- --------------------------------------------------------------------------------
 
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.
 
Shares offered by this Prospectus are available for purchase only by certain
investors and are offered at net asset value without the imposition of a front-
end or contingent deferred sales charge or Rule 12b-1 fees.
 
This Prospectus sets forth concisely the information an investor should know
before investing and should be read carefully and retained for future reference.
A Statement of Additional Information, dated September 10, 1997, has been filed
with the Securities and Exchange Commission ("SEC") and, as supplemented or
amended from time to time, is incorporated by reference. The Statement of
Additional Information is available without charge by writing to the Fund at 50

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

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
                               to  individual   and  institutional   investors,  entrusted   with
                               approximately $87 billion in total assets as of June 30, 1997. The
                               Manager  and  its worldwide  asset management  affiliates maintain
                               investment offices in Frankfurt, Hong Kong, London, New York,  San
                               Francisco, Singapore, Sydney, Tokyo and Toronto. See "Management."

                                                                                            -------
</TABLE>
 
- ------------------
*   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." Investors purchasing Advisor Class shares through
    financial planners, trust companies, bank trust departments or registered
    investment advisers, or under a "wrap fee" program, will be subject to
    additional fees charged by such entities or by the sponsors of such
    programs. Where any account advised by one of the companies composing or
    affiliated with Liechtenstein Global Trust invests in Advisor Class shares
    of the Fund, such account shall not be subject to duplicative advisory 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%.

- --------------------------------------------------------------------------------
 
The  following table  shows the  estimated aggregate  expense ratio  of the Fund
based on a weighted average of the expense ratios of the Advisor Class shares of
the Underlying Theme Funds in which the Fund would have invested as of July  30,
1997,  plus the  Fund's expense  ratio. For  this purpose  (as set  forth in the
preceding table) the expense  ratios of the Underlying  Theme Funds are for  the
semi-annual period ended April 30, 1997.

Advisor Class.............................................................................               1.58%

- ------------------
(1) Because of the Manager's undertaking to limit each Underlying Theme Fund's
    expenses as described above, effective November 1, 1997, the Fund's
    aggregate expense ratio will not exceed 1.50% for Advisor Class shares.
 
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:

                            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 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 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
 
                               Prospectus Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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
 
                               Prospectus Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 Fund's prospectus and statement of additional
information.

trustees or other fiduciaries purchasing shares for employee benefit plans which
are sponsored by organizations which 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 such 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 ("Advisory Account"); (c) any account with assets of
at least $10,000 if (i) such account is established under a "wrap fee" program,
and (ii) the account holder pays the sponsor of such program an annual fee of at
least .50% on the assets in the account ("Wrap Fee 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. Financial planners, trust companies, bank trust
companies and registered investment advisers referenced in subpart (b) and

referred to as "Financial Advisors." Investors in Wrap Fee Accounts and Advisory
Accounts may only purchase Advisor Class shares through Financial Advisors who
have entered into agreements with GT Global or certain of its affiliates.
Investors may be charged a fee by their agents or brokers if they effect
transactions other than through a dealer.
 
All purchase orders will be executed at the public offering price next
determined after the purchase order is received. Orders received by GT Global
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 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."
 
Fiduciaries and Financial Advisors may be required to provide information
satisfactory to GT Global concerning their eligibility to purchase Advisor Class
shares. For specific information on opening an account, please contract your
Financial Advisor or GT Global.
 
PURCHASES BY BANK WIRE. Shares of the Fund may also be purchased 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. Prior telephonic or facsimile notice must be provided
to the Transfer Agent that a bank wire is being sent. A 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. For more information, please refer to the Shareholder
Account Manual in this Prospectus.
 
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.
 
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
 
                               Prospectus Page 13
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 of one or more other GT Global Mutual Funds in the
shareholder's Personal Portfolio. See "How to Make Exchanges." If shares of the
GT Global Mutual Fund(s) in a shareholder's Personal Portfolio have appreciated
during a rebalancing period, the Program will result in shares of GT Global
Mutual Fund(s) that have appreciated most during the period being exchanged for
shares of GT Global Mutual Fund(s) that have appreciated least. SUCH EXCHANGES
ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS
THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends, Other
Distributions and Federal Income Taxation." Participation in the Program does
not assure that a shareholder will profit from purchases under the Program, nor
does it prevent or lessen losses in a declining market.
 
The Program will automatically rebalance the shareholder's Personal Portfolio on
the 28th day of the last month of the period chosen (or the immediately
preceding business day if the 28th is not a business day), subject to any
limitations below. The Program will not execute an exchange if the variance in a
shareholder's Personal Portfolio for a particular Fund would be 2% or less. In
predesignating percentages, shareholders must use whole percentages and totals
must equal 100%. Shareholders participating in the Program may not request
issuance of physical certificates representing a Fund's shares. Exchanges made
under the Program are not subject to the four free exchanges per year
limitation. The Fund 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. 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.

- --------------------------------------------------------------------------------
 
Adviser Class shares of the Fund may be exchanged for Advisor Class shares of
any other GT Global Mutual Fund based on their respective net asset values,
provided that the registration remains identical. EXCHANGES ARE NOT TAX-FREE AND
MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR
FEDERAL INCOME TAX PURPOSES. See "Dividends, other Distributions and Federal
Income Taxation." In addition to the Fund, the GT Global Mutual Funds currently
include:
 
   -- GT GLOBAL WORLDWIDE GROWTH FUND
   -- GT GLOBAL INTERNATIONAL GROWTH FUND
   -- GT GLOBAL EMERGING MARKETS FUND

Up to four exchanges each year may be made without charge. A $7.50 service
charge will be imposed on each subsequent exchange. 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.
 
EXCHANGES BY TELEPHONE. A shareholder may give exchange information to his or
her Financial Advisor. 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.
 
Investors in Wrap Fee Accounts and Advisory Accounts interested in making an
exchange should contact their Financial Advisors to request the prospectus of
the other GT Global Mutual Fund(s) being considered. Other investors should
contact GT Global. See the Shareholder Account Manual in this Prospectus for
additional information.
 
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 and redemption proceeds
will be sent within seven days of the execution of a redemption request. Fund
shares may be redeemed at their net asset value and redemption proceeds will be
sent within seven days of the execution of a redemption request. 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. 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.
 
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.
 
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.
 
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

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
accompanied by properly endorsed share certificates.
 
OTHER IMPORTANT REDEMPTION INFORMATION. A request for redemption will not be
processed until all of the necessary documentation has been received in good
order. A shareholder in doubt as to what documents are required should contact
his or her Financial Advisor.
 
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.
 
GT reserves the right to redeem the shares of any Advisory Account or Wrap Fee
Account if the amount invested in GT Global Mutual Funds through such account is
reduced to less than $500 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 the amount invested in GT Global Mutual Funds through such account
to an aggregate amount of $500 or more.
 
For additional information on how to redeem shares, see the Shareholder Account
Manual in this Prospectus, or contact your Financial Advisor.

                          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 its 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 the Underlying Theme Funds, which are valued 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.
 
- --------------------------------------------------------------------------------
 
                         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 Advisor Class shares will be higher than the per share
income dividends on shares of other classes of the Fund as a result of the
service and distribution fees applicable to those other shares. SHAREHOLDERS MAY
ELECT:
 
/ / to have all dividends and other distributions automatically reinvested in
    additional Advisor Class shares of the Fund (or other GT Global Mutual
    Funds); or
 
/ / to receive dividends in cash and have other distributions automatically
    reinvested in additional Advisor Class shares of the Fund (or other GT
    Global Mutual Funds); or
 
/ / to receive other distributions in cash and have dividends automatically
    reinvested in additional Advisor Class shares of the Fund (or other GT
    Global Mutual Funds); or
 
/ / to receive dividends and other distributions in cash.
 
Automatic reinvestments in additional Advisor Class 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 ADVISOR CLASS SHARES OF THE FUND. 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.
 
                               Prospectus Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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. An exchange of
Fund shares for shares of another GT Global Mutual Fund generally will have
similar tax consequences. In addition, if Fund shares are purchased within 30
days before or after redeeming other Fund shares 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 imposed on Class A and Class B shares 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 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 Advisor
Class 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.

                          GT GLOBAL NEW DIMENSION FUND
 
GT Global, at its own expense, may provide 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.
 
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

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 imposed on Class A and Class B shares
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 imposed on Class A
and Class B shares 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.

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.
 
The Fund offers Advisor Class shares through this Prospectus to certain
investors. The Fund also offers Class A and Class B shares to investors through
a separate prospectus. Each class of shares will experience different net asset
values and dividends as a result of different expenses borne by each class of
shares. The per share net asset value and dividends of the Advisor Class shares
of the Fund generally will be higher than that of the Class A and Class B shares
of the Fund because of the higher expenses borne by the Class A and Class B
shares. Consequently, during comparable periods, the Fund expects that the total
return on an investment in shares of the Advisor Class will be higher than the
total return on Class A or Class B shares.
 
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.

toll-free at (800) 223-2138 or by writing to the Fund at 50 California Street,

                                  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.

                            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 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 an 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 an  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 portfolio  securities, as with  other extensions of
secured credit, consist of possible delays in receiving additional collateral or
in recovery of  the securities  and possible loss  of rights  in the  collateral
should the borrower fail financially.
 
COMMERCIAL   BANK  OBLIGATIONS.  For  the  purposes  of  each  Underlying  Theme
Portfolio's investment policies with respect to bank obligations, obligations of
foreign branches  of U.S.  banks and  of foreign  banks are  obligations of  the
issuing bank and may be general obligations of the parent bank. Such obligations
may, however, be limited by the terms of a specific obligation and by government
regulation.  As with investments in  non-U.S. securities in general, investments
in the obligations of foreign  branches of U.S. banks  and of foreign banks  may
subject  each Underlying Theme Portfolio to  investment risks that are different
in some  respects from  those of  investments in  obligations of  U.S.  issuers.
Although  each  Underlying Theme  Portfolio  will typically  acquire obligations
issued and supported by the credit of U.S. or foreign banks having total  assets
at  the time of purchase of $1 billion or more, this $1 billion figure is not an
investment policy or  restriction of  each Underlying Theme  Portfolio. For  the
purposes  of calculation with respect to the  $1 billion figure, the assets of a
bank will be deemed to include the assets of its U.S. and non-U.S. branches.
 
REPURCHASE AGREEMENTS.  A repurchase  agreement  is a  transaction in  which  an
Underlying  Theme  Portfolio  purchases a  security  from a  bank  or recognized
securities dealer and simultaneously commits to resell that security to the bank
or
 
                   Statement of Additional Information Page 4
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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.
 
                   Statement of Additional Information Page 5
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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.

                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use by  the Underlying Theme  Portfolios of options,  futures contracts and
forward currency contracts ("Forward Contracts") involves special considerations
and risks, as described  below. Risks pertaining  to particular instruments  are
described in the sections that follow.
 
        (1)  Successful  use  of  most of  these  instruments  depends  upon the
    Manager's ability  to  predict  movements  of  the  overall  securities  and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Manager is experienced in the
    use  of these  instruments, there  can be  no assurance  that any particular
    strategy adopted will succeed.
 
        (2) There  might  be  imperfect correlation,  or  even  no  correlation,
    between  price  movements  of  an  instrument  and  price  movements  of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge  increased by less  than the  decline in value  of the  hedged
    investment,  the  hedge  would  not  be fully  successful.  Such  a  lack of
    correlation might  occur  due to  factors  unrelated  to the  value  of  the
    investments  being hedged,  such as  speculative or  other pressures  on the
    markets in  which the  hedging instrument  is traded.  The effectiveness  of
    hedges  using hedging  instruments on indices  will depend on  the degree of
    correlation between price movements in the index and price movements in  the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or  partially offsetting the negative  effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by  offsetting the positive  effect of favorable  price
    movements  in the  hedged investments. For  example, if  an Underlying Theme
    Portfolio entered into a short hedge because the Manager projected a decline
    in the price of  a security in the  Underlying Theme Portfolio's  portfolio,
    and  the  price  of that  security  increased  instead, the  gain  from that
    increase might be wholly or  partially offset by a  decline in the price  of
    the hedging instrument. Moreover, if
 
                   Statement of Additional Information Page 6
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
    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, deemed to  be
attractive investments for the Underlying Theme Portfolios.
 
A  call option  gives the  holder (buyer)  the right  to purchase  a security or
currency at a specified price (the  exercise price) at any time until  (American
style)  or on (European style) a certain  date (the expiration date). So long as
the obligation  of the  writer of  a call  option continues,  he or  she may  be
assigned  an exercise  notice, requiring  him or  her to  deliver the underlying
security or  currency against  payment of  the exercise  price. This  obligation
terminates upon the expiration of the call option, or such earlier time at which
the  writer  effects  a closing  purchase  transaction by  purchasing  an option
identical to that previously sold.
 
Portfolio securities or currencies on which call options may be written will  be
purchased  solely on the basis of investment considerations consistent with each
Underlying Theme Portfolio's investment objective.  When writing a call  option,
an  Underlying  Theme  Portfolio,  in  return  for  the  premium,  gives  up the
opportunity for  profit from  a price  increase in  the underlying  security  or
currency above the exercise price, and retains the risk of loss should the price
of  the  security  or  currency  decline.  Unlike  one  who  owns  securities or
currencies not  subject to  an  option, an  Underlying  Theme Portfolio  has  no
control  over  when it  may be  required  to sell  the underlying  securities or
currencies, since  most  options may  be  exercised at  any  time prior  to  the
option's  expiration. If  a call option  that an Underlying  Theme Portfolio has
written expires, it will realize a gain  in the amount of the premium;  however,
such  gain may  be offset  by a decline  in the  market value  of the underlying
security or currency during the option period. If the call option is  exercised,
the  Underlying Theme Portfolio will realize a gain or loss from the sale of the
underlying security  or currency,  which  will be  increased  or offset  by  the
premium  received. The Underlying Theme Portfolios do not consider a security or
currency covered by a call option to be "pledged" as that term is used in  their
policies that limit the pledging or mortgaging of their assets.
 
Writing  call options can serve as a limited short hedge because declines in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
appreciates to a price higher than the exercise price of the call option, it can
be expected that the option will be exercised and an Underlying Theme  Portfolio
will  be obligated  to sell  the security  or currency  at less  than its market
value.
 
The premium  that an  Underlying Theme  Portfolio receives  for writing  a  call
option  is deemed to constitute  the market value of  an option. The premium the
Underlying Theme Portfolio will receive from writing a call option will reflect,
among other things, the current market  price of the underlying investment,  the
relationship  of the exercise  price to such market  price, the historical price
volatility of the underlying investment, and the length of the option period. In
determining whether a particular call option should be written, the Manager will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing transactions  will  be effected  in  order to  realize  a profit  on  an
outstanding  call option,  to prevent  an underlying  security or  currency from
being called  or to  permit the  sale of  the underlying  security or  currency.
Furthermore,  effecting a  closing transaction  will permit  an Underlying Theme
Portfolio to write another  call option on the  underlying security or  currency
with either a different exercise price or expiration date, or both.

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 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.
 
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
 
                   Statement of Additional Information Page 9
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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 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
 
                  Statement of Additional Information Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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
 
                  Statement of Additional Information Page 12
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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
 
                  Statement of Additional Information Page 13
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
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
 
                  Statement of Additional Information Page 14
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 FUNDS
 
- --------------------------------------------------------------------------------
 
DEBT SECURITIES
The  value  of  the debt  securities  held  by each  Underlying  Theme Portfolio
generally will vary conversely with market interest rates. If interest rates  in
a  market fall, the value  of the debt securities  held by each Underlying Theme
Portfolio ordinarily will rise. If market interest rates increase, however,  the
debt  securities owned by each Underlying Theme Portfolio in that market will be
likely to decrease in value.
 
The Global  Consumer  Products  and Services  Portfolio,  Global  Infrastructure
Portfolio,  and Global Natural Resources Portfolio may  each invest up to 20% of
its  total  assets  in  debt  securities  rated  below  investment  grade.  Such
investments  involve a high  degree of risk. However,  those Portfolios will not
invest in debt securities  that are in  default as to  payment of principal  and
interest.
 
Debt  rated Baa  by Moody's Investors  Service, Inc. ("Moody")  is considered by
Moody's to have speculative characteristics. Debt rated  BB, B, CCC, CC or C  by
Standard  & Poor's, a  division of The McGraw-Hill  Companies, Inc. ("S&P"), and
debt rated  Ba,  B,  Caa, Ca  or  C  by  Moody's is  regarded,  on  balance,  as
predominantly  speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. For S&P,  BB
indicates the lowest degree of speculation for such lower quality debt and C the
highest  degree of speculation. For Moody's,  Baa indicates the lowest degree of
speculation for such lower quality debt and C the highest degree of speculation.
While such  lower quality  debt will  likely have  some quality  and  protective
characteristics,  these  are outweighed  by  large uncertainties  or  major risk
exposures to adverse conditions. Debt  rated C by Moody's  or S&P is the  lowest
rated  debt that is  not in default as  to principal or  interest, and issues so
rated can be regarded as having  extremely poor prospects of ever attaining  any
real  investment  standing. Lower  quality  debt securities  also  are generally
considered to be  subject to greater  risk than securities  with higher  ratings
with  regard  to a  deterioration of  general  economic conditions.  These lower
quality debt  securities are  the equivalent  of high  yield, high  risk  bonds,
commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality  and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments  and do not evaluate the risks  of
fluctuations  in market  value. Also,  rating agencies  may fail  to make timely
changes in credit ratings in response to subsequent events, so that an  issuer's
current financial condition may be better or worse than a rating indicates.
 
The  market values of  lower quality debt securities  tend to reflect individual
developments  of  the  issuer  to  a  greater  extent  than  do  higher  quality
securities,  which  react  primarily to  fluctuations  in the  general  level of
interest rates.  In addition,  lower quality  debt securities  tend to  be  more
sensitive  to economic conditions  and generally have  more volatile prices than
higher quality securities. Issuers of lower quality securities are often  highly
leveraged  and  may  not have  available  to  them more  traditional  methods of
financing. For example,  during an economic  downturn or a  sustained period  of
rising interest
 
                  Statement of Additional Information Page 15
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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
 
                  Statement of Additional Information Page 16
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 STABILITY.  Certain countries  in which an
Underlying Theme  Portfolio may  invest may  have groups  that advocate  radical
religious  or  revolutionary philosophies  or  support ethnic  independence. Any
disturbance on  the part  of  such individuals  could  carry the  potential  for
widespread  destruction  or confiscation  of property  owned by  individuals and
entities foreign to such country and could cause the loss of an Underlying Theme
Portfolio's investment in  those countries.  Instability may  also result  from,
among  other things,  (i) authoritarian  governments or  military involvement in
political and economic decision-making, including changes in government  through
extra-constitutional  means,  (ii) popular  unrest  associated with  demands for
improved political, economic and social conditions, and (iii) hostile  relations
with  neighboring  or  other  countries.  Such  political,  social  and economic
instability could disrupt the principal financial markets in which an Underlying
Theme Portfolio invests and adversely affect the value of its assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity markets, by foreign entities such as an Underlying Theme Portfolio.
These restrictions or  controls may at  times limit or  preclude investments  in
certain securities and may increase the cost and expenses of an Underlying Theme
Portfolio.  For example,  certain countries require  prior governmental approval
before investments by foreign  persons may be  made or may  limit the amount  of
investment by foreign persons in a particular company or limit the investment by
foreign  persons to only  a specific class  of securities of  a company that may
have less  advantageous  terms than  securities  of the  company  available  for
purchase  by nationals. Moreover, the national policies of certain countries may
restrict investment opportunities in issuers  or industries deemed sensitive  to
national  interests. In  addition, some countries  require governmental approval
for the repatriation of investment income, capital or the proceeds of securities
sales by  foreign investors.  In addition,  if  there is  a deterioration  in  a
country's  balance  of  payments or  for  other  reasons, a  country  may impose
restrictions  on  foreign  capital  remittances  abroad.  An  Underlying   Theme
Portfolio  could be adversely affected by delays  in, or a refusal to grant, any
required governmental approval for repatriation,  as well as by the  application
to it of other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting principles.  Most of  the securities held  by an  Underlying
Theme Portfolio will not be registered with the SEC or regulators of any foreign
country, nor will the issuers
 
                  Statement of Additional Information Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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.
 
    WITHHOLDING TAXES. Each Underlying  Theme Portfolio's net investment  income
from  securities of its 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.
 
                  Statement of Additional Information Page 18
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
    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  judgement; (3)  pervasiveness of
corruption and  crime  in  the  economic  system;  (4)  currency  exchange  rate
volatility  and the lack  of available currency  hedging instruments; (5) higher
rates of inflation (including the risk of social unrest associated with  periods
of  hyper-inflation) and high  unemployment; (6) controls  on foreign investment
and  local   practices  disfavoring   foreign  investors   and  limitations   on
repatriation of invested capital, profits and dividends, and on a fund's ability
to  exchange local  currencies for U.S.  dollars; (7)  political instability and
social unrest and  violence; (8)  the risk that  the governments  of Russia  and
Eastern  European countries may  decide not to continue  to support the economic
reform programs  implemented  recently  and  could  follow  radically  different
political  and/or  economic policies  to the  detriment of  investors, including
non-market-oriented policies such as  the support of  certain industries at  the
expense  of other  sectors or  investors, or a  return to  the centrally planned
economy that existed when such countries had a communist form of government; (9)
the financial condition of companies in these countries, including large amounts
of inter-company debt which  may create a payments  crisis on a national  scale;
(10)  dependency on  exports and  the corresponding  importance of international
trade; (11) the risk that the tax system in these countries will not be reformed
to prevent inconsistent,  retroactive and/or exorbitant  taxation; and (12)  the
underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly  since 1990. The general government position has deteriorated as a
result of weakening economic  growth and stimulative  measures taken to  support
economic  activity and to  restore financial stability.  Although the decline in
interest  rates  and  fiscal  stimulation   packages  have  helped  to   contain
recessionary  forces, uncertainties remain. Japan is also heavily dependent upon
international trade, so its  economy is especially  sensitive to trade  barriers
and  disputes.  Japan has  had difficult  relations  with its  trading partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible that  trade sanctions  and other  protectionist measures  could  impact
Japan adversely in both the short and the long term.
 
The  common  stocks  of many  Japanese  companies trade  at  high price-earnings
ratios. Differences  in accounting  methods  make it  difficult to  compare  the
earnings  of  Japanese companies  with those  of  companies in  other countries,
especially in the  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
 
                  Statement of Additional Information Page 19

                          GT GLOBAL NEW DIMENSION FUND
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
 
- --------------------------------------------------------------------------------
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;
 
        (3)  purchase  securities  on  margin,  except  for  short-term   credit
    necessary  for clearance of portfolio transactions  and except that the Fund
    may make margin deposits in connection with its use of financial options and
    futures, forward and  spot currency contracts,  swap transactions and  other
    financial contract or derivative instruments;
 
                  Statement of Additional Information Page 21
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (4)  engage in short  sales of securities or  maintain a short position,
    except that the Fund may (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;
 
        (5)  Purchase  securities on  margin, provided  that each  Portfolio may
    obtain such short-term  credits as  may be  necessary for  the clearance  of
    purchases  and sales of securities; except  that it may make margin deposits
    in connection with futures contracts;
 
                  Statement of Additional Information Page 22

                          GT GLOBAL NEW DIMENSION FUND
 
        (6) Borrow money except from banks not in excess of 33 1/3% of the value
    of each Portfolio's total assets, (including the amount borrowed), less  all
    liabilities  and indebtedness  (other than the  borrowing). This restriction
    shall not  prevent  any  Portfolio from  entering  into  reverse  repurchase
    agreements,  provided  that  reverse repurchase  agreements,  and  any other
    transactions constituting borrowing by a Portfolio may not exceed  one-third
    of  that Portfolio's  total assets. Transactions  involving options, futures
    contracts, options on futures contracts  and forward currency contracts,  as
    described  in 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.
 
                  Statement of Additional Information Page 23
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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.
 
TELECOMMUNICATIONS FUND
 
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;
 
        (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;
 
                  Statement of Additional Information Page 24
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (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
    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  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;
 
        (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  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
 
        (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
 
                  Statement of Additional Information Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
assets in any one investment company or acquire more than 3% of the  outstanding
voting securities of any one investment company.
 
Investors  should refer  to the Underlying  Theme Funds'  prospectus for further
information with respect to the Telecommunications Fund's investment  objective,
which may not be changed without a Required Vote, and other investment policies,
techniques and limitations, which may be changed without shareholder approval.
 
If  a  percentage  restriction on  investment  or  utilization of  assets  in an
investment policy or  restriction is  adhered to at  the time  an investment  is
made, a later change in percentage ownership of a security or kind of securities
resulting  from changing market  values or a  similar type of  event will not be
considered a violation of the  Underlying Theme Portfolio's investment  policies
or restrictions. An Underlying Theme Portfolio may exchange securities, exercise
conversion  or subscription rights, warrants or  other rights to purchase common
stock or other equity securities and may  hold, except to the extent limited  by
the  1940 Act, any such securities so  acquired without regard to the Underlying
Theme Portfolio's investment policies and restrictions. The original cost of the
securities so acquired will be included  in any subsequent determination of  the
Underlying   Theme  Portfolio's   compliance  with   the  investment  percentage
limitations referred to above and in the Prospectus.

                             EXECUTION OF PORTFOLIO
                                  TRANSACTIONS
 
- --------------------------------------------------------------------------------
All orders  for  the purchase  or  sale of  portfolio  securities for  the  Fund
(normally shares of the Underlying Theme Funds) are placed on behalf of the Fund
by  the  Manager. As  stated in  the  Prospectus, the  Manager will  exercise no
discretion in investing the assets of the Fund other than to make investments in
money market instruments and to rebalance the percentage of the Fund's assets in
each Underlying Theme Fund.
 
Subject to  policies  established  by  the  applicable  Board,  the  Manager  is
responsible  for the execution  of each Underlying  Theme Portfolio's securities
transactions and the selection of  broker/dealers who execute such  transactions
on  behalf of  each Underlying Theme  Portfolio. In  executing transactions, the
Manager seeks the best net results  for each Underlying Theme Portfolio,  taking
into  account  such factors  as the  price  (including the  applicable brokerage
commission or dealer  spread), size of  the order, difficulty  of execution  and
operational  facilities  of the  firm involved.  Although the  Manager generally
seeks reasonably competitive commission rates and spreads, payment of the lowest
commission or spread is  not necessarily consistent with  the best net  results.
While each Underlying Theme Portfolio may engage in soft dollar arrangements for
research  services, as described  below, it has  no obligation to  deal with any
broker/dealer  or  group  of  broker/dealers  in  the  execution  of   portfolio
transactions.
 
Consistent  with the interests  of each Underlying  Theme Portfolio, the Manager
may select broker/dealers to execute that Underlying Theme Portfolio's portfolio
transaction on the basis of the research and brokerage services they provide  to
the  Manager for  its use  in managing that  Underlying Theme  Portfolio and its
other advisory accounts. Such services may include furnishing analyses,  reports
and  information concerning issuers, industries, securities, geographic regions,
economic factors and  trends, portfolio strategy,  and performance of  accounts;
and  effecting  securities  transactions  and  performing  functions  incidental
thereto (such  as clearance  and settlement).  Research and  brokerage  services
received  from such broker are in addition to,  and not in lieu of, the services
required to  be  performed  by  the  Manager  under  investment  management  and
administration  contracts. A commission  paid to such broker  may be higher than
that which another qualified  broker would have charged  for effecting the  same
transaction,  provided  that  the Manager  determines  in good  faith  that such
commission is reasonable in terms either  of that particular transaction or  the
overall  responsibility of the Manager to the Underlying Theme Portfolio and its
other clients  and that  the total  commissions paid  by that  Underlying  Theme
Portfolio  will be reasonable  in relation to  the benefits it  receive over the
long term.  Research services  may also  be received  from dealers  who  execute
portfolio transactions in OTC markets.
 
The  Manager  may allocate  brokerage  transactions to  broker/dealers  who have
entered into arrangements under which  the broker/dealer allocates a portion  of
the  commissions paid  by an  Underlying Theme  Portfolio toward  payment of its
expenses, such as custodian fees.
 
Investment decisions for an Underlying Theme Portfolio and for other  investment
accounts managed by the Manager are made independently of each other in light of
differing   conditions.  However,  the  same  investment  decision  occasionally
 
                  Statement of Additional Information Page 26
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 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.

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  fee for  providing management  services to  the
Fund.
 
DISTRIBUTION SERVICES RELATING TO THE FUND
The  Fund's Advisor  Class shares  are offered  continuously through  the Fund's
principal underwriter  and distributor,  GT Global,  on a  "best efforts"  basis
without a sales charge or contingent deferred sales charge.
 
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

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

PAYMENT AND TERMS OF OFFERING
Payment  for Advisor  Class 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
 
                  Statement of Additional Information Page 30
<PAGE>

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.
 
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. Advisor Class shares
of the Fund may be  exchanged only for Advisor Class  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.
 
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 its  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
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
 
                  Statement of Additional Information Page 32
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
aware  that  if shares  are purchased  shortly  before the  record date  for any
dividend or other  distribution, the  shareholder will  pay full  price for  the
shares and receive some portion of the price back as a taxable distribution.
 
Dividends  paid by the Fund to a shareholder  who, as to the United States, is a
nonresident alien  individual, or  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 An 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.

- --------------------------------------------------------------------------------
 
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.

other expenses incurred therewith. Thus, the risk of any shareholder's incurring
financial  loss  beyond  his  or her  investment,  because  of  this theoretical
shareholder liability, is  limited to  circumstances in  which the  Fund or  the
Trust itself would be unable to meet its obligations.

                               INVESTMENT RESULTS
 
- --------------------------------------------------------------------------------
 
STANDARDIZED RETURNS
The  Fund's "Standardized Returns," as referred to in the Prospectus (see "Other
Information --  Performance  Information"  in  the  Prospectus),  is  calculated
separately  for  Class A,  Class  B and  Advisor Class  shares  of the  Fund, as
follows: Standardized Return (average annual total return ("T")) is computed  by
using the ending redeeming value ("ERV") of a hypothetical initial investment of
$1,000  ("P") over a period of years ("n") according to the following formula as
required by the SEC: P(1+T) to the (n)th power = ERV. The following  assumptions
will  be reflected  in computations  made in  accordance with  this formula: (1)
reinvestment of dividends  and other  distributions at  net asset  value on  the
reinvestment  date  determined  by the  Trust's  Board  of Trustees;  and  (2) a
complete redemption at the end of any period illustrated.
 
NON-STANDARDIZED RETURNS
In  addition   to  Standardized   Returns,  the   Fund  also   may  include   in
advertisements,  sales  literature and  shareholder  reports other  total return
performance  data  ("Non-Standardized   Return").  Non-Standardized  Return   is
calculated  separately for Class A, Class B and Advisor Class 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.
 
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) reinvestment of dividends
and other distributions at net asset  value on the reinvestment date  determined
by  the  Board;  and  (2)  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, 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

Information  relating  to   foreign  market   performance,  capitalization   and
diversification  is based on sources believed to  be reliable but may be subject
to revision and has not  been independently verified by  the Fund or GT  Global.
The  authors  and  publishers of  such  material  are not  to  be  considered as
"experts" under the 1933  Act, on account of  the inclusion of such  information
herein.
 
A  portion of the performance  figures for each market  includes the positive or
negative effects of the currency exchange rates effective at December 31 of each
year between the U.S. dollar and currency of the foreign market (e.g.,  Japanese
Yen,  German Deutschemark,  and Hong Kong  Dollar). A foreign  currency that has
strengthened or weakened against the  U.S. dollar will positively or  negatively
affect the reported returns, as the case may be.
 
GT  Global believes that this information may be useful to investors considering
whether and to what extent to  diversify their investments through the  purchase
of mutual funds investing in securities on a global basis. However, this data is
not a representation of the past performance of the Fund, nor is it a prediction
of such performance. The performance of the Fund will differ from the historical
performance  of  relevant  indices. The  performance  of indices  does  not take
expenses into account, while the Fund  incurs expenses in its operations,  which
will reduce performance. Each of these factors will cause the performance of the
Fund to differ from relevant indices.
 
From  time  to  time,  the  Fund  and GT  Global  may  refer  to  the  number of
shareholders in  the Fund  or the  aggregate number  of shareholders  in all  GT
Global  Mutual Funds or the dollar amount  of the Fund's assets under management
or rankings by DALBAR Surveys, Inc. in advertising materials.
 
GT  Global  believes  the  Fund  is  an  appropriate  investment  for  long-term
investment   goals  including  funding  retirement,   paying  for  education  or
purchasing  a  house.  GT  Global  may  provide  information  designed  to  help
individuals  understand  their investment  goals  and explore  various financial
strategies. For example, GT Global may describe general principles of investing,
such as asset allocation, diversification and risk tolerance. The Fund does  not
represent  a complete investment program, and investors should consider the Fund
as appropriate for a portion of  their overall investment portfolio with  regard
to  their  long-term  investment goals.  There  is  no assurance  that  any such
information will lead to achieving these goals or guarantee future results.
 
From time to time,  GT Global may refer  to or advertise the  names of U.S.  and
non-U.S.  companies and their products, although  there can be no assurance that
any GT Global Mutual Fund may own the securities of these companies.
 
Ibbotson Associates of Chicago, Illinois (Ibbotson) provides historical  returns
of  the capital  markets in  the United  States, including  common stocks, small
capitalization stocks, long-term  corporate bonds, intermediate-term  government
bonds,  long-term government bonds,  Treasury bills, the  U.S. rate of inflation
(based on the CPI), and combinations of various capital markets. The performance
of these capital markets are based on the returns of different indices.
 
GT Global Mutual Funds may use the performance of these capital markets in order
to demonstrate  general  risk-versus-reward  investment  scenarios.  Performance
comparisons  may also include the  value of a hypothetical  investment in any of
these capital  markets. The  risks associated  with the  security types  in  any
capital  market  may or  may  not correspond  directly  to those  of  the funds.
Ibbotson calculates total returns in the same method as the funds.
 
The Fund may quote various measures of volatility and benchmark correlation such
as beta, standard  deviation and  R in advertising.  In addition,  the Fund  may
compare  these measures to those of other  funds. Measures of volatility seek to
compare the Fund's historical share price fluctuations or total returns compared
to those  of  a  benchmark.  All measures  of  volatility  and  correlation  are
calculated using averages of historical data.
 
The  Fund may  advertise examples of  the effects of  periodic investment plans,
including the principle of dollar cost averaging programs. In such a program, an
investor invests a fixed dollar amount in a fund at periodic intervals,  thereby
purchasing  fewer shares when  prices are high  and more shares  when prices are
low. While such a strategy does not assure  a profit or guard against loss in  a
declining  market, the investor's  average cost per  share can be  lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating  such
a  plan, investors should  consider their ability  to continue purchasing shares
through periods of low price levels.

The Fund  may  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.
 
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, the Fund and GT Global will quote data regarding industries,
companies, individual countries,  regions, world stock  exchanges, and  economic

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

                          DESCRIPTION OF DEBT RATINGS
 
- --------------------------------------------------------------------------------
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
Moody's  employs the designations "Prime-1" and "Prime-2" to indicate commercial
paper having the highest  capacity for timely  repayment. Issuers rated  Prime-1
(or  supporting institutions)  have a superior  ability for  repayment of senior
short-term debt obligations. Prime-1 repayment  ability will often be  evidenced
by   many  of  the  following   characteristics:  leading  market  positions  in
well-established  industries;   high  rates   of  return   on  funds   employed;
conservative  capitalization structure with moderate  reliance on debt and ample
asset protection; broad margins in earnings coverage of fixed financial  charges
and  high internal  cash generation; and  well-established access to  a range of
financial markets  and assured  sources of  alternate liquidity.  Issuers  rated
Prime-2  (or supporting  institutions) have  a strong  ability for  repayment of
senior short-term debt obligations. This normally  will be evidenced by many  of
the  characteristics cited  above but  to a  lesser degree.  Earnings trends and
coverage ratios, while sound  may be more  subject to variation.  Capitalization
characteristics,  while  still appropriate,  may  be more  affected  by external
conditions. Ample alternate liquidity is maintained.
 
S&P rates commercial paper in four categories ranging from "A-1" for the highest
quality obligations  to  "D"  for  the lowest.  A-1  --  This  highest  category
indicates  that the degree  of safety regarding timely  payment is strong. Those
issues determined to  possess extremely  strong safety  characteristics will  be
denoted  with a plus sign (+) designation. A-2 -- Capacity for timely payment on
issues with this designation  is satisfactory. However,  the relative degree  of
safety  is not as  high as for  issues designated "A-1."  A-3 -- Issues carrying
this designation have adequate capacity  for timely payment. They are,  however,
more  vulnerable  to  the  adverse  effects  of  changes  in  circumstances than
obligations carrying the higher designations. B -- Issues rated "B" are regarded
as having only  speculative capacity  for timely payment.  C --  This rating  is
assigned  to short-term debt obligations with a doubtful capacity for payment. D
- -- Debt rated "D" is  in payment default. The "D"  rating category is used  when
interest  payments or principal payments  are not made on  the date due, even if
the applicable  grace period  has not  expired, unless  S&P believes  that  such
payments will be made during such grace period.
 
DESCRIPTION OF BOND RATINGS
Moody's  rates the  long-term debt  securities issued  by various  entities from
"Aaa" to "C." Investment Grade Ratings are the first four categories:
 
        Aaa --  Best quality.  These  securities carry  the smallest  degree  of
    investment  risk and  are generally  referred to  as "gilt  edged." Interest
    payments are protected by a large  or by an exceptionally stable margin  and
    principal  is secure.  While the various  protective elements  are likely to
    change, such changes as  can be visualized are  most unlikely to impair  the
    fundamentally strong position of such issues.
 
        Aa  -- High quality by  all standards. Together with  the Aaa group they
    comprise what are generally known as high grade bonds. They are rated  lower
    than  the best bonds because margins of protection may not be as large as in
    Aaa securities  or fluctuation  of  protective elements  may be  of  greater
    amplitude  or there may  be other elements present  which make the long-term
    risk appear somewhat larger than the Aaa securities.
 
        A  --  Upper-medium-grade  obligations.   Factors  giving  security   to
    principal  and interest are considered adequate, but elements may be present
    which suggest a susceptibility to impairment sometime in the future.
 
        Baa -- Medium-grade obligations (i.e., they are neither highly protected
    nor  poorly  secured).  Interest  payments  and  principal  security  appear
    adequate  for the present but certain  protective elements may be lacking or
    may be characteristically  unreliable over  any great length  of time.  Such
    bonds   lack  outstanding  investment  characteristics   and  in  fact  have
    speculative characteristics as well.
 
        Ba -- Have speculative elements and their future cannot be considered as
    well-assured. Often the protection of interest and principal payments may be
    very moderate, and  thereby not well  safeguarded during both  good and  bad
    times  over the future. Uncertainty of  position characterizes bonds in this
    class.
 
        B  --  Generally  lack  characteristics  of  the  desirable  investment.
    Assurance  of interest  and principal  payments or  of maintenance  of other
    terms of the contract over any long period of time may be small.

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

<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.

Global New Dimension Fund (the "Fund") as of August 18, 1997. This financial
statement is the responsibility of the Fund's management. Our responsibility is
to express an opinion on this financial statement based on our audit.
 
We conducted our audit in accordance with generally accepted auditing standards.

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,
in conformity with generally accepted accounting principles.
