I'd like to take this opportunity to update you on recent market developments and provide some perspective and encouragement to fellow long-term investors. [TAYLOR PHOTO] MARKET OVERVIEW About a year ago or so, we saw warning signs of increasing economic ills -- a weakening housing market, rising inflation and slowing job growth, among others. Nonetheless, U.S. equity markets were performing Philip Taylor relatively well. But as the year progressed, the housing market deteriorated, energy prices rose, unemployment increased and the credit crunch grew more widespread. In response, the U.S. Federal Reserve cut short-term interest rate targets to stimulate economic growth and expand market liquidity.(1) Congress and the president worked together to enact an economic stimulus plan, one facet of which was to provide more than 112 million taxpayers with $92 billion in tax rebates.(2) Historically, actions such as these have stimulated economic growth. Unfortunately, other factors were simultaneously at work behind the scenes, and the market began to reveal the strain of those factors. HOW WE GOT HERE The market stresses we saw over the past year were the result of years of lax lending associated with the recent housing boom. Mortgage loans of questionable quality were bundled into hard-to-value securities that were sold to, and traded among, financial institutions. The value of those securities declined; more institutions sought to sell them and fewer institutions were willing to buy them. As a result, financial institutions' access to credit declined and the value of their holdings declined -- preventing normal trading among banks and other financial institutions. In October 2008, Congress enacted a plan, the Troubled Assets Relief Program, authorizing the U.S. Department of the Treasury to purchase up to $700 billion in troubled mortgage-related assets -- the largest and most direct effort to resolve a credit crisis in the last half century. INVESTING IN A VOLATILE MARKET Whether or not markets recover in the short term, the kind of volatility we've seen of late is a good reminder that in times of market uncertainty, it's wise to stay true to three timeless investing principles: o INVEST FOR THE LONG TERM. Short-term fluctuations have always been a reality of the markets. I urge you to stick to your investment plan and stay focused on your long-term goals. o DIVERSIFY. Although diversification doesn't eliminate the risk of loss or guarantee a profit, a careful selection of complementary asset classes may potentially cushion your portfolio against excessive volatility. o STAY FULLY INVESTED. Trying to time the market is a gamble, not an investment strategy. A sound investment strategy includes viewing market volatility as a matter of course, not a reason to panic. That leads me to a fourth principle we believe may be critical to your success: Work with a trusted financial advisor. An experienced advisor who knows your goals and situation can be your most valuable asset, particularly during times of market volatility. Your advisor can provide guidance and can monitor your investments to ensure they're on course. Recent market volatility has been disconcerting for everyone. Remember, however, that many of history's significant buying opportunities were the result of short-term economic crises that, in their time, were considered unprecedented. I believe current market volatility and uncertainty may represent a buying opportunity for patient, long-term investors. Invesco Aim's portfolio managers are working diligently on your behalf to capitalize on this situation. OUR NEW BRAND IDENTITY While market conditions are obviously at the top of everyone's mind, there are some significant changes I want to share with you: We have a new name and a new brand -- Invesco Aim.

Your Board of Trustees believes in the wisdom of a long-term perspective and consistent investment [CROCKETT discipline. We continue to put your interests first in the effort to improve investment performance, PHOTO] contain shareholder costs and uphold the highest ethical standards. We remain enthusiastic about the global reach and investment expertise that Invesco, a leading independent Bruce Crockett global investment management company, brings to the management of AIM Funds as the parent company of the advisors. The diverse investment strategies deployed throughout the worldwide network of Invesco investment centers has helped strengthen the management of many AIM Funds. The rebranding of the Funds' management company as Invesco Aim was followed by the launch of an upgraded, investor-friendly website (invescoaim.com); a new mountain logo using a Himalayan peak to symbolize stability, endurance, strength and longevity; and a new ad campaign. Emphasizing Invesco Aim's focus and investment quality, the ads will appear in financial publications such as Barron's and Investment News through the end of 2008. 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." We have recently completed another active proxy voting season during which we acted on your behalf to double the number of votes in favor of separating the roles of chairman and CEO at the companies whose shares your Funds hold. We also continued to support the movement for shareholders to have a bigger role in approving executive compensation, initiatives known as "say on pay." Like virtually all other mutual fund complexes, AIM Funds abstain from voting on social issues as a matter of policy, and I would be interested to hear your thoughts on this policy. As always, you are welcome to email your questions or comments to me at bruce@brucecrockett.com. The dialogue that has been established in this way has been instructive for your Board, and we want it to continue. Although the production schedule for Fund annual reports and prospectuses allows me to write these letters of general report and response just twice a year, please be assured that your comments are received, welcomed and heard in the interim. We look forward to hearing from you and to representing you. Sincerely, /S/ BRUCE L. CROCKETT Bruce L.

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 six separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently offers four different classes of shares: Class A, Class C, Class R and Institutional Class. Class A shares are sold with a front-end sales charge unless certain waived criteria are met and under certain circumstances load waiver shares may be subject to contingent deferred sales charges ("CDSC"). Class C shares are sold with a CDSC. Class R shares and Institutional Class shares are sold at net asset value. Under certain circumstances, Class R shares are subject to a CDSC. 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 objectives are to provide a high level of current income and, secondarily, preservation of capital. The following is a summary of the significant accounting policies followed by the Fund in the preparation of its financial statements. A. SECURITY VALUATIONS -- Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data. 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 may be valued at the closing bid price on that day. Securities traded in the over-the-counter market (but not securities reported on the NASDAQ Stock Exchange) are valued based on the prices furnished by independent pricing services, in which case the securities may be considered fair valued, or by market makers. Each security reported on the NASDAQ Stock Exchange 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 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. 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 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. 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 may 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 and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Securities for which market quotations are not readily available or are 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. 26 AIM FLOATING RATE FUND B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transaction 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 the settlement date. Facility fees received may be amortized over the life of the loan. 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 as 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 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. H. INDEMNIFICATIONS -- 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. The risk of material loss as a result of such indemnification claims is considered remote. I. OTHER RISKS -- The Fund may invest all or substantially of its assets in senior secured floating rate loans, senior secured debt securities or other securities rated below investment grade. These securities are generally considered to have speculative characteristics and are subject to greater risk of loss of principal and interest than higher rated securities. The value of lower quality debt securities and floating rate loans can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market or economic developments. The Fund invests in corporate loans from U.S. or non-U.S. companies (the "Borrowers"). The investment of the Fund in a corporate loan may take the form of participation interests or assignments. If the Fund purchases a participation interest from a syndicate of lenders ("Lenders") or one of the participants in the syndicate ("Participant"), one or more of which administers the loan on behalf of all the Lenders (the "Agent Bank"), the Fund would be required to rely on the Lender that sold the participation interest not only for the enforcement of the Fund's rights against the Borrower but also for the receipt and processing of payments due to the Fund under the corporate loans. As such, the Fund is subject to the credit risk of the Borrower and the Participant. Lenders and Participants interposed between the Fund and a Borrower, together with Agent Banks, are referred to as "Intermediate Participants". J. REDEMPTION FEES -- The Fund has a 2% redemption fee that is to be retained by the Fund to offset transaction costs and other expenses associated with short-term redemptions and exchanges. The fee, subject to certain exceptions, is imposed on certain redemptions, including exchanges of shares held less than 30 days. The redemption fee is recorded as an increase in shareholder capital and is allocated among the share classes based on the relative net assets of each class. 27 AIM FLOATING RATE FUND K. CASH AND CASH EQUIVALENTS -- For the purposes of the Statement of Cash Flows the Fund defines Cash and Cash Equivalents as cash (including foreign currency), money market funds and other investments held in lieu of cash and excludes investments made with cash collateral received. L. SECURITIES PURCHASED ON A WHEN-ISSUED AND DELAYED DELIVERY BASIS -- The Fund may purchase and sell interests in Corporate Loans and Corporate Debt Securities and other portfolio securities on a when-issued and delayed delivery basis, with payment and delivery scheduled for a future date. No income accrues to the Fund on such interests or securities in connection with such transactions prior to the date the Fund actually takes delivery of such interests or securities. These transactions are subject to market fluctuations and are subject to the risk that the value at delivery may be more or less than the trade date purchase price. Although the Fund will generally purchase these securities with the intention of acquiring such securities, they may sell such securities prior to the settlement date. 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: <Table> <Caption> AVERAGE NET ASSETS RATE - ------------------------------------------------------------------- First $500 million 0.65% - ------------------------------------------------------------------- Next $4.5 billion 0.60% - ------------------------------------------------------------------- Next $5 billion 0.575% - ------------------------------------------------------------------- Over $10 billion 0.55% ___________________________________________________________________ =================================================================== </Table> Under the terms of a new master sub-advisory agreement approved by shareholders of the Fund, effective May 1, 2008, 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). Previously, the Advisor had entered in a sub-advisory agreement with Invesco Senior Secured Management, Inc. ("ISSM"). Under the terms of a sub-advisory agreement, the Advisor paid ISSM 40% of the amount of the Advisor's compensation on the sub-advised assets annually. This agreement terminated on May 1, 2008. 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 C, Class R and Institutional Class shares to 1.50%, 2.00%, 1.75% and 1.25% of average daily net assets, respectively at least through June 30, 2009. 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; and (v) 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. These credits are used to pay certain expenses incurred by the Fund. The Advisor did not waive fees and/or reimburse expenses during the period under this expense limitation. Further, the Advisor has contractually agreed, through at least June 30, 2009, 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 year ended August 31, 2008, the Advisor waived advisory fees of $9,954. At the request of the Trustees of the Trust, Invesco 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, 2008, Invesco reimbursed expenses of the Fund in the amount of $5,332. 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 year ended August 31, 2008, 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 year ended August 31, 2008, expenses incurred under the agreement are shown in the Statement of Operations as transfer agent fees. The Trust has entered into master distribution agreements with Invesco Aim Distributors, Inc. ("IADI") to serve as the distributor for the Class A, Class C, Class R 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 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, 0.75% of the average daily net assets of 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 28 AIM FLOATING RATE FUND 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 year ended August 31, 2008, 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 year ended August 31, 2008, IADI advised the Fund that IADI retained $23,496 in front-end sales commissions from the sale of Class A shares and $27,723, $63,665 and $0 from Class A, Class C and Class R shares, respectively, for CDSC imposed upon redemptions by shareholders. Certain officers and trustees of the Trust are officers and directors of Invesco Aim, IAIS and/or IADI. NOTE 3--EXPENSE OFFSET ARRANGEMENTS The expense offset arrangements are comprised of (i) transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions and (ii) custodian credits which result from periodic overnight cash balances at the custodian. For the year ended August 31, 2008, the Fund received credits from these arrangements, which resulted in the reduction of the Fund's total expenses of $11,070. NOTE 4--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 year ended August 31, 2008, the Fund paid legal fees of $3,059 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 5--BORROWINGS The Fund is a party to a committed line of credit facility with a syndicate administered by JPMorgan Chase Bank. The Fund may borrow up to the lesser of (i) $50,000,000, or (ii) the limits set by its prospectus for borrowings. The Fund is charged a commitment fee of 0.05% on the unused balance of the committed line. During the year ended August 31, 2008, the Fund had average borrowings for the 122 days the borrowings were outstanding of $9,522,131, with a weighted average interest rate of 4.36% and interest expense of $138,499. The Fund is permitted to temporarily carry a negative or overdrawn balance in its account with 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. NOTE 6--UNFUNDED LOAN COMMITMENTS As of August 31, 2008, the Fund had unfunded loan commitments of $5,382,435, which could be extended at the option of the borrower, pursuant to the following loan agreements with the following borrowers: <Table> <Caption> UNFUNDED BORROWER COMMITMENTS - --------------------------------------------------------------------------------------------------------- Bally Tech Alliance Term Loan $2,216,250 - --------------------------------------------------------------------------------------------------------- CCS Corp.

The Fund's net unrealized appreciation (depreciation) difference is attributable primarily to wash sales. 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 benefits. 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, 2008 which expires as follows: <Table> <Caption> CAPITAL LOSS EXPIRATION CARRYFORWARD* - ----------------------------------------------------------------------------------------------- August 31, 2009 $10,188,057 - ----------------------------------------------------------------------------------------------- August 31, 2010 21,273,718 - ----------------------------------------------------------------------------------------------- August 31, 2011 10,298,295 - ----------------------------------------------------------------------------------------------- August 31, 2012 2,745,717 - ----------------------------------------------------------------------------------------------- August 31, 2013 5,482,284 - ----------------------------------------------------------------------------------------------- August 31, 2014 2,498,917 - ----------------------------------------------------------------------------------------------- August 31, 2016 1,685,685 =============================================================================================== Total capital loss carryforward $54,172,673 _______________________________________________________________________________________________ =============================================================================================== </Table> * Capital loss carryforward as of the date listed above is reduced for limitations, if any, to the extent required by the Internal Revenue Code. NOTE 8--INVESTMENT SECURITIES The aggregate amount of investment securities (other than short-term securities, U.S. Treasury obligations and money market funds, if any) purchased and sold by the Fund during the year ended August 31, 2008 was $186,997,507 and $227,198,736, respectively.

PENDING LITIGATION AND REGULATORY INQUIRIES AIM Floating Rate Fund, along with numerous unrelated funds and financial institutions, has been named as a defendant in two private civil lawsuits filed in the United States Bankruptcy Court, Southern District of New York (Enron Corp. v. J.P. Morgan Securities, Inc., et al., Case No. 01-16034(AJG) and Adelphia Communications Corp. and its Affiliate Debtors in Possession and Official Committee of Unsecured Creditors of Adelphia v. Bank of America, individually and as Agent for various Banks Party to Credit Agreements, et al., Case No. 02-41729). These lawsuits seek, respectively, avoidance of certain payments made by Enron Corp. and avoidance of certain loans to Adelphia Communications Corp. The Enron lawsuit alleges that payments made to the Fund and other creditors to prepay and/or redeem certain commercial paper prior to its maturity were preferential transfers. The amount sought to be recovered from the Fund in the Enron lawsuit is the aggregate amount of the repurchases of Enron's commercial paper from the fund during the 90 days prior to the filing by Enron of a bankruptcy petition (approximately $10 million) plus interest and Enron's court costs. On September 19, 2008, a group of defendants, including the Fund, reached a settlement in principal with Enron that is subject to approval by the Bankruptcy Court for approximately 13% of Enron's demand; and on that date, the Fund booked a settlement reserve for such amount. The Adelphia lawsuit alleges that the purchasers of Adelphia's bank debt knew, or should have known, that the loan proceeds would not benefit Adelphia, but instead would be used to enrich Adelphia insiders. The amount sought to be recovered from the Fund in the Adelphia lawsuit is not specified. On June 17, 2008, the Court in the Adelphia lawsuit granted, in its entirety, the Motion to Dismiss filed by a group of defendants that includes the Fund and dismissed all of Adelphia's claims against it. Adelphia has the right to appeal 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 Invesco Aim and IADI (Order No. 05- 1318). The WVASC makes findings of fact that Invesco Aim and IADI entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and IADI violated the West Virginia securities laws. The WVASC orders Invesco Aim and IADI to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, Invesco Funds Group, Inc. ("IFG"), Invesco Aim, IADI 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; and - that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and the Employee Retirement Income Security Act of 1974, as amended ("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. The case pending in Illinois State Court regarding fair value pricing was dismissed with prejudice on May 6, 2008. All lawsuits based on allegations of market timing, late trading and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court"). Pursuant to an Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties: (i) a Consolidated Amended Class Action Complaint purportedly brought on behalf of shareholders of the AIM Funds; (ii) a Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint for Violations of ERISA purportedly brought on behalf of participants in the Invesco 401(k) plan. Based on orders issued by the MDL Court, all claims asserted against the AIM Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the Consolidated Amended Fund Derivative Complaint. On September 15, 2006, the MDL Court granted the Invesco defendants' motion to dismiss the Amended Class Action Complaint for Violations of ERISA and dismissed such Complaint. Plaintiff appealed this ruling. On June 16, 2008, the Fourth Circuit Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings. IFG, Invesco Aim, IADI 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, among others, 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 security holders. IFG, Invesco Aim and IADI have advised the Fund that they are providing full cooperation with respect to these inquiries. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, Invesco Aim and/or related entities and individuals in the future. At the present time, except with respect to the settlement of the Enron litigation, management of Invesco Aim and the Fund are unable to estimate the impact, if any, that the outcome of the Pending Litigation and Regulatory Inquiries described above may have on Invesco Aim, IADI or the Fund. 33 AIM FLOATING RATE FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of AIM Counselor Series Trust and Shareholders of AIM Floating Rate 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 Floating Rate Fund (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2008, 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, its cash flows for the year 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, 2008 by correspondence with the custodian and intermediate participants, provide a reasonable basis for our opinion. PRICEWATERHOUSECOOPERS LLP October 20, 2008 Houston, Texas 34 AIM FLOATING RATE 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 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 example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2008, through August 31, 2008. 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 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. <Table> <Caption> - --------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2) (08/31/08) PERIOD(2) RATIO - --------------------------------------------------------------------------------------------------- A $1,000.00 $1,043.80 $7.40 $1,017.90 $7.30 1.44% - --------------------------------------------------------------------------------------------------- C 1,000.00 1,041.20 9.95 1,015.38 9.83 1.94 - --------------------------------------------------------------------------------------------------- R 1,000.00 1,041.20 8.67 1,016.64 8.57 1.69 - --------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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.

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, 2008, through August 31, 2008. 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 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.

PHOTO] MARKET OVERVIEW Philip Taylor About a year ago or so, we saw warning signs of increasing economic ills -- a weakening housing market, rising inflation and slowing job growth, among others. Nonetheless, U.S. equity markets were performing relatively well. But as the year progressed, the housing market deteriorated, energy prices rose, unemployment increased and the credit crunch grew more widespread. In response, the U.S. Federal Reserve cut short-term interest rate targets to stimulate economic growth and expand market liquidity.(1) Congress and the president worked together to enact an economic stimulus plan, one facet of which was to provide more than 112 million taxpayers with $92 billion in tax rebates.(2) Historically, actions such as these have stimulated economic growth. Unfortunately, other factors were simultaneously at work behind the scenes, and the market began to reveal the strain of those factors. HOW WE GOT HERE The market stresses we saw over the past year were the result of years of lax lending associated with the recent housing boom. Mortgage loans of questionable quality were bundled into hard-to-value securities that were sold to, and traded among, financial institutions. The value of those securities declined; more institutions sought to sell them and fewer institutions were willing to buy them. As a result, financial institutions' access to credit declined and the value of their holdings declined -- preventing normal trading among banks and other financial institutions. In October 2008, Congress enacted a plan, the Troubled Assets Relief Program, authorizing the U.S. Department of the Treasury to purchase up to $700 billion in troubled mortgage-related assets -- the largest and most direct effort to resolve a credit crisis in the last half century. INVESTING IN A VOLATILE MARKET Whether or not markets recover in the short term, the kind of volatility we've seen of late is a good reminder that in times of market uncertainty, it's wise to stay true to three timeless investing principles: o INVEST FOR THE LONG TERM. Short-term fluctuations have always been a reality of the markets. I urge you to stick to your investment plan and stay focused on your long-term goals. o DIVERSIFY. Although diversification doesn't eliminate the risk of loss or guarantee a profit, a careful selection of complementary asset classes may potentially cushion your portfolio against excessive volatility. o STAY FULLY INVESTED. Trying to time the market is a gamble, not an investment strategy. A sound investment strategy includes viewing market volatility as a matter of course, not a reason to panic. That leads me to a fourth principle we believe may be critical to your success: Work with a trusted financial advisor. An experienced advisor who knows your goals and situation can be your most valuable asset, particularly during times of market volatility. Your advisor can provide guidance and can monitor your investments to ensure they're on course. Recent market volatility has been disconcerting for everyone. Remember, however, that many of history's significant buying opportunities were the result of short-term economic crises that, in their time, were considered unprecedented. I believe current market volatility and uncertainty may represent a buying opportunity for patient, long-term investors. Invesco Aim's portfolio managers are working diligently on your behalf to capitalize on this situation. OUR NEW BRAND IDENTITY While market conditions are obviously at the top of everyone's mind, there are some significant changes I want to share with you: We have a new name and a new brand -- Invesco Aim. Our parent company, Invesco Ltd., is one of the world's largest and most diversified global investment managers with $450 billion in assets under management as of August 31, 2008.

This provides you: o Diversified investment strategies from distinct management teams around the globe. o A range of investment products to help you achieve your financial goals. o The peace of mind professional asset management and a diversified investment portfolio can provide. While our name may have changed, our commitment to putting shareholders first, helping clients achieve their investment goals and providing excellent customer service will never change. If you have questions about this report or your account, please contact one of our client service representatives at 800 959 4246. Thank you for your continued confidence, and we look forward to serving you. Sincerely, /S/ PHILIP TAYLOR Philip Taylor Senior Managing Director, Invesco Ltd.

We remain enthusiastic about the global reach and investment expertise that Invesco, a leading independent global investment management company, brings to the management of AIM Funds as the parent company of the advisors. The diverse investment strategies deployed throughout the worldwide network of Invesco investment centers has helped strengthen the management of many AIM Funds. The rebranding of the Funds' management company as Invesco new mountain logo using a Himalayan peak to symbolize stability, endurance, strength and longevity; and a new ad campaign. Emphasizing Invesco Aim's focus and investment quality, the ads will appear in financial publications such as Barron's and Investment News through the end of 2008. 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." We have recently completed another active proxy voting season during which we acted on your behalf to double the number of votes in favor of separating the roles of chairman and CEO at the companies whose shares your Funds hold. We also continued to support the movement for shareholders to have a bigger role in approving executive compensation, initiatives known as "say on pay." Like virtually all other mutual fund complexes, AIM Funds abstain from voting on social issues as a matter of policy, and I would be interested to hear your thoughts on this policy. As always, you are welcome to email your questions or comments to me at bruce@brucecrockett.com. The dialogue that has been established in this way has been instructive for your Board, and we want it to continue. Although the production schedule for Fund annual reports and prospectuses allows me to write these letters of general report and response just twice a year, please be assured that your comments are received, welcomed and heard in the interim. We look forward to hearing from you and to representing you. Sincerely, /S/ BRUCE L. CROCKETT Bruce L.

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 six separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently offers four different classes of shares: Class A, Class B, Class C 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. Institutional Class shares are sold at net asset value. 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. 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 capital growth. 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 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 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 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. 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 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. 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 may 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 and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Securities for which market quotations are not readily available or are 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. Dividend income is recorded on the ex-dividend date. Bond premiums and discounts are amortized and/or accreted for financial reporting purposes. 15 AIM MULTI-SECTOR FUND The Fund may periodically participate in litigation related to Fund investments. As such, the Fund may receive proceeds from litigation settlements. Any proceeds as 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 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, 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 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 and 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. H. INDEMNIFICATIONS -- 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. The risk of material loss as a result of such indemnification claims is considered remote. I. SECURITIES LENDING -- 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 by the securities lending provider. Such collateral will be cash or debt securities issued or guaranteed by the U.S. Government or any of its sponsored agencies. Cash collateral received in connection with these loans is invested in short-term money market instruments or affiliated money market funds and is shown as such on the Schedule of Investments. 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 any loss on the collateral invested. Dividends received on cash collateral investments for securities lending transactions, which are net of compensation to counterparties, is included in Dividends from affiliates on the Statement of Operations. The aggregate value of securities out on loan is shown as a footnote on the Statement of Assets and Liabilities, if any. J. 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 16 AIM MULTI-SECTOR FUND (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. The Fund may invest in foreign securities which may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. K. 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. Fluctuations in the value of these contracts are recorded as unrealized appreciation (depreciation) until the contracts are closed. When these contracts are closed, realized gains (losses) are recorded. Realized and unrealized gains and losses on these contracts are included in the Statement of Operations. The Fund could be exposed to risk, which may be in excess of the amount reflected in the Statement of Assets and Liabilities, if counterparties to the contracts are unable to meet the terms of their contracts or if the value of the foreign currency changes unfavorably. L. FUTURES CONTRACTS -- The Fund may purchase or sell futures contracts. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities as collateral for the account of the broker (the Fund's agent in acquiring the futures position). During the period the futures contracts are open, changes in the value of the contracts are recognized as unrealized gains or losses by recalculating the value of the contracts on a daily basis. Variation margin payments are received or made depending upon whether unrealized gains or losses are incurred. When the contracts are closed, the Fund recognizes a realized gain or loss equal to the difference between the proceeds from, or cost of, the closing transaction and the Fund's basis in the contract. 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. Risks may exceed amounts recognized in the Statement of Assets and Liabilities. M. 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 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: <Table> <Caption> AVERAGE NET ASSETS RATE - ------------------------------------------------------------------- First $250 million 0.695% - ------------------------------------------------------------------- Next $250 million 0.67% - ------------------------------------------------------------------- Next $500 million 0.645% - ------------------------------------------------------------------- Next $1.5 billion 0.62% - ------------------------------------------------------------------- Next $2.5 billion 0.595% - ------------------------------------------------------------------- Next $2.5 billion 0.57% - ------------------------------------------------------------------- Next $2.5 billion 0.545% - ------------------------------------------------------------------- Over $10 billion 0.52% ___________________________________________________________________ =================================================================== </Table> Under the terms of a master sub-advisory agreement approved by shareholders of the Fund, effective May 1, 2008, 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, through at least June 30, 2009, 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 (excluding investments of cash collateral from securities lending) in such affiliated money market funds. For the year ended August 31, 2008, the Advisor waived advisory fees of $55,104. At the request of the Trustees of the Trust, Invesco Ltd. ("Invesco") 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, 2008, Invesco reimbursed expenses of the Fund in the amount of $9,201. 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 year ended August 31, 2008, 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 17 AIM MULTI-SECTOR FUND limitations approved by the Trust's Board of Trustees. For the year ended August 31, 2008, expenses incurred under the agreement are shown in the Statement of Operations as transfer agent fees. 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 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 Plans, pays IADI 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. 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 year ended August 31, 2008, 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 year ended August 31, 2008, IADI advised the Fund that IADI retained $119,391 in front-end sales commissions from the sale of Class A shares and $1,718, $115,393 and $12,413 from Class A, Class B and Class C 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--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, for the year ended August 31, 2008, the Fund engaged in securities sales of $2,327,611, which resulted in net realized gains of $128,799, and securities purchases of $3,063,233. NOTE 4--EXPENSE OFFSET ARRANGEMENTS The expense offset arrangements are comprised of (i) transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions and (ii) custodian credits which result from periodic overnight cash balances at the custodian. For the year ended August 31, 2008, the Fund received credits from these arrangements, which resulted in the reduction of the Fund's total expenses of $26,790. 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 year ended August 31, 2008, the Fund paid legal fees of $4,108 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 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. 18 AIM MULTI-SECTOR FUND NOTE 7--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS DISTRIBUTIONS TO SHAREHOLDERS: The tax character of distributions paid during the years ended August 31, 2008 and 2007 was as follows: <Table> <Caption> 2008 2007 - -------------------------------------------------------------------------------------------------------- Ordinary income $ 6,513,488 $ 4,759,869 - -------------------------------------------------------------------------------------------------------- Long-term capital gain 32,758,310 5,485,862 ======================================================================================================== Total distributions $39,271,798 $10,245,731 ________________________________________________________________________________________________________ ======================================================================================================== </Table> TAX COMPONENTS OF NET ASSETS: As of August 31, 2008, the components of net assets on a tax basis were as follows: <Table> <Caption> 2008 - ------------------------------------------------------------------------------------------------ Undistributed ordinary income $ 1,403,661 - ------------------------------------------------------------------------------------------------ Undistributed long-term gain 18,782,901 - ------------------------------------------------------------------------------------------------ Net unrealized appreciation -- investments 10,109 - ------------------------------------------------------------------------------------------------ Net unrealized appreciation -- other investments 1,209 - ------------------------------------------------------------------------------------------------ Temporary book/tax differences (44,324) - ------------------------------------------------------------------------------------------------ Post-October currency loss deferral (281,338) - ------------------------------------------------------------------------------------------------ Shares of beneficial interest 704,451,954 ================================================================================================ Total net assets $724,324,172 ________________________________________________________________________________________________ ================================================================================================ </Table> 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 depreciation difference is attributable primarily to wash sales. 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 benefits. The Fund does not have a capital loss carryforward at period-end.

Cost of investments on a tax basis includes the adjustments for financial reporting purposes as of the most recently completed Federal income tax reporting period end. <Table> <Caption> UNREALIZED APPRECIATION (DEPRECIATION) OF INVESTMENT SECURITIES ON A TAX BASIS - ------------------------------------------------------------------------------------------------ Aggregate unrealized appreciation of investment securities $ 92,166,801 - ------------------------------------------------------------------------------------------------ Aggregate unrealized (depreciation) of investment securities (92,156,692) ================================================================================================ Net unrealized appreciation of investment securities $ 10,109 ________________________________________________________________________________________________ ================================================================================================ Cost of investments for tax purposes is $774,015,341. </Table> NOTE 10--RECLASSIFICATION OF PERMANENT DIFFERENCES Primarily as a result of differing book/tax treatment of foreign currency transactions on August 31, 2008, undistributed net investment income was decreased by $210,702, undistributed net realized gain was increased by $226,932 and shares of beneficial interest decreased by $16,230. This reclassification had no effect on the net assets of the Fund. 19 AIM MULTI-SECTOR FUND NOTE 11--SHARE INFORMATION <Table> <Caption> CHANGES IN SHARES OUTSTANDING - ------------------------------------------------------------------------------------------------------------------------- YEAR ENDED AUGUST 31, ------------------------------------------------------------- 2008(a) 2007 ---------------------------- ---------------------------- SHARES AMOUNT SHARES AMOUNT - ------------------------------------------------------------------------------------------------------------------------- Sold: Class A 3,807,565 $ 104,448,073 8,857,649 $ 246,329,341 - ------------------------------------------------------------------------------------------------------------------------- Class B 616,606 16,114,652 945,270 25,228,289 - ------------------------------------------------------------------------------------------------------------------------- Class C 558,328 14,810,636 1,173,932 31,617,738 - ------------------------------------------------------------------------------------------------------------------------- Institutional Class 614,220 17,320,624 2,336,012 65,700,462 ========================================================================================================================= Issued as reinvestment of dividends: Class A 781,183 21,599,713 214,975 5,918,251 - ------------------------------------------------------------------------------------------------------------------------- Class B 140,981 3,755,744 36,506 976,912 - ------------------------------------------------------------------------------------------------------------------------- Class C 161,954 4,312,829 35,743 956,140 - ------------------------------------------------------------------------------------------------------------------------- Institutional Class 278,854 7,833,000 66,387 1,848,212 ========================================================================================================================= Automatic conversion of Class B shares to Class A shares: Class A 339,068 9,189,273 192,233 5,408,042 - ------------------------------------------------------------------------------------------------------------------------- Class B (352,600) (9,189,273) (198,289) (5,408,042) ========================================================================================================================= Reacquired: Class A (5,981,685) (162,259,632) (3,874,344) (108,402,169) - ------------------------------------------------------------------------------------------------------------------------- Class B (708,031) (18,408,222) (641,576) (17,269,681) - ------------------------------------------------------------------------------------------------------------------------- Class C (793,160) (20,524,920) (629,576) (17,031,478) - ------------------------------------------------------------------------------------------------------------------------- Institutional Class (414,377) (11,252,555) (191,475) (5,731,946) ========================================================================================================================= (951,094) $ (22,250,058) 8,323,447 $ 230,140,071 _________________________________________________________________________________________________________________________ ========================================================================================================================= </Table> (a) There are entities that are record owners of more than 5% of the outstanding shares of the Fund and in the aggregate own 29% of the outstanding shares of the Fund.

The Trust has no knowledge as to whether all or any portion of the shares owned of record by these entities are also owned beneficially. In addition, 20% of the outstanding shares of the Fund are owned by affiliated mutual funds. Affiliated mutual funds are other mutual funds that are also advised by Invesco Aim. 20 AIM MULTI-SECTOR FUND NOTE 12--FINANCIAL HIGHLIGHTS The following schedule presents financial highlights for a share of the Fund outstanding throughout the periods indicated. <Table> <Caption> INCOME (LOSS) FROM INVESTMENT OPERATIONS --------------------------------------- DISTRIBUTIONS NET GAINS ---------------------------------------- NET ASSET NET (LOSSES) DIVIDEND DISTRIBUTIONS VALUE, INVESTMENT ON SECURITIES TOTAL FROM FROM NET FROM NET NET ASSET BEGINNING INCOME (BOTH REALIZED INVESTMENT INVESTMENT REALIZED TOTAL VALUE, END OF PERIOD (LOSS) AND UNREALIZED) OPERATIONS INCOME GAINS DISTRIBUTIONS OF PERIOD -

PENDING LITIGATION AND REGULATORY INQUIRIES 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 Invesco Aim and IADI (Order No. 05- 1318). The WVASC makes findings of fact that Invesco Aim and IADI entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and IADI violated the West Virginia securities laws. The WVASC orders Invesco Aim and IADI to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, Invesco Funds Group, Inc. ("IFG"), Invesco Aim, IADI 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; and - that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and the Employee Retirement Income Security Act of 1974, as amended ("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. The case pending in Illinois State Court regarding fair value pricing was dismissed with prejudice on May 6, 2008. 21 AIM MULTI-SECTOR FUND NOTE 13--LEGAL PROCEEDINGS--(CONTINUED) All lawsuits based on allegations of market timing, late trading and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court"). Pursuant to an Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties: (i) a Consolidated Amended Class Action Complaint purportedly brought on behalf of shareholders of the AIM Funds; (ii) a Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint for Violations of ERISA purportedly brought on behalf of participants in the Invesco 401(k) plan. Based on orders issued by the MDL Court, all claims asserted against the AIM Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the Consolidated Amended Fund Derivative Complaint. On September 15, 2006, the MDL Court granted the Invesco defendants' motion to dismiss the Amended Class Action Complaint for Violations of ERISA and dismissed such Complaint. Plaintiff appealed this ruling. On June 16, 2008, the Fourth Circuit Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings. IFG, Invesco Aim, IADI 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, among others, 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 security holders. IFG, Invesco Aim and IADI have advised the Fund that they are providing full cooperation with respect to these inquiries. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, Invesco Aim and/or related entities and individuals in the future. At the present time, management of Invesco Aim and the Fund are unable to estimate the impact, if any, that the outcome of the Pending Litigation and Regulatory Inquiries described above may have on Invesco Aim, IADI or the Fund. 22 AIM MULTI-SECTOR FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of AIM Counselor Series Trust 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 (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2008, 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, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PRICEWATERHOUSECOOPERS LLP October 20, 2008 Houston, Texas 23 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 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 example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2008, through August 31, 2008. 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 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. <Table> <Caption> - --------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2) (08/31/08) PERIOD(2) RATIO - --------------------------------------------------------------------------------------------------- A $1,000.00 $975.70 $6.06 $1,019.00 $6.19 1.22% - --------------------------------------------------------------------------------------------------- B 1,000.00 972.40 9.77 1,015.23 9.98 1.97 - --------------------------------------------------------------------------------------------------- C 1,000.00 972.30 9.77 1,015.23 9.98 1.97 - --------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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.

I'd like to take this opportunity to update you on recent market developments and provide some perspective and encouragement to [TAYLOR fellow long-term investors. PHOTO] MARKET OVERVIEW About a year ago or so, we saw warning signs of increasing economic ills -- a weakening housing market, rising inflation and slowing job growth, among others. Nonetheless, U.S. equity markets were performing Philip Taylor relatively well. But as the year progressed, the housing market deteriorated, energy prices rose, unemployment increased and the credit crunch grew more widespread. In response, the U.S. Federal Reserve cut short-term interest rate targets to stimulate economic growth and expand market liquidity.(1) Congress and the president worked together to enact an economic stimulus plan, one facet of which was to provide more than 112 million taxpayers with $92 billion in tax rebates.(2) Historically, actions such as these have stimulated economic growth. Unfortunately, other factors were simultaneously at work behind the scenes, and the market began to reveal the strain of those factors. HOW WE GOT HERE The market stresses we saw over the past year were the result of years of lax lending associated with the recent housing boom. Mortgage loans of questionable quality were bundled into hard-to-value securities that were sold to, and traded among, financial institutions. The value of those securities declined; more institutions sought to sell them and fewer institutions were willing to buy them. As a result, financial institutions' access to credit declined and the value of their holdings declined -- preventing normal trading among banks and other financial institutions. In October 2008, Congress enacted a plan, the Troubled Assets Relief Program, authorizing the U.S. Department of the Treasury to purchase up to $700 billion in troubled mortgage-related assets -- the largest and most direct effort to resolve a credit crisis in the last half century. INVESTING IN A VOLATILE MARKET Whether or not markets recover in the short term, the kind of volatility we've seen of late is a good reminder that in times of market uncertainty, it's wise to stay true to three timeless investing principles: o INVEST FOR THE LONG TERM. Short-term fluctuations have always been a reality of the markets. I urge you to stick to your investment plan and stay focused on your long-term goals. o DIVERSIFY. Although diversification doesn't eliminate the risk of loss or guarantee a profit, a careful selection of complementary asset classes may potentially cushion your portfolio against excessive volatility. o STAY FULLY INVESTED. Trying to time the market is a gamble, not an investment strategy. A sound investment strategy includes viewing market volatility as a matter of course, not a reason to panic. That leads me to a fourth principle we believe may be critical to your success: Work with a trusted financial advisor. An experienced advisor who knows your goals and situation can be your most valuable asset, particularly during times of market volatility. Your advisor can provide guidance and can monitor your investments to ensure they're on course. Recent market volatility has been disconcerting for everyone. Remember, however, that many of history's significant buying opportunities were the result of short-term economic crises that, in their time, were considered unprecedented. I believe current market volatility and uncertainty may represent a buying opportunity for patient, long-term investors. Invesco Aim's portfolio managers are working diligently on your behalf to capitalize on this situation. OUR NEW BRAND IDENTITY While market conditions are obviously at the top of everyone's mind, there are some significant changes I want to share with you: We have a new name and a new brand -- Invesco Aim. Our parent company, Invesco Ltd., is one of the world's largest and most diversified global investment managers with $450 billion in assets under management as of August 31, 2008. Invesco has 5,300 employees in 13 investment centers worldwide serving clients in 100 countries. This provides you: o Diversified investment strategies from distinct management teams around the globe. o A range of investment products to help you achieve your financial goals. o The peace of mind professional asset management and a diversified investment portfolio can provide. While our name may have changed, our commitment to putting shareholders first, helping clients achieve their investment goals and providing excellent customer service will never change. If you have questions about this report or your account, please contact one of our client service representatives at 800 959 4246. Thank you for your continued confidence, and we look forward to serving you. Sincerely, /S/ PHILIP TAYLOR Philip Taylor Senior Managing Director, Invesco Ltd.

Your Board of Trustees believes in the wisdom of a long-term perspective and consistent investment [CROCKETT discipline. We continue to put your interests first in the effort to improve investment performance, PHOTO] contain shareholder costs and uphold the highest ethical standards. We remain enthusiastic about the global reach and investment expertise that Invesco, a leading independent global investment management company, brings to the management of AIM Funds as the parent company of the advisors. The diverse investment strategies deployed throughout the worldwide network of Bruce Crockett Invesco investment centers has helped strengthen the management of many AIM Funds. The rebranding of the Funds' management company as Invesco Aim was followed by the launch of an upgraded, investor-friendly website (invescoaim.com); a new mountain logo using a Himalayan peak to symbolize stability, endurance, strength and longevity; and a new ad campaign. Emphasizing Invesco Aim's focus and investment quality, the ads will appear in financial publications such as Barron's and Investment News through the end of 2008. 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." We have recently completed another active proxy voting season during which we acted on your behalf to double the number of votes in favor of separating the roles of chairman and CEO at the companies whose shares your Funds hold. We also continued to support the movement for shareholders to have a bigger role in approving executive compensation, initiatives known as "say on pay." Like virtually all other mutual fund complexes, AIM Funds abstain from voting on social issues as a matter of policy, and I would be interested to hear your thoughts on this policy. As always, you are welcome to email your questions or comments to me at bruce@brucecrockett.com. The dialogue that has been established in this way has been instructive for your Board, and we want it to continue. Although the production schedule for Fund annual reports and prospectuses allows me to write these letters of general report and response just twice a year, please be assured that your comments are received, welcomed and heard in the interim. We look forward to hearing from you and to representing you. Sincerely, /S/ BRUCE L. CROCKETT Bruce L.

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 six separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. Prior to March 12, 2007, the Fund operated as AIM Select Real Estate Income Fund (the "Closed-End Fund"). The Closed-End Fund was reorganized as an open-end fund at which time the Fund became a new series portfolio of the Trust. The Closed-End Fund was reorganized as an open-end fund on March 12, 2007 (the "Reorganization Date") through the transfer of all its assets and liabilities to the Fund (the "Reorganization"). Prior to the Reorganization, the Closed-End Fund redeemed Preferred Shares in their entirety. As part of the Reorganization, the Closed-End Fund was restructured from a sole series of AIM Select Real Estate Income Fund to a new series portfolio of the Trust. Upon the closing of the Reorganization, holders of the Closed-End Fund Common Shares received Class A shares of the Fund. Information for the Common Shares of the Closed-End Fund, prior to the Reorganization is included with Class A shares throughout this report. The Fund currently offers four different classes of shares: Class A, Class B, Class C 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. Institutional Class shares are sold at net asset value. 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. 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 objectives are high current income and secondarily, capital appreciation. 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 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 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 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. 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 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. 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 may 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 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. 14 AIM SELECT REAL ESTATE INCOME FUND 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 as 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 recharacterizes distributions received from REIT investments based on information provided by the REIT into the following categories: ordinary income, long-term and short-term capital gains, and return of capital. If information is not available timely from the REIT, the recharacterization will be based on available information which may include the previous year's allocation. If new or additional information becomes available from the REIT at a later date, a recharacterization will be made in the following year. The Fund records as dividend income the amount recharacterized as ordinary income and as realized gain the amount recharacterized as capital gain in the Statement of Operations, and the amount recharacterized as return of capital in the Statement of Changes in Net Assets. These recharacterizations are reflected in the accompanying financial statements. 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 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 and paid quarterly and are recorded on ex-dividend date. 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. H. INDEMNIFICATIONS -- 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. The risk of material loss as a result of such indemnification claims is considered remote. 15 AIM SELECT REAL ESTATE INCOME FUND I. RISKS INVOLVED IN INVESTING IN THE FUND -- The Fund's investments are concentrated in a comparatively narrow segment of the economy. Consequently, the Fund may tend to be more volatile than other mutual funds, and the value of the Fund's investments may tend to rise and fall more rapidly. The Fund concentrates its assets in the real estate industry, an investment in the fund will be closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from economic, legal, cultural or technological developments. J. SECURITIES LENDING -- 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 by the securities lending provider. Such collateral will be cash or debt securities issued or guaranteed by the U.S. Government or any of its sponsored agencies. Cash collateral received in connection with these loans is invested in short-term money market instruments or affiliated money market funds and is shown as such on the Schedule of Investments. 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 any loss on the collateral invested. Dividends received on cash collateral investments for securities lending transactions, which are net of compensation to counterparties, is included in Dividends from affiliates on the Statement of Operations. The aggregate value of securities out on loan is shown as a footnote on the Statement of Assets and Liabilities, if any. K. TEMPORARY REDEMPTION FEES -- The Fund had a 2% redemption fee which expired in March 2008, that was retained by the Fund when Class A shares issued in connection with the Reorganization of the Closed-End Fund were redeemed within 12 months following the Reorganization Date. The redemption fee was recorded as an increase in shareholder capital and was allocated among the share classes based on the relative net assets of each class. 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: <Table> <Caption> AVERAGE NET ASSETS RATE - ------------------------------------------------------------------- First $250 million 0.75% - ------------------------------------------------------------------- Next $250 million 0.74% - ------------------------------------------------------------------- Next $500 million 0.73% - ------------------------------------------------------------------- Next $1.5 billion 0.72% - ------------------------------------------------------------------- Next $2.5 billion 0.71% - ------------------------------------------------------------------- Next $2.5 billion 0.70% - ------------------------------------------------------------------- Next $2.5 billion 0.69% - ------------------------------------------------------------------- Over $10 billion 0.68% ___________________________________________________________________ =================================================================== </Table> Under the terms of a new master sub-advisory agreement approved by shareholders of the Fund, effective May 1, 2008, 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). Previously, under the terms of a master sub-advisory agreement between the Advisor and Invesco Institutional (N.A.), Inc., the Advisor paid Invesco Institutional (N.A.), Inc. 40% of the amount paid by the Fund to the Advisor, net of any fee waivers and expense reimbursements. This agreement terminated on May 1, 2008. The Advisor has contractually agreed, through at least June 30, 2009, 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 (excluding investments of cash collateral from securities lending) in such affiliated money market funds. For the year ended August 31, 2008, the Advisor waived advisory fees of $7,037. At the request of the Trustees of the Trust, Invesco Ltd. ("Invesco") 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, 2008, Invesco reimbursed expenses of the Fund in the amount of $878. 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 year ended August 31, 2008, 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 16 AIM SELECT REAL ESTATE INCOME FUND limitations approved by the Trust's Board of Trustees. For the year ended August 31, 2008, expenses incurred under the agreement are shown in the Statement of Operations as transfer agent fees. 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 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 Plans, pays IADI 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. 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 year ended August 31, 2008, 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 year ended August 31, 2008, IADI advised the Fund that IADI retained $24,610 in front-end sales commissions from the sale of Class A shares and $0, $156 and $637 from Class A, Class B and Class C 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--EXPENSE OFFSET ARRANGEMENTS The expense offset arrangements are comprised of (i) transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions and (ii) custodian credits which result from periodic overnight cash balances at the custodian. For the year ended August 31, 2008, the Fund received credits from these arrangements, which resulted in the reduction of the Fund's total expenses of $11,115. NOTE 4--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 year ended August 31, 2008, the Fund paid legal fees of $2,822 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 5--CASH BALANCES 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. NOTE 6--DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF NET ASSETS DISTRIBUTIONS TO SHAREHOLDERS: The tax character of distributions paid during the year ended August 31, 2008, eight months ended August 31, 2007 and the year ended December 31, 2006 was as follows: <Table> <Caption> 2008 2007 2006 - ---------------------------------------------------------------------------------------------------------------- Ordinary income $10,440,892 $ 9,122,441 $ 42,317,025(a) - ---------------------------------------------------------------------------------------------------------------- Long-term capital gain 74,988,353 3,664,438 151,143,466(b) ================================================================================================================ Total distributions $85,429,245 $12,786,879 $193,460,491 ________________________________________________________________________________________________________________ ================================================================================================================ </Table> (a) Includes Preferred Shares ordinary income distributions of $1,756,638 for the year ended December 31, 2006. (b) Includes Preferred Shares long-term capital gain distributions of $6,274,173 for the year ended December 31, 2006. 17 AIM SELECT REAL ESTATE INCOME FUND TAX COMPONENTS OF NET ASSETS: As of August 31, 2008, the components of net assets on a tax basis were as follows: <Table> <Caption> 2008 - ------------------------------------------------------------------------------------------------ Undistributed ordinary income $ 578,907 - ------------------------------------------------------------------------------------------------ Net unrealized appreciation (depreciation) -- investments (12,757,237) - ------------------------------------------------------------------------------------------------ Temporary book/tax differences (81,663) - ------------------------------------------------------------------------------------------------ Post-October capital loss deferral (6,528,086) - ------------------------------------------------------------------------------------------------ Shares of beneficial interest 146,072,041 ================================================================================================ Total net assets $127,283,962 ________________________________________________________________________________________________ ================================================================================================ </Table> 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 wash sales. 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 benefits. The Fund does not have a capital loss carryforward at period-end. NOTE 7--INVESTMENT SECURITIES The aggregate amount of investment securities (other than short-term securities, U.S. Treasury obligations and money market funds, if any) purchased and sold by the Fund during the year ended August 31, 2008 was $109,722,960 and $176,901,515, respectively. Cost of investments on a tax basis includes the adjustments for financial reporting purposes as of the most recently completed Federal income tax reporting period end. <Table> <Caption> UNREALIZED APPRECIATION (DEPRECIATION) OF INVESTMENT SECURITIES ON A TAX BASIS - ------------------------------------------------------------------------------------------------ Aggregate unrealized appreciation of investment securities $ 6,908,417 - ------------------------------------------------------------------------------------------------ Aggregate unrealized (depreciation) of investment securities (19,665,654) ================================================================================================ Net unrealized appreciation (depreciation) of investment securities $(12,757,237) ________________________________________________________________________________________________ ================================================================================================ Cost of investments for tax purposes is $156,540,288. </Table> NOTE 8--RECLASSIFICATION OF PERMANENT DIFFERENCES Primarily as a result of differing book/tax treatment of expenses related to the plan of reorganization and distributions to shareholders on August 31, 2008, undistributed net investment income was increased by $1,584,188, undistributed net realized gain (loss) was decreased by $1,751,318 and shares of beneficial interest increased by $167,130. This reclassification had no effect on the net assets of the Fund. 18 AIM SELECT REAL ESTATE INCOME FUND NOTE 9--SHARE INFORMATION <Table> <Caption> CHANGES IN SHARES OUTSTANDING - ----------------------------------------------------------------------------------------------------------------------- YEAR ENDED EIGHT MONTHS ENDED YEAR ENDED AUGUST 31, 2008(a) AUGUST 31, 2007(b) DECEMBER 31, 2006 --------------------------- ----------------------------- ------------------------- SHARES AMOUNT SHARES AMOUNT SHARES AMOUNT - ----------------------------------------------------------------------------------------------------------------------- Sold: Class A 1,839,980 $ 16,558,591 141,022 $ 2,382,123 -- $ -- - ----------------------------------------------------------------------------------------------------------------------- Class B(c) 159,313 1,442,997 10,418 174,122 -- -- - ----------------------------------------------------------------------------------------------------------------------- Class C(c) 246,055 2,240,917 22,500 365,894 -- -- - ----------------------------------------------------------------------------------------------------------------------- Institutional Class(c) 1,546,029 14,211,127 581 10,017 -- -- ======================================================================================================================= Issued as reinvestment of dividends: Class A 4,159,275 37,122,833 212,635 3,618,000 -- -- - ----------------------------------------------------------------------------------------------------------------------- Class B(c) 11,708 103,040 55 926 -- -- - ----------------------------------------------------------------------------------------------------------------------- Class C(c) 16,374 144,890 35 588 -- -- - ----------------------------------------------------------------------------------------------------------------------- Institutional Class(c) 19,351 169,747 10 172 -- -- ======================================================================================================================= Automatic conversion of Class B shares to Class A shares: Class A 6,502 54,878 1 22 -- -- - ----------------------------------------------------------------------------------------------------------------------- Class B (6,516) (54,878) (1) (22) -- -- ======================================================================================================================= Reacquired:(d) Class A (6,467,883) (66,804,166) (25,696,786) (435,827,235) (827,300)(e) (13,033,473)(e) - ----------------------------------------------------------------------------------------------------------------------- Class B(c) (40,000) (338,457) (474) (6,892) -- -- - ----------------------------------------------------------------------------------------------------------------------- Class C(c) (53,711) (510,736) (620) (9,170) -- -- - ----------------------------------------------------------------------------------------------------------------------- Institutional Class(c) (52,039) (429,611) -- 239 -- -- ======================================================================================================================= 1,384,438 $ 3,911,172 (25,310,624) $(429,291,216) (827,300)(e) $(13,033,473)(e) _______________________________________________________________________________________________________________________ ======================================================================================================================= </Table> (a) There are entities that are record owners of more than 5% of the outstanding shares of the Fund and in the aggregate own 22% of the outstanding shares of the Fund. IADI has an agreement with these entities to sell Fund shares. The Fund, Invesco Aim and/or Invesco Aim affiliates may make payments to these entities, which are considered to be related to the Fund, for providing services to the Fund, Invesco Aim and/or Invesco Aim affiliates including but not limited to services such as securities brokerage, distribution, third party record keeping and account servicing. The Trust has no knowledge as to whether all or any portion of the shares owned of record by these entities are also owned beneficially. In addition, 10% of the outstanding shares of the Fund are owned by affiliated mutual funds. Affiliated mutual funds are other mutual funds that are also advised by Invesco Aim. (b) Upon the Reorganization as an open-end fund on March 12, 2007, holders of the Closed-End Fund Common Shares received 39,108,196 Class A shares of the Fund with an aggregate net assets value of $680,052,002 in connection with such reorganization, which was equal to the number of Closed-End Fund Common Shares they owned and the aggregate net assets value prior to the Reorganization. The net asset value of the Fund's Class A shares received in connection with the Reorganization immediately after the Reorganization was the same as the net asset value of Closed-End Fund Common Shares immediately prior to the Reorganization.

(a) Calculated using average shares outstanding. 20 AIM SELECT REAL ESTATE INCOME FUND NOTE 10--FINANCIAL HIGHLIGHTS--(CONTINUED) (b) As a result of changes in accounting principles generally accepted in the United States of America, the Closed-End Fund reclassified periodic payments made under interest rate swap agreements, previously included within interest expense as a component of realized gain (loss) in the Statement of Operations. The effect of this reclassification was to increase the net investment income ratio by 0.67%, decrease the expense ratio by 0.67% and increase net investment income per share by $0.10 for the year ended December 31, 2003. (c) Based on average number of common shares outstanding of Closed-End Fund. (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.

(e) Includes the impact of the temporary 2% redemption fee which was effective March 12, 2007 through March 11, 2008. (f) Net asset value return includes adjustments in accordance with accounting principles generally accepted in the United States of America and measures the changes in common shares' value of Closed-End over the period indicated, taking into account dividends as reinvested. Market value return is computed based upon the New York Stock Exchange market price of the Closed-End Fund's common shares and excludes the effects of brokerage commissions. Dividends and distributions, if any, are assumed for purposes of this calculation, to be reinvested at prices obtained under the Closed- End Fund's dividend reinvestment plan.

NOTE 11--LEGAL PROCEEDINGS Terms used in the Legal Proceedings Note are defined terms solely for the purpose of this note. PENDING LITIGATION AND REGULATORY INQUIRIES 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 Invesco Aim and IADI (Order No. 05-1318). The WVASC makes findings of fact that Invesco Aim and IADI entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and IADI violated the West Virginia securities laws. The WVASC orders Invesco Aim and IADI to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, Invesco Funds Group, Inc. ("IFG"), Invesco Aim, IADI 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; and - that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), negligence, breach of fiduciary duty and/or breach of contract. These lawsuits seek 22 AIM SELECT REAL ESTATE INCOME FUND NOTE 11--LEGAL PROCEEDINGS--(CONTINUED) 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. The case pending in Illinois State Court regarding fair value pricing was dismissed with prejudice on May 6, 2008. All lawsuits based on allegations of market timing, late trading and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court"). Pursuant to an Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties: (i) a Consolidated Amended Class Action Complaint purportedly brought on behalf of shareholders of the AIM Funds; (ii) a Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint for Violations of ERISA purportedly brought on behalf of participants in the Invesco 401(k) plan. Based on orders issued by the MDL Court, all claims asserted against the AIM Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the Consolidated Amended Fund Derivative Complaint. On September 15, 2006, the MDL Court granted the Invesco defendants' motion to dismiss the Amended Class Action Complaint for Violations of ERISA and dismissed such Complaint. Plaintiff appealed this ruling. On June 16, 2008, the Fourth Circuit Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings. IFG, Invesco Aim, IADI 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, among others, 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 security holders. IFG, Invesco Aim and IADI have advised the Fund that they are providing full cooperation with respect to these inquiries. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, Invesco Aim and/or related entities and individuals in the future. At the present time, management of Invesco Aim and the Fund are unable to estimate the impact, if any, that the outcome of the Pending Litigation and Regulatory Inquiries described above may have on Invesco Aim, IADI or the Fund. 23 AIM SELECT REAL ESTATE INCOME FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of AIM Select Real Estate Income 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 Select Real Estate Income Fund (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2008, the results of its operations for the year then ended, the changes in its net assets and the financial highlights for each of the periods then 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, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PRICEWATERHOUSECOOPERS LLP October 20, 2008 Houston, Texas 24 AIM SELECT REAL ESTATE INCOME 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 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 example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2008, through August 31, 2008. 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 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. <Table> <Caption> - --------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2) (08/31/08) PERIOD(2) RATIO - --------------------------------------------------------------------------------------------------- A $1,000.00 $986.00 $ 7.14 $1,017.95 $ 7.25 1.43% - --------------------------------------------------------------------------------------------------- B 1,000.00 982.10 10.86 1,014.18 11.04 2.18 - --------------------------------------------------------------------------------------------------- C 1,000.00 982.20 10.86 1,014.18 11.04 2.18 - --------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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.

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, 2008, through August 31, 2008. 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.

I'd like to take this opportunity to update you on recent market developments and provide some perspective and encouragement to [TAYLOR fellow long-term investors. PHOTO] MARKET OVERVIEW About a year ago or so, we saw warning signs of increasing economic ills -- a weakening housing market, rising inflation and slowing job growth, among others. Nonetheless, U.S. equity markets were performing Philip Taylor relatively well. But as the year progressed, the housing market deteriorated, energy prices rose, unemployment increased and the credit crunch grew more widespread. In response, the U.S. Federal Reserve cut short-term interest rate targets to stimulate economic growth and expand market liquidity.(1) Congress and the president worked together to enact an economic stimulus plan, one facet of which was to provide more than 112 million taxpayers with $92 billion in tax rebates.(2) Historically, actions such as these have stimulated economic growth. Unfortunately, other factors were simultaneously at work behind the scenes, and the market began to reveal the strain of those factors. HOW WE GOT HERE The market stresses we saw over the past year were the result of years of lax lending associated with the recent housing boom. Mortgage loans of questionable quality were bundled into hard-to-value securities that were sold to, and traded among, financial institutions. The value of those securities declined; more institutions sought to sell them and fewer institutions were willing to buy them. As a result, financial institutions' access to credit declined and the value of their holdings declined -- preventing normal trading among banks and other financial institutions. In October 2008, Congress enacted a plan, the Troubled Assets Relief Program, authorizing the U.S. Department of the Treasury to purchase up to $700 billion in troubled mortgage-related assets -- the largest and most direct effort to resolve a credit crisis in the last half century. INVESTING IN A VOLATILE MARKET Whether or not markets recover in the short term, the kind of volatility we've seen of late is a good reminder that in times of market uncertainty, it's wise to stay true to three timeless investing principles: o INVEST FOR THE LONG TERM. Short-term fluctuations have always been a reality of the markets. I urge you to stick to your investment plan and stay focused on your long-term goals. o DIVERSIFY. Although diversification doesn't eliminate the risk of loss or guarantee a profit, a careful selection of complementary asset classes may potentially cushion your portfolio against excessive volatility. o STAY FULLY INVESTED. Trying to time the market is a gamble, not an investment strategy. A sound investment strategy includes viewing market volatility as a matter of course, not a reason to panic. That leads me to a fourth principle we believe may be critical to your success: Work with a trusted financial advisor. An experienced advisor who knows your goals and situation can be your most valuable asset, particularly during times of market volatility. Your advisor can provide guidance and can monitor your investments to ensure they're on course. Recent market volatility has been disconcerting for everyone. Remember, however, that many of history's significant buying opportunities were the result of short-term economic crises that, in their time, were considered unprecedented. I believe current market volatility and uncertainty may represent a buying opportunity for patient, long-term investors. Invesco Aim's portfolio managers are working diligently on your behalf to capitalize on this situation. OUR NEW BRAND IDENTITY While market conditions are obviously at the top of everyone's mind, there are some significant changes I want to share with you: We have a new name and a new brand -- Invesco Aim. Our parent company, Invesco Ltd., is one of the world's largest and most diversified global investment managers with $450 billion in assets under management as of August 31, 2008. Invesco has 5,300 employees in 13 investment centers worldwide serving clients in 100 countries. This provides you: o Diversified investment strategies from distinct management teams around the globe. o A range of investment products to help you achieve your financial goals. o The peace of mind professional asset management and a diversified investment portfolio can provide. While our name may have changed, our commitment to putting shareholders first, helping clients achieve their investment goals and providing excellent customer service will never change. If you have questions about this report or your account, please contact one of our client service representatives at 800 959 4246. Thank you for your continued confidence, and we look forward to serving you. Sincerely, /S/ PHILIP TAYLOR Philip Taylor Senior Managing Director, Invesco Ltd. CEO, Invesco Aim October 20, 2008 (1) U.S. Federal Reserve Board; 2 U.S. Department of the Treasury 2 AIM STRUCTURED CORE FUND Dear Fellow Shareholders: As I write this letter, turbulent financial markets are causing considerable investor anxiety, reminding us again that markets are cyclical and the correction of excess is often painful, at least in the short term. [CROCKETT Your Board of Trustees believes in the wisdom of a long-term perspective and consistent investment PHOTO] discipline. We continue to put your interests first in the effort to improve investment performance, contain shareholder costs and uphold the highest ethical standards. We remain enthusiastic about the global reach and investment expertise that Invesco, a leading independent global investment management company, brings to the management of AIM Funds as the parent Bruce Crockett company of the advisors. The diverse investment strategies deployed throughout the worldwide network of Invesco investment centers has helped strengthen the management of many AIM Funds. The rebranding of the Funds' management company as Invesco Aim was followed by the launch of an upgraded, investor-friendly website (invescoaim.com); a new mountain logo using a Himalayan peak to symbolize stability, endurance, strength and longevity; and a new ad campaign. Emphasizing Invesco Aim's focus and investment quality, the ads will appear in financial publications such as Barron's and Investment News through the end of 2008. 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." We have recently completed another active proxy voting season during which we acted on your behalf to double the number of votes in favor of separating the roles of chairman and CEO at the companies whose shares your Funds hold. We also continued to support the movement for shareholders to have a bigger role in approving executive compensation, initiatives known as "say on pay." Like virtually all other mutual fund complexes, AIM Funds abstain from voting on social issues as a matter of policy, and I would be interested to hear your thoughts on this policy. As always, you are welcome to email your questions or comments to me at bruce@brucecrockett.com. The dialogue that has been established in this way has been instructive for your Board, and we want it to continue. Although the production schedule for Fund annual reports and prospectuses allows me to write these letters of general report and response just twice a year, please be assured that your comments are received, welcomed and heard in the interim. We look forward to hearing from you and to representing you. Sincerely, /S/ BRUCE L. CROCKETT Bruce L.

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 six separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently consists of six different classes of shares: Class A, Class B, Class C, Class R, Investor Class and Institutional Class. Investor Class shares of the Fund are offered only to certain grandfathered investors. 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 shares, Investor Class shares 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. 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 long-term growth of capital. 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 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 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 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. 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. 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 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. 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 may 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 and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Securities for which market quotations are not readily available or are 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. 15 AIM STRUCTURED CORE FUND 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. The Fund may periodically participate in litigation related to Fund investments. As such, the Fund may receive proceeds from litigation settlements. Any proceeds as 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 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, 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 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 and 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. H. INDEMNIFICATIONS -- 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. The risk of material loss as a result of such indemnification claims is considered remote. I. FUTURES CONTRACTS -- The Fund may purchase or sell futures contracts. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities as collateral for the account of the broker (the Fund's agent in acquiring the futures position). During the period the futures contracts are open, changes in the value of the contracts are recognized as unrealized gains or losses by recalculating the value of the contracts on a daily basis. Variation margin payments are received or made depending upon whether unrealized gains or losses are incurred. When the contracts are closed, the Fund recognizes a realized gain or loss equal to the difference between the proceeds from, or cost of, the closing transaction and the Fund's basis in the contract. 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. Risks may exceed amounts recognized in the Statement of Assets and Liabilities. J. 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. 16 AIM STRUCTURED CORE FUND 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: <Table> <Caption> AVERAGE NET ASSETS RATE - ------------------------------------------------------------------- First $250 million 0.60% - ------------------------------------------------------------------- Next $250 million 0.575% - ------------------------------------------------------------------- Next $500 million 0.55% - ------------------------------------------------------------------- Next $1.5 billion 0.525% - ------------------------------------------------------------------- Next $2.5 billion 0.50% - ------------------------------------------------------------------- Next $2.5 billion 0.475% - ------------------------------------------------------------------- Next $2.5 billion 0.45% - ------------------------------------------------------------------- Over $10 billion 0.425% ___________________________________________________________________ =================================================================== </Table> Under the terms of a new master sub-advisory agreement approved by shareholders of the Fund on March 28, 2008, effective May 1, 2008, 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). Previously, under the terms of a master sub-advisory agreement between the Advisor and Invesco Institutional (N.A.), Inc., the Advisor paid Invesco Institutional (N.A.), Inc. 40% of the amount of the Advisor's compensation on the sub-advised assets. This agreement was terminated on May 1, 2008. Effective April 28, 2008, 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, Investor and Institutional Class shares to 0.60%, 1.35%, 1.35%, 0.85%, 0.60% and 0.35% of average daily net assets, respectively, through at least June 30, 2009. Prior to April 28, 2008, the Advisor had 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 and Institutional Class shares to 1.00%, 1.75%, 1.75%, 1.25% and 0.75% of average daily net assets. 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; (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. These credits are used to pay certain expenses incurred by the Fund. Further, the Advisor has contractually agreed, through at least June 30, 2009, 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 year ended August 31, 2008, the Advisor waived advisory fees and reimbursed Fund expenses of $407,200 and reimbursed class level expenses of $2,165, $1,108, $1,784, $939, $70,196 and $4,634 for Class A, Class B, Class C, Class R, Investor Class and Institutional Class shares, respectively. At the request of the Trustees of the Trust, Invesco 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, 2008, Invesco reimbursed expenses of the Fund in the amount of $23. 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 year ended August 31, 2008, 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 year ended August 31, 2008, expenses incurred under the agreement are shown in the Statement of Operations as transfer agent fees. 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, Investor Class 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, Class R and Investor Class 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, 0.50% of the average daily net assets of Class R shares and 0.25% of the average daily net assets of Investor Class 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 17 AIM STRUCTURED CORE FUND 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 year ended August 31, 2008, 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 year ended August 31, 2008, IADI advised the Fund that IADI retained $853 in front-end sales commissions from the sale of Class A shares and $0, $398, $9,353 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--EXPENSE OFFSET ARRANGEMENTS The expense offset arrangements are comprised of (i) transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions and (ii) custodian credits which result from periodic overnight cash balances at the custodian. For the year ended August 31, 2008, the Fund received credits from this arrangement, which resulted in the reduction of the Fund's total expenses of $1,059. NOTE 4--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 year ended August 31, 2008, the Fund paid legal fees of $2,493 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 5--CASH BALANCES 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.

The Fund's net unrealized appreciation difference is attributable primarily to wash sales and futures contracts. 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 benefits. The Fund does not have a capital loss carryforward at period-end. NOTE 8--INVESTMENT SECURITIES The aggregate amount of investment securities (other than short-term securities, U.S. Treasury obligations and money market funds, if any) purchased and sold by the Fund during the year ended August 31, 2008 was $198,248,611 and $68,105,664, respectively. Cost of investments on a tax basis includes the adjustments for financial reporting purposes as of the most recently completed Federal income tax reporting period end. <Table> <Caption> UNREALIZED APPRECIATION (DEPRECIATION) OF INVESTMENT SECURITIES ON A TAX BASIS - ------------------------------------------------------------------------------------------------ Aggregate unrealized appreciation of investment securities $ 10,452,509 - ------------------------------------------------------------------------------------------------ Aggregate unrealized (depreciation) of investment securities (10,024,496) ================================================================================================ Net unrealized appreciation of investment securities $ 428,013 ________________________________________________________________________________________________ ================================================================================================ Cost of investments for tax purposes is $166,998,148. </Table> NOTE 9--RECLASSIFICATION OF PERMANENT DIFFERENCES Primarily as a result of differing book/tax treatment of expenses related to the plan of reorganization on August 31, 2008, undistributed net investment income was increased by $1,116, undistributed net realized gains was increased by $19,854 and shares of beneficial interest decreased by $20,970. Further, as a result of tax deferrals acquired in the reorganization of AIM S&P 500 Index Fund, undistributed net investment income was decreased by $11,169, undistributed net realized gain was decreased by $7,176,333 and shares of beneficial interest increased by $7,187,502. These reclassifications had no effect on the net assets of the Fund. 19 AIM STRUCTURED CORE FUND NOTE 10--SHARE INFORMATION <Table> <Caption> CHANGES IN SHARES OUTSTANDING - --------------------------------------------------------------------------------------------------------------------- YEAR ENDED AUGUST 31, ------------------------------------------------------ 2008(a) 2007 --------------------------- ---------------------- SHARES AMOUNT SHARES AMOUNT - --------------------------------------------------------------------------------------------------------------------- Sold: Class A 52,645 $ 550,487 44,275 $ 491,285 - --------------------------------------------------------------------------------------------------------------------- Class B 10,713 113,741 16,451 183,040 - --------------------------------------------------------------------------------------------------------------------- Class C 100,723 1,010,754 32,644 369,797 - --------------------------------------------------------------------------------------------------------------------- Class R 5,587 57,004 361 4,008 - --------------------------------------------------------------------------------------------------------------------- Investor Class(b) 878,241 9,098,926 -- -- - --------------------------------------------------------------------------------------------------------------------- Institutional Class 1,946,816 21,051,375 22,949 258,872 ===================================================================================================================== Issued as reinvestment of dividends: Class A 931 10,620 1,872 20,605 - --------------------------------------------------------------------------------------------------------------------- Class B 338 3,837 656 7,234 - --------------------------------------------------------------------------------------------------------------------- Class C 424 4,818 618 6,815 - --------------------------------------------------------------------------------------------------------------------- Class R 285 3,252 880 9,690 - --------------------------------------------------------------------------------------------------------------------- Investor Class(b) -- -- -- -- - --------------------------------------------------------------------------------------------------------------------- Institutional Class 9,141 104,300 1,063 11,700 ===================================================================================================================== Issued in connection with acquisitions:(c) Investor Class 17,521,866 188,037,074 -- -- - --------------------------------------------------------------------------------------------------------------------- Institutional Class 1,777,178 19,072,533 -- -- ===================================================================================================================== Automatic conversion of Class B shares to Class A shares: Class A 4,681 51,224 223 2,548 - --------------------------------------------------------------------------------------------------------------------- Class B (4,713) (51,224) (223) (2,548) ===================================================================================================================== Reacquired: Class A (98,908) (1,013,056) (6,193) (68,381) - --------------------------------------------------------------------------------------------------------------------- Class B (65,478) (643,462) (3,915) (44,203) - --------------------------------------------------------------------------------------------------------------------- Class C (169,375) (1,722,430) (1,122) (12,223) - --------------------------------------------------------------------------------------------------------------------- Class R (61,725) (604,374) -- -- - --------------------------------------------------------------------------------------------------------------------- Investor Class(b) (4,572,466) (47,668,786) -- -- - --------------------------------------------------------------------------------------------------------------------- Institutional Class (851,641) (8,666,960) -- -- ===================================================================================================================== 16,485,263 $178,799,653 110,539 $1,238,239 _____________________________________________________________________________________________________________________ ===================================================================================================================== </Table> (a) There are entities that are record owners of more than 5% of the outstanding shares of the Fund and in the aggregate own 23% of the outstanding shares of the Fund. IADI has an agreement with these entities to sell Fund shares. The Fund, Invesco Aim and/or Invesco Aim affiliates may make payments to these entities, which are considered to be related to the Fund, for providing services to the Fund, Invesco Aim and/or Invesco Aim affiliates including but not limited to services such as securities brokerage, distribution, third party record keeping and account servicing. The Trust has no knowledge as to whether all or any portion of the shares owned of record by these entities are also owned beneficially. (b) Investor Class shares commenced on April 25, 2008. (c) As of the open of business on April 28, 2008, the Fund acquired all the net assets of AIM S&P 500 Index Fund pursuant to a plan of reorganization approved by the Trustees of the Fund on October 30, 2007 and by the shareholders of AIM S&P 500 Index Fund on March 28, 2008. The acquisition was accomplished by a tax-free exchange of 19,299,044 shares of the Fund for 14,941,286 shares outstanding of AIM S&P 500 Index Fund as of the close of business on April 25, 2008. Each class of AIM S&P 500 Index Fund was exchanged for the like class of shares of the Fund based on the relative net asset value of AIM S&P 500 Index Fund to the net asset value of the Fund on the close of business, April 25, 2008. AIM S&P 500 Index Fund's net assets at that date of $207,109,606 including $44,541,884 of unrealized appreciation, was combined with those of the Fund. The net assets of the Fund immediately before the acquisition were $15,694,957. The net assets of the Fund immediately following the acquisition were $222,804,563. NOTE 11--NEW ACCOUNTING STANDARD In March 2008, the Financial Accounting Standards Board (FASB) issued 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. It is effective for financial statements issued for fiscal years beginning after November 15, 2008. Management is currently in the process of determining the impact of the standard on the Fund's disclosures in the financial statements. 20 AIM STRUCTURED CORE FUND NOTE 12--FINANCIAL HIGHLIGHTS The following schedule presents financial highlights for a share of the Fund outstanding throughout the periods indicated. <Table> <Caption> INCOME (LOSS) FROM INVESTMENT OPERATIONS ------------------------------------- NET GAINS DISTRIBUTIONS (LOSSES) ---------------------------------------- NET ASSET NET ON SECURITIES DIVIDENDS DISTRIBUTIONS VALUE, INVESTMENT (BOTH TOTAL FROM FROM NET FROM NET NET ASSET BEGINNING INCOME REALIZED AND INVESTMENT INVESTMENT REALIZED TOTAL VALUE, END OF PERIOD (LOSS) UNREALIZED) OPERATIONS INCOME GAINS DISTRIBUTIONS OF PERIOD -

PENDING LITIGATION AND REGULATORY INQUIRIES 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 Invesco Aim and IADI (Order No. 05- 1318). The WVASC makes findings of fact that Invesco Aim and IADI entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and IADI violated the West Virginia securities laws. The WVASC orders Invesco Aim and IADI to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, Invesco Funds Group, Inc. ("IFG"), Invesco Aim, IADI 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; and - that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and the Employee Retirement Income Security Act of 1974, as amended ("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. The case pending in Illinois State Court regarding fair value pricing was dismissed with prejudice on May 6, 2008. All lawsuits based on allegations of market timing, late trading and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court"). Pursuant to an Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties: (i) a Consolidated Amended Class Action Complaint purportedly brought on behalf of shareholders of the AIM Funds; (ii) a Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint for Violations of ERISA purportedly brought on behalf of participants in the Invesco 401(k) plan. Based on orders issued by the MDL Court, all claims asserted against the AIM Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the Consolidated Amended Fund Derivative Complaint. On September 15, 2006, the MDL Court granted the Invesco defendants' motion to dismiss the Amended Class Action Complaint for Violations of ERISA and dismissed such Complaint. Plaintiff appealed this ruling. On June 16, 2008, the Fourth Circuit Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings. IFG, Invesco Aim, IADI 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, among others, 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 security holders. IFG, Invesco Aim and IADI have advised the Fund that they are providing full cooperation with respect to these inquiries. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, Invesco Aim and/or related entities and individuals in the future. At the present time, management of Invesco Aim and the Fund are unable to estimate the impact, if any, that the outcome of the Pending Litigation and Regulatory Inquiries described above may have on Invesco Aim, IADI or the Fund. 22 AIM STRUCTURED CORE FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of AIM Counselor Series Trust and Shareholders of AIM Structured Core 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 Structured Core Fund (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2008, 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, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PRICEWATERHOUSECOOPERS LLP October 20, 2008 Houston, Texas 23 AIM STRUCTURED CORE 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 or 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. With the exception of the actual ending account value and expenses of the Investor Class Shares, 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, 2008, through August 31, 2008. The actual ending account and expenses of the Investor Class shares in the below example are based on an investment of $1,000 invested as of close of business April 25, 2008 (the date the share class commenced operations) and held through August 31, 2008. 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 (as of close of business April 25, 2008 through August 31, 2008 for the Investor Class Shares). Because the actual ending account value and expense information in the example is not based upon a six month period for the Investor Class shares, 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 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. <Table> <Caption> - --------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2,4) (08/31/08) PERIOD(2,5) RATIO(3) - --------------------------------------------------------------------------------------------------- A $1,000.00 $984.10 $3.24 $1,021.87 $3.30 0.65% - --------------------------------------------------------------------------------------------------- B 1,000.00 980.00 6.97 1,018.10 7.10 1.40 - --------------------------------------------------------------------------------------------------- C 1,000.00 980.00 6.97 1,018.10 7.10 1.40 - --------------------------------------------------------------------------------------------------- R 1,000.00 982.10 4.48 1,020.61 4.57 0.90 - --------------------------------------------------------------------------------------------------- Investor(1) 1,000.00 984.10 2.10 1,022.12 3.05 0.60 - --------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008 (as of close of business April 25, 2008 through August 31, 2008 for the Investor Class shares), 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 184/366 to reflect the most recent fiscal half year. For the Investor Class shares actual expenses are equal to the annualized expense ratio indicated above multiplied by the average account value over the period, multiplied by 129 (as of close of business April 25, 2008, through August 31, 2008)/366. Because the Investor 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) Effective on April 28, 2008, the advisor contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses of Class A, Class B, Class C, Class R and Investor Class shares to 0.60%, 1.35%, 1.35%, 0.85% and 0.60% of average daily net assets, respectively. The annualized expense ratios restated as if this agreement had been in effect throughout the entire most recent fiscal half year are 0.60%, 1.35%, 1.35%, 0.85% and 0.60% for the Class A, Class B, Class C, Class R and Investor Class shares, respectively. 24 AIM STRUCTURED CORE FUND (4) The actual expenses paid restated as if the changes discussed above had been in effect throughout the entire most recent fiscal half year are $2.99, $6.72, $6.72, $4.23 and $2.10 for the Class A, Class B, Class C, Class R and Investor Class shares, respectively. (5) Hypothetical expenses are equal to the annualized expense ratio indicated above multiplied by the average account value over the period, multiplied by 184/366 to reflect a one-half year period. The hypothetical ending account value and expenses may be used to compare ongoing costs of investing in Investor Class shares of the Fund and other funds because such data is based on a full six month period. The hypothetical expenses paid restated as if the changes discussed above in footnote 3 had been in effect throughout the entire most recent fiscal half year are $3.05, $6.85, $ $6.85, $4.32 and $3.05 for the Class A, Class B, Class C, Class R and Investor Class shares, respectively. 25 AIM STRUCTURED CORE FUND Supplement to Annual Report dated 8/31/08 AIM STRUCTURED CORE FUND INSTITUTIONAL CLASS SHARES The following information has been prepared to provide Institutional Class shareholders with a performance overview specific to their holdings.

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, 2008, through August 31, 2008. 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 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. <Table> <Caption> - ------------------------------------------------------------------------------------------------ HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2,3) (08/31/08) PERIOD(2,4) RATIO(2) - ------------------------------------------------------------------------------------------------ Institutional $1,000.00 $986.10 $1.99 $1,023.13 $2.03 0.40% - ------------------------------------------------------------------------------------------------ </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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.

PHOTO] MARKET OVERVIEW Philip Taylor About a year ago or so, we saw warning signs of increasing economic ills -- a weakening housing market, rising inflation and slowing job growth, among others. Nonetheless, U.S. equity markets were performing relatively well. But as the year progressed, the housing market deteriorated, energy prices rose, unemployment increased and the credit crunch grew more widespread. In response, the U.S. Federal Reserve cut short-term interest rate targets to stimulate economic growth and expand market liquidity.(1) Congress and the president worked together to enact an economic stimulus plan, one facet of which was to provide more than 112 million taxpayers with $92 billion in tax rebates.(2) Historically, actions such as these have stimulated economic growth. Unfortunately, other factors were simultaneously at work behind the scenes, and the market began to reveal the strain of those factors. HOW WE GOT HERE The market stresses we saw over the past year were the result of years of lax lending associated with the recent housing boom. Mortgage loans of questionable quality were bundled into hard-to-value securities that were sold to, and traded among, financial institutions. The value of those securities declined; more institutions sought to sell them and fewer institutions were willing to buy them. As a result, financial institutions' access to credit declined and the value of their holdings declined -- preventing normal trading among banks and other financial institutions. In October 2008, Congress enacted a plan, the Troubled Assets Relief Program, authorizing the U.S. Department of the Treasury to purchase up to $700 billion in troubled mortgage-related assets -- the largest and most direct effort to resolve a credit crisis in the last half century. INVESTING IN A VOLATILE MARKET Whether or not markets recover in the short term, the kind of volatility we've seen of late is a good reminder that in times of market uncertainty, it's wise to stay true to three timeless investing principles: o INVEST FOR THE LONG TERM. Short-term fluctuations have always been a reality of the markets. I urge you to stick to your investment plan and stay focused on your long-term goals. o DIVERSIFY. Although diversification doesn't eliminate the risk of loss or guarantee a profit, a careful selection of complementary asset classes may potentially cushion your portfolio against excessive volatility. o STAY FULLY INVESTED. Trying to time the market is a gamble, not an investment strategy. A sound investment strategy includes viewing market volatility as a matter of course, not a reason to panic. That leads me to a fourth principle we believe may be critical to your success: Work with a trusted financial advisor. An experienced advisor who knows your goals and situation can be your most valuable asset, particularly during times of market volatility. Your advisor can provide guidance and can monitor your investments to ensure they're on course. Recent market volatility has been disconcerting for everyone. Remember, however, that many of history's significant buying opportunities were the result of short-term economic crises that, in their time, were considered unprecedented. I believe current market volatility and uncertainty may represent a buying opportunity for patient, long-term investors. Invesco Aim's portfolio managers are working diligently on your behalf to capitalize on this situation. OUR NEW BRAND IDENTITY While market conditions are obviously at the top of everyone's mind, there are some significant changes I want to share with you: We have a new name and a new brand -- Invesco Aim. Our parent company, Invesco Ltd., is one of the world's largest and most diversified global investment managers with $450 billion in assets under management as of August 31, 2008. Invesco has 5,300 employees in 13 investment centers worldwide serving clients in 100 countries. This provides you: o Diversified investment strategies from distinct management teams around the globe. o A range of investment products to help you achieve your financial goals. o The peace of mind professional asset management and a diversified investment portfolio can provide. While our name may have changed, our commitment to putting shareholders first, helping clients achieve their investment goals and providing excellent customer service will never change. If you have questions about this report or your account, please contact one of our client service representatives at 800 959 4246. Thank you for your continued confidence, and we look forward to serving you. Sincerely, /S/ PHILIP TAYLOR Philip Taylor Senior Managing Director, Invesco Ltd. CEO, Invesco Aim October 20, 2008 (1) U.S. Federal Reserve Board; (2) U.S. Department of the Treasury 2 AIM STRUCTURED GROWTH FUND Dear Fellow Shareholders: As I write this letter, turbulent financial markets are causing considerable investor anxiety, reminding us again that markets are cyclical and the correction of excess is often painful, at least in the short term. [CROCKETT Your Board of Trustees believes in the wisdom of a long-term perspective and consistent investment PHOTO] discipline. We continue to put your interests first in the effort to improve investment performance, contain shareholder costs and uphold the highest ethical standards. Bruce Crockett We remain enthusiastic about the global reach and investment expertise that Invesco, a leading independent global investment management company, brings to the management of AIM Funds as the parent company of the advisors. The diverse investment strategies deployed throughout the worldwide network of Invesco investment centers has helped strengthen the management of many AIM Funds. The rebranding of the Funds' management company as Invesco Aim was followed by the launch of an upgraded, investor-friendly website (invescoaim.com); a new mountain logo using a Himalayan peak to symbolize stability, endurance, strength and longevity; and a new ad campaign. Emphasizing Invesco Aim's focus and investment quality, the ads will appear in financial publications such as Barron's and Investment News through the end of 2008. 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." We have recently completed another active proxy voting season during which we acted on your behalf to double the number of votes in favor of separating the roles of chairman and CEO at the companies whose shares your Funds hold. We also continued to support the movement for shareholders to have a bigger role in approving executive compensation, initiatives known as "say on pay." Like virtually all other mutual fund complexes, AIM Funds abstain from voting on social issues as a matter of policy, and I would be interested to hear your thoughts on this policy. As always, you are welcome to email your questions or comments to me at bruce@brucecrockett.com. The dialogue that has been established in this way has been instructive for your Board, and we want it to continue. Although the production schedule for Fund annual reports and prospectuses allows me to write these letters of general report and response just twice a year, please be assured that your comments are received, welcomed and heard in the interim. We look forward to hearing from you and to representing you. Sincerely, /S/ BRUCE L. CROCKETT Bruce L.

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 six separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently offers five different classes of shares: Class A, Class B, Class C, Class R 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 shares 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. 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 long-term growth of capital. 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 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 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 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. 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 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. 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 may 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 and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Securities for which market quotations are not readily available or are 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. Dividend income is recorded on the ex-dividend date. Bond premiums and discounts are amortized and/or accreted for financial reporting purposes. 14 AIM STRUCTURED GROWTH FUND The Fund may periodically participate in litigation related to Fund investments. As such, the Fund may receive proceeds from litigation settlements. Any proceeds as 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 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, 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 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 and 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. H. INDEMNIFICATIONS -- 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. The risk of material loss as a result of such indemnification claims is considered remote. I. SECURITIES LENDING -- 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 by the securities lending provider. Such collateral will be cash or debt securities issued or guaranteed by the U.S. Government or any of its sponsored agencies. Cash collateral received in connection with these loans is invested in short-term money market instruments or affiliated money market funds and is shown as such on the Schedule of Investments. 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 any loss on the collateral invested. Dividends received on cash collateral investments for securities lending transactions, which are net of compensation to counterparties, is included in Dividends from affiliates on the Statement of Operations. The aggregate value of securities out on loan is shown as a footnote on the Statement of Assets and Liabilities, if any. J. FUTURES CONTRACTS -- The Fund may purchase or sell futures contracts. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities as collateral for the account of the broker (the Fund's agent in acquiring the futures position). During the period the futures contracts are open, changes in the value of the contracts are recognized as unrealized gains or losses by recalculating the value of the contracts on a daily basis. Variation margin payments are received or made depending upon whether unrealized gains or losses are incurred. When the contracts are closed, the Fund recognizes a realized gain or loss equal to the difference between the proceeds from, or cost of, the closing transaction and the Fund's basis in the contract. 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. Risks may exceed amounts recognized in the Statement of Assets and Liabilities. 15 AIM STRUCTURED GROWTH FUND 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. 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 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: <Table> <Caption> AVERAGE NET ASSETS RATE - ------------------------------------------------------------------- First $250 million 0.60% - ------------------------------------------------------------------- Next $250 million 0.575% - ------------------------------------------------------------------- Next $500 million 0.55% - ------------------------------------------------------------------- Next $1.5 billion 0.525% - ------------------------------------------------------------------- Next $2.5 billion 0.50% - ------------------------------------------------------------------- Next $2.5 billion 0.475% - ------------------------------------------------------------------- Next $2.5 billion 0.45% - ------------------------------------------------------------------- Over $10 billion 0.425% ___________________________________________________________________ =================================================================== </Table> Under the terms of a new master sub-advisory agreement approved by shareholders of the Fund, effective May 1, 2008, 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). Previously, under the terms of a master sub-advisory agreement between the Advisor and Invesco Institutional (N.A.), Inc., the Advisor paid Invesco Institutional (N.A.), Inc. 40% of the amount of the Advisor's compensation on the sub-advised assets. This agreement was terminated on May 1, 2008. 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 and Institutional Class shares to 1.00%, 1.75%, 1.75%, 1.25% and 0.75% of average daily net assets, respectively, through at least June 30, 2009. 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; (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. These credits are used to pay certain expenses incurred by the Fund. Further, the Advisor has contractually agreed, through at least June 30, 2009, 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 (excluding investments of cash collateral from securities lending) in such affiliated money market funds. For the year ended August 31, 2008, the Advisor waived advisory fees of $2,839 and reimbursed class level expenses of $16,230 for Class A, Class B, Class C and Class R shares in proportion to the relative net assets of such classes. At the request of the Trustees of the Trust, Invesco 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. For the year ended August 31, 2008, Invesco did not reimburse any expenses. 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 year ended August 31, 2008, 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 year ended August 31, 2008, expenses incurred under the agreement are shown in the Statement of Operations as transfer agent fees. 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 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 16 AIM STRUCTURED GROWTH FUND charges that may be paid by any class of shares of the Fund. For the year ended August 31, 2008, 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 year ended August 31, 2008, IADI advised the Fund that IADI retained $2,642 in front-end sales commissions from the sale of Class A shares and $0, $742, $2,875 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--EXPENSE OFFSET ARRANGEMENTS The expense offset arrangements are comprised of (i) transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions and (ii) custodian credits which result from periodic overnight cash balances at the custodian. For the year ended August 31, 2008, the Fund received credits from these arrangements, which resulted in the reduction of the Fund's total expenses of $438. NOTE 4--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 year ended August 31, 2008, the Fund paid legal fees of $2,805 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 5--CASH BALANCES 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.

The Fund's net unrealized appreciation (depreciation) difference is attributable primarily to wash sales. 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 benefits. 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.

This reclassification had no effect on the net assets of the Fund. 18 AIM STRUCTURED GROWTH FUND NOTE 10--SHARE INFORMATION <Table> <Caption> CHANGES IN SHARES OUTSTANDING - ---------------------------------------------------------------------------------------------------------------------- YEAR ENDED AUGUST 31, ------------------------------------------------------- 2008(a) 2007 ------------------------- ------------------------- SHARES AMOUNT SHARES AMOUNT - ---------------------------------------------------------------------------------------------------------------------- Sold: Class A 126,221 $ 1,439,845 754,832 $ 8,442,717 - ---------------------------------------------------------------------------------------------------------------------- Class B 37,404 424,646 52,116 576,888 - ---------------------------------------------------------------------------------------------------------------------- Class C 64,135 718,782 201,234 2,271,388 - ---------------------------------------------------------------------------------------------------------------------- Class R 1,458 15,648 797 8,993 - ---------------------------------------------------------------------------------------------------------------------- Institutional Class 1,601,599 18,008,711 5,931,247 66,326,390 ====================================================================================================================== Issued as reinvestment of dividends: Class A 18,312 218,096 511 5,619 - ---------------------------------------------------------------------------------------------------------------------- Class B 1,576 18,615 75 824 - ---------------------------------------------------------------------------------------------------------------------- Class C 5,708 67,407 80 875 - ---------------------------------------------------------------------------------------------------------------------- Class R 32 386 72 798 - ---------------------------------------------------------------------------------------------------------------------- Institutional Class 477,642 5,698,269 35,784 393,627 ====================================================================================================================== Automatic conversion of Class B shares to Class A shares: Class A 7,720 81,915 2,709 31,228 - ---------------------------------------------------------------------------------------------------------------------- Class B (7,802) (81,915) (2,728) (31,228) ====================================================================================================================== Reacquired: Class A (325,612) (3,573,411) (191,553) (2,188,922) - ---------------------------------------------------------------------------------------------------------------------- Class B (26,522) (282,000) (74,712) (855,912) - ---------------------------------------------------------------------------------------------------------------------- Class C (61,575) (650,031) (79,974) (912,922) - ---------------------------------------------------------------------------------------------------------------------- Class R (14) (152) (59,757) (689,000) - ---------------------------------------------------------------------------------------------------------------------- Institutional Class (784,168) (8,400,037) (484,204) (5,577,887) ====================================================================================================================== 1,136,114 $13,704,774 6,086,529 $67,803,476 ______________________________________________________________________________________________________________________ ====================================================================================================================== </Table> (a) 89% of the outstanding shares of the Fund are owned by affiliated mutual funds.

NOTE 11--NEW ACCOUNTING STANDARD In March 2008, the Financial Accounting Standards Board (FASB) issued 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. It is effective for financial statements issued for fiscal years beginning after November 15, 2008. Management is currently in the process of determining the impact of the standard on the Fund's disclosures in the financial statements. 19 AIM STRUCTURED GROWTH FUND NOTE 12--FINANCIAL HIGHLIGHTS The following schedule presents financial highlights for a share of the Fund outstanding throughout the periods indicated. <Table> <Caption> INCOME (LOSS) FROM INVESTMENT OPERATIONS ------------------------------------ NET GAINS DISTRIBUTIONS (LOSSES) ON ---------------------------------------- NET ASSET NET SECURITIES DIVIDENDS DISTRIBUTIONS VALUE, INVESTMENT (BOTH TOTAL FROM FROM NET FROM NET NET ASSET BEGINNING INCOME REALIZED AND INVESTMENT INVESTMENT REALIZED TOTAL VALUE, END TOTAL OF PERIOD (LOSS)(a) UNREALIZED) OPERATIONS INCOME GAINS DISTRIBUTIONS OF PERIOD RETURN(b) - ----------------------------------------------------------------------------------------------------------------------------------- CLASS A Year ended 08/31/08 $11.45 $ 0.04 $(0.93) $(0.89) $(0.03) $(0.33) $(0.36) $10.20 (8.25)% Year ended 08/31/07 9.93 0.02 1.53 1.55 (0.02) (0.01) (0.03) 11.45 15.63 Year ended 08/31/06(e) 10.00 0.11 (0.18) (0.07) -- -- -- 9.93 (0.70) - ----------------------------------------------------------------------------------------------------------------------------------- CLASS B Year ended 08/31/08 11.35 (0.04) (0.93) (0.97) -- (0.33) (0.33) 10.05 (8.98) Year ended 08/31/07 9.90 (0.07) 1.53 1.46 -- (0.01) (0.01) 11.35 14.76 Year ended 08/31/06(e) 10.00 0.08 (0.18) (0.10) -- -- -- 9.90 (1.00) - ----------------------------------------------------------------------------------------------------------------------------------- CLASS C Year ended 08/31/08 11.35 (0.04) (0.93) (0.97) -- (0.33) (0.33) 10.05 (8.98) Year ended 08/31/07 9.90 (0.07) 1.53 1.46 -- (0.01) (0.01) 11.35 14.76 Year ended 08/31/06(e) 10.00 0.08 (0.18) (0.10) -- -- -- 9.90 (1.00) - ----------------------------------------------------------------------------------------------------------------------------------- CLASS R Year ended 08/31/08 11.44 0.01 (0.94) (0.93) -- (0.33) (0.33) 10.18 (8.55) Year ended 08/31/07 9.92 (0.01) 1.54 1.53 (0.00) (0.01) (0.01) 11.44 15.46 Year ended 08/31/06(e) 10.00 0.10 (0.18) (0.08) -- -- -- 9.92 (0.80) - ----------------------------------------------------------------------------------------------------------------------------------- INSTITUTIONAL CLASS Year ended 08/31/08 11.48 0.07 (0.93) (0.86) (0.06) (0.33) (0.39) 10.23 (7.99) Year ended 08/31/07 9.94 0.05 1.53 1.58 (0.03) (0.01) (0.04) 11.48 15.93 Year ended 08/31/06(e) 10.00 0.12 (0.18) (0.06) -- -- -- 9.94 (0.60) ___________________________________________________________________________________________________________________________________ =================================================================================================================================== <Caption> RATIO OF RATIO OF EXPENSES EXPENSES TO AVERAGE TO AVERAGE NET RATIO OF NET NET ASSETS ASSETS WITHOUT INVESTMENT NET ASSETS, WITH FEE WAIVERS FEE WAIVERS INCOME (LOSS) END OF PERIOD AND/OR EXPENSES AND/OR EXPENSES TO AVERAGE PORTFOLIO (000S OMITTED) ABSORBED ABSORBED NET ASSETS TURNOVER(c) - ------------------------------------------------------------------------------------------------ CLASS A Year ended 08/31/08 $ 4,894 1.00%(d) 1.18%(d) 0.37%(d) 119% Year ended 08/31/07 7,481 1.01 1.29 0.17 91 Year ended 08/31/06(e) 862 1.03(f) 5.52(f) 2.57(f) 7 - ------------------------------------------------------------------------------------------------ CLASS B Year ended 08/31/08 465 1.75(d) 1.93(d) (0.38)(d) 119 Year ended 08/31/07 472 1.76 2.04 (0.58) 91 Year ended 08/31/06(e) 662 1.78(f) 6.27(f) 1.82(f) 7 - ------------------------------------------------------------------------------------------------ CLASS C Year ended 08/31/08 1,911 1.75(d) 1.93(d) (0.38)(d) 119 Year ended 08/31/07 2,065 1.76 2.04 (0.58) 91 Year ended 08/31/06(e) 599 1.78(f) 6.27(f) 1.82(f) 7 - ------------------------------------------------------------------------------------------------ CLASS R Year ended 08/31/08 26 1.25(d) 1.43(d) 0.12(d) 119 Year ended 08/31/07 13 1.26 1.54 (0.08) 91 Year ended 08/31/06(e) 595 1.28(f) 5.77(f) 2.32(f) 7 - ------------------------------------------------------------------------------------------------ INSTITUTIONAL CLASS Year ended 08/31/08 158,699 0.73(d) 0.73(d) 0.64(d) 119 Year ended 08/31/07 163,313 0.75 0.89 0.43 91 Year ended 08/31/06(e) 86,898 0.77(f) 5.20(f) 2.83(f) 7 ________________________________________________________________________________________________ ================================================================================================ </Table> (a) Calculated using average shares outstanding.

PENDING LITIGATION AND REGULATORY INQUIRIES 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 Invesco Aim and IADI (Order No. 05-1318). The WVASC makes findings of fact that Invesco Aim and IADI entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and IADI violated the West Virginia securities laws. The WVASC orders Invesco Aim and IADI to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, Invesco Funds Group, Inc. ("IFG"), Invesco Aim, IADI 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; and - that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and the Employee Retirement Income Security Act of 1974, as amended ("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. The case pending in Illinois State Court regarding fair value pricing was dismissed with prejudice on May 6, 2008. All lawsuits based on allegations of market timing, late trading and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court"). Pursuant to an Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties: (i) a Consolidated Amended Class Action Complaint purportedly brought on behalf of shareholders of the AIM Funds; (ii) a Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint for Violations of ERISA purportedly brought on behalf of participants in the Invesco 401(k) plan. Based on orders issued by the MDL Court, all claims asserted against the AIM Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the Consolidated Amended Fund Derivative Complaint. On September 15, 2006, the MDL Court granted the Invesco defendants' motion to dismiss the Amended Class Action Complaint for Violations of ERISA and dismissed such Complaint. Plaintiff appealed this ruling. On June 16, 2008, the Fourth Circuit Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings. IFG, Invesco Aim, IADI 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, among others, 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 security holders. IFG, Invesco Aim and IADI have advised the Fund that they are providing full cooperation with respect to these inquiries. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, Invesco Aim and/or related entities and individuals in the future. At the present time, management of Invesco Aim and the Fund are unable to estimate the impact, if any, that the outcome of the Pending Litigation and Regulatory Inquiries described above may have on Invesco Aim, IADI or the Fund. 21 AIM STRUCTURED GROWTH FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of AIM Counselor Series Trust and Shareholders of AIM Structured Growth 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 Structured Growth Fund (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2008, 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, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PRICEWATERHOUSECOOPERS LLP October 20, 2008 Houston, Texas 22 AIM STRUCTURED GROWTH 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 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 example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2008, through August 31, 2008. 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 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. <Table> <Caption> - --------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2) (08/31/08) PERIOD(2) RATIO - --------------------------------------------------------------------------------------------------- A $1,000.00 $976.10 $4.97 $1,020.11 $5.08 1.00% - --------------------------------------------------------------------------------------------------- B 1,000.00 972.00 8.67 1,016.34 8.87 1.75 - --------------------------------------------------------------------------------------------------- C 1,000.00 972.00 8.67 1,016.34 8.87 1.75 - --------------------------------------------------------------------------------------------------- R 1,000.00 974.20 6.20 1,018.85 6.34 1.25 - --------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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.

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, 2008, through August 31, 2008. 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 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.

PHOTO] MARKET OVERVIEW Philip Taylor About a year ago or so, we saw warning signs of increasing economic ills -- a weakening housing market, rising inflation and slowing job growth, among others. Nonetheless, U.S. equity markets were performing relatively well. But as the year progressed, the housing market deteriorated, energy prices rose, unemployment increased and the credit crunch grew more widespread. In response, the U.S. Federal Reserve cut short-term interest rate targets to stimulate economic growth and expand market liquidity.(1) Congress and the president worked together to enact an economic stimulus plan, one facet of which was to provide more than 112 million taxpayers with $92 billion in tax rebates.(2) Historically, actions such as these have stimulated economic growth. Unfortunately, other factors were simultaneously at work behind the scenes, and the market began to reveal the strain of those factors. HOW WE GOT HERE The market stresses we saw over the past year were the result of years of lax lending associated with the recent housing boom. Mortgage loans of questionable quality were bundled into hard-to-value securities that were sold to, and traded among, financial institutions. The value of those securities declined; more institutions sought to sell them and fewer institutions were willing to buy them. As a result, financial institutions' access to credit declined and the value of their holdings declined -- preventing normal trading among banks and other financial institutions. In October 2008, Congress enacted a plan, the Troubled Assets Relief Program, authorizing the U.S. Department of the Treasury to purchase up to $700 billion in troubled mortgage-related assets -- the largest and most direct effort to resolve a credit crisis in the last half century. INVESTING IN A VOLATILE MARKET Whether or not markets recover in the short term, the kind of volatility we've seen of late is a good reminder that in times of market uncertainty, it's wise to stay true to three timeless investing principles: o INVEST FOR THE LONG TERM. Short-term fluctuations have always been a reality of the markets. I urge you to stick to your investment plan and stay focused on your long-term goals. o DIVERSIFY. Although diversification doesn't eliminate the risk of loss or guarantee a profit, a careful selection of complementary asset classes may potentially cushion your portfolio against excessive volatility. o STAY FULLY INVESTED. Trying to time the market is a gamble, not an investment strategy. A sound investment strategy includes viewing market volatility as a matter of course, not a reason to panic. That leads me to a fourth principle we believe may be critical to your success: Work with a trusted financial advisor. An experienced advisor who knows your goals and situation can be your most valuable asset, particularly during times of market volatility. Your advisor can provide guidance and can monitor your investments to ensure they're on course. Recent market volatility has been disconcerting for everyone. Remember, however, that many of history's significant buying opportunities were the result of short-term economic crises that, in their time, were considered unprecedented. I believe current market volatility and uncertainty may represent a buying opportunity for patient, long-term investors. Invesco Aim's portfolio managers are working diligently on your behalf to capitalize on this situation. OUR NEW BRAND IDENTITY While market conditions are obviously at the top of everyone's mind, there are some significant changes I want to share with you: We have a new name and a new brand -- Invesco Aim. Our parent company, Invesco Ltd., is one of the world's largest and most diversified global investment managers with $450 billion in assets under management as of August 31, 2008. Invesco has 5,300 employees in 13 investment centers worldwide serving clients in 100 countries. This provides you: o Diversified investment strategies from distinct management teams around the globe. o A range of investment products to help you achieve your financial goals. o The peace of mind professional asset management and a diversified investment portfolio can provide. While our name may have changed, our commitment to putting shareholders first, helping clients achieve their investment goals and providing excellent customer service will never change. If you have questions about this report or your account, please contact one of our client service representatives at 800 959 4246. Thank you for your continued confidence, and we look forward to serving you. Sincerely, /S/ PHILIP TAYLOR Philip Taylor Senior Managing Director, Invesco Ltd. CEO, Invesco Aim October 20, 2008 (1) U.S. Federal Reserve Board; (2) U.S. Department of the Treasury 2 AIM STRUCTURED VALUE FUND Dear Fellow Shareholders: As I write this letter, turbulent financial markets are causing considerable investor anxiety, reminding us again that markets are cyclical and the correction of excess is often painful, at least in the short term. [CROCKETT Your Board of Trustees believes in the wisdom of a long-term perspective and consistent investment PHOTO] discipline. We continue to put your interests first in the effort to improve investment performance, contain shareholder costs and uphold the highest ethical standards. Bruce Crockett We remain enthusiastic about the global reach and investment expertise that Invesco, a leading independent global investment management company, brings to the management of AIM Funds as the parent company of the advisors. The diverse investment strategies deployed throughout the worldwide network of Invesco investment centers has helped strengthen the management of many AIM Funds. The rebranding of the Funds' management company as Invesco Aim was followed by the launch of an upgraded, investor-friendly website (invescoaim.com); a new mountain logo using a Himalayan peak to symbolize stability, endurance, strength and longevity; and a new ad campaign. Emphasizing Invesco Aim's focus and investment quality, the ads will appear in financial publications such as Barron's and Investment News through the end of 2008. 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." We have recently completed another active proxy voting season during which we acted on your behalf to double the number of votes in favor of separating the roles of chairman and CEO at the companies whose shares your Funds hold. We also continued to support the movement for shareholders to have a bigger role in approving executive compensation, initiatives known as "say on pay." Like virtually all other mutual fund complexes, AIM Funds abstain from voting on social issues as a matter of policy, and I would be interested to hear your thoughts on this policy. As always, you are welcome to email your questions or comments to me at bruce@brucecrockett.com. The dialogue that has been established in this way has been instructive for your Board, and we want it to continue. Although the production schedule for Fund annual reports and prospectuses allows me to write these letters of general report and response just twice a year, please be assured that your comments are received, welcomed and heard in the interim. We look forward to hearing from you and to representing you. Sincerely, /S/ BRUCE CROCKETT Bruce L.

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 six separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently offers five different classes of shares: Class A, Class B, Class C, Class R 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 shares 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. 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 long-term growth of capital. The following is a summary of the significant accounting policies followed by the Fund in the preparation of its financial statements. 14 AIM STRUCTURED VALUE FUND 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 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 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 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. 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. 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 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. 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 may 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 and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Securities for which market quotations are not readily available or are 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. 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 as 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 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, 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 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 15 AIM STRUCTURED VALUE FUND 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 and 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. H. INDEMNIFICATIONS -- 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. The risk of material loss as a result of such indemnification claims is considered remote. I. SECURITIES LENDING -- 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 by the securities lending provider. Such collateral will be cash or debt securities issued or guaranteed by the U.S. Government or any of its sponsored agencies. Cash collateral received in connection with these loans is invested in short-term money market instruments or affiliated money market funds and is shown as such on the Schedule of Investments. 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 any loss on the collateral invested. Dividends received on cash collateral investments for securities lending transactions, which are net of compensation to counterparties, is included in Dividends from affiliates on the Statement of Operations. The aggregate value of securities out on loan is shown as a footnote on the Statement of Assets and Liabilities, if any. J. FUTURES CONTRACTS -- The Fund may purchase or sell futures contracts. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities as collateral for the account of the broker (the Fund's agent in acquiring the futures position). During the period the futures contracts are open, changes in the value of the contracts are recognized as unrealized gains or losses by recalculating the value of the contracts on a daily basis. Variation margin payments are received or made depending upon whether unrealized gains or losses are incurred. When the contracts are closed, the Fund recognizes a realized gain or loss equal to the difference between the proceeds from, or cost of, the closing transaction and the Fund's basis in the contract. 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. Risks may exceed amounts recognized in the Statement of Assets and Liabilities. 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. 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 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: <Table> <Caption> AVERAGE NET ASSETS RATE - ------------------------------------------------------------------- First $250 million 0.60% - ------------------------------------------------------------------- Next $250 million 0.575% - ------------------------------------------------------------------- Next $500 million 0.55% - ------------------------------------------------------------------- Next $1.5 billion 0.525% - ------------------------------------------------------------------- Next $2.5 billion 0.50% - ------------------------------------------------------------------- Next $2.5 billion 0.475% - ------------------------------------------------------------------- Next $2.5 billion 0.45% - ------------------------------------------------------------------- Over $10 billion 0.425% ___________________________________________________________________ =================================================================== </Table> 16 AIM STRUCTURED VALUE FUND Under the terms of a new master sub-advisory agreement approved by shareholders of the Fund, effective May 1, 2008, 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). Previously, under the terms of a master sub-advisory agreement between the Advisor and Invesco Institutional (N.A.), Inc., the Advisor paid Invesco Institutional (N.A.), Inc. 40% of the amount of the Advisor's compensation on the sub-advised assets. This agreement terminated on May 1, 2008. 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 and Institutional Class shares to 1.00%, 1.75%, 1.75%, 1.25% and 0.75% of average daily net assets, respectively, through at least June 30, 2009. 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; (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. These credits are used to pay certain expenses incurred by the Fund. Further, the Advisor has contractually agreed, through at least June 30, 2009, 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 (excluding investments of cash collateral from securities lending) cash in such affiliated money market funds. For the year ended August 31, 2008, the Advisor waived advisory fees $29,524 and reimbursed class level expenses of $9,491, $2,884, $796, $51 and $5,576 expenses of Class A, Class B, Class C, Class R and Institutional Class shares, respectively. At the request of the Trustees of the Trust, Invesco 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, 2008, Invesco reimbursed expenses of the Fund in the amount of $36. 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 year ended August 31, 2008, 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 year ended August 31, 2008, expenses incurred under the agreement are shown in the Statement of Operations as transfer agent fees. 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 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 year ended August 31, 2008, 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 year ended August 31, 2008, IADI advised the Fund that IADI retained $1,711 in front-end sales commissions from the sale of Class A shares and $0, $101, $46 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--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, 2008, the Fund received credits from this arrangement, which resulted in the reduction of the Fund's total expenses of $302. NOTE 4--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 17 AIM STRUCTURED VALUE FUND 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 year ended August 31, 2008, the Fund paid legal fees of $2,727 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 5--CASH BALANCES 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.

The Fund's net unrealized appreciation (depreciation) difference is attributable primarily to wash sales. 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 benefits. 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, 2008 which expires as follows: <Table> <Caption> CAPITAL LOSS EXPIRATION CARRYFORWARD* - ----------------------------------------------------------------------------------------------- August 31, 2016 $430,774 _______________________________________________________________________________________________ =============================================================================================== </Table> 18 AIM STRUCTURED VALUE FUND NOTE 8--INVESTMENT SECURITIES The aggregate amount of investment securities (other than short-term securities, U.S. Treasury obligations and money market funds, if any) purchased and sold by the Fund during the year ended August 31, 2008 was $146,813,272 and $121,129,893, respectively.

This reclassification had no effect on the net assets of the Fund.

NOTE 11--NEW ACCOUNTING STANDARD In March 2008, the Financial Accounting Standards Board (FASB) issued 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. It is effective for financial statements issued for fiscal years beginning after November 15, 2008. Management is currently in the process of determining the impact of the standard on the Fund's disclosures in the financial statements. 19 AIM STRUCTURED VALUE FUND NOTE 12--FINANCIAL HIGHLIGHTS The following schedule presents financial highlights for a share of the Fund outstanding throughout the periods indicated. <Table> <Caption> Income (loss) from investment operations ------------------------------------- NET GAINS Distributions (LOSSES) ------------------------- NET ASSET ON SECURITIES DIVIDENDS DISTRIBUTIONS VALUE, NET (BOTH TOTAL FROM FROM NET FROM NET NET ASSET BEGINNING INVESTMENT REALIZED AND INVESTMENT INVESTMENT REALIZED TOTAL VALUE, END OF PERIOD INCOME(a) UNREALIZED) OPERATIONS INCOME GAINS DISTRIBUTIONS OF PERIOD - -------------------------------------------------------------------------------------------------------------------------- CLASS A Year ended 08/31/08 $11.40 $0.16 $(1.70) $(1.54) $(0.11) $(0.21) $(0.32) $ 9.54 Year ended 08/31/07 10.44 0.14 0.89 1.03 (0.06) (0.01) (0.07) 11.40 Year ended 08/31/06(e) 10.00 0.20 0.24 0.44 -- -- -- 10.44 - -------------------------------------------------------------------------------------------------------------------------- CLASS B Year ended 08/31/08 11.35 0.08 (1.70) (1.62) (0.02) (0.21) (0.23) 9.50 Year ended 08/31/07 10.40 0.05 0.91 0.96 -- (0.01) (0.01) 11.35 Year ended 08/31/06(e) 10.00 0.16 0.24 0.40 -- -- -- 10.40 - -------------------------------------------------------------------------------------------------------------------------- CLASS C Year ended 08/31/08 11.33 0.08 (1.69) (1.61) (0.02) (0.21) (0.23) 9.49 Year ended 08/31/07 10.40 0.05 0.89 0.94 -- (0.01) (0.01) 11.33 Year ended 08/31/06(e) 10.00 0.16 0.24 0.40 -- -- -- 10.40 - -------------------------------------------------------------------------------------------------------------------------- CLASS R Year ended 08/31/08 11.38 0.13 (1.70) (1.57) (0.08) (0.21) (0.29) 9.52 Year ended 08/31/07 10.42 0.11 0.90 1.01 (0.04) (0.01) (0.05) 11.38 Year ended 08/31/06(e) 10.00 0.18 0.24 0.42 -- -- -- 10.42 - -------------------------------------------------------------------------------------------------------------------------- INSTITUTIONAL CLASS Year ended 08/31/08 11.43 0.19 (1.71) (1.52) (0.14) (0.21) (0.35) 9.56 Year ended 08/31/07 10.45 0.17 0.89 1.06 (0.07) (0.01) (0.08) 11.43 Year ended 08/31/06(e) 10.00 0.21 0.24 0.45 -- -- -- 10.45 __________________________________________________________________________________________________________________________ ========================================================================================================================== <Caption> RATIO OF RATIO OF EXPENSES EXPENSES TO AVERAGE TO AVERAGE NET RATIO OF NET NET ASSETS ASSETS WITHOUT INVESTMENT NET ASSETS, WITH FEE WAIVERS FEE WAIVERS INCOME TOTAL END OF PERIOD AND/OR EXPENSES AND/OR EXPENSES TO AVERAGE PORTFOLIO RETURN(b) (000S OMITTED) ABSORBED ABSORBED NET ASSETS TURNOVERS(c) - ------------------------------------------------------------------------------------------------------------- CLASS A Year ended 08/31/08 (13.83)% $ 4,088 1.01%(d) 1.42%(d) 1.57%(d) 88% Year ended 08/31/07 9.80 2,011 1.01 1.36 1.17 62 Year ended 08/31/06(e) 4.40 856 1.03(f) 5.80(f) 4.59(f) 5 - ------------------------------------------------------------------------------------------------------------- CLASS B Year ended 08/31/08 (14.50) 1,031 1.76(d) 2.17(d) 0.82(d) 88 Year ended 08/31/07 9.20 718 1.76 2.11 0.42 62 Year ended 08/31/06(e) 4.00 790 1.78(f) 6.55(f) 3.84(f) 5 - ------------------------------------------------------------------------------------------------------------- CLASS C Year ended 08/31/08 (14.43) 235 1.76(d) 2.17(d) 0.82(d) 88 Year ended 08/31/07 9.01 156 1.76 2.11 0.42 62 Year ended 08/31/06(e) 4.00 632 1.78(f) 6.55(f) 3.84(f) 5 - ------------------------------------------------------------------------------------------------------------- CLASS R Year ended 08/31/08 (14.08) 18 1.26(d) 1.67(d) 1.32(d) 88 Year ended 08/31/07 9.65 10 1.26 1.61 0.92 62 Year ended 08/31/06(e) 4.20 625 1.28(f) 6.05(f) 4.34(f) 5 - ------------------------------------------------------------------------------------------------------------- INSTITUTIONAL CLASS Year ended 08/31/08 (13.64) 134,272 0.75(d) 0.78(d) 1.83(d) 88 Year ended 08/31/07 10.13 134,931 0.75 0.94 1.43 62 Year ended 08/31/06(e) 4.50 73,488 0.77(f) 5.50(f) 4.85(f) 5 _____________________________________________________________________________________________________________ ============================================================================================================= </Table> (a) Calculated using average shares outstanding.

PENDING LITIGATION AND REGULATORY INQUIRIES 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 Invesco Aim and IADI (Order No. 05-1318). The WVASC makes findings of fact that Invesco Aim and IADI entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and IADI violated the West Virginia securities laws. The WVASC orders Invesco Aim and IADI to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, Invesco Funds Group, Inc. ("IFG"), Invesco Aim, IADI 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; and - that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and the Employee Retirement Income Security Act of 1974, as amended ("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. The case pending in Illinois State Court regarding fair value pricing was dismissed with prejudice on May 6, 2008. All lawsuits based on allegations of market timing, late trading and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court"). Pursuant to an Order of the MDL Court, plaintiffs in these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties: (i) a Consolidated Amended Class Action Complaint purportedly brought on behalf of shareholders of the AIM Funds; (ii) a Consolidated Amended Fund Derivative Complaint purportedly brought on behalf of the AIM Funds and fund registrants; and (iii) an Amended Class Action Complaint for Violations of ERISA purportedly brought on behalf of participants in the Invesco 401(k) plan. Based on orders issued by the MDL Court, all claims asserted against the AIM Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the Consolidated Amended Fund Derivative Complaint. On September 15, 2006, the MDL Court granted the Invesco defendants' motion to dismiss the Amended Class Action Complaint for Violations of ERISA and dismissed such Complaint. Plaintiff appealed this ruling. On June 16, 2008, the Fourth Circuit Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings. IFG, Invesco Aim, IADI 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, among others, 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 security holders. IFG, Invesco Aim and IADI have advised the Fund that they are providing full cooperation with respect to these inquiries. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, Invesco Aim and/or related entities and individuals in the future. At the present time, management of Invesco Aim and the Fund are unable to estimate the impact, if any, that the outcome of the Pending Litigation and Regulatory Inquiries described above may have on Invesco Aim, IADI or the Fund. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees of AIM Counselor Series Trust and Shareholders of AIM Structured Value 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 Structured Value Fund (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2008, 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, 2008 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PRICEWATERHOUSECOOPERS LLP October 20, 2008 Houston, Texas 22 AIM STRUCTURED VALUE 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 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 example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2008, through August 31, 2008. 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 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. <Table> <Caption> - --------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2) (08/31/08) PERIOD(2) RATIO - --------------------------------------------------------------------------------------------------- A $1,000.00 $951.20 $4.90 $1,020.11 $5.08 1.00% - --------------------------------------------------------------------------------------------------- B 1,000.00 947.20 8.57 1,016.34 8.87 1.75 - --------------------------------------------------------------------------------------------------- C 1,000.00 947.10 8.57 1,016.34 8.87 1.75 - --------------------------------------------------------------------------------------------------- R 1,000.00 948.20 6.12 1,018.85 6.34 1.25 - --------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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.

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, 2008, through August 31, 2008. 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 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. <Table> <Caption> - ----------------------------------------------------------------------------------------------------------- HYPOTHETICAL (5% ANNUAL RETURN BEFORE ACTUAL EXPENSES) ------------------------------------------------------ BEGINNING ENDING EXPENSES ENDING EXPENSES ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE PAID DURING ACCOUNT VALUE PAID DURING EXPENSE CLASS (03/01/08) (08/31/08)(1) PERIOD(2) (08/31/08) PERIOD(2) RATIO - ----------------------------------------------------------------------------------------------------------- Institutional $1,000.00 $951.20 $3.68 $1,021.37 $3.81 0.75% - ----------------------------------------------------------------------------------------------------------- </Table> (1) The actual ending account value is based on the actual total return of the Fund for the period March 1, 2008, through August 31, 2008, 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 Audit Committee also has considered whether the provision of non-audit services that were rendered to Invesco Aim and Invesco Aim Affiliates that were not required to be pre-approved pursuant to SEC regulations, if any, is compatible with maintaining PWC's independence. To the extent that such services were provided, the Audit Committee determined that the provision of such services is compatible with PWC maintaining independence with respect to the Registrant. 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, Invesco Aim Advisors, Inc. ("Invesco 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 two matters that required further consideration under the SEC's auditor independence rules. First, PwC was engaged to perform services to an affiliate of Invesco Ltd., including (a) consulting with respect to the acquisition by the affiliate of certain assets from a third party; and (b) providing expert testimony in connection with any arbitration proceeding or litigation arising from or relating to the transaction. SEC rules provide that an accountant is not independent if, at any point during the audit and professional engagement period, the accountant provides expert services unrelated to the audit to an audit client. Specifically, PwC would not be permitted to provide expert testimony nor perform other services in support of the client or its counsel in connection with a proceeding. Within days of being engaged to provide the services it was determined that some of the services contemplated in the engagement terms would be inconsistent with the SEC's auditor independence rules. A review of the services performed pursuant to the original agreement was conducted. It was concluded that the services performed were not inconsistent with the SEC's independence rules. Following the review, the initial engagement terms were modified to limit PwC's services to those permitted under the rules. Second, an employee of PwC served as a nominee shareholder (effectively equivalent to a Trustee) of various companies or trusts since 2001. Some of these companies held shares of INVESCO Nippon Warrants Fund (the "Investment."), an affiliate of Invesco Ltd., formerly known as AMVESCAP PLC (the "Company"). The investment, which consisted of 2,070 shares, was initially entered into during July 1, 2001 - December 31, 2005. PwC informed the Audit Committee that the second matter could have constituted an investment in an affiliate of an audit client in violation of Rule 2-01(c)(1) of Regulation S-X. PwC advised the Audit Committee that it believes its independence had not been adversely affected as it related to the audits of the Funds. In reaching this conclusion, PwC noted that during the time of its audit, the engagement team was not aware of the investment, as it relates to the second matter, and that PwC did not believe either of these situations affected PwC's ability to act objectively and impartially and to issue a report on financial statements as the Funds' independent auditor. Based upon PwC's review and discussion, the audit committee concurred with PwC's conclusions in relation to its independence. ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS. Not applicable. ITEM 6.
