                                     Dear Shareholders:

                                     While the year covered by this report was difficult -- for long-time investors and veteran
                                     investment professionals alike -- economic conditions and market trends appeared much more
                                     favorable at the close of the fiscal year than at its start.
               [TAYLOR
                PHOTO]                   The 12 months ended August 31, 2009, included a sharp market sell-off that occurred in the
                                     second half of 2008. That downturn affected virtually all sectors, markets and investors. The
                                     decline had a number of causes, the most immediate being unprecedented turmoil in credit
                                     markets. Economic uncertainty prompted banks to hoard cash and reduce lending, and caused
            Philip Taylor            investors to shun short-term corporate debt. As a result, businesses found it difficult to fund
                                     their day-to-day operations, and the U.S. economy -- as well as economies around the globe --
                                     virtually froze briefly.

                                     INCREASED COMMUNICATION

                                     These developments prompted a greater-than-usual number of shareholders to contact me. Some
of you took the time to write a letter while others of you emailed me at phil@invescoaim.com.

   Many of you sought explanations for the decline in the value of your accounts, while others asked more general questions about
when the economy might improve. Your questions, comments and suggestions gave me better insight into what was on your minds, and I
was pleased that so many of you took the time to share your thoughts with me.

   As a result, Invesco Aim's investment professionals and I have increased our efforts to stay in touch with and share our views
with you. We increased the number of "Investment Perspectives" articles on our website, invescoaim.com. Through these articles,
we've tried to provide timely market commentary, general investor education information and sector updates. I hope you'll take a
moment to read them and let me know if you find them useful.

   To access your Fund's latest quarterly commentary, click on "Products and Performance" at the top of our website; next, select
"Mutual Funds"; and then click on "Quarterly Commentary."

   I also hope you've stayed in touch with your financial advisor. An experienced financial advisor who is familiar with your
individual investment goals, time horizon and risk tolerance can be a source of comfort and information during uncertain times. He
or she can monitor your investments to ensure they're on track and can prevent you from making impulsive short-term decisions that
may have adverse long-term consequences.

REASONS FOR OPTIMISM

The economy and equity markets reacted to a barrage of negative news during the year. Consumer spending -- which accounts for more
than two-thirds(1) of the U.S. economy -- was sluggish as unemployment rose; more workers worried about their job security; home and
portfolio values declined; and credit became more difficult to obtain.

   In his semiannual monetary policy report to Congress in late July, U.S. Federal Reserve Board Chairman Ben Bernanke summarized
the stresses and strains the U.S. and global economies suffered in late 2008 and early 2009. Importantly, he suggested that the
aggressive, coordinated actions taken by governments and central banks around the world finally may be yielding results. He
testified that:

   o  The pace of overall economic decline appears to have slowed significantly.

   o  Credit availability, for consumers and businesses, has improved noticeably.

   o  Investors' extreme risk aversion has eased somewhat.

   o  The decline in housing activity appears to have moderated.

   While these and other trends offer encouragement, uncertainties remain. Chairman Bernanke testified that he anticipates a gradual
recovery in 2010 with some acceleration in economic growth in 2011, together with subdued inflation over the next two years. His
considered judgment appears to be shared by investors who have begun to return, cautiously, to the equities market, causing major
U.S. stock-market indexes to bounce off their March lows.

                                     Dear Fellow Shareholders:

                                     Although the economy and financial markets have shown some signs of hope, investors remain
              [CROCKETT              rightfully cautious. Staying with an appropriately diversified investment program focused on
                PHOTO]               your individual long-term goals can be a wise course in such uncertain times. We believe the
                                     route to financial success is more like a marathon than a sprint.

                                        Please be assured that your Board continues to oversee the AIM Funds with a strong sense of
                                     responsibility for your money and your trust. As always, we seek to manage costs and enhance
           Bruce Crockett            performance in ways that put your interests first.

                                        We are near the end of a busy 2009 proxy season, during which Invesco Aim Advisors, Inc.'s
                                     proxy committee votes on your behalf on issues put to a shareholder vote by the companies whose
stock the Funds hold. This year, after careful case-by-case analysis by committee members and portfolio managers, the proxy
committee voted with corporate management less often than in previous years, focusing on the issues of board independence,
Say-On-Pay initiatives, and stock option re-pricing in light of the market's decline. The committee remained committed to supporting
non-binding Say-on-Pay proposals and abstaining from voting on social issues.

   At its June meeting, your Board reviewed and renewed the investment advisory contracts between the AIM Funds and Invesco Aim
Advisors, Inc. You can find the results of this rigorous annual process at invescoaim.com. Go to "Products & Performance" and click
on "Investment Advisory Agreement Renewals."

   The website also contains news and market information, investment education and planning information and current reports and
prospectuses for all the AIM Funds and I highly recommend it to you.

   You are always welcome to contact me at bruce@brucecrockett.com with any questions or concerns you may have. We look forward to
representing you and serving you in the coming months.

Sincerely,

NOTES TO FINANCIAL STATEMENTS

August 31, 2009

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

AIM Core Plus Bond 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 seven separate
portfolios, each authorized to issue an unlimited number of shares of beneficial
interest. The assets, liabilities and operations of each portfolio are accounted
for separately. Information presented in these financial statements pertains
only to the Fund. Matters affecting each portfolio or class will be voted on
exclusively by the shareholders of such portfolio or class.

  The Fund's investment objective is total return.

  The Fund currently consists of six different classes of shares: Class A, Class
B, Class C, Class R, Class Y and Institutional Class. Class A shares are sold
with a front-end sales charge unless certain waiver criteria are met and under
certain circumstances load waiver shares may be subject to contingent deferred
sales charges ("CDSC"). Class B shares and Class C shares are sold with a CDSC.
Class R, Class Y and Institutional Class shares are sold at net asset value.
Under certain circumstances, Class R shares are subject to a CDSC. Generally,
Class B shares will automatically convert to Class A shares on or about the
month-end which is at least eight years after the date of purchase.

  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.

        Debt obligations (including convertible bonds) and unlisted equities 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

15        AIM CORE PLUS BOND FUND



      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, including commercial paper, having 60
      days or less to maturity are recorded at amortized cost which approximates
      value. Debt securities are subject to interest rate and credit risks. In
      addition, all debt securities involve some risk of default with respect to
      interest and/or principal payments.

        A security listed or traded on an exchange (except convertible bonds) is
      valued at its last sales price or official closing price as of the close
      of the customary trading session on the exchange where the security is
      principally traded, or lacking any sales or official closing price on a
      particular day, the security may be valued at the closing bid price on
      that day. Securities traded in the over-the-counter market are valued
      based on prices furnished by independent pricing services or market
      makers. When such securities are valued by an independent pricing service
      they may be considered fair valued. 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 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 are valued 15
      minutes after the close of the customary trading session of the New York
      Stock Exchange ("NYSE").

        Investments in open-end 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 open-end and closed-end registered
      investment companies that trade on an exchange are valued at the last
      sales price or official closing price as of the close of the customary
      trading session on the exchange where the security is principally traded.

        Swap agreements are fair valued using an evaluated quote provided by an
      independent pricing service. Evaluated quotes provided by the pricing
      service are valued based on a model which may include end of day net
      present values, spreads, ratings, industry, and company performance.

        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. If market quotations are available and reliable for
      foreign exchange traded equity securities, the securities will be valued
      at the market quotations. Because trading hours for certain foreign
      securities end before the close of the NYSE, closing market quotations may
      become unreliable. If between the time trading ends on a particular
      security and the close of the customary trading session on the NYSE,
      events occur that are significant and make the closing price unreliable,
      the Fund may fair value the security. 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
      value as of the close of the NYSE. Foreign securities meeting the approved
      degree of certainty that the price is not reflective of current 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, American Depositary Receipts and
      domestic and foreign index futures. Foreign securities may have additional
      risks including exchange rate changes, potential for sharply devalued
      currencies and high inflation, political and economical upheaval, the
      relative lack of issuer information, relatively low market liquidity and
      the potential lack of strict financial and accounting controls and
      standards.

        Securities for which market prices are not provided by any of the above
      methods may be valued based upon quotes furnished by independent sources.
      The last bid price may be used to value equity securities and Corporate
      Loans. The mean between the last bid and asked prices may be used to value
      debt obligations other than Corporate Loans.

        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.

        Valuations change in response to many factors including the historical
      and prospective earnings of the issuer, the value of the issuer's assets,
      general economic conditions, interest rates, investor perceptions and
      market liquidity. Because of the inherent uncertainties of valuation, the
      values reflected in the financial statements may materially differ from
      the value received upon actual sale of those investments.

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. Paydown gains and losses on mortgage and asset-backed securities are
      recorded as adjustments to interest income. Dividend income is recorded on
      the ex-dividend date. Bond premiums and discounts are amortized and/or
      accreted for financial reporting purposes.

        The Fund may periodically participate in litigation related to Fund
      investments. As such, the Fund may receive proceeds from litigation
      settlements. Any proceeds received are included in the Statement of
      Operations as realized gain/loss for investments no longer held and as
      unrealized gain/loss for investments still held.

        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 realized and unrealized capital gains and losses to a
      class based on the relative net assets of each class. The Fund allocates
      income to a class based on the relative value of the settled shares of
      each class.

C.    COUNTRY DETERMINATION -- For the purposes of making investment selection
      decisions and presentation in the Schedule of Investments, the investment
      advisor 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

16        AIM CORE PLUS BOND FUND



      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 the United States of America, unless otherwise
      noted.

D.    DISTRIBUTIONS -- Distributions from income are declared daily and paid
      monthly. Distributions from net realized capital gain, if any, are
      generally paid annually and recorded on ex-dividend date. The Fund may
      elect to treat 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 to distribute substantially all of the
      Fund's taxable earnings to shareholders. As such, the Fund will not be
      subject to federal income taxes on otherwise taxable income (including net
      realized capital gain) that is distributed to shareholders. Therefore, no
      provision for federal income taxes is recorded in the financial
      statements.

        The Fund files tax returns in the U.S. Federal jurisdiction and certain
      other jurisdictions. Generally the Fund is subject to examinations by such
      taxing authorities for up to three years after the filing of the return
      for the tax period.

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.    ACCOUNTING ESTIMATES -- 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 by a
      significant amount. In addition, the Fund monitors for material events or
      transactions that may occur or become known after the period-end date and
      before the date the financial statements are released to print, which is
      generally 45 days from the period-end date.

H.    INDEMNIFICATIONS -- Under the Trust's organizational documents, each
      Trustee, officer, employee or other agent of the Trust 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, including the Fund's servicing agreements,
      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. The
      risk of material loss as a result of such indemnification claims is
      considered remote.

I.    OTHER RISKS -- The Funds may invest in obligations issued by agencies and
      instrumentalities of the U.S. Government that may vary in the level of
      support they receive from the government. The government may choose not to
      provide financial support to government sponsored agencies or
      instrumentalities if it is not legally obligated to do so. In this case,
      if the issuer defaulted, the underlying fund holding securities of such
      issuer might not be able to recover its investment from the U.S.
      Government. Many securities purchased by the Fund are not guaranteed by
      the U.S. Government.

J.    DOLLAR ROLL AND FORWARD COMMITMENT TRANSACTIONS -- The Fund may engage in
      dollar roll and forward commitment transactions with respect to mortgage-
      backed securities issued by GNMA, FNMA and FHLMC. These transactions are
      often conducted on a to be announced ("TBA") basis. In a TBA mortgage-
      backed transaction, the seller does not specify the particular securities
      to be delivered. Rather, a Fund agrees to accept any security that meets
      specified terms, such as an agreed upon issuer, coupon rate and terms of
      the underlying mortgages. TBA mortgage-backed transactions generally
      settle once a month on a specific date.

        In a dollar roll transaction, the Fund sells a mortgage-backed security
      held in the Fund to a financial institution such as a bank or broker-
      dealer, and simultaneously agrees to purchase a substantially similar
      security (same type, coupon and maturity) from the institution at an
      agreed upon price and future date. The mortgage-backed securities to be
      purchased will bear the same coupon as those sold, but generally will be
      collateralized by different pools of mortgages with different prepayment
      histories. Based on the typical structure of dollar roll transactions by
      the Fund, the dollar roll transactions are accounted for as financing
      transactions in which the Fund receives compensation as either a "fee" or
      a "drop". "Fee" income which is agreed upon amongst the parties at the
      commencement of the dollar roll and the "drop" which is the difference
      between the selling price and the repurchase price of the mortgage-backed
      securities are amortized to income. During the period between the sale and
      purchase settlement dates, the Fund will not be entitled to receive
      interest and principal payments on securities purchased and not yet
      settled. Proceeds of the sale may be invested in short-term instruments,
      and the income from these investments, together with any additional fee
      income received on the sale, could generate income for the Fund exceeding
      the yield on the security sold. Dollar roll transactions are considered
      borrowings under the 1940 Act.

        Forward commitment transactions involve commitments by the Fund to
      acquire or sell TBA mortgage-backed securities from/to a financial
      institution, such as a bank or broker-dealer at a specified future date
      and amount. The TBA mortgage-backed security is marked to market until
      settlement and the unrealized appreciation or depreciation is recorded in
      the statement of operations.

        At the time the Fund enters into the dollar roll or forward commitment
      transaction, mortgage-backed securities or other liquid assets held by the
      Fund having a dollar value equal to the purchase price or in an amount
      sufficient to honor the forward commitment will be segregated.

        Dollar roll transactions involve the risk that the market value of the
      securities retained by the Fund may decline below the price of the
      securities that the Fund has sold but is obligated to purchase under the
      agreement. In the event that the buyer of securities in a dollar roll
      transaction files for bankruptcy or becomes insolvent, the Fund's use of
      the proceeds from the sale of the securities may be restricted pending a
      determination by the other party, or its trustee or receiver, whether to
      enforce the Fund's obligation to purchase the securities. The return
      earned by the Fund with the proceeds of the dollar roll transaction may
      not exceed the return on the securities sold.

        Forward commitment transactions involve the risk that a counter-party to
      the transaction may fail to complete the transaction. If this occurs, the
      Fund may lose the opportunity to purchase or sell the security at the
      agreed upon price. Settlement dates of forward commitment transactions may
      be a month

17        AIM CORE PLUS BOND FUND



      or more after entering into these transactions and as a result the market
      values of the securities may vary from the purchase or sale prices.
      Therefore, forward commitment transactions may increase the Fund's overall
      interest rate exposure.

K.    FUTURES CONTRACTS -- The Fund may enter into futures contracts to manage
      exposure to interest rate, equity and market price movements and/or
      currency risks. A futures contract is an agreement between two parties to
      purchase or sell a specified underlying security, currency or commodity
      (or delivery of a cash settlement price, in the case of an index future)
      for a fixed price at a future date. The Fund currently invests only in
      exchange-traded futures and they are standardized as to maturity date and
      underlying financial instrument. Initial margin deposits required upon
      entering into futures contracts are satisfied by the segregation of
      specific securities or cash as collateral at the futures commission
      merchant (broker). During the period the futures contracts are open,
      changes in the value of the contracts are recognized as unrealized gains
      or losses by recalculating the value of the contracts on a daily basis.
      Subsequent or variation margin payments are received or made depending
      upon whether unrealized gains or losses are incurred. These amounts are
      reflected as receivables or payables on the Statement of Assets and
      Liabilities. When the contracts are closed or expire, the Fund recognizes
      a realized gain or loss equal to the difference between the proceeds from,
      or cost of, the closing transaction and the Fund's basis in the contract.
      The net realized gain (loss) and the change in unrealized gain (loss) on
      futures contracts held during the period is included on the Statement of
      Operations. The primary risks associated with futures contracts are market
      risk and the absence of a liquid secondary market. If the Fund were unable
      to liquidate a futures contract and/or enter into an offsetting closing
      transaction, the Fund would continue to be subject to market risk with
      respect to the value of the contracts and continue to be required to
      maintain the margin deposits on the futures contracts. Futures contracts
      have minimal counterparty risk since the exchange's clearinghouse, as
      counterparty to all exchange traded futures, guarantees the futures
      against default. Risks may exceed amounts recognized in the Statement of
      Assets and Liabilities.

L.    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.

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

The Trust has entered into a master investment advisory agreement with Invesco
Aim Advisors, Inc. (the "Advisor" or "Invesco Aim"). Under the terms of the
investment advisory agreement, the Fund pays an advisory fee to the Advisor
based on the annual rate of the Fund's average daily net assets as follows:

  Under the terms of a master sub-advisory agreement approved by shareholders of
the Fund between the Advisor and each of Invesco Asset Management Deutschland
GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan)
Limited, Invesco Australia Limited, Invesco Global Asset Management (N.A.),
Inc., Invesco Hong Kong Limited, Invesco Institutional (N.A.), Inc., Invesco
Senior Secured Management, Inc. and Invesco Trimark Ltd. (collectively, the
"Affiliated Sub-Advisors") the Advisor, not the Fund, may pay 40% of the fees
paid to the Advisor to any such Affiliated Sub-Advisor(s) that provide
discretionary investment management services to the Fund based on the percentage
of assets allocated to such Sub-Advisor(s).

  The Advisor 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, Class R,
Class Y and Institutional Class shares to 0.90%, 1.65%, 1.65%, 1.15%, 0.65% and
0.65% of average daily net assets, respectively, through at least June 30, 2010.
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
net annual operating expenses to exceed the numbers reflected above: (i)
interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary
items or non-routine items; (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 Invesco
Ltd. ("Invesco") 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, the Advisor has contractually agreed, through at least June 30, 2010,
to waive the advisory fee payable by the Fund in an amount equal to 100% of the
net advisory fees the Advisor receives from the affiliated money market funds on
investments by the Fund of uninvested cash in such affiliated money market
funds.

  For the period June 3, 2009 (commencement date) to August 31, 2009, the
Advisor waived advisory fees and reimbursed Fund level expenses of $94,496 and
reimbursed class level expenses of $397, $22, $22, $16, $19 and $24 for Class A,
Class B, Class C, Class R, Class Y and Institutional Class shares in proportion
to the relative net assets of such classes.

  The Trust has entered into a master administrative services agreement with
Invesco Aim pursuant to which the Fund has agreed to pay Invesco Aim for certain
administrative costs incurred in providing accounting services to the Fund. For
the period June 3, 2009 (commencement date) to August 31, 2009, expenses
incurred under the agreement are shown in the Statement of Operations as
administrative services fees.

  The Trust has entered into a transfer agency and service agreement with
Invesco Aim Investment Services, Inc. ("IAIS") pursuant to which the Fund has
agreed to pay IAIS a fee for providing transfer agency and shareholder services
to the Fund and reimburse IAIS for certain expenses incurred by IAIS in the
course of providing such services. IAIS may make payments to intermediaries that
provide omnibus account services, sub-accounting services and/or networking
services. All fees payable by IAIS to intermediaries that provide omnibus
account services or sub-accounting are charged back to the Fund, subject to
certain limitations approved by the Trust's Board of Trustees. For the period
June 3, 2009 (commencement date) to August 31, 2009, expenses incurred under the
agreement are shown in the Statement of Operations as transfer agent fees.


18        AIM CORE PLUS BOND FUND



  The Trust has entered into master distribution agreements with Invesco Aim
Distributors, Inc. ("IADI") to serve as the distributor for the Class A, Class
B, Class C, Class R, Class Y 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, Class C and Class R shares (collectively the
"Plans"). The Fund, pursuant to the Plans, pays IADI compensation at the annual
rate of 0.25% of the Fund's average daily net assets of Class A shares, 1.00% of
the average daily net assets of Class B and Class C shares and 0.50% of the
average daily net assets of Class R shares. Of the Plan payments, up to 0.25% of
the average daily net assets of each class of 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. Rules of the Financial Industry
Regulatory Authority ("FINRA") 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. For the period June 3, 2009 (commencement date) to August 31, 2009,
expenses incurred under the Plans are shown in the Statement of Operations as
distribution fees.

  Front-end sales commissions and 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. During the period June 3, 2009 (commencement
date) to August 31, 2009, IADI advised the Fund that IADI retained $145 in
front-end sales commissions from the sale of Class A shares and $0 from Class A,
Class B, Class C and Class R shares, respectively, for CDSC imposed on
redemptions by shareholders.

  Certain officers and trustees of the Trust are officers and directors of
Invesco Aim, IAIS and/or IADI.

NOTE 3--ADDITIONAL VALUATION INFORMATION

Generally Accepted Accounting Principles (GAAP) defines fair value as the price
that would be received to sell an asset or paid to transfer a liability in an
orderly transaction between market participants at the measurement date under
current market conditions. GAAP establishes a hierarchy that prioritizes the
inputs to valuation methods giving the highest priority to readily available
unadjusted quoted prices in an active market for identical assets (Level 1) and
the lowest priority to significant unobservable inputs (Level 3) generally when
market prices are not readily available or are unreliable. Based on the
valuation inputs, the securities or other investments are tiered into one of
three levels. Changes in valuation methods may result in transfers in or out of
an investment's assigned level:

  Level 1 -- Prices are determined using quoted prices in an active market for
             identical assets.

  Level 2 -- Prices are determined using other significant observable inputs.
             Observable inputs are inputs that other market participants may use
             in pricing a security. These may include quoted prices for similar
             securities, interest rates, prepayment speeds, credit risk and
             others.

  Level 3 -- Prices are determined using significant unobservable inputs. In
             situations where quoted prices or observable inputs are unavailable
             (for example, when there is little or no market activity for an
             investment at the end of the period), unobservable inputs may be
             used. Unobservable inputs reflect the Fund's own assumptions about
             the factors market participants would use in determining fair value
             of the securities or instruments and would be based on the best
             available information.

  The following is a summary of the tiered valuation input levels, as of the end
of the reporting period, August 31, 2009. The level assigned to the securities
valuations may not be an indication of the risk or liquidity associated with
investing in those securities. Because of the inherent uncertainties of
valuation, the values reflected in the financial statements may materially
differ from the value received upon actual sale of those investments.

NOTE 4--DERIVATIVE INVESTMENTS

Effective June 3, 2009 (commencement date), the Fund has adopted the provisions
of FASB Statement No. 161, Disclosures about Derivative Instruments and Hedging
Activities. The standard is intended to improve financial reporting about
derivative instruments and hedging activities by requiring enhanced disclosures
to enable investors to better understand their effects on an entity's financial
position and financial performance. The adoption of this provision has no impact
on the results of operations reported in the financial statements.

NOTE 5--TRUSTEES' AND OFFICERS' FEES AND BENEFITS

"Trustees' and Officers' Fees and Benefits" include amounts accrued by the Fund
to pay remuneration to certain Trustees and Officers of the Fund. Trustees have
the option to defer compensation payable by the Fund, and "Trustees' and
Officers' 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, certain 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 Officers'
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 period June 3, 2009 (commencement date) to August 31, 2009, the
Fund paid legal fees of $89 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 6--CASH BALANCES

The Fund may borrow for leveraging in an amount up to 5% of the Fund's total
assets (excluding the amount borrowed) at the time the borrowing is made. In
doing so, the Fund is permitted to temporarily carry a negative or overdrawn
balance in its account with The State Street Bank and Trust Company, 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 bank 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 Invesco Aim, not to exceed the contractually agreed
upon rate. A Fund may not purchase additional securities when any borrowings
from banks exceeds 5% of the Fund's total assets.

  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 net unrealized
appreciation (depreciation) difference is attributable primarily to futures
contracts and dollar roll transactions.

  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 has a capital loss carryforward as of August 31, 2009 which expires
as follows:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Trustees of AIM Counselor Series Trust
and Shareholders of AIM Core Plus Bond 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 Core Plus Bond Fund (one of the
funds constituting AIM Counselor Series Trust, hereafter referred to as the
"Fund") at August 31, 2009, the results of its operations, the changes in its
net assets and the financial highlights for the period June 3, 2009
(commencement date) through August 31, 2009, 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 audit. We
conducted our audit 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
audit, which included confirmation of securities at August 31, 2009 by
correspondence with the custodian and brokers, provides a reasonable basis for
our opinion.

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 or
contingent deferred sales charges on redemptions, and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and/or service
(12b-1) 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
actual ending account value and expenses of Class A, Class B, Class C, Class R
and Class Y shares in the below example are based on an investment of $1,000
invested on June 3, 2009 (commencement date) and held through August 31, 2009.
The hypothetical ending account value and expenses in the below example are
based on an investment of $1,000 invested at the beginning of the period and
held for the entire period March 1, 2009 through August 31, 2009.

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, June 3, 2009 (commencement
date) through August 31, 2009. Because the actual ending account value and
expense information in the example is not based upon a six month period, the
ending account value and expense information may not provide a meaningful
comparison to mutual funds that provide such information for a full six month
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 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 transaction 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 transaction 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 June 3, 2009 (commencement date) through August 31,
    2009, 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.
(2) Expenses are equal to the Fund's annualized expense ratio as indicated above
    multiplied by the average account value over the period, multiplied by 90
    (June 3, 2009 (commencement date) through August 31, 2009)/365. Because
    Class A, Class B, Class C, Class R and Class Y shares have not been in
    existence for a full six month period, the actual ending account value and
    expense information shown may not provide a meaningful comparison to fund
    expense information of classes that show such data for a full six month
    period and, because the actual ending account value and expense information
    in the expense example covers a short time period, return and expense data
    may not be indicative of return and expense data for longer time periods.
(3) Hypothetical expenses are equal to the annualized expense ratio indicated
    above multiplied by the average account value over the period, multiplied by
    184/365 to reflect a one-half year period. The hypothetical ending account
    value and expenses may be used to compare ongoing costs of investing in
    Class A, Class B, Class C, Class R and Class Y shares of the Fund and other
    funds because such data is based on a full six month period.

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 or
contingent deferred sales charges on redemptions, and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and/or service
(12b-1) 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
actual ending account value and expenses of Institutional Class shares in the
below example are based on an investment of $1,000 invested on June 3, 2009
(commencement date) and held through August 31, 2009. The hypothetical ending
account value and expenses in the below example are based on an investment of
$1,000 invested at the beginning of the period and held for the entire period
March 1, 2009 through August 31, 2009.

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, June 3, 2009 (commencement
date) through August 31, 2009. Because the actual ending account value and
expense information in the example is not based upon a six month period, the
ending account value and expense information may not provide a meaningful
comparison to mutual funds that provide such information for a full six month
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 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 June 3, 2009 (commencement date) through August 31,
    2009, 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.
(2) Expenses are equal to the Fund's annualized expense ratio as indicated above
    multiplied by the average account value over the period, multiplied by 90
    (June 3, 2009 (commencement date) through August 31, 2009)/365. Because
    Institutional Class shares have not been in existence for a full six month
    period, the actual ending account value and expense information shown may
    not provide a meaningful comparison to fund expense information of classes
    that show such data for a full six month period and, because the actual
    ending account value and expense information in the expense example covers a
    short time period, return and expense data may not be indicative of return
    and expense data for longer time periods.
(3) Hypothetical expenses are equal to the annualized expense ratio indicated
    above multiplied by the average account value over the period, multiplied by
    184/365 to reflect a one-half year period. The hypothetical ending account
    value and expenses may be used to compare ongoing costs of investing in
    Institutional Class shares of the Fund and other funds because such data is
    based on a full six month period.

                  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 18, 2006

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 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.

DELEGATION

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

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 either general or specific pre-approval of 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.

NON-AUDIT SERVICES

The Audit Committees may provide either general or 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's Rules on auditor
independence, and otherwise conforms to the Audit Committee's 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 Affiliate before a tax court,
district court or federal court of claims.

Under rules adopted by the Public Company Accounting Oversight Board and
approved by the SEC, in connection with seeking Audit Committee pre-approval of
permissible Tax services, the Auditor shall:

     1.   Describe in writing to the Audit Committees, which writing may be in
          the form of the proposed engagement letter:

               a.   The scope of the service, the fee structure for the
                    engagement, and any side letter or amendment to the
                    engagement letter, or any other agreement between the
                    Auditor and the Fund, relating to the service; and

               b.   Any compensation arrangement or other agreement, such as a
                    referral agreement, a referral fee or fee-sharing
                    arrangement, between the Auditor and any person (other than
                    the Fund) with respect to the promoting, marketing, or
                    recommending of a transaction covered by the service;

     2.   Discuss with the Audit Committees the potential effects of the
          services on the independence of the Auditor; and

     3.   Document the substance of its discussion with the Audit Committees.

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.



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.

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.

Each request to provide tax services under either the general or specific
pre-approval of the Audit Committees will describe in writing: (i) the scope of
the service, the fee structure for the engagement, and any side letter or
amendment to the engagement letter, or any other agreement between the Auditor
and the audit client, relating to the service; and (ii) any compensation
arrangement or other agreement between the Auditor and any person (other than
the audit client) with respect to the promoting, marketing, or recommending of a
transaction covered by the service. The Auditor will discuss with the Audit
Committees the potential effects of the services on the Auditor's independence
and will document the substance of the discussion.

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.

     PwC advised the Funds' Audit Committee that PwC had identified following
     matter for consideration under the SEC's auditor independence rules.

     PwC became aware that certain aspects of investment advisory services
     provided by a PwC network member Firm's Wealth Advisory Practice to its
     clients (generally high net worth individuals not associated with Invesco)
     were inconsistent with the SEC's auditor independence requirements of the
     SEC. The technical violations occurred as a result of professionals of the
     Wealth Advisory Practice making a single recommendation of an audit
     client's product to its clients rather than also identifying one or more
     suitable alternatives for the Wealth Advisory Practice's client to
     consider. The Wealth Advisory Practice also received commissions from the
     fund manager. With respect to Invesco and its affiliates, there were 33
     cases of single product recommendation and 20 cases of commissions received
     totaling approximately (pound)7,000. These violations occurred over a two
     year period and ended in November 2007.

     It should be noted that at no time did The Wealth Advisory Practice
     recommend products on behalf Invesco and its affiliates. Additionally,
     members of the audit engagement team were not aware of these violations or
     services; the advice provided was based on an understanding of the
     investment objectives of the clients of the Wealth Advisory Practice and
     not to promote the Company and its affiliates, and the volume and nature of
     the violations were insignificant. Although PwC received commissions, PwC
     derived no economic benefit from the commission as any commissions received
     were deducted from the time based fees charged to the investor client and
     created no incentive for PwC to recommend the investment.

     PwC advised the Audit Committee that it believes its independence had not
     been adversely affected as it related to the audits of the Funds by this
     matter. In reaching this conclusion, PwC noted that during the time of its
     audits, the engagement team was not aware of the services provided and
     noted the insignificance of the services provided. Based on the foregoing,
     PwC did not believe this matter affected PwC's ability to act objectively
     and impartially and to issue a report on financial statements as the Funds'
     independent auditor,



     and, believes that a reasonable investor with knowledge of all the facts
     would agree with this conclusion.

     Based upon PwC's review, discussion and representations above, the audit
     committee, in its business judgment, concurred with PwC's conclusions in
     relation to its independence.
