7 Statutory Prospectus Supplement dated October 8, 2010 The purpose of this mailing is to provide you with changes to the current Statutory Prospectus for Institutional Class shares of the Funds listed below: Invesco Balanced-Risk Allocation Fund Invesco China Fund Invesco Developing Markets Fund Invesco Endeavor Fund Invesco Global Fund Invesco International Total Return Fund Invesco Japan Fund Invesco LIBOR Alpha Fund Invesco Small Companies Fund The following information replaces in its entirety the seventh paragraph appearing under the heading FUND SUMMARIES Invesco LIBOR Alpha Fund Principal Investment Strategies of the Fund : The Fund utilizes active duration and yield curve positioning for risk management and for generating alpha versus its benchmark. Duration is a measure of volatility expressed in years and represents the anticipated percent change in a bond s price at a single point in time for a 1% change in yield. As duration increases, volatility increases as applicable interest rates change. The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers then decide on risk factors to use in managing the Fund relative to that benchmark. In doing so, the portfolio managers consider recommendations from a team of specialists in positioning the Fund to generate alpha (specific factors affecting the return on s in excess of the benchmark). The portfolio managers generally rely upon a different team of specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. The portfolio managers rely on the specialists for adjusting the Fund s risk exposures and security selection. Decisions to purchase or sell securities are determined by the relative value considerations of the professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund s macro risk exposure (e.g. duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund s exposure to a particular security or issuer, degradation of an issuer s credit quality, or general liquidity needs of the Fund. The following information replaces in its entirety the tenth paragraph appearing under the heading INVESTMENT OBJECTIVES, STRATEGIES, RISKS AND PORTFOLIO HOLDINGS Objective and Strategies Invesco LIBOR Alpha Fund : The Fund utilizes active duration and yield curve positioning for risk management and for generating alpha versus its benchmark. Duration is a measure of volatility expressed in years and represents the anticipated percent change in a bond s price at a single point in time for a 1% change in yield. As duration increases, volatility increases as applicable interest rates change. The portfolio managers utilize an appropriate benchmark index in structuring the portfolio. The portfolio managers decide on appropriate risk factors such as sector and issuer weightings and duration relative to that benchmark. The portfolio managers then employ proprietary technology to calculate appropriate position sizes for each of these risk factors. In doing so, the portfolio managers consider recommendations from a globally interconnected team of specialist decision makers in positioning the Fund to generate alpha (specific factors affecting the return on s in excess of the benchmark). The portfolio managers generally rely upon a team of marketspecific specialists for trade execution and for assistance in determining the most efficient way (in terms of cost-efficiency and security selection) to implement those recommendations. Although a variety of specialists provide input in the management of the Fund, the portfolio managers retain responsibility for ensuring the Fund is positioned appropriately in terms of risk exposures and position sizes. Specialist decision makers employ a bottom-up approach to recommending larger or smaller exposure to specific risk factors. In general specialists will look for attractive risk-reward opportunities and securities that best enable the Fund to pursue those opportunities. The portfolio managers rely on these decision makers and market specific specialists for adjusting the Fund s risk exposures and security selection on a real-time basis using proprietary communication technology. Portfolio managers retain discretion for deciding how risk positions are implemented. Decisions to purchase or sell securities are determined by the relative value considerations of the professionals that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situationspecific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund s macro risk exposure (e.g. duration, yield, curve positioning, sector exposure), a need to limit or reduce the Fund s exposure to a particular security or issuer, degradation of an issuer s credit quality, or general liquidity needs of the Fund.

The Fund will also invest in the Subsidiary and exchange traded funds (ETFs) to gain exposure to commodity markets. The Subsidiary, in turn, will invest in futures, exchange traded notes (ETNs) and other securities and financially-linked instruments. ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy, minus applicable fees. ETNs are traded on an exchange (e.g., the New York Stock Exchange) during normal trading hours; however, investors can also hold the ETN until maturity. The Fund will generally maintain 60% of its assets in cash and cash equivalent instruments including affiliated money market Funds. Some of the cash holdings will serve as margin or collateral for the Fund s obligations under derivative transactions. The Fund s s in certain derivatives may create significant leveraged exposure to certain equity, fixed income and commodity markets. Leverage occurs when the s in derivatives create greater economic exposure than the amount invested. This means that the Fund could lose more than originally invested in the derivative. The Subsidiary is advised by the Adviser and has the same objective as the Fund and generally employs the same strategy but limits its s to commodity derivatives, ETNs, cash and cash equivalent instruments, including affiliated money market funds. The Subsidiary, unlike the Fund, may invest without limitation in commodities, commodity-linked derivatives and other securities, such as ETNs, that may provide leverage and non-leveraged exposure to commodity markets. The Subsidiary also may hold cash and invest in cash equivalent instruments, including affiliated money market funds, some of which may serve as margin or collateral for the Subsidiary s derivative positions. The Fund may invest up to 25% of its total assets in the Subsidiary. The Fund will be subject to the risks associated with any by the Subsidiary to the extent of the Fund s in the Subsidiary. The Fund is non-diversified, which means it can invest a greater percentage of its assets in any one issuer than a diversified fund can. Relative to traditional balanced portfolios, the Fund will seek to provide greater capital loss protection during down markets. The portfolio s management team will accomplish this through a three-step process. The first step involves asset selection. The management team selects representative assets to gain exposure to equity, fixed income and commodity markets. The selection process (1) evaluates a particular asset s theoretical case for long-term excess returns relative to cash; (2) screens the identified assets to meet minimum liquidity criteria; and (3) reviews the expected correlation among the assets and the expected risk for each asset to determine whether the selected assets are likely to improve the expected risk adjusted return of the Fund. The second step involves portfolio construction. Proprietary estimates for risk and correlation are used by the management team to create a portfolio. The team re-estimates the risk contributed by each asset and

14 re-optimizes the portfolio periodically or when new assets are introduced to the Fund. The final step involves active positioning. The management team actively adjusts portfolio positions to reflect the near-term market environment, while remaining consistent with the optimized long-term portfolio structure described in step two above. The management team balances these two competing ideas opportunity for excess return from active positioning and the need to maintain asset class exposure set forth in the optimized portfolio structure by setting controlled tactical ranges around the long-term asset allocation. The resulting asset allocation is then implemented by investing in derivatives, other financially-linked instruments, U.S. and foreign government debt securities, other securities, cash and cash equivalent instruments, including affiliated money market Funds. By using derivatives, the Fund is able to gain greater exposure to assets within each class than would be possible using cash instruments, and thus seeks to balance the amount of risk each asset class contributes to the portfolio. Principal Risks of Investing in the Fund The risks associated with an in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Market Risk. The prices of and the income generated by the Fund s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations. Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer s credit rating. Foreign Securities Risk. The Fund s foreign s will be affected by changes in the foreign country s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Developing Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments and lack of timely information than those in developed countries. Commodity Risk. The Fund or the Subsidiary may invest in commoditylinked derivative instruments, ETNs and exchange traded funds that may subject it to greater volatility. The Fund s concentration of its assets in a particular sector of the commodities markets may make it more susceptible to risks associated with those sectors. ETNs may pose risks associated with leverage, may be relatively illiquid, and may not be able to track the applicable market benchmark or strategy accurately. Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to risks associated with the Subsidiary s s, including derivatives and commodities. Because the Subsidiary is not registered under the Investment Company Act of 1940, the Fund, as the sole investor in the Subsidiary, will not have the protections offered to investors in registered companies. Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other s and may be subject to market, interest rate, credit, leverage, counterparty and management risks. A Fund investing in a derivative could lose more than the cash amount invested and incur higher taxes. Over the counter derivatives are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the Fund. Leverage Risk. Leverage created from borrowing or certain types of transactions or instruments, including derivatives, may impair the Fund s liquidity, cause it to liquidate positions at an unfavorable time, increase volatility or otherwise not achieve its intended objective. Exchange-Traded Funds Risk. An by an underlying fund in ETFs generally presents the same primary risks as an in a mutual fund. In addition, ETFs may be subject to the following: (1) a discount of the ETF s shares to its net asset value; (2) failure to develop an active trading market for the ETF s shares; (3) the listing exchange halting trading of the ETF s shares; (4) failure of the ETFs shares to track the referenced index; and (5) holding troubled securities in the referenced index. Counterparty Risk. Certain instruments may be subject to the risk that the other party to a contract will not fulfill its contractual obligations. Currency/Exchange Rate Risk. The dollar value of the Fund s foreign s will be affected by changes in the exchange rates between the dollar and the currencies in which those s are traded. Limited Number of Holdings Risk. The Fund may invest a large percentage of its assets in a limited number of securities, which could negatively affect the value of the Fund. Non-Diversification Risk. The Fund is non-diversified and can invest a greater portion of its assets in a single issuer. A change in the value of the issuer could affect the value of the Fund more than if it was a diversified fund. Active Trading Risk. The Fund may engage in frequent trading of portfolio securities resulting in a lower return and increased tax liability. Management Risk. The techniques and risk analysis used by the Fund s portfolio managers may produce the desired results. As with any mutual fund, loss of money is a risk of investing. An in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Performance Information No performance information is available for the Fund because it has not yet completed a full calendar year of operations. In the future, the Fund will disclose performance information in a bar chart and performance table. Such disclosure will give some indication of the risks of an in the Fund by comparing the Fund s performance with a broad measure of market performance and by showing changes in the Fund s performance from year to year.

AIM CHINA FUND Investment Objective The Fund s objective is long-term growth of capital. Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold Institutional Class shares of the Fund. Shareholder Fees (fees paid directly from your ) Institutional Class Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price) None Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, whichever is less) None Redemption/Exchange Fee (as a percentage of amount redeemed/exchanged) % Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your ) Institutional Class Management Fees 0.94% Distribution and/or Service (12b-1) Fees None Other Expenses 0.34 Acquired Fund Fees and Expenses 0.01 Total Annual Fund Operating Expenses You may be charged a 2.00% fee if you redeem or exchange shares of the Fund within 31 days of purchase. Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your has a 5% return each year and that the Fund s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be: 1 Year 3 Years 5 Years 10 Years Institutional Class $131 $409 $708 $1,556 Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund s performance. During the most recent fiscal year, the Fund s portfolio turnover rate was 98% of the average value of its portfolio. Principal Investment Strategies of the Fund The Fund seeks to meet its objective by investing, normally, at least 80% of its assets in a diversified portfolio of equity and equity-related transferable securities, including warrants and convertible securities, and/or debt securities of companies with substantial exposure to China (including the People s Republic of China, Hong Kong and Macau). Effective May 31, 2010 the preceding sentence will be replaced by the following: The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for purposes) in a diversified portfolio of issuers with substantial exposure to China (including the People s Republic of China, Hong Kong and Macau). The Fund will invest primarily in equity and equity-related transferable securities, including warrants and convertible securities, and/or debt securities. Under normal market conditions, the Fund does not expect to invest more than 25% of its net assets in -grade debt securities. In complying with the 80% requirement, the Fund may also invest in the following other s that have economic characteristics similar to the Fund s direct s: derivatives, exchange-traded funds (ETFs), American Depositary Receipts and participation notes. These derivatives and other s may have the effect of leveraging the Fund s portfolio. The Fund may invest up to 100% of its net assets in foreign securities. In selecting securities to buy and sell, the Fund s portfolio managers will apply an actively managed bottom-up fundamental analysis and top down multi-factor analysis that blends both growth at a reasonable price and value-oriented disciplines. In the security selection process, the portfolio managers will consider four main factors, including valuation, management/franchise value determination (including management and ownership, earnings quality, balance sheet quality and product quality), earnings growth, and liquidity. The portfolio managers will consider whether to sell a particular security when the security trades significantly above its estimated fair value, when there is a permanent, fundamental deterioration in business prospects or when a more attractive opportunity is identified. 4 AIM Investment Funds

16 Principal Risks of Investing in the Fund The risks associated with an in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Market Risk. The prices of and the income generated by the Fund s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations. Small- and Mid-Capitalization Risk. Equity securities prices change to differing degrees based on the issuer s market capitalization in response to such factors as historical and prospective issuer earnings and asset values, economic conditions, interest rates, investor perceptions and market liquidity. Foreign Securities Risk. The Fund s foreign s will be affected by changes in the foreign country s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Geographic Concentration Risk. Because the Fund s s are concentrated in China, the Fund s performance is expected to be closely tied to social, political, and economic conditions within China and to be more volatile than the performance of more geographically diversified funds. Developing Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments and lack of timely information than those in developed countries. Unique Economic and Political Risks of Investing in China. China remains a totalitarian country with the following risks: nationalization, expropriation, or confiscation of property; difficulty in obtaining and/or enforcing judgments; alteration or discontinuation of economic reforms; military conflicts, either internal or with other countries; inflation, currency fluctuations and fluctuations in inflation and interest rates that may have negative effects on the economy and securities markets of China; and China s dependency on the economies of other Asian countries, many of which are developing countries. Risks of Purchasing A Shares of Chinese Companies. A shares of Chinese companies or participation notes designed to replicate them may be illiquid or subject to minimum and maximum regulations or repatriation restrictions. Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer s credit rating. Exchange-Traded Funds Risk. An by an underlying fund in ETFs generally presents the same primary risks as an in a mutual fund. In addition, ETFs may be subject to the following: (1) a discount of the ETF s shares to its net asset value; (2) failure to develop an active trading market for the ETF s shares; (3) the listing exchange halting trading of the ETF s shares; (4) failure of the ETFs shares to track the referenced index; and (5) holding troubled securities in the referenced index. Currency/Exchange Rate Risk. The dollar value of the Fund s foreign s will be affected by changes in the exchange rates between the dollar and the currencies in which those s are traded. Limited Number of Holdings Risk. The Fund may invest a large percentage of its assets in a limited number of securities, which could negatively affect the value of the Fund. Management Risk. The techniques and risk analysis used by the Fund s portfolio managers may produce the desired results. Initial Public Offerings Risk. The prices of Initial Public Offering (IPO) securities fluctuate more than prices of equity securities of companies with longer trading histories. In addition, companies offering securities in IPOs may have less experienced management or limited operating histories. There can be no assurance that the Fund will have favorable IPO opportunities. Active Trading Risk. The Fund may engage in frequent trading of portfolio securities resulting in a lower return and increased tax liability. As with any mutual fund, loss of money is a risk of investing. An in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Performance Information The bar chart and performance table provide an indication of the risks of investing in the Fund. The performance table compares the Fund s performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark with similar objectives to the Fund. The benchmarks may not reflect payment of fees, expenses or taxes. The Fund is not managed to track the performance of any particular benchmark, including the benchmarks shown below, and consequently, the performance of the Fund may deviate significantly from the performance of these benchmarks. The Fund s past performance (before and after taxes) is not necessarily an indication of its future performance. Updated performance information is available at Effective April 30, 2010, will be changed to Annual Total Returns The bar chart shows changes in the performance of the Fund from year to year as of December 31.

Actual after-tax returns depend on an investor s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The Fund has elected to use the MSCI China 10/40 Index as its style specific benchmark instead of the MSCI China Index because it will better align the Fund s style specific benchmark with its processes and restrictions. 5 AIM Investment Funds

During the most recent fiscal year, the Fund s portfolio turnover rate was 28% of the average value of its portfolio. Principal Investment Strategies of the Fund The Fund invests, under normal circumstances, at least 80% of net assets (plus borrowings for purposes) in securities issued by foreign companies and governments that are in developing markets countries i.e., those that are in the initial stages of their industrial cycles. The Fund invests primarily in equity securities. In complying with the 80% requirement, the Fund may also invest in the following other s that have economic characteristics similar to the Fund s direct s: derivatives, exchange traded funds (ETFs) and American Depositary Receipts. These derivatives and other instruments may have the effect of leveraging the Fund s portfolio. The Fund invests, under normal circumstances, in issuers located in at least three countries outside of the U.S., but it will invest no more than 25% of its total assets in issuers in any one country. As of February 23, 2010, the principal countries in which the Fund invests are Brazil, Philippines, Hong Kong, Indonesia, Republic of Korea, Malaysia, Thailand and Turkey. The Fund may hold no more than 40% of its total assets in any one foreign currency and securities denominated in or indexed to 6 AIM Investment Funds

18 such currency. The Fund may invest in debt securities when economic and other factors appear to favor such s. The Fund may also invest up to 50% of its total assets in lower-quality debt securities, i.e., high yield bonds or junk bonds. The Fund may invest up to 50% of its total assets in the following types of developing market debt securities: (1) debt securities issued or guaranteed by governments, their agencies, instrumentalities or political subdivisions, or by government owned, controlled or sponsored entities, including central banks (sovereign debt), and Brady Bonds ; (2) interests in issuers organized and operated for the purpose of restructuring the characteristics of sovereign debt; (3) debt securities issued by banks and other business entities; and (4) debt securities denominated in or indexed to the currencies of emerging markets. Brady Bonds are debt restructurings that provide for the exchange of cash and loans for newly issued bonds. There is no requirement with respect to the maturity or duration of debt securities in which the Fund may invest. The Fund is non-diversified, which means it can invest a greater percentage of its assets in any one issuer than a diversified Fund can. The portfolio managers employ a disciplined strategy that emphasizes fundamental research, supported by quantitative analysis, portfolio construction and risk management techniques. The strategy primarily focuses on identifying issuers that have experienced, or exhibit the potential for, accelerating or above average earnings growth but whose prices do not fully reflect these attributes. Investments for the portfolio are selected bottom-up on a security-by-security basis. The focus is on the strengths of individual issuers, rather than sector or country trends. The Fund s portfolio managers may consider selling a security for several reasons, including when, (1) its fundamentals deteriorate or it posts disappointing earnings; (2) its security price appears to be overvalued; or (3) a more attractive opportunity is identified. Principal Risks of Investing in the Fund The risks associated with an in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Market Risk. The prices of and the income generated by the Fund s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations. Small-and Mid-Capitalization Risk. Stocks of small and mid sized companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of small and mid sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price. Foreign Securities Risk. The Fund s foreign s will be affected by changes in the foreign country s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Developing Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments and lack of timely information than those in developed countries. Exchange-Traded Funds Risk. An by an underlying fund in ETFs generally presents the same primary risks as an in a mutual fund. In addition, ETFs may be subject to the following: (1) a discount of the ETF s shares to its net asset value; (2) failure to develop an active trading market for the ETF s shares; (3) the listing exchange halting trading of the ETF s shares; (4) failure of the ETFs shares to track the referenced index; and (5) holding troubled securities in the referenced index. High Yield Bond Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time. Non-Diversification Risk. The Fund is non-diversified and can invest a greater portion of its assets in a single issuer. A change in the value of the issuer could affect the value of the Fund more than if it was a diversified fund. Management Risk. The techniques and risk analysis used by the Fund s portfolio managers may produce the desired results. As with any mutual fund, loss of money is a risk of investing.

Shareholder Fees (fees paid directly from your ) Institutional Class Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price) None Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, whichever is less) None Redemption/Exchange Fee (as a percentage of amount redeemed/exchanged) % Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your ) Institutional Class Management Fees 0.65% Distribution and/or Service (12b-1) Fees None Other Expenses 0.36 Total Annual Fund Operating Expenses 1.01 Fee Waiver and/or Expense Reimbursement Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement AIM Investment Funds 1 You may be charged a 2.00% fee if you redeem or exchange shares of the Fund within 31 days of purchase. 2 The Adviser has contractually agreed, through at least February 28, 2011, to waive advisory fees and/or reimburse expenses of all shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Institutional Class shares to 0.85% of average daily net assets. In determining the Adviser 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 After Fee Waiver and/or Expense Reimbursement to exceed the numbers reflected above: (1) interest; (2) taxes; (3) dividend expense on short sales; (4) extraordinary or non-routine items; and (5) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. The Board of Trustees and Invesco Advisers, Inc. may mutually agree to terminate the fee waiver arrangements at any time. Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your has a 5% return each year and that the Fund s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be: 1 Year 3 Years 5 Years 10 Years Institutional Class $87 $306 $542 $1,222 Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or turns over its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund s performance. During the most recent fiscal year, the Fund s portfolio turnover rate was 233% of the average value of its portfolio.

20 Principal Investment Strategies of the Fund The Fund seeks to meet its objective by investing, normally, at least 80% of its net assets, plus the amount of any borrowings for purposes, in a diversified portfolio of foreign government and corporate debt securities, generally represented by the sector categories within the Barclays Capital Global Aggregate ex U.S. Index (unhedged), and in foreign currency s. Effective May 31, 2010, the preceding sentence will be replaced by the following: The Fund invests its assets in a diversified portfolio of foreign government and corporate debt securities, generally represented by the sector categories within the Barclays Capital Global Aggregate ex U.S. Index (unhedged), and in foreign currency s. Debt securities that the Fund may invest in include foreign sovereign, corporate or agency securities of varying maturities, including securitized securities, such as asset-backed and mortgage-backed securities, and commercial paper and other short-term debt instruments. The Fund may invest in derivatives, including swaps, options, and futures contracts. The Fund may also utilize other strategies such as dollar rolls and reverse repurchase agreements. Derivative instruments, dollar rolls and reverse purchase agreements may have the effect of leveraging the Fund s portfolio. Foreign currency s may include spot contracts, forward currency contracts, currency swaps, currency options, currency futures and options on currency futures. The Fund may invest up to 30% of its total assets in U.S. dollardenominated securities. The Fund may invest up to 25% of its total assets in non- grade securities (junk bonds), including non- grade emerging market securities. The Fund will use the Barclays Capital Global Aggregate ex U.S. Index (unhedged) (its benchmark index) as a guide in structuring and selecting its s, but will seek to outperform such index by applying an actively managed top-down portfolio construction and bottom-up security selection total return strategy. The Fund seeks to outperform its benchmark through an analysis of a variety of alpha sources (specific factors affecting the return on s in excess of the benchmark), including, among others, interest rate and yield curve risk, high yield and emerging market risk, country risk and currency risk. In constructing the portfolio, the portfolio managers will consider macro-economic and sector level factors such as economic or political conditions, monetary policy, and emerging markets, as well as issuer specific factors such as cash flow coverage, revenue growth, stable or improving credit ratings and business margin improvement. The portfolio managers focus on securities that they believe have favorable prospects for exceeding the benchmark. The portfolio managers may adjust the split between sovereign, agency and corporate bonds in the Fund depending on their assessment of overall market conditions. The portfolio managers will consider whether to sell a particular security when the risk factors relative to return materially change. Principal Risks of Investing in the Fund The risks associated with an in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Market Risk. The prices of and the income generated by the Fund s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations. Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer s credit rating. Foreign Securities Risk. The Fund s foreign s will be affected by changes in the foreign country s exchange rates; political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Developing Markets Securities Risk. Securities issued by foreign companies and governments located in developing countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments and lack of timely information than those in developed countries. High Yield Bond Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time. Mortgage- and Asset-Backed Securities Risk. The Fund may invest in mortgage and asset-backed securities that are subject to prepayment or call risk, which is the risk that the borrower s payments may be received earlier or later than expected due to changes in the prepayment rates on the underlying loans. Securities may be prepaid at a price less than the original purchase value. Derivatives Risk. Derivatives may be more difficult to purchase, sell or value than other s and may be subject to market, interest rate, credit, leverage, counterparty and management risks. A Fund investing in a derivative could lose more than the cash amount invested and incur higher taxes. Over the counter derivatives are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the Fund. Leverage Risk. Leverage created from borrowing or certain types of transactions or instruments, including derivatives, may impair the Fund s liquidity, cause it to liquidate positions at an unfavorable time, increase volatility or otherwise not achieve its intended objective. Currency/Exchange Rate Risk. The dollar value of the Fund s foreign s will be affected by changes in the exchange rates between the dollar and the currencies in which those s are traded. Limited Number of Holdings Risk. The Fund may invest a large percentage of its assets in a limited number of securities, which could negatively affect the value of the Fund. Active Trading Risk. The Fund may engage in frequent trading of portfolio securities resulting in a lower return and increased tax liability. Management Risk. The techniques and risk analysis used by the Fund s portfolio managers may produce the desired results. As with any mutual fund, loss of money is a risk of investing. An in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Performance Information The bar chart and performance table provide an indication of the risks of investing in the Fund. The performance table compares the Fund s performance to that of a broad-based securities market benchmark and a peer group benchmark with similar objectives to the Fund. The benchmarks may not reflect payment of fees, expenses or taxes. The Fund is not managed to track the performance of any particular benchmark, including the benchmarks shown below, and consequently, the performance of the Fund may deviate significantly from the performance of these benchmarks. The Fund s past performance (before and after taxes) is not necessarily an indication of its future performance.
