Invesco Advisers, Inc. (Invesco or the Adviser) has contractually agreed to waive a portion of the Fund’s management fee in an amount equal to the net management fee that Invesco earns on the Fund’s investments in certain affiliated funds, which will have the effect of reducing the Acquired Fund Fees and Expenses. Unless Invesco continues the fee waiver agreement, it will terminate on June 30, 2024. During its term, the fee waiver agreement cannot be terminated or amended to reduce the advisory fee waiver without approval of the Board of Trustees.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

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

	1 Year	3 Years	5 Years	10 Years
Class A	$355	$581	$824	$1,522

Class C	$259	$495	$854	$1,732

Class R	$133	$417	$723	$1,589

Class Y	$83	$261	$454	$1,013

Class R5	$81	$254	$443	$989

Class R6	$74	$232	$405	$906

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

	1 Year	3 Years	5 Years	10 Years
Class A	$355	$581	$824	$1,522

Class C	$159	$495	$854	$1,732

Class R	$133	$417	$723	$1,589

Class Y	$83	$261	$454	$1,013

Class R5	$81	$254	$443	$989

Class R6	$74	$232	$405	$906

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 43% of the average value of its portfolio.

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 secured floating rate loans made by banks and other lending institutions, senior secured floating rate debt instruments, and derivatives and other instruments that have economic characteristics similar to such securities. The Fund’s portfolio managers select the Fund’s portfolio investments by actively employing environmental, social and governance (ESG) criteria in the investment selection process described below, except as otherwise indicated.

Floating rate loans (also known as bank loans) are made to or issued by companies (borrowers), which may include U.S. and non-U.S. companies, and bear interest at a floating rate that resets periodically based on a benchmark that reflects current interest rates. Secured floating rate loans are often issued in connection with recapitalizations, acquisitions, leveraged buyouts and refinancings. Floating rate loans are typically structured and administered by a financial institution that acts as agent for the lenders in the lending group.

Floating rate loans will generally be purchased from banks or other financial institutions through assignments or participations. A direct interest in a floating rate loan may be acquired directly from the agent or another lender by assignment or an indirect interest may be acquired as a participation in another lender’s portion of a floating rate loan.

The Fund may invest up to 100% of its net assets in floating rate loans and floating rate debt securities that are determined to be below investment grade. Such floating rate debt securities are commonly referred to as “junk bonds”. 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

1 Invesco Floating Rate ESG Fund

by Invesco Advisers, Inc. (Invesco or the Adviser) to be of comparable quality, each at the time of purchase. The Fund may invest in defaulted or distressed loans and loans to bankrupt companies.

The Fund may invest up to 100% of its net assets in floating rate loans and floating rate debt securities of non-U.S. borrowers or issuers.

The Fund may invest in collateralized loan obligations (CLOs), which are debt instruments backed solely by a pool of other debt securities. CLOs where the CLO securities held by the Fund are in the senior classes with a floating rate of return will be counted toward the Fund’s 80% investment policy described above and are subject to application of the portfolio managers’ ESG criteria with respect to CLOs, as described below.

The Fund can invest up to 20% of its total assets in certain other types of debt obligations or securities and equity securities (including common stocks, preferred stocks, rights, warrants, and securities convertible into common stock), both to increase yield and to manage cash flow. Other types of debt obligations and securities may include unsecured loans, fixed rate high yield bonds, investment grade corporate bonds, and short-term government and commercial debt obligations. The Fund may also invest in CLO securities that are in the subordinated debt tranches of a CLO. Up to 5% of the Fund’s net assets may be invested in subordinated loans. Some of the floating rate loans and debt securities in which the Fund may invest will be considered to be illiquid.

The Fund can invest in derivative instruments including forward foreign currency contracts, futures contracts and swap contracts. 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 hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. 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 can use currency swaps to hedge its exposure to foreign currencies. The Fund can also use swap contracts, including credit default swaps, and can invest in credit linked notes, to gain or reduce exposure to an asset class or a particular issuer.

The portfolio managers’ ESG criteria will apply to derivatives and other instruments that have economic characteristics similar to senior secured floating rate loans made by banks and other lending institutions and senior secured floating rate debt instruments as reflected in the Fund’s 80% investment policy. However, the Adviser’s ESG criteria will not apply to the Fund’s investments in derivatives for currency hedging purposes.

The Fund invests in loans and debt securities selected by the Fund’s portfolio managers based on a fundamental bottom-up risk assessment of each issuer and issue, combined with a top-down macro and sector overlay. The portfolio managers construct the Fund’s portfolio using a process that focuses on obtaining access to the widest possible range of potential investments available in the market and ongoing credit analysis of issuers. The portfolio managers perform their own independent credit analysis on each borrower and the collateral securing each loan, considering 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.

For each investment opportunity, the portfolio managers undertake a comprehensive due diligence review of the issuer, including in-depth meetings with the issuer’s management team, the financial sponsor (if applicable), and the industry in which the issuer competes, as well as engages in discussions with third party industry experts to assess credit risk and gain a detailed understanding of the company and the industry. The portfolio managers’ due diligence looks at detailed cash flow models, credit and relative value comparable company analyses, and structural terms of the loan. The portfolio managers also analyze each company to determine its earnings potential and other factors indicating the sustainability of debt repayment. The analysis concludes with an investment thesis and recommendation that includes an internal risk rating derived from the

portfolio managers’ view of the issuer’s probability of default and estimated recovery ratings.

Additionally, as part of the credit selection and portfolio construction process, the Fund employs a proprietary framework for evaluating each issuer based on ESG criteria the portfolio managers have determined to be important in the investment selection process. The Fund’s ESG methodology actively utilizes both proprietary ESG scoring and ESG exclusionary screening to construct the Fund’s portfolio. The portfolio managers apply their ESG criteria in an effort to assess an issuer’s impact of business operations on the environment, the social impact its business has on internal and external communities, and the quality of its corporate governance principles.

Under normal market conditions, the portfolio managers will employ the following ESG methodology to assess investment opportunities for the Fund’s portfolio (except with respect to CLOs, which employ a different ESG methodology described below): The portfolio managers first employ a proprietary ESG screen to exclude issuers from the investment universe of securities in which the Fund may invest that do not meet its investment criteria. Such excluded issuers are those with substantial involvement in the production of tobacco products, controversial weapons, engagement in cultivation, production or distribution of recreational cannabis, extraction of thermal coal, and extraction of fossil fuels from unconventional sources. Issuers involved in the generation of electricity above 30% from coal-fired plants are also excluded. Issuers will also be excluded based on their non-compliance with UN Global Compact principles. The principles of the UN Global Compact represent a set of values that the UN believes responsible businesses should incorporate into their operations in order to meet fundamental responsibilities in the areas of human rights, labor, environment and anti-corruption. To the extent an issuer’s status changes to meet the qualification for exclusion, the Fund shall take steps to divest its holdings of the issuer within a reasonable period of time. Because the Fund's divestment of such investments may not be immediate, the Fund could be invested in investments that do meet the qualification for exclusion. This screening criteria may be updated periodically.

Next, based on research and due diligence reviews conducted with the management teams of the eligible issuers, each investment opportunity is scored by the portfolio management team on a scale of 1-5 for risks related to multiple ESG factors under each individual pillar of the ESG framework (1 indicates “no risk” and 5 indicates “high risk”). The environmental pillar (“E”) factors include natural resources, pollution and waste, supply chain impact, and environmental opportunities. The social pillar (“S”) factors include workforce, community, product responsibility, and human rights. The governance pillar (“G”) factors include management, shareholders, board of directors, auditors, regulatory issuers, corporate social responsibility strategy, anti-corruption, and business ethics. The foregoing factors in each ESG pillar may be updated periodically.

Each investment opportunity is assigned a weighted average score for each ESG pillar. An overall aggregated, or composite, ESG score is also calculated, with pillars weighted differently depending on the industry. The scores are determined at the time of purchase and reviewed at least annually. The Fund will not invest in loans or securities from issuers that have a composite ESG rating or single category E, S, or G pillar rating above levels set within the internal ESG rating methodology, and will seek to divest within a reasonable period of time from investments for which the aggregate ESG rating or single category E, S, or G ratings rise above these limits, as determined by the portfolio managers’ internal rating methodology. Because the Fund's divestment of such investments may not be immediate, the Fund could be invested in investments that do meet the qualification for exclusion. Under normal circumstances, pursuant to its current internal limits, the Fund will only invest in loans from issuers with a single category E, S or G pillar score of 4.25 and under and will also only invest in loans from issuers with a composite ESG score of 4.0 and under.

With regard to the application of the Fund’s ESG methodology to CLOs, the portfolio managers will utilize a proprietary approach in selecting CLOs

2 Invesco Floating Rate ESG Fund

for investment. The portfolio managers will assess via their due diligence process how a CLO manager incorporates ESG considerations into its asset selection process. The portfolio managers examine and assess the following ESG considerations with respect to the CLO manager: the existence of an ESG practice that definitively includes/excludes borrowers as eligible investments; the number of the CLO’s investments that must be ESG-rated prior to becoming an eligible investment; the extent to which the ESG ratings process results in a quantitative evaluation; the existence of an exclusionary/screening policy that prohibits investments in certain companies based on ESG considerations; the extent to which formal control procedures are in place to ensure consistency and compliance with ESG policies; the frequency with which ESG ratings are evaluated; and the extent to which the CLO manager is a signatory to UN-backed principles of responsible investment. Based on those considerations, the portfolio managers assign quantitative factor ratings to each CLO manager in order to assess how that manager evaluates the different E, S and G risks within their portfolio and determine a cumulative CLO manager ESG score. Only CLO managers whose ESG practices meet the Fund’s internal ESG standards based on the above considerations and quantitative factor ratings will become an eligible CLO manager. The CLO manager screen will be reviewed and updated at least annually.

Decisions to purchase or sell loans and other investments 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, situation-specific opportunities and application of the Fund’s ESG criteria. The purchase or sale of loans and other investments may be related to a decision to alter the Fund’s macro risk exposure, a desire to limit or reduce the Fund’s exposure to a particular security or issuer, the degradation of an issuer’s credit quality, an ESG screen or score, or the general liquidity needs of the Fund.

Principal Risks of Investing in the Fund

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

Bank Loan Risk. There are a number of risks associated with an investment in bank loans including credit risk, interest rate risk, liquidity risk, valuation risk and prepayment risk. These risks are typically associated with debt securities but may be heightened in part because of the limited public information regarding bank loans. 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 bank 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 bank loans is also directly tied to the risk of insolvency or bankruptcy of the issuing banks. The value of bank loans can be affected by and 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.

Bank 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.

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.

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.

ESG Risk. Because the Fund evaluates ESG factors to assess and exclude certain investments for non-financial reasons, it may forego some market opportunities available to funds that do not use these factors. The securities of issuers that score favorably under the Fund’s ESG scoring methodology may underperform similar issuers that do not score as well or may underperform the market as a whole. As a result, the Fund may underperform funds that do not screen or score issuers based on ESG factors or funds that use a different ESG methodology. Information used by the Fund to evaluate such factors may not be readily available, complete or accurate, which could negatively impact the Fund’s ability to apply its methodology, which in turn could negatively impact the Fund’s performance. In addition, the Fund’s assessment of an issuer, based on the issuer’s level of involvement in a particular industry or the issuer’s ESG score, may differ from that of other funds or an investor. As a result, the issuers deemed eligible for inclusion in the Fund’s portfolio may not reflect the beliefs or values of any particular investor and may not be deemed to exhibit positive or favorable ESG characteristics if different metrics were used to evaluate them.

3 Invesco Floating Rate ESG Fund

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.

Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in central bank policies could also result in higher than normal redemptions by shareholders, which could potentially increase the Fund’s portfolio turnover rate and transaction costs.

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.

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

Subordinated Debt Risk. Perpetual subordinated debt is a type of hybrid instrument that has no maturity date for the return of principal and does not need to be redeemed by the issuer. These investments typically have lower credit ratings and lower priority than other obligations of an issuer during bankruptcy, presenting a greater risk for nonpayment. This risk increases as the priority of the obligation becomes lower. Payments on these securities may be subordinated to all existing and future liabilities and obligations of subsidiaries and associated companies of an issuer. Additionally, some perpetual subordinated debt does not restrict the ability of an issuer’s subsidiaries to incur further unsecured indebtedness.

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.

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.

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 that apply to the underlying common stock. In addition, certain convertible

4 Invesco Floating Rate ESG Fund

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, which are considered to have more speculative characteristics and greater susceptibility to default or decline in market value than investment grade securities.

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

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.

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.

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.

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.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. For periods prior to August 21, 2020, performance shown is that of the Fund using its previous investment strategy, which did not apply ESG criteria. Therefore, the performance shown for periods prior to August 21, 2020 may have differed had the Fund’s current investment strategy been in effect. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund's performance to that of a broad-based securities market benchmark, a style-specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to those of the Fund (in that order). The Fund's past performance (before and after taxes) is not necessarily an indication of its future performance.

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

Ask your salesperson or financial adviser or visit your financial intermediary’s website for more information.

Investment Objective(s), Strategies, Risks and Portfolio Holdings

Objective(s) and Strategies

The Fund’s investment objective is total return, comprised of current income and capital appreciation. The Fund’s investment objective may be changed by the Board of Trustees (the Board) without shareholder approval.

6 Invesco Floating Rate ESG Fund

The Fund may invest up to 100% of its net assets in floating rate loans and floating rate debt securities that are determined to be below investment grade. Such floating rate debt securities are commonly referred to as “junk bonds”. Investment grade securities are: (i) securities rated BBB- or higher by S&P or Baa3 or higher by Moody’s or an equivalent rating by another 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 invest in defaulted or distressed loans and loans to bankrupt companies.

The Fund may invest up to 100% of its net assets in floating rate loans and floating rate debt securities of non-U.S. borrowers or issuers.

The Fund can invest in derivative instruments including forward foreign currency contracts, futures contracts and swap contracts. 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. 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. The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

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.

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 can use currency swaps

to hedge its exposure to foreign currencies. The Fund can also use swap contracts, including credit default swaps, to gain or reduce exposure to an asset class or a particular issuer.

The Fund can invest in credit linked notes. Credit linked notes are securities structured and issued by an issuer, which may be a bank, banker or special purpose vehicle. The credit linked note’s price or coupon is linked to the performance of the reference asset of the second party. Generally, the credit linked note holder receives either a fixed or floating coupon rate during the life of the credit linked note and par at maturity. The cash flows are dependent on specified credit-related events. Should the second party default or declare bankruptcy, the credit linked note holder will receive an amount equivalent to the recovery rate and may not receive any compensation. In return for these risks, the credit linked note holder receives a higher yield. The Fund can use credit linked notes to gain or reduce exposure to an asset class or a particular issuer.

thermal coal, and extraction of fossil fuels from unconventional sources. Issuers involved in the generation of electricity above 30% from coal-fired plants are also excluded. Issuers will also be excluded based on their non-compliance with UN Global Compact principles. The principles of the UN Global Compact represent a set of values that the UN believes responsible businesses should incorporate into their operations in order to meet fundamental responsibilities in the areas of human rights, labor, environment and anti-corruption. They are derived from the Universal Declaration of Human Rights, the International Labour Organization’s Declaration on Fundamental Principles and Rights at Work, the Rio Declaration on Environment and Development, and the United Nations Convention Against Corruption. The UN principles embody the idea that responsible companies’ business practices should reflect: (1) protection of internationally proclaimed human rights; (2) not being complicit in human rights abuses; (3) freedom of association and the right to collective bargaining; (4) elimination of forced and compulsory labor; (5) abolition of child labor; (6) elimination of discrimination in employment and occupation; (7) supporting a precautionary approach to environmental challenges; (8) promoting greater environmental responsibility; (9) development and diffusion of environmentally friendly technologies, and (10) working against corruption, including extortion and bribery. To the extent an issuer’s status changes to meet the qualification for exclusion, the Fund shall take steps to divest its holdings of the issuer within a reasonable period of time. Because the Fund's divestment of such investments may not be immediate, the Fund could be invested in investments that do meet the qualification for exclusion. This screening criteria may be updated periodically.

With regard to the application of the Fund’s ESG methodology to CLOs, the portfolio managers will utilize a proprietary approach in selecting CLOs for investment. The portfolio managers will assess via their due diligence process how a CLO manager incorporates ESG considerations into its asset selection process. The portfolio managers examine and assess the following ESG considerations with respect to the CLO manager: the existence of an ESG practice that definitively includes/excludes borrowers as eligible investments; the number of the CLO’s investments that must be ESG-rated prior to becoming an eligible investment; the extent to which the ESG ratings process results in a quantitative evaluation; the existence of an

exclusionary/screening policy that prohibits investments in certain companies based on ESG considerations; the extent to which formal control procedures are in place to ensure consistency and compliance with ESG policies; the frequency with which ESG ratings are evaluated; and the extent to which the CLO manager is a signatory to UN-backed principles of responsible investment. Based on those considerations, the portfolio managers assign quantitative factor ratings to each CLO manager in order to assess how that manager evaluates the different E, S and G risks within their portfolio and determine a cumulative CLO manager ESG score. Only CLO managers whose ESG practices meet the Fund’s internal ESG standards based on the above considerations and quantitative factor ratings will become an eligible CLO manager. The CLO manager screen will be reviewed and updated at least annually.

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.

For more information, see “Description of the Funds and Their Investments and Risks” in the Fund’s SAI.

Risks

The principal risks of investing in the Fund are:

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.

◾

Market Disruption Risks Related to Russia-Ukraine Conflict. Following Russia’s invasion of Ukraine in late February 2022, various countries, including the United States, as well as North Atlantic Treaty Organization (NATO) member countries and the European Union, issued broad-ranging economic sanctions against Russia. The war in Ukraine (and the potential for further sanctions in response to

8 Invesco Floating Rate ESG Fund

Russia’s continued military activity) may escalate. These and other corresponding events, have had, and could continue to have, severe negative effects on regional and global economic and financial markets, including increased volatility, reduced liquidity, and overall uncertainty. The negative impacts may be particularly acute in certain sectors including, but not limited to, energy and financials. Russia may take additional countermeasures or retaliatory actions (including cyberattacks), which could exacerbate negative consequences on global financial markets. The duration of the conflict and corresponding sanctions and related events cannot be predicted. The foregoing may result in a negative impact on Fund performance and the value of an investment in the Fund, even beyond any direct investment exposure the Fund may have to Russian issuers or the adjoining geographic regions.

◾

COVID-19. The “COVID-19” strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally 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 the Fund’s performance.

The risk of holding bank loans is also directly tied to the risk of insolvency or bankruptcy of the issuing banks. If the borrower defaults on its obligation to pay, there is the possibility that the collateral securing a loan, if any, may be difficult to liquidate or be insufficient to cover the amount owed under the loan. The value of bank loans can be affected by and 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. Additionally, valuation of bank loans may require greater research due to limited public information available and elements of judgment may play a greater role in valuation since there may be a lack of objective data available.

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.

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),

9 Invesco Floating Rate ESG Fund

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.

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.

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

Subordinated Debt Risk. Perpetual subordinated debt is a type of hybrid instrument that has no maturity date for the return of principal and does not need to be redeemed by the issuer. These investments typically have lower credit ratings and lower priority than other obligations of an issuer during bankruptcy, presenting a greater risk for nonpayment. This risk increases as the priority of the obligation becomes lower. Payments on these securities may be subordinated to all existing and future liabilities and obligations of subsidiaries and associated companies of an issuer. Claims of creditors of such subsidiaries and associated companies will have priority over the issuer and the Fund to the assets of those subsidiaries and associated companies. Additionally, some perpetual subordinated debt does not restrict the ability of an issuer’s subsidiaries to incur further unsecured indebtedness.

Credit Quality Risk. The Fund can invest in securities that are rated or unrated. “Investment-grade” securities are those rated within the four highest rating categories by nationally recognized statistical rating organizations such as Moody’s or S&P (or, in the case of unrated securities, determined by the investment adviser to be comparable to securities rated

investment-grade). “Below-investment-grade” securities are those that are rated below those categories, which are also referred to as “junk bonds.” While securities rated within the fourth highest category by S&P (meaning BBB+, BBB or BBB-) or by Moody’s (meaning Baa1, Baa2 or Baa3) are considered “investment-grade,” they have some speculative characteristics. If two or more nationally recognized statistical rating organizations have assigned different ratings to a security, the investment adviser uses the highest rating assigned.

Credit ratings evaluate the expectation that scheduled interest and principal payments will be made in a timely manner. They do not reflect any judgment of market risk. Ratings and market value may change from time to time, positively or negatively, to reflect new developments regarding the issuer. Rating organizations might not change their credit rating of an issuer in a timely manner to reflect events that could affect the issuer’s ability to make timely payments on its obligations. In selecting securities for its portfolio and evaluating their income potential and credit risk, the Fund does not rely solely on ratings by rating organizations but evaluates business, economic and other factors affecting issuers as well. Many factors affect an issuer’s ability to make timely payments, and the credit risk of a particular security may change over time. The investment adviser also may use its own research and analysis to assess those risks. If a bond is insured, it will usually be rated by the rating organizations based on the financial strength of the insurer. The rating categories are described in an Appendix to the SAI.

Unrated Securities Risk. The investment adviser may internally assign ratings to securities that are not rated by any nationally recognized statistical rating organization, after assessing their credit quality and other factors, in categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the investment adviser’s credit analysis process is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization. Unrated securities are considered “investment-grade” or “below-investment-grade” if judged by the investment adviser to be comparable to rated investment-grade or below-investment-grade securities. The investment adviser’s rating does not constitute a guarantee of the credit quality. In addition, some unrated securities may not have an active trading market or may trade less actively than rated securities, which means that the Fund might have difficulty selling them promptly at an acceptable price.

In evaluating the credit quality of a particular security, whether rated or unrated, the investment adviser will normally take into consideration a number of factors such as, if applicable, the financial resources of the issuer, the underlying source of funds for debt service on a security, the issuer’s sensitivity to economic conditions and trends, any operating history of the facility financed by the obligation, the degree of community support for the financed facility, the capabilities of the issuer’s management, and regulatory factors affecting the issuer or the particular facility.

A reduction in the rating of a security after the Fund buys it will not require the Fund to dispose of the security. However, the investment adviser will evaluate such downgraded securities to determine whether to keep them in the Fund’s portfolio.

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.

Foreign Securities Risk. The value of the Fund's foreign investments may be adversely affected by political and social instability in the home

10 Invesco Floating Rate ESG Fund

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.

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.

Preferred Securities Risk. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred stock has a set dividend rate and ranks ahead of common stocks and behind debt securities in claims for dividends and for assets of the issuer in a liquidation or bankruptcy. Preferred securities also may be subordinated to bonds or other debt instruments in an issuer’s capital

structure, subjecting them to a greater risk of non-payment than these more senior securities. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer.

Rights and Warrants Risk. Rights and warrants may be purchased directly or acquired as part of other securities. Warrants are options to purchase equity securities at a specific price during a specific period of time. The price of a warrant does not necessarily move parallel to, and is generally more volatile than, the price of the underlying security. 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 value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Convertible securities can be converted into or exchanged for a set amount of common stock of an issuer within a particular period of time at a specified price or according to a price formula. Convertible debt securities pay interest and convertible preferred stocks pay dividends until they mature or are converted, exchanged or redeemed. Some convertible debt securities may be considered “equity equivalents” because of the feature that makes them convertible into common stock. Since a convertible security derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock. In addition, certain convertible securities are subject to involuntary conversions and may undergo principal write-downs upon the occurrence of certain triggering events. These convertible securities are subject to an increased risk of loss and are generally subordinate in rank to other debt obligations of the issuer. Convertible securities may be rated below investment grade, which are considered to have more speculative characteristics and greater susceptibility to default or decline in market value than investment grade securities.

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

11 Invesco Floating Rate ESG Fund

use of derivatives may include other, possibly greater, risks, which are described below.

◾

Counterparty Risk. Certain derivatives do not trade on an established exchange (referred to as over-the-counter (OTC) derivatives) and are simply financial contracts between the Fund and a counterparty. When the Fund is owed money on an OTC derivative, the Fund is dependent on the counterparty to pay or, in some cases, deliver the underlying asset, unless the Fund can otherwise sell its derivative contract to a third party prior to its expiration. Many counterparties are financial institutions such as banks and broker-dealers and their creditworthiness (and ability to pay or perform) may be negatively impacted by factors affecting financial institutions generally. In addition, in the event that a counterparty becomes bankrupt or insolvent, the Fund’s ability to recover the collateral that the Fund has on deposit with the counterparty could be delayed or impaired. For derivatives traded on a centralized exchange, the Fund generally is dependent upon the solvency of the relevant exchange clearing house (which acts as a guarantor for each contractual obligation under such derivatives) for payment on derivative instruments for which the Fund is owed money.

◾

Leverage Risk. Many derivatives do not require a payment up front equal to the economic exposure created by holding a position in the derivative, which creates a form of leverage. 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. In addition, some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. Leverage may therefore make the Fund’s returns more volatile and increase the risk of loss. 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.

◾

Liquidity Risk. There is a smaller pool of buyers and sellers for certain derivatives, particularly OTC derivatives, than more traditional investments such as stocks. These buyers and sellers are often financial institutions that may be unable or unwilling to buy or sell derivatives during times of financial or market stress. Derivative instruments may therefore be less liquid than more traditional investments and the Fund may be unable to sell or exit 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. To the extent that the Fund is unable to exit a derivative position because of market illiquidity, the Fund may not be able to prevent further losses of value in its derivatives holdings and the liquidity of the Fund and its ability to meet redemption requests may be impaired to the extent that a substantial portion of the Fund’s otherwise liquid assets must be used as margin. Another consequence of illiquidity is that the Fund may be required to hold a derivative instrument to maturity and take or make delivery of the underlying asset that the Adviser would otherwise avoid.

◾

Forward Contracts Risk. The projection of short-term currency market movements is extremely difficult, and the successful execution of a short-term hedging strategy is highly uncertain. The precise matching of the amounts under forward contracts and the value of the securities involved generally will not be possible because the future value of securities denominated in foreign currencies will change as a consequence of market movements between the date the forward contract is entered into and the date it is sold. Investments in forward 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.

◾

Futures Contracts Risk. The volatility of futures contracts prices has been historically greater than the volatility of stocks and bonds. The liquidity of the futures market depends on participants entering into offsetting transactions rather than making or taking delivery. To the extent participants decide to make or take delivery, liquidity in the futures market could be reduced. In addition, futures exchanges often impose a maximum permissible price movement on each futures contract for each trading session. The Fund may be disadvantaged if it is prohibited from executing a trade outside the daily permissible price movement.

◾

Swap Transactions Risk. Under U.S. financial reform legislation enacted in 2010, certain types of swaps are required to be executed on a regulated market and cleared through a central clearing house counterparty, which may entail further risks and costs for the Fund. Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract or may be centrally cleared. In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is submitted for clearing to a central clearing house counterparty, and the Fund faces the central clearing house counterparty by means of an account with a futures commission merchant that is a member of the clearing house.

◾

Other Risks. Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient, as described under the “Taxes” section of the prospectus. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Fund’s taxable income or gains, and may limit or prevent the Fund from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Fund to change its investment strategy. Derivatives strategies may not always be successful. For example, to the extent that the Fund uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Fund may not realize the intended benefits. There is also the risk that during adverse market conditions, an instrument which would usually operate as a hedge provides no hedging benefits at all. The Fund’s use of derivatives may be limited by the requirements for taxation of the Fund as a regulated investment company.

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.

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.

12 Invesco Floating Rate ESG Fund

Borrowing Risk. Borrowing money to buy securities exposes the Fund to leverage because the Fund seeks to achieve a return on a capital base larger than the assets that shareholders have contributed to the Fund. Borrowing 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. The Fund may also be required to liquidate positions when it may not be advantageous to do so in order to repay borrowed money when due. 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.

Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investments or investment strategies available to the Adviser in connection with managing the Fund, which may also adversely affect the ability of the Fund to achieve its investment objective.

Portfolio Holdings

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

Fund Management

The Adviser(s)

Invesco serves as the Fund’s investment adviser. The Adviser manages the investment operations of the Fund as well as other investment portfolios that encompass a broad range of investment objectives, and has agreed to perform or arrange for the performance of the Fund’s day-to-day management. The Adviser is located at 1555 Peachtree Street, N.E., Atlanta, Georgia 30309. The Adviser, as successor in interest to multiple investment advisers, has been an investment adviser since 1976.

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 provides portfolio management services to the Fund.

In addition, Invesco has entered into one or more Sub-Advisory Agreements with certain affiliates to serve as sub-advisers to the Fund (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 Fund. The Sub-Advisers and the Sub-Advisory Agreements are described in the SAI.

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.

Adviser Compensation

During the fiscal year ended August 31, 2022, the Adviser received compensation of 0.60% of the Fund’s average daily net assets, after fee waiver and/or expense reimbursement, if any.

Invesco, not the Fund, pays sub-advisory fees, if any.

A discussion regarding the basis for the Board’s approval of the investment advisory agreement and investment sub-advisory agreements of the Fund is available in the Fund’s most recent annual or semi-annual report to shareholders.

16 Invesco Floating Rate ESG Fund

Hypothetical Investment and Expense Information

In connection with the final settlement reached between Invesco and certain of its affiliates with certain regulators, including the New York Attorney General’s Office, the SEC and the Colorado Attorney General’s Office (the settlement) arising out of certain market timing and unfair pricing allegations made against Invesco and certain of its affiliates, Invesco and certain of its affiliates agreed, among other things, to disclose certain hypothetical information regarding investment and expense information to Fund shareholders. The chart below is intended to reflect the annual and cumulative impact of the Fund’s expenses, including investment advisory fees and other Fund costs, on the Fund’s returns over a 10-year period. The example reflects the following:

◾

You invest $10,000 in the Fund and hold it for the entire 10-year period;

◾

Your investment has a 5% return before expenses each year;

◾

The Fund’s current annual expense ratio includes, if applicable, any contractual fee waiver or expense reimbursement that would apply for the period for which it was committed;

◾

Hypotheticals both with and without any applicable initial sales charge applied; and

◾

There is no sales charge on reinvested dividends.

There is no assurance that the annual expense ratio will be the expense ratio for the Fund’s classes for any of the years shown. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

Shareholder Account Information

In addition to the Fund(s), the Adviser serves as investment adviser to many other Invesco mutual funds that are offered to investors (Invesco Funds or Funds). The following information is about all of the Invesco Funds and their share classes that have different fees and expenses.

Some investments in the Funds are made through accounts that are maintained by intermediaries (and not in the name of an individual investor) and some investments are made indirectly through products that use the Funds as underlying investments, such as Retirement and Benefit Plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the Funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the name of an individual investor), the intermediary or conduit investment vehicle may impose rules that differ from, and/or charge a transaction or other fee in addition to, those described in this prospectus. As a result, the availability of certain share classes and/or shareholder privileges or services described in this prospectus will depend on the policies, procedures and trading platforms of the financial intermediary or conduit investment vehicle. Accordingly, through your financial intermediary you may be invested in a share class that is subject to higher annual fees and expenses than other share classes that are offered in this prospectus. Investing in a share class subject to higher annual fees and expenses may have an adverse impact on your investment return. Please consult your financial adviser to consider your options, including your eligibility to qualify for the share classes and/or shareholder privileges or services described in this prospectus.

The Fund is not responsible for any additional share class eligibility requirements, investment minimums, exchange privileges, or other policies imposed by financial intermediaries or for notifying shareholders of any changes to them. Please consult your financial adviser or other financial intermediary for details.

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

◾

Employer Sponsored Retirement and Benefit Plans include (i) employer sponsored pension or profit sharing plans that qualify under section 401(a) of the Internal Revenue Code of 1986, as amended (the Code),

including 401(k), money purchase pension, profit sharing and defined benefit plans; (ii) 403(b) and non-qualified deferred compensation arrangements that operate similar to plans described under (i) above, such as 457 plans and executive deferred compensation arrangements; (iii) health savings accounts maintained pursuant to Section 223 of the Code; and (iv) voluntary employees’ beneficiary arrangements maintained pursuant to Section 501(c)(9) of the Code.

◾

Shareholder Account Information and additional information is available on the Internet at www.invesco.com/us. To access your account, go to the tab for “Account & Services,” then click on “Accounts Overview.” For additional information about Invesco Funds, consult the Fund’s prospectus and SAI, which are available on that same website or upon request free of charge. The website is not part of this prospectus.

Choosing a Share Class

Each Fund may offer multiple classes of shares and not all Funds offer all share classes discussed herein. Each class represents an interest in the same portfolio of investments. Certain classes have higher expenses than other classes which may lower the return on your investment when compared to a less expensive class. In deciding which class of shares to purchase, you should consider the following attributes of the various share classes, among other things: (i) the eligibility requirements that apply to purchases of a particular class and any eligibility requirements of your financial intermediary, (ii) the initial sales charges and contingent deferred sales charges (CDSCs), if any, applicable to the class, (iii) the 12b-1 fee, if any, paid by the class, and (iv) any services you may receive from a financial intermediary. Please contact your financial adviser to assist you in making your decision. Please refer to the prospectus fee table for more information on the fees and expenses of a particular Fund’s share classes.

Share Class Eligibility

The availability of certain share classes will depend on how you purchased your shares. Intermediaries may have different policies regarding the availability of certain share classes than those described below. You should consult your financial adviser to consider your options, including your eligibility to qualify for the share classes described below. The Fund is not responsible for eligibility requirements imposed by financial intermediaries or for notifying shareholders of any changes to them. See “Financial Intermediary-Specific Arrangements” for more information on certain intermediary-specific eligibility requirements. Please consult with your financial intermediary if you have any questions regarding their policies.

Class A, C and Invesco Cash Reserve Shares

Class A, C and Invesco Cash Reserve Shares are generally available to all retail investors, including individuals, trusts, corporations, business and charitable organizations and Retirement and Benefit Plans. Investors may only open an account to purchase Class C shares if they have appointed a financial intermediary that allows for new accounts in Class C shares to be opened. This restriction does not apply to Employer Sponsored Retirement and Benefit Plans. The share classes offer different fee structures that are intended to compensate financial intermediaries for services provided in connection with the sale of shares and continued maintenance of the customer relationship. You should consider the services provided by your financial adviser and any other financial intermediaries who will be involved in the servicing of your account when choosing a share class.

Class A2 Shares

Class A2 shares, which are offered only on Invesco Short Duration Inflation Protected Fund and Invesco Limited Term Municipal Income Fund, are closed to new investors. All references in this “Shareholder Account

Information” section of this prospectus to Class A shares shall include Class A2 shares, unless otherwise noted.

Class AX and CX Shares

Class AX and CX shares are closed to new investors. Only investors who have continuously maintained an account in Class AX or CX of a specific Fund may make additional purchases into Class AX and CX, respectively, of such specific Fund. All references in this “Shareholder Account Information” section of this prospectus to Class A, C or R shares of the Invesco Funds shall include Class AX (excluding Invesco Government Money Market Fund), or CX shares, respectively, of the Invesco Funds, unless otherwise noted. All references in this “Shareholder Account Information” section of this prospectus to Invesco Cash Reserve Shares of Invesco Government Money Market Fund shall include Class AX shares of Invesco Government Money Market Fund, unless otherwise noted.

Class P Shares

In addition to the other share classes discussed herein, the Invesco Summit Fund offers Class P shares, which were historically sold only through the AIM Summit Investors Plans I and II (each a Plan and, collectively, the Summit Plans). Class P shares are sold with no initial sales charge and have a 12b-1 fee of 0.10%. However, Class P shares are not sold to members of the general public. Only shareholders who had accounts in the Summit Plans at the close of business on December 8, 2006 may purchase Class P shares and only until the total of their combined investments in the Summit Plans and in Class P shares directly equals the face amount of their former Plan under the 30 year extended investment option. The face amount of a Plan is the combined total of all scheduled monthly investments under the Plan. For a Plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30 year extended investment option.

Class R Shares

Class R shares are intended for Retirement and Benefit Plans. Certain financial intermediaries have additional eligibility criteria regarding Class R shares. If you received Class R shares as a result of a merger or reorganization of a predecessor fund into any of the Funds, you will be permitted to make additional Class R shares purchases.

Class R5 and R6 Shares

Class R5 and R6 shares of the Funds (except for the Invesco Master Loan Fund) are available for use by Employer Sponsored Retirement and Benefit Plans, held either at the plan level or through omnibus accounts, that generally process no more than one net redemption and one net purchase transaction each day.

Class R5 and R6 shares of the Funds are also available to institutional investors. Institutional investors are: banks, trust companies, collective trust funds, entities acting for the account of a public entity (e.g., Taft-Hartley funds, states, cities or government agencies), funds of funds or other pooled investment vehicles, 529 college savings plans, financial intermediaries and corporations investing for their own accounts, endowments and foundations. For information regarding investment minimums for Class R5 and R6 shares, please see “Minimum Investments” below.

Class R6 shares of the Funds are also available through an intermediary that has agreed with Invesco Distributors, Inc. to make such shares

A-2 The Invesco Funds

available for use in retail omnibus accounts that generally process no more than one net redemption and one net purchase transaction each day.

The Invesco Master Loan Fund is only available for purchase by other Funds in the Invesco fund family and other Invesco pooled investment vehicles.

Shareholders eligible to purchase Class R6 Shares must meet the requirements specified by their intermediary. Not all intermediaries offer Class R6 Shares to their customers.

Class S Shares

Class S shares are limited to investors who purchase shares with the proceeds received from a systematic contractual investment plan redemption within the 12 months prior to purchasing Class S shares, and who purchase through an approved financial intermediary that has an agreement with the distributor to sell Class S shares. Class S shares are not otherwise sold to members of the general public. An investor purchasing Class S shares will not pay an initial sales charge. The investor will no longer be eligible to purchase additional Class S shares at that point where the value of the contributions to the prior systematic contractual investment plan combined with the subsequent Class S share contributions equals the face amount of what would have been the investor’s systematic contractual investment plan under the 30-year investment option. The face amount of a systematic contractual investment plan is the combined total of all scheduled monthly investments under that plan. For a plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30-year extended investment option.

Class Y Shares

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, (ii) endowments, foundations, or Employer Sponsored Retirement and Benefit Plans (with the exception of “Solo 401(k)” Plans and 403(b) custodial accounts held directly at Invesco), (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 Invesco Fund or of Invesco Ltd. or any of its subsidiaries.

Subject to any conditions or limitations imposed on the servicing of Class Y shares by your financial adviser, if you received Class Y shares as a result of a merger or reorganization of a predecessor fund into any of the Funds, you will be permitted to make additional Class Y share purchases. In addition, you will be permitted to make additional Class Y shares purchases if you owned Class Y shares in a “Solo 401(k)” Plan or 403(b) custodial account held directly at Invesco if you held such shares in your account on or prior to May 24, 2019.

Investor Class Shares

Investor Class shares are sold with no initial sales charge and have a maximum 12b-1 fee of 0.25%. Only the following persons may purchase Investor Class shares:

◾

Investors who established accounts prior to April 1, 2002, in Investor Class shares with Invesco Distributors, Inc. (Invesco Distributors) who have continuously maintained an account in Investor Class shares (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons) without a designated intermediary. These investors are referred to as “Investor Class grandfathered investors.”

◾

Customers of a financial intermediary that has had an agreement with the Funds’ distributor or any Funds that offered Investor Class shares prior to April 1, 2002, that has continuously maintained such agreement. These intermediaries are referred to as “Investor Class grandfathered intermediaries.”

◾

Any current, former or retired trustee, director, officer or employee (or immediate family member of a current, former or retired trustee, director, officer or employee) of any Invesco Fund or of Invesco Ltd. or any of its subsidiaries.

For additional shareholder eligibility requirements with respect to Invesco Premier Portfolio, please see “Shareholder Account Information – Purchasing Shares and Shareholder Eligibility – Invesco Premier Portfolio.”

Distribution and Service (12b-1) Fees

Except as noted below, each Fund has adopted a service and/or distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a Fund to pay distribution and service fees to Invesco Distributors to compensate or reimburse, as applicable, Invesco Distributors for its efforts in connection with the sale and distribution of the Fund’s shares, all or a substantial portion of which are paid to the dealer of record. Because the Funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cause you to pay more than the maximum permitted initial sales charges described in this prospectus.

The following Funds and share classes do not have 12b-1 plans:

◾

Invesco Limited Term Municipal Income Fund, Class A2 shares.

◾

Invesco Government Money Market Fund, Investor Class shares.

◾

Invesco Premier Portfolio, Investor Class shares.

◾

Invesco Premier U.S. Government Money Portfolio, Investor Class shares.

◾

All Funds, Class Y, Class R5 and Class R6 shares

Under the applicable service and/or distribution plan, the Funds may pay distribution and/or service fees up to the following annual rates with respect to each Fund’s average daily net assets with respect to such class (subject to the exceptions noted on page A-1):

◾

Class A shares: 0.25%

◾

Class C shares: 1.00%

◾

Class P shares: 0.10%

◾

Class R shares: 0.50%

◾

Class S shares: 0.15%

◾

Invesco Cash Reserve Shares: 0.15%

◾

Investor Class shares: 0.25%

Please refer to the prospectus fee table for more information on a particular Fund’s 12b-1 fees.

Initial Sales Charges (Class A Shares Only)

The Funds are grouped into six categories for determining initial sales charges. The “Other Information” section of each Fund’s prospectus will tell you the sales charge category in which the Fund is classified. Additionally, Class A shares of Invesco Conservative Income Fund and Invesco Short Term Municipal Fund do not have initial sales charges. As used below, the term “offering price” with respect to all categories of Class A shares includes the initial sales charge.

If you purchase $1,000,000 or more of Class A shares of Category I, II or V Funds or $250,000 or more of Class A shares of Category IV or VI Funds (a Large Purchase) the initial sales charge set forth below will be waived; though your shares will be subject to a 1% CDSC if you don’t hold such shares for at least 18 months.

Class A Shares Sold Without an Initial Sales Charge

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 following types of investors may purchase Class A shares without paying an initial sales charge:

Waivers Offered by the Fund
