funds in an investment
    category receive five stars and 22.5% receive four stars. The ratings are
    subject to change each month.
 
        (6) Bear Stearns Foreign Bond Index, which provides simple average
    returns for individual countries and gross national product ("GNP")-weighted
    index, beginning in 1975. The returns are broken down by local market and
    currency.

                             GT GLOBAL DOLLAR FUND
 
        (7) Ibbotson Associates International Bond Index, which provides a
    detailed breakdown of local market and currency returns since 1960.
 
        (8) Salomon Brothers Broad Investment Grade Index, which is a widely
    used index composed of U.S. domestic government, corporate and
    mortgage-backed fixed income securities.
 
        (9) Salomon Brothers World Government Bond Index and Salomon Brothers
    World Government Bond Index-Non-U.S., each of which is a widely used index
    composed of world government bonds.
 
       (10) The World Bank Publication of Trends in Developing Countries
    ("TIDE"), which provides brief reports on most of the World Bank's borrowing
    members. The World Development Report is published annually and looks at
    global and regional economic trends and their implications for the
    developing economies.
 
       (11) Datastream and Worldscope, each of which is an on-line database
    retrieval service for information, including international financial and
    economic data.
 
       (12) International Financial Statistics, which is produced by the
    International Monetary Fund.
 
       (13) Various publications and reports produced by the World Bank and its
    affiliates.
 
       (14) Various publications from the International Bank for Reconstruction
    and Development.
 
       (15) Various publications produced by ratings agencies such as Moody's,
    S&P and Fitch.
 
       (16) Privatizations from various sources, stock market capitalization,
    number of issuers, and trading volume of newly privatized companies and, in
    addition, projected levels of privatization. Privatization, an economic
    process virtually unknown in the U.S., is the selling of state-owned
    companies to the private sector. Under private ownership, such companies can
    release assets and seek to make profits free from political intervention.
    Examples of state-owned industries being privatized outside the U.S. include
    airlines, telecommunications, utilities and financial institutions.
 
   
Indices, economic and financial data prepared by the research departments of
various financial organizations, such as Salomon Brothers, Inc., Lehman
Brothers, Merrill Lynch, Pierce, Fenner & Smith, Inc., Financial Research
Corporation, J. P. Morgan, Morgan Stanley, Smith Barney Shearson, S.G. Warburg,
Jardine Flemming, The Bank for International Settlements, Asian Development
Bank, Bloomberg, L.P. and Ibbotson Associates, may be used, as well as
information reported by the Federal Reserve and the respective central banks of
various nations. In addition, AIM Distributors may use performance rankings,
ratings and commentary reported periodically in national financial publications,
including Money Magazine, Mutual Fund Magazine, Smart Money, Global Finance,
EuroMoney, Financial World, Forbes, Fortune, Business Week, Latin Finance, the
Wall Street Journal, Emerging Markets Weekly, Kiplinger's Guide To Personal
Finance, Barron's, The Financial Times, USA Today, The New York Times, Far
Eastern Economic Review, The Economist and Investors Business Digest. Each Fund
may compare its performance to that of other compilations or indices of
comparable quality to those listed above and other indices that may be developed
and made available in the future.
    
 
The Fund may compare its performance to that of other compilations or indices of
comparable quality to those listed above which may be developed and made
available in the future. The Fund may be compared in advertising to Certificates
of Deposit (CDs), the Bank Rate Monitor National Index, an average of the quoted
rates for 100 leading banks and thrifts in ten U.S. cities chosen to represent
the ten largest Consumer Metropolitan statistical areas, or other investments
issued by banks. The Fund differs from bank investments in several respects. The
Fund may offer greater liquidity or higher potential returns than CDs; but
unlike CDs, the Fund will have a fluctuating share price and return and is not
FDIC insured.
 
   
AIM Distributors may provide information designed to help individuals understand
their investment goals and explore various financial strategies. For example,
AIM Distributors may describe general principles of investing, such as asset
allocation, diversification and risk tolerance.
    
 
   
In advertising and sales materials, AIM Distributors may make reference to or
discuss its products and services, which may include: retirement investing; the
effects of dollar-cost averaging and saving for college or a home. In addition,
AIM Distributors may quote financial or business publications and periodicals,
including model portfolios or allocations, as they relate to fund management,
investment philosophy, and investment techniques.
    
 
The Fund may quote various measures of volatility and benchmark correlation such
as beta, standard deviation and R(2) in advertising. In addition, the Fund may
compare these measures to those of other funds. Measures of volatility seek to
compare the Fund's total returns compared to those of a benchmark. All measures
of volatility and correlation are calculated using averages of historical data.

                             GT GLOBAL DOLLAR FUND
 
The Fund may advertise examples of the effects of periodic investment plans,
including the principle of dollar cost averaging. In such a program, an investor
invests a fixed dollar amount in a fund at periodic intervals, thereby
purchasing fewer shares when prices are high and more shares when prices are
low. While such a strategy does not assure a profit or guard against loss in a
declining market, the investor's average cost per share can be lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating such
a plan, investors should consider their ability to continue purchasing shares
through periods of low price levels.
 
The Fund may describe in its sales material and advertisements how an investor
may invest in the GT Global Mutual Funds through various retirement plans or
other programs that offer deferral of income taxes on investment earnings and
pursuant to which an investor may make deductible contributions. Because of
their advantages, these retirement plans and programs may produce returns
superior to comparable non-retirement investments. For example, a $10,000
investment earning a taxable return of 10% annually would have an after-tax
value of $17,976 after ten years, assuming tax was deducted from the return each
year at a 39.6% rate. An equivalent tax-deferred investment would have an
after-tax value of $19,626 after ten years, assuming tax was deducted at a 39.6%
rate from the deferred earnings at the end of the ten-year period. In sales
materials and advertisements, the Fund may also discuss these plans and
programs. See "Information Relating to Sales and Redemptions -- Individual
Retirement Accounts ('IRAs') and Other Tax-Deferred Plans."
 
   
In advertising and sales materials, AIM Distributors may make reference to or
discuss its products, services and accomplishments. Among these accomplishments
are that in 1983 the Sub-adviser provided assistance to the government of Hong
Kong in linking its currency to the U.S. dollar, and that in 1987 Japan's
Ministry of Finance licensed GT Asset Management Ltd. as one of the first
foreign discretionary investment managers for Japanese investors. Such
accomplishments, however, should not be viewed as an endorsement of the
Sub-adviser by the government of Hong Kong, Japan's Ministry of Finance or any
other government or government agency. Nor do any such accomplishments of the
Sub-adviser provide any assurance that the GT Global Mutual Funds' investment
objectives will be achieved.

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
COMMERCIAL PAPER RATINGS
    S&P. "A-1" and "A-2" are the two highest commercial paper rating categories:
 
        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 are denoted with a plus sign (+) designation.
 
        A-2. Capacity for timely payment on issues with this designation is
    satisfactory. However, the relative degree of safety is not as high as for
    issues designated "A-1".

    MOODY'S. "Prime-1" and "Prime-2" are the two highest commercial paper rating
categories.
 
        Prime-1. Issuers (or supporting institutions) assigned this highest
    rating have 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.
 
        Prime-2. Issuers (or supporting institutions) assigned this rating have
    a strong ability for repayment of senior short-term debt obligations. This
    will normally 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.
 
BOND RATINGS
 
    S&P: Its ratings for high quality bonds are as follows:
 
        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.
 
        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.
 
    MOODY'S: Its ratings for high quality bonds are as follows:
 
        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.
 
        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.
 
NOTE RATINGS
    S&P: The SP-1 rating denotes a very strong or strong capacity to pay
principal and interest. Those issues determined to possess overwhelming safety
characteristics will be given a plus (+) designation.
 
The SP-2 rating denotes a satisfactory capacity to pay principal and interest.
 
    MOODY'S: The MIG 1 designation denotes best quality. There is strong
protection by established cash flows, superior liquidity support or demonstrated
broad-based access to the market for refinancing.
 
The MIG 2 designation denotes high quality. Margins of protection are ample
although not as large as in the preceding group.

ITEM 27. INDEMNIFICATION
 
    Section 2-148 of the Maryland General Corporation Law and Article X of
Registrant's By-Laws provide 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 ("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.
