Example:

The following example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds.

The example assumes that you invest $1,000 in the Fund for the time periods indicated and the Fund repurchases all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year, that the Fund's operating expenses remain the same each year and that all dividends and other distributions are reinvested at net asset value. This example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	One Year	Three Years	Five Years	Ten Years
Class A Shares	$52	$92	$135	$255

	One Year	Three Years	Five Years	Ten Years
Class C Shares	$38	$84	$144	$305
Class Y Shares	$17	$54	$93	$203
Class IB Shares	$17	$54	$93	$203
Class IC Shares	$19	$59	$101	$219

You would pay the following expenses if you did not tender your Shares for repurchase by the Fund:

	One Year	Three Years	Five Years	Ten Years
Class A Shares	$52	$92	$135	$255
Class C Shares	$28	$84	$144	$305
Class Y Shares	$17	$54	$93	$203
Class IB Shares	$17	$54	$93	$203
Class IC Shares	$19	$59	$101	$219

The purpose of the table above is to assist you in understanding the various costs and expenses that an investor in the Fund will bear directly or indirectly.

This example should not be considered a representation of future expenses, and the Fund's actual expenses may be more or less than those shown.

Prospectus Summary

This summary is qualified by reference to the more detailed information included elsewhere in this Prospectus and in the Statement of Additional Information.

The Fund

The Fund is a diversified, closed-end management investment company. The Fund completed an initial public offering in October 1989. The Fund was organized as a Massachusetts business trust on July 14, 1989, and was redomesticated as a Delaware statutory trust on October 15, 2012. The Fund has continuously offered its Shares since November 1989. The Fund's investment adviser is Invesco Advisers, Inc. (the "Adviser"). The Fund's investment sub-adviser is Invesco Senior Secured Asset Management, Inc.

The Offering

As of the date of this Prospectus, the Fund continuously offers three classes of Shares - Class A Shares, Class C Shares, and Class Y Shares, which are available to certain investors as described under "Purchase of Shares - General" - through Invesco Distributors and through selected broker- dealers and financial services firms. Class IB Shares and Class IC Shares are not continuously offered. The only new Class IB Shares and Class IC Shares to be issued are those Class IB Shares and Class IC Shares issued to satisfy dividend and capital gain reinvestments. Shares are sold at their offering price, which is net asset value per Share for such class of Shares plus sales charges where applicable (see "Purchases of Shares - Class A Shares").

Invesco Distributors pays the broker-dealers and financial services firms participating in the continuous offering.

Investment Objective

The Fund's investment objective is to provide a high level of current income, consistent with preservation of capital. Although the Fund seeks capital preservation, it is not a money market fund or a certificate of deposit, and it differs substantially from these products with respect to risks and liquidity,

among other factors. There is no assurance that the Fund will achieve its investment objective. You should carefully consider the risks of investing in the Fund.

See "Principal Risks of Investing in the Fund."

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 adjustable rate senior loans ("Senior Loans"). Senior Loans are loans made to borrowers that may be corporations, partnerships or other entities ("Borrowers"). These Borrowers operate in a variety of industries and geographic regions, although most Senior Loans are made to Borrowers that are organized or located in the U.S. Interest rates on Senior Loans may adjust over different time periods. Prime based and federal funds rate loans reset periodically when the underlying rate resets. London Inter-Bank Offered Rate ("LIBOR") loans reset on set dates, typically every 30 to 90 days, but not to exceed one year.

Senior Loans generally are negotiated between a Borrower and several financial institution lenders ("Lenders") represented by one or more Lenders acting as agent of all the Lenders ("Agent"). The Agent is responsible for negotiating the loan agreement (the "Loan Agreement") that establishes the terms and conditions of the Senior Loan and the rights of the Borrower and the Lenders. The Fund may act as one of the group of original Lenders originating a Senior Loan, may purchase assignments of portions of Senior Loans from third parties and may invest in participations in Senior Loans. Senior Loans may include certain senior debt that is in the form of notes and not Loan Agreements. Senior Loans usually have the most senior position in a Borrower's capital structure or share the senior position with other senior debt securities of the Borrower. This capital structure position generally gives holders of Senior Loans a priority claim on some or all of the Borrower's assets in the event of default. Most of the Fund's Senior Loan investments will be secured by specific assets of the Borrower. Senior Loans also have contractual terms designed to protect Lenders. Certain of the loans in which the Fund may invest may be issued or offered as "covenant lite" loans, which have few or no financial maintenance covenants that would require a borrower to maintain certain financial metrics. The Fund generally acquires Senior Loans of Borrowers that, among other things, in the Adviser's judgment, can make timely payments on their Senior Loans and that satisfy other credit standards established by the Adviser. The Fund may, however, invest all or a substantial portion of its assets in below investment grade Senior Loans, which are considered speculative by rating agencies (and are often referred to as high-yielding, high risk investments or as "junk" investments). Because of their protective features, the Adviser believes that Senior Loans of Borrowers that are experiencing, or are more likely to experience, financial difficulty may represent attractive investment opportunities. Decisions to purchase or sell loans and securities are determined by the relative value considerations of the portfolio managers that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. 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; however, analysis of ESG factors may not be conducted on each issuer or Fund investment and is not determinative to an investment decision. The purchase or sale of loans and securities may be related to a decision to alter the Fund's macro risk exposure, a need to limit or reduce the Fund's exposure to a particular security or issuer, degradation of an issuer's credit quality, or general liquidity needs of the Fund.

Other investment policies. Other investment policies of the Fund include the following: the Fund may invest up to 20% of its total assets, measured at the time of investment, in Senior Loans made to Borrowers

that are organized or located in countries other than the U.S., including emerging markets, and, during normal market conditions, the Fund may invest up to 20% of its total assets in any combination of (1) warrants and equity securities (including common stocks, preferred stocks, rights and securities convertible into common stock), (2) high quality short-term debt securities, (3) other debt securities, including high-yield bonds and junior debt securities, (4) credit-linked deposits and (5) Treasury Inflation Protected Securities ("U.S. TIPS") and other inflation-indexed bonds issued by the U.S. government, its agencies or instrumentalities.

Investment grade securities are: (i) securities rated BBB- or higher by S&P Global Ratings (S&P) or Baa3 or higher by Moody's Investors Service, Inc. (Moody's) or an equivalent rating by another nationally recognized statistical rating organization (NRSRO), (ii) securities with comparable short- term NRSRO ratings, or (iii) unrated securities determined by the Adviser to be of comparable quality, each at the time of purchase.

The Fund may utilize financial leverage (i) to provide the Fund with additional liquidity to meet its obligations to repurchase its Shares pursuant to its repurchase offers and (ii) for investment purposes (i.e., to use such financial leverage to purchase additional portfolio securities consistent with the Fund's investment objective and primary investment strategy) to benefit the Fund's Common Shares. Generally speaking, if the Fund can invest the proceeds from financial leverage (i.e., money from borrowings or issuing preferred shares) in portfolio securities that have higher rates of return than the costs of such financial leverage and other expenses of the Fund, then the holders of Common Shares would have a net benefit. The Fund's policy on financial leverage allows the Fund to use financial leverage in the form of borrowings and/or preferred shares to the maximum extent allowable under the Investment Company Act of 1940, as amended (the "1940 Act").

The Fund may also invest in collateralized loan obligations and collateralized debt obligations, which are debt instruments backed solely by a pool of bonds, loans and/or other debt securities.

The Fund can invest in derivative instruments including futures contracts, swap contracts and forward foreign currency contracts.

The Fund can use currency futures to hedge its exposure to foreign currencies.

The Fund can use swap contracts, including interest rate swaps, to hedge or adjust its exposure to interest rates, and currency swaps, to hedge its exposure to foreign currencies. The Fund can also use swap contracts, including credit default swaps, to enhance the yield on its portfolio or to increase income available for distributions or for other non-hedging purposes.

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 mitigate the risk of foreign currency exposure.

The Fund can invest in structured notes and credit- linked notes. The Fund can use structured notes and credit linked notes to enhance the yield on its portfolio or to increase income available for distributions or for other non-hedging purposes.

Certain investment practices. The Fund may use various investment practices that involve special risks, including engaging in derivative transactions. See "Principal Investment Strategies of the Fund."

Anti-takeover provisions. The Fund's Declaration of Trust includes provisions that could limit the ability of other persons to acquire control of the Fund or to change the composition of its Board of Trustees. See "Description of Shares - Anti- Takeover Provisions in the Declaration of Trust."

Principal Risks

As with any 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, 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, military conflict, 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.

Senior Loans and Other Loans Risk. Risks associated with an investment in Senior Loans include credit risk, interest rate risk, liquidity risk and prepayment risk. These risks are typically associated with debt securities. 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. 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 that 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.

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.

Covenant Lite Loans Risk. Because covenant lite loans contain few or no financial maintenance covenants, covenant lite loans may not include terms that permit the lender of the loan to monitor the borrower's financial performance and, if certain criteria are breached, declare a default, which would allow the lender to restructure the loan or take other action intended to help mitigate losses. As a result, the Fund may experience relatively greater difficulty or delays in enforcing its rights on its holdings of covenant lite loans than its holdings of loans or securities with financial maintenance

covenants, which may result in losses to the Fund, especially during a downturn in the credit cycle.

LIBOR Transition Risk. The Fund may have investments in financial instruments that utilize the London Interbank Offered Rate ("LIBOR") as the reference or benchmark rate for variable interest rate calculations. LIBOR is intended to measure the rate generally at which banks can lend and borrow from one another in the relevant currency on an unsecured basis. Regulators and financial industry working groups in several jurisdictions have worked over the past several years to identify alternative reference rates ("ARRs") to replace LIBOR and to assist with the transition to the new ARRs. In connection with the transition, on March 5, 2021 the UK Financial Conduct Authority (FCA), the regulator that oversees LIBOR, announced that the majority of LIBOR rates would cease to be published or would no longer be representative on January 1, 2022. Consequently, the publication of most LIBOR rates ceased at the end of 2021, but a selection of widely used USD LIBOR rates continues to be published until June 2023 to allow for an orderly transition away from these rates. Additionally, key regulators have instructed banking institutions to cease entering into new contracts that reference these USD LIBOR settings after December 31, 2021, subject to certain limited exceptions.

There remains uncertainty and risks relating to the continuing LIBOR transition and its effects on the Fund and the instruments in which the Fund invests. For example, there can be no assurance that the composition or characteristics of any ARRs or financial instruments in which the Fund invests that utilize ARRs will be similar to or produce the same value or economic equivalence as LIBOR or that these instruments will have the same volume or liquidity. Additionally, although regulators have generally prohibited banking institutions from entering into new contracts that reference those USD LIBOR settings that continue to exist, there remains uncertainty and risks relating to certain "legacy" USD LIBOR instruments that were issued or entered into before December 31, 2021 and the process by which a replacement interest rate will be identified and implemented into these instruments when USD LIBOR is ultimately discontinued. The effects of such uncertainty and risks in "legacy" USD LIBOR instruments held by the Fund could result in losses to the Fund.

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.

High Yield Debt Securities (Junk Bond) Risk. Investments in high yield debt securities ("junk bonds") and other lower-rated securities will subject the Fund to substantial risk of loss. These securities are considered to be speculative with respect to the issuer's ability to pay interest and principal when due, 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.

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

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.

Changing Fixed Income Market Conditions Risk. The current low interest rate environment was created in part by the Federal Reserve Board (FRB) and certain foreign central banks keeping the federal funds and equivalent foreign rates near historical lows. Increases in the federal funds and equivalent foreign rates may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. 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 could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover and the Fund's transaction costs.

Financial Services Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and are disproportionately affected by unstable interest rates, volatility in the financial markets, changes in domestic and foreign monetary policy, and changes in industry regulations, each of which could adversely affect the profitability of such companies. Financial services companies may also have concentrated portfolios, which makes them especially vulnerable to unstable economic conditions.

Asset-Backed Securities Risk. Asset-backed securities, including collateralized debt obligations, are subject to prepayment or call risk, which is the risk that a borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans, which could result in the Fund reinvesting these early payments at lower interest rates, thereby reducing the Fund's income. Asset-backed securities also are subject to extension risk, which is the risk that a rise in interest rates could reduce the rate of prepayments, causing the price of the asset-backed securities and the Fund's share price to fall. Privately-issued asset- backed securities may be less liquid than other types of securities and the Fund may be unable to sell these securities at the time or price it desires. During periods of market stress, the Fund may be forced to sell these securities at significantly reduced prices, resulting in losses. Liquid privately- issued asset-backed securities can become illiquid during periods of market stress.

Collateralized Loan Obligations Risk. CLOs are subject to the risks of substantial losses due to actual defaults by underlying borrowers, which will be greater during periods of economic or financial stress. CLOs may also lose value due to collateral defaults and disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to CLO securities as a class. The risks of CLOs will be greater if the Fund invests in CLOs that hold loans of uncreditworthy borrowers or if the Fund holds subordinate tranches of the CLO that absorb losses from the defaults before senior tranches. In addition, CLOs are subject to interest rate risk and credit risk.

Credit Linked Notes Risk. Risks of credit linked notes include those risks associated with the underlying reference obligation including but not limited to market risk, interest rate risk, credit risk, default risk and, in some cases, foreign currency risk. An investor in a credit linked note bears counterparty risk or the risk that the issuer of the credit linked note will default or become bankrupt and not make timely payment of principal and interest of the structured security. Credit linked notes may be less liquid than other investments and therefore harder to dispose of at the desired time and price. In addition, credit linked notes may be leveraged and, as a result, small changes in the value of the underlying reference obligation may produce disproportionate losses to the Fund.

Foreign Securities Risk. 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. 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. Unless the Fund has hedged its foreign currency exposure, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful.

Emerging Market Securities Risk. Emerging markets (also referred to as developing markets) are generally subject to greater market volatility, political, social and economic instability, uncertain trading markets and more governmental limitations on foreign investment than more developed markets. In addition, companies operating in emerging markets may be subject to lower trading volume and greater price fluctuations than companies in more developed markets. Such countries' economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund's ability to evaluate such companies. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions (including bankruptcy, confiscatory taxation, expropriation, nationalization of a company's assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures and practices such as share blocking), or to obtain information needed to pursue or enforce such actions, may be limited. In addition, the ability of foreign entities to participate in privatization programs of certain developing or emerging market countries may be limited by local law. Investments in emerging market securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

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. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities also may be subordinated to bonds or other debt instruments, subjecting them to a greater risk of non-payment, may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer.

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 as 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.

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.

Inflation-Indexed Securities Risk. The values of inflation-indexed securities generally fluctuate in response to changes in real interest rates. Because of the inflation-adjustment feature, these securities typically have lower yields than traditional fixed-rate securities with similar maturities. Normally inflation-indexed securities will decline in price when real interest rates rise which could cause losses for the Fund. As a result, the Fund's income from its investments in these securities is likely to fluctuate considerably more than the income distributions of its investments in more traditional fixed-income 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.

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.

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.

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.

No Trading Market for Shares. The Fund is a closed-end investment company designed primarily for long-term investors and not as a trading vehicle. While there is no restriction on transferring the Shares, the Fund does not intend to list the Shares for trading on any national securities exchange. There is no secondary trading market for Shares. An investment in the Shares is illiquid. There is no guarantee that you will be able to sell all of the Shares that you desire to sell in any repurchase offer by the Fund.

Repurchase Offers

The Fund has a fundamental policy whereby it commits to make offers to repurchase Shares of the Fund. In order to provide liquidity to shareholders,

the Fund will make monthly offers to repurchase between 5% and 25% of its outstanding Shares at net asset value, subject to certain conditions. The repurchase request deadline will be the third Friday of each calendar month (or the preceding business day if such third Friday is not a business day). The repurchase price will be the Fund's net asset value as determined after the close of business on the repurchase pricing date. Under normal circumstances, the Fund expects that the repurchase pricing date will be the repurchase request deadline. The Fund generally will pay repurchase proceeds by the third business day after the repurchase pricing date, although payment for Shares may be as many as seven days after the repurchase request deadline; in any event, the Fund will pay such proceeds at least five business days before notification of the next repurchase offer.

The Fund will impose an early withdrawal charge payable to Invesco Distributors on most Class C Shares accepted for repurchase that have been held for less than one year of up to 1%. There is generally no early withdrawal charge on Class A Shares, although the Fund in certain circumstances may impose an early withdrawal charge on Class A Shares accepted for repurchase by the Fund which have been held for less than eighteen months. See "Purchase of Shares - Class A Shares." There are no early withdrawal charges on Class Y Shares, Class IB Shares or Class IC Shares. The Fund may borrow to, among other things, finance repurchases of Shares. Borrowings entail additional risks.

Repurchase Offer Risks. If the Fund repurchases more Shares than it is able to sell, the Fund's net assets may decline and its expense ratios may increase, and the Fund's ability to achieve its investment objective may be adversely affected. Moreover, this may force the Fund to sell assets it would not otherwise sell, and the Fund may be forced to dispose of Fund assets that may have declined in value. The Fund may borrow money to, among other things, finance repurchases of Shares. The rights of any lenders to the Fund to receive payments of interest on and repayments of principal of any borrowings will be senior to the rights of shareholders. The loan agreement for any borrowing likely will limit certain activities of the Fund, including the payment of dividends to holders of Shares in certain circumstances. Interest payments and fees incurred in connection with borrowings to finance repurchases of Shares will reduce the amount of net income available for payment to shareholders and may increase volatility of the net asset value of the Common Shares. See also the section above on "Financial Leverage Risk" and the section of the Prospectus entitled "Repurchase of Shares."

Distribution Plan and Service Plan

The Fund has adopted a distribution plan (the "Distribution Plan") with respect to each of its Class A Shares and Class C Shares and in so doing has agreed to comply with Rule 12b-1 under the 1940 Act, as if the Fund were an open-end investment company. The Fund also has adopted a service plan (the "Service Plan") with respect to each of its Class A Shares, Class C Shares and

Class IC Shares. There is no Distribution Plan or Service Plan for Class Y Shares or Class IB Shares and no Distribution Plan for Class IC Shares.

Under the Distribution Plan, the Fund pays distribution fees in connection with the sale and distribution of Class A Shares and Class C Shares. Under the Service Plan, the Fund pays service fees in connection with the provision of ongoing services to shareholders of Class A Shares,

Class C Shares and Class IC Shares and the maintenance of such shareholders' accounts. See "Purchase of Shares - Distribution Plan and Service Plan."

Distributions

The Fund plans to declare daily and pay monthly distributions of substantially all net investment income. Distributions cannot be assured, and the amount of each distribution is likely to vary. Net.capital gain, if any, will be distributed at least annually. A convenient way for investors to accumulate additional Shares is by reinvesting dividends and distributions in Shares of the Fund. Such Shares are acquired at net asset value per Share (without a sales charge) on the applicable payable date of the dividend or distribution. Unless the shareholder instructs otherwise, with respect to Class A Shares, Class C Shares and Class Y Shares, the reinvestment plan is automatic. With respect to Class IC Shares and Class IB Shares, previous instructions regarding reinvestment of dividends and distributions will continue to apply until such shareholder changes his or her instructions.

Investor Profile

In light of the Fund's investment objective and principal investment strategies, the Fund may be appropriate for investors who:

An investment in the Fund may not be appropriate for all investors. The Fund is not intended to be a complete investment program, and investors should consider their long-term investment goals and financial needs when making an investment decision about the Fund. An investment in the Fund is intended to be a long-term investment, and the Fund should not be used as a trading vehicle.

Financial Highlights

The following schedules present financial highlights for one Share of the respective class of the Fund outstanding for the periods indicated. The ratio of expenses to average net assets listed in the tables below for each class of shares of the Fund are based on the average net assets of the Fund for each of the periods listed in the tables. To the extent that the Fund's average net assets decrease over the Fund's next fiscal year, such expenses can be expected to increase because certain fixed costs will be spreadover a smaller amount of assets. This information has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with the Fund's financial statements, is included in the Fund's Annual Report, which may be obtained from the Fund's website at www.invesco.com/us or by calling the telephone number on the last page of this Prospectus. This information should be read in conjunction with the financial statements and related notes included in the Fund's Annual Report.

The Fund

three classes of Shares - Class A Shares, Class C Shares and Class Y Shares. Class IB Shares and Class IC Shares are not continuously offered. The only new Class IB Shares and Class IC Shares to be issued are those Class IB Shares and Class IC Shares issued to satisfy dividend and capital gain reinvestment. The net proceeds from the sale of the Shares will be invested in accordance with the Fund's investment objective, investment strategies and policies or used for other operating purposes contemplated by this Prospectus. The Fund expects that it ordinarily will be able to invest the net proceeds from the sale of Shares within approximately 30 days of receipt.

The Fund's principal office is located at 11 Greenway Plaza, Houston, Texas 77046 and its telephone number is (800) 959-4246.

Investment Objective and Principal Investment Strategies of the Fund

Investment Objective

The Fund's investment objective is to provide a high level of current income, consistent with preservation of capital. The Fund's investment objective is fundamental and may not be changed by the Board of Trustees (the "Board") without the approval of a majority of the Fund's outstanding voting

securities, as defined in the 1940 Act. An investment in the Fund may not be appropriate for all investors and should not be considered a complete investment program. There is no assurance that the Fund will achieve its investment objective. You should carefully consider the risks of investing in the Fund. See "Principal Risks of Investing in the Fund."

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 Senior Loans. If the Fund's policy in the foregoing sentence changes, the Fund will notify shareholders in writing at least 60 days prior to implementation of the change and shareholders should consider whether the Fund remains an appropriate investment in light of the changes. Because Senior Loans have very large minimum investments, the Fund provides investors access to a market that normally is limited to institutional investors. Decisions to purchase or sell loans and securities are determined by the relative value considerations of the portfolio managers that factor in economic and credit-related fundamentals, market supply and demand, market dislocations and situation-specific opportunities. 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 purchase or sale of loans and securities may be related to a decision to alter the Fund's macro risk exposure, a need to limit or reduce the Fund's exposure to a particular security or issuer, degradation of an issuer's credit quality, or general liquidity needs of the Fund.

Description of Senior Loans

Interest rates and maturity. Interest rates on Senior Loans may adjust over different time periods, including daily, monthly, quarterly, semiannually or annually. The Fund may use interest rate swaps and other investment practices to shorten the effective interest rate adjustment period of Senior Loans. If the Fund does so, it generally considers the shortened period to be the adjustment period of the Senior Loan. Prime based and federal funds rate loans reset periodically when the underlying rate resets. LIBOR loans reset on set dates, typically every 30 to 90 days, but not to exceed one year. As short-term interest rates rise, interest payable to the Fund should increase. As short-term interest rates decline, interest payable to the Fund should decrease. The amount of time that will pass before the Fund experiences the effects of changing short-term interest rates will depend on the dollar-weighted average time until the next interest rate adjustment on the Fund's portfolio of Senior Loans. The interest rates are adjusted based on a base rate plus a premium or spread over the base rate. The base rate usually is LIBOR, the prime rate offered by one or more major United States banks (the "Prime Rate"), the certificate of deposit rate (the "CD Rate") or other base lending rates used by commercial lenders. LIBOR, as provided for in Loan Agreements, usually is an average of the interest rates quoted by several designated banks as the rates at which they pay interest to major depositors in the London interbank market on U.S. dollar denominated deposits. The Adviser believes that changes in short-term LIBOR rates are closely related to changes in the Federal Reserve federal funds rate, although the two are not technically linked. 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. The Prime Rate quoted by a major U.S. bank is generally the interest rate at which that bank is willing to lend U.S. dollars to the most creditworthy borrowers, although it may not be the bank's lowest available rate. The CD Rate, as provided for in Loan Agreements, usually is the average rate paid on large certificates of deposit traded in the secondary market.

When interest rates rise, the values of fixed income securities generally decline. When interest rates fall, the values of fixed income securities generally increase. The Fund expects the values of its Senior Loan investments to fluctuate less than the values of fixed rate, longer-term income securities in response to the changes in interest rates. Changes in interest rates can, however, cause some fluctuation in the Fund's net asset value.

The Fund expects that its Senior Loans will have stated maturities ranging from three to ten years, although the Fund has no policy limiting the maturity of Senior Loans that it purchases. Senior Loans usually have mandatory and optional prepayment provisions. Because of prepayments, the actual remaining maturity of Senior Loans may be considerably less than their stated maturity. Because the interest rates on Senior Loans adjust periodically, the Adviser believes that reinvestment by the Fund in Senior Loans after prepayment should not typically result in a significant reduction in interest payable to the Fund. Fees received by the Fund may even enhance the Fund's income. See "The Senior Loan Process" below.

Protective provisions of Senior Loans. Senior Loans usually have the most senior position in a Borrower's capital structure or share the senior position with other senior debt securities of the Borrower. This capital structure position generally gives holders of Senior Loans a priority claim on some or all of the Borrower's assets in the event of default. Most of the Fund's Senior Loan investments will be secured by specific assets of the Borrower. These Senior Loans will frequently be secured by all assets of the Borrower that qualify as collateral, such as trademarks, accounts receivable, inventory, buildings, real estate, franchises and common and preferred stock in its subsidiaries and affiliates. Collateral may also include guarantees or other credit support provided by affiliates of the Borrower. In some cases, a collateralized Senior Loan may be secured only by stock of the Borrower or its subsidiaries. The Loan Agreement may or may not require the Borrower to pledge additional collateral to secure the Senior Loan if the value of the initial collateral declines. In certain circumstances, the Loan Agreement may authorize the Agent to liquidate the collateral and to distribute the liquidation proceeds pro rata among the Lenders.

Senior Loans also have contractual terms designed to protect Lenders. Loan Agreements may include restrictive covenants that limit the activities of the Borrower. These covenants may include mandatory prepayment out of excess cash flows, restrictions on dividend payments, the maintenance of minimum financial ratios, limits on indebtedness and other financial tests. Breach of these covenants generally is an event of default and, if not waived by the Lenders, may give Lenders the right to accelerate principal and interest payments.

Covenant Lite Loans. Although loan investments are generally subject to certain restrictive covenants in favor of the investor, certain of the loans in which the Fund may invest may be issued or offered as "covenant lite" loans, which have few or no financial maintenance covenants. "Financial maintenance covenants" are those that require a borrower to maintain certain financial metrics during the life of the loan, such as maintaining certain levels of cash flow or limiting leverage. In the event of financial deterioration on the part of the borrower, these covenants are included to permit the lenders to renegotiate the terms of the loan, such as increasing the borrowing costs to the borrower, or to take other actions which would improve the position of the lender.

Borrowers. Borrowers operate in a variety of industries and geographic regions. The Fund will not invest 25% or more of its total assets in Borrowers that conduct their principal businesses in the same industry. Most Senior Loans are made to Borrowers that are organized or located in the U.S. The Fund may, however, invest up to 20% of its total assets, measured at the time of investment, in Senior Loans made to Borrowers that are organized or located in countries other than the U.S. The Fund also may hold non-U.S. dollar denominated Senior Loans or other securities received as part of a reorganization or restructuring. See "Principal Risks of Investing in the Fund - Foreign Investments Risk."

The capital structure of a Borrower may include Senior Loans, senior and junior subordinated debt, preferred stock and common stock. Senior Loans typically have the most senior claim on a Borrower's assets while common stock has the most junior claim. The proceeds of Senior Loans that the Fund will purchase typically will be used by Borrowers to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, debt refinancings and, to a lesser extent, for general operating and other purposes.

The Fund may purchase and retain in its portfolio Senior Loans of Borrowers that have filed for protection under the federal bankruptcy laws or that have had involuntary bankruptcy petitions filed against them by creditors. Because of the protective features of Senior Loans, the Adviser believes that Senior Loans of Borrowers that are experiencing, or are more likely to experience, financial difficulty may represent attractive investment opportunities. Investing in Senior Loans does, however, involve investment risk, and some Borrowers default on their Senior Loan payments. The Fund attempts to manage these risks through selection of a varied portfolio of Senior Loans and analyses and monitoring of Borrowers.

The Fund generally invests in a Senior Loan if, in the Adviser's judgment, the Borrower can meet its payment obligations and the Senior Loan meets the credit standards established by the Adviser. The Adviser performs its own independent credit analysis on each Borrower and on the collateral securing each Senior Loan. The Adviser considers the nature of the industry in which the Borrower operates, the nature of the Borrower's assets and the general quality and creditworthiness of the Borrower.

The Adviser constructs the Fund's investment portfolio using a process that focuses on obtaining access to the widest possible range of potential investments available in the market, legal review of the documents for loans and on-going credit analysis of the Borrowers. In constructing the portfolio, the Adviser analyzes each Borrower to determine its earnings potential and other factors indicating the sustainability of earnings growth.

The Adviser will consider selling a Senior Loan if, among other things, (1) unfavorable industry trends, poor performance, or a lack of access to capital cause the Borrower to fail to meet its planned objectives; or (2) more attractive investment opportunities are found. There can be no assurance that the Adviser's analysis will disclose all factors that may impair the value of a Senior Loan. You should expect the Fund's net asset value to fluctuate as a result of changes in the credit quality of Borrowers and other factors. A serious deterioration in the credit quality of a Borrower could cause a permanent decrease in the Fund's net asset value. See "Principal Risks of Investing in the Fund - Borrower Credit Risk."

There is no minimum rating or other independent evaluation of a Borrower or its securities limiting the Fund's investments. Although a Senior Loan may not be rated by any rating agency at the time the Fund purchases the Senior Loan, rating agencies have become more active in rating Senior Loans, and at any given time a substantial portion of the Senior Loans in the Fund's portfolio may be rated. There is no limit on the percentage of the Fund's assets that may be invested in Senior Loans that are rated below investment grade or that are unrated but deemed by the Adviser to be of comparable quality. The lack of a rating does not necessarily imply that a Senior Loan is of lesser investment quality; notwithstanding, such unrated securities may be of any credit quality, and may be below investment grade quality.

The following table sets forth the percentage of the Fund's Senior Loan obligations invested in rated and unrated obligations (using the higher of S&P or Moody's rating categories), based on valuations as of February 28, 2022:

Rated Obligations
AA/A	0.00%
BBB/Baa:	2.66%
BB/Ba:	16.91%
B/B:	62.11%

Rated Obligations
CCC/Caa:	8.94%
CC/Ca:	0.69%
Unrated Obligations:	8.69%
Total	100.00%

The Senior Loan Process

Senior Loans generally are negotiated between a Borrower and several Lenders represented by one or more Lenders acting as Agent of all the Lenders. The Agent is responsible for negotiating the Loan Agreement that establishes the terms and conditions of the Senior Loan and the rights of the Borrower and the Lenders. The Agent is paid a fee by the Borrower for its services.

The Agent generally is required to administer and manage the Senior Loan on behalf of other Lenders. When evaluating Senior Loans, the Adviser may consider, and may rely in part on, analysis performed by the Agent and other Lenders. This analysis may include an evaluation of the value and sufficiency of any collateral securing Senior Loans. As to collateralized Senior Loans, the Agent usually is required to monitor the collateral. The Agent may rely on independent appraisals of specific collateral. The Agent need not, however, obtain an independent appraisal of assets pledged as collateral in all cases. The Agent generally is also responsible for determining that the Lenders have obtained a perfected security interest in the collateral securing a Senior Loan.

The Fund normally relies on the Agent to collect principal of and interest on a Senior Loan. Furthermore, the Fund also relies in part on the Agent to monitor compliance by the Borrower with the restrictive covenants in the Loan Agreement and to notify the Fund (or the Lender from whom the Fund has purchased a participation) of any adverse change in the Borrower's financial condition. The Fund will not purchase interests in Senior Loans unless the Agent, Lender and any other person positioned between the Fund and the Borrower has entered into an agreement that provides for the holding of assets in safekeeping for, or the prompt disbursement of assets to, the Fund. Insolvency of the Agent or other persons positioned between the Fund and the Borrower could result in losses for the Fund. See "Principal Risks of Investing in the Fund - Senior Loan Risk."

The Fund may be required to pay and may receive various fees and commissions in connection with purchasing, selling and holding interests in Senior Loans. The fees normally paid by Borrowers include three primary types: facility fees, commitment fees and prepayment penalties. Facility fees are paid to Lenders when a Senior Loan is originated. Commitment fees are paid to Lenders on an ongoing basis based on the unused portion of a Senior Loan commitment. Lenders may receive prepayment penalties when a Borrower prepays a Senior Loan. The Fund receives these fees directly from the Borrower if the Fund is an Original Lender (as defined below) or, in the case of commitment fees and prepayment penalties, if the Fund acquires an Assignment (as defined below). Whether the Fund receives a facility fee in the case of an Assignment, or any fees in the case of a Participation (as defined below), depends on negotiations between the Fund and the Lender selling such interests. When the Fund buys an Assignment, it may be required to pay a fee to the Lender selling the Assignment, or to forgo a portion of interest and fees payable to the Fund. Occasionally, the assignor pays a fee to the assignee. A Lender selling a Participation to the Fund may deduct a portion of the interest and any fees payable to the Fund as an administrative fee. The Fund may be required to pass along to a person that buys a Senior Loan from the Fund a portion of any fees to which the Fund is entitled.

The Fund may have obligations under a Loan Agreement, including the obligation to make additional loans in certain circumstances.

Types of Senior Loan Investments

The Fund may act as one of a group of Lenders originating a Senior Loan (an "Original Lender"), may purchase assignments or novations ("Assignments") of portions of Senior Loans from third parties and may

invest in participations ("Participations") in Senior Loans. Senior Loans also include certain senior debt obligations that are in the form of notes rather than Loan Agreements and certain structured products with rates of return determined by reference to the total rate of return on one or more Senior Loans referenced in such products. All of these interests in Senior Loans are sometimes referred to simply as Senior Loans.

Original Lender. When the Fund acts as an Original Lender, it may participate in structuring the Senior Loan. When the Fund is an Original Lender, it will have a direct contractual relationship with the Borrower, may enforce compliance by the Borrower with the terms of the Loan Agreement and may have rights with respect to any funds acquired by other Lenders through set-off. Lenders also have full voting and consent rights under the applicable Loan Agreement. Action subject to Lender vote or consent generally requires the vote or consent of the holders of some specified percentage of the outstanding principal amount of the Senior Loan. Certain decisions, such as reducing the amount of interest on or principal of a Senior Loan, releasing collateral, changing the maturity of a Senior Loan or a change in control of the Borrower, frequently require the unanimous vote or consent of all Lenders affected. The Fund will never act as the Agent or principal negotiator or administrator of a Senior Loan.

Assignments. The purchaser of an Assignment typically succeeds to all the rights and obligations under the Loan Agreement of the assigning Lender and becomes a Lender under the Loan Agreement. Assignments may, however, be arranged through private negotiations, and the rights and obligations acquired by the purchaser of an Assignment may differ from, and be more limited than, those held by the assigning Lender.

Participations. The Fund presently does not intend to invest more than 5% of its net assets in Participations in Senior Loans. When the Fund purchases a Participation in a Senior Loan, the Fund will usually have a contractual relationship only with the Lender selling the Participation and not with the Borrower. The Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the Participation and only upon receipt by the Lender of such payments from the Borrower.

As a result, the Fund may assume the credit risk of both the Borrower and the Lender selling the Participation. In the event of insolvency of the Lender selling a Participation, the Fund may be treated as a general creditor of the Lender.

The Fund has taken the following measures in an effort to minimize these risks. The Fund will only acquire Participations if the Lender selling the Participation and any other persons positioned between the Fund and the Lender (i) has, at the time of investment, outstanding debt or deposit obligations rated investment grade by a rating agency or that are determined by the Adviser to be of comparable quality and (ii) has entered into an agreement which provides for the holding of assets in safekeeping for, or the prompt disbursement of assets to, the Fund.

The Fund generally will not have the right to enforce compliance by the Borrower with the Loan Agreement, nor rights to any funds acquired by other Lenders through set-off against the Borrower. In addition, when the Fund holds a Participation in a Senior Loan, it may not have the right to vote on whether to waive enforcement of any restrictive covenant breached by a Borrower. Lenders voting in connection with a potential waiver of a restrictive covenant may have interests different from those of the Fund and may not consider the interests of the Fund. The Fund may not benefit directly from the collateral supporting a Senior Loan in which it has purchased the Participation, although Lenders that sell Participations generally are required to distribute liquidation proceeds received by them pro rata among the holders of such Participations.

Senior Debt Securities. The Fund may invest up to 5% of its total assets in certain senior debt securities that are in the form of notes rather than Loan Agreements. The Fund will only purchase senior debt securities if (i) the senior debt securities represent the only form of senior debt financing of the Borrower or (ii) the senior debt securities are pari passu with other

Senior Loans in the capital structure of a Borrower with respect to collateral. There may be no person performing the role of the Agent for senior debt securities and, as a result, the Fund may be more dependent on the ability of the Adviser to monitor and administer the Senior Loans underlying these senior debt securities.

Senior debt securities will be treated as Senior Loans for purposes of the Fund's policy of normally investing at least 80% of its net assets in Senior Loans.

Structured products. The Fund also may invest up to 10% of its total assets in structured notes, credit- linked notes ("CLNs"), collateralized loan obligations ("CLOs"), collateralized debt obligations ("CDOs"), credit default swaps ("CDS") and other types of structured investments (referred to collectively as "structured products") to enhance the yield on its portfolio or to increase income available for distributions or for other non-hedging purposes. A structured note is a derivative security that has one or more special features, such as an interest rate based on a spread over an index or a benchmark interest rate, or other reference indicator, that may or may not correlate to the total rate of return on one or more underlying investments (such as Senior Loan interests) referenced in such notes. A CDS is an agreement between two parties to exchange the credit risk of a particular issuer or reference entity. In a CDS transaction, a buyer pays periodic fees in return for a payment by the seller which is contingent upon an adverse credit event occurring in the underlying issuer or reference entity. The seller collects periodic fees from the buyer and profits if the credit of the underlying issuer or reference entity remains stable or improves while the swap is outstanding, but the seller in a CDS contract would be required to pay an agreed upon amount to the buyer in the event of an adverse credit event in the reference entity. A buyer of a CDS is said to buy protection whereas a seller of a CDS is said to sell protection. When the Fund buys a CDS, it is utilizing the swap for hedging purposes similar to other hedging strategies described herein, see also "Other Important Investment Policies - Derivative Transactions." When the Fund sells a CDS, it is utilizing the swap to enhance the yield on its portfolio to increase income available for distribution or for other non-hedging purposes. CLNs, CLOs and CDOs are discussed further below under "Other Important Investment Policies." Generally, investments in structured products are interests in entities organized and operated for the purpose of restructuring the investment characteristics of underlying investment interests or securities. This type of restructuring generally involves the deposit with or purchase by an entity of the underlying investments (such as Senior Loan interests) and the issuance by that entity of one or more classes of securities backed by, or representing interests in, the underlying investments or referencing an indicator related to such investments. The cash flow or rate of return on the underlying investments may be apportioned among the newly issued securities to create different investment characteristics, such as varying maturities, credit quality, payment priorities and interest rate provisions. The cash flow or rate of return on a structured product may be determined by applying a multiplier to the rate of total return on the underlying investments or referenced indicator. Application of a multiplier is comparable to the use of financial leverage, a speculative technique.

Leverage magnifies the potential for gain and the risk of loss. As a result, a relatively small decline in the value of the underlying investments or referenced indicator could result in a relatively large loss in the value of a structured product. Holders of structured products bear risks of the underlying index or reference obligation and are subject to counterparty risk. Structured products where the rate of return is determined by reference to a Senior Loan will be treated as Senior Loans for purposes of the Fund's policy of normally investing at least 80% of its net assets in Senior Loans.

The Fund may have the right to receive payments to which it is entitled only from the structured product, and generally does not have direct rights against the Borrower. The Fund generally will not have the right to enforce compliance by the Borrower with the Loan Agreement, nor rights to any

funds acquired by other Lenders through set-off against the Borrower. In addition, when the Fund holds a structured product derived from a Senior Loan, it may not have the right to vote on whether to waive enforcement of any restrictive covenant breached by a Borrower. Lenders voting in connection with a potential waiver of a restrictive covenant may have interests different from those of the Fund and may not consider the interests of the Fund.

Other Important Investment Policies

The Fund may invest up to 20% of its total assets, measured at the time of investment, in Senior Loans made to Borrowers that are organized or located in countries other than the U.S., and, during normal market conditions, the Fund may invest up to 20% of its total assets in any combination of (1) warrants and equity securities (including common stocks, preferred stocks, rights and securities convertible into common stock), (2)high quality short-term debt securities, (3) other debt securities, including high-yield bonds and junior debt securities, (4) credit-linked deposits and (5) Treasury Inflation Protected Securities ("U.S. TIPS") and other inflation- indexed bonds issued by the U.S. government, its agencies or instrumentalities. The Fund also may convert a warrant into the underlying security. Although the Fund generally will acquire interests in warrants, equity securities and junior debt securities only when the Adviser believes that the value being given by the Fund is substantially outweighed by the potential value of such interests, investment in warrants, equity securities and junior debt securities entails certain risks in addition to those associated with investments in Senior Loans, including the potential for increasing fluctuations in the Fund's net asset value. The Fund's equity investments may include those received as part of a reorganization or restructuring. Any warrants, equity securities and junior debt securities held by the Fund will not be treated as Senior Loans and thus will not count toward the Fund's investment policy in which at least 80% of the Fund's net assets that normally will be invested in Senior Loans.

High quality, short-term debt securities in which the Fund may invest include commercial paper rated at least in the top two rating categories by S&P or Moody's, or unrated commercial paper considered by the Adviser to be of similar quality; interests in short-term loans of Borrowers having short-term debt obligations rated or a short-term credit rating at least in such top two rating categories, or having no rating but determined by the Adviser to be of comparable quality; certificates of deposit and bankers' acceptances; and securities issued or guaranteed by the U.S. government, its agencies or instrumentalities. These securities may pay interest at adjustable rates or at fixed rates. If the Adviser determines that market conditions temporarily warrant a defensive investment policy, the Fund may invest, subject to its ability to liquidate its relatively illiquid portfolio of Senior Loans, up to 100% of its assets in cash and high quality, short-term debt securities.

Credit-linked deposits are deposits by lenders, such as the Fund, to support the issuance of letters of credit to the Borrower. The Fund receives from the bank issuing such letters of credit an agreed upon rate of return in exchange for its deposit. There are risks associated with credit-linked deposits, including the credit risk of the bank which maintains the deposit account as well as the credit risk of the borrower. The Fund bears the risk of possible loss of its principal investment, in addition to the periodic interest payments that are expected to be received for the duration of the Fund's investment in the credit-linked deposit.

U.S. TIPS are fixed income securities issued by the U.S. Department of the Treasury, the principal amounts of which are adjusted daily based upon changes in the rate of inflation (currently represented by the non-seasonally adjusted Consumer Price Index for All Urban Consumers (the "CPI-U")). The Fund may purchase U.S. TIPS or other inflation-indexed bonds issued by the U.S. government, its agencies or instrumentalities of any maturity. U.S. TIPS pay interest on a periodic basis, equal to a fixed interest rate applied to the inflation-adjusted principal amount. The interest rate on these bonds is fixed at issuance, but over the life of the bond, this interest may be paid on an

increasing or decreasing principal value that has been adjusted for inflation. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed even during a period of deflation. However, because the principal amount of U.S. TIPS would be adjusted downward during a period of deflation, the Fund will be subject to deflation risk with respect to its investments in these securities. In addition, the current market value of the bonds is not guaranteed, and will fluctuate. If the Fund purchases U.S. TIPS in the secondary market whose principal values have been adjusted upward due to inflation since issuance, the Fund may experience a loss if there is a subsequent period of deflation. If inflation is lower than expected during the period the Fund holds U.S. TIPS, the Fund may earn less on the security than on a conventional bond. The Fund may invest in inflation-indexed securities issued by the U.S. government, its agencies or instrumentalities with other structures or characteristics as such securities become available in the market.

The Fund can invest in structured notes and CLNs. A structured note is a derivative security that has one or more special features, such as an interest rate based on a spread over an index or a benchmark interest rate, or other reference indicator, that may or may not correlate to the total return of one or more underlying investments (such as Senior Loan interests) referenced in such notes. CLNs are securities structured and issued by an issuer, which may be a bank, banker or special purpose vehicle. The CLN's price or coupon is linked to the performance of the reference asset of the second party. Generally, the CLN holder receives either a fixed or floating coupon rate during the life of the CLN and par at maturity. The cash flows are dependent on specified credit-related events. Should the second party default or declare bankruptcy, the CLN holder will receive an amount equivalent to the recovery rate and may not receive any compensation. In return for these risks, the CLN holder receives a higher yield. The Fund can use structured notes and CLNs to enhance the yield on its portfolio or to increase income available for distributions or for other non-hedging purposes.

In anticipation of or in response to market, economic, political, or other conditions, the Fund's portfolio managers may temporarily use a different investment strategy for defensive purposes. 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.

Financial Leverage. The Fund may utilize financial leverage (i) to provide the Fund with additional liquidity to meet its obligations to repurchase its Shares pursuant to its repurchase offers and (ii) for investment purposes (i.e., to use such financial leverage to purchase additional portfolio securities consistent with the Fund's investment objective and primary investment strategy) to benefit the Fund's Common Shares. Generally speaking, if the Fund can invest the proceeds from financial leverage (i.e., money from borrowings or issuing preferred shares) in portfolio securities that have higher rates of return than the costs of such financial leverage and other expenses of the Fund, then the holders of Common Shares would have a net benefit. The Fund's policy on financial leverage allows the Fund to use financial leverage in the form of borrowings and/or preferred shares to the maximum extent allowable under the 1940 Act. The Adviser will regularly review the Fund's use of financial leverage (i.e., the relative costs and benefits of leverage on the Fund's Common Shares) and review the alternative means to achieve leverage (i.e., the relative benefits and costs of borrowing versus issuing preferred shares).

Under the 1940 Act, a fund is not permitted to issue debt unless immediately after such incurrence the fund has an asset coverage of at least 300% of the aggregate outstanding principal balance of the indebtedness (i.e., such indebtedness may not exceed 33 1/3% of the

fund's total assets). Additionally, under the 1940 Act, a fund may not declare any dividend or other distribution upon any class of its capital shares, or purchase any such capital shares, unless the aggregate indebtedness of the fund has, at the time of the declaration of such dividend or distribution, or at the time of any such purchase, an asset coverage of at least 300% after deducting the amount of such dividend, distribution or purchase price, as the case may be. Investments in derivative instruments will not be considered the issuance of debt for purposes of the foregoing limitations if the Fund "covers" the resulting obligation in accordance with the 1940 Act and SEC guidance. Under the 1940 Act, a fund is not permitted to issue preferred shares unless immediately after such issuance the net asset value of the fund's portfolio is at least 200% of the liquidation value of the outstanding preferred shares (i.e., such liquidation value may not exceed 50% of the Fund's total assets). In addition, a fund is not permitted to declare any cash dividend or other distribution on its common shares unless, at the time of such distribution, the net asset value of the fund's portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of such liquidation value. If using a combination of borrowing and issuing preferred shares, the maximum allocable leverage will be between 300% and 200% based on the relative amounts borrowed and preferred shares issued.

Effect of Leverage. The Fund has entered into a revolving credit and security agreement pursuant to which the lenders will provide the Fund with up to $180 million in advances, subject to a variable interest rate. Assuming an weighted average interest rate of 1.04% (which is the rate of the Fund's outstanding borrowings as of February 28, 2022) and the use of leverage in an amount equal to 17.38% of the Fund's total assets (as of February 28, 2022), the incremental income generated by the Fund's portfolio (net of estimated expenses including expenses related to the use of leverage) must exceed approximately 1.00% to cover such interest expense. These numbers are merely estimates used for illustration. The amount of leverage used by the Fund as well as actual interest expenses on the Fund's outstanding borrowings may vary and may be higher or lower than the above estimates.

The following table is designed to illustrate the effect on return to a holder of the Fund's Common Shares of the leverage created by the Fund's use of borrowing, using the weighted average interest rate of 1.04%, (which is the rate of the Fund's outstanding borrowings as of February 28, 2022 as noted above, however, the Fund's outstanding borrowings are subject to a variable interest rate and may change up or down over time) assuming the Fund has used leverage by borrowing an amount equal to 17.52% of the Fund's total assets (as of February 28, 2022) and assuming hypothetical annual returns (net of expenses) on the Fund's portfolio of minus 10% to plus 10%. As the table shows, leverage generally increases the return to Common Shareholders when portfolio return is positive and decreases return when the portfolio return is negative. Actual returns may be greater or less than those appearing in the table.

Assumed portfolio return, Net of expenses	(10)%	(5)%	0%	5%	10%
Corresponding return to common shareholders	(11.70)%	(5.95)%	(0.21)%	5.54%	11.28%

The purpose of the table is to assist investors in understanding the effects of financial leverage. The figures in the table are hypothetical and actual returns may be greater or lesser than those appearing in the table.

The SEC has adopted a new regulatory framework governing the use of derivatives by registered investment companies ("Rule 18f-4"), as further discussed in the SAI. This new regulatory framework will also eliminate the asset segregation and coverage framework currently used by the Fund to comply with Section 18 of the 1940 Act in connection with derivatives and

certain other financing transactions. As the Fund transitions into compliance with Rule 18f-4, the Fund's approach to asset segregation and coverage requirements described in this prospectus and the SAI may be impacted.

Derivative Transactions. The Fund can invest in derivative instruments including swap contracts, futures contracts, and forward foreign currency contracts. A derivative is a financial instrument whose performance is derived at least in part from the performance of an underlying index, security or asset. The values of certain derivatives can be affected dramatically by even small market movements, sometimes in ways that are difficult to predict. There are many different types of derivatives, with many different uses. The Fund can enter into these transactions to seek to preserve a return on a particular investment or portion of its portfolio, and may also enter into such transactions to seek to protect against decreases in the anticipated rate of return on floating or variable rate financial instruments the Fund owns or anticipates purchasing at a later date, or for other risk management strategies such as managing the effective dollar-weighted average duration of the Fund's portfolio. In addition, the Fund may also engage in hedging transactions to seek to protect the value of its portfolio against declines in net asset value resulting from changes in interest rates or other market changes. Market conditions will determine whether and in what circumstances the Fund would employ any of the techniques described below. The Fund will incur brokerage and other costs in connection with its derivative transactions.

A swap contract is an agreement between two parties pursuant to which the parties exchange payments at specified dates on the basis of a specified notional amount, with the payments calculated by reference to specified securities, indexes, reference rates, commodities, currencies or other assets. The notional amount of a swap is based on the nominal or face amount of a reference asset that is used to calculate payments made on that swap; the notional amount typically is not exchanged between counterparties. The parties to the swap use variations in the value of the underlying asset to calculate payments between them through the life of the swap. The Fund can use swap contracts, including interest rate swaps, to hedge or adjust its exposure to interest rates, and currency swaps, to hedge its exposure to foreign currencies. The Fund can also use swap contracts, including CDS, to enhance the yield on its portfolio or to increase income available for distributions or for other non-hedging purposes.

The Fund may enter into interest rate swaps or purchase or sell interest rate caps or floors. The Fund will not sell interest rate caps or floors that it does not own. Interest rate swaps involve the exchange by the Fund with another party of their respective obligations to pay or receive interest, e.g., an exchange of an obligation to make floating rate payments for an obligation to make fixed rate payments. For example, the Fund may seek to shorten the effective interest rate redetermination period of a Senior Loan in its portfolio for which the Borrower has selected an interest rate redetermination period of one year. The Fund could exchange the Borrower's obligation to make fixed rate payments for one year for an obligation to make payments that readjust monthly. In such event, the Fund would consider the interest rate redetermination period of such Senior Loan to be the shorter period.

The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payments of interest at the difference of the index and the predetermined rate on a notional principal amount (the reference amount with respect to which interest obligations are determined, although no actual exchange of principal occurs) from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest at the difference of the index and the predetermined rate on a notional principal amount from the party selling such interest rate floor. The Fund will not enter into swaps, caps or floors if, on a net basis, the aggregate notional principal amount with respect to such agreements exceeds the net assets of the Fund.

In circumstances in which the Adviser anticipates that interest rates will decline, the Fund might, for example, enter into an interest rate swap as the floating rate payor or, alternatively, purchase an interest rate floor. In the case of purchasing an interest rate floor, if interest rates declined below the floor rate, the Fund would receive payments from its counterparty which would wholly or partially offset the decrease in the payments it would receive in respect of the portfolio assets being hedged. In the case where the Fund purchases such an interest rate swap, if the floating rate payments fell below the level of the fixed rate payment set in the swap agreement, the Fund's counterparty would pay the Fund amounts equal to interest computed at the difference between the fixed and floating rates over the notional principal amount. Such payments would offset or partially offset the decrease in the payments the Fund would receive in respect of floating rate portfolio assets being hedged.

The successful use of swaps, caps and floors to preserve the rate of return on a portfolio of financial instruments depends on the Adviser's ability to predict correctly the direction and extent of movements in interest rates. Although the Fund believes that use of the hedging and risk management techniques described above will benefit the Fund, if the Adviser's judgment about the direction or extent of the movement in interest rates is incorrect, the Fund's overall performance would be worse than if it had not entered into any such transactions. For example, if the Fund had purchased an interest rate swap or an interest rate floor to hedge against its expectation that interest rates would decline but instead interest rates rose, the Fund would lose part or all of the benefit of the increased payments it would receive as a result of the rising interest rates because it would have to pay amounts to its counterparty under the swap agreement or would have paid the purchase price of the interest rate floor.

The Fund will usually enter into interest rate swaps on a net basis, i.e., where the two parties make net payments with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The net amount of the excess, if any, of the Fund's obligations over its entitlements with respect to each interest rate swap will be accrued and an amount of cash, liquid securities or liquid Senior Loans having an aggregate net asset value at least equal to the accrued excess will be maintained in a segregated account by the Fund's custodian. If the Fund enters into a swap on other than a net basis, the Fund will maintain in the segregated account the full amount of the Fund's obligations under each such swap. Accordingly, the Fund does not treat swaps as senior securities. The Fund may enter into swaps, caps and floors with member banks of the Federal Reserve System, members of the New York Stock Exchange or other entities determined by the Adviser, pursuant to procedures adopted and reviewed on an ongoing basis by the Board of Trustees, to be creditworthy. If a default occurs by the other party to such transaction, the Fund will have contractual remedies pursuant to the agreements related to the transaction, but such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund's rights as a creditor. The swap market has grown substantially in recent years with a large number of banks and financial services firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid. Caps and floors are more recent innovations and they are less liquid than swaps. There can be no assurance, however, that the Fund will be able to enter into interest rate swaps or to purchase interest rate caps or floors at prices or on terms the Adviser believes are advantageous to the Fund. In addition, although the terms of interest rate swaps, caps and floors may provide for termination, there can be no assurance that the Fund will be able to terminate an interest rate swap or to sell or offset interest rate caps or floors that it has purchased.

A futures contract is a standardized agreement between two parties to buy or sell a specified quantity of an underlying asset at a specified price at a specified future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying asset. Futures contracts are bilateral agreements, with both the purchaser and the seller

equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled by purchasing an offsetting contract, physically delivering the underlying asset on the settlement date or paying a cash settlement amount on the settlement date. The Fund can use currency futures to hedge its exposure to foreign currencies. Currency futures contracts are traded on exchanges and have standard contract sizes and delivery dates. Most currency futures contracts call for payment or delivery in U.S. dollars.

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 mitigate the risk of foreign currency exposure. Spot contracts allow for prompt delivery and settlement at the rate prevailing in the currency exchange market at the time. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to modify exposure to a particular currency.

New financial products continue to be developed, and the Fund may invest in any such products to the extent consistent with its investment objective and the regulatory and federal tax requirements applicable to investment companies.

When Issued and Delayed Delivery Transactions. The Fund may also purchase and sell interests in Senior Loans and other portfolio securities on a when issued and delayed delivery basis. No income accrues to the Fund on such interests or securities in connection with such purchase transactions prior to the date that the Fund actually takes delivery of such interests or securities. These transactions are subject to market fluctuation; the value of the interests in Senior Loans and other portfolio debt securities at delivery may be more or less than their purchase price, and yields generally available on such interests or securities when delivery occurs may be higher or lower than yields on the interests or securities obtained pursuant to such transactions. Because the Fund relies on the buyer or seller, as the case may be, to consummate the transaction, failure by the other party to complete the transaction may result in the Fund missing the opportunity of obtaining a price or yield considered to be advantageous. When the Fund is the buyer in such a transaction, however, it will maintain, in a segregated account with its custodian, cash, liquid securities or liquid Senior Loans having an aggregate value at least equal to the amount of such purchase commitments until payment is made. The Fund will make commitments to purchase such interests or securities on such basis only with the intention of actually acquiring these interests or securities, but the Fund may sell such interests or securities prior to the settlement date if such sale is considered to be advisable. To the extent the Fund engages in when issued and delayed delivery transactions, it will do so for the purpose of acquiring interests or securities for the Fund's portfolio consistent with the Fund's investment objective and policies and not for the purpose of investment leverage. No specific limitation exists as to the percentage of the Fund's assets which may be used to acquire securities on a when issued or delayed delivery basis.

Repurchase Agreements. The Fund may enter into repurchase agreements (a purchase of, and a simultaneous commitment to resell, a financial instrument at an agreed upon price on an agreed upon date) only with member banks of the Federal Reserve System and member firms of the

New York Stock Exchange. When participating in repurchase agreements, the Fund buys securities from a vendor, e.g., a bank or brokerage firm, with the agreement that the vendor will repurchase the securities at a higher price at a later date. Such transactions afford an opportunity for the Fund to earn a return on available cash at minimal market risk, although the Fund may be subject to various delays and risks of loss if the vendor is unable to meet its obligation to repurchase. Under the

1940 Act, repurchase agreements are deemed to be collateralized loans of money by the Fund to the seller. In evaluating whether to enter into a repurchase agreement, the Adviser will consider carefully the creditworthiness of the vendor. If the member bank or member firm that is the party to the repurchase agreement petitions for bankruptcy or otherwise becomes subject to the U.S. Bankruptcy Code, the law regarding the rights of the Fund is unsettled. The securities underlying a repurchase agreement will be marked to market every business day so that the value of the collateral is at least equal to the value of the loan, including the accrued interest thereon, and the Adviser will monitor the value of the collateral. No specific limitation exists as to the percentage of the Fund's assets which may be used to participate in repurchase agreements.

Reverse Repurchase Agreements. Reverse repurchase agreements are agreements that involve the sale of securities held by the Fund to financial institutions such as banks and broker-dealers, with an agreement that the Fund will repurchase the securities at an agreed upon price and date (or upon demand). During the reverse repurchase agreement period, the Fund continues to receive interest and principal payments on the securities sold, but pays interest to the other party on the proceeds received. The Fund may employ reverse repurchase agreements (i) for temporary emergency purposes, such as to meet unanticipated net redemptions so as to avoid liquidating other portfolio securities during unfavorable market conditions; (ii) to cover short-term cash requirements resulting from the timing of trade settlements; or (iii) to take advantage of market situations where the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction.

Reverse repurchase agreements are a form of leverage and involve the risk that the market value of securities to be repurchased by the Fund may decline below the price at which the Fund is obligated to repurchase the securities, resulting in a requirement for the Fund to deliver margin to the other party in the amount of the related shortfall, or that the other party may default on its obligation so that the Fund is delayed or prevented from completing the transaction. Leverage may make the Fund's returns more volatile and increase the risk of loss. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use of the proceeds from the sale of the securities may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's obligation to repurchase the securities.

Anti-takeover provisions. The Fund's Declaration of Trust includes provisions that could limit the ability of other persons to acquire control of the Fund or to change the composition of its Board of Trustees. See "Description of Shares - Anti- Takeover Provisions in the Declaration of Trust."

Principal Risks of Investing in the Fund

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, 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, military conflict, 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.

Senior Loans and Other Loans Risk. There are a number of risks associated with an investment in Senior Loans including credit risk, interest rate risk, liquidity risk and prepayment risk. These risks are typically associated with debt securities. 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 is sensitive to, changes in government regulation and to economic downturns in the United States and abroad. These risks could cause the Fund to lose income or principal on a particular investment, which in turn could affect the Fund's returns.

In addition to the risks typically associated with debt securities, senior loans are also subject to the risk that a court could subordinate a senior loan, which typically holds a senior position in the capital structure of a borrower, to presently existing or future indebtedness or take other action detrimental to the holders of senior loans. Loans usually have mandatory and optional prepayment provisions. If a borrower prepays a loan, the Fund will have to reinvest the proceeds in other loans or financial assets that may pay lower rates of return.

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. In the event of a default, the Fund may have difficulty collecting on any collateral and would not have the ability to collect on any collateral for an uncollateralized loan. In addition, the lenders' security interest or their enforcement of their security under the loan agreement may be found by a court to be invalid or the collateral may be used to pay other outstanding obligations of the borrower. The Fund's access to collateral, if any, may be limited by bankruptcy, other insolvency laws, or by the type of loan the Fund has purchased. As a result, a collateralized loan may not be fully collateralized and can decline significantly in value.

Loan investments are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. These obligations 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. If the Fund voluntarily or involuntarily sold those types of loans, it might not receive the full value it expected.

Due to restrictions on transfers in loan agreements and the nature of the private syndication of loans including, for example, the lack of publicly-available information, some loans are not as easily purchased or sold as publicly-traded securities. Some loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when it wants to. The market price of investments in floating rate loans is expected to be less affected by changes in interest rates than fixed-rate investments because floating rate loans pay a floating rate of interest that will fluctuate as market interest rates do and therefore should more closely track market movements in interest rates.

Direct investments in loans and, to a lesser degree, investments in participation interests in or assignments of loans may be limited. A limited availability of loans could reduce the amount of attractive investments for the Fund. If market demand for loans increases, the interest paid by loans that the Fund holds may decrease. Due to the possible limited availability of loans in the market at a given time in which the Fund can invest, there is a risk that the Fund may not be able to invest a sufficient amount in loans at all times to meet its 80% asset investment requirement (including borrowings for investment purposes).

Compared to securities and to certain other types of financial assets, purchases and sales of loans take relatively longer to settle. This extended settlement process can (i) increase the counterparty credit risk borne by the Fund; (ii) leave the Fund unable to timely vote, or otherwise act with respect to, loans it has agreed to purchase; (iii) delay the Fund from realizing the proceeds of a sale of a loan; (iv) inhibit the Fund's ability to re-sell a loan that it has agreed to purchase if conditions change (leaving the Fund more exposed to price fluctuations); (v) prevent the Fund from timely collecting principal and interest payments; and (vi) expose the Fund to adverse tax or regulatory consequences. To the extent the extended loan settlement process gives rise to short-term liquidity needs, such as the need to satisfy redemption requests, the Fund may hold cash, sell investments or temporarily borrow from banks or other lenders. If the Fund undertakes such measures, the Fund's ability to pay redemption proceeds in a timely manner, as well as the Fund's performance, may be adversely affected.

If the Fund invests in a loan via a participation, the Fund will be exposed to the ongoing counterparty risk of the entity providing exposure to the loan (and, in certain circumstances, such entity's credit risk) in addition to the exposure the Fund has to the creditworthiness of the borrower. The terms of the participation may not entitle the Fund to all rights of a direct lender under the loan (for example, with respect to consent, voting or enforcement rights). Therefore, the Fund's rights under a participation interest for a particular loan may be more limited than the rights of the original lender or an investor who acquires an assignment of that loan. Where the Fund invests in a loan via a participation, the Fund generally will have no right of direct recourse against the borrower or ability to otherwise directly enforce the terms of the loan agreement.

In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower or an arranger, lenders will not have the protection of the anti-fraud provisions of the federal securities laws, as would be the case for bonds or stocks. Instead, in such cases, lenders generally rely on the contractual provisions in the loan agreement itself, and common-law fraud protections under applicable state law.

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.

Covenant Lite Loans Risk. Because covenant lite loans contain few or no financial maintenance covenants, covenant lite loans may not include terms that permit the lender of the loan to monitor the borrower's financial performance and, if certain criteria are breached, declare a default, which would allow the lender to restructure the loan or take other action intended to help mitigate losses. As a result, the Fund may experience relatively greater difficulty or delays in enforcing its rights on its holdings of covenant lite loans than its holdings of loans or securities with financial maintenance covenants, which may result in losses to the Fund, especially during a downturn in the credit cycle.

LIBOR Transition Risk. The Fund may have investments in financial instruments that utilize the London Interbank Offered Rate ("LIBOR") as the reference or benchmark rate for variable interest rate calculations. LIBOR is intended to measure the rate generally at which banks can lend and borrow from one another in the relevant currency on an unsecured basis. In the years following the 2008 financial crisis, the integrity of LIBOR was increasingly questioned because several banks contributing to its calculation were accused of rate manipulation and because of a general contraction in the unsecured interbank lending market. As a result, regulators and financial industry working groups in several jurisdictions have worked over the past several years to identify alternative reference rates ("ARRs") to replace LIBOR and to assist with the transition to the new ARRs. In connection with the transition, on March 5, 2021 the UK Financial Conduct Authority (FCA), the regulator that oversees LIBOR, announced that the majority of LIBOR rates would cease to be published or would no longer be representative on January 1, 2022. Consequently, the publication of most LIBOR rates ceased at the end of 2021, but a selection of widely used USD LIBOR rates continues to be published until June 2023 to allow for an orderly transition away from these rates. Additionally, key regulators have instructed banking institutions to cease entering into new contracts that reference these USD LIBOR settings after December 31, 2021, subject to certain limited exceptions.

There remains uncertainty and risks relating to the continuing LIBOR transition and its effects on the Fund and the instruments in which the Fund invests. For example, there can be no assurance that the composition or characteristics of any ARRs or financial instruments in which the Fund invests that utilize ARRs will be similar to or produce the same value or economic equivalence as LIBOR or that these instruments will have the same volume or liquidity. Additionally, although regulators have generally prohibited banking institutions from entering into new contracts that reference those USD LIBOR settings that continue to exist, there remains uncertainty and risks relating to certain "legacy" USD LIBOR instruments that were issued or entered into before December 31, 2021 and the process by which a replacement interest rate will be identified and implemented into these instruments when USD LIBOR is ultimately discontinued. The effects of such uncertainty and risks in "legacy" USD LIBOR instruments held by the Fund could result in losses to the Fund.

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.

High Yield Debt Securities (Junk Bond) Risk. The Fund's investments in high yield debt securities (commonly referred to as "junk bonds") and other lower-rated securities will subject the Fund to substantial risk of loss. These securities are considered to be speculative with respect to the issuer's ability to pay interest and principal when due and are more susceptible to default or decline in market value due to adverse economic, regulatory, political or company developments than higher rated or investment grade securities. Prices of high yield debt securities tend to be very volatile. These securities are less liquid than investment grade debt securities and may be difficult to sell at a desirable time or price, particularly in times of negative sentiment toward high yield securities.

Defaulted Securities Risk. Defaulted securities pose a greater risk that principal will not be repaid than non-defaulted securities. The Fund will generally not receive interest payments on defaulted securities and may incur costs to protect its investment. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale. Investments in defaulted securities and obligations of distressed issuers are considered speculative and the prices of these securities may be more volatile than non-defaulted securities.

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.

Changing Fixed Income Market Conditions Risk. The current low interest rate environment was created in part by the Federal Reserve Board (FRB) and certain foreign central banks keeping the federal funds and equivalent foreign rates near historical lows. Increases in the federal funds and equivalent foreign rates may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. In addition, decreases in fixed income dealer market-making capacity may persist in the future, potentially leading 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. In addition, because of changing central bank policies, the Fund may experience higher than normal shareholder redemptions which could potentially increase portfolio turnover and the Fund's transaction costs and potentially lower the Fund's performance returns.

Financial Services Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates, volatility in the financial markets, changes in domestic and foreign monetary policy, and changes in industry regulations, can have a disproportionate effect on companies in the financial services sector which could adversely affect the profitability of such companies. Financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them especially vulnerable to unstable economic conditions.

Asset-Backed Securities Risk. Asset-backed securities differ from conventional debt securities because principal is paid back over the life of the security rather than at maturity. Asset-backed securities are subject to prepayment or call risk, which is the risk that a borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Faster prepayments often happen when interest rates are falling. As a result, the Fund may reinvest these early payments at lower interest rates, thereby reducing the Fund's income. Asset-backed securities also are subject to extension risk. A rise in interest rates could reduce the rate of prepayments and extend the life of the asset-backed securities, causing the price of the asset-backed securities and the Fund's share price to fall.

Foreign Securities Risk. The value of the Fund's foreign investments may be adversely affected by political and social instability in the home countries of the issuers of the investments, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. 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. 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. Also, there may be less publicly available information about companies in certain foreign countries than about U.S. companies making it more difficult for the Adviser to evaluate those companies. The laws of certain countries may put limits on the Fund's ability to recover its assets held at a foreign bank if the foreign bank, depository or issuer of a security, or any of their agents, goes bankrupt. 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. Changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign

securities may also expose the Fund to time-zone arbitrage risk. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Unless the Fund has hedged its foreign currency exposure, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful. For instance, currency forward contracts, if used by the Fund, could reduce performance if there are unanticipated changes in currency exchange rates.

Emerging Market Securities Risk. Emerging markets (also referred to as developing markets) are generally subject to greater market volatility, political, social and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than more developed markets. In addition, companies operating in emerging markets may have greater concentration in a few industries resulting in greater vulnerability to regional and global trade conditions and also may be subject to lower trading volume and greater price fluctuations than companies in more developed markets. Unexpected market closures may also affect investments in emerging markets. Settlement procedures may differ from those of more established securities markets, and settlement delays may result in the inability to invest assets or dispose of portfolio securities in a timely manner. As a result there could be subsequent declines in value of the portfolio security, a decrease in the level of liquidity of the portfolio, or, if there is a contract to sell the security, a possible liability to the purchaser.

Such countries' economies may be more dependent on relatively few industries or investors that may be highly vulnerable to local and global changes. Emerging market countries may also have higher rates of inflation and more rapid and extreme fluctuations in inflation rates and greater sensitivity to interest rate changes. Further, companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries and, as a result, the nature and quality of such information may vary. Information about such companies may be less available and reliable and, therefore, the ability to conduct adequate due diligence in emerging markets may be limited which can impede the Fund's ability to evaluate such companies. In addition, certain emerging market countries have material limitations on Public Company Accounting Oversight Board ("PCAOB") inspection, investigation and enforcement capabilities, which hinder the ability to engage in independent oversight or inspection of accounting firms located in or operating in certain emerging markets; therefore, there is no guarantee that the quality of financial reporting or the audits conducted by audit firms of emerging market issuers meet PCAOB standards.

Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. Emerging market countries also may have less developed legal systems allowing for enforcement of private property rights and/or redress for injuries to private property (including bankruptcy, confiscatory taxation, expropriation, nationalization of a company's assets, restrictions on foreign ownership of local companies, restrictions on withdrawing assets from the country, protectionist measures and practices such as share blocking). Certain governments may require approval for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. The ability to bring and enforce actions in emerging market countries, or to obtain information needed to pursue or enforce such actions, may be limited and shareholder claims may be difficult or impossible to pursue. In addition, the taxation systems at the

federal, regional and local levels in emerging market countries may be less transparent and inconsistently enforced, and subject to sudden change.

Emerging market countries may have a higher degree of corruption and fraud than developed market countries, as well as counterparties and financial institutions with less financial sophistication, creditworthiness and/or resources. The governments in some emerging market countries have been engaged in programs to sell all or part of their interests in government-owned or controlled enterprises. However, in certain emerging market countries, the ability of foreign entities to participate in privatization programs may be limited by local law. There can be no assurance that privatization programs will be successful.

Other risks of investing in emerging market securities may include additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

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.

Derivatives Risk. A derivative is an instrument whose value 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, which are described below.

counterparty each day, if any, or otherwise holds instruments that offset the Fund's daily obligation under the derivatives instrument. This process is sometimes referred to as "cover." The amount of liquid assets needed as cover will fluctuate over time as the value of the derivative instrument rises and falls. If the value of the Fund's derivative positions or the value of the assets used as cover unexpectedly decreases, the Fund may be forced to segregate additional liquid assets as cover or sell assets at a disadvantageous time or price to meet its derivative obligations or to meet redemption requests, which could affect management of the Fund and the Fund's returns. As the Fund transitions into compliance with Rule 18f-4 under the Investment Company Act of 1940 (the "1940 Act"), with which compliance is required by August 19, 2022, the Fund's approach to asset segregation and coverage requirements may be impacted. On or after August 19, 2022, the Fund will no longer engage in "coverage" techniques with respect to derivatives transactions and will instead comply with the applicable requirements of Rule 18f-4. In certain market conditions, losses on derivative instruments can grow larger while the value of the Fund's other assets fall, resulting in the Fund's derivative positions becoming a larger percentage of the Fund's investments.

contracts involve the risk that anticipated currency movements will not be accurately predicted, causing the Fund to sustain losses on these contracts and to pay additional transaction costs.

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. An investment may be illiquid due to a lack of trading volume in the investment or if the investment is privately placed and not traded in any public market or is otherwise restricted from trading. 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.

Borrower Credit Risk. Senior Loans, like most other debt obligations, are subject to the risk of default. Default in the payment of interest or principal on a Senior Loan will result in a reduction in income to the Fund, a reduction in the value of the Senior Loan and a potential decrease in the Fund's net asset value. The risk of default will increase in the event of an economic downturn or a substantial increase in interest rates.

The Fund may acquire Senior Loans of Borrowers that are experiencing, or are more likely to experience, financial difficulty, including Senior Loans issued in highly leveraged transactions. The Fund may even acquire and

retain in its portfolio Senior Loans of Borrowers that have filed for bankruptcy protection. Because of the protective terms of Senior Loans, the Adviser believes that the Fund is more likely to recover more of its investment in a defaulted Senior Loan than would be the case for most other types of defaulted debt securities. Nevertheless, even in the case of collateralized Senior Loans, there is no assurance that sale of the collateral would raise enough cash to satisfy the Borrower's payment obligation or that the collateral can or will be liquidated. In the case of bankruptcy, liquidation may not occur and the court may not give Lenders the full benefit of their senior position. Uncollateralized Senior Loans involve a greater risk of loss.

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, 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. The Fund may underperform other funds that do not incorporate ESG factors or that use a different methodology to identify and/or incorporate ESG factors. 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.

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.

When-Issued, Delayed Delivery and Forward Commitment Risks.When-issued and delayed delivery transactions are subject to market risk as the value or yield of a security at delivery may be more or less than the purchase price or the yield generally available on securities when delivery occurs. In addition, the Fund is subject to counterparty risk because it relies on the buyer or seller, as the case may be, to consummate the transaction, and failure by the counterparty to complete the transaction may result in the Fund missing the opportunity of obtaining a price or yield considered to be advantageous. These transactions have a leveraging effect on the Fund because the Fund commits to purchase securities that it does not have to pay for until a later date. These investments therefore increase the Fund's overall investment exposure and, as a result, its volatility. Typically, no income accrues on securities the Fund has committed to purchase prior to the time delivery of the securities is made, although the Fund may earn income on securities it has set aside to cover these positions.

Inflation-Indexed Securities Risk. Inflation-indexed securities typically provide principal and interest payments that are adjusted over time to reflect a rise (inflation) or a drop (deflation) in the general price level for goods and services. Because of the inflation-adjustment feature, these securities typically have lower yields than traditional fixed-rate securities with similar maturities. The values of inflation-indexed securities generally fluctuate in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed securities, which could cause losses for the Fund. Conversely, if inflation

rises at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed securities. The Fund's income from its investments in inflation-indexed securities is likely to fluctuate considerably more than the income distributions of its investments in more traditional fixed-income securities.

Rule 144A Securities and Other Exempt Securities Risk. The Fund may invest in Rule 144A securities and other types of exempt securities, which are not registered for sale pursuant to an exemption from registration under the Securities Act of 1933, as amended. These securities are also known as privately issued securities, and typically may be resold only to qualified institutional buyers, or in a privately negotiated transaction, or to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Although such securities may be determined to be liquid in accordance with the requirements of Rule 22e-4 under the Investment Company Act of 1940, as amended, if there are an insufficient number of qualified institutional buyers interested in purchasing such securities at a particular time, the Fund may have difficulty selling such securities at a desirable time or price. As a result, the Fund's investment in such securities may be subject to increased liquidity risk. In addition, the issuers of Rule 144A securities may require their qualified institutional buyers (such as the Fund) to keep certain offering information confidential, which could adversely affect the ability of the Fund to sell such securities.

Repurchase Agreement Risk. Repurchase agreements expose the Fund to the risk that the counterparty defaults on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement. In this circumstance, the Fund could lose money if the underlying instruments used as collateral lose their value before they can be sold. These risks are magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.

Reverse Repurchase Agreement Risk. Reverse repurchase agreements involve the risk that the market value of securities to be repurchased may decline below the repurchase price resulting in a requirement for the Fund to deliver margin to the other party in the amount of the related shortfall, or that the other party may default on its obligation, resulting in the Fund being delayed or prevented from completing the transaction. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use of the proceeds from the sale of the securities may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's repurchase obligation. When the Fund engages in reverse repurchase agreements, changes in the value of the Fund's investments will have a larger effect on its share price than if it did not engage in these transactions due to the effect of leverage. Leverage will make the Fund's returns more volatile and increase the risk of loss. Additionally, interest expenses related to reverse repurchase agreements could exceed the rate of return on debt obligations and other investments held by the Fund, thereby reducing returns to shareholders.

No Trading Market for Shares. The Fund is a closed-end investment company designed primarily for long-term investors and not as a trading vehicle. While there is no restriction on transferring the Shares, the Fund does not intend to list the Shares for trading on any national securities exchange. There is no secondary trading market for Shares. An investment in the Shares is illiquid. There is no guarantee that you will be able to sell all of the Shares that you desire to sell in any repurchase offer by the Fund.

Collateralized Loan Obligations Risk. CLOs are subject to the risks of substantial losses due to actual defaults by underlying borrowers, which will be greater during periods of economic or financial stress. CLOs may also lose value due to collateral defaults and disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to CLO securities as a class. The risks of CLOs will be greater if the Fund invests in CLOs that hold loans of uncreditworthy borrowers or if the Fund holds

subordinate tranches of the CLO that absorb losses from the defaults before senior tranches. In addition, CLOs are subject to interest rate risk and credit risk.

Credit Linked Notes Risk. Risks of credit linked notes include those risks associated with the underlying reference obligation including but not limited to market risk, interest rate risk, credit risk, default risk and, in some cases, foreign currency risk. In the case of a credit linked note that is "funded," the par amount of the security will represent the maximum loss that could be incurred on the investment and no leverage is introduced. An investor in a credit linked note bears counterparty risk or the risk that the issuer of the credit linked note will default or become bankrupt and not make timely payment of principal and interest of the structured security. Credit linked notes may be less liquid than other investments and therefore harder to dispose of at the desired time and price. In addition, credit linked notes may be leveraged and, as a result, small changes in the value of the underlying reference obligation may produce disproportionate losses to the Fund.

Investing in Stocks Risk. Common stock represents an ownership interest in a company. It ranks below preferred stock and debt securities in claims for dividends and in claims for assets of the issuer in a liquidation or bankruptcy. Common stocks may be exchange-traded or over-the-counter securities. Over-the-counter securities may be less liquid than exchange-traded securities.

The value of the Fund's portfolio may be affected by changes in the stock markets. Stocks and other equity securities fluctuate in price in response to changes to equity markets in general. 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), their share values may fluctuate more in response to events affecting the market for those types of securities.

Repurchase Offer Risks. If the Fund repurchases more Shares than it is able to sell, the Fund's net assets may decline and its expense ratios may increase, and the Fund's ability to achieve its investment objective may be adversely affected. Moreover, this may force the Fund to sell assets it would not otherwise sell, and the Fund may be forced to dispose of Fund assets that may have declined in value. The Fund may borrow money to, among other things, finance repurchases of Shares. The rights of any lenders to the Fund to receive payments of interest on and repayments of principal of any borrowings will be senior to the rights of shareholders. The loan agreement for any borrowing likely will limit certain activities of the Fund, including the payment of dividends to holders of Shares in certain circumstances. Interest payments and fees incurred in connection with borrowings to finance repurchases of Shares will reduce the amount of net income available for payment to shareholders and may increase volatility of the net asset value of the Common Shares. See also the section above on "Financial Leverage Risk" and the section of the Prospectus entitled "Repurchase of Shares."

Management of the Fund

Board of Trustees

The management of the Fund, including general supervision of the duties performed by the Adviser, is the responsibility of the Fund's Board of Trustees.

Investment Adviser

Invesco Advisers, Inc. ("Invesco" or the "Adviser") is the Fund's investment adviser. The Adviser is an indirect wholly owned subsidiary of Invesco Ltd. Invesco Ltd. and its subsidiaries are an independent global investment management group. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, a successor in interest to multiple investment advisers, has been an investment adviser since 1976.

Advisory Agreement. The Fund retains the Adviser to manage the investment of its assets and to place orders for the purchase and sale of its portfolio securities. Under an investment advisory agreement between the Adviser and the Fund (the "Advisory Agreement"), the Fund pays the Adviser a monthly fee computed based upon an annual rate applied to the average daily net assets of the Fund as follows:

Average Daily Net Assets	% Per Annum
First $500 million	0.900%
Next $1 billion	0.850%
Next $1 billion	0.825%
Next $500 million	0.800%
Over $3 billion	0.775%

Applying this fee schedule, the Fund's effective advisory fee rate was 0.90% of the Fund's average daily net assets for the Fund's fiscal year ended February 28, 2022. The Fund's average daily net assets are determined by taking the average of all of the determinations of the net assets during a given calendar month. Such fee is payable for each calendar month as soon as practicable after the end of that month.

The Adviser furnishes offices, necessary facilities and equipment. The Fund pays all charges and expenses of its day-to-day operations, including service fees, distribution fees, custodian fees, legal and independent registered public accounting firm fees, the costs of reports and proxies to shareholders, compensation of trustees of the Fund (other than those who are affiliated persons of the Adviser or Invesco Distributors) and all other ordinary business expenses not specifically assumed by the Adviser.

Investment Sub-Adviser

Invesco Senior Secured Management, Inc. ("Invesco Senior Secured") serves as the Fund's investment sub-adviser. Invesco Senior Secured, an affiliate of the Adviser, is located at 225 Liberty Street, New York, New York 10281. Invesco Senior Secured has experience managing senior secured loans dating back to 1990. Invesco Senior Secured manages a broad array of portfolio types including retail mutual funds, commingled institutional funds, separate accounts and structured products for a variety of retail and institutional investors (both public and private). Invesco Senior Secured is responsible for the Fund's day-to-day management, including the Fund's investment decisions and the execution of securities transactions with respect to the Fund. The Adviser, not the Fund, pays sub-advisory fees, if any.

In addition, 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.

A discussion regarding the basis for the Board of Trustees' approval of the Advisory Agreement and Sub-Advisory Agreement is available in the Fund's Semiannual Report dated August 31, 2020.

Exclusion of Adviser from Commodity Pool Operator Definition. With respect to the Fund, the Adviser has claimed an exclusion from the definition of "commodity pool operator" (CPO) under the Commodity Exchange Act (CEA) and the rules of the Commodity Futures Trading Commission (CFTC) and, therefore, is not subject to CFTC registration or regulation as a CPO. In addition, the Adviser is relying upon a related exclusion from the definition of "commodity trading advisor" (CTA) under the CEA and the rules of the CFTC with respect to the Fund. The terms of the CPO exclusion require the Fund, among other things, to adhere to certain limits on its investments in "commodity interests." Commodity interests include commodity futures, commodity options and swaps, which in turn include non-deliverable forwards. The Fund is permitted to invest in these instruments as further described in the Fund's SAI. However, the Fund is not intended as a vehicle for trading in the commodity futures, commodity options or swaps markets. The CFTC has neither reviewed nor approved the Adviser's reliance on these exclusions, or the Fund, its investment strategies or this prospectus.

Portfolio management. Investment management decisions for the Fund are made by the investment management teams at Invesco and Invesco Senior Secured. The following individuals are jointly and primarily responsible for the day-to-day management of the Fund's portfolio.

More information on the portfolio managers may be found at www.invesco.com/us. The website is not part of the Prospectus.

The Fund's SAI provides additional information about the portfolio managers' investments in the Fund, a description of the compensation structure and information regarding other accounts managed.

Administrator

Invesco Advisers, Inc., the Fund's investment adviser, also serves as the Fund's Administrator. Pursuant to the administration agreement between the Fund and the Administrator (the "Administration Agreement"), the Administrator is responsible for providing or overseeing the provision of the following activities: (i) monitoring provisions of Loan Agreements and any Participations and Assignments and is responsible for recordkeeping for Senior Loans; (ii) arranging for the printing and dissemination of reports to shareholders; (iii) arranging for dissemination of the Fund's proxy and any repurchase offer materials to shareholders, and oversees the tabulation of proxies by the Fund's transfer agent; (iv) negotiating the terms and conditions under which custodian services are provided to the Fund and the fees to be paid by the Fund in connection therewith; (v) negotiating the terms and conditions under which dividend disbursing services are provided to the Fund, and the fees to be paid by the Fund in connection therewith, and reviews the provision of such services to the Fund; (vi) providing the Fund's dividend disbursing agent and custodian with such information as is required for them to effect payment of dividends and distributions and to implement the Fund's dividend reinvestment plan; (vii) making such reports and recommendations to the Board of Trustees as the trustees reasonably request; and (viii) providing shareholder services to holders or potential holders of the Fund's securities.

For the services rendered to the Fund and related expenses borne by the Administrator, the Fund pays the Administrator a fee, accrued daily and paid monthly, at the annualized rate of 0.25% of the Fund's average daily net assets.

Purchase of Shares

General

This Prospectus offers three classes of Shares of the Fund, designated as Class A Shares, Class C Shares and Class Y Shares, and describes two classes of Shares, designated as Class IB Shares and Class IC Shares, which are not continuously offered. Class A Shares and Class C Shares are available to all retail investors, including individuals, trusts, corporations, business and charitable organizations and retirement and benefits plans. Class Y shares are available to (i) investors who purchase through an account that is charged an asset-based fee or commission by a financial intermediary including through brokerage platforms, where a broker is acting as the investor's agent, that may require the payment by the investor of a commission and/or other form of compensation to that broker, that Invesco or its affiliate has approved to sell Class Y shares, (ii) defined contribution plans, defined benefit retirement plans, endowments or foundations, (iii) banks or bank trust departments acting on their own behalf or as trustee or manager for trust accounts, or (iv) any current, former or retired trustee, director, officer or employee (or immediate family members of a current, former or retired trustee, director, officer or employee) of any registered investment funds offered to retail investors advised by the Adviser ("Invesco Funds") or of Invesco Ltd. or any of its subsidiaries. In fee-based advisory programs, a financial intermediary typically charges each investor a fee based on the value of the investor's account in exchange for servicing that account. By offering multiple classes of Shares, the Fund permits each investor to choose the class of Shares that is most beneficial given the type of investor, the amount to be invested and the length of time the investor expects to hold the Shares. You should discuss with your authorized dealer which Share class is most appropriate for you. As described more fully below, each class of Shares offers a distinct structure of sales charges, distribution and service fees and other features (for example, the reduced or eliminated sales charges available for purchases of Class A Shares over $100,000 of the Fund or your cumulative ownership of Participating Funds) that are designed to address a variety of needs. Each class of Shares of the Fund represents an interest in the same portfolio of investments of the Fund and has the same rights except that (i) Class A Shares generally bear the sales charge expenses at the time of purchase while Class C Shares generally bear the sales charge expenses at the time of repurchase by the Fund and any expenses (including higher distribution fees and transfer agency costs) resulting from such early withdrawal charge arrangement and Class Y Shares, Class IB Shares and Class IC Shares are not subject to initial sales charges or early withdrawal charges, (ii) each class of Shares has exclusive voting rights with respect to approvals of any applicable distribution plan and any applicable service plan (each as described below), under which the class's distribution fee and/or service fee is paid, (iii) certain classes of Shares have different exchange privileges, (iv) certain classes of Shares are subject to a conversion feature and (v) certain classes of Shares have different shareholder service options available.

Pricing Fund Shares

The offering price of the Fund's Shares is based upon the Fund's net asset value per Share (plus sales charges, where applicable). Differences in net asset values per Share of each class of Shares are generally expected to be due to the daily expense accruals of the specified distribution and service fees and transfer agency costs applicable to such class of Shares and the differential in the dividends that may be paid on each class of Shares.

The net asset value per Share for each class of Shares of the Fund is determined and reported on the Fund's website once daily as of the close of trading on the New York Stock Exchange (the "Exchange") (generally 4:00 p.m., Eastern time) each day the Exchange is open for trading except on any day on which no purchase or repurchase orders are received or there is not a sufficient degree of trading in the Fund's portfolio securities such that the Fund's net asset value per Share might be materially affected. The Fund's

Board of Trustees reserves the right to calculate the net asset value per Share and adjust the offering price more frequently than once daily if deemed desirable. Net asset value per Share for each class is determined by dividing the value of the Fund's portfolio securities, cash and other assets (including accrued interest) attributable to such class, less all liabilities (including accrued expenses) attributable to such class, by the total number of Shares of the class outstanding. For more information about computing net asset value per Share, see the section entitled "Net Asset Value" in the Fund's Statement of Additional Information.

Determination of Net Asset Value

The price of the Fund's shares is the Fund's net asset value ("NAV") per share. The Fund's NAV per share shall be calculated within 48 hours prior to each sale of shares. The Fund values portfolio securities for which market quotations are readily available at market value. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day. The Fund values securities and assets for which market quotations are unavailable at their "fair value," which is described below. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

The Board has delegated day-to-day responsibility for implementing the portfolio valuation process to the Adviser, and has authorized the Adviser to utilize the independent third-party pricing services and independent third-party valuation services that have been approved by the Board. Independent pricing services will also use actuarial capabilities and modeling analysis to further validate fair prices specifically before and after key events.

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 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 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.

Domestic Exchange Traded Equity Securities. Market quotations are generally available and reliable for domestic exchange traded equity securities. If market quotations are not available or are unreliable, the Adviser will value the security at fair value in good faith using procedures approved by the Board.

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.

Futures and Options. Futures contracts are valued at the final settlement price set by the exchange on which they are principally traded. Options are valued on the basis of market quotations, if available.

Swap Agreements. Swap Agreements are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service are based on a model that may include end of day net present values, spreads, ratings, industry and company performance.

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.

The Manager conducts the valuation of the Fund's assets, pursuant to which NAV shall be determined, at all times consistent with US GAAP ("GAAP") and the 1940 Act. The Board, with the assistance of the Audit Committee, determines the fair value of the Fund's assets on at least a quarterly basis, in accordance with the terms of FASB Accounting Standards Codification Topic 820, Fair Value Measurement ("ASC 820").

GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment's assigned level:

Level 1 - Prices are determined using quoted prices in an active market for identical assets.

Level 2 - Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.

Level 3 - Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund's own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

Fair Value Pricing. Securities owned by the Fund are to be valued at current market value if market quotations are readily available. All other securities and assets of the Fund for which market quotations are not readily available are to be valued at fair value determined in good faith using procedures approved by the Board. An effect of fair value pricing may be to reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

Distribution Plan and Service Plan

The Fund has adopted a Distribution Plan with respect to each of its Class A Shares and Class C Shares and in so doing has agreed to comply with Rule 12b-1 under the 1940 Act as if the Fund were an open-end investment company. The Fund also has adopted a Service Plan with respect to each of its Class A Shares, Class C Shares and Class IC Shares. There is no Distribution Plan or Service Plan for Class Y Shares or Class IB Shares and no Distribution Plan for Class IC Shares. Under the Distribution Plan and the Service Plan, the Fund pays distribution fees in connection with the sale and distribution of Class A Shares and Class C Shares and service fees in connection with the provision of ongoing services to holders of Class A Shares, Class C Shares and Class IC Shares and the maintenance of such shareholders' accounts. For information on the fees paid pursuant to the Distribution Plan and Service Plan for Class A and Class C Shares, see "Class A Shares" and "Class C Shares," respectively. Class IC Shares are subject to a service fee of up to 0.25% of average daily net assets attributable to such class of Shares. The Fund's Board of Trustees has authorized the Fund to make service fee payments not to exceed 0.15% of the Fund's average daily net assets attributable to Class IC Shares for any fiscal year.

The amount of distribution fees and service fees varies among the classes offered by the Fund. Because these fees are paid out of the Fund's assets on an ongoing basis, these fees will increase the cost of your investment in the Fund. By purchasing a class of Shares subject to higher distribution fees and service fees, you may pay more over time than on a class of Shares with other types of sales charge arrangements. Long-term

shareholders may pay more than the economic equivalent of the maximum front-end sales charges permitted by the rules of the Financial Industry Regulatory Authority ("FINRA"). The net income attributable to a class of Shares will be reduced by the amount of the distribution fees and service fees and other expenses of the Fund associated with that class of Shares.

To assist investors in comparing classes of Shares, the tables under the Prospectus heading "Fees and Expenses of the Fund" provide a summary of sales charges and expenses and an example of the sales charges and expenses of the Fund applicable to each class of Shares offered herein.

How to Buy Shares

The Class A Shares, Class C Shares and Class Y Shares are offered on a continuous basis through Invesco Distributors as principal underwriter, which is located at 11 Greenway Plaza, Suite 1000, Houston, Texas 77046-1173. Invesco Distributors, Inc. is an indirect wholly owned subsidiary of Invesco Ltd. Shares may be purchased through members of FINRA who are acting as securities dealers ("dealers") and FINRA members or eligible non-FINRA members who are acting as brokers or agents for investors ("brokers"). Dealers and brokers are sometimes referred to herein as authorized dealers.

Shares may be purchased on any business day by completing the account application form and forwarding it, directly or through an authorized dealer, administrator, custodian, trustee, record keeper or financial adviser, to the Fund's shareholder service agent, Invesco Investment Services, Inc. ("Invesco Investment Services"). When purchasing shares of the Fund, investors must specify the correct class of shares by selecting the correct Fund number on the account application form. Sales personnel of authorized dealers distributing the Fund's shares are entitled to receive compensation for selling such Shares and may receive differing compensation for selling different classes of shares.

The Adviser and/or Invesco Distributors may pay compensation (out of their own funds and not as an expense of the Fund) to certain affiliated or unaffiliated authorized dealers in connection with the sale or retention of Fund Shares and/or shareholder servicing. Such compensation may be significant in amount and the prospect of receiving, or the receipt of, such compensation may provide both affiliated and unaffiliated entities, and their representatives or employees, with an incentive to favor sales or retention of Shares of the Fund over other investment options. Any such payments will not change the net asset value or the price of the Fund's Shares. For more information, please see "Sales Compensation" below and/or contact your authorized dealer. The offering price for Shares is based upon the next determined net asset value per Share (plus sales charges, where applicable) after an order is received timely by Invesco Investment Services, either directly or from authorized dealers, administrators, financial advisers, custodians, trustees or record keepers. Purchases completed through an authorized dealer, administrator, custodian, trustee, record keeper or financial adviser may involve additional fees charged by such person. Orders received by Invesco Investment Services prior to the close of the Exchange, and orders received by authorized dealers, administrators, custodians, trustees, record keepers or financial advisers prior to the close of the Exchange that are properly transmitted to Invesco Investment Services by the time designated by Invesco Investment Services, are priced based on the date of receipt. Orders received by Invesco Investment Services after the close of the Exchange, and orders received by authorized dealers, administrators, custodians, trustees, record keepers or financial advisers after the close of the Exchange or orders received by such persons that are not transmitted to Invesco Investment Services until after the time designated by Invesco Investment Services, are priced based on the date of the next determined net asset value per Share provided they are received timely by Invesco Investment Services on such date. It is the responsibility of authorized dealers, administrators, custodians, trustees, record keepers or financial advisers to transmit orders received by them to Invesco Investment Services so they will be received in a timely manner.

The Fund and Invesco Distributors reserve the right to reject or limit any order to purchase Fund Shares through exchange or otherwise and to close any shareholder account when they believe it is in the best interests of the Fund. Certain patterns of past exchanges and/or purchase or sale transactions involving the Fund or other Participating Funds (as defined below) may result in the Fund rejecting or limiting, in the Fund's or Invesco Distributors' discretion, additional purchases and/or exchanges or in an account being closed. Determinations in this regard may be made based on the frequency or dollar amount of the previous exchanges or purchase or sale transactions. The Fund also reserves the right to suspend the sale of the Fund's Shares to investors in response to conditions in the securities markets or for other reasons. As used herein, "Participating Funds" refers to Invesco investment companies advised by the Adviser and distributed by Invesco Distributors as determined from time to time by the Fund's Board of Trustees.

Investor accounts with respect to Class A Shares, Class C Shares and Class Y Shares will automatically be credited with additional Shares of the Fund after any Fund distributions, unless the investor instructs the Fund otherwise. With respect to Class IC Shares and Class IB Shares, previous instructions regarding reinvestment of dividends and distributions will continue to apply until such shareholder changes his or her instruction. Investors wishing to receive cash instead of additional Shares should contact the Fund by visiting our website at www.invesco.com/us, by writing to the Fund, c/o Invesco Investment Services, Inc., P.O. Box 219078, Kansas City, Missouri 64121-9078 or by telephone at (800) 959-4246.

The minimum initial investment in the Fund is $1,000; $250 for tax-sheltered retirement plans (see "Shareholder Services - Retirement plans"). The minimum subsequent investment is $50.

To help the government fight the funding of terrorism and money laundering activities, the Fund has implemented an anti-money laundering compliance program and has designated an anti- money laundering compliance officer. As part of the program, federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. What this means to you: when you open an account, you will be asked to provide your name, address, date of birth, and other information that will allow us to identify you. The Fund and Invesco Distributors reserve the right to not open your account if this information is not provided. If the Fund or Invesco Distributors is unable to verify your identity, the Fund and Invesco Distributors reserve the right to restrict additional transactions and/or reject your attempted purchase of Shares or take any other action required by law.

Class A Shares

Class A Shares of the Fund are sold at the offering price, which is net asset value plus an initial maximum sales charge of up to 3.25% (or 3.36% of the net amount invested). Reductions on investments of $100,000 or more as well as other sales charge waivers and discounts are described below.

The availability of certain sales charge waivers and discounts will depend on how you purchase your shares. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load ("CDSC") waivers, exchanges or conversions between classes or exchanges between Funds; account investment minimums; and minimum account balances, which are discussed below. In all instances, it is the purchaser's responsibility to notify the Fund or the purchaser's financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers, discounts or other special arrangements. For waivers and discounts not available through a particular intermediary, shareholders should consult their financial advisor to consider their options.

† The actual sales charge that may be paid by an investor may differ slightly from the sales charge shown above due to rounding that occurs in the calculation of the offering price and in the number of Shares purchased.

†† No sales charge is payable at the time of purchase on investments in Class A Shares of $1 million or more, although such Class A Shares purchased without a sales charge may be subject to an early withdrawal charge of 1.00% on certain repurchases by the Fund made within eighteen months of purchase. The early withdrawal charge is assessed on an amount equal to the lesser of the then current market value of the Shares or the historical cost of the Shares (which is the amount actually paid for the Shares at the time of original purchase) being repurchased by the Fund. Accordingly, no early withdrawal charge is imposed on increases in net asset value above the initial purchase price. Shareholders should retain any records necessary to substantiate the historical cost of their Shares, as the Fund and authorized dealers may not retain this information.

No sales charge is imposed on Class A Shares received from reinvestment of dividends and distributions.

Under the Distribution Plan and the Service Plan, the Fund may spend up to a total of 0.25% per year of the Fund's average daily net assets with respect to Class A Shares of the Fund. The aggregate distribution fees and service fees paid for the Fund's last fiscal year were 0.25% of the average daily net assets attributable to Class A Shares of the Fund.

Class A Shares

Quantity Discounts

Investors purchasing Class A Shares may, under certain circumstances described below, be entitled to pay reduced or no sales charges. A person eligible for a reduced sales charge includes an individual, his or her spouse or equivalent, children under 21 years of age and any corporation, partnership or sole proprietorship which is 100% owned, either alone or in combination, by any of the foregoing, a trustee or other fiduciary purchasing for a single trust or for a single fiduciary account, or a "company" as defined in Section 2(a)(8) of the 1940 Act.

Investors must notify the Fund or their authorized dealer at the time of the purchase order whenever a quantity discount is applicable to purchases and may be required to provide the Fund, or their authorized dealer, with certain information or records to verify eligibility for a quantity discount. Such information or records may include account statements or other records for shares of the Fund or other Participating Funds in all accounts (e.g., retirement accounts) of the investor and other eligible persons, as described above, which may include accounts held at the Fund or at other authorized dealers.

Upon such notification, an investor will pay the lowest applicable sales charge. Shareholders should retain any records necessary to substantiate the purchase price of the Shares, as the Fund and authorized dealers may not retain this information.

Quantity discounts may be modified or terminated at any time. For more information about quantity discounts, investors should contact the Fund, their authorized dealer or Invesco Distributors.

Volume discounts. The size of investment shown in the Class A Shares sales charge table applies to the total dollar amount being invested by any person in Shares of the Fund, or in any combination of Shares of the Fund and shares of other Participating Funds, although other Participating Funds may have different sales charges.

Cumulative purchase discount. The size of investment shown in the Class A Shares sales charge table may also be determined by combining the amount being invested in shares of the Participating Funds

plus the current offering price of all shares of the Participating Funds currently owned.

Letter of Intent. A Letter of Intent provides an opportunity for an investor to obtain a reduced sales charge by aggregating investments over a 13-month period to determine the sales charge as outlined in the Class A Shares sales charge table. The size of investment shown in the Class A Shares sales charge table includes purchases of shares of the Participating Funds in Class A Shares over a 13-month period based on the total amount of intended purchases, including any applicable credit for the current offering price of all shares of the Participating Funds previously purchased and still owned as of the date of the Letter of Intent. Each investment made during the period receives the reduced sales charge applicable to the total amount of the investment goal. The Letter of Intent does not preclude the Fund (or any other Participating Fund) from discontinuing the sale of its Shares. The initial purchase must be for an amount equal to at least 5% of the minimum total purchase amount of the level selected. The Fund initially will escrow Shares totaling 5% of the dollar amount of the Letter of Intent to be held by Invesco Investment Services in the name of the shareholder. In the event the Letter of Intent goal is not achieved within the specified period, the investor must pay the difference between the sales charge applicable to the purchases made and the reduced sales charge previously paid. Such payments may be made directly to Invesco Distributors or, if not paid, Invesco Distributors will liquidate sufficient escrowed Shares to obtain the difference.

Class A Shares Purchase Programs

Purchasers of Class A Shares may be entitled to reduced or no initial sales charges in connection with certain unit investment trust reinvestment program repurchases and purchases by registered representatives of selling firms or purchases by persons affiliated with the Fund or Invesco Distributors as described below. The Fund reserves the right to modify or terminate these arrangements at any time.

Net asset value purchase options. Class A Shares of the Fund may be purchased at net asset value without a sales charge, generally upon written assurance that the purchase is made for investment purposes and that the Shares will not be resold except through repurchases by the Fund, by:

operational requirements. Trustees and other fiduciaries may call Invesco Distributors for further details with respect to such alliance programs.

The term "families" includes a person's spouse or equivalent, children and grandchildren under 21 years of age, parents and the parents of the person's spouse or equivalent.

Purchase orders made pursuant to clause (3) may be placed either through authorized dealers as described above or directly with Invesco Investment Services by the investment adviser, financial planner, trust company or bank trust department, provided that Invesco Investment Services receives federal funds for the purchase by the close of business on the next business day following acceptance of the order. An authorized dealer may charge a transaction fee for placing an order to purchase Shares pursuant to this provision or for placing an order in a repurchase offer by the Fund with respect to such Shares. Authorized dealers will be paid a service fee as described above on purchases made under options (2) through (8) above. The Fund may terminate, or amend the terms of, offering Shares of the Fund at net asset value to such groups at any time.

Rights of Accumulation. Investors may combine new purchases of Class A Shares with other Shares of the Fund currently owned for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of an investor's current purchase and the value of other Shares of the Fund owned by such investor based on the current public offering price of the Shares. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying an investor for lower initial sales charge rates.

Eligible purchasers of Class A Shares may also be entitled to reduced or no initial sales charges through certain purchase programs offered by the Fund. For more information, see "Other Purchase Programs" herein.

PFS Investments Inc. ("PFSI")

Policies Regarding Transactions Through PFSI

Shareholders purchasing Fund shares through PFSI are eligible only for the following share classes:

Class C Shares

Class C Shares of the Fund are sold at net asset value and are subject to an early withdrawal charge of 1.00% of the dollar amount subject to charge if repurchased by the Fund within one year of purchase.

The early withdrawal charge is assessed on an amount equal to the lesser of the then current market value of the Shares or the historical cost of the Shares (which is the amount actually paid for the Shares at the time of original purchase) being repurchased by the Fund. Accordingly, no early withdrawal charge is imposed on increases in net asset value above the initial purchase price. Shareholders should retain any records necessary to substantiate the historical cost of their Shares, as the Fund and authorized dealers may not retain this information. In addition, no early withdrawal charge is assessed on Shares derived from reinvestment of dividends or distributions. The Fund will not accept a purchase order for Class C Shares in the amount of $1 million or more.

In determining whether an early withdrawal charge applies to a repurchase of Shares, it is assumed that the Shares being repurchased first are any Shares in the shareholder's Fund account that are not subject to an early withdrawal charge, followed by Shares held the longest in the shareholder's account.

Under the Distribution Plan, the Fund may spend up to 0.75% per year of the Fund's average daily net assets with respect to Class C Shares of the Fund. In addition, under the Service Plan, the Fund may spend up to 0.25% per year of the Fund's average daily net assets with respect to Class C Shares of the Fund. Pursuant to the terms of the Plans, the Fund may spend less (and therefore shareholders may be charged less) than the combined annual distribution and service fees of 1.00% per year of the Fund's average daily net assets with respect to Class C Shares of the Fund. See the section entitled "Financial Highlights" herein and the section entitled "Distribution and Service" in the Fund's Statement of Additional Information. The aggregate distribution fees and service fees paid for the Fund's last fiscal year were 1.00% of the average daily net assets attributable to Class C Shares of the Fund.

Eligible purchasers of Class C Shares may also be entitled to reduced or no early withdrawal charges through certain purchase programs offered by the Fund. For more information, see "Other Purchase Programs" herein.

Class Y Shares

Class Y Shares of the Fund are sold at net asset value. No sales charge is imposed on purchases of Class Y Shares. Class Y Shares are not subject to an early withdrawal charge. Class Y Shares do not pay distribution fees or service fees under the Distribution Plan or Service Plan, respectively.

Waiver of Early Withdrawal Charge

The early withdrawal charge is waived on repurchases by the Fund of Class A Shares and Class C Shares purchased subject to an early withdrawal charge pursuant to a repurchase offer (i) within one year following the death or disability (as disability is defined by federal income tax law) of a shareholder, (ii) for required minimum distributions from an individual retirement account ("IRA") or certain other retirement plan distributions or (iii) if no commission or transaction fee is paid by Invesco Distributors to authorized dealers at the time of purchase of such Shares. With respect to Class C Shares, waiver category (iii) above is only applicable with respect to Shares sold through certain 401(k) plans. Subject to certain limitations, a shareholder who has tendered for repurchase Class C Shares of the Fund may reinvest in Class C Shares at net asset value with credit for any early withdrawal charge if the reinvestment is made within 180 days after the repurchase, provided that Shares of the Fund are available for sale at the time of reinvestment. For a more complete description of early withdrawal charge waivers, please refer to the Statement of Additional Information or contact your authorized dealer. The Class Y Shares, Class IB Shares and Class IC Shares have no early withdrawal charges (the early withdrawal schedules applicable to the former Class B Shares and former Class C Shares outstanding on February 18, 2005 have been terminated).

Other Purchase Programs

Exchange privilege. Exchanges of shares are sales of shares of one Participating Fund and purchases of shares of another Participating Fund. Class A Shares, Class C Shares and Class Y Shares of the Fund may be exchanged for shares of the same class of any Participating Fund, and Class IB Shares and Class IC Shares of the Fund may be exchanged for Class A Shares of any Participating Fund (other than the Fund), based on the net asset value per share of each fund determined on the Fund's next repurchase pricing date, after the Fund makes a repurchase pursuant to a repurchase offer, without any sales charge or early withdrawal charge, subject to minimum purchase requirements and certain limitations. For more information regarding the exchange privilege, see the section of this Prospectus entitled "Shareholder Services - Exchange privilege."

Reinstatement privilege. A holder of Class A Shares, Class Y Shares, Class IB Shares or Class IC Shares who has tendered for repurchase Shares of the Fund may reinstate any portion or all of the net proceeds of such repurchase (and may include that amount necessary to acquire a fractional Share to round off his or her purchase to the next full Share) in Class A Shares of any Participating Fund. A holder of Class C Shares who has tendered for repurchase Shares of the Fund may reinstate any portion or all of the net proceeds of such repurchase (and may include that amount necessary to acquire a fractional Share to round off his or her purchase to the next full Share) in Class C Shares of any Participating Fund with credit given for any early withdrawal charge paid on the amount of shares reinstated from such repurchase, provided that such shareholder has not previously exercised this reinstatement privilege with respect to Class C Shares of the Fund. Shares acquired in this manner will be deemed to have the original cost and purchase date of the repurchased Shares for purposes of applying the early withdrawal charge applicable to Class C Shares to subsequent repurchases. Reinstatements are made at the net asset value per Share (without a sales charge) next determined after the order is received, which must be made within 180 days after the date of the repurchase by the Fund of the Shares, provided that Shares of the

Participating Fund into which shareholders desire to reinstate their net proceeds of a repurchase of Shares of the Fund are available for sale. Reinstatement at net asset value per Share is also offered to participants in eligible retirement plans for repayment of principal (and interest) on their borrowings on such plans, provided that Shares of the Participating Fund are available for sale. Shareholders must notify Invesco Distributors or their authorized dealer of their eligibility to participate in the reinstatement privilege and may be required to provide documentation to the Participating Fund. For information regarding Participating Funds, shareholders can call Invesco Investment Services at (800) 959-4246.

Dividend diversification. A holder of Class A Shares, Class C Shares or Class Y Shares may elect, by completing the appropriate section of the account application form or by calling (800) 959-4246, to have all dividends and distributions paid on such class of Shares of the Fund invested into shares of the same class of any of the Participating Funds so long as the investor has a pre-existing account for such class of shares of the other fund. A holder of Class IB or Class IC Shares may elect (or may modify a prior election), by completing the appropriate section of the account application form or by calling (800) 959-4246, to have all dividends and distributions paid on such class of Shares of the Fund invested into Class A Shares of any of the Participating Funds (other than the Fund) so long as the investor has a pre-existing account for such class of shares of the other fund. A holder of Class IB or Class IC Shares who prior to February 18, 2005 elected to utilize dividend diversification with respect to former Class B Shares (now Class IB Shares) or former Class C Shares (now Class IC Shares) of the Fund will have all dividends and distributions paid on such class of Shares of the Fund invested into the class of shares of the Participating Fund previously designated by such shareholder, unless such shareholder changes his or her election (the method of which is described above).

Both accounts must be of the same type, either non-retirement or retirement. If the accounts are retirement accounts, they must both hold the same class of Shares and be of the same type of retirement plan (e.g., IRA, 403(b)(7), 401(k), Money Purchase and Profit Sharing plans) and for the benefit of the same individual. If a qualified, pre-existing account does not exist, the shareholder must establish a new account subject to any requirements of the Participating Fund into which distributions will be invested. Distributions are invested into the selected Participating Fund, provided that shares of such Participating Fund are available for sale, at its net asset value per share as of the payable date of the distribution from the Fund.

Rights of Accumulation. Investors may combine new purchases of Class C Shares with other Shares of the Fund currently owned for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of an investor's current purchase and the value of other Shares of the Fund owned by such investor based on the current public offering price of the Shares. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying an investor for lower initial sales charge rates.

Availability of information. Clear and prominent information regarding sales charges of the Fund and the applicability and availability of discounts from sales charges is available free of charge through our website at www.invesco.com, which provides links to the Prospectus and Statement of Additional Information containing the relevant information.

Sales Compensation

Invesco Distributors acts as the principal underwriter of the Fund's Shares pursuant to a written agreement (the "Distribution and Service Agreement"). Invesco Distributors has the exclusive right to distribute Shares of the Fund through authorized dealers on a continuous basis. Invesco Distributors' obligation is an agency or "best efforts" arrangement under which Invesco Distributors is required to take and pay for only such Shares of the Fund as

may be sold to the public. Invesco Distributors is not obligated to sell any stated number of Shares. Invesco Distributors bears the cost of printing (but not typesetting) prospectuses used in connection with this offering and certain other costs, including the cost of supplemental sales literature and advertising. The Distribution and Service Agreement is renewable from year to year if approved (a) (i) by the Fund's Board of Trustees or (ii) by a vote of a majority of the Fund's outstanding voting securities and (b) by a vote of a majority of trustees who are not parties to the Distribution and Service Agreement or interested persons of any party. The Distribution and Service Agreement provides that it will terminate if assigned and that it may be terminated without penalty by either party on 90 days' written notice. Total underwriting commissions on the sale of Shares of the Fund for the last three fiscal years are shown in the chart below.

	Total Underwriting Commissions	Amounts Retained by the Fund's Distributor
Fiscal year ended February 28, 2022	$30,053	$3,472
Fiscal year ended February 28, 2021	$11,500	$1,928
Fiscal year ended February 29, 2020	$12,842	$1,574

With respect to sales of Class A Shares of the Fund, the total concessions reallowed to authorized dealers at the time of purchase are as follows:

Size of Investment	Reallowed to Dealers as a Percentage of Offering Price
Less than $100,000	3.00%
$100,000 but less than $250,000	2.50%
$250,000 but less than $500,000	1.50%
$500,000 but less than $1,000,000	1.25%
$1,000,000 or more	†

† A commission or transaction fee will be paid by Invesco Distributors at the time of purchase directly out of Invesco Distributors' assets (and not out of the Fund's assets) to authorized dealers who initiate and are responsible for purchases of $1 million or more computed as a percentage of the dollar value of such Shares sold as follows: 1.00% on sales of $1 million to $2 million, plus 0.75% on the next $1 million, plus 0.50% on the next $2 million, plus 0.25% on the excess over $5 million. On sales of less than $1 million, authorized dealers are eligible to receive the ongoing service fees with respect to such Shares immediately following the purchase. On sales greater than $1 million, authorized dealers become eligible to receive the ongoing service fees with respect to such Shares commencing in the second year following purchase; the proceeds from the distribution and service fees paid by the Fund during the first twelve months are paid to the Fund's distributor and are used by the Fund's distributor to defray its distribution and service-related expenses.

With respect to sales of Class C Shares of the Fund, a commission or transaction fee generally will be paid by Invesco Distributors at the time of purchase directly out of Invesco Distributors' assets (and not out of the Fund's assets) to authorized dealers who initiate and are responsible for such purchases computed based on a percentage of the dollar value of such Shares sold of 1.00% on Class C Shares. Proceeds from any early withdrawal charge and any distribution fees on Class C Shares of the Fund are paid to Invesco Distributors and are used by Invesco Distributors to defray its distribution-related expenses in connection with the sale of the Fund's Shares, such as the payment to authorized dealers for selling such Shares. With respect to Class C Shares, the authorized dealers generally receive from Invesco Distributors ongoing distribution fees of up to 0.75% of the average daily net assets of the Fund's Class C Shares annually commencing in the second year after purchase.

With respect to Class C Shares, the authorized dealers are eligible to receive the ongoing service fees with respect to such Shares immediately following the purchase.

With respect to Class Y Shares, Class IB Shares and Class IC Shares, there are no sales charges paid by investors. On February 18, 2005, the Fund redesignated its Class B Shares issued before February 18, 2005 as a new class of Shares designated Class IB Shares and redesignated its Class C Shares issued before February 18, 2005 as a new Class of Shares

designated Class IC Shares. The Class IB Shares and Class IC Shares have no early withdrawal charges (the early withdrawal schedules applicable to the former Class B Shares and former Class C Shares outstanding on February 18, 2005 have been terminated). Class Y Shares and Class IB Shares are not subject to the Distribution Plan or Service Plan and the Class IC Shares are not subject to the Distribution Plan but are subject to the Service Plan. With respect to Class IB Shares and Class IC Shares that were converted from Class B Shares or Class C Shares, respectively, the former authorized dealer compensation arrangements applicable to such Shares before conversion will continue to apply to such Shares whereby Invesco Distributors pays, out of its funds, as follows:

Class IB Shares (former Class B Shares) Year After Date of Original Purchase	Class IB Shares (former Class B Shares) Annual Compensation as a Percentage of Value of Outstanding Shares
First	0.00%
Second	0.10%
Third	0.15%
Fourth	0.20%
Fifth	0.25%
Sixth and following	0.35%

Class IC Shares (former Class C Shares) Year After Date of Original Purchase	Class IC Shares (former Class C Shares) Annual Compensation as a Percentage of Value of Shares Outstanding
First	0.00%
Second and following	0.75%

In addition to reallowances or commissions described above, Invesco Distributors may from time to time implement programs under which an authorized dealer's sales force may be eligible to win nominal awards for certain sales efforts or under which Invesco Distributors will reallow to any authorized dealer that sponsors sales contests or recognition programs conforming to criteria established by Invesco Distributors, or participates in sales programs sponsored by Invesco Distributors, an amount not exceeding the total applicable sales charges on the sales generated by the authorized dealer at the public offering price during such programs. Also, Invesco Distributors in its discretion may from time to time, pursuant to objective criteria established by Invesco Distributors, pay fees to, and sponsor business seminars for, qualifying authorized dealers for certain services or activities which are primarily intended to result in sales of shares of the Fund or other Invesco funds. Fees may include payment for travel expenses, including lodging, incurred in connection with trips taken by invited registered representatives for meetings or seminars of a business nature.

The Adviser and/or Invesco Distributors may pay compensation, out of their own funds and not as an expense of the Fund, to certain unaffiliated brokers, dealers or other financial intermediaries, including recordkeepers and administrators of various deferred compensation plans ("Intermediaries") in connection with the sale, distribution, marketing and/or retention of the Fund's Shares and/or shareholder servicing. For example, the Adviser or Invesco Distributors may pay additional compensation to Intermediaries for, among others things, promoting the sale and distribution of the Fund's Shares, providing access to various programs, mutual fund platforms or preferred or recommended mutual fund lists offered by the Intermediary, granting Invesco Distributors access to the Intermediary's financial advisors and consultants, providing assistance in the ongoing training and education of the Intermediary's financial personnel, furnishing marketing support, maintaining share balances and/or for sub-accounting, recordkeeping, administrative, shareholder or transaction processing services. Such payments are in addition to any distribution fees, service fees and/or transfer agency fees that may be payable by the Fund. The additional payments may be based on various factors, including level of sales (based

on gross or net sales or some specified minimum sales or some other similar criteria related to sales of the Fund and/or some or all other Invesco funds), amount of assets invested by the Intermediary's customers (which could include current or aged assets of the Fund and/or some or all other Invesco funds), the Fund's advisory fees, some other agreed upon amount, or other measures as determined from time to time by the Adviser and/or Invesco Distributors. The amount of these payments may be different for different Intermediaries.

These payments currently include the following amounts, which are paid in accordance with the applicable compensation structure: (1) on shares held in Intermediary accounts, other than those held through Intermediary 401(k) platforms: (a) an amount up to 0.25% of the value (at the time of sale) of gross sales of such Shares; and/or (b) an ongoing annual fee in an amount up to 0.15% of the total average monthly net asset value of such Shares; and (2) on shares held in accounts through certain Intermediary 401(k) platforms, an ongoing annual fee in an amount up to 0.20% of the total average monthly net asset value of such Shares.

The prospect of receiving, or the receipt of, such compensation, as described above, by Intermediaries may provide Intermediaries, and/or their financial advisors or other salespersons, with an incentive to favor sales of Shares of the Fund over other investment options with respect to which an Intermediary does not receive additional compensation (or receives lower levels of additional compensation). These payment arrangements, however, will not change the price that an investor pays for Shares of the Fund or the amount that the Fund receives to invest on behalf of an investor. Investors may wish to take such payment arrangements into account when considering and evaluating any recommendations relating to the Fund's Shares and should review carefully any disclosure provided by an Intermediary as to its compensation.

Indemnification

The Fund has agreed to indemnify Invesco Distributors and hold Invesco Distributors harmless against, or contribute to losses arising out of, certain liabilities, including liabilities under the Securities Act of 1933, as amended, except for any liability to the Fund or its security holders to which Invesco Distributors would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties, or by its reckless disregard of its obligations and duties under its agreement with the Fund.

Repurchase of Shares

To provide you with a degree of liquidity, and the ability to receive net asset value on a disposition of your Shares, the Fund, as a matter of fundamental policy, which cannot be changed without shareholder approval, makes monthly offers to repurchase its Shares. In general, the Fund conducts monthly repurchase offers for not less than 5% and up to a maximum of 25% of its outstanding Shares at net asset value. The repurchase offer amount for any monthly period, plus the repurchase offer amounts for the two monthly periods immediately preceding such monthly period, will not exceed 25% of the Fund's outstanding Shares. The Fund may repurchase additional Shares only to the extent the percentage of additional Shares so repurchased does not exceed 2% in any three-month period. The Fund may also make a discretionary repurchase offer once every two years but has no current intention to do so. An early withdrawal charge payable to Invesco Distributors will be imposed on most Class C Shares accepted for repurchase by the Fund which have been held for less than five years or one year, respectively (and in certain circumstances on Class A Shares accepted for repurchase by the Fund which have been held for less than eighteen months), as described more fully under "Purchase of Shares." There are no early withdrawal charges on Class Y Shares, Class IB Shares or Class IC Shares.

The Fund does not presently intend to deduct any repurchase fees, other than any applicable early withdrawal charge, from the repurchase amount. However, in the future, the Board of Trustees may determine to charge a repurchase fee payable to the Fund to compensate it for its reasonable expenses directly related to the repurchase. These fees could be used to compensate the Fund for, among other things, its costs incurred in disposing of portfolio securities or in borrowing in order to make payment for repurchased Shares. Any repurchase fees will never exceed 2% of the proceeds of the repurchase. The Board of Trustees may implement repurchase fees without a shareholder vote.

The repurchase request deadline for monthly repurchase offers will be the third Friday (or the preceding business day if such third Friday is not a business day) of each calendar month. When a monthly repurchase offer commences, the Fund sends to shareholders a notification of the offer specifying, among other things:

For monthly repurchase offers, the Fund will send this notification not less than seven days nor more than 14 days in advance of the repurchase request deadline. Class A Shares, Class C Shares and Class Y Shares of the Fund must be held through an authorized dealer. Certificated Shares are not available.

The repurchase request deadline is a deadline that will be strictly observed. If your authorized dealer fails to submit your repurchase request in good order by the repurchase request deadline, you will be unable to liquidate your Shares until a subsequent repurchase offer, and you will have to resubmit your request in the next repurchase offer. You should be sure to advise your authorized dealer of your intentions in a timely

manner. You may withdraw or change your repurchase request at any point before the repurchase request deadline.

The Fund's fundamental policies with respect to repurchase offers. The Fund has adopted the following fundamental policies in relation to its repurchase offers, which cannot be changed without the approval of the holders of a majority (defined as the lesser of (i) 67% or more of the voting securities present at a meeting of shareholders, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy at such meeting, or (ii) more than 50% of the outstanding voting securities) of the Fund's outstanding Shares.

The Fund has a policy of making periodic repurchase offers ("Repurchase Offers") for the Fund's common shares of beneficial interest, pursuant to Rule 23c-3(b) of the 1940 Act;

Repurchase Offers will be made at monthly intervals;

The repurchase request deadline will be the third Friday of each calendar month (or the preceding business day if such third Friday is not a business day) (the "Request Deadline").

The repurchase pricing date for a Repurchase Offer shall occur no later than the fourteenth calendar day after such Repurchase Offer's Request Deadline (or the next business day after such fourteenth calendar day if the fourteenth calendar day is not a business day).

Suspension or postponement of repurchase offer. The Fund may suspend or postpone a repurchase offer in limited circumstances, as more fully described below, but only with the approval of a majority of the Fund's Board of Trustees, including a majority of non-interested trustees (such trustees not being "interested persons" of the Fund as defined by the 1940 Act).

The Fund may suspend or postpone a repurchase offer only: (1) if making or effecting the repurchase offer would cause the Fund to lose its status as a regulated investment company under the Code; (2) for any period during which the Exchange or any market in which the securities owned by the Fund are principally traded is closed, other than customary weekend and holiday closings, or during which trading in such market is restricted; (3) for any period during which an emergency exists as a result of which disposal by the Fund of securities owned by it is not reasonably practicable, or during which it is not reasonably practicable for the Fund fairly to determine the value of its net assets; or (4) for such other periods as the SEC may by order permit for the protection of shareholders of the Fund.

Oversubscribed repurchase offers. There is no minimum number of Shares that must be tendered before the Fund honors repurchase requests. However, the Fund's Board of Trustees for each repurchase offer sets a maximum percentage of Shares that may be purchased by the Fund. In the event a repurchase offer by the Fund is oversubscribed, the Fund may, but is not required to, repurchase additional Shares up to a maximum amount of 2% of the outstanding Shares of the Fund on the repurchase request deadline. If the Fund determines not to repurchase additional Shares beyond the repurchase offer amount, or if shareholders tender an amount of Shares greater than that which the Fund is entitled to purchase plus 2% of the outstanding Shares of the Fund on the repurchase request deadline, the Fund repurchases the Shares tendered on a pro rata basis. However, the Fund may determine to alter the pro rata allocation procedures in two situations:

If proration is necessary, the number of Shares each investor asked to have repurchased generally is reduced by the same percentage subject to the pro rata allocations described above. If any Shares that you wish to tender to the Fund are not repurchased because of proration, you will have to wait until the next repurchase offer and resubmit your repurchase request, and your repurchase request will not be given any priority over other investors' requests. Thus, there is a risk that the Fund may not purchase all of the Shares you wish to have repurchased in a given repurchase offer or in any subsequent repurchase offer. In anticipation of the possibility of proration, some shareholders may tender more Shares than they wish to have repurchased in a particular repurchase offer, thereby increasing the likelihood of proration.

There is no assurance that you will be able to tender as many of your Shares as you desire to sell.

Determination of repurchase price. The repurchase price payable in respect of a tendered Share will be equal to the Share's net asset value as determined after the close of business on the repurchase pricing date. Under normal circumstances, the Fund expects that the repurchase pricing date will be the repurchase request deadline. The Fund's net asset value per Share may change materially between the date a repurchase offer is mailed and the repurchase pricing date. The method by which the Fund calculates net asset value is discussed under the caption "Net Asset Value" in the Statement of Additional Information.

Payment. The Fund generally will repurchase Shares by the third business day after the repurchase pricing date, although payment for shares may be as many as seven days after the repurchase request deadline; in any event, the Fund will pay such proceeds at least five business days before notification of the next repurchase offer.

Impact of repurchase policies on the liquidity of the Fund.From the time the Fund distributes each repurchase offer notification until the repurchase pricing date, the Fund must maintain a percentage of liquid assets at least equal to the repurchase offer amount. For this purpose, liquid assets means assets that may be sold or disposed of in the ordinary course of business at approximately the price at which they are valued within a period equal to the period between a repurchase request deadline and the repurchase payment deadline or which mature by the repurchase payment deadline. In supervising the Fund's operations and portfolio management by the Adviser, the Fund's Board of Trustees has adopted written procedures that are reasonably designed to ensure that the Fund's portfolio assets are sufficiently liquid so that the Fund can comply with its fundamental policy on repurchases and with the liquidity requirements noted above. The Board of Trustees will review the overall composition of the Fund's portfolio and make and approve such changes to the procedures as the Board of Trustees deems necessary. If, at any time, the Fund falls out of compliance with these liquidity requirements, the Board of Trustees will cause the Fund to take whatever action it deems appropriate to ensure compliance. The Fund is also permitted to seek financing to meet repurchase requests.

Consequences of repurchase offers. The Fund believes that repurchase offers generally will be beneficial to the Fund's shareholders, and generally will be funded from available cash or sales of portfolio securities. However, the acquisition of Shares by the Fund will decrease the assets of the Fund and, therefore, may have the effect of increasing the Fund's expense ratio. In addition, if the Fund borrows to finance repurchases, interest on that borrowing will negatively affect shareholders who do not tender their Shares by increasing the Fund's expenses and reducing any net investment income. The Fund intends to continually offer its Class A Shares, Class C Shares and Class Y Shares, which may alleviate potential adverse consequences of repurchase offers, but there is no assurance that the Fund will be able to sell additional Shares.

Repurchase of the Fund's Shares through repurchase offers will reduce the number of outstanding Shares and, depending upon the Fund's investment performance and its ability to sell additional Shares, its net assets.

In addition, the repurchase of Shares by the Fund will be a taxable event to shareholders. For a discussion of these tax consequences, see "Federal Income Taxation."

Costs associated with the repurchase offer will be charged as an expense to the Fund. See the Statement of Additional Information for additional information concerning repurchase of Shares.

Early Withdrawal Charges. As described under the Prospectus heading "Purchase of Shares," repurchases of Class C Shares may be subject to an early withdrawal charge. In addition, certain repurchases of Class A Shares for shareholder accounts of $1 million or more may be subject to an early withdrawal charge. Class Y Shares, Class IB Shares and Class IC Shares have no early withdrawal charges.

Shares acquired in connection with the reorganization of the Invesco Prime Income Trust into the Invesco Senior Loan Fund on September 26, 2011 will remain subject to the same early withdrawal schedule. Shareholders will receive credit for the length of time that they held shares of the Invesco Prime Income Fund in the calculation of such early withdrawal charge. An early withdrawal charge is imposed on repurchases of Class IB shares of the Invesco Senior Loan Fund received in connection with the Reorganization at the following rates:

Year After Purchase	Early Withdrawal Charge
Year 1	3.00%
Year 2	2.50%
Year 3	2.00%
Year 4	1.00%
Year 5 and thereafter	None

Repurchases completed through an authorized dealer, custodian, trustee or record keeper of a retirement plan account may involve additional fees charged by such person.

The early withdrawal charge will be paid to Invesco Distributors. For the fiscal years ended February 29, 2020, February 28, 2021 and February 28, 2022 the Fund's distributor received payments totaling $745, $29 and 357 respectively, pursuant to the early withdrawal charge. In determining whether an early withdrawal charge is payable, it is assumed that the acceptance of a repurchase offer would be made from the earliest purchase of Shares.

Distributions from the Fund

Dividends. Interest from investments is the Fund's main source of net investment income. The Fund's present policy, which may be changed at any time by the Fund's Board of Trustees, is to declare daily and distribute monthly all, or substantially all, of its net investment income as dividends to shareholders. Dividends with respect to Class A Shares, Class C Shares and Class Y Shares are automatically applied to purchase additional Shares of the Fund at the next determined net asset value unless the shareholder instructs otherwise. With respect to Class IB Shares and Class IC Shares, previous instructions regarding reinvestment of dividends will continue to apply until such shareholder changes his or her instruction.

The per Share dividends may differ by class of shares as a result of the differing distribution fees, service fees and transfer agency costs applicable to such classes of Shares.

Capital gain distributions. The Fund may realize capital gains or losses when it sells securities, depending on whether the sales prices for the securities are higher or lower than purchase prices. The Fund distributes any net capital gains to shareholders as capital gain distributions at least annually. As in the case of dividends, with respect to Class A Shares, Class C Shares and Class Y Shares, capital gain distributions are automatically reinvested in additional Shares of the Fund at the next determined net asset value unless the shareholder instructs otherwise. With respect to Class IB Shares and Class IC Shares, previous instructions regarding reinvestment of

capital gain distributions will continue to apply until such shareholder changes his or her instruction.

Shareholder Services

Listed below are some of the shareholder services the Fund offers to investors. For a more complete description of the Fund's shareholder services, such as the reinvestment plan, retirement plans and dividend diversification, please refer to the Statement of Additional Information or contact your authorized dealer.

Unless otherwise provided, the following are certain defined terms used throughout this prospectus:

Internet transactions. In addition to performing transactions on your account through written instruction or by telephone, you may also perform certain transactions through the internet (restrictions apply to certain account and transaction types). Please refer to our website at www.invesco.com/us for further instructions regarding internet transactions. Invesco and its subsidiaries, including Invesco Investment Services, and the Fund employ procedures considered by them to be reasonable to confirm that instructions communicated through the internet are genuine. Such procedures include requiring use of a personal identification number prior to acting upon internet instructions and providing written confirmation of instructions communicated through the internet. If reasonable procedures are employed, none of Invesco, Invesco Investment Services or the Fund will be liable for following instructions received through the internet which it reasonably believes to be genuine. If an account has multiple owners, Invesco Investment Services may rely on the instructions of any one owner.

Reinvestment plan. A convenient way for investors to accumulate additional Shares is by accepting dividends and distributions in Shares of the Fund. Such Shares are acquired at net asset value per Share (without a sales charge) on the applicable payable date of the dividend or distribution. Unless the shareholder instructs otherwise, with respect to Class A Shares, Class C Shares and Class Y Shares, the reinvestment plan is automatic. This instruction may be made by visiting our website at www.invesco.com/us, by writing to Invesco Investment Services or by telephone by calling (800) 959-4246. With respect to Class IB Shares and Class IC Shares, previous instructions regarding reinvestment of dividends and distributions will continue to apply until such shareholder changes his or her instruction. The investor may, on the account application form or prior to any declaration, instruct that dividends and/or distributions be paid in cash, be reinvested in the Fund at the next determined net asset value or be reinvested in another Participating Fund at the next determined net asset value. See "Shareholder Services - Reinvestment Plan" in the Fund's Statement of Additional Information for additional information.

Automatic investment plan. An automatic investment plan is available under which a shareholder can authorize Invesco Investment Services to debit the shareholder's bank account on a regular basis to invest predetermined amounts in Class A Shares, Class C Shares and Class Y Shares of the Fund. The automatic investment plan is not available for new investments in Class IB Shares and Class IC Shares. Additional information is available from Invesco Distributors or your authorized dealer.

Exchange privilege. Tendering shareholders may elect to receive, in lieu of cash, the proceeds from the tender and repurchase of Class A Shares, Class C Shares and Class Y Shares of the Fund in the same class of shares of any Participating Fund, subject to certain limitations. Tendering shareholders may elect to receive, in lieu of cash, the proceeds from the tender and repurchase of Class IB Shares and Class IC Shares of the Fund in Class A Shares of any Participating Fund (other than the Fund), subject to certain limitations. The exchange takes place without any sales charge or early withdrawal charge, at the net asset value per share of each fund determined on the Fund's next repurchase pricing date, after the Fund makes a repurchase pursuant to a repurchase offer. The early withdrawal charge will be waived for Shares tendered in exchange for shares in the Participating Funds; however, such shares immediately become subject to a contingent deferred sales charge schedule equivalent to the early withdrawal charge schedule on Shares of the Fund. Thus, shares of such Participating Funds may be subject to a contingent deferred sales charge upon a subsequent redemption from the Participating Funds. The purchase of shares of such Participating Funds will be deemed to have occurred at the time of the initial purchase of the Shares of the Fund for calculating the applicable contingent deferred sales charge.

Shares of Participating Funds generally may be exchanged for Shares of the same class of the Fund (except that some holders of Class I Shares of certain Participating Funds may be eligible to exchange Class I Shares of such Participating Fund for Class A Shares of the Fund) based on the next determined net asset value per share of each fund after requesting the exchange without any sales charge, subject to minimum purchase requirements and certain limitations. Shareholders of Participating Funds seeking to exchange their shares for Shares of the Fund are subject to the exchange policies of such Participating Fund, including an exchange fee, if any, assessed by such Participating Fund.

Shareholders seeking an exchange amongst Participating Funds should obtain and read the current prospectus for such fund prior to implementing an exchange. A prospectus of any of the Participating Funds may be obtained from an authorized dealer or Invesco Distributors or by visiting our website at www.invesco.com/us.

Investors should note exchanges out of the Fund can only occur in connection with a repurchase offer which occurs monthly. See "Repurchase of Shares." Exchanges can occur into the Fund on any day the Fund is offering its Shares, which is generally every business day. Shares of the Fund may be exchanged for shares of any Participating Fund only if shares of that Participating Fund are available for sale. Exchanging shares of other Participating Funds for Shares of the Fund involves certain risks, including the risk that the Fund's Shares are illiquid. See "Principal Risks of Investing in the Fund" generally and "Principal Risks of Investing in the Fund - No Trading Market for Shares."

When shares that are subject to a contingent deferred sales charge or early withdrawal charge are exchanged among Participating Funds, the holding period for purposes of computing the contingent deferred sales charge or early withdrawal charge is based upon the date of the initial purchase of such shares from a Participating Fund. When such shares are redeemed or tendered for repurchase and not exchanged for shares of another Participating Fund, the shares are subject to the contingent deferred sales charge or early withdrawal charge schedule imposed by the Participating Fund from which such shares were originally purchased.

Exchanges of Shares are sales of shares of one Participating Fund and purchases of shares of another Participating Fund. The sale may result in a

gain or loss for federal income tax purposes. If the shares sold have been held for less than 91 days, the sales charge paid on such shares will be carried over and included in the tax basis of the shares acquired.

A shareholder wishing to make an exchange into the Fund from another Participating Fund may do so by sending a written request to Invesco Investment Services, by calling (800) 959-4246, or by visiting our website at www.invesco.com/us. A shareholder automatically has these exchange privileges unless the shareholder indicates otherwise by checking the applicable box on the account application form. A shareholder wishing to make an exchange out of the Fund into another Participating Fund may do so by properly completing the repurchase offer materials at the time of the Fund's next repurchase offer. In the case of telephone transactions, Invesco and its subsidiaries, including Invesco Investment Services, and the Fund employ procedures considered by them to be reasonable to confirm that instructions communicated by telephone are genuine. Such procedures include requiring certain personal identification information prior to acting upon telephone instructions, tape-recording telephone communications, and providing written confirmation of instructions communicated by telephone. If reasonable procedures are employed, none of Invesco, Invesco Investment Services or the Fund will be liable for following telephone instructions which it reasonably believes to be genuine. If the exchanging shareholder does not have an account in the fund whose shares are being acquired, a new account will be established with the same registration, dividend and distribution options (except dividend diversification) and authorized dealer of record as the account from which shares are exchanged, unless otherwise specified by the shareholder. In order to reinvest dividends from the new account into another fund (if such service is available), an exchanging shareholder must submit a specific request.

The Fund and Invesco Distributors reserve the right to reject or limit any order to purchase Fund Shares through exchange or otherwise and to close any shareholder account when they believe it is in the best interests of the Fund. Certain patterns of past exchanges and/or purchase or sale transactions involving the Fund or other Participating Funds may result in the Fund rejecting or limiting, in the Fund's or Invesco Distributors' discretion, additional purchases and/or exchanges. Determinations in this regard may be made based on the frequency or dollar amount of the previous exchanges or purchase or sale transactions. The Fund may modify, restrict or terminate the exchange privilege at any time. Shareholders will receive 60 days' notice of any termination or material amendment to this exchange privilege.

For purposes of determining the sales charge rate previously paid on Class A Shares, all sales charges paid on the exchanged shares and on any shares previously exchanged for such shares or for any of their predecessors shall be included. If the exchanged shares were acquired through reinvestment, those shares are deemed to have been sold with a sales charge rate equal to the rate previously paid on the shares on which the dividend or distribution was paid. If a shareholder exchanges less than all of such shareholder's shares, the shares upon which the highest sales charge rate was previously paid are deemed exchanged first.

Exchange requests into the Fund from other Participating Funds received on a business day prior to the time shares of the funds involved in the request are priced will be processed on the date of receipt. Exchange requests out of the Fund into other Participating Funds are processed after the Fund makes a repurchase pursuant to a repurchase offer. "Processing" a request means that shares of the fund which the shareholder is tendering for repurchase or redeeming will be repurchased or redeemed at the net asset value per share determined on the Fund's next repurchase pricing date in the following repurchase offer, in the case of exchanges out of the Fund, or on the date of receipt, in the case of exchanges out of other Participating Funds. Shares of the fund that the shareholder is purchasing will also normally be purchased at the net asset value per share, plus any applicable sales charge, next determined on the date of receipt. Exchange requests received on a business day after the time that shares of the funds

involved in the request are priced will be processed on the next business day, in the case of exchanges into the Fund, or after the Fund makes a repurchase pursuant to a repurchase offer, in the case of exchanges out of the Fund, in the manner described herein.

As described under "Purchase of Shares - Class A Shares," there is no sales charge payable on Class A Shares at the time of purchase on investments of $1 million or more, but an early withdrawal charge ("EWC-Class A") may be imposed on certain repurchases made within eighteen months of purchase. For purposes of the EWC-Class A and the contingent deferred sales charge on certain redemptions of Class A Shares of other Participating Funds ("CDSC-Class A"), when shares of a Participating Fund are exchanged for shares of another Participating Fund, the purchase date for the shares acquired by exchange will be assumed to be the date on which shares were purchased in the fund from which the exchange was made. If the exchanged shares themselves are acquired through an exchange, the purchase date is assumed to carry over from the date of the original election to purchase shares subject to a CDSC- Class A or EWC-Class A rather than a front-end load sales charge. In determining whether a CDSC- Class A or EWC-Class A is payable, it is assumed that shares being redeemed or repurchased first are any shares in the shareholder's account not subject to a CDSC-Class A or EWC-Class A, followed by shares held the longest in the shareholder's account. The CDSC-Class A or EWC-Class A is assessed on an amount equal to the lesser of the then current market value or the cost of the shares being redeemed or repurchased. Accordingly, no CDSC-Class A or EWC-Class A is imposed on increases in net asset value above the initial purchase price. In addition, no CDSC-Class A or EWC-Class A is assessed on shares derived from reinvestment of dividends or distributions.

Retirement plans. Eligible investors may establish IRAs; SEPs; 401(k) plans; 403(b)(7) plans in the case of employees of public school systems and certain non-profit organizations; or other pension or profit sharing plans. Documents and forms containing detailed information regarding these plans are available from Invesco Distributors.

The illiquid nature of the Shares may affect the nature of distributions from tax-sheltered retirement plans and may affect the ability of participants in such plans to rollover assets to other tax-sheltered retirement plans.

Description of Shares

The Fund was organized as a Massachusetts business trust on July 14, 1989 and was redomesticated as a Delaware statutory trust on October 15, 2012, and is governed by a Declaration of Trust (as amended to the date hereof, the "Declaration of Trust").

The Declaration of Trust permits the Fund to issue an unlimited number of full and fractional common shares of beneficial interest. The Declaration of Trust provides that the trustees of the Fund may authorize separate classes of Shares. Each Share represents an equal proportionate interest in the assets of the Fund with each other Share in the Fund.

The Declaration of Trust provides that no shareholder of the Fund shall be personally liable for the debts, liabilities, obligations and expenses incurred by, contracted for, or otherwise existing with respect to, the Fund or any class of Shares. Neither the Fund nor the Trustees, nor any officer, employee, or agent of the Fund shall have any power to bind personally any shareholder or to call upon any shareholder for the payment of any sum of money or assessment whatsoever other than such as the shareholder may at any time personally agree to pay by way of subscription for any Shares or otherwise. The shareholders shall be entitled, to the fullest extent permitted by applicable law, to the same limitation of personal liability as is extended under the Delaware General Corporation Law to stockholders of private corporations for profit.

The Fund currently continuously offers three classes of Shares, designated as Class A Shares, Class C Shares and Class Y Shares. The Fund also has Class IB Shares and Class IC Shares, which are not continuously

offered. The only new Class IB Shares and Class IC Shares to be issued are those Class IB Shares and Class IC Shares issued to satisfy dividend and capital gain reinvestments. Other classes may be established from time to time in accordance with the provisions of the Declaration of Trust. Each class of Shares of the Fund generally is identical in all respects except that each class of Shares may be subject to its own sales charge or early withdrawal charge schedule and its own distribution and service expenses. Each class of Shares also has exclusive voting rights with respect to its distribution and service fees, if any.

The Declaration of Trust provides that the Board shall have full power and authority, in its sole discretion and without obtaining any prior authorization or vote of the shareholders, to fix or change such preferences, voting powers, rights, and privileges of any class of Shares of the Fund as the Board may from time to time determine; provided, however, that shareholders shall have the power to vote to approve any amendment to the shareholder indemnification provision that would have the effect of reducing the indemnification provided thereby.

Shareholders will be entitled to the payment of dividends and other distributions when, as and if declared by the Board of Trustees. The Declaration of Trust also authorizes the Fund to borrow money and in this connection issue notes or other evidence of indebtedness. The terms of any borrowings may limit the payment of dividends to shareholders.

The Fund does not intend to hold annual meetings of shareholders. At meetings, Shares of the Fund entitle their holders to one vote per Share; however, separate votes are taken by each class of Shares on matters affecting an individual class of Shares.

In the event of liquidation of the Fund, the Fund will pay or make reasonable provision to pay all claims and obligations of the Fund, including all contingent, conditional or unmatured claims and obligations known to the Fund, and all claims and obligations which are known to the Fund, but for which the identity of the claimant is unknown, and claims and obligations that have not been made known to the Fund or that have not arisen but that, based on the facts known to the Fund, are likely to arise or to become known to the Fund within 10 years after the date of dissolution of the Fund. Any remaining assets held with respect to the Fund shall be distributed to the shareholders.

Pursuant to the Fund's Bylaws, all Shares issued by the Fund shall be uncertificated, and no shareholder shall have the right to demand or require that a certificate be issued. The Shares are not, and are not expected to be, listed for trading on any national securities exchange nor, to the Fund's knowledge, is there, or is there expected to be, any secondary trading market in the Shares. Shares of the Fund issued before June 13, 2003 were redesignated as Class B Shares. Class C Shares of the Fund were not issued prior to June 13, 2003. On February 18, 2005, the Fund redesignated its Class B Shares issued before February 18, 2005 as a new class of Shares designated Class IB Shares and redesignated its Class C Shares issued before February 18, 2005 as a new Class of Shares designated Class IC Shares. On February 18, 2005, the Fund commenced offering new Class A Shares, new Class B Shares and new Class C Shares (the new Class B Shares and new Class C Shares have different fees, expenses and other characteristics than the Class B Shares and Class C Shares issued prior to February 18, 2005, which Shares are now redesignated as Class IB Shares and Class IC Shares, respectively). Effective November 30, 2010, Class B Shares of the Fund are not continuously offered. On November 8, 2013, the Fund commenced offering Class Y Shares. On January 26, 2018, Class B shares of the Fund converted to Class A shares.

The following table sets forth, for the quarterly periods ending on the dates set forth below, the high and low net asset value per Share for each class of Shares during such period:

Anti-Takeover Provisions in the Declaration of Trust

The Fund's Declaration of Trust includes provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund or to change the composition of its Board of Trustees by discouraging a third party from seeking to obtain control of the Fund. In addition, in the event a secondary market were to develop in the Shares, such provisions could have the effect of depriving shareholders of an opportunity to sell their Shares at a premium over prevailing market prices.

A trustee may be removed from office at any time, with or without cause, by written instrument signed by at least two-thirds of the number of Trustees prior to such removal, specifying the date when such removal shall become effective.

The Trustees may cause the Fund, to the extent consistent with applicable law, to merge or consolidate with any other entity or to sell all or substantially all of the Fund's assets upon such terms and conditions and for such consideration when and as authorized the Board of Trustees.

The Fund may be dissolved and any class of Shares may be terminated at any time by the Board of Trustees (without shareholder approval).

The Fund may be converted from a "closed-end company" to an "open-end company" upon approval by the Board of Trustees followed by the approval of shareholders as required by the 1940 Act.

The above described provisions in the Declaration of Trust regarding dissolution, conversion and mergers, consolidations and sales of assets cannot be amended without the approval by the Board of Trustees; and no vote or consent of any shareholder shall be required for any amendment to

these provisions except as determined by the Board in its sole discretion or as required by federal law, including the 1940 Act.

Reference should be made to the Declaration of Trust on file with the SEC for the full text of these provisions.

Federal Income Taxation

The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Code. If the Fund so qualifies and distributes each year to its shareholders at least 90% of its investment company taxable income (generally including ordinary income and net short-term capital gain, but not net capital gain, which is the excess of net long-term capital gain over net short-term capital loss) and meets certain other requirements, it will not be required to pay federal income taxes on any income distributed to shareholders. The Fund will not be subject to federal income tax on any net capital gain distributed to shareholders. If the Fund distributes less than an amount equal to the sum of 98% of its ordinary income and 98.2% of its capital gain net income, plus any amounts that were not distributed in previous taxable years, then the Fund will be subject to a nondeductible 4% excise tax on the undistributed amounts.

If the Fund failed to qualify as a regulated investment company in any taxable year, it would be taxed as an ordinary corporation on its taxable income (even if such income were distributed to its shareholders) and all distributions out of earnings and profits would generally be taxed to certain noncorporate U.S. shareholders (including individuals) as "qualified dividend income" eligible for reduced maximum tax rates.

Distributions of the Fund's investment company taxable income are taxable to shareholders as ordinary income to the extent of the Fund's earnings and profits, whether paid in cash or reinvested in additional Shares. Distributions of the Fund's net capital gain designated as capital gain dividends, if any, are taxable to shareholders as long-term capital gains regardless of the length of time Shares have been held by such shareholders, whether paid in cash or reinvested in additional Shares. The Fund expects that its distributions will consist primarily of ordinary income. Distributions in excess of the Fund's earnings and profits will first reduce the adjusted tax basis of a shareholder's Shares and, after such adjusted tax basis is reduced to zero, will constitute capital gain to such shareholder (assuming such Shares are held as a capital asset).

Although distributions generally are treated as taxable in the year they are paid, distributions declared in October, November or December, payable to shareholders of record on a specified date in such month and paid during January of the following year will be treated as having been distributed by the Fund and received by shareholders on the December 31st prior to the date of payment. The Fund will inform shareholders of the source and tax status of all distributions promptly after the close of each calendar year. Because the Fund intends to invest primarily in Senior Loans and other senior debt securities, Fund distributions generally will not qualify for the corporate dividends-received deduction.

Current law provides for reduced federal income tax rates on (i) long-term capital gains received by individuals and certain other non-corporate taxpayers and (ii) "qualified dividend income" received by individuals and certain other non-corporate taxpayers from certain domestic and foreign corporations. Fund shareholders, as well as the Fund itself, must also satisfy certain holding period and other requirements in order for such reduced rates for "qualified dividend income" to apply. Because the Fund intends to invest primarily in Senior Loans and other senior debt securities, ordinary income dividends paid by the Fund generally will not be eligible for the reduced rates applicable to "qualified dividend income." To the extent that distributions from the Fund are designated as capital gain dividends, such distributions will be eligible for the reduced rates applicable to long-term capital gains.

The use of derivatives by the Fund may cause the Fund to realize higher amounts of ordinary income or short-term capital gain, distributions from

which are taxable to individual shareholders at ordinary income tax rates rather than at the more favorable tax rates for long-term capital gain.

Foreign shareholders, including shareholders who are non-resident aliens, may be subject to U.S. withholding tax on certain distributions (whether received in cash or in shares) at a rate of 30% or such lower rate as prescribed by an applicable treaty.

Foreign shareholders must provide documentation to the Fund certifying their non-United States status. Prospective foreign investors should consult their advisers concerning the tax consequences to them of an investment in Shares of the Fund.

The sale or exchange of Shares in connection with a repurchase of Shares, as well as certain other transfers, will be a taxable transaction for federal income tax purposes. Except as discussed below, selling shareholders will generally recognize gain or loss in an amount equal to the difference between their adjusted tax basis in the Shares sold and the amount received. If the Shares are held as a capital asset, the gain or loss will be a capital gain or loss.

Any loss recognized upon a taxable disposition of Shares held for six months or less will be treated as a long-term capital loss to the extent of any capital gain dividends received with respect to such Shares. For purposes of determining whether Shares have been held for six months or less, the holding period is suspended for any periods during which the shareholder's risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property or through certain options or short sales.

Fund distributions and gains from sale or exchange of Fund Shares generally are subject to state and local income taxes.

Any long-term or short-term capital gains realized on sale or redemption of your 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 the Fund is made using the proceeds from a redemption of shares of another Fund and is effectuated on the same day as the redemption. Your gain or loss is calculated by subtracting from the gross proceeds your cost basis. Gross proceeds and, for Shares acquired on or after January 1, 2012 and disposed of after that date, cost basis will be reported to shareholders and the Internal Revenue Service. Cost basis will be calculated using the Fund's default method, unless the shareholder instructs the Fund to use a different calculation method. Shareholders should carefully review the cost basis information provided by the Fund and make any additional basis, holding period or other adjustments that are required when reporting these amounts on their federal income tax returns. If you hold your Fund shares through a broker (or other nominee), the shareholder should contact that broker (nominee) with respect to reporting of cost basis and available elections for their account. For more information about the cost basis methods offered by Invesco, please refer to the Tax Center located under the Accounts & Services menu of our website at www.invesco.com/us.

It is possible, although the Fund believes it is unlikely, that, in connection with a repurchase offer, distributions to tendering shareholders may be subject to tax as ordinary income (rather than as gain or loss).

Backup withholding rules require the Fund, in certain circumstances, to withhold federal income tax from dividends and certain other payments, including repurchase proceeds, paid to shareholders who do not furnish to the Fund their correct taxpayer identification number (in the case of individuals, their social security number) and make certain required certifications (including certifications as to foreign status, if applicable), or who are otherwise subject to backup withholding. Under the Foreign Account Tax Compliance Act (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 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). The Fund may disclose the information that it receives from its shareholders to the Internal Revenue Service, 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 the Fund fails to provide the Fund with appropriate certifications or other documentation concerning its status under FATCA.

The federal income tax discussion set forth above is for general information only. Shareholders and prospective investors should consult their own advisers regarding the specific federal income tax consequences of purchasing, holding and disposing of Shares of the Fund, as well as the effects of state, local and foreign tax laws and any proposed tax law changes. For more information, see the "Taxation" section in the Fund's Statement of Additional Information.

GENERAL INFORMATION

The Fund is registered under the Investment Company Act of 1940 (the "1940 Act") as a closed-end management investment company, and is "diversified" for purposes of the 1940 Act. It was organized as a Massachusetts business trust on July 14, 1989, and was redomesticated as a Delaware Statutory Trust on October 15, 2012. Prior to December 2012, the Fund's name was Invesco Van Kampen Senior Loan Fund. Prior to June 2010, the Fund's name was Van Kampen Senior Loan Fund. On January 26, 2018, Class B shares of the Fund converted to Class A shares; Class B shares are no longer offered by the Fund.

INVESTMENT OBJECTIVE, INVESTMENT STRATEGIES AND RISKS

The Fund's investment objective is to provide a high level of current income, consistent with preservation of capital. The Fund invests primarily in adjustable rate senior loans ("Senior Loans"). Although the Fund's net asset value will vary, the Fund's policy of acquiring interests in floating or variable rate Senior Loans should minimize the fluctuations in the Fund's net asset value as a result of changes in interest rates. The Fund's net asset value may be affected by changes in borrower credit quality and other factors with respect to Senior Loan interests in which the Fund invests. An investment in the Fund may not be appropriate for all investors and is not intended to be a complete investment program. No assurance can be given that the Fund will achieve its investment objective. For further discussion of the characteristics of Senior Loan interests and associated special risk considerations, see "Investment Objective" and "Principal Investment Strategies of the Fund" and "Principal Risks of Investing in the Fund" in the Prospectus.

Temporary Defensive Strategies

The Fund may invest up to 100% of its assets in investments that may be inconsistent with its principal investment strategies for temporary defensive purposes in anticipation of or in response to adverse market, economic, political or other conditions. As a result, the Fund may not achieve its investment objective.

INVESTMENT RESTRICTIONS

The Fund's investment objective and the following investment restrictions are fundamental and cannot be changed without the approval of the holders of a majority (defined as the lesser of (i) 67% or more of the voting securities present at a meeting of shareholders, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy at such meeting, or (ii) more than 50% of the outstanding voting securities) of the Fund's outstanding Shares. All other investment policies or practices are considered by the Fund not to be fundamental and accordingly may be changed without shareholder approval. Unless the Fund's prospectus or this SAI states that a percentage limitation or fundamental or non-fundamental restriction applies on an ongoing basis, it applies only at the time the Fund makes an investment.That means the Fund is not required to sell securities to meet the percentage limits or investment restrictions if the value of the investment increases in proportion to the size of a Fund. Percentage limits on borrowing apply on an ongoing basis. With respect to the limitations on the issuance of senior securities, the percentage limitations apply at the time of purchase and on an ongoing basis. In accordance with the foregoing, the Fund may not:

1. Purchase any securities (other than obligations issued or guaranteed by the United States Government or by its agencies or instrumentalities), if as a result more than 5% of the Fund's total assets would then be invested in securities of a single issuer or if as a result the Fund would hold more than 10% of the outstanding voting securities of any single issuer; provided that, with respect to 50% of the Fund's assets, the Fund may invest up to 25% of its assets in the securities of any one issuer. For purposes of this restriction, the term issuer includes both the Borrower under a Loan Agreement and the Lender selling a Participation to the Fund together with any other persons interpositioned between such Lender and the Fund with respect to a Participation.

2. Purchase any security if, as a result of such purchase, more than 25% of the Fund's total assets (taken at current value) would be invested in the securities of Borrowers and other issuers having their principal business activities in the same industry (the electric, gas, water and telephone utility industries, commercial

banks, thrift institutions and finance companies being treated as separate industries for purposes of this restriction); provided, that this limitation shall not apply with respect to obligations issued or guaranteed by the U.S. Government or by its agencies or instrumentalities.

3. Issue senior securities nor borrow money, except that the Fund may issue senior securities or borrow money to the extent permitted by (i) the 1940 Act, (ii) the rules or regulations promulgated by the Commission under the 1940 Act, or (iii) an exemption or other relief applicable to the Fund from the provisions of the 1940 Act.

4. Make loans of money or property to any person, except for obtaining interests in Senior Loans in accordance with its investment objective, through loans of portfolio securities or the acquisition of securities subject to repurchase agreements.

5. Buy any security "on margin." Neither the deposit of initial or variation margin in connection with hedging transactions nor short-term credits as may be necessary for the clearance of such transactions is considered the purchase of a security on margin.

6. Sell any security "short," write, purchase or sell puts, calls or combinations thereof, or purchase or sell financial futures or options, except to the extent that the hedging transactions in which the Fund may engage would be deemed to be any of the foregoing transactions.

7. Act as an underwriter of securities, except to the extent the Fund may be deemed to be an underwriter in connection with the sale of or granting of interests in Senior Loans or other securities acquired by the Fund.

8. Make investments for the purpose of exercising control or participation in management, except to the extent that exercise by the Fund of its rights under Loan Agreements would be deemed to constitute such control or participation.

9. Buy or sell oil, gas or other mineral leases, rights or royalty contracts except pursuant to the exercise by the Fund of its rights under Loan Agreements. In addition, the Fund may purchase securities of issuers which deal in, represent interests in or are secured by interests in such leases, rights or contracts.

10. Purchase or sell real estate, commodities or commodities contracts except pursuant to the exercise by the Fund of its rights under Loan Agreements, except to the extent the interests in Senior Loans the Fund may invest in are considered to be interests in real estate, commodities or commodities contracts and except to the extent that hedging instruments the Fund may invest in are considered to be commodities or commodities contracts.

11. Notwithstanding the investment policies and restrictions of the Fund, upon approval of the Board of Trustees, the Fund may invest all or part of its investable assets in a management investment company with substantially the same investment objective, policies and restrictions as the Fund.

The latter part of one of the Fund's fundamental investment restrictions (i.e., the reference to "to the extent permitted by (i) the 1940 Act, (ii) the rules and regulations promulgated by the Commission under the 1940 Act, or (iii) an exemption or other relief applicable to the Fund from the provisions of the 1940 Act") provides the Fund with flexibility to change its limitations in connection with changes in applicable law, rules, regulations or exemptive relief. The language used in the restriction provides the necessary flexibility to allow the Fund's Board to respond efficiently to these kinds of developments without the delay and expense of a shareholder meeting.

Business Continuity and Operational Risk

The Adviser, the Fund and the Fund's 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 Fund or the Fund's 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 Fund, 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 Fund for extended periods of time. These circumstances could cause disruptions and negatively impact the Fund's service providers and the Fund's business operations, potentially including an inability to process Fund shareholder transactions, an inability to calculate the Fund's net asset value and price the Fund's investments, and impediments to trading portfolio securities.

Risks Related to Russian Invasion of Ukraine.

In late February 2022, Russian military forces invaded Ukraine, significantly amplifying already existing geopolitical tensions among Russia, Ukraine, Europe, NATO, and the West. Russia's invasion, the responses of countries and political bodies to Russia's actions, and the potential for wider conflict may increase financial market volatility and could have severe adverse effects on regional and global economic markets, including the markets for certain securities and commodities such as oil and natural gas. Following Russia's actions, various countries, including the U.S., Canada, the United Kingdom, Germany, and France, as well as the European Union, issued broad-ranging economic sanctions against Russia. The sanctions consist of the prohibition of trading in certain Russian securities and engaging in certain private transactions, the prohibition of doing business with certain Russian corporate entities, large financial institutions, officials and oligarchs, and the freezing of Russian assets. The sanctions include a commitment by certain countries and the European Union to remove selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications, commonly called "SWIFT", the electronic network that connects banks globally, and imposed restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. A number of large corporations and U.S. states have also announced plans to divest interests or otherwise curtail business dealings with certain Russian businesses.

The imposition of these current sanctions (and potential further sanctions in response to continued Russian military activity) and other actions undertaken by countries and businesses may adversely impact various sectors of the Russian economy, including but not limited to, the financials, energy, metals and mining, engineering, and defense and defense-related materials sectors. Such actions also may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble, and could impair the ability of a Fund to buy, sell, receive, or deliver those securities. Moreover, the measures could adversely affect global financial and energy markets and thereby negatively affect the value of the Fund's investments beyond any direct exposure to Russian issuers or those of adjoining geographic regions. In response to sanctions, the Russian Central Bank raised its interest rates and banned sales of local securities by foreigners. Russia may take additional counter measures or retaliatory actions, which may further impair the value and liquidity of Russian securities and Fund investments. Such actions could, for example, include restricting gas exports to other countries, seizure of U.S. and European residents' assets, or undertaking or provoking other military conflict elsewhere in Europe, any of which could exacerbate negative consequences on global financial markets and the economy. The actions discussed above could have a negative effect on the performance of Funds that have exposure to Russia. While diplomatic efforts have been ongoing, the conflict between Russia and Ukraine is currently unpredictable and has the potential to result in broadened military actions. The duration of ongoing hostilities and corresponding sanctions and related events cannot be predicted and may result in a negative impact on performance and the value of Fund investments, particularly as it relates to Russia exposure.

Cybersecurity Risk

With the increased use of technologies such as the Internet to conduct business, the Funds, like all companies, may be susceptible to operational,information security and related risks. Cybersecurity incidents involving the Funds and their service providers (including,without limitation,a Fund's investment adviser,sub-adviser,fund accountant, custodian, transfer agent and financial intermediaries) have the ability to cause

disruptions and impact business operations, potentially resulting in financial losses, impediments to trading,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.

Cybersecurity incidents can result from deliberate cyberattacks or unintentional events and may arise from external or internal sources. Cyberattacks may include infection by malicious software or gaining unauthorized access to digital systems, networks or devices that are used to service the Funds' operations (e.g., by "hacking" or "phishing"). Cyberattacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). These cyberattacks could cause the misappropriation of assets or personal information, corruption of data or operational disruptions. Geopolitical tensions may, from time to time, increase the scale and sophistication of deliberate cyberattacks.

Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Funds invest, counterparties with which the Funds engage, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies, other financial institutions and other parties. In addition, substantial costs may be incurred in order to prevent any cybersecurity incidents in the future. Although the Funds' service providers may have established business continuity plans and risk management systems to mitigate cybersecurity risks, there can be no guarantee or assurance that such plans or systems will be effective, or that all risks that exist, or may develop in the future, have been completely anticipated and identified or can be protected against. The Funds and their shareholders could be negatively impacted as a result.

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 (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, defaults and credit downgrades, among 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 and cause general concern and uncertainty. The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on a Fund's performance

Non-Fundamental Policies

For purposes of investment restriction number 2, the Fund has adopted supplementally a more restrictive non-fundamental investment policy that in effect changes the phrase "more than 25%" to "25% or more." For purposes of investment restriction number 2 and the supplement just described, the Fund will consider all relevant factors in determining whether to treat the Lender selling a Participation and any persons interpositioned between such Lender and the Fund as an issuer, including: the terms of the Loan Agreement and other relevant agreements (including inter-creditor agreements and any agreements between such

person and the Fund's custodian); the credit quality of such Lender or interpositioned person; general economic conditions applicable to such Lender or interpositioned person; and other factors relating to the degree of credit risk, if any, of such Lender or interpositioned person incurred by the Fund. With respect to the fundamental investment restriction number 4 regarding the loan of portfolio securities, although the Fund is permitted under such restriction to make loans of its portfolio securities, the Fund does not currently have an intention to do so. The Fund intends to reserve against such contingent obligations by segregating cash, liquid securities and liquid Senior Loans as a reserve.

The Fund has adopted additional fundamental policies in relation to its repurchase offers, which similarly cannot be changed without the approval of the holders of a majority of the Fund's outstanding Shares. A description of these policies is provided in the Fund's Prospectus under the heading "Repurchase of Shares."

The Fund generally will not engage in the trading of securities for the purpose of realizing short-term profits, but it will adjust its portfolio as it deems advisable in view of prevailing or anticipated market conditions to accomplish the Fund's investment objective. For example, the Fund may sell portfolio securities in anticipation of a movement in interest rates. Frequency of portfolio turnover will not be a limiting factor if the Fund considers it advantageous to purchase or sell securities. The Fund anticipates that the annual portfolio turnover rate of the Fund will not be in excess of 100%. A high rate of portfolio turnover involves correspondingly greater expenses than a lower rate, which expenses must be borne by the Fund and its shareholders.

Fund Structure. The Fund's fundamental investment policies and restrictions give the Fund the flexibility to pursue its investment objective through a fund structure commonly known as a "master-feeder" structure. If the Fund converts to a master-feeder structure, the existing shareholders of the Fund would continue to hold their Shares of the Fund and the Fund would become a feeder-fund of the master-fund. The value of a shareholder's Shares would be the same immediately after any conversion as the value immediately before such conversion. Use of this master-feeder structure potentially would result in increased assets invested among the collective investment vehicle of which the Fund would be a part, thus allowing operating expenses to be spread over a larger asset base, potentially achieving economies of scale. Any such conversion to a master-feeder structure would be effected by the Board of Trustees without a shareholder vote. In such case, the Fund would inform shareholders of this conversion by supplementing the Fund's Prospectus. The Fund's Board of Trustees presently does not intend to effect any conversion of the Fund to a master-feeder structure.

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 thirteen Trustees, including twelve 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, 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 a whole or the Committees also receive special written reports or presentations on a variety of risk issues at the request of the Board or a Committee.

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.

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.

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

Five retired Trustees, as well as Messrs. LaCava, Motley, Troccoli, Vandivort, 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.

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.

Purchase of Class A Shares of the Fund at Net Asset Value

The Trustees and certain other affiliated persons of the Fund may purchase Class A shares of the Invesco Funds without paying an initial sales charge. Invesco Distributors permits such purchases because there is a reduced sales effort involved in sales to such purchasers, thereby resulting in relatively low expenses of distribution. For a complete description of the persons who will not pay an initial sales charge on purchases of Class A shares of the Fund, see "Purchases of Shares -Class A Shares" in the prospectus.

Purchases of Class Y Shares of the Fund

The Trustees and certain other affiliated persons of the Fund may purchase Class Y shares of the Fund. For a description, please see "Purchases of Shares - Class Y Shares" in the prospectus.

Code of Ethics

Invesco, the Fund, 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 Fund 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. The codes of ethics are available on the EDGAR Database on the SEC's Internet site at https://www.sec.gov and copies may be obtained, after paying a duplicating fee, by electronic request at the following email address:[email protected].
