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 may invest up to 20% of its net assets in money market instruments that may be subject to federal taxes, including Treasury securities, repurchase agreements, commercial
paper, and U.S. dollar-denominated foreign securities.
The Fund invests only 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, 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 will limit investments
to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase.
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 portfolio 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.
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.
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 credit research process utilized by the Fund to implement its investment strategy in
pursuit of its investment objective considers factors that include, but are not limited to, an issuer’s operations, capital structure and environmental, social and governance (“ESG”) considerations. Credit quality analysis
therefore may consider whether any ESG factors pose a material financial risk or opportunity to an issuer.
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
You could lose money by investing in the Fund. An investment in the Fund 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.
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 which 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.
