AIM Municipal Bond Fund is for shareholders who seek a high level of current
income exempt from federal income taxes by investing in a diversified portfolio
of municipal bonds.

ABOUT FUND PERFORMANCE AND PORTFOLIO DATA THROUGHOUT THIS REPORT:

o   AIM Municipal Bond Fund's performance figures are historical, and they
    reflect changes in net asset value and reinvestment of distributions.

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

o   The 30-day yield is calculated using a formula defined by the SEC. The
    formula is based on the portfolio's potential earnings from dividends,
    interest, yield-to-maturity, or yield-to-call of the portfolio's bond
    holdings, net of all expenses and annualized.

o   The taxable-equivalent yield is calculated in the same manner as the 30-day
    yield with an adjustment for a stated, assumed tax rate.

o   The fund's annualized distribution rate reflects its most recent monthly
    dividend distribution multiplied by 12 and divided by the most recent
    month-end net asset value.

o   Government securities, such as U.S. Treasury bills, notes and bonds, offer a
    high degree of safety and are guaranteed as to the timely payment of
    principal and interest if held to maturity. Fund shares are not insured, and
    their value will vary with market conditions.

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.

ABOUT INDEXES AND OTHER PERFORMANCE BENCHMARKS CITED IN THIS REPORT:

o   The unmanaged Lehman Municipal Bond Index is a composite representing an
    approximation of the performance of investment-grade municipal bonds,
    tracked by Lehman Brothers, a well-known global investment bank.

o   The unmanaged Lipper Municipal Debt Funds Index represents an average of the
    performance of the 30 largest municipal-bond funds tracked by Lipper, Inc.,
    an independent mutual fund performance monitor.

o   An investment cannot be made in an index. Unless otherwise indicated, index
    results include reinvested dividends and do not reflect sales charges.

   AN INVESTMENT IN THE FUND IS NOT A DEPOSIT OF A BANK AND IS NOT INSURED OR
      GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER
     GOVERNMENT AGENCY. THERE IS A RISK THAT YOU COULD LOSE SOME OR ALL OF
                                  YOUR MONEY.

   This report may be distributed only to current shareholders or to persons
              who have received a current prospectus of the fund.

                        ANNUAL REPORT / CHAIRMAN'S LETTER




                    Dear Fellow Shareholder:

                    The fiscal year discussed in this report has reconfirmed our
     [PHOTO OF      faith in two long-established principles of investing:
    Charles T.      portfolio diversification and long-term thinking. We could
      Bauer,        title this report "What a Difference a Year Makes."
    Chairman of         An investor surveying conditions when the fiscal year
   the Board of     opened on January 1, 1999, would have seen a market
     THE FUND       dominated by large-capitalization stocks and high-quality
   APPEARS HERE]    bonds, especially U.S. Treasuries. During 1998, two
                    well-known indexes of large-capitalization U.S. companies,
                    the S&P 500 and the Dow Jones Industrial Average, were up
                    28.60% and 18.15%, respectively. By contrast,
                    smaller-company stocks in the Russell 2000 had lost 2.55%.
                    Overseas, many markets were languishing, especially in Asia,
                    where so many financial difficulties had originated in 1997.
                        In bond markets as well, name-brand quality was the
                    place to be. The Lehman Government/Corporate Bond Index,
which follows sovereign issues and investment-grade debt, was up 9.47%, while
the Lehman High Yield Index, which tracks riskier "junk bonds," had risen only
1.60%.
    It would be easy for an investor to conclude that blue-chip issues, whether
equity or fixed-income, were the place to be, that it was time to divest himself
of everything else and put all his eggs in the blue-chip basket. The investor,
of course, would be wrong.

MARKETS TURN
While large-capitalization stocks continued to do very well, during 1999 markets
broadened dramatically with many investment sectors performing a complete
turnaround. For example, the small-cap stocks in the Russell 2000 were up 21.26%
for calendar year 1999, and many Asian markets, particularly Japan, had staged a
comeback.
    The same holds true of bonds. The higher-quality Lehman index was down 2.15%
during 1999 while the Lehman High Yield index was up 2.39%.
    The point, at the risk of sounding repetitive to those of you who have
invested with us for a long time, is that this is why diversification is a
fundamental investing principle. Market sectors and asset classes go in and out
of favor, but over the long run--and the long run is several years--the markets'
overall trend has been upward. Selecting an asset class or a market sector on
the basis of a short-term snapshot of conditions is usually unwise, as is
concentrating your portfolio in one asset class. Staying fully invested in a
diversified portfolio remains a compelling strategy and one of your best
prospects for long-term gain. We also continue to remind you that the past few
years have seen extraordinary gains in some markets, and there is no assurance
that this trend will continue.

LOOKING AHEAD
As we look about at the close of this fiscal year, we are encouraged by multiple
signs of economic health in Europe and Asia, not to mention the prolonged U.S.
economic expansion. However, we are aware of how easily an investor could have
been misled by conditions just 12 months ago. For our shareholders, we therefore
reiterate our commitment to investing through a financial advisor. In addition
to helping you select investments appropriate to your time horizon and risk
tolerance, a financial advisor can keep you informed about how changing market
conditions affect you and your portfolio--and help ensure that when you do alter
your investments, there's a logical reason for doing so. AIM believes every
investor should be guided by a financial professional.

FUND MANAGERS COMMENT

managed your fund during the year ended December 31, how the markets behaved and
what they foresee for the near future. We trust you will find their discussion
informative. If you have any questions or comments, we invite you to contact us,

                       ANNUAL REPORT / MANAGERS' OVERVIEW


FUND OFFERS ATTRACTIVE YIELD DESPITE
DISMAL BOND MARKET

RISING INTEREST RATES HAD A NEGATIVE IMPACT ON BONDS, INCLUDING MUNICIPAL
ISSUES. HOW DID THE FUND PERFORM?
Although the bond market endured its worst year since 1994, the fund provided
attractive current income (see chart below), exempt from federal income taxes,
while maintaining relative share-price stability. During the fiscal year, net
asset value per share remained within a relatively narrow range of $7.74 to
$8.42 for Class A, Class B and Class C shares, extending the fund's long-time
record of relative price stability as shown on the accompanying chart.
    We manage the fund in an effort to protect it during market downturns like
the one experienced in 1999. In line with this strategy, we avoid buying
discounted bonds, which can be more volatile in price. We also strive to keep
the fund's weighted average maturity relatively short. For the year ended
December 31, 1999, total return was -2.45%, -3.28% and -3.16% for Class A, Class
B and Class C shares, respectively, excluding sales charges. The fund fared
better than its peer group, the Lipper Municipal Debt Funds Index, which
recorded a total return of -4.63%. Please keep in mind that the fund is managed
for income and stability of net asset value rather than total return.

WHAT WERE SOME OF THE MAJOR TRENDS IN THE BOND MARKET?
The weakness in the bond market in 1999 stemmed primarily from investor concerns
that strong economic growth would prompt the Federal Reserve Board (the Fed) to
raise interest rates to keep inflation at bay. Ultimately, in three separate
moves, the central bank raised the key federal funds rate from 4.75% to 5.50%.
The bond market was also rattled by Y2K concerns, which largely proved to be
unfounded, and the decline in value of the U.S. dollar against the Japanese yen.
    U.S. Treasury issues endured their worst 12-month performance in 22 years.
The weakness in the Treasury market was reflected in the yield of the benchmark
30-year Treasury bond, which rose from 5.09% at the beginning of the fiscal year
to 6.48% at its conclusion. At the end of the reporting period, Treasury yields
were at their highest levels in more than two years.
    Only a few bond sectors, such as high-yield corporate bonds and
emerging-markets debt, posted gains for the reporting period. Most other types
of bonds at least performed better than Treasuries. Lower-rated bonds outpaced
higher-rated bonds and shorter-term securities outperformed longer-term
securities.

HOW DID MUNICIPAL BONDS PERFORM?
Municipal bonds (munis) tended to track the performance of Treasuries. Muni bond
prices, relatively stable at the beginning of the year, began to decline in
April, sending their yields higher. Treasury yields also rose, but not as
significantly as muni yields.
    As a result, the gap between Treasury and muni yields narrowed. By the end
of the fiscal year, muni yields were more than

90% of those of Treasuries, above the historical average of roughly 85%. Munis
thus were attractively priced in comparison to Treasuries and represented one of
the better bargains in the bond market.
    Rising interest rates and weak demand deflated municipal bond prices. These
factors also contributed to a decline in new issue volume. In 1999, about $226
billion in new municipal bonds entered the market, nearly a 21% decline from
1998, according to The Bond Buyer, a newspaper that tracks the muni bond market.
State and local governments cut back on issuing new bonds and refinancing older
issues as the cost of borrowing money increased.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?
The fund had 281 holdings. Revenue bonds, which are supported with income from
various projects, made up 57% of the portfolio. The focus was on bonds for
essential-service projects, particularly hospitals, water-treatment facilities
and utilities.
     The fund had an average portfolio quality rating of AA/Aa as measured by
Standard & Poor's (S&P) and Moody's, two widely known credit-rating agencies.
S&P and Moody's historical ratings are based on an analysis of the credit
quality of the individual municipal securities in the fund's portfolio.
    Approximately 60% of the fund's holdings were securities rated AAA, and 88%
of the portfolio was rated A or better. Credit-enhanced securities--those backed
by insurance or escrowed with U.S. Treasury securities--composed about 58% of
the portfolio.

HOW TAX EFFICIENT WAS THE FUND?
For six years, the fund has paid no taxable capital-gains distributions . We
endeavor to avoid transactions that would result in capital gains that are not
offset by capital losses.

WHAT IS YOUR OUTLOOK?
The near-term outlook for bonds, including municipal issues, will likely depend
largely on the strength of the economy. If the economy continues to grow at a
blistering pace, it could have a negative impact on the bond market. On February
2, after the close of the reporting period, the Fed raised the federal funds
rate to 5.75%. We expect the Fed to raise interest rates again in the months
ahead to slow economic growth and forestall inflation. If economic growth
moderates as 2000 progresses, interest rates could level off, and that could
have a positive impact on the bond market. And while past performance cannot
guarantee comparable future results, the U.S. bond market has seldom had two
dismal years in a row.
    Factors that could work in favor of municipal bonds in the next few months
include their attractive valuations and yields in comparison to Treasuries and a
continuing decline in new issue volume. Regardless of market trends, we will
continue to manage the fund for attractive income, exempt from federal income
taxes, while maintaining relative stability of net asset value per share.

ABOUT THIS CHART
This chart compares the performance of your fund's Class A shares to a benchmark
index over the period 12/31/89- 12/31/99. It is important to understand the
differences between your fund and an index. Your fund's total return is shown
with a sales charge and includes fund expenses and management fees. An index
measures the performance of a hypothetical portfolio. A market index such as the
Lehman Municipal Bond Index is not managed, incurring no sales charges, expenses
or fees. If you could buy all the securities that make up a market index, you
would incur expenses that would affect your investment's return.

December 31, 1999

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Municipal Bond Fund (the "Fund") is a series portfolio of AIM Funds Group
(the "Trust"). The Trust is a Delaware business trust registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of nine separate portfolios,
each having an unlimited number of shares of beneficial interest. The Fund
currently offers three different classes of shares: Class A shares, Class B
shares and Class C shares. 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 to achieve a high level of current income
exempt from federal income taxes, consistent with the preservation of principal,
by investing in a diversified portfolio of municipal bonds.
  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 -- Portfolio securities are valued on the basis of prices
   provided by an independent pricing service approved by the Board of Trustees,
   provided that securities with a demand feature exercisable within one to
   seven days will be valued at par. Prices provided by the pricing service may
   be determined without exclusive reliance on quoted prices and may reflect
   appropriate factors such as institution-size trading in similar groups of
   securities, yield, quality, coupon rate, maturity, type of issue, individual
   trading characteristics and other market data. Portfolio securities for which
   prices are not provided by the pricing service are valued at the mean between
   the last available bid and asked prices, unless the Board of Trustees, or
   persons designated by the Board of Trustees, determines that the mean between
   the last available bid and asked prices does not accurately reflect the
   current market value of the security. Securities for which market quotations
   either are not readily available or are questionable are valued at fair value
   as determined in good faith by or under the supervision of the Trust's
   officers in a manner specifically authorized by the Board of Trustees.
   Notwithstanding the above, short-term obligations with maturities of 60 days
   or less are valued at amortized cost.
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. On
   December 31, 1999, undistributed net investment income was increased by
   $362,527 and paid-in capital decreased by $362,527 as a result of differing
   book/tax treatment reclassifications. Net assets of the Fund were unaffected
   by the reclassifications.
C. Distributions -- It is the policy of the Fund to declare daily dividends from
   net investment income. Such distributions are paid monthly. Distributions
   from 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 of fund share 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. The Fund has a capital loss
   carryforward of $2,805,103 as of December 31, 1999 which may be carried
   forward to offset future taxable gains, if any, which expires in varying
   increments, if not previously utilized, in the year 2007.
E. Expenses -- Distribution expenses and transfer agency expenses directly
   attributable to a class of shares are charged to that class' 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 Trust 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 an annual rate of 0.50% on
the first $200 million of the Fund's average daily net assets, plus 0.40% on the
next $300 million of the Fund's average daily net assets, plus 0.35% on the next
$500 million of the Fund's average daily net assets, plus 0.30% on the Fund's
average daily net assets in excess of $1 billion.
  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 year ended December 31, 1999, AIM was
paid $91,647 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.

                                       19
<PAGE>   22

For the year ended December 31, 1999, AFS was paid $138,338 for such services.
  The Trust 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 of the Fund. The Trust 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
0.25% 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. For the year ended December 31,
1999, the Class A, Class B and Class C shares paid AIM Distributors $805,244,
$753,522 and $101,726, respectively, as compensation under the Plans.
  AIM Distributors received commissions of $97,187 from sales of the Class A
shares of the Fund during the year ended December 31, 1999. 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 year ended December 31, 1999,
AIM Distributors received $123,118 in contingent deferred sales charges imposed
on redemptions of Fund shares.
  Certain officers and trustees of the Trust are officers and directors of AIM,
AFS and AIM Distributors.
  During the year ended December 31, 1999, the Fund paid legal fees of $4,178
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Board of Trustees. A member of that firm is a trustee of the Trust.

NOTE 3-INDIRECT EXPENSES

During the year ended December 31, 1999, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) of $4,633 under an expense
offset arrangement. The effect of the above arrangement resulted in a reduction
of the Fund's total expenses of $4,633 during the year ended December 31, 1999.

NOTE 4-TRUSTEES' FEES

Trustees' fees represent remuneration paid to trustees who are not an
"interested person" of AIM. The Trust invests trustees' fees, if so elected by a
trustee, 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. 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. Prior to May 28, 1999, the commitment fee
rate was 0.05%. The commitment fee is allocated among the funds based on their
respective average net assets for the period. During the year ended December 31,
1999, the Fund borrowed minimal amounts under the line of credit agreement.
Interest expense for the Fund for the year ended December 31, 1999 was $461.

NOTE 6-INVESTMENT SECURITIES

The aggregate amount of investment securities (other than short-term securities)
purchased and sold by the Fund during the year ended December 31, 1999 was
$112,320,103 and $112,820,490, respectively.
  The amount of unrealized appreciation (depreciation) of investment securities,
for tax purposes, as of December 31, 1999 was as follows:

                       INDEPENDENT AUDITORS' REPORT

                       The Board of Trustees and Shareholders of
                       AIM Municipal Bond Fund:

                       We have audited the accompanying statement of assets and
                       liabilities of AIM Municipal Bond Fund (a portfolio of
                       AIM Funds Group), including the schedule of investments,
                       as of December 31, 1999, and the related statement of
                       operations for the year then ended, the statement of
                       changes in net assets and the financial highlights for
                       each of the years in the five-year period then ended.
                       These financial statements and financial highlights are
                       the responsibility of the Fund's management. Our
                       responsibility is to express an opinion on these
                       financial statements and 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
                       financial highlights are free of material misstatement.
                       An audit includes examining, on a test basis, evidence
                       supporting the amounts and disclosures in the financial
                       statements. Our procedures included confirmation of
                       securities owned as of December 31, 1999, by
                       correspondence with the custodian 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 financial
                       highlights referred to above present fairly, in all
                       material respects, the financial position of AIM
                       Municipal Bond Fund as of December 31, 1999, the results
                       of its operations for the year then ended, the changes in
                       its net assets and the financial highlights for each of
                       the years in the five-year period then ended, in
                       conformity with generally accepted accounting principles.
