GT GLOBAL NEW DIMENSION FUND (the "Fund") is a diversified series of GT Global
Series Trust (the "Trust"), an open-end management investment company. The Fund
seeks long-term growth of capital. Unlike a typical mutual fund, which invests
directly in portfolio securities, the Fund invests primarily 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.

with the Securities and Exchange Commission ("SEC") and, as supplemented or
amended from time to time, is incorporated by reference. The Statement of

The following summary is qualified in its entirety by the more detailed
information appearing in the body of this Prospectus. Cross-references in the

Investment Objective:                             The Fund seeks long-term growth of capital.
                               The  Fund  seeks  its  investment objective  by  investing  in the
Principal Investments:         following  GT  Global  theme  mutual  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  among 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 newly
                               organized entity, the Fund has no operating history.
Investment Manager:            The Manager is part of  Liechtenstein Global Trust, a provider  of
                               global  asset management and private banking products and services

                               approximately $87 billion in total assets as of June 30, 1997. The

SUMMARY OF INVESTOR COSTS. The expenses and maximum transaction costs associated
with investing in the Class A and Class B shares of the Fund are reflected in
the following tables.

- ------------------
*   Sales charge waivers are available for Class A and Class B shares, and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase. The charge declines
    thereafter, reaching zero after six years. 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 shared 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 to certain
    categories of investors. See "Alternative Purchase Plan." Advisor Class
    shares are not subject to 12b-1 distribution and service fees.
 
In  addition to the Annual  Fund Operating Expenses shown  above, the Fund, as a
shareholder in the  Underlying Theme Funds,  will indirectly bear  its pro  rata
share  of the  fees and expenses  incurred by  the Underlying Theme  Funds. As a
result, the investment  returns of  the Fund will  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 the semi-annual period ended April 30, 1997.

(1) Effective November 1, 1997, the Manager will limit each Underlying Theme
    Fund's expenses to a maximum level of 1.50% of the average daily net assets
    of such Fund's Advisor Class shares. This undertaking by the Manager may be
    changed or eliminated at any time.
 
(2) Without reimbursement by the Manager, the expense ratio would have been
    2.35%.

    aggregate expense ratio will not exceed 2.00% and 2.50% for Class A and
    Class B Shares, respectively.
 
HYPOTHETICAL EXAMPLE OF EFFECT OF EXPENSES:
 
An investor would have directly or indirectly paid the following expenses of the
Fund and, by extension, of the Underlying Theme Funds at the end of the periods
shown on a $1,000 investment in the Fund, assuming a 5% annual return:

                           ALTERNATIVE PURCHASE PLAN
 
- --------------------------------------------------------------------------------
 
DIFFERENCES BETWEEN THE CLASSES. The primary difference between the two classes
of the Fund's shares offered through this Prospectus lies in their sales charge
structures and ongoing expenses, as summarized below. Class A and Class B shares
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, and each class has a separate
exchange privilege. See "Management" and "How to Make Exchanges." Each class has
distinct advantages and disadvantages for different investors, and investors
should choose the class that better suits their circumstances and objectives.
 
CLASS A SHARES. Class A shares are sold at net asset value plus an initial sales
charge of up to 4.75% of the public offering price imposed at the time of
purchase. This initial sales charge is reduced or waived for certain purchases.
Purchases of $500,000 or more must be for Class A shares. Class A shares also
bear annual 12b-1 service and distribution fees of up to 0.50% of the average
daily net assets of that class.
 
CLASS B SHARES. Class B shares are sold at net asset value with no initial sales
charge at the time of purchase. Therefore, the entire amount of an investor's
purchase payment is invested in the Fund. Class B shares bear annual service and
distribution fees of up to 1.00% of the average daily net assets of that class,
and Class B shareholders pay a contingent deferred sales charge of up to 5.00%
of the lesser of the original purchase price or the net asset value of such
shares at the time of redemption. The higher service and distribution fees paid
by the Class B shares should cause that class to have a higher expense ratio and
to pay lower dividends per share than Class A shares.
 
FACTORS TO CONSIDER IN CHOOSING A CLASS OF SHARES. In deciding which class of
shares of the Fund to purchase, investors should consider the foregoing factors
as well as the following:
 
INTENDED HOLDING PERIOD. Over time, the cumulative expense of the 1.00% service
and distribution fees on the Class B shares will approximate or exceed the
expense of the applicable 4.75% maximum initial sales charge plus the 0.50%
service and distribution fees on the Class A shares. For example, if net asset
value remains constant, the Class B shares' aggregate service and distribution
fees would be equal to the Class A shares' initial maximum sales charge and
service and distribution fees approximately nine years after purchase.
Thereafter, Class B shares would experience higher cumulative expenses.
Investors who expect to maintain their investment in the Fund over the long-term
but do not qualify for a reduced initial sales charge might elect the Class A
initial sales charge alternative because the indirect expense to the shareholder
of the accumulated service and distribution fees on the Class B shares
eventually will exceed the initial sales charge paid by the shareholder plus the
indirect expense to the shareholder of the accumulated service and distribution
fees of Class A shares. Investors in Class B shares, however, enjoy the benefit
of permitting all their dollars to work from the time an investment is made. Any
positive investment return on this additional invested amount would partially or
wholly offset the higher annual expenses borne by Class B shares. Because the
Fund's future returns cannot be predicted, however, there can be no assurance
that such a positive return will be achieved.
 
Finally, Class B shareholders pay a contingent deferred sales charge if they
redeem during the first six years after purchase, unless a sales charge waiver
applies. Investors expecting to redeem during this period should consider the
cost of the applicable contingent deferred sales charge in addition to the
annual Class B service and distribution fees, as compared with the cost of the
applicable initial sales charge and annual service and distribution fees
applicable to the Class A shares.
 
REDUCED SALES CHARGES. Class A share purchases of $50,000 or more and Class A
share purchases made under the Fund's reduced sales charge plans may be made at
a reduced initial sales charge. See "How to Invest" for a complete list of
reduced sales charges applicable to Class A share purchases.
 
WAIVER OF SALES CHARGES. The entire initial sales charge on Class A shares is
waived for certain eligible purchasers, and these purchasers' entire purchase
 
                               Prospectus Page 7
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
price would be immediately invested in the Fund. Investors eligible for complete
initial sales charge waivers should purchase Class A shares. The contingent
deferred sales charge is waived for certain redemptions of Class B shares. A 1%
contingent deferred sales charge is imposed on certain redemptions of Class A
shares on which no initial sales charge was assessed.
 
Investors should understand that the contingent deferred sales charge on the
Class B shares and the initial sales charge on the Class A shares are both
intended to compensate GT Global and selling broker/dealers for their
distribution services. Broker/dealers may receive different levels of
compensation for selling a particular class of shares of the Fund.
 
See "How to Invest," "How to Redeem Shares" and "Management" for a more complete
description of the initial and contingent deferred sales charges, service and
distribution fees for Class A and Class B shares and "Dividends, Other
Distributions and Federal Income Taxation" and "Calculation of Net Asset Value"
for other differences between these two classes.
 
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% on 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% on the assets in the account; (d) accounts advised by one of the
companies composing or affiliated with Liechtenstein Global Trust; and (e) any
of the companies composing or affiliated with Liechtenstein Global Trust.

                            INVESTMENT OBJECTIVE AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
 
The Fund seeks long-term growth of capital. Unlike a typical mutual fund, which
invests directly in portfolio securities, the Fund invests in shares of the GT
Global theme mutual funds. The Fund seeks its investment objective by investing,
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 Consumer Products and Services Fund, Financial Services Fund, Infrastructure
Fund and Natural Resources Fund, in turn, each seeks its investment objective by
investing all of its investable assets in the corresponding series of another
open-end investment company. See "Risk Factors and Special Considerations."
 
The Manager exercises no discretion in investing the Fund's assets. Rather, the
Manager periodically determines the allocation of assets to the Underlying Theme
Funds according to the industry weightings of the companies comprising the
Morgan Stanley Capital International All Country (AC) World Index ("MSCI"). (The
MSCI is a broad unmanaged index of global stock prices, currently comprising
approximately 2,500 different issuers, located in 47 countries comprising both
developed and developing countries. Each of the 2,500 stocks is placed into one
of 38 MSCI industry sectors.) The Manager assesses which of the Underlying Theme
Funds can invest, as part of their 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 comprise in the MSCI is then used by the
Manager
 
                               Prospectus Page 8
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
as the percentage of new money in the Fund that will be invested in 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 comprise 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 new money in each Underlying
Theme Fund according to the MSCI weighting as of the last business day of the
preceding month. As of August 29, 1997, the weight assigned to each Underlying
Theme Fund, using the above methodology, would have been as follows:
 
<TABLE>
<S>                                        <C>
Consumer Products and Services Fund......      30.3%
Financial Services Fund..................      20.7%
Health Care Fund.........................       9.2%
Infrastructure Fund......................      17.1%
Natural Resources Fund...................      13.4%
Telecommunications Fund..................       9.2%
</TABLE>
 
The Fund is a more diversified investment than would be achieved by investing in
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
newly organized entity, the Fund has no operating history.
 
OTHER INFORMATION. The investment objective of the Fund may not be changed
without the approval of a majority of its outstanding voting securities. As
defined in the Investment Company Act of 1940, as amended ("1940 Act"), and as
used in this Prospectus, a "majority of the Fund's outstanding voting
securities" means 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. In addition, the Fund has adopted
certain investment limitations as fundamental policies that also may not be
changed without shareholder approval. See "Investment Limitations" in the
Statement of Additional Information. Unless specifically noted, the Fund's
investment policies described in this Prospectus, and in the Statement of
Additional Information, are not fundamental policies and may be changed by vote
of the Trust's Board of Trustees without shareholder approval.

                                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 can be 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. Stock values fluctuate in
response to the activities of individual companies and economic conditions.
 
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.
Moreover, the value of the shares of each Underlying Theme Fund will be
especially susceptible to factors affecting the industries in which it focuses.
 
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
 
                               Prospectus Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
INVESTMENT PRACTICES OF THE UNDERLYING THEME FUNDS. In addition to their
principal investments, certain Underlying Theme Funds may enter into forward
currency transactions; lend their portfolio securities; enter into stock index,
interest rate and currency futures contracts, and options on such contracts;
engage in options transactions; purchase restricted and illiquid securities;
purchase securities on a when-issued or delayed delivery basis; enter into
repurchase or reverse repurchase agreements; borrow money and engage in various
other investment practices. See the following paragraphs and the Fund's
Statement of Additional Information.
 
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
 
                               Prospectus Page 12

                          GT GLOBAL NEW DIMENSION FUND
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; (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; and (7) through the end of
1997, the possible need to defer closing out certain options, futures contracts,
forward currency contracts and/or foreign currency positions in order to
continue to qualify for the beneficial tax treatment afforded regulated
investment companies under the Internal Revenue Code of 1986, as amended
("Code").
 
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.
 
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 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 37%
to 169% 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.
 
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.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
GENERAL. 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 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. The minimum initial investment is $500 ($100 for IRAs and $25 for
custodial accounts under Section 403(b)(7) of 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), and the minimum
for additional purchases is $100 ($25 for IRAs, Code Section 403 (b)(7)
custodial accounts and other tax-qualified employer-sponsored retirement
accounts, as mentioned above). THE FUND AND GT GLOBAL RESERVE THE RIGHT TO
REJECT ANY PURCHASE ORDER AND TO SUSPEND THE OFFERING OF SHARES FOR A PERIOD OF
TIME. In particular, the Fund and GT Global may reject purchase orders or
exchanges by investors who appear to follow, in the Manager's judgment, a
market-timing strategy or otherwise engage in excessive trading. See "How To
Make Exchanges -- Limitations on Purchase Orders and Exchanges."
 
WHEN PLACING PURCHASE ORDERS, INVESTORS SHOULD SPECIFY WHETHER THE ORDER IS FOR
CLASS A OR CLASS B SHARES OF THE FUND. ALL PURCHASE ORDERS THAT FAIL TO SPECIFY
A CLASS WILL AUTOMATICALLY BE INVESTED IN CLASS A SHARES. PURCHASES OF $500,000
OR MORE MUST BE FOR CLASS A SHARES.
 
PURCHASES THROUGH BROKER/DEALERS. Shares of the Fund may be purchased through
broker/dealers with which GT Global has entered into dealer agreements. Orders
received by such broker/dealers before the close of regular trading on the NYSE
on a Business Day will be effected that day, provided that such order is
transmitted to the Transfer Agent prior to its close of business on such day.
The broker/dealer will be responsible for forwarding the investor's order to the
Transfer Agent so that it will be received prior to such time. After an initial
investment is made and a shareholder account is established through a
broker/dealer, at the investor's option subsequent purchases may be made
directly through GT Global. See "Shareholder Account Manual."
 
Broker/dealers that do not have dealer agreements with GT Global also may offer
to place orders for the purchase of shares. Purchases made through such
broker/dealers will be effected at the public offering price next determined
after the order is
 
                               Prospectus Page 14
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
received by the Transfer Agent. Such a broker/ dealer may charge the investor a
transaction fee as determined by the broker/dealer. That fee will be in addition
to the sales charge payable by the investor, with respect to Class A shares, and
may be avoided if shares are purchased through a broker/ dealer that has a
dealer agreement with GT Global or directly through GT Global.
PURCHASES THROUGH GT GLOBAL. Investors may purchase shares and open an account
directly through GT Global, the Fund's distributor, 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.
 
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.
                           PURCHASING CLASS A SHARES
 
The Fund's public offering price for Class A shares is the next determined net
asset value per share (see "Calculation of Net Asset Value") plus a sales charge
determined in accordance with the following schedule:

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

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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-

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

trusts) other than a plan described in "(a)" above; and
 
(c) Individual purchases by a trustee or other fiduciary purchasing shares
concurrently for two or more employee benefit plans of a single employer or of
employers affiliated with each other (again excluding an employee benefit plan
described in "(a)" above).

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

which are sponsored by organizations 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.

(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 not eligible for the Advisor Class as to which a financial
institution or broker/dealer charges an account management fee, provided the

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 onetime 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. 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
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 shares purchased without a sales charge
may be exchanged for Class A shares of another GT Global

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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, on the amount realized on 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 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, 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 of the Fund may not be purchased for
a Savings Incentive Match Plan for Employees of Small Employers Individual
Retirement Accounts ("SIMPLE IRAs") for which a designated financial institution
was selected by the employer on Form 5305-SIMPLE. Class B shares of the Fund may
still be purchased for SIMPLE IRAs using Form 5304-SIMPLE. In addition, Class A
shares of the Fund may still 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.

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 of the Fund that are acquired as a result of an exchange of
shares of GT Global Floating Rate Fund ("Floating Rate Fund") will be subject,
in lieu of the contingent deferred sales charge described above, to a contingent
deferred sales charge equivalent to the early withdrawal charge on the common
stock of the Floating Rate

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Fund as set forth in the current prospectus of the Floating Rate Fund. The
purchase of 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, on the
amount realized on the redemption. See "Purchasing Class A Shares --
Reinstatement Privilege." The amount of any contingent deferred sales charge
will be paid to GT Global.

                              SALES CHARGE WAIVERS
 
The contingent deferred sales charge will be waived for (1) exchanges, as

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,

by applicable law from paying a sales charge or commission.
 
            PROGRAMS APPLICABLE TO CLASS A SHARES AND CLASS B SHARES
 
AUTOMATIC INVESTMENT PLAN. Investors may purchase either Class A or Class B
shares of the Fund through the GT Global Automatic Investment Plan. Under this
Plan, an amount specified by the shareholder of $100 or more ($25 or more for
IRAs, Code Section 403(b)(7) custodial accounts and other tax-qualified
employer-sponsored retirement accounts) on a monthly or quarterly basis will be
sent to the Transfer Agent from the investor's bank for investment in the Fund.
Participants in the Automatic Investment Plan should not elect to receive
dividends or other distributions from the Fund in cash. A sales charge will be
applied to each automatic monthly purchase of Class A 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 or Class B
shares of the Fund through the GT Global Dollar Cost Averaging Program whereby a
shareholder invests the same dollar amount each month. Accordingly, the investor
purchases more shares when the Fund's net asset value is relatively low and
fewer shares when the Fund's net asset value is relatively high. This can result
in a lower average cost-per-share than if the shareholder followed a less
systematic
 
                               Prospectus Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of GT Global Mutual Funds. The Program automatically
rebalances holdings of GT Global Mutual Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, GT Global Mutual Funds ("Personal Portfolio") is to
be rebalanced on a monthly, quarterly, semiannual, or annual basis.
 
Rebalancing under the Program will be effected through the exchange of shares of
one or more GT Global Mutual Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other GT Global Mutual Funds in the
shareholder's Personal Portfolio. See "How to Make Exchanges." If shares of the
GT Global Mutual Funds in a shareholder's Personal Portfolio have appreciated
during a rebalancing period, the Program will result in shares of GT Global
Mutual Fund(s) that have appreciated most during the period being exchanged for
shares of GT Global Mutual Fund(s) that have appreciated least. SUCH EXCHANGES
ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS
THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends, Other
Distributions and Federal Income Taxation." Participation in the Program does
not assure that a shareholder will profit from purchases under the Program, nor
does it prevent or lessen losses in a declining market.
 
The Program will automatically rebalance the shareholder's Personal Portfolio on
the 28th day of the last month of the period chosen (or the immediately
preceding business day if the 28th is not a business day), subject to any
limitations below. The Program will not execute an exchange if the variance in a
shareholder's Personal Portfolio for a particular Fund would be 2% or less. In
predesignating percentages, shareholders must use whole percentages and totals
must equal 100%. Shareholders participating in the Program may not request
issuance of physical certificates representing a Fund's shares. Exchanges made
under the Program are not subject to the four free exchanges per year
limitation. The Funds and GT Global reserve the right to modify, suspend, or
terminate the Program at any time on 60 days' prior written notice to
shareholders. A request to participate in the Program must be received in good
order at least five business days prior to the next rebalancing date. Once a
shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which Funds or
what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, Letter of Intent,
and Dollar Cost Averaging programs. Certain 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
 
- --------------------------------------------------------------------------------
 
Shares of the Fund may be exchanged for shares of the same class of any other GT
Global Mutual Fund based on their respective net asset values without imposition
of any sales charges, provided that the registration remains identical.
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'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 WORLDWIDE GROWTH FUND
   -- GT GLOBAL INTERNATIONAL GROWTH FUND
   -- GT GLOBAL EMERGING MARKETS FUND
   -- GT GLOBAL NEW PACIFIC GROWTH FUND
   -- GT GLOBAL EUROPE GROWTH FUND
   -- GT GLOBAL LATIN AMERICA GROWTH FUND
   -- GT GLOBAL AMERICA SMALL CAP GROWTH FUND
   -- GT GLOBAL AMERICA MID CAP GROWTH FUND
   -- GT GLOBAL AMERICA VALUE FUND
   -- GT GLOBAL JAPAN GROWTH FUND
   -- GT GLOBAL GROWTH & INCOME FUND
   -- GT GLOBAL GOVERNMENT INCOME FUND
   -- GT GLOBAL STRATEGIC INCOME FUND
   -- GT GLOBAL HIGH INCOME FUND
   -- GT GLOBAL DOLLAR FUND
   -- 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
   -- GT GLOBAL TELECOMMUNICATIONS 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 write or call 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 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
both Class A and Class B shares of the Fund, the Class A shares will be redeemed
first unless the shareholder specifically requests otherwise.
 
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 shares or, in
limited circumstances, Class A shares). 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 FOLLOWING ANY CHANGE OF THE SHAREHOLDER'S ADDRESS OF RECORD.

                          GT GLOBAL NEW DIMENSION FUND
 
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 or Class B
shares. No contingent deferred sales charge will be imposed on redemptions made
under the Systematic Withdrawal Plan. The minimum withdrawal amount is $100. The
amount or percentage a participating shareholder specifies to be redeemed may
not, on an annualized basis, exceed 12% of the value of the account, as of the
time the shareholder elects to participate in the Systematic Withdrawal Plan. To
participate in the Systematic Withdrawal Plan, investors should complete the
appropriate portion of the Supplemental Application provided at the end of this
Prospectus. Investors should contact their 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.
 
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 and dividends. The per share net
asset value of the Class B shares generally will be lower than that of the Class
A shares because of the higher service and distribution fees borne by the Class
B shares. The per share net asset value of the Advisor Class shares generally
will be higher than that of the Class A and Class B shares because of the
absence of any service and distribution fees applicable to the Advisor Class
shares. It is expected, however, that the net asset value per share of 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 between the classes.
 
- --------------------------------------------------------------------------------
 
                         DIVIDENDS, OTHER DISTRIBUTIONS
                          AND FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. The Fund annually declares and pays as a
dividend all of its net investment income, if any, which includes dividends 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 if necessary to avoid a 4%
excise tax on certain undistributed income and gain.
 
Dividends and other distributions paid by the Fund with respect to all classes
of its shares are calculated in the same manner and at the same time. The per
share income dividends on Class B shares will be lower than the per share income
dividends on Class A shares as a result of the higher service and distribution
fees applicable to Class B shares; and the per share income dividends on both
such classes of shares will be lower than the per share income dividends on the
Advisor Class shares 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 in shares of the
    corresponding class of other GT Global Mutual Funds); or
 
/ / to receive dividends in cash and have other distributions automatically
    reinvested in additional Fund shares of the distributing class (or in shares
    of the corresponding class of other GT Global Mutual Funds); or
 
                               Prospectus Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
/ / to receive other distributions in cash and have dividends automatically
    reinvested in additional Fund shares of the distributing class (or in shares
    of the corresponding class of other GT Global Mutual Funds); or
 
/ / to receive dividends and other distributions in cash.
 
Automatic reinvestments in additional shares are made at net asset value without
imposition of a sales charge. IF NO ELECTION IS MADE BY A SHAREHOLDER, ALL
DIVIDENDS AND OTHER DISTRIBUTIONS WILL BE AUTOMATICALLY REINVESTED IN ADDITIONAL
FUND SHARES OF THE DISTRIBUTING CLASS. Reinvestments in another GT Global Mutual
Fund may only be directed to an account with the identical shareholder
registration and account number. These elections may be changed by a shareholder
at any time; to be effective with respect to a distribution, the shareholder or
the shareholder's broker must contact the Transfer Agent by mail or telephone at
least 15 Business Days prior to the payment date. THE FEDERAL INCOME TAX
CONSEQUENCES OF DIVIDENDS AND OTHER DISTRIBUTIONS ARE THE SAME WHETHER THEY ARE
RECEIVED IN CASH OR REINVESTED IN ADDITIONAL SHARES.
 
Any dividend or other distribution paid by the Fund has the effect of reducing
the net asset value per share on the ex-distribution date by the amount thereof.
Therefore, a dividend or other distribution paid shortly after a purchase of
shares would represent, in substance, a return of capital to the shareholder (to
the extent the distribution is paid on the shares so purchased) even though
subject to income tax, as discussed below.
 
TAXES. The Fund intends to 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. The Taxpayer Relief Act of 1997 ("Act"), enacted in August
1997, dramatically changes the taxation of net capital gain, by applying
different rates thereto depending on the taxpayer's holding period and marginal
rate of federal income tax. The Act, however, does not address the application
of these rules to distributions by regulated investment companies and instead
authorizes the issuance of regulations to do so. Accordingly, shareholders
should consult their tax advisers as to the effect of the Act on distributions
by the Fund to them of net capital gain.
 
The Fund provides federal tax information to its shareholders annually,
including information about dividends and other distributions paid during the
preceding year.
 
The Fund must withhold 31% from dividends, capital gain distributions and
redemption proceeds payable to any individuals and certain other noncorporate
shareholders who have not furnished to the Fund a correct taxpayer
identification number or a properly completed claim for exemption on Form W-8 or
W-9. Withholding at that rate also is required from dividends and capital gain
distributions payable to such shareholders who otherwise are subject to backup
withholding. Fund accounts opened via a bank wire purchase (see "How to Invest
- -- Purchases Through the Distributor") are considered to have uncertified
taxpayer identification numbers unless a completed Form W-8 or W-9 or Account
Application is received by the Transfer Agent within seven days after the
purchase. A shareholder should contact the Transfer Agent if the shareholder is
uncertain whether a proper taxpayer identification number is on file with the
Fund.
 
A redemption of Fund shares may result in taxable gain or loss to the redeeming
shareholder, depending upon whether the redemption proceeds are more or less
than the shareholder's adjusted basis for the redeemed shares (which normally
includes any initial sales charge paid on Class A shares). An exchange of Fund
shares for shares of another GT Global Mutual Fund generally will have
 
                               Prospectus Page 26
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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,
formerly Bank in Liechtenstein, compose Liechtenstein Global Trust, formerly BIL
GT Group Limited. 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 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 June 30, 1997, the Manager and its worldwide affiliates managed
approximately $63 billion in assets. In the United States, as of June 30, 1997,
the Manager managed or administered approximately $9 billion of assets of the GT
Global Mutual Funds. As of June 30, 1997, assets entrusted to
 
                               Prospectus Page 27
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Liechtenstein Global Trust totaled approximately $87 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. Many of the GT Global Mutual Funds' portfolio managers are
natives of the countries in which they invest, speak local languages and/or live
or work in the markets they follow.
 
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 percentages of
its assets in each Underlying Theme Fund according to the total industry
weighting of the securities held by the Underlying Theme Funds as represented in
the MSCI.
 
DISTRIBUTION OF FUND SHARES. GT Global is the distributor of the Fund's Class A
and Class B shares. Like the Manager, GT Global is a subsidiary of Liechtenstein
Global Trust with offices at 50 California Street, 27th Floor, San Francisco, CA
94111. As distributor, GT Global collects the sales charges imposed on purchases
of Class A shares and any contingent deferred sales charges that may be imposed
on certain redemptions of Class A and Class B shares. GT Global reallows a
portion of the sales charge on Class A shares to broker/dealers that have sold
such shares in accordance with the schedule set forth above under "How to
Invest." In addition, GT Global pays a commission equal to 4.00% of the amount
invested to broker/dealers who sell Class B shares. A commission with respect to
Class B shares is not paid on exchanges or certain reinvestments in Class B
shares.
 
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 a separate plan of distribution adopted with respect to the Fund's
Class B shares ("Class B Plan"), the Fund may pay GT Global a service fee at the
annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class B shares for its expenditures incurred in servicing and maintaining
shareholder accounts, and may pay GT Global a distribution fee at the annualized
rate of up to 0.75% of the average daily net assets of the Fund's Class B shares
for its expenditures incurred in providing services as distributor. Expenses
incurred under the Class B Plan in excess of 1.00% annually may be carried
forward for reimbursement in subsequent years as long as 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
 
                               Prospectus Page 28
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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 incurred in connection with membership in investment company
organizations; 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; and the cost of printing and distributing reports and notices
to existing shareholders.
 
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 sought 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 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 aggregate financial benefits to the Underlying Theme Funds do not
exceed the expenses of the Fund, the Manager will pay that portion of the Fund's
expenses.
 
CONFIRMATIONS AND REPORTS TO SHAREHOLDERS. Each time a transaction is made that
affects a shareholder's account in the Fund, the shareholder will receive from
the Transfer Agent a confirmation statement reflecting the transaction.
Confirmations for transactions effected pursuant to the Fund's Automatic
Investment Plan, Systematic Withdrawal Plan and automatic dividend reinvestment
program may be provided quarterly. Shortly after the end of the Fund's fiscal
year on 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. Until such time as the Fund commences the public offering of
its shares, LGT Asset Management, Inc. will own 100% of the issued and
outstanding shares of the Fund and will be deemed to control the Fund under the
1940 Act.
 
If one or more additional series were established, on any matter submitted to a
vote of shareholders, shares of each series would be voted by its shareholders
individually when the matter affected the specific interest of that series only,
such as approval of its investment management arrangements. In addition, each
class of shares of the Fund has exclusive voting rights with respect to its
distribution plan. The shares of the 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
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 and Advisor
Class share of the Fund is equal in earnings, assets and voting privileges to
each other share in the Fund, except as noted above, and each class 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, California 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,
Massachusetts 02110, is custodian of the assets of the Fund.
 
COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts Avenue,
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, Massachusetts 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 no operating history as of the
date of this Prospectus and therefore no 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 the
maximum applicable sales charges and distribution and service fees. Returns
would be higher if these charges and fees were not reflected. The Fund invests
in the Advisor Class shares of the Underlying Theme Funds, which are not subject
to these 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") invest  all of their  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 on five
business days' notice. 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.

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
REPURCHASE  AGREEMENTS.  A repurchase  agreement is  a  transaction in  which an
Underlying Theme  Portfolio  purchases a  security  from a  bank  or  recognized
securities dealer and simultaneously commits to resell that security 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  security.  Although  repurchase agreements  carry  certain  risks not
associated with direct investments in securities, including possible decline  in
the  market  value of  the underlying  securities  and delays  and costs  to the
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.  In  the event  that  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 a  security to another party, such as  a
bank or broker/dealer, in return for cash, and agrees to repurchase the security
in  the future at  an agreed upon  price, which includes  an interest component.
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)  is
authorized  to 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
 
                   Statement of Additional Information Page 5
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
offset  potential  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.
An Underlying Theme  Portfolio may make  short sales "against  the box"  without
respect to such limitations. In this type of short sale, at the time of the sale
the  Underlying Theme Portfolio owns  the security it has  sold short or has the
immediate and unconditional right to acquire at no additional cost the identical
security.

                         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
 
                   Statement of Additional Information Page 6
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
    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 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
 
                   Statement of Additional Information Page 7
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
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. For example, a put  option may be purchased in order
to protect unrealized appreciation  of a security or  currency when the  Manager
deems  it desirable to continue to hold  the security or currency because of tax
considerations. 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
 
                   Statement of Additional Information Page 8
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 in order to  protect unrealized gains on  call
options  previously written  by it.  A call option  could be  purchased for this
purpose where  tax considerations  make  it inadvisable  to realize  such  gains
through  a closing purchase  transaction. Call options may  also be purchased at
times to  avoid  realizing  losses that  would  result  in a  reduction  of  the
Underlying  Theme Portfolio's 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 such
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.
 
                   Statement of Additional Information Page 9
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
The  staff 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 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
 
                  Statement of Additional Information Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 has purchased 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; that is, Futures Contracts  will be sold to protect against  a
decline  in  the price  of securities  or currencies  that the  Underlying Theme
Portfolio owns, or Futures Contracts will be purchased to protect the 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
 
                  Statement of Additional Information Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
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
 
                  Statement of Additional Information Page 12
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
the option is a call and a short position if the option is a put) at a specified
exercise price at any time during the period of the option. Upon exercise of the
option, the delivery of the Futures position by the writer of the option to  the
holder  of the option will be accompanied by delivery of the accumulated balance
in the writer's Futures margin account, which represents the amount by which the
market price of the  Futures Contract, at  exercise, exceeds (in  the case of  a
call) or is less than (in the case of a put) the exercise price of the option on
the Futures Contract. If an option is exercised on the last trading day prior to
the  expiration date of the option, the settlement will be made entirely in cash
equal to the difference between the exercise price of the option and the closing
level of the securities, currencies or index upon which the Futures Contract  is
based  on the expiration date. Purchasers of  options who fail to exercise their
options prior to the exercise date suffer a loss of the premium paid.
 
The purchase of  call options  on Futures  can serve as  a long  hedge, and  the
purchase  of put  options on Futures  can serve  as a short  hedge. Writing call
options on Futures can serve as a  limited short hedge, and writing put  options
on  Futures can serve as a limited long  hedge, using a strategy similar to that
used for writing options on securities, foreign currencies or indices.
 
If 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 CURRENCY CONTRACTS
A Forward Currency 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 Currency 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
 
                  Statement of Additional Information Page 13
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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-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,  if  its contra  party  agrees,  entering into  a  second contract
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.
 
                  Statement of Additional Information Page 14
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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 that an Underlying Theme Portfolio has purchased) 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,
 
                  Statement of Additional Information Page 15

                          GT GLOBAL NEW DIMENSION FUND
lower quality debt securities tend to  be more sensitive to economic  conditions
and  generally have more volatile prices than higher quality securities. Issuers
of lower  quality  securities  are  often highly  leveraged  and  may  not  have
available  to them more traditional methods of financing. For example, during an
economic downturn  or  a  sustained  period of  rising  interest  rates,  highly
leveraged  issuers of lower quality  securities may experience financial stress.
During such periods, such issuers may not have sufficient revenues to meet their
interest  payment  obligations.  The  issuer's  ability  to  service  its   debt
obligations  may also be  adversely affected by  specific developments affecting
the issuer, such as the issuer's  inability to meet specific projected  business
forecasts or the unavailability of additional financing. The risk of loss due to
default  by the issuer is significantly greater for the holders of lower quality
securities  because  such  securities  are   generally  unsecured  and  may   be
subordinated to the claims of other creditors of the issuer.
 
Lower  quality  debt securities  of corporate  issuers  frequently have  call or
buy-back features 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-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
 
                  Statement of Additional Information Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
not reflect its  financial position  or results of  operations in  the way  they
would  be reflected  had such financial  statements been  prepared in accordance
with U.S. generally accepted accounting principles. Most of the securities  held
by  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 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.

                          GT GLOBAL NEW DIMENSION FUND
 
    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.
 
    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, some Underlying Theme Portfolios intend to 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 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.

INVESTMENT LIMITATIONS OF THE FUND
 
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
("Required Vote").
 
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. However, each Underlying
Theme Portfolio will not concentrate  more than 25% of  its total assets in  any
one  industry. 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;
 
                  Statement of Additional Information Page 21

                          GT GLOBAL NEW DIMENSION FUND
 
        (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;
 
        (4)  engage in short  sales of securities or  maintain a short position,
    except that the Fund may (a) sell  short "against the box" and (b)  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.
 
Each Portfolio may not:
 
        (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;
 
                  Statement of Additional Information Page 22
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (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;
 
        (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 the 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" portfolio 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  Infrastructure Portfolio's  and
    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
a Required Vote.
 
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
    or for which  no readily  available market  exists, which  for this  purpose
    includes repurchase agreements maturing in more than seven days;
 
        (2)  Invest  in  companies  for the  purpose  of  exercising  control or
    management;
 
        (3) Purchase or sell real estate; provided that the Health Care Fund may
    invest in securities secured by real  estate or interests therein or  issued
    by companies that invest in real estate or interests therein;
 
        (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.

The  Telecommunications Fund has adopted the following investment limitations as
fundamental policies, which (unless otherwise noted) may not be changed  without
a Required Vote.
 
The Telecommunications Fund may not:
 
        (1)   Buy   or  sell   real  estate   (including  real   estate  limited
    partnerships); however,  the  Telecommunications  Fund may  invest  in  debt
    securities  secured  by  real  estate  or  interests  therein  or  issued by
    companies which invest in real  estate or interests therein, including  real
    estate investment trusts;
 
                  Statement of Additional Information Page 24

                          GT GLOBAL NEW DIMENSION FUND
 
        (2) Purchase or sell commodities or commodity contracts, except that the
    Telecommunications Fund 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)  Engage in the business of underwriting 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  the Telecommunications  Fund may purchase
    debt securities and enter into repurchase  agreements and may make loans  of
    portfolio securities;
 
        (5)  Purchase securities on margin, provided that the Telecommunications
    Fund may  obtain  such  short-term  credits as  may  be  necessary  for  the

    margin deposits in connection with futures contracts;
 
        (6) Borrow money except from banks not in excess of 33 1/3% of the value
    of  the  Telecommunications  Fund's  total  assets,  including  the   amount
    borrowed,  less all liabilities and indebtedness (other than the borrowing).
    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,
    futures  contracts,  options  on  futures  contracts  and  forward  currency
    contracts, as described in the  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,  the Telecommunications  Fund
    may invest in the securities of companies that engage in these activities.
 
In addition, the Telecommunications 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.
 
The  following  operating  policies  of  the  Telecommunications  Fund  are  not
fundamental policies  and may  be changed  by  vote of  the Company's  Board  of
Directors without shareholder approval.
 
The Telecommunications Fund may not:
 
        (1)  Invest in securities of an issuer if the investment would cause the
    Telecommunications Fund 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;

    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  Directors  of  the  Company,  the  Telecommunications  Fund'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 Telecommunications  Fund's portfolio,
    after taking into account  unrealized profits and  unrealized losses on  any
    contracts the Telecommunications Fund has entered into; or
 
                  Statement of Additional Information Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (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
    Fund's  total assets. While  borrowings exceed 5%  of the Telecommunications
    Fund's  total  assets,  the  Telecommunications  Fund  will  not  make   any
    additional investments.
 
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.

                          GT GLOBAL NEW DIMENSION FUND
 
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.
 
PORTFOLIO TRADING AND TURNOVER
The Fund's portfolio turnover rate  is expected to be  low, since the Fund  will
only  periodically rebalance its portfolio. The Fund's annual portfolio turnover
rate is not expected to exceed 20% annually.
 
The portfolio turnover rates of the Underlying Theme Portfolios have ranged from
37% to 169% during  their most recent  fiscal years. There  can be no  assurance
that the portfolio turnover rates of the Underlying Theme Portfolios will remain
within  this  range during  subsequent fiscal  years. Higher  portfolio turnover
rates may  result in  higher expenses  being incurred  by the  Underlying  Theme
Portfolios.

The Board of Trustees  has a Nominating and  Audit Committee, comprised of  Miss
Quigley  and Messrs.  Anderson, Bayley and  Patterson, which  is responsible for
nominating persons to serve as Trustees,  reviewing audits of the Trust and  its

of the Trustees and officers of the Trust is also a Director and Officer of G.T.
Investment Portfolios, Inc., G.T. Investment Funds, Inc., G.T. Global Developing
Markets  Fund, Inc. and G.T. Global Floating  Rate Fund, Inc., and a Trustee and

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
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 and  Class B  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 and Class B shares  of the Fund in accordance
with Rule 12b-1 under the  1940 Act (each a "Class  A Plan" and "Class B  Plan,"
respectively, and collectively, "Plans"). The rate of payments by 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 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.

- --------------------------------------------------------------------------------
 
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 or Class B 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, other than by wire  transfer, must be made by check or
money order drawn on a U.S. bank. Checks or money orders must be payable in U.S.
dollars.
 
As a condition of this offering, if an order to purchase either class of  shares
is  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 SHARES AND CLASS B SHARES
To establish  participation in  the Fund's  Automatic Investment  Plan  ("AIP"),
investors  or their broker/dealers should specify  whether investment will be in
Class A shares or Class B shares and 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.
 
INDIVIDUAL RETIREMENT ACCOUNTS (IRAS)
Class A  or Class  B shares  of  the Fund  may be  purchased as  the  underlying
investment for an IRA meeting the requirements of section 408(a) of the Internal
Revenue  Code of 1986,  as amended (the "Code").  IRA applications are available
from brokers or GT Global.
 
EXCHANGES
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. 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 or  Class B  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.
 
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  realized  long-term  or
short-term capital gains or losses. The SWP may be terminated at any time by the
Transfer Agent or the Fund upon thirty days' written notice or by a  shareholder
upon  written notice to the Fund or its 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  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  ("Income
Requirement");  (2) the Fund must  derive less than 30%  of its gross income for
its taxable year ending December 31, 1997, from the sale or other disposition of
securities held for less  than three months  ("Short-Short Limitation"); (3)  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 (4) 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
 
                  Statement of Additional Information Page 33

                          GT GLOBAL NEW DIMENSION FUND
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.
 
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  in, and  payable to
shareholders of record as  of a date  in, October, November  or December of  any
year  will  be  deemed  to have  been  paid  by  the Fund  and  received  by the
shareholders on December 31 of  that year if the  distributions are paid by  the
Fund  during  the following  January. Accordingly,  those distributions  will be
taxed to shareholders for the year in which that December 31 falls.
 
A portion of  the dividends from  the Fund's investment  company taxable  income
(whether  paid in cash or  reinvested in additional shares)  may be eligible for
the dividends-received deduction allowed  to corporations. The eligible  portion
may  not exceed  the 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 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  if a  dividend  paid  by the  Fund  to  a foreign
shareholder is  "effectively connected  with  the conduct  of  a U.S.  trade  or
business,"  in which case the  reporting and withholding requirements applicable
to domestic shareholders will apply. 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 nonresident
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  exemptive application pending with the Securities
and Exchange Commission  and a private  letter ruling request  pending 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. In  the  event  that  the aggregate
financial benefits to the Underlying Theme Funds do not exceed the costs of  the
Fund, the Manager will pay, on behalf of the Fund, that portion of costs, as set
forth herein, determined to be greater than the benefits.
 
Rule 12b-1 distribution and service fees will not be paid in accordance with the
Service Agreement. In addition, certain non-recurring and extraordinary expenses
will  not be paid in  accordance with the Service  Agreement 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  earnings, failure  to qualify  under subchapter  M of  the Internal Revenue
Code, or failure to timely file any required tax returns or other filings.

The audited financial  statements of  the Trust  included in  this Statement  of
Additional Information have been examined by Coopers & Lybrand L.L.P., as stated

company.
 
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 and Class B shares of the Fund, as follows: Standardized
Return (average  annual total  return ("T"))  is computed  by using  the  ending
redeeming  value ("ERV")  of a hypothetical  initial investment  of $1,000 ("P")
over a period of years ("n") according  to the following formula as required  by
the  SEC:  P(1+T)  =  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 and  Class B shares  of the Fund  and may  be
calculated according to several different formulas. Non-Standardized Returns may
be  quoted for the same or different time periods for which Standardized Returns
are quoted. Non-Standardized  Returns may  or may  not take  sales charges  into
account;  performance data calculated without taking the effect of sales charges
into account will be higher than data including the effect of such charges.
 
Average annual Non-Standardized  Return ("T")  is computed by  using the  ending
redeeming  value ("ERV")  of a hypothetical  initial investment  of $1,000 ("P")
over a period of years ("n") according  to the following formula as required  by
the  SEC:  P(1+T)  =  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 MARKET
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.

    ("MSCI").  The  MSCI is  a broad,  unmanaged index  of global  stock prices,
    currently comprising 2500  different issuers, located  in 47 countries,  and
    grouped in 38 separate industries.
 
       (10)  Salomon Brothers World  Government Bond Index  and Salomon Brothers
    World Government Bond Index-Non-U.S., each of  which is a widely used  index
    composed of world government bonds.

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

                          GT GLOBAL NEW DIMENSION FUND
 
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  be available  for  purchase  through retirement  plans  or other
programs offering deferral of or exemption from income taxes, which may  produce
superior  after-tax returns over time. 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.
 
The Fund may describe in its  sales material and advertisements how an  investor
may invest in GT Global Mutual Funds through various retirement plans that offer
deferral  of income taxes on investment earnings and may also enable an investor
to make deductible contributions. Because of their advantages, these  retirement
accounts  and plans  may produce  returns superior  to comparable non-retirement
investments. In sales  material and  advertisements, the Fund  may also  discuss
these accounts and plans, which include:
 
INDIVIDUAL RETIREMENT ACCOUNTS (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. Effective for taxable  years beginning after  1997, 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.
 
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-type  plans or  Code Section 401(k)  plans, but  with fewer administrative
requirements and therefore potential 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.
 
                  Statement of Additional Information Page 39
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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  RETIREMENT 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.
 
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,  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.

                          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 alrger 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.
 
                  Statement of Additional Information Page 42
<PAGE>
                          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 43
<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.

assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. Our procedures included
confirmation of cash held by the custodian as of August 18, 1997. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
In our opinion, the financial statement referred to above presents fairly, in
all material respects, the financial position of the Fund as of August 18, 1997,
