- LIQUID ASSETS PORTFOLIO Investment Objective(s) The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) December 31, 2013 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 investment 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: Principal Investment Strategies of the Fund The Fund invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes. The Fund may engage in repurchase agreement transactions that are collateralized by cash or government securities. In addition, it may engage in repurchase agreement transactions that are collateralized by nongovernment securities such as equity securities and securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with Security and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term rating category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers manage liquidity, for instance, by trading in daily and weekly variable-rate demand notes. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. Principal Risks of Investing in the Fund Fund Summaries - GOVERNMENT TAXADVANTAGE PORTFOLIO Investment Objective(s) The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. Fees and Expenses of the Fund As with any mutual fund investment, loss of money is a risk of investing. An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Foreign Securities Risk. The value of the Fund’s foreign investments may be adversely affected by 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. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights. <div style="display:none">~ http://www.invesco.com/role/ScheduleShareholderFeesGovernmentTaxAdvantagePortfolio column period compact * ~</div> Example. 1998-09-01 The bar chart and performance table provide an indication of the risks of investing in the Fund.

Agency Securities may be supported by (i) the full faith and credit of the U.S. Treasury; (ii) the right of the issuer to borrow from the U.S. Treasury; (iii) the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; or (iv) the credit of the agency or instrumentality. At the present time, the Fund has no current intention to invest in securities other than direct obligations of the U.S. Treasury and Agency Securities. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term rating category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. 0.0028 The bar chart and performance table provide an indication of the risks of investing in the Fund.

As with any mutual fund investment, loss of money is a risk of investing. An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights. The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity.

Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Shareholder Fees (fees paid directly from your investment) Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 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 investment 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: Average Annual Total Returns (for the periods ended December 31, 2011) Principal Investment Strategies of the Fund The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes. The Fund may engage in repurchase agreement transactions that are collateralized by cash or government securities. In addition, it may engage in repurchase agreement transactions that are collateralized by nongovernment securities such as equity securities and securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term rating category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. The Fund may purchase delayed delivery and when-issued securities that have a maturity of up to 60 days, calculated from settlement date. The Fund may also invest in securities whether or not considered foreign securities, which carry foreign credit exposure. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers manage liquidity, for instance, by trading in daily and weekly variable-rate demand notes. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. Principal Risks of Investing in the Fund As with any mutual fund investment, loss of money is a risk of investing. An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

The portfolio managers manage liquidity, for instance, by trading in daily and weekly variable-rate demand notes. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. 14 54 Principal Risks of Investing in the Fund 97 226 <div style="display:none">~ http://www.invesco.com/role/ScheduleShareholderFeesGovernmentAndAgencyPortfolioInstitutional column period compact * ~</div> <div style="display:none">~ http://www.invesco.com/role/ScheduleAverageAnnualTotalReturnsTransposedSTICPrimePortfolioPersonalInvestment column period compact * ~</div> <div style="display:none">~ http://www.invesco.com/role/ScheduleExpenseExampleTransposedGovernmentTaxAdvantagePortfolioInstitutional column period compact * ~</div> This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights. 2007-09-30 0.0131 Performance Information Worst Quarter 2011-12-31 <div style="display:none">~ http://www.invesco.com/role/ScheduleShareholderFeesTAX-FREECASHRESERVEPORTFOLIO column period compact * ~</div> 0.0001 The bar chart and performance table provide an indication of the risks of investing in the Fund.

The value of the Fund’s foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility.

The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund invests primarily in high quality U.S. dollar-denominated short-term debt obligations, including: (i) municipal securities; (ii) tax-exempt commercial paper; and (iii) cash equivalents. These securities may have credit and liquidity enhancements provided by banks, insurance companies or other financial institutions. Municipal securities include debt obligations of states, territories and possessions of the United States and the District of Columbia, their political subdivisions, agencies and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Municipal lease obligations, synthetic municipal securities and certain types of industrial revenue bonds are treated as municipal securities. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party demand feature, are treated as municipal securities. Other securities held by the Fund may be structured with demand features which have the effect of shortening the security’s maturity. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments.

Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term rating category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. The Fund may also invest in securities whether or not considered foreign securities, which carry foreign credit exposure. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

Agency Securities may be supported by (i) the full faith and credit of the U.S. Treasury; (ii) the right of the issuer to borrow from the U.S. Treasury; (iii) the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; or (iv) the credit of the agency or instrumentality. At the present time, the Fund has no current intention to invest in securities other than direct obligations of the U.S. Treasury and Agency Securities, as well as repurchase agreements secured by those obligations. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term ratings category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. 2012-09-30 As with any mutual fund investment, loss of money is a risk of investing.

The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations.

Principal Risks of Investing in the Fund As with any mutual fund investment, loss of money is a risk of investing. An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Foreign Securities Risk. The value of the Fund’s foreign investments may be adversely affected by 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. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk.

Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk.

Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights. <div style="display:none">~ http://www.invesco.com/role/ScheduleExpenseExampleTransposedLiquidAssetsPortfolioCorporate column period compact * ~</div> The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity.

The Fund invests primarily in high quality U.S. dollar-denominated short-term debt obligations, including: (i) municipal securities; (ii) tax-exempt commercial paper; and (iii) cash equivalents. These securities may have credit and liquidity enhancements provided by banks, insurance companies or other financial institutions. Municipal securities include debt obligations of states, territories and possessions of the United States and the District of Columbia, their political subdivisions, agencies and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Municipal lease obligations, synthetic municipal securities and certain types of industrial revenue bonds are treated as municipal securities. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party demand feature, are treated as municipal securities. Other securities held by the Fund may be structured with demand features which have the effect of shortening the security’s maturity.

Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities.

The Fund may engage in repurchase agreement transactions that are collateralized by cash or government securities. In addition, it may engage in repurchase agreement transactions that are collateralized by nongovernment securities such as equity securities and securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with Security and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term rating category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers manage liquidity, for instance, by trading in daily and weekly variable-rate demand notes. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. Annual Total Returns December 31, 2013 <div style="display:none">~ http://www.invesco.com/role/ScheduleAnnualFundOperatingExpensesGovernmentTaxAdvantagePortfolioPersonalInvestment column period compact * ~</div> The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities, the interest of which is excluded from gross income for federal income tax purposes and does not constitute an item of preference for purposes of the alternative minimum tax. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund invests primarily in high quality U.S. dollar-denominated short-term debt obligations, including: (i) municipal securities; (ii) tax-exempt commercial paper; and (iii) cash equivalents. These securities may have credit and liquidity enhancements provided by banks, insurance companies or other financial institutions. Municipal securities include debt obligations of states, territories and possessions of the United States and the District of Columbia, their political subdivisions, agencies and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Municipal lease obligations, synthetic municipal securities and certain types of industrial revenue bonds are treated as municipal securities. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party demand feature, are treated as municipal securities. Other securities held by the Fund may be structured with demand features which have the effect of shortening the security’s maturity. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent.

The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Foreign Securities Risk. The value of the Fund’s foreign investments may be adversely affected by 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. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights. <div style="display:none">~ http://www.invesco.com/role/ScheduleExpenseExampleTransposedGovernmentTaxAdvantagePortfolioPersonalInvestment column period compact * ~</div> 114 1999-01-04 Institutional Class year-to-date (ended September 30, 2012): 0.02% Best Quarter (ended December 31, 2006): 1.30% Worst Quarter (ended December 31, 2009 through June 30, 2010 and December 31, 2010 through December 31, 2011): 0.01% 2005-03-29 394 696 1552 <div style="display:none">~ http://www.invesco.com/role/ScheduleAnnualTotalReturnsGovernmentTaxAdvantagePortfolioPersonalInvestmentBarChart column period compact * ~</div> 0.0003 Money Market Fund Risk.

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 investment 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: Principal Investment Strategies of the Fund The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in direct obligations of the U.S. Treasury and other securities issued or guaranteed as to principal and interest by the U.S. Government or its agencies and instrumentalities (Agency Securities), as well as repurchase agreements secured by those obligations. Agency Securities may be supported by (i) the full faith and credit of the U.S. Treasury; (ii) the right of the issuer to borrow from the U.S. Treasury; (iii) the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; or (iv) the credit of the agency or instrumentality. At the present time, the Fund has no current intention to invest in securities other than direct obligations of the U.S. Treasury and Agency Securities, as well as repurchase agreements secured by those obligations. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term ratings category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. Principal Risks of Investing in the Fund As with any mutual fund investment, loss of money is a risk of investing. An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default.

Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk.

Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights.

The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. An investment 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 governmental agency. The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The Fund’s past performance is not necessarily an indication of its future performance. Updated performance information is available on the Fund’s Web site at www.invesco.com/us. The Fund invests in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) bankers’ acceptances, certificates of deposit, and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; (v) municipal securities; and (vi) master notes. The Fund may engage in repurchase agreement transactions that are collateralized by cash or government securities. In addition, it may engage in repurchase agreement transactions that are collateralized by nongovernment securities such as equity securities and securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with Security and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940 of no more than 120 days. Each investment must be determined to present minimal credit risks by the Fund’s Adviser pursuant to guidelines approved by the Fund’s Board of Trustees, and must be an “Eligible Security” as defined under applicable regulations. First Tier Securities generally means Eligible Securities rated within the highest short-term rating category, an unrated security of comparable quality as determined by the Adviser under the supervision of the Board of Trustees, U.S. Government Securities as defined by applicable regulations, and securities issued by other registered money market funds. The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers manage liquidity, for instance, by trading in daily and weekly variable-rate demand notes. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change.

An investment 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 governmental agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. Counterparty Risk. Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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 Credit Exposure Risk. U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest. Foreign Securities Risk. The value of the Fund’s foreign investments may be adversely affected by 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. Industry Focus Risk. To the extent the Fund invests in securities issued or guaranteed by companies in the banking and financial services industries, the Fund’s performance will depend on the overall condition of those industries, which may be affected by the following factors: the supply of short-term financing, changes in government regulation and interest rates, and the overall economy. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Municipal Securities Risk. The Fund may invest in municipal securities. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell it. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of the instruments, and a portfolio could suffer a loss if the issuer defaults during periods in which a portfolio is not entitled to exercise its demand rights. An investment 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 governmental agency.

The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund invests primarily in high quality U.S. dollar-denominated short-term debt obligations, including: (i) municipal securities; (ii) tax-exempt commercial paper; and (iii) cash equivalents. These securities may have credit and liquidity enhancements provided by banks, insurance companies or other financial institutions. Municipal securities include debt obligations of states, territories and possessions of the United States and the District of Columbia, their political subdivisions, agencies and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Municipal lease obligations, synthetic municipal securities and certain types of industrial revenue bonds are treated as municipal securities. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party demand feature, are treated as municipal securities. Other securities held by the Fund may be structured with demand features which have the effect of shortening the security’s maturity. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments.

The Fund may also invest in securities whether or not considered foreign securities, which carry foreign credit exposure.

The Adviser conducts a credit analysis of each potential issuer prior to the purchase of its securities. The portfolio managers manage liquidity, for instance, by trading in daily and weekly variable-rate demand notes. The portfolio structure is driven to some extent by the supply and availability of municipal obligations. The portfolio managers normally hold portfolio securities to maturity, but may sell a security when they deem it advisable, such as when market or credit factors materially change. Principal Risks of Investing in the Fund As with any mutual fund investment, loss of money is a risk of investing. An investment 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 governmental agency.

The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk.

Counterparty risk is the risk that the other party to the contract will not fulfill its contractual obligations, which may cause losses or additional costs to the Fund. 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.

Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

Agency Securities may be supported by (i) the full faith and credit of the U.S. Treasury; (ii) the right of the issuer to borrow from the U.S. Treasury; (iii) the discretionary authority of the U.S. Government to purchase certain obligations of the agency or instrumentality; or (iv) the credit of the agency or instrumentality. At the present time, the Fund has no current intention to invest in securities other than direct obligations of the U.S. Treasury and Agency Securities. The Fund will limit investments to those securities that are First Tier Securities (defined below) at the time of purchase. The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states. The Fund is a money market fund that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar denominated securities maturing within 397 days of the date of purchase, with certain exceptions permitted by applicable regulations.

Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Cash/Cash Equivalents Risk. Holding cash or cash equivalents may negatively affect performance. 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. Liquidity Risk. The Fund may hold illiquid securities that it may be unable to sell at the preferred time or price and could lose its entire investment in such securities. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. 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 interest rate fluctuations. Money Market Fund Risk. Although the Fund seeks to preserve the value of your investment at $1.00 per share, you may lose money by investing in the Fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the Fund’s $1.00 share price. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. Further regulation could impact the way the Fund is managed, possibly negatively impacting its return. Additionally, the Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. U.S. Government Obligations Risk. The Fund may invest in obligations issued by U.S. Government agencies and instrumentalities that may receive varying levels of support from the government, which could affect the Fund’s ability to recover should they default. <div style="display:none">~ http://www.invesco.com/role/ScheduleAnnualTotalReturnsTreasuryPortfolioResourceBarChart column period compact * ~</div> Money Market Fund Risk.
