                         PROSPECTUS -- JANUARY 1, 1998
    
 
- --------------------------------------------------------------------------------
 
GT GLOBAL NEW DIMENSION FUND (the "Fund") is a diversified series of GT Global
Series Trust (the "Trust"), an open-end management investment company. The Fund
seeks long-term growth of capital. Unlike a typical mutual fund, which invests
directly in portfolio securities, the Fund invests primarily in shares of the GT
Global theme mutual funds: GT Global Consumer Products and Services Fund; GT
Global Financial Services Fund; GT Global Health Care Fund; GT Global
Infrastructure Fund; GT Global Natural Resources Fund; and GT Global
Telecommunications Fund (collectively, the "Underlying Theme Funds").
 
There is no assurance that the Fund will achieve its investment objective.
 
FUND SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR ENDORSED OR GUARANTEED BY,
ANY BANK, NOR ARE THEY FEDERALLY INSURED OR OTHERWISE PROTECTED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY.
 
The Fund is managed by Chancellor LGT Asset Management, Inc. (the "Manager").
The Manager and its worldwide affiliates are part of Liechtenstein Global Trust,
a provider of global asset management and private banking products and services
to individual and institutional investors.
 
   
This Prospectus sets forth concisely the information an investor should know
before investing and should be read carefully and retained for future reference.
A Statement of Additional Information, dated January 1, 1998, has been filed
with the Securities and Exchange Commission ("SEC") and, as supplemented or
amended from time to time, is incorporated by reference. The Statement of
Additional Information is available without charge by writing to the Fund at 50
California Street, 27th Floor, San Francisco, California 94111, or by calling
(800) 824-1580. It is also available, along with other related materials, on the
SEC's Internet web site (http://www.sec.gov).

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
                               recently organized entity, the Fund has a limited operating
                               history.
Investment Manager:            The Manager is part of Liechtenstein Global Trust, a provider of
                               global asset management and private banking products and services
                               to individual and institutional investors, entrusted with
                               approximately $87 billion in total assets as of June 30, 1997. The
                               Manager and its worldwide asset management affiliates maintain

*   Sales charge waivers are available for Class A, Class B and Class C shares,
    and reduced sales charges are available for Class A shares. The maximum 5%
    contingent deferred sales charge on Class B shares applies to redemptions
    during the first year after purchase. The charge declines thereafter,
    reaching zero after six years. Class C shares redeemed within the first year
    after purchase are subject to a 1% contingent deferred sales charge. See
    "How to Invest."
    
 
   
+   The Annual Fund Operating Expenses are estimated for the Fund's initial
    fiscal period. "Other expenses" (including transfer agency, legal and audit
    fees and other operating expenses) initially will be borne by the Manager.
    Subject to receipt of an order of the SEC pursuant to a pending exemptive
    application and a private letter ruling issued by the Internal Revenue
    Service, such expenses may be shared by the Manager and the Underlying Theme
    Funds or the Underlying Theme Funds alone. See "Other Information -- Special
    Servicing Agreement." Long-term shareholders may pay more than the economic
    equivalent of the maximum front-end sales charge permitted by the National
    Association of Securities Dealers, Inc. rules regarding investment
    companies. See "Management" and the Statement of Additional Information for
    more information. The Fund also offers Advisor Class shares, which are not
    subject to 12b-1 distribution and service fees, to certain categories of
    investors. See "Alternative Purchase Plan."
    
 
   
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 their fiscal years ended October 31, 1997.

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 November
30, 1997, plus the Fund's total operating expenses. For this purpose the expense
ratios of the Underlying Theme Funds are for their fiscal years ended October
31, 1997 (as set forth in the preceding table).

THE FOREGOING TABLES ARE INTENDED TO ASSIST INVESTORS IN UNDERSTANDING THE
VARIOUS COSTS AND EXPENSES ASSOCIATED WITH INVESTING IN THE FUND. THE
"HYPOTHETICAL EXAMPLE" IS NOT A REPRESENTATION OF FUTURE EXPENSES. THE FUND'S
ACTUAL DIRECT AND INDIRECT EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN. The
example assumes payment by the Fund of operating expenses at the level set forth
under "Annual Fund Operating Expenses" above and of its indirect pro rata share
of the Advisor Class share expenses of the Underlying Theme Funds, as described
above.
    
 
The tables and the assumption in the Hypothetical Example of a 5% annual return
are required by regulations of the SEC applicable to all mutual funds. The 5%
annual return is not a prediction of and does not represent the Fund's or any
Underlying Theme Fund's projected or actual performance.

                            INVESTMENT OBJECTIVE AND
                                    POLICIES
    
 
- --------------------------------------------------------------------------------
 
   
The Fund seeks long-term growth of capital. Unlike a typical mutual fund, which
invests directly in securities, the Fund invests 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 Manager exercises no discretion in investing the Fund's assets. Rather, the
Manager periodically determines the allocation of the Fund's assets to the
Underlying Theme Funds according to the industry weightings of the companies
composing the Morgan Stanley Capital International All Country (AC) World Index
("MSCI"). (The MSCI is a broad unmanaged index of global stock prices, currently
comprising approximately 2,500 different issuers, located in 47 countries
including 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 its primary focus, in each of
these industries. For example, industries in the MSCI in which the Financial
Services Fund invests include the Banking, Financial Services, Insurance and
Real Estate industries. The percentage that those industries compose in the MSCI
is the initial weighting assigned to the Financial Services Fund. Where two or
more Underlying Theme Funds can invest in an industry, the weighting of that
industry in the MSCI is split equally among each qualifying Underlying Theme
Fund. See the Appendix for the allocation of the 38 industries to the Underlying
Theme Funds. Of course, the Underlying Theme Funds do not invest necessarily in
the same industries or the same companies that compose the MSCI. Because the
percentage weight assigned to each industry in the MSCI changes over time and
because the percentage of the Fund's assets invested in each Underlying Theme
Fund will change over time, the Manager will rebalance the Fund's assets among
the Underlying Theme Funds at least semi-annually. In addition, the Manager will
invest incoming money in, and satisfy redemption requests by redeeming shares
of, each Underlying Theme Fund according to the MSCI weighting as of the last
business day of the preceding month. As of November 30, 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......          %
Financial Services Fund..................          %
Health Care Fund.........................          %
Infrastructure Fund......................          %
Natural Resources Fund...................          %
Telecommunications Fund..................          %
</TABLE>
    
 
   
These percentages do not necessarily reflect the actual weighting of the Fund's
assets among the Underlying Theme Funds because of changes in market valuations.
    
 
   
The Fund is a more diversified investment than any single Underlying Theme Fund.
However, because the Underlying Theme Funds are actively managed without any
attempt to reflect the country, industry or company weightings of the MSCI, the
Underlying Theme Funds will perform differently than the corresponding industry
components of the MSCI, and the Underlying Theme Funds will perform differently
than the overall MSCI. While the Fund does not therefore represent the
performance of the MSCI, it does represent a globally diversified portfolio,
with allocations among developed and emerging countries, industries and
companies intended to achieve long-term growth of capital.
    
 
   
The Fund is designed to meet the needs of investors who seek professional money
management services and who appreciate the advantages of diversification. The
Fund by itself should not be considered a complete investment program. As a
recently organized entity, the Fund has a limited operating history.
    
 
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,

                                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.
In addition, the industries in which the Underlying Theme Funds invest may be
subject to political, environmental or other governmental regulation. Changes in
these factors may have a material effect on the products and services offered by
companies in these industries.
    
 
UNDERLYING THEME FUNDS' INVESTMENT ALLOCATION. The Manager allocates each
Underlying Theme Fund's (or its corresponding Portfolio's) assets among
securities of countries and in currency denominations where opportunities for
meeting each Underlying Theme Fund's investment objective are expected to be the
most attractive. Each Underlying Theme Fund may invest substantially in
securities denominated in foreign currencies. Under normal conditions, each
Underlying Theme Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 40% of the Financial Services Portfolio's and the Telecommunication Fund's
total assets, and no more than 50% of the Infrastructure Portfolio's, the
Natural Resources Portfolio's, the Health Care Fund's and the Consumer Products
and Services Portfolio's total assets.
 
In analyzing specific companies for possible investment the Manager, on behalf
of the Underlying Theme Funds, ordinarily looks for several of the following
characteristics: above-average per share earnings growth; high return on
invested capital; a healthy balance sheet; sound financial and accounting
policies and overall financial strength; strong competitive advantages;
effective research and product development and marketing; development of new
technologies; efficient service; pricing flexibility; strong management; and
general operating characteristics that will enable the companies to compete
successfully in their respective markets. In assessing companies for the Natural
Resources Portfolio, the Manager will also evaluate, among other factors, their
capabilities for expanded exploration and production, superior exploration
programs and production techniques and facilities, current inventories, expected
production and demand levels and the potential to accumulate new resources.
 
FOREIGN INVESTMENTS. The Underlying Theme Funds' investments in foreign
securities may involve risks in addition to those of U.S. investments, including
increased political and economic risk, as well as exposure to currency
fluctuations. By investing in foreign securities, the Underlying Theme Funds
also have increased economic and political risks as they are exposed to events
and factors in the various world markets. This is especially true of an
Underlying Theme Fund that invests in emerging markets. Many investments in
emerging markets are considered speculative and therefore may offer greater
return potential, but have significantly greater risk. Also, to the extent that
an Underlying Theme Fund's investments are denominated in foreign currencies,
changes in the value of foreign currencies can significantly affect the Fund's
share price.
 
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
 
                               Prospectus Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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; and (6) the
possible inability of an Underlying Theme Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for an Underlying Theme Fund to sell a security at a
disadvantageous time, due to the need for the Underlying Theme Fund to maintain
"cover" or to set aside securities in connection with hedging transactions.
    
 
INVESTING IN SMALLER COMPANIES. Each Underlying Theme Fund may invest in smaller
companies that may present greater opportunities for capital appreciation, but
may also involve greater risks than large, established issuers. Such smaller
companies may have limited resources, and their securities may trade less
frequently and in more limited volume than the securities of larger, more
established companies. As a result, the prices of the securities of such smaller
companies may fluctuate to a greater degree than the prices of the securities of
other issuers.
 
PURCHASES AND REDEMPTIONS. From time to time, the Underlying Theme Funds may
experience relatively large purchases or redemptions due to rebalancing of the
Fund by the Manager. This may have a material effect on the Underlying Theme
Funds, because Underlying Theme Funds that experience redemptions as a result of
the rebalancing may have to sell portfolio securities and because Underlying
Theme Funds that receive additional cash will have to invest it. While it is
impossible to predict the overall impact of these transactions over time, there
could be adverse effects on portfolio management to the extent that Underlying
Theme Funds may be required to sell securities at times when they would not
otherwise do so, or receive cash that cannot be invested in an expeditious
manner. There may be tax consequences associated with purchases and sales of
securities, and such sales also may increase transaction costs.
 
                               Prospectus Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
MASTER-FEEDER STRUCTURE OF CERTAIN UNDERLYING THEME FUNDS. The Financial
Services Fund, Infrastructure Fund, Natural Resources Fund and Consumer Products
and Services Fund, unlike mutual funds that directly acquire and manage their
own portfolios of securities, each seeks its investment objective by investing
all of its investable assets in the Financial Services Portfolio, Infrastructure
Portfolio, Natural Resources Portfolio and Consumer Products and Services
Portfolio (each a "Portfolio"), respectively. Each Portfolio is a separate
investment company. Because each such Underlying Theme Fund will invest only in
its corresponding Portfolio, that Underlying Theme Fund's shareholders will
acquire only an indirect interest in the investments of that Portfolio.
 
TEMPORARY DEFENSIVE STRATEGIES. The Underlying Theme Funds retain the
flexibility to respond promptly to changes in market and economic conditions.
Accordingly, in the interest of preserving shareholders' capital the Manager may
employ a temporary defensive investment strategy if it determines such a
strategy to be warranted due to market, economic or political conditions. Under
a defensive strategy, the Underlying Theme Funds may invest up to 100% of their
total assets in cash and/or high quality debt securities and money market
instruments. To the extent an Underlying Theme Fund adopts a temporary defensive
posture, it will not be invested so as to achieve directly its investment
objective.
 
   
In addition, pending investment of proceeds from new sales of the shares or to
meet its ordinary daily cash needs, the Underlying Theme Funds may hold cash
and/or may invest in high quality debt instruments and money market instruments.
The Fund may hold cash and/or may invest in money market instruments under
similar circumstances. Money market instruments in which the Underlying Theme
Funds and the Fund may invest include, but are not limited to, United States
government securities; high-grade commercial paper; bank certificates of
deposit; bankers' acceptances and repurchase agreements related to any of the
foregoing. "High-grade commercial paper" refers to commercial paper rated A-1 by
Standard & Poor's, a division of The McGraw-Hill Companies, Inc., or P-1 by
Moody's Investors Service, Inc. or, if not rated, determined by the Manager to
be of comparable quality.
    
 
PORTFOLIO TURNOVER. The Fund's portfolio turnover rate is expected to be low and
is not anticipated to exceed 20% annually. The portfolio turnover rates of the
Underlying Theme Funds and their corresponding Portfolios have ranged from 37%
to 169% during their most recent fiscal years. There is no assurance that the
turnover rates of the Underlying Theme Funds and their corresponding Portfolios
will remain within this range during subsequent fiscal years. Higher turnover
rates may result in higher expenses being incurred by the Underlying Theme
Funds.
 
AFFILIATED PERSONS. The officers and trustees of the Trust currently serve as
officers and trustees of the Underlying Theme Funds. The Manager also serves as
investment adviser and/or administrator to the Underlying Theme Funds.
Therefore, conflicts may arise as these persons fulfill their fiduciary
responsibilities to the Fund and the Underlying Theme Funds.
 
Further information on the investment policies, practices and risks of the
Underlying Theme Funds can be found in the Statement of Additional Information
as well as the Underlying Theme Funds' prospectus and statement of additional
information.

                                 HOW TO INVEST
 
- --------------------------------------------------------------------------------
 
   
GENERAL. All purchase orders will be executed at the public offering price next
determined after the purchase order is received, which includes any applicable
sales charge for Class A shares. Orders received before the close of regular
trading on the New York Stock Exchange ("NYSE") (currently 4:00 p.m. Eastern
Time, unless weather, equipment failure or other factors contribute to an
earlier closing time) on any Business Day will be executed at the public
offering price for the applicable class of shares determined that day. A
"Business Day" is any day Monday through Friday on which the NYSE is open for
business. The minimum initial investment is $500 ($100 for IRAs and $25 for
custodial accounts under Section 403(b)(7) of the Internal Revenue Code of 1986,
as amended (the "Code"), and other tax-qualified employer-sponsored retirement
accounts, if made under a systematic investment plan providing for monthly
payments of at least that amount), and the minimum for additional purchases is
$100 ($25 for IRAs, Code Section 403 (b)(7) custodial accounts and other
tax-qualified employer-sponsored retirement accounts, as mentioned above). THE
FUND AND GT GLOBAL RESERVE THE RIGHT TO REJECT ANY PURCHASE ORDER AND TO SUSPEND
THE OFFERING OF SHARES FOR A PERIOD OF TIME. In particular, the Fund and GT
Global may reject purchase orders or exchanges by investors who appear to
follow, in the Manager's judgment, a market-timing strategy or otherwise engage
in excessive trading. See "How To Make Exchanges -- Limitations on Purchase
Orders and Exchanges."
    
 
   
WHEN PLACING PURCHASE ORDERS, INVESTORS SHOULD SPECIFY WHETHER THE ORDER IS FOR
CLASS A, CLASS B OR CLASS C SHARES OF THE FUND. ALL PURCHASE ORDERS THAT FAIL TO
SPECIFY A CLASS WILL AUTOMATICALLY BE INVESTED IN CLASS A SHARES. PURCHASES OF
$500,000 OR MORE MUST BE FOR CLASS A SHARES.
    
 
PURCHASES THROUGH BROKER/DEALERS. Shares of the Fund may be purchased through
broker/dealers with which GT Global has entered into dealer agreements. Orders
received by such broker/dealers before the close of regular trading on the NYSE
on a Business Day will be effected that day, provided that such order is
transmitted to the Transfer Agent prior to its close of business on such day.
The broker/dealer will be responsible for forwarding the investor's order to the
Transfer Agent so that it will be received prior to such time. After an initial
investment is made and a shareholder account is established through a
broker/dealer, at the investor's option subsequent purchases may be made
directly through GT Global. See "Shareholder Account Manual."
 
   
Broker/dealers that do not have dealer agreements with GT Global also may offer
to place orders for the purchase of shares. Purchases made through such
broker/dealers will be effected at the public offering price next determined
after the order is received by the Transfer Agent. Such a broker/ dealer may
charge the investor a transaction fee as determined by the broker/dealer. That
fee will be in addition to the sales charge payable by the investor, with
respect to Class A shares, and may be avoided if shares are purchased through a
broker/ dealer that has a dealer agreement with GT Global or directly through GT
Global.
    
 
PURCHASES THROUGH GT GLOBAL. Investors may purchase shares and open an account
directly through GT Global, the Fund's distributor, by completing and signing an
Account Application accompanying this Prospectus. Investors should mail to the
Transfer Agent the completed Application together with a check to cover the
purchase in accordance with the instructions provided in the Shareholder Account
Manual. Purchases will be executed at the public offering price next determined
after the Transfer Agent has received the Account Application and check.
Subsequent investments do not need to be accompanied by an application.
 
Investors also may purchase shares of the Fund through GT Global by bank wire.
Bank wire purchases will be effected at the next determined public offering
price after the bank wire is received. A wire investment is considered received
when the Transfer Agent is notified that the bank wire has been credited to the
Fund. The investor is responsible for providing prior telephonic or facsimile
notice to the Transfer Agent that a bank wire is being sent. An investor's bank
may charge a service fee for wiring money to the Fund. The Transfer Agent
currently does not charge a service fee for
 
                               Prospectus Page 13
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
facilitating wire purchases, but reserves the right to do so in the future.
Investors desiring to open an account by bank wire should call the Transfer
Agent at the appropriate toll-free number provided in the Shareholder Account
Manual to obtain an account number and detailed instructions.
 
CERTIFICATES. Physical certificates representing the Fund's shares will not be
issued unless a written request is submitted to the Transfer Agent. Shares of
the Fund are recorded on a register by the Transfer Agent, and shareholders who
do not elect to receive certificates have the same rights of ownership as if
certificates had been issued to them. Redemptions and exchanges by shareholders
who hold certificates may take longer to effect than similar transactions
involving non-certificated shares because the physical delivery and processing
of properly executed certificates is required. ACCORDINGLY, THE FUND AND GT
GLOBAL RECOMMEND THAT SHAREHOLDERS DO NOT REQUEST ISSUANCE OF CERTIFICATES.
 
   
DIFFERENCES AMONG THE CLASSES. The primary difference among the three classes of
the Fund's shares offered through this Prospectus lies in their sales charge
structures and ongoing expenses, as summarized below. Class A, Class B and Class
C shares represent the same interests in the Fund and have the same rights,
except that each class bears the separate expenses of its 12b-1 distribution
plan and has exclusive voting rights with respect to such plan, each class can
experience other minor expense differences and, in addition to different sales
charges, each class has a separate exchange privilege.
    
 
   
The decision as to which class of shares is more beneficial to an investor
depends on the amount invested, the intended length of time the investment is
held and an investor's personal situation. Large investments may qualify for a
reduced Class A sales charge. Investors in Class B shares and Class C shares
have 100% of the purchase invested immediately. Investors investing for a
relatively short period of time might consider Class C shares. Consult your
financial adviser. Broker/dealers may receive different levels of compensation
for selling a particular class of shares.
    
 
   
ADVISOR CLASS SHARES. Advisor Class shares are offered through a separate
prospectus to (a) trustees or other fiduciaries purchasing shares for employee
benefit plans that are sponsored by organizations that have at least 1,000
employees; (b) any account with assets of at least $10,000 if (i) a financial
planner, trust company, bank trust department or registered investment adviser
has investment discretion over the account, and (ii) the account holder pays
such person as compensation for its advice and other services an annual fee of
at least .50% on the assets in the account; (c) any account with assets of at
least $10,000 if (i) the account is established under a "wrap fee" program, and
(ii) the account holder pays the sponsor of the program an annual fee of at
least .50% on the assets in the account; (d) accounts advised by one of the
companies composing or affiliated with Liechtenstein Global Trust; and (e) any
of the companies composing or affiliated with Liechtenstein Global Trust.

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

only to broker/dealers that have sold or may sell significant amounts of Class A
shares. To the extent that GT Global reallows the full amount of the sales
charge to broker/dealers, such broker/dealers may be deemed to be underwriters
under the Securities Act of 1933, as amended. Commissions also may be paid to
broker/dealers and other financial institutions that initiate purchases of at
least $500,000 made pursuant to sales charge waivers (i) and (vii) described
below under "Sales Charge Waivers -- Class A Shares."
    
 
The following purchases may be aggregated for purposes of determining the
"Amount of Purchase":
 
   
(a) Individual purchases on behalf of a single purchaser, the purchaser's spouse
and their children under the age of 21 years, including purchases in connection
with an employee benefit plan or plans exclusively for the benefit of such indi-
vidual(s), such as an IRA, individual Code Section 403(b) plan or
single-participant self-employed individual retirement plan ("Keogh Plan") and
purchases made by a company controlled by such individual(s);
    
 
   
(b) Individual purchases by a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account, including an employee benefit
plan (such as employer-sponsored pension, profit-sharing and stock bonus plans,
including Code Section 401(k) plans, and medical, life and disability insurance
trusts) other than a plan described in "(a)" above; and
    
 
(c) Individual purchases by a trustee or other fiduciary purchasing shares
concurrently for two or more employee benefit plans of a single employer or of
employers affiliated with each other (again excluding an employee benefit plan
described in "(a)" above).

REINSTATEMENT PRIVILEGE. Shareholders who redeem their Class A shares in the
Fund have a onetime privilege of reinstating their investment by investing the
proceeds of the redemption at net asset value without a sales charge in Class A
shares of the Fund and/or one or more of the other GT Global Mutual Funds. The
Transfer Agent must receive from the investor or the investor's broker/ dealer
within 180 days after the date of the redemption both a written request for
reinvestment and a check not exceeding the amount of the redemption proceeds.
The reinstatement purchase will be effected at the net asset value per share
next determined after such receipt. Gain on the redemption is taxable
notwithstanding exercise of the reinvestment privilege. See "Dividends, Other
Distributions and Federal Income Taxation."
    
 
   
REDUCED SALES CHARGE PLANS -- CLASS A SHARES. Class A shares may be purchased at
reduced sales charges either through the Right of Accumulation or under a Letter
of Intent. For more details on these plans, investors should contact their
broker/ dealers or the Transfer Agent.
    
 
   
RIGHT OF ACCUMULATION. Pursuant to the Right of Accumulation, investors are
permitted to purchase shares of the Fund at the sales charge applicable to the
total of (a) the dollar amount then being purchased plus (b) the dollar amount
of the investor's concurrent purchases of other GT Global Mutual Funds (other
than GT Global Dollar Fund) plus (c) the price of all shares of GT Global Mutual
Funds (other than shares of GT Global Dollar Fund not acquired by exchange)
already held by the investor. To receive the Right of Accumulation, at the time
of purchase investors must give their broker/dealer, the Transfer Agent or GT
Global sufficient information to permit confirmation of qualification. THE
FOREGOING RIGHT OF ACCUMULATION APPLIES ONLY TO CLASS A SHARES OF THE FUND AND
OTHER GT GLOBAL MUTUAL FUNDS (OTHER THAN GT GLOBAL DOLLAR FUND).
    
 
   
LETTER OF INTENT. In executing a Letter of Intent ("LOI"), an investor indicates
an aggregate investment amount he or she intends to invest in the Class A shares
of the Fund and the Class A shares of other GT Global Mutual Funds (other than
GT Global Dollar Fund) in the following thirteen months. The LOI is included as
part of the Account Application located at the end of this Prospectus. The sales
charge applicable to that aggregate amount then becomes the applicable sales
charge on all purchases made concurrently with the execution of the LOI and in
the thirteen months following that execution. If an investor executes an LOI
within 90 days of a prior purchase of GT Global Mutual Fund Class A shares
(other than shares of GT Global Dollar Fund), the prior purchase may be included
under the LOI and an appropriate adjustment, if any, with respect to the sales
charges paid by the investor in connection with the prior purchase will be made,
based on the then-current net asset value(s) of the pertinent Fund(s).
    
 
   
If at the end of the thirteen month period covered by the LOI the total amount
of purchases does not equal the amount indicated, the investor will be required
to pay the difference between the sales charges paid at the reduced rate and the
sales charges applicable to the purchases actually made. Shares having a value
equal to 5% of the amount specified in the LOI will be held in escrow during the
thirteen month period (while remaining registered in the investor's name) and
are subject to redemption to assure any necessary payment to GT Global of a
higher applicable sales charge.
    
 
   
For purposes of an LOI, any registered investment adviser, trust company or bank
trust department which exercises investment discretion and which intends within
thirteen months to invest $500,000 or more can be treated as a single purchaser,
provided further that such entity places all purchase and redemption orders.
Such entities should be prepared to establish their qualifications for such
treatment. THE FOREGOING LOI APPLIES ONLY TO CLASS A SHARES OF THE FUND AND
OTHER GT GLOBAL MUTUAL FUNDS (OTHER THAN GT GLOBAL DOLLAR FUND).
    
 
   
CONTINGENT DEFERRED SALES CHARGE -- CLASS A SHARES. Purchases of Class A shares
of $500,000 or
    
 
                               Prospectus Page 16
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
   
more may be made without an initial sales charge. If a shareholder within one
year after the date of purchase redeems any Class A shares that were purchased
without a sales charge by reason of a purchase of $500,000 or more, a contingent
deferred sales charge of 1% of the lower of the original purchase price or the
net asset value of such shares at the time of redemption will be charged. Class
A shares will not be subject to the contingent deferred sales charge to the
extent that the value of such shares represents: (1) reinvestment of dividends
or other distributions or (2) shares redeemed more than one year after their
purchase. Such shares purchased without a sales charge may be exchanged for
Class A shares of another GT Global Mutual Fund (other than GT Global Dollar
Fund) without the imposition of a contingent deferred sales charge, although the
contingent deferred sales charge described above will apply to the redemption of
the shares acquired through an exchange. The waivers set forth under "Contingent
Deferred Sales Charge Waivers" below apply to redemptions of Class A shares upon
which a contingent deferred sales charge would otherwise be imposed. For federal
income tax purposes, the amount of the contingent deferred sales charge will
reduce the gain or increase the loss, as the case may be, realized on a
redemption. The amount of any contingent deferred sales charge will be paid to
GT Global.
    
 
                           PURCHASING CLASS B SHARES
 
   
The public offering price of the Class B shares is the next determined net asset
value per share. See "Calculation of Net Asset Value." No initial sales charge
is imposed. A contingent deferred sales charge, however, is imposed on certain
redemptions of Class B shares. Because the Class B shares are sold without an
initial sales charge, the Fund receives the full amount of the investor's
purchase payment. Class B shares may not be purchased for a Savings Incentive
Match Plan for Employees IRA ("SIMPLE IRA") for which a designated financial
institution was selected by the employer on Form 5305-SIMPLE. However, Class B
shares may be purchased for SIMPLE IRAs using Form 5304-SIMPLE. In addition,
Class A shares may be purchased for all SIMPLE IRAs.
    
 
   
Class B shares will not be subject to a contingent deferred sales charge to the
extent that the value of such shares represents: (1) reinvestment of dividends
or capital gain distributions or (2) shares redeemed more than six years after
their purchase. Redemptions of most other Class B shares will be subject to a
contingent deferred sales charge. See "Contingent Deferred Sales Charge
Waivers." The amount of any applicable contingent deferred sales charge will be
calculated by multiplying the lesser of the original purchase price or the net
asset value of such shares at the time of redemption by the applicable
percentage shown in the table below.

</TABLE>
 
In determining whether a contingent deferred sales charge is applicable, it will
be assumed that the redemption is made first of shares acquired pursuant to the
reinvestment of dividends and other distributions; then of shares purchased
seven years or more prior to the redemption; and finally, of shares held for the
longest period of time within the applicable six-year period. For shares
acquired in an exchange, the length of the holding period will be measured from
the date of original purchase.
 
For example, assume an investor purchased 100 shares at $10 per share for a cost
of $1,000. Subsequently, the shareholder acquired 15 additional shares through
dividend reinvestment. During the second year after the purchase the investor
decided to redeem $500 of his or her investment. Assuming at the time of the
redemption a net asset value of $11 per share, the value of the investor's
shares would be $1,265 (115 shares at $11 per share). The contingent deferred
sales charge would not be applied to the value of the reinvested dividend
shares. Therefore, the 15 shares currently valued at $165.00 would be redeemed
without a contingent deferred sales charge. The number of shares needed to fund
the remaining $335 of the redemption would equal 30.455. Using the lower of cost
or market price to determine the contingent deferred sales charge, the original
purchase price of $10.00 per share would be used. The contingent deferred sales
charge calculation would therefore be 30.455 shares times $10.00 per share at
the contingent deferred sales charge rate of 4% (the applicable rate in the
second year after purchase) for a total contingent deferred sales charge of
$12.18.

tender offer by GT

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
   
Global Floating Rate Fund, Inc. ("Floating Rate Fund") will be subject, in lieu
of the contingent deferred sales charge described above, to a contingent
deferred sales charge equivalent to the early withdrawal charge on the common
stock of the Floating Rate Fund. The purchase of Class B shares of the Fund will
be deemed to have occurred at the time of the initial purchase of the Floating
Rate Fund's common stock.
    
 
   
For federal income tax purposes, the amount of the contingent deferred sales
charge will reduce the gain or increase the loss, as the case may be, realized
on a redemption. See "Purchasing Class A Shares -- Reinstatement Privilege." The
amount of any contingent deferred sales charge will be paid to GT Global.
    
 
   
                          CONVERSION OF CLASS B SHARES
    
 
   
Class B shares automatically will convert to Class A shares eight years from the
end of the calendar month in which the shareholder's order to purchase was
accepted. The conversion will be affected at the relative net asset value per
share of each class. At the time of conversion, a portion of Class B shares
purchased through reinvestment of dividends or other distributions ("Dividend
Shares") also will convert to Class A shares. The portion of Dividend Shares
that will convert is determined by the ratio of converting Class B non-Dividend
Shares to the total Class B non-Dividend Shares held by the shareholder.
    
 
   
                           PURCHASING CLASS C SHARES
    
 
   
The public offering price of the Class C shares of the Fund is the next
determined net asset value per share. See "Calculation of Net Asset Value." No
initial sales charge is imposed. A contingent deferred sales charge, however, is
charged on shares sold within one year of purchase. Because the Class C shares
are sold without an initial sales charge, the Fund receives the full amount of
the investor's purchase payment. Class C shares of the Fund may not be purchased
for a SIMPLE IRA for which a designated financial institution was selected by
the employer on Form 5305-SIMPLE. However, Class C shares of the Fund may be
purchased for SIMPLE IRAs using Form 5304-SIMPLE. In addition, Class A shares
may be purchased for all SIMPLE IRAs.
    
 
   
Purchases of Class C shares may be made without an initial sales charge. If sold
within one year of purchase, a contingent deferred sales charge of 1% of the
lower of the original purchase price or the net asset value of such shares at
the time sold will be charged. Class C shares will not be subject to the
contingent deferred sales charge to the extent that the value of such shares
represents: (1) reinvestment of dividends or other distributions or (2) shares
redeemed more than one year after their purchase. Redemptions of most other
Class C shares will be subject to a contingent deferred sales charge. See
"Contingent Deferred Sales Charge Waivers." For federal income tax purposes, the
amount of the contingent deferred sales charge will reduce the gain or increase
the loss, as the case may be, realized on a redemption. The amount of any
contingent deferred sales charge will be paid to GT Global.

                              SALES CHARGE WAIVERS
    
 
   
The contingent deferred sales charge applicable to Class A, Class B or Class C
shares will be waived for (1) exchanges, as described below; (2) redemptions in
connection with the Fund's systematic withdrawal plan not in excess of 12% of
the value of the account annually; (3) total or partial redemptions made within
one year following the death or disability of a shareholder; (4) minimum
required distributions made in connection with a GT Global IRA, Keogh Plan or
custodial account under Section 403(b) of the Code or other retirement plan
following attainment of age 70 1/2; (5) total or partial redemptions resulting
from a distribution following retirement in the case of a tax-qualified
employer-sponsored retirement plan; (6) when a redemption results from a
tax-free return of an excess contribution pursuant to Section 408(d)(4) or (5)
of the Code or from the death or disability of the employee; (7) a one-time
reinvestment in Class B shares of the Fund within 180 days of a prior
redemption; (8) redemptions pursuant to the Fund's right to liquidate a
shareholder's account involuntarily; (9) redemptions pursuant to a distribution
from a tax-qualified employer-sponsored retirement plan, which is invested in GT
Global Mutual Funds, that is permitted to be made without penalty pursuant to
the Code, other than tax-free rollovers or transfers of assets, and the proceeds
of which are reinvested in GT Global Mutual Funds; (10) redemptions made in
connection with participant-directed exchanges between options in an
employer-sponsored benefit plan; (11) redemptions made for the purpose of
providing cash to fund a loan to a participant in a tax-qualified retirement
plan; (12) redemptions made in

connection with a distribution from any retirement plan or account that is
permitted in accordance with the provisions of Section 72(t)(2) of the Code and
the regulations promulgated thereunder; (13) redemptions made in connection with
a distribution from any retirement plan or account that involves the return of
an excess deferral amount pursuant to Sections 401(k)(8) or 402(g)(2) of the
Code or the return of excess aggregate contributions pursuant to Section
401(m)(6) of the Code; (14) redemptions made in connection with a distribution
from a qualified profit-sharing or stock bonus plan described in Section 401(k)
of the Code to a participant or beneficiary under Section 401(k)(2)(B)(IV) of
the Code upon hardship of the covered employee (determined pursuant to Treasury
Regulation Section 1.401(k)-1(d)(2)); and (15) redemptions made by or for the
benefit of certain states, counties or cities, or any instrumentalities,
departments or authorities thereof where such entities are prohibited or limited
by applicable law from paying a sales charge or commission.
    
 
   
           PROGRAMS APPLICABLE TO CLASS A, CLASS B AND CLASS C SHARES
    
 
   
AUTOMATIC INVESTMENT PLAN. Investors may purchase either Class A, Class B or
Class C shares of the Fund through the GT Global Automatic Investment Plan.
Under this Plan, an amount specified by the shareholder of $100 or more ($25 or
more for IRAs, Code Section 403(b)(7) custodial accounts and other tax-qualified
employer-sponsored retirement accounts) on a monthly or quarterly basis will be
sent to the Transfer Agent from the investor's bank for investment in the Fund.
Participants in the Automatic Investment Plan should not elect to receive
dividends or other distributions from the Fund in cash. A sales charge will be
applied to each automatic monthly purchase of Class A shares in an amount
determined in accordance with the Right of Accumulation privilege described
above. To participate in the Automatic Investment Plan, investors should
complete the appropriate portion of the Supplemental Application provided at the
end of this Prospectus. Investors should contact their brokers or GT Global for
more information.
    
 
   
DOLLAR COST AVERAGING PROGRAM. Investors may purchase either Class A, Class B or
Class C shares of the Fund through the GT Global Dollar Cost Averaging Program
whereby a shareholder invests the same dollar amount each month. Accordingly,
the investor purchases more shares when the Fund's net asset value is relatively
low and fewer shares when the Fund's net asset value is relatively high. This
can result in a lower average cost-per-share than if the shareholder followed a
less systematic approach. Dollar cost averaging does not assure a profit and
does not protect against loss in declining markets. Because such a program
involves continuous investment in securities regardless of fluctuating price
levels of such securities, investors should consider their financial ability to
continue purchases when prices are declining.
    
 
   
A participant in the GT Global Dollar Cost Averaging Program first designates
the size of his or her monthly investment in the Fund ("Monthly Investment")
after participation in the Program begins. The Monthly Investment must be at
least $1,000. The investor then will make an initial investment of at least
$10,000 in the GT Global Dollar Fund. Thereafter, each month an amount equal to
the specified Monthly Investment automatically will be redeemed from the GT
Global Dollar Fund and invested in Fund shares. A sales charge will be applied
to each automatic monthly purchase of Class A shares of the Fund in an amount
determined in accordance with the Right of Accumulation privilege described
above. Investors should contact their brokers or GT Global for more information.
    
 
   
PORTFOLIO REBALANCING PROGRAM. The GT Global Portfolio Rebalancing Program
("Program") permits eligible shareholders to establish and maintain an
allocation across a range of GT Global Mutual Funds. The Program automatically
rebalances holdings of GT Global Mutual Funds to the established allocation on a
periodic basis. Under the Program, a shareholder may predesignate, on a
percentage basis, how the total value of his or her holdings in a minimum of
two, and a maximum of ten, GT Global Mutual Funds ("Personal Portfolio") is to
be rebalanced on a monthly, quarterly, semiannual, or annual basis.
    
 
Rebalancing under the Program will be effected through the exchange of shares of
one or more GT Global Mutual Funds in the shareholder's Personal Portfolio for
shares of the same class(es) of one or more other GT Global Mutual Funds in the
shareholder's Personal Portfolio. See "How to Make Exchanges." If shares of the
GT Global Mutual Funds in a shareholder's Personal Portfolio have appreciated
during a rebalancing period, the Program will result in shares of GT Global
Mutual Fund(s) that have appreciated most during the period being exchanged for
shares of GT Global
 
                               Prospectus Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Mutual Fund(s) that have appreciated least. SUCH EXCHANGES ARE NOT TAX-FREE AND
MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR LOSS, AS THE CASE MAY BE, FOR
FEDERAL INCOME TAX PURPOSES. See "Dividends, Other Distributions and Federal
Income Taxation." Participation in the Program does not assure that a
shareholder will profit from purchases under the Program, nor does it prevent or
lessen losses in a declining market.
 
   
The Program will automatically rebalance the shareholder's Personal Portfolio on
the 28th day of the last month of the period chosen (or the immediately
preceding business day if the 28th is not a business day), subject to any
limitations below. The Program will not execute an exchange if the variance in a
shareholder's Personal Portfolio for a particular Fund would be 2% or less. In
predesignating percentages, shareholders must use whole percentages and totals
must equal 100%. Shareholders participating in the Program may not request
issuance of physical certificates representing a Fund's shares. Exchanges made
under the Program are not subject to the four free exchanges per year
limitation. The Funds and GT Global reserve the right to modify, suspend, or
terminate the Program at any time on 60 days' prior written notice to
shareholders. A request to participate in the Program must be received in good
order at least five business days prior to the next rebalancing date. Once a
shareholder establishes the Program for his or her Personal Portfolio, a
shareholder cannot cancel or change which rebalancing frequency, which Funds or
what allocation percentages are assigned to the Program, unless canceled or
changed in writing and received by the Transfer Agent in good order at least
five business days prior to the rebalancing date. Shareholders participating in
the Program may also participate in the Right of Accumulation, Letter of Intent,
and Dollar Cost Averaging programs. Certain broker/dealers may charge a fee for
establishing accounts relating to the Program. Investors should contact their
broker/dealers or GT Global for more information.

                             HOW TO MAKE EXCHANGES
 
- --------------------------------------------------------------------------------
 
   
Shares of the Fund may be exchanged for shares of the same class of any other GT
Global Mutual Fund based on their respective net asset values without imposition
of any sales charges, provided that the registration remains identical.
EXCHANGES ARE NOT TAX-FREE AND MAY RESULT IN A SHAREHOLDER'S REALIZING A GAIN OR
LOSS, AS THE CASE MAY BE, FOR FEDERAL INCOME TAX PURPOSES. See "Dividends, Other
Distributions and Federal Income Taxation." The exchange of Class B or Class C
shares will not be subject to a contingent deferred sales charge. For purposes
of computing the contingent deferred sales charge, the length of time of
ownership of Class B or Class C shares will be measured from the date of
original purchase and will not be affected by the exchange. In addition to the
Fund, the GT Global Mutual Funds currently include:
    
   -- GT GLOBAL WORLDWIDE GROWTH FUND
   -- GT GLOBAL INTERNATIONAL GROWTH FUND
   -- GT GLOBAL EMERGING MARKETS FUND
   -- GT GLOBAL NEW PACIFIC GROWTH FUND
   -- GT GLOBAL EUROPE GROWTH FUND
   -- GT GLOBAL LATIN AMERICA GROWTH FUND
   -- GT GLOBAL AMERICA SMALL CAP GROWTH FUND
   -- GT GLOBAL AMERICA MID CAP GROWTH FUND
   -- GT GLOBAL AMERICA VALUE FUND
   -- GT GLOBAL JAPAN GROWTH FUND
   -- GT GLOBAL GROWTH & INCOME FUND
   -- GT GLOBAL GOVERNMENT INCOME FUND
   -- GT GLOBAL STRATEGIC INCOME FUND
   -- GT GLOBAL HIGH INCOME FUND
   -- GT GLOBAL DOLLAR FUND
   -- GT GLOBAL CONSUMER PRODUCTS AND
       SERVICES FUND
   -- GT GLOBAL FINANCIAL SERVICES FUND
   -- GT GLOBAL HEALTH CARE FUND
   -- GT GLOBAL INFRASTRUCTURE FUND
   -- GT GLOBAL NATURAL RESOURCES FUND
   -- GT GLOBAL TELECOMMUNICATIONS FUND
 
   
Exchange privileges for Class C shares will not be available until other GT
Global Mutual Funds commence offering Class C shares which is expected to occur
on or about March 1, 1998.
    
 
Up to four exchanges each year may be made without charge. A $7.50 service
charge will be imposed on each subsequent exchange. If an investor does not
surrender all of his or her shares in an exchange, the remaining balance in the
investor's account after the exchange must be at least $500. Exchange requests
received in good order by the Transfer Agent before the close of regular trading
on the NYSE on any Business Day will be processed at the net asset value
calculated on that day. The terms of the exchange offer may be modified at any
time, on 60 days' prior written notice.
 
An investor interested in making an exchange should write or call his or her
broker/dealer or the Transfer Agent to request the prospectus of the other GT
Global Mutual Fund(s) being considered. Certain broker/dealers may charge a fee
for handling exchanges.
 
EXCHANGES BY TELEPHONE. A shareholder may give exchange instructions to the
shareholder's broker/ dealer or the Transfer Agent by telephone at the
appropriate toll-free number provided in the Shareholder Account Manual.
Exchange orders will be accepted by telephone provided that the exchange
involves only uncertificated shares on deposit in the shareholder's account or
for which certificates have previously been deposited. Shareholders
automatically have telephone privileges to authorize exchanges. The Fund, GT
Global and the Transfer Agent will not be liable for any loss or damage for
acting in good faith upon instructions received by telephone and reasonably
believed to be genuine. The Fund employs reasonable procedures to confirm that
instructions communicated by telephone are genuine prior to acting upon
instructions received by telephone, including requiring some form of personal
identification, providing written confirmation of such transactions, and/or tape
recording of telephone instructions.
 
EXCHANGES BY MAIL. Exchange orders should be sent by mail to the investor's
broker/dealer or to the Transfer Agent at the address set forth in the
Shareholder Account Manual.
 
LIMITATIONS ON PURCHASE ORDERS AND EXCHANGES. The GT Global Mutual Funds are not
intended to serve as vehicles for frequent trading in response to short-term
fluctuations in the market. Due to the disruptive effect that market-timing
investment strategies and excessive trading can have on efficient portfolio
management, each GT Global Mutual Fund and GT Global reserve the right to refuse
purchase orders and exchanges by any person or group, if, in the Manager's
judgment, such person or group was following a market-timing strategy or was
otherwise engaging in excessive trading.
 
In addition, each GT Global Mutual Fund and GT Global reserve the right to
refuse purchase orders and exchanges by any person or group if, in the Manager's
judgment, the Fund would not be able to invest the money effectively in
accordance with that Fund's investment objective and policies or would otherwise
potentially be adversely affected. Although a GT Global Mutual Fund will attempt
to give investors prior notice whenever it is reasonably able to do so, it may
impose the above restrictions at any time.
 
Finally, as described above, each GT Global Mutual Fund and GT Global reserve
the right to reject any purchase order.

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

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Global and the Transfer Agent will not be liable for any loss or damage for
acting in good faith upon instructions received by telephone and reasonably
believed to be genuine. The Fund employs reasonable procedures to confirm that
instructions communicated by telephone are genuine prior to acting upon
instructions received by telephone, including requiring some form of personal
identification providing written confirmation of such transactions, and/or tape
recording of telephone instructions.
 
REDEMPTIONS BY MAIL. Redemption requests should be mailed directly to the
Transfer Agent at the appropriate address provided in the Shareholder Account
Manual. As discussed above, requests for payment of redemption proceeds to a
party other than the shareholder of record and/or requests that redemption
proceeds be mailed to an address other than the shareholder's address of record
require a signature guarantee. In addition, if the shareholder's address of
record has been changed within the preceding thirty days, a signature guarantee
is required. Redemptions of shares for which certificates have been issued must
be accompanied by properly endorsed share certificates.
 
   
SYSTEMATIC WITHDRAWAL PLAN. Shareholders owning shares with a value of $10,000
or more may participate in the GT Global Systematic Withdrawal Plan. A
participating shareholder will receive proceeds from monthly, quarterly or
annual redemptions of Fund shares with respect to either Class A, Class B or
Class C shares. No contingent deferred sales charge will be imposed on
redemptions made under the Systematic Withdrawal Plan. The minimum withdrawal
amount is $100. The amount or percentage a participating shareholder specifies
to be redeemed may not, on an annualized basis, exceed 12% of the value of the
account, as of the time the shareholder elects to participate in the Systematic
Withdrawal Plan. To participate in the Systematic Withdrawal Plan, investors
should complete the appropriate portion of the Supplemental Application provided
at the end of this Prospectus. Investors should contact their broker/dealers or
the Transfer Agent for more information. With respect to Class A shares,
participation in the Systematic Withdrawal Plan concurrent with purchases of
Class A shares may be disadvantageous to investors because of the sales charges
involved and possible tax implications, and therefore is discouraged. In
addition, shareholders who participate in the Systematic Withdrawal Plan should
not elect to reinvest dividends or other distributions in additional Fund
shares.
    
 
OTHER IMPORTANT REDEMPTION INFORMATION. A request for redemption will not be
processed until all of the necessary documentation has been received in good
order. A shareholder in doubt as to what documents are required should contact
his or her broker/dealer or the Transfer Agent.
 
Except in extraordinary circumstances and as permitted under the 1940 Act,
payment for shares redeemed by telephone or by mail will be made promptly after
receipt of a redemption request, if in good order, but not later than seven days
after the date the request is executed. Requests for redemption which are
subject to any special conditions or which specify a future or past effective
date cannot be accepted.
 
If the Transfer Agent is requested to redeem shares for which the Fund has not
yet received good payment, the Fund may delay payment of redemption proceeds
until the Transfer Agent has assured itself that good payment has been collected
for the purchase of the shares. In the case of purchases by check it can take up
to 10 business days to confirm that the check has cleared and good payment has
been received. Redemption proceeds will not be delayed when shares have been
paid for by wire or when the investor's account holds a sufficient number of
shares for which funds already have been collected.
 
The Fund may redeem the shares of any shareholder whose account is reduced to
less than $500 in value through redemptions or other action by the shareholder.
Written notice will be given to the shareholder at least 60 days prior to the
date fixed for such redemption, during which time the shareholder may increase
his or her holdings to an aggregate amount of $500 or more (with a minimum
purchase of $100).

                          GT GLOBAL NEW DIMENSION FUND
 
                         CALCULATION OF NET ASSET VALUE
 
- --------------------------------------------------------------------------------
 
The Fund calculates its net asset value as of the close of regular trading on
the NYSE (currently 4:00 p.m. Eastern Time, unless weather, equipment failure or
other factors contribute to an earlier closing time) each Business Day. The
Fund's net asset value per share is computed by dividing the value of the Fund's
net assets by the total number of Fund shares outstanding. Net asset value is
determined separately for each class of shares of the Fund. The assets of the
Fund consist primarily of shares of the Underlying Theme Funds, which are valued
daily at their respective net asset values at the time of computation. Other
Fund assets are valued at current market price or, if unavailable, at fair value
determined in good faith by or under the direction of the Trust's Board of
Trustees.
 
   
The different service and distribution fees borne by each class of shares of the
Fund will result in different net asset values and dividends. The per share net
asset value of the Class B and Class C shares generally will be lower than that
of the Class A shares because of the higher service and distribution fees borne
by the Class B and Class C shares. The per share net asset value of the Advisor
Class shares generally will be higher than that of the Class A, Class B and
Class C shares because of the absence of any service and distribution fees
applicable to the Advisor Class shares. It is expected, however, that the net
asset value per share of the classes will tend to converge immediately after the
payment of dividends, which will differ by approximately the amount of the
service and distribution fee accrual differential among the classes.
    
 
- --------------------------------------------------------------------------------
 
                         DIVIDENDS, OTHER DISTRIBUTIONS
                          AND FEDERAL INCOME TAXATION
 
- --------------------------------------------------------------------------------
 
DIVIDENDS AND OTHER DISTRIBUTIONS. The Fund annually declares and pays as a
dividend all of its net investment income, if any, which includes dividends paid
to it from each Underlying Theme Fund's net investment income (if any) less
applicable expenses. The Fund also annually distributes substantially all of its
realized net capital gains, if any, which consist of (1) distributions to it
from each Underlying Theme Fund's realized net capital gains, if any, and (2)
net gains realized from the Fund's disposition of shares of the Underlying Theme
Funds (which dispositions generally are occasioned by reallocating the Fund's
assets among the Underlying Theme Funds to reflect the MCSI weightings (see
"Investment Objective and Policies") or by the need to make distributions and/
or payments of redemption proceeds in excess of available cash). The Fund may
make an additional dividend or other distribution if necessary to avoid a 4%
excise tax on certain undistributed income and gain.
 
   
Dividends and other distributions paid by the Fund with respect to all classes
of its shares are calculated in the same manner and at the same time. The per
share income dividends on Class B and Class C shares will be lower than the per
share income dividends on Class A shares as a result of the higher service and
distribution fees applicable to Class B and Class C shares; and the per share
income dividends on such classes of shares will be lower than the per share
income dividends on the Advisor Class shares of the Fund as a result of the
absence of any service and distribution fees applicable to Advisor Class shares.
SHAREHOLDERS MAY ELECT:
    
 
/ / to have all dividends and other distributions automatically reinvested in
    additional Fund shares of the distributing class (or in shares of the
    corresponding class of other GT Global Mutual Funds); or
 
/ / to receive dividends in cash and have other distributions automatically
    reinvested in additional Fund shares of the distributing class (or in shares
    of the corresponding class of other GT Global Mutual Funds); or
 
                               Prospectus Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
/ / to receive other distributions in cash and have dividends automatically
    reinvested in additional Fund shares of the distributing class (or in shares
    of the corresponding class of other GT Global Mutual Funds); or
 
/ / to receive dividends and other distributions in cash.
 
Automatic reinvestments in additional shares are made at net asset value without
imposition of a sales charge. IF NO ELECTION IS MADE BY A SHAREHOLDER, ALL
DIVIDENDS AND OTHER DISTRIBUTIONS WILL BE AUTOMATICALLY REINVESTED IN ADDITIONAL
FUND SHARES OF THE DISTRIBUTING CLASS. Reinvestments in another GT Global Mutual
Fund may only be directed to an account with the identical shareholder
registration and account number. These elections may be changed by a shareholder
at any time; to be effective with respect to a distribution, the shareholder or
the shareholder's broker must contact the Transfer Agent by mail or telephone at
least 15 Business Days prior to the payment date. THE FEDERAL INCOME TAX
CONSEQUENCES OF DIVIDENDS AND OTHER DISTRIBUTIONS ARE THE SAME WHETHER THEY ARE
RECEIVED IN CASH OR REINVESTED IN ADDITIONAL SHARES.
 
Any dividend or other distribution paid by the Fund has the effect of reducing
the net asset value per share on the ex-distribution date by the amount thereof.
Therefore, a dividend or other distribution paid shortly after a purchase of
shares would represent, in substance, a return of capital to the shareholder (to
the extent the distribution is paid on the shares so purchased) even though
subject to income tax, as discussed below.
 
   
TAXES. The Fund intends to continue to qualify for treatment as a regulated
investment company under the Code. In each taxable year that the Fund so
qualifies, the Fund (but not its shareholders) will be relieved of federal
income tax on that part of its investment company taxable income, consisting
generally of net investment income and net short-term capital gain ("taxable
income"), and net capital gain (i.e., the excess of net long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.
    
 
   
Dividends paid to the Fund from an Underlying Theme Fund's taxable income (which
may include net gains from certain foreign currency transactions) are included
in the Fund's taxable income, and dividends from the latter (whether paid in
cash or reinvested in additional shares) are taxable to the Fund's shareholders
as ordinary income to the extent of its earnings and profits. Distributions of
the Fund's net capital gain (consisting of (1) distributions to it from each
Underlying Theme Fund's net capital gain, when designated as such, and (2) net
gains realized from the Fund's disposition of an Underlying Theme Fund's shares
held for more than twelve months), when designated as such, are taxable to its
shareholders as long-term capital gains, regardless of how long they have held
their Fund shares and whether the distributions are paid in cash or reinvested
in additional shares.
    
 
   
The Fund provides federal tax information to its shareholders annually,
including information about dividends and capital gain distributions paid during
the preceding year.
    
 
   
The information regarding capital gain distributions designates the portions of
those distributions that are subject to (1) the 20% maximum rate of tax (10% for
investors in the 15% marginal tax bracket) enacted by the Taxpayer Relief Act of
1997 ("Tax Act"), which applies to gain on securities held for more than 18
months, and (2) the 28% maximum tax rate, applicable to gain on securities held
for more than 12 and up to 18 months (which, prior to enactment of the Tax Act,
applied to all capital gain on securities held for more than one year).
    
 
The Fund must withhold 31% from dividends, capital gain distributions and
redemption proceeds payable to any individuals and certain other noncorporate
shareholders who have not furnished to the Fund a correct taxpayer
identification number or a properly completed claim for exemption on Form W-8 or
W-9. Withholding at that rate also is required from dividends and capital gain
distributions payable to such shareholders who otherwise are subject to backup
withholding. Fund accounts opened via a bank wire purchase (see "How to Invest
- -- Purchases Through the Distributor") are considered to have uncertified
taxpayer identification numbers unless a completed Form W-8 or W-9 or Account
Application is received by the Transfer Agent within seven days after the
purchase. A shareholder should contact the Transfer Agent if the shareholder is
uncertain whether a proper taxpayer identification number is on file with the
Fund.
 
A redemption of Fund shares may result in taxable gain or loss to the redeeming
shareholder, depending upon whether the redemption proceeds are more or less
than the shareholder's adjusted basis for the redeemed shares (which normally
includes any initial sales charge paid on Class A shares). An exchange of Fund
shares for shares of
 
                               Prospectus Page 26
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
another GT Global Mutual Fund generally will have similar tax consequences.
However, special tax rules apply when a shareholder (1) disposes of Class A
shares of the Fund through a redemption or exchange within 90 days after
purchase and (2) subsequently acquires Class A shares of the Fund or of any
other GT Global Mutual Fund on which an initial sales charge normally is imposed
without paying that sales charge due to the reinstatement privilege or exchange
privilege. In these cases, any gain on the disposition of the original Class A
shares will be increased, or loss decreased, by the amount of the sales charge
paid when those shares were acquired, and that amount will increase the adjusted
basis of the shares subsequently acquired. In addition, if Fund shares are
purchased within 30 days before or after redeeming other Fund shares (regardless
of class) at a loss, all or a part of the loss will not be deductible and
instead will increase the basis of the newly purchased shares.
 
The foregoing is only a summary of some of the important federal tax
considerations generally affecting the Fund and its shareholders. See "Taxes" in
the Statement of Additional Information for a further discussion. There may be
other federal, state, local or foreign tax considerations applicable to a
particular investor. Prospective investors therefore are urged to consult their
tax advisers.

                                   MANAGEMENT
 
- --------------------------------------------------------------------------------
 
The Trust's Board of Trustees has overall responsibility for the operation of
the Fund and has approved contracts with various financial organizations to
provide certain services required by the Fund. See "Trustees and Executive
Officers" in the Statement of Additional Information for a complete description
of the Trustees of the Trust.
 
INVESTMENT MANAGEMENT AND ADMINISTRATION. Subject to the supervision and
direction of the Trust's Board of Trustees, the Manager will ensure that the
Fund's assets are invested in the Underlying Theme Funds according to the
formula and pre-determined percentages described in the "Investment Objective
and Policies" section of this Prospectus. The Manager will determine how the
Fund's assets will be invested in short-term investments and place all purchase
and sale orders for such instruments and for the Underlying Theme Funds. The
Manager provides the following administration services to the Fund: furnishing
corporate officers and clerical staff; providing office space, services and
equipment; and supervising all matters relating to the Fund's operation. The
Manager also serves as the Fund's pricing and accounting agent. Finally, the
Manager will initially assume all costs of the Fund's operation, except for
service and distribution fees described below and non-recurring and
extraordinary expenses. The Fund, as a shareholder in the Underlying Theme
Funds, indirectly will bear its proportionate share of any investment management
fees and other expenses paid by the Underlying Theme Funds.
 
The Manager provides investment management and/or administration services to the
GT Global Mutual Funds. The Manager and its worldwide asset management
affiliates have provided investment management and/or administration services to
institutional, corporate and individual clients around the world since 1969. The
U.S. offices of the Manager are located at 50 California street, 27th Floor, San
Francisco, CA 94111 and 1166 Avenue of the Americas, New York, NY 10036.
 
The Manager and its worldwide affiliates, including LGT Bank in Liechtenstein,
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
 
                               Prospectus Page 27
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 Fund's assets
among the Underlying Theme Funds according to the MSCI weighting as of the last
business day of the preceding month.
    
 
   
DISTRIBUTION OF FUND SHARES. GT Global is the distributor of the Fund's Class A,
Class B and Class C shares. Like the Manager, GT Global is a subsidiary of
Liechtenstein Global Trust with offices at 50 California Street, 27th Floor, San
Francisco, CA 94111. As distributor, GT Global collects the sales charges
imposed on purchases of Class A shares and any contingent deferred sales charges
that may be imposed on certain redemptions of Class A, Class B and Class C
shares. GT Global reallows a portion of the sales charge on Class A shares to
broker/dealers that have sold such shares in accordance with the schedule set
forth above under "How to Invest." GT Global also pays a commission equal to
4.00% of the amount invested to broker/ dealers who sell Class B shares and pays
a commission equal to 1.00% of the amount invested to broker/dealers who sell
Class C shares. A commission is not paid on exchanges or certain reinvestments
in Class B or Class C shares. In addition, with respect to all three classes of
shares, GT Global makes ongoing payments to broker/ dealers for distribution and
service activities in accordance with the Rule 12b-1 plans described below.
    
 
GT Global, at its own expense, may provide additional promotional incentives to
broker/dealers that sell shares of the Fund and/or shares of the other GT Global
Mutual Funds. In some instances additional compensation or promotional
incentives may be offered to broker/dealers that have sold or may sell
significant amounts of shares during specified periods of time. Such
compensation and incentives may include, but are not limited to, cash,
merchandise, trips and financial assistance to broker/dealers in connection with
preapproved conferences or seminars, sales or training programs for invited
sales personnel, payment for travel expenses (including meals and lodging)
incurred by sales personnel and members of their families or other invited
guests to various locations for such seminars or training programs, seminars for
the public, advertising and sales campaigns regarding one or more of the GT
Global Mutual Funds, and/ or other events sponsored by the broker/dealers. In
addition, GT Global makes ongoing payments to brokerage firms, financial
institutions (including banks) and others that facilitate the administration and
servicing of shareholder accounts.
 
Under a plan of distribution adopted by the Trust's Board of Trustees pursuant
to Rule 12b-1 under the 1940 Act, with respect to the Fund's Class A shares
("Class A Plan"), the Fund may pay GT Global a service fee at the annualized
rate of up to 0.25% of the average daily net assets of the Fund's Class A shares
for its expenditures incurred in servicing and maintaining shareholder accounts,
and may pay GT Global a distribution fee at the annualized rate of up to 0.50%
of the average daily net assets of the Fund's Class A shares, less any amounts
paid by the Fund as the aforementioned service fee for its expenditures incurred
in providing services as distributor. All expenses for which GT Global is
reimbursed under the Class A Plan will have been incurred within one year of
such reimbursement.
 
   
Pursuant to separate plans of distribution adopted with respect to the Fund's
Class B and Class C shares ("Class B Plan" and "Class C Plan," respectively),
the Fund may pay GT Global a service fee at the annualized rate of up to 0.25%
of the average daily net assets of the Fund's Class B and Class C shares for its
expenditures incurred in servicing and maintaining shareholder accounts, and may
pay GT Global a distribution fee at the annualized rate of up to 0.75% of the
average daily net assets of the Fund's Class B and Class C shares for its
expenditures incurred in providing services as distributor. Expenses incurred
under the Class B Plan and Class C Plan in excess of 1.00% annually may be
carried forward for reimbursement in

                          GT GLOBAL NEW DIMENSION FUND
subsequent years as long as such Plan continues in effect.
 
   
GT Global's service and distribution expenses include the payment of ongoing
commissions; the cost of any additional compensation paid by GT Global to
broker/dealers; the costs of printing and mailing to prospective investors
prospectuses and other materials relating to the Funds; the costs of developing,
printing, distributing and publishing advertisements and other sales literature;
and allocated costs relating to GT Global's distribution activities, including,
among other things, employee salaries, bonuses and other overhead expenses. In
addition, its expenses under the Class B Plan and the Class C Plan include
payment of initial sales commissions to broker/ dealers and interest on any
unreimbursed amounts carried forward thereunder.
    
 
The Glass-Steagall Act and other applicable laws, among other things, generally
prohibit federally chartered or supervised banks from engaging in the business
of underwriting or distributing securities. Accordingly, GT Global intends to
engage banks (if at all) only to perform administrative and shareholder
servicing functions. If a bank were prohibited from so acting, its shareholder
clients would be permitted to remain shareholders, and alternative means for
continuing the servicing of such shareholders would be sought. It is not
expected that shareholders would suffer any adverse financial consequences as a
result of any of these occurrences.

                               OTHER INFORMATION
 
- --------------------------------------------------------------------------------
 
SPECIAL SERVICING AGREEMENT. Until the Special Servicing Agreement described
below is entered into, the Manager will pay all the expenses of the Fund,
excluding service and distribution fees and certain non-recurring and
extraordinary expenses. Expenses initially paid by the Manager will include fees
and expenses 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 requested from
the Internal Revenue Service concerning this arrangement. If relief is obtained,
all the Fund's expenses except for service and distribution fees and certain
non-recurring and extraordinary expenses will be paid for in accordance with the
Agreement. Under the Agreement, to the extent that the aggregate expenses of the
Fund are less than the estimated savings to the Underlying Theme Funds from the
operation of the Fund, each Underlying Theme Fund will bear those expenses in
proportion to the average daily value of its shares owned by the Fund and/or the
number of shareholder accounts at the Fund. The estimated savings are expected
to result from the reduction of the Underlying Theme Funds' shareholder
servicing costs due to the elimination of separate shareholder accounts that
either currently are or have potential to be invested in the Underlying Theme
Funds. The estimated savings produced by the operation of the Fund may offset
most, if not all, the expenses incurred by the Fund other than service and
distribution fees. To the extent that the Fund's expenses exceed the aggregate
financial benefits to the Underlying Theme Funds, the Manager will pay that
excess.
    
 
CONFIRMATIONS AND REPORTS TO SHAREHOLDERS. Each time a transaction is made that
affects a shareholder's account in the Fund, the shareholder will receive from
the Transfer Agent a confirmation statement reflecting the transaction.
Confirmations for transactions effected pursuant to the Fund's Automatic
Investment Plan, Systematic Withdrawal Plan and automatic dividend reinvestment
program may be provided quarterly. Shortly after the end of the Fund's fiscal
year on December 31 and fiscal half-year on June 30 of each year, shareholders
receive an annual and semiannual report, respectively. In addition, the federal
income status of distributions made by the Fund to shareholders is reported
after the end of each calendar

year on Form 1099-DIV. Under certain circumstances, duplicate mailings of the
foregoing reports to the same household may be consolidated.
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Massachusetts business
trust on August 26, 1996. The Trust currently consists of one series. From time
to time, the Trust may establish other series, each holding a distinct
investment portfolio and issuing a distinct series of the Trust's shares. Shares
of each series are entitled to one vote per share (with proportional voting for
fractional shares) and are transferable. Shareholders have no preemptive or
conversion rights.
    
 
   
If any additional series of the Trust are established, on any matter submitted
to a vote of shareholders, shares of each series will be voted by its
shareholders individually when the matter affects the specific interest of that
series only, such as approval of its investment management arrangements. The
shares of the Trust's series would be voted in the aggregate on other matters,
such as the election of Trustees and ratification of the selection by the Board
of Trustees of the Trust's independent accountants.
    
 
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. The Fund would be required to hold a shareholders'
meeting if at any time less than a majority of the Trustees holding office had
been elected by shareholders. Trustees continue to hold office until their
successors are elected and have qualified. Fund shares do not have cumulative
voting rights, which means that the holders of a majority of the shares voting
for the election of Trustees can elect all the Trustees. A Trustee may be
removed upon a majority vote of the shareholders qualified to vote in the
election. Shareholders holding 10% of the Trust's outstanding voting shares may
call a meeting of shareholders for the purpose of voting upon the question of
removal of any Trustee or for any other purpose. The 1940 Act requires the Trust
to assist shareholders in calling such a meeting.
 
   
Pursuant to the Trust's Declaration of Trust, the Trust may issue an unlimited
number of shares of the Fund, including an unlimited number of Class A, Class B,
Class C and Advisor Class shares of the Fund. Each share of the Fund has no par
value, represents an equal proportionate interest in the Fund with other Fund
shares and is entitled to such dividends and other distributions out of the
income earned and gain realized on the assets belonging to the Fund as may be
declared at the discretion of the Board of Trustees. Each Class A, Class B,
Class C and Advisor Class share of the Fund is equal in earnings, assets and
voting privileges to each other share of the Fund, except that each class of
shares of the Fund has exclusive voting rights with respect to its distribution
plan, and each class bears the expenses, if any, related to the distribution of
its shares. Fund shares, when issued, are fully paid and nonassessable.

                                  PERFORMANCE
 
- --------------------------------------------------------------------------------
 
FUND PERFORMANCE INFORMATION. The Fund, from time to time, may include
information on its investment results and/or comparisons of its investment
results to various unmanaged indices or results of other mutual funds or groups
of mutual funds in advertisements, sales literature or reports furnished to
present or prospective shareholders.
 
In such materials, the Fund may quote its average annual total return
("Standardized Return"). Standardized Return is calculated separately for each
class of shares of the Fund. Standardized Return shows percentage rates
reflecting the average annual change in the value of an assumed investment in
the Fund at the end of a one-year period and at the end of five- and ten-year
periods, reduced by the maximum applicable sales charge imposed on sales of Fund
shares. If a one-, five- and/or ten-year period has not yet elapsed, data will
be provided as of the end of a shorter period corresponding to the life of the
Fund. Standardized Return assumes the reinvestment of all dividends and other
distributions.
 
In addition, in order to more completely represent the Fund's performance or
more accurately compare the performance to other measures of investment return,
the Fund also may include other total return performance data ("Non-Standardized
Return") in advertisements, sales literature and shareholder reports.
Non-Standardized Return reflects percentage rates of return encompassing all
elements of return (i.e., income and capital appreciation or depreciation) and
assumes reinvestment of all dividends and other distributions. Non-Standardized
Return may be quoted for the same or different periods as those for which
Standardized Return is quoted; it may consist of an aggregate or average annual
percentage rate of return, actual year-by-year rates or any combination thereof.
Non-Standardized Return may or may not take sales charges into account;
performance data calculated without taking the effect of sales charges into
account will be higher than data including the effect of such charges.
 
The Fund's performance data will reflect past performance and will not
necessarily be indicative of future results. The Fund's investment results will
vary from time to time depending upon market conditions and the composition of
the Underlying Theme Funds' portfolios. These factors and possible differences
in calculation methods should be considered when comparing the Fund's investment
results with those published for other investment companies, other investment
vehicles and unmanaged indices. The Fund's results also should be considered
relative to the risks associated with its investment objective and policies. See
"Investment Results" in the Statement of Additional Information.
 
   
UNDERLYING THEME FUND PERFORMANCE. The Fund has a limited history and therefore
no performance record. Thus, the performance shown below is not the performance
of the Fund, but instead reflects the performance of the Underlying Theme Funds.
The following table shows the average annual total returns of Class A and Class
B shares of each Underlying Theme Fund for the most recent one- and five-year
periods (as applicable) and for the life of the Underlying Theme Funds. The
performance information reflects the maximum applicable sales charges and
distribution and service fees. Returns would be higher if these charges and fees
were not reflected. The Fund invests in the Advisor Class shares of the
Underlying Theme Funds, which are not subject to these sales charges and
distribution and service fees. However, Class A and Class B shares of the Fund
are subject to their own sales charges and distribution and service fees.

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.

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
                               recently organized entity, the Fund has a limited operating
                               history.

                                                                                            -------
</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 their fiscal years ended October 31, 1997.

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

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 November

forth in the preceding table) the expense ratios of the Underlying Theme Funds
are for their fiscal years ended October 31, 1997.

                            INVESTMENT OBJECTIVE AND
                                    POLICIES
 
- --------------------------------------------------------------------------------
 
   
The Fund seeks long-term growth of capital. Unlike a typical mutual fund, which
invests directly in securities, the Fund invests 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 Manager exercises no discretion in investing the Fund's assets. Rather, the
Manager periodically determines the allocation of the Fund's assets to the
Underlying Theme Funds according to the industry weightings of the companies
composing the Morgan Stanley Capital International All Country (AC) World Index
("MSCI"). (The MSCI is a broad unmanaged index of global stock prices, currently
comprising approximately 2,500 different issuers, located in 47 countries
including 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 its primary focus, in each of
these industries. For example, industries in the MSCI in which the Financial
Services Fund invests include the Banking, Financial Services, Insurance and
Real Estate industries. The percentage that those industries compose in the MSCI
is the initial weighting assigned to the Financial Services Fund. Where two or
more Underlying Theme Funds can invest in an industry, the weighting of that
industry in the MSCI is split equally among each qualifying Underlying Theme
Fund. See the Appendix for the allocation of the 38 industries to the Underlying
Theme Funds. Of course, the Underlying Theme Funds do not invest necessarily in
the same industries or the same companies that compose the MSCI. Because the
percentage weight assigned to each industry in the MSCI changes over time and
because the percentage of the Fund's assets invested in each Underlying Theme
Fund will change over time, the Manager will rebalance the Fund's assets among
the Underlying Theme Funds at least semi-annually. In addition, the Manager will
invest incoming money in, and satisfy redemption requests by redeeming shares
of, each Underlying Theme Fund according to the MSCI weighting as of the last
business day of the preceding month. As of November 30, 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......          %
Financial Services Fund..................          %
Health Care Fund.........................          %
Infrastructure Fund......................          %
Natural Resources Fund...................          %
Telecommunications Fund..................          %
</TABLE>
    
 
   
These percentages do not necessarily reflect the actual weighting of the Fund's
assets among the underlying Theme Funds because of changes in market valuations.
    
 
   
The Fund is a more diversified investment than any single Underlying Theme Fund.
However, because the Underlying Theme Funds are actively managed without any
attempt to reflect the country, industry or company weightings of the MSCI, the
Underlying Theme Funds will perform differently than the corresponding industry
components of the MSCI, and the Underlying Theme Funds will perform differently
than the overall MSCI. While the Fund does not therefore represent the
performance of the MSCI, it does represent a globally diversified portfolio,
with allocations among developed and emerging countries, industries and
companies intended to achieve long-term growth of capital.
    
 
   
The Fund is designed to meet the needs of investors who seek professional money
management services and who appreciate the advantages of diversification. The
Fund by itself should not be considered a complete investment program. As a
recently organized entity, the Fund has a limited operating history.
    
 
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.
In addition, the industries in which the Underlying Theme Funds invest may be
subject to political, environmental or other governmental regulation. Changes in
these factors may have a material effect on the products and services offered by
companies in these industries.
    
 
UNDERLYING THEME FUNDS' INVESTMENT ALLOCATION. The Manager allocates each
Underlying Theme Fund's (or its corresponding Portfolio's) assets among
securities of countries and in currency denominations where opportunities for
meeting each Underlying Theme Fund's investment objective are expected to be the
most attractive. Each Underlying Theme Fund may invest substantially in
securities denominated in foreign currencies. Under normal conditions, each
Underlying Theme Fund invests in the securities of issuers located in at least
three countries, including the United States; investments in securities of
issuers in any one country, other than the United States, will represent no more
than 40% of the Financial Services Portfolio's and the Telecommunication Fund's
total assets, and no more than 50% of the Infrastructure Portfolio's, the
Natural Resources Portfolio's, the Health Care Fund's and the Consumer Products
and Services Portfolio's total assets.
 
In analyzing specific companies for possible investment the Manager, on behalf
of the Underlying Theme Funds, ordinarily looks for several of the following
characteristics: above-average per share earnings growth; high return on
invested capital; a healthy balance sheet; sound financial and accounting
policies and overall financial strength; strong competitive advantages;
effective research and product development and marketing; development of new
technologies; efficient service; pricing flexibility; strong management; and
general operating characteristics that will enable the companies to compete
successfully in their respective markets. In assessing companies for the Natural
Resources Portfolio, the Manager will also evaluate, among other factors, their
capabilities for expanded exploration and production, superior exploration
programs and production techniques and facilities, current inventories, expected
production and demand levels and the potential to accumulate new resources.
 
FOREIGN INVESTMENTS. The Underlying Theme Funds' investments in foreign
securities may involve risks in addition to those of U.S. investments, including
increased political and economic risk, as well as exposure to currency
fluctuations. By investing in foreign securities, the Underlying Theme Funds
also have increased economic and political risks as they are exposed to events
and factors in the various world markets. This is especially true of an
Underlying Theme Fund that invests in emerging markets. Many investments in
emerging markets are considered speculative and therefore may offer greater
return potential, but have significantly greater risk. Also, to the extent that
an Underlying Theme Fund's investments are denominated in foreign currencies,
changes in the value of foreign currencies can significantly affect the fund's
share price.
 
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
 
                               Prospectus Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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; and (6) the
possible inability of an Underlying Theme Fund to purchase or sell a portfolio
security at a time when it would otherwise be favorable for it to do so, or the
possible need for an Underlying Theme Fund to sell a security at a
disadvantageous time, due to the need for the Underlying Theme Fund to maintain
"cover" or to set aside securities in connection with hedging transactions.
    
 
INVESTING IN SMALLER COMPANIES. Each Underlying Theme Fund may invest in smaller
companies that may present greater opportunities for capital appreciation, but
may also involve greater risks than large, established issuers. Such smaller
companies may have limited resources, and their securities may trade less
frequently and in more limited volume than the securities of larger, more
established companies. As a result, the prices of the securities of such smaller
companies may fluctuate to a greater degree than the prices of the securities of
other issuers.
 
PURCHASES AND REDEMPTIONS. From time to time, the Underlying Theme Funds may
experience relatively large purchases or redemptions due to rebalancing of the
Fund by the Manager. This may have a material effect on the Underlying Theme
Funds, because Underlying Theme Funds that experience redemptions as a result of
the rebalancing may have to sell portfolio securities and because Underlying
Theme Funds that receive additional cash will have to invest it. While it is
impossible to predict the overall impact of these transactions over time, there
could be adverse effects on portfolio management to the extent that Underlying
Theme Funds may be required to sell securities at times when they would not
otherwise do so, or receive cash that cannot be invested in an expeditious
manner. There may be tax consequences associated with purchases and sales of
securities, and such sales also may increase transaction costs.
 
                               Prospectus Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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.

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

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.

                         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 continue to qualify for treatment as a regulated
investment company under the Internal Revenue Code of 1986, as amended (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 Fund provides federal tax information to its shareholders annually,
including information about dividends and capital gain distributions paid during
the preceding year.
    
 
   
The information regarding capital gain distributions designates the portions of
those distributions that are subject to (1) the 20% maximum rate of tax (10% for
investors in the 15% marginal tax bracket) enacted by the Taxpayer Relief Act of
1997 ("Tax Act"), which applies to gain on securities held for more than 18
months, and (2) the 28% maximum tax rate, applicable to gain on securities held
for more than 12 and up to 18 months (which, prior to enactment of the Tax Act,
applied to all capital gain on securities held for more than one 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, Class B and Class C 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 Fund's assets
among the Underlying Theme Funds according to the MSCI weighting as of the last
business day of the preceding month.
    
 
DISTRIBUTION OF FUND SHARES. GT Global is the distributor of the Fund's 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, at its own expense, may provide promotional incentives to
broker/dealers that sell shares

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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
expected that shareholders would suffer any adverse financial consequences as a
result of any of these occurrences.

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, Class B and Class C
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 requested 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, Class B and Class C 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 the Underlying Theme Funds' shareholder servicing costs due to the
elimination of separate shareholder accounts that either currently are or have
potential to be invested in the Underlying Theme Funds. The estimated savings
produced by the operation of the Fund may offset most, if not all, the expenses
incurred by the Fund other than service and distribution fees. To the extent
that the Fund's expenses exceed the aggregate financial benefits to the
Underlying Theme Funds, the Manager will pay that excess.
    
 
CONFIRMATIONS AND REPORTS TO SHAREHOLDERS. Each time a transaction is made that
affects a shareholder's account in the Fund, the shareholder will receive from
the Transfer Agent a confirmation statement reflecting the transaction.
Confirmations for transactions effected pursuant to the Fund's Automatic
Investment Plan, Systematic Withdrawal Plan and automatic dividend reinvestment

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
program may be provided quarterly. Shortly after the end of the Fund's fiscal
year on December 31 and fiscal half-year on June 30 of each year, shareholders
receive an annual and semiannual report, respectively. In addition, the federal
income status of distributions made by the Fund to shareholders is reported
after the end of each calendar year on Form 1099-DIV. Under certain
circumstances, duplicate mailings of the foregoing reports to the same household
may be consolidated.
 
   
ORGANIZATION OF THE TRUST. The Trust was organized as a Massachusetts business
trust on August 26, 1996. The Trust currently consists of one series. From time
to time, the Trust may establish other series, each holding a distinct
investment portfolio and issuing a distinct series of the Trust's shares. Shares
of each series are entitled to one vote per share (with proportional voting for
fractional shares) and are transferable. Shareholders have no preemptive or
conversion rights.
    
 
   
If any additional series of the Trust are established, on any matter submitted
to a vote of shareholders, shares of each series will be voted by its
shareholders individually when the matter affects the specific interest of that
series only, such as approval of its investment management arrangements. The
shares of the Trust's series would be voted in the aggregate on other matters,
such as the election of Trustees and ratification of the selection by the Board
of Trustees of the Trust's independent accountants.
    
 
Normally there will be no annual meeting of shareholders in any year, except as
required under the 1940 Act. The Fund would be required to hold a shareholders'
meeting if at any time less than a majority of the Trustees holding office had
been elected by shareholders. Trustees continue to hold office until their
successors are elected and have qualified. Fund shares do not have cumulative
voting rights, which means that the holders of a majority of the shares voting
for the election of Trustees can elect all the Trustees. A Trustee may be
removed upon a majority vote of the shareholders qualified to vote in the
election. Shareholders holding 10% of the Trust's outstanding voting shares may
call a meeting of shareholders for the purpose of voting upon the question of
removal of any Trustee or for any other purpose. The 1940 Act requires the Trust
to assist shareholders in calling such a meeting.
 
   
The Fund offers Advisor Class shares through this Prospectus to certain
investors. The Fund also offers Class A, Class B and Class C 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,
Class B and Class C shares of the Fund because of the higher expenses borne by
the Class A, Class B and Class C 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, Class B or
Class C 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,
Class C and Advisor Class shares of the Fund. Each share of the Fund has no par
value, represents an equal proportionate interest in the Fund with other Fund
shares and is entitled to such dividends and other distributions out of the
income earned and gain realized on the assets belonging to the Fund as may be
declared at the discretion of the Board of Trustees. Each Class A, Class B,
Class C and Advisor Class share of the Fund is equal in earnings, assets and
voting privileges to each other share in the Fund, except that each class of
shares of the Fund has exclusive voting rights with respect to its distribution
plan, and each class bears the expenses, if any, related to the distribution of
its shares. Fund shares, when issued, are fully paid and nonassessable.

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

                                    POLICIES

INVESTMENT POLICIES OF THE FUND
The following supplements the information contained in the Prospectus concerning
the investment policies of the Fund.
 
U.S. GOVERNMENT SECURITIES. The Fund may invest in various direct obligations of
the U.S. Treasury and obligations issued or guaranteed by the U.S. government or
one  of  its  agencies  or  instrumentalities  (collectively,  "U.S.  government
securities"). Among the U.S. government securities that may be held by the  Fund
are  securities that are  supported by the  full faith and  credit of the United
States; securities that are supported by the right of the issuer to borrow  from
the U.S. Treasury; and securities that are supported solely by the credit of the
instrumentality.
 
REPURCHASE   AGREEMENTS.  The  Fund  may  invest  in  repurchase  agreements.  A
repurchase agreement is  a transaction  in which the  Fund purchases  securities
from a bank or recognized securities dealer and simultaneously commits to resell
the  securities to the bank or dealer on  an agreed-upon date or upon demand and
at a price reflecting a market rate of interest unrelated to the coupon rate  or
maturity  of  the  purchased  securities.  The  Fund  maintains  custody  of the
underlying securities prior  to their  repurchase; thus, the  obligation of  the
bank  or dealer to pay the repurchase price on the date agreed to is, in effect,
secured by such securities. If  the value of these  securities is less than  the
repurchase price, plus any agreed-upon additional amount, the other party to the
agreement must provide additional collateral so that at all times the collateral
is  at  least equal  to the  repurchase price,  plus any  agreed-upon additional
amount. The difference between the total  amount to be received upon  repurchase
of  the securities and the  price that was paid by  the Fund upon acquisition is
accrued as  interest  and included  in  its net  investment  income.  Repurchase
agreements  carry  certain  risks  not  associated  with  direct  investments in
securities, including possible declines  in the market  value of the  underlying
securities  and delays and costs to the Fund  if the other party to a repurchase
agreement becomes insolvent.
 
INVESTMENT POLICIES OF THE UNDERLYING THEME FUNDS
The following supplements the information contained in the Prospectus concerning
the investment  policies and  limitations of  the Underlying  Theme Funds.  More
information  about the investment  policies and restrictions  and the investment
limitations of each Underlying Theme Fund  is set forth in the Underlying  Theme
Funds' prospectus and statement of additional information.
 
The Underlying Theme Funds are diversified series of G.T. Investment Funds, Inc.
(the  "Company"), a  registered open-end  management investment  company. The GT
Global Consumer  Products and  Services Fund  ("Consumer Products  and  Services
Fund"), GT Global Financial Services Fund ("Financial Services Fund"), GT Global
Infrastructure  Fund ("Infrastructure  Fund"), and  GT Global  Natural Resources
Fund ("Natural Resources Fund") (each,  a "Feeder Fund," and, collectively,  the
"Feeder  Funds") invest  all of their  investable assets in  the Global Consumer
Products and  Services Portfolio,  Global Financial  Services Portfolio,  Global
Infrastructure  Portfolio,  and  Global  Natural  Resources  Portfolio  (each, a
"Portfolio," and, collectively, the "Portfolios"), respectively.
 
Each Portfolio is  a subtrust (a  "series") of Global  Investment Portfolio  (an
open-end  management investment  company) with  an investment  objective that is
identical to  that of  its  corresponding Underlying  Theme Fund.  Whenever  the
phrase "all of the Underlying Theme Fund's investable assets" is used herein, it
means  that the  only investment securities  held by  a Feeder Fund  will be its
interest in  its  corresponding  Portfolio.  A  Feeder  Fund  may  withdraw  its
investment in its corresponding Portfolio at any time, if the Company's Board of
Directors determines that it is in the best interests of the Feeder Fund and its
shareholders to do so. Upon any such withdrawal, a Feeder Fund's assets would be
invested  in  accordance  with  the  investment  policies  of  its corresponding
Portfolio described below and in the Underlying Theme Funds' prospectus.
 
The investment objective of  each Feeder Fund is  long-term capital growth.  The
investment objectives of the GT Global Health Care Fund ("Health Care Fund") and
the  GT Global Telecommunications Fund ("Telecommunications Fund") are long-term
capital appreciation and long-term capital growth, respectively. The  Portfolios
and the Health Care Fund and the Telecommunications Fund, together, are referred
to herein as the "Underlying Theme Portfolios."
 
                   Statement of Additional Information Page 2
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
SELECTION  OF EQUITY INVESTMENTS.  With respect to  the Global Natural Resources
Portfolio, the Manager  has identified four  areas that it  expects will  create
investment  opportunities: (i)  improving supply/demand  fundamentals, which may
result in higher  commodity prices;  (ii) privatization  of state-owned  natural
resource  businesses; (iii) management which can improve production efficiencies
without correspondingly increasing commodity prices; and (iv) service  companies
with  emerging technologies that  can enhance productivity  or reduce production
costs. Of course,  there is  no certainty that  these factors  will produce  the
anticipated results.
 
With  respect to  the Telecommunications Fund,  the Manager  has identified four
areas that it expects will create investment opportunities: (i) deregulation  of
companies  in  the industry,  which will  allow  competition to  promote greater
efficiencies; (ii) privatization  of state-owned telecommunications  businesses;
(iii) development of infrastructure in underdeveloped countries and upgrading of
services  in other countries;  and (iv) emerging  technologies that will enhance
productivity and reduce  costs in  the telecommunications  industry. Of  course,
there is no certainty that these factors will produce the anticipated results.
 
There  may be  times when,  in the  opinion of  the Manager,  prevailing market,
economic  or  political  conditions  warrant  reducing  the  proportion  of  the
Underlying Theme Portfolios' assets invested in equity securities and increasing
the  proportion held in cash (U.S.  dollars, foreign currencies or multinational
currency units) or  invested in  debt securities  or high  quality money  market
instruments  issued  by  corporations,  or  the  United  States,  or  a  foreign
government. A portion of each Underlying Theme Portfolio's assets normally  will
be  held in  cash (U.S.  dollars, foreign  currencies or  multinational currency
units) or invested in foreign or domestic high quality money market  instruments
pending investment of proceeds from new sales of Underlying Theme Fund shares to
provide for ongoing expenses and to satisfy redemptions.
 
For  each  Underlying  Theme  Portfolio's  investment  purposes,  an  issuer  is
typically considered as located in a  particular country if it (a) is  organized
under  the laws of or  has its principal office in  a particular country, or (b)
normally derives  50%  or more  of  its total  revenues  from business  in  that
country,  provided  that, in  the  Manager's view,  the  value of  such issuer's
securities will tend to reflect such  country's development to a greater  extent
than  developments elsewhere. However, these  are not absolute requirements, and
certain companies incorporated  in a  particular country and  considered by  the
Manager to be located in that country may have substantial foreign operations or
subsidiaries  and/or export sales exceeding in size  the assets or sales in that
country.
 
In  certain  countries,  governmental  restrictions  and  other  limitations  on
investment  may affect a Underlying Theme  Portfolio's ability to invest in such
countries. In addition, in some instances only special classes of securities may
be purchased by  foreigners and  the market  prices, liquidity  and rights  with
respect to those securities may vary from shares owned by nationals. The Manager
is not aware at this time of the existence of any investment or exchange control
regulations  which might substantially  impair the operations  of the Underlying
Theme Portfolios  as described  in the  Underlying Theme  Funds' prospectus  and
statement  of additional information.  Restrictions may in  the future, however,
make it undesirable to invest in certain countries. None of the Underlying Theme
Portfolios has a present intention of  making any significant investment in  any
country or stock market in which the Manager considers the political or economic
situation  to threaten  a Underlying Theme  Portfolio with  substantial or total
loss of its investment in such country or market.
 
INVESTMENTS IN OTHER INVESTMENT COMPANIES.  Each Underlying Theme Portfolio  may
invest  in the securities of investment  companies within the limitations of the
Investment Company Act of 1940, as  amended (the "1940 Act"). These  limitations
currently  provide that, in general, an  Underlying Theme Portfolio may purchase
shares of  an investment  company unless  (a)  such a  purchase would  cause  an
Underlying  Theme Portfolio to  own in the  aggregate more than  3% of the total
outstanding voting stock of the investment company or (b) such a purchase  would
cause the Underlying Theme Portfolio to have more than 5% of its assets invested
in  the  investment  company or  more  than 10%  of  its assets  invested  in an
aggregate of all such  investment companies. The  foregoing restrictions do  not
apply  to the investment of the  Feeder Funds in their corresponding Portfolios.
Investment in  closed-end  investment  companies  may  involve  the  payment  of
substantial  premiums above the  value of such  companies' portfolio securities.
Each Underlying Theme  Portfolio does not  intend to invest  in such  investment
companies unless, in the judgment of the Manager, the potential benefits of such
investments  justify the payment of any  applicable premiums. The return on such
securities will be reduced  by operating expenses  of such companies,  including
payments to the investment managers of those investment companies.
 
DEPOSITORY  RECEIPTS.  An  Underlying  Theme Portfolio  may  hold  securities of
foreign issuers in the form  of American Depository Receipts ("ADRs"),  American
Depository  Shares ("ADSs") and  European Depository Receipts  ("EDRs") or other
securities convertible  into  securities  of  eligible  foreign  issuers.  These
securities  may  not necessarily  be  denominated in  the  same currency  as the
securities for which they may be  exchanged. ADRs and ADSs are typically  issued
by  an  American bank  or  trust company  and  evidence ownership  of underlying
securities issued by a foreign corporation. EDRs,
 
                   Statement of Additional Information Page 3
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
which are sometimes referred to as Continental Depository Receipts ("CDRs"), are
issued in Europe  typically by foreign  banks and trust  companies and  evidence
ownership  of either foreign or domestic securities. Generally, ADRs and ADSs in
registered form are  designed for  use in U.S.  securities markets  and EDRs  in
bearer form are designed for use in European securities markets. For purposes of
each  Underlying  Theme  Portfolio's investment  policies,  an  Underlying Theme
Portfolio's investments in ADRs, ADSs and EDRs will be deemed to be  investments
in  the equity securities representing securities  of foreign issuers into which
they may be converted.
 
ADR facilities may be established as either "unsponsored" or "sponsored."  While
ADRs  issued under these two  types of facilities are  in some respects similar,
there are distinctions between  them relating to the  rights and obligations  of
ADR holders and the practices of market participants. A depository may establish
an  unsponsored  facility  without  participation by  (or  even  necessarily the
acquiescence of) the issuer of the deposited securities, although typically  the
depository  requests a  letter of  non-objection from  such issuer  prior to the
establishment of the facility.  Holders of unsponsored  ADRs generally bear  all
the  costs  of such  facilities. The  depository usually  charges fees  upon the
deposit and withdrawal of the deposited securities, the conversion of  dividends
into   U.S.  dollars,  the  disposition   of  non-cash  distributions,  and  the
performance of  other  services.  The  depository  of  an  unsponsored  facility
frequently  is  under  no obligation  to  distribute  shareholder communications
received from the issuer of the  deposited securities or to pass-through  voting
rights  to ADR  holders in  respect of  the deposited  securities. Sponsored ADR
facilities are created in generally  the same manner as unsponsored  facilities,
except  that  the  issuer of  the  deposited  securities enters  into  a deposit
agreement with the  depository. The deposit  agreement sets out  the rights  and
responsibilities  of  the  issuer,  the depository  and  the  ADR  holders. With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository), although ADR holders continue to bear certain other costs (such  as
deposit  and withdrawal fees).  Under the terms  of most sponsored arrangements,
depositories agree  to distribute  notices of  shareholder meetings  and  voting
instructions, and to provide shareholder communications and other information to
the  ADR holders at the  request of the issuer  of the deposited securities. The
Underlying Theme Portfolios may invest in both sponsored and unsponsored ADRs.
 
WARRANTS OR RIGHTS. Warrants  or rights may be  acquired by an Underlying  Theme
Portfolio  in connection  with other  securities or  separately and  provide the
Underlying Theme Portfolio  with the  right to purchase  at a  later date  other
securities of the issuer.
 
   
LENDING  OF UNDERLYING THEME PORTFOLIO SECURITIES.  For the purpose of realizing
additional income, each Underlying Theme Portfolio may make secured loans of its
securities holdings  amounting  to  not  more than  30%  of  its  total  assets.
Securities  loans are made to broker/dealers or institutional investors pursuant
to agreements requiring that the loans be continuously secured by collateral  at
least  equal at all times  to the value of the  securities lent plus any accrued
interest, "marked to market" on a  daily basis. The Underlying Theme  Portfolios
may pay reasonable administrative and custodial fees in connection with the loan
of  their securities.  While the securities  loan is  outstanding, an Underlying
Theme Portfolio  will continue  to receive  the equivalent  of the  interest  or
dividends  paid by  the issuer  on the  securities, as  well as  interest on the
investment of the  collateral or a  fee from the  borrower. An Underlying  Theme
Portfolio  will have a right to call  each loan and obtain the securities within
the stated settlement period.  An Underlying Theme Portfolio  will not have  the
right  to vote equity securities while they are being lent, but it may call in a
loan in anticipation of  any important vote.  Loans will only  be made to  firms
deemed by the Manager to be of good standing and will not be made unless, in the
judgment  of the Manager, the  consideration to be earned  from such loans would
justify the risk. The risks in lending Underlying Theme Portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional collateral or  in recovery  of the  securities and  possible loss  of
rights in the collateral should the borrower fail financially.
    
 
COMMERCIAL   BANK  OBLIGATIONS.  For  the  purposes  of  each  Underlying  Theme
Portfolio's investment policies with respect to bank obligations, obligations of
foreign branches  of U.S.  banks and  of foreign  banks are  obligations of  the
issuing bank and may be general obligations of the parent bank. Such obligations
may, however, be limited by the terms of a specific obligation and by government
regulation.  As with investments in  non-U.S. securities in general, investments
in the obligations of foreign  branches of U.S. banks  and of foreign banks  may
subject  each Underlying Theme Portfolio to  investment risks that are different
in some  respects from  those of  investments in  obligations of  U.S.  issuers.
Although  each  Underlying Theme  Portfolio  will typically  acquire obligations
issued and supported by the credit of U.S. or foreign banks having total  assets
at  the time of purchase of $1 billion or more, this $1 billion figure is not an
investment policy or  restriction of  each Underlying Theme  Portfolio. For  the
purposes  of calculation with respect to the  $1 billion figure, the assets of a
bank will be deemed to include the assets of its U.S. and non-U.S. branches.
 
                   Statement of Additional Information Page 4
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
REPURCHASE AGREEMENTS.  A repurchase  agreement  is a  transaction in  which  an
Underlying  Theme  Portfolio  purchases a  security  from a  bank  or recognized
securities dealer and simultaneously commits to resell that security to the bank
or dealer on  an agreed-upon date  or upon demand  and at a  price reflecting  a
market  rate  of  interest unrelated  to  the  coupon rate  or  maturity  of the
purchased security.  Although  repurchase  agreements carry  certain  risks  not
associated  with direct investments in securities, including possible decline in
the market  value of  the underlying  securities  and delays  and costs  to  the
Underlying  Theme  Portfolio  if the  other  party to  the  repurchase agreement
becomes  bankrupt,  the  Underlying  Theme  Portfolios  intend  to  enter   into
repurchase  agreements only  with banks and  dealers believed by  the Manager to
present minimal credit risks  in accordance with  guidelines established by  the
Company's  Board of Directors or Global Investment Portfolio's Board of Trustees
(each a "Board"  and, collectively,  the "Boards"), as  applicable. The  Manager
will  review and  monitor the  creditworthiness of  such institutions  under the
applicable Board's general supervision.
 
Each Underlying  Theme  Portfolio  will invest  only  in  repurchase  agreements
collateralized  at all times in an amount at least equal to the repurchase price
plus accrued interest. To  the extent that  the proceeds from  any sale of  such
collateral  upon a default  in the obligation  to repurchase were  less than the
repurchase price, an  Underlying Theme  Portfolio would  suffer a  loss. If  the
financial  institution that is  party to the  repurchase agreement petitions for
bankruptcy or  otherwise  becomes subject  to  bankruptcy or  other  liquidation
proceedings,  there  may  be  restrictions on  an  Underlying  Theme Portfolio's
ability to sell the collateral and it could suffer a loss. However, with respect
to financial  institutions  whose  bankruptcy  or  liquidation  proceedings  are
subject  to the U.S. Bankruptcy Code, each Underlying Theme Portfolio intends to
comply with provisions under such code that would allow the immediate resale  of
such  collateral.  Each  Underlying  Theme  Portfolio  will  not  enter  into  a
repurchase agreement with a maturity  of more than seven  days if, as a  result,
more  than 15% of the value of its  net assets (except for the Health Care Fund,
more than  10% of  the value  of its  total assets)  would be  invested in  such
repurchase agreements and other illiquid investments.
 
BORROWING,   REVERSE  REPURCHASE   AGREEMENTS  AND   "ROLL"  TRANSACTIONS.  Each
Underlying Theme Portfolio's  borrowings will not  exceed 33 1/3%  of its  total
assets,  I.E., the Underlying  Theme Portfolio's total assets  at all times will
equal at  least  300%  of  the  amount  of  outstanding  borrowings.  If  market
fluctuations in the value of an Underlying Theme Portfolio's securities holdings
or  other factors cause the ratio of  its total assets to outstanding borrowings
to fall below 300%, within three  days (excluding Sundays and holidays) of  such
event  that  Underlying  Theme  Portfolio  may  be  required  to  sell portfolio
securities to restore the  300% asset coverage, even  though from an  investment
standpoint  such sales might be disadvantageous. Each Underlying Theme Portfolio
may also borrow up to 5% of its total assets for temporary or emergency purposes
other than to meet redemptions. Any  borrowing by an Underlying Theme  Portfolio
may  cause greater fluctuation in the value of its shares than would be the case
if it did not borrow.
 
Each Underlying Theme Portfolio's  fundamental investment limitations permit  it
to  borrow  money  for  leveraging  purposes.  However,  each  Underlying  Theme
Portfolio (except the Health Care Fund)  is currently prohibited, pursuant to  a
non-fundamental  investment policy,  from borrowing  money in  order to purchase
securities. Nevertheless,  this policy  may  be changed  in  the future  by  the
applicable  Board.  In  the event  that  an Underlying  Theme  Portfolio employs
leverage in the future, it would be subject to certain additional risks. Use  of
leverage  creates  an  opportunity  for  greater  growth  of  capital  but would
exaggerate any increases or decreases in the  net asset value of a Feeder  Fund,
or  an  Underlying Theme  Portfolio.  When the  income  and gains  on securities
purchased with the proceeds of borrowings  exceed the costs of such  borrowings,
an Underlying Theme Portfolio's earnings or a Feeder Fund's net asset value will
increase faster than otherwise would be the case; conversely, if such income and
gains  fail to exceed such costs, an  Underlying Theme Portfolio's earnings or a
Feeder Fund's net asset value would  decline faster than would otherwise be  the
case.
 
Each  Underlying Theme Portfolio may enter into reverse repurchase agreements. A
reverse repurchase agreement is a borrowing transaction in which the  Underlying
Theme  Portfolio transfers possession of a security  to another party, such as a
bank or broker/dealer, in return for cash, and agrees to repurchase the security
in the future  at an agreed  upon price, which  includes an interest  component.
Each   Underlying  Theme   Portfolio  may   also  engage   in  "roll"  borrowing
transactions, which involve the sale of Government National Mortgage Association
certificates or  other securities  together  with a  commitment (for  which  the
Underlying  Theme  Portfolio may  receive a  fee) to  purchase similar,  but not
identical, securities at  a future  date. Each Underlying  Theme Portfolio  will
maintain, in a segregated account with a custodian, cash or liquid securities in
an  amount sufficient  to cover  its obligations  under "roll"  transactions and
reverse repurchase agreements  with broker/dealers. No  segregation is  required
for reverse repurchase agreements with banks.
 
SHORT  SALES. Each Underlying  Theme Portfolio (except the  Health Care Fund) is
authorized to make short sales of securities.  A short sale is a transaction  in
which  an Underlying Theme  Portfolio sells a security  in anticipation that the
market price of that  security will decline. An  Underlying Theme Portfolio  may
make short sales (i) as a form of hedging to
 
                   Statement of Additional Information Page 5
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
offset   potential  declines  in  long  positions  in  securities  it  owns,  or
anticipates acquiring, or in similar securities,  and (ii) in order to  maintain
flexibility in its securities holdings.
 
When  an Underlying Theme Portfolio makes a short sale of a security it does not
own, it must borrow the security sold short and deliver it to the  broker/dealer
or other intermediary through which it made the short sale. The Underlying Theme
Portfolio  may have to pay a fee  to borrow particular securities and will often
be obligated to pay over any payments received on such borrowed securities.
 
An Underlying Theme Portfolio's obligation to replace the borrowed security when
the borrowing is called or expires will be secured by collateral deposited  with
the  intermediary.  The  Underlying Theme  Portfolio  will also  be  required to
deposit collateral with its custodian to  the extent, if any, necessary so  that
the  value of both collateral deposits in the aggregate is at all times equal to
at least 100% of the current market value of the security sold short.  Depending
on  arrangements made with the intermediary  from which it borrowed the security
regarding payment of any amounts received by it on such security, an  Underlying
Theme  Portfolio  may  not  receive any  payments  (including  interest)  on its
collateral deposited with such intermediary.
 
If the price of the security sold short increases between the time of the  short
sale  and the time an Underlying Theme Portfolio replaces the borrowed security,
it will incur a  loss; conversely, if the  price declines, the Underlying  Theme
Portfolio  will  realize  a gain.  Any  gain  will be  decreased,  and  any loss
increased, by the transaction costs associated with the transaction. Although an
Underlying Theme Portfolio's gain is limited by  the price at which it sold  the
security short, its potential loss theoretically is unlimited.
 
No  Underlying Theme Portfolio will make a short sale if, after giving effect to
the sale, the market value of the securities sold short exceeds 25% of the value
of its total assets or  its aggregate short sales of  the securities of any  one
issuer  exceed the lesser of 2% of its net assets or 2% of the securities of any
class of the issuer. Moreover, an Underlying Theme Portfolio may engage in short
sales only with respect to securities listed on a national securities  exchange.
An  Underlying Theme  Portfolio may make  short sales "against  the box" without
respect to such limitations. In this type of short sale, at the time of the sale
the Underlying Theme Portfolio owns  the security it has  sold short or has  the
immediate and unconditional right to acquire at no additional cost the identical
security.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use by  the Underlying Theme  Portfolios of options,  futures contracts and
forward currency contracts ("Forward Contracts") involves special considerations
and risks, as described  below. Risks pertaining  to particular instruments  are
described in the sections that follow.
 
        (1)  Successful  use  of  most of  these  instruments  depends  upon the
    Manager's ability  to  predict  movements  of  the  overall  securities  and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Manager is experienced in the
    use  of these  instruments, there  can be  no assurance  that any particular
    strategy adopted will succeed.
 
        (2) There  might  be  imperfect correlation,  or  even  no  correlation,
    between  price  movements  of  an  instrument  and  price  movements  of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge  increased by less  than the  decline in value  of the  hedged
    investment,  the  hedge  would  not  be fully  successful.  Such  a  lack of
    correlation might  occur  due to  factors  unrelated  to the  value  of  the
    investments  being hedged,  such as  speculative or  other pressures  on the
    markets in  which the  hedging instrument  is traded.  The effectiveness  of
    hedges  using hedging  instruments on indices  will depend on  the degree of
    correlation between price movements in the index and price movements in  the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or  partially offsetting the negative  effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by  offsetting the positive  effect of favorable  price
    movements  in the  hedged investments. For  example, if  an Underlying Theme
    Portfolio entered into a short hedge because the Manager projected a decline
    in the price of
 
                   Statement of Additional Information Page 6
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
    a security in the Underlying Theme  Portfolio's portfolio, and the price  of
    that security increased instead, the gain from that increase might be wholly
    or  partially offset by  a decline in  the price of  the hedging instrument.
    Moreover, if the price of the  hedging instrument declined by more than  the
    increase  in the price of the security, the Underlying Theme Portfolio could
    suffer a loss.  In either such  case, the Underlying  Theme Portfolio  would
    have been in a better position had it not hedged at all.
 
        (4)  As described below, an Underlying Theme Portfolio might be required
    to maintain assets as "cover,"  maintain segregated accounts or make  margin
    payments  when it  takes positions  in instruments  involving obligations to
    third parties  (I.E.,  instruments other  than  purchased options).  If  the
    Underlying  Theme Portfolio were  unable to close out  its positions in such
    instruments, it might  be required to  continue to maintain  such assets  or
    accounts  or make such  payments until the position  expired or matured. The
    requirements might impair the Underlying Theme Portfolio's ability to sell a
    portfolio security or make an investment  at a time when it would  otherwise
    be favorable to do so, or require that the Underlying Theme Portfolio sell a
    portfolio   security  at  a  disadvantageous   time.  The  Underlying  Theme
    Portfolio's ability  to close  out  a position  in  an instrument  prior  to
    expiration or maturity depends on the existence of a liquid secondary market
    or,  in the  absence of such  a market,  the ability and  willingness of the
    other party to the transaction ("contra party") to enter into a  transaction
    closing out the position. Therefore, there is no assurance that any position
    can  be closed out at  a time and price that  is favorable to the Underlying
    Theme Portfolio.
 
WRITING CALL OPTIONS
Each Underlying Theme  Portfolio may  write (sell) call  options on  securities,
indices and currencies. Call options generally will be written on securities and
currencies  that, in the  opinion of the  Manager, are not  expected to make any
major price moves in the near future but that, over the long term, are deemed to
be attractive investments for the Underlying Theme Portfolios.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
style) or on (European style) a certain  date (the expiration date). So long  as
the  obligation of  the writer  of a  call option  continues, he  or she  may be
assigned an exercise  notice, requiring  him or  her to  deliver the  underlying
security  or currency  against payment  of the  exercise price.  This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer  effects  a closing  purchase  transaction by  purchasing  an  option
identical to that previously sold.
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on the basis of investment considerations consistent with  each
Underlying  Theme Portfolio's investment objective.  When writing a call option,
an Underlying  Theme  Portfolio,  in  return  for  the  premium,  gives  up  the
opportunity  for  profit from  a price  increase in  the underlying  security or
currency above the exercise price, and retains the risk of loss should the price
of the  security  or  currency  decline.  Unlike  one  who  owns  securities  or
currencies  not  subject to  an  option, an  Underlying  Theme Portfolio  has no
control over  when it  may be  required  to sell  the underlying  securities  or
currencies,  since  most options  may  be exercised  at  any time  prior  to the
option's expiration. If  a call option  that an Underlying  Theme Portfolio  has
written  expires, it will realize a gain  in the amount of the premium; however,
such gain may  be offset  by a  decline in the  market value  of the  underlying
security  or currency during the option period. If the call option is exercised,
the Underlying Theme Portfolio will realize a gain or loss from the sale of  the
underlying  security  or currency,  which  will be  increased  or offset  by the
premium received. The Underlying Theme Portfolios do not consider a security  or
currency  covered by a call option to be "pledged" as that term is used in their
policies that limit the pledging or mortgaging of their assets.
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option will be exercised and an Underlying Theme Portfolio
will be obligated  to sell  the security  or currency  at less  than its  market
value.
 
The  premium  that an  Underlying Theme  Portfolio receives  for writing  a call
option is deemed to constitute  the market value of  an option. The premium  the
Underlying Theme Portfolio will receive from writing a call option will reflect,
among  other things, the current market  price of the underlying investment, the
relationship of the exercise  price to such market  price, the historical  price
volatility of the underlying investment, and the length of the option period. In
determining whether a particular call option should be written, the Manager will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing  transactions  will be  effected  in order  to  realize a  profit  on an
outstanding call  option, to  prevent an  underlying security  or currency  from
being  called or  to permit  the sale  of the  underlying security  or currency.
Furthermore, effecting a
 
                   Statement of Additional Information Page 7
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
closing transaction will permit an  Underlying Theme Portfolio to write  another
call  option  on the  underlying security  or currency  with either  a different
exercise price or expiration date, or both.
 
Each Underlying Theme Portfolio  will pay transaction  costs in connection  with
the  writing  of  options  and  in  entering  into  closing  purchase contracts.
Transaction costs relating to  options activity are  normally higher than  those
applicable to purchases and sales of portfolio securities.
 
The  exercise price of the  options may be below, equal  to or above the current
market values of the  underlying securities, indices or  currencies at the  time
the  options are written. From  time to time, an  Underlying Theme Portfolio may
purchase an underlying security or currency for delivery in accordance with  the
exercise of an option, rather than delivering such security or currency from its
portfolio. In such cases, additional costs will be incurred.
 
An  Underlying Theme  Portfolio will  realize a  profit or  loss from  a closing
purchase  transaction  if  the  cost  of  the  transaction  is  less  or   more,
respectively,  than  the  premium  received  from  writing  the  option. Because
increases in the market price of a call option generally will reflect  increases
in  the market price of the underlying  security or currency, any loss resulting
from the repurchase of a call option is likely to be offset in whole or in  part
by  appreciation of the  underlying security or currency  owned by an Underlying
Theme Portfolio.
 
WRITING PUT OPTIONS
Each Underlying Theme Portfolio may write put options on securities, indices and
currencies. A put option gives  the purchaser of the  option the right to  sell,
and  the  writer (seller)  the  obligation to  buy,  the underlying  security or
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style) the  expiration date.  The operation  of put  options in other
respects, including their related risks and rewards, is substantially  identical
to that of call options.
 
An Underlying Theme Portfolio generally would write put options in circumstances
where the Manager wishes to purchase the underlying security or currency for the
Underlying  Theme Portfolio's holdings at a  price lower than the current market
price of the security or currency. In such event, an Underlying Theme  Portfolio
would  write a  put option  at an  exercise price  that, reduced  by the premium
received on the option, reflects the lower price it is willing to pay. Since the
Underlying Theme Portfolio  would also  receive interest on  debt securities  or
currencies  maintained to cover the exercise price of the option, this technique
could be used to  enhance current return during  periods of market  uncertainty.
The  risk in such a transaction would be that the market price of the underlying
security or currency  would decline below  the exercise price  less the  premium
received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected  that the  put option  will  be exercised  and an  Underlying Theme
Portfolio will be obligated to purchase the security or currency at greater than
its market value.
 
PURCHASING PUT OPTIONS
Each Underlying Theme Portfolio may purchase put options on securities,  indices
and  currencies. As the  holder of a  put option, an  Underlying Theme Portfolio
would have the right to sell the underlying security or currency at the exercise
price at any time until (American  style) or on (European style) the  expiration
date.  An Underlying  Theme Portfolio may  enter into  closing sale transactions
with respect to  such options,  exercise such option  or permit  such option  to
expire.
 
Each  Underlying  Theme Portfolio  may purchase  a put  option on  an underlying
security or currency ("protective put") owned by the Underlying Theme  Portfolio
in  order to protect against an anticipated decline in the value of the security
or currency. Such hedge protection is provided  only during the life of the  put
option  when the Underlying Theme Portfolio, as the holder of the put option, is
able to  sell the  underlying security  or currency  at the  put exercise  price
regardless  of  any  decline  in  the  underlying  security's  market  price  or
currency's exchange value. For example, a  put option may be purchased in  order
to  protect unrealized appreciation  of a security or  currency when the Manager
deems it desirable to continue to hold  the security or currency because of  tax
considerations.  The premium paid  for the put option  and any transaction costs
would reduce any profit otherwise  available for distribution when the  security
or currency is eventually sold.
 
An  Underlying Theme Portfolio may  also purchase put options  at a time when it
does not own the underlying security or currency. By purchasing put options on a
security or currency it does not  own, that Underlying Theme Portfolio seeks  to
benefit  from  a decline  in  the market  price  of the  underlying  security or
currency. If the put option is not sold when it has remaining value, and if  the
market  price of the underlying security or currency remains equal to or greater
than the exercise price during the life of the put option, the Underlying  Theme
Portfolio  will lose its entire  investment in the put  option. In order for the
purchase of a put option  to be profitable, the  market price of the  underlying
security or currency
 
                   Statement of Additional Information Page 8
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
must  decline sufficiently  below the  exercise price  to cover  the premium and
transaction costs, unless the put option is sold in a closing sale transaction.
 
PURCHASING CALL OPTIONS
Each Underlying Theme Portfolio may purchase call options on securities, indices
and currencies. As the  holder of a call  option, an Underlying Theme  Portfolio
would  have the  right to  purchase the underlying  security or  currency at the
exercise price at  any time until  (American style) or  on (European style)  the
expiration  date.  An Underlying  Theme Portfolio  may  enter into  closing sale
transactions with respect to such options, exercise such options or permit  such
options to expire.
 
Call  options may be purchased by an  Underlying Theme Portfolio for the purpose
of acquiring the underlying security or currency for its portfolio. Utilized  in
this  fashion, the  purchase of  call options  would enable  an Underlying Theme
Portfolio to acquire the security or currency at the exercise price of the  call
option  plus the premium paid. At times,  the net cost of acquiring the security
or currency in this manner may be  less than the cost of acquiring the  security
or  currency directly. This technique may also  be useful to an Underlying Theme
Portfolio in purchasing a large block of securities that would be more difficult
to acquire by direct market purchases. So  long as it holds such a call  option,
rather  than the  underlying security or  currency itself,  the Underlying Theme
Portfolio is partially protected from any unexpected decline in the market price
of the underlying security or currency and, in such event, could allow the  call
option  to expire, incurring a  loss only to the extent  of the premium paid for
the option.
 
An Underlying  Theme Portfolio  may  also purchase  call options  on  underlying
securities  or currencies it owns  in order to protect  unrealized gains on call
options previously written  by it.  A call option  could be  purchased for  this
purpose  where  tax considerations  make it  inadvisable  to realize  such gains
through a closing purchase  transaction. Call options may  also be purchased  at
times  to  avoid  realizing losses  that  would  result in  a  reduction  of the
Underlying Theme Portfolio's  current return. For  example, where an  Underlying
Theme  Portfolio has written a call option on an underlying security or currency
having a  current  market value  below  the price  at  which it  purchased  such
security  or  currency, an  increase in  the  market price  could result  in the
exercise of the call  option written by the  Underlying Theme Portfolio and  the
realization  of a loss on the  underlying security or currency. Accordingly, the
Underlying Theme Portfolio could purchase a  call option on the same  underlying
security  or  currency,  which  could  be  exercised  to  fulfill  its  delivery
obligations under its  written call (if  it is exercised).  This strategy  could
allow  the Underlying Theme Portfolio to avoid selling the portfolio security or
currency at a time when it has an unrealized loss; however, the Underlying Theme
Portfolio would  have  to  pay  a  premium to  purchase  the  call  option  plus
transaction costs.
 
Aggregate  premiums paid  for put and  call options  will not exceed  5% of each
Underlying Theme Portfolio's total assets at the time of each purchase.
 
An Underlying Theme Portfolio  may attempt to  accomplish objectives similar  to
those  involved in using Forward Contracts by  purchasing put or call options on
currencies. A put option  gives an Underlying Theme  Portfolio as purchaser  the
right  (but not the  obligation) to sell  a specified amount  of currency at the
exercise price at  any time until  (American style) or  on (European style)  the
expiration date of the option. A call option gives an Underlying Theme Portfolio
as  purchaser the right (but not the  obligation) to purchase a specified amount
of currency at  the exercise  price at  any time  until (American  style) or  on
(European  style)  the  expiration  date  of  the  option.  An  Underlying Theme
Portfolio might purchase a currency put  option, for example, to protect  itself
against  a  decline in  the dollar  value of  a  currency in  which it  holds or
anticipates holding securities. If the  currency's value should decline  against
the dollar, the loss in currency value should be offset, in whole or in part, by
an increase in the value of the put. If the value of the currency instead should
rise  against the  dollar, any  gain to an  Underlying Theme  Portfolio would be
reduced by the premium it  had paid for the put  option. A currency call  option
might  be purchased, for example,  in anticipation of, or  to protect against, a
rise in the value against the dollar of a currency in which an Underlying  Theme
Portfolio anticipates purchasing securities.
 
Options  may  be either  listed  on an  exchange  or traded  in over-the-counter
("OTC") markets. Listed options are third-party contracts (I.E., performance  of
the  obligations of the  purchaser and seller  is guaranteed by  the exchange or
clearing corporation) and have standardized strike prices and expiration  dates.
OTC options are two-party contracts with negotiated strike prices and expiration
dates.  An Underlying Theme Portfolio will not  purchase an OTC option unless it
believes that  daily valuations  for such  options are  readily obtainable.  OTC
options  differ from exchange-traded options in  that OTC options are transacted
with dealers directly and not  through a clearing corporation (which  guarantees
performance).  Consequently, there is  a risk of  non-performance by the dealer.
Since no exchange is involved, OTC options are valued on the basis of an average
of the last bid prices obtained from  dealers, unless a quotation from only  one
dealer is available, in which case only that dealer's price will be used. In the
case  of OTC options, there  can be no assurance  that a liquid secondary market
will exist for any particular option at any specific time.
 
                   Statement of Additional Information Page 9
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
   
The staff of the Securities and Exchange Commission ("SEC") considers  purchased
OTC  options to be  illiquid securities. An Underlying  Theme Portfolio may also
sell OTC options  and, in connection  therewith, segregate assets  or cover  its
obligations  with respect to OTC options written by it. The assets used as cover
for OTC options  written by  an Underlying  Theme Portfolio  will be  considered
illiquid unless the OTC options are sold to qualified dealers who agree that the
Underlying  Theme Portfolio may repurchase any OTC option it writes at a maximum
price to be calculated by a formula set forth in the option agreement. The cover
for an OTC option written subject to this procedure would be considered illiquid
only to the extent that the  maximum repurchase price under the formula  exceeds
the intrinsic value of the option.
    
 
An  Underlying Theme Portfolio's ability to establish and close out positions in
exchange-listed options  depends  on the  existence  of a  liquid  market.  Each
Underlying   Theme   Portfolio  intends   to  purchase   or  write   only  those
exchange-traded options for which there appears to be a liquid secondary market.
However, there  can  be no  assurance  that such  a  market will  exist  at  any
particular  time.  Closing transactions  can  be made  for  OTC options  only by
negotiating directly with the contra party or by a transaction in the  secondary
market  if any such  market exists. Although an  Underlying Theme Portfolio will
enter into OTC options only with contra parties that are expected to be  capable
of  entering into closing transactions  with it, there is  no assurance that the
Underlying Theme Portfolio  will in  fact be  able to  close out  an OTC  option
position at a favorable price prior to expiration. In the event of insolvency of
the contra party, the Underlying Theme Portfolio might be unable to close out an
OTC option position at any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts  except that all settlements  are in cash and  gain or loss depends on
changes in the index in question (and thus on price movements in the  securities
market  or a particular market sector  generally) rather than on price movements
in  individual  securities  or  futures  contracts.  When  an  Underlying  Theme
Portfolio  writes a  call on an  index, it  receives a premium  and agrees that,
prior to the expiration date,  the purchaser of the  call, upon exercise of  the
call,  will receive from the Underlying Theme Portfolio an amount of cash if the
closing level of  the index upon  which the call  is based is  greater than  the
exercise  price  of the  call. The  amount of  cash is  equal to  the difference
between the closing price of the index and the exercise price of the call  times
a specified multiple (the "multiplier"), which determines the total dollar value
for  each point of  such difference. When  an Underlying Theme  Portfolio buys a
call on an index, it pays a premium and  has the same rights as to such call  as
are  indicated above. When an Underlying Theme Portfolio buys a put on an index,
it pays a premium and  has the right, prior to  the expiration date, to  require
the  seller of the  put, upon the  Underlying Theme Portfolio's  exercise of the
put, to deliver  to the  Underlying Theme  Portfolio an  amount of  cash if  the
closing level of the index upon which the put is based is less than the exercise
price  of the  put, which  amount of  cash is  determined by  the multiplier, as
described above for calls. When the  Underlying Theme Portfolio writes a put  on
an  index, it receives a  premium and the purchaser has  the right, prior to the
expiration date, to require the Underlying  Theme Portfolio to deliver to it  an
amount  of cash equal to  the difference between the  closing level of the index
and the exercise price times the multiplier,  if the closing level is less  than
the exercise price.
 
The  risks  of  investment in  index  options  may be  greater  than  options on
securities. Because index options are settled in cash, when an Underlying  Theme
Portfolio  writes  a call  on  an index  it cannot  provide  in advance  for its
potential  settlement  obligations  by  acquiring  and  holding  the  underlying
securities. An Underlying Theme Portfolio can offset some of the risk of writing
a  call index option  position by holding a  diversified portfolio of securities
similar to those on which the underlying index is based. However, an  Underlying
Theme  Portfolio cannot,  as a  practical matter,  acquire and  hold a portfolio
containing exactly the same securities as  underlie the index and, as a  result,
bears  a risk that the value of the  securities held will vary from the value of
the index.
 
Even if an Underlying Theme Portfolio could assemble a securities portfolio that
exactly reproduced the composition of the  underlying index, it still would  not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing  index options. When  an index option  is exercised, the  amount of cash
that the holder is entitled to  receive is determined by the difference  between
the  exercise price and the  closing index level on the  date when the option is
exercised. As with other  kinds of options, the  Underlying Theme Portfolio,  as
the call writer, will not know that it has been assigned until the next business
day  at the  earliest. The  time lag between  exercise and  notice of assignment
poses no  risk  for the  writer  of a  covered  call on  a  specific  underlying
security,  such as  common stock,  because there  the writer's  obligation is to
deliver the underlying security, not to pay its value as of a fixed time in  the
past. So long as the writer already owns the underlying security, it can satisfy
its  settlement obligations by simply delivering it, and the risk that its value
may have declined since the exercise date is borne by the exercising holder.  In
contrast,  even if  the writer  of an index  call holds  securities that exactly
match the composition of the  underlying index, it will  not be able to  satisfy
its assignment obligations by delivering those securities against payment of the
exercise  price. Instead, it will be required to  pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that  it
has been assigned, the
 
                  Statement of Additional Information Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
index  may  have declined,  with a  corresponding  decline in  the value  of its
securities portfolio.  This  "timing risk"  is  an inherent  limitation  on  the
ability of index call writers to cover their risk exposure by holding securities
positions.
 
If  an Underlying Theme Portfolio has purchased an index option and exercises it
before the closing index value for that day is available, it runs the risk  that
the  level of  the underlying  index may subsequently  change. If  such a change
causes the  exercised  option to  fall  out-of-the-money, the  Underlying  Theme
Portfolio will be required to pay the difference between the closing index value
and  the exercise price of  the option (times the  applicable multiplier) to the
assigned writer.
 
INTEREST RATE, CURRENCY AND STOCK INDEX FUTURES CONTRACTS
Each Underlying Theme Portfolio may enter into interest rate, currency or  stock
index  futures contracts (collectively,  "Futures" or "Futures  Contracts") as a
hedge against changes in prevailing levels of interest rates, currency  exchange
rates or stock price levels, respectively, in order to establish more definitely
the effective return on securities or currencies held or intended to be acquired
by  it. An Underlying Theme Portfolio's hedging  may include sales of Futures as
an offset  against the  effect  of expected  increases  in interest  rates,  and
decreases  in currency exchange rates and stock prices, and purchases of Futures
as an offset  against the  effect of expected  declines in  interest rates,  and
increases in currency exchange rates or stock prices.
 
Each  Underlying Theme Portfolio only will enter into Futures Contracts that are
traded on  futures  exchanges and  are  standardized  as to  maturity  date  and
underlying  financial instrument. Futures  exchanges and trading  thereon in the
United States are regulated  under the Commodity Exchange  Act by the  Commodity
Futures  Trading Commission  ("CFTC"). Futures  are exchanged  in London  at the
London International Financial Futures Exchange.
 
Although techniques other than sales and purchases of Futures Contracts could be
used to  reduce  an Underlying  Theme  Portfolio's exposure  to  interest  rate,
currency  exchange  rate  and  stock market  fluctuations,  an  Underlying Theme
Portfolio may be able to hedge its exposure more effectively and at a lower cost
through using Futures Contracts.
 
A Futures Contract provides  for the future  sale by one  party and purchase  by
another party of a specified amount of a specific financial instrument (security
or currency) for a specified price at a designated date, time and place. A stock
index Futures Contract provides for the delivery, at a designated date, time and
place,  of  an amount  of  cash equal  to a  specified  dollar amount  times the
difference between the stock index value at the close of trading on the contract
and the price at  which the Futures Contract  is originally struck; no  physical
delivery  of stocks  comprising the index  is made. Brokerage  fees are incurred
when a  Futures  Contract  is  bought  or sold,  and  margin  deposits  must  be
maintained at all times the Futures Contract is outstanding.
 
Although  Futures Contracts typically require future delivery of and payment for
financial instruments or  currencies, Futures Contracts  usually are closed  out
before  the delivery date. Closing out an open Futures Contract sale or purchase
is effected by entering  into an offsetting Futures  Contract purchase or  sale,
respectively,   for  the  same  aggregate  amount  of  the  identical  financial
instrument or currency and  the same delivery date.  If the offsetting  purchase
price  is  less than  the original  sale price,  the Underlying  Theme Portfolio
realizes a gain; if it is more, the Underlying Theme Portfolio realizes a  loss.
Conversely,  if the  offsetting sale  price is  more than  the original purchase
price, the  Underlying Theme  Portfolio realizes  a  gain; if  it is  less,  the
Underlying  Theme Portfolio realizes a loss.  The transaction costs must also be
included in these  calculations. There  can be  no assurance,  however, that  an
Underlying  Theme Portfolio will be able to enter into an offsetting transaction
with respect  to a  particular Futures  Contract  at a  particular time.  If  an
Underlying  Theme Portfolio is not able to enter into an offsetting transaction,
it will continue to be required to  maintain the margin deposits on the  Futures
Contract.
 
As  an example of an offsetting transaction, the contractual obligations arising
from the sale of one Futures Contract of September Deutschemarks on an  exchange
may  be fulfilled  at any  time before  delivery under  the Futures  Contract is
required (I.E., on a specified date  in September, the "delivery month") by  the
purchase  of another  Futures Contract  of September  Deutschemarks on  the same
exchange. In  such instance,  the  difference between  the  price at  which  the
Futures  Contract was sold and the price paid for the offsetting purchase, after
allowance for transaction costs, represents the profit or loss to the Underlying
Theme Portfolio.
 
Each Underlying Theme Portfolio's Futures transactions will be entered into  for
hedging  purposes; that is, Futures Contracts will  be sold to protect against a
decline in  the price  of securities  or currencies  that the  Underlying  Theme
Portfolio owns, or Futures Contracts will be purchased to protect the Underlying
Theme  Portfolio against an increase in the price of securities or currencies it
has committed to purchase or expects to purchase.
 
"Margin" with respect to Futures Contracts is  the amount of funds that must  be
deposited  by an Underlying Theme Portfolio in order to initiate Futures trading
and maintain its  open positions  in Futures  Contracts. A  margin deposit  made
 
                  Statement of Additional Information Page 11
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
when  the Futures  Contract is  entered into  ("initial margin")  is intended to
ensure the Underlying Theme Portfolio's performance under the Futures  Contract.
The  margin required for a particular Futures Contract is set by the exchange on
which the Futures Contract is traded and may be significantly modified from time
to time by the exchange during the term of the Futures Contract.
 
Subsequent  payments,  called  "variation  margin,"  to  and  from  the  futures
commission  merchant through which  the Underlying Theme  Portfolio entered into
the Futures  Contract  will be  made  on  a daily  basis  as the  price  of  the
underlying  security, currency or  index fluctuates making  the Futures Contract
more or less valuable, a process known as marking-to-market.
 
    RISKS OF  USING  FUTURES CONTRACTS.  The  prices of  Futures  Contracts  are
volatile  and  are influenced  by, among  other  things, actual  and anticipated
changes in  interest rates  and currency  exchange rates,  and in  stock  market
movements,  which  in turn  are  affected by  fiscal  and monetary  policies and
national and international political and economic events.
 
There is a risk  of imperfect correlation between  changes in prices of  Futures
Contracts  and prices  of the  securities or  currencies in  an Underlying Theme
Portfolio's portfolio being  hedged. The degree  of imperfection of  correlation
depends  upon circumstances such as variations  in speculative market demand for
Futures and  for securities  or currencies,  including technical  influences  in
Futures  trading; and differences between the financial instruments being hedged
and the  instruments underlying  the standard  Futures Contracts  available  for
trading.  A  decision of  whether,  when and  how  to hedge  involves  skill and
judgment, and even  a well-conceived hedge  may be unsuccessful  to some  degree
because of unexpected market behavior or interest or currency rate trends.
 
Because  of  the  low  margin deposits  required,  Futures  trading  involves an
extremely high  degree  of leverage.  As  a  result, a  relatively  small  price
movement  in a Futures Contract may result in immediate and substantial loss, as
well as gain, to the investor. For example,  if at the time of purchase, 10%  of
the  value of  the Futures  Contract is  deposited as  margin, a  subsequent 10%
decrease in the value of  the Futures Contract would result  in a total loss  of
the  margin  deposit, before  any deduction  for the  transaction costs,  if the
account were then closed  out. A 15%  decrease would result in  a loss equal  to
150%  of the original margin  deposit, if the Futures  Contract were closed out.
Thus, a purchase or sale of a Futures Contract may result in losses in excess of
the amount invested in the Futures Contract.
 
Most U.S. Futures exchanges limit the amount of fluctuation permitted in Futures
Contract and options on  Futures Contracts prices during  a single trading  day.
The  daily limit  establishes the  maximum amount  that the  price of  a Futures
Contract or option may vary either up or down from the previous day's settlement
price at the end of a trading session. Once the daily limit has been reached  in
a  particular type of Futures Contract or option,  no trades may be made on that
day at a price beyond  that limit. The daily  limit governs only price  movement
during  a particular trading day and  therefore does not limit potential losses,
because the limit may prevent the liquidation of unfavorable positions.  Futures
Contracts  and  option prices  have occasionally  moved to  the daily  limit for
several consecutive trading days with  little or no trading, thereby  preventing
prompt  liquidation  of positions  and  subjecting some  traders  to substantial
losses.
 
If an Underlying Theme Portfolio were unable to liquidate a Futures or option on
Futures position  due  to  the absence  of  a  liquid secondary  market  or  the
imposition  of price limits,  it could incur  substantial losses. The Underlying
Theme Portfolio would continue to be subject to market risk with respect to  the
position.  In addition, except in the  case of purchased options, the Underlying
Theme Portfolio would  continue to be  required to make  daily variation  margin
payments  and might  be required  to maintain the  position being  hedged by the
Future or option or to maintain cash or securities in a segregated account.
 
Certain characteristics  of the  Futures  market might  increase the  risk  that
movements  in the prices  of Futures Contracts  or options on  Futures might not
correlate perfectly  with  movements in  the  prices of  the  investments  being
hedged.  For example,  all participants  in the  Futures and  options on Futures
markets are subject to  daily variation margin calls  and might be compelled  to
liquidate  Futures  or  options on  Futures  positions whose  prices  are moving
unfavorably to avoid being  subject to further  calls. These liquidations  could
increase  price  volatility  of the  instruments  and distort  the  normal price
relationship between the Futures  or options and  the investments being  hedged.
Also, because initial margin deposit requirements in the Futures market are less
onerous  than  margin requirements  in the  securities  markets, there  might be
increased  participation   by  speculators   in   the  Futures   markets.   This
participation  also  might  cause  temporary  price  distortions.  In  addition,
activities of large traders in both the Futures and securities markets involving
arbitrage, "program trading"  and other  investment strategies  might result  in
temporary price distortions.
 
OPTIONS ON FUTURES CONTRACTS
Options  on Futures Contracts are similar to options on securities or currencies
except that options on Futures Contracts give the purchaser the right, in return
for the  premium paid,  to  assume a  position in  a  Futures Contract  (a  long
position if
 
                  Statement of Additional Information Page 12
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
the option is a call and a short position if the option is a put) at a specified
exercise price at any time during the period of the option. Upon exercise of the
option,  the delivery of the Futures position by the writer of the option to the
holder of the option will be accompanied by delivery of the accumulated  balance
in the writer's Futures margin account, which represents the amount by which the
market  price of the  Futures Contract, at  exercise, exceeds (in  the case of a
call) or is less than (in the case of a put) the exercise price of the option on
the Futures Contract. If an option is exercised on the last trading day prior to
the expiration date of the option, the settlement will be made entirely in  cash
equal to the difference between the exercise price of the option and the closing
level  of the securities, currencies or index upon which the Futures Contract is
based on the expiration date. Purchasers  of options who fail to exercise  their
options prior to the exercise date suffer a loss of the premium paid.
 
The  purchase of  call options  on Futures can  serve as  a long  hedge, and the
purchase of put  options on Futures  can serve  as a short  hedge. Writing  call
options  on Futures can serve as a  limited short hedge, and writing put options
on Futures can serve as a limited  long hedge, using a strategy similar to  that
used for writing options on securities, foreign currencies or indices.
 
If an Underlying Theme Portfolio writes an option on a Futures Contract, it will
be  required to  deposit initial and  variation margin  pursuant to requirements
similar to those  applicable to  Futures Contracts. Premiums  received from  the
writing  of an option on  a Futures Contract are  included in the initial margin
deposit.
 
An Underlying  Theme Portfolio  may seek  to  close out  an option  position  by
selling  an  option  covering the  same  Futures  Contract and  having  the same
exercise price  and expiration  date. The  ability to  establish and  close  out
positions  on such options is  subject to the maintenance  of a liquid secondary
market.
 
LIMITATIONS ON  USE  OF FUTURES,  OPTIONS  ON  FUTURES AND  CERTAIN  OPTIONS  ON
CURRENCIES
To  the extent that an Underlying Theme Portfolio enters into Futures Contracts,
options on  Futures Contracts  and options  on foreign  currencies traded  on  a
CFTC-regulated  exchange, in each case other than for bona fide hedging purposes
(as defined by the CFTC), the aggregate initial margin and premiums required  to
establish   those  positions  (excluding   the  amount  by   which  options  are
"in-the-money") will not exceed  5% of the liquidation  value of the  Underlying
Theme  Portfolio, after  taking into  account unrealized  profits and unrealized
losses on any  contracts it has  entered into. In  general, a call  option on  a
Futures  Contract  is  "in-the-money" if  the  value of  the  underlying Futures
Contract exceeds the strike, I.E., exercise, price of the call; a put option  on
a  Futures Contract  is "in-the-money"  if the  value of  the underlying Futures
Contract is exceeded  by the  strike price  of the  put. This  guideline may  be
modified  by the applicable  Board, without a  shareholder vote. This limitation
does not limit the percentage of an Underlying Theme Portfolio's assets at  risk
to 5%.
 
FORWARD CURRENCY CONTRACTS
A Forward Currency Contract is an obligation, usually arranged with a commercial
bank  or other currency dealer,  to purchase or sell  a currency against another
currency at a future date and price as agreed upon by the parties. An Underlying
Theme Portfolio  either may  accept or  make  delivery of  the currency  at  the
maturity of the Forward Contract. An Underlying Theme Portfolio may also, if its
contra  party  agrees  prior  to  maturity,  enter  into  a  closing transaction
involving the purchase or sale of an offsetting contract.
 
An Underlying  Theme  Portfolio  engages in  forward  currency  transactions  in
anticipation  of, or to protect itself  against, fluctuations in exchange rates.
An Underlying Theme Portfolio might sell a particular foreign currency  forward,
for  example,  when  it  holds  bonds  denominated  in  a  foreign  currency but
anticipates, and  seeks to  be  protected against,  a  decline in  the  currency
against the U.S. dollar. Similarly, an Underlying Theme Portfolio might sell the
U.S.  dollar  forward  when  it  holds bonds  denominated  in  U.S.  dollars but
anticipates, and seeks  to be protected  against, a decline  in the U.S.  dollar
relative  to  other currencies.  Further,  an Underlying  Theme  Portfolio might
purchase a currency forward to "lock in" the price of securities denominated  in
that currency that it anticipates purchasing.
 
Forward Currency Contracts are traded in the interbank market conducted directly
between currency traders (usually large commercial banks) and their customers. A
Forward  Contract generally has  no deposit requirement,  and no commissions are
charged at any stage for trades. Each Underlying Theme Portfolio will enter into
such Forward  Contracts with  major  U.S. or  foreign  banks and  securities  or
currency dealers in accordance with guidelines approved by the applicable Board.
 
An  Underlying  Theme Portfolio  may enter  into  Forward Contracts  either with
respect to specific transactions or with respect to overall investments of  that
Underlying Theme Portfolio. The precise matching of the Forward Contract amounts
and  the value of specific securities generally will not be possible because the
future value  of  such  securities  in  foreign  currencies  will  change  as  a
consequence  of market  movements in the  value of those  securities between the
date the Forward Contract is entered into and the date it matures.  Accordingly,
it may be necessary for that Underlying Theme
 
                  Statement of Additional Information Page 13
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Portfolio  to  purchase additional  foreign currency  on  the spot  (I.E., cash)
market (and  bear the  expense of  such purchase)  if the  market value  of  the
security  is  less than  the  amount of  foreign  currency the  Underlying Theme
Portfolio is obligated to deliver and if a decision is made to sell the security
and make delivery of  the foreign currency. Conversely,  it may be necessary  to
sell  on  the spot  market some  of  the foreign  currency the  Underlying Theme
Portfolio is obligated to deliver. The projection of short-term currency  market
movements  is extremely difficult, and the  successful execution of a short-term
hedging strategy is highly  uncertain. Forward Contracts  involve the risk  that
anticipated  currency  movements will  not be  predicted accurately,  causing an
Underlying Theme Portfolio to sustain losses on these contracts and  transaction
costs.
 
At  or before the maturity  of a Forward Contract  requiring an Underlying Theme
Portfolio to sell a  currency, it either  may sell a security  and use the  sale
proceeds  to make delivery of the currency or retain the security and offset its
contractual obligation to deliver the  currency by purchasing a second  contract
pursuant  to which it will obtain, on the same maturity date, the same amount of
the currency that  it is obligated  to deliver. Similarly,  an Underlying  Theme
Portfolio  may close out a Forward Contract requiring it to purchase a specified
currency by,  if  its contra  party  agrees,  entering into  a  second  contract
entitling  it to sell the same amount of  the same currency on the maturity date
of the first  contract. An Underlying  Theme Portfolio would  realize a gain  or
loss  as a  result of  entering into such  an offsetting  Forward Contract under
either circumstance  to  the extent  the  exchange  rate or  rates  between  the
currencies  involved moved between the execution dates of the first contract and
the offsetting contract.
 
The cost  to an  Underlying Theme  Portfolio of  engaging in  Forward  Contracts
varies  with factors such as the currencies involved, the length of the contract
period and the market conditions then prevailing. Because Forward Contracts  are
usually  entered into on a principal basis, no fees or commissions are involved.
The use of Forward  Contracts does not eliminate  fluctuations in the prices  of
the  underlying  securities an  Underlying Theme  Portfolio  owns or  intends to
acquire, but it does establish a rate of exchange in advance. In addition, while
Forward Contract sales limit the risk of loss  due to a decline in the value  of
the  hedged currencies,  they also  limit any  potential gain  that might result
should the value of the currencies increase.
 
FOREIGN CURRENCY STRATEGIES -- SPECIAL CONSIDERATIONS
An Underlying Theme Portfolio may use options on foreign currencies, Futures  on
foreign  currencies,  options  on  Futures  on  foreign  currencies  and Forward
Contracts to hedge against movements in the values of the foreign currencies  in
which the Underlying Theme Portfolio's securities are denominated. Such currency
hedges  can protect  against price movements  in a security  that the Underlying
Theme Portfolio owns or intends to  acquire that are attributable to changes  in
the  value  of the  currency in  which it  is denominated.  Such hedges  do not,
however, protect against price movements in the securities that are attributable
to other causes.
 
An Underlying Theme Portfolio might seek  to hedge against changes in the  value
of  a particular currency  when no Futures Contract,  Forward Contract or option
involving that currency is available or one of such contracts is more  expensive
than  certain other contracts. In such cases, the Underlying Theme Portfolio may
hedge against price movements  in that currency by  entering into a contract  on
another  currency  or basket  of  currencies, the  values  of which  the Manager
believes will have  a positive correlation  to the value  of the currency  being
hedged.  The risk that movements in the price of the contract will not correlate
perfectly with movements in the price of the currency being hedged is  magnified
when this strategy is used.
 
The  value of Futures Contracts, options on Futures Contracts, Forward Contracts
and options  on  foreign currencies  depends  on  the value  of  the  underlying
currency  relative  to the  U.S. dollar.  Because foreign  currency transactions
occurring in the  interbank market  might involve  substantially larger  amounts
than  those  involved in  the  use of  Futures  Contracts, Forward  Contracts or
options, the Underlying Theme Portfolio could be disadvantaged by dealing in the
odd lot market (generally  consisting of transactions of  less than $1  million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
There is no systematic reporting of last sale information for foreign currencies
or  any  regulatory requirements  that quotations  available through  dealers or
other market sources be firm or revised on a timely basis. Quotation information
generally is representative of very  large transactions in the interbank  market
and  thus  might not  reflect  odd-lot transactions  where  rates might  be less
favorable.  The   interbank  market   in  foreign   currencies  is   a   global,
round-the-clock  market. To the  extent the U.S. options  or Futures markets are
closed while the markets for the underlying currencies remain open,  significant
price  and rate movements might take place in the underlying markets that cannot
be reflected in  the markets  for the Futures  contracts or  options until  they
reopen.
 
                  Statement of Additional Information Page 14
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
Settlement of Futures Contracts, Forward Contracts and options involving foreign
currencies  might  be required  to  take place  within  the country  issuing the
underlying currency. Thus, an  Underlying Theme Portfolio  might be required  to
accept  or make delivery  of the underlying foreign  currency in accordance with
any U.S. or  foreign regulations  regarding the maintenance  of foreign  banking
arrangements  by U.S. residents and might be required to pay any fees, taxes and
charges associated with such delivery assessed in the issuing country.
 
COVER
Transactions using Forward Contracts, Futures Contracts and options (other  than
options  that an Underlying Theme Portfolio has purchased) expose the Underlying
Theme Portfolio to an obligation to another party. An Underlying Theme Portfolio
will not  enter  into  any  such  transactions unless  it  owns  either  (1)  an
offsetting  ("covered") position  in securities,  currencies, or  other options,
Forward Contracts or Futures Contracts  or (2) cash, receivables and  short-term
debt  securities with  a value  sufficient at all  times to  cover its potential
obligations not  covered  as  provided  in  (1)  above.  Each  Underlying  Theme
Portfolio  will comply with SEC guidelines regarding cover for these instruments
and, if the guidelines so require, set aside cash or liquid securities.
 
Assets used as cover or  held in a segregated account  cannot be sold while  the
position  in the corresponding  Forward Contract, Futures  Contract or option is
open, unless they are replaced with other appropriate assets. If a large portion
of an Underlying  Theme Portfolio's assets  is used for  cover or otherwise  set
aside,  it could affect portfolio management or the Underlying Theme Portfolio's
ability to meet redemption requests or other current obligations.

                              RISK FACTORS OF THE
                          UNDERLYING THEME PORTFOLIOS
 
- --------------------------------------------------------------------------------
 
DEBT SECURITIES
The value  of  the debt  securities  held  by each  Underlying  Theme  Portfolio
generally  will vary conversely with market interest rates. If interest rates in
a market fall, the value  of the debt securities  held by each Underlying  Theme
Portfolio  ordinarily will rise. If market interest rates increase, however, the
debt securities owned by each Underlying Theme Portfolio in that market will  be
likely to decrease in value.
 
The  Global  Consumer  Products and  Services  Portfolio,  Global Infrastructure
Portfolio, and Global Natural Resources Portfolio  may each invest up to 20%  of
its  total  assets  in  debt  securities  rated  below  investment  grade.  Such
investments involve a high  degree of risk. However,  those Portfolios will  not
invest  in debt securities  that are in  default as to  payment of principal and
interest.
 
Debt rated Baa  by Moody's Investors  Service, Inc. ("Moody")  is considered  by
Moody's  to have speculative characteristics. Debt rated  BB, B, CCC, CC or C by
Standard & Poor's, a  division of The McGraw-Hill  Companies, Inc. ("S&P"),  and
debt  rated  Ba,  B,  Caa, Ca  or  C  by  Moody's is  regarded,  on  balance, as
predominantly speculative with respect to the issuer's capacity to pay  interest
and  repay principal in accordance with the terms of the obligation. For S&P, BB
indicates the lowest degree of speculation for such lower quality debt and C the
highest degree of speculation. For Moody's,  Baa indicates the lowest degree  of
speculation for such lower quality debt and C the highest degree of speculation.
While  such  lower quality  debt will  likely have  some quality  and protective
characteristics, these  are  outweighed by  large  uncertainties or  major  risk
exposures  to adverse conditions. Debt  rated C by Moody's  or S&P is the lowest
rated debt that is  not in default  as to principal or  interest, and issues  so
rated  can be regarded as having extremely  poor prospects of ever attaining any
real investment  standing.  Lower quality  debt  securities also  are  generally
considered  to be  subject to greater  risk than securities  with higher ratings
with regard  to a  deterioration  of general  economic conditions.  These  lower
quality  debt  securities are  the equivalent  of high  yield, high  risk bonds,
commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality and are not a guarantee of quality. Rating agencies attempt to  evaluate
the  safety of principal and interest payments  and do not evaluate the risks of
fluctuations in market  value. Also,  rating agencies  may fail  to make  timely
changes  in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than a rating indicates.
 
The market values of  lower quality debt securities  tend to reflect  individual
developments  of  the  issuer  to  a  greater  extent  than  do  higher  quality
securities, which  react  primarily to  fluctuations  in the  general  level  of
interest rates. In addition,
 
                  Statement of Additional Information Page 15
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
lower  quality debt securities tend to  be more sensitive to economic conditions
and generally have more volatile prices than higher quality securities.  Issuers
of  lower  quality  securities  are  often highly  leveraged  and  may  not have
available to them more traditional methods of financing. For example, during  an
economic  downturn  or  a  sustained period  of  rising  interest  rates, highly
leveraged issuers of lower quality  securities may experience financial  stress.
During such periods, such issuers may not have sufficient revenues to meet their
interest   payment  obligations.  The  issuer's  ability  to  service  its  debt
obligations may also  be adversely affected  by specific developments  affecting
the  issuer, such as the issuer's  inability to meet specific projected business
forecasts or the unavailability of additional financing. The risk of loss due to
default by the issuer is significantly greater for the holders of lower  quality
securities   because  such  securities  are   generally  unsecured  and  may  be
subordinated to the claims of other creditors of the issuer.
 
Lower quality  debt securities  of  corporate issuers  frequently have  call  or
buy-back features that permit the issuer to call or repurchase the security from
an  Underlying Theme  Portfolio. If  an issuer  exercises these  provisions in a
declining interest  rate market,  the  Underlying Theme  Portfolio may  have  to
replace  the security with  a lower yielding security,  resulting in a decreased
return for  investors. In  addition, the  Underlying Theme  Portfolios may  have
difficulty  disposing of lower  quality securities because they  may have a thin
trading market. There may be no established retail secondary market for many  of
these  securities,  and each  Underlying Theme  Portfolio anticipates  that such
securities could be sold  only to a limited  number of dealers or  institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on  market prices  of such instruments  and may  make it more  difficult for the
Underlying Theme Portfolios to obtain accurate market quotations for purposes of
valuing their portfolio  investments. The Underlying  Theme Portfolios may  also
acquire  lower quality debt  securities during an  initial underwriting or which
are sold without registration under applicable securities laws. Such  securities
involve special considerations and risks.
 
In  addition to the foregoing, factors that  could have an adverse effect on the
market value of  lower quality  debt securities  in which  the Underlying  Theme
Portfolios  may invest include: (i) potential adverse publicity; (ii) heightened
sensitivity to general economic  or political conditions;  and (iii) the  likely
adverse  impact of a major economic recession. An Underlying Theme Portfolio may
also incur additional  expenses to the  extent it is  required to seek  recovery
upon  a default in the  payment of principal or  interest on portfolio holdings,
and the Underlying Theme Portfolio may have limited legal recourse in the  event
of a default.
 
The   Manager  attempts  to  minimize  the  speculative  risks  associated  with
investments in lower quality securities through credit analysis and by carefully
monitoring current trends  in interest rates,  political developments and  other
factors.
 
ILLIQUID SECURITIES
Each  Underlying Theme Portfolio may invest up  to 15% of its net assets (except
for the Health Care  Fund, which may invest  up to 10% of  its total assets)  in
illiquid  securities.  Securities may  be considered  illiquid if  an Underlying
Theme  Portfolio  cannot  reasonably  expect  within  seven  days  to  sell  the
securities  for approximately the amount at which it values such securities. See
"Investment Limitations of the Underlying Theme Funds and Portfolios." The  sale
of  illiquid securities, if they can be sold at all, generally will require more
time and  result in  higher  brokerage charges  or  dealer discounts  and  other
selling  expenses than  will the  sale of  liquid securities  such as securities
eligible for trading on U.S. securities  exchanges or in OTC markets.  Moreover,
restricted  securities, which may  be illiquid for  purposes of this limitation,
often sell, if at  all, at a  price lower than similar  securities that are  not
subject to restrictions on resale.
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, an Underlying Theme Portfolio may be obligated to pay
all or part of  the registration expenses and  a considerable period may  elapse
between  the time  of the  decision to  sell and  the time  the Underlying Theme
Portfolio may be permitted  to sell a security  under an effective  registration
statement.  If, during such a period, adverse market conditions were to develop,
the Underlying  Theme  Portfolio  might  obtain  a  less  favorable  price  than
prevailed when it decided to sell.
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under  the Securities  Act  of 1933,  as  amended (the  "1933 Act"),
including private placements, repurchase  agreements, commercial paper,  foreign
securities and corporate bonds and notes. These instruments are often restricted
securities  because  the  securities  are  sold  in  transactions  not requiring
registration. Institutional  investors generally  will not  seek to  sell  these
instruments  to the general public,  but instead will often  depend either on an
efficient institutional  market in  which such  unregistered securities  can  be
readily  resold  or on  an issuer's  ability  to honor  a demand  for repayment.
Therefore, the fact that there are  contractual or legal restrictions on  resale
to  the  general  public  or  certain institutions  is  not  dispositive  of the
liquidity of such investments.

Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the  1933 Act  for resales  of certain  securities to qualified
institutional buyers.  Institutional  markets  for  restricted  securities  have
developed  as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to  satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance  and  settlement of  unregistered securities  of domestic  and foreign
issuers, such as  the PORTAL  System sponsored  by the  National Association  of
Securities  Dealers,  Inc.  An insufficient  number  of  qualified institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
an Underlying Theme Portfolio, however, could affect adversely the marketability
of such portfolio securities, and the Underlying Theme Portfolio might be unable
to dispose of such securities promptly or at favorable prices.
 
With respect to liquidity determinations generally, the applicable Board has the
ultimate responsibility for determining  whether specific securities,  including
restricted  securities pursuant to Rule  144A under the 1933  Act, are liquid or
illiquid.  Each  Board   has  delegated  the   function  of  making   day-to-day
determinations  of  liquidity  to  the Manager,  in  accordance  with procedures
approved by that Board. The  Manager takes into account  a number of factors  in
reaching  liquidity decisions,  including (i)  the frequency  of trading  in the
security, (ii) the number  of dealers that make  quotes for the security,  (iii)
the  number of dealers  that have undertaken  to make a  market in the security,
(iv) the number of other potential purchasers and (v) the nature of the security
and how trading is  effected (e.g., the  time needed to  sell the security,  how
offers  are solicited and  the mechanics of transfer).  The Manager monitors the
liquidity of securities held by each Underlying Theme Portfolio and periodically
reports such determinations to the  applicable Board. The Manager believes  that
carefully selected investments in joint ventures, cooperatives, partnerships and
state  enterprises that are illiquid  (collectively, "Special Situations") could
enable  an   Underlying  Theme   Portfolio  to   achieve  capital   appreciation
substantially  exceeding the  appreciation it would  realize if it  did not make
such investments. However, in  order to attempt to  limit investment risk,  each
Underlying  Theme Portfolio will invest  no more than 5%  of its total assets in
Special Situations.
 
FOREIGN SECURITIES
    POLITICAL, SOCIAL AND  ECONOMIC RISKS. Investing  in securities of  non-U.S.
companies may entail additional risks due to the potential political, social and
economic  instability  of  certain  countries and  the  risks  of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment convertibility of currencies into U.S. dollars and on repatriation of
capital  invested. In the event of  such expropriation, nationalization or other
confiscation by any country, an Underlying Theme Portfolio could lose its entire
investment in any such country.
 
    RELIGIOUS, POLITICAL AND ETHNIC INSTABILITY.  Certain countries in which  an
Underlying  Theme Portfolio  may invest  may have  groups that  advocate radical
religious or  revolutionary philosophies  or  support ethnic  independence.  Any
disturbance  on  the part  of  such individuals  could  carry the  potential for
widespread destruction  or confiscation  of property  owned by  individuals  and
entities foreign to such country and could cause the loss of an Underlying Theme
Portfolio's  investment in  those countries.  Instability may  also result from,
among other things,  (i) authoritarian  governments or  military involvement  in
political  and economic decision-making, including changes in government through
extra-constitutional means,  (ii) popular  unrest  associated with  demands  for
improved  political, economic and social conditions; and (iii) hostile relations
with neighboring  or  other  countries.  Such  political,  social  and  economic
instability could disrupt the principal financial markets in which an Underlying
Theme Portfolio invests and adversely affect the value of its assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial restrictions on investments  in their capital markets,  particularly
their equity markets, by foreign entities such as an Underlying Theme Portfolio.
These  restrictions or  controls may at  times limit or  preclude investments in
certain securities and may increase the cost and expenses of an Underlying Theme
Portfolio. For example,  certain countries require  prior governmental  approval
before  investments by foreign  persons may be  made or may  limit the amount of
investment by foreign persons in a particular company or limit the investment by
foreign persons to only  a specific class  of securities of  a company that  may
have  less  advantageous  terms than  securities  of the  company  available for
purchase by nationals. Moreover, the national policies of certain countries  may
restrict  investment opportunities in issuers  or industries deemed sensitive to
national interests. In  addition, some countries  require governmental  approval
for the repatriation of investment income, capital or the proceeds of securities
sales  by  foreign investors.  In addition,  if  there is  a deterioration  in a
country's balance  of  payments or  for  other  reasons, a  country  may  impose
restrictions   on  foreign  capital  remittances  abroad.  An  Underlying  Theme
Portfolio could be adversely affected by delays  in, or a refusal to grant,  any
required  governmental approval for repatriation, as  well as by the application
to it of other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION. Foreign companies are subject to accounting, auditing and  financial
standards  and requirements that differ, in some cases significantly, from those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing   on   the    financial   statements   of    such   a   company    may
 
                  Statement of Additional Information Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
not  reflect its  financial position  or results of  operations in  the way they
would be reflected  had such  financial statements been  prepared in  accordance
with  U.S. generally accepted accounting principles. Most of the securities held
by an  Underlying  Theme  Portfolio will  not  be  registered with  the  SEC  or
regulators  of any foreign country,  nor will the issuers  thereof be subject to
the SEC's reporting requirements. Thus, there will be less available information
concerning most  foreign  issuers of  securities  held by  an  Underlying  Theme
Portfolio  than is  available concerning  U.S. issuers.  In instances  where the
financial statements  of an  issuer are  not deemed  to reflect  accurately  the
financial  situation of the  issuer, the Manager will  take appropriate steps to
evaluate the proposed investment,  which may include  on-site inspection of  the
issuer,  interviews  with  its management  and  consultations  with accountants,
bankers and other  specialists. There is  substantially less publicly  available
information about foreign companies than there are reports and ratings published
about U.S. companies. In addition, where public information is available, it may
be  less  reliable  than such  information  regarding U.S.  issuers.  Issuers of
securities in foreign jurisdictions are generally not subject to the same degree
of regulation as are U.S. issuers  with respect to such matters as  restrictions
on  market manipulation,  insider trading rules,  shareholder proxy requirements
and timely disclosure of information.
 
    CURRENCY FLUCTUATIONS. Because each Underlying Theme Portfolio, under normal
circumstances, will invest  a substantial  portion of  its total  assets in  the
securities  of foreign issuers  that are denominated  in foreign currencies, the
strength or weakness  of the U.S.  dollar against such  foreign currencies  will
account  for part of  an Underlying Theme  Portfolio's investment performance. A
decline in the  value of any  particular currency against  the U.S. dollar  will
cause  a decline  in the  U.S. dollar value  of an  Underlying Theme Portfolio's
holdings of securities  and cash  denominated in that  currency and,  therefore,
will  cause an overall  decline in its  and its corresponding  Feeder Fund's net
asset value (as  applicable) and  any net  investment income  and capital  gains
derived  from  such  securities  to  be  distributed  in  U.S.  dollars  to  the
shareholders thereof. Moreover, if the value of the foreign currencies in  which
an  Underlying Theme  Portfolio receives its  income falls relative  to the U.S.
dollar between  receipt of  the  income and  the  making of  distributions,  the
Underlying  Theme Portfolio  may be required  to liquidate securities  if it has
insufficient cash in U.S. dollars to meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors, including the supply  and demand for particular currencies,
central bank efforts to support particular currencies, the relative movement  of
interest  rates, and pace  of business activity  in the other  countries and the
United States, and other economic  and financial conditions affecting the  world
economy.
 
Although  each Underlying  Theme Portfolio values  its assets daily  in terms of
U.S. dollars, the  Underlying Theme Portfolios  do not intend  to convert  their
holdings  of  foreign  currencies  into  U.S. dollars  on  a  daily  basis. Each
Underlying Theme Portfolio will do so,  from time to time, and investors  should
be  aware of the costs of currency conversion. Although foreign exchange dealers
do not  charge a  fee for  conversion, they  do realize  a profit  based on  the
difference  ("spread") between  the prices  at which  they buy  and sell various
currencies. Thus, a dealer may offer to sell a foreign currency to an Underlying
Theme Portfolio at one rate, while offering a lesser rate of exchange should  an
Underlying Theme Portfolio desire to sell that currency to the dealer.
 
    ADVERSE  MARKET CHARACTERISTICS. Securities  of many foreign  issuers may be
less liquid and their  prices more volatile than  securities of comparable  U.S.
issuers.  In  addition, foreign  securities  markets and  brokers  generally are
subject to  less governmental  supervision  and regulation  than in  the  United
States,  and  foreign  securities  transactions  usually  are  subject  to fixed
commissions, which  generally are  higher than  negotiated commissions  on  U.S.
transactions.  In addition,  foreign securities  transactions may  be subject to
difficulties associated  with the  settlement of  such transactions.  Delays  in
settlement  could result in temporary periods when assets of an Underlying Theme
Portfolio are uninvested and  no return is earned  thereon. The inability of  an
Underlying Theme Portfolio to make intended security purchases due to settlement
problems  could cause it to  miss attractive investment opportunities. Inability
to dispose  of a  portfolio security  due to  settlement problems  either  could
result  in losses to an Underlying Theme Portfolio due to subsequent declines in
value of  the portfolio  security or,  if that  Underlying Theme  Portfolio  has
entered into a contract to sell the security, could result in possible liability
to  the purchaser. The Manager will  consider such difficulties when determining
the allocation of an Underlying  Theme Portfolio's assets, although the  Manager
does  not believe that such difficulties will  have a material adverse effect on
an Underlying Theme Portfolio's portfolio trading activities.
 
Each Underlying Theme Portfolio  may use foreign  custodians, which may  involve
risks  in addition to  those related to  its use of  U.S. custodians. Such risks
include uncertainties relating  to (1)  determining and  monitoring the  foreign
custodian's   financial  strength,  reputation  and  standing,  (2)  maintaining
appropriate safeguards concerning an  Underlying Theme Portfolio's  investments,
and  (3) possible difficulties in obtaining and enforcing judgments against such
custodians.
 
                  Statement of Additional Information Page 18
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
   
    WITHHOLDING TAXES. Each Underlying  Theme Portfolio's net investment  income
from  securities of foreign issuers  may be subject to  withholding taxes by the
foreign issuer's country, thereby reducing  that income or delaying the  receipt
of income when those taxes may be recaptured. See "Taxes."
    
 
    CONCENTRATION.  To  the  extent  an  Underlying  Theme  Portfolio  invests a
significant portion  of  its  assets  in securities  of  issuers  located  in  a
particular  country or region of  the world, it may  be subject to greater risks
and may  experience  greater  volatility  than  a  fund  that  is  more  broadly
diversified geographically.
 
    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Belgium,
Denmark,  France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg, Netherlands,
Portugal, Spain, and the United  Kingdom) eliminated certain import tariffs  and
quotas  and  other trade  barriers with  respect  to one  another over  the past
several years. The Manager  believes that this  deregulation should improve  the
prospects  for economic growth  in many Western  European countries. Among other
things, the  deregulation could  enable companies  domiciled in  one country  to
avail  themselves of lower labor costs existing in other countries. In addition,
this deregulation could benefit  companies domiciled in  one country by  opening
additional  markets  for their  goods and  services  in other  countries. Since,
however, it is not clear  what the exact form or  effect of these Common  Market
reforms  will be on business in Western  Europe, it is impossible to predict the
long-term impact of the implementation of these programs on the securities owned
by an Underlying Theme Portfolio.
 
    SPECIAL   CONSIDERATIONS    AFFECTING    RUSSIA   AND    EASTERN    EUROPEAN
COUNTRIES.  Investing in Russia  and Eastern European  countries involves a high
degree  of  risk  and  special  considerations  not  typically  associated  with
investing  in  the  U.S.  securities markets  and  should  be  considered highly
speculative. Such risks include the following: (1) delays in settling  portfolio
transactions  and risk of loss  arising out of the  system of share registration
and custody; (2) the risk  that it may be impossible  or more difficult than  in
other  countries  to  obtain and/or  enforce  a judgment;  (3)  pervasiveness of
corruption and  crime  in  the  economic  system;  (4)  currency  exchange  rate
volatility  and the lack  of available currency  hedging instruments; (5) higher
rates of inflation (including the risk of social unrest associated with  periods
of  hyper-inflation) and high  unemployment; (6) controls  on foreign investment
and  local   practices  disfavoring   foreign  investors   and  limitations   on
repatriation of invested capital, profits and dividends, and on a fund's ability
to  exchange local  currencies for U.S.  dollars; (7)  political instability and
social unrest and  violence; (8)  the risk that  the governments  of Russia  and
Eastern  European countries may  decide not to continue  to support the economic
reform programs  implemented  recently  and  could  follow  radically  different
political  and/or  economic policies  to the  detriment of  investors, including
non-market-oriented policies such as  the support of  certain industries at  the
expense  of other  sectors or  investors, or a  return to  the centrally planned
economy that existed when such countries had a communist form of government; (9)
the financial condition of companies in these countries, including large amounts
of inter-company debt which  may create a payments  crisis on a national  scale;
(10)  dependency on  exports and  the corresponding  importance of international
trade; (11) the risk that the tax system in these countries will not be reformed
to prevent inconsistent,  retroactive and/or exorbitant  taxation; and (12)  the
underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly  since 1990. The general government position has deteriorated as a
result of weakening economic  growth and stimulative  measures taken to  support
economic  activity and to  restore financial stability.  Although the decline in
interest  rates  and  fiscal  stimulation   packages  have  helped  to   contain
recessionary  forces, uncertainties remain. Japan is also heavily dependent upon
international trade, so its  economy is especially  sensitive to trade  barriers
and  disputes.  Japan has  had difficult  relations  with its  trading partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible that  trade sanctions  and other  protectionist measures  could  impact
Japan adversely in both the short and the long term.
 
The  common  stocks  of many  Japanese  companies trade  at  high price-earnings
ratios. Differences  in accounting  methods  make it  difficult to  compare  the
earnings  of  Japanese companies  with those  of  companies in  other countries,
especially in the  United States. In  general, however, reported  net income  in
Japan  is  understated relative  to U.S.  accounting standards  and this  is one
reason why price-earnings ratios of the stocks of Japanese companies have tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally been  lower than in  the United  States,
both   factors  which  tend  to  result  in  lower  discount  rates  and  higher
price-earnings ratios in Japan than in the United States.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.

                          GT GLOBAL NEW DIMENSION FUND
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes  also exist  between  South Korea  and North  Korea.  In
addition,  some Underlying Theme Portfolios intend to invest in Hong Kong, which
reverted to Chinese administration on July 1, 1997. Investments in Hong Kong may
be subject to expropriation, nationalization  or confiscation, in which case  an
Underlying  Theme Portfolio  could lose its  entire investment in  Hong Kong. In
addition, the reversion of  Hong Kong also  presents a risk  that the Hong  Kong
dollar  will be devalued and  a risk of possible  loss of investor confidence in
Hong Kong's currency, stock market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American  countries have experienced substantial,  and in some periods extremely
high, rates of  inflation for many  years. Inflation and  rapid fluctuations  in
inflation  rates have had and may continue  to have very negative effects on the
economies and securities  markets of certain  Latin American countries.  Certain
Latin  American countries are also among the largest debtors to commercial banks
and foreign governments. At times certain Latin American countries have declared
moratoria on  the payment  of principal  and/or interest  on external  debt.  In
addition,  certain  Latin  American  securities  markets  have  experienced high
volatility in recent years.
 
Latin American countries may  also close certain sectors  of their economies  to
equity  investments  by foreigners.  Further due  to  the absence  of securities
markets and  publicly  owned corporations  and  due to  restrictions  on  direct
investment  by foreign entities,  investments may only be  made in certain Latin
American  countries  solely   or  primarily   through  governmentally   approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at  artificial levels to the U.S. dollar rather than at levels determined by the
market. This type  of system can  lead to  sudden and large  adjustments in  the
currency  which, in turn, can  have a disruptive and  negative effect on foreign
investors. For example, in late  1994, the value of  the Mexican peso lost  more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL   CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in  the
securities of companies in emerging markets may entail special risks relating to
potential political and  economic instability  and the  risks of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment, convertibility of currencies into  U.S. dollars and on  repatriation
of  capital invested.  In the  event of  such expropriation,  nationalization or
other confiscation by any country, an Underlying Theme Portfolio could lose  its
entire investment in any such country.
 
Emerging  securities  markets are  substantially  smaller, less  developed, less
liquid and more volatile than the major securities markets. The limited size  of
emerging securities markets and limited trading value in issuers compared to the
volume  of  trading in  U.S. securities  could  cause prices  to be  erratic for
reasons apart  from factors  that  affect the  quality  of the  securities.  For
example, limited market size may cause prices to be unduly influenced by traders
who  control  large  positions. Adverse  publicity  and  investors' perceptions,
whether or  not  based on  fundamental  analysis,  may decrease  the  value  and
liquidity  of portfolio  securities, especially  in these  markets. In addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience of financial intermediaries, a lack of modern technology, the  lack
of  a sufficient capital base to expand business operations, and the possibility
of permanent or temporary termination of trading.
 
Settlement mechanisms in emerging securities  markets may be less efficient  and
reliable  than in more developed markets.  In such emerging securities there may
be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and  may  continue to  have  negative effects  on  the economies  and securities
markets of certain emerging market countries.
 
    PRIVATIZATIONS. The governments of some foreign countries have been  engaged
in  programs  of selling  part or  all of  their stakes  in government  owned or
controlled   enterprises   ("privatizations").   The   Manager   believes   that
privatizations  may offer opportunities for significant capital appreciation and
intends to invest assets of the Underlying Theme Portfolios in privatizations in
appropriate circumstances. In certain foreign countries, the ability of  foreign
entities   such   as  the   Underlying  Theme   Portfolios  to   participate  in
privatizations may be limited by local law, or the terms on which the Underlying
Theme Portfolios may be permitted to  participate may be less advantageous  than
those  for local investors.  There can be no  assurance that foreign governments
will continue to sell  companies currently owned or  controlled by them or  that
privatization programs will be successful.

                             INVESTMENT LIMITATIONS
 
- --------------------------------------------------------------------------------
 
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. 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.

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 Global Infrastructure  Portfolio's
    and  Global Natural Resources Portfolio's  total assets, such Portfolio will
    not make any additional investments); and
    
 
        (8) Invest  more  than  10% of  its  total  assets in  shares  of  other
    investment  companies and may not invest more than 5% of its total assets in
    any one investment company or acquire more than 3% of the outstanding voting
    securities of any one investment company.
 
Investors should refer  to the  Underlying Theme Funds'  prospectus for  further
information  with respect to the investment objective of each Feeder Fund, which
may  not  be  changed  without  the  approval  of  its  shareholders,  and   its
corresponding Portfolio's investment objective, which may be changed without the
approval  of its interestholders, and  other investment policies, techniques and
limitations, which may or may not be changed without interestholder approval.
 
HEALTH CARE FUND
 
The Health  Care  Fund  has  adopted the  following  investment  limitations  as
fundamental  policies, which (unless otherwise noted) may not be changed without
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

                          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.
 
                  Statement of Additional Information Page 26
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
Investment  decisions for an Underlying Theme Portfolio and for other investment
accounts managed by the Manager are made independently of each other in light of
differing conditions. However, the same investment decision occasionally may  be
made  for two or more of such accounts, including an Underlying Theme Portfolio.
In such cases, simultaneous transactions may occur. Purchases or sales are  then
allocated  as to price  or amount in a  manner deemed fair  and equitable to all
accounts involved. While in  some cases this practice  could have a  detrimental
effect  upon the price  or value of the  security as far  as an Underlying Theme
Portfolio is concerned, in  other cases the  Manager believes that  coordination
and the ability to participate in volume transactions will be beneficial to that
Underlying Theme Portfolio.
 
Under  a policy adopted  by the applicable  Board, and subject  to the policy of
obtaining the best net results, the Manager may consider a broker/dealer's  sale
of  the shares of the Underlying Theme  Funds and the other portfolios for which
the  Manager  serves  as  investment  manager  or  administrator  in   selecting
broker/dealers for the execution of portfolio transactions. This policy does not
imply  a commitment to execute portfolio transactions through all broker/dealers
that sell shares of the Underlying Theme Funds and such other portfolios.
 
Each Underlying  Theme Portfolio  contemplates  purchasing most  foreign  equity
securities  in OTC markets or stock exchanges  located in the countries in which
the respective principal offices  of the issuers of  the various securities  are
located,  if that is  the best available  market. The fixed  commissions paid in
connection with most such foreign  stock transactions generally are higher  than
negotiated  commissions on U.S. transactions. There generally is less government
supervision and regulation of  foreign stock exchanges and  brokers than in  the
United  States. Foreign security settlements may in some instances be subject to
delays and related administrative uncertainties.
 
Foreign equity securities may  be held by an  Underlying Theme Portfolio in  the
form  of ADRs,  ADSs, EDRs, CDRs  or securities convertible  into foreign equity
securities. ADRs,  ADSs, EDRs  and CDRs  may be  listed on  stock exchanges,  or
traded  in the OTC markets in  the United States or Europe,  as the case may be.
ADRs, like other  securities traded  in the United  States, will  be subject  to
negotiated  commission rates. The foreign and domestic debt securities and money
market instruments  in  which  an  Underlying Theme  Portfolio  may  invest  are
generally traded in the OTC markets.
 
An  Underlying Theme  Portfolio does  not have any  obligation to  deal with any
broker/dealer  or  group  of  broker/dealers  in  the  execution  of  securities
transactions. Each Underlying Theme Portfolio contemplates that, consistent with
the  policy of  obtaining the  best net  results, brokerage  transactions may be
conducted through certain  companies that  are members  of Liechtenstein  Global
Trust.  Both Boards have adopted procedures  in conformity with Rule 17e-1 under
the 1940 Act to  ensure that all brokerage  commissions paid to such  affiliates
are  reasonable  and  fair  in the  context  of  the market  in  which  they are
operating. Any such transactions will be effected and related compensation  paid
only in accordance with applicable SEC regulations.
 
PORTFOLIO TRADING AND TURNOVER
The  Fund's portfolio turnover rate  is expected to be  low, since the Fund will
only periodically rebalance its portfolio. The Fund's annual portfolio  turnover
rate is not expected to exceed 20% annually.
 
The portfolio turnover rates of the Underlying Theme Portfolios have ranged from
37%  to 169% during  their most recent  fiscal years. There  can be no assurance
that the portfolio turnover rates of the Underlying Theme Portfolios will remain
within this  range during  subsequent fiscal  years. Higher  portfolio  turnover
rates  may  result in  higher expenses  being incurred  by the  Underlying Theme
Portfolios.

- --------------------------------------------------------------------------------
 
MANAGEMENT SERVICES RELATING TO THE FUND
The  Manager acts as  the manager for the  Fund pursuant to  a contract with the
Trust. The Manager  receives no fees  for providing management  services to  the
Fund.
 
DISTRIBUTION SERVICES RELATING TO THE FUND
   
The  Fund's Class A, Class B and Class C shares are offered continuously through
the Fund's principal underwriter and distributor, GT Global, on a "best efforts"
basis pursuant  to separate  Distribution  Contracts between  the Trust  and  GT
Global.
    
 
   
As  described in the  Prospectus, the Trust has  adopted a separate Distribution
Plan with respect to  the Class A,  Class B and  Class C shares  of the Fund  in
accordance  with Rule 12b-1 under the 1940 Act  (each a "Class A Plan," "Class B
Plan," and "Class C Plan," respectively, and collectively, "Plans"). The rate of
payments by the Fund under the Plans, as described in the Prospectus, may not be
increased without  the  approval  of  the majority  of  the  outstanding  voting
securities of the affected class. All expenses for which GT Global is reimbursed
under  a  Class  A  Plan  will  have  been  incurred  within  one  year  of such
reimbursement.
    
 
In approving the Plans, the Trustees  determined that the adoption of the  Plans
was in the best interests of the shareholders of the Fund. Agreements related to
the  Plans  must also  be approved  by such  vote of  the Trustees,  including a
majority of Trustees who are not  "interested persons" of the Trust (as  defined
in  the 1940 Act) and who have no  direct or indirect financial interests in the
operation of the Plans, or in any agreement related thereto.
 
Each Plan requires  that, at least  quarterly, the Trustees  review the  amounts
expended thereunder and the purposes for which such expenditures were made. Each
Plan  requires that so long as it is  in effect, the selection and nomination of
Trustees who are not "interested persons" of the Trust will be committed to  the
discretion  of the Trustees  who are not  "interested persons" of  the Trust, as
defined in the 1940 Act.
 
As discussed in  the Prospectus, GT  Global collects sales  charges on sales  of
Class A shares of the Fund, retains certain amounts of such charges and reallows
other amounts of such charges to broker/dealers that sell shares.
 
   
GT  Global receives any contingent deferred sales charges ("CDSCs") payable with
respect to redemptions of  Class B shares,  Class C shares  and certain Class  A
shares.
    
 
TRANSFER AGENCY AND ACCOUNTING AGENCY SERVICES
   
The  Transfer  Agent  has  been  retained by  the  Fund  to  perform shareholder
servicing, reporting  and general  transfer agent  functions for  it. For  these
services,  the Transfer Agent  receives an annual maintenance  fee of $17.50 per
account, a new account fee of $4.00 per account, a per transaction fee of  $1.75
for  all transactions other than exchanges and  a per exchange fee of $2.25. The
Transfer Agent is also reimbursed for its out-of-pocket expenses for such  items
as  postage,  forms,  telephone  charges, stationery  and  office  supplies. The
Manager also serves as the Fund's pricing and accounting agent. See  "Additional
Information -- Special Servicing Agreement."

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

- --------------------------------------------------------------------------------
 
PAYMENT AND TERMS OF OFFERING
   
Payment for Class  A, Class B  or Class C  shares of the  Fund purchased  should
accompany  the purchase order, or funds should be wired to the Transfer Agent as
described in  the  Prospectus. Payment  for  Fund  shares, other  than  by  wire
transfer,  must be made by check or money  order drawn on a U.S. bank. Checks or
money orders must be payable in U.S. dollars.
    
 
   
As a condition of  this offering, if an  order to purchase Class  A, Class B  or
Class C shares is canceled due to nonpayment (for example, on account of a check
returned  for "not  sufficient funds"),  the person who  made the  order will be
responsible for any loss incurred by the Underlying Theme Fund by reason of such
cancellation, and if such  purchaser is a shareholder,  the Fund shall have  the
authority  as agent of the shareholder to redeem shares in his or her account at
their then-current net asset value per share to reimburse the Fund for the  loss
incurred.  Investors whose purchase orders have  been canceled due to nonpayment
may be prohibited from placing future orders.
    
 
The Fund  reserves the  right  at any  time to  waive  or increase  the  minimum
requirements applicable to initial or subsequent investments with respect to any
person  or class of persons.  An order to purchase shares  is not binding on the
Fund until it  has been confirmed  in writing  by the Transfer  Agent (or  other
arrangements  made with the Fund, in the  case of orders utilizing wire transfer
of funds, as described above) and payment has been received. To protect existing
shareholders, the Fund reserves the right to reject any offer for a purchase  of
shares by any individual.
 
SALES OUTSIDE THE UNITED STATES
Sales  of Fund shares made through brokers  outside the United States will be at
net asset value plus a sales commission,  if any, established by that broker  or
by  local law. Such  a commission, if  any, may be  more or less  than the sales
charges listed in the sales charge table included in the Prospectus.
 
   
AUTOMATIC INVESTMENT PLAN -- CLASS A, CLASS B AND CLASS C SHARES
    
   
To establish  participation in  the Fund's  Automatic Investment  Plan  ("AIP"),
investors  or their broker/dealers should specify  whether investment will be in
Class A, Class B or  Class C shares and should  send the following documents  to
the  Transfer Agent: (1) an AIP Application;  (2) a Bank Authorization Form; and
(3) a voided personal check from the pertinent bank account. The necessary forms
are provided at  the back of  the Prospectus. Provided  that an investor's  bank
accepts  the Bank  Authorization Form, investment  amounts will be  drawn on the
designated dates (monthly on the 25th day or beginning quarterly on the 25th day
of the  month  the  investor  first  selects) in  order  to  purchase  full  and
fractional  shares of the Fund  at the public offering  price determined on that
day. In the  event that the  25th day falls  on a Saturday,  Sunday or  holiday,
shares  will be purchased  on the next  business day. If  an investor's check is
returned because of insufficient funds or a stop payment order or if the account
is closed, the AIP may be discontinued, and any share purchase made upon deposit
of such check may be canceled.  Furthermore, the shareholder will be liable  for
any loss incurred by the
    
 
                  Statement of Additional Information Page 31
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Fund  by reason of such  cancellation. Investors should allow  one month for the
establishment of an AIP. An AIP may  be terminated by the Transfer Agent or  the
Fund  upon thirty days' written notice or by the participant at any time without
penalty, upon written notice to the Fund or the Transfer Agent.
 
LETTER OF INTENT -- CLASS A SHARES
The Letter  of  Intent ("LOI")  is  not a  binding  obligation to  purchase  the
indicated amount. During such time as Class A shares are held in escrow under an
LOI to ensure payment of applicable sales charges if the indicated amount is not
met,  all dividends  and capital gain  distributions on escrowed  shares will be
reinvested in additional Class  A shares or  paid in cash,  as specified by  the
shareholder.  If the intended  investment is not  completed within the specified
thirteen-month period,  the purchaser  must remit  to GT  Global the  difference
between  the sales charge  actually paid and  the sales charge  which would have
been applicable if the total Class A  purchases had been made at a single  time.
If  this  amount is  not  paid to  GT Global  within  twenty days  after written
request, the appropriate  number of  escrowed shares  will be  redeemed and  the
proceeds paid to GT Global.
 
A  registered investment adviser,  trust company or  trust department seeking to
execute an LOI  as a single  purchaser with  respect to accounts  over which  it
exercises  investment discretion is required to  provide the Transfer Agent with
information establishing that it has discretionary authority with respect to the
money invested (e.g., by providing a  copy of the pertinent investment  advisory
agreement).  Class A shares purchased in this manner must be registered with the
Transfer Agent  so that  only the  investment adviser,  trust company  or  trust
department,  and  not the  beneficial  owner, will  be  able to  place purchase,
redemption and exchange orders.
 
   
CONVERSION OF CLASS B SHARES
    
   
Class B shares of the Fund automatically  will convert to Class A shares,  based
on  the relative net asset values per share of the two classes, eight years from
the end of the calendar month in  which the shareholder's order to purchase  was
accepted.  For  the  purpose  of calculating  the  holding  period  required for
conversion of Class B shares, the  date the shareholder's order to purchase  was
accepted  shall mean (i) the  date on which such Class  B shares were issued, or
(ii) for Class B shares obtained through an exchange, or a series of  exchanges,
the  date on  which the  original Class  B shares  were issued.  For purposes of
conversion to Class  A, Class  B shares  purchased through  the reinvestment  of
dividends and other distributions paid in respect of Class B shares will be held
in  a separate sub-account.  Each time any  Class B shares  in the shareholder's
regular account (other than those in the sub-account) convert to Class A, a  pro
rata portion of the Class B shares in the sub-account will also convert to Class
A.  The portion will be  determined by the ratio  that the shareholder's Class B
shares converting to Class A bears to the shareholder's total Class B shares not
acquired through dividends and other distributions.
    
 
   
The availability  of  the  conversion  feature  is  subject  to  the  continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions   paid  on  Class  A  and  Class  B  shares  will  not  result  in
"preferential dividends" under the Internal  Revenue Code and the conversion  of
shares  does not constitute a taxable event. If the conversion feature ceased to
be available, the Class B shares would not be converted and would continue to be
subject to the higher ongoing expenses of the Class B shares beyond eight  years
from  the  date of  purchase. The  Manager has  no reason  to believe  that this
condition for the availability of the conversion feature will not be met.
    
 
   
INDIVIDUAL RETIREMENT ACCOUNTS ("IRAS") AND OTHER TAX-DEFERRED PLANS
    
   
Class A,  Class  B or  Class  C shares  of  the Fund  may  be purchased  as  the
underlying  investment for an  IRA meeting the  requirements of sections 408(a),
408A or 530 of the  Internal Revenue Code of 1986,  as amended (the "Code"),  as
well  as  for  qualified retirement  plans  described  in Code  Section  401 and
custodial accounts complying with Code Section 403(b)(7).
    
 
   
IRAS: If you have earned income from employment (including self-employment), you
can contribute each year to an IRA up  to the lesser of (1) $2,000 for  yourself
or  $4,000  for  you and  your  spouse,  regardless of  whether  your  spouse is
employed, or (2) 100% of compensation. Some  individuals may be able to take  an
income tax deduction for the contribution. Regular contributions may not be made
for  the year  you become 70  1/2 or  thereafter. Unless your  and your spouse's
earnings exceed  a certain  level, you  also may  establish an  "education  IRA"
and/or  a "Roth  IRA." Although  contributions to  these new  types of  IRAs are
nondeductible,  withdrawals   from  them   will   be  tax-free   under   certain
circumstances.  Please  consult  your  tax  advisor  for  more  information. IRA
applications are available from brokers or GT Global.
    
 
   
ROLLOVER IRAS: Individuals who  receive distributions from qualified  retirement
plans  (other than  required distributions) and  who wish to  keep their savings
growing tax-deferred  can  roll  over  (or make  a  direct  transfer  of)  their
distribution  to a  Rollover IRA. These  accounts can also  receive rollovers or
transfers from an existing IRA. If an "eligible rollover
    
 
                  Statement of Additional Information Page 32
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
   
distribution"  from  a  qualified  employer-sponsored  retirement  plan  is  not
directly  rolled over to an IRA (or certain qualified plans), withholding at the
rate of 20%  will be required  for federal income  tax purposes. A  distribution
from a qualified plan that is not an "eligible rollover distribution," including
a distribution that is one of a series of substantially equal periodic payments,
generally  is subject to regular wage withholding  or withholding at the rate of
10% (depending on the type and amount of the distribution), unless you elect not
to have  any  withholding  apply.  Please consult  your  tax  advisor  for  more
information.
    
 
   
SEP-IRAS:  Simplified  employee  pension plans  ("SEPs"  or  "SEP-IRAs") provide
self-employed individuals (and any eligible employees) with benefits similar  to
Keogh  plans (i.e., self-employed  individual retirement plans)  or Code Section
401(k) plans, but with fewer administrative requirements and therefore 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.
    
 
EXCHANGES
   
Shares  of the Fund may be exchanged for shares of other GT Global Mutual Funds,
based on  their respective  net asset  values without  imposition of  any  sales
charges  provided that the registration remains identical. Class A shares of the
Fund may be exchanged only for Class  A shares of other GT Global Mutual  Funds.
Class  B shares of the Fund may be exchanged only for Class B shares of other GT
Global Mutual Funds. Class C shares of the Fund may be exchanged only for  Class
C shares of other GT Global Mutual Funds. Exchange privileges for Class C shares
will not be available until other GT Global Mutual Funds commence offering Class
C  shares, which is  expected to occur on  or about March  1, 1998. The exchange
privilege is not an option  or right to purchase  shares but is permitted  under
the current policies of the respective GT Global Mutual Funds. The privilege may
be discontinued or changed at any time by any of the funds upon sixty days prior
written  notice to the shareholders of such fund and is available only in states
where the exchange  may be made  legally. Before purchasing  shares through  the
exercise  of the exchange privilege, a shareholder should obtain and read a copy
of the prospectus of the fund to be purchased and should consider the investment
objective(s) of the fund.
    
 
TELEPHONE REDEMPTIONS
A corporation or  partnership wishing to  utilize telephone redemption  services
must  submit a "Corporate Resolution" or "Certificate of Partnership" indicating
the names, titles and the required number of signatures of persons authorized to
act on  its  behalf.  The  certificate  must be  signed  by  a  duly  authorized
officer(s),  and,  in the  case of  a  corporation, the  corporate seal  must be
affixed. All shareholders may request that redemption proceeds be transmitted by
bank wire upon request directly to the shareholder's predesignated account at  a
domestic  bank or savings institution if the proceeds are at least $1,000. Costs
in connection with the administration  of this service, including wire  charges,
currently  are borne by the Fund. Proceeds of less than $1,000 will be mailed to
the shareholder's registered address of record. The Fund and the Transfer  Agent
reserve  the right to refuse any  telephone instructions and may discontinue the
aforementioned redemption options upon thirty days' written notice.
 
SYSTEMATIC WITHDRAWAL PLAN
   
Shareholders owning Class A, Class B or Class C shares of the Fund with a  value
of  $10,000 or more may establish a Systematic Withdrawal Plan ("SWP"). Under an
SWP, a shareholder will receive monthly or quarterly payments, in amounts of not
less than $100 per  payment, through the automatic  redemption of the  necessary
number  of shares on the designated dates  (monthly on the 25th day or quarterly
on the 25th day of January, April, July and October). In the event that the 25th
day falls on a Saturday,  Sunday or holiday, the  redemption will take place  on
the prior business day. Certificates, if any, for the shares being redeemed must
be  held by the  Transfer Agent. Checks  will be made  payable to the designated
recipient and  mailed within  seven days.  If the  recipient is  other than  the
registered  shareholder, the signature of each shareholder must be guaranteed on
the  SWP  application  (see  "How  to  Redeem  Shares"  in  the  Prospectus).  A
corporation  (or partnership)  must also  submit a  "Corporation Resolution" (or
"Certificate of Partnership") indicating the

names, titles,  and signatures  of  the individuals  authorized  to act  on  its
behalf,  and the SWP application must be  signed by a duly authorized officer(s)
and the corporate seal affixed.
 
With respect to a SWP, the maximum  annual SWP withdrawal is 12% of the  initial
account  value.  Withdrawals  in excess  of  12%  of the  initial  account value
annually may result  in assessment of  a contingent deferred  sales charge.  See
"How to Invest" in the Prospectus.
 
Shareholders should be aware that such systematic withdrawals may deplete or use
up  entirely  the  initial  investment  and  result  in  realized  long-term  or
short-term capital gains or losses. The SWP may be terminated at any time by the
Transfer Agent or the Fund upon thirty days' written notice or by a  shareholder
upon  written notice to the Fund or its Transfer Agent. Applications and further
details regarding  establishment of  an SWP  are  provided at  the back  of  the
Prospectus.
 
SUSPENSION OF REDEMPTION PRIVILEGES
The  Fund may suspend redemption privileges or  postpone the date of payment for
more than seven days after a redemption order is received during any period  (1)
when  the NYSE is closed  other than customary weekend  and holiday closings, or
trading on the NYSE is restricted as directed by the SEC, (2) when an  emergency
exists,  as defined by the SEC, which  would prohibit the Fund or the Underlying
Theme Portfolios from  disposing of  portfolio securities  owned by  them or  in
fairly  determining the value of  their assets, or (3)  as the SEC may otherwise
permit.
 
REDEMPTIONS IN KIND
It is  possible that  conditions may  arise in  the future  that would,  in  the
opinion  of the Trust's Board  of Trustees, make it  undesirable for the Fund to
pay for all redemptions in cash. In such cases, the Board may authorize  payment
to  be made  in portfolio  securities or other  property of  the Fund, so-called
"redemptions in kind." Payment  of redemptions in kind  will be made in  readily
marketable  securities.  Such  securities  would be  valued  at  the  same value
assigned to  them in  computing  the net  asset  value per  share.  Shareholders
receiving  such  securities  would incur  brokerage  costs in  selling  any such
securities so received. However, despite the foregoing, the Trust has filed with
the SEC an election pursuant to Rule  18f-1 under the 1940 Act. This means  that
the Fund will pay in cash all requests for redemption made by any shareholder of
record, limited in amount with respect to each shareholder during any ninety-day
period to the lesser of $250,000 or 1% of the net asset value of the Fund at the
beginning  of such  period. This  election will be  irrevocable so  long as Rule
18f-1 remains in effect,  unless the SEC by  order upon application permits  the
withdrawal of such election.

                                     TAXES
 
- --------------------------------------------------------------------------------
 
TAXATION OF THE FUND
   
To  continue to qualify for treatment  as a regulated investment company ("RIC")
under the Code, the  Fund must distribute to  its shareholders for each  taxable
year at least 90% of its investment company taxable income (consisting generally
of  net  investment  income  and  net  short-term  capital  gain) ("Distribution
Requirement") and must meet several additional requirements. These  requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each  taxable year from dividends, interest, payments with respect to securities
loans and  gains from  the sale  or other  disposition of  securities, or  other
income  derived with respect to its business  of investing in securities; (2) at
the close of each quarter of the Fund's taxable year, at least 50% of the  value
of  its total assets must be represented by cash and cash items, U.S. government
securities, securities of other RICs (including the Underlying Theme Funds)  and
other  securities, with  these other securities  limited, in respect  of any one
issuer, to an amount that  does not exceed 5% of  the value of the Fund's  total
assets  and that does  not represent more  than 10% of  the issuer's outstanding
voting securities; and (3) at  the close of each  quarter of the Fund's  taxable
year,  not more than  25% of the  value of its  total assets may  be invested in
securities (other than  U.S. government  securities or the  securities of  other
RICs, including the Underlying Theme Funds) of any one issuer.
    
 
   
The  Fund will invest its  assets in shares of  the Underlying Theme Funds, cash
and money market  instruments. Accordingly,  the Fund's income  will consist  of
distributions  from  the Underlying  Theme Funds,  net  gains realized  from the
disposition of Underlying Theme Fund shares and interest. If an Underlying Theme
Fund qualifies for treatment as a RIC under the Code -- each has done so for its
past taxable years and intends to continue  to do so for its current and  future
taxable years -- (1) dividends paid to the Fund from the Underlying Theme Fund's
investment  company taxable  income (which  may include  net gains  from certain
foreign currency transactions) will be taxable to the Fund as ordinary income to
the extent  of  the  Underlying  Theme  Fund's  earnings  and  profits  and  (2)
distributions paid to the Fund from the Underlying Theme Fund's net capital gain
(the  excess of  net long-term capital  gain over net  short-term capital loss),
when designated as such, will be taxable to the Fund as long-term capital gains,
regardless of how long the Fund has held the Underlying Theme Fund's shares.
    
 
   
If shares of an  Underlying Theme Fund  are purchased within  30 days before  or
after  redeeming other shares of that Underlying Theme Fund (whether pursuant to
a rebalancing of the Fund's portfolio or otherwise) at a loss, all or a part  of
the  loss will not be deductible by the Fund and instead will increase its basis
for the newly purchased shares.
    
 
Although an Underlying Theme Fund will be eligible to elect to "pass-through" to
its shareholders (including the Fund) the benefit of the foreign tax credit with
respect to any foreign and  U.S. possessions income taxes  it pays if more  than
50%  in the value of its total assets  at the close of any taxable year consists
of securities of foreign  corporations, the Fund will  not qualify to pass  that
benefit  through to  its shareholders because  of its inability  to satisfy that
asset test.
 
The Fund will be subject to a nondeductible 4% excise tax to the extent it fails
to distribute by the end of any calendar year substantially all of its  ordinary
income  for that year and capital gain net income for the one-year period ending
on October 31 of that year, plus certain other amounts.
 
TAXATION OF THE FUND'S SHAREHOLDERS
   
Dividends  and  other  distributions  declared  by  the  Fund,  and  payable  to
shareholders  of record as  of a date,  in October, November  or December of any
year will  be  deemed  to have  been  paid  by  the Fund  and  received  by  the
shareholders  on December 31 of  that year if the  distributions are paid by the
Fund during  the following  January. Accordingly,  those distributions  will  be
taxed to shareholders for the year in which that December 31 falls.
    
 
   
A  portion of  the dividends from  the Fund's investment  company taxable income
(whether paid in cash  or reinvested in additional  shares) may be eligible  for
the  dividends-received deduction allowed to  corporations. The eligible portion
may not exceed the total of the Fund's share of the aggregate dividends received
by each  Underlying  Theme  Fund  from  U.S.  corporations.  However,  dividends
received  by  a  corporate  shareholder  and  deducted  by  it  pursuant  to the
dividends-received deduction  may  be  subject  indirectly  to  the  alternative
minimum tax.
    
 
                  Statement of Additional Information Page 35
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
If  Fund shares are sold at a loss after  being held for six months or less, the
loss will be treated  as long-term, instead of  short-term, capital loss to  the
extent  of any  capital gain distributions  received on  those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or other distribution, the shareholder will pay full price  for
the shares and receive some portion of the price back as a taxable distribution.
 
Dividends  paid by the Fund to a shareholder  who, as to the United States, is a
nonresident alien individual, nonresident alien fiduciary of a trust or  estate,
foreign  corporation  or foreign  partnership ("foreign  shareholder") generally
will be subject to U.S. withholding tax (at a rate of 30% or lower treaty rate).
Withholding will  not  apply  if a  dividend  paid  by the  Fund  to  a  foreign
shareholder  is  "effectively connected  with  the conduct  of  a U.S.  trade or
business," in which case the  reporting and withholding requirements  applicable
to  domestic shareholders will apply. A distribution  of net capital gain by the
Fund to a foreign shareholder generally  will be subject to U.S. federal  income
tax  (at the rates applicable  to domestic persons) only  if the distribution is
"effectively connected" or the foreign  shareholder is treated as a  nonresident
alien individual for federal income tax purposes.
 
The  foregoing  is a  general  and abbreviated  summary  of certain  federal tax
considerations affecting the Fund and  its shareholders. Investors are urged  to
consult their own tax advisers for more detailed information and for information
regarding  any  foreign,  state  and  local  taxes  applicable  to distributions
received from the Fund.

                             ADDITIONAL INFORMATION
 
- --------------------------------------------------------------------------------
 
SPECIAL SERVICING AGREEMENT
Subject to the receipt of an  exemptive application pending with the  Securities
and  Exchange Commission  and a private  letter ruling request  pending with the
Internal  Revenue  Service,   a  Special  Servicing   Agreement  (the   "Service
Agreement")  will be entered into among the Manager, the Underlying Theme Funds,
GT Global Investor  Services, Inc., and  the Trust. The  Service Agreement  will
provide  that, if the officers of any Underlying Theme Fund, at the direction of
the Board of Directors,  determine that the aggregate  expenses of the Fund  are
less  than the estimated savings to the Underlying Theme Fund from the operation
of the Fund, the Underlying Theme Fund will bear those expenses in proportion to
the average daily value  of its shares  owned by the Fund  and/or the number  of
shareholder  accounts  at the  Fund.  No Underlying  Theme  Fund will  bear such
expenses in excess of the estimated savings to it. Such savings are expected  to
result  primarily from the elimination of numerous separate shareholder accounts
which are or would have been invested directly in the Underlying Theme Funds and
the resulting  reduction in  shareholder servicing  costs. In  this regard,  the
shareholder  servicing  costs to  any Underlying  Theme  Fund for  servicing one
account registered to  the Trust would  be significantly less  than the cost  to
that same Underlying Theme Fund of servicing the same pool of assets contributed
in  the typical fashion by a large group of individual shareholders owning small
accounts in  each  Underlying  Theme  Fund. In  the  event  that  the  aggregate
financial  benefits to the Underlying Theme Funds do not exceed the costs of the
Fund, the Manager will pay, on behalf of the Fund, that portion of costs, as set
forth herein, determined to be greater than the benefits.
 
   
Rule 12b-1 distribution and service fees will not be paid in accordance with the
Service Agreement. In addition, certain non-recurring and extraordinary expenses
will not be paid  in accordance with the  Service Agreement including: the  fees
and  costs of  actions, suits  or proceedings  and any  penalties or  damages in
connection therewith, to which the Trust and/or the Fund may incur directly,  or
may  incur as a result of its legal obligation to provide indemnification to its
officers,  trustees  and  agents;  the  fees  and  costs  of  any   governmental
investigation  and  any  fines or  penalties  in connection  therewith;  and any
federal, state or local tax, or related interest penalties or additions to  tax,
incurred,  for example, as a result of  the Trust's failure to distribute all of
its earnings, failure to  qualify as a  RIC under subchapter  M of the  Internal
Revenue  Code,  or failure  to timely  file  any required  tax returns  or other
filings.

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

                               INVESTMENT RESULTS
 
- --------------------------------------------------------------------------------
 
STANDARDIZED RETURNS
   
The  Fund's "Standardized Returns," as referred to in the Prospectus (see "Other
Information --  Performance  Information"  in  the  Prospectus),  is  calculated
separately  for Class  A, Class B  and Class C  shares of the  Fund, as follows:
Standardized Return (average annual total return ("T")) is computed by using the
ending redeeming value ("ERV")  of a hypothetical  initial investment of  $1,000
("P")  over  a period  of  years ("n")  according  to the  following  formula as
required by the SEC: P(1+T) =  ERV. The following assumptions will be  reflected
in  computations made in accordance  with this formula: (1)  for Class A shares,
deduction of  the  maximum  sales  charge  of  4.75%  from  the  $1,000  initial
investment;  (2)  for Class  B shares,  deduction  of the  applicable contingent
deferred sales charge imposed  on a redemption  of Class B  shares held for  the
period; (3) reinvestment of dividends and other distributions at net asset value
on  the reinvestment date determined by the Trust's Board of Trustees; and (4) a
complete redemption at the end of any period illustrated.

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
NON-STANDARDIZED RETURNS
   
In  addition   to  Standardized   Returns,  the   Fund  also   may  include   in
advertisements,  sales  literature and  shareholder  reports other  total return
performance  data  ("Non-Standardized   Return").  Non-Standardized  Return   is
calculated  separately for Class A,  Class B and Class C  shares of the Fund and
may be  calculated according  to  several different  formulas.  Non-Standardized
Returns  may  be  quoted  for  the same  or  different  time  periods  for which
Standardized Returns are quoted.  Non-Standardized Returns may  or may not  take
sales  charges  into account;  performance  data calculated  without  taking the
effect of sales  charges into  account will be  higher than  data including  the
effect of such charges.
    
 
Average  annual Non-Standardized  Return ("T") is  computed by  using the ending
redeeming value ("ERV")  of a  hypothetical initial investment  of $1,000  ("P")
over  a period of years ("n") according  to the following formula as required by
the  SEC:  P(1+T)  =  ERV.  The  following  assumptions  will  be  reflected  in
computations  made in  accordance with this  formula: (1) no  deduction of sales
charges; (2)  reinvestment of  dividends and  other distributions  at net  asset
value  on the  reinvestment date  determined by  the Board;  and (3)  a complete
redemption at the end of any period illustrated.
 
The Fund's investment results will vary from time to time depending upon  market
conditions,  the composition of each Underlying Theme Portfolio's portfolio, and
operating expenses of the Fund,  so that current or  past yield or total  return
should  not be considered representative  of what an investment  in the Fund may
earn in any future period. These factors and possible differences in the methods
used in calculating investment results  should be considered when comparing  the
Fund's  investment results with  those published for  other investment companies
and other  investment vehicles.  The Fund's  results also  should be  considered
relative  to  the  risks associated  with  the Fund's  investment  objective and
policies.
 
IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKET
The Fund and GT Global may from time to time in advertisements, sales literature
and reports furnished to  present or prospective  shareholders compare the  Fund
with the following, among others:
 
        (1)  The Consumer Price Index ("CPI"), which is a measure of the average
    change in prices over time  in a fixed market  basket of goods and  services
    (e.g.,  food, clothing,  shelter, fuels,  transportation fares,  charges for
    doctors' and dentists' services, prescription medicines, and other goods and
    services that people  buy for  day-to-day living). There  is inflation  risk
    which  does not affect a security's value but its purchasing power, i.e. the
    risk of changing price levels in the economy that affects security prices or
    the price of goods and services.
 
        (2) Data  and  mutual fund  rankings  published or  prepared  by  Lipper
    Analytical  Data  Services,  Inc.  ("Lipper"),  CDA/Wiesenberger  Investment
    Companies Service  ("CDA/Wiesenberger"), Morningstar,  Inc., Micropal,  Inc.
    and/or  other companies  that rank  and/or compare  mutual funds  by overall
    performance, investment  objectives,  assets,  expense  levels,  periods  of
    existence  and/or other factors. In this regard  the Fund may be compared to
    its "peer group" as defined by Lipper, CDA/Wiesenberger, Morningstar  and/or
    other  firms, as applicable, or to specific  funds or groups of funds within
    or outside of such peer group. Lipper generally ranks funds on the basis  of
    total  return,  assuming reinvestment  of distributions,  but does  not take
    sales charges or redemption fees into consideration, and is prepared without
    regard to tax  consequences. In addition  to the mutual  fund rankings,  the
    Fund's  performance  may  be  compared to  mutual  fund  performance indices
    prepared by Lipper. Morningstar  is a mutual fund  rating service that  also
    rates  mutual funds on  the basis of  risk-adjusted performance. Morningstar
    ratings are calculated from a fund's three, five and ten year average annual
    returns with appropriate  fee adjustments  and a risk  factor that  reflects
    fund  performance  relative to  the three-month  U.S. Treasury  bill monthly
    returns. Ten percent  of the funds  in an investment  category receive  five
    stars  and 22.5% receive four stars. The  ratings are subject to change each
    month.
 
        (3) Bear  Stearns  Foreign Bond  Index,  which provides  simple  average
    returns for individual countries and gross national product ("GNP") weighted
    index,  beginning in 1975. The  returns are broken down  by local market and
    currency.
 
   
        (4) Ibbotson  Associates  International  Bond Index,  which  provides  a
    detailed breakdown of local market and currency returns since 1960.
    
 
        (5) Standard & Poor's 500 Composite Stock Price Index, which is a widely
    recognized  index  composed of  the  capitalization-weighted average  of the
    price of 500 of the largest publicly traded stocks in the United States.

German  Deutschemark,  and  Hong  Kong  Dollar).  A  foreign  currency  that has
strengthened or weakened against the  U.S. dollar will positively or  negatively
affect the reported returns, as the case may be.
 
GT  Global believes that this information may be useful to investors considering
whether and to what extent to  diversify their investments through the  purchase
of mutual funds investing in securities on a global basis. However, this data is
not a representation of the past performance of the Fund, nor is it a prediction
of such performance. The performance of the Fund will differ from the historical
performance  of  relevant  indices. The  performance  of indices  does  not take
expenses into account, while the Fund  incurs expenses in its operations,  which
will reduce performance. Each of these factors will cause the performance of the
Fund to differ from relevant indices.
 
From  time  to  time,  the  Fund  and GT  Global  may  refer  to  the  number of
shareholders in  the Fund  or the  aggregate number  of shareholders  in all  GT
Global  Mutual Funds or the dollar amount  of the Fund's assets under management
or rankings by DALBAR Surveys, Inc. in advertising materials.
 
GT  Global  believes  the  Fund  is  an  appropriate  investment  for  long-term
investment   goals  including  funding  retirement,   paying  for  education  or
purchasing  a  house.  GT  Global  may  provide  information  designed  to  help
individuals  understand  their investment  goals  and explore  various financial
strategies. For example, GT Global may describe general principles of investing,
such as asset allocation, diversification and risk tolerance. The Fund does  not
represent  a complete investment program, and investors should consider the Fund
as appropriate for a portion of  their overall investment portfolio with  regard
to  their  long-term  investment goals.  There  is  no assurance  that  any such
information will lead to achieving these goals or guarantee future results.
 
From time to time,  GT Global may refer  to or advertise the  names of U.S.  and
non-U.S.  companies and their products, although  there can be no assurance that
any GT Global Mutual Fund may own the securities of these companies.
 
Ibbotson Associates of Chicago, Illinois (Ibbotson) provides historical  returns
of  the capital  markets in  the United  States, including  common stocks, small
capitalization stocks, long-term  corporate bonds, intermediate-term  government
bonds,  long-term government bonds,  Treasury bills, the  U.S. rate of inflation
(based on the CPI), and combinations of various capital markets. The performance
of these capital markets are based on the returns of different indices.
 
GT Global Mutual Funds may use the performance of these capital markets in order
to demonstrate  general  risk-versus-reward  investment  scenarios.  Performance
comparisons  may also include the  value of a hypothetical  investment in any of
these capital  markets. The  risks associated  with the  security types  in  any
capital  market  may or  may  not correspond  directly  to those  of  the funds.
Ibbotson calculates total returns in the same method as the funds.
 
The Fund may quote various measures of volatility and benchmark correlation such
as beta, standard  deviation and  R in advertising.  In addition,  the Fund  may
compare  these measures to those of other  funds. Measures of volatility seek to
compare the Fund's historical share price fluctuations or total returns compared
to those  of  a  benchmark.  All measures  of  volatility  and  correlation  are
calculated using averages of historical data.
 
   
The  Fund may  advertise examples of  the effects of  periodic investment plans,
including the principle of dollar cost averaging programs. In such a program, an
investor invests a fixed dollar amount in a fund at periodic intervals,  thereby
purchasing  fewer shares when  prices are high  and more shares  when prices are
low. While such a strategy does not assure  a profit or guard against loss in  a
declining  market, the investor's  average cost per  share can be  lower than if
fixed numbers of shares are purchased at the same intervals. In evaluating  such
a  plan, investors should  consider their ability  to continue purchasing shares
through periods of low price levels.
    
 
   
The Fund may describe in its  sales material and advertisements how an  investor
may  invest in GT Global Mutual Funds  through various retirement plans or other
programs that offer deferral of income taxes on investment earnings and to which
an investor  may make  deductible contributions.  Because of  their  advantages,
these  retirement plans and programs may  produce returns superior to comparable
non-retirement investments. For example, a $10,000 investment earning a  taxable
return of 10% annually would have an after-tax value of $17,976 after ten years,
assuming  tax  was  deducted from  the  return each  year  at a  39.6%  rate. An
equivalent tax-deferred  investment would  have an  after-tax value  of  $19,626
after  ten years, assuming  tax was deducted  at a 39.6%  rate from the deferred
earnings  at  the   end  of  the   ten-year  period.  In   sales  material   and
advertisements,  the  Fund  may  also  discuss  these  plans  and  programs. See
"Information Relating to Sales and Redemptions -- Individual Retirement Accounts
("IRAs") and Other Tax-Deferred Plans."
    
 
   
GT Global may from time to time  in its sales materials and advertising  discuss
the  risks inherent in investing. The major  types of investment risk are market
risk, industry  risk,  credit  risk,  interest rate  risk,  liquidity  risk  and
inflation risk. Risk represents the possibility that you may lose some or all of
your investment over a period of time. A basic tenet of investing is the greater
the potential reward, the greater the risk.

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

time tested investment discipline. With investment professionals in nine offices
worldwide, we witness world events and economic developments firsthand.
 
The  key to achieving  consistent results is  following a disciplined investment
process. Our  approach  to  asset  allocation takes  advantage  of  GT  Global's
worldwide   presence  and  global  perspective.  Our  "macroeconomic"  worldview
determines our overall strategy of regional, country and sector allocations. Our
bottom up  process  of security  selection  combines fundamental  research  with
quantitative analysis through our proprietary models.
 
Built  in  checks and  balances strengthen  the process,  enhancing professional
experience and judgment with an  objective assessment of risk. Ultimately,  each
security  we select has passed  a ranking system that  helps our portfolio teams
determine when to buy and when to sell.
 
   
GT Global describes the major stages  of economic development as revolving in  a
"virtuous  cycle." From time  to time, each  Fund and GT  Global may discuss the
virtuous cycle  in its  sales literature  and advertising.  This cycle  operates
worldwide,   forcing  companies   to  become  increasingly   competitive  in  an
ever-expanding global  marketplace.  GT  Global  has  identified  the  following
sequential stages within the virtuous cycle:
    
 
   
FALLING  BORDERS  AND  TRADE  BARRIERS:  Barriers  between  countries  diminish,
increasing the potential for world trade and promoting global competition.
    
 
   
CAPITAL FLOWS  FROM DEVELOPED  MARKETS TO  EMERGING MARKETS:  As barriers  fall,
restrictions  on the free movement of capital in  and out of a country are often
reduced or removed. The flow of money from developed to developing markets gains
momentum.
    
 
   
INDUSTRIALIZATION OF EMERGING MARKETS: With capital flowing across borders, many
developing nations are able to quickly begin their process of industrialization.
    
 
   
INCREASED DEMAND FOR  GLOBAL CONSUMER  PRODUCTS: As people  in emerging  markets
experience  rising standards of living  due to increased industrialization, they
demand more consumer products which can help spur global trade flows.
    
 
   
GT Global believes that  we increasingly live in  a world without boundaries  in
terms  of trade, competition and  investment opportunities. Therefore, GT Global
believes it's becoming more relevant to look at investing in terms of industrial
groupings, or themes,  as an alternative  to the traditional,  primary focus  on
regions. GT Global believes such themes make movement possible between stages in
the virtuous cycle of economic progress.
    
 
   
GENERAL INFORMATION ABOUT THE UNDERLYING THEME PORTFOLIOS
    
   
Each  Underlying Theme Portfolio  may invest worldwide  across industries within
the Portfolio's area of concentration without national or regional restrictions.
The ability of each Underlying Theme Portfolio to invest worldwide may allow the
portfolio managers to select industries in different economic cycles and varying
stages of development, though  there is no assurance  that the managers will  be
successful in this selection.
    
 
   
Each  Underlying Theme Portfolio's area of concentration reflects the underlying
theme of  the Portfolio.  GT  Global believes  that  there are  certain  social,
political  and economic trends that may benefit one or more industries within an
Underlying Theme  Portfolio's area  of  concentration. Of  course, there  is  no
assurance that any of the Funds will benefit as a result.

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

DEREGULATION IN THE UNITED STATES
    
   
The United States  has been  the bellwether  for deregulation  of the  telephone
industry.  The  divestiture  of  the Bell  System  from  American  Telephone and
Telegraph has  produced competing  companies  in the  United States.  Such  U.S.
market-driven  competition has,  for example, led  to lower  costs for consumers
which in turn led to greater consumer usage and to higher industrywide revenues.
The Manager expects this scenario to  continue to benefit such companies in  the
U.S.  and  similarly  to  be  realized  by  the  established  telecommunications
companies in established economies, although no  assurances can be made in  this
regard.

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

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

To the Shareholders of
GT Global New Dimension Fund and
Board of Trustees of GT Global Series Trust:
 
   
We have audited the accompanying statement of assets and liabilities of GT
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.
Those standards require that we plan and perform the audit to obtain reasonable
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.

                            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."

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 within
the stated settlement period. An Underlying Theme Portfolio will not have the
right to vote equity securities while they are being lent, but it may call in a
loan in anticipation of any important vote. Loans will only be made to firms
deemed by the Manager to be of good standing and will not be made unless, in the
judgment of the Manager, the consideration to be earned from such loans would
justify the risk. The risks in lending 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.

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The use by the Underlying Theme Portfolios of options, futures contracts and
forward currency contracts ("Forward Contracts") involves special considerations
and risks, as described below. Risks pertaining to particular instruments are
described in the sections that follow.
 
        (1) Successful use of most of these instruments depends upon the
    Manager's ability to predict movements of the overall securities and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Manager is experienced in the
    use of these instruments, there can be no assurance that any particular
    strategy adopted will succeed.
 
        (2) There might be imperfect correlation, or even no correlation,
    between price movements of an instrument and price movements of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge increased by less than the decline in value of the hedged
    investment, the hedge would not be fully successful. Such a lack of
    correlation might occur due to factors unrelated to the value of the
    investments being hedged, such as speculative or other pressures on the
    markets in which the hedging instrument is traded. The effectiveness of
    hedges using hedging instruments on indices will depend on the degree of
    correlation between price movements in the index and price movements in the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or partially offsetting the negative effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by offsetting the positive effect of favorable price
    movements in the hedged investments. For example, if an Underlying Theme
    Portfolio entered into a short hedge because the Manager projected a decline
    in the price of a security in the Underlying Theme Portfolio's portfolio,
    and the price of that security increased instead, the gain from that
    increase might be wholly or partially offset by a decline in the price of
    the hedging instrument. Moreover, if
 
                   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.
 
                   Statement of Additional Information Page 7
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
Each Underlying Theme Portfolio will pay transaction costs in connection with
the writing of options and in entering into closing purchase contracts.
Transaction costs relating to options activity are normally higher than those
applicable to purchases and sales of portfolio securities.
 
The exercise price of the options may be below, equal to or above the current
market values of the underlying securities, indices or currencies at the time
the options are written. From time to time, an Underlying Theme Portfolio may
purchase an underlying security or currency for delivery in accordance with the
exercise of an option, rather than delivering such security or currency from its
portfolio. In such cases, additional costs will be incurred.
 
An Underlying Theme Portfolio will realize a profit or loss from a closing
purchase transaction if the cost of the transaction is less or more,
respectively, than the premium received from writing the option. Because
increases in the market price of a call option generally will reflect increases
in the market price of the underlying security or currency, any loss resulting
from the repurchase of a call option is likely to be offset in whole or in part
by appreciation of the underlying security or currency owned by an Underlying
Theme Portfolio.
 
WRITING PUT OPTIONS
Each Underlying Theme Portfolio may write put options on securities, indices and
currencies. A put option gives the purchaser of the option the right to sell,
and the writer (seller) the obligation to buy, the underlying security or
currency at the exercise price at any time until (American style) or on
(European style) the expiration date. The operation of put options in other
respects, including their related risks and rewards, is substantially identical
to that of call options.
 
An Underlying Theme Portfolio generally would write put options in circumstances
where the Manager wishes to purchase the underlying security or currency for the
Underlying Theme Portfolio's holdings at a price lower than the current market
price of the security or currency. In such event, an Underlying Theme Portfolio
would write a put option at an exercise price that, reduced by the premium
received on the option, reflects the lower price it is willing to pay. Since the
Underlying Theme Portfolio would also receive interest on debt securities or
currencies maintained to cover the exercise price of the option, this technique
could be used to enhance current return during periods of market uncertainty.
The risk in such a transaction would be that the market price of the underlying
security or currency would decline below the exercise price less the premium
received.
 
Writing put options can serve as a limited long hedge because increases in the
value of the hedged investment would be offset to the extent of the premium
received for writing the option. However, if the security or currency
depreciates to a price lower than the exercise price of the put option, it can
be expected that the put option will be exercised and an Underlying Theme
Portfolio will be obligated to purchase the security or currency at greater than
its market value.
 
PURCHASING PUT OPTIONS
Each Underlying Theme Portfolio may purchase put options on securities, indices
and currencies. As the holder of a put option, an Underlying Theme Portfolio
would have the right to sell the underlying security or currency at the exercise
price at any time until (American style) or on (European style) the expiration
date. An Underlying Theme Portfolio may enter into closing sale transactions
with respect to such options, exercise such option or permit such option to
expire.
 
Each Underlying Theme Portfolio may purchase a put option on an underlying
security or currency ("protective put") owned by the Underlying Theme Portfolio
in order to protect against an anticipated decline in the value of the security
or currency. Such hedge protection is provided only during the life of the put
option when the Underlying Theme Portfolio, as the holder of the put option, is
able to sell the underlying security or currency at the put exercise price
regardless of any decline in the underlying security's market price or
currency's exchange value. 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 of the Securities and Exchange Commission ("SEC") considers purchased
OTC options to be illiquid securities. An Underlying Theme Portfolio may also
sell OTC options and, in connection therewith, segregate assets or cover its
    
 
                   Statement of Additional Information Page 9
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
obligations with respect to OTC options written by it. The assets used as cover
for OTC options written by an Underlying Theme Portfolio will be considered
illiquid unless the OTC options are sold to qualified dealers who agree that the
Underlying Theme Portfolio may repurchase any OTC option it writes at a maximum
price to be calculated by a formula set forth in the option agreement. The cover
for an OTC option written subject to this procedure would be considered illiquid
only to the extent that the maximum repurchase price under the formula exceeds
the intrinsic value of the option.
 
An Underlying Theme Portfolio's ability to establish and close out positions in
exchange-listed options depends on the existence of a liquid market. Each
Underlying Theme Portfolio intends to purchase or write only those
exchange-traded options for which there appears to be a liquid secondary market.
However, there can be no assurance that such a market will exist at any
particular time. Closing transactions can be made for OTC options only by
negotiating directly with the contra party or by a transaction in the secondary
market if any such market exists. Although an Underlying Theme Portfolio will
enter into OTC options only with contra parties that are expected to be capable
of entering into closing transactions with it, there is no assurance that the
Underlying Theme Portfolio will in fact be able to close out an OTC option
position at a favorable price prior to expiration. In the event of insolvency of
the contra party, the Underlying Theme Portfolio might be unable to close out an
OTC option position at any time prior to its expiration.
 
INDEX OPTIONS
Puts and calls on indices are similar to puts and calls on securities or futures
contracts except that all settlements are in cash and gain or loss depends on
changes in the index in question (and thus on price movements in the securities
market or a particular market sector generally) rather than on price movements
in individual securities or futures contracts. When an Underlying Theme
Portfolio writes a call on an index, it receives a premium and agrees that,
prior to the expiration date, the purchaser of the call, upon exercise of the
call, will receive from the Underlying Theme Portfolio an amount of cash if the
closing level of the index upon which the call is based is greater than the
exercise price of the call. The amount of cash is equal to the difference
between the closing price of the index and the exercise price of the call times
a specified multiple (the "multiplier"), which determines the total dollar value
for each point of such difference. When an Underlying Theme Portfolio buys a
call on an index, it pays a premium and has the same rights as to such call as
are indicated above. When an Underlying Theme Portfolio buys a put on an index,
it pays a premium and has the right, prior to the expiration date, to require
the seller of the put, upon the Underlying Theme Portfolio's exercise of the
put, to deliver to the Underlying Theme Portfolio an amount of cash if the
closing level of the index upon which the put is based is less than the exercise
price of the put, which amount of cash is determined by the multiplier, as
described above for calls. When the Underlying Theme Portfolio writes a put on
an index, it receives a premium and the purchaser has the right, prior to the
expiration date, to require the Underlying Theme Portfolio to deliver to it an
amount of cash equal to the difference between the closing level of the index
and the exercise price times the multiplier, if the closing level is less than
the exercise price.
 
The risks of investment in index options may be greater than options on
securities. Because index options are settled in cash, when an Underlying Theme
Portfolio writes a call on an index it cannot provide in advance for its
potential settlement obligations by acquiring and holding the underlying
securities. An Underlying Theme Portfolio can offset some of the risk of writing
a call index option position by holding a diversified portfolio of securities
similar to those on which the underlying index is based. However, an Underlying
Theme Portfolio cannot, as a practical matter, acquire and hold a portfolio
containing exactly the same securities as underlie the index and, as a result,
bears a risk that the value of the securities held will vary from the value of
the index.
 
Even if an Underlying Theme Portfolio could assemble a securities portfolio that
exactly reproduced the composition of the underlying index, it still would not
be fully covered from a risk standpoint because of the "timing risk" inherent in
writing index options. When an index option is exercised, the amount of cash
that the holder is entitled to receive is determined by the difference between
the exercise price and the closing index level on the date when the option is
exercised. As with other kinds of options, the Underlying Theme Portfolio, as
the call writer, will not know that it has been assigned until the next business
day at the earliest. The time lag between exercise and notice of assignment
poses no risk for the writer of a covered call on a specific underlying
security, such as common stock, because there the writer's obligation is to
deliver the underlying security, not to pay its value as of a fixed time in the
past. So long as the writer already owns the underlying security, it can satisfy
its settlement obligations by simply delivering it, and the risk that its value
may have declined since the exercise date is borne by the exercising holder. In
contrast, even if the writer of an index call holds securities that exactly
match the composition of the underlying index, it will not be able to satisfy
its assignment obligations by delivering those securities against payment of the
exercise price. Instead, it will be required to pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that it
has been assigned, the 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.
 
                  Statement of Additional Information Page 10
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
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.

                             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. See "Taxes."
    
 
                  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
<PAGE>
                          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. 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.

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
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        (6) Borrow money except from banks not in excess of 33 1/3% of the value
    of each Portfolio's total assets, (including the amount borrowed), less all
    liabilities and indebtedness (other than the borrowing). This restriction
    shall not prevent any Portfolio from entering into reverse repurchase
    agreements, provided that reverse repurchase agreements, and any other
    transactions constituting borrowing by a Portfolio may not exceed one-third
    of that Portfolio's total assets. Transactions involving options, futures
    contracts, options on futures contracts and forward currency contracts, as
    described in 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 Global Infrastructure Portfolio's
    and Global Natural Resources Portfolio's total assets, such Portfolio will
    not make any additional investments); and
    
 
        (8) Invest more than 10% of its total assets in shares of other
    investment companies and may not invest more than 5% of its total assets in
    any one investment company or acquire more than 3% of the outstanding voting
    securities of any one investment company.
 
Investors should refer to the Underlying Theme Funds' prospectus for further
information with respect to the investment objective of each Feeder Fund, which
may not be changed without the approval of its shareholders, and its
corresponding Portfolio's investment objective, which may be changed without the
approval of its interestholders, and other investment policies, techniques and
limitations, which may or may not be changed without interestholder approval.
 
HEALTH CARE FUND
 
The Health Care Fund has adopted the following investment limitations as
fundamental policies, which (unless otherwise noted) may not be changed without
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

        (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.

Fund.
 
DISTRIBUTION SERVICES RELATING TO THE FUND

                            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 for Fund shares, other than by wire transfer, must be
made by check or money order drawn on a U.S. bank. Checks or money orders must
be payable in U.S. dollars.
    
 
   
As a condition of this offering, if an order to purchase Advisor Class shares is
canceled due to nonpayment (for example, on account of a check returned for "not
sufficient funds"), the person who made the order will be responsible for any
loss incurred by the Underlying Theme Fund by reason of such cancellation, and
if such purchaser is a shareholder, the Fund shall have the authority as agent
of the shareholder to redeem shares in his or her account at their then-current
net asset

value per share to reimburse the Fund for the loss incurred. Investors whose
purchase orders have been canceled due to nonpayment may be prohibited from
placing future orders.
 
The Fund reserves the right at any time to waive or increase the minimum
requirements applicable to initial or subsequent investments with respect to any
person or class of persons. An order to purchase shares is not binding on the
Fund until it has been confirmed in writing by the Transfer Agent (or other
arrangements made with the Fund, in the case of orders utilizing wire transfer
of funds, as described above) and payment has been received. To protect existing
shareholders, the Fund reserves the right to reject any offer for a purchase of
shares by any individual.
 
SALES OUTSIDE THE UNITED STATES
Sales of Fund shares made through brokers outside the United States will be at
net asset value plus a sales commission, if any, established by that broker or
by local law.
 
   
INDIVIDUAL RETIREMENT ACCOUNTS ("IRAs") AND OTHER TAX-DEFERRED PLANS
    
 
   
IRAs: If you have earned income from employment (including self-employment), you
can contribute each year to an IRA up to the lesser of (1) $2,000 for yourself
or $4,000 for you and your spouse, regardless of whether your spouse is
employed, or (2) 100% of compensation. Some individuals may be able to take an
income tax deduction for the contribution. Regular contributions may not be made
for the year you become 70 1/2 or thereafter. Unless your and your spouse's
earnings exceed a certain level, you also may establish an "education IRA"
and/or a "Roth IRA." Although contributions to these new types of IRAs are
nondeductible, withdrawals from them will be tax-free under certain
circumstances. Please consult your tax advisor for more information. IRA
applications are available from brokers or GT Global.
    
 
   
ROLLOVER IRAs: Individuals who receive distributions from qualified retirement
plans (other than required distributions) and who wish to keep their savings
growing tax-deferred can roll over (or make a direct transfer of) their
distribution to a Rollover IRA. These accounts can also receive rollovers or
transfers from an existing IRA. If an "eligible rollover distribution" from a
qualified employer-sponsored retirement plan is not directly rolled over to an
IRA (or certain qualified plans), withholding at the rate of 20% will be
required for federal income tax purposes. A distribution from a qualified plan
that is not an "eligible rollover distribution," including a distribution that
is one of a series of substantially equal periodic payments, generally is
subject to regular wage withholding or withholding at the rate of 10% (depending
on the type and amount of the distribution), unless you elect not to have any
withholding apply. Please consult your tax advisor for more information.
    
 
   
SEP-IRAs: Simplified employee pension plans ("SEPs" or "SEP-IRAs") provide
self-employed individuals (and any eligible employees) with benefits similar to
Keogh plans (i.e., self-employed individual retirement plans) or Code Section
401(k) plans, but with fewer administrative requirements and therefore 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.
    
 
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 continue to qualify for treatment as a regulated investment company ("RIC")
under the Code, the Fund must distribute to its shareholders for each taxable
year at least 90% of its investment company taxable income (consisting generally
of net investment income and net short-term capital gain) ("Distribution
Requirement") and must meet several additional requirements. These requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each taxable year from dividends, interest, payments with respect to securities
loans and gains from the sale or other disposition of securities, or other
income derived with respect to its business of investing in securities; (2) at
the close of each quarter of the Fund's taxable year, at least 50% of the value
of its total assets must be represented by cash and cash items, U.S. government
securities, securities of other RICs (including the Underlying Theme Funds) and
other securities, with these other securities limited, in respect of any one
issuer, to an amount that does not exceed 5% of the value of the Fund's total
assets and that does not represent more than 10% of the issuer's outstanding
voting securities; and (3) at the close of each quarter of the Fund's taxable
year, not more than 25% of the value of its total assets may be invested in
securities (other than U.S. government securities or the securities of other
RICs, including the Underlying Theme Funds) of any one issuer.
    
 
   
The Fund will invest its assets in shares of the Underlying Theme Funds, cash
and money market instruments. Accordingly, the Fund's income will consist of
distributions from the Underlying Theme Funds, net gains realized from the
disposition of Underlying Theme Fund shares and interest. If an Underlying Theme
Fund qualifies for treatment as a RIC under the Code -- each has done so for its
past taxable years and intends to continue to do so for its current and future
taxable years -- (1) dividends paid to the Fund from the Underlying Theme Fund's
investment company taxable income (which may include net gains from certain
foreign currency transactions) will be taxable to the Fund as ordinary income to
    
 
                  Statement of Additional Information Page 32
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
the extent of the Underlying Theme Fund's earnings and profits and (2)
distributions paid to the Fund from the Underlying Theme Fund's net capital gain
(the excess of net long-term capital gain over net short-term capital loss),
when designated as such, will be taxable to the Fund as long-term capital gains,
regardless of how long the Fund has held the Underlying Theme Fund's shares.
 
   
If shares of an Underlying Theme Fund are purchased within 30 days before or
after redeeming other shares of that Underlying Theme Fund (whether pursuant to
a rebalancing of the Fund's portfolio or otherwise) at a loss, all or a part of
the loss will not be deductible by the Fund and instead will increase its basis
for the newly purchased shares.
    
 
Although an Underlying Theme Fund will be eligible to elect to "pass-through" to
its shareholders (including the Fund) the benefit of the foreign tax credit with
respect to any foreign and U.S. possessions income taxes it pays if more than
50% in the value of its total assets at the close of any taxable year consists
of securities of foreign corporations, the Fund will not qualify to pass that
benefit through to its shareholders because of its inability to satisfy that
asset test.
 
The Fund will be subject to a nondeductible 4% excise tax to the extent it fails
to distribute by the end of any calendar year substantially all of its ordinary
income for that year and capital gain net income for the one-year period ending
on October 31 of that year, plus certain other amounts.
 
TAXATION OF THE FUND'S SHAREHOLDERS
   
Dividends and other distributions declared by the Fund, and payable to
shareholders of record as of a date, in October, November or December of any
year will be deemed to have been paid by the Fund and received by the
shareholders on December 31 of that year if the distributions are paid by the
Fund during the following January. Accordingly, those distributions will be
taxed to shareholders for the year in which that December 31 falls.
    
 
   
A portion of the dividends from the Fund's investment company taxable income
(whether paid in cash or reinvested in additional shares) may be eligible for
the dividends-received deduction allowed to corporations. The eligible portion
may not exceed the total of the Fund's share of the aggregate dividends received
by each Underlying Theme Fund from U.S. corporations. However, dividends
received by a corporate shareholder and deducted by it pursuant to the
dividends-received deduction may be subject indirectly to the alternative
minimum tax.
    
 
If Fund shares are sold at a loss after being held for six months or less, the
loss will be treated as long-term, instead of short-term, capital loss to the
extent of any capital gain distributions received on those shares. Investors
also should be 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 as a RIC under subchapter M of the Internal
Revenue Code, or failure to timely file any required tax returns or other
filings.

in their opinion appearing herein, and are included in reliance upon such

USE OF NAME

names and has reserved the right to withdraw its consent to the use of such
names by the Trust at any time or to grant the use of such names to any other

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

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, Class C 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, Class C 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

    1,000 companies in Europe, Australia and the Far East.
 
        (9) Morgan Stanley Capital International All Country (AC) World Index
    ("MSCI"). The MSCI is a broad, unmanaged index of global stock prices,
    currently comprising 2500 different issuers, located in 47 countries, and
    grouped in 38 separate industries.

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

The Fund may describe in its sales material and advertisements how an investor
may invest in GT Global Mutual Funds through various retirement plans or other
programs that offer deferral of income taxes on investment earnings and to which
an investor may make deductible contributions. Because of their advantages,
these retirement accounts and plans and programs may produce returns superior to
comparable non-retirement investments. For example, a $10,000 investment earning
a taxable return of 10% annually would have an after-tax value of $17,976 after
ten years, assuming tax was deducted from the return each year at a 39.6% rate.
An equivalent tax-deferred investment would have an after-tax value of $19,626
after ten years, assuming tax was deducted at a 39.6% rate from the deferred
earnings at the end of the ten-year period. In sales material and
advertisements, the Fund may also discuss these plans and programs. See
"Information relating to Sales and Redemptions -- Individual Retirement Accounts
("IRAs") and Other Tax Deferred Plans."
    
 
GT Global may from time to time in its sales materials and advertising discuss
the risks inherent in investing. The major types of investment risk are market
risk, industry risk, credit risk, interest rate risk, liquidity risk and
inflation risk. Risk represents the possibility that you may lose some or all of
your investment over a period of time. A basic tenet of investing is the greater
the potential reward, the greater the risk.

In advertising and sales materials, GT Global may make reference to or discuss
its products, services and accomplishments. Among these accomplishments are that
in 1983 the Manager provided assistance to the government of Hong Kong in
linking its currency to the U.S. dollar, and that in 1987 Japan's Ministry of
Finance licensed LGT Asset Management Ltd. as one of the first foreign
discretionary investment managers for Japanese investors. Such accomplishments,
however, should not be viewed as an endorsement of the Manager by the government
of Hong Kong, Japan's Ministry of Finance or any other government or government
agency. Nor do any such accomplishments of the Manager provide any assurance
that the GT Global Mutual Funds' investment objectives will be achieved.
 
GT GLOBAL ADVANTAGE
As part of Liechtenstein Global Trust, GT Global continues a 75-year tradition
of service to individuals and institutions. Today we bring investors a
combination of experience, worldwide resources, a global perspective, investment
talent and a time tested investment discipline. With investment professionals in
nine offices worldwide, we witness world events and economic developments
firsthand.
 
The key to achieving consistent results is following a disciplined investment
process. Our approach to asset allocation takes advantage of GT Global's
worldwide presence and global perspective. Our "macroeconomic" worldview
determines our overall strategy of regional, country and sector allocations. Our
bottom up process of security selection combines fundamental research with
quantitative analysis through our proprietary models.
 
Built in checks and balances strengthen the process, enhancing professional
experience and judgment with an objective assessment of risk. Ultimately, each
security we select has passed a ranking system that helps our portfolio teams
determine when to buy and when to sell.
 
   
GT Global describes the major stages of economic development as revolving in a
"virtuous cycle." From time to time, each Fund and GT Global may discuss the
virtuous cycle in its sales literature and advertising. This cycle operates
worldwide, forcing companies to become increasingly competitive in an
ever-expanding global marketplace. GT Global has identified the following
sequential stages within the virtuous cycle:
    
 
   
FALLING BORDERS AND TRADE BARRIERS: Barriers between countries diminish,
increasing the potential for world trade and promoting global competition.
    
 
   
CAPITAL FLOWS FROM DEVELOPED MARKETS TO EMERGING MARKETS: As barriers fall,
restrictions on the free movement of capital in and out of a country are often
reduced or removed. The flow of money from developed to developing markets gains
momentum.
    
 
   
INDUSTRIALIZATION OF EMERGING MARKETS: With capital flowing across borders, many
developing nations are able to quickly begin their process of industrialization.
    
 
   
INCREASED DEMAND FOR GLOBAL CONSUMER PRODUCTS: As people in emerging markets
experience rising standards of living due to increased industrialization, they
demand more consumer products which can help spur global trade flows.
    
 
   
GT Global believes that we increasingly live in a world without boundaries in
terms of trade, competition and investment opportunities. Therefore, GT Global
believes it's becoming more relevant to look at investing in terms of industrial
groupings, or themes, as an alternative to the traditional, primary focus on
regions. GT Global believes such themes make movement possible between stages in
the virtuous cycle of economic progress.
    
 
   
GENERAL INFORMATION ABOUT THE UNDERLYING THEME PORTFOLIOS
    
   
Each Underlying Theme Portfolio may invest worldwide across industries within
the Portfolio's area of concentration without national or regional restrictions.
The ability of each Underlying Theme Portfolio to invest worldwide may allow the
portfolio managers to select industries in different economic cycles and varying
stages of development, though there is no assurance that the managers will be
successful in this selection.
    
 
   
Each Underlying Theme Portfolio's area of concentration reflects the underlying
theme of the Portfolio. GT Global believes that there are certain social,
political and economic trends that may benefit one or more industries within an
Underlying Theme Portfolio's area of concentration. Of course, there is no
assurance that any of the Funds will benefit as a result.

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

        LATIN AMERICAN TELECOM REPORT
    
 
   
    / / Telegeography and other publications
    
 
   
DEREGULATION IN THE UNITED STATES
    
   
The United States has been the bellwether for deregulation of the telephone
industry. The divestiture of the Bell System from American Telephone and
Telegraph has produced competing companies in the United States. Such U.S.
market-driven competition has, for example, led to lower costs for consumers
which in turn led to greater consumer usage and to higher industrywide revenues.
The Manager expects this scenario to continue to benefit such companies in the
U.S. and similarly to be realized by the established telecommunications
companies in established economies, although no assurances can be made in this
regard.

                          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.
 
                  Statement of Additional Information Page 44
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        Caa -- Poor standing. Such issues may be in default or there may be
    present elements of danger with respect to principal or interest.
 
        Ca -- Speculative in a high degree. Such issues are often in default or
    have other marked shortcomings.
 
        C -- Lowest rated class of bonds. Issues so rated can be regarded as
    having extremely poor prospects of ever attaining any real investment
    standing.
 
ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.
 
Should no rating be assigned, the reason may be one of the following:
 
    1.  An application for rating was not received or accepted.
 
    2.  The issue or issuer belongs to a group of securities or companies that
       are not rated as a matter of policy.
 
    3.  There is a lack of essential data pertaining to the issue or issuer.
 
    4.  The issue was privately placed, in which case the rating is not
       published in Moody's publications.
 
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
 
Note: Moody's applies numerical modifiers 1, 2 and 3 in each generic rating
classification from Aa to B in its corporate bond rating system. The modifier 1
indicates that the company ranks in the higher end of its generic rating
category; the modifier 2 indicates a mid-range ranking; and the modifier 3
indicates that the issue ranks in the lower end of its generic rating category.
 
S&P rates the securities debt of various entities in categories ranging from
"AAA" to "D" according to quality. Investment grade ratings are the first four
categories:
 
        AAA -- Highest rating. Capacity to pay interest and repay principal is
    extremely strong.
 
        AA -- Very strong capacity to pay interest and repay principal and
    differs from the higher rated issues only in a small degree.
 
        A -- Has a strong capacity to pay interest and repay principal although
    it is somewhat more susceptible to the adverse effects of changes in
    circumstances and economic conditions than debt in higher rated categories.
 
        BBB -- Regarded as having adequate capacity to pay interest and repay
    principal. Whereas it normally exhibits adequate protection parameters,
    adverse economic conditions or changing circumstances are more likely to
    lead to a weakened capacity to pay interest and repay principal for debt in
    this category than in higher rated categories.
 
        BB, B, CCC, CC, C -- Debt rated "BB," "B," "CCC," "CC," and "C" is
    regarded, on balance, as predominantly speculative with respect to capacity
    to pay interest and repay principal in accordance with the terms of the
    obligation. "BB" indicates the lowest degree of speculation and "C" the
    highest degree of speculation. While such debt will likely have some quality
    and protective characteristics, these are outweighed by large uncertainties
    or major risk exposures to adverse conditions.
 
        BB -- Has less near-term vulnerability to default than other speculative
    issues. However, it faces major ongoing uncertainties or exposure to adverse
    business, financial, or economic conditions which could lead to inadequate
    capacity to meet timely interest and principal payments. The "BB" rating
    category is also used for debt subordinated to senior debt that is assigned
    an actual or implied "BBB-" rating.
 
        B -- Has a greater vulnerability to default but currently has the
    capacity to meet interest payments and principal repayments. Adverse
    business, financial, or economic conditions will likely impair capacity or
    willingness to pay interest and repay principal. The "B" rating category is
    also used for debt subordinated to senior debt that is assigned an actual or
    implied "BB" or "BB-" rating.
 
        CCC -- Has a currently identifiable vulnerability to default, and is
    dependent upon favorable business, financial, and economic conditions to
    meet timely payment of interest and repayment of principal. In the event of
    adverse business, financial, or economic conditions, it is not likely to
    have the capacity to pay interest and repay principal. The "CCC" rating
    category is also used for debt subordinated to senior debt that is assigned
    an actual or implied "B" or "B-" rating.
 
                  Statement of Additional Information Page 45
<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.

ITEM 27. INDEMNIFICATION
 
    Article X of the Registrant's Declaration of Trust provides for
indemnification of certain persons acting on behalf of the Trust.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended ("1933 Act"), may be permitted to Trustees, officers, and
controlling persons by the Registrant's Declaration of Trust, By-Laws, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission ("Commission") such indemnification is against public
policy as expressed in the 1933 Act, and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a Trustee, officer, or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such Trustee, officer, or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to the court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the 1933 Act
and will be governed by the final adjudication of such issues.
