AIM ADVANTAGE HEALTH SCIENCES FUND SEEKS CAPITAL GROWTH.

.. Unless otherwise stated, information presented in this report is as of August
31, 2005, and is based on total net assets.

ABOUT SHARE CLASSES

.. Class B shares are not available as an investment for retirement plans
maintained pursuant to Section 401 of the Internal Revenue Code, including
401(k) plans, money purchase pension plans and profit sharing plans. Plans that
had existing accounts invested in Class B shares prior to September 30, 2003,
will continue to be allowed to make additional purchases.

PRINCIPAL RISKS OF INVESTING IN THE FUND

.. Investing in smaller companies involves greater risk than investing in more
established companies, such as business risk, significant stock price
fluctuations and illiquidity.

.. Investing in a single-sector or single-region mutual fund involves greater
risk and potential reward than investing in a more diversified fund.

.. The Fund is nondiversified, which increases risks as well as potential
rewards.

.. Portfolio turnover is greater than that of most funds, which may affect
performance.

.. The Fund seeks to participate in the initial public offering (IPO) market, and
a significant portion of the Fund's returns may be attributable to IPO
investments. While IPOs may significantly enhance Fund returns, there is no
guarantee that the market for these securities will continue to be robust. Also,
this type of security may have limited liquidity.

.. The Fund may invest 100% of its assets in the securities of non-U.S. issuers.
International investing presents certain risks not associated with investing
solely in the United States. These include risks relating to fluctuations in the
value of the U.S. dollar relative to the values of other currencies, the custody
arrangements made for the Fund's foreign holdings, differences in accounting,
political risks and the lesser degree of public information required to be
provided by non-U.S. companies.

.. Leveraging and short-selling, along with other hedging strategies, present
higher risks, but also offer greater potential rewards. Since stock prices can
rise without limit, short sales are riskier because of unlimited exposure to
loss until the position is covered. The Fund, which is not a complete investment
program, may not be appropriate for all investors. There is no guarantee that
the Fund managers' investment strategies will help investors attain their goals.
Please see the prospectus for more information about specific investment
strategies and risks.

.. The Fund may invest up to 15% of its assets in illiquid securities. The Fund's
investments include securities of privately held joint venture capital companies
which are considered to be illiquid. A security is considered to be illiquid if
the Fund is unable to sell such security at a fair price within a reasonable
amount of time. Investments in privately held joint venture capital securities
are inherently risky because the markets for these companies' products may never
materialize and the Fund could ultimately lose its entire investment.

ABOUT INDEXES USED IN THIS REPORT

.. The unmanaged LIPPER HEALTH/BIOTECH FUND INDEX represents an average of the 30
largest health and biotechnology funds tracked by Lipper, Inc., an independent
mutual fund performance monitor.

.. The MORGAN STANLEY HEALTH CARE PRODUCT INDEX is an equal-dollar weighted index
of companies involved in the business of pharmaceuticals, including
biotechnology and medical technology.

.. The unmanaged Standard & Poor's Composite Index of 500 Stocks (the S&P 500
- --REGISTERED TRADEMARK-- Index) is an index of common stocks frequently used as
a general measure of U.S. stock market performance.

.. A direct investment cannot be made in an index. Unless otherwise indicated,
index results include reinvested dividends, and they do not reflect sales
charges. Performance of an index of funds reflects fund expenses; performance of
a market index does not.

.. The Fund is not managed to track the performance of any particular index,
including the indexes defined here, and consequently, the performance of the
Fund may deviate significantly from the performance of the indexes.

OTHER INFORMATION

.. The returns shown in management's discussion of Fund performance are based on
net asset values calculated for shareholder transactions. Generally accepted
accounting principles require adjustments to be made to the net assets of the
Fund at period end for financial reporting purposes, and as such, the net asset
values for shareholder transactions and the returns based on those net asset
values may differ from the net asset values and returns reported in the
Financial Highlights.

.. Industry classifications used in this report are generally according to the
Global Industry Classification Standard, which was developed by and is the
exclusive property and a service mark of Morgan Stanley Capital International
Inc. and Standard & Poor's.

The Fund provides a complete list of its holdings four times in each fiscal
year, at the quarter-ends. For the second and fourth quarters, the lists appear
in the Fund's semiannual and annual reports to shareholders. For the first and
third quarters, the Fund files the lists with the Securities and Exchange
Commission (SEC) on Form N-Q. The most recent list of portfolio holdings is
available at AIMinvestments.com. From our home page, click on Products &
Performance, then Mutual Funds, then Fund Overview. Select your Fund from the

AIM ADVANTAGE HEALTH SCIENCES FUND

                    DEAR FELLOW AIM FUNDS SHAREHOLDERS:

                    The fiscal year ended August 31, 2005, was a good one for
                    investors as solid economic growth and generally impressive
                    company earnings offset concerns about rising oil prices and
                    the Federal Reserve's repeated increases in short-term
                    interest rates. Most equity indexes, both domestic and
                    international, ended up producing double-digit returns for
                    the fiscal year.

[GRAHAM PHOTO]        For a discussion of how market conditions affected your
                    Fund and how the Fund was managed during the fiscal year,
                    please turn to Page 3.

                    ADDITIONAL INFORMATION IN THIS REPORT

ROBERT H. GRAHAM      We would like to call your attention to two new elements
                    in this report on your Fund. First, on Page 2, is a letter
                    from Bruce Crockett, the independent Chair of the Board of
                    Trustees of the AIM Funds. We first introduced you to Mr.
                    Crockett in the annual report on your Fund dated September
                    30, 2004.

                      Mr. Crockett has been on our Funds' Board since 1992; he
                    assumed his responsibilities as Chair in October 2004.

[WILLIAMSON PHOTO]    Mr. Crockett has expressed an interest in keeping
                    shareholders informed of the work of the Board regularly via
                    letters in the Fund reports. We certainly consider this a
                    valuable addition to the reports. The Board is charged with
                    looking out for the interests of shareholders, and Mr.
                    Crockett's letter provides insight into some of the many
                    issues the Board addresses in governing your Fund.

MARK H. WILLIAMSON    One of the most important decisions the Board makes each
                    year is whether to approve the advisory agreement your Fund
                    has with AIM. Essentially, this agreement hires AIM to
                    manage the assets in your Fund. A discussion of the factors
                    the Board considered in reviewing the agreement is the
                    second new element in the report, and we encourage you to
                    read it. It appears on Pages 8 and 9.

                      Further information about the markets, your Fund, and
                    investing in general is always available on our widely
                    acclaimed Web site, AIMinvestments.com. We invite you to
                    visit it frequently.

                      We at AIM remain committed to building solutions to help
                    you meet your investment goals. We thank you for your

AIM ADVANTAGE HEALTH SCIENCES FUND

                    DEAR AIM FUNDS SHAREHOLDERS:

                    As independent Chair of the Board of Trustees of the AIM
                    Funds, I'm writing to report on the work being done by
                    your Board.

[CROCKETT PHOTO]      At our most recent meeting in June 2005, your Board
                    approved voluntary fee reductions from A I M Advisors, Inc.
                    (AIM) that save shareholders approximately $20.8 million
                    annually, based on asset levels as of March 31, 2005. The
                    majority of these expense reductions, which took effect July
                    1, 2005, will be achieved by a permanent reduction to 0.25%
                    of the Rule 12b-1 fees on Class A and Class A3 shares of
                    those AIM Funds that previously charged these fees at a
                    higher rate.

BRUCE L. CROCKETT     Our June meeting, which was the culmination of more than
                    two and one-half months of review and discussions, took
                    place over a three-day period. The meeting included your
                    Board's annual comprehensive evaluation of each fund's
                    advisory agreement with AIM. After this evaluation, in which
                    questions about fees, performance and operations were
                    addressed by AIM, your Board approved all advisory
                    agreements for the year beginning July 1, 2005. You can find
                    information on the factors considered and conclusions
                    reached by your Board in its evaluation of each fund's
                    advisory agreement at AIMinvestments.com. (Go to "Products &
                    Performance" and click on "Investment Advisory Agreement
                    Renewals.") The advisory agreement information about your
                    Fund is also included in this annual report on Pages 8 and
                    9. I encourage you to review it.

                      Together with monitoring fund expenses, fund performance
                    is your Board's priority. Our initial goal is to work
                    with AIM to bring about improvement in every AIM Fund
                    that has been underperforming its category.

                      Your Board has a well-defined process and structure for
                    monitoring all funds and identifying and assisting AIM in
                    improving underperforming funds. Our Investments
                    Committee--which functions along with Audit, Governance,
                    Valuation and Compliance Committees--is the only one of
                    these five standing committees to include all 13 independent
                    Board members. Further, our Investments Committee is divided
                    into three underlying subcommittees, each responsible for,
                    among other things, reviewing the performance, fees and
                    expenses of the funds that have been assigned to it.

                      At subcommittee meetings, held throughout the year, the
                    performance of every AIM Fund is evaluated. If a fund has
                    underperformed its peer group for a meaningful period, we
                    work closely with AIM to discover the causes and help
                    develop the right responses. In some cases, AIM may
                    determine that a change in portfolio management strategy or
                    portfolio managers is required. In other cases, where a fund
                    no longer seems viable, it may be merged with a similar
                    fund, being careful to consider the needs of all
                    shareholders affected by the decision. Following AIM's
                    recommendation and your Board's approval, eight funds were
                    recently merged.

                      Be assured that your Board is working closely with the
                    management of AIM to help you reach your investment goals.
                    Should you or your advisor have questions or comments about
                    the governance of AIM Funds, I invite you to write to me at
                    AIM Investments, AIM Investments Tower, 11 Greenway Plaza,
                    Suite 100, Houston, TX 77046. Your Board looks forward to
                    keeping you informed about the governance of your funds.

                    Sincerely,

                    /s/ BRUCE L. CROCKETT

AIM ADVANTAGE HEALTH SCIENCES FUND

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
- --------------------------------------------------------------------------------

PERFORMANCE SUMMARY

We are pleased to report that for the fiscal year ended August 31, 2005, Class A
shares of AIM Advantage Health Sciences Fund returned 18.35% at net asset value,
outperforming the broad market. We believe this outperformance was due to
general strength in the health care sector and particular strength in health
care services stocks and managed care stocks.

     Your Fund also outperformed its style-specific index. We attribute its
outperformance to its health care services holdings, which performed well in
advance of the Medicare Modernization Act, which will offer Medicare recipients
insurance coverage for their prescription drugs. The index had no exposure to
health care services stocks.

HOW WE INVEST

We seek health care stocks of all market capitalizations we believe are
attractively priced and have the potential to benefit from long-term earnings
and cash flow growth.

     We typically invest in four segments of the health care sector:
pharmaceuticals, bio-technology, medical technology and health care services. We
look for companies that are financially healthy and, in our opinion, likely to
sustain their profitability. We assess the long-term commercial potential of
each company's current and prospective products, especially products that meet
otherwise unfilled market needs.

     In addition, we may "short" stocks--borrowing a stock when we believe it is
likely to decline in value, later repurchasing it and replacing it at a lower
price, allowing us to profit from the decline. We may, for example, short stocks
of companies that our research suggests are facing product obsolescence.

     The Fund's investments also include securities of privately held venture
capital companies considered illiquid.

     We seek to manage risk by generally:

.. limiting investments in a single stock

.. diversifying across industries

.. monitoring political trends that could negatively affect a specific industry

     We may sell a holding when:

.. we find a more attractive investment

.. we see a deterioration of a company's fundamentals

.. a company fails to capitalize on a market opportunity

.. a change in management occurs

MARKET CONDITIONS AND YOUR FUND

In July, U.S. Federal Reserve Board Chairman Alan Greenspan reported that "our
baseline outlook for the U.S. economy is one of sustained economic growth and
contained inflation pressures." The biggest potential threats to continued
economic expansion were rising short-term interest rates and rising energy
prices. But because most health care spending is not dependent on economic
conditions, the health care sector was less affected by these trends than were
some other sectors.

     As a group, health care stocks within the S&P 500 Index provided high
single-digit returns for the fiscal year, underperforming the index as a whole.
Nonetheless, many investors favored health care stocks--both because they are
less sensitive to the economy and because many larger, more established

                                                                     (continued)

health care companies pay relatively attractive dividends. We share the view
that regardless of short-term economic conditions, the health care sector is
likely to benefit from an aging population over the long term.

     For the fiscal year, health care services and managed health care stocks
were among the sector's strongest performers. Factors contributing to their
positive performance included:

.. aggressive cost cutting

.. continued pricing power

.. growing membership as unemployment declined

     Also, investors recognized the likely positive impact of the Medicare
Modernization Act on such companies when that law becomes effective in January
2006. PacifiCare and Community Health Systems were among the health care
services and managed health care holdings that contributed to Fund performance
during the reporting period. PacifiCare, for example, has long been regarded as
a well-managed industry leader, but its stock got an added boost when the
company announced in July that it would merge with UnitedHealth Group (not a
Fund holding).

     Biotechnology stocks performed quite well over the year, particularly
stocks of larger and more established biotech companies. Reasons for their
strength included strong revenue and earnings growth, positive clinical trial
data for new drugs designed to treat underserved diseases and conditions, and
heightened merger activity initiated by several large-cap pharmaceutical
companies. Over the year, we increased our biotech holdings.

     Because individual biotech stocks can be volatile, as the fiscal year drew
to a close we began increasing our "short" exposure to the biotech industry. We
believe this strategy helps reduce your Fund's volatility. In considering
whether or not to short a stock, we looked for near-term catalysts that we
believed were likely to send a stock's price lower--catalysts including drug
approval timelines, releases of clinical trial data and earnings.

     Among the biotech stocks we shorted during the fiscal year were Cephalon
and Onyx Pharmaceuticals. Cephalon, a biopharmaceutical company, faces upcoming
patent expirations for two of its three biggest products: sleep-disorder drug
Provigil and pain-management drug Actiq. Onyx Pharmaceuticals' lead drug
candidate, Sorafenib, is currently in phase III clinical development. We
believed the potential for positive news about the drug was already priced into
the stock. By the end of the fiscal year, we closed out our position in both of
these stocks and no longer held them in the portfolio.

     In contrast to biotech stocks, many large-cap pharmaceutical stocks
continued to perform poorly. While pharmaceutical stocks benefited from the
rotation into defensive growth stocks during the reporting period, they were
hindered by concerns about patent expirations, restructuring initiatives and a
dearth of promising new "blockbuster" products in their pipelines. As a result,
pharmaceutical stocks, which accounted for almost 40% of Fund assets at the
close of the fiscal year, had only a marginal negative effect on Fund
performance.

     The performance of individual pharmaceutical stocks varied widely because
of company-specific news. Roche Holding and Protein Design Labs benefited from
their collaboration with Genentech (not a Fund holding) on a promising new
cancer drug, Avastin; Roche owns 56% of Genentech. Forest Labs hindered Fund
performance due to increasing generic competition and because its product
pipeline appears to have faltered. As a result, we reduced our exposure to
Forest Labs before the close of the fiscal year.

IN CLOSING
We remain optimistic about the potential of the health care sector, given
demographic trends and people's desire to prolong and improve the quality of
their lives. As always, we thank you for your continued investment in AIM
Advantage Health Sciences Fund.

AIM ADVANTAGE HEALTH SCIENCES FUND

CALCULATING YOUR ONGOING FUND EXPENSES

EXAMPLE
As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, which may include sales charges (loads) on purchase payments; contingent
deferred sales charges on redemptions; and redemption fees, if any; and (2)
ongoing costs, including management fees; distribution and/or service fees
(12b-1); and other Fund expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with ongoing costs of investing in other mutual funds. The
example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period March 1, 2005, through August 31, 2005.

ACTUAL EXPENSES
The table below provides information about actual account values and actual
expenses. You may use the information in this table, together with the amount
you invested, to estimate the expenses that you paid over the period. Simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Actual Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The table below also provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The Fund's actual cumulative total returns at net asset value after
expenses for the six months ended August 31, 2005, appear in the table
"Cumulative Total Returns" on Page 7.

     The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period. You may
use this information to compare the ongoing costs of investing in the Fund and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

     Please note that the expenses shown in the table are meant to highlight
your ongoing costs only and do not reflect any transactional costs, such as
sales charges (loads) on purchase payments, contingent deferred sales charges on
redemptions, and redemption fees, if any. Therefore, the hypothetical
information is useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

                                       ACTUAL                        HYPOTHETICAL
                                                            (5% ANNUAL RETURN BEFORE EXPENSES)

/1/ The actual ending account value is based on the actual total return of the
Fund for the period March 1, 2005, through August 31, 2005, after actual
expenses and will differ from the hypothetical ending account value which is
based on the Fund's expense ratio and a hypothetical annual return of 5% before
expenses. The Fund's actual cumulative total returns at net asset value after
expenses for the six months ended August 31, 2005, appear in the table
"Cumulative Total Returns" on Page 7.

/2/ Expenses are equal to the Fund's annualized expense ratio (2.62%, 3.30% and
3.30% for Class A, B and C shares, respectively) multiplied by the average
account value over the period, multiplied by 184/365 (to reflect the one-half
year period). Effective on July 1, 2005, the distributor contractually agreed to
reduce rule 12B-1 plan fees for Class A shares to 0.25%. The annualized expense
ratio restated as if the agreement had been in effect throughout the entire most
recent fiscal half year is 2.55% for Class A shares.

/3/ The actual expenses paid restated as if the change discussed above had been
in effect throughout the most recent fiscal half year are $13.70 for Class A
shares.

/4/ The hypothetical expenses paid restated as if the change discussed above had
been in effect throughout the most recent fiscal half year are $12.93 for Class
A shares.

The data shown in the chart include reinvested distributions, applicable sales
charges, Fund expenses and management fees. Index results include reinvested
dividends, but they do not reflect sales charges. Performance of an index of
funds reflects fund expenses and management fees; performance of a market index
does not. Performance shown in the chart and table(s) does not reflect deduction
of taxes a shareholder would pay on Fund distributions or sale of Fund shares.
Performance of the indexes does not reflect the effects of taxes.

This chart, which is a logarithmic chart, presents the fluctuations in the value
of the Fund and its indexes. We believe that a logarithmic chart is more
effective than other types of charts in illustrating changes in value during the
early years shown in the chart. The vertical axis, the one that indicates the
dollar value of an investment, is constructed with each segment representing a
percent change in the value of the investment. In this chart, each segment
represents a doubling, or 100% change, in the value of the investment. In other
words, the space between $5,000 and $10,000 is the same size as between $10,000
and $20,000.

AIM ADVANTAGE HEALTH SCIENCES FUND

APPROVAL OF INVESTMENT ADVISORY AGREEMENT AND
SUMMARY OF INDEPENDENT WRITTEN FEE EVALUATION

The Board of Trustees of AIM Counselor Series Trust (the "Board") oversees the
management of AIM Advantage Health Sciences Fund (the "Fund") and, as required
by law, determines annually whether to approve the continuance of the Fund's
advisory agreement with A I M Advisors, Inc. ("AIM"). Based upon the
recommendation of the Investments Committee of the Board, which is comprised
solely of independent trustees, at a meeting held on June 30, 2005, the Board,
including all of the independent trustees, approved the continuance of the
advisory agreement (the "Advisory Agreement") between the Fund and AIM for
another year, effective July 1, 2005.

The Board considered the factors discussed below in evaluating the fairness and
reasonableness of the Advisory Agreement at the meeting on June 30, 2005 and as
part of the Board's ongoing oversight of the Fund. In their deliberations, the
Board and the independent trustees did not identify any particular factor that
was controlling, and each trustee attributed different weights to the various
factors.

One of the responsibilities of the Senior Officer of the Fund, who is
independent of AIM and AIM's affiliates, is to manage the process by which the
Fund's proposed management fees are negotiated to ensure that they are
negotiated in a manner which is at arm's length and reasonable. To that end, the
Senior Officer must either supervise a competitive bidding process or prepare an
independent written evaluation. The Senior Officer has recommended an
independent written evaluation in lieu of a competitive bidding process and,
upon the direction of the Board, has prepared such an independent written
evaluation. Such written evaluation also considered certain of the factors
discussed below. In addition, as discussed below, the Senior Officer made
certain recommendations to the Board in connection with such written evaluation.

The discussion below serves as a summary of the Senior Officer's independent
written evaluation and recommendations to the Board in connection therewith, as
well as a discussion of the material factors and the conclusions with respect
thereto that formed the basis for the Board's approval of the Advisory
Agreement. After consideration of all of the factors below and based on its
informed business judgment, the Board determined that the Advisory Agreement is
in the best interests of the Fund and its shareholders and that the compensation
to AIM under the Advisory Agreement is fair and reasonable and would have been
obtained through arm's length negotiations.

.. The nature and extent of the advisory services to be provided by AIM. The
Board reviewed the services to be provided by AIM under the Advisory Agreement.
Based on such review, the Board concluded that the range of services to be
provided by AIM under the Advisory Agreement was appropriate and that AIM
currently is providing services in accordance with the terms of the Advisory
Agreement.

.. The quality of services to be provided by AIM. The Board reviewed the
credentials and experience of the officers and employees of AIM who will provide
investment advisory services to the Fund. In reviewing the qualifications of AIM
to provide investment advisory services, the Board reviewed the qualifications
of AIM's investment personnel and considered such issues as AIM's portfolio and
product review process, various back office support functions provided by AIM
and AIM's equity and fixed income trading operations. Based on the review of
these and other factors, the Board concluded that the quality of services to be
provided by AIM was appropriate and that AIM currently is providing satisfactory
services in accordance with the terms of the Advisory Agreement.

.. The performance of the Fund relative to comparable funds. The Board reviewed
the performance of the Fund during the past one, three and five calendar years
against the performance of funds advised by other advisors with investment
strategies comparable to those of the Fund. The Board noted that the Fund's
performance in such periods was below the median performance of such comparable
funds. The Board also noted that AIM began serving as investment advisor to the
Fund in November 2003. The Board noted that AIM has recently made changes to the
Fund's portfolio management team, which appear to be producing encouraging early
results but need more time to be evaluated before a conclusion can be made that
the changes have addressed the Fund's under-performance. Based on this review,
the Board concluded that no changes should be made to the Fund and that it was
not necessary to change the Fund's portfolio management team at this time.

.. The performance of the Fund relative to indices. The Board reviewed the
performance of the Fund during the past one, three and five calendar years
against the performance of the Lipper Health/Biotech Fund Index. The Board noted
that the Fund's performance in such periods was below the performance of such
Index. The Board also noted that AIM began serving as investment advisor to the
Fund in November 2003. The Board noted that AIM has recently made changes to the
Fund's portfolio management team, which appear to be producing encouraging early
results but need more time to be evaluated before a conclusion can be made that
the changes have addressed the Fund's under-performance. Based on this review,
the Board concluded that no changes should be made to the Fund and that it was
not necessary to change the Fund's portfolio management team at this time.

.. Meeting with the Fund's portfolio managers and investment personnel. With
respect to the Fund, the Board is meeting periodically with such Fund's
portfolio managers and/or other investment personnel and believes that such
individuals are competent and able to continue to carry out their
responsibilities under the Advisory Agreement.

.. Overall performance of AIM. The Board considered the overall performance of
AIM in providing investment advisory and portfolio administrative services to
the Fund and concluded that such performance was satisfactory.

.. Fees relative to those of clients of AIM with comparable investment
strategies. The Board noted that AIM does not serve as an advisor to other
mutual funds or other clients with investment strategies comparable to those of
the Fund.

.. Fees relative to those of comparable funds with other advisors. The Board
reviewed the advisory fee rate for the Fund under the Advisory Agreement. The
Board noted that the Fund's advisory fee is structured as a fulcrum fee, with a
base component and a performance adjustment component. The Board compared
effective contractual advisory fee rates at a common asset level and noted that
the Fund's rate was above the median rate of the funds advised by other advisors
with investment strategies comparable to those of the Fund that the Board
reviewed. The Board noted that none of the advisory fees for these other funds
were structured as fulcrum fees. The Board noted that AIM has agreed to waive
advisory fees of the Fund, as discussed below. Based on this review, the Board
concluded that the advisory fee rate for the Fund under the Advisory Agreement
was fair and reasonable.

.. The Board noted that AIM has contractually agreed to waive advisory fees to
the extent necessary such that the advisory fee AIM receives does not exceed an
annual base management fee of 1.25%, subject to a maximum annual performance
adjustment upward or downward of 0.75%, through June 30, 2006. As a result of
this waiver, the Board noted that the net advisory fees are limited to a maximum
of 2.00% and a minimum of 0.50%. The Board considered the contractual nature of
this fee waiver and noted that it remains in effect until June 30, 2006. The
Board considered the effect this fee waiver would have on the Fund's estimated
expenses and concluded that the levels of fee waivers/expense limitations for
the Fund were fair and reasonable.

.. Breakpoints and economies of scale. The Board reviewed the structure of the
Fund's advisory fee under the Advisory Agreement, noting that it does not
include any breakpoints. The Board considered whether it would be appropriate to
add advisory fee breakpoints for the Fund or whether, due to the nature of the
Fund and the advisory fee structures of comparable funds, it was reasonable to
structure the advisory fee without breakpoints. Based on this review, the Board
concluded that it was not necessary to add advisory fee breakpoints to the
Fund's advisory fee schedule. The Board reviewed the level of the Fund's
advisory fees, and noted that such fees, as a percentage of the Fund's net
assets, would remain constant under the Advisory Agreement because the Advisory
Agreement does not include any breakpoints. The Board concluded that the Fund's
fee levels under the Advisory Agreement therefore would not reflect economies of
scale.




AIM ADVANTAGE HEALTH SCIENCES FUND

.. Investments in affiliated money market funds. The Board also took into account
the fact that uninvested cash and cash collateral from securities lending
arrangements (collectively, "cash balances") of the Fund may be invested in
money market funds advised by AIM pursuant to the terms of an SEC exemptive
order. The Board found that the Fund may realize certain benefits upon investing
cash balances in AIM advised money market funds, including a higher net return,
increased liquidity, increased diversification or decreased transaction costs.
The Board also found that the Fund will not receive reduced services if it
invests its cash balances in such money market funds. The Board noted that, to
the extent the Fund invests in affiliated money market funds, AIM has
voluntarily agreed to waive a portion of the advisory fees it receives from the
Fund attributable to such investment. The Board further determined that the
proposed securities lending program and related procedures with respect to the
lending Fund is in the best interests of the lending Fund and its respective
shareholders. The Board therefore concluded that the investment of cash
collateral received in connection with the securities lending program in the
money market funds according to the procedures is in the best interests of the
lending Fund and its respective shareholders.

.. Independent written evaluation and recommendations of the Fund's Senior
Officer. The Board noted that, upon their direction, the Senior Officer of the
Fund, who is independent of AIM and AIM's affiliates, had prepared an
independent written evaluation in order to assist the Board in determining the
reasonableness of the proposed management fees of the AIM Funds, including the
Fund. The Board noted that the Senior Officer's written evaluation had been
relied upon by the Board in this regard in lieu of a competitive bidding
process. In determining whether to continue the Advisory Agreement for the Fund,
the Board considered the Senior Officer's written evaluation and the
recommendation made by the Senior Officer to the Board that the Board consider
implementing a process to assist them in more closely monitoring the performance
of the AIM Funds. The Board concluded that it would be advisable to implement
such a process as soon as reasonably practicable.

.. Profitability of AIM and its affiliates. The Board reviewed information
concerning the profitability of AIM's (and its affiliates') investment advisory
and other activities and its financial condition. The Board considered the
overall profitability of AIM, as well as the profitability of AIM in connection
with managing the Fund. The Board noted that AIM's operations remain profitable,
although increased expenses in recent years have reduced AIM's profitability.
Based on the review of the profitability of AIM's and its affiliates' investment
advisory and other activities and its financial condition, the Board concluded
that the compensation to be paid by the Fund to AIM under its Advisory Agreement
was not excessive.

.. Benefits of soft dollars to AIM. The Board considered the benefits realized by
AIM as a result of brokerage transactions executed through "soft dollar"
arrangements. Under these arrangements, brokerage commissions paid by the Fund
and/or other funds advised by AIM are used to pay for research and execution
services. This research is used by AIM in making investment decisions for the
Fund. The Board concluded that such arrangements were appropriate.

.. AIM's financial soundness in light of the Fund's needs. The Board considered
whether AIM is financially sound and has the resources necessary to perform its
obligations under the Advisory Agreement, and concluded that AIM has the
financial resources necessary to fulfill its obligations under the Advisory
Agreement.

.. Historical relationship between the Fund and AIM. In determining whether to
continue the Advisory Agreement for the Fund, the Board also considered the
prior relationship between AIM and the Fund, as well as the Board's knowledge of
AIM's operations, and concluded that it was beneficial to maintain the current
relationship, in part, because of such knowledge. The Board also reviewed the
general nature of the non-investment advisory services currently performed by
AIM and its affiliates, such as administrative, transfer agency and distribution
services, and the fees received by AIM and its affiliates for performing such
services. In addition to reviewing such services, the trustees also considered
the organizational structure employed by AIM and its affiliates to provide those
services. Based on the review of these and other factors, the Board concluded
that AIM and its affiliates were qualified to continue to provide non-investment
advisory services to the Fund, including administrative, transfer agency and
distribution services, and that AIM and its affiliates currently are providing
satisfactory non-investment advisory services.

.. Other factors and current trends. In determining whether to continue the
Advisory Agreement for the Fund, the Board considered the fact that AIM, along
with others in the mutual fund industry, is subject to regulatory inquiries and
litigation related to a wide range of issues. The Board also considered the
governance and compliance reforms being undertaken by AIM and its affiliates,
including maintaining an internal controls committee and retaining an
independent compliance consultant, and the fact that AIM has undertaken to cause
the Fund to operate in accordance with certain governance policies and
practices. The Board concluded that these actions indicated a good faith effort
on the part of AIM to adhere to the highest ethical standards, and determined
that the current regulatory and litigation environment to which AIM is subject
should not prevent the Board from continuing the Advisory Agreement for the
Fund.

NOTES TO FINANCIAL STATEMENTS
August 31, 2005

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

AIM Advantage Health Sciences Fund, formerly INVESCO Advantage Health Sciences
Fund, (the "Fund") is a series portfolio of AIM Counselor Series Trust (the
"Trust"). The Trust is a Delaware statutory trust registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of two separate portfolios,
each authorized to issue an unlimited number of shares of beneficial interest.
The Fund currently offers multiple classes of shares. 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 seek capital growth.
  Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. However, the Fund has not had prior claims or losses pursuant to
these contracts.
  The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including
estimates and assumptions related to taxation. 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.

                                      F-7




A. SECURITY VALUATIONS -- Securities, including restricted securities, are
   valued according to the following policy.
     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 traded in the over-the-counter market (but
   not securities reported on the NASDAQ National Market System) is valued on
   the basis of prices furnished by independent pricing services, which may be
   considered fair valued, or market makers. Each security reported on the
   NASDAQ National Market System is valued at the NASDAQ Official Closing Price
   ("NOCP") as of the close of the customary trading session on the valuation
   date or absent a NOCP, at the closing bid price.
     Futures contracts are valued at the final settlement price set by an
   exchange on which they are principally traded. Listed options are valued at
   the mean between the last bid and the ask prices from the exchange on which
   they are principally traded. Options not listed on an exchange are valued by
   an independent source at the mean between the last bid and ask prices. 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").
     Investments in open-end registered investment companies and closed-end
   registered investment companies that do not trade on an exchange are valued
   at the end of day net asset value per share. Investments in closed-end
   registered investment companies that trade on an exchange are valued at the
   last sales price as of the close of the customary trading session on the
   exchange where the security is principally traded.
     Debt obligations (including convertible bonds) are fair valued using an
   evaluated quote provided by an independent pricing service. Evaluated quotes
   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 specific securities, dividend rate, yield, quality, type of
   issue, coupon rate, maturity, individual trading characteristics and other
   market data. Short-term obligations having 60 days or less to maturity and
   commercial paper are valued at amortized cost which approximates market
   value.
     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.
     Foreign securities (including foreign exchange contracts) are converted
   into U.S. dollar amounts using the applicable exchange rates as of the close
   of the 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 the close of the respective markets.
   Events affecting the values of such foreign securities may occur between the
   times at which the particular foreign market closes and the close of the
   customary trading session of the NYSE which would not ordinarily be
   reflected in the computation of the Fund's net asset value. If the event is
   likely to have affected the closing price of the security, the security will
   be valued at fair value in good faith using procedures approved by the Board
   of Trustees. Adjustments to closing prices to reflect fair value may also be
   based on a screening process of an independent pricing service to indicate
   the degree of certainty, based on historical data, that the closing price in
   the principal market where a foreign security trades is not the current
   market value as of the close of the NYSE. Foreign securities meeting the
   approved degree of certainty that the price is not reflective of current
   market value will be priced at the indication of fair value from the
   independent pricing service. Multiple factors may be considered by the
   independent pricing service in determining adjustments to reflect fair value
   and may include information relating to sector indices, ADRs and domestic
   and foreign index futures.
     Securities for which market quotations are not readily available or are
   unreliable are valued at fair value as determined in good faith by or under
   the supervision of the Trust's officers following procedures approved by the
   Board of Trustees. Issuer specific events, market trends, bid/ask quotes of
   brokers and information providers and other market data may be reviewed in
   the course of making a good faith determination of a security's fair value.
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 on the accrual basis from settlement date.
   Dividend income is recorded on the ex-dividend date. Bond premiums and
   discounts are amortized and/or accreted for financial reporting purposes.
     Brokerage commissions and mark ups are considered transaction costs and
   are recorded as an increase to the cost basis of securities purchased and/or
   a reduction of proceeds on a sale of securities. Such transaction costs are
   included in the determination of realized and unrealized gain (loss) from
   investment securities reported in the Statement of Operations and the
   Statement of Changes in Net Assets and the realized and unrealized net gains
   (losses) on securities per share in the Financial Highlights. Transaction
   costs are included in the calculation of the Fund's net asset value and,
   accordingly, they reduce the Fund's total returns. These transaction costs
   are not considered operating expenses and are not reflected in net
   investment income reported in the Statement of Operations and Statement of
   Changes in Net Assets, or the net investment income per share and ratios of
   expenses and net investment income reported in the Financial Highlights, nor
   are they limited by any expense limitation arrangements between the Fund and
   the advisor.
     The Fund allocates income and realized and unrealized capital gains and
   losses to a class based on the relative net assets of each class.
     Cash and cash equivalents in the Statement of Cash Flows are comprised of
   cash and investments in affiliated money market funds for the purpose of
   investing daily available cash balances.
C. COUNTRY DETERMINATION -- For the purposes of making investment selection
   decisions and presentation in the Schedule of Investments, AIM may determine
   the country in which an issuer is located and/or credit risk exposure based
   on various factors. These factors include the laws of the country under
   which the issuer is organized, where the issuer maintains a principal
   office, the country in which the issuer derives 50% or more of its total
   revenues and the country that has the primary market for the issuer's
   securities, as well as other criteria. Among the other criteria that may be
   evaluated for making this determination are the country in which the issuer
   maintains 50% or more of its assets, the type of security, financial
   guarantees and enhancements, the nature of the collateral and the sponsor
   organization. Country of issuer and/or credit risk exposure has been
   determined to be United States of America unless otherwise noted.
D. DISTRIBUTIONS -- Distributions from income and net realized capital gain, 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.

                                      F-8




E. FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
   Subchapter M 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
   gain) which is distributed to shareholders. Therefore, no provision for
   federal income taxes is recorded in the financial statements.
F. EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
   class of the Fund and which are directly attributable to that class are
   charged to the operations of such class. All other expenses are allocated
   among the classes based on relative net assets.
G. CASH AND CASH EQUIVALENTS -- Cash and cash equivalents in the Statement of
   Cash Flows are comprised of cash and investments in affiliated money market
   funds for the purpose of investing daily available cash balances.
H. SECURITIES SOLD SHORT -- The Fund may enter into short sales of securities
   which it concurrently holds (against the box) or for which it holds no
   corresponding position (naked). Securities sold short represent a liability
   of the Fund to acquire specific securities at prevailing market prices at a
   future date in order to satisfy the obligation to deliver the securities
   sold. The liability is recorded on the books of the Fund at the market value
   of the common stock determined each day in accordance with the procedures
   for security valuations disclosed in "A" above. The Fund will incur a loss
   if the price of the security increases between the date of the short sale
   and the date on which the Fund replaces the borrowed security. The Fund
   realizes a gain if the price of the security declines between those dates.
     The Fund is required to segregate cash or securities as collateral in
   margin accounts at a level that is equal to the obligation to the broker who
   delivered such securities to the buyer on behalf of the Fund. The short
   stock rebate presented in the Statement of Operations represents the net
   income earned on short sale proceeds held on deposit with the broker and
   margin interest earned or incurred on short sale transactions. The Fund may
   also earn or incur margin interest on short sales transactions. Margin
   interest is the income earned (or expense incurred) as a result of the
   market value of securities sold short being less than (or greater than) the
   proceeds received from the short sales.
I. FOREIGN CURRENCY TRANSLATIONS -- Foreign currency is valued at the close of
   the NYSE based on quotations posted by banks and major currency dealers.
   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 (net of foreign taxes withheld
   on disposition) 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 the 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. The combined results of changes in foreign exchange rates
   and the fluctuation of market prices on investments (net of estimated
   foreign tax withholding) are included with the net realized and unrealized
   gain or loss from investments in the Statement of Operations. Reported net
   realized foreign currency gains or losses arise from (i) sales of foreign
   currencies, (ii) currency gains or losses realized between the trade and
   settlement dates on securities transactions, and (iii) the difference
   between the amounts of dividends, interest, and foreign withholding taxes
   recorded on the Fund's books and the U.S. dollar equivalent of the amounts
   actually received or paid. Net unrealized foreign currency gains and losses
   arise from changes in the fair values of assets and liabilities, other than
   investments in securities at fiscal period end, resulting from changes in
   exchange rates.
J. 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.
K. COVERED CALL OPTIONS -- The Fund may write and buy call options, including
   securities index options. 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 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 risk in writing a call
   option is that the Fund gives up the opportunity for profit if the market
   price of the security increases and the option is exercised.
     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.
     An option on a securities index gives the holder the right to receive a
   cash "exercise settlement amount" equal to the difference between the
   exercise price of the option and the value of the underlying stock index on
   the exercise date, multiplied by a fixed "index multiplier." A securities
   index fluctuates with changes in the market values of the securities
   included in the index. In the purchase of securities index options, the
   principal risk is that the premium and transaction costs paid by the Fund in
   purchasing an option will be lost if the changes in the level of the index
   do not exceed the cost of the option. In writing securities index options,
   the principal risk is that the Fund could bear a loss on the options that
   would be only partially offset (or not offset at all) by the increased value
   or reduced cost of hedged securities. Moreover, in the event the Fund was
   unable to close an option it had written, it might be unable to sell the
   securities used as cover.

                                      F-9




L. 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. A risk in
   buying an option is that the Fund pays a premium whether or not the option
   is exercised. In addition, there can be no assurance that a liquid secondary
   market will exist for any option purchased or sold.
M. VENTURE CAPITAL INVESTMENTS -- The Fund has invested in non-publicly traded
   companies, some of which are in the startup or development stages. These
   investments are inherently risky, as the markets for the technologies or
   products these companies are developing are typically in the early stages
   and may never materialize. The Fund could lose its entire investment in
   these companies. These investments are valued at fair value as determined in
   good faith in accordance with procedures approved by the Board of Trustees.
   Investments in privately held venture capital securities are illiquid.
N. COLLATERAL -- To the extent the Fund has pledged or segregated a security as
   collateral and that security is subsequently sold, it is the Fund's practice
   to replace such collateral no later than the next business day. This
   practice does not apply to securities pledged as collateral for securities
   lending transactions.

NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the investment advisory agreement,
the Fund pays a base management fee calculated at the annual rate of 1.50% of
the Fund's average daily net assets. The base management fee will be adjusted
on a monthly basis by a calculated rate ("Fee Adjustment Rate") (i) upward at
the rate of 0.20%, on a pro rata basis, for each percentage point the
investment performance of the Class A shares of the Fund for the previous 12
month period ("Performance Period") exceeds the sum of 2.00% plus the
investment record of the Morgan Stanley Health Care Product Index for the
Performance Period, but shall be capped at 2.50% of the Fund's average daily
net assets for the fiscal period, or (ii) downward at the rate of 0.20%, on a
pro rata basis, for each percentage point the investment record of the Morgan
Stanley Health Care Product Index for the Performance Period less 2.00% exceeds
the investment performance of the Class A shares of the Fund for the
Performance Period, but shall be no less than 0.50% of the average daily net
assets for the fiscal period. After the Fee Adjustment Rate is determined, AIM
will determine the dollar amount of additional fees or fee reductions to be
accrued for each day of a month by multiplying the Fee Adjustment Rate by the
average daily net assets of the Class A shares of the Fund during the
Performance Period and dividing the number by the number of days in the
Performance Period. The management fee, as adjusted, is accrued daily and paid
monthly. AIM has contractually agreed to waive advisory fees to the extent
necessary such that the advisory fee AIM receives does not exceed an annual
base management fee of 1.25%, subject to an annual maximum of 0.75% performance
adjustment upward or downward, through June 30, 2006 calculated in the same
manner as described above. As a result of this waiver, the net advisory fees
are limited to a maximum of 2.00% and a minimum of 0.50%. Under the terms of a
master sub-advisory agreement between AIM and INVESCO Institutional (N.A.),
Inc. ("INVESCO"), AIM paid INVESCO 40% of the fee paid by the Fund to AIM. This
sub-advisory agreement expired on September 30, 2004.
  Further, AIM has voluntarily agreed to waive advisory fees of the Fund in the
amount of 25% of the advisory fee AIM receives from the affiliated money market
funds on investments by the Fund in such affiliated money market funds
(excluding investments made in affiliated money market funds with cash
collateral from securities loaned by the fund). AIM is also voluntarily waiving
a portion of the advisory fee payable by the Fund equal to the difference
between the income earned from investing in the affiliated money market fund
and the hypothetical income earned from investing in an appropriate comparative
benchmark. Voluntary fee waivers or reimbursements may be modified or
discontinued at any time upon consultation with the Board of Trustees without
further notice to investors. Under the terms of the advisory agreement, the
Fund is not permitted to pay management fees on those assets of the Fund that
are invested in other funds advised by AIM.
  For the year ended August 31, 2005, AIM waived fees and/or reimbursed
expenses in the amount of $386,451.
  At the request of the Trustees of the Trust, AMVESCAP PLC ("AMVESCAP") agreed
to reimburse expenses incurred by the Fund in connection with market timing
matters in the AIM Funds, which may include legal, audit, shareholder
reporting, communications and trustee expenses. These expenses along with the
related expense reimbursement, are included in the Statement of Operations. For
the year ended August 31, 2005, AMVESCAP reimbursed expenses of the Fund in the
amount of $32,412.
  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. Pursuant to such agreement, for the year ended
August 31, 2005, AIM was paid $50,000.
  The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer agency
and shareholder services to the Fund and reimburse AISI for certain expenses
incurred by AISI in the course of providing such services. AISI may make
payments to intermediaries that provide omnibus account services,
sub-accounting services and/or networking services. For the year ended
August 31, 2005, the Fund paid AISI $296,166.
  The Trust has entered into master distribution agreements with A I M
Distributors, Inc. ("ADI") 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, Class B and Class
C shares (collectively the "Plans"). The Fund, pursuant to the Plans, pays ADI
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
Class C shares. Prior to July 1, 2005, the Fund paid ADI 0.35% of the average
daily net assets of Class A shares. Of these amounts, up to 0.25% of the
average daily net assets of the Class A, Class B or Class C shares may be paid
to furnish continuing personal shareholder services to customers who purchase
and own shares of such classes. Any amounts not paid as a service fee under the
Plans would constitute an asset-based sales charge. National Association of
Securities Dealers ("NASD") Rules also impose a cap on the total sales charges,
including asset-based sales charges that may be paid by any class of shares of
the Fund. Pursuant to the Plans, for the year ended August 31, 2005, the
Class A, Class B and Class C shares paid $510,831, $10,938 and $3,553,
respectively.
  Front-end sales commissions and contingent deferred sales charges ("CDSC")
(collectively the "sales charges") are not recorded as expenses of the Fund.
Front-end sales commissions are deducted from proceeds from the sales of Fund
shares prior to investment in Class A shares of the Fund. CDSC are deducted
from redemption proceeds prior to remittance to the shareholder. For the year
ended August 31, 2005, ADI advised the Fund that it retained $5,474 in
front-end sales

                                     F-10




commissions from the sale of Class A shares and $1, $2,203 and $49 from
Class A, Class B and Class C shares, respectively, for CDSC imposed upon
redemptions by shareholders.
  Certain officers and trustees of the Trust are officers and directors of AIM,
AISI, INVESCO and/or ADI.

NOTE 3--INVESTMENTS IN AFFILIATES

INVESTMENTS IN OTHER AFFILIATES:

The Investment Company Act of 1940 defines affiliates as those companies in
which a fund holds 5% or more of the outstanding voting securities. The Fund
has not owned enough of the outstanding voting securities of the issuer to have
control (as defined in the Investment Company Act of 1940) of that issuer. The
following is a summary of the transactions with affiliates for the year ended
August 31, 2005.

NOTE 4--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the
Board of Trustees of the Trust. The procedures have been designed to ensure
that any purchase or sale of securities by the Fund from or to another fund or
portfolio that is or could be considered an affiliate by virtue of having a
common investment advisor (or affiliated investment advisors), common Trustees
and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as
defined under the procedures, each transaction is effected at the current
market price. Pursuant to these procedures, during the year ended August 31,
2005, the Fund engaged in securities purchases of $3,463,421 and sales of
$510,247, which resulted in net realized gains of $111,104.

NOTE 5--EXPENSE OFFSET ARRANGEMENT

The expense offset arrangement is comprised of transfer agency credits which
result from balances in Demand Deposit Accounts (DDA) used by the transfer
agent for clearing shareholder transactions. For the year ended August 31,
2005, the Fund received credits from this arrangement, which resulted in the
reduction of the Fund's total expenses of $4,028.

NOTE 6--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees
who also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to fund such retirement benefits. Obligations under the deferred compensation
and retirement plans represent unsecured claims against the general assets of
the Fund.
  During the year ended August 31, 2005, the Fund paid legal fees of $4,518 for
services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 7--BORROWINGS

Effective November 1, 2004, the Fund entered into a committed line of credit
facility with a syndicate administered by JP Morgan Chase Bank. The Fund may
borrow up to the lesser of (i) $225,000,000 (ii) the limits set by its
prospectus for borrowings. As amended on August 23, 2005, the Fund may borrow
up to the lesser of (i) $255,000,000 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. During the year ended August 31,
2005, the Fund had average borrowings for the 304 days the borrowings were
outstanding, in the amount of $24,000,000 with a weighted average interest rate
of 3.54% and interest expense of 707,254.
  Prior to November 1, 2004, the Fund was a participant in a committed line of
credit facility with a syndicate administered by Citibank, N.A. The Fund may
borrow up to the lesser of (i) $100,000,000 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
0.10% on the unused balance of the committed line. During the year ended
August 31, 2005, the Fund had average borrowings for the 61 days the borrowings
were outstanding, in the amount of $23,852,459 with a weighted average interest
rate of 2.48% and interest expense of $98,893.
  Pursuant to an exemptive order from the SEC, the Fund may participate in an
interfund lending facility that AIM has established for temporary borrowings by
the AIM Funds. An interfund loan will be made under this facility only if the
loan rate (an average of the rate available on bank loans and the rate
available on investments in overnight repurchase agreements) is favorable to
both the lending fund and the borrowing fund. A loan will be secured by
collateral if the Fund's aggregate borrowings from all sources exceeds 10% of
the Fund's total assets. To the extent that the loan is required to be secured
by collateral, the collateral is marked to market daily to ensure that the
market value is at least 102% of the outstanding principal value of the loan.
During the year ended August 31, 2005, the Fund did not borrow or lend under
the interfund lending facility.
  Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with SSB, the custodian bank. To compensate
the custodian bank for such overdrafts, the overdrawn Fund may either (i) leave
funds as a compensating balance in the account so the custodian can be
compensated by earning the additional interest; or (ii) compensate by paying
the custodian bank at a rate agreed upon by the custodian bank and AIM, not to
exceed the rate contractually agreed upon.

NOTE 8--PORTFOLIO SECURITIES LOANED

The Fund may lend portfolio securities having a market value up to one-third of
the Fund's total assets. Such loans are secured by collateral equal to no less
than the market value of the loaned securities determined daily. Such
collateral will be cash or debt securities issued or guaranteed by the U.S.
Government or any of its agencies. Cash collateral received in connection with
these loans is invested in short-term money market instruments or affiliated
money market funds. It is the Fund's policy to obtain additional collateral
from or return excess collateral to the borrower by the end of the next
business day, following the valuation date of the securities loaned. Therefore,
the value of the collateral held may be temporarily less than the value of the
securities on loan. Lending securities entails a risk of loss to the Fund if
and to the extent that the market value of the securities loaned were to
increase and the borrower did not increase the collateral accordingly, and the
borrower fails to return the securities. The Fund could also experience delays
and costs in gaining access to the collateral. The Fund bears the risk of any
deficiency in the amount of the collateral available for return to the borrower
due to a loss on the collateral invested.

                                     F-12




NOTE 8--PORTFOLIO SECURITIES LOANED-(CONTINUED)

  At August 31, 2005, securities with an aggregate value of $4,071,724 were on
loan to brokers. The loans were secured by cash collateral of $4,085,119
received by the Fund and subsequently invested in an affiliated money market
fund. For the year ended August 31, 2005, the Fund received dividends on cash
collateral of $6,687 for securities lending transactions, which are net of
compensation to counterparties.

NOTE 10--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS

There were no ordinary income or long-term capital gain distributions paid
during the years ended August 31, 2005 and 2004.

TAX COMPONENTS OF NET ASSETS:

As of August 31, 2005, the components of net assets on a tax basis were as
follows:



                                                                 2005
       ------------------------------------------------------------------
                                                          
       Undistributed appreciation (depreciation)-investments   3,097,025
       ------------------------------------------------------------------
       Temporary book/tax differences                            (19,052)
       ------------------------------------------------------------------
       Capital loss carryforward                              (5,262,663)
       ------------------------------------------------------------------
       Shares of beneficial interest                         156,637,305
       ------------------------------------------------------------------
       Total net assets                                      154,452,615
       ------------------------------------------------------------------

  The difference between book-basis and tax-basis unrealized appreciation
(depreciation) is due to differences in the timing of recognition of gains and
losses on investments for tax and book purposes. The Fund's unrealized
appreciation (depreciation) difference is attributable primarily to the
deferral of losses on wash sales. The tax-basis unrealized appreciation
(depreciation) on investments amount includes appreciation (depreciation) on
foreign currencies of $(16,899), remaining proceeds to be received on security
buyout of $221,807 and an allowance for doubtful receipts of $70,982.
  The temporary book/tax differences are a result of timing differences between
book and tax recognition of income and/or expenses. The Fund's temporary
book/tax differences are the result of the trustee deferral of compensation and
retirement plan expenses.
  Capital loss carryforward is calculated and reported as of a specific date.
Results of transactions and other activity after that date may affect the
amount of capital loss carryforward actually available for the Fund to utilize.
The ability to utilize capital loss carryforward in the future may be limited
under the Internal Revenue Code and related regulations based on the results of
future transactions.
  The Fund utilized $17,835,053 of capital loss carryforward in the current
period to offset net realized capital gain for federal income tax purposes. The
Fund has a capital loss carryforward as of August 31, 2005 which expires as
follows:



                                         CAPITAL LOSS
                         EXPIRATION      CARRYFORWARD*
                         -----------------------------
                                      
                         August 31, 2011  $5,262,663
                         -----------------------------


*Capital loss carryforward as of the date listed above is reduced for
         limitations, if any, to the extent required by the Internal Revenue
         Code.

                                     F-13





NOTE 11--INVESTMENT SECURITIES

The aggregate amount of investment securities (other than short-term securities
and money market funds) purchased and sold by the Fund during the year ended
August 31, 2005 was $222,324,657 and $267,596,799, respectively.
  The receivable for investments sold is net of an allowance for doubtful
receipts of $70,982 for Norian Corp.-Series D, convertible preferred shares.
  At the request of the Trustee, AIM recovered third party research credits,
during the year ended August 31, 2005, in the amount of $37,038. These research

Net unrealized appreciation (depreciation) of investment securities   (2,963,099)
- ---------------------------------------------------------------------------------


Cost of investments for tax purposes is $175,908,522.
Proceeds from securities sold short for investment purposes are $8,515,039.

NOTE 12--RECLASSIFICATION OF PERMANENT DIFFERENCES

Primarily as a result of differing book/tax treatment of foreign currency
transactions, redomestication costs, certain dividends on short sales and net
operating losses, on August 31, 2005, undistributed net investment income
(loss) was increased by $2,284,028, undistributed net realized gain (loss) was
decreased by $19,516 and shares of beneficial interest decreased by $2,264,512.
This reclassification had no effect on the net assets of the Fund.

NOTE 13--SHARE INFORMATION

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 CDSC. Under
certain circumstances, Class A shares are subject to CDSC. Generally, Class B
shares will automatically convert to Class A shares eight years after the end
of the calendar month of purchase.

/(a)/Calculated using average shares outstanding.
/(b)/The net investment income (loss) per share was calculated after permanent
     book tax differences, such as net operating losses, which were
     reclassified from accumulated net investment income (loss) to paid in
     capital. Had net investment income (loss) per share been calculated using

     lawsuit against Oxford Health Plans, Inc. Net gains (losses) on securities
     (both realized and unrealized) per share and total return excluding these
     proceeds would have been $2.64 and 17.63%, respectively.
/(d)/Includes adjustments in accordance with accounting principles generally
     accepted in the United States of America and as such, the net asset value
     for financial reporting purposes and the returns based upon those net
     asset values may differ from the net asset value and returns for
     shareholder transactions. Does not include sales charges and is not
     annualized for periods less than one year.

SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Half of this amount has
already been paid to the fair fund pursuant to the terms of the settlement with
the remainder due December 31, 2005. Additionally, AIM and ADI created a $50
million fair fund ($30 million of which is civil penalties) to compensate
shareholders harmed by market timing and related activity in funds advised by
AIM, which was done pursuant to the terms of the settlement. These two fair
funds may increase as a result of contributions from third parties who reach
final settlements with the SEC or other regulators to resolve allegations of
market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a
methodology to be determined by AIM's independent distribution consultant, in
consultation with AIM and the independent trustees of the AIM Funds and
acceptable to the staff of the SEC. As the methodology is unknown at the
present time, management of AIM and the Fund are unable to estimate the impact,
if any, that the distribution of these two fair funds may have on the Fund or
whether such distribution will have an impact on the Fund's financial
statements in the future.
  At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.

NOTE 15--LEGAL PROCEEDINGS-(CONTINUED)

REGULATORY INQUIRIES AND PENDING LITIGATION

  IFG, AIM, ADI and/or related entities and individuals have received inquiries
from numerous regulators in the form of subpoenas or other oral or written
requests for information and/or documents related to one or more of the
following issues, some of which concern one or more AIM Funds: market timing
activity, late trading, fair value pricing, excessive or improper advisory
and/or distribution fees, mutual fund sales practices, including revenue
sharing and directed-brokerage arrangements, investments in securities of other
registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost
securityholders. IFG, AIM and ADI are providing full cooperation with respect
to these inquiries. As described more fully below, the AIM Funds, IFG, AIM, ADI
and/or related entities and individuals are defendants in numerous civil
lawsuits related to one or more of these issues. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.
  On April 12, 2005, the Attorney General of the State of West Virginia
("WVAG") filed a civil lawsuit against AIM, IFG and ADI, as well as numerous
unrelated mutual fund complexes and financial institutions. None of the AIM
Funds has been named as a defendant in this lawsuit. The WVAG complaint, filed
in the Circuit Court of Marshall County, West Virginia [Civil Action
No. 05-C-81], alleges, in substance, that AIM, IFG and ADI engaged in unfair
competition and/or unfair or deceptive trade practices by failing to disclose
in the prospectuses for the AIM Funds, including those formerly advised by IFG,
that they had entered into certain arrangements permitting market timing of
such Funds. As a result of the foregoing, the WVAG alleges violations of W. Va.
Code (S) 46A-1-101, et seq. (the West Virginia Consumer Credit and Protection
Act). The WVAG complaint is seeking, among other things, injunctive relief,
civil monetary penalties and a writ of quo warranto against the defendants. If
AIM is unsuccessful in its defense of the WVAG lawsuit, it could be barred from
serving as an investment advisor for any investment company registered under
the Investment Company Act of 1940, as amended (a "registered investment
company"). Such results could affect the ability of AIM or any other investment
advisor directly or indirectly owned by AMVESCAP, from serving as an investment
advisor to any registered investment company, including the Fund. The Fund has
been informed by AIM that, if these results occur, AIM will seek exemptive
relief from the SEC to permit it to continue to serve as the Fund's investment
advisor. There is no assurance that such exemptive relief will be granted. On
July 7, 2005, the Supreme Court of West Virginia ruled in the context of a
separate lawsuit that the WVAG does not have authority pursuant to W. Va. Code
Section 46A-6-104 of the West Virginia Consumer Credit and Protection Act to
bring an action based upon conduct that is ancillary to the purchase or sale of
securities. AIM intends to seek dismissal of the WVAG's lawsuit against it, IFG
and ADI in light of this ruling.
  On August 30, 2005, the West Virginia Office of the State Auditor--Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI. The WVASC makes findings of fact that
essentially mirror the WVAG's allegations mentioned above and conclusions of
law to the effect that AIM and ADI violated the West Virginia securities laws.
The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions to be determined by the Commissioner. AIM and ADI
have the right to contest the WVASC's findings and conclusions, which they
intend to do.
  Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:
     .   that the defendants permitted improper market timing and related
         activity in the AIM Funds;
     .   that certain AIM Funds inadequately employed fair value pricing;
     .   that the defendants charged excessive advisory and/or distribution
         fees and failed to pass on to shareholders the perceived savings
         generated by economies of scale and that the defendants adopted
         unlawful distribution plans;
     .   that the defendants breached their fiduciary duties by charging
         distribution fees while AIM Funds and/or specific share classes were
         closed generally to new investors and/or while other share classes of
         the same AIM Fund were not charged the same distribution fees;
     .   that the defendants improperly used the assets of the AIM Funds to pay
         brokers to aggressively promote the sale of the AIM Funds over other
         mutual funds and that the defendants concealed such payments from
         investors by disguising them as brokerage commissions; and
     .   that the defendants breached their fiduciary duties by failing to
         ensure that the AIM Funds participated in class action settlements in
         which they were eligible to participate (this lawsuit was dismissed by
         the Court on August 12, 2005).

These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.
  All lawsuits based on allegations of market timing, late trading and related
activity have been transferred to the United States District Court for the
District of Maryland. On August 25, 2005, the Court issued rulings on the
common issues of law presented in defendants' motions to dismiss the
shareholder class and derivative complaints. These rulings were issued in the
context of the Janus lawsuits, but the Court's legal determinations apply at
the omnibus level to all cases within his track, including the AIM and IFG
cases. The Court dismissed for failure to make pre-suit demand on the fund
board all derivative causes of action but one: the excessive fee claim under
Section 36(b) of the Investment Company Act of 1940 (the "1940 Act"), as to
which the demand requirement does not apply. The Court dismissed all claims
asserted in the class complaint but two: (i) the securities fraud claims under
Section 10(b) of the Securities Exchange Act of 1934, and (ii) the excessive
fee claim under Section 36(b) of the 1940 Act. In addition, the Court limited
plaintiffs' potential recovery on the 36(b) claim to fees attributable to
timing assets, as opposed to all fees on funds in which any timing occurred.
The question whether the duplicative Section 36(b) claim properly belongs in
the derivative complaint or in the class action complaint will be decided at a
later date. The Court will subsequently issue an order applying his legal
rulings to the allegations in the AIM and IFG complaints.

NOTE 15--LEGAL PROCEEDINGS-(CONTINUED)

  At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Regulatory Inquiries and Pending
Litigation described above may have on AIM, ADI or the Fund.

As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees
and Shareholders of AIM Advantage Health Sciences Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations, of
changes in net assets and of cash flows and the financial highlights present
fairly, in all material respects, the financial position of AIM Advantage
Health Sciences Fund, formerly known as INVESCO Advantage Health Sciences Fund,
(one of the funds constituting AIM Counselor Series Trust, hereafter referred
to as the "Fund") at August 31, 2005, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended, the cash flows for the period then ended and the financial
highlights for each of the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at August 31, 2005 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

AIM MULTI-SECTOR FUND SEEKS CAPITAL GROWTH.

.. Unless otherwise stated, information presented in this report is as of August
31, 2005, and is based on total net assets.

ABOUT SHARE CLASSES

.. Class B shares are not available as an investment for retirement plans
maintained pursuant to Section 401 of the Internal Revenue Code, including
401(k) plans, money purchase pension plans and profit sharing plans. Plans that
had existing accounts invested in Class B shares prior to September 30, 2003,
will continue to be allowed to make additional purchases.

PRINCIPAL RISKS OF INVESTING IN THE FUND

.. Investing in smaller companies involves greater risk than investing in more
established companies, such as business risk, significant stock price
fluctuations and illiquidity.

.. The Fund may invest up to 25% of its assets in the securities of non-U.S.
issuers. Securities of Canadian issuers and American Depositary Receipts are not
subject to this 25% limitation. International investing presents certain risks
not associated with investing solely in the United States. These include risks
relating to fluctuations in the value of the U.S. dollar relative to the values
of other currencies, the custody arrangements made for the Fund's foreign
holdings, differences in accounting, political risks and the lesser degree of
public information required to be provided by non-U.S. companies.

.. Investing in a mutual fund with a higher concentration of sectors involves
greater risks and potential rewards than investing in a more diversified fund.

ABOUT INDEXES USED IN THIS REPORT

.. The unmanaged Lipper MULTI-CAP CORE FUND INDEX represents an average of the
performance of the 30 largest multi-capitalization core funds tracked by
Lipper, Inc., an independent mutual fund performance monitor.

.. The unmanaged Standard & Poor's Composite Index of 500 Stocks (the S&P 500
- --REGISTERED TRADEMARK-- Index) is an index of common stocks frequently used as
a general measure of U.S. stock market performance.

.. A direct investment cannot be made in an index. Unless otherwise indicated,
index results include reinvested dividends, and they do not reflect sales
charges. Performance of an index of funds reflects fund expenses; performance of
a market index does not.

.. The Fund is not managed to track the performance of any particular index,
including the indexes defined here, and consequently, the performance of the
Fund may deviate significantly from the performance of the indexes.

OTHER INFORMATION

.. The returns shown in management's discussion of Fund performance are based on
net asset values calculated for shareholder transactions. Generally accepted
accounting principles require adjustments to be made to the net assets of the
Fund at period end for financial reporting purposes, and as such, the net asset
values for shareholder transactions and the returns based on those net asset
values may differ from the net asset values and returns reported in the
Financial Highlights.

.. Industry classifications used in this report are generally according to the
Global Industry Classification Standard, which was developed by and is the
exclusive property and a service mark of Morgan Stanley Capital International
Inc. and Standard & Poor's.

.. The Fund provides a complete list of its holdings four times in each fiscal
year, at the quarter-ends. For the second and fourth quarters, the lists appear
in the Fund's semiannual and annual reports to share-holders. For the first and
third quarters, the Fund files the lists with the Securities and Exchange
Commission (SEC) on Form N-Q. The most recent list of portfolio holdings is
available at AIMinvestments.com. From our home page, click on Products &
Performance, then Mutual Funds, then Fund Overview. Select your Fund from the
drop-down menu and click on Complete Quarterly Holdings. Shareholders can also
look up the Fund's Forms N-Q on the SEC's Web site at sec.gov. And copies of the
Fund's Forms N-Q may be reviewed and copied at the SEC's Public Reference Room
at 450 Fifth Street, N.W., Washington, D.C. 20549-0102. You can obtain
information on the operation of the Public Reference Room, including information

file numbers for the Fund are 811-09913 and 333-36074.

to vote proxies relating to portfolio securities is available without charge,
upon request, from our Client Services department at 800-959-4246 or on the AIM
Web site, AIMinvestments.com. On the home page, scroll down and click on AIM

AIM MULTI-SECTOR FUND

                    DEAR FELLOW AIM FUNDS SHAREHOLDERS:

[GRAHAM PHOTO]      The fiscal year ended August 31, 2005, was a good one for
                    investors as solid economic growth and generally impressive
                    company earnings offset concerns about rising oil prices and
                    the Federal Reserve's repeated increases in short-term
                    interest rates. Most equity indexes, both domestic and
                    international, ended up producing double-digit returns for
                    the fiscal year.

                      For a discussion of how market conditions affected your
                    Fund and how the Fund was managed during the fiscal year,
                    please turn to Page 3.

                    ADDITIONAL INFORMATION IN THIS REPORT

ROBERT H. GRAHAM    We would like to call your attention to two new elements in
                    this report on your Fund. First, on Page 2, is a letter from
                    Bruce Crockett, the independent Chair of the Board of
                    Trustees of the AIM Funds. We first introduced you to Mr.
                    Crockett in the annual report on your Fund dated September
                    30, 2004. Mr. Crockett has been on our Funds' Board since
                    1992; he assumed his responsibilities as Chair in October
                    2004.

[WILLIAMSON PHOTO]    Mr. Crockett has expressed an interest in keeping
                    shareholders informed of the work of the Board regularly via
                    letters in the Fund reports. We certainly consider this a
                    valuable addition to the reports. The Board is charged with
                    looking out for the interests of shareholders, and Mr.
                    Crockett's letter provides insight into some of the many
                    issues the Board addresses in governing your Fund.

MARK H. WILLIAMSON    One of the most important decisions the Board makes each
                    year is whether to approve the advisory agreement your Fund
                    has with AIM. Essentially, this agreement hires AIM to
                    manage the assets in your Fund. A discussion of the factors
                    the Board considered in reviewing the agreement is the
                    second new element in the report, and we encourage you to
                    read it. It appears on Pages 9 and 10.

AIM MULTI-SECTOR FUND

                    DEAR AIM FUNDS SHAREHOLDERS:

                    As independent Chair of the Board of Trustees of the AIM
                    Funds, I'm writing to report on the work being done by your
                    Board.

[CROCKETT PHOTO]      At our most recent meeting in June 2005, your Board
                    approved voluntary fee reductions from A I M Advisors, Inc.
                    (AIM) that save shareholders approximately $20.8 million
                    annually, based on asset levels as of March 31, 2005. The
                    majority of these expense reductions, which took effect July
                    1, 2005, will be achieved by a permanent reduction to 0.25%
                    of the Rule 12b-1 fees on Class A and Class A3 shares of
                    those AIM Funds that previously charged these fees at a
                    higher rate.

BRUCE L. CROCKETT     Our June meeting, which was the culmination of more than
                    two and one-half months of review and discussions, took
                    place over a three-day period. The meeting included your
                    Board's annual comprehensive evaluation of each fund's
                    advisory agreement with AIM. After this evaluation, in which
                    questions about fees, performance and operations were
                    addressed by AIM, your Board approved all advisory
                    agreements for the year beginning July 1, 2005. You can find
                    information on the factors considered and conclusions
                    reached by your Board in its evaluation of each fund's
                    advisory agreement at AIMinvestments.com. (Go to "Products &
                    Performance" and click on "Investment Advisory Agreement
                    Renewals.") The advisory agreement information about your
                    Fund is also included in this annual report on Pages 9 and
                    10. I encourage you to review it.

                      Together with monitoring fund expenses, fund performance
                    is your Board's priority. Our initial goal is to work with
                    AIM to bring about improvement in every AIM Fund that has
                    been underperforming its category.

                      Your Board has a well-defined process and structure for
                    monitoring all funds and identifying and assisting AIM in
                    improving underperforming funds. Our Investments
                    Committee--which functions along with Audit, Governance,
                    Valuation and Compliance Committees--is the only one of
                    these five standing committees to include all 13 independent
                    Board members. Further, our Investments Committee is divided
                    into three underlying subcommittees, each responsible for,
                    among other things, reviewing the performance, fees and
                    expenses of the funds that have been assigned to it.

                      At subcommittee meetings, held throughout the year, the
                    performance of every AIM Fund is evaluated. If a fund has
                    underperformed its peer group for a meaningful period, we
                    work closely with AIM to discover the causes and help
                    develop the right responses. In some cases, AIM may
                    determine that a change in portfolio management strategy or
                    portfolio managers is required. In other cases, where a fund
                    no longer seems viable, it may be merged with a similar
                    fund, being careful to consider the needs of all
                    shareholders affected by the decision. Following AIM's
                    recommendation and your Board's approval, eight funds were
                    recently merged.

                      Be assured that your Board is working closely with the
                    management of AIM to help you reach your investment goals.
                    Should you or your advisor have questions or comments about
                    the governance of AIM Funds, I invite you to write to me at
                    AIM Investments, AIM Investments Tower, 11 Greenway Plaza,
                    Suite 100, Houston, TX 77046. Your Board looks forward to
                    keeping you informed about the governance of your funds.

                    Sincerely,

                    /s/ BRUCE L. CROCKETT

AIM MULTI-SECTOR FUND

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
- --------------------------------------------------------------------------------

PERFORMANCE SUMMARY

We are pleased to report that for the fiscal year ended August 31, 2005, Class A
shares of AIM Multi-Sector Fund returned 28.01% at net asset value.

Your Fund handily outperformed the S&P 500 Index, which returned 12.55%. The
Fund's overweight position in energy stocks was its greatest contributor to its
outperformance relative to the broad market. Solid stock selection allowed your
Fund to significantly outperform the S&P 500 Index in each of the five sectors
in which it invests, as shown in the table on Page 4.

HOW WE INVEST

Your Fund invests the bulk of its assets in stocks from five market sectors:
energy, financials, health care, information technology and "leisure"
(represented by the consumer discretionary sector). Fund assets are divided
approximately equally among securities of companies in each sector to provide
diversification. Fund managers act independently, creating portfolios for each
sector that are applications of our best ideas in existing AIM sector funds.

     Managers use quantitative measures in stock selection combined with
insights from fundamental research to determine if a stock has value and strong
anticipated growth relative to its peers. We focus on companies that exhibit
strong return on capital, cash flow, sustainable growth, and superior business
strategies that make them market leaders.

     In the resulting portfolios, each sector has approximately 20 to 25
holdings. Your Fund is rebalanced annually at fiscal year-end to return the
sectors to their approximate equal weightings.

     We consider selling a stock when we see:

..  fundamental deterioration in the company

..  more attractive investment opportunities

..  inability of the company to capitalize on market opportunity

..  a questionable change in management's strategic direction

MARKET CONDITIONS AND YOUR FUND

Throughout the fiscal year, the economy expanded, driven largely by sustained,
robust consumer spending. At its close, inflation (excluding energy) remained
modest and payrolls continued to expand. In testimony to Congress in late July,
U.S. Federal Reserve Board (the Fed) Chairman Alan Greenspan suggested such
trends were likely to continue when he reported that "our baseline outlook for
the U.S. economy is one of sustained economic growth and contained inflation
pressures."

     Higher short-term interest rates and rising energy prices were the most
significant headwinds for the U.S. economy and the broad stock market. In an
effort to ensure that inflation remained contained, the Fed raised its federal
funds target rate from 1.50% at the start of the fiscal year to 3.50% at its
close. Its actions caused credit card interest rates, for example, to rise for
many consumers. Together, these two factors had the potential to crimp consumer
spending and slow economic growth.

     As the fiscal year drew to a close, we began to see signs that historically
high energy prices might finally be causing consumers to reduce

their spending. In late August, Hurricane Katrina disrupted offshore oil and gas
production and shut down eight major refineries in the Gulf Coast region,
sending oil and gasoline prices higher. We continue to monitor these trends
closely.

     For the fiscal year, all 10 sectors of the S&P 500 Index posted gains. Of
the five sectors in which the Fund primarily invests, performance varied
widely--from the energy sector's 52% return to the financials sector's 4%
return. See the table below for more specific information about the performance
of market sectors in which the Fund invests the bulk of its assets.

                              Solid stock selection
                              allowed your Fund to
                            significantly outperform
                            the S&P 500 Index in
                            each of the five sectors
                             in which it invests...

     All 20 of your Fund's energy-sector holdings contributed positively to Fund
performance. Our largest energy holdings were MURPHY OIL and VALERO ENERGY.
Murphy Oil continued to benefit from its contract to supply Wal-Mart's (not a
Fund holding) gas stations. Also, new discoveries in the Congo have the
potential to boost the company's production capacity. Valero is a leading
refiner of grades of oil that are heavier and higher in sulfur. While these
grades cost somewhat more to refine, they cost much less to buy, giving Valero a
cost advantage over its competitors.

     Within the financials sector, life insurer PRUDENTIAL contributed to Fund
performance while FANNIE MAE detracted. Prudential's commitment to returning
excess capital to shareholders has been a major driver of its performance for
the last several years. Fannie Mae, a government-sponsored mortgage company,
continued to be hurt by accounting and regulatory probes; nonetheless we
continued to hold it because we believe it represents a compelling long-term
investment.

AIM MULTI-SECTOR FUND

     Within the health care sector, PACIFICARE contributed to Fund performance
while FOREST LABS detracted. PacifiCare has long been regarded as a well-managed
industry leader, but its stock got an added boost when the company announced in
July that it would merge with UnitedHealth Group (not a Fund holding). Forest
Labs has faced increased generic competition and its product pipeline appears to
us to have faltered. As a result, we reduced our exposure to the company.

                             Of the five sectors in
                            which the Fund primarily
                              invests, performance
                                varied widely...

     Within the information technology sector, APPLE COMPUTER helped while AVID
TECHNOLOGY hindered Fund performance. Apple's stock has performed well for
several years, due in large part to the phenomenal success of the company's iPod
- --REGISTERED TRADEMARK-- device and iTunes music store. Avid Technology's
preeminent position in digital editing platforms and professional digital
newsrooms could not overcome poor execution and a questionable acquisition
strategy. We eliminated Avid Technology from the Fund.

     Within the leisure sector, HARRAH'S ENTERTAINMENT helped while newspaper
publisher TRIBUNE hindered Fund performance. Harrah's seems not to have been
hurt by rising gasoline prices, as many investors had feared, and the company
continued to report good earnings. Tribune was hurt as some if its employment
and real estate advertising moved to the Internet, and the company found itself
under scrutiny regarding its circulation figures. As a result, we eliminated
Tribune from the portfolio.

IN CLOSING
At the close of the fiscal year, economic data painted a generally positive
picture of the U.S. economy, despite rising short-term interest rates and
historically high energy prices. No one was certain how significant the effects
of Hurricane Katrina would be for the nation's economy or for individual sectors
or companies. That is why we continue to maintain a long-term investment
horizon, and why we encourage shareholders to do the same. As always, we thank
you for your continued investment in AIM Multi-Sector Fund.

The data shown in the chart include reinvested distributions, applicable sales
charges, Fund expenses and management fees. Results for Class B shares are
calculated as if a hypo-thetical shareholder had liquidated his entire
investment in the Fund at the close of the reporting period and paid the
applicable contingent deferred sales charges. Index results include reinvested
dividends, but they do not reflect sales charges. Performance of an index of
funds reflects fund expenses and management fees; performance of a market index
does not. Performance shown in the chart and table(s) does not reflect deduction
of taxes a shareholder would pay on Fund distributions or sale of Fund shares.
Performance of the indexes does not reflect the effects of taxes.

SALES CHARGE STRUCTURES AND CLASS EXPENSES.

     HAD THE ADVISOR NOT WAIVED FEES AND/OR REIMBURSED EXPENSES IN THE PAST,
PERFORMANCE WOULD HAVE BEEN LOWER.

AIM MULTI-SECTOR FUND

CALCULATING YOUR ONGOING FUND EXPENSES

EXAMPLE
As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, which may include sales charges (loads) on purchase payments; contingent
deferred sales charges on redemptions; and redemption fees, if any; and (2)
ongoing costs, including management fees; distribution and/or service fees
(12b-1); and other Fund expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with ongoing costs of investing in other mutual funds. The
example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period March 1, 2005, through August 31, 2005.

ACTUAL EXPENSES
The table below provides information about actual account values and actual
expenses. You may use the information in this table, together with the amount
you invested, to estimate the expenses that you paid over the period. Simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Actual Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The table below also provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The Fund's actual cumulative total returns at net asset value after
expenses for the six months ended August 31, 2005, appear in the table "Fund vs.
Indexes" on Page 3.

     The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period. You may
use this information to compare the ongoing costs of investing in the Fund and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

     Please note that the expenses shown in the table are meant to highlight
your ongoing costs only and do not reflect any transactional costs, such as
sales charges (loads) on purchase payments, contingent deferred sales charges on
redemptions, and redemption fees, if any. Therefore, the hypothetical
information is useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

/1/The actual ending account value is based on the actual total return of the
Fund for the period March 1, 2005, through August 31, 2005, after actual
expenses and will differ from the hypothetical ending account value which is
based on the Fund's expense ratio and a hypothetical annual return of 5% before
expenses. The Fund's actual cumulative total returns at net asset value after
expenses for the six months ended August 31, 2005, appear in the table "Fund vs.
Indexes" on Page 3.

/2/Expenses are equal to the Fund's annualized expense ratio (1.47%, 2.16% and
2.16% for Class A, B and C shares, respectively) multiplied by the average
account value over the period, multiplied by 184/365 (to reflect the one-half
year period). Effective on July 1, 2005, the distributor contractually agreed to
reduce rule 12b-1 plan fees for Class A shares to 0.25%. The annualized expense
ratio restated as if this agreement had been in effect throughout the entire
most recent fiscal half year is 1.41% for the Class A shares.

/3/The actual expenses paid restated as if the changes discussed above had been
in effect throughout the entire most recent fiscal half year are $7.41 for the
Class A shares.

/4/The hypothetical expenses paid restated as if the changes discussed above had
been in effect throughout the entire most recent fiscal half year are $7.17 for
the Class A shares.

AIM MULTI-SECTOR FUND

APPROVAL OF INVESTMENT ADVISORY AGREEMENT AND SUMMARY OF INDEPENDENT WRITTEN FEE
EVALUATION

The Board of Trustees of AIM Counselor Series Trust (the "Board") oversees the
management of AIM Multi-Sector Fund (the "Fund") and, as required by law,
determines annually whether to approve the continuance of the Fund's advisory
agreement with A I M Advisors, Inc. ("AIM"). Based upon the recommendation of
the Investments Committee of the Board, which is comprised solely of independent
trustees, at a meeting held on June 30,2005, the Board, including all of the
independent trustees, approved the continuance of the advisory agreement (the
"Advisory Agreement") between the Fund and AIM for another year, effective July
1,2005.

     The Board considered the factors discussed below in evaluating the fairness
and reasonableness of the Advisory Agreement at the meeting on June 30, 2005 and
as part of the Board's ongoing oversight of the Fund. In their deliberations,
the Board and the independent trustees did not identify any particular factor
that was controlling, and each trustee attributed different weights to the
various factors.

     One of the responsibilities of the Senior Officer of the Fund, who is
independent of AIM and AIM's affiliates, is to manage the process by which the
Fund's proposed management fees are negotiated to ensure that they are
negotiated in a manner which is at arm's length and reasonable. To that end, the
Senior Officer must either supervise a competitive bidding process or prepare an
independent written evaluation. The Senior Officer has recommended an
independent written evaluation in lieu of a competitive bidding process and,
upon the direction of the Board, has prepared such an independent written
evaluation. Such written evaluation also considered certain of the factors
discussed below. In addition, as discussed below, the Senior Officer made
certain recommendations to the Board in connection with such written evaluation.

     The discussion below serves as a summary of the Senior Officer's
independent written evaluation and recommendations to the Board in connection
therewith, as well as a discussion of the material factors and the conclusions
with respect thereto that formed the basis for the Board's approval of the
Advisory Agreement. After consideration of all of the factors below and based on
its informed business judgment, the Board determined that the Advisory Agreement
is in the best interests of the Fund and its shareholders and that the
compensation to AIM under the Advisory Agreement is fair and reasonable and
would have been obtained through arm's length negotiations.

.. The nature and extent of the advisory services to be provided by AIM. The
Board reviewed the services to be provided by AIM under the Advisory Agreement.
Based on such review, the Board concluded that the range of services to be
provided by AIM under the Advisory Agreement was appropriate and that AIM
currently is providing services in accordance with the terms of the Advisory
Agreement.

.. The quality of services to be provided by AIM. The Board reviewed the
credentials and experience of the officers and employees of AIM who will provide
investment advisory services to the Fund. In reviewing the qualifications of AIM
to provide investment advisory services, the Board reviewed the qualifications
of AIM's investment personnel and considered such issues as AIM's portfolio and
product review process, various back office support functions provided by AIM
and AIM's equity and fixed income trading operations. Based on the review of
these and other factors, the Board concluded that the quality of services to be
provided by AIM was appropriate and that AIM currently is providing satisfactory
services in accordance with the terms of the Advisory Agreement.

.. The performance of the Fund relative to comparable funds. The Board reviewed
the performance of the Fund during the past one and two calendar years against
the performance of funds advised by other advisors with investment strategies
comparable to those of the Fund. The Board noted that the Fund's performance in
such periods was above the median performance of such comparable funds. The
Board also noted that AIM began serving as investment advisor to the Fund in
November 2003. Based on this review, the Board concluded that no changes should
be made to the Fund and that it was not necessary to change the Fund's portfolio
management team at this time.

.. The performance of the Fund relative to indices. The Board reviewed the
performance of the Fund during the past one and two calendar years against the
performance of the Lipper Multi-Cap Core Index. The Board noted that the Fund's
performance for the two year period was comparable to the performance of such
Index and was above the Index performance for the one year period. The Board
also noted that AIM began serving as investment advisor to the Fund in November
2003. Based on this review, the Board concluded that no changes should be made
to the Fund and that it was not necessary to change the Fund's portfolio
management team at this time.

.. Meeting with the Fund's portfolio managers and investment personnel. With
respect to the Fund, the Board is meeting periodically with such Fund's
portfolio managers and/or other investment personnel and believes that such
individuals are competent and able to continue to carry out their
responsibilities under the Advisory Agreement.

.. Overall performance of AIM. The Board considered the overall performance of
AIM in providing investment advisory and portfolio administrative services to
the Fund and concluded that such performance was satisfactory.

.. Fees relative to those of clients of AIM with comparable investment
strategies. The Board noted that AIM does not serve as an advisor to other
mutual funds or other clients with investment strategies comparable to those of
the Fund.

.. Fees relative to those of comparable funds with other advisors. The Board
reviewed the advisory fee rate for the Fund under the Advisory Agreement. The
Board compared effective contractual advisory fee rates at a common asset level
and noted that the Fund's rate was below the median rate of the funds advised by
other advisors with investment strategies comparable to those of the Fund that
the Board reviewed. The Board noted that AIM has agreed to waive advisory fees
of the Fund and to limit the Fund's total operating expenses, as discussed
below. Based on this review, the Board concluded that the advisory fee rate for
the Fund under the Advisory Agreement was fair and reasonable.

.. Expense limitations and fee waivers. The Board noted that AIM has
contractually agreed to waive advisory fees of the Fund through December 31,
2009 to the extent necessary so that the advisory fees payable by the Fund do
not exceed a specified maximum advisory fee rate, which maximum rate includes
breakpoints and is based on net asset levels. The Board considered the
contractual nature of this fee waiver and noted that it remains in effect until
December 31, 2009. The Board noted that AIM has contractually agreed to waive
fees and/or limit expenses of the Fund through August 31, 2005 in an amount
necessary to limit total annual operating expenses to a specified percentage of
average daily net assets for each class of the Fund. The Board considered the
contractual nature of this fee waiver/expense limitation and noted that it
remains in effect until August 31, 2005. The Board considered the effect these
fee waivers/expense limitations would have on the Fund's estimated expenses and
concluded that the levels of fee waivers/expense limitations for the Fund were
fair and reasonable.

.. Breakpoints and economies of scale. The Board reviewed the structure of the
Fund's advisory fee under the Advisory Agreement, noting that it does not
include any breakpoints. The Board considered whether it would be appropriate to
add advisory fee breakpoints for the Fund or whether, due to the nature of the
Fund and the advisory fee structures of comparable funds, it was reasonable to
structure the advisory fee without breakpoints. Based on this review, the Board
concluded that it was not necessary to add advisory fee breakpoints to the
Fund's advisory fee schedule. The Board reviewed the level of the Fund's
advisory fees, and noted that such fees, as a percentage of the Fund's net
assets, would remain constant under the Advisory Agreement because the Advisory
Agreement does not include any breakpoints. The Board noted that AIM has
contractually agreed to waive advisory fees of the Fund through December 31,
2009 to the extent necessary so that the advisory fees payable by the Fund do
not exceed a specified maximum advisory fee rate, which maximum rate includes
breakpoints and is based on net asset levels. The Board concluded that the
Fund's fee levels under the Advisory Agreement therefore would not reflect
economies of scale, although the advisory fee waiver reflects economies of
scale.

                                                          (Continued on Page 10)

AIM MULTI-SECTOR FUND

.. Investments in affiliated money market funds. The Board also took into account
the fact that uninvested cash and cash collateral from securities lending
arrangements (collectively, "cash balances") of the Fund may be invested in
money market funds advised by AIM pursuant to the terms of an SEC exemptive
order. The Board found that the Fund may realize certain benefits upon investing
cash balances in AIM advised money market funds, including a higher net return,
increased liquidity, increased diversification or decreased transaction costs.
The Board also found that the Fund will not receive reduced services if it
invests its cash balances in such money market funds. The Board noted that, to
the extent the Fund invests in affiliated money market funds, AIM has
voluntarily agreed to waive a portion of the advisory fees it receives from the
Fund attributable to such investment. The Board further determined that the
proposed securities lending program and related procedures with respect to the
lending Fund is in the best interests of the lending Fund and its respective
shareholders. The Board therefore concluded that the investment of cash
collateral received in connection with the securities lending program in the
money market funds according to the procedures is in the best interests of the
lending Fund and its respective shareholders.

.. Independent written evaluation and recommendations of the Fund's Senior
Officer. The Board noted that, upon their direction, the Senior Officer of the
Fund, who is independent of AIM and AIM's affiliates, had prepared an
independent written evaluation in order to assist the Board in determining the
reasonableness of the proposed management fees of the AIM Funds, including the
Fund. The Board noted that the Senior Officer's written evaluation had been
relied upon by the Board in this regard in lieu of a competitive bidding
process. In determining whether to continue the Advisory Agreement for the Fund,
the Board considered the Senior Officer's written evaluation and the
recommendation made by the Senior Officer to the Board that the Board consider
implementing a process to assist them in more closely monitoring the performance
of the AIM Funds. The Board concluded that it would be advisable to implement
such a process as soon as reasonably practicable.

.. Profitability of AIM and its affiliates. The Board reviewed information
concerning the profitability of AIM's (and its affiliates') investment advisory
and other activities and its financial condition. The Board considered the
overall profitability of AIM, as well as the profitability of AIM in connection
with managing the Fund. The Board noted that AIM's operations remain profitable,
although increased expenses in recent years have reduced AIM's profitability.
Based on the review of the profitability of AIM's and its affiliates' investment
advisory and other activities and its financial condition, the Board concluded
that the compensation to be paid by the Fund to AIM under its Advisory Agreement
was not excessive.

.. Benefits of soft dollars to AIM. The Board considered the benefits realized by
AIM as a result of brokerage transactions executed through "soft dollar"
arrangements. Under these arrangements, brokerage commissions paid by the Fund
and/or other funds advised by AIM are used to pay for research and execution
services. This research is used by AIM in making investment decisions for the
Fund. The Board concluded that such arrangements were appropriate.

.. AIM's financial soundness in light of the Fund's needs. The Board considered
whether AIM is financially sound and has the resources necessary to perform its
obligations under the Advisory Agreement, and concluded that AIM has the
financial resources necessary to fulfill its obligations under the Advisory
Agreement.

.. Historical relationship between the Fund and AIM. In determining whether to
continue the Advisory Agreement for the Fund, the Board also considered the
prior relationship between AIM and the Fund, as well as the Board's knowledge of
AIM's operations, and concluded that it was beneficial to maintain the current
relationship, in part, because of such knowledge. The Board also reviewed the
general nature of the non-investment advisory services currently performed by
AIM and its affiliates, such as administrative, transfer agency and distribution
services, and the fees received by AlM and its affiliates for performing such
services. In addition to reviewing such services, the trustees also considered
the organizational structure employed by AIM and its affiliates to provide those
services. Based on the review of these and other factors, the Board concluded
that AIM and its affiliates were qualified to continue to provide non-investment
advisory services to the Fund, including administrative, transfer agency and
distribution services, and that AIM and its affiliates currently are providing
satisfactory non-investment advisory services.

.. Other factors and current trends. In determining whether to continue the
Advisory Agreement for the Fund, the Board considered the fact that AIM, along
with others in the mutual fund industry, is subject to regulatory inquiries and
litigation related to a wide range of issues. The Board also considered the
governance and compliance reforms being undertaken by AIM and its affiliates,
including maintaining an internal controls committee and retaining an
independent compliance consultant, and the fact that AIM has undertaken to cause
the Fund to operate in accordance with certain governance policies and
practices. The Board concluded that these actions indicated a good faith effort
on the part of AIM to adhere to the highest ethical standards, and determined
that the current regulatory and litigation environment to which AIM is subject
should not prevent the Board from continuing the Advisory Agreement for the
Fund.

INFORMATION ABOUT YOUR FUND'S EXPENSES

CALCULATING YOUR ONGOING FUND EXPENSES

EXAMPLE
As a shareholder of the Fund, you incur ongoing costs, including management fees
and other Fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with ongoing costs of investing in other mutual funds. The example is based on
an investment of $1,000 invested at the beginning of the period and held for the
entire period March 1, 2005, through August 31, 2005.

ACTUAL EXPENSES
The table below provides information about actual account values and actual
expenses. You may use the information in this table, together with the amount
you invested, to estimate the expenses that you paid over the period. Simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the table
under the heading entitled "Actual Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The table below also provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The Fund's actual cumulative total return after expenses for the six
months ended August 31, 2005, appears in the table on the front of this
supplement.

     The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period. You may
use this information to compare the ongoing costs of investing in the Fund and
other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

     Please note that the expenses shown in the table are meant to highlight
your ongoing costs only. Therefore, the hypothetical information is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds.

/1/The actual ending account value is based on the actual total return of the
Fund for the period March 1, 2005, through August 31, 2005, after actual
expenses and will differ from the hypothetical ending account value which is
based on the Fund's expense ratio and a hypothetical annual return of 5% before

NOTES TO FINANCIAL STATEMENTS
August 31, 2005

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

AIM Multi-Sector Fund, formerly INVESCO Multi-Sector Fund, (the "Fund") is a
series portfolio of AIM Counselor Series Trust (the "Trust"). The Trust is a
Delaware statutory trust registered under the Investment Company Act of 1940,
as amended (the "1940 Act"), as an open-end series management investment
company consisting of two separate portfolios, each authorized to issue an
unlimited number of shares of beneficial interest. The Fund currently offers
multiple classes of shares. 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 seek capital growth.
  Under the Trust's organizational documents, each Trustee, officer, employee
or other agent of the Trust (including the Trust's investment manager) is
indemnified against certain liabilities that may arise out of performance of
their duties to the Fund. Additionally, in the normal course of business, the
Fund enters into contracts that contain a variety of indemnification clauses.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. However, the Fund has not had prior claims or losses pursuant to
these contracts.
  The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 including
estimates and assumptions related to taxation. 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 -- Securities, including restricted securities, are
   valued according to the following policy. 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
   traded in the over-the-counter market (but not securities reported on the
   NASDAQ National Market System) is valued on the basis of prices furnished by
   independent pricing services, which may be considered fair valued, or market
   makers. Each security reported on the NASDAQ National Market System is
   valued at the NASDAQ Official Closing Price ("NOCP") as of the close of the
   customary trading session on the valuation date or absent a NOCP, at the
   closing bid price.
     Futures contracts are valued at the final settlement price set by an
   exchange on which they are principally traded. Listed options are valued at
   the mean between the last bid and the ask prices from the exchange on which
   they are principally traded. Options not listed on an exchange are valued by
   an independent source at the mean between the last bid and ask prices. 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").
     Investments in open-end registered investment companies and closed-end
   registered investment companies that do not trade on an exchange are valued
   at the end of day net asset value per share. Investments in closed-end
   registered investment companies that trade on an exchange are valued at the
   last sales price as of the close of the customary trading session on the
   exchange where the security is principally traded.
     Debt obligations (including convertible bonds) are fair valued using an
   evaluated quote provided by an independent pricing service. Evaluated quotes
   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 specific securities, dividend rate, yield, quality, type of
   issue, coupon rate, maturity, individual trading characteristics and other
   market data. Short-term obligations having 60 days or less to maturity and
   commercial paper are valued at amortized cost which approximates market
   value.
     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.
     Foreign securities (including foreign exchange contracts) are converted
   into U.S. dollar amounts using the applicable exchange rates as of the close
   of the 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 the close of the respective markets.
   Events affecting the values of such foreign securities may occur between the
   times at which the particular foreign market closes and the close of the
   customary trading session of the NYSE which would not ordinarily be
   reflected in the computation of the Fund's net asset value. If the event is
   likely to have affected the closing price of the security, the security will
   be valued at fair value in good faith using procedures approved by the Board
   of Trustees. Adjustments to closing prices to reflect fair value may also be
   based on a screening process of an independent pricing service to indicate
   the degree of certainty, based on historical data, that the closing price in
   the principal market where a foreign security trades is not the current
   market value as of the close of the NYSE. Foreign securities meeting the
   approved degree of certainty that the price is not reflective of current
   market value will be priced at the indication of fair value from the
   independent pricing service. Multiple factors may be considered by the
   independent pricing service in determining adjustments to reflect fair value
   and may include information relating to sector indices, ADRs and domestic
   and foreign index futures.
     Securities for which market quotations are not readily available or are
   unreliable are valued at fair value as determined in good faith by or under
   the supervision of the Trust's officers following procedures approved by the
   Board of Trustees. Issuer specific events, market trends, bid/ask quotes of
   brokers and information providers and other market data may be reviewed in
   the course of making a good faith determination of a security's fair value.
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 on the accrual basis from settlement date.
   Dividend income is recorded on the ex-dividend date.

                                      F-7




     Brokerage commissions and mark ups are considered transaction costs and
   are recorded as an increase to the cost basis of securities purchased and/or
   a reduction of proceeds on a sale of securities. Such transaction costs are
   included in the determination of realized and unrealized gain (loss) from
   investment securities reported in the Statement of Operations and the
   Statement of Changes in Net Assets and the realized and unrealized net gains
   (losses) on securities per share in the Financial Highlights. Transaction
   costs are included in the calculation of the Fund's net asset value and,
   accordingly, they reduce the Fund's total returns. These transaction costs
   are not considered operating expenses and are not reflected in net
   investment income reported in the Statement of Operations and Statement of
   Changes in Net Assets, or the net investment income per share and ratios of
   expenses and net investment income reported in the Financial Highlights, nor
   are they limited by any expense limitation arrangements between the Fund and
   the advisor.
     The Fund allocates income and realized and unrealized capital gains and
   losses to a class based on the relative net assets of each class.
C. COUNTRY DETERMINATION -- For the purposes of making investment selection
   decisions and presentation in the Schedule of Investments, AIM may determine
   the country in which an issuer is located and/or credit risk exposure based
   on various factors. These factors include the laws of the country under
   which the issuer is organized, where the issuer maintains a principal
   office, the country in which the issuer derives 50% or more of its total
   revenues and the country that has the primary market for the issuer's
   securities, as well as other criteria. Among the other criteria that may be
   evaluated for making this determination are the country in which the issuer
   maintains 50% or more of its assets, the type of security, financial
   guarantees and enhancements, the nature of the collateral and the sponsor
   organization. Country of issuer and/or credit risk exposure has been
   determined to be United States of America unless otherwise noted.
D. DISTRIBUTIONS -- Distributions from income and net realized capital gain, 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.
E. FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of
   Subchapter M 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
   gain) which is distributed to shareholders. Therefore, no provision for
   federal income taxes is recorded in the financial statements.
F. EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular
   class of the Fund are charged to the operations of such class. Transfer
   agency fees and expenses and other shareholder recordkeeping fees and
   expenses attributable to the Institutional Class are charged to such class.
   Transfer agency fees and expenses and other shareholder recordkeeping fees
   and expenses relating to all other classes are allocated among those classes
   based on relative net assets. All other expenses are allocated among the
   classes based on relative net assets.
G. FOREIGN CURRENCY TRANSLATIONS -- Foreign currency is valued at the close of
   the NYSE based on quotations posted by banks and major currency dealers.
   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 (net of foreign taxes withheld
   on disposition) 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 the 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. The combined results of changes in foreign exchange rates
   and the fluctuation of market prices on investments (net of estimated
   foreign tax withholding) are included with the net realized and unrealized
   gain or loss from investments in the Statement of Operations. Reported net
   realized foreign currency gains or losses arise from (i) sales of foreign
   currencies, (ii) currency gains or losses realized between the trade and
   settlement dates on securities transactions, and (iii) the difference
   between the amounts of dividends, interest, and foreign withholding taxes
   recorded on the Fund's books and the U.S. dollar equivalent of the amounts
   actually received or paid. Net unrealized foreign currency gains and losses
   arise from changes in the fair values of assets and liabilities, other than
   investments in securities at fiscal period end, resulting from changes in
   exchange rates.
H. 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.
I. COVERED CALL OPTIONS -- The Fund may write call options, on a covered basis;
   that is, the Fund will own the underlying security. 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 risk in writing a call
   option is that the Fund gives up the opportunity for profit if the market
   price of the security increases and the option is exercised.
J. 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. A risk in
   buying an option is that the Fund pays a premium whether or not the option
   is exercised. In addition, there can be no assurance that a liquid secondary
   market will exist for any option purchased or sold.
K. COLLATERAL -- To the extent the Fund has pledged or segregated a security as
   collateral and that security is subsequently sold, it is the Fund's practice
   to replace such collateral no later than the next business day.

                                      F-8





NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES

The Trust has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the investment advisory agreement,
the Fund pays an advisory fee at the annual rate of 0.75% of the Fund's average
daily net assets. Through December 31, 2009, AIM has contractually agreed to
waive advisory fees to the extent necessary so that the advisory fees payable
by the Fund (based on the Fund's average daily net assets) do not exceed the
annual rate of:



              AVERAGE NET ASSETS                             RATE
              ----------------------------------------------------

              Next $2.5 billion                             0.57%
              ----------------------------------------------------
              Next $2.5 billion                             0.545%
              ----------------------------------------------------
              Over $10 billion                              0.52%
              ----------------------------------------------------


  Prior to September 30, 2004, under the terms of a master sub-advisory
agreement between AIM and INVESCO Institutional (N.A.), Inc. ("INVESCO"), AIM
paid INVESCO 40% of the fee paid by the Fund to AIM. This sub-advisory
agreement expired on September 30, 2004.
  AIM has contractually agreed to waive advisory fees and/or reimburse expenses
to the extent necessary to limit total annual operating expenses (excluding
certain items discussed below) of Class A, Class B, Class C and Institutional
Class shares to 1.90%, 2.65%, 2.65% and 1.65% of average daily net assets,
respectively, through August 31, 2006. In determining the advisor's obligation
to waive advisory fees and/or reimburse expenses, the following expenses are
not taken into account, and could cause the total annual fund operating
expenses to exceed the limits stated above: (i) interest; (ii) taxes;
(iii) dividend expense on short sales; (iv) extraordinary items (these are
expenses that are not anticipated to arise from the Fund's day-to-day
operations), or items designated as such by the Fund's Board of Trustees;
(v) expenses related to a merger or reorganization, as approved by the Fund's
Board of Trustees; and (vi) expenses that the Fund has incurred but did not
actually pay because of an expense offset arrangement. Currently, in addition
to the expense reimbursement arrangement with AMVESCAP PLC ("AMVESCAP")
described more fully below, the expense offset arrangements from which the Fund
may benefit are in the form of credits that the Fund receives from banks where
the Fund or its transfer agent has deposit accounts in which it holds
uninvested cash. Those credits are used to pay certain expenses incurred by the
Fund.
  Further, AIM has voluntarily agreed to waive advisory fees of the Fund in the
amount of 25% of the advisory fee AIM receives from the affiliated money market
funds on investments by the Fund in such affiliated money market funds. AIM is
also voluntarily waiving a portion of the advisory fee payable by the Fund
equal to the difference between the income earned from investing in the
affiliated money market fund and the hypothetical income earned from investing
in an appropriate comparative benchmark. Voluntary fee waivers or
reimbursements may be modified or discontinued at any time upon consultation
with the Board of Trustees without further notice to investors.
  For the year ended August 31, 2005, AIM waived fees of $51,656.
  At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse
expenses incurred by the Fund in connection with market timing matters in the
AIM Funds, which may include legal, audit, shareholder reporting,
communications and trustee expenses. These expenses along with the related
expense reimbursement, are included in the Statement of Operations. For the
year ended August 31, 2005, AMVESCAP reimbursed expenses of the Fund in the
amount of $19,948.
  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. Pursuant to such agreement, for the year ended
August 31, 2005, AIM was paid $50,000.
  The Fund, pursuant to a transfer agency and service agreement, has agreed to
pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer agency
and shareholder services to the Fund and reimburse AISI for certain expenses
incurred by AISI in the course of providing such services. AISI may make
payments to intermediaries that provide omnibus account services,
sub-accounting services and/or networking services. For the year ended
August 31, 2005, the Fund paid AISI $175,104 for Class A, Class B and Class C
share classes and $3,379 for Institutional Class shares.
  The Trust has entered into master distribution agreements with A I M
Distributors, Inc. ("ADI") to serve as the distributor for the Class A, Class
B, Class C and Institutional Class 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, Class B and Class C shares (collectively the "Plans"). The Fund,
pursuant to the Class A, Class B and Class C Plans, pays ADI 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 Class C shares.
Prior to July 1, 2005, the Fund paid ADI 0.35% of the average daily net assets
of Class A shares. Of these amounts, up to 0.25% of the average daily net
assets of the Class A, Class B or Class C shares may be paid to furnish
continuing personal shareholder services to customers who purchase and own
shares of such classes. Any amounts not paid as a service fee under the Plans
would constitute an asset-based sales charge. National Association of
Securities Dealers ("NASD") Rules impose a cap on the total sales charges,
including asset-based sales charges that may be paid by any class of shares of
the Fund. Pursuant to the Plans, for the year ended August 31, 2005, the
Class A, Class B and Class C shares paid $176,390, $156,282 and $213,976,
respectively.
  Front-end sales commissions and contingent deferred sales charges ("CDSC")
(collectively the "sales charges") are not recorded as expenses of the Fund.
Front-end sales commissions are deducted from proceeds from the sales of Fund
shares prior to investment in Class A shares of the Fund. CDSC are deducted
from redemption proceeds prior to remittance to the shareholder. For the year
ended August 31, 2005, ADI advised the Fund that it retained $52,345 in
front-end sales commissions from the sale of Class A shares and $221, $13,836
and $2,983 from Class A, Class B and Class C shares, respectively, for CDSC
imposed upon redemptions by shareholders.
  Certain officers and trustees of the Trust are officers and directors of AIM,
AISI, INVESCO and/or ADI.

NOTE 3--INVESTMENTS IN AFFILIATES

The Fund is permitted, pursuant to an exemptive order from the Securities and
Exchange Commission ("SEC") and approved procedures by the Board of Trustees,
to invest daily available cash balances in affiliated money market funds. The
Fund and the money market fund below have the same investment advisor and
therefore, are considered to be affiliated. The table below shows the
transactions in and earnings from investments in an affiliated money market
fund for the year ended August 31, 2005.




                                                                               CHANGE IN

NOTE 4--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS

The Fund is permitted to purchase or sell securities from or to certain other
AIM Funds under specified conditions outlined in procedures adopted by the
Board of Trustees of the Trust. The procedures have been designed to ensure
that any purchase or sale of securities by the Fund from or to another fund or
portfolio that is or could be considered an affiliate by virtue of having a
common investment advisor (or affiliated investment advisors), common Trustees
and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as
defined under the procedures, each transaction is effected at the current
market price. Pursuant to these procedures, during the year ended August 31,
2005, the Fund engaged in securities purchases of $1,277,480 and sales of
$505,622, which resulted in net realized gains of $66,634.

NOTE 5--EXPENSE OFFSET ARRANGEMENT

The expense offset arrangement is comprised of transfer agency credits which
result from balances in Demand Deposit Accounts (DDA) used by the transfer
agent for clearing shareholder transactions. For the year ended August 31,
2005, the Fund received credits from this arrangement, which resulted in the
reduction of the Fund's total expenses of $3,029.

NOTE 6--TRUSTEES' AND OFFICER'S FEES AND BENEFITS

"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to each Trustee and Officer of the Fund who is not an
"interested person" of AIM. Trustees have the option to defer compensation
payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also
include amounts accrued by the Fund to fund such deferred compensation amounts.
Those Trustees who defer compensation have the option to select various AIM
Funds in which their deferral accounts shall be deemed to be invested. Finally,
current Trustees are eligible to participate in a retirement plan that provides
for benefits to be paid upon retirement to Trustees over a period of time based
on the number of years of service. The Fund may have certain former Trustees
who also participate in a retirement plan and receive benefits under such plan.
"Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund
to fund such retirement benefits. Obligations under the deferred compensation
and retirement plans represent unsecured claims against the general assets of
the Fund.
  During the year ended August 31, 2005, the Fund paid legal fees of $4,253 for
services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Independent Trustees. A member of that firm is a Trustee of the Trust.

NOTE 7--BORROWINGS

Pursuant to an exemptive order from the SEC, the Fund may participate in an
interfund lending facility that AIM has established for temporary borrowings by
the AIM Funds. An interfund loan will be made under this facility only if the
loan rate (an average of the rate available on bank loans and the rate
available on investments in overnight repurchase agreements) is favorable to
both the lending fund and the borrowing fund. A loan will be secured by
collateral if the Fund's aggregate borrowings from all sources exceeds 10% of
the Fund's total assets. To the extent that the loan is required to be secured
by collateral, the collateral is marked to market daily to ensure that the
market value is at least 102% of the outstanding principal value of the loan.
  The Fund is a participant in an uncommitted unsecured revolving credit
facility with State Street Bank and Trust Company ("SSB"). The Fund may borrow
up to the lesser of (i) $125,000,000, or (ii) the limits set by its prospectus
for borrowings. The Fund and other funds advised by AIM which are parties to
the credit facility can borrow on a first come, first served basis. Principal
on each loan outstanding shall bear interest at the bid rate quoted by SSB at
the time of the request for the loan.
  During the year ended August 31, 2005, the Fund did not borrow or lend under
the interfund lending facility or borrow under the uncommitted unsecured
revolving credit facility.
  Additionally, the Fund is permitted to temporarily carry a negative or
overdrawn balance in its account with SSB, the custodian bank. To compensate
the custodian bank for such overdrafts, the overdrawn Fund may either (i) leave
funds as a compensating balance in the account so the custodian can be
compensated by earning the additional interest; or (ii) compensate by paying
the custodian bank at a rate agreed upon by the custodian bank and AIM, not to
exceed the rate contractually agreed upon.

TAX COMPONENTS OF NET ASSETS:

As of August 31, 2005, the components of net assets on a tax basis were as
follows:



                                                        2005
              ---------------------------------------------------
                                                 
              Undistributed ordinary income         $  3,923,654
              ---------------------------------------------------
              Undistributed long-term gain               970,780
              ---------------------------------------------------
              Unrealized appreciation - investments   27,628,491
              ---------------------------------------------------
              Temporary book/tax differences              (5,787)
              ---------------------------------------------------
              Post-October currency loss deferral        (48,444)
              ---------------------------------------------------
              Shares of beneficial interest          167,814,042
              ---------------------------------------------------
              Total net assets                      $200,282,736
              ---------------------------------------------------

  The difference between book-basis and tax-basis unrealized appreciation
(depreciation) is due to differences in the timing of recognition of gains and
losses on investments for tax and book purposes. The Fund's unrealized
appreciation (depreciation) difference is attributable primarily to the
deferral of losses on wash sales, the recognition for tax purposes of
unrealized gains on passive foreign investment companies and the deferral of
losses on certain straddle transactions. The tax-basis unrealized appreciation
(depreciation) on investments amount includes appreciation on foreign
currencies of $588.
  The temporary book/tax differences are a result of timing differences between
book and tax recognition of income and/or expenses. The Fund's temporary
book/tax differences are the result of the trustee deferral of compensation and
retirement plan expenses.
  The Fund had no capital loss carryforward as of August 31, 2005.

NOTE 10--INVESTMENT SECURITIES

The aggregate amount of investment securities (other than short-term securities
and money market funds) purchased and sold by the Fund during the year ended
August 31, 2005 was $161,873,163 and $70,830,269, respectively.



   UNREALIZED APPRECIATION (DEPRECIATION) OF INVESTMENT SECURITIES ON A TAX BASIS
   ------------------------------------------------------------------------------
                                                                
   Aggregate unrealized appreciation of investment securities      $30,159,437
   ------------------------------------------------------------------------------
   Aggregate unrealized (depreciation) of investment securities     (2,531,534)
   ------------------------------------------------------------------------------
   Net unrealized appreciation of investment securities            $27,627,903
   ------------------------------------------------------------------------------

                                     F-11





NOTE 11--RECLASSIFICATION OF PERMANENT DIFFERENCES

Primarily as a result of differing book/tax treatment of foreign currency
transactions, passive foreign investment company transactions, and net
operating losses, on August 31, 2005, undistributed net investment income
(loss) was increased by $9,826, undistributed net realized gain (loss) was
decreased by $289,824 and shares of beneficial interest increased by $279,998.
This reclassification had no effect on the net assets of the Fund.

NOTE 12--SHARE INFORMATION

The Fund currently offers four different classes of shares: Class A shares,
Class B shares, Class C shares and Institutional Class shares. Class A shares
are sold with a front-end sales charge. Class B shares and Class C shares are
sold with CDSC. Institutional Class shares are sold at net asset value. Under
certain circumstances, Class A shares are subject to CDSC. Generally, Class B
shares will automatically convert to Class A shares eight years after the end
of the calendar month of purchase.

NOTE 14--LEGAL PROCEEDINGS

Terms used in the Legal Proceedings Note are defined terms solely for the
purpose of this note.

SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment
advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the
distributor of the retail AIM Funds) reached final settlements with certain
regulators, including the Securities and Exchange Commission ("SEC"), the New
York Attorney General and the Colorado Attorney General, to resolve civil
enforcement actions and/or investigations related to market timing and related
activity in the AIM Funds, including those formerly advised by IFG. As part of
the settlements, a $325 million fair fund ($110 million of which is civil
penalties) has been created to compensate shareholders harmed by market timing
and related activity in funds formerly advised by IFG. Half of this amount has
already been paid to the fair fund pursuant to the terms of the settlement with
the remainder due December 31, 2005. Additionally, AIM and ADI created a $50
million fair fund ($30 million of which is civil penalties) to compensate
shareholders harmed by market timing and related activity in funds advised by
AIM, which was done pursuant to the terms of the settlement. These two fair
funds may increase as a result of contributions from third parties who reach
final settlements with the SEC or other regulators to resolve allegations of
market timing and/or late trading that also may have harmed applicable AIM
Funds. These two fair funds will be distributed in accordance with a
methodology to be determined by AIM's independent distribution consultant, in
consultation with AIM and the independent trustees of the AIM Funds and
acceptable to the staff of the SEC. As the methodology is unknown at the
present time, management of AIM and the Fund are unable to estimate the impact,
if any, that the distribution of these two fair funds may have on the Fund or
whether such distribution will have an impact on the Fund's financial
statements in the future.
  At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"),
the parent company of IFG and AIM, has agreed to reimburse expenses incurred by
the AIM Funds related to market timing matters.

REGULATORY INQUIRIES AND PENDING LITIGATION

  IFG, AIM, ADI and/or related entities and individuals have received inquiries
from numerous regulators in the form of subpoenas or other oral or written
requests for information and/or documents related to one or more of the
following issues, some of which concern one or more AIM Funds: market timing
activity, late trading, fair value pricing, excessive or improper advisory
and/or distribution fees, mutual fund sales practices, including revenue
sharing and directed-brokerage arrangements, investments in securities of other
registered investment companies, contractual plans, issues related to
Section 529 college savings plans and procedures for locating lost
securityholders. IFG, AIM and ADI are providing full cooperation with respect
to these inquiries. As described more fully below, the AIM Funds, IFG, AIM, ADI
and/or related entities and individuals are defendants in numerous civil
lawsuits related to one or more of these issues. Regulatory actions and/or
additional civil lawsuits related to these or other issues may be filed against
the AIM Funds, IFG, AIM and/or related entities and individuals in the future.
  On April 12, 2005, the Attorney General of the State of West Virginia
("WVAG") filed a civil lawsuit against AIM, IFG and ADI, as well as numerous
unrelated mutual fund complexes and financial institutions. None of the AIM
Funds has been named as a defendant in this lawsuit. The WVAG complaint, filed
in the Circuit Court of Marshall County, West Virginia [Civil Action
No. 05-C-81], alleges, in substance, that AIM, IFG and ADI engaged in unfair
competition and/or unfair or deceptive trade practices by failing to disclose
in the prospectuses for the AIM Funds, including those formerly advised by IFG,
that they had entered into certain arrangements permitting market timing of
such Funds. As a result of the foregoing, the WVAG alleges violations of W. Va.
Code (S) 46A-1-101, et seq. (the West Virginia Consumer Credit and Protection
Act). The WVAG complaint is seeking, among other things, injunctive relief,
civil monetary penalties and a writ of quo warranto against the defendants. If
AIM is unsuccessful in its defense of the WVAG lawsuit, it could be barred from
serving as an investment advisor for any investment company registered under
the Investment Company Act of 1940, as amended (a "registered investment
company"). Such results could affect the ability of AIM or any other investment
advisor directly or indirectly owned by AMVESCAP, from serving as an investment
advisor to any registered investment company, including the Fund. The Fund has
been informed by AIM that, if these results occur, AIM will seek exemptive
relief from the SEC to permit it to continue to serve as the Fund's investment
advisor. There is no assurance that such exemptive relief will be granted. On
July 7, 2005, the Supreme Court of West Virginia ruled in the context of a
separate lawsuit that the WVAG does not have authority pursuant to W. Va. Code
Section 46A-6-104 of the West Virginia Consumer Credit and Protection Act to
bring an action based upon conduct that is ancillary to the purchase or sale of
securities. AIM intends to seek dismissal of the WVAG's lawsuit against it, IFG
and ADI in light of this ruling.
  On August 30, 2005, the West Virginia Office of the State Auditor--Securities
Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of
Right to Hearing to AIM and ADI. The WVASC makes findings of fact that
essentially mirror the WVAG's allegations mentioned above and conclusions of
law to the effect that AIM and ADI violated the West Virginia securities laws.
The WVASC orders AIM and ADI to cease any further violations and seeks to
impose monetary sanctions to be determined by the Commissioner. AIM and ADI
have the right to contest the WVASC's findings and conclusions, which they
intend to do.
  Civil lawsuits, including purported class action and shareholder derivative
suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or
related entities and individuals, depending on the lawsuit, alleging:
     .   that the defendants permitted improper market timing and related
         activity in the AIM Funds;
     .   that certain AIM Funds inadequately employed fair value pricing;
     .   that the defendants charged excessive advisory and/or distribution
         fees and failed to pass on to shareholders the perceived savings
         generated by economies of scale and that the defendants adopted
         unlawful distribution plans;
     .   that the defendants breached their fiduciary duties by charging
         distribution fees while AIM Funds and/or specific share classes were
         closed generally to new investors and/or while other share classes of
         the same AIM Fund were not charged the same distribution fees;
     .   that the defendants improperly used the assets of the AIM Funds to pay
         brokers to aggressively promote the sale of the AIM Funds over other
         mutual funds and that the defendants concealed such payments from
         investors by disguising them as brokerage commissions; and
     .   that the defendants breached their fiduciary duties by failing to
         ensure that the AIM Funds participated in class action settlements in
         which they were eligible to participate (this lawsuit was dismissed by
         the Court on August 12, 2005).

                                     F-15




NOTE 14--LEGAL PROCEEDINGS-CONTINUED

These lawsuits allege as theories of recovery, depending on the lawsuit,
violations of various provisions of the Federal and state securities laws and
ERISA, negligence, breach of fiduciary duty and/or breach of contract. These
lawsuits seek remedies that include, depending on the lawsuit, damages,
restitution, injunctive relief, imposition of a constructive trust, removal of
certain directors and/or employees, various corrective measures under ERISA,
rescission of certain AIM Funds' advisory agreements and/or distribution plans
and recovery of all fees paid, an accounting of all fund-related fees,
commissions and soft dollar payments, restitution of all commissions and fees
paid, and prospective relief in the form of reduced fees.
  All lawsuits based on allegations of market timing, late trading and related
activity have been transferred to the United States District Court for the
District of Maryland. On August 25, 2005, the Court issued rulings on the
common issues of law presented in defendants' motions to dismiss the
shareholder class and derivative complaints. These rulings were issued in the
context of the Janus lawsuits, but the Court's legal determinations apply at
the omnibus level to all cases within his track, including the AIM and IFG
cases. The Court dismissed for failure to make pre-suit demand on the fund
board all derivative causes of action but one: the excessive fee claim under
Section 36(b) of the Investment Company Act of 1940 (the "1940 Act"), as to
which the demand requirement does not apply. The Court dismissed all claims
asserted in the class complaint but two: (i) the securities fraud claims under
Section 10(b) of the Securities Exchange Act of 1934, and (ii) the excessive
fee claim under Section 36(b) of the 1940 Act. In addition, the Court limited
plaintiffs' potential recovery on the 36(b) claim to fees attributable to
timing assets, as opposed to all fees on funds in which any timing occurred.
The question whether the duplicative Section 36(b) claim properly belongs in
the derivative complaint or in the class action complaint will be decided at a
later date. The Court will subsequently issue an order applying his legal
rulings to the allegations in the AIM and IFG complaints.
  At the present time, management of AIM and the Fund are unable to estimate
the impact, if any, that the outcome of the Regulatory Inquiries and Pending
Litigation described above may have on AIM, ADI or the Fund.

*    *    *    *    *    *    *    *    *    *    *    *    *    *    *    *

As a result of the matters discussed above, investors in the AIM Funds might
react by redeeming their investments. This might require the AIM Funds to sell
investments to provide for sufficient liquidity and could also have an adverse
effect on the investment performance of the AIM Funds.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees
and Shareholders of AIM Multi-Sector Fund:

In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of AIM Multi-Sector Fund, formerly
known as INVESCO Multi-Sector Fund, (one of the funds constituting AIM
Counselor Series Trust, hereafter referred to as the "Fund") at August 31,
2005, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended and the financial
highlights for each of the periods indicated, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at August 31, 2005 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

- ----------

(1)  With respect to the provision of non-audit services, the pre-approval
     requirement is waived pursuant to a de minimis exception if (i) such
     services were not recognized as non-audit services by the Registrant at the
     time of engagement, (ii) the aggregate amount of all such services provided
     is no more than 5% of the aggregate audit and non-audit fees paid by the
     Registrant, AIM and AIM Affiliates to PWC during a fiscal year; and (iii)
     such services are promptly approved by the Registrant's Audit Committee
     prior to the completion of the audit by the Audit Committee.

(2)  Including the fees for services not required to be pre-approved by the
     registrant's audit committee, PWC billed AIM and AIM Affiliates aggregate
     non-audit fees of $0 for the fiscal year ended 2005, and $0 for the fiscal
     year ended 2004, for non-audit services rendered to AIM and AIM Affiliates.

     The Audit Committee also has considered whether the provision of non-audit
     services that were rendered to AIM and AIM Affiliates that were not
     required to be pre-approved pursuant to SEC regulations, if any, is
     compatible with maintaining PWC's independence.

                  PRE-APPROVAL OF AUDIT AND NON-AUDIT SERVICES
                             POLICIES AND PROCEDURES
                      As adopted by the Audit Committees of
                           the AIM Funds (the "Funds")
                         Last Amended September 13, 2005

I. Statement of Principles

Under the Sarbanes-Oxley Act of 2002 and rules adopted by the Securities and
Exchange Commission ("SEC") ("Rules"), the Audit Committees of the Funds' (the
"Audit Committee") Board of Directors/Trustees (the "Board") are responsible for
the appointment, compensation and oversight of the work of independent
accountants (an "Auditor"). As part of this responsibility and to assure that
the Auditor's independence is not impaired, the Audit Committees pre-approve the
audit and non-audit services provided to the Funds by each Auditor, as well as
all non-audit services provided by the Auditor to the Funds' investment adviser
and to affiliates of the adviser that provide ongoing services to the Funds
("Service Affiliates") if the services directly impact the Funds' operations or
financial reporting. The SEC Rules also specify the types of services that an
Auditor may not provide to its audit client. The following policies and
procedures comply with the requirements for pre-approval and provide a mechanism
by which




management of the Funds may request and secure pre-approval of audit and non-
audit services in an orderly manner with minimal disruption to normal business
operations.

Proposed services either may be pre-approved without consideration of specific
case-by-case services by the Audit Committees ("general pre-approval") or
require the specific pre-approval of the Audit Committees ("specific pre -
approval"). As set forth in these policies and procedures, unless a type of
service has received general pre-approval, it will require specific pre-approval
by the Audit Committees. Additionally, any fees exceeding 110% of estimated pre
- -approved fee levels provided at the time the service was pre-approved will also
require specific approval by the Audit Committees before payment is made. The
Audit Committees will also consider the impact of additional fees on the
Auditor's independence when determining whether to approve any additional fees
for previously pre-approved services.

The Audit Committees will annually review and generally pre-approve the services
that may be provided by each Auditor without obtaining specific pre-approval
from the Audit Committee. The term of any general pre-approval runs from the
date of such pre-approval through September 30th of the following year, unless
the Audit Committees consider a different period and state otherwise. The Audit
Committees will add to or subtract from the list of general pre-approved
services from time to time, based on subsequent determinations.

The purpose of these policies and procedures is to set forth the guidelines to
assist the Audit Committees in fulfilling their responsibilities.

II. Delegation

The Audit Committees may from time to time delegate pre-approval authority to
one or more of its members who are Independent Directors. All decisions to
pre-approve a service by a delegated member shall be reported to the Audit
Committee at its next quarterly meeting.

III. Audit Services

The annual audit services engagement terms will be subject to specific
pre-approval of the Audit Committees. Audit services include the annual
financial statement audit and other procedures such as tax provision work that
is required to be performed by the independent auditor to be able to form an
opinion on the Funds' financial statements. The Audit Committee will obtain,
review and consider sufficient information concerning the proposed Auditor to
make a reasonable evaluation of the Auditor's qualifications and independence.

In addition to the annual Audit services engagement, the Audit Committees may
grant general pre-approval for other audit services, which are those services
that only the independent auditor reasonably can provide. Other Audit services
may include services such as issuing consents for the inclusion of audited
financial statements with SEC registration statements, periodic reports and
other documents filed with the SEC or other documents issued in connection with
securities offerings.

IV. Non-Audit Services

The Audit Committees may provide general pre-approval of types of non-audit
services described in this Section IV to the Funds and its Service Affiliates if
the Audit Committees believe that the provision of the service will not impair
the independence of the Auditor, is consistent with the SEC's Rules on auditor
independence, and otherwise conforms to the Audit Committee's general principles
and policies as set forth herein.

The Audit Committees may provide specific pre-approval of any non-audit services
to the Funds and its Service Affiliates if the Audit Committees believe that the
provision of the service will not impair the independence of the auditor, is
consistent with the SEC Rules on auditor independence, and otherwise conforms to
the Audit Committees' general principles and policies as set forth herein.

Audit-Related Services

"Audit-related services" are assurance and related services that are reasonably
related to the performance of the audit or review of the Fund's financial
statements or that are traditionally performed by the independent




auditor. Audit-related services include, among others, accounting consultations
related to accounting, financial reporting or disclosure matters not classified
as "Audit services"; assistance with understanding and implementing new
accounting and financial reporting guidance from rulemaking authorities; and
agreed-upon procedures related to mergers, compliance with ratings agency
requirements and interfund lending activities.

Tax Services

"Tax services" include, but are not limited to, the review and signing of the
Funds' federal tax returns, the review of required distributions by the Funds
and consultations regarding tax matters such as the tax treatment of new
investments or the impact of new regulations. The Audit Committee will
scrutinize carefully the retention of the Auditor in connection with a
transaction initially recommended by the Auditor, the major business purpose of
which may be tax avoidance or the tax treatment of which may not be supported in
the Internal Revenue Code and related regulations. The Audit Committee will
consult with the Funds' Treasurer (or his or her designee) and may consult with
outside counsel or advisors as necessary to ensure the consistency of Tax
services rendered by the Auditor with the foregoing policy.

No Auditor shall represent any Fund or any Service Provider before a tax court,
district court or federal court of claims.

All Other Auditor Services

The Audit Committees may pre-approve non-audit services classified as "All other
services" that are not categorically prohibited by the SEC, as listed in Exhibit
1 to this policy.

V. Pre-Approval Fee Levels or Established Amounts

Pre-approval of estimated fees or established amounts for services to be
provided by the Auditor under general or specific pre-approval policies will be
set periodically by the Audit Committees. Any proposed fees exceeding 110% of
the maximum estimated pre-approved fees or established amounts for pre-approved
audit and non-audit services will be reported to the Audit Committees at the
quarterly Audit Committees meeting and will require specific approval by the
Audit Committees before payment is made. The Audit Committee will always factor
in the overall relationship of fees for audit and non-audit services in
determining whether to pre-approve any such services and in determining whether
to approve any additional fees exceeding 110% of the maximum pre-approved fees
or established amounts for previously pre-approved services.

VI. Procedures

On an annual basis, A I M Advisors, Inc. ("AIM") will submit to the Audit
Committees for general pre-approval, a list of non-audit services that the Funds
or Service Affiliates of the Funds may request from the Auditor. The list will
describe the non-audit services in reasonable detail and will include an
estimated range of fees and such other information as the Audit Committee may
request.

Each request for services to be provided by the Auditor under the general
pre-approval of the Audit Committees will be submitted to the Funds' Treasurer
(or his or her designee) and must include a detailed description of the services
to be rendered. The Treasurer or his or her designee will ensure that such
services are included within the list of services that have received the general
pre-approval of the Audit Committees. The Audit Committees will be informed at
the next quarterly scheduled Audit Committees meeting of any such services for
which the Auditor rendered an invoice and whether such services and fees had
been pre-approved and if so, by what means.

Each request to provide services that require specific approval by the Audit
Committees shall be submitted to the Audit Committees jointly by the Fund's
Treasurer or his or her designee and the Auditor, and must include a joint
statement that, in their view, such request is consistent with the policies and
procedures and the SEC Rules.

Non-audit services pursuant to the de minimis exception provided by the SEC
Rules will be promptly brought to the attention of the Audit Committees for
approval, including documentation that each of the conditions for this
exception, as set forth in the SEC Rules, has been satisfied.




On at least an annual basis, the Auditor will prepare a summary of all the
services provided to any entity in the investment company complex as defined in
section 2-01(f)(14) of Regulation S-X in sufficient detail as to the nature of
the engagement and the fees associated with those services.

The Audit Committees have designated the Funds' Treasurer to monitor the
performance of all services provided by the Auditor and to ensure such services
are in compliance with these policies and procedures. The Funds' Treasurer will
report to the Audit Committee on a periodic basis as to the results of such
monitoring. Both the Funds' Treasurer and management of AIM will immediately
report to the chairman of the Audit Committee any breach of these policies and
procedures that comes to the attention of the Funds' Treasurer or senior
management of AIM.

ITEM 11. CONTROLS AND PROCEDURES.

(a)       As of September 15, 2005, an evaluation was performed under the
          supervision and with the participation of the officers of the
          Registrant, including the PEO and PFO, to assess the effectiveness of
          the Registrant's disclosure controls and procedures, as that term is
          defined in Rule 30a-3(c) under the Investment Company Act of 1940 (the
          "Act"), as amended. Based on that evaluation, the Registrant's
          officers, including the PEO and PFO, concluded that, as of September

          reasonably designed to ensure: (1) that information required to be
          disclosed by the Registrant on Form N-CSR is recorded, processed,
          summarized and reported within the time periods specified by the rules
          and forms of the Securities and Exchange Commission; and (2) that
          material information relating to the Registrant is made known to the
          PEO and PFO as appropriate to allow timely decisions regarding
          required disclosure.

          financial reporting (as defined in Rule 30a-3(d) under the Act) that
