For shareholders who seek a high level of current income. The Fund invests in a
portfolio consisting primarily of high-yielding, lower-rated corporate bonds.

ABOUT FUND PERFORMANCE AND PORTFOLIO DATA THROUGHOUT THIS REPORT:

o   AIM High Yield Fund performance figures are historical and reflect
    reinvestment of all distributions and changes in net asset value. Unless
    otherwise indicated, the Fund's performance is computed at net asset value
    without a sales charge.
o   During the fiscal year ended December 31, 1998, the Fund paid distributions
    of $0.91 per share for Class A shares, $0.84 for Class B shares, and $0.84
    for Class C shares.
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 Class A shares due to differences in sales charge structure and
    class expenses.
o   The 30-day yield is calculated on the basis of 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 bonds in the portfolio,
    net of all expenses and expressed on an annualized basis. 
o   The Fund invests primarily in higher-yielding, lower-rated corporate bonds,
    commonly known as junk bonds. These bonds have a greater risk of price
    fluctuation and loss of principal and income than U.S. government
    securities, such as U.S. Treasury bonds and bills, which offer a government
    guarantee as to the repayment of principal and interest if held to maturity.
o   The Fund's Investment return and principal value will fluctuate so that an
    investor's shares, when redeemed, may be worth more or less than their
    original cost.

ABOUT INDEXES AND OTHER PERFORMANCE BENCHMARKS CITED IN THIS REPORT:

o   The C.S. First Boston High Yield Index tracks more than 270 segments within
    the high-yield universe and includes credit quality, industry, security
    type, and maturity.
o   The Lehman High Yield Bond Index is an unmanaged composite generally
    considered representative of high-yield debt securities. It is compiled by
    Lehman Brothers, a well-known global investment bank.
o   The unmanaged Lipper High Current Yield Fund Index represents an average of
    the performance of the 30 largest high-yield funds charted by Lipper, Inc.,
    an independent mutual fund performance monitor. Results shown reflect
    reinvestment of dividends.
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   An investment cannot be made in any index listed. 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 A PORTION OR ALL OF YOUR MONEY.

                       ANNUAL REPORT / CHAIRMAN'S LETTER



                    Dear Fellow Shareholder:

                    As the fiscal year opened, markets were recovering from the 
   [PHOTO OF        concerns produced by financial crises in Asia during 1997, 
  Charles T.        and this optimism early in 1998 led several equity market 
    Bauer           indexes to all-time highs in spring and early summer. 
 Chairman of        However, the year was to bring two particularly serious 
 the Board of       financial shocks, first the debt default by Russia, and 
   THE FUND         later the gathering crisis in Brazil, which devalued its 
 APPEARS HERE]      currency shortly after the fiscal year closed. The result 
                    was another year of significant volatility in both equity 
                    and fixed-income markets. 

                    MARKET RECAP 
                    Buoyant equity markets and healthy economic growth in Europe
                    and the U.S. kept bond prices relatively stable early in 
                    1998. But optimism turned to profound pessimism over the 
                    summer as global financial crises caused a worldwide loss of
confidence. Investors flocked to securities perceived as safe and liquid,
especially U.S. Treasuries. Even high-quality corporate bonds went out of favor,
and high-yield corporate bonds plummeted. Beginning in late September, the U.S.
Federal Reserve Board intervened to pump liquidity and confidence into markets.
Numerous interest rate cuts in other countries followed. Investors responded
favorably, and by year end, bond market volatility had generally subsided. 

HOW SHOULD INVESTORS RESPOND? 
We understood how unnerving 1998's level of volatility could have been. Our
repeated message to you is to keep a long-term outlook on investments rather
than responding to short-term fluctuations. And we are pleased to note that most
mutual fund shareholders remained cool headed and did not pull out of the
markets during 1998. In the end, most were rewarded for their long-term
perspective. 
    In view of recent volatility and the divergent performance of market 
sectors, this may be a very good time to meet with your financial consultant to
review your current asset allocation and the diversification of your portfolio.
Broad portfolio diversification remains one of the most fundamental principles
of investing, along with long-term thinking and realistic expectations. 

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

YEAR 2000 CONCERN 
Many of our shareholders have asked us about AIM's year 2000 readiness status.
We appreciate these concerns, and we take the year 2000 issue seriously. AIM has
devoted considerable effort to creating a comprehensive plan for assessing,
correcting and testing our in-house systems. We will also participate in an
industrywide testing effort scheduled to begin in March. But no matter how well
we prepare and test, no one can know for sure what the year 2000 will bring. Our
industry's systems are connected in complex ways to many third parties, and
there may be unforeseen problems when the year 2000 actually arrives. Though we
cannot predict what all those problems might be, we are working with our
business recovery team to develop contingency plans appropriate for a variety of
year 2000 problem scenarios. 
    We are pleased to send you this report on your Fund's fiscal year. If you 
have any questions or comments, please contact our Client Services department at
800-959-4246, or e-mail your inquiry to us at [email protected]. You can

                       ANNUAL REPORT / MANAGERS' OVERVIEW

FUND FOCUSES ON QUALITY IN DIFFICULT MARKET

THE MARKET EXPERIENCED ALL-TIME HIGHS AND ONE OF ITS MOST VICIOUS CORRECTIONS
DURING 1998. HOW DID AIM HIGH YIELD FUND PERFORM IN THIS UNSETTLING ENVIRONMENT?
We have been in a very challenging environment during the past year. The Fund
has suffered from a combination of oversupply and weakened demand, as well as
from the "flight to quality" following a succession of global currency crises.
Total returns for the fiscal year ended December 31, 1998, for Class A, Class B,
and Class C shares were -5.10%, -5.90%, -5.92%, respectively. 
    Despite the difficult high-yield market conditions in 1998 the Fund 
continued to provide attractive current income. As of December 30, 1998, the
Fund's 30-day SEC yields were 10.92%, 10.70%, and 10.70% for Class A, Class B,
and Class C shares, respectively. By comparison, the yield on the benchmark
30-year U.S. Treasury bond was 5.09%.
    During the reporting period, net assets under management grew approximately 
$150 million for a total of $3.61 billion at the close of the fiscal year. 

WHAT WERE THE MAJOR TRENDS IN THE FINANCIAL MARKETS SINCE YOUR JUNE REPORT TO
SHAREHOLDERS?
Beginning in July, markets succumbed to the second wave of "Asian contagion"
when currency troubles in Asia made their way to the United States. A month
later, Russia's bond default and the downturn that ensued involved even the very
large, very liquid stocks that were chiefly responsible for the U.S. markets'
earlier rise. Domestically, the markets were hit by the collapse of several
hedge funds. Investors sought shelter from market volatility in the safest and
most liquid investment classes, particularly large-cap equities and U.S.
Treasury securities. 
    The Federal Reserve Board (the Fed) announced the first of three interest 
rate cuts in September, hoping to shelter the U.S. from a potential global
recession. Boosted by the Fed easing, the U.S. markets rebounded and led the way
for recovery in many foreign markets. 

HOW DID HIGH-YIELD BONDS FARE IN THIS MARKET TURBULENCE? 
High-yield bonds were hit hard during the summer "flight to quality" when
investors turned to U.S. Treasury securities for their relative safety.
Beginning in August, investor demand did not keep up with record levels of new
high-yield offerings, generating broad-based volatility in the high-yield
market. As market volatility increased, the volume of new high-yield issues
dropped significantly as companies feared weakened demand. Performance of
many high-yield funds deteriorated significantly in the wake of falling
corporate profits and rising default rates. However, AIM High Yield Fund did not
suffer from any defaults during the reporting period.
    After a devastating third quarter, the worst in almost eight years, the
high-yield market began to recover, boosted by the Fed's interest rate cuts.
Liquidity slowly returned to the market, as new offerings reappeared. During
November, more than $2.5 billion in new corporate debt entered the market, led
by a group of fast-growing telecommunications companies. The spread between
high-yield

bonds and U.S. Treasury securities, which had reached its widest point since the
early 1990s, fell from 750 to 600 basis points as the high-yield market rallied.

GIVEN CURRENT MARKET CONDITIONS, HOW HAVE YOU MANAGED THE PORTFOLIO?
During the fourth quarter, as volatility in the high-yield market continued, we
focused on increasing quality in the Fund's portfolio. Volatility in the
high-yield market created some exceptional values in higher-quality debt. We
added more holdings in the higher-quality BB segment of the market which
accounted for 2.94% of the Fund's net assets in June. BB-rated bonds represented
7.83% of net assets as of December 31, 1998. 
    Conversely, we reduced the Fund's holdings in CCC and non-rated securities 
from 34.22% of net assets in June to 29.75% at the close of the fiscal year.
Overall, we maintained about 60% of the Fund's net assets in the single-B
sector, as rated by Standard & Poor's, a widely known credit-rating agency. 
    At the close of the fiscal year, the Fund's largest holdings were in the
telecommunications and broadcasting industries. These industries continue to
perform well despite weakening economic conditions. High-yield securities were
90.11% of the Fund's holdings, with approximately 7% of that figure invested in
foreign corporate debt. The Fund remained well diversified across 237 holdings
representing 62 industries. During the reporting period, we trimmed our holdings
in steel, shipping, and energy, as those industries continue to be hit hard by
battered commodity prices. 
    Our cash position at the close of the fiscal year was 4.40%. We aim to 
maintain the Fund's cash weighting around 5% to take advantage of new issues, as
the supply of high-yield issues is expected to increase at the beginning of
1999. 

WHAT IS YOUR OUTLOOK FOR 1999? 
By and large, we are optimistic that the U.S. market has performed a turnaround,
coming back from its steep declines last summer. Market analysts are optimistic
that the United States will avoid a recession in 1999. Economic growth seems to
be decelerating, so low inflation and low interest rates should continue. These
conditions may bode well for high-yield bonds in the coming year. 
    Historically, November to February is, on average, the best-performing 
period in the high-yield market, adding approximately 15% on an annualized
basis. With the yield spreads between high-yield bonds and 10-year U.S. Treasury
securities at their widest since 1991, many analysts believe that high-yield
bonds represent a good bargain for the near term. Investors may be rewarded by
the appreciation that should occur as yields return to more normal levels. 
    With a slowing economy expected in 1999, the key to continuing recovery in 
the high-yield market will be corporate earnings in the coming months. As the
rate of defaults continues to increase due to more volatile market conditions,
we believe that credit quality will become more of a differentiating factor in
total return performance. We remain focused on providing attractive current
income and on minimizing volatility within the Fund's portfolio as much as
possible.

ABOUT THESE CHARTS
These charts compare your Fund's Class A shares to benchmark indexes. They are
intended to give you a general idea of how your Fund performed compared to these
benchmarks over the period 12/31/88 to 12/31/98. It is important to understand
differences between your Fund and these indexes. An index measures performance
of a hypothetical portfolio. A market index such as the C.S. First Boston 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. An index of funds such as the Lipper
High Current Yield Fund Index includes a number of mutual funds grouped by
investment objective. Each of those funds interprets that objective differently,
and each employs a different management style and investment strategy. 
    Since the last reporting period, your Fund has elected to use the Lehman 
High Yield Bond Index.
This index more closely reflects the performance of securities in which the Fund
invests. The Fund will no longer be measured against the C.S. First Boston High
Yield Index. The Lipper High Current Yield Fund Index remains as one of the
Fund's benchmarks. 
    Because this is the first reporting period since we have adopted the new 
index, SEC guidelines require that we compare the Fund's performance to both the
old and new index.

WHAT DO BOND RATINGS MEAN?
The preceding discussion of your Fund's performance mentions the quality of the
bonds in the Fund's portfolio. Just what are bond quality ratings? 
    Two well-known rating agencies, Moody's and Standard & Poor's (S&P), assign 
ratings to bond issues. The chart shows a summary of the definitions of these
ratings. 

HOW BONDS ARE RATED 
Bond ratings are essentially based on the issuer's risk of default, or 
nonpayment of principal and/or interest, on the bond. How does a bond rating
come about? Say a company wants to raise $5 million for expansion by issuing a
five-year bond, meaning that in five years' time, the company will repay $5
million plus interest to the investor(s) in the bond issue. The company, or
issuer, pays a fee to have its bond rated by a qualified rating agency. The
selected rating agency sends representatives to the company to meet with
management and evaluate the company's short-and long-term risk profile--the
company's ability and willingness to pay the principal and interest of the bond
issue at its maturity, in this case five years. Other rating factors include: 

o   the make-up and terms of the particular issue;
o   the level and predictability of the issuer's cash flow;
o   how well-protected the issue is in the event of bankruptcy, reorganization
    or other arrangement;
o   possible adverse economic conditions both in general and in the company's
    sector; and
o   currency risk in the case of foreign issues.

    After considering these and any other factors deemed necessary by agency
representatives, the rating agency assigns a rating, such as "A," to the issue.
The rating is made public before the issue is offered to investors so that 
investors know the relative quality of the bond. Investors can then decide for 
themselves

if they wish to invest in a particular bond issue.

WHAT BOND RATINGS MEAN
Although the rating systems of the two agencies differ slightly, their hierarchy
is essentially the same: the highest rated bonds, Aaa for Moody's and AAA for
S&P, are those which show the best capacity for repayment of the principal (face
value) plus interest to the bondholder. These high-rated bonds have a lower
return because they are a lower-risk investment. In other words, rating and risk
and return move conversely for bonds--the lower the rating, the higher the
potential risk and return, and vice versa. So although investment grade bonds
such as U.S. Treasury issues are one of the safest investments around, more
speculative junk bonds can yield significantly higher returns if an investor can
tolerate the risk.
    Moody's and S&P sometimes use modifiers along with their standard ratings. 
Moody's may add a 1, 2 or 3 to a rating (e.g., Aa2), with a 1 denoting an issue
ranking in the higher end of its category, a 2 denoting a mid-range ranking, and
a 3 denoting a lower-end ranking. Similarly, S&P may add a plus (+) or minus (-)
to show an issue's relative standing within a category (e.g., B+). 
    Once assigned, bond ratings are not often altered. However, if major changes
occur in an issuer's short- or long-term credit outlook, a rating agency may
review the rating for possible modification. Contributing factors may include
shifts in industry demand, new technologies, government intervention, regulatory
changes, or changes in macroeconomic variables such as oil prices. Events such
as these are weighed to determine how much they will affect the issuer's
operations and future direction.

UNRATED BONDS
What about unrated bonds? Just because a bond is unrated does not mean it is a
"bad" bond. Some organizations simply choose not to pay to have their bonds
rated. Often the issuer of an unrated bond is a small entity such as a town or
district that does not have extra money to pay for a rating. In those cases,
independent research is necessary on the part of the investor to put together a
risk profile of the issuer.

NOTES TO FINANCIAL STATEMENTS
 
DECEMBER 31, 1998
 
NOTE 1-SIGNIFICANT ACCOUNTING POLICIES
 
AIM High Yield 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 series 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 and Class C shares are sold with a contingent deferred sales
charge. Matters affecting each portfolio or class are 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 objective is
to achieve a high level of current income by investing primarily in publicly
traded non-investment grade debt securities. The Fund will also consider the
possibility of capital growth when it purchases and sells securities. Debt
securities of less than investment grade are considered "high risk" securities
(commonly referred to as junk bonds). These bonds may involve special risks in
addition to the risks associated with investment in higher rated debt
securities. High yield bonds may be more susceptible to real or perceived
adverse economic and competitive industry conditions than higher grade bonds.
Also, the secondary market in which high yield bonds are traded may be less
liquid than the market for higher grade 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 significant accounting policies followed by the Fund
in the preparation of its financial statements.
 
A.  Security Valuations -- Debt securities (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
    institution-size trading in similar groups of securities, developments
    related to special securities, yield, quality, coupon rate, maturity, type
    of issue, individual trading characteristics and other market data.
    Investment securities for which prices are not provided by the pricing
    service and which are listed or traded on an exchange (except convertible
    bonds) are valued at the last sales price on the exchange where principally
    traded or, lacking any sales on a particular day, at the mean between the
    closing bid and asked prices on that day unless the Board of Trustees, or
    persons designated by the Board of Trustees, determines that
    over-the-counter
 
                                       16
<PAGE>   19
 
    quotations more closely reflect the current market value of the security.
    Securities traded in the over-the-counter market, except (i) securities
    priced by the pricing service, (ii) securities for which representative
    exchange prices are available, and (iii) securities reported in the NASDAQ
    National Market System, are valued at the mean between representative last
    bid and asked prices obtained from an electronic quotation reporting system,
    if such prices are available, or from established market makers. Each
    security reported in the NASDAQ National Market System is valued at the last
    sales price on the valuation date or absent a last sales price, at the mean
    between the closing bid and asked prices. 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. Short-term obligations having 60 days or less to maturity are
    valued at amortized cost which approximates market value.
B.  Securities Transactions, Investment Income and Distributions -- 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. It is the policy of the Fund to declare daily dividends
    from net investment income. Such dividends are paid monthly. Distributions
    from net realized capital gains, if any, are recorded on ex-dividend date
    and are paid annually subject to restrictions noted in section "C" below. On
    December 31, 1998 additional paid-in capital was decreased by $13,257,050,
    undistributed net investment income was increased by $148,371 and
    undistributed net realized gains was increased by $13,108,679 as a result of
    differing book/tax treatment of foreign currency transactions, market
    discount reclassifications and expirations of capital loss carryforwards in
    order to comply with the requirements of the American Institute of Certified
    Public Accountants Statement of Position 93-2. Net assets of the Fund were
    unaffected by the reclassifications discussed above.
C.  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 $118,664,039 (which may be carried forward to offset future
    taxable capital gains, if any) which expires, if not previously utilized,
    through the year 2006. The Fund cannot distribute capital gains to
    shareholders until the tax loss carryforwards have been utilized.
D.  Foreign Currency Translation -- 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.
E.  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 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.
F.  Expenses -- Distribution 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 0.625% of
the first $200 million of the Fund's average daily net assets, plus 0.55% of the
Fund's average daily net assets in excess of $200 million to and including $500
million, plus 0.50% of the Fund's average daily net assets in excess of $500
million to and including $1 billion, plus 0.45% of 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 reimburse AIM for certain administrative costs incurred in providing
accounting services to the Fund. During the year ended December 31, 1998, AIM
was reimbursed $135,537 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. During the year ended December 31, 1998, the
Fund paid AFS $2,794,049 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
distribution plans pursuant to Rule 12b-1 under the 1940 Act with respect to the
Fund's Class A shares and Class C shares (the "Class A and C Plan"), and the
Fund's Class B shares (the "Class B Plan") (collectively, the "Plans"). The
Fund, pursuant to the Class A and C Plan, pays AIM Distributors compensation at
an annual rate of 0.25% of the average daily net assets of the Class A shares
and 1.00% of the average daily net assets of the Class C shares. The Fund
pursuant to the Class B Plan, pays AIM Distributors compensation at an annual
rate of 1.00% of the average daily net assets of the Class B shares. Of these
amounts, the Fund may pay a service fee of 0.25% of the average daily net assets
of the Class A, 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 year ended December 31, 1998, the Class A, Class B and Class
C shares paid AIM Distributors $4,521,613, $18,264,587 and $760,766,
respectively, as compensation under the Plans.
  AIM Distributors received commissions of $1,822,464 from sales of the Class A
shares of the Fund during the year ended December 31, 1998. 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
 
                                       17
<PAGE>   20
 
December 31, 1998, AIM Distributors received $660,651 in contingent deferred
sales charges imposed on redemptions of Fund shares. Certain officers and
trustees of the Trust are officers and directors of AIM, AIM Distributors and
AFS.
  During the year ended December 31, 1998, the Fund paid legal fees of $10,514
for services rendered by Kramer, Levin, Naftalis & Frankel 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, 1998, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $41,157 and $175,918, respectively under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $217,075 during the year ended December 31, 1998.
 
NOTE 4-TRUSTEES' FEES
 
Trustees' fees represent remuneration paid or accrued to each trustee who is not
an "interested person" of AIM. The Trust may invest 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. Interest on
borrowings under the line of credit is payable on maturity or prepayment date.
Prior to an amendment of the line of credit on May 1, 1998, the Fund was limited
to borrowing up to the lesser of (i) $500,000,000 or (ii) the limits set by its
prospectus for borrowings. During the year ended December 31, 1998, the Fund did
not borrow under the line of credit agreement. The funds which are parties to
the line of credit are charged a commitment fee of 0.05% on the unused balance
of the committed line. The commitment fee is allocated among such funds based on
their respective average net assets for the period.

                       INDEPENDENT AUDITORS' REPORT
 
                       The Board of Trustees and Shareholders of
                       AIM High Yield Fund:
 
                       We have audited the accompanying statement of assets and
                       liabilities of AIM High Yield Fund (a portfolio of AIM
                       Funds Group), including the schedule of investments, as
                       of December 31, 1998, the related statement of operations
                       for the year then ended, the statement of changes in its
                       net assets for each of the years in the two-year period
                       then ended 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, 1998, 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 High
                       Yield Fund as of December 31, 1998, the results of its
                       operations for the year then ended, the changes in its
                       net assets for each of the years in the two-year period
                       then ended and the financial highlights for each of the
                       years in the five-year period then ended, in conformity
                       with generally accepted accounting principles.
