ABOUT FUND PERFORMANCE AND PORTFOLIO DATA THROUGHOUT 
THIS REPORT:

- --     AIM Global Trends Fund (formerly GT Global New Dimension Fund) 
       performance figures are historical and reflect reinvestment of all 
       distributions and changes in net asset value. Unless otherwise 
       indicated, the Fund's performance is computed at net asset value 
       without a sales charge.

- --     During the fiscal year ended 12/31/98 the Fund paid the following 
       distributions: Class A shares, $0.16 per share; Class B and Class C 
       shares, $0.14 per share; Advisor Class, $0.22 per share.

- --     When sales charges are included in performance figures, Class A share 
       performance reflects the maximum 4.75% sales charge. Class B and Class 
       C share performance reflects the applicable contingent deferred sales 
       charge (CDSC) for the period involved. The CDSC on Class B shares 
       declines from 5% beginning at the time of purchase to 0% at the 
       beginning of the seventh year. The CDSC on Class C shares is 1% for 
       the first year after purchase. The performance of the Fund's Class B 
       shares and Class C will differ from that of Class A shares due to 
       differences in sales charge structure and Fund expenses.

- --     Advisor Class shares are not sold directly to the general public and 
       are available only through certain employee benefit plans, financial 
       institutions and other entities that have entered into specific 
       agreements with the Fund's Distributor. Please see the Fund's Advisor 
       Class prospectus for more complete information.

- --     The Fund's investment return and principal value will fluctuate so 
       that an investor's shares, when redeemed, may be worth more or less 
       than their original cost.

- --     International investing presents certain risks not associated with 
       investing solely in the United States.  These include risks relating 
       to fluctuations in the value of the U.S. dollar relative to the values 
       of other currencies, the custody arrangements made for the Fund's 
       foreign holdings, differences in accounting, political risks, and the 
       lesser degree of public information required to be provided by 
       non-U.S. companies.

[PHOTO OF 
Charles T. Bauer, 
Chairman of the 
Board of the 
Fund APPEARS HERE]
                      DEAR FELLOW SHAREHOLDER:
                      As the fiscal year opened, markets were recovering from 
                      the concerns produced by financial crises in Asia 
                      during 1997, and this optimism early in 1998 led 
                      several market indexes to all-time highs in spring and 
                      early summer. However, the year was to bring two 
                      particularly serious financial shocks, first the debt 
                      default by Russia, and later the gathering crisis in 
                      Brazil, which devalued its currency shortly after the 
                      fiscal year closed. The result was another year of 
                      significant market volatility. Optimism yielded to 
                      pessimism over the summer as global financial crises 
                      precipitated a worldwide loss of confidence that 
                      affected even previously high-flying U.S. blue chips 
                      and market-leading European stocks. 

                        Beginning in late September, the U.S. Federal Reserve 
                      Board intervened to pump liquidity and confidence into 
                      markets. Numerous interest rate cuts in other countries 
                      followed. Investors responded favorably. Europe and the 
                      U.S. regained their market leadership, but investors in 
                      most emerging markets suffered serious financial loss 
                      over the year.

                      HOW SHOULD INVESTORS RESPOND?

                      We understood how unnerving 1998's level of volatility 
                      could have been. Our repeated message to you is to keep 
                      a long-term outlook on investments rather than 
                      responding to short-term fluctuations. And we are 
                      pleased to note that most mutual fund shareholders 
                      remained cool headed and did not pull out of the 
                      markets during 1998. In the end, most were rewarded for 
                      their long-term perspective. 

                        In view of recent volatility and the divergent 
                      performance of market sectors, this may be a very good 
                      time to meet with your financial consultant to review 
                      your current asset allocation and the diversification 
                      of your portfolio. Broad portfolio diversification 
                      remains one of the most fundamental principles of 
                      investing, along with long-term thinking and realistic 
                      expectations.

 . . . WE ARE PLEASED 
TO NOTE THAT MOST 
MUTUAL FUND 
SHAREHOLDERS REMAINED 
COOL HEADED AND 
DID NOT PULL OUT OF THE 
MARKETS DURING 1998.

                      YOUR FUND MANAGERS' COMMENTS

                      On the pages that follow, your Fund's managers, 
                      experienced professionals who have weathered previous 
                      periods of market turbulence, offer more detailed 
                      discussion of how markets behaved, how they managed the 
                      portfolio in light of recent volatility, and what they 
                      foresee for markets and your Fund. We hope you find 
                      their discussion informative. 

                      BROADENED INVESTMENTS PLANNED

                      After the close of the fiscal year, AIM planned to 
                      broaden the investment strategy of one of the funds in 
                      which AIM Global Trends Fund invests. Effective June 1, 
                      1999, AIM Global Telecommunications Fund will include 
                      technology-sector investments in its portfolio. At that 
                      time, we anticipate renaming the Fund AIM Global 
                      Telecommunications and Technology Fund to reflect its 
                      exposure to both sectors. 

                      YEAR 2000 CONCERN

                      Many of our shareholders have asked us about AIM's year 
                      2000 readiness status. We appreciate these concerns, 
                      and we take the year 2000 issue seriously. AIM has 
                      devoted considerable effort to creating a comprehensive 
                      plan for assessing, correcting and testing our in-house 
                      systems. We will also participate in an industrywide 
                      testing effort scheduled to begin in March. But no 
                      matter how well we prepare and test, no one can know 
                      for sure what the year 2000 will bring. Our industry's 
                      systems are connected in complex ways to many third 
                      parties, and there may be unforeseen problems when the 
                      year 2000 actually arrives. Though we cannot predict 
                      what all those problems might be, we are working with 
                      our business recovery team to develop contingency plans 
                      appropriate for a variety of year 2000 scenarios.

                        We are pleased to send you this report on your Fund's 
                      fiscal year. If you have any questions or comments, 
                      please contact our Client Services department at

                      account through our AIM Investor Line at 800-246-5463

                         ANNUAL REPORT / MANAGERS' OVERVIEW

GLOBAL DIVERSIFICATION OFFERS ADVANTAGE IN TURBULENT MARKET

GLOBAL FINANCIAL MARKETS EXPERIENCED INTENSE VOLATILITY IN 1998. HOW DID THE 
FUND PERFORM IN THIS ENVIRONMENT?

The Fund reported solid annual total returns of 9.37% for Class A shares, 
8.83% for Class B shares, and 9.80% for Advisor Class shares. The Fund began 
offering Class C shares on January 2, 1998, and their cumulative annual 
return from inception to end of the fiscal year was 8.94%.

  The Fund is an actively managed blend of six AIM Global Theme Funds, which 
invest in companies across several industries. Theme funds invest in industry 
groups tied together by an economic or social theme. Managers of the AIM 
Global Trends Fund allocate its assets among the six theme funds according to 
industry weightings in the MSCI All Country World Index. (Please see the 
sidebar on page 3 for the investment strategies of each of the six theme 
funds.)   

WHAT WERE THE MAJOR TRENDS IN THE WORLD MARKETS OVER THE FISCAL YEAR?

We would describe 1998 as a market with three definite phases. During the 
first stage, from January to mid-July, the bull market climbed, spurred by 
strong economies in the United States and Europe. But by summer these good 
sentiments began to disintegrate. In July the market entered its second 
phase, abruptly declining. By August, market indexes such as the Dow plunged. 
A convergence of international problems triggered the downturn: currency 
devaluation in Southeast Asia, lingering recession in Japan, and Russian 
default on foreign debt. 

  The third phase came in October as markets stabilized and rallied, spurred 
by a series of interest rate cuts. Over the course of seven weeks, the U.S. 
Federal Reserve Board lowered the key federal funds rate from 5.50% to 4.75%. 
The three cuts triggered an astounding market rally. By the end of the fiscal 
year, major stock and bond indexes reported impressive total returns: the S&P 
500, up 28.6%; the MSCI World Index, up 24.3%; and the Lehman Aggregate Bond 
Index, up 8.7%.

</TABLE>

[Pie Chart]


THE FUND'S LARGEST ALLOCATION WAS IN THE AIM GLOBAL CONSUMER PRODUCTS AND 
SERVICES FUND. HOW DID IT PERFORM?

Consumer products and services stocks are benefiting from increased consumer 
spending, encouraged by lower interest rates and low inflation. The AIM 
Global Consumer Products and Services Fund focused on large-cap companies 
based in the United States, the United Kingdom, Europe, Canada and Australia. 
In the current environment with the economy expected to slow, the Fund turned 
to more conservative and established domestic large-cap companies for growth 
in fiscal 1998. These included industry leaders such as Microsoft and GE. The 
Fund also emphasized companies with consumer staple-type products and 
services that sell even during a weaker economy. The Fund's top holdings were 
household names with strong brand recognition, such as Heineken, Dial, Clorox 
and Safeway.

  Until global markets stabilize, this Fund will continue to focus on more 
predictable, large-company holdings in developed countries. 

IT WAS A DIFFICULT YEAR FOR MANY FINANCIAL STOCKS. WHAT WAS THE EFFECT OF MARKET
TURMOIL ON THE AIM GLOBAL FINANCIAL SERVICES FUND?

Financial markets were battered by unfavorable news in Asia, Russia and Latin 
America and the near collapse of a major hedge fund. 

  The Fund sold several holdings that were particularly market sensitive, 
including stocks of brokerage firms, trading banks, and European banks with 
Russian exposure. It acquired defensive stocks such as regional banks and 
insurance companies that were less affected by the emerging market crisis. 
The Fund had no significant Asian exposure during the fiscal year and had a 
sizable European presence in healthy economies such as Ireland and the 
Netherlands.

  Many financial-services stocks currently held by the Fund represent 
significant value in the wake of the market sell-off earlier this year. This 
factor combined with the Fund's defensive holdings in regional banks and 
insurance companies positions it well for 1999, we believe.

HOW DID THE AIM GLOBAL INFRASTRUCTURE FUND PERFORM?

Infrastructure companies were hit hard by investors' fears that the credit 
crunch in emerging markets could spread to Europe and the United States, 
possibly halting growth.

  The Fund faced a number of challenges over the fiscal year because of its 
exposure to cyclically sensitive companies such as airlines, machinery 
makers, industrial components manufacturers and construction and engineering 
firms.

<PAGE>

                          ANNUAL REPORT / MANAGERS' OVERVIEW


  The Fund decreased its exposure in the weakest economies, mostly in 
emerging markets. It also lowered exposure to companies with significant 
sales to emerging markets such as airlines, long-haul freight, and 
commodity-oriented companies. The Fund redeployed these assets into utility 
stocks because of their defensive characteristics during volatile, uncertain 
markets. Fund managers expect to retain this high concentration in utility 
stocks as long as uncertainty prevails throughout most of the other 
infrastructure sectors. 

WHAT WERE THE MAJOR TRENDS FOR THE AIM GLOBAL HEALTH CARE FUND?

Stocks of large-cap pharmaceutical companies and medical-device makers soared 
in 1998. Drug manufacturers in particular experienced strong earnings growth 
because of pricing flexibility. They also continued to produce a steady 
stream of new drugs that were enthusiastically received by a health-conscious 
population. 

  The Fund changed its focus over the fiscal year as it dedicated more of its 
assets to large pharmaceutical companies such as Warner-Lambert and Merck. 
The fund reduced its stake in biotechnology and medical technology and supply 
firms because their stocks experienced weakness in 1998. In addition, the 
Fund increased its foreign exposure to take advantage of a strong economy in 
Europe.

BY THE END OF THE FISCAL YEAR, MAJOR STOCK AND BOND INDEXES REPORTED 
IMPRESSIVE TOTAL RETURNS.

HOW DID THE AIM GLOBAL RESOURCES FUND PERFORM IN FISCAL 1998?

The Fund experienced a challenging year because of the decline in commodity 
prices.

  The Fund increased its positions in the United States, with the rest of its 
investments in Europe, Canada, Australia and the United Kingdom. The Fund 
diversified into a number of commodity types, including cement, gypsum and 
gravel manufacturers, which remained relatively unaffected by market 
turbulence. The Fund also purchased stocks in companies with little commodity 
price risk, such as pipelines, propane distributors and uranium refiners. 
Among the Fund's best performing stocks were those of building materials 
companies. 

  Low commodity prices worldwide will continue to exert significant downward 
pressure on earnings of resource companies, increasing the risks and 
uncertainties of this type of investment. The Fund will continue to take a 
defensive position in more stable, large-company holdings in developed 
markets.

WHAT WERE THE MAJOR FACTORS INFLUENCING THE PERFORMANCE OF THE AIM GLOBAL 
TELECOMMUNICATIONS FUND IN 1998?

The AIM Global Telecommunications Fund put a greater emphasis on 
conservative, established telecommunications service and equipment companies 
such as GTE. It also increased holdings in wireless services and equipment, 
especially in Europe. Lower calling prices and increased competition 
continued to drive domestic and international growth in wireless 
communications. Holdings in Russia and Latin America were reduced because of 
economic difficulties there.

  The Fund will continue to focus on two principal areas of investment: 
conservative well-established global telephone companies and market leaders 
in equipment and technology with a proven ability to increase earnings.

WHAT IS YOUR OUTLOOK FOR GLOBAL FINANCIAL MARKETS IN GENERAL?

Recent political changes in Europe have introduced a few uncertainties, but 
overall, we're confident in the region. In early December, European markets 
soared when countries preparing to enter the European Economic and Monetary 
Union participated in a coordinated interest-rate cut.

  Many analysts believe Asia will hit bottom in 1999, indicating that growth 
and investor confidence may return some time next year. A Japanese bank 
bailout offers hope, but its implementation is far from clear.

  The U.S. economy is likely to experience annual gross domestic product 
growth in the 1.5% to 2% range, so we expect low inflation and low interest 
rates to continue.

Your Fund's total return includes sales charges, expenses, and management 
fees. For Fund data performance calculations and descriptions of indexes 
cited on this page, please refer to the inside front cover. The performance 
of the Fund's Class C shares will differ from that of other share classes due 
to differences in sales charge structure and Fund expenses.

ABOUT THIS CHART

The chart compares your Fund's Class A, Class B, and Advisor Class shares to 
a benchmark index. It is intended to give you a general idea of how your Fund 
performed compared to the stock market over the period 9/15/97- 12/31/98. It 
is important to understand differences between your Fund and an index. An 
index measures performance of a hypothetical portfolio. A market index such 
as the MSCI All Country World Index is not managed, incurring no sales 
charges, expenses or fees. (Please note that the results for this index are 
from 8/31/97-12/31/98). If you could buy all the securities that make up a 
market index, you would incur expenses that would affect the return on your 
investment.

1. SIGNIFICANT ACCOUNTING POLICIES
AIM Global Trends Fund (the "Fund"), formerly AIM New Dimension Fund and prior
to that GT Global New Dimension Fund is a diversified series of AIM Series Trust
(the "Trust"), formerly GT Global Series Trust. The Trust is organized as a
Delaware 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 AIM
theme mutual funds: AIM Global Consumer Products and Services Fund; AIM Global
Financial Services Fund; AIM Global Health Care Fund; AIM Global Infrastructure
Fund; AIM Global Resources Fund; and AIM Global Telecommunications Fund
(collectively, the "Underlying Theme Funds").
 
The Fund offers Class A, Class B, Class C, and Advisor Class shares, each of
which has equal rights as to assets and voting privileges. Class A, Class B, and
Class C, each have 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.
 
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 year. 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 Fund 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 of the Fund are valued based on the closing net asset value of
Advisor Class shares of each Underlying Theme Funds on the day of valuation, and
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. The Fund currently has a capital loss carryforward of
$731,153 which expires in 2006.
 
(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.
 
2. RELATED PARTIES
A I M Advisors, Inc. (the "Manager"), an indirectly wholly owned subsidiary of
AMVESCAP PLC, is the Fund's investment manager and administrator. As of the
close of business on May 29, 1998, Liechtenstein Global Trust AG ("LGT"), the
former indirect parent organization of Chancellor LGT Asset Management, Inc.
("Chancellor LGT"), consummated a purchase agreement with AMVESCAP PLC pursuant
to which AMVESCAP PLC acquired LGT's Asset Management Division, which included
Chancellor LGT and certain other affiliates. Also, as of the close of business
May 29, 1998, A I M Distributors, Inc. ("AIM Distributors"), a wholly-owned
subsidiary of the Manager, became the Fund's distributor, and the Trust was
reorganized from a Massachusetts business trust into a Delaware business trust.
Finally, as of the close of business on September 4, 1998, A I M Fund Services,
Inc. ("AFS"), an affiliate of the Manager and AIM Distributors, replaced GT
Global Investor Services, Inc. ("GT Services") as the transfer agent of the
Fund.
 
AIM Distributors serves as the Fund's distributor. For the period ended May 29,
1998, GT Global, Inc. ("GT Global"), an affiliate of the investment sub-advisor,
served as the Fund's distributor.
 
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. AIM Distributors 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 year ended December 31, 1998, AIM Distributors
retained $5,203 of such sales charges. Purchases of Class A shares exceeding
$1,000,000 may be subject to a contingent deferred sales charge ("CDSC") upon
redemption, in accordance with the Fund's current prospectus. There were no
CDSC's collected for Class A for the year ended December 31,1998. In addition,
AIM Distributors 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, AIM Distributors from its own resources pays
 
                                       11
<PAGE>
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. During the year ended December
31, 1998, AIM Distributors collected such CDSCs in the amount of $77,258. In
addition, AIM Distributors makes ongoing shareholder servicing and trail
commission payments to dealers whose clients hold Class B shares.
 
Class C shares are not subject to initial sales charges. When Class C shares are
sold, AIM Distributors from its own resources pays commissions to dealers
through which the sales are made. Certain redemptions of Class C shares made
within one year of purchase are subject to CDSCs, in accordance with the Fund's
current prospectus. During the year ended December 31, 1998, AIM Distributors
collected such CDSCs in the amount of $208. In addition, AIM Distributors makes
ongoing shareholder servicing and trail commission payments to dealers whose
clients hold Class B shares.
 
For the period ended May 29, 1998, pursuant to the then effective separate
distribution plans adopted under the 1940 Act Rule 12b-1 by the Trust's Board of
Trustees with respect to the Fund's Class A shares ("Class A Plan"), Class B
shares ("Class B Plan") and Class C shares ("Class C"), the Fund reimbursed GT
Global for a portion of its shareholder servicing and distribution expenses.
Under the Class A Plan, the Fund was permitted to 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 was permitted to 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 was reimbursed under
the Class A Plan would have been incurred within one year of such reimbursement.
 
For the period ended May 29, 1998, pursuant to that Class B Plan and Class C
Plan, the Fund was permitted to pay GT Global a service fee at the annualized
rate of up to 0.25% of the average daily net assets of the Fund's Class B and
Class C shares for GT Global's expenditures incurred in servicing and
maintaining shareholder accounts, and was permitted to pay GT Global a
distribution fee at the annualized rate of up to 0.75% of the average daily net
assets of the Fund's Class B and Class C shares for GT Global's expenditures
incurred in providing services as distributor. Expenses incurred under the Class
B Plan and Class C Plan in excess of 1.00% annually were permitted to be carried
forward for reimbursement in subsequent years as long as that Plan continues in
effect.
 
Effective as of the close of business May 29, 1998, pursuant to Rule 12b-1 under
the 1940 Act, the Trust's Board of Trustees has adopted a Master Distribution
Plan applicable to the Fund's Class A and Class C shares (the "Class A and Class
C Plan") and Class B shares ("Class B Plan"), pursuant to which a Fund
compensates AIM Distributors for the purpose of financing any activity that is
intended to result in the sale of Class A, Class B, and Class C shares of the
Funds. Under the Class A and Class C Plan, a Fund compensates AIM Distributors
at the annualized rate of 0.50% of the average daily net assets of the Fund's
Class A shares and an aggregated amount of 1.00% of the average daily net assets
of Class C shares of the Fund. The Fund, pursuant to the Fund's Class B Plan,
compensates AIM Distributors at an annualized rate of 1.00% of the average daily
net assets of the Fund's Class B shares. Of these amounts, the Fund may pay a
service fee of 0.25% of the average daily net assets of the Class A or Class B
shares to selected dealers and financial institutions who furnish continuing
personal shareholder services to their customers who purchase and own the
appropriate class of shares of the Fund. Any amounts not paid as a service fee
under the Plans would constitute an asset-based sales charge.
 
The Manager is 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 AFS, 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 AIM
Distributors 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.
 
Effective as of the close of business September 4, 1998, the Fund, pursuant to a
transfer agency and service agreement, has agreed to pay AFS an annualized fee
of $24.85 per shareholder accounts that are open during any monthly year (this
fee includes all out-of-pocket expenses), and an annualized fee of $0.70 per
shareholder account that is closed during any monthly year. Both fees shall be
billed by AFS monthly in arrears on a prorated basis of 1/12 of the annualized
fee for all such accounts.
 
For the period January 1, 1998 to September 4, 1998, GT Services, an affiliate
of the Manager and AIM Distributors, was the transfer agent of the Fund. For
performing shareholder servicing, reporting, and general transfer agent
services, GT Services received 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
was also reimbursed by the Fund for its out-of-pocket expenses for such items as
postage, forms, telephone charges, stationery and office supplies.
 
Subject to the receipt of a pending exemptive order from the Securities and
Exchange Commission, the Trust will pay each of its Trustees who is not an
employee, officer or director of the Manager or AIM Distributors $5,000 per year
plus $300 for each meeting of the board or any committee thereof attended by the
Trustee. Until such order is received, the Manager pays the trustees such fees.

                                   REPORT OF
                            INDEPENDENT ACCOUNTANTS
 
- --------------------------------------------------------------------------------
 
To the Shareholders of AIM Global Trends Fund (formerly AIM New Dimension Fund
and prior to that GT Global New Dimension Fund) and Board of Trustees of AIM
Series Trust (formerly GT Global Series Trust):
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the AIM Global Trends Fund at
December 31, 1998, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

HOW AIM MAKES INVESTING EASY FOR YOU

- --     LOW INITIAL INVESTMENT. You can get your investment program started 
       for as little as $500. Subsequent investments can be made for only $50.

- --     AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR CAPITAL GAINS. 
       Distributions may be received in cash or reinvested in the Fund free 
       of charge. Over time, the power of compounding can significantly 
       increase the value of your assets.

- --     AUTOMATIC INVESTMENT PLAN. You may build your investment by regularly 
       purchasing additional shares. Pre-authorized checks for $50 or more 
       can be drafted monthly from your personal checking account.

- --     EASY ACCESS TO YOUR MONEY. Your shares may be redeemed at net asset 
       value any day the New York Stock Exchange is open. The price of shares 
       sold may be more or less than their original cost, depending on market 
       conditions.

- --     SYSTEMATIC WITHDRAWAL PLAN. You may elect to receive checks of at 
       least $50 monthly or quarterly through a systematic withdrawal plan.

- --     EXCHANGE PRIVILEGE. As your goals change, you may exchange all or part 
       of your assets for those of other funds within the same share class of 
       The AIM Family of Funds-Registered Trademark-. The exchange privilege 
       may be modified or discontinued for any of the AIM funds. Certain 
       restrictions apply.

- --     RETIREMENT PLANS. You may purchase shares of an AIM fund for your 
       Individual Retirement Account (IRA), Roth IRA, or any other type of 
       retirement plan, and earn tax-deferred dollars for your retirement.

- --     TOLL-FREE ACCESS. Current shareholders can call our AIM Investor Line 
       at 800-246-5463 for 24-hour-a-day account information. Or, of course, 
       you may contact your financial consultant for assistance.
