                          PROSPECTUS -- MARCH 1, 1998
- --------------------------------------------------------------------------------
 
GT GLOBAL DEVELOPING MARKETS FUND (THE "FUND") primarily seeks long-term capital
appreciation. Its secondary investment objective is income, to the extent
consistent with seeking capital appreciation. The Fund normally invests
substantially all of its assets in issuers in the developing (or "emerging")
markets of Asia, Europe, Latin America and elsewhere. A majority of the Fund's
assets ordinarily is invested in emerging market equity securities. The Fund
also invests in emerging market debt securities, which are selected based on
their potential to provide a combination of capital appreciation and current
income. There can be no assurance that the Fund will achieve its investment
objectives.
 
The Fund is managed by Chancellor LGT Asset Management, Inc. (the "Manager").
The Manager and its worldwide affiliates are part of Liechtenstein Global Trust,
a provider of global asset management and private banking products and services
to individual and institutional investors.
 
The Fund is designed for long-term investors and not as a trading vehicle. The
Fund does not represent a complete investment program, nor is it suitable for
all investors. The Fund may invest significantly in equity and high yield, high
risk ("lower quality") debt securities that are predominantly speculative.
Investments of this type are subject to a greater risk of loss of principal and
interest. The Fund's investments in securities of issuers in developing markets
involves special considerations and risks that are not typically associated with
investments in securities of issuers in the United States or in other more
established markets. Investors should carefully assess the risks associated with
an investment in the Fund.

investing and should be read carefully and retained for future reference. A

                               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. (the
                                                "Company").
 
Investment Objectives:         The Fund's  primary  investment  objective  is  long-term  capital
                               appreciation;  its secondary  objective is  income, to  the extent
                               consistent with seeking capital appreciation.
 
Principal Investments:         The Fund normally  invests a  majority of its  assets in  emerging
                               market  equity securities and  also may invest  in emerging market
                               debt securities.
 
Principal Risk Factors:        There is no assurance  that the Fund  will achieve its  investment
                               objectives.  The Fund's net asset  value per share will fluctuate,
                               reflecting fluctuations  in  the  market value  of  its  portfolio
                               holdings.
 
                               The  Fund invests  in foreign  securities. Investments  in foreign
                               securities  involve  risks  relating  to  political  and  economic
                               developments abroad and the differences between the regulations to
                               which  U.S. and  foreign issuers  are subject.  Individual foreign
                               economies also may differ favorably  or unfavorably from the  U.S.
                               economy.  Changes in  foreign currency exchange  rates will affect
                               the Fund's  net  asset  value,  earnings,  and  gains  and  losses
                               realized  on sales of securities.  Securities of foreign companies
                               may be less liquid  and their prices more  volatile than those  of
                               securities of comparable U.S. companies. The Fund normally invests
                               substantially  all of its  assets in issuers  in emerging markets.
                               Such investments entail greater risks than investing in issuers in
                               developed markets.
 
                               The Fund  may  engage in  certain  foreign currency,  options  and
                               futures transactions to attempt to hedge against the overall level
                               of  investment and  currency risk  associated with  its present or
                               planned investments. Such transactions  involve certain risks  and
                               transaction costs.
 
                               The value of debt securities held by the Fund generally fluctuates
                               inversely  with interest rate  movements. Certain investment grade
                               debt securities may  possess speculative qualities.  The Fund  may
                               invest  in below investment grade  debt securities. Investments of
                               this type are subject to a  greater risk of loss of principal  and
                               interest.
 
                               See "Investment Objectives and Policies" and "Risk Factors."
 
Investment Manager:            The  Manager is part of Liechtenstein  Global Trust, a provider of

                               to   individual  and   institutional  investors,   entrusted  with

- ------------------
(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 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 regulations
    of the SEC applicable to all mutual funds. The 5% annual return is not a
    prediction of and does not represent the Fund's projected or actual
    performance.
 
(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) The Fund will deduct and retain a 2% redemption fee from the proceeds of all
    redemptions of Class A shares acquired as a result of the reorganization of
    G.T. Global Developing Markets Fund, Inc. into the Fund. The redemption fee
    will be imposed on all such redemptions before May 1, 1998. See "How to
    Redeem Shares."
 
(4) Expenses are estimated based on the fees and expenses the Fund is expected
    to incur during its initial fiscal year as an open-end fund and the
    Manager's and GT Global's undertaking to limit the Fund's expenses
    (exclusive of brokerage commissions, taxes, interest and extraordinary
    expenses) to the annual rate of 2.00% and 2.50% of the average daily net
    assets of the Fund's Class A shares and Class B shares, respectively.
    Without waivers, "Other expenses" and "Total Fund Operating Expenses" are
    estimated to be 0.65% and 2.13%, respectively, for Class A shares and 0.65%
    and 2.63%, respectively, for Class B shares. "Other expenses" include
    custody, transfer agent, legal and audit fees and other operating expenses.
    See "Management" herein and in the Statement of Additional Information for
    more information. 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."
 
(5) Reflects maximum level of fees authorized for each Class under the Fund's
    Rule 12b-1 distribution plans. The actual level of fees may be lower.
 
(6) Assumes payment of maximum sales charge by the investor.
 
(7) Assumes deduction of the applicable contingent deferred sales charge.

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

                             INVESTMENT OBJECTIVES
                                  AND POLICIES
 
- --------------------------------------------------------------------------------
 
The Fund's primary investment objective is long-term capital appreciation; its
secondary objective is income, to the extent consistent with seeking capital
appreciation. The Fund normally invests substantially all of its assets in
issuers in the developing (or "emerging") markets of Asia, Europe, Latin America
and elsewhere. A majority of the Fund's assets normally are invested in emerging
market equity securities. The Fund may invest in the following types of equity
securities: common stock, preferred stock, securities convertible into common
stock, American Depository Receipts, Global Depository Receipts, rights and
warrants to acquire such securities and substantially similar forms of equity
with comparable risk characteristics. The Fund may also invest in emerging
market debt securities that will be selected based on their potential to provide
a combination of capital appreciation and current income.
 
For purposes of the Fund's operations, emerging markets consist of all countries
determined by the Manager to have developing or emerging economies and markets.
These countries generally include every country in the world except the United
States, Canada, Japan, Australia, New Zealand and most countries located in
Western Europe. See "Investment Objectives and Policies" in the Statement of
Additional Information for a complete list of all the countries that the Fund
does not currently consider to be emerging markets.
 
For purposes of the Fund's policy of normally investing substantially all of its
assets in issuers in emerging markets, the Fund will consider investment in the
following emerging markets:
 
<TABLE>

  Algeria         Hong Kong      Peru

  Bolivia         India          Poland
  Botswana        Indonesia      Portugal

  El Salvador     Oman           Uruguay
  Finland         Pakistan       Venezuela
  Ghana           Panama         Zambia
  Greece          Paraguay       Zimbabwe
</TABLE>
 
Although the Fund considers each of the above-listed countries eligible for
investment, it will not be invested in all such markets at all times. Moreover,
investing in some of those markets currently may not be desirable or feasible,
due to the lack of adequate custody arrangements for the Fund's assets, overly
burdensome repatriation and similar restrictions, the lack of organized and
liquid securities markets, unacceptable political risks or for other reasons.
 
As used in this Prospectus, an issuer in an emerging market is an entity (1) for
which the principal securities trading market is an emerging market, as defined
above, (2) that (alone or on a consolidated basis) derives 50% or more of its
total revenues from business in emerging markets, provided that, in the
Manager's view, the value of such issuer's securities will tend to reflect
emerging market developments to a greater extent than developments elsewhere, or
(3) organized under the laws of, or with a principal office in, an emerging
market.
 
In selecting investments, the Manager seeks to identify those countries and
industries where economic and political factors, including currency movements,
are likely to produce above-average growth
 
                               Prospectus Page 8
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
rates over the long term. The Manager seeks those emerging markets that have
strongly developing economies and in which the markets are becoming more
sophisticated. The Manager then invests in those companies in such countries and
industries that it believes are best positioned and managed to take advantage of
these economic and political factors. The Manager believes that the issuers of
securities in emerging markets often have sales and earnings growth rates that
exceed those in developed countries and that such growth rates may in turn be
reflected in more rapid share price appreciation.
 
As opportunities to invest in securities in other emerging markets develop, the
Fund expects to expand and further broaden the group of emerging markets in
which it invests. In some cases, investments in debt securities could provide
the Fund with access to emerging markets in the early stages of their economic
development, when equity securities are not yet generally available or, in the
Manager's view, do not yet present an acceptable investment alternative. While
the Fund generally is not restricted in the portion of its assets that may be
invested in a single region, under normal conditions its assets will be invested
in issuers in at least four countries, and it will not invest more than 25% of
its assets in issuers in one country. The Fund's holdings of any one foreign
currency together with securities denominated in or indexed to such currency
will not exceed 40% of its assets.
 
INVESTMENTS IN DEBT SECURITIES. The Fund may invest up to 50% of its total
assets in the following types of emerging market debt securities: (1) debt
securities issued or guaranteed by governments, their agencies,
instrumentalities or political subdivisions, or by government owned, controlled
or sponsored entities, including central banks (collectively, "Sovereign Debt"),
including Brady Bonds; (2) interests in issuers organized and operated for the
purpose of restructuring the investment characteristics of Sovereign Debt; (3)
debt securities issued by banks and other business entities; and (4) debt
securities denominated in or indexed to the currencies of emerging markets. Debt
securities held by the Fund may take the form of bonds, notes, bills,
debentures, bank debt obligations, short-term paper, loan participations,
assignments and interests issued by entities organized and operated for the
purpose of restructuring the investment characteristics of any of the foregoing.
There is no requirement with respect to the maturity or duration of debt
securities in which the Fund may invest.
 
There is no limitation on the percentage of the Fund's assets that may be
invested in debt securities that are rated below investment grade. Investment in
below investment grade debt securities involves a high degree of risk and can be
speculative. These debt securities are the equivalent of high yield, high risk
bonds, commonly known as "junk bonds." Debt securities in which the Fund will
invest may not be rated; if rated, it is expected that such ratings will be
below investment grade. See "Risk Factors -- Risks Associated with Debt
Securities" and "-- Risks Associated with Below Investment Grade Debt
Securities."
 
The Fund may invest in "Brady Bonds," which are debt restructurings that provide
for the exchange of cash and loans for newly issued bonds. Brady Bonds have been
issued by the countries of Albania, Argentina, Brazil, Bulgaria, Costa Rica,
Dominican Republic, Ecuador, Ivory Coast, Jordan, Mexico, Nigeria, Panama, Peru,
Philippines, Poland, Uruguay, Venezuela and Vietnam, and are expected to be
issued by other emerging market countries. As of the date of this Prospectus,
the Fund is not aware of the occurrence of any payment defaults on Brady Bonds.
Investors should recognize, however, that Brady Bonds do not have a long payment
history. In addition, Brady Bonds are often rated below investment grade.
 
The Fund may invest in either collateralized or uncollateralized Brady Bonds.
U.S. dollar-denominated collateralized Brady Bonds, which may be fixed rate par
bonds or floating rate discount bonds, are collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Interest payments on such bonds generally are collateralized by cash or
securities in an amount that, in the case of fixed rate bonds, is equal to at
least one year of rolling interest payments or, in the case of floating rate
bonds, initially is equal to at least one year's rolling interest payments based
on the applicable interest rate at the time of issuance and is adjusted at
regular intervals thereafter.
 
Capital appreciation in debt securities may arise as a result of a favorable
change in relative foreign exchange rates, relative interest rate levels and/or
the creditworthiness of issuers.
 
ADDITIONAL INVESTMENT POLICIES
 
TEMPORARY DEFENSIVE STRATEGIES. In the interest of preserving shareholders'
capital, the Manager may employ a temporary defensive investment strategy for
the Fund if it determines such a strategy
 
                               Prospectus Page 9
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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 objectives. 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 AND REVERSE REPURCHASE AGREEMENTS. In connection with meeting requests
for the redemption of Fund shares, the Fund may borrow from banks or may borrow
through reverse repurchase agreements. The Fund also may borrow up to 5% of its
total assets for temporary or emergency purposes other than to meet redemptions,
but total borrowings may not exceed 33 1/3% of its total assets. However, the
Fund will not purchase securities while borrowings in excess of 5% of its total
assets are outstanding. Any borrowing by the Fund may cause greater fluctuation
in the value of its shares than would be the case if it did not borrow.
 
A reverse repurchase agreement is a borrowing transaction in which the Fund
transfers possession of a security to another party, such as a bank or
broker/dealer, in return for cash and agrees to repurchase the security in the
future at an agreed-upon price that includes an interest component.
 
SECURITIES LENDING. The Fund may lend its portfolio securities to broker/dealers
or to other institutional investors. Securities lending allows the Fund to
retain ownership of the securities loaned and, at the same time, enhances the
Fund's total return. The Fund limits its loans of portfolio securities to an
aggregate of 30% of the value of its total assets, measured at the time any such
loan is made. While a loan is outstanding, the borrower must maintain with the
Fund's custodian collateral consisting of cash, U.S. government securities or
certain irrevocable letters of credit equal to at least 100% of the value of the
borrowed securities plus any accrued interest or such other collateral as
permitted by the Fund's investment program and regulatory agencies, and as
approved by the Board. The risks in lending portfolio securities, as with other
extensions of secured credit, consist of possible delays in receiving additional
collateral or in recovery of the securities and possible loss of rights in the
collateral if the borrower fails financially.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. To attempt to increase
return, the Fund may write call options on securities. This strategy will be
employed only when, in the opinion of the Manager, the size of the premium the
Fund receives for writing the option is adequate to compensate it against the
risk that appreciation in the underlying security may not be fully realized if
the option is exercised. The Fund also is authorized to write put options to
attempt to enhance return, although it does not currently intend to do so.
 
The Fund may also use forward currency contracts, futures contracts, options on
securities, options on currencies, options on indices and options on futures
contracts to attempt to hedge against the overall level of investment and
currency risk normally associated with its investments. These instruments are
often referred to as "derivatives," which may be defined as financial
instruments whose performance is derived, at least in part, from the performance
of another asset (such as a security, currency or an index of securities). The
Fund may enter into such instruments up to the full value of its portfolio
assets. See "Options, Futures and Currency Strategies" in the Statement of
Additional Information.
 
To attempt to hedge against adverse movements in exchange rates between
currencies, the Fund may enter into forward currency contracts for the purchase
or sale of a specified currency at a specified future date. Such contracts may
involve the purchase or sale of a foreign currency against the U.S. dollar or
may involve two foreign currencies. The Fund may enter into forward currency
contracts either with respect to specific transactions or with respect to its
portfolio positions. The Fund also may purchase and sell put and call options on
currencies, futures contracts on currencies and options on such futures
contracts to hedge its portfolio against movements in exchange rates.
 
Only a limited market, if any, currently exists for options and futures
transactions relating to currencies of most emerging markets, to securities
denominated in such currencies or to securities of issuers domiciled or
principally engaged in business in such emerging markets. To the extent that
 
                               Prospectus Page 10
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
such a market does not exist, the Manager may not be able to effectively hedge
its investment in such markets.
 
In addition, the Fund may purchase and sell put and call options on equity and
debt securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or that the 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.
 
Further, the Fund may sell index futures contracts and may purchase put options
or write call options on such futures contracts to protect against a general
market or a specific market sector decline that could adversely affect the
Fund's portfolio. The Fund also may purchase index futures contracts and
purchase call options or write put options on such contracts to hedge against a
general market or market sector advance and thereby attempt to lessen the cost
of future securities acquisitions. Similarly, the Fund may use interest rate
futures contracts and options thereon to hedge the debt portion of its portfolio
against changes in the general level of interest rates.
 
INVESTMENT IN OTHER INVESTMENT COMPANIES OR VEHICLES. The Fund may be able to
invest in certain countries solely or primarily through governmentally
authorized investment vehicles or companies, some of which may be investment
vehicles or companies that are advised by the Manager or its affiliates
("Affiliated Funds"). Pursuant to the Investment Company Act of 1940, as amended
(the "1940 Act"), the Fund generally may invest up to 10% of its total assets in
the aggregate in shares of other investment companies and up to 5% of its total
assets in any one investment company, as long as each investment does not
represent more than 3% of the outstanding voting stock of the acquired
investment company at the time of investment.
 
Investment in other investment companies may involve the payment of substantial
premiums above the value of their portfolio securities and multiple layering of
fees and expenses and is subject to limitations under the 1940 Act and market
availability. The Fund does not intend to invest in other investment companies
unless, in the judgment of the Manager, the potential benefits of such
investment justify the payment of any applicable premium or sales charge. As a
shareholder in another investment company, the Fund would bear its ratable share
of that company's expenses, including its advisory and administration fees. At
the same time the Fund would continue to pay its own management fees and other
expenses. The Manager waives its advisory fee to the extent that the Fund
invests in an Affiliated Fund.
 
PRIVATIZATIONS. The governments in some emerging markets have been engaged in
programs of selling part or all of their stakes in government owned or
controlled enterprises ("privatizations"). The Manager believes that
privatizations may offer opportunities for significant capital appreciation and
intends to invest assets of the Fund in privatizations in appropriate
circumstances. In certain emerging markets, the ability of foreign entities such
as the Fund to participate in privatizations may be limited by local law or the
terms on which the Fund may be permitted to participate may be less advantageous
than those afforded local investors. There can be no assurance that governments
in emerging markets will continue to sell companies currently owned or
controlled by them or that privatization programs will be successful.
 
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Fund may purchase debt
securities on a "when-issued" basis and may purchase or sell such securities on
a "forward commitment" basis in order to hedge against anticipated changes in
interest rates and prices. The price, which is generally expressed in yield
terms, is fixed at the time the commitment is made, but delivery and payment for
the securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Fund will purchase
or sell when-issued securities and forward commitments only with the intention
of actually receiving or delivering the securities, as the case may be. No
income accrues on securities that have been purchased pursuant to a forward
commitment or on a when-issued basis prior to delivery to the Fund. If the Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment, it
may incur a gain or loss. At the time the Fund enters into a transaction on a
when-issued or forward commitment basis, a segregated account consisting of cash
or liquid securities equal to the value of the when-issued or forward commitment
securities will be established and maintained with the Fund's custodian bank and
will be marked to market daily. There is a risk that the securities may not be
delivered and that the Fund may incur a loss.
 
                               Prospectus Page 11
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Fund may invest in fixed and floating
rate loans ("Loans") arranged through private negotiations between a foreign
entity and one or more financial institutions ("Lenders"). The majority of the
Fund's investments in Loans in emerging markets is expected to be in the form of
participations in Loans ("Participations") and assignments of portions of Loans
from third parties ("Assignments"). Participations typically will result in the
Fund having a contractual relationship only with the Lender, not with the
borrower. The Fund will have the right to receive payments of principal,
interest and any fees to which it is entitled only from the Lender selling the
Participation and only upon receipt by the Lender of the payments from the
borrower. In connection with purchasing Participations, the Fund generally will
have no right to enforce compliance by the borrower with the terms of the loan
agreement relating to the loan, nor any rights of set-off against the borrower,
and the Fund may not directly benefit from any collateral supporting the Loan in
which it has purchased the Participation. As a result, the Fund will assume the
credit risk of both the borrower and the Lender that is selling the
Participation.
 
In the event of the insolvency of the Lender selling a Participation, the Fund
may be treated as a general creditor of the Lender and may not benefit from any
set-off between the Lender and the borrower. The Fund will acquire
Participations only if the Lender interpositioned between the Fund and the
borrower is determined by the Manager to be creditworthy. When the Fund
purchases Assignments from Lenders, the Fund will acquire direct rights against
the borrower on the Loan. However, because Assignments are arranged through
private negotiations between potential assignees and assignors, the rights and
obligations acquired by the Fund as the purchaser of an Assignment may differ
from, and be more limited than, those held by the assigning Lender.
 
ZERO COUPON SECURITIES. The Fund may invest in certain zero coupon securities
that are "stripped" U.S. Treasury notes and bonds. The Fund also may invest in
zero coupon and other deep discount securities issued by foreign governments and
domestic and foreign corporations, including certain Brady Bonds and other
foreign debt, and in payment-in-kind securities. Zero coupon securities pay no
interest to holders prior to maturity, and payment-in-kind securities pay
"interest" in the form of additional securities. However, a portion of the
original issue discount on zero coupon securities and the interest on
payment-in-kind securities will be included in the Fund's income. Accordingly,
for the Fund to continue to qualify for tax treatment as a regulated investment
company and to avoid a certain excise tax (see "Taxes" in the Statement of
Additional Information), it may be required to distribute an amount that is
greater than the total amount of cash it actually receives. These distributions
may be made from the Fund's cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund will not be able to purchase additional
income-producing securities with cash used to make such distributions, and its
current income ultimately may be reduced as a result. Zero coupon and
payment-in-kind securities usually trade at a deep discount from their face or
par value and will be subject to greater fluctuations of market value in
response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
 
INDEXED COMMERCIAL PAPER. The Fund may invest without limitation in commercial
paper that is indexed to certain specific foreign currency exchange rates. The
terms of such commercial paper provide that its principal amount is adjusted
upwards or downwards (but not below zero) at maturity to reflect changes in the
exchange rate between two currencies while the obligation is outstanding. The
Fund will purchase such commercial paper with the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency, but the amount of principal payable by the issuer at
maturity will change in proportion to the change (if any) in the exchange rate
between the two specified currencies between the date the instrument is issued
and the date the instrument matures. While such commercial paper entails the
risk of loss of principal, the potential for realizing gains as a result of
changes in foreign currency exchange rates enables the Fund to hedge against a
decline in the U.S. dollar value of investments denominated in foreign
currencies while seeking to provide an attractive money market rate of return.
The Fund will not purchase such commercial paper for speculation.
 
OTHER INDEXED SECURITIES. The Fund may invest in certain other indexed
securities, which are securities whose prices are indexed to the prices of other
securities, securities indices, currencies, precious metals or other commodities
or other financial indicators. Indexed securities typically, but
 
                               Prospectus Page 12
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
not always, are debt securities or deposits whose value at maturity or coupon
rate is determined by reference to a specific instrument or statistic. The
performance of indexed securities depends to a great extent on the performance
of the security, currency or other instrument to which they are indexed and also
may be influenced by interest rate changes in the United States and abroad. At
the same time, indexed securities are subject to the credit risks associated
with the issuer of the security, and their values may decline substantially if
the issuer's creditworthiness deteriorates. Indexed securities may be more
volatile than the underlying instruments. New forms of indexed securities
continue to be developed. The Fund may invest in such securities to the extent
consistent with its investment objectives.
 
OTHER INFORMATION. The Fund's investment objectives may not be changed without
the approval of a majority of its outstanding voting securities. A "majority of
its outstanding voting securities" means the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented, or (ii) more than 50% of the outstanding shares. In addition, the
Fund has adopted certain investment limitations that also may not be changed
without shareholder approval. A complete description of these limitations is
included in the Statement of Additional Information. Unless specifically noted,
the Fund's investment policies described in this Prospectus and in the Statement
of Additional Information may be changed by the 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.

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

and political issues, and some of them have experienced high rates of inflation
in recent years and have extensive internal debt. Among other effects, high
inflation and internal debt service requirements may adversely affect the cost
and availability of future domestic sovereign borrowing to finance governmental
programs and may have other adverse social, political and economic consequences.
Political changes or a deterioration of a country's domestic economy or balance
of trade may affect its willingness to service its sovereign debt. Although the
Manager intends to manage the Fund in a manner that will minimize the exposure
to such risks, there can be no assurance that adverse political changes will not
cause the Fund to suffer a loss of interest or principal on any of its holdings.
 
In recent years, some of the emerging market countries in which the Fund expects
to invest have encountered difficulties in servicing their sovereign debt
obligations. Some of these countries have withheld payments of interest and/or
principal of sovereign debt. These difficulties have also led to agreements to
restructure external debt obligations -- in particular, commercial bank loans --
typically by rescheduling principal payments, reducing interest rates and
extending new credits to finance interest payments on existing debt. In the
future, holders of emerging market sovereign debt securities may be requested to
participate in similar rescheduling of such debt. Certain emerging market
countries are among the largest debtors to commercial banks and foreign
governments. Currently, Brazil, Mexico and Argentina are the largest debtors
among developing countries. At times certain emerging market countries have
declared moratoria on the payment of principal and interest on external debt;
such a moratorium is currently in effect in certain emerging market countries.
There is no bankruptcy proceeding by which a creditor may collect in whole or in
part sovereign debt on which an emerging market government has defaulted.
 
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
 
As noted above, sovereign debt obligations issued by emerging market governments
generally are deemed to be the equivalent in terms of quality to securities
rated below investment grade by Moody's and S&P. Such securities are regarded as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligations and involve
major risk exposure to adverse conditions. Some of such securities, with respect
to which the issuer currently may not be paying interest or may be in payment
default, may be comparable to securities rated D by S&P or C by Moody's. The
Fund may have difficulty disposing of and valuing certain sovereign debt
obligations because there may be a limited trading market for such securities.
Because there is no liquid secondary market for many of these securities, the
Fund anticipates that such securities could be sold only to a limited number of
dealers or institutional investors.

                                 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 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 by such investors 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 DEVELOPING MARKETS 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.

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") plus a sales charge

- ------------------
*   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) 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 Code Section 401(k) plans, 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).

value without imposition of sales charges when investments are made by the
following classes of investors:

which are sponsored by organizations that have at least 100 but less than 1,000
employees, and trustees or other fiduciaries purchasing shares for employee
benefit plans which are sponsored by organizations with collective retirement
plan assets of $500,000 or more and have less than 100 employees, and purchases

shares with a broker/dealer that has entered into a dealer agreement with GT
Global) and the children, siblings and parents of such employees.
 
(iv) Companies exchanging shares with or selling assets to one or more of the GT
Global Mutual Funds pursuant to a merger, acquisition or exchange offer.
 
(v) Shareholders of any of the GT Global Mutual Funds as of April 30, 1987 who
since that date continually have owned shares of one or more of the GT Global

the proceeds of which are reinvested in Fund shares.
 
(xi) Accounts for which a Financial Institution charges an account management
fee, provided the Financial Institution has entered into an agreement with GT
Global regarding such accounts.
 
(xii) Certain former AMA Investment Advisers' shareholders who became
shareholders of the GT Global Health Care Fund in October 1989, and 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-
 
                               Prospectus Page 21
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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 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
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.
 
Investors should be aware that the Fund may, in the future, suspend the offering
of its shares although not for previously established LOIs. If all ongoing sales
of the Fund shares are suspended, however, an LOI executed in connection with
the offering of the Fund's shares may continue to be completed by the purchase
of shares of one or more other GT Global Mutual Funds (other than GT Global
Dollar Fund).
 
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
 
                               Prospectus Page 22
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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 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 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

<PAGE>
                       GT GLOBAL DEVELOPING MARKETS 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

            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 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
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.
 
                               Prospectus Page 24
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
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 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 Exchange(s)." If shares of
the GT Global Mutual Funds 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. Until May 1, 1998, the Fund will deduct a 2% fee from the amount of
all exchanges of Class A shares of the Fund acquired as a result of the
reorganization of the Predecessor Fund into the Fund. See "How to Redeem Shares
- -- Redemption Fee." 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." 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 DOLLAR FUND
   -- GT GLOBAL EMERGING MARKETS FUND
   -- GT GLOBAL EUROPE GROWTH FUND
   -- GT GLOBAL FINANCIAL SERVICES FUND
   -- GT GLOBAL GOVERNMENT INCOME FUND
   -- GT GLOBAL GROWTH & INCOME FUND
   -- GT GLOBAL HEALTH CARE FUND
   -- GT GLOBAL HIGH INCOME FUND
   -- GT GLOBAL INFRASTRUCTURE FUND
   -- GT GLOBAL INTERNATIONAL 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 information 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. Shareholders who hold certificates for shares may
not redeem by telephone. REDEMPTION REQUESTS MAY NOT BE MADE BY TELEPHONE FOR
FIFTEEN DAYS

<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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 in the Fund 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.
 
REDEMPTION FEE. Until May 1, 1998, the Fund will deduct a 2% fee from the
proceeds of all redemptions of Class A shares of the Fund acquired as a result
of the reorganization of the Predecessor Fund into the Fund. The redemption fee
will be paid to the Fund and not to GT Global or the Manager, and is intended to
offset brokerage and other costs the Fund may experience as a result of such
redemptions.
 
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 DEVELOPING MARKETS 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
dividends and 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. Net asset value is determined separately for each
class of the Fund's shares.
 
Equity securities are valued at the last sale price on the exchange or in the
over-the-counter market in which the 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 the 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 will
result in different net asset values. The per share net asset value of the Class
B shares generally will be lower than that of the Class A shares 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 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 Class A and Class B
shares 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 between the classes.

                         DIVIDENDS, OTHER DISTRIBUTIONS
                          AND FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. The Fund annually declares and pays as a
dividend all of 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 capital gains and net gains from foreign
currency transactions, if any. The Fund may make an additional dividend or other
distribution each year 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

                       GT GLOBAL DEVELOPING MARKETS FUND
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 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 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 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 its average daily net assets, at the
annualized rate of .975% on the first $500 million, .95% on the next $500
million, .925% on the next $500 million and .90% on amounts thereafter. 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
2.00% and 2.50% of the average daily net assets of the Fund's Class A and Class
B shares, respectively. These undertakings 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 the 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 the 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. Brokerage transactions may be executed through
affiliates of Liechtenstein Global Trust. High portfolio turnover (over 100%)
involves correspondingly greater brokerage commissions and other transaction
costs that the Fund will bear directly and could result in the realization of
net capital gains which would be taxable when distributed to shareholders.

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 on 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.
 
The Fund reserves the right to suspend the offering of its shares upon the
advice of the Manager that doing so is in the best interests of the portfolio
management process.
 
GT Global, at its own expense, may provide additional promotional incentives to
brokers that sell shares of the Fund and/or shares of the other GT Global Mutual
Funds. In some instances additional compensation or promotional incentives may
be offered to broker/dealers that have sold or may sell significant amounts of
shares during specified periods of time. Such compensation and incentives may
include, but are not limited to, cash, merchandise, trips and financial
assistance to broker/dealers in connection with preapproved conferences or
seminars, sales or training programs for invited sales personnel, payment for
travel expenses (including meals and lodging) incurred by sales personnel and
members of their families or other invited guests to various locations for such
seminars or training programs, seminars for the public, advertising and sales
campaigns regarding one or more of the GT Global Mutual Funds, and/ or other
events sponsored by the broker/dealers. In addition, 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 0.50% 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 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.
 
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. GT Global expects that it will continue to
incur certain of such service and distribution expenses, including trail
commission payments and other account servicing costs, during any suspension of
the offering of the Fund's Shares.
 
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 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,
27th Floor, San Francisco, CA 94111.
 
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
 
                               Prospectus Page 36

                       GT GLOBAL DEVELOPING MARKETS FUND
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.

                       GT GLOBAL DEVELOPING MARKETS FUND
 
                           INVESTMENT OBJECTIVES AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES
The  primary investment objective of the Fund is long-term capital appreciation.
Its secondary  investment objective  is income,  to the  extent consistent  with
seeking capital appreciation. The Fund normally invests substantially all of its
assets  in issuers  in the developing  (or "emerging") markets  of Asia, Europe,
Latin America and elsewhere. The Fund does not consider the following  countries
to  be emerging markets: Australia,  Austria, Belgium, Canada, Denmark, England,
Finland, France, Germany, Ireland, Italy,  Japan, the Netherlands, New  Zealand,
Norway,  Spain, Sweden, Switzerland and the  United States. In determining which
countries constitute emerging  markets, the Manager  will consider, among  other
things,   data,  analysis,   and  classification   of  countries   published  or
disseminated by  the  International  Bank  for  Reconstruction  and  Development
(commonly  known as  the World Bank)  and the  International Finance Corporation
("IFC").
 
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.
 
In  determining  the  appropriate  distribution  of  investments  among  various
countries and geographic regions for the Fund, the Manager ordinarily  considers
the  following  factors:  prospects  for  relative  economic  growth  among  the
different countries in which the Fund may invest; expected levels of  inflation;
government  policies influencing  business conditions; the  outlook for currency
relationships;  and  the  range  of  the  individual  investment   opportunities
available to international investors.
 
In  analyzing  companies in  emerging markets  for investment  by the  Fund, the
Manager ordinarily looks for  one or more of  the following characteristics:  an
above-average  earnings  growth  per  share; high  return  on  invested capital;
healthy balance  sheet;  sound financial  and  accounting policies  and  overall
financial  strength;  strong  competitive  advantages;  effective  research  and
product development  and  marketing;  efficient  service;  pricing  flexibility;
strength  of management; and general operating characteristics which will enable
the companies  to  compete successfully  in  their respective  marketplaces.  In
certain countries, governmental restrictions and other limitations on investment
may  affect the maximum percentage of equity ownership in any one company by the
Fund. In addition, in some instances  only special classes of securities may  be
purchased by foreigners and the market prices, liquidity and rights with respect
to those securities may vary from shares owned by nationals.
 
Although  the 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.
 
The Fund may be prohibited under the Investment Company Act of 1940, as  amended
("1940 Act"), from purchasing the securities of any foreign company that, in its
most  recent  fiscal year,  derived more  than  15% of  its gross  revenues from
securities-related activities ("securities-related companies").  In a number  of
countries,   commercial  banks  act  as  securities  broker/dealers,  investment
advisers and underwriters or otherwise engage in securities-related  activities,
which  may limit the Fund's ability to hold securities issued by such banks. The
Fund has  obtained an  exemption  from the  Securities and  Exchange  Commission
("SEC") to permit it to invest in certain of these securities subject to certain
restrictions.
 
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  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
    
 
                   Statement of Additional Information Page 2
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
   
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 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. Warrants are securities  permitting,
but   not  obligating,  their  holder  to  subscribe  for  other  securities  or
commodities. Warrants do not  carry with them the  right to dividends or  voting
rights  with  respect  to  the  securities that  they  entitle  their  holder to
purchase, and they do not represent any rights in the assets of the issuer. As a
result, warrants may be considered more speculative than certain other types  of
investments.  In addition,  the value of  a warrant does  not necessarily change
with the value of the underlying securities  and a warrant ceases to have  value
if it is not exercised prior to its expiration date.
 
LENDING OF PORTFOLIO SECURITIES
For  the purpose of realizing additional income, the 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
 
                   Statement of Additional Information Page 3
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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 15% of the value of  its net assets would be invested in  such
repurchase agreements and other illiquid investments.
 
BORROWING AND REVERSE REPURCHASE AGREEMENTS
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.
 
                   Statement of Additional Information Page 4
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
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 will  maintain, in a segregated
account with a custodian, cash or  liquid securities in an amount sufficient  to
cover  its obligations under 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.
 
YANKEE BONDS
The  Fund may invest in U.S. dollar-denominated  bonds sold in the United States
by non-U.S.  issuers ("Yankee  bonds"). As  compared with  bonds issued  in  the
United  States, such bond issues  normally carry a higher  interest rate but are
less actively traded.
 
TEMPORARY DEFENSIVE STRATEGIES
The Fund may invest  in the following types  of money market instruments  (i.e.,
debt  instruments with less than 12 months remaining until maturity) denominated
in U.S. dollars or other currencies: (a) obligations issued or guaranteed by the
U.S.   or   foreign   governments,   their   agencies,   instrumentalities    or
municipalities;  (b)  obligations  of  international  organizations  designed or
supported  by  multiple  foreign  governmental  entities  to  promote   economic
reconstruction  or  development;  (c)  finance  company  obligations,  corporate
commercial  paper  and  other   short-term  commercial  obligations;  (d)   bank
obligations  (including certificates of deposit,  time deposits, demand deposits
and bankers'  acceptances);  (e)  repurchase  agreements  with  respect  to  the
foregoing;  and (f) other substantially  similar short-term debt securities with
comparable characteristics.
 
   
The Fund  may invest  in commercial  paper rated  as low  as A-3  by Standard  &
Poor's,  a division of The McGraw-Hill Companies, Inc. ("S&P") or P-3 by Moody's
Investors Service, Inc. ("Moody's") or, if not rated, determined by the  Manager
to be of comparable quality. Obligations rated A-3 and P-3 are considered by S&P
and  Moody's, respectively, to have an acceptable capacity for timely repayment.
However, these securities may be more  vulnerable to adverse effects of  changes
in circumstances than obligations carrying higher designations.
    
 
PREMIUM SECURITIES
The  Fund  may invest  in  income securities  bearing  coupon rates  higher than
prevailing market rates.  Such "premium" securities  are typically purchased  at
prices greater than the principal amounts payable on maturity. The Fund will not
 
                   Statement of Additional Information Page 5
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
amortize  the premium paid for such securities in calculating its net investment
income. As a result, in such cases the purchase of such securities provides  the
Fund  a higher  level of  investment income  distributable to  shareholders on a
current basis than if the Fund purchased securities bearing current market rates
of interest. If securities purchased by the Fund at a premium are called or sold
prior to maturity, the Fund will realize a  loss to the extent the call or  sale
price  is less than  the purchase price.  Additionally, the Fund  will realize a
loss if it holds such securities to maturity.
 
INDEXED DEBT SECURITIES
The Fund  may invest  in debt  securities  issued by  banks and  other  business
entities  not located in developing market countries that are indexed to certain
specific foreign  currency exchange  rates, interest  rates or  other  reference
rates.  The  terms of  such securities  provide that  their principal  amount is
adjusted upwards or  downwards (but ordinarily  not below zero)  at maturity  to
reflect  changes in  the exchange rate  between two currencies  (or other rates)
while the obligations are outstanding. While such securities offer the potential
for an  attractive  rate  of return,  they  also  entail the  risk  of  loss  of
principal.  New forms of such securities continue  to be developed. The Fund may
invest  in  such  securities  to  the  extent  consistent  with  its  investment
objectives.
 
STRUCTURED INVESTMENTS
The  Fund may invest a portion of  its assets in interests in entities organized
and  operated  solely   for  the   purpose  of   restructuring  the   investment
characteristics  of  Sovereign Debt.  This  type of  restructuring  involves the
deposit with  or purchase  by an  entity, such  as a  corporation or  trust,  of
specified  instruments (such  as commercial bank  loans or Brady  Bonds) and the
issuance by  that entity  of  one or  more  classes of  securities  ("Structured
Investments")   backed  by,   or  representing  interests   in,  the  underlying
instruments. The  cash flow  on the  underlying instruments  may be  apportioned
among  the  newly  issued  Structured  Investments  to  create  securities  with
different  investment  characteristics  such  as  varying  maturities,   payment
priorities  and interest  rate provisions, and  the extent of  the payments made
with respect to Structured  Investments is dependent on  the extent of the  cash
flow  on the underlying instruments. Because  Structured Investments of the type
in which  the  Fund anticipates  it  will  invest typically  involve  no  credit
enhancement,  their  credit risk  generally will  be equivalent  to that  of the
underlying instruments.
 
The Fund is permitted  to invest in  a class of  Structured Investments that  is
either  subordinated  or not  subordinated to  the right  of payment  of another
class. Subordinated  Structured Investments  typically  have higher  yields  and
present greater risks than unsubordinated Structured Investments.
 
Certain  issuers  of  Structured Investments  may  be deemed  to  be "investment
companies" as defined in  the 1940 Act.  As a result,  the Fund's investment  in
these Structured Investments may be limited by the restrictions contained in the
1940   Act  described  above  under   "Investment  Objectives  and  Policies  --
Investments in Other Investment Companies." Structured Investments are typically
sold in private placement transactions, and there currently is no active trading
market for Structured Investments.
 
STRIPPED INCOME SECURITIES
Stripped income securities are obligations representing an interest in all or  a
portion  of  the income  or  principal components  of  an underlying  or related
security, a pool of securities  or other assets. In  the most extreme case,  one
class  will receive all of the interest (the interest only or "IO" class), while
the other class will  receive all of the  principal (the principal-only or  "PO"
class). The market values of stripped income securities tend to be more volatile
in   response  to  changes  in  interest  rates  than  are  conventional  income
securities.
 
FLOATING AND VARIABLE RATE INCOME SECURITIES
Income securities may provide for floating or variable rate interest or dividend
payments. The floating  or variable  rate may be  determined by  reference to  a
known  lending rate, such as a bank's  prime rate, a certificate of deposit rate
or the London Inter  Bank Offered Rate (LIBOR).  Alternatively, the rate may  be
determined  through  an auction  or remarketing  process. The  rate also  may be
indexed to  changes  in the  values  of  interest rate  or  securities  indexes,
currency  exchange rates or other commodities. The amount by which the rate paid
on an income security  may increase or  decrease may be  subject to periodic  or
lifetime  caps. Floating and variable  rate income securities include securities
whose rates  vary inversely  with  changes in  market  rates of  interest.  Such
securities  may also pay a rate of interest determined by applying a multiple to
the variable  rate.  The extent  of  increases and  decreases  in the  value  of
securities  whose rates vary inversely with  changes in market rates of interest
generally will  be larger  than comparable  changes  in the  value of  an  equal
principal  amount  of  a  fixed rate  security  having  similar  credit quality,
redemption provisions and maturity.
 
SWAPS, CAPS, FLOORS AND COLLARS
The Fund may enter into interest rate, currency and index swaps and may purchase
or sell related caps, floors and  collars and other derivative instruments.  The
Fund  expects to enter into these transactions primarily to preserve a return or
 
                   Statement of Additional Information Page 6
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
spread on  a particular  investment  or portion  of  its portfolio,  to  protect
against  currency  fluctuations, as  a  technique for  managing  the portfolio's
duration (I.E.,  the price  sensitivity  to changes  in  interest rates)  or  to
protect  against any  increase in the  price of securities  the Fund anticipates
purchasing at a later date. The Fund intends to use these transactions as hedges
and will not  sell interest  rate caps,  floors or collars  if it  does not  own
securities or other instruments providing an income stream roughly equivalent to
what the Fund may be obligated to pay.
 
Interest rate swaps involve the exchange by the Fund with another party of their
respective  commitments to pay or receive  interest (for example, an exchange of
floating rate  payments for  fixed rate  payments) with  respect to  a  notional
amount of principal. A currency swap is an agreement to exchange cash flows on a
notional amount based on changes in the values of the reference indices.
 
The  purchase of a cap entitles the  purchaser to receive payments on a notional
principal amount from the party selling the  cap to the extent that a  specified
index  exceeds a predetermined  interest rate. The purchase  of an interest rate
floor entitles the purchaser to receive payments on a notional principal  amount
from  the party  selling the floor  to the  extent that a  specified index falls
below a predetermined interest rate  or amount. A collar  is a combination of  a
cap  and a floor that preserves a certain return within a predetermined range of
interest rates or values.

                         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, the 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
 
                   Statement of Additional Information Page 7
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
    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  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 has  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 in order to protect against an  anticipated
decline  in the  value of  the security  or currency.  Such hedge  protection is
provided only during the life of the put option when the Fund, 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
 
                   Statement of Additional Information Page 9
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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.
 
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 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
 
                  Statement of Additional Information Page 10
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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  the 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 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, currency or stock index futures contracts
(collectively,  "Futures" or "Futures Contracts") as  a hedge against changes in
prevailing levels  of interest  rates, currency  exchange rates  or stock  price
levels, respectively, in order to establish more definitely the effective return
on  securities or currencies held  or intended to be  acquired by it. 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
 
                  Statement of Additional Information Page 11
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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
 
                  Statement of Additional Information Page 12
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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
 
                  Statement of Additional Information Page 13
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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. 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
 
                  Statement of Additional Information Page 14
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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  15% of  its  net assets  in  illiquid  securities.
Securities  may  be considered  illiquid if  the  Fund cannot  reasonably expect
within seven days to sell the security for approximately the amount at which the
Fund values such  securities. The sale  of illiquid securities,  if they can  be
sold  at all, generally  will require more  time and result  in higher brokerage
charges or dealer discounts and other  selling expenses than the sale of  liquid
securities, such as securities eligible for trading on U.S. securities exchanges
or in the over-the-counter markets. Moreover, restricted securities which may be
illiquid  for purposes  of this limitation,  often sell,  if at all,  at a price
lower than similar securities that are not subject to restrictions on resale.
 
Illiquid securities include those that are subject to restrictions contained  in
the  securities laws  of other  countries. However,  securities that  are freely
marketable in the country  where they are principally  traded, but would not  be
freely  marketable in the United States,  will not be considered illiquid. Where
registration is required, 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
 
                  Statement of Additional Information Page 15
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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
the Fund, however, could  affect adversely the  marketability of such  portfolio
securities  and the Fund might be unable  to dispose of such securities promptly
or at favorable prices.
 
With respect  to  liquidity determinations  generally,  the 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  in  accordance with
procedures approved by  the Board. The  Manager takes into  account a number  of
factors  in reaching liquidity decisions, including (i) the frequency of trading
in the security, (ii) the  number of dealers who  make quotes for the  security,
(iii)  the  number  of dealers  who  have undertaken  to  make a  market  in the
security, (iv) the number  of other potential purchasers  and (v) the nature  of
the  security and  how trading is  effected (e.g.,  the time needed  to sell the
security, how offers are solicited and  the mechanics of transfer). The  Manager
monitors  the liquidity of  securities in the  Fund's portfolio and periodically
reports on such decisions to the Board.
 
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.
 
In addition,  even though  opportunities for  investment may  exist in  emerging
markets,  any change in the  leadership or policies of  the governments of those
countries or  in  the leadership  or  policies  of any  other  government  which
exercises  a significant influence over those  countries, may halt the expansion
of or reverse the  liberalization of foreign  investment policies now  occurring
and thereby eliminate any investment opportunities which may currently exist.
 
Investors should note that upon the accession to power of authoritarian regimes,
the  governments of a number of Latin American countries previously expropriated
large quantities of  real and personal  property similar to  the property  which
will  be represented  by the  securities purchased  by the  Fund. The  claims of
property owners against those governments were never finally settled. There  can
be  no assurance  that any property  represented by securities  purchased by the
Fund will not also be  expropriated, nationalized, or otherwise confiscated.  If
such  confiscation were to occur,  the Fund could lose  its entire investment in
such countries. The Fund's investments would similarly be adversely affected  by
exchange control regulation in any of those countries.
 
    RELIGIOUS  AND ETHNIC  STABILITY. 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
 
                  Statement of Additional Information Page 16
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
specific  class of securities of a company that may have less advantageous terms
than securities of the  company available for  purchase by nationals.  Moreover,
the national policies of certain countries may restrict investment opportunities
in  issuers or industries  deemed sensitive to  national interests. In addition,
some countries require governmental approval for the repatriation of  investment
income,  capital or  the proceeds of  securities sales by  foreign investors. If
there is  a  deterioration in  a  country's balance  of  payments or  for  other
reasons,  a  country  may  impose restrictions  on  foreign  capital remittances
abroad. The 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 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  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 United
States, and other economic and financial conditions affecting the world economy.
 
Although the Fund values its assets daily in terms of U.S. dollars, it 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 United
States  and  foreign  securities  transactions  usually  are  subject  to  fixed
commissions,  which  generally are  higher than  negotiated commissions  on U.S.
transactions. In addition,  foreign securities  transactions may  be subject  to
difficulties  associated  with the  settlement of  such transactions.  Delays in
settlement could  result  in temporary  periods  when  assets of  the  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
 
                  Statement of Additional Information Page 17
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
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  securities of
foreign issuers may  be subject  to withholding  taxes by  the foreign  issuer's
country,  thereby reducing that  income or delaying the  receipt of income where
those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION. To the extent 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  EMERGING  MARKETS.  Investing  in  equity
securities  of  companies  in emerging  markets  may entail  greater  risks than
investing in equity securities in  developed countries. These risks include  (i)
less  social, political and  economic stability; (ii) the  small current size of
the markets for such securities and  the currently low or nonexistent volume  of
trading,  which result in a  lack of liquidity and  in greater price volatility;
(iii) certain  national  policies  which  may  restrict  the  Fund's  investment
opportunities,  including restrictions  on investment  in issuers  or industries
deemed sensitive  to national  interests;  (iv) foreign  taxation; and  (v)  the
absence  of  developed structures  governing  private or  foreign  investment or
allowing for judicial redress for injury to private property.
 
Investing in the securities of companies in emerging markets 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.
 
    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
U.S.  securities markets and should be considered highly speculative. Such risks
include the following: (1) delays in settling
 
                  Statement of Additional Information Page 18
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
portfolio transactions  and risk  of loss  arising out  of the  system of  share
registration  and  custody; (2)  the  risk that  it  may be  impossible  or more
difficult than in  other countries  to obtain  and/or enforce  a judgement;  (3)
pervasiveness  of  corruption and  crime in  the  economic system;  (4) currency
exchange rate volatility and the lack of available currency hedging instruments;
(5) higher rates of  inflation (including the risk  of social unrest  associated
with  periods of hyper-inflation) and high unemployment; (6) controls on foreign
investment and local practices disfavoring foreign investors and limitations  on
repatriation  of  invested capital,  profits and  dividends,  and on  the 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  United States. 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 United  States,
both  of  which  factors tend  to  result  in lower  discount  rates  and higher
price-earnings ratios in Japan than in the United States.
 
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.
 
Many of the Asia Pacific region countries may be subject to a greater degree  of
social,  political  and economic  instability  than is  the  case in  the United
States. Such instability may result from, among other things, the following: (i)
authoritarian governments  or military  involvement  in political  and  economic
decision  making, and changes in  government through extra-constitutional means;
(ii) popular unrest associated with demands for improved political, economic and
social conditions;  (iii) internal  insurgencies;  (iv) hostile  relations  with
neighboring  countries; and (v) ethnic,  religious and racial disaffection. Such
social, political  and  economic  instability could  significantly  disrupt  the
principal  financial markets in which the  Fund invests and adversely affect the
value of  the  Fund's  assets.  In  addition,  asset  expropriations  or  future
confiscatory levels of taxation possibly may affect the Fund.
 
Several  of the  Asia Pacific region  countries have,  or in the  past have had,
hostile relationships  with neighboring  nations  or have  experienced  internal
insurgency.  Thailand has experienced  border conflicts with  Laos and Cambodia,
and India is engaged in border disputes with several of its neighbors, including
China and Pakistan. An uneasy truce exists between North Korea and South  Korea,
and the recurrence of hostilities remains possible. Reunification of North Korea
and  South Korea could have a detrimental  effect on the economy of South Korea.
Also, China  continues  to  claim  sovereignty  over  Taiwan  and  recently  has
conducted military maneuvers near Taiwan.
 
                  Statement of Additional Information Page 19

                       GT GLOBAL DEVELOPING MARKETS FUND
 
The economies of most of the Asia Pacific region countries are heavily dependent
upon  international  trade  and  are accordingly  affected  by  protective trade
barriers and the economic conditions of their trading partners, principally  the
United  States, Japan,  China and the  European Community. The  enactment by the
United States  or  other  principal  trading  partners  of  protectionist  trade
legislation,  reduction of foreign investment in the local economies and general
declines in  the  international  securities markets  could  have  a  significant
adverse effect upon the securities markets of the Asia Pacific region countries.
In  addition,  the  economies of  some  of  the Asia  Pacific  region countries,
Australia and Indonesia, for example, are vulnerable to weakness in world prices
for their commodity exports, including crude oil.
 
China recently assumed sovereignty over Hong  Kong in July 1997. Although  China
has  committed by treaty to preserve the economic and social freedoms enjoyed in
Hong Kong for fifty years, the continuation of the current form of the  economic
system  in Hong Kong will  depend on the actions of  the government of China. In
addition, such assumption of sovereignty has increased sensitivity in Hong  Kong
to  political developments and  statements by public  figures in China. Business
confidence in  Hong  Kong, therefore,  can  be significantly  affected  by  such
developments  and  statements, which  in turn  can  affect markets  and business
performance.
 
In addition, the Chinese  sovereignty over Hong Kong  also presents a risk  that
the  Hong Kong dollar will  be devalued and a risk  of possible loss of investor
confidence in the Hong Kong markets and dollar. However, factors exist that  are
likely to mitigate this risk. First, China has stated its intention to implement
a  "one country, two systems" policy,  which would preserve monetary sovereignty
and leave control in the hands of the Hong Kong Monetary Authority ("HKMA").
 
Second, fixed  rate  parity  with  the  U.S.  dollar  is  seen  as  critical  to
maintaining  investors'  confidence  in  the transition  to  Chinese  rule, and,
therefore, it is anticipated that, if international investors lose confidence in
Hong Kong  dollar assets,  the HKMA  would intervene  to support  the  currency,
though  such  intervention cannot  be assured.  Third,  Hong Kong's  and China's
sizable combined foreign exchange  reserve may be used  to support the value  of
the Hong Kong dollar, provided that China does not appropriate such reserves for
other uses, which is not anticipated but cannot be assured. Finally, China would
be  likely to experience significant adverse political and economic consequences
if confidence  in the  Hong Kong  dollar and  the territory  assets were  to  be
endangered.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.
 
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.
 
    SOVEREIGN DEBT. Sovereign Debt generally offers high yields, reflecting  not
only  perceived  credit risk,  but also  the  need to  compete with  other local
investments in domestic financial markets. Certain Latin American countries  are
among  the  largest  debtors  to commercial  banks  and  foreign  governments. A
sovereign debtor's willingness or ability to repay principal and interest due in
a timely  manner  may  be  affected  by, among  other  factors,  its  cash  flow
situation,  the extent of  its foreign reserves,  the availability of sufficient
foreign exchange on the  date a payment  is due, the relative  size of the  debt
service  burden to the economy as a whole, the sovereign debtor's policy towards
the International  Monetary  Fund  and  the political  constraints  to  which  a
sovereign  debtor  may  be  subject.  Sovereign  debtors  may  default  on their
Sovereign  Debt.  Sovereign   debtors  may   also  be   dependent  on   expected
disbursements  from foreign governments, multilateral agencies and others abroad
to reduce principal and interest arrearages on their debt. The commitment on the
part of these governments, agencies and others to make such disbursements may be
conditioned on a  sovereign debtor's implementation  of economic reforms  and/or
economic  performance  and  the  timely service  of  such  debtor's obligations.
Failure to implement such reforms,  achieve such levels of economic  performance
or repay principal or interest when due, may result
 
                  Statement of Additional Information Page 20
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
in  the cancellation  of such  third parties' commitments  to lend  funds to the
sovereign debtor, which may further impair such debtor's ability or  willingness
to timely service its debts.
 
In  recent years, some of the Latin American countries in which the Fund expects
to invest have encountered difficulties in servicing their Sovereign Debt.  Some
of  these  countries  have withheld  payments  of interest  and/or  principal of
Sovereign Debt. These difficulties  have also led  to agreements to  restructure
external  debt obligations -- in particular, commercial bank loans, typically by
rescheduling principal  payments,  reducing  interest rates  and  extending  new
credits to finance interest payments on existing debt. In the future, holders of
Sovereign  Debt may be requested to participate in similar reschedulings of such
debt.
 
The ability  of Latin  American governments  to make  timely payments  on  their
Sovereign  Debt is likely  to be influenced  strongly by a  country's balance of
trade and its access to trade  and other international credits. A country  whose
exports  are concentrated in a few commodities  could be vulnerable to a decline
in the  international prices  of  one or  more  of such  commodities.  Increased
protectionism  on the part of a  country's trading partners could also adversely
affect its exports.
 
    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. In addition, for companies that keep accounting records
in local currency, inflation accounting  rules in some Latin American  countries
require,  for  both  tax  and  accounting  purposes,  that  certain  assets  and
liabilities be restated on the company's balance sheet in order to express items
in terms  of currency  of constant  purchasing power.  Inflation accounting  may
indirectly  generate  losses or  profits. There  is substantially  less publicly
available  information  about  foreign   companies,  including  Latin   American
companies,  and  the  governments of  Latin  American countries  than  there are
reports and  ratings published  about U.S.  companies and  the U.S.  government.
Issuers  of securities in foreign jurisdictions are generally not subject to the
same degree of regulation as  are U.S. issuers with  respect to such matters  as
restrictions  on market  manipulation, insider trading  rules, shareholder proxy
requirements and timely disclosure of information.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
The Fund's investment objectives  may not be changed  without the approval of  a
majority of its outstanding voting securities. As defined in the 1940 Act and as
used  in  this Statement  of Additional  Information 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 and (ii) more than 50%  of the outstanding shares. In addition,  the
Fund  has adopted the following fundamental  investment limitations that may not
be changed without approval of a majority of its outstanding voting securities.
 
The Fund may not:
 
        (1) issue senior  securities or  borrow money  in amounts  in excess  of
    those permitted under the 1940 Act;
 
        (2) make an investment in any one industry if the investment would cause
    the aggregate value of all investments in such industry to equal 25% or more
    of  the Fund's total assets; provided that this limitation does not apply to
    investments in securities issued or  guaranteed by the U.S. government,  its
    agencies or instrumentalities;
 
                  Statement of Additional Information Page 21
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
        (3)  purchase  securities  on  margin,  except  for  short-term  credits
    necessary for clearance of portfolio  transactions and except that the  Fund
    may  make margin  deposits in  connection with  its use  of options, futures
    contracts, options  on futures  contracts,  forward currency  contracts  and
    other financial instruments;
 
        (4)  engage in the business of underwriting securities of other issuers,
    except to the extent that, in  connection with the disposition of  portfolio
    securities,  the Fund may be deemed  an underwriter under federal securities
    laws and except that the Fund may write options;
 
        (5) make short sales of securities or maintain a short position,  except
    that  the Fund may  maintain short positions  in connection with  its use of
    options,  futures  contracts,  options  on  futures  contracts  and  forward
    currency contracts and may sell short "against the box;"
 
        (6)  purchase  or  sell  real  estate  (including  real  estate  limited
    partnership interest),  provided  that the  Fund  may invest  in  securities
    secured  by, or issued by companies that  invest in real estate or interests
    therein;
 
        (7) purchase or sell commodities or commodity contracts, except that the
    Fund may  sell  commodities received  upon  the exercise  of  warrants,  may
    purchase  or  sell  financial  and currency  futures  contracts  and options
    thereon, may purchase and sell forward contracts, may engage in transactions
    in  foreign  currencies  and  may  purchase  or  sell  options  on   foreign
    currencies; or
 
        (8)  make  loans,  except  through loans  or  portfolio  instruments and
    repurchase agreements, provided  that for purposes  of this restriction  the
    acquisition  of  bonds, debentures  or other  debt instruments  or interests
    therein and  investment  in government  obligations,  short-term  commercial
    paper,  certificates of deposit and bankers' acceptances shall not be deemed
    to be the making of a loan.
 
For purposes of the concentration policy of the Fund contained in limitation (2)
above, the Fund intends  to comply with the  SEC staff position that  securities
issued  or guaranteed  as to  principal and interest  by any  one single foreign
government,  or  by  all  supranational  organizations  in  the  aggregate,  are
considered to be securities of issuers in the same industry.
 
In  addition, to  comply with  federal tax  requirements for  qualification as a
"regulated investment company" ("RIC"), the  Fund's investments will be  limited
so that, at the close of each quarter of its taxable year, (a) not more than 25%
of  the value of its total assets is  invested in the securities (other than U.S
government securities or the securities of other RICs) of any one issuer and (b)
at least 50% of the  value of its total assets  is represented by cash and  cash
items,   U.S.  government  securities,  securities   of  other  RICs  and  other
securities, with these other securities limited,  in respect of any one  issuer,
to  an amount that does not exceed 5% of  the value of its total assets and that
does not represent more than 10%  of the issuer's outstanding voting  securities
("Diversification  Requirements"). These tax-related  limitations may be changed
by the  Company's Board  of Directors  to the  extent necessary  to comply  with
changes to applicable tax requirements.
 
   
The  Fund's other  investment policies and  limitations described  herein may be
changed by  vote  of  the  Company's  Board  of  Directors  without  shareholder
approval,  provided that any such policies and  limitations as so amended do not
conflict with the Fund's fundamental investment limitations.

                             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.
    
 
                  Statement of Additional Information Page 22
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
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 contracts. A  commission paid to such  brokers may be higher
than that which another  qualified broker would have  charged for effecting  the
same  transaction, provided that the 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
benefits 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 U.S. transactions. There generally is less government
supervision and regulation of  foreign stock exchanges and  brokers than in  the
United  States. Foreign security settlements may in some instances be subject to
delays and related administrative uncertainties.
 
Foreign equity securities may  be held by  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 December 31,  1997, 1996 and  1995, the Predecessor
Fund  paid  aggregate  brokerage  commissions  of  $2,212,022,  $1,580,879   and
$1,311,090, respectively.
    
 
                  Statement of Additional Information Page 23
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS 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 December
31, 1997 and 1996, the Predecessor Fund's portfolio turnover rates were 184% and
138%, 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.
 
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.
 
In  approving the Plans, the Directors determined that the adoption of each Plan
was in the best interests of the shareholders of the Fund. Agreements related to
the Plans must  also be  approved by  such vote  of the  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.
 
                  Statement of Additional Information Page 27
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
GT Global receives any contingent deferred sales charges payable with respect to
redemptions of Class B shares and certain Class A shares.
 
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.
 
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 that 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 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.
 
                  Statement of Additional Information Page 28
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
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.

<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
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 which 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 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 you  and your  spouse's
earnings  exceed  a certain  level, you  may also  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  advisor  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 a  series  of substantially  equal  periodic payments,  generally  is
subject to regular wage withholding or withholding at the rate of 10% (depending
 
                  Statement of Additional Information Page 30
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
on  the type and  amount of the distribution),  unless you elect  to to have any
withholding apply. Please consult your tax advisor 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 Code 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 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.

- --------------------------------------------------------------------------------
 
GENERAL
To continue to  qualify for treatment  as a 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,  and taxes paid to, foreign countries  and
U.S.  possessions if  it makes  this election.  Pursuant to  the Taxpayer Relief

Act of  1997 ("Tax  Act"), individuals  who have  no more  than $300  ($600  for
married  persons filing  jointly) of creditable  foreign taxes  included on Form
1099 and all of whose foreign source of income is "qualified passive income" may
elect each year to be exempt  from the extremely complicated foreign tax  credit
limitation and will be able to claim a foreign tax credit without having to file
the detailed Form 1116 that otherwise is required.
 
PASSIVE FOREIGN INVESTMENT COMPANIES
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 it 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 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  of the Predecessor  Fund (recomputed for  Class A  and
Class B shares to reflect the deduction of the maximum sales charge of 4.75% for
Class  A shares  and the deduction  of the applicable  contingent deferred sales
charge for Class B shares), 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.

Aggregate Non-Standardized Return ("T") is computed by using the ending value of
the account  ("VOA")  of  a  hypothetical initial  investment  of  $1,000  ("P")
according  to the following  formula: T =  (VOA/P)-1. Aggregate Non-Standardized
Return assumes reinvestment  of dividends  and other distributions  and, as  set
forth below, may or may not take sales charge into account.
 
   
The aggregate Non-Standardized Return of the Predecessor Fund (not recomputed to

OTHER INFORMATION REGARDING STANDARDIZED AND NON-STANDARDIZED RETURNS
The Standardized and Non-Standardized Return  Data are based on the  performance
of  the Predecessor  Fund as a  closed-end investment  company. The Standardized
Return Data,  however, have  been recomputed  to reflect  the deduction  of  the
current  maximum sales charge of  4.75% for Class A  shares and the deduction of
the applicable deferred sales charge of 5.00% for Class B shares, both of  which
went  into effect on  November 1, 1997.  Future performance of  the Fund will be
effected by expenses that it  will incur as a  series of an open-end  investment
company.  An investor's  actual return  may also  be affected  by the  Fund's 2%
redemption fee, which will be imposed on certain redemptions and exchanges until
May 1, 1998.
 
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 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 United States.
 
        (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,

GT  Global believes that this information may be useful to investors considering
whether and to what extent to  diversify their investments 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  of  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
rankings by DALBAR Surveys, Inc. in advertising materials.
 
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 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
performance  of  these capital  markets  is based  on  the returns  of different
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  the  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.

involving the sale of state-owned companies to the private sector.
    
 
In advertising and sales materials, GT  Global may make reference to or  discuss

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 bond  because
    margins  of  protection  may  not  be  as  large  as  in  Aaa  securities or
    fluctuation of protective elements may be of greater amplitude or there  may
    be  other elements  present which  make the  long-term risk  appear somewhat
    larger than the Aaa securities.
 
        A  --  Bonds  which  are  rated  A  possess  many  favorable  investment
    attributes  and  are  to be  considered  as  upper-medium-grade obligations.
    Factors giving security to principal  and interest are considered  adequate,
    but  elements may  be present which  suggest a  susceptibility to impairment
    some time in the future.
 
        Baa --  Bonds  which  are  rated  Baa  are  considered  as  medium-grade
    obligations,  (i.e., they are neither  highly protected nor poorly secured).
    Interest payments and principal security appear adequate for the present but
    certain protective  elements may  be lacking  or may  be  characteristically
    unreliable  over  any  great length  of  time. Such  bonds  lack outstanding
    investment characteristics and in  fact have speculative characteristics  as
    well.
 
        Ba  -- Bonds which are rated Ba are judged to have speculative elements;
    their future cannot be considered  as well-assured. Often the protection  of
    interest  and principal payments may be  very moderate, and thereby not well
    safeguarded during other good and bad times over the future. Uncertainty  of
    position characterizes bonds in this class.
 
        B  --  Bonds which  are rated  B generally  lack characteristics  of the
    desirable investment. Assurance  of interest  and principal  payments or  of
    maintenance  of other terms of the contract over any long period of time may
    be small.
 
        Caa -- Bonds which are rated Caa  are of poor standing. Such issues  may
    be  in default or  there may be  present elements of  danger with respect to
    principal or interest.
 
        Ca  --  Bonds  which  are  rated  Ca  represent  obligations  which  are
    speculative in a high degree. Such issues are often in default or have other
    marked shortcomings.
 
        C  -- Bonds which are  rated C are the lowest  rated class of bonds, and
    issues so rated can be regarded  as having extremely poor prospects of  ever
    attaining any real investment standing.
 
ABSENCE  OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may  be for reasons unrelated  to the quality of  the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1. An application for rating was not received or accepted.
 
    2.  The issue or issuer  belongs to a group  of securities or companies that
are not rated as a matter of policy.
 
    3. There is a lack of essential data pertaining to the issue or issuer.
 
    4. The issue was privately placed, in which case the rating is not published
in Moody's publications.
 
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.

                       GT GLOBAL DEVELOPING MARKETS FUND
 
Note: Moody's applies  numerical modifiers, 1,  2 and 3  in each generic  rating
classification  from Aa to Caa. The modifier  1 indicates that the Company ranks
in the higher end  of its generic  rating category; the  modifier 2 indicates  a
mid-range  ranking; and the modifier  3 indicates that the  Company ranks in the
lower end of its generic rating category.
 
    STANDARD & POOR'S, a  division of The  McGraw-Hill Companies, Inc.  ("S&P"),
rates  the securities debt of various  entities in categories ranging from "AAA"
to "D"  according  to quality.  Investment  grade  ratings are  the  first  four
categories:
 
        AAA -- An obligation rated "AAA" has the highest rating assigned by S&P.
    The obligor's capacity to meet its financial commitment on the obligation is
    extremely strong.
 
        AA   --  An  obligation  rated  "AA"  differs  from  the  highest  rated
    obligations only  in a  small degree.  The obligor's  capacity to  meet  its
    financial commitment on the obligation is very strong.
 
        A -- An obligation rated "A" is somewhat more susceptible to the adverse
    effects of changes in circumstances and economic conditions than obligations
    in higher rated categories.
 
        BBB   --  An   obligation  rated  "BBB"   exhibits  adequate  protection
    parameters. However, adverse economic  conditions or changing  circumstances
    are  more likely to lead  to a weakened capacity of  the obligor to meet its
    financial commitment on the obligation.
 
        BB, B, CCC, CC, C -- Obligations  rated "BB," "B," "CCC," "CC," and  "C"
    are   regarded  as  having  significant  speculative  characteristics.  "BB"
    indicates the least degree  of speculation and "C"  the highest. While  such
    obligations  will likely  have some quality  and protective characteristics,
    these may be outweighed by large uncertainties or major exposures to adverse
    conditions.
 
        BB -- An  obligation rated "BB"  is less vulnerable  to nonpayment  than
    other  speculative issues. However, it  faces major ongoing uncertainties or
    exposure to adverse business, financial, or economic conditions which  could
    lead  to the obligor's inadequate capacity  to meet its financial commitment
    on the obligation.
 
        B --  An obligation  rated "B"  is more  vulnerable to  nonpayment  than
    obligations  rated "BB," but the obligor  currently has the capacity to meet
    its financial commitment on the obligation. Adverse business, financial,  or
    economic conditions will likely impair the obligor's capacity or willingness
    to meet its financial commitment on the obligation.
 
        CCC  -- An obligation rated "CCC" is currently vulnerable to nonpayment,
    and is dependent upon favorable business, financial, and economic conditions
    for the obligor to meet its  financial commitment on the obligation. In  the
    event of adverse business, financial, or economic conditions, the obligor is
    not  likely to  have the  capacity to meet  its financial  commitment on the
    obligation.
 
        CC --  An  obligation  rated  "CC" is  currently  highly  vulnerable  to
    nonpayment.
 
        C  -- The "C" rating may be used to cover a situation where a bankruptcy
    petition has been filed  or similar action has  been taken, but payments  on
    this obligation are being continued.
 
        D  -- An  obligation rated  "D" is  in payment  default. The  "D" rating
    category is used when payments on an obligation are not made on the date due
    even if the  applicable grace period  has not expired,  unless S&P  believes
    that  such payments will  be made during  such grace period.  The "D" rating
    also will be used upon the filing of a bankruptcy petition or the taking  of
    a similar action if payments on an obligation are jeopardized.
 
PLUS  (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by the
addition of a  plus or minus  sign to  show relative standing  within the  major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient information on which to base a rating, or that S&P does not rate  a
particular type of obligation as a matter of policy.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
    MOODY'S  employs  the  designation "Prime-1"  to  indicate  commercial paper
having a superior ability for  repayment of senior short-term debt  obligations.
Prime-1  repayment  ability will  often be  evidenced by  many of  the following
characteristics: leading market positions  in well-established industries;  high
rates  of return on  funds employed; conservative  capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in  earnings
coverage  of  fixed financial  charges and  high  internal cash  generation; and
well-established access to a range of  financial markets and assured sources  of
alternate liquidity. Issues rated Prime-2 have a strong ability for repayment of
senior  short-term debt obligations. This normally  will be evidenced by many of
the characteristics cited  above but  to a  lesser degree.  Earnings trends  and
coverage  ratios, while sound, may be  more subject to variation. Capitalization
characteristics, while  still  appropriate, may  be  more affected  by  external
conditions. Ample alternate liquidity is maintained.
 
                  Statement of Additional Information Page 44
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS 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."
 
COMMERCIAL PAPER RATINGS
The Fund may invest only in high quality commercial paper, i.e. commercial paper
rated Prime-1 by Moody's, A-1 by S&P,  or, if unrated, judged by the Manager  to

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
- --------------------------------------------------------------------------------
 
To the Shareholders and Board of Directors of
GT Global Developing Markets Fund ("Fund"):
 
We have audited the accompanying statement of assets and liabilities of GT
Global Developing Markets Fund (formerly G.T. Global Developing Markets Fund,
Inc.), including the portfolio of investments, as of October 31, 1997, the
related statement of operations for the ten months then ended and for the year
ended December 31, 1996, the statements of changes in net assets for the ten
months then ended and for each of the two years in the period ended December 31,
1996, and the financial highlights for each of the periods indicated therein.
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 custodians 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 Developing Markets Fund as of October 31, 1997, the results of its
operations for the ten months then ended and for the year ended December 31,
1996, the changes in its net assets for the ten months then ended and for each
of the two years in the period ended December 31, 1996, and the financial
highlights for the periods indicated therein, in conformity with generally
accepted accounting principles.

                              FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES
GT Global Developing Markets Fund ("Fund") is a separate series of G.T.
Investment Funds, Inc. ("Company"). The Company is organized as a Maryland
corporation and is registered under the Investment Company Act of 1940, as
amended ("1940 Act"), as an open-end management investment company. The Company
has thirteen series of shares in operation, each series corresponding to a
distinct portfolio of investments.
 
On October 31, 1997, at the close of business, the Fund acquired the assets and
assumed the liabilities of G.T. Global Developing Markets Fund, Inc., a Maryland
corporation registered under the 1940 Act as a non-diversified closed-end
management investment company ("Predecessor Fund"), in exchange for Class A
shares of the Fund in a tax-free reorganization of the Predecessor Fund.
Shareholders of the Predecessor Fund approved the reorganization on October 20,
1997. Prior to October 28, 1997 the Closed-End Fund's shares traded on the New
York Stock Exchange. As a result of the reorganization of the Predecessor Fund
into the Fund, the Fund has a fiscal year end of October 31 to coincide with the
fiscal years of the other series of the Company. Class A shares of the Fund
issued in connection with the reorganization of the Predecessor Fund will be
subject to a 2% redemption fee for redemptions until May 1, 1998. The financial
statements presented are the financial statements for the Predecessor Fund.
 
Commencing November 1, 1997, the Fund began to offer Class A, Class B, and
Advisor Class shares, each of which has equal rights as to assets and voting
privileges except that 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 Fund 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
asked prices for securities or, if such prices are not available, at prices for
securities of comparative 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 with a maturity of 60 days
or less are valued at amortized cost, adjusted for foreign exchange translation
and market fluctuation, 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
Fund'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 Fund'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, 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
existing 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 and losses arise from sales and
maturities of short-term investments, forward foreign currency contracts, sales
of foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the differences 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

                       GT GLOBAL DEVELOPING MARKETS FUND
 
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 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. The Fund could be exposed to risk if a counterparty is
unable to meet the terms of a 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, unless a quotation from only one
broker is available, in which case only that broker's price will be used. 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 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 and
bond markets 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 and bond
markets 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 of income on securities, 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 market risk if the other party 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 $29,571,465
were on loan to brokers. The loans were secured by cash collateral of
$33,239,507 received by the Fund. For international
 
                                      F20
<PAGE>
                       GT GLOBAL DEVELOPING MARKETS FUND
 
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 each loan. For the period ended October 31, 1997, the Fund received
securities lending income of $302,308 which was used to reduce the Fund's
custodian fees 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, and unrealized appreciation of securities held, or excise tax on income
and capital gains. The Fund currently has a capital loss carryforward of
$54,472,976 which expires in 2003.
 
(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) DEFERRED ORGANIZATIONAL EXPENSES
Expenses incurred by the Fund in connection with its organization, its
registration with the Securities and Exchange Commission and with various states
aggregated $353,775. These expenses are being amortized on a straightline basis
over a five-year period.
 
(L) FOREIGN SECURITIES
There are certain additional considerations and risks associated with investing
in foreign securities and currency transactions that are not inherent in
investments of domestic origin. The Fund's investments in emerging market
countries may involve greater risks than investments in more developed markets
and the prices 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.
 
(M) 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.
 
(N) 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. At the end of the period, restricted
securities (excluding 144A issues) are shown at the end of the Fund's Portfolio
of Investments.
 
(O) SECURITIES PURCHASED ON A WHEN-ISSUED OR FORWARD COMMITMENT BASIS
The Fund may trade securities on a when-issued or forward commitment basis, with
payment and delivery scheduled for a future date. These transactions are subject
to market fluctuations and are subject to the risk that the value at delivery
may be more or less than the trade date purchase price. Although the Fund will
generally purchase these securities with the intention of acquiring such
securities, they may sell such securities before the settlement date. These
securities are identified on the accompanying Portfolio of Investments. The Fund
has purchased and sold when-issued securities during the period and has set
aside liquid securities as collateral for these commitments.
 
(P) LINE OF CREDIT
The Fund, along with certain other funds advised and/or administered by the
Manager ("GT Funds"), has a line of credit with each of BankBoston and State
Street Bank & Trust Company. The arrangements with the banks allow 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 the Fund's total assets. On October 31,
1997, the Fund had no loans outstanding.
 
For the period 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 $12,607,909, with a weighted average interest rate of 6.29%.
Interest expense for the Fund for the period ended October 31, 1997 was $24,241,
and is included in "Other Expenses" on the Statement of Operations.
 
2. RELATED PARTIES
 
(A) PREDECESSOR FUND THROUGH OCTOBER 31, 1997
Chancellor LGT Asset Management, Inc. was the Predecessor Fund's investment
manager and administrator. The Predecessor Fund paid the Manager investment
management fees, which were computed weekly and paid monthly, at the annualized
rate of 1.40% of the funds average weekly net assets. The Manager also acted as
administrator of the Predecessor Fund and paid the Manager administration fees,
which were computed and paid monthly, at an annualized rate of 0.25% of the
Fund's average weekly net assets.

monthly fee for these services to the Manager was a percentage, not to exceed
0.03% annually, of the Predecessor Fund's average daily net assets. The annual
fee rate was 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 Predecessor Fund's average
daily net assets.
 
The Predecessor Fund paid each of its Directors who was not an employee, officer
or director of the Manager or any of its affiliated companies $5,000 per year
plus $300 for each meeting of the board or any committee thereof attended by the
Director.
 
(B) THE FUND COMMENCING NOVEMBER 1, 1997
Chancellor LGT Asset Management, Inc. is the Fund's investment manager and
administrator. The Fund pays the Manager investment management and
administration fees 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. 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 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. 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 0.50% 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.
 
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 2.00%, 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 the 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.
 
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 or any of its affiliated companies $5,000 per year plus
$300 for each meeting of the board or any committee thereof attended by the
Director.
