                             GT GLOBAL INCOME FUNDS
                          PROSPECTUS -- MARCH 1, 1998
- --------------------------------------------------------------------------------
 
GT GLOBAL GOVERNMENT INCOME FUND ("GOVERNMENT INCOME FUND") seeks a high level
of current income by investing primarily in high quality U.S. and foreign
government debt securities. The Fund's secondary objectives are capital
appreciation and protection of principal through active management of its
maturity structure and currency exposure.
 
GT GLOBAL STRATEGIC INCOME FUND ("STRATEGIC INCOME FUND") primarily seeks high
current income and secondarily seeks capital appreciation. The Fund allocates
its assets among debt securities of issuers in: (1) the United States; (2)
developed foreign countries; and (3) emerging markets.
 
GT GLOBAL HIGH INCOME FUND ("HIGH INCOME FUND") primarily seeks high current
income and secondarily seeks capital appreciation by investing all of its
investable assets in the Global High Income Portfolio ("Portfolio"), which, in
turn, invests primarily in the debt securities of issuers located in emerging
markets. The Portfolio's investment objectives are identical to those of the
Fund.
 
There can be no assurance that any Fund or the Portfolio will achieve its
investment objectives. The investment experience of the High Income Fund will
correspond directly with the investment experience of the Portfolio.
 
FUND SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR ENDORSED OR GUARANTEED BY,
ANY BANK, NOR ARE THEY FEDERALLY INSURED OR OTHERWISE PROTECTED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY.
 
The Funds and the Portfolio are managed and/or administered 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 Funds are designed for long-term investors and not as trading vehicles, do
not represent a complete investment program and are not suitable for all
investors. An investment in any of the Funds involves risk factors that should
be reviewed carefully by potential investors. The Strategic Income Fund and the
Portfolio both are authorized to borrow money for investment purposes, which
would increase the volatility of their performance and involves additional
risks. See "Investment Objectives and Policies" and "Risk Factors."
 
THE STRATEGIC INCOME FUND INVESTS UP TO 50% OF ITS TOTAL ASSETS, AND THE
PORTFOLIO INVESTS UP TO 100% OF ITS TOTAL ASSETS, IN LOWER QUALITY AND UNRATED
FOREIGN GOVERNMENT BONDS WHOSE CREDIT QUALITY IS GENERALLY CONSIDERED THE
EQUIVALENT OF U.S. CORPORATE DEBT SECURITIES COMMONLY KNOWN AS "JUNK BONDS."
INVESTMENTS OF THIS TYPE ARE SUBJECT TO A GREATER RISK OF LOSS OF PRINCIPAL AND
INTEREST. PURCHASERS SHOULD CAREFULLY ASSESS THE RISKS ASSOCIATED WITH AN
INVESTMENT IN THESE FUNDS. SEE "INVESTMENT OBJECTIVES AND POLICIES" AND "RISK
FACTORS."
 
This Prospectus sets forth concisely information an investor should know before
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 Funds and the Portfolio:   Each Fund is a non-diversified series of G.T. Investment Funds,
                               Inc. (the "Company"). The Portfolio is a non-diversified, open-end
                               management investment company.
 
Investment Objectives:         The Government Income Fund primarily seeks high current income and
                               secondarily seeks capital appreciation and protection of
                               principal. The Strategic Income Fund and the High Income Fund
                               primarily seek high current income and secondarily seek capital
                               appreciation.
 
Principal Investments:         The Government Income Fund invests primarily in high quality U.S.
                               and foreign government debt obligations.
 
                               The Strategic Income Fund allocates its assets among debt
                               securities of issuers in: (1) the United States; (2) developed
                               foreign countries; and (3) emerging markets, and selects
                               particular securities in each sector based on their relative
                               investment merit.
 
                               The High Income Fund invests all of its investable assets in the
                               Portfolio, which, in turn, invests primarily in debt securities of
                               issuers located in emerging markets.
 
Principal Risk Factors:        There is no assurance that the Funds or the Portfolio will achieve
                               their investment objectives. Each Fund's net asset value will
                               fluctuate, reflecting fluctuations in the market value of its or
                               its corresponding Portfolio's portfolio holdings. The value of
                               debt securities held by the Government Income Fund, Strategic
                               Income Fund and Portfolio generally fluctuates inversely with
                               interest rate movements.
 
                               The Government Income Fund, Strategic Income Fund and Portfolio
                               will invest in foreign securities. Investments in foreign
                               securities involve risks relating to political and economic
                               developments abroad and the differences between the regulations to
                               which U.S. and foreign issuers are subject. Individual foreign
                               economies also may differ favorably or unfavorably from the U.S.
                               economy. Changes in foreign currency exchange rates will affect a
                               Fund's or the Portfolio's net asset value, earnings and gains and
                               losses realized on sales of securities. Securities of foreign
                               companies may be less liquid and their prices more volatile than
                               those of securities of comparable U.S. companies. The Portfolio
                               will normally invest at least 65% of its total assets in debt
                               securities of issuers in emerging markets and the Strategic Income
                               Fund may invest in such securities. Such investments entail
                               greater risks than investing in securities of issuers in developed
                               markets.
 
                               The Government Income Fund, Strategic Income Fund and Portfolio
                               may engage in certain foreign currency, options and futures
                               transactions to attempt to hedge against the overall level of
                               investment and currency risk associated with its present or
                               planned investments. Such transactions involve certain risks and
                               transaction costs.

                               assets, and the Portfolio may invest up to 100% of its total
                               assets, in debt securities rated below investment grade or, if not
                               rated, determined by the Manager to be of comparable quality.
                               Investments of this type are subject to greater risk of loss of
                               principal and interest.

(1) THESE TABLES ARE INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE VARIOUS
    COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN A FUND. Long-term
    shareholders may pay more than the economic equivalent of the maximum
    front-end sales charge permitted by the National Association of Securities
    Dealers, Inc. rules regarding investment companies. THE "HYPOTHETICAL
    EXAMPLE" IS NOT A REPRESENTATION OF PAST OR FUTURE EXPENSES. THE FUNDS' AND
    THE PORTFOLIO'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN. The
    tables and the assumption in the Hypothetical Example of a 5% annual return
    are required by regulation of the SEC applicable to all mutual funds; the 5%
    annual return is not a prediction of and does not represent the Funds' or
    the Portfolio's projected or actual performance.
 
(2) Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge generally
    declines by 1% annually thereafter, reaching zero after six years. See "How
    to Invest."
 
(3) Expenses are based on the Funds' fiscal year ended October 31, 1997. "Other
    expenses" include custody, transfer agency, legal, audit and other operating
    expenses. See "Management" herein and the Statement of Additional
    Information for more information. The Funds also offer Advisor Class shares,
    which are not subject to 12b-1 distribution and service fees, to certain
    categories of investors. See "How to Invest." The Board of Directors of the
    Company believes that the aggregate per share expenses of the High Income
    Fund and its corresponding Portfolio will be less than or approximately
    equal to the expenses which the Fund would incur if the assets of that Fund
    were invested directly in the type of securities being held by the
    Portfolio.
 
(4) Assumes payment of maximum sales charge by the investor.
 
(5) Assumes deduction of the applicable contingent deferred sales charge.

their agencies and instrumentalities. Its secondary objectives are capital
appreciation and protection of principal through active management of its
maturity structure and currency exposure.
 
At least 65% of the Fund's total assets normally are invested in debt
obligations issued or guaranteed by the U.S. or foreign governments (including
foreign states, provinces or municipalities) or their agencies, authorities or
instrumentalities. For purposes of this policy, the Fund considers debt
obligations of supranational entities organized or supported by several national
governments, such as the World Bank and the Asian Development Bank, to be
"government securities."
 
The Fund invests primarily in high quality government debt securities. "High
quality" debt securities are those rated in the top two ratings categories of
Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's, a division of
The McGraw-Hill Companies, Inc. ("S&P"), or, if not rated, determined to be of
comparable quality by the Manager. A description of Moody's and S&P ratings is
included in the Appendix to this Prospectus.
 
The Fund currently contemplates that it will invest principally in obligations
of the United States, Canada, Japan, the Western European nations, New Zealand
and Australia, as well as in multinational currency units. Under normal market
conditions, the Fund invests in issues of not less than three different
countries; investments in the securities of any one country, other than the
United States, normally represent no more than 40% of the Fund's total assets.
The Fund will not invest in a foreign currency or in securities denominated in a
foreign currency if such currency is not at the time of investment considered by
the Manager to be fully exchangeable into U.S. dollars (or a multinational
currency unit) without legal restriction.
 
The Fund may also invest up to 35% of its total assets in: (1) foreign
government securities that are not high quality but are rated at least
"investment grade," i.e., rated within the four highest ratings categories of
Moody's or S&P or, if not rated, determined by the Manager to be of comparable
quality; (2) corporate debt obligations of U.S. or foreign issuers rated at
least investment grade by Moody's or S&P, including debt obligations convertible
into equity securities or having attached warrants or rights to purchase equity
securities; and (3) common stocks, preferred stocks and warrants to acquire such
securities, provided that the Fund will not invest more than 20% of its total
assets in such securities.
 
STRATEGIC INCOME FUND
The Strategic Income Fund primarily seeks high current income and secondarily
seeks capital appreciation.
 
The Fund invests in debt securities of issuers in: (1) the United States; (2)
developed foreign countries; and (3) emerging markets. The Fund selects debt
securities from those issued by governments, their agencies and
instrumentalities; central banks; and commercial banks and other corporate
entities. Debt securities in which the Fund may invest include bonds, notes,
debentures, and other similar instruments. The Fund normally invests at least
50% of its net assets in U.S. and foreign debt and other fixed income securities
that, at the time of purchase, are rated at least investment grade by Moody's or
S&P or, if not rated, determined by the Manager to be of comparable quality. No
more than 50% of the Fund's total assets may be invested in securities rated
below investment grade. Such securities involve a high degree of risk and are
predominantly speculative. They are the equivalent of high yield, high risk
bonds, commonly known as "junk bonds." The Fund may also invest in securities
that are in default as to payment of principal and/or interest.
 
The Fund's investments in emerging market securities may consist substantially
of Brady Bonds (see "General Policies -- Brady Bonds," below) and other
sovereign debt securities issued by emerging market governments that are traded
in the markets of developed countries or groups of developed countries. The
Manager may invest in debt securities of emerging market issuers that it
determines to be suitable investments for the Fund without regard to ratings.
Currently, the substantial majority of emerging market debt securities are
considered to have a credit quality below investment grade. The Fund also may
invest in below-investment grade debt securities of corporate

issuers in the United States and in developed foreign countries, subject to the
overall 50% limitation.
 
HIGH INCOME FUND
The High Income Fund primarily seeks high current income, and secondarily seeks
capital appreciation. It seeks its objectives by investing all of its investable
assets in the Portfolio, which in turn seeks the same objectives as the Fund by
normally investing at least 65% of its total assets in debt securities of
issuers in emerging markets.
 
The Portfolio intends to invest in the following types of debt securities:
bonds, notes and debentures of emerging market governments; securities issued or
guaranteed by such governments' agencies or instrumentalities; securities issued
or guaranteed by the central banks of emerging market countries; and securities
issued by other banks and companies in such countries and securities denominated
in or indexed to the currencies of emerging markets. Under current market
conditions, the Portfolio expects its investments in emerging market securities
to consist substantially of Brady Bonds (see "General Policies -- Brady Bonds,"
below) and other sovereign debt securities.
 
The Portfolio may also invest up to 35% of its total assets in (1) equity
securities of issuers in emerging markets included in the list below under the
caption "Emerging Markets"; (2) equity and debt securities of issuers in
developed countries, including the United States; (3) securities of issuers in
emerging markets not included in the emerging markets list, if investing therein
becomes feasible and desirable subsequent to the date of this Prospectus; and
(4) cash and money market instruments. In evaluating investments in securities
of issuers in developed markets, the Manager will consider, among other things,
the business activities of the issuer in emerging markets and the impact that
developments in emerging markets are likely to have on the issuer's financial
condition.
 
Under normal circumstances, substantially all of the Portfolio's assets will be
invested in debt securities of both governmental and corporate issuers in
emerging markets. Emerging markets debt securities generally are considered to
have a credit quality below investment grade, as defined above. Lower quality
securities involve a high degree of risk and are predominantly speculative.
These debt securities are the equivalent of high yield, high risk bonds,
commonly known as "junk bonds." See "Risk Factors." Many emerging market debt
securities are not rated by U.S. ratings agencies such as Moody's and S&P. The
Portfolio's ability to achieve its investment objectives is thus more dependent
on the Manager's credit analysis. The Portfolio may invest in securities that
are in default as to payment of principal and/or interest.
 
OTHER INFORMATION REGARDING THE PORTFOLIO. As previously described, investors
should be aware that the High Income Fund, unlike mutual funds that directly
acquire and manage their own portfolios of securities, seeks to achieve its
investment objectives by investing all of its investable assets in the
Portfolio, which is a separate investment company. Because the Fund will invest
only in the Portfolio, the Fund's shareholders will acquire only an indirect
interest in the investments of the Portfolio.
 
The High Income Fund may redeem its investment from the Portfolio at any time,
if the Board of Directors of the Company determines that it is in the best
interests of the Fund and its shareholders to do so. A change in the Portfolio's
investment objectives, policies or limitations that is not approved by the Board
or the shareholders of the High Income Fund could require the Fund to redeem its
interest in the Portfolio. Any such redemption could result in a distribution in
kind of portfolio securities (as opposed to a cash distribution) by the
Portfolio. In addition, a distribution in kind could result in a less
diversified portfolio of investments for the Fund and could adversely affect its
liquidity. Upon redemption, the Board would consider what action might be taken,
including the investment of all the investable assets of the Fund in another
pooled investment entity having substantially the same investment objectives as
the Fund or the retention by the Fund of its own investment adviser to manage
its assets in accordance with its investment objectives, policies and
limitations discussed herein.
 
In addition to selling an interest therein to the Fund, the Portfolio may sell
interests therein to other non-affiliated investment companies and/or other
institutional investors. All institutional investors in the Portfolio will pay a
proportionate share of the Portfolio's expenses and will invest in the Portfolio
on the same terms and conditions. However, if another investment company invests
any or all of its assets in the Portfolio, it would not be required to sell its
shares at the same public offering price as the Fund and may charge different
sales commissions. Therefore, investors in the Fund may experience different
returns than investors in another investment company that invests exclusively in
the Portfolio. As of the date of this Prospectus, the High Income Fund is the
only institutional investor in the Portfolio.
 
Investors in the Fund should be aware that the Funds' investment in the
Portfolio may be materially affected by the actions of other large investors, if
 
                               Prospectus Page 14

                             GT GLOBAL INCOME FUNDS
any, in the Portfolio. For example, as with all open-end investment companies,
if a large investor were to redeem its interest in the Portfolio, (1) the
Portfolio's remaining investors could experience higher pro rata operating
expenses, thereby producing lower returns and (2) the Portfolio's security
holdings may become less diverse, resulting in increased risk. Institutional
investors in the Portfolio that have a greater pro rata ownership interest in
the Portfolio than the Fund could have effective voting control over the
operation of the Portfolio.
 
                                GENERAL POLICIES
 
ASSET ALLOCATION. The Government Income Fund, the Strategic Income Fund and the
Portfolio each invests in debt obligations allocated among diverse markets and
denominated in various currencies, including U.S. dollars, or in multinational
currency units such as European Currency Units. The Funds are designed for
investors who wish to accept the risks entailed in such investments, which are
different from those associated with a portfolio consisting entirely of
securities of U.S. issuers denominated in U.S. dollars. The Government Income
Fund, the Strategic Income Fund and the Portfolio may purchase securities that
are issued by the government or a company or financial institution of one
country but denominated in the currency of another country (or a multinational
currency unit).
 
The Manager allocates the assets of the Government Income Fund, the Strategic
Income Fund and the Portfolio in securities of issuers in countries and in
currency denominations where the combination of fixed income market returns, the
price appreciation potential of fixed income securities and currency exchange
rate movements will present opportunities primarily for high current income and
secondarily for capital appreciation (and, in the case of the Government Income
Fund, secondarily for capital appreciation and protection of principal). In so
doing, the Manager intends to take full advantage of the different yield, risk
and return characteristics that investment in the fixed income markets of
different countries can provide for U.S. investors. Fundamental economic
strength, credit quality and currency and interest rate trends are the principal
determinants of the emphasis given to various country, geographic and industry
sectors within the Government Income Fund, the Strategic Income Fund and the
Portfolio. Securities held by the Government Income Fund, the Strategic Income
Fund and the Portfolio may be invested in without limitation as to maturity.
 
The Manager selects securities of particular issuers on the basis of its views
as to the best values then currently available in the marketplace. Such values
are a function of yield, maturity, issue classification and quality
characteristics, coupled with expectations regarding the local and world
economies, movements in the general level and term of interest rates, currency
values, political developments and variations in the supply of funds available
for investment in the world bond market relative to the demands placed upon it.
 
The Manager generally evaluates currencies on the basis of fundamental economic
criteria (e.g., relative inflation, interest rate levels and trends, growth rate
forecasts, balance of payments status and economic policies) as well as
technical and political data. The Manager may seek to protect a Fund against
such negative currency movements through the use of sophisticated investment
techniques. See "Options, Futures and Forward Currency Transactions" and "Swaps,
Caps, Floors and Collars."
 
According to the Manager, as of the date of this Prospectus, more than 50% of
the value of all outstanding government debt obligations throughout the world is
represented by obligations denominated in currencies other than the U.S. dollar.
Moreover, from time to time, the debt securities of issuers located outside the
United States have substantially outperformed the debt obligations of U.S.
issuers. Accordingly, the Manager believes that the Government Income Fund's and
the Strategic Income Fund's policy of investing in debt securities throughout
the world and the Portfolio's policy of investing in debt securities of issuers
in emerging markets may enable the achievement of results superior to those
produced by mutual funds with similar objectives to those of the Funds and the
Portfolio that invest solely in debt securities of U.S. issuers.
 
TEMPORARY DEFENSIVE STRATEGIES. The Manager may employ a temporary defensive
investment strategy if it determines such a strategy to be warranted due to
market, economic or political conditions. Pursuant to such a defensive strategy,
the Government Income Fund, the Strategic Income Fund and the Portfolio
temporarily may hold cash (U.S. dollars, foreign currencies or multinational
currency units) and/or invest up to 100% of their respective assets in high
quality debt securities or money market instruments of U.S. or foreign issuers.
In addition, for temporary defensive purposes, most or all of the Government
Income Fund's, the Strategic Income Fund's or the Portfolio's investments may be
made in the United States and denominated in U.S. dollars. To the extent the
Funds or the Portfolio employ a temporary defensive strategy, they will not be
invested so as to achieve directly their investment objectives.
 
                               Prospectus Page 15

                             GT GLOBAL INCOME FUNDS
In addition, pending investment of proceeds from new sales of Fund shares or to
meet ordinary daily cash needs, the Government Income Fund, the Strategic Income
Fund and the Portfolio may hold cash (U.S. dollars, foreign currencies or
multinational currency units) and may invest in high quality foreign or domestic
money market instruments.
 
EMERGING MARKET SECURITIES. The Strategic Income Fund and the Portfolio consider
"emerging markets" to 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. The Strategic Income
Fund and the Portfolio will consider investment in the following emerging
markets:

  Ghana           Panama         Zambia
  Greece          Paraguay       Zimbabwe
</TABLE>
 
The Strategic Income Fund and the Portfolio will not be invested in all such
markets at all times. Moreover, investing in some of those markets currently may
not be desirable or feasible, due to the lack of adequate custody arrangements,
overly burdensome repatriation requirements and similar restrictions, the lack
of organized and liquid securities markets, unacceptable political risks or for
other reasons.
 
As used in this Prospectus and the Statement of Additional Information, an
issuer in an emerging market is an entity: (i) for which the principal
securities trading market is an emerging market, as defined above; (ii) that
(alone or on a consolidated basis) derives 50% or more of its total revenue from
either goods produced, sales made or services performed in emerging markets; or
(iii) organized under the laws of, or with a principal office in, an emerging
market.
 
BRADY BONDS. The Strategic Income Fund and the Portfolio may invest in "Brady
Bonds," which are debt restructurings that provide for the exchange of cash and
loans for newly issued bonds. Brady Bonds have been issued by the countries of
Albania, Argentina, Brazil, Bulgaria, Costa Rica, Dominican Republic, Ecuador,
Ivory Coast, Jordan, Mexico, Nigeria, Panama, Peru, Philippines, Poland,
Uruguay, Venezuela and Vietnam and are expected to be issued by other emerging
market countries. As of the date of this Prospectus, the Strategic Income Fund
and the Portfolio are 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 Strategic Income Fund and the Portfolio may invest in either collateralized
or uncollateralized Brady Bonds. U.S. dollar-denominated, collateralized Brady
Bonds, which may be fixed rate par bonds or floating rate discount bonds, are
collateralized in full as to principal by U.S. Treasury zero coupon bonds having
the same maturity as the bonds. Interest payments on such bonds generally are
collateralized by cash or securities in an amount that, in the case of fixed
rate bonds, is equal to at least one year of rolling interest payments or, in
the case of floating rate bonds, initially is equal to at least one year's
rolling interest payments based on the applicable interest rate at the time of
issuance and is adjusted at regular intervals thereafter.
 
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. U.S. government securities in which
the Government Income Fund and Strategic Income Fund may invest include
mortgage-backed securities issued by agencies or instrumentalities of the U.S.
government. The Funds may also purchase privately issued mortgage-backed and
asset-backed securities. Mortgage-backed securities represent direct or indirect
interests in pools of underlying mortgage loans that are secured by real
property. Investors typically receive payments out of the interest and principal
on the underlying mortgages. Asset-backed securities are similar to
mortgage-backed securities, except that the underlying assets are other
financial assets or financial receivables, such as motor vehicle installment
sales contracts, home equity loans, leases of various types of real and personal
property and receivables from credit cards. Any privately issued mortgage-backed
and asset-backed securities purchased by Government

<PAGE>
                             GT GLOBAL INCOME FUNDS
Income Fund will be subject to the limitation of that Fund which allows no more
than 35% of its assets to be invested in securities of non-governmental issuers.
With respect to the Government Income Fund, it will only purchase such
securities if rated in the highest rating category by S&P or Moody's, or if not
rated, determined to be of comparable quality by the Manager.
 
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Strategic Income Fund and the Portfolio
may invest in fixed and floating rate loans ("Loans") arranged through private
negotiations between a foreign entity and one or more financial institutions
("Lenders"). The majority of the Fund's and the Portfolio's investments in Loans
in emerging markets is expected to be in the form of participations in Loans
("Participations") and assignments of portions of Loans from third parties
("Assignments"). Participations typically will result in the Fund and/or the
Portfolio having a contractual relationship only with the Lender, not with the
borrower government. The Fund and/or the Portfolio will have the right to
receive payments of principal, interest and any fees to which it is entitled
only from the Lender selling the Participation and only upon receipt by the
Lender of the payments from the borrower. In connection with purchasing
Participations, the Fund and/or the Portfolio generally will have no right to
enforce compliance by the borrower with the terms of the loan agreement relating
to the loan ("Loan Agreement"), nor any rights of set-off against the borrower,
and the Fund and/or the Portfolio may not directly benefit from any collateral
supporting the Loan in which it has purchased the Participation. As a result,
the Fund and/or the Portfolio will assume the credit risk of both the borrower
and the Lender that is selling the Participation.
 
In the event of the insolvency of the Lender selling a Participation, the Fund
and/or the Portfolio may be treated as a general creditor of the Lender and may
not benefit from any set-off between the Lender and the borrower. The Fund
and/or the Portfolio will acquire Participations only if the Lender
interpositioned between the Fund and/or the Portfolio and the borrower is
determined by the Manager to be creditworthy. When the Fund and/or the Portfolio
purchases Assignments from Lenders, the Fund and/or the Portfolio will acquire
direct rights against the borrower on the Loan. However, since Assignments are
arranged through private negotiations between potential assignees and assignors,
the rights and obligations acquired by the Fund and/or the Portfolio as the
purchaser of an Assignment may differ from, and be more limited than, those held
by the assigning Lender.
 
WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES. The Government Income Fund, the
Strategic Income Fund and the Portfolio may purchase debt securities on a
"when-issued" basis and may purchase or sell such securities on a "forward
commitment" basis in order to hedge against anticipated changes in interest
rates and prices. The price, which is generally expressed in yield terms, is
fixed at the time the commitment is made, but delivery and payment for the
securities take place at a later date. When-issued securities and forward
commitments may be sold prior to the settlement date, but the Funds and the
Portfolio will purchase or sell when-issued securities and forward commitments
only with the intention of actually receiving or delivering the securities, as
the case may be. No income accrues on securities that have been purchased
pursuant to a forward commitment or on a when-issued basis prior to delivery of
the securities. If a Fund or the Portfolio disposes of the right to acquire a
when-issued security prior to its acquisition or disposes of its right to
deliver or receive against a forward commitment, it may incur a gain or loss. At
the time a Fund or the Portfolio 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 its custodian and will be
marked to market daily. There is a risk that the securities may not be delivered
and that a Fund or the Portfolio may incur a loss. The Government Income Fund
may invest up to 5% of its total assets in a combination of securities purchased
on a when-issued basis or with respect to which it has entered into forward
commitment agreements.
 
The Strategic Income Fund and the Portfolio may also sell securities on a "when,
as and if issued" basis for hedging purposes. Under such a transaction, the Fund
or the Portfolio is required to deliver at a future date a security it does not
presently hold, but which it has a right to receive if the security is issued.
Issuance of the security may not occur, in which case the Fund or Portfolio
would have no obligation to the other party, and would not receive payment for
the sale. Selling securities on a "when, as and if issued" basis may reduce risk
of loss to the extent that such a sale wholly or partially offsets unfavorable
price movements on the investments being hedged. However, such sales also limit
the amount the Fund or Portfolio can receive if the "when, as and if issued"
security is in fact issued.
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND ROLL TRANSACTIONS. The Government
Income Fund may borrow from banks or may borrow
 
                               Prospectus Page 17
<PAGE>
                             GT GLOBAL INCOME FUNDS
through reverse repurchase agreements and "roll" transactions in connection with
meeting requests for the redemption of Fund shares. The Government Income Fund
also may borrow up to 5% of its total assets for temporary or emergency purposes
other than to meet redemptions. However, the Government Income Fund will not
borrow for investment purposes, nor will the Fund purchase securities while
borrowings are outstanding.
 
Both the Strategic Income Fund and the Portfolio are authorized to borrow money
from banks in an amount up to 33 1/3% of its total assets (including the amount
borrowed), less all liabilities and indebtedness other than the borrowings and
may use the proceeds of such borrowings for investment purposes. The Strategic
Income Fund and the Portfolio will borrow for investment purposes only when the
Manager believes that such borrowings will benefit the Fund or the Portfolio,
respectively, after taking into account considerations such as the costs of the
borrowing and the likely investment returns on the securities purchased with the
borrowed monies.
 
Borrowing for investment purposes is known as leveraging, which is a speculative
practice. Such borrowing by the Strategic Income Fund and the Portfolio creates
the opportunity for increased net income and appreciation but, at the same time,
involves special risk considerations. For example, leveraging might exaggerate
changes in the net asset value of Fund shares and in the yield realized by the
Fund or the Portfolio. Although the principal amount of such borrowings will be
fixed, the Fund's and the Portfolio's assets may change in value during the time
the borrowing is outstanding. By leveraging the Fund or the Portfolio, changes
in net asset values, higher or lower, may be greater in degree than if leverage
was not employed. To the extent the income derived from the assets obtained with
borrowed funds exceeds the interest and other expenses that the Fund or the
Portfolio will have to pay, the Fund's or the Portfolio's net income will be
greater than if borrowing was not used. Conversely, if the income from the
assets obtained with borrowed funds is not sufficient to cover the cost of
borrowing, the net income of the Fund or the Portfolio will be less than if
borrowing were not used, and therefore the amount available for distribution to
shareholders as dividends will be reduced. The Strategic Income Fund and the
Portfolio each expects that some of its borrowings may be made on a secured
basis.
 
In addition to the foregoing borrowings, the Strategic Income Fund and the
Portfolio each may borrow money for temporary or emergency purposes or payments
in an amount not exceeding 5% of the value of its total assets (not including
the amount borrowed) provided that the total amount borrowed by the Strategic
Income Fund or the Portfolio for any purpose does not exceed 33 1/3% of its
total assets.
 
The Funds and the Portfolio may also enter into reverse repurchase agreements
with a bank or recognized securities dealer, although the Strategic Income Fund
currently has no intention of doing so with respect to more than 5% of its total
assets. Under a reverse repurchase agreement, the Funds or the Portfolio would
sell securities and agree to repurchase them at a particular price at a future
date. At the time a Fund or the Portfolio enters into a reverse repurchase
agreement, it will establish and maintain a segregated account with an approved
custodian containing cash or liquid securities having a value not less than the
repurchase price, including accrued interest. Reverse repurchase agreements
involve the risk that the market value of the securities retained in lieu of
sale by a Fund or the Portfolio may decline below the price of the securities a
Fund or the Portfolio has sold but is obligated to repurchase. In the event the
buyer of securities under a reverse repurchase agreement files for bankruptcy or
becomes insolvent, such buyer or its trustee or receiver may receive an
extension of time to determine whether to enforce a Fund's or the Portfolio's
obligation to repurchase the securities, and a Fund's or the Portfolio's use of
the proceeds of the reverse repurchase agreement may effectively be restricted
pending such decision.
 
The Strategic Income Fund and the Portfolio also may enter into "dollar rolls,"
in which the Fund or the Portfolio sells fixed income securities for delivery in
the current month and simultaneously contracts to repurchase substantially
similar (same type, coupon and maturity) securities on a specified future date.
During the roll period, the Fund or the Portfolio would forego principal and
interest paid on such securities. The Fund or the Portfolio would be compensated
by the difference between the current sales price and the forward price for the
future purchase, as well as by the interest earned on the cash proceeds of the
initial sale. See "Investment Objectives and Policies" in the Statement of
Additional Information.
 
Reverse repurchase agreements and dollar rolls will be treated as borrowings and
will be deducted from the Strategic Income Fund's or the Portfolio's assets for
purposes of calculating compliance with the Fund's or the Portfolio's borrowing
limitation. See "Investment Limitations" in the Statement of Additional
Information.
 
SECURITIES LENDING. The Government Income Fund, the Strategic Income Fund and
the Portfolio
 
                               Prospectus Page 18
<PAGE>
                             GT GLOBAL INCOME FUNDS
may lend their respective portfolio securities to broker/dealers or to other
institutional investors. Securities lending allows a Fund to retain ownership of
the securities loaned and, at the same time, enhances a Fund's total return. At
all times a loan is outstanding, each Fund and the Portfolio requires the
borrower to maintain with the Fund's or the Portfolio's custodian, collateral
consisting of cash, U.S. government securities, or certain irrevocable letters
of credit equal to at least the value of the borrowed securities, plus any
accrued interest or such other collateral as permitted by a Fund's investment
program and regulatory agencies, and as approved by the Board. Each Fund and the
Portfolio limits its loans of portfolio securities to an aggregate of 30% of the
value of its total assets, measured at the time any such loan is made. The risks
in lending portfolio securities, as with other extensions of secured credit,
consist of possible delays in receiving additional collateral or in recovery of
the loaned securities and possible loss of rights in the collateral should the
borrower fail financially.
 
ZERO COUPON SECURITIES. The Strategic Income Fund and the Portfolio may invest
in certain zero coupon securities that are "stripped" U.S. Treasury notes and
bonds. They also may invest in zero coupon and other deep discount securities
issued by foreign governments and domestic and foreign corporations, including
certain Brady Bonds and other foreign debt and in payment-in-kind securities.
Zero coupon securities pay no interest to holders prior to maturity, and
payment-in-kind securities pay interest in the form of additional securities.
However, a portion of the original issue discount on zero coupon securities and
the "interest" on payment-in-kind securities will be included in the investing
Fund's or Portfolio's income. Accordingly, for a Fund to continue to qualify for
tax treatment as a regulated investment company and to avoid a certain excise
tax (see "Taxes" in the Statement of Additional Information), it may be required
to distribute an amount that is greater than the total amount of cash it
actually receives (or, in the case of the High Income Fund, its share of the
total amount of cash the Portfolio actually receives). These distributions must
be made from the Fund's (or, in the case of the High Income Fund, its, or its
share of, the Portfolio's) cash assets or, if necessary, from the proceeds of
sales of portfolio securities. The Fund or the Portfolio will not be able to
purchase additional income-producing securities with cash used to make such
distributions, and its current income ultimately may be reduced as a result.
Zero coupon and payment-in-kind securities usually trade at a deep discount from
their face or par value and will be subject to greater fluctuations of market
value in response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.
 
SYNTHETIC SECURITY POSITIONS. The Government Income Fund, the Strategic Income
Fund and the Portfolio may utilize combinations of futures on bonds and forward
currency contracts to create investment positions that have substantially the
same characteristics as bonds of the same type as those on which the futures
contracts are written. Investment positions of this type are generally referred
to as "synthetic securities."
 
For example, in order to establish a synthetic security position for a Fund or
the Portfolio that is comparable to owning a Japanese government bond, the
Manager might purchase futures contracts on Japanese government bonds in the
desired principal amount and purchase forward currency contracts for Japanese
Yen in an amount equal to the then current purchase price for such bonds in the
Japanese cash market, with each contract having approximately the same delivery
date.
 
The Manager might roll over the futures and forward currency contract positions
before taking delivery in order to continue the Fund's or the Portfolio's
investment position, or the Manager might close out those positions, thus
effectively selling the synthetic security. Further, the amount of each contract
might be adjusted in response to market conditions and the forward currency
contract might be changed in amount or eliminated in order to hedge against
currency fluctuations.
 
The Manager would create synthetic security positions for a Fund or the
Portfolio when it believes that it can obtain a better yield or achieve cost
savings in comparison to purchasing actual bonds or when comparable bonds are
not readily available in the market. Synthetic security positions are subject to
the risk that changes in the value of purchased futures contracts may differ
from changes in the value of the bonds that might otherwise have been purchased
in the cash market. Also, while the Manager believes that the cost of creating
synthetic security positions generally will be materially lower than the cost of
acquiring comparable bonds in the cash market, a Fund or the Portfolio will
incur transaction costs in connection with each purchase of a futures or forward
currency contract. The use of futures contracts and forward currency contracts
to create synthetic security positions also is subject to substantially the same
risks as those that exist when these instruments are used in connection with
hedging strategies. See

"Options, Futures and Forward Currency Transactions" below and "Options, Futures
and Currency Strategies" in the Statement of Additional Information.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. The Government Income Fund,
the Strategic Income Fund and the Portfolio may use forward currency contracts,
futures contracts, options on securities, options on indices, options on
currencies, and options on futures contracts to attempt to hedge against the
overall level of investment and currency risk normally associated with the
Funds' or Portfolio's investment. The Strategic Income Fund and the Portfolio
also may enter into interest rate, currency and index swaps and purchase or sell
related caps, floors and collars and other similar instruments. See "Swaps,
Caps, Floors and Collars" below. These instruments are often referred to as
"derivatives," which may be defined as financial instruments whose performance
is derived, at least in part, from the performance of another asset (such as a
security, currency or an index of securities). The Government Income Fund, the
Strategic Income Fund and the Portfolio may enter into such instruments up to
the full value of their portfolio assets. See "Risk Factors -- Options, Futures
and Forward Currency Transactions" herein and "Options, Futures and Currency
Strategies" in the Statement of Additional Information.
 
To attempt to hedge against adverse movements in exchange rates between
currencies, the Government Income Fund, the Strategic Income Fund and the
Portfolio may enter into forward currency contracts for the purchase or sale of
a specified currency at a specified future date. Such contracts may involve the
purchase or sale of a foreign currency against the U.S. dollar or may involve
two foreign currencies. The Government Income Fund, the Strategic Income Fund
and the Portfolio may enter into forward currency contracts either with respect
to specific transactions or with respect to the respective Fund's or the
Portfolio's portfolio positions. Each Fund and the Portfolio also may purchase
and sell put and call options on currencies, futures contracts on currencies and
options on such futures contracts to hedge against movements in exchange rates.
 
In addition, each Fund and the Portfolio may purchase and sell put and call
options on securities to hedge against the risk of fluctuations in the prices of
securities held by the Fund or the Portfolio or that the Manager intends to
include in the Fund's or the Portfolio's portfolio. The Funds and the Portfolio
also may purchase and sell put and call options on indices to hedge against
overall fluctuations in the securities markets generally or in a specific market
sector.
Further, the Funds and the Portfolio may sell index futures contracts and may
purchase put options or write call options on such futures contracts to protect
against a general market or market sector decline that could adversely affect
the Fund's or the Portfolio's portfolio. The Funds and the Portfolio also may
purchase index futures contracts and purchase call options or write put options
on such contracts to hedge against a general market or market sector advance and
thereby attempt to lessen the cost of future securities acquisitions. A Fund or
the Portfolio may use interest rate futures contracts and options thereon to
hedge its portfolio against changes in the general level of interest rates.
 
SWAPS, CAPS, FLOORS AND COLLARS. The Strategic Income Fund and the Portfolio may
enter into interest rate, currency and index swaps, and purchase or sell related
caps, floors and collars and other derivative instruments. The Fund and the
Portfolio expect to enter into these transactions primarily to preserve a return
or spread on a particular investment or portion of its portfolio, to protect
against currency fluctuations, as a technique for managing the portfolio's
duration (I.E., the price sensitivity to changes in interest rates) or to
protect against any increase in the price of securities the Fund or the
Portfolio anticipates purchasing at a later date. The Fund and the Portfolio
intend to use these transactions as hedges, and neither will sell interest rate
caps or floors if it does not own securities or other instruments providing an
income stream roughly equivalent to what the Fund or the Portfolio may be
obligated to pay.
 
Interest rate swaps involve the exchange by the Fund or the Portfolio with
another party of their respective commitments to pay or receive interest (for
example, an exchange of floating rate payments for fixed rate payments) with
respect to a notional amount of principal. A currency swap is an agreement to
exchange cash flows on a notional amount based on changes in the values of the
reference indices.
 
The purchase of a cap entitles the purchaser to receive payments on a notional
principal amount from the party selling the cap to the extent that a specified
index exceeds a predetermined interest rate. The purchase of an interest rate
floor entitles the purchaser to receive payments on a notional principal amount
from the party selling the floor to the extent that a specified index falls
below a predetermined interest rate or amount. A collar is a

                             GT GLOBAL INCOME FUNDS
combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.
 
INDEXED COMMERCIAL PAPER. The Strategic Income Fund and the Portfolio may invest
without limitation in commercial paper which is indexed to certain specific
foreign currency exchange rates. The terms of such commercial paper provide that
its principal amount is adjusted upwards or downwards (but not below zero) at
maturity to reflect changes in the exchange rate between two currencies while
the obligation is outstanding. The Strategic Income Fund and the Portfolio will
purchase such commercial paper with the currency in which it is denominated and,
at maturity, will receive interest and principal payments thereon in that
currency, but the amount of principal payable by the issuer at maturity will
change in proportion to the change (if any) in the exchange rate between the two
specified currencies between the date the instrument is issued and the date the
instrument matures. While such commercial paper entails the risk of loss of
principal, the potential for realizing gains as a result of changes in foreign
currency exchange rates enables the Fund and the Portfolio to hedge against a
decline in the U.S. dollar value of investments denominated in foreign
currencies while seeking to provide an attractive money market rate of return.
The Fund and the Portfolio will not purchase such commercial paper for
speculation.
 
OTHER INDEXED SECURITIES. The Government Income Fund, Strategic Income Fund and
the Portfolio may invest in certain other indexed securities, which are
securities whose prices are indexed to the prices of other securities,
securities indices, currencies, precious metals or other commodities, or other
financial indicators. Indexed securities typically, but not always, are debt
securities or deposits whose value at maturity or coupon rate is determined by
reference to a specific instrument or statistic. The performance of indexed
securities depends to a great extent on the performance of the security,
currency, or other instrument to which they are indexed, and may also be
influenced by interest rate changes in the United States and abroad. At the same
time, indexed securities are subject to the credit risks associated with the
issuer of the security, and their values may decline substantially if the
issuer's creditworthiness deteriorates. Indexed securities may be more volatile
than the underlying instruments. New forms of indexed securities continue to be
developed. Each Fund and Portfolio may invest in such securities to the extent
consistent with its investment objectives.
 
OTHER INFORMATION. Each Fund's investment objectives may not be changed without
the approval of a majority of the respective Fund's outstanding voting
securities. A "majority of the Fund's outstanding voting securities" means the
lesser of (i) 67% of the shares represented at a meeting at which more than 50%
of the outstanding shares are represented, or (ii) more than 50% of the
outstanding shares. In addition, each Fund has adopted certain investment
limitations which also may not be changed without shareholder approval. A
complete description of these limitations is included in the Statement of
Additional Information. Each Fund's other investment policies described herein
and in the Statement of Additional Information may be changed by the Company's
Board of Directors without shareholder approval.
 
The approval of the High Income Fund and of other investors in the Portfolio, if
any, is not required to change the investment objectives, policies or
limitations of the Portfolio, unless otherwise specified. Written notice shall
be provided to shareholders of the High Income Fund thirty days prior to any
changes in the Portfolio's investment objectives.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
GENERAL. There is no assurance that any Fund or the Portfolio will achieve its
investment objectives. The Funds' net asset value will fluctuate, reflecting
fluctuations in the market value of its portfolio positions and its net currency
exposure. The value of fixed income securities held by the Government Income
Fund, the Strategic Income Fund and the Portfolio generally fluctuates inversely
with interest rate movements. Longer term bonds held by the Government Income
Fund, the Strategic Income Fund or the Portfolio are subject to greater interest
rate risk.
 
NON-DIVERSIFIED CLASSIFICATION. Each Fund and the Portfolio is classified under
the Investment Company Act of 1940 (the "1940 Act") as a "non-diversified" fund.
As a result, the Government Income Fund, the Strategic Income Fund and the
Portfolio each will be able to invest in a fewer number of issuers than if it
were classified under the Investment Company Act of 1940 (the "1940 Act") as a
"diversified" fund. To the extent that a Fund or the Portfolio invests in a
smaller number of issuers, the value of each Fund's shares may fluctuate more
widely and the Funds and the Portfolio may be subject to greater investment and
credit risk with respect to their portfolios.
 
FOREIGN INVESTING. Investing in foreign securities entails certain risks. The
securities of non-U.S. issuers generally are not registered with the SEC, nor
are the issuers thereof usually subject to the SEC's reporting requirements.
Accordingly, there may be less publicly available information about foreign
securities and issuers than is available with respect to U.S. securities and
issuers. Foreign companies generally are not subject to uniform accounting,
auditing and financial reporting standards, practices and requirements
comparable to those applicable to U.S. companies. In addition, certain costs
attributable to foreign investing, such as custody charges, are higher than
those attributable to domestic investing. Securities of some foreign companies
are less liquid and their prices may be more volatile than securities of
comparable domestic companies. The Government Income and Strategic Income Funds'
and the Portfolio's interest and dividends from foreign issuers may be subject
to non-U.S. withholding taxes, thereby reducing their net investment income.
 
With respect to some foreign countries, there is the increased possibility of
expropriation or confiscatory taxation, limitations on the removal of funds or
other assets of the Government Income Fund, the Strategic Income Fund and the
Portfolio, political or social instability, or diplomatic developments which
could affect the investments of the Government Income Fund, the Strategic Income
Fund and the Portfolio in those countries. Moreover, individual foreign
economies may differ favorably or unfavorably from the U.S. economy in such
respects as growth of gross national product, rate of inflation, rate of savings
and capital reinvestment, resource self-sufficiency and balance of payments
positions.
 
CURRENCY RISK. Since the Government Income Fund, the Strategic Income Fund and
the Portfolio normally invest substantially in securities denominated in
currencies other than the U.S. dollar, and because they may hold foreign
currencies, they will be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rates between such currencies and the
U.S. dollar. Changes in currency exchange rates will influence the value of the
Funds' shares, and also may affect the value of dividends and interest earned by
the Funds and gains and losses realized by the Funds. Currencies generally are
evaluated on the basis of fundamental economic criteria (e.g., relative
inflation and interest rate levels and trends, growth rate forecasts, balance of
payments status and economic policies) as well as technical and political data.
The exchange rates between the U.S. dollar and other currencies are determined
by supply and demand in the currency exchange markets, the international balance
of payments, governmental intervention, speculation and other economic and
political conditions. If the currency in which a security is denominated
appreciates against the U.S. dollar, the dollar value of the security will
increase. Conversely, a decline in the exchange rate of the currency would
adversely affect the value of the security expressed in U.S. dollars.

                             GT GLOBAL INCOME FUNDS
 
In addition, many of the currencies in emerging market countries have
experienced steady devaluations relative to the U.S. dollar and major
devaluations have historically occurred in certain countries.
 
INVESTING IN EMERGING MARKETS. Because of the special risks associated with
investing in emerging markets, an investment in the Strategic Income Fund and
the Portfolio should be considered speculative. Investors are strongly advised
to consider carefully the special risks involved in emerging markets, which are
in addition to the usual risks of investing in developed foreign markets around
the world.
 
Investing in emerging markets involves risks relating to potential political and
economic instability within such markets and the risks of expropriation,
nationalization, confiscation of assets and property or the imposition of
restrictions on foreign investment and on repatriation of capital invested. In
the event of such expropriation, nationalization or other confiscation in any
emerging market, the Strategic Income Fund or the Portfolio could lose its
entire investment in that market.
 
Many emerging market countries have experienced substantial, and in some periods
extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have negative
effects on the economies and securities markets of certain emerging market
countries.
 
Economies in emerging markets generally are dependent heavily upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values and other protectionist measures imposed or negotiated by the countries
with which they trade. These economies also have been and may continue to be
affected adversely by economic conditions in the countries in which they trade.
 
The securities markets of emerging countries are substantially smaller, less
developed, less liquid and more volatile than the securities markets of the
United States and other more developed countries. Disclosure and regulatory
standards in many respects are less stringent than in the United States and
other major markets. There also may be a lower level of monitoring and
regulation of emerging securities markets and the activities of investors in
such markets, and enforcement of existing regulations has been extremely
limited.
 
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States, particularly with respect to emerging markets. Such markets have
different settlement and clearance procedures. In certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the Strategic Income Fund or the Portfolio to make intended
securities purchases due to settlement problems could cause the Strategic Income
Fund or the Portfolio to forego attractive investment opportunities. Inability
to dispose of a portfolio security caused by settlement problems could result
either in losses to the Strategic Income Fund or the Portfolio due to subsequent
declines in value of the portfolio security or, if the Strategic Income Fund or
the Portfolio has entered into a contract to sell the security, could result in
possible liability to the purchaser.
 
The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading of securities may cease or may be
substantially curtailed and prices for the Strategic Income Fund's or the
Portfolio's portfolio securities in such markets may not be readily available.
Section 22(e) of the 1940 Act permits a registered investment company to suspend
redemption of its shares for any period during which an emergency exists, as
determined by the SEC. Accordingly, when the Strategic Income Fund or the
Portfolio believes that appropriate circumstances warrant, it will promptly
apply to the SEC for a determination that an emergency exists within the meaning
of Section 22(e) of the 1940 Act. During the period commencing from the
Strategic Income Fund's or the Portfolio's identification of such conditions
until the date of SEC action, the portfolio securities of the Strategic Income
Fund or the Portfolio in the affected markets will be valued at fair value as
determined in good faith by or under the direction of the Company's Board of
Directors or the Portfolio's Board of Trustees.
 
MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. The yield characteristics of
mortgage-backed and asset-backed securities differ from those of traditional
bonds. Among the major differences are that interest and principal payments are
made more frequently (usually monthly) and that principal may be prepaid at any
time because the underlying mortgage loans or other assets generally
 
                               Prospectus Page 23
<PAGE>
                             GT GLOBAL INCOME FUNDS
may be prepaid at any time. Generally, prepayments on fixed-rate mortgage loans
will increase during a period of falling interest rates and decrease during a
period of rising interest rates. Mortgage-backed and asset-backed securities may
also decrease in value as a result of increasing market interest rates and,
because of prepayments, may benefit less than other bonds from declining
interest rates. Reinvestments of prepayments may occur at lower interest rates
than the original investment, thus adversely affecting the yield of the
Government Income Fund or the Strategic Income Fund. Actual prepayment
experience may cause the yield of a mortgage-backed security to differ from what
was assumed when the Fund purchased the security. The market for privately
issued mortgage-backed and asset-backed securities is smaller and less liquid
than the market for U.S. government mortgage-backed securities.
 
LOAN PARTICIPATIONS AND ASSIGNMENTS. The Strategic Income Fund and the Portfolio
may have difficulty disposing of Assignments and Participations. The liquidity
of such securities is limited and, the Fund and the Portfolio anticipate 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 and the Portfolio's ability to
dispose of particular Assignments or Participations when necessary to meet the
Fund's and/or the Portfolio's liquidity needs or in response to a specific
economic event, such as a deterioration in the creditworthiness of the borrower.
The lack of a liquid secondary market for Assignments and Participations also
may make it more difficult for the Fund and/or the Portfolio to assign a value
to those securities for purposes of valuing the Fund's or the Portfolio's
portfolio and calculating its net asset value.
 
SOVEREIGN DEBT. The Strategic Income Fund and the Portfolio may invest in
sovereign debt securities of emerging market governments, including Brady Bonds.
Investments in such securities involve special risks. The issuer of the debt or
the governmental authorities that control the repayment of the debt may be
unable or unwilling to repay principal or interest when due in accordance with
the terms of such debt. Periods of economic uncertainty may result in the
volatility of market prices of sovereign debt obligations and in turn a Fund's
net asset value, to a greater extent than the volatility inherent in domestic
fixed income securities.
 
A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Emerging market governments could default on
their sovereign debt. Such sovereign debtors also may be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
abroad to reduce principal and interest arrearages on their debt. The commitment
on the part of these governments, agencies and others to make such disbursements
may be conditioned on a sovereign debtor's implementation of economic reforms
and/or economic performance and the timely service of such debtor's obligations.
Failure to implement such reforms, achieve such levels of economic performance
or repay principal or interest when due, may result in the cancellation of such
third parties' commitments to lend funds to the sovereign debtor, which may
further impair such debtor's ability or willingness to timely service its debts.
 
The occurrence of political, social or diplomatic changes in one or more of the
countries issuing sovereign debt could adversely affect the Fund's or the
Portfolio's investments. Emerging markets are faced with social and political
issues and some of them have experienced high rates of inflation in recent years
and have extensive internal debt. Among other effects, high inflation and
internal debt service requirements may adversely affect the cost and
availability of future domestic sovereign borrowing to finance governmental
programs, and may have other adverse social, political and economic
consequences. Political changes or a deterioration of a country's domestic
economy or balance of trade may affect the willingness of countries to service
their sovereign debt. Although the Manager intends to manage the Strategic
Income Fund and the Portfolio in a manner that will minimize the exposure to
such risks, there can be no assurance that adverse political changes will not
cause the Fund or the Portfolio to suffer a loss of interest or principal on any
of its holdings.
 
In recent years, some of the emerging market countries in which the Strategic
Income Fund and the Portfolio expect 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.
 
                               Prospectus Page 24
<PAGE>
                             GT GLOBAL INCOME FUNDS
These difficulties have also led to agreements to restructure external debt
obligations -- in particular, commercial bank loans, typically by rescheduling
principal payments, reducing interest rates and extending new credits to finance
interest payments on existing debt. In the future, holders of emerging market
sovereign debt securities may be requested to participate in similar
rescheduling of such debt. Certain emerging market countries are among the
largest debtors to commercial banks and foreign governments. Currently, Brazil,
Mexico and Argentina are the largest debtors among developing countries. At
times certain emerging market countries have declared moratoria on the payment
of principal and interest on external debt; such a moratorium is currently in
effect in certain emerging market countries. There is no bankruptcy proceeding
by which a creditor may collect in whole or in part sovereign debt on which an
emerging market government has defaulted.
 
The ability of emerging market governments to make timely payments on their
sovereign debt securities is likely to be influenced strongly by a country's
balance of trade and its access to trade and other international credits. A
country whose exports are concentrated in a few commodities could be vulnerable
to a decline in the international prices of one or more of such commodities.
Increased protectionism on the part of a country's trading partners could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any. To the extent that a country receives payment for its
exports in currencies other than hard currencies, its ability to make hard
currency payments could be affected.
 
Investors should also be aware that certain sovereign debt instruments in which
the Strategic Income Fund and the Portfolio may invest involve great risk. As
noted above, sovereign debt obligations issued by emerging market governments
generally are deemed to be the equivalent in terms of quality to securities
rated below investment grade by Moody's and S&P. Such securities are regarded as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligations and involve
major risk exposure to adverse conditions. Some of such securities, with respect
to which the issuer currently may not be paying interest or may be in payment
default, may be comparable to securities rated D by S&P or C by Moody's. The
Strategic Income Fund and the Portfolio may have difficulty disposing of and
valuing certain sovereign debt obligations because there may be a limited
trading market for such securities. Because there is no liquid secondary market
for many of these securities, the Strategic Income Fund and the Portfolio
anticipate that such securities could be sold only to a limited number of
dealers or institutional investors.
 
LOWER QUALITY DEBT SECURITIES. Under normal market conditions the Strategic
Income Fund may invest up to 50% of its total assets in debt securities rated
below investment grade, and up to 100% of the Portfolio's total assets will be
so invested. Such investments involve a high degree of risk.
 
Debt rated Baa by Moody's is considered by Moody's to have speculative
characteristics. Debt rated BB, B, CCC, CC or C by S&P and debt rated Ba, B,
Caa, Ca or C by Moody's is regarded, on balance, as predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such lower quality debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions. Debt rated C
by Moody's or S&P is the lowest quality debt that is not in default as to
principal or interest and such issues so rated can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Lower
quality debt securities are also generally considered to be subject to greater
risk than higher quality securities with regard to a deterioration of general
economic conditions. These securities are the equivalent of high yield, high
risk bonds, commonly known as "junk bonds." As noted above, the Strategic Income
Fund and the Portfolio may invest in debt securities rated below C, which are in
default as to principal and/ or interest.
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit quality in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates. See
"Appendix A" for a discussion of Moody's and S&P's ratings.
 
The market values of lower quality debt securities tend to reflect individual
developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in
 
                               Prospectus Page 25
<PAGE>
                             GT GLOBAL INCOME FUNDS
the general level of interest rates. In addition, lower quality debt securities
tend to be more sensitive to economic conditions and generally have more
volatile prices than higher quality securities. Issuers of lower quality
securities are often highly leveraged and may not have available to them more
traditional methods of financing. For example, during an economic downturn or a
sustained period of rising interest rates, highly leveraged issuers of lower
quality securities may experience financial stress. During such periods, such
issuers may not have sufficient revenues to meet their interest payment
obligations. The issuer's ability to service its debt obligations may also be
adversely affected by specific developments affecting the issuer, such as the
issuer's inability to meet specific projected business forecasts or the
unavailability of additional financing. The risk of loss due to default by the
issuer is significantly greater for the holders of lower quality securities
because such securities are generally unsecured and may be subordinated to the
claims of other creditors of the issuer.
 
Lower quality debt securities of corporate issuers frequently have call or
buy-back features which would permit an issuer to call or repurchase the
security from the Strategic Income Fund or the Portfolio. If an issuer exercises
these provisions in a declining interest rate market, the Strategic Income Fund
or the Portfolio may have to replace the security with a lower yielding
security, resulting in a decreased return for investors. In addition, the
Strategic Income Fund and the Portfolio may have difficulty disposing of lower
quality securities because there may be a thin trading market for such
securities. There may be no established retail secondary market for many of
these securities, and the Strategic Income Fund and the Portfolio anticipate
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 Strategic Income Fund and the Portfolio to obtain accurate
market quotations for purposes of valuing the securities in the portfolios of
the Strategic Income Fund and the Portfolio. Adverse publicity and investor
perceptions, whether or not based on fundamental analysis, may also decrease the
values and liquidity of lower quality securities, especially in a thinly traded
market. The Strategic Income Fund and the Portfolio also may acquire lower
quality debt securities during an initial underwriting or may acquire lower
quality debt securities which are sold without registration under applicable
securities laws. Such securities involve special considerations and risks.
 
Factors having an adverse effect on the market value of lower rated securities
or their equivalents purchased by the Strategic Income Fund and the Portfolio
will adversely impact net asset value of the Strategic Income Fund and the High
Income Fund. See "Risk Factors" in the Statement of Additional Information. In
addition to the foregoing, such factors may include: (i) potential adverse
publicity; (ii) heightened sensitivity to general economic or political
conditions; and (iii) the likely adverse impact of a major economic recession.
The Strategic Income Fund and the Portfolio each also may incur additional
expenses to the extent it is required to seek recovery upon a default in the
payment of principal or interest on its portfolio holdings, and the Fund and the
Portfolio may have limited legal recourse in the event of a default. Debt
securities issued by governments in emerging markets can differ from debt
obligations issued by private entities in that remedies from defaults generally
must be pursued in the courts of the defaulting government, and legal recourse
is therefore somewhat diminished. Political conditions, in terms of a
government's willingness to meet the terms of its debt obligations, also are of
considerable significance. There can be no assurance that the holders of
commercial bank debt may not contest payments to the holders of debt securities
issued by governments in emerging markets in the event of default by the
governments under commercial bank loan agreements.
 
As of October 31, 1997, the Strategic Income Fund and the Portfolio had 89.27%
and 86.59%, respectively, of their total net assets in debt securities that
received a rating from Moody's and 4.00% and 10.29%, respectively, of their
total net assets in debt securities that were not so rated. In addition, the
Strategic Income Fund and the Portfolio had 6.73% and 3.12%, respectively, of
their total net assets in cash and net receivables. The Strategic Income Fund
had the following percentages of its total net assets invested in rated

vary and should not be considered representative of the future portfolio
composition of the Strategic Income Fund or the Portfolio.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Although each Fund and the
Portfolio is authorized to enter into options, futures and forward currency
transactions, the Funds and the Portfolio might not enter into any such
transactions. In addition, issuers in emerging markets typically are subject to
a greater degree of change in earnings and business prospects than issuers in
developed countries. Options, futures and foreign currency transactions involve
certain risks, which include: (1) dependence on the Manager's ability to predict
movements in the prices of individual securities, fluctuations in the general
securities markets or in the appropriate market sector and movements in interest
rates and currency markets; (2) imperfect correlation, or even no correlation,
between movements in the price of options, forward contracts, futures contracts
or options thereon and movements in the price of the currency or security hedged
or used for cover; (3) the fact that skills and techniques needed to trade
options, futures contracts and options thereon or to use forward currency
contracts are different from those needed to select the securities in which a
Fund or Portfolio invests; (4) lack of assurance that a liquid secondary market
will exist for any particular option, futures contract or option thereon at any
particular time; (5) the possible loss of principal under certain conditions;
and (6) the possible inability of a Fund or Portfolio to purchase or sell a
portfolio security at a time when it would otherwise be favorable for it to do
so, or the possible need for a Fund or Portfolio to sell a security at a
disadvantageous time, due to the need for the Fund or Portfolio to maintain
"cover" or to set aside securities in connection with hedging transactions.
 
ILLIQUID SECURITIES. The Government Income Fund may invest up to 10% of its
total assets, and the Strategic Income Fund and the Portfolio up to 15% of their
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.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
GENERAL. Shares of a Fund may be purchased through Financial Institutions, some
of which may charge the investor a transaction fee. That fee will be in addition
to the sales charge payable by the investor, with respect to Class A shares.
Some of these Financial Institutions (or their designees) may be authorized to
accept purchase orders on behalf of the Fund. All purchase orders will be
executed at the public offering price next determined after the purchase order
is received, which includes any applicable sales charge for Class A shares.
Orders received by the Transfer Agent before the close of regular trading on the
New York Stock Exchange ("NYSE") (currently 4:00 p.m. Eastern Time, unless
weather, equipment failure or other factors contribute to an earlier closing
time) on any Business Day will be executed at the public offering price for the
applicable class of shares determined that day. Orders received by authorized
institutions (or their designees) before the close of regular trading on the
NYSE on a Business Day will be deemed to have been received by a Fund on such
day and will be effected that day, provided that such orders are transmitted to
the Transfer Agent prior to the time set for receipt of such orders. A "Business
Day" is any day Monday through Friday on which the NYSE is open for business.
Financial Institutions are responsible for forwarding the investor's order to
the Transfer Agent so that it will be received prior to the required time.
 
The minimum initial investment is $500 ($100 for IRAs and $25 for custodial
accounts under Section 403(b)(7) of the Internal Revenue Code of 1986, as
amended (the "Code"), and other tax-qualified employer-sponsored retirement
accounts, if made under a systematic investment plan providing for monthly or
quarterly payments of at least that amount). The minimum for additional
purchases is $100 ($25 for IRAs, Code Section 403(b)(7) custodial accounts and
other tax-qualified employer-sponsored retirement accounts, as mentioned above).
THE FUNDS AND GT GLOBAL RESERVE THE RIGHT TO REJECT ANY PURCHASE ORDER. In
particular, the Funds 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 A 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 a 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 Funds 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
Funds. 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 Funds. 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 INCOME FUNDS
 
CERTIFICATES. Physical certificates representing a Fund's shares will not be
issued unless a written request is submitted to the Transfer Agent. Shares of a
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 FUNDS AND GT
GLOBAL RECOMMEND THAT SHAREHOLDERS DO NOT REQUEST ISSUANCE OF CERTIFICATES.
 
DIFFERENCES BETWEEN THE CLASSES. The primary difference between the classes of
each 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 a Fund represent interests in the same Fund and have the same rights, except
that each class bears the separate expenses of its 12b-1 distribution plan and
has exclusive voting rights with respect to such plan, each class can experience
other minor expense differences and, in addition to different sales charges,
each class has a separate exchange privilege.
 
The decision as to which class of shares is more beneficial to an investor
depends on the amount invested, the intended length of time the investment is
held and the investor's personal situation. Large investments may qualify for a
reduced Class A sales charge. Investors in Class B shares have 100% of the
purchase invested immediately. Consult your financial adviser. Financial
Institutions may receive different levels of compensation for selling a
particular class of shares.
 
ADVISOR CLASS SHARES. Advisor Class shares are offered through a separate
prospectus to (a) trustees or other fiduciaries purchasing shares for employee
benefit plans that are sponsored by organizations that have at least 1,000
employees; (b) any account with assets of at least $10,000 if (i) a financial
planner, trust company, bank trust department or registered investment adviser
has investment discretion over the account and (ii) the account holder pays such
person as compensation for its advice and other services an annual fee of at
least .50% of the assets in the account; (c) any account with assets of at least
$10,000 if (i) the account is established under a "wrap fee" program and (ii)
the account holder pays the sponsor of the program an annual fee of at least
 .50% of the assets in the account; (d) accounts advised by one of the companies
composing or affiliated with Liechtenstein Global Trust; (e) any of those
companies; and (f) GT Global New Dimension Fund.
 
                           PURCHASING CLASS A SHARES
 
Each 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
determined in accordance with the following schedule.

- ------------------
*   GT Global will pay the following commissions to broker/ dealers that
    initiate and are responsible for purchases by any single purchaser of Class
    A shares of $500,000 or more in the aggregate: 1.00% of the purchase amount
    up to $3 million, plus 0.50% on the excess over $3 million. For purposes of
    determining the appropriate commission to be paid in connection with the
    transaction, GT Global will combine purchases made by a broker/dealer on
    behalf of a single client so that the broker/dealer's commission, as
    outlined above, will be based on the aggregate amount of such client's share
    purchases over a rolling twelve month period from the date of the
    transaction.
 
+   All shares purchased without a sales charge based on the aggregate purchase
    amount equalling at least $500,000 will be subject to a contingent deferred
    sales charge for the first year after their purchase equal to 1% of the
    lower of the original purchase price or the net asset value of such shares
    at the time of redemption. See "Contingent Deferred Sales Charge -- Class A
    Shares."
 
From time to time, GT Global may reallow to broker/ dealers the full amount of
the sales charge or may pay out additional amounts to broker/dealers who sell
Class A shares. In some instances, GT Global may offer these reallowances or
additional payments only to broker/dealers that have sold or may sell
significant amounts of Class A shares. To the extent that GT Global reallows the
full amount of the sales charge to broker/dealers, such broker/dealers may be
deemed to be underwriters under the Securities Act of 1933, as amended.
Commissions also may be paid to broker/dealers and other financial institutions
that initiate purchases of at least $500,000 made pursuant to sales charge
waivers (i) and (vii) described below under "Sales Charge Waivers -- Class A
Shares."

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

including plans under Code Section 401(k), and medical, life and disability
insurance trusts) other than a plan described in "(a)" above; and
 
(c) Individual purchases by a trustee or other fiduciary purchasing shares
concurrently for two or more employee benefit plans of a single employer or of
employers affiliated with each other (again excluding an employee benefit plan
described in "(a)" above).

(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

Global regarding such accounts.
 
(xii) Certain former AMA Investment Advisers' shareholders who became

REINSTATEMENT PRIVILEGE. Shareholders who redeem their Class A shares in a Fund
have a one-

<PAGE>
                             GT GLOBAL INCOME FUNDS
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 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 Funds 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 the 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 FUNDS AND OTHER GT GLOBAL MUTUAL FUND (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 Funds and the Class A shares of other GT Global Mutual Funds (other than
shares of GT Global Dollar Fund) in the following thirteen months. The LOI is
included as part of the Account Application located at the end of this
Prospectus. The sales charge applicable to that aggregate amount then becomes
the applicable sales charge on all purchases made concurrently with the
execution of the LOI and in the thirteen months following that execution. If an
investor executes an LOI within 90 days of a prior purchase of GT Global Mutual
Fund Class A shares (other than shares of GT Global Dollar Fund), the prior
purchase may be included under the LOI and an appropriate adjustment, if any,
with respect to the sales charges paid by the investor in connection with the
prior purchase will be made, based on the then-current net asset value(s) of the
pertinent Fund(s).
 
If at the end of the thirteen month period covered by the LOI the total amount
of purchases does not equal the amount indicated, the investor will be required
to pay the difference between the sales charges paid at the reduced rate and the
sales charges applicable to the purchases actually made. Shares having a value
equal to 5% of the amount specified in the LOI will be held in escrow during the
thirteen month period (while remaining registered in the investor's name) and
are subject to redemption to assure any necessary payment to GT Global of a
higher applicable sales charge.
 
For purposes of an LOI, any registered investment adviser, trust company or bank
trust department which exercises investment discretion and which intends within
thirteen months to invest $500,000 or more, can be treated as a single
purchaser, provided further that such entity places all purchase and redemption
orders. Such entities should be prepared to establish their qualification for
such treatment. THE FOREGOING LOI WILL APPLY ONLY TO CLASS A SHARES OF THE FUNDS
AND SHARES OF ANY GT GLOBAL MUTUAL FUND THAT OFFERS A SINGLE CLASS OF SHARES
(OTHER THAN GT GLOBAL DOLLAR FUND).
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS A SHARES. Purchases of Class A shares
of $500,000 or more may be made without a sales charge. If a shareholder within
one year after the date of purchase redeems any Class A shares that were
purchased without a sales charge by reason of a purchase of $500,000 or more, a
contingent deferred sales charge of 1% of the lower of the original purchase
price or the net asset value of such shares at the time of redemption will be
charged. Class A shares will not be subject to the contingent deferred sales
charge to the extent that the value of such shares represents (1) reinvestment
of dividends or other distributions or (2) shares redeemed more than one year
after their purchase. Such shares purchased without a sales charge may 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

<PAGE>
                             GT GLOBAL INCOME FUNDS
deferred sales charge described above will apply to the redemption of the shares
acquired through an exchange. 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. The waivers set forth under "Contingent
Deferred Sales Charge Waivers" 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
 
Each 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 of the Fund will be deemed to have occurred at the time of the
initial purchase of the Floating Rate Fund's common stock.
 
For federal income tax purposes, the amount of the contingent deferred sales
charge will reduce the gain or increase the loss, as the case may be, realized
on a redemption. The amount of any contingent deferred sales charge will be paid
to GT Global.
 
                              CONTINGENT DEFERRED
                              SALES CHARGE WAIVERS
 
The contingent deferred sales charge will be waived for: (1) exchanges, as
described below; (2) redemptions in connection with each Fund's systematic
withdrawal plan not in excess of 12% of the value of the account annually; (3)
total or partial redemptions made within one year following the death or
disability of a shareholder; (4) minimum required distributions made in
connection with a GT Global IRA, Keogh Plan or custodial account under Section
403(b) of the Code or other retirement plan following attainment of age 70 1/2;
(5) total or partial redemptions resulting from a distribution following
retirement in the case of a tax-qualified employer-sponsored retirement plan;
(6) when a redemption results from a tax-free return of an excess contribution
pursuant to Section 408(d)(4) or (5) of the Code or from the death or disability
of the employee; (7) a one-time reinvestment in Class B shares of a Fund within
180 days of a prior redemption; (8) redemptions pursuant to a Fund's right to
liquidate a shareholder's account involuntarily; (9) redemptions pursuant to
distributions from a tax-qualified employer-sponsored retirement plan, which is
invested in GT Global Mutual Funds, which are permitted to be made without
penalty pursuant to the Code (other than tax-free rollovers or transfers of
asset) and the proceeds of which are reinvested in GT Global Mutual Funds; (10)
redemptions made in connection with participant-directed exchanges between
options in an employer-sponsored benefit plan; (11) redemptions made for the
purpose of providing cash to fund a loan to a participant in a tax-qualified
retirement plan; (12) redemptions made in connection with a distribution from
any retirement plan or account that is permitted in accordance with the
provisions of Section 72(t)(2) of the Code, and the regulations promulgated
thereunder; (13) redemptions made in connection with a distribution from any
retirement plan or account that involves the return of an excess deferral amount
pursuant to Section 401(k)(8) or Section 402(g)(2) of the Code or the return of
excess aggregate contributions pursuant to Section 401(m)(6) of the Code; (14)
redemptions made in connection with a distribution from a qualified
profit-sharing or stock bonus plan described in Section 401(k) of the Code to a
participant or beneficiary under Section 401(k)(2)(B)(IV) of the Code upon
hardship of the covered employee (determined pursuant to Treasury Regulation
Section 1.401(k)-1(d)(2)); and (15) redemptions made by or for the benefit of
certain states, counties or cities, or any instrumentalities, departments or
authorities thereof where such entities are prohibited or limited by applicable
law from paying a sales charge or commission.
 
                             PROGRAMS APPLICABLE TO
                       CLASS A SHARES AND CLASS B SHARES
 
AUTOMATIC INVESTMENT PLAN. Investors may purchase either Class A or Class B
shares of a Fund through the GT Global Automatic Investment Plan. Under this
Plan, an amount specified by the shareholder of $100 or more (or $25 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 a Fund in cash. A sales charge will be
applied to each automatic monthly purchase of Class A Fund shares in an amount
determined in accordance with the Right of Accumulation privilege described
above. To participate in the Automatic Investment Plan, investors should
complete the appropriate portion of the Supplemental Application provided at the
end of this Prospectus. Investors should contact their Financial Institution or
GT Global for more information.
 
DOLLAR COST AVERAGING PROGRAM. Investors may purchase either Class A or Class B
shares of a 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 a Fund's net asset value is relatively low and fewer
shares when a 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
 
                               Prospectus Page 33
<PAGE>
                             GT GLOBAL INCOME FUNDS
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.
 
A participant in the GT Global Dollar Cost Averaging Program first designates
the size of his or her monthly investment in a 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 Fund 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 Exchanges." If shares of the
GT Global Mutual Fund(s) in a shareholder's Personal Portfolio have appreciated
during a rebalancing period, the Program will result in shares of GT Global
Mutual Fund(s) that have appreciated most during the period being exchanged for
shares of GT Global Mutual Fund(s) that have appreciated least. SUCH EXCHANGES
ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS
THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends, Other
Distributions and Federal Income Taxation." Participation in the Program does
not assure that a shareholder will profit from purchases under the Program nor
does it prevent or lessen losses in a declining market.
 
The Program will automatically rebalance the shareholder's Personal Portfolio on
the 28th day of the last month of the period chosen (or the immediately
preceding business day if the 28th is not a business day), subject to any
limitations below. The Program will not execute an exchange if the variance in a
shareholder's Personal Portfolio for a particular Fund would be 2% or less. In
predesignating percentages, shareholders must use whole percentages and totals
must equal 100%. Shareholders participating in the Program may not request
issuance of physical certificates representing a Fund's shares. Exchanges made
under the Program are not subject to the four free exchanges per year
limitation. The Funds and GT Global reserve the right to modify, suspend, or
terminate the Program at any time on 60 days' prior written notice to
shareholders. A request to participate in the Program must be received in good
order at least five business days prior to the next rebalancing date. Once a
shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which Funds or
what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, Letter of Intent
and Dollar Cost Averaging programs. Certain Financial Institutions may charge a
fee for establishing accounts relating to the Program. Investors should contact
their Financial Institution or GT Global for more information.

                             HOW TO MAKE EXCHANGES
 
- --------------------------------------------------------------------------------
 
Shares of a Fund may be exchanged for shares of the same class of any other GT
Global Mutual Fund, based on their respective net asset values without
imposition of any sales charges, provided that the registration remains
identical. EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'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 Funds, 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
   -- GTGLOBAL CONSUMER PRODUCTS AND
       SERVICES FUND
   -- GT GLOBAL DOLLAR FUND
   -- GT GLOBAL DEVELOPING MARKETS FUND
   -- GT GLOBAL EUROPE GROWTH FUND
   -- GT GLOBAL FINANCIAL SERVICES FUND
   -- GT GLOBAL GROWTH & INCOME FUND
   -- GT GLOBAL HEALTH CARE FUND
   -- GT GLOBAL INFRASTRUCTURE FUND
   -- GT GLOBAL INTERNATIONAL GROWTH FUND
   -- GT GLOBAL JAPAN GROWTH FUND
   -- GT GLOBAL LATIN AMERICA GROWTH FUND
   -- GT GLOBAL NATURAL RESOURCES FUND
   -- GT GLOBAL NEW DIMENSION FUND
   -- GT GLOBAL NEW PACIFIC GROWTH FUND
   -- GT GLOBAL TELECOMMUNICATIONS FUND
   -- GT GLOBAL WORLDWIDE GROWTH FUND
 
Up to four exchanges each year per Fund may be made without charge. A $7.50
service charge will be imposed on each subsequent exchange. If a shareholder
does not surrender all of his or her shares in an exchange, the remaining
balance in the shareholder's account after the exchange must be at least $500.
Exchange requests received in good order by the Transfer Agent before the close
of regular trading on the NYSE on any Business Day will be processed at the net
asset value calculated on that day. The terms of the exchange offer may be
modified at any time, on 60 days' prior written notice.
 
An investor interested in making an exchange should contact his or her Financial
Institution or the Transfer Agent to request the prospectus of the other GT
Global Mutual Fund(s) being considered. Certain Financial Institutions may
charge a fee for handling exchanges.
 
EXCHANGES BY TELEPHONE. A shareholder may give exchange instructions to the
shareholder's Financial Institution or to 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 have previously been deposited. Shareholders
automatically have telephone privileges to authorize exchanges. The Funds, 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 Funds employ 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
 
- --------------------------------------------------------------------------------
 
Shares of each Fund 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 that sell shares of a 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 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 a 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.

<PAGE>
                             GT GLOBAL INCOME FUNDS
Shareholders who hold certificates for shares may not redeem by telephone.
REDEMPTION REQUESTS MAY NOT BE MADE BY TELEPHONE FOR FIFTEEN DAYS FOLLOWING ANY
CHANGE OF THE SHAREHOLDER'S ADDRESS OF RECORD.
 
Shareholders automatically have telephone privileges to authorize redemptions.
The Funds, GT Global and the Transfer Agent will not be liable for any loss or
damage for acting in good faith upon instructions received by telephone and
reasonably believed to be genuine. The Fund employs reasonable procedures to
confirm that instructions communicated by telephone are genuine prior to acting
upon instructions received by telephone, including requiring some form of
personal identification, providing written confirmation of such transactions,
and/or tape recording of telephone instructions.
 
REDEMPTIONS BY MAIL. Redemption requests should be mailed directly to the
Transfer Agent at the appropriate address provided in the Shareholder Account
Manual. As discussed above, requests for payment of redemption proceeds to a
party other than the shareholder of record and/or requests that redemption
proceeds be mailed to an address other than the shareholder's address of record
require a signature guarantee. In addition, if the shareholder's address of
record has been changed within the preceding fifteen days, a signature guarantee
is required. Redemptions of shares for which certificates have been issued must
be accompanied by properly endorsed share certificates.
 
SYSTEMATIC WITHDRAWAL PLAN. Shareholders owning shares with a value of $10,000
or more may participate in the GT Global Systematic Withdrawal Plan. A
participating shareholder will receive proceeds from monthly, quarterly or
annual redemptions of Fund shares with respect to either Class A or Class B
shares. No contingent deferred sales charge will be imposed on redemptions made
under the Systematic Withdrawal Plan. The minimum withdrawal amount is $100. The
amount or percentage a participating shareholder specifies to be redeemed may
not, on an annualized basis, exceed 12% of the value of the account, as of the
time the shareholder elects to participate in the Systematic Withdrawal Plan. To
participate in the Systematic Withdrawal Plan, investors should complete the
appropriate portion of the Supplemental Application provided at the end of this
Prospectus. Investors should contact their Financial Institution or the Transfer
Agent for more information. With respect to Class A shares, participation in the
Systematic Withdrawal Plan concurrent with purchases of Class A shares of the
Fund may be disadvantageous to investors because of the sales charges involved
and possible tax implications, and therefore is discouraged. In addition,
shareholders who participate in the Systematic Withdrawal Plan should not elect
to reinvest dividends or other distributions in additional Fund shares.
Systematic withdrawal plans offered by Financial Institutions may have different
features. Accordingly, shareholders should contact their Financial Institution
for more details.
 
CHECKWRITING -- GOVERNMENT INCOME FUND -- CLASS A SHARES. Class A shareholders
of Government Income Fund may redeem their Government Income Fund shares by
writing checks, a supply of which may be obtained through the Transfer Agent,
against their Government Income Fund accounts. The minimum check amount is $300.
When the check is presented to the Transfer Agent for payment, the Transfer
Agent will cause the Government Income Fund to redeem a sufficient number of
Class A shares to cover the amount of the check. This procedure enables the
shareholder to continue receiving dividends on those shares until such time as
the check is presented to the Transfer Agent for payment. Cancelled checks are
not returned. However, such shareholders may obtain photocopies of their
cancelled checks upon request. If a shareholder does not own sufficient Class A
shares to cover a check, the check will be returned to the payee marked
"nonsufficient funds." Checks written in amounts less than $300 also will be
returned. The Government Income Fund and the Transfer Agent reserve the right to
terminate or modify the checkwriting service at any time or to impose a service
charge in connection with it.
 
Because the aggregate amount of Government Income Fund Class A shares owned by a
shareholder is likely to change each day, shareholders should not attempt to
redeem all of their Government Income Fund shares held in their accounts by
using the check redemption procedure. Charges may be imposed for specially
imprinted checks, business checks, copies of cancelled checks, stop payment
orders, checks returned "nonsufficient funds" and checks returned because they
are written for less than $300. These charges will be paid by redeeming
automatically an appropriate number of Government Income Fund Class A shares.
 
Shareholders of Government Income Fund Class A shares who are interested in
checkwriting should
 
                               Prospectus Page 37
<PAGE>
                             GT GLOBAL INCOME FUNDS
obtain the necessary forms by calling the Transfer Agent at the number provided
in the Shareholder Account Manual. Checkwriting generally is not available to
persons who hold Government Income Fund Class A shares in tax-deferred
retirement plan accounts.
 
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 Financial Institution or the Transfer Agent.
 
Except in extraordinary circumstances and as permitted under the 1940 Act,
payment for shares redeemed by telephone, or by mail will be made promptly after
receipt of a redemption request, if in good order, but not later than seven days
after the date the request is executed. Requests for redemption which are
subject to any special conditions or which specify a future or past effective
date cannot be accepted.
 
If the Transfer Agent is requested to redeem shares for which a 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.
 
A Fund may redeem the shares of any shareholder whose account is reduced to less
than $500 in net asset value through redemptions or other action by the
shareholder. Written notice will be given to the shareholder at least 60 days
prior to the date fixed for such redemption, during which time the shareholder
may increase his or her holdings to an aggregate amount of $500 or more (with a
minimum purchase of $100).

                             GT GLOBAL INCOME FUNDS
 
                         CALCULATION OF NET ASSET VALUE
 
- --------------------------------------------------------------------------------
 
Each Fund calculates its net asset value as of the close of normal 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. Each
Fund's net asset value per share is computed by determining the value of its
total assets (which, in the case of the High Income Fund, is the value of its
proportionate share of the total assets of the Portfolio) subtracting all of its
liabilities, and dividing the result by the total number of shares outstanding
at such time. Net asset value is determined separately for each class of shares
of each Fund.
 
Long-term debt obligations held by a Fund or the Portfolio are valued at the
mean of representative quoted bid and asked prices for such securities or, if
such prices are not available, at prices for securities of comparable maturity,
quality and type; however, when the Manager deems it appropriate, prices
obtained from a bond pricing service will be used. Short-term debt investments
are amortized to maturity based on their cost, adjusted for foreign exchange
translation and market fluctuations, provided such valuations represent fair
value. Equity securities are valued at the last sale price on the exchange or in
the OTC market in which such securities are primarily traded, as of the close of
business on the day the securities are being valued, or, lacking any sales, at
the last available bid price. When market quotations for futures and options
positions held by a Fund or the Portfolio 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 or the Portfolio's Board of
Trustees. Securities and other assets quoted in foreign currencies are valued in
U.S. dollars based on the prevailing exchange rates on that day.
 
Each Fund's or the Portfolio's portfolio securities, from time to time, may be
listed primarily on foreign exchanges or OTC dealer markets that may trade on
days when the NYSE is closed (such as Saturday). As a result, the net asset
value of a Fund may be significantly affected by such trading on days when
shareholders cannot purchase or redeem shares of that Fund.
 
The different service and distribution fees borne by each class of shares of
each Fund will result in different net asset values. The per share net asset
value of the Class B shares of a Fund generally will be lower than that of the
Class A shares of that Fund because of the higher service and distribution fees
borne by the Class B shares. The per share net asset value of the Advisor Class
shares of a Fund generally will be higher than that of the Class A and Class B
shares of that Fund because of the absence of any service and distribution fees
applicable to the Advisor Class shares. It is expected, however, that the net
asset value per share of the classes of a Fund 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. Each Fund declares and pays monthly dividends
from its net investment income, if any, which includes accrued interest, earned
discount (including both original issue and market discounts) and dividends less
applicable expenses. Each Fund also annually distributes substantially all of
its realized net capital gains and net gains from foreign currency transactions,
if any. Each 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 each 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 of a Fund will be lower than the per
share income dividends on Class A shares of that Fund 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 of a Fund will be lower than the
per share income dividends on the Advisor Class shares of that Fund 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 a Fund has the effect of reducing the
net asset value per share on the ex-dividend 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. Each Fund intends to continue to qualify for treatment as a regulated
investment company under the Code. In each taxable year that a 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. In the case of the High Income Fund, its
investment company taxable income and net capital gain consists of its
proportionate share of the Portfolio's net investment income, net gains from
certain foreign currency transactions and net short-term capital gain and net
capital gain. The Portfolio expects that it also will not be liable for any
federal income tax.
 
Dividends from a 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 the Fund's
 
                               Prospectus Page 41
<PAGE>
                             GT GLOBAL INCOME FUNDS
earnings and profits. Distributions of a Fund's net capital gain, when
designated as such, are taxable to its shareholders as long-term capital gains
regardless of how long they have held their Fund shares and whether paid in cash
or reinvested in additional shares.
 
Under the Taxpayer Relief Act of 1997, different maximum tax rates apply to a
noncorporate taxpayer's net capital gain depending on the taxpayer's holding
period and marginal rate of federal income tax -- generally, 28% for gain
recognized on securities held for more than one year but not more than 18 months
and 20% (10% for taxpayers in the 15% marginal tax bracket) for gain recognized
on securities held for more than 18 months. Pursuant to an Internal Revenue
Service notice, each 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.
 
Each 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.
 
Each 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 a
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 (including another Fund)
generally will have similar tax consequences. However, special tax rules apply
when a shareholder (1) disposes of Class A shares of a Fund through a redemption
or exchange within 90 days after purchase and (2) subsequently acquires Class A
shares of that Fund or 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 the shares were acquired, and that
amount will increase the adjusted basis of the shares subsequently acquired. In
addition, if shares of a Fund are purchased within 30 days before or after
redeeming other shares of that Fund (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 each 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 are therefore urged to consult their
tax advisers.

The Company's Board of Directors and the Portfolio's Board of Trustees have
overall responsibility for the operation of the Funds and the Portfolio,
respectively, and have approved contracts with various financial organizations
to provide, among other things, day to day management services required by the
Funds and the Portfolio. See "Directors, Trustees, and Executive Officers" in
the Statement of Additional Information for a complete description of the
Directors of each of the Funds and the Trustees of the Portfolio.
 
INVESTMENT MANAGEMENT AND ADMINISTRATION. Services provided by Chancellor LGT
Asset Management, Inc. (the "Manager") as the Government Income Fund's, the
Strategic Income Fund's and the Portfolio's investment manager and administrator
include, but are not limited to, determining the composition of the investment
portfolio of the Government Income Fund, the Strategic Income Fund and the
Portfolio and placing orders to buy, sell or hold particular securities. In
addition, the Manager provides the following administration services to the
Funds and the Portfolio: furnishing corporate officers and clerical staff;
providing office space, services and equipment; and supervising all matters
relating to the Government Income Fund's, the Strategic Income Fund's and the
Portfolio's operation.
 
The Government Income Fund and the Strategic Income Fund each pays the Manager
administration fees computed daily and payable monthly, based on their
respective average daily net assets, for such services at the annualized rate of
 .725% on the first $500 million, .70% on the next $1 billion, .675% on the next
$1 billion, and .65% on amounts thereafter. The High Income Fund pays
administration fees, directly to the Manager at the annualized rate of 0.25% of
the Fund's average daily net assets. In addition, the Fund bears its pro rata
portion of the investment management and administration fees paid by the
Portfolio to the Manager. The Portfolio pays such fees, based on the average
daily net assets of the Portfolio, directly to the Manager at the annualized
rate of .475% on the first $500 million, .45% on the next $1 billion, .425% on
the next $1 billion and .40% on amounts thereafter, plus 2% of the Portfolio's
total investment income as stated in the Portfolio's Statement of Operations,
calculated in accordance with generally accepted accounting principles, adjusted
daily for currency revaluations, on a marked to market basis, of the Portfolio's
assets; provided, however, that during any fiscal year this amount shall not
exceed 2% of the Portfolio's total investment income calculated in accordance
with generally accepted accounting principles. These rates are higher than those
paid by most mutual funds. Each Fund pays all expenses not assumed by the
Manager, GT Global or any other agents. The Manager and GT Global have
undertaken to limit the expenses of the Class A and Class B shares of the
Government Income Fund and the Strategic Income Fund (exclusive of brokerage
commissions, taxes, interest and extraordinary expenses) to the maximum annual
level of 1.85% and 2.50% of the average daily net assets of such Funds' Class A
and Class B shares, respectively. The Manager and GT Global have undertaken to
limit the expenses of the Class A and Class B shares of the High Income Fund
(and such Fund's pro-rata portion of the Portfolio's expenses) to the maximum
annual level of 2.25% and 2.85% of the average daily net assets of such Fund's
Class A and Class B shares, respectively. This undertaking may be changed or
eliminated in the future.
 
The Manager also serves as each Fund's pricing and accounting agent. For these
services the Manager receives a fee at an annual rate derived by applying 0.03%
to the first $5 billion of assets of GT Global Funds and 0.02% to the assets in
excess of $5 billion and allocating the result according to each Fund's average
daily net assets.
 
The Manager provides investment management and/or administration services to the
GT Global Funds. The Manager and its worldwide asset management affiliates have
provided investment management and/or administration services to institutional,
corporate and individual clients around the world since 1969. The U.S. offices
of the Manager are located at 50 California Street, 27th Floor, San Francisco,
CA 94111 and 1166 Avenue of the Americas, New York, NY 10036.
 
The Manager and its worldwide affiliates, including LGT Bank in Liechtenstein

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
investment management agreements under the Investment Company Act of 1940 (and,
therefore, a termination of such agreements), it is anticipated that the
approval of the Portfolio's Board of Trustees, 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 manage 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 the GT Global Funds. As of December 31, 1997, assets
entrusted to LGT totaled approximately $79 billion.
 
In addition to the investment resources of its San Francisco and New York
offices, the Manager draws upon the expertise, personnel, data and systems of
other offices of Liechtenstein Global Trust, including investment offices in
Frankfurt, Hong Kong, London, Singapore, Sydney, Tokyo and Toronto. In managing
the GT Global Funds, the Manager employs a team approach, taking advantage of
its investment resources around the world in seeking each Fund's investment
objective.

of the Government Income Fund, the Strategic Income Fund and the Portfolio are

In placing orders for the Government Income Fund's, Strategic Income Fund's and
the Portfolio's securities 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 for the Fund 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 Funds or the Portfolio 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 each Fund's Class A
and Class B shares. Like the Manager, GT Global is a subsidiary of Liechtenstein
Global Trust with offices at 50 California Street, 27th Floor, San Francisco, CA
94111. As distributor, GT Global collects the sales charges imposed on purchases
of Class A shares and any contingent deferred sales charges that may be imposed
on certain redemptions of Class A and 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." In addition, GT Global pays a commission equal to 4.00% of the amount
invested to broker/dealers who sell Class B shares. From time to time, GT Global
may pay commissions in excess of these amounts. Commissions are not paid on
exchanges or certain reinvestments in Class B shares. In addition, with respect
to both classes of shares, GT Global makes ongoing payments to broker/dealers
for distribution and service activities in accordance with the Rule 12b-1 plans
described below.
 
GT Global, at its own expense, may provide additional promotional incentives to
broker/dealers that sell shares of the Funds 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 brokers 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 each Fund's Class A
shares ("Class A Plan"), each Fund may pay GT Global a service fee at the
annualized rate of up to 0.25% of the average daily net assets of such Fund's
Class A shares for its expenditures incurred in servicing and maintaining
shareholder accounts, and may pay GT Global a distribution fee at the annualized
rate of up to 0.35% of the average daily net assets of the Fund's Class A
shares, less any amounts paid by the Fund as the aforementioned service fee for
its expenditures incurred in providing services as distributor. All expenses for
which GT Global is reimbursed under the Class A Plan will have been incurred
within one year of such reimbursement.
 
Pursuant to a separate plan of distribution adopted with respect to each Fund's
Class B shares ("Class B Plan"), each Fund may pay GT Global a service fee at
the annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class B shares for its expenditures incurred in servicing and maintaining
shareholder accounts, and may pay GT Global a distribution fee at the annualized
rate of up to 0.75% of the average daily net assets of the Fund's Class B shares
for its expenditures incurred in providing services as distributor. Expenses
incurred under the Class B Plan in excess of 1.00% annually may be carried
forward for reimbursement in subsequent years as long as that Plan continues in
effect. As of October 31, 1997, unreimbursed distribution expenses for the
Government Income Fund, Strategic Income Fund and High Income Fund amounted to
approximately $85,000, $313,000 and $347,000, respectively. Such amounts
represented approximately .07%, .14% and .12% of the net assets of the
Government Income Fund, Strategic Income Fund and High Income Fund,
respectively.
 
GT Global's service and distribution expenses covered by the Plans include the
payment of commissions; the cost of any additional
 
                               Prospectus Page 45
<PAGE>
                             GT GLOBAL INCOME FUNDS
compensation paid by GT Global to broker/dealers; the costs of printing and
mailing to prospective investors prospectuses and other materials relating to
the Funds; the costs of developing, printing, distributing and publishing
advertisements and other sales literature; and allocated costs relating to GT
Global's distribution activities, including, among other things, employee
salaries, bonuses and other overhead expenses. In addition, its expenses covered
by the Class B Plan include payment of initial sales commissions to broker/
dealers and interest on any unreimbursed amounts carried forward thereunder.
 
The Glass-Steagall Act and other applicable laws, among other things, generally
prohibit federally chartered or supervised banks from engaging in the business
of underwriting or distributing securities. Accordingly, GT Global intends to
engage banks (if at all) only to perform administrative and shareholder
servicing functions. Banks and broker/ dealer affiliates of banks also may
execute dealer agreements with GT Global for the purpose of selling shares of
the Fund. If a bank were prohibited from so acting, its shareholder clients
would be permitted to remain shareholders, and alternative means for continuing
the servicing of such shareholders would be sought. It is not expected that
shareholders would suffer any adverse financial consequences as a result of any
of these occurrences.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
CONFIRMATIONS AND REPORTS TO SHAREHOLDERS. Each time a transaction is made that
affects a shareholder's account in a Fund, the shareholder will receive from the
Transfer Agent a confirmation statement reflecting the transaction.
Confirmations for transactions effected pursuant to a Fund's Automatic
Investment Plan, Systematic Withdrawal Plan, and automatic dividend reinvestment
program may be provided quarterly. Shortly after the end of each Fund's fiscal
year on October 31 and fiscal half-year on April 30 of each year, shareholders
receive an annual and a semiannual report, respectively. In addition, the
federal income status of distributions made by a Fund to shareholders are
reported after the end of the 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 each
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 a Fund will be
voted by a Fund's shareholders individually when the matter affects the specific
interest of that Fund only, such as approval of its investment management
arrangements. In addition, each class of shares of a Fund has exclusive voting
rights with respect to its distribution plan. The shares of each Fund and of 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 shares may call a meeting of
shareholders for the purpose of voting upon the question of removal of any
Director or for any other

                             GT GLOBAL INCOME FUNDS
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
Strategic Income Fund and the High Income Fund; 100 million shares of each Fund
have been classified as Class A and Class B shares, respectively. In addition,
500 million shares have been classified as shares of Government Income Fund; 200
million shares have each been classified as Class A and Class B shares,
respectively. Moreover, 100 million shares have been classified as Advisor Class
shares of each Fund. This amount may be increased from time to time in the
discretion of the Board of Directors. Each share of a Fund represents an
interest in that Fund only, has a par value of $0.0001 per share, represents an
equal proportionate interest in that 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 that Fund as may be declared at the
discretion of the Board of Directors. Each Class A, Class B and Advisor Class
share of a 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 each Fund, when issued, are fully paid and
nonassessable.
 
ORGANIZATION OF THE PORTFOLIO. The Portfolio is organized as a trust under the
laws of the state of New York. The Portfolio's Declaration of Trust provides
that the High Income Fund and other entities investing in the Portfolio (E.G.,
other investment companies, insurance company separate accounts and common and
commingled trust funds), if any, will each be liable for all obligations of the
Portfolio. However, the Directors of the Company believe that the risk of the
High Income Fund incurring financial loss on account of such liability is
limited to circumstances in which both inadequate insurance existed and the
Portfolio itself was unable to meet its obligations, and that neither the High
Income Fund nor its shareholders will be exposed to a material risk of liability
by reason of the High Income Fund's investing in the Portfolio. Any information
received from the Portfolio in the Portfolio shareholder report will be provided
to the High Income Fund's shareholders.
 
Whenever the High Income Fund is requested to vote on any proposal of the
Portfolio, the High Income Fund will hold a meeting of Fund shareholders and
will cast its vote as instructed by Fund shareholders. Shares for which no
voting instructions are received will be voted in the same proportion as the
shares for which voting instructions are received.
 
SHAREHOLDER INQUIRIES. Shareholder inquiries may be made by calling the Funds
toll free at (800) 223-2138 or by writing to the Funds at 50 California Street,
27th Floor, San Francisco, CA 94111.
 
PERFORMANCE INFORMATION. The Funds, from time to time, may include information
on their investment results and/or comparisons of their investment results to
various unmanaged indices or results of other mutual funds or groups of mutual
funds in advertisements, sales literature or reports furnished to present or
prospective shareholders. Investors should be aware that as of October 22, 1992,
the investment objectives of the Strategic Income Fund were changed from long-
term high capital appreciation, primarily and moderate income, secondarily, to
primarily high current income and secondarily capital appreciation. In addition,
the investment policies and limitations of the Strategic Income Fund were
modified.
 
In such materials, the Funds may quote their average annual total return
("Standardized Return"). Standardized Return is calculated separately for each
class of shares of each 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 a Fund. Standardized Return assumes
reinvestment of all dividends and other distributions.
 
In addition, in order to more completely represent the Funds' performance or
more accurately compare such performance to other measures of investment return,
the Funds also may include in advertisements, sales literature and shareholder
reports other total return performance data ("Non-Standardized Return").
Non-Standardized Return reflects percentage rates of return encompassing all
elements of return (i.e., 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
 
                               Prospectus Page 47
<PAGE>
                             GT GLOBAL INCOME FUNDS
which Standardized Return is quoted; it may consist of an aggregate or average
annual percentage rate of return, actual year-by-year rates or any combination
thereof. Non-Standardized Return may or may not take sales charges into account;
performance data calculated without taking the effect of sales charges into
account will be higher than data including the effect of such charges.
 
The Funds also may refer in advertising and promotional materials to their
yield, which will fluctuate over time. A Fund's yield shows the rate of income
that it earns on its investments, expressed as a percentage of the public
offering price of its shares. A Fund calculates yield by determining the
interest income it earned from its portfolio investments for a specified
thirty-day period (net of expenses), dividing such income by the average number
of shares outstanding, and expressing the result as an annualized percentage
based on the public offering price at the end of that thirty-day period. Yield
accounting methods differ from the methods used for other accounting purposes.
Accordingly, a Fund's yield may not equal the dividend income actually paid to
investors or the income reported in its financial statements. Yield is
calculated separately for each class of shares of each Fund.
 
The Funds' performance data reflects past performance and is not necessarily
indicative of future results. The Funds' investment results will vary from time
to time depending upon market conditions, the composition of their portfolios
and their operating expenses. These factors and possible differences in
calculation methods should be considered when comparing a Fund's investment
results with those published for other investment companies, other investment
vehicles and unmanaged indices. Each Fund's results also should be considered
relative to the risks associated with its investment objectives and policies.
See "Investment Results" in the Statement of Additional Information.
 
Each Fund's annual report contains additional information with respect to its
performance. The annual report is available to investors upon request and free
of charge.

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

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

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

                       INVESTMENT OBJECTIVES AND POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES
The  Government Income Fund primarily seeks  high current income and secondarily
seeks capital appreciation and protection of principal through active management
of the maturity structure and currency exposure of its portfolio. The  Strategic
Income  Fund and  the High  Income Fund primarily  seek high  current income and
secondarily seek capital appreciation. The High Income Fund seeks to achieve its
investment  objectives  by  investing  all  of  its  investable  assets  in  the
Portfolio,  which is  a non-diversified  open-end management  investment company
with investment objectives identical to those  of the Fund. Whenever the  phrase
"all  of the  High Income Fund's  investable assets"  is used herein  and in the
Prospectus, it means that the only investment securities held by the High Income
Fund will be its interest  in the Portfolio. The  High Income Fund may  withdraw
its  investment in the Portfolio  at any time, if the  Board of Directors of the
Company determines  that  it is  in  the best  interests  of the  Fund  and  its
shareholders  to do so. Upon any such  withdrawal, the High Income Fund's assets
would be invested in  accordance with the investment  policies of the  Portfolio
described below and in the Prospectus.
 
INVESTMENT IN EMERGING MARKETS
The  Portfolio seeks its objectives by investing, under normal circumstances, at
least 65% of its total assets in debt securities of issuers in emerging markets.
The Strategic Income Fund may invest up to 50% of its assets in debt  securities
of  issuers in emerging markets. The Strategic  Income Fund and the Portfolio do
not consider the following countries to be emerging markets: Australia, Austria,
Belgium,  Canada,  Denmark,   France,  Germany,  Ireland,   Italy,  Japan,   the
Netherlands,  New Zealand,  Norway, Spain, Sweden,  Switzerland, United Kingdom,
and United States.
 
In addition to the factors  set forth in the  Prospectus, the Manager will  also
consider,  when determining  what countries  constitute emerging  markets, data,
analysis, and  classification  of countries  published  or disseminated  by  the
International  Bank for  Reconstruction and  Development (commonly  known as the
World Bank) and the International Finance Corporation.
 
SELECTION OF DEBT INVESTMENTS
In  determining  the  appropriate  distribution  of  investments  among  various
countries  and geographic regions for the  Government Income Fund, the Strategic
Income Fund and the  Portfolio, the Manager  ordinarily considers the  following
factors: prospects for relative economic growth among the different countries in
which  the Government Income  Fund, the Strategic Income  Fund and the Portfolio
may invest;  expected  levels  of  inflation;  government  policies  influencing
business  conditions; the outlook  for currency relationships;  and the range of
the individual investment opportunities available to international investors.
 
The Government Income  Fund, the  Strategic Income  Fund and  the Portfolio  may
invest   in  the  following  types  of  money  market  instruments  (i.e.,  debt
instruments with less than  12 months remaining  until maturity) denominated  in
U.S.  dollars or other  currencies: (a) obligations issued  or guaranteed by the
U.S.   or   foreign   governments,   their   agencies,   instrumentalities    or
municipalities;  (b)  obligations  of  international  organizations  designed or
supported  by  multiple  foreign  governmental  entities  to  promote   economic
reconstruction  or  development;  (c)  finance  company  obligations,  corporate
commercial  paper  and  other   short-term  commercial  obligations:  (d)   bank
obligations  (including certificates of deposit,  time deposits, demand deposits
and bankers' acceptances), subject to the restriction that the Government Income
Fund, the Strategic Income Fund and the  Portfolio may not invest more than  25%
of  their respective total assets in  bank securities; (e) repurchase agreements
with respect to the  foregoing; and (f)  other substantially similar  short-term
debt securities with comparable characteristics.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES
   
With  respect to certain  countries, investments by  the Government Income Fund,
the Strategic  Income Fund  and the  Portfolio  presently may  be made  only  by
acquiring shares of other investment companies (including investment vehicles or
companies  advised by the  Manager or its  affiliates ("Affiliated Funds")) with
local governmental approval to invest in those countries. At such time as direct
investment in  these  countries is  allowed,  the Government  Income  Fund,  the
Strategic  Income Fund and the Portfolio  anticipate investing directly in these
markets. The Government Income Fund, the Strategic

Income Fund and the  Portfolio may also invest  in the securities of  closed-end
investment companies within the limits of the Investment Company Act of 1940, as
amended  ("1940 Act"). These limitations currently provide that, in part, a Fund
or the Portfolio may  purchase shares of another  investment company unless  (a)
such  a purchase  would cause the  Government Income Fund,  the Strategic Income
Fund or  the Portfolio  to  own in  the  aggregate more  than  3% of  the  total
outstanding  voting securities of the investment  company or (b) such a purchase
would cause  the  Government Income  Fund,  the  Strategic Income  Fund  or  the
Portfolio  to have more than  5% of its total  assets invested in the investment
company or more than 10% of its aggregate assets invested in an aggregate of all
such investment  companies.  The  foregoing  limitations do  not  apply  to  the
investment  by the High  Income Fund in the  Portfolio. Investment in investment
companies may involve  the payment of  substantial premiums above  the value  of
such  companies' portfolio securities. The Government Income Fund, the Strategic
Income Fund  and  the Portfolio  do  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  a Fund  invested in Affiliated
Funds.
    
 
SAMURAI AND YANKEE BONDS
The Government Income  Fund, the  Strategic Income  Fund and  the Portfolio  may
invest  in yen-denominated bonds sold in Japan by non-Japanese issuers ("Samurai
bonds"), and may invest in dollar-denominated bonds sold in the United States by
non-U.S. issuers ("Yankee  bonds"). It is  the policy of  the Government  Income
Fund, the Strategic Income Fund and the Portfolio to invest in Samurai or Yankee
bond  issues  only  after  taking into  account  considerations  of  quality and
liquidity, as well as yield.
 
WARRANTS OR RIGHTS
Warrants or rights may be acquired by the Government Income Fund, the  Strategic
Income  Fund or the Portfolio in  connection with other securities or separately
and provide a Fund or the Portfolio with  the right to purchase at a later  date
other securities of the issuer.
 
LENDING OF PORTFOLIO SECURITIES
For  the purpose of realizing additional income, the Government Income Fund, the
Strategic Income  Fund or  the Portfolio  may make  secured loans  of  portfolio
securities  amounting to not more than 30% of its total assets. Securities loans
are made to  broker/dealers or  institutional investors  pursuant to  agreements
requiring that the loans continuously be secured by collateral at least equal at
all times to the value of the securities lent plus any accrued interest, "marked
to  market" on  a daily basis.  The Funds  and the Portfolio  may pay reasonable
administrative and custodial fees  in connection with  loans of its  securities.
While  the  securities  loan is  outstanding,  the Government  Income  Fund, the
Strategic Income Fund and the Portfolio will continue to receive the  equivalent
of  the interest or dividends  paid by the issuer on  the securities, as well as
interest on the investment  of the collateral  or a fee  from the borrower.  The
Government  Income Fund, the  Strategic Income Fund and  the Portfolio each will
have a right  to call  each loan  and obtain  the securities  within the  stated
settlement period. The Government Income Fund, the Strategic Income Fund and the
Portfolio will not have the right to vote equity securities while they are lent,
but each may call in a loan in anticipation of any important vote. Loans will be
made  only to firms deemed by the 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 Strategic  Income Fund's and the Portfolio's  investment
policies  with respect to  bank obligations, obligations  of foreign branches of
U.S. banks and of foreign banks are  obligations of the issuing bank and may  be
general  obligations  of  the parent  bank.  Such obligations,  however,  may be
limited by the terms of a  specific obligation and by government regulation.  As
with   investment  in  non-U.S.  securities   in  general,  investments  in  the
obligations of foreign branches of U.S.  banks and of foreign banks may  subject
the  the Strategic Income  Fund and the  Portfolio to investment  risks that are
different in some respects from those of investments in obligations of  domestic
issuers.  Although the  Strategic Income Fund  and the  Portfolio typically will
acquire obligations issued and supported by the credit of U.S. or foreign  banks
having  total assets at  the time of purchase  in excess of  $1 billion, this $1
billion figure is not an investment policy or restriction of either Fund or  the
Portfolio.  For  the purposes  of  calculation with  respect  to the  $1 billion
figure, the assets of a  bank will be deemed to  include the assets of its  U.S.
and non-U.S. branches.
 
REPURCHASE AGREEMENTS
A  repurchase agreement is a  transaction in which the  Fund or Portfolio buys a
security from a bank or recognized securities dealer and simultaneously  commits
to  resell that security to the bank or dealer at an agreed upon price, date and
market rate  of  interest  unrelated to  the  coupon  rate or  maturity  of  the
purchased security. Although repurchase agreements carry

                             GT GLOBAL INCOME FUNDS
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 Funds or Portfolio if  the other party to the repurchase  agreement
becomes  bankrupt, the Government Income Fund, the Strategic Income Fund and the
Portfolio intend  to  enter  into  repurchase agreements  only  with  banks  and
broker/dealers  believed  by  the Manager  to  present minimal  credit  risks in
accordance with guidelines  approved by  the Company's Board  of Directors.  The
Manager reviews and monitors the creditworthiness of such institutions under the
Board's general supervision.
 
The  Government Income  Fund, the Strategic  Income Fund and  the Portfolio will
invest only in repurchase agreements collateralized at all times in an amount at
least equal to the  repurchase price plus accrued  interest. To the extent  that
the  proceeds from any sale of such  collateral upon a default in the obligation
to repurchase were less than the  repurchase price, the Government Income  Fund,
the Strategic Income Fund or the Portfolio would suffer a loss. If the financial
institution  which is party to the repurchase agreement petitions for bankruptcy
or otherwise  becomes subject  to bankruptcy  or other  liquidation  proceedings
there  may be restrictions  on the Government Income  Fund, the Strategic Income
Fund's or the  Portfolio's ability  to sell  the collateral  and the  Government
Income  Fund, the Strategic  Income Fund or  the Portfolio could  suffer a loss.
However, with respect to financial institutions whose bankruptcy or  liquidation
proceedings are subject to the U.S. Bankruptcy Code, the Government Income Fund,
the  Strategic Income  Fund and the  Portfolio intend to  comply with provisions
under such Code that  would allow the immediate  resale of such collateral.  The
Government  Income  Fund  will not  enter  into  a repurchase  agreement  with a
maturity of more than seven days if, as a result, more than 10% of the value  of
its  total  assets would  be invested  in such  repurchase agreements  and other
illiquid investments  and  securities  for which  no  readily  available  market
exists.
 
BORROWING, REVERSE REPURCHASE AGREEMENTS AND "ROLL" TRANSACTIONS
The  Government Income Fund's borrowings will not exceed 30% 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 Strategic Income
Fund's and the Portfolio's borrowings will  not exceed 33 1/3% of the  Strategic
Income Fund's or the Portfolio's, respective total assets. The Government Income
Fund,  the Strategic Income Fund  and the Portfolio each may  borrow up to 5% of
its respective total assets  for temporary or emergency  purposes other than  to
meet  redemptions. Any borrowing  by a Fund  or the Portfolio  may cause greater
fluctuation in the value of its shares than would be the case if the Fund or the
Portfolio did not borrow.
 
The Government Income Fund's,  the Strategic Income  Fund's and the  Portfolio's
fundamental  investment  limitations permit  it to  borrow money  for leveraging
purposes. The Government Income 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.  The Strategic Income
Fund and Portfolio may borrow for  leveraging purposes. If the Strategic  Income
Fund  or  the  Portfolio  employs  leverage,  it  would  be  subject  to certain
additional risks. Use of leverage creates  an opportunity for greater growth  of
capital  but would exaggerate  any increases or  decreases in the  Fund's or the
Portfolio's net asset value. When the  income and gains on securities  purchased
with  the  proceeds  of borrowings  exceed  the  costs of  such  borrowings, the
Government Income  Fund's,  the  Strategic  Income  Fund's  or  the  Portfolio's
earnings  or net asset  value will increase  faster than otherwise  would be the
case; conversely, if such income and gains fail to exceed such costs, the Fund's
or the Portfolio's earnings or net  asset value would decline faster than  would
otherwise be the case.
 
The  Government Income  Fund, the  Strategic Income  Fund and  the Portfolio may
enter into reverse repurchase  agreements. A reverse  repurchase agreement is  a
borrowing transaction in which a Fund or the Portfolio transfers possession of a
security  to another party, such as a bank or broker/dealer, in return for cash,
and agrees to repurchase  the security in  the future at  an agreed upon  price,
which  includes an interest component. The Government Income Fund, the Strategic
Income Fund and the Portfolio also  may engage in "roll" borrowing  transactions
which  involve a Fund's or the  Portfolio's sale of Government National Mortgage
Association certificates or  other securities  together with  a commitment  (for
which  a Fund or the  Portfolio may receive a fee)  to purchase similar, but not
identical, securities  at  a  future  date.  The  Government  Income  Fund,  the
Strategic  Income Fund and the Portfolio  will maintain, in a segregated account
with a custodian, cash or liquid securities in an amount sufficient to cover its
obligations under  "roll" transactions  and reverse  repurchase agreements  with
broker/dealers.  No segregation  is required  for reverse  repurchase agreements
with banks.

SHORT SALES
The Government Income Fund, the Strategic Income Fund and the Portfolio may make
short sales of securities, although they have no current intention of doing  so.
A  short sale is a transaction in which a Fund or the Portfolio sells a security
in anticipation  that  the market  price  of  that security  will  decline.  The
Government  Income Fund,  the Strategic Income  Fund and the  Portfolio may make
short sales as a form of hedging to offset potential declines in long  positions
in  securities  it owns,  or  anticipates acquiring,  and  in order  to maintain
portfolio flexibility. The Government Income Fund, the Strategic Income Fund and
the Portfolio only may make short sales "against the box." In this type of short
sale, at the time of  the sale, the Fund or  the Portfolio owns the security  it
has  sold short  or has  the immediate  and unconditional  right to  acquire the
identical security at no additional cost.
 
In a short sale, the seller does not immediately deliver the securities sold and
does not receive the proceeds from the sale. To make delivery to the  purchaser,
the  executing broker borrows the  securities being sold short  on behalf of the
seller. The seller is said to have a short position in the securities sold until
it delivers the securities sold, at which  time it receives the proceeds of  the
sale.  To secure its obligation to deliver securities sold short, the Government
Income Fund,  the Strategic  Income Fund  or  the Portfolio  will deposit  in  a
separate account with its custodian an equal amount of the securities sold short
or  securities convertible into or exchangeable  for such securities at no cost.
The Government Income  Fund, the Strategic  Income Fund or  the Portfolio  could
close  out a short position by purchasing  and delivering an equal amount of the
securities sold short, rather than by delivering securities already held by  the
Fund  or the Portfolio, because the Fund or the Portfolio might want to continue
to receive interest and  dividend payments on securities  in its portfolio  that
are convertible into the securities sold short.
 
   
The  Government Income Fund,  the Strategic Income Fund  and the Portfolio 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  Government Income Fund, the Strategic
Income Fund or the Portfolio or a security convertible into or exchangeable  for
such  security. In such case, any future losses in the Government Income Fund's,
the Strategic Income  Fund's Fund  or the  Portfolio's long  position should  be
reduced  by  a gain  in the  short position.  Conversely, any  gain in  the long
position should be reduced by a loss in the short position. The extent to  which
such  gains or  losses in  the long  position are  reduced will  depend upon the
amount of the securities sold short relative to the amount of the securities the
Fund or the  Portfolio owns,  either directly or  indirectly, and,  in the  case
where  a  Fund or  the  Portfolio owns  convertible  securities, changes  in the
investment values  or conversion  premiums  of such  securities. There  will  be
certain  additional transaction costs  associated with short  sales "against the
box," but a  Fund or  the Portfolio  will endeavor  to offset  these costs  with
income from the investment of the cash proceeds of short sales.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use of options, futures contracts  and forward currency contracts ("Forward
Contracts") involves special considerations and risks, as described below. Risks
pertaining to particular instruments are described in the sections that follow.
 
        (1) Successful  use  of  most  of these  instruments  depends  upon  the
    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 or the Portfolio
    entered into a short  hedge because the Manager  projected a decline in  the
    price  of a  security in  the Fund's or  the Portfolio's  portfolio, and the
    price of that security increased instead, the gain from that increase  might
    by  wholly or  partially offset  by a  decline in  the price  of the hedging
    instrument. Moreover, if  the price  of the hedging  instrument declined  by
    more  than  the increase  in  the price  of the  security,  the Fund  or the
    Portfolio could  suffer  a  loss. In  either  such  case, the  Fund  or  the
    Portfolio would have been in a better position had it not hedged at all.
 
        (4)  As described below,  a Fund or  the Portfolio might  be required to
    maintain assets  as "cover,"  maintain segregated  accounts or  make  margin
    payments  when it  takes positions  in instruments  involving obligations to
    third parties (I.E., instruments other than purchased options). If a Fund or
    the Portfolio were unable to close out its positions in such instruments, it
    might be required to  continue to maintain such  assets or accounts or  make
    such  payments until the position expired or matured. The requirements might
    impair the Fund's  ability or the  Portfolio's ability to  sell a  portfolio
    security  or  make  an investment  at  a  time when  it  would  otherwise be
    favorable to  do so,  or  require that  the Fund  or  the Portfolio  sell  a
    portfolio  security at a disadvantageous time. The Fund's or the Portfolio's
    ability to close  out a  position in an  instrument prior  to expiration  or
    maturity  depends on the existence  of a liquid secondary  market or, in the
    absence of such a market, the ability and willingness of the other party  to
    the transaction ("contra party") to enter into a transaction closing out the
    position.  Therefore, there is no assurance  that any position can be closed
    out at a time and price that is favorable to the Fund or the Portfolio.
 
WRITING CALL OPTIONS
The Government Income  Fund, the  Strategic Income  Fund and  the Portfolio  may
write  (sell) call options  on securities, indices  and currencies. Call options
generally will be written on securities  and currencies that, in the opinion  of
the  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
Government Income Fund, the Strategic Income Fund and the Portfolio.
 
A  call option  gives the  holder (buyer)  the right  to purchase  a security or
currency at a specified price (the  exercise price) at any time until  (American
Style)  or on (European Style) a certain  date (the expiration date). So long as
the obligation of the writer of a  call option continues, he may be assigned  an
exercise  notice, requiring him  to deliver the  underlying security or currency
against payment  of the  exercise  price. This  obligation terminates  upon  the
expiration  of the call option, or such earlier time at which the writer effects
a closing  purchase  transaction  by  purchasing an  option  identical  to  that
previously sold.
 
                   Statement of Additional Information Page 6
<PAGE>
                             GT GLOBAL INCOME FUNDS
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on  the basis  of investment considerations  consistent with  a
Fund's or the Portfolio's investment objectives. When writing a call option, the
Government  Income Fund, the  Strategic Income Fund or  the Portfolio, in return
for the premium, gives up  the opportunity for profit  from a price increase  in
the  underlying security or  currency above the exercise  price, and retains the
risk of loss should the  price of the security  or currency decline. Unlike  one
who  owns  securities or  currencies not  subject to  an option,  a Fund  or the
Portfolio has no control  over when it  may be required  to sell the  underlying
securities  or currencies, since most options may be exercised at any time prior
to the option's expiration. If  a call option that a  Fund or the Portfolio  has
written  expires, the Fund or the Portfolio will realize a gain in the amount of
the premium; however, such gain may be  offset by a decline in the market  value
of  the underlying security  or currency during  the option period.  If the call
option is exercised, the Fund or the Portfolio will realize a gain or loss  from
the  sale of  the underlying  security or currency,  which will  be increased or
offset by the premium received. The Government Income Fund, the Strategic Income
Fund and the Portfolio do not consider a security or currency covered by a  call
option to be "pledged" as that term is used in the Government Income Fund's, the
Strategic  Income Fund's and the  Portfolio's fundamental investment policy that
limits the pledging or mortgaging of its assets.
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option will be exercised  and a Fund or the Portfolio will
be obligated to sell the security or currency at less than its market value.
 
The premium that the  Government Income Fund, the  Strategic Income Fund or  the
Portfolio  receives for writing a call option is deemed to constitute the market
value of  an option.  The premium  a Fund  or the  Portfolio will  receive  from
writing a call option will reflect, among other things, the current market price
of  the underlying  investment, the relationship  of the exercise  price to such
market price, the historical price volatility of the underlying investment,  and
the length of the option period. In determining whether a particular call option
should  be  written,  the  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 Government Income
Fund, the Strategic Income Fund or the Portfolio to write another call option on
the underlying  security or  currency with  either a  different exercise  price,
expiration date or both.
 
The Government Income Fund, the Strategic Income Fund and the Portfolio will pay
transaction costs in connection with the writing of options and in entering into
closing  purchase  contracts.  Transaction costs  relating  to  options activity
normally are higher than  those applicable to purchases  and sales of  portfolio
securities.
 
The  exercise price of the  options may be below, equal  to or above the current
market values of the underlying securities or currencies at the time the options
are written.  From  time to  time,  a Fund  or  the Portfolio  may  purchase  an
underlying  security or currency for delivery in accordance with the exercise of
an option, rather than delivering such security or currency from its  portfolio.
In such cases, additional costs will be incurred.
 
A  Fund or the Portfolio  will realize a profit or  loss from a closing purchase
transaction if the cost of the  transaction is less or more, respectively,  than
the  premium received from  writing the option. Because  increases in the market
price of a call option generally will  reflect increases in the market price  of
the underlying security or currency, any loss resulting from the repurchase of a
call  option is likely to be  offset in whole or in  part by appreciation of the
underlying security or currency owned by a Fund or the Portfolio.
 
WRITING PUT OPTIONS
The Government Income  Fund, the  Strategic Income  Fund and  the Portfolio  may
write  put options on securities, indices and currencies. A put option gives the
purchaser of  the  option  the  right  to sell,  and  the  writer  (seller)  the
obligation  to buy, the underlying security or currency at the exercise price at
anytime until (American Style) or on  (European Style) the expiration date.  The
operation  of put options  in other respects, including  their related risks and
rewards, is substantially identical to that of call options.
 
A Fund or the Portfolio generally would write put options in circumstances where
the Manager  wishes to  purchase the  underlying security  or currency  for  the
Fund's  or the Portfolio's  portfolio at a  price lower than  the current market
price of the  security or currency.  In such  event, the Fund  or the  Portfolio
would  write a  put option  at an  exercise price  that, reduced  by the premium
received on the option, reflects the lower price it is willing to pay. Since the
Fund or  the  Portfolio  also  would receive  interest  on  debt  securities  or
currencies  maintained to cover the exercise price of the option, this technique
 
                   Statement of Additional Information Page 7
<PAGE>
                             GT GLOBAL INCOME FUNDS
could be used to  enhance current return during  periods of market  uncertainty.
The  risk in such a transaction would be that the market price of the underlying
security or currency  would decline below  the exercise price  less the  premium
received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected that the put  option will be exercised and  a Fund or the Portfolio
will be  obligated to  purchase the  security or  currency at  greater than  its
market value.
 
PURCHASING PUT OPTIONS
The  Government Income  Fund, the  Strategic Income  Fund and  the Portfolio may
purchase put options on securities, indices  and currencies. As the holder of  a
put  option,  the  Government Income  Fund,  the  Strategic Income  Fund  or the
Portfolio would have the  right to sell the  underlying security or currency  at
the  exercise price at any time until (American Style or on (European Style) the
expiration date. The Government  Income Fund, the Strategic  Income Fund or  the
Portfolio may enter into closing sale transactions with respect to such options,
exercise them or permit them to expire.
 
A  Fund or the Portfolio may purchase a  put option on an underlying security or
currency ("protective put")  owned by  the Fund or  the Portfolio  as a  hedging
technique in order to protect against an anticipated decline in the value of the
security  or currency. Such hedge protection is provided only during the life of
the put option when the Fund or the Portfolio, as the holder of the put  option,
is  able to sell the  underlying security or currency  at the put exercise price
regardless  of  any  decline  in  the  underlying  security's  market  price  or
currency's  exchange  value.  The  premium  paid  for  the  put  option  and any
transaction costs would reduce any  profit otherwise available for  distribution
when the security or currency eventually is sold.
 
The Government Income Fund, the Strategic Income Fund and the Portfolio also may
purchase  put options at a time when that Fund or the Portfolio does not own the
underlying security or  currency. By  purchasing put  options on  a security  or
currency  it does  not own,  a Fund  or the  Portfolio seeks  to benefit  from a
decline in the market price of the  underlying security or currency. If the  put
option  is not sold when it has remaining  value, and if the market price of the
underlying security or currency  remains equal to or  greater than the  exercise
price during the life of the put option, the Fund or the Portfolio will lose its
entire  investment in the put option. In order  for the purchase of a put option
to be profitable, the market price  of the underlying security or currency  must
decline  sufficiently  below  the  exercise  price  to  cover  the  premium  and
transaction costs, unless the put option is sold in a closing sale transaction.
 
PURCHASING CALL OPTIONS
The Government  Income Fund,  the Strategic  Income Fund  or the  Portfolio  may
purchase  call options on securities, indices and currencies. As the holder of a
call option,  a Fund  or the  Portfolio would  have the  right to  purchase  the
underlying  security  or  currency  at  the exercise  price  at  any  time until
(American Style)  or on  (European Style)  the expiration  date. A  Fund or  the
Portfolio may enter into closing sale transactions with respect to such options,
exercise them or permit them to expire.
 
Call  options may  be purchased by  a Fund or  the Portfolio for  the purpose of
acquiring the underlying  security or  currency for its  portfolio. Utilized  in
this  fashion,  the  purchase of  call  options  would enable  the  Fund  or the
Portfolio to acquire the security or currency at the exercise price of the  call
option  plus the premium paid. At times,  the net cost of acquiring the security
or currency in this manner may be  less than the cost of acquiring the  security
or  currency  directly. This  technique  also may  be useful  to  a Fund  or the
Portfolio in purchasing a large block of securities that would be more difficult
to acquire by direct market purchases. So  long as it holds such a call  option,
rather  than the underlying security or currency itself, a Fund or the Portfolio
is partially protected from  any unexpected decline in  the market price of  the
underlying  security or currency and, in such event, could allow the call option
to expire, incurring  a loss  only to  the extent of  the premium  paid for  the
option.
 
The Government Income Fund, the Strategic Income Fund and the Portfolio also may
purchase  call options on  underlying securities or currencies  it owns to avoid
realizing losses that would result in a reduction of a Fund's or the Portfolio's
current return. For example, where  a Fund or the  Portfolio has written a  call
option on an underlying security or currency having a current market value below
the  price at which  it purchased the  security or currency,  an increase in the
market price could result in the exercise of the call option written by the Fund
or the Portfolio and  the realization of  a loss on  the underlying security  or
currency. Accordingly, the Fund or the Portfolio could purchase a call option on
the  same underlying security  or currency, which could  be exercised to fulfill
the Fund's or the Portfolio's delivery obligations under its written call (if it
is exercised). This  strategy could  allow the Fund  or the  Portfolio to  avoid
selling  the portfolio security or currency at  a time when it has an unrealized
loss; however, the Fund or the Portfolio would have to pay a premium to purchase
the call option plus transaction costs.

Aggregate premiums paid for put and call options will not exceed 5% of a  Fund's
or the Portfolio's total assets at the time of purchase.
 
The  Government  Income Fund,  the Strategic  Income Fund  or the  Portfolio may
attempt to  accomplish objectives  similar to  those involved  in using  Forward
Contracts  by purchasing put or call options on currencies. A put option gives a
Fund or the Portfolio as purchaser the right (but not the obligation) to sell  a
specified  amount of currency at the exercise  price at any time until (American
Style) or on (European Style) the expiration of the option. A call option  gives
a  Fund or  the Portfolio  as purchaser  the right  (but not  the obligation) to
purchase a specified amount of currency at the exercise price at any time  until
(American  Style) or on (European Style) the expiration of the option. A Fund or
the Portfolio might  purchase a  currency put  option, for  example, to  protect
itself  against a decline in the dollar value of a currency in which it holds or
anticipates holding securities. If the  currency's value should decline  against
the dollar, the loss in currency value should be offset, in whole or in part, by
an increase in the value of the put. If the value of the currency instead should
rise  against the dollar, any gain to the Fund or the Portfolio would be reduced
by the premium it had paid for the  put option. A currency call option might  be
purchased, for example, in anticipation of, or to protect against, a rise in the
value  against  the dollar  of a  currency in  which the  Fund or  the Portfolio
anticipates purchasing securities.
 
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing corporation), and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates.  The Funds and the  Portfolio will not purchase  an OTC option unless the
Fund or  the Portfolio  believes  that daily  valuations  for such  options  are
readily  obtainable. OTC options differ from exchange-traded options in that OTC
options are  transacted  with  dealers  directly  and  not  through  a  clearing
corporation  (which guarantees  performance). Consequently,  there is  a risk of
non-performance by the dealer.  Since no exchange is  involved, OTC options  are
valued on the basis of the average of the last bid prices obtained from dealers,
unless  a quotation from only  one dealer is available,  in which case only that
dealer's price  will be  used. In  the  case of  OTC options,  there can  be  no
assurance that a liquid secondary market will exist for any particular option at
any specific time.
 
The  staff of the Securities and Exchange Commission ("SEC") considers purchased
OTC options to be illiquid securities. A Fund or the Portfolio may also sell OTC
options and, in connection therewith, segregate assets or cover its  obligations
with  respect to OTC  options written by  the Fund or  the Portfolio. The assets
used as  cover for  OTC options  written  by a  Fund or  the Portfolio  will  be
considered  illiquid unless  the OTC options  are sold to  qualified dealers who
agree that the Fund or the Portfolio may repurchase any OTC option it writes  at
a maximum price to be calculated by a formula set forth in the option agreement.
The  cover  for  an  OTC  option written  subject  to  this  procedure  would be
considered illiquid only to the extent  that the maximum repurchase price  under
the formula exceeds the intrinsic value of the option.
 
A  Fund's or  the Portfolio's  ability to establish  and close  out positions in
exchange-listed options depends on the existence  of a liquid market. Each  Fund
and  the  Portfolio  intends to  purchase  or write  only  those exchange-traded
options for which there appears to be a liquid secondary market. However,  there
can  be  no assurance  that such  a market  will exist  at any  particular time.
Closing transactions can be  made for OTC options  only by negotiating  directly
with  the contra party or  by a transaction in the  secondary market if any such
market exists. Although each Fund and the Portfolio will enter into OTC  options
only  with  contra parties  that are  expected  to be  capable of  entering into
closing transactions with the Fund or the Portfolio, there is no assurance  that
the  Fund or  the Portfolio  will in  fact be  able to  close out  an OTC option
position at a favorable price prior  to expiration. In the extent of  insolvency
of  the contra party, the Fund or the  Portfolio might be unable to close out an
OTC option position at any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts except that all settlements  are in cash and  gain or loss depends  on
changes  in the index in question (and thus on price movements in the securities
market or a particular market sector  generally) rather than on price  movements
in  individual securities  or futures  contracts. When  a Fund  or the Portfolio
writes a call on an index, it receives  a premium and agrees that, prior to  the
expiration  date, the  purchaser of  the call, upon  exercise of  the call, will
receive from the Fund or the Portfolio an amount of cash if the closing level of
the index upon which the call is based is greater than the exercise price of the
call. The amount of cash is equal to the difference between the closing price of
the index and the  exercise price of  the call times  a specified multiple  (the
"multiplier"),  which determines the  total dollar value for  each point of such
difference. When a  Fund or the  Portfolio buys a  call on an  index, it pays  a
premium  and has the same rights as to  such call as are indicated above. When a
Fund or the Portfolio  buys a put  on an index,  it pays a  premium and has  the
right,  prior to the expiration date, to require the seller of the put, upon the
Fund's or the Portfolio's  exercise of the  put, to deliver to  the Fund or  the
Portfolio an amount of cash if the closing level of the index upon which the put
is  based is less  than the exercise price  of the put, which  amount of cash is
 
                   Statement of Additional Information Page 9
<PAGE>
                             GT GLOBAL INCOME FUNDS
determined by the multiplier, as described above  for calls. When a Fund or  the
Portfolio  writes a put on an index, it receives a premium and the purchaser has
the right, prior to the expiration date, to require the Fund or the Portfolio to
deliver to it  an amount of  cash equal  to the difference  between the  closing
level  of the index and the exercise  price times the multiplier, if the closing
level is less than the exercise price.
 
The risks  of  investment  in index  options  may  be greater  than  options  on
securities.  Because  index options  are settled  in  cash, when  a Fund  or the
Portfolio writes  a call  on  an index  it cannot  provide  in advance  for  its
potential  settlement  obligations  by  acquiring  and  holding  the  underlying
securities. A Fund or  the Portfolio can  offset some of the  risk of writing  a
call  index option  position by  holding a  diversified portfolio  of securities
similar to those on which the underlying index is based. However, a Fund or  the
Portfolio cannot, as a practical matter, acquire and hold a portfolio containing
exactly the same securities as underlie the index and, as a result, bears a risk
that the value of the securities held will vary from the value of the index.
 
Even  if a  Fund or  the Portfolio  could assemble  a securities  portfolio that
exactly reproduced the composition of the  underlying index, it still would  not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing  index options. When  an index option  is exercised, the  amount of cash
that the holder is entitled to  receive is determined by the difference  between
the  exercise price and the  closing index level on the  date when the option is
exercised. As with other  kinds of options,  the Fund or  the Portfolio, as  the
call writer, will not know that it has been assigned until the next business day
at the earliest. The time lag between exercise and notice of assignment poses no
risk for the writer of a covered call on a specific underlying security, such as
common stock, because there the writer's obligation is to deliver the underlying
security,  not to pay its value  as of a fixed time in  the past. So long as the
writer already  owns the  underlying  security, it  can satisfy  its  settlement
obligations  by  simply delivering  it, and  the  risk that  its value  may have
declined since the exercise date is borne by the exercising holder. In contrast,
even if the  writer of an  index call  holds securities that  exactly match  the
composition  of  the  underlying index,  it  will  not be  able  to  satisfy its
assignment obligations by  delivering those  securities against  payment of  the
exercise  price. Instead, it will be required to  pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that  it
has  been assigned, the index may have declined, with a corresponding decline in
the value  of  its securities  portfolio.  This  "timing risk"  is  an  inherent
limitation  on the ability of index call writers to cover their risk exposure by
holding securities positions.
 
If a Fund or the Portfolio purchases an index option and exercises it before the
closing index value for that day is  available, it runs the risk that the  level
of  the underlying index  may subsequently change.  If such a  change causes the
exercised option to  fall out-of-the-money, the  Fund or the  Portfolio will  be
required  to pay the difference between the closing index value and the exercise
price of the option (times the applicable multiplier) to the assigned writer.
 
INTEREST RATE AND CURRENCY FUTURES CONTRACTS
The Government Income Fund, the Strategic Income Fund or the Portfolio may enter
into interest rate or currency futures contracts, including futures contracts on
indices of  debt securities,  ("Futures"  or "Futures  Contracts"), as  a  hedge
against  changes in  prevailing levels  of interest  rates or  currency exchange
rates in order to establish more  definitely the effective return on  securities
or  currencies held or intended to be acquired by the Fund or the Portfolio. The
Government Income Fund, the Strategic  Income Fund's or the Portfolio's  hedging
may  include  sales of  Futures  as an  offset  against the  effect  of expected
increases in  interest  rates  or  decreases in  currency  exchange  rates,  and
purchases  of Futures as  an offset against  the effect of  expected declines in
interest rates or increases in currency exchange rates.
 
The Government Income Fund's, the Strategic  Income Fund and the Portfolio  only
will  enter into Futures Contracts that are  traded on futures exchanges and are
standardized as to  maturity date and  underlying financial instrument.  Futures
exchanges  and  trading thereon  in the  United States  are regulated  under the
Commodity Exchange Act  by the  Commodity Futures  Trading Commission  ("CFTC").
Futures  are exchanged in  London at the  London International Financial Futures
Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used to  reduce  a Fund's  or  the Portfolio's  exposure  to interest  rate  and
currency  exchange rate  fluctuations, a  Fund or the  Portfolio may  be able to
hedge exposure  more effectively  and  at a  lower  cost through  using  Futures
Contracts.
 
A  Futures Contract provides  for the future  sale by one  party and purchase by
another party of  a specified amount  of a specific  financial instrument  (debt
security  or currency)  for a  specified price  at a  designated date,  time and
place. An index  Futures Contract  provides for  the delivery,  at a  designated
date,  time and place, of  an amount of cash equal  to a specified dollar amount
times the difference  between the index  value at  the close of  trading on  the
contract  and the price at  which the Futures Contract  is originally struck; no
physical delivery  of the  securities comprising  the index  is made.  Brokerage

                             GT GLOBAL INCOME FUNDS
fees are incurred when a Futures Contract is bought or sold, and margin deposits
must be maintained at all times the Futures Contract is outstanding.
 
Although  Futures Contracts typically require future delivery of and payment for
financial instruments or  currencies, Futures Contracts  usually are closed  out
before  the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering  into an offsetting Futures  Contract purchase or  sale,
respectively,   for  the  same  aggregate  amount  of  the  identical  financial
instrument or currency and  the same delivery date.  If the offsetting  purchase
price  is less  than the  original sale price,  the Government  Income Fund, the
Strategic Income Fund  or the  Portfolio realizes  a gain;  if it  is more,  the
Government  Income Fund, the  Strategic Income Fund or  the Portfolio realizes a
loss. Conversely,  if  the offsetting  sale  price  is more  than  the  original
purchase  price, the  Government Income Fund,  the Strategic Income  Fund or the
Portfolio realizes  a gain;  if it  is  less, the  Government Income  Fund,  the
Strategic  Income Fund or  the Portfolio realizes a  loss. The transaction costs
also must be included in these calculations. There can be no assurance, however,
that a  Fund  or  the  Portfolio  will be  able  to  enter  into  an  offsetting
transaction  with respect to a particular Futures Contract at a particular time.
If a Fund or the Portfolio is not able to enter into an offsetting  transaction,
the  Fund or the Portfolio  will continue to be  required to maintain the margin
deposits on the Futures Contract.
 
As an example of an offsetting transaction, the contractual obligations  arising
from  the sale of one Futures Contract of September Deutschemarks on an exchange
may be  fulfilled at  any time  before delivery  under the  Futures Contract  is
required  (I.E., on a specified date in  September, the "delivery month") by the
purchase of  another Futures  Contract of  September Deutschemarks  on the  same
exchange.  In  such instance,  the  difference between  the  price at  which the
Futures Contract was sold and the price paid for the offsetting purchase,  after
allowance for transaction costs, represents the profit or loss to the Government
Income Fund, the Strategic Income Fund or the Portfolio.
 
The  Government Income  Fund, the  Strategic Income  Fund's and  the Portfolio's
Futures transactions will be  entered into for hedging  purposes only; that  is,
Futures  Contracts will  be sold to  protect against  a decline in  the price of
securities or  currencies  that the  Fund  or  the Portfolio  owns,  or  Futures
Contracts  will be  purchased to  protect the Fund  or the  Portfolio against an
increase in the price of securities  or currencies it has committed to  purchase
or expects to purchase.
 
"Margin"  with respect to Futures Contracts is  the amount of funds that must be
deposited by  the Government  Income  Fund, the  Strategic  Income Fund  or  the
Portfolio in order to initiate Futures trading and to maintain the Fund's or the
Portfolio's  open positions in Futures Contracts. A margin deposit made when the
Futures Contract is  entered into  ("initial margin")  is intended  to assure  a
Fund's  or the  Portfolio's performance under  the Futures  Contract. The margin
required for a particular Futures Contract is  set by the exchange on which  the
Futures  Contract is traded, and may be modified significantly from time to time
by the exchange during the term of the Futures Contract.
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission  merchant through  which the Fund  or the Portfolio  entered into the
Futures Contract will be made  on a daily basis as  the price of the  underlying
security,  currency or index fluctuates making the Futures Contract more or less
valuable, a process known as marking-to-market.
 
    RISKS OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts  are
volatile  and  are influenced,  among other  things,  by actual  and anticipated
changes in interest and currency rates, which in turn are affected by fiscal and
monetary policies and national and international political and economic events.
 
There is a risk  of imperfect correlation between  changes in prices of  Futures
Contracts  and  prices  of the  securities  or  currencies in  a  Fund's  or the
Portfolio's portfolio being  hedged. The degree  of imperfection of  correlation
depends  upon circumstances such as: variations in speculative market demand for
Futures and  for securities  or currencies,  including technical  influences  in
Futures  trading; and differences between the financial instruments being hedged
and the  instruments underlying  the standard  Futures Contracts  available  for
trading.  A  decision of  whether, when,  and  how to  hedge involves  skill and
judgment, and even  a well-conceived hedge  may be unsuccessful  to some  degree
because of unexpected market behavior or interest or currency rate trends.
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
                  Statement of Additional Information Page 11
<PAGE>
                             GT GLOBAL INCOME FUNDS
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and option on Futures Contract prices during a single trading day.  The
daily  limit establishes the maximum amount that the price of a Futures Contract
or option may vary either up or down from the previous day's settlement price at
the end  of a  trading session.  Once  the daily  limit has  been reached  in  a
particular type of Futures Contract or option, no trades may be made on that day
at a price beyond that limit. The daily limit governs only price movement during
a  particular trading day and therefore does not limit potential losses, because
the limit may prevent the liquidation of unfavorable positions. Futures Contract
and option  prices  occasionally have  moved  to  the daily  limit  for  several
consecutive  trading days with  little or no  trading, thereby preventing prompt
liquidation of positions and subjecting some traders to substantial losses.
 
If a Fund  or the  Portfolio were  unable to liquidate  a Futures  or option  on
Futures  position  due  to the  absence  of  a liquid  secondary  market  or the
imposition of price limits, it could  incur substantial losses. The Fund or  the
Portfolio  would  continue to  be subject  to  market risk  with respect  to the
position. In addition, except in the case of purchased options, the Fund or  the
Portfolio  would continue to be required to make daily variation margin payments
and might be required  to maintain the  position being hedged  by the Future  or
option or to maintain cash or securities in a segregated account.
 
Certain  characteristics  of the  Futures market  might  increase the  risk that
movements in the  prices of Futures  Contracts or options  on Futures might  not
correlate  perfectly  with  movements in  the  prices of  the  investments being
hedged. For example,  all participants  in the  Futures and  options on  Futures
markets  are subject to daily  variation margin calls and  might be compelled to
liquidate Futures  or  options on  Futures  positions whose  prices  are  moving
unfavorably  to avoid being  subject to further  calls. These liquidations could
increase price  volatility  of the  instruments  and distort  the  normal  price
relationship  between the Futures  or options and  the investments being hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous than  margin requirements  in  the securities  markets, there  might  be
increased   participation   by  speculators   in   the  Futures   markets.  This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage,  "program trading"  and other  investment strategies  might result in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options on Futures Contracts are similar to options on securities or  currencies
except that options on Futures Contracts give the purchaser the right, in return
for  the  premium paid,  to  assume a  position in  a  Futures Contract  (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price  at any time  during the period  of the option.  Upon
exercise  of the option, the  delivery of the Futures  position by the writer of
the option to the holder  of the option will be  accompanied by delivery of  the
accumulated balance in the writer's Futures margin account, which represents the
amount  by which the market price of  the Futures Contract, at exercise, exceeds
(in the case of  a call) or  is less than (in  the case of  a put) the  exercise
price  of the option on  the Futures Contract. If an  option is exercised on the
last trading day prior to the expiration date of the option, the settlement will
be made entirely in cash equal to  the difference between the exercise price  of
the  option and the  closing level of  the securities, currencies  or index upon
which the  Futures Contract  is  based on  the  expiration date.  Purchasers  of
options  who fail to exercise their options  prior to the exercise date suffer a
loss of the premium paid.
 
The purchase of  call options  on Futures  can serve as  a long  hedge, and  the
purchase  of put  options on Futures  can serve  as a short  hedge. Writing call
options on Futures can serve as a  limited short hedge, and writing put  options
on  Futures can serve as a limited long  hedge, using a strategy similar to that
used for writing options on securities, foreign currencies or indices.
 
If a Fund or the  Portfolio writes an option on  a Futures Contract, it will  be
required  to  deposit  initial  and variation  margin  pursuant  to requirements
similar to those  applicable to  Futures Contracts. Premiums  received from  the
writing  of an option on  a Futures Contract are  included in the initial margin
deposit.
 
A Fund or the Portfolio may seek to  close out an option position by selling  an
option covering the same Futures Contract and having the same exercise price and
expiration  date.  The ability  to  establish and  close  out positions  on such
options is subject to the maintenance of a liquid secondary market.
 
LIMITATIONS ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS  ON
CURRENCIES
To  the  extent that  a Fund  or  the Portfolio  enters into  Futures Contracts,
options on  Futures Contracts  and options  on foreign  currencies traded  on  a
CFTC-regulated  exchange, in each case other than for BONA FIDE hedging purposes
(as defined by the CFTC), the aggregate initial margin and premiums required  to
establish   those  positions  (excluding   the  amount  by   which  options  are
"in-the-money") will not exceed 5% of the  liquidation value of a Fund's or  the
Portfolio's   portfolio,  after  taking  into  account  unrealized  profits  and
unrealized losses on any contracts the  Fund or the Portfolio has entered  into.
In  general, a call option on a  Futures Contract is "in-the-money" if the value
of the underlying Futures
 
                  Statement of Additional Information Page 12

                             GT GLOBAL INCOME FUNDS
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  or the  Portfolio's  Board of
Trustees, as applicable, without  a shareholder vote.  This limitation does  not
limit the percentage of a Fund's or the Portfolio's assets at risk to 5%.
 
FORWARD CONTRACTS
A  Forward Contract is an obligation,  generally arranged with a commercial bank
or other  currency  dealer, to  purchase  or  sell a  currency  against  another
currency  at  a  future  date and  price  as  agreed upon  by  the  parties. The
Government Income Fund, the Strategic Income  Fund and the Portfolio either  may
accept or make delivery of the currency at the maturity of the Forward Contract.
A Fund or the Portfolio may also, if its contra party agrees, prior to maturity,
enter into a closing transaction involving the purchase or sale of an offsetting
contract.
 
A Fund or the Portfolio engages in forward currency transactions in anticipation
of,  or to protect itself against, fluctuations in exchange rates. A Fund or the
Portfolio might sell a particular foreign currency forward, for example, when it
holds bonds denominated in a foreign  currency but anticipates, and seeks to  be
protected against, a decline in the currency against the U.S. dollar. Similarly,
a  Fund or the Portfolio might sell the  U.S. dollar forward when it holds bonds
denominated in U.S. dollars but anticipates, and seeks to be protected  against,
a decline in the U.S. dollar relative to other currencies. Further, the Funds or
the  Portfolio  might purchase  a currency  forward  to "lock  in" the  price of
securities denominated in that currency that it anticipates purchasing.
 
Forward Contracts are traded in the interbank market conducted directly  between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any  stage for trades. The Government Income  Fund, the Strategic Income Fund or
the Portfolio will enter into such Forward Contracts with major U.S. or  foreign
banks  and securities or currency dealers in accordance with guidelines approved
by the Company's  Board of Directors  or the Portfolio's  Board of Trustees,  as
applicable.
 
The Government Income Fund, the Strategic Income Fund or the Portfolio may enter
into  Forward Contracts  either with  respect to  specific transactions  or with
respect to the  overall investment  of the Fund  or the  Portfolio. The  precise
matching  of the Forward  Contract amounts and the  value of specific securities
generally will not be  possible because the future  value of such securities  in
foreign currencies will change as a consequence of market movements in the value
of  those securities between the  date the Forward Contract  is entered into and
the date  it matures.  Accordingly, it  may be  necessary for  the Fund  or  the
Portfolio  to  purchase additional  foreign currency  on  the spot  (I.E., cash)
market (and  bear the  expense of  such purchase)  if the  market value  of  the
security  is less than the amount of  foreign currency the Fund or the Portfolio
is obligated to deliver and if a decision is made to sell the security and  make
delivery of the foreign currency. Conversely, it may be necessary to sell on the
spot  market some of the foreign currency the Fund or the Portfolio is obligated
to deliver. The projection of short-term currency market movements is  extremely
difficult,  and the  successful execution  of a  short-term hedging  strategy is
highly uncertain. Forward Contracts involve  the risk that anticipated  currency
movements will not be predicted accurately, causing the Fund or the Portfolio to
sustain losses on these contracts and transaction costs.
 
At  or  before the  maturity of  a Forward  Contract requiring  the Fund  or the
Portfolio to  sell a  currency, the  Fund or  the Portfolio  either may  sell  a
portfolio security and use the sale proceeds to make delivery of the currency or
retain  the  security  and  offset its  contractual  obligation  to  deliver the
currency by  purchasing a  second contract  pursuant to  which the  Fund or  the
Portfolio  will  obtain, on  the  same maturity  date,  the same  amount  of the
currency that it is obligated to  deliver. Similarly, the Fund or the  Portfolio
may  close out a Forward Contract requiring  it to purchase a specified currency
by entering into a second contract, if its contra party agrees, entitling it  to
sell  the same  amount of the  same currency on  the maturity date  of the first
contract. The Fund or the Portfolio would realize a gain or loss as a result  of
entering  into such an offsetting Forward  Contract under either circumstance to
the extent the  exchange rate  or rates  between the  currencies involved  moved
between the execution dates of the first contract and the offsetting contract.
 
The cost to a Fund or the Portfolio of engaging in Forward Contracts varies with
factors  such as the currencies involved, the  length of the contract period and
the market conditions  then prevailing.  Because Forward  Contracts usually  are
entered  into on a principal basis, no fees or commissions are involved. The use
of Forward  Contracts does  not  eliminate fluctuations  in  the prices  of  the
underlying  securities the Fund or the Portfolio owns or intends to acquire, but
it does establish  a rate  of exchange in  advance. In  addition, while  Forward
Contracts  limit the risk  of loss due to  a decline in the  value of the hedged
currencies, they also  limit any  potential gain  that might  result should  the
value of the currencies increase.

FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
A  Fund  or the  Portfolio may  use  options on  foreign currencies,  Futures on
foreign currencies,  options  on  Futures  on  foreign  currencies  and  Forward
Contracts  to hedge against movements in the values of the foreign currencies in
which the Fund's or  the Portfolio's securities  are denominated. Such  currency
hedges  can protect  against price movements  in a  security that a  Fund or the
Portfolio owns or  intends to acquire  that are attributable  to changes in  the
value  of the currency in which it  is denominated. Such hedges do not, however,
protect against price movements in the securities that are attributable to other
causes.
 
A Fund or the Portfolio  might seek to hedge against  changes in the value of  a
particular  currency  when  no  Futures  Contract,  Forward  Contract  or option
involving that currency is available or one of such contracts is more  expensive
than certain other contracts. In such cases, the Fund or the Portfolio may hedge
against  price movements in that currency by entering into a contract on another
currency or basket of currencies, the values of which the 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,  a Fund or the  Portfolio could be disadvantaged  by dealing in the odd
lot market (generally consisting  of transactions of less  than $1 million)  for
the  underlying foreign  currencies at prices  that are less  favorable than for
round lots.
 
There is no systematic reporting of last sale information for foreign currencies
or any  regulatory requirements  that quotations  available through  dealers  or
other market sources be firm or revised on a timely basis. Quotation information
generally  is representative of very large  transactions in the interbank market
and thus  might not  reflect  odd-lot transactions  where  rates might  be  less
favorable.   The   interbank  market   in  foreign   currencies  is   a  global,
round-the-clock market. To the  extent the U.S. options  or Futures markets  are
closed  while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that  cannot
be  reflected in  the markets  for the Futures  contracts or  options until they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies might  be required  to  take place  within  the country  issuing  the
underlying  currency. Thus, a Fund or the  Portfolio might be required to accept
or make delivery of the underlying foreign currency in accordance with any  U.S.
or foreign regulations regarding the maintenance of foreign banking arrangements
by  U.S. residents  and might  be required  to pay  any fees,  taxes and charges
associated with such delivery assessed in the issuing country.
 
COVER
Transactions using Forward Contracts, Futures Contracts and options (other  than
options  purchased by a Fund or the  Portfolio) expose the Fund or the Portfolio
to an obligation to another party. A  Fund or the Portfolio will not enter  into
any  such  transactions  unless it  owns  either (1)  an  offsetting ("covered")
position in  securities,  currencies, or  other  options, Forward  Contracts  or
Futures  Contracts, or (2) cash, receivables and short-term debt securities with
a value sufficient at all times  to cover its potential obligations not  covered
as  provided in  (1) above.  Each Fund  and the  Portfolio will  comply with SEC
guidelines regarding  cover for  these  instruments and,  if the  guidelines  so
require, set aside cash or liquid securities.
 
Assets  used as cover or  held in a segregated account  cannot be sold while the
position in the corresponding  Forward Contract, Futures  Contract or option  is
open, unless they are replaced with other appropriate assets. If a large portion
of a Fund's or the Portfolio's assets are used for cover or segregated accounts,
it could affect portfolio management or the Fund's or the Portfolio's ability to
meet redemption requests or other current obligations.
 
INTEREST RATE AND CURRENCY SWAPS
The  Strategic Income  Fund and the  Portfolio usually will  enter into interest
rate swaps on a net basis, that is, the two payment streams are netted out in  a
cash  settlement on the payment date or  dates specified in the instrument, with
the Strategic Income Fund or the Portfolio receiving or paying, as the case  may
be,  only the net amount of  the two payments. The net  amount of the excess, if
any, of each of the Strategic Income Fund's and the Portfolio's obligations over
its entitlements with respect to each swap will be accrued on a daily basis  and
an  amount of cash or  liquid securities having an  aggregate net asset value at
least equal  to  the accrued  excess  will be  maintained  in an  account  by  a
custodian  that satisfies the requirements of the 1940 Act. The Strategic Income
Fund and the Portfolio will also establish and maintain such segregated accounts
with respect to its total obligations under any swaps that are not entered  into
on  a net basis and with respect to any  caps or floors that are written by that
Fund  or   the  Portfolio.   The  Manager,   the  Strategic   Income  Fund   and
 
                  Statement of Additional Information Page 14
<PAGE>
                             GT GLOBAL INCOME FUNDS
the  Portfolio  believe that  swaps, caps  and floors  do not  constitute senior
securities under the  1940 Act and,  accordingly, will not  treat them as  being
subject  to the Fund's and the Portfolio's borrowing restrictions. The Strategic
Income Fund and the Portfolio will not  enter into any swap, cap, floor,  collar
or  other  derivative  transaction unless,  at  the  time of  entering  into the
transaction, the unsecured  long-term debt rating  of the counterparty  combined
with  any credit enhancements is rated at  least A by Moody's Investors Service,
Inc. ("Moody's")  or  Standard  &  Poor's  Ratings  Group  ("S&P"),  or  has  an
equivalent  rating from a nationally  recognized statistical rating organization
or is  determined to  be  of equivalent  credit quality  by  the Manager.  If  a
counterparty  defaults,  the Strategic  Income Fund  or  the Portfolio  may have
contractual remedies pursuant to the agreements related to the transactions. The
swap market has  grown substantially  in recent years,  with a  large number  of
banks  and  investment banking  firms acting  both as  principals and  as agents
utilizing standardized  swap documentation.  As a  result, the  swap market  has
become  relatively liquid. Caps, floors and  collars are more recent innovations
for which standardized documentation has not  yet been fully developed and,  for
that reason, they are less liquid than swaps.

                                  RISK FACTORS
 
- --------------------------------------------------------------------------------
 
ILLIQUID SECURITIES
The  Government  Income  Fund  may invest  up  to  10% of  its  total  assets in
securities the  disposition of  which may  be subject  to legal  or  contractual
restrictions or the markets for which may be illiquid. The Strategic Income Fund
and  the  Portfolio  each  may  invest  up to  15%  of  net  assets  in illiquid
securities. Securities may  be considered illiquid  if a Fund  or the  Portfolio
cannot  reasonably expect within seven days  to receive approximately the amount
at which the Fund or the Portfolio values such securities. The sale of  illiquid
securities,  if they can  be sold at  all, generally will  require more time and
result in  higher  brokerage  charges  or dealer  discounts  and  other  selling
expenses  than will the  sale of liquid securities,  such as securities eligible
for trading on  U.S. securities  exchanges or in  the over-the-counter  markets.
Moreover,  restricted securities,  which may  be illiquid  for purposes  of this
limitation often sell, if at all, at a price lower than similar securities  that
are not subject to restrictions on resale.
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, each Fund  and the Portfolio may  be obligated to pay
all or part of  the registration expenses and  a considerable period may  elapse
between  the time of the decision  to sell and the time  a Fund or the Portfolio
may be permitted to sell a  security under an effective registration  statement.
If,  during such a period, adverse market  conditions were to develop, a Fund or
the Portfolio might obtain a less favorable price than prevailed when it decided
to sell.
 
Not  all  restricted  securities   are  illiquid.  In   recent  years  a   large
institutional   market  has  developed  for  certain  securities  that  are  not
registered under the Securities Act of 1933, as amended ("1933 Act"),  including
private  placements, repurchase agreements, commercial paper, foreign securities
and corporate bonds and notes. These instruments are often restricted securities
because the  securities are  sold in  transactions not  requiring  registration.
Institutional investors generally will not seek to sell these instruments to the
general   public,  but  instead  will  often   depend  either  on  an  efficient
institutional market in which such unregistered securities can be readily resold
or on an issuer's ability to honor  a demand for repayment. Therefore, the  fact
that there are contractual or legal restrictions on resale to the general public
or certain institutions is not dispositive of the liquidity of such investments.
 
Rule  144A under the 1933 Act establishes  a "safe harbor" from the registration
requirements of the  1933 Act  for resales  of certain  securities to  qualified
institutional  buyers.  Institutional  markets  for  restricted  securities have
developed as a result of Rule 144A, providing both readily ascertainable  values
for  restricted securities and the ability to liquidate an investment to satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance and  settlement of  unregistered securities  of domestic  and  foreign
issuers,  such as  the PORTAL  System sponsored  by the  National Association of
Securities Dealers,  Inc.  An  insufficient number  of  qualified  institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a  Fund or the  Portfolio, however, could affect  adversely the marketability of
such portfolio securities and a Fund or the Portfolio might be unable to dispose
of such securities promptly or at favorable prices.
 
                  Statement of Additional Information Page 15

                             GT GLOBAL INCOME FUNDS
 
With respect  to  liquidity determinations  generally,  the Company's  Board  of
Directors  has  the  ultimate responsibility  for  determining  whether specific
securities, including  restricted securities  eligible for  resale to  qualified
institutional  buyers pursuant to  Rule 144A under  the 1933 Act,  are liquid or
illiquid.  The  Board   has  delegated   the  function   of  making   day-to-day
determinations  of  liquidity  to  the  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 that make  quotes for the security;  (iii)
the  number of dealers  that have undertaken  to make a  market in the security;
(iv) the  number  of other  potential  purchasers; and  (v)  the nature  of  the
security  and  how  trading is  effected  (e.g.,  the time  needed  to  sell the
security, how offers are solicited and  the mechanics of transfer). The  Manager
will monitor the liquidity of securities held by each Fund and the Portfolio and
report  periodically  on such  decisions to  the  Company's Board  of Directors.
Moreover, as noted in the Prospectus, certain securities, such as those  subject
to  repatriation restrictions of more than seven days, will generally be treated
as illiquid.
 
FOREIGN SECURITIES
    POLITICAL, SOCIAL AND  ECONOMIC RISKS. Investing  in securities of  non-U.S.
companies may entail additional risks due to the potential political, social and
economic  instability  of  certain  countries and  the  risks  of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment,  convertibility of currencies into  U.S. dollars and on repatriation
of capital  invested. In  the event  of such  expropriation, nationalization  or
other confiscation by any country, either a Fund or the Portfolio could lose its
entire investment in any such country.
 
    RELIGIOUS,  POLITICAL AND ETHNIC  INSTABILITY. Certain countries  in which a
Fund or the Portfolio may invest may have groups that advocate radical religious
or revolutionary philosophies or support ethnic independence. Any disturbance on
the  part  of  such  individuals  could  carry  the  potential  for   widespread
destruction  or  confiscation  of  property owned  by  individuals  and entities
foreign to such country and could cause the loss of a Fund's or the  Portfolio's
investment  in those  countries. Instability may  also result  from, among other
things: (i) authoritarian governments or  military involvement in political  and
economic    decision-making,   including    changes   in    government   through
extra-constitutional means;  (ii) popular  unrest  associated with  demands  for
improved  political, economic and social conditions; and (iii) hostile relations
with neighboring  or  other  countries.  Such  political,  social  and  economic
instability could disrupt the principal financial markets in which a Fund or the
Portfolio  invests  and  adversely  affect  the  value  of  the  Fund's  or  the
Portfolio's assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity markets, by  foreign entities such as  the Government Income  Fund,
the  Strategic Income Fund or the  Portfolio. These restrictions or controls may
at times limit or preclude investment in certain securities and may increase the
cost and expenses  of a Fund  or the Portfolio.  For example, certain  countries
require prior governmental approval before investments by foreign persons may be
made,  or may limit the amount of  investment by foreign persons in a particular
company, or limit the investment by foreign persons to only a specific class  of
securities of a company that may have less advantageous terms than securities of
the company available for purchase by nationals. Moreover, the national policies
of  certain  countries  may  restrict  investment  opportunities  in  issuers or
industries deemed sensitive to national  interests. In addition, some  countries
require governmental approval for the repatriation of investment income, capital
or  the proceeds of securities sales by foreign investors. In addition, if there
is a deterioration in a  country's balance of payments  or for other reasons,  a
country  may  impose restrictions  on  foreign capital  remittances  abroad. The
Government Income Fund,  the Strategic  Income Fund  or the  Portfolio could  be
adversely   affected  by  delays  in,  or  a  refusal  to  grant,  any  required
governmental approval for repatriation, as well  as by the application to it  of
other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting  principles. Most  of  the foreign  securities held  by  the
Government  Income Fund, the Strategic Income Fund  or the Portfolio will not be
registered with  the SEC  or regulators  of any  foreign country,  nor will  the
issuers thereof be subject to the SEC's reporting requirements. Thus, there will
be less available information concerning most foreign issuers of securities held
by  the Government Income Fund, the Strategic Income Fund and the Portfolio than
is  available  concerning  U.S.  issuers.  In  instances  where  the   financial
statements  of  an issuer  are not  deemed to  reflect accurately  the financial
situation of the issuer, the 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
 
                  Statement of Additional Information Page 16
<PAGE>
                             GT GLOBAL INCOME FUNDS
addition, where public information  is available, it may  be less reliable  than
such  information  regarding  U.S.  issuers. Issuers  of  securities  in foreign
jurisdictions are generally not subject to the same degree of regulation as  are
U.S.   issuers  with  respect   to  such  matters   as  restrictions  on  market
manipulation, insider trading rules,  shareholder proxy requirements and  timely
disclosure of information.
 
    CURRENCY  FLUCTUATIONS. Because  the Funds  and the  Portfolio, under normal
circumstances, will invest  substantial portions  of their total  assets in  the
securities  of foreign issuers which are  denominated in foreign currencies, the
strength or weakness  of the U.S.  dollar against such  foreign currencies  will
account  for part of  each Fund's and the  Portfolio's investment performance. A
decline in the  value of any  particular currency against  the U.S. dollar  will
cause  a decline  in the U.S.  dollar value  of each Fund's  and the Portfolio's
holdings of securities  and cash  denominated in such  currency and,  therefore,
will  cause an overall decline in their  respective net asset values and any net
investment  income  and  capital  gains  derived  from  such  securities  to  be
distributed in U.S. dollars to shareholders of the Funds. Moreover, if the value
of  the foreign currencies in which a  Fund or the Portfolio receives its income
declines relative to the U.S. dollar between  the receipt of the income and  the
making  of Fund  distributions, the  Fund or  the Portfolio  may be  required to
liquidate securities in order to make distributions if the Fund or the Portfolio
has insufficient cash in U.S. dollars to meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors including  the supply and  demand for particular currencies,
central bank efforts to support particular currencies, the relative movement  of
interest  rates, and pace of  business activity in the  other countries, and the
United States, and other economic  and financial conditions affecting the  world
economy.
 
Although  the Funds and the Portfolio value  their assets daily in terms of U.S.
dollars, they do not intend to convert holdings of foreign currencies into  U.S.
dollars  on a daily basis. The  Funds and the Portfolio will  do so from time to
time, and  investors  should be  aware  of  the costs  of  currency  conversion.
Although  foreign exchange dealers do  not charge a fee  for conversion, they do
realize a profit based on the difference ("spread") between the prices at  which
they are buying and selling various currencies. Thus, a dealer may offer to sell
a  foreign currency  to a  Fund at  one rate,  while offering  a lesser  rate of
exchange should the Fund desire to sell that currency to the dealer.
 
    ADVERSE MARKET CHARACTERISTICS.  Securities of many  foreign issuers may  be
less  liquid and their  prices more volatile than  securities of comparable U.S.
issuers. In  addition,  foreign securities  markets  and brokers  generally  are
subject  to less governmental  supervision and regulation than  in the U.S., and
foreign securities transactions usually are subject to fixed commissions,  which
generally  are  higher  than  negotiated commissions  on  U.S.  transactions. In
addition,  foreign  securities  transactions  may  be  subject  to  difficulties
associated  with the settlement of such transactions. Delays in settlement could
result in  temporary  periods  when  assets  of a  Fund  or  the  Portfolio  are
uninvested  and no  return is  earned thereon.  The inability  of a  Fund or the
Portfolio to make intended security  purchases due to settlement problems  could
cause  it to miss attractive opportunities.  Inability to dispose of a portfolio
security due to settlement problems either could  result in losses to a Fund  or
the  Portfolio due to subsequent declines in value of the portfolio security or,
if the Fund or the Portfolio has  entered into a contract to sell the  security,
could  result in possible liability to  the purchaser. The Manager will consider
such difficulties  when  determining  the  allocation  of  each  Fund's  or  the
Portfolio's assets, although the Manager does not believe that such difficulties
will  have a material adverse effect on  the Funds' or the Portfolio's portfolio
trading activities.
 
The Funds and the Portfolio may use foreign custodians, which may involve  risks
in  addition to those related to the  use of U.S. custodians. Such risks include
uncertainties  relating  to:  (i)  determining  and  monitoring  the   financial
strength,  reputation and  standing of  the foreign  custodian; (ii) maintaining
appropriate safeguards to protect the Funds' and the Portfolio's investments and
(iii) possible difficulties  in obtaining and  enforcing judgments against  such
custodians.
 
    WITHHOLDING  TAXES. Each  Fund's and  the Portfolio's  net investment income
from foreign issuers may be subject to withholding taxes by the foreign issuer's
country, thereby reducing the Fund's  and the Portfolio's net investment  income
or  delaying the  receipt of  income where  those taxes  may be  recaptured. See
"Taxes."
 
    CONCENTRATION. To the  extent a Fund  invests a significant  portion of  its
assets in securities of issuers located in a particular country or region of the
world, such Portfolio may be subject to greater risks and may experience greater
volatility than a fund that is more broadly diversified geographically.
 
    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Belgium,
Denmark,  France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg, Netherlands,
Portugal, Spain, and the United  Kingdom) eliminated certain import tariffs  and
quotas  and  other trade  barriers with  respect  to one  another over  the past
several years. The Manager  believes that this  deregulation should improve  the
prospects  for economic growth  in many Western  European countries. Among other
things, the deregulation could enable
 
                  Statement of Additional Information Page 17
<PAGE>
                             GT GLOBAL INCOME FUNDS
companies domiciled in  one country  to avail  themselves of  lower labor  costs
existing  in  other  countries.  In addition,  this  deregulation  could benefit
companies domiciled in one country by opening additional markets for their goods
and services in other countries. Since, however, it is not clear what the  exact
form  or effect of  these Common Market  reforms will be  on business in Western
Europe, it is impossible to predict  the long-term impact of the  implementation
of these programs on the securities owned by a Fund.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  RUSSIA AND  EASTERN  EUROPEAN COUNTRIES.
Investing in Russia  and Eastern European  countries involves a  high degree  of
risk  and special considerations not typically  associated with investing in the
United States securities markets, and  should be considered highly  speculative.
Such  risks include: (1)  delays in settling portfolio  transactions and risk of
loss arising out of the system of  share registration and custody; (2) the  risk
that  it may be impossible  or more difficult than  in other countries to obtain
and/or enforce a  judgement; (3) pervasiveness  of corruption and  crime in  the
economic system; (4) currency exchange rate volatility and the lack of available
currency  hedging instruments; (5) higher rates of inflation (including the risk
of  social  unrest  associated  with   periods  of  hyper-inflation)  and   high
unemployment; (6) controls on foreign investment and local practices disfavoring
foreign  investors and limitations on  repatriation of invested capital, profits
and dividends, and  on a fund's  ability to exchange  local currencies for  U.S.
dollars;  (7) political instability and social unrest and violence; (8) the risk
that the governments of Russia and Eastern European countries may decide not  to
continue  to support the economic reform programs implemented recently and could
follow radically different political and/or  economic policies to the  detriment
of  investors,  including non-market-oriented  policies such  as the  support of
certain industries at the expense of other sectors or investors, or a return  to
the  centrally planned economy that existed  when such countries had a communist
form of government; (9) the financial condition of companies in these countries,
including large amounts of inter-company debt which may create a payments crisis
on a national scale; (10) dependency on exports and the corresponding importance
of international trade;  (11) the risk  that the tax  system in these  countries
will  not  be reformed  to prevent  inconsistent, retroactive  and/or exorbitant
taxation; and (12) the underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly since 1990. The general government position has deteriorated as  a
result  of weakening economic  growth and stimulative  measures taken to support
economic activity and to  restore financial stability.  Although the decline  in
interest   rates  and  fiscal  stimulation   packages  have  helped  to  contain
recessionary forces, uncertainties remain. Japan is also heavily dependent  upon
international  trade, so its  economy is especially  sensitive to trade barriers
and disputes.  Japan has  had  difficult relations  with its  trading  partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible  that  trade sanctions  and other  protectionist measures  could impact
Japan adversely in both the short and the long term.
 
The common  stocks  of many  Japanese  companies trade  at  high  price-earnings
ratios.  Differences  in accounting  methods make  it  difficult to  compare the
earnings of  Japanese companies  with  those of  companies in  other  countries,
especially  in the  U.S. In  general, however, reported  net income  in Japan is
understated relative to  U.S. accounting standards  and this is  one reason  why
price-earnings   ratios  of  the  stocks   of  Japanese  companies  have  tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally  been lower than  in the  U.S., both  of
which  factors tend to result in  lower discount rates and higher price-earnings
ratios in Japan than in the U.S.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes  also exist  between  South Korea  and North  Korea.  In
addition,  the  Funds  may  invest  in  Hong  Kong,  which  reverted  to Chinese
Administration on  July 1,  1997. Investments  in Hong  Kong may  be subject  to
expropriation,  national, nationalization or confiscation,  in which case a Fund
could lose its  entire investment in  Hong Kong. In  addition, the reversion  of
Hong  Kong also presents a risk that the Hong Kong dollar will be devalued and a
risk of possible  loss of  investor confidence  in Hong  Kong's currency,  stock
market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies and securities markets of certain Latin
 
                  Statement of Additional Information Page 18
<PAGE>
                             GT GLOBAL INCOME FUNDS
American  countries. Certain Latin American countries are also among the largest
debtors to  commercial banks  and foreign  governments. At  times certain  Latin
American  countries have declared  moratoria on the  payment of principal and/or
interest on  external  debt.  In addition,  certain  Latin  American  securities
markets have experienced high volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL CONSIDERATIONS AFFECTING EMERGING MARKETS. The Strategic Income Fund
and the Portfolio may invest in  debt securities in emerging markets.  Investing
in  securities in emerging countries may  entail greater risks than investing in
debt securities in  developed countries.  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  Strategic  Income  Fund's  and the
Portfolio's investment opportunities,  including restrictions  on investment  in
issuers  or  industries deemed  sensitive  to national  interests;  (iv) foreign
taxation; and  (v) the  absence  of developed  structures governing  private  or
foreign  investment  or  allowing for  judicial  redress for  injury  to private
property.
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in  more developed markets.  In such  emerging securities markets
there may be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economies  and securities
markets of certain emerging market countries.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
Each Fund and the Portfolio has adopted the following investment limitations  as
fundamental policies which may not be changed without approval by the holders of
the lesser of (i) 67% of that Fund's shares or the total beneficial interests of
the Portfolio represented at a meeting at which more than 50% of the outstanding
shares  of  the Fund  or the  total  beneficial interests  of the  Portfolio are
represented, or (ii) more than 50% of the outstanding shares of the Fund or  the
total  beneficial interests of  the Portfolio. Whenever the  High Income Fund is
requested to vote on  a change in the  investment limitations of the  Portfolio,
the  Fund will  hold a meeting  of its shareholders  and will cast  its votes as
instructed by its shareholders.
 
                             GOVERNMENT INCOME FUND
 
The Government Income Fund may not:
 
        (1) Invest  25%  or  more of  the  value  of its  total  assets  in  the
    securities  of issuers conducting their principal business activities in the
    same industry, except  that this  limitation shall not  apply to  securities
    issued  or guaranteed as to principal and interest by the U.S. Government or
    any of its agencies or instrumentalities;
 
        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;
 
        (3) Buy or sell real estate (including real estate limited partnerships)
    or  commodities or commodity contracts; however, the Fund may invest in debt
    securities secured  by  real  estate  or  interests  therein  or  issued  by
    companies  which invest in real estate  or interests therein, including real
    estate investment trusts,  and may  purchase or  sell currencies  (including
    forward  currency exchange contracts), futures contracts and related options
    generally as described in  the Prospectus and  this Statement of  Additional
    Information and subject to (14) below;
 
        (4)  Acquire  securities  subject  to  restrictions  on  disposition  or
    securities for which  there is no  readily available market,  or enter  into
    repurchase  agreements or purchase time deposits maturing in more than seven
    days, or purchase OTC options or hold assets set aside to cover OTC  options
    written  by a Fund, if, immediately after and as a result, the value of such
    securities would exceed, in the aggregate, 10% of the Fund's total assets;
 
        (5) Engage in the business of underwriting securities of other  issuers,
    except  to  the  extent that  the  disposal  of an  investment  position may
    technically cause it to be considered an underwriter as that term is defined
    under the 1933 Act;
 
        (6) Make loans, except  that the Fund may  purchase debt securities  and
    enter into repurchase agreements and make loans of portfolio securities;
 
        (7)   Sell  securities  short,  except  to  the  extent  that  the  Fund

    connection with futures contracts subject to (14) below;
 
        (9) Borrow money, except from banks for temporary or emergency  purposes
    not  in excess of 30% of the value of the Fund's total assets. The Fund will
    not  purchase  securities  while  such  borrowings  are  outstanding.   This
    restriction shall not prevent the Fund from entering into reverse repurchase
    agreements  and  engaging  in  "roll"  transactions,  provided  that reverse
    repurchase  agreements,  "roll"  transactions  and  any  other  transactions
    constituting  borrowing by the  Fund may not exceed  one-third of the Fund's
    total assets. In the event that the asset coverage for the Fund's borrowings
    falls below 300%, the Fund will reduce, within three days (excluding Sundays
    and holidays), the amount of its borrowings in order to provide for the 300%
    asset coverage;

    of such issuer, together own more than 5% of the securities of such  issuer;
    or
 
       (14) Enter into a futures contract, if, as a result thereof, more than 5%
    of  the Fund's total assets  (taken at market value  at the time of entering
    into the contract) would be committed to margin on such futures contracts.
 
For purposes  of the  Fund's concentration  policy contained  in limitation  (1)
above,  the Fund intends to comply with  the SEC staff positions that securities
issued or  guaranteed  as  to  principal and  interest  by  any  single  foreign
government or any supranational organizations in the aggregate are considered to
be securities of issuers in the same industry.
 
   
The  following  investment  policies  of  the  Government  Income  Fund  are not
fundamental policies  and may  be changed  by  vote of  the Company's  Board  of
Directors  without shareholder approval.  The Fund may not:  (1) borrow money to
purchase securities; and (2) invest in securities of an issuer if the investment
would cause the Fund to own more than 10% of any class of securities of any  one
issuer.

        (1)  Invest  25%  or  more of  the  value  of its  total  assets  in the

    investable  assets  in  an  open-end  management  investment  company   with
    substantially  the same  investment objectives, policies  and limitations as
    the Fund) except that this limitation  shall not apply to securities  issued
    or  guaranteed as to principal and interest by the U.S. Government or any of
    its agencies or instrumentalities;

    estate  investment trusts,  and may  purchase or  sell currencies (including
    forward currency exchange contracts), futures contracts and related  options
    generally  as described in  the Prospectus and  this Statement of Additional
    Information and subject to (13) below;

    connection with futures contracts subject to (13) below;
 
        (8)  Borrow  money in  excess  of 33  1/3%  of the  Fund's  total assets
    (including the  amount  borrowed),  less all  liabilities  and  indebtedness
    (other  than borrowing).  This restriction shall  not prevent  the Fund from
    entering  into  reverse  repurchase   agreements  and  engaging  in   "roll"
    transactions,   provided   that   reverse   repurchase   agreements,  "roll"
    transactions and any other transactions  constituting borrowing by the  Fund
    may  not exceed one-third of the Fund's  total assets. In the event that the
    asset coverage for  the Fund's borrowings  falls below 300%,  the Fund  will

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
Subject to policies established by the Company's Board of Directors, the Manager
is responsible for the execution of  the Government Income and Strategic  Income
Funds'  and the Portfolio's portfolio transactions  and the selection of broker/
dealers that  execute  such  transactions  on behalf  of  these  Funds  and  the
Portfolio. In executing transactions, the Manager seeks the best net results for
the  Government Income and Strategic Income Funds and the Portfolio, taking into
account such factors as the price (including the applicable brokerage commission
or dealer spread), size  of the order, difficulty  of execution and  operational
facilities of the firm involved. Although the 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  Funds
and  the Portfolio may engage in soft dollar arrangements for research services,
as described below, neither  the Funds nor the  Portfolio has any obligation  to
deal  with  any broker/dealer  or group  of broker/dealers  in the  execution of
portfolio transactions.
 
Debt securities generally are traded  on a "net" basis  with a dealer acting  as
principal for its own account without a stated commission, although the price of
the  security  usually  includes  a  profit  to  the  dealer.  U.S.  and foreign
government securities and money market  instruments generally are traded in  the
OTC  markets. In underwritten  offerings, securities usually  are purchased at a
fixed price which  includes an  amount of  compensation to  the underwriter.  On
occasion,  securities may be purchased directly from an issuer, in which case no
commissions or discounts  are paid.  Broker/dealers may  receive commissions  on
futures, currency and options transactions.
 
Consistent  with the interests of  the Funds and the  Portfolio, the Manager may
select brokers to execute the Funds' and the Portfolio's portfolio  transactions
on  the basis of the research and brokerage services they provide to the Manager
for its use  in managing  the Funds  and the  Portfolio and  its other  advisory
accounts. Such services may include furnishing analyses, reports and information
concerning issuers, industries, securities, geographic regions, economic factors
and  trends,  portfolio strategy,  and  performance of  accounts;  and effecting
securities transactions  and performing  functions incidental  thereto (such  as
clearance  and settlement). Research  and brokerage services  received from such
brokers are in  addition to, and  not in lieu  of, the services  required to  be
performed   by  the  Manager  under  investment  management  and  administration
contracts. A  commission paid  to such  brokers may  be higher  than that  which
another  qualified broker would have charged for effecting the same transaction,
provided that  the 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  Funds and  the Portfolio  and its  other
clients  and that the total commissions paid by the Funds and the Portfolio will
be reasonable  in  relation  to the  benefits  received  by the  Funds  and  the
Portfolio  over  the long  term.  Research services  may  also be  received from
dealers who execute Fund transactions in OTC markets.
 
The 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 Funds or the Portfolio toward payment of the  Funds'
or the Portfolio's expenses, such as transfer agent and custodian fees.
 
Investment  decisions for each  Fund and the Portfolio  and for other investment
accounts managed by the 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 one  or both  Funds and the
Portfolio. In  such cases,  simultaneous transactions  may occur.  Purchases  or
sales  are then  allocated as  to price or  amount in  a manner  deemed fair and
equitable to all accounts involved. While in some cases this practice could have
a detrimental effect upon the price or value of the security as far as the Funds
and the  Portfolio are  concerned,  in other  cases  the Manager  believes  that
coordination  and  the ability  to participate  in  volume transactions  will be
beneficial to the Funds and the Portfolio.
 
Under a policy adopted by the  Company's Board of Directors and the  Portfolio's
Board  of Trustees, 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 Funds  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 Funds and such other funds.

                             GT GLOBAL INCOME FUNDS
 
Each  Fund  and  the  Portfolio  contemplates  purchasing  most  foreign  equity
securities  in  over-the-counter  markets  or  stock  exchanges  located  in the
countries in  which the  respective  principal offices  of  the issuers  of  the
various  securities are located, if that is the best available market. The fixed
commissions paid  in  connection  with  most  such  foreign  stock  transactions
generally  are higher than negotiated commissions on United States transactions.
There generally is less government  supervision and regulation of foreign  stock
exchanges  and brokers than  in the United  States. Foreign security settlements
may  in  some  instances  be  subject  to  delays  and  related   administrative
uncertainties.
 
Foreign equity securities may be held by a Fund and the Portfolio in the form of
American  Depository  Receipts  ("ADRs"), American  Depository  Shares ("ADSs"),
Continental  Depository  Receipts  ("CDRs")  or  European  Depository   Receipts
("EDRs")  or securities convertible into  foreign equity securities. ADRs, ADSs,
CDRs and EDRs may be listed on stock exchanges, or traded in the OTC markets  in
the  United States or  Europe, as the  case may be.  ADRs, like other securities
traded in the United States, will be subject to negotiated commission rates. The
foreign and domestic debt securities and  money market instruments in which  the
Funds and the Portfolio may invest generally are traded in the OTC markets.
 
   
The  Funds and  the Portfolio  contemplate that,  consistent with  the policy of
obtaining the best net results, brokerage transactions may be conducted  through
certain  companies  that  are members  of  the Liechtenstein  Global  Trust. The
Company's Board  of Directors  has adopted  procedures in  conformity with  Rule
17e-1  under the 1940 Act to ensure  that all brokerage commissions paid to such
affiliates are reasonable and fair  in the context of  the market in which  they
are  operating. Any such transactions will  be effected and related compensation
paid only in accordance  with applicable SEC regulations.  For the fiscal  years
ended  October 31, 1997,  1996 and 1995, the  Portfolio paid aggregate brokerage
commissions of $0,  $86,600 and  $0, respectively.  For the  fiscal years  ended
October  31,  1997, 1996  and 1995,  the Government  Income Fund  paid aggregate
brokerage commissions of $4,987,  $24,663 and $0,  respectively. For the  fiscal
years  ended October  31, 1997,  1996 and 1995,  the Strategic  Income Fund paid
aggregate brokerage commissions of $6,177, $85,404 and $0, respectively.
    
 
PORTFOLIO TRADING AND TURNOVER
Each Fund  and the  Portfolio  engages in  portfolio  trading when  the  Manager
concludes  that the sale of a security owned  by a Fund and the Portfolio and/or
the purchase of another  security of better value  can enhance principal  and/or
increase  income. A  security may  be sold to  avoid any  prospective decline in
market value, or a security may be  purchased in anticipation of a market  rise.
Consistent  with  each  Fund's  and  the  Portfolio's  investment  objectives, a
security also may be sold and a comparable security purchased coincidentally  in
order  to take  advantage of what  is believed to  be a disparity  in the normal
yield and price relationship between the two securities. Although the Funds  and
the  Portfolio  generally do  not intend  to trade  for short-term  profits, the
securities in each Fund's  and the Portfolio's portfolio  will be sold  whenever
the Manager believes it is appropriate to do so, without regard to the length of
time  a particular security may have been held. Portfolio turnover is calculated
by dividing the  lesser of sales  or purchases of  portfolio securities by  each
Fund's   or  the  Portfolio's  average   month-end  portfolio  value,  excluding
short-term  investments.  Higher  portfolio  turnover  involves  correspondingly
greater  brokerage commissions  and other transaction  costs that a  Fund or the
Portfolio will bear directly, and could result in the realization of net capital
gains that  would be  taxable when  distributed to  shareholders. The  portfolio
turnover  rates for  the Government Income  Fund, Strategic Income  Fund and the
Portfolio the last two fiscal years were as follows:

INVESTMENT MANAGEMENT AND ADMINISTRATION SERVICES
The  Manager serves  as the  Government Income  Fund's and  the Strategic Income
Fund's investment manager and administrator  under an Investment Management  and
Administration Contract between the Company and the Manager ("Company Management
Contract")  and as the Portfolio's investment manager and administrator under an
Investment Management and Administration Contract between the Portfolio and  the
Manager    ("Portfolio   Management    Contract")   (collectively,   "Management
Contracts"). The Manager serves as the High Income Fund's administrator under an
Administration Contract ("Administration Contract") between the Company and  the
Manager. The Administration Contract will not be deemed an advisory contract, as
defined under the 1940 Act. As investment manager and administrator, the Manager
makes  all investment  decisions for the  Government Income  Fund, the Strategic
Income Fund and the Portfolio and as administrator, the Manager administers each
Fund's and the Portfolio'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, the  Funds,  and the  Portfolio  and provides  suitable  office  space,
necessary  small  office  equipment  and  utilities.  For  these  services,  the
Government Income  Fund and  the  Strategic Income  Fund  each pay  the  Manager
investment management and administration fees, based on the Funds' average daily
net  assets computed daily and paid monthly,  at the annualized rate of .725% on
the first  $500 million,  .70% on  the  next 1  billion, .675%  on the  next  $1
billion,   and  .65%   on  amounts  thereafter.   The  High   Income  Fund  pays
administration fees, computed  daily and  paid monthly,  to the  Manager at  the
annualized  rate of 0.25% of  the Fund's average daily  net assets. In addition,
the High Income Fund bears a pro  rata portion of the investment management  and
administration fee paid by the Portfolio to the Manager. The Portfolio pays such
fees,  also computed daily and  paid monthly at the  annualized rate of .475% on
the first  $500 million,  .45% on  the next  $1 billion,  .425% on  the next  $1
billion, and .40% on amounts thereafter of its average daily net assets, plus 2%
of  the  Portfolio's  total  investment  income  as  stated  in  the Portfolio's
Statement of  Operations,  calculated  in  accordance  with  generally  accepted
accounting  principles, adjusted daily for currency revaluations, on a marked to
market basis,  of the  Portfolio's assets;  provided, however,  that during  any
fiscal  year this amount shall not exceed 2% of the Portfolio's total investment
income calculated in accordance with generally accepted accounting principles.
 
The Management Contracts may  be renewed for one-year  terms, provided that  any
such  renewal  has been  specifically  approved at  least  annually by:  (i) the
Company's  Board  of  Directors  or  the  Portfolio's  Board  of  Trustees,   as
applicable,  or  by the  vote of  a majority  of the  Fund's or  the Portfolio's
outstanding voting securities (as defined in the 1940 Act), and (ii) a  majority
of  Directors or Trustees who are not  parties to the Management Contract or the
Administration Contract,  as applicable,  or "interested  persons" of  any  such
party  (as defined in the 1940 Act), cast  in person at a meeting called for the
specific purpose of voting  on such approval.  The Management Contracts  provide
that  with respect to the Government Income  Fund, the Strategic Income Fund and
the Portfolio, and the Administration Contract provides that with respect to the
High Income Fund, either the Company, the Portfolio or the Manager may terminate
the Contract without penalty upon sixty days' written notice to the other party.
The Management Contracts and the Administration Contract terminate automatically
in the event of their assignment (as defined in the 1940 Act).

DISTRIBUTION SERVICES
Each  Fund's Class A  and Class B  shares are offered  continuously through each
Fund's principal underwriter  and distributor,  GT Global, on  a "best  efforts"
basis  pursuant to  separate Distribution Contracts  between the  Company and GT
Global.
 
As described in the Prospectus, the Company has adopted a separate  Distribution
Plan  for each class of  each Fund in accordance with  Rule 12b-1 under the 1940
Act (each a"Class A  Plan" and "Class B  Plan," respectively, and  collectively,
"Plans"). The rate of payments by each 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 affected  class. All expenses for which  GT
Global  is reimbursed under  a Class A  Plan will have  been incurred within one
year of such reimbursement. The following table discloses payments made by  each
Fund  to GT Global under  the Class A Plan  and the Class B  Plan for the fiscal
year ended October 31, 1997.

In approving the Plans, the Directors determined that the adoption of the  Class
B  Plan or  continuation of  the Class A  Plan, as  applicable, was  in the best
interests of the shareholders of the Funds. Agreements related to the Plans also
must be approved  by such vote  of the  Directors, including a  majority of  the
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 will  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  Funds,  retains certain  amounts  of such  charges  and
reallows other amounts of such charges to broker/dealers who sell shares.

TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The Transfer  Agent  has been  retained  by  the Funds  to  perform  shareholder
servicing,  reporting and general  transfer agent functions  for them. 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  each Fund, for its out-of-pocket expenses
for such  items as  postage,  forms, telephone  charges, stationery  and  office
supplies.  The Manager also serves as  each Fund's pricing and accounting agent.
As of October 31,  1997, October 31,  1996 and October 31,  1995, the Fund  paid
accounting  services fees  to the Manager  of Government  Income Fund, Strategic
Income Fund  and  High Income  Fund  $85,149, $127,205  and  $40,218;  $123,309,
$131,517 and $34,980; and $116,607, $101,697 and $22,563, respectively.
    
 
EXPENSES OF THE FUNDS AND THE PORTFOLIO
Each  Fund and the  Portfolio 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 agent 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 by the Funds and other funds organized as

series of the Company are allocated on a basis deemed fair and equitable,  which
may  be based  on the  relative net  assets of  the Funds  or the  nature of the
services performed  and  relative  applicability  to  each  Fund.  Expenditures,
including  costs incurred in  connection with the purchase  or sale of portfolio
securities,  which  are  capitalized  in  accordance  with  generally   accepted
accounting  principles applicable to investment  companies, are accounted for as
capital items and not as expenses. The ratio of each Fund's and the  Portfolio's
expenses  to  its relative  net assets  can be  expected to  be higher  than the
expense ratios of funds investing solely in domestic securities, since the  cost
of  maintaining the  custody of  foreign securities  and the  rate of investment
management fees paid by  each Fund and the  Portfolio generally are higher  than
the comparable expenses of such other funds.
 
- --------------------------------------------------------------------------------
 
                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
As  described in the Prospectus, each 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  business
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.
 
Each Fund's and the Portfolio's portfolio securities and other assets are valued
as follows:
 
Equity  securities, including  ADRs, ADSs  and EDRs,  which are  traded on stock
exchanges are valued at the last sale price on the exchange or in the  principal
over-the-counter  market in which such securities are traded, as of the close of
business on the day the  securities are being valued  or, lacking any sales,  at
the  last available bid price. In cases where securities are 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
or 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 debt 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 a  Fund  or the
Portfolio 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. When market  quotations for futures and
options on futures held by a Fund or the Portfolio are readily available,  those
positions will be valued based upon such quotations.
 
Securities  and  other  assets  for  which  market  quotations  are  not readily
available (including restricted securities which  are subject to limitations  as
to  their sale) are valued at fair value as determined in good faith by or under
the direction  of the  Company's Board  of Directors.  The valuation  procedures
applied  in any specific instance are likely to vary from case to case. However,
consideration is generally  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 are generally 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 a Fund's  or the Portfolio's total assets.
The Fund's or the Portfolio's liabilities, including accruals for expenses,  are
deducted  from  its  total assets.  Once  the total  value  of a  Fund's  or the
Portfolio'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.
 
                  Statement of Additional Information Page 31
<PAGE>
                             GT GLOBAL INCOME FUNDS
 
Any  assets or liabilities initially denominated  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. Consequently, the  calculation of the  Funds' respective  net
asset   values  therefore  may   not  take  place   contemporaneously  with  the
determination of the prices  of securities held by  the Funds. 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 Funds' net  asset values 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, a 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 of a Fund 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 a  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 that Fund for  the loss incurred. Investors
whose purchase orders have  been cancelled due to  nonpayment may be  prohibited
from placing future orders.
 
Each  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 a 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, each Fund reserves the right to reject any offer for a purchase of
shares by any individual.
 
SALES OUTSIDE THE UNITED STATES
Sales of Fund shares made through brokers  outside the United States will be  at
net  asset value plus a sales commission,  if any, established by that broker or
by local law.  Such a commission,  if any, may  be more or  less than the  sales
charges listed in the sales charge table included in the Prospectuses.
 
AUTOMATIC INVESTMENT PLAN -- CLASS A SHARES AND CLASS B SHARES
To  establish  participation  in  a Fund's  Automatic  Investment  Plan ("AIP"),
investors or their broker/dealers should specify whether the 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
provided  at the back of the Funds' 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 designated 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 a 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 a Fund upon thirty days' written  notice or by the participant, at any
time, without penalty, upon written notice to the pertinent Fund or the Transfer
Agent.
 
LETTER OF INTENT -- CLASS A SHARES
   
A Letter of Intent ("LOI") is not a binding obligation to purchase the indicated
amount. While Class A shares are held  in escrow under an LOI to ensure  payment
of  applicable sales charges if  the indicated amount is  not met, all dividends
and other distributions on the escrowed shares will be reinvested in  additional
Class A shares or paid in cash, as specified by the shareholder. If the intended
investment  is  not completed  within the  specified thirteen-month  period, the
purchaser must  remit to  GT  Global the  difference  between the  sales  charge
actually  paid and the sales charge that would have been applicable if the total
Class A purchases had been made at a single time. If this amount is not paid  to
GT  Global within twenty  days after written request,  the appropriate number of
escrowed shares will be redeemed and the proceeds paid to GT Global.
    
 
A registered investment adviser,  trust company or  trust department seeking  to
execute  an LOI  as a single  purchaser with  respect to accounts  over which it
exercises investment discretion is required  to provide the Transfer Agent  with
information establishing that it has discretionary authority with respect to the
money  invested (e.g., by providing a  copy of the 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  of a  Fund  may  be purchased  as  the underlying
investment for an IRA meeting the  requirements of sections 408(a), 408A or  530
of  the  Internal Revenue  Code of  1986, as  amended ("Code"),  as well  as for
qualified retirement plans described in Code Section 401 and custodial  accounts
complying with Code Section 403(b)(7).
 
IRAS: If you have earned income from employment (including self-employment), you
can  contribute each year to an IRA up  to the lesser of (1) $2,000 for yourself
or $4,000  for  you  and your  spouse,  regardless  of whether  your  spouse  is
employed,  or (2) 100% of compensation. Some  individuals may be able to take an
income tax deduction for the contribution. Regular contributions may not be made
for the year  you become 70  1/2 or  thereafter. Unless your  and your  spouse's
earnings  exceed  a certain  level, you  also may  establish an  "education IRA"
and/or a  "Roth IRA."  Although contributions  to these  new types  of IRAs  are
nondeductible,   withdrawals   from  them   will   be  tax-free   under  certain
circumstances. Please  consult  your  tax  adviser  for  more  information.  IRA
applications are available from brokers or GT Global.
 
ROLLOVER  IRAS: Individuals who receive  distributions from qualified retirement
plans (other than  required distributions) and  who wish to  keep their  savings
growing  tax-deferred  can  roll  over  (or make  a  direct  transfer  of) their
distribution to a  Rollover IRA. These  accounts can also  receive rollovers  or
transfers  from an existing  IRA. If an "eligible  rollover distribution" from a
qualified employer-sponsored retirement plan is  not directly rolled over to  an
IRA  (or  certain qualified  plans),  withholding at  the  rate of  20%  will be
required for federal income tax purposes.  A distribution from a qualified  plan
that  is not an "eligible rollover  distribution," including a distribution that
is one of series of substantially equal periodic payments, generally is  subject
to  regular wage withholding or withholding at the rate of 10% (depending on the
type and  amount  of  the  distribution),  unless you  elect  not  to  have  any
withholding apply. Please consult your tax adviser for more information.
 
SEP-IRAS:  Simplified  employee  pension plans  ("SEPs"  or  "SEP-IRAs") provide
self-employed individuals (and any eligible employees) with benefits similar  to
Keogh  plans (I.E., self-employed  individual retirement plans)  or Code Section
401(k)  plans,  but  with   fewer  administrative  requirements  and   therefore
potentially lower annual administration expenses.
 
CODE  SECTION 403(B)(7) CUSTODIAL ACCOUNTS: Employees of public schools and most
other tax-exempt organizations can  make pre-tax salary reduction  contributions
to these accounts.
 
PROFIT-SHARING   (INCLUDING   SECTION   401(K))  AND   MONEY   PURCHASE  PENSION
PLANS: Corporations  and other  employers can  sponsor these  qualified  defined
contribution  plans  for  their employees.  A  Section  401(k) plan,  a  type of
profit-sharing plan, additionally permits the eligible, participating  employees
to  make  pre-tax salary  reduction  contributions to  the  plan (up  to certain
limits).
 
SIMPLE PLANS: Employers  with no more  than 100 employees  that do not  maintain
another  retirement  plan  may  establish a  Savings  Incentive  Match  Plan for
Employees ("SIMPLE") either  as separate  IRAs or as  part of  a Section  401(k)

plan.  SIMPLEs are not  subject to the  complicated nondiscrimination rules that
generally apply to qualified retirement plans.
 
EXCHANGES BETWEEN FUNDS
Shares of a 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' prior  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 affixed.  All
shareholders  may request that  redemption proceeds be  transmitted by bank wire
directly to  the  shareholder's predesignated  account  at a  domestic  bank  or
savings institution, if the proceeds are at least $500. Costs in connection with
the  administration of this service, including wire charges, currently are borne
by the  appropriate Fund.  Proceeds of  less than  $500 will  be mailed  to  the
shareholder's  registered address  of record. The  Funds 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  of a Fund 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  Prospectuses). A
corporation (or  partnership) also  must submit  a "Corporation  Resolution"  or
"Certificate  of Partnership" indicating the names, titles and signatures of the
individuals authorized to  act on its  behalf, and the  SWP application must  be
signed by a duly authorized officer(s) and the corporate seal affixed.
 
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 a Fund  upon thirty days' written  notice or by a  shareholder
upon  written notice to a  Fund or the Transfer  Agent. Applications and further
details regarding establishment of a SWP are provided at the back of the  Funds'
Prospectus.
 
SUSPENSION OF REDEMPTION PRIVILEGES
   
The  Funds 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
Funds to dispose of securities owned by them or fairly to determine the value of
their 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 a 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 a  Fund,  so-called
"redemption  in kind." Payments  of redemption 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

<PAGE>
                             GT GLOBAL INCOME FUNDS
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 each 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
a  Fund at the beginning of such period. This election is irrevocable so long as
Rule 18f-1 remains in effect, unless  the SEC by order upon application  permits
the withdrawal of such election.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUNDS
Each  Fund is treated as a separate corporation for federal income tax purposes.
To continue to qualify for treatment  as a regulated investment company  ("RIC")
under  the Code, each Fund must distribute  to its shareholders for each taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income, net short-term capital gain and net gains from certain
foreign  currency  transactions)  ("Distribution  Requirement")  and  must  meet
several  additional requirements. With respect  to each Fund, these requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each taxable year from dividends, interest, payments with respect to  securities
loans  and gains  from the  sale or other  disposition of  securities or foreign
currencies, or other income  (including gains from  options, Futures or  Forward
Contracts)  derived with respect  to its business of  investing in securities or
those currencies ("Income Requirement"); (2) at the close of each quarter of the
Fund's taxable year,  at least  50% of  the value of  its total  assets must  be
represented  by cash and  cash items, U.S.  government securities, securities of
other RICs and other securities, with these other securities limited, in respect
of any one issuer,  to an amount  that does not  exceed 5% of  the value of  the
Fund's  total assets and that  does not represent more  than 10% of the issuer's
outstanding voting  securities; and  (3) at  the close  of each  quarter of  the
Fund's  taxable year, not more than 25% of  the value of its total assets may be
invested in securities (other than U.S. government securities or the  securities
of  other RICs) of any one  issuer. The High Income Fund,  as an investor in the
Portfolio, is deemed to own a proportionate share of the Portfolio's assets, and
to earn  a  proportionate share  of  the  Portfolio's income,  for  purposes  of
determining  whether  that Fund  satisfies the  requirements described  above to
qualify as a RIC.
 
Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent it fails to distribute by the end of any calendar year substantially  all
of  its  ordinary income  for  that year  and capital  gain  net income  for the
one-year period ending on October 31 of that year, plus certain other amounts.
 
See "Taxation of Certain  Investment Activities" below for  a discussion of  the
tax consequences to the High Income Fund of hedging transactions engaged in, and
investments  in passive foreign investment companies ("PFICs") and other foreign
securities by, the Portfolio.
 
TAXATION OF THE PORTFOLIO -- GENERAL
The Portfolio is treated as a partnership for federal income tax purposes and is
not a "publicly traded partnership." As  a result, the Portfolio is not  subject
to  federal income  tax; instead, the  High Income  Fund, as an  investor in the
Portfolio, is required to  take into account in  determining its federal  income
tax liability its share of the Portfolio's income, gains, losses, deductions and
credits,  without regard to whether it  has received any cash distributions from
the Portfolio. The Portfolio also is not subject to New York income or franchise
tax.
 
Because, as noted above, the High Income  Fund is deemed to own a  proportionate
share  of  the Portfolio's  assets, and  to  earn a  proportionate share  of the
Portfolio's income, for purposes of determining whether that Fund satisfies  the
requirements  to  qualify  as  a  RIC,  the  Portfolio  intends  to  conduct its
operations so that the High Income Fund will be able to continue to satisfy  all
those requirements.
 
Distributions  to the High Income Fund from the Portfolio (whether pursuant to a
partial or complete  withdrawal or  otherwise) will  not result  in that  Fund's
recognition of any gain or loss for federal income tax purposes, except that (1)
gain  will be recognized to the extent any cash that is distributed exceeds that
Fund's basis for  its interest  in the  Portfolio before  the distribution,  (2)
income  or gain will be recognized if the distribution is in liquidation of that
Fund's entire interest in the Portfolio and includes a disproportionate share of
any unrealized  receivables  held  by  the  Portfolio,  and  (3)  loss  will  be
recognized  if  a  liquidation  distribution  consists  solely  of  cash  and/or
unrealized receivables. The High Income Fund's basis
 
                  Statement of Additional Information Page 35
<PAGE>
                             GT GLOBAL INCOME FUNDS
for its interest in the  Portfolio generally will equal  the amount of cash  and
the  basis of any property that Fund invests in the Portfolio, increased by that
Fund's share of the Portfolio's  net income and gains  and decreased by (1)  the
amount  of cash and the basis of  any property the Portfolio distributes to that
Fund and (2) that Fund's share of the Portfolio's losses.
 
TAXATION OF CERTAIN INVESTMENT ACTIVITIES
For purposes of the following  discussion, "Investor Fund" means the  Government
Income Fund, the Strategic Income Fund or the Portfolio.
 
   
    FOREIGN  TAXES. Interest  and dividends  received by  an Investor  Fund, and
gains realized thereby,  may be subject  to income, withholding  or other  taxes
imposed  by foreign countries and U.S.  possessions ("foreign taxes") that would
reduce the yield and/or total return on its securities. Tax conventions  between
certain  countries and the United States  may reduce or eliminate foreign taxes,
however, and many  foreign countries  do not impose  taxes on  capital gains  in
respect  of investments by foreign investors. If more than 50% of the value of a
Fund's total assets (taking into account, in  the case of the High Income  Fund,
its  proportionate share of the Portfolio's assets)  at the close of its taxable
year consists of securities of foreign  corporations, the Fund will be  eligible
to, and may, file an election with the Internal Revenue Service that will enable
its  shareholders, in effect, to  receive the benefit of  the foreign tax credit
with respect to any foreign taxes paid  by it (taking into account, in the  case
of  the High Income Fund,  its proportionate share of  any foreign taxes paid by
the Portfolio) (a  "Fund's foreign  taxes"). Pursuant  to the  election, a  Fund
would  treat  those  taxes  as  dividends  paid  to  its  shareholders  and each
shareholder would be required to (1) include in gross income, and treat as  paid
by him, his proportionate share of the Fund's foreign taxes, (2) treat his share
of  those taxes and of any dividend paid  by the Fund that represents its income
from foreign and U.S. possessions sources  (taking into account, in the case  of
the  High Income  Fund, its proportionate  share of the  Portfolio's income from
those sources) as his own  income from those sources  and (3) either deduct  the
taxes  deemed paid by him in computing his taxable income or, alternatively, use
the foregoing  information in  calculating the  foreign tax  credit against  his
federal income tax. Each Fund will report to its shareholders shortly after each
taxable  year their  respective shares  of the  Fund's foreign  taxes and income
(taking into account,  in the case  of the High  Income Fund, its  proportionate
share  of the Portfolio's income) from sources within foreign countries and U.S.
possessions if it makes  this election. Pursuant to  the Taxpayer Relief Act  of
1997  ("Tax Act"),  individuals who  have no  more than  $300 ($600  for married
persons filing jointly) of  creditable foreign taxes included  on Form 1099  and
all  of whose foreign source income is "qualified passive income" may elect each
year to be exempt from the  extremely complicated foreign tax credit  limitation
and  will be  able to  claim a  foreign tax  credit without  having to  file the
detailed Form 1116 that otherwise is required.
    
 
    PASSIVE FOREIGN INVESTMENT COMPANIES. Each  Investor Fund may invest in  the
stock  of PFICs.  A PFIC is  a foreign  corporation -- other  than a "controlled
foreign corporation" (I.E., a  foreign corporation in which,  on any day  during
its  taxable year, more than  50% of the total voting  power of all voting stock
therein or the total value of  all stock therein is owned, directly,  indirectly
or  constructively, by  "U.S. shareholders," defined  as U.S.  persons that own,
directly, indirectly or constructively, at least 10% of that voting power) as to
which the Investor Fund is a U.S. shareholder (effective for their taxable  year
beginning  November 1, 1998) -- that, in  general, meets either of the following
tests: (1) at least 75% of its gross  income is passive or (2) an average of  at
least  50% of  its assets produce,  or are  held for the  production of, passive
income. Under certain circumstances,  a Fund will be  subject to federal  income
tax  on a part (or, in the case of the High Income Fund, its proportionate share
of a part) of any "excess distribution" received  by it (or, in the case of  the
High Income Fund, by the Portfolio) on the stock of a PFIC or of any gain on the
Fund's (or, in the case of the High Income Fund, the Portfolio's) disposition of
that stock (collectively "PFIC income"), plus interest thereon, even if the Fund
distributes  the  PFIC income  as a  taxable dividend  to its  shareholders. The
balance of the  PFIC income will  be included in  the Fund's investment  company
taxable  income and, accordingly, will not be  taxable to the Fund to the extent
it distributes that income to its shareholders.
 
If an  Investor Fund  invests  in a  PFIC and  elects  to treat  the PFIC  as  a
"qualified  electing  fund"  ("QEF"), then  in  lieu  of the  foregoing  tax and
interest obligation, the Investor  Fund (or, in the  case of the Portfolio,  the
High  Income Fund) would be required to include in income each year its pro rata
share  (taking  into  account,  in  the  case  of  the  High  Income  Fund,  its
proportionate  share of  the Portfolio's pro  rata share) of  the QEF's ordinary
earnings and net capital  gain (I.E., the excess  of net long-term capital  gain
over  net  short-term  capital loss)  --  which  most likely  would  have  to be
distributed by the Investor  Fund (or, in  the case of  the Portfolio, the  High
Income Fund) to satisfy the Distribution Requirement and avoid imposition of the
Excise Tax -- even if those earnings and gain were not received thereby from the
QEF.  In most instances  it will be  very difficult, if  not impossible, to make
this election because of certain requirements thereof.
 
Effective for taxable years beginning after 1997, a holder of stock in any  PFIC
may elect to include in ordinary income each taxable year the excess, if any, of
the fair market value of the stock over the adjusted basis therein as of the end
of that
 
                  Statement of Additional Information Page 36
<PAGE>
                             GT GLOBAL INCOME FUNDS
year.  Pursuant to the election, a deduction (as an ordinary, not capital, loss)
also will be allowed for the excess,  if any, of the holder's adjusted basis  in
PFIC  stock over the fair  market value thereof as  of the taxable year-end, but
only to the extent of  any net mark-to-market gains  with respect to that  stock
included  in income for prior  taxable years. The adjusted  basis in each PFIC's
stock subject to the election will be adjusted to reflect the amounts of  income
included  and deductions  taken thereunder.  Regulations proposed  in 1992 would
provide a similar election with respect to the stock of certain PFICs.
 
    OPTIONS, FUTURES AND FOREIGN CURRENCY TRANSACTIONS. The Investors Funds' use
of hedging transactions, such  as selling (writing)  and purchasing options  and
Futures  Contracts and entering  into Forward Contracts,  involves complex rules
that will determine, for federal income tax purposes, the amount, character  and
timing  of recognition  of the  gains and  losses an  Investor Fund  realizes in
connection therewith. Gains from the  disposition of foreign currencies  (except
certain  gains  that may  be  excluded by  future  regulations), and  gains from
options, Futures and Forward Contracts derived by an Investor Fund with  respect
to  its business of investing in  securities or foreign currencies, will qualify
as permissible income under the Income  Requirement for that Investor Fund  (or,
in the case of the Portfolio, the High Income Fund).
 
Futures  and Forward  Contracts that  are subject  to Section  1256 of  the Code
(other  than  those  that  are  part  of  a  "mixed  straddle")  ("Section  1256
Contracts") and that are held by an Investor Fund at the end of its taxable year
generally  will be deemed to  have been sold at  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. Each Investor Fund attempts to monitor section 988 transactions to
minimize any adverse tax impact.
 
If  a Fund  has an  "appreciated financial  position" --  generally, an interest
(including an interest through an option,  Futures or Forward Contract or  short
sale) with respect to any stock, debt instrument (other than "straight debt") or
partnership  interest the fair market value  of which exceeds its adjusted basis
- -- and enters into  a "constructive sale" of  the same or substantially  similar
property,  the Fund will be treated as  having made an actual sale thereof, with
the result  that gain  will be  recognized  at that  time. A  constructive  sale
generally consists of a short sale, an offsetting notional principal contract or
Futures  or Forward Contract entered  into by 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 Strategic Income  Fund and  the Portfolio each  may acquire  zero coupon  or
other  securities issued  with original issue  discount ("OID"). As  a holder of
those securities, that Fund and the Portfolio (and, through it, the High  Income
Fund) each must include in its income the portion of the OID that accrues on the
securities  during the taxable year, even if no corresponding payment on them is
received during the year. Similarly, the Strategic Income Fund and the Portfolio
each must include in  its gross income securities  it receives as "interest"  on
payment-in-kind   securities.  Because   each  Fund   annually  must  distribute
substantially all of its  investment company taxable  income, including any  OID
and  other non-cash  income, to satisfy  the Distribution  Requirement and avoid
imposition of the Excise  Tax, either of  them may be  required in a  particular
year to distribute as a dividend an amount that is greater than the total amount
of cash it actually receives (or, in the case of the High Income Fund, its share
of   the  total  amount   of  cash  the   Portfolio  actually  receives).  Those
distributions will be made from the Fund's  (or, in the case of the High  Income
Fund,  its, or its share of the  Portfolio's) cash assets or, if necessary, from
the proceeds of sales of portfolio  securities. A Fund may (directly or  through
the  Portfolio) realize  capital gains or  losses from those  sales, which would
increase or decrease its  investment company taxable  income and/or net  capital
gain.
 
TAXATION OF THE FUNDS' SHAREHOLDERS
Dividends  and  other  distributions  declared  by a  Fund  in,  and  payable to
shareholders of record as  of a date  in, October, November  or December of  any
year  will  be  deemed  to have  been  paid  by  the Fund  and  received  by the
shareholders on
 
                  Statement of Additional Information Page 37
<PAGE>
                             GT GLOBAL INCOME FUNDS
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  a 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 a Fund (directly or through
the  Portfolio)  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.
 
Dividends paid by a  Fund to a shareholder  who, as to the  United States, is  a
nonresident  alien individual, nonresident alien fiduciary of a trust or estate,
foreign corporation  or foreign  partnership ("foreign  shareholder")  generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding  will not apply, however, to a dividend  paid by a Fund to a foreign
shareholder that is "effectively connected with  the conduct of a U.S. trade  or
business,"  in which case the  reporting and withholding requirements applicable
to domestic shareholders  will apply. A  distribution of net  capital gain by  a
Fund  to a foreign shareholder generally will  be subject to U.S. federal income
tax (at the rates  applicable to domestic persons)  only if the distribution  is
"effectively  connected" or  the foreign  shareholder is  treated as  a resident
alien individual for federal income tax purposes.
 
The foregoing  is a  general  and abbreviated  summary  of certain  federal  tax
considerations  affecting  the  Funds,  their  shareholders  and  the Portfolio.

STANDARDIZED RETURNS
Each 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.

NON-STANDARDIZED RETURNS
In addition  to  Standardized  Returns,  each Fund  also  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 each  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 charges into account.

YIELD
Each  Fund may also include its current yield ("Yield") in advertisements, sales
literature and shareholder  reports. Yield, which  is calculated separately  for
Class  A and Class B shares of each Fund, is computed by dividing the difference
between dividends  and  interest earned  during  a one-month  period  ("a")  and
expenses  accrued for the period (net of reimbursements) ("b") by the product of
the average  daily number  of shares  outstanding during  the period  that  were
entitled  to receive dividends ("c") and the maximum offering price per share on
the last day of the period ("d") according to the following formula as  required
by the Securities and Exchange Commission:

The Yields of the Class A shares of the Strategic Income Fund, Government Income
Fund  and the High Income  Fund for the one-month  period ended October 31, 1996
were 6.58%, 6.23%  and 7.29%, respectively.  The current yields  of the Class  B
shares of Strategic Income Fund, Government Income Fund and High Income Fund for
the  one-month  period  ended October  31,  1996  were 6.23%,  5.87%  and 7.00%,
respectively.
 
IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKETS
Each Fund  and  GT  Global may  from  time  to time,  in  advertisements,  sales
literature and reports furnished to present or prospective shareholders, compare
the Funds 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,
    each Fund  may  be  compared to  its  "peer  group" as  defined  by  Lipper,
    CDA/Wiesenberger,  Morningstar  and/or  other firms,  as  applicable,  or to
    specific funds or  groups of  funds within or  outside of  such peer  group.
    Lipper  generally  ranks  funds  on  the  basis  of  total  return, assuming
    reinvestment of distributions, but does not take sales charges or redemption
    fees into consideration, and is prepared without regard to the consequences.
    In addition  to the  mutual fund  rankings, the  Fund's performance  may  be
    compared  to mutual fund 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.

    World Government Bond Index-Non-U.S., each of  which is a widely used  index
    composed of world government bonds.
 
       (11)  The  World  Bank  Publication  of  Trends  in  Developing Countries
    ("TIDE"), which provides brief reports on most of the World Bank's borrowing
    members. The World  Development Report  is published annually  and looks  at
    global   and  regional  economic  trends  and  their  implications  for  the
    developing economies.

    a  guaranteed rate  of return on  principal, but no  opportunity for capital
    growth. During  a portion  of the  period, the  maximum rates  paid on  some
    savings deposits were fixed by law.

Information  relating  to   foreign  market   performance,  capitalization   and
diversification  is based on sources believed to  be reliable but may be subject
to revision and has not been independently  verified by the Funds or GT  Global.
The  authors  and  publishers of  such  material  are not  to  be  considered as
"experts" under the 1933  Act, on account of  the inclusion of such  information
herein.
 
A  portion of the performance  figures for each market  includes the positive or
negative effects of the currency exchange rates effective at December 31 of each
year between the U.S. dollar and currency of the foreign market (e.g.,  Japanese
Yen,  German Deutschemark  and Hong  Kong Dollar).  A foreign  currency that has
strengthened or weakened against the  U.S. dollar will positively or  negatively
affect the reported returns, as the case may be.
 
GT  Global believes that this information may be useful to investors considering
whether and to what extent to  diversify their 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 any of the  Funds, nor is it a
prediction of such performance.  The performance of the  Funds will differ  from
the  historical performance of relevant indices. The performance of indices does
not take  expenses  into  account,  while  each  Fund  incurs  expenses  in  its
operations,  which will reduce performance. Each of these factors will cause the
performance of each Fund to differ from relevant indices.
 
   
From time  to  time,  each Fund  and  GT  Global  may refer  to  the  number  of
shareholders  in the  Funds or  the aggregate number  of shareholders  in all GT
Global Mutual Funds or the dollar amount of each Fund's assets under  management
or rankings by DALBAR Surveys, Inc. in advertising materials.
    
 
GT  Global believes the GT Global Income  Funds can be 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 GT  Global
Income  Funds do not  represent a complete investment  program and the investors
should consider  the  Funds  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  Funds.
Ibbotson calculates total returns in the same method as the Funds.
 
   
Each  Fund may quote  various measures of  volatility and benchmark correlation,
such as beta,  standard deviation and  R(2), in advertising.  In addition,  each
Fund  may compare these measures to those of other funds. Measures of volatility
seek to compare each Fund's historical share price fluctuations or total  return
to those of a benchmark.
    
 
Each  Fund may advertise  examples of the effects  of periodic investment plans,
including the principle of dollar cost averaging programs. In such a program, an
investor invests a fixed dollar amount in a Fund at periodic intervals,  thereby
purchasing  fewer shares when  prices are high  and more shares  when prices are
low. While such a strategy does not assure  a profit or guard against loss in  a
declining  market, the investor's  average cost per  share can be  lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating  such
a  plan, investors should  consider their ability  to continue purchasing shares
through periods of low price levels.
 
Each 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

plans  and  programs.  See "Information  Relating  to Sales  and  Redemptions --

GT Global may from time to time in its sales methods and advertising discuss the
risks inherent in investing. The major types of investment risk are market risk,
industry risk,  credit  risk,  interest  rate  risk  and  inflation  risk.  Risk
represents the possibility that you may lose some or all of your investment over
a  period  of time.  A basic  tenet of  investing is  the greater  the potential
reward, the greater the risk.

From time  to  time, GT  Global  may include  in  its advertisements  and  sales
material,   information  about  privatization,  which  is  an  economic  process
involving the sale of state-owned companies to the private sector.
    
 
In advertising and sales materials, GT  Global may make reference to or  discuss
its products, services and accomplishments. Among these accomplishments are that
in  1983  the Manager  provided assistance  to  the government  of Hong  Kong in
linking its currency to the  U.S. dollar, and that  in 1987 Japan's Ministry  of
Finance  licensed  LGT  Asset  Management  Ltd.  as  one  of  the  first foreign
discretionary investment managers for Japanese investors. Such  accomplishments,
however, should not be viewed as an endorsement of the Manager by the government
of  Hong Kong, Japan's Ministry of Finance or any other government or government
agency. Nor do  any such accomplishments  of the Manager  provide any  assurance
that the GT Global Mutual Funds' investment objectives will be achieved.

GT GLOBAL ADVANTAGE
As  part of Liechtenstein Global Trust,  GT Global continues a 75-year tradition
of  service  to  individuals  and  institutions.  Today  we  bring  investors  a
combination of experience, worldwide resources, a global perspective, investment
talent and a time-tested investment discipline. With investment professionals in
nine  offices  worldwide,  we  witness world  events  and  economic developments
firsthand. Many of the GT Global Mutual Funds' portfolio managers are natives of
the countries in which they invest, speak local languages and/or live or work in
the markets they follow.
 
The key to achieving  consistent results is  following a disciplined  investment
process.  Our  approach  to  asset allocation  takes  advantage  of  GT Global's
worldwide  presence  and  global  perspective.  Our  "macroeconomic"   worldview
determines our overall strategy of regional, country and sector allocations. Our
bottom-up  process  of  security selection  combines  fundamental  research with
quantitative analysis through our proprietary models.
 
   
Built-in checks  and balances  strengthen  the process,  enhancing  professional
experience  and judgment with an objective  assessment of risk. Ultimately, each
security we select has  passed a ranking system  that helps our portfolio  teams
determine  when to buy and when to sell.  With respect to stocks, a global stock
research ("GSR") database developed  by GT Global is  utilized in the  selection
process.  All stocks  within the GSR  database are systematically  ranked by our
analysts on a  1-5 basis  with 1 representing  the most  favored. The  rankings,
along  with our quantitative,  fundamental research, determine  which stocks are
bought and sold.
    
 
In addition, the GT Global Strategic Income  Fund and the GT Global High  Income
Fund,  from time to time,  may quote yields and  total returns of representative
debt instruments from  emerging market  countries in its  advertising and  sales
literature.
 
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.
 
ECONOMIC DEVELOPMENT IN EMERGING MARKETS
The Manager  has identified  six  phases to  track  the progress  of  developing
economies.
 
In addition, the Manager focuses on the transitions between each phase:
 
    BETWEEN  PHASES 1 & 2, STABILIZATION:  Developing nations recognize the need
for economic reform and launch initiatives to stabilize their economies. Typical
measures  might  include  initiating  monetary  reforms  to  contain  inflation,
controlling government spending, and addressing external trade imbalances.
 
    BETWEEN  PHASES 2 & 3, RENOVATION:  Economic development gathers momentum as
the  governments  of   developing  nations  take   further  steps  to   increase
productivity and external competitiveness. Typical reforms include easing market
regulations,  privatizing  state-owned industries,  lowering trade  barriers and
reforming the national tax structure.
 
    BETWEEN PHASES  3 &  4, NEW  CONSTRUCTION: As  economic reforms  take  hold,
infrastructure  improvements  are  needed to  facilitate  and  support long-term
growth. The construction and upgrading of highways and airports,  communications
and  utility systems  generally require  financing in  the form  of public debt.
Similarly, as  the private  sector develops,  bolstered by  new  privatizations,
corporate debt securities typically are issued to finance business expansion.

EMERGING MARKET TRADING VOLUME
The annual trading volume of debt securities from developing economies according
to  Salomon Brothers, Inc. has grown from $90 billion in 1990 to $150 billion in
1991, to $400 billion in 1992 and was estimated to be $1,200 billion at the  end
of 1993 and $1.5 trillion at the end of 1994, respectively.

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

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

<PAGE>
                             GT GLOBAL INCOME FUNDS
fixed  financial charges and high internal cash generation; and well-established
access to  a  range  of  financial markets  and  assured  sources  of  alternate
liquidity.  Issues rated Prime-2  have a strong ability  for repayment of senior
short-term debt obligations.  This normally  will be  evidenced by  many of  the
characteristics cited above but to a lesser degree. Earnings trends and coverage
ratios,   while  sound,  may  be   more  subject  to  variation.  Capitalization
characteristics, while  still  appropriate, may  be  more affected  by  external
conditions. Ample alternate liquidity is maintained.
 
    S&P  ratings of commercial paper are  graded into several categories ranging
from "A1" for the highest quality obligations  to "D" for the lowest. Issues  in
the  "A"  category are  delineated  with numbers  1, 2,  and  3 to  indicate the
relative degree  of safety.  A-1 --  This highest  category indicates  that  the
degree  of safety regarding timely payment is strong. Those issues determined to
possess extremely strong safety characteristics will be denoted with a plus sign
(+) designation.  A-2  -- Capacity  for  timely  payments on  issues  with  this
designation  is satisfactory; however,  the relative degree of  safety is not as
high as for issues designated "A-1."

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

1. SIGNIFICANT ACCOUNTING POLICIES
GT Global Government Income Fund, GT Global High Income Fund, GT Global
Strategic Income Fund ("Funds") are non-diversified separate series of G.T.
Investment Funds, Inc. ("Company"). Collectively, these Funds are known as the
"GT Global Income Funds". 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.
 
The GT Global High Income Fund invests substantially all of its investable
assets in Global High Income Portfolio ("Portfolio"). The Portfolio is organized
as a New York Trust and is registered under the 1940 Act as a non-diversified,
open-end management investment company.
 
The Portfolio has investment objectives, policies and limitations substantially
identical to those of its corresponding Fund. Therefore, the financial
statements of the Fund and its respective Portfolio have been presented on a
consolidated basis, and represent all activities of both the Fund and Portfolio.
Through October 31, 1997, all of the shares of beneficial interest of the
Portfolio were owned by either its Fund or Chancellor LGT Asset Management, Inc.
(the "Manager"), which has a nominal ($100) investment in the Portfolio.
 
The Funds 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 Funds 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
Funds. Each class of shares differs in its respective service and distribution
expenses, and may differ in its transfer agent, registration, and certain other
class-specific fees and expenses.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies in conformity with generally accepted accounting
principles consistently followed by the Funds in the preparation of the
financial statements.
 
(A) PORTFOLIO VALUATION
 
The Funds calculate the net asset value of and complete 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 the Manager to be the
primary market.
 
Fixed income investments are valued at the mean of representative quoted bid and
ask prices for such investments or, if such prices are not available, at prices
for investments of comparative maturity, quality, and type; however, when the
Manager deems it appropriate, prices obtained for the day of valuation from a
bond pricing service will be used. Short-term investments are valued at
amortized cost adjusted for foreign exchange translation and market 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
Company's Board of Directors or the Trust's Board of Trustees.
 
Portfolio securities which are primarily traded on foreign exchanges are
generally valued at the preceding closing values of such securities on their
respective exchanges, and those values are then translated into U.S. dollars at
the current exchange rates, except that when an occurrence subsequent to the
time a value was so established is likely to have materially changed such value,
then the fair value of those securities will be determined by consideration of
other factors by or under the direction of the Company's Board of Directors or
the Trust's Board of Trustees.
 
(B) FOREIGN CURRENCY TRANSLATION
The accounting records of each Fund and Portfolio are maintained in U.S.
dollars. The market values of foreign securities, currency holdings, and other
assets and liabilities are recorded in the books and records of the Funds or
Portfolio (the phrase "Funds or Portfolio" hereinafter refers to the GT Global
Government Income Fund, the GT Global Strategic Income Fund, and the Global High
Income Portfolio) 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.
 
A Fund or Portfolio does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss from
investments.
 
                                      F28
<PAGE>
                             GT GLOBAL INCOME FUNDS
 
Reported net realized foreign exchange gains or losses arise from sales and
maturities of short-term securities, forward foreign currency contracts, sales
of foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on a
Fund's or Portfolio's books and the U.S. dollar equivalent of the amounts
actually received or paid. Net unrealized foreign exchange gains or losses arise
from changes in the value of assets and liabilities other than investments in
securities at period end, resulting from changes in exchange rates.
 
(C) REPURCHASE AGREEMENTS
With respect to repurchase agreements entered into by a Fund or Portfolio, it is
the Fund's or Portfolio'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 or Portfolio 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 a Fund or Portfolio as an unrealized gain or loss.
When the Forward Contract is closed, the Fund or Portfolio records a realized
gain or loss equal to the difference between the value at the time it was opened
and the value at the time it was closed. Forward Contracts involve market risk
in excess of the amount shown in the Fund's or Portfolio's "Statement of Assets
and Liabilities". A Fund or Portfolio could be exposed to risk if a counterparty
is unable to meet the terms of the contract or if the value of the currency
changes unfavorably. A Fund or Portfolio 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 a Fund or Portfolio writes a call or put option, an amount equal to the
premium received is included in the Fund's or Portfolio'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 or Portfolio 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 or Portfolio can write options only on a covered basis,
which, for a call, requires that the Fund or Portfolio hold the underlying
security and, for a put, requires the Fund or Portfolio 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 or Portfolio may use options to manage its
exposure to the stock market and to fluctuations in currency values or interest
rates.
 
The premium paid by the Fund or Portfolio for the purchase of a call or put
option is included in the Fund's or Portfolio'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 or Portfolio has
purchased expires on the stipulated expiration date, the Fund or Portfolio
realizes a loss in the amount of the cost of the option. If the Fund or
Portfolio enters into a closing sale transaction, the Fund or Portfolio 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 or Portfolio
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 or Portfolio
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 or Portfolio 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 or Portfolio 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 or Portfolio 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 a
Fund or Portfolio 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 or Portfolio
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 or Portfolio as unrealized gains
or losses. When the contract is closed, the Fund or Portfolio 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 or Portfolio is that the change in value of the underlying
securities may not correlate to the change in value of the contracts. A Fund or
 
                                      F29
<PAGE>
                             GT GLOBAL INCOME FUNDS
 
Portfolio may use futures contracts to manage its exposure to the stock market
and to fluctuations in currency values or interest rates.
 
(G) SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME
Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). The cost of securities sold is determined on a first-in,
first-out-basis, unless otherwise specified. Dividends are recorded on the
ex-dividend date. Interest income is recorded on the accrual basis. Where a high
level of uncertainty exists as to its collection, income is recorded net of all
withholding tax with any rebate recorded when received. A Fund or Portfolio may
trade securities on other than normal settlement terms. This may increase the
risk if the other party to the transaction fails to deliver and causes the Fund
or Portfolio to subsequently invest at less advantageous prices.
 
(H) PORTFOLIO SECURITIES LOANED
At October 31, 1997, stocks with an aggregate value listed below were on loan to
brokers. The loans were secured by cash collateral received by the Funds:

</TABLE>
 
For international securities, cash collateral is received by a Fund or Portfolio
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 a Fund or Portfolio against loaned securities in the
amount at least equal to 102% of the market value of the loaned securities at
the inception of each loan. This collateral must be maintained at not less than
100% of the market value of the loaned securities during the period of the loan.
Fees received from securities loaned were used to reduce the Funds' or
Portfolios' custodian and other administrative expenses.
 
(I) TAXES
It is the intended policy of the Funds and Portfolios 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 Funds and
Portfolios to make distributions sufficient to avoid imposition of any excise
tax under Section 4982 of the Code. Therefore, no provision has been made for
Federal taxes on income, capital gains, or unrealized appreciation of securities
held, and excise tax on income and capital gains. The GT Global Government
Income Fund has a capital loss carryforward of $139,369,056 of which
$123,623,470 expires in 2002, and $15,745,586 expires in 2003. The GT Global
Strategic Income Fund has a capital loss carryforward of $65,749,433 which
expires in 2003.
 
(J) DISTRIBUTIONS TO SHAREHOLDERS
Distributions to shareholders are recorded by each 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 Funds or Portfolio and timing
differences.
 
(K) DEFERRED ORGANIZATIONAL EXPENSES
Expenses incurred by the GT Global High Income Fund and the Portfolio in
connection with their organization, their initial registration with the
Securities and Exchange Commission and with various states and the initial
public offering of its shares aggregated $149,100 and $25,000, respectively.
These expenses were 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 or Portfolio's investment in emerging
market countries may involve greater risks than investments in more developed
markets and the price of such investments may be volatile. These risks of
investing in foreign and emerging markets may include foreign currency exchange
rate fluctuations, perceived credit risk, adverse political and economic
developments and possible adverse foreign government intervention.
 
(M) INDEXED SECURITIES
A Fund or Portfolio 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
A Fund or Portfolio 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
or Portfolio's Portfolio of Investments.

                             GT GLOBAL INCOME FUNDS
 
(O) LINE OF CREDIT
Each of the Funds, along with certain other funds ("GT Funds") advised or
administered by the Manager, has a line of credit with BankBoston. GT Global
Income Funds, along with certain other funds ("GT Funds") advised or
administered by the Manager, has a line of credit with State Street Bank & Trust
Company. The arrangements with the banks allow all specified funds and the GT
Funds to borrow an aggregate maximum amount of $200,000,000. Each Fund is
limited to borrowing up to 33 1/3% of the value of each Fund's total assets. On
October 31, 1997, GT Global Government Income Fund had $4,451,000 in loans
outstanding.
 
For the year ended October 31, 1997, the weighted average outstanding daily
balance of bank loans (based on the number of days the loans were outstanding)
for GT Global Government Income Fund, GT Global High Income Fund, and GT Global
Strategic Income Fund was $7,107,892, $11,820,513 and $10,277,220 respectively,
with a weighted average interest rate of 6.33%, 6.47% and 6.38%, respectively.
Interest expense for the GT Global Government Income Fund, GT Global High Income
Fund and GT Global Strategic Income Fund for the year ended October 31, 1997 was
$103,696, $165,711 and $230,880, respectively, included in "Other Expenses" on
the Statement of Operations.
 
(P) SECURITIES PURCHASED ON A WHEN-ISSUED OR FORWARD COMMITMENT BASIS
A Fund or Portfolio 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 or Portfolio 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 or Portfolio has set aside sufficient cash or liquid
securities as collateral for these purchase commitments.
 
2. RELATED PARTIES
Chancellor LGT Asset Management, Inc. is the Funds' and Portfolio's investment
manager and administrator. The GT Global Government Income Fund and GT Global
Strategic Income Fund each pays the Manager investment management and
administration fees at the annualized rate of 0.725% on the first $500 million
of the average daily net assets of the Fund; 0.70% on the next $1 billion;
0.675% on the next $1 billion; and 0.65% on amounts thereafter. The GT Global
High Income Fund pays administration fees to the Manager at the annualized rate
of 0.25% of its average daily net assets. These fees are computed daily and paid
monthly.
 
The Global High Income Portfolio pays investment management and administration
fees to the Manager at the annualized rate of 0.475% on the first $500 million
of average daily net assets of the Portfolio; 0.45% on the next $1 billion;
0.425% on the next $1 billion; and 0.40% on amounts thereafter, plus 2% of the
Portfolio's total investment income calculated in accordance with generally
accepted accounting principles, adjusted daily for currency revaluations, on a
mark to market basis, of the Portfolio's assets; provided, however, that during
any fiscal year this amount shall not exceed 2% of the Portfolio's total
investment income calculated in accordance with generally accepted accounting
principles. These fees are computed daily and paid monthly.
 
GT Global, Inc. ("GT Global"), an affiliate of the Manager, serves as the Funds'
distributor. The Funds offer 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 Funds' current
prospectus. GT Global collects the sales charges imposed on sales of Class A
shares, and reallows a portion of such charges to dealers through which the
sales are made. For the year ended October 31, 1997, GT Global retained the
following sales charges: $10,240 for the GT Global Government Income Fund,
$65,982 for the Global High Income Fund, and $29,451 for the GT Global Strategic
Income Fund. Purchases of Class A shares exceeding $500,000 may be subject to a
contingent deferred sales charge ("CDSC") upon redemption, in accordance with
the Funds' current prospectus. GT Global collected CDSCs for the year ended
October 31, 1997, as follows: $5,273 for the GT Global Government Income Fund,
$18,156 for the Global High Income Fund, and $0 for the GT Global Strategic
Income Fund. 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 Funds' current
prospectus. For the year ended October 31, 1997, GT Global collected CDSCs in
the amount of: $1,118,343 for the GT Global Government Income Fund, $1,598,989
for the Global High Income Fund, and $1,750,253 for the GT Global Strategic
Income Fund. 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 Funds' Class A shares
("Class A Plan") and Class B shares ("Class B Plan"), pursuant to which a Fund
reimburses GT Global for a portion of its shareholder servicing and
distributions expenses. Under the Class A Plan, a Fund may pay GT Global a
service fee at the annualized rate of up to 0.25% of the average daily net
assets of the Fund's Class A shares for GT Global's expenditures incurred in
servicing and maintaining shareholder accounts, and may pay GT Global a
distribution fee at the annualized rate of up to 0.35% of the average daily net
assets of the Fund's Class A shares, less any amounts paid by the Fund as the
aforementioned service fee, for GT Global's expenditures incurred in providing
services as distributor. All expenses for which GT Global is reimbursed under
the Class A Plan will have been incurred within one year of such reimbursement.

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 each GT Global
Government Income Fund's and GT Global Strategic Income Fund's expenses
(exclusive of brokerage commissions, taxes, interest, and extraordinary expense)
to the maximum annual rate of 1.85%, 2.50%, and 1.50% of the average daily net
assets of the Fund's Class A, Class B, and Advisor Class shares, respectively.
Similarly, they voluntarily have undertaken to limit GT Global High Income
Fund's expenses to the maximum annual rate of 2.20%, 2.85%, and 1.85% of the
average daily net assets of the Fund's Class A, Class B, and Advisor Class
shares, respectively. If necessary, this limitation will be effected by waivers
by the Manager of investment management and administration fees, waivers by GT
Global of payments under the Class A Plan and/or Class B Plan and/or
reimbursements by the Manager or GT Global of portions of the Fund's other
operating expenses.
 
Effective November 1, 1997, the Manager and GT Global have undertaken to limit
each Fund's expenses (exclusive of brokerage commissions, taxes, interest, and
extraordinary expenses) to the annual rate of 1.75%, 2.40%, and 1.40% of the
average daily net assets of the Fund's Class A, Class B and Advisor Class
shares, respectively. This undertaking may be changed or eliminated in the
future.
 
GT Global Investor Services, Inc. ("GT Services"), an affiliate of the Manager
and LGT and GT Global, is the transfer agent of the Funds. 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 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 Funds and Portfolio. The
monthly fee for these services to the Manager is a percentage, not to exceed
0.03% annually, of a Fund or Portfolio'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 each 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 other affiliated company, $5,000 per year plus
$300 for each meeting of the board or any committee thereof attended by the
Director. Each Portfolio pays each of its Trustees who is not an employee,
officer, or director of the Manager, GT Global or GT Services $500 per year plus
$150 for each meeting of the board or any committee thereof attended by the
Trustees.
