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. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

 

	1 Year	3 Years	5 Years	10 Years
Class A	$435	$669	$922	$1,644
Class C	$290	$588	$1,011	$1,995
Class R	$139	$434	$750	$1,646
Class Y	$89	$278	$482	$1,073
Class R5	$84	$262	$455	$1,014
Class R6	$80	$249	$433	$966

You would pay the following expenses if you did not redeem your shares:

 

	1 Year	3 Years	5 Years	10 Years
Class A	$435	$669	$922	$1,644
Class C	$190	$588	$1,011	$1,995
Class R	$139	$434	$750	$1,646
Class Y	$89	$278	$482	$1,073
Class R5	$84	$262	$455	$1,014
Class R6	$80	$249	$433	$966

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 49% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests mainly in floating rate loans (sometimes referred to as "adjustable rate loans") that hold (or in the judgment of the investment adviser, hold) a senior position in the capital structure of U.S. and foreign corporations, partnerships or other business entities that, under normal

circumstances, allow them to have priority of claim ahead of (or at least as high as) other obligations of a borrower in the event of liquidation. These investments are referred to as "Senior Loans." Senior Loans may be collateralized or uncollateralized. They typically pay interest at rates that float above, or are adjusted periodically based on, a benchmark that reflects current interest rates.

Under normal market conditions, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in Senior Loans, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund may invest in Senior Loans directly as an original lender, or by assignment from a lender, or it may invest indirectly through loan participation agreements. While most of these Senior Loans will be collateralized, the Fund can also invest up to 10% of its net assets (plus the amount of borrowings for investment purposes) in uncollateralized Senior Loans.

The Fund can invest up to 20% of its total assets in cash (whether U.S. dollars or a foreign currency) or cash equivalents, or in other loans, securities and other investments, including but not limited to: secured or unsecured fixed-rate loans, fixed or floating rate notes or bonds, securities issued or guaranteed by the U.S. government or its agencies or instrumentalities, investment-grade short-term debt obligations, equity securities (including common stocks, preferred stocks, rights, warrants, and securities convertible into common stock) and derivatives. The Fund also may invest in Senior Loans made in connection with highly leveraged transactions, including but not limited to, operating loans, leveraged buyout loans, and leveraged capitalization loans. The Fund will invest 25% or more of its total assets in instruments of the group of industries in the financial securities sector.

The Fund can invest in investment-grade or below-investment-grade debt instruments (sometimes referred to as "high yield" or "junk" securities). The Fund can invest up to 100% of its assets in debt instruments rated below-investment-grade, and will normally invest a substantial portion of its assets in those securities. "Investment-grade" debt instruments are rated in one of the four highest rating categories by nationally recognized statistical rating organizations such as Moody's or S&P Global Ratings (or, in the case of unrated securities, determined by the Adviser to be comparable to securities rated investment-grade). The Fund may also invest in unrated instruments, in which case the Fund's Adviser may assign ratings to those instruments, after assessing their credit quality and other factors, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. The Fund may invest in defaulted or distressed loans and loans to bankrupt companies.

The Fund may invest in securities of U.S. and foreign issuers. The Fund can invest in Senior Loans or other investments (such as subordinated debt and fixed-rate loans) issued by foreign entities.

The Fund has no requirements as to the range of maturities of the debt instruments it can buy or as to the market capitalization of the issuers of those instruments. The Fund can borrow up to one-third of the Fund's assets (including the amount borrowed) and use other techniques to manage its cash flow, to redeem shares, or to purchase assets, a technique referred to as "leverage." The Fund may also use certain types of derivative investments to try to enhance income or to seek to manage (hedge) investment risks, including, but not limited to, options, futures contracts, swaps, and "structured" notes.

The Fund can engage in foreign currency transactions either on a spot basis (i.e. for prompt delivery and settlement at the rate prevailing in the currency exchange market at the time) or through forward foreign currency contracts to seek to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. The Fund can use currency futures and currency swaps to seek to hedge its exposure to foreign currencies.

The Fund may invest without limitation in obligations for which there is no readily available trading market or which are otherwise illiquid, including securities restricted as to resale such as those contained in Rule 144A

promulgated under the Securities Act of 1933, as amended, and other types of exempt securities.

In selecting investments for the Fund, the portfolio managers evaluate overall investment opportunities and risks among the types of investments the Fund can hold. They analyze the credit standing and risks of borrowers whose loans or debt securities they are considering for the Fund's portfolio. They evaluate information about borrowers from their own research or research supplied by rating organizations, agent banks or other sources and select only those loans that they believe are likely to pay the interest and repay the principal when it becomes due. The portfolio managers consider many factors, including, among others,

There can be no assurance that the portfolio managers' analysis will identify all of the factors that may impair the value of a Senior Loan or other investment.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

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. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.

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.

Senior Loans and Other Loans Risk. Risks associated with an investment in Senior Loans include credit risk, interest rate risk, liquidity risk, valuation risk and prepayment risk. These risks are typically associated with debt securities but may be heightened in part because of the limited public information regarding Senior Loans. Senior Loans generally are floating rate loans, which are subject to interest rate risk as the interest paid on the floating rate loans adjusts periodically based on changes in widely accepted reference rates. Lack of an active trading market, restrictions on resale, irregular trading activity, wide bid/ask spreads and extended trade settlement periods may impair the Fund's ability to sell Senior Loans within its desired time frame or at an acceptable price and its ability to accurately value existing and prospective investments. Extended trade settlement periods may result in cash not being immediately available to the Fund. As a result, the Fund may have to sell other investments or engage in borrowing transactions to raise cash to meet its obligations. The risk of holding Senior Loans is also directly tied to the risk of insolvency or bankruptcy of the issuing banks. The value of Senior Loans can be affected by and sensitive to changes in government regulation and to economic downturns in the United States and abroad. Senior loans are also subject to the risk that a court could subordinate a senior loan or take other action detrimental to the holders of senior loans. Loans are subject to the risk that the value of the collateral, if any, securing a loan may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate or take possession of. Loan investments are often issued in connection with highly leveraged transactions which are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy. Highly leveraged loans also may be less liquid than other loans. These risks could cause the Fund to lose income or principal on a particular investment, which in turn could affect the Fund's returns. Newly originated loans (including reissuances and restructured loans) may possess lower levels of credit document protections than has historically been the case. Accordingly, in the event of default the Fund may experience lower levels of recoveries than has historically been the norm.

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 credit analysis applied to the Fund's debt securities 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.

High Yield Debt Securities (Junk Bond) Risk. Compared to higher quality debt securities, high yield debt securities (commonly referred to as "junk bonds") and other lower-rated securities involve a greater risk of default or price changes due to changes in the credit quality of the issuer because they are generally unsecured and may be subordinated to other creditors' claims. High yield debt securities often are issued by smaller, less creditworthy companies or by highly leveraged (for example, indebted) firms. High yield debt securities are considered speculative with respect to the issuer's capacity to pay interest and repay principal, are more susceptible to default or decline in market value and are less liquid than investment grade debt securities. Prices of high yield debt securities tend to be very volatile. The values of high yield debt securities often fluctuate more in response to company, political, regulatory or economic developments than higher quality

bonds, and their values can decline significantly over short periods of time or during periods of economic difficulty when the bonds could be difficult to value or sell at a fair price, thus subjecting the Fund to a substantial risk of loss.

Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed income investments, particularly those with longer maturities. Such changes and resulting increased volatility may adversely impact the Fund, including its operations, universe of potential investment options, and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets, which could result in higher than normal redemptions by shareholders, which could potentially increase the Fund's portfolio turnover rate and transaction costs.

Defaulted Securities Risk. As compared with non-defaulted securities, defaulted securities pose a greater risk that principal will not be repaid. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

This risk also applies to investments in loans to bankrupt companies.

Concentration in Financial Securities Sector Risk. The Fund will not concentrate its investments in issuers in any one industry, except that the Fund may invest without limit in instruments of the group of industries in the financial securities sector. Financial securities industries may be more susceptible to particular economic and regulatory events such as volatility in the financial markets and interest rates, changes in domestic and foreign monetary policy, and changes in industry regulations.

Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of possible seizure, expropriation, nationalization, political or social instability, changes in economic or taxation policies or other adverse political or economic developments (in which the Fund could lose its entire investments in a certain market) and the difficulty of enforcing obligations in other countries, including the possible adoption of foreign governmental restrictions such as exchange controls. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs. To the extent the Fund invests in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund's returns, unless the Fund has hedged its foreign currency exposure. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, may not always be successful. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. From time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the

United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company's performance. Additionally, one or more of these companies could suffer damage to its reputation if the market identifies it as a company that invests or deals with countries that the U.S. government identifies as state sponsors of terrorism or is subject to sanctions.

Investing in Stocks Risk. The value of the Fund's portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall or rise sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. However, individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. A variety of factors can negatively affect the price of a particular company's stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company's sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), Fund share values may fluctuate more in response to events affecting the market for those types of securities.

Preferred Securities Risk. There are special risks associated with investing in preferred securities compared to those applicable generally to equity securities. Preferred securities may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer. Preferred securities also may be subordinated to bonds or other debt instruments in an issuer's capital structure, subjecting them to a greater risk of non-payment than more senior securities. Preferred securities may include provisions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received any income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.

Rights and Warrants Risk. Warrants may be significantly less valuable or worthless on their expiration date and may also be postponed or terminated early, resulting in a partial or total loss. Rights are similar to warrants, but normally have a short duration and are distributed directly by the issuer to its shareholders. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer. Warrants and rights are highly volatile and, therefore, more susceptible to sharp declines in value than the underlying security might be. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price.

Convertible Securities Risk. The market values of convertible securities are affected by market interest rates, the risk of actual issuer default on interest or principal payments and the value of the underlying common stock into which the convertible security may be converted. Additionally, a convertible security is subject to the same types of market and issuer risks that apply to the underlying common stock. In addition, certain convertible securities are subject to involuntary conversions and may undergo principal write-downs upon the occurrence of certain triggering events, and, as a result, are subject to an increased risk of loss. Convertible securities may be rated below investment grade and therefore considered to have more speculative characteristics and greater susceptibility to default or decline in market value than investment grade securities.

Warrants, Equity Securities and Junior Debt Securities of the Borrower Risk. Warrants, equity securities and junior debt securities have

a subordinate claim on a Borrower's assets as compared with Senior Loans. As a result, the values of warrants, equity securities and junior debt securities generally are more dependent on the financial condition of the Borrower and less dependent on fluctuations in interest rates than are the values of many debt securities. The values of warrants, equity securities and junior debt securities may be more volatile than those of Senior Loans and thus may increase the volatility of the Fund's net asset value. Additionally, warrants may be significantly less valuable on their relevant expiration date resulting in a loss of money or they may expire worthless resulting in a total loss of the investment. Warrants may also be postponed or terminated early resulting in a partial or total loss of the investment. Warrants may also be illiquid.

U.S. Government Obligations Risk. U.S. government securities include securities that are issued or guaranteed by the U.S. Treasury, by various agencies of the U.S. government, or by various instrumentalities which have been established or sponsored by the U.S. government. U.S. Treasury securities are backed by the "full faith and credit" of the United States, which may be negatively affected by an actual or threatened failure of the U.S. government to pay its obligations. Securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may or may not be backed by the full faith and credit of the United States. In the case of those U.S. government securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate.

Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund's returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund's ability to use certain derivatives or their cost. Derivatives strategies may not always be successful. For example, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions.

Liquidity Risk. The Fund may be unable to sell illiquid investments at the time or price it desires and, as a result, could lose its entire investment in such investments. Liquid securities can become illiquid during periods of market stress. If a significant amount of the Fund's securities become illiquid, the Fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Borrowing Risk. Borrowing money to buy securities exposes the Fund to leverage and will cause the Fund's share price to be more volatile because leverage will exaggerate the effect of any increase or decrease in the value of the Fund's portfolio securities. Borrowing money may also

require the Fund to liquidate positions when it may not be advantageous to do so. In addition, the Fund will incur interest expenses and other fees on borrowed money. There can be no assurance that the Fund's borrowing strategy will enhance and not reduce the Fund's returns.

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.

Rule 144A Securities and Other Exempt Securities Risk. The market for Rule 144A and other securities exempt from certain registration requirements may be less active than the market for publicly-traded securities. Rule 144A and other exempt securities, while initially privately placed, carry the risk that their liquidity may become impaired and the Fund may be unable to dispose of the securities at a desirable time or price.

Environmental, Social and Governance (ESG) Considerations Risk. The ESG considerations that may be assessed as part of a credit research process to implement the Fund's investment strategy in pursuit of its investment objective may vary across types of eligible investments and issuers, and not every ESG factor may be identified or evaluated for every investment, and not every investment or issuer may be evaluated for ESG considerations. The incorporation of ESG factors as part of a credit analysis may affect the Fund's exposure to certain issuers or industries and may not work as intended. 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.

Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund's valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund's net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

Management Risk. The Fund is actively managed and depends heavily on the Adviser's or Sub-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 or Sub-Adviser's investment techniques or investment decisions will produce the desired results. 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.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Senior Floating Rate Fund (the predecessor fund) as the result of a reorganization consummated after the close of business on May 24,

2019 (the "Reorganization"). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund's and the Fund's performance to that of a broad measure of market performance and an additional index with characteristics relevant to the Fund. The Fund's (and the predecessor fund's) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund. Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund were reorganized into Class A, Class C, Class R, Class Y and Class R6 shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R, Class Y and Class R6 shares' returns of the Fund will be different from the returns of the predecessor fund as they have different expenses.

Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.

All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund's expenses.

Updated performance information is available on the Fund's website at www.invesco.com/us.

Class R5 shares of the Fund are offered only to grandfathered investors. With respect to Class R5 and Class R6 shares, there is no minimum initial investment for Employer Sponsored Retirement and Benefit Plans investing through a retirement platform that administers at least $2.5 billion in retirement plan assets. All other Employer Sponsored Retirement and Benefit Plans must meet a minimum initial investment of at least $1 million in each Fund in which it invests.

For all other institutional investors purchasing Class R5 or Class R6 shares, the minimum initial investment in each share class is $1 million, unless such investment is made by (i) an investment company, as defined under the Investment Company Act of 1940, as amended (1940 Act), that is part of a family of investment companies which own in the aggregate at least $100 million in securities, or (ii) an account established with a 529 college savings plan managed by Invesco, in which case there is no minimum initial investment.

There are no minimum investment amounts for Class R6 shares held through retail omnibus accounts maintained by an intermediary, such as a broker, that (i) generally charges an asset-based fee or commission in addition to those described in this prospectus, and (ii) maintains Class R6 shares and makes them available to retail investors.

Tax Information

The Fund's distributions primarily are taxable to you as ordinary income, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan, 529 college savings plan or individual retirement account. Any distributions from a 401(k) plan or individual retirement account may be taxed as ordinary income when withdrawn from such plan or account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund, the Fund's distributor or its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary's website for more information.
