                               PROSPECTUS SUMMARY
- ------------------------------------------------------------
The following summary is qualified in its entirety by the more detailed
information appearing in the body of this Prospectus. Cross-references in the
summary are to headings in the body of this Prospectus.
 
   
<TABLE>
<S>                            <C>                               <C>
The Fund:                                       The Fund is a non-diversified series of G.T. Investment Funds, Inc.
 
Investment Objective:          The  Fund  seeks  long-term  capital  appreciation  together  with
                               current income.
 
Principal Investments:         The Fund invests primarily in blue-chip equity securities and high
                               quality government bonds of issuers  located in the United  States
                               and throughout the world.
 
Principal Risk Factors:        There  is no assurance  that the Fund  will achieve its investment
                               objective. The Fund's net  asset value will fluctuate,  reflecting
                               fluctuations  in the market  value of its  portfolio holdings. The
                               value of debt  securities held  by the  Fund generally  fluctuates
                               inversely  with interest rate  movements. Certain investment grade
                               debt securities may possess speculative qualities.
 
                               The Fund may invest in foreign securities. Investments in  foreign
                               securities  involve  risks  relating  to  political  and  economic
                               developments abroad and the differences between the regulations to
                               which U.S.  and foreign  issuers are  subject. Individual  foreign
                               economies  also may differ favorably  or unfavorably from the U.S.
                               economy. Changes in  foreign currency exchange  rates will  affect
                               the Fund's net asset value, earnings and gains and losses realized
                               on  sales of  securities. Securities  of foreign  companies may be
                               less  liquid  and  their  prices  more  volatile  than  those   of
                               securities of comparable U.S. companies.
 
                               The  Fund  may engage  in  certain foreign  currency,  options and
                               futures transactions to attempt to hedge against the overall level
                               of investment and  currency risk  associated with  its present  or
                               planned  investments. Such transactions  involve certain risks and
                               transaction costs.
 
                               See "Investment Objective and Policies."
 
Investment Manager:            The Manager is part of  Liechtenstein Global Trust, a provider  of
                               global  asset management and private banking products and services
                               to  individual   and  institutional   investors,  entrusted   with
                               approximately $79 billion in total assets as of December 31, 1997.
                               The Manager and its worldwide asset management affiliates maintain
                               investment  offices in Frankfurt, Hong Kong, London, New York, San
                               Francisco, Singapore, Sydney, Tokyo and Toronto. See "Management."
 
Alternative Purchase Plan:     Investors may select Class  A or Class B  shares, each subject  to
                               different  expenses and  a different sales  charge structure. Each
                               class has  distinct  advantages and  disadvantages  for  different
                               investors,  and investors should choose  the class that best suits
                               their circumstances and objectives. See "How to Invest."
 
  Class A Shares:              Offered at  net  asset  value plus  any  applicable  sales  charge
                               (maximum  is 4.75% of public offering  price) and subject to 12b-1
                               service and  distribution fees  at the  annualized rate  of up  to
                               0.35% of the average daily net assets of Class A shares.

- ------------------
 
(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
    EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE EXPENSES. THE FUND'S
    ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN. The tables and the
    assumption in the example of a 5% annual return are required by regulation
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.
 
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase; the charge generally
    declines by 1% annually thereafter, reaching zero after six years. See "How
    to Invest."
 
(3) Expenses are based on the Fund's fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agent, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information. 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 payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.

                              INVESTMENT OBJECTIVE
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
The Fund's investment objective is long-term capital appreciation together with
current income. The Fund seeks its objective by investing in a global portfolio
of both equity and debt securities, allocated among diverse international
markets. There is no assurance that the Fund's investment objective will be
achieved.
 
At least 65% of the Fund's total assets normally will be invested in a
combination of blue-chip equity securities and high quality government bonds.
The Fund considers an equity security to be "blue chip" if: (i) during the
issuer's most recent fiscal year the security offered an above average dividend
yield relative to the latest reported dividend yield on the Morgan Stanley
Capital International World Index; AND (ii) the total equity market
capitalization of the issuer is at least $1 billion. Government bonds are deemed
to be high quality if at the time of the Fund's investment they are rated within
one of the two highest ratings categories of Moody's Investors Service, Inc.
("Moody's") or by Standard & Poor's, a division of The McGraw-Hill Companies,
Inc. ("S&P"), or, if not rated, are deemed to be of equivalent quality in the
judgment of the Manager.
 
Up to 35% of the Fund's total assets may be invested in other equity securities
and investment grade government and corporate debt obligations which the Manager
believes will assist the Fund in achieving its objective. "Investment grade"
debt securities are those rated within one of the four highest ratings
categories of Moody's or S&P, or, if not rated, deemed to be of equivalent
quality in the judgment of the Manager.
 
Equity securities that the Fund may purchase include common stocks, preferred
stocks and warrants to acquire such stocks and other equity securities.
Government bonds that the Fund may purchase include debt obligations issued or
guaranteed by the United States or foreign governments (including foreign
states, provinces or municipalities) or their agencies, authorities or
instrumentalities and debt obligations of supranational entities organized or
supported by several national governments, such as the World Bank and the Asian
Development Bank. The debt obligations held by the Fund may include debt
obligations convertible into equity securities or having attached warrants or
rights to purchase equity securities. The Fund may purchase securities that are
issued by the government or a corporation or financial institution of one nation
but denominated in the currency of another nation (or a multinational currency
unit).
 
According to the Manager, as of the date of this Prospectus, more than 50% of
the total equity market capitalization worldwide is represented by non-U.S.
equity securities, and more than 50% of the value of all outstanding government
debt obligations throughout the world is represented by obligations denominated
in currencies other than the U.S. dollar. Moreover, from time to time the equity
and debt securities of issuers located outside the United States have
substantially outperformed the equity and debt securities of U.S. issuers.
Accordingly, the Manager believes that the Fund's policy of investing in a
global portfolio of equity and debt securities may enable the achievement of
long-term results superior to those produced by mutual funds with similar
objectives to that of the Fund that invest solely in U.S. equity and debt
securities.
 
SELECTION OF INVESTMENTS AND ASSET ALLOCATION. Consistent with the Fund's
investment objective, the Manager employs a conservative investment style in
managing the Fund's assets. In so doing the Manager attempts to limit volatility
and risk to capital. The Manager allocates the Fund's assets among securities of
countries and in currency denominations where opportunities for meeting the
Fund's investment objective are expected to be the most attractive. The Manager
attempts to identify those countries and industries where economic and political
factors are likely to produce above-average growth rates and to further identify
companies in such countries and industries that are best positioned and managed
to benefit from these factors.
 
The Fund currently contemplates that it will invest principally in securities of
issuers in the United States, Canada, Japan, Western Europe, New Zealand and
Australia. The Fund may invest substantially in securities denominated in one or
more currencies. Under normal conditions, the Fund invests in issuers of not
less than three different countries and issuers of any one country,
 
                               Prospectus Page 8
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
other than the United States, will represent no more than 40% of the Fund's
total assets.
 
The relative proportions of equity and debt securities held by the Fund at any
one time will vary, depending upon the Manager's assessment of global political
and economic conditions and the relative strengths and weaknesses of the world
equity and debt markets. To enable the Fund to respond to general economic
changes and market conditions around the world, the Fund is authorized to invest
up to 100% of its total assets in either equity securities or debt securities.
 
In selecting equity securities for investment, the Manager attempts to identify
and acquire only securities it deems to represent high or improving investment
quality. Securities representing high investment quality generally will include
those of well-known, established and successful issuers that the Manager
believes will continue to be successful in the future. Securities representing
improving investment quality may include those of an issuer that has improved
its sales or earnings or of an issuer the balance sheet and financial condition
of which is improving. The Manager seeks to avoid investing in equity securities
that appear overly speculative or risky, even if they have attractive features
or investment potential.
 
In evaluating debt securities considered for the Fund, the Manager analyzes
their yield, maturity, issue classification and quality characteristics, coupled
with expectations regarding local and world economies, movements in the general
level and term of interest rates, currency values, political developments, and
variations in the supply of funds available for investment in the world bond
market relative to the demands placed upon it. There are no limitations on the
maximum or minimum maturities of the debt securities considered by the Fund or
on the average weighted maturity of the debt portion of the Fund's portfolio.
Should the rating of a debt security be revised while such security is owned by
the Fund, the Manager will evaluate what action, if any, is appropriate with
respect to such security.
 
The Manager generally evaluates currencies on the basis of fundamental economic
criteria (e.g., relative inflation and interest rate levels and trends, growth
rate forecasts, balance of payments status and economic policies) as well as
technical and political data. The Fund may seek to protect itself against
negative currency movements by engaging in hedging techniques through the use of
options, futures and forward currency contracts.
 
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Manager may employ a temporary defensive investment strategy if it
determines such a strategy to be warranted due to market, economic or political
conditions. Under a defensive strategy, the Fund may hold cash (U.S. dollars,
foreign currencies or multinational currency units) and/or invest any portion or
all of its assets in high quality money market instruments of U.S. or foreign
issuers. In addition, for temporary defensive purposes, most or all of the
Fund's investments may be made in the United States and denominated in U.S.
dollars. To the extent the Fund adopts a temporary defensive posture, it will
not be invested so as to directly achieve its investment objective. In addition,
pending investment of proceeds from new sales of Fund shares or in order to meet
ordinary daily cash needs, the Fund may hold cash (U.S. dollars, foreign
currencies or multinational currency units) and may invest in foreign or
domestic high quality money market instruments.
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Fund may
borrow from banks or may borrow through reverse repurchase agreements and "roll"
transactions in connection with meeting requests for the redemption of Fund
shares. The Fund also may borrow up to 5% of its total assets for temporary or
emergency purposes other than to meet redemptions. The Fund may borrow up to
33 1/3% of its total assets. However, the Fund will not purchase securities
while borrowings in excess of 5% of the Fund's total assets are outstanding. Any
borrowing by the Fund may cause greater fluctuation in the value of its shares
than would be the case if the Fund did not borrow.
 
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash, and agrees to repurchase the security in the
future at an agreed upon price which includes an interest component. A "roll"
borrowing transaction involves the Fund's sale of securities together with its
commitment (for which the Fund may receive a fee) to purchase similar, but not
identical, securities at a future date.
 
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower
 
                               Prospectus Page 9
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
must maintain with the Fund's custodian collateral consisting of cash, U.S.
government securities or certain irrevocable letters of credit equal to at least
100% of the value of the borrowed securities, plus any accrued interest or such
other collateral as permitted by the Fund's investment program and regulatory
agencies, and as approved by the Board. The risks in lending portfolio
securities, as with other extensions of secured credit, consist of possible
delays in receiving additional collateral or in recovery of the securities and
possible loss of rights in the collateral should the borrower fail financially.
 
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally will not be registered with, nor the
issuers thereof be subject to the reporting requirements of the SEC.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available about domestic securities and issuers.
Foreign companies generally are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies. In addition, certain costs attributable to
foreign investing, such as custody charges, are higher than those attributable
to domestic investing. Securities of some foreign companies are less liquid and
their prices may be more volatile than securities of comparable domestic
companies. The Fund's net investment income from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing the Fund's net investment
income.
 
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic or
economic developments which could affect the Fund's investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, rate of savings and capital reinvestment, resource
self-sufficiency and balance of payments positions. Investments in foreign
government securities involve special risks, including the risk that the
government issuers may be unable or unwilling to repay principal and interest
when due.
 
The Fund will also be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between such currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Fund's shares, and also may affect the value of dividends and interest earned by
the Fund and gains and losses realized by the Fund.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. To attempt to increase
return, the Fund may write call options on securities. This strategy will be
employed only when, in the opinion of the Manager, the size of the premium the
Fund receives for writing the option is adequate to compensate the Fund against
the risk that appreciation in the underlying security may not be fully realized
if the option is exercised. The Fund also is authorized to write put options to
attempt to enhance return, although it does not have the current intention of so
doing.
 
The Fund may also use forward currency contracts, futures contracts, options on
securities, options on currencies, options on indices and options on futures
contracts to attempt to hedge against the overall level of investment and
currency risk normally associated with the Fund's investments. These instruments
are often referred to as "derivatives," which may be defined as financial
instruments whose performance is derived, at least in part, from the performance
of another asset (such as a security, currency, or an index of securities). The
Fund may enter into such instruments up to the full value of its portfolio
assets. See "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
 
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar, or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to the
Fund's portfolio positions. The Fund also may purchase and sell put and call
options on currencies, futures contracts on currencies and options on such
futures contracts to hedge the Fund's portfolio against movements in exchange
rates.
 
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the Manager intends to include in the Fund's
portfolio. The Fund also may purchase and sell put and call options on stock
indices to hedge against overall fluctuations in the securities markets or in a
specific market sector.
 
                               Prospectus Page 10
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or a specific market sector decline that could adversely affect the
Fund's portfolio. The Fund also may purchase index futures contracts and
purchase call options or write put options on such contracts to hedge against a
general market or market sector advance and thereby attempt to lessen the cost
of future securities acquisitions. Similarly, the Fund may use interest rate
futures contracts and options thereon to hedge the debt portion of its portfolio
against changes in the general level of interest rates.
 
Although the Fund is authorized to enter into options, futures and forward
currency transactions, the Fund might not enter into any such transactions.
Options, futures and foreign currency transactions involve certain risks, which
include: (1) dependence on the Manager's ability to predict movements in the
prices of individual securities, fluctuations in the general securities markets
and movements in interest rates and currency markets; (2) imperfect correlation,
or even no correlation, between movements in the price of forward contracts,
options, futures contracts or options thereon and movements in the price of the
currency or security hedged or used for cover; (3) the fact that the skills and
techniques needed to trade options, futures contracts and options thereon or to
use forward currency contracts are different from those needed to select the
securities in which the Fund invests; (4) the lack of assurance that a liquid
secondary market will exist for any particular option, futures contract or
option thereon at any particular time; (5) the possible loss of principal under
certain conditions; and (6) the possible inability of the Fund to purchase or
sell a portfolio security at a time when it would otherwise be favorable for it
to do so, or the possible need for the Fund to sell a security at a
disadvantageous time, due to the need for the Fund to maintain "cover" or to set
aside securities in connection with hedging transactions.
 
OTHER POLICIES AND RISKS. The Fund's net asset value will fluctuate, reflecting
fluctuations in the market value of its portfolio positions. Equity securities,
particularly common stocks, generally represent the most junior position in an
issuer's capital structure, and entitle holders to an interest in the assets of
an issuer, if any, remaining after all more senior claims have been satisfied.
The value of equity securities held by the Fund will fluctuate in response to
general market and economic developments, as well as developments affecting the
particular issuers of such securities. In addition, the value of debt securities
held by the Fund generally will fluctuate with changes in the perceived
creditworthiness of the issuers of such securities and movements in interest
rates. Investment grade debt securities rated Baa by Moody's are described by
Moody's as having speculative characteristics, and therefore may be affected by
economic conditions and changes in the circumstances of their issuers to a
greater extent than higher rated bonds.
 
The Fund may invest up to 10% of its net assets in illiquid securities and other
securities for which no readily available market exists. The Fund may also
invest up to 5% of its total assets in a combination of securities purchased on
a when-issued basis or with respect to which it has entered into forward
commitment agreements.
 
The Fund is classified under the Investment Company Act of 1940, as amended
("1940 Act") as a "non-diversified" fund. As a result, the Fund will be able to
invest in a fewer number of issuers than if it were classified under the 1940
Act as a "diversified" fund. To the extent that the Fund invests in a smaller
number of issuers, the value of the Fund's shares may fluctuate more widely and
the Fund may be subject to greater investment and credit risk with respect to
its portfolio.
 
OTHER INFORMATION. The Fund's investment objective may not be changed without
the approval of a majority of the Fund's outstanding voting securities. A
"majority of the Fund's outstanding voting securities" means the lesser of (i)
67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented, or (ii) more than 50% of the outstanding
shares. In addition, the Fund has adopted certain investment limitations which
also may not be changed without shareholder approval. A complete description of
these limitations is included in the Statement of Additional Information. Unless
specifically noted, the Fund's investment policies described in this Prospectus
and in the Statement of Additional Information may be changed by the Company's
Board of Directors without shareholder approval. The Fund's policies regarding
lending, and the percentage of Fund assets that may be committed to borrowing,
are fundamental policies and may not be changed without shareholder approval.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
   
GENERAL. Shares of the Fund may be purchased through Financial Institutions,
some of which may charge the investor a transaction fee. That fee will be in
addition to the sales charge payable by the investor, with respect to Class A
shares. 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, which includes any applicable sales charge for Class A
shares. 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 public
offering price for the applicable class of shares 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 or
quarterly 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).
THE FUND AND GT GLOBAL 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
GT Global may reject purchase orders or exchanges by investors who appear to
follow, in the Manager's judgment, a market-timing strategy or otherwise engage
in excessive trading. See "How to Make Exchanges -- Limitations on Purchase
Orders and Exchanges."
 
WHEN PLACING PURCHASE ORDERS, INVESTORS SHOULD SPECIFY WHETHER THE ORDER IS FOR
CLASS A OR CLASS B SHARES OF THE FUND. ALL PURCHASE ORDERS THAT FAIL TO SPECIFY
A CLASS WILL AUTOMATICALLY BE INVESTED IN CLASS A SHARES. PURCHASES OF $500,000
OR MORE MUST BE FOR CLASS A SHARES.
 
   
PURCHASES THROUGH GT GLOBAL. 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 GT Global.
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 public
offering price next determined after the Transfer Agent has received the Account
Application and check. Subsequent investments do not need to be accompanied by
an application.
    
 
Investors also may purchase shares of the Fund through GT Global by bank wire.
Bank wire purchases will be effected at the next determined public offering
price 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 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.

                         GT GLOBAL GROWTH & INCOME FUND
 
CERTIFICATES. Physical certificates representing the Fund's shares will not be
issued unless a written request is submitted to the Transfer Agent. Shares of
the Fund are recorded on a register by the Transfer Agent, and shareholders who
do not elect to receive certificates have the same rights of ownership as if
certificates had been issued to them. Redemptions and exchanges by shareholders
who hold certificates may take longer to effect than similar transactions
involving non-certificated shares because the physical delivery and processing
of properly executed certificates is required. ACCORDINGLY, THE FUND AND GT
GLOBAL RECOMMEND THAT SHAREHOLDERS DO NOT REQUEST ISSUANCE OF CERTIFICATES.
DIFFERENCES BETWEEN THE CLASSES. The primary difference between the classes of
the Fund's shares offered through this Prospectus lies in their sales charge
structures and ongoing expenses, 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.
 
   
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. Large investments may qualify for a
reduced Class A sales charge. Investors in Class B shares have 100% of the
purchase invested immediately. Consult your financial adviser. Financial
Institutions may receive different levels of compensation for selling a
particular class of shares.
    
 
   
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 Liechtenstein Global Trust; (e) any of those
companies; and (f) GT Global New Dimension Fund.
    
 
                           PURCHASING CLASS A SHARES
 
The Fund's public offering price for Class A shares is the next determined net
asset value per share (see "Calculation of Net Asset Value") including any sales
charge determined in accordance with the following schedule:

- ------------------
*   GT Global will pay the following commissions to broker/ dealers that
    initiate and are responsible for purchases by any single purchaser of Class
    A shares of $500,000 or more in the aggregate: 1.00% of the purchase amount
    up to $3 million, plus 0.50% on the excess over $3 million. For purposes of
    determining the appropriate commission to be paid in connection with the
    transaction, GT Global will combine purchases made by a broker/dealer on
    behalf of a single client so that the broker/dealer's commission, as
    outlined above, will be based on the aggregate amount of such client's share
    purchases over a rolling twelve month period from the date of the
    transaction.
 
+   All shares purchased without a sales charge based on the aggregate purchase
    amount equalling at least $500,000 will be subject to a contingent deferred
    sales charge, for the first year after their purchase equal to 1% of the
    lower of the original purchase price or the net asset value of such shares
    at the time of redemption. See "Contingent Deferred Sales Charge -- Class A
    Shares."
 
From time to time, GT Global may reallow to broker/ dealers the full amount of
the sales charge or may pay out additional amounts to broker/dealers who sell
Class A shares. In some instances, GT Global may offer these reallowances or
additional payments only to broker/dealers that have sold or may sell
significant amounts of Class A shares. To the extent that GT Global reallows the
full amount of the sales charge to broker/dealers, such broker/dealers may be
deemed to be underwriters under the Securities Act of 1933, as amended.
Commissions also may be paid to broker/dealers and other financial institutions
that initiate purchases of at least $500,000 made pursuant to sales charge
waivers (i)
 
                               Prospectus Page 13
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
and (vii) described below under "Sales Charge Waivers -- Class A Shares."
 
The following purchases may be aggregated for purposes of determining the
"Amount of Purchase":
 
(a) Individual purchases on behalf of a single purchaser, the purchaser's spouse
and their children under the age of 21 years including purchases in connection
with an employee benefit plan or plans exclusively for the benefit of such
individual(s), such as an IRA, individual Code Section 403(b) plan or
single-participant self-employed individual retirement plan ("Keogh Plan") and
purchases made by a company controlled by such individual(s);
 
(b) Individual purchases by a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account, including an employee benefit
plan (such as employer-sponsored pension, profit-sharing and stock bonus plans,
including plans under Code Section 401(k), and medical, life and disability
insurance trusts) other than a plan described in "(a)" above;
 
and
 
(c) Individual purchases by a trustee or other fiduciary purchasing shares
concurrently for two or more employee benefit plans of a single employer or of
employers affiliated with each other (again excluding an employee benefit plan
described in "(a)" above).
 
SALES CHARGE WAIVERS -- CLASS A SHARES. Class A shares are sold at net asset
value without imposition of sales charges when investments are made by the

                         GT GLOBAL GROWTH & INCOME FUND
who have continuously held shares in the GT Global Mutual Funds since that time.
 
REINSTATEMENT PRIVILEGE. Shareholders who redeem their Class A shares in the
Fund have a one-time privilege of reinstating their investment by investing the
proceeds of the redemption at net asset value without a sales charge in Class A
shares of the Fund and/or one or more of the other GT Global Mutual Funds. The
Transfer Agent must receive from the investor or the investor's broker/dealer
within 180 days after the date of the redemption both a written request for
reinvestment and a check not exceeding the amount of the redemption proceeds.
The reinstatement purchase will be effected at the net asset value per share
next determined after such receipt. Gain on the redemption is taxable
notwithstanding exercise of the reinvestment privilege although loss thereon
might not be deductible as a result of such exercise. See "Dividends, Other
Distributions and Federal Income Taxation."
 
   
REDUCED SALES CHARGE PLANS -- CLASS A SHARES. Class A shares of the Fund may be
purchased at reduced sales charges either through the Right of Accumulation or
under a Letter of Intent. Investors should contact their Financial Institution
or the Transfer Agent for more information.
    
 
   
RIGHT OF ACCUMULATION. Pursuant to the Right of Accumulation, investors are
permitted to purchase shares of the Fund at the sales charge applicable to the
total of (a) the dollar amount then being purchased plus (b) the dollar amount
of the investor's concurrent purchases of other GT Global Mutual Funds (other
than GT Global Dollar Fund) plus (c) the price of all shares of GT Global Mutual
Funds (other than shares of GT Global Dollar Fund not acquired by exchange)
already held by the investor. To receive the Right of Accumulation, at the time
of purchase investors must give their Financial Institution, the Transfer Agent
or GT Global sufficient information to permit confirmation of qualification. THE
FOREGOING RIGHT OF ACCUMULATION APPLIES ONLY TO CLASS A SHARES OF THE FUND AND
OTHER GT GLOBAL MUTUAL FUNDS (OTHER THAN GT GLOBAL DOLLAR FUND).
    
 
LETTER OF INTENT. In executing a Letter of Intent ("LOI"), an investor indicates
an aggregate investment amount he or she intends to invest in the Class A shares
of the Fund and the Class A shares of other GT Global Mutual Funds (other than
shares of GT Global Dollar Fund) in the following thirteen months. The LOI is
included as part of the Account Application located at the end of this
Prospectus. The sales charge applicable to that aggregate amount then becomes
the applicable sales charge on all purchases made concurrently with the
execution of the LOI and in the thirteen months following that execution. If an
investor executes an LOI within 90 days of a prior purchase of GT Global Mutual
Fund Class A shares (other than shares of GT Global Dollar Fund), the prior
purchase may be included under the LOI and an appropriate adjustment, if any,
with respect to the sales charges paid by the investor in connection with the
prior purchase will be made, based on the then-current net asset value(s) of the
pertinent Fund(s).
 
If at the end of the thirteen month period covered by the LOI the total amount
of purchases does not equal the amount indicated, the investor will be required
to pay the difference between the sales charges paid at the reduced rate and the
sales charges applicable to the purchases actually made. Shares having a value
equal to 5% of the amount specified in the LOI will be held in escrow during the
thirteen month period (while remaining registered in the investor's name) and
are subject to redemption to assure any necessary payment to GT Global of a
higher applicable sales charge.
 
For purposes of an LOI, any registered investment adviser, trust company or bank
trust department which exercises investment discretion and which intends within
thirteen months to invest $500,000 or more can be treated as a single purchaser,
provided further that such entity places all purchase and redemption orders.
Such entities should be prepared to establish their qualification for such
treatment. THE FOREGOING LOI APPLIES ONLY TO CLASS A SHARES OF THE FUND AND
OTHER GT GLOBAL MUTUAL FUNDS (OTHER THAN GT GLOBAL DOLLAR FUND).
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS A SHARES. Purchases of Class A shares
of $500,000 or more may be made without a sales charge. If a shareholder within
one year after the date of purchase redeems any Class A shares that were
purchased without a sales charge by reason of a purchase of $500,000 or more, a
contingent deferred sales charge of 1% of the lower of the original purchase
price or the net asset value of such shares at the time of redemption will be
charged. Class A shares will not be subject to the contingent deferred sales
charge to the extent that the value of such shares represents: (1) reinvestment
of dividends or other distributions or (2) shares redeemed more than one year
after their purchase. Such shares purchased without a sales charge may
 
                               Prospectus Page 15
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
be exchanged for Class A shares of another GT Global Mutual Fund (other than GT
Global Dollar Fund) without the imposition of a contingent deferred sales
charge, although the contingent deferred sales charge described above will apply
to the redemption of the shares acquired through an exchange. The waivers set
forth under "Contingent Deferred Sales Charge Waivers" below apply to
redemptions of Class A shares upon which a contingent deferred sales charge
would otherwise be imposed. For federal income tax purposes, the amount of the
contingent deferred sales charge will reduce the gain or increase the loss, as
the case may be, realized on a redemption. The amount of any contingent deferred
sales charge will be paid to GT Global.
 
                           PURCHASING CLASS B SHARES
 
The Fund's public offering price for Class B shares is the next determined net
asset value per share. See "Calculation of Net Asset Value." No initial sales
charge is imposed. A contingent deferred sales charge, however, is imposed on
certain redemptions of Class B shares. Because the Class B shares are sold
without an initial sales charge, the Fund receives the full amount of the
investor's purchase payment. Class B shares may not be purchased for a Savings
Incentive Match Plan for Employees IRA ("SIMPLE IRA") for which a designated
financial institution was selected by the employer on Form 5305-SIMPLE. However,
Class B shares may be purchased for SIMPLE IRAs using Form 5304-SIMPLE. In
addition, Class A shares may be purchased for all SIMPLE IRAs.
 
Class B shares will not be subject to a contingent deferred sales charge to the
extent that the value of such shares represents: (1) reinvestment of dividends
or other distributions or (2) shares redeemed more than six years after their
purchase. Redemptions of most other Class B shares will be subject to a
contingent deferred sales charge. See "Contingent Deferred Sales Charge
Waivers." The amount of any applicable contingent deferred sales charge will be
calculated by multiplying the lesser of the original purchase price or the net
asset value of such shares at the time of redemption by the applicable
percentage shown in the table below:

In determining whether a contingent deferred sales charge is applicable, it will
be assumed that the redemption is made first of shares acquired pursuant to the
reinvestment of dividends and other distributions; then of shares purchased
seven years or more prior to the redemption; and finally of shares held for the
longest period of time within the applicable six-year period. For shares
acquired in an exchange, the length of the holding period will be measured from
the date of original purchase.
 
For example, assume an investor purchased 100 shares at $10 per share for a cost
of $1,000. Subsequently, the shareholder acquired 15 additional shares through
dividend reinvestment. During the second year after the purchase the investor
decided to redeem $500 of his or her investment. Assuming at the time of the
redemption a net asset value of $11 per share, the value of the investor's
shares would be $1,265 (115 shares at $11 per share). The contingent deferred
sales charge would not be applied to the value of the reinvested dividend
shares. Therefore, the 15 shares currently valued at $165 would be redeemed
without a contingent deferred sales charge. The number of shares needed to fund
the remaining $335 of the redemption would equal 30.455. Using the lower of cost
or market price to determine the contingent deferred sales charge the original
purchase price of $10 per share would be used. The contingent deferred sales
charge calculation would therefore be 30.455 shares times $10 per share at a
contingent deferred sales charge rate of 4% (the applicable rate in the second
year after purchase) for a total contingent deferred sales charge of $12.18.
 
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 contingent deferred sales charge described above, to
a contingent deferred sales charge equivalent to the early withdrawal charge on
the common stock of the Floating Rate Fund. The purchase of Class B shares
 
                               Prospectus Page 16
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
will be deemed to have occurred at the time of the initial purchase of the
Floating Rate Fund's common stock.
 
For federal income tax purposes, the amount of the contingent deferred sales
charge will reduce the gain or increase the loss, as the case may be, realized
on a redemption. The amount of any contingent deferred sales charge will be paid
to GT Global.

                              SALES CHARGE WAIVERS
 
The contingent deferred sales charge will be waived for (1) exchanges, as
described below; (2) redemptions in connection with the Fund's systematic
withdrawal plan not in excess of 12% of the value of the account annually; (3)
total or partial redemptions made within one year following the death or
disability of a shareholder; (4) 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;
(5) total or partial redemptions resulting from a distribution following
retirement in the case of a tax-qualified employer-sponsored retirement plan;
(6) when a redemption results from a tax-free return of an excess contribution
pursuant to Section 408(d)(4) or (5) of the Code or from the death or disability
of the employee; (7) a one-time reinvestment in Class B shares of the Fund
within 180 days of a prior redemption; and (8) redemptions pursuant to the
Fund's right to liquidate a shareholder's account involuntarily; (9) 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; (10) redemptions made in connection with participant-directed
exchanges between options in an employer-sponsored benefit plan; (11)
redemptions made for the purpose of providing cash to fund a loan to a
participant in a tax-qualified retirement plan; (12) redemptions made in
connection with a distribution from any retirement plan or account that is
permitted in accordance with the provisions of Section 72(t)(2) of the Code, and
the regulations promulgated thereunder; (13) redemptions made in connection with
a distribution from any retirement plan or account that involves the return of
an excess deferral amount pursuant to Section 401(k)(8) or Section 402(g)(2) of
the Code or the return of excess aggregate contributions pursuant to Section
401(m)(6) of the Code; (14) redemptions made in connection with a distribution
(from a qualified profit-sharing or stock bonus plan described in Section 401(k)
of the Code) to a participant or beneficiary under Section 401(k)(2)(B)(IV) of
the Code upon hardship of the covered employee (determined pursuant to Treasury
Regulation Section 1.401(k)-1(d)(2)); and (15) redemptions made by or for the
benefit of certain states, counties or cities, or any instrumentalities,
departments or authorities thereof, where such entities are prohibited or
limited by applicable law from paying a sales charge or commission.
 
            PROGRAMS APPLICABLE TO CLASS A SHARES AND CLASS B SHARES
 
   
AUTOMATIC INVESTMENT PLAN. Investors may purchase either Class A or Class B
shares of the Fund through the GT Global Automatic Investment Plan. Under this
Plan, an amount specified by the shareholder of $100 or more ($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.
Participants in the Automatic Investment Plan should not elect to receive
dividends or other distributions from the Fund in cash. A sales charge will be
applied to each automatic monthly purchase of Class A Fund shares in an amount
determined in accordance with the Right of Accumulation privilege described
above. 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
GT Global for more information.
    
 
DOLLAR COST AVERAGING PROGRAM. Investors may purchase either Class A or Class B
shares of the Fund through the GT Global Dollar Cost Averaging Program whereby a
shareholder invests the same dollar amount each month. Accordingly, the investor
purchases more shares when the Fund's net asset value is relatively low and
fewer shares when the Fund's net asset value is relatively high. This can result
in a lower average cost-per-share than if the shareholder followed a less
systematic approach. Dollar cost averaging does not assure a profit and does not
protect against loss in declining markets. Because such a program involves
 
                               Prospectus Page 17
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
continuous investment in securities regardless of fluctuating price levels of
such securities, investors should consider their financial ability to continue
purchases when prices are declining.
 
   
A participant in the GT Global Dollar Cost Averaging Program first designates
the size of his or her monthly investment in the Fund ("Monthly Investment")
after participation in the Program begins. The Monthly Investment must be at
least $1,000. The investor then will make an initial investment of at least
$10,000 in the GT Global Dollar Fund. Thereafter, each month an amount equal to
the specified Monthly Investment automatically will be redeemed from the GT
Global Dollar Fund and invested in Fund shares. A sales charge will be applied
to each automatic monthly purchase of Class A shares of the Fund in an amount
determined in accordance with the Right of Accumulation privilege described
above. Investors should contact their Financial Institution or GT Global 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 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, Other
Distributions 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 GT Global 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. Shareholders participating in
the Program may also participate in the Right of Accumulation, Letter of Intent,
and Dollar Cost Averaging programs. Certain Financial Institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their Financial Institution or GT Global for more information.

                             HOW TO MAKE EXCHANGES
 
- --------------------------------------------------------------------------------
 
Shares of the Fund may be exchanged for shares of the same class 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." In addition to the
Fund, the GT Global Mutual Funds currently include:
 
   -- GT GLOBAL AMERICA MID CAP GROWTH FUND
   -- GT GLOBAL AMERICA SMALL CAP GROWTH FUND
   -- GT GLOBAL AMERICA VALUE FUND
   -- GT GLOBAL CONSUMER PRODUCTS AND
       SERVICES FUND
   -- GT GLOBAL DEVELOPING MARKETS FUND
   -- GT GLOBAL DOLLAR FUND
   -- GT GLOBAL EMERGING MARKETS FUND
   -- GT GLOBAL EUROPE GROWTH FUND
   -- GT GLOBAL FINANCIAL SERVICES FUND
   -- GT GLOBAL GOVERNMENT INCOME FUND
   -- GT GLOBAL HEALTH CARE FUND
   -- GT GLOBAL HIGH INCOME FUND
   -- GT GLOBAL INFRASTRUCTURE FUND
   -- GT GLOBAL INTERNATIONAL GROWTH FUND
   -- GT GLOBAL JAPAN GROWTH FUND
   -- GT GLOBAL LATIN AMERICA GROWTH FUND
   -- GT GLOBAL NATURAL RESOURCES FUND
   -- GT GLOBAL NEW DIMENSION FUND
   -- GT GLOBAL NEW PACIFIC GROWTH FUND
   -- GT GLOBAL STRATEGIC INCOME FUND
   -- GT GLOBAL TELECOMMUNICATIONS FUND
   -- GT GLOBAL WORLDWIDE GROWTH FUND
 
Up to four exchanges each year may be made without charge. A $7.50 service
charge will be imposed on each subsequent exchange. 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
calculated on 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 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 instructions to the
shareholder's Financial Institution or the Transfer Agent by telephone at the
appropriate toll-free number provided in the Shareholder Account Manual.
Exchange orders will be accepted by telephone provided that the exchange
involves only uncertificated shares on deposit in the shareholder's account or
for which certificates previously have been deposited. Shareholders
automatically have telephone privileges to authorize exchanges. The Fund, GT
Global 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 GT Global reserve the right to refuse
purchase orders and exchanges by any person or group, if, in the Manager'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 GT Global reserve the right to
refuse purchase orders and exchanges by any person or group if, in the Manager'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, each GT Global Mutual Fund and GT Global reserve
the right to reject any purchase order.

                              HOW TO REDEEM SHARES
 
- --------------------------------------------------------------------------------
 
Fund shares may be redeemed at their net asset value (subject to any applicable
contingent deferred sales charge for Class B shares or, in limited
circumstances, Class A shares) and redemption proceeds will be sent within seven
days of the execution of a redemption request. If a redeeming shareholder owns
more than one class of shares, the Shareholder must specify the class of shares
to be redeemed.
 
   
REDEMPTIONS THROUGH FINANCIAL INSTITUTIONS. Shareholders with accounts at
Financial Institutions which sell shares of the Fund may submit redemption
requests to such Financial Institutions. If the shares are held in the name of
the Financial Institution, the redemption must be made through the Financial
Institution. Financial Institutions may honor a redemption request either by
repurchasing shares from a redeeming shareholder at the net asset value next
determined after the Financial Institution receives the request or, as described
below, by forwarding such requests to the Transfer Agent (see "How to Redeem
Shares -- Redemptions Through the Transfer Agent"). Redemption proceeds normally
will be paid by check or, if offered by the Financial Institution, credited to
the shareholder's account at the Financial Institution at the election of the
shareholder. Financial Institutions may impose a service charge for handling
redemption transactions placed through them and may have other requirements
concerning redemptions. Accordingly, shareholders should contact their Financial
Institution for more details.
    
 
   
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 or, in limited circumstances, Class A 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 within 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 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.
 
                               Prospectus Page 20
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
Shareholders who hold certificates for shares may not redeem by telephone.
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, GT Global 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. Redemptions of shares for which certificates have been issued must
be accompanied by properly endorsed share certificates.
 
   
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 proceeds from monthly, quarterly or
annual redemptions of Fund shares with respect to either Class A or Class B
shares. No contingent deferred sales charge 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 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. With respect to Class A shares, participation in the
Systematic Withdrawal Plan concurrent with purchases of Class A shares of the
Fund may be disadvantageous to investors because of the sales charges involved
and possible tax implications, and therefore is discouraged. In addition,
shareholders who participate in the Systematic Withdrawal Plan should not elect
to reinvest dividends or other distributions in additional Fund shares.
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 as to 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 in writing 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 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).

                         GT GLOBAL GROWTH & INCOME FUND
 
                         CALCULATION OF NET ASSET VALUE
 
- --------------------------------------------------------------------------------
 
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. The
Fund's net asset value per share is computed by determining the value of its
total assets (the securities it holds plus any cash or other assets, including
the interest accrued but not yet received), subtracting all of its liabilities
(including accrued expenses), and dividing the result by the total number of
shares outstanding at such time. Net asset value is determined separately for
each class of the Fund.
 
Equity securities are valued at the last sale price on the exchange or in the
over-the-counter market in which such securities are primarily traded, as of the
close of business on the day the securities are being valued or, lacking any
sales, at the last available bid price. Long-term obligations are valued at the
mean of representative quoted bid and asked prices for such securities or, if
such prices are not available, at prices for securities of comparable maturity,
quality and type; however, when the Manager deems it appropriate, prices
obtained from a bond pricing service will be used. Short-term debt investments
are amortized to maturity based on their cost, adjusted for foreign exchange
translation and market fluctuations, provided such valuations represent fair
value. When market quotations for futures and options positions held by the Fund
are readily available, those positions are valued based upon such quotations.
 
Securities and other assets for which market quotations are not readily
available are valued at fair value determined in good faith by or under the
direction of the Company's Board of Directors. Securities and other assets
quoted in foreign currencies are valued in U.S. dollars based on the prevailing
exchange rates on that day.
 
The Fund's portfolio securities, from time to time, may be listed primarily on
foreign exchanges or over-the-counter dealer markets that trade on days when the
NYSE is closed (such as a Saturday). As a result, the net asset value of the
Fund may be significantly affected by such trading on days when shareholders
cannot purchase or redeem shares of the Fund.
 
The different service and distribution fees borne by each class of shares of the
Fund will result in different net asset values. The per share net asset value of
the Class B shares of the Fund generally will be lower than that of the Class A
shares of that Fund because of the higher service and distribution fees borne by
the Class B shares. The per share net asset value of the Advisor Class shares of
the Fund generally will be higher than that of the Class A and Class B shares of
the Fund because of the absence of any service and distribution fees applicable
to the Advisor Class shares. It is expected, however, that the net asset value
per share of the classes will tend to converge immediately after the payment of
dividends, which will differ by approximately the amount of the service and
distribution fee accrual differential among the classes.

                         DIVIDENDS, OTHER DISTRIBUTIONS
                          AND FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. The Fund declares and pays quarterly
dividends from its net investment income, if any, which includes dividends,
accrued interest and earned discount (including both original issue and market
discounts) less applicable expenses. The Fund also annually distributes
substantially all of its realized net short-term capital gain (the excess of
short-term capital gains over short-term capital losses), net capital gain (the
excess of net long-term capital gain over net short-term loss) and net gains
from foreign currency transactions, if any. The Fund may make an additional
dividend or other distribution
 
                               Prospectus Page 23
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
if necessary to avoid a 4% excise tax on certain undistributed income and gain.
 
Dividends and other distributions 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 income dividends on Class B shares will be lower than the per share income
dividends on Class A shares as a result of the higher service and distribution
fees applicable to Class B shares; and the per share income dividends on both
such classes of shares will be lower than the per share income dividends on the
Advisor Class shares as a result of the absence of any service and distribution
fees applicable to Advisor Class shares. SHAREHOLDERS MAY ELECT:
 
/ / to have all dividends and other distributions automatically reinvested in
    additional Fund shares of the distributing class (or in shares of the
    corresponding class of other GT Global Mutual Funds); or
 
/ / to receive dividends in cash and have other distributions automatically
    reinvested in additional Fund shares of the distributing class (or in shares
    of the corresponding class of other GT Global Mutual Funds); or
 
/ / to receive other distributions in cash and have dividends automatically
    reinvested in additional Fund shares of the distributing class (or in shares
    of the corresponding class of other GT Global Mutual Funds); or
 
/ / to receive dividends and other distributions in cash.
 
Automatic reinvestments in additional shares are made at net asset value without
imposition of a sales charge. IF NO ELECTION IS MADE BY A SHAREHOLDER, ALL
DIVIDENDS AND OTHER DISTRIBUTIONS WILL BE AUTOMATICALLY REINVESTED IN ADDITIONAL
FUND SHARES OF THE DISTRIBUTING CLASS. Reinvestments in another GT Global Mutual
Fund may only be directed to an account with the identical shareholder
registration and account number. These elections may be changed by a shareholder
at any time; to be effective with respect to a distribution, the shareholder or
the shareholder's broker must contact the Transfer Agent by mail or telephone at
least 15 Business Days prior to the payment date. THE FEDERAL INCOME TAX
CONSEQUENCES OF DIVIDENDS AND OTHER DISTRIBUTIONS ARE THE SAME WHETHER THEY ARE
RECEIVED IN CASH OR REINVESTED IN ADDITIONAL SHARES.
 
Any dividend or other distribution paid by the Fund has the effect of reducing
the net asset value per share on the ex-distribution date by the amount thereof.
Therefore, a dividend or other distribution paid shortly after a purchase of
shares would represent, in substance, a return of capital to the shareholder (to
the extent the distribution is paid on the shares so purchased), even though
subject to income tax, as discussed below.
 
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
generally of net investment income, net gains from certain foreign currency
transactions and net short-term capital gain) and net capital gain (i.e., the
excess of net long-term capital gain over net short-term capital loss) that it
distributes to its shareholders.
 
Dividends from the Fund's investment company taxable income (whether paid in
cash or reinvested in additional shares) are taxable to its shareholders as
ordinary income to the extent of its earnings and profits. Distributions of the
Fund's net capital gain, when designated as such, are taxable to its
shareholders as long-term capital gains, regardless of how long they have held
their Fund shares and whether paid in cash or reinvested in additional shares.
 
Under the Taxpayer Relief Act of 1997, different maximum tax rates apply to a
noncorporate taxpayer's net capital gain depending on the taxpayer's holding
period and marginal rate of federal income tax -- generally, 28% for gain
recognized on securities held for more than one year but not more than 18 months
and 20% (10% for taxpayers in the 15% marginal tax bracket) for gain recognized
on securities held for more than 18 months. Pursuant to an Internal Revenue
Service notice, the Fund may divide each net capital gain distribution into a
28% rate gain distribution and a 20% rate gain distribution (in accordance with
the Fund's holding periods for the securities it sold that generated the
distributed gain) and its shareholders must treat those portions accordingly.
 
The Fund provides federal tax information to its shareholders annually,
including information about dividends and capital gain distributions paid during
the preceding year and, under certain circumstances, the shareholders'
respective shares of any foreign taxes paid (directly or indirectly) by the
Fund, in which event each shareholder would be required to include in his or her
gross income his or her pro rata share of those taxes but might be entitled to
claim a credit or deduction for them. The information regarding capital gain
distributions
 
                               Prospectus Page 24
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
designates the portions thereof subject to the different maximum rates of tax
applicable to noncorporate taxpayers' net capital gain indicated above.
 
The Fund must withhold 31% from dividends, capital gain distributions and
redemption proceeds payable to any individuals and certain other noncorporate
shareholders who 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. Withholding at that rate also is required from dividends and capital gain
distributions payable to such shareholders who otherwise are subject to backup
withholding. 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.
 
A redemption of Fund shares may result in taxable gain or loss to the redeeming
shareholder, depending upon whether the redemption proceeds are more or less
than the shareholder's adjusted basis for the redeemed shares (which normally
includes any initial sales charge paid on Class A shares). An exchange of Fund
shares for shares of another GT Global Mutual Fund generally will have similar
tax consequences. However, special tax rules apply when a shareholder (1)
disposes of Class A shares of the Fund through a redemption or exchange within
90 days after purchase and (2) subsequently acquires Class A shares of the Fund
or of any other GT Global Mutual Fund on which an initial sales charge normally
is imposed without paying that sales charge due to the reinstatement privilege
or exchange privilege. In these cases, any gain on the disposition of the
original Class A shares will be increased, or loss decreased, by the amount of
the sales charge paid when those shares were acquired, and that amount will
increase the adjusted basis of the shares subsequently acquired. In addition, if
Fund shares are purchased within 30 days before or after redeeming other Fund
shares (regardless of class) at a loss, all or a part of the loss will not be
deductible and instead will increase the basis of the newly purchased shares.
 
The foregoing is only a summary of some of the important federal tax
considerations generally affecting the Fund and its shareholders. See "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 therefore are urged to consult their
tax advisers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
The Company's Board of Directors has overall responsibility for the operation of
the Fund. Pursuant to such responsibility, the Board has approved contracts with
various financial organizations to provide, among other things, day to day
management services required by the Fund. See "Directors and Executive Officers"
in the Statement of Additional Information for a complete description of the
Directors of the Company.
 
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by Chancellor LGT
Asset Management, Inc. (the "Manager") as the Fund's investment manager and
administrator include, but are not limited to, determining the composition of
the Fund's portfolio and placing orders to buy, sell or hold particular
securities; furnishing corporate officers and clerical staff; providing office
space, services and equipment; and supervising all matters relating to the
Fund's operation. For these services, the Fund pays the Manager investment
management and administration fees, computed daily and paid monthly, based on
the average daily net assets, at the annualized rate of .975% on the first $500
million, .95% on the next $500 million, .925% on the next $500 million and .90%
on amounts thereafter. This rate is higher than that paid by most mutual funds.
The Manager and GT Global have undertaken to limit the Fund's expenses
(exclusive of brokerage commissions, taxes, interest and extraordinary expenses)
to the annual rate of 1.75% and 2.40% of the average daily net assets of the
Fund's Class A and
 
                               Prospectus Page 25
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
Class B shares, respectively. This undertaking may be changed or eliminated in
the future.
 
The Manager also serves as the Fund's pricing and accounting agent. For these
services the Manager 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 each Fund's average
daily net assets.
 
The Manager provides investment management and/or administration services to the
GT Global Funds. The Manager and its worldwide asset management affiliates have
provided investment management and/or administration services to institutional,
corporate and individual clients around the world since 1969. The U.S. offices
of the Manager are located at 50 California Street, 27th Floor, San Francisco,
CA 94111 and 1166 Avenue of the Americas, New York, NY 10036.
 
   
The Manager and its worldwide affiliates, including LGT Bank in Liechtenstein,
compose Liechtenstein Global Trust ("LGT"). LGT is a provider of global asset
management and private banking products and services to individual and
institutional investors. LGT is controlled by the Prince of Liechtenstein
Foundation, which serves as a parent organization for the various business
enterprises of the Princely Family of Liechtenstein. The principal business
address of the Prince of Liechtenstein Foundation is Herrengasse 12, FL-9490,
Vaduz, Liechtenstein.
    
 
   
On January 30, 1998, LGT entered into an agreement with AMVESCAP PLC
("AMVESCAP") pursuant to which AMVESCAP will acquire LGT's Asset Management
Division, which includes the Manager. AMVESCAP is a holding company formed in
1997 by the merger of INVESCO PLC and A I M Management Group Inc. Consummation
of the transaction is subject to a number of contingencies, including regulatory
approvals. Because the transaction would constitute an assignment of the
Company's investment management agreement under the Investment Company Act of
1940 (and, therefore, a termination of such agreement), it is anticipated that
the approval of the Company's Board of Directors and the Company's shareholders
of new investment management arrangements will be sought. The Manager
anticipates that the transaction will be presented for shareholder approval and
anticipates that the transaction will close on or about May 31, 1998.
    
 
   
As of December 31, 1997, the Manager and its worldwide asset management
affiliates managed approximately $54 billion in assets. In the United States, as
of December 31, 1997, the Manager managed or administered approximately $8
billion of assets of GT Global Funds. As of December 31, 1997, assets entrusted
to LGT totaled approximately $79 billion.
    
 
   
In addition to the investment resources of its San Francisco and New York
offices, the Manager draws upon the expertise, personnel, data and systems of
other offices of Liechtenstein Global Trust, including investment offices in
Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo and Toronto. In managing
the GT Global Funds, the Manager employs a team approach, taking advantage of
its investment resources around the world in seeking each Fund's investment
objective.

of the Fund are as follows:

In placing securities orders for the Fund's portfolio transactions, the Manager
seeks to obtain the best net results. Consistent with its obligation to obtain
the best net results, the Manager may consider a broker/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. GT Global is the distributor of the Fund's Class A
and Class B shares. GT Global is a subsidiary of Liechtenstein Global Trust with
offices at 50 California Street, 27th Floor, San Francisco, CA 94111. As
distributor, GT Global collects the sales charges imposed on purchases of Class
A shares and any contingent deferred sales charges that may be imposed on
certain redemptions of Class A or Class B shares. GT Global reallows a portion
of the sales charge on Class A shares to broker/dealers that have sold such
shares in accordance with the schedule set forth above under "How to Invest." GT
Global also pays a commission equal to 4.00% of the amount invested to
broker/dealers who sell Class B shares. From time to time, GT Global may pay
commissions in excess of these amounts. Commissions are not paid on exchanges or
certain reinvestments in Class B shares. In addition, with respect to both
classes of shares, GT Global makes ongoing payments to broker/dealers for
distribution and service activities in accordance with the Rule 12b-1 plans
described below.
 
GT Global, 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 brokers 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, GT
Global makes ongoing payments to brokerage firms, financial institutions
(including banks) and others that facilitate the administration and servicing of
shareholder accounts.
 
Under a plan of distribution adopted by the Company's Board of Directors
pursuant to Rule 12b-1 under the 1940 Act, with respect to the Fund's Class A
shares ("Class A Plan"), the Fund may pay GT Global a service fee at the
annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class A shares for its expenditures incurred in servicing and maintaining
shareholder accounts, and may pay GT Global a distribution fee at the annualized
rate of up to 0.35% of the average daily net assets of the Fund's Class A
shares, less any amounts paid by the Fund as the aforementioned service fee for
its expenditures incurred in providing services as distributor. All expenses for
which GT Global is reimbursed under the Class A Plan will have been incurred
within one year of such reimbursement.
 
Pursuant to a separate plan of distribution adopted with respect to the Fund's
Class B shares ("Class B Plan"), the Fund may pay GT Global a service fee at the
annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class B shares for its expenditures incurred in servicing and maintaining
shareholder accounts, and may pay GT Global a distribution fee at the annualized
rate of up to 0.75% of the average daily net assets of the Fund's Class B shares
for its expenditures incurred in providing services as distributor. Expenses
incurred under the Class B Plan in excess of 1.00% annually may be carried
forward for reimbursement in subsequent years as long as that Plan continues in
effect. As of October 31, 1997, unreimbursed distribution expenses amounted to
approximately $695,000 (equivalent to approximately .15% of the Fund's net
assets).
 
GT Global's service and distribution expenses covered by the Plans include the
payment of ongoing commissions; the cost of any additional compensation paid by
GT Global to brokers/dealers; the costs of printing and mailing to prospective
investors prospectuses and other materials relating to the Fund; the costs of
developing, printing, distributing and publishing advertisements and other sales
literature; and allocated costs relating to GT Global's distribution activities,
including, among other things, employee salaries, bonuses and other overhead
expenses. In addition, its expenses covered by the Class B Plan include payment
of initial sales commissions to broker/dealers and interest on any unreimbursed
amounts carried forward thereunder.
 
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, GT Global intends to
engage banks (if at all) only to perform administrative and shareholder
servicing functions. If a bank

                         GT GLOBAL GROWTH & INCOME FUND
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.

CONFIRMATIONS AND REPORTS TO SHAREHOLDERS. Each time a transaction is made that
affects a shareholder's account in the Fund, the shareholder will receive from
the Transfer Agent a confirmation statement reflecting the transaction.
Confirmations for transactions effected pursuant to the Fund's Automatic
Investment Plan, Systematic Withdrawal Plan, and automatic dividend reinvestment
program may be provided quarterly. Shortly after the end of the Fund's fiscal
year on October 31 and fiscal half-year on April 30 of each year, shareholders
receive an annual and semiannual report, respectively. In addition, the federal
income tax status of distributions made by the Fund to 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 Maryland corporation
on October 29, 1987. From time to time, the Company has established and may
continue to establish other funds, each corresponding to a distinct investment
portfolio and a distinct series of the Company's common stock. Shares of the
Fund are entitled to one vote per share (with proportional voting for fractional
shares) and are freely transferable. Shareholders have no preemptive or
conversion rights.
 
On any matter submitted to a vote of shareholders, shares of the Fund will be
voted by the Fund's shareholders individually when the matter affects the
specific interest of the Fund only, such as approval of its investment
management arrangements. In addition, each class of shares of the Fund has
exclusive voting rights with respect to its distribution plan. The shares of the
Fund and the Company's other funds will be voted in the aggregate on other
matters, such as the election of Directors 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
Directors holding office had been elected by shareholders. Directors 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
Directors can elect all the Directors. A Director 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
Director or for any other purpose. The 1940 Act requires the Company to assist
shareholders in calling such a meeting.
 
Pursuant to the Company's Articles of Incorporation, it may issue six billion
shares. Of this number, 300 million shares have been classified as shares of the
Fund; 100 million shares have been classified as Class A shares, 100 million
shares have been classified as Class B shares, and 100 million shares have been
classified as Advisor Class shares. This amount may be increased from time to
time in the discretion of the Board of Directors. Each share of the Fund
represents an interest in the Fund only, has a par value of $0.0001 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 Directors. Each Class A, Class B and Advisor
Class share of the Fund is equal in earnings, assets and voting privileges,
except as noted above, and each class bears the expenses, if any, related to the
distribution of its shares. Shares of the Fund, when issued, are fully paid and
nonassessable.

SHAREHOLDER INQUIRIES. Shareholder inquiries may be made by calling the Fund
toll-free at (800) 223-2138 or by writing to the Fund at 50 California Street,

PERFORMANCE INFORMATION. The Fund, from time to time, may include information on
its investment results and/or comparisons of its investment results to various
unmanaged indices or results of other mutual funds or groups of mutual funds in
advertisements, sales literature or reports furnished to present or prospective
shareholders.
 
In such materials, 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 of the end of a
shorter period corresponding to the life of the Fund. Standardized Return
assumes reinvestment of all dividends and other 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 total return (e.g., income and capital appreciation or
depreciation); it assumes reinvestment of all dividends and other 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 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.
 
The Fund's annual report contains additional information with respect to its
performance. The annual report is available to investors upon request and free
of charge.

<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
                            INVESTMENT OBJECTIVE AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVE
The  investment objective of the Fund is long-term capital appreciation together
with current  income. The  Fund seeks  its objective  by investing  in a  global
portfolio of both equity securities and debt obligations allocated among diverse
international markets.
 
SELECTION OF EQUITY INVESTMENTS
For  investment  purposes, an  issuer is  typically considered  as located  in a
particular country  if it  (a) is  incorporated under  the laws  of or  has  its
principal  office in that country, or (b) it normally derives 50% or more of its
total revenue from  business in that  country. However, these  are not  absolute
requirements,  and certain  companies incorporated  in a  particular country and
considered by the  Manager to be  located in that  country may have  substantial
off-shore  operations or subsidiaries and/or export  sales exceeding in size the
assets or sales in that country.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
   
The Fund  may  invest  in  the securities  of  investment  companies  (including
investment  vehicles  or  companies advised  by  the Manager  or  its affiliates
("Affiliated Funds")) within the limits of  the Investment Company Act of  1940,
as  amended ("1940 Act"). These limitations  currently provide that, in general,
the Fund may purchase shares of a closed-end investment company unless (a)  such
a  purchase would cause the Fund to own  in the aggregate more than 3 percent of
the total  outstanding voting  stock of  the investment  company or  (b) such  a
purchase  would cause the Fund  to have more than 5  percent of its total assets
invested in the investment company or more  than 10 percent of its total  assets
invested  in an aggregate  of all such investment  companies. Investment in such
investment companies may also involve the payment of substantial premiums  above
the  value of such companies' portfolio securities.  The Fund does not intend to
invest in such investment companies unless, in the judgment of the Manager,  the
potential  benefits of  such investments justify  the payment  of any applicable
premiums. The return on such securities will be reduced by operating expenses of
such companies including payments to the investment managers of those investment
companies. With respect to investments  in Affiliated Funds, the Manager  waives
its  advisory fee to the extent  that such fees are based  on assets of the Fund
invested in Affiliated Funds.
    
 
DEPOSITORY RECEIPTS
   
The Fund may hold equity securities of  foreign issuers in the form of  American
Depository  Receipts  ("ADRs"),  American  Depository  Shares  ("ADSs"),  Global
Depository Receipts ("GDRs") and European Depository Receipts ("EDRs"), or other
securities convertible into securities of eligible issuers. These securities may
not necessarily be denominated in the same currency as the securities for  which
they may be exchanged. ADRs and ADSs typically are issued by an American bank or
trust  company  and  evidence ownership  of  underlying securities  issued  by a
foreign corporation.  EDRs,  which  are sometimes  referred  to  as  Continental
Depository  Receipts ("CDRs"), are  issued in Europe  typically by foreign banks
and trust  companies  and  evidence  ownership of  either  foreign  or  domestic
securities.  GDRs  are similar  to  EDRs and  are  designed for  use  in several
international financial markets. Generally, ADRs and ADSs in registered form are
designed for use in United States securities markets and EDRs in bearer form are
designed for use  in European  securities markets.  For purposes  of the  Fund's
investment policies, the Fund's investments in ADRs, ADSs, GDRs and EDRs will be
deemed  to be  investments in the  equity securities  representing securities of
foreign issuers into which they may be converted.
    
 
ADR facilities may be established as either "unsponsored" or "sponsored."  While
ADRs  issued under these two  types of facilities are  in some respects similar,
there are distinctions between  them relating to the  rights and obligations  of
ADR holders and the practices of market participants. A depository may establish
an  unsponsored  facility  without  participation by  (or  even  necessarily the
acquiescence of) the issuer of the deposited securities, although typically  the
depository  requests a  letter of  non-objection from  such issuer  prior to the
establishment of the facility.  Holders of unsponsored  ADRs generally bear  all
the  costs  of such  facilities. The  depository usually  charges fees  upon the
deposit and withdrawal of the deposited securities, the conversion of  dividends
into   U.S.  dollars,  the  disposition   of  non-cash  distributions,  and  the
performance of  other  services.  The  depository  of  an  unsponsored  facility
frequently  is  under  no obligation  to  distribute  shareholder communications
received from the issuer of the  deposited securities or to pass-through  voting
rights  to ADR  holders in  respect of  the deposited  securities. Sponsored ADR
facilities are created in generally the same manner as
 
                   Statement of Additional Information Page 2
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
unsponsored facilities,  except  that the  issuer  of the  deposited  securities
enters  into a deposit agreement with the depository. The deposit agreement sets
out the rights and  responsibilities of the issuer,  the depository and the  ADR
holders.  With  sponsored facilities,  the  issuer of  the  deposited securities
generally will bear some of the costs relating to the facility (such as dividend
payment fees of the depository), although  ADR holders continue to bear  certain
other  costs (such  as deposit  and withdrawal  fees). Under  the terms  of most
sponsored arrangements, depositories agree to distribute notices of  shareholder
meetings  and voting instructions, and to provide shareholder communications and
other information  to the  ADR  holders at  the request  of  the issuer  of  the
deposited  securities. The  Fund may  invest in  both sponsored  and unsponsored
ADRs.
 
WARRANTS OR RIGHTS
Warrants or  rights  may  be acquired  by  the  Fund in  connection  with  other
securities  or separately and provide  the Fund with the  right to purchase at a
later date other securities of the issuer.
 
LENDING OF PORTFOLIO SECURITIES
For the purpose of realizing additional income, the Fund may make secured  loans
of  portfolio securities  amounting to  not more than  30% of  its total assets.
Securities loans are made to broker/dealers or institutional investors  pursuant
to  agreements requiring that the loans continuously be secured by collateral at
least equal at all times  to the value of the  securities lent plus any  accrued
interest,  "marked to  market" on  a daily  basis. The  Fund may  pay reasonable
administrative and custodial fees  in connection with  loans of its  securities.
While  the securities loan is outstanding, the Fund will continue to receive the
equivalent of the interest or dividends paid by the issuer on the securities, as
well as interest on the investment of the collateral or a fee from the borrower.
The Fund will have a  right to call each loan  and obtain the securities  within
the  stated settlement period. The  Fund will not have  the right to vote equity
securities while they are lent, but it may call in a loan in anticipation of any
important vote. Loans will be made only to firms deemed by the Manager to be  of
good  standing and will not be made unless,  in the judgment of the Manager, the
consideration to be earned from such loans would justify the risk.
 
COMMERCIAL BANK OBLIGATIONS
For the  purposes  of  the  Fund's investment  policies  with  respect  to  bank
obligations,  obligations of foreign branches of U.S. banks and of foreign banks
are obligations of the issuing bank and may be general obligations of the parent
bank. Such  obligations, however,  may be  limited by  the terms  of a  specific
obligation  and  by  government  regulation.  As  with  investment  in  non-U.S.
securities in general,  investments in  the obligations of  foreign branches  of
U.S.  banks and of foreign  banks may subject the  Fund to investment risks that
are different  in some  respects from  those of  investments in  obligations  of
domestic  issuers. Although the  Fund typically will  acquire obligations issued
and supported by the credit of U.S. or foreign banks having total assets at  the
time  of purchase  in excess  of $1 billion,  this $1  billion figure  is not an
investment policy or restriction  of the Fund. For  the purposes of  calculation
with  respect to the $1 billion  figure, the assets of a  bank will be deemed to
include the assets of its U.S. and non-U.S. branches.
 
REPURCHASE AGREEMENTS
A repurchase agreement is a transaction  in which 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 Manager  to
present  minimum credit risks  in accordance with  guidelines established by the
Company's  Board  of  Directors.  The  Manager  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  the U.S. Bankruptcy  Code that would  allow it immediately  to resell the
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.
 
                   Statement of Additional Information Page 3
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
The Fund's borrowings will not exceed 33 1/3% of the Fund's total assets,  i.e.,
the  Fund's total assets at all times will  equal at least 300% of the amount of
outstanding borrowings.  If  market fluctuations  in  the value  of  the  Fund's
portfolio  holdings or other factors cause the  ratio of the Fund's total assets
to outstanding  borrowings to  fall  below 300%,  within three  days  (excluding
Sundays  and holidays) of such event the  Fund may be required to sell portfolio
securities to restore the  300% asset coverage, even  though from an  investment
standpoint  such sales might be disadvantageous. The  Fund also may borrow up to
5% of its total assets  for temporary or emergency  purposes other than to  meet
redemptions.  Any borrowing  by the  Fund may  cause greater  fluctuation in the
value of its shares than would be the case if the Fund did not borrow.
 
The Fund's fundamental investment  limitations permit the  Fund to borrow  money
for leveraging purposes. The Fund, however, currently is prohibited, pursuant to
a  non-fundamental investment policy, from borrowing  money in order to purchase
securities. Nevertheless, this policy may be changed in the future by a vote  of
a  majority of the Company's Board of Directors. If the Fund employs leverage in
the future, it  would be subject  to certain additional  risks. Use of  leverage
creates  an opportunity for  greater growth of capital  but would exaggerate any
increases or decreases in the Fund's net asset value. When the income and  gains
on securities purchased with the proceeds of borrowings exceed the costs of such
borrowings,  the Fund's  earnings or net  asset value will  increase faster than
otherwise would be the case; conversely, if such income and gains fail to exceed
such costs, the  Fund's earnings or  net asset value  would decline faster  than
would otherwise be the case.
 
The  Fund may  enter into  reverse repurchase  agreements. A  reverse repurchase
agreement is a borrowing transaction in which the Fund transfers possession of a
security to another party, such as a  bank or broker/dealer in return for  cash,
and  agrees to repurchase  the security in  the future at  an agreed upon price,
which includes  an  interest component.  The  Fund  also may  engage  in  "roll"
borrowing  transactions  which involve  the Fund's  sale of  Government National
Mortgage Association certificates or other securities together with a commitment
(for which the Fund may receive a  fee) to purchase similar, but not  identical,
securities  at a future  date. The Fund  will maintain, in  a segregated account
with a custodian, cash or liquid securities in an amount sufficient to cover its
obligations under  "roll" transactions  and reverse  repurchase agreements  with
broker/dealers.  No segregation  is required  for reverse  repurchase agreements
with banks.
 
SHORT SALES
The Fund  may  make  short sales  of  securities,  although it  has  no  current
intention  of doing so. A short sale is  a transaction in which the Fund sells a
security in anticipation that  the market price of  that security will  decline.
The  Fund may  make short  sales (i) as  a form  of hedging  to offset potential
declines in long positions in securities it owns, or anticipates acquiring,  and
(ii)  in order to maintain  portfolio flexibility. The Fund  may only make short
sales "against the box." In this type of short sale, at the time of the sale the
Fund owns the security it has sold short or has the immediate and  unconditional
right to acquire the identical security at no additional cost.
 
In a short sale, the seller does not immediately deliver the securities sold and
does  not receive the proceeds from the sale. To make delivery to the purchaser,
the executing broker borrows  the securities being sold  short on behalf of  the
seller. The seller is said to have a short position in the securities sold until
it  delivers the securities sold, at which  time it receives the proceeds of the
sale. To secure its obligation to  deliver securities sold short, the Fund  will
deposit  in  a  separate account  with  its  custodian an  equal  amount  of the
securities sold short or  securities convertible into  or exchangeable for  such
securities  at no cost. The Fund could  close out a short position by purchasing
and delivering an  equal amount  of the securities  sold short,  rather than  by
delivering  securities already held by the Fund,  because the Fund might want to
continue to  receive  interest  and  dividend  payments  on  securities  in  its
portfolio that are convertible into the securities sold short.
 
   
The  Fund might make  a short sale "against  the box" in  order to hedge against
market risks when the Manager believes that the price of a security may decline,
causing a decline in  the value of a  security owned by the  Fund or a  security
convertible  into or  exchangeable for such  security. In such  case, any future
losses in the  Fund's long position  should be reduced  by a gain  in the  short
position.  Conversely, any gain in the long position should be reduced by a loss
in the short  position. The extent  to which such  gains or losses  in the  long
position  are reduced will depend  upon the amount of  the securities sold short
relative to  the amount  of the  securities the  Fund owns,  either directly  or
indirectly, and, in the case where the Fund owns convertible securities, changes
in  the investment values or conversion  premiums of such securities. There will
be certain additional transaction costs associated with short sales "against the
box," but the  Fund will endeavor  to offset  these costs with  income from  the
investment of the cash proceeds of short sales.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use of options, futures contracts  and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1) Successful  use  of  most  of these  instruments  depends  upon  the
    Manager's  ability  to  predict  movements  of  the  overall  securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Manager is experienced in the
    use of these  instruments, there  can be  no assurance  that any  particular
    strategy adopted will succeed.
 
        (2)  There  might  be  imperfect correlation,  or  even  no correlation,
    between price  movements  of  an  instrument  and  price  movements  of  the
    investments being hedged. For example, if the value of an instrument used in
    a  short hedge  increased by less  than the  decline in value  of the hedged
    investment, the  hedge  would  not  be fully  successful.  Such  a  lack  of
    correlation  might  occur  due to  factors  unrelated  to the  value  of the
    investments being  hedged, such  as speculative  or other  pressures on  the
    markets  in which  the hedging  instrument is  traded. The  effectiveness of
    hedges using hedging  instruments on indices  will depend on  the degree  of
    correlation  between price movements in the index and price movements in the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative  effect of unfavorable price  movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity  for gain by  offsetting the positive  effect of favorable price
    movements in the hedged investments. For  example, if a Fund entered into  a
    short  hedge  because the  Manager projected  a  decline in  the price  of a
    security in the Fund's portfolio, and  the price of that security  increased
    instead,  the gain from that increase might by wholly or partially offset by
    a decline in the price of the hedging instrument. Moreover, if the price  of
    the  hedging instrument declined by  more than the increase  in the price of
    the security, the Fund could  suffer a loss. In  either such case, the  Fund
    would have been in a better position had it not hedged at all.
 
        (4)  As described below, a Fund might  be required to maintain assets as
    "cover," maintain segregated accounts or make margin payments when it  takes
    positions  in  instruments  involving obligations  to  third  parties (I.E.,
    instruments other than purchased options). If the Fund were unable to  close
    out  its positions in such instruments, it  might be required to continue to
    maintain such assets or  accounts or make such  payments until the  position
    expired or matured. The requirements might impair the Fund's ability to sell
    a portfolio security or make an investment at a time when it would otherwise
    be favorable to do so, or require that the Fund sell a portfolio security at
    a  disadvantageous time. The  Fund's ability to  close out a  position in an
    instrument prior to  expiration or maturity  depends on the  existence of  a
    liquid secondary market or, in the absence of such a market, the ability and
    willingness  of the other party to the transaction ("contra party") to enter
    into a  transaction  closing  out  the  position.  Therefore,  there  is  no
    assurance  that any position can  be closed out at a  time and price that is
    favorable to the Fund.
 
WRITING CALL OPTIONS
The Fund may write  (sell) call options on  securities, indices and  currencies.
Call options generally will be written on securities and currencies that, in the
opinion  of the Manager  are not expected to  make any major  price moves in the
near future  but  that,  over  the  long  term,  are  deemed  to  be  attractive
investments for the Fund.
 
A  call option  gives the  holder (buyer)  the right  to purchase  a security or
currency at a specified price (the  exercise price) at any time until  (American
Style)  or on (European Style) a certain  date (the expiration date). So long as
the obligation of the writer of a  call option continues, he may be assigned  an
exercise  notice, requiring him  to deliver the  underlying security or currency
against payment  of the  exercise  price. This  obligation terminates  upon  the
expiration  of the call option, or such earlier time at which the writer effects
a closing  purchase  transaction  by  purchasing an  option  identical  to  that
previously sold.
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on the basis  of investment considerations consistent with  the
Fund's investment objective. When writing a call option, the Fund, in return for
the
 
                   Statement of Additional Information Page 5
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
premium,  gives  up the  opportunity for  profit  from a  price increase  in the
underlying security or currency above the  exercise price, and retains the  risk
of  loss should the  price of the  security or currency  decline. Unlike one who
owns securities or currencies not subject to an option, the Fund has no  control
over  when it may be  required to sell the  underlying securities or currencies,
since most  options  may  be  exercised  at  any  time  prior  to  the  option's
expiration.  If a call option  that the Fund has  written expires, the Fund will
realize a gain in the amount of the premium; however, such gain may be offset by
a decline in the market value of the underlying security or currency during  the
option  period. If the call option is exercised, the Fund will realize a gain or
loss from  the  sale of  the  underlying security  or  currency, which  will  be
increased  or  offset by  the premium  received.  The Fund  does not  consider a
security or currency covered by  a call option to be  "pledged" as that term  is
used in the Fund's policy that limits the pledging or mortgaging of its assets.
 
Writing  call options can serve as a limited short hedge because declines in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
appreciates to a price higher than the exercise price of the call option, it can
be expected that the option will be exercised and the Fund will be obligated  to
sell the security or currency at less than its market value.
 
The  premium  that the  Fund receives  for writing  a call  option is  deemed to
constitute the market value of an option. The premium the Fund will receive from
writing a call option will reflect, among other things, the current market price
of the underlying  investment, the relationship  of the exercise  price to  such
market  price, the historical price volatility of the underlying investment, and
the length of the option period. In determining whether a particular call option
should  be  written,  the  Manager  will  consider  the  reasonableness  of  the
anticipated premium and the likelihood that a liquid secondary market will exist
for those options.
 
Closing  transactions  will be  effected  in order  to  realize a  profit  on an
outstanding call  option, to  prevent an  underlying security  or currency  from
being  called, or  to permit  the sale of  the underlying  security or currency.
Furthermore, effecting  a closing  transaction  will permit  the Fund  to  write
another  call  option  on the  underlying  security  or currency  with  either a
different exercise price, expiration date or both.
 
The Fund will pay  transaction costs in connection  with the writing of  options
and  in entering into closing purchase  contracts. Transaction costs relating to
options activity  normally are  higher than  those applicable  to purchases  and
sales of portfolio securities.
 
The  exercise price of the  options may be below, equal  to or above the current
market values of the underlying securities or currencies at the time the options
are written. From time to time, the Fund may purchase an underlying security  or
currency  for delivery in accordance with the exercise of an option, rather than
delivering such  security  or  currency  from  its  portfolio.  In  such  cases,
additional costs will be incurred.
 
The  Fund will realize a  profit or loss from  a closing purchase transaction if
the cost of  the transaction  is less or  more, respectively,  than the  premium
received  from writing the  option. Because increases  in the market  price of a
call option  generally  will  reflect  increases in  the  market  price  of  the
underlying  security or  currency, any loss  resulting from the  repurchase of a
call option is likely to  be offset in whole or  in part by appreciation of  the
underlying security or currency owned by the Fund.
 
WRITING PUT OPTIONS
The  Fund may  write put  options on securities,  indices and  currencies. A put
option gives the  purchaser of  the option  the right  to sell,  and the  writer
(seller)  the  obligation to  buy, the  underlying security  or currency  at the
exercise price at  any time until  (American style) or  on (European style)  the
expiration date. The operation of put options in other respects, including their
related risks and rewards, is substantially identical to that of call options.
 
The  Fund generally would  write put options in  circumstances where the Manager
wishes to purchase the underlying security or currency for the Fund's  portfolio
at  a price lower than the current market  price of the security or currency. In
such event, the Fund would write a put option at an exercise price that, reduced
by the premium received on the option, reflects the lower price it is willing to
pay. Since the Fund also would receive interest on debt securities or currencies
maintained to cover the  exercise price of the  option, this technique could  be
used to enhance current return during periods of market uncertainty. The risk in
such  a transaction would be that the market price of the underlying security or
currency would decline below the exercise price less the premium received.
 
Writing put options can serve as a  limited long hedge because increases in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
depreciates  to a price lower than the exercise  price of the put option, it can
be expected that the put option will be exercised and the Fund will be obligated
to purchase the security or currency at greater than its market value.

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

                         GT GLOBAL GROWTH & INCOME FUND
 
Options  may  be either  listed  on an  exchange  or traded  in over-the-counter
("OTC") markets. Listed options are third-party contracts (I.E., performance  of
the  obligations of the  purchaser and seller  is guaranteed by  the exchange or
clearing corporation), and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates. The Fund will not  purchase an OTC option  unless it believes that  daily
valuations  for such  options are  readily obtainable.  OTC options  differ from
exchange-traded options in that OTC options are transacted with dealers directly
and  not  through  a   clearing  corporation  (which  guarantees   performance).
Consequently,  there  is  a risk  of  non-performance  by the  dealer.  Since no
exchange is involved, OTC options are valued  on the basis of an average of  the
last  bid prices obtained from dealers, unless  a quotation from only one dealer
is available, in which case only that  dealer's price will be used. In the  case
of  OTC options, there can  be no assurance that  a liquid secondary market will
exist for any particular option at any specific time.
 
The staff of the Securities and Exchange Commission ("SEC") considers  purchased
OTC  options to be illiquid securities. The  Fund may also sell OTC options and,
in connection therewith, segregate assets or cover its obligations with  respect
to  OTC options written  by the Fund. The  assets used as  cover for OTC options
written by the Fund will be considered illiquid unless the OTC options are  sold
to  qualified dealers who agree  that the Fund may  repurchase any OTC option it
writes at a maximum price to be calculated by a formula set forth in the  option
agreement.  The cover for an OTC option  written subject to this procedure would
be considered illiquid  only to  the extent  that the  maximum repurchase  price
under the formula exceeds the intrinsic value of the option.
 
The  Fund's  ability to  establish and  close  out positions  in exchange-listed
options depends  on  the existence  of  a liquid  market.  The Fund  intends  to
purchase  or write only those exchange-traded options for which there appears to
be a liquid secondary  market. However, there  can be no  assurance that such  a
market  will exist at any particular time.  Closing transactions can be made for
OTC options  only  by  negotiating  directly  with the  contra  party  or  by  a
transaction in the secondary market if any such market exists. Although the Fund
will  enter into OTC  options only with  contra parties that  are expected to be
capable of  entering  into closing  transactions  with  the Fund,  there  is  no
assurance that the Fund will in fact be able to close out an OTC option position
at  a favorable  price prior to  expiration. In  the event of  insolvency of the
contra party, the Fund might  be unable to close out  an OTC option position  at
any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts  except that all settlements  are in cash and  gain or loss depends on
changes in the index in question (and thus on price movements in the  securities
market  or a particular market sector  generally) rather than on price movements
in individual securities or futures contracts. When the Fund writes a call on an
index, it receives a premium and agrees that, prior to the expiration date,  the
purchaser  of the call, upon exercise of the call, will receive from the Fund an
amount of cash if the closing level of the index upon which the call is based is
greater than the exercise price of the call. The amount of cash is equal to  the
difference  between the closing price of the index and the exercise price of the
call times a specified multiple  (the "multiplier"), which determines the  total
dollar  value for each point of such difference. When the Fund buys a call on an
index, it  pays a  premium  and has  the same  rights  as to  such call  as  are
indicated above. When the Fund buys a put on an index, it pays a premium and has
the  right, prior to the expiration date, to require the seller of the put, upon
the Fund's exercise of the put, to deliver to the Fund an amount of cash if  the
closing level of the index upon which the put is based is less than the exercise
price  of the  put, which  amount of  cash is  determined by  the multiplier, as
described above for calls. When the Fund writes a put on an index, it receives a
premium and  the purchaser  has the  right,  prior to  the expiration  date,  to
require  the Fund  to deliver to  it an amount  of cash equal  to the difference
between the  closing  level  of the  index  and  the exercise  price  times  the
multiplier, if the closing level is less than the exercise price.
 
The  risks  of  investment in  index  options  may be  greater  than  options on
securities. Because index options are settled in cash, when a Fund writes a call
on  an  index  it  cannot  provide  in  advance  for  its  potential  settlement
obligations  by acquiring  and holding the  underlying securities.  The Fund can
offset some of the  risk of writing  a call index option  position by holding  a
diversified  portfolio of  securities similar to  those on  which the underlying
index is based.  However, the Fund  cannot, as a  practical matter, acquire  and
hold  a portfolio containing  exactly the same securities  as underlie the index
and, as a result, bears a risk that  the value of the securities held will  vary
from the value of the index.
 
Even  if the Fund could assemble  a securities portfolio that exactly reproduced
the composition of  the underlying index,  it still would  not be fully  covered
from  a risk standpoint because  of the "timing risk"  inherent in writing index
options. When an index option is exercised,  the amount of cash that the  holder
is  entitled to  receive is  determined by  the difference  between the exercise
price and the closing index level on  the date when the option is exercised.  As
with  other kinds of options, the Fund as  the call writer will not know that it
has been assigned  until the next  business day  at the earliest.  The time  lag
between  exercise and  notice of assignment  poses no  risk for the  writer of a
covered call on a specific underlying
 
                   Statement of Additional Information Page 8

                         GT GLOBAL GROWTH & INCOME FUND
security, such as  common stock,  because there  the writer's  obligation is  to
deliver  the underlying security, not to pay its value as of a fixed time in the
past. So long as the writer already owns the underlying security, it can satisfy
its settlement obligations by simply delivering it, and the risk that its  value
may  have declined since the exercise date is borne by the exercising holder. In
contrast, even if  the writer  of an index  call holds  securities that  exactly
match  the composition of the  underlying index, it will  not be able to satisfy
its assignment obligations by delivering those securities against payment of the
exercise price. Instead, it will be required  to pay cash in an amount based  on
the  closing index value on the exercise date; and by the time it learns that it
has been assigned, the index may have declined, with a corresponding decline  in
the  value  of  its securities  portfolio.  This  "timing risk"  is  an inherent
limitation on the ability of index call writers to cover their risk exposure  by
holding securities positions.
 
If  the Fund purchases an index option and exercises it before the closing index
value for  that day  is  available, it  runs  the risk  that  the level  of  the
underlying  index may subsequently change. If such a change causes the exercised
option to fall out-of-the-money, the Fund will be required to pay the difference
between the closing index value and the exercise price of the option (times  the
applicable multiplier) to the assigned writer.
 
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
   
The  Fund may enter  into interest rate  or currency futures  contracts, and may
enter into stock  index futures contracts  (collectively, "Futures" or  "Futures
Contracts"),  as a hedge against changes in prevailing levels of interest rates,
currency exchange rates or  stock prices in order  to establish more  definitely
the effective return on securities or currencies held or intended to be acquired
by  the  Fund. The  Fund's hedging  may include  sales of  Futures as  an offset
against the effect  of expected  increases in  interest rates  and decreases  in
currency  exchange rates or stock prices, and  purchases of Futures as an offset
against the effect  of expected  declines in  interest rates,  and increases  in
currency exchange rates or stock prices.
    
 
The  Fund only  will enter  into Futures  Contracts that  are traded  on futures
exchanges and  are standardized  as to  maturity date  and underlying  financial
instrument.  Futures  exchanges and  trading thereon  in  the United  States are
regulated under  the Commodity  Exchange Act  by the  Commodity Futures  Trading
Commission ("CFTC"). Futures are exchanged in London at the London International
Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used  to reduce the Fund's exposure to interest rate, currency exchange rate and
stock market  fluctuations, the  Fund may  be able  to hedge  its exposure  more
effectively and at a lower cost through using Futures Contracts.
 
A  Futures Contract provides  for the future  sale by one  party and purchase by
another party of a specified amount of a specific financial instrument (security
or currency) for a specified price at a designated date, time and place. A stock
index Futures Contract provides for the delivery, at a designated date, time and
place, of  an amount  of  cash equal  to a  specified  dollar amount  times  the
difference between the stock index value at the close of trading on the contract
and  the price at which  the Futures Contract is  originally struck; no physical
delivery of stocks  comprising the index  is made. Brokerage  fees are  incurred
when  a  Futures  Contract  is  bought or  sold,  and  margin  deposits  must be
maintained at all times the Futures Contract is outstanding.
 
Although Futures Contracts typically require future delivery of and payment  for
financial  instruments or currencies,  Futures Contracts usually  are closed out
before the delivery date. Closing out an open Futures Contract sale or  purchase
is  effected by entering  into an offsetting Futures  Contract purchase or sale,
respectively,  for  the  same  aggregate  amount  of  the  identical   financial
instrument  or currency and  the same delivery date.  If the offsetting purchase
price is less than the original sale price,  the Fund realizes a gain; if it  is
more, the Fund realizes a loss. Conversely, if the offsetting sale price is more
than  the original purchase price, the Fund realizes  a gain; if it is less, the
Fund realizes  a loss.  The transaction  costs also  must be  included in  these
calculations.  There can be no assurance, however, that the Fund will be able to
enter into  an  offsetting transaction  with  respect to  a  particular  Futures
Contract  at  a particular  time.  If the  Fund  is not  able  to enter  into an
offsetting transaction, the Fund  will continue to be  required to maintain  the
margin deposits on the Futures Contract.
 
As  an example of an offsetting transaction, the contractual obligations arising
from the sale of one Futures Contract of September Deutschemarks on an  exchange
may  be fulfilled  at any  time before  delivery under  the Futures  Contract is
required (I.E., on a specified date  in September, the "delivery month") by  the
purchase  of another  Futures Contract  of September  Deutschemarks on  the same
exchange. In such instance the difference between the price at which the Futures
Contract was  sold  and  the  price paid  for  the  offsetting  purchase,  after
allowance for transaction costs, represents the profit or loss to the Fund.
 
The  Fund's Futures transactions will be entered into for hedging purposes only;
that is, Futures  Contracts will be  sold to  protect against a  decline in  the
price  of securities or currencies that the Fund owns, or Futures Contracts will
be purchased

to protect the Fund against an increase in the price of securities or currencies
it has committed to purchase or expects to purchase.
 
"Margin" with respect to Futures Contracts is  the amount of funds that must  be
deposited  by the Fund in order to  initiate Futures trading and to maintain the
Fund's open  positions in  Futures Contracts.  A margin  deposit made  when  the
Futures  Contract is entered  into ("initial margin") is  intended to assure the
Fund's performance  under  the  Futures  Contract. The  margin  required  for  a
particular Futures Contract is set by the exchange on which the Futures Contract
is  traded, and may be modified significantly  from time to time by the exchange
during the term of the Futures Contract.
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission  merchant through  which the Fund  entered into  the Futures Contract
will be made on a daily basis as the price of the underlying security,  currency
or index fluctuates making the Futures Contract more or less valuable, a process
known as marking-to-market.
 
    RISKS  OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts are
volatile and  are influenced,  among  other things,  by actual  and  anticipated
changes  in  interest rates  and currency  exchange rates,  and in  stock market
movements, which  in turn  are  affected by  fiscal  and monetary  policies  and
national and international political and economic events.
 
   
There  is a risk of  imperfect correlation between changes  in prices of Futures
Contracts and prices  of the securities  or currencies in  the Fund's  portfolio
being   hedged.  The  degree   of  imperfection  of   correlation  depends  upon
circumstances such as: variations in  speculative market demand for Futures  and
for securities or currencies, including technical influences in Futures trading;
and   differences  between  the  financial  instruments  being  hedged  and  the
instruments underlying the standard Futures  Contracts available for trading.  A
decision  of whether, when,  and how to  hedge involves skill  and judgment, and
even a  well-conceived hedge  may  be unsuccessful  to  some degree  because  of
unexpected market behavior or interest or currency rate trends.
    
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and options on Futures Contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a Futures  Contract
or option may vary either up or down from the previous day's settlement price at
the  end  of a  trading session.  Once the  daily  limit has  been reached  in a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a particular trading day and therefore does not limit potential losses,  because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and  option  prices  occasionally have  moved  to  the daily  limit  for several
consecutive trading days with  little or no  trading, thereby preventing  prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If the Fund were unable to liquidate a Futures or option on Futures position due
to  the absence of a liquid secondary  market or the imposition of price limits,
it could incur  substantial losses.  The Fund would  continue to  be subject  to
market  risk with respect  to the position.  In addition, except  in the case of
purchased options,  the  Fund  would  continue to  be  required  to  make  daily
variation  margin payments and might be  required to maintain the position being
hedged by the Future or option or to maintain cash or securities in a segregated
account.
 
Certain characteristics  of the  Futures  market might  increase the  risk  that
movements  in the prices  of Futures Contracts  or options on  Futures might not
correlate perfectly  with  movements in  the  prices of  the  investments  being
hedged.  For example,  all participants  in the  Futures and  options on Futures
markets are subject to  daily variation margin calls  and might be compelled  to
liquidate  Futures  or  options on  Futures  positions whose  prices  are moving
unfavorably to avoid being  subject to further  calls. These liquidations  could
increase  price  volatility  of the  instruments  and distort  the  normal price
relationship between the Futures  or options and  the investments being  hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous  than  margin requirements  in the  securities  markets, there  might be
increased  participation   by  speculators   in   the  Futures   markets.   This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading"  and other  investment strategies  might result  in
temporary price distortions.

OPTIONS ON FUTURES CONTRACTS
Options  on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the  premium paid,  to  assume a  position in  a  Futures Contract  (a  long
position if the option is a call and a short position if the option is a put) at
a  specified exercise price  at any time  during the period  of the option. Upon
exercise of the option, the  delivery of the Futures  position by the writer  of
the  option to the holder  of the option will be  accompanied by delivery of the
accumulated balance in the writer's Futures margin account, which represents the
amount by which the market price  of the Futures Contract, at exercise,  exceeds
(in  the case of  a call) or  is less than (in  the case of  a put) the exercise
price of the option on  the Futures Contract. If an  option is exercised on  the
last trading day prior to the expiration date of the option, the settlement will
be  made entirely in cash equal to  the difference between the exercise price of
the option and  the closing level  of the securities,  currencies or index  upon
which  the  Futures Contract  is  based on  the  expiration date.  Purchasers of
options who fail to exercise their options  prior to the exercise date suffer  a
loss of the premium paid.
 
The  purchase of  call options  on Futures can  serve as  a long  hedge, and the
purchase of put  options on Futures  can serve  as a short  hedge. Writing  call
options  on Futures can serve as a  limited short hedge, and writing put options
on Futures can serve as a limited  long hedge, using a strategy similar to  that
used for writing options on securities, foreign currencies or indices.
 
If  the Fund  writes an  option on a  Futures Contract,  it will  be required to
deposit initial and variation margin  pursuant to requirements similar to  those
applicable to Futures Contracts. Premiums received from the writing of an option
on a Futures Contract are included in the initial margin deposit.
 
The  Fund may seek to close out an option position by selling an option covering
the same Futures  Contract and  having the  same exercise  price and  expiration
date.  The  ability to  establish and  close  out positions  on such  options is
subject to the maintenance of a liquid secondary market.
 
LIMITATIONS ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS  ON
CURRENCIES
To  the extent that the  Fund enters into Futures  Contracts, options on Futures
Contracts,  and  options  on  foreign  currencies  traded  on  a  CFTC-regulated
exchange,  in each case other than for BONA FIDE hedging purposes (as defined by
the CFTC), the aggregate initial margin and premiums required to establish those
positions (excluding the amount  by which options  are "in-the-money") will  not
exceed  5% of the liquidation  value of the Fund's  portfolio, after taking into
account unrealized profits and unrealized losses  on any contracts the Fund  has
entered   into.  In   general,  a   call  option   on  a   Futures  Contract  is
"in-the-money"if the  value  of  the underlying  Futures  Contract  exceeds  the
strike, I.E., exercise, price of the call; a put option on a Futures Contract is
"in-the-money"  if the value  of the underlying Futures  Contract is exceeded by
the strike price of  the put. This  guideline may be  modified by the  Company's
Board  of Directors without  a shareholder vote. This  limitation does not limit
the percentage of the Fund's assets at risk to 5%.
 
FORWARD CONTRACTS
A Forward Contract is an obligation, usually arranged with a commercial bank  or
other  currency dealer, to purchase or  sell a currency against another currency
at a future date and  price as agreed upon by  the parties. The Fund either  may
accept or make delivery of the currency at the maturity of the Forward Contract.
The  Fund may also, if its contra party  agrees, prior to maturity, enter into a
closing transaction involving the purchase or sale of an offsetting contract.
 
The Fund engages  in forward  currency transactions  in anticipation  of, or  to
protect  itself against, fluctuations  in exchange rates. The  Fund might sell a
particular  foreign  currency  forward,  for   example,  when  it  holds   bonds
denominated  in a  foreign currency but  anticipates, and seeks  to be protected
against, a decline in the currency against the U.S. dollar. Similarly, the  Fund
might  sell the  U.S. dollar  forward when  it holds  bonds denominated  in U.S.
dollars but anticipates,  and seeks to  be protected against,  a decline in  the
U.S.  dollar relative  to other currencies.  Further, the Fund  might purchase a
currency forward  to "lock  in"  the price  of  securities denominated  in  that
currency that it anticipates purchasing.
 
Forward  Contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement and no commissions are charged  at
any stage for trades. The Fund will enter into such Forward Contracts with major
U.S.  or foreign banks and securities or currency dealers in accordance with the
guidelines approved by the Company's Board of Directors.
 
The Fund  may enter  into  Forward Contracts  either  with respect  to  specific
transactions  or with  respect to  the Fund's  portfolio positions.  The precise
matching of the Forward  Contract amounts and the  value of specific  securities
generally  will not be possible  because the future value  of such securities in
foreign currencies will change as a consequence of market movements in the value
of those securities between  the date the Forward  Contract is entered into  and
the date it matures.
 
                  Statement of Additional Information Page 11
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
Accordingly,  it may  be necessary for  the Fund to  purchase additional foreign
currency on the spot (I.E., cash) market (and bear the expense of such purchase)
if the market value of the security is less than the amount of foreign  currency
the  Fund is obligated to deliver and if a decision is made to sell the security
and make delivery of  the foreign currency. Conversely,  it may be necessary  to
sell  on the spot market  some of the foreign currency  the Fund is obligated to
deliver. The projection  of short-term  currency market  movements is  extremely
difficult,  and the  successful execution  of a  short-term hedging  strategy is
highly uncertain. Forward Contracts involve  the risk that anticipated  currency
movements  will not be predicted accurately,  causing the Fund to sustain losses
on these contracts and transaction costs.
 
   
At or before the  maturity of a  Forward Contract requiring the  Fund to sell  a
currency,  the  Fund either  may  sell a  portfolio  security and  use  the sale
proceeds to make delivery of the currency or retain the security and offset  its
contractual  obligation to deliver the currency  by purchasing a second contract
pursuant to which  the Fund will  obtain, on  the same maturity  date, the  same
amount  of the currency that it is obligated to deliver. Similarly, the Fund may
close out a Forward  Contract requiring it to  purchase a specified currency  by
entering  into a second  contract, if its  contra party agrees,  entitling it to
sell the same  amount of the  same currency on  the maturity date  of the  first
contract.  The Fund would  realize a gain or  loss as a  result of entering into
such an offsetting Forward Contract under either circumstance to the extent  the
exchange  rate  or  rates  between the  currencies  involved  moved  between the
execution dates of the first contract and the offsetting contract.
    
 
The cost to the Fund of engaging  in Forward Contracts varies with factors  such
as  the currencies involved,  the length of  the contract period  and the market
conditions then prevailing. Because Forward  Contracts usually are entered  into
on  a principal basis, no  fees or commissions are  involved. The use of Forward
Contracts does  not  eliminate fluctuations  in  the prices  of  the  underlying
securities  the Fund owns or intends to acquire, but it does establish a rate of
exchange in advance. In addition, while Forward Contract sales limit the risk of
loss due to a decline in the value of the hedged currencies, they also limit any
potential gain that might result should the value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
The Fund may use options on  foreign currencies, Futures on foreign  currencies,
options  on Futures on foreign currencies and Forward Contracts to hedge against
movements in the values of the foreign currencies in which the Fund's securities
are denominated. Such currency hedges can  protect against price movements in  a
security  that the  Fund owns  or intends  to acquire  that are  attributable to
changes in the value of the currency in which it is denominated. Such hedges  do
not,  however,  protect  against  price movements  in  the  securities  that are
attributable to other causes.
 
The Fund  might seek  to hedge  against changes  in the  value of  a  particular
currency  when no  Futures Contract, Forward  Contract or  option involving that
currency is available or  one of such contracts  is more expensive than  certain
other  contracts. In such cases,  the Fund may hedge  against price movements in
that currency  by entering  into a  contract on  another currency  or basket  of
currencies,  the  values of  which  the Manager  believes  will have  a positive
correlation to the value of the  currency being hedged. The risk that  movements
in  the price of the contract will not correlate perfectly with movements in the
price of the currency being hedged is magnified when this strategy is used.
 
The value of Futures Contracts, options on Futures Contracts, Forward Contracts,
and options  on  foreign currencies  depends  on  the value  of  the  underlying
currency  relative  to the  U.S. dollar.  Because foreign  currency transactions
occurring in the  interbank market  might involve  substantially larger  amounts
than  those  involved in  the  use of  Futures  Contracts, Forward  Contracts or
options, the  Fund could  be disadvantaged  by  dealing in  the odd  lot  market
(generally  consisting  of  transactions  of  less  than  $1  million)  for  the
underlying foreign currencies at prices that  are less favorable than for  round
lots.
 
There is no systematic reporting of last sale information for foreign currencies
or  any  regulatory requirements  that quotations  available through  dealers or
other market sources be firm or revised on a timely basis. Quotation information
generally is representative of very  large transactions in the interbank  market
and  thus  might not  reflect  odd-lot transactions  where  rates might  be less
favorable.  The   interbank  market   in  foreign   currencies  is   a   global,
round-the-clock  market. To the  extent the U.S. options  or Futures markets are
closed while the markets for the underlying currencies remain open,  significant
price  and rate movements might take place in the underlying markets that cannot
be reflected in  the markets  for the Futures  contracts or  options until  they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies  might  be required  to  take place  within  the country  issuing the
underlying currency. Thus, the Fund might be required to accept or make delivery
of the  underlying foreign  currency  in accordance  with  any U.S.  or  foreign
regulations  regarding the maintenance  of foreign banking  arrangements by U.S.
residents and might be  required to pay any  fees, taxes and charges  associated
with such delivery assessed in the issuing country.

COVER
Transactions  using Forward Contracts, Futures Contracts and options (other than
options purchased  by the  Fund) expose  the Fund  to an  obligation to  another
party.  The Fund will not enter into any such transactions unless it owns either
(1) an  offsetting  ("covered") position  in  securities, currencies,  or  other
options,  Forward Contracts or  Futures Contracts, or  (2) cash, receivables and
short-term debt securities  with a value  sufficient at all  times to cover  its
potential obligations not covered as provided in (1) above. The Fund will comply
with SEC guidelines regarding cover for these instruments and, if the guidelines
so require, set aside cash or liquid securities.
 
Assets  used as cover or  held in a segregated account  cannot be sold while the
position in the corresponding  Forward Contract, Futures  Contract or option  is
open, unless they are replaced with other appropriate assets. If a large portion
of  the Fund's assets are used for cover or otherwise set aside, it could affect
portfolio management or the Fund's ability to meet redemption requests or  other
current obligations.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
   
The  Fund  may  invest up  to  10% of  its  net assets  in  illiquid securities.
Securities may  be considered  illiquid  if the  Fund cannot  reasonably  expect
within  seven days to sell the securities  for approximately the amount at which
the Fund values such securities. The sale of illiquid securities, if they can be
sold at all,  generally will require  more time and  result in higher  brokerage
charges  or dealer discounts and other selling  expenses than the sale of liquid
securities, such as securities eligible for trading on U.S. securities exchanges
or in the over-the-counter markets. Moreover, restricted securities which may be
illiquid for purposes  of this limitation,  often sell,  if at all,  at a  price
lower than similar securities that are not subject to restrictions on resale.
    
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, the Fund  may be obligated to pay  all or part of the
registration expenses and a considerable period  may elapse between the time  of
the  decision to sell and the time the  Fund may be permitted to sell a security
under an effective  registration statement.  If, during such  a period,  adverse
market  conditions were to develop, the Fund might obtain a less favorable price
than prevailed when it decided to sell.
 
Not  all  restricted  securities   are  illiquid.  In   recent  years  a   large
institutional   market  has  developed  for  certain  securities  that  are  not
registered under the Securities Act of 1933, as amended ("1933 Act"),  including
private  placements, repurchase agreements, commercial paper, foreign securities
and corporate bonds and notes. These instruments are often restricted securities
because the  securities are  sold in  transactions not  requiring  registration.
Institutional investors generally will not seek to sell these instruments to the
general   public,  but  instead  will  often   depend  either  on  an  efficient
institutional market in which such unregistered securities can be readily resold
or on an issuer's ability to honor  a demand for repayment. Therefore, the  fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule  144A under the 1933 Act establishes  a "safe harbor" from the registration
requirements of the  1933 Act  for resales  of certain  securities to  qualified
institutional  buyers.  Institutional  markets  for  restricted  securities have
developed as a result of Rule 144A, providing both readily ascertainable  values
for  restricted securities and the ability to liquidate an investment to satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance and  settlement of  unregistered securities  of domestic  and  foreign
issuers,  such as  the PORTAL  System sponsored  by the  National Association of
Securities Dealers,  Inc.  An  insufficient number  of  qualified  institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a  Fund, however,  could affect  adversely the  marketability of  such portfolio
securities and the Fund might be  unable to dispose of such securities  promptly
or at favorable prices.
 
With  respect  to liquidity  determinations  generally, the  Company's  Board of
Directors 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 Manager
 
                  Statement of Additional Information Page 13
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
in accordance with procedures approved by the Company's Board of Directors.  The
Manager  takes into account a number of factors in reaching liquidity decisions,
including, but not  limited to: (i)  the frequency of  trading in the  security;
(ii) the number of dealers who make quotes for the security; (iii) the number of
dealers who have undertaken to make a market in the security; (iv) the number of
other  potential purchasers; and (v) the nature  of the security and how trading
is effected  (e.g.,  the  time needed  to  sell  the security,  how  offers  are
solicited  and the mechanics of transfer). The Manager monitors the liquidity of
securities in the Fund's portfolio and periodically reports on such decisions to
the Board of Directors.
 
FOREIGN SECURITIES
    POLITICAL, SOCIAL AND  ECONOMIC RISKS. Investing  in securities of  non-U.S.
companies may entail additional risks due to the potential political, social and
economic  instability  of  certain  countries and  the  risks  of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment,  convertibility of currencies into  U.S. dollars and on repatriation
of capital  invested. In  the event  of such  expropriation, nationalization  or
other  confiscation by any country, the Fund could lose its entire investment in
any such country.
 
   
    RELIGIOUS AND ETHNIC INSTABILITY.  Certain countries in  which the Fund  may
invest  may  have  groups  that  advocate  radical  religious  or  revolutionary
philosophies or support ethnic independence. Any disturbance on the part of such
individuals could carry the potential for widespread destruction or confiscation
of property owned by individuals and entities foreign to such country and  could
cause the loss of the Fund's investment in those countries. Instability may also
result  from,  among other  things:  (i) authoritarian  governments  or military
involvement in  political and  economic  decision-making, including  changes  in
government  through extra-constitutional  means; (ii)  popular unrest associated
with demands for improved political,  economic and social conditions; and  (iii)
hostile  relations with neighboring  or other countries.  Such political, social
and economic instability could disrupt the principal financial markets in  which
the Fund invests and adversely affect the value of the Fund's assets.
    
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial restrictions on investments  in their capital markets,  particularly
their  equity markets, by foreign entities  such as the Fund. These restrictions
or controls may at times limit or preclude investment in certain securities  and
may  increase the cost and expenses of  the Fund. For example, certain countries
require prior governmental approval before investments by foreign persons may be
made, or may limit the amount of  investment by foreign persons in a  particular
company,  or limit the investment by foreign persons to only a specific class of
securities of a company that may have less advantageous terms than securities of
the company available for purchase by nationals. Moreover, the national policies
of certain  countries  may  restrict  investment  opportunities  in  issuers  or
industries  deemed sensitive to national  interests. In addition, some countries
require governmental approval for the repatriation of investment income, capital
or the proceeds of securities sales by foreign investors. In addition, if  there
is  a deterioration in a  country's balance of payments  or for other reasons, a
country may impose restrictions on foreign capital remittances abroad. The  Fund
could  be adversely affected by  delays in, or a  refusal to grant, any required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that  differ in some  cases significantly from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting principles. Most of the foreign securities held by the  Fund
will  not be registered with  the SEC or regulators  of any foreign country, nor
will the issuers thereof be subject  to the SEC's reporting requirements.  Thus,
there  will be  less available  information concerning  most foreign  issuers of
securities held  by the  Fund  than is  available  concerning U.S.  issuers.  In
instances  where the financial statements of an issuer are not deemed to reflect
accurately the  financial  situation  of  the  issuer,  the  Manager  will  take
appropriate steps to evaluate the proposed investment, which may include on-site
inspection  of the issuer, interviews with its management and consultations with
accountants, bankers and other specialists. There is substantially less publicly
available information about foreign companies than there are reports and ratings
published about  U.S. companies  and  the U.S.  Government. In  addition,  where
public  information is available, it may  be less reliable than such information
regarding U.S.  issuers.  Issuers of  securities  on foreign  jurisdictions  are
generally  not subject to the same degree of regulation as are U.S. issuers with
respect to such matters as restrictions on market manipulation, insider  trading
rules, shareholder proxy requirements and timely disclosure of information.
 
    CURRENCY  FLUCTUATIONS. Because  the Fund, under  normal circumstances, will
invest a substantial portion  of its total assets  in the securities of  foreign
issuers which are denominated in foreign currencies, the strength or weakness of
the  U.S. dollar against  such foreign currencies  will account for  part of the
Fund's investment performance. A decline in the value of any particular currency
against the U.S. dollar  will cause a  decline in the U.S.  dollar value of  the
Fund's holdings of
 
                  Statement of Additional Information Page 14
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
securities  and cash denominated in such  currency and, therefore, will cause an
overall decline in the Fund's net asset value and any net investment income  and
capital  gains derived from such securities to be distributed in U.S. dollars to
shareholders of the Fund.  Moreover, if the value  of the foreign currencies  in
which  the Fund receives  its income falls  relative to the  U.S. dollar between
receipt of the  income and the  making of  Fund distributions, the  Fund may  be
required  to liquidate securities in order to make distributions if the Fund has
insufficient cash in U.S. dollars to meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors including  the supply and  demand for particular currencies,
central bank efforts to support particular currencies, the movement of  interest
rates,  the pace of business  activity in certain other  countries and the U.S.,
and other economic and financial conditions affecting the world economy.
 
Although the Fund values  its assets daily  in terms of  U.S. dollars, the  Fund
does  not intend to convert its holdings of foreign currencies into U.S. dollars
on a daily basis. The Fund will do so from time to time, and investors should be
aware of the costs of currency conversion. Although foreign exchange dealers  do
not  charge  a  fee  for conversion,  they  do  realize a  profit  based  on the
difference ("spread") between the  prices at which they  are buying and  selling
various  currencies. Thus, a dealer may offer  to sell a foreign currency to the
Fund at one  rate, while  offering a  lesser rate  of exchange  should the  Fund
desire to sell that currency to the dealer.
 
    ADVERSE  MARKET CHARACTERISTICS. Securities  of many foreign  issuers may be
less liquid and their  prices more volatile than  securities of comparable  U.S.
issuers.  In  addition, foreign  securities  markets and  brokers  generally are
subject to less governmental  supervision and regulation than  in the U.S.,  and
foreign  securities transactions usually are subject to fixed commissions, which
generally are  higher  than  negotiated commissions  on  U.S.  transactions.  In
addition,  foreign  securities  transactions  may  be  subject  to  difficulties
associated with the settlement of such transactions. Delays in settlement  could
result in temporary periods when assets of the Fund are uninvested and no return
is earned thereon. The inability of the Fund to make intended security purchases
due   to  settlement   problems  could  cause   the  Fund   to  miss  attractive
opportunities. Inability to dispose  of a portfolio  security due to  settlement
problems either could result in losses to the Fund due to subsequent declines in
value  of the portfolio security or, if the  Fund has entered into a contract to
sell the security,  could result  in possible  liability to  the purchaser.  The
Manager  will consider such difficulties when  determining the allocation of the
Fund's assets, although the Manager does not believe that such difficulties will
have a material adverse effect on the Fund's portfolio trading activities.
 
The Fund may  use foreign  custodians, which may  involve risks  in addition  to
those  related to the  use of U.S. custodians.  Such risks include uncertainties
relating to: (i) determining and  monitoring the financial strength,  reputation
and  standing of the foreign  custodian; (ii) maintaining appropriate safeguards
to protect the Fund's investments  and (iii) possible difficulties in  obtaining
and enforcing judgments against such custodians.
 
    WITHHOLDING TAXES. The Fund's net investment income from foreign issuers may
be  subject  to  withholding  taxes by  the  foreign  issuer's  country, thereby
reducing the Fund's  net investment  income or  delaying the  receipt of  income
where those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION.  To the extent the Fund  invests a significant portion of its
assets in securities of issuers located in a particular country or region of the
world, it may be subject to greater risks and may experience greater  volatility
than a fund that is more broadly diversified geographically.
 
    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Belgium,
Denmark,  France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg, Netherlands,
Portugal, Spain, and the United  Kingdom) eliminated certain import tariffs  and
quotas  and  other trade  barriers with  respect  to one  another over  the past
several years. The Manager  believes that this  deregulation should improve  the
prospects  for economic growth  in many Western  European countries. Among other
things, the  deregulation could  enable companies  domiciled in  one country  to
avail  themselves of lower labor costs existing in other countries. In addition,
this deregulation could benefit  companies domiciled in  one country by  opening
additional  markets  for their  goods and  services  in other  countries. Since,
however, it is not clear  what the exact form or  effect of these Common  Market
reforms  will be on business in Western  Europe, it is impossible to predict the
long-term impact of the implementation of these programs on the securities owned
by the Fund.
 
    SPECIAL CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN  COUNTRIES.
Investing  in Russia  and Eastern European  countries involves a  high degree of
risk and special considerations not  typically associated with investing in  the
United  States securities markets, and  should be considered highly speculative.
Such risks include: (1)  delays in settling portfolio  transactions and risk  of
loss  arising out of the system of  share registration and custody; (2) the risk
that it may be
 
                  Statement of Additional Information Page 15

                         GT GLOBAL GROWTH & INCOME FUND
impossible or more difficult than in other countries to obtain and/or enforce  a
judgement; (3) pervasiveness of corruption and crime in the economic system; (4)
currency  exchange rate  volatility and the  lack of  available currency hedging
instruments; (5) higher rates of inflation (including the risk of social  unrest
associated  with periods of hyper-inflation) and high unemployment; (6) controls
on foreign  investment and  local practices  disfavoring foreign  investors  and
limitations on repatriation of invested capital, profits and dividends, and on a
fund's  ability to  exchange local  currencies for  U.S. dollars;  (7) political
instability and social unrest and violence; (8) the risk that the governments of
Russia and Eastern European countries may decide not to continue to support  the
economic  reform  programs  implemented  recently  and  could  follow  radically
different political  and/or economic  policies to  the detriment  of  investors,
including non-market-oriented policies such as the support of certain industries
at  the expense  of other  sectors or  investors, or  a return  to the centrally
planned economy  that  existed when  such  countries  had a  communist  form  of
government;  (9)  the  financial  condition  of  companies  in  these countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of international trade;  (11) the risk  that the tax  system in these  countries
will  not  be reformed  to prevent  inconsistent, retroactive  and/or exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly since 1990. The general government position has deteriorated as  a
result  of weakening economic  growth and stimulative  measures taken to support
economic activity and to  restore financial stability.  Although the decline  in
interest   rates  and  fiscal  stimulation   packages  have  helped  to  contain
recessionary forces, uncertainties remain. Japan is also heavily dependent  upon
international  trade, so its  economy is especially  sensitive to trade barriers
and disputes.  Japan has  had  difficult relations  with its  trading  partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible  that  trade sanctions  and other  protectionist measures  could impact
Japan adversely in both the short and the long term.
 
The common  stocks  of many  Japanese  companies trade  at  high  price-earnings
ratios.  Differences  in accounting  methods make  it  difficult to  compare the
earnings of  Japanese companies  with  those of  companies in  other  countries,
especially  in the  U.S. In  general, however, reported  net income  in Japan is
understated relative to  U.S. accounting standards  and this is  one reason  why
price-earnings   ratios  of  the  stocks   of  Japanese  companies  have  tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally  been lower than  in the  U.S., both  of
which  factors tend to result in  lower discount rates and higher price-earnings
ratios in Japan than in the U.S.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes  also exist  between  South Korea  and North  Korea.  In
addition,  the  Fund  may  invest  in  Hong  Kong,  which  reverted  to  Chinese
Administration on  July 1,  1997. Investments  in Hong  Kong may  be subject  to
expropriation, national, nationalization or confiscation, in which case the Fund
could  lose its entire  investment in Hong  Kong. In addition,  the reversion of
Hong Kong also presents a risk that the Hong Kong dollar will be devalued and  a
risk  of possible  loss of  investor confidence  in Hong  Kong's currency, stock
market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American  countries have experienced substantial,  and in some periods extremely
high, rates of  inflation for many  years. Inflation and  rapid fluctuations  in
inflation  rates have had and may continue  to have very negative effects on the
economies and securities  markets of certain  Latin American countries.  Certain
Latin  American countries are also among the largest debtors to commercial banks
and foreign governments. At times certain Latin American countries have declared
moratoria on  the payment  of principal  and/or interest  on external  debt.  In
addition,  certain  Latin  American  securities  markets  have  experienced high
volatility in recent years.
 
Latin American countries may  also close certain sectors  of their economies  to
equity  investments  by foreigners.  Further due  to  the absence  of securities
markets and  publicly  owned corporations  and  due to  restrictions  on  direct
investment  by foreign entities,  investments may only be  made in certain Latin
American  countries  solely   or  primarily   through  governmentally   approved
investment vehicles or companies.
 
                  Statement of Additional Information Page 16
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
Certain Latin American countries may have managed currencies that are maintained
at  artificial levels to the U.S. dollar rather than at levels determined by the
market. This type  of system can  lead to  sudden and large  adjustments in  the
currency  which, in turn, can  have a disruptive and  negative effect on foreign
investors. For example, in late  1994, the value of  the Mexican peso lost  more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL   CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in  the
securities of companies in emerging markets may entail special risks relating to
potential political and  economic instability  and the  risks of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment, convertibility  into U.S.  dollars and  on repatriation  of  capital
invested.   In  the  event  of  such  expropriation,  nationalization  or  other
confiscation by any country,  the Fund could lose  its entire investment in  any
such country.
 
Emerging  securities  markets are  substantially  smaller, less  developed, less
liquid and more volatile than the major securities markets. The limited size  of
emerging securities markets and limited trading value in issuers compared to the
volume  of  trading in  U.S. securities  could  cause prices  to be  erratic for
reasons apart  from factors  that  affect the  quality  of the  securities.  For
example, limited market size may cause prices to be unduly influenced by traders
who  control  large  positions. Adverse  publicity  and  investors' perceptions,
whether or  not  based on  fundamental  analysis,  may decrease  the  value  and
liquidity  of portfolio  securities, especially  in these  markets. In addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience of financial intermediaries, a lack of modern technology, the  lack
of  a sufficient capital base to expand business operations, and the possibility
of permanent or temporary termination of trading.
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in more developed markets.  In such emerging securities there may
be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economies  and securities
markets of certain emerging market countries.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
The Fund  has  adopted  the  following  investment  limitations  as  fundamental
policies  which (unless otherwise noted) may  not be changed without approval by
the holders 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 outstanding shares.
 
The Fund may not:
 
        (1) Invest  25%  or  more of  the  value  of its  total  assets  in  the
    securities  of issuers conducting their principal business activities in the
    same industry, except  that this  limitation shall not  apply to  securities
    issued  or guaranteed as to principal and interest by the U.S. Government or
    any of its agencies or instrumentalities;
 
        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;
 
        (3) Buy or sell real estate (including real estate limited partnerships)
    or  commodities or commodity contracts; however, the Fund may invest in debt
    securities secured  by  real  estate  or  interests  therein  or  issued  by
    companies  which invest in real estate  or interests therein, including real
    estate investment trusts,  and may  purchase or  sell currencies  (including
    forward  currency exchange contracts), futures contracts and related options
    generally as described in  the Prospectus and  this Statement of  Additional
    Information and subject to operating policy (4) below;
 
        (4)  Acquire  securities  subject  to  restrictions  on  disposition  or
    securities for which  there is no  readily available market,  or enter  into
    repurchase  agreements or purchase time deposits maturing in more than seven
    days, or purchase OTC options or hold assets set aside to cover OTC  options
    written  by the Fund,  if, immediately after  and as a  result, the value of
    such securities  would exceed,  in  the aggregate,  10%  of the  Fund's  net
    assets;
 
        (5)  Engage in the business of underwriting securities of other issuers,
    except to  the  extent that  the  disposal  of an  investment  position  may
    technically cause it to be considered an underwriter as that term is defined
    under the 1933 Act;
 
                  Statement of Additional Information Page 17

                         GT GLOBAL GROWTH & INCOME FUND
 
        (6)  Make loans, except  that the Fund may  purchase debt securities and
    enter into repurchase agreements and make loans of portfolio securities;
 
        (7) Purchase securities  on margin,  provided that the  Fund may  obtain
    such  short-term credits as may be  necessary for the clearance of purchases
    and sales  of  securities;  except  that it  may  make  margin  deposits  in
    connection with futures contracts subject to operating policy (4) below;
 
        (8)  Borrow money except from banks  for temporary or emergency purposes
    not in excess  of 33 1/3%  of the value  of the Fund's  total assets at  the
    lower  of cost or fair  market value. The Fund  will not purchase securities
    while borrowings in excess of 5%  of its total assets are outstanding.  This
    restriction shall not prevent the Fund from entering into reverse repurchase
    agreements  and  engaging  in  "roll"  transactions,  provided  that reverse
    repurchase  agreements,  "roll"  transactions  and  any  other  transactions
    constituting  borrowing by the  Fund may not exceed  one-third of the Fund's
    total assets. In the event that the asset coverage for the Fund's borrowings
    falls below 300%, the Fund will reduce, within three days (excluding Sundays
    and holidays), the  amount of its  borrowings in order  to provide for  300%
    asset coverage;
 
        (9)  Mortgage, pledge, or  hypothecate any of  its assets, provided that
    this restriction shall not apply to the transfer of securities in connection
    with any permissible borrowing or  to collateral arrangements in  connection
    with permissible activities;
 
       (10)  Invest in  interests in oil,  gas, or other  mineral exploration or
    development programs; or
 
       (11) Purchase or retain the securities of any issuer, if those individual
    officers and  Directors  of the  Company,  its investment  adviser,  or  its
    distributor,  each owning beneficially more than 1/2 of 1% of the securities
    of such issuer, together own more than 5% of the securities of such issuer.
 
For purposes  of the  Fund's concentration  policy contained  in limitation  (1)
above,  the Fund intends to  comply with the SEC  staff position that securities
issued or  guaranteed  as  to  principal and  interest  by  any  single  foreign
government or any supranational organizations in the aggregate are considered to
be securities of issuers in the same industry.
 
   
The  following operating policies  of the Fund are  not fundamental policies and
may be changed by vote of  the Company's Board of Directors without  shareholder
approval.  The  Fund may  not:  (1) invest  in securities  of  an issuer  if the
investment would cause the Fund to own more than 10% of any class of  securities
of any one issuer; (2) sell securities short, except to the extent that the Fund
contemporaneously  owns  or  has the  right  to  acquire at  no  additional cost
securities identical to those sold short; or (3) enter into a futures  contract,
an  option on a futures  contract, or an option on  foreign currency traded on a
CFTC-regulated exchange, in each case other than for BONA FIDE hedging  purposes
(as  defined by the CFTC), if the aggregate initial margin and premiums required
to establish all of those positions  (excluding the amount by which options  are
"in-the-money")  exceeds 5%  of the liquidation  value of  the Fund's portfolio,
after taking  into  account unrealized  profits  and unrealized  losses  on  any
contracts the Fund has entered into.
    
 
Investors should refer to the Prospectus for further information with respect to
the  Fund's investment objective, which may  not be changed without the approval
of the shareholders, and other investment policies, techniques and  limitations,
which may be changed without shareholder approval.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
   
Subject to policies established by the Company's Board of Directors, the Manager
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.
In executing portfolio transactions, the Manager seeks the best net results  for
the  Fund,  taking  into  account  such  factors  as  the  price  (including the
applicable brokerage commission or dealer spread), size of the order, difficulty
of execution  and operational  facilities  of the  firm involved.  Although  the
Manager  generally seeks  reasonably competitive  commission rates  and spreads,
payment of the lowest  commission or spread is  not necessarily consistent  with
the  best net results. While the Fund may engage in soft dollar arrangements for
research services, as described below, the  Fund has no obligation to deal  with
any  broker/dealer  or group  of broker/dealers  in  the execution  of portfolio
transactions.
    
 
Debt securities generally are traded  on a "net" basis  with a dealer acting  as
principal for its own account without a stated commission, although the price of
the  security  usually  includes  a  profit  to  the  dealer.  U.S.  and foreign
government securities and money market  instruments generally are traded in  the
OTC  markets. In underwritten  offerings, securities usually  are purchased at a
fixed price which  includes an  amount of  compensation to  the underwriter.  On
occasion,  securities may be purchased directly from an issuer, in which case no
commissions or discounts  are paid.  Broker/dealers may  receive commissions  on
futures, currency and options transactions.
 
   
Consistent  with the interests  of the Fund,  the Manager may  select brokers to
execute the Fund's  portfolio transactions,  on the  basis of  the research  and
brokerage  services they provide to the Manager for its use in managing the Fund
and its other advisory accounts. Such services may include furnishing  analyses,
reports  and information concerning  issuers, industries, securities, geographic
regions, economic factors  and trends,  portfolio strategy,  and performance  of
accounts;   and  effecting  securities  transactions  and  performing  functions
incidental thereto (such  as clearance and  settlement). Research and  brokerage
services  received from such brokers are in addition to, and not in lieu of, the
services required to be performed by the Manager under the investment management
and administration contract.  A commission paid  to such brokers  may be  higher
than  that which another  qualified broker would have  charged for effecting the
same transaction, provided that the Manager  determines in good faith that  such
commission  is reasonable in terms either  of that particular transaction or the
overall responsibility of the Manager to the Fund and its other clients and that
the total commissions paid  by the Fund  will be reasonable  in relation to  the
benefit  it received over the long term.  Research services may also be received
from dealers who execute Fund transactions in OTC markets.
    
 
The Manager  may  allocate brokerage  transactions  to broker/dealers  who  have
entered  into arrangements under which the  broker/dealer allocates a portion of
the commissions paid by the Fund toward payment of the Fund's expenses, such  as
transfer agent and custodian fees.
 
Investment  decisions for the Fund and  for other investment accounts managed by
the Manager  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 Manager
believes that coordination and the ability to participate in volume transactions
will be beneficial to the Fund.
 
Under a policy adopted by the Company's  Board of Directors, and subject to  the
policy   of  obtaining  the  best  net  results,  the  Manager  may  consider  a
broker/dealer's sale of the shares of the Fund and the other funds for which the
Manager serves as investment  manager in selecting brokers  and dealers for  the
execution  of portfolio transactions. This policy does not imply a commitment to
execute portfolio transactions  through all broker/dealers  that sell shares  of
the Fund and such other funds.
 
The   Fund   contemplates   purchasing  most   foreign   equity   securities  in
over-the-counter markets or stock  exchanges located in  the countries in  which
the  respective principal offices  of the issuers of  the various securities are
located, if that  is the best  available market. The  fixed commissions paid  in
connection  with most such foreign stock  transactions generally are higher than
negotiated commissions on  United States transactions.  There generally is  less
government supervision and
 
                  Statement of Additional Information Page 19
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
regulation  of foreign  stock exchanges and  brokers than in  the United States.
Foreign security settlements  may in  some instances  be subject  to delays  and
related administrative uncertainties.
 
Foreign  equity securities may  be held by the  Fund in the  form of ADRs, ADSs,
EDRs, CDRs or securities convertible into foreign equity securities. ADRs, ADSs,
EDRs and CDRs may be listed on stock exchanges, or traded in the OTC markets  in
the  United States or  Europe, as the  case may be.  ADRs, like other securities
traded in the United States, will be subject to negotiated commission rates. The
foreign and domestic debt securities and  money market instruments in which  the
Fund may invest generally are traded in the OTC markets.
 
The Fund contemplates that, consistent with the policy of obtaining the best net
results,  brokerage transactions may be conducted through certain companies that
are members of the Liechtenstein Global Trust. The Company's Board of  Directors
has  adopted procedures  in conformity  with Rule  17e-1 under  the 1940  Act to
ensure that all brokerage commissions paid to such affiliates are reasonable and
fair in  the  context of  the  market in  which  they are  operating.  Any  such
transactions  will be effected and related  compensation paid only in accordance
with applicable SEC regulations.
 
   
For the fiscal  years ended  October 31,  1997, 1996,  and 1995,  the Fund  paid
aggregate   brokerage   commissions   of   $463,307,   $257,953   and  $318,958,
respectively. For the  fiscal years ended  October 31, 1996  and 1997, the  Fund
paid  to  LGT  Bank  in Liechtenstein,  AG,  an  "affiliated"  broker, aggregate
brokerage commissions  of $16,898  and $12,262,  respectively, for  transactions
involving  purchases and sales  of portfolio securities  which represented 6.55%
and 2.65%, respectively, of the total brokerage commissions paid by the Fund and
5.69% and 2.94%, respectively,  of the aggregate  dollar amount of  transactions
involving payment of commissions by the Fund.
    
 
PORTFOLIO TRADING AND TURNOVER
   
The  Fund engages in portfolio  trading when the Manager  has concluded that the
sale of a security owned by the Fund and/ or the purchase of another security of
better value can  enhance principal and/or  increase income. A  security may  be
sold  to avoid  any prospective decline  in market  value, or a  security may be
purchased  in  anticipation  of  a  market  rise.  Consistent  with  the  Fund's
investment  objective, a  security also  may be  sold and  a comparable security
purchased coincidentally in order to take advantage of what is believed to be  a
disparity in the normal yield and price relationship between the two securities.
Although the Fund does not intend generally to trade for short-term profits, the
securities  in the Fund's portfolio will be sold whenever management believes it
is appropriate to  do so,  without regard  to the  length of  time a  particular
security  may have been held. Portfolio  turnover rate is calculated by dividing
the lesser of sales or purchases  of portfolio securities by the Fund's  average
month-end  portfolio  values,  excluding short-term  investments.  The portfolio
turnover rate will  not be a  limiting factor when  the Manager deems  portfolio
changes  appropriate. Higher portfolio turnover involves correspondingly greater
brokerage commissions  and  other transaction  costs  that the  Fund  will  bear
directly,  and  may result  in the  realization  of net  capital gains  that are
taxable when distributed to the Fund's shareholders. For the fiscal years  ended
October 31, 1997 and 1996, the Fund's portfolio turnover rates were 50% and 39%,
respectively.

INVESTMENT MANAGEMENT AND ADMINISTRATION SERVICES
The  Manager serves as the Fund's  investment manager and administrator under an
Investment  Management  and  Administration  Contract  ("Management   Contract")
between  the Company and  the Manager. As  investment manager and administrator,
the Manager makes  all investment  decisions for  the Fund  and administers  the
Fund's  affairs. Among other things, the Manager furnishes the services and pays
the compensation  and travel  expenses  of persons  who perform  the  executive,
administrative,  clerical and bookkeeping functions of the Company and the Fund,
and provides  suitable  office  space,  necessary  small  office  equipment  and
utilities.  For these services, the Fund  pays the Manager investment management
and administration fees, based on the Fund's average daily net assets,  computed
daily  and  paid monthly,  at the  annualized rate  of .975%  on the  first $500
million, .95% on the next $500 million, .925% on the next $500 million, and .90%
on amounts thereafter.
 
The Management Contract  may be renewed  for one-year terms,  provided that  any
such  renewal  has been  specifically  approved at  least  annually by:  (i) the
Company's Board  of Directors,  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 Directors  who are  not parties  to the  Management Contract  or  "interested
persons"  of any such  party (as defined in  the 1940 Act), cast  in person at a
meeting called  for  the  specific  purpose of  voting  on  such  approval.  The
Management  Contract provides that with respect to  the Fund, the Company or the
Manager may  terminate the  Contract without  penalty upon  sixty days'  written
notice.  The Management  Contract terminates automatically  in the  event of its
assignment (as defined in the 1940 Act).

DISTRIBUTION SERVICES
The  Fund's Class  A and  Class B  shares are  offered continuously  through the
Fund's principal underwriter  and distributor,  GT Global, on  a "best  efforts"
basis  pursuant to  a Distribution  Contract between  the Company  and GT Global
dated February 24, 1989.
 
As described in the Prospectus, the Company has adopted a separate  Distribution
Plan  with respect to each class of the Fund in accordance with Rule 12b-1 under
the 1940  Act  (the  "Class  A  Plan" and  "Class  B  Plan,"  respectively,  and
collectively,  "Plans"). The rate  of payments by  the Fund 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 Fund.  All expenses for
which GT Global is  reimbursed under the  Class A Plan  will have been  incurred
within  one year of such reimbursement. The  Fund makes no payments to any party
other than GT Global,  which is the distributor  (principal underwriter) of  the
Fund's  shares. The Class B Plan took  effect on October 22, 1992. The following
table discloses payments made by  the Fund to GT  Global under the Plans  during
the Fund's last fiscal year:

In  approving the Plans, the Directors determined that the adoption of each Plan
was in the best interests of  the shareholders of that Fund. Agreements  related
to  the Plans must also  be approved by such vote  of the Directors, including a
majority of  Directors 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  Directors review the  amounts
expended thereunder and the purposes for which such expenditures were made. Each
Plan  requires that so long  as it is in effect  the selection and nomination of

Directors who are not "interested persons"  of the Company will be committed  to
the discretion of the Directors who are not "interested persons" of the Company,
as defined in the 1940 Act.
 
As  discussed in the  Prospectus, GT Global  collects sales charges  on sales of
Class A shares of the Fund, retains certain amounts of such charges and reallows
other amounts of such  charges to broker/dealers  who sell shares.The  following
table  reviews the extent of  such activity during the  Fund's last three fiscal
years under  a sales  structure substantially  similar to  the current  Class  A
structure:

GT  Global receives any contingent deferred sales charges ("CDSCs") payable with
respect to redemptions of  Class B shares  and certain Class  A shares. For  the
fiscal years ended October 31, 1997, 1996 and 1995, GT Global collected CDSCs in
the amounts of $1,199,637, $1,485,113 and $1,552,827, 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 Manager serves as the Fund's pricing and accounting agent. For the
fiscal years ended October 31, 1997, October 31, 1996 and October 31, 1995,  the
Fund  paid accounting  services fees  to the  Manager of  $183,323, $162,035 and
$40,735, respectively.
    
 
EXPENSES OF THE FUND
The Fund pays  all expenses  not assumed  by the  Manager, GT  Global and  other
agents.  These  expenses include,  in  addition to  the  advisory, distribution,
transfer agency,  pricing and  accounting agency  and brokerage  fees  discussed
above, legal and audit expenses, custodian fees, directors' fees, organizational
fees,  fidelity bond and other insurance premiums, taxes, extraordinary expenses
and the expenses  of reports and  prospectuses sent to  existing investors.  The
allocation  of general 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. The ratio  of the Fund's expenses  to
its  relative net assets can be expected to be higher than the expense ratios of
funds investing solely in domestic securities, since the cost of maintaining the
custody of foreign securities and the rate of investment management fees paid by
the Fund generally are higher than the comparable expenses of such other funds.
 
- --------------------------------------------------------------------------------
 
                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
 
As described in the Prospectus,  the Fund's net asset  value per share for  each
class  of shares is determined  at 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
each business day the NYSE is open  for business. Currently, the NYSE is  closed
on  weekends and on certain days relating  to the following holidays: New Year's
Day,  Presidents'  Day,  Good  Friday,  Memorial  Day,  July  4th,  Labor   Day,
Thanksgiving Day and Christmas Day.
 
The Fund's portfolio securities and other assets are valued as follows:
 
Equity  securities, including  ADRs, ADSs, and  EDRs, which are  traded on stock
exchanges, are valued at the last sale price on the exchange or in the principal
over-the-counter market in which such securities are traded, as of the close  of
business  on the day the  securities are being valued  or, lacking any sales, at
the   last   available    bid   price.   In    cases   where   securities    are
 
                  Statement of Additional Information Page 24
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
traded  on more  than one  exchange, the securities  are valued  on the exchange
determined by the Manager to be the primary market.
 
Long-term debt obligations are valued at  the mean of representative quoted  bid
and  asked prices for such  securities or, if such  prices are not available, at
prices for securities of  comparable maturity, quality  and type; however,  when
the  Manager deems it appropriate, prices obtained for the day of valuation from
a bond pricing  service will be  used. Short-term investments  are amortized  to
maturity  based  on  their  cost,  adjusted  for  foreign  exchange translation,
provided such valuations represent fair value.
 
Options on indices, securities and currencies  purchased by the Fund are  valued
at  their last bid price  in the case of  listed options or, in  the case of OTC
options, at the average of  the last bid prices  obtained from dealers unless  a
quotation  from only one dealer  is available, in which  case only that dealer's
price will be used. The value of  each security denominated in a currency  other
than  U.S. dollars will be translated into U.S. dollars at the prevailing market
rate as  determined by  the Manager  on  that day.  When market  quotations  for
futures  and options on  futures held by  the Fund are  readily available, those
positions will be valued based upon such quotations.
 
Securities and  other  assets  for  which  market  quotations  are  not  readily
available  (including restricted securities which  are subject to limitations as
to their sale) are valued at fair value as determined in good faith by or  under
the  direction of  the Company's  Board of  Directors. The  valuation procedures
applied in any specific instance are likely to vary from case to case.  However,
consideration  generally is  given to the  financial position of  the issuer and
other fundamental analytical data relating to  the investment and to the  nature
of the restrictions on disposition of the securities (including any registration
expenses  that might be borne by the  Fund in connection with such disposition).
In addition, specific factors also generally are considered, such as the cost of
the investment, the  market value  of any  unrestricted securities  of the  same
class  (both at the time of purchase and  at the time of valuation), the size of
the holding, the  prices of any  recent transactions or  offers with respect  to
such securities and any available analysts' reports regarding the issuer.
 
The  fair value  of any  other assets is  added to  the value  of all securities
positions to  arrive  at  the value  of  the  Fund's total  assets.  The  Fund's
liabilities,  including  accruals  for  expenses, are  deducted  from  its total
assets. Once the total  value of the  Fund's net assets  is so determined,  that
value  is  then divided  by the  total number  of shares  outstanding (excluding
treasury shares), and the result, rounded to  the nearer cent, is the net  asset
value per share.
 
Any assets or liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars at the official exchange rate or at the mean of the
current  bid and asked  prices of such  currencies against the  U.S. dollar last
quoted by a major  bank that is  a regular participant  in the foreign  exchange
market  or on the basis of a pricing  service that takes into account the quotes
provided by a  number of such  major banks.  If none of  these alternatives  are
available, or none are deemed to provide a suitable methodology for converting a
foreign  currency into U.S. dollars, the Board of Directors, in good faith, will
establish a conversion rate for such currency.
 
European, Far Eastern, or Latin American  securities trading may not take  place
on  all days on which the NYSE is open. Further, trading takes place in Japanese
markets on certain Saturdays and in various foreign markets on days on which the
NYSE is not open. In addition, trading in securities on European and Far Eastern
securities exchanges  and OTC  markets generally  is completed  well before  the
close  of the  business day  in New York.  Consequently, the  calculation of the
Fund's  net  asset  value  may   not  take  place  contemporaneously  with   the
determination of the prices of securities held by the Fund. Events affecting the
values  of portfolio  securities that  occur between  the time  their prices are
determined and the close of regular trading on the NYSE will not be reflected in
the Fund's net  asset value  unless the Manager,  under the  supervision of  the
Company's  Board  of  Directors,  determines  that  the  particular  event would
materially affect net asset value. As a  result, the Fund's net asset value  may
be  significantly affected  by such  trading on  days when  a shareholder cannot
purchase or redeem shares of the Fund.

- --------------------------------------------------------------------------------
 
PAYMENT AND TERMS OF OFFERING
Payment for Class A  or Class B shares  purchased 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, on account of a check returned  for
"not  sufficient 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  at their then-current  net
asset  value per share  to reimburse the  Fund 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.
 
SALES OUTSIDE THE UNITED STATES
Sales of Fund shares made through brokers  outside the United States will be  at
net  asset value plus a sales commission,  if any, established by that broker or
by local law.  Such a commission,  if any, may  be more or  less than the  sales
charges listed in the sales charge table included in the Prospectus.
 
AUTOMATIC INVESTMENT PLAN -- CLASS A SHARES AND CLASS B SHARES
To  establish  participation in  the Fund's  Automatic Investment  Plan ("AIP"),
investors or their broker/dealers should  specify whether investment will be  in
Class  A  shares or  Class  B shares  and 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
included  at the back of the Fund's 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, a stop  payment order or 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.
 
LETTER OF INTENT -- CLASS A SHARES
   
A Letter of Intent ("LOI") is not a binding obligation to purchase the indicated
amount. While Class A shares are held  in escrow under an LOI to ensure  payment
of  applicable sales charges if  the indicated amount is  not met, all dividends
and other distributions on the escrowed shares will be reinvested in  additional
Class A shares or paid in cash, as specified by the shareholder. If the intended
investment  is  not completed  within the  specified thirteen-month  period, the
purchaser must  remit to  GT  Global the  difference  between the  sales  charge
actually  paid and the sales charge that would have been applicable if the total
Class A purchases had been made at a single time. If this amount is not paid  to
GT  Global within twenty  days after written request,  the appropriate number of
escrowed shares will be redeemed and the proceeds paid to GT Global.
    
 
A registered investment adviser,  trust company or  trust department seeking  to
execute  an LOI  as a single  purchaser with  respect to accounts  over which it
exercises investment discretion is required  to provide the Transfer Agent  with
information establishing that it has discretionary authority with respect to the
money invested (e.g., by providing a copy of the
 
                  Statement of Additional Information Page 26
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
pertinent  investment  advisory agreement).  Class  A shares  purchased  in this
manner must be registered  with the Transfer Agent  so that only the  investment
adviser,  trust company or trust department,  and not the beneficial owner, will
be able to place purchase, redemption and exchange orders.
 
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 Internal
Revenue Code of 1986, as amended  ("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 GT Global.
 
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 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
Shares  of the Fund  may be exchanged  for shares of  the corresponding class of
other GT Global Mutual Funds, based on their respective net asset values without
imposition  of  any  sales  charges,  provided  that  the  registration  remains
identical.  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 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
 
                  Statement of Additional Information Page 27
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
   
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  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.
    
 
SYSTEMATIC WITHDRAWAL PLAN
Shareholders owning Class A or  Class B shares 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 beginning quarterly on the 25th
day  of  the month  the investor  first selects).  If  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) also must  submit a "Corporation  Resolution" or "Certification  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.
 
With  respect to a SWP, 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. See
"How to Invest" in the Prospectus.
 
Shareholders should be aware that such systematic withdrawals may deplete or use
up entirely the initial investment and result in the realization of 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 thirty days' written notice or by a  shareholder
upon  written notice to the Fund or the Transfer Agent. Applications and further
details regarding establishment of a SWP are provided at the back of the  Fund's
Prospectus.
 
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, which makes it not reasonably practicable for the
Fund  to dispose of securities  owned by it or fairly  to determine 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  would, in  the
opinion of the Company's Board of Directors, 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. However,  despite the foregoing,  the Company has filed
with the SEC an election pursuant to  Rule 18f-1 under the 1940 Act. This  means
that  the  Fund  will  pay in  cash  all  requests for  redemption  made  by any
shareholder of record, limited in amount with respect to each shareholder during
any ninety-day period to the lesser of $250,000 or 1% of the net asset value  of
the  Fund at the beginning of such  period. This election will be irrevocable so
long as Rule 18f-1 remains in effect,  unless the SEC by order upon  application
permits the withdrawal of such election.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
GENERAL
To  continue to qualify for treatment  as a regulated investment company ("RIC")
under the Code, the  Fund must distribute to  its shareholders for each  taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income, net short-term capital gain and net gains from certain
foreign  currency  transactions)  ("Distribution  Requirement")  and  must  meet
several additional requirements. These  requirements include the following:  (1)
the  Fund must derive  at least 90% of  its gross income  each taxable year from
dividends, interest, payments with  respect to securities  loans and gains  from
the  sale or  other disposition  of securities  or foreign  currencies, or other
income (including gains from options, Futures or Forward Contracts) derived with
respect to its business of investing in securities or those currencies  ("Income
Requirement");  (2) at the close of each  quarter of the Fund's taxable year, at
least 50% of the value of its total assets must be represented by cash and  cash
items,   U.S.  government  securities,  securities   of  other  RICs  and  other
securities, with these other securities limited,  in respect of any one  issuer,
to an amount that does not exceed 5% of the value of the Fund's total assets and
that  does  not  represent more  than  10%  of the  issuer's  outstanding voting
securities; and (3) at the close of each quarter of the Fund's taxable year, not
more than 25% of  the value of  its total assets may  be invested in  securities
(other  than U.S. government securities or the  securities of other RICs) of any
one issuer.
 
Dividends and  other distributions  declared  by the  Fund  in, and  payable  to
shareholders  of record as  of a date  in, October, November  or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during  the following  January. Accordingly,  those distributions  will  be
taxed to shareholders for the year in which that December 31 falls.
 
A  portion of  the dividends from  the Fund's investment  company taxable income
(whether paid in cash  or reinvested in additional  shares) may be eligible  for
the  dividends-received deduction allowed to  corporations. The eligible portion
may  not  exceed  the  aggregate  dividends  received  by  the  Fund  from  U.S.
corporations.  However,  dividends  received  by  a  corporate  shareholder  and
deducted  by  it  pursuant  to  the  dividends-received  deduction  are  subject
indirectly to the alternative minimum tax.
 
If  Fund shares are sold at a loss after  being held for six months or less, the
loss will be treated  as long-term, instead of  short-term, capital loss to  the
extent  of any  capital gain distributions  received on  those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or other distribution, the shareholder will pay full price  for
the shares and receive some portion of the price back as a taxable distribution.
 
The  Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent it fails to distribute by the end of any calendar year substantially  all
of  its  ordinary income  for  that year  and capital  gain  net income  for the
one-year period ending on October 31 of that year, plus certain other amounts.
 
FOREIGN TAXES
   
Dividends and interest received by the Fund, and gains realized thereby, may  be
subject  to income, withholding or other  taxes imposed by foreign countries and
U.S. possessions  ("foreign taxes")  that would  reduce the  yield and/or  total
return  on its  securities. Tax  conventions between  certain countries  and the
United States may reduce or eliminate  foreign taxes, however, and many  foreign
countries  do not  impose taxes  on capital gains  in respect  of investments by
foreign investors. If more than 50% of  the value of the Fund's total assets  at
the  close of its  taxable year consists of  securities of foreign corporations,
the Fund  will be  eligible to,  and may,  file an  election with  the  Internal
Revenue  Service that  will enable its  shareholders, in effect,  to receive the
benefit of the foreign tax credit with respect to any foreign taxes paid by  it.
Pursuant  to the election, the Fund would treat those taxes as dividends paid to
its shareholders and each shareholder would be required to (1) include in  gross
income,  and treat as paid by him, his share of those taxes, (2) treat his share
of those taxes and of any dividend paid by the Fund that represents income  from
foreign  and U.S. possessions sources  as his own income  from those sources and
(3) either deduct the taxes deemed paid  by him in computing his taxable  income
or,  alternatively, use the foregoing information in calculating the foreign tax
credit against his federal income tax. The Fund will report to its  shareholders
shortly  after each taxable  year their respective shares  of the Fund's foreign
taxes and income from sources within  foreign countries and U.S. possessions  if
it makes this election. Pursuant to the Taxpayer Relief Act of 1997 ("Tax Act"),
individuals who have no more than $300 ($600 for married persons filing jointly)
of  creditable foreign  taxes included  on Form  1099 and  all of  whose foreign
source  income  is  "qualified  passive  income"  may  elect  each  year  to  be
    
 
                  Statement of Additional Information Page 29
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
exempt  from the extremely complicated foreign tax credit limitation and will be
able to claim a foreign tax credit without having to file the detailed Form 1116
that otherwise is required.
 
PASSIVE FOREIGN INVESTMENT COMPANIES
The Fund  may invest  in the  stock of  "passive foreign  investment  companies"
("PFICs").  A PFIC is a foreign corporation  -- other than a "controlled foreign
corporation" (I.E.,  a foreign  corporation  in which,  on  any day  during  its
taxable  year,  more than  50% of  the total  voting power  of all  voting stock
therein or the total value of  all stock therein is owned, directly,  indirectly
or  constructively, by  "U.S. shareholders," defined  as U.S.  persons that own,
directly, indirectly or constructively, at least 10% of that voting power) as to
which the Fund is a U.S.  shareholder (effective for its taxable year  beginning
November  1, 1998) -- that, in general, meets either of the following tests: (1)
at least 75% of its gross income is passive or (2) an average of at least 50% of
its assets produce,  or are held  for the production  of, passive income.  Under
certain  circumstances, the  Fund will  be subject  to federal  income tax  on a
portion of  any "excess  distribution" received  on,  or of  any gain  from  the
disposition  of, stock  of a  PFIC (collectively  "PFIC income"),  plus interest
thereon, even if the Fund distributes the  PFIC income as a taxable dividend  to
its  shareholders. The balance of the PFIC income will be included in the Fund's
investment company taxable income and, accordingly,  will not be taxable to  the
Fund to the extent it distributes that income to its shareholders.
 
If  the Fund  invests in a  PFIC and  elects to treat  the PFIC  as a "qualified
electing fund"  ("QEF"),  then  in  lieu  of  the  foregoing  tax  and  interest
obligation,  the Fund would be  required to include in  income each year its pro
rata share of the QEF's ordinary earnings and net capital gain (I.E., the excess
of net long-term capital  gain over net short-term  capital loss) -- which  most
likely  would have  to be  distributed by the  Fund to  satisfy the Distribution
Requirement and avoid imposition of the Excise Tax -- even if those earnings and
gain were not received by  the Fund from the QEF.  In most instances it will  be
very  difficult, if  not impossible,  to make  this election  because of certain
requirements thereof.
 
Effective for its taxable year beginning November 1, 1998, the Fund may elect to
"mark to market" its  stock in any PFIC.  "Marking-to-market," in this  context,
means  including in ordinary income each taxable year the excess, if any, of the
fair market value of the stock over the Fund's adjusted basis therein as of  the
end  of that year.  Pursuant to the election,  the Fund also  will be allowed to
deduct (as an ordinary, not capital, loss)  the excess, if any, of its  adjusted
basis  in  PFIC stock  over  the fair  market value  thereof  as of  the taxable
year-end, but only to the extent of any net mark-to-market gains with respect to
that stock included in income  by the Fund for  prior taxable years. The  Fund's
adjusted  basis in each PFIC's stock subject to the election will be adjusted to
reflect  the  amounts  of  income  included  and  deductions  taken  thereunder.
Regulations  proposed in 1992  would provide a similar  election with respect to
the stock of certain PFICs.
 
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 ("foreign  shareholder")  generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply, however, to a dividend paid by the Fund to a foreign
shareholder  that is "effectively connected with the  conduct of a U.S. trade or
business," in which case the  reporting and withholding requirements  applicable
to  domestic shareholders will apply. A distribution  of net capital gain by the
Fund to a foreign shareholder generally  will be subject to U.S. federal  income
tax  (at the rates applicable  to domestic persons) only  if the distribution is
"effectively connected"  or the  foreign shareholder  is treated  as a  resident
alien individual for federal income tax purposes.
 
OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS
The Fund's use of hedging transactions, such as selling (writing) and purchasing
options  and Futures and entering into Forward Contracts, involves complex rules
that will determine, for federal income tax purposes, the amount, character  and
timing  of recognition of the  gains and losses the  Fund realizes in connection
therewith. Gains  from the  disposition of  foreign currencies  (except  certain
gains  that  may be  excluded by  future regulations),  and gains  from options,
Futures and Forward Contracts derived by  the Fund with respect to its  business
of  investing in securities  or foreign currencies,  will qualify as permissible
income under the Income Requirement.
 
Futures and  Forward Contracts  that are  subject to  section 1256  of the  Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts") and  that are  held by  the  Fund at  the end  of its  taxable  year
generally  will be deemed to  have been sold at  market value for federal income
tax purposes. Sixty percent of any net  gain or loss recognized on these  deemed
sales, and 60% of any net gain or loss realized from any actual sales of Section
1256  Contracts, will  be treated  as long-term  capital gain  or loss,  and the
balance will be treated as  short-term capital gain or loss.  As of the date  of
preparation  of this  Statement of  Additional Information,  it is  not entirely
clear whether that 60% portion will qualify for the reduced maximum tax rates on
net capital gain enacted  by the Tax Act  -- 20% (10% for  taxpayers in the  15%
marginal  tax bracket) for gain recognized on  capital assets held for more than
18 months -- instead of  the 28% rate in  effect before that legislation,  which
now applies to gain recognized on capital assets held for more than one year but
not more than
 
                  Statement of Additional Information Page 30

                         GT GLOBAL GROWTH & INCOME FUND
18  months, although  technical corrections legislation  passed by  the House of
Representatives late in 1997 would treat it as qualifying therefor.
 
Section 988 of the Code also may apply to gains and losses from transactions  in
foreign  currencies, foreign-currency-denominated  debt securities  and options,
Futures and Forward  Contracts on  foreign currencies ("Section  988" gains  and
losses).  Each Section  988 gain  or loss  generally is  computed separately and
treated as ordinary income or loss. In the case of overlap between sections 1256
and 988, special provisions  determine the character and  timing of any  income,
gain  or loss. The Fund attempts to monitor section 988 transactions to minimize
any adverse tax impact.
 
If the Fund has  an "appreciated financial position"  -- generally, an  interest
(including  an interest through an option,  Futures or Forward Contract or short
sale) with respect to any stock, debt instrument (other than "straight debt") or
partnership interest the fair market value  of which exceeds its adjusted  basis
- --  and enters into a  "constructive sale" of the  same or substantially similar
property, the Fund will be treated as  having made an actual sale thereof,  with
the  result  that gain  will be  recognized  at that  time. A  constructive sale
generally consists of a short sale, an offsetting notional principal contract or
Futures or Forward Contract entered  into by the Fund  or a related person  with
respect  to  the same  or substantially  similar property.  In addition,  if the
appreciated financial  position is  itself  a short  sale  or such  a  contract,
acquisition of the underlying property or substantially similar property will be
deemed a constructive sale.
 
The  foregoing  is a  general  and abbreviated  summary  of certain  federal tax
considerations affecting 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 distributions
received from the Fund.

STANDARDIZED  RETURNS The Fund's  "Standardized Returns," as  referred to in the
Prospectus  (see  "Other   Information  --  Performance   Information"  in   the
Prospectus),  are calculated separately for  Class A, and Class  B shares of the
Fund, as follows:  Standardized Return  (average annual total  return ("T"))  is
computed  by using the ending redeeming  value ("ERV") 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 = ERV. The
following assumptions will be reflected in computations made in accordance  with
this  formula: (1) for Class A shares,  deduction of the maximum sales charge of
4.75% from the $1,000 initial investment;  (2) for Class B shares, deduction  of
the applicable contingent deferred sales charge imposed on a redemption of Class
B  shares  held  for  the  period;  (3)  reinvestment  of  dividends  and  other
distributions at net  asset value  on the  reinvestment date  determined by  the
Company's  Board of Directors; and  (4) a complete redemption  at the end of any
period illustrated.
 
The Standardized Returns for the Class A and Class B shares of the Fund,  stated
as average annualized total returns for the periods shown, were:

NON-STANDARDIZED  RETURNS In addition to Standardized Returns, the Fund may also
include in advertisements, sales literature and shareholder reports other  total
return  performance data ("Non-Standardized Return"). Non-Standardized Return is
calculated separately for  Class A and  Class B shares  of the Fund  and may  be
calculated according to several different formulas. Non-Standardized Returns may
be  quoted for the same or different time periods for which Standardized Returns
are quoted. Non-Standardized  Returns 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.
 
Average annual Non-Standardized  Return ("T")  is computed by  using the  ending
redeeming  value ("ERV")  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 =  ERV. The following  assumptions will be
reflected in computations made in accordance with this formula: (1) no deduction
of sales charges; (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.

IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKETS
The Fund  and  GT  Global  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 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.
 
        (2)  Data and mutual fund rankings and comparisons published or prepared
    by  Lipper  Analytical  Data  Services,  Inc.  ("Lipper"),  CDA/Wiesenberger
    Investment   Company   Services   ("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.
 
        (3)  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.
 
        (4)  Ibbotson  Associates  International Bond  Index,  which  provides a
    detailed breakdown of local market and currency returns since 1960.
 
        (5) Standard & Poor's 500 Composite Stock Price Index, which is a widely
    recognized index  composed of  the  capitalization-weighted average  of  the
    price of 500 of the largest publicly traded stocks in the U.S.
 
        (6) Dow Jones Industrial Average.
 
        (7) CNBC/Financial News Composite Index.
 
        (8) Morgan Stanley Capital International World Indices, including, among
    others, the Morgan Stanley Capital International Europe, Australia, Far East
    Index  ("EAFE Index").  The EAFE  index is an  unmanaged index  of more than
    1,000 companies in Europe, Australia and the Far East.
 
        (9) Morgan Stanley  Capital International All  Country (AC) World  index
    ("MSCI").  The  MSCI is  a broad,  unmanaged index  of global  stock prices,
    currently comprising 2500  different issuers, located  in 47 countries,  and
    grouped in 38 separate industries.

    and Development ("OECD").
 
       (22)  Average of  Savings Accounts,  which is a  measure of  all kinds of
    savings deposits, including longer-term certificates. Savings accounts offer
    a guaranteed rate  of return on  principal, but no  opportunity for  capital
    growth.  During a  portion of  the period,  the maximum  rates paid  on some
    savings deposits were fixed by law.
 
   
Indices, economic and  financial data  prepared by the  research departments  of

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, 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

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.
    
 
Information  relating  to   foreign  market   performance,  capitalization   and
diversification  is based on sources believed to  be reliable but may be subject
to revision and has not  been independently verified by  the Fund or GT  Global.
The  authors  and  publishers of  such  material  are not  to  be  considered as
"experts" under the 1933  Act, on account of  the inclusion of such  information
herein.
 
A  portion of the performance  figures for each market  includes the positive or
negative effects of the currency exchange rates effective at December 31 of each
year between the U.S. dollar and currency of the foreign market (e.g.,  Japanese
Yen,  German Deutschemark  and Hong  Kong Dollar).  A foreign  currency that has
strengthened or weakened against the  U.S. dollar will positively or  negatively
affect the reported returns, as the case may be.
 
GT  Global believes that this information may be useful to investors considering
whether and to what extent to diversify their investment through the purchase of
mutual funds investing in  securities on a global  basis. However, this data  is
not a representation of the past performance of the Fund, nor is it a prediction
of such performance. The performance of the Fund will differ from the historical
performance  or  relevant  indices. The  performance  of indices  does  not take
expenses

into account,  while the  Fund incurs  expenses in  its operations,  which  will
reduce performance. Each of these factors will cause the performance of the Fund
to differ from relevant indices.
 
From  time  to  time,  the  Fund  and GT  Global  may  refer  to  the  number of
shareholders in  the Fund  or the  aggregate number  of shareholders  in all  GT
Global  Mutual Funds  or the  dollar amount of  Fund assets  under management or

GT  Global  believes  the  Fund  is  an  appropriate  investment  for  long-term
investment   goals,  including  funding  retirement,  paying  for  education  or
purchasing  a  house.  GT  Global  may  provide  information  designed  to  help
individuals  understand  their investment  goals  and explore  various financial
strategies. For example, GT Global may describe general principles of investing,
such as asset allocation, diversification and risk tolerance. The Fund does  not
represent  a complete investment  program and the  investors should consider the
Fund as appropriate  for a portion  of their overall  investment portfolio  with
regard  to their long-term investment goals. There is no assurance that any such
information will lead to achieving these goals or guarantee future results.
 
From time to time,  GT Global may refer  to or advertise the  names of U.S.  and
non-U.S.  companies and their products, although  there can be no assurance that
any GT Global Mutual Fund may own the securities of these companies.
 
   
Ibbotson  Associates  of  Chicago,  Illinois  ("Ibbotson")  provides  historical
returns  of the capital  markets in the United  States, including common stocks,
small  capitalization  stocks,  long-term  corporate  bonds,   intermediate-term
government  bonds, long-term government bonds, Treasury  bills, the U.S. rate of
inflation (based on the CPI), and  combinations of various capital markets.  The

indices.
    
 
GT Global Mutual Funds may use the performance of these capital markets in order
to demonstrate  general  risk-versus-reward  investment  scenarios.  Performance
comparisons  may also include the  value of a hypothetical  investment in any of
these capital  markets. The  risks associated  with the  security types  in  any
capital market may or may not correspond directly to those of the Fund. Ibbotson
calculates total returns in the same method as the 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 historical share price fluctuations or total return to those
of a benchmark.
    
 
The Fund may  advertise examples of  the effects of  periodic investment  plans,
including the principle of dollar cost averaging programs. 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 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."
 
GT Global may from time to time in its sales methods and advertising discuss the
risks inherent in investing. The major types of investment risk are market risk,
industry  risk,  credit  risk,  interest  rate  risk  and  inflation  risk. Risk
represents the possibility that you may lose some or all of your investment over
a period  of time.  A basic  tenet of  investing is  the greater  the  potential
reward, the greater the risk.
 
From  time to  time, the  Fund and  GT Global  will quote  information regarding
industries, individual countries, regions,  world stock exchanges, and  economic

From time  to  time, GT  Global  may include  in  its advertisements  and  sales
material,   information  about  privatization,  which  is  an  economic  process
involving the sale of state-owned companies to the private sector.
    
 
   
In advertising and sales materials, GT  Global may make reference to or  discuss
its products, services and accomplishments. Among these accomplishments are that
in  1983  the Manager  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 Manager 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 Manager  provide any  assurance
that the GT Global Mutual Funds' investment objectives will be achieved.
    
 
   
GT GLOBAL ADVANTAGE
    
   
As  part of Liechtenstein Global Trust,  GT Global continues a 75-year tradition
of  service  to  individuals  and  institutions.  Today  we  bring  investors  a
combination of experience, worldwide resources, a global perspective, investment
talent and a time-tested investment discipline. With investment professionals in
nine  offices  worldwide,  we  witness world  events  and  economic developments
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.
    
 
   
Built-in  checks  and balances  strengthen  the process,  enhancing professional
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. With respect to stocks, a global  stock
research  ("GSR") database developed  by GT Global is  utilized in the selection
process. All stocks  within the GSR  database are systematically  ranked by  our
analysts  on a  1-5 basis  with 1 representing  the most  favored. The rankings,
along with our  quantitative, fundamental research,  determine which stocks  are
bought and sold.
    
 
GT  Global describes the major stages of  economic development as revolving in a
"virtuous cycle." From time  to time, each  Fund and GT  Global may discuss  the
virtuous  cycle in  its sales  literature and  advertising. This  cycle operates
worldwide,  forcing  companies   to  become  increasingly   competitive  in   an
ever-expanding  global  marketplace.  GT  Global  has  identified  the following
sequential stages within the virtuous cycle:
 
FALLING  BORDERS  AND  TRADE  BARRIERS:  Barriers  between  countries  diminish,
increasing the potential for world trade and promoting global competition.
 
CAPITAL  FLOWS FROM  DEVELOPED MARKETS  TO EMERGING  MARKETS: As  barriers fall,
restrictions on the free movement of capital  in and out of a country are  often
reduced or removed. The flow of money from developed to developing markets gains
momentum.
 
INDUSTRIALIZATION OF EMERGING MARKETS: With capital flowing across borders, many
developing nations are able to quickly begin their process of industrialization.
 
INCREASED  DEMAND FOR  GLOBAL CONSUMER PRODUCTS:  As people  in emerging markets
experience rising standards of living  due to increased industrialization,  they
demand more consumer products which can help spur global trade flows.
 
   
GT  Global believes that we  increasingly live in a  world without boundaries in
terms of trade, competition and  investment opportunities. Therefore, GT  Global
believes it's becoming more relevant to look at investing in terms of industrial
groupings,  or themes,  as an alternative  to the traditional,  primary focus on
regions. GT Global believes such themes make movement possible between stages in
the virtuous cycle of economic progress.

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

Note:  Moody's applies numerical  modifiers, 1, 2  and 3 in  each generic rating
classification from Aa to Caa. The  modifier 1 indicates that the Company  ranks
in  the higher end  of its generic  rating category; the  modifier 2 indicates a
mid-range ranking; and the  modifier 3 indicates that  the Company ranks in  the
lower end of its generic rating category.
 
    STANDARD  & POOR'S, a  division of The  McGraw-Hill Companies, Inc. ("S&P"),
rates the securities debt of various  entities in categories ranging from  "AAA"
to  "D"  according  to quality.  Investment  grade  ratings are  the  first four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA  --  An  obligation  rated  "AA"  differs  from  the  highest   rated
    obligations  only  in a  small degree.  The obligor's  capacity to  meet its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB  --  An   obligation  rated  "BBB"   exhibits  adequate   protection
    parameters.  However, adverse economic  conditions or changing circumstances
    are more likely to lead  to a weakened capacity of  the obligor to meet  its
    financial commitment on the obligation.
 
        BB,  B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and "C"
    are  regarded  as  having  significant  speculative  characteristics.   "BB"
    indicates  the least degree  of speculation and "C"  the highest. While such
    obligations will likely  have some quality  and protective  characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB  -- An  obligation rated "BB"  is less vulnerable  to nonpayment than
    other speculative issues. However, it  faces major ongoing uncertainties  or
    exposure  to adverse business, financial, or economic conditions which could
    lead to the obligor's inadequate  capacity to meet its financial  commitment
    on the obligation.
 
        B  --  An obligation  rated "B"  is more  vulnerable to  nonpayment than
    obligations rated "BB," but the obligor  currently has the capacity to  meet
    its  financial commitment on the obligation. Adverse business, financial, or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC -- An obligation rated "CCC" is currently vulnerable to  nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for  the obligor to meet its financial  commitment on the obligation. In the
    event of adverse business, financial, or economic conditions, the obligor is
    not likely to  have the  capacity to meet  its financial  commitment on  the
    obligation.
 
        CC  --  An  obligation  rated "CC"  is  currently  highly  vulnerable to
    nonpayment.
 
   
        C -- The "C" rating may be used to cover a situation where a  bankruptcy
    petition  has been filed or  similar action has been  taken, but payments on
    this obligation are being continued.
    
 
        D --  An obligation  rated "D"  is in  payment default.  The "D"  rating
    category is used when payments on an obligation are not made on the date due
    even  if the  applicable grace period  has not expired,  unless S&P believes
    that such payments  will be made  during such grade  period. The "D"  rating
    also  will be used upon the filing of a bankruptcy petition or the taking of
    a similar action if payments on an obligation are jeopardized.
 
PLUS (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by  the
addition  of a  plus or minus  sign to  show relative standing  within the major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient  information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S employs  the  designation  "Prime-1" to  indicate  commercial  paper
having  a superior ability for repayment  of senior short-term debt obligations.
Prime-1 repayment  ability will  often be  evidenced by  many of  the  following
characteristics:  leading market positions  in well-established industries; high
rates of return  on funds employed;  conservative capitalization structure  with
moderate  reliance on debt and ample asset protection; broad margins in earnings
coverage of  fixed financial  charges  and high  internal cash  generation;  and
well-established  access to a range of  financial markets and assured sources of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior short-term debt obligations. This normally  will be evidenced by many  of
the  characteristics cited  above but  to a  lesser degree.  Earnings trends and
coverage ratios, while sound, may  be more subject to variation.  Capitalization
characteristics,  while  still appropriate,  may  be more  affected  by external
conditions. Ample alternate liquidity is maintained.
 
                  Statement of Additional Information Page 39
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
    S&P ratings of commercial paper  are graded into several categories  ranging
from  "A1" for the highest quality obligations  to "D" for the lowest. Issues in
the "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate  the
relative  degree  of safety.  A-1 --  This highest  category indicates  that the
degree of safety regarding timely payment is strong. Those issues determined  to
possess extremely strong safety characteristics will be denoted with a plus sign
(+)  designation.  A-2  -- Capacity  for  timely  payments on  issues  with this
designation is satisfactory; however,  the relative degree of  safety is not  as
high as for issues designated "A-1."

ANNUAL REPORT
To the Shareholders of GT Global Growth & Income Fund and Board of Directors of
G.T. Investment Funds, Inc.:
 
We have audited the accompanying statement of assets and liabilities of GT
Global Growth & Income Fund, one of the funds organized as a series of G.T.
Investment Funds, Inc., including the portfolio of investments, as of October
31, 1997, the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended. These financial statements and the financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
October 31, 1997, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
In our opinion, the financial statements and the financial highlights referred
to above present fairly, in all material respects, the financial position of GT
Global Growth & Income Fund as of October 31, 1997, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with generally accepted
accounting principles.

portfolio of investments.
 
The Fund offers Class A, Class B, and Advisor Class shares, each of which has
equal rights as to assets and voting privileges. Class A and Class B each has
exclusive voting rights with respect to its distribution plan. Investment
income, realized and unrealized capital gains and losses, and the common
expenses of the Fund are allocated on a pro rata basis to each class based on
the relative net assets of each class to the total net assets of the Fund. Each
class of shares differs in its respective service and distribution expenses, and
may differ in its transfer agent, registration, and certain other class-specific
fees and expenses.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies in conformity with generally accepted accounting
principles consistently followed by the Funds in the preparation of the
financial statements.
 
(A) PORTFOLIO VALUATION
The Fund calculates the net asset value of and completes orders to purchase,
exchange or repurchase Fund shares on each business day, with the exception of
those days on which the New York Stock Exchange is closed.
 
Equity securities are valued at the last sale price on the exchange on which
such securities are traded, or on the principal over-the-counter market on which
such securities are traded, as of the close of business on the day the
securities are being valued, or, lacking any sales, at the last available bid
price. In cases where securities are traded on more than one exchange, the
securities are valued on the exchange determined by, Chancellor LGT Asset
Management, Inc. ("the Manager") to be the primary market.
 
Fixed income investments are valued at the mean of representative quoted bid and
ask prices for such investments or, if such prices are not available, at prices
for investments of comparative maturity, quality and type; however, when the
Fund deems it appropriate, prices obtained for the day of valuation from a bond
pricing service will be used. Short-term investments are valued at amortized
cost adjusted for foreign exchange translation and market fluctuations, if any.
 
Investments for which market quotations are not readily available (including
restricted securities which are subject to limitations on their sale) are valued
at fair value as determined in good faith by or under the direction of the
Company's Board of Directors.
 
Portfolio securities which are primarily traded on foreign exchanges are
generally valued at the preceding closing values of such securities on their
respective exchanges, and those values are then translated into U.S. dollars at
the current exchange rates, except that when an occurrence subsequent to the
time a value was so established is likely to have materially changed such value,
then the fair value of those securities will be determined by consideration of
other factors by or under the direction of the Company's Board of Directors.
 
(B) FOREIGN CURRENCY TRANSLATION
The accounting records of the Fund are maintained in U.S. dollars. The market
values of foreign securities, currency holdings, and other assets and
liabilities are recorded in the books and records of the Fund after translation
to U.S. dollars based on the exchange rates on that day. The cost of each
security is determined using historical exchange rates. Income and withholding
taxes are translated at prevailing exchange rates when earned or incurred.
 
The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.
 
Reported net realized foreign exchange gains or losses arise from sales and
maturities of short-term securities, forward foreign currency contracts, sales
of foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
value of assets and liabilities other than investments in securities at year
end, resulting from changes in exchange rates.
 
(C) REPURCHASE AGREEMENTS
With respect to repurchase agreements entered into by the Fund, it is the Fund's
policy to always receive, as collateral, United States government securities or
other high quality debt securities of which the value, including accrued
interest, is at least equal to the amount to be repaid to the Fund under each
agreement at its maturity.
 
(D) FORWARD FOREIGN CURRENCY CONTRACTS
A forward foreign currency contract ("Forward Contract") is an agreement between
two parties to buy and sell a currency at a set price on a future date. The
market value of the Forward Contract
 
                                      F14
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
fluctuates with changes in currency exchange rates. The Forward Contract is
marked-to-market daily and the change in market value is recorded by the Fund as
an unrealized gain or loss. When the Forward Contract is closed, the Fund
records a realized gain or loss equal to the difference between the value at the
time it was opened and the value at the time it was closed. Forward Contracts
involve market risk in excess of the amounts shown in the Fund's "Statement of
Assets and Liabilities." The Fund could be exposed to risk if a counter party is
unable to meet the terms of the contract or if the value of the currency changes
unfavorably. The Fund may enter into Forward Contracts in connection with
planned purchases or sales of securities, or to hedge against adverse
fluctuations in exchange rates between currencies.
 
(E) OPTION ACCOUNTING PRINCIPLES
When the Fund writes a call or put option, an amount equal to the premium
received is included in the Fund's "Statement of Assets and Liabilities" as an
asset and an equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current market value of the option. The current
market value of an option listed on a traded exchange is valued at its last bid
price, or, in the case of an over-the-counter option, is valued at the average
of the last bid prices obtained from brokers. If an option expires on its
stipulated expiration date or if the Fund enters into a closing purchase
transaction, a gain or loss is realized without regard to any unrealized gain or
loss on the underlying security, and the liability related to such option is
extinguished. If a written call option is exercised, a gain or loss is realized
from the sale of the underlying security and the proceeds of the sale are
increased by the premium originally received. If a written put option is
exercised, the cost of the underlying security purchased would be decreased by
the premium originally received. The Fund can write options only on a covered
basis, which, for a call, requires that the Fund hold the underlying security
and, for a put, requires the Fund to set aside cash, U.S. government securities,
or other liquid, high grade debt securities in an amount not less than the
exercise price or otherwise provide adequate cover at all times while the put
option is outstanding. The Fund may use options to manage its exposure to the
stock or bond market and to fluctuations in currency values or interest rates.
 
The premium paid by the Fund for the purchase of a call or put option is
included in the Fund's "Statement of Assets and Liabilities" as an investment
and subsequently "marked-to-market" to reflect the current market value of the
option. If an option which the Fund has purchased expires on the stipulated
expiration date, the Fund realizes a loss in the amount of the cost of the
option. If the Fund enters into a closing sale transaction, the Fund realizes a
gain or loss, depending on whether proceeds from the closing sale transaction
are greater or less than the cost of the option. If the Fund exercises a call
option, the cost of the securities acquired by exercising the call is increased
by the premium paid to buy the call. If the Fund exercises a put option, it
realizes a gain or loss from the sale of the underlying security, and the
proceeds from such sale are decreased by the premium originally paid.
 
The risk associated with purchasing options is limited to the premium originally
paid. The risk in writing a call option is that the Fund may forego the
opportunity of profit if the market value of the underlying security or index
increases and the option is exercised. The risk in writing a put option is that
the Fund may incur a loss if the market value of the underlying security or
index decreases and the option is exercised. In addition, there is the risk the
Fund may not be able to enter into a closing transaction because of an illiquid
secondary market.
 
(F) FUTURES CONTRACTS
A futures contract is an agreement between two parties to buy and sell a
security at a set price on a future date. Upon entering into such a contract the
Fund is required to pledge to the broker an amount of cash or securities equal
to the minimum "initial margin" requirements of the exchange on which the
contract is traded. Pursuant to the contract, the Fund agrees to receive from or
pay to the broker an amount of cash equal to the daily fluctuation in value of
the contract. Such receipts or payments are known as "variation margin" and are
recorded by the Fund as unrealized gains or losses. When the contract is closed,
the Fund records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the time it was
closed. The potential risk to the Fund is that the change in value of the
underlying securities may not correlate to the change in value of the contracts.
The Fund may use futures contracts to manage its exposure to the stock or bond
market and to fluctuations in currency values or interest rates.
 
(G) SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME
Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). The cost of securities sold is determined on a first-in,
first-out basis, unless otherwise specified. Dividends are recorded on the
ex-dividend date. Interest income is recorded on the accrual basis. Where a high
level of uncertainty exists as to collection, income is recorded net of all
withholding tax with any rebate recorded when received. The Fund may trade
securities on other than normal settlement terms. This may increase the risk if
the other to the transaction fails to deliver and causes the Fund to
subsequently invest at less advantageous prices.
 
(H) PORTFOLIO SECURITIES LOANED
At October 31, 1997, stocks with an aggregate value of approximately $51,986,675
were on loan to brokers. The loans were secured by cash collateral of
$54,846,747. For international securities, cash collateral is received by the
Fund against loaned securities in an amount at least equal to 105% of the market
value of the loaned securities at the inception of each loan. This collateral
must be maintained at not less than 103% of the market value of the loaned
securities during the period of the loan. For domestic securities, cash
collateral is received by the Fund against loaned securities in an amount at
least equal to 102% of the market value of the loaned securities at the
inception of each loan. This collateral must be maintained at not less than 100%
of the market value of the loaned securities during the period of the loan. For
the year ended October 31, 1997, the Fund
 
                                      F15
<PAGE>
                         GT GLOBAL GROWTH & INCOME FUND
 
received $976,164 of income from securities lending which was used to offset the
Fund's custody and administrative expenses.
 
(I) TAXES
It is the policy of the Fund to meet the requirements for qualification as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended ("Code"). It is also the intention of the Fund to make distributions
sufficient to avoid imposition of any excise tax under Section 4982 of the Code.
Therefore, no provision has been made for Federal taxes on income, capital
gains, or unrealized appreciation of securities held, and excise tax on income
and capital gains.
 
(J) DISTRIBUTIONS TO SHAREHOLDERS
Distributions to shareholders are recorded by the Fund on the ex-date. Income
and capital gain distributions are determined in accordance with Federal income
tax regulations which may differ from generally accepted accounting principles.
These differences are primarily due to differing treatments of income and gains
on various investment securities held by the Fund and timing differences.
 
(K) FOREIGN SECURITIES
There are certain additional considerations and risks associated with investing
in foreign securities and currency transactions that are not inherent in
investment of domestic origin. The Fund's investments in emerging market
countries may involve greater risks than investments in more developed markets
and the price of such investments may be volatile. These risks of investing in
foreign and emerging markets may include foreign currency exchange rate
fluctuations, perceived credit risk, adverse political and economic developments
and possible adverse foreign government intervention.
 
(L) INDEXED SECURITIES
The Fund may invest in indexed securities whose value is linked either directly
or indirectly to changes in foreign currencies, interest rates, equities,
indices, or other reference instruments. Indexed securities may be more volatile
than the reference instrument itself, but any loss is limited to the amount of
the original investment.
 
(M) RESTRICTED SECURITIES
The Fund is permitted to invest in privately placed restricted securities. These
securities may be resold in transactions exempt from registration or to the
public if the securities are registered. Disposal of these securities may
involve time-consuming negotiations and expense, and prompt sale at an
acceptable price may be difficult.
 
(N) LINE OF CREDIT
The Fund, along with certain other funds ("GT Funds") advised or administered by
the Manager, has a line of credit with each of BankBoston and State Street Bank
& Trust Company. The arrangements with the banks allow the Fund and the GT Funds
to
borrow an aggregate maximum amount of $200,000,000. The Fund is limited to
borrowing up to 33 1/3% of the value of each Fund's total assets. On October 31,
1997, the Fund had no loan outstanding.
 
For the year ended October 31, 1997, the weighted average outstanding daily
balance of bank loans (based on the number of days the loans were outstanding)
for the Fund was $2,560,909, with a weighted average interest rate of 6.41%.
Interest expense for the Fund for the year ended October 31, 1997 was $5,014,
included in "Other Expenses" on the Statement of Operations.
 
2. RELATED PARTIES
Chancellor LGT Asset Management, Inc., is the Funds' investment manager and
administrator. The Fund pays investment management and administration fees to
the Manager at the annualized rate of 0.975% on the first $500 million of
average daily net assets of the Fund; 0.95% on the next $500 million; 0.925% on
the next $500 million and 0.90% on amounts thereafter. These fees are computed
daily and paid monthly.
 
GT Global , Inc. ("GT Global"), an affiliate of the Manager, serves as the
Fund's distributor. The Fund offers Class A, Class B, and Advisor Class shares
for purchase.
 
Class A shares are subject to initial sales charges imposed at the time of
purchase, in accordance with the schedule included in the Fund's current
prospectus. GT Global collects the sales charges imposed on sales of Class A
shares, and reallows a portion of such charges to dealers through which the
sales are made. For the year ended October 31, 1997, GT Global retained $52,850
of such sales charges. Purchases of Class A shares exceeding $500,000 may be
subject to a contingent deferred sales charge ("CDSC") upon redemption, in
accordance with the Fund's current prospectus. GT Global collected CDSCs in the
amount of $32 for the year ended October 31, 1997. GT Global also makes ongoing
shareholder servicing and trail commission payments to dealers whose clients
hold Class A shares.
 
Class B shares are not subject to initial sales charges. When Class B shares are
sold, GT Global from its own resources pays commissions to dealers through which
the sales are made. Certain redemptions of Class B shares made within six years
of purchase are subject to CDSCs, in accordance with the Fund's current
prospectus. For the year ended October 31, 1997 GT Global collected CDSCs in the
amount of $1,199,605. In addition, GT Global makes ongoing shareholder servicing
and trail commission payments to dealers whose clients hold Class B shares.
 
Pursuant to Rule 12b-1 under the 1940 Act, the Company's Board of Directors has
adopted separate distribution plans with respect to the Fund's Class A shares
("Class A Plan") and Class B shares ("Class B Plan"), pursuant to which the Fund
reimburses GT Global for a portion of its shareholder servicing and distribution
expenses. Under the Class A Plan, the Fund may pay GT Global a service fee at
the annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class A shares for GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and may pay GT Global a distribution fee at
the annualized rate of up to 0.35% of the average daily net assets of the Fund's
Class A shares, less any amounts paid by the Fund as the aforementioned service
fee, for GT Global's expenditures incurred in providing services as distributor.
All expenses for which GT Global is reimbursed under the Class A Plan will have
been incurred within one year of such reimbursement.

                         GT GLOBAL GROWTH & INCOME FUND
 
Pursuant to the Fund's Class B Plan, the Fund may pay GT Global a service fee at
the annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class B shares for GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and may pay GT Global a distribution fee at
the annualized rate of up to 0.75% of the average daily net assets of the Fund's
Class B shares for GT Global's expenditures incurred in providing services as
distributor. Expenses incurred under the Class B Plan in excess of 1.00%
annually may be carried forward for reimbursement in subsequent years as long as
that Plan continues in effect.
 
The Manager and GT Global voluntarily have undertaken to limit the Fund's
expenses (exclusive of brokerage commissions, taxes, interest, and extraordinary
expenses) to the maximum annual rate of 1.85%, 2.50%, and 1.50% of the average
daily net assets of the Fund's Class A, Class B, and Advisor Class shares,
respectively. If necessary, this limitation will be effected by waivers by the
Manager of investment management and administration fees, waivers by GT Global
of payments under the Class A Plan and/or Class B Plan and/ or reimbursements by
the Manager or GT Global of portions of the Fund's other operating expenses.
 
Effective November 1, 1997, the Manager and GT Global have undertaken to limit
each Fund's expenses (exclusive of brokerage commissions, taxes, interest, and
extraordinary expenses) to the annual rate of 1.75%, 2.40% and 1.40% of the
average daily net assets of the Fund's Class A, Class B and Advisor Class
shares, respectively. This undertaking may be changed or eliminated in the
future.
 
GT Global Investor Services, Inc. ("GT Services"), an affiliate of the Manager
and GT Global, is the transfer agent of the Fund. For performing shareholder
servicing, reporting, and general transfer agent services, GT Services 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. GT Services 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 Manager is the pricing and accounting agent for the Fund. The monthly fee
for these services to the Manager is a percentage, not to exceed 0.03% annually,
of the Fund's average daily net assets. The annual fee rate is derived by
applying 0.03% to the first $5 billion of assets of all registered mutual funds
advised by the Manager and 0.02% to the assets in excess of $5 billion and
allocating the result according to the Fund's average daily net assets.
 
The Company pays each of its Directors who is not an employee, officer or
director of the Manager, GT Global or GT Services $5,000 per year plus $300 for
each meeting of the board or any committee thereof attended by the Director.
