Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Cash Management Class shares to 0.26%, of the Fund's average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2022. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.
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.

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Cash Management Class shares to 0.26%, of the Fund's average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2022. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.
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 equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Principal Investment Strategies of the Fund
The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities.
The Fund invests in conformity with U.S. Securities 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 60 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 60 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other
factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
4        Short-Term Investment Trust

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.

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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors.

The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value.

The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as
8        Short-Term Investment Trust

real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.
The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board of Trustees, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns
10        Short-Term Investment Trust

over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

In addition, it may engage in repurchase agreement transactions that are collateralized by nongovernment securities such as equity securities and fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax
developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Government & Agency Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested, under normal circumstances, 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, as well as repurchase agreements secured by those obligations. Direct obligations of the U.S. Treasury generally include bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.

Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time.

Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk.

Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Risks
The principal risks of investing in the Fund are:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio , after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.02% of Invesco Treasury Obligations Portfolio's average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco Tax-Free Cash Reserve Portfolio , after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Other Information
Dividends and Distributions
Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio expect, based on their investment objective and strategies, that their dividends and distributions, if any, will consist primarily of ordinary income.
Invesco Tax-Free Cash Reserve Portfolio expects, based on its investment objective and strategies, that its dividends and distributions, if any, will consist primarily of tax-exempt income.
Dividends
Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio generally declare dividends, if any, daily and pay them monthly.
Dividends are paid on settled shares of the Invesco Treasury Portfolio and Invesco Government & Agency Portfolio as of 5:30 p.m. Eastern Time, Invesco Tax-Free Cash Reserve Portfolio as of 4:00 p.m. Eastern Time and Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio and Invesco Treasury Obligations Portfolio as of 3:00 p.m. Eastern Time (“Settlement Time”). If a Fund closes early on a business day, such Fund will pay dividends on settled shares at such earlier closing time. Generally, shareholders whose purchase orders have been accepted by the Funds prior to the respective Fund’s Settlement Time, or an earlier close time on any day that a Fund closes early, are eligible to receive dividends on that business day. The dividend declared on any day preceding a non-business day or days of a Fund will include the net income accrued on such non-business day or days. Dividends and distributions are reinvested in the form of additional full and fractional shares at net asset value unless the shareholder has elected to have such dividends and distributions paid in cash. See “Pricing of Shares -Timing of Orders” for a description of the Fund’s business days.
Capital Gains Distributions
Each Fund generally distributes net realized capital gains (including net short-term capital gains), if any, at least annually. Each Fund does not expect to realize any long-term capital gains and losses.

Financial Highlights
The financial highlights table is intended to help you understand each Fund’s financial performance for the past five years of the Cash Management Class shares. Certain information reflects financial results for a single Fund share.
The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions).
This information has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with a Fund’s financial statements, is included in each Fund’s annual report, which is available upon request.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■

Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
A-5        The Invesco Funds

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
Invesco Tax-Free Cash Reserve Portfolio
■ 
You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not
4        Short-Term Investment Trust

be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
6        Short-Term Investment Trust

Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
7        Short-Term Investment Trust

The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited
8        Short-Term Investment Trust

information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or
economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience
9        Short-Term Investment Trust

losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.

Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency

rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry.

The share price of money market funds can fall below the $1.00 share price. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as
changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds’ portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.

A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/cavu.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio's average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio's average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio's average daily net assets, after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Other Information
Dividends and Distributions
Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio expect, based on their investment objective and strategies, that their dividends and distributions, if any, will consist primarily of ordinary income.
Dividends
Invesco Liquid Assets Portfolio, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio generally declare dividends, if any, daily and pay them monthly.
Dividends are paid on settled shares of the Invesco Treasury Portfolio and Invesco Government & Agency Portfolio as of 5:30 p.m. Eastern Time, and Invesco Liquid Assets Portfolio as of 3:00 p.m. Eastern Time (“Settlement Time”). If a Fund closes early on a business day, such Fund will pay dividends on settled shares at such earlier closing time. Generally, shareholders whose purchase orders have been accepted by the Funds prior to the respective Fund’s Settlement Time, or an earlier close time on any day that a Fund closes early, are eligible to receive dividends on that business day. The dividend declared on any day preceding a non-business day or days of a Fund will include the net income accrued on such non-business day or days. Dividends and distributions are reinvested in the form of additional full and fractional shares at net asset value unless the shareholder has elected to have such dividends and distributions paid in cash. See “Pricing of Shares -Timing of Orders” for a description of the Fund’s business days.
Capital Gains Distributions
Each Fund generally distributes net realized capital gains (including net short-term capital gains), if any, at least annually. Each Fund does not expect to realize any long-term capital gains and losses.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

If a Fund exercises its discretion to close early on a business day, as described in the “Pricing of Shares—Timing of Orders” section of this prospectus, the Fund may not provide same day settlement of redemption orders.
Dividends payable up to the date of redemption on redeemed shares will normally be paid or reinvested on the next dividend payment date. However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Liquid Assets Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets fall below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the
A-2        The Invesco Funds—CAVU Securities Class

fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the
redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Liquid Assets Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares) provided you meet the eligibility criteria of such other share classes, but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage
A-3        The Invesco Funds—CAVU Securities Class

of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the
basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio and Invesco Government & Agency Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
A-4        The Invesco Funds—CAVU Securities Class

■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio round its current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of the Fund calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes.
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S. taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is
A-5        The Invesco Funds—CAVU Securities Class

inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents
To reduce Fund expenses, only one copy of most shareholder documents may be mailed to shareholders with multiple accounts at the same address (Householding). Mailing of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please contact the Funds’ transfer agent at 800-659-1005 or contact your financial institution. The Funds’ transfer agent will begin sending you individual copies for each account within thirty days after receiving your request.

nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to
6        Short-Term Investment Trust

repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7, under the Investment Company Act of 1940, as amended (Rule 2a-7) 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Corporate Class shares to 0.23%, of the Fund's average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2022. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.
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 equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits
13        Short-Term Investment Trust

from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general
16        Short-Term Investment Trust

outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence,
17        Short-Term Investment Trust

increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well,
21        Short-Term Investment Trust

there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Risks
The principal risks of investing in the Fund are:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio , after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.

During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco Tax-Free Cash Reserve Portfolio , after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
For Invesco Treasury Portfolio and Invesco Government & Agency Portfolio, the Funds’ transfer agent will normally wire payment for redemptions received prior to 5:30 p.m. Eastern Time on the business day received, and in any event no more than seven days, after your redemption request is received in good order. However, depending on such factors as market liquidity and the size of the redemption, for a redemption request received by the Funds’ transfer agent between 5:00 p.m. Eastern Time and 5:30 p.m. Eastern Time, proceeds may not be wired until the next business day. If the Funds’ transfer agent receives a redemption request on a business day after 5:30 p.m. Eastern Time, the redemption will be effected at the net asset value of each Fund determined on the next business day, and the Funds’ transfer agent will normally wire redemption proceeds on such next business day, and in any event no more than seven days, after your redemption request is received in good order.
If a Fund exercises its discretion to close early on a business day, as described in the “Pricing of Shares—Timing of Orders” section of this prospectus, the Fund may not provide same day settlement of redemption orders.
Dividends payable up to the date of redemption on redeemed shares will normally be paid or reinvested on the next dividend payment date.

Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares), but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
A-5        The Invesco Funds

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.

You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to
6        Short-Term Investment Trust

repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

The Fund invests at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board of Trustees, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns
10        Short-Term Investment Trust

over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits
13        Short-Term Investment Trust

from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco STIC Prime Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 60 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 60 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers
factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general
16        Short-Term Investment Trust

outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence,
17        Short-Term Investment Trust

increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.

If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
18        Short-Term Investment Trust

Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.

Invesco Government & Agency Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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.

In addition, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested, under normal circumstances, 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, as well as repurchase agreements secured by those obligations. Direct obligations of the U.S. Treasury generally include bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.

The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.

For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency
rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Invesco Treasury Obligations Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.
The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. In addition, 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, which include Treasury bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions.

Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Risks
The principal risks of investing in the Fund are:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.

During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco Tax-Free Cash Reserve Portfolio, after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Other Information
Dividends and Distributions
Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio expect, based on their investment objective and strategies, that their dividends and distributions, if any, will consist primarily of ordinary income.
Invesco Tax-Free Cash Reserve Portfolio expects, based on its investment objective and strategies, that its dividends and distributions, if any, will consist primarily of tax-exempt income.
Dividends
Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio generally declare dividends, if any, daily and pay them monthly.
Dividends are paid on settled shares of the Invesco Treasury Portfolio and Invesco Government & Agency Portfolio as of 5:30 p.m. Eastern Time, Invesco Tax-Free Cash Reserve Portfolio as of 4:00 p.m. Eastern Time and Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio and Invesco Treasury Obligations Portfolio as of 3:00 p.m. Eastern Time (“Settlement Time”). If a Fund closes early on a business day, such Fund will pay dividends on settled shares at such earlier closing time. Generally, shareholders whose purchase orders have been accepted by the Funds prior to the respective Fund’s Settlement Time, or an earlier close time on any day that a Fund closes early, are eligible to receive dividends on that business day. The dividend declared on any day preceding a non-business day or days of a Fund will include the net income accrued on such non-business day or days. Dividends and distributions are reinvested in the form of additional full and fractional shares at net asset value unless the shareholder has elected to have such dividends and distributions paid in cash. See “Pricing of Shares -Timing of Orders” for a description of the Fund’s business days.
Capital Gains Distributions
Each Fund generally distributes net realized capital gains (including net short-term capital gains), if any, at least annually. Each Fund does not expect to realize any long-term capital gains and losses.

Financial Highlights
The financial highlights table is intended to help you understand each Fund’s financial performance for the past five years of the Institutional Class shares. Certain information reflects financial results for a single Fund share.
The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions).
This information has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with a Fund’s financial statements, is included in each Fund’s annual report, which is available upon request.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares), but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.

Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
Invesco Tax-Free Cash Reserve Portfolio
■ 
You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents
To reduce Fund expenses, only one copy of most shareholder documents may be mailed to shareholders with multiple accounts at the same address (Householding). Mailing of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your
household, please contact the Funds’ transfer agent at 800-659-1005 or contact your financial institution. The Funds’ transfer agent will begin sending you individual copies for each account within thirty days after receiving your request.

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities.
The Fund invests in conformity with U.S. Securities 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 60 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 60 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other
factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
4        Short-Term Investment Trust

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days.

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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to

repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.

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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as
8        Short-Term Investment Trust

real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.
The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board of Trustees, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits
13        Short-Term Investment Trust

from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
18        Short-Term Investment Trust

Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax
developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Government & Agency Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested, under normal circumstances, 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, as well as repurchase agreements secured by those obligations. Direct obligations of the U.S. Treasury generally include bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions.

The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time.

The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

The Fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio , after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.02% of Invesco Treasury Obligations Portfolio's average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco Tax-Free Cash Reserve Portfolio , after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares), but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
A-5        The Invesco Funds

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
Invesco Tax-Free Cash Reserve Portfolio
■ 
You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents
To reduce Fund expenses, only one copy of most shareholder documents may be mailed to shareholders with multiple accounts at the same address (Householding). Mailing of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your
household, please contact the Funds’ transfer agent at 800-659-1005 or contact your financial institution. The Funds’ transfer agent will begin sending you individual copies for each account within thirty days after receiving your request.

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities.
The Fund invests in conformity with U.S. Securities 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 60 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 60 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to
6        Short-Term Investment Trust

repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7, under the Investment Company Act of 1940, as amended (Rule 2a-7) 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time.

The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.

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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits
13        Short-Term Investment Trust

from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general
16        Short-Term Investment Trust

outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence,
17        Short-Term Investment Trust

increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well,
21        Short-Term Investment Trust

there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
22        Short-Term Investment Trust

Risks
The principal risks of investing in the Fund are:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio , after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.

During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco Tax-Free Cash Reserve Portfolio , after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

For Invesco Treasury Portfolio and Invesco Government & Agency Portfolio, the Funds’ transfer agent will normally wire payment for redemptions received prior to 5:30 p.m. Eastern Time on the business day received, and in any event no more than seven days, after your redemption request is received in good order. However, depending on such factors as market liquidity and the size of the redemption, for a redemption request received by the Funds’ transfer agent between 5:00 p.m. Eastern Time and 5:30 p.m. Eastern Time, proceeds may not be wired until the next business day. If the Funds’ transfer agent receives a redemption request on a business day after 5:30 p.m. Eastern Time, the redemption will be effected at the net asset value of each Fund determined on the next business day, and the Funds’ transfer agent will normally wire redemption proceeds on such next business day, and in any event no more than seven days, after your redemption request is received in good order.
If a Fund exercises its discretion to close early on a business day, as described in the “Pricing of Shares—Timing of Orders” section of this prospectus, the Fund may not provide same day settlement of redemption orders.
Dividends payable up to the date of redemption on redeemed shares will normally be paid or reinvested on the next dividend payment date. However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
For Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, the Funds’ transfer agent will normally wire payment for redemptions received prior to 3:00 p.m. Eastern Time on the business day received, and in any event no more than seven days, after your redemption request is received in good order. However, depending on such factors as market liquidity and the size of the redemption, proceeds may not be wired until the next business day. If the Funds’ transfer agent receives a redemption request on a

However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares), but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
A-5        The Invesco Funds

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
Invesco Tax-Free Cash Reserve Portfolio
■ 
You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Reserve Class shares to 1.05%, of the Fund's average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2022.

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security.

Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to
6        Short-Term Investment Trust

repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect.

The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns
10        Short-Term Investment Trust

over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.

The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits
13        Short-Term Investment Trust

from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco STIC Prime Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 60 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 60 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers
factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general
16        Short-Term Investment Trust

outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence,
17        Short-Term Investment Trust

increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.

If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Invesco Government & Agency Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund as defined by Rule 2a-7.

Direct obligations of the U.S. Treasury generally include bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities.

For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency
rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Invesco Treasury Obligations Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.
The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. In addition, 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, which include Treasury bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Risks
The principal risks of investing in the Fund are:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio , after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.

The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Other Information
Dividends and Distributions
Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio expect, based on their investment objective and strategies, that their dividends and distributions, if any, will consist primarily of ordinary income.
Invesco Tax-Free Cash Reserve Portfolio expects, based on its investment objective and strategies, that its dividends and distributions, if any, will consist primarily of tax-exempt income.
Dividends
Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio generally declare dividends, if any, daily and pay them monthly.
Dividends are paid on settled shares of the Invesco Treasury Portfolio and Invesco Government & Agency Portfolio as of 5:30 p.m. Eastern Time, Invesco Tax-Free Cash Reserve Portfolio as of 4:00 p.m. Eastern Time and Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio and Invesco Treasury Obligations Portfolio as of 3:00 p.m. Eastern Time (“Settlement Time”). If a Fund closes early on a business day, such Fund will pay dividends on settled shares at such earlier closing time. Generally, shareholders whose purchase orders have been accepted by the Funds prior to the respective Fund’s Settlement Time, or an earlier close time on any day that a Fund closes early, are eligible to receive dividends on that business day. The dividend declared on any day preceding a non-business day or days of a Fund will include the net income accrued on such non-business day or days. Dividends and distributions are reinvested in the form of additional full and fractional shares at net asset value unless the shareholder has elected to have such dividends and distributions paid in cash. See “Pricing of Shares -Timing of Orders” for a description of the Fund’s business days.
Capital Gains Distributions
Each Fund generally distributes net realized capital gains (including net short-term capital gains), if any, at least annually. Each Fund does not expect to realize any long-term capital gains and losses.

Financial Highlights
The financial highlights table is intended to help you understand each Fund’s financial performance for the past five years of the Reserve Class shares. Certain information reflects financial results for a single Fund share.
The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions).
This information has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with a Fund’s financial statements, is included in each Fund’s annual report, which is available upon request.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares), but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
Invesco Tax-Free Cash Reserve Portfolio
■ 
You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents

Principal Investment Strategies of the Fund
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by
nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund’s Board of Trustees (the Board), and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial
1        Short-Term Investment Trust

support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. 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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (“LIBOR”) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these instruments, which could result in a loss.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly
2        Short-Term Investment Trust

and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Resource Class shares to 0.34%, of the Fund's average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2022. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.
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.

Principal Investment Strategies of the Fund
The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. Government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.
The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities.
The Fund invests in conformity with U.S. Securities 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 60 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 60 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other
factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly), the supply of short-term financing, changes in government regulation, changes in interest rates, and economic downturns in the United States and abroad.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.
4        Short-Term Investment Trust

Repurchase Agreement Risk. The Fund is subject to the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S.
Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund invests in conformity with U.S. Securities 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 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.

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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates.

repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value.

The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as
8        Short-Term Investment Trust

real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Principal Investment Strategies of the Fund
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.
The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states.
The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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 at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities.
The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board of Trustees, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 government 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:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.

Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole.

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 debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 (which include tender option bonds and variable rate instruments which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. The Fund invests in conformity with U.S. Securities 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure. The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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 government 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:
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. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters,
12        Short-Term Investment Trust

widespread disease or other public health issues, war, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
Foreign Securities and 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. Furthermore, the Fund's foreign investments may be adversely affected by political and social instability, changes in economic or taxation policies, difficulty in enforcing obligations, decreased liquidity or increased volatility. Foreign investments also involve the risk of the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investments in a certain market) and the possible adoption of foreign governmental restrictions such as exchange controls.
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 these instruments, which could result in a loss.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Investment Objective(s), Strategies, Risks and Portfolio Holdings
Invesco Liquid Assets Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests primarily in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) securities issued by the U S Government or its agencies; (ii) certificates of deposit and time deposits
13        Short-Term Investment Trust

from U S or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal 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 fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
The Fund is a money market fund that rounds the Fund’s current NAV per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
The Fund may invest up to 50% of its total assets in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.
For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.
Risks
The principal risks of investing in the Fund are:
Money Market Fund Risk. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them and you may lose money by investing in the Fund.The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors.The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time. 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, illiquid markets, and/or significant market volatility.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing
14        Short-Term Investment Trust

political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Restricted Securities Risk. Limitations on the resale of restricted securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility. In addition, the Fund may get only limited information about the issuer of a restricted security and therefore may be less able to predict a loss.
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. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Banking and Financial Services Industry Focus Risk. From time to time, the Fund may invest more than 25% of its assets in unsecured bank instruments, including but not limited to certificates of deposit and time deposits, or securities that may have guarantees or credit or liquidity enhancements provided by banks, insurance companies or other financial institutions. To the extent the Fund focuses its investments in these instruments or securities, the Fund’s performance will depend on the overall condition of those industries and the individual banks and financial institutions in which the Fund invests (directly or indirectly). Financial services companies may be dependent on the supply of short-term financing. The value of bank instruments and securities of issuers in the banking and financial services industry, or guaranteed by such issuers, can be affected by and sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. The risk of holding bank instruments is also directly tied to the risk of insolvency or bankruptcy of the issuing banks, which risk may be higher for larger or more complex financial institutions that combine traditional, commercial and investment banking.
LIBOR Transition Risk. The Fund invests in financial instruments that utilize the London Interbank Offered Rate (LIBOR) as the reference or benchmark rate for variable interest rate calculations. On July 27, 2017, the
head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on the Fund or the instruments in which the Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate (e.g., the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. dollar LIBOR) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to the Fund.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
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 these 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.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal
15        Short-Term Investment Trust

government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Invesco Treasury Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. Government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, 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 including bills, notes and bonds, and repurchase agreements secured by those obligations. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash.
Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.

Risks
The principal risks of investing in the Fund are:
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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility. While the Board of Trustees may implement procedures to impose a fee upon the sale of your shares or temporarily suspend your ability to sell shares in the future if the Fund’s liquidity falls below required minimums because of market conditions or other factors, the Board has not elected to do so at this time. Should the Board elect to do so, such change would only become effective after shareholders were provided with specific advance notice of the change in the Fund’s policy and provided with the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.
18        Short-Term Investment Trust

Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally. The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax
developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Invesco Government & Agency Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund primarily invests in U.S. Treasury Obligations and Government Securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements collateralized fully by U.S. Treasury Obligations and Government Securities. The Fund may also hold cash.
The Fund is a Government Money Market Fund as defined by Rule 2a-7. As permitted by Rule 2a-7, the Fund 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 at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. In addition, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested, under normal circumstances, 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, as well as repurchase agreements secured by those obligations. Direct obligations of the U.S. Treasury generally include bills, notes and bonds. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy does not include cash or repurchase agreements collateralized by cash. Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government securities for purposes of the Fund’s investment policies.
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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions.

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. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time. 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, illiquid markets, and/or significant market volatility.

U.S. Government Obligations Risk. Obligations of U.S. Government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. Government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Invesco Tax-Free Cash Reserve Portfolio
Objective(s) and Strategies
The Fund’s investment objective is to provide tax-exempt income consistent with preservation of capital and liquidity. The Fund’s investment objective may be changed by the Board without shareholder approval.
The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that (i) pay interest that is excluded from gross income for federal income tax purposes, and (ii) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. While the Fund’s distributions are primarily exempt from federal income tax, a portion of the Fund’s distributions may be subject to the federal alternative minimum tax and state and local taxes.
In complying with the 80% investment requirement, the Fund may include other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.
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 tender option bonds and variable rate instruments, which are created when fixed rate bonds are coupled with a third-party demand feature) and certain types of industrial revenue bonds 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 intends to qualify as a Retail Money Market Fund, as defined by Rule 2a-7, 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. Retail Money Market Funds may be beneficially owned only by natural persons, as determined in the “Shareholder Account Information – Purchasing Shares” section of this Prospectus. 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 calendar 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 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days. Each investment must be determined to present minimal credit risks by the Adviser pursuant to guidelines approved by the Board, and must be an Eligible Security as defined by Rule 2a-7. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.
The Fund may also invest in daily and weekly variable-rate demand notes.
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 Adviser’s credit research process considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations.
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.
The Fund may, from time to time, take temporary defensive positions by holding cash, shortening the Fund’s dollar-weighted average portfolio maturity or investing in other securities that are Eligible Securities for purchase by money market funds as described in the Fund’s Statement of Additional Information (SAI), in anticipation of or in response to adverse market, economic, political or other conditions. If the Fund’s portfolio managers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.
The Fund’s investments in the types of securities and other investments described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities and other investments described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. If an issuer seeks to restructure the terms of its borrowings or the Fund is required to seek recovery upon a default in the payment of interest or the repayment of principal, the Fund may incur additional expenses. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.
Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. 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 the security. Municipal obligations may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. Municipal securities structured as revenue bonds are generally not backed by the taxing power of the issuing municipality but rather the revenue from the particular project or entity for which the bonds were issued. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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.
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, or adverse investor sentiment generally.
The value of the Fund’s investments may also go up or down due to factors that affect an individual issuer or a particular industry or sector, such as changes in production costs and competitive conditions within an industry. In addition, natural or environmental disasters, widespread disease or other public health issues, war, acts of terrorism or other events may have a significant impact on the value of the Fund’s investments, as well as the financial markets and global economy generally. Such circumstances may also impact the ability of the Adviser to effectively implement the Fund’s investment strategy. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.
■ 
COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, and defaults, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on the Fund’s performance.
Foreign Securities and 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. Furthermore, the value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.
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 these 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.
Yield Risk. 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. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.
Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations assessed as part of a credit research process may vary, and not every ESG factor may be identified or evaluated for every investment. Information used to evaluate such factors may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact the ability to accurately assess credit quality, which could negatively impact the Fund’s performance. There is no guarantee that the incorporation of ESG considerations will be additive to the Fund’s performance.
Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad, changes to the monetary policy by the Federal Reserve or other regulatory actions, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan or other legislation aimed at
23        Short-Term Investment Trust

addressing financial or economic conditions, the threat of a federal government shutdown, and threats not to increase or suspend the federal government’s debt limit, may affect investor and consumer confidence, increase volatility in the financial markets, perhaps suddenly and to a significant degree, result in higher interest rates, and even raise concerns about the U.S. government’s credit rating and ability to service its debt. Such changes and events may adversely impact the Fund’s operations, universe of potential investment options, and return potential.
Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.
Portfolio Holdings
Information concerning the Funds' portfolio holdings as well as their dollar-weighted average portfolio maturity and dollar-weighted average life to maturity as of the last business day or subsequent calendar day of the preceding month will be posted on their website no later than five business days after the end of the month and remain posted on the website for six months thereafter.
A description of Fund policies and procedures with respect to the disclosure of Fund portfolio holdings is available in the SAI, which is available at www.invesco.com/us.

Fund Management
The Adviser(s)
Invesco serves as each Fund’s investment adviser. The Adviser manages the investment operations of each Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of each Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.
Sub-Advisers. Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Funds (the Sub-Advisers). Invesco may appoint the Sub-Advisers from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.
Adviser Compensation
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.11% of Invesco Liquid Assets Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco STIC Prime Portfolio , after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.04% of Invesco Treasury Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.01% of Invesco Government & Agency Portfolio’s average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser received compensation of 0.02% of Invesco Treasury Obligations Portfolio's average daily net assets, after fee waiver and/or expense reimbursement, if any.
During the fiscal year ended August 31, 2021, the Adviser did not receive any compensation from Invesco Tax-Free Cash Reserve Portfolio , after fee waiver and/or expense reimbursement, if any.
The Adviser, Invesco Distributors, or one of their affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries for marketing support and/or administrative support. These marketing support payments and administrative support payments are in addition to the payments by the Funds described in this prospectus. Because they are not paid by the Funds, these marketing support payments and administrative support payments will not change the price paid by investors for the purchase of the Funds’ shares or the amount that a Fund will receive as proceeds from such sales. In certain cases these cash payments could be significant to the financial intermediaries. These cash payments may also create an incentive for a financial intermediary to recommend or sell shares of the Funds to its customers. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of shares of the Funds or the provision of services to the Funds. Also, please see the Funds’ SAI for more information about these types of payments.
A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of each Fund is available in each Fund’s most recent annual or semi-annual report to shareholders.

Hypothetical Investment and Expense Information
In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of each Fund’s expenses, including investment advisory
fees and other Fund costs, on each Fund’s returns over a 10-year period. The example reflects the following:
■ 
You invest $10,000 in the Fund and hold it for the entire 10-year period;
■ 
Your investment has a 5% return before expenses each year; and
■ 
Each Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed.
There is no assurance that the annual expense ratio will be the expense ratio for the Funds’ classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

However, if all of the shares in your account were redeemed from an individual account or from an aggregate account, you may request that the dividends payable up to the date of redemption accompany the proceeds of the redemption.
Redemptions by Telephone
If you redeem by telephone, the Funds’ transfer agent will transmit the amount of the redemption proceeds electronically to your pre-authorized bank account. The Funds’ transfer agent uses reasonable procedures to confirm that instructions communicated by telephone are genuine, and the
Funds and the Funds’ transfer agent are not liable for telephone instructions that are reasonably believed to be genuine.
Redemptions by Internet
If you redeem via our website, the Funds’ transfer agent will transmit your redemption proceeds electronically to your pre-authorized bank account. The Funds and the Funds’ transfer agent are not liable for internet instructions that are not genuine.
Suspension of Redemptions
In the event that a Fund, at the end of a business day, has invested less than 10% of its total assets in weekly liquid assets or the Fund’s price per share as computed for the purpose of distribution, redemption and repurchase, rounded to the nearest 1%, has deviated from the stable price established by the Fund’s Board of Trustees (“Board”) or the Board, including a majority of trustees who are not interested persons as defined in the 1940 Act, determines that such a deviation is likely to occur, and the Board, including a majority of trustees who are not interested persons of the Fund, irrevocably has approved the liquidation of the Fund, the Fund’s Board has the authority to suspend redemptions of Fund shares.
Liquidity Fees and Redemption Gates
For Invesco Tax-Free Cash Reserve Portfolio, Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, if the Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or suspend redemptions (redemption gates). In addition, if any such Fund’s weekly liquid assets falls below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund.
Liquidity fees and redemption gates are most likely to be imposed, if at all, during times of extraordinary market stress. In the event that a liquidity fee or redemption gate is imposed, the Board expects that for the duration of its implementation and the day after which such gate or fee is terminated, the Fund would strike only one net asset value per day, at the Fund’s last scheduled net asset value calculation time.
The imposition and termination of a liquidity fee or redemption gate will be reported by a Fund to the SEC on Form N-CR. Such information will also be available on the Fund’s website. In addition, a Fund will communicate such action through a supplement to its registration statement and may further communicate such action through a press release or by other means. If a liquidity fee is applied by the Board, it will be charged on all redemption orders submitted after the effective time of the imposition of the fee by the Board. Liquidity fees would reduce the amount you receive upon redemption of your shares. In the event a Fund imposes a redemption gate, the Fund or any financial intermediary on its behalf will not accept redemption requests until the Fund provides notice that the redemption gate has been terminated.
Redemption requests submitted while a redemption gate is imposed will be cancelled without further notice. If shareholders still wish to redeem their shares after a redemption gate has been lifted, they will need to submit a new redemption request.
Liquidity fees and redemption gates will generally be used to assist a Fund to help preserve its market–based NAV per share. It is possible that a liquidity fee will be returned to shareholders in the form of a distribution. The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of a Fund. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect. When a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
A-3        The Invesco Funds

There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject to future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Financial intermediaries are required to promptly take the steps requested by the Funds or their designees to impose or help to implement a liquidity fee or redemption gate as requested from time to time, including the rejection of orders due to the imposition of a fee or gate or the prompt re-confirmation of orders following a notification regarding the implementation of a fee or gate. If a liquidity fee is imposed, these steps are expected to include the submission of separate, rather than combined, purchase and redemption orders from the time of the effectiveness of the liquidity fee or redemption gate and the submission of such order information to the Fund or its designee prior to the next calculation of a Fund’s net asset value. Unless otherwise agreed to between a Fund and financial intermediary, the Fund will withhold liquidity fees on behalf of financial intermediaries. With regard to such orders, a redemption request that a Fund determines in its sole discretion has been received in good order by the Fund or its designated agent prior to the imposition of a liquidity fee or redemption gate may be paid by the Fund despite the imposition of a redemption gate or without the deduction of a liquidity fee. If a liquidity fee is imposed during the day, an intermediary who receives both purchase and redemption orders from a single account holder is not required to net the purchase and redemption orders. However, the intermediary is permitted to apply the liquidity fee to the net amount of redemptions (even if the purchase order was received prior to the time the liquidity fee was imposed).
Where a Financial Intermediary serves as a Fund’s agent for the purpose of receiving orders, trades that are not transmitted to the Fund by the Financial Intermediary before the time required by the Fund or the transfer agent may, in the Fund’s discretion, be processed on an as-of basis, and any cost or loss to the Fund or transfer agent or their affiliates, from such transactions shall be borne exclusively by the Financial Intermediary.
Redemptions by Large Shareholders
At times, the Fund may experience adverse effects when certain large shareholders redeem large amounts of shares of the Fund. Large redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so. In addition, these transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains and may also increase transaction costs and/or increase in the Fund’s expense ratio. When experiencing a redemption by a large shareholder, the Fund may delay payment of the redemption request up to seven days to provide the investment manager with time to determine if the Fund can redeem the request-in-kind or to consider other alternatives to lessen the harm to remaining shareholders. Under certain circumstances, however, the Fund may be unable to delay a redemption request, which could result in the automatic processing of a large redemption that is detrimental to the Fund and its remaining shareholders.
Redemptions Initiated by the Funds
If a Fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the Fund is not able to verify your identity as required by law, the Fund may, at its discretion, redeem the account and distribute the proceeds to you.
In order to separate retail investors (natural persons) and non-retail investors, Invesco Tax-Free Cash Reserve Portfolio reserves the right to redeem shares in any account that the Fund cannot confirm to its satisfaction are beneficially owned by natural persons. The Fund will provide advance written notice of its intent to make any such involuntary redemptions.
Neither a Fund nor its investment adviser will be responsible for any loss in an investor’s account or tax liability resulting from an involuntary redemption.
Rights Reserved by the Funds
Each Fund and its agent reserve the right at any time to:
■ 
reject or cancel all or any part of any purchase order;
■ 
modify any terms or conditions related to the purchase or redemption of shares of any Fund; or
■ 
suspend, change or withdraw all or any part of the offering made by this prospectus.
Exchanging Shares
You may only exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio or Invesco Treasury Portfolio for shares of other money market funds in Short-Term Investments Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares), but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Pricing of Shares
Determination of Net Asset Value
Invesco Treasury Portfolio and Invesco Government & Agency Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Each Fund will generally determine the net asset value of its shares at 5:30 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee that their net asset value will always remain at $1.00 per share.
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco STIC Prime Portfolio generally determines the net asset value of its shares at 3:00 p.m. Eastern Time, and Invesco Liquid Assets Portfolio generally determines the net asset value of its shares at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early on a business day, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close.
Each Fund values its portfolio securities for which market quotations are readily available at market value, and calculates its net asset values to four decimals (e.g., $1.0000). Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Funds value securities and assets for which market quotations are unavailable at their “fair value,” which is described below.
Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the New York Stock Exchange (NYSE) and when the Fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events that affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where the Adviser determines that the closing price of the security is stale or unreliable, the Adviser will value the security at its fair value.
Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. A fair value price is an estimated price that requires consideration of all appropriate factors, including indications of fair value available from pricing services. Fair value pricing involves judgment and a Fund that uses fair value methodologies
A-4        The Invesco Funds

may value securities higher or lower than another Fund using market quotations or its own fair value methodologies to price the same securities.
Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the Fund had not fair-valued the security or had used a different methodology.
The Board has delegated the daily determination of fair value prices to the Adviser’s valuation committee, which acts in accordance with Board approved policies. Fair value pricing methods and pricing services can change from time to time as approved by the Board.
The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of a Fund’s portfolio at the time that the NAV is calculated. An additional intended effect is to discourage those seeking to take advantage of arbitrage opportunities resulting from “stale” prices and to mitigate the dilutive impact of any such arbitrage. However, the application of fair value pricing cannot eliminate the possibility that arbitrage opportunities will exist.
Specific types of securities are valued as follows:
Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.
Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. The Adviser also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time. Fund securities primarily traded on foreign markets may trade on days that are not business days of the Fund. Because the net asset value of Fund shares is determined only on business days of the Fund, the value of the portfolio securities of a Fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the Fund.
Fixed Income Securities. Fixed income securities, such as government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Pricing services generally value fixed income securities assuming orderly transactions of institutional round lot size, but a Fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Adviser’s valuation committee will fair value the security using procedures approved by the Board.
Short-term Securities. The Funds value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.
Open-end Funds. If a Fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing Fund will calculate its net asset value using the net asset value of the underlying fund in which it invests, and the prospectuses for such open-end funds explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.
Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio
The price of each Fund’s shares is the Fund’s net asset value per share. Invesco Treasury Obligations Portfolio will generally determine the net asset value of its shares at 3:30 p.m. Eastern Time. Invesco Tax-Free Cash Reserve Portfolio will generally determine the net asset value of its shares at 4:00 p.m. Eastern Time.
If a Fund closes early on a business day, as described below under “Pricing of Shares—Timing of Orders”, the Fund will calculate its net asset value as of the time of such closing.
Each Fund values portfolio securities on the basis of amortized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share.
Timing of Orders
Each Fund opens for business at 7:30 a.m. Eastern Time. Each Fund prices purchase and redemption orders on each business day at the net asset value calculated after the Funds’ transfer agent receives an order in good form.
A business day is any day that (1) both the Federal Reserve Bank of New York and the Fund’s custodian are open for business and (2) the primary trading markets for the Fund’s portfolio instruments are open and the Fund’s management believes there is an adequate market to meet purchase and redemption requests. Each Fund is authorized not to open for trading on a day that is otherwise a business day if the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading; any such day will not be considered a business day. Each Fund also may close early on a business day if the SIFMA recommends that government securities dealers close early.
If the financial intermediary through which you place purchase and redemption orders, in turn, places its orders to the Funds’ transfer agent through the NSCC, the Funds’ transfer agent may not receive those orders until the next business day after the order has been entered into the NSCC.
Each Fund may postpone the right of redemption under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.
Thirty minutes prior to the Funds’ net asset value determination, Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio may, in their discretion, limit or refuse to accept purchase orders and may not provide same-day payment of redemption proceeds.
If a Fund closes early on a business day, as described in this section, the Fund will calculate its net asset value as of the time of such closing.
Currently, certain financial intermediaries may serve as agents for the Funds and accept orders on their behalf. Where a financial intermediary serves as agent, the order is priced at the Fund’s net asset value next calculated after it is accepted by the financial intermediary. In such cases, if requested by a Fund, the financial intermediary is responsible for providing information with regard to the time that such order for purchase, redemption or exchange was received. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
A-5        The Invesco Funds

Frequent Purchases and Redemptions of Fund Shares
The Board of the Funds has not adopted any policies and procedures that would limit frequent purchases and redemptions of the Funds’ shares. The Board does not believe that it is appropriate to adopt any such policies and procedures for the following reasons:
■ 
Each Fund is offered to investors as a cash management vehicle; therefore, investors should be able to purchase and redeem shares regularly and frequently.
■ 
One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of a Fund will be detrimental to the continuing operations of the Fund.
■ 
With respect to Funds maintaining a constant net asset value, each Fund’s portfolio securities are valued on the basis of amortized cost, and the Funds seek to maintain a constant net asset value. As a result, the Funds are not subject to price arbitrage opportunities.
■ 
With respect to Funds maintaining a constant net asset value, because such Funds seek to maintain a constant net asset value, investors are more likely to expect to receive the amount they originally invested in the Funds upon redemption than other mutual funds. Imposition of redemption fees would run contrary to investor expectations.
The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and it determined that those risks are minimal, especially in light of the reasons for not having such a policy as described above. Nonetheless, to the extent that each Fund must maintain additional cash and/or securities with shorter-term durations than may otherwise be required, the Fund’s yield could be negatively impacted. Moreover, excessive trading activity in the Fund’s shares may cause the Fund to incur increased brokerage and administrative costs.
Each Fund and its agent reserve the right at any time to reject or cancel any part of any purchase order. This could occur if each Fund determines that such purchase may disrupt the Fund’s operation or performance.
Taxes
A Fund intends to qualify each year as a regulated investment company and, as such, is not subject to entity-level tax on the income and gain it distributes to shareholders. If you are a taxable investor, dividends and distributions you receive from a Fund generally are taxable to you whether you reinvest distributions in additional Fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from a Fund during the prior calendar year. In addition, investors in taxable accounts should be aware of the following basic tax points as supplemented below where relevant:
Fund Tax Basics
■ 
A Fund earns income generally in the form of interest on its investments. This income, less expenses incurred in the operation of a Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable to you as ordinary income.
■ 
Distributions of net short-term capital gains are taxable to you as ordinary income. Because a Fund is a money market fund, it does not anticipate realizing any long-term capital gains.
■ 
None of the dividends paid by a Fund will qualify as qualified dividend income subject to reduced rates of taxation in the case of non-corporate shareholders.
■ 
Distributions declared to shareholders with a record date in December—if paid to you by the end of January—are taxable for federal income tax purposes as if received in December.
■ 
Any capital gains realized from redemptions of Fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another Fund is the same as a sale. An exchange occurs when the purchase of shares of a Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Because the Funds, other than the Invesco Liquid Assets Portfolio and the Invesco STIC Prime Portfolio, expect to maintain a stable net asset value of $1.00 per share, investors
should not have any gain or loss on sale or exchange of Fund shares (unless the investor incurs a liquidity fee on such sale or exchange). See, “Liquidity Fees and Redemption Gates.”
■ 
Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a minimum of the fourth decimal place, therefore, investors will have gain or loss on the sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
■ 
Regarding Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, because the Fund is not expected to maintain a stable share price, a sale or exchange of Fund shares may result in a capital gain or loss for you. Unless you choose to adopt a simplified “NAV method” of accounting (described below), any capital gain or loss on the sale or exchange of Fund shares (as noted above) generally will be treated either as short-term if you held your Fund shares for one year or less, or long-term if you held your Fund shares longer. If you elect to adopt the NAV method of accounting, rather than computing gain or loss on every taxable disposition of Fund shares as described above, you would determine your gain or loss based on the change in the aggregate value of your Fund shares during a computation period (such as your taxable year), reduced by your net investment (purchases minus sales) in those shares during that period. Under the NAV method, any resulting net capital gain or loss would be treated as short-term capital gain or loss.
■ 
By law, if you do not provide a Fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A Fund also must withhold if the Internal Revenue Service (IRS) instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid.
■ 
You will not be required to include the portion of dividends paid by a Fund derived from interest on U.S. government obligations in your gross income for purposes of personal and, in some cases, corporate income taxes in many state and local tax jurisdictions. The percentage of dividends that constitutes dividends derived from interest on federal obligations will be determined annually. This percentage may differ from the actual percentage of interest received by the Fund on federal obligations for the particular days on which you hold shares.
■ 
An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from a Fund and net gains from redemptions or other taxable dispositions of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return.
■ 
Fund distributions and gains from sale or exchange of your Fund shares generally are subject to state and local income taxes, except for Invesco Tax-Free Cash Reserve Portfolio. Information on Invesco Tax-Free Cash Reserve Portfolio is located below, under the heading “Invesco Tax-Free Cash Reserve Portfolio.”
■ 
Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits, and estate taxes may apply to an investment in a Fund.
■ 
Under the Foreign Account Tax Compliance Act (FATCA), a Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions or non-financial foreign entities, that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). A Fund may disclose the information that it receives from its shareholders to the IRS, non-U.S.
A-6        The Invesco Funds

taxing authorities or other parties as necessary to comply with FATCA or similar laws. Withholding also may be required if a foreign entity that is a shareholder of a Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.
■ 
There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
The above discussion concerning the taxability of Fund dividends and distributions and of redemptions and exchanges of Fund shares is inapplicable to investors that generally are exempt from federal income tax, such as retirement plans that are qualified under Section 401 and 403 of the Code and individual retirement accounts (IRAs) and Roth IRAs.
Invesco Tax-Free Cash Reserve Portfolio
■ 
You will not be required to include the “exempt-interest” portion of dividends paid by the Fund in either your gross income for federal income tax purposes or your net investment income subject to the additional 3.8% Medicare tax. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax returns. The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the Fund for the particular days in which you hold shares.
■ 
A Fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for noncorporate shareholders, unless such municipal securities were issued in 2009 or 2010.
■ 
Exempt-interest dividends from interest earned on municipal securities of a state, or its political subdivisions, generally are exempt from that state’s personal income tax. Most states, however, do not grant tax-free treatment to interest from municipal securities of other states.
■ 
A Fund may invest a portion of its assets in securities that pay income that is not tax-exempt. To the extent that dividends paid by a Fund are derived from taxable investments or realized capital gains, they will be taxable as ordinary income or long-term capital gains.
■ 
A Fund may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, Fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends-received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of noncorporate shareholders.
■ 
Exempt-interest dividends from a Fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.
■ 
There are risks that: (a) a security issued as tax-exempt may be reclassified by the IRS or a state tax authority as taxable and/or (b) future legislative, administrative or court actions could adversely impact the qualification of income from a tax-exempt security as tax-free. Such reclassifications or actions could cause interest from a security to become taxable, possibly retroactively, subjecting you to increased tax liability. In addition, such reclassifications or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.
This discussion of “Taxes” is for general information only and not tax advice. All investors should consult their own tax advisers as to the federal, state, local and foreign tax provisions applicable to them.
Important Notice Regarding Delivery of Security Holder Documents
To reduce Fund expenses, only one copy of most shareholder documents may be mailed to shareholders with multiple accounts at the same address (Householding). Mailing of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your
household, please contact the Funds’ transfer agent at 800-659-1005 or contact your financial institution. The Funds’ transfer agent will begin sending you individual copies for each account within thirty days after receiving your request.

GENERAL INFORMATION ABOUT THE TRUST
Fund History
Short-Term Investments Trust (the Trust) is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end series management investment company. The Trust was originally organized on January 24, 1977 as a Maryland corporation and had no operations prior to November 10, 1980. The Trust re-organized as a Commonwealth of Massachusetts business trust on December 31, 1986. The Trust was again reorganized as a business trust under the laws of the State of Delaware on October 15, 1993. Under the Trust’s Agreement and Declaration of Trust, as amended, (the Trust Agreement), the Board of Trustees of the Trust (the Board) is authorized to create new series of shares without the necessity of a vote of shareholders of the Trust.
Prior to April 30, 2008, Tax-Free Cash-Reserve Portfolio succeeded to the assets and assumed the liabilities of Tax-Free Cash Reserve Portfolio, (the “Predecessor Fund”) of Tax-Free Investments Trust, a Delaware statutory trust (TFIT).
Prior to November 4, 2016, Treasury Obligations Portfolio was known as Government TaxAdvantage Portfolio.
Prior to December 15, 2017, Invesco Liquid Assets Portfolio was known as Liquid Assets Portfolio, Invesco STIC Prime Portfolio was known as STIC Prime Portfolio, Invesco Treasury Portfolio was known as Treasury Portfolio, Invesco Government & Agency Portfolio was known as Government & Agency Portfolio, Invesco Treasury Obligations Portfolio was known as Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio was known as Tax-Free Cash Reserve Portfolio.
Shares of Beneficial Interest
Shares of beneficial interest of the Trust are redeemable at their net asset value at the option of the shareholder or at the option of the Trust, in accordance with any applicable provisions of the Trust Agreement and applicable law, subject in certain circumstances to a contingent deferred sales charge, if applicable.
The Trust allocates cash and property it receives from the issue or sale of shares, together with all assets in which such consideration is invested or reinvested, all income, earnings, profits and proceeds thereof, to the appropriate Fund, subject only to the rights of creditors of that Fund. These assets constitute the assets belonging to each Fund, are segregated on the Trust’s books, and are charged with the liabilities and expenses of such Fund and its respective classes. The Trust allocates any general liabilities and expenses of the Trust not readily identifiable as belonging to a particular Fund primarily on the basis of relative net assets or other relevant factors, subject to oversight by the Board.
Each share of each Fund represents an equal pro rata interest in that Fund with each other share and is entitled to dividends and other distributions with respect to the Fund, which may be from income, capital gains or capital, as declared by the Board.
Each class of shares of a Fund represents a proportionate undivided interest in the net assets belonging to that Fund.  Differing sales charges and expenses will result in differing net asset values and dividends and distributions.  Upon any liquidation of the Trust, shareholders of each class are entitled to share pro rata in the net assets belonging to the applicable Fund allocable to such class available for distribution after satisfaction of, or reasonable provision for, the outstanding liabilities of the Fund allocable to such class.
The Trust Agreement provides that each shareholder, by virtue of having become a shareholder of the Trust, is bound by terms of the Trust Agreement and the Trust’s Bylaws. Ownership of shares does not make shareholders third party beneficiaries of any contract entered into by the Trust.
The Trust is not required to hold annual or regular meetings of shareholders. Meetings of shareholders of a Fund or class will be held for any purpose determined by the Board, including from time to time to consider matters requiring a vote of such shareholders in accordance with the requirements of the 1940 Act, state law or the provisions of the Trust Agreement. It is not expected that shareholder meetings will be held annually.
1

The Trust Agreement provides that the Board may authorize (i) a merger, consolidation or sale of assets (including, but not limited to, mergers, consolidations or sales of assets between two Funds, or between a Fund and a series of any other registered investment company), and (ii) the combination of two or more classes of shares of a Fund into a single class, each without shareholder approval but subject to applicable requirements under the 1940 Act and state law.
Each share of a Fund generally has the same voting, dividend, liquidation and other rights; however, each class of shares of a Fund is subject to different sales loads, conversion features, exchange privileges and class-specific expenses, as applicable.  Only shareholders of a specific class may vote on matters relating to that class’s distribution plan.
Except as specifically noted above, shareholders of each Fund are entitled to one vote per share (with proportionate voting for fractional shares), irrespective of the relative net asset value of the shares of the Fund. However, on matters affecting an individual Fund or class of shares, a separate vote of shareholders of that Fund or class is required. Shareholders of a Fund or class are not entitled to vote on any matter which does not affect that Fund or class but that requires a separate vote of another Fund or class. An example of a matter that would be voted on separately by shareholders of each Fund is the approval of the advisory agreement with Invesco Advisers, Inc. (the Adviser or Invesco).
When issued, shares of each Fund are fully paid and nonassessable, have no preemptive or subscription rights, and are freely transferable. Shares do not have cumulative voting rights in connection with the election of Trustees or on any other matter.
Under Delaware law, shareholders of a Delaware statutory trust shall be entitled to the same limitation of personal liability extended to shareholders of private for-profit corporations organized under Delaware law. There is a remote possibility, however, that shareholders could, under certain circumstances, be held liable for the obligations of the Trust to the extent the courts of another state, which does not recognize such limited liability, were to apply the laws of such state to a controversy involving such obligations. The Trust Agreement disclaims shareholder personal liability for the debts, liabilities, obligations and expenses of the Trust and requires that every undertaking of the Trust or the Board relating to the Trust or any Fund include a recitation limiting such obligation to the Trust and its assets or to one or more of the Funds and the assets belonging thereto. The Trust Agreement provides for indemnification out of the property of a Fund (or Class, as applicable) for all losses and expenses of any shareholder of such Fund held personally liable solely on account of being or having been a shareholder.
The trustees and officers of the Trust will not be liable for any act, omission or obligation of the Trust or any trustee or officer; however, a trustee or officer is not protected against any liability to the Trust or to the shareholders to which a trustee or officer would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office with the Trust or applicable Fund (Disabling Conduct). The Trust’s Bylaws generally provide for indemnification by the Trust of the trustees, officers and employees or agents of the Trust, provided that such persons have not engaged in Disabling Conduct. Indemnification does not extend to judgments or amounts paid in settlement in any actions by or in the right of the Trust. The Trust Agreement also authorizes the purchase of liability insurance on behalf of trustees and officers with Fund assets. The Trust’s Bylaws provide for the advancement of payments of expenses to current and former trustees, officers and employees or agents of the Trust, or anyone serving at their request, in connection with the preparation and presentation of a defense to any claim, action, suit or proceeding, for which such person would be entitled to indemnification; provided that any advancement of expenses would be reimbursed unless it is ultimately determined that such person is entitled to indemnification for such expenses.
The Trust Agreement provides that any Trustee who serves as chair of the Board or of a committee of the Board, lead independent Trustee, or an expert on any topic or in any area (including an audit committee financial expert), or in any other special appointment will not be subject to any greater standard of care or liability because of such position.

The Trust Agreement provides a detailed process for the bringing of derivative actions by shareholders. A shareholder may only bring a derivative action on behalf of the Trust if certain conditions are met. Among other things, such conditions: (i) require shareholder(s) to make a pre-suit demand on the Trustees (unless such effort is not likely to succeed because a majority of the Board or the committee established to consider the merits of such action are not independent Trustees under Delaware law); (ii) require 10% of the beneficial owners to join in the pre-suit demand; and (iii) afford the Trustees a reasonable amount of time to consider the request and investigate the basis of the claims (including designating a committee to consider the demand and hiring counsel or other advisers). These conditions generally are intended to provide the Trustees with the ability to pursue a claim if they believe doing so would be in the best interests of the Trust and its shareholders and to preclude the pursuit of claims that the Trustees determine to be without merit or otherwise not in the Trust’s best interest to pursue.
The Trust Agreement also generally requires that actions by shareholders in connection with or against the Trust or a Fund be brought only in certain Delaware courts and that the right to jury trial be waived to the fullest extent permitted by law.
Share Certificates
Shareholders of the Funds do not have the right to demand or require the Trust to issue share certificates and share certificates are not issued. Any certificate previously issued with respect to any shares is deemed to be cancelled without any requirement for surrender to the Trust.
DESCRIPTION OF THE FUNDS AND THEIR INVESTMENTS AND RISKS
Classification
The Trust is an open-end management investment company. Each of the Funds is classified as "diversified" for purposes of the 1940 Act and managed in accordance with Rule 2a-7 under the 1940 Act.
Investment Strategies and Risks
Set forth below are detailed descriptions of the various types of securities and investment techniques that Invesco and/or the Sub-Advisers (as defined herein) may use in managing the Funds, as well as the risks associated with those types of securities and investment techniques. The descriptions of the types of securities and investment techniques below supplement the discussion of principal investment strategies and risks contained in each Fund's Prospectuses. If a particular type of security or investment technique is not discussed in a Fund’s Prospectuses, that security or investment technique it is not a principal investment strategy of that Fund.
A Fund may invest in all of the following types of investments (unless otherwise indicated).  A Fund might not invest in all of these types of securities or use all of the techniques at any one time.  Invesco and/or the Sub-Advisers may invest in other types of securities and may use other investment techniques in managing the Funds as well as securities and techniques not described.  The Fund's transactions in a particular type of security or use of a particular technique is subject to limitations imposed by the Funds’ investment objective, policies and restrictions described in the Funds’ Prospectuses and/or this SAI, as well as the federal securities laws.
Any percentage limitations relating to the composition of a Fund’s portfolio identified in a Fund’s Prospectus or this SAI apply at the time the Fund acquires an investment. Subsequent changes that result from market fluctuations generally will not require a Fund to sell any portfolio security. However, a Fund may sell its illiquid investments holdings, or reduce its borrowings, if any, in response to fluctuations in the value of such holdings.
Generally, Invesco Tax-Free Cash Reserve Portfolio will invest only in tax-free securities.  Invesco Tax-Free Cash Reserve Portfolio may, however, invest in taxable short-term investments (Taxable Investments) consisting of obligations of the U.S. Government, its agencies or instrumentalities, banks and corporations, short-term fixed income securities; high quality commercial paper; certificates of deposit of domestic banks;
3

and U.S. dollar denominated foreign securities. The Fund may invest in Taxable Investments, for example, due to market conditions or pending the investment of proceeds from the sale of its shares or proceeds from the sale of portfolio securities or in anticipation of redemptions.  Although interest earned from Taxable Investments will be taxable to shareholders as ordinary income, the Fund generally intends to minimize taxable income through investments, when possible, in short-term tax-exempt securities, which may include shares of other investment companies whose dividends are tax-exempt.  See also “Dividends, Distributions and Tax Matters.”
The Funds' investment objectives, policies, strategies and practices described below are non-fundamental and may be changed without approval of the holders of the Funds’ voting securities, unless otherwise indicated.
Rule 2a-7 Requirements.
As permitted by Rule 2a-7 under the 1940 Act, each Fund 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. Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio “float” the net asset value of the Fund’s shares by valuing assets at market value and rounding the Fund’s current net asset value per share to a minimum of the fourth decimal place. Rule 2a-7 imposes requirements as to the diversification and liquidity of each Fund, quality of portfolio securities, maturity of the Funds and of individual securities. The discussion of investments in this SAI is qualified by Rule 2a-7 limitations.
As a “Government Money Market Fund” under Rule 2a-7, each of Invesco Treasury Portfolio, Invesco Government & Agency Portfolio and Invesco Treasury Obligations Portfolio (1) is permitted to use the amortized cost method of valuation to seek to maintain a $1.00 share price, (2) must invest at least 99.5% of its total assets in cash, government securities and/or, with respect to Invesco Treasury Portfolio and Invesco Government & Agency Portfolio, repurchase agreements that are “collateralized fully” (i.e., backed by cash or government securities) and (3) is not subject to a liquidity fee and/or a redemption gate on fund redemptions which might apply to other types of funds in the future should certain triggering events specified in Rule 2a-7 occur. (In conformance with Rule 2a-7, the Board has reserved its ability to change this policy with respect to liquidity fees and/or redemption gates, but such change would only become effective after shareholders were provided with specific advance notice of a change in the Fund’s policy and have the opportunity to redeem their shares in accordance with Rule 2a-7 before the policy change became effective.) Invesco Tax-Free Cash Reserve Portfolio intends to qualify as a “Retail Money Market Fund,” as defined by Rule 2a-7. As a Retail Money Market Fund, Invesco Tax-Free Cash Reserve Portfolio (1) is permitted to use the amortized cost method of valuation to seek to maintain a $1.00 share price, (2) may be subject to a liquidity fee and/or a redemption gate on fund redemptions should certain triggering events specified in Rule 2a-7 occur; and (3) is limited to investments by natural persons. For more information on shareholder eligibility, please see the Fund’s prospectus. Institutional money market funds (that are not Government Money Market Funds) may also be subject to a liquidity fee and/or a redemption gate on fund redemptions should certain triggering events specified in Rule 2a-7 occur. For more information on liquidity fees and redemptions, see “Purchase, Redemption, and Exchange of Shares” below.
Diversification. In summary, Rule 2a-7 requires that a money market fund may not invest in the securities of any issuer if, as a result, more than 5% of the Fund’s total assets would be invested in that issuer; provided that, each Fund may invest up to 25% of its total assets in securities of a single issuer for up to three business days after acquisition. Certain securities are not subject to this diversification requirement. These include: Government Securities; certain repurchase agreements; and shares of certain money market funds. Rule 2a-7 imposes a separate diversification test upon the acquisition of a guarantee or demand feature. (A demand feature is, in summary, a right to sell a security at a price equal to its approximate amortized cost plus accrued interest). Government Security generally means any security issued or guaranteed as to principal or interest by the U.S. Government or certain of its agencies or instrumentalities; or any certificate of deposit for any of the foregoing.
4

For purposes of these diversification requirements with respect to issuers of Municipal Securities (defined under the caption Municipal Securities), each state (including the District of Columbia and Puerto Rico), territory and possession of the United States (U.S.), each political subdivision, agency, instrumentality, and authority thereof, and each multi-state agency of which a state is a member is a separate “issuer.” When the assets and revenues of an agency, authority, instrumentality, or other political subdivision are separate from the government creating the subdivision and the security is backed only by assets and revenues of the subdivision, such subdivision would be deemed to be the sole issuer. Similarly, in the case of an industrial development bond or private activity bond, if such bond is backed only by the assets and revenues of the non-governmental user, then such non-governmental user would be deemed to be the sole issuer.
Quality. The Funds may invest only in U.S. dollar denominated securities that are “Eligible Securities” as defined in Rule 2a-7.  Rule 2a-7 defines an Eligible Security, in summary, as a security with a remaining maturity of 397 calendar days or less that the Funds’ investment adviser (subject to oversight and pursuant to guidelines established by the Board) determines present minimal credit risk to the Fund. The eligibility of a security with a guarantee may be determined based on whether the guarantee is an Eligible Security.
The Funds will limit investments to those which are Eligible Securities at the time of acquisition.
Liquidity. Under Rule 2a-7, a Fund must hold securities that are sufficiently liquid to meet reasonably foreseeable shareholder redemptions in light of the Funds’ obligations under section 22(e) of the 1940 Act (which forbids the suspension of the right of redemption, or postponement of the date of payment or satisfaction upon redemption for more than seven days after the tender of such security for redemption, subject to specified exemptions) and any commitments the Funds have made to shareholders. In addition, a Fund may not acquire an illiquid security if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in illiquid securities. A Fund (other than Invesco Tax-Free Cash Reserve Portfolio) also may not acquire any security other than a Daily Liquid Asset (cash, Government Securities, other securities that will mature or are subject to a demand feature that is exercisable and payable within one business day and amounts receivable and unconditionally due within one business day on pending sales of portfolio securities) if, immediately after the acquisition the Fund would have invested less than 10% of its total assets in Daily Liquid Assets.  A Fund may not acquire any security other than a Weekly Liquid Asset (cash, direct obligations of the U.S. Government, Government Securities issued by a person controlled or supervised by and acting as an instrumentality of the U.S. Government pursuant to authority granted by the Congress that are issued at a discount to the principal amount to be repaid at maturity and have a remaining maturity of 60 calendar days or less, securities that will mature or are subject to a demand feature that is exercisable and payable within 5 business days and amounts receivable and unconditionally due within 5 business days on pending sales of portfolio securities) if, immediately after the acquisition, the Fund would have invested less than 30% of its total assets in Weekly Liquid Assets.
Maturity. Under Rule 2a-7, each Fund invests only in U.S. dollar-denominated securities maturing within 397 calendar days (60 calendar days for Invesco STIC Prime Portfolio) of the date of purchase, with certain exceptions permitted by applicable regulations.   Each Fund maintains a dollar-weighted average portfolio maturity of no more than 60 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 of no more than 120 calendar days (60 calendar days for Invesco STIC Prime Portfolio). The maturity of a security is determined in compliance with Rule 2a-7, which for purposes of the dollar-weighted average portfolio maturity permits, among other things, certain securities bearing adjustable interest rates to be deemed to have a maturity shorter than their stated maturity.
Foreign Investments
Foreign Government Obligations. Debt securities issued by foreign governments are often, but not always, supported by the full faith and credit of the foreign governments, or their subdivisions, agencies or instrumentalities, that issue them. These securities involve the risks discussed below under “Foreign Debt Securities”. Additionally, the issuer of the debt or the governmental authorities that control repayment of the debt may be unwilling or unable to pay interest or repay principal when due. Political or economic changes or
5

the balance of trade may affect a country’s willingness or ability to service its debt obligations. Periods of economic uncertainty may result in the volatility of market prices of sovereign debt obligations, especially debt obligations issued by the governments of developing countries. Foreign government obligations of developing countries, and some structures of emerging market debt securities, both of which are generally below investment grade, are sometimes referred to as “Brady Bonds.” The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance, or repay principal or interest when due may result in the cancellation of third-party commitments to lend funds to the sovereign debtor, which may impair the debtor’s ability or willingness to service its debts.
Foreign Debt Securities. Foreign debt securities are debt securities that are issued and/or settled outside the United States and may be backed by foreign guarantees. A Fund will limit its investments in foreign debt securities to debt obligations denominated in U.S. dollars. Debt securities issued by a corporation or other issuer domiciled outside the United States that are dollar denominated and traded in the United States are not considered foreign securities. Although denominated in U.S. dollars, Foreign Debt Securities may entail some or all of the risks set forth below.
Political and Economic Risk. The economies of many countries may not be as developed as that of the United States’ economy and may be subject to significantly different forces. Political, economic or social instability and development, expropriation or confiscatory taxation, and limitations on the removal of funds or other assets could also adversely affect the value of portfolio investments. Certain foreign companies may be subject to sanctions, embargoes, or other governmental actions that may impair or otherwise limit the ability to invest in, receive, hold or sell the securities of such companies. These factors may affect the value of investments in those companies. In addition, certain companies may operate in, or have dealings with, countries that the U.S. Government has identified as state sponsors of terrorism. As a result, such companies may be subject to specific constraints or regulations under U.S. law and, additionally, may be subject to negative investor perception, either of which could adversely affect such companies' performance.
Regulatory Risk. Foreign companies may not be registered with the U.S. Securities and Exchange Commission (SEC) and are generally not subject to the regulatory controls and disclosure requirements imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Foreign companies may not be subject to uniform accounting, auditing and financial reporting standards, corporate governance practices and requirements comparable to those applicable to domestic companies. Therefore, financial information about foreign companies may be incomplete, or may not be comparable to the information available on U.S. companies. Income from foreign securities owned by the Funds may be reduced by a withholding tax at the source, which tax would reduce dividend income payable to Fund shareholders.
There is generally less government supervision and regulation of securities exchanges, brokers, dealers, and listed companies in foreign countries than in the U.S., thus increasing the risk of delayed settlements of portfolio transactions or loss of certificates for portfolio securities. Foreign markets may also have different clearance and settlement procedures. If a Fund experiences settlement problems, it may result in temporary periods when a portion of the Fund’s assets are uninvested and could cause the Fund to miss attractive investment opportunities or a potential liability to the Fund arising out of the Fund’s inability to fulfill a contract to sell such securities.
Market Risk. Investing in foreign markets generally involves certain risks not typically associated with investing in the United States. The securities markets in many foreign countries will have substantially lower trading volume than the U.S. markets. As a result, the securities of some foreign companies may be less liquid and experience more price volatility than comparable domestic securities. Obtaining and/or enforcing judgments in foreign countries may be more difficult, and there is generally less government regulation and supervision of foreign stock exchanges, brokers and issuers, each of which may make it more difficult to enforce contractual obligations. Increased custodian costs as well as administrative costs (such as the need to use foreign custodians) may also be associated with the maintenance of assets in foreign jurisdictions. In addition, transaction costs in foreign securities markets are likely to be higher, since brokerage commission rates in foreign countries are likely to be higher than in the United States.

Debt Investments
U.S. Government Obligations. U.S. Government obligations include obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury, as well as “stripped” or “zero coupon” U.S. Treasury obligations.
U.S. Government obligations may be, (i) supported by the full faith and credit of the U.S. Treasury, (ii) supported by the right of the issuer to borrow from the U.S. Treasury, (iii) supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations, or (iv) supported only by the credit of the instrumentality. There is a risk that the U.S. Government may choose not to provide financial support to U.S. Government-sponsored agencies or instrumentalities if it is not legally obligated to do so. In that case, if the issuer were to default, a Fund holding securities of such issuer might not be able to recover its investment from the U.S. Government. For example, while the U.S. Government has provided financial support to Federal National Mortgage Association (FNMA) and Federal Home Loan Mortgage Corporation (FHLMC), no assurance can be given that the U.S. Government will always do so, since the U.S. Government is not so obligated by law. There also is no guarantee that the government would support Federal Home Loan Banks. Accordingly, securities of FNMA, FHLMC and Federal Home Loan Banks, and other agencies, may involve a risk of non-payment of principal and interest. Any downgrade of the credit rating of the securities issued by the U.S. Government may result in a downgrade of securities issued by its agencies or instrumentalities, including government-sponsored entities. Additionally, from time to time uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt limit, commonly called the “debt ceiling,” could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury securities, and/or increase the costs of various kinds of debt. If a U.S. government-sponsored entity is negatively impacted by legislative or regulatory action, is unable to meet its obligations, or its creditworthiness declines, the performance of a Fund that holds securities of that entity will be adversely impacted.
Temporary Investments. Each Fund may invest a portion of its assets in affiliated money market funds or in other types of money market instruments in which those funds would invest or other short-term U.S. Government securities for cash management purposes. Each Fund may invest up to 100% of its assets in investments that may be inconsistent with the Fund's principal investment strategies for temporary defensive purposes in anticipation of or in response to adverse market, economic, political or other conditions, or atypical circumstances such as unusually large cash inflows or redemptions. As a result, a Fund may not achieve its investment objective.
Low or Negative Interest Rates. In a low or negative interest rate environment, debt securities may trade at, or be issued with, negative yields, which means the purchaser of the security may receive at maturity less than the total amount invested. In addition, in a negative interest rate environment, if a bank charges negative interest, instead of receiving interest on deposits, a depositor must pay the bank fees to keep money with the bank. To the extent a Fund holds a negatively-yielding debt security or has a bank deposit with a negative interest rate, the Fund would generate a negative return on that investment. Cash positions may also subject a Fund to increased counterparty risk to the Fund's bank. Debt market conditions are highly unpredictable and some parts of the market are subject to dislocations. In response to recent market volatility and economic uncertainty arising from the COVID-19 pandemic, the U.S. government and certain foreign central banks have taken steps to stabilize markets by, among other things, reducing interest rates. As a result, interest rates in the United States are at historically low levels, and certain foreign countries have pursued negative interest rate policies. These actions present heightened risks to debt securities, and such risks could be even further heightened if these actions are unexpectedly or suddenly reversed or are ineffective in achieving their desired outcomes.
If low or negative interest rates become more prevalent in the market and/or if low or negative interest rates persist for a sustained period of time, some investors may seek to reallocate assets to other income-producing assets. This may cause the price of such higher yielding instruments to rise, could further reduce the value of instruments with a negative yield, and may limit a Fund's ability to locate fixed income
7

instruments containing the desired risk/return profile. Changing interest rates, including, rates that fall below zero, could have unpredictable effects on the markets and may expose fixed income markets to heightened volatility, increased redemptions, and potential illiquidity.
With respect to a money market fund, which seeks to maintain a stable $1.00 price per share, a low or negative interest rate environment could impact the money market fund’s ability to maintain a stable $1.00 share price. During a low or negative interest rate environment, such money market fund may reduce the number of shares outstanding on a pro rata basis through reverse stock splits, negative dividends or other mechanisms to seek to maintain a stable $1.00 price per share, to the extent permissible by applicable law and its organizational documents. Alternatively, the money market fund may discontinue using the amortized cost method of valuation to maintain a stable $1.00 price per share and establish a fluctuating NAV per share rounded to four decimal places by using available market quotations or equivalents.
Asset-Backed Securities. Asset-backed securities are interests in pooled mortgages, loans, receivables, or other assets. Payments of interest and repayment of principal may be largely dependent upon the cash flows generated by the assets backing the securities and, in certain cases, supported by letters of credit, surety bonds, or other credit enhancements. Asset-backed security values may also be affected by other factors including changes in interest rates, the availability of information concerning the pool and its structure, the creditworthiness of the servicing agent for the pool, the originator of the loans or receivables, or the entities providing the credit enhancement.
Bank Instruments. Bank instruments are unsecured interest bearing bank deposits. Bank instruments include, but are not limited to, certificates of deposit, time deposits, and banker’s acceptances from U.S. or foreign banks, as well as Eurodollar CDs and Eurodollar time deposits of foreign branches of domestic banks. Some certificates of deposit are negotiable interest-bearing instruments with a specific maturity issued by banks and savings and loan institutions in exchange for the deposit of funds, and can typically be traded in the secondary market prior to maturity. Other certificates of deposit, like time deposits, are non-negotiable receipts issued by a bank in exchange for the deposit of funds which earns a specified rate of interest over a definite period of time; however, it cannot be traded in the secondary market. A banker’s acceptance is a bill of exchange or time draft drawn on and accepted by a commercial bank.
An investment in Eurodollar CDs or Eurodollar time deposits may involve some of the same risks that are described for Foreign Debt Securities.
Synthetic Municipal Instruments. The Funds may invest in synthetic municipal instruments, the value of and return on which are derived from underlying securities.  Synthetic municipal instruments in which the Fund may invest include tender option bonds, and fixed or variable rate trust certificates. These types of instruments involve the deposit into a trust or custodial account of one or more long-term tax-exempt bonds or notes (Underlying Bonds), and the sale of certificates evidencing interests in the trust or custodial account to investors such as the Funds. The trustee or custodian receives the long-term fixed rate interest payments on the Underlying Bonds, and pays certificate holders fixed rates or short-term floating or variable interest rates which are reset periodically. A “tender option bond” provides a certificate holder with the conditional right to sell its certificate to the sponsor or some designated third party at specified intervals and receive the par value of the certificate plus accrued interest (a demand feature). A fixed rate trust certificate evidences an interest in a trust entitling a certificate holder to fixed future interest and/or principal payments on the Underlying Bonds. A “variable rate trust certificate” evidences an interest in a trust entitling the certificate holder to receive variable rate interest based on prevailing short-term interest rates and also typically provides the certificate holder with the conditional demand feature (the right to tender its certificate at par value plus accrued interest under certain conditions).
All synthetic municipal instruments must meet the minimum quality standards for the Funds' investments and must present minimal credit risks. In selecting synthetic municipal instruments for the Funds, Invesco considers the creditworthiness of the issuer of the Underlying Bond, the sponsor and the party providing certificate holders with a conditional right to sell their certificates at stated times and prices (a demand feature).
8

Typically, a certificate holder cannot exercise the demand feature until the occurrence of certain conditions, such as where the issuer of the Underlying Bond defaults on interest payments. Moreover, because synthetic municipal instruments involve a trust or custodial account and a third party conditional demand feature, they involve complexities and potential risks that may not be present where a municipal security is owned directly.
The tax-exempt character of the interest paid to certificate holders is based on the assumption that the holders have an ownership interest in the Underlying Bonds; however, the Internal Revenue Service (IRS) has not issued a ruling addressing this issue. In the event the IRS issues an adverse ruling or successfully litigates this issue, it is possible that the interest paid to the Funds on certain synthetic municipal instruments would be deemed to be taxable. The Funds rely on opinions of special tax counsel on this ownership question and opinions of bond counsel regarding the tax-exempt character of interest paid on the Underlying Bonds.
Municipal Securities. Municipal Securities are typically debt obligations of states, territories or possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, the interest on which, in the opinion of bond counsel or other counsel to the issuers of such securities, is, at the time of issuance, exempt from federal income tax. The issuers of municipal securities obtain funds for various public purposes, including the construction of a wide range of public facilities such as airports, highways, bridges, schools, hospitals, housing, mass transportation, streets and water and sewer works. Other public purposes for which municipal securities may be issued include refunding outstanding obligations, obtaining funds for general operating expenses and obtaining funds to lend to other public institutions and facilities.
Certain types of municipal securities are issued to obtain funding for privately operated facilities. The credit and quality of private activity debt securities are dependent on the private facility or user, who is responsible for the interest payment and principal repayment.
The two major classifications of Municipal Securities are bonds and notes. Municipal bonds are municipal debt obligations in which the issuer is obligated to repay the original (or “principal”) payment amount on a certain maturity date along with interest. A municipal bond’s maturity date (the date when the issuer of the bond repays the principal) may be years in the future. Short-term bonds mature in one to three years, while long-term bonds usually do not mature for more than a decade. Notes are short-term instruments which usually mature in less than two years. Most notes are general obligations of the issuing municipalities or agencies and are sold in anticipation of a bond sale, collection of taxes or receipt of other revenues. Municipal notes also include tax, revenue notes and revenue and bond anticipation notes (discussed more fully below) of short maturity, generally less than three years, which are issued to obtain temporary funds for various public purposes.
Municipal debt securities may also be classified as general obligation or revenue obligations (or "special delegation securities"). General obligation securities are secured by the issuer's pledge of its faith, credit and taxing power for the payment of principal and interest.
Revenue debt obligations, such as revenue bonds and revenue notes, are usually payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source but not from the general taxing power. The principal and interest payments for industrial development bonds or pollution control bonds are often the sole responsibility of the industrial user and therefore may not be backed by the taxing power of the issuing municipality. The interest paid on such bonds may be exempt from federal income tax, although current federal tax laws place substantial limitations on the purposes and size of such issues. Such obligations are considered to be Municipal Securities provided that the interest paid thereon, in the opinion of bond counsel, qualifies as exempt from federal income tax. However, interest on Municipal Securities may give rise to a federal alternative minimum tax (AMT) liability for noncorporate taxpayers and may have other collateral federal income tax consequences.  There is a risk that some or all of the interest received by the Fund from tax-exempt Municipal Securities might become taxable as a result of tax law changes or determinations of the IRS.
9

Another type of revenue obligations is pre-refunded bonds, which are typically issued to refinance debt. In other words, pre-refunded bonds result from the advance refunding of bonds that are not currently redeemable. The proceeds from the issue of the lower yield and/or longer maturing pre-refunding bond will usually be used to purchase U.S. Government obligations, such as U.S. Treasury securities, which are held in an escrow account and used to pay interest and principal payments until the scheduled call date of the original bond issue occurs. Like other fixed income securities, pre-refunded bonds are subject to interest rate, market, credit, and reinvestment risks. However, because pre-refunded bonds are generally collateralized with U.S. Government obligations, such pre-refunded bonds have essentially the same risks of default as a AAA-rated security. The Fund will treat such pre-refunded securities as investment-grade securities, notwithstanding the fact that the issuer of such securities may have a lower rating (such as a below-investment-grade rating) from one or more rating agencies.
Within these principal classifications of municipal securities, there are a variety of types of municipal securities, including but not limited to, fixed and variable rate securities, variable rate demand notes, municipal leases, custodial receipts, participation certificates, inverse floating rate securities, and derivative municipal securities.
After purchase by a Fund, an issue of Municipal Securities may cease to be rated by Moody's Investors Service, Inc. (Moody's) or S&P Global Ratings Services (S&P), or another nationally recognized statistical rating organization (NRSRO), or the rating of such a security may be reduced below the minimum credit quality rating required for purchase by the Fund. Neither event would require a Fund to dispose of the security. To the extent that the ratings applied by Moody’s, S&P or another NRSRO to Municipal Securities may change as a result of changes in these rating systems, a Fund will attempt to use comparable credit quality ratings as standards for its investments in Municipal Securities.
The yields on Municipal Securities are dependent on a variety of factors, including general economic and monetary conditions, money market factors, conditions of the Municipal Securities market, size of a particular offering, and maturity and rating of the obligation. Because many Municipal Securities are issued to finance similar projects, especially those related to education, health care, transportation and various utilities, conditions in those sectors and the financial condition of an individual municipal issuer can affect the overall municipal market. The market values of the Municipal Securities held by a Fund will be affected by changes in the yields available on similar securities. If yields increase following the purchase of a Municipal Security, the market value of such Municipal Security will generally decrease. Conversely, if yields decrease, the market value of a Municipal Security will generally increase. The ratings of S&P and Moody’s represent their opinions of the quality of the municipal securities they undertake to rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields while municipal securities of the same maturity and coupon with different ratings may have the same yield.
Certain of the municipal securities in which the Funds may invest represent relatively recent innovations in the municipal securities markets and the markets for such securities may be less developed than the market for conventional fixed rate municipal securities.
Under normal market conditions, longer-term municipal securities generally provide a higher yield than shorter-term municipal securities. The Funds have no limitation as to the maturity of municipal securities in which they may invest. The Adviser may adjust the average maturity of a Fund’s portfolio from time to time depending on its assessment of the relative yields available on securities of different maturities and its expectations of future changes in interest rates.
The net asset value of a Fund will change with changes in the value of its portfolio securities. With fixed income municipal securities, the net asset value of a Fund can be expected to change as general levels of interest rates fluctuate. When interest rates decline, the value of a portfolio invested in fixed income securities generally can be expected to rise. Conversely, when interest rates rise, the value of a portfolio invested in fixed income securities generally can be expected to decline. The prices of longer term municipal securities generally are more volatile with respect to changes in interest rates than the prices of shorter term municipal securities. Volatility may be greater during periods of general economic uncertainty.
10

Municipal Securities, like other debt obligations, are subject to the credit risk of nonpayment. The ability of issuers of municipal securities to make timely payments of interest and principal may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such nonpayment would result in a reduction of income to a Fund, and could result in a reduction in the value of the municipal securities experiencing nonpayment and a potential decrease in the net asset value of the Fund. In addition, a Fund may incur expenses to work out or restructure a distressed or defaulted security.
The Funds may invest in Municipal Securities with credit enhancements such as letters of credit and municipal bond insurance. The Funds may invest in Municipal Securities that are insured by financial insurance companies. Since a limited number of entities provide such insurance, a Fund may invest more than 25% of its assets in securities insured by the same insurance company. If a Fund invests in Municipal Securities backed by insurance companies and other financial institutions, changes in the financial condition of these institutions could cause losses to the Fund and affect share price. Letters of credit are issued by a third party, usually a bank, to enhance liquidity and ensure repayment of principal and any accrued interest if the underlying Municipal Bond should default. These credit enhancements do not guarantee payments or repayments on the Municipal Securities and a downgrade in the credit enhancer could affect the value of the Municipal Security.
If the IRS determines that an issuer of a Municipal Security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result 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. For example, 2017 legislation commonly known as the Tax Cuts and Jobs Act repeals the exclusion from gross income for interest on pre-refunded municipal securities effective for such bonds issued after December 31, 2017.
Taxable municipal securities are debt securities issued by or on behalf of states and their political subdivisions, the District of Columbia, and possessions of the United States, the interest on which is not exempt from federal income tax. Taxable investments include, for example, hedging instruments, repurchase agreements, and many of the types of securities the Fund would buy for temporary defensive purposes.
At times, in connection with the restructuring of a municipal bond issuer either outside of bankruptcy court in a negotiated workout or in the context of bankruptcy proceedings, the Fund may determine or be required to accept equity or taxable debt securities, or the underlying collateral (which may include real estate or loans) from the issuer in exchange for all or a portion of the Fund’s holdings in the municipal security. Although the Adviser will attempt to sell those assets as soon as reasonably practicable in most cases, depending upon, among other things, the Adviser’s valuation of the potential value of such assets in relation to the price that could be obtained by the Fund at any given time upon sale thereof, the Fund may determine to hold such securities or assets in its portfolio for limited period of time in order to liquidate the assets in a manner that maximizes their value to the Fund.
Municipal Securities also include the following securities:
Bond Anticipation Notes usually are general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds.
Revenue Anticipation Debt Securities, including bonds, notes, and certificates, are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the securities. In general, they also constitute general obligations of the issuer.
Tax Anticipation Notes are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues.
11

Tax-Exempt Commercial Paper (Municipal Paper) is similar to taxable commercial paper, except that tax-exempt commercial paper is issued by states, municipalities and their agencies.
Tax-Exempt Mandatory Paydown Securities (TEMPS) are fixed rate term bonds carrying a short-term maturity, usually three to four years beyond the expected redemption. TEMPS are structured as bullet repayments, with required optional redemptions as entrance fees are collected.
Zero Coupon and Pay-in-Kind Securities do not immediately produce cash income. These securities are issued at an original issue discount, with the full value, including accrued interest, paid at maturity. Interest income may be reportable annually, even though no annual payments are made. Market prices of zero coupon bonds tend to be more volatile than bonds that pay interest regularly. Pay-in-kind securities are securities that have interest payable by delivery of additional securities. Upon maturity, the holder is entitled to receive the aggregate par value of the securities. Zero coupon and pay-in-kind securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities paying cash interest at regular interest payment periods. Prices on non-cash-paying instruments may be more sensitive to changes in the issuer’s financial condition, fluctuation in interest rates and market demand/supply imbalances than cash-paying securities with similar credit ratings, and thus may be more speculative. Special tax considerations are associated with investing in certain lower-grade securities, such as zero coupon or pay-in-kind securities.
Capital Appreciation Bonds are municipal securities in which the investment return on the initial principal payment is reinvested at a compounded rate until the bond matures. The principal and interest are due on maturity. Thus, like zero coupon securities, investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks.
Payments in lieu of taxes (also known as PILOTs) are voluntary payments by, for instance the U.S. Government or nonprofits, to local governments that help offset losses in or otherwise serve as a substitute for property taxes.
Converted Auction Rate Securities (CARS) are a structure that combines the debt service deferral feature of Capital Appreciation Bonds (CABS) with Auction Rate Securities. The CARS pay no debt service until a specific date, then they incrementally convert to conventional Auction Rate Securities. At each conversion date the issuer has the ability to call and pay down any amount of the CARS.
    Some bonds may be “callable,” allowing the issuer to redeem them before their maturity date. To protect bondholders, callable bonds may be issued with provisions that prevent them from being called for a period of time. Typically, that is 5 to 10 years from the issuance date. When interest rates decline, if the call protection on a bond has expired, it is more likely that the issuer may call the bond. If that occurs, the Fund might have to reinvest the proceeds of the called bond in investments that pay a lower rate of return, which could reduce the Fund’s yield.
U.S. Corporate Debt Obligations. Corporate debt obligations are debt obligations issued or guaranteed by corporations that are denominated in U.S. dollars. Such investments may include, among others, commercial paper, bonds, notes, debentures, variable rate demand notes, master notes, funding agreements and other short-term corporate instruments. Commercial paper consists of short-term promissory notes issued by corporations. Commercial paper may be traded in the secondary market after its issuance. Variable rate demand notes are securities with a variable interest which is readjusted on pre-established dates. Variable rate demand notes are subject to payment of principal and accrued interest (usually within seven days) on a Fund’s demand. Master notes are negotiated notes that permit the investment of fluctuating amounts of money at varying rates of interest pursuant to arrangements with issuers who meet the credit quality criteria of the Fund. The interest rate on a master note may fluctuate based upon changes in specified interest rates or be reset periodically according to a prescribed formula or may be a set rate. Although there is no secondary market in master notes, if such notes have a demand feature, the payee may demand payment of the principal amount of the note upon relatively short notice. Funding agreements are agreements between an insurance company and a Fund covering underlying demand notes. Although there is no secondary market in
12

funding agreements, if the underlying notes have a demand feature, the payee may demand payment of the principal amount of the note upon relatively short notice. Master notes and funding agreements are generally illiquid and therefore subject to the Funds' percentage limitation for illiquid investments.
Other Investments
Other Investment Companies. Unless otherwise indicated in this SAI or in a Fund’s prospectus, each Fund may purchase shares of other investment companies. For each Fund, the 1940 Act imposes the following restrictions on investments in other investment companies: (i) a Fund may not purchase more than 3% of the total outstanding voting stock of another investment company; (ii) a Fund may not invest more than 5% of its total assets in securities issued by another investment company; and (iii) a Fund may not invest more than 10% of its total assets in securities issued by other investment companies. The 1940 Act and related rules provide certain exemptions from these restrictions. For example, under certain conditions, a Fund may acquire an unlimited amount of shares of mutual funds that are part of the same group of investment companies as the acquiring fund. In addition, these restrictions do not apply to investments by the Funds in investment companies that are money market funds, including money market funds that have Invesco or an affiliate of Invesco as an investment adviser (the Affiliated Money Market Funds).
When a Fund purchases shares of another investment company, including an Affiliated Money Market Fund, the Fund will indirectly bear its proportionate share of the advisory fees and other operating expenses of such investment company and will be subject to the risks associated with the portfolio investments of the underlying investment company.
In October 2020, the SEC adopted a new regulatory framework, including new Rule 12d1-4 under the 1940 Act, for fund-of-funds arrangements. This new regulatory framework includes, among other things, the rescission of certain SEC exemptive orders and rules permitting investments in excess of the statutory limits and the withdrawal of certain related SEC staff no-action letters. The rescission of exemptive relief is effective January 19, 2022. After such time, the Funds will no longer be able to rely on the aforementioned exemptive orders and will be subject instead to Rule 12d1-4 and other applicable rules. These regulatory changes may adversely impact a Fund’s investment strategies and operations to the extent that it invests, or might otherwise have invested, in shares issued by other investment companies.
Variable or Floating Rate Instruments. Variable or floating rate instruments are securities that provide for a periodic adjustment in the interest rate paid on the obligation. The interest rates for securities with variable interest rates are readjusted on set dates (such as the last day of the month or calendar quarter) and the interest rates for securities with floating rates are reset whenever a specified interest rate change occurs. Variable or floating interest rates generally reduce changes in the market price of securities from their original purchase price because, upon readjustment, such rates approximate market rates. Accordingly, as market interest rates decrease or increase, the potential for capital appreciation or depreciation is less for variable or floating rate securities than for fixed rate obligations. Many securities with variable or floating interest rates have a demand feature allowing the Fund to demand payment of principal and accrued interest prior to its maturity. The terms of such demand instruments require payment of principal and accrued interest by the issuer, a guarantor, and/or a liquidity provider. All variable or floating rate instruments will meet the applicable rating standards of the Funds. A Fund’s Adviser, or Sub-Adviser, as applicable, may determine that an unrated floating rate or variable rate demand obligation meets the Fund’s rating standards by reason of being backed by a letter of credit or guarantee issued by a bank that meets those rating standards.
For Rule 2a-7 purposes, a variable rate security, the principal amount of which is scheduled to be paid in more than 397 calendar days, that is subject to a demand feature, shall be deemed to have a maturity equal to the longer of the period remaining until the next readjustment of the interest rate or the period remaining until the principal amount can be recovered through demand.  A floating rate security, the principal amount of which, in accordance with the terms of the security, must unconditionally be paid in 397 calendar days or less shall be deemed to have a maturity of one day.
The secondary market for certain floating rate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods (in some cases, longer than seven days).  Certain
13

floating rate loans held by a Fund might not be considered securities for purposes of the 1933 Act or the Exchange Act of 1934 and therefore a risk exists that purchasers such as the Funds, may not be entitled to rely on the antifraud provisions of those Acts.
LIBOR Transition Risk
A Fund may invest in financial instruments (including variable or floating rate loans, debt securities, and derivatives such as interest rate futures) that are tied to the London Interbank Offered Rate (“LIBOR”). LIBOR is a common benchmark interest rate index used to make adjustments to variable-rate loans and to determine interest rates for a variety of financial instruments and borrowing arrangements. A Fund’s investments may pay interest at floating rates based on LIBOR, may be subject to interest caps or floors based on LIBOR, or may otherwise reference LIBOR as a reference rate to determine payment obligations, financing terms, hedging strategies or investment value.
On July 27, 2017, the head of the United Kingdom's Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. Although many LIBOR rates will be phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition. There remains uncertainty regarding the effect of the LIBOR transition process and therefore any impact of a transition away from LIBOR on a Fund or the instruments in which a Fund invests cannot yet be determined. There is no assurance that the composition or characteristics of any alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. As a result, the transition process might lead to increased volatility and reduced liquidity in markets that currently rely on LIBOR to determine interest rates; a reduction in the value of some LIBOR-based investments; increased difficulty in borrowing or refinancing and diminished effectiveness of any applicable hedging strategies against instruments whose terms currently include LIBOR; and/or costs incurred in connection with temporary borrowings and closing out positions and entering into new agreements. Additionally, while some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative or “fallback” rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments have such fallback provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. These effects could occur prior to the end of 2021 as the utility of LIBOR as a reference rate could deteriorate during the transition period. Any such effects of the transition away from LIBOR and the adoption of alternative reference rates could result in losses to a Fund.
Industry initiatives are underway to identify and begin implementation of alternative reference rates; however, there are challenges to converting certain securities and transactions to a new reference rate.
In June 2017, the Alternative Reference Rates Committee, a group of large U.S. banks working with the Federal Reserve, announced a replacement for LIBOR, the Secured Overnight Funding Rate (SOFR). The Federal Reserve Bank of New York began publishing the SOFR in April 2018, which is a broad measure of the cost of overnight borrowing of cash collateralized by Treasury securities. SOFR is intended to serve as a reference rate for U.S. dollar-based debt and derivatives and ultimately reduce the markets’ dependence on LIBOR. Bank working groups and regulators in other countries have suggested other alternatives for their markets, including the Sterling Overnight Interbank Average Rate in the United Kingdom. 
Environmental, Social and Governance (ESG) Considerations
The ESG considerations described herein may not be used by a Fund and will vary depending on a Fund's particular investment strategy and in accordance with what a Fund’s investment team deems relevant when making investment decisions. Further, a Fund’s prospectus may describe additional ESG strategies and risks.
ESG considerations, either quantitative or qualitative, may be utilized as a component of a Fund’s investment process to implement its investment strategy in pursuit of its investment objective. ESG factors
14

may be incorporated to evaluate an issuer, as part of risk analysis, credit analysis or in other manners. ESG factors may vary across types of investments and issuers, and not every ESG factor may be identified or evaluated. The incorporation of ESG factors may affect a Fund’s exposure to certain issuers or industries and may not work as intended. A Fund may underperform other funds that do not assess an issuer’s ESG factors as part of the investment process or that use a different methodology to identify and/or incorporate ESG factors. Because ESG considerations may be used as one part of an overall investment process, a Fund may still invest in securities of issuers that are not considered ESG-focused or that may be viewed as having a high ESG risk profile. As investors can differ in their views regarding ESG factors, a Fund may invest in issuers that do not reflect the views with respect to ESG of any particular investor. Information used by a Fund to evaluate such factors, including information from reliance on third-party research and/or proprietary research, may not be readily available, complete or accurate, and may vary across providers and issuers as ESG is not a uniformly defined characteristic, which could negatively impact a Fund’s ability to accurately assess an issuer, which could negatively impact a Fund’s performance. There is no guarantee that the evaluation of ESG considerations will be additive to a Fund’s performance. 
Investment Techniques
Forward Commitments, When-Issued and Delayed Delivery Securities. Each Fund may purchase and sell securities on a forward commitment, when-issued and delayed delivery basis whereby the Fund buys or sells a security with payment and delivery taking place in the future. Securities purchased or sold on a forward commitment, when-issued or delayed delivery basis involve delivery and payment that take place in the future after the date of the commitment to purchase or sell the securities at a pre-determined price and/or yield. Settlement of such transactions normally occurs a month or more after the purchase or sale commitment is made. Typically, no interest accrues to the purchaser until the security is delivered. Forward commitments also include “to be announced” (TBA) dollar roll transactions, which are contracts for the purchase or sale of mortgage-backed securities to be delivered at a future agreed upon date, whereby the specific mortgage-backed securities that will be delivered to fulfill the trade obligation or terms of the contract are not specifically identified at the time of the trade. A Fund may also enter into buy/sell back transactions (a form of delayed delivery agreement). In a buy/sell back transaction, a Fund enters a trade to sell securities at one price and simultaneously enters a trade to buy the same securities at another price for settlement at a future date. Although a Fund generally intends to acquire or dispose of securities on a forward commitment, when-issued or delayed delivery basis, a Fund may sell these securities or its commitment before the settlement date if deemed advisable. No specific limitation exists as to the percentage of the Fund’s assets which may be used to acquire securities on a when-issued and delayed delivery basis.
When purchasing a security on a forward commitment, when-issued or delayed delivery basis, a Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuation, and takes such fluctuations into account when determining its net asset value. Securities purchased on a forward commitment, when-issued or delayed delivery basis are subject to changes in value based upon the public’s perception of the creditworthiness of the issuer and changes, real or anticipated, in the level of interest rates. Accordingly, securities acquired on such a basis may expose a Fund to risks because they may experience such fluctuations prior to actual delivery. Purchasing securities on a forward commitment, when-issued or delayed delivery basis may involve the additional risk that the yield available in the market when the delivery takes place actually may be higher than that obtained in the transaction itself.
Many forward commitments, when-issued and delayed delivery transactions, including “to be announced” (TBAs), are also subject to the risk that a counterparty may become bankrupt or otherwise fail to perform its obligations due to financial difficulties, including making payments or fulfilling obligations to a Fund. A Fund may obtain no or only limited recovery in a bankruptcy or other organizational proceedings, and any recovery may be significantly delayed. With respect to forward settling TBA transactions involving U.S. Government agency mortgage-backed securities, the counterparty risk may be mitigated by the exchange of variation margin between the counterparties on a regular basis as the market value of the deliverable security fluctuates.
15

Investment in these types of securities may increase the possibility that the Fund will incur short-term gains subject to federal taxation or short-term losses if the Fund must engage in portfolio transactions in order to honor its commitment. Until the settlement date, a Fund will segregate liquid assets of a dollar value sufficient at all times to make payment for the forward commitment, when-issued or delayed delivery transactions. Such segregated liquid assets will be marked-to-market daily, and the amount segregated will be increased if necessary to maintain adequate coverage of the delayed delivery commitments. The delayed delivery securities, which will not begin to accrue interest or dividends until the settlement date, will be recorded as an asset of a Fund and will be subject to the risk of market fluctuation. The purchase price of the delayed delivery securities is a liability of a Fund until settlement. TBA transactions and transactions in other forward-settling mortgage-backed securities are effected pursuant to a collateral agreement with the seller. A Fund provides to the seller collateral consisting of cash or liquid securities in an amount as specified by the agreement upon initiation of the transaction. A Fund will make payments throughout the term of the transaction as collateral values fluctuate to maintain full collateralization for the term of the transaction. Collateral will be marked-to-market every business day. If the seller defaults on the transaction or declares bankruptcy or insolvency, a Fund might incur expenses in enforcing its rights, or the Fund might experience delay and costs in recovering collateral or may suffer a loss of principal and interest if the value of the collateral declines. In these situations, a Fund will be subject to greater risk that the value of the collateral will decline before it is recovered or, in some circumstances, the Fund may not be able to recover the collateral, and the Fund will experience a loss.
Interfund Loans. The SEC has issued an exemptive order permitting the Invesco Funds to borrow money from and lend money to each other for temporary or emergency purposes. The Invesco Funds’ interfund lending program is subject to a number of conditions, including the requirements that: (1) an interfund loan generally will occur only if the interest rate on the loan is more favorable to the borrowing fund than the interest rate typically available from a bank for a comparable transaction and the rate is more favorable to the lending fund than the rate available on overnight repurchase transactions; (2) an Invesco Fund may not lend more than 15% of its net assets through the program (measured at the time of the last loan); and (3) an Invesco Fund may not lend more than 5% of its net assets to another Invesco Fund through the program (measured at the time of the loan). A Fund may participate in the program only if and to the extent that such participation is consistent with the Fund’s investment objective and investment policies. Interfund loans have a maximum duration of seven days. Loans may be called with one day’s notice and may be repaid on any day.
Borrowing. The Funds may borrow money to the extent permitted under the 1940 Act Laws, Interpretations and Exemptions (defined below) and Fund Policies. Such borrowings may be utilized (i) for temporary or emergency purposes; (ii) in anticipation of or in response to adverse market conditions; or, (iii) for cash management purposes. All borrowings are limited to an amount not exceeding 33 1/3% of a Fund's total assets (including the amount borrowed) less liabilities (other than borrowings). Any borrowings that exceed this amount will be reduced within three business days to the extent necessary to comply with the 33 1/3% limitation even if it is not advantageous to sell securities at that time.
If there are unusually heavy redemptions, a Fund may have to sell a portion of its investment portfolio at a time when it may not be advantageous to do so. Selling Fund securities under these circumstances may result in a lower net asset value per share or decreased dividend income, or both. Invesco and the Sub-Advisers believe that, in the event of abnormally heavy redemption requests, a Fund's borrowing ability would help to mitigate any such effects and could make the forced sale of their portfolio securities less likely.
The Funds may borrow from a bank, broker-dealer, or another Invesco Fund. Additionally, the Funds are permitted to temporarily carry a negative or overdrawn balance in their account with their custodian bank. To compensate the custodian bank for such overdrafts, the Funds may either (i) leave funds as a compensating balance in their account so the custodian bank can be compensated by earning interest on such funds; or (ii) compensate the custodian bank by paying it an agreed upon rate. A Fund may not purchase additional securities when any borrowings from banks or broker-dealers exceed 5% of the Fund's total assets or when any borrowings from an Invesco Fund are outstanding.
16

Repurchase Agreements. Each Fund, except for Invesco Treasury Obligations Portfolio and Invesco Tax-Free Cash Reserve Portfolio, may engage in repurchase agreement transactions involving the types of securities in which it is permitted to invest. Repurchase agreements are agreements under which a Fund acquires ownership of a security from a broker-dealer or bank that agrees to repurchase the security at a mutually agreed upon time and price (which is higher than the purchase price), thereby determining the yield during a Fund's holding period. A Fund may enter into a “continuing contract” or “open” repurchase agreement under which the seller is under a continuing obligation to repurchase the underlying securities from the Fund on demand and the effective interest rate is negotiated on a daily basis. Repurchase agreements may be viewed as loans made by a Fund which are collateralized by the securities subject to repurchase.
In any repurchase transaction, collateral for a repurchase agreement may include cash items or Government Securities. The Funds consider repurchase agreements with the Federal Reserve Bank of New York to be U.S. Government Securities for purposes of the Funds’ investment policies. Additionally, the Funds consider federal agency mortgage-backed securities to be Government Securities. The Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio may also engage in repurchase agreements collateralized by securities that are rated investment grade and below investment grade by NRSROs or unrated securities of comparable quality, loan participations, and equities (collectively, “other collateral”). For these types of repurchase agreement transactions, the Fund would look to the counterparty, and not the collateral, for determining diversification under Rule 2a-7. Thus, collateral for a repurchase agreement may include securities that a Fund could not hold directly. Repurchase agreements involving obligations of other collateral may be subject to special risks and may not have the benefit of certain protections in the event of a counterparty’s insolvency.
Regardless of the collateral underlying the repurchase agreement, the Fund must determine that the repurchase agreement with the particular counterparty involves minimal credit risk and satisfies the credit quality standards in compliance with Rule 2a-7 under the 1940 Act.  Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities.  If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral.
If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, a Fund might incur expenses in enforcing its rights, and could experience a loss on the sale of the underlying security to the extent that the proceeds of the sale including accrued interest are less than the resale price provided in the agreement, including interest. In addition, although the Bankruptcy Code and other insolvency laws may provide certain protections for some types of repurchase agreements, if the seller of a repurchase agreement should be involved in bankruptcy or insolvency proceedings, a Fund may incur delay and costs in selling the underlying security or may suffer a loss of principal and interest if the value of the underlying security declines or the Fund may be deemed to be an unsecured creditor and be required to return the securities to the seller. The Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio may enter into repurchase agreements that involves securities that may be subject to a court ordered or other “stay” in the event of the seller’s bankruptcy or insolvency. A “stay” will prevent a Fund from selling the securities it holds under a repurchase agreement until permitted by a court or other authority. In these situations, a Fund may be subject to greater risk that the value of the securities may decline before they are sold, and that the Fund may experience a loss.
The securities underlying a repurchase agreement will be marked-to-market every business day so that the value of such securities is at least equal to the investment value of the repurchase agreement, including any accrued interest thereon. Custody of the securities will be maintained by the Fund’s custodian or sub-custodian for the duration of the agreement.
The Funds may invest their cash balances in joint accounts with other Invesco Funds for the purpose of investing in repurchase agreements with maturities not to exceed 60 days and collateralized by cash or Government Securities, and in certain other money market instruments with remaining maturities not to exceed 90 days. Repurchase agreements may be considered loans by a Fund under the 1940 Act.
17

Restricted and Illiquid Investments. Each Fund may not acquire any illiquid security if, immediately after the acquisition, the Fund would have invested more than 5% of its total assets in illiquid investments. For purposes of each Fund’s 5% limitation, an illiquid security means a security that cannot be sold or disposed of in the ordinary course of business within seven calendar days at approximately the value ascribed to it by the Fund, as determined pursuant to the 1940 Act and applicable rules and regulations thereunder.
Limitations on the resale of restricted investments may have an adverse effect on their marketability, which may prevent a Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering such securities for resale, and the risk of substantial delays in effecting such registrations. A Fund’s difficulty valuing and selling restricted securities or illiquid investments may result in a loss or be costly to the Fund.
If a substantial market develops for a restricted security or illiquid investment held by a Fund, it may be treated as a liquid investment, in accordance with procedures and guidelines adopted by the Board on behalf of the Funds.
Rule 144A Securities. Rule 144A securities are securities which, while privately placed, are eligible for purchase and resale pursuant to Rule 144A under the 1933 Act. This Rule permits certain qualified institutional buyers, such as the Funds, to trade in privately placed securities even though such securities are not registered under the 1933 Act. Fund will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund’s restriction on illiquid investments. The determination of whether a Rule 144A security is liquid or illiquid will take into account relevant market trading, and investment-specific considerations consistent with applicable SEC guidance. Additional factors that may be considered include the (i) frequency of trades and quotes; (ii) number of dealers and potential purchasers; (iii) dealer undertakings to make a market; and (iv) nature of the security and of market place trades (for example, the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer). Investing in Rule 144A securities could increase the amount of a Fund’s illiquid investments if qualified institutional buyers are unwilling to purchase such securities.
Sale of Money Market Securities. The Funds do not seek profits through short-term trading and will generally hold portfolio securities to maturity. However, the Adviser and/or Sub-Adviser may seek to enhance the yield of the Fund by taking advantage of yield disparities that occur in the money markets. For example, market conditions frequently result in similar securities trading at different prices. Also, there frequently are differences in yields between various types of money market securities. The Adviser and/or Sub-Adviser may dispose of any portfolio security prior to its maturity if such disposition and reinvestment of proceeds are expected to enhance yield consistent with the Adviser’s and/or Sub-Adviser’s judgment as to desirable portfolio maturity structure. The Adviser and/or Sub-Adviser may also dispose of any portfolio security prior to maturity to meet redemption requests, and as a result of a revised credit evaluation of the issuer or other circumstances or considerations. This procedure may increase or decrease the Fund’s yield depending upon the Adviser’s and/or Sub-Adviser’s ability to correctly time and execute such transactions. The Fund’s policy of investing in securities with maturities of 397 calendar days (60 calendar days for Invesco STIC Prime Portfolio) or less will result in high portfolio turnover. Since brokerage commissions are not normally paid on investments of the type made by the Fund, the high turnover should not adversely affect the Fund’s net income.
Receipt of Issuer’s Nonpublic Information
The Adviser or Sub-Advisers (through their portfolio managers, analysts, or other representatives) may receive material nonpublic information about an issuer that may restrict the ability of the Adviser or Sub-Advisers to cause the Funds to buy or sell securities of the issuer on behalf of the Funds for substantial periods of time. This may impact the Funds' ability to realize profit or avoid loss with respect to the issuer and may adversely affect the Funds' flexibility with respect to buying or selling securities, potentially impacting Fund performance. For example, activist investors of certain issuers in which the Adviser or Sub-Advisers hold large positions may contact representatives of the Adviser or Sub-Advisers and may disclose material nonpublic information in such communication. The Adviser or Sub-Advisers would be restricted from trading
18

on the basis of such material nonpublic information, limiting their flexibility in managing the Funds and possibly impacting Fund performance.
Cybersecurity Risk
The Funds, like all companies, may be susceptible to operational and information security risks. Cybersecurity failures or breaches of the Funds or their service providers or the issuers of securities in which the Funds invest, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. The Funds and their shareholders could be negatively impacted as a result.
Business Continuity and Operational Risk
The Adviser, the Funds and the Funds’ service providers may experience disruptions or operating errors, such as processing errors or human errors, inadequate or failed internal or external processes, systems or technology failures, or other disruptive events, that could negatively impact and cause disruptions in normal business operations of the Adviser, the Funds or the Funds’ service providers. The Adviser has developed a Business Continuity Program (the “Program”) designed to minimize the disruption of normal business operations in the event of an adverse incident affecting the Funds, the Adviser and/or its affiliates. The Program is also designed to enable the Adviser to reestablish normal business operations in a timely manner during such an adverse incident; however, there are inherent limitations in such programs (including the possibility that contingencies have not been anticipated and procedures do not work as intended) and, under some circumstances (e.g. natural disasters, terrorism, public health crises, power or utility shortages and failures, system failures or malfunctions), the Adviser, its affiliates, and any service providers or vendors used by the Adviser, its affiliates, or the Fund could be prevented or hindered from providing services to the Funds for extended periods of time. These circumstances could cause disruptions and negatively impact the Funds’ service providers and the Funds’ business operations, potentially including an inability to process Fund shareholder transactions, an inability to calculate a Fund’s net asset value and price the Fund’s investments, and impediments to trading portfolio securities.
Natural Disaster/Epidemic Risk
Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis and other severe weather-related phenomena generally, and widespread disease, including pandemics and epidemics, have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the Funds’ investments. Given the increasing interdependence among global economies and markets, conditions in one country, market, or region are increasingly likely to adversely affect markets, issuers, and/or foreign exchange rates in other countries, including the U.S. These disruptions could prevent the Funds from executing advantageous investment decisions in a timely manner and negatively impact the Funds’ ability to achieve their investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Funds.
COVID-19. The current outbreak of the novel strain of coronavirus, COVID-19, has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs.  Efforts to contain the spread of COVID-19 have resulted in travel restrictions, closed international borders, disruptions of healthcare systems, business operations and supply chains, layoffs, lower consumer demand, defaults and other significant economic impacts, all of which have disrupted global economic activity across many industries and may exacerbate other pre-existing political, social and economic risks, locally or globally. The ongoing effects of COVID-19 are unpredictable and may result in significant and prolonged effects on a Fund's performance.

Fund Policies
Fundamental Restrictions. Except as otherwise noted below, each Fund is subject to the following investment restrictions, which may be changed only by a vote of such Fund’s outstanding shares. Fundamental restrictions may be changed only by a vote of the lesser of (i) 67% or more of the Fund’s shares present at a meeting if the holders of more than 50% of the outstanding shares are present in person or represented by proxy, or (ii) more than 50% of the Fund’s outstanding shares. Any fundamental investment restriction that involves a maximum or minimum percentage of securities or assets (other than with respect to borrowing shall not be considered to be violated unless an excess over or a deficiency under the percentage occurs immediately after, and is caused by an acquisition or disposition of securities or utilization of assets by the Fund.
(1) The Fund is a “diversified company” as defined in the 1940 Act. The Fund will not purchase the securities of any issuer if, as a result, the Fund would fail to be a diversified company within the meaning of the 1940 Act, and the rules and regulations promulgated thereunder, as such statute, rules and regulations are amended from time to time or are interpreted from time to time by the SEC staff (collectively, the “1940 Act Laws and Interpretations”) or except to the extent that the Fund may be permitted to do so by exemptive order or similar relief (collectively, with the 1940 Act Laws and Interpretations, the “1940 Act Laws, Interpretations and Exemptions”). In complying with this restriction, however, the Fund may purchase securities of other investment companies to the extent permitted by the 1940 Act Laws, Interpretations and Exemptions.
(2) The Fund may not borrow money or issue senior securities, except as permitted by the 1940 Act Laws, Interpretations and Exemptions.
(3) The Fund may not underwrite the securities of other issuers. This restriction does not prevent the Fund from engaging in transactions involving the acquisition, disposition or resale of its portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act.
(4) The Fund will not make investments that will result in the concentration (as that term may be defined or interpreted by the 1940 Act Laws, Interpretations and Exemptions) of its investments in the securities of issuers primarily engaged in the same industry. This restriction does not limit the Fund’s investments in (i) obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities, or (ii) tax-exempt obligations issued by governments or political subdivisions of governments, or (iii) bank instruments. In complying with this restriction, the Fund will not consider a bank-issued guaranty or financial guaranty insurance as a separate security.
(5) The Fund may not purchase real estate or sell real estate unless acquired as a result of ownership of securities or other instruments. This restriction does not prevent the Fund from investing in issuers that invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein.
(6) Invesco Liquid Assets Portfolio, Invesco STIC Portfolio, and Invesco Treasury Portfolio may not purchase physical commodities or sell physical commodities unless acquired as a result of ownership of securities or other instruments. This restriction does not prevent the Fund from engaging in transactions involving futures contracts and options thereon or investing in securities that are secured by physical commodities.
Invesco Government & Agency Portfolio, Invesco Tax-Free Cash Reserve Portfolio and Invesco Treasury Obligations Portfolio may not purchase or sell physical commodities except to the extent permitted by the 1940 Act and any other governing statute, and by the rules thereunder, and by the SEC or other regulatory agency with authority over the Fund.
(7) The Fund may not make personal loans or loans of its assets to persons who control or are under common control with the Fund, except to the extent permitted by 1940 Act Laws, Interpretations and Exemptions. This restriction does not prevent the Fund from, among other things, purchasing debt
20

obligations, entering into repurchase agreements, loaning its assets to broker-dealers or institutional investors, or investing in loans, including assignments and participation interests.
(8) The Fund may, notwithstanding any other fundamental investment policy or limitation, invest all of its assets in the securities of a single open-end management investment company with substantially the same fundamental investment objectives, policies and restrictions as the Fund.
(9) Invesco Tax-Free Cash Reserve Portfolio will limit its purchases of municipal securities to “First Tier” securities, as such term is defined from time to time in Rule 2a-7 under the 1940 Act.
In 2015, the SEC adopted rule amendments that remove references to credit ratings from Rule 2a-7 under the 1940 Act. The amendments delete the distinction between a “First Tier” and “Second Tier” security from Rule 2a-7, and the related definitions, and replace them with a requirement that a fund limit its investments to “Eligible Securities” as defined in the amended version of Rule 2a-7 (See also "Rule 2a-7 Requirements" - "Quality" in the SAI). Effective no later than the compliance date of the rule amendments (October 14, 2016), the SEC's amendments removing references to credit ratings from Rule 2a-7 have the practical effect of eliminating the Invesco Tax-Free Cash Reserve Portfolio's restriction limiting its purchases of municipal securities to “First Tier” securities, as such term is defined from time to time in Rule 2a-7 under the 1940 Act.
(10) Invesco Tax-Free Cash Reserve Portfolio’s assets will be invested so that at least 80% of the Fund’s income will be exempt from federal income taxes.
The investment restrictions set forth above provide each of the Funds with the ability to operate under new interpretations of the 1940 Act or pursuant to exemptive relief from the SEC without receiving prior shareholder approval of the change. Even though each of the Funds has this flexibility, the Board has adopted non-fundamental restrictions for each of the Funds relating to certain of these restrictions which Invesco and, when applicable, the Sub-Advisers must follow in managing the Funds. Any changes to these non-fundamental restrictions, which are set forth below, require the approval of the Board.
Explanatory Note
For purposes of the Fund’s fundamental restriction related to industry concentration above, investments in tax-exempt municipal securities where the payment of principal and interest for such securities is derived solely from a specific project associated with an issuer that is not a governmental entity or a political subdivision of a government are subject to a Fund’s industry concentration policy.
For purposes of the Fund’s fundamental restriction related to physical commodities above, the Fund is currently permitted to invest in futures, swaps and other instruments on physical commodities to the extent disclosed in a Fund’s Prospectuses or this SAI.
Non-Fundamental Restrictions. Non-fundamental restrictions may be changed for any Fund without shareholder approval. The non-fundamental investment restrictions listed below apply to each of the Funds unless otherwise indicated.
(1) In complying with the fundamental restriction regarding issuer diversification, the Fund will not, with respect to 100% of its total assets, purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities, and securities issued by other investment companies), if, as a result, (i) more than 5% of the Fund’s total assets would be invested in the securities of that issuer except as permitted by Rule 2a-7 under the 1940 Act, or (ii) the Fund would hold more than 10% of the outstanding voting securities of that issuer. The Fund may purchase securities of other investment companies as permitted by the 1940 Act Laws, Interpretations and Exemptions.
In complying with the fundamental restriction regarding issuer diversification, any Fund that invests in municipal securities will regard each state (including the District of Columbia and Puerto Rico), territory and possession of the United States, each political subdivision, agency, instrumentality and authority thereof, and each multi-state agency of which a state is a member as a separate “issuer.” When the
21

assets and revenues of an agency, authority, instrumentality or other political subdivision are separate from the government creating the subdivision and the security is backed only by assets and revenues of the subdivision, such subdivision would be deemed to be the sole issuer. Similarly, in the case of an Industrial Development Bond or Private Activity Bond, if that bond is backed only by the assets and revenues of the non-governmental user, then that non-governmental user would be deemed to be the sole issuer.
(2) In complying with the fundamental restriction regarding industry concentration, the Fund may invest up to 25% of its total assets in the securities of issuers whose principal business activities are in the same industry and may invest over 25% of its assets in (i) obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities, (ii) tax-exempt obligations issued by governments or political subdivisions of governments, and (iii) bank instruments.
(3) Notwithstanding the fundamental restriction with regard to engaging in transactions involving futures contracts and options thereon or investing in securities that are secured by physical commodities, the Fund (except for Invesco Government & Agency Portfolio, Invesco Tax-Free Cash Reserve Portfolio and Invesco Treasury Obligations Portfolio) currently may not invest in any security (including futures contracts or options thereon) that are secured by physical commodities.
(4) In complying with the fundamental restriction with regard to making loans, the Fund may lend up to 33 1/3% of its total assets and may lend money to an Invesco Fund, on such terms and conditions as the SEC may require in an exemptive order.
(5) Notwithstanding the fundamental restriction with regard to investing all assets in an open-end fund, the Fund may not invest all of its assets in the securities of a single open-end management investment company with the same fundamental investment objectives, policies and restrictions as the Fund.
(6) The Fund may not acquire any securities of registered unit investment trusts in reliance on sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.
(7) The following applies:
(a) Invesco Treasury Portfolio invests under normal circumstances at least 80% of its assets in direct obligations of the U.S. Treasury including bills, notes and bonds, and repurchase agreements secured by those obligations.
(b) Invesco Government & Agency Portfolio invests under normal circumstances at least 80% of its assets 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, as well as repurchase agreements secured by those obligations.
(c) Invesco Treasury Obligations Portfolio invests under normal circumstances at least 80% of its assets in direct obligations of the U.S. Treasury, which include Treasury bills, notes and bonds, and in securities issued or guaranteed as to principal and interest by the U.S. Government or by its agencies or instrumentalities.
For purposes of the foregoing, “assets” means net assets, plus the amount of any borrowings for investment purposes. Each Fund will provide written notice to its shareholders prior to any change to this policy, as required by the 1940 Act Laws, Interpretations and Exemptions.
If a percentage restriction on the investment or use of assets set forth in the Prospectuses or this SAI is adhered to at the time a transaction is effected, later changes in percentage resulting from changing asset values will not be considered a violation. It is the intention of each Fund, unless otherwise indicated, that with respect to the Funds’ policies that are a result of application of law, the Fund will take advantage of the flexibility provided by rules or interpretations of the SEC currently in existence or promulgated in the future, or changes to such laws.

Policies and Procedures for Disclosure of Fund Holdings
The Board has adopted policies and procedures with respect to the disclosure of the Funds' portfolio holdings (the Holdings Disclosure Policy). Invesco and the Board may amend the Holdings Disclosure Policy at any time without prior notice. Details of the Holdings Disclosure Policy and a description of the basis on which employees of Invesco and its affiliates may release information about portfolio securities in certain contexts are provided below. As used in the Holdings Disclosure Policy and throughout the SAI, the term “portfolio holdings information” includes information with respect to the portfolio holdings of a Fund, including holdings that are derivatives and holdings held as short positions. Information generally excluded from “portfolio holdings information” includes, without limitation, (i) descriptions of allocations among asset classes, regions, countries, industries or sectors; (ii) aggregated data such as average or median ratios, market capitalization, credit quality or duration; (iii) performance attributions by asset class, country, industry or sector; (iv) aggregated risk statistics, analysis and simulations, such as stress testing; (v) the characteristics of the stock and bond components of a Fund’s portfolio holdings and other investment positions; (vi) the volatility characteristics of a Fund; (vii) information on how various weightings and factors contributed to Fund performance; (viii) various financial characteristics of a Fund or its underlying portfolio investments; and (ix) other information where, in the reasonable belief of the Funds' Chief Compliance Officer (or a designee), the release of such information would not present risks of dilution, arbitrage, market timing, insider trading or other inappropriate trading for the applicable Fund.
Public release of portfolio holdings. The Funds  make available to institutions that maintain accounts with the Funds, beneficial owners of the Fund shares and prospective investors (collectively, Qualified Persons) information regarding or derived from the Funds’ portfolio holdings.

Qualified Persons may obtain access to the website, as well as, the information noted above, by calling the distributor toll free at 1-800-659-1005, option 2. The Funds’ distributor’s vice president/sale and administration manager are authorized to determine whether any entity or individual is a Qualified Person or is acting on behalf of a Qualified Person, and to disclose portfolio information to such Qualified Person. If a beneficial owner who is not a record owner requests portfolio information, such information will be sent to the record owner for distribution to the beneficial owner. Existing shareholders can also obtain portfolio information (other than portfolio holdings) by calling the transfer agent toll free at 1-800-659-1005, option 1. Generally, employees of Invesco and its affiliates may not disclose such portfolio holdings until one day after they have been posted on http://www.invesco.com/us. For CAVU Securities Classes, please visit www.invesco.com/cavu.
The Funds will file monthly with the SEC portfolio holdings and other information about the Fund and its portfolio as of the last business day of the preceding month or any subsequent calendar day of such month within five business days of the end of each month.
Selective disclosure of portfolio holdings information pursuant to Non-Disclosure Agreement. Employees of Invesco and its affiliates may disclose non-public full portfolio holdings information on a selective basis only if Invesco approves the parties to whom disclosure of non-public full portfolio holdings information will be made. Invesco must determine that the proposed selective disclosure will be made for business purposes of the applicable Fund and is in the best interest of the applicable Fund’s shareholders. In making such determination, Invesco will address any perceived conflicts of interest between shareholders of such Fund and Invesco or its affiliates as part of granting its approval.
The Board exercises continuing oversight of the disclosure of Fund portfolio holdings information by (1) overseeing the implementation and enforcement of the Holdings Disclosure Policy and the Invesco Funds’ Code of Ethics by the Chief Compliance Officer (or his designee) of Invesco and the Invesco Funds and (2) considering reports and recommendations by the Chief Compliance Officer concerning any material compliance matters (as defined in Rule 38a-1 under the 1940 Act and Rule 206(4)-7 under the Investment Advisers Act of 1940, as amended (the Advisers Act)) that may arise in connection with the Holdings Disclosure Policy. Pursuant to the Holdings Disclosure Policy, the Board receives reports on the specific types of situations in which Invesco proposes to provide such selective disclosure and the situations where providing selective disclosure raises perceived conflicts of interest between shareholders of the applicable Fund and Invesco or its affiliates. In any specific situation where Invesco addresses a perceived conflict, Invesco will report to the Board on the persons to whom such disclosures are to be made and the treatment of such conflict before agreeing to provide selective disclosure.
24

Invesco discloses non-public full portfolio holdings information to the following persons in connection with the day-to-day operations and management of the funds advised by Invesco (the Invesco Funds):
Attorneys and accountants;
Securities lending agents;
Lenders to the Invesco Funds;
Rating and rankings agencies;
Persons assisting in the voting of proxies;
Invesco Funds’ custodians;
The Invesco Funds’ transfer agent(s) (in the event of a redemption in kind);
Pricing services, market makers, or other fund accounting software providers (to determine the price of investments held by an Invesco Fund);
Brokers identified by the Invesco Funds’ portfolio management team who provide execution and research services to the team;
Analysts hired to perform research and analysis for the Invesco Funds’ portfolio management team; and
Insurance companies which receive portfolio holdings information before Invesco posts portfolio holdings information to Invesco's website (to allow such insurance companies to post portfolio holdings information to their websites at approximately the same time that Invesco posts portfolio holdings information to Invesco's website).
In many cases, Invesco will disclose current portfolio holdings information on a daily basis to these persons. In these situations, Invesco has entered into non-disclosure agreements which provide that the recipient of the portfolio holdings information will maintain the confidentiality of such portfolio holdings information and will not trade on such information (Non-disclosure Agreements). Please refer to Appendix B for a list of examples of persons to whom Invesco provides non-public portfolio holdings information on an ongoing basis.
Invesco will also disclose non-public portfolio holdings information if such disclosure is required by applicable laws, rules or regulations, or by regulatory authorities having jurisdiction over Invesco and its affiliates or the Invesco Funds, and where there is no other way to transact the Funds' business without disclosure of such portfolio holdings information.
The Holdings Disclosure Policy provides that the Funds, Invesco or any other party in connection with the disclosure of portfolio holdings information will not request, receive or accept any compensation (including compensation in the form of the maintenance of assets in any Fund or other mutual fund or account managed by Invesco or one of its affiliates) for the selective disclosure of portfolio holdings information.
Disclosure of certain portfolio holdings information without Non-Disclosure Agreement. Invesco and its affiliates that provide services to the Funds, the Sub-Advisers and each of their employees may receive or have access to portfolio holdings information as part of the day to day operations of the Funds.
From time to time, employees of Invesco and its affiliates may express their views orally or in writing on one or more of the Funds' portfolio investments or may state that a Fund has recently purchased or sold, or continues to own, one or more investments. The investments subject to these views and statements may be ones that were purchased or sold since the date on which portfolio holdings was made available on the Fund’s website and therefore may not be reflected on the portfolio holdings information disclosed on the website. Such views and statements may be made to various persons, including members of the press, shareholders in the applicable Fund, persons considering investing in the applicable Fund or representatives of such shareholders or potential shareholders, such as fiduciaries of a 401(k) plan and their advisers. The nature and content of the views and statements provided to each of these persons may differ.
25

Disclosure of portfolio holdings information to traders. Additionally, employees of Invesco and its affiliates may disclose one or more of the investments held by a Fund when purchasing and selling investments through broker-dealers, futures commissions merchants, clearing agencies and other counterparties requesting bids on investments, obtaining price quotations on investments, or in connection with litigation involving the Funds' portfolio investments. Invesco does not enter into formal Non-Disclosure Agreements in connection with these situations; however, the Funds would not continue to conduct business with a person who Invesco believed was misusing the disclosed information.
Disclosure of portfolio holdings of other Invesco-managed products. Invesco and its affiliates manage products sponsored by companies other than Invesco, including investment companies, offshore funds, and separate accounts. In many cases, these other products are managed in a similar fashion to certain Invesco Funds (as defined herein) and thus have similar portfolio holdings. The sponsors of these other products managed by Invesco and its affiliates may disclose the portfolio holdings of their products at different times than Invesco discloses portfolio holdings for the Invesco Funds.

Management Information
The Trustees have the authority to take all actions that they consider necessary or appropriate in connection with oversight of the Trust, including, among other things, approving the investment objectives, investment policies and fundamental investment restrictions for the Funds. The Trust has entered into agreements with various service providers, including the Funds’ investment advisers, administrator, transfer agent, distributor and custodians, to conduct the day-to-day operations of the Funds. The Trustees are responsible for selecting these service providers, approving the terms of their contracts with the Funds, and exercising general oversight of these arrangements on an ongoing basis.
Certain Trustees and officers of the Trust are affiliated with Invesco and Invesco Ltd., the parent corporation of Invesco. All of the Trust’s executive officers hold similar offices with some or all of the other Trusts.
Leadership Structure and the Board of Trustees. The Board is currently composed of fourteen Trustees, including thirteen Trustees who are not “interested persons” of the Funds, as that term is defined in the 1940 Act (collectively, the Independent Trustees and each, an Independent Trustee). In addition to eight regularly scheduled meetings per year, the Board holds special meetings or informal conference calls to discuss specific matters that may require action prior to the next regular meeting. As discussed below, the Board has established four standing committees – the Audit Committee, the Compliance Committee, the Governance Committee and the Investments Committee (the Committees), to assist the Board in performing its oversight responsibilities.
The Board has appointed an Independent Trustee to serve in the role of Chair. The Chair’s primary role is to preside at meetings of the Board and act as a liaison with the Adviser and other service providers, officers, including the Senior Officer of the Trust, attorneys, and other Trustees between meetings. The Chair also participates in the preparation of the agenda for the meetings of the Board, is active with mutual fund industry organizations, and may perform such other functions as may be requested by the Board from time to time. Except for any duties specified pursuant to the Trust’s Declaration of Trust or By-laws, the designation of Chair does not impose on such Independent Trustee any duties, obligations or liability that is greater than the duties, obligations or liability imposed on such person as a member of the Board generally.
The Board believes that its leadership structure, including having an Independent Trustee as Chair, allows for effective communication between the Trustees and management, among the Trustees and among the Independent Trustees. The existing Board structure, including its Committee structure, provides the Independent Trustees with effective control over Board governance while also allowing them to receive and benefit from insight from the interested Trustee who is an active officer of the Funds’ investment adviser. The Board’s leadership structure promotes dialogue and debate, which the Board believes allows for the proper consideration of matters deemed important to the Funds and their shareholders and results in effective decision-making.
Risk Oversight. The Board considers risk management issues as part of its general oversight responsibilities throughout the year at its regular meetings and at regular meetings of its Committees. Invesco prepares regular reports that address certain investment, valuation and compliance matters, and the Board as
32

a whole or the Committees also receive special written reports or presentations on a variety of risk issues at the request of the Board, a Committee or the Senior Officer.
The Board also considers liquidity risk management issues as part of its general oversight responsibilities and oversees the Trust's liquidity risk through, among other things, receiving periodic reporting and presentations by Invesco personnel that address liquidity matters. As required by Rule 22e-4 under the 1940 Act, the Board, including a majority of the Independent Trustees, has approved the Trust's Liquidity Risk Management ("LRM") Program, which is reasonably designed to assess and manage the Trust's liquidity risk, and has appointed the LRM Program Administrator that is responsible for administering the LRM Program. The Board also reviews, no less frequently than annually, a written report prepared by the LRM Program Administrator that addresses, among other items, the operation of the program and assesses its adequacy and effectiveness of implementation.
The Audit Committee is apprised by, and discusses with, management its policies on risk assessment and risk management. Such discussion includes a discussion of the guidelines governing the process by which risks are assessed and managed and an identification of each Fund’s major financial risk exposures. In addition, the Audit Committee meets regularly with representatives of Invesco Ltd.’s internal audit group to review reports on their examinations of functions and processes within Invesco that affect the Funds. The Audit Committee also oversees the valuation of the Funds’ portfolio securities and receives reports from management regarding the valuation of the Funds’ portfolio securities as consistent with the Funds’ Pricing Procedures.
The Compliance Committee receives regular compliance reports prepared by Invesco’s compliance group and meets regularly with the Fund’s Chief Compliance Officer (CCO) to discuss compliance issues, including compliance risks. The Compliance Committee has recommended and the Board has adopted compliance policies and procedures for the Funds and for the Funds’ service providers. The compliance policies and procedures are designed to detect, prevent and correct violations of the federal securities laws.
The Governance Committee monitors the composition of the Board and each of its Committees and monitors the qualifications of the Trustees to ensure adherence to certain governance undertakings applicable to the Funds. In addition, the Governance Committee oversees an annual self-assessment of the Board and addresses governance risks, including insurance and fidelity bond matters, for the Trust.
The Investments Committee and its sub-committees receive regular written reports describing and analyzing the investment performance of the Invesco Funds. In addition, Invesco’s Chief Investment Officers and the portfolio managers of the Funds meet regularly with the Investments Committee or its sub-committees to discuss portfolio performance, including investment risk, such as the impact on the Funds of investments in particular types of securities or instruments, such as derivatives. To the extent that a Fund changes a particular investment strategy that could have a material impact on the Fund’s risk profile, the Board generally is consulted in advance with respect to such change.

Compensation
Each Trustee who is not affiliated with Invesco is compensated for his or her services according to a fee schedule that recognizes the fact that such Trustee also serves as a Trustee of other Invesco Funds. Each such Trustee receives a fee, allocated among the Invesco Funds for which he or she serves as a Trustee that consists of an annual retainer component and a meeting fee component. The Chair of the Board and of each Committee and Sub-Committee receive additional compensation for their services.
Information regarding compensation paid or accrued for each Trustee of the Trust who was not affiliated with Invesco during the year ended December 31, 2020 is found in Appendix D.
Retirement Policy
The Trustees have adopted a retirement policy that permits each Trustee to serve until December 31 of the year in which the Trustee turns 75.
Pre-Amendment Retirement Plan For Trustees
The Trustees have adopted a Retirement Plan for the Trustees who are not affiliated with the Adviser. A description of the pre-amendment Retirement Plan follows. Annual retirement benefits are available from the Funds and/or the other Invesco Funds for which a Trustee serves (each, a Covered Fund), for each Trustee who is not an employee or officer of the Adviser, who either (a) became a Trustee prior to December 1, 2008, and who has at least five years of credited service as a Trustee (including service to a predecessor fund) of a Covered Fund, or (b) was a member of the Board of Trustees of a Van Kampen Fund immediately prior to June 1, 2010 (Former Van Kampen Trustee), and has at least one year of credited service as a Trustee of a Covered Fund after June 1, 2010.
For Trustees other than Former Van Kampen Trustees, effective January 1, 2006, for retirements after December 31, 2005, the retirement benefits will equal 75% of the Trustee’s annual retainer paid to or accrued by any Covered Fund with respect to such Trustee during the twelve-month period prior to retirement, including the amount of any retainer deferred under a separate deferred compensation agreement between the Covered Fund and the Trustee. The amount of the annual retirement benefit does not include additional compensation paid for Board meeting fees or compensation paid to the Chair of the Board and the Chairs and Vice Chairs of certain Board committees, whether such amounts are paid directly to the Trustee or deferred. The annual retirement benefit is payable in quarterly installments for a number of years equal to the lesser of (i) sixteen years or (ii) the number of such Trustee’s credited years of service. If a Trustee dies prior to receiving the full amount of retirement benefits, the remaining payments will be made to the deceased Trustee’s designated beneficiary for the same length of time that the Trustee would have received the payments based on his or her service or, if the Trustee has elected, in a discounted lump sum payment. A Trustee must have attained the age of 65 (60 in the event of disability) to receive any retirement benefit. A Trustee may make an irrevocable election to commence payment of retirement benefits upon retirement from the Board before age 72; in such a case, the annual retirement benefit is subject to a reduction for early payment.
35

If the Former Van Kampen Trustee completes at least 10 years of credited service after June 1, 2010, the retirement benefit will equal 75% of the Former Van Kampen Trustee’s annual retainer paid to or accrued by any Covered Fund with respect to such Trustee during the twelve-month period prior to retirement, including the amount of any retainer deferred under a separate deferred compensation agreement between the Covered Fund and such Trustee. The amount of the annual retirement benefit does not include additional compensation paid for Board meeting fees or compensation paid to the Chair of the Board and the Chairs and Vice Chairs of certain Board committees, whether such amounts are paid directly to the Trustee or deferred. The annual retirement benefit is payable in quarterly installments for 10 years beginning after the later of the Former Van Kampen Trustee’s termination of service or attainment of age 72 (or age 60 in the event of disability or immediately in the event of death). If a Former Van Kampen Trustee dies prior to receiving the full amount of retirement benefits, the remaining payments will be made to the deceased Trustee’s designated beneficiary or, if the Trustee has elected, in a discounted lump sum payment.
If the Former Van Kampen Trustee completes less than 10 years of credited service after June 1, 2010, the retirement benefit will be payable at the applicable time described in the preceding paragraph, but will be paid in two components successively. For the period of time equal to the Former Van Kampen Trustee’s years of credited service after June 1, 2010, the first component of the annual retirement benefit will equal 75% of the compensation amount described in the preceding paragraph. Thereafter, for the period of time equal to the Former Van Kampen Trustee’s years of credited service after June 1, 2010, the second component of the annual retirement benefit will equal the excess of (x) 75% of the compensation amount described in the preceding paragraph, over (y) $68,041 plus an interest factor of 4% per year compounded annually measured from June 1, 2010 through the first day of each year for which payments under this second component are to be made. In no event, however, will the retirement benefits under the two components be made for a period of time greater than 10 years. For example, if the Former Van Kampen Trustee completes 7 years of credited service after June 1, 2010, he or she will receive 7 years of payments under the first component and thereafter 3 years of payments under the second component, and if the Former Van Kampen Trustee completes 4 years of credited service after June 1, 2010, he or she will receive 4 years of payments under the first component and thereafter 4 years of payments under the second component.
Amendment of Retirement Plan and Conversion to Defined Contribution Plan
The Trustees approved an amendment to the Retirement Plan to convert it to a defined contribution plan for active Trustees (the Amended Plan). Under the Amended Plan, the benefit amount was amended for each active Trustee to the present value of the Trustee’s existing retirement plan benefit as of December 31, 2013 (the Existing Plan Benefit) plus the present value of retirement benefits expected to be earned under the Retirement Plan through the end of the calendar year in which the Trustee attained age 75 (the Expected Future Benefit and, together with the Existing Plan Benefit, the Accrued Benefit). On the conversion date, the Covered Funds established bookkeeping accounts in the amount of their pro rata share of the Accrued Benefit, which is deemed to be invested in one or more Invesco Funds selected by the participating Trustees. Such accounts will be adjusted from time to time to reflect deemed investment earnings and losses. Each Trustee’s Accrued Benefit is not funded and, with respect to the payments of amounts held in the accounts, the participating Trustees have the status of unsecured creditors of the Covered Funds. Trustees will be paid the adjusted account balance under the Amended Plan in quarterly installments for the same period as described above.
Deferred Compensation Agreements
Four retired Trustees, as well as Messrs. LaCava, Motley, Troccoli, Vandivort, Vaughn and Wilson, Mss. Hostetler and Stern and Drs. Jones and Mathai-Davis (for purposes of this paragraph only, the Deferring Trustees) have each executed a Deferred Compensation Agreement (collectively, the Compensation Agreements). Pursuant to the Compensation Agreements, the Deferring Trustees have the option to elect to defer receipt of up to 100% of their compensation payable by the Funds, and such amounts are placed into a deferral account and deemed to be invested in one or more Invesco Funds selected by the Deferring Trustees.
36

Distributions from these deferral accounts will be paid in cash, generally in equal quarterly installments over a period of up to ten (10) years (depending on the Compensation Agreement) beginning on the date selected under the Compensation Agreement. If a Deferring Trustee dies prior to the distribution of amounts in his or her deferral account, the balance of the deferral account will be distributed to his or her designated beneficiary. The Compensation Agreements are not funded and, with respect to the payments of amounts held in the deferral accounts, the Deferring Trustees have the status of unsecured creditors of the Funds and of each other Invesco Fund from which they are deferring compensation.
Code of Ethics
Invesco, the Trust, Invesco Distributors, Inc. (Invesco Distributors) and certain of the Sub-Advisers each have adopted a Code of Ethics that applies to all Invesco Fund trustees and officers, and employees of Invesco, the Sub-Advisers and their affiliates, and governs, among other things, the personal trading activities of all such persons. Certain Sub-Advisers have adopted their own Code of Ethics. Each Code of Ethics is designed to detect and prevent improper personal trading by portfolio managers and certain other employees that could compete with or take advantage of the Fund’s portfolio transactions. Unless specifically noted, to the extent a Sub-Adviser has adopted its own Code of Ethics, each Sub-Adviser’s Code of Ethics does not materially differ from Invesco’s Code of Ethics discussed below. The Code of Ethics is intended to address conflicts of interest with the Trust that may arise from personal trading in the Invesco Funds. Personal trading, including personal trading involving securities that may be purchased or held by an Invesco Fund, is permitted under the Code of Ethics subject to certain restrictions; however, employees are required to pre-clear security transactions with the Compliance Officer or a designee and to report transactions on a regular basis.

INVESTMENT ADVISORY AND OTHER SERVICES
Investment Adviser
Invesco serves as the Funds' investment adviser. The Adviser manages the investment operations of the Funds as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of the Funds' day-to-day management. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976. Invesco Advisers, Inc. is an indirect, wholly-owned subsidiary of Invesco Ltd. Invesco Ltd. and its subsidiaries are an independent global investment management group. Certain of the directors and officers of Invesco are also executive officers of the Trust and their affiliations are shown under “Management Information” herein.
As investment adviser, Invesco supervises all aspects of the Funds' operations and provides investment advisory services to the Funds. Invesco obtains and evaluates economic, statistical and financial information to formulate and implement investment programs for the Funds. The Master Investment Advisory Agreement (Advisory Agreement) provides that, in fulfilling its responsibilities, Invesco may engage the services of other investment managers with respect to one or more of the Funds. The investment advisory services of Invesco are not exclusive and Invesco is free to render investment advisory services to others, including other investment companies.
Pursuant to an administrative services agreement with the Funds, Invesco is also responsible for furnishing to the Funds, at Invesco’s expense, the services of persons believed to be competent to perform all supervisory and administrative services required by the Funds, which in the judgment of the trustees, are necessary to conduct the business of the Funds effectively, as well as the offices, equipment and other facilities necessary for their operations. Such functions include the maintenance of each Fund’s accounts and records, and the preparation of all requisite corporate documents such as tax returns and reports to the SEC and shareholders.
The Advisory Agreement provides that each Fund will pay or cause to be paid all expenses of such Fund not assumed by Invesco, including, without limitation: brokerage commissions, taxes, legal, auditing or governmental fees, custodian, transfer and shareholder service agent costs, expenses of issue, sale, redemption, and repurchase of shares, expenses of registering and qualifying shares for sale, expenses relating to trustee and shareholder meetings, the cost of preparing and distributing reports and notices to shareholders, the fees and other expenses incurred by the Trust on behalf of each Fund in connection with membership in investment company organizations, and the cost of printing copies of prospectuses and statements of additional information distributed to the Funds' shareholders.

Invesco may from time to time waive or reduce its fee. Voluntary fee waivers or reductions may be rescinded at any time without further notice to investors. During periods of voluntary fee waivers or reductions,
38

Invesco will retain its ability to be reimbursed for such fee prior to the end of the respective fiscal year in which the voluntary fee waiver or reduction was made.
Invesco has voluntarily undertaken to waive fees to the extent necessary to assist the Funds in attempting to maintain a positive yield. There is no guarantee that a Fund will maintain a positive yield. That undertaking may be amended or rescinded at any time.
Invesco has contractually agreed through at least December 31, 2022, to waive advisory fees or reimburse expenses to the extent necessary to limit the total annual fund operating expenses (excluding (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; and (v) expenses that each Fund has incurred but did not actually pay because of an expense offset arrangement) for the following Funds’ shares:

1 The expense limitation also excludes trustees’ fees and federal registration expenses.
Acquired Fund Fees and Expenses are not operating expenses of the Funds directly, but are fees and expenses, including management fees of the investment companies in which the Funds invest.  As a result, the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement may exceed a Fund’s expense limit.
If applicable, such contractual fee waivers or reductions are set forth in the fee table to each Fund’s Prospectuses.  Unless Invesco continues the fee waiver agreement, it will terminate as indicated above.  During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit or reduce the advisory fee waivers without approval of the Board.
The management fees payable by each Fund, the amounts waived by Invesco and the net fees paid by each Fund for the last three fiscal years or periods, as applicable, ended August 31 are found in Appendix G.
Investment Sub-Advisers
Invesco has entered into a Sub-Advisory Agreement with certain affiliates to serve as sub-advisers to each Fund (each, a Sub-Adviser), pursuant to which these affiliated sub-advisers may be appointed by Invesco from time to time to provide discretionary investment management services, investment advice, and/or order execution services to the Funds. These affiliated sub-advisers, each of which is a registered investment adviser under the Advisers Act are:
Invesco Asset Management (Japan) Limited (Invesco Japan)
Invesco Asset Management Deutschland GmbH (Invesco Deutschland)
Invesco Asset Management Limited (Invesco Asset Management)
Invesco Canada Ltd. (Invesco Canada)
Invesco Hong Kong Limited (Invesco Hong Kong)
Invesco Senior Secured Management, Inc. (Invesco Senior Secured)
Invesco has also entered into a Sub-Advisory Agreement with another affiliate, Invesco Capital Management LLC (Invesco Capital), also a registered investment adviser under the Advisers Act, to provide discretionary investment management services, investment advice, and/or order execution services to Invesco Government & Agency Portfolio, Invesco Tax-Free Cash Reserve Portfolio and Invesco Treasury Obligations Portfolio.
40

Invesco has also entered into a Sub-Advisory Agreement with another affiliate, Invesco Asset Management (India) Private Limited (Invesco India), also a registered investment adviser under the Advisers Act, to provide discretionary investment management services, investment advice, and/or order execution services to Invesco Government & Agency Portfolio, Invesco Tax-Free Cash Reserve Portfolio and Invesco Treasury Obligations Portfolio.
The only fees payable to the Sub-Advisers described above under the Sub-Advisory Agreements are for providing discretionary investment management services. For such services, Invesco will pay each Sub-Adviser a fee, computed daily and paid monthly, equal to (i) 40% of the monthly compensation that Invesco receives from the Trust, multiplied by (ii) the fraction equal to the net assets of such Fund as to which such Sub-Adviser shall have provided discretionary investment management services for that month divided by the net assets of such Fund for that month. Pursuant to the Sub-Advisory Agreement, this fee is reduced to reflect contractual or voluntary fee waivers or expense limitations by Invesco, if any, in effect from time to time. In no event shall the aggregate monthly fees paid to the Sub-Advisers under the Sub-Advisory Agreement exceed 40% of the monthly compensation that Invesco receives from the Trust pursuant to its advisory agreement with the Trust, as reduced to reflect contractual or voluntary fee waivers or expense limitations by Invesco, if any.
Invesco and each Sub-Adviser are indirect wholly-owned subsidiaries of Invesco Ltd.
Marketing Support and Administrative Support Payments
Invesco, Invesco Distributors, or one of their affiliates (Invesco Affiliates) may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries that sell shares of the Invesco Funds or provide promotional and/or sales support on behalf of Invesco and Invesco Distributors with respect to the Invesco Funds. Financial intermediaries receiving marketing support payments may agree to provide a variety of services and activities that benefit Invesco and its affiliates, such as including the Invesco Funds on a preferred or select sales list or in other sales programs, providing access to the financial intermediaries’ registered representatives, providing assistance in training and education of personnel, providing marketing support, and other services. In addition, Invesco Affiliates may, from time to time, at their expense out of their own financial resources make cash payments to financial intermediaries that provide administrative services to their customers. These administrative support payments may be made for recordkeeping, sub-accounting, sub-transfer agency, shareholder processing and similar services.
Marketing and administrative support payments are in addition to any fees paid by an Invesco Fund, including Rule 12b-1 fees. Marketing and administrative support payments, whether a fixed payment or calculated as a percentage of assets attributable to a financial intermediary in a given Invesco Fund, may be different for different financial intermediaries, and shall not exceed 0.25% of the average daily net assets of all shares attributable to the financial intermediary in any Invesco Fund during a particular period. Moreover, where financial intermediaries provide services to the Invesco Funds or an Invesco Affiliate, the costs of providing the services and the package of services provided may differ. The Invesco Affiliates do not make an independent assessment of the cost of such services. A list of financial intermediaries to whom Invesco Affiliates paid marketing and/or administrative support payments during the prior calendar year is attached hereto as Appendix H. This list may not be current and changes over time.
These payments could be significant to the financial intermediaries and may create an incentive for a financial intermediary to recommend or sell shares of the Invesco Funds to its customers, thereby increasing the assets in the Invesco Funds. Please contact your financial intermediary for details about any payments they or their firm may receive in connection with the sale of Fund shares or the provision of services to the Funds.
Service Agreements
Administrative Services Agreement. Invesco and the Trust have entered into a Master Administrative Services Agreement (Administrative Services Agreement) pursuant to which Invesco may perform or arrange for the provision of certain accounting and other administrative services to each Fund which are not required
41

to be performed by Invesco under the Advisory Agreement. The Administrative Services Agreement provides that it will remain in effect and continue from year to year only if such continuance is specifically approved at least annually by the Board, including the independent trustees. Under the Administrative Services Agreement, Invesco is entitled to receive from the Funds reimbursement of its costs or such reasonable compensation. Currently, Invesco is reimbursed for the services of the Trust’s principal financial officer and her staff and any expenses related to fund accounting services.
Administrative services fees paid to Invesco by each Fund for the last three fiscal years or periods, as applicable, ended August 31 are found in Appendix I.
Other Service Providers

Other such services may be delegated or sub-contracted to third party intermediaries.  For servicing accounts holding shares of the Funds, the TA Agreement provides that the Trust, on behalf of the Funds, will pay Invesco Investment Services an asset-based fee.  The TA Agreement also provides that Invesco Investment Services is responsible for out of pocket expenses relating to the procurement of goods and services as they relate to its obligations under the TA Agreement. Invesco Investment Services may impose certain copying charges for request for copies of shareholder account statements and other historical account information older than the current year and the immediately preceding year.
Sub-Transfer Agent. Invesco Canada, 5140 Yonge Street, Suite 800, Toronto, Ontario, Canada M2N6X7, a wholly-owned, indirect subsidiary of Invesco Ltd., provides services to the Trust as a sub-transfer agent, pursuant to an agreement between Invesco Canada and Invesco Investment Services.

Custodian
The Bank of New York Mellon(the Custodian), 2 Hanson Place, Brooklyn, New York 11217-1431 is custodian of all securities and cash of the Funds.
Under its contract with the Trust, the Custodian maintains the portfolio securities of the Funds, administers the purchases and sales of portfolio securities, collects interest and dividends and other distributions made on the securities held in the portfolios of the Funds and performs other ministerial duties. These services do not include any supervisory function over management or provide any protection against any possible depreciation of assets.

In connection with the audit of the Funds' financial statements, the Funds entered into an engagement letter with PricewaterhouseCoopers LLP. The terms of the engagement
42

letter required by PricewaterhouseCoopers LLP, and agreed to by the Funds' Audit Committee, include a provision mandating the use of mediation and arbitration to resolve any controversy or claim between the parties arising out of or relating to the engagement letter or the services provided thereunder.
Counsel to the Trust. Legal matters for the Trust have been passed upon by Stradley Ronon Stevens & Young, LLP, 2005 Market Street, Suite 2600, Philadelphia, Pennsylvania 19103-7018.
BROKERAGE ALLOCATION AND OTHER PRACTICES
The Sub-Advisers have adopted compliance procedures that cover, among other items, brokerage allocation and other trading practices. If all or a portion of a Fund’s assets are managed by one or more Sub-Advisers, the decision to buy and sell securities and broker selection will be made by the Sub-Adviser for the assets it manages. Unless specifically noted, the Sub-Advisers brokerage allocation procedures do not materially differ from Invesco Advisers, Inc.’s procedures.
As discussed below, Invesco and the Sub-Advisers, unless prohibited by applicable law, may cause a Fund to pay a broker-dealer a commission for effecting a transaction that exceeds the amount another broker-dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker-dealer. Effective January 3, 2018, under the European Union’s Markets in Financial Instruments Directive (MiFID II), European Union investment advisers, including Invesco Deutschland and Invesco Asset Management, which may act as sub-adviser to certain Invesco Funds as described in such Funds' prospectuses, must pay for research from broker-dealers directly out of their own resources, rather than through client commissions.
Brokerage Transactions
Placing trades generally involves acting on portfolio manager instructions to buy or sell a specified amount of portfolio securities, including selecting one or more broker-dealers, including affiliated and third-party broker-dealers, to execute the trades, and negotiating commissions and spreads. Various Invesco Ltd. subsidiaries have created a global equity trading desk. The global equity trading desk has assigned local traders in six primary trading centers to place equity securities trades in their regions. Invesco Advisers’ Americas desk, located in Atlanta and Toronto, generally places trades of equity securities trading in North America, Canada and Latin America; the Hong Kong desk of Invesco Hong Kong (the Hong Kong Desk) generally places trades of equity securities in the Asia-Pacific markets, except Japan and China; the Japan trading desk of Invesco Japan generally places trades of equity securities in the Japanese markets; the EMEA trading desk of Invesco Asset Management Limited (the EMEA Desk) generally places trades of equity securities in European, Middle Eastern and African countries; the Australia desk, located in Sydney and Melbourne, for the execution of orders of equity securities trading in the Australian and New Zealand markets and the Taipei desk, located in Taipei, for the execution of orders of securities trading in the Chinese market. Invesco, Invesco Canada, Invesco Japan, Invesco Deutschland, Invesco Hong Kong, Invesco Capital and Invesco Asset Management use the global equity trading desk to place equity trades. Other Sub-Advisers may use the global equity trading desk in the future. The trading procedures for the global trading desks are similar in all material respects.
References in the language below to actions by Invesco or a Sub-Adviser making determinations or taking actions related to equity trading include these entities’ delegation of these determinations/actions to the Americas Desk, the Hong Kong Desk, and the EMEA Desk. Even when trading is delegated by Invesco or the Sub-Advisers to the various arms of the global equity trading desk, Invesco or the Sub-Advisers that delegate trading is responsible for oversight of this trading activity.
Invesco or the Sub-Advisers make decisions to buy and sell securities for each Fund, select broker-dealers (each, a Broker), effect the Funds' investment portfolio transactions, allocate brokerage fees in such transactions and, where applicable, negotiate commissions and spreads on transactions. Invesco’s and the Sub-Advisers’ primary consideration in effecting a security transaction is to obtain best execution, which Invesco defines as prompt and efficient execution of the transaction at the best obtainable price with payment of commissions, mark-ups or mark-downs which are reasonable in relation to the value of the brokerage
43

services provided by the Broker. While Invesco or the Sub-Advisers seek reasonably competitive commission rates, the Funds may not pay the lowest commission or spread available. See “Broker Selection” below.
Some of the securities in which the Funds invest are traded in over-the-counter (OTC) markets. Portfolio transactions in such markets may be effected on a principal basis at net prices without commissions, but which include compensation to the Broker in the form of a mark-up or mark-down, or on an agency basis, which involves the payment of negotiated brokerage commissions to the Broker, including electronic communication networks. Purchases of underwritten issues, which include initial public offerings and secondary offerings, include a commission or concession paid by the issuer (not the Funds) to the underwriter. Purchases of money market instruments may be made directly from issuers without the payment of commissions.
Historically, Invesco and the Sub-Advisers did not negotiate commission rates on stock markets outside the United States. In recent years many overseas stock markets have adopted a system of negotiated rates; however, a number of markets maintain an established schedule of minimum commission rates.
In some cases, Invesco may decide to place trades on a “blind principal bid” basis, which involves combining all trades for one or more portfolios into a single basket, and generating a description of the characteristics of the basket for provision to potential executing brokers. Based on the trade characteristics information provided by Invesco, these brokers submit bids for executing all of the required trades at a designated time for a specific commission rate. Invesco generally selects the broker with the lowest bid to execute these trades.
Commissions
There were no brokerage commissions paid by the Funds for the last three fiscal years or periods, as applicable, ended August 31.
The Funds may engage in certain principal and agency transactions with banks and their affiliates that own 5% or more of the outstanding voting securities of an Invesco Fund, provided the conditions of an exemptive order received by the Invesco Funds from the SEC are met. In addition, a Fund may purchase or sell a security from or to certain other Invesco Funds or other accounts (and may invest in the Affiliated Money Market Funds) provided the Funds follow procedures adopted by the Boards of the various Invesco Funds, including the Trust. These inter-fund transactions generally do not generate brokerage commissions but may result in custodial fees or taxes or other related expenses.
Broker Selection
Invesco’s or the Sub-Advisers’ primary consideration in selecting Brokers to execute portfolio transactions for a Fund is to obtain best execution. In selecting a Broker to execute a portfolio transaction in equity securities for a Fund, Invesco or the Sub-Advisers consider the full range and quality of a Broker’s services, including the value of research and/or brokerage services provided (if permitted by applicable law or regulation), execution capability, commission rate, and willingness to commit capital, anonymity and responsiveness. Invesco’s and the Sub-Advisers’ primary consideration when selecting a Broker to execute a portfolio transaction in fixed income securities for a Fund is the Broker’s ability to deliver or sell the relevant fixed income securities; however, Invesco and the Sub-Advisers will, if permitted by applicable law or regulation, also consider the various factors listed above. In each case, the determinative factor is not the lowest commission or spread available but whether the transaction represents the best qualitative execution for the Fund. Invesco and the Sub-Advisers will not select Brokers based upon their promotion or sale of Fund shares.
Unless prohibited by applicable law, such as MiFID II (described herein), in choosing Brokers to execute portfolio transactions for the Funds, Invesco or the Sub-Advisers may select Brokers that provide brokerage and/or research services (Soft Dollar Products) to the Funds and/or the other accounts over which Invesco and its affiliates have investment discretion. For the avoidance of doubt, European Union investment advisers, including Invesco Deutschland and Invesco Asset Management, which may act as sub-adviser to certain Invesco Funds as described in such Funds’ prospectuses, must pay for research from broker-dealers directly
44

out of their own resources, rather than through client commissions. Therefore, the use of the defined term “Sub-Advisers” throughout this section shall not be deemed to apply to those Sub-Advisers subject to the MiFID II prohibitions. Section 28(e) of the Securities Exchange Act of 1934, as amended, provides that Invesco or the Sub-Advisers, under certain circumstances, lawfully may cause an account to pay a higher commission than the lowest available. Under Section 28(e)(1), Invesco or the Sub-Advisers must make a good faith determination that the commissions paid are “reasonable in relation to the value of the brokerage and research services provided ... viewed in terms of either that particular transaction or [Invesco’s or the Sub-Advisers’] overall responsibilities with respect to the accounts as to which [it] exercises investment discretion.” The services provided by the Broker also must lawfully and appropriately assist Invesco or the Sub-Advisers in the performance of its investment decision-making responsibilities. Accordingly, a Fund may pay a Broker commissions higher than those available from another Broker in recognition of the Broker’s provision of Soft Dollar Products to Invesco or the Sub-Advisers.
Invesco and the Sub-Advisers face a potential conflict of interest when they use client trades to obtain Soft Dollar Products. This conflict exists because Invesco and the Sub-Advisers are able to use the Soft Dollar Products to manage client accounts without paying cash for the Soft Dollar Products, which reduces Invesco’s or a Sub-Adviser’s expenses to the extent that Invesco or such Sub-Adviser would have purchased such products had they not been provided by Brokers. Section 28(e) permits Invesco or the Sub-Advisers to use Soft Dollar Products for the benefit of any account it manages. Certain Invesco-managed accounts (or accounts managed by the Sub-Advisers) may generate soft dollars used to purchase Soft Dollar Products that ultimately benefit other Invesco-managed accounts (or Sub-Adviser-managed accounts), effectively cross subsidizing the other Invesco-managed accounts (or the other Sub-Adviser-managed accounts) that benefit directly from the product. Invesco or the Sub-Advisers may not use all of the Soft Dollar Products provided by Brokers through which a Fund effects securities transactions in connection with managing the Fund whose trades generated the soft dollars used to purchase such products.
Invesco presently engages in the following instances of cross-subsidization:
Fixed income funds normally do not generate soft dollar commissions to pay for Soft Dollar Products. Therefore, soft dollar commissions used to pay for Soft Dollar Products which are used to manage certain fixed income Invesco Funds are generated entirely by equity Invesco Funds and other equity client accounts managed by Invesco. In other words, certain fixed income Invesco Funds are cross-subsidized by the equity Invesco Funds in that the fixed income Invesco Funds receive the benefit of Soft Dollar Products services for which they do not pay. Similarly, other accounts managed by Invesco or certain of its affiliates may benefit from Soft Dollar Products services for which they do not pay.
Invesco and the Sub-Advisers attempt to reduce or eliminate the potential conflicts of interest concerning the use of Soft Dollar Products by directing client trades for Soft Dollar Products only if Invesco or the Sub-Adviser concludes that the Broker supplying the product is capable of providing best execution.
Certain Soft Dollar Products may be available directly from a vendor on a hard dollar basis; other Soft Dollar Products are available only through Brokers in exchange for soft dollars. Invesco and the Sub-Adviser use soft dollars to purchase two types of Soft Dollar Products:
proprietary research created by the Broker executing the trade, and
other products created by third parties that are supplied to Invesco or the Sub-Advisers through the Broker executing the trade.
Proprietary research consists primarily of traditional research reports, recommendations and similar materials produced by the in-house research staffs of broker-dealer firms. This research includes evaluations and recommendations of specific companies or industry groups, as well as analyses of general economic and market conditions and trends, market data, contacts and other related information and assistance. Invesco periodically rates the quality of proprietary research produced by various Brokers. Based on the evaluation of the quality of information that Invesco receives from each Broker, Invesco develops an estimate of each Broker’s share of Invesco clients’ commission dollars and attempts to direct trades to these firms to meet these estimates.
45

Invesco and the Sub-Advisers also use soft dollars to acquire products from third parties that are supplied to Invesco or the Sub-Advisers through Brokers executing the trades or other Brokers who “step in” to a transaction and receive a portion of the brokerage commission for the trade. Invesco or the Sub-Advisers may from time to time instruct the executing Broker to allocate or “step out” a portion of a transaction to another Broker. The Broker to which Invesco or the Sub-Advisers have “stepped out” would then settle and complete the designated portion of the transaction, and the executing Broker would settle and complete the remaining portion of the transaction that has not been “stepped out.” Each Broker may receive a commission or brokerage fee with respect to that portion of the transaction that it settles and completes.
Soft Dollar Products received from Brokers supplement Invesco’s and the Sub-Advisers’ own research (and the research of certain of its affiliates), and may include the following types of products and services:
Database Services – comprehensive databases containing current and/or historical information on companies and industries and indices. Examples include historical securities prices, earnings estimates and financial data. These services may include software tools that allow the user to search the database or to prepare value-added analyses related to the investment process (such as forecasts and models used in the portfolio management process).
Quotation/Trading/News Systems – products that provide real time market data information, such as pricing of individual securities and information on current trading, as well as a variety of news services.
Economic Data/Forecasting Tools – various macro economic forecasting tools, such as economic data or currency and political forecasts for various countries or regions.
Quantitative/Technical Analysis – software tools that assist in quantitative and technical analysis of investment data.
Fundamental/Industry Analysis – industry specific fundamental investment research.
Fixed Income Security Analysis – data and analytical tools that pertain specifically to fixed income securities. These tools assist in creating financial models, such as cash flow projections and interest rate sensitivity analyses, which are relevant to fixed income securities.
Other Specialized Tools – other specialized products, such as consulting analyses, access to industry experts, and distinct investment expertise such as forensic accounting or custom built investment-analysis software.
If Invesco or the Sub-Advisers determine that any service or product has a mixed use (i.e., it also serves functions that do not assist the investment decision-making or trading process), Invesco or the Sub-Advisers will allocate the costs of such service or product accordingly in its reasonable discretion. Invesco or the Sub-Advisers will allocate brokerage commissions to Brokers only for the portion of the service or product that Invesco or the Sub-Advisers determine assists it in the investment decision-making or trading process and will pay for the remaining value of the product or service in cash.
Outside research assistance is useful to Invesco or the Sub-Advisers because the Brokers used by Invesco or the Sub-Advisers tend to provide more in-depth analysis of a broader universe of securities and other matters than Invesco’s or the Sub-Advisers’ staff follow. In addition, such services provide Invesco or the Sub-Advisers with a diverse perspective on financial markets. Some Brokers may indicate that the provision of research services is dependent upon the generation of certain specified levels of commissions and underwriting concessions by Invesco’s or the Sub-Advisers’ clients, including the Funds. However, the Funds are not under any obligation to deal with any Broker in the execution of transactions in portfolio securities. In some cases, Soft Dollar Products are available only from the Broker providing them. In other cases, Soft Dollar Products may be obtainable from alternative sources in return for cash payments. Invesco and the Sub-Advisers believe that because Broker research supplements rather than replaces Invesco’s or the Sub-Advisers’ research, the receipt of such research tends to improve the quality of Invesco’s or the Sub-Advisers’ investment advice. The advisory fee paid by the Funds is not reduced because Invesco or the Sub-Advisers
46

receive such services. To the extent the Funds' portfolio transactions are used to obtain Soft Dollar Products, the brokerage commissions obtained by the Funds might exceed those that might otherwise have been paid.
Invesco or the Sub-Advisers may determine target levels of brokerage business with various Brokers on behalf of its clients (including the Funds) over a certain time period. Invesco determines target levels based upon the following factors, among others: (1) the execution services provided by the Broker; and (2) the research services provided by the Broker. Portfolio transactions may be effected through Brokers that recommend the Funds to their clients, or that act as agent in the purchase of a Fund’s shares for their clients, provided that Invesco or the Sub-Advisers believe such Brokers provide best execution and such transactions are executed in compliance with Invesco’s policy against using directed brokerage to compensate Brokers for promoting or selling Invesco Fund shares. Invesco and the Sub-Advisers will not enter into a binding commitment with Brokers to place trades with such Brokers involving brokerage commissions in precise amounts.
As noted above, under MiFID II, European Union investment advisers, including Invesco Deutschland and Invesco Asset Management, are not permitted to use Soft Dollar Products to pay for research from brokers but rather must pay for research out of their own profit and loss or have research costs paid by clients through research payment accounts that are funded by a specific client research charge or the research component of trade orders. Such payments for research must be unbundled from the payments for execution. As a result, Invesco Deutschland and Invesco Asset Management are restricted from using Soft Dollar Products in managing the Invesco Funds that they sub-advise.
Directed Brokerage (Research Services)
Directed brokerage (research services) commissions paid by each of the Funds during the fiscal year or period, as applicable, ended August 31 are found in Appendix J.
Affiliated Transactions
The Adviser or Sub-Adviser may place trades with Invesco Capital Markets, Inc. (ICMI), a broker-dealer with whom it is affiliated, provided the Adviser or Sub-Adviser determines that ICMI’s trade execution abilities and costs are at least comparable to those of non-affiliated brokerage firms with which the Adviser or Sub-Adviser could otherwise place similar trades. ICMI receives brokerage commissions in connection with effecting trades for the Funds and, therefore, use of ICMI presents a conflict of interest for the Adviser or Sub-Adviser. Trades placed through ICMI, including the brokerage commissions paid to ICMI, are subject to procedures adopted by the Board.
The Funds did not pay brokerage commissions on affiliated transactions for the last three fiscal years or periods, as applicable. 
Regular Brokers
Information concerning the Funds' acquisition of securities of their brokers during the last three fiscal years or periods, as applicable, ended August 31 is found in Appendix J.
Allocation of Portfolio Transactions
Invesco and the Sub-Advisers manage numerous Invesco Funds and other accounts. Some of these accounts may have investment objectives similar to the Funds. Occasionally, identical securities will be appropriate for investment by multiple Invesco Funds or other accounts. However, the position of each account in the same security and the length of time that each account may hold its investment in the same security may vary. Invesco and the Sub-Adviser will also determine the timing and amount of purchases for an account based on its cash position. If the purchase or sale of securities is consistent with the investment policies of the Fund(s) and one or more other accounts, and is considered at or about the same time, Invesco or the Sub-Adviser will allocate transactions in such securities among the Fund(s) and these accounts on a pro rata basis based on order size or in such other manner believed by Invesco to be fair and equitable. Invesco or the Sub-Adviser may combine transactions in accordance with applicable laws and regulations to
47

obtain the most favorable execution. Simultaneous transactions could, however, adversely affect a Fund’s ability to obtain or dispose of the full amount of a security which it seeks to purchase or sell.
PURCHASE, REDEMPTION, EXCHANGE AND PRICING OF SHARES
Purchase, Redemption, and Exchange of Shares
Before the initial purchase of shares, an investor must submit a completed account application either directly or through its financial intermediary, to the Funds’ transfer agent at P.O. Box 219286, Kansas City, Missouri 64121-9286. An investor may change information in his account application by submitting written changes or a new account application to his intermediary or to the Funds’ transfer agent.
Purchase and redemption orders must be received in good order. To be in good order, the investor, either directly or through his financial intermediary must give the Funds’ transfer agent all required information and documentation. Additionally, purchase payment must be made in federal funds or by check. If the intermediary fails to deliver the investor’s payment on the required settlement date, the intermediary must reimburse the Funds for any overdraft charges incurred.
The Funds’ transfer agent and Invesco Distributors may authorize agents to accept purchase and redemption orders that are in good order on behalf of the Funds. In certain cases, these authorized agents are authorized to designate other intermediaries to accept purchase and redemption orders on a Fund’s behalf. A Fund will be deemed to have received the purchase or redemption order when the Fund’s authorized agent or its designee accepts the order. The order will be priced at the net asset value next determined after the order is accepted by the Fund’s authorized agent or its designee. Orders submitted through a financial intermediary that has not received authorization to accept orders on a Fund’s behalf are priced at the Fund’s net asset value next calculated by the Fund after it receives the order from the financial intermediary and accepts it, which may not occur on the day submitted to the financial intermediary.
An investor or a financial intermediary may submit a written request to the Funds’ transfer agent for correction of transactions involving Fund shares. If the Funds’ transfer agent agrees to correct a transaction, and the correction requires a dividend adjustment, the investor or the intermediary must agree in writing to reimburse the Funds for any resulting loss.
Payment for redeemed institutional shares is normally made by Federal Reserve wire to the bank account designated in the investor’s account application, while payment for redeemed retail shares is normally made by check, but may be sent by Federal Reserve wire at the investor’s request. Any changes to wire instructions must be submitted to the Funds’ transfer agent in writing. The Funds’ transfer agent may request additional documentation. For funds that allow check writing, if you do not have a sufficient number of shares in your account to cover the amount of the check and any applicable deferred sales charge, the check will be returned and no shares will be redeemed. Because it is not possible to determine your account’s value in advance, you should not write a check for the entire value of your account or try to close your account by writing a check.
The Funds’ transfer agent may request that an intermediary maintain separate master accounts in the Funds for shares held by the intermediary (a) for its own account, for the account of other institutions and for accounts for which the intermediary acts as a fiduciary; and (b) for accounts for which the intermediary acts in some other capacity.
With regard to Funds that do not qualify as Government Money Market Funds, if a Fund’s weekly liquid assets fall below 30% of its total assets, the Board, in its discretion, may impose liquidity fees of up to 2% of the value of the shares redeemed and/or gates on redemptions. In addition, if a Fund’s weekly liquid assets fall below 10% of its total assets at the end of any business day, the Fund must impose a 1% liquidity fee on shareholder redemptions unless the Board determines that not doing so is in the best interests of the Fund. For Funds that do not qualify as Government Money Market Funds, when a fee or a gate is in place, shareholders will not be permitted to exchange into or out of a Fund.
48

The Board may, in its discretion, terminate a liquidity fee or redemption gate at any time if it believes such action to be in the best interest of the Fund and its shareholders. Also, liquidity fees and redemption gates will automatically terminate at the beginning of the next business day once a Fund’s weekly liquid assets reach at least 30% of its total assets. Redemption gates may only last up to 10 business days in any 90-day period. When a fee or a gate is in place, the Fund may elect not to permit the purchase of shares or to subject the purchase of shares to certain conditions, which may include affirmation of the purchaser’s knowledge that a fee or a gate is in effect.
The Board may, in its discretion, permanently suspend redemptions and liquidate if, among other things, a Fund, at the end of a business day, has less than 10% of its total assets invested in weekly liquid assets. The Board of the Retail and Government Money Market Funds may suspend redemptions and liquidate if the Fund’s amortized cost price per share has deviated from its market-based NAV per share, or the Board has determined such deviation is likely to occur.
You may exchange shares of Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio, Invesco Liquid Assets Portfolio, Invesco STIC Prime Portfolio, Invesco Tax-Free Cash Reserve Portfolio, or Invesco Treasury Portfolio for shares of other money market funds within the Trust and AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (except for Investor Class Shares) provided you meet the eligibility requirements of such share class, but may not exchange shares of such Funds for retail shares of other Invesco Funds.
Additional information regarding purchases and redemptions is located in each class’ prospectus, under the headings “Purchasing Shares,” “Redeeming Shares,” and “Exchanging Shares.”
Offering Price
The offering price of each Fund’s shares is the Fund’s net asset value. The Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio, Invesco Tax-Free Cash Reserve Portfolio, and Invesco Treasury Portfolio value their portfolio securities on the basis of amoratized cost, which approximates market value. This method of valuation is designed to enable a Fund to price its shares at $1.00 per share. The Funds cannot guarantee their net asset value will always remain at $1.00 per share. Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio "float" their net asset value meaning they value their portfolio securities for which market quotations are readily available at market value, and calculate their net asset values to four decimals.
Calculation of Net Asset Value (Invesco Government & Agency Portfolio, Invesco Treasury Obligations Portfolio, Invesco Tax-Free Cash Reserve Portfolio, and Invesco Treasury Portfolio)
The Board has established procedures, in accordance with Rule 2a-7 under the 1940 Act, designed to stabilize each Fund’s net asset value per share at $1.00, to the extent reasonably possible. Such procedures include daily calculation of the extent of the deviation, if any, of the current net asset value per share using available market quotations from the fund's amortized cost price per share, and the periodic review by the Trustees of the amount of such deviation. The reviews are used to determine whether net asset value, calculated by using available market quotations, deviates from $1.00 per share and, if so, whether such deviation may result in material dilution or is otherwise unfair to investors or existing shareholders. In the event the trustees determine that a material deviation exists, they intend to take such corrective action as they deem necessary and appropriate. Such actions may include selling portfolio securities prior to maturity in order to realize capital gains or losses or to shorten average portfolio maturity, withholding dividends, redeeming shares in kind, or establishing a net asset value per share by using available market quotations. When available market quotations are used to establish the market-based net asset value, the net asset value could possibly be more or less than $1.00 per share.
Under the amortized cost method, each investment is valued at its cost and thereafter any discount or premium is amortized on a constant basis to maturity. Although this method provides certainty of valuation, it may result in periods in which the amortized cost value of the Funds’ investments is high or lower than the price that would be received if the investments were sold.
49

Calculation of Net Asset Value (Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio)
Invesco Liquid Assets Portfolio determines its net asset value per share at 8:00 a.m., 12:00 p.m., and 3:00 p.m. Eastern Time on each business day of the Fund. Invesco STIC Prime Portfolio determines its net asset value per share at 3:00 p.m. Eastern Time. In the event the Fund closes early on a business day, each Fund will calculate its net asset value as of the time of such closing. For Funds with multiple net asset value strike times, in the event the Fund closes early, the Fund’s last net asset value strike time for such day will be the strike time immediately prior to the Fund’s early close. The Funds determine net asset value per share by dividing the value of an Invesco Fund’s securities, cash and other assets (including interest accrued but not collected) attributable to a particular class, less all its liabilities (including accrued expenses and dividends payable) attributable to that class, by the total number of shares outstanding of that class. Determination of a Fund’s net asset value per share is made in accordance with generally accepted accounting principles. The net asset value for shareholder transactions may be different than the net asset value reported in the Fund’s financial statement due to adjustments required by generally accepted accounting principles made to the net asset value of the Fund at period end.
Debt securities (including convertible bonds) and unlisted equities are fair valued using an evaluated quote provided by an independent pricing vendor. Evaluated quotes provided by the pricing vendor may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution size, trading in similar groups of securities, developments related to special securities, dividend rate, yield, quality, coupon rate, maturity, type of issue, individual trading characteristics and other market data. Securities for which market prices are not provided by any of the above methods may be valued based upon quotes furnished by independent sources and are valued at the last bid price in the case of equity securities and Corporate Loans and in the case of debt obligations (excluding Corporate Loans), the mean between the last bid and ask prices. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data. Investments in open-end and closed-end registered investment companies that do not trade on an exchange are valued at the end of day net asset value per share.
Generally, trading in corporate bonds, U.S. Government Securities and money market instruments is substantially completed each day prior to the close of the customary trading session of the New York Stock Exchange (NYSE). The values of such securities used in computing the net asset value of an Invesco Fund's shares are the valuation time(s) for the particular Fund. Occasionally, events affecting the values of such securities may occur between the times at which such values are determined and the close of the customary trading session of the NYSE. If the Adviser believes a development/event has actually caused a closing price to no longer reflect current market value, the closing price may be adjusted to reflect the fair value of the affected security as of the close of the NYSE as determined in good faith using procedures approved by the Board.
Foreign securities are converted into U.S. dollar amounts using exchange rates as of the valuation time(s) for the particular Fund. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the valuation time(s) for the particular Fund, events occur that are significant and may make the closing price unreliable, the Invesco Fund may fair value the security. If an issuer specific event has occurred that the Adviser determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value in good faith using procedures approved by the Board. Adjustments to closing prices to reflect fair value may also be based on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where the Adviser believes, at the approved degree of certainty, that the price is not reflective of current market value, the Adviser will use the indication of fair value from the pricing vendor to determine the fair value of the security. The pricing vendor, pricing methodology or degree of
50

certainty may change from time to time. Multiple factors may be considered by the pricing vendor in determining adjustments to reflect fair value and may include information relating to sector indices, American Depositary Receipts, domestic and foreign index futures, and exchange-traded funds.
Invesco Fund securities primarily traded in foreign markets may be traded in such markets on days that are not business days of the Invesco Fund. Because the net asset value per share of each Invesco Fund is determined only on business days of the Invesco Fund, the value of the portfolio securities of an Invesco Fund that invests in foreign securities may change on days when an investor cannot exchange or redeem shares of the Invesco Fund.
Securities for which market quotations are not available or are unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust's officers in accordance with procedures approved by the Board of Trustees. Issuer specific events, market trends, bid/ask quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security's fair value.
Redemptions in Kind
The Funds do not intend to redeem shares representing an interest in the Funds in kind (i.e., by distributing its portfolio securities).
Although the Invesco Funds generally intend to pay redemption proceeds solely in cash, the Invesco Funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind). For instance, an Invesco Fund may make a redemption in kind if a cash redemption would disrupt its operations or performance. Securities that will be delivered as payment in redemptions in kind will be valued using the same methodologies that the Invesco Fund typically utilizes in valuing such securities. Shareholders receiving such securities are likely to incur transaction and brokerage costs on their subsequent sales of such securities, and the securities may increase or decrease in value until the shareholder sells them. The Trust, on behalf of the Invesco Funds, made an election under Rule 18f-1 under the 1940 Act (a Rule 18f-1 Election) and therefore, the Trust, on behalf of an Invesco Fund, is obligated to redeem for cash all shares presented to such Invesco Fund for redemption by any one shareholder in an amount up to the lesser of $250,000 or 1% of that Invesco Fund's net assets in any 90-day period. The Rule 18f-1 Election is irrevocable while Rule 18f-1 under the 1940 Act is in effect unless the SEC by order permits withdrawal of such Rule 18f-1 Election.
Backup Withholding
Accounts submitted without a correct, certified taxpayer identification number (TIN) or, alternatively, a correctly completed and currently effective IRS Form W-8 (for non-resident aliens) or Form W-9 (for U.S. persons including resident aliens) accompanying the registration information generally will be subject to backup withholding.
Each Invesco Fund, and other payers, generally must withhold 24% of reportable dividends (whether paid in cash or reinvested in additional Invesco Fund shares), including exempt-interest dividends, in the case of any shareholder who fails to provide the Invesco Funds with a TIN and a certification that he is not subject to backup withholding.
An investor is subject to backup withholding if:
1. The investor fails to furnish a correct TIN to the Invesco Fund;
2. the IRS notifies the Invesco Fund that the investor furnished an incorrect TIN;
3. the investor or the Invesco Fund is notified by the IRS that the investor is subject to backup withholding because the investor failed to report all of the interest and dividends on such investor’s tax return (for reportable interest and dividends only);
4. the investor fails to certify to the Invesco Fund that the investor is not subject to backup withholding under (3) above (for reportable interest and dividend accounts opened after 1983 only); or
51

5. the investor does not certify his TIN. This applies only to non-exempt mutual fund accounts opened after 1983.
Interest and dividend payments are subject to backup withholding in all five situations discussed above. Redemption proceeds are subject to backup withholding only if (1), (2) or (5) above applies.
Certain payees and payments are exempt from backup withholding and information reporting. Invesco or the Transfer Agent will not provide Form 1099 to those payees.
Investors should contact the IRS if they have any questions concerning withholding.
IRS Penalties. Investors who do not supply the Invesco Funds with a correct TIN will be subject to a $50 penalty imposed by the IRS unless such failure is due to reasonable cause and not willful neglect. If an investor falsifies information on this form or makes any other false statement resulting in no backup withholding on an account which should be subject to backup withholding, such investor may be subject to a $500 penalty imposed by the IRS and to certain criminal penalties including fines and/or imprisonment.
Nonresident Aliens. Nonresident alien individuals and foreign entities with a valid Form W-8 are not subject to the backup withholding previously discussed. The Form W-8 generally remains in effect for a period starting on the date the Form is signed and ending on the last day of the third succeeding calendar year. Such shareholders may, however, be subject to federal income tax withholding at a 30% rate on ordinary income dividends and other distributions. Under applicable treaty law, residents of treaty countries may qualify for a reduced rate of withholding or a withholding exemption. Nonresident alien individuals and some foreign entities failing to provide a valid Form W-8 may be subject to backup withholding and Form 1099 reporting.
DIVIDENDS, DISTRIBUTIONS AND TAX MATTERS
Dividends and Distributions
The following discussion of dividends and distributions should be read in connection with the applicable sections in the Prospectus.
All dividends and distributions will be automatically reinvested in additional shares of the same class of a Fund unless the shareholder has requested in writing to receive such dividends and distributions in cash or that they be invested in shares of another Invesco Fund, subject to the terms and conditions set forth in the Prospectus under the caption “Purchasing Shares - Automatic Dividend and Distribution Investment.” Such dividends and distributions will be reinvested at the net asset value per share determined on the ex-dividend date.
The Fund calculates income dividends and capital gain distributions the same way for each class. The amount of any income dividends per share will differ, however, generally due to any differences in the distribution and service (Rule 12b-1) fees applicable to the classes, as well as any other expenses attributable to a particular class (Class Expenses). Class Expenses, including distribution plan expenses, must be allocated to the class for which they are incurred consistent with applicable legal principles under the 1940 Act.
In the eventa Fund (other than Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, both of which are “floating” NAV Funds), incurs or anticipates any unusual expense, loss or depreciation in the value of a portfolio investment that would adversely affect the net asset value per share of the Fund or the net income per share of a class of the Fund for a particular period, the Board would at that time consider whether to adhere to the present dividend policy described above or to revise it in light of then prevailing circumstances. For example, if the net asset value per share of the Fund was reduced, or was anticipated to be reduced below $1.00, the Board might suspend further dividend payments on shares of the Fund until the net asset value returns to $1.00. Thus, such expense, loss or depreciation might result in a shareholder receiving no dividends for the period during which it held shares of the Fund and/or its receiving upon redemption a price per share lower than that which it paid.
52

Tax Matters
The following is a summary of certain additional tax considerations generally affecting the Fund and its shareholders that are not described in the Prospectus. No attempt is made to present a detailed explanation of the tax treatment of the Fund or its shareholders, and the discussion here and in the Prospectus is not intended as a substitute for careful tax planning.
This “Tax Matters” section is based on the Code and applicable regulations in effect on the date of this SAI. Future legislative, regulatory or administrative changes, including provisions of current law that sunset and thereafter no longer apply, or court decisions may significantly change the tax rules applicable to the Fund and its shareholders. Any of these changes or court decisions may have a retroactive effect.
This is for general information only and not tax advice. All investors should consult their own tax advisors as to the federal, state, local and foreign tax provisions applicable to them.
Taxation of the Fund. The Fund has elected and intends to qualify (or, if newly organized, intends to elect and qualify) each year as a “regulated investment company” (sometimes referred to as a regulated investment company, RIC or fund) under Subchapter M of the Code. If the Fund qualifies, the Fund will not be subject to federal income tax on the portion of its investment company taxable income (i.e., generally, taxable interest, dividends, net short-term capital gains and other taxable ordinary income net of expenses without regard to the deduction for dividends paid) and net capital gain (i.e., the excess of net long-term capital gains over net short-term capital losses) that it distributes to shareholders.
Qualification as a regulated investment company. In order to qualify for treatment as a regulated investment company, the Fund must satisfy the following requirements:
Distribution Requirement – the Fund must distribute an amount equal to the sum of at least 90% of its investment company taxable income and 90% of its net tax-exempt income, if any, for the tax year (certain distributions made by the Fund after the close of its tax year are considered distributions attributable to the previous tax year for purposes of satisfying this requirement).
Income Requirement – the Fund must derive at least 90% of its gross income from dividends, interest, certain payments with respect to securities loans, and gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including, but not limited to, gains from options, futures or forward contracts) derived from its business of investing in such stock, securities or currencies and net income derived from qualified publicly traded partnerships (QPTPs).
Asset Diversification Test – the Fund must satisfy the following asset diversification test at the close of each quarter of the Fund’s tax year: (1) at least 50% of the value of the Fund’s assets must consist of cash and cash items, U.S. Government Securities, securities of other regulated investment companies, and securities of other issuers (as to which the Fund has not invested more than 5% of the value of the Fund’s total assets in securities of an issuer and as to which the Fund does not hold more than 10% of the outstanding voting securities of the issuer); and (2) no more than 25% of the value of the Fund’s total assets may be invested in the securities of any one issuer (other than U.S. Government Securities or securities of other regulated investment companies) or of two or more issuers which the Fund controls and which are engaged in the same or similar trades or businesses, or, collectively, in the securities of QPTPs.
In some circumstances, the character and timing of income realized by the Fund for purposes of the Income Requirement or the identification of the issuer for purposes of the Asset Diversification Test is uncertain under current law with respect to a particular investment, and an adverse determination or future guidance by the IRS with respect to such type of investment may adversely affect the Fund’s ability to satisfy these requirements. See “Tax Treatment of Portfolio Transactions” with respect to the application of these requirements to certain types of investments. In other circumstances, the Fund may be required to sell portfolio holdings in order to meet the Income Requirement, Distribution Requirement, or Asset Diversification Test, which may have a negative impact on the Fund’s income and performance. In lieu of potential
53

disqualification, the Fund is permitted to pay a tax for certain failures to satisfy the Asset Diversification Test or Income Requirement, which, in general, are limited to those due to reasonable cause and not willful neglect.
The Fund may use “equalization accounting” (in lieu of making some cash distributions) in determining the portion of its income and gains that has been distributed. If the Fund uses equalization accounting, it will allocate a portion of its undistributed investment company taxable income and net capital gain to redemptions of Fund shares and will correspondingly reduce the amount of such income and gains that it distributes in cash. However, the Fund intends to make cash distributions for each taxable year in an aggregate amount that is sufficient to satisfy the Distribution Requirement without taking into account its use of equalization accounting. If the IRS determines that the Fund’s allocation is improper and that the Fund has under-distributed its income and gain for any taxable year, the Fund may be liable for federal income and/or excise tax.
If for any taxable year the Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain) would be subject to tax at the corporate income tax rate without any deduction for dividends paid to shareholders, and the dividends would be taxable to the shareholders as ordinary income (or possibly as qualified dividend income) to the extent of the Fund’s current and accumulated earnings and profits. Failure to qualify as a regulated investment company thus would have a negative impact on the Fund’s income and performance. Subject to savings provisions for certain inadvertent failures to satisfy the Income Requirement or Asset Diversification Test which, in general, are limited to those due to reasonable cause and not willful neglect, it is possible that the Fund will not qualify as a regulated investment company in any given tax year. Even if such savings provisions apply, the Fund may be subject to a monetary sanction of $50,000 or more. Moreover, the Board reserves the right not to maintain the qualification of the Fund as a regulated investment company if it determines such a course of action to be beneficial to shareholders.
Capital loss carryovers. The capital losses of the Fund, if any, do not flow through to shareholders. Rather, the Fund may use its capital losses, subject to applicable limitations, to offset its capital gains without being required to pay taxes on or distribute to shareholders such gains that are offset by the losses. If the Fund has a “net capital loss” (that is, capital losses in excess of capital gains), the excess (if any) of the Fund’s net short-term capital losses over its net long-term capital gains is treated as a short-term capital loss arising on the first day of the Fund’s next taxable year, and the excess (if any) of the Fund’s net long-term capital losses over its net short-term capital gains is treated as a long-term capital loss arising on the first day of the Fund’s next taxable year. Any such net capital losses of the Fund that are not used to offset capital gains may be carried forward indefinitely to reduce any future capital gains realized by the Fund in succeeding taxable years. The amount of capital losses that can be carried forward and used in any single year is subject to an annual limitation if there is a more than 50% “change in ownership” of the Fund. An ownership change generally results when shareholders owning 5% or more of the Fund increase their aggregate holdings by more than 50% over a three-year look-back period. An ownership change could result in capital loss carryovers being used at a slower rate thereby reducing the Fund’s ability to offset capital gains with those losses. An increase in the amount of taxable gains distributed to the Fund’s shareholders could result from an ownership change. The Fund undertakes no obligation to avoid or prevent an ownership change, which can occur in the normal course of shareholder purchases and redemptions or as a result of engaging in a tax-free reorganization with another fund. Moreover, because of circumstances beyond the Fund’s control, there can be no assurance that the Fund will not experience, or has not already experienced, an ownership change.
Deferral of late year losses. The Fund may elect to treat part or all of any “qualified late year loss” as if it had been incurred in the succeeding taxable year in determining the Fund’s taxable income, net capital gain, net short-term capital gain, and earnings and profits. The effect of this election is to treat any such “qualified late year loss” as if it had been incurred in the succeeding taxable year, which may change the timing, amount, or characterization of Fund distributions (see “Taxation of Fund Distributions — Capital gain dividends” below). A “qualified late year loss” includes:
54

(i) any net capital loss incurred after October 31 of the current taxable year, or, if there is no such loss, any net long-term capital loss or any net short-term capital loss incurred after October 31 of the current taxable year (post-October capital losses); and
(ii) the sum of (1) the excess, if any, of (a) specified losses incurred after October 31 of the current taxable year, over (b) specified gains incurred after October 31 of the current taxable year and (2) the excess, if any, of (a) ordinary losses incurred after December 31 of the current taxable year, over (b) the ordinary income incurred after December 31 of the current taxable year.
The terms “specified losses” and “specified gains” mean ordinary losses and gains from the sale, exchange, or other disposition of property (including the termination of a position with respect to such property), foreign currency losses and gains, and losses and gains resulting from holding stock in a passive foreign investment company (PFIC) for which a mark-to-market election is in effect. The terms “ordinary losses” and “ordinary income” mean other ordinary losses and income that are not described in the preceding sentence.
Special rules apply to a fund with a fiscal year ending in November or December that elects to use its taxable year for determining its capital gain net income for excise tax purposes.
Federal excise tax. To avoid a 4% non-deductible excise tax, the Fund must distribute by December 31 of each year an amount equal to at least: (1) 98% of its ordinary income for the calendar year, (2) 98.2% of capital gain net income (the excess of the gains from sales or exchanges of capital assets over the losses from such sales or exchanges) for the one-year period ended on October 31 of such calendar year (or, at the election of a regulated investment company having a taxable year ending November 30 or December 31, for its taxable year), and (3) any prior year undistributed ordinary income and capital gain net income. The Fund may elect to defer to the following year any net ordinary loss incurred for the portion of the calendar year which is after the beginning of the Fund’s taxable year. Also, the Fund will defer any “specified gain” or “specified loss” which would be properly taken into account for the portion of the calendar after October 31. Any net ordinary loss, specified gain, or specified loss deferred shall be treated as arising on January 1 of the following calendar year. Generally, the Fund may make sufficient distributions to avoid liability for federal income and excise tax, but can give no assurances that all or a portion of such liability will be avoided. In addition, under certain circumstances temporary timing or permanent differences in the realization of income and expense for book and tax purposes can result in the Fund having to pay an excise tax.
Foreign income tax. Investment income received by the Fund from sources within foreign countries may be subject to foreign income tax withheld at the source, and the amount of tax withheld generally will be treated as an expense of the Fund. The United States has entered into tax treaties with many foreign countries that entitle the Fund to a reduced rate of, or exemption from, tax on such income. Some countries require the filing of a tax reclaim or other forms to receive the benefit of the reduced tax rate; whether or when the Fund will receive the tax reclaim is within the control of the individual country. Information required on these forms may not be available such as shareholder information; therefore, the Fund may not receive the reduced treaty rates or potential reclaims. Other countries have conflicting and changing instructions and restrictive timing requirements which may cause the Fund not to receive the reduced treaty rates or potential reclaims. Other countries may subject capital gains realized by the Fund on sale or disposition of securities of that country to taxation. These and other factors may make it difficult for the Fund to determine in advance the effective rate of tax on its investments in certain countries. Under certain circumstances, the Fund may elect to pass-through certain eligible foreign income taxes paid by the Fund to shareholders, although it reserves the right not to do so. If the Fund makes such an election and obtains a refund of foreign taxes paid by the Fund in a prior year, the Fund may be eligible to reduce the amount of foreign taxes reported by the Fund to its shareholders, generally by the amount of the foreign taxes refunded, for the year in which the refund is received. Certain foreign taxes imposed on the Fund's investments, such as a foreign financial transaction tax, may not be creditable against U.S. income tax liability or eligible for pass through by the Fund to its shareholders.
As a result of several court cases, in certain countries across the European Union, the Fund may have filed additional tax reclaims for previously withheld taxes on dividends earned in those countries ("EU
55

reclaims"). For U.S. income tax purposes, EU reclaims plus interest received by the Fund, if any, reduce the amount of foreign taxes Fund shareholders can use as tax deductions or credits on their income tax returns, if any. Any interest received that offsets such foreign taxes is required to be reported to the shareholder as additional dividend income from the Fund and included in the shareholder's gross income. In the event that EU reclaims received by the Fund during a fiscal year exceed foreign withholding taxes paid by the Fund, and the Fund previously passed through to its shareholders foreign taxes incurred by the Fund to be used as a credit or deduction on a shareholder's income tax return, the Fund will enter into a closing agreement with the IRS in order to pay the associated tax liability on behalf of the Fund's shareholders.
Liquidity Fees. There is some degree of uncertainty with respect to the tax treatment of liquidity fees received by a Fund, and such tax treatment may be the subject of future IRS guidance. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.
Taxation of Fund Distributions (All Funds Except Invesco Tax-Free Cash Reserve Portfolio). The Fund anticipates distributing substantially all of its investment company taxable income and net capital gain for each taxable year. Distributions by the Fund will be treated in the manner described below regardless of whether such distributions are paid in cash or reinvested in additional shares of the Fund (or of another Fund). The Fund will send you information annually as to the federal income tax consequences of distributions made (or deemed made) during the year.
Distributions of ordinary income. The Fund receives income generally in the form of interest on its investments. The Fund may also recognize ordinary income from other sources, including, but not limited to, certain gains on foreign currency-related transactions. The Fund also may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. This income, less expenses incurred in the operation of the Fund, constitutes the Fund’s net investment income from which dividends may be paid to you. If you are a taxable investor, distributions of net investment income generally are taxable as ordinary income to the extent of the Fund’s earnings and profits. In the case of a Fund whose strategy includes investing in stocks of corporations, a portion of the income dividends paid to you may be qualified dividends eligible to be taxed at reduced rates.
Capital gain dividends. Taxes on distributions of capital gains are determined by how long the Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. In general, the Fund will recognize long-term capital gain or loss on the sale or other disposition of assets it has owned for more than one year, and short-term capital gain or loss on investments it has owned for one year or less. Distributions of net capital gain (the excess of net long-term capital gain over net short-term capital loss) that are properly reported by the Fund to shareholders as capital gain dividends generally will be taxable to a shareholder receiving such distributions as long-term capital gain. Long-term capital gain rates applicable to individuals are 0%, 15%, 20% or 25% depending on the nature of the capital gain and the individual’s taxable income. Distributions of net short-term capital gains for a taxable year in excess of net long-term capital losses for such taxable year generally will be taxable to a shareholder receiving such distributions as ordinary income. The Fund does not expect to realize any long-term capital gains and losses.
Qualified dividend income for individuals. Because the income of the Fund primarily is derived from investments earning interest rather than dividend income, generally none of the Fund’s income dividends will be qualified dividend income eligible for taxation at capital gain rates.
Corporate dividends-received deduction. Because the income of the Fund primarily is derived from investments earning interest rather than dividend income, generally none of its income dividends will be eligible for the corporate dividends-received deduction.
Maintaining a $1.00 share price. .Because the shares in the Funds, other than Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, are offered and redeemed at a constant net asset value of $1.00 per share, gains and losses on the sale of portfolio securities and unrealized appreciation or depreciation in the value of these securities may require the Fund to adjust its dividends to maintain its $1.00 share price. This procedure may result in under- or over-distributions by the Fund of its net investment income. This in turn may result in return of capital distributions, the effect of which is described in the following paragraph.
56

Return of capital distributions. Distributions by the Fund that are not paid from earnings and profits will be treated as a return of capital to the extent of (and in reduction of) the shareholder’s tax basis in his shares; any excess will be treated as gain from the sale of his shares. Thus, the portion of a distribution that constitutes a return of capital will decrease the shareholder’s tax basis in his Fund shares (but not below zero), and will result in an increase in the amount of gain (or decrease in the amount of loss) that will be recognized by the shareholder for tax purposes on the later sale of such Fund shares. Return of capital distributions can occur for a number of reasons including, among others, the Fund over-estimates the income to be received from certain investments.
Tax credit bonds. If the Fund holds, directly or indirectly, one or more “tax credit bonds” (including build America bonds, clean renewable energy bonds and qualified tax credit bonds) on one or more applicable dates during a taxable year, the Fund may elect to permit its shareholders to claim a tax credit on their income tax returns equal to each shareholder’s proportionate share of tax credits from the applicable bonds that otherwise would be allowed to the Fund. In such a case, shareholders must include in gross income (as interest) their proportionate share of the income attributable to their proportionate share of those offsetting tax credits. A shareholder’s ability to claim a tax credit associated with one or more tax credit bonds may be subject to certain limitations imposed by the Code. (Under the Tax Cuts and Jobs Act, build America bonds, clean renewable energy bonds and certain other qualified bonds may no longer be issued after December 31, 2017.) Even if the Fund is eligible to pass-through tax credits to shareholders, the Fund may choose not to do so.
U.S. Government interest. Income earned on certain U.S. Government obligations is exempt from state and local personal income taxes if earned directly by you. States also grant tax-free status to dividends paid to you from interest earned on direct obligations of the U.S. Government, subject in some states to minimum investment or reporting requirements that must be met by the Fund. Income on investments by the Fund in certain other obligations, such as repurchase agreements collateralized by U.S. Government obligations, commercial paper and federal agency-backed obligations (e.g., GNMA or FNMA obligations), generally does not qualify for tax-free treatment. The rules on exclusion of this income are different for corporations.
Dividends declared in December and paid in January. Ordinarily, shareholders are required to take distributions by the Fund into account in the year in which the distributions are made. However, dividends declared in October, November or December of any year and payable to shareholders of record on a specified date in such a month will be deemed to have been received by the shareholders (and made by the Fund) on December 31 of such calendar year if such dividends are actually paid in January of the following year. Shareholders will be advised annually as to the U.S. federal income tax consequences of distributions made (or deemed made) during the year in accordance with the guidance that has been provided by the IRS.
Medicare tax. A 3.8% Medicare tax is imposed on net investment income earned by certain individuals, estates and trusts. “Net investment income,” for these purposes, means investment income, including ordinary dividends and capital gain distributions received from the Fund and net gains from redemptions or other taxable dispositions of Fund shares, reduced by the deductions properly allocable to such income.  In the case of an individual, the tax will be imposed on the lesser of (1) the shareholder’s net investment income or (2) the amount by which the shareholder’s modified adjusted gross income exceeds $250,000 (if the shareholder is married and filing jointly or a surviving spouse), $125,000 (if the shareholder is married and filing separately) or $200,000 (in any other case).  This Medicare tax, if applicable, is reported by you on, and paid with, your federal income tax return. Net investment income does not include exempt-interest dividends.
Taxation of Fund Distributions(Invesco Tax-Free Cash Reserve Portfolio Only). The Fund intends to qualify each year to pay exempt-interest dividends by satisfying the requirement that at the close of each quarter of the Fund’s taxable year at least 50% of the Fund’s total assets consists of Municipal Securities, which are exempt from federal income tax.
Exempt-interest dividends. Distributions from the Fund will constitute exempt-interest dividends to the extent of the Fund’s tax-exempt interest income (net of allocable expenses and amortized bond premium). Exempt-interest dividends distributed to shareholders of the Fund are excluded from gross income for federal income tax purposes. However, shareholders required to file a federal income tax return will be required to
57

report the receipt of exempt-interest dividends on their returns. Moreover, while exempt-interest dividends are excluded from gross income for federal income tax purposes, they may be subject to alternative minimum tax (AMT) in certain circumstances and may have other collateral tax consequences as discussed below.
Distribution of ordinary income and capital gains. Any gain or loss from the sale or other disposition of a tax-exempt security generally is treated as either long-term or short-term capital gain or loss, depending upon its holding period, and is fully taxable as described in “Taxation of Fund Distributions — Capital gain dividends.” However, gain recognized from the sale or other disposition of a Municipal Security purchased after April 30, 1993, will be treated as ordinary income to the extent of the accrued market discount on such security. Distributions by the Fund of ordinary income and capital gains will be taxable to shareholders as discussed under “Taxation of Fund Distributions — Distributions of ordinary income.”
Alternative minimum tax private activity bonds. AMT is imposed in addition to, but only to the extent it exceeds, the regular tax and is computed at a maximum rate of 28% for non-corporate taxpayers on the excess of the taxpayer’s alternative minimum taxable income (AMTI) over an exemption amount. Exempt-interest dividends derived from certain “private activity” Municipal Securities issued after August 7, 1986, generally will constitute an item of tax preference includable in AMTI for non-corporate taxpayers. However, tax-exempt interest on private activity bonds issued in 2009 and 2010 is not an item of tax preference for purposes of the AMT. Consistent with its stated investment objective, the Invesco Tax-Free Cash Reserve Portfolio intends to limit its investments in private activity bonds subject to the AMT to no more than 20% of its total assets in any given year.
Effect on taxation of social security benefits; denial of interest deduction; “substantial users. Exempt-interest dividends must be taken into account in computing the portion, if any, of social security or railroad retirement benefits that must be included in an individual shareholder’s gross income subject to federal income tax. Further, a shareholder of the Fund is denied a deduction for interest on indebtedness incurred or continued to purchase or carry shares of the Fund. Moreover, a shareholder who is (or is related to) a “substantial user” of a facility financed by industrial development bonds held by the Fund will likely be subject to tax on dividends paid by the Fund that are derived from interest on such bonds. Receipt of exempt-interest dividends may result in other collateral federal income tax consequences to certain taxpayers, including financial institutions, property and casualty insurance companies and foreign corporations engaged in a trade or business in the United States.
Exemption from state tax. To the extent that exempt-interest dividends are derived from interest on obligations of a state or its political subdivisions or from interest on qualifying U.S. territorial obligations (including qualifying obligations of Puerto Rico, the U.S. Virgin Islands, and Guam), they also may be exempt from that state’s personal income taxes. Most states, however, do not grant tax-free treatment to interest on state and municipal securities of other states.
Failure of a Municipal Security to qualify to pay exempt-interest. Failure of the issuer of a tax-exempt security to comply with certain legal or contractual requirements relating to a Municipal Security could cause interest on the Municipal Security, as well as Fund distributions derived from this interest, to become taxable, perhaps retroactively to the date the Municipal Security was issued. In such a case, the Fund may be required to report to the IRS and send to shareholders amended Forms 1099 for a prior taxable year in order to report additional taxable income. This in turn could require shareholders to file amended federal and state income tax returns for such prior year to report and pay tax and interest on their pro rata share of the additional amount of taxable income.
Sale or Redemption of Fund Shares. A shareholder will recognize gain or loss on the sale or redemption of shares of the Fund in an amount equal to the difference between the proceeds of the sale or redemption and the shareholder’s adjusted tax basis in the shares. Because the shares in the Funds, other than Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio, are offered and redeemed at a constant net asset value of $1.00 per share, a shareholder generally will recognize neither gain nor loss on a redemption of shares (unless the shareholder incurs a liquidity fee on such redemption). Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio each round their current net asset value per share to a
58

minimum of the fourth decimal place, therefore, investors will have gain or loss on sale or exchange of shares of those Funds calculated by subtracting from the gross proceeds received from the sale or exchange your cost basis.
Shareholders may elect to adopt a simplified “NAV method” for computing gains and losses from taxable sales, exchanges or redemptions of Fund shares. Under the NAV method, rather than computing gain or loss separately for each taxable disposition of Fund shares as described above, a shareholder would determine gain or loss based on the change in the aggregate value of the shareholder’s Fund shares during a computation period (which could be the shareholder’s taxable year or certain shorter periods), reduced by the shareholder’s net investment (purchases minus taxable sales, exchanges, or redemptions or exchanges) in those Fund shares during that period. Under the NAV method, if a shareholder holds the shares as a capital asset, any resulting net gain or loss would be treated as short-term capital gain or loss.
Tax basis information. Cost basis reporting is not required for shareholders investing in a money market fund operating under Rule 2a-7 under the 1940 Act.
Wash sale rule. All or a portion of any loss so realized on the sale or redemption of shares in the Funds (other than Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio) may be deferred under the wash sale rules if the shareholder purchases other shares of the same Fund within 30 days before or after the sale or redemption and the shareholder does not elect to adopt the NAV method. A shareholder that realizes a loss on the redemption of shares in Invesco Liquid Assets Portfolio and Invesco STIC Prime Portfolio and purchases other shares of the same Fund within 30 days before or after the redemption is not subject to the wash sale rules and may recognize such loss in the year realized if the shareholder does not elect to adopt the NAV method.
Tax Treatment of Portfolio Transactions. Set forth below is a general description of the tax treatment of certain types of securities, investment techniques and transactions that may apply to a fund. This section should be read in conjunction with the discussion under “Description of the Funds and their Investments and Risks — Investment Strategies and Risks” for a detailed description of the various types of securities and investment techniques that apply to the Fund.
In general. In general, gain or loss recognized by a fund on the sale or other disposition of portfolio investments will be a capital gain or loss. Such capital gain and loss may be long-term or short-term depending, in general, upon the length of time a particular investment position is maintained and, in some cases, upon the nature of the transaction. Property held for more than one year generally will be eligible for long-term capital gain or loss treatment. The application of certain rules described below may serve to alter the manner in which the holding period for a security is determined or may otherwise affect the characterization as long-term or short-term, and also the timing of the realization and/or character, of certain gains or losses.
Certain fixed-income investments. Gain recognized on the disposition of a debt obligation purchased by a fund at a market discount (generally, at a price less than its principal amount) will be treated as ordinary income to the extent of the portion of the market discount that accrued during the period of time the fund held the debt obligation unless the fund made a current inclusion election to accrue market discount into income as it accrues. If a fund purchases a debt obligation (such as a zero coupon security or pay-in-kind security) that was originally issued at a discount, the fund generally is required to include in gross income each year the portion of the original issue discount that accrues during such year. Therefore, a fund’s investment in such securities may cause the fund to recognize income and make distributions to shareholders before it receives any cash payments on the securities. To generate cash to satisfy those distribution requirements, a fund may have to sell portfolio securities that it otherwise might have continued to hold or to use cash flows from other sources such as the sale of fund shares.
Investments in debt obligations that are at risk of or in default present tax issues for a fund. Tax rules are not entirely clear about issues such as whether and to what extent a fund should recognize market discount on a debt obligation, when a fund may cease to accrue interest, original issue discount or market discount, when and to what extent a fund may take deductions for bad debts or worthless securities and how a fund
59

should allocate payments received on obligations in default between principal and income. These and other related issues will be addressed by a fund in order to ensure that it distributes sufficient income to preserve its status as a regulated investment company.
Options, futures, forward contracts, swap agreements and hedging transactions. In general, option premiums received by a fund are not immediately included in the income of the fund. Instead, the premiums are recognized when the option contract expires, the option is exercised by the holder, or the fund transfers or otherwise terminates the option (e.g., through a closing transaction). If an option written by a fund is exercised and the fund sells or delivers the underlying stock, the fund generally will recognize capital gain or loss equal to (a) the sum of the strike price and the option premium received by the fund minus (b) the fund’s basis in the stock. Such gain or loss generally will be short-term or long-term depending upon the holding period of the underlying stock. If securities are purchased by a fund pursuant to the exercise of a put option written by it, the fund generally will subtract the premium received from its cost basis in the securities purchased. The gain or loss with respect to any termination of a fund’s obligation under an option other than through the exercise of the option and related sale or delivery of the underlying stock generally will be short-term gain or loss depending on whether the premium income received by the fund is greater or less than the amount paid by the fund (if any) in terminating the transaction. Thus, for example, if an option written by a fund expires unexercised, the fund generally will recognize short-term gain equal to the premium received.
The tax treatment of certain futures contracts entered into by a fund as well as listed non-equity options written or purchased by the fund on U.S. exchanges (including options on futures contracts, broad-based equity indices and debt securities) may be governed by section 1256 of the Code (section 1256 contracts). Gains or losses on section 1256 contracts generally are considered 60% long-term and 40% short-term capital gains or losses (60/40), although certain foreign currency gains and losses from such contracts may be treated as ordinary in character. Also, any section 1256 contracts held by a fund at the end of each taxable year (and, for purposes of the 4% excise tax, on certain other dates as prescribed under the Code) are “marked-to-market” with the result that unrealized gains or losses are treated as though they were realized and the resulting gain or loss is treated as ordinary or 60/40 gain or loss, as applicable. Section 1256 contracts do not include any interest rate swap, currency swap, basis swap, interest rate cap, interest rate floor, commodity swap, equity swap, equity index swap, credit default swap or similar agreement.
In addition to the special rules described above in respect of options and futures transactions, a fund’s transactions in other derivative instruments (including options, forward contracts and swap agreements) as well as its other hedging, short sale, or similar transactions, may be subject to one or more special tax rules (including the constructive sale, notional principal contract, straddle, wash sale and short sale rules). These rules may affect whether gains and losses recognized by a fund are treated as ordinary or capital or as short-term or long-term, accelerate the recognition of income or gains to the fund, defer losses to the fund, and cause adjustments in the holding periods of the fund’s securities. These rules, therefore, could affect the amount, timing and/or character of distributions to shareholders. Moreover, because the tax rules applicable to derivative financial instruments are in some cases uncertain under current law, an adverse determination or future guidance by the IRS with respect to these rules (which determination or guidance could be retroactive) may affect whether a fund has made sufficient distributions and otherwise satisfied the relevant requirements to maintain its qualification as a regulated investment company and avoid a fund-level tax.
Certain of a fund’s investments in derivatives and foreign currency-denominated instruments, and the fund’s transactions in foreign currencies and hedging activities, may produce a difference between its book income and its taxable income. If a fund’s book income is less than the sum of its taxable income and net tax-exempt income (if any), the fund could be required to make distributions exceeding book income to qualify as a regulated investment company. If a fund’s book income exceeds the sum of its taxable income and net tax-exempt income (if any), the distribution of any such excess will be treated as (i) a dividend to the extent of the fund’s remaining earnings and profits (including current earnings and profits arising from tax-exempt income, reduced by related deductions), (ii) thereafter, as a return of capital to the extent of the recipient’s basis in the shares, and (iii) thereafter, as gain from the sale or exchange of a capital asset.
60

Foreign currency transactions. A fund’s transactions in foreign currencies, foreign currency-denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This treatment could increase or decrease a fund’s ordinary income distributions to you, and may cause some or all of the fund’s previously distributed income to be classified as a return of capital. In certain cases, a fund may make an election to treat such gain or loss as capital.
PFIC investments. A fund may invest in securities of foreign companies that may be classified under the Code as PFICs. In general, a foreign company is classified as a PFIC if at least one-half of its assets constitute investment-type assets or 75% or more of its gross income is investment-type income. When investing in PFIC securities, a fund intends to mark-to-market these securities under certain provisions of the Code and recognize any unrealized gains as ordinary income at the end of the fund’s fiscal and excise tax years. Deductions for losses are allowable only to the extent of any current or previously recognized gains. These gains (reduced by allowable losses) are treated as ordinary income that a fund is required to distribute, even though it has not sold or received dividends from these securities. You should also be aware that the designation of a foreign security as a PFIC security will cause its income dividends to fall outside of the definition of qualified foreign corporation dividends. These dividends generally will not qualify for the reduced rate of taxation on qualified dividends when distributed to you by a fund. Foreign companies are not required to identify themselves as PFICs. Due to various complexities in identifying PFICs, a fund can give no assurances that it will be able to identify portfolio securities in foreign corporations that are PFICs in time for the fund to make a mark-to-market election. If a fund is unable to identify an investment as a PFIC and thus does not make a mark-to-market election, the fund may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the fund to its shareholders. Additional charges in the nature of interest may be imposed on a fund in respect of deferred taxes arising from such distributions or gains.
Investments in non-U.S. REITs. While non-U.S. REITs often use complex acquisition structures that seek to minimize taxation in the source country, an investment by a fund in a non-U.S. REIT may subject the fund, directly or indirectly, to corporate taxes, withholding taxes, transfer taxes and other indirect taxes in the country in which the real estate acquired by the non-U.S. REIT is located. The fund's pro rata share of any such taxes will reduce the fund's return on its investment. A fund's investment in a non-U.S. REIT may be considered an investment in a PFIC, as discussed above  in “Tax Treatment of Portfolio Transactions – PFIC investments.” Additionally, foreign withholding taxes on distributions from the non-U.S. REIT may be reduced or eliminated under certain tax treaties, as discussed above in “Taxation of the Fund – Foreign income tax.” Also, the fund in certain limited circumstances may be required to file an income tax return in the source country and pay tax on any gain realized from its investment in the non-U.S. REIT under rules similar to those in the United States which tax foreign persons on gain realized from dispositions of interests in U.S. real estate.
Investments in U.S. REITs. A U.S. REIT is not subject to federal income tax on the income and gains it distributes to shareholders. Dividends paid by a U.S. REIT, other than capital gain distributions, will be taxable as ordinary income up to the amount of the U.S. REIT’s current and accumulated earnings and profits. Capital gain dividends paid by a U.S. REIT to a fund will be treated as long-term capital gains by the fund and, in turn, may be distributed by the fund to its shareholders as a capital gain distribution.  Because of certain noncash expenses, such as property depreciation, an equity U.S. REIT’s cash flow may exceed its taxable income.  The equity U.S. REIT, and in turn a fund, may distribute this excess cash to shareholders in the form of a return of capital distribution. However, if a U.S. REIT is operated in a manner that fails to qualify as a REIT, an investment in the U.S. REIT would become subject to double taxation, meaning the taxable income of the U.S. REIT would be subject to federal income tax at the corporate income tax rate without any deduction for dividends paid to shareholders and the dividends would be taxable to shareholders as ordinary income (or possibly as qualified dividend income) to the extent of the U.S. REIT’s current and accumulated earnings and profits. Also, see “Tax Treatment of Portfolio Transactions — Investment in taxable mortgage pools (excess
61

inclusion income)” and “Foreign Shareholders — U.S. withholding tax at the source” with respect to certain other tax aspects of investing in U.S. REITs.
Investment in taxable mortgage pools (excess inclusion income). Under a Notice issued by the IRS, the Code and Treasury regulations to be issued, a portion of a fund’s income from a U.S. REIT that is attributable to the REIT’s residual interest in a real estate mortgage investment conduit (REMIC) or equity interests in a “taxable mortgage pool” (referred to in the Code as an excess inclusion) will be subject to federal income tax in all events. The excess inclusion income of a regulated investment company, such as a fund, will be allocated to shareholders of the regulated investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related REMIC residual interest or, if applicable, taxable mortgage pool directly. In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income (UBTI) to entities (including qualified pension plans, individual retirement accounts, 401(k) plans, Keogh plans or other tax-exempt entities) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a foreign stockholder, will not qualify for any reduction in U.S. federal withholding tax. In addition, if at any time during any taxable year a “disqualified organization” (which generally includes certain cooperatives, governmental entities, and tax-exempt organizations not subject to tax on UBTI) is a record holder of a share in a regulated investment company, then the regulated investment company will be subject to a tax equal to that portion of its excess inclusion income for the taxable year that is allocable to the disqualified organization, multiplied by the corporate income tax rate. The Notice imposes certain reporting requirements upon regulated investment companies that have excess inclusion income.  There can be no assurance that a fund will not allocate to shareholders excess inclusion income.
These rules are potentially applicable to a fund with respect to any income it receives from the equity interests of certain mortgage pooling vehicles, either directly or, as is more likely, through an investment in a U.S. REIT.  It is unlikely that these rules will apply to a fund that has a non-REIT strategy.
Investments in partnerships and QPTPs. For purposes of the Income Requirement, income derived by a fund from a partnership that is not a QPTP will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership that would be qualifying income if realized directly by the fund. While the rules are not entirely clear with respect to a fund investing in a partnership outside a master-feeder structure, for purposes of testing whether a fund satisfies the Asset Diversification Test, the fund generally is treated as owning a pro rata share of the underlying assets of a partnership. See “Taxation of the Fund — Qualification as a regulated investment company.” In contrast, different rules apply to a partnership that is a QPTP. A QPTP is a partnership (a) the interests in which are traded on an established securities market, (b) that is treated as a partnership for federal income tax purposes, and (c) that derives less than 90% of its income from sources that satisfy the Income Requirement (e.g., because it invests in commodities). All of the net income derived by a fund from an interest in a QPTP will be treated as qualifying income but the fund may not invest more than 25% of its total assets in one or more QPTPs. However, there can be no assurance that a partnership classified as a QPTP in one year will qualify as a QPTP in the next year. Any such failure to annually qualify as a QPTP might, in turn, cause a fund to fail to qualify as a regulated investment company. Although, in general, the passive loss rules of the Code do not apply to RICs, such rules do apply to a fund with respect to items attributable to an interest in a QPTP. Fund investments in partnerships, including in QPTPs, may result in the fund being subject to state, local or foreign income, franchise or withholding tax liabilities.
If an MLP is treated as a partnership for U.S. federal income tax purposes (whether or not a QPTP), all or portion of the dividends received by a fund from the MLP likely will be treated as a return of capital for U.S. federal income tax purposes because of accelerated deductions available with respect to the activities of such MLPs. Further, because of these accelerated deductions, on the disposition of interests in such an MLP, a fund likely will realize taxable income in excess of economic gain with respect to those MLP interests (or if the fund does not dispose of the MLP, the fund could realize taxable income in excess of cash flow with respect to the MLP in a later period), and the fund must take such income into account in determining whether the fund
62

has satisfied its Distribution Requirement. A fund may have to borrow or liquidate securities to satisfy its Distribution Requirement and to meet its redemption requests, even though investment considerations might otherwise make it undesirable for the fund to sell securities or borrow money at such time. In addition, any gain recognized, either upon the sale of a fund’s MLP interest or sale by the MLP of property held by it, including in excess of economic gain thereon, treated as so-called “recapture income,” will be treated as ordinary income. Therefore, to the extent a fund invests in MLPs, fund shareholders might receive greater amounts of distributions from the fund taxable as ordinary income than they otherwise would in the absence of such MLP investments.
Although MLPs are generally expected to be treated as partnerships for U.S. federal income tax purposes, some MLPs may be treated as PFICs or “regular” corporations for U.S. federal income tax purposes. The treatment of particular MLPs for U.S. federal income tax purposes will affect the extent to which a fund can invest in MLPs and will impact the amount, character, and timing of income recognized by the Fund.
Investments in commodities ― structured notes, corporate subsidiary and certain ETFs. Gains from the disposition of commodities, including precious metals, will neither be considered qualifying income for purposes of satisfying the Income Requirement nor qualifying assets for purposes of satisfying the Asset Diversification Test. See “Taxation of the Fund — Qualification as a regulated investment company.” Also, the IRS has issued a revenue ruling which holds that income derived from commodity-linked swaps is not qualifying income for purposes of the Income Requirement. In a subsequent revenue ruling, as well as in a number of follow-on private letter rulings (upon which only the fund that received the private letter ruling may rely), the IRS provides that income from certain alternative investments which create commodity exposure, such as certain commodity-linked or structured notes or a corporate subsidiary that invests in commodities, may be considered qualifying income under the Code. However, the portion of such rulings relating to the treatment of a corporation as a regulated investment company that require a determination of whether a financial instrument or position is a security under section 2(a)(36) of the 1940 Act was revoked because of changes in the IRS's position. (A financial instrument or position that constitutes a security under section 2(a)(36) of the 1940 Act generates qualifying income for a corporation taxed as a regulated investment company.) Accordingly, a fund may invest in certain commodity-linked notes relying on an opinion of counsel confirming that income from such investments should be qualifying income because such commodity-linked notes constitute securities under section 2(a)(36) of the 1940 Act. In addition, a RIC may gain exposure to commodities through investment in a QPTP, such as an exchange-traded fund or ETF that is classified as a partnership and which invests in commodities, or through investment in a wholly-owned foreign subsidiary that is treated as a controlled foreign corporation for federal income tax purposes. Treasury regulations treat “Subpart F” income (defined in Section 951 of the Code to include passive income such as income from commodity-linked derivatives) as qualifying income, even if a foreign corporation, such as a wholly-owned foreign subsidiary, does not make a distribution of such income. If a distribution is made, such income will be treated as a dividend by the Funds to the extent that, under applicable provisions of the Code, there is a distribution out of the earnings and profits of the foreign corporation attributable to the distribution. Accordingly, the extent to which a fund directly invests in commodities or commodity-linked derivatives may be limited by the Income Requirement and the Asset Diversification Test, which the fund must continue to satisfy to maintain its status as a regulated investment company. A fund also may be limited in its ability to sell its investments in commodities, commodity-linked derivatives, and certain ETFs or be forced to sell other investments to generate income due to the Income Requirement. If a fund does not appropriately limit such investments or if such investments (or the income earned on such investments) were to be recharacterized for U.S. tax purposes, the fund could fail to qualify as a regulated investment company. In lieu of potential disqualification, a fund is permitted to pay a tax for certain failures to satisfy the Asset Diversification Test or Income Requirement, which, in general, are limited to those due to reasonable cause and not willful neglect.
Securities lending. While securities are loaned out by a fund, the fund generally will receive from the borrower amounts equal to any dividends or interest paid on the borrowed securities. For federal income tax purposes, payments made “in lieu of” dividends are not considered dividend income. These distributions will
63

neither qualify for the reduced rate of taxation for individuals on qualified dividends nor the 50% dividends-received deduction for corporations. Also, any foreign tax withheld on payments made “in lieu of” dividends or interest will not qualify for the pass-through of foreign tax credits to shareholders. Additionally, in the case of a fund with a strategy of investing in tax-exempt securities, any payments made “in lieu of” tax-exempt interest will be considered taxable income to the fund, and thus, to the investors, even though such interest may be tax-exempt when paid to the borrower.
Investments in convertible securities. Convertible debt is ordinarily treated as a “single property” consisting of a pure debt interest until conversion, after which the investment becomes an equity interest. If the security is issued at a premium (i.e., for cash in excess of the face amount payable on retirement), the creditor-holder may amortize the premium over the life of the bond. If the security is issued for cash at a price below its face amount, the creditor-holder must accrue original issue discount in income over the life of the debt. The creditor-holder’s exercise of the conversion privilege is treated as a nontaxable event. Mandatorily convertible debt (e.g., an exchange-traded note or ETN issued in the form of an unsecured obligation that pays a return based on the performance of a specified market index, exchange currency, or commodity) is often, but not always, treated as a contract to buy or sell the reference property rather than debt. Similarly, convertible preferred stock with a mandatory conversion feature is ordinarily, but not always, treated as equity rather than debt. Dividends received generally are qualified dividend income and eligible for the corporate dividends-received deduction. In general, conversion of preferred stock for common stock of the same corporation is tax-free. Conversion of preferred stock for cash is a taxable redemption. Any redemption premium for preferred stock that is redeemable by the issuing company might be required to be amortized under original issue discount principles. A change in the conversion ratio or conversion price of a convertible security on account of a dividend paid to the issuer’s other shareholders may result in a deemed distribution of stock to the holders of the convertible security equal to the value of their increased interest in the equity of the issuer. Thus, an increase in the conversion ratio of a convertible security can be treated as a taxable distribution of stock to a holder of the convertible security (without a corresponding receipt of cash by the holder) before the holder has converted the security.
Tax Certification and Backup Withholding. Tax certification and backup withholding tax laws may require that you certify your tax information when you become an investor in the Fund. For U.S. citizens and resident aliens, this certification is made on IRS Form W-9. Under these laws, the Fund must withhold a portion of your taxable distributions and sales proceeds unless you:
provide your correct Social Security or taxpayer identification number;
certify that this number is correct;
certify that you are not subject to backup withholding; and
certify that you are a U.S. person (including a U.S. resident alien).
The Fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 24% of any distributions or proceeds paid. Backup withholding is not an additional tax. Any amounts withheld may be credited against the shareholder’s U.S. federal income tax liability, provided the appropriate information is furnished to the IRS. Certain payees and payments are exempt from backup withholding and information reporting.
Non-U.S. investors have special U.S. tax certification requirements. See “Foreign Shareholders — Tax certification and backup withholding.”
Foreign Shareholders. Shareholders who, as to the United States, are nonresident alien individuals, foreign trusts or estates, foreign corporations, or foreign partnerships (foreign shareholder), may be subject to U.S. withholding and estate tax and are subject to special U.S. tax certification requirements.
Taxation of a foreign shareholder depends on whether the income from the Fund is “effectively connected” with a U.S. trade or business carried on by such shareholder.
64

U.S. withholding tax at the source. If the income from the Fund is not effectively connected with a U.S. trade or business carried on by a foreign shareholder, distributions to such shareholder will be subject to U.S. withholding tax at the rate of 30% (or lower treaty rate) upon the gross amount of the distribution, subject to certain exemptions including those for dividends reported by the Fund to shareholders as:
exempt-interest dividends paid by the Fund from its net interest income earned on municipal securities;
capital gain dividends paid by the Fund from its net long-term capital gains (other than those from disposition of a U.S. real property interest), unless you are a nonresident alien present in the United States for a period or periods aggregating 183 days or more during the calendar year; and
interest-related dividends paid by the Fund from its qualified net interest income from U.S. sources and short-term capital gain dividends.
However, the Fund(with the possible exceptions of Invesco Treasury Portfolio and Invesco Government & Agency Portfolio) does not intend to utilize the exemptions for interest-related dividends paid and short-term capital gain dividends paid. Moreover, notwithstanding such exemptions from U.S. withholding at the source, any dividends and distributions of income and capital gains, including the proceeds from the sale of your Fund shares, will be subject to backup withholding at a rate of 24% if you fail to properly certify that you are not a U.S. person.
Foreign shareholders may be subject to U.S. withholding tax at a rate of 30% on the income resulting from an election to pass-through foreign tax credits to shareholders, but may not be able to claim a credit or deduction with respect to the withholding tax for the foreign tax treated as having been paid by them.
Amounts reported by the Fund to shareholders as capital gain dividends (a) that are attributable to certain capital gain dividends received from a qualified investment entity (QIE) (generally defined as either (i) a U.S. REIT or (ii) a RIC classified as a “U.S. real property holding corporation” or which would be if the exceptions for holding 5% or less of a class of publicly traded shares or an interest in a domestically controlled QIE did not apply), or (b) that are realized by the Fund on the sale of a “U.S. real property interest” (including gain realized on the sale of shares in a QIE other than one that is domestically controlled), will not be exempt from U.S. federal income tax and may be subject to U.S. withholding tax at the rate of 30% (or lower treaty rate) if the Fund by reason of having a REIT strategy is classified as a QIE. If the Fund is so classified, foreign shareholders owning more than 5% of the Fund’s shares may be treated as realizing gain from the disposition of a U.S. real property interest, causing Fund distributions to be subject to U.S. withholding tax at the corporate income tax rate, and requiring the filing of a nonresident U.S. income tax return. In addition, if the Fund is classified as a QIE, anti-avoidance rules apply to certain wash sale transactions. Namely, if the Fund is a domestically controlled QIE and a foreign shareholder disposes of the Fund’s shares prior to the Fund paying a distribution attributable to the disposition of a U.S. real property interest and the foreign shareholder later acquires an identical stock interest in a wash sale transaction, the foreign shareholder may still be required to pay U.S. tax on the Fund’s distribution. Also, the sale of shares of the Fund, if classified as a “U.S. real property holding corporation,” could also be considered a sale of a U.S. real property interest with any resulting gain from such sale being subject to U.S. tax as income “effectively connected with a U.S. trade or business.”
Income effectively connected with a U.S. trade or business. If the income from the Fund is effectively connected with a U.S. trade or business carried on by a foreign shareholder, then ordinary income dividends, capital gain dividends and any gains realized upon the sale or redemption of shares of the Fund will be subject to U.S. federal income tax at the rates applicable to U.S. citizens or domestic corporations and require the filing of a nonresident U.S. income tax return.
Tax certification and backup withholding. Foreign shareholders may have special U.S. tax certification requirements to avoid backup withholding (at a rate of 24%) and, if applicable, to obtain the benefit of any income tax treaty between the foreign shareholder’s country of residence and the United States. To claim these tax benefits, the foreign shareholder must provide a properly completed Form W-8BEN (or other Form W-8, where applicable, or their substitute forms) to establish his or her status as a non-U.S. investor, to claim
65

beneficial ownership over the assets in the account, and to claim, if applicable, a reduced rate of or exemption from withholding tax under the applicable treaty. A Form W-8BEN provided without a U.S. taxpayer identification number remains in effect for a period of three years beginning on the date that it is signed and ending on the last day of the third succeeding calendar year. However, non-U.S. investors must advise the Fund of any changes of circumstances that would render the information given on the form incorrect, and must then provide a new W-8BEN to avoid the prospective application of backup withholding. Forms W-8BEN with U.S. taxpayer identification numbers remain valid indefinitely, or until the investor has a change of circumstances that renders the form incorrect and necessitates a new form and tax certification. Certain payees and payments are exempt from backup withholding.
Foreign Account Tax Compliance Act (FATCA). Under FATCA, the Fund will be required to withhold a 30% tax on income dividends made by the Fund to certain foreign entities, referred to as foreign financial institutions (FFI) or non-financial foreign entities (NFFE). After December 31, 2018, FATCA withholding also would have applied to certain capital gain distributions, return of capital distributions and the proceeds arising from the sale of Fund shares; however, based on proposed regulations issued by the IRS, which can be relied upon currently, such withholding is no longer required unless final regulations provide otherwise (which is not expected). The FATCA withholding tax generally can be avoided: (a) by an FFI, if it reports certain direct and indirect ownership of foreign financial accounts held by U.S. persons with the FFI and (b) by an NFFE, if it: (i) certifies that it has no substantial U.S. persons as owners or (ii) if it does have such owners, reporting information relating to them. The U.S. Treasury has negotiated intergovernmental agreements (IGA) with certain countries and is in various stages of negotiations with a number of other foreign countries with respect to one or more alternative approaches to implement FATCA.
An FFI can avoid FATCA withholding if it is deemed compliant or by becoming a “participating FFI,” which requires the FFI to enter into a U.S. tax compliance agreement with the IRS under section 1471(b) of the Code (FFI agreement) under which it agrees to verify, report and disclose certain of its U.S. accountholders and meet certain other specified requirements. The FFI will either report the specified information about the U.S. accounts to the IRS, or, to the government of the FFI’s country of residence (pursuant to the terms and conditions of applicable law and an applicable IGA entered into between the U.S. and the FFI’s country of residence), which will, in turn, report the specified information to the IRS. An FFI that is resident in a country that has entered into an IGA with the U.S. to implement FATCA will be exempt from FATCA withholding provided that the FFI shareholder and the applicable foreign government comply with the terms of such agreement.
An NFFE that is the beneficial owner of a payment from the Fund can avoid the FATCA withholding tax generally by certifying that it does not have any substantial U.S. owners or by providing the name, address and taxpayer identification number of each substantial U.S. owner. The NFFE will report the information to the Fund or other applicable withholding agent, which will, in turn, report the information to the IRS.
Such foreign shareholders also may fall into certain exempt, excepted or deemed compliant categories as established by U.S. Treasury regulations, IGAs, and other guidance regarding FATCA. An FFI or NFFE that invests in the Fund will need to provide the Fund with documentation properly certifying the entity’s status under FATCA in order to avoid FATCA withholding. Non-U.S. investors should consult their own tax advisors regarding the impact of these requirements on their investment in the Fund. The requirements imposed by FATCA are different from, and in addition to, the U.S. tax certification rules to avoid backup withholding described above. Shareholders are urged to consult their tax advisors regarding the application of these requirements to their own situation.
U.S. estate tax. Transfers by gift of shares of the Fund by a foreign shareholder who is a nonresident alien individual will not be subject to U.S. federal gift tax. An individual who, at the time of death, is a foreign shareholder will nevertheless be subject to U.S. federal estate tax with respect to shares at the graduated rates applicable to U.S. citizens and residents, unless a treaty exemption applies. If a treaty exemption is available, a decedent’s estate may nonetheless need to file a U.S. estate tax return to claim the exemption in order to obtain a U.S. federal transfer certificate. The transfer certificate will identify the property (i.e., Fund
66

shares) as to which the U.S. federal estate tax lien has been released. In the absence of a treaty, there is a $13,000 statutory estate tax credit (equivalent to an estate with assets of $60,000).
Local Tax Considerations. Rules of state and local taxation of ordinary income, qualified dividend income and capital gain dividends may differ from the rules for U.S. federal income taxation described above. Distributions may also be subject to additional state, local and foreign taxes depending on each shareholder’s particular situation.
DISTRIBUTION OF SECURITIES

The Compensation Plan compensates Invesco Distributors for expenses incurred for the purpose of financing any activity that is primarily intended to result in the sale of shares of the Funds. Such activities include, but are not limited to, the following: printing and distributing prospectuses and reports used for sales purposes, preparing and distributing sales literature (and any related services), advertisements, payment of dealer commissions and wholesaler compensation in connection with sales of certain Fund’s Class A [and Class AX] shares exceeding a certain amount set forth in the prospectus for such Fund (for which the Fund imposes no sales charge) and other distribution-related services permitted by Rule 12b-1.
Payments pursuant to the Plan are subject to any applicable limitations imposed by FINRA rules.
See Appendix K for a list of the amounts paid by each class of shares of each Fund pursuant to its distribution plan for the fiscal year or periods, as applicable, and Appendix L for an estimate by category of the allocation of actual fees paid by shares of each Fund pursuant to its distribution plan for the last fiscal year or periods, as applicable.
As required by Rule 12b-1, the Plan was approved by a majority of the Board, including a majority of the trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust and who have no direct or indirect financial interest in the operation of the Plan or in any agreements related to the Plan (the Rule 12b-1 Trustees). In approving the Plan in accordance with the requirements of Rule 12b-1, the trustees considered various factors and determined that there is a reasonable likelihood that the Plan would benefit each class of the Funds and its respective shareholders.
The anticipated benefits that may result from the Plan with respect to each Fund and/or the classes of each Fund and its shareholders include but are not limited to the following: (i) an increase in assets which may result in a diversified shareholder base, thereby reducing the outflow risk to other shareholders in the Funds; (ii) an increase in assets which may reduce expenses as fixed dollar costs are allocated across a larger asset base and/or allow a Fund to reach advisory fee breakpoints; (iii) increased scale could increase the likelihood of name recognition and the profile of a Fund in its asset space, thereby improving the momentum for asset generation.
67

Unless terminated earlier in accordance with their terms, the Plan continues from year to year as long as such continuance is specifically approved, at least annually by the Board, including a majority of the Rule 12b-1 Trustees. A Plan may be terminated at any time in whole or with respect to a Fund or class by the vote of a majority of the Rule 12b-1 Trustees or by the vote of a majority of the outstanding voting securities of that class.
Any amendment to the Plan that would increase materially the distribution expenses paid by the applicable class requires shareholder approval; otherwise, the Plan may be amended by the trustees, including a majority of the Rule 12b-1 Trustees, by votes cast at a meeting called for the purpose of voting upon such amendment. As long as the Plan is in effect, the Board shall satisfy the fund governance standards as defined in Rule 0-1(a)(7) under the 1940 Act.
The Compensation Plans obligate the Funds to pay Invesco Distributors the full amount of the distribution and service fees reflected on the schedules to those plans. Thus, even if Invesco Distributors’ actual allocated share of expenses exceeds the fee payable to Invesco Distributors at any given time, under the Compensation Plan, the Funds will not be obligated to pay more than that fee. If Invesco Distributors’ actual allocated share of expenses is less than the fee it receives, under the Compensation Plan, Invesco Distributors will retain the full amount of the fee.
Invesco Distributors may from time to time waive or reduce any portion of its 12b-1 fee. Voluntary fee waivers or reductions may be rescinded at any time without further notice to investors. During periods of voluntary fee waivers or reductions, Invesco Distributors will retain its ability to be reimbursed for such fee prior to the end of each fiscal year.
The Funds may pay a service fee of up to the cap disclosed in the Fund’s Plan and in any case no greater than 0.25% of the average daily net assets of the its shares, attributable to the customers’ selected dealers and financial institutions to such dealers and financial institutions, including Invesco Distributors, acting as principal, who furnish continuing personal shareholder services and/or maintenance of accounts to their customers who purchase and own the applicable class of shares of the Fund. Under the terms of a shareholder service agreement, such personal shareholder services and/or maintenance of accounts may include, but are not limited to, assisting in establishing and maintaining customer accounts and records, assisting with purchase and redemption requests, arranging for bank wires, monitoring dividend payments from a Fund on behalf of customers, forwarding certain shareholder communications from a Fund to customers, receiving and answering correspondence, aiding in maintaining the investment of their respective customers in a Fund and providing such other information and services as reasonably requested. Any amounts not paid as a service fee under each Plan would constitute an asset-based sales charge.
The Funds may agree to pay fees to selected dealers and other institutions who render the foregoing services to their customers subject to an agreement. Fees shall be paid only to those selected dealers or other institutions who are dealers or institutions of record at the close of business on the last business day of the applicable payment period for the account in which such Fund’s shares are held.
Selected dealers and other institutions entitled to receive compensation for selling Fund shares may receive different compensation for selling shares of one particular class over another. Under the Plan, certain financial institutions which have entered into service agreements and which sell shares of the Funds, may receive payments from the Funds pursuant to the Plan in an amount not to exceed the maximum annual rate to be paid to Invesco Distributors under the Plan. These payments are an obligation of the Funds and not of Invesco Distributors.
Invesco Distributors has voluntarily undertaken to waive or reduce 12b-1 fees to the extent necessary to assist the Funds in attempting to maintain a positive yield. There is no guarantee that a Fund will maintain a positive yield. That undertaking may be amended or rescinded at any time.
Distributor
The Trust has entered into a master distribution agreement relating to the Funds (the Distribution Agreement) with Invesco Distributors, a registered broker-dealer and a wholly-owned subsidiary of Invesco,
68

pursuant to which Invesco Distributors acts as the distributor of the shares of each class of the Funds. The address of Invesco Distributors is 11 Greenway Plaza, Suite 1000, Houston, Texas 77046-1173. Certain trustees and officers of the Trust are affiliated with Invesco Distributors. See “Management of the Trust.”
The Distribution Agreement provides Invesco Distributors with the exclusive right to distribute the shares of each class of the Funds on a continuous basis directly and through other broker dealers with whom Invesco Distributors has entered into selected dealer agreements. Invesco Distributors has not undertaken to sell any specified number of shares of any classes of the Funds. The Distribution Agreement also provides that Invesco Distributors will pay promotional expenses, including the incremental costs of printing prospectuses and statements of additional information, annual reports and other periodic reports for distribution to persons who are not shareholders of the Trust and the costs of preparing and distributing any other supplemental sales literature.
The Trust (on behalf of any class of the Funds) or Invesco Distributors may terminate the Distribution Agreement on sixty (60) days’ written notice without penalty. The Distribution Agreement will terminate automatically in the event of its assignment.
Invesco Distributors may, from time to time at its expense, pay a fee to broker-dealers, banks or other financial institutions for operations and/or marketing support, including support for distribution programs or platforms. Such fees will not impose additional expenses on a class, nor will they change the price paid by investors for the purchase of the applicable classes’ shares or the amount that any particular class will receive as proceeds from such sales.
FINANCIAL STATEMENTS
The audited financial statements for the Funds’ most recent fiscal year ended August 31, 2021, including the notes thereto and the reports of PricewaterhouseCoopers LLP thereon, are incorporated by reference to the annual reports to shareholders for the Funds contained in the Form N-CSR filed on November 4, 2021.
The portions of such annual reports that are not specifically listed above are not incorporated by reference into this SAI and are not a part of this Registration Statement.

APPENDIX A - RATINGS OF DEBT SECURITIES
The following is a description of the factors underlying the debt ratings of Moody's, S&P, and Fitch.
Moody's Long-Term Debt Ratings
Aaa: Obligations rated 'Aaa' are judged to be of the highest quality, subject to the lowest level of credit risk.
Aa: Obligations rated 'Aa' are judged to be of high quality and are subject to very low credit risk.
A: Obligations rated 'A' are judged to be upper-medium grade and are subject to low credit risk.
Baa: Obligations rated 'Baa' are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.
Ba: Obligations rated 'Ba' are judged to be speculative and are subject to substantial credit risk.
B: Obligations rated 'B' are considered speculative and are subject to high credit risk.
Caa: Obligations rated 'Caa' are judged to be speculative of poor standing and are subject to very high credit risk.
Ca: Obligations rated 'Ca' are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.
C: Obligations rated 'C' are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.
Note: Moody's appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a “(hyb)” indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms*.
* By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.
Moody's Short-Term Prime Rating System
P-1: Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.
P-2: Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.
P-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.
NP (Not Prime): Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.
A-1

Moody's MIG/VMIG US Short-Term Ratings
Short-Term Obligation Ratings
We use the global short-term Prime rating scale for commercial paper issued by US municipalities and nonprofits. These commercial paper programs may be backed by external letters of credit or liquidity facilities, or by an issuer’s self-liquidity.
For other short-term municipal obligations, we use one of two other short-term rating scales, the Municipal Investment Grade (MIG) and Variable Municipal Investment Grade (VMIG) scales discussed below.
We use the MIG scale for US municipal cash flow notes, bond anticipation notes and certain other short-term obligations, which typically mature in three years or less. Under certain circumstances, we use the MIG scale for bond anticipation notes with maturities of up to five years.
MIG 1: This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.
MIG 2: This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.
MIG 3: This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.
SG: This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.
Demand Obligation Ratings
In the case of variable rate demand obligations (VRDOs), a two-component rating is assigned. The components are a long-term rating and a short-term demand obligation rating. The long-term rating addresses the issuer’s ability to meet scheduled principal and interest payments. The short-term demand obligation rating addresses the ability of the issuer or the liquidity provider to make payments associated with the purchase-price-upon-demand feature (“demand feature”) of the VRDO. The short-term demand obligation rating uses the VMIG scale. VMIG ratings with liquidity support use as an input the short-term Counterparty Risk Assessment of the support provider, or the long-term rating of the underlying obligor in the absence of third party liquidity support. Transitions of VMIG ratings of demand obligations with conditional liquidity support differ from transitions on the Prime scale to reflect the risk that external liquidity support will terminate if the issuer’s long-term rating drops below investment grade. Please see our methodology that discusses demand obligations with conditional liquidity support.
We typically assign the VMIG short-term demand obligation rating if the frequency of the demand feature is less than every three years. If the frequency of the demand feature is less than three years but the purchase price is payable only with remarketing proceeds, the short-term demand obligation rating is “NR”.
VMIG 1: This designation denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
VMIG 2: This designation denotes strong credit quality. Good protection is afforded by the strong short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
VMIG 3: This designation denotes acceptable credit quality. Adequate protection is afforded by the satisfactory short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
SG: This designation denotes speculative-grade credit quality. Demand features rated in this category may be supported by a liquidity provider that does not have an investment grade short-term rating or

Standard & Poor's Long-Term Issue Credit Ratings
Issue credit ratings are based, in varying degrees, on S&P Global Ratings’ analysis of the following considerations:
The likelihood of payment--the capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;
The nature and provisions of the financial obligation, and the promise we impute; and
The protection afforded by, and relative position of, the financial obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights.
Issue ratings are an assessment of default risk but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)
AAA: An obligation rated 'AAA' has the highest rating assigned by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is extremely strong.
AA: An obligation rated 'AA' differs from the highest-rated obligations only to a small degree. The obligor's capacity to meet its financial commitments on the obligation is very strong.
A: An obligation rated 'A' is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitments on the obligation is still strong.
BBB: An obligation rated 'BBB' exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor’s capacity to meet its financial commitments on the obligation.
BB, B, CCC, CC and C: Obligations rated 'BB', 'B', 'CCC' 'CC', and 'C' are regarded as having significant speculative characteristics. 'BB' indicates the least degree of speculation and 'C' the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposure to adverse conditions.
BB: An obligation rated 'BB' is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor's inadequate capacity to meet its financial commitments on the obligation.
B: An obligation rated 'B' is more vulnerable to nonpayment than obligations rated 'BB', but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitments on the obligation.
CCC: An obligation rated 'CCC' is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation.
CC: An obligation rated 'CC' is currently highly vulnerable to nonpayment. The 'CC' rating is used when a default has not yet occurred but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.
A-3

C: An obligation rated 'C' is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.
D: An obligation rated 'D' is in default or in breach of an imputed promise. For non-hybrid capital instruments, the 'D' rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The 'D' rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to 'D' if it is subject to a distressed exchange offer.
Plus (+) or minus (-): The ratings from 'AA' to 'CCC' may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.
NR: This indicates that no rating has been requested, or that there is insufficient information on which to base a rating, or that S&P Global Ratings does not rate a particular obligation as a matter of policy.
Standard & Poor's Short-Term Issue Credit Ratings
A-1: An obligor rated 'A-1' has strong capacity to meet its financial commitments. It is rated in the highest category by S&P Global Ratings. Within this category, certain obligors are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitments is extremely strong.
A-2: An obligor rated 'A-2' has satisfactory capacity to meet its financial commitments. However, it is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligors in the highest rating category.
A-3: An obligor rated 'A-3' has adequate capacity to meet its financial obligations. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments.
B: An obligor rated 'B' is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties that could lead to the obligor's inadequate capacity to meet its financial commitments.
C: An obligor rated 'C' is currently vulnerable to nonpayment that would result in an 'D' issuer rating and is dependent upon favorable business, financial, and economic conditions to meet its financial commitments.
D: A short-term obligation rated 'D' is in default or in breach of an imputed promise. For non-hybrid capital instruments, the 'D' rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The 'D' rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to 'D' if it is subject to a distressed debt restructuring.
Standard & Poor's Municipal Short-Term Note Ratings Definitions
An S&P Global Ratings U.S. municipal note rating reflects S&P Global Ratings’ opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P Global Ratings’ analysis will review the following considerations:
Amortization schedule -- the larger final maturity relative to other maturities, the more likely it will be treated as a note; and
A-4

Source of payment -- the more dependent the issue is on the market for its refinancing, the more likely it will be treated as a note.
Note rating symbols are as follows:
SP-1: Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.
SP-2: Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.
SP-3: Speculative capacity to pay principal and interest.
D: ‘D’ is assigned upon failure to pay the note when due, completion of a distressed exchange offer, or the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions.
Standard & Poor's Dual Ratings
Dual ratings may be assigned to debt issues that have a put option or demand feature. The first component of the rating addresses the likelihood of repayment of principal and interest as due, and the second component of the rating addresses only the demand feature. The first component of the rating can relate to either a short-term or long-term transaction and accordingly use either short-term or long-term rating symbols. The second component of the rating relates to the put option and is assigned a short-term rating symbol (for example, 'AAA/A-1+' or 'A-1+/A-1'). With U.S. municipal short-term demand debt, the U.S. municipal short-term note rating symbols are used for the first component of the rating (for example, 'SP-1+/A-1+').
Fitch Credit Rating Scales
Fitch Ratings publishes opinions on a variety of scales. The most common of these are credit ratings, but the agency also publishes ratings, scores and other relative opinions relating to financial or operational strength. For example, Fitch also provides specialized ratings of servicers of residential and commercial mortgages, asset managers and funds. In each case, users should refer to the definitions of each individual scale for guidance on the dimensions of risk covered in each assessment.
Fitch’s credit ratings relating to issuers are an opinion on the relative ability of an entity to meet financial commitments, such as interest, preferred dividends, repayment of principal, insurance claims or counterparty obligations. Credit ratings relating to securities and obligations of an issuer can include a recovery expectation (please see section Specific Limitations Relating to Credit Rating Scales for details). Credit ratings are used by investors as indications of the likelihood of receiving the money owed to them in accordance with the terms on which they invested. The agency's credit ratings cover the global spectrum of corporate, sovereign financial, bank, insurance, and public finance entities (including supranational and sub-national entities) and the securities or other obligations they issue, as well as structured finance securities backed by receivables or other financial assets.
The terms “investment grade” and “speculative grade” have established themselves over time as shorthand to describe the categories ‘AAA’ to ‘BBB’ (investment grade) and ‘BB’ to ‘D’ (speculative grade). The terms investment grade and speculative grade are market conventions and do not imply any recommendation or endorsement of a specific security for investment purposes. Investment grade categories indicate relatively low to moderate credit risk, while ratings in the speculative categories either signal a higher level of credit risk or that a default has already occurred.
For the convenience of investors, Fitch may also include issues relating to a rated issuer that are not and have not been rated on its web page. Such issues are also denoted as ‘NR’.
Credit ratings express risk in relative rank order, which is to say they are ordinal measures of credit risk and are not predictive of a specific frequency of default or loss. For information about the historical
A-5

performance of ratings please refer to Fitch’s Ratings Transition and Default studies which detail the historical default rates and their meaning. The European Securities and Markets Authority also maintains a central repository of historical default rates.
Fitch’s credit ratings do not directly address any risk other than credit risk. In particular, ratings do not deal with the risk of a market value loss on a rated security due to changes in interest rates, liquidity and other market considerations. However, in terms of payment obligation on the rated liability, market risk may be considered to the extent that it influences the ability of an issuer to pay upon a commitment. Ratings nonetheless do not reflect market risk to the extent that they influence the size or other conditionality of the obligation to pay upon a commitment (for example, in the case of index-linked bonds).
In the default components of ratings assigned to individual obligations or instruments, the agency typically rates to the likelihood of non-payment or default in accordance with the terms of that instrument’s documentation. In limited cases, Fitch may include additional considerations (i.e. rate to a higher or lower standard than that implied in the obligation’s documentation).
The primary credit rating scales can be used to provide a rating of privately issued obligations or certain note issuance programs or for private ratings. In this case the rating is not published, but only provided to the issuer or its agents in the form of a rating letter.
The primary credit rating scales may also be used to provide ratings for a more narrow scope, including interest strips and return of principal or in other forms of opinions such as Credit Opinions or Rating Assessment Services. Credit Opinions are either a notch- or category-specific view using the primary rating scale and omit one or more characteristics of a full rating or meet them to a different standard. Credit Opinions will be indicated using a lower case letter symbol combined with either an '*' (e.g. 'bbb+*') or (cat) suffix to denote the opinion status. Credit Opinions will be point-in-time typically but may be monitored if the analytical group believes information will be sufficiently available. Rating Assessment Services are a notch-specific view using the primary rating scale of how an existing or potential rating may be changed by a given set of hypothetical circumstances. Rating Assessments are point-in-time opinions. Rating Assessments are not monitored; they are not placed on Watch or assigned an Outlook and are not published.
Fitch Long-Term Rating Scales
Issuer Default Ratings
Rated entities in a number of sectors, including financial and non-financial corporations, sovereigns, insurance companies and certain sectors within public finance, are generally assigned Issuer Default Ratings (IDRs). IDRs are also assigned to certain entities in global infrastructure and project finance. IDRs opine on an entity's relative vulnerability to default on financial obligations. The threshold default risk addressed by the IDR is generally that of the financial obligations whose non-payment would best reflect the uncured failure of that entity. As such, IDRs also address relative vulnerability to bankruptcy, administrative receivership or similar concepts.
In aggregate, IDRs provide an ordinal ranking of issuers based on the agency's view of their relative vulnerability to default, rather than a prediction of a specific percentage likelihood of default.
AAA: Highest credit quality.
'AAA' ratings denote the lowest expectation of default risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.
AA: Very high credit quality.
'AA' ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.
A-6

A: High credit quality.
'A' ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
BBB: Good credit quality.
'BBB' ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.
BB: Speculative.
'BB' ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists that supports the servicing of financial commitments.
B: Highly speculative.
'B' ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.
CCC: Substantial credit risk.
Default is a real possibility.
CC: Very high levels of credit risk.
Default of some kind appears probable.
C: Near default
A default or default-like process has begun, or the issuer is in standstill, or for a closed funding vehicle, payment capacity is irrevocably impaired. Conditions that are indicative of a 'C' category rating for an issuer include:
a. the issuer has entered into a grace or cure period following non-payment of a material financial obligation;
b. the issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation; or
c. the formal announcement by the issuer or their agent of a distressed debt exchange;
d. a closed financing vehicle where payment capacity is irrevocably impaired such that it is not expected to pay interest and/or principal in full during the life of the transaction, but where no payment default is imminent
RD: Restricted default.
‘RD’ ratings indicate an issuer that in Fitch’s opinion has experienced:
a. an uncured payment default or distressed debt exchange on a bond, loan or other material financial obligation, but
b. has not entered into bankruptcy filings, administration, receivership, liquidation, or other formal winding-up procedure, and
c. has not otherwise ceased operating.
This would include:
A-7

i. the selective payment default on a specific class or currency of debt;
ii. the uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation;
iii. the extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; ordinary execution of a distressed debt exchange on one or more material financial obligations.
D: Default.
'D' ratings indicate an issuer that in Fitch Ratings' opinion has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure or which has otherwise ceased business.
Default ratings are not assigned prospectively to entities or their obligations; within this context, non-payment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.
In all cases, the assignment of a default rating reflects the agency's opinion as to the most appropriate rating category consistent with the rest of its universe of ratings and may differ from the definition of default under the terms of an issuer's financial obligations or local commercial practice.
Notes
The modifiers + or - may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the 'AAA' Long-Term IDR category, or to Long-Term IDR categories below 'B'.
Fitch Short-Term Ratings Assigned to Issuers and Obligations
A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as "short term" based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets.
F1: Highest Short-Term Credit Quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.
F2: Good Short-Term Credit Quality. Good intrinsic capacity for timely payment of financial commitments.
F3: Fair Short-Term Credit Quality. The intrinsic capacity for timely payment of financial commitments is adequate.
B: Speculative Short-Term Credit Quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.
C: High Short-Term Default Risk. Default is a real possibility.
RD: Restricted Default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.
D: Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

APPENDIX E - PROXY POLICY AND PROCEDURES
Invesco’s Policy Statement on Global Corporate Governance and Proxy Voting
The Adviser and each sub-adviser rely on this policy. In addition, Invesco Asset Management (Japan) Limited and Invesco Asset Management (India) Pvt. Ltd. have also adopted operating guidelines and procedures for proxy voting particular to each regional investment center. Such guidelines and procedures are attached hereto.
E-1

Invesco’s Policy Statement on Global
Corporate Governance and
Proxy Voting
Effective January 2021
E-2

I.
INTRODUCTION
Invesco Ltd. and its affiliated investment advisers (collectively, “Invesco”, the “Company”, “our” or “we”) has adopted and implemented this Policy Statement on Global Corporate Governance and Proxy Voting (“Policy”) which it believes describes policies and procedures reasonably designed to ensure that proxies are voted in the best interests of its clients. This Policy is intended to help Invesco’s clients understand our commitment to responsible investing and proxy voting, as well as the good governance principles that inform our approach to engagement and voting at shareholder meetings.
A. Our Commitment to Environmental, Social and Governance Investment Stewardship and Proxy Voting
Our commitment to environmental, social and governance (ESG) principles is a core element of our ambition to be the most client centric asset manager. We aspire to incorporate ESG considerations into all of our investment capabilities in the context of financial materiality and in the best interest of our clients. Our Global ESG team functions as a center of excellence, providing specialist insights on research, engagement, voting, integration, tools, and client and product solutions with investment teams implementing ESG approaches appropriate to asset class and investment style. Much of our work is rooted in fundamental research and frequent dialogue with companies.
Invesco views proxy voting as an integral part of its investment management responsibilities. The proxy voting process at Invesco focuses on protecting clients’ rights and promoting governance structures and practices that reinforce the accountability of corporate management and boards of directors to shareholders. The voting decision lies with our portfolio managers and analysts with input and support from our Global ESG team and Proxy Operations functions. Our proprietary proxy voting platform (“PROXYintel”) facilitates implementation of voting decisions and rationales across global investment teams. Our good governance principles, governance structure and processes are designed to ensure that proxy votes are cast in accordance with clients’ best interests.
As a large active investor, Invesco is well placed to use our ESG expertise and beliefs to engage with portfolio companies in ways which drive corporate change that we believe will enhance shareholder value. We take our responsibility as active owners very seriously and see engagement as an opportunity to encourage continual improvement and ensure that our clients’ interests are represented and protected. Dialogue with portfolio companies is a core part of the investment process. Invesco may engage with investee companies to discuss environmental, social and governance issues throughout the year or on specific ballot items to be voted on.
Our passive strategies and certain other client accounts managed in accordance with fixed income, money market and index strategies (including exchange traded funds) will typically vote in line with the majority holder of the active-equity shares held by Invesco outside of those strategies. Invesco refers to this approach as “Majority Voting”. This process of Majority Voting ensures that our passive strategies benefit from the engagement and deep dialogue of our active investors, which Invesco believes benefits shareholders in passively-managed accounts. In the absence of overlap between the active and passive holders, the passive holders vote in line with our internally developed voting guidelines (as defined below). Portfolio managers and analysts for accounts employing Majority Voting retain full discretion to override Majority Voting and to vote the shares as they determine to be in the best interest of those accounts, absent certain types of conflicts of interest, which are discussed elsewhere in this Policy.
B. Applicability of Policy
Invesco may be granted by its clients the authority to vote the proxies of securities held in client portfolios. Invesco’s investment teams vote proxies on behalf of Invesco-sponsored funds and both fund and non-fund advisory clients that have explicitly granted Invesco authority in writing to vote proxies on their behalf. In the case of institutional or sub-advised clients, Invesco will vote the proxies in accordance with this Policy unless the client agreement specifies that the client retains the right to vote or has designated a named fiduciary to direct voting.
E-3

This Policy applies to all entities in Exhibit A. Due to regional or asset class specific considerations, there may be certain entities that have local proxy voting guidelines or policies and procedures that differ from this Policy. In the event that local policies and the Global Policy differ, the local policy will apply. These entities are also listed in Exhibit A and include proxy voting guidelines specific to; Invesco Asset Management (Japan) Limited, Invesco Asset Management (India) Pvt. Ltd, Invesco Taiwan Ltd and Invesco Capital Markets, Inc. for Invesco Unit Investment Trusts. In Europe, we comply with the Shareholder Rights Directive and publish our disclosures and voting practices in this regard.
II.
GLOBAL PROXY VOTING OPERATIONAL PROCEDURES
Invesco’s global proxy voting operational procedures are in place to implement the provisions of this Policy (the “Procedures”). At Invesco, proxy voting is conducted by our investment teams through PROXYintel. Our investment teams globally are supported by Invesco’s centralized team of ESG professionals and proxy voting specialists. Invesco’s Global ESG team oversees the proxy policy, operational procedures, inputs to analysis and research and leads the Global Invesco Proxy Advisory Committee (“Global IPAC”). Invesco’s global proxy administration team is responsible for operational implementation including vote execution oversight.
Invesco aims to vote all proxies where we have been granted voting authority in accordance with this Policy as implemented by the Procedures. Our portfolio managers and analysts review voting items based on their individual merits and retain full discretion on vote execution conducted through our proprietary proxy voting platform. Invesco may supplement its internal research with information from independent third-parties, such as proxy advisory firms.
A. Proprietary Proxy Voting Platform
Invesco’s proprietary proxy voting platform is supported by a dedicated team of internal proxy specialists. PROXYintel streamlines the proxy voting process by providing our investment teams globally with direct access to meeting information and proxies, external proxy research and ESG ratings, as well as related functions, such as management of conflicts of interest issues, significant votes, global reporting and record-keeping capabilities. Managing these processes internally, as opposed to relying on third parties, is designed to provide Invesco greater quality control, oversight and independence in the proxy administration process.
Historical proxy voting information is stored to build institutional knowledge across the Invesco complex with respect to individual companies and proxy issues. Certain investment teams also use PROXYintel to access third-party proxy research and ESG ratings.
Our proprietary systems facilitate internal control and oversight of the voting process. Invesco may choose to leverage this capability to automatically vote proxies based on its internally developed voting guidelines and in circumstances where Majority Voting applies.
B. Oversight of Voting Operations
Invesco’s Proxy Governance and Voting Manager provides oversight of the proxy voting verification processes facilitated by a dedicated proxy administration team which include; (i) the monthly global vote audit review of votes cast containing documented rationales of conflicts of interest votes, market and operational limitations; (ii) the quarterly sampling of proxy votes cast to determine that (a) Invesco is voting consistently with this Policy and (b) third-party proxy advisory firms’ methodologies in formulating the vote recommendation are consistent with their publicly disclosed guidelines; and (iii) quarterly review of rationales with the Global IPAC of occasions where a portfolio manager may take a position that may not be in accordance with Invesco’s good governance principles and our internally developed voting guidelines.
To the extent material errors are identified in the proxy voting process, such errors are reviewed and reported to, as appropriate, the Global Head of ESG, Global Proxy Governance and Voting Manager, legal and compliance, the Global IPAC and relevant boards and clients, where applicable. Invesco’s
E-4

Global Head of ESG and Proxy Governance and Voting Manager provide proxy voting updates and reporting to the Global IPAC, various boards and clients. Invesco’s proxy voting administration and operations are subject to periodic review by Internal Audit and Compliance groups.
C. Disclosures and Record Keeping
Unless otherwise required by local or regional requirements, Invesco maintains voting records in either electronic format or hard copy for at least 6 years. Invesco makes available its proxy voting records publicly in compliance with regulatory requirements and industry best practices in the regions below:
In accordance with the US Securities and Exchange Commission regulations, Invesco will file a record of all proxy voting activity for the prior 12 months ending June 30th for each U.S. registered fund. That filing is made on or before August 31st of each year. Each year, the proxy voting records are made available on Invesco’s website here. Moreover, and to the extent applicable, the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”), including Department of Labor regulations and guidance thereunder, provide that the named fiduciary generally should be able to review not only the investment manager's voting procedure with respect to plan-owned stock, but also to review the actions taken in individual proxy voting situations. In the case of institutional and sub-advised Clients, Clients may contact their client service representative to request information about how Invesco voted proxies on their behalf. Absent specific contractual guidelines, such requests may be made on a semi-annual basis.
In the UK and Europe, Invesco publicly discloses our proxy votes monthly in compliance with the UK Stewardship Code and for the European Shareholder Rights Directive annually here.
In Canada, Invesco publicly discloses our annual proxy votes each year here by August 31st, covering the 12-month period ending June 30th in compliance with the National Instrument 81-106 Investment Fund Continuous Disclosure.
In Japan, Invesco publicly discloses our proxy votes annually in compliance with the Japan Stewardship Code.
In India, Invesco publicly discloses our proxy votes quarterly in compliance with The Securities and Exchange Board of India (“SEBI”) Circular on stewardship code for all mutual funds and all categories of Alternative Investment Funds in relation to their investment in listed equities. SEBI has implemented principles on voting for Mutual Funds through circulars dated March 15, 2010 and March 24, 2014, which prescribed detailed mandatory requirements for Mutual Funds in India to disclose their voting policies and actual voting by Mutual Funds on different resolutions of investee companies.
In Hong Kong, Invesco Hong Kong Limited will provide proxy voting records upon request in compliance with the Securities and Futures Commission (“SFC”) Principles of Responsible Ownership.
In Taiwan, Invesco publicly discloses our proxy voting policy and proxy votes annually in compliance with Taiwan’s Stewardship Principles for Institutional Investors.
D. Global Invesco Proxy Advisory Committee
Guided by its philosophy that investment teams should manage proxy voting, Invesco has created the Global IPAC. The Global IPAC is an investments-driven committee comprised of representatives from various investment management teams globally, Invesco’s Global Head of ESG and chaired by its Global Proxy Governance and Voting Manager. The Global IPAC provides a forum for investment teams to monitor, understand and discuss key proxy issues and voting trends within the Invesco complex, to assist Invesco in meeting regulatory obligations, to review votes not aligned with our good governance principles and to consider conflicts of interest in the proxy voting process, all in accordance with this Policy.
E-5

In fulfilling its responsibilities, the Global IPAC meets as necessary, but no less than semi- annually, and has the following responsibilities and functions: (i) acts as a key liaison between the Global ESG team and local proxy voting practices to ensure compliance with this Policy; (ii) provides insight on market trends as it relates to stewardship practices; (iii) monitors proxy votes that present potential conflicts of interest; (iv) the Conflict of Interest sub-committee will make voting decisions on submissions made by portfolio managers on conflict of interest issues to override the Policy; and (v) reviews and provides input, at least annually, on this Policy and related internal procedures and recommends any changes to the Policy based on, but not limited to, Invesco’s experience, evolving industry practices, or developments in applicable laws or regulations.
In addition to the Global IPAC, for some clients, third parties (e.g., U.S. fund boards) provide oversight of the proxy voting process.
E. Market and Operational Limitations
In the great majority of instances, Invesco will vote proxies. However, in certain circumstances, Invesco may refrain from voting where the economic or other opportunity costs of voting exceeds any benefit to clients. Moreover, ERISA fiduciaries, in voting proxies or exercising other shareholder rights, must not subordinate the economic interests of plan participants and beneficiaries to unrelated objectives. These matters are left to the discretion of the relevant portfolio manager. Such circumstances could include, for example:
In some countries the exercise of voting rights imposes temporary transfer restrictions on the related securities (“share blocking”). Invesco generally refrains from voting proxies in share blocking countries unless Invesco determines that the benefit to the client(s) of voting a specific proxy outweighs the client’s temporary inability to sell the security.
Some companies require a representative to attend meetings in person to vote a proxy, additional documentation or the disclosure of beneficial owner details to vote. Invesco may determine that the costs of sending a representative, signing a power-of-attorney or submitting additional disclosures outweigh the benefit of voting a particular proxy.
Invesco may not receive proxy materials from the relevant fund or client custodian with sufficient time and information to make an informed independent voting decision.
Invesco held shares on the record date but has sold them prior to the meeting date.
In some non-U.S. jurisdictions, although Invesco uses reasonable efforts to vote a proxy, proxies may not be accepted or rejected due to changes in the agenda for a shareholder meeting for which Invesco does not have sufficient notice, a proxy voting service may not be offered by the custodian in the local market or due to operational issues experienced by third-parties involved in the process or by the issuer or sub-custodian. In addition, despite the best efforts of Invesco and its proxy voting agent, there may be instances where our votes may not be received or properly tabulated by an issuer or the issuer’s agent.
F. Securities Lending
Invesco’s funds may occasionally participate in a securities lending program. In circumstances where shares are on loan, the voting rights of those shares are transferred to the borrower. If the security in question is on loan as part of a securities lending program, Invesco may determine that the benefit to the client of voting a particular proxy outweighs the benefits of securities lending. In those instances, Invesco may determine to recall securities that are on loan prior to the meeting record date, so that we will be entitled to vote those shares. There may be instances where Invesco may be unable to recall shares or may choose not to recall shares. The relevant portfolio manager will make these determinations.
G. Conflicts of Interest
E-6

There may be occasions where voting proxies may present a perceived or actual conflict of interest between Invesco, as investment manager, and one or more of Invesco’s clients or vendors.
Firm-Level Conflicts of interest
A conflict of interest may exist if Invesco has a material business relationship with either the company soliciting a proxy or a third party that has a material interest in the outcome of a proxy vote or that is actively lobbying for a particular outcome of a proxy vote. Such relationships may include, among others, a client relationship, serving as a vendor whose products / services are material or significant to Invesco, serving as a distributor of Invesco’s products, a significant research provider or broker to Invesco.
Invesco identifies potential conflicts of interest based on a variety of factors, including but not limited to the materiality of the relationship between the issuer or its affiliates to Invesco.
Invesco’s proxy administration team maintains a list of all such issuers for which a conflict of interest exists (“Global Conflicts List”). Material firm-level conflicts of interests are identified by individuals and groups within Invesco globally based on criteria established by the proxy administration team. The Global Conflicts List is updated periodically by the proxy administration team so as to seek to ensure an updated view is available when conducting conflicts checks.
Operating procedures and associated governance are designed to seek to ensure conflicts of interest are appropriately considered ahead of voting proxies. The Global IPAC Conflict of Interest Sub-committee maintains oversight of the process. Companies on the Global Conflicts List will be voted in line with the principles below as implemented by Invesco’s internally developed voting guidelines. To the extent a portfolio manager disagrees with the Policy, our processes and procedures seek to ensure justification and rationales are fully documented and presented to the Global IPAC Sub-committee for a majority vote of its members.
As an additional safeguard, persons from Invesco’s marketing, distribution and other customer- facing functions may not serve on the Global IPAC. For the avoidance of doubt, Invesco may not consider Invesco Ltd.’s pecuniary interest when voting proxies on behalf of clients. To avoid any appearance of a conflict of interest, Invesco will not vote proxies issued by Invesco Ltd. that may be held in client accounts.
Personal Conflicts of Interest
A conflict also may exist where an Invesco employee has a known personal or business relationship with other proponents of proxy proposals, participants in proxy contests, corporate directors, or candidates for directorships. Under Invesco’s Global Code of Conduct, Invesco entities and individuals must act in the best interests of clients and must avoid any situation that gives rise to an actual or perceived conflict of interest.
All Invesco personnel with proxy voting responsibilities are required to report any known personal or business conflicts of interest regarding proxy issues with which they are involved. In such instances, the individual(s) with the conflict will be excluded from the decision-making process relating to such issues.
Voting Fund of Funds
There may be conflicts that can arise from Invesco voting on matters when shares of Invesco- sponsored funds are held by other Invesco funds or entities. The scenarios below set out how Invesco votes in these instances.
In the United States, as required by law, proportional voting applies.
Shares of an Invesco-sponsored fund held by other Invesco funds will be voted in the same proportion as the votes of external shareholders of the underlying fund, where required by law.
Shares of an unaffiliated registered fund held by one or more Invesco funds will be voted
E-7

in the same proportion as the votes of external shareholders of the underlying fund where the thresholds are met as required by federal securities law or any exemption therefrom.
To the extent proportional voting is required by law, but not operationally possible, Invesco will not vote the shares.
For US fund of funds where proportional voting is not required by law, Invesco will still apply proportional voting. In the event this is not operationally possible, Invesco will vote in line with our internally developed voting guidelines (as defined below).
For non-US fund of funds Invesco will vote in line with our above-mentioned firm-level conflicts of interest process unless we have local policies in place as per Exhibit A.
H. Use of Third-Party Proxy Advisory Services
Invesco may supplement its internal research with information from independent third-parties, such as proxy advisory firms. Globally, Invesco leverages research from Institutional Shareholder Services Inc. (“ISS”) and Glass Lewis (“GL”). Invesco generally retains full and independent discretion with respect to proxy voting decisions.
ISS and GL both provide research reports, including vote recommendations, to Invesco and its portfolio managers and analysts. Invesco retains ISS to provide recommendations based on Invesco’s internally developed custom guidelines. Updates to previously issued proxy research reports may be provided to incorporate newly available information or additional disclosure provided by the issuer regarding a matter to be voted on, or to correct factual errors which may result in the issuance of revised proxy vote recommendations. Invesco’s proxy administration team may periodically monitor for these research alerts issued by ISS and GL that are shared with our investment teams. There may be instances where these updates may not be provided in a timely manner ahead of the vote deadline.
Invesco also retains ISS to assist with services that include receipt of proxy ballots, vote execution through PROXYintel and vote disclosure in Canada, the UK and Europe to meet regulatory reporting obligations.
As part of its fiduciary obligation to clients, Invesco performs extensive initial and ongoing due diligence on the proxy advisory firms it engages globally. This includes reviews of information regarding the capabilities of their research staff, methodologies for formulating voting recommendations, the adequacy and quality of personnel and technology, as applicable, and internal controls, policies and procedures, including those relating to possible conflicts of interest.
The proxy advisory firms Invesco engages globally complete an annual due diligence questionnaire submitted by Invesco, and Invesco conducts annual due diligence meetings in part to discuss their responses to the questionnaire. In addition, Invesco monitors and communicates with these firms and monitors their compliance with Invesco’s performance and policy standards. ISS and GL disclose conflicts to Invesco through a review of their policies, procedures and practices regarding potential conflicts of interests (including inherent internal conflicts) as well as disclosure of the work ISS and GL perform for corporate issuers and the payments they receive from such issuers. Invesco conducts semi-annual roundtables with external proxy and governance experts and our Global IPAC to ensure transparency, dialogue and engagement with the firms. These meetings provide Invesco with an opportunity to assess the firms’ capabilities, conflicts of interest and service levels, as well as provide investment professionals with direct insight into the advisory firms’ stances on key governance and proxy topics and their policy framework/methodologies.
Invesco’s compliance function completes a review of the System and Organizational Controls (“SOC”) Reports for each proxy advisory firm to ensure the related controls operated effectively to provide reasonable assurance.
E-8

In addition to ISS and GL, Invesco may use regional third-party research providers to access regionally specific research.
I. Review of Policy
The Global IPAC and Invesco’s Global ESG team, proxy administration team, compliance and legal teams annually communicate and review this Policy and our internally developed voting guidelines to seek to ensure that they remain consistent with clients’ best interests, regulatory requirements, governance trends and industry best practices. At least annually, this Policy and our internally developed voting guidelines are reviewed by various groups within Invesco to ensure that they remain consistent with Invesco’s views on best practice in corporate governance and long-term investment stewardship.
III.
OUR GOOD GOVERNANCE PRINCIPLES
Invesco’s good governance principles outline our views on best practice in corporate governance and long-term investment stewardship. These principles have been developed by our global investment teams in collaboration with the Global ESG team. The broad philosophy and guiding principles in this section inform our approach to investment stewardship and proxy voting. These principles are not intended to be exhaustive or prescriptive.
Our portfolio managers and analysts retain full discretion on vote execution except where otherwise specified in this Policy. The final voting decisions may incorporate the unique circumstances affecting companies, regional best practices and any dialogue we have had with company management. To the extent a portfolio manager chooses to vote a proxy in a way that is not aligned with the principles below, such manager’s rationales are fully documented.
The following guiding principles apply to operating companies. We apply a separate approach to investment companies and unit investment trusts. Where appropriate, these guidelines are supplemented by additional internal guidance that considers regional variations in best practices, disclosure and region-specific voting items.
The following are high-level governance principles that Invesco endorses:
A. Transparency
Investors require accurate, timely and complete information in order to make informed investment decisions and effectively carry out their stewardship obligations. Invesco supports the highest standards in corporate transparency, including but not limited to the following areas:
Financial reporting: Company accounts and reporting must accurately reflect the underlying economic position of a company. Arrangements that may constitute an actual or perceived conflict with this objective should be avoided.
We will generally vote against the incumbent audit committee chair, or nearest equivalent, where the non-audit fees paid to the independent auditor exceed audit fees for two consecutive years or other problematic accounting practices are identified such as fraud, misapplication of audit standards or persistent material weaknesses/deficiencies in internal controls over financial reporting.
We will generally not support the ratification of the independent auditor and/or ratification of their fees payable if non-audit fees exceed audit and audit related fees or there are significant auditing controversies or questions regarding the independence of the external auditor. We will consider an auditor’s length of service as a company’s independent auditor in applying this policy.
B. Accountability
Robust shareholder rights and strong board oversight help ensure that management adhere to the highest standards of ethical conduct, are held to account for poor performance and responsibly deliver
E-9

value creation for stakeholders over the long-term. We therefore encourage companies to adopt governance features that ensure board and management accountability. In particular, we consider the following as key mechanisms for enhancing accountability to investors:
One share one vote: Voting rights are an important tool for investors to hold boards and management teams accountable. Unequal voting rights may limit the ability of investors to exercise their stewardship obligations.
We generally do not support proposals that establish or perpetuate dual classes of voting shares, double voting rights or other means of differentiated voting or disproportionate board nomination rights.
We generally support proposals to decommission differentiated voting rights.
Where unequal voting rights are established, we expect these to be accompanied by reasonable safeguards to protect minority shareholders’ interests.
Anti-takeover devices: Mechanisms designed to prevent or unduly delay takeover attempts may unduly limit the accountability of boards and management teams to shareholders.
We generally will not support proposals to adopt antitakeover devices such as poison pills. Exceptions may be warranted at entities without significant operations and to preserve the value of net operating losses carried forward or where the applicability of the pill is limited in scope and duration.
In addition, we will generally not support capital authorizations or amendments to corporate articles or bylaws at operating companies that may be utilized for antitakeover purposes, for example, the authorization of classes of shares of preferred stock with unspecified voting, dividend, conversion or other rights (“blank check” authorizations).
Shareholder rights: We support the rights of shareholders to hold boards and management teams accountable for company performance. We generally support best practice aligned proposals to enhance shareholder rights, including but not limited to the following:
Adoption of proxy access rights
Rights to call special meetings
Rights to act by written consent
Reduce supermajority vote requirements
Remove antitakeover provisions
Requirement that directors are elected by a majority vote
In addition, we oppose practices that limit shareholders’ ability to express their views at a general meeting such as bundling unrelated proposals or several significant article or bylaw amendments into a single voting item. We will generally vote against these proposals unless we are satisfied that all the underlying components are aligned with our views on best practice.
Director Indemnification: Invesco recognizes that individuals may be reluctant to serve as corporate directors if they are personally liable for all related lawsuits and legal costs. As a result, reasonable limitations on directors’ liability can benefit a company and its shareholders by helping to attract and retain qualified directors while preserving recourse for shareholders in the event of misconduct by directors. Accordingly, unless there is insufficient information to make a decision about the nature of the proposal, Invesco will generally support proposals to limit directors’ liability and provide indemnification and/or exculpation, provided that the arrangements are reasonably limited in scope to directors acting in good faith and, in relation to criminal matters, limited in scope to directors having reasonable grounds for believing the conduct was lawful.
E-10

Responsiveness: Boards should respond to investor concerns in a timely fashion, including reasonable requests to engage with company representatives regarding such concerns, and address matters that receive significant voting dissent at general meetings of shareholders.
We will generally vote against the lead independent director and/or the incumbent chair of the governance committee, or nearest equivalent, in cases where the board has not adequately responded to items receiving significant voting opposition from shareholders at an annual or extraordinary general meeting.
We will generally vote against the lead independent director and/or incumbent chair of the governance committee, or nearest equivalent, where the board has not adequately responded to a shareholder proposal which has received significant support from shareholders.
We will generally vote against the incumbent chair of the compensation committee if there are significant ongoing concerns with a company’s compensation practices that have not been addressed by the committee or egregious concerns with the company’s compensation practices for two years consecutively.
In addition, we will generally vote against the incumbent compensation committee chair where there are ongoing concerns with a company’s compensation practices and there is no opportunity to express dissatisfaction by voting against an advisory vote on executive compensation, remuneration report (or policy) or nearest equivalent.
C. Board Composition
Annual director elections: Board members should generally stand for election annually and individually.
We will generally support proposals requesting that directors stand for election annually.
We will generally vote against the incumbent governance committee chair or lead independent director if a company has a declassified board structure that is not being phased out. This policy will not apply in regions where market practice is for directors to stand for election on a staggered basis or for boards that do not oversee significant commercial operations.
When a board is presented for election as a slate (i.e., shareholders are unable to vote against individual nominees and must vote for or against the entire nominated slate of directors) and this approach is not aligned with local market practice, we will generally vote against the slate in cases where we otherwise would vote against an individual nominee.
Where market practice is to elect directors as a slate we will generally support the nominated slate unless there are governance concerns with several of the individuals included on the slate or we have broad concerns with the composition of the board such as a lack independence.
Board size: We will generally defer to the board with respect to determining the optimal number of board members, provided that the proposed board size is sufficiently large to represent shareholder interests and sufficiently limited to remain effective.
Definition of independence: Invesco considers local market definitions of director independence but applies a proprietary standard for assessing director independence considering a director’s status as a current or former employee of the business, any commercial or consulting relationships with the company, the level of shares beneficially owned or represented and familial relationships, among others.
Board and committee independence: The board of directors, board committees and regional equivalents should be sufficiently independent from management, substantial shareholders and conflicts of interest. We consider local market practices in this regard and in general we look for a balance across the board of directors. Above all, we like to see signs of robust challenge and discussion in the boardroom.
We will generally vote against one or more non-independent directors when a board is less than
E-11

majority independent, but we will take into account local market practice with regards to board independence in limited circumstances where this standard is not appropriate.
We will generally vote against non-independent directors serving on the audit committee.
We will generally vote against non-independent directors serving on the compensation committee.
We will generally vote against non-independent directors serving on the nominating committee.
In relation to the board, compensation committee and nominating committee we will consider the appropriateness of significant shareholder representation in applying this policy. This exception will generally not apply to the audit committee.
Separation of Chair and CEO roles: We believe that independent board leadership generally enhances management accountability to investors. Companies deviating from this best practice should provide a strong justification and establish safeguards to ensure that there is independent oversight of a board’s activities (e.g., by appointing a lead or senior independent director with clearly defined powers and responsibilities).
We will generally vote against the incumbent nominating committee chair where the board chair is not independent unless a lead independent or senior director is appointed.
We will generally support shareholder proposals requesting that the board chair be an independent director.
We will generally not vote against a CEO or executive serving as board chair solely on the basis of this issue, however, we may do so in instances where we have significant concerns regarding a company’s corporate governance, capital allocation decisions and/or compensation practices.
Attendance and over boarding: Directors serving on the board should attend at least 75% of their board and committee meetings, where applicable. In addition, directors should not have excessive external board or managerial commitments that may interfere with their ability to execute the duties of a director.
We will generally vote against directors who do not attend 75% of their meetings unless there are extenuating circumstances such as health matters or family emergencies.
We will generally vote against directors who have more than four total mandates at public operating companies. We apply a lower threshold for directors with significant commitments such as executive positions and chairmanships.
Diversity: We encourage companies to continue to evolve diversity and inclusion practices. Boards should be comprised of directors with a variety of relevant skills and industry expertise together with a diverse profile of individuals of different genders, ethnicities, skills, tenures and backgrounds in order to provide robust challenge and debate. We consider diversity at the board level, within the executive management team and in the succession pipeline.
We will generally vote against the incumbent nominating committee chair of a board where women constitute less than two board members or 25% of the board, whichever is lower, for two or more consecutive years, unless incremental improvements are being made to diversity practices.
In addition, we will consider a company’s performance on broader types of diversity which may include diversity of skills, non-executive director tenure, ethnicity or other factors where appropriate and reasonably determinable. We will generally vote against the incumbent nominating committee chair if there are multiple concerns on diversity issues.
We generally believe that an individual board’s nominating committee is best positioned to determine whether director term limits would be an appropriate measure to help achieve these
E-12

goals and, if so, the nature of such limits. Invesco generally opposes proposals to limit the tenure of outside directors through mandatory retirement ages.
D. Long Term Stewardship of Capital
Capital allocation: Invesco expects companies to responsibly raise and deploy capital towards the long-term, sustainable success of the business. In addition, we expect capital allocation authorizations and decisions to be made with due regard to shareholder dilution, rights of shareholders to ratify significant corporate actions and pre-emptive rights, where applicable.
Share issuance and repurchase authorizations: We generally support authorizations to issue shares up to 20% of a company’s issued share capital for general corporate purposes. Shares should not be issued at a substantial discount to the market price or be repurchased at a substantial premium to the market price.
Stock splits: We generally support management proposals to implement a forward or reverse stock split, provided that a reverse stock split is not being used to take a company private. In addition, we will generally support requests to increase a company’s common stock authorization if requested in order to facilitate a stock split.
Increases in authorized share capital: We will generally support proposals to increase a company’s number of authorized common and/or preferred shares, provided we have not identified concerns regarding a company’s historical share issuance activity or the potential to use these authorizations for antitakeover purposes. We will consider the amount of the request in relation to the company’s current authorized share capital, any proposed corporate transactions contingent on approval of these requests and the cumulative impact on a company’s authorized share capital, for example, if a reverse stock split is concurrently submitted for shareholder consideration.
Mergers, acquisitions, proxy contests, disposals and other corporate transactions: Invesco’s investment teams will review proposed corporate transactions including mergers, acquisitions, reorganizations, proxy contests, private placements, dissolutions and divestitures based on a proposal’s individual investment merits. In addition, we broadly approach voting on other corporate transactions as follows:
We will generally support proposals to approve different types of restructurings that provide the necessary financing to save the company from involuntary bankruptcy.
We will generally support proposals to enact corporate name changes and other proposals related to corporate transactions that we believe are in shareholders’ best interests.
We will generally support reincorporation proposals, provided that management have provided a compelling rationale for the change in legal jurisdiction and provided further that the proposal will not significantly adversely impact shareholders’ rights.
With respect to contested director elections, we consider the following factors, among others, when evaluating the merits of each list of nominees: the long term performance of the company relative to its industry, management’s track record, any relevant background information related to the contest, the qualifications of the respective lists of director nominees, the strategic merits of the approaches proposed by both sides including the likelihood that the proposed goals can be met, positions of stock ownership in the company.
E. Environmental, Social and Governance Risk Oversight
Director responsibility for risk oversight: The board of directors are ultimately responsible for overseeing management and ensuring that proper governance, oversight and control mechanisms are in place at the companies they oversee. Invesco may take voting action against director nominees in response to material governance or risk oversight failures that adversely affect shareholder value.
E-13

Invesco considers the adequacy of a company's response to material oversight failures when determining whether any voting action is warranted. In addition, Invesco will consider the responsibilities delegated to board subcommittees when determining if it is appropriate to hold certain director nominees accountable for these material failures.
Material governance or risk oversight failures at a company may include, without limitation:
i. significant bribery, corruption or ethics violations;
ii. events causing significant environmental degradation;
iii. significant health and safety incidents; or
iv. failure to ensure the protection of human rights.
Reporting of financially material ESG information: Companies should report on their environmental, social and governance opportunities and risks where material to their business operations.
Where Invesco finds significant gaps in terms of management and disclosure of environmental, social and governance risk policies, we will generally vote against the annual reporting and accounts or an equivalent resolution.
Shareholder proposals addressing environmental and social risks: Invesco may support shareholder resolutions requesting that specific actions be taken to address environmental and social issues or mitigate exposure to material environmental and social risks, including reputational risk, related to these issues. When considering such proposals, we will consider a company's track record managing these risks, the efficacy of the proposal's request and whether the requested action is unduly burdensome.
We generally do not support resolutions where insufficient information has been provided in advance of the vote or a lack of disclosure inhibits our ability to make fully informed voting decisions.
We will generally support shareholder resolutions requesting that companies provide additional information on material environmental, social and governance risks facing their businesses, provided that such requests are not unduly burdensome or duplicative with a company’s existing reporting. These may include but are not limited to the following: gender pay gap reporting requests, political contributions and lobbying disclosure, information on data security, privacy, and internet practices, and reporting on climate change risks.
Ratification of board and/or management acts: We will generally support proposals to ratify the actions of the board of directors, supervisory board and/or executive decision-making bodies, provided there are no material oversight failures as described above. When such oversight concerns are identified, we will consider a company’s response to any issues raised and may vote against ratification proposals instead of, or in addition to, director nominees.
F. Executive Compensation and Alignment
Invesco supports compensation polices and equity incentive plans that promote alignment between management incentives and shareholders’ long-term interests. We pay close attention to local market practice and may apply stricter or modified criteria where appropriate.
Advisory votes on executive compensation, remuneration policy and remuneration reports: We will generally not support compensation related proposals where more than one of the following is present:
i. there is an unmitigated misalignment between executive pay and company performance for at least two consecutive years;
ii. there are problematic compensation practices which may include among others incentivizing excessive risk taking or circumventing alignment between management and shareholders’ interests via repricing of underwater options;
E-14

iii. vesting periods for long term incentive awards are less than three years;
iv. the company “front loads” equity awards;
v. there are inadequate risk mitigating features in the program such as clawback provisions;
vi. excessive, discretionary one-time equity grants are awarded to executives;
vii. less than half of variable pay is linked to performance targets, except where prohibited by law.
Invesco will consider company reporting on pay ratios as part of our evaluation of compensation proposals, where relevant.
Equity plans: Invesco generally supports equity compensation plans that promote the proper alignment of incentives with shareholders’ long-term interests, and generally votes against plans that are overly dilutive to existing shareholders, plans that contain objectionable structural features which may include provisions to reprice options without shareholder approval, plans that include evergreen provisions or plans that provide for automatic accelerated vesting upon a change in control.
Employee stock purchase plans: We generally support employee stock purchase plans that are reasonably designed to provide proper incentives to a broad base of employees, provided that the price at which employees may acquire stock represents a reasonable discount from the market price.
Severance Arrangements: Invesco considers proposed severance arrangements (sometimes known as “golden parachute” arrangements) on a case-by-case basis due to the wide variety among their terms. Invesco acknowledges that in some cases such arrangements, if reasonable, may be in shareholders’ best interests as a method of attracting and retaining high quality executive talent. We generally vote in favor of proposals requiring shareholder ratification of senior executives’ severance agreements where the proposed terms and disclosure align with good market practice.

We vote proxies for the purpose of seeking to maximize the interests of our clients (investors) and beneficiaries over time, acknowledging the importance of corporate governance, based on fiduciary duties to our clients (investors) and beneficiaries. We do not vote proxies for the interests of ourselves and any third party other than clients (investors) and beneficiaries. The interests of clients (investors) and beneficiaries is to expand the corporate value or the economic interest of shareholders or the preventing of damage thereto. . Proxy voting is an integral part of our stewardship activities and we make voting decisions considering whether or not the proposal would contribute to the corporate value expansion and sustainable growth.
In order to vote proxies adequately we have established the Responsible Investment Committee and developed these Proxy Voting Guidelines to oversee control of the decision making process concerning proxy voting. While we may seek advice from an external service provider based on our own guidelines, our investment professionals make voting decisions in principle, based on our proxy voting guidelines, taking into account whether or not they contribute to shareholder value enhancement of the subject company.
Responsible proxy voting and constructive dialogue with investee companies are important components of stewardship activities. While the proxy voting guidelines are principles for our making voting decisions, depending on the proposals, we may make special decisions to maximize the interests of clients (investors) and beneficiaries, through the establishment of constructive dialogue with the investee companies. In such case, approval of the Responsible Investment Committee shall be obtained.
The Responsible Investment Committee is consisted of members including Director in charge of the Investment Division as the chair, Head of Compliance, Responsible Investment Officer, investment professionals nominated by the chair and persons in charge at the Client Reporting Department.
We have developed the Conflict of Interest Control Policy and, even in the situation where any conflict of interest is likely to arise, we work to control conflict of interest to protect the interests of clients (investors) and beneficiaries. The Compliance Department is responsible for overseeing company-wide control of conflict of interest. The Compliance Department is independent from investment and marketing divisions, and shall not receive any command or order with respect to the matters concerning compliance with the laws and regulations including the matters concerning conflict of interest from investment and marketing divisions.
Proxy Voting Guidelines
1. Profit Allocation and Dividends
We decide how to vote on the proposals seeking approval for profit allocation and dividends, taking into account the financial conditions and business performance of the subject company, and the economic interest of shareholders, etc.
Taking into account the status of capital adequacy and business strategies, etc. of the subject company, if the total payout ratio including dividends and share buybacks is significantly low, we consider to vote against the proposals, unless reasonable explanation is given by the company.
With respect to the company where profit allocation is determined by the board of directors, taking into account the status of capital adequacy and business strategies, etc. of the subject company, if the total payout ratio including dividends and share buybacks is significantly low, we consider to vote against reelection of directors, unless reasonable explanation is given by the company.
Taking into account the status of capital adequacy and business strategies, etc. of the subject company, if the total payout ratio including dividends and share buybacks is significantly low, we consider to vote for the shareholder proposals that require more payout to shareholders.
2. Election of Directors
We decide how to vote on the proposals concerning election of directors, taking into account independence, competence and existence of anti-social acts of director candidates, etc. We decide how to vote on reelection of director candidates, taking into account their approach to corporate governance and
E-18

accountability during their tenure, business performance of the company and existence of anti-social acts of the company, etc. in addition to the above factors.
Directors should make efforts to continuously gain knowledge and skills from time to time to fulfill the important role and responsibilities in governance of the subject company. Companies are also required to provide sufficient opportunities of such training.
Independent outside directors are expected to play a significant role such as to secure the interest of minority shareholders through activities based on their insights to increase the corporate value of the subject company. It is desirable to enhance the board's governance function with independent outside directors accounting for the majority of the board. However, given the challenge to secure competent candidates, we also recognize that, under the current conditions, it is difficult for all the companies, irrespective of their size, to deploy a majority of the board with independent outside directors.
(1)
Independence
We generally vote for election of outside directors; provided, however, that we generally vote against the candidate who is not regarded as independent from the subject company. With respect to independence, it is desirable that the subject company discloses numerical standard which should support our decision.
We view following candidates for outside directors are not enough independent;
Candidates who have been working for following companies during the last 10 years or relatives of those people.
The subject company
Subsidiary of the subject company
Parent of the subject company
Candidates who have been working for following companies during the last five years or relatives of those people.
Shareholders who own more than 10% of the subject company
Principal loan lender
Principal securities broker
Major business relationship
Auditor of the subject company
Audit companies, consulting companies or any related service providers which have any consulting contracts with the subject company
Any other counterparts which have any interests in the subject company
We further scrutinize the independence of candidates who are regarded as not independent enough, even though those are not categorized the case listed above.
We carefully consider the independence of the candidates who are regarded as being in the cross-share-holding relationship, or the relationship in which companies are sending outside directors each other. We expect that the company should disclose the detail information related to the independence of those candidates reasonably, to enable investors to understand those relationships enough, both in terms of the disclosure timing and method.
We judge independence based on the independence criteria stipulated by the stock exchange, with focus on whether independence is substantially secured. We consider each company’s
E-19

business surroundings and make best effort to have constructive dialogue with the subject company to understand the independence of the candidates.
We regard the outside director with significantly long tenure as non-independent, and vote against reelection of such outside director. We generally consider voting against the candidate whose tenure is longer than 10 years.
In the case where the subject company is the company with a board with audit committee structure, we judge independence of outside director candidates who become members of the audit committee based on the same independence criteria for election of statutory auditors in principle.
In the case where the subject company is the company with a three committee board structure or the company with a board with audit committee structure, we generally consider to vote against the director candidates who are top executives of the subject company, if independent outside directors of the subject company account for less than 1/3 of the board after the shareholders meeting.
In the case where the subject company is the company with a statutory auditor structure, we generally vote against the director candidates who are top executives, unless there are at least two outside directors who are independent from the subject company after the shareholders meeting.
In the case where the subject company has a parent company, we generally consider voting against the director candidates who are top executives of the subject company, if outside directors who are independent from the subject company account for less than half of the board after the shareholders meeting.
(2)
Attendance rate and concurrent duties
All members are expected to attend the board meetings and each committee in principle, and companies are generally obligated to facilitate all members to attend meetings. We generally vote against reelection of the director candidate who attended less than 75% of the board meetings or the respective committee.
We take into account not only the number of attendance but reasons for nomination and substantial contribution, if disclosed.
We carefully consider the quality of the candidates who have many concurrent duties as outside directors or outside auditors of listed companies, given that outside directors/auditors are expected to make an important contribution to the board discussion. The company which nominates the candidates who have many concurrent duties should explain the reasonable background and eligibility for such nomination and make best effort to enable investors to understand them enough, both in terms of the disclosure timing and method.
(3)
Business performance of the company
We consider voting against reelection of director candidates, if the subject company made a loss for the three-consecutive year during their tenure.
We consider voting against reelection of director candidates, if it is judged that the business performance of the subject company is significantly behind peers in the same industry during their tenure.
We consider voting against the directors who are top executives, if business strategies that enable the corporate value enhancement and sustainable growth are not demonstrated and no constructive dialogue is conducted, with respect to capital efficiency including return on capital.
(4)
Anti-social acts of the company
If it is judged that there has been any corporate scandal that has significant social effects and has impaired, or is likely to impair, the shareholder value during the tenure, we shall conduct sufficient
E-20

dialogue with the subject company on the background and subsequent resolutions of the scandal. Based on the dialogue and taking into account impact on the shareholder value, we decide how to vote on reelection of the director candidates who are top executives, directors in charge of those cases and members of the audit committee or the similar committee.
With respect to domestic scandals, if the company has received administrative disposition on cartel or bid-rigging, we consider voting against reelection of the director candidates who are top executives, directors in charge and members of the audit committee or the similar committee, at the time when the disposition is determined by the Fair Trade Commission, etc. If the final disposition is subsequently determined on appeal or complaint, we do not vote against reelection again at such time. We decide case-by-case with respect to an order for compensation in a civil case or disposition by the Consumer Affairs Agency and administrative disposition imposed overseas.
With respect to administrative disposition imposed on a subsidiary or affiliate, if the subsidiary or affiliate is unlisted, we consider voting against reelection of the director candidates who are top executives, directors in charge and members of the audit committee or the similar committee of the holding company or the parent company. If the subsidiary or affiliate is listed, we consider to vote against reelection of the director candidates who are top executives, directors in charge and members of the audit committee or the similar committee of the subsidiary or affiliate and the parent company; provided, however, that we decide case-by-case depending on importance of the disposition on the subsidiary or affiliate, its impact on business performance of the holding company or parent company.
With respect to a scandal of an individual employee, if such scandal has impaired, or is likely to impair the shareholder value, and it is judged that the subject company should assume responsibility as a manager, we consider to vote against reelection of the director candidates who are top executives, directors in charge and members of the audit committee or the similar committee.
We consider voting against reelection of director candidates, if the subject company has committed window-dressing and inadequate accounting activities during their tenure.
(5)
Acts against the interest of shareholders
If the company has increased capital through a third-party allotment that is excessively dilutive without resolution by the shareholders meeting, we consider to vote against reelection of director candidates, particularly the director candidates who are top executives.
If the company has increased capital through a large-scale public offering without reasonable explanation, we consider voting against reelection of director candidates, particularly the director candidates who are top executives.
If the shareholder proposal that is judged desirable for minority shareholders has received the majority support, but the company does not implement such proposal or make the similar proposal as the company proposal at the shareholders meeting in the following year, we consider voting against the director candidates who are top executives.
(6)
Other
If information of a director candidate is not fully disclosed, we generally vote against such director candidate.
3. Composition of Board of Directors, etc.
Depending on the size of companies, etc., we believe that a three-committee board structure is desirable to achieve better governance as a listed company. Even for a company with a statutory auditor structure or a company with a board with audit committee, it is also desirable to voluntarily deploy the nomination
E-21

committee, compensation committee and other necessary committees. It is also desirable that the chair of the board of directors is an independent outside director. We believe that composition of the highly transparent board of directors secures transparency of the management and contributes to a persistent increase in the enterprise value. It is also desirable that the third-party assessment of the board of directors is disclosed.
We are concerned about the retired director assuming a consulting, advisory or other similar position which is likely to have negative impact on greater transparency and decision making of the board of directors. If such position or a person assuming such position exists, it is desirable that its existence, expected role and effects or compensation and other treatment for such position are fully disclosed.
(1)
Number of members and change in constituents of the board of directors
We decide how to vote on the proposals concerning the number of members and change in constituents of the board of directors, by comparing with the current structure and taking into account impact on the subject company and the economic interest of shareholders.
Number of the board member should be well optimized to make the right management decision at the right timing. We may take into consideration each company’s business situation and business scale; however we generally consider to vote against the director candidates who are top executives, in the case that the number of board member exceeds 20 and is not decreased from the previous shareholder’s meeting and also the reason for such case is not enough disclosed and reasonably explained.
We generally vote against the director candidates who are top executives in the case that the percentage of outside directors declines substantially through the decrease of outside directors or the increase of internal directors.
(2)
Procedures for election of directors, scope of responsibilities of directors, etc.
We decide how to vote on the proposals concerning a change in procedures for election of directors, by comparing with the current procedures and taking into account reasonableness of such change, etc.
We generally vote against the proposals that reduce responsibility of directors for monetary damages due to their breach of duty of care of a prudent manager.
Responsibilities of the board of directors include proper supervision over the succession plan for top executives. The nomination committee at the company with a three-committee board structure, or the nomination committee that should be voluntarily deployed by the company with a different structure, should provide proper supervision over fostering and election of successors with secured transparency. It is desirable that an independent outside director serves as the chair of the nomination committee. If the process is judged to significantly lack transparency and reasonableness, we consider to vote against the director candidates who are top executives.
4. Election of Statutory Auditors
We decide how to vote on the proposals concerning election of statutory auditors, taking into account independence, competence and existence of anti-social acts of auditor candidates, etc. We decide how to vote on reelection of statutory auditor candidates, taking into account their approach to corporate governance and accountability during their tenure, existence of anti-social acts of the company, etc. in addition to the above factors.
Statutory auditors and directors who are members of the audit committee or the similar committee are required to have deep specialized knowledge of accounting and laws and regulations, and should make efforts to continuously gain knowledge and skills from time to time to fulfill the important role and responsibilities in governance of the subject company. Companies are also required to provide sufficient opportunities of such training.
E-22

(1)
Independence
We generally vote against non-independent outside statutory auditors.
The person who has no relationship with the subject company other than being elected as a statutory auditor is regarded as independent.
We regard the outside statutory auditor with significantly long tenure as non-independent, and vote against reelection of such outside statutory auditor. We generally consider to vote against the candidate whose tenure is longer than 10 years.
(2)
Attendance rate and concurrent duties
All statutory auditors are expected to attend meetings of the board of directors or the board of statutory auditors in principle, and companies are generally obligated to facilitate all statutory auditors to attend meetings. We generally vote against reelection of the statutory auditor candidate who attended less than 75% of meetings of the board of directors or the board of statutory auditors.
We take into account not only the number of attendance but reasons for nomination and substantial contribution, if disclosed.
We carefully consider the quality of the candidates who have many concurrent duties as outside directors or outside auditors of listed companies, given that outside directors/auditors are expected to make an important contribution to the board discussion. The company which nominate the candidates who have many concurrent duties should explain the reasonable background and eligibility for such nomination and make best effort to enable investors to understand them enough, both in terms of the disclosure timing and method.
(3)
Accountability
If there are material concerns about the provided auditor report or auditing procedures, or if the matters to be disclosed are not fully disclosed, we vote against reelection of statutory auditor candidates.
(4)
Anti-social acts of the company
If it is judged that there has been any corporate scandal that has significant social effects and has impaired, or is likely to impair, the shareholder value during the tenure, we shall conduct sufficient engagement with the subject company on the background and subsequent resolutions of the scandal. Based on the engagement and taking into account impact on the shareholder value, we decide how to vote on reelection of statutory auditor candidates.
With respect to domestic scandals, if the company has received administrative disposition on cartel or bid-rigging, we consider to vote against reelection of statutory auditor candidates, at the time when the disposition is determined by the Fair Trade Commission, etc. If the final disposition is subsequently determined on appeal or complaint, we do not vote against reelection again at such time. We decide case-by-case with respect to an order for compensation in a civil case or disposition by the Consumer Affairs Agency and administrative disposition imposed overseas.
With respect to administrative disposition imposed on a subsidiary or affiliate, if the subsidiary or affiliate is unlisted, we consider to vote against reelection of statutory auditor candidates of the holding company or the parent company. If the subsidiary or affiliate is listed, we consider to vote against reelection of statutory auditor candidates of the subsidiary or affiliate and the holding company; provided, however, that we decide case-by-case depending on importance of the disposition on the subsidiary or affiliate, its impact on business performance of the holding company or parent company.
With respect to a scandal of an individual employee, if such scandal has impaired, or is likely to
E-23

impair the shareholder value, and it is judged that the subject company should assume responsibility as a manager, we consider to vote against reelection of statutory auditor candidates.
We consider voting against reelection of statutory auditor candidates, if the subject company has committed window-dressing and inadequate accounting activities during their tenure.
5. Composition of Board of Statutory Auditors
We decide how to vote on the proposals concerning the number of members and change in constituents of the board of statutory auditors, by comparing with the current structure and taking into account impact on the subject company and the economic interest of shareholders.
We favorably consider an increase in the number of statutory auditors, but in the case of a decrease in the number of statutory auditors, unless reasons are clearly and reasonably stated, we consider to vote against reelection of the director candidates who are top executives.
6. Election and Removal of Accounting Auditors
We decide how to vote on the proposals concerning election and removal of accounting auditors, taking into account competence of candidates and the level of costs for the accounting audit, etc.
If it is judged that there are following problems with the accounting audit services in the subject company, and the accounting auditor in question is not removed but reelected, we generally vote against reelection of the statutory auditor candidates and the director candidates who are members of the audit committee or the similar committee:
It is judged that the accounting auditor has expressed incorrect opinions on financial conditions;
In the case where there are concerns on the financial statements, the matters to be disclosed are not fully disclosed;
In the case where the accounting auditor has a contract of non-accounting audit services with the subject company, it is judged that such non-accounting audit services are recognized to have conflict of interest with accounting audit services;
In the case where excessive accounting audit costs are paid;
It is judged that gross fraudulence or negligence of the accounting auditor is recognized.
If it is judged that there are problems with accounting audit services in another company, and the accounting auditor in question becomes a candidate for election or is not removed but reelected, we decide how to vote, giving full consideration to impact on the enterprise value of the subject company.
We generally vote against the proposals concerning a change in accounting auditors, if difference in views about the accounting principles between the previous accounting auditor and the subject company is judged to be the reason for such change.
7. Compensation and Bonuses for Directors, Statutory Auditors and Employees
(1)
Compensation and bonuses for Directors
In determining compensation and bonuses for directors, it is desirable to increase the proportion of stocks in compensation and bonuses, taking into account whether the performance-based compensation structure is developed, whether transparency is fully secured such as disclosure of an index or formula as a basis for calculation, and impact on shareholders such as dilution. The compensation committee at the company with a three-committee board structure, or the compensation committee that should be voluntarily deployed by the company with a different
E-24

structure, should ensure the compensation structure with secured transparency. It is desirable that an independent outside director serves as the chair of the compensation committee.
We consider to vote against the proposals seeking approval for compensation and bonuses in the following cases:
where negative correlation is seen between the business performance of the subject company and compensation and bonuses;
where there exist problematic system and practices;
where the aggregate amount of compensation and bonuses is not disclosed;
where mismanagement is clear as shown by share price erosion or and significant deterioration in profit;
where the person who is judged to be responsible for acts against the interest of shareholders is among recipients of compensation and bonuses.
We generally vote for the proposals requesting disclosure of compensation and bonuses of individual directors.
If any measures are implemented to secure transparency of the system other than individual disclosure, such measures are taken into account.
If there is no proposal seeking approval for compensation and bonuses and the system is not clear, we consider to vote against election of the director candidates who are top executives,
We generally vote against bonuses for statutory auditors and the directors who become members of the audit committee under the audit committee system
As directors who become members of the audit committee at the company with a three committee structure, directors who become members of the audit committee at the company with a board with audit committee structure and outside directors are required to perform duties as director, we consider their compensation and bonuses differently from statutory auditors at the company with a statutory auditor structure.
(2)
Stock compensation
We decide how to vote on the proposals concerning stock compensation including stock option plans and restricted stock units, taking into account impact on the shareholder value and rights of shareholders, the level of compensation, the recipients of stock compensation, and reasonableness, etc.
We generally vote against the proposals seeking to lower the strike price of stock options.
We generally vote for the proposals seeking to require approval of shareholders for change in the strike price of stock options.
We generally vote against the stock compensation, if terms of exercise including the percentage of dilution are unclear. We generally consider to vote against the proposal in which there is a 10% or more dilution potentiality.
Stock compensation should be a long-term incentive and its plan should be aligned with a long-term corporate value growth. Considering that, we generally vote against the proposal which enables the beneficiaries to exercise whole rights vested in the subject year within two years. However, the beneficiary who retires during the subject year is the exception for this clause. We will carefully review its validity if the restricted period is regarded as too long.
We generally vote against the stock compensation granted to statutory auditors and the directors who become members of the audit committee under the audit committee system.
E-25

As directors who become members of the audit committee at the company with a three committee structure are required to perform duties as director, we consider the stock compensation for them differently from statutory auditors and the directors who become members of the audit committee under the audit committee system at the company with a statutory auditor structure.
We generally vote against the stock compensation granted to any third parties other than employees.
We generally vote against the stock compensation if it is judged likely to be used as a tool for takeover defense.

The granted amount is disclosed;
Outside directors, statutory auditors and the directors who become members of the audit committee under the audit committee system are not included in recipients;
There has been no serious scandal involving recipients during their tenure;
The subject company has not suffered from loss for the three consecutive year, or its business performance is not judged to significantly lag relative to peers in the same industry;
There has been no corporate scandal that has significant social effects on the subject company and has impaired, or likely to impair, the shareholder value during the tenure of recipients;
The subject company has not committed window-dressing and inadequate accounting activities during the tenure of recipients.
8. Cross-shareholdings
If the company holds shares for relationship purpose, we believe that the company is required to explain about medium- to long-term business and financial strategies and disclose criteria for proxy voting decisions and voting results, etc. If no reasonable views are indicated and no constructive dialogue is conducted, we consider to vote against the director candidates who are top executives. It is important that the company does not prevent companies who have its shares as a “policy-share-holding” from selling/reducing them.
9. Capital Policy
As the capital policy of listed companies is likely to have important impact on the shareholder value and the interest of shareholders of the subject company, the subject company should implement the reasonable capital policy and explain basic policies of the capital policy to shareholders. We consider voting against the proposals concerning the capital policy that is judged to impair the shareholder value. If there exists the capital policy that is not part of proposals at the shareholders meeting but is judged to impair the shareholder value, we consider voting against reelection of director candidates.

Preamble
SEBI vide its circular reference no. SEBI/IMD/Cir No.18/198647/2010 dated March 15, 2010 has stated that mutual fund should play an active role in ensuring better corporate governance of listed companies. The said circular stated that the AMCs should disclose their general policies and procedures for exercising the voting rights in respect of shares held by them.
Subsequently, SEBI vide its circular ref. no. CIR/IMD/DF/05/2014 dated March 24, 2014, SEBI/HO/IMD/DF2/CIR/P/2016/68 dated August 10, 2016 and SEBI vide its circular ref. no. CIR/CFD/CMD1/ 168 /2019 dated December 24, 2019 have amended certain provisions of above mentioned circular specifying additional compliance / disclosure requirements with respect to exercise of voting rights by mutual funds.
This policy is drafted in pursuance of SEBI circular dated March 15, 2010 read with March 24, 2014, August 10, 2016 and December 24, 2019 and provides general philosophy, broad guidelines, procedures and principles for exercising voting rights.
Invesco Asset Management (India) Private Limited (“IAMI”) is an Investment Manager to the scheme(s) of Invesco Mutual Fund (“the Fund”). As an investment manager, IAMI has fiduciary responsibility to act in the best interest of unit-holders of the Fund. This responsibility includes exercising voting rights attached to the securities of the companies in which the schemes of the Fund invest. It will be IAMI’s endeavor to participate in the voting process (i.e. exercise voting rights) based on the philosophy enunciated in this policy.
B.
Philosophy of Voting Policy
Good corporate governance ensures that a corporation is managed keeping in mind the long-term interest of shareholders. Promoting good corporate governance standards forms an integral part of corporate ownership responsibilities.
With this in the forefront, IAMI expects all corporations, in which it invests in, to comply with high corporate governance standards. Accordingly, as the decision to invest is generally an endorsement of sound management practices, IAMI may generally vote with the management of these corporations. However, when IAMI is of the view that the unit holders will be prejudiced by any such proposal, then it may vote against such proposal to protect the interest of unit holders. Also in case of resolutions moved by the shareholders of the company, IAMI will exercise its voting rights in the best interest of its unit holders. In certain circumstances, IAMI may also decide to refrain from voting where it has insufficient information or there is conflict of interest or it does not have a clear stance on the proposal under consideration.
IAMI, as an investment manager, will generally vote in accordance with the Voting Policy. However, it may deviate from the policy if there are particular facts and/or circumstances that warrant for such deviation to protect the interests of unit-holders of the Fund.
C.
Conflict of Interest in Exercising Voting Rights
IAMI, under schemes, may invest in the securities of associate/group companies (to the extent permitted under SEBI (Mutual Funds) Regulations, 1996 as amended from time to time). Further, IAMI is an Indian subsidiary of global organization consisting of many affiliates. Moreover, schemes under IAMI may invest in securities of companies which have invested in schemes of Invesco Mutual Fund. Such scenarios may lead to a situation creating conflict of interest. Potential Conflict of interest may also arise if IAMI and the investee company are associates or are part of the same group; or the investee company holds a material ownership interest in IAMI; a nominee of IAMI has been appointed as a director of the investee company or having cross-directorships, the Investee Company is an entity participating in the distribution of investment products advised or administered by the Investment Manager and/or any of its affiliate; the Investee Company is a client of Investment Manager and/or its affiliates.
IAMI will attempt to avoid conflict of interest and will exercise its voting rights in the best interest of the unit-holders. Voting decisions in such cases will be based on merits without any bias and the same parameters will be applied for taking voting decisions as are applied for other companies.
E-34

In cases where there is a potential conflict of interest, IAMI will vote exactly as per recommendations of the proxy voting advisory entity with no modifications whatsoever. In case there is need for a clearer direction, the matter may be referred to the Investment committee for its guidance. Rationale for decision taken/ voting on the issue shall be recorded.
D.
Voting Policy Guidelines
The matters regarding, but not limited to, which the IAMI may exercise the voting rights in the Annual General Meeting (AGMs) /Extra Ordinary General Meeting (EGMs)/ Through Postal Ballots/Electronic voting of the investee companies are as follows:
Corporate governance matters, including changes in the state of incorporation, merger and other corporate restructuring and anti- takeover provisions.
Changes to capital structure, including increase and decrease of capital and preferred stock issuances.
Stock option plans and other management compensation issues.
Social and corporate responsibility issues.
Appointment and Removal of Directors.
Any other issue that may affect the interest of the shareholders in general and interest of the unit-holders in particular.
IAMI will exercise voting rights keeping in mind the need to improve economic value of the companies and importance of protecting the interests of unit holders of its schemes but subject to importance of the matter and cost/time implications. The analysts in equity team will make recommendations on key voting issues and same will be approved by the Head of Equity or Fund Manager. In case of conflicts or need for a clearer direction, the matter may be referred to the Voting Committee for its guidance.
E.
Voting Committee
As a guiding principle, IAMI shall exercise voting rights solely in the interest of unit holders of the Fund. IAMI has constituted a Voting Committee (VC). The Committee is empowered to provide guidance on the voting matters referred to it, establish voting guidelines and procedures as it may consider necessary and is responsible to ensure that these guidelines and procedures are adhered to and also make changes in the Policy as may be required from time to time. The members of this Committee are as follows:
CEO / COO/Head - Operations (any one)
Head of Compliance or Member of compliance team
Head of Equity or Fund Manager (equity)
Head of Fixed Income and/ or Fund Managers (fixed income)
Any other representative as the Committee may co-opt from time to time
Broad Guidelines for functioning of Voting Committee are:
1. Voting Committee may record its decisions by circulation including decisions/guidance on voting matters that have been referred to it.
2. Voting Committee may consult with outside experts and other investors on issues as it may deem fit
3. Decisions of Voting Committee should be maintained by compliance
4. Details of voting decisions taken by the Fund Management team will be presented to the Voting Committee/Investment Committee.
E-35

5. Voting Committee may review this policy from time to time.
F.
Steps (Procedure) in Exercising Voting Rights
The following points outline the key steps in exercising Voting rights:
1) Notification of company AGMs / EGMs and relevant voting items to Fund Management Team.
2) The IAMI shall endeavor to vote for all holdings of the Fund, aggregated for all its schemes, but subject to the importance of the matter and the cost/time implications. The voting will cover all equity holding across all schemes of Invesco Mutual Fund. (except for companies which are held only in arbitrage fund)
3) Custodian will send ballots and or other relevant papers (notice of meeting, proxy form, attendance slips etc.) to IAMI relating to AGM/EGM as soon as it receives.
4) The fund management team is authorized to decide on voting decisions but may refer decisions to the Voting Committee for its guidance/direction.
5) Based on internal discussion within the fund management team, a decision would be arrived at as to whether IAMI should vote on the proposed resolution. Routine matters and ordinary resolutions like adoption of financials (unless there are significant auditor qualifications), dividend declaration, general updating/corrective amendments to the Articles of Association would also be considered for voting purpose. However IAMI may on a case to case basis, not vote on such resolutions, if it deems fit to do so.
6) Proposed resolutions would be discussed within the fund management team and decision would be taken on whether to vote (“for”/ “against”) or “abstain” from voting. IAMI may abstain from voting on proposals that do not have a readily determinable financial impact on shareholder value and/or matters for which disclosure is inadequate. For the remaining proposals, IAMI would vote either “for” or “against” based on overall merits and demerits of the proposed resolution. IAMI will generally support and vote “for” proposals which are likely to result in maximizing long-term investment returns for unit holders. IAMI would not support and will vote “against” proposals that appear to be detrimental to the company financials / interest of the minority shareholders or which would adversely impact shareholders’ value.
7) IAMI may exercise its voting rights by authorizing its own executives/authorized representative to attend the AGM/EGM or may instruct the Custodian to exercise voting rights in accordance with the instructions of IAMI.
8) IAMI may exercise its voting rights through Postal Ballot or may use Electronic voting mechanism, wherever available, either through its own executives or by authorizing the Custodian. The records of voting exercised through Postal Ballot will be maintained by IAMI.
9) IAMI may utilize the services of third party professional agencies for getting in-depth analyses of proposals and vote recommendations. However, the recommendations of the third party agencies will be non-binding in nature. IAMI will perform due diligence on proxy voting advisory firms at the time of initial selection as well as at the time of renewal of services of the proxy voting. The due diligence will be carried out on parameters viz. resource strength, Companies under coverage, extent of institutional ownership, depth of analysis, quality of advice / recommendations, analyst access & support, timely availability of reports, composition of board of directors, advisory board and top management, web-based interface platform and clientele.
10) The rationale supporting each voting decision (For, Against and Abstain) will be recorded and such records will be retained for number of years (currently 8 years) as may be required under the SEBI (Mutual Funds) Regulations, 1996 from time to time.
E-36

G.
Details of Service Provider

The scope of the agreement with IIAS includes: IIAS shall provide non-binding Voting Recommendations for each Voting Event for Investee companies, access to their research portal and analysts for any discussion, access to their online voting management systems etc. The details of the service provider (currently IIAS) are provided in the “Rationale for continuation of Proxy Voting advisory report” which is prepared once in 2 years. IIAS has standardized voting policies and has a committee-based voting decision making system. Their analysis to arrive at the recommendations are detailed in nature and recommendations are fairly objective. However, the recommendations of IIAS are non-binding in nature, and IAMI, reserves the right to vote differently based on their own judgement on the matter involved.
H.

Item 29. Persons Controlled by or Under Common Control with the Fund.
None.
Item 30. Indemnification.
Indemnification provisions for officers, trustees, and employees of the Registrant are set forth in Article VIII of the Registrant’s Second Amended and Restated Agreement and Declaration of Trust and Article VIII of its Amended and Restated Bylaws, and are hereby incorporated by reference. See Item 28(a) and (b) above. Under the Second Amended and Restated Agreement and Declaration of Trust, amended and restated effective as of April 11, 2017, as amended, (i) Trustees or officers, when acting in such capacity, shall not be personally liable for any act, omission or obligation of the Registrant or any Trustee or officer except by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office with the Trust; (ii) every Trustee, officer, employee or agent of the Registrant shall be indemnified to the fullest extent permitted under the Delaware Statutory Trust Act, the Registrant’s Amended and Restated Bylaws and other applicable law; (iii) in case any shareholder or former shareholder of the Registrant shall be held to be personally liable solely by reason of his being or having been a shareholder of the Registrant or any portfolio or class and not because of his acts or omissions or for some other reason, the shareholder or former shareholder (or his heirs, executors, administrators or other legal representatives, or, in the case of a corporation or other entity, its corporate or general successor) shall be entitled, out of the assets belonging to the applicable portfolio (or allocable to the applicable class), to be held harmless from and indemnified against all loss and expense arising from such liability in accordance with the Amended and Restated Bylaws and applicable law. The Registrant, on behalf of the affected portfolio (or class), shall upon request by the shareholder, assume the defense of any such claim made against the shareholder for any act or obligation of that portfolio (or class).
The Registrant and other investment companies and their respective officers and trustees are insured under a joint Mutual Fund Directors and Officers Liability Policy, issued by ICI Mutual Insurance Company and certain other domestic issuers, with limits up to $100,000,000 and an additional $50,000,000 of excess coverage (plus an additional $30,000,000 limit that applies to independent directors/trustees only).
Section 16 of the Master Investment Advisory Agreement between the Registrant and Invesco Advisers, Inc. (“Invesco Advisers”) provides that in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of obligations or duties hereunder on the part of Invesco Advisers or any of its officers, directors or employees, that Invesco Advisers shall not be subject to liability to the Registrant or to any series of the Registrant, or to any shareholder of any series of the Registrant for any act or omission in the course of, or connected with, rendering services hereunder or for any losses that may be sustained in the purchase, holding or sale of any security. Any liability of Invesco Advisers to any series of the Registrant shall not automatically impart liability on the part of Invesco Advisers to any other series of the Registrant. No series of the Registrant shall be liable for the obligations of any other series of the Registrant.
Section 10 of the Master Intergroup Sub-Advisory Contract for Mutual Funds (the Sub-Advisory Contract) between Invesco Advisers, on behalf of Registrant, and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc., Invesco Canada Ltd. Invesco PowerShares Capital Management LLC and Invesco Asset Management (India) Private Limited (each a Sub-Adviser, collectively the Sub-Advisers) provides that the Sub-Advisor shall not be liable for any costs or liabilities arising from any error of judgment or mistake of law or any loss suffered by any series of the Registrant or the Registrant in connection with the matters to which the Sub-Advisory Contract relates except a loss resulting from willful misfeasance, bad faith or gross negligence on the part of the Sub-Adviser in the performance by the Sub-adviser of its duties or from reckless disregard by the Sub-Adviser of its obligations and duties under the Sub-Advisory Contract.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the “Act”) may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the

Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in connection with the successful defense of any action suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the shares being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy, as expressed in the Act and will be governed by final adjudication of such issue.
Item 31. Business and Other Connections of the Investment Adviser.
The only employment of a substantial nature of Adviser’s directors and officers is with the Advisers and its affiliated companies. For information as to the business, profession, vocation or employment of a substantial nature of each of the officers and directors of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc., Invesco Canada Ltd., Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (each a Sub-Advisor, collectively the Sub-Advisors) reference is made to Form ADV filed under the Investment Advisers Act of 1940 by each Sub-Adviser herein incorporated by reference.

MEMORANDUM OF AGREEMENT

(Expense Limitations)

This Memorandum of Agreement is entered into as of the Effective Date on the attached exhibits (the “Exhibits”), between AIM Counselor Series Trust (Invesco Counselor Series Trust), AIM Equity Funds (Invesco Equity Funds), AIM Funds Group (Invesco Funds Group), AIM Growth Series (Invesco Growth Series), AIM International Mutual Funds (Invesco International Mutual Funds), AIM Investment Funds (Invesco Investment Funds), AIM Investment Securities Funds (Invesco Investment Securities Funds), AIM Sector Funds (Invesco Sector Funds), AIM Tax-Exempt Funds (Invesco Tax-Exempt Funds), AIM Variable Insurance Funds (Invesco Variable Insurance Funds), Invesco Management Trust and Short-Term Investments Trust (each a “Trust” or, collectively, the “Trusts”), on behalf of the funds listed on the Exhibits to this Memorandum of Agreement (the “Funds”), and Invesco Advisers, Inc. (“Invesco”). Invesco shall and hereby agrees to waive fees or reimburse expenses of each Fund, on behalf of its respective classes as applicable, severally and not jointly, as indicated in the attached Exhibits.

For and in consideration of the mutual terms and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Trusts and Invesco agree as follows:

For the contractual expense limitations identified on Exhibit A (“Expense Limitations”), Invesco agrees until at least the expiration date set forth on Exhibit A (each, an “Expiration Date”) that Invesco will waive its fees or reimburse expenses to the extent that expenses of a class of a Fund (excluding (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; and (v) expenses that each Fund has incurred but did not actually pay because of an expense offset arrangement, if applicable) exceed the Expense Limitation rate, on an average of the daily net assets allocable to such class on an annualized basis1. Neither a Trust nor Invesco may remove or amend the Expense Limitations to a Fund’s detriment prior to the Expiration Date without requesting and receiving the approval of the Board of Trustees of the applicable Fund’s Trust to remove or amend such Expense Limitations. Invesco will not have any right to reimbursement of any amount so waived or reimbursed.

For the Expense Limitations, Invesco agrees to review the then-current expense limitations for each class of each Fund listed on the Exhibits on a date prior to the Expiration Date to determine whether such limitations should be amended, continued or terminated. The expense limitations will expire upon the Expiration Date unless Invesco has agreed to continue them. The Exhibits will be amended to reflect any such agreement.

From time to time, Invesco may establish amend and/or terminate Voluntary expense limitations at any time in its sole discretion. These Voluntary Limits are set forth on Exhibit B. Any delay or failure by Invesco to update this Memorandum of Agreement with regards to the terminations, extensions, or expirations of the Voluntary Limits shall have no effect on the term of such Voluntary Limitations; the Voluntary Limitations are listed herein for informational purposes only.

It is expressly agreed that the obligations of each Trust hereunder shall not be binding upon any of the Trustees, shareholders, nominees, officers, agents or employees of the Trusts personally, but shall only bind the assets and property of each Fund, as provided in each Trust’s Agreement and Declaration of Trust. The execution and delivery of this Memorandum of Agreement have been authorized by the Trustees of the Trusts, and this Memorandum of Agreement has been executed and delivered by an authorized officer of the Trusts acting as such; neither such authorization by such Trustees nor such execution and delivery by such officer shall be deemed to have been made by any of them individually or to impose any liability on any of them personally, but shall bind only the assets and property of the Funds, as provided in each Trust’s Agreement and Declaration of Trust.

Acquired fund fees and expenses are not fees or expenses incurred by a Fund directly but are expenses of the investment companies in which a Fund invests. These fees and expenses are incurred indirectly through the valuation of a Fund’s investment in these investment companies. Acquired fund fees and expenses are required to be disclosed and included in the total annual Fund operating expenses in the prospectus fee table. As a result, the net total annual Fund operating expenses shown in the prospectus fee table may exceed the expense limits reflected in Exhibit A.


IN WITNESS WHEREOF, each of the Trusts, on behalf of itself and its Funds listed on the Exhibits to this Memorandum of Agreement, and Invesco have entered into this Memorandum of Agreement as of the Effective Dates on the attached Exhibits.
