MESSAGE FROM THE CHAIRMEN

Dear Fellow Shareholder,

We are pleased to send you this semiannual report. In the time since you
received your last report, there have been a few changes. Your Fund is now a
part of The AIM Family of Funds-Registered Trademark- and has adopted the AIM
name. Thanks to a vote of approval by GT Global shareholders, A I M Advisors,
Inc. became the new investment advisor to GT Global Funds, effective June 1,
1998. 

We believe you'll enjoy many advantages as a member of The AIM Family of
Funds-Registered Trademark-. You'll have access to a greater variety of
investment choices, and you'll benefit from AIM's commitment to excellence in
shareholder service. Most of all, you'll be part of an expanded fund family that
is one of the largest and most respected in the industry. 

Though the funds are wearing a new name, your investments will continue to seek
their stated objectives and receive expert, professional management. In the
report that follows you'll find commentary from managers you know, with the
depth of coverage you've come to expect.

If you have any questions about your account, you can continue to call 
800-223-2138 for information, service and transactions. Fund and account
information can also be found on the GT Global Website (www.gtglobal.com). These
sources will be available to you until September 1998. At that time, GT Global
accounts will be fully integrated into The AIM Family of Funds-Registered
Trademark-, and you will have received additional information from AIM.

Thank you for your past support of GT Global Funds. AIM is looking forward to
continuing a satisfying relationship with you and helping you reach your
financial goals.

Sincerely,

/s/ William J. Guilfoyle                          /s/ Charles T. Bauer

AIM DEVELOPING MARKETS FUND
PERFORMANCE SUMMARY


ABOUT THE PERFORMANCE SUMMARY

The G.T. Global Developing Markets Fund, Inc. (the "Predecessor Fund"), a
closed-end fund whose single class of shares traded on the New York Stock
Exchange, converted to an open-end fund on October 31, 1997, at which time
shareholders of the Predecessor Fund received Class A shares of the new Fund.
This enabled shareholders to realize the Predecessor Fund's discount to net
asset value. Fees and expenses of the new Fund differ from those of the
Predecessor Fund. Performance data shown for the period January 1, 1997 to
October 31, 1997 are based on performance and expenses of the Predecessor Fund.
As of November 1, 1997, performance is affected by expenses that the Fund incurs
as an open-ended Fund.

INTERVIEW WITH THE MANAGEMENT TEAM

Q    HOW DID THE FUND PERFORM?

A    For the six-month period to April 30, 1998, 
sentiment toward many emerging equity markets continued to suffer from the Asian
crisis, beginning with devaluation of the Thai baht in July 1997. The fall in
oil prices in March of this year also contributed to the softness of several
emerging markets, including Russia, Mexico and Venezuela. 

Against this backdrop, the Fund's Class A shares returned a total of 3.68%
(-1.27% including the maximum 4.75% sales charge); total return for the Fund's
Class B Shares was 3.36% (-1.24% including the maximum 5% contingent deferred
sales charge). The International Finance Corporation (IFC) Investable Composite
Index (5) returned 3.66% and the J.P. Morgan Emerging Markets Bond Index (EMBI)
Plus (6) returned a total of 14.28% over the same period.

On a country selection basis, the Fund performed well against the IFC Investable
Composite Index, with our underweighted positions in Malaysia and Indonesia
contributing significantly to Fund performance. Security selection in Taiwan was
also overwhelmingly positive. However, stock selection overall, and in South
Africa in particular, caused the Fund to lag the index. 

The Fund's bond portion performed relatively in line with the J.P. Morgan EMBI
Plus. As a region, Latin America performed fairly well, with the Fund's
Brazilian fixed income position returning 13.97%. Russia, the Fund's largest
bond position (6% at the end of April), also contributed significantly to Fund
performance, returning 19.60%. The total percentage of the Fund's net assets
allocated to fixed income stood at 17% at April 30, which caused the Fund to
underperform the J.P Morgan EMBI Plus on an absolute basis, as emerging market
bonds outperformed equities.

Q    WHAT COMPANIES MOST IMPACTED THE FUND'S PERFORMANCE?

A    In this difficult environment, a few select companies performed well,
including Asustek Computer of Taiwan, Brazil's Telebras and Telefonos de Mexico.
Asustek benefited from strength in the electronics sector and a strong
competitive position.  Telebras and Telefonos de Mexico-two of the most liquid
stocks in Latin America-recovered from their October lows as funds returned to
emerging markets.

Notable disappointments included South Africa's Iscor-a steel producer-and other
resource based stocks which have been hit by significant downward revisions in
growth and, therefore, forecast commodity prices.

Q    WHAT EFFECT HAVE EVENTS IN ASIA HAD ON EMERGING MARKET DEBT?

A    The Asian financial crisis has cast a pall over most emerging bond markets.
As expected, established economies were able to weather the Asian situation with
aplomb. How emerging markets will fare going forward remains to be seen.
Relatively low global inflation and falling bond yields in established markets
have suppressed investors' exuberance for emerging market debt. Investors
apparently remember the apex of the Asian crisis last year, when emerging 

INVESTMENT OBJECTIVE

The Fund primarily seeks long-term capital appreciation and secondarily seeks
income, to the extent consistent with seeking capital appreciation. While a
majority of its assets are ordinarily invested in developing market equity
securities, the Fund may also invest in developing market debt securities,
making it possible to shift resources where we perceive opportunities are the
most promising.


                                                                    CONTINUED P4

markets yield spreads more than doubled relative to U.S. Treasuries. 

The six-month period ending April 1998 encompasses the huge market sell-off in
the days following October 1997 and the subsequent recovery in the first four
months of 1998.  We feel this particular period offers a distorted view of the
returns investors have been experiencing. Valuations at the end of October 1997
represented prices close to the lows experienced during the Asian sell-off. 
Conversely, valuations at the end of April 1998 represented levels at the high
end for the period. Following the end of the period, the market has since
corrected and is currently (mid-June) near the lows of the Asian crisis.

We feel emerging market debt continues to suffer from the lingering effect of
the Asian meltdown. Latin America, for example, is faced with lower commodity
prices and increased export competition that is resulting in deteriorating trade
accounts for most Latin countries and making exchange rates more difficult to
control. 

Q    HOW IS THE FUND POSITIONED RELATIVE TO THE IFC INVESTABLE COMPOSITE INDEX?

A    We remain underweighted in most Asian emerging markets.  We are
significantly overweighted against the index in only a few emerging
markets--Egypt, Turkey, Israel and Hungary.  We feel some emerging markets are
overly exposed to weakness in the price of oil and other commodities.  Others,
particularly in Europe, appear very expensive.  Above all, the problems of the
newly industrialized countries in East Asia continue to overshadow most emerging
markets. At the end of April, the Fund was overweighted in the EMEA region (the
emerging markets of Europe, the Middle East and Africa), underweighted in Asia
and in line with the index weighting in Latin America.

Within EMEA, we added to our positions in Turkey, Israel, Greece and Hungary
over the six-month period. At the same time, we reduced exposure to South
Africa, to a considerably underweighted position relative to the index. We also
sold off a significant number of our Asian holdings, including those in
Indonesia, Thailand and Hong Kong. We substantially reduced exposure to Hong
Kong-listed red-chip stocks. Among our Latin American holdings, we supplemented
our investments in Argentina, Brazil, Mexico and Peru at the expense of Chile. 

The most important underweighted positions include Indonesia, South Korea,
Malaysia, Thailand and Taiwan. We see insufficient progress toward restructuring
and recapitalization of the banking sector, with authorities continuing to
sanction non-market based solutions. In South Korea, major corporations remain
in business even though bankrupt, the Malaysian government has financially
rescued politically well-connected companies, and the political situation in
Indonesia remains volatile. We are underweighted in Taiwan despite its
relatively stable economic and political outlook because we feel valuations are
too demanding. 

Additionally, we have zero exposure to Venezuelan equities, which are especially
vulnerable to any further weakness in the price of oil; to the Czech Republic,
where political risks are excessive; and to Portugal, which appears very
overvalued. 

Q    WHAT DO YOU LIKE ABOUT THE EQUITY MARKETS OF EMEA?

A    Although our outlook for many of these markets continues to be overshadowed
by events in Asia, we find some selected opportunities in the region.  In
particular, we favor Egypt, Israel and Hungary.

In Egypt, interest rates have continued to edge lower, largely on the back of a
slight fall in inflation. We believe valuations remain attractive, and economic
reform and inflows of foreign capital could boost consumption and investment.

We believe falling inflation in Israel could prompt authorities to cut interest
rates further. Both economic fundamentals and stock valuations are attractive,
leading us to overweight the Israeli market.



                                                                    CONTINUED P5

INTERVIEW WITH THE MANAGEMENT TEAM   CONTINUED


Our outlook for Hungary remains positive. The commitment of the Hungarian
authorities to financial stability and economic austerity has resulted in a
significant rerating of the domestic stock market. Its status as a relatively
safe haven subsequent to the global equity market turbulence in October 1997 has
produced substantial capital inflows and driven the market to record levels.
Fundamentally, the market continues to impress, and we are forecasting
significantly higher export-fueled growth this year. While we currently expect
to remain overweighted, we will watch for any signs of overheating.

Q    WHAT ARE YOUR EXPECTATIONS OF SOUTH AMERICAN EQUITY MARKETS?

A    Weakness in the price of oil has led to a tightening in Mexico's fiscal
policy, which we believe may serve to dampen domestic demand.  Moreover, trade
accounts have deteriorated somewhat and, as a consequence, the peso may soften.
Against these negative factors, inflation has stabilized, interest rates could
decline from here, and we are able to identify a range of attractive stocks. We
remain slightly underweighted.

We are underweighted in Argentina's major oil stocks, which account for about
43% of the stock market's capitalization. However, we are overweighted in
banks and other plays on domestic demand, which remains firm.

We believe Brazil's economic growth is likely to be constrained by the doubling
in interest rates, to around 40%, and by the latest fiscal package. Much of the
good news about the economic reform program has already been discounted by the
market. Further progress may also be difficult following the deaths of two key
political supporters of President Cardoso.  Although we are still overweighted
relative to the index, we have begun to trim our positions somewhat. In our
stock selection, we are concentrating on  privatization plays.

Among the smaller markets, we are overweighted in Peru. Even though El Nino and
falling metal prices have had a severe impact on the important fishing and
mining industries, we believe equity valuations are attractive. However, we are
avoiding Colombia, where the economy is still weak and where political
instability remains a key issue. 

We are also avoiding Venezuela, where we think the fall in the price of oil will
contribute to an economic slowdown and, possibly, to currency weakness. In
Chile, we believe valuations are beginning to appear attractive and that the
stock market may have discounted the impact of problems in East Asia 
on Chile's exports, along with the recent rise in interest rates.  

Q    WHY DID YOU REDUCE THE FUND'S EQUITY EXPO SURE TO ASIA?

A    We believe the recent optimism that produced strong rallies in a number of
these stock markets over the past three to four months is misplaced.  In our
opinion, the environment in Asia remains very challenging, and we continue to
believe regional stock markets will remain volatile. 

Thanks in part to Japan's worsening problems, economic conditions throughout the
region continue to deteriorate. While additional renegotiations of foreign
currency debt will take place later in 1998, authorities have not moved
sufficiently to recapitalize failed banks in the countries most affected by
financial crises over the last year.  Above all, the economic problems and
political instability of Indonesia are likely to dampen investment sentiment
toward other ASEAN countries, South Korea and Hong Kong for some time.  

Q    WHAT IS YOUR POSITION ON SOUTH AFRICA?

A    We have continued to realize profits in South African equities and have
sold off our debt holdings entirely. Short-term inflows of capital have boosted
money supply growth, with the consequence that bond yields have risen. Most
analysts are recognizing weakness in the economy and revising down their
earnings forecasts. We feel equity valuations are demanding.

INTERVIEW WITH THE MANAGEMENT TEAM   CONTINUED

Q    RUSSIA CONTINUES TO BE A SIGNIFICANT FUND HOLDING AT 9.1%.  ARE YOU
     CONCERNED ABOUT RECENT MARKET WEAKNESS?

A    We continue to believe in Russia's merits as a long-term holding. However,
we have a number of concerns about Russia, not the least of which is the poor
fiscal situation and large amount of short-term foreign capital in local
markets. Nonetheless, the Russian government is expected to reach an agreement
with the IMF in the next few weeks, and the new government appears proactive and
committed to reform. While we expect the situation in Russia to remain volatile,
we are positive over the short term and will continue to monitor events closely.

Q    DO YOU STILL CONSIDER EMERGING MARKET DEBT ATTRACTIVE AS AN ASSET CLASS?

A    We continue to find emerging market debt attractive as an asset class. As
of April 30, 1998, yields are over 250 basis points in excess of U.S. high-yield
bonds, an impressive difference. In addition, emerging markets have historically
offered investors important diversification because of their lower correlation
to other financial asset classes. However, investors should be aware that
investing in emerging markets carries certain additional risks relating to
political uncertainty and currency instability.

To the Shareholders and Board of Directors of AIM Developing Markets Fund
("Fund"):
 
We have audited the accompanying statement of assets and liabilities of AIM
Developing Markets Fund (formerly GT Global Developing Markets Fund), including
the portfolio of investments, as of April 30, 1998, the related statement of
operations for the six months then ended, the statements of changes in net
assets for the six months then ended, for the ten months ended October 31, 1997
and for the year ended December 31, 1996, and the financial highlights for each
of the periods indicated therein. These 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 April
30, 1998, by correspondence with the custodians and brokers. 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 AIM
Developing Markets Fund as of April 30, 1998, the results of its operations for
the six months then ended, the changes in its net assets for the six months then
ended, for the ten months ended October 31, 1997 and for the year ended December
31, 1996, and the financial highlights for each of the periods indicated
therein, in conformity with generally accepted accounting principles.

 (a) Annualized
 (b) Not annualized
 (c) Total investment return does not include sales charges.
 (d) These selected per share data were calculated based upon the average
     shares outstanding during the period.
 (e) These financial highlights provide per share information of G.T.
     Global Developing Markets Fund, Inc. ("Predecessor Fund") (See Note 1
     to Notes to Financial Statements) for the periods up to and including
     October 31, 1997. The fees and expenses of the Fund differ from those
     of the Predecessor Fund.
{/\} Net investment income per share reflects an interest payment received
     from the conversion of Vnesheconombank loan agreements. Without such a
     payment net investment would have been $0.09, $0.07 and $0.13 per
     share for Class A, B, and Advisor, respectively.
  *  Before reimbursement by Chancellor LGT Asset Management, Inc., the net
     investment income per share would have been reduced by $0.03 for Class
     A, B, and Advisor.
  +  All capital shares issued and outstanding October 31, 1997 were
     reclassified as Class A shares.
 ++  Commencing November 1, 1997, the Fund began offering Class B and
     Advisor Class shares.
+++  Portfolio turnover rate, average commission rate, and ratio of
     interest expense to average net assets are calculated on the basis of
     the Fund as whole without distinguishing between the classes of shares
     issued.
N/A  Not Applicable.

The following Notes to Financial Statements are for the period ending April 30,
1998, and unless otherwise indicated reflect facts as of that date. Please see
"Note 6 -- Subsequent Events" for a discussion of certain changes which took
place after April 30, 1998.
 
1. SIGNIFICANT ACCOUNTING POLICIES (SEE ALSO NOTE 6)
 
GT Global Developing Markets Fund ("Fund") is a separate series of G.T.
Investment Funds, Inc. ("Company"). Effective June 1, 1998, the Company was
renamed AIM Investment Funds, Inc. and the Fund was renamed AIM Developing
Markets Fund. The Company is organized as a Maryland corporation and is
registered under the Investment Company Act of 1940, as amended ("1940 Act"), as
an open-end management investment company. The Company has thirteen series of
shares in operation, each series corresponding to a distinct portfolio of
investments.
 
On October 31, 1997, at the close of business, the Fund acquired the assets and
assumed the liabilities of G.T. Global Developing Markets Fund, Inc., a Maryland
corporation registered under the 1940 Act as a non-diversified closed-end
management investment company ("Predecessor Fund"), in exchange for Class A
shares of the Fund in a tax-free reorganization of the Predecessor Fund.
Shareholders of the Predecessor Fund approved the reorganization on October 20,
1997. Prior to October 28, 1997 the Closed-End Fund's shares traded on the New
York Stock Exchange.
 
Commencing November 1, 1997, the Fund began to offer Class A, Class B, and
Advisor Class shares, each of which has equal rights as to assets and voting
privileges except that 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, and the common expenses 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, and may differ in its transfer agent,
registration, and certain other class-specific fees and 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 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 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.
 
Equity securities are valued at the last sale price on the exchange on which
such securities are traded or on the principal over-the-counter market on which
such securities are traded, as of the close of business on the day the
securities are being valued, or, lacking any sales, at the last available bid
price. In cases where securities are traded on more than one exchange, the
securities are valued on the exchange determined by Chancellor LGT Asset
Management, Inc. (the "Manager") to be the primary market.
 
Fixed income investments are valued at the mean of representative quoted bid and
asked prices for securities or, if such prices are not available, at prices for
securities of comparative maturity, quality and type; however, when the Manager
deems it appropriate, prices obtained for the day of valuation from a bond
pricing service will be used. Short-term investments with a maturity of 60 days
or less are valued at amortized cost, adjusted for foreign exchange translation
and market fluctuation, if any.
 
Investments for which market quotations are not readily available (including
restricted securities which are subject to limitations on their sale) are valued
at fair value as determined in good faith by or under the direction of the
Fund's Board of Directors.
 
Portfolio securities which are primarily traded on foreign exchanges are
generally valued at the preceding closing values of such securities on their
respective exchanges, and those values are then translated into U.S. dollars at
the current exchange rates, except that when an occurrence subsequent to the
time a value was so established is likely to have materially changed such value,
then the fair value of those securities will be determined by consideration of
other factors by or under the direction of the Fund's Board of Directors.
 
(B) FOREIGN CURRENCY TRANSLATION
The accounting records of the Fund are maintained in U.S. dollars. The market
values of foreign securities, currency holdings, other assets and liabilities
are recorded in the books and records of the Fund after translation to U.S.
dollars based on the exchange rates on that day. The cost of each security is
determined using historical exchange rates. Income and withholding taxes are
translated at prevailing exchange rates when earned or incurred.
 
The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
existing from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.
 
Reported net realized foreign exchange gains and losses arise from sales and
maturities of short-term investments, forward foreign currency contracts, sales
of foreign currencies, currency gains or
 
                                      F22
<PAGE>
                          AIM DEVELOPING MARKETS FUND
                  (FORMERLY GT GLOBAL DEVELOPING MARKETS FUND)
 
losses realized between the trade and settlement dates on securities
transactions, and the differences between the amounts of dividends, interest,
and foreign withholding taxes recorded on the Fund's books and the U.S. dollar
equivalent of the amounts actually received or paid. Net unrealized foreign
exchange gains and losses arise from changes in the value of assets and
liabilities other than investments in securities at year end, resulting from
changes in exchange rates.
 
(C) 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.
 
(D) FORWARD FOREIGN CURRENCY CONTRACTS
A forward foreign currency contract ("Forward Contract") is an agreement between
two parties to buy and sell a currency at a set price on a future date. The
market value of the Forward Contract fluctuates with changes in currency
exchange rates. The Forward Contract is marked-to-market daily and the change in
market value is recorded by the Fund as an unrealized gain or loss. When the
Forward Contract is closed, the Fund records a realized gain or loss equal to
the difference between the value at the time it was opened and the value at the
time it was closed. The Fund could be exposed to risk if a counterparty is
unable to meet the terms of a contract or if the value of the currency changes
unfavorably. The Fund may enter into Forward Contracts in connection with
planned purchases or sales of securities or to hedge against adverse
fluctuations in exchange rates between currencies.
 
(E) OPTION ACCOUNTING PRINCIPLES
When the Fund writes a call or put option, an amount equal to the premium
received is included in the Fund's "Statement of Assets and Liabilities" as an
asset and an equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current market value of the option. The current
market value of an option listed on an exchange is valued at its last bid price,
or, in the case of an over-the-counter option, is valued at the average of the
last bid prices obtained from brokers, unless a quotation from only one broker
is available, in which case only that broker's price will be used. If an option
expires on its stipulated expiration date or if the Fund enters into a closing
purchase transaction, a gain or loss is realized without regard to any
unrealized gain or loss on the underlying security, and the liability related to
such option is extinguished. If a written call option is exercised, a gain or
loss is realized from the sale of the underlying security and the proceeds of
the sale are increased by the premium originally received. If a written put
option is exercised, the cost of the underlying security purchased would be
decreased by the premium originally received. The Fund can write options only on
a covered basis, which, for a call, requires that the Fund hold the underlying
security, and, for a put, requires the Fund to set aside cash, U.S. government
securities or other liquid securities in an amount not less than the exercise
price or otherwise provide adequate cover at all times while the put option is
outstanding. The Fund may use options to manage its exposure to the stock and
bond markets and to fluctuations in currency values or interest rates.
 
The premium paid by the Fund for the purchase of a call or put option is
included in the Fund's "Statement of Assets and Liabilities" as an investment
and subsequently "marked-to-market" to reflect the current market value of the
option. If an option which the Fund has purchased expires on the stipulated
expiration date, the Fund realizes a loss in the amount of the cost of the
option. If the Fund enters into a closing sale transaction, the Fund realizes a
gain or loss, depending on whether proceeds from the closing sale transaction
are greater or less than the cost of the option. If the Fund exercises a call
option, the cost of the securities acquired by exercising the call is increased
by the premium paid to buy the call. If the Fund exercises a put option, it
realizes a gain or loss from the sale of the underlying security, and the
proceeds from such sale are decreased by the premium originally paid.
 
The risk associated with purchasing options is limited to the premium originally
paid. The risk in writing a call option is that the Fund may forego the
opportunity of profit if the market value of the underlying security or index
increases and the option is exercised. The risk in writing a put option is that
the Fund may incur a loss if the market value of the underlying security or
index decreases and the option is exercised. In addition, there is the risk the
Fund may not be able to enter into a closing transaction because of an illiquid
secondary market.
 
(F) FUTURES CONTRACTS
A futures contract is an agreement between two parties to buy and sell a
security at a set price on a future date. Upon entering into such a contract the
Fund is required to pledge to the broker an amount of cash or securities equal
to the minimum "initial margin" requirements of the exchange on which the
contract is traded. Pursuant to the contract, the Fund agrees to receive from or
pay to the broker an amount of cash equal to the daily fluctuation in value of
the contract. Such receipts or payments are known as "variation margin" and are
recorded by the Fund as unrealized gains or losses. When the contract is closed,
the Fund records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the time it was
closed. The potential risk to the Fund is that the change in value of the
underlying securities may not correlate to the change in value of the contracts.
The Fund may use futures contracts to manage its exposure to the stock and bond
markets and to fluctuations in currency values or interest rates.
 
(G) SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME
Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). The cost of securities sold is determined on a first-in,
first-out basis, unless otherwise specified. Dividends are recorded on the
ex-dividend date. Interest income is recorded on the accrual basis. Where a high
level of uncertainty exists as to collection of income on securities, income is
recorded net of all
 
                                      F23
<PAGE>
                          AIM DEVELOPING MARKETS FUND
                  (FORMERLY GT GLOBAL DEVELOPING MARKETS FUND)
 
withholding tax with any rebate recorded when received. The Fund may trade
securities on other than normal settlement terms. This may increase the market
risk if the other party to the transaction fails to deliver and causes the Fund
to subsequently invest at less advantageous prices.
 
(H) PORTFOLIO SECURITIES LOANED
At April 30, 1998, stocks with an aggregate value of approximately $13,962,416
were on loan to brokers. The loans were secured by cash collateral of
$14,552,194 received by the Fund. For international securities, cash collateral
is received by the Fund against loaned securities in an amount at least equal to
105% of the market value of the loaned securities at the inception of each loan.
This collateral must be maintained at not less than 103% of the market value of
the loaned securities during the period of the loan. For domestic securities,
cash collateral is received by the Fund against loaned securities in an amount
at least equal to 102% of the market value of the loaned securities at the
inception of each loan. This collateral must be maintained at not less than 100%
of the market value of the loaned securities during the period of each loan. The
cash collateral is invested in a securities lending trust which consists of a
portfolio of high quality short duration securities whose average effective
duration is restricted to 120 days or less. For the six months ended April 30,
1998, the Fund received securities lending income of $155,608.
 
(I) 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, and unrealized appreciation of securities held, or excise tax on income
and capital gains. The Fund currently has a capital loss carryforward of
$54,472,976 which expires in 2003.
 
(J) 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.
 
(K) DEFERRED ORGANIZATIONAL EXPENSES
Expenses incurred by the Fund in connection with its organization, its
registration with the Securities and Exchange Commission and with various states
aggregated $353,775. These expenses are being amortized on a straightline basis
over a five-year period.
 
(L) FOREIGN SECURITIES
There are certain additional considerations and risks associated with investing
in foreign securities and currency transactions that are not inherent in
investments of domestic origin. The Fund's investments in emerging market
countries may involve greater risks than investments in more developed markets
and the prices of such investments may be volatile. These risks of investing in
foreign and emerging markets may include foreign currency exchange rate
fluctuations, perceived credit risk, adverse political and economic developments
and possible adverse foreign government intervention.
 
(M) INDEXED SECURITIES
The Fund may invest in indexed securities whose value is linked either directly
or indirectly to changes in foreign currencies, interest rates, equities,
indices, or other reference instruments. Indexed securities may be more volatile
than the reference instrument itself, but any loss is limited to the amount of
the original investment.
 
(N) RESTRICTED SECURITIES
The Fund is permitted to invest in privately placed restricted securities. These
securities may be resold in transactions exempt from registration or to the
public if the securities are registered. Disposal of these securities may
involve time-consuming negotiations and expense, and prompt sale at an
acceptable price may be difficult.
 
(O) SECURITIES PURCHASED ON A WHEN-ISSUED OR FORWARD COMMITMENT BASIS
The Fund may trade securities on a when-issued or forward commitment basis, with
payment and delivery scheduled for a future date. These transactions are subject
to market fluctuations and are subject to the risk that the value at delivery
may be more or less than the trade date purchase price. Although the Fund will
generally purchase these securities with the intention of acquiring such
securities, they may sell such securities before the settlement date. These
securities are identified on the accompanying Portfolio of Investments. The Fund
has purchased and sold when-issued securities during the period and has set
aside liquid securities as collateral for these commitments.
 
(P) LINE OF CREDIT
The Fund, along with certain other funds advised and/or administered by the
Manager ("GT Funds"), has a line of credit with each of 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 each Fund's total assets. On
April 30, 1998, the Fund had no loans outstanding.
 
For the six months ended April 30, 1998, the weighted average outstanding daily
balance of bank loans (based on the number of days the loans were outstanding)
for the Fund was $7,671,408, with a weighted average interest rate of 6.29%.
Interest expense for the Fund for the six months ended April 30, 1998 was
$210,460. Other interest expense charges amounted to $49,556.
 
2. RELATED PARTIES (SEE ALSO NOTE 6)
For the period ended April 30, 1998, Chancellor LGT Asset Management, Inc. was
the Fund's investment manager and administrator. The Fund pays the Manager
investment management and administration fees at the annualized rate of 0.975%
on the first $500 million of average daily net assets of the Fund; 0.95% on the
 
                                      F24
<PAGE>
                          AIM DEVELOPING MARKETS FUND
                  (FORMERLY GT GLOBAL DEVELOPING MARKETS FUND)
 
next $500 million; 0.925% on the next $500 million and 0.90% on amounts
thereafter. These fees are computed daily and paid monthly.
 
For the period ended April 30, 1998, 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.
 
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 six months ended April 30, 1998, GT Global did not
retain any 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 did not collect
CDSCs for the six months ended April 30, 1998. 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 six months ended April 30, 1998, GT Global did not collect
any CDSCs. In addition, GT Global makes ongoing shareholder servicing and trail
commission payments to dealers whose clients hold Class B shares.
 
Pursuant to the then effective separate distribution plans adopted under 1940
Act Rule 12b-1 by the Company's Board of Directors with respect to the Fund's
Class A shares ("Class A Plan") and Class B shares ("Class B Plan"), the Fund
reimbursed GT Global for a portion of its shareholder servicing and distribution
expenses. Under that 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 April 30, 1998, pursuant to that Class B 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 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 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 were permitted to be
carried forward for reimbursement in subsequent years as long as that Plan
continued in effect.
 
The Manager and GT Global voluntarily undertook to limit the Fund's expenses
(exclusive of brokerage commissions, taxes, interest, and extraordinary
expenses) to the maximum annual rate of 2.00%, 2.50%, and 1.50% of the average
daily net assets of the Fund's Class A, Class B, and Advisor Class shares,
respectively. If necessary, this limitation will be effected by the waivers by
the Manager of investment management and administration fees, waivers by GT
Global of payments under the Class A Plan and/or Class B Plan and/or
reimbursements by the Manager or GT Global of portions of the Fund's other
operating expenses.
 
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 also is reimbursed by the
Fund for its out-of-pocket expenses for such items as postage, forms, telephone
charges, stationery and office supplies.
 
The Manager is the pricing and accounting agent for the fund. The monthly fee
for these services to the Manager is a percentage, not to exceed 0.03% annually,
of the Fund's average daily net assets. The annual fee rate is derived by

On May 29, 1998, Liechtenstein Global Trust ("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. As a result of this transaction, Chancellor LGT was
renamed INVESCO (NY), Inc. and is now an indirect wholly-owned subsidiary of
AMVESCAP PLC. In connection with this transaction, A I M Advisors, Inc. ("AIM"),
an indirect wholly-owned subsidiary of AMVESCAP PLC, became the investment
adviser and administrator of the Fund and INVESCO (NY), Inc. became the
sub-adviser and sub-administrator of the Fund. In addition, A I M Distributors,
Inc. replaced GT Global, Inc. as the Fund's principal underwriter, and the Fund
became subject to compensation-type Rule 12b-1 plans of distribution, which
replaced the Fund's former reimbursement-type Rule 12b-1 plans of distribution.
All of the changes became effective as of the close of business on May 29, 1998.
