- --------------------------------------------------------------------------------
 
GT GLOBAL NEW DIMENSION FUND (the "Fund") seeks long-term growth of capital.
Unlike a typical mutual fund, which invests directly in portfolio securities,
the Fund invests substantially all of its assets in shares of the GT Global
theme mutual funds: GT Global Consumer Products and Services Fund; GT Global
Financial Services Fund; GT Global Health Care Fund; GT Global Infrastructure
Fund; GT Global Natural Resources Fund; and GT Global Telecommunications Fund
(collectively, the "Underlying Theme Funds").
 
There is no assurance that the Fund will achieve its investment objective.
 
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 Fund is managed by Chancellor LGT Asset Management, Inc. (the "Manager").
The Manager and its worldwide affiliates are part of Liechtenstein Global Trust,
a provider of global asset management and private banking products and services
to individual and institutional investors.
 
This Prospectus sets forth concisely the information an investor should know
before investing and should be read carefully and retained for future reference.
A Statement of Additional Information, dated January 1, 1998, has been filed
with the Securities and Exchange Commission ("SEC") and, as supplemented or
amended from time to time, is incorporated by reference. The Statement of
Additional Information is available without charge by writing to the Fund at 50

                               PROSPECTUS SUMMARY
- ------------------------------------------------------------
The following summary is qualified in its entirety by the more detailed
information appearing in the body of this Prospectus. Cross-references in the
summary are to headings in the body of this Prospectus.
 
<TABLE>
<S>                            <C>                               <C>
The Fund:                                         The Fund is a diversified series of GT Global Series Trust ("the Trust").
Investment Objective:          The Fund seeks long-term growth of capital.
Principal Investments:         The Fund invests, under normal circumstances, substantially all of
                               its assets in shares of the following Underlying Theme Funds: GT
                               Global Consumer Products and Services Fund ("Consumer Products and
                               Services Fund"); GT Global Financial Services Fund ("Financial
                               Services Fund"); GT Global Health Care Fund ("Health Care Fund");
                               GT Global Infrastructure Fund ("Infrastructure Fund"); GT Global
                               Natural Resources Fund ("Natural Resources Fund"); and GT Global
                               Telecommunications Fund ("Telecommunications Fund"). The
                               allocation of the Fund's assets to the Underlying Theme Funds is
                               governed strictly by a formula described herein. See "Investment
                               Objective and Policies."
                               There is no assurance that the Fund will achieve its investment
                               objective. The Fund's net asset value will fluctuate, reflecting
                               fluctuations in the net asset value of the shares of the
                               Underlying Theme Funds. Investors should review the investment
                               objectives and policies of the Fund and the Underlying Theme Funds
                               carefully and consider their ability to assume these and other
                               risks involved in purchasing shares of the Fund. See "Investment
                               Objective and Policies," "Description of the Underlying Theme
                               Funds" and "Risk Factors and Special Considerations." As a
                               recently organized entity, the Fund has a limited operating
                               history.
Investment Manager:            The Manager is part of Liechtenstein Global Trust, a provider of
                               global asset management and private banking products and services
                               to individual and institutional investors, entrusted with

                               maintain investment offices in Frankfurt, Hong Kong, London, New
                               York, San Francisco, Singapore, Sydney, Tokyo and Toronto. See

                               for different investors, and investors should choose the class
                               that best suits their circumstances and objectives. See "How to
                               Invest."

- ------------------
*   Sales charge waivers are available for Class A, Class B and Class C shares,
    and reduced sales charges 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 declines thereafter,
    reaching zero after six years. The 1% contingent deferred sales charge on
    Class C shares applies only to redemptions during the first year after
    purchase. See "How to Invest."
 
+   The Annual Fund Operating Expenses are estimated for the Fund's initial
    fiscal period. "Other expenses" (including transfer agency, legal and audit
    fees and other operating expenses) initially will be borne by the Manager.
    Subject to receipt of an order of the SEC pursuant to a pending exemptive
    application and a private letter ruling issued by the Internal Revenue
    Service, such expenses may be borne by the Manager and the Underlying Theme
    Funds or the Underlying Theme Funds alone. See "Other Information -- Special
    Servicing Agreement." 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. See "Management" and the Statement of Additional Information for
    more information. The Fund also offers Advisor Class shares, which are not
    subject to 12b-1 distribution and service fees, to certain categories of
    investors. See "How to Invest."
 
In addition to the Annual Fund Operating Expenses shown above, the Fund, as a
shareholder in the Underlying Theme Funds, indirectly bears its pro rata share
of the fees and expenses incurred by the Underlying Theme Funds. As a result,
the investment returns of the Fund reflect the expenses of the Underlying Theme
Funds in which it holds shares. Because the Fund invests only in Advisor Class
shares of the Underlying Theme Funds, it pays no sales charge or 12b-1
distribution or service fees in connection with these investments. The following
table shows the expense ratios applicable to Advisor Class shares of the
Underlying Theme Funds for their fiscal years ended October 31, 1997.

(1) Effective November 1, 1997, the Manager has undertaken to limit each
    Underlying Theme Fund's expenses (exclusive of brokerage commissions, taxes,

    average daily net assets of such fund's Advisor Class shares. This

The following table shows the aggregate expense ratio of each class of the Fund
based on a weighted average of the expense ratios of Advisor Class shares of the
Underlying Theme Funds in which the Fund was invested as of October 31, 1997,
plus the Fund's total operating expenses. (1)

                            INVESTMENT OBJECTIVE AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
 
The Fund seeks long-term growth of capital. Unlike a typical mutual fund, which
invests directly in securities, the Fund invests, under normal circumstances,
substantially all of its assets in the following Underlying Theme Funds:
 
    / / Consumer Products and Services Fund
 
    / / Financial Services Fund
 
    / / Health Care Fund
 
    / / Infrastructure Fund
 
    / / Natural Resources Fund
 
    / / Telecommunications Fund
 
The Manager exercises no discretion in investing the Fund's assets. Rather, the
Manager periodically determines the allocation of the Fund's assets to the
Underlying Theme Funds according to the industry weightings of the companies
composing the Morgan Stanley Capital International All Country (AC) World Index
("MSCI"). (The MSCI is a broad unmanaged index of global stock prices,
comprising approximately 2,480 different issuers, located in 47 countries
including both developed and developing countries as of November 30, 1997. Each
of the 2,480 stocks is placed into one of 38 MSCI industry sectors.) The Manager
assesses which of the Underlying Theme Funds can invest, as part of its primary
focus, in each of these industries. For example, industries in the MSCI in which
the Financial Services Fund invests include the Banking, Financial Services,
Insurance and Real Estate industries. The percentage that those industries
compose in the MSCI is the initial weighting assigned to the Financial Services
Fund. Where two or more Underlying Theme Funds can invest in an industry, the
weighting of that industry in the MSCI is split equally among each qualifying
Underlying Theme Fund. See the Appendix for the allocation of the 38 industries
to the Underlying Theme Funds. Of course, the Underlying Theme Funds do not
invest necessarily in the same industries or the same companies that compose the
MSCI. Because the percentage weight assigned to each industry in the MSCI
changes over time and because the percentage of the Fund's assets invested in
each Underlying Theme Fund will change over time, the Manager will rebalance the
Fund's assets among the Underlying Theme Funds at least semi-annually. In
addition, the Manager will invest incoming money in, and satisfy redemption
requests by redeeming shares of, each Underlying Theme Fund according to the
MSCI weighting as of the last business day of the preceding month.
 
As of October 31, 1997, the allocation of the Fund's assets to the Underlying
Theme Funds was as follows:
 
<TABLE>
<S>                                       <C>
Consumer Products and Services Fund.....     28.69%
Financial Services Fund.................     19.16%
Health Care Fund........................      8.80%
Infrastructure Fund.....................     11.89%
Natural Resources Fund..................     15.85%
Telecommunications Fund.................      8.02%
</TABLE>
 
These percentages do not include cash or money market instruments held by the
Fund and do not necessarily reflect the current allocation of the Fund's assets
to the Underlying Theme Funds or the allocation of the Fund's assets on any
other date.
 
The Fund is a more diversified investment than any single Underlying Theme Fund.
However, because the Underlying Theme Funds are actively managed without any
attempt to reflect the country, industry or company weightings of the MSCI, the
Underlying Theme Funds will perform differently than the corresponding industry
components of the MSCI, and the Underlying Theme Funds will perform differently
than the overall MSCI. While the Fund does not therefore represent the
performance of the MSCI, it does represent a globally diversified portfolio,
with allocations among developed and emerging countries, industries and
companies intended to achieve long-term growth of capital.
 
The Fund is designed to meet the needs of investors who seek professional money
management services and who appreciate the advantages of diversification. The
Fund by itself should not be considered a complete investment program. As a
recently organized entity, the Fund has a limited operating history.

                                RISK FACTORS AND
                             SPECIAL CONSIDERATIONS
 
- --------------------------------------------------------------------------------
 
INVESTING IN THE UNDERLYING THEME FUNDS. The investments of the Fund are
concentrated in the Underlying Theme Funds, so the Fund's investment performance
is directly related to the investment performance of the Underlying Theme Funds.
The ability of the Fund to meet its investment objective is directly related to
the allocation among those Underlying Theme Funds as well as the ability of the
Underlying Theme Funds to meet their objectives. There is no assurance that the
investment objective of the Fund or any Underlying Theme Fund will be achieved.
The value of the Underlying Theme Funds' domestic and foreign investments varies
in response to many factors. The value of equity securities held by an
Underlying Theme Fund will fluctuate in response to general market and economic
developments, as well as developments affecting the particular issuers of such
securities. In addition, the value of debt securities held by an Underlying
Theme Fund generally will fluctuate with changes in the perceived
creditworthiness of the issuers of such securities and interest rates.
 
Because each Underlying Theme Fund focuses its investments on particular
industries, an investment in each may be more volatile than that of other
investment companies that do not concentrate their investments in such a manner.
The value of the shares of each Underlying Theme Fund will be especially
susceptible to factors affecting the industries in which it focuses. In
particular, each of the industries is subject to governmental regulation that
may have a material effect on the products and services offered by companies in
these industries.
 
UNDERLYING THEME FUNDS' INVESTMENT ALLOCATION. The Manager allocates each
Underlying Theme Fund's (or its corresponding Portfolio's) assets among
securities of countries and in currency denominations where opportunities for
meeting each Underlying Theme Fund's investment objective are expected to be the
most attractive. Each Underlying Theme Fund may invest substantially in
securities denominated in foreign currencies. Under normal conditions, each
Underlying Theme Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 40% of the Financial Services Portfolio's and the Telecommunication Fund's
total assets, and no more than 50% of the Infrastructure Portfolio's, the
Natural Resources Portfolio's, the Health Care Fund's and the Consumer Products
and Services Portfolio's total assets.
 
In analyzing specific companies for possible investment the Manager, on behalf
of the Underlying Theme Funds, ordinarily looks for several of the following
characteristics: above-average per share earnings growth; high return on
invested capital; a healthy balance sheet; sound financial and accounting
policies and overall financial strength; strong competitive advantages;
effective research and product development and marketing; development of new
technologies; efficient service; pricing flexibility; strong management; and
general operating characteristics that will enable the companies to compete
successfully in their respective markets. In assessing companies for the Natural
Resources Portfolio, the Manager will also evaluate, among other factors, their
capabilities for expanded exploration and production, superior exploration
programs and production techniques and facilities, current inventories, expected
production and demand levels and the potential to accumulate new resources.
 
FOREIGN INVESTMENTS. The Underlying Theme Funds' investments in foreign
securities may involve risks in addition to those of U.S. investments, including
increased political and economic risk, as well as exposure to currency
fluctuations. By investing in foreign securities, the Underlying Theme Funds
also have increased economic and political risks as they are exposed to events
and factors in the various world markets. This is especially true of an
Underlying Theme Fund that invests in emerging markets. Many investments in
emerging markets are considered speculative and therefore may offer greater
return potential, but have significantly greater risk. Also, to the extent that
an Underlying Theme Fund's investments are denominated in foreign currencies,
changes in the value of foreign currencies can significantly affect the Fund's
share price.
 
                               Prospectus Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
LOWER QUALITY DEBT SECURITIES. The Fund may invest in an Underlying Theme Fund
that invests in high yield, high risk securities, commonly known as "junk
bonds." As a result, the Fund may be subject to some of the risks resulting from
high yield investing. The Fund also may invest in Underlying Theme Funds that
invest in medium grade bonds. Lower quality debt instruments generally offer a
higher current yield than that available from higher grade issues, but typically
involve greater risk. Lower rated and comparable unrated securities are
especially subject to adverse changes in general economic conditions, to changes
in the financial condition of their issuers, and to price fluctuation in
response to changes in interest rates. During periods of economic downturn or
rising interest rates, issuers of these instruments may experience financial
stress that could adversely affect their ability to make payments of principal
and interest and increase the possibility of default.
 
ILLIQUID SECURITIES. The Underlying Theme Funds may invest 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, securities that are subject to restrictions
on resale may not be available for sale or only at prices below the prices of
securities that are not subject to restrictions.
 
OPTIONS, FUTURES AND FORWARD CURRENCY TRANSACTIONS. Each Underlying Theme Fund
is authorized to enter into options, futures and forward currency transactions,
although they might not enter into such transactions. Options, futures and
forward 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 an Underlying Theme Fund invests;
(4) lack of assurance that a liquid secondary market will exist for any
particular option, futures contract or option thereon at any particular time;
(5) the possible loss of principal under certain conditions; and (6) the
possible inability of an Underlying Theme Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for an Underlying Theme Fund to sell a security at a
disadvantageous time, due to the need for the Underlying Theme Fund to maintain
"cover" or to set aside securities in connection with hedging transactions.
 
INVESTING IN SMALLER COMPANIES. Each Underlying Theme Fund may invest in smaller
companies that may present greater opportunities for capital appreciation, but
may also involve greater risks than large, established issuers. Such smaller
companies may have limited resources, and their securities may trade less
frequently and in more limited volume than the securities of larger, more
established companies. As a result, the prices of the securities of such smaller
companies may fluctuate to a greater degree than the prices of the securities of
other issuers.
 
OTHER INVESTMENT PRACTICES OF THE UNDERLYING THEME FUNDS. In addition to the
investment practices described in this Prospectus, the Underlying Theme Funds
may engage in certain other investment practices, including lending their
portfolio securities; purchasing securities on a when-issued or delayed delivery
basis; entering into repurchase or reverse repurchase agreements; and borrowing
money. Further information on the investment policies, practices and risks of
the Underlying Theme Funds can be found in the Statement of Additional
Information as well as the Underlying Theme Funds' prospectus and statement of
additional information.
 
PURCHASES AND REDEMPTIONS. From time to time, the Underlying Theme Funds may
experience relatively large purchases or redemptions due to rebalancing of the
Fund by the Manager. This may have a material effect on the Underlying Theme
Funds, because Underlying Theme Funds that experience redemptions as a result of
the rebalancing may have to sell portfolio securities and because Underlying
Theme Funds that receive additional cash will have to invest it. While it is
impossible to predict the overall impact of these transactions over time, there
could be adverse effects on portfolio management to the extent that Underlying
Theme Funds may be required to sell securities at times when they would not
otherwise do so, or receive cash that cannot be invested in an
 
                               Prospectus Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
expeditious manner. There may be tax consequences associated with purchases and
sales of securities, and such sales also may increase transaction costs.
 
MASTER-FEEDER STRUCTURE OF CERTAIN UNDERLYING THEME FUNDS. The Financial
Services Fund, Infrastructure Fund, Natural Resources Fund and Consumer Products
and Services Fund, unlike mutual funds that directly acquire and manage their
own portfolios of securities, each seeks its investment objective by investing
all of its investable assets in the Financial Services Portfolio, Infrastructure
Portfolio, Natural Resources Portfolio and Consumer Products and Services
Portfolio (each a "Portfolio"), respectively. Each Portfolio is a separate
investment company. Because each such Underlying Theme Fund will invest only in
its corresponding Portfolio, that Underlying Theme Fund's shareholders will
acquire only an indirect interest in the investments of that Portfolio.
 
TEMPORARY DEFENSIVE STRATEGIES. The Underlying Theme Funds retain the
flexibility to respond promptly to changes in market and economic conditions.
Accordingly, in the interest of preserving shareholders' capital the Manager may
employ a temporary defensive investment strategy if it determines such a
strategy to be warranted due to market, economic or political conditions. Under
a defensive strategy, the Underlying Theme Funds may invest up to 100% of their
total assets in cash and/or high quality debt securities and money market
instruments. To the extent an Underlying Theme Fund adopts a temporary defensive
posture, it will not be invested so as to achieve directly its investment
objective.
 
In addition, pending investment of proceeds from new sales of the shares or to
meet its ordinary daily cash needs, the Underlying Theme Funds may hold cash
and/or may invest in high quality debt instruments and money market instruments.
The Fund may hold cash and/or may invest in money market instruments under
similar circumstances. Money market instruments in which the Underlying Theme
Funds and the Fund may invest include, but are not limited to, United States
government securities; high-grade commercial paper; bank certificates of
deposit; bankers' acceptances and repurchase agreements related to any of the
foregoing. "High-grade commercial paper" refers to commercial paper rated A-1 by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc., or P-1 by
Moody's Investors Service, Inc. or, if not rated, determined by the Manager to
be of comparable quality.
 
PORTFOLIO TURNOVER. The Fund's portfolio turnover rate is expected to be low and
is not anticipated to exceed 20% annually. The portfolio turnover rates of the
Underlying Theme Funds and their corresponding Portfolios have ranged from 35%
to 392% during their most recent fiscal years. There is no assurance that the
turnover rates of the Underlying Theme Funds and their corresponding Portfolios
will remain within this range during subsequent fiscal years. Higher turnover
rates may result in higher expenses being incurred by the Underlying Theme
Funds.
 
AFFILIATED PERSONS. The officers and trustees of the Trust currently serve as
officers and trustees of the Underlying Theme Funds. The Manager also serves as
investment adviser and/or administrator to the Underlying Theme Funds.
Therefore, conflicts may arise as these persons fulfill their fiduciary
responsibilities to the Fund and the Underlying Theme Funds.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
GENERAL. Shares of the Fund may be purchased through broker/dealers and other
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 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. A
"Business Day" is any day Monday through Friday on which the NYSE is open for
business. Orders received by authorized institutions (or their designees) before
the close of regular trading on the NYSE on a Business Day will be deemed to
have been received by the Fund on such day and will be effected that day,
provided that such orders are transmitted to the Transfer Agent prior to the
time set for the receipt of such orders. The authorized institution (or its
designee) will be responsible for forwarding the investor's order to the
Transfer Agent so that it will be received prior to such time.
 
The minimum initial investment is $500 ($100 for IRAs and $25 for custodial
accounts under Section 403(b)(7) of the Internal Revenue Code of 1986, as
amended (the "Code"), and other tax-qualified employer-sponsored retirement
accounts, if made under a systematic investment plan providing for monthly
payments of at least that amount). The minimum for additional purchases is $100
($25 for IRAs, Code Section 403 (b)(7) custodial accounts and other
tax-qualified employer-sponsored retirement accounts, as mentioned above). THE
FUND AND GT GLOBAL RESERVE THE RIGHT TO REJECT ANY PURCHASE ORDER AND TO SUSPEND
THE OFFERING OF SHARES FOR A PERIOD OF TIME. In particular, the Fund and GT
Global may reject purchase orders or exchanges by investors who appear to
follow, in the Manager's judgment, a market-timing strategy or otherwise engage
in excessive trading. See "How To Make Exchanges -- Limitations on Purchase
Orders and Exchanges."
 
WHEN PLACING PURCHASE ORDERS, INVESTORS SHOULD SPECIFY WHETHER THE ORDER IS FOR
CLASS A, CLASS B OR CLASS C SHARES OF THE FUND. ALL PURCHASE ORDERS THAT FAIL TO
SPECIFY A CLASS WILL AUTOMATICALLY BE INVESTED IN CLASS A SHARES. PURCHASES OF
$500,000 OR MORE MUST BE FOR CLASS A SHARES.
 
PURCHASES THROUGH GT GLOBAL. After an initial investment is made and a
shareholder account is established through a broker/dealer or other financial
institution, at the investor's option subsequent purchases may be made directly
through GT Global. See "Shareholder Account Manual." Investors may also make an
initial investment in the Fund and establish a shareholder account directly
through GT Global by completing and signing an Account Application accompanying
this Prospectus. Investors should mail to the Transfer Agent the completed
Application together with a check to cover the purchase in accordance with the
instructions provided in the Shareholder Account Manual. Purchases will be
executed at the public offering price next determined after the Transfer Agent
has received the Account Application and check. Subsequent investments do not
need to be accompanied by an application.
 
Investors also may purchase shares of the Fund through GT Global by bank wire.
Bank wire purchases will be effected at the next determined public offering
price after the bank wire is received. A wire investment is considered received
when the Transfer Agent is notified that the bank wire has been credited to the
Fund. The investor is responsible for providing prior telephonic or facsimile
notice to the Transfer Agent that a bank wire is being sent. An investor's bank
may charge a service fee for wiring money to the Fund. The Transfer Agent
currently does not charge a service fee for facilitating wire purchases, but
reserves the right to do so in the future. Investors desiring to open an account
by bank wire should call the Transfer Agent at the appropriate toll-free number
provided in the Shareholder Account Manual to obtain an account number and
detailed instructions.

                          GT GLOBAL NEW DIMENSION FUND
 
CERTIFICATES. Physical certificates representing the Fund's shares will not be
issued unless a written request is submitted to the Transfer Agent. Shares of
the Fund are recorded on a register by the Transfer Agent, and shareholders who
do not elect to receive certificates have the same rights of ownership as if
certificates had been issued to them. Redemptions and exchanges by shareholders
who hold certificates may take longer to effect than similar transactions
involving non-certificated shares because the physical delivery and processing
of properly executed certificates is required. ACCORDINGLY, THE FUND AND GT
GLOBAL RECOMMEND THAT SHAREHOLDERS DO NOT REQUEST ISSUANCE OF CERTIFICATES.
 
DIFFERENCES AMONG THE CLASSES. The primary difference among the three classes of
the Fund's shares offered through this Prospectus lies in their sales charge
structures and ongoing expenses, as summarized below. Class A, Class B and Class
C shares represent the same interests in the 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 and Class C shares
have 100% of the purchase invested immediately. Investors intending to invest
for a relatively short period might consider Class C shares. Consult your
financial adviser. Broker/ dealers 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; and (e) any of those
companies.

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

(i) and (vii) described below under "Sales Charge Waivers -- Class A Shares."
 
The following purchases may be aggregated for purposes of determining the
"Amount of Purchase":
 
(a) Individual purchases on behalf of a single purchaser, the purchaser's spouse
and their children under the age of 21 years, including purchases in connection
with an employee benefit plan or plans exclusively for the benefit of such indi-
vidual(s), such as an IRA, individual Code Section 403(b)(7) plan or
single-participant self-employed individual retirement plan ("Keogh Plan") and
purchases made by a company controlled by such individual(s);
 
(b) Individual purchases by a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account, including an employee benefit
plan (such as employer-sponsored pension, profit-sharing and stock bonus plans,
including Code Section 401(k) plans, and medical, life and disability insurance
trusts) other than a plan described in "(a)" above; and
 
(c) Individual purchases by a trustee or other fiduciary purchasing shares
concurrently for two or more employee benefit plans of a single employer or of
employers affiliated with each other (again excluding an employee benefit plan
described in "(a)" above).
 
SALES CHARGE WAIVERS -- CLASS A SHARES. Class A shares are sold at net asset
value without imposition of sales charges when investments are made by the
following classes of investors:
 
(i) Trustees or other fiduciaries purchasing shares for employee benefit plans
which are sponsored by organizations which have at least 100 but less than 1,000
employees, and trustees or other fiduciaries purchasing shares for employee
benefit plans which are sponsored by organizations with collective retirement
plan assets of $500,000 or more and have less than 100 employees, and purchases
of at least $500,000 by trustees or other fiduciaries of employee benefit plans
with collective retirement plan assets of $100 million or more.
 
(ii) Current or retired Trustees, Directors and officers of the investment

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

the proceeds of which are reinvested in the Fund's shares.
 
(xi) Accounts for which a financial institution or broker/dealer charges an

Global Health Care Fund in October 1989, and who have continuously held shares
in the GT Global Mutual Funds since that time.
 
REINSTATEMENT PRIVILEGE. Shareholders who redeem their Class A shares in the
Fund have a one time privilege of reinstating their investment by investing the
proceeds of the redemption at net asset value without a sales charge in Class A
shares of the Fund and/or one or more of the other GT Global Mutual Funds. The
Transfer Agent must receive from the investor or the investor's broker/dealer
within 180 days after the date of the redemption both a written request for
reinvestment and a check not exceeding the amount of the redemption proceeds.
The reinstatement purchase will be effected at the net asset value per share
next determined after such receipt. Gain on the redemption is taxable
notwithstanding exercise of the reinvestment privilege (although loss thereon
might not be deductible as a result of such exercise). See "Dividends, Other
Distributions and Federal Income Taxation."
 
REDUCED SALES CHARGE PLANS -- CLASS A SHARES. Class A shares may be purchased at
reduced sales charges either through the Right of Accumulation or under a Letter
of Intent. For more details on these plans, investors should contact their
broker/ dealers or the Transfer Agent.
 
RIGHT OF ACCUMULATION. Pursuant to the Right of Accumulation, investors are
permitted to purchase shares of the Fund at the sales charge applicable to the
total of (a) the dollar amount then being purchased plus (b) the dollar amount
of the investor's concurrent purchases of other GT Global Mutual Funds (other
than GT Global Dollar Fund) plus (c) the price of all shares of GT Global Mutual
Funds (other than shares of GT Global Dollar Fund not acquired by exchange)
already held by the investor. To receive the Right of Accumulation, at the time
of purchase investors must give their broker/dealer, the Transfer Agent or GT
Global sufficient information to permit confirmation of qualification. THE
FOREGOING RIGHT OF ACCUMULATION APPLIES ONLY TO CLASS A SHARES OF THE FUND AND
OTHER GT GLOBAL MUTUAL FUNDS (OTHER THAN GT GLOBAL DOLLAR FUND).
 
LETTER OF INTENT. In executing a Letter of Intent ("LOI"), an investor indicates
an aggregate investment amount he or she intends to invest in the Class A shares
of the Fund and the Class A shares of other GT Global Mutual Funds (other than
shares of GT Global Dollar Fund) in the following thirteen months. The LOI is
included as part of the Account Application located at the end of this
Prospectus. The sales charge applicable to that aggregate amount then becomes
the applicable sales charge on all purchases made concurrently with the
execution of the LOI and in the thirteen months following that execution. If an
investor executes an LOI within 90 days of a prior purchase of GT Global Mutual
Fund Class A shares (other than shares of GT Global Dollar Fund), the prior
purchase may be included under the LOI and an appropriate adjustment, if any,
with respect to the sales charges paid by the investor in connection with the
prior purchase will be made, based on the then-current net asset value(s) of the
pertinent Fund(s).
 
If at the end of the thirteen month period covered by the LOI the total amount
of purchases does not equal the amount indicated, the investor will be required
to pay the difference between the sales charges paid at the reduced rate and the
sales charges applicable to the purchases actually made. Shares having a value
equal to 5% of the amount specified in the LOI will be held in escrow during the
thirteen month period (while remaining registered in the investor's name) and
are subject to redemption to assure any necessary payment to GT Global of a
higher applicable sales charge.
 
For purposes of an LOI, any registered investment adviser, trust company or bank
trust department which exercises investment discretion and which intends within
thirteen months to invest $500,000 or more can be treated as a single purchaser,
provided further that such entity places all purchase and redemption orders.
Such entities should be prepared to establish their qualifications for such
treatment. THE FOREGOING LOI APPLIES ONLY TO CLASS A SHARES OF THE FUND AND
OTHER GT GLOBAL MUTUAL FUNDS (OTHER THAN GT GLOBAL DOLLAR FUND).
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS A SHARES. Purchases of Class A shares
of $500,000 or more may be made without an initial 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
 
                               Prospectus Page 16
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
shares purchased without a sales charge may be exchanged for Class A shares of
another GT Global Mutual Fund (other than GT Global Dollar Fund) without the
imposition of a contingent deferred sales charge, although the contingent
deferred sales charge described above will apply to the redemption of the shares
acquired through an exchange. The waivers set forth under "Contingent Deferred
Sales Charge Waivers" below apply to redemptions of Class A shares upon which a
contingent deferred sales charge would otherwise be imposed. For federal income
tax purposes, the amount of the contingent deferred sales charge will reduce the
gain or increase the loss, as the case may be, realized on a redemption. The
amount of any contingent deferred sales charge will be paid to GT Global.
 
                           PURCHASING CLASS B SHARES
 
The public offering price of the Class B shares is the next determined net asset
value per share. See "Calculation of Net Asset Value." No initial sales charge
is imposed. A contingent deferred sales charge, however, is imposed on certain
redemptions of Class B shares. Because the Class B shares are sold without an
initial sales charge, the Fund receives the full amount of the investor's
purchase payment. Class B shares may not be purchased for a Savings Incentive
Match Plan for Employees IRA ("SIMPLE IRA") for which a designated financial
institution was selected by the employer on Form 5305-SIMPLE. However, Class B
shares may be purchased for SIMPLE IRAs using Form 5304-SIMPLE. In addition,
Class A shares may be purchased for all SIMPLE IRAs.
 
Class B shares will not be subject to a contingent deferred sales charge to the
extent that the value of such shares represents: (1) reinvestment of dividends
or capital gain 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.

Thereafter....................             0%
</TABLE>
 
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 $165.00 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 $10.00 per share would be used. The contingent deferred sales
charge calculation would therefore be 30.455 shares times $10.00 per share at
the 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
 
                               Prospectus Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
                          CONVERSION OF CLASS B SHARES
 
Class B shares automatically will convert to Class A shares as of the close of
business on the last business day of the month in which the seventh anniversary
of the initial issuance of such Class B shares occurs. The conversion will be
affected at the relative net asset value per share of each class. At the time of
conversion, a portion of Class B shares purchased through reinvestment of
dividends or other distributions ("Dividend Shares") also will convert to Class
A shares. The portion of Dividend Shares that will convert is determined by the
ratio of converting Class B non-Dividend Shares to the total Class B
non-Dividend Shares held by the shareholder.
 
                           PURCHASING CLASS C SHARES
 
The public offering price of the Class C shares of the Fund 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 of 1% of the
net asset value at the time of purchase or sale, whichever is less, however, is
charged on shares sold within one year of purchase. Because the Class C shares
are sold without an initial sales charge, the Fund receives the full amount of
the investor's purchase payment. Class C shares of the Fund may not be purchased
for a SIMPLE IRA for which a designated financial institution was selected by
the employer on Form 5305-SIMPLE. However, Class C shares of the Fund may be
purchased for SIMPLE IRAs using Form 5304-SIMPLE. In addition, Class A shares
may be purchased for all SIMPLE IRAs.
 
Class C 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. Redemptions of most other Class C shares will be subject to a
contingent deferred sales charge. See "Contingent Deferred Sales Charge
Waivers." 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 applicable to Class A, Class B or Class C
shares will be waived for (1) exchanges, as described below; (2) redemptions in
connection with the Fund's systematic withdrawal plan not in excess of 12% of
the value of the account annually; (3) total or partial redemptions made within
one year following the death or disability of a shareholder; (4) minimum
required distributions made in connection with a GT Global IRA, Keogh Plan or
custodial account under Section 403(b)(7) 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 or Class C shares of the Fund within 180 days of
a prior redemption; (8) redemptions pursuant to the Fund's right to liquidate a
shareholder's account involuntarily; (9) redemptions pursuant to a distribution
from a tax-qualified employer-sponsored retirement plan, which is invested in GT
Global Mutual Funds, that is permitted to be made without penalty pursuant to
the Code, other than tax-free rollovers or transfers of assets, and the proceeds
of which are reinvested in GT Global Mutual Funds; (10) redemptions made in
connection with participant-directed exchanges between options in an
employer-sponsored benefit plan; (11) redemptions made for the purpose of
providing cash to fund a loan to a participant in a tax-qualified retirement
plan; (12) redemptions made in connection with a distribution from any
retirement plan or account that is permitted in accordance with the provisions
of Section 72(t)(2) of the Code and the regulations promulgated thereunder; (13)

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, CLASS B AND CLASS C SHARES
 
AUTOMATIC INVESTMENT PLAN. Investors may purchase either Class A, Class B or
Class C shares of the Fund through the GT Global Automatic Investment Plan.
Under this Plan, an amount specified by the shareholder of $100 or more ($25 or
more for IRAs, Code Section 403(b)(7) custodial accounts and other tax-qualified
employer-sponsored retirement accounts) on a monthly or quarterly basis will be
sent to the Transfer Agent from the investor's bank for investment in the Fund.
Participants in the Automatic Investment Plan should not elect to receive
dividends or other distributions from the Fund in cash. A sales charge will be
applied to each automatic monthly purchase of Class A shares in an amount
determined in accordance with the Right of Accumulation privilege described
above. To participate in the Automatic Investment Plan, investors should
complete the appropriate portion of the Supplemental Application provided at the
end of this Prospectus. Investors should contact their brokers or GT Global for
more information.
 
DOLLAR COST AVERAGING PROGRAM. Investors may purchase either Class A, Class B or
Class C shares of the Fund through the GT Global Dollar Cost Averaging Program
whereby a shareholder invests the same dollar amount each month. Accordingly,
the investor purchases more shares when the Fund's net asset value is relatively
low and fewer shares when the Fund's net asset value is relatively high. This
can result in a lower average cost-per-share than if the shareholder followed a
less systematic approach. Dollar cost averaging does not assure a profit and
does not protect against loss in declining markets. Because such a program
involves continuous investment in securities regardless of fluctuating price
levels of such securities, investors should consider their financial ability to
continue purchases when prices are declining.
 
A participant in the GT Global Dollar Cost Averaging Program first designates
the size of his or her monthly investment in the Fund ("Monthly Investment")
after participation in the Program begins. The Monthly Investment must be at
least $1,000. The investor then will make an initial investment of at least
$10,000 in the GT Global Dollar Fund. Thereafter, each month an amount equal to
the specified Monthly Investment automatically will be redeemed from the GT
Global Dollar Fund and invested in Fund shares. A sales charge will be applied
to each automatic monthly purchase of Class A shares of the Fund in an amount
determined in accordance with the Right of Accumulation privilege described
above. Investors should contact their brokers or GT Global for more information.
 
PORTFOLIO REBALANCING PROGRAM. The GT Global Portfolio Rebalancing Program
permits eligible shareholders to establish and maintain an allocation across a
range of GT Global Mutual Funds. The Program is not available for Class C
shares. This Program automatically rebalances holdings of GT Global Mutual Funds
to the established allocation on a periodic basis. Under this 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 this 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 Funds in a shareholder's Personal Portfolio have
appreciated during a rebalancing period, the Program will result in shares of GT
Global Mutual Fund(s) that have appreciated most during the period being
exchanged for shares of GT Global Mutual Fund(s) that have appreciated least.
SUCH EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A
GAIN OR LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See
"Dividends, Other Distributions and Federal Income Taxation." Participation in
this 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
 
                               Prospectus Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 $7.50 service charge imposed on certain exchanges as
described below. 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 broker/dealers may charge a fee for
establishing accounts relating to the Program. Investors should contact their
broker/dealers or GT Global for more information.

                             HOW TO MAKE EXCHANGES
 
- --------------------------------------------------------------------------------
 
Class A and Class B shares of the Fund may be exchanged for shares of the
corresponding 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. Class C shares currently may not be exchanged
for shares of any other GT Global Mutual Fund. 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." The exchange of Class B shares will not be subject to a
contingent deferred sales charge. For purposes of computing the contingent
deferred sales charge, the length of time of ownership of Class B shares will be
measured from the date of original purchase and will not be affected by the
exchange. In addition to the Fund, the GT Global Mutual Funds currently include:
 
   -- GT GLOBAL AMERICA MID CAP GROWTH FUND
   -- GT GLOBAL AMERICA SMALL CAP GROWTH FUND
   -- GT GLOBAL AMERICA VALUE FUND
   -- GT GLOBAL CONSUMER PRODUCTS AND
       SERVICES FUND
   -- GT GLOBAL DEVELOPING MARKETS FUND
   -- GT GLOBAL DOLLAR FUND
   -- GT GLOBAL EMERGING MARKETS FUND
   -- GT GLOBAL EUROPE GROWTH FUND
   -- GT GLOBAL FINANCIAL SERVICES FUND
   -- GT GLOBAL GOVERNMENT INCOME FUND
   -- GT GLOBAL GROWTH & INCOME FUND
   -- GT GLOBAL HEALTH CARE FUND
   -- GT GLOBAL HIGH INCOME FUND
   -- GT GLOBAL INFRASTRUCTURE FUND
   -- GT GLOBAL INTERNATIONAL GROWTH FUND
   -- GT GLOBAL JAPAN GROWTH FUND
   -- GT GLOBAL LATIN AMERICA GROWTH FUND
   -- GT GLOBAL NATURAL RESOURCES FUND
   -- GT GLOBAL NEW PACIFIC GROWTH FUND
   -- GT GLOBAL STRATEGIC INCOME FUND
   -- GT GLOBAL TELECOMMUNICATIONS FUND
   -- GT GLOBAL WORLDWIDE GROWTH FUND
 
Up to four exchanges each year may be made without charge. A $7.50 service
charge will be imposed on each subsequent exchange. If an investor does not
surrender all of his or her shares in an exchange, the remaining balance in the
investor's account after the exchange must be at least $500. Exchange requests
received in good order by the Transfer Agent before the close of regular trading
on the NYSE on any Business Day will be processed at the net asset value
calculated on that day. The terms of the exchange offer may be modified at any
time, on 60 days' prior written notice.
 
An investor interested in making an exchange should contact his or her
broker/dealer or the Transfer Agent to request the prospectus of the other GT
Global Mutual Fund(s) being considered. Certain broker/dealers may charge a fee
for handling exchanges.
 
EXCHANGES BY TELEPHONE. A shareholder may give exchange instructions to the
shareholder's broker/ dealer or the Transfer Agent by telephone at the
appropriate toll-free number provided in the Shareholder Account Manual.
Exchange orders will be accepted by telephone provided that the exchange
involves only uncertificated shares on deposit in the shareholder's account or
for which certificates have previously been deposited. Shareholders
automatically have telephone privileges to authorize exchanges. The Fund, GT
Global and the Transfer Agent will not be liable for any loss or damage for
acting in good faith upon instructions received by telephone and reasonably
believed to be genuine. The Fund employs reasonable procedures to confirm that
instructions communicated by telephone are genuine prior to acting upon
instructions received by telephone, including requiring some form of personal
identification, providing written confirmation of such transactions, and/or tape
recording of telephone instructions.
 
EXCHANGES BY MAIL. Exchange orders should be sent by mail to the investor's
broker/dealer or to the Transfer Agent at the address set forth in the
Shareholder Account Manual.
 
LIMITATIONS ON PURCHASE ORDERS AND EXCHANGES. The GT Global Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market-timing
investment strategies and excessive trading can have on efficient portfolio
management, each GT Global Mutual Fund and GT Global reserve the right to refuse
purchase orders and exchanges by any person or group, if, in the Manager's
judgment, such person or group was following a market-timing strategy or was
otherwise engaging in excessive trading.
 
In addition, each GT Global Mutual Fund and GT Global reserve the right to
refuse purchase orders and exchanges by any person or group if, in the Manager's
judgment, the Fund would not be able to invest the money effectively in
accordance with that Fund's investment objective and policies or would otherwise
potentially be adversely affected. Although a GT Global Mutual Fund will attempt
to give investors prior notice whenever it is reasonably able to do so, it may
impose the above restrictions at any time.
 
Finally, as described above, each GT Global Mutual Fund and GT Global reserve
the right to reject any purchase order.

                              HOW TO REDEEM SHARES
 
- --------------------------------------------------------------------------------
 
Fund shares may be redeemed at their net asset value (subject to any applicable
contingent deferred sales charge for Class B or Class C 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 BROKER/DEALERS. Shareholders with accounts at broker/dealers
who sell shares of the Fund may submit redemption requests to such
broker/dealers. If the shares are held in the broker/dealer's "street name," the
redemption must be made through the broker/dealer. Broker/ dealers may honor a
redemption request either by repurchasing shares from a redeeming shareholder at
the Fund's shares' net asset value next determined after the broker/dealer
receives the request or, as described below, by forwarding such requests to the
Transfer Agent (see "How to Redeem Shares -- Redemptions Through the Transfer
Agent"). Redemption proceeds normally will be paid by check or, if offered by
the broker/ dealer, credited to the shareholder's brokerage account at the
election of the shareholder. Broker/ dealers may impose a service charge for
handling redemption transactions placed through them and may have other
requirements concerning redemptions. Accordingly, shareholders should contact
their broker/dealers 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 next determined after the Transfer Agent has
received the request in good order and any required supporting documentation
(less any applicable contingent deferred sales charge for Class B or Class C
shares or, in limited circumstances, Class A shares) or after an authorized
institution (or its designee) has received orders, provided such orders are
transmitted to the Transfer Agent prior to the time set for receipt of such
orders. 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 thirty days; or (ii) directly to a pre-designated bank, savings and
loan or credit union account ("Pre-Designated Account"). ALL OTHER REDEMPTION
REQUESTS MUST BE ACCOMPANIED BY A SIGNATURE GUARANTEE OF THE REDEEMING
SHAREHOLDER'S SIGNATURE. A signature guarantee can be obtained from any bank,
U.S. trust company, a member firm of a U.S. stock exchange or a foreign branch
of any of the foregoing or other eligible guarantor institution. A notary public
is not an acceptable guarantor. A shareholder with questions concerning the
Fund's signature guarantee requirement should contact the Transfer Agent.
 
Shareholders may qualify to have redemption proceeds sent to a Pre-Designated
Account by completing the appropriate section of the Account Application at the
end of this Prospectus. Shareholders with Pre-Designated Accounts should request
that redemption proceeds be sent either by bank wire or by check. The minimum
redemption amount for a bank wire is $1,000. Shareholders requesting a bank wire
should allow two business days from the time the redemption request is effected
for the proceeds to be deposited in the shareholder's Pre-Designated Account.
See "How to Redeem Shares -- Other Important Redemption Information."
Shareholders may change their Pre-Designated Accounts only by a letter of
instruction to the Transfer Agent containing all account signatures, each of
which must be guaranteed. The Transfer Agent currently does not charge a bank
wire service fee for each wire redemption sent, but reserves the right to do so
in the future. The shareholder's bank may charge a bank wire service fee.
 
REDEMPTIONS BY TELEPHONE. Redemption requests may be made by telephone by
calling the Transfer Agent at the appropriate toll-free number provided in the
Shareholder Account Manual. Shareholders who hold certificates for shares may
not redeem by telephone. REDEMPTION REQUESTS MAY NOT BE MADE BY TELEPHONE FOR
THIRTY DAYS

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
FOLLOWING ANY CHANGE OF THE SHAREHOLDER'S ADDRESS OF RECORD.
 
Shareholders automatically have telephone privileges to authorize redemptions.
The Fund, GT Global and the Transfer Agent will not be liable for any loss or
damage for acting in good faith upon instructions received by telephone and
reasonably believed to be genuine. The Fund employs reasonable procedures to
confirm that instructions communicated by telephone are genuine prior to acting
upon instructions received by telephone, including requiring some form of
personal identification, providing written confirmation of such transactions,
and/or tape recording of telephone instructions.
 
REDEMPTIONS BY MAIL. Redemption requests should be mailed directly to the
Transfer Agent at the appropriate address provided in the Shareholder Account
Manual. As discussed above, requests for payment of redemption proceeds to a
party other than the shareholder of record and/or requests that redemption
proceeds be mailed to an address other than the shareholder's address of record
require a signature guarantee. In addition, if the shareholder's address of
record has been changed within the preceding thirty 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, Class B or
Class C 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 broker/dealers 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 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 broker/dealers may have different
features. Accordingly, shareholders should contact their broker/ dealer for more
details.
 
OTHER IMPORTANT REDEMPTION INFORMATION. A request for redemption will not be
processed until all of the necessary documentation has been received in good
order. A shareholder in doubt as to what documents are required should contact
his or her broker/dealer or the Transfer Agent.
 
Except in extraordinary circumstances and as permitted under the 1940 Act,
payment for shares redeemed by telephone or by mail will be made promptly after
receipt of a redemption request, if in good order, but not later than seven days
after the date the request is executed. Requests for redemption which are
subject to any special conditions or which specify a future or past effective
date cannot be accepted.
 
If the Transfer Agent is requested to redeem shares for which the Fund has not
yet received good payment, the Fund may delay payment of redemption proceeds
until the Transfer Agent has assured itself that good payment has been collected
for the purchase of the shares. In the case of purchases by check it can take up
to 10 business days to confirm that the check has cleared and good payment has
been received. Redemption proceeds will not be delayed when shares have been
paid for by wire or when the investor's account holds a sufficient number of
shares for which funds already have been collected.
 
The Fund may redeem the shares of any shareholder whose account is reduced to
less than $500 in 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 NEW DIMENSION FUND
 
                         CALCULATION OF NET ASSET VALUE
 
- --------------------------------------------------------------------------------
 
The Fund calculates its net asset value as of the close of regular trading on
the NYSE (currently 4:00 p.m. Eastern Time, unless weather, equipment failure or
other factors contribute to an earlier closing time) each Business Day. The
Fund's net asset value per share is computed by dividing the value of the Fund's
net assets by the total number of Fund shares outstanding. Net asset value is
determined separately for each class of shares of the Fund. The assets of the
Fund consist primarily of shares of the Underlying Theme Funds, which are valued
daily at their respective net asset values at the time of computation. Other
Fund assets are valued at current market price or, if unavailable, at fair value
determined in good faith by or under the direction of the Trust's Board of
Trustees.
 
The different service and distribution fees borne by each class of shares of the
Fund will result in different net asset values. The per share net asset value of
the Class B and Class C shares generally will be lower than that of the Class A
shares because of the higher service and distribution fees borne by the Class B
and Class C shares. The per share net asset value of the Advisor Class shares
generally will be higher than that of the Class A, Class B and Class C shares
because of the absence of any service and distribution fees applicable to the
Advisor Class shares. It is expected, however, that the net asset value per
share of the classes will tend to converge immediately after the payment of
dividends, which will differ by approximately the amount of the service and
distribution fee accrual differential among the classes.
 
- --------------------------------------------------------------------------------
 
                         DIVIDENDS, OTHER DISTRIBUTIONS
                          AND FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. The Fund annually declares and pays as a
dividend all of its net investment income, if any, which includes dividends paid
to it from each Underlying Theme Fund's net investment income (if any) less
applicable expenses. The Fund also annually distributes substantially all of its
realized net capital gains, if any, which consist of (1) distributions to it
from each Underlying Theme Fund's realized net capital gains, if any, and (2)
net gains realized from the Fund's disposition of shares of the Underlying Theme
Funds (which dispositions generally are occasioned by reallocating the Fund's
assets among the Underlying Theme Funds to reflect the MCSI weightings (see
"Investment Objective and Policies") or by the need to make distributions and/
or payments of redemption proceeds in excess of available cash). The Fund may
make an additional dividend or other distribution each year if necessary to
avoid a 4% excise tax on certain undistributed income and gain.
 
Dividends and other distributions paid by the Fund with respect to all classes
of its shares are calculated in the same manner and at the same time. The per
share income dividends on Class B and Class C shares will be lower than the per
share income dividends on Class A shares as a result of the higher service and
distribution fees applicable to Class B and Class C shares; and the per share
income dividends on all such classes of shares will be lower than the per share
income dividends on the Advisor Class shares of the 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, with respect to Class
    A and Class B shares, 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, with
    respect to Class A and Class B shares, in shares
 
                               Prospectus Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
    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, with
    respect to Class A and Class B shares, in shares of the corresponding class
    of other GT Global Mutual Funds); or
 
/ / to receive dividends and other distributions in cash.
 
Automatic reinvestments in additional shares are made at net asset value without
imposition of a sales charge. IF NO ELECTION IS MADE BY A SHAREHOLDER, ALL
DIVIDENDS AND OTHER DISTRIBUTIONS WILL BE AUTOMATICALLY REINVESTED IN ADDITIONAL
FUND SHARES OF THE DISTRIBUTING CLASS. Reinvestments in another GT Global Mutual
Fund may only be directed to an account with the identical shareholder
registration and account number. These elections may be changed by a shareholder
at any time; to be effective with respect to a distribution, the shareholder or
the shareholder's broker must contact the Transfer Agent by mail or telephone at
least 15 Business Days prior to the payment date. THE FEDERAL INCOME TAX
CONSEQUENCES OF DIVIDENDS AND OTHER DISTRIBUTIONS ARE THE SAME WHETHER THEY ARE
RECEIVED IN CASH OR REINVESTED IN ADDITIONAL SHARES.
 
Any dividend or other distribution paid by the Fund has the effect of reducing
the net asset value per share on the ex-distribution date by the amount thereof.
Therefore, a dividend or other distribution paid shortly after a purchase of
shares would represent, in substance, a return of capital to the shareholder (to
the extent the distribution is paid on the shares so purchased) even though
subject to income tax, as discussed below.
 
TAXES. The Fund intends to continue to qualify for treatment as a regulated
investment company under the Code. In each taxable year that the Fund so
qualifies, the Fund (but not its shareholders) will be relieved of federal
income tax on that part of its investment company taxable income, consisting
generally of net investment income and net short-term capital gain ("taxable
income"), and net capital gain (i.e., the excess of net long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.
 
Dividends paid to the Fund from an Underlying Theme Fund's taxable income (which
may include net gains from certain foreign currency transactions) are included
in the Fund's taxable income, and dividends from the latter (whether paid in
cash or reinvested in additional shares) are taxable to the Fund's shareholders
as ordinary income to the extent of its earnings and profits. Distributions of
the Fund's net capital gain (consisting of (1) distributions to it from each
Underlying Theme Fund's net capital gain, when designated as such, and (2) net
gains realized from the Fund's disposition of an Underlying Theme Fund's shares
held for more than twelve months), 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 the distributions are 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. A notice issued by the Internal
Revenue Service in November 1997 permits the Fund to 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 requires its shareholders to
treat those portions accordingly.
 
The Fund provides federal tax information to its shareholders annually,
including information about dividends and capital gain distributions paid during
the preceding year. The information regarding capital gain distributions
designates the portions of those distributions that are subject to the different
maximum rates of tax applicable to noncorporate taxpayers' net capital gain
indicated above.
 
The Fund must withhold 31% from dividends, capital gain distributions and
redemption proceeds payable to any individuals and certain other noncorporate
shareholders who have not furnished to the Fund a correct taxpayer
identification number or a properly completed claim for exemption on Form W-8 or
W-9. Withholding at that rate also is required from dividends and capital gain
distributions payable to such shareholders who otherwise are subject to backup
withholding. Fund accounts opened via a bank wire purchase (see "How to Invest
- -- Purchases Through the Distributor") are considered to have uncertified
taxpayer identification numbers unless a completed Form W-8 or W-9 or Account
Application is received by the Transfer Agent within seven days
 
                               Prospectus Page 26
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
after the purchase. A shareholder should contact the Transfer Agent if the
shareholder is uncertain whether a proper taxpayer identification number is on
file with the Fund.
 
A redemption of Fund shares may result in taxable gain or loss to the redeeming
shareholder, depending upon whether the redemption proceeds are more or less
than the shareholder's adjusted basis for the redeemed shares (which normally
includes any initial sales charge paid on Class A shares). An exchange of Fund
shares for shares of another GT Global Mutual Fund generally will have similar
tax consequences. However, special tax rules apply when a shareholder (1)
disposes of Class A shares of the Fund through a redemption or exchange within
90 days after purchase and (2) subsequently acquires Class A shares of the Fund
or of any other GT Global Mutual Fund on which an initial sales charge normally
is imposed without paying that sales charge due to the reinstatement privilege
or exchange privilege. In these cases, any gain on the disposition of the
original Class A shares will be increased, or loss decreased, by the amount of
the sales charge paid when those shares were acquired, and that amount will
increase the adjusted basis of the shares subsequently acquired. In addition, if
Fund shares are purchased within 30 days before or after redeeming other Fund
shares (regardless of class) at a loss, all or a part of the loss will not be
deductible and instead will increase the basis of the newly purchased shares.
 
The foregoing is only a summary of some of the important federal tax
considerations generally affecting the Fund and its shareholders. See "Taxes" in
the Statement of Additional Information for a further discussion. There may be
other federal, state, local or foreign tax considerations applicable to a
particular investor. Prospective investors therefore are urged to consult their
tax advisers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund and has approved contracts with various financial organizations to
provide certain services required by the Fund. See "Trustees and Executive
Officers" in the Statement of Additional Information for a complete description
of the Trustees of the Trust.
INVESTMENT MANAGEMENT AND ADMINISTRATION. Subject to the supervision and
direction of the Trust's Board of Trustees, the Manager will ensure that the
Fund's assets are invested in the Underlying Theme Funds according to the
formula and pre-determined percentages described in the "Investment Objective
and Policies" section of this Prospectus. The Manager will determine how the
Fund's assets will be invested in short-term investments and place all purchase
and sale orders for such instruments and for the Underlying Theme Funds. The
Manager provides the following administration services to the Fund: furnishing
corporate officers and clerical staff; providing office space, services and
equipment; and supervising all matters relating to the Fund's operation. The
Manager also serves as the Fund's pricing and accounting agent. Finally, the
Manager will initially assume all costs of the Fund's operation, except for
service and distribution fees described below and non-recurring and
extraordinary expenses. The Fund, as a shareholder in the Underlying Theme
Funds, indirectly will bear its proportionate share of any investment management
fees and other expenses paid by the Underlying Theme Funds.
 
The Manager provides investment management and/or administration services to the
GT Global Mutual Funds. The Manager and its worldwide asset management
affiliates have provided investment management and/or administration services to
institutional, corporate and individual clients around the world since 1969. The
U.S. offices of the Manager are located at 50 California street, 27th Floor, San
Francisco, CA 94111 and 1166 Avenue of the Americas, New York, NY 10036.
 
The Manager and its worldwide affiliates, including LGT Bank in Liechtenstein,
compose Liechtenstein Global Trust. Liechtenstein Global Trust is a provider of
global asset management and private banking products and services to individual
and institutional investors. Liechtenstein Global Trust is controlled by the
Prince of Liechtenstein
 
                               Prospectus Page 27
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Foundation, which serves as the 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.
 
As of September 30, 1997, the Manager and its worldwide affiliates managed
approximately $61 billion in assets. In the United States, as of September 30,
1997, the Manager managed or administered approximately $9 billion of assets of
the GT Global Mutual Funds. As of September 30, 1997, assets entrusted to
Liechtenstein Global Trust totaled approximately $86 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 Mutual Funds, the Manager employs a team approach, taking
advantage of its investment resources around the world in seeking each Fund's
investment objective.
 
While the Fund will not be actively managed or have a portfolio manager, the
Underlying Theme Funds are actively managed by teams of investment
professionals. At least semi-annually the Fund will rebalance the Fund's assets
among the Underlying Theme Funds according to the MSCI weighting as of the last
business day of the preceding month.
 
DISTRIBUTION OF FUND SHARES. GT Global is the distributor of the Fund's Class A,
Class B and Class C 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, Class B and Class C
shares. GT Global reallows a portion of the sales charge on Class A shares to
broker/dealers that have sold such shares in accordance with the schedule set
forth above under "How to Invest." GT Global also pays a commission equal to
4.00% of the amount invested to broker/ dealers who sell Class B shares and pays
a commission equal to 1.00% of the amount invested to broker/dealers who sell
Class C 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 or Class C shares. In addition, with respect to all three classes of
shares, GT Global makes ongoing payments to broker/dealers for distribution and
service activities in accordance with the Rule 12b-1 plans described below.
 
GT Global, at its own expense, may provide additional promotional incentives to
broker/dealers that sell shares of the Fund and/or shares of the other GT Global
Mutual Funds. In some instances additional compensation or promotional
incentives may be offered to broker/dealers that have sold or may sell
significant amounts of shares during specified periods of time. Such
compensation and incentives may include, but are not limited to, cash,
merchandise, trips and financial assistance to broker/dealers in connection with
preapproved conferences or seminars, sales or training programs for invited
sales personnel, payment for travel expenses (including meals and lodging)
incurred by sales personnel and members of their families or other invited
guests to various locations for such seminars or training programs, seminars for
the public, advertising and sales campaigns regarding one or more of the GT
Global Mutual Funds, and/ or other events sponsored by the broker/dealers. In
addition, GT Global makes ongoing payments to brokerage firms, financial
institutions (including banks) and others that facilitate the administration and
servicing of shareholder accounts.
 
Under a plan of distribution adopted by the Trust's Board of Trustees pursuant
to Rule 12b-1 under the 1940 Act, with respect to the Fund's Class A shares
("Class A Plan"), the Fund may pay GT Global a service fee at the annualized
rate of up to 0.25% of the average daily net assets of the Fund's Class A shares
for its expenditures incurred in servicing and maintaining shareholder accounts,
and may pay GT Global a distribution fee at the annualized rate of up to 0.50%
of the average daily net assets of the Fund's Class A shares, less any amounts
paid by the Fund as the aforementioned service fee for its expenditures 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 separate plans of distribution adopted with respect to the Fund's
Class B and Class C shares ("Class B Plan" and "Class C Plan," respectively),
the Fund may pay GT Global a service fee at the annualized rate of up to 0.25%
of the average daily net assets of the Fund's Class B and Class C shares for its
expenditures incurred in servicing and maintaining shareholder accounts, and may
 
                               Prospectus Page 28
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 and Class C shares for its
expenditures incurred in providing services as distributor. Expenses incurred
under the Class B Plan and Class C Plan in excess of 1.00% annually may be
carried forward for reimbursement in subsequent years as long as such Plan
continues in effect.
 
GT Global's service and distribution expenses include the payment of ongoing
commissions; the cost of any additional 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 under the Class B Plan and the Class C Plan include
payment of initial sales commissions to broker/ dealers and interest on any
unreimbursed amounts carried forward thereunder.
 
The Glass-Steagall Act and other applicable laws, among other things, generally
prohibit federally chartered or supervised banks from engaging in the business
of underwriting or distributing securities. Accordingly, GT Global intends to
engage banks (if at all) only to perform administrative and shareholder
servicing functions. If a bank 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
 
- --------------------------------------------------------------------------------
 
SPECIAL SERVICING AGREEMENT. Until the Special Servicing Agreement described
below is entered into, the Manager will pay all the expenses of the Fund,
excluding service and distribution fees and certain non-recurring and
extraordinary expenses. Expenses initially paid by the Manager will include fees
and expenses of the Fund's accounting agent; legal, auditing and accounting
expenses; taxes; fees and expenses of the Transfer Agent; fees and expenses of
registering or qualifying the Fund's shares for sale; fees and expenses of
Trustees, officers and employees of the Trust who are not affiliated with the
Manager; the cost of printing and distributing reports and notices to existing
shareholders; and fees and expenses incurred in connection with membership in
investment company organizations.
 
An exemptive application has been filed with the SEC requesting relief from
certain provisions of the 1940 Act to permit the Fund, the Manager, the
Underlying Theme Funds and the Transfer Agent to enter into a Special Servicing
Agreement ("Agreement"). A private letter ruling has also been requested from
the Internal Revenue Service concerning this arrangement. If relief is obtained,
all the Fund's expenses except for service and distribution fees and certain
non-recurring and extraordinary expenses will be paid for in accordance with the
Agreement. Under the Agreement, to the extent that the aggregate expenses of the
Fund are less than the estimated savings to the Underlying Theme Funds from the
operation of the Fund, each Underlying Theme Fund will bear those expenses in
proportion to the average daily value of its shares owned by the Fund and/or the
number of shareholder accounts at the Fund. The estimated savings are expected
to result from the reduction of the Underlying Theme Funds' shareholder
servicing costs due to the elimination of separate shareholder accounts that
either currently are or have potential to be invested in the Underlying Theme
Funds. The estimated savings produced by the operation of the Fund may offset
most, if not all, the expenses incurred by the Fund other than service and
distribution fees. To the extent that the Fund's expenses exceed the aggregate
financial benefits to the Underlying Theme Funds, the Manager will pay that
excess.
 
CONFIRMATIONS AND REPORTS TO SHAREHOLDERS. Each time a transaction is made that
affects a shareholder's account in the Fund, the shareholder will receive from
the Transfer Agent a confirmation statement reflecting the transaction.

Investment Plan, Systematic Withdrawal

Plan and automatic dividend reinvestment program may be provided quarterly.
Shortly after the end of the Fund's fiscal year on December 31 and fiscal
half-year on June 30 of each year, shareholders receive an annual and semiannual
report, respectively. In addition, the federal income status of distributions
made by the Fund to shareholders is reported after the end of each calendar year
on Form 1099-DIV. Under certain circumstances, duplicate mailings of the
foregoing reports to the same household may be consolidated.
 
ORGANIZATION OF THE TRUST. The Trust was organized as a Massachusetts business
trust on August 26, 1996. The Trust currently consists of one series. From time
to time, the Trust may establish other series, each holding a distinct
investment portfolio and issuing a distinct series of the Trust's shares. Shares
of each series are entitled to one vote per share (with proportional voting for
fractional shares) and are transferable. Shareholders have no preemptive or
conversion rights.
 
If any additional series of the Trust are established, on any matter submitted
to a vote of shareholders, shares of each series will be voted by its
shareholders individually when the matter affects the specific interest of that
series only, such as approval of its investment management arrangements. The
shares of the Trust's series would be voted in the aggregate on other matters,
such as the election of Trustees and ratification of the selection by the Board
of Trustees of the Trust's independent accountants.
 
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. The Fund would be required to hold a shareholders'
meeting if at any time less than a majority of the Trustees holding office had
been elected by shareholders. Trustees continue to hold office until their
successors are elected and have qualified. Fund shares do not have cumulative
voting rights, which means that the holders of a majority of the shares voting
for the election of Trustees can elect all the Trustees. A Trustee may be
removed upon a majority vote of the shareholders qualified to vote in the
election. Shareholders holding 10% of the Trust's outstanding voting shares may
call a meeting of shareholders for the purpose of voting upon the question of
removal of any Trustee or for any other purpose. The 1940 Act requires the Trust
to assist shareholders in calling such a meeting.
 
Pursuant to the Trust's Declaration of Trust, the Trust may issue an unlimited
number of shares of the Fund, including an unlimited number of Class A, Class B,
Class C and Advisor Class shares of the Fund. Each share of the Fund has no par
value, represents an equal proportionate interest in the Fund with other Fund
shares and is entitled to such dividends and other distributions out of the
income earned and gain realized on the assets belonging to the Fund as may be
declared at the discretion of the Board of Trustees. Each Class A, Class B,
Class C and Advisor Class share of the Fund is equal in earnings, assets and
voting privileges to each other share of the Fund, except that each class has
exclusive voting rights with respect to its distribution plan and bears the
expenses, if any, related to the distribution of its shares. Fund shares, when
issued, are fully paid and nonassessable.
 
SHAREHOLDER INQUIRIES. Shareholder inquiries may be made by calling the Fund
toll-free at (800) 223-2138 or by writing to the Fund at 50 California Street,
27th Floor, San Francisco, CA 94111.
 
TRANSFER AGENT. Shareholder servicing, reporting and general transfer agent
functions for the Fund are performed by GT Global Investor Services, Inc. The
Transfer Agent is an affiliate of the Manager and GT Global, a subsidiary of
Liechtenstein Global Trust and maintains offices at California Plaza, 2121 N.
California Boulevard, Suite 450, Walnut Creek, CA 94596.
 
CUSTODIAN. State Street Bank and Trust Company, 225 Franklin Street, Boston, MA
02110, is custodian of the assets of the Fund.

N.W., Washington, D.C. 20036-1800, acts as counsel to the Trust and to the Fund.
Kirkpatrick & Lockhart LLP also acts as counsel to the Manager, GT Global and
the Transfer Agent in connection with other matters.
 
INDEPENDENT ACCOUNTANTS. The Fund's independent accountants are Coopers &
Lybrand L.L.P., One Post Office Square, Boston, MA 02109. Coopers & Lybrand
L.L.P. conducts an annual audit of the Fund, assists in the preparation of the
Fund's federal and state income tax returns, and consults with the Trust and the
Fund as to matters of accounting, regulatory filings, and federal and state
income taxation.

                                  PERFORMANCE
 
- --------------------------------------------------------------------------------
 
FUND PERFORMANCE INFORMATION. The Fund, from time to time, may include
information on its investment results and/or comparisons of its investment
results to various unmanaged indices or results of other mutual funds or groups
of mutual funds in advertisements, sales literature or reports furnished to
present or prospective shareholders.
 
In such materials, the Fund may quote its average annual total return
("Standardized Return"). Standardized Return is calculated separately for each
class of shares of the Fund. Standardized Return shows percentage rates
reflecting the average annual change in the value of an assumed investment in
the Fund at the end of a one-year period and at the end of five- and ten-year
periods, reduced by the maximum applicable sales charge imposed on sales of Fund
shares. If a one-, five- and/or ten-year period has not yet elapsed, data will
be provided as of the end of a shorter period corresponding to the life of the
Fund. Standardized Return assumes the reinvestment of all dividends and other
distributions.
 
In addition, in order to more completely represent the Fund's performance or
more accurately compare the performance to other measures of investment return,
the Fund also may include other total return performance data ("Non-Standardized
Return") in advertisements, sales literature and shareholder reports.
Non-Standardized Return reflects percentage rates of return encompassing all
elements of return (i.e., income and capital appreciation or depreciation) and
assumes reinvestment of all dividends and other distributions. Non-Standardized
Return may be quoted for the same or different periods as those for which
Standardized Return is quoted; it may consist of an aggregate or average annual
percentage rate of return, actual year-by-year rates or any combination thereof.
Non-Standardized Return may or may not take sales charges into account;
performance data calculated without taking the effect of sales charges into
account will be higher than data including the effect of such charges.
 
The Fund's performance data will reflect past performance and will not
necessarily be indicative of future results. The Fund's investment results will
vary from time to time depending upon market conditions and the composition of
the Underlying Theme Funds' portfolios. These factors and possible differences
in calculation methods should be considered when comparing the Fund's investment
results with those published for other investment companies, other investment
vehicles and unmanaged indices. The Fund's results also should be considered
relative to the risks associated with its investment objective and policies. See
"Investment Results" in the Statement of Additional Information.
 
UNDERLYING THEME FUND PERFORMANCE. The Fund has a limited history and therefore
a limited performance record. Thus, the performance shown below is not the
performance of the Fund, but instead reflects the performance of the Underlying
Theme Funds. The following table shows the average annual total returns of Class
A and Class B shares of each Underlying Theme Fund for the most recent one- and
five-year periods (as applicable) and for the life of the Underlying Theme
Funds. The performance information reflects deduction of the maximum applicable
sales charges. Returns would be higher if these charges were not reflected. The
Fund invests in the Advisor Class shares of the Underlying Theme Funds, which
are not subject to sales charges and distribution and service fees. However,
Class A and Class B shares of the Fund are subject to their own sales charges
and distribution and service fees.

                            INVESTMENT OBJECTIVE AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT POLICIES OF THE FUND
The following supplements the information contained in the Prospectus concerning
the investment policies of the Fund.
 
U.S. GOVERNMENT SECURITIES. The Fund may invest in various direct obligations of
the U.S. Treasury and obligations issued or guaranteed by the U.S. government or
one  of  its  agencies  or  instrumentalities  (collectively,  "U.S.  government
securities"). Among the U.S. government securities that may be held by the  Fund
are  securities that are  supported by the  full faith and  credit of the United
States; securities that are supported by the right of the issuer to borrow  from
the U.S. Treasury; and securities that are supported solely by the credit of the
instrumentality.
 
REPURCHASE   AGREEMENTS.  The  Fund  may  invest  in  repurchase  agreements.  A
repurchase agreement is  a transaction  in which the  Fund purchases  securities
from a bank or recognized securities dealer and simultaneously commits to resell
the  securities to the bank or dealer on  an agreed-upon date or upon demand and
at a price reflecting a market rate of interest unrelated to the coupon rate  or
maturity  of  the  purchased  securities.  The  Fund  maintains  custody  of the
underlying securities prior  to their  repurchase; thus, the  obligation of  the
bank  or dealer to pay the repurchase price on the date agreed to is, in effect,
secured by such securities. If  the value of these  securities is less than  the
repurchase price, plus any agreed-upon additional amount, the other party to the
agreement must provide additional collateral so that at all times the collateral
is  at  least equal  to the  repurchase price,  plus any  agreed-upon additional
amount. The difference between the total  amount to be received upon  repurchase
of  the securities and the  price that was paid by  the Fund upon acquisition is
accrued as  interest  and included  in  its net  investment  income.  Repurchase
agreements  carry  certain  risks  not  associated  with  direct  investments in
securities, including possible declines  in the market  value of the  underlying
securities  and delays and costs to the Fund  if the other party to a repurchase
agreement becomes insolvent.
 
INVESTMENT POLICIES OF THE UNDERLYING THEME FUNDS
The following supplements the information contained in the Prospectus concerning
the investment  policies and  limitations of  the Underlying  Theme Funds.  More
information  about the investment  policies and restrictions  and the investment
limitations of each Underlying Theme Fund  is set forth in the Underlying  Theme
Funds' prospectus and statement of additional information.
 
The Underlying Theme Funds are diversified series of G.T. Investment Funds, Inc.
(the  "Company"), a  registered open-end  management investment  company. The GT
Global Consumer  Products and  Services Fund  ("Consumer Products  and  Services
Fund"), GT Global Financial Services Fund ("Financial Services Fund"), GT Global
Infrastructure  Fund ("Infrastructure  Fund"), and  GT Global  Natural Resources
Fund ("Natural Resources Fund") (each,  a "Feeder Fund," and, collectively,  the
"Feeder Funds") each invests all of its investable assets in the Global Consumer
Products  and Services  Portfolio, Global  Financial Services  Portfolio, Global
Infrastructure Portfolio,  and  Global  Natural  Resources  Portfolio  (each,  a
"Portfolio," and, collectively, the "Portfolios"), respectively.
 
Each  Portfolio is  a subtrust (a  "series") of Global  Investment Portfolio (an
open-end management investment  company) with  an investment  objective that  is
identical  to  that of  its corresponding  Underlying  Theme Fund.  Whenever the
phrase "all of the Underlying Theme Fund's investable assets" is used herein, it
means that the  only investment securities  held by  a Feeder Fund  will be  its
interest  in  its  corresponding  Portfolio.  A  Feeder  Fund  may  withdraw its
investment in its corresponding Portfolio at any time, if the Company's Board of
Directors determines that it is in the best interests of the Feeder Fund and its
shareholders to do so. Upon any such withdrawal, a Feeder Fund's assets would be
invested in  accordance  with  the  investment  policies  of  its  corresponding
Portfolio described below and in the Underlying Theme Funds' prospectus.
 
The  investment objective of  each Feeder Fund is  long-term capital growth. The
investment objectives of the GT Global Health Care Fund ("Health Care Fund") and
the GT Global Telecommunications Fund ("Telecommunications Fund") are  long-term
capital  appreciation and long-term capital growth, respectively. The Portfolios
and the Health Care Fund and the Telecommunications Fund, together, are referred
to herein as the "Underlying Theme Portfolios."
 
                   Statement of Additional Information Page 2
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
SELECTION OF EQUITY INVESTMENTS.  With respect to  the Global Natural  Resources
Portfolio,  the Manager  has identified four  areas that it  expects will create
investment opportunities: (i)  improving supply/demand  fundamentals, which  may
result  in higher  commodity prices;  (ii) privatization  of state-owned natural
resource businesses; (iii) management which can improve production  efficiencies
without  correspondingly increasing commodity prices; and (iv) service companies
with emerging technologies  that can enhance  productivity or reduce  production
costs.  Of course,  there is  no certainty that  these factors  will produce the
anticipated results.
 
With respect to  the Telecommunications  Fund, the Manager  has identified  four
areas  that it expects will create investment opportunities: (i) deregulation of
companies in  the industry,  which  will allow  competition to  promote  greater
efficiencies;  (ii) privatization of  state-owned telecommunications businesses;
(iii) development of infrastructure in underdeveloped countries and upgrading of
services in other countries;  and (iv) emerging  technologies that will  enhance
productivity  and reduce  costs in  the telecommunications  industry. Of course,
there is no certainty that these factors will produce the anticipated results.
 
There may  be times  when, in  the opinion  of the  Manager, prevailing  market,
economic  or  political  conditions  warrant  reducing  the  proportion  of  the
Underlying Theme Portfolios' assets invested in equity securities and increasing
the proportion held in cash  (U.S. dollars, foreign currencies or  multinational
currency  units) or  invested in  debt securities  or high  quality money market
instruments  issued  by  corporations,  or  the  United  States,  or  a  foreign
government.  A portion of each Underlying Theme Portfolio's assets normally will
be held  in cash  (U.S. dollars,  foreign currencies  or multinational  currency
units)  or invested in foreign or domestic high quality money market instruments
pending investment of proceeds from new sales of Underlying Theme Fund shares to
provide for ongoing expenses and to satisfy redemptions.
 
For  each  Underlying  Theme  Portfolio's  investment  purposes,  an  issuer  is
typically  considered as located in a particular  country if it (a) is organized
under the laws of or  has its principal office in  a particular country, or  (b)
normally  derives  50% or  more  of its  total  revenues from  business  in that
country, provided  that, in  the  Manager's view,  the  value of  such  issuer's
securities  will tend to reflect such  country's development to a greater extent
than developments elsewhere. However, these  are not absolute requirements,  and
certain  companies incorporated  in a particular  country and  considered by the
Manager to be located in that country may have substantial foreign operations or
subsidiaries and/or export sales exceeding in  size the assets or sales in  that
country.
 
In  certain  countries,  governmental  restrictions  and  other  limitations  on
investment may affect a Underlying Theme  Portfolio's ability to invest in  such
countries. In addition, in some instances only special classes of securities may
be  purchased by  foreigners and  the market  prices, liquidity  and rights with
respect to those securities may vary from shares owned by nationals. The Manager
is not aware at this time of the existence of any investment or exchange control
regulations which might  substantially impair the  operations of the  Underlying
Theme  Portfolios as  described in  the Underlying  Theme Funds'  prospectus and
statement of additional  information. Restrictions may  in the future,  however,
make it undesirable to invest in certain countries. None of the Underlying Theme
Portfolios  has a present intention of  making any significant investment in any
country or stock market in which the Manager considers the political or economic
situation to threaten  a Underlying  Theme Portfolio with  substantial or  total
loss of its investment in such country or market.
 
INVESTMENTS  IN OTHER INVESTMENT COMPANIES.  Each Underlying Theme Portfolio may
invest in the securities of investment  companies within the limitations of  the
Investment  Company Act of 1940, as  amended (the "1940 Act"). These limitations
currently provide that, in general,  an Underlying Theme Portfolio may  purchase
shares  of  an investment  company unless  (a)  such a  purchase would  cause an
Underlying Theme Portfolio to  own in the  aggregate more than  3% of the  total
outstanding  voting stock of the investment company or (b) such a purchase would
cause the Underlying Theme Portfolio to have more than 5% of its assets invested
in the  investment  company or  more  than 10%  of  its assets  invested  in  an
aggregate  of all such  investment companies. The  foregoing restrictions do not
apply to the investment of the  Feeder Funds in their corresponding  Portfolios.
Investment  in  closed-end  investment  companies  may  involve  the  payment of
substantial premiums above  the value of  such companies' portfolio  securities.
Each  Underlying Theme  Portfolio does not  intend to invest  in such investment
companies unless, in the judgment of the Manager, the potential benefits of such
investments justify the payment of any  applicable premiums. The return on  such
securities  will be reduced  by operating expenses  of such companies, including
payments to the investment managers of those investment companies.
 
DEPOSITORY RECEIPTS.  An  Underlying  Theme Portfolio  may  hold  securities  of
foreign  issuers in the form of  American Depository Receipts ("ADRs"), American
Depository Shares ("ADSs")  and European Depository  Receipts ("EDRs") or  other
securities  convertible  into  securities  of  eligible  foreign  issuers. These
securities may  not necessarily  be  denominated in  the  same currency  as  the
securities  for which they may be exchanged.  ADRs and ADSs are typically issued
by an  American bank  or  trust company  and  evidence ownership  of  underlying
securities issued by a foreign corporation. EDRs,
 
                   Statement of Additional Information Page 3
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
which are sometimes referred to as Continental Depository Receipts ("CDRs"), are
issued  in Europe  typically by foreign  banks and trust  companies and evidence
ownership of either foreign or domestic securities. Generally, ADRs and ADSs  in
registered  form are  designed for  use in U.S.  securities markets  and EDRs in
bearer form are designed for use in European securities markets. For purposes of
each Underlying  Theme  Portfolio's  investment policies,  an  Underlying  Theme
Portfolio's  investments in ADRs, ADSs and EDRs will be deemed to be investments
in the equity securities representing  securities of foreign issuers into  which
they may be converted.
 
ADR  facilities may be established as either "unsponsored" or "sponsored." While
ADRs issued under these  two types of facilities  are in some respects  similar,
there  are distinctions between  them relating to the  rights and obligations of
ADR holders and the practices of market participants. A depository may establish
an unsponsored  facility  without  participation by  (or  even  necessarily  the
acquiescence  of) the issuer of the deposited securities, although typically the
depository requests a  letter of  non-objection from  such issuer  prior to  the
establishment  of the facility.  Holders of unsponsored  ADRs generally bear all
the costs  of such  facilities. The  depository usually  charges fees  upon  the
deposit  and withdrawal of the deposited securities, the conversion of dividends
into  U.S.  dollars,  the  disposition   of  non-cash  distributions,  and   the
performance  of  other  services.  The  depository  of  an  unsponsored facility
frequently is  under  no  obligation to  distribute  shareholder  communications
received  from the issuer of the  deposited securities or to pass-through voting
rights to ADR  holders in  respect of  the deposited  securities. Sponsored  ADR
facilities  are created in generally the  same manner as unsponsored facilities,
except that  the  issuer of  the  deposited  securities enters  into  a  deposit
agreement  with the  depository. The deposit  agreement sets out  the rights and
responsibilities of  the  issuer,  the  depository and  the  ADR  holders.  With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository),  although ADR holders continue to bear certain other costs (such as
deposit and withdrawal fees).  Under the terms  of most sponsored  arrangements,
depositories  agree  to distribute  notices of  shareholder meetings  and voting
instructions, and to provide shareholder communications and other information to
the ADR holders at the  request of the issuer  of the deposited securities.  The
Underlying Theme Portfolios may invest in both sponsored and unsponsored ADRs.
 
WARRANTS  OR RIGHTS. Warrants or  rights may be acquired  by an Underlying Theme
Portfolio in  connection with  other securities  or separately  and provide  the
Underlying  Theme Portfolio  with the  right to purchase  at a  later date other
securities of the issuer.
 
LENDING OF UNDERLYING THEME PORTFOLIO  SECURITIES. For the purpose of  realizing
additional income, each Underlying Theme Portfolio may make secured loans of its
securities  holdings  amounting  to  not  more than  30%  of  its  total assets.
Securities loans are made to broker/dealers or institutional investors  pursuant
to  agreements requiring that the loans be continuously secured by collateral at
least equal at all times  to the value of the  securities lent plus any  accrued
interest,  "marked to market" on a  daily basis. The Underlying Theme Portfolios
may pay reasonable administrative and custodial fees in connection with the loan
of their securities.  While the  securities loan is  outstanding, an  Underlying
Theme  Portfolio  will continue  to receive  the equivalent  of the  interest or
dividends paid by  the issuer  on the  securities, as  well as  interest on  the
investment  of the collateral  or a fee  from the borrower.  An Underlying Theme
Portfolio will have a right to call  each loan and obtain the securities  within
the  stated settlement period.  An Underlying Theme Portfolio  will not have the
right to vote equity securities while they are being lent, but it may call in  a
loan  in anticipation of  any important vote.  Loans will only  be made to firms
deemed by the 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. The risks in lending Underlying Theme Portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional  collateral or  in recovery  of the  securities and  possible loss of
rights in the collateral should the borrower fail financially.
 
COMMERCIAL  BANK  OBLIGATIONS.  For  the  purposes  of  each  Underlying   Theme
Portfolio's investment policies with respect to bank obligations, obligations of
foreign  branches of  U.S. banks  and of  foreign banks  are obligations  of the
issuing bank and may be general obligations of the parent bank. Such obligations
may, however, be limited by the terms of a specific obligation and by government
regulation. As with investments in  non-U.S. securities in general,  investments
in  the obligations of foreign  branches of U.S. banks  and of foreign banks may
subject each Underlying Theme Portfolio  to investment risks that are  different
in  some  respects from  those of  investments in  obligations of  U.S. issuers.
Although each  Underlying Theme  Portfolio  will typically  acquire  obligations
issued  and supported by the credit of U.S. or foreign banks having total assets
at the time of purchase of $1 billion or more, this $1 billion figure is not  an
investment  policy or  restriction of each  Underlying Theme  Portfolio. For the
purposes of calculation with respect to the  $1 billion figure, the assets of  a
bank will be deemed to include the assets of its U.S. and non-U.S. branches.

REPURCHASE  AGREEMENTS.  A repurchase  agreement is  a  transaction in  which an
Underlying Theme  Portfolio  purchases  securities from  a  bank  or  recognized
securities  dealer and  simultaneously commits to  resell the  securities to the
bank or dealer on an agreed-upon date or upon demand and at a price reflecting a
market rate  of  interest  unrelated to  the  coupon  rate or  maturity  of  the
purchased  securities. Although  repurchase agreements  carry certain  risks not
associated with direct investments in securities, including possible decline  in
the  market  value of  the underlying  securities  and delays  and costs  to the
Underlying Theme  Portfolio  if the  other  party to  the  repurchase  agreement
becomes   bankrupt,  the  Underlying  Theme  Portfolios  intend  to  enter  into
repurchase agreements only  with banks and  dealers believed by  the Manager  to
present  minimal credit risks  in accordance with  guidelines established by the
Company's Board of Directors or Global Investment Portfolio's Board of  Trustees
(each  a "Board"  and, collectively, the  "Boards"), as  applicable. The Manager
will review  and monitor  the creditworthiness  of such  institutions under  the
applicable Board's general supervision.
 
Each  Underlying  Theme  Portfolio  will invest  only  in  repurchase agreements
collateralized at all times in an amount at least equal to the repurchase  price
plus  accrued interest. To  the extent that  the proceeds from  any sale of such
collateral upon a  default in the  obligation to repurchase  were less than  the
repurchase  price, an  Underlying Theme  Portfolio would  suffer a  loss. If the
financial institution that is  party to the  repurchase agreement petitions  for
bankruptcy  or  otherwise becomes  subject  to bankruptcy  or  other liquidation
proceedings, there  may  be  restrictions on  an  Underlying  Theme  Portfolio's
ability to sell the collateral and it could suffer a loss. However, with respect
to  financial  institutions  whose  bankruptcy  or  liquidation  proceedings are
subject to the U.S. Bankruptcy Code, each Underlying Theme Portfolio intends  to
comply  with provisions under such code that would allow the immediate resale of
such  collateral.  Each  Underlying  Theme  Portfolio  will  not  enter  into  a
repurchase  agreement with a maturity  of more than seven  days if, as a result,
more than 15% of the value of its  net assets (except for the Health Care  Fund,
more  than 10%  of the  value of  its total  assets) would  be invested  in such
repurchase agreements and other illiquid investments.
 
BORROWING,  REVERSE  REPURCHASE   AGREEMENTS  AND   "ROLL"  TRANSACTIONS.   Each
Underlying  Theme Portfolio's  borrowings will not  exceed 33 1/3%  of its total
assets, I.E., the Underlying  Theme Portfolio's total assets  at all times  will
equal  at  least  300%  of  the  amount  of  outstanding  borrowings.  If market
fluctuations in the value of an Underlying Theme Portfolio's securities holdings
or other factors cause the ratio  of its total assets to outstanding  borrowings
to  fall below 300%, within three days  (excluding Sundays and holidays) of such
event that  Underlying  Theme  Portfolio  may  be  required  to  sell  portfolio
securities  to restore the  300% asset coverage, even  though from an investment
standpoint such sales might be disadvantageous. Each Underlying Theme  Portfolio
may also borrow up to 5% of its total assets for temporary or emergency purposes
other  than to meet redemptions. Any  borrowing by an Underlying Theme Portfolio
may cause greater fluctuation in the value of its shares than would be the  case
if it did not borrow.
 
Each  Underlying Theme Portfolio's fundamental  investment limitations permit it
to  borrow  money  for  leveraging  purposes.  However,  each  Underlying  Theme
Portfolio  (except the Health Care Fund)  is currently prohibited, pursuant to a
non-fundamental investment policy,  from borrowing  money in  order to  purchase
securities.  Nevertheless,  this policy  may  be changed  in  the future  by the
applicable Board.  If an  Underlying  Theme Portfolio  employs leverage  in  the
future, it would be subject to certain additional risks. Use of leverage creates
an  opportunity for greater growth of capital but would exaggerate any increases
or decreases in  the net asset  value of a  Feeder Fund or  an Underlying  Theme
Portfolio.  When the income and gains  on securities purchased with the proceeds
of  borrowings  exceed  the  costs  of  such  borrowings,  an  Underlying  Theme
Portfolio's  earnings or  a Feeder Fund's  net asset value  will increase faster
than otherwise would be the case; conversely,  if such income and gains fail  to
exceed  such costs, an Underlying Theme  Portfolio's earnings or a Feeder Fund's
net asset value would decline faster than would otherwise be the case.
 
Each Underlying Theme Portfolio may enter into reverse repurchase agreements.  A
reverse  repurchase agreement is a borrowing transaction in which the Underlying
Theme Portfolio transfers possession of securities  to another party, such as  a
bank  or  broker/dealer,  in  return  for cash,  and  agrees  to  repurchase the
securities in the  future at an  agreed upon price,  which includes an  interest
component.  Each Underlying Theme Portfolio may  also engage in "roll" borrowing
transactions, which involve the sale of Government National Mortgage Association
certificates or  other securities  together  with a  commitment (for  which  the
Underlying  Theme  Portfolio may  receive a  fee) to  purchase similar,  but not
identical, securities at  a future  date. Each Underlying  Theme 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. Each Underlying Theme Portfolio  (except the Health Care Fund) may
make short  sales of  securities. A  short sale  is a  transaction in  which  an
Underlying  Theme Portfolio  sells a  security in  anticipation that  the market
price of that  security will  decline. An  Underlying Theme  Portfolio may  make
short    sales   (i)    as   a   form    of   hedging    to   offset   potential
 
                   Statement of Additional Information Page 5
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
declines in long positions in securities  it owns, or anticipates acquiring,  or
in  similar  securities,  and  (ii)  in order  to  maintain  flexibility  in its
securities holdings.
 
When an Underlying Theme Portfolio makes a short sale of a security it does  not
own,  it must borrow the security sold short and deliver it to the broker/dealer
or other intermediary through which it made the short sale. The Underlying Theme
Portfolio may have to pay a fee  to borrow particular securities and will  often
be obligated to pay over any payments received on such borrowed securities.
 
An Underlying Theme Portfolio's obligation to replace the borrowed security when
the  borrowing is called or expires will be secured by collateral deposited with
the intermediary.  The  Underlying Theme  Portfolio  will also  be  required  to
deposit  collateral with its custodian to the  extent, if any, necessary so that
the value of both collateral deposits in the aggregate is at all times equal  to
at  least 100% of the current market value of the security sold short. Depending
on arrangements made with the intermediary  from which it borrowed the  security
regarding  payment of any amounts received by it on such security, an Underlying
Theme Portfolio  may  not  receive  any payments  (including  interest)  on  its
collateral deposited with such intermediary.
 
If  the price of the security sold short increases between the time of the short
sale and the time an Underlying Theme Portfolio replaces the borrowed  security,
it  will incur a loss;  conversely, if the price  declines, the Underlying Theme
Portfolio will  realize  a  gain. Any  gain  will  be decreased,  and  any  loss
increased, by the transaction costs associated with the transaction. Although an
Underlying  Theme Portfolio's gain is limited by  the price at which it sold the
security short, its potential loss theoretically is unlimited.
 
No Underlying Theme Portfolio will make a short sale if, after giving effect  to
the sale, the market value of the securities sold short exceeds 25% of the value
of  its total assets or  its aggregate short sales of  the securities of any one
issuer exceed the lesser of 2% of its net assets or 2% of the securities of  any
class of the issuer. Moreover, an Underlying Theme Portfolio may engage in short
sales only with respect to securities listed on a national securities exchange.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use by  the Underlying Theme  Portfolios 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  an Underlying Theme
    Portfolio entered into a short hedge because the Manager projected a decline
    in the price of  a security in the  Underlying Theme Portfolio's  portfolio,
    and  the  price  of that  security  increased  instead, the  gain  from that
    increase might be wholly or  partially offset by a  decline in the price  of
    the  hedging instrument.  Moreover, if the  price of  the hedging instrument
    declined by  more  than the  increase  in the  price  of the  security,  the
    Underlying
 
                   Statement of Additional Information Page 6
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
    Theme  Portfolio could  suffer a loss.  In either such  case, the Underlying
    Theme Portfolio would have been  in a better position  had it not hedged  at
    all.
 
        (4)  As described below, an Underlying Theme Portfolio might be required
    to maintain assets as "cover,"  maintain segregated accounts or make  margin
    payments  when it  takes positions  in instruments  involving obligations to
    third parties  (I.E.,  instruments other  than  purchased options).  If  the
    Underlying  Theme Portfolio were  unable to close out  its positions in such
    instruments, it might  be required to  continue to maintain  such assets  or
    accounts  or make such  payments until the position  expired or matured. The
    requirements might impair the Underlying Theme Portfolio's ability to sell a
    portfolio security or make an investment  at a time when it would  otherwise
    be favorable to do so, or require that the Underlying Theme Portfolio sell a
    portfolio   security  at  a  disadvantageous   time.  The  Underlying  Theme
    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 Underlying
    Theme Portfolio.
 
WRITING CALL OPTIONS
Each Underlying Theme  Portfolio may  write (sell) call  options on  securities,
indices and currencies. Call options generally will be written on securities and
currencies  that, in the  opinion of the  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 Underlying Theme Portfolios.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
style) or on (European style) a certain  date (the expiration date). So long  as
the  obligation of  the writer  of a  call option  continues, he  or she  may be
assigned an exercise  notice, requiring  him or  her to  deliver the  underlying
security  or currency  against payment  of the  exercise price.  This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer  effects  a closing  purchase  transaction by  purchasing  an  option
identical to that previously sold.
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on the basis of investment considerations consistent with  each
Underlying  Theme Portfolio's investment objective.  When writing a call option,
an Underlying  Theme  Portfolio,  in  return  for  the  premium,  gives  up  the
opportunity  for  profit from  a price  increase in  the underlying  security or
currency above the exercise price, and retains the risk of loss should the price
of the  security  or  currency  decline.  Unlike  one  who  owns  securities  or
currencies  not  subject to  an  option, an  Underlying  Theme Portfolio  has no
control over  when it  may be  required  to sell  the underlying  securities  or
currencies,  since  most options  may  be exercised  at  any time  prior  to the
option's expiration. If  a call option  that an Underlying  Theme Portfolio  has
written  expires, it 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 Underlying Theme Portfolio will realize a gain or loss from the sale of  the
underlying  security  or currency,  which  will be  increased  or offset  by the
premium received. The Underlying Theme Portfolios do not consider a security  or
currency  covered by a call option to be "pledged" as that term is used in their
policies that limit the pledging or mortgaging of their assets.
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option will be exercised and an Underlying Theme Portfolio
will be obligated  to sell  the security  or currency  at less  than its  market
value.
 
The  premium  that an  Underlying Theme  Portfolio receives  for writing  a call
option is deemed to constitute  the market value of  an option. The premium  the
Underlying Theme Portfolio will receive from writing a call option will reflect,
among  other things, the current market  price of the underlying investment, the
relationship of the exercise  price to such market  price, the historical  price
volatility of the underlying investment, and the length of the option period. In
determining whether a particular call option should be written, the 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  an Underlying  Theme
Portfolio  to write another  call option on the  underlying security or currency
with either a different exercise price or expiration date, or both.
 
                   Statement of Additional Information Page 7
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
Each Underlying Theme Portfolio  will pay transaction  costs in connection  with
the  writing  of  options  and  in  entering  into  closing  purchase contracts.
Transaction costs relating to  options activity are  normally higher than  those
applicable to purchases and sales of portfolio securities.
 
The  exercise price of the  options may be below, equal  to or above the current
market values of the  underlying securities, indices or  currencies at the  time
the  options are written. From  time to time, an  Underlying Theme Portfolio may
purchase an underlying security or currency for delivery in accordance with  the
exercise of an option, rather than delivering such security or currency from its
portfolio. In such cases, additional costs will be incurred.
 
An  Underlying Theme  Portfolio will  realize a  profit or  loss from  a closing
purchase  transaction  if  the  cost  of  the  transaction  is  less  or   more,
respectively,  than  the  premium  received  from  writing  the  option. Because
increases in the market price of a call option generally will reflect  increases
in  the market price of the underlying  security or currency, any loss resulting
from the 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 an Underlying
Theme Portfolio.
 
WRITING PUT OPTIONS
Each Underlying Theme Portfolio may write put options on securities, indices and
currencies. A put option gives  the purchaser of the  option the right to  sell,
and  the  writer (seller)  the  obligation to  buy,  the underlying  security or
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style) the  expiration date.  The operation  of put  options in other
respects, including their related risks and rewards, is substantially  identical
to that of call options.
 
An Underlying Theme Portfolio generally would write put options in circumstances
where the Manager wishes to purchase the underlying security or currency for the
Underlying  Theme Portfolio's holdings at a  price lower than the current market
price of the security or currency. In such event, an Underlying Theme  Portfolio
would  write a  put option  at an  exercise price  that, reduced  by the premium
received on the option, reflects the lower price it is willing to pay. Since the
Underlying Theme Portfolio  would also  receive interest on  debt securities  or
currencies  maintained to cover the exercise price of the option, this technique
could be used to  enhance current return during  periods of market  uncertainty.
The  risk in such a transaction would be that the market price of the underlying
security or currency  would decline below  the exercise price  less the  premium
received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected  that the  put option  will  be exercised  and an  Underlying Theme
Portfolio will be obligated to purchase the security or currency at greater than
its market value.
 
PURCHASING PUT OPTIONS
Each Underlying Theme Portfolio may purchase put options on securities,  indices
and  currencies. As the  holder of a  put option, an  Underlying Theme Portfolio
would have the right to sell the underlying security or currency at the exercise
price at any time until (American  style) or on (European style) the  expiration
date.  An Underlying  Theme Portfolio may  enter into  closing sale transactions
with respect to  such options,  exercise such option  or permit  such option  to
expire.
 
Each  Underlying  Theme Portfolio  may purchase  a put  option on  an underlying
security or currency ("protective put") owned by the Underlying Theme  Portfolio
in  order to protect against an anticipated decline in the value of the security
or currency. Such hedge protection is provided  only during the life of the  put
option  when the Underlying Theme Portfolio, as the holder of the put option, is
able to  sell the  underlying security  or currency  at the  put exercise  price
regardless  of  any  decline  in  the  underlying  security's  market  price  or
currency's exchange  value.  The  premium  paid  for  the  put  option  and  any
transaction  costs would reduce any  profit otherwise available for distribution
when the security or currency is eventually sold.
 
An Underlying Theme Portfolio may  also purchase put options  at a time when  it
does not own the underlying security or currency. By purchasing put options on a
security  or currency it does not own,  that Underlying Theme Portfolio seeks to
benefit from  a  decline in  the  market price  of  the underlying  security  or
currency.  If the put option is not sold when it has remaining value, and if the
market price of the underlying security or currency remains equal to or  greater
than  the exercise price during the life of the put option, the Underlying Theme
Portfolio will lose its entire  investment in the put  option. In order for  the
purchase  of a put option  to be profitable, the  market price of the underlying
security or currency must decline sufficiently below the exercise price to cover
the premium and transaction costs,  unless the put option  is sold in a  closing
sale transaction.

PURCHASING CALL OPTIONS
Each Underlying Theme Portfolio may purchase call options on securities, indices
and  currencies. As the holder  of a call option,  an Underlying Theme Portfolio
would have the  right to  purchase the underlying  security or  currency at  the
exercise  price at any  time until (American  style) or on  (European style) the
expiration date.  An Underlying  Theme  Portfolio may  enter into  closing  sale
transactions  with respect to such options, exercise such options or permit such
options to expire.
 
Call options may be purchased by  an Underlying Theme Portfolio for the  purpose
of  acquiring the underlying security or currency for its portfolio. Utilized in
this fashion, the  purchase of  call options  would enable  an Underlying  Theme
Portfolio  to acquire the security or currency at the exercise price of the call
option plus the premium paid. At times,  the net cost of acquiring the  security
or  currency in this manner may be less  than the cost of acquiring the security
or currency directly. This technique may  also be useful to an Underlying  Theme
Portfolio in purchasing a large block of securities that would be more difficult
to  acquire by direct market purchases. So long  as it holds such a call option,
rather than the  underlying security  or currency itself,  the Underlying  Theme
Portfolio is partially protected from any unexpected decline in the market price
of  the underlying security or currency and, in such event, could allow the call
option to expire, incurring a  loss only to the extent  of the premium paid  for
the option.
 
An  Underlying  Theme Portfolio  may also  purchase  call options  on underlying
securities or currencies it owns to avoid realizing losses that would result  in
a  reduction  of its  current  return. For  example,  where an  Underlying Theme
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 Underlying  Theme Portfolio and the realization of  a
loss  on the underlying security or  currency. Accordingly, the Underlying Theme
Portfolio could  purchase a  call  option on  the  same underlying  security  or
currency, which could be exercised to fulfill its delivery obligations under its
written  call (if  it is  exercised). This  strategy could  allow the Underlying
Theme Portfolio to avoid  selling the portfolio security  or currency at a  time
when  it has an  unrealized loss; however, the  Underlying Theme Portfolio would
have to pay a premium to purchase the call option plus transaction costs.
 
Aggregate premiums paid  for put and  call options  will not exceed  5% of  each
Underlying Theme Portfolio's total assets at the time of each purchase.
 
An  Underlying Theme Portfolio  may attempt to  accomplish objectives similar to
those involved in using Forward Contracts  by purchasing put or call options  on
currencies.  A put option  gives an Underlying Theme  Portfolio as purchaser the
right (but not the  obligation) to sell  a specified amount  of currency at  the
exercise  price at any  time until (American  style) or on  (European style) the
expiration date of the option. A call option gives an Underlying Theme Portfolio
as purchaser the right (but not  the obligation) to purchase a specified  amount
of  currency at  the exercise  price at  any time  until (American  style) or on
(European style)  the  expiration  date  of  the  option.  An  Underlying  Theme
Portfolio  might purchase a currency put  option, for example, to protect itself
against a  decline in  the dollar  value  of a  currency in  which it  holds  or
anticipates  holding securities. If the  currency's value should decline against
the dollar, the loss in currency value should be offset, in whole or in part, by
an increase in the value of the put. If the value of the currency instead should
rise against the  dollar, any  gain to an  Underlying Theme  Portfolio would  be
reduced  by the premium it  had paid for the put  option. A currency call option
might be purchased, for  example, in anticipation of,  or to protect against,  a
rise  in the value against the dollar of a currency in which an Underlying Theme
Portfolio anticipates purchasing securities.
 
Options may  be either  listed  on an  exchange  or traded  in  over-the-counter
("OTC")  markets. Listed options are third-party contracts (I.E., performance of
the obligations of  the purchaser and  seller is guaranteed  by the exchange  or
clearing  corporation) and have standardized strike prices and expiration dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates. An Underlying Theme Portfolio will  not purchase an OTC option unless  it
believes  that daily  valuations for  such options  are readily  obtainable. OTC
options differ from exchange-traded options  in that OTC options are  transacted
with  dealers directly and not through  a clearing corporation (which guarantees
performance). Consequently, there is  a risk of  non-performance by the  dealer.
Since no exchange is involved, OTC options are valued on the basis of an average
of  the last bid prices obtained from  dealers, unless a quotation from only one
dealer is available, in which case only that dealer's price will be used. In the
case of OTC options, there  can be no assurance  that a liquid secondary  market
will exist for any particular option at any specific time.
 
The  staff of the Securities and Exchange Commission ("SEC") considers purchased
OTC options to be  illiquid securities. An Underlying  Theme Portfolio may  also
sell  OTC options  and, in connection  therewith, segregate assets  or cover its
obligations with respect to OTC options written by it. The assets used as  cover
for  OTC options  written by  an Underlying  Theme Portfolio  will be considered
illiquid unless the OTC options are sold to qualified dealers who agree that the
Underlying Theme Portfolio may repurchase any OTC option it writes at a  maximum
price to be calculated by a formula
 
                   Statement of Additional Information Page 9
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
An Underlying Theme Portfolio's ability to establish and close out positions  in
exchange-listed  options  depends  on the  existence  of a  liquid  market. Each
Underlying  Theme   Portfolio  intends   to  purchase   or  write   only   those
exchange-traded options for which there appears to be a liquid secondary market.
However,  there  can  be no  assurance  that such  a  market will  exist  at any
particular time.  Closing transactions  can  be made  for  OTC options  only  by
negotiating  directly with the contra party or by a transaction in the secondary
market if any such  market exists. Although an  Underlying Theme Portfolio  will
enter  into OTC options only with contra parties that are expected to be capable
of entering into closing  transactions with it, there  is no assurance that  the
Underlying  Theme Portfolio  will in  fact be  able to  close out  an OTC option
position at a favorable price prior to expiration. In the event of insolvency of
the contra party, the Underlying Theme Portfolio might be unable to close out an
OTC option position at any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts except that all settlements  are in cash and  gain or loss depends  on
changes  in the index in question (and thus on price movements in the securities
market or a particular market sector  generally) rather than on price  movements
in  individual  securities  or  futures  contracts.  When  an  Underlying  Theme
Portfolio writes a  call on an  index, it  receives a premium  and agrees  that,
prior  to the expiration date,  the purchaser of the  call, upon exercise of the
call, will receive from the Underlying Theme 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 an Underlying  Theme Portfolio buys  a
call  on an index, it pays a premium and  has the same rights as to such call as
are indicated above. When an Underlying Theme Portfolio buys a put on an  index,
it  pays a premium and  has the right, prior to  the expiration date, to require
the seller of  the put, upon  the Underlying Theme  Portfolio's exercise of  the
put,  to deliver  to the  Underlying Theme  Portfolio an  amount of  cash if the
closing level of the index upon which the put is based is less than the exercise
price of the  put, which  amount of  cash is  determined by  the multiplier,  as
described  above for calls. When the Underlying  Theme Portfolio writes a put on
an index, it receives a  premium and the purchaser has  the right, prior to  the
expiration  date, to require the Underlying Theme  Portfolio to deliver to it an
amount of cash equal to  the difference between the  closing level of the  index
and  the exercise price times the multiplier,  if the closing level is less than
the exercise price.
 
The risks  of  investment  in index  options  may  be greater  than  options  on
securities.  Because index options are settled in cash, when an Underlying Theme
Portfolio writes  a call  on  an index  it cannot  provide  in advance  for  its
potential  settlement  obligations  by  acquiring  and  holding  the  underlying
securities. An Underlying Theme Portfolio can offset some of the risk of writing
a call index option  position by holding a  diversified portfolio of  securities
similar  to those on which the underlying index is based. However, an Underlying
Theme Portfolio cannot,  as a  practical matter,  acquire and  hold a  portfolio
containing  exactly the same securities as underlie  the index and, as a result,
bears a risk that the value of the  securities held will vary from the value  of
the index.
 
Even if an Underlying Theme Portfolio could assemble a securities portfolio that
exactly  reproduced the composition of the  underlying index, it still would not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing index options.  When an index  option is exercised,  the amount of  cash
that  the holder is entitled to receive  is determined by the difference between
the exercise price and the  closing index level on the  date when the option  is
exercised.  As with other  kinds of options, the  Underlying Theme Portfolio, as
the call writer, will not know that it has been assigned until the next business
day at the  earliest. The  time lag between  exercise and  notice of  assignment
poses  no  risk  for the  writer  of a  covered  call on  a  specific underlying
security, such as  common stock,  because there  the writer's  obligation is  to
deliver  the underlying security, not to pay its value as of a fixed time in the
past. So long as the writer already owns the underlying security, it can satisfy
its settlement obligations by simply delivering it, and the risk that its  value
may  have declined since the exercise date is borne by the exercising holder. In
contrast, even if  the writer  of an index  call holds  securities that  exactly
match  the composition of the  underlying index, it will  not be able to satisfy
its assignment obligations by delivering those securities against payment of the
exercise price. Instead, it will be required  to pay cash in an amount based  on
the  closing index value on the exercise date; and by the time it learns that it
has been assigned, the index may have declined, with a corresponding decline  in
the  value  of  its securities  portfolio.  This  "timing risk"  is  an inherent
limitation on the ability of index call writers to cover their risk exposure  by
holding securities positions.
 
If  an Underlying  Theme Portfolio  purchases an  index option  and exercises it
before the closing index value for that day is available, it runs the risk  that
the  level of  the underlying  index may subsequently  change. If  such a change
causes the

exercised option to fall out-of-the-money,  the Underlying Theme Portfolio  will
be  required  to pay  the difference  between  the closing  index value  and the
exercise price of the option (times  the applicable multiplier) to the  assigned
writer.
 
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
Each  Underlying Theme Portfolio may enter into interest rate, currency or stock
index futures contracts  (collectively, "Futures" or  "Futures Contracts") as  a
hedge  against changes in prevailing levels of interest rates, currency exchange
rates or stock price levels, respectively, in order to establish more definitely
the effective return on securities or currencies held or intended to be acquired
by it. An Underlying Theme Portfolio's  hedging may include sales of Futures  as
an  offset  against the  effect  of expected  increases  in interest  rates, and
decreases in currency exchange rates and stock prices, and purchases of  Futures
as  an offset  against the  effect of expected  declines in  interest rates, and
increases in currency exchange rates or stock prices.
 
Each Underlying Theme Portfolio only will enter into Futures Contracts that  are
traded  on  futures  exchanges and  are  standardized  as to  maturity  date and
underlying financial instrument.  Futures exchanges and  trading thereon in  the
United  States are regulated  under the Commodity Exchange  Act by the Commodity
Futures Trading  Commission ("CFTC").  Futures are  exchanged in  London at  the
London International Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used  to  reduce  an Underlying  Theme  Portfolio's exposure  to  interest rate,
currency exchange  rate  and  stock market  fluctuations,  an  Underlying  Theme
Portfolio may be able to hedge its exposure more effectively and at a lower cost
through using Futures Contracts.
 
A  Futures Contract provides  for the future  sale by one  party and purchase by
another party of a specified amount of a specific financial instrument (security
or currency) for a specified price at a designated date, time and place. A stock
index Futures Contract provides for the delivery, at a designated date, time and
place, of  an amount  of  cash equal  to a  specified  dollar amount  times  the
difference between the stock index value at the close of trading on the contract
and  the price at which  the Futures Contract is  originally struck; no physical
delivery of stocks  comprising the index  is made. Brokerage  fees are  incurred
when  a  Futures  Contract  is  bought or  sold,  and  margin  deposits  must be
maintained at all times the Futures Contract is outstanding.
 
Although Futures Contracts typically require future delivery of and payment  for
financial  instruments or currencies,  Futures Contracts usually  are closed out
before the delivery date. Closing out an open Futures Contract sale or  purchase
is  effected by entering  into an offsetting Futures  Contract purchase or sale,
respectively,  for  the  same  aggregate  amount  of  the  identical   financial
instrument  or currency and  the same delivery date.  If the offsetting purchase
price is  less than  the original  sale price,  the Underlying  Theme  Portfolio
realizes  a gain; if it is more, the Underlying Theme Portfolio realizes a loss.
Conversely, if the  offsetting sale  price is  more than  the original  purchase
price,  the  Underlying Theme  Portfolio realizes  a  gain; if  it is  less, the
Underlying Theme Portfolio realizes a loss.  The transaction costs must also  be
included  in these  calculations. There  can be  no assurance,  however, that an
Underlying Theme Portfolio will be able to enter into an offsetting  transaction
with  respect  to a  particular Futures  Contract  at a  particular time.  If an
Underlying Theme Portfolio is not able to enter into an offsetting  transaction,
it  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 Underlying
Theme Portfolio.
 
Each  Underlying Theme Portfolio's Futures transactions will be entered into for
hedging purposes  only; that  is,  Futures Contracts  will  be sold  to  protect
against  a decline in the  price of securities or  currencies that an Underlying
Theme Portfolio  owns, or  Futures Contracts  will be  purchased to  protect  an
Underlying  Theme Portfolio  against an increase  in the price  of securities or
currencies it has committed to purchase or expects to purchase.
 
"Margin" with respect to Futures Contracts is  the amount of funds that must  be
deposited  by an Underlying Theme Portfolio in order to initiate Futures trading
and maintain its open positions in Futures Contracts. A margin deposit made when
the Futures Contract is  entered into ("initial margin")  is intended to  ensure
the  Underlying Theme  Portfolio's performance  under the  Futures Contract. The
margin required for  a particular  Futures Contract is  set by  the exchange  on
which the Futures Contract is traded and may be significantly modified from time
to time by the exchange during the term of the Futures Contract.
 
                  Statement of Additional Information Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission merchant through  which the Underlying  Theme Portfolio entered  into
the  Futures  Contract  will be  made  on a  daily  basis  as the  price  of the
underlying security, currency  or index fluctuates  making the Futures  Contract
more or less valuable, a process known as marking-to-market.
 
    RISKS  OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts are
volatile and  are influenced  by,  among other  things, actual  and  anticipated
changes  in  interest rates  and currency  exchange rates,  and in  stock market
movements, which  in turn  are  affected by  fiscal  and monetary  policies  and
national and international political and economic events.
 
There  is a risk of  imperfect correlation between changes  in prices of Futures
Contracts and prices  of the  securities or  currencies in  an Underlying  Theme
Portfolio's  portfolio being hedged.  The degree of  imperfection of correlation
depends upon circumstances such as  variations in speculative market demand  for
Futures  and  for securities  or currencies,  including technical  influences in
Futures trading; and differences between the financial instruments being  hedged
and  the  instruments underlying  the standard  Futures Contracts  available for
trading. A  decision  of whether,  when  and how  to  hedge involves  skill  and
judgment,  and even  a well-conceived hedge  may be unsuccessful  to some degree
because of unexpected market behavior or interest or currency rate trends.
 
Because of  the  low  margin  deposits required,  Futures  trading  involves  an
extremely  high  degree  of leverage.  As  a  result, a  relatively  small price
movement in a Futures Contract may result in immediate and substantial loss,  as
well  as gain, to the investor. For example,  if at the time of purchase, 10% of
the value  of the  Futures Contract  is deposited  as margin,  a subsequent  10%
decrease  in the value of  the Futures Contract would result  in a total loss of
the margin  deposit, before  any deduction  for the  transaction costs,  if  the
account  were then closed  out. A 15% decrease  would result in  a loss equal to
150% of the original  margin deposit, if the  Futures Contract were closed  out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract  and options on  Futures Contracts prices during  a single trading day.
The daily  limit establishes  the maximum  amount that  the price  of a  Futures
Contract or option may vary either up or down from the previous day's settlement
price  at the end of a trading session. Once the daily limit has been reached in
a particular type of Futures Contract or  option, no trades may be made on  that
day  at a price beyond  that limit. The daily  limit governs only price movement
during a particular trading day and  therefore does not limit potential  losses,
because  the limit may prevent the liquidation of unfavorable positions. Futures
Contracts and  option prices  have occasionally  moved to  the daily  limit  for
several  consecutive trading days with little  or no trading, thereby preventing
prompt liquidation  of  positions and  subjecting  some traders  to  substantial
losses.
 
If an Underlying Theme Portfolio were unable to liquidate a Futures or option on
Futures  position  due  to the  absence  of  a liquid  secondary  market  or the
imposition of price limits,  it could incur  substantial losses. The  Underlying
Theme  Portfolio would continue to be subject to market risk with respect to the
position. In addition, except in the  case of purchased options, the  Underlying
Theme  Portfolio would  continue to be  required to make  daily variation margin
payments and might  be required  to maintain the  position being  hedged by  the
Future or option or to maintain cash or securities in a segregated account.
 
Certain  characteristics  of the  Futures market  might  increase the  risk that
movements in the  prices of Futures  Contracts or options  on Futures might  not
correlate  perfectly  with  movements in  the  prices of  the  investments being
hedged. For example,  all participants  in the  Futures and  options on  Futures
markets  are subject to daily  variation margin calls and  might be compelled to
liquidate Futures  or  options on  Futures  positions whose  prices  are  moving
unfavorably  to avoid being  subject to further  calls. These liquidations could
increase price  volatility  of the  instruments  and distort  the  normal  price
relationship  between the Futures  or options and  the investments being hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous than  margin requirements  in  the securities  markets, there  might  be
increased   participation   by  speculators   in   the  Futures   markets.  This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage,  "program trading"  and other  investment strategies  might result in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options on Futures Contracts are similar to options on securities or  currencies
except that options on Futures Contracts give the purchaser the right, in return
for  the  premium paid,  to  assume a  position in  a  Futures Contract  (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price  at any time  during the period  of the option.  Upon
exercise  of the option, the  delivery of the Futures  position by the writer of
the option to the holder  of the option will be  accompanied by delivery of  the
accumulated balance in the writer's Futures margin account, which represents the
amount  by which the market price of  the Futures Contract, at exercise, exceeds
(in the case of a call) or is less
 
                  Statement of Additional Information Page 12
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 an Underlying Theme Portfolio writes an option on a Futures Contract, it will
be  required to  deposit initial and  variation margin  pursuant to requirements
similar to those  applicable to  Futures Contracts. Premiums  received from  the
writing  of an option on  a Futures Contract are  included in the initial margin
deposit.
 
An Underlying  Theme Portfolio  may seek  to  close out  an option  position  by
selling  an  option  covering the  same  Futures  Contract and  having  the same
exercise price  and expiration  date. The  ability to  establish and  close  out
positions  on such options is  subject to the maintenance  of a liquid secondary
market.
 
LIMITATIONS ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS  ON
CURRENCIES
To  the extent that an Underlying Theme Portfolio enters into Futures Contracts,
options on  Futures Contracts  and options  on foreign  currencies traded  on  a
CFTC-regulated  exchange, in each case other than for bona fide hedging purposes
(as defined by the CFTC), the aggregate initial margin and premiums required  to
establish   those  positions  (excluding   the  amount  by   which  options  are
"in-the-money") will not exceed  5% of the liquidation  value of the  Underlying
Theme  Portfolio, after  taking into  account unrealized  profits and unrealized
losses on any  contracts it has  entered into. In  general, a call  option on  a
Futures  Contract  is  "in-the-money" if  the  value of  the  underlying Futures
Contract exceeds the strike, I.E., exercise, price of the call; a put option  on
a  Futures Contract  is "in-the-money"  if the  value of  the underlying Futures
Contract is exceeded  by the  strike price  of the  put. This  guideline may  be
modified  by the applicable  Board, without a  shareholder vote. This limitation
does not limit the percentage of an Underlying Theme Portfolio's assets at  risk
to 5%.
 
FORWARD CONTRACTS
A  Forward Contract is an obligation, usually arranged with a commercial bank or
other currency dealer, to purchase or  sell a currency against another  currency
at  a future date and  price as agreed upon by  the parties. An Underlying Theme
Portfolio either may accept or make delivery of the currency at the maturity  of
the  Forward Contract.  An Underlying  Theme Portfolio  may also,  if its contra
party agrees prior to maturity, enter  into a closing transaction involving  the
purchase or sale of an offsetting contract.
 
An  Underlying  Theme  Portfolio  engages in  forward  currency  transactions in
anticipation of, or to protect  itself against, fluctuations in exchange  rates.
An  Underlying Theme Portfolio might sell a particular foreign currency forward,
for example,  when  it  holds  bonds  denominated  in  a  foreign  currency  but
anticipates,  and  seeks to  be  protected against,  a  decline in  the currency
against the U.S. dollar. Similarly, an Underlying Theme Portfolio might sell the
U.S. dollar  forward  when  it  holds bonds  denominated  in  U.S.  dollars  but
anticipates,  and seeks to  be protected against,  a decline in  the U.S. dollar
relative to  other  currencies. Further,  an  Underlying Theme  Portfolio  might
purchase  a currency forward to "lock in" the price of securities denominated in
that currency that it anticipates purchasing.
 
Forward Contracts are traded in the interbank market conducted directly  between
currency traders (usually large commercial banks) and their customers. A Forward
Contract generally has no deposit requirement, and no commissions are charged at
any  stage  for trades.  Each Underlying  Theme Portfolio  will enter  into such
Forward Contracts with major  U.S. or foreign banks  and securities or  currency
dealers in accordance with guidelines approved by the applicable Board.
 
An  Underlying  Theme Portfolio  may enter  into  Forward Contracts  either with
respect to specific transactions or with respect to overall investments of  that
Underlying Theme Portfolio. The precise matching of the Forward Contract amounts
and  the value of specific securities generally will not be possible because the
future value  of  such  securities  in  foreign  currencies  will  change  as  a
consequence  of market  movements in the  value of those  securities between the
date the Forward Contract is entered into and the date it matures.  Accordingly,
it  may be necessary for that  Underlying Theme Portfolio to purchase additional
foreign currency on the spot (I.E., cash)  market (and bear the expense of  such
purchase) if the market value of the security is less than the amount of foreign
currency  the  Underlying  Theme Portfolio  is  obligated  to deliver  and  if a
decision is made to sell the security and make delivery of the foreign currency.
Conversely, it may be necessary to sell  on the spot market some of the  foreign
currency  the Underlying Theme Portfolio is obligated to deliver. The projection
of  short-term  currency  market  movements  is  extremely  difficult,  and  the
successful execution of a short-
 
                  Statement of Additional Information Page 13
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
term  hedging strategy is  highly uncertain. Forward  Contracts involve the risk
that anticipated currency movements will not be predicted accurately, causing an
Underlying Theme Portfolio to sustain losses on these contracts and  transaction
costs.
 
At  or before the maturity  of a Forward Contract  requiring an Underlying Theme
Portfolio to sell a  currency, it either  may sell a security  and use the  sale
proceeds  to make delivery of the currency or retain the security and offset its
contractual obligation to deliver the  currency by purchasing a second  contract
pursuant  to which it will obtain, on the same maturity date, the same amount of
the currency that  it is obligated  to deliver. Similarly,  an Underlying  Theme
Portfolio  may close out a Forward Contract requiring it to purchase a specified
currency by  entering  into a  second  contract,  if its  contra  party  agrees,
entitling  it to sell the same amount of  the same currency on the maturity date
of the first  contract. An Underlying  Theme Portfolio would  realize a gain  or
loss  as a  result of  entering into such  an offsetting  Forward Contract under
either circumstance  to  the extent  the  exchange  rate or  rates  between  the
currencies  involved moved between the execution dates of the first contract and
the offsetting contract.
 
The cost  to an  Underlying Theme  Portfolio of  engaging in  Forward  Contracts
varies  with factors such as the currencies involved, the length of the contract
period and the market conditions then prevailing. Because Forward Contracts  are
usually  entered into on a principal basis, no fees or commissions are involved.
The use of Forward  Contracts does not eliminate  fluctuations in the prices  of
the  underlying  securities an  Underlying Theme  Portfolio  owns or  intends to
acquire, but it does establish a rate of exchange in advance. In addition, while
Forward Contract sales limit the risk of loss  due to a decline in the value  of
the  hedged currencies,  they also  limit any  potential gain  that might result
should the value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
An Underlying Theme Portfolio may use options on foreign currencies, Futures  on
foreign  currencies,  options  on  Futures  on  foreign  currencies  and Forward
Contracts to hedge against movements in the values of the foreign currencies  in
which the Underlying Theme Portfolio's securities are denominated. Such currency
hedges  can protect  against price movements  in a security  that the Underlying
Theme Portfolio owns or intends to  acquire that are attributable to changes  in
the  value  of the  currency in  which it  is denominated.  Such hedges  do not,
however, protect against price movements in the securities that are attributable
to other causes.
 
An Underlying Theme Portfolio might seek  to hedge against changes in the  value
of  a particular currency  when no Futures Contract,  Forward Contract or option
involving that currency is available or one of such contracts is more  expensive
than  certain other contracts. In such cases, the Underlying Theme Portfolio may
hedge against price movements  in that currency by  entering into a contract  on
another  currency  or basket  of  currencies, the  values  of which  the Manager
believes will have  a positive correlation  to the value  of the currency  being
hedged.  The risk that movements in the price of the contract will not correlate
perfectly with movements in the price of the currency being hedged is  magnified
when this strategy is used.
 
The  value of Futures Contracts, options on Futures Contracts, Forward Contracts
and options  on  foreign currencies  depends  on  the value  of  the  underlying
currency  relative  to the  U.S. dollar.  Because foreign  currency transactions
occurring in the  interbank market  might involve  substantially larger  amounts
than  those  involved in  the  use of  Futures  Contracts, Forward  Contracts or
options, the Underlying Theme Portfolio could be disadvantaged by dealing in the
odd lot market (generally  consisting of transactions of  less than $1  million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
There is no systematic reporting of last sale information for foreign currencies
or  any  regulatory requirements  that quotations  available through  dealers or
other market sources be firm or revised on a timely basis. Quotation information
generally is representative of very  large transactions in the interbank  market
and  thus  might not  reflect  odd-lot transactions  where  rates might  be less
favorable.  The   interbank  market   in  foreign   currencies  is   a   global,
round-the-clock  market. To the  extent the U.S. options  or Futures markets are
closed while the markets for the underlying currencies remain open,  significant
price  and rate movements might take place in the underlying markets that cannot
be reflected in  the markets  for the Futures  contracts or  options until  they
reopen.
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies  might  be required  to  take place  within  the country  issuing the
underlying currency. Thus, an  Underlying Theme Portfolio  might be required  to
accept  or make delivery  of the underlying foreign  currency in accordance with
any U.S. or  foreign regulations  regarding the maintenance  of foreign  banking
arrangements  by U.S. residents and might be required to pay any fees, taxes and
charges associated with such delivery assessed in the issuing country.

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

                              RISK FACTORS OF THE
                          UNDERLYING THEME PORTFOLIOS
 
- --------------------------------------------------------------------------------
 
DEBT SECURITIES
The  value  of  the debt  securities  held  by each  Underlying  Theme Portfolio
generally will vary conversely with market interest rates. If interest rates  in
a  market fall, the value  of the debt securities  held by each Underlying Theme
Portfolio ordinarily will rise. If market interest rates increase, however,  the
debt  securities owned by each Underlying Theme Portfolio in that market will be
likely to decrease in value.
 
The Global  Consumer  Products  and Services  Portfolio,  Global  Infrastructure
Portfolio  and Global Natural Resources  Portfolio may each invest  up to 20% of
its  total  assets  in  debt  securities  rated  below  investment  grade.  Such
investments  involve a high  degree of risk. However,  those Portfolios will not
invest in debt securities  that are in  default as to  payment of principal  and
interest.
 
Debt  rated Baa  by Moody's Investors  Service, Inc. ("Moody")  is considered by
Moody's to have speculative characteristics. Debt rated  BB, B, CCC, CC or C  by
Standard  & Poor's, a  division of The McGraw-Hill  Companies, Inc. ("S&P"), and
debt rated  Ba,  B,  Caa, Ca  or  C  by  Moody's is  regarded,  on  balance,  as
predominantly  speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. For S&P,  BB
indicates the lowest degree of speculation for such lower quality debt and C the
highest  degree of speculation. For Moody's,  Baa indicates the lowest degree of
speculation for such lower quality debt and C the highest degree of speculation.
While such  lower quality  debt will  likely have  some quality  and  protective
characteristics,  these  are outweighed  by  large uncertainties  or  major risk
exposures to adverse conditions. Debt  rated C by Moody's  or S&P is the  lowest
rated  debt that is  not in default as  to principal or  interest, and issues so
rated can be regarded as having  extremely poor prospects of ever attaining  any
real  investment  standing. Lower  quality  debt securities  also  are generally
considered to be  subject to greater  risk than securities  with higher  ratings
with  regard  to a  deterioration of  general  economic conditions.  These lower
quality debt  securities are  the equivalent  of high  yield, high  risk  bonds,
commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality  and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments  and do not evaluate the risks  of
fluctuations  in market  value. Also,  rating agencies  may fail  to make timely
changes in credit ratings in response to subsequent events, so that an  issuer's
current financial condition may be better or worse than a rating indicates.
 
The  market values of  lower quality debt securities  tend to reflect individual
developments  of  the  issuer  to  a  greater  extent  than  do  higher  quality
securities,  which  react  primarily to  fluctuations  in the  general  level of
interest rates.  In addition,  lower quality  debt securities  tend to  be  more
sensitive  to economic conditions  and generally have  more volatile prices than
higher quality securities. Issuers of lower quality securities are often  highly
leveraged  and  may  not have  available  to  them more  traditional  methods of
financing. For example,  during an economic  downturn or a  sustained period  of
rising  interest rates, highly leveraged issuers of lower quality securities may
experience financial  stress. During  such periods,  such issuers  may not  have
sufficient  revenues to  meet their  interest payment  obligations. The issuer's
ability to  service its  debt  obligations may  also  be adversely  affected  by
specific  developments affecting the  issuer, such as  the issuer's inability to
 
                  Statement of Additional Information Page 15

                          GT GLOBAL NEW DIMENSION FUND
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 that permit the issuer to call or repurchase the security from
an  Underlying Theme  Portfolio. If  an issuer  exercises these  provisions in a
declining interest  rate market,  the  Underlying Theme  Portfolio may  have  to
replace  the security with  a lower yielding security,  resulting in a decreased
return for  investors. In  addition, the  Underlying Theme  Portfolios may  have
difficulty  disposing of lower  quality securities because they  may have a thin
trading market. There may be no established retail secondary market for many  of
these  securities,  and each  Underlying Theme  Portfolio anticipates  that such
securities could be sold  only to a limited  number of dealers or  institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on  market prices  of such instruments  and may  make it more  difficult for the
Underlying Theme Portfolios to obtain accurate market quotations for purposes of
valuing their portfolio  investments. The Underlying  Theme Portfolios may  also
acquire  lower quality debt  securities during an  initial underwriting or which
are sold without registration under applicable securities laws. Such  securities
involve special considerations and risks.
 
In  addition to the foregoing, factors that  could have an adverse effect on the
market value of  lower quality  debt securities  in which  the Underlying  Theme
Portfolios  may invest include: (i) potential adverse publicity; (ii) heightened
sensitivity to general economic  or political conditions;  and (iii) the  likely
adverse  impact of a major economic recession. An Underlying Theme Portfolio may
also incur additional  expenses to the  extent it is  required to seek  recovery
upon  a default in the  payment of principal or  interest on portfolio holdings,
and the Underlying Theme Portfolio may have limited legal recourse in the  event
of a default.
 
The   Manager  attempts  to  minimize  the  speculative  risks  associated  with
investments in lower quality securities through credit analysis and by carefully
monitoring current trends  in interest rates,  political developments and  other
factors.
 
ILLIQUID SECURITIES
Each  Underlying Theme Portfolio may invest up  to 15% of its net assets (except
for the Health Care  Fund, which may invest  up to 10% of  its total assets)  in
illiquid  securities.  Securities may  be considered  illiquid if  an Underlying
Theme  Portfolio  cannot  reasonably  expect  within  seven  days  to  sell  the
securities  for approximately the amount at which it values such securities. See
"Investment Limitations of the Underlying Theme Funds and Portfolios." The  sale
of  illiquid securities, if they can be sold at all, generally will require more
time and  result in  higher  brokerage charges  or  dealer discounts  and  other
selling  expenses than  will the  sale of  liquid securities  such as securities
eligible for trading on U.S. securities  exchanges or in OTC markets.  Moreover,
restricted  securities, which may  be illiquid for  purposes of this limitation,
often sell, if at  all, at a  price lower than similar  securities that are  not
subject to restrictions on resale.
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, an Underlying Theme Portfolio may be obligated to pay
all or part of  the registration expenses and  a considerable period may  elapse
between  the time  of the  decision to  sell and  the time  the Underlying Theme
Portfolio may be permitted  to sell a security  under an effective  registration
statement.  If, during such a period, adverse market conditions were to develop,
the Underlying  Theme  Portfolio  might  obtain  a  less  favorable  price  than
prevailed when it decided to sell.
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under  the Securities  Act  of 1933,  as  amended (the  "1933 Act"),
including private placements, repurchase  agreements, commercial paper,  foreign
securities and corporate bonds and notes. These instruments are often restricted
securities  because  the  securities  are  sold  in  transactions  not requiring
registration. Institutional  investors generally  will not  seek to  sell  these
instruments  to the general public,  but instead will often  depend either on an
efficient institutional  market in  which such  unregistered securities  can  be
readily  resold  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-
 
                  Statement of Additional Information Page 16
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
eligible restricted securities held by  an Underlying Theme Portfolio,  however,
could  affect adversely the marketability of  such portfolio securities, and the
Underlying Theme  Portfolio  might  be  unable to  dispose  of  such  securities
promptly or at favorable prices.
 
With respect to liquidity determinations generally, the applicable Board has the
ultimate  responsibility for determining  whether specific securities, including
restricted securities pursuant to  Rule 144A under the  1933 Act, are liquid  or
illiquid.   Each  Board  has   delegated  the  function   of  making  day-to-day
determinations of  liquidity  to  the Manager,  in  accordance  with  procedures
approved  by that 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 monitors  the
liquidity of securities held by each Underlying Theme Portfolio and periodically
reports  such determinations to the applicable  Board. The Manager believes that
carefully selected investments in joint ventures, cooperatives, partnerships and
state enterprises that are  illiquid (collectively, "Special Situations")  could
enable   an  Underlying   Theme  Portfolio   to  achieve   capital  appreciation
substantially exceeding the  appreciation it would  realize if it  did not  make
such  investments. However, in  order to attempt to  limit investment risk, each
Underlying Theme Portfolio will invest  no more than 5%  of its total assets  in
Special Situations.
 
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, an Underlying Theme Portfolio could lose its entire
investment in any such country.
 
    RELIGIOUS,  POLITICAL AND ETHNIC INSTABILITY.  Certain countries in which an
Underlying Theme  Portfolio may  invest may  have groups  that advocate  radical
religious  or  revolutionary philosophies  or  support ethnic  independence. Any
disturbance on  the part  of  such individuals  could  carry the  potential  for
widespread  destruction  or confiscation  of property  owned by  individuals and
entities foreign to such country and could cause the loss of an Underlying Theme
Portfolio's investment in  those countries.  Instability may  also result  from,
among  other things,  (i) authoritarian  governments or  military involvement in
political and economic decision-making, including changes in government  through
extra-constitutional  means,  (ii) popular  unrest  associated with  demands for
improved political, economic and social conditions; and (iii) hostile  relations
with  neighboring  or  other  countries.  Such  political,  social  and economic
instability could disrupt the principal financial markets in which an Underlying
Theme Portfolio invests and adversely affect the value of its 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 an Underlying Theme Portfolio.
These restrictions or  controls may at  times limit or  preclude investments  in
certain securities and may increase the cost and expenses of an Underlying Theme
Portfolio.  For example,  certain countries require  prior governmental approval
before investments by foreign  persons may be  made or may  limit the amount  of
investment by foreign persons in a particular company or limit the investment by
foreign  persons to only  a specific class  of securities of  a company that may
have less  advantageous  terms than  securities  of the  company  available  for
purchase  by nationals. Moreover, the national policies of certain countries may
restrict investment opportunities in issuers  or industries deemed sensitive  to
national  interests. In  addition, some countries  require governmental approval
for the repatriation of investment income, capital or the proceeds of securities
sales by  foreign investors.  In addition,  if  there is  a deterioration  in  a
country's  balance  of  payments or  for  other  reasons, a  country  may impose
restrictions  on  foreign  capital  remittances  abroad.  An  Underlying   Theme
Portfolio  could be adversely affected by delays  in, or a refusal to grant, any
required governmental approval for repatriation,  as well as by the  application
to it of other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting  principles.  Most of  the  foreign securities  held  by  an
Underlying  Theme Portfolio will not be registered with the SEC or regulators of
any foreign  country, nor  will the  issuers  thereof be  subject to  the  SEC's
reporting   requirements.  Thus,  there  will   be  less  available  information
concerning most  foreign  issuers of  securities  held by  an  Underlying  Theme
Portfolio  than is  available concerning  U.S. issuers.  In instances  where the
financial statements  of an  issuer are  not deemed  to reflect  accurately  the
financial situation of the issuer, the
 
                  Statement of Additional Information Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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. In addition, where
public information is available, it may  be less reliable than such  information
regarding  U.S.  issuers. Issuers  of  securities in  foreign  jurisdictions are
generally not subject to the same degree of regulation as are U.S. issuers  with
respect  to such matters as restrictions on market manipulation, insider trading
rules, shareholder proxy requirements and timely disclosure of information.
 
    CURRENCY FLUCTUATIONS. Because each Underlying Theme Portfolio, under normal
circumstances, will invest  a substantial  portion of  its total  assets in  the
securities  of foreign issuers  that are denominated  in foreign currencies, the
strength or weakness  of the U.S.  dollar against such  foreign currencies  will
account  for part of  an Underlying Theme  Portfolio's investment performance. A
decline in the  value of any  particular currency against  the U.S. dollar  will
cause  a decline  in the  U.S. dollar value  of an  Underlying Theme Portfolio's
holdings of securities  and cash  denominated in that  currency and,  therefore,
will  cause an overall  decline in its  and its corresponding  Feeder Fund's net
asset value (as  applicable) and  any net  investment income  and capital  gains
derived  from  such  securities  to  be  distributed  in  U.S.  dollars  to  the
shareholders thereof. Moreover, if the value of the foreign currencies in  which
an  Underlying Theme  Portfolio receives its  income falls relative  to the U.S.
dollar between  receipt of  the  income and  the  making of  distributions,  the
Underlying  Theme Portfolio  may be required  to liquidate securities  if it 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  each Underlying  Theme Portfolio values  its assets daily  in terms of
U.S. dollars, the  Underlying Theme Portfolios  do not intend  to convert  their
holdings  of  foreign  currencies  into  U.S. dollars  on  a  daily  basis. Each
Underlying Theme Portfolio will do so,  from time to time, and investors  should
be  aware of the costs of currency conversion. Although foreign exchange dealers
do not  charge a  fee for  conversion, they  do realize  a profit  based on  the
difference  ("spread") between  the prices  at which  they buy  and sell various
currencies. Thus, a dealer may offer to sell a foreign currency to an Underlying
Theme Portfolio at one rate, while offering a lesser rate of exchange should  an
Underlying Theme Portfolio desire to sell that currency to the dealer.
 
    ADVERSE  MARKET CHARACTERISTICS. Securities  of many foreign  issuers may be
less liquid and their  prices more volatile than  securities of comparable  U.S.
issuers.  In  addition, foreign  securities  markets and  brokers  generally are
subject to  less governmental  supervision  and regulation  than in  the  United
States,  and  foreign  securities  transactions  usually  are  subject  to fixed
commissions, which  generally are  higher than  negotiated commissions  on  U.S.
transactions.  In addition,  foreign securities  transactions may  be subject to
difficulties associated  with the  settlement of  such transactions.  Delays  in
settlement  could result in temporary periods when assets of an Underlying Theme
Portfolio are uninvested and  no return is earned  thereon. The inability of  an
Underlying Theme Portfolio to make intended security purchases due to settlement
problems  could cause it to  miss attractive investment opportunities. Inability
to dispose  of a  portfolio security  due to  settlement problems  either  could
result  in losses to an Underlying Theme Portfolio due to subsequent declines in
value of  the portfolio  security or,  if that  Underlying Theme  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 an Underlying  Theme Portfolio's assets, although the  Manager
does  not believe that such difficulties will  have a material adverse effect on
an Underlying Theme Portfolio's portfolio trading activities.
 
Each Underlying Theme Portfolio  may use foreign  custodians, which may  involve
risks  in addition to  those related to  its use of  U.S. custodians. Such risks
include uncertainties relating  to (1)  determining and  monitoring the  foreign
custodian's   financial  strength,  reputation  and  standing,  (2)  maintaining
appropriate safeguards concerning an  Underlying Theme Portfolio's  investments,
and  (3) possible difficulties in obtaining and enforcing judgments against such
custodians.
 
    WITHHOLDING TAXES. Each Underlying  Theme Portfolio's net investment  income
from  securities of foreign issuers  may be subject to  withholding taxes by the
foreign issuer's country, thereby reducing  that income or delaying the  receipt
of income when those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION.  To  the  extent  an  Underlying  Theme  Portfolio  invests a
significant portion  of  its  assets  in securities  of  issuers  located  in  a
particular  country or region of  the world, it may  be subject to greater risks
and may  experience  greater  volatility  than  a  fund  that  is  more  broadly
diversified geographically.

    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Belgium,
Denmark,  France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg, Netherlands,
Portugal, Spain, and the United  Kingdom) eliminated certain import tariffs  and
quotas  and  other trade  barriers with  respect  to one  another over  the past
several years. The Manager  believes that this  deregulation should improve  the
prospects  for economic growth  in many Western  European countries. Among other
things, the  deregulation could  enable companies  domiciled in  one country  to
avail  themselves of lower labor costs existing in other countries. In addition,
this deregulation could benefit  companies domiciled in  one country by  opening
additional  markets  for their  goods and  services  in other  countries. Since,
however, it is not clear  what the exact form or  effect of these Common  Market
reforms  will be on business in Western  Europe, it is impossible to predict the
long-term impact of the implementation of these programs on the securities owned
by an Underlying Theme Portfolio.
 
    SPECIAL   CONSIDERATIONS    AFFECTING    RUSSIA   AND    EASTERN    EUROPEAN
COUNTRIES.  Investing in Russia  and Eastern European  countries involves a high
degree  of  risk  and  special  considerations  not  typically  associated  with
investing  in  the  U.S.  securities markets  and  should  be  considered highly
speculative. Such risks include the following: (1) delays in settling  portfolio
transactions  and risk of loss  arising out of the  system of share registration
and custody; (2) the risk  that it may be impossible  or more difficult than  in
other  countries  to  obtain and/or  enforce  a judgment;  (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  United States. In  general, however, reported  net income  in
Japan  is  understated relative  to U.S.  accounting standards  and this  is one
reason why price-earnings ratios of the stocks of Japanese companies have tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally been  lower than in  the United  States,
both   factors  which  tend  to  result  in  lower  discount  rates  and  higher
price-earnings ratios in Japan than in the United States.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes  also exist  between  South Korea  and North  Korea.  In
addition,  the  Underlying  Theme  Portfolios may  invest  in  Hong  Kong, which
reverted to Chinese administration on July 1, 1997. Investments in Hong Kong may
be subject to expropriation, nationalization  or confiscation, in which case  an
Underlying   Theme  Portfolio   could  lose   its  entire   investment  in  Hong
 
                  Statement of Additional Information Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Kong. In addition, the reversion of Hong Kong also presents a risk that the Hong
Kong dollar will be devalued and a risk of possible loss of investor  confidence
in Hong Kong's currency, stock market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in   the
securities of companies in emerging markets may entail special risks relating to
potential  political and  economic instability  and the  risks of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment,  convertibility of currencies into  U.S. dollars and on repatriation
of capital  invested. In  the event  of such  expropriation, nationalization  or
other  confiscation by any country, an Underlying Theme Portfolio could lose its
entire investment in any such country.
 
Emerging securities  markets are  substantially  smaller, less  developed,  less
liquid  and more volatile than the major securities markets. The limited size of
emerging securities markets and limited trading value in issuers compared to the
volume of  trading in  U.S. securities  could  cause prices  to be  erratic  for
reasons  apart  from factors  that  affect the  quality  of the  securities. For
example, limited market size may cause prices to be unduly influenced by traders
who control  large  positions.  Adverse publicity  and  investors'  perceptions,
whether  or  not  based on  fundamental  analysis,  may decrease  the  value and
liquidity of portfolio  securities, especially  in these  markets. In  addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience  of financial intermediaries, a lack of modern technology, the lack
of a sufficient capital base to expand business operations, and the  possibility
of permanent or temporary termination of trading.
 
Settlement  mechanisms in emerging securities markets  may be less efficient and
reliable than in more developed markets.  In such emerging securities there  may
be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and may  continue to  have  negative effects  on  the economies  and  securities
markets of certain emerging market countries.
 
    PRIVATIZATIONS.  The governments of some foreign countries have been engaged
in programs  of selling  part or  all of  their stakes  in government  owned  or
controlled   enterprises   ("privatizations").   The   Manager   believes   that
privatizations may offer opportunities for significant capital appreciation  and
intends to invest assets of the Underlying Theme Portfolios in privatizations in
appropriate  circumstances. In certain foreign countries, the ability of foreign
entities  such   as  the   Underlying  Theme   Portfolios  to   participate   in
privatizations may be limited by local law, or the terms on which the Underlying
Theme  Portfolios may be permitted to  participate may be less advantageous than
those for local investors.  There can be no  assurance that foreign  governments
will  continue to sell companies  currently owned or controlled  by them or that
privatization programs will be successful.

FUNDAMENTAL LIMITATIONS.  The  following  fundamental limitations  of  the  Fund
cannot  be changed without the affirmative vote of  the lesser of (i) 67% of the
Fund's shares represented at a meeting at which more than 50% of the outstanding
shares are  represented  or  (ii)  more  than  50%  of  the  outstanding  shares

The Fund will not:
 
        (1)  Issue senior securities or borrow  money, except as permitted under
    the 1940 Act and then  not in excess of 33  1/3% of the Fund's total  assets
    (including  the amount  of the senior  securities issued but  reduced by any
    liabilities not constituting senior securities) at the time of the  issuance
    or  borrowing, except that the Fund may borrow up to an additional 5% of its
    total assets (not including the amount borrowed) for temporary or  emergency
    purposes;
 
        (2)  Make loans, except through loans of portfolio securities or through
    repurchase agreements, provided that for  purposes of this restriction,  the
    acquisition  of bonds, debentures, other  debt securities or instruments, or
    participations or  other interests  therein  and investments  in  government
    obligations, commercial paper, certificates of deposit, bankers' acceptances
    or similar instruments will not be considered the making of a loan;
 
        (3)  Engage in the business of underwriting securities of other issuers,
    except to the extent that the Fund might be considered an underwriter  under
    the  federal securities laws in connection with its disposition of portfolio
    securities;
 
        (4) Purchase or sell real estate, except that investments in  securities
    of  issuers that  invest in real  estate and  investments in mortgage-backed
    securities,  mortgage  participations  or  other  instruments  supported  by
    interests in real estate are not subject to this limitation, and except that
    the  Fund may exercise rights under  agreements relating to such securities,
    including the right to  enforce security interests and  to hold real  estate
    acquired  by  reason  of such  enforcement  until  that real  estate  can be
    liquidated in an orderly manner; or
 
        (5) Purchase or sell physical commodities unless acquired as a result of
    owning securities or other instruments, but  the Fund may purchase, sell  or
    enter  into  financial  options  and  futures,  forward  and  spot  currency
    contracts, swap  transactions and  other financial  contracts or  derivative
    instruments.
 
Because of its investment objective and policies, the Fund will concentrate more
than  25% of  its assets  in the  mutual fund  industry. In  accordance with the
Fund's investment program set forth in the Prospectus, the Fund may invest  more
than  25% of its assets in the Underlying Theme Funds. In addition, the Fund has
adopted as a fundamental investment policy the classification as a "diversified"
fund under the  1940 Act, which  means that, with  respect to 75%  of its  total
assets it will invest no more than 5% of its assets in the securities of any one
issuer,  and  it  will purchase  no  more  than 10%  of  the  outstanding voting
securities of  any one  issuer. The  foregoing limitations,  however, shall  not
apply  to  U.S.  government  securities and  to  securities  issued  by open-end
investment companies.
 
NON-FUNDAMENTAL LIMITATIONS. The  following investment limitations  of the  Fund
are  non-fundamental and  may be  changed by  the vote  of the  Trust's Board of
Trustees without shareholder approval.
 
The Fund will not:
 
        (1) Invest more  than 15% of  its net assets  in illiquid securities,  a
    term  which means securities that cannot be disposed of within seven days in
    the ordinary course  of business at  approximately the amount  at which  the
    Fund  has valued the securities and includes, among other things, repurchase
    agreements maturing in more than seven days;
 
        (2) Purchase portfolio securities  while borrowings in  excess of 5%  of
    its total assets are outstanding;
 
        (3)   Purchase  securities  on  margin,  except  for  short-term  credit
    necessary for clearance of portfolio  transactions and except that the  Fund
    may make margin deposits in connection with its use of financial options and
    futures,  forward and spot  currency contracts, swap  transactions and other
    financial contract or derivative instruments;
 
                  Statement of Additional Information Page 21
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (4) Engage in short  sales of securities or  maintain a short  position,
    except that the Fund may maintain short positions in connection with its use
    of  financial options an futures, forward  and spot currency contracts, swap
    transactions and other financial contracts or derivative instruments; or
 
        (5) Purchase securities  of other  investment companies,  except to  the
    extent  permitted by the 1940 Act or  under the terms of any exemptive order
    granted by  the  SEC and  except  that this  limitation  does not  apply  to
    securities received or acquired as dividends, through offers of exchange, or
    as a result of reorganization, consolidation, or merger.
 
If a percentage restriction on investment or utilization of assets is adhered to
at  the  time of  an investment  or  transaction, a  later change  in percentage
ownership of a  security or kind  of securities resulting  from changing  market
values  or a  similar type of  event will not  be considered a  violation of the
Fund's policies or restrictions.
 
Notwithstanding the  forgoing investment  limitations, the  Fund may  invest  in
Underlying Theme Funds that have adopted investment limitations that may be more
or  less restrictive than those  listed above. As a  result, the Fund may engage
indirectly in investment  strategies that  are prohibited  under the  investment
limitations  listed  above.  The  investment  limitations  and  other investment
policies and restrictions  of each Underlying  Theme Fund are  described in  its
prospectus and statement of additional information.
 
Pursuant   to  Section  12(d)(1)(G)  of  the  1940  Act,  the  Fund  may  invest
substantially all of its assets in the Underlying Theme Funds.
 
INVESTMENT LIMITATIONS OF THE UNDERLYING THEME FUNDS AND PORTFOLIOS
FEEDER FUNDS
 
The Consumer Products and Services Fund, Financial Services Fund, Infrastructure
Fund and Natural Resources  Fund each has  the following fundamental  investment
policy  to enable  it to  invest in  the Global  Consumer Products  and Services
Portfolio, Global Financial Services Portfolio, Global Infrastructure  Portfolio
and Global Natural Resources Portfolio, respectively:
 
    Notwithstanding  any other investment  policy of the  Fund, the Fund may
    invest all of  its investable assets  (cash, securities and  receivables
    related  to  securities) in  an  open-end management  investment company
    having  substantially  the  same  investment  objective,  policies   and
    limitations as the Fund.
 
All  other fundamental  investment policies, and  the non-fundamental investment
policies, of each  Feeder Fund  and its corresponding  Portfolio are  identical.
Therefore,  although  the following  discusses the  investment policies  of each
Portfolio and  Global  Investment  Portfolio's Board  of  Trustees,  it  applies
equally to each Feeder Fund and the Company's Board
of Directors.
 
Each  Portfolio has adopted the  following investment limitations as fundamental
policies that (unless  otherwise noted) may  not be changed  without a  Required
Vote.  Whenever a Feeder Fund is requested to vote on a change in the investment
limitations of its corresponding Portfolio, that Feeder Fund will hold a meeting
of its shareholders and will cast its votes as instructed by its shareholders.
 
No Portfolio may:
 
        (1)  Buy   or  sell   real  estate   (including  real   estate   limited
    partnerships); however, each Portfolio 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;
 
        (2) Buy or  sell commodities  or commodity contracts,  except that  each
    Portfolio may purchase and sell financial and currency futures contracts and
    options  thereon,  and may  purchase  and sell  currency  forward contracts,
    options on foreign currencies and may otherwise engage in other transactions
    in foreign currencies;
 
        (3) Underwrite securities of  other issuers, except  to the extent  that
    the  disposition of  an investment position  may technically cause  it to be
    considered an underwriter as that term is defined under the 1933 Act;
 
        (4) Make loans, except that each Portfolio may purchase debt  securities
    and  enter  into  repurchase  agreements and  may  make  loans  of portfolio
    securities;
 
        (5) Purchase  securities on  margin, provided  that each  Portfolio  may
    obtain  such short-term  credits as  may be  necessary for  the clearance of
    purchases and sales of securities; except  that it may make margin  deposits
    in connection with futures contracts;
 
                  Statement of Additional Information Page 22
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (6) Borrow money except from banks not in excess of 33 1/3% of the value
    of  each Portfolio's total assets, (including the amount borrowed), less all
    liabilities and indebtedness  (other than the  borrowing). This  restriction
    shall  not  prevent  any  Portfolio from  entering  into  reverse repurchase
    agreements, provided  that  reverse  repurchase agreements,  and  any  other
    transactions  constituting borrowing by a Portfolio may not exceed one-third
    of that Portfolio's  total assets. Transactions  involving options,  futures
    contracts,  options on futures contracts  and forward currency contracts, as
    described in its  prospectus and  Statement of  Additional Information,  and
    reflected  in  the  Fund's  Prospectus  and  this  Statement  of  Additional
    Information, and collateral arrangements relating thereto will not be deemed
    to be borrowings;
 
        (7) Mortgage, pledge, or  hypothecate any of  its assets, provided  that
    this restriction shall not apply to the transfer of securities in connection
    with  any permissible borrowing or  to collateral arrangements in connection
    with permissible activities; or
 
        (8) Invest in direct interests or  leases in oil, gas, or other  mineral
    exploration  or development programs; however,  each Portfolio may invest in
    the securities of companies that engage in these activities.
 
In addition, each  Portfolio has adopted  as a fundamental  investment policy  a
classification as a "diversified" fund under the 1940 Act. This means that, with
respect  to 75% of a Portfolio's total assets,  no more than 5% will be invested
in the securities of  any one issuer,  and the Portfolio  will purchase no  more
than  10% of the  outstanding voting securities  of any one  issuer. This policy
cannot be changed without a Required Vote.
 
The following investment policies of each Portfolio are not fundamental policies
and may be changed  by vote of Global  Investment Portfolio's Board of  Trustees
without shareholder approval.
 
No Portfolio may:
 
        (1)  Invest in securities of an issuer if the investment would cause the
    Portfolio to own more than 10% of any class of securities of any one issuer;
 
        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;
 
        (3)  Invest  more than  15% of  its net  assets in  illiquid securities,
    including securities that are illiquid by virtue of the absence of a readily
    available market;
 
        (4) Invest more than 5% of  its total assets in securities of  companies
    having,  together with their predecessors, a record of less than three years
    of continuous operation;
 
        (5) Purchase or retain the securities of any issuer, if those individual
    officers and Trustees of the Portfolio, the Portfolio's investment  adviser,
    or  distributor,  each  owning  beneficially  more than  1/2  of  1%  of the
    securities of such issuer,  together own more than  5% of the securities  of
    such issuer;
 
        (6)  Enter into a futures contract, an  option on a futures contract, or
    an option on foreign currency traded  on a CFTC-regulated exchange, in  each
    case  other than for bona fide hedging purposes (as defined by the CFTC), if
    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5% of the liquidation value of the Portfolio's portfolio, after taking  into
    account  unrealized  profits  and  unrealized losses  on  any  contracts the
    Portfolio has entered into;
 
        (7) Borrow money  except for  temporary or emergency  purposes (not  for
    leveraging)  in excess  of 33  1/3% of  the value  of the  Portfolio's total
    assets (while borrowings exceed 5% of the Global Infrastructure  Portfolio's
    or  the Global  Natural Resources  Portfolio's total  assets, such Portfolio
    will not make any additional investments); and
 
        (8) Invest  more  than  10% of  its  total  assets in  shares  of  other
    investment  companies and may not invest more than 5% of its total assets in
    any one investment company or acquire more than 3% of the outstanding voting
    securities of any one investment company.
 
Investors should refer  to the  Underlying Theme Funds'  prospectus for  further
information  with respect to the investment objective of each Feeder Fund, which
may  not  be  changed  without  the  approval  of  its  shareholders,  and   its
corresponding Portfolio's investment objective, which may be changed without the
approval  of its interestholders, and  other investment policies, techniques and
limitations, which may or may not be changed without interestholder approval.
 
HEALTH CARE FUND
 
The Health  Care  Fund  has  adopted the  following  investment  limitations  as
fundamental  policies, which (unless otherwise noted) may not be changed without

The Health Care Fund may not:
 
        (1) Invest more than 10% of its total assets in securities which  cannot
    be readily resold to the public because of legal or contractual restrictions

        (2) Invest  in  companies  for  the purpose  of  exercising  control  or
    management;

        (4) Purchase  securities  on margin  or  make short  sales,  except  for
    short-term  credits necessary  for clearance of  portfolio transactions, and
    except that the  Health Care Fund  may make short  sales and maintain  short
    positions  and  may  make margin  deposits  in  connection with  its  use of
    options, futures contracts and options on futures contracts;
 
        (5) Underwrite securities of other  issuers, except to the extent  that,
    in  connection with the disposition of portfolio securities, the Health Care
    Fund may be deemed to be an underwriter under federal securities laws;
 
        (6)  Make  loans,  except  through  loans  of  portfolio  securities  as
    authorized   by  the  Health  Care  Fund's  prospectus  and  except  through
    repurchase agreements, provided  that for  purposes of  this limitation  the
    acquisition  of portfolio securities consistent  with the Health Care Fund's
    investment objective and policies shall not be deemed to be the making of  a
    loan;
 
        (7)  Purchase or  sell commodities  or commodity  contracts, except that
    consistent with the Health Care Fund's investment objective and policies  it
    may  use financial and currency futures  instruments and options thereon for
    hedging purposes;
 
        (8) Issue senior securities, except that for purposes of this limitation
    the Health Care Fund may borrow money in such amounts and in such fashion as
    is permitted under the 1940 Act and the rules thereunder;
 
        (9) Mortgage,  pledge  or hypothecate  or  in any  manner  transfer,  as
    security  for indebtedness, any securities owned  or held by the Health Care
    Fund, except as may  be necessary in  connection with permitted  borrowings;
    provided,  however, that this does not prohibit escrow, collateral or margin
    arrangements in connection with  its use of  options, futures contracts  and
    options on futures contracts;
 
       (10) Invest in oil, gas or mineral-related programs or leases; or
 
       (11) Purchase any security if as a result more than 5% of the Health Care
    Fund's  total  assets would  be invested  in  securities of  companies which
    together with any predecessors  have been in operation  for less than  three
    years.
 
In addition, the Health Care Fund has adopted as a fundamental investment policy
the classification as a "diversified" fund under the 1940 Act, which means that,
with respect to 75% of its total assets, no more than 5% will be invested in the
securities  of any  one issuer,  and it will  purchase no  more than  10% of the
outstanding voting securities of any one  issuer. This policy cannot be  changed
without a Required Vote.
 
Investors  should refer  to the Underlying  Theme Funds'  prospectus for further
information with respect to the  Health Care Fund's investment objective,  which
may  not  be changed  without a  Required Vote,  and other  investment policies,
techniques and limitations, which may be changed without shareholder approval.

    partnerships);  however,  the  Telecommunications Fund  may  invest  in debt

                          GT GLOBAL NEW DIMENSION FUND
 
        (3) Engage in the business of underwriting securities of other  issuers,

    This restriction shall not prevent the Telecommunications Fund from entering
    into   reverse  repurchase  agreements,  provided  that  reverse  repurchase
    agreements, and any other transactions constituting borrowing by it may  not
    exceed  one-third  of  its  total  assets.  Transactions  involving options,

    contracts,  as  described  in  its prospectus  and  Statement  of Additional
    Information, and reflected in  the Fund's Prospectus  and this Statement  of
    Additional  Information, and  collateral arrangements  relating thereto will
    not be deemed to be borrowings;
 
        (7) Mortgage, pledge, or  hypothecate any of  its assets, provided  that

    with  any permissible borrowing or  to collateral arrangements in connection
    with permissible activities; or
 
        (8) Invest in direct interests or  leases in oil, gas, or other  mineral

    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5% of  the liquidation  value of  the Telecommunications  Fund's  portfolio,
    after  taking into account  unrealized profits and  unrealized losses on any
    contracts the Telecommunications Fund has entered into; or
 
        (7) Borrow money  except for  temporary or emergency  purposes (not  for
    leveraging)  not in excess of 33 1/3% of the value of the Telecommunications

                  Statement of Additional Information Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
The Telecommunications Fund has the authority to  invest up to 10% of its  total
assets  in shares  of other investment  companies and in  real estate investment
trusts. The Telecommunications  Fund may not  invest more than  5% of its  total
assets  in any one investment company or acquire more than 3% of the outstanding
voting securities of any one investment company.
 
Investors should refer  to the  Underlying Theme Funds'  prospectus for  further
information  with respect to the Telecommunications Fund's investment objective,
which may not be changed without a Required Vote, and other investment policies,
techniques and limitations, which may be changed without shareholder approval.
 
If a  percentage  restriction on  investment  or  utilization of  assets  in  an
investment  policy or  restriction is  adhered to at  the time  an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market  values or a  similar type of  event will not  be
considered  a violation of the  Underlying Theme Portfolio's investment policies
or restrictions. An Underlying Theme Portfolio may exchange securities, exercise
conversion or subscription rights, warrants  or other rights to purchase  common
stock  or other equity securities and may  hold, except to the extent limited by
the 1940 Act, any such securities  so acquired without regard to the  Underlying
Theme Portfolio's investment policies and restrictions. The original cost of the
securities  so acquired will be included  in any subsequent determination of the
Underlying  Theme  Portfolio's   compliance  with   the  investment   percentage
limitations referred to above and in the Prospectus.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
 
All  orders  for the  purchase  or sale  of  portfolio securities  for  the Fund
(normally shares of the Underlying Theme Funds) are placed on behalf of the Fund
by the  Manager. As  stated in  the  Prospectus, the  Manager will  exercise  no
discretion in investing the assets of the Fund other than to make investments in
money market instruments and to rebalance the percentage of the Fund's assets in
each Underlying Theme Fund.
 
Subject  to  policies  established  by  the  applicable  Board,  the  Manager is
responsible for the  execution of each  Underlying Theme Portfolio's  securities
transactions  and the selection of  broker/dealers who execute such transactions
on behalf of  each Underlying  Theme Portfolio. In  executing transactions,  the
Manager  seeks the best net results  for each Underlying Theme Portfolio, taking
into account  such factors  as  the price  (including the  applicable  brokerage
commission  or dealer  spread), size of  the order, difficulty  of execution and
operational facilities  of the  firm involved.  Although the  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 each Underlying Theme Portfolio may engage in soft dollar arrangements for
research services, as  described below, it  has no obligation  to deal with  any
broker/dealer   or  group  of  broker/dealers  in  the  execution  of  portfolio
transactions.
 
Consistent with the interests  of each Underlying  Theme Portfolio, the  Manager
may select broker/dealers to execute that Underlying Theme Portfolio's portfolio
transaction  on the basis of the research and brokerage services they provide to
the Manager for  its use  in managing that  Underlying Theme  Portfolio and  its
other  advisory accounts. Such services may include furnishing analyses, reports
and information concerning issuers, industries, securities, geographic  regions,
economic  factors and trends,  portfolio strategy, and  performance of accounts;
and  effecting  securities  transactions  and  performing  functions  incidental
thereto  (such  as clearance  and settlement).  Research and  brokerage services
received from such broker are in addition  to, and not in lieu of, the  services
required  to  be  performed  by  the  Manager  under  investment  management and
administration contracts. A commission  paid to such broker  may be higher  than
that  which another qualified  broker would have charged  for effecting the same
transaction, provided  that  the 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 Underlying Theme Portfolio and  its
other  clients  and that  the total  commissions paid  by that  Underlying Theme
Portfolio will be  reasonable in relation  to the benefits  it receive over  the
long  term.  Research services  may also  be received  from dealers  who execute
portfolio 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 an  Underlying Theme  Portfolio toward  payment of  its
expenses, such as custodian fees.

Investment  decisions for an Underlying Theme 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 an Underlying Theme Portfolio.
In such cases, simultaneous transactions may occur. Purchases or sales are  then
allocated  as to price  or amount in a  manner deemed fair  and equitable to all
accounts involved. While in  some cases this practice  could have a  detrimental
effect  upon the price  or value of the  security as far  as an Underlying Theme
Portfolio is concerned, in  other cases the  Manager believes that  coordination
and the ability to participate in volume transactions will be beneficial to that
Underlying Theme Portfolio.
 
Under  a policy adopted  by the applicable  Board, 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 Underlying Theme  Funds and the other portfolios for which
the  Manager  serves  as  investment  manager  or  administrator  in   selecting
broker/dealers for the execution of portfolio transactions. This policy does not
imply  a commitment to execute portfolio transactions through all broker/dealers
that sell shares of the Underlying Theme Funds and such other portfolios.
 
Each Underlying  Theme Portfolio  contemplates  purchasing most  foreign  equity
securities  in OTC markets or stock exchanges  located in the countries in which
the respective principal offices  of the issuers of  the various securities  are
located,  if that is  the best available  market. The fixed  commissions paid in
connection with most such foreign  stock transactions generally are higher  than
negotiated  commissions on U.S. transactions. There generally is less government
supervision and regulation of  foreign stock exchanges and  brokers than in  the
United  States. Foreign security settlements may in some instances be subject to
delays and related administrative uncertainties.
 
Foreign equity securities may  be held by an  Underlying Theme Portfolio in  the
form  of ADRs,  ADSs, EDRs, CDRs  or securities convertible  into foreign equity
securities. ADRs,  ADSs, EDRs  and CDRs  may be  listed on  stock exchanges,  or
traded  in the OTC markets in  the United States or Europe,  as the case may be.
ADRs, like other  securities traded  in the United  States, will  be subject  to
negotiated  commission rates. The foreign and domestic debt securities and money
market instruments  in  which  an  Underlying Theme  Portfolio  may  invest  are
generally traded in the OTC markets.
 
An  Underlying Theme  Portfolio does  not have any  obligation to  deal with any
broker/dealer  or  group  of  broker/dealers  in  the  execution  of  securities
transactions. Each Underlying Theme Portfolio contemplates that, consistent with
the  policy of  obtaining the  best net  results, brokerage  transactions may be
conducted through certain  companies that  are members  of Liechtenstein  Global
Trust.  Both Boards have 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.

- --------------------------------------------------------------------------------
 
MANAGEMENT SERVICES RELATING TO THE FUND
The  Manager acts as  the manager for the  Fund pursuant to  a contract with the
Trust. The Manager  receives no fees  for providing management  services to  the
Fund.
 
DISTRIBUTION SERVICES RELATING TO THE FUND
The  Fund's Class A, Class B and Class C shares are offered continuously through
the Fund's principal underwriter and distributor, GT Global, on a "best efforts"
basis pursuant  to separate  Distribution  Contracts between  the Trust  and  GT
Global.
 
As  described in the  Prospectus, the Trust has  adopted a separate Distribution
Plan with respect to  the Class A,  Class B and  Class C shares  of the Fund  in
accordance  with Rule 12b-1 under the 1940 Act  (each a "Class A Plan," "Class B
Plan," and "Class C Plan," respectively, and collectively, "Plans"). The rate of
payments by the Fund under the Plans, as described in the Prospectus, may not be
increased without  the  approval  of  the majority  of  the  outstanding  voting
securities of the 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.
 
In approving the Plans, the Trustees  determined that the adoption of the  Plans
was in the best interests of the shareholders of the Fund. Agreements related to
the  Plans  must also  be approved  by such  vote of  the Trustees,  including a
majority of Trustees who are not  "interested persons" of the Trust (as  defined
in  the 1940 Act) and who have no  direct or indirect financial interests in the
operation of the Plans, or in any agreement related thereto.
 
Each Plan requires  that, at least  quarterly, the Trustees  review the  amounts
expended thereunder and the purposes for which such expenditures were made. Each
Plan  requires that so long as it is  in effect, the selection and nomination of
Trustees who are not "interested persons" of the Trust will be committed to  the
discretion  of the Trustees  who are not  "interested persons" of  the Trust, as
defined in the 1940 Act.
 
As discussed in  the Prospectus, GT  Global collects sales  charges on sales  of
Class A shares of the Fund, retains certain amounts of such charges and reallows
other amounts of such charges to broker/dealers that sell shares.
 
GT  Global receives any contingent deferred sales charges ("CDSCs") payable with
respect to redemptions of  Class B shares,  Class C shares  and certain Class  A
shares.
 
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
The  Transfer  Agent  has  been  retained by  the  Fund  to  perform shareholder
servicing, reporting  and general  transfer agent  functions for  it. 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 is also reimbursed for its out-of-pocket expenses for such  items
as  postage,  forms,  telephone  charges, stationery  and  office  supplies. The
Manager also serves as the Fund's pricing and accounting agent. See  "Additional
Information -- Special Servicing Agreement."

                            VALUATION OF FUND SHARES
 
- --------------------------------------------------------------------------------
 
As  described in the Prospectus,  the Fund's net asset  value per share for each
class of shares  is determined each  day on  which the New  York Stock  Exchange
("NYSE")  is  open for  business ("Business  Day")  as of  the close  of regular
trading on the NYSE (currently 4:00 p.m. Eastern Time, unless weather, equipment
failure or other factors contribute to an earlier closing time). Currently,  the
NYSE  is  closed on  weekends  and on  certain  days relating  to  the following
holidays: New Year's Day, Presidents' Day, Good Friday, Memorial Day, July  4th,
Labor Day, Thanksgiving Day and Christmas Day.
 
The  value of the shares  of the Underlying Theme Funds  will be their net asset
value at the time the net asset value of the Fund is determined.

- --------------------------------------------------------------------------------
 
PAYMENT AND TERMS OF OFFERING
Payment for Class  A, Class B  or Class C  shares of the  Fund purchased  should
accompany  the purchase order, or funds should be wired to the Transfer Agent as
described in  the  Prospectus. Payment  for  Fund  shares, 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 Class  A, Class B  or
Class C shares is canceled due to nonpayment (for example, on account of a check
returned  for "not  sufficient funds"),  the person who  made the  order will be
responsible for any loss incurred by the Underlying Theme Fund by reason of such
cancellation, and if such  purchaser is a shareholder,  the Fund shall have  the
authority  as agent of the shareholder to redeem shares in his or her account at
their then-current net asset value per share to reimburse the Fund for the  loss
incurred.  Investors whose purchase orders have  been canceled due to nonpayment
may be prohibited from placing future orders.
 
The Fund  reserves the  right  at any  time to  waive  or increase  the  minimum
requirements applicable to initial or subsequent investments with respect to any
person  or class of persons.  An order to purchase shares  is not binding on the
Fund until it  has been confirmed  in writing  by the Transfer  Agent (or  other
arrangements  made with the Fund, in the  case of orders utilizing wire transfer
of funds, as described above) and payment has been received. To protect existing
shareholders, the Fund reserves the right to reject any offer for a purchase  of
shares by any individual.
 
SALES OUTSIDE THE UNITED STATES
Sales  of Fund shares made through brokers  outside the United States will be at
net asset value plus a sales commission,  if any, established by that broker  or
by  local law. Such  a commission, if  any, may be  more or less  than the sales
charges listed in the sales charge table included in the Prospectus.
 
AUTOMATIC INVESTMENT PLAN -- CLASS A, CLASS B AND CLASS C SHARES
To establish  participation in  the Fund's  Automatic Investment  Plan  ("AIP"),
investors  or their broker/dealers should specify  whether investment will be in
Class A, Class B or  Class C shares and should  send the following documents  to
the  Transfer Agent: (1) an AIP Application;  (2) a Bank Authorization Form; and
(3) a voided personal check from the pertinent bank account. The necessary forms
are provided at  the back of  the Prospectus. Provided  that an investor's  bank
accepts  the Bank  Authorization Form, investment  amounts will be  drawn on the
designated dates (monthly on the 25th day or beginning quarterly on the 25th day
of the  month  the  investor  first  selects) in  order  to  purchase  full  and
fractional  shares of the Fund  at the public offering  price determined on that
day. In the  event that the  25th day falls  on a Saturday,  Sunday or  holiday,
shares  will be purchased  on the next  business day. If  an investor's check is
returned because of insufficient funds or a stop payment order or if the account
is closed, the AIP may be discontinued, and any share purchase made upon deposit
of such check may be canceled.  Furthermore, the shareholder will be liable  for
any loss incurred by the
 
                  Statement of Additional Information Page 31
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Fund  by reason of such  cancellation. Investors should allow  one month for the
establishment of an AIP. An AIP may  be terminated by the Transfer Agent or  the
Fund  upon thirty days' written notice or by the participant at any time without
penalty, upon written notice to the Fund or the Transfer Agent.
 
LETTER OF INTENT -- CLASS A SHARES
The Letter  of  Intent ("LOI")  is  not a  binding  obligation to  purchase  the
indicated amount. During such time as 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 capital gain  distributions on escrowed  shares will be
reinvested in additional Class  A shares or  paid in cash,  as specified by  the
shareholder.  If the intended  investment is not  completed within the specified
thirteen-month period,  the purchaser  must remit  to GT  Global the  difference
between  the sales charge  actually paid and  the sales charge  which would have
been applicable if the total Class A  purchases had been made at a single  time.
If  this  amount is  not  paid to  GT Global  within  twenty days  after written
request, the appropriate  number of  escrowed shares  will be  redeemed and  the
proceeds paid to GT Global.
 
A  registered investment adviser,  trust company or  trust department seeking to
execute an LOI  as a single  purchaser with  respect to accounts  over which  it
exercises  investment discretion is required to  provide the Transfer Agent with
information establishing that it has discretionary authority with respect to the
money invested (e.g., by providing a  copy of the pertinent investment  advisory
agreement).  Class A shares purchased in this manner must be registered with the
Transfer Agent  so that  only the  investment adviser,  trust company  or  trust
department,  and  not the  beneficial  owner, will  be  able to  place purchase,
redemption and exchange orders.
 
CONVERSION OF CLASS B SHARES
Class B shares of the  Fund automatically will convert to  Class A shares as  of
the close of business on the last business day of the month in which the seventh
anniversary  of the  initial issuance  of such  Class B  shares occurs.  For the
purpose of calculating  the holding period  required for conversion  of Class  B
shares,  the initial issuance of Class B shares shall mean (i) the date on which
such Class B shares were issued, or (ii) for Class B shares obtained through  an
exchange,  or a  series of  exchanges, the  date on  which the  original Class B
shares were  issued. For  purposes of  conversion  to Class  A, Class  B  shares
purchased  through the reinvestment of dividends and other distributions paid in
respect of Class B shares will be held in a separate sub-account. Each time  any
Class  B shares in  the shareholder's regular  account (other than  those in the
sub-account) convert to Class A, a pro rata portion of the Class B shares in the
sub-account will also convert to Class A. The portion will be determined by  the
ratio  that the shareholder's Class B shares  converting to Class A bears to the
shareholder's total  Class B  shares not  acquired through  dividends and  other
distributions.
 
The  availability  of  the  conversion  feature  is  subject  to  the continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions  paid  on  Class  A  and  Class  B  shares  will  not  result   in
"preferential  dividends" under the Internal Revenue  Code and the conversion of
shares does not constitute a taxable event. If the conversion feature ceased  to
be available, the Class B shares would not be converted and would continue to be
subject  to the higher ongoing expenses of the Class B shares beyond the seventh
anniversary of the initial issuance of such  Class B shares. The Manager has  no
reason  to believe  that this condition  for the availability  of the conversion
feature will not be met.
 
INDIVIDUAL RETIREMENT ACCOUNTS ("IRAS") AND OTHER TAX-DEFERRED PLANS
Class A,  Class  B or  Class  C shares  of  the 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 (the "Code"),  as
well  as  for  qualified retirement  plans  described  in Code  Section  401 and
custodial accounts complying with Code Section 403(b)(7).
 
IRAS: If you have earned income from employment (including self-employment), you
can contribute each year to an IRA up  to the lesser of (1) $2,000 for  yourself
or  $4,000  for  you and  your  spouse,  regardless of  whether  your  spouse is
employed, or (2) 100% of compensation. Some  individuals may be able to take  an
income tax deduction for the contribution. Regular contributions may not be made
for  the year  you become 70  1/2 or  thereafter. Unless your  and your spouse's
earnings exceed  a certain  level, you  also may  establish an  "education  IRA"
and/or  a "Roth  IRA." Although  contributions to  these new  types of  IRAs are
nondeductible,  withdrawals   from  them   will   be  tax-free   under   certain
circumstances.  Please  consult  your  tax  advisor  for  more  information. IRA
applications are available from brokers or GT Global.
 
ROLLOVER IRAS: Individuals who  receive distributions from qualified  retirement
plans  (other than  required distributions) and  who wish to  keep their savings
growing tax-deferred  can  roll  over  (or make  a  direct  transfer  of)  their
distribution  to a  Rollover IRA. These  accounts can also  receive rollovers or
transfers from an existing  IRA. If an "eligible  rollover distribution" from  a
qualified  employer-sponsored retirement plan is not  directly rolled over to an
IRA (or certain

qualified plans), withholding at  the rate of 20%  will be required for  federal
income  tax  purposes. A  distribution  from a  qualified  plan that  is  not an
"eligible rollover  distribution," including  a distribution  that is  one of  a
series of substantially equal periodic payments, generally is subject to regular
wage  withholding or withholding at  the rate of 10%  (depending on the type and
amount of the distribution), unless you elect not to have any withholding apply.
Please consult your tax advisor for more information.
 
SEP-IRAS: Simplified  employee  pension  plans ("SEPs"  or  "SEP-IRAs")  provide
self-employed  individuals (and any eligible employees) with benefits similar to
Keogh plans (i.e.,  self-employed individual retirement  plans) or Code  Section
401(k)   plans,  but  with  fewer   administrative  requirements  and  therefore
potentially lower annual administration expenses.
 
CODE SECTION 403(b)(7) CUSTODIAL ACCOUNTS: Employees of public schools and  most
other  tax-exempt organizations can make  pre-tax salary reduction contributions
to these accounts.
 
PROFIT-SHARING  (INCLUDING   SECTION   401(k))  AND   MONEY   PURCHASE   PENSION
PLANS:  Corporations  and other  employers can  sponsor these  qualified defined
contribution plans  for  their employees.  A  Section  401(k) plan,  a  type  of
profit-sharing  plan, additionally permits the eligible, participating employees
to make  pre-tax salary  reduction  contributions to  the  plan (up  to  certain
limits).
 
SIMPLE  PLANS: Employers with  no more than  100 employees that  do not maintain
another retirement  plan  may  establish  a Savings  Incentive  Match  Plan  for
Employees  ("SIMPLE") either  as separate  IRAs or as  part of  a Section 401(k)
plan. SIMPLEs are not  subject to the  complicated nondiscrimination rules  that
generally apply to qualified retirement plans.
 
EXCHANGES
Class  A and Class B shares of the Fund  may be exchanged for shares 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. Class A shares of the Fund  may be exchanged only for Class A  shares
of  other GT Global  Mutual Funds. Class B  shares of the  Fund may be exchanged
only for Class B shares of other GT Global Mutual Funds. Exchange privileges for
Class C shares will not be available until other GT Global Mutual Funds commence
offering Class C shares.  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 the funds  upon sixty days  prior written notice  to the shareholders of
such 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  the investment  objective(s) of the
fund.
 
TELEPHONE REDEMPTIONS
A corporation or  partnership wishing to  utilize telephone redemption  services
must  submit a "Corporate Resolution" or "Certificate of Partnership" indicating
the names, titles and the required number of signatures of persons authorized to
act on  its  behalf.  The  certificate  must be  signed  by  a  duly  authorized
officer(s),  and,  in the  case of  a  corporation, the  corporate seal  must be
affixed. All shareholders may request that redemption proceeds be transmitted by
bank wire upon request directly to the shareholder's predesignated account at  a
domestic  bank or savings institution if the proceeds are at least $1,000. Costs
in connection with the administration  of this service, including wire  charges,
currently  are borne by the Fund. Proceeds of less than $1,000 will be mailed to
the shareholder's registered address of record. The Fund and the Transfer  Agent
reserve  the right to refuse any  telephone instructions and may discontinue the
aforementioned redemption options upon thirty days' written notice.
 
SYSTEMATIC WITHDRAWAL PLAN
Shareholders owning Class A, Class B or Class C shares of the Fund with a  value
of  $10,000 or more may establish a Systematic Withdrawal Plan ("SWP"). Under an
SWP, a shareholder will receive monthly or quarterly payments, in amounts of not
less than $100 per  payment, through the automatic  redemption of the  necessary
number  of shares on the designated dates  (monthly on the 25th day or quarterly
on the 25th day of January, April, July and October). In the event that the 25th
day falls on a Saturday,  Sunday or holiday, the  redemption will take place  on
the prior business day. Certificates, if any, for the shares being redeemed must
be  held by the  Transfer Agent. Checks  will be made  payable to the designated
recipient and  mailed within  seven days.  If the  recipient is  other than  the
registered  shareholder, the signature of each shareholder must be guaranteed on
the  SWP  application  (see  "How  to  Redeem  Shares"  in  the  Prospectus).  A
corporation  (or partnership)  must also  submit a  "Corporation Resolution" (or
"Certificate of Partnership")  indicating the names,  titles, and signatures  of
the individuals authorized to act on its behalf, and the SWP application must be
signed by a duly authorized officer(s) and the corporate seal affixed.
 
                  Statement of Additional Information Page 33
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
With  respect to a SWP, the maximum annual  SWP withdrawal is 12% of the initial
account value.  Withdrawals  in excess  of  12%  of the  initial  account  value
annually  may result  in assessment of  a contingent deferred  sales charge. See
"How to Invest" in the Prospectus.
 
Shareholders should be aware that such systematic withdrawals may deplete or use
up entirely the initial investment and result in the realization of long-term or
short-term capital gains or losses. The SWP may be terminated at any time by the
Transfer Agent or the Fund upon thirty days' written notice or by a  shareholder
upon  written notice to the Fund or the Transfer Agent. Applications and further
details regarding  establishment of  an SWP  are  provided at  the back  of  the
Prospectus.
 
SUSPENSION OF REDEMPTION PRIVILEGES
The  Fund may suspend redemption privileges or  postpone the date of payment for
more than seven days after a redemption order is received during any period  (1)
when  the NYSE is closed  other than customary weekend  and holiday closings, or
trading on the NYSE is restricted as directed by the SEC, (2) when an  emergency
exists,  as defined by the SEC, which  would prohibit the Fund or the Underlying
Theme Portfolios from  disposing of  portfolio securities  owned by  them or  in
fairly  determining 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  that would,  in  the
opinion  of the Trust's Board  of Trustees, make it  undesirable for the Fund to
pay for all redemptions in cash. In such cases, the Board may authorize  payment
to  be made  in portfolio  securities or other  property of  the Fund, so-called
"redemptions in kind." Payment  of redemptions in kind  will be made in  readily
marketable  securities.  Such  securities  would be  valued  at  the  same value
assigned to  them in  computing  the net  asset  value per  share.  Shareholders
receiving  such  securities  would incur  brokerage  costs in  selling  any such
securities so received. However, despite the foregoing, the Trust has filed with
the SEC an election pursuant to Rule  18f-1 under the 1940 Act. This means  that
the Fund will pay in cash all requests for redemption made by any shareholder of
record, limited in amount with respect to each shareholder during any ninety-day
period to the lesser of $250,000 or 1% of the net asset value of the Fund at the
beginning  of such  period. This  election will be  irrevocable so  long as Rule
18f-1 remains in effect,  unless the SEC by  order upon application permits  the
withdrawal of such election.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUND
To  continue to qualify for treatment  as a regulated investment company ("RIC")
under the Code, the  Fund must distribute to  its shareholders for each  taxable
year at least 90% of its investment company taxable income (consisting generally
of  net  investment  income  and  net  short-term  capital  gain) ("Distribution
Requirement") and must meet several additional requirements. These  requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each  taxable year from dividends, interest, payments with respect to securities
loans and  gains from  the sale  or other  disposition of  securities, or  other
income  derived with respect to its business  of investing in securities; (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 (including the Underlying Theme Funds)  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, including the Underlying Theme Funds) of any one issuer.
 
The  Fund will invest its  assets in shares of  the Underlying Theme Funds, cash
and money market  instruments. Accordingly,  the Fund's income  will consist  of
distributions  from  the Underlying  Theme Funds,  net  gains realized  from the
disposition of Underlying Theme Fund shares and interest. If an Underlying Theme
Fund qualifies for treatment as a RIC under the Code -- each has done so for its
past taxable years and intends to continue  to do so for its current and  future
taxable years -- (1) dividends paid to the Fund from the Underlying Theme Fund's
investment  company taxable  income (which  may include  net gains  from certain
foreign currency transactions) will be taxable to the Fund as ordinary income to
the extent  of  the  Underlying  Theme  Fund's  earnings  and  profits  and  (2)
distributions paid to the Fund from the Underlying Theme Fund's net capital gain
(the  excess of  net long-term capital  gain over net  short-term capital loss),
when designated as such, will be taxable to the Fund as long-term capital gains,
regardless of how long the Fund has held the Underlying Theme Fund's shares.  If
shares  of an Underlying Theme Fund are purchased within 30 days before or after
redeeming at  a  loss, other  shares  of  that Underlying  Theme  Fund  (whether
pursuant to a rebalancing of the Fund's portfolio or otherwise) all or a part of
the  loss will not be deductible by the Fund and instead will increase its basis
for the newly purchased shares.
 
Although an Underlying Theme Fund will be eligible to elect to "pass-through" to
its shareholders (including the Fund) the benefit of the foreign tax credit with
respect to any foreign and  U.S. possessions income taxes  it pays if more  than
50%  in the value of its total assets  at the close of any taxable year consists
of securities of foreign  corporations, the Fund will  not qualify to pass  that
benefit  through to  its shareholders because  of its inability  to satisfy that
asset test.
 
The Fund will be subject to a nondeductible 4% excise tax to the extent it fails
to distribute by the end of any calendar year substantially all of its  ordinary
income  for that year and capital gain net income for the one-year period ending
on October 31 of that year, plus certain other amounts.
 
TAXATION OF THE FUND'S SHAREHOLDERS
Dividends  and  other  distributions  declared  by  the  Fund,  and  payable  to
shareholders  of record as  of a date,  in October, November  or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during  the following  January. Accordingly,  those distributions  will  be
taxed to shareholders for the year in which that December 31 falls.
 
A  portion of  the dividends from  the Fund's investment  company taxable income
(whether paid in cash  or reinvested in additional  shares) may be eligible  for
the  dividends-received deduction allowed to  corporations. The eligible portion
may not exceed the total of the Fund's share of the aggregate dividends received
by each  Underlying  Theme  Fund  from  U.S.  corporations.  However,  dividends
received  by  a  corporate  shareholder  and  deducted  by  it  pursuant  to the
dividends-received deduction  may  be  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
 
                  Statement of Additional Information Page 35
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 the Fund to a shareholder  who, as to the United States, is  a
nonresident  alien individual, nonresident alien fiduciary of a trust or estate,
foreign corporation  or foreign  partnership ("foreign  shareholder")  generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will not apply, however, to a dividend paid by the Fund to a foreign
shareholder  that is "effectively connected with the  conduct of a U.S. trade or
business," in which case the  reporting and withholding requirements  applicable
to  domestic shareholders will apply. A distribution  of net capital gain by the
Fund to a foreign shareholder generally  will be subject to U.S. federal  income
tax  (at the rates applicable  to domestic persons) only  if the distribution is
"effectively connected"  or the  foreign shareholder  is treated  as a  resident
alien individual for federal income tax purposes.
 
The  foregoing  is a  general  and abbreviated  summary  of certain  federal tax
considerations affecting the Fund and  its shareholders. Investors are urged  to
consult their own tax advisers for more detailed information and for information
regarding  any  foreign,  state  and  local  taxes  applicable  to distributions
received from the Fund.

                             ADDITIONAL INFORMATION
 
- --------------------------------------------------------------------------------
 
SPECIAL SERVICING AGREEMENT
Subject to the receipt of an  order pursuant to a pending exemptive  application
with the Securities and Exchange Commission and a private letter ruling pursuant
to  a  pending request  therefor with  the Internal  Revenue Service,  a Special
Servicing Agreement (the  "Service Agreement")  will be entered  into among  the
Manager,  the Underlying Theme Funds, GT Global Investor Services, Inc., and the
Trust. The  Service  Agreement  will  provide  that,  if  the  officers  of  any
Underlying  Theme Fund,  at the direction  of the Board  of Directors, determine
that the aggregate expenses of the Fund  are less than the estimated savings  to
the  Underlying Theme Fund from the operation  of the Fund, the Underlying Theme
Fund will bear those expenses  in proportion to the  average daily value of  its
shares  owned by the Fund and/or the number of shareholder accounts at the Fund.
No Underlying Theme  Fund will  bear such expenses  in excess  of the  estimated
savings  to  it.  Such  savings  are  expected  to  result  primarily  from  the
elimination of numerous separate  shareholder accounts which  are or would  have
been invested directly in the Underlying Theme Funds and the resulting reduction
in  shareholder servicing costs. In this regard, the shareholder servicing costs
to any Underlying Theme Fund for  servicing one account registered to the  Trust
would  be significantly less than the cost to that same Underlying Theme Fund of
servicing the same pool of assets contributed in the typical fashion by a  large
group  of individual shareholders owning small accounts in each Underlying Theme
Fund. If  the  Fund's  costs  exceed the  aggregate  estimated  savings  to  the
Underlying Theme Funds, the Manager will pay the excess on behalf of the Fund.
 
Rule 12b-1 distribution and service fees will not be paid in accordance with the
Service  Agreement. Nor will certain non-recurring and extraordinary expenses be
payable in accordance therewith including: the fees and costs of actions,  suits
or  proceedings and any  penalties or damages in  connection therewith, to which
the Trust and/or the Fund  may incur directly, or may  incur as a result of  its
legal  obligation  to  provide  indemnification to  its  officers,  trustees and
agents; the fees and  costs of any governmental  investigation and any fines  or
penalties  in  connection therewith;  and any  federal, state  or local  tax, or
related interest penalties  or additions  to tax,  incurred, for  example, as  a
result  of the Trust's  failure to distribute  all of its  income and gains, its
failure to  qualify as  a RIC  under the  Code, or  failure to  timely file  any
required  tax  returns or  other filings.  Amounts not  payable pursuant  to the
Service Agreement will be paid by the Fund.

SHAREHOLDER LIABILITY
Under certain circumstances,  shareholders of  the Fund may  be held  personally
liable  for  the  obligations of  the  Fund.  The Trust's  Declaration  of Trust
provides that shareholders shall  not be subject to  any personal liability  for
the  acts  or  obligations of  the  Fund or  the  Trust and  that  every written
agreement, obligation or  other undertaking made  or issued by  the Fund or  the
Trust  shall  contain  a  provision  to the  effect  that  shareholders  are not
personally  liable   thereunder.  The   Declaration   of  Trust   provides   for
indemnification  out  of the  Trust's  assets under  certain  circumstances, and
further provides that the Trust shall,  upon request, assume the defense of  any
act  or obligation of the Fund or the Trust and that the Fund will indemnify the
shareholder for all legal and other expenses incurred therewith. Thus, the  risk
of  any shareholder's  incurring financial  loss beyond  his or  her investment,
because of this theoretical shareholder  liability, is limited to  circumstances
in which the Fund or the Trust itself would be unable to meet its obligations.

                               INVESTMENT RESULTS
 
- --------------------------------------------------------------------------------
 
STANDARDIZED RETURNS
The  Fund's "Standardized Returns," as referred to in the Prospectus (see "Other
Information --  Performance  Information"  in  the  Prospectus),  is  calculated
separately  for Class  A, Class B  and Class C  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) =  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 Trust's Board of Trustees; and (4) a
complete redemption at the end of any period illustrated.
 
NON-STANDARDIZED RETURNS
In  addition   to  Standardized   Returns,  the   Fund  also   may  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,  Class B and Class C  shares of the Fund and
may be calculated according to several different formulas.
 
                  Statement of Additional Information Page 37
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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)  =  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.
 
The  Fund's investment results will vary from time to time depending upon market
conditions, the composition of each Underlying Theme Portfolio's portfolio,  and
operating  expenses of the Fund,  so that current or  past yield or total return
should not be considered  representative of what an  investment in the Fund  may
earn in any future period. These factors and possible differences in the methods
used  in calculating investment results should  be considered when comparing the
Fund's investment results  with those published  for other investment  companies
and  other investment  vehicles. The  Fund's results  also should  be considered
relative to  the  risks associated  with  the Fund's  investment  objective  and
policies.
 
IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKETS
The Fund and GT Global may from time to time in advertisements, sales literature
and  reports furnished to  present or prospective  shareholders compare the Fund
with the following, among others:
 
        (1) The Consumer Price Index ("CPI"), which is a measure of the  average
    change  in prices over time  in a fixed market  basket of goods and services
    (e.g., food,  clothing, shelter,  fuels, transportation  fares, charges  for
    doctors' and dentists' services, prescription medicines, and other goods and
    services  that people  buy for day-to-day  living). There  is inflation risk
    which does not affect a security's value but its purchasing power, i.e.  the
    risk of changing price levels in the economy that affects security prices or
    the price of goods and services.
 
        (2)  Data  and  mutual fund  rankings  published or  prepared  by Lipper
    Analytical  Data  Services,  Inc.  ("Lipper"),  CDA/Wiesenberger  Investment
    Companies  Service ("CDA/Wiesenberger"),  Morningstar, Inc.,  Micropal, Inc.
    and/or other  companies that  rank and/or  compare mutual  funds by  overall
    performance,  investment  objectives,  assets,  expense  levels,  periods of
    existence and/or other factors. In this  regard the Fund may be compared  to
    its  "peer group" as defined by Lipper, CDA/Wiesenberger, Morningstar and/or
    other firms, as applicable, or to  specific funds or groups of funds  within
    or  outside of such peer group. Lipper generally ranks funds on the basis of
    total return,  assuming reinvestment  of distributions,  but does  not  take
    sales charges or redemption fees into consideration, and is prepared without
    regard  to tax  consequences. In addition  to the mutual  fund rankings, the
    Fund's performance  may  be  compared to  mutual  fund  performance  indices
    prepared  by Lipper. Morningstar  is a mutual fund  rating service that also
    rates mutual funds  on the basis  of risk-adjusted performance.  Morningstar
    ratings are calculated from a fund's three, five and ten year average annual
    returns  with appropriate  fee adjustments and  a risk  factor that reflects
    fund performance  relative to  the three-month  U.S. Treasury  bill  monthly
    returns.  Ten percent  of the funds  in an investment  category receive five
    stars and 22.5% receive four stars.  The ratings are subject to change  each
    month.
 
        (3)  Bear  Stearns Foreign  Bond  Index, which  provides  simple average
    returns for individual countries and gross national product ("GNP") weighted
    index, beginning in 1975.  The returns are broken  down by local market  and
    currency.
 
        (4)  Ibbotson  Associates  International Bond  Index,  which  provides a
    detailed breakdown of local market and currency returns since 1960.
 
        (5) Standard & Poor's 500 Composite Stock Price Index, which is a widely
    recognized index  composed of  the  capitalization-weighted average  of  the
    price of 500 of the largest publicly traded stocks in the United States.
 
        (6) Dow Jones Industrial Average.
 
        (7) CNBC/Financial News Composite Index.
 
        (8) Morgan Stanley Capital International World Indices, including, among
    others, the Morgan Stanley Capital International Europe, Australia, Far East
    Index  ("EAFE Index").  The EAFE  index is an  unmanaged index  of more than
    1,000 companies in Europe, Australia and the Far East.

information reported by the Federal Reserve and the respective central banks  of
various  nations. In addition,  GT Global may  use performance rankings, ratings
and  commentary  reported  periodically  in  national  financial   publications,
including  Money Magazine,  Mutual Fund  Magazine, Smart  Money, Global Finance,
EuroMoney, Financial World, Forbes, Fortune,  Business Week, Latin Finance,  the

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

From time  to  time,  the  Fund  and  GT Global  may  refer  to  the  number  of
shareholders  in the  Fund or  the aggregate  number of  shareholders in  all GT
Global Mutual Funds or the dollar  amount of the Fund's assets under  management
or rankings by DALBAR Surveys, Inc. in advertising materials.
 
GT  Global  believes  the  Fund  is  an  appropriate  investment  for  long-term
investment  goals  including  funding   retirement,  paying  for  education   or
purchasing  a  house.  GT  Global  may  provide  information  designed  to  help
individuals understand  their investment  goals  and explore  various  financial
strategies. For example, GT Global may describe general principles of investing,
such  as asset allocation, diversification and risk tolerance. The Fund does not
represent a complete investment program, and investors should consider the  Fund
as  appropriate for a portion of  their overall investment portfolio with regard
to their  long-term  investment goals.  There  is  no assurance  that  any  such
information will lead to achieving these goals or guarantee future results.
 
From  time to time,  GT Global may refer  to or advertise the  names of U.S. and
non-U.S. companies and their products, although  there can be no assurance  that
any GT Global Mutual Fund may own the securities of these companies.
 
Ibbotson  Associates of Chicago, Illinois (Ibbotson) provides historical returns
of the capital  markets in  the United  States, including  common stocks,  small
capitalization  stocks, long-term corporate  bonds, intermediate-term government
bonds, long-term government bonds,  Treasury bills, the  U.S. rate of  inflation
(based on the CPI), and combinations of various capital markets. The performance
of these capital markets are 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.
 
The Fund may quote various measures of volatility and benchmark correlation such
as  beta, standard  deviation and  R in advertising.  In addition,  the Fund may
compare these measures to those of  other funds. Measures of volatility seek  to
compare the Fund's historical share price fluctuations or total returns compared
to  those  of  a  benchmark.  All measures  of  volatility  and  correlation are
calculated using averages of historical data.
 
The Fund may  advertise examples of  the effects of  periodic investment  plans,
including the principle of dollar cost averaging programs. In such a program, an
investor  invests a fixed dollar amount in a fund at periodic intervals, thereby
purchasing fewer shares  when prices are  high and more  shares when prices  are
low.  While such a strategy does not assure  a profit or guard against loss in a
declining market, the  investor's average cost  per share can  be lower than  if
fixed  numbers of shares are purchased at the same intervals. In evaluating such
a plan, investors should  consider their ability  to continue purchasing  shares
through periods of low price levels.
 
The  Fund may describe in its sales  material and advertisements how an investor
may invest in GT Global Mutual  Funds through various retirement plans or  other
programs that offer deferral of income taxes on investment earnings and to which
an  investor  may make  deductible contributions.  Because of  their advantages,
these retirement plans and programs  may produce returns superior to  comparable
non-retirement  investments. For example, a $10,000 investment earning a taxable
return of 10% annually would have an after-tax value of $17,976 after ten years,
assuming tax  was  deducted from  the  return each  year  at a  39.6%  rate.  An
equivalent  tax-deferred  investment would  have an  after-tax value  of $19,626
after ten years, assuming  tax was deducted  at a 39.6%  rate from the  deferred
earnings   at  the   end  of  the   ten-year  period.  In   sales  material  and
advertisements, the  Fund  may  also  discuss  these  plans  and  programs.  See
"Information Relating to Sales and Redemptions -- Individual Retirement Accounts
("IRAs") and Other Tax-Deferred Plans."
 
GT  Global may from time to time  in its sales materials and advertising discuss
the risks inherent in investing. The  major types of investment risk are  market
risk,  industry  risk,  credit  risk, interest  rate  risk,  liquidity  risk and
inflation risk. Risk represents the possibility that you may lose some or all of
your investment over a period of time. A basic tenet of investing is the greater
the potential reward, the greater the risk.
 
From time to time, the Fund and GT Global will quote data regarding  industries,
companies,  individual countries,  regions, world stock  exchanges, and economic

From time  to  time,  GT Global  may  include  in its  advertisement  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 NEW DIMENSION FUND
 
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.
 
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.
 
GENERAL INFORMATION ABOUT THE UNDERLYING THEME PORTFOLIOS
Each  Underlying Theme Portfolio  may invest worldwide  across industries within
the Portfolio's area of concentration without national or regional restrictions.
The ability of each Underlying Theme Portfolio to invest worldwide may allow the
portfolio managers to select industries in different economic cycles and varying
stages of development, though  there is no assurance  that the managers will  be
successful in this selection.
 
Each  Underlying Theme Portfolio's area of concentration reflects the underlying
theme of  the Portfolio.  GT  Global believes  that  there are  certain  social,
political  and economic trends that may benefit one or more industries within an
Underlying Theme  Portfolio's area  of  concentration. Of  course, there  is  no
assurance that any of the Funds will benefit as a result.

INFORMATION ABOUT THE GLOBAL HEALTH CARE INDUSTRIES
The  Fund and  the Manager believe  that certain market  and demographic factors
merit  an  investor's  consideration  when  making  a  health  care  investment.
Worldwide   standards  of  living  and  life  expectancy  have  increased  at  a
substantial rate. Chancellor  LGT Asset  Management, Inc.  (the "Manager"),  the
investment  adviser to  the GT Global  Mutual Funds, expects  this growth, which
works to the general benefit of the global health care industry, to continue  at
a  roughly comparable rate in the future, although no assurances can be given in
this regard.  Moreover,  according to  the  Manager, the  health  care  industry
historically  has proven to be a relatively non-cyclical industry that continues
to provide goods and services to the  public in periods of economic weakness  as
well as economic strength.
 
The  Manager  believes  that the  anticipated  increase in  the  world's elderly
population could  increase demand  for health  care products  and services.  For
example,  according to  data compiled  by the  Manager, in  Japan the  number of
people age 65  and older  is expected to  grow over  100% by the  year 2025;  in
Germany, France and the U.S., the same age group should grow 40%. Similarly, the
U.S.  Census Bureau predicts the  number of Americans 85  and older to double in
the next  30 years.  From  time to  time,  the Fund  and  GT Global  will  quote
information   including,  but  not  limited  to,  international  data  regarding
populations,  birth  rates,  mortality  rates,  life  expectancy,  health   care
expenditures,  and gross domestic  product vs. life  expectancy. The information
quoted has not been independently verified by the Fund or GT Global and will  be
based on data that is believed to be reliable and accurate.

        countries around the world
 
    / / Supply and demand of telephone equipment and services
 
    / / Regulatory environment of telecommunications industries
 
    / / Revenue, price and usage of telecommunications products and services
 
    / / Privatization and/or deregulation of telecommunications companies

accurate from sources including the following:

        stock  market data about the  telecommunications industry in established
        and developing markets

        publishes  reports such as EASTERN EUROPEAN  & SOVIET TELECOM REPORT and
        LATIN AMERICAN TELECOM REPORT
 
    / / Telegeography and other publications
 
DEREGULATION IN THE UNITED STATES
The United States  has been  the bellwether  for deregulation  of the  telephone
industry.  The  divestiture  of  the Bell  System  from  American  Telephone and
Telegraph has  produced competing  companies  in the  United States.  Such  U.S.
market-driven  competition has,  for example, led  to lower  costs for consumers
which in turn led to greater consumer usage and to higher industrywide revenues.
The Manager expects this scenario to  continue to benefit such companies in  the
U.S. and

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
Moody's  employs the designations "Prime-1" and "Prime-2" to indicate commercial
paper having the highest  capacity for timely  repayment. Issuers rated  Prime-1
(or  supporting institutions)  have a superior  ability for  repayment of senior
short-term debt obligations. Prime-1 repayment  ability will often be  evidenced
by   many  of  the  following   characteristics:  leading  market  positions  in
well-established  industries;   high  rates   of  return   on  funds   employed;
conservative  capitalization structure with moderate  reliance on debt and ample
asset protection; broad margins in earnings coverage of fixed financial  charges
and  high internal  cash generation; and  well-established access to  a range of
financial markets  and assured  sources of  alternate liquidity.  Issuers  rated
Prime-2  (or supporting  institutions) 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 rates commercial paper in four categories ranging from "A-1" for the highest
quality obligations  to  "D"  for  the lowest.  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 payment on
issues with this designation  is satisfactory. However,  the relative degree  of
safety  is not as  high as for  issues designated "A-1."  A-3 -- Issues carrying
this designation have adequate capacity  for timely payment. They are,  however,
more  vulnerable  to  the  adverse  effects  of  changes  in  circumstances than
obligations carrying the higher designations. B -- Issues rated "B" are regarded
as having only  speculative capacity  for timely payment.  C --  This rating  is
assigned  to short-term debt obligations with a doubtful capacity for payment. D
- -- Debt rated "D" is  in payment default. The "D"  rating category is used  when
interest  payments or principal payments  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.
 
DESCRIPTION OF BOND RATINGS
Moody's  rates the  long-term debt  securities issued  by various  entities from
"Aaa" to "C." Investment Grade Ratings are the first four categories:
 
        Aaa --  Best quality.  These  securities 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  -- 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  --  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 sometime in the future.
 
        Baa -- 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 -- Have speculative elements and 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  --  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.

                          GT GLOBAL NEW DIMENSION FUND
 
        Caa -- Poor  standing. Such issues  may be  in default or  there may  be
    present elements of danger with respect to principal or interest.
 
        Ca  -- Speculative in a high degree. Such issues are often in default or
    have other marked shortcomings.
 
        C -- Lowest rated  class of bonds.  Issues so rated  can be regarded  as
    having  extremely  poor  prospects  of ever  attaining  any  real investment
    standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has  been
suspended  or withdrawn, it may  be for reasons unrelated  to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1.  An application for rating was not received or accepted.
 
    2.  The issue or issuer belongs  to a group of securities or companies  that
       are not rated as a matter of policy.
 
    3.  There is a lack of essential data pertaining to the issue or issuer.
 
    4.    The  issue was  privately  placed, in  which  case the  rating  is not
       published in Moody's publications.
 
Suspension or withdrawal may occur if new and material circumstances arise,  the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable  up-to-date data  to permit  a judgment  to be  formed; if  a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies  numerical modifiers  1, 2 and  3 in  each generic  rating
classification  from Aa to B in its corporate bond rating system. 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 issue ranks in the lower end of its generic rating category.
 
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 -- Highest rating. Capacity to  pay interest and repay principal  is
    extremely strong.
 
        AA  --  Very strong  capacity to  pay interest  and repay  principal and
    differs from the higher rated issues only in a small degree.
 
        A -- Has a strong capacity to pay interest and repay principal  although
    it  is  somewhat  more susceptible  to  the  adverse effects  of  changes in
    circumstances and economic conditions than debt in higher rated categories.
 
        BBB -- Regarded as  having adequate capacity to  pay interest and  repay
    principal.  Whereas  it  normally exhibits  adequate  protection parameters,
    adverse economic conditions  or changing  circumstances are  more likely  to
    lead  to a weakened capacity to pay interest and repay principal for debt in
    this category than in higher rated categories.
 
        BB, B, CCC,  CC, C  -- Debt  rated "BB," "B,"  "CCC," "CC,"  and "C"  is
    regarded,  on balance, as predominantly speculative with respect to capacity
    to pay interest  and repay  principal in accordance  with the  terms of  the
    obligation.  "BB" indicates  the lowest  degree of  speculation and  "C" the
    highest degree of speculation. While such debt will likely have some quality
    and protective characteristics, these are outweighed by large  uncertainties
    or major risk exposures to adverse conditions.
 
        BB -- Has less near-term vulnerability to default than other speculative
    issues. However, it faces major ongoing uncertainties or exposure to adverse
    business,  financial, or economic conditions  which could lead to inadequate
    capacity to meet  timely interest  and principal payments.  The "BB"  rating
    category  is also used for debt subordinated to senior debt that is assigned
    an actual or implied "BBB-" rating.
 
        B --  Has a  greater  vulnerability to  default  but currently  has  the
    capacity  to  meet  interest  payments  and  principal  repayments.  Adverse
    business, financial, or economic conditions  will likely impair capacity  or
    willingness  to pay interest and repay principal. The "B" rating category is
    also used for debt subordinated to senior debt that is assigned an actual or
    implied "BB" or "BB-" rating.
 
        CCC -- Has  a currently  identifiable vulnerability to  default, and  is
    dependent  upon favorable  business, financial,  and economic  conditions to
    meet timely payment of interest and repayment of principal. In the event  of
    adverse  business, financial,  or economic conditions,  it is  not likely to
    have the capacity  to pay  interest and  repay principal.  The "CCC"  rating
    category  is also used for debt subordinated to senior debt that is assigned
    an actual or implied "B" or "B-" rating.
 
                  Statement of Additional Information Page 47
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        CC -- Typically  applied to  debt subordinated  to senior  debt that  is
    assigned an actual or implied "CCC" rating.
 
        C  --  Typically applied  to debt  subordinated to  senior debt  that is
    assigned an actual or implied "CCC-" debt rating. The "C" rating may be used
    to cover a situation  where a bankruptcy petition  has been filed, but  debt
    service payments are continued.
 
        C1 -- Reserved for income bonds on which no interest is being paid.
 
        D -- In payment default. The "D" category is used when interest payments
    or  principal payments 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. This rating will also be used upon the filing
    of a bankruptcy petition if debt service payments 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.
