OUR SOLUTIONS.] - REGISTERED TRADEMARK - [AIM INVESTMENTS LOGO] - REGISTERED TRADEMARK - AIM ADVANTAGE HEALTH SCIENCES FUND SEEKS CAPITAL GROWTH. .. Unless otherwise stated, information presented in this report is as of August 31, 2005, and is based on total net assets. ABOUT SHARE CLASSES .. Class B shares are not available as an investment for retirement plans maintained pursuant to Section 401 of the Internal Revenue Code, including 401(k) plans, money purchase pension plans and profit sharing plans. Plans that had existing accounts invested in Class B shares prior to September 30, 2003, will continue to be allowed to make additional purchases. PRINCIPAL RISKS OF INVESTING IN THE FUND .. Investing in smaller companies involves greater risk than investing in more established companies, such as business risk, significant stock price fluctuations and illiquidity. .. Investing in a single-sector or single-region mutual fund involves greater risk and potential reward than investing in a more diversified fund. .. The Fund is nondiversified, which increases risks as well as potential rewards. .. Portfolio turnover is greater than that of most funds, which may affect performance. .. The Fund seeks to participate in the initial public offering (IPO) market, and a significant portion of the Fund's returns may be attributable to IPO investments. While IPOs may significantly enhance Fund returns, there is no guarantee that the market for these securities will continue to be robust. Also, this type of security may have limited liquidity. .. The Fund may invest 100% of its assets in the securities of non-U.S. issuers. International investing presents certain risks not associated with investing solely in the United States. These include risks relating to fluctuations in the value of the U.S. dollar relative to the values of other currencies, the custody arrangements made for the Fund's foreign holdings, differences in accounting, political risks and the lesser degree of public information required to be provided by non-U.S. companies. .. Leveraging and short-selling, along with other hedging strategies, present higher risks, but also offer greater potential rewards. Since stock prices can rise without limit, short sales are riskier because of unlimited exposure to loss until the position is covered. The Fund, which is not a complete investment program, may not be appropriate for all investors. There is no guarantee that the Fund managers' investment strategies will help investors attain their goals. Please see the prospectus for more information about specific investment strategies and risks. .. The Fund may invest up to 15% of its assets in illiquid securities. The Fund's investments include securities of privately held joint venture capital companies which are considered to be illiquid. A security is considered to be illiquid if the Fund is unable to sell such security at a fair price within a reasonable amount of time. Investments in privately held joint venture capital securities are inherently risky because the markets for these companies' products may never materialize and the Fund could ultimately lose its entire investment. ABOUT INDEXES USED IN THIS REPORT .. The unmanaged LIPPER HEALTH/BIOTECH FUND INDEX represents an average of the 30 largest health and biotechnology funds tracked by Lipper, Inc., an independent mutual fund performance monitor. .. The MORGAN STANLEY HEALTH CARE PRODUCT INDEX is an equal-dollar weighted index of companies involved in the business of pharmaceuticals, including biotechnology and medical technology. .. The unmanaged Standard & Poor's Composite Index of 500 Stocks (the S&P 500 - --REGISTERED TRADEMARK-- Index) is an index of common stocks frequently used as a general measure of U.S. stock market performance. .. A direct investment cannot be made in an index. Unless otherwise indicated, index results include reinvested dividends, and they do not reflect sales charges. Performance of an index of funds reflects fund expenses; performance of a market index does not. .. The Fund is not managed to track the performance of any particular index, including the indexes defined here, and consequently, the performance of the Fund may deviate significantly from the performance of the indexes. OTHER INFORMATION .. The returns shown in management's discussion of Fund performance are based on net asset values calculated for shareholder transactions. Generally accepted accounting principles require adjustments to be made to the net assets of the Fund at period end for financial reporting purposes, and as such, the net asset values for shareholder transactions and the returns based on those net asset values may differ from the net asset values and returns reported in the Financial Highlights. .. Industry classifications used in this report are generally according to the Global Industry Classification Standard, which was developed by and is the exclusive property and a service mark of Morgan Stanley Capital International Inc. and Standard & Poor's. The Fund provides a complete list of its holdings four times in each fiscal year, at the quarter-ends. For the second and fourth quarters, the lists appear in the Fund's semiannual and annual reports to shareholders. For the first and third quarters, the Fund files the lists with the Securities and Exchange Commission (SEC) on Form N-Q. The most recent list of portfolio holdings is available at AIMinvestments.com. From our home page, click on Products & Performance, then Mutual Funds, then Fund Overview. Select your Fund from the drop-down menu and click on Complete Quarterly Holdings. Shareholders can also look up the Fund's Forms N-Q on the SEC's Web site at sec.gov.

Most equity indexes, both domestic and international, ended up producing double-digit returns for the fiscal year.

GRAHAM We would like to call your attention to two new elements in this report on your Fund. First, on Page 2, is a letter from Bruce Crockett, the independent Chair of the Board of Trustees of the AIM Funds. We first introduced you to Mr. Crockett in the annual report on your Fund dated September 30, 2004. Mr. Crockett has been on our Funds' Board since 1992; he assumed his responsibilities as Chair in October 2004. [WILLIAMSON PHOTO] Mr. Crockett has expressed an interest in keeping shareholders informed of the work of the Board regularly via letters in the Fund reports. We certainly consider this a valuable addition to the reports. The Board is charged with looking out for the interests of shareholders, and Mr. Crockett's letter provides insight into some of the many issues the Board addresses in governing your Fund. MARK H. WILLIAMSON One of the most important decisions the Board makes each year is whether to approve the advisory agreement your Fund has with AIM. Essentially, this agreement hires AIM to manage the assets in your Fund. A discussion of the factors the Board considered in reviewing the agreement is the second new element in the report, and we encourage you to read it. It appears on Pages 8 and 9. Further information about the markets, your Fund, and investing in general is always available on our widely acclaimed Web site, AIMinvestments.com. We invite you to visit it frequently. We at AIM remain committed to building solutions to help you meet your investment goals. We thank you for your continued participation in AIM Investments --REGISTERED TRADEMARK--.

[CROCKETT PHOTO] At our most recent meeting in June 2005, your Board approved voluntary fee reductions from A I M Advisors, Inc. (AIM) that save shareholders approximately $20.8 million annually, based on asset levels as of March 31, 2005. The majority of these expense reductions, which took effect July 1, 2005, will be achieved by a permanent reduction to 0.25% of the Rule 12b-1 fees on Class A and Class A3 shares of those AIM Funds that previously charged these fees at a higher rate. BRUCE L. CROCKETT Our June meeting, which was the culmination of more than two and one-half months of review and discussions, took place over a three-day period. The meeting included your Board's annual comprehensive evaluation of each fund's advisory agreement with AIM. After this evaluation, in which questions about fees, performance and operations were addressed by AIM, your Board approved all advisory agreements for the year beginning July 1, 2005. You can find information on the factors considered and conclusions reached by your Board in its evaluation of each fund's advisory agreement at AIMinvestments.com. (Go to "Products & Performance" and click on "Investment Advisory Agreement Renewals.") The advisory agreement information about your Fund is also included in this annual report on Pages 8 and 9. I encourage you to review it. Together with monitoring fund expenses, fund performance is your Board's priority. Our initial goal is to work with AIM to bring about improvement in every AIM Fund that has been underperforming its category. Your Board has a well-defined process and structure for monitoring all funds and identifying and assisting AIM in improving underperforming funds. Our Investments Committee--which functions along with Audit, Governance, Valuation and Compliance Committees--is the only one of these five standing committees to include all 13 independent Board members. Further, our Investments Committee is divided into three underlying subcommittees, each responsible for, among other things, reviewing the performance, fees and expenses of the funds that have been assigned to it. At subcommittee meetings, held throughout the year, the performance of every AIM Fund is evaluated. If a fund has underperformed its peer group for a meaningful period, we work closely with AIM to discover the causes and help develop the right responses. In some cases, AIM may determine that a change in portfolio management strategy or portfolio managers is required. In other cases, where a fund no longer seems viable, it may be merged with a similar fund, being careful to consider the needs of all shareholders affected by the decision. Following AIM's recommendation and your Board's approval, eight funds were recently merged. Be assured that your Board is working closely with the management of AIM to help you reach your investment goals. Should you or your advisor have questions or comments about the governance of AIM Funds, I invite you to write to me at AIM Investments, AIM Investments Tower, 11 Greenway Plaza, Suite 100, Houston, TX 77046. Your Board looks forward to keeping you informed about the governance of your funds. Sincerely, /s/ BRUCE L. CROCKETT Bruce L. Crockett Independent Chair On Behalf of the Board of Trustees AIM Funds October 13, 2005 2 AIM ADVANTAGE HEALTH SCIENCES FUND MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE - -------------------------------------------------------------------------------- PERFORMANCE SUMMARY We are pleased to report that for the fiscal year ended August 31, 2005, Class A shares of AIM Advantage Health Sciences Fund returned 18.35% at net asset value, outperforming the broad market. We believe this outperformance was due to general strength in the health care sector and particular strength in health care services stocks and managed care stocks. Your Fund also outperformed its style-specific index. We attribute its outperformance to its health care services holdings, which performed well in advance of the Medicare Modernization Act, which will offer Medicare recipients insurance coverage for their prescription drugs. The index had no exposure to health care services stocks. - -------------------------------------------------------------------------------- FUND VS.

We typically invest in four segments of the health care sector: pharmaceuticals, bio-technology, medical technology and health care services. We look for companies that are financially healthy and, in our opinion, likely to sustain their profitability. We assess the long-term commercial potential of each company's current and prospective products, especially products that meet otherwise unfilled market needs. In addition, we may "short" stocks--borrowing a stock when we believe it is likely to decline in value, later repurchasing it and replacing it at a lower price, allowing us to profit from the decline. We may, for example, short stocks of companies that our research suggests are facing product obsolescence. - -------------------------------------------------------------------------------- PORTFOLIO COMPOSITION TOP 10 EQUITY LONG POSITIONS* By industry, based on total investments Long and short positions Pharmaceuticals 38.2% 1.

We seek to manage risk by generally: .. limiting investments in a single stock .. diversifying across industries .. monitoring political trends that could negatively affect a specific industry We may sell a holding when: .. we find a more attractive investment .. we see a deterioration of a company's fundamentals .. a company fails to capitalize on a market opportunity .. a change in management occurs MARKET CONDITIONS AND YOUR FUND In July, U.S. Federal Reserve Board Chairman Alan Greenspan reported that "our baseline outlook for the U.S. economy is one of sustained economic growth and contained inflation pressures." The biggest potential threats to continued economic expansion were rising short-term interest rates and rising energy prices. But because most health care spending is not dependent on economic conditions, the health care sector was less affected by these trends than were some other sectors. As a group, health care stocks within the S&P 500 Index provided high single-digit returns for the fiscal year, underperforming the index as a whole. Nonetheless, many investors favored health care stocks--both because they are less sensitive to the economy and because many larger, more established (continued) Continued from inside front cover A description of the policies and procedures that the Fund uses to determine how to vote proxies relating to portfolio securities is available without charge, upon request, from our Client Services department at 800-959-4246 or on the AIM Web site, AIMinvestments.com.

The information is also available on the SEC Web site, sec.gov. 3 health care companies pay relatively attractive dividends. We share the view that regardless of short-term economic conditions, the health care sector is likely to benefit from an aging population over the long term. For the fiscal year, health care services and managed health care stocks were among the sector's strongest performers. Factors contributing to their positive performance included: .. aggressive cost cutting .. continued pricing power .. growing membership as unemployment declined Also, investors recognized the likely positive impact of the Medicare Modernization Act on such companies when that law becomes effective in January 2006. PacifiCare and Community Health Systems were among the health care services and managed health care holdings that contributed to Fund performance during the reporting period. PacifiCare, for example, has long been regarded as a well-managed industry leader, but its stock got an added boost when the company announced in July that it would merge with UnitedHealth Group (not a Fund holding). Biotechnology stocks performed quite well over the year, particularly stocks of larger and more established biotech companies. Reasons for their strength included strong revenue and earnings growth, positive clinical trial data for new drugs designed to treat underserved diseases and conditions, and heightened merger activity initiated by several large-cap pharmaceutical companies. Over the year, we increased our biotech holdings. Because individual biotech stocks can be volatile, as the fiscal year drew to a close we began increasing our "short" exposure to the biotech industry. We believe this strategy helps reduce your Fund's volatility. In considering whether or not to short a stock, we looked for near-term catalysts that we believed were likely to send a stock's price lower--catalysts including drug approval timelines, releases of clinical trial data and earnings. Among the biotech stocks we shorted during the fiscal year were Cephalon and Onyx Pharmaceuticals. Cephalon, a biopharmaceutical company, faces upcoming patent expirations for two of its three biggest products: sleep-disorder drug Provigil and pain-management drug Actiq. Onyx Pharmaceuticals' lead drug candidate, Sorafenib, is currently in phase III clinical development. We believed the potential for positive news about the drug was already priced into the stock. By the end of the fiscal year, we closed out our position in both of these stocks and no longer held them in the portfolio. In contrast to biotech stocks, many large-cap pharmaceutical stocks continued to perform poorly. While pharmaceutical stocks benefited from the rotation into defensive growth stocks during the reporting period, they were hindered by concerns about patent expirations, restructuring initiatives and a dearth of promising new "blockbuster" products in their pipelines. As a result, pharmaceutical stocks, which accounted for almost 40% of Fund assets at the close of the fiscal year, had only a marginal negative effect on Fund performance. The performance of individual pharmaceutical stocks varied widely because of company-specific news. Roche Holding and Protein Design Labs benefited from their collaboration with Genentech (not a Fund holding) on a promising new cancer drug, Avastin; Roche owns 56% of Genentech. Forest Labs hindered Fund performance due to increasing generic competition and because its product pipeline appears to have faltered. As a result, we reduced our exposure to Forest Labs before the close of the fiscal year. IN CLOSING We remain optimistic about the potential of the health care sector, given demographic trends and people's desire to prolong and improve the quality of their lives. As always, we thank you for your continued investment in AIM Advantage Health Sciences Fund.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2005, through August 31, 2005. ACTUAL EXPENSES The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the table under the heading entitled "Actual Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The Fund's actual cumulative total returns at net asset value after expenses for the six months ended August 31, 2005, appear in the table "Cumulative Total Returns" on Page 7. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions, and redemption fees, if any. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- ACTUAL HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES) BEGINNING ACCOUNT ENDING ACCOUNT EXPENSES ENDING ACCOUNT EXPENSES SHARE VALUE VALUE PAID DURING VALUE PAID DURING CLASS (3/1/05) (8/31/05)/1/ PERIOD/2/,/3/ (8/31/05) PERIOD/2/,/4/ A $ 1,000.00 $ 1,131.20 $ 14.07 $ 1,012.00 $ 13.29 B 1,000.00 1,127.30 17.69 1,008.57 16.71 C 1,000.00 1,127.10 17.69 1,008.57 16.71 /1/ The actual ending account value is based on the actual total return of the Fund for the period March 1, 2005, through August 31, 2005, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund's expense ratio and a hypothetical annual return of 5% before expenses.

We believe that a logarithmic chart is more effective than other types of charts in illustrating changes in value during the early years shown in the chart. The vertical axis, the one that indicates the dollar value of an investment, is constructed with each segment representing a percent change in the value of the investment. In this chart, each segment represents a doubling, or 100% change, in the value of the investment. In other words, the space between $5,000 and $10,000 is the same size as between $10,000 and $20,000. - -------------------------------------------------------------------------------- AVERAGE ANNUAL TOTAL RETURNS As of 8/31/05, including applicable sales charges CLASS A SHARES Inception (1/23/92) 7.93% 10 Years 8.30 5 Years -5.51 1 Year 11.81 CLASS B SHARES Inception (5/15/01) 1.77% 1 Year 12.52 CLASS C SHARES Inception (5/15/01) 1.43% 1 Year 16.49 ================================================================================ AVERAGE ANNUAL TOTAL RETURNS As of 6/30/05, most recent calendar quarter-end, including applicable sales charges CLASS A SHARES Inception (1/23/92) 7.36% 10 Years 8.66 5 Years -5.55 1 Year -2.84 CLASS B SHARES Inception (5/15/01) -0.23% 1 Year -2.89 CLASS C SHARES Inception (5/15/01) -0.55% 1 Year 1.11 ================================================================================ CUMULATIVE TOTAL RETURNS 6 months ended 8/31/05, excluding applicable sales charges Class A Shares 13.12% Class B Shares 12.73 Class C Shares 12.71 - -------------------------------------------------------------------------------- THE PERFORMANCE DATA QUOTED REPRESENT PAST PERFORMANCE AND CANNOT GUARANTEE COMPARABLE FUTURE RESULTS; CURRENT PERFORMANCE MAY BE LOWER OR HIGHER.

AIM ADVANTAGE HEALTH SCIENCES FUND APPROVAL OF INVESTMENT ADVISORY AGREEMENT AND SUMMARY OF INDEPENDENT WRITTEN FEE EVALUATION The Board of Trustees of AIM Counselor Series Trust (the "Board") oversees the management of AIM Advantage Health Sciences Fund (the "Fund") and, as required by law, determines annually whether to approve the continuance of the Fund's advisory agreement with A I M Advisors, Inc. ("AIM"). Based upon the recommendation of the Investments Committee of the Board, which is comprised solely of independent trustees, at a meeting held on June 30, 2005, the Board, including all of the independent trustees, approved the continuance of the advisory agreement (the "Advisory Agreement") between the Fund and AIM for another year, effective July 1, 2005. The Board considered the factors discussed below in evaluating the fairness and reasonableness of the Advisory Agreement at the meeting on June 30, 2005 and as part of the Board's ongoing oversight of the Fund. In their deliberations, the Board and the independent trustees did not identify any particular factor that was controlling, and each trustee attributed different weights to the various factors. One of the responsibilities of the Senior Officer of the Fund, who is independent of AIM and AIM's affiliates, is to manage the process by which the Fund's proposed management fees are negotiated to ensure that they are negotiated in a manner which is at arm's length and reasonable. To that end, the Senior Officer must either supervise a competitive bidding process or prepare an independent written evaluation. The Senior Officer has recommended an independent written evaluation in lieu of a competitive bidding process and, upon the direction of the Board, has prepared such an independent written evaluation. Such written evaluation also considered certain of the factors discussed below. In addition, as discussed below, the Senior Officer made certain recommendations to the Board in connection with such written evaluation. The discussion below serves as a summary of the Senior Officer's independent written evaluation and recommendations to the Board in connection therewith, as well as a discussion of the material factors and the conclusions with respect thereto that formed the basis for the Board's approval of the Advisory Agreement. After consideration of all of the factors below and based on its informed business judgment, the Board determined that the Advisory Agreement is in the best interests of the Fund and its shareholders and that the compensation to AIM under the Advisory Agreement is fair and reasonable and would have been obtained through arm's length negotiations. .. The nature and extent of the advisory services to be provided by AIM. The Board reviewed the services to be provided by AIM under the Advisory Agreement. Based on such review, the Board concluded that the range of services to be provided by AIM under the Advisory Agreement was appropriate and that AIM currently is providing services in accordance with the terms of the Advisory Agreement. .. The quality of services to be provided by AIM. The Board reviewed the credentials and experience of the officers and employees of AIM who will provide investment advisory services to the Fund. In reviewing the qualifications of AIM to provide investment advisory services, the Board reviewed the qualifications of AIM's investment personnel and considered such issues as AIM's portfolio and product review process, various back office support functions provided by AIM and AIM's equity and fixed income trading operations. Based on the review of these and other factors, the Board concluded that the quality of services to be provided by AIM was appropriate and that AIM currently is providing satisfactory services in accordance with the terms of the Advisory Agreement. .. The performance of the Fund relative to comparable funds. The Board reviewed the performance of the Fund during the past one, three and five calendar years against the performance of funds advised by other advisors with investment strategies comparable to those of the Fund. The Board noted that the Fund's performance in such periods was below the median performance of such comparable funds. The Board also noted that AIM began serving as investment advisor to the Fund in November 2003. The Board noted that AIM has recently made changes to the Fund's portfolio management team, which appear to be producing encouraging early results but need more time to be evaluated before a conclusion can be made that the changes have addressed the Fund's under-performance. Based on this review, the Board concluded that no changes should be made to the Fund and that it was not necessary to change the Fund's portfolio management team at this time. .. The performance of the Fund relative to indices. The Board reviewed the performance of the Fund during the past one, three and five calendar years against the performance of the Lipper Health/Biotech Fund Index. The Board noted that the Fund's performance in such periods was below the performance of such Index. The Board also noted that AIM began serving as investment advisor to the Fund in November 2003. The Board noted that AIM has recently made changes to the Fund's portfolio management team, which appear to be producing encouraging early results but need more time to be evaluated before a conclusion can be made that the changes have addressed the Fund's under-performance. Based on this review, the Board concluded that no changes should be made to the Fund and that it was not necessary to change the Fund's portfolio management team at this time. .. Meeting with the Fund's portfolio managers and investment personnel. With respect to the Fund, the Board is meeting periodically with such Fund's portfolio managers and/or other investment personnel and believes that such individuals are competent and able to continue to carry out their responsibilities under the Advisory Agreement. .. Overall performance of AIM. The Board considered the overall performance of AIM in providing investment advisory and portfolio administrative services to the Fund and concluded that such performance was satisfactory. .. Fees relative to those of clients of AIM with comparable investment strategies. The Board noted that AIM does not serve as an advisor to other mutual funds or other clients with investment strategies comparable to those of the Fund. .. Fees relative to those of comparable funds with other advisors. The Board reviewed the advisory fee rate for the Fund under the Advisory Agreement. The Board noted that the Fund's advisory fee is structured as a fulcrum fee, with a base component and a performance adjustment component. The Board compared effective contractual advisory fee rates at a common asset level and noted that the Fund's rate was above the median rate of the funds advised by other advisors with investment strategies comparable to those of the Fund that the Board reviewed. The Board noted that none of the advisory fees for these other funds were structured as fulcrum fees. The Board noted that AIM has agreed to waive advisory fees of the Fund, as discussed below. Based on this review, the Board concluded that the advisory fee rate for the Fund under the Advisory Agreement was fair and reasonable. .. The Board noted that AIM has contractually agreed to waive advisory fees to the extent necessary such that the advisory fee AIM receives does not exceed an annual base management fee of 1.25%, subject to a maximum annual performance adjustment upward or downward of 0.75%, through June 30, 2006. As a result of this waiver, the Board noted that the net advisory fees are limited to a maximum of 2.00% and a minimum of 0.50%. The Board considered the contractual nature of this fee waiver and noted that it remains in effect until June 30, 2006. The Board considered the effect this fee waiver would have on the Fund's estimated expenses and concluded that the levels of fee waivers/expense limitations for the Fund were fair and reasonable. .. Breakpoints and economies of scale. The Board reviewed the structure of the Fund's advisory fee under the Advisory Agreement, noting that it does not include any breakpoints. The Board considered whether it would be appropriate to add advisory fee breakpoints for the Fund or whether, due to the nature of the Fund and the advisory fee structures of comparable funds, it was reasonable to structure the advisory fee without breakpoints. Based on this review, the Board concluded that it was not necessary to add advisory fee breakpoints to the Fund's advisory fee schedule. The Board reviewed the level of the Fund's advisory fees, and noted that such fees, as a percentage of the Fund's net assets, would remain constant under the Advisory Agreement because the Advisory Agreement does not include any breakpoints. The Board concluded that the Fund's fee levels under the Advisory Agreement therefore would not reflect economies of scale. AIM ADVANTAGE HEALTH SCIENCES FUND .. Investments in affiliated money market funds. The Board also took into account the fact that uninvested cash and cash collateral from securities lending arrangements (collectively, "cash balances") of the Fund may be invested in money market funds advised by AIM pursuant to the terms of an SEC exemptive order. The Board found that the Fund may realize certain benefits upon investing cash balances in AIM advised money market funds, including a higher net return, increased liquidity, increased diversification or decreased transaction costs. The Board also found that the Fund will not receive reduced services if it invests its cash balances in such money market funds. The Board noted that, to the extent the Fund invests in affiliated money market funds, AIM has voluntarily agreed to waive a portion of the advisory fees it receives from the Fund attributable to such investment. The Board further determined that the proposed securities lending program and related procedures with respect to the lending Fund is in the best interests of the lending Fund and its respective shareholders. The Board therefore concluded that the investment of cash collateral received in connection with the securities lending program in the money market funds according to the procedures is in the best interests of the lending Fund and its respective shareholders. .. Independent written evaluation and recommendations of the Fund's Senior Officer. The Board noted that, upon their direction, the Senior Officer of the Fund, who is independent of AIM and AIM's affiliates, had prepared an independent written evaluation in order to assist the Board in determining the reasonableness of the proposed management fees of the AIM Funds, including the Fund. The Board noted that the Senior Officer's written evaluation had been relied upon by the Board in this regard in lieu of a competitive bidding process. In determining whether to continue the Advisory Agreement for the Fund, the Board considered the Senior Officer's written evaluation and the recommendation made by the Senior Officer to the Board that the Board consider implementing a process to assist them in more closely monitoring the performance of the AIM Funds. The Board concluded that it would be advisable to implement such a process as soon as reasonably practicable. .. Profitability of AIM and its affiliates. The Board reviewed information concerning the profitability of AIM's (and its affiliates') investment advisory and other activities and its financial condition. The Board considered the overall profitability of AIM, as well as the profitability of AIM in connection with managing the Fund. The Board noted that AIM's operations remain profitable, although increased expenses in recent years have reduced AIM's profitability. Based on the review of the profitability of AIM's and its affiliates' investment advisory and other activities and its financial condition, the Board concluded that the compensation to be paid by the Fund to AIM under its Advisory Agreement was not excessive. .. Benefits of soft dollars to AIM. The Board considered the benefits realized by AIM as a result of brokerage transactions executed through "soft dollar" arrangements. Under these arrangements, brokerage commissions paid by the Fund and/or other funds advised by AIM are used to pay for research and execution services. This research is used by AIM in making investment decisions for the Fund. The Board concluded that such arrangements were appropriate. .. AIM's financial soundness in light of the Fund's needs. The Board considered whether AIM is financially sound and has the resources necessary to perform its obligations under the Advisory Agreement, and concluded that AIM has the financial resources necessary to fulfill its obligations under the Advisory Agreement. .. Historical relationship between the Fund and AIM. In determining whether to continue the Advisory Agreement for the Fund, the Board also considered the prior relationship between AIM and the Fund, as well as the Board's knowledge of AIM's operations, and concluded that it was beneficial to maintain the current relationship, in part, because of such knowledge. The Board also reviewed the general nature of the non-investment advisory services currently performed by AIM and its affiliates, such as administrative, transfer agency and distribution services, and the fees received by AIM and its affiliates for performing such services. In addition to reviewing such services, the trustees also considered the organizational structure employed by AIM and its affiliates to provide those services. Based on the review of these and other factors, the Board concluded that AIM and its affiliates were qualified to continue to provide non-investment advisory services to the Fund, including administrative, transfer agency and distribution services, and that AIM and its affiliates currently are providing satisfactory non-investment advisory services. .. Other factors and current trends. In determining whether to continue the Advisory Agreement for the Fund, the Board considered the fact that AIM, along with others in the mutual fund industry, is subject to regulatory inquiries and litigation related to a wide range of issues. The Board also considered the governance and compliance reforms being undertaken by AIM and its affiliates, including maintaining an internal controls committee and retaining an independent compliance consultant, and the fact that AIM has undertaken to cause the Fund to operate in accordance with certain governance policies and practices. The Board concluded that these actions indicated a good faith effort on the part of AIM to adhere to the highest ethical standards, and determined that the current regulatory and litigation environment to which AIM is subject should not prevent the Board from continuing the Advisory Agreement for the Fund.

NOTES TO FINANCIAL STATEMENTS August 31, 2005 NOTE 1--SIGNIFICANT ACCOUNTING POLICIES AIM Advantage Health Sciences Fund, formerly INVESCO Advantage Health Sciences Fund, (the "Fund") is a series portfolio of AIM Counselor Series Trust (the "Trust"). The Trust is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end series management investment company consisting of two separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently offers multiple classes of shares. Matters affecting each portfolio or class will be voted on exclusively by the shareholders of such portfolio or class. The assets, liabilities and operations of each portfolio are accounted for separately. Information presented in these financial statements pertains only to the Fund. The Fund's investment objective is to seek capital growth. Under the Trust's organizational documents, each Trustee, officer, employee or other agent of the Trust (including the Trust's investment manager) is indemnified against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts that contain a variety of indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates. The following is a summary of the significant accounting policies followed by the Fund in the preparation of its financial statements. F-7 A. SECURITY VALUATIONS -- Securities, including restricted securities, are valued according to the following policy. A security listed or traded on an exchange (except convertible bonds) is valued at its last sales price as of the close of the customary trading session on the exchange where the security is principally traded, or lacking any sales on a particular day, the security is valued at the closing bid price on that day. Each security traded in the over-the-counter market (but not securities reported on the NASDAQ National Market System) is valued on the basis of prices furnished by independent pricing services, which may be considered fair valued, or market makers. Each security reported on the NASDAQ National Market System is valued at the NASDAQ Official Closing Price ("NOCP") as of the close of the customary trading session on the valuation date or absent a NOCP, at the closing bid price. Futures contracts are valued at the final settlement price set by an exchange on which they are principally traded. Listed options are valued at the mean between the last bid and the ask prices from the exchange on which they are principally traded. Options not listed on an exchange are valued by an independent source at the mean between the last bid and ask prices. For purposes of determining net asset value per share, futures and option contracts generally will be valued 15 minutes after the close of the customary trading session of the New York Stock Exchange ("NYSE"). Investments in open-end registered investment companies and closed-end registered investment companies that do not trade on an exchange are valued at the end of day net asset value per share. Investments in closed-end registered investment companies that trade on an exchange are valued at the last sales price as of the close of the customary trading session on the exchange where the security is principally traded. Debt obligations (including convertible bonds) are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to specific securities, dividend rate, yield, quality, type of issue, coupon rate, maturity, individual trading characteristics and other market data. Short-term obligations having 60 days or less to maturity and commercial paper are valued at amortized cost which approximates market value. Securities for which market prices are not provided by any of the above methods are valued based upon quotes furnished by independent sources and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Foreign securities (including foreign exchange contracts) are converted into U.S. dollar amounts using the applicable exchange rates as of the close of the NYSE. Generally, trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of the close of the respective markets. Events affecting the values of such foreign securities may occur between the times at which the particular foreign market closes and the close of the customary trading session of the NYSE which would not ordinarily be reflected in the computation of the Fund's net asset value. If the event is likely to have affected the closing price of the security, the security will be valued at fair value in good faith using procedures approved by the Board of Trustees. Adjustments to closing prices to reflect fair value may also be based on a screening process of an independent pricing service to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. Foreign securities meeting the approved degree of certainty that the price is not reflective of current market value will be priced at the indication of fair value from the independent pricing service. Multiple factors may be considered by the independent pricing service in determining adjustments to reflect fair value and may include information relating to sector indices, ADRs and domestic and foreign index futures. Securities for which market quotations are not readily available or are unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust's officers following procedures approved by the Board of Trustees. Issuer specific events, market trends, bid/ask quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security's fair value. B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income is recorded on the accrual basis from settlement date. Dividend income is recorded on the ex-dividend date. Bond premiums and discounts are amortized and/or accreted for financial reporting purposes. Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of realized and unrealized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the realized and unrealized net gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund's net asset value and, accordingly, they reduce the Fund's total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and Statement of Changes in Net Assets, or the net investment income per share and ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the advisor. The Fund allocates income and realized and unrealized capital gains and losses to a class based on the relative net assets of each class. Cash and cash equivalents in the Statement of Cash Flows are comprised of cash and investments in affiliated money market funds for the purpose of investing daily available cash balances. C. COUNTRY DETERMINATION -- For the purposes of making investment selection decisions and presentation in the Schedule of Investments, AIM may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer's securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be United States of America unless otherwise noted. D. DISTRIBUTIONS -- Distributions from income and net realized capital gain, if any, are generally paid annually and recorded on ex-dividend date. The Fund may elect to use a portion of the proceeds from redemptions as distributions for federal income tax purposes. F-8 E. FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code necessary to qualify as a regulated investment company and, as such, will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) which is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements. F. EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular class of the Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets. G. CASH AND CASH EQUIVALENTS -- Cash and cash equivalents in the Statement of Cash Flows are comprised of cash and investments in affiliated money market funds for the purpose of investing daily available cash balances. H. SECURITIES SOLD SHORT -- The Fund may enter into short sales of securities which it concurrently holds (against the box) or for which it holds no corresponding position (naked). Securities sold short represent a liability of the Fund to acquire specific securities at prevailing market prices at a future date in order to satisfy the obligation to deliver the securities sold. The liability is recorded on the books of the Fund at the market value of the common stock determined each day in accordance with the procedures for security valuations disclosed in "A" above. The Fund will incur a loss if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. The Fund realizes a gain if the price of the security declines between those dates. The Fund is required to segregate cash or securities as collateral in margin accounts at a level that is equal to the obligation to the broker who delivered such securities to the buyer on behalf of the Fund. The short stock rebate presented in the Statement of Operations represents the net income earned on short sale proceeds held on deposit with the broker and margin interest earned or incurred on short sale transactions. The Fund may also earn or incur margin interest on short sales transactions. Margin interest is the income earned (or expense incurred) as a result of the market value of securities sold short being less than (or greater than) the proceeds received from the short sales. I. FOREIGN CURRENCY TRANSLATIONS -- Foreign currency is valued at the close of the NYSE based on quotations posted by banks and major currency dealers. Portfolio securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts at date of valuation. Purchases and sales of portfolio securities (net of foreign taxes withheld on disposition) and income items denominated in foreign currencies are translated into U.S. dollar amounts on the respective dates of such transactions. The Fund does not separately account for the portion of the results of operations resulting from changes in foreign exchange rates on investments and the fluctuations arising from changes in market prices of securities held. The combined results of changes in foreign exchange rates and the fluctuation of market prices on investments (net of estimated foreign tax withholding) are included with the net realized and unrealized gain or loss from investments in the Statement of Operations. Reported net realized foreign currency gains or losses arise from (i) sales of foreign currencies, (ii) currency gains or losses realized between the trade and settlement dates on securities transactions, and (iii) the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign currency gains and losses arise from changes in the fair values of assets and liabilities, other than investments in securities at fiscal period end, resulting from changes in exchange rates. J. FOREIGN CURRENCY CONTRACTS -- A foreign currency contract is an obligation to purchase or sell a specific currency for an agreed-upon price at a future date. The Fund may enter into a foreign currency contract to attempt to minimize the risk to the Fund from adverse changes in the relationship between currencies. The Fund may also enter into a foreign currency contract for the purchase or sale of a security denominated in a foreign currency in order to "lock in" the U.S. dollar price of that security. The Fund could be exposed to risk if counterparties to the contracts are unable to meet the terms of their contracts or if the value of the foreign currency changes unfavorably. K. COVERED CALL OPTIONS -- The Fund may write and buy call options, including securities index options. Options written by the Fund normally will have expiration dates between three and nine months from the date written. The exercise price of a call option may be below, equal to, or above the current market value of the underlying security at the time the option is written. When the Fund writes a call option, an amount equal to the premium received by the Fund is recorded as an asset and an equivalent liability. The amount of the liability is subsequently "marked-to-market" to reflect the current market value of the option written. The current market value of a written option is the mean between the last bid and asked prices on that day. If a written call option expires on the stipulated expiration date, or if the Fund enters into a closing purchase transaction, the Fund realizes a gain (or a loss if the closing purchase transaction exceeds the premium received when the option was written) without regard to any unrealized gain or loss on the underlying security, and the liability related to such option is extinguished. If a written option is exercised, the Fund realizes a gain or a loss from the sale of the underlying security and the proceeds of the sale are increased by the premium originally received. A risk in writing a call option is that the Fund gives up the opportunity for profit if the market price of the security increases and the option is exercised. A call option gives the purchaser of such option the right to buy, and the writer (the Fund) the obligation to sell, the underlying security at the stated exercise price during the option period. The purchaser of a call option has the right to acquire the security which is the subject of the call option at any time during the option period. During the option period, in return for the premium paid by the purchaser of the option, the Fund has given up the opportunity for capital appreciation above the exercise price should the market price of the underlying security increase, but has retained the risk of loss should the price of the underlying security decline. During the option period, the Fund may be required at any time to deliver the underlying security against payment of the exercise price. This obligation is terminated upon the expiration of the option period or at such earlier time at which the Fund effects a closing purchase transaction by purchasing (at a price which may be higher than that received when the call option was written) a call option identical to the one originally written. An option on a securities index gives the holder the right to receive a cash "exercise settlement amount" equal to the difference between the exercise price of the option and the value of the underlying stock index on the exercise date, multiplied by a fixed "index multiplier." A securities index fluctuates with changes in the market values of the securities included in the index. In the purchase of securities index options, the principal risk is that the premium and transaction costs paid by the Fund in purchasing an option will be lost if the changes in the level of the index do not exceed the cost of the option. In writing securities index options, the principal risk is that the Fund could bear a loss on the options that would be only partially offset (or not offset at all) by the increased value or reduced cost of hedged securities. Moreover, in the event the Fund was unable to close an option it had written, it might be unable to sell the securities used as cover. F-9 L. PUT OPTIONS -- The Fund may purchase put options. By purchasing a put option, the Fund obtains the right (but not the obligation) to sell the option's underlying instrument at a fixed strike price. In return for this right, the Fund pays an option premium. The option's underlying instrument may be a security or a futures contract. Put options may be used by the Fund to hedge securities it owns by locking in a minimum price at which the Fund can sell. If security prices fall, the put option could be exercised to offset all or a portion of the Fund's resulting losses. At the same time, because the maximum the Fund has at risk is the cost of the option, purchasing put options does not eliminate the potential for the Fund to profit from an increase in the value of the securities hedged. A risk in buying an option is that the Fund pays a premium whether or not the option is exercised. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold. M. VENTURE CAPITAL INVESTMENTS -- The Fund has invested in non-publicly traded companies, some of which are in the startup or development stages. These investments are inherently risky, as the markets for the technologies or products these companies are developing are typically in the early stages and may never materialize. The Fund could lose its entire investment in these companies. These investments are valued at fair value as determined in good faith in accordance with procedures approved by the Board of Trustees. Investments in privately held venture capital securities are illiquid. N. COLLATERAL -- To the extent the Fund has pledged or segregated a security as collateral and that security is subsequently sold, it is the Fund's practice to replace such collateral no later than the next business day. This practice does not apply to securities pledged as collateral for securities lending transactions. NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES The Trust has entered into a master investment advisory agreement with A I M Advisors, Inc. ("AIM"). Under the terms of the investment advisory agreement, the Fund pays a base management fee calculated at the annual rate of 1.50% of the Fund's average daily net assets. The base management fee will be adjusted on a monthly basis by a calculated rate ("Fee Adjustment Rate") (i) upward at the rate of 0.20%, on a pro rata basis, for each percentage point the investment performance of the Class A shares of the Fund for the previous 12 month period ("Performance Period") exceeds the sum of 2.00% plus the investment record of the Morgan Stanley Health Care Product Index for the Performance Period, but shall be capped at 2.50% of the Fund's average daily net assets for the fiscal period, or (ii) downward at the rate of 0.20%, on a pro rata basis, for each percentage point the investment record of the Morgan Stanley Health Care Product Index for the Performance Period less 2.00% exceeds the investment performance of the Class A shares of the Fund for the Performance Period, but shall be no less than 0.50% of the average daily net assets for the fiscal period. After the Fee Adjustment Rate is determined, AIM will determine the dollar amount of additional fees or fee reductions to be accrued for each day of a month by multiplying the Fee Adjustment Rate by the average daily net assets of the Class A shares of the Fund during the Performance Period and dividing the number by the number of days in the Performance Period. The management fee, as adjusted, is accrued daily and paid monthly. AIM has contractually agreed to waive advisory fees to the extent necessary such that the advisory fee AIM receives does not exceed an annual base management fee of 1.25%, subject to an annual maximum of 0.75% performance adjustment upward or downward, through June 30, 2006 calculated in the same manner as described above. As a result of this waiver, the net advisory fees are limited to a maximum of 2.00% and a minimum of 0.50%. Under the terms of a master sub-advisory agreement between AIM and INVESCO Institutional (N.A.), Inc. ("INVESCO"), AIM paid INVESCO 40% of the fee paid by the Fund to AIM. This sub-advisory agreement expired on September 30, 2004. Further, AIM has voluntarily agreed to waive advisory fees of the Fund in the amount of 25% of the advisory fee AIM receives from the affiliated money market funds on investments by the Fund in such affiliated money market funds (excluding investments made in affiliated money market funds with cash collateral from securities loaned by the fund). AIM is also voluntarily waiving a portion of the advisory fee payable by the Fund equal to the difference between the income earned from investing in the affiliated money market fund and the hypothetical income earned from investing in an appropriate comparative benchmark. Voluntary fee waivers or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors. Under the terms of the advisory agreement, the Fund is not permitted to pay management fees on those assets of the Fund that are invested in other funds advised by AIM. For the year ended August 31, 2005, AIM waived fees and/or reimbursed expenses in the amount of $386,451. At the request of the Trustees of the Trust, AMVESCAP PLC ("AMVESCAP") agreed to reimburse expenses incurred by the Fund in connection with market timing matters in the AIM Funds, which may include legal, audit, shareholder reporting, communications and trustee expenses. These expenses along with the related expense reimbursement, are included in the Statement of Operations. For the year ended August 31, 2005, AMVESCAP reimbursed expenses of the Fund in the amount of $32,412. The Fund, pursuant to a master administrative services agreement with AIM, has agreed to pay AIM for certain administrative costs incurred in providing accounting services to the Fund. Pursuant to such agreement, for the year ended August 31, 2005, AIM was paid $50,000. The Fund, pursuant to a transfer agency and service agreement, has agreed to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer agency and shareholder services to the Fund and reimburse AISI for certain expenses incurred by AISI in the course of providing such services. AISI may make payments to intermediaries that provide omnibus account services, sub-accounting services and/or networking services. For the year ended August 31, 2005, the Fund paid AISI $296,166. The Trust has entered into master distribution agreements with A I M Distributors, Inc. ("ADI") to serve as the distributor for the Class A, Class B and Class C shares of the Fund. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund's Class A, Class B and Class C shares (collectively the "Plans"). The Fund, pursuant to the Plans, pays ADI compensation at the annual rate of 0.25% of the Fund's average daily net assets of Class A shares and 1.00% of the average daily net assets of Class B and Class C shares. Prior to July 1, 2005, the Fund paid ADI 0.35% of the average daily net assets of Class A shares. Of these amounts, up to 0.25% of the average daily net assets of the Class A, Class B or Class C shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such classes. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. National Association of Securities Dealers ("NASD") Rules also impose a cap on the total sales charges, including asset-based sales charges that may be paid by any class of shares of the Fund. Pursuant to the Plans, for the year ended August 31, 2005, the Class A, Class B and Class C shares paid $510,831, $10,938 and $3,553, respectively. Front-end sales commissions and contingent deferred sales charges ("CDSC") (collectively the "sales charges") are not recorded as expenses of the Fund. Front-end sales commissions are deducted from proceeds from the sales of Fund shares prior to investment in Class A shares of the Fund. CDSC are deducted from redemption proceeds prior to remittance to the shareholder. For the year ended August 31, 2005, ADI advised the Fund that it retained $5,474 in front-end sales F-10 commissions from the sale of Class A shares and $1, $2,203 and $49 from Class A, Class B and Class C shares, respectively, for CDSC imposed upon redemptions by shareholders. Certain officers and trustees of the Trust are officers and directors of AIM, AISI, INVESCO and/or ADI. NOTE 3--INVESTMENTS IN AFFILIATES The Fund is permitted, pursuant to an exemptive order from the Securities and Exchange Commission ("SEC"), to invest daily available cash balances and cash collateral from securities lending transactions in affiliated money market funds. The Fund and the money market fund below have the same investment advisor and therefore, are considered to be affiliated.

F-11 NOTE 4--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS The Fund is permitted to purchase or sell securities from or to certain other AIM Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment advisor (or affiliated investment advisors), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. Pursuant to these procedures, during the year ended August 31, 2005, the Fund engaged in securities purchases of $3,463,421 and sales of $510,247, which resulted in net realized gains of $111,104. NOTE 5--EXPENSE OFFSET ARRANGEMENT The expense offset arrangement is comprised of transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions. For the year ended August 31, 2005, the Fund received credits from this arrangement, which resulted in the reduction of the Fund's total expenses of $4,028. NOTE 6--TRUSTEES' AND OFFICER'S FEES AND BENEFITS "Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund to pay remuneration to each Trustee and Officer of the Fund who is not an "interested person" of AIM. Trustees have the option to defer compensation payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also include amounts accrued by the Fund to fund such deferred compensation amounts. Those Trustees who defer compensation have the option to select various AIM Funds in which their deferral accounts shall be deemed to be invested. Finally, current Trustees are eligible to participate in a retirement plan that provides for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees who also participate in a retirement plan and receive benefits under such plan. "Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Fund. During the year ended August 31, 2005, the Fund paid legal fees of $4,518 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the Independent Trustees. A member of that firm is a Trustee of the Trust. NOTE 7--BORROWINGS Effective November 1, 2004, the Fund entered into a committed line of credit facility with a syndicate administered by JP Morgan Chase Bank. The Fund may borrow up to the lesser of (i) $225,000,000 (ii) the limits set by its prospectus for borrowings. As amended on August 23, 2005, the Fund may borrow up to the lesser of (i) $255,000,000 or (ii) the limits set by its Prospectus for borrowings. The Fund and other funds advised by AIM which are parties to the line of credit may borrow on a first come, first served basis. The funds which are party to the line of credit are charged a commitment fee of 0.09% on the unused balance of the committed line. During the year ended August 31, 2005, the Fund had average borrowings for the 304 days the borrowings were outstanding, in the amount of $24,000,000 with a weighted average interest rate of 3.54% and interest expense of 707,254. Prior to November 1, 2004, the Fund was a participant in a committed line of credit facility with a syndicate administered by Citibank, N.A. The Fund may borrow up to the lesser of (i) $100,000,000 or (ii) the limits set by its prospectus for borrowings. The Fund and other funds advised by AIM which are parties to the line of credit may borrow on a first come, first served basis. The funds which are party to the line of credit are charged a commitment fee of 0.10% on the unused balance of the committed line. During the year ended August 31, 2005, the Fund had average borrowings for the 61 days the borrowings were outstanding, in the amount of $23,852,459 with a weighted average interest rate of 2.48% and interest expense of $98,893. Pursuant to an exemptive order from the SEC, the Fund may participate in an interfund lending facility that AIM has established for temporary borrowings by the AIM Funds. An interfund loan will be made under this facility only if the loan rate (an average of the rate available on bank loans and the rate available on investments in overnight repurchase agreements) is favorable to both the lending fund and the borrowing fund. A loan will be secured by collateral if the Fund's aggregate borrowings from all sources exceeds 10% of the Fund's total assets. To the extent that the loan is required to be secured by collateral, the collateral is marked to market daily to ensure that the market value is at least 102% of the outstanding principal value of the loan. During the year ended August 31, 2005, the Fund did not borrow or lend under the interfund lending facility. Additionally, the Fund is permitted to temporarily carry a negative or overdrawn balance in its account with SSB, the custodian bank. To compensate the custodian bank for such overdrafts, the overdrawn Fund may either (i) leave funds as a compensating balance in the account so the custodian can be compensated by earning the additional interest; or (ii) compensate by paying the custodian bank at a rate agreed upon by the custodian bank and AIM, not to exceed the rate contractually agreed upon. NOTE 8--PORTFOLIO SECURITIES LOANED The Fund may lend portfolio securities having a market value up to one-third of the Fund's total assets. Such loans are secured by collateral equal to no less than the market value of the loaned securities determined daily. Such collateral will be cash or debt securities issued or guaranteed by the U.S. Government or any of its agencies. Cash collateral received in connection with these loans is invested in short-term money market instruments or affiliated money market funds. It is the Fund's policy to obtain additional collateral from or return excess collateral to the borrower by the end of the next business day, following the valuation date of the securities loaned. Therefore, the value of the collateral held may be temporarily less than the value of the securities on loan. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the securities loaned were to increase and the borrower did not increase the collateral accordingly, and the borrower fails to return the securities. The Fund could also experience delays and costs in gaining access to the collateral. The Fund bears the risk of any deficiency in the amount of the collateral available for return to the borrower due to a loss on the collateral invested. F-12 NOTE 8--PORTFOLIO SECURITIES LOANED-(CONTINUED) At August 31, 2005, securities with an aggregate value of $4,071,724 were on loan to brokers. The loans were secured by cash collateral of $4,085,119 received by the Fund and subsequently invested in an affiliated money market fund. For the year ended August 31, 2005, the Fund received dividends on cash collateral of $6,687 for securities lending transactions, which are net of compensation to counterparties.

TAX COMPONENTS OF NET ASSETS: As of August 31, 2005, the components of net assets on a tax basis were as follows: 2005 ------------------------------------------------------------------ Undistributed appreciation (depreciation)-investments 3,097,025 ------------------------------------------------------------------ Temporary book/tax differences (19,052) ------------------------------------------------------------------ Capital loss carryforward (5,262,663) ------------------------------------------------------------------ Shares of beneficial interest 156,637,305 ------------------------------------------------------------------ Total net assets 154,452,615 ------------------------------------------------------------------ The difference between book-basis and tax-basis unrealized appreciation (depreciation) is due to differences in the timing of recognition of gains and losses on investments for tax and book purposes. The Fund's unrealized appreciation (depreciation) difference is attributable primarily to the deferral of losses on wash sales. The tax-basis unrealized appreciation (depreciation) on investments amount includes appreciation (depreciation) on foreign currencies of $(16,899), remaining proceeds to be received on security buyout of $221,807 and an allowance for doubtful receipts of $70,982. The temporary book/tax differences are a result of timing differences between book and tax recognition of income and/or expenses. The Fund's temporary book/tax differences are the result of the trustee deferral of compensation and retirement plan expenses. Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Fund to utilize. The ability to utilize capital loss carryforward in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions. The Fund utilized $17,835,053 of capital loss carryforward in the current period to offset net realized capital gain for federal income tax purposes. The Fund has a capital loss carryforward as of August 31, 2005 which expires as follows: CAPITAL LOSS EXPIRATION CARRYFORWARD* ----------------------------- August 31, 2011 $5,262,663 ----------------------------- *Capital loss carryforward as of the date listed above is reduced for limitations, if any, to the extent required by the Internal Revenue Code. F-13 NOTE 11--INVESTMENT SECURITIES The aggregate amount of investment securities (other than short-term securities and money market funds) purchased and sold by the Fund during the year ended August 31, 2005 was $222,324,657 and $267,596,799, respectively. The receivable for investments sold is net of an allowance for doubtful receipts of $70,982 for Norian Corp.-Series D, convertible preferred shares. At the request of the Trustee, AIM recovered third party research credits, during the year ended August 31, 2005, in the amount of $37,038. These research credits were recorded as realized gains. UNREALIZED APPRECIATION (DEPRECIATION) OF INVESTMENT SECURITIES ON A TAX BASIS - --------------------------------------------------------------------------------- Aggregate unrealized appreciation of: Investment securities $ 32,959,013 - --------------------------------------------------------------------------------- Securities sold short 160,360 - --------------------------------------------------------------------------------- Aggregate unrealized (depreciation) of: Investment securities (28,699,733) - --------------------------------------------------------------------------------- Securities sold short (1,456,541) - --------------------------------------------------------------------------------- Net unrealized appreciation (depreciation) of investment securities (2,963,099) - --------------------------------------------------------------------------------- Cost of investments for tax purposes is $175,908,522. Proceeds from securities sold short for investment purposes are $8,515,039. NOTE 12--RECLASSIFICATION OF PERMANENT DIFFERENCES Primarily as a result of differing book/tax treatment of foreign currency transactions, redomestication costs, certain dividends on short sales and net operating losses, on August 31, 2005, undistributed net investment income (loss) was increased by $2,284,028, undistributed net realized gain (loss) was decreased by $19,516 and shares of beneficial interest decreased by $2,264,512. This reclassification had no effect on the net assets of the Fund. NOTE 13--SHARE INFORMATION The Fund currently offers three different classes of shares: Class A shares, Class B shares and Class C shares. Class A shares are sold with a front-end sales charge. Class B shares and Class C shares are sold with CDSC. Under certain circumstances, Class A shares are subject to CDSC. Generally, Class B shares will automatically convert to Class A shares eight years after the end of the calendar month of purchase.

NOTE 15--LEGAL PROCEEDINGS Terms used in the Legal Proceedings Note are defined terms solely for the purpose of this note. SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the distributor of the retail AIM Funds) reached final settlements with certain regulators, including the Securities and Exchange Commission ("SEC"), the New York Attorney General and the Colorado Attorney General, to resolve civil enforcement actions and/or investigations related to market timing and related activity in the AIM Funds, including those formerly advised by IFG. As part of the settlements, a $325 million fair fund ($110 million of which is civil penalties) has been created to compensate shareholders harmed by market timing and related activity in funds formerly advised by IFG. Half of this amount has already been paid to the fair fund pursuant to the terms of the settlement with the remainder due December 31, 2005. Additionally, AIM and ADI created a $50 million fair fund ($30 million of which is civil penalties) to compensate shareholders harmed by market timing and related activity in funds advised by AIM, which was done pursuant to the terms of the settlement. These two fair funds may increase as a result of contributions from third parties who reach final settlements with the SEC or other regulators to resolve allegations of market timing and/or late trading that also may have harmed applicable AIM Funds. These two fair funds will be distributed in accordance with a methodology to be determined by AIM's independent distribution consultant, in consultation with AIM and the independent trustees of the AIM Funds and acceptable to the staff of the SEC. As the methodology is unknown at the present time, management of AIM and the Fund are unable to estimate the impact, if any, that the distribution of these two fair funds may have on the Fund or whether such distribution will have an impact on the Fund's financial statements in the future. At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"), the parent company of IFG and AIM, has agreed to reimburse expenses incurred by the AIM Funds related to market timing matters. F-17 NOTE 15--LEGAL PROCEEDINGS-(CONTINUED) REGULATORY INQUIRIES AND PENDING LITIGATION IFG, AIM, ADI and/or related entities and individuals have received inquiries from numerous regulators in the form of subpoenas or other oral or written requests for information and/or documents related to one or more of the following issues, some of which concern one or more AIM Funds: market timing activity, late trading, fair value pricing, excessive or improper advisory and/or distribution fees, mutual fund sales practices, including revenue sharing and directed-brokerage arrangements, investments in securities of other registered investment companies, contractual plans, issues related to Section 529 college savings plans and procedures for locating lost securityholders. IFG, AIM and ADI are providing full cooperation with respect to these inquiries. As described more fully below, the AIM Funds, IFG, AIM, ADI and/or related entities and individuals are defendants in numerous civil lawsuits related to one or more of these issues. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, AIM and/or related entities and individuals in the future. On April 12, 2005, the Attorney General of the State of West Virginia ("WVAG") filed a civil lawsuit against AIM, IFG and ADI, as well as numerous unrelated mutual fund complexes and financial institutions. None of the AIM Funds has been named as a defendant in this lawsuit. The WVAG complaint, filed in the Circuit Court of Marshall County, West Virginia [Civil Action No. 05-C-81], alleges, in substance, that AIM, IFG and ADI engaged in unfair competition and/or unfair or deceptive trade practices by failing to disclose in the prospectuses for the AIM Funds, including those formerly advised by IFG, that they had entered into certain arrangements permitting market timing of such Funds. As a result of the foregoing, the WVAG alleges violations of W. Va. Code (S) 46A-1-101, et seq. (the West Virginia Consumer Credit and Protection Act). The WVAG complaint is seeking, among other things, injunctive relief, civil monetary penalties and a writ of quo warranto against the defendants. If AIM is unsuccessful in its defense of the WVAG lawsuit, it could be barred from serving as an investment advisor for any investment company registered under the Investment Company Act of 1940, as amended (a "registered investment company"). Such results could affect the ability of AIM or any other investment advisor directly or indirectly owned by AMVESCAP, from serving as an investment advisor to any registered investment company, including the Fund. The Fund has been informed by AIM that, if these results occur, AIM will seek exemptive relief from the SEC to permit it to continue to serve as the Fund's investment advisor. There is no assurance that such exemptive relief will be granted. On July 7, 2005, the Supreme Court of West Virginia ruled in the context of a separate lawsuit that the WVAG does not have authority pursuant to W. Va. Code Section 46A-6-104 of the West Virginia Consumer Credit and Protection Act to bring an action based upon conduct that is ancillary to the purchase or sale of securities. AIM intends to seek dismissal of the WVAG's lawsuit against it, IFG and ADI in light of this ruling. On August 30, 2005, the West Virginia Office of the State Auditor--Securities Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of Right to Hearing to AIM and ADI. The WVASC makes findings of fact that essentially mirror the WVAG's allegations mentioned above and conclusions of law to the effect that AIM and ADI violated the West Virginia securities laws. The WVASC orders AIM and ADI to cease any further violations and seeks to impose monetary sanctions to be determined by the Commissioner. AIM and ADI have the right to contest the WVASC's findings and conclusions, which they intend to do. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or related entities and individuals, depending on the lawsuit, alleging: . that the defendants permitted improper market timing and related activity in the AIM Funds; . that certain AIM Funds inadequately employed fair value pricing; . that the defendants charged excessive advisory and/or distribution fees and failed to pass on to shareholders the perceived savings generated by economies of scale and that the defendants adopted unlawful distribution plans; . that the defendants breached their fiduciary duties by charging distribution fees while AIM Funds and/or specific share classes were closed generally to new investors and/or while other share classes of the same AIM Fund were not charged the same distribution fees; . that the defendants improperly used the assets of the AIM Funds to pay brokers to aggressively promote the sale of the AIM Funds over other mutual funds and that the defendants concealed such payments from investors by disguising them as brokerage commissions; and . that the defendants breached their fiduciary duties by failing to ensure that the AIM Funds participated in class action settlements in which they were eligible to participate (this lawsuit was dismissed by the Court on August 12, 2005). These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and ERISA, negligence, breach of fiduciary duty and/or breach of contract. These lawsuits seek remedies that include, depending on the lawsuit, damages, restitution, injunctive relief, imposition of a constructive trust, removal of certain directors and/or employees, various corrective measures under ERISA, rescission of certain AIM Funds' advisory agreements and/or distribution plans and recovery of all fees paid, an accounting of all fund-related fees, commissions and soft dollar payments, restitution of all commissions and fees paid, and prospective relief in the form of reduced fees. All lawsuits based on allegations of market timing, late trading and related activity have been transferred to the United States District Court for the District of Maryland. On August 25, 2005, the Court issued rulings on the common issues of law presented in defendants' motions to dismiss the shareholder class and derivative complaints. These rulings were issued in the context of the Janus lawsuits, but the Court's legal determinations apply at the omnibus level to all cases within his track, including the AIM and IFG cases. The Court dismissed for failure to make pre-suit demand on the fund board all derivative causes of action but one: the excessive fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940 Act"), as to which the demand requirement does not apply. The Court dismissed all claims asserted in the class complaint but two: (i) the securities fraud claims under Section 10(b) of the Securities Exchange Act of 1934, and (ii) the excessive fee claim under Section 36(b) of the 1940 Act. In addition, the Court limited plaintiffs' potential recovery on the 36(b) claim to fees attributable to timing assets, as opposed to all fees on funds in which any timing occurred. The question whether the duplicative Section 36(b) claim properly belongs in the derivative complaint or in the class action complaint will be decided at a later date. The Court will subsequently issue an order applying his legal rulings to the allegations in the AIM and IFG complaints. F-18 NOTE 15--LEGAL PROCEEDINGS-(CONTINUED) At the present time, management of AIM and the Fund are unable to estimate the impact, if any, that the outcome of the Regulatory Inquiries and Pending Litigation described above may have on AIM, ADI or the Fund. * * * * * * * * * * * * * * * * As a result of the matters discussed above, investors in the AIM Funds might react by redeeming their investments. This might require the AIM Funds to sell investments to provide for sufficient liquidity and could also have an adverse effect on the investment performance of the AIM Funds. F-19 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of AIM Advantage Health Sciences Fund: In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations, of changes in net assets and of cash flows and the financial highlights present fairly, in all material respects, the financial position of AIM Advantage Health Sciences Fund, formerly known as INVESCO Advantage Health Sciences Fund, (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, the cash flows for the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. /S/ PRICEWATERHOUSECOOPERS LLP October 19, 2005 Houston, Texas F-20 TRUSTEES AND OFFICERS As of August 31, 2005 The address of each trustee and officer of AIM Counselor Series Trust (the "Trust"), is 11 Greenway Plaza, Suite 100, Houston, Texas 77046.

Most equity indexes, both domestic and international, ended up producing double-digit returns for the fiscal year. For a discussion of how market conditions affected your Fund and how the Fund was managed during the fiscal year, please turn to Page 3. ADDITIONAL INFORMATION IN THIS REPORT ROBERT H. GRAHAM We would like to call your attention to two new elements in this report on your Fund. First, on Page 2, is a letter from Bruce Crockett, the independent Chair of the Board of Trustees of the AIM Funds. We first introduced you to Mr. Crockett in the annual report on your Fund dated September 30, 2004. Mr. Crockett has been on our Funds' Board since 1992; he assumed his responsibilities as Chair in October 2004. [WILLIAMSON PHOTO] Mr. Crockett has expressed an interest in keeping shareholders informed of the work of the Board regularly via letters in the Fund reports. We certainly consider this a valuable addition to the reports. The Board is charged with looking out for the interests of shareholders, and Mr. Crockett's letter provides insight into some of the many issues the Board addresses in governing your Fund. MARK H. WILLIAMSON One of the most important decisions the Board makes each year is whether to approve the advisory agreement your Fund has with AIM. Essentially, this agreement hires AIM to manage the assets in your Fund. A discussion of the factors the Board considered in reviewing the agreement is the second new element in the report, and we encourage you to read it. It appears on Pages 9 and 10. Further information about the markets, your Fund, and investing in general is always available on our widely acclaimed Web site, AIMinvestments.com. We invite you to visit it frequently. We at AIM remain committed to building solutions to help you meet your investment goals. We thank you for your continued participation in AIM Investments --REGISTERED TRADEMARK--.

[CROCKETT PHOTO] At our most recent meeting in June 2005, your Board approved voluntary fee reductions from A I M Advisors, Inc. (AIM) that save shareholders approximately $20.8 million annually, based on asset levels as of March 31, 2005. The majority of these expense reductions, which took effect July 1, 2005, will be achieved by a permanent reduction to 0.25% of the Rule 12b-1 fees on Class A and Class A3 shares of those AIM Funds that previously charged these fees at a higher rate. BRUCE L. CROCKETT Our June meeting, which was the culmination of more than two and one-half months of review and discussions, took place over a three-day period. The meeting included your Board's annual comprehensive evaluation of each fund's advisory agreement with AIM. After this evaluation, in which questions about fees, performance and operations were addressed by AIM, your Board approved all advisory agreements for the year beginning July 1, 2005. You can find information on the factors considered and conclusions reached by your Board in its evaluation of each fund's advisory agreement at AIMinvestments.com. (Go to "Products & Performance" and click on "Investment Advisory Agreement Renewals.") The advisory agreement information about your Fund is also included in this annual report on Pages 9 and 10. I encourage you to review it. Together with monitoring fund expenses, fund performance is your Board's priority. Our initial goal is to work with AIM to bring about improvement in every AIM Fund that has been underperforming its category. Your Board has a well-defined process and structure for monitoring all funds and identifying and assisting AIM in improving underperforming funds. Our Investments Committee--which functions along with Audit, Governance, Valuation and Compliance Committees--is the only one of these five standing committees to include all 13 independent Board members. Further, our Investments Committee is divided into three underlying subcommittees, each responsible for, among other things, reviewing the performance, fees and expenses of the funds that have been assigned to it. At subcommittee meetings, held throughout the year, the performance of every AIM Fund is evaluated. If a fund has underperformed its peer group for a meaningful period, we work closely with AIM to discover the causes and help develop the right responses. In some cases, AIM may determine that a change in portfolio management strategy or portfolio managers is required. In other cases, where a fund no longer seems viable, it may be merged with a similar fund, being careful to consider the needs of all shareholders affected by the decision. Following AIM's recommendation and your Board's approval, eight funds were recently merged. Be assured that your Board is working closely with the management of AIM to help you reach your investment goals. Should you or your advisor have questions or comments about the governance of AIM Funds, I invite you to write to me at AIM Investments, AIM Investments Tower, 11 Greenway Plaza, Suite 100, Houston, TX 77046. Your Board looks forward to keeping you informed about the governance of your funds. Sincerely, /s/ BRUCE L. CROCKETT Bruce L. Crockett Independent Chair On Behalf of the Board of Trustees AIM Funds October 13, 2005 2 AIM MULTI-SECTOR FUND MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE - -------------------------------------------------------------------------------- PERFORMANCE SUMMARY We are pleased to report that for the fiscal year ended August 31, 2005, Class A shares of AIM Multi-Sector Fund returned 28.01% at net asset value. Your Fund handily outperformed the S&P 500 Index, which returned 12.55%. The Fund's overweight position in energy stocks was its greatest contributor to its outperformance relative to the broad market. Solid stock selection allowed your Fund to significantly outperform the S&P 500 Index in each of the five sectors in which it invests, as shown in the table on Page 4. - -------------------------------------------------------------------------------- FUND VS.

Fund assets are divided approximately equally among securities of companies in each sector to provide diversification. Fund managers act independently, creating portfolios for each sector that are applications of our best ideas in existing AIM sector funds. Managers use quantitative measures in stock selection combined with insights from fundamental research to determine if a stock has value and strong anticipated growth relative to its peers. We focus on companies that exhibit strong return on capital, cash flow, sustainable growth, and superior business strategies that make them market leaders. In the resulting portfolios, each sector has approximately 20 to 25 holdings. Your Fund is rebalanced annually at fiscal year-end to return the sectors to their approximate equal weightings. We consider selling a stock when we see: .. fundamental deterioration in the company .. more attractive investment opportunities .. inability of the company to capitalize on market opportunity .. a questionable change in management's strategic direction MARKET CONDITIONS AND YOUR FUND Throughout the fiscal year, the economy expanded, driven largely by sustained, robust consumer spending. At its close, inflation (excluding energy) remained modest and payrolls continued to expand. In testimony to Congress in late July, U.S. Federal Reserve Board (the Fed) Chairman Alan Greenspan suggested such trends were likely to continue when he reported that "our baseline outlook for the U.S. economy is one of sustained economic growth and contained inflation pressures." Higher short-term interest rates and rising energy prices were the most significant headwinds for the U.S. economy and the broad stock market. In an effort to ensure that inflation remained contained, the Fed raised its federal funds target rate from 1.50% at the start of the fiscal year to 3.50% at its close. Its actions caused credit card interest rates, for example, to rise for many consumers. Together, these two factors had the potential to crimp consumer spending and slow economic growth. As the fiscal year drew to a close, we began to see signs that historically high energy prices might finally be causing consumers to reduce (Continued On Page 4) - -------------------------------------------------------------------------------- PORTFOLIO COMPOSITION TOP 10 INDUSTRIES* TOP 10 EQUITY HOLDINGS* By sector Energy 21.2% 1.

In late August, Hurricane Katrina disrupted offshore oil and gas production and shut down eight major refineries in the Gulf Coast region, sending oil and gasoline prices higher. We continue to monitor these trends closely. For the fiscal year, all 10 sectors of the S&P 500 Index posted gains. Of the five sectors in which the Fund primarily invests, performance varied widely--from the energy sector's 52% return to the financials sector's 4% return. See the table below for more specific information about the performance of market sectors in which the Fund invests the bulk of its assets. Solid stock selection allowed your Fund to significantly outperform the S&P 500 Index in each of the five sectors in which it invests... All 20 of your Fund's energy-sector holdings contributed positively to Fund performance. Our largest energy holdings were MURPHY OIL and VALERO ENERGY. Murphy Oil continued to benefit from its contract to supply Wal-Mart's (not a Fund holding) gas stations. Also, new discoveries in the Congo have the potential to boost the company's production capacity. Valero is a leading refiner of grades of oil that are heavier and higher in sulfur. While these grades cost somewhat more to refine, they cost much less to buy, giving Valero a cost advantage over its competitors. Within the financials sector, life insurer PRUDENTIAL contributed to Fund performance while FANNIE MAE detracted. Prudential's commitment to returning excess capital to shareholders has been a major driver of its performance for the last several years. Fannie Mae, a government-sponsored mortgage company, continued to be hurt by accounting and regulatory probes; nonetheless we continued to hold it because we believe it represents a compelling long-term investment. - -------------------------------------------------------------------------------- RETURNS AND PERFORMANCE SUMMARIES, BY SELECTED SECTORS, FUND VS. S&P 500 INDEX, 8/31/04 - 8/31/05 SECTOR RETURN, SECTOR RETURN, PERFORMANCE SECTOR FUND INDEX SUMMARY CONSUMER DISCRETIONARY 17.55% 11.33% For much of the fiscal year, the market worried that (The Fund's leisure rising short-term interest rates and energy prices might holdings are largely from crimp consumer spending--but those fears proved to be the consumer discretionary largely unfounded. A strengthening economy kept sector.) consumers spending and traveling, and generous incentives boosted new vehicle sales. ENERGY 67.69 51.85 As oil prices rose, so did earnings by many companies in the energy sector. Integrated oil and gas, equipment and services, and refining and marketing stocks all were strong. While oil grabbed the headlines, the price of natural gas, coal and other fuels also rose, benefiting a host of companies within the sector. FINANCIALS 10.43 4.29 While short-term interest rates rose, long-term rates remained historically low, aiding real estate and mortgage-related stocks. As a group, banks, credit card issuers and other diversified financial companies lagged the market as their cost of funds rose in concert with Fed tightening. Improvements in stock market performance helped brokerage, asset management and investment firms. HEALTH CARE 29.46 9.15 Many investors favored health care stocks--both because they are less sensitive to the economy and because many of them pay relatively attractive dividends. While somewhat defensive, the sector is poised to benefit from an aging population. Biotech stocks lagged early in the fiscal year but recovered, while health care services stocks were among the sector's strongest performers. INFORMATION TECHNOLOGY 29.82 16.43 Particularly in late 2004, and mid-2005, information technology stocks exhibited strength. Declining semiconductor inventories and stronger-than-expected demand for cell phones and computers (particularly laptops) were important factors in this strength. Also, investors viewed many information technology stocks as reasonably valued. Source: Lipper, Inc. - -------------------------------------------------------------------------------- 4 AIM MULTI-SECTOR FUND Within the health care sector, PACIFICARE contributed to Fund performance while FOREST LABS detracted. PacifiCare has long been regarded as a well-managed industry leader, but its stock got an added boost when the company announced in July that it would merge with UnitedHealth Group (not a Fund holding). Forest Labs has faced increased generic competition and its product pipeline appears to us to have faltered. As a result, we reduced our exposure to the company. Of the five sectors in which the Fund primarily invests, performance varied widely... Within the information technology sector, APPLE COMPUTER helped while AVID TECHNOLOGY hindered Fund performance. Apple's stock has performed well for several years, due in large part to the phenomenal success of the company's iPod - --REGISTERED TRADEMARK-- device and iTunes music store. Avid Technology's preeminent position in digital editing platforms and professional digital newsrooms could not overcome poor execution and a questionable acquisition strategy. We eliminated Avid Technology from the Fund. Within the leisure sector, HARRAH'S ENTERTAINMENT helped while newspaper publisher TRIBUNE hindered Fund performance. Harrah's seems not to have been hurt by rising gasoline prices, as many investors had feared, and the company continued to report good earnings. Tribune was hurt as some if its employment and real estate advertising moved to the Internet, and the company found itself under scrutiny regarding its circulation figures. As a result, we eliminated Tribune from the portfolio. IN CLOSING At the close of the fiscal year, economic data painted a generally positive picture of the U.S. economy, despite rising short-term interest rates and historically high energy prices. No one was certain how significant the effects of Hurricane Katrina would be for the nation's economy or for individual sectors or companies. That is why we continue to maintain a long-term investment horizon, and why we encourage shareholders to do the same. As always, we thank you for your continued investment in AIM Multi-Sector Fund.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2005, through August 31, 2005. ACTUAL EXPENSES The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the table under the heading entitled "Actual Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The Fund's actual cumulative total returns at net asset value after expenses for the six months ended August 31, 2005, appear in the table "Fund vs. Indexes" on Page 3. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions, and redemption fees, if any. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- ACTUAL HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES) BEGINNING ACCOUNT ENDING ACCOUNT EXPENSES ENDING ACCOUNT EXPENSES SHARE VALUE VALUE PAID DURING VALUE PAID DURING CLASS (3/1/05) (8/31/05)/1/ PERIOD/2/,/3/ (8/31/05) PERIOD/2/,/4/ A $ 1,000.00 $ 1,085.40 $ 7.73 $ 1,017.80 $ 7.48 B 1,000.00 1,081.40 11.33 1,014.32 10.97 C 1,000.00 1,081.50 11.33 1,014.32 10.97 /1/The actual ending account value is based on the actual total return of the Fund for the period March 1, 2005, through August 31, 2005, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund's expense ratio and a hypothetical annual return of 5% before expenses.

("AIM"). Based upon the recommendation of the Investments Committee of the Board, which is comprised solely of independent trustees, at a meeting held on June 30,2005, the Board, including all of the independent trustees, approved the continuance of the advisory agreement (the "Advisory Agreement") between the Fund and AIM for another year, effective July 1,2005. The Board considered the factors discussed below in evaluating the fairness and reasonableness of the Advisory Agreement at the meeting on June 30, 2005 and as part of the Board's ongoing oversight of the Fund. In their deliberations, the Board and the independent trustees did not identify any particular factor that was controlling, and each trustee attributed different weights to the various factors. One of the responsibilities of the Senior Officer of the Fund, who is independent of AIM and AIM's affiliates, is to manage the process by which the Fund's proposed management fees are negotiated to ensure that they are negotiated in a manner which is at arm's length and reasonable. To that end, the Senior Officer must either supervise a competitive bidding process or prepare an independent written evaluation. The Senior Officer has recommended an independent written evaluation in lieu of a competitive bidding process and, upon the direction of the Board, has prepared such an independent written evaluation. Such written evaluation also considered certain of the factors discussed below. In addition, as discussed below, the Senior Officer made certain recommendations to the Board in connection with such written evaluation. The discussion below serves as a summary of the Senior Officer's independent written evaluation and recommendations to the Board in connection therewith, as well as a discussion of the material factors and the conclusions with respect thereto that formed the basis for the Board's approval of the Advisory Agreement. After consideration of all of the factors below and based on its informed business judgment, the Board determined that the Advisory Agreement is in the best interests of the Fund and its shareholders and that the compensation to AIM under the Advisory Agreement is fair and reasonable and would have been obtained through arm's length negotiations. .. The nature and extent of the advisory services to be provided by AIM. The Board reviewed the services to be provided by AIM under the Advisory Agreement. Based on such review, the Board concluded that the range of services to be provided by AIM under the Advisory Agreement was appropriate and that AIM currently is providing services in accordance with the terms of the Advisory Agreement. .. The quality of services to be provided by AIM. The Board reviewed the credentials and experience of the officers and employees of AIM who will provide investment advisory services to the Fund. In reviewing the qualifications of AIM to provide investment advisory services, the Board reviewed the qualifications of AIM's investment personnel and considered such issues as AIM's portfolio and product review process, various back office support functions provided by AIM and AIM's equity and fixed income trading operations. Based on the review of these and other factors, the Board concluded that the quality of services to be provided by AIM was appropriate and that AIM currently is providing satisfactory services in accordance with the terms of the Advisory Agreement. .. The performance of the Fund relative to comparable funds. The Board reviewed the performance of the Fund during the past one and two calendar years against the performance of funds advised by other advisors with investment strategies comparable to those of the Fund. The Board noted that the Fund's performance in such periods was above the median performance of such comparable funds. The Board also noted that AIM began serving as investment advisor to the Fund in November 2003. Based on this review, the Board concluded that no changes should be made to the Fund and that it was not necessary to change the Fund's portfolio management team at this time. .. The performance of the Fund relative to indices. The Board reviewed the performance of the Fund during the past one and two calendar years against the performance of the Lipper Multi-Cap Core Index. The Board noted that the Fund's performance for the two year period was comparable to the performance of such Index and was above the Index performance for the one year period. The Board also noted that AIM began serving as investment advisor to the Fund in November 2003. Based on this review, the Board concluded that no changes should be made to the Fund and that it was not necessary to change the Fund's portfolio management team at this time. .. Meeting with the Fund's portfolio managers and investment personnel. With respect to the Fund, the Board is meeting periodically with such Fund's portfolio managers and/or other investment personnel and believes that such individuals are competent and able to continue to carry out their responsibilities under the Advisory Agreement. .. Overall performance of AIM. The Board considered the overall performance of AIM in providing investment advisory and portfolio administrative services to the Fund and concluded that such performance was satisfactory. .. Fees relative to those of clients of AIM with comparable investment strategies. The Board noted that AIM does not serve as an advisor to other mutual funds or other clients with investment strategies comparable to those of the Fund. .. Fees relative to those of comparable funds with other advisors. The Board reviewed the advisory fee rate for the Fund under the Advisory Agreement. The Board compared effective contractual advisory fee rates at a common asset level and noted that the Fund's rate was below the median rate of the funds advised by other advisors with investment strategies comparable to those of the Fund that the Board reviewed. The Board noted that AIM has agreed to waive advisory fees of the Fund and to limit the Fund's total operating expenses, as discussed below. Based on this review, the Board concluded that the advisory fee rate for the Fund under the Advisory Agreement was fair and reasonable. .. Expense limitations and fee waivers. The Board noted that AIM has contractually agreed to waive advisory fees of the Fund through December 31, 2009 to the extent necessary so that the advisory fees payable by the Fund do not exceed a specified maximum advisory fee rate, which maximum rate includes breakpoints and is based on net asset levels. The Board considered the contractual nature of this fee waiver and noted that it remains in effect until December 31, 2009. The Board noted that AIM has contractually agreed to waive fees and/or limit expenses of the Fund through August 31, 2005 in an amount necessary to limit total annual operating expenses to a specified percentage of average daily net assets for each class of the Fund. The Board considered the contractual nature of this fee waiver/expense limitation and noted that it remains in effect until August 31, 2005. The Board considered the effect these fee waivers/expense limitations would have on the Fund's estimated expenses and concluded that the levels of fee waivers/expense limitations for the Fund were fair and reasonable. .. Breakpoints and economies of scale. The Board reviewed the structure of the Fund's advisory fee under the Advisory Agreement, noting that it does not include any breakpoints. The Board considered whether it would be appropriate to add advisory fee breakpoints for the Fund or whether, due to the nature of the Fund and the advisory fee structures of comparable funds, it was reasonable to structure the advisory fee without breakpoints. Based on this review, the Board concluded that it was not necessary to add advisory fee breakpoints to the Fund's advisory fee schedule. The Board reviewed the level of the Fund's advisory fees, and noted that such fees, as a percentage of the Fund's net assets, would remain constant under the Advisory Agreement because the Advisory Agreement does not include any breakpoints. The Board noted that AIM has contractually agreed to waive advisory fees of the Fund through December 31, 2009 to the extent necessary so that the advisory fees payable by the Fund do not exceed a specified maximum advisory fee rate, which maximum rate includes breakpoints and is based on net asset levels. The Board concluded that the Fund's fee levels under the Advisory Agreement therefore would not reflect economies of scale, although the advisory fee waiver reflects economies of scale. (Continued on Page 10) 9 AIM MULTI-SECTOR FUND .. Investments in affiliated money market funds. The Board also took into account the fact that uninvested cash and cash collateral from securities lending arrangements (collectively, "cash balances") of the Fund may be invested in money market funds advised by AIM pursuant to the terms of an SEC exemptive order. The Board found that the Fund may realize certain benefits upon investing cash balances in AIM advised money market funds, including a higher net return, increased liquidity, increased diversification or decreased transaction costs. The Board also found that the Fund will not receive reduced services if it invests its cash balances in such money market funds. The Board noted that, to the extent the Fund invests in affiliated money market funds, AIM has voluntarily agreed to waive a portion of the advisory fees it receives from the Fund attributable to such investment. The Board further determined that the proposed securities lending program and related procedures with respect to the lending Fund is in the best interests of the lending Fund and its respective shareholders. The Board therefore concluded that the investment of cash collateral received in connection with the securities lending program in the money market funds according to the procedures is in the best interests of the lending Fund and its respective shareholders. .. Independent written evaluation and recommendations of the Fund's Senior Officer. The Board noted that, upon their direction, the Senior Officer of the Fund, who is independent of AIM and AIM's affiliates, had prepared an independent written evaluation in order to assist the Board in determining the reasonableness of the proposed management fees of the AIM Funds, including the Fund. The Board noted that the Senior Officer's written evaluation had been relied upon by the Board in this regard in lieu of a competitive bidding process. In determining whether to continue the Advisory Agreement for the Fund, the Board considered the Senior Officer's written evaluation and the recommendation made by the Senior Officer to the Board that the Board consider implementing a process to assist them in more closely monitoring the performance of the AIM Funds. The Board concluded that it would be advisable to implement such a process as soon as reasonably practicable. .. Profitability of AIM and its affiliates. The Board reviewed information concerning the profitability of AIM's (and its affiliates') investment advisory and other activities and its financial condition. The Board considered the overall profitability of AIM, as well as the profitability of AIM in connection with managing the Fund. The Board noted that AIM's operations remain profitable, although increased expenses in recent years have reduced AIM's profitability. Based on the review of the profitability of AIM's and its affiliates' investment advisory and other activities and its financial condition, the Board concluded that the compensation to be paid by the Fund to AIM under its Advisory Agreement was not excessive. .. Benefits of soft dollars to AIM. The Board considered the benefits realized by AIM as a result of brokerage transactions executed through "soft dollar" arrangements. Under these arrangements, brokerage commissions paid by the Fund and/or other funds advised by AIM are used to pay for research and execution services. This research is used by AIM in making investment decisions for the Fund. The Board concluded that such arrangements were appropriate. .. AIM's financial soundness in light of the Fund's needs. The Board considered whether AIM is financially sound and has the resources necessary to perform its obligations under the Advisory Agreement, and concluded that AIM has the financial resources necessary to fulfill its obligations under the Advisory Agreement. .. Historical relationship between the Fund and AIM. In determining whether to continue the Advisory Agreement for the Fund, the Board also considered the prior relationship between AIM and the Fund, as well as the Board's knowledge of AIM's operations, and concluded that it was beneficial to maintain the current relationship, in part, because of such knowledge. The Board also reviewed the general nature of the non-investment advisory services currently performed by AIM and its affiliates, such as administrative, transfer agency and distribution services, and the fees received by AlM and its affiliates for performing such services. In addition to reviewing such services, the trustees also considered the organizational structure employed by AIM and its affiliates to provide those services. Based on the review of these and other factors, the Board concluded that AIM and its affiliates were qualified to continue to provide non-investment advisory services to the Fund, including administrative, transfer agency and distribution services, and that AIM and its affiliates currently are providing satisfactory non-investment advisory services. .. Other factors and current trends. In determining whether to continue the Advisory Agreement for the Fund, the Board considered the fact that AIM, along with others in the mutual fund industry, is subject to regulatory inquiries and litigation related to a wide range of issues. The Board also considered the governance and compliance reforms being undertaken by AIM and its affiliates, including maintaining an internal controls committee and retaining an independent compliance consultant, and the fact that AIM has undertaken to cause the Fund to operate in accordance with certain governance policies and practices. The Board concluded that these actions indicated a good faith effort on the part of AIM to adhere to the highest ethical standards, and determined that the current regulatory and litigation environment to which AIM is subject should not prevent the Board from continuing the Advisory Agreement for the Fund. 10 SUPPLEMENT TO ANNUAL REPORT DATED 8/31/05 AIM MULTI-SECTOR FUND INSTITUTIONAL CLASS SHARES The following information has been prepared to provide Institutional Class shareholders with a performance overview specific to their holdings.

AIMINVESTMENTS.COM l-MSE-INS-l OUR SOLUTIONS.] [AIM INVESTMENTS LOGO] - REGISTERED TRADEMARK - - REGISTERED TRADEMARK - INFORMATION ABOUT YOUR FUND'S EXPENSES CALCULATING YOUR ONGOING FUND EXPENSES EXAMPLE As a shareholder of the Fund, you incur ongoing costs, including management fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2005, through August 31, 2005. ACTUAL EXPENSES The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the table under the heading entitled "Actual Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The Fund's actual cumulative total return after expenses for the six months ended August 31, 2005, appears in the table on the front of this supplement. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. - -------------------------------------------------------------------------------- ACTUAL HYPOTHETICAL (5% ANNUAL RETURN BEFORE EXPENSES) BEGINNING ACCOUNT ENDING ACCOUNT EXPENSES ENDING ACCOUNT EXPENSES SHARE VALUE VALUE PAID DURING VALUE PAID DURING CLASS (3/1/05) (8/31/05)/1/ PERIOD/2/ (8/31/05) PERIOD/2/ Institutional $ 1,000.00 $ 1,088.10 $ 5.11 $ 1,020.32 $ 4.94 /1/The actual ending account value is based on the actual total return of the Fund for the period March 1, 2005, through August 31, 2005, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund's expense ratio and a hypothetical annual return of 5% before expenses The Fund's actual cumulative total return after expenses for the six months ended August 31, 2005, appears in the table on the front of this supplement. /2/ Expenses are equal to the Fund's annualized expense ratio, 0.97% for the Institutional Class shares, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). - -------------------------------------------------------------------------------- FINANCIALS SCHEDULE OF INVESTMENTS August 31, 2005 MARKET SHARES VALUE ------------------------------------------------------------ DOMESTIC COMMON STOCKS-80.39% ADVERTISING-1.78% Omnicom Group Inc. 44,320 $ 3,565,101 ------------------------------------------------------------ APPAREL, ACCESSORIES & LUXURY GOODS-0.79% Polo Ralph Lauren Corp. 32,090 1,590,059 ------------------------------------------------------------ APPLICATION SOFTWARE-0.81% Amdocs Ltd./(a)/ 55,600 1,631,860 ------------------------------------------------------------ ASSET MANAGEMENT & CUSTODY BANKS-2.10% Bank of New York Co., Inc.

F-6 NOTES TO FINANCIAL STATEMENTS August 31, 2005 NOTE 1--SIGNIFICANT ACCOUNTING POLICIES AIM Multi-Sector Fund, formerly INVESCO Multi-Sector Fund, (the "Fund") is a series portfolio of AIM Counselor Series Trust (the "Trust"). The Trust is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end series management investment company consisting of two separate portfolios, each authorized to issue an unlimited number of shares of beneficial interest. The Fund currently offers multiple classes of shares. Matters affecting each portfolio or class will be voted on exclusively by the shareholders of such portfolio or class. The assets, liabilities and operations of each portfolio are accounted for separately. Information presented in these financial statements pertains only to the Fund. The Fund's investment objective is to seek capital growth. Under the Trust's organizational documents, each Trustee, officer, employee or other agent of the Trust (including the Trust's investment manager) is indemnified against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts that contain a variety of indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund has not had prior claims or losses pursuant to these contracts. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates. The following is a summary of the significant accounting policies followed by the Fund in the preparation of its financial statements. A. SECURITY VALUATIONS -- Securities, including restricted securities, are valued according to the following policy. A security listed or traded on an exchange (except convertible bonds) is valued at its last sales price as of the close of the customary trading session on the exchange where the security is principally traded, or lacking any sales on a particular day, the security is valued at the closing bid price on that day. Each security traded in the over-the-counter market (but not securities reported on the NASDAQ National Market System) is valued on the basis of prices furnished by independent pricing services, which may be considered fair valued, or market makers. Each security reported on the NASDAQ National Market System is valued at the NASDAQ Official Closing Price ("NOCP") as of the close of the customary trading session on the valuation date or absent a NOCP, at the closing bid price. Futures contracts are valued at the final settlement price set by an exchange on which they are principally traded. Listed options are valued at the mean between the last bid and the ask prices from the exchange on which they are principally traded. Options not listed on an exchange are valued by an independent source at the mean between the last bid and ask prices. For purposes of determining net asset value per share, futures and option contracts generally will be valued 15 minutes after the close of the customary trading session of the New York Stock Exchange ("NYSE"). Investments in open-end registered investment companies and closed-end registered investment companies that do not trade on an exchange are valued at the end of day net asset value per share. Investments in closed-end registered investment companies that trade on an exchange are valued at the last sales price as of the close of the customary trading session on the exchange where the security is principally traded. Debt obligations (including convertible bonds) are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to specific securities, dividend rate, yield, quality, type of issue, coupon rate, maturity, individual trading characteristics and other market data. Short-term obligations having 60 days or less to maturity and commercial paper are valued at amortized cost which approximates market value. Securities for which market prices are not provided by any of the above methods are valued based upon quotes furnished by independent sources and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and asked prices. Foreign securities (including foreign exchange contracts) are converted into U.S. dollar amounts using the applicable exchange rates as of the close of the NYSE. Generally, trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of the close of the respective markets. Events affecting the values of such foreign securities may occur between the times at which the particular foreign market closes and the close of the customary trading session of the NYSE which would not ordinarily be reflected in the computation of the Fund's net asset value. If the event is likely to have affected the closing price of the security, the security will be valued at fair value in good faith using procedures approved by the Board of Trustees. Adjustments to closing prices to reflect fair value may also be based on a screening process of an independent pricing service to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. Foreign securities meeting the approved degree of certainty that the price is not reflective of current market value will be priced at the indication of fair value from the independent pricing service. Multiple factors may be considered by the independent pricing service in determining adjustments to reflect fair value and may include information relating to sector indices, ADRs and domestic and foreign index futures. Securities for which market quotations are not readily available or are unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust's officers following procedures approved by the Board of Trustees. Issuer specific events, market trends, bid/ask quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security's fair value. B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME -- Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income is recorded on the accrual basis from settlement date. Dividend income is recorded on the ex-dividend date. F-7 Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of realized and unrealized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the realized and unrealized net gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund's net asset value and, accordingly, they reduce the Fund's total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and Statement of Changes in Net Assets, or the net investment income per share and ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the advisor. The Fund allocates income and realized and unrealized capital gains and losses to a class based on the relative net assets of each class. C. COUNTRY DETERMINATION -- For the purposes of making investment selection decisions and presentation in the Schedule of Investments, AIM may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer's securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be United States of America unless otherwise noted. D. DISTRIBUTIONS -- Distributions from income and net realized capital gain, if any, are generally paid annually and recorded on ex-dividend date. The Fund may elect to use a portion of the proceeds from redemptions as distributions for federal income tax purposes. E. FEDERAL INCOME TAXES -- The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code necessary to qualify as a regulated investment company and, as such, will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) which is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements. F. EXPENSES -- Fees provided for under the Rule 12b-1 plan of a particular class of the Fund are charged to the operations of such class. Transfer agency fees and expenses and other shareholder recordkeeping fees and expenses attributable to the Institutional Class are charged to such class. Transfer agency fees and expenses and other shareholder recordkeeping fees and expenses relating to all other classes are allocated among those classes based on relative net assets. All other expenses are allocated among the classes based on relative net assets. G. FOREIGN CURRENCY TRANSLATIONS -- Foreign currency is valued at the close of the NYSE based on quotations posted by banks and major currency dealers. Portfolio securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts at date of valuation. Purchases and sales of portfolio securities (net of foreign taxes withheld on disposition) and income items denominated in foreign currencies are translated into U.S. dollar amounts on the respective dates of such transactions. The Fund does not separately account for the portion of the results of operations resulting from changes in foreign exchange rates on investments and the fluctuations arising from changes in market prices of securities held. The combined results of changes in foreign exchange rates and the fluctuation of market prices on investments (net of estimated foreign tax withholding) are included with the net realized and unrealized gain or loss from investments in the Statement of Operations. Reported net realized foreign currency gains or losses arise from (i) sales of foreign currencies, (ii) currency gains or losses realized between the trade and settlement dates on securities transactions, and (iii) the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign currency gains and losses arise from changes in the fair values of assets and liabilities, other than investments in securities at fiscal period end, resulting from changes in exchange rates. H. FOREIGN CURRENCY CONTRACTS -- A foreign currency contract is an obligation to purchase or sell a specific currency for an agreed-upon price at a future date. The Fund may enter into a foreign currency contract to attempt to minimize the risk to the Fund from adverse changes in the relationship between currencies. The Fund may also enter into a foreign currency contract for the purchase or sale of a security denominated in a foreign currency in order to "lock in" the U.S. dollar price of that security. The Fund could be exposed to risk if counterparties to the contracts are unable to meet the terms of their contracts or if the value of the foreign currency changes unfavorably. I. COVERED CALL OPTIONS -- The Fund may write call options, on a covered basis; that is, the Fund will own the underlying security. When the Fund writes a covered call option, an amount equal to the premium received by the Fund is recorded as an asset and an equivalent liability. The amount of the liability is subsequently "marked-to-market" to reflect the current market value of the option written. The current market value of a written option is the mean between the last bid and asked prices on that day. If a written call option expires on the stipulated expiration date, or if the Fund enters into a closing purchase transaction, the Fund realizes a gain (or a loss if the closing purchase transaction exceeds the premium received when the option was written) without regard to any unrealized gain or loss on the underlying security, and the liability related to such option is extinguished. If a written option is exercised, the Fund realizes a gain or a loss from the sale of the underlying security and the proceeds of the sale are increased by the premium originally received. A risk in writing a call option is that the Fund gives up the opportunity for profit if the market price of the security increases and the option is exercised. J. PUT OPTIONS -- The Fund may purchase put options. By purchasing a put option, the Fund obtains the right (but not the obligation) to sell the option's underlying instrument at a fixed strike price. In return for this right, the Fund pays an option premium. The option's underlying instrument may be a security or a futures contract. Put options may be used by the Fund to hedge securities it owns by locking in a minimum price at which the Fund can sell. If security prices fall, the put option could be exercised to offset all or a portion of the Fund's resulting losses. At the same time, because the maximum the Fund has at risk is the cost of the option, purchasing put options does not eliminate the potential for the Fund to profit from an increase in the value of the securities hedged. A risk in buying an option is that the Fund pays a premium whether or not the option is exercised. In addition, there can be no assurance that a liquid secondary market will exist for any option purchased or sold. K. COLLATERAL -- To the extent the Fund has pledged or segregated a security as collateral and that security is subsequently sold, it is the Fund's practice to replace such collateral no later than the next business day. F-8 NOTE 2--ADVISORY FEES AND OTHER FEES PAID TO AFFILIATES The Trust has entered into a master investment advisory agreement with A I M Advisors, Inc. ("AIM"). Under the terms of the investment advisory agreement, the Fund pays an advisory fee at the annual rate of 0.75% of the Fund's average daily net assets. Through December 31, 2009, AIM has contractually agreed to waive advisory fees to the extent necessary so that the advisory fees payable by the Fund (based on the Fund's average daily net assets) do not exceed the annual rate of: AVERAGE NET ASSETS RATE ---------------------------------------------------- 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% ---------------------------------------------------- Prior to September 30, 2004, under the terms of a master sub-advisory agreement between AIM and INVESCO Institutional (N.A.), Inc. ("INVESCO"), AIM paid INVESCO 40% of the fee paid by the Fund to AIM. This sub-advisory agreement expired on September 30, 2004. AIM has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit total annual operating expenses (excluding certain items discussed below) of Class A, Class B, Class C and Institutional Class shares to 1.90%, 2.65%, 2.65% and 1.65% of average daily net assets, respectively, through August 31, 2006. In determining the advisor's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the total annual fund operating expenses to exceed the limits stated above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary items (these are expenses that are not anticipated to arise from the Fund's day-to-day operations), or items designated as such by the Fund's Board of Trustees; (v) expenses related to a merger or reorganization, as approved by the Fund's Board of Trustees; and (vi) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Currently, in addition to the expense reimbursement arrangement with AMVESCAP PLC ("AMVESCAP") described more fully below, the expense offset arrangements from which the Fund may benefit are in the form of credits that the Fund receives from banks where the Fund or its transfer agent has deposit accounts in which it holds uninvested cash. Those credits are used to pay certain expenses incurred by the Fund. Further, AIM has voluntarily agreed to waive advisory fees of the Fund in the amount of 25% of the advisory fee AIM receives from the affiliated money market funds on investments by the Fund in such affiliated money market funds. AIM is also voluntarily waiving a portion of the advisory fee payable by the Fund equal to the difference between the income earned from investing in the affiliated money market fund and the hypothetical income earned from investing in an appropriate comparative benchmark. Voluntary fee waivers or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors. For the year ended August 31, 2005, AIM waived fees of $51,656. At the request of the Trustees of the Trust, AMVESCAP agreed to reimburse expenses incurred by the Fund in connection with market timing matters in the AIM Funds, which may include legal, audit, shareholder reporting, communications and trustee expenses. These expenses along with the related expense reimbursement, are included in the Statement of Operations. For the year ended August 31, 2005, AMVESCAP reimbursed expenses of the Fund in the amount of $19,948. The Fund, pursuant to a master administrative services agreement with AIM, has agreed to pay AIM for certain administrative costs incurred in providing accounting services to the Fund. Pursuant to such agreement, for the year ended August 31, 2005, AIM was paid $50,000. The Fund, pursuant to a transfer agency and service agreement, has agreed to pay AIM Investment Services, Inc. ("AISI") a fee for providing transfer agency and shareholder services to the Fund and reimburse AISI for certain expenses incurred by AISI in the course of providing such services. AISI may make payments to intermediaries that provide omnibus account services, sub-accounting services and/or networking services. For the year ended August 31, 2005, the Fund paid AISI $175,104 for Class A, Class B and Class C share classes and $3,379 for Institutional Class shares. The Trust has entered into master distribution agreements with A I M Distributors, Inc. ("ADI") to serve as the distributor for the Class A, Class B, Class C and Institutional Class shares of the Fund. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund's Class A, Class B and Class C shares (collectively the "Plans"). The Fund, pursuant to the Class A, Class B and Class C Plans, pays ADI compensation at the annual rate of 0.25% of the Fund's average daily net assets of Class A shares and 1.00% of the average daily net assets of Class B and Class C shares. Prior to July 1, 2005, the Fund paid ADI 0.35% of the average daily net assets of Class A shares. Of these amounts, up to 0.25% of the average daily net assets of the Class A, Class B or Class C shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such classes. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. National Association of Securities Dealers ("NASD") Rules impose a cap on the total sales charges, including asset-based sales charges that may be paid by any class of shares of the Fund. Pursuant to the Plans, for the year ended August 31, 2005, the Class A, Class B and Class C shares paid $176,390, $156,282 and $213,976, respectively. Front-end sales commissions and contingent deferred sales charges ("CDSC") (collectively the "sales charges") are not recorded as expenses of the Fund. Front-end sales commissions are deducted from proceeds from the sales of Fund shares prior to investment in Class A shares of the Fund. CDSC are deducted from redemption proceeds prior to remittance to the shareholder. For the year ended August 31, 2005, ADI advised the Fund that it retained $52,345 in front-end sales commissions from the sale of Class A shares and $221, $13,836 and $2,983 from Class A, Class B and Class C shares, respectively, for CDSC imposed upon redemptions by shareholders. Certain officers and trustees of the Trust are officers and directors of AIM, AISI, INVESCO and/or ADI. F-9 NOTE 3--INVESTMENTS IN AFFILIATES The Fund is permitted, pursuant to an exemptive order from the Securities and Exchange Commission ("SEC") and approved procedures by the Board of Trustees, to invest daily available cash balances in affiliated money market funds. The Fund and the money market fund below have the same investment advisor and therefore, are considered to be affiliated. The table below shows the transactions in and earnings from investments in an affiliated money market fund for the year ended August 31, 2005. CHANGE IN MARKET PROCEEDS UNREALIZED MARKET REALIZED VALUE PURCHASES FROM APPRECIATION VALUE DIVIDEND GAIN FUND 08/31/04 AT COST SALES (DEPRECIATION) 08/31/05 INCOME (LOSS) - ------------------------------------------------------------------------------------------------------------------------- Premier Portfolio-Institutional Class $2,605,685 $113,885,415 $(104,739,319) $-- $11,751,781 $149,465 $-- - ------------------------------------------------------------------------------------------------------------------------- NOTE 4--SECURITY TRANSACTIONS WITH AFFILIATED FUNDS The Fund is permitted to purchase or sell securities from or to certain other AIM Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment advisor (or affiliated investment advisors), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. Pursuant to these procedures, during the year ended August 31, 2005, the Fund engaged in securities purchases of $1,277,480 and sales of $505,622, which resulted in net realized gains of $66,634. NOTE 5--EXPENSE OFFSET ARRANGEMENT The expense offset arrangement is comprised of transfer agency credits which result from balances in Demand Deposit Accounts (DDA) used by the transfer agent for clearing shareholder transactions. For the year ended August 31, 2005, the Fund received credits from this arrangement, which resulted in the reduction of the Fund's total expenses of $3,029. NOTE 6--TRUSTEES' AND OFFICER'S FEES AND BENEFITS "Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund to pay remuneration to each Trustee and Officer of the Fund who is not an "interested person" of AIM. Trustees have the option to defer compensation payable by the Fund, and "Trustees' and Officer's Fees and Benefits" also include amounts accrued by the Fund to fund such deferred compensation amounts. Those Trustees who defer compensation have the option to select various AIM Funds in which their deferral accounts shall be deemed to be invested. Finally, current Trustees are eligible to participate in a retirement plan that provides for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees who also participate in a retirement plan and receive benefits under such plan. "Trustees' and Officer's Fees and Benefits" include amounts accrued by the Fund to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Fund. During the year ended August 31, 2005, the Fund paid legal fees of $4,253 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the Independent Trustees. A member of that firm is a Trustee of the Trust. NOTE 7--BORROWINGS Pursuant to an exemptive order from the SEC, the Fund may participate in an interfund lending facility that AIM has established for temporary borrowings by the AIM Funds. An interfund loan will be made under this facility only if the loan rate (an average of the rate available on bank loans and the rate available on investments in overnight repurchase agreements) is favorable to both the lending fund and the borrowing fund. A loan will be secured by collateral if the Fund's aggregate borrowings from all sources exceeds 10% of the Fund's total assets. To the extent that the loan is required to be secured by collateral, the collateral is marked to market daily to ensure that the market value is at least 102% of the outstanding principal value of the loan. The Fund is a participant in an uncommitted unsecured revolving credit facility with State Street Bank and Trust Company ("SSB"). The Fund may borrow up to the lesser of (i) $125,000,000, or (ii) the limits set by its prospectus for borrowings. The Fund and other funds advised by AIM which are parties to the credit facility can borrow on a first come, first served basis. Principal on each loan outstanding shall bear interest at the bid rate quoted by SSB at the time of the request for the loan. During the year ended August 31, 2005, the Fund did not borrow or lend under the interfund lending facility or borrow under the uncommitted unsecured revolving credit facility. Additionally, the Fund is permitted to temporarily carry a negative or overdrawn balance in its account with SSB, the custodian bank. To compensate the custodian bank for such overdrafts, the overdrawn Fund may either (i) leave funds as a compensating balance in the account so the custodian can be compensated by earning the additional interest; or (ii) compensate by paying the custodian bank at a rate agreed upon by the custodian bank and AIM, not to exceed the rate contractually agreed upon.

The Fund's unrealized appreciation (depreciation) difference is attributable primarily to the deferral of losses on wash sales, the recognition for tax purposes of unrealized gains on passive foreign investment companies and the deferral of losses on certain straddle transactions. The tax-basis unrealized appreciation (depreciation) on investments amount includes appreciation on foreign currencies of $588. The temporary book/tax differences are a result of timing differences between book and tax recognition of income and/or expenses. The Fund's temporary book/tax differences are the result of the trustee deferral of compensation and retirement plan expenses. The Fund had no capital loss carryforward as of August 31, 2005. NOTE 10--INVESTMENT SECURITIES The aggregate amount of investment securities (other than short-term securities and money market funds) purchased and sold by the Fund during the year ended August 31, 2005 was $161,873,163 and $70,830,269, respectively. UNREALIZED APPRECIATION (DEPRECIATION) OF INVESTMENT SECURITIES ON A TAX BASIS ------------------------------------------------------------------------------ Aggregate unrealized appreciation of investment securities $30,159,437 ------------------------------------------------------------------------------ Aggregate unrealized (depreciation) of investment securities (2,531,534) ------------------------------------------------------------------------------ Net unrealized appreciation of investment securities $27,627,903 ------------------------------------------------------------------------------ Cost of investments for tax purposes is $173,925,411. F-11 NOTE 11--RECLASSIFICATION OF PERMANENT DIFFERENCES Primarily as a result of differing book/tax treatment of foreign currency transactions, passive foreign investment company transactions, and net operating losses, on August 31, 2005, undistributed net investment income (loss) was increased by $9,826, undistributed net realized gain (loss) was decreased by $289,824 and shares of beneficial interest increased by $279,998. This reclassification had no effect on the net assets of the Fund. NOTE 12--SHARE INFORMATION The Fund currently offers four different classes of shares: Class A shares, Class B shares, Class C shares and Institutional Class shares. Class A shares are sold with a front-end sales charge. Class B shares and Class C shares are sold with CDSC. Institutional Class shares are sold at net asset value. Under certain circumstances, Class A shares are subject to CDSC. Generally, Class B shares will automatically convert to Class A shares eight years after the end of the calendar month of purchase.

F-14 NOTE 14--LEGAL PROCEEDINGS Terms used in the Legal Proceedings Note are defined terms solely for the purpose of this note. SETTLED ENFORCEMENT ACTIONS AND INVESTIGATIONS RELATED TO MARKET TIMING On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment advisor to certain AIM Funds), AIM and A I M Distributors, Inc. ("ADI") (the distributor of the retail AIM Funds) reached final settlements with certain regulators, including the Securities and Exchange Commission ("SEC"), the New York Attorney General and the Colorado Attorney General, to resolve civil enforcement actions and/or investigations related to market timing and related activity in the AIM Funds, including those formerly advised by IFG. As part of the settlements, a $325 million fair fund ($110 million of which is civil penalties) has been created to compensate shareholders harmed by market timing and related activity in funds formerly advised by IFG. Half of this amount has already been paid to the fair fund pursuant to the terms of the settlement with the remainder due December 31, 2005. Additionally, AIM and ADI created a $50 million fair fund ($30 million of which is civil penalties) to compensate shareholders harmed by market timing and related activity in funds advised by AIM, which was done pursuant to the terms of the settlement. These two fair funds may increase as a result of contributions from third parties who reach final settlements with the SEC or other regulators to resolve allegations of market timing and/or late trading that also may have harmed applicable AIM Funds. These two fair funds will be distributed in accordance with a methodology to be determined by AIM's independent distribution consultant, in consultation with AIM and the independent trustees of the AIM Funds and acceptable to the staff of the SEC. As the methodology is unknown at the present time, management of AIM and the Fund are unable to estimate the impact, if any, that the distribution of these two fair funds may have on the Fund or whether such distribution will have an impact on the Fund's financial statements in the future. At the request of the trustees of the AIM Funds, AMVESCAP PLC ("AMVESCAP"), the parent company of IFG and AIM, has agreed to reimburse expenses incurred by the AIM Funds related to market timing matters. REGULATORY INQUIRIES AND PENDING LITIGATION IFG, AIM, ADI and/or related entities and individuals have received inquiries from numerous regulators in the form of subpoenas or other oral or written requests for information and/or documents related to one or more of the following issues, some of which concern one or more AIM Funds: market timing activity, late trading, fair value pricing, excessive or improper advisory and/or distribution fees, mutual fund sales practices, including revenue sharing and directed-brokerage arrangements, investments in securities of other registered investment companies, contractual plans, issues related to Section 529 college savings plans and procedures for locating lost securityholders. IFG, AIM and ADI are providing full cooperation with respect to these inquiries. As described more fully below, the AIM Funds, IFG, AIM, ADI and/or related entities and individuals are defendants in numerous civil lawsuits related to one or more of these issues. Regulatory actions and/or additional civil lawsuits related to these or other issues may be filed against the AIM Funds, IFG, AIM and/or related entities and individuals in the future. On April 12, 2005, the Attorney General of the State of West Virginia ("WVAG") filed a civil lawsuit against AIM, IFG and ADI, as well as numerous unrelated mutual fund complexes and financial institutions. None of the AIM Funds has been named as a defendant in this lawsuit. The WVAG complaint, filed in the Circuit Court of Marshall County, West Virginia [Civil Action No. 05-C-81], alleges, in substance, that AIM, IFG and ADI engaged in unfair competition and/or unfair or deceptive trade practices by failing to disclose in the prospectuses for the AIM Funds, including those formerly advised by IFG, that they had entered into certain arrangements permitting market timing of such Funds. As a result of the foregoing, the WVAG alleges violations of W. Va. Code (S) 46A-1-101, et seq. (the West Virginia Consumer Credit and Protection Act). The WVAG complaint is seeking, among other things, injunctive relief, civil monetary penalties and a writ of quo warranto against the defendants. If AIM is unsuccessful in its defense of the WVAG lawsuit, it could be barred from serving as an investment advisor for any investment company registered under the Investment Company Act of 1940, as amended (a "registered investment company"). Such results could affect the ability of AIM or any other investment advisor directly or indirectly owned by AMVESCAP, from serving as an investment advisor to any registered investment company, including the Fund. The Fund has been informed by AIM that, if these results occur, AIM will seek exemptive relief from the SEC to permit it to continue to serve as the Fund's investment advisor. There is no assurance that such exemptive relief will be granted. On July 7, 2005, the Supreme Court of West Virginia ruled in the context of a separate lawsuit that the WVAG does not have authority pursuant to W. Va. Code Section 46A-6-104 of the West Virginia Consumer Credit and Protection Act to bring an action based upon conduct that is ancillary to the purchase or sale of securities. AIM intends to seek dismissal of the WVAG's lawsuit against it, IFG and ADI in light of this ruling. On August 30, 2005, the West Virginia Office of the State Auditor--Securities Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of Right to Hearing to AIM and ADI. The WVASC makes findings of fact that essentially mirror the WVAG's allegations mentioned above and conclusions of law to the effect that AIM and ADI violated the West Virginia securities laws. The WVASC orders AIM and ADI to cease any further violations and seeks to impose monetary sanctions to be determined by the Commissioner. AIM and ADI have the right to contest the WVASC's findings and conclusions, which they intend to do. Civil lawsuits, including purported class action and shareholder derivative suits, have been filed against certain of the AIM Funds, IFG, AIM, ADI and/or related entities and individuals, depending on the lawsuit, alleging: . that the defendants permitted improper market timing and related activity in the AIM Funds; . that certain AIM Funds inadequately employed fair value pricing; . that the defendants charged excessive advisory and/or distribution fees and failed to pass on to shareholders the perceived savings generated by economies of scale and that the defendants adopted unlawful distribution plans; . that the defendants breached their fiduciary duties by charging distribution fees while AIM Funds and/or specific share classes were closed generally to new investors and/or while other share classes of the same AIM Fund were not charged the same distribution fees; . that the defendants improperly used the assets of the AIM Funds to pay brokers to aggressively promote the sale of the AIM Funds over other mutual funds and that the defendants concealed such payments from investors by disguising them as brokerage commissions; and . that the defendants breached their fiduciary duties by failing to ensure that the AIM Funds participated in class action settlements in which they were eligible to participate (this lawsuit was dismissed by the Court on August 12, 2005). F-15 NOTE 14--LEGAL PROCEEDINGS-CONTINUED These lawsuits allege as theories of recovery, depending on the lawsuit, violations of various provisions of the Federal and state securities laws and ERISA, negligence, breach of fiduciary duty and/or breach of contract. These lawsuits seek remedies that include, depending on the lawsuit, damages, restitution, injunctive relief, imposition of a constructive trust, removal of certain directors and/or employees, various corrective measures under ERISA, rescission of certain AIM Funds' advisory agreements and/or distribution plans and recovery of all fees paid, an accounting of all fund-related fees, commissions and soft dollar payments, restitution of all commissions and fees paid, and prospective relief in the form of reduced fees. All lawsuits based on allegations of market timing, late trading and related activity have been transferred to the United States District Court for the District of Maryland. On August 25, 2005, the Court issued rulings on the common issues of law presented in defendants' motions to dismiss the shareholder class and derivative complaints. These rulings were issued in the context of the Janus lawsuits, but the Court's legal determinations apply at the omnibus level to all cases within his track, including the AIM and IFG cases. The Court dismissed for failure to make pre-suit demand on the fund board all derivative causes of action but one: the excessive fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940 Act"), as to which the demand requirement does not apply. The Court dismissed all claims asserted in the class complaint but two: (i) the securities fraud claims under Section 10(b) of the Securities Exchange Act of 1934, and (ii) the excessive fee claim under Section 36(b) of the 1940 Act. In addition, the Court limited plaintiffs' potential recovery on the 36(b) claim to fees attributable to timing assets, as opposed to all fees on funds in which any timing occurred. The question whether the duplicative Section 36(b) claim properly belongs in the derivative complaint or in the class action complaint will be decided at a later date. The Court will subsequently issue an order applying his legal rulings to the allegations in the AIM and IFG complaints. At the present time, management of AIM and the Fund are unable to estimate the impact, if any, that the outcome of the Regulatory Inquiries and Pending Litigation described above may have on AIM, ADI or the Fund. * * * * * * * * * * * * * * * * As a result of the matters discussed above, investors in the AIM Funds might react by redeeming their investments. This might require the AIM Funds to sell investments to provide for sufficient liquidity and could also have an adverse effect on the investment performance of the AIM Funds. F-16 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Trustees and Shareholders of AIM Multi-Sector Fund: In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of AIM Multi-Sector Fund, formerly known as INVESCO Multi-Sector Fund, (one of the funds constituting AIM Counselor Series Trust, hereafter referred to as the "Fund") at August 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at August 31, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. /S/ PRICEWATERHOUSECOOPERS LLP October 19, 2005 Houston, Texas F-17 TRUSTEES AND OFFICERS As of August 31, 2005 The address of each trustee and officer of AIM Counselor Series Trust (the "Trust"), is 11 Greenway Plaza, Suite 100, Houston, Texas 77046.

The Audit Committee also has considered whether the provision of non-audit services that were rendered to AIM and AIM Affiliates that were not required to be pre-approved pursuant to SEC regulations, if any, is compatible with maintaining PWC's independence. PRE-APPROVAL OF AUDIT AND NON-AUDIT SERVICES POLICIES AND PROCEDURES As adopted by the Audit Committees of the AIM Funds (the "Funds") Last Amended September 13, 2005 I. Statement of Principles Under the Sarbanes-Oxley Act of 2002 and rules adopted by the Securities and Exchange Commission ("SEC") ("Rules"), the Audit Committees of the Funds' (the "Audit Committee") Board of Directors/Trustees (the "Board") are responsible for the appointment, compensation and oversight of the work of independent accountants (an "Auditor"). As part of this responsibility and to assure that the Auditor's independence is not impaired, the Audit Committees pre-approve the audit and non-audit services provided to the Funds by each Auditor, as well as all non-audit services provided by the Auditor to the Funds' investment adviser and to affiliates of the adviser that provide ongoing services to the Funds ("Service Affiliates") if the services directly impact the Funds' operations or financial reporting. The SEC Rules also specify the types of services that an Auditor may not provide to its audit client. The following policies and procedures comply with the requirements for pre-approval and provide a mechanism by which management of the Funds may request and secure pre-approval of audit and non- audit services in an orderly manner with minimal disruption to normal business operations. Proposed services either may be pre-approved without consideration of specific case-by-case services by the Audit Committees ("general pre-approval") or require the specific pre-approval of the Audit Committees ("specific pre - approval"). As set forth in these policies and procedures, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committees. Additionally, any fees exceeding 110% of estimated pre - -approved fee levels provided at the time the service was pre-approved will also require specific approval by the Audit Committees before payment is made. The Audit Committees will also consider the impact of additional fees on the Auditor's independence when determining whether to approve any additional fees for previously pre-approved services. The Audit Committees will annually review and generally pre-approve the services that may be provided by each Auditor without obtaining specific pre-approval from the Audit Committee. The term of any general pre-approval runs from the date of such pre-approval through September 30th of the following year, unless the Audit Committees consider a different period and state otherwise. The Audit Committees will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations. The purpose of these policies and procedures is to set forth the guidelines to assist the Audit Committees in fulfilling their responsibilities. II. Delegation The Audit Committees may from time to time delegate pre-approval authority to one or more of its members who are Independent Directors. All decisions to pre-approve a service by a delegated member shall be reported to the Audit Committee at its next quarterly meeting. III. Audit Services The annual audit services engagement terms will be subject to specific pre-approval of the Audit Committees. Audit services include the annual financial statement audit and other procedures such as tax provision work that is required to be performed by the independent auditor to be able to form an opinion on the Funds' financial statements. The Audit Committee will obtain, review and consider sufficient information concerning the proposed Auditor to make a reasonable evaluation of the Auditor's qualifications and independence. In addition to the annual Audit services engagement, the Audit Committees may grant general pre-approval for other audit services, which are those services that only the independent auditor reasonably can provide. Other Audit services may include services such as issuing consents for the inclusion of audited financial statements with SEC registration statements, periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. IV. Non-Audit Services The Audit Committees may provide general pre-approval of types of non-audit services described in this Section IV to the Funds and its Service Affiliates if the Audit Committees believe that the provision of the service will not impair the independence of the Auditor, is consistent with the SEC's Rules on auditor independence, and otherwise conforms to the Audit Committee's general principles and policies as set forth herein. The Audit Committees may provide specific pre-approval of any non-audit services to the Funds and its Service Affiliates if the Audit Committees believe that the provision of the service will not impair the independence of the auditor, is consistent with the SEC Rules on auditor independence, and otherwise conforms to the Audit Committees' general principles and policies as set forth herein. Audit-Related Services "Audit-related services" are assurance and related services that are reasonably related to the performance of the audit or review of the Fund's financial statements or that are traditionally performed by the independent auditor. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters not classified as "Audit services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; and agreed-upon procedures related to mergers, compliance with ratings agency requirements and interfund lending activities. Tax Services "Tax services" include, but are not limited to, the review and signing of the Funds' federal tax returns, the review of required distributions by the Funds and consultations regarding tax matters such as the tax treatment of new investments or the impact of new regulations. The Audit Committee will scrutinize carefully the retention of the Auditor in connection with a transaction initially recommended by the Auditor, the major business purpose of which may be tax avoidance or the tax treatment of which may not be supported in the Internal Revenue Code and related regulations. The Audit Committee will consult with the Funds' Treasurer (or his or her designee) and may consult with outside counsel or advisors as necessary to ensure the consistency of Tax services rendered by the Auditor with the foregoing policy. No Auditor shall represent any Fund or any Service Provider before a tax court, district court or federal court of claims. All Other Auditor Services The Audit Committees may pre-approve non-audit services classified as "All other services" that are not categorically prohibited by the SEC, as listed in Exhibit 1 to this policy. V. Pre-Approval Fee Levels or Established Amounts Pre-approval of estimated fees or established amounts for services to be provided by the Auditor under general or specific pre-approval policies will be set periodically by the Audit Committees. Any proposed fees exceeding 110% of the maximum estimated pre-approved fees or established amounts for pre-approved audit and non-audit services will be reported to the Audit Committees at the quarterly Audit Committees meeting and will require specific approval by the Audit Committees before payment is made. The Audit Committee will always factor in the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services and in determining whether to approve any additional fees exceeding 110% of the maximum pre-approved fees or established amounts for previously pre-approved services. VI. Procedures On an annual basis, A I M Advisors, Inc. ("AIM") will submit to the Audit Committees for general pre-approval, a list of non-audit services that the Funds or Service Affiliates of the Funds may request from the Auditor. The list will describe the non-audit services in reasonable detail and will include an estimated range of fees and such other information as the Audit Committee may request. Each request for services to be provided by the Auditor under the general pre-approval of the Audit Committees will be submitted to the Funds' Treasurer (or his or her designee) and must include a detailed description of the services to be rendered. The Treasurer or his or her designee will ensure that such services are included within the list of services that have received the general pre-approval of the Audit Committees. The Audit Committees will be informed at the next quarterly scheduled Audit Committees meeting of any such services for which the Auditor rendered an invoice and whether such services and fees had been pre-approved and if so, by what means. Each request to provide services that require specific approval by the Audit Committees shall be submitted to the Audit Committees jointly by the Fund's Treasurer or his or her designee and the Auditor, and must include a joint statement that, in their view, such request is consistent with the policies and procedures and the SEC Rules. Non-audit services pursuant to the de minimis exception provided by the SEC Rules will be promptly brought to the attention of the Audit Committees for approval, including documentation that each of the conditions for this exception, as set forth in the SEC Rules, has been satisfied. On at least an annual basis, the Auditor will prepare a summary of all the services provided to any entity in the investment company complex as defined in section 2-01(f)(14) of Regulation S-X in sufficient detail as to the nature of the engagement and the fees associated with those services. The Audit Committees have designated the Funds' Treasurer to monitor the performance of all services provided by the Auditor and to ensure such services are in compliance with these policies and procedures. The Funds' Treasurer will report to the Audit Committee on a periodic basis as to the results of such monitoring. Both the Funds' Treasurer and management of AIM will immediately report to the chairman of the Audit Committee any breach of these policies and procedures that comes to the attention of the Funds' Treasurer or senior management of AIM.
