                     SEMIANNUAL REPORT / CHAIRMAN'S LETTER

                   Dear Fellow Shareholder:

                   When we started AIM in 1976, we had only a table, two chairs
   [PHOTO OF       and a telephone. At the time, Bob Graham, Gary Crum and I
   Charles T.      had the idea of creating a mutual fund company that put
     Bauer,        people first. Our slogan, "people are the product," means
   Chairman of     that people--our employees and our investors--are our
  the Board of     company.
    THE FUND           Almost a quarter-century later, we've grown to more than
  APPEARS HERE]    seven million investors, $176 billion in assets under
                   management and 53 retail funds. Over that time, the industry
   [PHOTO OF       as a whole has grown from $51 billion in assets to more than
   Robert H.       $7 trillion today. I never dreamed we would see such
    Graham,        phenomenal growth. You are the main reason for our success
  APPEARS HERE]    and I want you to know how much I appreciate your loyalty
                   and trust over the past 24 years.
                       Usually in this letter I review market activity during
                   the period covered by the report. This time, I'd just like
to say thank you. I am retiring as chairman of the AIM Funds effective
September 30, and as chairman of AIM effective December 31, 2000. Bob Graham,
whose picture appears under mine, will succeed me as AIM's chairman and
chairman of the AIM Funds. Gary Crum will remain president of A I M Capital
Management, Inc., leading our investment division. I am enormously proud to
leave AIM in such capable hands.
    I'm also very proud of our team of employees, now more than 2,300 strong.
Because of their collective commitment to excellence and ethical business
practices, AIM has earned the trust of investors and financial advisors alike.
And every employee, from portfolio managers to client services representatives,
is dedicated to serving our shareholders.
    Rest assured that nothing at AIM will change because of my retirement. You
can still depend on this company to manage your money responsibly and provide
you with top-notch service. As chairman of AIM and chairman of the AIM Funds,
Bob is committed to preserving the things that have made AIM great in the past
and positioning it to succeed in the future. And Gary is dedicated to

AIM.

activity, how they have managed your fund over the past six months and their

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW

AIM CHARTER FUND WEATHERS MARKET VOLATILITY

THE STOCK MARKET ENDED 1999 STRONG BUT EXPERIENCED SOME BUMPS IN THE FIRST
MONTHS OF 2000. HOW DID AIM CHARTER FUND PERFORM?
For the six-month reporting period, AIM Charter Fund turned in an excellent
performance. As of April 30, 2000, the fund's Institutional Class shares had
total returns of 17.75%, handily outperforming the S&P 500, which had a
six-month return of 7.18% as of April 30. Net assets in the fund jumped from
$66.8 million to $82.0 million over the reporting period.

WHAT WAS THE MARKET ENVIRONMENT LIKE OVER THE PAST SIX MONTHS?
After an almost uninterrupted rise through the final months of 1999, stocks
began hitting air pockets early in 2000. The large-company-driven Dow hit its
all-time high in mid-January. But a variety of factors converged to shake
market confidence and led to unusual volatility in March and April:

o   U.S. economic growth continued to sizzle, with an annualized growth rate
    above 7% for the fourth quarter of 1999 and above 5% in the first quarter of
    2000. These numbers led many to believe that the Federal Reserve Board (the
    Fed) might implement a larger rate hike in May because its five rate hikes
    since June 1999 did not slow the economy.
o   The March court ruling that Microsoft (a fund holding) had exercised illegal
    monopoly powers cast a pall over the whole technology sector, which was
    already subject to misgivings about the untested heights to which many
    tech-stock values had risen.
o   The Employment Cost Index, which tracks wages and benefits, rose 1.4% in the
    first quarter of 2000, its highest rate in more than 10 years. This hinted
    at rising inflation and jolted investors. Low inflation, combined with
    robust economic growth, has been a major element nurturing the long bull
    market of the `90s.

    For all the headline-making one-day dips and dives among various benchmarks,
it's worth noting that the most widely reported stock indexes all gained during
the six months covered by this report. A great deal of the market's volatility
was confined to some very high-flying tech stocks that saw their values plummet
in the Nasdaq shakeout late in the reporting period. For the most part, company
earnings reports continued to be positive for the first quarter of 2000 across a
broad array of industries, from banking and health care to energy and certain
technologies.

DID YOU MANAGE THE FUND DIFFERENTLY, GIVEN THE MARKET'S VOLATILITY?
We maintained our bias toward larger, more established companies. Our
investment discipline holds that we do not try to time the market by moving in
and out of stocks that go in and out of favor for various reasons. Instead, we
look at companies in terms of their earnings--we focus on companies in growth
industries or sectors and strive to understand what's behind the numbers, what
factors drive a company's earnings and if those factors are sustainable. This
allows us to make buy and sell decisions based on concrete research rather than
market sentiment.

WHAT WERE THE FUND'S TOP SECTOR WEIGHTINGS?
Technology, financials, health care and consumer cyclicals (such as retail
companies) continue to have the heaviest weightings in the fund's portfolio.
Over the past six months, we increased our tech weighting from 32% to 42%,
particularly in the telecommunications-equipment industry. This industry
continues to see tremendous

THE DECLINE OF DIVIDENDS

For the first time in recent history, a quarter of the value of the S&P 500
comes from companies that do not pay dividends. (A dividend is a distribution
of earnings to shareholders.) Twenty years ago, only 2% of the index's value
came from such companies. What has changed?
    A company previously used dividends to convince investors that it was
successful and worthy of investment. Today, many investors consider stocks less
risky than they used to, so the demand for dividends has decreased. Fewer
companies are raising dividends, and increasing numbers of major companies are
not paying them at all.
    What does this mean for AIM Charter Fund? In February, the fund's investment
policy was changed to allow it to respond to market conditions such as this
downward dividend trend. Companies that pay or raise their dividends will
continue to be an important part of the fund's portfolio, but so will
high-quality growth companies.

growth because of the global wireless boom and increased levels of spending by
large corporations positioning themselves to compete in the Internet economy. We
have slightly reduced our weightings in financials and health care to take
advantage of better growth opportunities in the tech sector.

WHAT TECH-RELATED COMPANIES HAVE YOU FAVORED?
The fund owns high-quality, market-leading technology companies that are
generating strong earnings growth ahead of analysts' expectations. For example,
Cisco Systems continues to be a standout holding. Cisco is the world's largest
manufacturer of computer networking equipment--the switches and routers that
direct data across the Internet. In March, Cisco overtook Microsoft as the
world's most valuable company in terms of market capitalization.
    We have increased the fund's position in Finland-based Nokia, which holds
more than a quarter of the world's mobile-phone market. Nokia, which posted a
55% increase in net income for the first quarter of 2000, is touting the
prospects of its next generation of mobile phones, which will receive data and
provide better Internet access.

WHAT OTHER HOLDINGS HAVE BENEFITED THE FUND?
In financials, we own established banks or brokerage firms that have profited
from the strong financial and IPO markets. Morgan Stanley Dean Witter, an
investment-banking and retail-brokerage powerhouse, is a top fund holding. The
firm reported a 50% increase in its fiscal first-quarter income over the
previous year. Of particular benefit to the firm's revenue was its underwriting
of tech-related companies.
    Drug manufacturer Warner-Lambert, our largest holding, continues to see
strong sales of its cholesterol-lowering drug Lipitor. The company reported
positive earnings for the first quarter of 2000, beating analysts' expectations
despite the generally unfavorable performance of the health-care sector.
Warner-Lambert has announced plans to merge with pharmaceutical giant Pfizer, a
move that will create one of the world's largest and fastest-growing drug
companies.

WHAT IS YOUR NEAR-TERM OUTLOOK?
After the close of the reporting period, the Fed raised the federal funds rate
by 0.5% to 6.5%. Recent economic indicators, such as a 30-year low for the U.S.
unemployment rate, led the Fed to be more aggressive in its attempts to fend
off impending inflationary tendencies in the economy. While investors'
inflation fears may cause some short-term market volatility, we believe that
the environment for equities remains largely favorable. Whatever economic
trends surface, we will maintain our philosophy of investing in high-quality
growth companies.

NOTES TO FINANCIAL STATEMENTS

April 30, 2000
(Unaudited)

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Charter Fund (the "Fund") is a series portfolio of AIM Equity Funds, Inc.
(the "Company"). The Company is a Maryland corporation registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of eleven separate portfolios.
The Fund currently offers four different classes of shares: Class A shares,
Class B shares, Class C shares and the Institutional Class. Class A shares are
sold with a front-end sales charge. Class B shares and Class C shares are sold
with a contingent deferred sales charge. Matters affecting each portfolio or
class will be voted on exclusively by the shareholders of such portfolio or
class. The assets, liabilities and operations of each portfolio are accounted
for separately. Information presented in these financial statements pertains
only to the Fund. The Fund's investment objective is growth of capital with a
secondary objective of current income.
    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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.  Security Valuations--A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price as of the close of the
    customary trading session on the exchange where the security is principally
    traded, or lacking any sales on a particular day, the security is valued at
    the closing bid price on that day. Each security reported on the NASDAQ
    National Market System is valued at the last sales price on the valuation
    date or absent a last sales price, at the closing bid price. Debt
    obligations (including convertible bonds) are valued on the basis of prices
    provided by an independent pricing service. Prices provided by the pricing
    service may be determined without exclusive reliance on quoted prices, and
    may reflect appropriate factors such as yield, type of issue, coupon rate
    and maturity date. Securities for which market prices are not provided by
    any of the above methods are valued based upon quotes furnished by
    independent sources and are valued at the last bid price in the case of
    equity securities and in the case of debt obligations, the mean between the
    last bid and asked prices. Securities for which market quotations are not
    readily available or are questionable are valued at fair value as determined
    in good faith by or under the supervision of the Company's officers in a
    manner specifically authorized by the Board of Directors of the Company.
    Short-term obligations having 60 days or less to maturity are valued at
    amortized cost which approximates market value. For purposes of determining
    net asset value per share, futures and option contracts generally will be
    valued 15 minutes after the close of the customary trading session of the
    New York Stock Exchange ("NYSE").
         Generally, trading in foreign securities is substantially completed
    each day at various times prior to the close of the NYSE. The values of such
    securities used in computing the net asset value of the Fund's shares are
    determined as of such times. Foreign currency exchange rates are also
    generally determined prior to the close of the NYSE. Occasionally, events
    affecting the values of such securities and such exchange rates may occur
    between the times at which they are determined and the close of the
    customary trading session of the NYSE which would not be reflected in the
    computation of the Fund's net asset value. If events materially affecting
    the value of such securities occur during such period, then these securities
    will be valued at their fair value as determined in good faith by or under
    the supervision of the Board of Directors.
B.  Securities Transactions and Investment Income--Securities transactions are
    accounted for on a trade date basis. Realized gains or losses on sales are
    computed on the basis of specific identification of the securities sold.
    Interest income is recorded as earned from settlement date and is recorded
    on the accrual basis. Dividend income is recorded on the ex-dividend date.
C.  Distributions--Distributions from income and net realized capital gains, if
    any, are generally paid annually and recorded on ex-dividend date. The Fund
    may elect to use a portion of the proceeds from redemptions as distributions
    for federal income tax purposes.
D.  Federal Income Taxes--The Fund intends to comply with the requirements of
    the Internal Revenue Code necessary to qualify as a regulated investment
    company and, as such, will not be subject to federal income taxes on
    otherwise taxable income (including net realized capital gains) which is
    distributed to shareholders. Therefore, no provision for federal income
    taxes is recorded in the financial statements.
E.  Foreign Currency Translations--Portfolio securities and other assets and
    liabilities denominated in foreign currencies are translated into U.S.
    dollar amounts at date of valuation. Purchases and sales of portfolio
    securities and income items denominated in foreign currencies are translated
    into U.S. dollar amounts on the respective dates of such transactions. The
    Fund does not separately account for that portion of the results of
    operations resulting from changes in foreign exchange rates on investments
    and the fluctuations arising from changes in market prices of securities
    held. Such fluctuations are included with the net realized and unrealized
    gain or loss from investments.
F.  Foreign Currency Contracts--A foreign currency contract is an obligation to
    purchase or sell a specific currency for an agreed-upon price at a future
    date. The Fund may enter into a foreign currency contract to attempt to
    minimize the risk to the

                                AIM CHARTER FUND

                                       10
<PAGE>   13
    Fund from adverse changes in the relationship between currencies. The Fund
    may also enter into a foreign currency contract for the purchase or sale of
    a security denominated in a foreign currency in order to "lock in" the U.S.
    dollar price of that security. The Fund could be exposed to risk if
    counterparties to the contracts are unable to meet the terms of their
    contracts or if the value of the foreign currency changes unfavorably.
G.  Covered Call Options--The Fund may write call options, on a covered basis;
    that is, the Fund will own the underlying security. Options written by the
    Fund normally will have expiration dates between three and nine months from
    the date written. The exercise price of a call option may be below, equal
    to, or above the current market value of the underlying security at the time
    the option is written. When the Fund writes a covered call option, an amount
    equal to the premium received by the Fund is recorded 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
    written. The current market value of a written option is the mean between
    the last bid and asked prices on that day. If a written call option expires
    on the stipulated expiration date, or if the Fund enters into a closing
    purchase transaction, the Fund realizes a gain (or a loss if the closing
    purchase transaction exceeds the premium received when the option was
    written) without regard to any unrealized gain or loss on the underlying
    security, and the liability related to such option is extinguished. If a
    written option is exercised, the Fund realizes a gain or a loss from the
    sale of the underlying security and the proceeds of the sale are increased
    by the premium originally received.
         A call option gives the purchaser of such option the right to buy, and
    the writer (the Fund) the obligation to sell, the underlying security at the
    stated exercise price during the option period. The purchaser of a call
    option has the right to acquire the security which is the subject of the
    call option at any time during the option period. During the option period,
    in return for the premium paid by the purchaser of the option, the Fund has
    given up the opportunity for capital appreciation above the exercise price
    should the market price of the underlying security increase, but has
    retained the risk of loss should the price of the underlying security
    decline. During the option period, the Fund may be required at any time to
    deliver the underlying security against payment of the exercise price. This
    obligation is terminated upon the expiration of the option period or at such
    earlier time at which the Fund effects a closing purchase transaction by
    purchasing (at a price which may be higher than that received when the call
    option was written) a call option identical to the one originally written.
H.  Bond Premiums--It is the policy of the Fund not to amortize market premiums
    on bonds for financial reporting purposes.
I.  Expenses--Distribution expenses and certain transfer agency expenses
    directly attributable to a class of shares are charged to those classes'
    operations. All other expenses which are attributable to more than one class
    are allocated among the classes.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The Company has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment agreement, the
Fund pays an advisory fee to AIM at the annual rate of 1.0% of the first $30
million of the Fund's average daily net assets, plus 0.75% of the Fund's average
daily net assets in excess of $30 million to and including $150 million, plus
0.625% of the Fund's average daily net assets in excess of $150 million. AIM has
agreed to waive advisory fees paid by the Fund to AIM at the annual rate of
0.025% of the Fund's average daily net assets in excess of $2 billion. During
the six months ended April 30, 2000, AIM waived fees of $811,784. Under the
terms of a master sub-advisory agreement between AIM and A I M Capital
Management, Inc. ("AIM Capital"), AIM pays AIM Capital 50% of the amount paid by
the Fund to AIM.
    The Fund, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. For the six months ended April 30, 2000, AIM
was paid $183,509 for such services.
    The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agency and
shareholder services to the Fund. For the six months ended April 30, 2000, AFS
was paid $2,643,163 for such services.
    The Company has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares and a master distribution agreement with
Fund Management Company ("FMC") to serve as the distributor for the
Institutional Class shares of the Fund. The Company has adopted plans pursuant
to Rule 12b-1 under the 1940 Act with respect to the Fund's Class A shares,
Class B shares and Class C shares (collectively the "Plans"). The Fund, pursuant
to the Plans, pays AIM Distributors compensation at the annual rate of 0.30% of
the Fund's average daily net assets of Class A shares and 1.00% of the average
daily net assets of Class B and C shares. Of these amounts, the Fund may pay a
service fee of 0.25% of the average daily net assets of the Class A, Class B or
Class C 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 Plans also
impose a cap on the total sales charges, including asset-based sales charges
that may be paid by the respective classes. During the six months ended April
30, 2000, the Class A, Class B and Class C shares paid AIM Distributors
$8,365,548, $13,052,206 and $1,047,229, respectively, as compensation under the
Plans.
    AIM Distributors received commissions of $1,715,641 from sales of the Class
A shares of the Fund during the six months ended April 30, 2000. Such
commissions are not an expense of the Fund. They are deducted from, and are not
included in, the proceeds from sales of Class A shares. During the six months
ended April 30, 2000, AIM Distributors received $72,752 in contingent deferred
sales charges imposed on redemptions of Fund shares.

<PAGE>   14
    Certain officers and directors of the Company are officers and directors of
AIM, AFS, FMC and AIM Distributors.
    During the six months ended April 30, 2000, the Fund paid legal fees of
$5,867 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel
to the Company's directors. A member of that firm is a director of the Company.

NOTE 3-INDIRECT EXPENSES

transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $50,878 and $11,251, respectively, under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $62,129 during the six months ended April 30, 2000.

NOTE 4-DIRECTORS' FEES

Directors' fees represent remuneration paid to directors who are not an

by a director, in mutual fund shares in accordance with a deferred compensation
plan.

syndicate administered by The Chase Manhattan Bank. The Fund may borrow up to
the lesser of (i) $1,000,000,000 or (ii) the limits set by its prospectus for
borrowings. The Fund and other funds advised by AIM which are parties to the
line of credit may borrow on a first come, first served basis. During the six
months ended April 30, 2000, the Fund did not borrow under the line of credit
agreement. The funds which are party to the line of credit are charged a
commitment fee of 0.09% on the unused balance of the committed line. The
commitment fee is allocated among the funds based on their respective average
net assets for the period.

AIM CONSTELLATION FUND

AIM Constellation Fund is for shareholders who seek growth of capital by
investing principally in common stocks of companies the portfolio managers
believe are likely to benefit from new or innovative products, services or
processes as well as those that have experienced above-average long-term growth
in earnings and have excellent prospects for future growth.

ABOUT FUND PERFORMANCE AND PORTFOLIO DATA THROUGHOUT THIS REPORT:

o   AIM Constellation Fund's performance figures are historical, and they
    reflect the reinvestment of distributions and changes in net asset value.
o   The fund's investment return and principal value will fluctuate, so an
    investor's shares, when redeemed, may be worth more or less than their
    original cost.
o   Investing in small and mid-sized companies may involve greater risk and
    potential reward than investing in more established companies.

ABOUT INDEXES AND OTHER PERFORMANCE BENCHMARKS CITED IN THIS REPORT:

o   The Dow Jones Industrial Average (the Dow) is a price-weighted average of 30
    actively traded primarily industrial stocks.
o   The unmanaged Lipper Multi-Cap Growth Fund Index represents an average of
    the performance of the 30 largest multi-cap growth funds tracked by Lipper,

    considered representative of the small and medium-sized company stock
    universe. While it includes many small and mid-sized company stocks,
    large-capitalization technology companies tend to dominate the index.
o   The unmanaged Russell 2000 Index represents the performance of stocks of
    small-capitalization companies.

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW


FUND WEATHERS MARKET SELL-OFF, RECORDS EXCELLENT RETURNS


AFTER SOARING TO NEW HEIGHTS, STOCK INDEXES PLUNGED AS THE REPORTING PERIOD
CLOSED. HOW DID AIM CONSTELLATION FUND PERFORM?
Despite a steep drop in several key market indexes in April, the fund posted an
impressive return for the six-month period ended April 30, 2000. Total return
for the Institutional Class was 34.00%. The fund outperformed both the S&P 500
and the Lipper Multi-Cap Growth Fund Index, which recorded gains of 7.18% and
30.26%, respectively, over the same period.
    While technology stocks were volatile, the fund's heavy weighting in this
sector enhanced performance. Over the reporting period, the fund's total net
assets grew from $15.3 million to $20.7 million.

WHAT WERE THE KEY TRENDS IN THE STOCK MARKET?
For most of the reporting period, technology stocks were the undisputed market
leaders. Tech stocks helped push the Dow, the Nasdaq and other market indexes
to new heights. While the Dow peaked in January, the tech-dominated Nasdaq
continued to set records well into March. Toward the end of the month, however,
investors became concerned that tech stocks might be overvalued, sparking a
sharp sell-off in this sector. In April, a federal court ruling against
software giant Microsoft (not a fund holding) helped perpetuate this sell-off.
The stocks of Internet companies with no earnings were particularly hard hit.
    Investors were also concerned that the Federal Reserve Board (the Fed) might
continue to raise interest rates to slow torrid economic growth and contain
inflation. During the reporting period, the Fed, which launched a monetary
tightening policy in June 1999, raised the key federal funds rate--the rate
banks charge each other for overnight loans--from 5.25% to 6.0%. Interest-rate
concerns prompted a sell-off that affected nearly every stock-market sector in
April, causing markets to be extremely volatile.
    Despite April's well-publicized market downturn, most major indexes posted
gains for the reporting period, with mid-cap stocks leading the charge. The S&P
MidCap 400 Index was up 21.26% compared to 0.79% for the Dow and 18.72% for the
Russell 2000, which measures the performance of small-cap stocks. Despite
weakness in March and April, tech stocks still outperformed other issues for
the six-month reporting period by a significant margin.

HOW DID YOU MANAGE THE FUND?
During the reporting period, the fund implemented a new investment strategy
that permits it to invest in all sizes of companies instead of being limited to
mid- and small-cap stocks, allowing the fund to take advantage of rallies
within various market segments. We took advantage of April's market sell-off to
buy the stocks of quality companies at reduced prices.
    Over the last six months, we increased the fund's technology holdings from
46% to 51% while reducing consumer-cyclical stocks from 20% to 13% of the
portfolio. The portfolio's heavy weighting in the technology sector was a
result of our stock-selection criteria, which is based on earnings growth
prospects, not macroeconomic predictions. We continued to find many companies
with excellent earnings prospects in the technology sector. Moreover, we
generally do not buy the stocks of companies that have no earnings.
    Industries within the technology sector that were prominently represented in
the portfolio included computer software and services, communications equipment
and semiconductors. These industries are benefiting from the steady sales of
personal computers, the proliferation of new communications devices and the
expansion of the Internet.

CAN YOU NAME A FEW OF THE TECH STOCKS IN THE PORTFOLIO?
At the end of the reporting period, VERITAS Software was the portfolio's top
equity holding. VERITAS is the world's largest maker of storage-management
software, which protects networks against data loss from crashes and errors,
expedites data recovery and manages corporate storage. JDS Uniphase, the
portfolio's second-largest equity holding, is the world's leading supplier of
parts for fiber-optic equipment. Corning, our third-largest holding, is the
inventor and one of the world's top manufacturers of fiber-optic cable. All
three reported strong earnings for the most recent quarter.
   Other tech stocks in the portfolio included

    o   Analog Devices, a leading maker of both analog and digital integrated
        circuits, which translate such phenomena as pressure, temperature and
        sound into digital signals
    o   ADC Telecommunications, which makes systems that speed up the rate at
        which voice, data and video signals are transmitted
    o   PMC-Sierra, which develops semiconductor components that improve
        Internet transmission.

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW


    We believe the outlook is favorable for tech companies, which stand to
benefit from global economic expansion, mergers and acquisitions and the growth
of wireless communications and the Internet.

WHAT OTHER STOCKS PERFORMED WELL FOR THE FUND?
In the financial sector, the fund benefited from owning the stock of discount
brokerage firm Charles Schwab, a leading discount broker. In the energy sector,
a stock that performed well for the fund was Cooper Cameron, a maker of
equipment for the oil and gas industry.

WHAT IS YOUR OUTLOOK FOR THE NEAR TERM?
The near-term outlook for stocks could depend largely on the Fed's ability to
bring the economy to a "soft landing." On May 16, after the reporting period
ended, the central bank raised the federal funds rate to 6.5%. It appears that
the Fed's tightening cycle may be winding down, although the central bank may
approve additional rate increases in the immediate months ahead. If the Fed
succeeds in slowing economic growth to a more sustainable rate and keeping
inflation under control, it could prolong the current record economic
expansion. Such an environment could help sustain corporate earnings growth and
prove favorable for stocks.
    However, uncertainty over the Fed's actions and other factors could
perpetuate the volatility that has characterized markets in recent months. In
such an environment, investors would be well advised to take a long-term
perspective on their investment.

NOTES TO FINANCIAL STATEMENTS

April 30, 2000
(Unaudited)

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Constellation Fund (the "Fund") is a series portfolio of AIM Equity Funds,
Inc. (the "Company"). The Company is a Maryland corporation registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of eleven separate portfolios.
The Fund currently offers four different classes of shares: Class A shares,
Class B shares, Class C shares and the Institutional Class. Class A shares are
sold with a front-end sales charge. Class B shares and Class C shares are sold
with a contingent deferred sales charge. Matters affecting each portfolio or
class will be voted on exclusively by the shareholders of such portfolio or
class. The assets, liabilities and operations of each portfolio are accounted
for separately. Information presented in these financial statements pertains
only to the Fund. The Fund's investment objective is growth of capital.
    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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.
A.  Security Valuations -- A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price as of the close of the
    customary trading session on the exchange where the security is principally
    traded, or lacking any sales on a particular day, the security is valued at
    the closing bid price on that day. Each security reported on the NASDAQ
    National Market System is valued at the last sales price on the valuation
    date or absent a last sales price, at the closing bid price. Debt
    obligations (including convertible bonds) are valued on the basis of prices
    provided by an independent pricing service. Prices provided by the pricing
    service may be determined without exclusive reliance on quoted prices, and
    may reflect appropriate factors such as yield, type of issue, coupon rate
    and maturity date. Securities for which market prices are not provided by
    any of the above methods are valued based upon quotes furnished by
    independent sources and are valued at the last bid price in the case of
    equity securities and in the case of debt obligations, the mean between the
    last bid and asked prices. Securities for which market quotations are not
    readily available or are questionable are valued at fair value as determined
    in good faith by or under the supervision of the Company's officers in a
    manner specifically authorized by the Board of Directors of the Company.
    Short-term obligations having 60 days or less to maturity are valued at
    amortized cost which approximates market value. For purposes of determining
    net asset value per share, futures and option contracts generally will be
    valued 15 minutes after the close of the customary trading session of the
    New York Stock Exchange ("NYSE").
    Generally, trading in foreign securities is substantially completed each day
    at various times prior to the close of the NYSE. The values of such
    securities used in computing the net asset value of the Fund's shares are
    determined as of such times. Foreign currency exchange rates are also
    generally determined prior to the close of the NYSE. Occasionally, events
    affecting the values of such securities and such exchange rates may occur
    between the times at which they are determined and the close of the
    customary trading session of the NYSE which would not be reflected in the
    computation of the Fund's net asset value. If events materially affecting
    the value of such securities occur during such period, then these securities
    will be valued at their fair value as determined in good faith by or under
    the supervision of the Board of Directors.
B.  Securities Transactions and Investment Income -- Securities transactions are
    accounted for on a trade date basis. Realized gains or losses on sales are
    computed on the basis of specific identification of the securities sold.
    Interest income is recorded as earned from settlement date and is recorded
    on the accrual basis. Dividend income is recorded on the ex-dividend date.
C.  Distributions -- Distributions from income and net realized capital gains,
    if any, are generally paid annually and recorded on ex-dividend date. The
    Fund may elect to use a portion of the proceeds from redemptions as
    distributions for federal income tax purposes.
D.  Federal Income Taxes -- The Fund intends to comply with the requirements of
    the Internal Revenue Code necessary to qualify as a regulated investment
    company and, as such, will not be subject to federal income taxes on
    otherwise taxable income (including net realized capital gains) which is
    distributed to shareholders. Therefore, no provision for federal income
    taxes is recorded in the financial statements.
E.  Covered Call Options -- The Fund may write call options, on a covered basis;
    that is, the Fund will own the underlying security. Options written by the
    Fund normally will have expiration dates between three and nine months from
    the date written. The exercise price of a call option may be below, equal
    to, or above the current market value of the underlying security at the time
    the option is written. When the Fund writes a covered call option, an amount
    equal to the premium received by the Fund is recorded 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
    written. The current market value of a written option is the mean between
    the last bid and asked prices on that day. If a written call option expires
    on the stipulated expiration date, or if the Fund enters into a closing
    purchase transaction, the Fund realizes a gain (or a loss if the closing
    purchase transaction exceeds the premium

                             AIM CONSTELLATION FUND

                                       24
<PAGE>   27
    received when the option was written) without regard to any unrealized gain
    or loss on the underlying security, and the liability related to such option
    is extinguished. If a written option is exercised, the Fund realizes a gain
    or a loss from the sale of the underlying security and the proceeds of the
    sale are increased by the premium originally received.
         A call option gives the purchaser of such option the right to buy, and
    the writer (the Fund) the obligation to sell, the underlying security at the
    stated exercise price during the option period. The purchaser of a call
    option has the right to acquire the security which is the subject of the
    call option at any time during the option period. During the option period,
    in return for the premium paid by the purchaser of the option, the Fund has
    given up the opportunity for capital appreciation above the exercise price
    should the market price of the underlying security increase, but has
    retained the risk of loss should the price of the underlying security
    decline. During the option period, the Fund may be required at any time to
    deliver the underlying security against payment of the exercise price. This
    obligation is terminated upon the expiration of the option period or at such
    earlier time at which the Fund effects a closing purchase transaction by
    purchasing (at a price which may be higher than that received when the call
    option was written) a call option identical to the one originally written.
F.  Futures Contracts -- The Fund may purchase or sell futures contracts as a
    hedge against changes in market conditions. Initial margin deposits required
    upon entering into futures contracts are satisfied by the segregation of
    specific securities as collateral for the account of the broker (the Fund's
    agent in acquiring the futures position). During the period the futures
    contracts are open, changes in the value of the contracts are recognized as
    unrealized gains or losses by "marking to market" on a daily basis to
    reflect the market value of the contracts at the end of each day's trading.
    Variation margin payments are made or received depending upon whether
    unrealized gains or losses are incurred. When the contracts are closed, the
    Fund recognizes a realized gain or loss equal to the difference between the
    proceeds from, or cost of, the closing transaction and the Fund's basis in
    the contract. Risks include the possibility of an illiquid market and that a
    change in value of the contracts may not correlate with changes in the value
    of the securities being hedged.
G.  Expenses -- Distribution expenses and certain transfer agency expenses
    directly attributable to a class of shares are charged to those classes'
    operations. All other expenses which are attributable to more than one class
    are allocated among the classes.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The Company has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment agreement, the
Fund pays an advisory fee to AIM at the annual rate of 1.0% of the first $30
million of the Fund's average daily net assets, plus 0.75% of the Fund's average
daily net assets in excess of $30 million to and including $150 million, plus
0.625% of the Fund's average daily net assets in excess of $150 million. AIM has
agreed to waive advisory fees paid by the Fund to AIM at the annual rate of
0.025% of the Fund's average daily net assets in excess of $2 billion. During
the six months ended April 30, 2000, AIM waived fees of $2,181,249. Under the
terms of a master sub-advisory agreement between AIM and A I M Capital
Management, Inc. ("AIM Capital"), AIM pays AIM Capital 50% of the amount paid by
the Fund to AIM.
    The Fund, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. For the six months ended April 30, 2000, AIM
was paid $346,584 for such services.
    The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agency and
shareholder services to the Fund. For the six months ended April 30, 2000, AFS
was paid $5,609,953 for such services.
    The Company has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares and a master distribution agreement with
Fund Management Company ("FMC") to serve as the distributor for the
Institutional Class shares of the Fund. The Company has adopted plans pursuant
to Rule 12b-1 under the 1940 Act with respect to the Fund's Class A shares,
Class B shares and Class C shares (collectively the "Plans"). The Fund, pursuant
to the Plans, pays AIM Distributors compensation at the annual rate of 0.30% of
the Fund's average daily net assets of Class A shares and 1.00% of the average
daily net assets of Class B and C shares. Of these amounts, the Fund may pay a
service fee of 0.25% of the average daily net assets of the Class A, Class B or
Class C 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 Plans also
impose a cap on the total sales charges, including asset-based sales charges
that may be paid by the respective classes. During the six months ended April
30, 2000, the Class A, Class B and Class C shares paid AIM Distributors
$26,982,803, $4,237,526 and $1,252,867, respectively, as compensation under the
Plans.
    AIM Distributors received commissions of $2,511,724 from sales of the Class
A shares of the Fund during the six months ended April 30, 2000. Such
commissions are not an expense of the Fund. They are deducted from, and are not
included in, the proceeds from sales of Class A shares. During the six months
ended April 30, 2000, AIM Distributors received $168,593 in contingent deferred
sales charges imposed on redemptions of Fund shares.

                                       25
<PAGE>   28

    Certain officers and directors of the Company are officers and directors of
AIM, AFS, FMC and AIM Distributors.
    During the six months ended April 30, 2000, the Fund paid legal fees of
$11,277 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as
counsel to the Company's directors. A member of that firm is a director of the
Company.

NOTE 3-INDIRECT EXPENSES

During the six months ended April 30, 2000, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $116,741 and $45,089, respectively, under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $161,830 during the six months ended April 30, 2000.

NOTE 4-DIRECTORS' FEES

Directors' fees represent remuneration paid to directors who are not an
"interested person" of AIM. The Company invests directors' fees, if so elected
by a director, in mutual fund shares in accordance with a deferred compensation
plan.

NOTE 5-BANK BORROWINGS

The Fund is a participant in a committed line of credit facility with a
syndicate administered by The Chase Manhattan Bank. The Fund may borrow up to
the lesser of (i) $1,000,000,000 or (ii) the limits set by its prospectus for
borrowings. The Fund and other funds advised by AIM which are parties to the
line of credit may borrow on a first come, first served basis. During the six
months ended April 30, 2000, the Fund did not borrow under the line of credit
agreement. The funds which are party to the line of credit are charged a
commitment fee of 0.09% on the unused balance of the committed line. The
commitment fee is allocated among the funds based on their respective average
net assets for the period.

NOTE 6-INVESTMENT SECURITIES

The aggregate amount of investment securities (other than short-term securities)

AIM Weingarten Fund is for shareholders who seek long-term growth of capital
through investments primarily in common stocks of leading U.S. companies
considered by management to have strong earnings momentum.

ABOUT FUND PERFORMANCE AND PORTFOLIO DATA THROUGHOUT THIS REPORT:

o   AIM Weingarten Fund's performance figures are historical, and they reflect
    the reinvestment of distributions and changes in net asset value.
o   The fund's investment return and principal value will fluctuate, so an
    investor's shares, when redeemed, may be worth more or less than their
    original cost.

o   The unmanaged Lipper Growth Fund Index represents an average of the
    performance of the 30 largest growth funds charted by Lipper, Inc., an

    While it includes many small and mid-sized company stocks,
    large-capitalization technology stocks tend to dominate the index.
o   The unmanaged Russell 1000 Index represents the performance of the stocks of
    large-capitalization companies.

AIM WEINGARTEN FUND CONTINUES RECORD OF OUTSTANDING PERFORMANCE

HOW DID AIM WEINGARTEN FUND PERFORM OVER THE LAST SIX MONTHS?
For the six months ended April 30, 2000, AIM Weingarten Fund delivered
outstanding returns and outperformed both the Lipper Large-Cap Growth Index and
the Russell 1000 Index. Total return for the Institutional Class was 26.46%,
which handily beat the Lipper Large-Cap Growth Index's 16.31% and the Russell
1000 Index's 9.72% returns for the reporting period.
    The fund's assets continue to grow. Net assets rose from $114.1 million to
$147.1 million during the reporting period.

WHAT WERE THE MAJOR TRENDS IN THE FINANCIAL MARKETS DURING THE REPORTING
PERIOD?
U.S. equity markets experienced unprecedented volatility during the last six
months. Many technology stocks that soared in 1999 came crashing back to earth
in early 2000 as investors questioned those stocks' valuations. Many investors
abandoned dot-com stocks, concerned that they were overvalued, lacked a clear
business model and might never make a profit.
    But even the stocks of large, historically profitable old economy companies
were not immune to price declines if it appeared they might not meet earnings
expectations. Investors increasingly focused on corporate profits, and many
companies that failed to deliver profits to their shareholders were punished.
    There were many reasons for the markets' heightened volatility, including
continued interest-rate hikes by the Federal Reserve Board (the Fed) and
sometimes contradictory economic indicators. The Fed raised short-term interest
rates five times during the last year for a total increase of 125 basis points
(1.25%) in a preemptive effort to contain inflation. (On May 16, shortly after
the close of the reporting period, the Fed raised short-term interest rates by
an additional 50 basis points and signaled that it may raise rates further.)
    For all the headline-making one-day dips and dives in one market benchmark
or another, it is worth noting that the most widely followed market indexes all
produced positive returns for the six months covered by this report. The S&P 500
rose 7.18%; the Dow eked out a 0.79% gain; and even the Nasdaq, which provoked
the most hand-wringing, was up an impressive 30.14%.

HAS MARKET VOLATILITY AFFECTED ALL STOCKS EQUALLY?
Not all stocks have been equally volatile. Much of the volatility has been
concentrated among profitless Internet stocks with high price-to-earnings
multiples--precisely the kind of stocks in which the fund does not invest. The
stocks of larger, more established companies have been comparatively stable.
While the technology-laden Nasdaq was down 5.13% for the first four months of
2000, the S&P 500 Index was down only 0.79%.

HOW WAS THE FUND'S PORTFOLIO POSITIONED AT THE CLOSE OF THE REPORTING PERIOD?
The fund held a widely diversified portfolio of 85 stocks in a variety of
sectors and industries at the close of the reporting period. Major sectors
represented in the portfolio on April 30, 2000, were technology (58.9%),
consumer staples (11.9%), consumer cyclicals (8.1%), health care (8.0%) and
capital goods (6.0%). Within the technology sector, the fund held stocks in a
variety of well-established companies in the communications equipment,
semiconductor, computer software and services and semiconductor equipment
industries.
    Technology stocks accounted for approximately 42% of the fund's hold-
ings at the beginning of the period and approximately 59% at its close. We
reduced our health-care holdings from about 15% to 8% of the fund's portfolio
because many health-care companies face potential problems. Some pharmaceutical
manufacturers face patent expirations; some managed-care companies have seen
rising costs and reduced government reimbursements squeeze their earnings; and
some biotech companies have been hurt by adverse decisions from the U.S. Food
and Drug Administration.
    We slightly reduced our domestic holdings from 95% to 88% of the portfolio
during the period, and we increased our foreign holdings from about 5% to 12%.
The capitalization levels of our holdings remained essentially unchanged, with
roughly 90% of our holdings in the large- or super-cap range.

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW



WHAT WERE SOME OF THE FUND'S MAJOR HOLDINGS?
A large percentage of the fund's holdings were in the technology
sector--mainly well-established, profitable companies that are leaders in
their fields. One of the fund's largest technology holdings, Sun Microsystems,
reported extremely strong quarterly earnings shortly before the close of the
reporting period. Sun is a leading maker of number-crunching workstation
computers, storage devices and servers for powering corporate computer systems
and Web sites.
    Many of the fund's non-tech holdings also performed well. Home Depot, a
stock we continued to like, is noted for its outstanding customer service. It
operates more than 950 stores coast to coast serving both professional builders
and "do-it-yourselfers." The company is opening a new chain of smaller hardware
stores in the United States and is exporting its superstore concept to South
America. In the health-care sector, Warner-Lambert--the fund's largest single
holding--makes some of the best-known consumer products on the market. But 60%
of its sales come from its pharmaceutical products, including Lipitor, a
market-leading cholesterol treatment.

WHAT IS YOUR OUTLOOK FOR THE FUTURE?
U.S. and foreign markets may remain volatile for some time because of rising
interest rates and because some investors have yet to figure out the proper way
to value high-growth technology companies. While the Fed traditionally refrains
from raising interest rates during presidential elections, it has made clear
its intention to continue raising rates as necessary to ensure that inflation
remains in check.
    Technology and telecommunications companies in the United States and
elsewhere are producing innovative new products and infrastructure that could
result in many years of above-average growth. While further Fed rate hikes could
put pressure on more traditional sectors of the economy, many industry-leading
technology companies have little debt, making them somewhat immune to the
effects of rising interest rates. AIM Weingarten Fund intends to own
well-managed, financially strong, industry-leading companies with the potential
to appreciate in the years ahead.

NOTES TO FINANCIAL STATEMENTS

April 30, 2000
(Unaudited)

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Weingarten Fund (the "Fund") is a series portfolio of AIM Equity Funds, Inc.
(the "Company"). The Company is a Maryland corporation registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of eleven separate portfolios.
The Fund currently offers four different classes of shares: Class A shares,
Class B shares, Class C shares and the Institutional Class. Class A shares are
sold with a front-end sales charge. Class B shares and Class C shares are sold
with a contingent deferred sales charge. Matters affecting each portfolio or
class will be voted on exclusively by the shareholders of such portfolio or
class. The assets, liabilities and operations of each portfolio are accounted
for separately. Information presented in these financial statements pertains
only to the Fund. The Fund's investment objective is growth of capital primarily
by investing in common stocks of seasoned and better-capitalized companies.
    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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.

A.  Security Valuations--A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price as of the close of the
    customary trading session on the exchange where the security is principally
    traded, or lacking any sales on a particular day, the security is valued at
    the closing bid price on that day. Each security reported on the NASDAQ
    National Market System is valued at the last sales price on the valuation
    date or absent a last sales price, at the closing bid price. Debt
    obligations (including convertible bonds) are valued on the basis of prices
    provided by an independent pricing service. Prices provided by the pricing
    service may be determined without exclusive reliance on quoted prices, and
    may reflect appropriate factors such as yield, type of issue, coupon rate
    and maturity date. Securities for which market prices are not provided by
    any of the above methods are valued based upon quotes furnished by
    independent sources and are valued at the last bid price in the case of
    equity securities and in the case of debt obligations, the mean between the
    last bid and asked prices. Securities for which market quotations are not
    readily available or are questionable are valued at fair value as determined
    in good faith by or under the supervision of the Company's officers in a
    manner specifically authorized by the Board of Directors of the Company.
    Short-term obligations having 60 days or less to maturity are valued at
    amortized cost which approximates market value. For purposes of determining
    net asset value per share, futures and option contracts generally will be
    valued 15 minutes after the close of the customary trading session of the
    New York Stock Exchange ("NYSE").
         Generally, trading in foreign securities is substantially completed
    each day at various times prior to the close of the NYSE. The values of such
    securities used in computing the net asset value of the Fund's shares are
    determined as of such times. Foreign currency exchange rates are also
    generally determined prior to the close of the NYSE. Occasionally, events
    affecting the values of such securities and such exchange rates may occur
    between the times at which they are determined and the close of the
    customary trading session of the NYSE which would not be reflected in the
    computation of the Fund's net asset value. If events materially affecting
    the value of such securities occur during such period, then these securities
    will be valued at their fair value as determined in good faith by or under
    the supervision of the Board of Directors.
B.  Securities Transactions and Investment Income--Securities transactions are
    accounted for on a trade date basis. Realized gains or losses on sales are
    computed on the basis of specific identification of the securities sold.
    Interest income is recorded as earned from settlement date and is recorded
    on the accrual basis. Dividend income is recorded on the ex-dividend date.
C.  Distributions--Distributions from income and net realized capital gains, if
    any, are generally paid annually and recorded on ex-dividend date. The Fund
    may elect to use a portion of the proceeds from redemptions as distributions
    for federal income tax purposes.
D.  Federal Income Taxes--The Fund intends to comply with the requirements of
    the Internal Revenue Code necessary to qualify as a regulated investment
    company and, as such, will not be subject to federal income taxes on
    otherwise taxable income (including net realized capital gains) which is
    distributed to shareholders. Therefore, no provision for federal income
    taxes is recorded in the financial statements.
E.  Foreign Currency Translations--Portfolio securities and other assets and
    liabilities denominated in foreign currencies are translated into U.S.
    dollar amounts at date of valuation. Purchases and sales of portfolio
    securities and income items denominated in foreign currencies are translated
    into U.S. dollar amounts on the respective dates of such transactions. The
    Fund does not separately account for that portion of the results of
    operations resulting from changes in foreign exchange rates on investments
    and the fluctuations arising from changes in market prices of securities
    held. Such fluctuations are included with the net realized and unrealized
    gain or loss from investments.

<PAGE>   40

F.  Foreign Currency Contracts--A foreign currency contract is an obligation to
    purchase or sell a specific currency for an agreed-upon price at a future
    date. The Fund may enter into a foreign currency contract to attempt to
    minimize the risk to the Fund from adverse changes in the relationship
    between currencies. The Fund may also enter into a foreign currency contract
    for the purchase or sale of a security denominated in a foreign currency in
    order to "lock in" the U.S. dollar price of that security. The Fund could be
    exposed to risk if counterparties to the contracts are unable to meet the
    terms of their contracts or if the value of the foreign currency changes
    unfavorably.
G.  Covered Call Options--The Fund may write call options, on a covered basis;
    that is, the Fund will own the underlying security. Options written by the
    Fund normally will have expiration dates between three and nine months from
    the date written. The exercise price of a call option may be below, equal
    to, or above the current market value of the underlying security at the time
    the option is written. When the Fund writes a covered call option, an amount
    equal to the premium received by the Fund is recorded 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
    written. The current market value of a written option is the mean between
    the last bid and asked prices on that day. If a written call option expires
    on the stipulated expiration date, or if the Fund enters into a closing
    purchase transaction, the Fund realizes a gain (or a loss if the closing
    purchase transaction exceeds the premium received when the option was
    written) without regard to any unrealized gain or loss on the underlying
    security, and the liability related to such option is extinguished. If a
    written option is exercised, the Fund realizes a gain or a loss from the
    sale of the underlying security and the proceeds of the sale are increased
    by the premium originally received.
         A call option gives the purchaser of such option the right to buy, and
    the writer (the Fund) the obligation to sell, the underlying security at the
    stated exercise price during the option period. The purchaser of a call
    option has the right to acquire the security which is the subject of the
    call option at any time during the option period. During the option period,
    in return for the premium paid by the purchaser of the option, the Fund has
    given up the opportunity for capital appreciation above the exercise price
    should the market price of the underlying security increase, but has
    retained the risk of loss should the price of the underlying security
    decline. During the option period, the Fund may be required at any time to
    deliver the underlying security against payment of the exercise price. This
    obligation is terminated upon the expiration of the option period or at such
    earlier time at which the Fund effects a closing purchase transaction by
    purchasing (at a price which may be higher than that received when the call
    option was written) a call option identical to the one originally written.
H.  Put Options--The Fund may purchase put options. By purchasing a put option,
    the Fund obtains the right (but not the obligation) to sell the option's
    underlying instrument at a fixed strike price. In return for this right, the
    Fund pays an option premium. The option's underlying instrument may be a
    security or a futures contract. Put options may be used by the Fund to hedge
    securities it owns by locking in a minimum price at which the Fund can sell.
    If security prices fall, the put option could be exercised to offset all or
    a portion of the Fund's resulting losses. At the same time, because the
    maximum the Fund has at risk is the cost of the option, purchasing put
    options does not eliminate the potential for the Fund to profit from an
    increase in the value of the securities hedged.
I.  Futures Contracts--The Fund may purchase or sell futures contracts as a
    hedge against changes in market conditions. Initial margin deposits required
    upon entering into futures contracts are satisfied by the segregation of
    specific securities as collateral for the account of the broker (the Fund's
    agent in acquiring the futures position). During the period the futures
    contracts are open, changes in the value of the contracts are recognized as
    unrealized gains or losses by "marking to market" on a daily basis to
    reflect the market value of the contracts at the end of each day's trading.
    Variation margin payments are made or received depending upon whether
    unrealized gains or losses are incurred. When the contracts are closed, the
    Fund recognizes a realized gain or loss equal to the difference between the
    proceeds from, or cost of, the closing transaction and the Fund's basis in
    the contract. Risks include the possibility of an illiquid market and that a
    change in value of the contracts may not correlate with changes in the value
    of the securities being hedged.
J.  Expenses--Distribution expenses and certain transfer agency expenses
    directly attributable to a class of shares are charged to those classes'
    operations. All other expenses which are attributable to more than one class
    are allocated among the classes.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The Company has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment advisory
agreement, the Fund pays an advisory fee to AIM at the annual rate of 1.0% of
the first $30 million of the Fund's average daily net assets, plus 0.75% of the
Fund's average daily net assets in excess of $30 million to and including $350
million, plus 0.625% of the Fund's average daily net assets in excess of $350
million. AIM has agreed to waive advisory fees payable by the Fund to AIM at the
annual rate of 0.025% of the Fund's average daily net assets in excess of $2
billion to and including $3 billion, 0.05% of the Fund's average daily net
assets in excess of $3 billion to and including $4 billion and 0.075% of the
Fund's average daily net assets in excess of $4 billion. During the six months
ended April 30, 2000, AIM waived fees of $3,227,861. Under the terms of a master
sub-advisory agreement between AIM and A I M Capital Management, Inc. ("AIM
Capital"), AIM pays AIM Capital 50% of the amount paid by the Fund to AIM.
    The Fund, pursuant to a master administrative services agreement with AIM,
has agreed to pay AIM for certain administrative costs incurred in providing
accounting services to the Fund. For the six months ended April 30, 2000, AIM
was paid $233,704 for such services.

    The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agency and
shareholder services to the Fund. For the six months ended April 30, 2000, AFS
was paid $3,271,266 for such services.
    The Company has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares and a master distribution agreement with
Fund Management Company ("FMC") to serve as the distributor for the
Institutional Class shares of the Fund. The Company has adopted plans pursuant
to Rule 12b-1 under the 1940 Act with respect to the Fund's Class A shares,
Class B shares and Class C shares (collectively the "Plans"). The Fund, pursuant
to the Plans, pays AIM Distributors compensation at the annual rate of 0.30% of
the Fund's average daily net assets of Class A shares and 1.00% of the average
daily net assets of Class B and C shares. Of these amounts, the Fund may pay a
service fee of 0.25% of the average daily net assets of the Class A, Class B or
Class C 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 Plans also
impose a cap on the total sales charges, including asset-based sales charges
that may be paid by the respective classes. During the six months ended April
30, 2000, the Class A, Class B and Class C shares paid AIM Distributors
$14,418,877, $8,300,610 and $863,405, respectively, as compensation under the
Plans.
    AIM Distributors received commissions of $1,950,209 from sales of the Class
A shares of the Fund during the six months ended April 30, 2000. Such
commissions are not an expense of the Fund. They are deducted from, and are not
included in, the proceeds from sales of Class A shares. During the six months
ended April 30, 2000, AIM Distributors received $50,445 in contingent deferred
sales charges imposed on redemptions of Fund shares.
    Certain officers and directors of the Company are officers and directors of
AIM, AFS, FMC and AIM Distributors.
    During the six months ended April 30, 2000, the Fund paid legal fees of
$7,364 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel
to the Company's directors. A member of that firm is a director of the Company.

NOTE 3-INDIRECT EXPENSES

During the six months ended April 30, 2000, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $69,518 and $34,828, respectively, under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $104,346 during the six months ended April 30, 2000.

NOTE 4-DIRECTORS' FEES

Directors' fees represent remuneration paid to directors who are not an
"interested person" of AIM. The Company invests directors' fees, if so elected
by a director, in mutual fund shares in accordance with a deferred compensation
plan.

NOTE 5-BANK BORROWINGS

The Fund is a participant in a committed line of credit facility with a
syndicate administered by The Chase Manhattan Bank. The Fund may borrow up to
the lesser of (i) $1,000,000,000 or (ii) the limits set by its prospectus for
borrowings. The Fund and other funds advised by AIM which are parties to the
line of credit may borrow on a first come, first served basis. During the six
months ended April 30, 2000, the Fund did not borrow under the line of credit
agreement. The funds which are party to the line of credit are charged a
commitment fee of 0.09% on the unused balance of the committed line. The
commitment fee is allocated among the funds based on their respective average
net assets for the period.

NOTE 6-INVESTMENT SECURITIES
