THE FOLLOWING SUPPLEMENTS THE DISCUSSION UNDER "MANAGEMENT" WITH RESPECT TO GT
GLOBAL SERIES TRUST (THE "COMPANY"):
 
On January 30, 1998, Liechtenstein Global Trust ("LGT"), the indirect parent
organization of Chancellor LGT Asset Management, Inc. (the "Manager"), entered
into an agreement with AMVESCAP PLC ("AMVESCAP") pursuant to which AMVESCAP will
acquire LGT's Asset Management Division, which includes the Manager. AMVESCAP is
a holding company formed in 1997 by the merger of INVESCO PLC and A I M
Management Group Inc. Consummation of the transaction is subject to a number of
contingencies, including regulatory approvals. Because the transaction would
constitute an assignment of the Company's management agreement under the
Investment Company Act of 1940 (and, therefore, a termination of such
agreement), it is anticipated that the approval of the Company's Board of
Trustees and the Company's shareholders of a new management arrangement will be
sought. The Manager anticipates that the new management arrangement will be
presented for shareholder approval, and anticipates that the transaction will
close, on or about May 31, 1998.

THE FOLLOWING SUPPLEMENTS THE DISCUSSION UNDER "MANAGEMENT" WITH RESPECT TO GT
GLOBAL SERIES TRUST (THE "COMPANY"):
 
On January 30, 1998, Liechtenstein Global Trust ("LGT"), the indirect parent
organization of Chancellor LGT Asset Management, Inc. (the "Manager"), entered
into an agreement with AMVESCAP PLC ("AMVESCAP") pursuant to which AMVESCAP will
acquire LGT's Asset Management Division, which includes the Manager. AMVESCAP is
a holding company formed in 1997 by the merger of INVESCO PLC and A I M
Management Group Inc. Consummation of the transaction is subject to a number of
contingencies, including regulatory approvals. Because the transaction would
constitute an assignment of the Company's management agreement under the
Investment Company Act of 1940 (and, therefore, a termination of such
agreement), it is anticipated that the approval of the Company's Board of
Trustees and the Company's shareholders of a new management arrangement will be
sought. The Manager anticipates that the new management arrangement will be
presented for shareholder approval, and anticipates that the transaction will
close, on or about May 31, 1998.

                                    POLICIES
 
- --------------------------------------------------------------------------------
 
INVESTMENT POLICIES OF THE FUND
The following supplements the information contained in the Prospectus concerning
the investment policies of the Fund.
 
U.S. GOVERNMENT SECURITIES. The Fund may invest in various direct obligations of
the U.S. Treasury and obligations issued or guaranteed by the U.S. government or
one  of  its  agencies  or  instrumentalities  (collectively,  "U.S.  government
securities"). Among the U.S. government securities that may be held by the  Fund
are  securities that are  supported by the  full faith and  credit of the United
States; securities that are supported by the right of the issuer to borrow  from
the U.S. Treasury; and securities that are supported solely by the credit of the
instrumentality.
 
REPURCHASE   AGREEMENTS.  The  Fund  may  invest  in  repurchase  agreements.  A
repurchase agreement is  a transaction  in which the  Fund purchases  securities
from a bank or recognized securities dealer and simultaneously commits to resell
the  securities to the bank or dealer on  an agreed-upon date or upon demand and
at a price reflecting a market rate of interest unrelated to the coupon rate  or
maturity  of  the  purchased  securities.  The  Fund  maintains  custody  of the
underlying securities prior  to their  repurchase; thus, the  obligation of  the
bank  or dealer to pay the repurchase price on the date agreed to is, in effect,
secured by such securities. If  the value of these  securities is less than  the
repurchase price, plus any agreed-upon additional amount, the other party to the
agreement must provide additional collateral so that at all times the collateral
is  at  least equal  to the  repurchase price,  plus any  agreed-upon additional
amount. The difference between the total  amount to be received upon  repurchase
of  the securities and the  price that was paid by  the Fund upon acquisition is
accrued as  interest  and included  in  its net  investment  income.  Repurchase
agreements  carry  certain  risks  not  associated  with  direct  investments in
securities, including possible declines  in the market  value of the  underlying
securities  and delays and costs to the Fund  if the other party to a repurchase
agreement becomes insolvent.
 
INVESTMENT POLICIES OF THE UNDERLYING THEME FUNDS
The following supplements the information contained in the Prospectus concerning
the investment  policies and  limitations of  the Underlying  Theme Funds.  More
information  about the investment  policies and restrictions  and the investment
limitations of each Underlying Theme Fund  is set forth in the Underlying  Theme
Funds' prospectus and statement of additional information.
 
The Underlying Theme Funds are diversified series of G.T. Investment Funds, Inc.
(the  "Company"), a  registered open-end  management investment  company. The GT
Global Consumer  Products and  Services Fund  ("Consumer Products  and  Services
Fund"), GT Global Financial Services Fund ("Financial Services Fund"), GT Global
Infrastructure  Fund ("Infrastructure  Fund"), and  GT Global  Natural Resources
Fund ("Natural Resources Fund") (each,  a "Feeder Fund," and, collectively,  the
"Feeder Funds") each invests all of its investable assets in the Global Consumer
Products  and Services  Portfolio, Global  Financial Services  Portfolio, Global
Infrastructure Portfolio,  and  Global  Natural  Resources  Portfolio  (each,  a
"Portfolio," and, collectively, the "Portfolios"), respectively.
 
Each  Portfolio is  a subtrust (a  "series") of Global  Investment Portfolio (an
open-end management investment  company) with  an investment  objective that  is
identical  to  that of  its corresponding  Underlying  Theme Fund.  Whenever the
phrase "all of the Underlying Theme Fund's investable assets" is used herein, it
means that the  only investment securities  held by  a Feeder Fund  will be  its
interest  in  its  corresponding  Portfolio.  A  Feeder  Fund  may  withdraw its
investment in its corresponding Portfolio at any time, if the Company's Board of
Directors determines that it is in the best interests of the Feeder Fund and its
shareholders to do so. Upon any such withdrawal, a Feeder Fund's assets would be
invested in  accordance  with  the  investment  policies  of  its  corresponding
Portfolio described below and in the Underlying Theme Funds' prospectus.
 
The  investment objective of  each Feeder Fund is  long-term capital growth. The
investment objectives of the GT Global Health Care Fund ("Health Care Fund") and
the GT Global Telecommunications Fund ("Telecommunications Fund") are  long-term
capital  appreciation and long-term capital growth, respectively. The Portfolios
and the Health Care Fund and the Telecommunications Fund, together, are referred
to herein as the "Underlying Theme Portfolios."
 
                   Statement of Additional Information Page 2
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
SELECTION OF EQUITY INVESTMENTS.  With respect to  the Global Natural  Resources
Portfolio,  the Manager  has identified four  areas that it  expects will create
investment opportunities: (i)  improving supply/demand  fundamentals, which  may
result  in higher  commodity prices;  (ii) privatization  of state-owned natural
resource businesses; (iii) management which can improve production  efficiencies
without  correspondingly increasing commodity prices; and (iv) service companies
with emerging technologies  that can enhance  productivity or reduce  production
costs.  Of course,  there is  no certainty that  these factors  will produce the
anticipated results.
 
With respect to  the Telecommunications  Fund, the Manager  has identified  four
areas  that it expects will create investment opportunities: (i) deregulation of
companies in  the industry,  which  will allow  competition to  promote  greater
efficiencies;  (ii) privatization of  state-owned telecommunications businesses;
(iii) development of infrastructure in underdeveloped countries and upgrading of
services in other countries;  and (iv) emerging  technologies that will  enhance
productivity  and reduce  costs in  the telecommunications  industry. Of course,
there is no certainty that these factors will produce the anticipated results.
 
There may  be times  when, in  the opinion  of the  Manager, prevailing  market,
economic  or  political  conditions  warrant  reducing  the  proportion  of  the
Underlying Theme Portfolios' assets invested in equity securities and increasing
the proportion held in cash  (U.S. dollars, foreign currencies or  multinational
currency  units) or  invested in  debt securities  or high  quality money market
instruments  issued  by  corporations,  or  the  United  States,  or  a  foreign
government.  A portion of each Underlying Theme Portfolio's assets normally will
be held  in cash  (U.S. dollars,  foreign currencies  or multinational  currency
units)  or invested in foreign or domestic high quality money market instruments
pending investment of proceeds from new sales of Underlying Theme Fund shares to
provide for ongoing expenses and to satisfy redemptions.
 
For  each  Underlying  Theme  Portfolio's  investment  purposes,  an  issuer  is
typically  considered as located in a particular  country if it (a) is organized
under the laws of or  has its principal office in  a particular country, or  (b)
normally  derives  50% or  more  of its  total  revenues from  business  in that
country, provided  that, in  the  Manager's view,  the  value of  such  issuer's
securities  will tend to reflect such  country's development to a greater extent
than developments elsewhere. However, these  are not absolute requirements,  and
certain  companies incorporated  in a particular  country and  considered by the
Manager to be located in that country may have substantial foreign operations or
subsidiaries and/or export sales exceeding in  size the assets or sales in  that
country.
 
In  certain  countries,  governmental  restrictions  and  other  limitations  on
investment may affect a Underlying Theme  Portfolio's ability to invest in  such
countries. In addition, in some instances only special classes of securities may
be  purchased by  foreigners and  the market  prices, liquidity  and rights with
respect to those securities may vary from shares owned by nationals. The Manager
is not aware at this time of the existence of any investment or exchange control
regulations which might  substantially impair the  operations of the  Underlying
Theme  Portfolios as  described in  the Underlying  Theme Funds'  prospectus and
statement of additional  information. Restrictions may  in the future,  however,
make it undesirable to invest in certain countries. None of the Underlying Theme
Portfolios  has a present intention of  making any significant investment in any
country or stock market in which the Manager considers the political or economic
situation to threaten  a Underlying  Theme Portfolio with  substantial or  total
loss of its investment in such country or market.
 
INVESTMENTS  IN OTHER INVESTMENT COMPANIES.  Each Underlying Theme Portfolio may
invest in the securities of investment  companies within the limitations of  the
Investment  Company Act of 1940, as  amended (the "1940 Act"). These limitations
currently provide that, in general,  an Underlying Theme Portfolio may  purchase
shares  of  an investment  company unless  (a)  such a  purchase would  cause an
Underlying Theme Portfolio to  own in the  aggregate more than  3% of the  total
outstanding  voting stock of the investment company or (b) such a purchase would
cause the Underlying Theme Portfolio to have more than 5% of its assets invested
in the  investment  company or  more  than 10%  of  its assets  invested  in  an
aggregate  of all such  investment companies. The  foregoing restrictions do not
apply to the investment of the  Feeder Funds in their corresponding  Portfolios.
Investment  in  closed-end  investment  companies  may  involve  the  payment of
substantial premiums above  the value of  such companies' portfolio  securities.
Each  Underlying Theme  Portfolio does not  intend to invest  in such investment
companies unless, in the judgment of the Manager, the potential benefits of such
investments justify the payment of any  applicable premiums. The return on  such
securities  will be reduced  by operating expenses  of such companies, including
payments to the investment managers of those investment companies.
 
DEPOSITORY RECEIPTS.  An  Underlying  Theme Portfolio  may  hold  securities  of
foreign  issuers in the form of  American Depository Receipts ("ADRs"), American
Depository Shares ("ADSs")  and European Depository  Receipts ("EDRs") or  other
securities  convertible  into  securities  of  eligible  foreign  issuers. These
securities may  not necessarily  be  denominated in  the  same currency  as  the
securities  for which they may be exchanged.  ADRs and ADSs are typically issued
by an  American bank  or  trust company  and  evidence ownership  of  underlying
securities issued by a foreign corporation. EDRs,
 
                   Statement of Additional Information Page 3
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
which are sometimes referred to as Continental Depository Receipts ("CDRs"), are
issued  in Europe  typically by foreign  banks and trust  companies and evidence
ownership of either foreign or domestic securities. Generally, ADRs and ADSs  in
registered  form are  designed for  use in U.S.  securities markets  and EDRs in
bearer form are designed for use in European securities markets. For purposes of
each Underlying  Theme  Portfolio's  investment policies,  an  Underlying  Theme
Portfolio's  investments in ADRs, ADSs and EDRs will be deemed to be investments
in the equity securities representing  securities of foreign issuers into  which
they may be converted.
 
ADR  facilities may be established as either "unsponsored" or "sponsored." While
ADRs issued under these  two types of facilities  are in some respects  similar,
there  are distinctions between  them relating to the  rights and obligations of
ADR holders and the practices of market participants. A depository may establish
an unsponsored  facility  without  participation by  (or  even  necessarily  the
acquiescence  of) the issuer of the deposited securities, although typically the
depository requests a  letter of  non-objection from  such issuer  prior to  the
establishment  of the facility.  Holders of unsponsored  ADRs generally bear all
the costs  of such  facilities. The  depository usually  charges fees  upon  the
deposit  and withdrawal of the deposited securities, the conversion of dividends
into  U.S.  dollars,  the  disposition   of  non-cash  distributions,  and   the
performance  of  other  services.  The  depository  of  an  unsponsored facility
frequently is  under  no  obligation to  distribute  shareholder  communications
received  from the issuer of the  deposited securities or to pass-through voting
rights to ADR  holders in  respect of  the deposited  securities. Sponsored  ADR
facilities  are created in generally the  same manner as unsponsored facilities,
except that  the  issuer of  the  deposited  securities enters  into  a  deposit
agreement  with the  depository. The deposit  agreement sets out  the rights and
responsibilities of  the  issuer,  the  depository and  the  ADR  holders.  With
sponsored facilities, the issuer of the deposited securities generally will bear
some of the costs relating to the facility (such as dividend payment fees of the
depository),  although ADR holders continue to bear certain other costs (such as
deposit and withdrawal fees).  Under the terms  of most sponsored  arrangements,
depositories  agree  to distribute  notices of  shareholder meetings  and voting
instructions, and to provide shareholder communications and other information to
the ADR holders at the  request of the issuer  of the deposited securities.  The
Underlying Theme Portfolios may invest in both sponsored and unsponsored ADRs.
 
WARRANTS  OR RIGHTS. Warrants or  rights may be acquired  by an Underlying Theme
Portfolio in  connection with  other securities  or separately  and provide  the
Underlying  Theme Portfolio  with the  right to purchase  at a  later date other
securities of the issuer.
 
LENDING OF UNDERLYING THEME PORTFOLIO  SECURITIES. For the purpose of  realizing
additional income, each Underlying Theme Portfolio may make secured loans of its
securities  holdings  amounting  to  not  more than  30%  of  its  total assets.
Securities loans are made to broker/dealers or institutional investors  pursuant
to  agreements requiring that the loans be continuously secured by collateral at
least equal at all times  to the value of the  securities lent plus any  accrued
interest,  "marked to market" on a  daily basis. The Underlying Theme Portfolios
may pay reasonable administrative and custodial fees in connection with the loan
of their securities.  While the  securities loan is  outstanding, an  Underlying
Theme  Portfolio  will continue  to receive  the equivalent  of the  interest or
dividends paid by  the issuer  on the  securities, as  well as  interest on  the
investment  of the collateral  or a fee  from the borrower.  An Underlying Theme
Portfolio will have a right to call  each loan and obtain the securities  within
the  stated settlement period.  An Underlying Theme Portfolio  will not have the
right to vote equity securities while they are being lent, but it may call in  a
loan  in anticipation of  any important vote.  Loans will only  be made to firms
deemed by the Manager to be of good standing and will not be made unless, in the
judgment of the Manager,  the consideration to be  earned from such loans  would
justify the risk. The risks in lending Underlying Theme Portfolio securities, as
with other extensions of secured credit, consist of possible delays in receiving
additional  collateral or  in recovery  of the  securities and  possible loss of
rights in the collateral should the borrower fail financially.
 
COMMERCIAL  BANK  OBLIGATIONS.  For  the  purposes  of  each  Underlying   Theme
Portfolio's investment policies with respect to bank obligations, obligations of
foreign  branches of  U.S. banks  and of  foreign banks  are obligations  of the
issuing bank and may be general obligations of the parent bank. Such obligations
may, however, be limited by the terms of a specific obligation and by government
regulation. As with investments in  non-U.S. securities in general,  investments
in  the obligations of foreign  branches of U.S. banks  and of foreign banks may
subject each Underlying Theme Portfolio  to investment risks that are  different
in  some  respects from  those of  investments in  obligations of  U.S. issuers.
Although each  Underlying Theme  Portfolio  will typically  acquire  obligations
issued  and supported by the credit of U.S. or foreign banks having total assets
at the time of purchase of $1 billion or more, this $1 billion figure is not  an
investment  policy or  restriction of each  Underlying Theme  Portfolio. For the
purposes of calculation with respect to the  $1 billion figure, the assets of  a
bank will be deemed to include the assets of its U.S. and non-U.S. branches.
 
                   Statement of Additional Information Page 4

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

                         OPTIONS, FUTURES AND CURRENCY
                                   STRATEGIES
 
- --------------------------------------------------------------------------------
 
SPECIAL RISKS OF OPTIONS, FUTURES AND CURRENCY STRATEGIES
The  use by  the Underlying Theme  Portfolios of options,  futures contracts and
forward currency contracts ("Forward Contracts") involves special considerations
and risks, as described  below. Risks pertaining  to particular instruments  are
described in the sections that follow.
 
        (1)  Successful  use  of  most of  these  instruments  depends  upon the
    Manager's ability  to  predict  movements  of  the  overall  securities  and
    currency markets, which requires different skills than predicting changes in
    the prices of individual securities. While the Manager is experienced in the
    use  of these  instruments, there  can be  no assurance  that any particular
    strategy adopted will succeed.
 
        (2) There  might  be  imperfect correlation,  or  even  no  correlation,
    between  price  movements  of  an  instrument  and  price  movements  of the
    investments being hedged. For example, if the value of an instrument used in
    a short hedge  increased by less  than the  decline in value  of the  hedged
    investment,  the  hedge  would  not  be fully  successful.  Such  a  lack of
    correlation might  occur  due to  factors  unrelated  to the  value  of  the
    investments  being hedged,  such as  speculative or  other pressures  on the
    markets in  which the  hedging instrument  is traded.  The effectiveness  of
    hedges  using hedging  instruments on indices  will depend on  the degree of
    correlation between price movements in the index and price movements in  the
    investments being hedged.
 
        (3) Hedging strategies, if successful, can reduce risk of loss by wholly
    or  partially offsetting the negative  effect of unfavorable price movements
    in the investments being hedged. However, hedging strategies can also reduce
    opportunity for gain by  offsetting the positive  effect of favorable  price
    movements  in the  hedged investments. For  example, if  an Underlying Theme
    Portfolio entered into a short hedge because the Manager projected a decline
    in the price of  a security in the  Underlying Theme Portfolio's  portfolio,
    and  the  price  of that  security  increased  instead, the  gain  from that
    increase might be wholly or  partially offset by a  decline in the price  of
    the  hedging instrument.  Moreover, if the  price of  the hedging instrument
    declined by  more  than the  increase  in the  price  of the  security,  the
    Underlying
 
                   Statement of Additional Information Page 6
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
    Theme  Portfolio could  suffer a loss.  In either such  case, the Underlying
    Theme Portfolio would have been  in a better position  had it not hedged  at
    all.
 
        (4)  As described below, an Underlying Theme Portfolio might be required
    to maintain assets as "cover,"  maintain segregated accounts or make  margin
    payments  when it  takes positions  in instruments  involving obligations to
    third parties  (I.E.,  instruments other  than  purchased options).  If  the
    Underlying  Theme Portfolio were  unable to close out  its positions in such
    instruments, it might  be required to  continue to maintain  such assets  or
    accounts  or make such  payments until the position  expired or matured. The
    requirements might impair the Underlying Theme Portfolio's ability to sell a
    portfolio security or make an investment  at a time when it would  otherwise
    be favorable to do so, or require that the Underlying Theme Portfolio sell a
    portfolio   security  at  a  disadvantageous   time.  The  Underlying  Theme
    Portfolio's ability  to close  out  a position  in  an instrument  prior  to
    expiration or maturity depends on the existence of a liquid secondary market
    or,  in the  absence of such  a market,  the ability and  willingness of the
    other party to the transaction ("contra party") to enter into a  transaction
    closing out the position. Therefore, there is no assurance that any position
    can  be closed out at  a time and price that  is favorable to the Underlying
    Theme Portfolio.
 
WRITING CALL OPTIONS
Each Underlying Theme  Portfolio may  write (sell) call  options on  securities,
indices and currencies. Call options generally will be written on securities and
currencies  that, in the  opinion of the  Manager, are not  expected to make any
major price moves in the near future but that, over the long term, are deemed to
be attractive investments for the Underlying Theme Portfolios.
 
A call option  gives the  holder (buyer)  the right  to purchase  a security  or
currency  at a specified price (the exercise  price) at any time until (American
style) or on (European style) a certain  date (the expiration date). So long  as
the  obligation of  the writer  of a  call option  continues, he  or she  may be
assigned an exercise  notice, requiring  him or  her to  deliver the  underlying
security  or currency  against payment  of the  exercise price.  This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer  effects  a closing  purchase  transaction by  purchasing  an  option
identical to that previously sold.
 
Portfolio  securities or currencies on which call options may be written will be
purchased solely on the basis of investment considerations consistent with  each
Underlying  Theme Portfolio's investment objective.  When writing a call option,
an Underlying  Theme  Portfolio,  in  return  for  the  premium,  gives  up  the
opportunity  for  profit from  a price  increase in  the underlying  security or
currency above the exercise price, and retains the risk of loss should the price
of the  security  or  currency  decline.  Unlike  one  who  owns  securities  or
currencies  not  subject to  an  option, an  Underlying  Theme Portfolio  has no
control over  when it  may be  required  to sell  the underlying  securities  or
currencies,  since  most options  may  be exercised  at  any time  prior  to the
option's expiration. If  a call option  that an Underlying  Theme Portfolio  has
written  expires, it will realize a gain  in the amount of the premium; however,
such gain may  be offset  by a  decline in the  market value  of the  underlying
security  or currency during the option period. If the call option is exercised,
the Underlying Theme Portfolio will realize a gain or loss from the sale of  the
underlying  security  or currency,  which  will be  increased  or offset  by the
premium received. The Underlying Theme Portfolios do not consider a security  or
currency  covered by a call option to be "pledged" as that term is used in their
policies that limit the pledging or mortgaging of their assets.
 
Writing call options can serve as a limited short hedge because declines in  the
value  of the  hedged investment would  be offset  to the extent  of the premium
received  for  writing  the  option.  However,  if  the  security  or   currency
appreciates to a price higher than the exercise price of the call option, it can
be  expected that the option will be exercised and an Underlying Theme Portfolio
will be obligated  to sell  the security  or currency  at less  than its  market
value.
 
The  premium  that an  Underlying Theme  Portfolio receives  for writing  a call
option is deemed to constitute  the market value of  an option. The premium  the
Underlying Theme Portfolio will receive from writing a call option will reflect,
among  other things, the current market  price of the underlying investment, the
relationship of the exercise  price to such market  price, the historical  price
volatility of the underlying investment, and the length of the option period. In
determining whether a particular call option should be written, the Manager will
consider the reasonableness of the anticipated premium and the likelihood that a
liquid secondary market will exist for those options.
 
Closing  transactions  will be  effected  in order  to  realize a  profit  on an
outstanding call  option, to  prevent an  underlying security  or currency  from
being  called or  to permit  the sale  of the  underlying security  or currency.
Furthermore, effecting a  closing transaction  will permit  an Underlying  Theme
Portfolio  to write another  call option on the  underlying security or currency
with either a different exercise price or expiration date, or both.
 
                   Statement of Additional Information Page 7
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
Each Underlying Theme Portfolio  will pay transaction  costs in connection  with
the  writing  of  options  and  in  entering  into  closing  purchase contracts.
Transaction costs relating to  options activity are  normally higher than  those
applicable to purchases and sales of portfolio securities.
 
The  exercise price of the  options may be below, equal  to or above the current
market values of the  underlying securities, indices or  currencies at the  time
the  options are written. From  time to time, an  Underlying Theme Portfolio may
purchase an underlying security or currency for delivery in accordance with  the
exercise of an option, rather than delivering such security or currency from its
portfolio. In such cases, additional costs will be incurred.
 
An  Underlying Theme  Portfolio will  realize a  profit or  loss from  a closing
purchase  transaction  if  the  cost  of  the  transaction  is  less  or   more,
respectively,  than  the  premium  received  from  writing  the  option. Because
increases in the market price of a call option generally will reflect  increases
in  the market price of the underlying  security or currency, any loss resulting
from the repurchase of a call option is likely to be offset in whole or in  part
by  appreciation of the  underlying security or currency  owned by an Underlying
Theme Portfolio.
 
WRITING PUT OPTIONS
Each Underlying Theme Portfolio may write put options on securities, indices and
currencies. A put option gives  the purchaser of the  option the right to  sell,
and  the  writer (seller)  the  obligation to  buy,  the underlying  security or
currency at  the  exercise  price at  any  time  until (American  style)  or  on
(European  style) the  expiration date.  The operation  of put  options in other
respects, including their related risks and rewards, is substantially  identical
to that of call options.
 
An Underlying Theme Portfolio generally would write put options in circumstances
where the Manager wishes to purchase the underlying security or currency for the
Underlying  Theme Portfolio's holdings at a  price lower than the current market
price of the security or currency. In such event, an Underlying Theme  Portfolio
would  write a  put option  at an  exercise price  that, reduced  by the premium
received on the option, reflects the lower price it is willing to pay. Since the
Underlying Theme Portfolio  would also  receive interest on  debt securities  or
currencies  maintained to cover the exercise price of the option, this technique
could be used to  enhance current return during  periods of market  uncertainty.
The  risk in such a transaction would be that the market price of the underlying
security or currency  would decline below  the exercise price  less the  premium
received.
 
Writing  put options can serve as a  limited long hedge because increases in the
value of the  hedged investment would  be offset  to the extent  of the  premium
received   for  writing  the  option.  However,  if  the  security  or  currency
depreciates to a price lower than the  exercise price of the put option, it  can
be  expected  that the  put option  will  be exercised  and an  Underlying Theme
Portfolio will be obligated to purchase the security or currency at greater than
its market value.
 
PURCHASING PUT OPTIONS
Each Underlying Theme Portfolio may purchase put options on securities,  indices
and  currencies. As the  holder of a  put option, an  Underlying Theme Portfolio
would have the right to sell the underlying security or currency at the exercise
price at any time until (American  style) or on (European style) the  expiration
date.  An Underlying  Theme Portfolio may  enter into  closing sale transactions
with respect to  such options,  exercise such option  or permit  such option  to
expire.
 
Each  Underlying  Theme Portfolio  may purchase  a put  option on  an underlying
security or currency ("protective put") owned by the Underlying Theme  Portfolio
in  order to protect against an anticipated decline in the value of the security
or currency. Such hedge protection is provided  only during the life of the  put
option  when the Underlying Theme Portfolio, as the holder of the put option, is
able to  sell the  underlying security  or currency  at the  put exercise  price
regardless  of  any  decline  in  the  underlying  security's  market  price  or
currency's exchange  value.  The  premium  paid  for  the  put  option  and  any
transaction  costs would reduce any  profit otherwise available for distribution
when the security or currency is eventually sold.
 
An Underlying Theme Portfolio may  also purchase put options  at a time when  it
does not own the underlying security or currency. By purchasing put options on a
security  or currency it does not own,  that Underlying Theme Portfolio seeks to
benefit from  a  decline in  the  market price  of  the underlying  security  or
currency.  If the put option is not sold when it has remaining value, and if the
market price of the underlying security or currency remains equal to or  greater
than  the exercise price during the life of the put option, the Underlying Theme
Portfolio will lose its entire  investment in the put  option. In order for  the
purchase  of a put option  to be profitable, the  market price of the underlying
security or currency must decline sufficiently below the exercise price to cover
the premium and transaction costs,  unless the put option  is sold in a  closing
sale transaction.

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

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

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

                              RISK FACTORS OF THE
                          UNDERLYING THEME PORTFOLIOS
 
- --------------------------------------------------------------------------------
 
DEBT SECURITIES
The  value  of  the debt  securities  held  by each  Underlying  Theme Portfolio
generally will vary conversely with market interest rates. If interest rates  in
a  market fall, the value  of the debt securities  held by each Underlying Theme
Portfolio ordinarily will rise. If market interest rates increase, however,  the
debt  securities owned by each Underlying Theme Portfolio in that market will be
likely to decrease in value.
 
The Global  Consumer  Products  and Services  Portfolio,  Global  Infrastructure
Portfolio  and Global Natural Resources  Portfolio may each invest  up to 20% of
its  total  assets  in  debt  securities  rated  below  investment  grade.  Such
investments  involve a high  degree of risk. However,  those Portfolios will not
invest in debt securities  that are in  default as to  payment of principal  and
interest.
 
Debt  rated Baa  by Moody's Investors  Service, Inc. ("Moody")  is considered by
Moody's to have speculative characteristics. Debt rated  BB, B, CCC, CC or C  by
Standard  & Poor's, a  division of The McGraw-Hill  Companies, Inc. ("S&P"), and
debt rated  Ba,  B,  Caa, Ca  or  C  by  Moody's is  regarded,  on  balance,  as
predominantly  speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. For S&P,  BB
indicates the lowest degree of speculation for such lower quality debt and C the
highest  degree of speculation. For Moody's,  Baa indicates the lowest degree of
speculation for such lower quality debt and C the highest degree of speculation.
While such  lower quality  debt will  likely have  some quality  and  protective
characteristics,  these  are outweighed  by  large uncertainties  or  major risk
exposures to adverse conditions. Debt  rated C by Moody's  or S&P is the  lowest
rated  debt that is  not in default as  to principal or  interest, and issues so
rated can be regarded as having  extremely poor prospects of ever attaining  any
real  investment  standing. Lower  quality  debt securities  also  are generally
considered to be  subject to greater  risk than securities  with higher  ratings
with  regard  to a  deterioration of  general  economic conditions.  These lower
quality debt  securities are  the equivalent  of high  yield, high  risk  bonds,
commonly known as "junk bonds."
 
Ratings of debt securities represent the rating agency's opinion regarding their
quality  and are not a guarantee of quality. Rating agencies attempt to evaluate
the safety of principal and interest payments  and do not evaluate the risks  of
fluctuations  in market  value. Also,  rating agencies  may fail  to make timely
changes in credit ratings in response to subsequent events, so that an  issuer's
current financial condition may be better or worse than a rating indicates.
 
The  market values of  lower quality debt securities  tend to reflect individual
developments  of  the  issuer  to  a  greater  extent  than  do  higher  quality
securities,  which  react  primarily to  fluctuations  in the  general  level of
interest rates.  In addition,  lower quality  debt securities  tend to  be  more
sensitive  to economic conditions  and generally have  more volatile prices than
higher quality securities. Issuers of lower quality securities are often  highly
leveraged  and  may  not have  available  to  them more  traditional  methods of
financing. For example,  during an economic  downturn or a  sustained period  of
rising  interest rates, highly leveraged issuers of lower quality securities may
experience financial  stress. During  such periods,  such issuers  may not  have
sufficient  revenues to  meet their  interest payment  obligations. The issuer's
ability to  service its  debt  obligations may  also  be adversely  affected  by
specific  developments affecting the  issuer, such as  the issuer's inability to
 
                  Statement of Additional Information Page 15
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
meet specific projected business forecasts  or the unavailability of  additional
financing.  The  risk of  loss due  to  default by  the issuer  is significantly
greater for the holders of lower quality securities because such securities  are
generally  unsecured and may be subordinated to the claims of other creditors of
the issuer.
 
Lower quality  debt securities  of  corporate issuers  frequently have  call  or
buy-back features that permit the issuer to call or repurchase the security from
an  Underlying Theme  Portfolio. If  an issuer  exercises these  provisions in a
declining interest  rate market,  the  Underlying Theme  Portfolio may  have  to
replace  the security with  a lower yielding security,  resulting in a decreased
return for  investors. In  addition, the  Underlying Theme  Portfolios may  have
difficulty  disposing of lower  quality securities because they  may have a thin
trading market. There may be no established retail secondary market for many  of
these  securities,  and each  Underlying Theme  Portfolio anticipates  that such
securities could be sold  only to a limited  number of dealers or  institutional
investors. The lack of a liquid secondary market also may have an adverse impact
on  market prices  of such instruments  and may  make it more  difficult for the
Underlying Theme Portfolios to obtain accurate market quotations for purposes of
valuing their portfolio  investments. The Underlying  Theme Portfolios may  also
acquire  lower quality debt  securities during an  initial underwriting or which
are sold without registration under applicable securities laws. Such  securities
involve special considerations and risks.
 
In  addition to the foregoing, factors that  could have an adverse effect on the
market value of  lower quality  debt securities  in which  the Underlying  Theme
Portfolios  may invest include: (i) potential adverse publicity; (ii) heightened
sensitivity to general economic  or political conditions;  and (iii) the  likely
adverse  impact of a major economic recession. An Underlying Theme Portfolio may
also incur additional  expenses to the  extent it is  required to seek  recovery
upon  a default in the  payment of principal or  interest on portfolio holdings,
and the Underlying Theme Portfolio may have limited legal recourse in the  event
of a default.
 
The   Manager  attempts  to  minimize  the  speculative  risks  associated  with
investments in lower quality securities through credit analysis and by carefully
monitoring current trends  in interest rates,  political developments and  other
factors.
 
ILLIQUID SECURITIES
Each  Underlying Theme Portfolio may invest up  to 15% of its net assets (except
for the Health Care  Fund, which may invest  up to 10% of  its total assets)  in
illiquid  securities.  Securities may  be considered  illiquid if  an Underlying
Theme  Portfolio  cannot  reasonably  expect  within  seven  days  to  sell  the
securities  for approximately the amount at which it values such securities. See
"Investment Limitations of the Underlying Theme Funds and Portfolios." The  sale
of  illiquid securities, if they can be sold at all, generally will require more
time and  result in  higher  brokerage charges  or  dealer discounts  and  other
selling  expenses than  will the  sale of  liquid securities  such as securities
eligible for trading on U.S. securities  exchanges or in OTC markets.  Moreover,
restricted  securities, which may  be illiquid for  purposes of this limitation,
often sell, if at  all, at a  price lower than similar  securities that are  not
subject to restrictions on resale.
 
Illiquid  securities include those that are subject to restrictions contained in
the securities  laws of  other countries.  However, securities  that are  freely
marketable  in the country where  they are principally traded,  but would not be
freely marketable in the United States,  will not be considered illiquid.  Where
registration  is required, an Underlying Theme Portfolio may be obligated to pay
all or part of  the registration expenses and  a considerable period may  elapse
between  the time  of the  decision to  sell and  the time  the Underlying Theme
Portfolio may be permitted  to sell a security  under an effective  registration
statement.  If, during such a period, adverse market conditions were to develop,
the Underlying  Theme  Portfolio  might  obtain  a  less  favorable  price  than
prevailed when it decided to sell.
 
Not   all  restricted  securities   are  illiquid.  In   recent  years  a  large
institutional  market  has  developed  for  certain  securities  that  are   not
registered  under  the Securities  Act  of 1933,  as  amended (the  "1933 Act"),
including private placements, repurchase  agreements, commercial paper,  foreign
securities and corporate bonds and notes. These instruments are often restricted
securities  because  the  securities  are  sold  in  transactions  not requiring
registration. Institutional  investors generally  will not  seek to  sell  these
instruments  to the general public,  but instead will often  depend either on an
efficient institutional  market in  which such  unregistered securities  can  be
readily  resold  or on  an issuer's  ability  to honor  a demand  for repayment.
Therefore, the fact that there are  contractual or legal restrictions on  resale
to  the  general  public  or  certain institutions  is  not  dispositive  of the
liquidity of such investments.
 
Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the  1933 Act  for resales  of certain  securities to qualified
institutional buyers.  Institutional  markets  for  restricted  securities  have
developed  as a result of Rule 144A, providing both readily ascertainable values
for restricted securities and the ability to liquidate an investment to  satisfy
share redemption orders. Such markets include automated systems for the trading,
clearance  and  settlement of  unregistered securities  of domestic  and foreign
issuers, such as  the PORTAL  System sponsored  by the  National Association  of
Securities  Dealers,  Inc.  An insufficient  number  of  qualified institutional
buyers interested in purchasing Rule 144A-
 
                  Statement of Additional Information Page 16
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
eligible restricted securities held by  an Underlying Theme Portfolio,  however,
could  affect adversely the marketability of  such portfolio securities, and the
Underlying Theme  Portfolio  might  be  unable to  dispose  of  such  securities
promptly or at favorable prices.
 
With respect to liquidity determinations generally, the applicable Board has the
ultimate  responsibility for determining  whether specific securities, including
restricted securities pursuant to  Rule 144A under the  1933 Act, are liquid  or
illiquid.   Each  Board  has   delegated  the  function   of  making  day-to-day
determinations of  liquidity  to  the Manager,  in  accordance  with  procedures
approved  by that Board. The  Manager takes into account  a number of factors in
reaching liquidity  decisions, including  (i) the  frequency of  trading in  the
security,  (ii) the number of  dealers that make quotes  for the security, (iii)
the number of dealers  that have undertaken  to make a  market in the  security,
(iv) the number of other potential purchasers and (v) the nature of the security
and  how trading is  effected (e.g., the  time needed to  sell the security, how
offers are solicited and  the mechanics of transfer).  The Manager monitors  the
liquidity of securities held by each Underlying Theme Portfolio and periodically
reports  such determinations to the applicable  Board. The Manager believes that
carefully selected investments in joint ventures, cooperatives, partnerships and
state enterprises that are  illiquid (collectively, "Special Situations")  could
enable   an  Underlying   Theme  Portfolio   to  achieve   capital  appreciation
substantially exceeding the  appreciation it would  realize if it  did not  make
such  investments. However, in  order to attempt to  limit investment risk, each
Underlying Theme Portfolio will invest  no more than 5%  of its total assets  in
Special Situations.
 
FOREIGN SECURITIES
    POLITICAL,  SOCIAL AND ECONOMIC  RISKS. Investing in  securities of non-U.S.
companies may entail additional risks due to the potential political, social and
economic instability  of  certain  countries and  the  risks  of  expropriation,
nationalization,  confiscation  or  the imposition  of  restrictions  on foreign
investment convertibility of currencies into U.S. dollars and on repatriation of
capital invested. In the event  of such expropriation, nationalization or  other
confiscation by any country, an Underlying Theme Portfolio could lose its entire
investment in any such country.
 
    RELIGIOUS,  POLITICAL AND ETHNIC INSTABILITY.  Certain countries in which an
Underlying Theme  Portfolio may  invest may  have groups  that advocate  radical
religious  or  revolutionary philosophies  or  support ethnic  independence. Any
disturbance on  the part  of  such individuals  could  carry the  potential  for
widespread  destruction  or confiscation  of property  owned by  individuals and
entities foreign to such country and could cause the loss of an Underlying Theme
Portfolio's investment in  those countries.  Instability may  also result  from,
among  other things,  (i) authoritarian  governments or  military involvement in
political and economic decision-making, including changes in government  through
extra-constitutional  means,  (ii) popular  unrest  associated with  demands for
improved political, economic and social conditions; and (iii) hostile  relations
with  neighboring  or  other  countries.  Such  political,  social  and economic
instability could disrupt the principal financial markets in which an Underlying
Theme Portfolio invests and adversely affect the value of its assets.
 
    FOREIGN  INVESTMENT  RESTRICTIONS.  Certain  countries  prohibit  or  impose
substantial  restrictions on investments in  their capital markets, particularly
their equity markets, by foreign entities such as an Underlying Theme Portfolio.
These restrictions or  controls may at  times limit or  preclude investments  in
certain securities and may increase the cost and expenses of an Underlying Theme
Portfolio.  For example,  certain countries require  prior governmental approval
before investments by foreign  persons may be  made or may  limit the amount  of
investment by foreign persons in a particular company or limit the investment by
foreign  persons to only  a specific class  of securities of  a company that may
have less  advantageous  terms than  securities  of the  company  available  for
purchase  by nationals. Moreover, the national policies of certain countries may
restrict investment opportunities in issuers  or industries deemed sensitive  to
national  interests. In  addition, some countries  require governmental approval
for the repatriation of investment income, capital or the proceeds of securities
sales by  foreign investors.  In addition,  if  there is  a deterioration  in  a
country's  balance  of  payments or  for  other  reasons, a  country  may impose
restrictions  on  foreign  capital  remittances  abroad.  An  Underlying   Theme
Portfolio  could be adversely affected by delays  in, or a refusal to grant, any
required governmental approval for repatriation,  as well as by the  application
to it of other restrictions on investments.
 
    NON-UNIFORM CORPORATE DISCLOSURE STANDARDS AND GOVERNMENTAL
REGULATION.  Foreign companies are subject to accounting, auditing and financial
standards and requirements that differ, in some cases significantly, from  those
applicable to U.S. companies. In particular, the assets, liabilities and profits
appearing  on the  financial statements  of such a  company may  not reflect its
financial position or results of operations  in the way they would be  reflected
had  such financial statements  been prepared in  accordance with U.S. generally
accepted accounting  principles.  Most of  the  foreign securities  held  by  an
Underlying  Theme Portfolio will not be registered with the SEC or regulators of
any foreign  country, nor  will the  issuers  thereof be  subject to  the  SEC's
reporting   requirements.  Thus,  there  will   be  less  available  information
concerning most  foreign  issuers of  securities  held by  an  Underlying  Theme
Portfolio  than is  available concerning  U.S. issuers.  In instances  where the
financial statements  of an  issuer are  not deemed  to reflect  accurately  the
financial situation of the issuer, the
 
                  Statement of Additional Information Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Manager  will take appropriate steps to  evaluate the proposed investment, which
may include on-site inspection of the issuer, interviews with its management and
consultations  with  accountants,  bankers  and  other  specialists.  There   is
substantially  less publicly available information  about foreign companies than
there are reports and ratings published about U.S. companies. In addition, where
public information is available, it may  be less reliable than such  information
regarding  U.S.  issuers. Issuers  of  securities in  foreign  jurisdictions are
generally not subject to the same degree of regulation as are U.S. issuers  with
respect  to such matters as restrictions on market manipulation, insider trading
rules, shareholder proxy requirements and timely disclosure of information.
 
    CURRENCY FLUCTUATIONS. Because each Underlying Theme Portfolio, under normal
circumstances, will invest  a substantial  portion of  its total  assets in  the
securities  of foreign issuers  that are denominated  in foreign currencies, the
strength or weakness  of the U.S.  dollar against such  foreign currencies  will
account  for part of  an Underlying Theme  Portfolio's investment performance. A
decline in the  value of any  particular currency against  the U.S. dollar  will
cause  a decline  in the  U.S. dollar value  of an  Underlying Theme Portfolio's
holdings of securities  and cash  denominated in that  currency and,  therefore,
will  cause an overall  decline in its  and its corresponding  Feeder Fund's net
asset value (as  applicable) and  any net  investment income  and capital  gains
derived  from  such  securities  to  be  distributed  in  U.S.  dollars  to  the
shareholders thereof. Moreover, if the value of the foreign currencies in  which
an  Underlying Theme  Portfolio receives its  income falls relative  to the U.S.
dollar between  receipt of  the  income and  the  making of  distributions,  the
Underlying  Theme Portfolio  may be required  to liquidate securities  if it has
insufficient cash in U.S. dollars to meet distribution requirements.
 
The rate of exchange between the U.S. dollar and other currencies is  determined
by  several factors, including the supply  and demand for particular currencies,
central bank efforts to support particular currencies, the relative movement  of
interest  rates, and pace  of business activity  in the other  countries and the
United States, and other economic  and financial conditions affecting the  world
economy.
 
Although  each Underlying  Theme Portfolio values  its assets daily  in terms of
U.S. dollars, the  Underlying Theme Portfolios  do not intend  to convert  their
holdings  of  foreign  currencies  into  U.S. dollars  on  a  daily  basis. Each
Underlying Theme Portfolio will do so,  from time to time, and investors  should
be  aware of the costs of currency conversion. Although foreign exchange dealers
do not  charge a  fee for  conversion, they  do realize  a profit  based on  the
difference  ("spread") between  the prices  at which  they buy  and sell various
currencies. Thus, a dealer may offer to sell a foreign currency to an Underlying
Theme Portfolio at one rate, while offering a lesser rate of exchange should  an
Underlying Theme Portfolio desire to sell that currency to the dealer.
 
    ADVERSE  MARKET CHARACTERISTICS. Securities  of many foreign  issuers may be
less liquid and their  prices more volatile than  securities of comparable  U.S.
issuers.  In  addition, foreign  securities  markets and  brokers  generally are
subject to  less governmental  supervision  and regulation  than in  the  United
States,  and  foreign  securities  transactions  usually  are  subject  to fixed
commissions, which  generally are  higher than  negotiated commissions  on  U.S.
transactions.  In addition,  foreign securities  transactions may  be subject to
difficulties associated  with the  settlement of  such transactions.  Delays  in
settlement  could result in temporary periods when assets of an Underlying Theme
Portfolio are uninvested and  no return is earned  thereon. The inability of  an
Underlying Theme Portfolio to make intended security purchases due to settlement
problems  could cause it to  miss attractive investment opportunities. Inability
to dispose  of a  portfolio security  due to  settlement problems  either  could
result  in losses to an Underlying Theme Portfolio due to subsequent declines in
value of  the portfolio  security or,  if that  Underlying Theme  Portfolio  has
entered into a contract to sell the security, could result in possible liability
to  the purchaser. The Manager will  consider such difficulties when determining
the allocation of an Underlying  Theme Portfolio's assets, although the  Manager
does  not believe that such difficulties will  have a material adverse effect on
an Underlying Theme Portfolio's portfolio trading activities.
 
Each Underlying Theme Portfolio  may use foreign  custodians, which may  involve
risks  in addition to  those related to  its use of  U.S. custodians. Such risks
include uncertainties relating  to (1)  determining and  monitoring the  foreign
custodian's   financial  strength,  reputation  and  standing,  (2)  maintaining
appropriate safeguards concerning an  Underlying Theme Portfolio's  investments,
and  (3) possible difficulties in obtaining and enforcing judgments against such
custodians.
 
    WITHHOLDING TAXES. Each Underlying  Theme Portfolio's net investment  income
from  securities of foreign issuers  may be subject to  withholding taxes by the
foreign issuer's country, thereby reducing  that income or delaying the  receipt
of income when those taxes may be recaptured. See "Taxes."
 
    CONCENTRATION.  To  the  extent  an  Underlying  Theme  Portfolio  invests a
significant portion  of  its  assets  in securities  of  issuers  located  in  a
particular  country or region of  the world, it may  be subject to greater risks
and may  experience  greater  volatility  than  a  fund  that  is  more  broadly
diversified geographically.

    SPECIAL  CONSIDERATIONS AFFECTING WESTERN  EUROPEAN COUNTRIES. The countries
that are members of the European Economic Community ("Common Market")  (Belgium,
Denmark,  France,  Germany,  Greece,  Ireland,  Italy,  Luxembourg, Netherlands,
Portugal, Spain, and the United  Kingdom) eliminated certain import tariffs  and
quotas  and  other trade  barriers with  respect  to one  another over  the past
several years. The Manager  believes that this  deregulation should improve  the
prospects  for economic growth  in many Western  European countries. Among other
things, the  deregulation could  enable companies  domiciled in  one country  to
avail  themselves of lower labor costs existing in other countries. In addition,
this deregulation could benefit  companies domiciled in  one country by  opening
additional  markets  for their  goods and  services  in other  countries. Since,
however, it is not clear  what the exact form or  effect of these Common  Market
reforms  will be on business in Western  Europe, it is impossible to predict the
long-term impact of the implementation of these programs on the securities owned
by an Underlying Theme Portfolio.
 
    SPECIAL   CONSIDERATIONS    AFFECTING    RUSSIA   AND    EASTERN    EUROPEAN
COUNTRIES.  Investing in Russia  and Eastern European  countries involves a high
degree  of  risk  and  special  considerations  not  typically  associated  with
investing  in  the  U.S.  securities markets  and  should  be  considered highly
speculative. Such risks include the following: (1) delays in settling  portfolio
transactions  and risk of loss  arising out of the  system of share registration
and custody; (2) the risk  that it may be impossible  or more difficult than  in
other  countries  to  obtain and/or  enforce  a judgment;  (3)  pervasiveness of
corruption and  crime  in  the  economic  system;  (4)  currency  exchange  rate
volatility  and the lack  of available currency  hedging instruments; (5) higher
rates of inflation (including the risk of social unrest associated with  periods
of  hyper-inflation) and high  unemployment; (6) controls  on foreign investment
and  local   practices  disfavoring   foreign  investors   and  limitations   on
repatriation of invested capital, profits and dividends, and on a fund's ability
to  exchange local  currencies for U.S.  dollars; (7)  political instability and
social unrest and  violence; (8)  the risk that  the governments  of Russia  and
Eastern  European countries may  decide not to continue  to support the economic
reform programs  implemented  recently  and  could  follow  radically  different
political  and/or  economic policies  to the  detriment of  investors, including
non-market-oriented policies such as  the support of  certain industries at  the
expense  of other  sectors or  investors, or a  return to  the centrally planned
economy that existed when such countries had a communist form of government; (9)
the financial condition of companies in these countries, including large amounts
of inter-company debt which  may create a payments  crisis on a national  scale;
(10)  dependency on  exports and  the corresponding  importance of international
trade; (11) the risk that the tax system in these countries will not be reformed
to prevent inconsistent,  retroactive and/or exorbitant  taxation; and (12)  the
underdeveloped nature of the securities markets.
 
    SPECIAL CONSIDERATIONS AFFECTING JAPAN. Japan's economic growth has declined
significantly  since 1990. The general government position has deteriorated as a
result of weakening economic  growth and stimulative  measures taken to  support
economic  activity and to  restore financial stability.  Although the decline in
interest  rates  and  fiscal  stimulation   packages  have  helped  to   contain
recessionary  forces, uncertainties remain. Japan is also heavily dependent upon
international trade, so its  economy is especially  sensitive to trade  barriers
and  disputes.  Japan has  had difficult  relations  with its  trading partners,
particularly the United States, where the trade imbalance is the greatest. It is
possible that  trade sanctions  and other  protectionist measures  could  impact
Japan adversely in both the short and the long term.
 
The  common  stocks  of many  Japanese  companies trade  at  high price-earnings
ratios. Differences  in accounting  methods  make it  difficult to  compare  the
earnings  of  Japanese companies  with those  of  companies in  other countries,
especially in the  United States. In  general, however, reported  net income  in
Japan  is  understated relative  to U.S.  accounting standards  and this  is one
reason why price-earnings ratios of the stocks of Japanese companies have tended
historically to be  higher than  those for  U.S. stocks.  In addition,  Japanese
companies  have  tended to  have  higher growth  rates  than U.S.  companies and
Japanese interest rates  have generally been  lower than in  the United  States,
both   factors  which  tend  to  result  in  lower  discount  rates  and  higher
price-earnings ratios in Japan than in the United States.
 
The Japanese securities  markets are  less regulated  than those  in the  United
States. Evidence has emerged from time to time of distortion of market prices to
serve  political or other purposes. Shareholders'  rights are not always equally
enforced. In addition, Japan's banking  industry is undergoing problems  related
to bad loans and declining values in real estate.
 
    SPECIAL  CONSIDERATIONS AFFECTING  PACIFIC REGION COUNTRIES.  Certain of the
risks associated with international  investments are heightened for  investments
in  Pacific region  countries. For  example, some  of the  currencies of Pacific
region countries  have  experienced steady  devaluations  relative to  the  U.S.
dollar,  and major  adjustments have been  made periodically in  certain of such
currencies. Certain countries, such as India, face serious exchange constraints.
Jurisdictional disputes  also exist  between  South Korea  and North  Korea.  In
addition,  the  Underlying  Theme  Portfolios may  invest  in  Hong  Kong, which
reverted to Chinese administration on July 1, 1997. Investments in Hong Kong may
be subject to expropriation, nationalization  or confiscation, in which case  an
Underlying   Theme  Portfolio   could  lose   its  entire   investment  in  Hong
 
                  Statement of Additional Information Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Kong. In addition, the reversion of Hong Kong also presents a risk that the Hong
Kong dollar will be devalued and a risk of possible loss of investor  confidence
in Hong Kong's currency, stock market and assets.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  LATIN  AMERICAN  COUNTRIES.  Most  Latin
American countries have experienced substantial,  and in some periods  extremely
high,  rates of  inflation for many  years. Inflation and  rapid fluctuations in
inflation rates have had and may continue  to have very negative effects on  the
economies  and securities markets  of certain Latin  American countries. Certain
Latin American countries are also among the largest debtors to commercial  banks
and foreign governments. At times certain Latin American countries have declared
moratoria  on  the payment  of principal  and/or interest  on external  debt. In
addition, certain  Latin  American  securities  markets  have  experienced  high
volatility in recent years.
 
Latin  American countries may  also close certain sectors  of their economies to
equity investments  by foreigners.  Further  due to  the absence  of  securities
markets  and  publicly  owned corporations  and  due to  restrictions  on direct
investment by foreign entities,  investments may only be  made in certain  Latin
American   countries  solely   or  primarily   through  governmentally  approved
investment vehicles or companies.
 
Certain Latin American countries may have managed currencies that are maintained
at artificial levels to the U.S. dollar rather than at levels determined by  the
market.  This type  of system can  lead to  sudden and large  adjustments in the
currency which, in turn,  can have a disruptive  and negative effect on  foreign
investors.  For example, in late  1994, the value of  the Mexican peso lost more
than one-third of its value relative to the U.S. dollar.
 
    SPECIAL  CONSIDERATIONS  AFFECTING  EMERGING   MARKETS.  Investing  in   the
securities of companies in emerging markets may entail special risks relating to
potential  political and  economic instability  and the  risks of expropriation,
nationalization, confiscation  or  the  imposition of  restrictions  on  foreign
investment,  convertibility of currencies into  U.S. dollars and on repatriation
of capital  invested. In  the event  of such  expropriation, nationalization  or
other  confiscation by any country, an Underlying Theme Portfolio could lose its
entire investment in any such country.
 
Emerging securities  markets are  substantially  smaller, less  developed,  less
liquid  and more volatile than the major securities markets. The limited size of
emerging securities markets and limited trading value in issuers compared to the
volume of  trading in  U.S. securities  could  cause prices  to be  erratic  for
reasons  apart  from factors  that  affect the  quality  of the  securities. For
example, limited market size may cause prices to be unduly influenced by traders
who control  large  positions.  Adverse publicity  and  investors'  perceptions,
whether  or  not  based on  fundamental  analysis,  may decrease  the  value and
liquidity of portfolio  securities, especially  in these  markets. In  addition,
securities traded in certain emerging markets may be subject to risks due to the
inexperience  of financial intermediaries, a lack of modern technology, the lack
of a sufficient capital base to expand business operations, and the  possibility
of permanent or temporary termination of trading.
 
Settlement  mechanisms in emerging securities markets  may be less efficient and
reliable than in more developed markets.  In such emerging securities there  may
be share registration and delivery delays or failures.
 
Many emerging market countries have experienced substantial, and in some periods
extremely  high,  rates  of  inflation  for  many  years.  Inflation  and  rapid
fluctuations in inflation rates and corresponding currency devaluations have had
and may  continue to  have  negative effects  on  the economies  and  securities
markets of certain emerging market countries.
 
    PRIVATIZATIONS.  The governments of some foreign countries have been engaged
in programs  of selling  part or  all of  their stakes  in government  owned  or
controlled   enterprises   ("privatizations").   The   Manager   believes   that
privatizations may offer opportunities for significant capital appreciation  and
intends to invest assets of the Underlying Theme Portfolios in privatizations in
appropriate  circumstances. In certain foreign countries, the ability of foreign
entities  such   as  the   Underlying  Theme   Portfolios  to   participate   in
privatizations may be limited by local law, or the terms on which the Underlying
Theme  Portfolios may be permitted to  participate may be less advantageous than
those for local investors.  There can be no  assurance that foreign  governments
will  continue to sell companies  currently owned or controlled  by them or that
privatization programs will be successful.

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

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

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

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

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

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

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

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

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

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

                               INVESTMENT RESULTS
 
- --------------------------------------------------------------------------------
 
STANDARDIZED RETURNS
The  Fund's "Standardized Returns," as referred to in the Prospectus (see "Other
Information --  Performance  Information"  in  the  Prospectus),  is  calculated
separately  for Class  A, Class B  and Class C  shares of the  Fund, as follows:
Standardized Return (average annual total return ("T")) is computed by using the
ending redeeming value ("ERV")  of a hypothetical  initial investment of  $1,000
("P")  over  a period  of  years ("n")  according  to the  following  formula as
required by the SEC: P(1+T) =  ERV. The following assumptions will be  reflected
in  computations made in accordance  with this formula: (1)  for Class A shares,
deduction of  the  maximum  sales  charge  of  4.75%  from  the  $1,000  initial
investment;  (2)  for Class  B shares,  deduction  of the  applicable contingent
deferred sales charge imposed  on a redemption  of Class B  shares held for  the
period; (3) reinvestment of dividends and other distributions at net asset value
on  the reinvestment date determined by the Trust's Board of Trustees; and (4) a
complete redemption at the end of any period illustrated.
 
NON-STANDARDIZED RETURNS
In  addition   to  Standardized   Returns,  the   Fund  also   may  include   in
advertisements,  sales  literature and  shareholder  reports other  total return
performance  data  ("Non-Standardized   Return").  Non-Standardized  Return   is
calculated  separately for Class A,  Class B and Class C  shares of the Fund and
may be calculated according to several different formulas.
 
                  Statement of Additional Information Page 37
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
Non-Standardized Returns may be  quoted for the same  or different time  periods
for  which Standardized Returns are quoted.  Non-Standardized Returns may or may
not take sales charges into account; performance data calculated without  taking
the  effect of sales charges into account will be higher than data including the
effect of such charges.
 
Average annual Non-Standardized  Return ("T")  is computed by  using the  ending
redeeming  value ("ERV")  of a hypothetical  initial investment  of $1,000 ("P")
over a period of years ("n") according  to the following formula as required  by
the  SEC:  P(1+T)  =  ERV.  The  following  assumptions  will  be  reflected  in
computations made in  accordance with this  formula: (1) no  deduction of  sales
charges;  (2) reinvestment  of dividends  and other  distributions at  net asset
value on  the reinvestment  date determined  by the  Board; and  (3) a  complete
redemption at the end of any period illustrated.
 
The  Fund's investment results will vary from time to time depending upon market
conditions, the composition of each Underlying Theme Portfolio's portfolio,  and
operating  expenses of the Fund,  so that current or  past yield or total return
should not be considered  representative of what an  investment in the Fund  may
earn in any future period. These factors and possible differences in the methods
used  in calculating investment results should  be considered when comparing the
Fund's investment results  with those published  for other investment  companies
and  other investment  vehicles. The  Fund's results  also should  be considered
relative to  the  risks associated  with  the Fund's  investment  objective  and
policies.
 
IMPORTANT POINTS TO NOTE ABOUT DATA RELATING TO WORLD EQUITY AND BOND MARKETS
The Fund and GT Global may from time to time in advertisements, sales literature
and  reports furnished to  present or prospective  shareholders compare the Fund
with the following, among others:
 
        (1) The Consumer Price Index ("CPI"), which is a measure of the  average
    change  in prices over time  in a fixed market  basket of goods and services
    (e.g., food,  clothing, shelter,  fuels, transportation  fares, charges  for
    doctors' and dentists' services, prescription medicines, and other goods and
    services  that people  buy for day-to-day  living). There  is inflation risk
    which does not affect a security's value but its purchasing power, i.e.  the
    risk of changing price levels in the economy that affects security prices or
    the price of goods and services.
 
        (2)  Data  and  mutual fund  rankings  published or  prepared  by Lipper
    Analytical  Data  Services,  Inc.  ("Lipper"),  CDA/Wiesenberger  Investment
    Companies  Service ("CDA/Wiesenberger"),  Morningstar, Inc.,  Micropal, Inc.
    and/or other  companies that  rank and/or  compare mutual  funds by  overall
    performance,  investment  objectives,  assets,  expense  levels,  periods of
    existence and/or other factors. In this  regard the Fund may be compared  to
    its  "peer group" as defined by Lipper, CDA/Wiesenberger, Morningstar and/or
    other firms, as applicable, or to  specific funds or groups of funds  within
    or  outside of such peer group. Lipper generally ranks funds on the basis of
    total return,  assuming reinvestment  of distributions,  but does  not  take
    sales charges or redemption fees into consideration, and is prepared without
    regard  to tax  consequences. In addition  to the mutual  fund rankings, the
    Fund's performance  may  be  compared to  mutual  fund  performance  indices
    prepared  by Lipper. Morningstar  is a mutual fund  rating service that also
    rates mutual funds  on the basis  of risk-adjusted performance.  Morningstar
    ratings are calculated from a fund's three, five and ten year average annual
    returns  with appropriate  fee adjustments and  a risk  factor that reflects
    fund performance  relative to  the three-month  U.S. Treasury  bill  monthly
    returns.  Ten percent  of the funds  in an investment  category receive five
    stars and 22.5% receive four stars.  The ratings are subject to change  each
    month.
 
        (3)  Bear  Stearns Foreign  Bond  Index, which  provides  simple average
    returns for individual countries and gross national product ("GNP") weighted
    index, beginning in 1975.  The returns are broken  down by local market  and
    currency.
 
        (4)  Ibbotson  Associates  International Bond  Index,  which  provides a
    detailed breakdown of local market and currency returns since 1960.
 
        (5) Standard & Poor's 500 Composite Stock Price Index, which is a widely
    recognized index  composed of  the  capitalization-weighted average  of  the
    price of 500 of the largest publicly traded stocks in the United States.
 
        (6) Dow Jones Industrial Average.
 
        (7) CNBC/Financial News Composite Index.
 
        (8) Morgan Stanley Capital International World Indices, including, among
    others, the Morgan Stanley Capital International Europe, Australia, Far East
    Index  ("EAFE Index").  The EAFE  index is an  unmanaged index  of more than
    1,000 companies in Europe, Australia and the Far East.
 
        (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.

    savings deposits, including longer-term certificates. Savings accounts offer
    a guaranteed rate  of return on  principal, but no  opportunity for  capital
    growth.  During a  portion of  the period,  the maximum  rates paid  on some
    savings deposits were fixed by law.
 
Indices, economic and  financial data  prepared by the  research departments  of
various   financial  organizations,  such  as  Salomon  Brothers,  Inc.,  Lehman

Corporation,  J.P. Morgan, Morgan Stanley,  Smith Barney Shearson, S.G. Warburg,
Jardine Flemming,  The Bank  for  International Settlements,  Asian  Development
Bank,  Bloomberg,  L.P.,  and  Ibbotson  Associates, may  be  used,  as  well as
information reported by the Federal Reserve and the respective central banks  of
various  nations. In addition,  GT Global may  use performance rankings, ratings
and  commentary  reported  periodically  in  national  financial   publications,
including  Money Magazine,  Mutual Fund  Magazine, Smart  Money, Global Finance,
EuroMoney, Financial World, Forbes, Fortune,  Business Week, Latin Finance,  the
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 plans and programs  may produce returns superior to  comparable
non-retirement  investments. For example, a $10,000 investment earning a taxable
return of 10% annually would have an after-tax value of $17,976 after ten years,
assuming tax  was  deducted from  the  return each  year  at a  39.6%  rate.  An
equivalent  tax-deferred  investment would  have an  after-tax value  of $19,626
after ten years, assuming  tax was deducted  at a 39.6%  rate from the  deferred
earnings   at  the   end  of  the   ten-year  period.  In   sales  material  and
advertisements, the  Fund  may  also  discuss  these  plans  and  programs.  See
"Information Relating to Sales and Redemptions -- Individual Retirement Accounts
("IRAs") and Other Tax-Deferred Plans."
 
GT  Global may from time to time  in its sales materials and advertising discuss
the risks inherent in investing. The  major types of investment risk are  market
risk,  industry  risk,  credit  risk, interest  rate  risk,  liquidity  risk and
inflation risk. Risk represents the possibility that you may lose some or all of
your investment over a period of time. A basic tenet of investing is the greater
the potential reward, the greater the risk.
 
From time to time, the Fund and GT Global will quote data regarding  industries,
companies,  individual countries,  regions, world stock  exchanges, and economic

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

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

INFORMATION ABOUT THE GLOBAL HEALTH CARE INDUSTRIES
The  Fund and  the Manager believe  that certain market  and demographic factors
merit  an  investor's  consideration  when  making  a  health  care  investment.
Worldwide   standards  of  living  and  life  expectancy  have  increased  at  a
substantial rate. Chancellor  LGT Asset  Management, Inc.  (the "Manager"),  the
investment  adviser to  the GT Global  Mutual Funds, expects  this growth, which
works to the general benefit of the global health care industry, to continue  at
a  roughly comparable rate in the future, although no assurances can be given in
this regard.  Moreover,  according to  the  Manager, the  health  care  industry
historically  has proven to be a relatively non-cyclical industry that continues
to provide goods and services to the  public in periods of economic weakness  as
well as economic strength.
 
The  Manager  believes  that the  anticipated  increase in  the  world's elderly
population could  increase demand  for health  care products  and services.  For
example,  according to  data compiled  by the  Manager, in  Japan the  number of
people age 65  and older  is expected to  grow over  100% by the  year 2025;  in
Germany, France and the U.S., the same age group should grow 40%. Similarly, the
U.S.  Census Bureau predicts the  number of Americans 85  and older to double in
the next  30 years.  From  time to  time,  the Fund  and  GT Global  will  quote
information   including,  but  not  limited  to,  international  data  regarding
populations,  birth  rates,  mortality  rates,  life  expectancy,  health   care
expenditures,  and gross domestic  product vs. life  expectancy. The information
quoted has not been independently verified by the Fund or GT Global and will  be
based on data that is believed to be reliable and accurate.
 
TELECOMMUNICATIONS FUND
From  time to time the Fund and  GT Global will quote information including data
regarding:
 
    / / Increased usage  of  new  technologies  such as,  but  not  limited  to,
        cellular   and  wireless  communications  in  emerging  and  established
        countries around the world
 
    / / Supply and demand of telephone equipment and services
 
    / / Regulatory environment of telecommunications industries
 
    / / Revenue, price and usage of telecommunications products and services
 
    / / Privatization and/or deregulation of telecommunications companies
 
The information quoted  has not been  independently verified by  the Fund or  GT
Global  and will be based  on data provided that is  believed to be reliable and
accurate from sources including the following:
 
    / / Salomon Brothers World Equity  Telecommunications Index, which  includes
        stock  market data about the  telecommunications industry in established
        and developing markets
 
    / / OECD  and  other  publications  from   its  subsidiaries  such  as   the
        International Telecommunications Union

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

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

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

<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
        CC -- Typically  applied to  debt subordinated  to senior  debt that  is
    assigned an actual or implied "CCC" rating.
 
        C  --  Typically applied  to debt  subordinated to  senior debt  that is
    assigned an actual or implied "CCC-" debt rating. The "C" rating may be used
    to cover a situation  where a bankruptcy petition  has been filed, but  debt
    service payments are continued.
 
        C1 -- Reserved for income bonds on which no interest is being paid.
 
        D -- In payment default. The "D" category is used when interest payments
    or  principal payments are not  made on the date  due even if the applicable
    grace period has not expired, unless S&P believes that such payments will be
    made during such grace period. This rating will also be used upon the filing
    of a bankruptcy petition if debt service payments are jeopardized.
 
PLUS (+) OR MINUS  (-): The ratings from  "AA" to "CCC" may  be modified by  the
addition  of a  plus or minus  sign to  show relative standing  within the major
rating categories.
 
NR:  Indicates  that  no  public  rating  has  been  requested,  that  there  is
insufficient  information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

To the Shareholders of GT Global New Dimension Fund and

changes in net assets, and the financial highlights for the period from

financial statements and the financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and the financial highlights referred
to above present fairly, in all material respects, the financial position of GT
Global New Dimension Fund as of December 31, 1997, the results of its
operations, the changes in its net assets, and the financial highlights for the

                              FINANCIAL STATEMENTS
                               December 31, 1997
 
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
GT Global New Dimension Fund ("Fund") is a diversified series of GT Global
Series Trust (the "Trust"). The Trust is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end management investment company. The Fund invests
substantially all of its assets in Advisor Class 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").
 
The Fund offers Class A, Class B and Advisor Class shares, each of which has
equal rights as to assets and voting privileges. Class A and Class B each has
exclusive voting rights with respect to its distribution plan. Investment
income, realized and unrealized capital gains and losses of the Fund are
allocated on a pro rata basis to each Class based on the relative net assets of
each Class to the total net assets of the Fund. Each Class of shares differs in
its respective service and distribution expenses. Beginning January 1, 1998, the
Fund will also offer Class C shares.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies in conformity with generally accepted accounting
principles consistently followed by the Funds in the preparation of the
financial statements.
 
(A) PORTFOLIO VALUATION
The Fund calculates the net asset value of and completes orders to purchase,
exchange or repurchase Fund shares on each business day, with the exception of
those days on which the New York Stock Exchange is closed.
 
Investments in the Underlying Funds are valued at the closing net asset value
per Advisor Class share of each Underlying Fund on the day of valuation.
Short-term investments with a maturity of 60 days or less are valued at
amortized cost.
 
(B) REPURCHASE AGREEMENTS
With respect to repurchase agreements entered into by the Fund, it is the Fund's
policy to always receive, as collateral, United States government securities or
other high quality debt securities of which the value, including accrued
interest, is at least equal to the amount to be repaid to the Fund under each
agreement at its maturity.
 
(C) TAXES
It is the policy of the Fund to meet the requirements for qualification as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended ("Code"). It is also the intention of the Fund to make distributions
sufficient to avoid imposition of any excise tax under Section 4982 of the Code.
Therefore, no provision has been made for Federal taxes on income, capital
gains, or unrealized appreciation of securities held, and excise tax on income
and capital gains.
 
(D) DISTRIBUTIONS TO SHAREHOLDERS
Distributions to shareholders are recorded by the Fund on the ex-date. Income
and capital gain distributions are determined in accordance with Federal income
tax regulations which may differ from generally accepted accounting principles.
These differences are primarily due to differing treatments of income and gains
on various investment securities held by the Fund and timing differences.
 
(E) LINE OF CREDIT
The Fund, along with certain other funds ("GT Funds") advised and/ or
administered by the Manager, has a line of credit with BankBoston and State
Street Bank & Trust Company. The arrangements with the banks allow the Fund and
the GT Funds to borrow an aggregate maximum amount of $250,000,000. The Fund is
limited to borrowing up to 33 1/3% of the value of the Fund's total assets. For
the period ended December 31, 1997, the Fund had no outstanding loan balance.
 
2. RELATED PARTIES
Chancellor LGT Asset Management, Inc. is the Fund's investment manager and
administrator. The Manager is also the pricing and accounting agent for the
Fund. The Manager will initially assume all costs of the Fund's operation,
except for service and distribution fees as 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. Subject to receipt
of a pending exemptive order from the Securities and Exchange Commission, the
Trust, on behalf of the Fund, will enter into a Special Servicing Agreement
("Agreement") with the Underlying Theme Funds, the Manager and GT Global
Investor Services, Inc., the transfer agent. If the Board of Trustees of the
Underlying Theme Funds makes certain findings, each Underlying Theme Fund will
pay certain nondistribution-related expenses of the Fund to the extent such
expenses are less than the estimated savings to the Underlying Theme Funds from
the operation of the Fund. The Manager and GT Global also voluntarily have
undertaken to limit the Underlying Theme Fund's expenses (exclusive of brokerage
commissions, taxes, interest, and extraordinary expenses) to the maximum annual
rate of 1.50% of the average daily net assets of the Underlying Theme Fund's
Advisor Class shares.

                          GT GLOBAL NEW DIMENSION FUND
 
GT Global, Inc. ("GT Global"), an affiliate of the Manager, serves as the Fund's
distributor. The Fund offers Class A, Class B and Advisor Class shares for
purchase and will offer Class C shares for purchase beginning January 1, 1998.
 
Class A shares are subject to initial sales charges imposed at the time of
purchase, in accordance with the schedule included in the Fund's current
prospectus. GT Global collects the sales charges imposed on sales of Class A
shares, and reallows a portion of such charges to dealers through which the
sales are made. For the period from September 15, 1997 (commencement of
operations) to December 31, 1997, GT Global retained $6,174 of such sales
charges. Purchases of Class A shares exceeding $500,000 may be subject to a
contingent deferred sales charge ("CDSC") upon redemption, in accordance with
the Fund's current prospectus. GT Global collected no CDSCs for the period from
September 15, 1997 (commencement of operations) to December 31, 1997. GT Global
also makes ongoing shareholder servicing and trail commission payments to
dealers whose clients hold Class A shares.
 
Class B shares are not subject to initial sales charges. When Class B shares are
sold, GT Global from its own resources pays commissions to dealers through which
the sales are made. Certain redemptions of Class B shares made within six years
of purchase are subject to CDSCs, in accordance with the Fund's current
prospectus. For the period from September 15, 1997 (commencement of operations)
to December 31, 1997, GT Global collected CDSCs in the amount of $1,902. In
addition, GT Global makes ongoing shareholder servicing and trail commission
payments to dealers whose clients hold Class B shares.
 
Class C shares will not be subject to initial sales charges. However, certain
redemptions of Class C shares made within one year of purchase will be subject
to CDSCs. In addition, GT Global will make ongoing shareholder servicing and
trail commission payments to dealers whose clients hold Class C shares.
 
Pursuant to Rule 12b-1 under the 1940 Act, the Trust's Board of Trustees has
adopted separate distribution plans with respect to the Fund's Class A shares
("Class A Plan") and Class B shares ("Class B Plan"), pursuant to which the Fund
reimburses GT Global for a portion of its shareholder servicing and distribution
expenses. Under the 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 GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and may pay GT Global a distribution fee at
the annualized rate of up to 0.50% 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 GT Global's expenditures incurred in providing services as distributor.
All expenses for which GT Global is reimbursed under the Class A Plan will have
been incurred within one year of such reimbursement.
 
Pursuant to the Fund's Class B Plan, the Fund may pay GT Global a service fee at
the annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class B shares for GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and may pay GT Global a distribution fee at
the annualized rate of up to 0.75% of the average daily net assets of the Fund's
Class B shares for GT Global's expenditures incurred in providing services as
distributor. Expenses incurred under the Class B Plan in excess of 1.00%
annually may be carried forward for reimbursement in subsequent years as long as
that Plan continues in effect. Class C shares will also be subject to a separate
distribution plan adopted by the Trust's Board of Trustees pursuant to Rule
12b-1 under the 1940 Act.
 
GT Global Investor Services, Inc. ("GT Services"), an affiliate of the Manager
and GT Global, is the transfer agent of the Fund. For performing shareholder
servicing, reporting, and general transfer agent services, GT Services receives
an annual maintenance fee of $17.50 per account, a new account fee of $4.00 per
account, a per transaction fee of $1.75 for all transactions other than
exchanges and a per exchange fee of $2.25. GT Services is also reimbursed for
its out-of-pocket expenses for such items as postage, forms, telephone charges,
stationery and office supplies.
 
The Trust pays each of its Trustees who is not an employee, officer or director
of the Manager, GT Global or GT Services $5,000 per year plus $300 for each
meeting of the board or any committee thereof attended by the Trustee.

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

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

Assets used as cover or held in a segregated account cannot be sold while the
position in the corresponding Forward Contract, Futures Contract or option is
open, unless they are replaced with other appropriate assets. If a large portion
of an Underlying Theme Portfolio's assets is used for cover or otherwise set
aside, it could affect portfolio management or the Underlying Theme Portfolio's
ability to meet redemption requests or other current obligations.

                             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 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,
 
                  Statement of Additional Information Page 16
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
(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 foreign securities held by an
Underlying Theme Portfolio will not be registered with the SEC or regulators of
any foreign country, nor will the issuers thereof be subject to the SEC's
reporting requirements. Thus, there will be less available information
concerning most foreign issuers of securities held by an Underlying Theme
Portfolio than is available concerning U.S. issuers. In instances where the
financial statements of an issuer are not deemed to reflect accurately the
financial situation of the issuer, the 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.
 
                  Statement of Additional Information Page 17
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
    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."
 
    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
 
                  Statement of Additional Information Page 18
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 exist between South Korea and North Korea. In
addition, the Underlying Theme Portfolios may invest in Hong Kong, which
reverted to Chinese administration on July 1, 1997. Investments in Hong Kong may
be subject to expropriation, nationalization or confiscation, in which case an
Underlying Theme Portfolio could lose its entire investment in Hong 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
 
                  Statement of Additional Information Page 19
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
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 maintain short positions in connection with its use
    of financial options an futures, forward and spot currency contracts, swap
    transactions and other financial contracts or derivative instruments; or
 
        (5) Purchase securities of other investment companies, except to the
    extent permitted by the 1940 Act or under the terms of any exemptive order
    granted by the SEC and except that this limitation does not apply to
    securities received or acquired as dividends, through offers of exchange, or
    as a result of reorganization, consolidation, or merger.
 
If a percentage restriction on investment or utilization of assets is adhered to
at the time of an investment or transaction, a later change in percentage
ownership of a security or kind of securities resulting from changing market
values or a similar type of event will not be considered a violation of the
Fund's policies or restrictions.
 
Notwithstanding the forgoing investment limitations, the Fund may invest in
Underlying Theme Funds that have adopted investment limitations that may be more
or less restrictive than those listed above. As a result, the Fund may engage
indirectly in investment strategies that are prohibited under the investment
limitations listed above. The investment limitations and other investment
policies and restrictions of each Underlying Theme Fund are described in its
prospectus and statement of additional information.
 
Pursuant to Section 12(d)(1)(G) of the 1940 Act, the Fund may invest
substantially all of its assets in the Underlying Theme Funds.
 
INVESTMENT LIMITATIONS OF THE UNDERLYING THEME FUNDS AND PORTFOLIOS
FEEDER FUNDS
 
The Consumer Products and Services Fund, Financial Services Fund, Infrastructure
Fund, and Natural Resources Fund each has the following fundamental investment
policy to enable it to invest in the Global Consumer Products and Services
Portfolio, Global Financial Services Portfolio, Global Infrastructure Portfolio
and Global Natural Resources Portfolio respectively:
 
    Notwithstanding any other investment policy of the Fund, the Fund may
    invest all of its investable assets (cash, securities and receivables
    related to securities) in an open-end management investment company
    having substantially the same investment objective, policies and
    limitations as the Fund.
 
All other fundamental investment policies, and the non-fundamental investment
policies, of each Feeder Fund and its corresponding Portfolio are identical.
Therefore, although the following discusses the investment policies of each
Portfolio and Global Investment Portfolio's Board of Trustees, it applies
equally to each Feeder Fund and the Company's Board of Directors.
 
Each Portfolio has adopted the following investment limitations as fundamental
policies that (unless otherwise noted) may not be changed without a Required
Vote. Whenever a Feeder Fund is requested to vote on a change in the investment
limitations of its corresponding Portfolio, that Feeder Fund will hold a meeting
of its shareholders and will cast its votes as instructed by its shareholders.
 
No Portfolio may:
 
        (1) Buy or sell real estate (including real estate limited
    partnerships); however, each Portfolio may invest in debt securities secured
    by real estate or interests therein or issued by companies which invest in
    real estate or interests therein, including real estate investment trusts;
 
        (2) Buy or sell commodities or commodity contracts, except that each
    Portfolio may purchase and sell financial and currency futures contracts and
    options thereon, and may purchase and sell currency forward contracts,
    options on foreign currencies and may otherwise engage in other transactions
    in foreign currencies;
 
        (3) Underwrite securities of other issuers, except to the extent that
    the disposition of an investment position may technically cause it to be
    considered an underwriter as that term is defined under the 1933 Act;
 
        (4) Make loans, except that each Portfolio may purchase debt securities
    and enter into repurchase agreements and may make loans of portfolio
    securities;
 
        (5) Purchase securities on margin, provided that each Portfolio may
    obtain such short-term credits as may be necessary for the clearance of
    purchases and sales of securities; except that it may make margin deposits
    in connection with futures contracts;
 
                  Statement of Additional Information Page 22

                          GT GLOBAL NEW DIMENSION FUND
 
        (6) Borrow money except from banks not in excess of 33 1/3% of the value
    of each Portfolio's total assets, (including the amount borrowed), less all
    liabilities and indebtedness (other than the borrowing). This restriction
    shall not prevent any Portfolio from entering into reverse repurchase
    agreements, provided that reverse repurchase agreements, and any other
    transactions constituting borrowing by a Portfolio may not exceed one-third
    of that Portfolio's total assets. Transactions involving options, futures
    contracts, options on futures contracts and forward currency contracts, as
    described in its prospectus and Statement of Additional Information, and
    reflected in the Fund's Prospectus and this Statement of Additional
    Information, and collateral arrangements relating thereto will not be deemed
    to be borrowings;
 
        (7) Mortgage, pledge, or hypothecate any of its assets, provided that
    this restriction shall not apply to the transfer of securities in connection
    with any permissible borrowing or to collateral arrangements in connection
    with permissible activities; or
 
        (8) Invest in direct interests or leases in oil, gas, or other mineral
    exploration or development programs; however, each Portfolio may invest in
    the securities of companies that engage in these activities.
 
In addition, each Portfolio has adopted as a fundamental investment policy a
classification as a "diversified" fund under the 1940 Act. This means that, with
respect to 75% of a Portfolio's total assets, no more than 5% will be invested
in the securities of any one issuer, and the Portfolio will purchase no more
than 10% of the outstanding voting securities of any one issuer. This policy
cannot be changed without a Required Vote.
 
The following investment policies of each Portfolio are not fundamental policies
and may be changed by vote of Global Investment Portfolio's Board of Trustees
without shareholder approval.
 
No Portfolio may:
 
        (1) Invest in securities of an issuer if the investment would cause the
    Portfolio to own more than 10% of any class of securities of any one issuer;
 
        (2) Invest in companies for the purpose of exercising control or
    management;
 
        (3) Invest more than 15% of its net assets in illiquid securities,
    including securities that are illiquid by virtue of the absence of a readily
    available market;
 
        (4) Invest more than 5% of its total assets in securities of companies
    having, together with their predecessors, a record of less than three years
    of continuous operation;
 
        (5) Purchase or retain the securities of any issuer, if those individual
    officers and Trustees of the Portfolio, the Portfolio's investment adviser,
    or distributor, each owning beneficially more than 1/2 of 1% of the
    securities of such issuer, together own more than 5% of the securities of
    such issuer;
 
        (6) Enter into a futures contract, an option on a futures contract, or
    an option on foreign currency traded on a CFTC-regulated exchange, in each
    case other than for BONA FIDE hedging purposes (as defined by the CFTC), if
    the aggregate initial margin and premiums required to establish all of those
    positions (excluding the amount by which options are "in-the-money") exceeds
    5% of the liquidation value of the Portfolio's portfolio, after taking into
    account unrealized profits and unrealized losses on any contracts the
    Portfolio has entered into;
 
        (7) Borrow money except for temporary or emergency purposes (not for
    leveraging) in excess of 33 1/3% of the value of the Portfolio's total
    assets (while borrowings exceed 5% of the Global Infrastructure Portfolio's
    or the Global Natural Resources Portfolio's total assets, such Portfolio
    will not make any additional investments); and
 
        (8) Invest more than 10% of its total assets in shares of other
    investment companies and may not invest more than 5% of its total assets in
    any one investment company or acquire more than 3% of the outstanding voting
    securities of any one investment company.
 
Investors should refer to the Underlying Theme Funds' prospectus for further
information with respect to the investment objective of each Feeder Fund, which
may not be changed without the approval of its shareholders, and its
corresponding Portfolio's investment objective, which may be changed without the
approval of its interestholders, and other investment policies, techniques and
limitations, which may or may not be changed without interestholder approval.

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

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

    options, futures contracts and options on futures contracts;

        (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

        (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

    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;

    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,

        (4) Make loans, except that the Telecommunications Fund may purchase
    debt securities and enter into repurchase agreements and may make loans of
    portfolio securities;

    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 its prospectus and Statement of Additional
    Information, and reflected in the Fund's Prospectus and this Statement of
    Additional Information, and collateral arrangements relating thereto will
    not be deemed to be borrowings;
 
        (7) Mortgage, pledge, or hypothecate any of its assets, provided that
    this restriction shall not apply to the transfer of securities in connection
    with any permissible borrowing or to collateral arrangements in connection
    with permissible activities; or
 
        (8) Invest in direct interests or leases in oil, gas, or other mineral
    exploration or development programs; however, 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.
 
                  Statement of Additional Information Page 25
<PAGE>
                          GT GLOBAL NEW DIMENSION FUND
 
The Telecommunications Fund has the authority to invest up to 10% of its total
assets in shares of other investment companies and in real estate investment
trusts. The Telecommunications Fund may not invest more than 5% of its total
assets in any one investment company or acquire more than 3% of the outstanding
voting securities of any one investment company.
 
Investors should refer to the Underlying Theme Funds' prospectus for further
information with respect to the Telecommunications Fund's investment objective,
which may not be changed without a Required Vote, and other investment policies,
techniques and limitations, which may be changed without shareholder approval.
 
If a percentage restriction on investment or utilization of assets in an
investment policy or restriction is adhered to at the time an investment is
made, a later change in percentage ownership of a security or kind of securities
resulting from changing market values or a similar type of event will not be
considered a violation of the Underlying Theme Portfolio's investment policies
or restrictions. An Underlying Theme Portfolio may exchange securities, exercise
conversion or subscription rights, warrants or other rights to purchase common
stock or other equity securities and may hold, except to the extent limited by
the 1940 Act, any such securities so acquired without regard to the Underlying
Theme Portfolio's investment policies and restrictions. The original cost of the
securities so acquired will be included in any subsequent determination of the
Underlying Theme Portfolio's compliance with the investment percentage
limitations referred to above and in the Prospectus.

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

                            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 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.

                          GT GLOBAL NEW DIMENSION 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 at a loss, other shares of that Underlying Theme Fund (whether
pursuant to a rebalancing of the Fund's portfolio or otherwise) all or a part of
the loss will not be deductible by the Fund and instead will increase its basis
for the newly purchased shares.
 
Although an Underlying Theme Fund will be eligible to elect to "pass-through" to
its shareholders (including the Fund) the benefit of the foreign tax credit with
respect to any foreign and U.S. possessions income taxes it pays if more than
50% in the value of its total assets at the close of any taxable year consists
of securities of foreign corporations, the Fund will not qualify to pass that
benefit through to its shareholders because of its inability to satisfy that
asset test.
 
The Fund will be subject to a nondeductible 4% excise tax to the extent it fails
to distribute by the end of any calendar year substantially all of its ordinary
income for that year and capital gain net income for the one-year period ending
on October 31 of that year, plus certain other amounts.
 
TAXATION OF THE FUND'S SHAREHOLDERS
Dividends and other distributions declared by the Fund, and payable to
shareholders of record as of a date, in October, November or December of any
year will be deemed to have been paid by the Fund and received by the
shareholders on December 31 of that year if the distributions are paid by the
Fund during the following January. Accordingly, those distributions will be
taxed to shareholders for the year in which that December 31 falls.
 
A portion of the dividends from the Fund's investment company taxable income
(whether paid in cash or reinvested in additional shares) may be eligible for
the dividends-received deduction allowed to corporations. The eligible portion
may not exceed the total of the Fund's share of the aggregate dividends received
by each Underlying Theme Fund from U.S. corporations. However, dividends
received by a corporate shareholder and deducted by it pursuant to the
dividends-received deduction may be subject indirectly to the alternative
minimum tax.
 
If Fund shares are sold at a loss after being held for six months or less, the
loss will be treated as long-term, instead of short-term, capital loss to the
extent of any capital gain distributions received on those shares. Investors
also should be 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, however, to a dividend paid by the
Fund to a foreign shareholder that 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 resident alien individual for federal income tax purposes.
 
The foregoing is a general and abbreviated summary of certain federal tax
considerations affecting the Fund and its shareholders. Investors are urged to
consult their own tax advisers for more detailed information and for information
regarding any foreign, state and local taxes applicable to distributions
received from the Fund.

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

The audited financial statements of the Trust included in this Statement of
Additional Information have been examined by Coopers & Lybrand L.L.P., as stated
in their opinion appearing herein, and are included in reliance upon such
opinion given upon the authority of that firm as experts in accounting and

USE OF NAME
The Manager has granted the Trust the right to use the "GT" and "GT Global"
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
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 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.

                               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, 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 MARKETS
The Fund and GT Global may from time to time in advertisements, sales literature
and reports furnished to present or prospective shareholders compare the Fund
with the following, among others:
 
        (1) The Consumer Price Index, 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
based on data that is believed to be reliable and accurate.

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

                              FINANCIAL STATEMENTS
                               December 31, 1997
 
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
GT Global New Dimension Fund ("Fund") is a diversified series of GT Global
Series Trust (the "Trust"). The Trust is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end management investment company. The Fund invests
substantially all of its assets in Advisor Class 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").
 
The Fund offers Class A, Class B and Advisor Class shares, each of which has
equal rights as to assets and voting privileges. Class A and Class B each has
exclusive voting rights with respect to its distribution plan. Investment
income, realized and unrealized capital gains and losses of the Fund are
allocated on a pro rata basis to each Class based on the relative net assets of
each Class to the total net assets of the Fund. Each Class of shares differs in
its respective service and distribution expenses. Beginning January 1, 1998, the
Fund will also offer Class C shares.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies in conformity with generally accepted accounting
principles consistently followed by the Funds in the preparation of the
financial statements.
 
(A) PORTFOLIO VALUATION
The Fund calculates the net asset value of and completes orders to purchase,
exchange or repurchase Fund shares on each business day, with the exception of
those days on which the New York Stock Exchange is closed.
 
Investments in the Underlying Funds are valued at the closing net asset value
per Advisor Class share of each Underlying Fund on the day of valuation.
Short-term investments with a maturity of 60 days or less are valued at
amortized cost.
 
(B) REPURCHASE AGREEMENTS
With respect to repurchase agreements entered into by the Fund, it is the Fund's
policy to always receive, as collateral, United States government securities or
other high quality debt securities of which the value, including accrued
interest, is at least equal to the amount to be repaid to the Fund under each
agreement at its maturity.
 
(C) TAXES
It is the policy of the Fund to meet the requirements for qualification as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended ("Code"). It is also the intention of the Fund to make distributions
sufficient to avoid imposition of any excise tax under Section 4982 of the Code.
Therefore, no provision has been made for Federal taxes on income, capital
gains, or unrealized appreciation of securities held, and excise tax on income
and capital gains.
 
(D) DISTRIBUTIONS TO SHAREHOLDERS
Distributions to shareholders are recorded by the Fund on the ex-date. Income
and capital gain distributions are determined in accordance with Federal income
tax regulations which may differ from generally accepted accounting principles.
These differences are primarily due to differing treatments of income and gains
on various investment securities held by the Fund and timing differences.
 
(E) LINE OF CREDIT
The Fund, along with certain other funds ("GT Funds") advised and/ or
administered by the Manager, has a line of credit with BankBoston and State
Street Bank & Trust Company. The arrangements with the banks allow the Fund and
the GT Funds to borrow an aggregate maximum amount of $250,000,000. The Fund is
limited to borrowing up to 33 1/3% of the value of the Fund's total assets. For
the period ended December 31, 1997, the Fund had no outstanding loan balance.
 
2. RELATED PARTIES
Chancellor LGT Asset Management, Inc. is the Fund's investment manager and
administrator. The Manager is also the pricing and accounting agent for the
Fund. The Manager will initially assume all costs of the Fund's operation,
except for service and distribution fees as 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. Subject to receipt
of a pending exemptive order from the Securities and Exchange Commission, the
Trust, on behalf of the Fund, will enter into a Special Servicing Agreement
("Agreement") with the Underlying Theme Funds, the Manager and GT Global
Investor Services, Inc., the transfer agent. If the Board of Trustees of the
Underlying Theme Funds makes certain findings, each Underlying Theme Fund will
pay certain nondistribution-related expenses of the Fund to the extent such
expenses are less than the estimated savings to the Underlying Theme Funds from
the operation of the Fund. The Manager and GT Global also voluntarily have
undertaken to limit the Underlying Theme Fund's expenses (exclusive of brokerage

GT Global, Inc. ("GT Global"), an affiliate of the Manager, serves as the Fund's
distributor. The Fund offers Class A, Class B and Advisor Class shares for
purchase and will offer Class C shares for purchase beginning January 1, 1998.
 
Class A shares are subject to initial sales charges imposed at the time of
purchase, in accordance with the schedule included in the Fund's current
prospectus. GT Global collects the sales charges imposed on sales of Class A
shares, and reallows a portion of such charges to dealers through which the
sales are made. For the period from September 15, 1997 (commencement of
operations) to December 31, 1997, GT Global retained $6,174 of such sales
charges. Purchases of Class A shares exceeding $500,000 may be subject to a
contingent deferred sales charge ("CDSC") upon redemption, in accordance with
the Fund's current prospectus. GT Global collected no CDSCs for the period from
September 15, 1997 (commencement of operations) to December 31, 1997. GT Global
also makes ongoing shareholder servicing and trail commission payments to
dealers whose clients hold Class A shares.
 
Class B shares are not subject to initial sales charges. When Class B shares are
sold, GT Global from its own resources pays commissions to dealers through which
the sales are made. Certain redemptions of Class B shares made within six years
of purchase are subject to CDSCs, in accordance with the Fund's current
prospectus. For the period from September 15, 1997 (commencement of operations)
to December 31, 1997, GT Global collected CDSCs in the amount of $1,902. In
addition, GT Global makes ongoing shareholder servicing and trail commission
payments to dealers whose clients hold Class B shares.
 
Class C shares will not be subject to initial sales charges. However, certain
redemptions of Class C shares made within one year of purchase will be subject
to CDSCs. In addition, GT Global will make ongoing shareholder servicing and
trail commission payments to dealers whose clients hold Class C shares.
 
Pursuant to Rule 12b-1 under the 1940 Act, the Trust's Board of Trustees has
adopted separate distribution plans with respect to the Fund's Class A shares
("Class A Plan") and Class B shares ("Class B Plan"), pursuant to which the Fund
reimburses GT Global for a portion of its shareholder servicing and distribution
expenses. Under the 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 GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and may pay GT Global a distribution fee at
the annualized rate of up to 0.50% 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 GT Global's expenditures incurred in providing services as distributor.
All expenses for which GT Global is reimbursed under the Class A Plan will have
been incurred within one year of such reimbursement.
 
Pursuant to the Fund's Class B Plan, the Fund may pay GT Global a service fee at
the annualized rate of up to 0.25% of the average daily net assets of the Fund's
Class B shares for GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and may pay GT Global a distribution fee at
the annualized rate of up to 0.75% of the average daily net assets of the Fund's
Class B shares for GT Global's expenditures incurred in providing services as
distributor. Expenses incurred under the Class B Plan in excess of 1.00%
annually may be carried forward for reimbursement in subsequent years as long as
that Plan continues in effect. Class C shares will also be subject to a separate
distribution plan adopted by the Trust's Board of Trustees pursuant to Rule
12b-1 under the 1940 Act.
 
GT Global Investor Services, Inc. ("GT Services"), an affiliate of the Manager
and GT Global, is the transfer agent of the Fund. For performing shareholder
servicing, reporting, and general transfer agent services, GT Services receives
an annual maintenance fee of $17.50 per account, a new account fee of $4.00 per
account, a per transaction fee of $1.75 for all transactions other than
exchanges and a per exchange fee of $2.25. GT Services is also reimbursed for
its out-of-pocket expenses for such items as postage, forms, telephone charges,
stationery and office supplies.
 
The Trust pays each of its Trustees who is not an employee, officer or director
of the Manager, GT Global or GT Services $5,000 per year plus $300 for each
meeting of the board or any committee thereof attended by the Trustee.

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.

                                DISTRIBUTION CONTRACT
                                    CLASS C SHARES
                                       BETWEEN
                               GT GLOBAL SERIES TRUST
                                         AND
                                  GT GLOBAL, INC.

   
     THIS DISTRIBUTION CONTRACT ("Contract"), is made as of December 10, 1997,
between GT GLOBAL SERIES TRUST, a Massachusetts business trust ("Trust"), and GT
GLOBAL, INC., a California corporation ("GT Global").
    

     WHEREAS, the Trust is registered under the Investment Company Act of 1940,
as amended ("1940 Act"), as an open-end management investment company; and

     WHEREAS, the Trust's Board of Trustees ("Board") has established GT Global
New Dimension Fund ("New Dimension Fund") as the initial series of shares of
beneficial interest in the Trust; and

     WHEREAS, the Trust hereafter may establish additional series of shares of
beneficial interest in the Trust (any such additional series together with the
New Dimension Fund collectively are referred to herein as the "Funds," and
singly may be referred to as a "Fund"); and

     WHEREAS, the Board has established Class A, Class B, Class C, and Advisor
Class shares of beneficial interest in each such Fund; and

     WHEREAS, the Trust desires to retain GT Global to act as the principal
underwriter of the Class C shares of the Funds, and GT Global is willing to act
in such capacity;

     NOW, THEREFORE, the parties agree as follows:

     1.   GT Global shall be the exclusive principal underwriter for the sale of
Class C shares of each Fund, except as otherwise provided pursuant to paragraph
20 hereof.  The terms "Class C shares of the Fund" or "Class C shares" as used
herein shall mean Class C shares of beneficial interest issued by the Funds.

     2.   In the sale of Class C shares of each Fund, GT Global shall act as
agent of the Trust except in any transaction in which GT Global sells such Class
C shares as a dealer to the public, in which event GT Global shall act as
principal for its own account.


<PAGE>

     3.   The Trust shall sell Class C shares only through GT Global except that
the Trust may at any time:

          (a)  Issue Class C shares to any corporation, association, trust,
               partnership, or other organization, or its, or their, security
               holders, beneficiaries, or members, in connection with a merger,
               consolidation, or reorganization to which the Trust is a party,
               or in connection with the acquisition of all or substantially all
               the property and assets of such corporation, association, trust,
               partnership, or other organization;

          (b)  Issue Class C shares of a Fund to the holders of Class C shares
               of the other Funds or Class C shares of other investment
               companies managed by Chancellor LGT Asset Management, Inc.,
               pursuant to any exchange or reinvestment option made available as
               described in the current Prospectus of the Fund;

          (c)  Issue Class C shares to a Fund's shareholders in connection with
               the reinvestment of dividends and other distributions paid by the
               Fund;

          (d)  Issue Class C shares of a Fund to Trustees, officers, and
               employees of the Trust, its investment manager, any principal
               underwriter of the Trust, and their affiliates, including any
               trust, pension, profit-sharing, or other benefit plan established
               for such persons, registered representatives and other employees
               of dealers having Dealer Agreements with GT Global and with
               respect to all such persons listed, their respective spouse,
               siblings, parents and children, and to other persons as permitted
               by applicable rules adopted by the Securities and Exchange
               Commission under the 1940 Act, as in effect from time to time and
               as described in the current Prospectus of the Fund;

          (e)  Issue Class C shares of a Fund to the sponsor organization,
               custodian or depository of a periodic or single payment plan, or
               similar plan for the purchase of Class C shares of the Fund,
               purchasing for such plan;


                                         -2-
<PAGE>

          (f)  Issue Class C shares of a Fund in the course of any other
               transaction specifically provided for in the Prospectus of the
               Funds, or upon obtaining the written consent of GT Global
               thereto; or

          (g)  Sell Class C shares outside of the North American continent,
               Hawaii and Puerto Rico through such other principal underwriter
               or principal underwriters as may be designated from time to time
               by the Trust, pursuant to paragraph 20 hereof.

     4.   GT Global shall devote its best efforts to the sale of Class C shares
of the Funds.  GT Global shall maintain a sales organization suited to the sale
of Class C shares of the Funds and shall use its best efforts to effect such
sales in countries as to which the Trust shall have expressly waived in writing
its right to designate another principal underwriter pursuant to paragraph 20
hereof, and shall effect and maintain appropriate qualification to do so in all
those jurisdictions in which it sells or offers Class C shares for sale and in
which qualification is required.

     5.   Within the United States of America, GT Global shall offer and sell
Class C shares only to or through such dealers as are members in good standing
of the National Association of Securities Dealers, Inc. ("NASD"), or to persons
legally engaged in dealer activities who are exempt from NASD membership in
accord with applicable law.  Class C shares of a Fund sold to dealers shall be
for resale by such dealers only at the public offering price set forth in the
effective Prospectus relating to the Fund which is part of the Trust's
Registration Statement in effect under the Securities Act of 1933, as amended
("1933 Act"), at the time of such offer or sale (herein, the "Prospectus").

     6.   In its sales to dealers, GT Global shall use its best efforts to
determine that such dealers are appropriately qualified to transact business in
securities under applicable laws, rules and regulations promulgated by such
national, state, local or other governmental or quasi-governmental authorities
as may in a particular instance have jurisdiction.

     7.   The applicable public offering price of Class C shares of a Fund shall
be the price which is equal to the net asset value per Class C share.  Net asset
value per Class C share shall be determined for a Fund in the manner and at the
time or times set forth in and subject to the provisions of its Prospectus.


                                         -3-
<PAGE>

     8.   All orders for Class C shares received by GT Global shall, unless
rejected by GT Global or the Trust, be accepted by GT Global immediately upon
receipt and confirmed at an offering price determined in accordance with the
provisions of the Prospectus and the 1940 Act, and applicable rules in effect
thereunder.  GT Global shall not hold orders subject to acceptance nor otherwise
delay their execution.  In conformity with the rules of the NASD, GT Global
shall not accept conditional orders.  The provisions of this paragraph shall not
be construed to restrict the right of the Trust to withhold Class C shares of
the Funds from sale under paragraph 16 hereof.

     9.   The Trust or its transfer agent shall be promptly advised of all
orders received, and shall cause Class C shares of the Funds to be issued upon
payment received in accord with policies established by the Trust and GT Global.

     10.  GT Global shall adopt and follow procedures as approved by the
officers of the Trust for the confirmation of sales to dealers, the collection
of amounts payable by dealers on such sales, and the cancellation of unsettled
transactions, as may be necessary to comply with the requirements of the NASD
and the 1940 Act, as such requirements may from time to time exist.

     11.  The compensation for the services of GT Global as a principal
underwriter under this Contract shall be all contingent deferred sales charges
that may be imposed on redemptions of Class C shares.  In addition, GT Global is
entitled to fees, if any, payable under the Trust's Plan of Distribution
applicable to the Class C shares of the Funds ("Class C Plan").

     12.  The Trust agrees to use its best efforts to maintain its registration
as an open-end management investment company under the 1940 Act.

     13.  The Trust agrees to use its best efforts to maintain an effective
prospectus relating to each Fund under the 1933 Act, and warrants that such
prospectus will contain all statements required by and will conform with the
requirements of the 1933 Act and the rules and regulations thereunder, and that
no part of any such prospectus, at the time the Registration Statement of which
it is a part is ordered effective, will contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein, or
necessary to make the statements therein not misleading.  GT Global agrees and
warrants that it will not in the sale of Class C shares of the Funds use any
prospectus, advertising or sales literature not approved by


                                         -4-
<PAGE>

the Trust or its officers nor make any untrue statement of a material fact nor
omit the stating of a material fact necessary in order to make the statements
made, in the light of the circumstances under which they are made, not
misleading.  GT Global agrees to indemnify and hold the Trust harmless from any
and all loss, expense, damage and liability resulting from a breach by GT Global
of the agreements and warranties in this paragraph, or from the use of any sales
literature, information, statistics or other aid or device employed in
connection with the sale of Class C shares.

     14.  The expense of each printing of each Prospectus and each revision
thereof or addition thereto deemed necessary by the Trust's officers to meet the
requirements of applicable laws shall be divided between the Trust, GT Global
and any other principal underwriter of the Class C shares of the Funds as they
may from time to time agree.

     15.  The Trust agrees to use its best efforts to qualify and maintain the
qualification of an appropriate number of the Class C shares of each Fund for
sale under the securities laws of such states as GT Global and the Trust may
approve.  Any such qualification may be withheld, terminated or withdrawn by the
Trust at any time in its discretion.  The expense of qualification and
maintenance of qualification shall be borne by the Trust, but GT Global shall
furnish such information and other materials relating to its affairs and
activities as may be required by the Trust or its counsel in connection with
such qualification.

     16.  The Trust and GT Global acknowledge that each has the right to reject
any order for the purchase of Class C shares for any reason.  In addition, the
Trust may withhold Class C shares from sale in any state or country temporarily
or permanently if, in the opinion of its counsel, such offer or sale would be
contrary to law or if the Board or the President or any Vice President of the
Trust determines that such offer or sale is not in the best interest of the
Trust.  The Trust will give prompt notice to GT Global of any withholding and
will indemnify it against any loss suffered by GT Global as a result of such
withholding by reason of non-delivery of Class C shares after a good faith
confirmation by GT Global of sales thereof prior to receipt of notice of such
withholding.

     17.  Each Fund shall reimburse GT Global for a portion of its expenditures
incurred in providing services under this Contract at the rate and under the
terms specified with respect


                                         -5-
<PAGE>

to such Fund in the Class C Plan, as such Plan may be amended from time to time.

     18.  (a)  With respect to any Fund, this Contract may be terminated at any
               time, without payment of any penalty, by vote of a majority of
               the members of the Board who are not interested persons of the
               Trust and have no direct or indirect financial interest in the
               operation of the Plan or in any agreements related to the Plan or
               by vote of a majority of the outstanding voting securities of the
               Fund on thirty (30) days' written notice to GT Global, or by GT
               Global on like notice to the Trust.  Termination of this Contract
               with respect to Class C shares of one Fund shall not affect its
               continued effectiveness with respect to Class C shares of any
               other Fund.

          (b)  This Contract may be terminated by either party upon five (5)
               days' written notice to the other party in the event that the
               Securities and Exchange Commission has issued an order or
               obtained an injunction or other court order suspending
               effectiveness of the Registration Statement covering the Class C
               shares of the Funds.

          (c)  This Contract may also be terminated by the Trust upon five (5)
               days' written notice to GT Global, should the NASD expel GT
               Global or suspend its membership in that organization.

          (d)  GT Global shall inform the Trust promptly of the institution of
               any proceedings against it by the Securities and Exchange
               Commission, the NASD or any state regulatory authority.

     19.  This Agreement shall automatically terminate in the event of its
assignment.  The term "assignment" shall have the meaning defined in the 1940
Act.

     20.  With respect to any Fund, upon sixty (60) days' written notice to GT
Global, the Trust may from time to time designate other principal underwriters
of Class C shares with respect to areas other than the North American continent,
Hawaii, Puerto Rico and such countries as to which the Trust may have expressly
waived in writing its right to make such designation.  In the event of such
designation, the right of GT Global under this



                                         -6-
<PAGE>

Contract to sell Class C shares in the areas so designated shall terminate, but
this Contract shall remain otherwise in full effect until terminated in
accordance with the provisions of paragraphs 18 and 19 hereof.

     21.  No provision of this Contract shall protect or purport to protect GT
Global against any liability to the Trust or holders of Class C shares of the
Funds for which GT Global would otherwise be liable by reason of willful
misfeasance, bad faith or negligence.

     22.  Unless sooner terminated in accordance with the provisions of
paragraphs 18 or 19 hereof, this Contract shall continue in effect with respect
to each Fund for periods of up to one year, but only so long as such continuance
is specifically approved at least annually (i) by vote of a majority of the
Trustees of the Trust who are not interested persons of the Trust and who have
no direct or indirect financial interest in the Plan or any agreements relating
to the Plan, and who are not parties to this Contract or interested persons of
any such party as defined by the 1940 Act, cast in person at a meeting called
for the purpose of voting on such approval; and (ii) by either the Board or a
vote of a majority of the outstanding Class C shares of the Trust as defined by
the 1940 Act.

     23.  It is expressly agreed that the obligations of the Trust hereunder
shall not be binding upon any of the Trustees, shareholders, nominees, officers,
agents or employees of the Trust personally, but shall only bind the assets and
property of the Funds, as provided in the Trust's Declaration of Trust.  The
execution and delivery of this Contract have been authorized by the Trustees of
the Trust, and this Contract has been executed and delivered by an authorized
officer of the Trust acting as such; neither such authorization by such Trustees
nor such execution and delivery by such officer shall be deemed to have been
made by any of them individually or to impose any liability on any of them
personally, but shall bind only the assets and property of the Funds, as
provided in the Trust's Declaration of Trust.

     IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
executed in duplicate original by their officers thereunder duly authorized as
of the day and year first written above.

     RE:  SUPPLEMENTARY DEALER AGREEMENT - CLASS C SHARES

Reference is made to the Dealer Agreement ("Dealer Agreement") previously
entered into between You and GT Global, Inc. ("Us" or "We"), as general
distributor and principal underwriter, as such term is defined in the Investment
Company Act of 1940, as amended ("1940 Act"), of the shares of the mutual funds
that now or hereafter may be included in the GT Global Group of Funds ("Funds").
The Dealer Agreement is incorporated herein by reference and all the terms of
the Dealer Agreement shall continue in full force and effect.

This Supplementary Dealer Agreement ("Supplementary Agreement") relates solely

and the terms of the Dealer Agreement, we offer to sell to you, as dealer for
your account, Class C Shares, subject to any limitations imposed by the Funds
and subject to confirmation by Us in each instance.  All references to "Class A
shares and Class B shares" in the Dealer Agreement are hereby amended to include
"Class A shares, Class B shares and Class C shares," and all references to
"Class A or Class B shares" are hereby amended to include "Class A, Class B or
Class C shares."

1.  You are to offer Class C Shares only at the public offering price, which is

                               PLAN OF DISTRIBUTION OF
                       GT GLOBAL SERIES TRUST -- CLASS C SHARES


     WHEREAS, GT Global Series Trust ("Trust") is registered under the
Investment Company Act of 1940, as amended ("1940 Act"), as an open-end
management investment company, and offers for public sale distinct series of
shares of beneficial interest; and

     WHEREAS, the Trust's Board of Trustees ("Board") has established GT Global
New Dimension Fund ("New Dimension Fund") as the initial series of shares of
beneficial interest in the Trust; and

     WHEREAS, the Trust hereafter may establish additional series of shares of
beneficial interest in the Trust (any such additional series together with the
New Dimension Fund collectively are referred to herein as the "Funds," and
singly may be referred to as a "Fund"); and

     WHEREAS, the Board has established Class A, Class B, Class C, and Advisor
Class shares of each Fund; and

     WHEREAS, the Trust desires to adopt a Plan pursuant to Rule 12b-1 under the
1940 Act with respect to the Class C shares of each such Fund; and

     WHEREAS, the Trust has entered into a Distribution Contract ("Distribution
Contract") with GT Global, Inc. ("GT Global" or "Distributor") pursuant to which
GT Global serves as Distributor of the Class C shares of each such Fund and
pursuant to which GT Global is entitled to receive payments of contingent
deferred sales charges imposed with respect to certain redemptions of Class C
shares;

     NOW, THEREFORE, the Trust hereby adopts this Plan with respect to the Class
C shares of each Fund in accordance with Rule 12b-1 under the 1940 Act.

     1.   A.   Each Fund is authorized to pay GT Global for its expenditures
               incurred in providing services as Distributor of the Fund's Class
               C shares at the annualized rate of up to 0.75% of the average
               daily net assets of the Fund's Class C shares.

          B.   Each Fund is authorized to pay GT Global a service fee for the
               Fund's Class C shares at the


<PAGE>

               annualized rate of up to 0.25% of the average daily net assets of
               the Fund's Class C shares.

          C.   If the Trust establishes additional Funds in the future and the
               applicability of the Plan with respect to such Funds is approved
               in the manner set forth in paragraph 4 of this Plan, this Plan
               may be amended to provide that each such additional Fund will
               reimburse GT Global at rates to be established by the Board.

          D.   Reimbursement amounts under this Plan shall be calculated and
               accrued daily by each Fund and paid monthly to GT Global or at
               such other intervals as the Trust and GT Global shall agree.

          E.   Each Fund shall accrue and carry forward amounts reimbursable
               that are not paid because they exceed the annualized rate of
               0.75%, in the case of distribution fees, and 0.25%, in the case
               of service fees, of the average daily net assets of such Fund's
               Class C shares and shall pay such amounts within the 0.75% and
               0.25% per annum payment rate limitations as long as this Plan,
               including any amendments hereto, is in effect.

     2.   A Fund may reimburse GT Global at a lesser rate than the fee specified
in paragraph 1 of this Plan, as agreed upon by the Board and GT Global and as
approved in the manner specified in paragraph 4 of this Plan.  The terms of
paragraph 1.E. of this Plan shall apply to such lesser agreed upon rate, if any.
Although a Fund is not liable for unreimbursed distribution expenses, in the
event of termination or discontinuation of the Plan, the Board may consider the
appropriateness of having the Class C shares of the Fund reimburse GT Global for
the then outstanding carry forward amounts plus interest thereon to the extent
permitted by applicable law from the effective date of the Plan.

     3.   As Distributor of the Funds' Class C shares, GT Global may spend such
amounts as it deems appropriate on any activities or expenses primarily intended
to result in the sale of each Fund's Class C shares and the servicing and
maintenance of shareholder accounts, including, but not limited to, payment of
sales commissions, ongoing commissions and other payments to brokers, dealers,
financial institutions or others who sell Class C shares and/or service Class C
shareholder accounts; compensation to employees of GT Global; compensation to
and


                                         -2-
<PAGE>

expenses, including overhead and telephone expenses, of GT Global; the printing
of prospectuses, statements of additional information and reports for other than
existing Class C shareholders; and the preparation, printing and distribution of
sales literature and advertising materials.  In addition, GT Global may be
entitled, to the extent permitted by applicable law, to interest on unreimbursed
amounts carried forward pursuant to paragraph 1.E. hereunder at a rate equal to
that paid by GT Global for bank borrowings.  Proceeds from contingent deferred
sales charges received by GT Global (in connection with the redemption of Fund
shares) will be applied to reduce the costs incurred as described above.

     4.   This Plan shall take effect with respect to the Class C shares of any
Fund, together with any related agreements, immediately after it has been
approved by votes of a majority of both (a) the Board and (b) those Trustees of
the Trust who are not interested persons of the Trust and have no direct or
indirect financial interest in the operation of this Plan or any agreements
related thereto ("Independent Trustees"), cast in person at a meeting (or
meetings) called for the purpose of voting on such approval; and after the
Trustees who approve the Plan with respect to such Fund's Class C shares have
reached the conclusion required by Rule 12b-1(e) under the 1940 Act.

     5.   The Plan shall continue in effect for so long as such continuance is
specifically approved at least annually in the manner provided in paragraph 4.

     6.   GT Global shall provide to the Board and the Independent Trustees
shall review and approve, in exercise of their fiduciary duties, at least
quarterly, a written report of the amounts expended with respect to the Class C
shares of each Fund by GT Global under this Plan and the Distribution Contract
and the purposes for which such expenditures were made.

     7.   For purposes of this Plan, "distribution fees" shall mean any fees for
activities in connection with GT Global's performance of its obligations under
the Plan or the Distribution Contract that are not deemed "service fees."
"Service fees" shall mean fees for activities covered by the definition of
"service fee" contained in Conduct Rule 2830 of the National Association of
Securities Dealers, Inc.

     8.   This Plan may be terminated at any time with respect to the Class C
shares of any Fund by vote of the Board, by vote of a majority of the
Independent Trustees, or by vote of a majority of the outstanding voting
securities of the Class C shares of that



                                         -3-
<PAGE>

Fund.  Termination of the Plan with respect to the Class C shares of one Fund
shall not affect the continued effectiveness of this Plan with respect to the
Class C shares of any other Fund.

     9.   This Plan may not be amended to increase materially the amount of
reimbursement a Fund is authorized to make under paragraph 1 hereof unless such
amendment is approved in the manner provided for initial approval in paragraph 4
hereof, and such amendment is further approved by a majority of the outstanding
voting securities of the Class C shares of that Fund, and no other material
amendment to the Plan shall be made unless approved in the manner provided for
approval and annual renewal in paragraph 5 hereof.

     10.  If and to the extent that any of the expenses of the Class C shares of
a Fund listed below in this paragraph are considered to be "primarily intended
to result in the sale of shares" issued by the Fund within the meaning of Rule
12b-1 under the 1940 Act, the Fund's payment of such expenses is authorized
without limit under this Plan, without regard to reimbursements made by the Fund
pursuant to paragraph 1 of this Plan or the requirements for approval of any
increase in such fees under paragraph 9 of this Plan.  These expenses include:
(i) the costs of preparing, printing and mailing all required reports and
notices to Class C shareholders, irrespective of whether such reports or notices
contain or are accompanied by material intended to result in the sale of Class C
shares of the Fund or other funds or other investments; (ii) the costs of
preparing, printing and mailing all prospectuses; (iii) the costs of preparing,
printing and mailing any proxy statements and proxies, irrespective of whether
such proxy statements include any item relating to, or directed toward, the sale
of the Fund's Class C shares; (iv) all legal and accounting fees relating to the
preparation of any such reports, prospectuses, proxies and proxy statements;
(v) all fees and expenses relating to the qualification of the Fund and/or its
Class C shares under the securities or "Blue Sky" laws of any jurisdiction;
(vi) all fees under the 1940 Act and the Securities Act of 1933, including fees
in connection with any application for exemption relating to or directed toward
the sale of the Fund's Class C shares; (vii) all fees and assessments of the
Investment Company Institute or any successor organization, irrespective of
whether some of its activities are designed to provide sales assistance;
(viii) all costs of processing Class C share transactions, preparing and mailing
confirmations of Class C shares sold or redeemed or share certificates, and
reports of Class C share balances; and (ix) all costs of responding to telephone
or mail inquiries of investors or prospective investors.


                                         -4-

     11.  It is recognized that the costs of distributing a Fund's Class C
shares may exceed the sum of the contingent deferred sales charges collected on
sales of Class C shares of such Fund and reimbursements made by that Fund
pursuant to paragraph 1 of this Plan.  In view of this, if and to the extent
that any investment management and administration fees paid by a Fund might be
considered as indirectly financing any activity which is primarily intended to
result in the sale of that Fund's Class C shares, the payment by that Fund of
such fees hereby is authorized under this Plan.

     12.  While this Plan is in effect, the selection and nomination of Trustees
who are not interested persons of the Trust shall be committed to the discretion
of the Trustees who are not interested persons of the Trust.

     13.  As used in this Plan, the terms "majority of the outstanding voting
securities" and "interested person" shall have the same meanings as those terms
have in the 1940 Act.

     14.  The Trust shall preserve copies of this Plan (including any amendments
thereto) and any related agreements and all reports made pursuant to paragraph 6
thereof for a period of not less than six years from the date of this Plan, the
first two years in an easily accessible place.

     15.  The Trustees of the Trust and the shareholders of each Fund shall not
be liable for any obligations of the Trust or any Fund under this Plan, and GT
Global or any other person, in asserting any rights or claims under this Plan,
shall look only to the assets and property of the Trust or such Fund in
settlement of such right or claim, and not to such Trustees or shareholders.
   
     IN WITNESS WHEREOF, the Trust has executed this Plan of Distribution on
December 31, 1997.

                                GT GLOBAL SERIES TRUST
                  AMENDED MULTIPLE CLASS PLAN PURSUANT TO RULE 18f-3

     GT Global Series Trust ("Trust") hereby adopts this Amended Multiple Class
Plan pursuant to Rule 18f-3 under the Investment Company Act of 1940, as amended
(the "1940 Act") on behalf of its current series, GT Global New Dimension Fund,
and any series that may commence operations in the future (referred to
hereinafter as the "Fund").  

A.   GENERAL DESCRIPTION OF CLASSES THAT ARE OFFERED  

     1.   CLASS A SHARES.  Class A shares of the Fund are sold to the general
public subject to an initial sales charge of up to 4.75% of the public offering
price.  The initial sales charge is waived for certain eligible purchasers and
reduced or waived for certain large volume purchases, all as set forth in the
prospectus of the Trust.

     Class A shares of the Fund are subject to a "service" fee at the annualized
rate of up to 0.25% of the average daily net assets for the Fund's Class A
shares.  Class A shares of the Fund also are subject to a "distribution" fee at
the annualized rate of up to 0.50% of the average daily net assets for the
Fund's Class A shares, less any amounts paid by the Fund as the aforementioned
service fee. Such fees are paid pursuant to a plan of distribution adopted in
accordance with Rule 12b-1 under the 1940 Act.

     Class A shares of the Fund that are purchased without an initial sales
charge due to the sales charge waiver for purchases of $500,000 or more are
subject to a contingent deferred sales charge ("CDSC") on redemptions of shares
made within one year after the date of purchase.  The Class A CDSC is equal to
1% of the lower of (i) the original purchase price, or (ii) the net asset value
of the shares at the time of redemption.  Class A shares that are redeemed will
not be subject to a CDSC to the extent that the value of such shares represents:
(i) reinvestment of dividends or other distributions, or (ii) Class A shares
redeemed one year or more after their purchase.  Class A shares purchased in
amounts of at least $500,000 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 CDSC, although the CDSC will apply to the redemption
of the shares acquired through an exchange.  

     2.   CLASS B SHARES.  Class B shares of the Fund are sold to the general
public without imposition of an initial sales charge; however, a CDSC is imposed
on certain redemptions of Class B shares.  The maximum CDSC for Class B shares
is equal to 5% of the lesser of the original purchase price or the net asset
value of the shares at the time of redemption.  The CDSC is waived for certain
exchanges and redemptions. 

     Class B shares that are redeemed will not be subject to a CDSC to the
extent that the value of such shares represents:  (i) reinvestment of dividends
or other distributions, or (ii) shares redeemed more than six years after their
purchase.
<PAGE>

     Class B shares are subject to a service fee at the annualized rate of up to
0.25% of the average daily net assets of the Class B shares of the Fund and a
distribution fee at the annualized rate of up to 0.75% of the average daily net
assets of the Fund's Class B shares.  Such fees are paid pursuant to a plan of
distribution adopted in accordance with Rule 12b-1 under the 1940 Act.

     Class B shares automatically will convert to Class A shares as of the close
of business on the last business day of the month in which the seventh
anniversary of the initial issuance of such Class B shares occurs. For purposes
of calculating the holding period required for conversion of Class B shares, the
initial issuance date is (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.  The
conversion would be effected at the relative net asset value per share of each
class.  At the time of conversion, a portion of Class B shares owned as a result
of reinvestment of dividends or other distributions ("Dividend Shares") also
would convert to Class A shares.  The portion of Dividend Shares that would
convert would be determined by the ratio of converting Class B non-Dividend
Shares to the total Class B non-Dividend Shares held by the shareholder.

     3.   CLASS C SHARES.  Class C shares of the Fund are sold to the general
public without imposition of an initial sales charge; however, a CDSC equal to
1% of the lesser of the original purchase price or the net asset value of the
shares at the time of redemption is imposed on certain redemptions of Class C
shares made within one year of purchase.  Class C shares that are redeemed will
not be subject to a CDSC to the extent that the value of such shares represents:
(i) reinvestment of dividends or other distributions, or (ii) shares redeemed
more than one year after their purchase.

     Class C shares are subject to a service fee at the annualized rate of up to
0.25% of the average daily net assets of the Class C shares of the Fund and a
distribution fee at the annualized rate of up to 0.75% of the average daily net
assets of the Fund's Class C shares.  Such fees are paid pursuant to a plan of

B.   EXPENSE ALLOCATIONS OF EACH CLASS

     Certain expenses may be attributable to a particular Class of shares
("Class Expenses").  Class Expenses are charged directly to the net assets of
the particular Class and, thus, are borne on a pro rata basis by the outstanding
shares of that Class.

     In addition to the service and distribution fees described above, each
Class also could pay a different amount of the following other expenses:

          (1)  transfer agent fees identified as being attributable to a
               specific Class of shares; 

          (2)  stationery, printing, postage, and delivery expenses related to
               preparing and distributing materials such as shareholder reports,
               prospectuses, and proxy statements to current shareholders of a
               specific Class of shares;

          (3)  Blue Sky fees incurred by a specific Class of shares;

          (4)  SEC registration fees incurred by a specific Class of shares;

          (5)  expenses of administrative personnel and services as required to
